Background The coronavirus disease 2019 (COVID-19) patients with diabetes mellitus (DM) are at high risk of fatal outcomes. This meta-analysis quantifies the prevalence of mortality among (1) diabetic and (2) non-diabetic, and (3) the prevalence of DM, in hospitalized COVID-19 patients. Methods Published studies were retrieved from four electronic databases (PubMed, Embase, Scopus, and medRxiv) and appraised critically utilizing the National Heart, Lung, and Blood Institute’s tool. Meta-analyses were performed using the random-effects model. The measures of heterogeneity were ascertained by I- squared ( I 2 ) and Chi-squared ( Chi 2 ) tests statistics. Predictors of heterogeneity were quantified using meta-regression models. Results Of the reviewed 475 publications, 22 studies (chiefly case series (59.09 %)), sourcing data of 45,775 hospitalized COVID-19 patients, were deemed eligible. The weighted prevalence of mortality in hospitlized COVID-19 patients with DM (20.0 %, 95 % CI: 15.0–26.0; I 2 , 96.8 %) was 82 % (1.82-time) higher than that in non-DM patients (11.0 %, 95 % CI: 5.0–16.0; I 2 , 99.3 %). The prevalence of mortality among DM patients was highest in Europe (28.0 %; 95 % CI: 14.0–44.0) followed by the United States (20.0 %, 95 % CI: 11.0–32.0) and Asia (17.0 %, 95 % CI: 8.0–28.0). Sample size and severity of the COVID-19 were associated (p < 0.05) with variability in the prevalence of mortality. The weighted prevalence of DM among hospitalized COVID-19 patients was 20 % (95 % confidence interval [CI]: 15–25, I 2 , 99.3 %). Overall, the quality of the studies was fair. Conclusions Hospitalized COVID-19 patients were appreciably burdened with a high prevalence of DM. DM contributed to the increased risk of mortality among hospitalized COVID-19 patients compared to non-DM patients, particularly among critically ill patients.

Women in the Middle East and North Africa (MENA) region are burdened with several risk factors related to gestational diabetes mellitus (GDM) including overweight and high parity. We systematically reviewed the literature and quantified the weighted prevalence of GDM in MENA at the regional, subregional, and national levels. Studies published from 2000 to 2019 reporting the prevalence of GDM in the MENA region were retrieved and were assessed for their eligibility. Overall and subgroup pooled prevalence of GDM was quantified by random-effects meta-analysis. Sources of heterogeneity were investigated by meta-regression. The risk of bias (RoB) was assessed by the National Heart, Lung, and Blood Institute’s tool. One hundred and two research articles with 279,202 tested pregnant women for GDM from 16 MENA countries were included. Most of the research reports sourced from Iran (36.3%) and Saudi Arabia (21.6%), with an overall low RoB. In the 16 countries, the pooled prevalence of GDM was 13.0% (95% confidence interval [CI], 11.5–14.6%, I2, 99.3%). Nationally, GDM was highest in Qatar (20.7%, 95% CI, 15.2–26.7% I2, 99.0%), whereas subregionally, GDM was highest in Gulf Cooperation Council (GCC) countries (14.7%, 95% CI, 13.0–16.5%, I2, 99.0%). The prevalence of GDM was high in pregnant women aged ≥30 years (21.9%, 95% CI, 18.5–25.5%, I2, 97.1%), in their third trimester (20.0%, 95% CI, 13.1–27.9%, I2, 98.8%), and who were obese (17.2%, 95% CI, 12.8–22.0%, I2, 93.8%). The prevalence of GDM was 10.6% (95% CI, 8.1–13.4%, I2, 98.9%) in studies conducted before 2009, whereas it was 14.0% (95% CI, 12.1–16.0%, I2, 99.3%) in studies conducted in or after 2010. Pregnant women in the MENA region are burdened with a substantial prevalence of GDM, particularly in GCC and North African countries. Findings have implications for maternal health in the MENA region and call for advocacy to unify GDM diagnostic criteria.Systematic Review RegistrationPROSPERO CRD42018100629

The aim of this study was to study the role of vitamin D containing supplements in the risk of cesarean section (CS), a common complication in gestational diabetes mellitus (GDM) patients. An additional objective was to assess the risk of developing pre-eclampsia, preterm delivery, macrosomia, and polyhydramnios in these participants. Various electronic databases were searched for double-blinded parallel-arm randomized controlled trials that reported the incidence of CS in adult, non-insulin treated GDM patients who received vitamin D and placebo in different treatment arms, respectively. Next, each eligible trial’s risk of bias was assessed, and the effects of the above interventions on the respective outcomes were compared meta-analytically across the trials. This review included five Iranian trials sourcing data from nearly 380 participants. The risk of bias in the trials was primarily low. In contrast to the placebo group, the risk of CS [risk ratio (RR): 0.61, p=0.002, 95% confidence interval (CI): 0.44,0.83; I 2 =0%, p-value of Cochrane’s Q: 0.373) and macrosomia (RR: 0.31, p=0.006, 95% CI: 0.13,0.72; I 2 =0%, p-value of Cochrane’s Q: 0.935] was less in the vitamin D supplemented group. The remaining outcomes did not differ between the intervention groups. The antenatal use of vitamin D containing supplements in non-insulin treated GDM patients might reduce the risk of CS and macrosomia.

To determine human bocavirus-1 (HBoV1) infection characteristics in young Australian children. Data were from the Observational Research in Childhood Infectious Diseases (ORChID) study, a Brisbane, Australia–based birth cohort of healthy, term, newborns followed prospectively for 2 years. Parents recorded daily symptoms, maintained an illness-burden diary, and collected weekly nasal swabs, which were tested for 17 respiratory viruses, including HBoV1, by real-time polymerase chain reaction (PCR) assays. Main outcomes measured were infection incidence, risk factors, symptoms, and healthcare use. One hundred fifty-eight children in the ORChID cohort provided 11,126 weekly swabs, of which 157 swabs were HBoV1 positive involving 107 incident episodes. Co-detections were observed in 65/157 (41.4%) HBoV1-positive swabs (or 41/107 [38.3%] infection episodes), principally with rhinovirus. Shedding duration was 1 week in 64.5% of episodes. The incidence of HBoV1 infections in the first 2 years of life was 0.58 episodes per child-year (95% confidence interval [CI] 0.47–0.71), including 0.38 episodes per child-year (95% CI 0.30–0.49) associated with respiratory symptoms. Recurrent episodes occurred in 18/87 (20.7%) children following their primary infection. In the first 2 years of life, incidence of HBoV1 episodes increased with age, during winter and with childcare attendance. Overall, 64.2% of HBoV1 episodes were symptomatic, with 26.4% having healthcare contact. Viral load estimates were higher when children were symptomatic than when asymptomatic (mean difference = 3.4; 95% CI 1.0–5.7 PCR cycle threshold units). After age 6 months, HBoV1 is detected frequently in the first 2 years of life, especially during winter. Symptoms are usually mild and associated with higher viral loads.

Evidence suggests, continuous mode ultrasound improves joint motion. However, little is known if it increases shoulder joint kinesis in primary adhesive capsulitis patients. →What this article adds: In primary adhesive capsulitis, the current evidence regarding the continuous mode of ultrasound therapy and the improvement of shoulder joint mobility remains inconclusive. New multicentric clinical trials with high statistical power and low risk of bias are needed to generate constructive evidence in this context.

<b><i>Background:</i></b> This study aims to contrast the side effects of treatment with sodium-glucose cotransporter-2 inhibitors (SGLT2i) and placebo in insulin-treated adult type 1 diabetes mellitus (T1DM) patients. <b><i>Methods:</i></b> Double-blinded randomized controlled trials that compare the above outcome were searched in electronic databases. Next, the risk of bias in eligible studies was assessed, and comparable outcomes were compared by a random-effects meta-analysis. <b><i>Results:</i></b> Seven eligible papers comprising about 3,900 participants were studied. All trials suffered from an unclear risk of detection bias and performance bias. In comparison with the placebo group, the risk of genital infection (RR = 3.22, <i>p</i> &#x3c; 0.001, 95% CI 2.31–4.49, <i>I</i>² = 0%) and diabetic ketoacidosis (RR = 2.66, <i>p</i> = 0.002, 95% CI 1.45–4.89, <i>I</i>² = 0%) was higher in the SGLT2i-treated group. <b><i>Conclusion:</i></b> SGLT2i treatment increased the risk of genital infection and diabetic ketoacidosis in adult insulin-treated T1DM patients.

Background and Purpose: The dapagliflozin’s safety profile in insulin-treated adult type-1 diabetes mellites (T1DM) patients remains poorly explored. Therefore, this systematic review and meta-analysis compared the risk of all-cause side effects, study discontinuation of participants due to side effects, urinary tract infection (UTI), diabetic ketoacidosis, and hypoglycemia between dapagliflozin 10 mg and dapagliflozin 5 mg, dapagliflozin 10 mg and placebo, and dapagliflozin 5 mg and placebo.Materials and Methods: Parallel-arm randomized controlled trials juxtaposing the above outcomes between the afore-mentioned interventions were eligible for inclusion in this study and were searched in PubMed, Embase, and Scopus. Utilizing the Cochrane tool, the risk of bias was assessed in the recruited trials. Finally, by random-effect meta-analysis, each outcome was compared among the above interventions, and the risk ratio was estimated.Results: Four trials of varying length (1-52 weeks) sourcing data from almost 1760 participants from about 32 nations were reviewed. Overall, the trials had a low or unclear risk of bias, and only one was at a high risk of bias.  Compared to the placebo, the risk of side effects was higher in those treated with dapagliflozin 5 mg (RR=1.10; 95% CI=1.02-1.18; p=0.014; I2=0%). UTI risk was less with the 10mg dapagliflozin than its lower dose (RR=0.50; 95% CI=0.32-0.79; p-value=0.003; I2=0%). All the remaining comparisons were statistically not significantly different between the juxtaposed intervention pairs.Conclusion: In contrast to placebo, dapagliflozin 5mg increased the risk of overall adversities in insulin-treated type-1 diabetes, and dapagliflozin 10 mg had a reduced risk of UTI than its 5mg preparation.

<b><i>Aims:</i></b> To date, it is largely unknown how body mass index (BMI), gestational weight (GW), and stored vitamin D (25(OH)D) levels change in the vitamin D-supplemented gestational diabetes mellitus (GDM) patients, irrespective of their pre-pregnancy BMI. Therefore, to study this association, a prospective systematic review and meta-analysis protocol is proposed here. <b><i>Methods:</i></b> Primarily, different databases (PubMed, Embase and Scopus) will be searched (without any limitation to date or language) for randomised parallel-arm trials comparing GW, BMI and stored vitamin D level in the body among GDM patients who were supplemented and not supplemented with vitamin D, besides their conventional GDM care. The study selection process and the consecutive risk of bias assessment will adhere to the PRISMA 2009 flow chart and the Cochrane collaboration’s guideline, respectively. These interventions’ effect on the respective outcomes will be compared by meta-analysis (along with an assessment of the statistical heterogeneity) when comparable data will be available from at least 4 studies. Subgroup analysis and Egger’s meta-regression will follow if an adequate number of trials are available. Narrative reporting will be considered when a quantitative comparison is not feasible for any of the outcomes. <b><i>Conclusion:</i></b> The proposed review aims to compare the BMI, GW, and 25(OH)D levels in the blood between the vitamin D supplemented and not supplemented GDM patients.
