Background: Sweden has a longstanding history of promoting sexual reproductive health and rights. Reproductive decision-making is a fundamental right, but an individual's decision-making power differs across contexts. We examined self-reported reproductive agency and the acceptability of divorce, abortion and homosexuality among migrants in Sweden originating from the Middle East or North Africa (MENA) and Sub-Saharan Africa (SSA).

Background: Apolipoprotein E (APOE) genotypes have been suggested to influence cognitive impairment and clinical onset in presenilin-1 (PSEN1) E280A carriers for autosomal dominant Alzheimer's disease (ADAD). Less is known about their impact on the trajectory of biomarker changes. Neurofilament light chain (NfL), a marker of neurodegeneration, begins to accumulate in plasma about 20 years prior to the clinical onset of ADAD.

Article Synopsis
  • Triclosan, an antimicrobial additive linked to antibiotic resistance, may negatively impact the microbiome, prompting a review of existing studies on its effects.
  • The review analyzed evidence from various studies, primarily focusing on rodents, fish, and humans, indicating triclosan may reduce microbiome diversity and alter specific microbial communities, though findings were inconsistent.
  • The overall conclusion highlights a lack of adequate research on triclosan's effects on the microbiome, calling for more targeted studies and guidelines to improve future research comparability.

Autosomal dominant Alzheimer's disease (ADAD) is genetically determined, but variability in age of symptom onset suggests additional factors may influence cognitive trajectories. Although apolipoprotein E (APOE) genotype and educational attainment both influence dementia onset in sporadic AD, evidence for these effects in ADAD is limited. To investigate the effects of APOE and educational attainment on age-related cognitive trajectories in ADAD, we analyzed data from 675 Presenilin-1 E280A mutation carriers and 594 non-carriers.

Objectives: Alzheimer's disease (AD) is known to impact semantic access, which is frequently evaluated using the Category Fluency (Animals) test. Recent studies have suggested that in addition to overall category fluency scores (total number of words produced over time), poor clustering could signal AD-related cognitive difficulties. In this study, we examined the association between category fluency clustering performance (i.

Background: Sexual and reproductive health and rights (SRHR), including access and information on the laws and policies related to abortion, varies considerably between countries. Migrants may have limited knowledge of SRHR and related resources in their new country. This study investigates migrants' knowledge of the right to safe and legal abortion and other associated factors including the recent law on sexual consent, the legal age for sexual consent and age to marry in Sweden.

Background: Sexual and reproductive health and rights (SRHR) is an important aspect for young people. In Sweden, young migrants often encounter barriers to accessing and using sexual and reproductive health (SRH) services, despite that these services are free of charge for young people (ages 15-25). Healthcare providers' views and best practices are of great importance for improving the utilisation of existing SRH services, particularly for young people.

Article Synopsis
  • The study looked at how being male or female affects the risk and symptoms of Alzheimer's disease in people who carry a certain genetic mutation.
  • They analyzed data from 167 people with the mutation and 75 without it, all aged 30 to 53, using brain scans and memory tests.
  • The results showed that females had better memory than males, especially in recalling information, which suggests that women might be better at fighting off some effects of Alzheimer's compared to men.

Objective: Subjective Cognitive Decline (SCD) may be an early indicator of risk for Alzheimer's disease (AD). Findings regarding sex differences in SCD are inconsistent. Studying sex differences in SCD within cognitively unimpaired individuals with autosomal-dominant AD (ADAD), who will develop dementia, may inform sex-related SCD variations in preclinical AD.

Importance: Recent studies have suggested that unawareness, or anosognosia, of memory decline is present in predementia stages of Alzheimer disease (AD) and may serve as an early symptomatic indicator of AD.

Objective: To investigate the evolution of anosognosia of memory decline in individuals who carry the PSEN1 E280A variant for autosomal dominant AD compared with family members who do not carry the variant.

Design, Setting, And Participants: This cohort study investigated a total of 2379 members of a Colombian kindred with autosomal dominant AD who were part of the Alzheimer's Prevention Initiative Registry.

Background: Growing evidence suggests that there may be a sex-specific biological risk for Alzheimer's disease (AD). Individuals with autosomal dominant AD due to a mutation (E280A) in Presenilin-1 (PSEN1) are genetically determined to develop early-onset dementia and thus, have few age-related risk factors for AD that are known to vary by sex (i.e.

Background: The need to address sexual and reproductive health and rights (SRHR) in humanitarian settings is more urgent than ever, especially among young refugees. We conducted a scoping review to identify and synthesise the literature on perceived barriers and facilitators to SRHR among young refugees and interventions created to address their needs.

Methods: We searched three databases (PubMed, Global Health and POPLINE) for peer-reviewed and grey literature published in English between January 2008 and June 2018 that reported on SRHR barriers, facilitators and interventions for young refugees aged 10 to 24 years.

Background: Neurofilament light chain (NfL) is a promising biomarker of active axonal injury and neuronal degeneration. We aimed to characterise cross-sectional and longitudinal plasma NfL measurements and determine the age at which NfL concentrations begin to differentiate between carriers of the presenilin 1 (PSEN1) E280A (Glu280Ala) mutation and age-matched non-carriers from the Colombian autosomal dominant Alzheimer's disease kindred.

Methods: In this cross-sectional and longitudinal cohort study, members of the familial Alzheimer's disease Colombian kindred aged 8-75 years with no other neurological or health conditions were recruited from the Alzheimer's Prevention Initiative Registry at the University of Antioquia (Medellín, Colombia) between Aug 1, 1995, and Dec 15, 2018.

Neuropsychologists continue to face challenges when assessing Spanish-speaking individuals due to limited availability of normative data. We developed comprehensive normative data stratified by age and education for a Spanish neuropsychological test battery used by the Grupo de Neurociencias de Antioquia (Colombia) and the Colombian Alzheimer's Prevention Initiative Registry, which have followed large families at risk for autosomal-dominant Alzheimer's disease (ADAD) since the 1990s. Approximately 75% of these individuals are cognitively-unimpaired and are not genetically predisposed to develop ADAD.

Background: There is a need to find cognitive markers that can help identify individuals at risk for Alzheimer's disease (AD), and that can be used to reliably measure cognitive decline.

Objective: We tested whether a theoretically driven three-factor structure would characterize cognitive functioning in individuals who are genetically-determined to develop AD due to a mutation in Presenilin-1 (PSEN1) gene. We also examined whether these factors could distinguish cognitively unimpaired PSEN1 mutation carriers from age-matched non-carrier family members.
