Association of serum vitamin D level and live birth rate in women undergoing frozen embryo transfer-a retrospective cohort study.

Purpose: To assess the association of serum vitamin D level and the live birth rate in women undergoing frozen embryo transfer (FET).

Methods: This is a retrospective cohort study involving 1489 infertile women who had frozen embryo transfer at two tertiary reproductive medicine centres from 2019 to 2021. Only the first frozen embryo transfer was included for women who had repeated transfers during the period.

Public Health.

Background: Subcortical ischemic vascular cognitive impairment (SIVCI) is the most common form of vascular cognitive impairment. White matter hyperintensities (WMH) secondary to SIVCI often result in impaired executive function. Cognitive reserve is a property of the brain that allows for preserved cognitive performance given brain injury or disease.

Public Health.

Background: Subcortical ischemic vascular cognitive impairment (SIVCI) is highly prevalent in older individuals. White matter hyperintensities (WMH) are a defining feature of SIVCI. There are sex differences in SIVCI, with females having higher volume and faster WMH progression than males.

Public Health.

Background: Subcortical ischemic vascular cognitive impairment (SIVCI) is the most common form of vascular cognitive impairment. White matter hyperintensities (WMH) are hallmarks of SIVCI and are associated with impaired executive function. Cognitive reserve is a property of the brain that moderates an individual's ability to maintain cognitive performance given brain injury or pathology.

Dementia Care Research and Psychosocial Factors.

Background: Over 15 million informal caregivers provide assistance to persons living with dementia. Despite increasing emergency department (ED) use within the population, little is known regarding the support required of older adults seeking acute care with varying degrees of cognitive impairment. Our objectives were to quantify the daily care hours that informal caregivers provide to older ED patients with diagnosed dementia, undiagnosed cognitive impairment, and intact cognition.
