Aims: Bidirectional detrimental relationships between COVID-19 infection and diabetes have been described globally. However, new-onset diabetes in adults and its follow-up during the pandemic have not been sufficiently investigated. In this study, new-onset autoimmune and type 2 diabetes cases during the pandemic were compared to those before the pandemic, and the clinical course of new-onset diabetes during the pandemic was examined.

Purpose:   Familial hypercholesterolemia (FH) is a genetic disorder associated with extremely high levels of low-density lipoprotein cholesterol (LDL-C) and increased incidence of cardiovascular disease. We aimed to evaluate the efficacy and long-term outcomes of lipoprotein apheresis (LA) in the treatment of FH.

Methods:   Cardiovascular events that occurred before and after LA treatment were evaluated by reviewing previous medical records of patients with FH.

Background And Objective: Although many studies on the Diabetes Eating Problem Survey-Revised (DEPS-R) in adolescents with type 1 diabetes mellitus (T1D), the number of studies validating this questionnaire in adults with T1D is limited. Therefore, this study aimed to examine the factor structure of the Turkish version of the DEPS-R in adults with T1D and internal consistency and construct validity.

Methods: A total of 100 patients with T1D, ages 18-50 years, completed the DEPS-R and EDE-Q.

Background: The risk of cardiovascular disease is correlated with the frequency and control of associated risk factors in diabetes mellitus and may vary according to country. We evaluated risk factors for cardiovascular disease, cardiovascular events, and the use of preventive medications in patients with diabetes mellitus using the Prospective Urban and Rural Epidemiological Türkiye cohort.

Methods: Patients with diabetes mellitus versus without diabetes mellitus were compared for risk factors, cardioprotective drugs (angiotensin-converting enzyme inhibitors or angiotensin-II receptor antagonists, statins, and antiplatelets), and cardiovascular events.

Aims: To develop a healthy diet score that is associated with health outcomes and is globally applicable using data from the Prospective Urban Rural Epidemiology (PURE) study and replicate it in five independent studies on a total of 245 000 people from 80 countries.

Methods And Results: A healthy diet score was developed in 147 642 people from the general population, from 21 countries in the PURE study, and the consistency of the associations of the score with events was examined in five large independent studies from 70 countries. The healthy diet score was developed based on six foods each of which has been associated with a significantly lower risk of mortality [i.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic led to a lockdown period. Confinement periods have been related to unhealthy lifestyle behaviors. Our study aimed to determine weight change, changes in eating and exercise habits, the presence of depression and anxiety, and diabetes mellitus (DM) status in a cohort of patients with obesity.

Background: Final adult height is a useful proxy measure of childhood nutrition and disease burden. Tall stature has been previously associated with decreased risk of all-cause mortality, decreased risk of major cardiovascular events and an increased risk of cancer. However, these associations have primarily been derived from people of European and East Asian backgrounds, and there are sparse data from other regions of the world.

Objective: We aimed to compare cardiovascular (CV) events, all-cause mortality, and CV mortality rates among adults with and without diabetes in countries with differing levels of income.

Research Design And Methods: The Prospective Urban Rural Epidemiology (PURE) study enrolled 143,567 adults aged 35-70 years from 4 high-income countries (HIC), 12 middle-income countries (MIC), and 5 low-income countries (LIC). The mean follow-up was 9.

Objective: Metabolic syndrome (MetS) includes several cardiovascular (CV) risk factors. This study aimed to assess CV risk of MetS, contribution of its components to the risk, and whether MetS provides additional risk beyond its components.

Methods: The Prospective Urban Rural Epidemiology (PURE) Turkey cohort included 3933 individuals aged between 35 and 70 years, with a median follow-up of 8.

Objectives: This study was designed to determine the prevalence of metabolic syndrome (MS) in Turkish children and to examine the relationship between MS components in this age group.

Methods: A total of 395 students in Istanbul aged 10 to 14 years in the 2004-2005 school year were enrolled in the study. Body weight, height, waist circumference, hip circumference, and systolic-diastolic blood pressure were measured.

Background: The associations between the extent of forced expiratory volume in 1 s (FEV) impairment and mortality, incident cardiovascular disease, and respiratory hospitalisations are unclear, and how these associations might vary across populations is unknown.

Methods: In this international, community-based cohort study, we prospectively enrolled adults aged 35-70 years who had no intention of moving residences for 4 years from rural and urban communities across 17 countries. A portable spirometer was used to assess FEV.

Background: Several international guidelines recommend the consumption of two servings of fruits and three servings of vegetables per day, but their intake is thought to be low worldwide. We aimed to determine the extent to which such low intake is related to availability and affordability.

Methods: We assessed fruit and vegetable consumption using data from country-specific, validated semi-quantitative food frequency questionnaires in the Prospective Urban Rural Epidemiology (PURE) study, which enrolled participants from communities in 18 countries between Jan 1, 2003, and Dec 31, 2013.

Fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) have been used to diagnose new-onset diabetes mellitus (DM) in order to simplify the diagnostic tests compared with the 2-hour oral glucose tolerance test (OGTT; 2-hPG). We aimed to identify optimal cut-off points of high sensitive C-reactive protein (hs-CRP) in new-onset DM people based on FPG, 2-hPG, or HbA1c methods. Data derived from recent population-based survey in Turkey (TURDEP-II).

Background: We aimed to investigate the effects of a regular exercise program on exercise capacity, blood biochemical profiles, certain antioxidant and oxidative stress parameters of type 2 Diabetes mellitus (DM) patients.

Methods: Thirty one type 2 DM patients (ages ranging from 42-65 years) who have hemoglobin A1c (HbA1c) levels ≥7.5% and ≤9.

Aim: The present study investigated the effects of growth hormone (GH), insulin-like growth factor-1 (IGF-1), insulin-like growth factor binding protein-3 (IGFBP-3) and GH-receptor (GHR)/exon-3 polymorphism on diabetes mellitus (DM) and coronary heart disease (CHD) patients.

Patients And Methods: Ninety patients with CHD, 90 patients with DM and 96 controls were included in this study. The GH, IGF-1 and IGFBP-3 serum levels were measured with enzyme-linked immunosorbent assay.

Objective: Sex hormone binding globulin (SHBG) levels are often low in women with polycystic ovary syndrome (PCOS). In addition to metabolic and nutritional factors, SHBG levels are determined by genetic polymorphisms in SHBG gene. The aim of this study was to investigate the association of polymorphisms in exon 8 of SHBG gene with anthropometric and biochemical features of women with PCOS.
