Objectives Hospital-acquired infections (HAIs) are significant problems as public health issues which need attention. Such infections are significant problems for society and healthcare organizations. This study aimed to carry out a systematic review and a meta-analysis to analyze the prevalence of HAIs globally. Methods We conducted a comprehensive search of electronic databases including EMBASE, Scopus, PubMed and Web of Science between 2000 and June 2021. We found 7031 articles. After removing the duplicates, 5430 studies were screened based on the titles/ abstracts. Then, we systematically evaluated the full texts of the 1909 remaining studies and selected 400 records with 29,159,630 participants for meta-analysis. Random-effects model was used for the analysis, and heterogeneity analysis and publication bias test were conducted. Results The rate of universal HAIs was 0.14 percent. The rate of HAIs is increasing by 0.06 percent annually. The highest rate of HAIs was in the AFR, while the lowest prevalence were in AMR and WPR. Besides, AFR prevalence in central Africa is higher than in other parts of the world by 0.27 (95% CI, 0.22–0.34). Besides, E. coli infected patients more than other micro-organisms such as Coagulase-negative staphylococci, Staphylococcus spp. and Pseudomonas aeruginosa. In hospital wards, Transplant, and Neonatal wards and ICU had the highest rates. The prevalence of HAIs was higher in men than in women. Conclusion We identified several essential details about the rate of HAIs in various parts of the world. The HAIs rate and the most common micro-organism were different in various contexts. However, several essential gaps were also identified. The study findings can help hospital managers and health policy makers identify the reason for HAIs and apply effective control programs to implement different plans to reduce the HAIs rate and the financial costs of such infections and save resources.
Aims: Following carnitine administration a decrease in plasma levels of triglyceride (TG) and increase in total high-density lipoprotein cholesterol (HDL-C) has been reported. Our hypothesis was that it also improves the HDL2/HDL3 ratio, symptomatic intradialytic hypotension, and anemia in hemodialysis (HD) patients. Methods: Forty HD patients with a mean (± SD) age of 53 ± 13 years were treated with 500 mg/day carnitine taken orally for 2 months. Patients were used as their own controls (before treatment). Lipid and lipoproteins were determined by Alcyon Abbott autoanalyzer. HDL subclasses were measured by magnesium precipitation after fractionation with dextran sulfate. Hemoglobin, hematocrit and serum albumin were measured by standard methods. The results were analyzed by SPSS 11.05. Results: We found a significant decrease in serum TG (2.22 ± 0.99 vs. 1.93 ± 1.07 mmol/l, p < 0.01) and VLDL-C (0.93 ± 0.36 vs. 0.81 ± 0.34 mmol/l, p = 0.01) and a marked increase in HDL-C (0.9 ± 0.16 vs. 1.06 ± 0.24 mmol/l, p < 0.05), HDL2-C (0.17 ± 0.06 vs. 0.27 ± 0.14 mmol/l, p < 0.05) and albumin (37 ± 4 vs. 42 ± 5 g/l, p = 0.01) levels. The serum levels of total cholesterol (4.61 ± 0.89 vs. 4.5 ± 0.95 mmol/l, p = 0.1), LDL-C (2.78 ± 0.85 vs. 2.6 ± 0.89 mmol/l, p > 0.05), HDL3-C (0.73 ± 0.1 vs. 0.79 ± 0.17 mmol/l, p > 0.05), hemoglobin, hematocrit, and intradialytic blood pressure did not change after the treatment. Conclusion: Treatment with 500 mg/day carnitine taken orally for 2 months reduces serum levels of TG and VLDL-C, and increases HDL-C, HDL2-C and albumin in HD patients.
Background: Needlestick injuries (NSIs) are one of the most serious occupational hazards for healthcare workers (HCWs). Aims: The aim of this study was to evaluate the incidence and causes of NSIs globally. Methods: A systematic review and meta-analysis of data from January 2000 to May 2020 collected from Scopus, PubMed, Embase, Web of Science, and Google Scholar. The Newcastle–Ottawa Scale was used to assess the quality of the included articles. The data obtained were analysed by R version 3/5/0, and 113 articles were retrieved. Results: There were 113 studies with a total of 525 798 HCWs. The incidence of NSIs was 43%. Africa had the highest rate of these injuries of 51%, and the World Health Organization (WHO) African Region had the highest incidence among WHO regions of 52%. Women were more frequently affected by NSIs than men. Hepatitis C virus infection was the disease most commonly transmitted via NSIs (21%). The highest rates of NSIs according to causes, devices, hospital locations, occupations and procedures were for recapping of needles, needles, general wards, nurses and waste disposal, respectively. Conclusion: The incidence of NSIs is gradually decreasing. The findings of this study can contribute to improving the decision-making process for reducing NSIs in HCWs.
Abstract:Background: The role of adiponectin in the development of cardiac disease remains less clear than in metabolic disorders. While some studies indicated that low adiponectin levels were associated with cardiovascular disease, not all studies have been able to show such association. Adiponectin levels may infl uence the development of chronic heart failure, but the epidemiological data are somewhat complex. Thus, the aim of this study was a survey of relationship between serum Adiponectin and prognosis of patients with heart failure in Iran. Methods and materials:In this cohort study, we evaluated 96 chronic heart failure patients. Patients with systolic dysfunction that was defi ned as left ventricular Ejection Fraction (EF) ≤40 % or had a history of heart failure were included in the study. At the baseline visit, all patients were examined by a physician and the following information was obtained: medical history, physical examination, New York Heart Association (NYHA) classifi cation. After the fi rst evaluation, analyses of adiponectin, Pro BNP, creatinine and uric acid were performed. Then the patients were followed up for a median of 12 months. Results: There was a signifi cant relationship between the mean adiponectin and Pro BNP levels and the ejection fraction (p=0.003 and p=0.003 respectively). Higher levels of adiponectin and Pro BNP were associated with a lower ejection fraction and there were no such associations between creatinine and uric acid levels. There was a signifi cant association between the functional capacity as assessed by NYHA class and the mean of adiponectin and uric acid, these means that higher levels of adiponectin and uric acid were associated with a higher functional class in patients with CHF (p=0.03 and p=0.04 respectively). During a 12 month follow-up, 22 (22.9 %) patients died. In subjects who died, the baseline mean plasma adiponectin and Pro BNP levels were higher compared to those who were alive at the follow-up and these difference were statistically signifi cant (19±7.4 vs.15.8±8 ng/ml and 9520±10249 vs. 3172±4628 ng/L p=0.000). Conclusion:The present study demonstrated that the plasma adiponectin level increased according to the severity of heart failure and also there was such relationship between Pro BNP and heart failure (Tab. 3, Ref. 35).
