Objectives: The purpose of this study was to examine the effects of COPD on in-hospital outcomes in TTS patients.

The impact of margins and re-resection in pediatric synovial sarcoma.

Introduction: Synovial sarcoma is one of the most common soft tissue sarcomas in children. Guidelines regarding the adequate extent of resection margins and the role of re-resection are lacking. We sought to evaluate the adequate resection margin and the role of re-resection in predicting outcomes in children with synovial sarcomas.

Improving United States HPV vaccination rates: Factors predictive of parental attitudes towards middle school entry requirements.

Although the human papillomavirus (HPV) vaccine is effective at preventing infection and certain types of cancer, uptake is suboptimal. HPV vaccine requirements for school entry are an underutilized strategy to increase HPV vaccine uptake among adolescents. The purpose of this study was to understand the factors that are predictive of parents' attitudes toward schools requiring the HPV vaccine for entry into middle school.

The association of payer type on genicular radiofrequency neurotomy treatment outcomes: Results of a cross-sectional study.

Background: Genicular radiofrequency neurotomy (GRFN) is an effective treatment for a subset of individuals with chronic knee pain. Previous studies demonstrate that Medicare and Medicaid beneficiaries report worse outcomes following various interventional procedures compared with commercially insured patients.

Objective: Evaluate the association of payer type on GRFN treatment outcomes.

Endogenous adenine is a potential driver of the cardiovascular-kidney-metabolic syndrome.

Mechanisms underlying the cardiovascular-kidney-metabolic (CKM) syndrome are unknown, although key small molecule metabolites may be involved. Bulk and spatial metabolomics identified adenine to be upregulated and specifically enriched in coronary blood vessels in hearts from patients with diabetes and left ventricular hypertrophy. Single nucleus gene expression studies revealed that endothelial methylthioadenosine phosphorylase (MTAP) was increased in human hearts with hypertrophic cardiomyopathy.

Methodological approaches in developing and implementing digital health interventions amongst underserved women.

Background: Minority populations are utilizing mobile health applications more frequently to access health information. One group that may benefit from using mHealth technology is underserved women, specifically those on community supervision.

Objective: Discuss methodological approaches for navigating digital health strategies to address underserved women's health disparities.

Disease and Non-Battle Injury in Deployed Military: A Systematic Review and Meta-analysis.

Introduction: Disease and non-battle injury (DNBI) has historically been the leading casualty type among service members in warfare and a leading health problem confronting military personnel, resulting in significant loss of manpower. Studies show a significant increase in disease burden for DNBI when compared to combat-related injuries. Understanding the causes of and trends in DNBI may help guide efforts to develop preventive measures and help increase medical readiness and resiliency.

Events in context-The HED framework for the study of brain, experience and behavior.

The brain is a complex dynamic system whose current state is inextricably coupled to awareness of past, current, and anticipated future threats and opportunities that continually affect awareness and behavioral goals and decisions. Brain activity is driven on multiple time scales by an ever-evolving flow of sensory, proprioceptive, and idiothetic experience. Neuroimaging experiments seek to isolate and focus on some aspect of these complex dynamics to better understand how human experience, cognition, behavior, and health are supported by brain activity.
