J Med Internet Res

January 2025

Learning and Capacity Development Unit, Health Emergencies Programme, World Health Organization, Geneva, Switzerland.

Background: The COVID-19 pandemic demonstrated the global need for accessible content to rapidly train health care workers during health emergencies. The massive open access online course (MOOC) format is a broadly embraced strategy for widespread dissemination of trainings. Yet, barriers associated with technology access, language, and cultural context limit the use of MOOCs, particularly in lower-resource communities.

Importance: Determining spectacle-corrected visual acuity (VA) is essential when managing many ophthalmic diseases. If artificial intelligence (AI) evaluations of macular images estimated this VA from a fundus image, AI might provide spectacle-corrected VA without technician costs, reduce visit time, or facilitate home monitoring of VA from fundus images obtained outside of the clinic.

Objective: To estimate spectacle-corrected VA measured on a standard eye chart among patients with diabetic macular edema (DME) in clinical practice settings using previously validated AI algorithms evaluating best-corrected VA from fundus photographs in eyes with DME.

Variations and Opportunities in Postnatal Management of Hemolytic Disease of the Fetus and Newborn.

JAMA Netw Open

January 2025

Division of Neonatology, Department of Pediatrics, Willem-Alexander Children's Hospital, Leiden University Medical Center, Leiden, the Netherlands.

Importance: Preventive efforts in pregnancy-related alloimmunization have considerably decreased the prevalence of hemolytic disease of the fetus and newborn (HDFN). International studies are therefore essential to obtain a deeper understanding of the postnatal management and outcomes of HDFN. Taken together with numerous treatment options, large practice variations among centers may exist.

People with disabilities have recently been declared a population at increased risk of health disparities, and research has cited a lack of physician training as a cause of that increased risk. Prior studies demonstrate that physicians lack confidence in caring for people with disabilities, but there is little research on disability competency among medical students. This study assessed medical students' confidence in six disability-related competencies and tested for associations between perceived confidence and students' personal demographics and institutional characteristics.

IP6K1 rewires LKB1 signaling to mediate hyperglycemic endothelial senescence.

Diabetes

January 2025

Institute for Developmental and Regenerative Cardiovascular Medicine, Xinhua Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 200092, China.

Diabetes is a major risk factor for cardiovascular disease, but the molecular mechanisms underlying diabetic vasculopathy have been elusive. Here we report that inositol hexakisphosphate kinase 1 (IP6K1) mediates hyperglycemia-induced endothelial senescence by rewiring the liver kinase B1 (LKB1) signaling from activating the adenosine monophosphate-activated protein kinase (AMPK) pathway to the p53 pathway. We found that hyperglycemia upregulated IP6K1, which disrupts the Hsp/Hsc70 and carboxyl terminus of Hsc70-interacting protein (CHIP)-mediated LKB1 degradation, leading to increased expression levels of LKB1.

Development and Effects of a Smartphone Application to Improve Self-Management in Workers Who Underwent Thyroid Cancer Surgery.

Cancer Nurs

January 2025

Author Affiliations: Department of Nursing, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine (Dr Kim); and College of Nursing, Hanyang University (Dr Hwang), Seoul, Republic of Korea.

Background: Although the survival rate for thyroid cancer is high, a nursing intervention that enhances autonomous motivation is needed for patients with jobs to improve their long-term self-management abilities in the early postoperative period.

Objectives: This study aims to develop a mobile application (app) based on the Self-Determination Theory for patients returning to work after thyroid cancer surgery and to verify its effectiveness.

Methods: We developed an app to promote self-management and verify its effectiveness after 12 weeks in early outpatients who underwent thyroid cancer surgery through a randomized controlled trial design.

Background: Globally, Breast Cancer (BC) is the most frequent cancer in women and has a major negative impact on the physical and emotional well-being of its patients as well as one of the most common cancers to be diagnosed. Numerous studies have been published to identify various molecular pathways, including PI3K/AKT/PTEN. Moreover, growing evidence suggests that miRNAs have been found to play a vital role in the growth and carcinogenesis of tumors.

This study discusses disseminated intravascular coagulation (DIC) associated with solid cancers and various vascular abnormalities, both of which generally exhibit chronic DIC patterns. Solid cancers are among the most significant underlying diseases that induce DIC. However, the severity, bleeding tendency, and progression of DIC vary considerably depending on the type and stage of the cancer, making generalization difficult.

Background: Reentry veterans experience many barriers to achieving physical and psychological well-being. While peer specialists can provide important support to veterans as they readjust to life post-incarceration, their specific activities and qualities most valued by veterans are not well known. The Post-Incarceration Engagement (PIE) intervention, coordinated with VA's Health Care for Reentry Veterans (HCRV) program, links reentry veterans with a peer specialist who provides connection to services and social-emotional support during the reentry process.

The tRF-33/IGF1 Axis Dysregulates Mitochondrial Homeostasis in HER2-Negative Breast Cancer.

Am J Physiol Cell Physiol

January 2025

Department of Breast and Thyroid Surgery, Affiliated Jinhua Hospital, Zhejiang University School of Medicine, Jinhua, 321000, Zhejiang Province, China.

Transfer RNA-derived small RNAs (tsRNAs), a recently identified non-coding RNA subset, are mainly classified into tRNA-derived small RNA fragments (tRFs) and tRNA-derived stress-induced RNAs (tiRNAs). tsRNAs dysregulation is frequently observed in numerous cancer types, suggesting involvement in tumorigenesis. However, their functions in breast cancer (BC) remain to be fully understood.

Aims: Whether prior treatment with angiotensin-converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARBs) modifies efficacy and safety of sacubitril/valsartan (Sac/Val) in patients with heart failure (HF) and ejection fraction (EF) >40% is unclear, thus Sac/Val according to ACEi/ARB status at baseline was assessed.

Methods And Results: This was a pre-specified analysis of Prospective comparison of ARNI with ARB Given following stabiLization In DEcompensated HFpEF (PARAGLIDE-HF), a double-blind, randomized controlled trial of Sac/Val versus valsartan, categorizing patients according to baseline ACEi/ARB status. The primary endpoint was time-averaged proportional change in N-terminal pro-B-type natriuretic peptide (NT-proBNP) from baseline through weeks 4 and 8.

Intermittent hypoxemia (IH), a pathophysiologic consequence of obstructive sleep apnea (OSA), adversely affects insulin sensitivity, insulin secretion, and glucose tolerance. Nifedipine, an L-type calcium channel blocker frequently used for treatment of hypertension, can also impair insulin sensitivity and secretion. However, the cumulative and interactive repercussions of IH and nifedipine on glucose homeostasis have not been previously investigated.

Purpose: Alteration of visual acuity in wet age-related macular degeneration (AMD) is mostly driven by vascular endothelial growth factor A (VEGF-A)-induced edema from leaky newly forming blood vessels below the retina layers. To date, all therapies aimed at alleviation of this process have relied on inhibition of VEGF-A activity. Although effective in preventing vascular leak and edema, this approach also leads to the loss of normal vasculature and multiple related side effects.

Tumor-derived extracellular vesicle (tEV)-associated RNAs hold promise as diagnostic biomarkers, but their clinical use is hindered by the rarity of tEVs among nontumor EVs. Here, we present EV-CLIP, a highly sensitive droplet-based digital method for profiling EV RNA. EV-CLIP utilizes the fusion of EVs with charged liposomes (CLIPs) in a microfluidic chip.
