Yemen is currently experiencing, to our knowledge, the largest cholera epidemic in recent history. The first cases were declared in September 2016, and over 1.1 million cases and 2,300 deaths have since been reported1. Here we investigate the phylogenetic relationships, pathogenesis and determinants of antimicrobial resistance by sequencing the genomes of Vibrio cholerae isolates from the epidemic in Yemen and recent isolates from neighbouring regions. These 116 genomic sequences were placed within the phylogenetic context of a global collection of 1,087 isolates of the seventh pandemic V. cholerae serogroups O1 and O139 biotype El Tor2-4. We show that the isolates from Yemen that were collected during the two epidemiological waves of the epidemic1-the first between 28 September 2016 and 23 April 2017 (25,839 suspected cases) and the second beginning on 24 April 2017 (more than 1 million suspected cases)-are V. cholerae serotype Ogawa isolates from a single sublineage of the seventh pandemic V. cholerae O1 El Tor (7PET) lineage. Using genomic approaches, we link the epidemic in Yemen to global radiations of pandemic V. cholerae and show that this sublineage originated from South Asia and that it caused outbreaks in East Africa before appearing in Yemen. Furthermore, we show that the isolates from Yemen are susceptible to several antibiotics that are commonly used to treat cholera and to polymyxin B, resistance to which is used as a marker of the El Tor biotype.

Background: In Myanmar, HIV is concentrated among key populations, yet less than half of the estimated 250,000 men who have sex with men (MSM) and transgender women (TW) report recent HIV testing. As many as 50% of MSM and TW may conceal their same-sex preferences and behaviors, yet little is known about the barriers faced by those who are locally regarded as 'hidden' - that is, MSM who do not disclose same-sex preferences and/or identify as gay. This study explored specific barriers to accessing HIV testing and other prevention services among 'hidden' MSM to inform appropriate models of service delivery.

Methods: In-depth interviews with MSM (n = 12) and TW (n = 13) and focus group discussions (FGD) with MSM and TW community members, leaders and key informants (n = 35) were undertaken in Yangon during June - September 2015. Participants were recruited by word-of-mouth by trained peer data collectors. Responses to questions from semi-structured guides were transcribed and coded using Atlas Ti. Codes were based on key domains in the guides and applied to transcripts to identify and analyze emerging themes.

Results: Fear of stigma and discrimination and the need to meet gender expectations were key reasons for non-disclosure of same-sex preferences and behaviors; this typically manifested as avoidance of other MSM and settings in which sexual identity might be implicated. These concerns influenced preference and interaction with HIV services, with many avoiding MSM-specific services or eschewing HIV testing services entirely. The difficulties of engaging hidden MSM in HIV prevention was strongly corroborated by service providers.

Conclusion: Hidden MSM face multiple barriers to HIV testing and prevention. Strategies cognizant of concerns for anonymity and privacy, such as One-Stop Shop services and online-based health promotion, can discretely provide services appropriate for hidden MSM. Enhanced capacity of peer-service providers and mainstream health staff to identify and respond to the psychosocial challenges reported by hidden MSM in this study may further encourage service engagement. Overarching strategies to strengthen the enabling environment, such as legal reform and LGBTI community mobilisation, can lessen stigma and discrimination and increase hidden MSM's comfort and willingness to discuss same-sex behavior and access appropriate services.

The 2013-2016 epidemic of Ebola virus disease (EVD) that originated in West Africa underscored many of the challenges to conducting clinical research during an ongoing infectious disease epidemic, both in the most affected countries of Guinea, Liberia, and Sierra Leone, as well as in the United States and Europe, where a total of 27 patients with EVD received care in biocontainment units. The Special Pathogens Research Network (SPRN) was established in the United States in November 2016 to provide an organizational structure to leverage the expertise of the 10 Regional Ebola and Other Special Pathogen Treatment Centers (RESPTCs); it was intended to develop and support infrastructure to improve readiness to conduct clinical research in the United States. The network enables the rapid activation and coordination of clinical research in the event of an epidemic and facilitates opportunities for multicenter research when the RESPTCs are actively caring for patients requiring a biocontainment unit. Here we provide an overview of opportunities identified in the clinical research infrastructure during the West Africa EVD epidemic and the SPRN activities to meet the ongoing challenges in the context of Ebola virus and other special pathogens.

Alcohol and other drug misuse are significant but neglected public health issues in conflict-affected populations. In this article, we review the literature on the challenges and strategies for implementing substance misuse treatment and prevention services in conflict and post-conflict settings in low- and middle-income countries. We identified nine studies describing interventions in conflict-affected populations residing in Afghanistan, Croatia, India, Kenya, Kosovo, Pakistan, and Thailand. Six of these nine studies focused on refugee populations. Reports revealed challenges to intervention implementation, as well as promising practices and recommendations for future implementation that we characterized as existing in the inner and outer contexts of an implementing organization. Challenges existing in the outer context included low political prioritization, lack of coordination and integration, and limited advocacy for access to substance misuse services. Challenges within the inner context related to competing priorities and a shortage of providers. Resource limitations existed in both the inner and outer contexts. Stigma was a challenge that threatened implementation and utilization of substance use services in situations when substance use interventions were not congruent with the roles, structure, values, and authority of the system or implementing organization. Future research should focus on developing, applying, and evaluating strategies for overcoming these challenges in order to make progress toward meeting the need for substance misuse services in conflict-affected populations.

Introduction/ProblemFor more than 60 years, Colombia experienced an armed conflict involving government forces, guerrillas, and other illegal armed groups. Violence, including torture and massacres, has caused displacement of entire rural communities to urban areas. Lack of information on the problems displaced communities face and on their perceptions on potential solutions to these problems may prevent programs from delivering appropriate services to these communities. This study explores the problems of Afro-Colombian survivors from two major cities in Colombia; the activities they do to take care of themselves, their families, and their community; and possible solutions to these problems.

Ability to function in tasks and activities is an important aspect of daily living. There are factors that increase the risk for impaired functioning, such as experiences of domestic violence (DV) and other trauma types, and factors that provide a buffer to existing risks and allow the individual to continue and build functioning, such as access to social resources. This cross-sectional study investigated the direct effects of DV and access to social resources (perceived social support, social integration, and frequency of social contact), as well as their potential interactive effects, on daily functioning among 894 male and female trauma survivors who attended primary care clinics in Kurdistan, Iraq in 2009 and 2010. Experiencing DV was not associated with functioning for males (p=.15) or females (p=.60), suggesting that in the context of a trauma-affected sample, the experience of DV may not significantly increase the risk for functional impairment. Greater amounts of social integration were associated with less functional impairment among males (p<.01) and females (p<.05); social integration was associated with less functional impairment among males only (p<.01); and frequency of social contact was associated with less functional impairment among females only (p<.05), indicating that the association between social resource type and functioning differed by gender. Standardized beta coefficients indicated that social resources had a stronger effect on functioning among men compared to women. Among males who experienced DV, social integration was the only social resource associated with less functional impairment (p<.01); among male trauma survivors who did not experience DV, social support was the only resource associated with less functional impairment (p<.01). Further investigation into the association of social resources with functioning and how these differ by gender and DV exposure is warranted to inform intervention strategies for survivors of DV and other traumas in post-conflict settings.

With one billion people on the move or having moved in 2018, migration is a global reality. International migration has increased to 258 million, and the numbers of refugees and people displaced by conflict, natural disasters, and climate change are at their highest levels: 22 and 40 million, respectively. Despite negative political narratives, migration is not overwhelming high-income countries—instead, it takes place mostly between low-income and middle-income countries and most people are migrating for work. By and large, migration is a positive and diverse experience. But migration has also become a political lightning rod. 

Exposure to violence has negative consequences on mental health. Armed-conflict in Colombia has widely affected Afro-descendants in the Pacific region. Evidence regarding effectiveness of mental health interventions is lacking in low-income settings, especially in areas with active conflict. The objective of this study is to evaluate an individualized Common Elements Treatment Approach (CETA), a transdiagnostic psychotherapy model based on Cognitive-Behavioral Therapy, for adult trauma survivors.

Lack of legal immigration status is associated with poor HIV-related outcomes for immigrant Latinx sexual and gender minorities (LSGM). LSGM often meet eligibility criteria for legal immigration relief. A Medical-Legal Partnership (MLP) may thus be strategic to improve their health. We know little about the challenges LSGM face during the immigration legal process. We conducted in-depth interviews with six key informants and sixteen LSGM who recently applied for immigration legal relief. We coded and analyzed the data for emergent themes. Challenges to instituting an MLP for LSGM included lack of specialized training on working with SGM for immigration attorneys, and for clients: knowledge about legal deadlines, lack of housing and family support, and re-traumatizing experiences. Clients' outcomes were positive when attorneys and mental health providers collaborated. For LSGM, the benefits of immigration relief included reduced HIV risk. An MLP that addresses the surmountable challenges could improve HIV-related outcomes among LSGM.

To evaluate effectiveness of point-of-use water treatment in improving treatment of children affected by severe acute malnutrition (SAM).

To examine the demographic characteristics and mental health of women in rural Zambia who experienced physical intimate partner violence (IPV) postpartum.

Obtaining accurate and valid measurements of disruptive behavior disorders remains a challenge in non-Western settings due to variability in societal norms for child behavior and a lack of tools developed outside of Western contexts. This paper assesses the reliability and construct validity of the Disruptive Behavior International Scale - Nepal version (DBIS-N)-a scale developed using ethnographic research in Nepal-and compares it with a widely used Western-derived scale in assessing locally defined child behavior problems.

Abstract

In our work as clinicians, researchers, and immigrant rights advocates, we have noted increased anxiety about the possibility of deportation and disruptions in care among immigrants with HIV. Before the 2016 US elections, patients rarely asked about HIV treatment in their home countries. However, since the increase in anti-immigrant rhetoric and arrests by US Immigration and Customs Enforcement, patients have voiced concerns about the availability of HIV treatment in their home countries much more frequently. Although antiretroviral therapy is available throughout Latin America, access depends on economic, social, and political circumstances. Maintaining uninterrupted continuity of care among immigrants held in detention or deported to their home countries is challenging. In this Viewpoint, we identify periods of particular vulnerability for immigrants during deportation proceedings, from initial detention to deposition in their country of origin. We discuss the effect of enhanced immigration enforcement on the health and wellbeing of HIV-infected immigrants, and on public health. Finally, we also discuss recommendations for clinicians, immigration authorities, and public health institutions in the USA and in receiving countries.

The use of oral cholera vaccine (OCV) has increased since 2011, when Shanchol, the first OCV suitable for large-scale use, became available. Médecins Sans Frontières considers OCVs an essential cholera outbreak control tool and has contributed to generating new evidence on OCV use in outbreaks. We showed that large-scale mass campaigns are feasible during outbreaks, documented high short-term effectiveness and showed that vaccines are likely safe in pregnancy. We found that a single-dose regimen has high short-term effectiveness, making rapid delivery of vaccine during outbreaks easier, especially given the on-going global vaccine shortage. Despite progress, OCV has still not been used widely in some of the largest recent outbreaks and thousands of cholera deaths are reported every year. While working towards improving our tools to protect those most at-risk of cholera, we must strive to use all available effective interventions in efficient ways, including OCV, to prevent avoidable deaths today.

Dureab and colleagues concur with our call for urgent measures to enhance cholera preparedness and response in Yemen to stop the outbreak that has persisted for more than 2 years. However, they challenge our finding that the large second epidemic wave was associated with the start of the rainy season from April to May, 2017. They suggest that rainfall is unlikely to be a major risk factor for cholera transmission in Yemen because cholera and rainfall are spatially and temporally variable within the country, and because our analyses used modelled and not measured estimates of precipitation.

Although the World Health Organization (WHO) has recommended guidelines for the treatment of opioid dependence, there are myriad challenges to successfully implementing such guidelines in resource constrained settings, such as in low and middle-income countries (LMICs). To highlight these challenges, this paper presents a clinical case study of an adolescent study participant in a randomized controlled trial comparing two counseling programs in Lusaka, Zambia.

In Kachin State, Myanmar, collapse of a ceasefire in 2011 has resulted in widespread exposure to conflict and ongoing internal displacement. Such exposures are known risk factors for mental health and psychosocial (MHPS) problems, yet mental health services for children and youth are typically scarce in such circumstances. Following evaluation of a mental health treatment for adult trauma survivors on the Thailand-Myanmar border, our study team received requests to support the development of a similar intervention for displaced children in Kachin State. To inform this work, we conducted a brief qualitative needs assessment to explore priority MHPS problems among this population.

The global population of older adults (60 years and older) has been growing steadily; however, inadequate attention is given to the health needs of older persons, particularly within contexts of conflict and migration. This paper reports findings from the qualitative phase of an investigation assessing the mental health status of older adult internally displaced persons (IDPs) in Georgia, a country in the South Caucasus. The study aimed to assess community-wide social and health problems among older adult IDPs, with a focus on mental health problems and healthy functioning, as well as terminology used to describe these problems. Free-list interviews with older adult IDPs (n = 75) and key informant interviews with community members and service providers (n = 45) were conducted in 2010-2011 in three regions of Georgia: Tbilisi, Shida Kartli, and Samegrelo. Findings demonstrated that older IDPs experienced symptoms of distress that could be clustered into depression-like and anxiety-like syndromes. Participants described other psychosocial problems among older IDPs, including feelings of abandonment, isolation, and passivity, as well as conflicts in the family. All problems were linked with displacement-related experiences, such as difficulties with integration, grief, and war trauma. The expression of displacement-related problems was identified as an idiom of distress for this population. Older IDPs coped with these problems through social support mechanisms, including socializing, helping each other, working, and participating in the community. Key modalities for redressing older IDPs' psychosocial problems, improving quality of life, and achieving healthy 'aging-in-displacement' include: promoting social connectedness and community engagement, drawing on IDPs' skills, identifying new social roles, and strengthening social support networks.

Female sex workers (FSW) constitute a highly vulnerable population challenged by numerous co-existing, or syndemic, risk factors. FSW also display resilience to these, and some evidence suggests that resilience may be associated with protective factors that improve health outcomes. We conducted in-depth interviews with indirect sex workers (n = 11) and their clients (n = 18). Interviews were coded utilizing an iterative, modified constant comparison method to identify emergent themes. We identified five syndemic risk factors (difficulty finding work due to undocumented status, shame and mental health hardship, lack of social support, alcohol use, and violence) and five resilient factors (rationalizing sex work, identifying as a "decent" woman, fulfilling immigrant goals, reducing alcohol consumption, and creating rules to reduce risk of violence and HIV/STIs). Understanding the syndemic risk factors and resiliency developed by FSW is important to develop tailored, strength-based interventions for HIV/STIs and other risks.

Background: Following the Nepal earthquake in April 2015, UNFPA estimated that 1.4 million women of reproductive age were affected, with approximately 93,000 pregnant and 28,000 at risk of sexual violence. A set of priority reproductive health (RH) actions, the Minimum Initial Services Package (MISP), was initiated by government, international and local actors. The purpose of this study was to identify the facilitators and barriers affecting the implementation of priority RH services in two districts.

Methods: In September 2015, a mixed methods study design was used in Kathmandu and Sindhupalchowk districts to assess the implementation of the priority RH services five months post-earthquake. Data collection activities included 32 focus group discussions with male and female participants aged 18–49; 26 key informant interviews with RH, gender-based violence (GBV), and human immunodeficiency virus (HIV) experts; and 17 health facility assessments.

Results: The implementation of priority RH services was achieved in both districts. In Kathmandu implementation of emergency RH services started within days of the earthquake. Facilitating factors for successful implementation included disaster preparedness; leadership and commitment among national, international, and district level actors; resource mobilization; strong national level coordination; existing reproductive and child health services and community outreach programs; and supply chain management. Barriers included inadequate MISP training for RH coordinators and managers; weak communication between national and district level stakeholders; inadequate staffing; under-resourced and fewer facilities in rural areas; limited attention given to local GBV and HIV organizations; low availability of clinical management of rape services; and low awareness of GBV services and benefits of timely care.

Conclusion: Ensuring RH is included in emergency preparedness and immediate response efforts and is continued through the transition to comprehensive care is critical for national governments and humanitarian response agencies. The MISP for RH remains a critical component of response efforts, and the humanitarian community should consider these learnings in future emergency response.
