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: Hematological cancers have devastating effects on patients' physical, emotional, and psychosocial health. There is growing evidence to support the use of patient-reported outcome measures (PROMs) through validated tools. Although PROMs are widely adopted in oncology, uptake in hematology remains limited in routine clinical care.

Background: Mpox was identified in many previously non-endemic countries, including Canada, as of May 2022. In response to the increase in cases in Canada, and more specifically the province of Ontario, the vaccine Imvamune was rolled out. Eligibility was governed by provincial health authorities, and the response varied by region.

Introduction: Exposure of healthcare workers to hazardous drugs may result in adverse health effects underscoring the importance of validating working procedures and safety precautions to minimise the risk. The objective was to monitor environmental contamination caused by the hazardous drug workflow: from drug vials, compounding process, to patient administration.

Methods: Surface wipe samples were collected from potentially contaminated surfaces in the compounding department and in the administration department.

Objective: To co-design support strategies to enable sustainable, healthy, affordable food provision, including waste mitigation practices, in Australian Early Childhood Education and Care (ECEC) settings.

Design: Based upon the co-design IDEAS framework (Ideate, DEsign, Assess & Share), this co-design process involved iterative interviews and focus groups with ECEC centre staff, and workshops with Nutrition Australia. Interview and workshop themes were coded to the Theoretical Domains Framework (TDF) to develop initial prototypes for support strategies that were further developed and refined in focus groups.

Purpose: Despite the important role of dietary fat in early childhood, our understanding of fat intake trends during this period is limited, particularly among Australian children. This study aimed to describe total and saturated fat (SFA) intake trends, food sources, and tracking in young Australian children.

Methods: Data of children at ages 9 months (n = 393), 18 months (n = 284), 3.

Article Synopsis
  • Unfavorable beliefs regarding oral health during pregnancy can lead to avoidance of dental care, negatively impacting both maternal and fetal health.
  • A survey targeting pregnant women in Southwestern Ontario found that many participants held misconceptions about the effects of oral health on their child's health and the impact of dental treatment during pregnancy.
  • The study concluded that there is a pressing need for better education and communication around oral health to address these concerns and improve dental care utilization among pregnant women.

Associative memory declines with age, and this decline is thought to stem from a decreased ability to form new associations or bind information together. However, a growing body of work suggests that (a) the binding process itself remains relatively intact with age when tested implicitly and (b) older adults form excessive associations (or "hyper-bind") because of a decreased ability to control attention. In this article, we review evidence for the hyper-binding hypothesis.

Background: Planning for place of death is considered troublesome for patients with hematological cancer. Qualitative studies have focused on healthcare professionals and caregivers. To date, no study has been conducted from the patient's perspective of planning for place of death in the last year of life.

Background: Stigma is a complex social phenomenon that leads to marginalization and influences the course of illness. In the context of hepatitis C virus (HCV), stigma is a well-documented barrier to accessing care, treatment, and cure. In recent years, HCV rates among women have increased, resulting in an urgent need to address stigma and its harmful effects.

Article Synopsis
  • - Obesity rates rise with age and can even be seen in early childhood, which is a crucial stage that influences long-term health outcomes.
  • - Research on childhood obesity has gained attention in the last two decades, but there is still a lack of comprehensive studies that advance understanding in this area.
  • - Obesity is influenced by various factors, including biological, sociocultural, and environmental aspects, necessitating collaborative and multifaceted interventions to effectively address the issue from conception onward.

Article Synopsis
  • Oral health during pregnancy is crucial for both mother and fetal well-being, yet access to dental care for pregnant women in Canada shows significant disparities and gaps in research.
  • A study in southwestern Ontario surveyed 130 pregnant women about their oral health and dental care, revealing that while most perceived their oral health positively, only a small percentage visited a dentist during pregnancy.
  • Key findings indicated that education level and quality of life influenced oral health perceptions, underscoring the necessity for improved dental care access and integration for pregnant women.

Mind wandering is typically characterized as a failure of attentional control, yet despite age-related executive function deficits, older adults typically report less mind wandering than younger adults during cognitive tasks and in daily life. Self-reported mind wandering episodes usually result in similar behavioral detriments in younger and older adults (e.g.

Introduction: Multiple sclerosis (MS) is an immune-mediated demyelinating disease with a significant burden of neuropsychiatric sequelae. These symptoms, including depression and anxiety, are predictors of morbidity and mortality in people with MS. Despite a high prevalence of obsessive-compulsive disorder in MS, potentially shared pathophysiological mechanisms and overlap in possible treatments, no review has specifically examined the clinical dimensions of people with obsessive-compulsive and related disorders (OCRD) and MS.

While cognitive aging research has compared episodic memory accuracy between younger and older adults, less work has described differences in how memories are encoded and recalled. This is important for memories of real-world experiences, since there is immense variability in which details can be accessed and organized into narratives. We investigated age effects on the organization and content of memory for complex events.

Mobile health (mHealth) interventions provide a low-cost, scalable approach to supporting parents with infant feeding advice with the potential to reduce health care visits and associated costs for infant feeding support. This Australian study examined the impact of the Growing healthy (GH) app on health service utilisation and out-of-pocket costs for families in the first 9 months of their infants life. A quasi-experimental study with a comparison group was conducted in 2015-2016 with an mHealth intervention group (GH app, n = 301) and a nonrandomized usual care group (n = 344).

Importance: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Observational studies report that β-blocker use may be associated with reduced risk of COPD exacerbations. However, a recent trial reported that metoprolol did not reduce COPD exacerbations and increased COPD exacerbations requiring hospital admission.

While previous work has shown a positive relationship between cognitive performance and lifestyle factors in younger adults, evidence for this relationship among middle-aged and older adults has been mixed. The current study aimed to further test the relationship among physical activity, sleep quality, and memory performance in middle-aged and older adults, and to test whether this relationship holds up during the COVID-19 pandemic. Our results showed that physical activity was associated with better sleep quality and better working memory performance, and better sleep quality was associated with better working memory and self-perceptions of everyday memory abilities.
