Impact of the Level of Adherence to Mediterranean Diet on the Parameters of Metabolic Syndrome: A Systematic Review and Meta-Analysis of Observational Studies

High adherence to the Mediterranean diet (MD) has been associated with a lower prevalence of Metabolic Syndrome (MetS). The present study aimed to investigate the impact of MD adherence on parameters of MetS. A systematic literature search was performed in PubMed, Cochrane Central Registry of Clinical Trials (CENTRAL), Scopus, EMBASE, Web of Science and Google Scholar databases. Observational studies that recorded adherence to MD and components/measures of the MetS, such as waist circumference (WC), blood pressure (BP), fasting blood glucose (FBG), high-density lipoprotein (HDL) cholesterol and triglycerides (TG), were included in this study. A total of 58 studies were included in our study. WC and TG were significantly lower in the high adherence MD group (SMD: −0.20, (95%CI: −0.40, −0.01), SMD: −0.27 (95%CI: −0.27, −0.11), respectively), while HDL cholesterol was significantly higher in the same group (SMD: −0.28 (95%CI: 0.07, 0.50). There was no difference in FBG and SBP among the two groups (SMD: −0.21 (95%CI: −0.54, 0.12) & SMD: −0.15 (95%CI: −0.38, 0.07), respectively). MD may have a positive impact on all parameters of MetS. However, further research is needed in this field.     

Evaluation of the impact of Exomite Pro™ on Varroa mite (Varroa destructor) populations and honeybee (Apis mellifera) colonies: efficacy,side effects and residues

In this research, we examined the application of thymol-based powder, directly over the top of the brood frames in colonies with different population in a 2-year study. The efficacy against mites, the side effects on bees and the contamination of honey were studied comparably to thymol-based gel treatment. In one-store colonies, thymol-based powder treatment gave average efficacy 64.5 % and did not differ significantly from thymol-based gel treatment (65.4 %). The natural mortality in control colonies was 41.4 % and the corrected efficacy (E _T) during 2 years was 39.4 and 40.9 %, respectively. In two-store bee colonies, the application of thymol-based powder on top of each hive body gave higher E _T (45,4 %) than on top of the double body hive (40.4 %), without statistically significant differences. The average concentration of thymol residues in honey 24 days after the application was 368 and 1,119 μg kg^?1 for the honey of colonies treated with thymol-based powder and thymol-base gel, respectively.

Liver steatosis is an independent risk factor for treatment failure in patients with chronic hepatitis C

OBJECTIVES: Hepatic steatosis is a common feature of chronic hepatitis C. The purpose of this study was to determine factors related to the presence of steatosis and to define the role of steatosis in the response to antiviral treatment in chronic hepatitis C patients. METHODS: We retrospectively analysed all patients with chronic hepatitis C treated in a 5 year period in our department. Patients were included in the study only if a pretreatment liver biopsy specimen was available for evaluation. All patients treated either with interferon in combination with ribavirin, or with pegylated interferon in combination with ribavirin were included irrespectively of their response (early, end of treatment and/or sustained) to antiviral therapy. RESULTS: A total of 116 patients with chronic hepatitis C were included in the study with a mean age of 45.5 +/- 14.1 years. Steatosis was present in 52 patients (44.8%). On univariate analysis age, P = 0.04 and body mass index > or = 25, P = 0.004 were correlated with the presence of steatosis and on multivariate analysis only body mass index > or = 25, P = 0.032. Advanced fibrosis was not found associated with steatosis. Sixty patients out of 116 (51.7%) had sustained virological response (SVR). In particular 42 out of 64 patients with no steatosis (65.6%) had SVR compared to 20 out of 52 patients (38.4%) with any degree of steatosis (P = 0.009). Patients with genotype 2 or 3 had a more favourable outcome compared to patients with 1 or 4 genotypes, 63.2% vs 49.2%, P = 0.032. Also increased age (P = 0.0001), gamma glutamyltransferase (GGT) (P = 0.029), no history of intravenous drugs use (P = 0.001) and advanced fibrosis on pretreatment biopsy (P = 0.046) were correlated with treatment failure. On multivariate analysis significant independent association with SVR was found with the presence of steatosis on pretreatment biopsy (P = 0.004), increased GGT (P = 0.005) and genotype (P = 0.017). CONCLUSION: Steatosis in the liver biopsy performed before the beginning of antiviral treatment was found to be associated only to the body mass index of the patients and to be a strong independent factor for treatment failure.     

The combination of Everolimus with Verapamil reduces ovarian weight and vascular permeability on ovarian hyperstimulation syndrome: a preclinical experimental randomized controlled study

The efficacy of pathways inhibition and the combined effect of Everolimus (mTOR inhibitor) and Verapamil (CYP3A inhibitor) in ovarian hyperstimulation syndrome (OHSS) need to be tested. Therefore, the impact of a leucotriene receptor antagonist, an anticoagulant, a GnRH antagonist as well as Everolimus plus Verapamil (at various doses and days of administration) on an OHSS rat model was tested. Sixty three female Wistar rats were randomly divided into seven groups. The control group received saline, while the OHSS group received rec-FSH for four consecutive days. The other five groups received rec-FSH for four days and Montelukast daily, Heparin daily, GnRH antagonist daily, Everolimus plus Verapamil in the last two days (half days group) and Everolimus plus Verapamil (half dose group) daily, respectively. All groups received also hCG at the fifth day. Significantly reduced ovarian weight was observed in the Everolimus plus Verapamil groups (half days and half-dose groups) and the Montelukast group compared to the OHSS group (p?=?0.001 and p?=?0.001, respectively). The vascular permeability was significantly reduced in the Everolimus plus Verapamil group (half dose group) and the GnRH antagonist group compared to the OHSS group (p?p?=?0.011, respectively). However, estradiol and progesterone levels did not differ significantly between the groups. Studying the inhibition of different pathways, we concluded that the co-administration of Everolimus and Verapamil (at half dose) is beneficial for reducing ovarian weight and vascular permeability in an OHSS animal model.
