This study was conducted to investigate the effect of the prepregnancy BMI on the risk of gestational diabetes mellitus (GDM). Five electronic databases, including PubMed, Scopus, Embase, Web of Science, and Google Scholar, were searched for literature published until 1 January 2018. The two-stage, random effect meta-analysis was performed to compare the dose-response relationship between BMI and GDM.As well as studies with categorized BMI, studies that treat BMI as a continuous variable were analysed. A total of 33 observational studies with an overall sample size of 962 966 women and 42 211 patients with GDM were included in analysis. The pooled estimate of GDM risk in the underweight, overweight, and obese pregnant women was 0.68, 2.01, and 3.98 using the adjusted OR and 0.34, 1.52, and 2.24 using the adjusted RR. The GDM risk increased 4% per unit of increase in BMI with both the crude and adjusted OR/RR models. Also, the risk of GDM increased 19% with the crude model and 14% with the adjusted model. The existence of dose-response relationship between the pre-pregnancy BMI and GDM can strengthen the scientific background for vigorous public health interventions for the control of pre-pregnancy BMI as well as the weight gain during pregnancy.

Clonal expansion of fluconazole resistant (FLZ-R) Candida parapsilosis isolates is increasingly being identified in many countries, while there is no study exploring the antifungal susceptibility pattern, genetic diversity, and clinical information for Iranian C. parapsilosis blood isolates. Candida parapsilosis species complex blood isolates (n = 98) were recovered from nine hospitals located in three major cities, identified by MALDI-TOF MS, and their genetic relatedness was examined by AFLP fingerprinting. Antifungal susceptibility testing followed CLSI-M27-A3 and ERG11, MRR1 and hotspots 1/2 (HS1/2) of FKS1 were sequenced to assess the azole and echinocandin resistance mechanisms, respectively. Ninety-four C. parapsilosis and four Candida orthopsilosis isolates were identified from 90 patients. Only 43 patients received systemic antifungal drugs with fluconazole as the main antifungal used. The overall mortality rate was 46.6% (42/90) and death mostly occurred for those receiving systemic antifungals (25/43) relative to those not treated (17/47). Although, antifungal-resistance was rare, one isolate was multidrug-resistant (FLZ = 16 µg/ml and micafungin = 8 µg/ml) and the Arastehfar et al. Candida parapsilosis Blood Isolates Typing infected patient showed therapeutic failure to FLZ prophylaxis. Mutations causing azole and echinocandin resistance were not found in the genes studied. AFLP revealed five genotypes (G) and G1 was the main one (59/94; 62.7%). Clinical outcome was significantly associated with city (P = 0.02, α <0.05) and Mashhad was significantly associated with mortality (P = 0.03, α <0.05). Overall, we found a low level of antifungal resistance for Iranian C. parapsilosis blood isolates, but the noted MDR strain can potentially become the source of future infections and challenge the antifungal therapy in antifungal-naïve patients. AFLP typing results warrants confirmation using other resolutive typing methods.

Background Considering the lifelong dietary restriction in celiac patients, it is important to assess the diet quality in these patients. Hence, this study aimed to investigate the diet quality in adult celiac patients and compare it with that of the non-celiac people. Methods In the present cross-sectional study, 130 celiac patients were selected from the celiac disease (CD) registry database of East Azerbaijan province, Iran. Non-celiac people (n = 464) was selected from the major lifestyle promotion project conducted in the East Azerbaijan district. The dietary intake data was obtained by an 80-item semi-quantitative food frequency questionnaire. Diet quality was assessed using the healthy eating index-2015 (HEI-2015). Results The mean total HEI score was significantly higher in the celiac group compared with the non-celiac people (P < 0.001) and 68.5% of non-celiac people and 17.4% of celiac patients had poor diet quality. After adjusting for confounding factors, the mean score of total HEI in adherents to gluten-free diet (GFD) was significantly higher compared with non-adherents (P = 0.007). Conclusions Although the mean total HEI score was higher in celiac patients compared with the non-celiac people, about 17.5% of patients had poor diet quality and the scores of whole grains and dairy products group were very low in our population. Accordingly, it seems that educational programs should be held for the celiac patients and non-celiac people to increase their nutritional literacy and enable them to select healthy gluten-free alternatives.
