Beyond the Usual Significance: Fragility Indices of Randomized Controlled Trials in Top General Orthopaedic Journals.

Introduction: Understanding the reliability of outcomes in randomized controlled trials (RCTs) is crucial, as standard metrics, such as P- value do not fully capture result fragility. This led to the adoption of specific indices: the fragility index (FI), which measures the strength of trial through significant results by calculating the minimum number of patient status changes from nonevent to event required to make the results statistically insignificant; reverse fragility index (RFI), used for insignificant results; and continuous fragility index (CFI), which acts similar to FI for significant continuous outcomes. The objective is to assess the robustness of orthopaedics RCTs using these indices across leading orthopaedic journals.

Elevated levels of pro-thrombotic eNOS-negative platelets in COVID-19 patients.

Background: Platelet-rich microvascular thrombi are common in severe COVID-19. Endogenous nitric oxide (NO)-signaling limits thrombus formation and previously we identified platelet subpopulations with a differential ability to produce NO based on the presence or absence of endothelial nitric oxide synthase (eNOS). eNOS expression is counter-regulated by cytokines, and COVID-19-associated immune/inflammatory responses may affect the transcriptome profile of megakaryocytes and their platelet progeny.

Feeding pomegranate pulp to Ghezel lambs for enhanced productivity and meat quality.

Agrifood by-products contain nutrients and bioactive compounds that can be used in the diets of livestock - thereby value-adding to an otherwise waste product of environmental and economic significance. This study investigated the effect of dietary pomegranate pulp in the total mixed ration of Ghezel lambs, evaluating its effect on growth performance, blood parameters, carcass traits, as well as meat quality and shelf life. 3-month-old Ghezel lambs (individually housed, = 8) were randomly assigned to be either non-supplemented (control) or supplemented with 100 g/kg DM of sun-dried pomegranate pulp for 28 days, post-adjustment.

Performance and optimization study of selected 4-terminal tandem solar cells.

Tandem solar cells owing to their layered structure in which each sub-cell utilizes a certain part of the solar spectrum with reduced thermal losses, are promising applicants to promote the power conversion efficiency beyond the Shockley-Queisser limit of single-junction solar cells. This study delves into the performance and optimization of 4-terminal organic/silicon tandem solar cells through numerical simulations using SCAPS-1D software. The tandem architecture combining organic, perovskite, and silicon materials, shows potential in enhancing light absorption across the solar spectrum with complementary absorption spectra.

Blood Pressure and Mortality in the 4D Study.

Introduction: Systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) are risk factors for cardiovascular mortality (CVM). Pulse pressure (PP) is an easily available parameter of vascular stiffness, but its impact on CVM in chronic dialysis patients with diabetes is unclear.

The experiences of psychiatric patients, their caregivers and companions in upholding patient dignity during hospitalization: A qualitative study.

Introduction: The quality of care and patient satisfaction is closely linked with dignity, which is a crucial component of therapy and care. However, there is very little study on dignity in the context of mental health care. Planning for ongoing patient care might benefit from an understanding of the notion of dignity by exploring the experiences of patients, caregivers and companions of patients who have a history of hospitalization in mental health institutions.

Role of Nitric Oxide in Megakaryocyte Function.

Megakaryocytes are the main members of the hematopoietic system responsible for regulating vascular homeostasis through their progeny platelets, which are generally known for maintaining hemostasis. Megakaryocytes are characterized as large polyploid cells that reside in the bone marrow but may also circulate in the vasculature. They are generated directly or through a multi-lineage commitment step from the most primitive progenitor or Hematopoietic Stem Cells (HSCs) in a process called "megakaryopoiesis".
