A case-control study was conducted to examine whether occupational or environmental exposures, particularly to heavy metals, are associated with male infertility in Lebanon, a war-torn country with a history of environmental degradation. Seventy-four infertile cases and 76 fertile controls were selected from 2 major fertility clinics in Beirut. Data collection involved risk-factor interviews, semen analysis, and blood collection for heavy metal analysis. Multiple regression analysis showed that men with reported occupational exposures were twice as likely to be infertile as unexposed men. However, none of the subcategories of infertile men (based on semen analysis results) had significantly higher whole blood concentrations of heavy metals when compared to fertile controls. Blood concentrations were well within the range for referent populations of healthy individuals. Thus, despite Lebanon's poor record of occupational and environmental stewardship, exposure to metal pollutants does not appear to represent an important risk factor for male infertility.

University of Sydney, Camperdown, NSW, Australia.
Background: Dementia, including its younger-onset variant, increasingly challenges diverse workplaces, affecting both employees living with dementia and their employers. With a growing global trend of individuals extending their working years, it becomes crucial to understand the specific challenges and implications for those with dementia within various employment contexts. This review delves into the cognitive, interpersonal, and organizational challenges faced by employees living with dementia across a broad range of workplaces, reflecting the evolving dynamics of today's work environment.

University of Buenos Aires, Buenos Aires, Argentina.
Background: Increasing evidence points to the possible risk roles of psychosocial factors (lack of education, active social participation, physical exercise and mentally stimulating activity, economic instability, traumatic life events) in the pathogenic process and clinical manifestation of dementia disorders. In recent years in our country, in the context of a complex inflationary process, there has been an increase in all indicators of vulnerability and poverty, exceeding 40% of the population below the poverty line in 2023 and around 9% below the indigence line.
Method: In the context of International Alzheimer's Day, the Alzheimer's Disease Awareness Week was held at the Hospital de Clínicas of Buenos Aires.

École d'optométrie, Université de Montréal, Montréal, QC, Canada.
Background: Occupational therapists (OTs) play a crucial role in rehabilitation, aiming to improve the lives of individuals with sensory impairment and an increased risk of cognitive decline. Despite being responsible for cognitive screenings on occasion, they have expressed limited confidence in performing these with their clients with visual and/or hearing impairments (VI/HI). To improve this situation, OTs should gain expertise in collaborative sensory rehabilitation.

Occupational therapists (OTs) are among the health care professionals who assist individuals with neurocognitive disorders (NCDs) to engage in self-care and leisure activities in a skilled nursing facility (SNF) environment. OTs use various environmental modifications to help individuals with NCDs engage in various activities (Jensen & Padilla, 2017). Strong evidence has been found to support occupational therapy recommendations and interventions in adapting the physical environment to support person centered care (Gitlin et al.

Background: Limited large-scale, real-world data exist on the prevalence and clinical impact of discordance between fractional flow reserve (FFR) and nonhyperemic pressure ratios (NHPRs).
Methods: The J-PRIDE registry (Clinical Outcomes of Japanese Patients With Coronary Artery Disease Assessed by Resting Indices and Fractional Flow Reserve: A Prospective Multicenter Registry) prospectively enrolled 4304 lesions in 3200 patients from 20 Japanese centers. The lesions were classified into FFR+/NHPR-, FFR-/NHPR+, FFR+/NHPR+, or FFR-/NHPR groups according to cutoff values of 0.
