Filter by:This study is an open-label, dose-escalating Phase 1 investigation of S. flexneri 2a InvaplexAR vaccine. A total of up to 40 subjects will receive one of four S. flexneri 2a InvaplexAR vaccine doses. The vaccine will be administered intranasally (without adjuvant).
The rural healthcare market in much of the developing world is composed largely of informal private providers. These private providers often have little to no certifiable medical training. Recent studies in India using medical vignettes (or hypothetical medical situations) to measure clinical competence and direct observations of doctor-patient interactions to measure clinical practice highlight the poor quality of care that most patients receive—a problem that is clearly relevant beyond India and affects most low-income countries worldwide. For instance: 1. In rural India, standardized patients presenting with chest pain and (on further questioning) radiating pain in the arm are (correctly) diagnosed with a heart attack in less than 25 percent of cases. 2. Across 8 low and middle-income countries, health care providers completed the four necessary vital statistics for new patients in less than 4 percent of interactions: health care providers in the public sectors of many developing countries routinely spend less than 1 minute per patient. To address these deplorably low standards in both medical knowledge and practice, the Liver Foundation in Kolkata has been working with private rural health care providers through capacity building activities to improve quality in the private sector. The program consists of multiple-week training to private rural health care providers on the basis of a well-developed curriculum in the district of Birbhum, West Bengal. This study aims to assess the impact of this training program using a randomized evaluation, in which providers are randomly assigned to the treatment, i.e. the Liver Foundation's training program, or the control, i.e. no such training. As an independent outside evaluation team, we will run a baseline survey for all providers (through a third party data collection agency), monitor the application of and compliance in the Liver Foundation's training intervention, and conduct a final endline study. By comparing the treatment and control groups on a variety of measures developed to capture competence in provider knowledge and practice, we can rigorously assess whether such a training program for informal rural health care providers is an effective means of improving provider medical knowledge and practice in the short run. It is worth noting that this study will not be able to capture long run effects , such as price or location changes, on health care for the rural poor.
This study is a randomized, double-blinded, placebo-controlled, in-patient trial evaluating the prophylactic efficacy of rifaximin against campylobacteriosis following challenge with C. jejuni.
This project will examine the spread of health interventions with a randomized control trial design by introducing public health interventions in 32 villages in the Honduran Department of Lempira. Based on identified public health needs in the region, namely improved drinking water and diet, this study will provide training on the use of chlorine (sodium hypochlorite) for water purification and multivitamins for nutritional supplementation. In some villages, individuals selected for their social connectedness will be trained and given coupons that can be redeemed for either chlorine bleach or multivitamins, and these persons will be asked to spread this information and distribute coupons to four people of their choosing. In other villages, individuals selected at random will receive the same training, materials, and instructions. A second wave of coupon distribution will provide coupons to those who received a coupon from the original "seed" groups so that they may disperse these coupons further out in the social networks. Over the following months, study investigators will look at how knowledge of these health practices, and uptake or and adherence to the practices, spreads throughout the villages. More specifically, the investigators will examine the speed and extent of spreading of these new health practices after introducing them to three different initial "seed" groups: (1) people chosen on the basis of being named as a friend by many people in their village, (2) people chosen based on being named as a friend by a randomly chosen individual, and (3) a group of randomly chosen individuals. It is hypothesized that spread will occur faster and/or to a greater extent when the intervention is started in groups 1 and 2 versus group 3 (control group).
SODISWATER was a health impact assessment study investigating the effect of sunlight to inactivate microbial pathogens in drinking water. This study was carried out by observing whether children younger than 5 years old who drink solar disinfected water were healthier than those who did not. Health was measured by how often the children had diarrhoea or dysentery. Caregivers for the participants were given plastic bottles to place in the sun, water samples were then collected from these plastic bottles to be analyzed. They were also requested to fill in diarrhea diaries. TESTABLE RESEARCH HYPOTHESES: Health Impact Assessment: Children who use solar disinfected water will have: (a) lower morbidity due to non-bloody diarrhoea and bloody diarrhoea (c) increased growth rates (d) lower mortality (e) increased family productivity (f) decreased care-giver burden (g) increased school attendance
The purpose of this study is to prove the non-inferiority of Rifamycin SV-MMX® versus Ciprofloxacin for the treatment of adults with traveller's diarrhoea.
The purpose of this study is to determine whether Rifamycin SV MMX is a safe and effective treatment for Traveler's Diarrhea.
The overall goal of this study is to investigate whether the modulatory effects of probiotics, which are used as food supplements (Lactobacillus GG marketed as Culturelle or yoghurt) in the gastrointestinal tract promote restoration of intestinal function and enhance the specific immune response in children with cryptosporidial or rotaviral infections in South India. Rotavirus and Cryptosporidium spp. are the most important viral and parasitic causes of gastroenteritis in children in south India. Both infections can lead to severe dehydrating gastroenteritis in young children and have no specific treatment. Repeated episodes of diarrhea can result in long term deleterious effects on nutritional status, possibly due to intestinal damage. Most episodes of infectious gastroenteritis resolve without specific therapy, the mainstay of treatment being rehydration. However, oral rehydration remains under-utilized, in part due to the lack of effect on frequency of bowel movements and duration of illness. Due to the interest in simple, safe and effective measures to ameliorate the long-term effects of diarrheal illness, there is a growing appreciation for the potential of certain microorganisms to offer direct benefits to the health of a host. Probiotics are known to beneficially modulate several host functions, the most important of which are immune responses and intestinal barrier integrity. The investigators propose to build on the investigators previous collaborative efforts to conduct pilot studies to provide a mechanistic understanding of the effect of probiotic supplementation in children with rotaviral and cryptosporidial diarrhea. Based on the established efficacy of LGG for the treatment of a variety of diarrheal diseases and the documented modulation of immune responses and strengthening of intestinal epithelial barrier function by probiotics, the investigators propose to conduct a Phase I/II double-blind randomized placebo controlled clinical trial to assess the preliminary efficacy and safety of LGG vs. placebo in the resolution of symptoms and restoration of intestinal function in children with either rotaviral or cryptosporidial diarrhea and no other detected enteric infection. Promising results in this Phase I/II study will provide preliminary data to power a future randomized trial on these critical outcomes following rotaviral or cryptosporidial infection.
This study is an inpatient trial to determine the safety, immunogenicity and efficacy of the WRSS1 candidate vaccine in healthy Thai adult volunteers.
