Department of Pediatric Rheumatology, İstanbul University-Cerrahpaşa, Cerrahpaşa Faculty of Medicine, İstanbul, Türkiye.

Autoinflammatory bone diseases (AIBDs) constitute a recently identified subset of autoinflammatory diseases. These conditions are characterized by an exaggerated inflammatory response in the bones without any apparent etiology. Inflammatory bone lesions associated with AIBDs exhibit chronic inflammation, are typically culture-negative, and do not exhibit discernible microorganisms on histopathological examination.

Background: Morphological growth naturally progresses with age; however, the rate of growth varies across different parts of an organism, with certain structures developing more rapidly than others. This study aimed to analyze and compare the skull development of red foxes (Vulpes vulpes) during two specific developmental stages: the 3rd and 6th months, which represent distinct growth phases in their early ontogeny.

Methods: In this study, we aimed to analyze and compare skull development in red foxes (Vulpes vulpes) during two specific post-natal time points: the 3rd and 6th months.

This study was aimed to identify the most frequently observed pathogens in uncomplicated urinary tract infections from outpatient urinary isolates obtained across seven different geographical regions in Türkiye and to determine whether the antibiotic resistance rates of these pathogens differ significantly between these regions. The study included patients aged 18 to 65 years who were diagnosed with uncomplicated urinary tract infections and had positive urine cultures from March 2021 to August 2022, across 37 different centers in Türkiye. The participating centers were selected based on their use of the disk diffusion method, in line with the European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines, to ensure standardization of urine culture data.

Article Synopsis
  • The study aimed to enhance early diagnosis of candidemia in ICU patients by identifying risk factors and developing a new scoring system, known as the Cerrahpaşa score.
  • A retrospective analysis of 100 ICU patients revealed key risk factors such as sepsis and prolonged antibiotic use, while a prospective evaluation of 75 patients established a cutoff score of ≥4 points as indicative of increased candidemia risk.
  • The research concluded that the Cerrahpaşa score, combined with a real-time PCR assay, could improve the early detection and management of candidemia in critically ill patients.

Life expectancy provides insights into population health and the socio-economic development level of a country. However, there has been a significant gap in life expectancy between developed and underdeveloped countries, although these countries and international institutions have focused on reducing these inequalities. This article explores the long-term effects of social, educational, and health expenditures together with GDP on indicators of life expectancy in the OECD states over the period of 2005-2021 through second-generation cointegration analysis.

Cerebral cortex development in humans is a highly complex and orchestrated process that is under tight genetic regulation. Rare mutations that alter gene expression or function can disrupt the structure of the cerebral cortex, resulting in a range of neurological conditions. Lissencephaly ('smooth brain') spectrum disorders comprise a group of rare, genetically heterogeneous congenital brain malformations commonly associated with epilepsy and intellectual disability.

This study was performed to evaluate the regenerative capabilities of levan hydrogels when combined with conventional bone graft materials (Bio-Oss®) in guided bone regeneration (GBR). With the growing interest in the application of levan polysaccharide for regenerative purposes over the last decade, a noticeable gap in in-vivo validations remains. This research therefore fills this gap by utilizing the cytocompatibility and cell proliferation potential of levan hydrogels and marks a preliminary effort in its use in combination with Bio-Oss® for bone regeneration, which was examined both in-vitro and in-vivo for the first time.

Introduction: The sense of smell is one of the most developed and important senses that forms the bond between the newborn and the mother and allows the newborn to reach the mother's breast. The sense of smell begins to form during intrauterine life, and the sense of smell can be a marking tool for a newborn baby, so that the baby can recognize both his mother and his immediate environment and develop his behaviour accordingly. This is necessary not only for feeding babies but also for them to feel safe and peaceful in their new environment.

This study evaluated the management of dyslipidemia in Turkey with the goal of understanding current diagnosis and treatment patterns, as well as identifying unmet needs in achieving effective low-density lipoprotein cholesterol (LDL-C) targets. Using a Delphi panel consisting of nine expert cardiologists, the study reveals key gaps in dyslipidemia management, particularly in the underutilization of combination therapies, such as statins and PCSK9 inhibitors, which are crucial for achieving LDL-C targets in high-risk patients. The findings indicate that while many patients with very high cardiovascular risk are diagnosed, a significant proportion do not receive optimal treatment to reach LDL-C levels recommended by European guidelines.

: Childhood obesity is a global health problem that affects at least 41 million children under the age of five. Increased BMI in children is associated with serious long-term health consequences, such as type 2 diabetes, cardiovascular disease, and psychological problems, including depression and low self-esteem. Although the etiology of obesity is complex, research suggests that the diet and lifestyle of pregnant women play a key role in shaping metabolic and epigenetic changes that can increase the risk of obesity in their children.

The Anti-Inflammatory Roles of Vitamin D for Improving Human Health.

Curr Issues Mol Biol

November 2024

Department of Family Medicine, Cerrahpasa Medical Faculty, Istanbul University-Cerrahpasa, Istanbul 34098, Turkey.

Vitamin D receptors (VDRs) are present in almost all cells of the immune system, including B cells, T cells, NK (Natural Killer) cells, dendritic cells, and monocytes, as well as the epithelial cells of many organs such as the intestine, pancreas, prostate, lungs, and cardiomyocytes. In addition, some immune cells, including dendritic cells, macrophages, and B and T cells, can synthesize calcitriol by expressing 1α-hydroxylase. Upon binding to VDRs, vitamin D (Vit D) regulates the expression of genes involved in immune responses, including those encoding for cytokines.
