‘Green’ Mediterranean diet benefits may arise from ‘hunger hormone’
A “green” adaptation to the traditional Mediterranean diet could help improve insulin sensitivity and reduce visceral fat by increasing levels of ghrelin, the “hunger hormone,” new research suggests.
The current study is a new analysis of data from the randomized DIRECT-PLUS trial, which showed that the addition of green tea and substitution of red meat for a plant-based (Mankai) protein shake at dinner – dubbed the “green Mediterranean diet” – resulted in further improved cardiometabolic benefits compared with the traditional Mediterranean diet among people with baseline abdominal obesity and/or dyslipidemia, according to the researchers.
They specifically looked at ghrelin, nicknamed the “hunger hormone,” a neuropeptide mainly secreted by the gastric epithelium. It acts on the pituitary gland to release growth hormone. Ghrelin concentrations increase during fasting and decrease after eating. Lower levels are associated with insulin resistance and obesity.
Fasting ghrelin levels were elevated with weight loss, but those increases were associated with improved insulin sensitivity and regression of visceral adipose tissue even beyond weight loss.
Although the caloric restriction and weight loss were comparable with the two Mediterranean diets, the green Mediterranean diet group had double the increase in fasting ghrelin as the traditional Mediterranean diet group, the researchers point out in their report .
‘Hypothesis-generating’ study pushes many hot topic buttons
“This specific study is the first to show that ghrelin levels play an important role in metabolic adaptation to a dietary or lifestyle intervention and that ghrelin is an important player in the axis of adiposity, insulin resistance, and metabolic health,” lead researcher Gal Tsaban, MD, told this news organization.
The data partially explain some of the prior beneficial effects seen with the Green Mediterranean diet, even after adjustment for weight loss, he explained, noting that the revised version of the diet “could be considered as an alternative lifestyle intervention with possible metabolic benefits even beyond the Mediterranean diet, which is what we currently recommend for patients.”
Asked for comment, Christopher Gardner, PhD, was not as enthusiastic.
He took issue with the fact that ghrelin wasn’t a primary or even a prespecified secondary outcome of the DIRECT-PLUS trial and because the specific plant-based ingredients of the green Mediterranean diet used in the study may not be widely available or desirable and therefore limit the study’s generalizability.
Dr. Gardner, who is director of nutrition studies at the Stanford Prevention Research Center, California, also said: “They’re tying lots of interesting things together. The Mediterranean diet is a cool thing, ghrelin is a cool thing, and insulin resistance is hugely important in this day and age, even though we don’t all agree on how to measure it.”
“But it gets tough as you try to link them all together for an exploratory outcome. ... To me it’s an interesting hypothesis-generating study that pushes a lot of interesting buttons that are hot topics in the field.”
Green Mediterranean diet led to higher ghrelin, metabolic benefits
In DIRECT-PLUS, a total of 294 adults (88% men) older than 30 years of age with abdominal obesity (waist circumference >102 cm for men or >88 cm for women), or dyslipidemia (triglycerides >150 mg/dL and HDL-cholesterol ≤40 mg/dL for men or ≤50 mg/dL for women) were included. Half had prediabetes or type 2 diabetes.
They were randomized to one of three diets: a diet based on standard healthy dietary guidelines; a traditional Mediterranean diet low in simple carbohydrates, rich in vegetables, with poultry and fish replacing beef and lamb and 28 g/day of walnuts; or the Green-Mediterranean diet, including 3-4 cups/day of green tea and 100 g/day of a green shake made from the Mankai strain of Wolffia globosa (also known as duckweed) replacing dinner, and 28 g/day of walnuts.
The Green Mediterranean diet included 800 mg more polyphenols than the traditional Mediterranean diet. Both were equally calorie-restricted, at about 1,500-1,800 kcal/day for men and 1,200-1,400 kcal/day for women. All three groups were instructed to engage in regular physical activity and were given free gym memberships.
The retention rate was 98.3% after 6 months and 89.8% after 18 months.
Weight loss was similar between the two Mediterranean diet groups (2.9% and 3.9% for the traditional and green versions, respectively) compared with the standard healthy diet (0.6%) (P < .05 for both Mediterranean diet groups vs. control).
After 6 months, fasting ghrelin increased in the traditional (8.0%; P = .015) and green (10.5%; P = 0.031) Mediterranean groups versus baseline, with no significant change in the control group.
By 18 months, fasting ghrelin was significantly greater compared with baseline only in the green Mediterranean group (P = .012).
Because the differences in fasting ghrelin trajectories were only significant in men – likely due to the small sample size of women – a subsequent 18-month analysis was limited to the men. In a multivariate model adjusted for age, intervention group, baseline biomarker values, and 18-month weight changes, the 18-month change in fasting ghrelin remained a significant predictor for changes in A1c and homeostatic model of insulin resistance (HOMA-IR; P = .022).
Because weight loss remained the most significant predictor of improved insulin resistance, a further analysis examined the association between changes in fasting ghrelin levels with changes in the fraction of insulin resistance marker that were not attributed to weight loss, per se. With the other adjustments, fasting ghrelin was associated with residual reductions in A1c (P = .003), HOMA-IR (P = .021), increased HDL-cholesterol (P = .024), and relative visceral adipose tissue loss (P = .003).
No specific product needed to push Mediterranean diet towards vegan
Dr. Tsaban, a nutritional researcher and cardiologist at Ben-Gurion University and Soroka University Medical Center, Be’er-Sheva, Israel, said the Mankai shake is commonly consumed in Israel but is also available worldwide. The study participants, all employees at an isolated nuclear research facility in the Negev, were particularly motivated. “They didn’t have a satiety problem with the drink. It made them very full,” he said. The manufacturer supplied the shakes but didn’t fund the study, he added.
However, Dr. Tsaban said that the “green Mediterranean diet” doesn’t depend on specific products.
Rather, “the concept is to push the Mediterranean diet a bit further and to replace the animal-based protein with vegetable-based protein, to shift your dietary habits towards a more vegan lifestyle. It’s not completely vegan, but it’s trending there. ... Our main goal was to increase the polyphenol intake, the antioxidant intake from vegetables. ... I think it can be replicated.”
Dr. Gardner said, “At the end of the day, it’s an exploratory study. ... It raises some interesting points that give the rest of us room to follow-up on.”
The study was funded by grants from the German Research Foundation, the Israel Ministry of Health, the Israel Ministry of Science and Technology, and the California Walnut Commission. Dr. Tsaban has reported no further relevant financial relationships. Dr. Gardner has reported receiving study funding from Beyond Meat.

Some diuretics tied to increased skin cancer risk
The findings were originally reported in two Danish case-control studies in which physicians reported a fourfold increased risk of squamous cell carcinoma, and a moderate increased risk of basal cell carcinoma and cutaneous malignant melanoma in patients who used hydrochlorothiazide long-term.
And, while the new study did not find an increased risk of basal cell carcinoma and cutaneous malignant melanoma among long-term users of hydrochlorothiazide, they suggest that bendroflumethiazide “may be a safer alternative for patients at increased risk of skin cancer.” The long-term use of indapamide was associated with a moderately increased risk of cutaneous malignant melanoma but did not alter the risk of either squamous cell or basal cell carcinoma
“Our results suggest that bendroflumethiazide may be a safer alternative to hydrochlorothiazide and indapamide, especially for patients at increased risk of skin cancer, but future studies are needed to rule out a causal association between bendroflumethiazide and cutaneous malignant melanoma,” wrote authors who were led by Christoph R. Meier, PhD, a professor in pharmacy with University Hospital Basel (Switzerland) and a contributor to the Boston Collaborative Drug Surveillance Program.
This study adds to existing evidence that there is a dose-dependent increased risk of squamous cell carcinoma in users of high cumulative doses of hydrochlorothiazide, compared with non–hydrochlorothiazide users.
The study, an observational cohort study, was published earlier this year. It is based on data from the U.K.-based Clinical Practice Research Datalink. It included 271,154 new users of thiazides and thiazidelike diuretics, the majority at 87.6% having been prescribed bendroflumethiazide, 5.8% indapamide, and 3.6% hydrochlorothiazide. Outcomes were compared to those observed in 275,263 users of calcium channel blockers.
“The three primary outcomes of interest were a first-time diagnosis of cutaneous malignant melanoma, basal cell carcinoma, or squamous cell carcinoma,” the authors wrote.
Incidence rates and incidence rate ratios were estimated for both short-term and long-term users of thiazidelike diuretics and calcium channel blockers, while a propensity score (PS) analysis was done in order to control for 23 baseline covariates. The mean follow-up after PS weighting was 3.9 years for indapamide users and 5.5 years for hydrochlorothiazide users. Overall, the incidence rate ratios of squamous cell carcinoma were not markedly increased for either short-term or long-term users of thiazidelike diuretics, the authors reported.
In contrast, the incidence rate ratios of squamous cell carcinoma for hydrochlorothiazide users were increased by 29% for short-term users at an IRR of 1.29 while they were increased by almost twofold for long-term hydrochlorothiazide users at an IRR of 1.95.
Long-term use of hydrochlorothiazide was again associated with a 64% increased risk of basal cell carcinoma, compared with users of a renin-angiotensin inhibitor at a weighted IRR of 1.64.
In contrast, weighted incident rate ratios for basal cell carcinoma for both short-term and long-term thiazide users were not significantly different and results were similar for patients who took hydrochlorothiazide, indapamide, or bendroflumethiazide.
Weighted overall incident rate ratios for cutaneous malignant melanoma were not significantly different for either short-term or long-term users of thiazidelike diuretics, compared with calcium channel blocker users.
However, there was a 43% increased risk of cutaneous malignant melanoma among long-term indapamide users at a weighted IRR of 1.43, compared with calcium channel blocker users, the authors reported.
“Given the biological plausibility and the severe clinical implications of cutaneous malignant melanoma, this finding should be considered carefully,” they cautioned.
Limitations to the study include the fact that the database analyzed does not have information on sun exposure, skin characteristics, or socioeconomic status which may affect the amount of sun exposure participants received.
The authors had no conflicts of interest to declare.

Stress, depression during pregnancy can harm child
New evidence points to the importance of helping mothers with their mental health during pregnancy.
Researchers from the National Institutes of Health in Bethesda, Md., have found that feelings of stress or depression while pregnant are linked to changes in the placenta where the child is growing. The findings, published in Epigenomics, show these changes could alter gene activity.
Stress and depression are not uncommon among expectant women, with depression affecting an estimated 1 in 10 pregnancies, according to the American College of Obstetricians and Gynecologists.
And current evidence already suggests that depression during pregnancy can negatively affect a child later in life. For instance, one study found that depression during pregnancy was linked to behavioral and emotional disorders during childhood, and another found that it raised the risk of depression at age 18.
To investigate stress and depression during pregnancy, the NIH investigators evaluated 301 pregnant women from 12 clinics in the United States who had taken part in an earlier clinical study. The group was ethnically diverse, with 34% identifying as Hispanic, 26% as non-Hispanic White, 24% as non-Hispanic Black, and 17% as Asian or Pacific Islander.
At the start of the study, the women were asked to complete questionnaires routinely used to screen for stress and depression. They completed the questionnaire five more times during their pregnancies. Shortly after each woman gave birth, researchers took tissue samples from the placenta and analyzed the genetics.
The purpose of studying the placenta, according to lead researcher Markos Tesfaye, MD, a postdoctoral fellow at the NIH, is that chemical changes can regulate whether a nearby gene can be activated.
There is evidence that chemical modifications in the placenta can lead to changes in fetal tissues, such as the brain, he said. And the placenta is known for making neurotransmitters, which are needed for fetal brain development.
The team found 16 areas where changes to the exterior of placental DNA were linked to depression in the second or third trimester. They also found two areas where these changes were associated with stress in the third trimester.
“Maternal depression leaves signals in the placenta at genes critical for fetal brain programming,” said study author Fasil Tekola-Ayele, PhD, from the NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development.
Two of the chemical changes linked to depression were near genes that are known to be involved with fetal brain development and neurologic and psychiatric illnesses.
“The findings illustrate that the developing fetus is sensitive to the mother›s condition during pregnancy, including maternal symptoms of low mood and perceived stress,” said Thalia K. Robakis, MD, from the women’s mental health program at Icahn School of Medicine at Mount Sinai, New York, who was not involved in the study.
But Dr. Robakis cautioned that no clinical outcomes were measured among the babies born, meaning that the study could not document any effects of maternal depression and stress on fetal development. Rather, the work contributes to figuring out what mechanisms are involved.
“Pregnant women should continue to focus on optimizing their own physical and mental health,” Dr. Robakis said. “And they should know that a happy, healthy mother is the most important factor supporting the development of a happy, healthy baby.”

New evidence points to the importance of helping mothers with their mental health during pregnancy.
Researchers from the National Institutes of Health in Bethesda, Md., have found that feelings of stress or depression while pregnant are linked to changes in the placenta where the child is growing. The findings, published in Epigenomics, show these changes could alter gene activity.
Stress and depression are not uncommon among expectant women, with depression affecting an estimated 1 in 10 pregnancies, according to the American College of Obstetricians and Gynecologists.
And current evidence already suggests that depression during pregnancy can negatively affect a child later in life. For instance, one study found that depression during pregnancy was linked to behavioral and emotional disorders during childhood, and another found that it raised the risk of depression at age 18.
To investigate stress and depression during pregnancy, the NIH investigators evaluated 301 pregnant women from 12 clinics in the United States who had taken part in an earlier clinical study. The group was ethnically diverse, with 34% identifying as Hispanic, 26% as non-Hispanic White, 24% as non-Hispanic Black, and 17% as Asian or Pacific Islander.

Itepekimab reduces loss of asthma control
For patients with moderate to severe asthma, blockade with itepekimab, a new human IgG4P monoclonal antibody against the upstream alarmin interleukin-33, led to a reduction in events that indicate loss of asthma control. Treatment with itepekimab also led to an improvement in lung function compared with placebo, according to results of a phase 2 trial.
However, findings for a subgroup of patients treated with itepekimab in combination with dupilumab, an anti–interleukin-4–receptor alpha subunit and IL-13 monoclonal antibody, were not favorable in comparison with placebo, noted M. E. Wechsler, MD, and colleagues in an article published online in the New England Journal of Medicine.
New target
Despite the demonstrated efficacy of available biologic therapies targeting IgE, interleukin-4, interleukin-13, and interleukin-5 for treating moderate to severe type 2 asthma, many patients with type 2 or non–type 2 asthma continue to have symptoms, exacerbations, and reduced lung function. New therapies targeting alternative pathophysiologic pathways are needed.
Genomewide studies show that type 2 and non–type 2 inflammation that contributes to asthma and chronic obstructive pulmonary disease (COPD) are genetically associated with interleukin-33. This inflammation occurs when interleukin-33 binds to its cognate receptor (ST2) and engages the coreceptor interleukin-1 receptor accessory protein to initiate downstream signaling, activating cells of both the innate and adaptive immune systems.
Study details
The investigators conducted a multicenter, randomized, double-blind, placebo-controlled, parallel-group (four groups), proof-of-concept trial to evaluate the efficacy and safety of the interleukin-33 targeting itepekimab in comparison with placebo for adults with moderate to severe asthma. Dupilumab, which was the active comparator, was administered in combination with itepekimab to evaluate potential additive effects. Dupilumab’s efficacy in this population had been demonstrated previously.
All 296 patients (mean age, 49.1 years; 64% women) were receiving inhaled glucocorticoids plus long-acting beta-agonists (LABAs). They were randomly assigned in a 1:1:1:1 ratio to receive subcutaneous itepekimab (300 mg), itepekimab plus dupilumab (both at 300 mg; combination therapy), dupilumab (300 mg), or placebo every 2 weeks for 12 weeks. LABAs were discontinued at week 4, and inhaled glucocorticoids were tapered over weeks 6 through 9. The primary endpoint was the occurrence of an event indicating the loss of asthma control.
Promising results
Primary endpoint analysis at 12 weeks revealed a lower rate of asthma control–loss events in the itepekimab and dupilumab monotherapy groups but not in the combination group, compared with patients who received placebo. Events occurred in 22% of patients in the itepekimab group, in 27% of those in the combination group, in 19% of the dupilumab group, and in 41% of the placebo group. The odds ratios for comparisons with placebo were 0.42 for the itepekimab group (95% confidence interval, 0.20-0.88; P = .02); 0.33 in the dupilumab group (95% CI, 0.15-.70); and 0.52 in the combination group (95% CI, 0.26-1.06; P = .07) .
Following a similar pattern, forced expiratory volume in 1 second before use of a bronchodilator increased with both monotherapies but not with the combination or placebo. Although the trial was not powered to determine differences between itepekimab and dupilumab, the effects of dupilumab therapy were generally greater than those observed with itepekimab, especially for patients with type 2 asthma.
Also, asthma control and quality of life were improved with itepekimab and dupilumab monotherapy in comparison with placebo. There were also greater reductions in the mean blood eosinophil count.
The authors urge further research into the complexities of asthma physiology and encourage researchers to look for predictive biomarkers of anti–interleukin-33 blockade response. They conclude, “In this trial, we found that itepekimab monotherapy led to a lower incidence of events indicating loss of asthma control and to improved lung function, findings that are consistent with a role for interleukin-33 in the pathogenesis of exacerbations and airflow limitation in asthma.”
Examining results
In an accompanying editorial, Philip G. Bardin, PhD, and Paul S. Foster, DSc, ask why itepekimab and dupilumab, a combination based on a sound scientific rationale, failed. As monotherapies, both itepekimab and dupilumab are roughly similar in reducing asthma events and improving lung function; thus, is unlikely that inadequate dosing led to the failure of itepekimab.
Interleukin-33 is an attractive target because the cells it promotes secrete cytokines that induce asthma’s pathognomonic features, and biologic agents that target those cytokines (interleukin-5/-5R/-4/-13 axes) have been highly effective. They do not, however, prevent exacerbations after treatment.
Alternative pathways within or outside that paradigm are operant, and other epithelial alarmins, such as interleukin-25 and thymic stromal lymphopoietin, promote type 2 inflammation, Dr. Bardin and Dr. Foster state.
“Combination therapy with itepekimab and dupilumab may have failed because these pathways bypass interleukin-33,” they write. Also, preexisting ILC2 and TH2 cells may have residual capacity to release mediators. The short-term trial design, the editorialists write, may have contributed to the failure of the itepekimab/dupilumab combination; interleukin-33 may be appropriate as a target in a longer-term exacerbation-type trial “in which epithelial infection and other relevant stimuli instigate exacerbated disease. Combination therapy may be capable of lowering exacerbations rather than preventing loss of control in chronic disease.
“Clinical translation of basic science in asthma remains a challenge to be pursued. ... It is imperative to harness scientific insights from translational studies that frustrate our hopeful expectations – so that something can also be gained,” they conclude.
The role of interleukin-33
“Our study of itepekimab provides valuable insight into pathophysiology of severe asthma,” said Dr. Wechsler, professor of medicine at the NJH Cohen Family Asthma Institute, Denver, in an interview. “As blocking IL-33 reduced asthma worsening and improved lung function compared to placebo, it suggests that IL-33 plays an important role in asthma pathophysiology and may be a valuable target for a subset of patients with severe asthma,” he stated.
“Since the effect of itepekimab is comparable to that of dupilumab, it is suggested that patients may benefit from blockade of this pathway, but what remains to be seen is identifying which patients are more likely to respond better to one therapy vs. another. The future of blocking IL-33 remains exciting, and studies are being planned to evaluate its efficacy in airways diseases, including COPD,” he concluded.

Placebo beat risankizumab in adults with severe asthma
Placebo treatment was found to be superior to treatment with risankizumab with respect to time to first asthma worsening and annualized rate of asthma worsening for adults with severe persistent asthma in a phase 2a clinical trial.
The randomized, double-blind, 24-week, parallel group, multicenter trial assessed risankizumab efficacy and safety in 214 adults with severe persistent asthma. The results were reported in The New England Journal of Medicine.
Risankizumab is a humanized, monoclonal antibody directed against subunit p19 of interleukin-23. It is approved for the treatment of moderate to severe psoriasis.
Interleukin-23 has been implicated in airway inflammation mediated by type 2 and type 17 cytokines. Noting that inhibition of interleukin-23 is effective in the treatment of psoriasis and Crohn’s disease, Christopher E. Brightling, MD, and colleagues investigated whether targeting interleukin-23 in asthma patients would improve disease control and reduce airway inflammation.
Study details
Patients received either 90 mg of risankizumab (subcutaneous) (n = 105) or placebo (n = 109) once every 4 weeks. Time to first asthma worsening was the primary endpoint. Worsening was defined as decline from baseline on 2 or more consecutive days. Deterioration was defined as a decrease of at least 30% in the morning peak expiratory flow or an increase from baseline of at least 50% in rescue medication puffs over 24 hours. In addition, a severe asthma exacerbation or an increase of 0.75 or more points on the five-item Asthma Control Questionnaire (scores range from 0 to 6, with higher scores indicating less control) were considered to be evidence of worsening. Annualized rate of asthma worsening was a secondary endpoint.
The mean age of the patients was 53 years; 66.5% of the patients were women.
Disappointing results
In the risankizumab group, median time to first asthma worsening was 40 days, significantly worse than the 86 days reported for the placebo group (hazard ratio, 1.46; 95% confidence interval, 1.05-2.04; P = .03). For annualized asthma worsening, the rate ratio for the comparison of risankizumab with placebo was 1.49 (95% CI, 1.12-1.99).
Among key secondary endpoints, the adjusted mean change in trough forced expiratory volume in 1 second (FEV1) from baseline to week 24 was –0.05 L in the risankizumab group and –0.01 L in the placebo group. The adjusted mean change in FEV1 after bronchodilator use from baseline to week 24 was –0.10 L in the risankizumab group and –0.03 L in the placebo group. Sputum transcriptomic pathway analysis showed that genes involved in the activation of natural killer cells and cytotoxic T cells and the activation of type 1 helper T and type 17 helper T transcription factors were downregulated by risankizumab. Rates of adverse events were similar among patients receiving risankizumab and those taking placebo.
Further trials unwarranted
“The findings not only failed to show benefit for any outcome but also showed asthma worsening occurred earlier and more frequently in those treated with risankizumab versus placebo,” Dr. Brightling, professor in the department of respiratory sciences at University of Leicester, England, said in an interview. “This study does not support any further trials for anti-IL23 in asthma.” Dr. Brightling speculated on the cause of accelerated asthma worsening with risankizumab.
“We found that the gene expression of key molecules involved in our response to infection was decreased in airway samples in those treated with risankizumab versus placebo. It is possible that the increased asthma worsening following risankizumab was related to this suppression of antimicrobial immunity,” he said.
He noted that risankizumab did not affect type-2/eosinophilic inflammation, which is the target for current asthma biologics, or gene expression of T2 molecules. “That suggests that this type of inflammation would have continued in the asthma patients during the trial irrespective of receiving risankizumab or placebo,” he said.
Caution with investigating biologicals
Downstream biologic responses to risankizumab were detectable, Philip G. Bardin, PhD, and Paul S. Foster, DSc, observed in an accompanying editorial, but there was no discernible clinical benefit, implying attenuation of apposite pathways. Current understanding of the basic science relevant to asthma, they stated, offers clues to the failure of risankizumab to benefit these patients with severe asthma. Although targeting the interleukin-23 and Th17 axis with risankizumab can reduce development of pathogenic Th17 cells, interleukin-23 is not critical for the development of Th17 cells.
“In contrast to pathways operated by interleukin-5 and interleukin-4R alpha, interleukin-23 has only a limited auxiliary role in amplifying type 2 responses. It is possible that the trial conducted by Brightling and colleagues failed because signaling through alternative disease pathways nullified inhibition of inter-leukin-23,” the editorialists wrote.
Dr. Bardin and Dr. Foster further speculate that because interleukin-23 is vital for effective mucosal immunity, risankizumab may have conferred to patients a predisposition to more severe or more frequent virus-induced exacerbations. They stated that generally, however, the reasons for risankizumab’s poorer outcomes compared to placebo are unclear. “Overall, these findings support a cautious approach in future research investigating biologic therapies in asthma,” they concluded.
The clinical trial was sponsored and funded by BI/AbbVie.

Risankizumab is a humanized, monoclonal antibody directed against subunit p19 of interleukin-23. It is approved for the treatment of moderate to severe psoriasis.
Interleukin-23 has been implicated in airway inflammation mediated by type 2 and type 17 cytokines. Noting that inhibition of interleukin-23 is effective in the treatment of psoriasis and Crohn’s disease, Christopher E. Brightling, MD, and colleagues investigated whether targeting interleukin-23 in asthma patients would improve disease control and reduce airway inflammation.
Study details
Patients received either 90 mg of risankizumab (subcutaneous) (n = 105) or placebo (n = 109) once every 4 weeks. Time to first asthma worsening was the primary endpoint. Worsening was defined as decline from baseline on 2 or more consecutive days. Deterioration was defined as a decrease of at least 30% in the morning peak expiratory flow or an increase from baseline of at least 50% in rescue medication puffs over 24 hours. In addition, a severe asthma exacerbation or an increase of 0.75 or more points on the five-item Asthma Control Questionnaire (scores range from 0 to 6, with higher scores indicating less control) were considered to be evidence of worsening. Annualized rate of asthma worsening was a secondary endpoint.
The mean age of the patients was 53 years; 66.5% of the patients were women.
Disappointing results
In the risankizumab group, median time to first asthma worsening was 40 days, significantly worse than the 86 days reported for the placebo group (hazard ratio, 1.46; 95% confidence interval, 1.05-2.04; P = .03). For annualized asthma worsening, the rate ratio for the comparison of risankizumab with placebo was 1.49 (95% CI, 1.12-1.99).
Among key secondary endpoints, the adjusted mean change in trough forced expiratory volume in 1 second (FEV1) from baseline to week 24 was –0.05 L in the risankizumab group and –0.01 L in the placebo group. The adjusted mean change in FEV1 after bronchodilator use from baseline to week 24 was –0.10 L in the risankizumab group and –0.03 L in the placebo group. Sputum transcriptomic pathway analysis showed that genes involved in the activation of natural killer cells and cytotoxic T cells and the activation of type 1 helper T and type 17 helper T transcription factors were downregulated by risankizumab. Rates of adverse events were similar among patients receiving risankizumab and those taking placebo.
Further trials unwarranted
“The findings not only failed to show benefit for any outcome but also showed asthma worsening occurred earlier and more frequently in those treated with risankizumab versus placebo,” Dr. Brightling, professor in the department of respiratory sciences at University of Leicester, England, said in an interview. “This study does not support any further trials for anti-IL23 in asthma.” Dr. Brightling speculated on the cause of accelerated asthma worsening with risankizumab.
“We found that the gene expression of key molecules involved in our response to infection was decreased in airway samples in those treated with risankizumab versus placebo. It is possible that the increased asthma worsening following risankizumab was related to this suppression of antimicrobial immunity,” he said.
He noted that risankizumab did not affect type-2/eosinophilic inflammation, which is the target for current asthma biologics, or gene expression of T2 molecules. “That suggests that this type of inflammation would have continued in the asthma patients during the trial irrespective of receiving risankizumab or placebo,” he said.
Caution with investigating biologicals
Downstream biologic responses to risankizumab were detectable, Philip G. Bardin, PhD, and Paul S. Foster, DSc, observed in an accompanying editorial, but there was no discernible clinical benefit, implying attenuation of apposite pathways. Current understanding of the basic science relevant to asthma, they stated, offers clues to the failure of risankizumab to benefit these patients with severe asthma. Although targeting the interleukin-23 and Th17 axis with risankizumab can reduce development of pathogenic Th17 cells, interleukin-23 is not critical for the development of Th17 cells.
“In contrast to pathways operated by interleukin-5 and interleukin-4R alpha, interleukin-23 has only a limited auxiliary role in amplifying type 2 responses. It is possible that the trial conducted by Brightling and colleagues failed because signaling through alternative disease pathways nullified inhibition of inter-leukin-23,” the editorialists wrote.
Dr. Bardin and Dr. Foster further speculate that because interleukin-23 is vital for effective mucosal immunity, risankizumab may have conferred to patients a predisposition to more severe or more frequent virus-induced exacerbations. They stated that generally, however, the reasons for risankizumab’s poorer outcomes compared to placebo are unclear. “Overall, these findings support a cautious approach in future research investigating biologic therapies in asthma,” they concluded.
The clinical trial was sponsored and funded by BI/AbbVie.

Ohio records more deaths than births for first time
In 2020, around 143,661 Ohioans died and 129,313 Ohioans were born, according to The Columbus Dispatch. The trend appears to have continued so far this year, with 107,462 deaths and 100,781 births reported to date.
Deaths haven’t surpassed births in the 112 years since the state began compiling data in 1909, the newspaper reported. The state’s birth rate has been declining for years while the number of deaths has risen, though data shows that the COVID-19 pandemic accelerated the shift.
“It doesn’t surprise me at all,” Joseph Gastaldo, MD, the medical director of infectious diseases for OhioHealth, told the newspaper.
Ohio’s birth rate fell by 4% in 2020, which defied public expectations about a pandemic birth boom. In addition, the state reported 13,927 COVID-19 deaths throughout the year.
“It’s COVID, clearly,” he noted.
Alabama also recorded more deaths than births for the first time last year, according to The New York Times. The state reported 64,714 deaths and 57,641 births in 2020.
“Our state literally shrunk in 2020,” Scott Harris, MD, the state health officer for Alabama, said at a news conference in September.
The state had never recorded a gap that large, even during World War I, World War II, and the 1918 flu pandemic, he said. Alabama has kept records on the numbers since 1900.
“We’ve never had a time when deaths exceeded births,” Dr. Harris said.
In fact, about half of U.S. states reported death rates higher than birth rates in 2020, according to a recent study from researchers at the University of New Hampshire. In 2019, only five states --Maine, New Hampshire, Rhode Island, Vermont, and West Virginia -- reported more deaths than births.
In 2020, the United States reported a record of nearly 3.4 million deaths, which was 18% more than in 2019, the researchers found. COVID-19 was the primary reason for the increase in deaths, accounting for about 11% of total deaths. Meanwhile, births dropped by 4% to about 3.6 million.
The surplus of births over deaths added 229,000 people to the U.S. population in 2020, as compared to 892,000 in 2019, which means the country’s population growth slowed last year. The decline, paired with lower immigration rates during the pandemic, led to the smallest annual percentage population gain in at least 100 years.
“Deaths will likely exceed births again in many states in 2021,” Kenneth Johnson, PhD, a senior demographer and study author, wrote in a statement.
“How large or protracted these fertility declines and mortality increases will be remains to be seen, but they have already dramatically reduced population growth in the United States,” he said.

Risk-based antenatal type-and-screen blood testing safe and economical
Implementing a selective type-and-screen blood testing policy in the labor and delivery unit was associated with projected annual savings of close to $200,000, a large single-center study found. Furthermore, there was no evidence of increased maternal morbidity in the university-based facility performing more than 4,400 deliveries per year, according to Ashley E. Benson, MD, MA, of the department of obstetrics and gynecology at the University of Utah, Salt Lake City, and colleagues.
The study, published in Obstetrics & Gynecology, evaluated patient safety, resource utilization, and transfusion-related costs after a policy change from universal type and screen to selective, risk-based type and screen on admission to labor and delivery.
“There had been some national interest in moving toward decreased resource utilization, and findings that universal screening was not cost effective,” Dr. Benson, who has since relocated to Oregon Health & Science University, Portland, said in an interview. An earlier cost-effective modeling study at her center had suggested that universal test and screen was not cost effective and likely not safer either. “So based on that data we felt an implementation study was warranted.”
The switch to a selective policy was made in 2018, after which her group compared outcomes from October 2017 to September 2019, looking those both 1 year preimplementation and 1 year post implementation.
One year post implementation, the following outcomes emerged, compared with preimplementation:
- Overall projected saving of $181,000 a year in the maternity unit
- Lower mean monthly type- and screen-related costs, such as those for ABO typing, antibody screen, and antibody workup. cross-matches, hold clots, and transfused products: $9,753 vs. $20,676 in the preimplementation year (P < .001)
- A lower mean monthly cost of total transfusion preparedness: $25,090 vs. $39,211 (P < .001)
- No differences in emergency-release transfusion events (four vs. three, P = .99),the study’s primary safety outcome
- Fewer emergency-release red blood cell units transfused (9 vs. 24, P = .002) and O-negative RBC units transfused (8 vs. 18, P = .016)
- No differences in hysterectomies (0.05% vs. 0.1%, P = .44) and ICU admissions (0.45% vs. 0.51%, P = .43)
“In a year of selective type and screen, we saw a 51% reduction in costs related to type and screen, and a 38% reduction in overall transfusion-related costs,” the authors wrote. “This study supports other literature suggesting that more judicious use of type and screen may be safe and cost effective.”
Dr. Benson said the results were positively received when presented a meeting 2 years ago but the published version has yet to prompt feedback.
The study
Antepartum patients underwent transfusion preparedness tests according to the center’s standard antenatal admission order sets and were risk stratified in alignment with California Maternal Quality Care Collaborative recommendations. The mean maternal age of patients in both time periods was similar at just over 29 years and the mean gestational age at delivery was just under 38 weeks.
Under the new policy, a “hold clot” is obtained for women stratified as low or medium risk on admission. In this instance, a tube of patient blood is held in the blood bank but processed only if needed, as in the event of active hemorrhage or an order for transfusion. A blood cross-match is obtained on all women stratified as high risk or having a prior positive antibody screen.
Relevant costs were the direct costs of transfusion-related testing in the labor and delivery unit from a health system perspective.
Obstetric hemorrhage is the leading cause of maternal death worldwide, the authors pointed out. While transfusion in obstetric patients occurs in only 1% or 2% of all deliveries it is nevertheless difficult to predict which patients will need transfusion, with only 2%-8% of those stratified as high risk ultimately requiring transfusion. Although obstetric hemorrhage safety bundles recommend risk stratification on admission to labor and delivery with selective type and screen for higher-risk individuals, for safety and simplicity’s sake, many labor and delivery units perform universal type and screen.
The authors cautioned that these results occurred in an academic tertiary care center with systems fine-tuned to deal with active hemorrhage and deliver timely transfusable blood. “At the moment we don’t have enough data to say whether the selective approach would be safe in hospitals with more limited blood bank capacity and access and fewer transfusion specialists in a setting optimized to respond to emergent needs, Dr. Benson said.
Katayoun F. M. Fomani, MD, a transfusion medicine specialist and medical director of blood bank and transfusion services at Long Island Jewish Medical Center, New York, agreed. “This approach only works in a controlled environment such as in this study where eligible women were assessed antenatally at the same center, but it would not work at every institution,” she said in an interview. “In addition, all patients were assessed according to the California Collaborative guideline, which itself increases the safety level but is not followed everywhere.”
The obstetric division at her hospital in New York adheres to the universal type and screen. “We have patients coming in from outside whose antenatal testing was not done at our hospital,” she said. “For this selective approach to work you need a controlled population and the electronic resources and personnel to follow each patient carefully.”
The authors indicated no specific funding for this study and disclosed no potential conflicts of interest. Dr. Fomani had no potential competing interests to declare.

Relevant costs were the direct costs of transfusion-related testing in the labor and delivery unit from a health system perspective.
Obstetric hemorrhage is the leading cause of maternal death worldwide, the authors pointed out. While transfusion in obstetric patients occurs in only 1% or 2% of all deliveries it is nevertheless difficult to predict which patients will need transfusion, with only 2%-8% of those stratified as high risk ultimately requiring transfusion. Although obstetric hemorrhage safety bundles recommend risk stratification on admission to labor and delivery with selective type and screen for higher-risk individuals, for safety and simplicity’s sake, many labor and delivery units perform universal type and screen.
The authors cautioned that these results occurred in an academic tertiary care center with systems fine-tuned to deal with active hemorrhage and deliver timely transfusable blood. “At the moment we don’t have enough data to say whether the selective approach would be safe in hospitals with more limited blood bank capacity and access and fewer transfusion specialists in a setting optimized to respond to emergent needs, Dr. Benson said.
Katayoun F. M. Fomani, MD, a transfusion medicine specialist and medical director of blood bank and transfusion services at Long Island Jewish Medical Center, New York, agreed. “This approach only works in a controlled environment such as in this study where eligible women were assessed antenatally at the same center, but it would not work at every institution,” she said in an interview. “In addition, all patients were assessed according to the California Collaborative guideline, which itself increases the safety level but is not followed everywhere.”
The obstetric division at her hospital in New York adheres to the universal type and screen. “We have patients coming in from outside whose antenatal testing was not done at our hospital,” she said. “For this selective approach to work you need a controlled population and the electronic resources and personnel to follow each patient carefully.”
The authors indicated no specific funding for this study and disclosed no potential conflicts of interest. Dr. Fomani had no potential competing interests to declare.

Vitamin D status may play a pivotal role in colon cancer prevention
This is according to an observational study published in the journal Gastroenterology. The study included 94,205 women (aged 25-42 years) who were followed between 1991 and 2015 during which 111 incident cases of early-onset colorectal cancer were diagnosed. Among 29,186 women who had at least one lower endoscopy from 1991 to 2011, 1,439 newly diagnosed conventional adenomas and 1,878 serrated polyps were found.
Women who consumed the highest average levels of total vitamin D of 450 IU per day, compared with those consuming less than 300 IU per day, showed a significantly reduced risk of early-onset colorectal cancer. Consuming 400 IU each day was associated with a 54% reduced risk of early-onset colorectal cancer.
“If confirmed, our findings could potentially lead to recommendations for higher vitamin D intake as an inexpensive low-risk complement to colorectal cancer screening as a prevention strategy for adults younger than age 50,” wrote the study authors, led by Edward L. Giovannucci, MD, ScD, of the Harvard School of Public Health, Boston.
Associations between vitamin D levels and colorectal cancer have been documented in review articles over the years. The link is the subject of 10 recently completed or ongoing clinical trials. Few studies have focused on early colorectal cancer and vitamin D intake. Unlike advanced colorectal cancer, the early-onset form of the disease is not as strongly associated with the traditional risk factors of a family history of colorectal cancer and it is therefore believed to be more strongly linked to other factors, such as lifestyle and diet – including vitamin D supplementation.
The evidence is in, but it’s incomplete
In addition to the new study in Gastroenterology, other observational studies, as well as laboratory and animal studies, suggest that vitamin D plays a role in inhibiting carcinogenesis. Vitamin D, researchers theorize, contains anti-inflammatory, immunomodulatory, and tumor angiogenesis properties that can slow the growth of tumors, but the evidence is mixed.
A meta-analysis of 137,567 patients published in 2013 in Preventive Medicine found an inverse association between 25-hydroxyvitamin D (25[OH]D) and total cancer mortality in women, but not among men. Three meta-analyses published in 2014 and 2019 found that vitamin D supplementation does not affect cancer incidence but does significantly reduce total cancer mortality rates by 12%-13%.
In 2019, researchers led by Marjorie McCullough, ScD, RD, senior scientific director of epidemiology research for the American Cancer Society, described a causal relationship between circulating vitamin D and colorectal cancer risk among 17 cohorts from a pooled analysis. “Our study suggests that optimal circulating 25(OH)D concentrations for colorectal cancer risk reduction are 75-100 nmol/L, [which is] higher than current Institute of Medicine recommendations for bone health,” she and colleagues wrote. Their findings were published in the Journal of the National Cancer Institute.
The Vitamin D and Omega-3 Trial (VITAL) published in 2019 in the New England Journal of Medicine, showed no significant effect of vitamin D3 supplementation of 2,000 IU/day in lowering the risk of invasive cancer or cardiovascular events.
Despite the mixed results, studies offer valuable insights into cancer risks, said Scott Kopetz, MD, PhD, codirector of the colorectal cancer moon shot research program at the University of Texas MD Anderson Cancer Center, Houston.
The Gastroenterology study is noteworthy because it focuses on early-onset colorectal cancer, he said.
“[The authors] demonstrate for the first time that there is an association of vitamin D intake with early-onset colorectal incidence, especially in the left side of the colon and rectum where the increase in early onset colorectal cancer manifests,” Dr. Kopetz said. “The analysis suggests that it may require long-term vitamin D intake to derive the benefit, which may explain why some shorter-term randomized studies failed to demonstrate.”
In animal models, vitamin D3 is “estimated to lower the incidence of colorectal cancer by 50%,” according to Lidija Klampfer, PhD, formerly a molecular biologist and senior research scientist with the Southern Research Institute, Birmingham, Ala.
Dr. Klampfer, a founding partner of ProteXase Therapeutics, is the author of an article on vitamin D and colon cancer published in 2014 in the World Journal of Gastrointestinal Oncology.
“The levels of vitamin D3 appear to be an essential determinant for the development and progression of colon cancer and supplementation with vitamin D3 is effective in suppressing intestinal tumorigenesis in animal models,” she wrote. “Studies have shown that 1,25 dihydroxyvitamin D3 can inhibit tumor-promoting inflammation leading to the development and progression of colon cancer.”
The hazards of a vitamin D deficiency
A severe vitamin D deficiency is associated with compromised bone and muscle health, calcium absorption, immunity, heart function and it can affect mood. Other studies have linked vitamin D deficiency to colorectal cancer, blood cancers, and bowel cancer.
Serum 25(OH)D is the primary circulating form of vitamin D and is considered the best marker for assessing vitamin D status, says Karin Amrein, MD, MSc, an endocrinologist with the Medical University of Graz (Austria). She was the lead author of a review on vitamin D deficiency published in January 2020 in the European Journal of Clinical Nutrition.
The Global Consensus Recommendations define vitamin D insufficiency as 12-20 ng/mL (30-50 nmol/L) and a deficiency as a serum 25OHD concentration less than 12 ng/mL (30 nmol/L). A deficiency in adults is usually treated with 50,000 IU of vitamin D2 or D3 once weekly for 8 weeks followed by maintenance dosages of cholecalciferol (vitamin D3) at 800-1,000 IU daily from dietary and supplemental sources.
Screening is recommended for individuals who exhibit symptoms and conditions associated with a vitamin D deficiency, but there is little agreement on recommended serum levels because every individual is different, according to the U.S. Preventive Services Task Force which updated its vitamin D recommendations in April for the first time in 7 years.

Rachel Levine: Making History Every Step of the Way
“We each come to public service in our own unique way,” ADM Rachel Levine, MD, Assistant Secretary for Health at the US Department of Health and Human Services (HHS), told the Senate Health, Education, Labor and Pensions Committee at her confirmation hearing in February 2021.
In her case, unique and history-making. Levine was confirmed on Tuesday as the first-ever openly transgender—and firstwoman—four-star admiral in the history of the US Public Health Service Commissioned Corps. She is also the first openly transgender four-star officer and the first openly transgender person to be confirmed by the Senate. In fact, she is the nation’s highest-ranking openly transgender official—the first such across any of the eight uniformed services.
All those firsts aside, in her confirmation hearing remarks, ADM. Levine said, “At its core, my career has been about helping people live healthy lives.” She began her career at Mt. Sinai Medical Center in New York, in pediatric and adolescent medicine, focusing on mental and physical health. Moving to the Penn State College of Medicine, ADM Levine was a professor of pediatrics and psychiatry and vice-chair for clinical affairs for the Department of Pediatrics. At Penn State, she initiated the Division of Adolescent Medicine for the care of complex teens with medical and psychological problems. As chief of the Division of Adolescent Medicine and Eating Disorders at Penn State Hershey Medical Center, she also founded an eating disorders program, offering multidisciplinary treatment for children, adolescents, and adults.
In 2015, Pennsylvania Governor Tom Wolf nominated ADM Levine to be Physician General of the Commonwealth of Pennsylvania and she was confirmed unanimously by the state senate. In 2018, she was named Pennsylvania’s Secretary of Health. In these roles, she tackled the state’s massive opioid misuse and overdose crisis. She focused on opioid stewardship, developed continuing medical education programs, and established prescribing guidelines and a “robust” prescription drug monitoring program. She traveled extensively throughout small communities, doing public events with local officials and residents to talk about opioid abuse. The efforts began, slowly, to pay off. In 2015, 3,383 people died of drug overdose in Pennsylvania, a 23% increase from 2014. By 2018, 65% of drug overdose deaths involved opioids, but the total number of deaths fell to 2,866.
One of her most significant accomplishments as Physician General, Levine said, was to issue the first-ever statewide standing order for distribution of the anti-overdose drug naloxone, allowing law enforcement to carry the drug and Pennsylvania citizens to buy itover the counter. According to the Pennsylvania Opioid Data Dashboard, between January 1, 2018, and October 9, 2021, 62,954 doses of naloxone were administered by EMS.
In another of Levine’s projects, the Pennsylvania Rural Health Model, the goal was to move rural hospitals from fee-for-service models to global budget payments, which she said, “aligned incentives for providers to deliver value-based care and for rural hospitals to transform their care to better meet community health needs.”
Working in tandem with HHS, Levine’s teams also set up a maternal mortality review committee “to better understand and respond to the causes of maternal deaths,” and worked to improve childhood immunization rates.
“Of course, our focus changed dramatically last year,” Levine said, “and COVID-19 became my most urgent and primary focus.” She concentrated on three key priorities: containment with expansion of testing and contact tracing; mitigation with masks and distancing; and medical countermeasures, including monoclonal antibodies and vaccines. To carry out the strategies, she oversaw a health equity task force, which included community stakeholders such as the Black Coalition Against COVID-19, the Latino Connection, and a faith-based program that allowed people to get tested at their places of worship.
When lesbian, gay, bisexual, transgender, queer; lesbian, gay, bisexual, transgender, queer (LGBTQ+) advocates charged that states were not collecting data early in the pandemic on sexual orientation or gender identity, in another historic move, Levine announced in March 2020 that Pennsylvania would begin collecting demographic data on the coronavirus, making it the first state in the country to do so.
Levine has garnered praise from many sources. “This is a proud moment for us,” HHS Secretary Xavier Becerra said in a statement, calling her a “cherished and critical partner in our work to build a healthier America.” Alphonso David, then president of the Human Rights Campaign, said in a statement that Levine’s nomination to be the HHS Assistant Secretary for Health represented “real change” in the government’s approach to the coronavirus and LGBTQ+ health issues. Levine “led Pennsylvania’s public health response to the COVID-19 pandemic superbly,” he said.
She has also triggered a significant amount of outrage in conservative quarters. She was routinely castigated for her early actions in the pandemic. Writing for The American Spectator in May 2020, Paul Kengor, a former UPMC researcher, said UPMC’s overall handling of the virus was “impressive and inspired confidence.” However, tracking the data on fatalities, he said, he found the disproportionate number of deaths in nursing homes “alarming and strange.” Citing an investigative article in the Bucks County Courier Times, he blamed Pennsylvania officials—including Levine—for guidelines that directed licensed long-term care facilities to continue admitting new patients, including those discharged from hospitals back to nursing homes. However, Kengor claimed, the “partisan press” would protect Wolf and Levine: “Levine is a liberal darling as the nation’s first (and arguably highest-ranking) transgender public official.”
At the February 2021 federal confirmation hearing, Levine was pressed on data discrepancies in Pennsylvania’s public reports on nursing home coronavirus deaths and cases. Sen. Susan Collins (R-ME) cited Spotlight PA reporting that found weekly reports released by the state health department were consistently missing data for more than 100 of the 693 nursing homes. Levine, in response, pointed to lags in the state’s electronic death reporting system and to slow uploads. Pennsylvania health officials also referred to a state law that prohibits the release of disease records by state or local authorities.
In a June 2020 opinion article, Levine wrote that the Pennsylvania Health Department had followed Centers for Disease Control and Prevention (CDC) guidance, including limiting outside people from entering long-term care facilities. The Pennsylvania Health Department also sent thousands of shipments of personal protective equipment and conducted virtual inspections, including on-site inspections as warranted.
Despite those efforts, Levine said, “staff members who have dedicated their lives to caring for these vulnerable Pennsylvanians unknowingly contracted COVID-19 in their communities and carried it into these facilities.” She pointed out that residents who returned from hospitals had been isolated if they contracted COVID-19. Patients returning to nursing homes did not introduce COVID-19, Levine said, “because it was there that they first came into contact with the virus.” Moreover, those patients were isolated, just as they had been before they required hospital-level care, she added.
When a long-term care facility reports a case of COVID-19, Levine noted, the Pennsylvania Health Department considers it an outbreak and offers a variety of resources to the facility, including mitigation measures and the services of an infection control consultant, or even deploying the Pennsylvania National Guard to assist with staffing. Pennsylvania cannot force facilities to accept these services, she pointed out, but some refuse out of fear of receiving citations. “[O]ur top priority,” Levine said, “is halting COVID-19, not issuing citations.”
Her decisions on health restrictions and closures to combat the pandemic created controversy in the state, but much of the criticism also took aim at Levine identifying openly as transgender. Her selection as the first openly transgender official to be confirmed by the Senate has been targeted by conservative groups as a political gesture by President Biden. Tom Fitton, president of the conservative legal group Judicial Watch, posted on Facebook: “Biden gang playing quota politics with public health service.”
In her remarks to the Senate committee, however, Levine calmly noted that her appointment by Gov. Wolf was confirmed unanimously and that she was approved twice more on a bipartisan basis to be Secretary of Health. She met with nearly all of the senators personally. Her confirmation by the senate Republicans was particularly meaningful, she told NBC Out. “[They] judged me strictly on my professional qualifications.”
Social media has made much of Levine’s transgender identification, both pro and con. The Twitterverse, predictably, is packed with anti-Levine and anti-LGBTQ+ rants. But Levine’s rise has energized the LGBTQ+ community, who hail it as a breakthrough. Scout, the single-named executive director of the National LGBT Cancer Network, said, “The fact that she is trans is an inspiration for the many of us who have never had a role model this senior before.” Levine herself is determined to be a “beacon” in representing the LGBTQ+ community in her latest role at the corps: “Diversity makes us stronger,” she said.
“What people don’t understand, they fear,” Levine, who is a frequent public speaker, has said. “The more we can educate people and show that we’re productive members of the community—with families, lives, careers—that helps people understand us better.” That includes education of medical professionals. “We need to do a better job educating medical students about LGBT issues and transgender medicine,” she told NBC Out. She may need to start with the members of Congress. At Levine’s confirmation hearing to serve as Assistant Secretary for Health, Sen. Rand Paul, for instance, compared transgender surgery to “genital mutilation.”
HHS Secretary Becerra called Levine’s appointment as the first openly transgender four-star officer “a giant step forward toward equality as a nation.” US Surgeon General VADM Vivek Murthy, MD, MBA, said her appointment represents “an important step towards a more inclusive future and her service will undoubtedly advance the US Public Health Service Commissioned Corps’ mission to protect, promote, and advance the health and safety of our nation.”
Levine told the Senate committee, “There is still so much more to do.”
“We each come to public service in our own unique way,” ADM Rachel Levine, MD, Assistant Secretary for Health at the US Department of Health and Human Services (HHS), told the Senate Health, Education, Labor and Pensions Committee at her confirmation hearing in February 2021.
In her case, unique and history-making.

However, Kengor claimed, the “partisan press” would protect Wolf and Levine: “Levine is a liberal darling as the nation’s first (and arguably highest-ranking) transgender public official.”
At the February 2021 federal confirmation hearing, Levine was pressed on data discrepancies in Pennsylvania’s public reports on nursing home coronavirus deaths and cases. Sen. Susan Collins (R-ME) cited Spotlight PA reporting that found weekly reports released by the state health department were consistently missing data for more than 100 of the 693 nursing homes. Levine, in response, pointed to lags in the state’s electronic death reporting system and to slow uploads. Pennsylvania health officials also referred to a state law that prohibits the release of disease records by state or local authorities.
In a June 2020 opinion article, Levine wrote that the Pennsylvania Health Department had followed Centers for Disease Control and Prevention (CDC) guidance, including limiting outside people from entering long-term care facilities. The Pennsylvania Health Department also sent thousands of shipments of personal protective equipment and conducted virtual inspections, including on-site inspections as warranted.
Despite those efforts, Levine said, “staff members who have dedicated their lives to caring for these vulnerable Pennsylvanians unknowingly contracted COVID-19 in their communities and carried it into these facilities.” She pointed out that residents who returned from hospitals had been isolated if they contracted COVID-19. Patients returning to nursing homes did not introduce COVID-19, Levine said, “because it was there that they first came into contact with the virus.” Moreover, those patients were isolated, just as they had been before they required hospital-level care, she added.
When a long-term care facility reports a case of COVID-19, Levine noted, the Pennsylvania Health Department considers it an outbreak and offers a variety of resources to the facility, including mitigation measures and the services of an infection control consultant, or even deploying the Pennsylvania National Guard to assist with staffing. Pennsylvania cannot force facilities to accept these services, she pointed out, but some refuse out of fear of receiving citations. “[O]ur top priority,” Levine said, “is halting COVID-19, not issuing citations.”
Her decisions on health restrictions and closures to combat the pandemic created controversy in the state, but much of the criticism also took aim at Levine identifying openly as transgender. Her selection as the first openly transgender official to be confirmed by the Senate has been targeted by conservative groups as a political gesture by President Biden. Tom Fitton, president of the conservative legal group Judicial Watch, posted on Facebook: “Biden gang playing quota politics with public health service.”
In her remarks to the Senate committee, however, Levine calmly noted that her appointment by Gov. Wolf was confirmed unanimously and that she was approved twice more on a bipartisan basis to be Secretary of Health. She met with nearly all of the senators personally. Her confirmation by the senate Republicans was particularly meaningful, she told NBC Out. “[They] judged me strictly on my professional qualifications.”
Social media has made much of Levine’s transgender identification, both pro and con. The Twitterverse, predictably, is packed with anti-Levine and anti-LGBTQ+ rants. But Levine’s rise has energized the LGBTQ+ community, who hail it as a breakthrough. Scout, the single-named executive director of the National LGBT Cancer Network, said, “The fact that she is trans is an inspiration for the many of us who have never had a role model this senior before.” Levine herself is determined to be a “beacon” in representing the LGBTQ+ community in her latest role at the corps: “Diversity makes us stronger,” she said.
“What people don’t understand, they fear,” Levine, who is a frequent public speaker, has said. “The more we can educate people and show that we’re productive members of the community—with families, lives, careers—that helps people understand us better.” That includes education of medical professionals. “We need to do a better job educating medical students about LGBT issues and transgender medicine,” she told NBC Out. She may need to start with the members of Congress. At Levine’s confirmation hearing to serve as Assistant Secretary for Health, Sen. Rand Paul, for instance, compared transgender surgery to “genital mutilation.”
HHS Secretary Becerra called Levine’s appointment as the first openly transgender four-star officer “a giant step forward toward equality as a nation.” US Surgeon General VADM Vivek Murthy, MD, MBA, said her appointment represents “an important step towards a more inclusive future and her service will undoubtedly advance the US Public Health Service Commissioned Corps’ mission to protect, promote, and advance the health and safety of our nation.”
Levine told the Senate committee, “There is still so much more to do.”
“We each come to public service in our own unique way,” ADM Rachel Levine, MD, Assistant Secretary for Health at the US Department of Health and Human Services (HHS), told the Senate Health, Education, Labor and Pensions Committee at her confirmation hearing in February 2021.
In her case, unique and history-making. Levine was confirmed on Tuesday as the first-ever openly transgender—and firstwoman—four-star admiral in the history of the US Public Health Service Commissioned Corps. She is also the first openly transgender four-star officer and the first openly transgender person to be confirmed by the Senate. In fact, she is the nation’s highest-ranking openly transgender official—the first such across any of the eight uniformed services.
All those firsts aside, in her confirmation hearing remarks, ADM. Levine said, “At its core, my career has been about helping people live healthy lives.” She began her career at Mt. Sinai Medical Center in New York, in pediatric and adolescent medicine, focusing on mental and physical health. Moving to the Penn State College of Medicine, ADM Levine was a professor of pediatrics and psychiatry and vice-chair for clinical affairs for the Department of Pediatrics. At Penn State, she initiated the Division of Adolescent Medicine for the care of complex teens with medical and psychological problems. As chief of the Division of Adolescent Medicine and Eating Disorders at Penn State Hershey Medical Center, she also founded an eating disorders program, offering multidisciplinary treatment for children, adolescents, and adults.
In 2015, Pennsylvania Governor Tom Wolf nominated ADM Levine to be Physician General of the Commonwealth of Pennsylvania and she was confirmed unanimously by the state senate. In 2018, she was named Pennsylvania’s Secretary of Health. In these roles, she tackled the state’s massive opioid misuse and overdose crisis. She focused on opioid stewardship, developed continuing medical education programs, and established prescribing guidelines and a “robust” prescription drug monitoring program. She traveled extensively throughout small communities, doing public events with local officials and residents to talk about opioid abuse. The efforts began, slowly, to pay off. In 2015, 3,383 people died of drug overdose in Pennsylvania, a 23% increase from 2014. By 2018, 65% of drug overdose deaths involved opioids, but the total number of deaths fell to 2,866.
One of her most significant accomplishments as Physician General, Levine said, was to issue the first-ever statewide standing order for distribution of the anti-overdose drug naloxone, allowing law enforcement to carry the drug and Pennsylvania citizens to buy itover the counter. According to the Pennsylvania Opioid Data Dashboard, between January 1, 2018, and October 9, 2021, 62,954 doses of naloxone were administered by EMS.
In another of Levine’s projects, the Pennsylvania Rural Health Model, the goal was to move rural hospitals from fee-for-service models to global budget payments, which she said, “aligned incentives for providers to deliver value-based care and for rural hospitals to transform their care to better meet community health needs.”
Working in tandem with HHS, Levine’s teams also set up a maternal mortality review committee “to better understand and respond to the causes of maternal deaths,” and worked to improve childhood immunization rates.
“Of course, our focus changed dramatically last year,” Levine said, “and COVID-19 became my most urgent and primary focus.” She concentrated on three key priorities: containment with expansion of testing and contact tracing; mitigation with masks and distancing; and medical countermeasures, including monoclonal antibodies and vaccines. To carry out the strategies, she oversaw a health equity task force, which included community stakeholders such as the Black Coalition Against COVID-19, the Latino Connection, and a faith-based program that allowed people to get tested at their places of worship.
When lesbian, gay, bisexual, transgender, queer; lesbian, gay, bisexual, transgender, queer (LGBTQ+) advocates charged that states were not collecting data early in the pandemic on sexual orientation or gender identity, in another historic move, Levine announced in March 2020 that Pennsylvania would begin collecting demographic data on the coronavirus, making it the first state in the country to do so.
Levine has garnered praise from many sources. “This is a proud moment for us,” HHS Secretary Xavier Becerra said in a statement, calling her a “cherished and critical partner in our work to build a healthier America.” Alphonso David, then president of the Human Rights Campaign, said in a statement that Levine’s nomination to be the HHS Assistant Secretary for Health represented “real change” in the government’s approach to the coronavirus and LGBTQ+ health issues. Levine “led Pennsylvania’s public health response to the COVID-19 pandemic superbly,” he said.
She has also triggered a significant amount of outrage in conservative quarters. She was routinely castigated for her early actions in the pandemic. Writing for The American Spectator in May 2020, Paul Kengor, a former UPMC researcher, said UPMC’s overall handling of the virus was “impressive and inspired confidence.” However, tracking the data on fatalities, he said, he found the disproportionate number of deaths in nursing homes “alarming and strange.” Citing an investigative article in the Bucks County Courier Times, he blamed Pennsylvania officials—including Levine—for guidelines that directed licensed long-term care facilities to continue admitting new patients, including those discharged from hospitals back to nursing homes.

Tiny worms sniff out early-stage pancreatic cancer
Research shows Caenorhabditis elegans are attracted to the odor certain chemicals give off – a behavior known as attractive chemotaxis – and early evidence indicates these scents may include human cancer cell secretions, cancer tissues, and urine from patients with colorectal, gastric, and breast cancers.
According to the recent analysis, published in Oncotarget, these small worms may be hot on the trail of pancreatic cancer–related compounds too. The researchers found that C. elegans were significantly more attracted to patients with early-stage pancreatic cancer versus healthy controls.
There is a huge need for research like this that explores strategies to detect pancreatic cancer early, but it’s far too soon to tell how, or if, this particular approach will be clinically relevant, according to Neeha Zaidi, MD, assistant professor of oncology and a medical oncologist specializing in pancreatic cancer at John Hopkins Medicine, Baltimore, who was not involved in the current analysis.
Right now, few diagnostic markers exist for identifying pancreatic ductal adenocarcinomas (PDACs), which account for 90% of pancreatic cancers. PDACs remain one of the deadliest cancers, with a 5-year survival rate of 9%.
A combination of surgical resection and chemotherapy is the only curative treatment, and just 20% of patients are eligible, Dr. Zaidi said. The majority are identified after the disease has metastasized.
However, patients’ 5-year survival rate improves markedly – as high as 85% – if the condition is caught sooner.
In the current study, the researchers first exposed C. elegans to the urine of 83 patients from cancer centers across Japan who had various stages of pancreatic cancer before and after undergoing surgical resection. Using an assay, which takes 30 minutes and 50-100 nematodes per test, C. elegans showed significantly higher chemotaxis toward preoperative urine, compared with postoperative urine.
In a second, closed-labeled arm, the nematodes were exposed to the urine of 28 randomized participants – 11 of whom had early-stage pancreatic cancer (0 or IA), plus 17 healthy volunteers. In this instance as well, C. elegans showed significantly higher chemotaxis in patients with early-stage pancreatic cancer, compared with healthy volunteers (P = .034).
According to the authors, C. elegans “had a higher sensitivity for detecting early pancreatic cancer compared to existing diagnostic markers.” And while this strategy needs to be further validated, they believe early detection of pancreatic cancer using C. elegans “can certainly be expected in the near future.”
The study aligns with previous research, showing that wild-type C. elegans are sensitive to scent and that these critters can smell cancer. Other studies have also found that sniffer canines can detect volatile organic compounds – including biomarkers of certain cancers – in the urine and breath of cancer patients. But training an adequate number of these canines for the clinic isn’t feasible, while C. elegans are far more compact and affordable.
According to Dr. Zaidi, a scent test using C. elegans “seems pretty feasible” and cost effective, but whether this approach will “change our care has yet to be determined.”
The authors, for instance, don’t specify how the scent test will be used, though Dr. Zaidi suspects it would be most relevant for following patients with a higher risk of pancreatic cancer. Alternatively, it could be used as a screening test, but that’s a massive undertaking and “this is way too early to tell if it’s going to be helpful to use this test on a broad scale,” Dr. Zaidi said.
To validate the approach, researchers would also need to know what exactly the C. elegans are smelling and to test it in a much larger number of patients, Dr. Zaidi said. The mere 11 patients with cancer in the blinded portion of the study are not sufficient to draw any major conclusions.
The study also claims a high sensitivity, but what about specificity, Dr. Zaidi said. In other words, are there a lot of false positives?
In addition, a deeper look at the participants shows the two groups – early PDAC and healthy volunteers – were not adequately balanced. The median age of the diseased patients was 70, and the healthy volunteers was 39.
“This is a big difference,” Eithne Costello, PhD, professor of molecular oncology at Liverpool (England) University, said in an interview. “It [also] appears the controls are all of one sex (either all male or all female), while the cancer group is mixed.”
The authors attributed these shortcomings to the small population they had to work with: There simply aren’t many patients whose pancreatic cancer is detected early. Dr. Zaidi agreed that patients with pancreatic cancer stage 0 or IA are extremely difficult to come by.
Even still, researchers need to understand the mechanisms behind this approach and see it work in a much larger group of patients, Dr. Zaidi said.
The study was supported in part by a Grant-in-Aid for Scientific Research from the Ministry of Education, Culture, Sports, Science, and Technology. The authors reported institutional endowments received from Hirotsu Bio Science, Kinshu-kai Medical, IDEA Consultants, Ono Pharmaceutical, and others. Two coauthors are employees of Hirotsu Bio Science.
