Hydrogen is a zero-emissive fuel and has immense potential to replace carbon-emitting fuels in the future. The development of efficient H sensors is essential for preventing hazardous situations and facilitating the widespread usage of hydrogen. Chemiresistors are popular gas sensors owing to their attractive properties such as fast response, miniaturization, simple integration with electronics and low cost.

Article Synopsis
  • Continuous glucose monitoring (CGM) has improved diabetes care for outpatients, but access barriers still exist, notably due to racial disparities, cost, and a lack of specialized care.
  • The commentary reviews these barriers and discusses how addressing them can lead to better diabetes management and outcomes.
  • A proposed new care model suggests incorporating CGM use into patient discharge plans, which could improve health equity and reduce emergency care needs for individuals with diabetes.

Tilapia, a widely farmed aquaculture fish, produces substantial waste, including viscera that contain extracellular matrix (ECM) utilized as a biomaterial for tissue regeneration applications. Extracting ECM from viscera requires a specific decellularization method, as no standardized protocol exists. This study performed three decellularization methods: sonication, orbital shaking at room temperature, and agitation at 4°C, using SDS and TX100 at concentrations of 0.

Using a new analytic method ("unique non-overlapping region" (UNOR) analysis), we characterized the genotypes and phenotypes of a large cohort of individuals diagnosed with chromosome 9p deletion syndrome (9PMS) and defined critical genomic regions. We extracted phenotypic information from 48 individuals with 9PMS from medical records and used a guided interview with caregivers to clarify ambiguities. Using high-resolution whole-genome sequencing for breakpoint definition, we aligned deletions and drew virtual breakpoints to obtain UNORs associated with phenotypic characteristics.

Article Synopsis
  • Young people with Duchenne muscular dystrophy (DMD) are at a higher risk for obesity, and this study aimed to explore a weight management program tailored for them and their families.
  • The Supporting Nutrition and Optimizing Wellbeing Program (SNOW-P) was a 6-week intervention conducted via telehealth, focusing on diet and behavior, and involved feedback from caregivers to shape its structure.
  • Results showed high participation and satisfaction, indicating feasibility and acceptability, but suggested improvements like the need for better online resources and a more accurate way to track weight and dietary habits.

Article Synopsis
  • The study investigates the challenges and perceptions caregivers face regarding nutrition and weight management for children with Duchenne muscular dystrophy (DMD), given that obesity can worsen health outcomes for these kids.
  • Researchers surveyed 53 caregivers across Australian clinics, revealing that nearly half believed their child was overweight, with over half citing issues like self-esteem and movement difficulties related to weight.
  • Caregivers expressed a desire for a structured, intensive six-week weight management program that would focus on appetite control and reducing screen time but identified barriers such as time constraints and a lack of nutrition knowledge.

Pulmonary hypertension (PH) associated with chronic kidney disease (CKD) (PH-CKD) affects approximately 20%-40% of CKD patients and is associated with increased morbidity and mortality. PH and CKD are both pathophysiologically associated with nitric oxide (NO) deficiency. The NO pathway, an important therapeutic domain in pulmonary arterial hypertension (PAH), is an intriguing but unexplored target in PH-CKD.

Background: ATL1102 is a 2'MOE gapmer antisense oligonucleotide to the CD49d alpha subunit of VLA-4, inhibiting expression of CD49d on lymphocytes, reducing survival, activation and migration to sites of inflammation. Children with DMD have dystrophin deficient muscles susceptible to contraction induced injury, which triggers the immune system, exacerbating muscle damage. CD49d is a biomarker of disease severity in DMD, with increased numbers of high CD49d expressing T cells correlating with more severe and progressive weakess, despite corticosteroid treatment.

Purpose Of Review: Telomere biology disorders (TBD) are a group of genetic disorders characterized by premature shortening of telomeres, resulting in accelerated aging of somatic cells. This often leads to major multisystem organ dysfunction, and TBDs have become increasingly recognized as a significant contributor to numerous disease processes within the past 10-15 years. Both research and clinical practice in this field are rapidly evolving.

Background: Sleep is essential to health and affected by environmental and clinical factors. There is limited longitudinal research examining sleep quality in homeless older adults.

Objective: To examine the factors associated with poor sleep quality in a cohort of older adults in Oakland, California recruited while homeless using venue-based sampling and followed regardless of housing status.

Patients with pulmonary hypertension (PH) who undergo endotracheal intubation have an increased risk of adverse outcomes, but little is known regarding prognostic factors and there is limited evidence to guide management. We sought to define characteristics, prognostic factors, and outcomes of critically ill patients with PH who underwent intubation. We performed a single-center retrospective cohort study of critically ill patients with group 1, 3 or 4 PH who underwent intubation.

Milkfish () is an abundant fish commodity in the Philippines that generates a large number of wastes such as skin, scales, viscera, and bones, which, upon disposal, cause environmental pollution. The abundance of these wastes, such as fish skin, rich in bioactive natural products such as collagen, elicits interest in their conversion into high-market-value products. The decellularization of milkfish skin waste can extract its extracellular matrix (ECM), a potential raw material for biomedical applications such as the repair of damaged skin tissues.

Article Synopsis
  • Symptoms and severity of facioscapulohumeral muscular dystrophy (FSHD) can vary widely, making it essential to have reliable methods for assessing disease progression.
  • A study involving eleven pediatric patients used whole body muscle MRI to analyze muscle conditions like atrophy and fat replacement, finding strong correlations with functional outcome measures.
  • The research suggests using semi-quantitative visual scores from MRI as a reliable way to gauge disease severity in children with FSHD, especially focusing on atrophy and fat replacement rather than muscle edema.

  • The study analyzed trends in portopulmonary hypertension (POPH) exception criteria for liver transplants from 2006 to 2019, revealing a total of 504 exceptions granted for patients.
  • There has been a noted increase in both the severity of liver disease and the age of patients over the years, alongside significant improvement in treatments that positively impacted hemodynamic measures.
  • Despite improvements in treatment and patient health metrics, there have been no significant changes in mortality rates on the transplant waitlist or after liver transplants during the study period.

CT examinations contain opportunistic body composition data with potential prognostic utility. Previous studies have primarily used manual or semiautomated tools to evaluate body composition in patients with colorectal cancer (CRC). The purpose of this article is to assess the utility of fully automated body composition measures derived from pretreatment CT examinations in predicting survival in patients with CRC.

Background And Objectives: The homeless population in the US is aging. Cognitive impairment is prevalent in this population, yet little is known about the neurologic etiologies of such impairment. Addressing this gap in knowledge is important because homeless older adults with cognitive impairment due to neurodegenerative disease may need lifelong tailored support to obtain and maintain housing.

Article Synopsis
  • The study focused on how the COVID-19 pandemic led to a shift from in-person appointments to telehealth (TH) in a neuromuscular clinic, exploring perceptions of TH from parents, children, and clinicians, and aiming to create a future care model.
  • Data from a clinical audit and surveys revealed that while 62.8% of appointments were via TH in 2020, all groups preferred in-person interactions, though many parents recognized TH advantages, including reduced stress.
  • The study concluded by creating a checklist for future hybrid care combining TH and in-person visits while emphasizing the need for more research on TH's health impacts in pediatric neuromuscular treatment.
