To achieve global goals for the treatment of HIV, most high-prevalence countries are experimenting with and scaling up differentiated service delivery models (DSD). A handful of efforts have been formally described and evaluated in the literature; many others are being implemented formally or informally under routine care, without a research or evaluation goal. For most countries, however, we have little evidence on the big picture-the proportion of clinics offering alternative models, eligibility criteria and the proportion of patients considered eligible, the number of patients actually participating, health outcomes such as viral suppression, empirical resource utilization compared to traditional care, variations among the models, duration of patient participation, fidelity to model guidelines, effects on clinic efficiency, and sustainability without external donor support. AMBIT is a set of data synthesis, data collection, and data analysis activities aimed at generating information for near- and long-term decision making and creating an approach and platform for ongoing evaluation of differentiated models of HIV treatment delivery in the future. The project will collect and analyze a wide range of existing data sets pertinent to DSD. This protocol is for an analysis of existing medical record data collected by the Ministry of Health, implementing partners, and other completed, ongoing, or new evaluations, trials, and observational studies. Outcomes to be reported include coverage/uptake of DSD, patients' outcomes, and distribution of each model. There will be no study interaction with individual patients, providers, caregivers, or others for this analysis. Type: Observational Start Date: Dec 2019 |

Stroke is among the leading causes of long-term disability worldwide. Post-stroke neuromotor impairments are heterogeneous, yet often result in reduced walking ability characterized by slow, asymmetric, and unstable gait patterns. Rhythmic Auditory Stimulation (RAS) is an emerging rehabilitation approach that leverages auditory-motor synchronization to retrain neuromotor control of walking. Indeed, walking with RAS can enhance walking rhythmicity, gait quality, and speed. RAS is a potentially valuable tool for walking rehabilitation after stroke; however, despite extensive research evidence on the overall benefits of RAS in people with chronic stroke, the notable variability in the walking characteristics of individual patients is likely to influence the effectiveness of RAS intervention, and thus requires study. Furthermore, beyond stroke-related factors, age-related changes may also affect how well individuals post-stroke respond to RAS. This study aims to recruit 24 individuals post-stroke and 20 older adults to evaluate the effects of stroke- and age-related neuromotor impairment on RAS intervention. Each study participant will complete two six-minute walk tests: one without RAS (baseline) and the other with RAS delivered using a metronome. The investigators hypothesize that post-stroke individuals will, on average, exhibit a positive response to RAS intervention (i.e., walk farther and with greater gait automaticity (i.e., reduced stride time variability), with the degree of response predicted by specific baseline characteristics. Furthermore, the investigators anticipate that these walking enhancements will be accompanied by improvements in gait biomechanics and a reduction in the metabolic cost of walking. The investigators hypothesize that older adults will exhibit similar, but attenuated, effects of RAS. Type: Interventional Start Date: Sep 2023 |

Undernutrition is a leading global risk factor of tuberculosis (TB) and a prevalent comorbidity associated with TB. In Benin, the National TB Program systematically provides nutritional support to all persons with TB (PWTB), distributing prepared foods to hospitalized patients and food baskets during outpatient care. In Togo, the PWTB population is similar to that of Benin; however, Togo does not have a systematic program in place to provide nutritional support to these patients. The investigators will perform a prospective cohort analysis using anonymized TB patient data from the National TB Programs of Benin and Togo. Participants enrolled in Benin will receive nutritional support from the hospital while those enrolled in Togo will not. Participants in Togo who do not receive nutritional support will serve as a control. Unfavorable outcomes in both groups such as treatment failure, death, or relapse will be compared. The results from this study should help to shape TB programs in the future by incorporating nutritional support. Type: Observational Start Date: Sep 2023 |

Scleroderma (SSc) is an autoimmune disease characterized by fibrosis (or collagen deposition) of the skin and internal organs. The extent of skin fibrosis is an important predictor of internal organ complications and increased mortality. Currently imprecise and subjective methods that varies amongst different doctors for the same patient are available to quantify skin fibrosis in patients, by "pinching" their skin and assessing how thick it is; this is the method used to determine the modified Rodnan skin score (mRSS). Skin thickness and the amount of fibrosis can change over time due to disease progression or in response to therapy. In this research, longitudinal measurements will be taken to determine if spatial frequency domain imaging (SFDI) can detect changes in skin thickness that occur over time in response to therapy or from disease progression in scleroderma patients. This study will compare SFDI with other clinical outcome assessments of skin thickness and fibrosis in scleroderma patients including mRSS, skin biopsy histology, scleroderma skin patient reported outcome (SSPRO), ultrasound, and durometry (durometer measures skin hardness). SFDI information will also be compared with capillaroscopy (allows for non-invasive imaging of the nailfold capillaries) if available from the electronic medical record. If SFDI correlates well with other clinical outcome assessments, it may be used in the future as a rapid, non-invasive tool for monitoring disease activity in scleroderma patients.

This is a randomized clinical trial (RCT) to assess the efficacy of bariatric surgery vs medical weight loss vs. the "usual standard of care" to optimize a morbidly obese patient with end-stage osteoarthritis of the hip or knee joint for total joint arthroplasty (TJA). The study population will include patients with hip or knee joint osteoarthritis and BMI (Body Mass Index) > 40 kg/m2 who are evaluated in the joint arthroplasty clinic at Boston Medical Center. The primary objective of the study is to determine if bariatric surgery or medical weight loss is more effective than the usual standard of care in optimizing a morbidly obese patient with osteoarthritis of the hip or knee joint for TJA. This will be determined by comparing the number of patients within each group who are able to lose weight through either bariatric surgery, medical weight loss, or the usual standard of care to achieve a BMI ≤ 40 kg/m2 to eventually undergo TJA. The secondary objectives of this study are to compare total operative time, postoperative complication rates, readmission rates, percentage of total body weight lost, revision rate, and reoperation rate. The ability of patients within each study arm to maintain a BMI ≤ 40 kg/m2 for up to 2 years after undergoing TJA will also be assessed, as well as their level of satisfaction before and after being in the study.

Alcohol use is a significant problem among Latinxs and immigration-related stress increases risk for substance use. A theoretically-based cultural adaptation of motivational interviewing (CAMI) that specifically integrated discussion of immigration-related stressors (e.g., stigma, social isolation) resulted in significant reductions in alcohol-related harms for those Latinx heavy drinkers with high discrimination compared to standard MI, and reduced anxiety and depressive symptoms one year later compared to MI. Rigorous tests that examine theoretically-informed adaptation of efficacious addiction interventions are not common, yet are needed to advance implementation science. This Hybrid Type 1 Effectiveness-Implementation study will investigate the feasibility of implementing CAMI in a real-world clinical setting. The key questions are: Would CAMI have positive effects among individuals who use both drugs and alcohol? How do providers view this intervention? The investigators will collaborate with a primary care center that serves a mainly Latinx client population to train their Community Wellness Advocates (CWAs) to deliver CAMI to patients who are heavy drinkers. The investigators will conduct a concurrent investigation on the process of implementing CAMI in primary care - a two-arm randomized clinical effectiveness trial will enroll Latinx heavy drinkers (18 years or older) in primary care who use alcohol (and may use other drugs) - and follow them for 12 months after the intervention. Specific Aims are: (1) To examine the impact of CAMI plus a booster session (vs. assessment only) on outcomes: % heavy drinking days, frequency of alcohol-related consequences, depressive/anxiety symptoms, and number of illicit drug use days, using a Hybrid Type 1 Effectiveness-Implementation design and (2) To gather indicators of implementation outcome from multiple stakeholders using a mixed-methods approach. The investigators will follow Curran's framework to evaluate the process of implementation and Proctor's framework to measure implementation outcomes. This study, a first to examine the acceptability of culturally-adapted addiction treatments in primary care settings, will answer essential questions on implementing evidence-based care for Latinxs that can improve health disparities related to substance use. Long term goals are to translate the lessons from this Hybrid study to the broader community to focus on population health for all primary care patients. Type: Interventional Start Date: Mar 2022 |

Mutual exclusivity is a word learning constraint in which the learner assumes that a given word refers to only one category of objects. In spoken languages, mutual exclusivity has been demonstrated in monolingual children as young as 17 months and cross-linguistically, while multilingual learners show an attenuated mutual exclusivity bias. Mutual exclusivity has not been robustly demonstrated in deaf children acquiring American Sign Language (ASL). Further, it is unclear if mutual exclusivity applies to those learning both a signed and a spoken language. Like unimodal bilinguals, bimodal bilingual (BiBi) children learn two words for an object, but these words are separated by modality. A BiBi child could therefore assume that all objects have two words (like unimodal bilinguals) or that all objects have one spoken word and one sign (within-modality mutual exclusivity). The goals of the current study are to demonstrate mutual exclusivity in monolingual deaf children acquiring ASL, and to determine if BiBi deaf children utilize mutual exclusivity within each modality.
