Glaucoma - risk factors and current challenges in the diagnosis of a leading cause of visual impairment.

Maturitas 2022 May 13;163:15-22. Epub 2022 May 13.

University of Western Australia, Centre for Ophthalmology and Visual Sciences (incorporating the Lions Eye Institute), Perth, WA, Australia; Centre for Eye Research Australia, University of Melbourne, Royal Victorian Eye and Ear Hospital, East Melbourne, VIC, Australia; School of Medicine, Menzies Research Institute Tasmania, University of Tasmania, Hobart, TAS, Australia.

Worldwide, glaucoma affects about 3% of the population over the age of 50 years and is a leading cause of irreversible visual impairment among older people. Because glaucoma is asymptomatic in its early stages and can be challenging to diagnose clinically, it often remains undiagnosed until substantial vision loss has occurred. Efficient methods of glaucoma screening are therefore warranted for early detection of disease. Read More

Role of LL-37 in thrombotic complications in patients with COVID-19.

Cell Mol Life Sci 2022 May 21;79(6):309. Epub 2022 May 21.

Southern Marine Science and Engineering Guangdong Laboratory (Guangzhou), Guangzhou, 511458, China.

Blood clot formation induced by dysfunctional coagulation is a frequent complication of coronavirus disease 2019 (COVID-19) and a high-risk factor for severe illness and death. Neutrophil extracellular traps (NETs) are implicated in COVID-19-induced immunothrombosis. Furthermore, human cathelicidin, a NET component, can perturb the interaction between the SARS-CoV-2 spike protein and its ACE2 receptor, which mediates viral entry into cells. Read More

Childhood poverty, immune cell aging, and African Americans' insulin resistance: A prospective study.

Child Dev 2022 May 21. Epub 2022 May 21.

Center for Family Research, University of Georgia, Athens, Georgia, USA.

The present study investigated developmental pathways that can contribute to chronic disease among rural African Americans. With a sample of 342 African American youth (59% female) from the southeastern United States followed for nearly two decades (2001-2019), we examined the prospective association between family poverty during adolescence (ages 11-18) and insulin resistance (IR) in young adulthood (ages 25-29) as well as underlying biological and psychosocial mechanisms. Results indicated family poverty during adolescence forecast higher levels of IR in young adulthood, with accelerated immune cell aging at age 20 partially mediating this association. Read More

Advancing PTSD Diagnosis and the Treatment of Trauma in Humanitarian Emergencies via Mobile Health: Protocol for a Proof-of-Concept Non-Randomized Controlled Trial.

JMIR Res Protoc 2022 May 20. Epub 2022 May 20.

Faculty of Medicine and Health, the University of Sydney, 94 Mallett St, Sydney, AU.

Background: Decentralized health systems in Low and Middle-Income Countries (LMICs) impacted by humanitarian crises lack resources and a qualified workforce to attend to the overwhelming demand for mental health care in emergencies. Innovative approaches that are safe, cost-effective, and scalable are needed to address the burden of traumatic stress brought by emergencies. High mobile phone ownership rates combined with the precision of neural, cognitive, and biometric measures of trauma and its feasible integration with Artificial Intelligence (AI) makes digital application (app) interventions a promising pathway to promote precision diagnosis and high-impact care.

High lead exposure and clinical signs of toxicosis in wild Nile crocodiles (Crocodylus niloticus) from a World Heritage site: Lake St Lucia estuarine system, South Africa.

Chemosphere 2022 May 17:134977. Epub 2022 May 17.

Department of Nature Conservation, Tshwane University of Technology, South Africa.

Lead (Pb) exposure is a widespread wildlife conservation threat, but impacts on reptile populations remain poorly documented. In this study, we examined Pb exposure and accumulation in a wild population of Nile crocodiles (Crocodylus niloticus) at Lake St Lucia, South Africa. Recreational angling has occurred in the area since the 1930s and incidental ingestion of Pb fishing weights has previously been identified as a major source of Pb poisoning in the local crocodile population.

Current state of unhealthy living characteristics in White, African American and Latinx populations.

Prog Cardiovasc Dis 2022 May 16. Epub 2022 May 16.

Healthy Living for Pandemic Event Protection (HL - PIVOT) Network, Chicago, IL, USA; Fisher Institute of Health and Well-Being, College of Health, Ball State University, Muncie, IN, USA.

The United States (US) is similar to most industrialized countries in that it falls short on many of the basic metrics related to cardiovascular and overall health. These metrics include nutritional patterns, levels of physical activity (PA), cardiorespiratory fitness (CRF), and prevalence of overweight and obesity. These issues are even more apparent in underserved communities, among whom unhealthy living characteristics cluster and contribute to a disproportionate chronic disease burden. Read More
