News|Articles|October 19, 2026 In patients 45+ with papillary thyroid cancer, men with dual BRAF V600E and TERT promoter mutations face sharply higher mortality, reshaping risk stratification. Male sex was associated with higher papillary thyroid cancer (PTC)-specific mortality among patients aged 45 years or older whose tumors harbored concurrent BRAF V600E and TERT promoter (TERTp) mutations, according to an international multicenter cohort study published in JAMA Network Open.1Among patients aged 45 years or older with both mutations, male sex was associated with a 3-fold higher risk of PTC-specific mortality after adjustment for clinicopathologic factors (adjusted HR, 3.07; 95% CI, 1.35-6.97; P =.007). This group also had the highest observed mortality rate, at 37.07 deaths per 1000 person-years, highlighting the prognostic relevance of evaluating these biological factors together. Study Design and Patient CharacteristicsThe retrospective cohort study included 4746 patients with PTC treated at 15 medical centers across 10 countries between 1979 and 2023. The median patient age was 48 years (IQR, 37-59), and 3612 patients (76.1%) were women.

Magnitude of Thyroid Disorders in Patients with Abnormal Uterine Bleeding - Cureus
Background: Abnormal uterine bleeding (AUB) is a common gynaecological complaint, and thyroid dysfunction may contribute to menstrual abnormalities. This study evaluated the prevalence of thyroid dysfunction among women presenting with AUB and its association with clinical characteristics. Methods: This observational study was conducted in the Department of Obstetrics and Gynaecology, Kempegowda Institute of Medical Sciences, Bengaluru, India, from January 2020 to June 2021. It included 100 women with AUB. Demographic and clinical data, such as age, parity, body mass index (BMI), type and duration of AUB, thyroid status, family history, and goitre and thyroid-related symptoms, were documented. Thyroid function tests were used to group the participants into the following categories: euthyroid, subclinical, hypothyroid, and hyperthyroid. Results: The mean age was 34.85 ± 8.29 years, and the mean BMI was 24.74 ± 3.36 kg/m². Thyroid dysfunction was found to be present in 20% of the participants. Heavy menstrual bleeding was the most common AUB pattern (40%), which was not significantly associated with thyroid status (p = 0.398). Significant associations were observed between thyroid st
Study reveals mature immune functions in embryonic neutrophils - News-Medical
Neutrophils are white blood cells that form part of the body's first line of defence. Researchers have now demonstrated for the first time that neutrophils are found in many tissues during embryonic development, and that they can perform the same functions as adult neutrophils. The findings warrant further study on the role of embryonic neutrophils in tissue development and in responding to infections in fetuses and newborns. Neutrophils are part of innate immune defence. When inflammation occurs, they rapidly migrate from the bloodstream into tissues to eliminate harmful microbes. Their role is well understood in adults, but remarkably little is known about embryonic neutrophils.
