Latent autoimmune diabetes in adults (LADA) is a slowly progressing form of diabetes that develops in adulthood, characterized by autoimmune destruction of pancreatic β-cells and subsequent insulin deficiency, akin to type 1 diabetes (T1D). Due to its shared genetic, immunological, and metabolic features with both T1D and type 2 diabetes (T2D), LADA is frequently misdiagnosed and inappropriately treated as T2D. To address this, we developed the A.

Background: Prior studies suggest a poorer prognosis in men and Black people with multiple sclerosis (pwMS). The possibility that delays in evaluation or diagnosis could contribute to worse outcomes remains underexplored. Our objective is to see if men or Black pwMS have delays in being evaluated for and diagnosed with multiple sclerosis (MS).

The use of vasopressors during microsurgical reconstruction is debated. Their effect on the comorbid lower extremity (LE) wound population is unstudied. This study characterizes the impact of intraoperative vasopressor use in LE free tissue transfer (FTT) for limb salvage.

Current approaches used for pediatric liver transplant (LT) surveillance have diagnostic limitations. We used pleximmune™ immune reactivity index (IRI) and anti-HLA donor specific antibody (DSA) to predict the adequacy of immunosuppression (IS) relative to risk of acute cellular rejection (ACR) at 1-year post LT. This is a retrospective chart review of children who underwent LT between January 1, 2016, through December 31, 2020, and had at least one pleximmune measurement performed within 60-days of a liver biopsy.

Objective: Variations exist among surgeons in the treatment of recurrent lumbar disc herniation (LDH), generating major issues in decision-making models. The authors aimed to identify international nuances in surgical treatment patterns, highlight the differences in responses in each country group and different treatment trends across countries, and identify factors that influence surgical decisions.

Methods: An online survey with preformulated answers was submitted to 292 orthopedic surgeons and 223 neurosurgeons from 16 countries regarding 3 clinical vignettes (recurrence without low back pain, recurrence with severe low back pain, and recurrence with 2-level disc disease).

Introduction: Hispanics are over-represented in outdoor occupations; therefore they face an elevated risk of skin cancer. However, there is limited research examining these workers' self-risk perceptions and sun-protective behaviors. This study explores Hispanic outdoor workers' knowledge, attitudes, barriers, and facilitators for engaging in sun-protective behaviors to inform a culturally-tailored intervention.

Purpose: Cancer-related cognitive impairment (CRCI) adversely affects cancer survivors' academic, occupational, and psychosocial functioning. Analyzing the National Institutes of Health (NIH) portfolio of funded research provides insight into current efforts, trends, and gaps in CRCI research.

Methods: We queried the internal NIH iSearch database to identify awards focused on CRCI.

Sudden death in children and young adults, while uncommon, carries profound clinical and societal implications. Cardiac causes, particularly inherited arrhythmias and cardiomyopathies, account for most cases, though neurologic, toxicologic, traumatic, and infectious etiologies also contribute significantly. This review explores the epidemiology, classification, and pathophysiologic mechanisms of sudden death in this population, emphasizing early clinical warning signs and identifiable risk factors.

Pass rates for the American Midwifery Certification Board (AMCB) national certification examination (NCE) are declining. Accreditation Commission for Midwifery Education-accredited midwifery education programs are challenged to meet institutional pass rate goals and support graduates seeking to enter the midwifery workforce. There are financial, emotional, and social consequences for graduates who do not pass the AMCB NCE that undermine their success.

Multi-site neuroimaging studies have become increasingly common in order to generate larger samples of reproducible data to answer questions associated with smaller effect sizes. The data harmonization model NeuroCombat has been shown to remove site effects introduced by differences in site-related technical variance while maintaining group differences, yet its effect on improving statistical power in pre-clinical models of CNS disease is unclear. The present study examined fractional anisotropy data computed from diffusion weighted imaging data at 3 and 30 days post-controlled cortical impact injury from 184 adult rats across four sites as part of the Translational-Outcome-Project-in-Neurotrauma (TOP-NT) Consortium.

Theory predicts that high population density leads to more strongly connected spatial and social networks, but how local density drives individuals' positions within their networks is unclear. This gap reduces our ability to understand and predict density-dependent processes. Here we show that density drives greater network connectedness at the scale of individuals within wild animal populations.

The intimate relation between astrocytes and blood vessels was proposed by Camillo Golgi in 1870. Santiago Ramon y Cajal subsequently introduced the idea of astrocytes as regulators of functional hyperaemia accompanying neuronal activity in 1895. In 2003 Giorgio Carmignoto, Micaela Zonta, Tullio Pozzan and their colleagues revealed mechanisms of astrocytic control over vasodilatation.

Objective: Referred to as "skin-deep resilience," previous studies have found that striving-characterized by high levels of self-control and perseverance-is linked with better psychological health, but worse physical health, particularly among youth of color who have low socioeconomic status. However, the underlying mechanisms are unclear. This study investigated the role of sleep reactivity (poorer sleep following daily stress) in skin-deep resilience by examining the associations among striving, sleep reactivity, psychological health, and a subclinical marker of cardiovascular disease.

Background: Decompressive hemicraniectomy (DHC) can improve outcome in patients with elevated intracranial pressure (ICP) refractory to medical therapy. However, this transition point for treating refractory ICPs with DHC is unclear as ICPs can often be controlled with escalating doses of medical management. A more individualized and precise way to monitor and define medically "refractory ICP" may be achieved with the utilization of a quantitative electroencephalography (EEG) parameter called burst suppression ratio (BSR).

Left hemisphere stroke causes functional changes to the language network and may shift aspects of language processing to right hemisphere homotopes of perisylvian language regions. The result of right hemisphere recruitment is unclear. Studies suggest the right pars triangularis (rPTr) engagement in language processing corresponds to higher dysfunction.

Aim: To investigate cardiopulmonary changes using transthoracic echocardiography (TTE) in NCPH and their correlation with clinical features.

Methods: Prospective cohort including 10 preclinical NCPH [without portal hypertension (PH)] and 32 NCPH subjects who underwent TTE with agitated saline injection and comprehensive clinical evaluation were assessed.

Primary cutaneous Epstein-Barr virus (EBV)-positive polymorphic B-cell lymphoproliferative disorder (LPD) is a rare LPD associated with iatrogenic and endogenous immune dysregulation with the commonest risk factor being immunosuppressive therapy. We present a 55-year-old woman with rheumatoid arthritis, previously on methotrexate, who developed a waxing and waning papulonodular eruption on the chest and neck. Histopathology revealed a lymphohistiocytic infiltrate with atypical EBV+/CD30+ B cells, consistent with EBV+ polymorphic B-cell LPD.

Introduction: Aortic stenosis (AS) is treated with either transcatheter aortic valve replacement (TAVR) or Surgical aortic valve replacement (SAVR). However, limited data exist to study the postoperative clinical outcomes in patients with AS and chronic kidney disease (CKD). The objective of this study is to compare TAVR and SAVR postoperative clinical outcomes in patients with AS and CKD.
