Association Between Visceral Fat and Lung Function Impairment in Overweight and Grade I Obese Women: A Cross-Sectional Study.

Beyond the common comorbidities related to obesity, such as type 2 diabetes and cardiovascular diseases, impaired lung function is already known, but whether the fat distribution (sub-cutaneous, visceral) affects the lung function and pulmonary immune response are poorly known. Few evidence has shown that visceral fat is associated with insulin resistance, low-grade inflammation, and reduced lung function. In the present study, the body composition and fat distribution were evaluated by multi-frequency octopolar bioimpedance.

The Impact of Cannabidiol Treatment on Anxiety Disorders: A Systematic Review of Randomized Controlled Clinical Trials.

Generalized Anxiety Disorder (GAD) is a common psychiatric condition characterized by persistent and excessive worry, often accompanied by dysautonomic symptoms that significantly impact patients' well-being. Cannabidiol (CBD), a non-psychoactive compound derived from cannabis, has shown potential as an anxiolytic through its partial agonism of the 5HT-1A receptor and its negative allosteric modulation of CB1 receptors, which may help mitigate the anxiogenic effects of tetrahydrocannabinol (THC). This study evaluates the impact of CBD on individuals diagnosed with various anxiety disorders, comparing its effects to placebo and conventional pharmaceutical treatments through a systematic review of randomized controlled trials (RCTs).

The complexity of the gastrointestinal system plays a crucial role in coordinating essential processes such as digestion, nutrient absorption, and waste elimination. inflammatory bowel diseases (IBD) pose significant treatment challenges due to their complex aetiology and varied symptoms. Conventional therapeutic approaches often involve pharmacological interventions, which may have side effects and limited efficacy.

Does electrophysical agents work for cellulite treatment? a systematic review of clinical trials.

Unlabelled: Cellulite, a perceived alteration in skin topography, is predominantly found in adipose tissue-rich body regions such as the hips, buttocks, thighs, and abdomen. Contrary to common belief, the etiology and pathophysiology of cellulite are not well-established or universally agreed upon. This lack of understanding about the actual etiology of cellulite directly influences the selection of suitable treatments that can address both the aesthetic and inflammatory aspects of the condition.

Effects of photobiomodulation on pain, lactate and muscle performance (ROM, torque, and EMG parameters) of paretic upper limb in patients with post-stroke spastic hemiparesis-a randomized controlled clinical trial.

The objective of the study was to investigate the impact of photobiomodulation (PBM) on the paretic upper limb in post-stroke patients with spastic hemiparesis and to understand the potential of PBM as a long-term non-invasive therapy for reducing the side effects caused by spasticity in the hemiparetic upper limb after a stroke. This is a double-blind randomized clinical trial constituted of 27 participants, being Control group (CG = 12 healthy individuals) and PBM group (PBMG = 15 post-stroke individuals). In the CG, the baseline blood lactate (BL) was evaluated, followed by the evaluation of the IC torque of the biceps and triceps muscles, with the isokinetic dynamometer associated with surface electromyography (EMG) and, subsequently, a new measurement of BL.

Improved Spatial Memory And Neuroinflammatory Profile Changes in Aged Rats Submitted to Photobiomodulation Therapy.

Recent evidences have shown the therapeutic potential of transcranial photobiomodulation on traumatic brain injury and Alzheimer's disease. Despite the promising benefits in the brain, little is known about the laser's effects in the absence of pathological conditions. We submitted young (4 months old) and aged (20 months old) rats to transcranial low-level laser and evaluated their exploratory activity and habituation in open field, anxiety in elevated plus maze, spatial memory in Barnes maze, and aversive memory in a step-down inhibitory avoidance task.

Effects of Chronic Photobiomodulation with Transcranial Near-Infrared Laser on Brain Metabolomics of Young and Aged Rats.

Since laser photobiomodulation has been found to enhance brain energy metabolism and cognition, we conducted the first metabolomics study to systematically analyze the metabolites modified by brain photobiomodulation. Aging is often accompanied by cognitive decline and susceptibility to neurodegeneration, including deficits in brain energy metabolism and increased susceptibility of nerve cells to oxidative stress. Changes in oxidative stress and energetic homeostasis increase neuronal vulnerability, as observed in diseases related to brain aging.
