Introduction: GRADE and other Evidence to Decision (EtD) frameworks are widely used by guideline development groups (GDG) and other decision-makers. When GDGs judge the magnitude of desirable and undesirable health outcomes on EtDs, they typically categorize them as trivial, small, moderate or large. However, generic judgment or decision thresholds (DTs) that could guide the user about such estimates of effect size or serve as references for interpretation of findings are not yet available.

Stroke in critically ill patients with respiratory failure due to COVID-19: Disparities between low-middle and high-income countries.

Heart Lung

October 2024

Division of Neuroscience Critical Care, Departments of Neurology, Neurosurgery, and Anesthesiology and Critical Care Medicine, Johns Hopkins University School of Medicine, Baltimore, MD, USA.

Article Synopsis
  • A study was conducted to compare stroke incidences and mortality rates in critically ill COVID-19 patients from low-and middle-income countries (LMICs) and high-income countries (HICs).
  • The results showed that stroke incidence was significantly higher in LMICs (35.7 per 1000 admitted-days) compared to HICs (17.6 per 1000 admitted-days), with patients from LMICs also facing higher mortality rates (43.6% vs. 29.2%).
  • The findings highlight the need for better stroke diagnosis and healthcare resource allocation in LMICs, as both higher income status and the presence of stroke are associated with increased risk of death

Article Synopsis
  • The study investigates how common cerebrovascular events (CVEs) are in patients diagnosed with primary systemic vasculitis (PSV) and identifies factors linked to these events.
  • It involved analyzing data from over 4,800 adults with PSV, revealing that 3.50% experienced CVEs, primarily strokes and transient ischemic attacks (TIAs), with the highest rates in certain types of vasculitis like Behçet's disease.
  • The findings highlight that CVEs are prevalent among PSV patients, vary significantly depending on the type of vasculitis, and recur at a high rate, indicating that traditional vascular risk factors do not account for these events.

This study aimed to report quality of life (QoL) scores in unilateral cochlear implant (CI) users and to generate guidance for clinicians on using QoL measures to individualize CI counselling and rehabilitation and to increase access to CIs as a mode of rehabilitation. Participants (n = 101) were unilateral CI users with single-sided deafness (SSD; n = 17), asymmetrical hearing loss (AHL; n = 26), or bilateral hearing loss (Uni; n = 58). Generic QoL was assessed via the Health Utilities Index (HUI-3), and disease-specific QoL was assessed via the Speech, Spatial, and Qualities of Hearing scale (SSQ12) and Nijmegen CI Questionnaire (NCIQ) at preimplantation and at 6 and 12 months of CI use.

Although Microrchidia 2 (MORC2) is widely overexpressed in human malignancies and linked to cancer cell proliferation, metabolism, and metastasis, the mechanism of action of MORC2 in cancer cell migration and invasion is yet undeciphered. Here, we identified for the first time that MORC2, a chromatin remodeler, regulates E-cadherin expression and, subsequently regulates breast cancer cell migration and invasion. We observed a negative correlation between the expression levels of MORC2 and E-cadherin in breast cancer.
