Background: This study evaluated the long surgical gauze (SurG) technique as a liver retraction method in laparoscopic sleeve gastrectomy (LSG). Traditional methods involve the Nathanson retractor, associated with ischemia and necrosis complications. In addition, these techniques require an additional trocar with an incision that increases postoperative pain.

Importance: Retrieval strategies for children, adolescents, and young adults with relapsed classic Hodgkin lymphoma (cHL) aim to maintain efficacy while minimizing long-term toxic effects. Children, adolescents, and young adults with low-risk, relapsed cHL may benefit from replacing high-dose chemotherapy and autologous stem cell transplant with less intensive involved-site radiotherapy (ISRT).

Objective: To evaluate a risk-stratified, response-adapted, transplant-free approach for treatment of children, adolescents, and young adults with low-risk relapsed cHL with nivolumab plus brentuximab vedotin (BV) followed by BV plus bendamustine for patients with suboptimal response and ISRT (30.

Article Synopsis
  • The study aimed to assess how three-dimensional (3D) modeling of MRI images affects positive surgical margins (PSM) in patients undergoing radical retropubic prostatectomy (RRP).
  • A total of 81 patients were split into two groups: one group used 3D modeling to guide surgery, while the other relied on traditional evaluations of MRI scans.
  • Results showed that the 3D group had a significantly lower PSM rate (14.6%) compared to the non-3D group (45%), highlighting the benefits of 3D modeling and collaboration between radiologists and surgeons for better surgical outcomes.

G protein-coupled receptor (GPCR) signaling is terminated by arrestin binding to a phosphorylated receptor. Binding propensity has been shown to be modulated by stabilizing the pre-activated state of arrestin through point mutations or C-tail truncation. Here, we hypothesize that pre-activated rotated states can be stabilized by small molecules, and this can promote binding to phosphorylation-deficient receptors, which underly a variety of human disorders.

Objective: This study aimed to develop and validate the Developmental Origins of Health and Disease (DOHaD) awareness scale and examine whether having a DOHaD education module may affect dietary behavior in college students.

Background: Some studies conducted within the scope of the DOHaD hypothesis show associations between early-life environmental factors, especially maternal health and nutritional status, with the next generation's health and disease status. Despite the increase in elucidating of the underpinning mechanisms of early life determinants and chronic disease risk, there is limited knowledge on how public perceive and understand DOHaD concepts.

Objective: Type 1 diabetes mellitus (T1D) is a chronic disease that is common in childhood and adolescence, where care and metabolic control are difficult for both adolescents and their parents. Parental participation in the care and treatment process, especially during adolescence when adolescents develop autonomy and take responsibility for self-care, affects both the adolescent's perception of autonomy and may cause difficulties in self-management. This study was conducted to determine the effect of parental support on adolescents' self-efficacy, quality of life (QoL) and glycaemic control in adolescents with T1D.

The ketogenic diet (KD) originated in the 1920s. It is a dietary model that is low in carbohydrates, adequate in protein, and high in fat content. The diet mimics starvation and increases the production of ketone bodies, leading to ketosis in metabolism.

Background: The spread of antibiotic-resistance genes among healthcare-associated infections (HAIs) poses serious problems in the treatment of these infections. Recently, these resistance genes have also been shown to be present in integrons.

Objectives: By focusing on integron-mediated mechanisms of antibiotic resistance, we sought to elucidate the genetic determinants underpinning the development of multidrug resistance in clinical isolates of Acinetobacter baumannii.

Our study retrospectively examines the number of granulocytes in the products of donors who donated granulocytes between January 2016 and September 2020 at the Hacettepe University Faculty of Medicine Blood Bank. The effects of acid-citrate-dextrose (ACD), trisodium citrate + hydroxyethyl starch (TCC + HES) and ACD + HES combinations used in the apheresis procedure on the granulocyte count of apheresis products were examined. As a result of study, it was seen that the type of anticoagulant combination used during apheresis significantly affected the number of granulocytes collected.

Background: This study aimed to investigate the causes of failure after the ileal pouch-anal anastomosis (IPAA) procedure for ulcerative colitis (UC) and to determine the independent risk factors affecting their quality of life.

Methods: This multi-center cohort study included all UC patients who underwent IPAA at nine referral centers in Türkiye from 2010 to 2018. Centers were categorized as high-volume (≥10 cases/year) or low-volume (<10 cases/year).

Background: Liver retraction management in laparoscopic sleeve gastrectomy (LSG) is challenging for surgeons, especially in patients with enlarged livers. Traditional methods, such as the Nathanson retractor (NR), often necessitate additional incisions, potentially increasing liver enzymes and increasing the risk of complications. The aim of this study was to evaluate the efficacy of the use of a Veress needle (VN), an alternative liver retraction technique, in LSG surgery compared with NR.

Purpose: Sacrococcygeal pilonidal disease (SPD) is a global concern, notably in Southeast Europe and the Middle East. Unroofing curettage (UC), which provides faster recovery, better cosmetic appearance, and lower recurrence rates in the primary cases, was evaluated with the results of recurrent disease.

Methods: This retrospective study included 74 patients with recurrent disease who were over 16 years of age, experienced recurrence after at least one surgical attempt, and underwent unroofing curettage between 2007 and 2019.

Objective: Tumor necrosis factor alpha inhibitors are frequently used in the treatment of axial spondyloarthritis. While tumor necrosis factor alpha is associated with some malignancies, studies on its effects on thyroid functions and thyroid nodules are limited. This study aimed to assess the effect of tumor necrosis factor alpha inhibitors treatments on the evaluation of thyroid nodules and thyroid function tests in axial spondyloarthritis patients.

Neuroinflammation can be triggered by a high-fat/high-fructose diet (HFFD), and CD36 may be an underlying mechanism. Lauric acid (LA), the major fatty acid in coconut oil, and resveratrol, the plant-based polyphenolic compound, may exert anti-inflammatory effects. Therefore, this study investigated the possible effects of LA and resveratrol on diet-induced neuroinflammation and CD36.

Acne vulgaris (AV) is a chronic inflammatory skin condition predominantly observed during adolescence. Interoception accuracy (IAc) refers to the ability to perceive internal bodily states such as hunger and thirst. Since the brain and skin originate from the same embryological layer, the ectoderm, it is hypothesized that skin changes and disorders might affect individual perceptions.
