Filter by:Excessive bleeding after cardiopulmonary bypass (CPB) operations remains to be a persistent problem. Antiplatelet therapy (APT) is an integral component of perioperative management in patients undergoing cardiac surgery. The impact of drug induced platelet inhibition on early postoperative bleeding extent and transfusion requirements remains difficult to predict. In addition to, resistance to antiplatelet drugs as well as perioperative increase in platelet reactivity following CPB has been reported but this phenomenon has to be comprehensively investigated. The best point-of-care platelet function test to predict bleeding complications/transfusion requirements remains unclear. In addition to, the best test platelet function test to monitor resistance to antiplatelet therapy and its impact on clinical outcomes remains elusive. The aim of this study is: 1. to compare two point-of-care platelet function analyzers (Multiplate and ROTEM Platelet) in regard to prediction of bleeding complications/trasfusion requirements. 2. to compare two point-of-care platelet function analyzers (Multiplate and ROTEM Platelet) in regard to detection of high "on-treatment" platelet reactivity both pre- and postoperatively.
The purpose of this randomized trial is to clarify the role of enteral nutrition (EN) on the relationship between cardiopulmonary bypass-induced inflammation and insulin resistance by investigating the effects of two different feeding strategies in infants following cardiac surgery. The study's primary objective is to determine if early and higher volume feeding modifies the relationship between the severity of postoperative systemic inflammation and insulin resistance.
The study will examine the quality of two sedation techniques (dexmedetomidine and pentobarbital) used for children aged 3 to 24 months who are undergoing a transthoracic echocardiography (TTE).
In response to Program Announcement (PA)-09-164, "NIH Exploratory/Developmental Research Grant Program (R21) a randomized pilot study testing the efficacy of SWIFT: Social Work Intervention Focused on Transitions among at-risk older adults following hospital discharge to home. This study is drawn from several observations. First, transitions between care settings create elevated risk for poor outcomes and for readmission among older adults leaving the hospital for home largely due to fragmented care and poor communication. Next, while few studies exist that test methods to improve transitions, those available are largely medically focused, using a nurse or advanced practice nurse in their approach. Although evidence exists to support the effectiveness of these models, few have been replicated and none have been integrated into standard health care practice. This may be attributed to several factors including the availability of the needed staff, the lack of existing structures to support these roles, and the costs of implementing these interventions. Finally, a social work driven intervention may provide a replicable mechanism for bridging medical care, addressing psychosocial needs as well as medical needs, and improving linkages with community services while reducing care duplication. This study aimed to test a structured social work transition intervention model to reduce rates of hospital readmission and medical service use while improving patient satisfaction with the care transition process. A randomized pilot study was used to test a social work transitions model designed to improve care provided to frail older adults being discharged from the hospital to return to the community. Eligible patients consenting to participate (n=181) were randomly assigned to either the social work transitions model intervention or usual care. This project was conducted at Huntington Hospital, a 525-bed, nonprofit, community hospital located in Pasadena, California. In an average year, Huntington Hospital has approximately 10,000 older adults discharged from their facility, 44% of who are 80 years old or older. Those randomized to the intervention arm received up to six sessions from the social worker, at least one provided in the home. The social work intervention was designed to overcome common problems following hospital discharge including medication review, discussion and planning around discharge instruction, assistance in scheduling follow up appointments, assessments of psychosocial and other support service needs and provision of linkages to address those needs. Outcomes were measured three and six months following arrival at home, with an interim measure of satisfaction at 10 days following arrival at home, with measures including patient level of depression, pain, physical functioning, self-efficacy with disease management, and medical service use.
One of the most common postoperative complications after open cardiac surgery is fluid accumulation between the pleural membranes or in the pericardial sac. This study investigates the consequence of such fluid accumulations on physical performance, recovery-time, cardiac and respiratory complications, and quality of life. Half of the participants will be followed closely and offered fluid drainage at a low threshold, and half of the participants will follow the current postoperative regimen.
Ancillary Effects of Dexmedetomidine Sedation After Cardiac Surgery
The outcome of this research will be a demonstration that family health history (FHH) risk data can be used efficiently to deliver more effective healthcare in geographically and ethnically diverse clinical care environments. Although FHH is a standard component of the medical interview its widespread adoption is hindered by three major barriers: (1) a dearth of standard collection methods; (2) the absence of health care provider access to complete FHH information; and (3) the need for clinical guidance for the interpretation and use of FHH. In addition, the time constraints of the busy provider and poor integration of FHH with paper medical records or electronic medical records (EMR) impede its widespread use. The investigators hypothesize that patient-driven and electronic collection of FHH for risk stratification will promote more informed decision-making by patients and providers, and improves adherence to risk-stratified preventive care guidelines. The study team will use an implementation sciences approach to integrate an innovative FHH system that collects FHH from patients. Intermountain Healthcare will provide the information technology expertise with EMR design to develop an innovative solution to a storage model standard for FHH data as well as a centralized standards-compliant open clinical decision support (OpenCDS) rule development architecture to analyze FHH and to generate evidence-based, individualized, disease risk, preventive care recommendations for both patients and providers.
Recent advances in genomic techniques are making possible a new wave of genetic discovery in congenital heart disease (CHD). Existing data suggests that CHD occur in Sub-Saharan Africa at frequencies similar to the rest of the world. In this application, we propose to utilize the unique advantages of Sub-Saharan Africa - a combination of the most genetically diverse populations in the world and of diminished environmental background effects (i.e. low prevalence of smoking, alcohol abuse, obesity in comparison to western countries) - to better understand the genetic basis for congenital heart disease. We will couple next generation genomic techniques with more traditional gene discovery methods to investigate CHD in two African countries: Uganda and Nigeria. The inclusion of syndromic and non-syndromic CHD observed in these populations as well as careful phenotyping (including echocardiography) will greatly enhance our potential to provide insight into the genetic architecture of CHD in African populations. To accomplish this, we plan to enroll families, in whom members have congenital heart malformations consistent with an error of early human development in our research protocol. Patients will be enrolled at the Uganda Heart Institute in Kampala, Uganda, and at the Department of Pediatrics, College of Medicine, University of Lagos, Nigeria, with the potential to include other African sites. High throughput genomic studies will be done at the NIH.
Heart failure with preserved ejection fraction (HFpEF) is a major public health problem that has no proven effective treatment. This study assessed the effects of acute nitrite administration on resting and exercise hemodynamics in patients with HFpEF.
