The 2019 Advancing American Kidney Health (AAKH) initiative aims to increase utilization of home dialysis for end-stage kidney disease (ESKD), but its impact on public awareness is unknown. We analyzed Google Trends data from 2013-2021 to compare relative search volumes for "home dialysis", "peritoneal dialysis", and "home hemodialysis" in the United States (US) versus globally before versus after the July 2019 AAKH announcement. An interrupted time-series analysis found steady pre-AAKH increases in search interest across terms and locations.

During a health emergency, there is an urgent need to rapidly develop guidelines that meet minimum quality standards, as exemplified by the development of WHO guidelines on mask use in health care and community settings during the COVID-19 pandemic. Between January 2020 and October 2023, WHO developed 21 guideline updates on the use of masks as part of infection prevention and control (IPC) practices. Guideline developers had to deal with an ever-growing volume of evidence of variable quality.

Background: Point-of-care (PoC) hepatitis B virus (HBV) DNA viral load (VL) assays represent an alternative to laboratory-based standard-of-care (SoC) VL assays to accelerate diagnosis and treatment. We evaluated the impact of using PoC versus SoC approaches on the uptake of VL testing, treatment, and turnaround times from testing to treatment across the HBV care cascade.

Methods: We searched 5 databases, 6 conference websites, and contacted manufacturers for unpublished reports, for articles with or without a comparator (SoC VL testing), and had data on the uptake of VL testing, treatment, or turnaround times between hepatitis B surface antigen (HBsAg) testing, VL testing, and treatment in the cascade.

Article Synopsis
  • The study investigates "spin," which is the misleading representation of research findings, particularly focusing on harmful outcomes in systematic reviews of interventions.
  • Researchers created a framework to spot and analyze twelve specific types of spin related to harms, categorizing them into reporting, interpretation, and extrapolation.
  • Through their analysis of 100 systematic reviews, they found significant instances of spin, notably in inappropriate extrapolation, and provided revised examples and guidance for improving harm reporting accuracy in research publications.

Importance: The United States Preventive Services Task Force (USPSTF) has considered the topic of prevention of child maltreatment multiple times over its nearly 40-year history, each time reaching the conclusion that the evidence is insufficient to recommend for or against interventions aimed at preventing this important health problem with significant negative sequelae before it occurs. In the most recent evidence review, which was conducted from August 2021 to November 2023 and published in March 2024, the USPSTF considered contextual questions on the evidence for bias in reporting and diagnosis of maltreatment in addition to key questions regarding effectiveness of interventions to prevent child maltreatment.

Observations: A comprehensive literature review found evidence of inaccuracies in risk assessment and racial and ethnic bias in the reporting of child maltreatment and in the evaluation of injuries concerning for maltreatment, such as skull fractures.

Background: Definitions of long COVID are evolving, and optimal models of care are uncertain.

Purpose: To perform a scoping review on definitions of long COVID and provide an overview of care models, including a proposed framework to describe and distinguish models.

Data Sources: English-language articles from Ovid MEDLINE, PsycINFO, the Cochrane Library, SocINDEX, Scopus, Embase, and CINAHL published between January 2021 and November 2023; gray literature; and discussions with 18 key informants.

Background: Clinical and public health guidelines serve to direct clinical practice and policy, based on the best available evidence. The World Health Organization (WHO) and national health bodies of many countries have released physical activity and sedentary behaviour guidelines. Despite significant overlap in the body of evidence reviewed, the guidelines differ across jurisdictions.

Article Synopsis
  • * The review evaluated interventions that could be implemented in primary care settings, focusing on randomized clinical trials involving children or their caregivers with no maltreatment history.
  • * Results from 25 trials indicated no significant differences in reports to Child Protective Services or child removal from homes after interventions, suggesting that current preventive strategies might not be effective in the short term.

Purpose: The summary presented herein covers recommendations on salvage therapy for recurrent prostate cancer intended to facilitate care decisions and aid clinicians in caring for patients who have experienced a recurrence following prior treatment with curative intent. This is Part I of a three-part series focusing on treatment decision-making at the time of suspected biochemical recurrence (BCR) after radical prostatectomy (RP). Please refer to Part II for discussion of treatment delivery for non-metastatic BCR after RP and Part III for discussion of evaluation and management of recurrence after radiotherapy (RT) and focal therapy, regional recurrence, and oligometastasis.

Background And Aims: We evaluated the effectiveness and safety of pan-genotypic regimens, glecaprevir/pibrentasvir (GLE/PIB), sofosbuvir/velpatasvir (SOF/VEL), and sofosbuvir/daclatasvir (SOF/DCV) and other direct-acting antivirals (DAA) regimens for the treatment of hepatitis C virus (HCV)-infected adolescents (12-18 years), older children (6-11 years), and young children (3-5 years). The purpose of this systematic review and meta-analysis was to inform the World Health Organization (WHO) guidelines.

Methods: We included clinical trials and observational studies published up to August 11, 2021, that evaluated DAA regimens in HCV-infected adolescents, older children, and young children.

Synopsis of recent research by authors named "Roger Chou"

  • - Roger Chou's recent research primarily focuses on systematic reviews and meta-analyses related to critical health issues, such as evaluating diagnostic accuracy and treatment efficacy for conditions affecting vulnerable populations, particularly young infants and pregnant women.
  • - Key findings from his studies highlight the need to improve point-of-care testing for hepatitis B to enhance treatment uptake and reduce turnaround times, as well as the necessity of refining screening and supplementation strategies for iron deficiency anemia during pregnancy and for effectively managing infections in young infants.
  • - Additional investigations include the development of frameworks to identify reporting biases (“spin”) in systematic reviews and addressing evidence gaps in child maltreatment prevention strategies, emphasizing the importance of accurate reporting and intervention effectiveness.
