Background And Objectives: People living with dementia experience progressive functional decline and increased dependence on caregivers. This study examined the influence of caregivers' dementia health literacy on perceptions of medical care preferences and advanced care planning (ACP) in people living with dementia.

Research Design And Methods: This analysis used data from a cross-sectional survey, "Care Planning for Individuals with Dementia", administered nationwide by Alzheimer's Disease Centers. We conducted binary, ordinal, and multinomial logistic regression.

Results: On average, surveyed caregivers (n=431) were 78.3 years, had 16 years of education, and were mainly white (88.5%). Most lived with (76.8%) and were the designated healthcare proxy (95.1%), with high dementia knowledge scores (mean=8.4/10). As caregivers' dementia knowledge scores increased, they were 1.27 times more likely (p=0.02) to endorse comfort care. Caregivers with greater knowledge about severe dementia were less likely to need further treatment preference-related discussions (knowing a lot: OR=0.17, p<0.001; knowing some things: OR=0.37, p=0.006). Caregivers live apart from patients were 2.71 times more likely to know about such discussions (p<0.001). Caregivers of people in earlier stages endorsed greater needs for further conversations with clinicians (no impairment & MCI: OR=7.38, p=0.002; mild impairment: OR=5.32, p=0.005) and their care recipients (no impairment & MCI: OR=5.24, p=0.02).

Discussion And Implications: These findings highlight the role of dementia-specific education in ACP discussions among people living with dementia, caregivers, and healthcare clinicians. These findings are important since evidence suggests that ACP may promote quality of life, reduce iatrogenic harm, minimize healthcare overutilization, and alleviate care-related burdens.

Violence experience, interpersonal and community-level, is commonly reported by people living with HIV (PLWH). Understanding the impact of the various forms of violence on HIV outcomes is critical for prioritizing violence screening and support resources in care settings. From February 2021 to December 2022, among 285 PLWH purposively sampled to attain diversity by gender, race/ethnicity, and HIV care retention status in Atlanta, Georgia, we examined interpersonal and community violence experiences and proxy measures of violence (post-traumatic stress disorder (PTSD), anxiety, depression) and their associations with HIV outcomes (engagement and retention in care and HIV viral suppression) using multivariable analysis.

Background: Non-communicable diseases (NCDs) are the leading cause of death globally, and many humanitarian crises occur in countries with high NCD burdens. Peer support is a promising approach to improve NCD care in these settings. However, evidence on peer support for people living with NCDs in humanitarian settings is limited.

Background: No study has assessed the impact of flavor capsule cigarettes (FCCs) on smoking cessation. Thus, the purpose of this exploratory study was to assess (1) the sociodemographic and smoking-related characteristics associated with using FCCs, and (2) the preliminary impact of FCCs on smoking cessation.

Methods: This study is a secondary data analysis of a single-arm study with 100 individuals living in Mexico who smoked and received a smoking cessation mHealth intervention and pharmacotherapy support.

Introduction: Dengue is one of the most widespread arboviruses in Latin America and is now affecting areas previously free of transmission. The COVID-19 pandemic and climatic variations appear to have affected the incidence of the disease, abundance of vectors and health programs related to dengue in some countries.

Objective: To analyze the epidemiology of dengue in Paltas, Ecuador (2016-2022), compare the periods before and during the COVID-19 pandemic, examine entomological reports and discuss the possible implications of the COVID-19 pandemic and climatic variations.

Background: The aim of the SURECAN trial is to evaluate a person-centred intervention, based on Acceptance and Commitment Therapy (ACT Plus ( +)), for people who have completed treatment for cancer with curative intent, but are experiencing poor quality of life. We present the statistical analysis plan for assessing the effectiveness and cost-effectiveness of the intervention in improving quality of life 1 year post randomisation.

Methods And Design: SURECAN is a multi-centre, pragmatic, two-arm, partially clustered randomised controlled superiority trial comparing the effectiveness of ACT + added to usual care with usual aftercare.
