A Framework to Optimize Primary Care of Older Surgical Patients: A Qualitative Study of Geriatricians.

Importance: An increasing number of older adults are undergoing surgery. Older adults face significant challenges throughout the spectrum of perioperative care. No frameworks exist to support primary care clinicians in helping older adults navigate perioperative care beyond preoperative medical clearance.

Impact of Hormonal Contraceptives on HPV Dynamics in Adolescent Girls and Young Women: Insights from a Randomized Controlled Sub-Study in South Africa.

Objectives: Human papillomavirus (HPV) is the leading cause of cervical cancer, with adolescent girls and young women (AGYW) in sub-Saharan Africa carrying a disproportionately high burden of infection. Hormonal contraceptives may influence HPV acquisition, persistence, and clearance, but evidence remains inconclusive. This sub-study aimed to evaluate the impact of different hormonal contraceptives on HPV prevalence and genotype distribution in AGYW.

The Anatomy of Gossip: Dissecting Dynamics and Impacts in Surgical Residency.

Background: Gossip, defined by social scientists as "evaluative talk about an absent third party," is anecdotally pervasive yet poorly understood in surgical residency programs. Gossip is known to have both positive and negative impacts. This study sought to deconstruct the role of gossip in surgical residency and evaluate its impact through the lens of surgical residents.

Nucleic acid joining enzymes: biological functions and synthetic applications beyond DNA.

DNA-joining by ligase and polymerase enzymes has provided the foundational tools for generating recombinant DNA and enabled the assembly of gene and genome-sized synthetic products. Xenobiotic nucleic acid (XNA) analogues of DNA and RNA with alternatives to the canonical bases, so-called 'unnatural' nucleobase pairs (UBP-XNAs), represent the next frontier of nucleic acid technologies, with applications as novel therapeutics and in engineering semi-synthetic biological organisms. To realise the full potential of UBP-XNAs, researchers require a suite of compatible enzymes for processing nucleic acids on a par with those already available for manipulating canonical DNA.

Smoking Cessation Smartphone App for Nondaily Smoking With Telephone Onboarding: Proof-of-Concept Randomized Controlled Trial.

Background: Nondaily smoking is a widespread and increasingly prevalent pattern of use. To date, no effective treatment approach for nondaily smoking has been identified.

Objective: This study aimed to conduct an unblinded randomized controlled trial to evaluate proof-of-concept markers of the Smiling instead of Smoking (SiS) app, a smartphone app for smoking cessation, designed specifically for people who smoke less than daily, within the framework of positive psychology.
