Background:Large and diverse dementia patient cohorts can further a variety of research programs aimed at improving diagnosis, treatment, and meaningful survival in AD. Method: We recruited 1,502 dementia patients between 1989 and 2002, subclassified using standardized criteria and laboratory procedures, and treated according to established guidelines. Baseline clinical and psychometric measures were repeated annually, in person or by use of a multi-modal telephone follow-up program that included many of the measures obtained at in-person visits. We tracked vital status of all subjects at 6-month intervals and offered autopsies to all participants. We assessed for cohort effects in baseline characteristics by 2-year intervals, examined the characteristics and outcomes for those who remained active compared to those who were eventually lost to follow-up, examined survival times for demographic or diagnostic subgroups, and assessed the accuracy of clinical diagnoses versus neuropathology. Results: The average age at entry, average educational level, and baseline MMSE scores for subjects are increasing over time, and probable AD diagnoses are also increasing. Most (80.6%) subjects have remained active in our Center; those who did not were more likely to have a non-AD diagnosis. Survival averages 5.2 years (CI 4.98–5.37) and is influenced by age and gender, but not by diagnosis of probable versus possible AD. Our diagnostic accuracy is 89.6%, with high sensitivity to the presence of AD (96%). Conclusions: In a large and representative clinical cohort, the demographics of AD are changing over time. Careful analyses of those who continue and those who drop out from follow-up suggest that atypical diagnosis, rather than severity or demographic issues accounts for most of the attrition. Clinicians are likely to encounter increasingly older patients with milder disease, and these trends have implications for the design of clinical trials. Survival from the onset of first symptoms, similar for probable and possible AD cases, may be increasing over time.

Background High rates of unintended adolescent pregnancy are a significant health problem in Uganda. To improve access to family planning (FP) services, community-based Village Health Teams (VHTs) are widely employed in Uganda to deliver education and services. However, evaluations of FP programs suggest that mainly older, married women use VHT FP services. Methods To better understand youth reluctance to use VHTs, we collected quantitative FP and contraceptive-seeking behavior data from a survey of 250 youths aged 15–25 in randomly selected households in Nakaseke District, which we triangulated with data from 3 focus group discussions (FGDs) (n = 15). Results Most respondents received FP services from the formal health sector, not VHTs. Only half had talked to a VHT, but 65% knew that VHTs provide free FP services, and most (82%) felt comfortable talking to VHTs about FP. The main reasons for discomfort were fear that VHTs would violate privacy (mentioned by 60% of those not comfortable), that VHTs would talk to parents (33%), shyness (mentioned by 42% of those ≤18), and fear of being judged (14%). Concern about side effects was the most common reason for not using FP methods. Survey respondents said having VHTs of the same sex was important, particularly those in the youngest age group (OR = 4.45; 95%CI: 1.24, 16.00) and those who were unmarried (OR = 5.02; 95%CI: 2.42, 10.39). However, FGD participants (who were older than survey respondents on average) often preferred older VHTs of the opposite sex, whom they viewed as more professional and trustworthy. Respondents said the primary deciding factors for using VHTs were whether privacy would be respected, the proximity of care, and the respectfulness of care. Conclusions VHTs are a known source of FP services but not widely used by youth due to privacy and quality of care concerns. VHT messaging and training should increase focus on ensuring privacy, protecting confidentiality, providing respectful care, and addressing concerns about contraceptive side effects. Preferences for VHTs of similar age and sex may be more important for younger adolescents than older youths for whom quality concerns predominate.
