Background: The human helminth infections include ascariasis, trichuriasis, hookworm infections, schistosomiasis, lymphatic filariasis (LF) and onchocerciasis. It is estimated that almost 2 billion people worldwide are infected with helminths. Whilst the WHO treatment guidelines for helminth infecti...ons are mostly aimed at controlling morbidity, there has been a recent shift with some countries moving towards goals of disease elimination through mass drug administration, especially for LF and onchocerciasis. However, as prevalence is driven lower, treating entire populations may no longer be the most efficient or cost-effective strategy. Instead, it may be beneficial to identify individuals or demographic groups who are persistently infected, often termed as being “predisposed” to infection, and target treatment at them.
Methods: The authors searched Embase, MEDLINE, Global Health, and Web of Science for all English language, humanbased papers investigating predisposition to helminth infections published up to October 31st, 2017. The varying definitions used to describe predisposition, and the statistical tests used to determine its presence, are summarised. Evidence for predisposition is presented, stratified by helminth species, and risk factors for predisposition to infection are identified and discussed.
Results: In total, 43 papers were identified, summarising results from 34 different studies in 23 countries. Consistent evidence of predisposition to infection with certain species of human helminth was identified. Children were regularly found to experience greater predisposition to Ascaris lumbricoides, Schistosoma mansoni and S. haematobium than adults. Females were found to be more predisposed to A. lumbricoides infection than were males. Household clustering of infection was identified for A. lumbricoides, T. trichiura and S. japonicum. Ascaris lumbricoides and T. trichiura also showed evidence of familial predisposition. Whilst strong evidence for predisposition to hookworm infection was identified, findings with regards to which groups were affected were considerably more varied than for other helminth species.
Conclusion: This review has found consistent evidence of predisposition to heavy (and light) infection for certain human helminth species. However, further research is needed to identify reasons for the reported differences between demographic groups. Molecular epidemiological methods associated with whole genome sequencing to determine ‘who infects whom’ may shed more light on the factors generating predisposition.

We developed an integrated vector surveillance (IVS) proposal for cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) in the Americas, based on eco-epidemiological studies conducted by researchers of the Leishmaniasis Research Network of Argentina. For CL, the transmission was explained in ...the framework of the edge effect, the increase of vectors and risk of exposure at ecotones and environmental interfaces, and typified as ephemeral, transient, or permanent edges, supporting a cost-effective IVS strategy for early warning of CL outbreaks through an environmental modification alert network, which includes multiple sources of information and actors. In relation to VL, the earliest colonization sites and spatial distribution were explained by modeling and forecasting the most likely hotspots, persistent in time and space, and modulated by environmental variables. Therefore, for VL, a scalar strategy of critical site selection is proposed from a “city” scale based on secondary sources such as remote sensing for the definition of possible areas to monitor and intervene, a scale of restriction from possible to most likely areas through local knowledge, and a “focal site” scale of trap placement through field observation; in this way, IVS activities are carried out at a few sites of the urban landscape and allow a sustainable program.

This video animation was created for use in West Africa to help dispel myths about how Ebola is spread, and to prevent infection and further spreading of the disease. The story is based around a teenage boy on a hospital cot in Liberia, who speaks to his parents, brother and sister warning them abou...t the disease and telling them how it can be prevented. The story highlights the need for isolation and shows the heartache of the family as they are unable to comfort, touch, or care for the boy who is very ill. His words are words of comfort to those who are separated from their loved ones as they are encouraged to take care of themselves and keep away from those who are ill.
The video was created by Chocolate Moose Media, an organisation specialising in the use of film and animation for behaviour change, and mobile-health-education innovator iHeed, in collaboration with United Methodist Communications, who provided partial funding.
The video, which uses only young voices, is being made available in eight versions: Nigerian English and Pidgin, South African English, French (for Ivory Coast and Guinea), Sierra Leone English, and Liberian English and Krio. It can be downloaded in high definition, low definition, and for use on mobile platforms.

There is no question that over the last thirty years environmentaldegradation and the ecological crisis have become in our day and age apredominant sign of the times. In response to this worrisome develop-ment official documents of the Roman Catholic Church, at various lev-els, have sought to addres...s the growing ecological concern from theperspective of Catholic social teaching. Consequently references to ecol-ogy and environmental issues have surfaced in papal encyclicals duringthe last fifteen years generating national and regional responses. In theUnited States, for example, the U.S. Conference of Catholic Bishops hasissued two pastoral statements on environmental issues in 1991 and2001. Significantly, the Catholic Bishops of the Pacific Northwest, rep-resenting Canada and the U.S. have also issued a unique internationalletter focused on a particular ecological region—the Columbia RiverWatershed. What all of these efforts hold in common is the attempt toapply Catholic social teaching to a new and disturbing phenomenon inhuman experience. The result has been an expansion of Catholic socialthought. What was once the “social question” has now become the socialand “ecological question.” This development, the effort to address ecol-ogy and environmental issues as ethical problems, is the focus of thispaper. In particular this paper will link environmental and humanecology with the concept of sustainability, with the intention of propos-ing an interpretation of the common good and a definition of sustain-ability within Catholic social teaching.

The pamphlet "Marijuana" explains the effects and risks of cannabis use. It describes THC, the psychoactive compound in cannabis, which binds to cannabinoid receptors in the brain, causing effects like relaxation, altered perception, and euphoria. Short-term effects include red eyes, hunger, and anx...iety, while long-term effects may involve memory loss, lung problems, and slowed brain development, especially with early and frequent use. It highlights the potential for negative impacts on mental and physical health while noting there are no direct deaths solely from marijuana use. The pamphlet provides links to resources for further information and recovery options.

The OECD's "Alcohol Consumption" indicator measures the annual sales of pure alcohol in liters per person aged 15 and older. This metric helps assess long-term trends in alcohol consumption across countries. It's important to note that the methodology for converting alcoholic beverages to pure alcoh...ol may vary between nations. Additionally, official data typically do not account for tourist consumption or unrecorded alcohol intake, such as homemade or illegally produced alcohol. While this indicator provides insight into overall consumption patterns, it does not capture harmful drinking behaviors like heavy episodic drinking.

The classification of digital health interventions (DHIs) categorizes the different ways in which digital and mobile technologies are being used to support health system needs. Historically, the diverse communities working in digital health—including government stakeholders, technologists, clinic...ians, implementers, network operators, researchers, donors— have lacked a mutually understandable language with which to assess and articulate functionality. A shared and standardized vocabulary was recognized as necessary to identify gaps and duplication, evaluate effectiveness, and facilitate alignment across different digital health implementations. Targeted primarily at public health audiences, this Classification framework aims to promote an accessible and bridging language for health program planners to articulate functionalities of digital health implementations.
