Feasibility and acceptability of study methods and psychosocial interventions for body image among women diagnosed with breast cancer: A systematic review and narrative synthesis.

Objective: This systematic review aimed to summarize evidence for the feasibility and acceptability of psychosocial interventions for body image among women diagnosed with breast cancer and the study methods used to evaluate the interventions in question.

Methods: Articles were identified via MEDLINE, CINAHL, CENTRAL, PsychINFO, and EMBASE. Inclusion criteria were: (1) peer-reviewed publication in English from 2000 onward with accessible full-text, (2) reported data on the feasibility and/or acceptability of psychosocial interventions and/or study methods, (3) included at least one measure of body image or reported a body-related theme, and (4) sample comprised women diagnosed with breast cancer.

Autophagy impairment and lifespan reduction caused by Atg1 RNAi or Atg18 RNAi expression in adult fruit flies (Drosophila melanogaster).

Autophagy, an autophagosome and lysosome-based eukaryotic cellular degradation system, has previously been implicated in lifespan regulation in different animal models. In this report, we show that expression of the RNAi transgenes targeting the transcripts of the key autophagy genes Atg1 or Atg18 in adult fly muscle or glia does not affect the overall levels of autophagosomes in those tissues and does not change the lifespan of the tested flies but the lifespan reduction phenotype has become apparent when Atg1 RNAi or Atg18 RNAi is expressed ubiquitously in adult flies or after autophagy is eradicated through the knockdown of Atg1 or Atg18 in adult fly adipocytes. Lifespan reduction was also observed when Atg1 or Atg18 was knocked down in adult fly enteroblasts and midgut stem cells.
