Palliative care progress in Benin: a situation analysis using the WHO development indicators.

CONTEXT: Palliative care (PC) in most African countries remains under-assessed. Benin has piloted the implementation of a set of indicators proposed by the WHO to measure PC development. OBJECTIVES: To examine the current status of PC in Benin. METHODS: A workshop with stakeholders was organized to assess the WHO indicators in the Beninese context. Indicators were rated based on relevance and feasibility, data sources were agreed upon, and a survey was adapted. Data were collected between March and May 2023. RESULTS: There is emerging community involvement in PC through the presence of patients' rights promoters, as well as a political commitment expressed in the National PC strategy, the inclusion of PC services in the list of basic health services, and an assigned national authority -within the Ministry of Health-responsible for PC. Although no PC-oriented research has been documented, the celebration of the National PC Conference represents the first step to ground PC delivery in evidence. The reported annual consumption of opioids is 0.18 (ME) milligrams per capita, 34% of healthcare establishments have essential medicines for pain and PC, and 16.5% of patients with palliative needs have access to oral morphine. To date, no medical or paramedical schools offer PC training, and there is no official specialization in palliative medicine for doctors. PC is provided by 11 specialist teams (0.08/100,000 inhabitants), none of which provides pediatric care. CONCLUSION: Despite growing political, professional, and community commitments to palliative care, there are challenges in education, research, essential medicines, and access to PC services.

Family Nursing Care during the Transition to Parenthood: A Scoping Review.

BACKGROUND: Family-centered care places the family at the core of care, with family nurses playing a pivotal role in supporting and guiding members through pregnancy and the transition to parenthood and acknowledging the significant adjustments during these phases. AIM: To map the evidence concerning family nurses' care for families during the transition to parenthood. METHOD: The scoping review followed the Joanna Briggs Institute (JBI) methodology, focusing on family-centered care during pregnancy adaptation and the initial months of parenthood. Using a PCC (population, concept, and context) strategy, the research covered various databases: Scopus; Web of Science; and CINAHL Complete, MedLine Complete, and MedicLatina by EBSCOhost. RESULTS: A Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for Scoping Reviews (PRISMA-ScR) flow diagram was used to present the results. Eighteen articles were included, mainly from the Middle East and Europe, including cross-sectional studies and reviews. Key findings addressed the transitioning process to parenthood, the impact of family characteristics, and the role of family nurses in enhancing these processes. CONCLUSION: Home care is considered vital during this transition. Family nursing should concentrate on both individuals and the parental subsystem, addressing social determinants equitably. Through these efforts, they empower families to establish an optimal environment for children's development.

Epidemiological Assessment of a Pediatric Palliative Care Clinic at a Brazilian Quaternary Hospital: 20 Years of Experience.

Background: The pediatric palliative care (PPC) sets up an interdisciplinary approach of chronic complex diseases throughout birth to adolescence. It encompasses countless contrasts in development and diagnosis scopes, which make this area a challenge to nonpediatric practitioners. Objective: We sought to assess the most prevalent diseases in follow-up of the PPC team. Methods: We analyzed the medical records of PPC clinic during the years 2001 and 2021 and the diagnosis of outpatients. We established a parallel with the world scientific literature concerning the epidemiology of PPC. Results: The most prevalent diseases were epidermolysis bullosa (36.9%), followed by neurological Inherited Errors of Metabolism (IEM) diseases (19.0%), IEM diseases (14.3%), dysmorphological and chromosomal disorders (8.5%), skeletal disorders mainly osteogenesis imperfecta (6.9%), and liver transplantation conditions (5.5%) (p < 0.001). The less frequent conditions were external causes, such as neonatal insults or traffic accidents (2.8%), cancer (1.7%), congenital cardiopathies (1.4%), congenital infectious diseases (1.1%), gastrointestinal and hepatic conditions (0.8%), and rheumatological conditions (0.3%). The patients were older at diagnosis (6.9 years) and at PPC referral (13.2 years) than patients with epidermolysis bullosa and skeletal disorders and dysmorphological and chromosomal disorders were younger on referral. Conclusion: There are a lot of complex chronic conditions which could benefit from palliative care in pediatric setting. However, epidemiological and symptomatological assessment of the health service is necessary to provide an appropriate care to the country's reality.

Rising Incidence of Sporothrix brasiliensis Infections, Curitiba, Brazil, 2011-2022.

Zoonotic outbreaks of sporotrichosis are increasing in Brazil. We examined and described the emergence of cat-transmitted sporotrichosis (CTS) caused by the fungal pathogen Sporothrix brasiliensis. We calculated incidence and mapped geographic distribution of cases in Curitiba, Brazil, by reviewing medical records from 216 sporotrichosis cases diagnosed during 2011-May 2022. Proven sporotrichosis was established in 84 (39%) patients and probable sporotrichosis in 132 (61%). Incidence increased from 0.3 cases/100,000 outpatient visit-years in 2011 to 21.4 cases/100,000 outpatient visit-years in 2021; of the 216 cases, 58% (n = 126) were diagnosed during 2019-2021. The main clinical form of sporotrichosis was lymphocutaneous (63%), followed by localized cutaneous (24%), ocular (10%), multisite infections (3%), and cutaneous disseminated (<0.5%). Since the first report of CTS in Curitiba in 2011, sporotrichosis has increased substantially, indicating continuous disease transmission. Clinician and public awareness of CTS and efforts to prevent transmission are needed.

Spread of Sporothrix spp. through respiratory droplets from infected cats: A potential route of transmission.

Cases of cat-transmitted sporotrichosis in Brazil have increased in recent years. We collected respiratory secretions expelled while sneezing from 28 cats diagnosed with sporotrichosis. We identified the presence of Sporothrix spp. in respiratory droplets expelled in the sneeze of infected cats. The results raise concerns about a new transmission route for cat-transmitted sporotrichosis. Physicians who diagnose and treat human cases of sporotrichosis should be aware of this potential new transmission method to improve clinical suspicion. Approximately half of patients with granulomatous conjunctival sporotrichosis did not report experiencing traumatic injury from cats.

Cat-transmitted sporotrichosis is a zoonosis in geographic expansion from Brazil to other Latin American countries and is considered a public health problem. Data suggest that transmission can occur through the sneeze of an infected cat. The One Health approach is necessary to control the disease.

COVID-19 cross-sectional study in Maricá, Brazil: The impact of vaccination coverage on viral incidence.

Population surveillance in COVID-19 Pandemic is crucial to follow up the pace of disease and its related immunological status. Here we present a cross-sectional study done in Maricá, a seaside town close to the city of Rio de Janeiro, Brazil. Three rounds of study sampling, enrolling a total of 1134 subjects, were performed during May to August 2021. Here we show that the number of individuals carrying detectable IgG antibodies and the neutralizing antibody (NAb) levels were greater in vaccinated groups compared to unvaccinated ones, highlighting the importance of vaccination to attain noticeable levels of populational immunity against SARS-CoV-2. Moreover, we found a decreased incidence of COVID-19 throughout the study, clearly correlated with the level of vaccinated individuals as well as the proportion of individuals with detectable levels of IgG anti-SARS-CoV-2 and NAb. The observed drop occurred even during the introduction of the Delta variant in Maricá, what suggests that the vaccination slowed down the widespread transmission of this variant. Overall, our data clearly support the use of vaccines to drop the incidence associated to SARS-CoV-2.

Nursing knowledge of people with paresis of voluntary muscles: a living scoping review protocol.

OBJECTIVE: This review aims to continuously map the nursing knowledge about people with paresis of voluntary muscles in any context of care. INTRODUCTION: Muscle paresis is a condition that significantly impacts quality of life. Nurses have a crucial role in managing this condition, particularly paresis of voluntary movement muscles. However, nursing knowledge about patients with paresis of voluntary muscles is dispersed, hampering the integration of evidence within the structure of information systems. Mapping how the nursing process components are identified is the first step in creating a Nursing Clinical Information Model for this condition, capable of integrating evidence into information systems. INCLUSION CRITERIA: This scoping review will consider studies focusing on the nursing process regarding people with paresis of voluntary muscles in all care contexts. The review will include quantitative, qualitative, and mixed-methods study designs, systematic reviews, clinical guidelines, dissertations, and theses. METHODS: The review process will follow JBI's scoping review guidance, as well as the Cochrane Collaboration's guidance on living reviews. Screening of new literature will be performed regularly, with the review being updated according to new findings. The search strategy will map published and unpublished studies. The databases to be searched will include MEDLINE, CINAHL, Scopus, JBI Evidence Synthesis , and the Cochrane Central Register of Controlled Trials. Searches for unpublished studies will include OpenGrey and Repositorios Científicos de Acesso Aberto de Portugal. Studies published in English and Portuguese from 1975 will be considered for inclusion. REGISTRATION: Open Science Framework: https://osf.io/d7c9g/.

Nursing knowledge on skin ulcer healing: a living scoping review protocol.

OBJECTIVE: This review aims to continuously map the nursing knowledge on skin ulcer healing in any context of care. INTRODUCTION: Chronic wounds are an increasing concern for society and health care providers. Pressure ulcers and venous ulcers, among others, have devastating effects on morbidity and quality of life and require a systematic approach. The nursing process is an important method that allows a better organization and overall care quality for a systematic and continuous professional approach to nursing management of skin ulcers. The integration of this nursing knowledge in informatics systems creates an opportunity to embed decision-support models in clinical activity, promoting evidence-based practice. INCLUSION CRITERIA: This scoping review will consider articles on nursing data, diagnosis, interventions, and outcomes focused on people with skin ulcers in all contexts of care. This review will include quantitative, qualitative, and mixed methods study designs as well as systematic reviews and dissertations. METHODS: JBI's scoping review guidance, as well as the Cochrane Collaboration's guidance on living reviews, will be followed to meet the review's objective. Screening of new literature will be performed regularly, with the review updated according to new findings. The search strategy will map published and unpublished studies. The databases to be searched include MEDLINE, CINAHL, Scopus, JBI Evidence Synthesis, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and PEDro. Searches for unpublished studies will include OpenGrey and Repositórios Científicos de Acesso Aberto de Portugal. Studies published in English and Portuguese since 2010 will be considered for inclusion. SCOPING REVIEW PROTOCOL REGISTRATION: Open Science Framework: https://osf.io/f6s4e/.

Paediatric to adult healthcare transition in resource-limited settings: a narrative review.

Background: Ageing into adulthood is challenging at baseline, and doing so with a chronic disease can add increased stress and vulnerability. Worldwide, a substantial care gap exists as children transition from care in a paediatric to adult setting. There is no current consensus on safe and equitable healthcare transition (HCT) for patients with chronic disease in resource-denied settings. Much of the existing literature is specific to HIV care. The objective of this narrative review was to summarise current literature related to adolescent HCT not associated with HIV, in low-income and middle-income countries (LMICs) and other resource-denied settings, in order to inform equitable health policy strategies. Methods: A literature search was performed using defined search terms in PubMed and Cumulative Index to Nursing and Allied Health Literature databases to identify all peer-reviewed studies published until January 2020, pertaining to paediatric to adult HCT for adolescents and young adults with chronic disease in resource-denied settings. Following deduplication, 1111 studies were screened and reviewed by two independent reviewers, of which 10 studies met the inclusion criteria. Resulting studies were included in thematic analysis and narrative synthesis. Results: Twelve subthemes emerged, leading to recommendations which support equitable and age-appropriate adolescent care. Recommendations include (1) improvement of community health education and resilience tools for puberty, reproductive health and mental health comorbidities; (2) strengthening of health systems to create individualised adolescent-responsive policy; (3) incorporation of social and financial resources in the healthcare setting; and (4) formalisation of institution-wide procedures to address community-identified barriers to successful transition. Conclusion: Limitations of existing evidence relate to the paucity of formal policy for paediatric to adult transition in LMICs for patients with childhood-onset conditions, in the absence of a diagnosis of HIV. With a rise in successful treatments for paediatric-onset chronic disease, adolescent health and transition programmes are needed to guide effective health policy and risk reduction for adolescents in resource-denied settings.

Survey of ticks and tick-borne agents in maned wolves (Chrysocyon brachyurus) from a natural landscape in Brazil.

This study evaluated ticks and tick-borne agents in 104 captures of the maned wolf Chrysocyon brachyurus (50 different individuals and 54 recaptures) in the Serra da Canastra National Park (SCNP), a Cerrado preserved area in southeastern Brazil, from 2005 to 2012. From the 104 capture events, a total of 1,206 ticks were collected on 94 occasions (90.4 %), and identified into five species: Amblyomma tigrinum (77.3 % of all collected ticks), Amblyomma sculptum (16.6 %), Amblyomma ovale (0.1 %), Amblyomma brasiliense (0.1 %), Rhipicephalus microplus (0.1 %), and Amblyomma spp. larvae (5.8 %). Molecular analyses of A. tigrinum adult ticks revealed the presence of 'Candidatus Rickettsia andeanae', Rickettsia parkeri sensu stricto, two different haplotypes of 'Ca. Midichloria sp.', and a Hepatozoon canis haplotype. Molecular analyses of maned wolf blood samples revealed two distinct haplotypes of Hepatozoon spp., one identical to the H. canis genotype that was detected in the A. tigrinum ticks, and a Hepatozoon americanum-like haplotype. None tick or blood samples yielded amplicons through PCR assays targeting the genera Ehrlichia, Anaplasma, Babesia, Rangelia, Cytauxzoon, and Theileria. Maned wolf serum samples were tested by immunofluorescence assay against antigens of five Rickettsia species (R. parkeri, R. rickettsii, R. amblyommatis, R. rhipicephali, and R. bellii) and Ehrlichia canis. Among 78 serum samples (45 captures plus 33 recaptures), 74 (95 %) were reactive to at least one Rickettsia species, with R. parkeri eliciting the highest endpoint titers. Some maned wolves that were recaptured during the study were shown to seroconvert to R. parkeri. Serum-reactiveness to E. canis was detected in 36 % (16/45) maned wolves. During the study, general clinical signs of tick-borne diseases were not found in any of the captured animals, indicating that they were under a good health status in the SCNP, despite of been exposed to ticks (mostly A. tigrinum) and some tick-borne agents (Rickettsia, Hepatozoon, Ehrlichia). The results of the present study might represent baseline data for the conservation of the maned wolf in its natural habitat, which should be used to interpret further studies about ticks and tick-borne diseases in maned wolves within human-modified landscapes.

Life cycle of Ixodes schulzei (Acari: Ixodidae) in the laboratory, and demonstration of reproduction by parthenogenesis.

Ixodes schulzei is an ixodid tick that parasitizes Cricetidae rodents, chiefly the South American water rat, Nectomys squamipes, in Brazil and Argentina. In the present study, we evaluated the life cycle of I. schulzei by exposing larvae and nymphs to feed on two rodent species, N. squamipes and Calomys callosus (large vesper mouse),while adult ticks were exposed to feed on N. squamipes. Off-host developmental periods were observed in an incubator at 27 °C, 95% relative humidity, and 0:24 (light:dark) regimen. Larvae and nymphs successfully fed on either C. callosus or N. squamipes. Mean larval and nymphal feeding periods were 8.8 and 8.7 days on N. squamipes and 8.5 and 9.7 days on C. callosus. The majority of engorged larvae (79.0-80.8%) and nymphs (67.0-86.0%) successfully molted to nymphs and adults, respectively. Mean premolt periods were 11.5-11.7 days for engorged larvae and 22.5-23.7 days for engorged nymphs. Only adult females emerged from engorged nymphs, regardless of host species, i.e., none of 120 engorged nymphs molted to male. Around 18% of the unfed females presented teratologies compatible with the metagynander type of gynandromorphism. Ixodes schulzei adult females successfully fed (mean feeding period, 9.4 days), oviposited, and presented high reproductive performance (high engorged weight, egg mass weight, and % egg mass hatching), in the absence of male ticks. Our results showed that I. schulzei successfully reproduces by parthenogenesis, and corroborate field data that indicate N. squamipes as the most important host for this tick species. The male of I. schulzei remains unknown.

Quality control and immunomodulatory potential for clinical-grade equine bone marrow-derived mesenchymal stromal cells and conditioned medium.

This study aimed to assess the safety and reproducibility of cell therapy for its use in clinical practice. We performed immunophenotypic characterization of equine bone marrow-derived mesenchymal stromal cells (BMMSCs) by flow cytometry using CD90, CD19, CD14, CD105, CD45, and HLA-DR markers (n = 4); GTG banding cytogenetic analysis (n = 3); and microbiological quality control (n = 4). The immunomodulatory potentials of BMMSCs (n = 4) and its conditioned medium (CM, n = 3) were investigated by in vitro lymphocyte inhibition assay using phytohemagglutinin (PHA)-stimulated peripheral blood mononuclear cells (PBMCs). BMMSCs populations isolated from all animals showed high expression of CD90 and CD105, and low expression of CD19, CD4, CD45, and HLA-DR. Of the 60 metaphases analyzed, 5% presented aneuploidy on random chromosomes and no contamination was found based on microbiological analyses. Both treatments significantly inhibited lymphocyte proliferation (> 50%), compared with PHA-stimulated PBMCs (p < 0.0001). These promising results for BMMSCs and CM justify their potential as a therapeutic approach for inflammatory diseases. The techniques used in this study were effective in assessing the quality and determining the minimum criteria for the clinical use of BMMSCs in veterinary medicine.

Seroprevalence and factors associated with Human Immunodeficiency virus, Human T lymphotropic virus and Hepatitis B/C infections in parturient women of Salvador - Bahia, Brazil

Abstract Background The heterogeneity in detection rates of Human immunodeficiency virus, (HIV), Human T lymphotropic virus (HTLV) and Hepatitis B and C infections among pregnant women and the continuous exposure to risk factors limits the adoption of preventive and control actions. Objective To evaluate the HIV, HTLV, Hepatitis B and C seroprevalence rates, and associated risk factors in parturient women in Salvador, Brazil. Methods This was a cross-sectional study in 2099 parturient women attended in two public maternity hospitals in Salvador, Brazil. One blood sample was drawn for serological screening and socio-demographic, obstetric and clinical data were collected. Results HIV seroprevalence rate was 1.5% (of which 0.6% were new cases); seroprevalence rates for HTLV, HBV, and HCV were 0.4%, 0.4%, and 0.1%, respectively. Univariate analysis showed a significant association between socio-demographic and behavioral factors with retroviral infections, while viral hepatitis was mainly associated with parenteral exposure. In a multivariate analysis, multiple sexual partners (OR 3.3; 95% CI: 1.1-9.2), history of sexual/domestic violence (OR 2.8; 95% CI: 1.1-6.9), syphilis co-infection (OR 2.6; 95% CI: 1.0-6.9), use of alcohol or drugs (OR 2.5; 95% CI: 1.2-5.5), and low schooling level (OR 2.3; 95% CI: 1.1-4.9) were independent risk factors for HIV infection. History of stillbirth and low birth weight infants was significantly associated with HTLV positive status, showing a negative impact on gestation. Conclusions The seroprevalence rates for HIV, HCV, HBV, and HTLV were similar to that found in previous studies in other Brazilian regions. The high individual, socioeconomic, and social vulnerability detected in seropositive parturient women indicates the need to improve coverage and effectiveveness of STDs control with prevention, detection and monitoring strategies, focusing in pregnant women exposed to high biopsychosocial risk.

Canine Visceral Leishmaniasis in São Paulo, Brazil, the Most Populous City of South America: Isolation, Molecular Diagnosis, and Phylogenetic Inferences.

Background and Objectives: Canine visceral leishmaniasis affects dogs, the main urban reservoirs, which favor the transmission and expansion of this zoonotic disease in areas with high anthropization process and human density. We investigated the occurence of Leishmania infatum based in molecular diagnosis, and phylogenetic analysis of isolates obtained from dogs in metropolitan region of São Paulo. Methods: A total of 201 dogs were tested by parasitological and molecular diagnosis. Phylogenetic analysis based sequences from SSUrDNA and gGAPDH genes were performed. Results: The parasitological diagnosis revealed 5% (10/201) of positivity, and the sequences obtained from seven isolates were clustered with L. infantum in phylogentic analysis based on SSUrDNA and gGAPDH genes. A total of 24.9% (50/201) of dogs were positive in molecular diagnosis based on cathepsin L-like marker. Interpretation and Conclusion: According to this study, it is necessary to implement a surveillance policy of visceral leishmaniasis, intensifying the actions of diagnosis, prevention, and control of this zoonosis.

Infrared Thermography Applied to Monitoring Musculoskeletal Adaptation to Training in Thoroughbred Race Horses.

Infrared thermography has been used to help in diagnosing lameness. It is hypothesized that, if used in a routine basis, it could help in understanding musculoskeletal modifications during race training. This study aimed to evaluate thermal variation in the musculoskeletal regions of young Thoroughbred (TB) horses during their initial months of race training. Thermographic examinations were performed once every 2 weeks on 16 (10 male, 6 female) two-year-old TB racehorses, from arrival to the racetrack in June 2016, until January 2017, for a total of 16 evaluations. Thermographic imaging was performed using the appropriate protocol. Temperature (°C) was measured at the dorsal and palmar/plantar aspects of specific regions of interest (fetlock, metacarpal, metatarsal, carpal, tarsal, thoracolumbar, sacroiliac spine, and both hips). Initially, we found a thermal balance and all regions demonstrated a positive correlation with one another. However, a significant difference was noted between the left and right sides as training progressed. Four horses were withdrawn from the study after 50% of evaluations because of metacarpal conditions associated with training. Thermographic examination revealed changes before the clinical manifestation of these conditions. In conclusion, this study demonstrated that infrared thermography is an image technique that can facilitate understanding of musculoskeletal system modifications to race training and should be further investigated as a predictive tool to anticipate the occurrence of lesions.

Exploring Leishmania infantum cathepsin as a new molecular marker for phylogenetic relationships and visceral leishmaniasis diagnosis.

BACKGROUND: Leishmania infantum, the etiological agent of visceral leishmaniasis, is a neglected zoonosis that requires validation and standardization of satisfactory diagnostic methodologies. Thus, the aim of the present study was to evaluate the effectiveness of cathepsin L-like protease as a target for making molecular diagnoses and as a phylogenetic marker enabling to understand the intraspecies variations and evolutionary history of L. infantum in Brazil. METHODS: We used 44 isolates of L. infantum. The cathepsin L-like gene fragments were amplified, sequenced, manually aligned and analyzed using inference methods. The sequences generated were used to search and design oligonucleotide primers to be used in reactions specific to the target parasite. RESULTS: The cathepsin L-like gene did not show any intraspecies variability among the isolates analyzed. The pair of primers proposed amplified the target deoxyribonucleic acid (DNA) of L. infantum isolates and were effective for DNA amplification at concentrations of as low as 10- 11 ng/µl. The proposed marker did not present cross-reactions with other hemoparasites. When used for making the diagnosis in a panel of clinical samples from dogs, a positivity rate of 49.03% (102/208) was obtained, versus 14.42% (30/208) for a ribosomal internal transcribed spacer (ITS) marker. In samples from sandflies, the rate was 6.25% and from humans, 14.28%. CONCLUSIONS: The results described in this work allow us to infer that CatLeish-PCR is a sensitive and specific marker for use in diagnostic trials of L. infantum and in clinical and epidemiological surveys.

Short Communication: Getting Older with HIV: Increasing Frequency of Comorbidities and Polypharmacy in Brazilian HIV Patients.

Life expectancy of HIV patients has increased over time. Older HIV patients have a higher frequency of noncommunicable diseases (NCD) than general population, and require multiple treatments. The main objective is to evaluate the changes in frequency of NCD and polypharmacy in HIV patients of three referral centers in Salvador and São Paulo. We compared the frequency of NCD and use of concomitant treatments in HIV patients, >50 years, in three Brazilian referral centers (São Paulo and Salvador). Data on sociodemographic characteristics, HIV therapy, CD4 count and viral load measurements, and frequency of NCD at baseline and last medical visit were recorded. We evaluated 451 patients, 128 in Salvador and 323 in São Paulo. Mean age was 57.9 ± 6.9 years. Mean baseline CD4 count was 199 ± 169. At baseline, dyslipidemia (4.0%) was the most frequent comorbidity, but at last visit we detected a high frequency of diabetes (14.9%), dyslipidemia (26.7%), osteoporosis (6.7%), stroke (4.4%), and malignancies (3.1%). Use of concomitant drugs for treatment of NCD increased significantly between first and last visit, especially antihypertensive, lipids lowering, and diabetes drugs. Aging in HIV patients in Brazil is characterized by an increasing incidence of NCD and polypharmacy.

Seroepidemiology of hepatitis B in individuals born between 1945-1985 on a Brazilian regional metropolis / Soroepidemiologia da hepatite B em indivíduos nascidos entre 1945-1985 em uma metrópole regional Brasileira

Background: hepatitis B prevalence can be influenced by social/cultural behavior and the Baby Boomer (BB) generation(1945-1964) may have been more susceptible to this infection. Objectives: We investigated the seroprevalence of markers for HBV infection and vaccination and its association with main risk factors. Methodology: a random sample of individuals aged 30-70 years old in a public clinical laboratory from a metropolitan area of Bahia/Brazil were tested for HBsAg/Total Anti-HBc/Anti-HBs/Anti-HBc-IgM and a socio-demographic questionnaire was applied. Results: of the650 participants, 349 were 51-70 yo (BB) and 301 were non-BB. The prevalences were HBsAg (2.3%), Total Anti-HBc (17.1%) and Anti-HBs (27.4%). Anti-HBcIgM (2.7%) was performed in 112 participants sera who had contact/infection with HBV. The laboratory profiles were characterized as susceptibility (68%), vaccine response (14.8%) and contact/infection with HBV (17.2%). BB participants were more susceptible and less vaccinated than non-BB. The higher frequency of contact/infection status was observed in the BB generation. Statistically significant differences were found for the contact/infection status in males(50,9%) illicit drug use (11,6%), syringe/needle sharing (7,1%), and blood transfusion (10,7%). Non-BB with contact/ infection profile reported more tattoo/piercing and BB reported higher use of glass syringes. Conclusion: the majority of the study population was susceptible to infection but participants older than 50 years showed both, a higher frequency of this profile and also a higher frequency of contact/infection status, thus suggesting the need for greater health care attention for this age group.

Introdução: a prevalência de hepatite B pode ser influenciada pelo comportamento sociocultural e a geração Baby Boomer (BB) (1945-1964) pode ter sido mais suscetível a esta infecção. Objetivos: Investigar a soroprevalência de marcadores para a infecção pelo VHB e resposta vacinal e associação com fatores de risco. Metodologia: soro de indivíduos de 30 a 70 anos randomicamente selecionados em um laboratório publico de análises clínicas na área metropolitana do Brasil foram testados para AgHBs/ Anti-HBc Total /Anti-HBs/Anti-HBc-IgM. Todos responderam questionário sociodemográfico contendo perguntas sobre fatores de risco para hepatite B. Resultados: dos 650 participantes, 349 eram BB (51-70 anos) e 301 eram não-BB (30-50 anos). As prevalências estimadas foram: HBsAg (2,3%), Anti-HBs (27,4%). Entre os Anti-HBc Total (17,1%) apenas 2,7% foram Anti-HBc IgM. Os perfis laboratoriais foram caracterizados como suscetibilidade (68%), resposta vacinal (14,8%) e contato com VHB (17,2%). Na distribuição por idade, os BB foram mais susceptíveis, menos vacinados e apresentaram maior frequência de contato/infecção que os não-BB. Diferenças estatisticamente significantes foram encontradas no status contato/infecção e as seguintes variáveis: sexo masculino, uso de drogas ilícitas, compartilhamento de seringas de vidro/agulhas e transfusão de sangue. Não-BB com status contato/infecção relataram ter mais tatuagem/piercing e BB relataram maior uso de seringas de vidro. Conclusão: a maioria da população estudada era suscetível ao VHB, mas os participantes com mais de 50 anos apresentaram tanto uma maior frequência desse status quanto do status contato/ infecção, sugerindo a necessidade de maior atenção à saúde para indivíduos desta faixa etária.
