Effect of Leadership Support, Work Conditions and Job Security on Job Satisfaction in a Medical College.

BACKGROUND: Faculty members are crucial elements of an educational institution, and their job satisfaction is likely essential for success of the educational process. Leadership support, work conditions and perceived job security could be factors affecting academic job satisfaction. OBJECTIVE: The aim of the study was to investigate the effect of leadership support, work conditions and perceived job security on the overall academic job satisfaction of faculty. MATERIALS AND METHODS: A cross-sectional survey, using a structured questionnaire, was conducted to determine the effect of leadership support, work conditions and perceived job security on academic job satisfaction among faculty and teaching staff at the College of Medicine, Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. Multiple regression analysis was performed to examine the significance of these relationships at 95% confidence interval and P < 0.05 level of significance. RESULTS: Leadership support (ß = 0.187, t = 2.714, P = 0.007), work conditions (ß = 0.199, t = 2.628, P= 0.009) and perceived job security (ß = 0.264, t = 3.369, P = 0.001) were found to be significantly associated with overall academic job satisfaction. CONCLUSION: The results of this study support the hypothesis that faculty and teaching staff working with supportive leaders and favorable work conditions as well as having an optimized sense of perceived job security demonstrate significantly higher levels of overall academic job satisfaction. These findings provide input for policymakers, and their implementation could enhance an institution's vitality and performance, and thus enable it to fulfill its goals.

Profile of non-communicable disease risk factors among employees at a Saudi university.

BACKGROUND: There is paucity of studies defining the prevalence of non-communicable disease (NCD) risk factors in Saudi Arabia despite the surging epidemic of obesity, change in dietary habits and sedentary lifestyle. OBJECTIVES: This cross-sectional study aimed to assess the prevalence of NCDs risk factors among employees at King Faisal University in Al Hassa, Saudi Arabia and to determine the possible correlates for clustering of NCDs risk factors among them. MATERIALS AND METHODS: All employees were invited to participate; the World Health Organization STEPwise approach was used for data collection which consisted of a personal interview to collect socio-demographic characteristics, NCD history, tobacco use, vegetables and fruit consumption, and physical activity (PA), followed by anthropometric measurements namely weight, height and waist circumference and blood pressure measurements, subjects were finally subjected to biochemical tests with determination of fasting plasma glucose, serum triglycerides, cholesterol and high density lipoproteins. RESULTS: Of the surveyed employees (n=691), daily current smokers accounted for 22.7%. 94.9%, 95.1% and 86% consumed < 5 servings per day of vegetables, fruits and both fruits and vegetables respectively, 73% were physically inactive, 64% were overweight or obese, 22.1% had hypertension, and 21.5% were diabetics. Elevated cholesterol levels were found in 36.6%, low high density lipoproteins in 36.8%, and elevated triglycerides in 36.1%. Only 3% had no NCD risk factors, and 57.6% had ≥3 factors. Multivariate logistic regression showed that gender (being male, adjusted odds ratio 'aOR'=1.51), aged ≥ 50 years (aOR=3.06), < college education (aOR=1.75), current smokers (aOR=2.37), being obese (aOR=6.96) and having a low PA level (aOR=4.59) were the significant positive predictors for clustering of NCD risk factors. CONCLUSIONS: Over fifty percent of the studied university's employees had multiple (≥3) NCD risk factors. Screening and health promotion initiatives should be launched at least targeting the modifiable factors to avert the excessive risk for cardiovascular disease, diabetes mellitus and several types of cancers.

Coenzyme Q10 counteracts testicular injury induced by sodium arsenite in rats.

The protective effect of coenzyme Q10 against testicular toxicity induced by sodium arsenite (10mg/kg/day, orally for two consecutive days) was investigated in rats. Coenzyme Q10 treatment (10mg/kg/day, i.p.) was applied for five consecutive days, starting three days before arsenite administration. Coenzyme Q10 significantly increased serum testosterone level which was reduced by sodium arsenite. Coenzyme Q10 significantly suppressed lipid peroxidation, restored the depleted antioxidant defenses, and attenuated the increases of tumor necrosis factor-α and nitric oxide resulted from arsenic administration. Also, the elevation of arsenic ion, and the reductions of selenium and zinc ions in testicular tissue were mitigated by coenzyme Q10. Histopathological examination showed that testicular injury mediated by arsenic was ameliorated by coenzyme Q10 treatment. Immunohistochemical analysis revealed that coenzyme Q10 significantly decreased the arsenic-induced expression of inducible nitric oxide synthase, nuclear factor-κB, Fas ligand and caspase-3 in testicular tissue. It was concluded that coenzyme Q10 represents a potential therapeutic option to protect the testicular tissue from the detrimental effects of arsenic intoxication.

Coenzyme Q10 treatment ameliorates acute cisplatin nephrotoxicity in mice.

The nephroprotective effect of coenzyme Q10 was investigated in mice with acute renal injury induced by a single i.p. injection of cisplatin (5 mg/kg). Coenzyme Q10 treatment (10 mg/kg/day, i.p.) was applied for 6 consecutive days, starting 1 day before cisplatin administration. Coenzyme Q10 significantly reduced blood urea nitrogen and serum creatinine levels which were increased by cisplatin. Coenzyme Q10 significantly compensated deficits in the antioxidant defense mechanisms (reduced glutathione level and superoxide dismutase activity), suppressed lipid peroxidation, decreased the elevations of tumor necrosis factor-alpha, nitric oxide and platinum ion concentration, and attenuated the reductions of selenium and zinc ions in renal tissue resulted from cisplatin administration. Also, histopathological renal tissue damage mediated by cisplatin was ameliorated by coenzyme Q10 treatment. Immunohistochemical analysis revealed that coenzyme Q10 significantly decreased the cisplatin-induced overexpression of inducible nitric oxide synthase, nuclear factor-kappaB, caspase-3 and p53 in renal tissue. It was concluded that coenzyme Q10 represents a potential therapeutic option to protect against acute cisplatin nephrotoxicity commonly encountered in clinical practice.

Ameliorative effects of telmisartan in diabetic rats with indomethacin-induced gastric ulceration.

The protective effects of telmisartan, the angiotensin II-receptor antagonist, were investigated in rats with type 2 diabetes mellitus exposed to acute gastric ulceration. Following successful induction of diabetes, telmisartan treatment (1 mg/kg/day, orally) was started and continued for 8 weeks, after which acute gastric ulceration was induced by indomethacin. Telmisartan significantly attenuated the hyperglycemia and hypoinsulinemia in diabetic rats. Also, telmisartan significantly reduced the elevations of total gastric acid output, pepsin activity, gastric ulcer index and gastric mucosal tumor necrosis factor-alpha, nitric oxide, malondialdehyde and caspase-3 activity, and restored the depleted antioxidant defenses (reduced glutathione level, and superoxide dismutase and catalase activities) caused by indomethacin administration in diabetic rats. Histopathological gastric tissue damage induced by indomethacin in diabetic rats was ameliorated by telmisartan treatment. Immunohistochemical analysis revealed that telmisartan markedly attenuated the reduction in insulin content of pancreatic islet beta-cells, and prevented the indomethacin-induced overexpression of inducible nitric oxide synthase and nuclear factor-kappaB in gastric mucosa of diabetic rats. It was concluded that telmisartan represents a potential therapeutic option to reduce the risk of gastric ulceration induced by nonsteroidal anti-inflammatory drugs in type 2 diabetic patients.

Nephroprotective effect of telmisartan in rats with ischemia/reperfusion renal injury.

We investigated the protective effect of telmisartan, an angiotensin II receptor antagonist, against ischemia/reperfusion renal injury in rats. Bilateral ischemia was induced by clamping both renal vascular pedicles for 45 min followed by reperfusion for 3 h. Untreated rats exposed to ischemia/reperfusion showed significant elevations in blood urea nitrogen and serum creatinine levels, renal tissue levels of malondialdehyde, tumor necrosis factor-alpha and nitric oxide, and caspase-3 activity. This was associated with significant decreases in renal reduced glutathione level, catalase and superoxide dismutase activities. Also, significant increases in serum and renal tissue levels of homocysteine were detected following ischemia/reperfusion. Pre-ischemic treatment with telmisartan (0.3 mg/kg/day, i.p.) for 7 consecutive days significantly attenuated the increases in blood urea nitrogen, serum creatinine, renal malondialdehyde, tumor necrosis factor-alpha, nitric oxide, caspase-3 activity, and serum and renal homocysteine levels, and significantly restored the renal antioxidant defenses. In addition, light and electron microscopic examinations revealed that telmisartan pre-treatment markedly ameliorated ischemia/reperfusion-induced renal tissue damage. It was concluded that telmisartan, through its antioxidant, anti-inflammatory and antiapoptotic effects, can be considered a potential candidate to protect against acute ischemia/reperfusion renal injury.

Protective effect of hemin against cadmium-induced testicular damage in rats.

The protective effect of hemin, the heme oxygenase-1 inducer, was investigated in rats with cadmium induced-testicular injury, in which oxidative stress and inflammation play a major role. Testicular damage was induced by a single i.p. injection of cadmium chloride (2mg/kg). Hemin was given for three consecutive days (40 micromol/kg/day, s.c.), starting 1 day before cadmium administration. Hemin treatment significantly increased serum testosterone level that was reduced by cadmium. Hemin compensated deficits in the antioxidant defense mechanisms (reduced glutathione, and catalase and superoxide dismutase activities), and suppressed lipid peroxidation in testicular tissue resulted from cadmium administration. Also, hemin attenuated the cadmium-induced elevations in testicular tumor necrosis factor-alpha and nitric oxide levels, and caspase-3 activity. Additionally, hemin ameliorated cadmium-induced testicular tissue damage observed by light and electron microscopic examinations. The protective effect afforded by hemin was abolished by prior administration of zinc protoporphyrin-IX, the heme oxygenase-1 inhibitor. It was concluded that hemin, through its antioxidant, anti-inflammatory and antiapoptotic effects, represents a potential therapeutic option to protect the testicular tissue from the detrimental effects of cadmium.

Overweight and obesity and their relation to dietary habits and socio-demographic characteristics among male primary school children in Al-Hassa, Kingdom of Saudi Arabia.

BACKGROUND: Several studies were carried out to study the prevalence of overweight and obesity among Saudi children, but those assessed the association between eating habits, socio-demographic differentials and obesity in these children are scarce. OBJECTIVES: To assess the magnitude of obesity and overweight among male primary schoolchildren and to find the possible association between obesity/overweight with dietary habits and socio-demographic differentials among them. STUDY DESIGN AND METHODS: A cross-sectional descriptive study including 1,139 Saudi male enrolled in the fifth and sixth grades in public primary schools in Al Hassa, KSA, through a multistage random sampling technique, submitted to interview using Youth and Adolescent Food Frequency Questionnaire, gathering data regarding dietary intake, some dietary habits, followed by anthropometric measurements with calculation of body mass index, the interpretation of which was based on using Cole's tables for standard definition of overweight and obesity. Socio-demographics data were collected through parental questionnaire form. Data analysis was carried out using SPSS 12 (SPSS Inc. Chicago, IL, USA), univariate as well as multivariate analyses were conducted. RESULTS: The age ranged from 10 to 14 years. The prevalence of overweight among the included subjects was 14.2% while obesity was 9.7%, more in urban, older age students, mothers of obese and overweight were less educated, more working. Missing and or infrequent intake of breakfast at home, frequent consumption of fast foods, low servings of fruits, vegetables, milk and dairy product per day, with frequent consumption of sweets/candy and carbonated drinks were all predictors of obesity and overweight among the included male schoolchildren. CONCLUSION: The prevalence of childhood obesity is escalating and approaching figures reported in the developed countries. Less healthy dietary habits and poor food choices may be responsible for this high prevalence.

Assessment of the relationship of hepatic enzymes with obesity and insulin resistance in adults in saudi arabia.

OBJECTIVES: This study was conducted to assess the relationship of hepatic enzymes and serum albumin to obesity and insulin resistance in adults in Saudi Arabia. METHODS: A comparative study of 136 Saudi adults, comprising of 68 obese and 68 non-obese was conducted. Anthropometric measurements, hepatic enzymes, serum albumin, blood glucose, serum insulin, lipid profile, and homeostasis model assessment of insulin resistance (HOMA IR) were measured. RESULTS: The study showed significantly higher levels of gamma glutamyl transpeptidase (GGT), alkaline phosphatase, fasting glucose, serum insulin, and HOMA IR p < 0.001, <0.004 < 0.005, <0.0001, <0.0001, among obese subjects. Hepatic enzymes correlated with both anthropometric measures (body mass index (BMI), and waist to hip ratio) and markers of insulin resistance (HOMA IR, insulin, and fasting glucose). However, the study found that GGT had the strongest associations. Significant inverse correlation was found between serum albumin and BMI, HOMA IR, and serum insulin, p< 0.01, <0.05, <0.01, respectively. CONCLUSION: Deranged liver functions, especially GGT, had the strongest correlations with obesity and HOMA IR. GGT might be a better marker of hepatic pathology associated with obesity and insulin resistance in Saudi adults with restricted alcohol intake. The results also propose that albumin metabolism might be altered in obesity.

Overweight and Obesity and their Association with Dietary Habits, and Sociodemographic Characteristics Among Male Primary School Children in Al-Hassa, Kingdom of Saudi Arabia.

OBJECTIVES: To assess the magnitude of obesity and overweight among male primary school children, and to find the possible association between obesity/overweight and dietary habits and sociodemographic differentials among them. STUDY DESIGN AND METHODS: A cross-sectional descriptive study, including 1139 Saudi male children enrolled in the 5(th) and 6(th) grades in public primary schools in Al Hassa, Kingdom of Saudi Arabia (KSA), was conducted. The test included a multistage random sampling technique, based on interview using Youth and Adolescent Food Frequency Questionnaire, gathering data regarding dietary intake, dietary habits, followed by anthropometric measurements with the calculation of body mass index (BMI), the interpretation of which was based on Cole's tables for the standard definition of overweight and obesity. Sociodemographic data were collected through a parental questionnaire from. Data analysis was performed using the SPSS 12 software (SPSS Inc. Chicago, IL, USA); both univariate and multivariate analyses were performed. RESULTS: The age of the school children ranged from 10-14 years. The prevalence of overweight among the subjects was 14.2%, while that of obesity was 9.7%; the prevalence was more in the urban, older age students. The mothers of obese and overweight children were less educated and more working. Missing and or infrequent intake of breakfast at home, frequent consumption of fast foods, low servings per day of fruits, vegetables, milk and dairy products, with frequent consumption of sweets/candy and carbonated drinks were all predictors of obesity and overweight among the schoolchildren studied. CONCLUSION: The prevalence of childhood obesity is escalating and approaching figures that have been reported till now from the developed countries. Less healthy dietary habits and poor selection of food may be responsible for this high prevalence.
