(Press-News.org) In a Perspective, Daniel Drucker highlights the growing body of evidence that hints at the potential of glucagon-like peptide-1 (GLP-1)-based medications in treating conditions other than diabetes and obesity, including cardiovascular disease and neurodegenerative disorders. GLP-1 is a hormone released from the gut after eating that enhances glucose-dependent insulin secretion. Pharmacological GLP-1 receptor (GLP-1R) activation reduces glucagon secretion and slows gastric emptying, making it an effective treatment for type 2 diabetes. Later studies found that GLP-1 administration also inhibited food intake through GLP-1R activation in the brain, leading to their use in treating obesity. Recently, research has demonstrated that GLP-1 drugs produce additional health benefits beyond glucose and weight control, including reduced heart and kidney diseases. Here, Drucker discusses the potential mechanisms underlying these benefits, such as reducing systemic inflammation, and their implications for future clinical applications and drug development. According to Drucker et al., GLP-1 drugs have shown promise in treating metabolic liver disease, with clinical trials currently underway. Although they have been found to reduce live inflammation and kidney disease complications, the exact mechanisms remain unclear. GLP-1R agonists also reduce systemic inflammation, with their effects mediated through various cellular pathways and receptors, including those in the brain. Additionally, GLP-1 medications are being explored for neurological and psychiatric disorders such as Parkinson's disease, cognitive dysfunction, depression, and substance use disorders. Initial findings suggest potential benefits, Drucker notes that more research is needed to confirm their effectiveness in these areas. “The initial chapter of GLP-1 innovation focused on glucose control, and later, weight loss. Subsequent waves seem likely to improve health outcomes in people with a range of chronic disorders,” writes Drucker. “A wide range of clinical trials is underway, with results likely to support expansion of the range of clinical indications benefiting from GLP-1 therapies.”

Urgent action needed to combat rising antimalarial resistance in Africa
2024-07-18
Artemisinin-based combination therapies (ACTs) have become the cornerstone of malaria treatment and control. However, the recent emergence and spread of artemisinin-resistance (ART-R) in malaria-causing Plasmodium falciparum parasites in eastern Africa has compromised the efficacy of these crucial treatments. In a Policy Forum, Mehul Dhorda and colleagues argue that urgent action is needed to prevent a surge in malaria-related sickness and death in the region. “Success in containing ART-R in the Greater Mekong Subregion in Asia, where ART-R was first reported in 2008, suggests that a multipronged approach is needed ...

Poking holes through membranes with atomic accuracy to build pocket-sized ‘molecule detectives’
Brussels/Washington 19/07/2024 - Transmembrane β-barrel pores (TMBs) are extensively used for single-molecule DNA and RNA sequencing. They enable the miniaturization of a wide array of sensing and sequencing applications into portable USB-size devices and point-of-care technologies. A team of Belgian and American researchers has now described a general approach to design TMB pores from scratch with custom shapes and properties, opening up new opportunities for single-molecule analytics. Their results were published ...
Genetic study highlights importance of diversity in understanding health disparities
2024-07-18
PHILADELPHIA— The majority of genetic studies focus on people of European descent, which limits the understanding of how genes influence health in other populations. Researchers at the Perelman School of Medicine at the University of Pennsylvania and the Corporal Michael J. Crescenz VA Medical Center, have partnered with a team of researchers at the Department of Veterans Affairs and the Department of Energy Oak Ridge and Argonne National Laboratories to conduct large-scale studies with diverse groups to better ...
Unhealthy sleep linked to diabetes in a diverse population
2024-07-18
Persistently unhealthy sleep, either not enough or too much, is associated with a significantly increased risk of Type 2 diabetes in a racially and economically diverse adult population, an international team of researchers has reported.
While previous research has linked suboptimal sleep durations to increased diabetes risk, the current report, published in the journal Diabetologia, extended these findings to a large cohort of primarily low-income, middle- to older-age Black and white adults in the southeastern United States.
“Our study contributes new information to support the importance of sleep health in midlife, particularly maintaining ...

Is climate change keeping patients from vital doctor appointments?
2024-07-18
Temperature extremes, becoming increasingly frequent due to growing global climate change, are associated with higher rates of missed primary care appointments, according to a recently published study from Drexel University researchers in the American Journal of Preventive Medicine.
The researchers found that rates of missed appointments increased by 0.72% for every 1°F decrease in daily maximum temperatures below 39°F and increased by 0.64% for every 1°F increase above 89°F. Patients 65 and older and those with ...
How pollution may remain in water after oil spill cleanups
2024-07-18
Oil drops from underwater oil spills can break into tinier droplets at the surface that remain suspended in the water, according to research from the University of Illinois Chicago. That means cleanups after disasters like the Deepwater Horizon spill may be removing less oil from the environment than was thought.
Because oil is lighter than water, it rises through the ocean after spills, which are usually caused by leaking underwater pipelines or sometimes by natural processes. It was believed that when these ...
World’s first method: Successful surgery for a rare congenital heart disease “scimitar syndrome”
2024-07-18
Scimitar syndrome, a rare congenital heart disease, involves an anomalous pulmonary venous return where the right pulmonary veins return to the inferior vena cava instead of the left atrium. It is mainly diagnosed in infants, with an estimated prevalence of 1–3 per 100,000 births. Delayed treatment can lead to pulmonary hypertension, right heart failure, respiratory failure, heart arrhythmia, and growth disorders.
This syndrome is characterized by anomalous pulmonary venous drainage to the inferior vena cava, and the usual surgical repair involves re-implanting the right pulmonary veins (scimitar vein) to the left atrium or creating an intra-atrial tunnel to ...
