THE EFFECTIVENESS OF TRANSLATED ENGLISH VIDEOS INTO ARABIC ON ENHANCING AL-AZHAR UNIVERSITY (AUG) ENGLISH MAJORS' LISTENING COMPREHENSION SKILLS
This study investigated the effectiveness of translated English videos into Arabic on enhancing Al-Azhar University-Gaza (AUG) English majors' listening comprehension skills. To achieve the aim of the study, the researchers adopted a quasi-experimental research design which focused on enhancing three main listening skills: getting the main idea, getting details and note taking skills by using translated English videos into Arabic. Twenty female English majors who were enrolled in a listening course during the first semester of the academic year 2016/2017 were the one group sample of the study. They attended the ten classes of the experiment and did a pre and post listening comprehension test. To analyze the data which the tool of the study provided, the researchers used Wilcoxon Test to compare the participants’ performance in the listening comprehension pre and posttests and Eta Square to measure the effect size of the study strategy. By the end of the semester, the sample of the study completed a listening comprehension test which consisted of (20) questions focused on getting the main idea, getting details and note taking skills. Results revealed that translated English videos into Arabic have a large effect on enhancing AUG English majors' listening comprehension skills. Article visualizations
Trauma care systems in Saudi Arabia: an agenda for action
Saudi Arabia is undergoing a rapid population growth that along with improved socioeconomics has led many individuals to own a car or even a number of cars per family, resulting in a greater number of vehicles on the roads. The reduced focus on good public transportation systems and the dependence on cars for transportation have created a diversity of drivers who are unfamiliar with the local driving rules and lack the basic skills for safe driving. This is in addition to some young drivers who frequently violate traffic laws and tend to speed most of the time. This unplanned expansion in road traffic has resulted in more car accidents, injuries, disabilities, and deaths. Accompanying that is an increased socioeconomic burden, depletion of human resources, emotional and psychological stress on families, and a strain on healthcare facilities. If this continues without prompt intervention, it will lead to increased insurance premiums and may become unmanageable. To minimize this impact, a national or regional multidisciplinary trauma system has to be developed and implemented. A trauma system is a preplanned, comprehensive, and coordinated regional injury response network that includes all facilities with the capability to care for the injured. Essential components of the system include trauma prevention, prehospital care, hospital care, rehabilitation, system administration, trauma care education and training, trauma care evaluation and quality improvement, along with the participation of society. Research has documented a significant decrease in morbidity and mortality from trauma after the implementation of such systems, depending on their efficiency. The purpose of this review is to discuss the problem of road traffic accidents in this country and address the trauma care system as an effective solution

Long-Term Weight Outcomes after Bariatric Surgery: A Single Center Saudi Arabian Cohort Experience
Background: Obesity is considered a global chronic disease requiring weight management through lifestyle modification, pharmacotherapy, or weight loss surgery. The dramatic increase in patients with severe obesity in Saudi Arabia is paralleled with those undergoing bariatric surgery. Although known to be beneficial in the short term, the long-term impacts of surgery within this group and the sustainability of weight loss after surgery remains unclear. Objectives: We aimed to assess the long-term weight outcomes after bariatric surgery. Setting: The study was conducted at King Khalid University Hospital (KKUH), King Saud University Medical City (KSUMC) in Riyadh, Saudi Arabia. Methods: An observational prospective cohort study on adult patients with severe obesity undergoing bariatric surgery (sleeve gastrectomy (SG) or Roux-en Y gastric bypass (RYGB)) during the period between 2009 and 2015 was conducted. Weight loss patterns were evaluated pre- and post-surgery through clinical and anthropometric assessments. Absolute weight loss was determined, and outcome variables: percent excess weight loss (%EWL), percent total weight loss (%TWL), and percent weight regain (%WR), were calculated. Statistical analysis using univariate and multivariate general linear modelling was carried out. Results: A total of 91 (46 males and 45 females) patients were included in the study, with the majority belonging to the SG group. Significant weight reductions were observed at 1 and 3 years of follow-up (p < 0.001) from baseline. The %EWL and %TWL were at their maximum at 3 years (72.4% and 75.8%) and were comparable between the SG and RYGB. Decrements in %EWL and %TWL and increases in %WR were seen from 3 years onwards from bariatric surgery until the study period ended. The yearly follow-up attrition rate was 20.8% at 1 year post-surgery, 26.4% at year 2, 31.8% at year 3, 47.3% at year 4, 62.6% at year 5, and 79.1% at end of study period (at year 6). Conclusion: The major challenge to the successful outcome of bariatric surgery is in maintaining weight loss in the long-term and minimizing weight regain. Factors such as the type of surgery and gender need to be considered before and after surgery, with an emphasis on the need for long-term follow-up to enssure the optimal benefits from this intervention
Differential patterns of serum concentration and adipose tissue expression of chemerin in obesity: Adipose depot specificity and gender dimorphism
Chemerin, a recognized chemoattractant, is expressed in adipose tissue
and plays a role in adipocytes differentiation and metabolism. Gender-
and adipose tissue-specific differences in human chemerin expression
have not been well characterized. Therefore, these differences were
assessed in the present study. The body mass index (BMI) and the
circulating levels of chemerin and other inflammatory, adiposity and
insulin resistance markers were assessed in female and male adults of
varying degree of obesity. Chemerin mRNA expression was also measured in
paired subcutaneous and visceral adipose tissue samples obtained from a
subset of the study subjects. Serum chemerin concentrations correlated
positively with BMI and serum leptin levels and negatively with high
density lipoprotein (HDL)-cholesterol levels. No correlation was found
between serum chemerin concentrations and fasting glucose, total
cholesterol, low density lipoprotein (LDL)-cholesterol, triglycerides,
insulin, C-reactive protein or adiponectin. Similarly, no relation was
observed with the homeostasis model assessment for insulin resistance
(HOMA-IR) values. Gender- and adipose tissue-specific differences were
observed in chemerin mRNA expression levels, with expression
significantly higher in women than men and in subcutaneous than visceral
adipose tissue. Interestingly, we found a significant negative
correlation between circulating chemerin levels and chemerin mRNA
expression in subcutaneous fat. Among the subjects studied, circulating
chemerin levels were associated with obesity markers but not with
markers of insulin resistance. At the tissue level, fat depot-specific
differential regulation of chemerin mRNA expression might contribute to
the distinctive roles of subcutaneous vs. visceral adipose tissue in
human obesity
