Community prevalence of methicillin and vancomycin resistant Staphylococcus aureus in and around Bangalore, southern India

INTRODUCTION: Staphylococcus aureus is a known colonizer in humans and has been implicated in community acquired soft tissue infections. However emergence of methicillin resistant S. aureus (MRSA) has aroused great concern worldwide. This study aimed to determine the prevalence of MRSA in the community of Bangalore, southern India. METHODS: Swabs were collected from anterior nares, forearm, dorsum and palm of the hands of 1,000 healthy individuals residing in and around Bangalore, belonging to different socioeconomic strata and age groups. RESULTS: Analysis verified that 22.5% and 16.6% of the individuals presented Staphylococcus aureus and MRSA, respectively, at any of the three sites. Vancomycin resistance was observed in 1.4% of the S. aureus isolates, which was confirmed by detection of the vanA gene. It was interesting to note that 58.8% of the children in the age group 1-5 years-old presented MRSA, the highest percentage compared to other age groups of < 1 (44.4%) year-old, 5-20 (21.7%) years-old, > 40 (11%) years-old and 20-40 (9.9%) years-old. Among the population of various socioeconomic strata, maximum MRSA colonization was observed among doctors (22.2%), followed by upper economic class (18.8%), lower economic class (17.7%), apparently healthy hospital in-patients (16.5%), nurses (16%) and middle economic class (12.5%). Most of the MRSA isolates were capsular polysaccharide antigen type 8 (57.1%). CONCLUSIONS: There is a need for continuous surveillance and monitoring of the presence of MRSA in the community and a clearer understanding of the dynamics of the spread of MRSA will assist in controlling its dissemination.

Epidemiological factors related to the transmission risk of Trypanosoma cruzi in a Quilombola community, State of Mato Grosso do Sul, Brazil

INTRODUCTION: This work was an epidemiological investigation of the risk of Trypanosoma cruzi transmission in the rural Quilombola community of Furnas do Dionízio, State of Mato Grosso do Sul, Brazil. METHODS: Of the 71 animals examined, seven were captured (two opossums, Didelphis albiventris; four rats, Rattus rattus; and one nine-banded armadillo, Dasypus novemcinctus) and 64 were domestic (one canine, Canis familiaris; five pigs, Sus scrofa; two bovines, Bos taurus; five caprines, Capra sp.; and 51 ovines, Ovis aries). Parasitological tests were performed to detect parasites in the blood and to identify the morphology of flagellates. These methods included fresh examinations, buffy coat tests and blood cultures. Molecular analysis of DNA for identification of trypanosomatids was performed by polymerase chain reaction (PCR) with primers S35 and S36. RESULTS: The parasitological tests showed flagellates in an opossum and two cattle. The molecular tests showed DNA from T. cruzi in an opossum and a pig. Triatoma sordida was the only triatomine species found in the community, and it colonized households (four specimens) and the surrounding areas (124 specimens). Twenty-three specimens tested positive for flagellates, which were subsequently identified as T. cruzi by PCR. CONCLUSIONS: Data analysis demonstrated that T. cruzi has a peridomestic life cycle that involves both domestic and wild mammals.

Trauma and envenoming caused by stingrays and other fish in a fishing community in Pontal do Paranapanema, state of São Paulo, Brazil: epidemiology, clinical aspects, and therapeutic and preventive measures

INTRODUCTION: Accidents caused by fish are common in inland fishing communities in Brazil, being work-related injuries in the majority of cases. These populations have no information on the mechanisms of trauma or envenoming. METHODS: Through a questionnaire administered to fishermen, we obtained clinical and epidemiological data on accidents in Rosana, Pontal do Paranapanema, State of São Paulo, Brazil. These data were analyzed and converted into an easily understood prevention and treatment program for the colony. RESULTS: Thirty-nine fishermen replied to the survey. All of the patients had been hurt by fish. Of those mentioned, the yellow catfish (Pimelodus maculatus) was the main fish species associated with injuries, but others also caused trauma to the fishermen. Six fishermen had been envenomed by stingrays. Pain and ulcers were the main symptoms and were described as intolerable. Approximately half of those injured were treated using traditional folk remedies. CONCLUSIONS: The fishermen suffered multiple accidents with catfish, which are venomous and cause intense pain, as well as trauma due to other fish, such as surubins, traíras, freshwater croakers, and piranhas. Approximately 16% of those interviewed presented with envenomation from stingrays. Our data and previous experience in the area led to the creation of a pamphlet with clear language that can effectively help fishermen in the region, an area in need of health services and disease prevention. This initiative also applies to the whole La Plata River basin, which has similar fauna.

Antibody levels in children after 10 years of vaccination against hepatitis B: a brazilian community-based study

INTRODUCTION: It is known that the hepatitis B (HB) vaccine is effective, but it is alarming that sudden drops of antibody levels may coincide with the onset of adolescence. METHODS: Antibody levels against HB vaccine surface antigen (anti-HBs) and HB vaccine core antigen (anti-HBc) were measured on the blood samples of children with a mean age of 11.4 years. RESULTS: About 54.8% had protective levels of anti-HBs. Of those who were anti-HBc-positive (4.4%), an average of 218.4 anti-HBs mIU/mL was found. CONCLUSIONS: Immunological protection was found in the majority of children. However, more studies are needed to elucidate the heritability of nonresponders and establish strategies against such events.

Assessing the community needs of mental health residential care service users in Republic of Moldova

RESUMO: Background: Problemas de saúde mental são um grande problema clínico e social na República da Moldávia, representando uma quota significante de deficiência, sendo classificada no top cinco das dez linhas na hierarquia das condições. A taxa de incidência tem sido crescente na República da Moldávia, atingindo cerca de 15.000 por ano (14,655 em 2011), ou seja, 411,4 por 100 mil habitantes, e uma taxa de prevalência de 97.525 pessoas em 2011, ou seja, 2,737.9 por 100 mil habitantes. Sistema de atendimento psiquiátrico fornece serviços de saúde mental escassos a nível da comunidade, visando principalmente terapia hospitalar, centralizada, através de uma rede de três hospitais psiquiátricos, com 1.860 camas e 4 sanatórios psico- neurológicos com 1890 camas, assim alimentando-se a estigmatização do paciente. Objetivos: O objetivo deste estudo foi a avaliação das necessidades individuais dos beneficiários e do seu nível de autonomia dentro de cuidados residenciais, para o planeamento de reformas de saúde mental e desinstitucionalização na República da Moldávia. Este estudo foi encomendado pelo Ministério do Trabalho, Proteção Social e da Família e pelo Ministério da Saúde, com o apoio da Organização Mundial da Saúde, para determinar o cumprimento eficaz do artigo 19 da Convenção da ONU. O estudo tem os seguintes objetivos: Avaliar o nível de autonomia dos residentes nos hospitais psiquiátricos e sanatórios psico-neurológico, usando uma amostra representativa de 10 por ce nto do número total de pacientes/residentes e comparação cruzada; Para avaliar quatro sanatórios psico-neurológicos para adultos e três hospitais psiquiátricos; Para desenvolver recomendações para o planeamento da desinstitucionalização das pessoas com problemas de saúde mental e colocação na comunidade com base nos resultados do estudo. Metodologia e resultados: O estudo fez uso de duas ferramentas globais: questionário para a avaliação individual dos residentes do estabelecimento de saúde mental, e questionário de avaliação institucional. Todos os entrevistados foram divididos em quatro categorias conforme com o grau de dependência e preparação de viver de forma independente na comunidade. Apenas 1,2% dos entrevistados de PNHB eram totalmente dependentes de terceiros ou serviços especializados, tornando-se a categoria 4, que necessitam de cuidados e apoio contínuo. No PH esta categoria de pessoas é ausente. Conclusões: A condição dos entrevistados foi pior em PNBH que em PH. No entanto, ainda, aqueles que estão prontos para ser desinstitucionalizados correspondem com a maior parte dos entrevistados. Todos os hospitais tinham o consentimento do utente para admissão e tratamento, enquanto não houve consentimento qualquer em PNBH. É bastante óbvio que tanto os hospitais como também a sistema de assistência residencial não atingem a sua finalidade, o que significa que a maioria dos utentes pode ser desinstitucionalizados, sem qualquer terapia de suporte.------------------ABSTRACT: Background: Mental health problems are a major clinical and social issue in the Republic of Moldova,accounting for a significant share of disability and ranking in top five of the ten lines in the hierarchy of conditions. The incidence rate has been growing in the Republic of Moldova to reach approximately 15 thousand a year (14,655 in 2011), i.e. 411.4 per 100 thousand population, and a prevalence rate of 97,525 thousand people in 2011, i.e. 2,737.9 per 100 thousand population. Psychiatric care system provides for scanty mental health services at community level, aiming mainly at centralized hospital-based therapy through a network of three psychiatric hospitals tallying up 1,860 beds and 4 psycho-neurological boarding houses with 1,890 beds, thus fuelling up patient stigmatization. Objectives: The purpose of this study was to assess the individual needs of beneficiaries and their level of autonomy within residential care for the planning of mental health system reforms and deinstitutionalization in the Republic of Moldova. This study was commissioned by the Ministry of Labour, Social Protection and Family and by the Ministry of Health, with the World Health Organization support, to provide for effective enforcement of article 19 of the UN CRPD. The study pursued the following goals: To evaluate the level of autonomy of the psychiatric hospital and psycho-neurological boarding house residents by using a representative sample of 10 per cent of the total number of patients / residents and cross-comparison; To evaluate four psycho-neurological boarding houses for adults and three psychiatric hospitals; To develop recommendations for planning the deinstitutionalization of people with mental health problems and community placement based on the study findings.Methodology and results: The study made use of two global tools: questionnaire for individual assessment of mental health facility residents, and institutional assessment questionnaire. All interviewees were divided into four categories by one’s degree of dependence and readiness to live independently in the community. Only 1.2% of respondents from PNHB were fully dependent on a third party or specialized services, making up category 4, requiring continuous care and support. In PH this category of people is absent.Conclusions: The condition of respondents was worse in PNBH than in PH. However, yet, those ready to be deinstitutionalized accounted for most of respondents there. All hospitals had the resident’s consent to admission and treatment, whereas there was no consent in PNBH whatsoever. It is quite obvious that both the hospitals and residential care system do not achieve their intended purpose, meaning that the majority of residents may be deinstitutionalized without any support therapy.

Community-acquired methicillin-resistant Staphylococcus aureus carrying SCCmec type IV in southern Brazil

INTRODUCTION: Methicillin-resistant Staphylococcus aureus (MRSA) is an important pathogen commonly associated with nosocomial infections. However, it has also been associated with community-acquired skin and soft tissue infections (CA-MRSA). There are few data on the identification and prevalence of CA-MRSA infections in Brazil. METHODS: This is a cross-sectional study of 104 patients with community-acquired skin infections attending two health care centers in Porto Alegre, southern Brazil. MRSA isolates were characterized by molecular methods, including detection of the mecA gene by PCR, gene SCCmec typing, Panton-Valentine leukocidin (PVL) detection, pulsed-field gel electrophoresis (PFGE), and multilocus sequence typing (MLST). RESULTS: From the 104 samples, 58 Staphylococcus aureus isolates were obtained, of which five (8.6%) had a CA-MRSA-resistant profile. All five isolates had the mecA gene and amplified to SCCmec type IV. Analysis of chromosomal DNA by PFGE revealed the presence of two clusters related to international clones (OSPC and USA 300), with a Dice similarity coefficient >80%. The study was complemented by MLST, which detected three different strains: ST30, ST8, and ST45, the latter not presenting any relation with the clones compared in PFGE. CONCLUSIONS: The presence of CA-MRSA reveals an important change in the epidemiology of this pathogen and adds new elements to the knowledge of the molecular biology of infections by MRSA with SCCmec type IV in southern Brazil.

Who uses NHS saúde 24 hotline? Has the user changed over time?

There has been an increase in the use of telephone-based services and internet throughout the years and, therefore, the Saúde 24 Hotline has become an important service in Portugal. This service aims to screen, counsel and refer the patient in order to avoid unnecessary visits to health institutions and also to indicate the most appropriate resource according to the illness. This work has two different questions: the first one examines the determinants of satisfaction that have more influence on the overall satisfaction of the Saúde 24 Hotline users. The second one aims to analyze if the confidence level of the users is increasing over time, measured by following the recommendation. The first study was conducted on a random sample collected from June to October 2014, which was taken from the User Satisfaction Survey. The second approach includes data from January 2008 to December 2014 from the Clinical Data Base of all users who have called the Hotline. Findings suggest that the majority of users are very satisfied with the service and the variables with more impact on the overall satisfaction are commitment and availability from the nurse, adequacy of call duration and quick identification of the problem. The survey indicates that 94% of respondents follow the recommendation and on average people have called the hotline 3 times in the previous year. The results from the Clinical Database show that people who were recommended to go to the emergency room are more likely to follow the advice than the people who were recommended to book routine appointments

AbstractINTRODUCTION: This study evaluated the effects of cattle removal on the Culicidae mosquito community structure in a tropical dry forest in Brazil.METHODS: Culicidae were collected during dry and wet seasons in cattle presence and absence between August 2008 and October 2010 and assessed using multivariate statistical models.RESULTS: Cattle removal did not significantly alter Culicidae species richness and abundance. However, alterations were noted in Culicidae community composition.CONCLUSIONS: This is the first study to evaluate the impact of cattle removal on Culicidae community structure in Brazil and demonstrates the importance of assessing ecological parameters such as community species composition.

Hepatitis B and C in a Brazilian deaf community

ABSTRACTINTRODUCTION:Although deaf people are exposed to hepatitis B and C risk factors, epidemiological studies regarding these diseases in deaf people are lacking.METHODS:After watching an explanatory digital versatile disc (DVD) in Brazilian Sign Language, 88 deaf people were interviewed and tested for hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), hepatitis B core antibody (anti-HBc), and hepatitis C virus antibody (anti-HCV).RESULTS:The prevalence of hepatitis B markers was 8%; they were associated with incarceration and being born outside the State of São Paulo. No cases of hepatitis C were identified.CONCLUSIONS:Participants showed a substantial lack of knowledge regarding viral hepatitis, indicating a need for public policies that consider linguistic and cultural profiles.

RESULTS: Participants with higher levels of education were more likely to identify correctly the vector of the disease. CONCLUSIONS: The results emphasize the relevance of health education programs, the continuous promotion of educational campaigns in the media, the role of the television as a source of information, and the importance of motivating the population to control the vector.

Factors associated with non-adherence to the treatment of vivax malaria in a rural community from the Brazilian Amazon Basin

Abstract: INTRODUCTION We investigated the association between demographic and behavioral factors and non-adherence to antimalarial therapy. METHODS A demographic questionnaire and 5-item self-reported questionnaire regarding non-adherence were completed by 135 patients after treatment for Plasmodium vivax. RESULTS Treatment interruption, but not demographic factors, was significantly associated with non-adherence to therapy. The likelihood of non-adherence was 5.16 times higher when the patients felt better than when they felt worse. The relative risk of parasitic resurgence was 3.04 times higher in non-adherent patients. CONCLUSIONS Treatment interruption is significantly associated with treatment adherence.

Cataract surgery: expectations of patients assisted during a community project in São Paulo, state of São Paulo, Brazil

OBJECTIVE: To identify social characteristics and expectations of individuals seen during a community project for the treatment of senile cataracts. Expected results from their eye surgery and its consequences to their quality of life were studied as well. METHODOLOGY: Cataract patients (visual acuity equal to or lower than 0.2 in the more superior eye) aged 50 years or over, were surveyed by means of interviews held during their visit at the Cataract Project in São Paulo city, State of São Paulo, Brazil, in 1999. RESULTS: The sample was composed of 331 subjects of low socioeconomic level ranging in age from 50 to 97 years (average = 71.8 years). Expectation of total recovery from the cataract condition by means of surgery was declared by 80.0% of the respondents, with no significant differences between male and female subjects (P < 0.1723). Hope to resume manual activities was expressed by 59.8%. CONCLUSION: A predominance of expectations of resuming normal activity and achieving a better quality of life after cataract surgery were identified.

Community indentification in peer-t-peer collaborative consumption services

Even though collaborative consumption (CC) is gaining economic importance, research in CC is still in its infancy. Consumers’ reasons for participating have already been investigated but little research on consequences of participation has been conducted. This article examines whether interactions between customers in peer-to-peer CC services influence the willingness to coproduce service outcomes. Drawing on social exchange theory, it is proposed that this effect is mediated by consumers’ identification with the brand community. Furthermore, continuance intention in CC is introduced as a second stage moderator. In a cross-sectional study, customers of peer-to-peer accommodation sharing are surveyed. While customer-to-customer interactions were found to have a positive effect on brand community identification, brand community identification did not positively affect co-production intention. Surprisingly, the effect of brand community identification on co-production intention was negative. Moreover, continuance intention of customers did not moderate this relationship. Bearing in mind current challenges for researchers and companies, theoretical and managerial implications are discussed.
