Introduction Maternal and neonatal mortality continue to be to be prominent public health issues in sub Saharan Africa including Ghana, with slow progress made towards attainment of Millennium Development Goals (MDG) 4 & 5. Studies have identified poor quality of maternal and child healthcare as a major challenge to the prevention of neonatal and maternal deaths. Effective interventions are required to make significant inroads in these areas. Objective To evaluate the effect of a SMS text messaging intervention to support clinical decision making by frontline health care professionals on neonatal and maternal mortality. Methods We propose to conduct a randomized controlled trial in the Eastern region of Ghana, involving 8 intervention and 8 control districts. The intervention consists of text messaging of standard protocols for maternal and neonatal care to front line health care providers in the region. A total of 17,040 pregnant women who are receiving care (including antenatal, delivery and post-natal) at any of the hospitals in the selected districts in the region will be monitored through monthly aggregate data on outcome measures such as neonatal and maternal deaths from eclampsia, postpartum haemorrhage, puerperal sepsis, birth asphyxia, low birth weight and neonatal sepsis. Cord sepsis will also be included as neonatal sepsis for this study. Also, a quality of care assessment in four sampled districts to measure adherence to the safe motherhood protocol will be conducted. Stata software package.55 and MLwiN software version 2.2456 will be employed in data analysis. Descriptive analysis will be carried out to explore baseline characteristics of study groups while logistic regression will be applied to evaluate the effect of the intervention. A two-tailed statistical significant level of 0.05 will be used. Expected outcome We hypothesize that the intervention will improve both maternal and neonatal service delivery and health outcomes in the intervention areas.
According to the French Biomedicine Agency annual report on retrieval activities and transplants, 1,164 liver transplants were performed in 2011 and 1,161 in 2012. If the amount of brain death donors and retrieved liver grafts appears relatively stable, it remains clearly insufficient compared to the increasing number of patients on the waiting list for liver transplantation (2,462 in 2011). The median time on the waiting list before liver transplantation which was established from the cohort of patients registered between 2007 and 2011 (excluding patients registered for emergency transplantation and for living related-donor transplantation) increased significantly from 4.4 months between 2007 and 2009 to 6.6 months between 2010 and 2011. In order to compensate for the lack of liver grafts, donors acceptance criteria were broadened. For example, alternative transplantation lists were created with liver grafts coming from so-called "marginal" donors. However, despite these efforts, livers were retrieved on only two out of three brain death donors, i.e. in 1,572 and 1,589 organ donors in 2011 and 2012, respectively. This is unfortunately not enough to meet the increasing needs in liver grafts and a growing number of patients wait each year for transplant. Strategic lines of improvement were defined in order to meet the "2012-2016 transplant perspective" which targets 5,700 transplants carried out in 2015 (+5% every year, all transplants included, with 5,023 transplants in 2012). According to the last consensus conference on liver transplantation of the HAS (French High Authority of Health) the assessment of the degree of macrovacuolar and microvacuolar steatosis determines the possibility to retrieve the graft or not. Liver steatosis consists in an accumulation of fatty droplets in hepatocytes. Its prevalence is high, ranging from 16% to 31% in the general population, and increases up to 46% in heavy drinkers and to 50-80% in the obese population. Steatosis results mostly from alcohol consumption and from metabolic syndrome (obesity, type 2 diabetes, hypertriglyceridemia) called non-alcoholic fatty liver disease (NAFLD), and is more rarely secondary to viral hepatitis or exposure to certain medications. NAFLD involves up to 30% of the population in Western countries and its prevalence is increasing. NAFLD may lead to asymptomatic steatosis, but also to steatohepatitis or advanced fibrosis including cirrhosis and its complications Accordingly, the improvement of liver grafts selection based on objective quantitative criteria which takes into account the degree of liver steatosis appears crucial to increase the number of hepatic transplants.
Head and neck squamous cell carcinomas (HNSCCs) are mainly caused by tobacco, alcohol consumption and betel nut chewing and the sixth most common cancer in the world. Despite significant advances in the treatment modalities involving surgery, radiotherapy, and concomitant chemoradiotherapy, the 5-year survival rate remained below 50% for the past 30 years. The worse prognosis of these cancers must certainly be linked to the fact that HNSCCs strongly influence the host immune system. During this process, mesenchymal tumor-like cells are highly mobile and enter quickly adjacent structure (intravasation), from where they travel through lymphatic and blood vessels as circulating tumor cells (CTC), which are single cells with malignant potential detected in the peripheral bloodstream and essential for establishing metastasis. Programmed death 1 (PD-1) and its ligand (PD-L1) play pivotal roles in regulating host immune responses. Substantial evidence has demonstrated that PD-L1 can deliver an inhibitory signal to PD-1 expressing T cells, leading to suppression of the immune response by inducing apoptosis, energy, unresponsiveness and functional exhaustion of T cells. However, the inhibitory effects of this pathway on the function of cytotoxic T lymphocytes, the main effector cells in HNSCC patients, are not well defined. In this study aims to solve two main problems: one is to improve and try to optimize current protocols of CTC isolations based on the investigator previous work, which is one of most challenging problems in CTC field to date; the other is to understand the status of immune system in HNSCC patients, especially focusing on PD-1-PD-L1 pathway and its expressions. After series basic experiments of immune cell analysis and conditional adjustment of CTC isolation protocols, the investigator are willing to isolate CTCs and immune cells at a single blood drawing at the same time. A prospective trial will be conducted to elucidate the roles of PD-1 expression lymphocytes and CTC numbers on the clinical outcomes of HNSCC patients.
Children hospitalized with severe illness in sub-Saharan Africa are at high risk of morbidity and mortality following discharge from hospital. These children represent an accessible high-risk population in which targeted interventions to prevent morbidity and mortality could have dramatic impact. A large cluster randomized trial of azithromycin delivered in a mass drug administration program within trachoma endemic areas in sub-Saharan Africa demonstrated an almost 50% mortality benefit in children 1-9 years of age in treated communities. However, mass drug administration of azithromycin leads to the rapid emergence of macrolide resistance within treated communities and is expensive. The targeted delivery of azithromycin to children at hospital discharge may be a novel and practical intervention to maximize benefit while minimizing risk of antibiotic resistance. This is a randomized, double-blind, placebo-controlled trial to determine the efficacy of azithromycin provided at discharge, compared to placebo, in reducing mortality and re-hospitalization rates in children age 1-59 months in Kenya. The study will also investigate potential mechanisms by which azithromycin may reduce morbidity and mortality in this population and will assess the emergence of antibiotic resistance among treated individuals and their primary caregivers. A cost-effectiveness analysis of the intervention will also be conducted.
This study will explore the feasibility of initiating a uterine transplant program at UNMC. Using the procedural templates established by a successful Swedish team, the investigators will identify emotionally and socially stable females of reproductive age with intact ovaries who are unable to gestate a child due to congenital or acquired uterine factor infertility (UFI). Women will be 21 to 35 years of age upon entry into the protocol, with normal ovarian reserve and otherwise healthy for pregnancy. After careful screening, participants will undergo egg harvest, in-vitro fertilization, and embryo cryopreservation using standard methods. Women who successfully complete in vitro fertilization and cryopreservation of at least six embryos will be eligible to receive implantation of a deceased donor uterus. After a period of observation to ensure normal menstrual cycling and graft viability, embryo implantation will be undertaken. Gestations will be carefully monitored by our high-risk pregnancy specialists. Medical research interventions include uterine harvest from a deceased donor, surgical implantation of the organ utilizing standard transplant techniques, careful post-transplant follow-up including immune suppression therapy tailored to minimize fetal compromise, and careful management of pregnancy. After childbearing is complete (at most two gestations), the donor uterus will be removed. In addition, open-ended interviews and written surveys will be conducted to elicit ethical and psychosocial concerns arising from the experience of subjects and their families, health care providers, and the wider community. The investigators intent is to monitor outcomes lifelong for transplant recipients and live-born infants.
Cohort study aimed at evaluating the incidence of left ventricular (LV) dysfunction after myocardial infraction (MI) and assessing the prognostic utility of change in ejection fraction (EF) over the initial 12 months after MI.
Heart failure is a chronic and frequently terminal illness associated with poor quality of life and high burden of morbidity, re-hospitalization, and cost. Accordingly, recent guideline updates have highlighted the need for improved focus on end-of-life and palliative care of advanced heart failure patients, in whom symptom burden can be high and treatment options are often limited. The aims of this study are to evaluate the feasibility of implementing a semi-structured, outpatient, nurse practitioner-led, educational supportive care intervention concerning multiple domains of end-of-life care not often included in regular, outpatient clinic visits.
The overarching goal of this research program is to improve the quality of end-of-life care provided to Veterans dying in VA Medical Centers (VAMCs), by transferring the best practices of home hospice and palliative care for the last days and hours of life into the inpatient setting. This trial will examine two methods of delivering a Comfort Care Education Intervention utilizing the established infrastructure of VA Palliative Care Consult Teams (PCCT): a Basic Implementation Approach using a teleconference to review educational materials and activate PCCTs to educate other providers, and an Enhanced Implementation Approach utilizing in-person, train-the-"champion" workshops to prepare PCCT members to be leaders and trainers at their home sites. Findings will provide a robust evaluation of the implementation process, and will be used to refine the Comfort Care Education Intervention and implementation strategies in preparation for nationwide dissemination of best practices for end-of-life care within the VA Healthcare System.
