First popularized almost a century ago in epidemiologic research by Ronald Fisher and Jerzy Neyman, the P-value has become perhaps the most misunderstood and even misused statistical value or descriptor. Indeed, modern clinical research has now come to be centered around and guided by an arbitrary P-value of <0.05 as a magical threshold for significance, so much so that experimental design, reporting of experimental findings, and interpretation and adoption of such findings have become largely dependent on this "significant" P-value. ⋯ This article reviews the history of the P-value, the conceptual basis of P-value in the context of hypothesis testing and challenges in critically appraising clinical evidence vis-à-vis the P-value. This review is aimed at raising awareness of the pitfalls of this rigid observation of the threshold of statistical significance when evaluating clinical trials and to generate discussion regarding whether the scientific body needs a rethink about how we decide clinical significance.

Sexual harassment (SH) is a particularly harmful type of harassment that can inflict lasting psychological harm on victims. Within the healthcare sector, it negatively impacts teamwork, communication, and potentially compromises patient care. ⋯ Despite increased awareness, evidence suggests that SH remains prevalent in healthcare settings and shows no signs of decline over time. Therefore, there is an urgent need for effective training and intervention measures to enhance the identification of potential sexually offensive behaviors, thus fostering a work environment characterized by respect and inclusivity.

Previous studies have suggested relationship between diverticular disease and cardiovascular disease. Since cardiovascular disease and cerebrovascular accident share a lot of pathogenesis, diverticulitis could also be a risk factor for stroke. This study tried to establish epidemiological evidence of the relationship between colon diverticulitis and ischemic stroke. ⋯ Our study found that colon diverticulitis was associated with a higher risk of developing subsequent ischemic stroke, especially for patients aged 30-39 years, among Asian population. This result provides us a chance to undertake preventive measures for ischemic stroke in high-risk patients.

Lack of communication in a family's preferred language is inequitable and results in inferior care. Pediatric residents provide care to many families with non-English or French language preferences (NEFLP). There is no data available about how Canadian pediatric residents use interpreters, making it difficult to develop targeted interventions to improve patient experience. ⋯ Residents are more confident in their clinical and communication skills when working with families who share their primary language. Our findings suggest that residents lack the training and confidence to provide equal care to families with varying language preferences. Pediatric training programs should develop curriculum content that targets safe and effective interpreter use while reviewing non-spoken aspects of cultural awareness and safety.

The diagnosis of myasthenia gravis (MG) in children remains difficult. Circulating small extracellular vesicle (sEV)-derived miRNAs (sEV-miRNAs) have been recognized as biomarkers of various diseases and can be excreted by different cell types. These biomarker candidates also play a vital role in autoimmune diseases via intercellular communication. ⋯ For the first time, we report that plasma-derived sEV-miRNAs may act as novel circulating biomarkers and therapeutic targets in pediatric MG.
