RESUMO

Background: The 2022-2024 global mpox outbreak, occurring primarily in the sexual networks of gay, bisexual and other men who have sex with men (GBMSM), has not been accompanied by a focus on patient perspectives of illness. We explore the experiences of GBMSM diagnosed with mpox in England to understand needs for social and clinical support. Methods: In-depth interviews (March/July 2023) were conducted with 22 GBMSM diagnosed with mpox in 2022, randomly selected from a national mpox surveillance database, and 4 stakeholders from clinical/community-based organisations. Interviews covered experiences of illness, testing, diagnosis, treatment and contact tracing, and were recorded, transcribed and analysed with a thematic framework. Findings: Media coverage drawing on homophobic stereotypes around sex between men contributed to feelings of stigma and shame. GBMSM living with HIV appeared to cope better with mpox stigma, drawing on their experiences of being diagnosed with HIV for resilience. Younger GBMSM with less experience of stigmatising illness found mpox diagnosis more traumatic and sometimes required support beyond what was provided. Accessing testing could be complicated when healthcare professionals did not recognise mpox symptoms. Men felt information on course of illness, isolation and vaccination after recovery was often inconsistent and contradictory. GBMSM described that care from sexual health and infectious disease units usually better met their emotional and medical needs. This was frequently linked by men to these services having skills in working with the GBMSM community and managing infection risk sensitively. General hospital services and centralised contact tracing could increase feelings and experiences of stigma as some staff were perceived to lack skills in supporting GBMSM and, sometimes, clinical knowledge. Long-term impacts described by men included mental health challenges, urethral/rectal symptoms and life-changing disability. Interpretation: In this study stigma was a central feature of mpox illness among GBMSM and could be exacerbated or lessened depending on the clinical and social support provided. Involving communities affected by outbreaks in co-producing, planning and delivering care (including contact-tracing) may help improve support provided.

RESUMO

BACKGROUND: The CLASP IID randomized trial (Edwards PASCAL TrAnScatheter Valve RePair System Pivotal Clinical Trial) demonstrated the safety and effectiveness of the PASCAL system for mitral transcatheter edge-to-edge repair (M-TEER) in patients at prohibitive surgical risk with significant symptomatic degenerative mitral regurgitation (DMR). OBJECTIVES: This study describes the echocardiographic methods and outcomes from the CLASP IID trial and analyzes baseline variables associated with residual mitral regurgitation (MR) ≤1+. METHODS: An independent echocardiographic core laboratory assessed echocardiographic parameters based on American Society of Echocardiography guidelines focusing on MR mechanism, severity, and feasibility of M-TEER. Factors associated with residual MR ≤1+ were identified using logistic regression. RESULTS: In 180 randomized patients, baseline echocardiographic parameters were well matched between the PASCAL (n = 117) and MitraClip (n = 63) groups, with flail leaflets present in 79.2% of patients. Baseline MR was 4+ in 76.4% and 3+ in 23.6% of patients. All patients achieved MR ≤2+ at discharge. The proportion of patients with MR ≤1+ was similar in both groups at discharge but diverged at 6 months, favoring PASCAL (83.7% vs 71.2%). Overall, patients with a smaller flail gap were significantly more likely to achieve MR ≤1+ at discharge (adjusted OR: 0.70; 95% CI: 0.50-0.99). Patients treated with PASCAL and those with a smaller flail gap were significantly more likely to sustain MR ≤1+ to 6 months (adjusted OR: 2.72 and 0.76; 95% CI: 1.08-6.89 and 0.60-0.98, respectively). CONCLUSIONS: The study used DMR-specific echocardiographic methodology for M-TEER reflecting current guidelines and advances in 3-dimensional echocardiography. Treatment with PASCAL and a smaller flail gap were significant factors in sustaining MR ≤1+ to 6 months. Results demonstrate that MR ≤1+ is an achievable benchmark for successful M-TEER.

RESUMO

BACKGROUND: Refugee healthcare workers (HCWs) can make important contributions in host countries, particularly in the wake of the ongoing COVID-19 pandemic, which has exacerbated existing shortages of frontline HCWs. However, refugee HCWs often face challenges entering the labour markets of such countries even where needs exist. Syria's decade-long conflict has forced thousands of HCWs from their homes; however, data on this population are limited, impeding the formation of policies that can support them. This study explores the experiences of Syrian refugee HCWs in Egypt. METHODS: Key informants (KIs) were selected using purposive and snowball sampling method and semi-structured interviews were conducted in person in Cairo and remotely from the UK during July 2019. Interviews were conducted in Arabic and analysed using a combined deductive and inductive thematic analysis framework after transcription into English. RESULTS: Fifteen KI interviews were analysed. The main emerging themes from the qualitative interviews are those relating to 1. Education, training, and licensing 2. Politics and bureaucracy 3. Societal factors 4. Economic factors. Political changes in Egypt altered opportunities for Syrian HCWs over time; however, refugee HCWs broadly reported acceptance among Egyptian patients and colleagues. Bureaucratic factors which impede the ability of Syrian refugee HCWs to obtain a full license to practice and leave to remain and the absence of clearly defined policies were reported as barriers. Economic factors including the risk of economic exploitation e.g. in the informal sector and financial insecurity were noted to have a negative psychosocial impact. CONCLUSIONS: This is the first qualitative research study which explores the experiences of Syrian refugee HCWs in Egypt. It adds to the sparse literature on the topic of Syrian refugee HCWs but provides evidence for further discussions on how to support refugee HCWs in Egypt and in other host countries in the region. Though interviews were conducted before the COVID-19 pandemic, the pandemic itself lends urgency to the discussion around refugee HCWs on an international level.

RESUMO

The COVID-19 pandemic has renewed interest in streamlining processes which allow refugee doctors and other healthcare workers to make up for the shortfall in healthcare delivery, which many countries are facing increasingly. The protracted conflict in Syria is the biggest driver of forced displacement internationally with refugees, including healthcare workers seeking safety in host countries, however many face challenges to entering the workforce in a timely manner. The majority are in countries surrounding Syria (Lebanon, Jordan and Turkey) however the restrictive labour policies in these countries, particularly for healthcare workers have forced many to look further afield to Europe or the Gulf. Egypt's context is interesting in this regard, as it hosts a smaller number of registered Syrian refugees and was initially welcoming of Syrian medical students and doctors. However, recent socio-political changes have led to restrictions in training and work, leading doctors who initially considering staying in Egypt to increasingly consider it a transit country rather than a destination country. Here, we explore the processes by which Syrian doctors in Egypt can work and how documented policies may differ to practice. We do this through a document review and from the first-hand experiences of the authors.

RESUMO

Current methods for measuring deoxyribonucleoside triphosphates (dNTPs) employ reagent and labor-intensive assays utilizing radioisotopes in DNA polymerase-based assays and/or chromatography-based approaches. We have developed a rapid and sensitive 96-well fluorescence-based assay to quantify cellular dNTPs utilizing a standard real-time PCR thermocycler. This assay relies on the principle that incorporation of a limiting dNTP is required for primer-extension and Taq polymerase-mediated 5-3' exonuclease hydrolysis of a dual-quenched fluorophore-labeled probe resulting in fluorescence. The concentration of limiting dNTP is directly proportional to the fluorescence generated. The assay demonstrated excellent linearity (R(2) > 0.99) and can be modified to detect between ∼0.5 and 100 pmol of dNTP. The limits of detection (LOD) and quantification (LOQ) for all dNTPs were defined as <0.77 and <1.3 pmol, respectively. The intra-assay and inter-assay variation coefficients were determined to be <4.6% and <10%, respectively with an accuracy of 100 ± 15% for all dNTPs. The assay quantified intracellular dNTPs with similar results obtained from a validated LC-MS/MS approach and successfully measured quantitative differences in dNTP pools in human cancer cells treated with inhibitors of thymidylate metabolism. This assay has important application in research that investigates the influence of pathological conditions or pharmacological agents on dNTP biosynthesis and regulation.
