BMC Musculoskeletal Disorders , 2010, DOI: 10.1186/1471-2474-11-124
Abstract: A retrospective chart review was conducted on female LBP patients referred to the department of physiotherapy at a local tertiary hospital over a 12 month period. A total of 98 charts were reviewed. Two physiotherapists specialized in musculoskeletal rehabilitation collected information from the medical files. Data were classified in three categories: patients' personal demographics, patients' medical condition and history, and type of physiotherapy administered. Contingency tables and chi-square test were computed to test for differences in proportions. Spearman rank correlation coefficient was calculated to examine relationships among variables.Subjects who attended their scheduled appointments were classified as adherent (40%), and those who failed to attend 2 consecutive scheduled appointments and got discharged were classified as non-adherent (60%). Factors that significantly correlated with adherence included: age (r = 0.7, p < 0.05), initial pain intensity (r = 0.5, p < 0.05), and subjective report of improvement (r = 0.7, p < 0.01). Adherence did not correlate with the type of LBP, patient occupation, experience or nationality of the physiotherapist.This study reveals an alarming level of non-adherence to physiotherapy among patients with LBP. It remains unclear as to what level of adherence is required to achieve beneficial effect of treatment. It is quite evident however, that early withdrawal from treatment would not allow the therapeutic benefits of the treatment to be realized. Future research should be directed toward developing strategies to improve adherence.Low back pain (LBP) is considered a major health problem due to its high prevalence [1,2], high probability of recurrence [3], and associated disability [4]. It is generally defined as the perception of pain in the posterior aspect of the body between the inferior border of the rib cage and the inferior gluteal fold [5]. The epidemiology and socioeconomic cost of LBP has been well documented [6-8

Journal of Nutrition and Metabolism , 2012, DOI: 10.1155/2012/642187
Abstract: Background. Physical activity (PA) is associated with health benefits and disease prevention and is often prescribed in managing many health conditions. Understanding the cultural influences is relevant in order to effectively promote PA. The objective of this study was to assess the level of PA among Saudi women, measured by daily step count, and the association between PA and health beliefs. Methods. A total of 161 eligible participants were asked to complete two questionnaires to assess health beliefs: Health Locus of Control (HLC) and Self-Efficacy Assessment Scale. Each participant was given a pedometer and a diary to record their daily PA for two weeks. Results. One hundred and five participants completed the two weeks pedometer data (mean age 26.3±7.1 years, BMI 25±4.2 kg/m2). The average pedometer score over two weeks was 5114±2213 steps. Step count had strong correlation with self-efficacy (=0.75), mild correlation with internal HLC (=0.42), and mild negative correlation with external HLC (=?0.35). Conclusion. The study demonstrates high level of inactivity among Saudi females in reference to the international recommendation for minimum activity. The data also reveal an association between PA and health beliefs. Ultimately, such information can be used to design gender- and culture-sensitive interventions that could enhance adherence to PA.

Abstract: The present study was designed to investigate the potential protective effect of melatonin as an antioxidant separately or in combination with antigens (cercarial; CAP or soluble worm; SWAP) against Schistosoma mansoni infection in hamsters. Each hamster was sensitized with an initial immunization of 0.6 ml of the extracted antigen (30 μg protein/mL). After four days, a second injection of 0.4 mL was given (20 μg protein/mL). Then, each hamster was exposed to 260 ± 20 S.mansoni cercariae followed with melatonin treatment (3.5 mg/kg) for thirty days from the 1st day of post infection. Levels of lipid peroxidation (LPO) products, catalase (CAT) activity, hepatic glutathione (GSH) and biochemical changes in the liver and kidneys functions were investigated. The results revealed a high significant increasing of LPO and decreasing of CAT and GSH in liver of infected hamsters. Biochemical observations showed severe damage in the liver enzyme activities and increasing cholesterol level in infected animals. Melatonin co-treatment with antigen to the infected-hamster attenuated the increase of LPO and restored the activity of CAT and levels of hepatic GSH. Also, the biochemical damages in the liver and kidneys functions were reduced. The present study suggests that melatonin may be useful in combating free radical-induced damage due to infection toxicity. The immunization with previous antigens resulted in a remarkable improvement on the liver enzyme activities, which were increased after infection. Thus, vaccination of hamsters with antigens (both CAP and SWAP) and melatonin treatment has more potent effect on the enhancement of antioxidant and biochemical of S. mansoni infected-hamster than each treatment separately. Immunization of the hamster with SWAP followed by melatonin was the best way among the other regime treatments to improve the biochemical and antioxidant parameters of the infected-hamsters

Current Zoology , 2009,
Abstract: Considering that the involvement of reactive oxygen species (ROS) has been implicated in the toxicity of various pesticides, this study was designed to study the ameliorative effect of Vitamin E (100 mg/kg body weight) on mice (25–30 mg) treated with diazinon (32.5 or 16.25 mg/kg body weight) organophosphate insecticide for 14 days. Subchronic DZN exposure and the protective effects of vitamins E (vitE) were evaluated for their effects on haematological indices, the enzymes concerning liver damage [plasma alanine aminotransferase (ALT), aspartate aminotaransferase (AST), alkaline phosphatise (ALP), and some parameters of kidney function (urea and creatinine) in mice. Additionally, the histopathological changes in liver and kidney tissue were examined. The high dose of diazinon (DZNH) decreased the body weight significantly at the end of experiment. Additionally, the liver and kidney were examined for histopathological changes. The high dose of diazinon decreased body weight significantly. Moreover, there was a statistically significant decrease in haemoglobin (Hb), red blood cell (RBC) and hematocrit (Hct) in diazinon-treated mice compared to controls. This decrease was partially remedied in the diazinon-treated group that also received vitE. Damage in the liver and kidney tissues was also evident as elevated plasma ALT, AST, ALP, urea and creatinine. VitE partially counteracts the toxic effect of DZN and repairs tissue damage in the liver and kidney, especially when supplemented to 1/4 LD50 intoxicated animals. Histopathological changes in liver and kidney were observed only in 32.5 mg/kg DZN given group. These results suggest that the effects of DZN are dose dependent. No pathological findings were observed in vitE + DZN-treated groups. According to the present study, we conclude that vitE can reduce the detrimental impacts of diazinon on haematological indicies, as well as liver and kidney function [Current Zoology 55(3):219–226, 2009].

Abstract: We studied possible association of Gln27Glu in β2AR gene with body mass index (BMI), anthropometric measurements and other metabolic parameters. The β2AR gene polymorphism (Gln27Glu) was identified by sequencing PCR products representing locus of interest. Based on BMI, the subjects were divided into three groups, normal weight, overweight and obese. The genotype and allele frequency were calculated separately for each group.The allelic frequency of Glu27 did not differ amongst the three groups, though the Glu27 homozygote (Glu/Glu) were more in obese subjects and had higher concentration of triglyceride, leptin and insulin compared to in the Gln27 heterozygotes and Gln/Gln homozygotes.In this study we were able to provide evidence on the influence of Gln27Glu genetic variant of β2AR gene on lipid phenotypes, insulin and leptin levels in the Saudi populations.Obesity is serious health problem among men and women. It is a multifactorial phenotype determined by genetic and non genetic factors including environmental and behavioral characteristics [1]. Extensive studies have been conducted in different populations to identify the loci contributing to obesity development. In the process, a complex picture has emerged where inter-population differences in the susceptibility genes are observed. It has been observed that catecholamines act through both β- and α adrenergic receptor which mediate through different receptor pathways [2]. Genes involved in the regulation of catecholamine function may be of particular importance for human obesity, since catecholamine via β2-3 adrenergic receptors or adrenoceptors, regulate body fat accumulation and play a central role in the regulation of energy expenditure [3]. This regulation is in part affected by the stimulation of lipid mobilization through lipolysis in fat cells, which has been associated with obesity [4,5]. β2AR are expressed in many cell types throughout the body and play a crucial role in the regulation of the cardiac,

Abstract: Background. Several studies have shown an association between codon 16 polymorphism of the β2AR gene and obesity. Methods. We studied the association between Arg16Gly polymorphism and obesity and its influence on anthropometric parameters, lipids, insulin resistance and leptin in Saudi individuals. The study group included 329 individuals (males: 109 and females: 220). Metabolic parameters, including glucose, lipids, insulin, and leptin were analyzed and anthropometric parameters including waist and hip circumference, waist/hip (W/H) ratio, and body mass index (BMI) were measured and HOMA-IR was calculated. Genotyping was conducted by DNA sequencing of 353?bp fragments, carrying the Arg16Gly polymorphic site. Results and Conclusion. Overweight and obese subjects had a significantly higher frequency of Gly16 (0.375 and 0.38, resp.) compared with normal-weight subjects (0.200). In addition, subjects carrying Gly16 allele regardless of their BMI had greater waist and hip circumference, W/H ratio, plasma lipids, leptin, glucose level, and insulin resistance as judged from the HOMA-IR, compared to those with the wild-type allele. The findings of this study show a significant association between the Arg16Gly polymorphism in β2AR gene and the development of insulin resistance, overweight, and obesity in Saudi populations with an influence on the levels of lipid and leptin. 1. Introduction Obesity is a global pandemic with multifactorial etiology, where genetic, behavioral, and environmental factors contribute to its development [1]. The search for obesity genes has been actively pursued for the last two decades. Owing to the polygenic nature of obesity, several genetic loci have been implicated in susceptibility to obesity development, under the influence of environmental and behavioral factors [2, 3]. For over two decades, interest has been directed towards the genes involved in the regulation of catecholamine function, due to the central role played by catecholamine in the regulation of energy expenditure [4]. One such group of genes is the adrenergic receptors genes (α and β), as catecholamines bind to α- and β-adrenergic receptors; they regulate body fat accumulation and account for energy expenditure. This regulation is in part affected by the stimulation of lipid mobilization through lipolysis activation in fat cells [5, 6]. The β2-adrenergic receptors (β2ARs) are G-protein coupled receptors, widely distributed in the body. Activation of β2ARs expressed in adipocytes mediates lipolysis, while stimulation of α2-adrenergic receptors (α2ARs) inhibits

Abstract: Existing literature indicates that a weight-management program that includes diet modification, Physical Activity (PA) instructions and behavioral modification in weight reduction increases obese adolescents’ participation in PA. However, the effect of such a program on obese Saudi adolescents is unknown. Objective: To examine the effects of a weight-management program in terms of decreasing Body Mass Index (BMI) and improving participation in PA in obese Saudi adolescents, and to establish whether differences exist between genders in response to a weight-management program. PA was measured by Arab Teens Life Style (ATLS) questionnaire for both groups. Results: A wide range of differences in PA and sedentary time are evident between new and weight- managed patients and two genders. PA performance was significantly higher among the weight- managed patients compared with new patients. Also, for boys there were no differences between both groups in PA performance. While, girls’ PA was significantly higher among the girls in weight- managed group compared with girls in new patients group. Weight-managed patients spend significantly less time on the computer and/or the Internet per day compared with new patients. After treatment, the mean BMI among the weight-managed patients slightly decreased. Conclusion: The study findings suggest that the weight-management program could be effective in treating Saudi obese adolescents due to its effect in BMI reduction and greater improvement in PA performance. The surprising result from this study, PA differences between the groups were because of the total PA of girls only, meaning that obesity treatment program can lower the percentage of obesity among women and increase their levels of physical activity.

Abstract: Introduction. Medical students experience significant psychological stress and are therefore at higher risk of using sedatives. There are currently no studies describing the prevalence of sedative drug use among medical students in Saudi Arabia. The aim of this study was to evaluate the prevalence and factors associated with sedative drug use among medical students in Saudi Arabia. Materials and Methods. A cross-sectional convenience sampling study gathered data by anonymous questionnaire from students enrolled at the King Saud University College of Medicine in 2011. The questionnaires collected data regarding social and demographic variables, sleep patterns, and the use of stimulant and sedative drugs since enrollment. Sedatives were defined as any pharmaceutical preparations that induce sleep. Results and Discussion. Of the 729 students who returned questionnaires, 17.0% reported sedative drug use at some time since enrollment. Higher academic year, lower grade point average, regular exercise, fewer hours of sleep per day, poorer quality of sleep, and the presence of sleeping disorders were found to be significantly associated with sedative drug use. Conclusions. Further study is required to increase our understanding of sedative drug use patterns in this relatively high-risk group, as such understanding will help in the development of early intervention programs. 1. Introduction The evidence base linking high rates of stress in students in general [1] and medical students in particular [2] is virtually unassailable. This is from both objective [3] and subjective [4] viewpoints. However, it is unclear if there is a significant level of geographical variation in these rates and a lack of data from Saudi Arabia in particular is notable [5]. As a result it is less clear if stress is a significant issue in Saudi medical students, as with other nations, and therefore coping mechanisms in this population are underexplored [5]. Indeed, a literature search reveals no previous studies linking Saudi medical students, stress levels, and coping mechanisms, although one can note the Pani paper [5], which attempted to quantify stress levels in Saudi dental students and concluded that perceived levels of stress did not always correspond with measured biological levels of stress in this group. However, only forty students participated in this study and the authors explored neither psychological aspects nor coping mechanisms associated with stress. Psychological manifestations of stress include conditions such as anxiety, [6] depression, [7, 8] or burnout [9].
