Ethnic and racialized disparities in the use of screening services for pap smears and mammograms in Canada.

Background: Breast and cervical cancers pose significant health challenges for women globally, emphasizing the critical importance of effective screening programs for early detection. In Canada, despite the implementation of accessible healthcare systems, ethnic and racialized disparities in cancer screening persist. This study aims to assess ethnic and racialized disparities in breast and cervical cancer screening in Canada.

Public Health Interventions Targeting the Prevention of Adolescent Vaping: A Scoping Review.

Objective: Despite a brief decline during the COVID-19 pandemic, vaping behaviors among adolescents continue to be an international public health concern because of associated health risks and harms. A thorough investigation of existing interventions preventing adolescent vaping is needed to help address this public health crisis and reduce serious and avoidable vaping-related health risks. We reviewed the literature to identify public health interventions aimed at preventing adolescent vaping and summarized their key components and outcome measures.

An assessment of cancer centre level designation and guideline adherent care in those with rectal cancer: A population based retrospective cohort study.

Background: Institutions providing care to individuals with cancer are organized based on available resources and treatments offered. It is presumed that increasing levels of care will result in improved quality of care and outcomes. The objective is to determine whether Cancer Level Designation is associated with guideline adherent care and/or survival.

Network-based modelling reveals cell-type enriched patterns of non-coding RNA regulation during human skeletal muscle remodelling.

A majority of human genes produce non-protein-coding RNA (ncRNA), and some have roles in development and disease. Neither ncRNA nor human skeletal muscle is ideally studied using short-read sequencing, so we used a customised RNA pipeline and network modelling to study cell-type specific ncRNA responses during muscle growth at scale. We completed five human resistance-training studies (n=144 subjects), identifying 61% who successfully accrued muscle-mass.

Institutional trust, conspiracy beliefs and Covid-19 vaccine uptake and hesitancy among adults in Ghana.

Vaccine hesitancy is considered one of the ten threats to global health. In the context of the COVID-19 pandemic, vaccine hesitancy may undermine efforts toward controlling or preventing the disease. Nevertheless, limited research has examined vaccine hesitance, particularly in low- and middle-income countries (LMICs).

Probabilistic bias analysis for exposure misclassification of household income by neighbourhood in a cohort of individuals with colorectal cancer.

Introduction: Despite poor agreement, neighbourhood income is used as a proxy for household income, due to a lack of data availability. We quantified misclassification between household and neighbourhood income and demonstrate quantitative bias analysis (QBA) in scenarios where only neighbourhood income is available in assessing income inequalities on colorectal cancer mortality.

Methods: This was a retrospective study of adults with colorectal cancer diagnosed 2006-14 from Statistics Canada's Canadian Census Health and Environment Cohort.

The Effect of Screen Time and Positive School Factors in the Pathway to Child and Youth Mental Health Outcomes.

Beyond achievement, educational settings offer informal supports that may be critical for child and youth mental health. However, children's educational environments have experienced significant disruption with the coronavirus pandemic. School settings offer unique opportunities to support children's mental health, but research must identify powerful points of intervention.

A 10-year (2014-2023) review of complementary food development in sub-Saharan Africa and the impact on child health.

Complementary foods (CFs) commonly consumed by infants and young children (IYC) in sub-Saharan Africa (SSA) are processed using either single or multi-grain ingredients through simple technologies such as fermentation, malting and roasting. Interestingly, CFs (e.g.

Hand Eczema. Part 2: Prevention, management, and treatment.

Prevention methods are important for patients with hand eczema (HE), especially those with risk factors. Frequent use of moisturizers is encouraged. Few drugs have been approved specifically for HE.

Pathways to cancer care after a suspected cancer diagnosis in the emergency department: a survey of emergency physicians across Ontario.

Introduction: Little is known about how patients are managed after a suspected cancer diagnosis through the emergency department. The objective of this study was to examine the ED management, specifically referral practices, for ten suspected cancer diagnoses by emergency physicians across Ontario and to explore variability in management by cancer-type and centre.

Methods: An electronic survey was distributed to emergency physicians across Ontario, asking about referral practices for patients who could be discharged from the ED with one of ten suspected cancer diagnoses.

Negotiating familial mental illness stigma: The role of family members of persons living with mental illnesses.

Background: This study explores how family members of individuals with mental illnesses address potential familial mental illness stigma. Previous studies have concentrated on self, social, and associative stigma and its impacts on families and persons with mental illnesses. Far less work has considered family members as perpetrators of mental illness stigma towards their loved ones with mental illnesses.

BNT162b2 Versus mRNA-1273 Vaccines: Comparative Analysis of Long-Term Protection Against SARS-CoV-2 Infection and Severe COVID-19 in Qatar.

Background: This study provides a head-to-head comparison of the protection provided by the BNT162b2 and mRNA-1273 vaccines against SARS-CoV-2 infection and against severe COVID-19, covering primary series and third dose/booster vaccinations over up to 3 years of follow-up, both before and after the emergence of the omicron variant.

Methods: Two national, matched, retrospective cohort studies were conducted on Qatar's vaccinated population from December 16, 2020, to February 18, 2024. Subgroup analyses by pre-vaccination SARS-CoV-2 infection history, as well as sensitivity analyses, were also conducted.

A living critical interpretive synthesis to yield a framework on the production and dissemination of living evidence syntheses for decision-making.

Background: The COVID-19 pandemic has had an unprecedented impact in the global research production and has also increased research waste. Living evidence syntheses (LESs) seek to regularly update a body of evidence addressing a specific question. During the COVID-19 pandemic, the production and dissemination of LESs emerged as a cornerstone of the evidence infrastructure.

A Multi Comparison of 8 Different Intraocular Lens Biometry Formulae, Including a Machine Learning Thin Lens Formula (MM) and an Inbuilt Anterior Segment Optical Coherence Tomography Ray Tracing Formula.

A comparison of the accuracy of intraocular lens (IOL) power calculation formulae, including SRK/T, HofferQ, Holladay 1, Haigis, MM, Barrett Universal II (BUII), Emmetropia Verifying Optical (EVO), and AS-OCT ray tracing, was performed. One hundred eyes implanted with either the Rayone EMV RAO200E (Rayner Intraocular Lenses Limited, Worthing, UK) or the Artis Symbiose (Cristalens Industrie, Lannion, France) IOL were included. Biometry was obtained using IOLMaster 700 (Carl Zeiss Meditec AG, Jena, Germany) and MS-39 AS-OCT (CSO, Firenze, Italy).
