Adding‐On Wisely: Hematopathology Reflective Testing in Canada

INTRODUCTION: Reflective testing describes laboratory clinicians' discretionary addition of testing on existing samples, after initial result review. This practice has proven valuable in clinical biochemistry but faces controversy regarding consent and costs. No prior research ex...

Eye Findings Following Congenital Cytomegalovirus Newborn Screening

BACKGROUND AND OBJECTIVE: Consensus guidelines have recommended eye examinations for all newborns with congenital cytomegalovirus (cCMV) infection; however, structured ophthalmic examinations are seldom reported. Existing literature suggests ocular pathology is uncommon in cCMV,...

The frequency of spawning and skipped migration in a central Canadian population of anadromous Arctic char inferred using acoustic telemetry

Understanding spawning frequency and migration behaviour is essential for managing iteroparous anadromous fishes such as Arctic char (Salvelinus alpinus). Using a decade of acoustic telemetry data from southern Victoria Island, Nunavut, we examined the frequency of marine migrati...

Critical antecedents for successful labor-management partnerships (LMP): taxonomy, levels and the “black boxes”

Purpose Employment relations studies have examined the notion and practice of labor-management partnership (LMP); yet, a delineation of overarching explanations for successful LMP remain outstanding. This study sought to identify and classify critical antecedents for successful L...

Validity of the center for epidemiological studies depression (CES-D) scale for depression screening in postpartum adolescents in Uganda

In Uganda, 25% of pregnancies occur among teenagers and an estimated 20.7% have postpartum depression. Postpartum depression is often underdiagnosed due to insufficient mental health resources and few validated screening tools for adolescent mothers. Addressing this gap, psychome...

Unwanted dead or alive? Gender, citizenship, and the afterlife of security in media representations of deceased ISIS members

Abstract This article undertakes a gendered analysis of media representations of deceased ISIS-affiliated citizens in Australia, the United Kingdom, and France to examine how death functions differently for men and women within contemporary counterterrorism governance. It argues...

The Role of Transparency in Repeated First-Price Auctions with Unknown Valuations

Abstract. We study the problem of regret minimization for a single bidder in a sequence of first-price auctions where the bidder discovers the item’s value only if the auction is won. Our main contribution is a complete characterization, up to logarithmic factors, of the minimax...

Development and internal validation of an EHR machine learning model for clinical deterioration in ICU linked inpatients

Abstract Early warning scores for inpatient deterioration rely predominantly on contemporaneous vital signs and may not incorporate broader electronic health record (EHR) information. We developed and internally validated a multi-domain EHR machine-learning model using MIMIC-IV v...

General heat release rate surrogates for NH3/H2/N2 and H2 flames using Raman/Rayleigh/LIF accessible species

Accurate estimation of the heat-release rate (HRR) is essential for understanding and controlling ammonia–hydrogen combustion, yet conventional experimental surrogates are strongly dependent on operating conditions and typically rely on radicals measured by laser-induced fluoresc...

Assessing sport coaches’ gender beliefs: Development and preliminary validation of the girls-centred coaching self-efficacy scale (GCSES)

Coaches play a critical role in shaping girls’ sport experiences; however, limited empirical attention has been paid to coaches’ confidence in recognizing the influence of gender beliefs within their practice. Despite growing calls for gender-responsive and gender transformative...

Postprandial Triglyceride Excursions and the Potential Effect of Menstrual Cycle Phases: A Narrative Review of Human Physiology with Clinician and Patient Perspectives

Postprandial lipemia, the transient rise in circulating triglyceride-rich lipoproteins after consuming a meal, plays a significant role in cardiometabolic disease risk beyond the contribution of fasting lipid concentrations. While pharmaceutical therapies have been highly effecti...

Laurentian French vowel laxing: an articulatory and acoustic study

Abstract In Laurentian French (LF), the high vowels /i y u/ are realized as lax [ɪ ʏ ʊ] in syllables closed by certain consonants. Previous work on vowel laxing has focused primarily on describing the environments in which it occurs and on providing an acoustic characterization o...

Lobar Brain Volume Associations With Brain-Age Gap in Canadian Special Operations Forces Breachers

OBJECTIVE: To determine whether military breachers show significant positive raw brain-age gap and to identify which intracranial-volume (ICV)-normalized lobar volumes best predict bias-corrected brain-age gap (BAGc). SETTING AND PARTICIPANTS: Eighty-five male (mean age 30.1 ± 4....

The efficacy and safety of celecoxib for postoperative pain in major orthopedic surgery: a systematic review and pairwise meta-analysis

Effective postoperative pain management is crucial for surgical recovery, yet opioid-based therapies carry significant risks of addiction and adverse effects. Celecoxib, a selective COX-2 inhibitor, has emerged as a promising non-opioid alternative within multimodal analgesic pro...

Sex & Gender Science: integrating the social with the biological

Abstract For decades, researchers have largely studied aspects of sex and gender separately; the former as a basic science and the latter as a social construct with real world consequences, including health inequities. In recent years, as our collective understanding of how the b...

Investigating acute-to-subacute neuroanatomical outcomes and the role of sex and age in adolescent concussion: A PedCARE+MRI substudy

Background Limited research has examined acute-to-subacute neuroanatomical trajectories following adolescent concussion. To investigate acute-to-subacute longitudinal changes in cortical thickness and subcortical volume following adolescent concussion, we compared neuroanatomical...

Understanding disparities in autism diagnosis and care: A socioecological perspective

Disparities in autism spectrum disorder (ASD) identification and care are well documented across racial and ethnic, socioeconomic, and geographic lines, yet their underlying mechanisms are incompletely understood. This paper applies the Socioecological Model (SEM) as an organizin...

Leveraging prompt-driven generative AI for systematic reviews in digital psychiatry: A stage-matched comparative proof-of-concept for healthcare researchers and clinicians

The scale and pace of evidence generation in digital psychiatry increasingly exceed the capacity of traditional systematic literature review (SLR) methods. Large language models (LLMs) are gaining traction in evidence synthesis, yet limited guidance exists for integrating generat...

Effectiveness of Selective Cyclooxygenase-2 Inhibitors for Postoperative Pain Management Using Multidimensional Pain Assessment: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

BACKGROUND: Although selective cyclooxygenase-2 (COX‑2) inhibitors are commonly used in perioperative pain management, it is uncertain whether these anti-inflammatory agents meaningfully improve postoperative recovery, including the impact of pain on daily functioning. METHODS: T...

Association of Moringa stenopetala based dietary consumption with thyroid function among adults in southern Ethiopia: a multicenter comparative cross-sectional study

Thyroid hormones, including triiodothyronine (T3) and thyroxine (T4), are synthesized by the thyroid gland and play essential roles in regulating metabolism, growth, and neurodevelopment. Prolonged consumption Moringa stenopetala based diet has been suggested as a potential risk...
