The objective of this meta-epidemiological study was to develop a rating that captures participants' motivation at the study level in digital health intervention (DHI) randomised controlled trials (RCTs). The rating was used to investigate whether participants' motivation is associated with the effect estimates in DHI RCTs for cancer patients. The development of the rating was based on a bottom-up approach involving the collection of information that captures participants' baseline motivation in empirical studies from the Smartphone-RCCT Database.

Article Synopsis
  • The study investigates the CD4/CD8 ratio as a possible marker for mortality risk in people living with HIV, highlighting its potential significance compared to CD4 counts alone.
  • A systematic review and meta-analysis were conducted, analyzing data from 20 studies, revealing that a low CD4/CD8 ratio (below 0.5) correlates with a significantly higher mortality risk.
  • While the analysis couldn't confirm a clear trend regarding CD8+ T-cell counts, it suggests that high counts may negatively affect long-term outcomes, emphasizing the need for standardized measurement protocols in future research.*

Article Synopsis
  • - The study investigates the effectiveness of four biomarkers (procalcitonin, C-reactive protein, interleukin-6, and presepsin) in predicting mortality in critically ill adults with sepsis, addressing inconsistencies found in previous research.
  • - A systematic review and meta-analysis of 60 studies involving over 15,000 patients revealed a high risk of bias in more than 60% of assessments for these biomarkers as prognostic indicators.
  • - The findings indicate that baseline measurements of these biomarkers do not reliably predict mortality outcomes, suggesting that their role in sepsis prognosis may be limited.

Objectives: To revise a sex and gender appraisal tool for systematic reviews (SGAT-SR) and apply it to Cochrane sepsis reviews.

Study Design And Setting: The revision process was informed by existing literature on sex, gender, intersectionality, and feedback from an expert advisory board. We revised the items to consider additional factors associated with health inequities and appraised sex and gender considerations using the SGAT-SR-2 and female Participation-to-Prevalence Ratio (PPR) in Cochrane sepsis reviews.

Article Synopsis
  • - The study aimed to determine if sex is an independent factor influencing mortality rates in ICU patients with sepsis through a systematic review and meta-analysis of existing research.
  • - The analysis included 13 studies with over 80,000 participants but found no significant sex-based differences in overall hospital or ICU mortality, although it indicated that females had a higher risk of 28-day mortality but a lower risk of 1-year mortality.
  • - Overall, the findings suggest that the effect of sex on mortality is uncertain, with concerns about the quality and consistency of the evidence affecting conclusions.

Introduction: Sepsis is a leading cause of mortality in critically ill patients. Recently, it has been recognised that sex may contribute to a differential risk for developing sepsis and it remains uncertain if the prognosis of sepsis varies between the sexes. The aim of this systematic review is to summarise the available evidence to assess the role of sex as a prognostic factor in patients with sepsis managed in the intensive care unit (ICU).
