Globorisk is a country-specific risk prediction model that estimates 10-year cardiovascular disease (CVD) risk. This study aims to evaluate the agreement between different versions of Globorisk and their ability to predict CVD in a nationwide Turkish cohort. Baseline data from 5449 participants aged 40-74 were obtained from Türkiye Chronic Diseases and Risk Factors Survey 2011.

Cervical cancer, closely linked to human papillomavirus (HPV) infection, is a major global health concern. Our study aims to fill the gap in understanding HPV vaccine awareness and acceptance in the Middle East, where national immunization programs are often lacking and cultural perceptions hinder acceptance. This systematic review and meta-analysis adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Background: The incidence of Hepatitis A is increasing worldwide. Yearly classification of Hepatitis A Seroprevalence for different times in different regions of Türkiye allows indirect measurement of year-specific incidence rates of HAV infection and can be considered the best way to define Hepatitis A status. This study aimed to examine the change in the incidence of hepatitis A by systematically evaluating the available data on the seroprevalence of anti-HAV antibodies in the Turkish population.

Article Synopsis
  • This study analyzed 331 patients with primary brain abscesses (PBAs) from 39 centers in 16 countries, focusing on infection causes, risk factors, and mortality outcomes over a 12-year period.
  • Study results showed that the majority of patients were middle-aged men (average age 46.8), with symptoms like headaches and fever; Gram-positive cocci were the most common pathogens.
  • Key factors influencing mortality at 42 days included intravenous drug use and malignancy, while factors affecting 180-day mortality included temporal lobe involvement and the presence of unidentified bacteria.

Tumor deposits (TDs) are defined as discontinuous neoplastic masses within the lymphatic drainage pathway of the primary tumor. The poor prognostic implication of these masses have been demonstrated in various cancers. The aim of this study is to investigate the incidence of TDs in our thyroid carcinoma cases, which has not been studied so far to the best of our knowledge, and to determine the prognostic value of their existence.

Objective: Contact tracing aids epidemic control by enabling early detection and isolation without overburdening healthcare systems despite potential challenges. This study aimed to evaluate the practical application of contact and risk assessment-based models in predicting SARS-CoV-2 infection following exposure among healthcare workers in a large tertiary public university hospital in Türkiye.

Materials And Methods: The study was designed as a retrospective cohort study, including contact tracing data from 3389 exposed healthcare workers from March 23, 2020, to October 22, 2021.

Article Synopsis
  • Sepsis is a serious condition caused by an abnormal immune response to infection, and the study focuses on how genetic differences in the vitamin D receptor (VDR) gene, specifically the FokI polymorphism, may influence outcomes in sepsis patients.
  • The study analyzed 192 patients (96 with sepsis and 96 without) in the ICU and found that in-hospital mortality was significantly higher in the sepsis group (27.1%) compared to the non-sepsis group (8.33%).
  • Results indicated that while there was no significant difference in VDR genotype frequencies between survivors and non-survivors in the sepsis group, those with the homozygous C allele had lower mortality rates, suggesting a potential

The aim of the present study was to investigate whether patients with psoriasis are prone to urolithiasis. Prospective analysis of 67 patients diagnosed as psoriasis (PS group) and 65 volunteers who had never been diagnosed as psoriasis (NPS group) was performed. The levels of oxalate, citrate, calcium, uric acid, magnesium, creatinine, and sodium were evaluated by analyzing the 24-h urine samples.

Objective: Pleural fluid pH measurement is recommended for tube thoracostomy decisions in complicated parapneumonic pleural effusions. However, pleural fluid pH may be affected by blood pH in critically ill patients with common systemic acid-base disorders. We aimed to investigate the use of pleural fluid lactate to distinguish culture-positive parapneumonic effusions from other pleural effusions.

Objective: Coronavirus disease 2019 (COVID-19) can cause acute respiratory distress syndrome (ARDS). Invasive mechanical ventilation (IMV) support and prone positioning are essential treatments for severe COVID-19 ARDS. We aimed to determine the combined effect of prone position and airway pressure release ventilation (APRV) modes on oxygen improvement in mechanically-ventilated patients with COVID-19.

Objective Coronary collateral circulation (CCC) are vascular structures that limit the infarct area, protect left ventricular function, and reduce the frequency of arrhythmia and mortality during myocardial ischemia and infarction. In this study, we examined the relationship between the development of CCC and serum adropin levels, which has been shown in previous studies to regulate endothelial functions and increase endothelial nitric oxide synthesis, in patients with acute myocardial infarction. Methods This study included 41 patients with insufficient CCC and 43 patients with well-developed CCC who were hospitalized for acute myocardial infarction and underwent coronary angiography.

This report aimed to determine the effects of different preservatives used to maintain the integrity of urine samples for a 24-hour urine collection on urinary iodine measurement by the Sandell-Kolthoff method . The selected preservatives were hydrochloric acid, acetic acid, boric acid, sodium carbonate, sodium fluoride, thymol with isopropanol, sodium chloride with formalin, and Saccomanno fixative. The test samples to which these preservatives were added and the control samples for basal measurements were prepared from the urine pool obtained from urine samples taken from healthy volunteers.

Background: Characterizing the post-COVID health conditions is helpful to direct patients to appropriate healthcare.

Aims: To describe the presence of symptoms in COVID-19 patients within 6 months after diagnosis and to investigate the associated factors in terms of reporting symptoms.

Methods: Data of DEU-COVIMER (a telephone interview-based COVID-19 follow-up center established in a tertiary care hospital) was analyzed for SARS-CoV-2 RNA positive participants aged ≥ 18 years from November 1st, 2020, to May 31st, 2021.

Objective: West Nile Virus (WNV), which causes widespread outbreaks in different parts of the world, is a risk to public health in Turkey, too. Community-based study data are needed to identify measures against possible outbreaks. This study aimed to determine the seroprevalence of community-based WNV in Manisa and to investigate the relationship between sociodemographic and socioeconomic variables.

Childhood obesity/overweight is a worldwide concern and its prevalence is increasing in many countries. The first aim of this study is to analyse the trends in overweight and obesity among children under the age of five in Turkey based on the new World Health Organization (WHO) standards, using data from the 'five-round of the Turkey Demographic and Health Surveys' (TDHSs). The second aim is to examine whether or not the maternal/household and individual-level factors are associated with overweight/obesity using TDHS 2003, 2008, and 2013 datasets.

Background: Healthcare workers (HCWs) have an increased risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection due to occupational exposure. Strict measures generally focus on the patient-to-HCW contacts. However, interactions between the HCWs also pose a high risk for SARS-CoV-2 exposure.

Epistasis-gene-gene interaction-is common for mutations with large phenotypic effects in humans and model organisms. Epistasis impacts quantitative genetic models of speciation, response to natural and artificial selection, genetic mapping, and personalized medicine. However, the existence and magnitude of epistasis between alleles with small quantitative phenotypic effects are controversial and difficult to assess.

Background: Healthcare workers (HCWs) have increased risk for SARS-CoV-2 infection via contacts in hospitals, as well as via transmission in the community. Serial interval, which is defined as the time between symptom onsets in an infector-infectee pair, and the incubation period are key parameters in determining the control strategies for COVID-19. This study aimed to evaluate surveillance of HCWs and estimate the serial interval and incubation period of COVID-19.
