Generalized Linear Models with Covariate Measurement Error and Zero-Inflated Surrogates.

Epidemiological studies often encounter a challenge due to exposure measurement error when estimating an exposure-disease association. A surrogate variable may be available for the true unobserved exposure variable. However, zero-inflated data are encountered frequently in the surrogate variables.

Diet Matters in Breast Cancer Prognosis: Clinical Trial Evidence and Questions.

Diet and weight matter in breast cancer prognosis. The DIANA-5 randomized controlled trial found no effect of a Mediterranean macrobiotic diet on 5-year breast cancer recurrence, but high adherence was associated with a 41% lower risk of recurrence versus controls. The effects of substantial weight loss on prognosis remain unknown.

Exploring anxiety as an influencing factor of the impact of exercise and mind-body prehabilitation on cognitive functioning among women undergoing breast cancer surgery.

Objective: The purpose of this secondary analysis was to describe the prevalence of anxiety, depression, and perceived stress among women newly diagnosed with breast cancer and the impact of baseline and changes in anxiety on cognitive functioning following exercise and mind-body prehabilitation interventions.

Methods: The sample consisted of 49 women with newly diagnosed breast cancer (stages I-III) who planned to undergo breast cancer surgery at two academic cancer centers. Participants were randomized to receive an exercise or mind-body prehabilitation intervention between the time of diagnosis and breast cancer surgery.

Assisted vaginal delivery in the obese patient.

Appropriate use of ventouse or obstetric forceps as options in the management of the second-stage of labor is good medical practice. The instruments are not inherently dangerous, however, the manner in which they are used may be. In addition to a working knowledge of the instruments, the operator must have the willingness to abandon an unsuccessful procedure.

Eating disorders in weight-related therapy (EDIT): Protocol for a systematic review with individual participant data meta-analysis of eating disorder risk in behavioural weight management.

The Eating Disorders In weight-related Therapy (EDIT) Collaboration brings together data from randomised controlled trials of behavioural weight management interventions to identify individual participant risk factors and intervention strategies that contribute to eating disorder risk. We present a protocol for a systematic review and individual participant data (IPD) meta-analysis which aims to identify participants at risk of developing eating disorders, or related symptoms, during or after weight management interventions conducted in adolescents or adults with overweight or obesity. We systematically searched four databases up to March 2022 and clinical trials registries to May 2022 to identify randomised controlled trials of weight management interventions conducted in adolescents or adults with overweight or obesity that measured eating disorder risk at pre- and post-intervention or follow-up.
