This paper reviews the relationship between RBD and PD and the pathophysiology. Most RBD patients develop PD within 14 years. PD pathophysiology is α-synucleinopathy with dopamine degeneration in nigrostriatal pathways. RBD pathology is poorly understood. Anomalies suggest RBD and PD are different, evidenced by smoking. RBD and PD are associated with glucocerebrosidase gene mutations (GBA gene), suggesting RDB with GBA gene mutation predicts PD. PET imaging, assessing vesicular monoamine transporter 2 (VMAT2), inde [...]

This research aims to examine cross-sectional and longitudinal associations of positive subjective well-being among centenarians and near-centenarians in the Health and Retirement Study. Participants who eventually survived to age 98 or older (N = 516) were included. Study variables included demographic characteristics, health and activities of daily living (ADL) functioning, cognitive functioning, and positive well-being. Additionally, a smaller subsample (n = 192) of participants with supplemental leave-behind qu [...]

Traumatic brain injury (TBI) caused by direct or indirect forces is a prevalent issue in contact sports, leading to symptoms such as headaches, dizziness, nausea, and neck pain. These symptoms can have long-term consequences, including neurodegenerative diseases and mood disorders. This review fills an essential gap in the literature, as current studies on physiotherapy for traumatic brain injury (TBI) in sports are limited in scope, particularly in evaluating multimodal and personalized interventions. The review a [...]

Data available on possible associations of lipids, steroid levels, and depression are conflicting. This study investigated their possible associations in a sample of youth with depression. Ninety-eight youth with depression and individually matched healthy volunteers on the basis of age and sex were enrolled for the study. The two groups had nearly similar body mass index. After fasting overnight, they underwent blood sampling for triglycerides (TG), total cholesterol, low-density lipoprotein, high-density lipoprot [...]

The complex process of skin aging results in noticeable changes, including decreased collagen content, reduced elasticity, and decreased hydration. Interventions to preserve or restore collagen, a key structural protein, may help counteract these signs. The concept of "beauty from within” through nutritional supplements is of growing interest, particularly the use of plant-based alternatives to animal-derived or synthetic collagen. This study investigated the anti-aging potential of an extract from Moldavian dragon [...]

Background: The participation of mental health professionals in multidisciplinary care teams for heart transplantation has become an international standard practice. The contribution of these professionals in this setting, which involves assessment and interventions, has not been the subject of systematic study. Methods: This paper explores how psychotherapists contribute to multidisciplinary decision making and care in transplant teams before, during, and after transplantation. To illustrate, it uses the case of a [...]

In this study, we explored the phase equilibria in blends of a nematic liquid crystal monomer and a nematic liquid crystal flexible polymer within the whole composition of the phase diagram. The crystal-nematic and nematic-isotropic transition temperatures, as well as the transition enthalpies and entropies, indicated the total miscibility in this mesogenic blend system. We also extracted an empirical axial ratio of 4.52 for the polymer from the nematic-isotropic transitions of the blends. Further, from the biphasi [...]

Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are idiopathic and progressive autoimmune hepatobiliary disorders that lead to liver failure and a need for liver transplantation in a proportion of individuals with poorly controlled disease. It is currently thought that an environmental agent triggers disease in a genetically susceptible host and to date, xenobiotics, bacteria and a human betaretrovirus have all been linked with PBC. However, there is no consensus on which agents predomina [...]

Invasive fungal infections (IFI) remain an important cause of morbidity and mortality, especially in hospitalized and immunocompromised or critically ill patients. The incidence of IFIs has been declining in liver transplant recipients (LTR). This is likely due to the evolving immunosuppressive drug regimens, improved surgical techniques and targeted antifungal prophylaxis. However, IFI still contribute to high mortality and are associated with high economic burden due to consumption of costly newer antifungal agen [...]
