Background: Gastrointestinal and cardiovascular diseases are considered to be among the consequences of shiftwork in nursing staff. This study aimed to investigate the prevalence of gastrointestinal and cardiovascular diseases and model their consequences in nurses.Methods: This cross-sectional study was conducted in seven hospitals in Khuzestan Province in 2020. The participants of the study were 652 nurses. The data were collected through a questionnaire developed by Choobineh et al. The questionnaire included demographic questions and shift work related health effects. The modeling was performed via logistic regression in SPSS 22.Results: The prevalence of gastrointestinal (52.53% vs. 35.19%) and cardiovascular (35.02% vs. 22.22%) disorders were significantly higher in shift working nurses than in day-working ones (P<0.05). In addition to shiftwork, work experience, working hours per week, and hospital wards significantly affected the prevalence of gastrointestinal disorders in nurses (P<0.05). The shiftwork system, age, work experience, and working hours per week had significant positive correlations with the prevalence of cardiovascular diseases in nurses (P<0.05). Furthermore, the chance of having gastrointestinal and cardiovascular diseases was 2.73 and 2.08 times more in shift-working nurses than in day-working ones, respectively.Conclusion: Beside the shift work, the findings of the study indicated the important role of other risk factors, such as age, work experience, working hours per week, and hospital wards for the prevalence of gastrointestinal and cardiovascular diseases in nurses. Therefore, it is recommended that these factors should be taken into account while trying to manage, control, and reduce such negative consequences in nurses.

Background: Heart failure (HF) is a clinical disorder and Zinc is an important cofactor in regulating oxidative status.The present study aimed to determine the mean concentration of serum zinc in patients with HF.
Methods: PubMed, Embase, Scopus, and Web of Science were used in the present systematic review and meta-analysis to find relevant cross-sectional studies up to 1st January 2020. A random-effects model was used to pool the effect size (ES) and 95 % confidence intervals (CI). In addition, meta-regression analysis was performed to find the sources of statistical heterogeneity among the studies.
Results: Our meta-analysis of 1358 HF patients indicated that their mean serum zinc concentration was 66.24 µg/dl (95 % CI: 59.16, 73.33). In sub-analysis, the mean concentration was 75.04 µg/dl and 52.90 µg/dl in patients < 65 years and > 65 years old, respectively. Subgroup analysis by geographical region showed that mean serum zinc was 70.70 µg/dl, 69.08 µg/dl and 60.91 µg/dl in HF patients from Europe, America, and Asia, respectively. Meta-regression analysis indicated a reduction of 1.42 µg/dl in serum zinc per each year of aging.
Conclusion: In summary, our meta-analysis indicates that serum zinc concentrations have a narrow range in HF patients worldwide that declines with age and varies with geographical region. Additionally, serum zinc concentrations are lower in HF patients, specifically in the elderly.

AbstractBackground: Vitamin D deficiency is implicated in a wide rangeof pathological situations including cardiovascular diseases.This study aimed to investigate the association between serum25-hydroxy vitamin D (25(OH)D) and risk factors of metabolicsyndrome and cardiovascular diseases.Methods: The cross-sectional study was conducted on 169adults (88 males, 81 females) aged 19-52 years living in Shiraz,Iran. Anthropometric characteristics and blood pressure weremeasured using standard methods. Blood samples were collectedin fasting state for determination of blood glucose, lipids, and25(OH)D. Data were analyzed with one-way analysis of varianceand linear regression using SPSS software.Results: Serum 25(OH)D concentrations were considerablyhigher in males. One third of females had vitamin D deficiency(25(OH)D <10 ng/ml) while one third of males exhibited25(OH)D levels >50 ng/ml. In males, systolic and diastolicblood pressure, triglycerides, and metabolic syndrome scoreincreased and high-density lipoprotein (HDL) cholesteroldecreased across tertiles of serum 25(OH)D. On the contrary,in females body mass index (BMI) and metabolic syndromescore decreased and HDL cholesterol increased across tertilesof 25(OH)D. Linear regression, after controlling for confoundingfactors, showed that diastolic blood pressure (B=0.07; 95% CI:0.02, 0.11; P=0.006), triglycerides (B=0.54; 95% CI: 0.22, 0.85;P=0.001), and metabolic syndrome score (B=0.01; 95% CI: 0.001,0.01; P=0.02) positively and HDL cholesterol (B=-0.05; 95% CI:-0.09, -0.01; P=0.02) inversely associated with tertiles of 25(OH)D concentrations in males. In contrast, BMI (B=-0.06; 95% CI:-0.11, -0.02; P=0.01), waist circumference (B= -0.12; 95% CI:-0.23, -0.01; p=0.04), and metabolic syndrome score (B=-0.02;95% CI:-0.03, -0.01; P=0.01) were inversely and HDL-C (B=0.16;95% CI: 0.02, 0.31; P=0.02) positively associated with 25(OH)D tertiles in females.Conclusion: The results suggest that both low and uppernormal levels of 25(OH)D are associated with increased risk ofcardiovascular diseases and metabolic syndrome.
