Background: The incidence of non-alcoholic fatty liver disease (NAFLD) is increasing with obesity, and it is believed that the ongoing low-grade inflammation in obesity and alterations in the enterohepatic axis contributing this process. This study aimed to determine the role of fecal calprotectin (FC) as inflammatory biomarker in obesity and NAFLD.

Methods: Between November 2022-August 2023, 31 obese and 10 healthy adolescents aged between 10 and 18 years enrolled in this prospective controlled study.

Objective: The question of whether severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection influences ovarian function and oocyte quality has arisen as angiotensin converting enzyme-2 receptors, which facilitates viral infection, are found on reproductive system tissues, including the vagina, placenta, uterus, and ovaries. The primary objective of this prospective study was to evaluate the impact of SARS-CoV-2, on ovarian function, with a focus on anti-Mullerian hormone (AMH) and acute phase reactant levels in patients well after recovery from coronavirus disease-2019 (COVID-19).

Material And Methods: This prospective cohort study was conducted in the department of obstetrics and gynecology at a single center between October 2020 and June 2021.

Polycystic ovary syndrome (PCOS) is a heterogeneous familial disorder affecting up to one in five women. The aetiology remains unclear, but available evidence suggests it is a polygenic disorder with epigenetic, developmental, and environmental components. The diagnostic criteria for PCOS are based on reproductive features, and the syndrome is categorized into several phenotypes that can vary by race and ethnicity.

Article Synopsis
  • * Out of 90 RTR participants, the median antibody level was 16.7 AU/mL at 42 days post-first dose, with 60% showing positive serology; mycophenolic acid (MFA) and ACE inhibitors were found to decrease seropositivity.
  • * Patients who received the Pfizer/BioNTech booster had better antibody levels and lower COVID-19 infections compared to those with the CoronaVac/Sinovac booster, indicating that heterologous vaccination is more effective for RTRs.

Article Synopsis
  • This study investigates the link between sepsis-induced acute kidney injury (AKI) and worse outcomes in patients in the intensive care unit (ICU), focusing on identifying risk factors for new-onset AKI among septic patients who initially had no kidney issues.
  • Conducted at Gazi University Hospital, the research involved analyzing data from septic patients aged 18 and older, looking at demographics and clinical factors to determine predictors of AKI development and mortality rates.
  • Results showed a significant incidence of new-onset AKI (36%), particularly linked to factors like invasive mechanical ventilation, new-onset shock, and higher APACHE-II scores, all of which correlated with longer ICU stays and increased mortality risk.*

Euglycemic diabetic ketoacidosis (DKA) is a rare complication of diabetes mellitus (DM) characterized by metabolic acidosis, ketosis, and blood glucose levels < 250 mg/dL. The prevalence of euglycemic DKA is increasing with the popularity of ketogenic (low-carbohydrate) diets. We present herein the case of a patient with newly diagnosed type 1 DM who developed euglycemic DKA following a ketogenic diet.

Objective: This study aimed to investigate the relationship between procalcitonin (PCT) kinetic and estimated glomerular filtration rates (eGFR) in critically ill patients who had Gram-negative primary bloodstream infection (GN-BSI) and responded to the antimicrobial therapy.

Materials And Methods: This single-centered study was retrospective and observational. Critically ill GN-BSI patients over 18 years old who had clinical and microbiological responses to antibiotic treatment were included in the study.

Fetal growth is known to be affected by ethnic and environmental factors; therefore, intrauterine growth references for each community vary and need to be determined individually. This study aimed to construct intrauterine growth references for Turkish infants. This prospective, multicenter, cross-sectional study was performed in collaboration with the Turkish Ministry of Health and the Turkish Neonatology Society, in coordination with Mersin University.

Aim: The utility of the venous excess ultrasound (VExUS) score in predicting mortality remains uncertain in acute kidney injury (AKI) patients.

Material And Methods: This was a post-hoc study involving 246 AKI patients presenting to a tertiary care emergency department. Venous ultrasound assessments were conducted to determine the VExUS score.

The coronavirus disease 2019 (COVID-19) has raised concerns about the potential complications it may cause in pregnant women. Therefore, biomarkers that can predict the course of COVID-19 in pregnant women may be of great benefit as they would provide valuable insights into the prognosis and, thus, the management of the disease. In this context, the objective of this study is to identify the biomarkers that can predict COVID-19 progression in pregnant women, focusing on composite hemogram parameters and systemic inflammatory and spike markers.

Article Synopsis
  • The study aimed to assess the vaccine response and impact of the BNT162b2 booster on COVID-19 positivity in haemodialysis (HD) and peritoneal dialysis (PD) patients previously vaccinated with two doses of CoronaVac.
  • A total of 80 PD and 163 HD patients were analyzed for antibody levels at various intervals post-vaccination, noting that all patients receiving the BNT162b2 booster showed seropositivity, while those who received another CoronaVac booster did not.
  • Results suggested that older age increased COVID-19 positivity, but receiving the booster significantly reduced this risk, highlighting the potential need for additional vaccination doses for patients undergoing dialysis.

Article Synopsis
  • The study focused on using venous system ultrasound (VExUS) in the emergency department (ED) to determine the causes of acute kidney injury (AKI), which can be complex to diagnose.
  • Conducted over a year, the study evaluated 150 AKI patients, finding that hypovolaemia was the most common cause, followed by cardiorenal, systemic vasodilatation, and renal types.
  • VExUS demonstrated good diagnostic accuracy for cardiorenal AKI and fair accuracy for hypovolaemic AKI, but was less effective in identifying the other subtypes.

Background/aim: Multiple sclerosis (MS) is an inflammatory demyelinating central nervous system (CNS) disease. Among the paraclinical tests, brain and spinal Magnetic Resonance Imaging (MRI) is primarily involved in the diagnosis process, and cerebrospinal fluid (CSF) analysis is fundamental in diagnosing MS and the differential diagnosis. A positive relationship was demonstrated between oligoclonal band (OCB) positivity, CSF band number and immunoglobulin G(IgG) index.

Introduction: The advances in immune checkpoint inhibitors (ICIs) were relatively slow in rare tumors. Therefore, we conducted a multi-center study evaluating the efficacy of ICI monotherapy and the combination of ICIs with chemotherapy (CT) in patients with advanced rare tumors.

Methods: In this retrospective cohort study, we included 93 patients treated with ICIs for NCI-defined rare tumors from the 12 cancer centers in Turkey.

Introduction: Computerized thoracic tomography (CT) imaging was extensively employed, especially in the early months of the COVID-19 pandemic. An incidental thyroid nodule (ITN) is defined as a nodule not previously detected or suspected clinically but identified via an imaging study. The present study aimed to determine the incidence of thyroid nodules incidentally detected in thoracic CTs for the suspicion of COVID-19 pneumonia.

Background: TNF-related apoptosis-inducing ligand (TRAIL) is a member of the TNF superfamily that can either induce cell death or activate survival pathways after binding to death receptors (DRs) DR4 or DR5. TRAIL is investigated as a therapeutic agent in clinical trials due to its selective toxicity to transformed cells. Macrophages can be polarized into pro-inflammatory/tumor-fighting M1 macrophages or anti-inflammatory/tumor-supportive M2 macrophages and an imbalance between M1 and M2 macrophages can promote diseases.
