Genome-wide association study of varenicline-aided smoking cessation.
Nicotine Tob Res
January 2025
Department of Population Health Sciences, University of Leicester, Leicester, UK.
Introduction: Varenicline is an α4β2 nicotinic acetylcholine receptor partial agonist with the highest therapeutic efficacy of any pharmacological smoking cessation aid and a 12-month cessation rate of 26%. Genetic variation may be associated with varenicline response, but to date no genome-wide association studies of varenicline response have been published.
Methods: In this study, we investigated the genetic contribution to varenicline effectiveness using two electronic health record-derived phenotypes.

Type II nuclear receptors (T2NRs) require heterodimerization with a common partner, the retinoid X receptor (RXR), to bind cognate DNA recognition sites in chromatin. Based on previous biochemical and overexpression studies, binding of T2NRs to chromatin is proposed to be regulated by competition for a limiting pool of the core RXR subunit. However, this mechanism has not yet been tested for endogenous proteins in live cells.

The scientific evidence supporting recommendations for dietary supplement use to prevent or treat coronavirus disease 2019 (COVID‑19) is not well‑established. This cohort study investigates the relationship between dietary supplement usage and COVID‑19 symptoms among 27,181 adults tested for COVID‑19. Using data from surveys following COVID‑19 testing, conducted by the University of Arkansas for Medical Sciences, associations between dietary supplement usage, symptomatology, and COVID‑19 status were explored.

Department of Gastroenterology, Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine, Nanjing, Jiangsu, China.
Aim: The tumor microenvironment in pancreatic cancer, characterized by abundant desmoplastic stroma, has been implicated in the failure of chemotherapy. Therefore, developing therapeutic strategies targeting tumor and stromal cells is essential. Triptolide, a natural compound derived from the plant Tripterygium wilfordii, has shown antitumor activity in various cancers, including pancreatic cancer.

Author Affiliations: Department of Nursing, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine (Dr Kim); and College of Nursing, Hanyang University (Dr Hwang), Seoul, Republic of Korea.
Background: Although the survival rate for thyroid cancer is high, a nursing intervention that enhances autonomous motivation is needed for patients with jobs to improve their long-term self-management abilities in the early postoperative period.
Objectives: This study aims to develop a mobile application (app) based on the Self-Determination Theory for patients returning to work after thyroid cancer surgery and to verify its effectiveness.
Methods: We developed an app to promote self-management and verify its effectiveness after 12 weeks in early outpatients who underwent thyroid cancer surgery through a randomized controlled trial design.
