Leptin physiology and pathophysiology in energy homeostasis, immune function, neuroendocrine regulation and bone health.

Since its discovery and over the past thirty years, extensive research has significantly expanded our understanding of leptin and its diverse roles in human physiology, pathophysiology and therapeutics. A prototypical adipokine initially identified for its critical function in appetite regulation and energy homeostasis, leptin has been revealed to also exert profound effects on the hypothalamic-pituitary-gonadal, thyroid, adrenal and growth hormone axis, differentially between animals and humans, as well as in regulating immune function. Beyond these roles, leptin plays a pivotal role in significantly affecting bone health by promoting bone formation and regulating bone metabolism both directly and indirectly through its neuroendocrine actions.

Using machine learning to derive neurobiological subtypes of general psychopathology in late childhood.

Traditional mental health diagnoses rely on symptom-based classifications. Yet this approach can oversimplify clinical presentations as diagnoses often do not adequately map onto neurobiological features. Alternatively, our study used structural imaging data and a semisupervised machine learning technique, heterogeneity through discriminative analysis, to identify neurobiological subtypes in 9- to 10-year-olds with high psychopathology endorsements (n = 9,027).

Standard-of-Care Medication Withdrawal in Patients With Obstructive Hypertrophic Cardiomyopathy Receiving Aficamten in FOREST-HCM.

Background: Standard-of-care (SoC) medications for the treatment of obstructive hypertrophic cardiomyopathy (oHCM) are recommended as first-line therapy despite the lack of evidence from controlled clinical trials and well known off-target side effects.

Objectives: We describe the impact of SoC therapy downtitration and withdrawal in patients already receiving aficamten in FOREST-HCM (Follow-Up, Open-Label, Research Evaluation of Sustained Treatment with Aficamten in Hypertrophic Cardiomyopathy; NCT04848506).

Methods: Patients receiving SoC therapy (beta-blocker, nondihydropyridine calcium-channel blocker, and/or disopyramide) were eligible for protocol-guided SoC downtitration and withdrawal at the discretion of the investigator and after achieving a stable dose of aficamten for ≥4 weeks.

A machine learning framework to adjust for learning effects in medical device safety evaluation.

Objectives: Traditional methods for medical device post-market surveillance often fail to accurately account for operator learning effects, leading to biased assessments of device safety. These methods struggle with non-linearity, complex learning curves, and time-varying covariates, such as physician experience. To address these limitations, we sought to develop a machine learning (ML) framework to detect and adjust for operator learning effects.

Consensus Considerations and Good Practice Points for Use of Continuous Glucose Monitoring Systems in Hospital Settings.

Continuous glucose monitoring (CGM) systems provide frequent glucose measurements in interstitial fluid and have been used widely in ambulatory settings for diabetes management. During the coronavirus disease 2019 (COVID-19) pandemic, regulators in the U.S.

Outcomes of down-titration in patients with severe scalp alopecia areata initially treated with baricitinib 4-mg: Week 152 data from BRAVE-AA2.

Background: Baricitinib, an oral selective Janus kinase inhibitor, is approved to treat adults with severe alopecia areata (AA).

Objective: To report the week 152 efficacy results from the phase 3 trial BRAVE-AA2 down-titration substudy.

Methods: BRAVE-AA2 enrolled 546 adults with severe AA (Severity of Alopecia Tool [SALT] score ≥50).

Particulate Matter 2.5 Pollution Impact on Comorbid Cancer and Cardiovascular Disease Mortality in the U.S.

Background: Evidence regarding the effect of long-term exposure to particulate matter (PM) 2.5 and comorbid cancer and cardiovascular disease (CVD) mortality is limited.

Objectives: In this study, the author report the association between long-term exposure to PM 2.

The learning curve for robotic living donor right hepatectomy: Analysis of outcomes in 2 specialized centers.

Robotic surgery is an emerging minimally invasive option for living donor hepatectomy. Currently, there are no studies on the learning curve of robotic donor hepatectomy. Thus, we evaluated the learning curve for robotic donor right hepatectomy.

The COMPARE Study: Comparing Perioperative Outcomes of Oncologic Minimally Invasive Laparoscopic, Da Vinci Robotic, and Open Procedures: A Systematic Review and meta-analysis of The Evidence.

Objective: To assess 30-day outcomes of da Vinci robotic-assisted (dV-RAS) versus laparoscopic/thoracoscopic (lap/VATS) or open oncologic surgery.

Summary Background Data: Complex procedures in deep/narrow spaces especially benefit from dV-RAS. Prior procedure-specific comparisons are not generalizable.

Operational outcomes of community-to-academic emergency department patient transfers.

Background: Many patients require inter-hospital transfer (IHT) to tertiary Emergency Departments (EDs) to access specialty services. The purpose of this study is to determine operational outcomes for patients undergoing IHT to a tertiary academic ED, with an emphasis on timing and specialty consult utilization.

Methods: This study was a retrospective observational cohort study at a tertiary academic hospital from 10/1/21-9/30/22.

Anorectal Abscess.

Anorectal abscesses are a common colorectal emergency. The hallmark of treatment is obtaining source control while avoiding injury to the underlying sphincter complex. Understanding the anatomy of an anorectal abscess is critical to planning the appropriate drainage strategy and decreasing the risk of complex fistula formation.

Quality of Life and Psychosocial Outcomes Among Children With Cleft Differences.

Introduction Velopharyngeal insufficiency (VPI) and craniofacial differences can lead to diminished speech and swallowing function resulting in communication and social challenges throughout childhood. To monitor changes in patients' psychosocial health and velopharyngeal function, the Pediatric Symptom Checklist (PSC) and Velopharyngeal Insufficiency Effects on Life Outcomes (VELO) survey tools can be utilized. This study aimed to investigate the relationship between VPI quality-of-life outcomes and psychosocial disturbances through a comparative analysis of PSC and VELO parental surveys among children followed by a craniofacial team.

Association Between Neuromuscular Blocking Agents and Outcomes of Emergency Tracheal Intubation: A Secondary Analysis of Randomized Trials.

Study Objective: To examine the association between the neuromuscular blocking agent received (succinylcholine versus rocuronium) and the incidences of successful intubation on the first attempt and severe complications during tracheal intubation of critically ill adults in an emergency department (ED) or ICU.

Methods: We performed a secondary analysis of data from 2 multicenter randomized trials in critically ill adults undergoing tracheal intubation in an ED or ICU. Using a generalized linear mixed-effects model with prespecified baseline covariates, we examined the association between the neuromuscular blocking agent received (succinylcholine versus rocuronium) and the incidences of successful intubation on the first attempt (primary outcome) and severe complications during tracheal intubation (secondary outcome).

Access to a Patient Portal is Associated with a Higher Rate of Diabetic Eye Examination Completion.

Purpose: To evaluate factors associated with a higher completion rate of annual diabetic eye examinations.

Methods: This retrospective, cross-sectional study included patients diagnosed with diabetes mellitus (DM) who were aged 18-75 years and receiving primary care in a suburban integrated delivery network (IDN). Patient demographic, sociomedical, biometric characteristics, and Healthcare Effectiveness Data and Information Set (HEDIS) measures within the Comprehensive Diabetes Care bundle were extracted from the electronic health record (EHR) and analyzed by using multivariate logistic regression to assess factors associated with completion of an eye exam (retinal) performed during the study year.
