Eli Lilly's Zepbound outperformed Novo Nordisk's Wegovy in weight loss, with 20.2% average loss vs. 13.7% over 72 weeks, according to the SURMOUNT-5 study. Zepbound, a dual GIP and GLP-1 receptor agonist, achieved 47% greater relative weight loss and better secondary outcomes. Despite Zepbound's superiority, GLP-1 medications vary in effectiveness, necessitating individualized treatment plans.

CVI visuospatial deficits involve differential recruitment of dorsal and ventral visual streams, with ventral stream showing greater activation in CVI patients, suggesting a complex clinical profile.

Vanderbilt University receives up to $46 million from ARPA-H to develop a vaccine against all alphaviruses, led by Jens Meiler and a multidisciplinary team. The project aims to use advanced technologies like computational modeling and AI for long-lasting protection, addressing a critical gap in global health.

Danielle Griffin, despite easy access to weight loss drugs like Wegovy, found they didn't work for her, losing only 13 pounds in a year and a half. Experts estimate that up to 20% of patients may not respond well to these medications, influenced by factors like genetics, hormones, and medical conditions. Alternative drugs or lifestyle changes may be necessary for effective weight management.

Tryptamine Therapeutics completes Phase Ib trial of TRP-8803, an IV-infused psilocin formulation for obesity, with all participants safely discharged. Results will inform Phase II dose optimization.

The 'Nuclear Imaging Equipment Pipeline Report, 2024 Update' provides comprehensive details on pipeline products, clinical trials, and key companies involved in nuclear imaging equipment development, aiding strategic R&D, market entry, and mergers and acquisitions.

HIV research transformed from a death sentence to a manageable condition, impacting COVID-19, cancer treatments, and vaccine development. Key insights include HIV's rapid mutation, integration into host DNA, and immune evasion, driving advancements in antiretroviral therapy and pre-exposure prophylaxis. Elite controllers' immune responses offer hope for a vaccine, with ongoing trials in Africa and South Africa.

Alzheimer’s disease research faces challenges due to complex pathology and model inaccuracies. A 3D cell culture model, 'Alzheimer’s in a dish,' and a computational tool, IPAA, identify 83 dysregulated pathways common to both human brains and the model, validating its use for drug testing and revealing potential targets like the p38 MAPK pathway.

Researchers developed an algorithm to assess how well Alzheimer's disease models mimic patient brain function and gene expression, identifying shared pathways crucial for drug discovery. The 'Alzheimer's in a dish' model, which accelerates drug testing, was confirmed to accurately reflect human brain changes, enabling rapid and scalable drug testing.
