Intracranial Atherosclerotic Disease and Incident Dementia: The ARIC Study (Atherosclerosis Risk in Communities).

BACKGROUND: Studies of the neurovascular contribution to dementia have largely focused on cerebral small vessel disease (CSVD), but the role of intracranial atherosclerotic disease (ICAD) remains unknown in the general population. The objective of this study was to determine the risk of incident dementia from ICAD after adjusting for CSVD and cardiovascular risk factors in a US community-based cohort. METHODS: We acquired brain magnetic resonance imaging examinations from 2011 through 2013 in 1980 Black and White participants in the ARIC study (Atherosclerosis Risk in Communities), a prospective cohort conducted in 4 US communities. Magnetic resonance imaging examinations included high-resolution vessel wall magnetic resonance imaging and magnetic resonance angiography to identify ICAD. Of these participants, 1590 without dementia, without missing covariates, and with adequate magnetic resonance image quality were followed through 2019 for incident dementia. Associations between ICAD and incident dementia were assessed using Cox proportional hazard ratios adjusted for CSVD (characterized by white matter hyperintensities, lacunar infarctions, and microhemorrhages), APOE4 genotype (apolipoprotein E gene ε4), and cardiovascular risk factors. RESULTS: The mean age (SD) of study participants was 77.4 (5.2) years. ICAD was detected in 34.6% of participants. After a median follow-up of 5.6 years, 286 participants developed dementia. Compared with participants without ICAD, the fully adjusted hazard ratios (95% CIs) for incident dementia in participants with any ICAD, with ICAD only causing stenosis ≤50%, and with ICAD causing stenosis >50% in ≥1 vessel were 1.57 (1.17-2.11), 1.41 (1.02-1.95), and 1.94 (1.32-2.84), respectively. ICAD was associated with dementia even among participants with low white matter hyperintensities burden, a marker of CSVD. CONCLUSIONS: ICAD was associated with an increased risk of incident dementia, independent of CSVD, APOE4 genotype, and cardiovascular risk factors. The increased risk of dementia was evident even among participants with low CSVD burden, a group less likely to be affected by vascular dementia, and in participants with ICAD causing only low-grade stenosis. Our results suggest that ICAD may partially mediate the effect that cardiovascular risk factors have on the brain leading to dementia. Both ICAD and CSVD must be considered to understand the vascular contributions to cognitive decline.

Knowledge, attitudes, and practices related to dengue among public school teachers in a Central Luzon Province in the Philippines: an analytic cross-sectional study.

BACKGROUND: Dengue has become a major health issue in tropical regions as the numbers of reported cases and estimated infections continuously increase. In the Philippines, many challenges remain in preventing and controlling the disease amidst all the mitigation efforts of the government. This study sought to measure the health literacy of Filipino teachers and determine the associations among teachers' knowledge, attitudes, and selected practices (KAP) against dengue. METHODS: Elementary and secondary school teachers from the consistently declared dengue hotspots in the City of San Fernando, Pampanga, Philippines, from the years 2017 to 2019 were selected as target participants in this cross-sectional study. A self-administered online survey tool was used in this study for both screening of participants and the KAP survey proper. STATA, descriptive statistics, and multiple logistic regression were used for the data analysis. Odds Ratios (ORs) and 95% confidence intervals (CIs) were reported. RESULTS: The study comprised 604 participants whose mean age was 38.4 years. Television was determined as the top media source of information, and various health staff were the most trusted and common source of information. Good knowledge on dengue treatment (OR = 1.81; 95% CI 1.18-2.78) and dengue prevention (OR = 1.85; 95% CI 1.26-2.71) were positively associated with having good practices on protection against mosquito bites. Good knowledge on dengue signs and symptoms (OR = 1.56; 95% CI 1.02-2.37) and dengue prevention (OR = 2.38; 95% CI 1.59-3.58) were positively associated with having good practices on preventing breeding sites. Those with positive perceived susceptibility to dengue had lower odds of having good practices on protection against mosquito bites (OR = 0.64; 95% CI 0.41-0.99) and of having good practices on preventing breeding sites (OR = 0.46; 95% CI 0.26-0.81). CONCLUSION: Even with the existing dengue policies, programs, and strategies, and the high disease literacy rate of Filipinos, dengue remains a struggle with an increasing case rate. Therefore, specific concepts should be emphasized, and interventions should be fine-tuned to better reach and influence the target population to attain a dengue-free Philippines.

Intimate Partner Violence and Sexual Agency in a Nationally Representative Sample of Women and Girls in the Philippines.

This study examined the prevalence of intimate partner violence (Intimate Partner Violence) and its associations with sexual agency among women and adolescent girls in the Philippines. Data came from the 2017 Philippines National Demographic and Health Survey (DHS), a nationally representative, cross-sectional survey of women and girls ages 15-49. Participants included 11,727 women and girls who reported having a current male partner. Survey measures included three indicators of Intimate Partner Violence (physical, sexual, emotional), ability to refuse sex, ability to insist on condom use, perception that a husband/boyfriend can be justified in hitting or beating his wife/girlfriend, and sociodemographic characteristics. Descriptive and multivariable statistical analyses were conducted, with survey weightings used to account for the complex survey design. Overall, 23.9% reported Intimate Partner Violence in their current partnership (10.1% physical violence, 3.4% sexual violence, 19.0% emotional violence), 11.2% believed a husband or partner could be justified in hitting or beating their wife, 10.5% reported being unable to refuse sex with their partner, and 20.4% were unable to ask their partner to use a condom. In multivariable analyses, experiences of sexual (OR .68; 95% CI .50, .92), physical (OR .83; 95% CI .68, 1.02), and emotional violence (OR .69; 95% CI .58, .81) were associated with lower adjusted odds of being able to ask a partner to use a condom. When placed in the same model, emotional violence had the strongest association with lower odds of negotiating condom use with partner (OR .70; 95% CI .57, .85). Perception that a husband/boyfriend can be justified in hitting or beating his wife/girlfriend was associated with lower ability to refuse sex and ask a partner to use a condom. Findings indicate a need for further investment in interventions to prevent Intimate Partner Violence and support the sexual health and agency of women and girls who have experienced Intimate Partner Violence in the Philippines.

Responsive Medical Providers and Recent HIV Medical Services Engagement Among Transgender Women and Cisgender Men Who Have Sex With Men in the Philippines.

Transgender women and cisgender men who have sex with men (trans-WSM and cis-MSM) comprise the majority of new HIV infections in the Philippines. There is limited research in the Philippines on the relationship between having a provider responsive to the needs of these populations and recent engagement in HIV medical services such as HIV testing and treatment. We used multivariate logistic regression to examine the relationship between having a responsive medical provider and engagement in HIV medical services in the past 12 months among an online sample of 318 trans-WSM and cis-MSM in the Philippines. Participants without a responsive medical provider had lower adjusted odds of recent HIV medical service engagement than those who did (aOR = 0.32, 95% CI [0.16, 0.62], p = .00). In stratified analyses, this relationship was significant for trans-WSM but not cis-MSM. Increasing access to responsive providers in the Philippines could bolster recent engagement with HIV medical services.

Transgender-specific developmental milestones and associated experiences of violence, discrimination, and stigma among Filipinx transgender women who are sexually active with men.

BACKGROUND: For transgender people, reaching transgender (trans)-specific developmental milestones, including recognizing and expressing one's identity, plays an integral role in overall health, wellbeing, and the pursuit of gender affirmation. Yet trans people continue to face minority stressors, including structural violence (i.e., discrimination, violence, and stigma), which may interfere with the achievement of these milestones. Among trans women specifically, however, potential associations between gender developmental milestones and structural violence are not well characterized in the literature. In a sample of Filipinx (i.e., an inclusive term for describing non-binary genders in the Philippines) trans women who are sexually active with men (trans-WSM), we thus sought to: (a) describe the mean ages at which gender developmental milestones occur and (b) examine the associations between structural violence and mean ages at which at which Filipinx trans-WSM experience trans-specific developmental milestones. METHODS: Using data from Project #ParaSaAtin, an online survey of Filipinx trans-WSM (n = 139), we mapped age-estimates per trans-specific milestones and then tested whether structural violence is associated with the mean age at which trans women experience trans-specific developmental milestones. RESULTS: Overall, participants who reported higher levels of discrimination, stigma, and violence also experienced a later age for nearly each milestone (i.e., initial self-awareness of transfeminine identity, transfeminine expression in private, transfeminine expression in public, first consensual oral/vaginal/anal sex with a cisgender male partner, first consensual oral/vaginal/anal sex with a cisgender male partner as a trans women, and hormone integration) (all p-values <0.05). Of note, the single exception to this pattern was the non-significant association between stigma and initial disclosure of transfeminine identification to another person. CONCLUSION: Results are consistent with psychological literature outlining a temporal sequence of developmental milestones among young trans-WSM. For young trans-WSM in the Philippines, data from this study demonstrate significant associations between structural violence and the achievement of developmental milestones. These findings highlight the need for trauma-informed, strengths-based programming and institutional policies that measure and mitigate anti-trans violence.

Detecting Local Clusters of Under-5 Malnutrition in the Province of Marinduque, Philippines Using Spatial Scan Statistic.

Underweight and overweight among under-5 children continue to persist in the island Province of Marinduque, Philippines. Local spatial cluster detection provides a spatial perspective in understanding this phenomenon, specifically in which areas the double burden of malnutrition occurs. Using data from a province-wide census conducted in 2014-2016, we aimed to identify spatial clusters of different forms of malnutrition in the province and determine its relative risk. Weight-for-age z score was used to categorize the malnourished children into severely underweight, moderately underweight, and overweight. We used the multinomial model of Kulldorff's elliptical spatial scan statistic, adjusting for age and socioeconomic status. Four significant clusters across municipalities of Boac, Buenavista, Gasan, and Torrijos were found to have high risk of overweight and underweight simultaneously, indicating existence of double burden of malnutrition within these communities. These clusters should be targeted with tailored plans to respond to malnutrition, at the same time maximizing the resources and benefits.
