GRADE Certainty Ratings: Thresholds Rather Than Categories of Contextualization (GRADE Guidance 41).

In 2017, the GRADE (Grading of Recommendations Assessment, Development and Evaluation) working group defined the certainty of evidence as the certainty that the true effect lies on one side of a threshold or in a particular range. This definition has proved useful as the basis for rating certainty, facilitating the interpretation of the results for the target audience. However, the categorization of suggested thresholds and ranges as levels of contextualization led to inconsistencies between the initial and subsequent papers and has proved confusing for some GRADE users.

Effects of the SGLT2 inhibitor dapagliflozin in early Alzheimer's disease: A randomized controlled trial.

Introduction: Due to its metabolic effects, dapagliflozin, a sodium-glucose transporter 2 (SGLT2) inhibitor, holds potential as an Alzheimer's disease (AD) therapeutic.

Methods: We conducted a double-blind, randomized, placebo-controlled, parallel-group, 12-week single-site study to investigate the effect of dapagliflozin in participants with probable AD (Mini-Mental State Examination [MMSE] score 15-26). We planned to enroll 48 participants with 2:1 randomization to 10 mg dapagliflozin once daily (n = 32) versus matching placebo (n = 16).

This study aimed to evaluate the impact of oral administration of CECT5713 on pregnancy success rates in couples with unexplained infertility prior to in vitro fertilization (IVF).

Hydromorphone Hopes: A Qualitative Study of People Initiating Supervised Short-Acting Injectable Opioid Treatment in Australia.

Introduction: A growing body of qualitative scholarship has drawn attention to aspects of supervised injectable opioid treatment (SIOT) not captured in earlier clinical trial data, identifying treatment initiation as one such area. Crucial questions surrounding people's motivations, expectations and initial experiences of SIOT remain under-explored. This paper examines the first tranche of qualitative findings from participants of Australia's first-ever SIOT trial, the 'Feasibility of Opioid Injectable Treatment' (FOpIT) study.

Real-World Postural Transitions as Biomarkers of Functional Impairment in Duchenne Muscular Dystrophy.

Duchenne muscular dystrophy (DMD) is a progressive neuromuscular disorder that impairs daily functioning and results in premature death. Current clinical assessments are widely used for characterizing functional impairment but have limitations due to their subjective and effort-based nature and because they only capture a snapshot of symptoms at a single point in time. Digital health technologies, such as wearable devices, allow continuous collection of movement and physiological data during daily life and could provide objective measures of the impact of DMD symptoms on daily functioning.

Targeted p38 mitogen-activated protein kinase inhibition potently augment inflammatory responses of human macrophages toward Staphylococcus aureus.

ADORE: an open platform study of ruxolitinib in combination with other novel therapies in patients with myelofibrosis.

Ruxolitinib, a Janus kinase (JAK)1/JAK2 inhibitor, is the standard of care for symptomatic patients with myelofibrosis (MF). However, ∼70% of patients discontinue ruxolitinib after ∼5 years, a third of whom report suboptimal splenic response. ADORE was a phase 1b/2 study with an innovative open platform design that assessed the safety, efficacy, and pharmacokinetics of novel compounds in combination with ruxolitinib in patients with MF who had a suboptimal response to ruxolitinib alone.

A hidden cysteine in Fis1 targeted to prevent excessive mitochondrial fission and dysfunction under oxidative stress.

Fis1-mediated mitochondrial localization of Drp1 and excessive mitochondrial fission occur in human pathologies associated with oxidative stress. However, it is not known how Fis1 detects oxidative stress and what structural changes in Fis1 enable mitochondrial recruitment of Drp1. We find that conformational change involving α1 helix in Fis1 exposes its only cysteine, Cys41.

Lower locus coeruleus integrity is associated with diminished practice effects in clinically unimpaired older individuals.

The locus coeruleus (LC), one of the earliest structures affected by tau pathology in Alzheimer's disease (AD), plays an important role in modulating arousal and learning. In asymptomatic early stages of AD, more sensitive measures to identify subtle cognitive changes are needed. Previous studies indicate that practice effects can signal initial AD-related learning deficits.
