Informal healthcare provision in Lebanon: an adaptive mechanism among displaced Syrian health professionals in a protracted crisis

Abstract: Background: Syrian healthcare workers (HCWs) are among those who fled the Syrian conflict only to face further social and economic challenges in host countries. In Lebanon, this population group cannot formally practice, yet many are believed to be operating informally. These activities remain poorly documented and misunderstood by the academic, policy and humanitarian communities. This study aims to understand mechanisms of informal provision of services, the facilitators and barriers for such practices and to present policy recommendations for building on this adaptive mechanism. Method: A qualitative descriptive study based on an in-depth interview approach with a sample of Syrian informal healthcare workers (IHCWs) residing in Lebanon was adopted. Known sponsor networks followed by snowball sampling approaches were used to recruit participants. Data collection occurred between September and December 2017. All interviews were audio-recorded, transcribed and translated into English. An inductive thematic analysis was used. Results: Twenty-two participants were recruited. Motivational factors that led HCWs to practice informally were personal (e.g. source of income/livelihood), societal (cultural competency), and need to fulfill a gap in the formal health service sector. Being connected to a network of IHCWs facilitated initiation of the informal practice until eventually becoming part of a community of informal practice. The central challenge was the informal nature of their practice and its negative consequences. Most IHCWs were afraid of arrest by the government upon identification. Most interviewees indicated being discriminated against by host communities in the form of differential wages and tense interpersonal relationships. Almost all recommended a change in policy allowing them to practice formally under a temporary registration until their return to Syria. Conclusion: Our study confirmed the presence of IHCWs operating in Lebanon. Despite its informal nature, participants perceived that this practice was filling a gap in the formal health system and was helping to alleviate the burden of IHCWs and refugee health needs. In line with interviewees’ views, we recommend that policy decision makers within humanitarian agencies and the Government of Lebanon explore the possibilities for allowing temporary registration of displaced Syrian IHCW to benefit local host communities and refugee populations

Role of HVR1 sequence similarity in the cross-genotypic neutralization of HCV

Despite available treatments, a prophylactic HCV vaccine is needed to achieve elimination targets. HCV vaccine development has faltered largely because the extreme diversity of the virus limits the protective breadth of vaccine elicited antibodies. It is believed that the principle neutralizing epitope in natural infection, HVR1, which is the most variable epitope in HCV, mediates humoral immune escape. So far, efforts to circumvent HVR1 interference in the induction and function of conserved targeting Ab have failed. Efforts to understand factors contributing to cross-neutralization of HVR1 variants have also been limited. Here, following mouse immunizations with two patient-derived HVR1 peptides, we observe cross-genotype neutralization of variants differing at 15/21 positions. Surprisingly, sequence similarity was not associated with cross-neutralization. It appeared neutralization sensitivity was an intrinsic feature of each variant, rather than emergent from the immunogen specific Ab response. These findings provide novel insight into HVR1-mediated immune evasion, with important implications for HCV vaccine design

A bivalent HCV peptide vaccine elicits pan-genotypic neutralizing antibodies in mice

© 2020 Elsevier Ltd Vaccine development for antigenically variable pathogens has faltered because extreme genetic diversity precludes induction of broadly neutralizing antibodies (nAB) with classical vaccines. Here, using the most variable epitope of any known human pathogen (HVR1 of HCV), we describe a novel approach capable of eliciting broadly neutralizing antibodies targeting highly variable epitopes. Our proof-of-concept vaccine elicited pan-genotypic nAB against HCV variants differing from the immunogen sequences by more than 70% at the amino acid level. These findings suggest broadly nAB to highly variable pathogens can be elicited by vaccines designed to target physicochemically conserved residues within hypervariable epitopes

Public health effects of travel-related policies on the COVID-19 pandemic: A mixed-methods systematic review

Objectives: To map travel policies implemented due to COVID-19 during 2020, and conduct a mixed methods systematic review of health effects of such policies, and related contextual factors. Design: Policy mapping and systematic review. Data sources and Eligibility Criteria: for the policy mapping, we searched websites of relevant government bodies and used data from the Oxford COVID-19 Government Response Tracker for a convenient sample of 31 countries across different regions. For the systematic review, we searched Medline (Ovid), PubMed, EMBASE, the Cochrane Central Register of Controlled Trials and COVID-19 specific databases. We included randomized controlled trial, non-randomized studies, modeling studies, and qualitative studies. Two independent reviewers selected studies, abstracted data and assessed risk of bias. Results: Most countries adopted a total border closure at the start of the pandemic. For the remainder of the year, partial border closure banning arrivals from some countries or regions was the most widely adopted measure, followed by mandatory quarantine and screening of travelers. The systematic search identified 69 eligible studies, including 50 modeling studies. Both observational and modeling evidence suggest that border closure may reduce the number of COVID-19 cases, disease spread across countries and between regions, and slow the progression of the outbreak. These effects are likely to be enhanced when implemented early, and when combined with measures reducing transmission rates in the community. Quarantine of travelers may decrease the number of COVID-19 cases but its effectiveness depends on compliance and enforcement and is more effective if followed by testing, especially when less than 14 day-quarantine is considered. Screening at departure and/or arrival is unlikely to detect a large proportion of cases or to delay an outbreak. Effectiveness of screening may be improved with increased sensitivity of screening tests, awareness of travelers, asymptomatic screening, and exit screening at country source. While four studies on contextual evidence found that the majority of the public is supportive of travel restrictions, they uncovered concerns about the unintended harms of those policies.Peer Reviewe

Factors associated with completion of bowel cancer screening and the potential effects of simplifying the screening test algorithm

BACKGROUND: The primary colorectal cancer screening test in England is a guaiac faecal occult blood test (gFOBt). The NHS Bowel Cancer Screening Programme (BCSP) interprets tests on six samples on up to three test kits to determine a definitive positive or negative result. However, the test algorithm fails to achieve a definitive result for a significant number of participants because they do not comply with the programme requirements. This study identifies factors associated with failed compliance and modifications to the screening algorithm that will improve the clinical effectiveness of the screening programme. METHODS: The BCSP Southern Hub data for screening episodes started in 2006–2012 were analysed for participants aged 60–69 years. The variables included age, sex, level of deprivation, gFOBt results and clinical outcome. RESULTS: The data set included 1 409 335 screening episodes; 95.08% of participants had a definitively normal result on kit 1 (no positive spots). Among participants asked to complete a second or third gFOBt, 5.10% and 4.65%, respectively, failed to return a valid kit. Among participants referred for follow up, 13.80% did not comply. Older age was associated with compliance at repeat testing, but non-compliance at follow up. Increasing levels of deprivation were associated with non-compliance at repeat testing and follow up. Modelling a reduction in the threshold for immediate referral led to a small increase in completion of the screening pathway. CONCLUSIONS: Reducing the number of positive spots required on the first gFOBt kit for referral for follow-up and targeted measures to improve compliance with follow-up may improve completion of the screening pathway

Protocol for Nearly Full-Length Sequencing of HIV-1 RNA from Plasma

Nearly full-length genome sequencing of HIV-1 using peripheral blood mononuclear cells (PBMC) DNA as a template for PCR is now a relatively routine laboratory procedure. However, this has not been the case when using virion RNA as the template and this has made full genome analysis of circulating viruses difficult. Therefore, a well-developed procedure for sequencing of full-length HIV-1 RNA directly from plasma was needed. Plasma from U.S. donors representing a range of viral loads (VL) was used to develop the assay. RNA was extracted from plasma and reverse-transcribed. Two or three overlapping regions were PCR amplified to cover the entire viral genome and sequenced for verification. The success of the procedure was sensitive to VL but was routinely successful for VL greater than 105 and the rate declined in proportion to the VL. While the two-amplicon strategy had an advantage of increasing the possibility of amplifying a single species of HIV-1, the three-amplicon strategy was more successful in amplifying samples with low viral loads. This protocol provides a useful tool for molecular analysis to understand the HIV epidemic and pathogenesis, as well as diagnosis, therapy and future vaccine strategies

Cenas Urbanas Performance e política nas ruas de Florianópolis

TCC (graduação) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Curso de Ciências Sociais.A escolha da rua como espaço para realização das performances dos grupos ERRO Grupo, Grupo Experiência Trânsito e Corpo (E.T.C.) e Coletivo Urbe, na cidade de Florianópolis, apresenta-se como um modo não-convencional do fazer artístico. O presente trabalho pretende, a partir de uma participação observante (WACQUANT, 2002), investigar e explorar os elementos que compõem as práticas artísticas desses grupos, buscando compreender em que medida tais elementos possuem um sentido político. Desse modo, as questões que guiam esta pesquisa são: Por que fazer da rua um palco? Por que esse espaço é, afinal, importante para os artistas que nele se apresentam? Em que medida esta é uma escolha política? As experiências vivenciadas mostram que tais sentidos políticos se relacionam com lo político (MOUFFE, 2011), isto é, referem-se à escolha estética que, em alguma medida, define esses grupos substantivamente. Essa escolha desdobra-se em aspectos que serão analisados nesta pesquisa, como por exemplo, os lugares em que as performances acontecem; a forma como os grupos se apropriam do mesmo e como isso afeta a performance; as dualidades ator/personagem e ator/espectador; e seus textos dramatúrgicos; elementos estes que, de alguma forma, são desconstruídos nessas experiências. Observamos que, embora apresentem diferenças, as práticas artísticas de tais grupos podem ser compreendidas a partir de um mesmo sentido político, representado por um conjunto de atributos que constituem suas performances.The choice of having the street where the performances take place, as made by the groups ERRO Grupo, Grupo Experiência Trânsito e Corpo (E.T.C.) e Coletivo Urbe, in Florianópolis, is an unconventional way of doing art. The present work intends, from an observant participation (WACQUANT, 2002), to investigate and explore the elements that compose the artistic practices of these groups, trying to understand to what extent these elements have a political meaning. Thus, the questions that guide this research are: Why make the street a stage? Why is this space, after all, important for the artists who present themselves in it? To what extent is this a political choice? Experiences during fieldwork show that these political meanings are related to lo político (MOUFFE, 2011), that is, they refer to the aesthetic choice that, to some extent, defines these groups substantively. This choice unfolds into aspects that will be analyzed in this research, for example, the places in which the performances take place; how the groups appropriate it and how it affects performance; the dualities actor / character and actor / spectator; and their dramaturgical texts; elements that are somehow deconstructed in these experiences. We observe that, although there might be differences among the artistic practices of such groups, they can be understood from the same political sense, represented by a set of attributes that constitute their performances
