Three tubular anaerobic digestion (AD) systems were installed in Haiti to treat black water (toilet-based wastewater), including a three cell 36m(3) clinic digester (CD), a two cell 2m(3) hotel digester (HD), and a three-cell 3m(3) farm digester (FD) for worker use. During digestion, total coliforms were reduced by 99.1%, E. coli by 98.5%, and chemical oxygen demand (COD) by 93.6%. Nutrients in the effluent averaged 99.4mg/L NH4(+) and 10.6mg/L PO4(2-), producing an effective organic fertilizer. Average biogas production in CD was 108L/d, with 65...

Parallel global rise in pit-latrine sanitation and groundwater-supply provision is of concern due to the frequent spatial proximity of these activities. Study of such an area in Malawi has allowed understanding of risks posed to groundwater from the recent implementation of a typical developing-country pit-latrine sanitation policy to be gained. This has assisted the development of a risk-assessment framework approach pragmatic to regulatory-practitioner management of this issue. The framework involves water-supply and pit-latrine mapping, monitoring of key groundwater contamination indicators and surveys of possible environmental site-condition factors and culminates in an integrated statistical evaluation of these datasets to identify the significant factors controlling risks posed...

Humans can be exposed to pathogens from poorly managed animal feces, particularly in communities where animals live in proximity to humans. This systematic review of peer-reviewed and grey literature examines the human health impacts of exposure to poorly managed animal feces transmitted via water, sanitation, and hygiene (WASH)-related pathways in low- and middle-income countries where household livestock, small-scale animal operations, and free-roaming animals are common. We identify routes of contamination by animal feces, control measures to reduce human exposure, and propose research priorities for further inquiry...

Stunting is associated with impaired cognitive and motor function. The effect of an education intervention including nutrition, stimulation, sanitation, and hygiene on child growth and cognitive/language/motor development, delivered to impoverished mothers in Uganda, was assessed. In a community-based, open cluster-randomized trial, 511 mother/children dyads aged 6-8 months were enrolled to an intervention (n = 263) or control (n = 248) group. The primary outcome was change in length-for-age z-score at age 20-24 months...

The chance discovery of a 1.5-3.5 years old mummified girl presents a unique opportunity to further our understanding of health and disease among children in 19th Century San Francisco. This study focuses on carbon and nitrogen stable isotope signatures in serial samples of hair that cover the last 14 months of her life. Results suggest an initial omnivorous diet with little input from marine resources or C4 plants. Around six months before death δ15N starts a steady increase, with a noticeable acceleration just two months before she died...

The problems posed by fecal sludge (FS) are multidimensional because most cities rapidly urbanize, which results in the increase in population, urban settlement, and waste generation. Issues concerning health and waste treatment have continued to create alarming situations. These issues had indeed interfered with the proper steps in managing FS, which contaminates the environment. FS can be used in agriculture as fertilizer because it is an excellent source of nutrients. The recent decline in crop production due to loss of soil organic component, erosion, and nutrient runoff has generated interest in the recycling of FS into soil nutrients through stabilization and composting...

BACKGROUND: Participatory health initiatives ideally support progressive social change and stronger collective agency for marginalized groups. However, this empowering potential is often limited by inequalities within communities and between communities and outside actors (i.e. government officials, policymakers). We examined how the participatory initiative of Village Health, Sanitation, and Nutrition Committees (VHSNCs) can enable and hinder the renegotiation of power in rural north India...

Access to safe sanitation services is fundamental for healthy and productive lives, but in rural Burkina Faso only around 7% of the population uses improved sanitation. Ecological sanitation (ecosan) systems that allow safe agricultural reuse of nutrients in human waste have been promoted in these areas, as a way to meet sanitation needs while contributing to food security. However, little is known about the success of these interventions in terms of both sustained use of the toilet and safe excreta reuse practices...

Enzootic pneumonia (EP) in pigs caused by Mycoplasma (M.) hyopneumoniae has successfully been combatted in Switzerland. A control program was fully implemented in 2004 which is based on total depopulation strategies of affected fattening farms as well as partial depopulation on breeding farms. Thereby, the number of cases has dropped drastically from more than 200 in 2003 to two cases in 2013. Currently monitoring is done based on clinical observation and subsequent diagnostic of coughing pigs. Moreover, in case of more than 10% gross pathological lesions per slaughter batch laboratory confirmation for EP is compulsory...

Developing country governments and aid agencies face difficult decisions on how best to allocate their finite resources. Investments in many different sectors -including education, water and sanitation, transportation, and health- can all reap social and economic benefits. This report focuses specifically on the health sector. It presents compelling evidence of the value of scaling-up health investments. The economic case for increasing these investments in health has never been stronger. Having made progress in reducing maternal and child mortality, and deaths from infectious diseases, it is essential that policymakers do not become complacent...

Freud's repression of Judaism and its cultural markers from the published "Rat Man" case history has been noted but never satisfactorily explained. This elision can be interpreted using Freud's suggestion that the paradigmatic "rat" represents (among other things) a circumcised penis marking an intergenerational, covenantal exchange. When read against the case study as originally published, Freud's process notes for the Rat Man's treatment (the only set of such notes on a published case that Freud didn't destroy) suggest that Freud chose to sanitize the published version of explicitly Jewish content, thus repeating a pattern of absence as a marker of debt...

Human noroviruses (hNoVs) are a known public health concern associated with the consumption of leafy green vegetables. While a number of studies have investigated pathogen reduction on the surfaces of leafy greens during the postharvest washing process, there remains a paucity of data on the level of treatment needed to inactivate viruses in the wash water, which is critical for preventing cross-contamination. The objective of this study was to quantify the susceptibility of hNoV GI, hNoV GII, murine norovirus (MNV), and bacteriophage MS2 to free chlorine in whole leaf, chopped romaine, and shredded iceberg lettuce industrial leafy green wash waters, each sampled three times over a 4-month period...
