Revival of the aspiration vs chest tube debate for PSP
Thoracic Oncology and Chest Procedures Network
Pleural Disease Section
Considerable heterogeneity exists in the management of primary spontaneous primary spontaneous pneumothorax (PSP). American and European guidelines have been grappling with this question for decades: What is the best way to manage PSP? A 2023 randomized, controlled trial (Marx et al. AJRCCM) sought to answer this.
The study recruited 379 adults aged 18 to 55 years between 2009 and 2015, with complete and first PSP in 31 French hospitals. One hundred eighty-nine patients initially received simple aspiration and 190 received chest tube drainage. The aspiration device was removed if a chest radiograph (CXR) following 30 minutes of aspiration showed lung apposition, with suction repeated up to one time with incomplete re-expansion. The chest tubes were large-bore (16-F or 20-F) and removed 72 hours postprocedure if the CXR showed complete lung re-expansion.
Simple aspiration was statistically inferior to chest tube drainage (29% vs 18%). However, first-line simple aspiration resulted in shorter length of stay, less subcutaneous emphysema, site infection, pain, and one-year recurrence.
Since most first-time PSP occurs in younger, healthier adults, simple aspiration could still be considered as it is better tolerated than large-bore chest tubes. However, with more frequent use of small-bore (≤14-F) catheters, ambulatory drainage could also be a suitable option in carefully selected patients. Additionally, inpatient chest tubes do not need to remain in place for 72 hours, as was this study’s protocol. Society guidelines will need to weigh in on the latest high-quality evidence available for final recommendations.

AI applications in pediatric pulmonary, sleep, and critical care medicine
Airways Disorders Network
Pediatric Chest Medicine Section
Artificial intelligence (AI) refers to the science and engineering of making intelligent machines that mimic human cognitive functions, such as learning and problem solving.1 Asthma exacerbations in young children were detected reliably by AI-aided stethoscope alone.2 Inhaler use has been successfully tracked using active and passive patient input to cloud-based dashboards.3 Asthma specialists can potentially use this knowledge to intervene in real time or more frequent intervals than the current episodic care.
Sleep trackers using commercial-grade sensors can provide useful information about sleep hygiene, sleep duration, and nocturnal awakenings. An increasing number of “wearables” and “nearables” that utilize AI algorithms to evaluate sleep duration and quality are FDA approved. AI-based scoring of polysomnography data can improve the efficiency of a sleep laboratory. Big data analysis of CPAP compliance in children led to identification of actionable items that can be targeted to improve patient outcomes.4
The use of AI models in clinical decision support can result in fewer false alerts and missed patients due to increased model accuracy. Additionally, large language model tools can automatically generate comprehensive progress notes incorporating relevant electronic medical records data, thereby reducing physician charting time.
These case uses highlight the potential to improve workflow efficiency and clinical outcomes in pediatric pulmonary and critical care by incorporating AI tools in medical decision-making and management.

Mechanical power: A missing piece in lung-protective ventilation?
Critical Care Network
Mechanical Ventilation and Airways Management Section
The ARDSNet trial demonstrated the importance of low tidal volume ventilatsion in patients with ARDS, and we have learned to monitor parameters such as plateau pressure and driving pressure (DP) to ensure lung-protective ventilation. What role does the higher respiratory rate play? There is growing evidence that respiratory rate may play an important part in the pathogenesis of ventilator-induced lung injury (VILI) and the dynamic effect of both rate and static pressures needs to be evaluated.
The concept of mechanical power (MP) was formalized in 2016 by Gattinoni, et al and defined as the product of respiratory rate and total inflation energy gained per breath.1 Calculations have been developed for both volume-controlled and pressure-controlled ventilation, including elements such as respiratory rate and PEEP. Studies have shown that increased MP is associated with ICU and hospital mortality, even at low tidal volumes.2 The use of MP remains limited in clinical practice due to its dynamic nature and difficulty of calculating in routine clinical practice but may be a feasible addition to the continuous monitoring outputs on a ventilator. Additional prospective studies are also needed to define the optimal threshold of MP and to compare monitoring strategies using MP vs DP.

Major takeaways from the seventh world symposium on PH
Pulmonary Vascular and Cardiovascular Network
Pulmonary Vascular Disease Section
The core definition of pulmonary hypertension (PH) remains a mean pulmonary arterial pressure (mPAP) > 20 mm Hg, with precapillary PH defined by a pulmonary arterial wedge pressure (PCWP) ≤ 15 mm Hg and pulmonary vascular resistance (PVR) > 2 Wood units (WU), similar to the 2022 European guidelines.1,2 There was recognition of uncertainty in patients with borderline PAWP (12-18 mm Hg) for postcapillary PH.
It’s crucial to phenotype patients, especially those with valvular heart disease, hypertrophic cardiomyopathy, or amyloid cardiomyopathy, and to be cautious when using PAH medications for this PH group.3
Group 3 PH is often underrecognized and associated with poor outcomes, so screening in clinically stable patients is recommended using a multimodal assessment before hemodynamic evaluation. Inhaled treprostinil is recommended for PH associated with interstitial lung disease (ILD). However, the PERFECT trial on PH therapy in COPD was stopped due to safety concerns, highlighting the need for careful evaluation in chronic lung disease (CLD) patients.4 For risk stratification, further emphasis was made on cardiac imaging and hemodynamic data.
Significant progress was made in understanding four key pathways, including bone morphogenetic protein (BMP)/activin signaling. A treatment algorithm based on risk stratification was reinforced, recommending initial triple therapy with parenteral prostacyclin analogs for high-risk patients.5 Follow-up reassessment may include adding an activin-signaling inhibitor for all risk groups except low risk, as well as oral or inhaled prostacyclin for intermediate-low risk groups.

Extending exercise testing using telehealth monitoring in patients with ILD
Diffuse Lung Disease and Lung Transplant Network
Pulmonary Physiology and Rehabilitation Section
The COVID-19 pandemic revolutionized the use of monitoring equipment in general and oxygen saturation monitoring devices as pulse oximeters in specific. The increasing adoption of activity trackers is geared toward promoting an active lifestyle through real-time feedback and continuous monitoring. Patients with interstitial lung diseases (ILDs) suffer from different symptoms; one of the most disabling is dyspnea. Primarily associated with oxygen desaturation, it initiates a detrimental cycle of decreased physical activity, ultimately compromising the overall quality of life.
The use of activity trackers has shown to enhance exercise capacity among ILD and sarcoidosis patients.1
Implementing continuous monitor activity by activity trackers coupled with continuous oxygen saturation can provide a comprehensive tool to follow up with ILD patients efficiently and accurately based on established use of a six-minute walk test (6MWT) and desaturation screen. Combined 6MWT and desaturation screens remain the principal predictors to assess the disease progression and treatment response in a variety of lung diseases, mainly pulmonary hypertension and ILD and serve as a prognostic indicator of those patients.2 One of the test limitations is that the distance walked in six minutes reflects fluctuations in quality of life.3 Also, the test measures submaximal exercise performance rather than maximal exercise capacity.4
Associations have been found in that the amplitude of oxygen desaturation at the end of exercise was poorly reproducible in 6MWT in idiopathic Interstitial pneumonia.5
Considering the mentioned limitations of the classic 6MWT, an alternative approach involves extended desaturation screen using telehealth and involving different activity levels. However, further validation across a diverse spectrum of ILDs remains essential.

Weight Loss Surgery, Obesity Drugs Achieve Similar Results but Have Different Safety Profiles
PHILADELPHIA — according to a meta-analysis comparing the efficacy and safety of the different treatment options.
However, tirzepatide, a long-acting glucose-dependent insulinotropic polypeptide (GIP) receptor agonist and glucagon-like peptide 1 receptor agonist (GLP-1 RA), produces comparable weight loss and has a favorable safety profile, reported principal investigator Jena Velji-Ibrahim, MD, MSc, from Prisma Health–Upstate/University of South Carolina School of Medicine in Greenville.
In addition, there was “no significant difference in percentage total body weight loss between tirzepatide when comparing it to one-anastomosis gastric bypass (OAGB), as well as laparoscopic sleeve gastrectomy,” she said.
All 11 interventions studied exerted weight loss effects, and side-effect profiles were also deemed largely favorable, particularly for endoscopic interventions, she added.
“When we compare bariatric surgery to bariatric endoscopy, endoscopic sleeve gastroplasty and transpyloric shuttle offer a minimally invasive alternative with good weight loss outcomes and fewer adverse events,” she said.
Velji-Ibrahim presented the findings at the annual meeting of the American College of Gastroenterology (ACG).
Comparing Weight Loss Interventions
Many of the studies comparing weight loss interventions to date have been limited by relatively small sample sizes, observational designs, and inconsistent results. This prompted Velji-Ibrahim and her colleagues to conduct what they believe to be the first-of-its-kind meta-analysis on this topic.
They began by conducting a systematic search of the literature to identify randomized controlled trials (RCTs) that compared the efficacy of Food and Drug Administration–approved bariatric surgeries, bariatric endoscopies, and medications — against each other or with placebo — in adults with a body mass index of 25-45, with or without concurrent type 2 diabetes.
A network meta-analysis was then performed to assess the various interventions’ impact on percentage total weight loss and side-effect profiles. P-scores were calculated to rank the treatments and identify the preferred interventions. The duration of therapy was 52 weeks.
In total, 34 eligible RCTs with 15,660 patients were included. Overall, the RCTs analyzed 11 weight loss treatments, including bariatric surgeries (four studies), bariatric endoscopies (three studies), and medications (four studies).
Specifically, the bariatric surgeries included RYGB, laparoscopic sleeve gastrectomy, OAGB, and laparoscopic adjustable gastric banding; bariatric endoscopies included endoscopic sleeve gastroplasty, transpyloric shuttle, and intragastric balloon; and medications included tirzepatide, semaglutide, and liraglutide.
Although all interventions were associated with reductions in percentage total weight loss compared with placebo, RYGB led to the greatest reductions (19.29%) and was ranked as the first preferred treatment (97% probability). It was followed in the rankings by OAGB, tirzepatide 15 mg, laparoscopic sleeve gastrectomy, and semaglutide 2.4 mg.
Tirzepatide 15 mg had a slightly lower percentage total weight loss (15.18%) but a favorable safety profile. There was no significant difference in percentage total weight loss between tirzepatide 15 mg and OAGB (mean difference, 2.97%) or laparoscopic sleeve gastrectomy (mean difference, 0.43%).
There was also no significant difference in percentage total weight loss between semaglutide 2.4 mg, compared with endoscopic sleeve gastroplasty and transpyloric shuttle.
Endoscopic sleeve, transpyloric shuttle, and intragastric balloon all resulted in weight loss > 5%.
When compared with bariatric surgery, “endoscopic interventions had a better side-effect profile, with no increased odds of mortality and intensive care needs,” Velji-Ibrahim said.
When it came to the medications, “the most common side effects were gastrointestinal in nature, which included nausea, vomiting, diarrhea, and constipation,” she said.
Combining, Rather Than Comparing, Therapies
Following the presentation, session co-moderator Shivangi T. Kothari, MD, assistant professor of medicine and associate director of endoscopy at the University of Rochester Medical Center in New York, shared her thoughts of what the future of obesity management research might look like.
It’s not just going to be about percentage total weight loss, she said, but about how well the effect is sustained following the intervention.
And we might move “away from comparing one modality to another” and instead study combination therapies, “which would be ideal,” said Kothari.
This was the focus of another meta-analysis presented at ACG 2024, in which Nihal Ijaz I. Khan, MD, and colleagues compared the efficacy of endoscopic bariatric treatment alone vs its combined use with GLP-1 RAs.
The researchers identified three retrospective studies with 266 patients, of whom 143 underwent endoscopic bariatric treatment alone (either endoscopic sleeve gastroplasty or intragastric balloon) and 123 had it combined with GLP-1 RAs, specifically liraglutide.
They reported that superior absolute weight loss was achieved in the group of patients receiving GLP-1 RAs in combination with endoscopic bariatric treatment. The standardized mean difference in body weight loss at treatment follow-up was 0.61 (P <.01).
“Further studies are required to evaluate the safety and adverse events comparing these two treatment modalities and to discover differences between comparing the two endoscopic options to various GLP-1 receptor agonists,” Khan noted.
Neither study had specific funding. Velji-Ibrahim and Khan reported no relevant financial relationships. Kothari reported serving as a consultant for Boston Scientific and Olympus, as well as serving as an advisory committee/board member for Castle Biosciences.

FROM ACG 2024
Cannabis Often Used as a Substitute for Traditional Medications
Nearly two thirds of patients with rheumatic conditions switched to medical cannabis from medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids, with the substitution being associated with greater self-reported improvement in symptoms than nonsubstitution.
METHODOLOGY:
- Researchers conducted a secondary analysis of a cross-sectional survey to investigate the prevalence of switching to medical cannabis from traditional medications in patients with rheumatic conditions from the United States and Canada.
- The survey included questions on current and past medical cannabis use, sociodemographic characteristics, medication taken and substituted, substance use, and patient-reported outcomes.
- Of the 1727 patients who completed the survey, 763 patients (mean age, 59 years; 84.1% women) reported current use of cannabis and were included in this analysis.
- Participants were asked if they had substituted any medications with medical cannabis and were sub-grouped accordingly.
- They also reported any changes in symptoms after initiating cannabis, the current and anticipated duration of medical cannabis use, methods of ingestion, cannabinoid content, and frequency of use.
TAKEAWAY:
- Overall, 62.5% reported substituting medical cannabis for certain medications, including NSAIDs (54.7%), opioids (48.6%), sleep aids (29.6%), muscle relaxants (25.2%), benzodiazepines (15.5%), and gabapentinoids (10.5%).
- The most common reasons given for substituting medical cannabis were fewer side effects (39%), better symptom control (27%), and fewer adverse effects (12%).
- Participants who substituted medical cannabis reported significant improvements in symptoms such as pain, sleep, joint stiffness, muscle spasms, and inflammation, and in overall health, compared with those who did not substitute it for medications.
- The substitution group was more likely to use inhalation methods (smoking and vaporizing) than the nonsubstitution group; they also used medical cannabis more frequently and preferred products containing delta-9-tetrahydrocannabinol.
IN PRACTICE:
“The changing legal status of cannabis has allowed a greater openness with more people willing to try cannabis for symptom relief. These encouraging results of medication reduction and favorable effect of [medical cannabis] require confirmation with more rigorous methods. At this time, survey information may be seen as a signal for effect, rather than sound evidence that could be applicable to those with musculoskeletal complaints in general,” the authors wrote.
SOURCE:
The study was led by Kevin F. Boehnke, PhD, University of Michigan Medical School, Ann Arbor, and was published online in ACR Open Rheumatology.
LIMITATIONS:
The cross-sectional nature of the study limited the determination of causality between medical cannabis use and symptom improvement. Moreover, the anonymous and self-reported nature of the survey at a single timepoint may have introduced recall bias. The sample predominantly consisted of older, White females, which may have limited the generalizability of the findings to other demographic groups.
DISCLOSURES:
Some authors received grant support from the National Institute on Drug Abuse and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Some others received payments, honoraria, grant funding, consulting fees, and travel support, and reported other ties with pharmaceutical companies and other institutions.

Weight Loss Drugs Don’t Reduce Oocyte Retrieval
The use of glucagon-like peptide 1 (GLP-1) agonists within a year had no apparent effect on the number of oocytes retrieved in controlled ovarian hyperstimulation (COH), based on data from 73 patients in a multicenter study.
Obesity rates continue to rise in women of reproductive age and many women are using GLP-1 agonists for weight loss, but data on the effect of these drugs on fertility treatments are lacking, said Victoria K. Lazarov, MD, of Icahn School of Medicine at Mount Sinai, New York City, in an abstract presented at the American Society for Reproductive Medicine (ASRM) 2024 scientific congress.
Clinical opinions regarding the use, duration, and discontinuation of GLP-1 agonists during fertility treatments are variable given the limited research, Lazarov noted in her abstract. More data are needed to standardize patient counseling.
Lazarov and colleagues reviewed data from patients who sought treatment at clinics affiliated with a national fertility network from 2005 to 2023 who also utilized a GLP-1 agonist within 1 year of COH.
The study population included 73 adult women; participants were divided into six groups based on the number of days without GLP-1 agonist use prior to retrieval (0-14, 15-30, 31-60, 61-90, 91-180, and 181-365 days). The primary outcome was oocyte yield following COH.
Overall, the mean oocyte yields were not significantly different across the six timing groups (14.4, 16.2, 16.8, 7.7, 13.8, and 15, respectively; P = .40).
In a secondary subgroup analysis, the researchers found an inverse relationship between oocyte yield and timing of GLP-1 agonist discontinuation in patients with body mass index (BMI) > 35. However, no changes in oocyte yield were observed in patients with BMIs in the normal or overweight range. Neither duration of GLP-1 agonist use or indication for use had a significant effect on oocyte yield across exposure group.
The findings were limited by several factors, including the relatively small study population, especially the small number of patients with obesity. “Additional investigation is needed to clarify potential effects of GLP-1 agonist use on aspiration risk during oocyte retrieval and embryo creation outcomes,” the researchers wrote in their abstract.
However, the results suggest that most women who use GLP-1 agonists experience no significant effects on oocyte retrieval and embryo creation, and that GLP-1 agonists may have a role in improving oocyte yield for obese patients, the researchers concluded.
Larger Studies Needed for Real Reassurance
“Infertility patients who are overweight have lower chances for conception and higher risks of pregnancy complications,” Mark Trolice, MD, professor at the University of Central Florida College of Medicine, Orlando, and founder/director of The IVF Center, Winter Park, Florida, said in an interview.
The use of GLP-1 agonists has dramatically increased given the medication’s effectiveness for weight loss, as well as its use to manage diabetes, but the use of GLP-1 agonists in pregnancy is not well known and current recommendations advise discontinuation of the medication for 6-8 weeks prior to conception, said Trolice, who was not involved in the study.
GLP-1 agonist use is associated with lowered blood glucose levels, Trolice said. “Additionally, the medication can delay gastric emptying and suppress appetite, both of which assist in weight management.”
The current study examined whether there was a difference in oocyte retrieval number in women based on days of discontinuation of GLP-1 agonists prior to the procedure, Trolice told this news organization. “Given the drug’s mechanism of action, there is no apparent biological influence that would impact oocyte yield. Consequently, the study outcome is not unexpected.”
The study purports potential reassurance that GLP-1 exposure, regardless of the duration of discontinuation, has no impact on egg retrieval number, said Trolice. However, “Based on the size of the study, to accept the findings as definitive would risk a type II statistical error.”
Two key areas for additional research are urgently needed, Trolice said, namely, the duration of time to discontinue GLP-1 agonists, if at all, prior to conception, and the discontinuation interval, if at all, prior to anesthesia to avoid airway complications.
The American Society of Anesthesiologists advises patients on daily dosing to consider holding GLP-1 agonists on the day of a procedure or surgery, and those on weekly dosing should consider discontinuing the medication 1 week before the procedure or surgery, Trolice noted.
The study received no outside funding. The researchers had no financial conflicts to disclose. Trolice had no financial conflicts to disclose and serves on the editorial advisory board of OB/GYN News.

GLP-1 agonist use is associated with lowered blood glucose levels, Trolice said. “Additionally, the medication can delay gastric emptying and suppress appetite, both of which assist in weight management.”
The current study examined whether there was a difference in oocyte retrieval number in women based on days of discontinuation of GLP-1 agonists prior to the procedure, Trolice told this news organization. “Given the drug’s mechanism of action, there is no apparent biological influence that would impact oocyte yield. Consequently, the study outcome is not unexpected.”
The study purports potential reassurance that GLP-1 exposure, regardless of the duration of discontinuation, has no impact on egg retrieval number, said Trolice. However, “Based on the size of the study, to accept the findings as definitive would risk a type II statistical error.”
Two key areas for additional research are urgently needed, Trolice said, namely, the duration of time to discontinue GLP-1 agonists, if at all, prior to conception, and the discontinuation interval, if at all, prior to anesthesia to avoid airway complications.
The American Society of Anesthesiologists advises patients on daily dosing to consider holding GLP-1 agonists on the day of a procedure or surgery, and those on weekly dosing should consider discontinuing the medication 1 week before the procedure or surgery, Trolice noted.
The study received no outside funding. The researchers had no financial conflicts to disclose. Trolice had no financial conflicts to disclose and serves on the editorial advisory board of OB/GYN News.

The use of glucagon-like peptide 1 (GLP-1) agonists within a year had no apparent effect on the number of oocytes retrieved in controlled ovarian hyperstimulation (COH), based on data from 73 patients in a multicenter study.
Obesity rates continue to rise in women of reproductive age and many women are using GLP-1 agonists for weight loss, but data on the effect of these drugs on fertility treatments are lacking, said Victoria K. Lazarov, MD, of Icahn School of Medicine at Mount Sinai, New York City, in an abstract presented at the American Society for Reproductive Medicine (ASRM) 2024 scientific congress.
Clinical opinions regarding the use, duration, and discontinuation of GLP-1 agonists during fertility treatments are variable given the limited research, Lazarov noted in her abstract. More data are needed to standardize patient counseling.
Lazarov and colleagues reviewed data from patients who sought treatment at clinics affiliated with a national fertility network from 2005 to 2023 who also utilized a GLP-1 agonist within 1 year of COH.
The study population included 73 adult women; participants were divided into six groups based on the number of days without GLP-1 agonist use prior to retrieval (0-14, 15-30, 31-60, 61-90, 91-180, and 181-365 days). The primary outcome was oocyte yield following COH.
Overall, the mean oocyte yields were not significantly different across the six timing groups (14.4, 16.2, 16.8, 7.7, 13.8, and 15, respectively; P = .40).
In a secondary subgroup analysis, the researchers found an inverse relationship between oocyte yield and timing of GLP-1 agonist discontinuation in patients with body mass index (BMI) > 35. However, no changes in oocyte yield were observed in patients with BMIs in the normal or overweight range. Neither duration of GLP-1 agonist use or indication for use had a significant effect on oocyte yield across exposure group.
The findings were limited by several factors, including the relatively small study population, especially the small number of patients with obesity. “Additional investigation is needed to clarify potential effects of GLP-1 agonist use on aspiration risk during oocyte retrieval and embryo creation outcomes,” the researchers wrote in their abstract.
However, the results suggest that most women who use GLP-1 agonists experience no significant effects on oocyte retrieval and embryo creation, and that GLP-1 agonists may have a role in improving oocyte yield for obese patients, the researchers concluded.
Larger Studies Needed for Real Reassurance

Primary Care Physicians Underutilize Nonantibiotic Prophylaxis for Recurrent UTIs
While primary care physicians are generally comfortable prescribing vaginal estrogen therapy for recurrent urinary tract infections (UTIs), other nonantibiotic prophylactic options remain significantly underutilized, according to new research that highlights a crucial gap in antibiotic stewardship practices among primary care physicians.
UTIs are the most common bacterial infection in women of all ages, and an estimated 30%-40% of women will experience reinfection within 6 months. Recurrent UTI is typically defined as two or more infections within 6 months or a greater number of infections within a year, according to the American Academy of Family Physicians.
Antibiotics are the first line of defense in preventing and treating recurrent UTIs, but repeated and prolonged use could lead to antibiotic resistance.
Researchers at the University of North Carolina surveyed 40 primary care physicians at one academic medical center and found that 96% of primary care physicians prescribe vaginal estrogen therapy for recurrent UTI prevention, with 58% doing so “often.” Estrogen deficiency and urinary retention are strong contributors to infection.
However, 78% of physicians surveyed said they had never prescribed methenamine hippurate, and 85% said they had never prescribed D-mannose.
Physicians with specialized training in menopausal care felt more at ease prescribing vaginal estrogen therapy to patients with complex medical histories, such as those with a family history of breast cancer or endometrial cancer. This suggests that enhanced education could play a vital role in increasing comfort levels among general practitioners, said Lauren Tholemeier, MD, a urogynecology fellow at the University of North Carolina at Chapel Hill.
“Primary care physicians are the front line of managing patients with recurrent UTI,” said Tholemeier.
“There’s an opportunity for further education on, and even awareness of, methenamine hippurate and D-mannose as an option that has data behind it and can be included as a tool” for patient care, she said.
Indeed, physicians who saw six or more recurrent patients with UTI each month were more likely to prescribe methenamine hippurate, the study found, suggesting that familiarity with recurrent UTI cases can lead to greater confidence in employing alternative prophylactic strategies.
Tholemeier presented her research at the American Urogynecologic Society’s PFD Week in Washington, DC.
Expanding physician knowledge and utilization of all available nonantibiotic therapies can help them better care for patients who don’t necessarily have access to a subspecialist, Tholemeier said.
According to the American Urogynecologic Society’s best practice guidelines, there is limited evidence supporting routine use of D-mannose to prevent recurrent UTI. Methenamine hippurate, however, may be effective for short-term UTI prevention, according to the group.
By broadening the use of vaginal estrogen therapy, methenamine hippurate, and D-mannose, primary care physicians can help reduce reliance on antibiotics for recurrent UTI prevention — a practice that may contribute to growing antibiotic resistance, said Tholemeier.
“The end goal isn’t going to be to say that we should never prescribe antibiotics for UTI infection,” said Tholemeier, adding that, in some cases, physicians can consider using these other medications in conjunction with antibiotics.
“But it’s knowing they [clinicians] have some other options in their toolbox,” she said.

Maternal BMI and Eating Disorders Tied to Mental Health in Kids
TOPLINE:
Children of mothers who had obesity or eating disorders before or during pregnancy may face higher risks for neurodevelopmental and psychiatric disorders.
METHODOLOGY:
- Researchers conducted a population-based cohort study to investigate the association of maternal eating disorders and high prepregnancy body mass index (BMI) with psychiatric disorder and neurodevelopmental diagnoses in offspring.
- They used Finnish national registers to assess all live births from 2004 through 2014, with follow-up until 2021.
- Data of 392,098 mothers (mean age, 30.15 years) and 649,956 offspring (48.86% girls) were included.
- Maternal eating disorders and prepregnancy BMI were the main exposures, with 1.60% of mothers having a history of eating disorders; 5.89% were underweight and 53.13% had obesity.
- Diagnoses of children were identified and grouped by ICD-10 codes of mental, behavioral, and neurodevelopmental disorders, mood disorders, anxiety disorders, sleep disorders, attention-deficit/hyperactivity disorder, and conduct disorders, among several others.
TAKEAWAY:
- From birth until 7-17 years of age, 16.43% of offspring were diagnosed with a neurodevelopmental or psychiatric disorder.
- Maternal eating disorders were associated with psychiatric disorders in the offspring, with the largest effect sizes observed for sleep disorders (hazard ratio [HR], 2.36) and social functioning and tic disorders (HR, 2.18; P < .001 for both).
- The offspring of mothers with severe prepregnancy obesity had a more than twofold increased risk for intellectual disabilities (HR, 2.04; 95% CI, 1.83-2.28); being underweight before pregnancy was also linked to many psychiatric disorders in offspring.
- The occurrence of adverse birth outcomes along with maternal eating disorders or high BMI further increased the risk for neurodevelopmental and psychiatric disorders in the offspring.
IN PRACTICE:
“The findings underline the risk of offspring mental illness associated with maternal eating disorders and prepregnancy BMI and suggest the need to consider these exposures clinically to help prevent offspring mental illness,” the authors wrote.
SOURCE:
This study was led by Ida A.K. Nilsson, PhD, of the Department of Molecular Medicine and Surgery at the Karolinska Institutet in Stockholm, Sweden, and was published online in JAMA Network Open.
LIMITATIONS:
A limitation of the study was the relatively short follow-up time, which restricted the inclusion of late-onset psychiatric disorder diagnoses, such as schizophrenia spectrum disorders. Paternal data and genetic information, which may have influenced the interpretation of the data, were not available. Another potential bias was that mothers with eating disorders may have been more perceptive to their child’s eating behavior, leading to greater access to care and diagnosis for these children.
DISCLOSURES:
This work was supported by the Swedish Research Council, the regional agreement on medical training and clinical research between Region Stockholm and the Karolinska Institutet, the Swedish Brain Foundation, and other sources. The authors declared no conflicts of interest.
