Efficacy and Safety of Prehospital Blood Transfusion in Traumatized Patients: A Systematic Review and Meta-Analysis.

Background: Approximately five million individuals have traumatic injuries annually. Implementing prehospital blood-component transfusion (PHBT), encompassing packed red blood cells (p-RBCs), plasma, or platelets, facilitates early hemostatic volume replacement following trauma. The lack of uniform PHBT guidelines persists, relying on diverse parameters and physician experience.

Effects of exercise on autonomic cardiovascular control in individuals with chronic, motor-complete spinal cord injury: an exploratory randomised clinical trial.

Study Design: Secondary analysis of a clinical trial.

Objective: To assess the impact of 6 months of arm cycle ergometry training (ACET), or body weight-supported treadmill training (BWSTT), on autonomic cardiovascular responses to a laboratory sit-up test (SUT) in individuals with chronic (≥1-year post-injury) spinal cord injury (SCI).

Setting: Tertiary Rehabilitation Centre, Vancouver, Canada.

Thermal welding tonsillectomy versus cold dissection tonsillectomy: A systematic review and meta-analysis of randomised controlled trials.

Objectives: To evaluate the efficacy of thermal welding (TW) versus cold dissection (CD) strategies among tonsillectomy patients.

Design And Setting: A systematic review and meta-analysis of randomised controlled trials (RCTs).

Participants: Patients undergoing tonsillectomy.

Motor and autonomic concomitant health improvements with neuromodulation and exercise (MACHINE) training: a randomised controlled trial in individuals with spinal cord injury.

Introduction: Motor and autonomic dysfunctions are widespread among people with spinal cord injury (SCI), leading to poor health and reduced quality of life. Exercise interventions, such as locomotor training (LT), can promote sensorimotor and autonomic recovery post SCI. Recently, breakthroughs in SCI research have reported beneficial effects of electrical spinal cord stimulation (SCS) on motor and autonomic functions.

A Sensitive Hydroquinone Amperometric Sensor Based on a Novel Palladium Nanoparticle/Porous Silicon/Polypyrrole-Carbon Black Nanocomposite.

Exposure to hydroquinone (HQ) can cause various health hazards and negative impacts on the environment. Therefore, we developed an efficient electrochemical sensor to detect and quantify HQ based on palladium nanoparticles deposited in a porous silicon-polypyrrole-carbon black nanocomposite (Pd@PSi-PPy-C)-fabricated glassy carbon electrode. The structural and morphological characteristics of the newly fabricated Pd@PSi-PPy-C nanocomposite were investigated utilizing FESEM, TEM, EDS, XPS, XRD, and FTIR spectroscopy.

Post-processing Peak Oxygen Uptake Data Obtained During Cardiopulmonary Exercise Testing in Individuals With Spinal Cord Injury: A Scoping Review and Analysis of Different Post-processing Strategies.

Objectives: To review the evidence regarding the most common practices adopted with cardiopulmonary exercise testing (CPET) in individuals with spinal cord injury (SCI), with the following specific aims to (1) determine the most common averaging strategies of peak oxygen uptake (V̇o), (2) review the endpoint criteria adopted to determine a valid V̇o, and (3) investigate the effect of averaging strategies on V̇o values in a convenience sample of individuals with SCI (between the fourth cervical and sixth thoracic spinal segments).

Data Sources: Searches for this scoping review were conducted in MEDLINE (PubMed), EMBASE, and Web Science.

Study Selection: Studies were included if (1) were original research on humans published in English, (2) recruited adults with traumatic and non-traumatic SCI, and (3) V̇o reported and measured directly during CPET to volitional exhaustion.

Associations between left ventricular structure and function with cardiorespiratory fitness and body composition in individuals with cervical and upper thoracic spinal cord injury.

Study Design: Cross-sectional.

Objective: It is known that left ventricular mass (LVM) and cardiorespiratory fitness (CRF) are associated to fat-free mass (FFM).  It is unknown if these factors associated with left ventricular (LV) structure and function outcomes in individuals with spinal cord injury (SCI).

The Relationship between Volatile Sulfur Compounds and the Severity of Chronic Periodontitis: A Cross-sectional Study.

Background: Halitosis is a problem that is often ignored or undervalued. It is not considered a major clinical issue; thus, little is carried out to eradicate it. Little is known about the relationship of malodorous breath with the severity of periodontitis.

Construct validation of the leisure time physical activity questionnaire for people with SCI (LTPAQ-SCI).

Study Design: Cross-sectional construct validation study.

Objectives: To test the construct validity of the Leisure Time Physical Activity Questionnaire for People with Spinal Cord Injury (LTPAQ-SCI) by examining associations between the scale responses and cardiorespiratory fitness (CRF) in a sample of adults living with spinal cord injury (SCI).

Setting: Three university-based laboratories in Canada.

Effects of exercise interventions on cardiovascular health in individuals with chronic, motor complete spinal cord injury: protocol for a randomised controlled trial [Cardiovascular Health/Outcomes: Improvements Created by Exercise and education in SCI (CHOICES) Study].

Introduction: Recent studies demonstrate that cardiovascular diseases and associated complications are the leading cause of morbidity and mortality in individuals with spinal cord injury (SCI). Abnormal arterial stiffness, defined by a carotid-to-femoral pulse wave velocity (cfPWV) ≥10 m/s, is a recognised risk factor for heart disease in individuals with SCI. There is a paucity of studies assessing the efficacy of conventional training modalities on arterial stiffness and other cardiovascular outcomes in this population.

Epidemiologic Pattern and Types of Oral Smokeless Tobacco Usage in Saudi Arabia.

Smokeless tobacco (ST) use is a significant health risk and cause of disease. Most studies conducted in the Kingdom of Saudi Arabia (KSA) focused on cigarette smoking. Therefore, the objective was to study the epidemiologic pattern and types of oral ST usage in northern and western Saudi Arabia.
