Lessons Learned from a Quality Improvement Initiative to Increase COVID-19 Vaccination in Hospitalized Children.

Introduction: Pediatric coronavirus disease 2019 (COVID-19) vaccination rates in the United States remain lower compared with adults. We aimed to (1) implement a quality improvement initiative to increase COVID-19 vaccination 2-fold in hospitalized patients 12-21 years of age from 4.7% during the baseline period (August 10, 2021-November 1, 2021) to 9.

An examination of sugar-sweetened beverage tax regulations in six jurisdictions: Applying a social justice perspective to beverage taxation and exemptions.

Taxes, legislation and politics are social determinants of health, which can impact health through multiple pathways. The purpose of this study was to review regulations regarding sugar-sweetened beverage (SSB) taxation and describe taxation/exemption of various beverage categories. We reviewed SSB taxation regulations from Mexico, the United Kingdom, Berkeley, Philadelphia, San Francisco and South Africa.

Increasing access to mental health supports for 12-17-year-old Indigenous youth with the JoyPop mobile mental health app: study protocol for a randomized controlled trial.

Background: Indigenous youth in Northwestern Ontario who need mental health supports experience longer waits than non-Indigenous youth within the region and when compared to youth in urban areas. Limited access and extended waits can exacerbate symptoms, prolong distress, and increase risk for adverse outcomes. Innovative approaches are urgently needed to provide support for Indigenous youth in Northwestern Ontario.

ANGPTL3 Deficiency and Risk of Hepatic Steatosis.

Background: ANGPTL3 (angiopoietin-like 3) is a therapeutic target for reducing plasma levels of triglycerides and low-density lipoprotein cholesterol. A recent trial with vupanorsen, an antisense oligonucleotide targeting hepatic production of ANGPTL3, reported a dose-dependent increase in hepatic fat. It is unclear whether this adverse effect is due to an on-target effect of inhibiting hepatic ANGPTL3.

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.
