Sleep Disturbance and Strain Among Caregivers of Persons Living With Dementia
Objective/UNASSIGNED:The study objective was to examine predictors of sleep disturbance and strain among caregivers of persons living with dementia (PLWD). Methods/UNASSIGNED:This cross-sectional study utilized a sample of community-dwelling older adults and their family caregivers drawn from the 2017 National Health and Aging Trends Study and National Study of Caregiving. Multivariable logistic regression was used to assess the association between caregiver and PLWD characteristics and a composite measure of caregiving strain. High caregiving strain was defined as a total score of ≥ 5 on the 6 caregiving strain items (e.g., emotional difficulty, no time for self). We used multivariable proportional odds models to examine predictors of caregiver sleep-related outcomes (trouble falling back to sleep and interrupted sleep), after adjusting for other caregiver and PLWD factors. Results/UNASSIGNED:Of the 1,142 family caregivers, 65.2% were female, 15% were Black, and 14% were Hispanic. Average age was 60 years old. Female caregivers were more likely to report high level of strain compared to male caregivers (OR: 2.61, 95% CI = 1.56, 4.39). Compared to non-Hispanic Whites, non-Hispanic Black and Hispanic caregivers had reduced odds of reporting greater trouble falling back asleep [OR = 0.55, CI (0.36, 0.82) and OR = 0.56, CI (0.34, 0.91), respectively]. The odds of reporting greater trouble falling back asleep was significantly greater among caregivers with high blood pressure vs. caregivers without high blood pressure [OR = 1.62, CI (1.12, 2.33)]. Conclusion/UNASSIGNED:In this cross-sectional study, caregivers with greater sleep difficulty (trouble falling back asleep) were more likely to report having high blood pressure. We found no racial/ethnic differences in interrupted sleep among caregivers to PLWD. These results suggest that interventions to improve sleep among caregivers to PLWD may decrease poor cardiovascular outcomes in this group.

High Precision Mammography Lesion Identification From Imprecise Medical Annotations
Breast cancer screening using Mammography serves as the earliest defense against breast cancer, revealing anomalous tissue years before it can be detected through physical screening. Despite the use of high resolution radiography, the presence of densely overlapping patterns challenges the consistency of human-driven diagnosis and drives interest in leveraging state-of-art localization ability of deep convolutional neural networks (DCNN). The growing availability of digitized clinical archives enables the training of deep segmentation models, but training using the most widely available form of coarse hand-drawn annotations works against learning the precise boundary of cancerous tissue in evaluation, while producing results that are more aligned with the annotations rather than the underlying lesions. The expense of collecting high quality pixel-level data in the field of medical science makes this even more difficult. To surmount this fundamental challenge, we propose LatentCADx, a deep learning segmentation model capable of precisely annotating cancer lesions underlying hand-drawn annotations, which we procedurally obtain using joint classification training and a strict segmentation penalty. We demonstrate the capability of LatentCADx on a publicly available dataset of 2,620 Mammogram case files, where LatentCADx obtains classification ROC of 0.97, AP of 0.87, and segmentation AP of 0.75 (IOU = 0.5), giving comparable or better performance than other models. Qualitative and precision evaluation of LatentCADx annotations on validation samples reveals that LatentCADx increases the specificity of segmentations beyond that of existing models trained on hand-drawn annotations, with pixel level specificity reaching a staggering value of 0.90. It also obtains sharp boundary around lesions unlike other methods, reducing the confused pixels in the output by more than 60%.

Barriers to Vaccination Among People with Parkinson's Disease and Implications for COVID-19
BACKGROUND:Patients with Parkinson's disease (PD) are at higher risk of vaccine-preventable respiratory infections. However, advanced, homebound individuals may have less access to vaccinations. In light of COVID-19, understanding barriers to vaccination in PD may inform strategies to increase vaccine uptake. OBJECTIVE:To identify influenza and pneumococcal vaccination rates, including barriers and facilitators to vaccination, among homebound and ambulatory individuals with PD and related disorders. METHODS:Cross-sectional US-based study among individuals with PD, aged > 65 years, stratified as homebound or ambulatory. Participants completed semi-structured interviews on vaccination rates and barriers, and healthcare utilization. RESULTS:Among 143 participants, 9.8% had missed all influenza vaccinations in the past 5 years, and 32.2% lacked any pneumococcal vaccination, with no between-group differences. Homebound participants (n = 41) reported difficulty traveling to clinic (p < 0.01) as a vaccination barrier, and despite similar outpatient visit frequencies, had more frequent emergency department visits (31.7% vs. 9.8%, p < 0.01) and hospitalizations (14.6% vs. 2.9%, p = 0.03). Vaccine hesitancy was reported in 35% of participants, vaccine refusal in 19%, and 13.3% reported unvaccinated household members, with no between-group differences. Nearly 13% thought providers recommended against vaccines for PD patients, and 31.5% were unsure of vaccine recommendations in PD. CONCLUSION/CONCLUSIONS:Among a sample of homebound and ambulatory people with PD, many lack age-appropriate immunizations despite ample healthcare utilization. Many participants were unsure whether healthcare providers recommend vaccinations for people with PD. In light of COVID-19, neurologist reinforcement that vaccinations are indicated, safe, and recommended may be beneficial.

Conservative kidney management practice patterns in The United States: A ckdopps analysis [Meeting Abstract]
Background: Conservative kidney management (CKM) of kidney failure is an important treatment option for many patients. However, its availability in the United States (US) is not well described. We describe CKM resources and provider practice patterns in US Chronic Kidney Disease (CKD) clinics.
Method(s): Cross sectional analysis of provider surveys (n=22) from unique clinics in the US from the CKD Outcomes and Practice Patterns Study (CKDopps) collected between 2014-2017.
Result(s): Only eight (36%) providers reported involving palliative care in planning for and educating patients about kidney failure. A majority (59%) were extremely comfortable discussing CKM and nearly 100% typically discussed CKM as a treatment option. Nearly all (95%) reported their clinics had the ability to routinely deliver CKM, but only one had a CKM protocol or guideline, and none offered a specific CKM clinic. Most providers said their clinics used the word conservative to describe CKM, with 24% choosing palliative or supportive terminology. Regardless of involvement of PC, most providers estimated that 5% of their patients with or approaching kidney failure were managed with CKM. Patient preference, functional status, frailty, and comorbidities were the most important factors influencing provider decisions in contemplating the suitability of CKM for patients. (Figure 1)
Conclusion(s): Most providers report feeling comfortable discussing CKM, yet almost no clinics report resources or dedicated infrastructure for CKM delivery. Despite reported high frequency of discussing CKM, few patients were described as choosing this treatment pathway. Factors that influence consideration of CKM are consistent with elements that generally influence well-informed geriatric and end-of-life care. Efforts to improve assessment of those elements may allow for more informed recommendations of CKM

Correlates of Cannabis Use Disorders among urban women of color: childhood abuse, relationship with spouse/partner, and media exposure
Objectives/UNASSIGNED:As the rate of cannabis use increases, it is expected that more individuals will develop a Cannabis Use Disorder (CUD). Relatively little is known, however, about the psychosocial correlates of CUDs among racial/ethnic minority women. This study, therefore, examined correlates of CUDs among a cohort of adult African American and Puerto Rican women. Methods/UNASSIGNED:The sample consisted of African American and Puerto Rican female participants (N = 343), who have been followed by the Harlem Longitudinal Development Study from mean age 14 to mean age 39 years. The bivariate and multivariate associations between CUDs at age 39 and variables from 5 domains - demographics, earlier cannabis use, childhood abuse, the relationship with the spouse/partner, and media exposure - were assessed using logistic regression analyses. Results/UNASSIGNED:The results showed that, with the exception of demographic factors, variables from each of the domains (e.g., sexual abuse in childhood, arguments with spouse/partner, and hours of visual media exposure) were related to CUDs at age 39. Conclusions/UNASSIGNED:Findings suggest that in addition to treating CUDs, couples therapy may be indicated to strengthen the spousal/partner relationship, enlist the spouse/partner's support for cannabis use cessation. Furthermore, frequency of visual media exposure may need to be reduced.

CRF serum levels differentiate PTSD from healthy controls and TBI in military veterans
Background and Objective/UNASSIGNED:Posttraumatic stress disorder (PTSD) is a serious and frequently debilitating psychiatric condition that can occur in people who have experienced traumatic stessors, such as war, violence, sexual assault and other life-threatening events. Treatment of PTSD and traumatic brain injury (TBI) in veterans is challenged by diagnostic complexity, partially due to PTSD and TBI symptom overlap and to the fact that subjective self-report assessments may be influenced by a patient's willingness to share their traumatic experiences and resulting symptoms. Corticotropin-releasing factor (CRF) is one of the main mediators of hypothalamic pituitary adrenal (HPA)-axis responses in stress and anxiety. Methods and Results/UNASSIGNED:We analyzed serum CRF levels in 230 participants including heathy controls (64), and individuals with PTSD (53), TBI (70) or PTSD+TBI (43) by enzyme immunoassay (EIA). Significantly lower CRF levels were found in both the PTSD and PTSD+TBI groups compared to healthy control (PTSD vs Controls: P=0.0014, PTSD + TBI vs Controls: P=0.0011) and chronic TBI participants (PTSD vs TBI: P<0.0001PTSD + TBI vs TBI: P<0.0001) , suggesting a PTSD-related mechanism independent from TBI and associated with CRF reduction. CRF levels negatively correlated with PTSD severity on the CAPS-5 scale in the whole study group. Conclusions/UNASSIGNED:Hyperactivation of the HPA axis has been classically identified in acute stress. However, the recognized enhanced feedback inhibition of the HPA axis in chronic stress supports our findings of lower CRF in PTSD patients. This study suggests that reduced serum CRF in PTSD should be further investigated. Future validation studies will establish if CRF is a possible blood biomarker for PTSD and/or for differentiating PTSD and chronic TBI symptomatology.

Chronic disease stigma, skepticism of the health system, and socio-economic fragility: Qualitative assessment of factors impacting receptiveness to group medical visits and microfinance for non-communicable disease care in rural Kenya
BACKGROUND:Non-communicable diseases (NCDs) are the leading cause of mortality in the world, and innovative approaches to NCD care delivery are being actively developed and evaluated. Combining the group-based experience of microfinance and group medical visits is a novel approach to NCD care delivery. However, the contextual factors, facilitators, and barriers impacting wide-scale implementation of these approaches within a low- and middle-income country setting are not well known. METHODS:Two types of qualitative group discussion were conducted: 1) mabaraza (singular, baraza), a traditional East African community gathering used to discuss and exchange information in large group settings; and 2) focus group discussions (FGDs) among rural clinicians, community health workers, microfinance group members, and patients with NCDs. Trained research staff members led the discussions using structured question guides. Content analysis was performed with NVivo using deductive and inductive codes that were then grouped into themes. RESULTS:We conducted 5 mabaraza and 16 FGDs. A total of 205 individuals (113 men and 92 women) participated in the mabaraza, while 162 individuals (57 men and 105 women) participated in the FGDs. In the context of poverty and previous experiences with the health system, participants described challenges to NCD care across three themes: 1) stigma of chronic disease, 2) earned skepticism of the health system, and 3) socio-economic fragility. However, they also outlined windows of opportunity and facilitators of group medical visits and microfinance to address those challenges. DISCUSSION/CONCLUSIONS:Our qualitative study revealed actionable factors that could impact the success of implementation of group medical visits and microfinance initiatives for NCD care. While several challenges were highlighted, participants also described opportunities to address and mitigate the impact of these factors. We anticipate that our approach and analysis provides new insights and methodological techniques that will be relevant to other low-resource settings worldwide.
