Resistive exercise training has become very popular for patients of cardiopulmonary rehabilitation programmes (CRPs). For decades, CRPs focused almost exclusively on improving cardiorespiratory endurance and most programmes ignored muscular fitness development. Moreover, resistance training was thought to be potentially hazardous for the cardiac patient due to the risk of cardiovascular complications from adverse haemodynamic responses. We now know that resistive exercise testing and training is very safe for properly screened patients, even at relatively high workloads. Improvement in muscular strength facilitates return to daily vocational and avocational activities and is important for the CRP participant to regain lost strength and resume work soon after a cardiac event. Circuit weight training (CWT) is helpful in this respect and has been shown to increase muscular strength, cardiovascular endurance, body composition, bone density and mineral content, self-confidence, and self-efficacy in various populations. This article presents an update on current research in cardiac patients and also presents guidelines for implementing a properly supervised cardiac resistive exercise programme.

Lipedema is characterized by abnormal fat deposition in areas such as the arms, hips, buttocks, and thighs, sparing the hands and feet. Symptoms include pain, bruising, edema, and subcutaneous nodules, which resist traditional interventions such as diet and exercise. Despite increasing recognition, comprehensive understanding, including pathophysiological, clinical, and therapeutic aspects, has not been fully achieved.

5-Hydroxyindoleacetic acid (5-HIAA), a vital metabolite of serotonin (5-HT), is crucial for understanding metabolic pathways and is implicated in various mental disorders. In situ monitoring of 5-HIAA is challenging due to the lack of affinity ligands and issues with electrochemical fouling. We present an advanced sensing approach that integrates customizable molecular imprinting polymer (MIP) with self-driven galvanic redox potentiometry (GRP) for precise, real-time in vivo monitoring of 5-HIAA.

According to epidemiological studies, diabetes is more common in patients with AD, which suggests that diabetes is a significant risk factor for AD. Accelerating brain cell degeneration, worsening cognitive decline, and increasing susceptibility to AD can be attributed to pathogenic mechanisms linked to diabetes, such as impaired insulin signaling in the brain, neuroinflammation, oxidative stress, mitochondrial dysfunction, and vascular impairment. These factors can also lead to the accumulation of β-amyloid and tau protein phosphorylation.

Muscle atrophy occurs with extended exposure to microgravity. This study quantified the overall muscle size, lean muscle area and fat infiltration changes pre- to post-flight that occur in the thoracic and lumbar spine with long-duration spaceflight. Pre- and post-flight magnetic resonance imaging (MRI) scans were obtained from 9 crewmembers on long-duration (≥6 months) International Space Station (ISS) missions.
