Composite Autonomic Symptom Score-31 for the diagnosis of cardiovascular autonomic dysfunction in long-term coronavirus disease 2019.

Background: Composite Autonomic Symptom Score-31 (COMPASS-31) is an easy-to-use screening tool for the evaluation of autonomic dysfunction in various diseases affecting neural function but has rarely been used in the assessment of long coronavirus disease 2019 (COVID-19). This study aimed to evaluate the diagnostic accuracy of the COMPASS-31 score in detecting dysfunction of the autonomic nervous system in patients 3 months after COVID-19 infection.

Materials And Methods: Fifty-nine subjects were recruited and grouped into 2: (a) controls ( = 31) who had never had positive polymerase chain reaction results for COVID-19 before and (b) the post-COVID-19 patients ( = 28) who had confirmed COVID-19 infection 3-6 months before recruitment.

Association of sleep duration and quality with depression Among University Students and Faculty.

Background And Aim: Highly competitive and demanding environments in educational institutions led to reduced sleep time for both students and faculty globally. The primary objective of this study was to determine the duration and quality of sleep among students and faculty of Imam Abdulrahman Bin Faisal University (IAU). The secondary objective was to explore the relationship between depression and sleep duration and quality among students and faculty.

Variations of Ghrelin and Obestatin Hormones During the Menstrual Cycle of Women of Different BMIs.

Introduction: The cyclical changes of hormones during the menstrual cycle are responsible not only for reproductive function but also have other effects on dietary intake and appetite. The current study aimed to investigate the variations of appetite-related hormones (ghrelin and obestatin) during the menstrual cycle and their association with adipokines, estrogen, and BMI.

Methods: Fifty-six regularly menstruating female students were grouped into normal weight (BMI ≤24.

Patients And Methods: This cross-sectional study was conducted at Imam Abdulrahman Bin Faisal University, Dammam, from June 2020 until December 2020 on 4052 respondents from the Eastern province of Saudi Arabia. An online survey was used to collect information about various stress factors.

The Long-Term Impact of COVID-19 Pneumonia on the Pulmonary Function of Survivors.

Background: The sequelae of COVID-19 pneumonia on pulmonary function and airways inflammation are still an area of active research.

Objective: This research aimed to explore the long-term impact of COVID-19 pneumonia on the lung function after three months from recovery.

Methods: Fifty subjects (age 18-60 years) were recruited and classified into two groups: the control group (30 subjects) and the post-COVID-19 pneumonia group (20 patients).

Effect of energy drink consumption on baroreceptor sensitivity in young normal weight and overweight/obese males.

Objectives: There is lack of evidence exploring sympathetic effect by baroreceptor sensitivity in obese consuming energy drink. The purpose of this study was to investigate the acute effect of energy drink on individuals baroreceptor sensitivity in young healthy normal weight and overweight/obese males.

Methods: This cross-sectional study was performed in the Department of Physiology, Imam Abdulrahman Bin Faisal University, Kingdom of Saudi Arabia.

Assessment of baroreceptor reflex sensitivity in young obese Saudi males at rest and in response to physiological challenges.

Unlabelled: Autonomic imbalance in overweight/obese persons could lead to an increased risk of cardiovascular complications including hypertension and arrhythmias. Baroreceptor reflex sensitivity is a sensitive indicator to detect an altered sympathovagal balance in overweight/obese individuals. This study investigated the effects of overweight/obesity on baroreceptor sensitivity in young Saudi males at rest and in response to physiological challenges.

Changes in Heart Rate Variability and Baroreflex Sensitivity During Daytime Naps.

Background And Objectives: Changes in autonomic cardiac activity during night sleep are well documented. However, there is limited information regarding changes in the autonomic cardiac profile during daytime naps. Heart rate variability (HRV) and baroreflex sensitivity (BRS) are reliable measures of autonomic cardiac activity.

Effect of modified physiology laboratory sessions on the awareness and knowledge of obesity of health-related university students.

Background: Obesity is a global health problem of immense magnitude. Increased awareness and knowledge about obesity in health-care providers are essential to addressing this global issue. The aim of the present study was to assess the baseline knowledge on obesity of university students in health-related programs and evaluate the effectiveness of modified physiology laboratory (MPL) sessions in enhancing the awareness of obesity of these students by repeated exposure to physiological differences between normal weight (NW) and overweight or obese (OW/OB) individuals.

"Comparison of cardiovascular autonomic activity (heart rate variability and baroreceptor sensitivity) in young healthy females during fasting and hyperglycaemia".

Background And Aim: The present study compared cardiovascular autonomic activity and reactivity during fasting (FS) and hyperglycemia (HS) states in young healthy females.

Methods: This case crossover study was conducted on 30 females recruited by convenient sampling. Blood glucose levels were measured in FS and after oral glucose load i.

A Comparative Study of Cell Specific Effects of Systemic and Volatile Anesthetics on Identified Motor Neurons and Interneurons of (L.), Both in the Isolated Brain and in Single Cell Culture.

1. A comparative descriptive analysis of systemic (sodium pentobarbital, sodium thiopentone, ketamine) and volatile (halothane, isoflurane, enflurane) general anesthetics revealed important differences in the neuronal responses of identified motor neurons and interneurons in the isolated central nervous system (CNS) and cultured identified neurons in single cell culture of Lymnaea stagnalis (L.).

Synergistic effect of energy drinks and overweight/obesity on cardiac autonomic testing using the Valsalva maneuver in university students.

Background: Obesity and caffeine consumption may lead to autonomic disturbances that can result in a wide range of cardiovascular disorders.

Objectives: To determine autonomic disturbances produced by the synergistic effects of overweight or obesity (OW/OB) and energy drinks.

Design: Cross-sectional, analytical.

Effects of energy drink consumption on corrected QT interval and heart rate variability in young obese Saudi male university students.

Background And Objectives: Consumption of energy drinks has adverse effects on the heart that might be potentiated in obese individuals. Since the incidence of obesity and use of energy drinks is high among Saudi youth, we used non-invasive tests to study hemodynamic changes produced by altered autonomic cardiac activ.ity following consumption of energy drinks in obese male students.

Comparative study of Nigella Sativa and triple therapy in eradication of Helicobacter Pylori in patients with non-ulcer dyspepsia.

Methods: The cardiac workload, after 2 months of N.

Spinal shrinkage as a measure of spinal loading in male Saudi university students and its relationship with body mass index.

Objective: To compare spinal shrinkage in obese and non-obese young male adults and to find any correlation between them.

Methods: In 2006, 123 second-year male students studying in the Colleges of Medicine and Dentistry, King Faisal University, Dammam, Kingdom of Saudi Arabia, were examined for their weights, standing heights, and recumbent lengths. In this cross-sectional observational study, the students were grouped according to body mass index (BMI): normal range BMI <25; overweight BMI = 25-29.

Using "spinal shrinkage" as a trigger for motivating students to learn about obesity and adopt a healthy lifestyle.

Obesity is a global problem; however, relatively little attention is directed toward preparing and inspiring students of medicine and allied medical sciences to address this serious matter. Students are not routinely exposed to the assessment methods for obesity, its overall prevalence, causative factors, short- and long-term consequences, and its management by lifestyle modification. This physiology laboratory exercise involving students of medicine (n = 106) was developed to 1) introduce medical students to methods of obesity assessment and to differentiate between general and abdominal obesity, 2) generate an interest and sensitivity about obesity, and 3) stimulate thinking about modification of their lifestyle in relation to eating habits, weight control, and physical activity.
