As a result of caring for a person with dementia, caregivers of persons with Alzheimer's disease (AD) may be uniquely aware of public stigma for persons with AD.

The purpose of this study was to compare self-identified caregivers and non-caregivers' expectations of public stigma experienced by persons living with dementia.

Analysis of data from a survey of 910 adults (median age = 49 years) who read a vignette about a man with mild stage dementia. Multivariable ordered logistic regression was used to examine how AD caregiver status associated with responses on a modified Family Stigma in Alzheimer's Disease Scale (FS-ADS).

9%(
 = 82) of respondents self-identified as a current or former primary caregiver of a person with AD, about the same as the national estimate of informal caregivers (8.8%). Compared to non-caregivers, AD caregivers were more likely to report stronger reactions on all seven domains of the FS-ADS (all
 <  0.05). As compared to AD caregivers with less factual knowledge about caregiving, AD caregivers with more knowledge expected the person with dementia to experience less
(
 <  0.05). In addition, female AD caregivers reported fewer
than male AD caregivers (
 <  0.05).

Compared to non-caregivers, respondents who self-identified as an AD caregiver gave responses that suggest they perceived more stigma of dementia among members of the public. Their reactions were attenuated by AD knowledge and being female. The findings have key implications for interventions to reduce AD stigma.

The present systematic review and meta-analysis of diagnostic test accuracy summarizes the last three decades in advances on diagnosis of Alzheimer's disease (AD) in developed and developing countries.

To determine the accuracy of biomarkers in diagnostic tools in AD, for example, cerebrospinal fluid, positron emission tomography (PET), and magnetic resonance imaging (MRI), etc.

The authors searched PubMed for published studies from 1990 to April 2020 on AD diagnostic biomarkers. 84 published studies were pooled and analyzed in this meta-analysis and diagnostic accuracy was compared by summary receiver operating characteristic statistics.

Overall, 84 studies met the criteria and were included in a meta-analysis. For EEG, the sensitivity ranged from 67 to 98%, with a median of 80%, 95% CI [75, 91], tau-PET diagnosis sensitivity ranged from 76 to 97%, with a median of 94%, 95% CI [76, 97]; and MRI sensitivity ranged from 41 to 99%, with a median of 84%, 95% CI [81, 87]. Our results showed that tau-PET derica.
Alzheimer's disease (AD) is characterized by the aggregation of two pathological proteins, amyloid-β (Aβ) and tau, leading to neuronal and cognitive dysfunction. Clearance of either Aβ or tau aggregates by immunotherapy has become a potential therapy, as these aggregates are found in the brain ahead of the symptom onset. Given that Aβ and tau independently and cooperatively play critical roles in AD development, AD treatments might require therapeutic approaches to eliminate both aggregates together.

We aimed to discover a chemical drug candidate from natural sources for direct dissociation of both insoluble Aβ and tau aggregates through
assessments.

We isolated four borrelidin chemicals from a saltern-derived halophilic actinomycete strain of rare genus
and simulated their docking interactions with Aβ fibrils. Then, anti-cytotoxic, anti-Aβ, and anti-tau effects of borrelidins were examined by MTT assays with HT22 hippocampal cell line, thioflavin T assays, and gel electrophoresis.

When HT22 cells were exposed to Aβ aggregates, the treatment of borrelidins alleviates the Aβ-induced toxicity. These anti-cytotoxic effects can be derived from the inhibitory functions of borrelidins against the Aβ aggregation as shown in thioflavin T and gel electrophoretic analyses. Among them, especially borrelidin, which exhibits the highest probability of docking, not only dissociates Aβ aggregates but also directly regulates tau aggregation.

Borrelidin dissociates insoluble Aβ and tau aggregates together and our findings support the view that it is possible to develop an alternative chemical approach mimicking anti-Aβ or anti-tau immunotherapy for clearance of both aggregates.

It is inconclusive on how sex affects the risk of developing mild cognitive impairment (MCI) or dementia.

To investigate how sex affects the risk of developing MCI or dementia.

A secondary data analysis was performed on data collected from participants enrolled at Alzheimer's Disease Research Centers funded by National Institute on Aging. There were two inclusion criteria 1) participants were free of dementia at the baseline visit; 2) every participant must have at least one follow-up visit. A Cox proportional hazards model was used to investigate how sex affects the risk of developing cognitive impairments.

During a follow-up period of more than 10 years, male participants had a slightly higher incidence than female participants for either MCI or dementia. DNA Repair inhibitor Not surprisingly, a higher prevalence was observed in male than female participants for either MCI or dementia. However, male participants had a higher mortality rate than their female counterparts.

The male sex is associated with a higher risk for developing cognitive impairments along the aging process.

Uncertainty of the COVID-19 status among the donated bodies poses a health risk for embalming personnel and medical students who handle the embalmed cadavers. There is a paucity of literature delineating the criteria for accepting or rejecting the bodies during COVID-19 pandemic. Similarly, there is no recommended standard operating procedure for anatomical embalming during COVID-19. We propose certain criteria for accepting and rejecting the human dead bodies for anatomical embalming. And we propose some technical modifications to the conventional procedure of formalin-based anatomical embalming. A guarded approach and diligent screening of donated bodies is the way forward during the COVID-19 pandemic.
