Neglected tropical diseases in Brazil

Poverty is intrinsically related to the incidence of Neglected Tropical Diseases (NTDs). The main countries that have the lowest human development indices (HDI) and the highest burdens of NTDs are located in tropical and subtropical regions of the world. Among these countries is Brazil, which is ranked 70th in HDI. Nine out of the ten NTDs established by the World Health Organization (WHO) are present in Brazil. Leishmaniasis, tuberculosis, dengue fever and leprosy are present over almost the entire Brazilian territory. More than 90% of malaria cases occur in the Northern region of the country, and lymphatic filariasis and onchocerciasis occur in outbreaks in a particular region. The North and Northeast regions of Brazil have the lowest HDIs and the highest rates of NTDs. These diseases are considered neglected because there is not important investment in projects for the development of new drugs and vaccines and existing programs to control these diseases are not sufficient. Another problem related to NTDs is co-infection with HIV, which favors the occurrence of severe clinical manifestations and therapeutic failure. In this article, we describe the status of the main NTDs currently occurring in Brazil and relate them to the HDI and poverty.

Modulatory activity of antioxidants against the toxicity of Rifampicin in vivo

The World Health Organization (WHO) has shown concern about the burden of tuberculosis in the developing countries. Even though rifampicin is an effective drug in the management of tuberculosis, it has been documented to have some toxic effects in humans. Therefore, this study intends to investigate the modulatory effect of vitamins C and E on the hepatotoxicity, sperm quality and brain toxicity of Rifampicin. Forty Wistar albino rats were used, 10 animals per group. Group 1 animals received 0.3 mL of distilled water, the Group 2 animals received the therapeutic dose of rifampicin, Group 3 animals received therapeutic doses of rifampicin plus vitamin E, while Group 4 received therapeutic doses of rifampicin and vitamin C. The administration was performed orally during three months; the animals were sacrificed by cervical dislocation at the end of that period. Blood samples were collected and liver function and lipid profile was analyzed using fully automated clinical chemistry device. The liver, brain and reproductive organs underwent histopathological examination. Sperm samples were collected from the epididymis to achieve count and motility and morphological analysis. Results showed rifampicin alone to raise (p < 0.05) liver function enzymes (Aspartate amino transferase [AST], Serum alanine amino transferase [ALT] and Total Bilirubin) when compared with controls. While the vitamin E treated group showed remarkable protection, the vitamin C treated group showed questionable protection against the rifampicin induced liver damage. Sperm count results showed an important (p < 0.05) increase in the sperm quality in vitamin E and C treated groups. However, the vitamin E plus Rifampicin treated group showed increased lipid peroxidation. The histopathological findings revealed structural damages by rifampicin in liver, brain and epididymis while some remarkable architectural integrity was observed in the antioxidant-treated groups. It can be concluded that vitamin E or C improved sperm quality and protected against the brain damage caused by rifampicin. Moreover, vitamin E demonstrated remarkable hepatoprotection against rifampicin induced damage while vitamin C shows a questionable hepatoprotection.

Avaliação dos serviços de saúde mental em Moçambique

RESUMO: O instrumento de avaliação de sistemas de saúde mental da organização mundial de saúde (WHO-AIMS)foi usado para a recolha de informações sobre o Programa Nacional de Saúde Mental de Moçambique. O presente estudo tem como objectivo melhorar o Programa Nacional de Saúde Mental e fornecer um ponto de partida para a monitorização das mudanças. Os resultados do estudo permitirão a Moçambique fortalecer a sua capacidade para desenvolver planos de saúde mental baseados em informações com pontos de partida e metas bem definidos. O relatório será também útil para a monitorização do progresso da implementação de reformas nas políticas de saúde mental, na disponibilização de serviços de base comunitária, e no envolvimento dos utentes, seus familiares e outros actores na promoção, prevenção,cuidados e reabilitação em saúde mental. Tendo em conta os antecedentes históricos da saúde mental em Moçambique, a realidade actual clama por reformas profundas voltadas para uma intervenção mais humanizada e com enfoque nos cuidados primários. É nesse contexto que o estudo realizado apresenta resultados relacionados com as políticas, legislação, estratégias e planos de acção e financiamento para a saúde mental; serviços de saúde mental;cuidados primários; recursos humanos e ligação com outros sectores chave. A saúde mental foi avaliada desde o sistema de gestão até ao nível comunitário. Relativamente aos órgãos de gestão, a principal constatação é que existem instrumentos legais para sustentar as iniciativas desta área e influenciar os meios políticos em prol da saúde mental. Todavia, o caminho a percorrer ainda é longo uma vez que não está ainda aprovada nenhuma lei de saúde mental e os financiamentos para a área não permitem a implementação das reformas necessárias. Os serviços ao nível clínico debatem-se com a problemática dos recursos humanos (constituídos principalmente por técnicos de psiquiatria) e disponibilidade de psicofármacos. O modelo biopsicossocial ainda não é implementado integralmente uma vez que são poucos os serviços que oferecem apoio psicossocial (que inclui a reabilitação e reintegração) para além da intervenção farmacológica. Esta pode ser considerada uma das principais causas de recaídas identificadas em todas as províncias. Há uma necessidade urgente de se realizarem pesquisas e levantamentos epidemiológicos que possam servir de suporte para a advocacia em saúde mental com vista a melhoria dos cuidados a prestar aos pacientes e comunidade. Os instrumentos de recolha de informação de rotina não são adequados limitando a fidelidade dos dados recolhidos e a possibilidade de uma gestão dos serviços de saúde mental que responda as reais necessidades da população. Em suma, os resultados aqui apresentados mostram que Moçambique tem uma base que pode ser considerada uma mais valia para a reforma do sistema de saúde mental. Existem, ainda que escassos, recursos como humanos, infra-estruturas e legislação para a prestação dos serviços clínicos. É preciso investir na saúde mental para que os recursos existentes sejam melhorados e expandidos, apostando na criação de equipas multidisciplinares e qualificação das equipas de gestão e equipas clínicas. --------ABSTRACT: The World Health Organization Assessment Instrument for Mental Health Services (WHO-AIMS) was used to collect information about the National Mental Health Program of Mozambique. The present study aims to improve the National Mental Health Program and provide a starting point for monitoring change. The study results will allow Mozambique to strengthen its capacity to develop mental health plans based on information with starting points and well-defined goals. The report will also be useful for monitoring the progress of implementation of reforms in mental health policies, the provision of community-based services, and involvement of users, their families and other stakeholders in the promotion, prevention, care and rehabilitation in mental health. Given the historical background of mental health in Mozambique, the current situation calls for reforms aimed at a more humane intervention focused on primary care. In this context, the study presents results related to policies, legislation, strategies and action plans and funding for mental health; mental health services; primary care; human resources and liaison with other key sectors. Mental health was assessed from the management system to the community level. With regard to the management, the main observation is that there are legal instruments to support the initiatives in this area and to influence the political means on behalf of mental health. However, the pathway is still long as it is not yet approved any Mental Health Law and the funding for the area do not allow the implementation of necessary reforms. Services at the clinical level are struggling with the issue of human resources (consisting primarily of psychiatrist technicians) and availability of psychotropic drugs. The biopsychosocial model is not yet fully implemented since there are few services providing psychosocial support (including rehabilitation and reintegration) in addition to pharmacological intervention. This can be considered a major cause of relapse identified in all provinces. There is an urgent need to conduct research and epidemiological surveys which could provide support for advocacy in mental health in order to improve the mental health car for the patients and community. The routine data collection instruments are not appropriate limiting the fidelity of the data collected and the possibility of a management of mental health services that meets the real needs of the population. In summary, the results presented here show that Mozambique has a groundwork that can be considered an asset for the reform of mental health system. There are, though scarce, human resources, infrastructure and legislation for the provision of clinical services. It’s necessary to invest in mental health so that existing resources are improved and expanded, and to invest on the creation of multidisciplinary teams and qualification of management teams and clinical teams.

Influence of cardiorespiratory fitness and parental lifestyle on adolescents' abdominal obesity

The aims of this study were (1) to analyse the influence of cardiorespiratory fitness (CRF) and parental overweight status (POS) and socioeconomic status (SES) on abdominal obesity. This study was comprised of 779 adolescents (12-18 years). Waist-height ratio (WHtR), 20 m shuttle-run test to ascertain CRF, POS according to World Health Organization recommendations and SES of parents using level of education were analysed. Using WHtR, the prevalence of abdominal obesity was 21.3% (23.5% girls and 17.9% boys; p = 0.062). Regardless of gender, participants who belonged to the WHtR risk group had significantly (p ≤ 0.05) lower CRF scores than the WHtR non-risk group; 84.4% of girls who belonged to the WHtR risk group had one or two overweight parents (p ≤ 0.05). Boys with low CRF (OR: 6.43; CI: 3.33-12.39) were more likely to belong to the WHtR risk group compared with their lean peers. Girls with low CRF (OR: 1.78; CI: 1.14-2.78) and with at least one overweight parent (OR: 2.50; CI: 1.07-5.85) or two overweight parents (OR: 4.90; CI: 2.08-11.54) were associated with the risk of abdominal obesity. This study highlights the influence of adolescents' family on abdominal obesity, especially in girls. Further, the data suggested that low CRF was a strong predictor of risk values of abdominal obesity in adolescence.

The relationship of cardiorespiratory fitness, birth weight and parental BMI on adolescents’ obesity status

The aims of this study were as follows: (1) to analyze differences in cardiorespiratory fitness (CRF), parents' body mass index (BMI) and birth weight (BW) between non-overweight (NOW) and overweight/obese (OV/OB) adolescents, and (2) to investigate the association of those variables with the risk of their biological offspring being OV/OB. This study comprised 788 adolescents (477 girls and 311 boys), aged between 12 and 18 years. CRF was predicted by maximal multistage 20-m shuttle-run test according to the procedures described in FITNESSGRAM. Children's BMI was classified according to the International Obesity Task Force. Adolescents' BW was assessed from each child's pediatric record at birth. Parents' OV/OB status was defined and classified according to the World Health Organization. Socioeconomic status was defined by parental education. The prevalence OV/OB was 21.4 and 5.3%, respectively, and there were no gender differences. The OV/OB adolescents (girls and boys) had significantly (P

Mutilação Genital Feminina - a Importância de Reconhecer e de Saber como Agir

Female genital mutilation, also named female genital cutting or female circumcision, refers to all practices involving total or partial removal of female external genitalia, or causing other lesions without an established health benefit. The World Health Organization estimates that 130 million women have been submitted to genital mutilation and 3 million are annually exposed to such risk in Africa. It has classified the practice of female genital mutation in four types. Portugal is considered a risk country for the practice of genital mutilation because of the high migration rates from the African continent, and women from Guinea-Bissau are at particular risk. A multidisciplinary commission published an Action Program in 2009, with measures directed at providing healthcare professionals with information on how to deal with this problem.

Condições de trabalho, comprometimento organizacional e saúde mental: um estudo no setor da bricolage

A presente investigação tem como objetivo principal avaliar a relação entre as Condições de Trabalho, o Comprometimento Organizacional, a Satisfação Social, e a Saúde Mental dos trabalhadores no setor da Bricolage. É sua intenção compreender se as Condições de Trabalho são preditoras de Comprometimento Organizacional e Satisfação com as Relações Sociais, e se o Comprometimento Organizacional explica o Burnout, a Ansiedade e a Depressão destes trabalhadores. Investiga igualmente, através de análises exploratórias, a possível influência de algumas variáveis sociodemográficas e profissionais nos diversos construtos verificados. Participaram neste estudo, num universo de 564 colaboradores de organizações de venda de material de Bricolage da região Norte de Portugal, 190 trabalhadores (33,7%), sendo que 42,6% (n = 81) são do sexo Feminino e 57,4% (n = 109) do sexo Masculino. A metodologia do estudo seguiu uma abordagem quantitativa, com carácter descritivo, exploratório e preditivo, com utilização de inquérito por questionário. A recolha de dados foi feita num único momento através de uma série de instrumentos, entre os quais: Cuestionario de Condiciones de Trabajo (qCT) – Escalas Método e Ambiente; Three-Component Model of Organizational Commitment; The General Health Questionnaire (GHQ-12); World Health Organization Quality of Life – Bref (WHOQOL-Bref) – Escala das Relações Sociais; Maslach Burnout Inventory – General Survey (MBI-GS); Ficha Demográfico Profissional. As análises psicométricas destes mostraram uma validade e uma fidelidade bastante satisfatória. Os resultados obtidos neste estudo apontam, que as Condições de Trabalho são preditoras, quer do Comprometimento Organizacional, quer da Satisfação com as Relações Sociais. O Comprometimento Organizacional é, preditor significativo de maior Saúde Mental, e igualmente de menor síndrome de Burnout. As análises exploratórias mostraram diferenças significativas em termos de variáveis sociodemográficas (e.g. Idade: Comprometimento Organizacional, Saúde Mental e Burnout; Estado Civil: Condições de Trabalho; Número de Filhos: Comprometimento Organizacional). Quanto às variáveis profissionais, foram encontradas significâncias na Antiguidade (Comprometimento Organizacional e Saúde Mental) e na Função (Comprometimento Organizacional, Condições de Trabalho e Burnout). No final deste trabalho são discutidos e apresentados os principais resultados obtidos e as suas conclusões.

Mutilação Genital Feminina: o que Sabem os Profissionais de Saúde?

Portugal is considered by the World Health Organization (WHO) a risk country for the practice of Female Genital Mutilation (FGM). Objectives: To evaluate the knowledge that health professionals from Maternity Dr. Alfredo da Costa (MAC) have regarding FGM. Population and Methods: Analysis of surveys delivered to health professionals from MAC (a hospital dedicated to reproductive health), between April and June 2008, addressing issues related to the knowledge about FGM. Results: Authors collected 112 valid surveys involving 38 doctors, 48 nurses and 26 medical auxiliaries/administrative personnel. From the respondents, 106 (95%) had heard about FMG practice before, the media being the most reported source of information; 59 (53%) replied they could be able to recognize FGM cases in their clinical practice; however, only 31 (28%) claimed to know the FGM type classiication and 32 (29%) admitted to be prepared to recognize and manage these situations in their own clinical practice; 9 had been consulted explicitly by a FGM practice complication and 1 doctor had admitted having been asked to perform/execute FGM; 13 (12%) recognized that the Portuguese legislation its this practice. Regarding the practice of FGM, 100 (89%) of respondentes stated that it should not be maintained and 97 (87%) stated that it should not be tolerated. However, 42 (38%) considered that if these practices were a reality, then they should be medical assisted. Discussion: Health professionals can play an important role in eliminating the practice of FGM, not only by the proper clinical management of this situation, but also by preventing those communities at risk to resort to FGM. Most health professionals are not prepared to deal with FGM in their clinical practice. It is important to promote a better knowledge on the subject and to create protocols for proper clinical management.

INSECTICIDE-TREATED BED NETS IN RONDÔNIA, BRAZIL: EVALUATION OF THEIR IMPACT ON MALARIA CONTROL

Mosquito nets treated with long-lasting insecticide (LLINs), when used in compliance with guidelines of the World Health Organization, may be effective for malaria vector control. In 2012, approximately 150,000 LLINs were installed in nine municipalities in the state of Rondônia. However, no studies have assessed their impact on the reduction of malaria incidence. This study analyzed secondary data of malaria incidence, in order to assess the impact of LLINs on the annual parasite incidence (API). The results showed no statistically significant differences in API one year after LLIN installation when compared to municipalities without LLINs. The adoption of measures for malaria vector control should be associated with epidemiological studies and evaluations of their use and efficiency, with the aim of offering convincing advantages that justify their implementation and limit malaria infection in the Amazon Region.

PREVALENCE OF CHAGAS DISEASE AMONG BLOOD DONOR CANDIDATES IN TRIANGULO MINEIRO, MINAS GERAIS STATE, BRAZIL

Despite public health campaigns and epidemiological surveillance activities, Chagas disease remains a major health problem in Latin America. According to data from the World Health Organization, there are approximately 7-8 million people infected with Trypanosoma cruzi worldwide, a large percentage of which in Latin America. This study aims to examine the serological profile of blood donors in blood banks of Hemominas hematology center, in the town of Ituiutaba, Minas Gerais State, Brazil. The study sample consisted of 53,941 blood donors, which were grouped according to gender and age. Sample collections were performed from January 1991 to December 2011, and 277 donors (0.5%) were considered serologically ineligible due to Chagas disease. Analysis of data showed no significant difference between genders. As for age, the highest proportion of ineligible donors was from 40 to 49 years (30%), and there was a positive correlation between increasing age and the percentage of patients seropositive for Chagas disease. Therefore, adopting strategies that allow the safe identification of donors with positive serology for Chagas disease is essential to reduce or eliminate indeterminate serological results.

MOLLUSCICIDAL AND LARVICIDAL ACTIVITIES OF Atriplex inflata AERIAL PARTS AGAINST THE MOLLUSK Galba truncatula, INTERMEDIATE HOST OF Fasciola hepatica

Fasciolosis is a widespread parasitosis of farm live-stock in many developing countries. For this reason, it is necessary to search for new substances against parasitic diseases caused by flukes. Indeed, a wide variety of terrestrial plants have been subjected to chemical and pharmacological screening in order to discover their potential for human medicinal use. The molluscicidal and larvicidal activities of Atriplex inflata were tested on Galba truncatula and Fasciola hepatica larval stages infecting this snail in Tunisia. Phytochemical tests were conducted on extracts in order to establish a meaningful relationship with molluscicidal and larvicidal activities. The molluscicidal activity was evaluated by subjecting snails to sample aqueous solutions. Accordingly, hexane, ethyl acetate, methanol and methanol-water (8:2, v-v) were used as extraction solvents. As a result, hexane and ethyl acetate extracts showed potent activity, according to the World Health Organization, giving LC50 = 7.59 mg/L and 6.69 mg/L for hexane extracts of leaves and fruits, respectively. Ethyl acetate extracts gave LC50 = 5.90 mg/L and 7.32 mg/L for leaves and fruits, successively. Molluscicidal activities of powders were less potent on snails, but active according to the World Health Organization. Hexane and ethyl acetate extracts from leaves and fruits gave potent larvicidal activities with a delay rate exceeding 45.50% (45.50- 98.92%). Phytochemical tests showed that these activities may be attributed to the presence of triterpenoids and/or sterols.

LATERAL FLOW ASSAY FOR CRYPTOCOCCAL ANTIGEN: AN IMPORTANT ADVANCE TO IMPROVE THE CONTINUUM OF HIV CARE AND REDUCE CRYPTOCOCCAL MENINGITIS-RELATED MORTALITY

SUMMARYAIDS-related cryptococcal meningitis continues to cause a substantial burden of death in low and middle income countries. The diagnostic use for detection of cryptococcal capsular polysaccharide antigen (CrAg) in serum and cerebrospinal fluid by latex agglutination test (CrAg-latex) or enzyme-linked immunoassay (EIA) has been available for over decades. Better diagnostics in asymptomatic and symptomatic phases of cryptococcosis are key components to reduce mortality. Recently, the cryptococcal antigen lateral flow assay (CrAg LFA) was included in the armamentarium for diagnosis. Unlike the other tests, the CrAg LFA is a dipstick immunochromatographic assay, in a format similar to the home pregnancy test, and requires little or no lab infrastructure. This test meets all of the World Health Organization ASSURED criteria (Affordable, Sensitive, Specific, User friendly, Rapid/robust, Equipment-free, and Delivered). CrAg LFA in serum, plasma, whole blood, or cerebrospinal fluid is useful for the diagnosis of disease caused by Cryptococcusspecies. The CrAg LFA has better analytical sensitivity for C. gattii than CrAg-latex or EIA. Prevention of cryptococcal disease is new application of CrAg LFA via screening of blood for subclinical infection in asymptomatic HIV-infected persons with CD4 counts < 100 cells/mL who are not receiving effective antiretroviral therapy. CrAg screening of leftover plasma specimens after CD4 testing can identify persons with asymptomatic infection who urgently require pre-emptive fluconazole, who will otherwise progress to symptomatic infection and/or die.

Clinical and ultrasound findings before and after praziquantel treatment among Venezuelan schistosomiasis patients

Abdominal ultrasound can be a useful tool for diagnosing periportal fibrosis related to Schistosoma mansoni infection, and also for planning and monitoring the evolution of hepatic morbidity following control measures. We evaluated the standardized ultrasound methodology proposed by the World Health Organization for detecting periportal fibrosis and portal hypertension, among patients from an endemic area in Venezuela, and the impact of praziquantel treatment 3-5 years later. After chemotherapy, complete reversal of periportal lesions was observed in 28.2% of the cases and progression of the disease in 5.1%. Improvement in the hepatic disease started with a reduction in the periportal thickening followed by a decrease in the size of the left hepatic lobe, spleen and mesenteric and spleen veins. Ultrasound confirmed the clinical findings after chemotherapy among the patients with reversal of the disease. However, in patients with more advanced disease, these findings were contradictory. There was no correlation between evolution of the disease seen on ultrasound and age, intensity of infection or serological findings.

Avaliação da cultura de segurança do doente em meio hospitalar : investigação ação numa unidade de radioterapia

RESUMO Introdução e objetivos As organizações internacionais responsáveis pela Qualidade na Saúde e Segurança do doente (Organização Mundial da Saúde, União Europeia), recomendam aos Estados membros a avaliação da cultura de segurança, como condição essencial para se introduzir mudanças nos comportamentos dos profissionais e nas organizações prestadoras de cuidados de saúde, e alcançar melhores níveis de segurança e de qualidade nos cuidados de saúde prestados aos doentes. Constitui objetivo geral deste trabalho contribuir para a implementação da cultura de segurança do doente nos profissionais envolvidos na prestação de cuidados de saúde, concorrendo para a avaliação da cultura de segurança do doente e, consequentemente para a garantia da qualidade dos cuidados prestados. Metodologia 1ª fase – pré-estudo: através da revisão de literatura identificamos o instrumento mais adequado para avaliar a cultura de segurança do hospital, traduzimos e validámos o instrumento. 2ª fase – desenvolvemos um estudo exploratório-descritivo, transversal, retrospetivo, em 3 hospitais portugueses e um estudo exploratório-descritivo, longitudinal, prospetivo, de investigação-ação, numa unidade de radioterapia. Resultados O Hospital Survey on Patient Safety Culture é o instrumento que revela as adequadas características para a avaliação da cultura de segurança nos hospitais portugueses. No que diz respeito à avaliação da cultura de segurança em três hospitais portugueses, podemos destacar que o trabalho em equipa, a expectativas do supervisor e a aprendizagem organizacional são as dimensões com melhores resultados apesar da frequência das notificações e das respostas ao erro não punitivas apresentarem os piores resultados. Verificou-se que a URT se encontra em franca evolução, o que se torna visível sobretudo na adesão à notificação que aumentou à medida que o tempo foi passando. O envolvimento de todos no desenho da intervenção e nas atividades a decorrer na unidade, foi preponderante para a melhoria da segurança do doente. Conclusões Temos consciência que existem muitas questões por responder e que na realidade não há receitas nem diretrizes que possam afirmar que existem relações de causalidade, confrontando uma determinada ação com a consequente mudança cultural. No entanto, estamos convictos que o envolvimento de todos os membros da organização/unidade, o compromisso forte da liderança, uma comunicação efetiva e uma notificação não punitiva são ingredientes essenciais para a melhoria contínua da cultura de segurança do doente.

the liver endoplasmic reticulum in malaria liver infection

Malaria, a disease caused by Plasmodium, represents a major health problem with a still disconcertingly high mortality rate (655 000 malaria deaths were estimated by the World Health Organization in 2012), mainly in Africa [1]. After a bite by an infected Anopheles mosquito occurs, Plasmodium sporozoites reach their target organ, the liver, within minutes. After traversing several hepatocytes, the parasite invades a final one and establishes a parasitophorous vacuole, where it replicates exponentially generating thousands of infective merozoites, the red blood cell infectious forms that are released in the blood stream. The liver stage is the first obligatory phase of malaria infection and, although no symptoms are associated with it, it is absolutely crucial to the establishment of a successful infection.(...)
