Respiratory syncytial virus (RSV) causes a substantial health burden among infants and older adults. Prefusion F protein-based vaccines have shown high efficacy against RSV disease in clinical trials, offering promise for mitigating this burden through maternal and older adult immunization. Employing an individual-based model, we evaluated the impact of RSV vaccination on hospitalizations and deaths in 13 high-income countries, assuming that the vaccine does not prevent infection or transmission.

Understanding the current state of equity, diversity, and inclusion (EDI) within the crisis line sector is essential to enhancing accessibility and acceptability of crisis line services for all. Through an intersectional lens, we examined 9-8-8 crisis line workers' personal and work demographics, training, resources, perceived competencies in supporting diverse populations. We conducted an electronic survey of crisis line responders and leadership in Canada.

Continuously emerging SARS-CoV-2 Omicron subvariants pose a threat thwarting the effectiveness of approved COVID-19 vaccines. Especially, the protection breadth and degree of these vaccines against antigenically distant Omicron subvariants is unclear. Here, we report the immunogenicity and efficacy of a bivalent mRNA vaccine, PTX-COVID19-M1.

Cardiovascular diseases account for ~40% of global deaths annually. This situation has revealed the urgent need for the investigation and development of corresponding drugs for pathogenesis due to the complexity of research methods and detection techniques. An in vitro cardiomyocyte model is commonly used for cardiac drug screening and disease modeling since it can respond to microphysiological environmental variations through mechanoelectric feedback.

With advances in conditioning strategies and graft-versus-host disease (GvHD) prevention, hematopoietic stem cell transplantation (HSCT) is a safe, curative treatment option for pediatric patients with sickle cell disease (SCD). However, donor options have been limited in non-myeloablative matched sibling donor (MSD) setting by excluding recipients with major ABO blood group incompatible donors due to concern of the risk of significant complications such as pure red cell aplasia (PRCA). We present three cases of successful HSCT with major ABO incompatibility with their donors, and discuss strategies to safely expand the donor pool to include these donors.

Introduction: Cardiovascular diseases (CVDs) present differently in women and men, influenced by host-microbiome interactions. The roles of sex hormones in CVD outcomes and gut microbiome in modifying these effects are poorly understood. The XCVD study examines gut microbiome mediation of sex hormone effects on CVD risk markers by observing transgender participants undergoing gender-affirming hormone therapy (GAHT), with findings expected to extrapolate to cisgender populations.

Medical treatment for LTC residents, when not aligned with residents' wishes, can cause discomfort without providing substantial benefits. Predictive models can equip providers with tools to guide treatment recommendations that support person-centred medical decision-making.

The precuneus is a site of early amyloid-beta (Aβ) accumulation. Previous cross-sectional studies reported increased precuneus fMRI activity in older adults with mild cognitive deficits or elevated Aβ. However, longitudinal studies in early Alzheimer's disease (AD) are lacking and the relationship to the Apolipoprotein-E () genotype is unclear.

While decreasing negative attitudes against outgroups are often reported by individuals themselves, biased behaviour prevails. This gap between words and actions may stem from unobtrusive mental processes that could be uncovered by using neuroimaging in addition to self-reports. In this study we investigated whether adding neuroimaging to a traditional intergroup bias measure could detect intersubject differences in intergroup bias processes in a societal context where opposing discrimination is normative.

The blood-brain barrier (BBB) plays a vital role in protecting the central nervous system (CNS) by preventing the entry of harmful pathogens from the bloodstream. However, this barrier also presents a significant obstacle when it comes to delivering drugs for the treatment of neurodegenerative diseases and brain cancer. Recent breakthroughs in nanotechnology have paved the way for the creation of a wide range of nanoparticles (NPs) that can serve as carriers for diagnosis and therapy.

Background: The impact of direct and indirect drivers on linear growth and wasting in young children is of public health interest. While the contributions of poverty, maternal education, empowerment and birth weight to early childhood growth are well recognized, the contribution of environmental factors like heat, precipitation, agriculture outputs and food security in comparable datasets is less well established.
Objectives: To investigate the association of length-for-age z-score (LAZ) and weight-for-length z-score (WLZ) with various indicators among children under 2 years of age in Pakistan using representative household level nutrition surveys and ecological datasets.

Background: Infliximab and adalimumab are the only biologics thus far approved for paediatric patients with inflammatory bowel disease (IBD), so other biologics, such as vedolizumab, are prescribed off-label. Despite its frequent use, prospective data for vedolizumab treatment in children are available only for short-term induction outcomes. We aimed to evaluate the long-term efficacy and safety of maintenance therapy with vedolizumab in paediatric patients with IBD.

The cognitive neuroscience of human aging seeks to identify neural mechanisms behind the commonalities and individual differences in age-related behavioral changes. This goal has been pursued predominantly through structural or "task-free" resting-state functional neuroimaging. The former has elucidated the material foundations of behavioral decline, and the latter has provided key insight into how functional brain networks change with age.

Background And Objective: It is unclear whether variation in covert cerebrovascular disease prevalence is attributable to ethnic differences or to other factors. We aimed to examine the associations of country of residence with covert vascular brain injury (VBI) and cognitive dysfunction among Chinese adults residing in Canada and China.

Background: Children born to women with inflammatory bowel disease (IBD) may have increased healthcare utilization in early life due to genetic susceptibilities and exposure to inflammation in utero, though this has not been robustly evaluated. We aimed to characterize healthcare use between these groups.
Methods: We accessed province-wide health administrative databases to identify children born to women with and without IBD between 2002-2019.
