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.

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 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.

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.

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%.

This phase III trial compares the effect of adding a stem cell transplant with melphalan after completing chemotherapy with daratumumab, cyclophosphamide, bortezomib and dexamethasone (Dara-VCD) versus chemotherapy with Dara-VCD alone for treating patients with newly diagnosed amyloid light chain (AL) amyloidosis. Melphalan is a chemotherapy given prior to a stem cell transplant. Giving chemotherapy before a peripheral blood stem cell transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. The stem cells are then returned to the patients to replace the blood forming cells that were destroyed by the chemotherapy. Daratumumab is in a class of medications called monoclonal antibodies. It binds to a protein called CD38, which is found on some types of immune cells and cancer cells, including myeloma cells. Daratumumab may block CD38 and help the immune system kill cancer cells. Chemotherapy drugs, such as cyclophosphamide and bortezomib, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Dexamethasone is in a class of medications called corticosteroids. It is used to lower the body's immune response to help stop the growth of cancer cells. Giving a stem cell transplant with melphalan after Dara-VCD may kill more cancer cells in patients with newly diagnosed AL amyloidosis.

SARS-CoV-2 transmission was expected to have a devastating impact in sub-Saharan African countries. Instead, morbidity and mortality rates in nearly the whole region are an order of magnitude lower than in Europe and the Americas. To identify what is different requires a better understanding of the underlying immunological substrate of the population, and how these factors affect susceptibility to infection, progression of symptoms, transmission, and responses to SARS-CoV-2 vaccination. Study objectives 1. Determine the risk and predictors of infection and disease among contacts of SARS-CoV-2 infection subjects in Malawi 2. Determine whether innate immune responses lower the risk of SARS-CoV-2 infection and disease, and acquisition and duration of vaccine responses. 3. Assess whether alterations in innate immune responses relevant to SARS-CoV-2 are associated with malaria or intestinal parasite infections. 4. Assess the acquisition and longevity of antibodies (Ab) and cellular adaptive responses elicited by SARS-CoV-2 infection and vaccination. 5. Assess whether malaria and intestinal parasite infections, chronic/mild undernutrition, and anemia mediate alterations in Ab and other adaptive cellular responses to SARS-CoV-2 through innate immune responses or a different unknown mechanism.

This pilot randomized double blind controlled crossover study aims to determine the impact of two wrist cooling devices on symptom control of hot flashes in adult men and adult women experiencing hot flashes. The participants will record during the first two weeks of the study all of their hot flashes and severity of their hot flashes in a diary. The participants will be randomly assigned to wear one of the two wrist cooling devices that have an identical appearance at different times in the study. They will wear the first assigned device for weeks 3 and 4. They will record in their diary the severity of their hot flashes while using the device. For weeks 5 and 6 they will be ask to use a second device and record in their diary the severity of their hot flashes with the use of the device. The devices will be attached to the wrist like a watch. When activated, one device will turn on a cooling fan with the cooling plate being active for up to 5 minutes, and the other device will turn on a cooling fan only for up to 5 minutes without the cooling plate being active.

This collaborative screening protocol, developed by the Lung Cancer Mutation Consortium (LCMC) and supported by the Thoracic Surgery Oncology Group (TSOG), is designed to determine the feasibility of comprehensive molecular profiling to detect actionable oncogenic drivers in patients with suspected early stage lung cancers scheduled to undergo biopsies to establish the diagnosis of lung cancer. The primary purpose of this testing is to determine the presence of 12 oncogenic drivers (mutations in EGFR, BRAFV600E , MET exon 14, KRAS G12C and HER2, rearrangements in ALK, RET, NTRK, EGFR exon 20 insertion and ROS1, and amplification of MET and HER2) that can serve as targets making patients eligible for upcoming targeted neoadjuvant therapy trials. The ultimate goal is to use this information from the screening process to select the optimal neoadjuvant therapy and wherever possible enroll patients onto separate neoadjuvant therapy trials with genomically matched treatments or other appropriate trials if no actionable driver mutation is detected. Thoracic Surgery Oncology Group (TSOG) is a network of surgeons within North American Thoracic Surgery Academic Centers aligned with the goal of enhancing patient care through administration of multi-site trials focused on recent advances in lung cancer. TSOG has aligned with the LCMC4 sites to enroll the LCRF-LEADER screening trial. TSOG's involvement will be essential in trial enrollment and ultimate interpretation of the multimodal clinical and translational data collected as part of this study. We estimate we will detect an actionable oncogenic driver in 33% of cases. The remaining 66% of patients will represent a cohort identified by their care teams as candidates for other potential neoadjuvant therapies which may include checkpoint inhibitors such as atezolizumab, durvalumab, nivolumab, and pembrolizumab or other novel agents. The targeted therapy treatment trials will be conducted independently of the LCRF-LEADER screening trial, evaluating for efficacy. If none of the 10 oncogenic drivers are detected, the patient will be offered participation in any clinical trial of neoadjuvant therapy available at their treating institution or standard of care therapy. For patients not enrolled on a targeted treatment trial, circulating tumor DNA in blood (ctDNA) will be collected at 3 time points: before neoadjuvant treatment, after neoadjuvant treatment but before surgery, and after surgery. This initiative will be correlated with various clinical outcomes. Prespecified clinical data will be collected for correlation with these circulating biomarkers.

Pakistan is facing a massive rise in drug abuse. According to recent estimates, there are 6.7 million drug abusers, of which 4.25 million are drug dependents who need long-term treatments in residential setups. Despite these shocking statistics, there is a severe lack of evidence-based treatment, preventive measures, and drug indictment policies. Consequently, the number of drug dependents continues to increase at an alarming rate of 40,000 per year, making Pakistan one of the most drug-affected countries in the world. The ever-increasing rise in drug abuse can be devastating for a country such as Pakistan where the youth population (aged <30 years) makes up a substantial 64% of the total population. It not only affects the individual's physical and mental health but also casts devastating effects on the psycho-social and economic aspects of their lives. Adults with Substance Use Disorders (SUDs) usually come across aggravated interpersonal and family problems, loss of productivity and unemployment, poverty and crimes, overall financial problems, deaths, and accidents. Furthermore, it also destroys the norms, morality, worth, and dignity of the person's well-being and effectiveness in the growth of society. Numerous studies in Pakistan showed a lack of evidence-based treatment altogether for adults suffering from SUDs. Thus, effective interventions for SUDs that also meet the clinical reality of open treatment groups are much needed to reduce the treatment gap. Further, the implementation of evidence-based approaches like Cognitive Behavior Therapy (CBT) has an advantage with SUDs clients who are motivated. The proposed project aims at the cultural adaptation of CBT-based group intervention for adults with substance use disorders (SUDs) in Pakistan by employing a Quasi-Experimental research design, followed by Randomized Control Trials to test its effectiveness in Pakistan.
