Lingual Artery Identification for Ligation in Neck Dissection and Transoral Surgery for Oropharyngeal Tumors.

Objectives: Transoral robotic surgery (TORS) and transoral laser microsurgery (TOLM) plus neck dissection are viable alternatives to radiotherapy as a treatment modality in select cases of oropharyngeal squamous cell carcinoma. Many centers advocate for elective ligation of the feeding arteries at index neck dissection prior to TORS/TOLM to mitigate the risk of catastrophic perioperative hemorrhage. Although there are multiple cadaveric studies in the literature to identify the lingual artery at multiple points throughout its course, there are no studies on the intraoperative identification of the lingual artery for elective ligation prior to TORS/TOLM.

Ecological and demographic drivers of kin-directed cooperation in a social bird: Insights from a long-term study.

The evolution of sociality is one of the major evolutionary transitions in the history of life and a key step in this transition is the occurrence of kin associations. Yet, the question of what demographic processes and environmental factors generate kin-structured populations and drive kin-directed cooperation remains open. In this review, we synthesise 30 years of studies of the long-tailed tit Aegithalos caudatus, which has a kin-selected cooperative breeding system with redirected help: failed breeders may help to raise offspring of conspecifics, typically relatives, breeding nearby.

Standardized Measurement of Type 1 Diabetes Polygenic Risk Across Multi-Ancestry Population Cohorts.

Type 1 diabetes (T1D) polygenic risk scores (PRS) are effective tools for discriminating T1D from other diabetes types and predicting T1D risk, with applications in screening and intervention trials. A previously published T1D Genetic Risk Score 2 (GRS2) is widely adopted, but challenges in standardization and accessibility have hindered broader clinical and research utility. To address this, we introduce GRS2x, a standardized and cross-compatible method for accurate T1D PRS calculation, demonstrating genotyping and reference panel independent performance across diverse datasets.

Glucose Lowering through Weight management (GLoW): a randomised controlled trial of the clinical and cost effectiveness of a diabetes education and behavioural weight management programme vs a diabetes education programme in adults with a recent diagnosis of type 2 diabetes.

Aims/hypothesis: UK standard care for type 2 diabetes is structured diabetes education, with no effects on HbA, small, short-term effects on weight and low uptake. We evaluated whether remotely delivered tailored diabetes education combined with commercial behavioural weight management is cost-effective compared with current standard care in helping people with type 2 diabetes to lower their blood glucose, lose weight, achieve remission and improve cardiovascular risk factors.

Methods: We conducted a pragmatic, randomised, parallel two-group trial.

The genome sequence of the white-throated dipper, (Linnaeus, 1758).

We present a genome assembly from a juvenile male (the white-throated dipper; Chordata; Aves; Passeriformes; Cinclidae). The genome sequence has a total length of 1,170.80 megabases.
