Increased comorbidities such as cardiovascular disease (CVD), are emerging problems in HIV infection but the mechanisms are unclear. Understanding how antiretrovirals can minimize morbidity in treated HIV infection is a research priority. Nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) are included in all HIV treatment regimens. Tenofovir (TFV) disoproxil fumarate (TDF) has been associated with an increased risk of nephrotoxicity and bone disease compared with other NRTIs. Tenofovir alafenamide (TAF) is an oral prodrug of TFV, but is more stable in plasma as compared with TDF and lower plasma levels of TFV are thought to lead to the favorable safety profile of TAF. Mitochondrial dysfunction has a key role in HIV pathogenesis and may be the common denominator that drives pathogenesis of several comorbidities. Despite the better safety profile of newer (such as TDF) compared to older NRTIs, there are concerns for the potential for longer term toxicity of NRTIs since the exact cellular effects of NRTIs remain unclear. It is unknown whether a four-fold increase in intracellular drug levels seen in peripheral blood mononuclear cells (PBMCs) with TAF may increase toxicity in mitochondria. Better understanding of these effects could provide insights into mechanisms of HIV pathogenesis and selection of NRTIs that improve morbidity in chronic HIV infection. Hypothesis: Despite higher intracellular levels, TAF has minimal mitochondrial toxicity compared to TDF in vivo. This research will explore the relative mitochondrial toxicity of newer NRTIs (TAF, TDF) as a possible mechanism for differential NTRI-related toxicities. These data will allow selection of NRTIs that may improve morbidity in chronic treated HIV infection. Towards this aim, the investigators will use a robust experimental approach to study NRTI-related mitochondrial dysfunction using novel methods, human cell lines and PBMC. Our specific aims are: Aim 1: To evaluate the relative in vitro effects of TAF and TDF compared to an older NRTI (ddC) on 5 independent measures of mitochondrial function in the human cell line HepG2 and PBMC. Aim 2: To explore in vivo whether there is increased mitochondrial dysfunction with the use of TAF vs. TDF in chronic treated HIV infection. The investigators anticipate that the proposed experimental approach will set the basis for future large scale studies to directly compare subtle potential mitochondrial toxicities of newer NRTIs in large HIV cohorts.
This project aims to reveal the potential sensorimotor reorganization of sensory input in low back pain patients and its association with different motor control strategies in LBP.
National mandates for increasing accountability in behavioral healthcare have created an urgent need for effective quality assurance (QA) procedures featuring pragmatic measures of treatment implementation quality in usual care (UC). The most practical method for assessing treatment quality in UC is therapist self-report; unfortunately, therapist-report measures of fidelity to evidence-based practices (EBPs) have demonstrated weak validity to date. This study addresses this need for effective QA procedures by first developing treatment quality assurance procedures designed to increase the adoption and quality of empirically supported family-based services (FBS) for adolescent substance use (ASU) in usual care, and then testing two system-level implementation strategies for installing the new quality procedures in ASU treatment sites. FBS have achieved the strongest evidence base for treating ASU and are a prime candidate for upgrading the quality of ASU services in various systems of care. FBS comprise both family participation in services, the systemic parameters wherein family members are included in assessment and treatment activities; and family therapy techniques, the specific interventions that clinicians use to directly target family members and family functioning for change. For FBS to fulfill their potential to enhance ASU treatment systems, FBS implementation must be supported by effective quality assurance procedures designed to ensure that FBS are delivered with fidelity. The proposed study will leverage a strong research-government partnership between the applicant organization and the New York single-state agency for SU services. The study will first develop innovative quality procedures (Aim 1) that use existing FBS quality metrics to promote high-fidelity FBS: Measurement Training and Feedback System for Implementation (MTFS-I), a pragmatic evidence-based method for increasing FBS quality by providing monthly feedback on therapist-reported FBS delivery along with brief online FBS training modules. The study will then experimentally compare two system-level implementation strategies designed to foster MTFS-I utilization in usual care for ASU. Core Training Only will contain two 3-hour training sessions: Mapping existing FBS and identifying site goals for FBS improvement; and Installing and sustaining the MTFS-I. Core + Facilitation is an additive strategy that will begin with the Core Training sessions and then continue with monthly facilitation meetings for one year to promote MTFS-I use and progress toward FBS improvement. The study will feature a three-group cluster randomized trial testing Core Training Only versus Core + Facilitation versus no-intervention Control in 9 ASU clinics across New York State. MTFS-I utilization data will be collected from Core Training and Core + Facilitation sites for one-year follow-up (after initial Core Training); FBS quality data on family participation and family therapy technique use will be collected from all sites over one-year follow-up; observational coding methods will verify therapist reports of FBS quality; and client outcome data for all sites will be retrieved from administrative data warehouses over one-year baseline and one-year follow-up. These data will enable between-condition comparisons of FBS delivery (Aim 2: MTFS-I utilization, family participation, family therapy technique use) and client outcomes (Aim 3: therapeutic goal achievement, substance use change). If study aims are achieved, investigators would be positioned to mount a fully powered RCT to test the effectiveness of these FBS quality improvement procedures at scale.
This study evaluates the addition of a structured nurse led patient management programme to standard of care in gout patients. Half of the patient will receive the nurse led programme in addition to standard of care and the other half will receive standard of care only.
A randomized controlled, parallel group, superiority, open-label, single-institution, Phase 3 interventional clinical trial to evaluate clinical outcomes in obese gravidas undergoing elective cesarean delivery whose wounds were dressed with the PICO Negative Pressure Wound Therapy (NPWT) versus the standard dressing. We hypothesize that the PICO NPWT will reduce the incidence of surgical site occurrences and interventions and postoperative readmissions in obese women. The study will compare surgical site occurrences and surgical incision intervention incidence within 42 +/- 10 days post cesarean delivery in obese women who have the current standard-of-care dressing versus the PICO NPWT.
The aims are to compare Direct His Bundle Pacing (DHBP) with biventricular pacing (BiV) in terms of electrical resynchronization using electrocardiographic imaging (ECGI) and also in terms of acute hemodynamical effect using finger plethysmography and conduction velocimetry. The study will be a randomized crossover design with acute measurements.
This randomized controlled trial will evaluate a yoga intervention for individuals who experience persistent pain following oncology surgery. The integrated yoga program will involve postures, breathing exercises, and concentration practices. Data will be collected at several time points (pre-, mid-, and post-intervention) for both the intervention and wait-list control conditions. The data will be analysed using linear mixed effects growth models. Results will be written up in manuscript format, published in a peer review journal, and disseminated at scientific research conferences.
Well-child care is the primary source of preventative health care for children. These visits provide an opportunity for physicians to assess an infant's biomedical health, development, and behavior, as well as help ensure timely immunizations, reduce the use of acute care services, and assess and family functioning. Yet, disparities in the utilization of pediatric care exist by race, ethnicity and income in the U.S., even despite high rates of overall access to primary care. Incentives have been proposed as one way to increase utilization of preventative care for mothers and children. Diapering is another important form of preventative health care that can be particularly difficult for low-income parents due the cost of diapers, which is $70-80 per child per month, or approximately $960 per year, on average. And government programs, such as Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), Supplemental Nutrition Assistance Program (SNAP), and Temporary Assistance for Needy Families (TANF), either cannot be used to purchase diapers, or do not provide enough assistance to cover the cost of diapers and other basic needs. A family's inability to provide an adequate supply of diapers for their child is called diaper need. Nationwide, one in three families with young children report experiencing diaper need, which was found to be significantly associated with maternal stress and depression, which in turn, can have a detrimental impact on a family's health and economic success. The primary goal of this study is to conduct a randomized controlled trial of a diaper provision intervention designed to increase utilization of, and adherence to, well-child visits and reduce diaper need among low-resourced families in New Haven, CT.
The ability to find one's way in the world is known as wayfinding. Many older adults who live in senior communities, such as independent living and assisted living residences, find wayfinding very challenging. Often times, these communities are not designed in a way that helps people find their way very easily. When people cannot find their way, they can get lost, be dependent upon others for getting out and about, or even be afraid to leave their rooms. The purpose of this study is to find out if distinctive signs and decorative elements, along with a special type of education called Spaced-Retrieval education, help residents in these communities find their way more effectively. Twelve senior communities will be assigned by chance to one of three conditions, including: 1) control - no change (the community stays the same); 2) signs and decorative elements enhanced; and 3) signs, decorative elements, and special education added. After agreeing to be in the study, the participants will be asked to find their way to certain places in their community four times over a year. Some people will be asked to participate in educational sessions on wayfinding. In addition, some people will be asked to wear a location tracker, (like a fitness tracker), for four weeks during the year. How well people find their way, along with how much they travel about within the communities, will be compared between the three groups. It is hypothesized that those in the communities with special signs and decorative elements will find their way more effectively than those in the control communities. It is also hypothesized that participants in the communities with the special education intervention will find their way better than those without the education. Finally, it is hypothesized that participants in the communities with signs and cues and education will travel about further distances than those in the control communities. The results of the study can help people who have a tendency to get lost find their way more effectively in their community, and this could result in more independence.
The proposed project will examine a promising brief therapy for PTSD for use in VHA Primary Care and its impact on functional outcomes. This intervention will provide an alternative point of access to effective PTSD treatment and improved function that does not require referral to specialty mental health and accomplishes improved function in a short-term, brief protocol. Many Veterans prefer to receive mental health care, including PTSD service in primary care. The current protocol would allow them to access effective therapy options in addition to the medication management that is currently the standard of care for PTSD in primary care. In addition, this brief protocol may reduce the number of specialty mental health referrals as many Veterans may not require additional PTSD specific treatment after completion. Thus, if effective, this protocol will greatly increase Veteran treatment choice and improve functional outcomes and access while also increasing efficiency of allocation of specialty PTSD services.
