The Effectiveness of Virtual Reality-Based Training on Cognitive, Social, and Physical Functioning in High-Functioning Older Adults (CoSoPhy FX): 2-Arm, Parallel-Group Randomized Controlled Trial.

Background: Virtual reality (VR) has emerged as a promising technology for enhancing the health care of older individuals, particularly in the domains of cognition, physical activity, and social engagement. However, existing VR products and services have limited availability and affordability; hence, there is a need for a scientifically validated and personalized VR service to be used by older adults in their homes, which can improve their overall physical, cognitive, and social well-being.

Objective: The main purpose of the CoSoPhy FX (Cognitive, Social, and Physical Effects) study was to analyze the effects of a VR-based digital therapeutics app on the cognitive, social, and physical performance abilities of healthy (high-functioning) older adults.

Virtual reality-based training may improve visual memory and some aspects of sustained attention among healthy older adults - preliminary results of a randomized controlled study.

Background/aims: Older age and cognitive inactivity have been associated with cognitive impairment, which in turn is linked to economic and societal burdens due to the high costs of care, especially for care homes and informal care. Emerging non-pharmacological interventions using new technologies, such as virtual reality (VR) delivered on a head-mounted display (HMD), might offer an alternative to maintain or improve cognition. The study aimed to evaluate the efficacy and safety of a VR-based Digital Therapeutics application for improving cognitive functions among healthy older adults.

Expression of Dopamine D and Serotonin 5-HT Receptors in Blood Mononuclear Cells in Schizophrenia.

The aim of this study was to determine the mRNA expression profile of dopamine D, D, D, D and serotonin 5-HT, 5-HT, and 5-HT receptors in peripheral blood mononuclear cells (PBMCs) in schizophrenia and the effect of antipsychotics on the expression of these receptors in PBMCs of healthy subjects. Twenty-seven patients with schizophrenia and 29 healthy controls were recruited for the study. All study subjects underwent thorough clinical assessment, including anthropometric and body composition measurements.

Association between adiposity and fasting serum levels of appetite-regulating peptides: Leptin, neuropeptide Y, desacyl ghrelin, peptide YY(1-36), obestatin, cocaine and amphetamine-regulated transcript, and agouti-related protein in nonobese participants.

The objective of this study was to evaluate the association between adiposity parameters and fasting serum levels of appetite-regulating peptides: leptin, neuropeptide Y (NPY), desacyl ghrelin, peptide YY(1-36), obestatin, cocaine- and amphetamine-regulated transcript (CART), and agouti-related protein in 30 healthy, non-obese subjects. Thirty European Caucasian adult participants were included in the study (17 men and 13 women). Body composition (body fat and lean body mass) was determined using bioelectrical impedance analysis.

Fasting serum leptin levels in elderly women with major depressive disorder: a case-control study.

Objective: Leptin is produced in the adipose tissue. It controls energy homeostasis by reducing food intake and increasing energy expenditure. According to the "leptin hypothesis of depression", chronic stress leads to reduced leptin concentration and leptin insufficiency may underlie depressive symptoms.

In vitro cytokine synthesis in unstimulated and mitogen-stimulated peripheral blood mononuclear cells from individuals with schizophrenia.

Increasing evidence has shown that the immune system is involved in the schizophrenia development, with alterations in immune cell reactivity being one possible factor contributing to its pathogenesis. The purpose of the study was to evaluate in vitro the capability of peripheral blood mononuclear cells (PBMCs) obtained from subjects with schizophrenia and controls to engage in spontaneous and phytohemagglutinin (PHA)-stimulated cytokine production. The concentrations of various cytokines (interleukin (IL)-1β, IL-17A, tumor necrosis factor (TNF), interferon (IFN)-γ and IL-10) in supernatants from cultured PBMCs were measured using the cytometric bead array.

The expression of toll-like receptors in peripheral blood mononuclear cells is altered in schizophrenia.

Increasing evidence suggests that in addition to neurochemical abnormalities, various immunological alterations are related to the pathogenesis of schizophrenia. Toll-like receptors (TLRs) actively mediate immune/inflammatory processes and play a pivotal role in damage/danger recognizing. Therefore, the aim of this study was to compare the expression of TLRs in peripheral blood mononuclear cells (PBMCs) in schizophrenic patients with those of healthy subjects.

In schizophrenia serum level of neurotrophin-3 (NT-3) is increased only if depressive symptoms are present.

Aim: Neurotrophin-3 (NT-3) is a neurotrophic factor responsible for promoting development, survival and function of neurons. NT-3 may be involved in the etiopathology of schizophrenia and mood disorders. However it must be cleared up if changes of NT-3 level are associated with schizophrenia itself or are secondary to certain symptoms (e.

Neutrophil-lymphocyte ratio is increased in elderly patients with first episode depression, but not in recurrent depression.

Association between inflammation and depression, especially in elderly patients, leads to conclusions about their shared influence on risk of cardiovascular disease and death. It might be found useful to predict those issues by monitoring inflammatory parameters, such as neutrophil/lymphocyte ratio (NLR). The aim of this study was to determine the NLR in elderly patients with unipolar depression compared with non-depressed elderly patients.

Atherogenic Indices Are Increased in Elderly Patients with Unipolar Depression-Case-Control Analysis.

Background: Blood lipids are widely used in monitoring the risk of cardiovascular diseases; however, atherogenic indices are more precise markers. The aim of the study was to determine differences in atherogenic indices in elderly patients with unipolar depression (DEP) compared with nondepressed elderly patients (nonDEP) using case-control analysis.

Methods: Fasting serum lipid profiles were measured in 564 (depressed: n = 282, nondepressed: n = 282, 83.
