The effect of Mediterranean diet on inflammatory biomarkers and components of metabolic syndrome in adolescent girls.

BACKGROUND: The prevalence of obesity and metabolic syndrome (MetS) during childhood and adolescence is rising significantly worldwide. Previous studies have shown that following a healthy dietary pattern, like the Mediterranean diet (MD), might be an efficacious approach for the prevention and management of MetS during childhood. In the present study, we aimed to examine the effect of MD on inflammatory markers and components of MetS among adolescent girls with MetS. METHODS: This randomized controlled clinical trial was conducted on 70 girl adolescents with metabolic syndrome. Patients in the intervention group followed a prescribed MD, while participants in the control group received dietary advice according to the food pyramid. The length of intervention was 12 weeks. Participants' dietary intakes were evaluated using three 1-day food records throughout the study. Anthropometric measures, inflammatory markers, systolic and diastolic blood pressure, and hematological factors were assessed at the baseline and end of the trial. An intention-to-treat approach was taken into account for the statistical analysis. RESULTS: After 12 weeks, participants in the intervention group had lower weight (Ptime*group ≤ 0/001), body mass index (BMI) (Ptime*group ≤ 0/001), and waist circumference (WC) (Ptime*group ≤ 0/001) compared with those in the control group. In addition, MD resulted in a significantly reduced systolic blood pressure compared to the those in the control group (Ptime*group ≤ 0/001). In terms of metabolic variables, MD led to a significant decrease in fasting blood glucose (FBS) (Ptime*group ≤ 0/001), triglycerides (TG) (Ptime*group ≤ 0/001), low-density lipoprotein (LDL) (Ptime*group ≤ 0/001), homeostatic model assessment of insulin resistance (HOMA-IR) (Ptime*group = 0/02) and a meaningful increase in serum levels of high-density lipoprotein (HDL) (Ptime*group ≤ 0/001). In addition, adherence to the MD resulted in a significant reduction in serum levels of inflammatory markers including Interleukin 6 (IL-6) (Ptime*group = 0/02) and high-sensitivity C-reactive protein (hs-CRP) (Ptime*group = 0/02). However, no significant effect was seen on serum levels of tumor necrosis factor α (TNF-α) (Ptime*group = 0/43). CONCLUSION: Overall, the findings of the present study revealed that consumption of MD for 12 weeks resulted in a favorable effect on anthropometric measures, components of MetS, as well as on some inflammatory biomarkers.

Responses of some matrix metalloproteinases activities to an acute session of endurance exercise and electrical stimulation in induced myocardial infarction in Wistar rats.

OBJECTIVE: Myocardial infarction is the irreversible cell death of cardiac muscle that takes place after the blood flow is cut off to a specific region of the heart muscle. The molecular angiogenesis process that may follow after the incidence, due to any activity or its intensity, is unknown. The purpose of this research was to examine some of the matrix metalloproteinase (MMP) responses to an acute course of endurance exercise and electrical stimulation in induced myocardial infarcted Wistar rats. MATERIALS AND METHODS: In this experimental case-control study, 40 induced myocardial infarcted Wistar rats (8-week-old, mean weight 130±30 g) were randomly assigned into 4 conditions: endurance exercise, exercise + electrical stimulation, only electrical stimulation, and control group. The infarction was induced 24 hours after the subcutaneous injection of 150 mg/kg of Isoproterenol. The exercise and exercise plus electrical stimulation groups performed a session of endurance exercise on an animal treadmill, at 20 m/min for one hour. The electrical stimulation was delivered by foot shock, set with the intensities of 0.5 mA for 20 minutes. Immediately after the cessation of the treatment protocol, MMP1, MMP2, and MMP9 were measured by the ELISA method. Data analysis was performed by using Two-way ANOVA and significance was set at α = 0.05. RESULTS: One session of endurance exercise or electric stimulation, or their combination, had no significant effect on the level of MMPs. CONCLUSIONS: One session of acute endurance exercise, stimulation, or their combination, elicited no significant effect on the level of MMPs of artificially induced myocardial infarcted Wistar rats.

A Systematic Review and Meta-analysis of the Medical Error Rate in Iran: 2005-2019.

BACKGROUND AND OBJECTIVES: Medical errors (MEs) are one of the main factors affecting the quality of hospital services and reducing patient safety in health care systems, especially in developing countries. The aim of this study was to determine the rate of ME in Iran. METHODS: This is a systematic literature review and meta-analysis of extracted data. The databases MEDLINE, EMBASE, Scopus, Cochrane, SID, Magiran, and Medlib were searched in Persian and English, using a combination of medical subject heading terms ("Medical Error" [Mesh] OR "Medication error" [Mesh] OR "Hospital Error" AND ("Iran" [Mesh]) for observational and interventional studies that reported ME rate in Iran from January 1995 to April 2019. We followed the STROBE checklist for the purpose of this review. RESULTS: The search yielded a total of 435 records, of which 74 articles were included in the systematic review. The rate of MEs in Iran was determined as 0.35%. The rates of errors among physicians and nurses were 31% and 37%, respectively. The error rates during the medication process, including prescription, recording, and administration, were 31%, 27%, and 35%, respectively. Also, incidence of MEs in night shifts was higher than in any other shift (odds ratio [OR] = 38%; 95% confidence interval [CI]: 31%-45%). Moreover, newer nurses were responsible for more errors within hospitals than other nurses (OR = 57%; 95% CI: 41%-80%). The rate of reported error after the Health Transformation Plan was higher than before the Health Transformation Plan (OR = 40%; CI: 33%-49% vs OR = 30%; CI: 25%-35%). CONCLUSION: This systematic review has demonstrated the high ME rate in Iranian hospitals. Based on the error rate attributed solely to night shifts, more attention to the holistic treatment process is required. Errors can be decreased through a variety of strategies, such as training clinical and support staff regarding safe practices and updating and adapting systems and technologies.
