Neurodegenerative diseases are amongst the leading causes of worldwide disability, morbidity and decreased quality of life. They are increasingly associated with the concomitant worldwide epidemic of obesity. Although the prevalence of both AD and PD continue to rise, the available treatment strategies to combat these conditions remain ineffective against an increase in global neurodegenerative risk factors. There is now epidemiological and mechanistic evidence associating obesity and its related disorders of impaired glucose homeostasis, type 2 diabetes mellitus and metabolic syndrome with both AD and PD. Here we describe the clinical and molecular relationship between obesity and neurodegenerative disease. Secondly we outline the protective role of weight loss, metabolic and caloric modifying interventions in the context of AD and PD. We conclude that the application of caloric restriction through dietary changes, bariatric (metabolic) surgery and gut hormone therapy may offer novel therapeutic strategies against neurodegenerative disorders. Investigating the protective mechanisms of weight loss, metabolic and caloric modifying interventions can increase our understanding of these major public health diseases and their management.

The accurate non-invasive detection and estimation of central aortic pressure waveforms (CAPW) are crucial for reliable treatments of cardiovascular system diseases. But the accuracy and practicality of current estimation methods need to be improved. Our study combines a meta-learning neural network and a physics-driven method to accurately estimate CAPW based on personalized physiological indicators.

Rationale: Obesity is an increasing medical issue not responding well to behavioural treatments beyond their initial weeks/months.

Aims And Objectives: Before suggesting surgical or pharmacological interventions, medical professionals might consider referrals to cost-effective, community-based behavioural treatments if stronger theoretical/empirical bases were demonstrated. Thus, evaluation of such is warranted.

Background: Use of health applications (apps) to support healthy lifestyles has intensified. Different app features may support effectiveness, including gamification defined as the use of game elements in a non-game situation. Whether health apps with gamification can impact behaviour change and cardiometabolic risk factors remains unknown.

Purpose: This study aims to investigate the possible impacts of fasting on physical activity and weight loss in adult users of glucagon-like peptide-1 (GLP-1) agonists, specifically semaglutide and tirzepatide, using qualitative methods to gain in-depth insights into participants' experiences and perceptions.

Patients And Methods: A qualitative study was conducted at the Polyclinic at King Faisal University, Al-Ahsa, Saudi Arabia, during and after Ramadan in 2024, along with the completion of International Physical Activity Questionnaires (IPAQs). The semi-structured interviews and the IPAQ were used to assess physical activity levels.
