Observational Study
Health-related quality of life in type 1 diabetes mellitus pediatric patients and their caregivers in Spain: an observational cross-sectional study.
Objectives: This study assessed the health-related quality of life (HRQOL) of pediatric patients with type 1 diabetes mellitus (T1DM) and their caregivers. Methods: CHRYSTAL was an observational cross-sectional study conducted in Spain in 2014 on 275 patients under 18 years old diagnosed with T1DM. Patient/caregiver pairs were stratified by patients' HbA1c level (≥7.5% versus <7.5%) and by presence or absence of T1DM complications and/or comorbidities. ⋯ EQ-5D scales showed significant moderate correlation between EQ-5D-Y and EQ-5D-3L proxy VAS score (rho = 0.45; p < .001). Conclusions: Patients with few complications and controlled HbA1c reported a relatively high HRQOL. The results suggest that parent-proxy EQ-5D ratings are valid for use as part of an overall health outcomes assessment in clinical studies of T1DM in pediatric patients.

Objectives: The study aimed to investigate risk factors for venous symptoms in Russian patients with chronic venous disease (CVD). Methods: Data on 487 patients with CVD aged 18 years and more were extracted from the database of a cross-sectional population-based study on the prevalence of CVD in a rural settlement. Risk factors for venous symptoms were calculated by multiple regression analysis. ⋯ Superficial venous reflux is a predictor only for venous pain (HR 2.4, p < .01). Conclusions: This study presents independent risk factors for venous symptoms in CVD patients. It demonstrates that different symptoms are associated with different factors.

Randomized Controlled Trial Multicenter Study Comparative Study
Patient-reported outcomes from a randomized, crossover trial comparing a pen injector with insulin degludec versus a pen injector with insulin glargine U100 in patients with type 2 diabetes.
Objective: Type 2 diabetes (T2D) is associated with insulin resistance and deteriorated glycemic control that can be restored with insulin injections. Choice of insulin pen injector may affect complexity, adherence, efficacy of treatment and health-related quality of life. We describe detailed patient-reported outcomes (PROs) on treatment impact and preference comparing insulin degludec (degludec) using FlexTouch1 versus insulin glargine U100 (glargine U100) with SoloStar2 pen injector. ⋯ Significantly more were "not at all bothered" by device discomfort (74.3 vs. 54.1%), whereas device size (83.8 vs. 80.0%) or public use (69.9 vs. 60.7%) were numerically in favor of FlexTouch. Significantly more patients preferred degludec treatment with FlexTouch (59 vs. 22%), preferred to continue (67 vs. 15%) and recommend (67 vs. 14%) use of FlexTouch compared with SoloStar with glargine U100. Conclusions: In this randomized, crossover trial, lower treatment impact and higher patient preference were reported for FlexTouch versus SoloStar pen injectors.

Randomized Controlled Trial Multicenter Study
Relationship of obesity to adverse events in myocardial infarction patients without primary percutaneous coronary intervention: results from the Occluded Artery Trial (OAT).
Objective: Our goal was to investigate the "obesity paradox" in myocardial infarction populations without primary percutaneous coronary intervention (PPCI). Methods: The Occluded Artery Trial (OAT, Clinicaltrials.gov: NCT00004562) is a randomized, multicenter study to investigate the influence of routine percutaneous coronary intervention (PCI) on the clinical outcomes of myocardial infarction patients without PPCI. We stratified these patients into three groups according to body mass index (BMI): normal, 18.5 kg/m2 ≤ BMI < 25 kg/m2; overweight, 25 kg/m2 ≤ BMI < 30 kg/m2; obese, BMI ≥ 30 kg/m2. ⋯ We did not find any statistical differences among BMI categories in terms of cardiac death or NYHA class IV heart failure. Conclusions: A U-shaped relationship was observed between BMI and all-cause mortality or non-cardiac death. Overweight patients have the lowest risk of all-cause mortality, which may be attributed to their having the lowest risk of non-cardiac death of the groups studied.

Background: Systematic reviews (SRs) and/or meta-analyses of in vitro research have an important role in establishing the foundation for clinical studies. In this study, we aimed to evaluate the reporting quality of SRs of in vitro studies using the PRISMA checklist. Method: Four databases were searched including PubMed, Virtual Health Library (VHL), Web of Science (ISI) and Scopus. ⋯ There was a positive but not significant correlation between the overall quality score and the journal impact factor of the included studies. Conclusions: The adherence of SRs of in vitro studies to the PRISMA guidelines was poor. Therefore, we believe that using reporting guidelines and journals paying attention to this fact will improve the quality of SRs of in vitro studies.
