Background: The prevalence of meningococcal carriage and serogroup distribution is crucial for assessing the epidemiology of invasive meningococcal disease, forecasting outbreaks and formulating potential immunization strategies. Following the meningococcal carriage studies conducted in Turkey in 2016 and 2018, we planned to re-evaluate meningococcal carriage in children, adolescents and young adults during the COVID-19 pandemic period.

Methods: In the MENINGO-CARR-3 study, we collected nasopharyngeal samples from 1585 participants 0-24 years of age, across 9 different centers in Turkey.

Cervical subcutaneous emphysema and pneumomediastinum without pneumothorax are exceedingly rare complications following rhinoplasty, with limited cases reported in the literature. This report presents a case of revision septorhinoplasty using autologous costal cartilage, where the patient complained of a sore throat 36 hours postoperatively. On physical examination, cervical subcutaneous emphysema was palpated, and radiologic evaluation confirmed both cervical subcutaneous emphysema and pneumomediastinum.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma (NHL) in adults, constituting a significant portion of global incidence rates. DLBCL can be further classified via genetic expression profiling into molecular subsets consisting of not-otherwise specified (NOS) subset being the most prevalent, germinal center B-cell-like (GCB) subset, and activated B-cell-like (ABC) subset. The ABC subset, marked by abnormal NF-κB signaling, is associated with poorer outcomes.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Objective: The aim of this study was to evaluate the relationship between subclinical lymphedema identified prior to surgical intervention and clinical lymphedema observed in the late period, the incidence of lymphedema in our cohort, and the associated risk factors.

Materials And Methods: This prospective study was conducted with early-stage breast cancer patients who had been enrolled in a previous study. For diagnosing lymphedema, physical examination, L-Dex® score, and circumferential measurement was used.

Objective: To investigate integrating an artificial intelligence (AI) system into diagnostic breast ultrasound (US) for improved performance.

Materials And Methods: Seventy suspicious breast mass lesions (53 malignant and 17 benign) from seventy women who underwent diagnostic breast US complemented with shear wave elastography, US-guided core needle biopsy and verified histopathology were enrolled. Two radiologists, one with 15 years of experience and the other with one year of experience, evaluated the images for breast imaging-reporting and data system (BI-RADS) scoring.

Objective: This study aims to compare the results of cases with a history of assault presented to our emergency department over a period of three years with literature data and to share our experiences with colleagues.

Methods: Demographic characteristics, trauma findings, clinical conditions, surgical interventions, mortality, and outcomes of patients with a history of assault to the emergency department between 2020 and 2022 were retrospectively examined. The results were analyzed using the Number Cruncher Statistical System 2007 Statistical Software package program (Utah, USA).

Immune checkpoint inhibitors (ICIs) have significantly improved the five-year survival rate for advanced melanoma. However, many patients exhibit resistance to ICI therapy. This study evaluated the efficacy and prognostic factors of anti-PD-1 (Group A) and nivolumab-ipilimumab (Group B) therapy in patients with advanced melanoma who were resistant to prior ICI therapy.

Background: Covered stent correction for a sinus venosus atrial septal defect (SVASD) was first performed in 2009. This innovative approach was initially viewed as experimental and was reserved for highly selected patients with unusual anatomic variants. In 2016, increasing numbers of procedures began to be performed, and in several centers, it is now offered as a standard of care option alongside surgical repair.

  • The study investigated pollution intensity and heavy metals in soil at Aksaray University, revealing varying pH levels affecting metal mobility.
  • It found that 75% of the campus area is moderately to highly polluted, particularly in student-heavy areas where lead (Pb) is concentrated.
  • Analysis showed that over half of the pollution comes from natural sources, with significant contributions from industrial and traffic activities, highlighting the need for ongoing monitoring of heavy metals on campus.

Objective: Postoperative junctional ectopic tachycardia (JET) is usually a self-limiting condition; however, when combined with atrioventricular dissociation and postoperative ventricular dysfunction, it may increase morbidity and mortality. This study aimed to determine the overall incidence of JET following congenital heart surgery, to identify patient and procedure-related risk factors, and to evaluate the clinical impact of JET on outcomes.

Methods: The records of 2,814 patients who underwent cardiac surgery over a five-year period were reviewed retrospectively to identify those with JET.

  • The study investigates the impact of physical activity (PA) on sedentary behavior and body measurements in children and adolescents, highlighting a trend where physical activity decreases and sedentary time increases with age.
  • In a sample of 759 participants aged 6-17, results revealed children are less sedentary and more active than adolescents, with significant differences in body composition measurements based on physical activity levels.
  • The findings suggest that physically active individuals, especially boys, had lower body fat percentages and slimmer skinfold measurements compared to inactive peers, indicating that engaging in recommended levels of PA may mitigate obesity risks.
