Previous research has linked female weight concerns and smoking. This study examined whether poor body image and other eating disorder variables, after controlling for symptoms of anxiety and depression, were predictive of smoking severity in a sample of 478 college students (n=215 males, n=246 females). Contrary to our hypotheses and recent research, the predictors were not associated with nicotine dependence for females (R(2)=.00), and only dieting was negatively associated with nicotine dependence for males. These findings might be attributable to differences in how nicotine dependence is operationalized, the use of point prevalence symptom data versus lifetime prevalence of psychopathology, the severity of psychopathology in the present sample, or the use of a cross-sectional as opposed to a longitudinal design.

Phase separation is essential for membrane function, and alterations in phase coexistence by membrane-interacting molecules, such as nicotine, can impair membrane stability. With the increasing use of e-cigarettes, concerns have arisen about the impact of nicotine on pulmonary surfactants. Here, we used differential scanning calorimetry (DSC), molecular dynamics (MD) simulations, and electron spin resonance (ESR) to examine nicotine's effect on the phase coexistence of two surfactant models: pure DPPC and a DPPC/POPC/POPG mixture.

Ventricular assist device (VAD) and cardiac transplant patients experience significant strain on their physical and mental wellbeing postoperatively. Mental health and substance use disorders (MHDs and SUDs) have substantial effects on the quality of life and compliance of transplant and VAD patients. In this study, we compare and characterize MHDs and SUDs between VAD and cardiac allograft patients and transplant list patients with and without VADs.

Introduction: Tobacco smoking remains a leading cause of ill-health, premature mortality and a driver of health inequalities. To support smokers in England, a comprehensive approach to treating tobacco dependence is being implemented. This includes offering support to all people admitted to hospitals, as well as women and pregnant people within NHS settings.

Introduction: Improved effectiveness and treatment adherence is needed in smoking cessation (SC) therapies. Another important challenge is to disrupt maladaptive drug-related memories. To achieve these goals, we developed a novel treatment strategy on the basis of motion-assisted memory desensitization and reprocessing (3MDR).
