RESUMO

INTRODUCTION: Since 2013, the European Testing Week (ETW) awareness campaign has become a key regional event influencing testing efforts for HIV, viral hepatitis, and sexually transmitted infections (STIs) through participation of 720 organizations. Here, we report on a survey from May to June 2022 aimed at assessing the participant-reported impact of the campaign. METHODS: All past and current participating organizations were asked to complete an online questionnaire between 12 May and 17 June 2022. Multiple choice and open-text questions included organization information, usage of ETW to engage in local testing-related activities, and the effect of a regional campaign to reach a wider audience and generate impact. RESULTS: Of the 52 respondents, 34 (65%) stated first participating in ETW 5-10 years ago. ETW was used for awareness raising by 40 respondents (83%), new testing activities by 37 (77%), advocacy initiatives by 15 (31%), and training/capacity building by 18 (38%). For awareness raising, 95% used ETW to highlight the importance of and to encourage testing; for new testing activities, 74% used ETW to reach new groups. In total, 44 (85%) reported added benefits of a Europe-wide campaign compared with national/local campaigns, particularly the increased visibility and collaboration opportunities. Impact at the local level was observed by 24 (51%), and impact at a national level was observed by 20 (43%). A total of 28 (79%) reported increases in the number of tests performed and 25 (75%) reported increases in clients accessing services. CONCLUSIONS: Regional awareness campaigns reach wider audiences, boost local and national efforts to increase testing, and sensitize key populations about the critical value of testing compared with local/national campaigns.

RESUMO

In Brazil, the use of Eucalyptus is focused on the production of wood or pulp for the paper industry but without any general recovery of waste, with leaves and branches being left on the ground. One possibility is to use these residues as raw materials in the production of industrially relevant and value-added compounds such as essential oil. The aim of the present study was to investigate the chemical composition, yield, anti-inflammatory/antinociceptive activities, and acute toxicity in mice, as well as the antimicrobial effects of essential oils from the leaves of 7 varieties of Eucalyptus and hybrids against Escherichia coli, Staphylococcus aureus, and Candida albicans. The extraction of oils was carried out using hydrodistillation, and they were analyzed by gas chromatography coupled to mass spectrometry. Urocam and Grancam were the plants that obtained the highest oil yield, with yields of 3.32 and 2.30%, respectively. The main chemical components identified in these plants were 1.8 cineole and α-pinene. The antinociceptive effect of the 7 oils (50 mg/kg, p.o.) was initially assessed in the acetic acid-induced writhing test. In this assay, a significant (p < 0.05) antinociceptive/anti-inflammatory effect was observed from 4 tested essential oils (E. benthamii, E. saligna, and the hybrids Urocam and Grancam) when compared to the vehicle-treated group. This effect was then confirmed in the formalin-induced paw licking test. No toxicological effects or alterations were observed in motor coordination after the administration of the studied oils to the animals. In the antimicrobial evaluation, the seven essential oils inhibited the growth of S. aureus, E. coli, and C. albicans at different concentrations. Collectively, these results demonstrate that the essential oil from the leaves and branches of Eucalyptus species and varieties present potential biomedical applications and represent a source of antimicrobial and/or anti-inflammatory compounds.

RESUMO

BACKGROUND: COVID-19 affected testing for HIV, viral hepatitis and sexually transmitted infections (STIs) worldwide. We aimed to assess the impact of the COVID-19 pandemic on community-based voluntary, counselling and testing (CBVCT) services for those infections in the WHO European Region. METHODS: An online survey was distributed between 14 October and 13 November 2020 to testing providers in the WHO European Region. Key questions included: impact on testing volume, reasons for this impact, measures to mitigate, economic effects, areas where guidance or support were needed. A descriptive analysis on data reported by CBVCT services was performed. RESULTS: In total, 71 CBVCT services from 28 countries completed the survey. From March to May 2020, compared to the same period in 2019, most respondents reported a very major decrease (>50%) in the volume of testing for all the infections, ranging from 68% (Chlamydia) to 81% (HCV), and testing levels were not recovered during post-confinement. Main reasons reported were: site closure during lockdown (69.0%), reduced attendance and fewer appointments scheduled (66.2%), reduced staff (59.7%), and testing only by appointment (56.7%). Measures implemented to mitigate the decreased testing were remote appointments (64.8%), testing by appointment (50.7%), referral to other sites (33.8%), testing campaigns (35.2%) and promotion of self-testing (36.6%). Eighty-two percent of respondents reported a need for guidance/support. CONCLUSION: Results suggest that people attending CBVCT services experienced reductions in access to testing compared to before the pandemic. National governmental agencies need to support European CBVCT services to ensure recovery of community counselling and testing.

RESUMO

INTRODUCTION: In recent years, HIV testing frequency has increased, resulting in more people being diagnosed during seroconversion with a temporarily low CD4 count. Using the current consensus definition of late HIV presentation ('presenting for care with a CD4 count < 350 cells/µL or an AIDS-defining event, regardless of CD4 count') these individuals would be incorrectly assigned as being diagnosed late. METHODS: In spring 2022, a European expert group convened to revise the current late HIV presentation consensus definition. A survey on data availability to apply this revised definition was sent to nominated European focal points responsible for HIV surveillance (n = 53). RESULTS: Experts agreed that the updated definition should refer to late HIV diagnosis rather than presentation and include the following addition: People with evidence of recent infection should be reclassified as 'not late', with evidence of recent infection considered hierarchically. The individual must have: (i) laboratory evidence of recent infection; (ii) a last negative HIV test within 12 months of diagnosis; or (iii) clinical evidence of acute infection. People with evidence of being previously diagnosed abroad should be excluded. A total of 18 countries responded to the survey; 83% reported capturing CD4 count and/or AIDS at diagnosis through national surveillance, 67% captured last negative test and/or previous HIV diagnosis, 61% captured seroconversion illness at diagnosis and 28% captured incident antibody results. CONCLUSIONS: Accurate data on late diagnosis are important to describe the effects of testing programmes. Reclassification of individuals with recent infection will help to better identify populations most at risk of poor HIV outcomes and areas for intervention.

RESUMO

Technical advances in diagnostic techniques have permitted the possibility of multi-disease-based approaches for diagnosis and treatment monitoring of several infectious diseases, including tuberculosis (TB), human immunodeficiency virus (HIV), viral hepatitis and sexually transmitted infections (STI). However, in many countries, diagnosis and monitoring, as well as disease response programs, still operate as vertical systems, potentially causing delay in diagnosis and burden to patients and preventing the optimal use of available resources. With countries facing both human and financial resource constraints, during the COVID-19 pandemic even more than before, it is important that available resources are used as efficiently as possible, potential synergies are leveraged to maximise benefit for patients, continued provision of essential health services is ensured. For the infectious diseases, TB, HIV, hepatitis C (HCV) and STI, sharing devices and integrated services starting with rapid, quality-assured, and complete diagnostic services is beneficial for the continued development of adequate, efficient and effective treatment strategies. Here we explore the current and future potential (as well as some concerns), importance, implications and necessary implementation steps for the use of platforms for multi-disease testing for TB, HIV, HCV, STI and potentially other infectious diseases, including emerging pathogens, using the example of the COVID-19 pandemic.

RESUMO

We present the outcomes of the HepHIV 2021 Lisbon & virtual conference held on 5-7 May 2021, including a Call to Action addressing policy and practice implications in the field of earlier and integrated testing for HIV, viral hepatitis, STI and TB and in light of lessons learned from the COVID-19 pandemic. Conference presentations showed that combination prevention and integrated testing and care models for multiple infectious diseases are necessary and feasible in diverse settings. Successful examples of service and system adaptations developed to mitigate impact of the pandemic were shared. Aiming to ensure greater equity in health in current and future health policies and programmes and address the adverse effects of COVID-19, we must learn from the many innovative approaches to service delivery developed in response to the pandemic, many of which have the potential to reach people whose needs were not met by existing models.

RESUMO

BackgroundIn Europe, HIV disproportionately affects men who have sex with men (MSM), people who inject drugs (PWID), prisoners, sex workers, and transgender people. Epidemiological data are primarily available from national HIV case surveillance systems that rarely capture information on sex work, gender identity or imprisonment. Surveillance of HIV prevalence in key populations often occurs as independent studies with no established mechanism for collating such information at the European level.AimWe assessed HIV prevalence in MSM, PWID, prisoners, sex workers, and transgender people in the 30 European Union/European Economic Area countries and the United Kingdom.MethodsWe conducted a systematic literature review of peer-reviewed studies published during 2009-19, by searching PubMed, Embase and the Cochrane Library. Data are presented in forest plots by country, as simple prevalence or pooled across multiple studies.ResultsEighty-seven country- and population-specific studies were identified from 23 countries. The highest number of studies, and the largest variation in HIV prevalence, were identified for MSM, ranging from 2.4-29.0% (19 countries) and PWID, from 0.0-59.5% (13 countries). Prevalence ranged from 0.0-15.6% in prisoners (nine countries), 1.1-8.5% in sex workers (five countries) and was 10.9% in transgender people (one country). Individuals belonging to several key population groups had higher prevalence.ConclusionThis review demonstrates that HIV prevalence is highly diverse across population groups and countries. People belonging to multiple key population groups are particularly vulnerable; however, more studies are needed, particularly for sex workers, transgender people and people with multiple risks.

RESUMO

BACKGROUND: Maximising access to testing by targeting more than one infection is effective in identifying new infections in settings or populations. Within the EU funded Joint Action INTEGRATE, this paper examined the feasibility and impact of expanding integrated testing for HIV, hepatitis C (HCV), chlamydia, gonorrhoea and/or syphilis in four community-based pilots through targeted interventions in Croatia, Italy and Poland and the Spring European Testing Week since community settings are key in detecting new infections and reaching key populations. METHODS: Pilots led by local INTEGRATE partners prioritised testing for other infections or key populations. The Croatian pilot expanded testing for men who have sex with men to syphilis, chlamydia and gonorrhoea. Italian partners implemented a HIV and HCV testing/information event at a migrant centre. A second Italian pilot tested migrants for HIV and HCV through outreach and a low-threshold service for people who use drugs. Polish partners tested for HIV, HCV and syphilis among people who inject drugs in unstable housing via a mobile van. Pilots monitored the number of individuals tested for each infection and reactive results. The pilot Spring European Testing Week from 18 to 25 May 2018 was an INTEGRATE-driven initiative to create more testing awareness and opportunities throughout Europe. RESULTS: The Croatian pilot found a high prevalence for each syphilis, chlamydia and gonorrhoea respectively, 2.1%, 12.4% and 6.7%. The Italian migrant centre pilot found low proportions who were previously tested for HIV (24%) or HCV (11%) and the second Italian pilot found an HCV prevalence of 6.2%, with low proportions previously tested for HIV (33%) or HCV (31%). The Polish pilot found rates of being previously tested for HIV, HCV and syphilis at 39%, 37%, and 38%, respectively. Results from the Spring European Testing Week pilot showed it was acceptable with increased integrated testing, from 50% in 2018 to 71% in 2019 in participants. CONCLUSIONS: Results show that integrated testing is feasible and effective in community settings, in reaching key populations and minimising missed testing opportunities, and the pilots made feasible because of the European collaboration and funding. For sustainability and expansion of integrated community testing across Europe, local government investment in legislation, financial and structural support are crucial.

RESUMO

BACKGROUND: Country level policies and practices of testing and care for HIV, viral hepatitis and sexually transmitted infections are lagging behind European recommendations on integration across diseases. Building on previous experiences and evidence, the INTEGRATE Joint Action arranged four national stakeholder meetings. The aim was to foster cross-disciplinary and cross-disease collaborations at national level as a vehicle for strengthened integration of testing and care services. This article presents the methodology and discusses main outcomes and recommendations of these meetings. METHODS: Local partners in Croatia, Italy, Lithuania and Poland oversaw the planning, agenda development and identification of key persons to invite to ensure that meetings addressed main challenges and issues of the respective countries. Invited national stakeholders represented policy and public health institutions, clinical settings, testing sites and community organisations. National experts and experts from other European countries were invited as speakers and facilitators. Main topic discussed was how to increase integration across HIV, viral hepatitis and sexually transmitted infections in testing and care policies and practice; tuberculosis was also addressed in Lithuania and Italy. RESULTS: The agendas reflected national contexts and the meetings provided a forum to engage stakeholders knowledgeable of the national prevention, testing and care systems in interaction with international experts who shared experiences of the steps needed to achieve integration in policies and practice. The evaluations showed that participants found meetings relevant, important and beneficial for furthering integration. Of the respondents 78% agreed or strongly agreed that there was a good representation of relevant national stakeholders, and 78% that decision/action points were made on how to move the agenda forward. The importance of securing participation from high level national policy makers was highlighted. Outcomes were nationally tailored recommendations on integrated policies and strategies, diversification of testing strategies, stigma and discrimination, key populations, cost effectiveness, surveillance and funding. CONCLUSIONS: Shifting from single to multi-disease approaches require collaboration among a broad range of actors and national multi-stakeholder meetings have proven excellent to kick-start this. Face-to-face meetings of key stakeholders represent a unique opportunity to share cross-sectoral perspectives and experiences, identify gaps in national policies and practices and agree on required next steps.

RESUMO

Background: Pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) have been increasingly available in Europe. Due to the high burden of HIV in key populations, these could benefit from their use. In 2016, in Portugal, an open, non-interval, prospective cohort study was established in a network of 26 community-based voluntary HIV/STI counseling and testing centers. Data collected included questions on PEP and PrEP knowledge and use. We aimed to estimate the proportion of PEP and PrEP knowledge and its use among key populations, visiting the centers between 2016 and 2019. Method and results: Individuals who self-identify as being among at least one key population for HIV, men who have sex with men (MSM), people who inject drugs (PWID), sex workers (SW), migrants, and male-to-female transgender individuals (MTF), responded to questions on PEP and PrEP knowledge and use while waiting for their test results between 2016 and 2019 (n = 12,893 for PEP; n = 10,973 for PrEP). Reported knowledge was low in all key populations for both tools: 15.7% of respondents reported knowing about PEP and 10.9% about PrEP over the course of 4 years. PEP was used by 1.8% and PrEP by 0.4% of the respondents, MSM being 88.9% of PrEP users, and 52.8% of PEP users. Multivariate logistic regression showed multiple factors associated with knowing the tools, including age, education, country of birth, gender, year of test, having a reactive HIV test in the same visit, reporting an STI or condomless sex in the last 12 months, and identifying with being MSM or SW. Conclusions: Knowledge and use of PEP and PrEP remain low among key populations in Portugal. The need remains to increase knowledge and use among those at risk for HIV infection.

RESUMO

We present preliminary results of a coronavirus disease (COVID-19) impact assessment on testing for HIV, viral hepatitis and sexually transmitted infections in the WHO European Region. We analyse 98 responses from secondary care (n = 36), community testing sites (n = 52) and national level (n = 10). Compared to pre-COVID-19, 95% of respondents report decreased testing volumes during March-May and 58% during June-August 2020. Reasons for decreases and mitigation measures were analysed.

RESUMO

Composting is a process recommended as a way to recycle the organic part of the solid waste in which several micro and macroorganisms act as decomposers of the organic matter, in a process that takes around 120 days and faces roughly three different phases. Because we do not know the community of arthropods associated with the compost produced in one of the biggest landfills placed in Brazil, here we collected and identified the community of arthropods present in each phase of the organic compost. Our hypothesis is that the abundance and diversity of arthropods are different within each phase of the compost and we hope to find particular groups of arthropods that can be used as indicator of specific phases. In total, we identified the taxa of 1204 arthropods (insects, arachnidan and diplopods). We found that diversity and abundancy of arthropods were indeed different for each maturation phase of the compost, but we did not find families that are good indicators of each phase. In addition, to be certain about the safety of the compost produced, we investigated the presence of microorganisms in the final product and we found considerable levels of Escherichia coli and Enterococcus faecalis in some samples. Finally, we argue that the presence of these macro and microorganisms during the process may be beneficial or harmful. Since their presence decreased greatly by the end of the process, we acknowledge that composting works efficiently as a way to recycle the organic part of the waste generated in Brazil.

RESUMO

O mosquito Aedes albopictus possui ampla distribuição em regiões tropicais, bem como nos países de clima temperado e tem sido apontado pela literatura científica como importante para a saúde pública. Observa-se a carência de estudos acerca da infestação, dispersão e a associação da espécie com o grau de urbanização, criadouros, tipos de imóveis e sazonalidade. Este estudo teve como objetivos, dentre outros, analisar a evolução da infestação por A. albopictus ao longo de um gradiente de urbanização. O estudo teve como referência geográfica o município de Chapecó (SC). Para avaliar a dispersão e a flutuação populacional foi criado um gradiente de urbanização. Para avaliar a tendência da infestação em cada região no período, foram utilizadas análises de regressão linear. A infestação pelo mosquito foi maior nas regiões periurbanas e rurais e menor nas regiões mais urbanizadas. Os resultados encontrados são relevantes no planejamento e na implantação de ações de prevenção das arboviroses transmitidas.


Aedes albopictus mosquito is widely distributed in tropical regions, as well as in temperate countries, and has been identified by the scientific literature as important to public health. There is a lack of studies on infestation, dispersion and the species association with the level of urbanization, breeding sites, types of property and seasonality. This study aimed to analyze the evolution of A. albopictus infestation along an urbanization gradient. The geographical reference of this study was the municipality of Chapecó, State of Santa Catariana. To assess dispersion and population fluctuation an urbanization gradient was created. Linear regression analysis was applied to evaluate the trend of infestation in each region in the study period. Mosquito infestation was higher in peri-urban and rural regions, and lower in more urbanized regions. The results are relevant for planning and implementing prevention actions for transmitted arbovirus diseases.

RESUMO

BACKGROUND: Migrants from high endemic countries accounted for 18% of newly diagnosed HIV infections in Europe in 2017. Knowledge on the link between HIV risk and post-migration travels and their impact on HIV acquisition is scarce, but critical to inform prevention. This study aims to explore risky sexual behaviour and HIV-acquisition among sub-Saharan African migrants, and to assess post-migration mobility as a determinant of sexual risk behaviour. METHODS: Data from two cross-sectional bio-behavioural surveys to assess HIV-prevalence conducted in Lisbon and Antwerp were analysed to explore migration-related characteristics, travel patterns, and sexual risk taking in the host country and abroad. Bi- and multivariate associations were estimated through adjusted odds ratios and 95% confidence intervals; multivariable logistic regression determined factors associated with condomless sexual intercourse. RESULTS: Among N = 1508 participants above 18 years (58% males), 68% travelled post-migration (49.2% reported intercourse abroad). The overall proportion of condomless sex at last sexual intercourse was high (68.1%). The odds of condomless sex in the host country was five times higher when the last sexual intercourse abroad was also condomless [OR:5.32; 95%CI:2.98-9.25]. About half of the travellers reported concurrency, i.e. a regular partner in the host country while having other sexual partners abroad. Almost three percent of the participants reported being HIV+, but 5% had a reactive HIV test-result, with similar proportions among travellers and non-travellers. Also, among the n = 75 participants with reactive HIV test-results, condomless sex occurred (n = 40) and was associated with mobility. CONCLUSIONS: Sub-Saharan African migrants are mobile and engage in sexual risk behaviours in the countries of residence and while travelling, increasing risk of post-migration HIV-acquisition. A transnational perspective on HIV prevention and sexual health promotion is needed for effectively reducing migrants' HIV risk related to their mobility.

RESUMO

This study identified patterns of sexual risk behavior among a sub-Saharan African migrant (SAM) population in Portugal and examined its associations with human immunodeficiency virus (HIV) prevalence, sociodemographics, use of sexual health services, and HIV testing. A cross-sectional biobehavioral survey was conducted with a venue-based sample of 790 SAMs. Data were collected using questionnaires and rapid HIV tests. Cluster analysis identified five subgroups with differing levels of HIV infection (2.5% to 11.3%). In Cluster 1, most participants reported sexual abstinence over the past year and the remaining used condoms consistently; this cluster had the highest HIV prevalence (11.3%). In Cluster 2, most reported one sexual partner and all reported unprotected sex; all HIV-positive participants in this cluster were unaware of their HIV-positive status. In Clusters 3 and 4, most had four or more partners, yet all used condoms. In Cluster 3, 56.5% reported both regular and occasional partners. In Cluster 4, 74% had only occasional partners; all engaged in commercial sex. In Cluster 5, all reported four or more partners and condomless sex. In all subgroups we found low rates of HIV testing and high unawareness of HIV serostatus. Targeted prevention interventions are needed to reduce unprotected sexual relations and undiagnosed infection, as well as improve linkage to sexual health services.

RESUMO

Globally, high rates (and in the WHO European region an increasing prevalence) of co-infection with tuberculosis and HIV and HIV and hepatitis C virus exist. In eastern European and central Asian countries, the tuberculosis, HIV, and viral hepatitis programmes, including diagnostic services, are separate vertical structures. In this Personal View, we consider underlying reasons for the poor integration for these diseases, particularly in the WHO European region, and how to address this with an initial focus on diagnostic services. In part, this low integration has reflected different diagnostic development histories, global funding sources, and sample types used for diagnosis (eg, typically sputum for tuberculosis and blood for HIV and hepatitis C). Cooperation between services improved as patients with tuberculosis needed routine testing for HIV and vice versa, but financial, infection control, and logistical barriers remain. Multidisease diagnostic platforms exist, but to be used optimally, appropriate staff training and sensible understanding of different laboratory and infection control risks needs rapid implementation. Technically these ideas are all feasible. Poor coordination between these vertical systems remains unhelpful. There is a need to increase political and operational integration of diagnostic and treatment services and bring them closer to patients.

RESUMO

Sub-Saharan African migrants (SSAMs) have been disproportionately affected by infectious disease burden. We aimed to identify correlates of HIV, past sexually transmitted infection (STI) and past Tuberculosis infection (TB), as well as examine HIV seropositivity unawareness and testing history among SSAMs. A venue-based sample of 790 SSAMs completed a cross-sectional biobehavioral survey on sexual practices, HIV testing and self-reported infectious diseases; an HIV rapid test was offered. Overall, 5.4% of participants were HIV-positive and 16.7% reported a past STI. Odds of being HIV positive or having a past STI were higher among participants with low socioeconomic status and who experienced violence from a partner. Increased odds of having a past STI were also found among long-term migrants and those who reported sexual risk behaviors. In total, 4.1% of participants had TB in the past; these were more likely male and HIV positive. Unawareness of HIV-positive status was notably high (35%). Half of the participants had never been tested for HIV before, including over a third of those who had STI or TB in the past. Efforts are needed to reduce missed opportunities for HIV/STIs prevention and uptake of HIV testing among SSAMs through more integrated care, while addressing social determinants of infectious diseases.
