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 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 Department 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.

This phase II/III trial studies how well radiation therapy works when given together with cisplatin, docetaxel, cetuximab, and/or atezolizumab after surgery in treating patients with high-risk stage III-IV head and neck cancer the begins in the thin, flat cells (squamous cell). Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as cisplatin and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cetuximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The purpose of this study is to compare the usual treatment (radiation therapy with cisplatin chemotherapy) to using radiation therapy with docetaxel and cetuximab chemotherapy, and using the usual treatment plus an immunotherapy drug, atezolizumab.

Freezing-of-gait (FoG) in Parkinson Disease (PD) is one of the most vivid and disturbing gait phenomena in neurology. Often described by patients as a feeling of "feet getting glued to the floor," FoG is formally defined as a "brief, episodic absence or marked reduction of forward progression of the feet despite the intention to walk." This debilitating gait phenomena is very common in PD, occurring in up to 80% of individuals with severe PD. When FoG arrests walking, serious consequences can occur such as loss of balance, falls, injurious events, consequent fear of falling, and increased hospitalization. Wearable robots are capable of augmenting spatiotemporal gait mechanics and are emerging as viable solutions for locomotor assistance in various neurological populations. For the proposed study, our goal is to understand how low force mechanical assistance from soft robotic apparel can best mitigate gait decline preceding a freezing episode and subsequent onset of FoG by improving spatial (e.g. stride length) and temporal features (e.g. stride time variability) of walking. We hypothesize that the ongoing gait-preserving effects can essentially minimize the accumulation of motor errors that lead to FoG. Importantly, the autonomous assistance provided by the wearable robot circumvents the need for cognitive or attentional resources, thereby minimizing risks for overloading the cognitive systems -- a known trigger for FoG, thus enhancing the repeatability and robustness of FoG-preventing effects.

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.

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.

This phase II/III trial compares the effect of adding radiation therapy to the usual maintenance therapy with atezolizumab versus atezolizumab alone in patients who have already received atezolizumab plus chemotherapy for the treatment of small cell lung cancer that has spread outside of the lung or to other parts of the body (extensive stage). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving radiation therapy in addition to atezolizumab may extend the time without extensive small cell lung cancer growing or spreading compared to atezolizumab alone.

Chronic pain and heavy drinking are common co-occurring conditions among patients presenting to primary care settings. Given their impact on functioning and medical outcomes, there would be considerable benefit to developing an accessible, easily utilized, integrative approach to reduce alcohol use and pain that can be readily incorporated into the health care settings. The objective of this study is to test a modified version of a smartphone-based intervention for reducing pain and alcohol use among individuals experiencing chronic pain who engage in heavy drinking. The primary goal is to test the feasibility and acceptability of implementing this intervention in a sample that includes participants from rural areas and providing initial data on the utility of the intervention.

The emergence of crawling and walking is significantly delayed in infants with Down syndrome (DS), but the development of independent mobility provides infants with new opportunities for exploring the environment and interacting with objects and people that are important foundations for early learning. Increasing infant mobility early in development with body weight supported harness systems may support infant exploration, communication, and social interaction. This project will set the stage for the first clinical trial of a mobility-related intervention specifically tailored for infants with DS by testing the feasibility of harness systems with infants and families and identifying measures that will serve as primary outcome variables. Upon completion of this pilot project, necessary preliminary data and experience required for an in-home, high-impact clinical trial for infants with DS will have been obtained.

The investigators will conduct the formative work that is necessary to develop a novel, multi-level intervention (inclusive of patient- and provider-level components), which will increase awareness of and modify the complex, intersecting factors that contribute to cervical cancer development among cisgender women with HIV (WWH). In Aim 1a, the investigators will explore the multi-level barriers and facilitators to follow-up appointment attendance among WWH who have had a recent high-risk abnormal Pap smear in the past six months, via qualitative interviews with WWH who have either attended at least one follow-up visit (n<10) or have not yet attended a follow-up visit (n<10). In Aim 1b, the investigators will explore provider awareness of the HIV-cervical cancer relationship and perspectives on barriers to retention in care via qualitative interviews (n<8). For Aim 2, The study team will leverage the Aim 1 data, develop a patient-level intervention (1-2 sessions) and a provider toolkit, with the goal of increasing retention in care among WWH who are at heightened risk for cervical cancer. The study team will seek feedback on the manual and the toolkit from providers and from a community advisory board. In Aim 3a, the investigators will test the feasibility and acceptability of the intervention in a pilot randomized control trial (RCT) (n<60). The study team will also assess (1) changes in self-efficacy to attend cervical cancer-related healthcare appointments pre-post intervention, (2) the proportion of women who attend a follow-up appointment, and, of those participants, (3) the proportion of women who complete the next phase of treatment. In Aim 3b, the investigators will explore the feasibility of intervention implementation in the clinic and acceptability of the provider-level intervention components in qualitative interviews with providers, clinic staff, the interventionalists, and other key stakeholders (n<10).

This study will identify unique signatures that people have which can cause pain by evaluating biological, psychological, and social markers using artificial intelligence. These markers can be used to accurately predict the response of diverse individuals with chronic low back pain (cLBP) to Mindfulness-Based Stress Reduction. This will help enhance clinician decision-making and the targeted treatment of chronic pain. The overall objective is to use a unique machine learning (ML) approach to determine the biomarker signature of persons undergoing mindfulness based stress reduction (MBSR) treatment for their chronic low back pain (cLBP). This signature will facilitate clinical prediction and monitoring of patient response to MBSR treatment. The design of the study is a single-arm clinical trial of the evidence-based MBSR program for patients with cLBP.

This is a 3-year study to test the efficacy of a text message-based intervention program. Dental patients at 4 community health centers (n= 266) will be randomized to receive either text messages (TMs) regarding HIV prevention or TMs regarding overall wellness. Prior to enrolling the 266 participants, the investigators will conduct a feasibility pilot (n=20) to test the TM delivery as well as all study procedures. For both the pilot and the randomized clinical trial (RCT), recruitment will be conducted at 4 Community Health Center dental clinics (Codman Square, East Boston (both East Boston and South End locations), Geiger Gibson, and Upham's Community Health Centers). Recruitment materials (flyers and permission to contact forms) may also be made available at other clinics within the health centers. The study will enroll English and Spanish-speaking patients who have at least one risk factor for HIV but are HIV-negative. Patients enrolled in the pilot will complete self-report surveys at baseline, 1 and 2 months. Participants enrolled in the RCT will complete self-report surveys baseline, 3, 6, and 12 months after baseline; receive and respond to TM assessments during the 6-month intervention.

Lumbar spinal stenosis, a common condition in older adults, can cause pain and difficulty walking (i.e., intermittent neurogenic claudication - INC). Patients with INC not infrequently undergo spinal surgery that fails to help them 1/3-1/2 the time. The purpose of this multi-site feasibility study is to prepare for the conduct of a randomized controlled trial to test the efficacy of manual therapy, exercise, and intramuscular electroacupuncture in reducing pain and improving walking ability for those with INC, and ultimately limiting the need for surgical referrals.

Military service members admitted to inpatient psychiatry for self-injurious thoughts and behaviors (SITBs) represent an at-risk group for continued SITBs and rehospitalizations in the post-discharge period. However, there is an absence of evidence-based interventions designed to be delivered on inpatient psychiatric units to reduce the risk of post-discharge SITBs. To address this gap, the investigator's research group developed Written Exposure Therapy for Suicide Prevention (WET-SP), a brief, scalable, suicide-specific psychotherapy based on the written disclosure paradigm. Written disclosure, in which an individual writes about a personally stressful experience and the related thoughts and feelings, yields improvements across physical and psychiatric domains. Pilot data suggest that written exposure also yields reductions in SITBs. Yet, no study has adapted the written exposure paradigm specifically to target the amelioration of distress associated with suicidal crises and examined whether implementing WET-SP reduces the risk of subsequent SITBs and suicide-related hospitalizations. The primary objective of this randomized controlled trial (RCT) is to evaluate the efficacy of WET-SP, in reducing the incidence and severity of SITBs in active duty military service members following a psychiatric hospitalization due to suicidal ideation, suicide plans, or a suicide attempt. Secondary objectives are to evaluate a potential mechanism of change (i.e., decreases in thwarted belongingness [cf. social disconnectedness]) and moderator of outcomes (i.e., arc of narrative [cf. linguistical parameters of the written narratives generated during treatment]). Participants randomized to WET-SP + TAU will receive five sessions of WET-SP delivered by the study team during their psychiatric hospitalization plus treatment-as-usual (TAU). Participants randomized to TAU will receive daily contact and patient-centered care delivered by the acute psychiatric inpatient unit provider team (e.g., psychiatrists, therapists, case managers). TAU includes psychiatric assessment, initial stabilization, nurse case management, medication management, treatment of medical comorbidities, group and individual therapy, and discharge planning. Outcome assessments will be administered at pretreatment, posttreatment, and 10-, 20-, and 30-week follow-ups.

This randomized trial will evaluate the effect of fenofibrate compared with placebo for prevention of diabetic retinopathy (DR) worsening through 6 years of follow-up in eyes with mild to moderately severe non-proliferative DR (NPDR) and no CI-DME at baseline. In addition to evaluating efficacy, this study aims to evaluate the feasibility of a model for ophthalmologists to prescribe or collaborate with a primary care provider such as an internist/endocrinologist to prescribe and monitor the drug safely. If this study demonstrates that fenofibrate is effective for reducing the onset of proliferative diabetic retinopathy (PDR) or and the results are adopted by the community of retina specialists, a new strategy to prevent vision threatening complications of diabetes could be widely adopted. Widespread use of an oral agent effective at reducing worsening of DR would decrease the numbers of patients who undergo more invasive and much more expensive treatment for DR and who are consequently at risk for side effects that adversely affect visual function. This study will also assess the relationship of glycemic variability, as measured by continuous glucose monitoring with DR outcomes. Ancillary studies will characterize functional and structural outcomes in this cohort.

This phase II trial studies how well lower-dose chemotherapy plus radiation (chemoradiation) therapy works in comparison to standard-dose chemoradiation in treating patients with early-stage anal cancer. Drugs used in chemotherapy, such as mitomycin, fluorouracil, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving chemotherapy with radiation therapy may kill more tumor cells. This study may help doctors find out if lower-dose chemoradiation is as effective and has fewer side effects than standard-dose chemoradiation, which is the usual approach for treatment of this cancer type.

The objectives of this study and registry are to offer the best management possible for patients with brain arteriovenous malformations (AVMs) (ruptured or unruptured) in terms of long-term outcomes, despite the presence of uncertainty. Management may include interventional therapy (with endovascular procedures, neurosurgery, or radiotherapy, alone or in combination) or conservative management. The trial has been designed to test a) whether medical management or interventional therapy will reduce the risk of death or debilitating stroke (due to hemorrhage or infarction) by an absolute magnitude of about 15% (over 10 years) for unruptured AVMs (from 30% to 15%); and, b) to test if endovascular treatment can improve the safety and efficacy of surgery or radiation therapy by at least 10% (80% to 90%). As for the nested trial on the role of embolization in the treatment of Brain AVMs by other means: the pre-surgical or pre-radiosurgery embolization of cerebral AVMs can decrease the number of treatment failures from 20% to 10%. In addition,embolization of cerebral AVMs can be accomplished with an acceptable risk, defined as permanent disabling neurological complications of 8%.
