Autophagy is the cell biology process in which cytoplasmic components are degraded in lysosomes to maintain cellular homeostasis and energy production. In the healthy kidney, autophagy plays an important role in the homeostasis and viability of renal cells such as podocytes and tubular epithelial cells and of immune cells. Recently, evidence is mounting that (dys)regulation of autophagy is implicated in the pathogenesis of various renal diseases, and might be an attractive target for new renoprotective therapies. In this review, we provide an overview of the role of autophagy in kidney physiology and kidney diseases.

The need for standardized language is increasingly obvious, also within gastrointestinal endoscopy. A systematic approach to the description of endoscopic findings is vital for the development of a universal language, but systematic also means structured, and structure is inherently a challenge when presented as an alternative to the normal spoken word. The efforts leading to the "Minimal Standard Terminology" (MST) of gastrointestinal endoscopy offer a standardized model for description of endoscopic findings. With a combination of lesion descriptors and descriptor attributes, this system gives guidance to appropriate descriptions of lesions and also has a normative effect on endoscopists in training. The endoscopic report includes a number of items not related to findings per se, but to other aspects of the procedure, formal, technical, and medical. While the MST sought to formulate minimal lists for some of these aspects (e.g. indications), they are not all well suited for the inherent structure of the MST, and many are missing. Thus, the present paper offers a recommended standardization also of the administrative, technical, and other "peri-endoscopic" elements of the endoscopic report; important also are the numerous quality assurance initiatives presently emerging. Finally, the image documentation of endoscopic findings is becoming more obvious-and accessible. Thus, recommendations for normal procedures as well as for focal and diffuse pathology are presented. The recommendations are "minimal," meaning that expansions and subcategories will likely be needed in most centers. Still, with a stronger common grounds, communication within endoscopy will still benefit.

Background Digital interventions based on cognitive–behavioural therapy and relapse prevention can increase treatment access for people with problematic alcohol use, but for these interventions to be cost-effective, clinician workload needs to remain low while ensuring patient adherence and effects. Digital psychological self-care is the provision of a self-guided digital intervention within a structured care process. Aims To investigate the feasibility and preliminary effects of digital psychological self-care for reducing alcohol consumption. Method Thirty-six adults with problematic alcohol use received digital psychological self-care during 8 weeks, including telephone assessments as well as filling out self-rated questionnaires, before, directly after and 3 months after the intervention. Intervention adherence, usefulness, credibility and use of clinician time were assessed, along with preliminary effects on alcohol consumption. The study was prospectively registered as a clinical trial (NCT05037630). Results Most participants used the intervention daily or several times a week. The digital intervention was regarded as credible and useful, and there were no reported adverse effects. Around 1 h of clinician time per participant was spent on telephone assessments. At the 3-month follow-up, preliminary within-group effects on alcohol consumption were moderate (standardised drinks per week, Hedge's g = 0.70, 95% CI = 0.19–1.21; heavy drinking days, Hedge's g = 0.60, 95% CI = 0.09–1.11), reflecting a decrease from 23 to 13 drinks per week on average. Conclusions Digital psychological self-care for reducing alcohol consumption appears both feasible and preliminarily effective and should be further optimised and studied in larger trials.
