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.

Country update meeting to share lessons, explore opportunities and overcome challenges to scale up: 8-10 June 2010
Background: Indian adolescents are presumably exposed to a range of potentially traumatizing and negative life events. However, the knowledge on this area is relatively sparse. The present study aims to investigate the prevalence of exposure to potentially traumatizing and negative life events and t...he occurrence of Posttraumatic Stress Disorder (PTSD) among a specific sample of Indian adolescents.

Singing to the Lions is a free training package (facilitator’s guide, supplement and video) by CRS, that is designed to help children and youth lessen the impact of violence and abuse in their lives. The main component is a three-day workshop where participants learn skills that can help them tran...sform their lives and no longer feel dominated by fear. Although the workshop is aimed at young people and includes games, art and songs, it can also be used to help adults take action on aspects of their lives that cause fear and, in so doing, become better parents and caregivers.

A Report on the Application of the HIV Stigma index in the Western highlands and Chimbu provinces
Community health workers (CHWs) enable marginalised communities, often experiencing structural poverty, to access healthcare. Trust, important in all patient–provider relationships, is difficult to build in such
communities, particularly when stigma associated with HIV/AIDS, tuberculosis and now ...COVID-19, is widespread.
CHWs, responsible for bringing people back into care, must repair trust. In South Africa, where a national CHW programme is being rolled out, marginalised communities have high levels of unemployment, domestic violence and injury. In this complex social environment, we explored CHW workplace trust, interpersonal trust between the patient and CHW, and the institutional trust patients place in the health system

The first autochthonous case of chikungunya virus (CHIKV) infection in Brazil was in September 2014 in the State of Amapá, and from there it rapidly spread across the country. The present study was conducted in 2016 in the st...ate of Rio Grande do Norte, and the aims were to describe the epidemiological and the clinical aspects of the CHIKV outbreak.

In the Indian state of Bihar, visceral leishmaniasis (VL) is a major public health issue that has been aggravated by the rising incidence of new Human immunodeficiency virus (HIV) infections. In endemic areas, the risk of VL infections in patients living with HIV (PLHIV) is higher. It is important t...o investigate the disease-related knowledge, attitude, and practices (KAP) of PLHIV in Bihar in order to monitor HIV/VL co-infection. Adequate knowledge, a positive attitude, and good practices for VL control are essential to stamp out the disease. This study investigated the KAP towards VL in HIV patients attending antiretroviral therapy (ART) clinic at ICMR-RMRIMS, Patna.

Chronic respiratory diseases, such as asthma and
chronic obstructive pulmonary disease, kill more than
four million people every year and affect hundreds
of millions more. These diseases erode the health
and well-being of the patients and have a negative
impact on families and societies. Women ...and
children are particularly vulnerable, especially those
in low and middle income countries, where they are
exposed on a daily basis to indoor air pollution from
solid fuels for cooking and heating. In high income
countries, tobacco is the most important risk factor
for chronic respiratory diseases, and in some of
these countries, tobacco use among women and
young people is still increasing.

This study of Adolescent Boys and Young Men highlights the importance of engaging adolescent boys and young men in sexual and reproductive health and rights (srhr) and gender equality. This paper establishes a conceptual framework for engaging adolescent boys and young men. It reviews current resea...rch on boys’ and young men’s specific risks and realities in relation to their general health status, violence, sexuality and sexual and reproductive health, media violence, sexual exploitation, and other vulnerabilities.

Weaknesses in care programmes providing anti‐retroviral therapy (ART) persist and are often instigated by late HIV diagnosis and poor linkage to care. We investigated the potential for a home‐based counselling and testin...g (HBCT) campaign to be improved through the optimal timing and enhancement of testing rounds to generate greater health outcomes at minimum cost.
Countries implementing HBCT can reduce costs by optimally timing rounds and generate greater health outcomes through improving linkage, coverage, and retention. Tailoring HBCT campaigns to individual settings can enhance patient outcomes for minimal cost.
