Introduction: While chemoradiotherapy (CRT) is commonly employed as a curative approach for esophageal cancer, administering standard CRT to elderly patients often presents challenges in practical settings. The objective of this study was to compare treatment tolerance and survival outcomes between younger and elderly patients (aged ≥65 years) diagnosed with locally advanced esophageal cancer receiving curative-intent treatment. Additionally, it aimed to assess the impact of the Geriatric-8 Health Status Screening Tool (G8 score) on treatment decisions in elderly patients.

Objectives: Coronary microvascular dysfunction is present in large percentage of the population, and it has been shown to have a pathological and prognostic role in many conditions. Therefore, early detection of microvascular dysfunction is important, especially in selected populations. The aim of this study was to investigate the association of galanin with coronary flow reserve (CFR) in prehypertensive individuals to determine whether it can be used as a marker to detect microvascular dysfunction.

  • This study explores how inflammation affects outcomes in patients with ST-Elevation Myocardial Infarction (STEMI), specifically looking at in-hospital mortality and the modified Naples prognostic score (mNPS).
  • The research included 2,576 STEMI patients and analyzed various inflammatory markers, finding that higher levels of these markers, particularly mNPS, were linked to increased in-hospital mortality.
  • Results indicate that mNPS not only predicts in-hospital mortality more effectively than other inflammatory indices but also provides a net clinical benefit in assessing patient risk during hospitalization.

Objective: Transthoracic echocardiography is the gold standard method for screening and confirmation of acute rheumatic fever and subclinical rheumatic heart disease. Secondary antibiotic prophylaxis that is regularly employed in subclinical rheumatic heart disease may help to reverse mild rheumatic carditis lesions, delay the progression of the disease, reduce morbidity and mortality, and improve patients' quality of life.

Materials And Methods: We retrospectively evaluated the outcomes of 180 patients with subclinical rheumatic heart disease who were followed up for a mean of 4.

Endocrine therapy (ET) plus cyclin-dependent kinase (CDK) 4/6 inhibitors is a standard treatment for hormone receptor (HR) positive HER-2-negative metastatic breast cancer patients. In this study, we aimed to investigate the effect of body mass index (BMI) on progression-free survival (PFS) in patients receiving ET plus CDK 4/6 inhibitors. Patients with metastatic HR-positive breast cancer receiving CDK 4/6 inhibitors were included in the study.

Background And Objective: Lower urinary tract symptoms (LUTS) and overactive bladder (OAB) intimately affect the psychological wellbeing and mental health of men. However, to date, the association of aggression with LUTS and OAB has not been investigated. To address this knowledge gap, we evaluated the association of aggression with LUTS and OAB in a large representative cohort of men at the population level.

Nasal septal perforation (NSP) is a structural anomaly that affects the mucosa, cartilage, and bone of the nasal septum, often stemming from septoplasty as the primary cause. Spontaneous healing of a perforated septum is rare, and typically the healing process is observed until it is determined that the condition is stable and no longer deteriorating, at which point surgical intervention is considered. Numerous surgical techniques have been proposed for NSP repair.

Objectives: The aim of the study was to investigate whether retinal neurovascular structural impairment in children with partial biotinidase deficiency (BD) could be detected early via optical coherence tomography (OCT) and OCT angiography (OCTA).

Methods: Eighty patients with partial BD and 80 control cases without any known systemic or ocular diseases were enrolled in this prospective study. Retinal neurovascular structures in the macular and optic disc regions were examined in using OCT and OCTA.

Purpose: The internet has become a primary source for patients seeking healthcare information, but the quality of online information, particularly in orthopaedics, often falls short. Orthopaedic surgeons now have the added responsibility of evaluating and guiding patients to credible online resources. This study aimed to assess ChatGPT's ability to identify deficiencies in patient information texts related to total hip arthroplasty websites and to evaluate its potential for enhancing the quality of these texts.

  • Morphea is a rare autoimmune disease affecting the skin and subcutaneous tissues, with this study analyzing 78 patients to explore its demographic, clinical, and histological characteristics between 2016 and 2022.
  • The plaque type was the most common clinical presentation (87.5%), with significant histopathological findings such as complete homogenization of dermal collagen (100%) and significant loss of skin appendages (98.7%).
  • Key observations included varying histopathological features and a notable association of certain signs in lower extremity lesions, suggesting morphea’s complex diagnosis may require careful clinical correlation.

In vitro modulation of T cells in myasthenia gravis by low-dose IL-2.

Eur J Immunol

November 2024

Department of Physiology, Istanbul Medical Faculty, Istanbul University, Istanbul, Turkey.

Follicular helper (Tfh), peripheral helper (Tph), and regulatory (Treg) T cells are involved in myasthenia gravis (MG) pathogenesis, an autoimmune disorder arising from autoantibodies targeting neuromuscular junction proteins. This study explores the impact of low-dose IL-2 on Tfh, Tph, and Treg cells in vitro in MG. Acetylcholine-receptor antibody-positive MG (AChR-MG), muscle-specific kinase antibody-positive MG (MuSK-MG) patients, and healthy controls (HC) were studied.

  • Pilomatrixoma is a rare, non-cancerous tumor linked to hair follicles, typically diagnosed through excisional biopsy, though fine-needle aspiration (FNA) is also used with limited reports on its cytological characteristics.
  • This study analyzed six cases of pilomatrixoma, confirming diagnoses through cytological features such as various cell types and quantifying them on a scale to understand the tumor's characteristics.
  • The findings highlight that although FNA can pose diagnostic challenges, indicators like ghost cells and basaloid cells can suggest pilomatrixoma, supported by other cellular features in cytology reports.

  • The study aimed to determine if patients who underwent percutaneous liver mass biopsy (PLMB) could be safely discharged after a two-hour monitoring period.
  • It involved 375 patients and found that minor complications occurred in 18.93% and major complications in 2.13%, mostly within the first two hours.
  • The conclusion indicated that the two-hour monitoring is sufficient for identifying most complications, suggesting that longer monitoring does not significantly enhance patient care.

Clinic of Anesthesiology and Reanimation, University of Health Sciences, Bağcılar Training and Research Hospital, Istanbul, Turkiye; Department of Molecular Biology and Genetics, Institute of Graduate Studies in Sciences, Istanbul University, Istanbul, Turkiye. Electronic address:

General anesthetics exposure, particularly prolonged or repeated exposure, is a crucial cause of neurological injuries. Notably, isoflurane (ISO), used in pediatric anesthesia practice, is toxic to the developing brain. The relatively weak antioxidant system at early ages needs antioxidant support to protect the brain against anesthesia.
