Knowledge, Awareness, and Attitude of Healthcare Stakeholders on Alzheimer's Disease and Dementia in Qatar

Attitudes Towards Dementia Among a Diverse Group of Refugees Resettled in the United States

BACKGROUND

Forced migration results in exposure to trauma, interrupted access to healthcare, and loss of social support and may increase dementia risk. Literature on refugees' knowledge of dementia and its risk factors is scant. This study investigates refugee perspectives on dementia and their access to cognitive healthcare in the United States (US).

METHODS

We conducted 6 focus groups and 30 individual in-depth interviews (total of 69 participants) with Arab, African, and Afghan refugees resettled in San Diego, California. Data was coded using inductive thematic analysis.

RESULTS

Organized by the socioecological model of health, the following themes emerged: (1) mental trauma due to migration was linked to dementia (individual); (2) fear of dementia and burdening caregivers due to limited support systems (interpersonal); (3) reliance on virtual communities for dementia information and the stress of local community loss increasing dementia risk (community); (4) healthcare providers, both in the US and in refugee camps, didn't address cognitive health concerns (institutions); and (5) discriminatory immigration and healthcare policies as barriers to healthy aging (policy).

DISCUSSION

Despite being a heterogeneous group, refugees share specific experiences, knowledge gaps, and barriers to healthy aging. Tailored interventions and policies are needed to address this population's cognitive health needs. This includes addressing their mental health and social support concerns as well as training clinicians to screen for/discuss dementia with aging refugee patients.

Heterocyclic compounds, especially those containing the pyrazole moiety, are highly significant in organic chemistry and possess remarkable and diverse biological properties. The 5-aminopyrazole derivatives are key starting materials for the synthesis of numerous bioactive compounds such as pyrazolopyridine, pyrazolopyrimidine, pyrazoloquinazoline, and pyrazolotriazine derivatives. Many compounds inspired by the 5-aminopyrazole derivatives possess a wide spectrum of biological activities and medicinal applications such as antioxidants, anticancer agents, enzyme inhibitors, antimicrobials, and anti-tuberculosis activities. This review summarizes the recently reported synthesis methods and biological activities of fused pyrazole and pyrazole-based derivatives based on 5-aminopyrazole compounds within the last 5 years (2020 to present). One of the important goals of this review is to illustrate future strategies for the design, development, and utilization of pyrazole products as potent drugs.

Exploring Healthcare Providers' Difficulties and Strategies when Caring for Community-Dwelling People With Dementia Who are at Risk of Getting Lost

Caring for patients with dementia at risk of getting lost is challenging for community healthcare providers. Through semi-structured interviews with 25 participants, we examined the challenges faced by these providers and the strategies they employed. We identified the following themes of challenging parts: (a) the disturbance caused by behavioral and psychological symptoms in dementia; (b) difficulty in helping older family caregivers to keep the patient from going out; (c) difficulty in changing the attitudes of the family members; families' unawareness of the risk of getting lost. We also identified the following strategies to mitigate these themes: (a) detecting the risk of getting lost through early assessment; (b) encouraging the family to use resources or devices to prevent the patient from getting lost; (c) educating the family to manage behavior and psychological symptoms of dementia; (d) strengthening the patient's crisis awareness.

A systematic review on factors influencing Middle Eastern women's utilization of healthcare services: The promise of mHealth

Objectives

The 2030 Sustainable Development Agenda stresses a feminist approach for healthcare services. Cultural and religious influences impact utilization of healthcare services by Muslim women within the Middle East, posing unique challenges. This paper aimed to investigate the factors influencing Middle Eastern women's utilization of healthcare services within the region.

Methods

In the year 2024, a systematic review was conducted. PubMed, Scopus, ProQuest, and the Cochrane Database of Systematic Reviews were searched for this purpose. The quality of the included articles was assessed using the Accuracy, Coverage, Objectivity, Date, Significance (ACODS) checklist. Subsequently, the Joffe method of thematic analysis was employed to analyze the data obtained from the review.

Results

A final selection comprising 59 studies was made for inclusion in the research. The studies demonstrated a high level of quality, and the risk of bias within them was deemed acceptable. The thematic analysis revealed seven principal themes, which encompassed Demographic Factors, Level of Education and Awareness, Sources of Information, Risk Factors, Personal Factors, Level of Service Access and Quality, and Organizational Factors.

Conclusions

This study highlighted key factors influencing women's utilization of healthcare in the Middle East and potentially the healthcare systems with a large number of Middle Eastern female immigrants around the globe: educational factors such as awareness campaigns and patient education, and personal barriers like fear and cultural norms. Moreover, Telehealth, particularly mHealth, was suggested to enhance women's participation and utilization of healthcare services. Further research is needed to explore this assertion with greater precision.

Knowledge, attitudes, and practices regarding perioperative neurocognitive disorders among anesthesia practitioners

Objectives

This study aimed to investigate the knowledge, attitudes, and practices (KAP) among anesthesia practitioners concerning perioperative neurocognitive disorders (PND).

Methods

This cross-sectional study enrolled anesthesia practitioners from 18 hospitals in China using s self-administered questionnaire between July and September 2023.

Results

A total of 200 (98.04 %) valid questionnaire were enrolled, the responders of which aged 36.56 ± 8.24 years, including 130 (65 %) females. The mean KAP scores were 12.28 ± 3.78 (possible range: 0 20),29.22 ± 3.28 (possible range: 8-40), and 29.32 ± 4.30 (possible range: 8-40), respectively. The path analysis demonstrated that number of daily surgical cases (β = 0.82, p = 0.018), education (β = 1.49, p < 0.001), and participation in a related research project (β = 1.32, p = 0.003) had direct effects on knowledge. Working in teaching hospital has direct effect on attitude (β = 1.82, p = 0.027). Furthermore, knowledge (β = 0.29, p < 0.001) and attitude (β = 0.20, p = 0.026) also have direct effects on practice.

Conclusions

Anesthesia practitioners had inadequate knowledge, positive attitude, and proactive practice towards PND. Number of daily surgical cases, education, participation in a related research project, and working in teaching hospital might have effects on their KAP.

Experimental and computational investigation of the effect of Hsc70 structural variants on inhibiting amylin aggregation

The misfolding and aggregation of human islet amyloid polypeptide (hIAPP), also known as amylin, have been implicated in the pathogenesis of type 2 diabetes (T2D). Heat shock proteins, specifically, heat shock cognate 70 (Hsc70), are molecular chaperones that protect against hIAPP misfolding and inhibits its aggregation. Nevertheless, there is an incomplete understanding of the mechanistic interactions between Hsc70 domains and hIAPP, thus limiting their potential therapeutic role in diabetes. This study investigates the inhibitory capacities of different Hsc70 variants, aiming to identify the structural determinants that strike a balance between efficacy and cytotoxicity. Our experimental findings demonstrate that the ATPase activity of Hsc70 is not a pivotal factor for inhibiting hIAPP misfolding. We underscore the significance of the C-terminal substrate-binding domain of Hsc70 in inhibiting hIAPP aggregation, emphasizing that the removal of the lid subdomain diminishes the inhibitory effect of Hsc70. Additionally, we employed atomistic discrete molecular dynamics simulations to gain deeper insights into the interaction between Hsc70 variants and hIAPP. Integrating both experimental and computational findings, we propose a mechanism by which Hsc70's interaction with hIAPP monomers disrupts protein-protein connections, primarily by shielding the β-sheet edges of the Hsc70-β-sandwich. The distinctive conformational dynamics of the alpha helices of Hsc70 potentially enhance hIAPP binding by obstructing the exposed edges of the β-sandwich, particularly at the β5-β8 region along the alpha helix interface. This, in turn, inhibits fibril growth, and similar results were observed following hIAPP dimerization. Overall, this study elucidates the structural intricacies of Hsc70 crucial for impeding hIAPP aggregation, improving our understanding of the potential anti-aggregative properties of molecular chaperones in diabetes treatment.

Evaluation of knowledge and attitudes regarding Alzheimer's disease and related dementia among medical students in Palestine: A cross-sectional study

INTRODUCTION

Dementia, a major global health concern, is an acquired disorder that causes a progressive decline in cognitive abilities, affecting learning and memory, language, executive function, complex attention, perceptual-motor skills, and social cognition. Our study aims to evaluate the knowledge and attitudes regarding dementia and Alzheimer's disease among medical students.

METHODS

This cross-sectional study was conducted among 393 medical students in Palestine from August 2023 to November 2023. The assessment of knowledge and attitude toward dementia was measured using the Alzheimer's Disease Knowledge Scale (ADKS) and Dementia Attitude Scale (DAS). The data were analyzed using SPSS version 26, and the Mann-Whitney U-test and the Kruskal-Wallis test were used to compare the mean between the groups with a 5% significance level.

RESULTS

The overall mean score of the student's knowledge of dementia measured by the ADKS was 18.91 (±3.32 SD) out of 30. The mean score of the student's attitude toward dementia measured by the DAS was 91.68 (±3.32 SD). Clinical students had higher ADKS scores than pre-clinical students (p-value < 0.001). No significant differences in the knowledge and attitudes toward dementia were found between males and females. The medical students' knowledge and attitude scores were positively correlated (ρ = 0.227, p-value <0.001).

CONCLUSION

Palestinian medical student's knowledge about Alzheimer's disease and dementia is insufficient, with students in the clinical phase showing better understanding than pre-clinical students. The findings highlight a necessity for enhancing the dementia curriculum and conducting further studies to evaluate training's impact on students' knowledge and attitudes.

Dementia Knowledge Among Primary Healthcare Physicians in Riyadh, Saudi Arabia

INTRODUCTION

Dementia poses a significant healthcare challenge globally, and healthcare providers must have adequate knowledge about its diagnosis, management, and support services. By assessing the knowledge level of primary care physicians in Riyadh, we can identify potential gaps and areas for improvement in dementia care, ultimately enhancing patient outcomes and quality of life. This study holds promise in shedding light on the current state of dementia knowledge among primary healthcare physicians in Riyadh and offering insights into strategies to enhance dementia care in this region.

METHODS

This cross-sectional questionnaire-based study was conducted from the first of June 2023 to the end of December 2023 in Riyadh, Saudi Arabia. A validated questionnaire was used to assess physicians' knowledge, attitude, and practice toward dementia.

RESULTS

A total of 151 physicians completed the questionnaires. The majority were male (55%), below 30 years of age (88.1%), and family medicine residents (84.8%). Most (74.8%) recognized old age as the most significant risk factor; an overwhelming majority of participants (98.7%) could not identify the minimum course of treatment to judge a medication's effectiveness. The average score of correct responses (7.74 ∓ 4.11) was equivalent to 38.7%. Furthermore, the average correct responses were significantly different among the different job levels of the participants.

CONCLUSIONS

The findings of this study highlight a lack of knowledge among primary care physicians regarding dementia, emphasizing the crucial importance of physician education in this area. Additionally, the results strongly indicate the need for emphasis on dementia education within the undergraduate medical curriculum, family medicine curriculum, and physician training programs. By addressing these educational gaps, we can better equip physicians to provide optimal care and support for individuals with dementia, ultimately improving patient care and quality of life.

Assessing the Global, Regional, and National Impact of High Body Mass Index on Alzheimer's Disease and Other Dementias Between 1990 and 2019

BACKGROUND

Obesity significantly increases Alzheimer's disease (AD) and dementia risk. Understanding the link between a high body mass index (BMI) and these conditions is crucial for effective management and prevention.

OBJECTIVE

We aimed to estimate the burden of AD and other dementias attributed to high BMI from 1990 to 2019 based on sex, age, and socio-demographic indicators (SDI) at global, regional, and national levels.

METHODS

We collected data on deaths, disability-adjusted life years (DALYs), age-standardized mortality rates (ASMR), and age-standardized DALY rates (ASDR) from the 2019 Global Burden of Disease study for AD and dementia attributed to high BMI. We explored the correlation between SDI levels and ASDR.

RESULTS

In 2019, there were 198,476.2 deaths (95% UI: 32,695.4-593,366.4) and 3,159,912.4 DALYs (848,330.5-8,042,531) attributed to high BMI. Numbers of deaths, DALYs, ASMR, and ASDR increased since 1990. Females had higher deaths, ASMR, and ASDR than males. Mortality and DALYs rates increased with age. ASMR and ASDR increased across five SDI levels, with the highest rise in Low-middle SDI. High-income North America had the most deaths [30,993.9 (5,101.7-89,912.9)], while North Africa and the Middle East had the highest ASMR [4.61 (0.79-13.64)] and ASDR [72.56 (20.98-181.16)] in 2019.

CONCLUSIONS

The burden of AD and other dementias attributed to high BMI increased since 1990 globally and is still heaviest in developed regions. Females accounted predominantly for the burden than males. Timely measures are needed to against high BMI.
