A prospective pilot study examining nutritional supplements among vascular surgery patients with Critical Limb Ischemia (CLI). CLI patients have a high rate of malnutrition and has the potential to benefit greatly from nutritional intervention. The investigators plan to evaluate nutrition and functional status of patients by assessing objective lab values and the use of the hand grip strength test. Providing perioperative nutritional supplements to patients has potentially improved their nutritional status, which in turn may improve the patient's clinical status after surgery.

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.

While numerous studies have assessed the promising impacts of prehabilitation, there is a lack of prehabilitation research within lower socioeconomic patient populations. Often for prehabilitation studies, patients are heavily involved in full scale exercise and nutrition programs weeks before the scheduled procedure. In underserved populations, programs such as these are often not feasible due to lack of transport, resources, and other barriers to healthcare. The investigators seek to evaluate the effectiveness of inexpensive interventions in lower socioeconomic populations. The investigators hypothesize that barriers to prehabilitation are environmental and that prehabilitation interventions tailored for lower socioeconomic (SES) populations will improve time to discharge, mobility, and in turn, readmission rates. The participants for this clinical trial will be seen four times: initially at the preoperative surgical clinic (6-8 weeks prior to surgery), 1-2 days preop at a pre-procedure clinic, postoperative in the inpatient setting (as soon as the participant is able to ambulate during their hospital stay), and in the postoperative surgical clinic at the postoperative visit. Patients will be within the general surgery, colorectal, and surgical oncology departments at Boston Medical Center (BMC). The anticipated sample size is 60 participants (30 in the intervention/prehabilitation arm and 30 in the control/usual care arm). Participants in the intervention arm will participate in a mobility and step tracking intervention aimed at improving postoperative outcomes. The control group will follow routine standard of care at BMC for preoperative and postoperative care.

Teleconsultation, or the use of video telecommunications technology to deliver expert recommendations for care remotely, has been used to improve the safety and quality of emergency care for children in hospital-based acute care settings by providing real-time access to remote pediatric physician experts. Whether extending teleconsultation as a patient safety intervention to emergency medical systems (EMS) outside hospitals can similarly benefit sick and injured children in the community is unknown. Advances in mobile technology have made teleconsultation more accessible and affordable for EMS systems. However, this intervention has been underutilized by EMS partially due to the lack of prehospital research supporting its efficacy for pediatric applications. In prior simulation studies, the investigators found high intervention acceptance among key stakeholder groups (pediatric emergency physicians and paramedics), and demonstrated that it was feasible to integrate video communication into prehospital clinical workflows involving critical care delivery in high-risk pediatric scenarios. These initial simulation studies were conducted in a controlled prehospital setting in static ambulances using infant simulator manikins to minimize risk to children and providers. Demonstrating feasibility and acceptability with real children in moving ambulances is the next step to build the necessary evidence base to support future planned prehospital efficacy trials with children. The investigators hypothesize that remote respiratory assessment of children by medical control physicians (expert physicians) using a mobile teleconsultation platform is acceptable to users (physicians and transport providers), and technically feasible in real transports.

The majority of women with perinatal posttraumatic stress disorder (PTSD) do not receive mental health treatment despite the documented associations between PTSD and adverse pregnancy outcomes; this is likely due to workforce shortages, lack of data on the effectiveness of existing evidence-based treatment for PTSD in usual care obstetrics settings, and patient-level barriers to engagement such as stigma. The proposed study is a randomized controlled trial, which will examine the effectiveness of a brief evidence-based treatment for PTSD (i.e., Written Exposure Therapy) during pregnancy and the non-inferiority of delivery of this treatment by community health workers vs. delivery by mental health clinicians.

This study will provide rigorous evaluation of implementing a virtual genome center into community clinical settings without highly specialized resources, thereby offering generalizable insights as to how best to implement genomic medicine at scale and for other age groups. This intervention has great potential to address disparities in genomic medicine among low-income and underrepresented minority (URM) populations and will enhance capacity for providers and health systems to utilize highly specialized genomic techniques in their communities. The goal of this study is to achieve equitable access to state-of-the-art genomic medical care to sick newborns in community centers that predominately care for low-income and racial/ethnic minority populations through the creation of a virtual genome center (VIGOR). VIGOR will provide a venue for physician and family education, genomic expert consultation, reanalysis of unsolved sequencing data, and access to cutting edge therapeutic innovation, thereby facilitating institutionalization of genomic best practices in community settings, and not just highly specialized referral centers.

This phase I/Ia trial finds the best dose and side effects of venetoclax given in combination with ixazomib citrate and dexamethasone in treating patients with light chain amyloidosis that has come back (relapsed) or does not respond to treatment (refractory) and who have an abnormal genetic change [translocation t(11;14)]. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Ixazomib citrate is in a class of medications called proteasome inhibitors. It works by helping to kill cancer cells. Anti-inflammatory drugs such as dexamethasone reduce inflammation by lowering the body's immune response and are used with other drugs in the treatment of some types of cancer. Combination therapy with venetoclax, ixazomib citrate and dexamethasone may be effective in treatment of relapsed or refractory light chain amyloidosis.

Within a research network of Head Start centers in Massachusetts, an efficacy trial of a stepped-care intervention (SCI) to address maternal depression, using intervention components that both prevent depression and help those in major depressive episode (MDE) engage with care, will be conducted. Both the prevention and engagement components of the model have strong, supportive randomized trial evidence for both their efficacy and safety; but they have yet to be synthesized and tested within a coordinated intervention, applicable to a broad population base. Stepped-care interventions are commonly used in mental health service projects, in which the intensity or type of service is calibrated to the severity of illness.

To achieve global goals for the treatment of HIV, many countries are piloting 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, the investigators have little evidence on progress and challenges at the facility level-the number of patients actually participating in DSD models, health outcomes and non-health outcomes, effects on service delivery capacity and clinic efficiency and operations, and costs to providers and patients. Alternative Models of ART Delivery: Optimizing Benefits (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. The first AMBIT protocol, "Gathering Records to Evaluate Antiretroviral Treatment" (GREAT, Zambia Ref. No. 2019-Sep-030), collects and analyzes comprehensive patient medical record data, allowing us to assess the effect of DSD models on patients' clinical outcomes and to evaluate uptake of DSD models at scale. The Sentinel-Zambia study, the second AMBIT protocol, is examining the effect of DSD models on patient and provider satisfaction, service delivery capacity and quality, costs to patients, and other outcomes for which data are not routinely collected in patient-level medical records. The first round of Sentinel-SA was conducted in 2021. The AMBIT 2.0 protocol will allow up to four additional annual rounds of data collection, in 2022-2025. The investigators collected clinic aggregate data, conducted surveys of patients and providers, and observed operations at a selected set of 12 Zambian healthcare facilities and their affiliated DSD models in Round 1. Round 2 (2022) and later rounds will collect the same types of data at 12 facilities in Zambia and will expand the study's research questions to include differentiated models of HIV testing and linkage to care. Results are expected to inform Zambian policy makers and other local and international stakeholders on the actual implications of DSD models for patients, health system operations, and healthcare budgets.

Many countries in sub-Saharan Africa are rapidly scaling up "differentiated service delivery" (DSD) models for HIV treatment to improve the quality of care, increase access, reduce costs, and support the continued expansion and sustainability of antiretroviral therapy (ART) programs. Although there is some published evidence about the health outcomes of patients in DSD models, little is known about their impacts on healthcare providers' job satisfaction, patients' quality of life, costs to providers or patients, or how DSD models affect resource allocation at the facility level. SENTINEL is a multi-year observational study that will collect detailed data about DSD models for ART delivery and related services from 12 healthcare facilities in Malawi, 24 in South Africa, and 12 in Zambia. The first round of SENTINEL included a patient survey, provider survey, provider time-and-motion observations, and facility resource use inventory. A survey of clients testing for HIV and a supplement to the facility resource use component to describe service delivery integration will be added for the second round. The patient survey will ask up to 10 patients enrolled in each DSD model at each study site about their experiences in HIV care and in DSD models, costs incurred seeking treatment, and preferences for HIV service delivery. The provider survey will ask up to 10 providers per site about the impact of DSD models on their positions and clinics. The time-and-motion component will directly observe the time use of a sample of providers implementing DSD models. Finally, the resource utilization component will collect facility-level data about DSD model availability and enrollment and the human and other resources needed to implement them. SENTINEL is planned to include at least four approximately annual rounds of data collection between 2021 and 2025. As national DSD programs for HIV treatment mature, it is important to understand how individual healthcare facilities are interpreting and implementing national guidelines and how healthcare workers and clients are adapting to new models of service delivery. SENTINEL will help policy makers and program managers understand the benefits and costs of differentiated service delivery and improve resource allocation going forward.

The purpose of this clinical trial is to answer the question: can the investigators predict which adults with social anxiety disorder (SAD) will successfully respond to treatment? To answer this question, the investigators plan to recruit 190 adult participants who experience extreme forms of social anxiety to undergo brain imaging before and after 12 weeks of group cognitive behavioral therapy (CBT). Adults in the SAD group who do not respond enough to group CBT may be offered the opportunity to complete an additional 12 weeks of individual CBT while receiving SSRI medication (sertraline, see below) for SAD. Data collected from participants who experience anxiety will be compared to a group of 50 participants with little or no social anxiety, who will serve as a comparison group.
