Pediatric stroke thrombectomy study sheds light on off-label procedure
based on data from a retrospective, multicenter study of 73 patients.
Children with high scores on the Pediatric National Institutes of Health Stroke Scale (PedNIHSS) or large-vessel occlusion in the anterior or posterior circulation are at increased risk for morbidity and mortality, but the safety of thrombectomy in children has not been well studied. Several randomized trials have showed its safety and efficacy in adults, wrote Peter Sporns, MD, of the Institute of Clinical Radiology at Universitätsklinikum Muenster (Germany), and colleagues.
In a study published in JAMA Neurology, Dr. Sporns and coauthors reviewed data from pediatric patients aged younger than 18 years who underwent endovascular recanalization between Jan. 1, 2000, and Dec. 31, 2018, at 25 stroke centers in Europe and 2 in the United States.
The primary outcome was change in the PedNIHSS scores and the endovascular recanalization involved “a combination of techniques using distal thrombaspiration and/or clot retrievers,” the researchers wrote.
Neurologic outcomes improved from a median PedNIHSS score of 14.0 at hospital admission to 4.0 at day 7. The average time from stroke onset to hospital admission was 3 hours, and the median time from stroke onset to recanalization was 4 hours.
“The rapidity of recanalization across the large number of centers in the Save ChildS study is a commendable achievement, establishing feasibility for acute pediatric stroke treatment within the short window of time for embolectomy at centers prepared for this event,” wrote Christine Fox, MD, of the University of California, San Francisco, and Nomazulu Dlamini, MBBS, PhD, of the Hospital for Sick Children, Toronto, in an accompanying editorial.
In addition, the median modified Rankin Scale score was 1.0 at discharge and at 6 and 24 months, and the median Pediatric Stroke Outcome Measure score was 1.0 at discharge and 0.5 at 6 and 24 months.
The median age of the patients was 11 years, and approximately half were boys (51%). A total of 63 children (86%) were treated for anterior circulation occlusion, and 10 (14%) were treated for posterior circulation occlusion; (22%) received concomitant intravenous thrombolysis.
Transient vasospasm was the only observed periprocedural complication, seen in four patients, and all cases resolved without clinical sequelae. One patient with a history of a heart anomaly died of cardiac arrest after recanalization. No vascular complications were reported, and the proportion of symptomatic intracerebral hemorrhage events was 1.37 per 100 observations, compared with 2.79 in a meta-analysis of adult studies.
The main limitation of the study was its retrospective design, as well as the absence of a control group, the researchers noted. However, the results “may support clinicians’ practice of off-label thrombectomy in childhood stroke in the absence of high-level evidence.”
The editorial authors emphasized that safety concerns remain despite the relatively low level of complications observed in the current study. “The safety of thrombectomy in children with suspected focal cerebral arteriopathy or bilateral arteriopathies is a particular concern because of the potential to further injure an acutely inflamed or chronically diseased vessel,” they wrote.
“We should be cautious about the interpretation of long-term outcome measures in the Save ChildS study,” Dr. Fox and Dr. Dlamini added, noting that additional multicenter studies are needed “to advance our knowledge of pediatric stroke and inform best practices.”

Preop IV dexamethasone conveys relief after total knee surgery
Patients given a single preoperative dose of intravenous dexamethasone had significantly less pain after total knee arthroplasty than did those given a placebo in a randomized controlled study of 100 adults.
“Corticosteroids were introduced several years ago for relieving postoperative pain in total joint replacement but, unfortunately, are not widely used due to surgeons’ concerns and the limited supporting evidence,” wrote Nattapol Tammachote, MD, of Thammasat University, Khlong Luang, Pathumthani, Thailand, and colleagues.
In a study published in the Journal of Arthroplasty, the researchers randomized 50 adults undergoing unilateral total knee surgery to a preoperative IV dexamethasone dose of 0.15 mg/kg diluted with normal saline or saline placebo. Patients, who were aged 50-85 years, were assessed every 3 hours after surgery, up to 48 hours; the primary outcomes were pain level, using the visual analog pain scale (VAS), and morphine use.
Overall, patients in the treatment group reported significant reductions on the VAS in mean pain scores of 11 points at rest and 15 points with knee movement. No significant differences in morphine use were noted between groups overall or at 12-hour intervals post-surgery.
In the first 24-48 hours after surgery dexamethasone was associated with a significantly lower rate of nausea and vomiting vs. placebo (58% vs. 84%), and a lower average C-reactive protein level (89 mg/L vs. 167 mg/L) at 48 hours after surgery. Hospital stays averaged 3 days for both groups, and no wound infections were reported.
Scores on tests of knee function using the modified Western Ontario and McMaster University Osteoarthritis Index scores and range of motion of the knee at three months were similar between the groups.
The study findings were limited by several factors, including the small sample size and use of multimodal pain control that may have impacted morphine use, a lack of data on hyperglycemia, and variation in doses of ketorolac given to patients in both groups, the researchers noted.
The results nevertheless support the potential of preoperative dexamethasone as “a promising approach in postoperative pain management and may be suitable for patients with contraindication to multimodal pain regimens,” they concluded.
The researchers reported no financial conflicts.

Short-term statin use linked to risk of skin and soft tissue infections
according to a sequence symmetry analysis of prescription claims over a 10-year period reported in the British Journal of Clinical Pharmacology.
In the study, statin use for as little as 91 days was linked with elevated risks of SSTIs and diabetes. However, the increased risk of infection was seen in individuals who did and did not develop diabetes, wrote Humphrey Ko, of the school of pharmacy and biomedical sciences, Curtin University, Perth, Australia, and colleagues.
The current literature on the impact of statins on SSTIs is conflicted, they noted. Previous research shows that statins “may reduce the risk of community-acquired [Staphylococcus aureus] bacteremia and exert antibacterial effects against S. aureus,” and therefore may have potential for reducing SSTI risk “or evolve into promising novel treatments for SSTIs,” the researchers said; they noted, however, that other data show that statins may induce new-onset diabetes.
They examined prescription claims (for statins, antidiabetic medications, and antistaphylococcal antibiotics) from 2001 to 2011 from the Australian Department of Veterans’ Affairs that included more than 228,000 veterans, war widows, and widowers. Prescriptions for antistaphylococcal antibiotics were used as a marker of SSTIs.
Overall, statins were significantly associated with an increased risk of SSTIs at 91 days (adjusted sequence ratio, 1.40). The risk of SSTIs from statin use was similar at 182 (ASR, 1.41) and 365 days (ASR, 1.40). In this case, the ASRs represent the incidence rate ratios of prescribing antibiotics in statin-exposed versus statin-nonexposed person-time.
Statins were associated with a significantly increased risk of new onset diabetes, but the SSTI risk was not significantly different between statin users with and without diabetes. Statin users who did not have diabetes had significant SSTI risks at 91, 182, and 365 days (ASR, 1.39, 1.41, and 1.37, respectively) and statin users with diabetes had similarly significant risks of SSTIs (ASR,1.43, 1.42, and 1.49, respectively).
In addition, socioeconomic status appeared to have no significant effect on the relationship between statin use, SSTIs, and diabetes, the researchers noted.
The findings were limited by several factors including the inability to account for patient compliance in taking the medications, a lack of dosage data to determine the impact of dosage on outcomes, and potential confounding by the presence of diabetes, they said. However, the results suggest that “it would seem prudent for clinicians to monitor blood glucose levels of statin users who are predisposed to diabetes, and be mindful of possible increased SSTI risks in such patients,” they concluded. Statins, they added, “may increase SSTI risk via direct or indirect mechanisms.”
More clinical trials are needed to confirm the mechanisms, and “to ascertain the effect of statins on gut dysbiosis, impaired bile acid metabolism, vitamin D levels, and cholesterol inhibition on skin function,” they wrote.
The study was supported in part by the Australian Government Research Training Program Scholarship, the Curtin Health Innovation Research Institute Biosciences Research Precinct Core Facility, and the School of Pharmacy and Biomedical Sciences (Curtin University). The researchers had no financial conflicts to disclose.

Preop pain perceptions drive outcomes after knee surgery
Adult athletes who underwent knee surgery and had higher levels of preoperative pain catastrophizing were significantly less likely to return to preinjury activity, based on data from 101 individuals.
Pain is highly subjective, and pain perception can play a role in postsurgical outcomes, but the relationships among preoperative pain perception and short-term outcomes including returning to sports have not been well-studied, wrote Joshua S. Everhart, MD, of The Ohio State University Wexner Medical Center, Columbus, and colleagues.
In a study published in the Journal of Science and Medicine in Sport, the researchers assessed 101 adult athletes who underwent knee surgery at a single center. The average age of the patients was 33 years, and 49 were women.
Pain perception and coping were assessed via the McGill Pain questionnaire (SF-MPQ), Pain Catastrophizing Scale (PCS), Pain Coping Measure (PCM), and the brief COPE subscales of acceptance, denial, positive reframing, and use of instrumental support.
Patients who were severe pain catastrophizers (defined as scores greater than 36 on the Pain Catastrophizing Scale) had increased odds of not returning to a similar level of sport (OR 11.3).
Higher scores on the brief COPE subscale of “use of instrumental support” (instruments designed to help patients cope with pain) had a protective effect on returning to preinjury activity (OR 0.72 per point increase). However, higher COPE-denial scores were significantly associated with lower odds of improvement in kinesiophobia (OR 0.43).
Patients with greater levels of problem-focused coping had significantly greater improvement in International Knee Documentation Committee (IKDC) scores, as did patients who were older and more active.
“Specific coping strategies appear to moderate the effect of pain perceptions on postoperative outcomes, with some coping strategies being protective and others being harmful,” the researchers said.
The findings were limited by several factors including the use of multiple comparisons, the inability to assess the impact of pain perception after knee rehabilitation independent of surgery, and the small number of some uncommon procedures, the researchers noted.
However, the results suggest that “recognition of pain perception and coping styles early on in treatment may help sports medicine providers identify patients at risk for an unsatisfactory subjective outcome,” they concluded.
The researchers had no financial conflicts to disclose.

Pain perception and coping were assessed via the McGill Pain questionnaire (SF-MPQ), Pain Catastrophizing Scale (PCS), Pain Coping Measure (PCM), and the brief COPE subscales of acceptance, denial, positive reframing, and use of instrumental support.
Patients who were severe pain catastrophizers (defined as scores greater than 36 on the Pain Catastrophizing Scale) had increased odds of not returning to a similar level of sport (OR 11.3).
Higher scores on the brief COPE subscale of “use of instrumental support” (instruments designed to help patients cope with pain) had a protective effect on returning to preinjury activity (OR 0.72 per point increase). However, higher COPE-denial scores were significantly associated with lower odds of improvement in kinesiophobia (OR 0.43).
Patients with greater levels of problem-focused coping had significantly greater improvement in International Knee Documentation Committee (IKDC) scores, as did patients who were older and more active.
“Specific coping strategies appear to moderate the effect of pain perceptions on postoperative outcomes, with some coping strategies being protective and others being harmful,” the researchers said.
The findings were limited by several factors including the use of multiple comparisons, the inability to assess the impact of pain perception after knee rehabilitation independent of surgery, and the small number of some uncommon procedures, the researchers noted.
However, the results suggest that “recognition of pain perception and coping styles early on in treatment may help sports medicine providers identify patients at risk for an unsatisfactory subjective outcome,” they concluded.
The researchers had no financial conflicts to disclose.

White AAV patients post highest mortality rates
Age-adjusted mortality from antineutrophil cytoplasmic autoantibody–associated vasculitides (AAV) in the United States declined by nearly 2% each year between 1999 and 2017, based on data from the Centers for Disease Control and Prevention.
Significant morbidity and mortality are associated with untreated AAV, wrote Alexander W. Steinberg, MD, of Saint Joseph Hospital, Denver, Colo., and colleagues.
“Although population data from the United Kingdom have shown decreased AAV-related mortality during the past 20 years, it is unknown whether this pattern has occurred in the United States,” they wrote.
In a study published in Annals of Internal Medicine, the researchers identified 11,316 AAV-related deaths from 1999 to 2017 in the CDC data.
Overall, age-adjusted mortality was 1.86 per 1,000,000 persons, with highest rates among non-Hispanic whites, men, and residents of the Midwest. Mortality from AAV declined by an average of 1.6% in each year of the study period, and changes in subgroups stratified by gender, race, and geographic region were similar.
Mortality increased with age and was highest among individuals aged 75-84 years, but a significant decline in mortality occurred among individuals aged 65-74 years. “The decrease in overall mortality and mortality among persons aged 65 to 74 years may reflect increased longevity due to improved treatment of AAV and common comorbid conditions,” the researchers said.
“Surprisingly, the authors found much lower age-adjusted mortality rates for non-Hispanic black persons (0.77) and moderately lower mortality rates for Hispanic persons (1.57) than for non-Hispanic white persons (2.03),” wrote John R. Stone, MD, PhD, of Creighton University, Omaha, Neb., in an accompanying editorial.
“Suppose the mortality rate differences reported by Steinberg and colleagues are statistically significant, accurately represent death certificate diagnoses, and match people’s racial/ethnic self-identification. The data then show neither that the vasculitides actually have lower mortality rates in blacks or Hispanics compared with whites, nor that the diseases are indeed less frequent in blacks and Hispanics,” he said. “Rather, these differences probably signify how social inequities, social structural violence, and inferior health care access adversely influence diagnosis of rare diseases and promote health inequity,” Dr. Stone added. The findings suggest that clinicians should remain alert to AAV in some ethnic groups to improve diagnostic accuracy, he said.
“Moreover, improved AAV diagnosis in such groups is key to recruiting participants for research investigating whether therapies should differ among populations,” he emphasized.
The study findings were limited by possible under- or overreporting of AAV on death certificates, but they were strengthened by the large sample size, the researchers noted. “We hope that the mortality patterns presented here can be used to direct future research on the driving forces behind these trends,” they said.

Clinician burnout can impact quality of care
Burnout among health care professionals has been associated with lower quality of care, but the effect may be smaller than it seems, based on data from a meta-analysis of more than 200,000 clinicians.
Previous studies have reported associations between burnout and lower quality of care, but a standardized approach to analyze bias in the studies is lacking, wrote Daniel S. Tawfik, MD, of Stanford (Calif.) University and colleagues.
In a study published in the Annals of Internal Medicine, the researchers identified 123 publications from 1994 to 2019 with 142 study populations that included 241,553 health care providers.
Emotional exhaustion was the primary predictor for lower quality of care in 75 study populations, and overall burnout and depersonalization were the primary predictors for 56 and 11 study populations, respectively.
In an analysis of 114 unique burnout-quality combinations, 58 showed effects of burnout related to poor-quality care, 6 showed burnout related to high-quality care, and 50 showed no significant effect. Approximately one-third (33%) of the burnout-quality combinations were reported at least three times. In a review of the 46 burnout-quality combinations with primary effect sizes, 24 showed a significant effect of burnout on poor quality of care, 1 showed a significant effect of burnout on high quality of care, and 21 showed no significant effect.
The researchers also tested study bias using the Ioannidis test and found “an excess of observed versus predicted statistically significant studies (73% observed vs. 62%).”
The findings were limited by several factors, including the use of many cross-sectional, observational studies that could not show causality, the researchers noted. However, the results suggest several implications for future research including the need to consider exaggerated effects and reduce bias.
“Although the effect sizes in the published literature are modestly strong, our finding of excess significance implies that the true magnitude may be smaller than reported, and the studies that attempted to lower the risk of bias demonstrate fewer significant associations than the full evidence base,” the researchers noted.
“Whether curtailing burnout improves quality of care, or whether improving quality of care reduces burnout, is not yet known, and adequately powered and designed randomized trials will be indispensable in answering these questions,” they concluded.
The study was supported by the Stanford Maternal and Child Health Research Institute. Dr. Tawfik disclosed grants from Stanford Maternal and Child Health Research Institute during the study period.

The current meta-analysis is consistent with previous research, but offers nothing new on the relationship between clinician burnout and quality of care, wrote Carolyn S. Dewa, MPH, PhD, Karen Nieuwenhuijsen, PhD, and Jeffrey S. Hoch, PhD, in an accompanying editorial.
Some of the concerns they expressed included variability in the methods used to measure provider burnout, as well as variability in measuring and defining medical error. They suggested that the researchers could have conducted a subgroup analysis based on error definition. “Such analyses might shed light on the types of errors associated with burnout and suggest directions for the design of robust psychometric studies about the error metrics,” they wrote.
The editorialists also expressed concerns about the heterogeneity of the studies included in the review and the potential for confounding. Finally, they noted that the use of observational studies in a meta-analysis can be challenging because “the assessment of observational studies is not straightforward.” They added that knowing the limitations of the studies is important in allowing readers to be confident in the estimates from any meta-analyses.
“Considering the limitations of the available literature, prior reviews, and Tawfik and colleagues’ current meta-analysis, we conclude that higher burnout is associated with lower quality, but we are left without clear answers about the magnitude or clinical significance of the relationship,” they wrote (Ann Intern Med. 2019 Oct 8. doi: 10.7326/M19-2760).

FDA approves trifarotene for treating acne
The Food and Drug Administration has approved trifarotene cream 0.005% for the treatment of acne vulgaris. The product is manufactured by Galderma under the brand name Aklief.
The approval was based on data from a pair of phase 3, randomized trials including 2,420 patients aged 9 years and older. The trials evaluated the effectiveness of the cream in a once-daily topical dose for facial and truncal acne at 12 weeks. Patients showed a significant reduction in the number of inflammatory lesions as early as 2 weeks on the face (including forehead cheeks, nose, and chin) and as early as 4 weeks on the trunk (including back, chest, and shoulders), compared with a control cream. The most common treatment-emergent adverse events were pain, dryness, discoloration, or rash at the site of application. Some patients also reported sunburn.
The complete study findings were published in the June issue of the Journal of the American Academy of Dermatology.
The studies, funded by Galderma, “showed that once-daily trifarotene cream appears effective and safe, with manageable local tolerability, for the treatment for facial and truncal acne,” wrote lead author Jerry Tan, MD, of the University of Western Ontario, London, and colleagues. “The studies provide substantial evidence to support use of this new topical retinoid in facial and truncal acne,” the researchers wrote.
Trifarotene is designed to target the retinoic acid receptor gamma, the most common retinoic acid receptor in the skin, and is the first new retinoid to be approved by the FDA in approximately 2 decades, according to a press release from Galderma.
The product is expected to be available in the United States in November 2019 in a 45-g pump.

Lifetime indoor tanning raises risk of cutaneous squamous cell carcinoma
Women who accumulated more indoor tanning sessions over time significantly increased their risk for squamous cell cancer over women who never engaged in indoor tanning, based on data from 159,419 women.
Previous research has examined associations between indoor tanning and cutaneous melanoma, but an association between indoor tanning and squamous cell carcinoma (SCC) has not been well studied, wrote Simon Lergenmuller, MSc, of the University of Oslo, and colleagues.
In a prospective cohort study published in JAMA Dermatology, the researchers surveyed 159,419 women from the Norwegian Women and Cancer study. Of these, 95,552 women (69%) reported ever use of indoor tanning. The average age at study inclusion was 50 years. During an average of 17 years’ follow-up, 597 women developed SCC.
Overall, the risk of SCC increased with increasing numbers of indoor tanning sessions. The adjusted hazard ratio for most tanning sessions versus no tanning sessions was 1.83. “The association between cumulative exposure to indoor tanning and SCC risk was the same regardless of duration of use and age at initiation,” the researchers wrote.
The risk of SCC was significantly higher both among women with 10 years or less of tanning bed use and among those with more than 10 years of use, compared with never users (HRs, 1.41 and 1.43, respectively). Similarly, researchers found a significantly higher risk of SCC among women who started indoor tanning at age 30 years or older and those who started younger than 30 years, compared with never users (HRs, 1.36 and HR, 1.51, respectively).
No significant association appeared between age at initiation of indoor tanning and age at the time of SCC diagnosis.
The study findings were limited by several factors including the variation in UV radiation among tanning devices, the lack of data on men, and the retrospective collection of UV exposure data that likely led to some misclassification, the researchers noted.
However, the results were strengthened by the large sample size and support the association between increased exposure to indoor tanning and increased risk of SCC, they wrote. “Avoidance of indoor tanning may help prevent not only melanoma but also SCC, and our results support the development of policies that regulate indoor tanning.”
The study was supported by the Institute of Basic Medical Sciences, University of Oslo, and the Norwegian Cancer Society. The researchers had no financial conflicts to disclose.

“There is a saying that ‘when prevention works, nothing happens,’ ” wrote Boris D. Lushniak, MD, in an accompanying editorial. Dermatology plays an important role in public health, most notably skin cancer prevention, and the specialty’s efforts to educate the public and raise awareness about skin cancer and its causes are paying off, in combination with government initiatives to reduce exposure to UV radiation. The current study adds to the data on risk factors for skin cancer, and is distinctive in its focus on artificial sources of UV radiation, specifically indoor tanning sources. The relationship between indoor tanning and basal cell carcinoma or squamous cell carcinoma has not been well studied, “so this study fills an important gap,” he noted.
Research on indoor tanning and other skin cancer risk factors can help expand skin cancer prevention efforts and support goals such as the Healthy People 2020 goal of “reducing the proportion of adolescents in grades 9-12 who report using artificial sources of UV light for tanning, and reducing the proportion of adults aged 18 years or older who report using artificial sources of UV light for tanning,” he wrote.
The first-ever Surgeon General’s Call to Action to Prevent Skin Cancer, released in 2014, made skin cancer prevention a priority and offered specific strategies including providing more sun protection in outdoor settings, educating the public about UV exposure, promoting polices to help prevent skin cancer, reducing harm from indoor tanning, and increasing the collection of data related to skin cancer prevention.
The strategies seem to be working, Dr. Lushniak wrote. Based on data from the 2015 Youth Risk Behavior Surveillance System, a significant linear decrease in the use of indoor tanning devices by youth occurred between 2009 and 2015. “Oftentimes we do not appreciate or celebrate the successes of prevention. ... Let’s keep on track on that bold and noble mission of preventing skin cancer,” he added (JAMA Dermatol. 2019 Oct 2. doi: 10.1001/jamadermatol.2019.2680).

The relationship between indoor tanning and basal cell carcinoma or squamous cell carcinoma has not been well studied, “so this study fills an important gap,” he noted.
Research on indoor tanning and other skin cancer risk factors can help expand skin cancer prevention efforts and support goals such as the Healthy People 2020 goal of “reducing the proportion of adolescents in grades 9-12 who report using artificial sources of UV light for tanning, and reducing the proportion of adults aged 18 years or older who report using artificial sources of UV light for tanning,” he wrote.
The first-ever Surgeon General’s Call to Action to Prevent Skin Cancer, released in 2014, made skin cancer prevention a priority and offered specific strategies including providing more sun protection in outdoor settings, educating the public about UV exposure, promoting polices to help prevent skin cancer, reducing harm from indoor tanning, and increasing the collection of data related to skin cancer prevention.
The strategies seem to be working, Dr. Lushniak wrote. Based on data from the 2015 Youth Risk Behavior Surveillance System, a significant linear decrease in the use of indoor tanning devices by youth occurred between 2009 and 2015. “Oftentimes we do not appreciate or celebrate the successes of prevention. ... Let’s keep on track on that bold and noble mission of preventing skin cancer,” he added (JAMA Dermatol. 2019 Oct 2. doi: 10.1001/jamadermatol.2019.2680).

Women who accumulated more indoor tanning sessions over time significantly increased their risk for squamous cell cancer over women who never engaged in indoor tanning, based on data from 159,419 women.
Previous research has examined associations between indoor tanning and cutaneous melanoma, but an association between indoor tanning and squamous cell carcinoma (SCC) has not been well studied, wrote Simon Lergenmuller, MSc, of the University of Oslo, and colleagues.
In a prospective cohort study published in JAMA Dermatology, the researchers surveyed 159,419 women from the Norwegian Women and Cancer study. Of these, 95,552 women (69%) reported ever use of indoor tanning. The average age at study inclusion was 50 years. During an average of 17 years’ follow-up, 597 women developed SCC.
Overall, the risk of SCC increased with increasing numbers of indoor tanning sessions. The adjusted hazard ratio for most tanning sessions versus no tanning sessions was 1.83. “The association between cumulative exposure to indoor tanning and SCC risk was the same regardless of duration of use and age at initiation,” the researchers wrote.
The risk of SCC was significantly higher both among women with 10 years or less of tanning bed use and among those with more than 10 years of use, compared with never users (HRs, 1.41 and 1.43, respectively). Similarly, researchers found a significantly higher risk of SCC among women who started indoor tanning at age 30 years or older and those who started younger than 30 years, compared with never users (HRs, 1.36 and HR, 1.51, respectively).
No significant association appeared between age at initiation of indoor tanning and age at the time of SCC diagnosis.
The study findings were limited by several factors including the variation in UV radiation among tanning devices, the lack of data on men, and the retrospective collection of UV exposure data that likely led to some misclassification, the researchers noted.
However, the results were strengthened by the large sample size and support the association between increased exposure to indoor tanning and increased risk of SCC, they wrote. “Avoidance of indoor tanning may help prevent not only melanoma but also SCC, and our results support the development of policies that regulate indoor tanning.”
The study was supported by the Institute of Basic Medical Sciences, University of Oslo, and the Norwegian Cancer Society. The researchers had no financial conflicts to disclose.

Supine sleep in late pregnancy may promote low birth weight
Data from previous studies suggest that impaired uteroplacental flow can affect fetal growth, wrote Ngaire H. Anderson, PhD, of the University of Auckland, N.Z., and colleagues.
“The initial going-to-sleep position is the sleep position that women maintain for the longest duration throughout the night; therefore, going-to-sleep position is likely to have the greatest impact on blood flow to the developing fetus,” they said.
In a study published in JAMA Network Open, the researchers interviewed women with ongoing pregnancies at 28 weeks’ gestation or later to determine their sleeping positions. The mean age of the participants was 30 years. Of the 1,760 women, 3% reported that they usually slept supine during the past 1-4 weeks.
The adjusted mean birth weight was 3,410 g among supine sleepers and 3,554 g among nonsupine sleepers. The primary outcome was an adjusted mean difference in birth weight between infants of supine sleepers and nonsupine sleepers, which was a statistically significant 144 g (P = .009).
The study findings were limited by several factors including the small number of women who were reported supine sleepers, as well as the reliance on self-reports of sleep position, the researchers said.
However, women who had going-to-sleep data for the previous night and the previous month suggest that most women are consistent in their going-to-sleep position, they noted. “It is also biologically plausible that the association of decreased maternal blood flow on birth size with supine maternal position is cumulative over time,” but the researchers were not able to investigate how the duration of supine sleeping might further affect birth weight.
Although it might make additional studies more difficult, a public health campaign to encourage pregnant women to sleep on their side during the third trimester is a safe and easy opportunity to potentially optimize birth weight, they added.
The study was important because of the limited number of high-quality studies on the effects of maternal sleep on perinatal outcomes, Martina Badell, MD of Emory University in Atlanta said in an interview.
“The overall findings suggested a possible small increased risk of small-for-gestational-age babies with supine maternal sleeping, however, the absolute gram difference of 144 grams at term may not be clinically relevant,” she said. In addition, the relatively small number of women who reported supine sleep in late pregnancy suggests that broad public health campaigns or recommendations may not be indicated at this time.
“Also, the percentage of women who are supine sleepers at term is only approximately 3%, and this study didn’t assess reasons for supine sleeping in this small subset of women,” she said. “Further research is needed to assess whether there are specific maternal factors associated with supine sleeping, such as GI symptoms or respiratory difficulties, which could contribute to smaller fetal size rather than the sleep position itself.”
The study was supported by a Trans-Tasman Research Funding Grant by Cure Kids and Red Nose Australia. Six coauthors reported receiving numerous grants from a variety of organizations. Dr. Anderson and the remaining coauthors had no financial conflicts to disclose. Dr. Badell had no relevant financial disclosures.

Lefamulin found noninferior to moxifloxacin for bacterial pneumonia
Persistent high rates of bacterial resistance to current treatments have created the need for more options, especially for the treatment of community-acquired bacterial pneumonia (CABP), which remains a leading cause of hospitalization and death in the United States, wrote Elizabeth Alexander, MD, of Nabriva Therapeutics in King of Prussia, Penn., and colleagues. Lefamulin, “the first pleuromutilin antibiotic approved for intravenous and oral use in humans,” has demonstrated activity against many CABP-causing pathogens, including some not susceptible to other classes of antimicrobials, they noted.
Findings of Lefamulin Evaluation Against Pneumonia 2 (LEAP2) were published in JAMA. In this study, the researchers randomized 370 patients to 600 mg of oral lefamulin every 12 hours for 5 days and 368 patients to 400 mg of oral moxifloxacin every 24 hours for 7 days.
Early clinical response rates at 96 hours were 90.8% for both medications (difference of 0.1%). In addition, the rates of clinical response success were similar between the groups in both the modified intent-to-treat population (87.5% with lefamulin and 89.1% with moxifloxacin) and the clinically evaluable population (89.7% with lefamulin and 93.6% with moxifloxacin).
Gastrointestinal issues of diarrhea and nausea were the two most frequently reported treatment-emergent adverse events in both groups. Both conditions occurred more often in the lefamulin group, compared with the moxifloxacin group, but the differences were not significant (12.2% vs. 1.1% and 5.2% vs. 1.9%, respectively).
The study findings were limited by several factors including strict exclusion criteria that may limit the generalizability of the results, as well as a lack of testing for viral copathogens, low recovery of resistant pathogens, and possible misclassification of patient ethnicity, the researchers noted.
However, the results were strengthened by the randomized design, inclusion of patients with more severe CABP, and low rate of discontinuation, they said. The data support previous studies of lefamulin. Its lack of cross-resistance to other drug classes, coverage of typical and atypical CABP pathogens, and options for both oral and intravenous use suggest that it “may provide an alternative approach for the treatment of vulnerable patients,” the researchers said.
The study was supported by Nabriva Therapeutics. Dr. Alexander and several coauthors are employees of Nabriva Therapeutics and own stock in the company.

“The development and approval of a new antibiotic is a rare occurrence and a reason to celebrate” given the scientific, regulatory, and economic challenges to antibiotic development, wrote Preeti N. Malani, MD, in an accompanying editorial. Lefamulin in both oral and intravenous forms was approved by the Food and Drug Administration in August 2019 for the treatment of community-acquired bacterial pneumonia, Dr. Malani said.
Lefamulin will likely be an expensive option. According to a manufacturer press release, lefamulin may cost $205/day for intravenous treatment and $275/day for oral treatment. “This is severalfold more than moxifloxacin or levofloxacin, which are the most commonly prescribed fluoroquinolones for CABP [community-acquired bacterial pneumonia],” said Dr. Malani. However, the addition of lefamulin to the array of antibiotics is important because of the persistent burden of bacterial pneumonia as an indication for antibiotic use, Dr. Malani emphasized.
