Polymer vesicles, or polymersomes, are being widely explored as synthetic analogs of lipid vesicles based on their stability, robustness, barrier properties, chemical versatility and tunable physical characteristics. Typical methods used to prepare giant-sized (> 4 µm) vesicles, however, are both time and labor intensive, yielding low numbers of intact polymersomes. Here, we present for the fir...

Diarrhoea complicates over half of admissions to hospital with Background severe acute malnutrition (SAM). World Health Organization (WHO) guidelines for the management of dehydration recommend the use of oral rehydration with ReSoMal (an oral rehydration solution (ORS) for SAM), which has lower sodium (45mmols/l) and higher potassium (40mmols/l) content than old WHO ORS. The composition of ReS...

CONTEXT In May 2002, the World Health Organization and the United Nations Children's Fund recommended that the formulation of oral rehydration solution (ORS) for treatment of patients with diarrhea be changed to one with a reduced osmolarity and that safety of the new formulation, particularly development of symptomatic hyponatremia, be monitored. OBJECTIVE To measure the rates of symptomatic...

Diarrhoea continues to be a leading cause of morbidity and mortality around the world, resulting in an estimated 1.5 billion episodes and 1.5 million to 2.2 million deaths annually among children aged less than five years (1,2). Oral rehydration therapy (ORT) effectively treats mild-to-moderate dehydration due to diarrhoea and, for the past three decades, has saved millions of lives, mostly in ...

The World Health Organization and the United Nations Children's Fund recommend using a new oral rehydration solution (ORS) plus zinc supplementation for 10-14 days for the treatment of diarrhoea in children aged less than five years. The Social Marketing Plus for Diarrhoeal Disease Control: Point of Use Water Disinfection and Zinc Treatment (POUZN) project in Nepal was one of the first zinc-pro...

Acute gastroenteritis is a very common disease. It causes significant mortality in developing countries and significant economic burden to developed countries. Viruses are responsible for approximately 70% of episodes of acute gastroenteritis in children and rotavirus is one of the best studied of these viruses. Oral rehydration therapy is as effective as intravenous therapy in treating mild to...

Oral rehydration therapy, (also ORT, oral rehydration salts or solutions (ORS), oral electrolyte), is a simple, cheap, and effective treatment for dehydration associated with diarrhea, particularly gastroenteritis, such as that caused by cholera or rotavirus. ORT consists of a solution of salts and sugars which is administered orally. It is used around the world, but is most important in the de...

Background: Diarrhoea complicates over half of admissions to hospital with severe acute malnutrition (SAM). World Health Organization (WHO) guidelines for the management of dehydration recommend the use of oral rehydration with ReSoMal (an oral rehydration solution (ORS) for SAM), which has lower sodium (45mmols/l) and higher potassium (40mmols/l) content than old WHO ORS. The composition of Re...

Diarrheal disease causes ∼1.34 million deaths per year among children under 5 years of age globally. We conducted a Health Care Utilization and Attitudes Survey of 1,012 primary caregivers of children aged 0-11, 12-23, and 24-59 months randomly selected from a Demographic Surveillance population in rural Gambia. Point prevalence of diarrhea was 7.7% (95% confidence interval [CI] = 6.1-9.8); 23....

BACKGROUND Cholera is endemic in Malawi with seasonal outbreaks during the wet season. People living around Lake Chilwa rely on the lake for their water supply. From May 2009 to May 2010, a cholera outbreak occurred in fishing communities around Lake Chilwa. This paper describes the outbreak response and lessons learned for prevention and management of future outbreaks. METHODS Starting in Ja...
