    Leprosy is a hyperendemic chronic condition in the Rondônia State . Despite the significant impact of oral health on the quality of life and clinical evolution of leprosy patients, systematic evaluation of oral health status has been neglected. To analyze the dental-clinical profile, self-perceived oral health and dental health service access of leprosy cases in the municipality of Cacoal in Rondônia State , North Brazil, from 2001 to 2012. A descriptive, cross-sectional study design was performed based on dental evaluation and standardized structured instruments. We investigated clinically assessed and self-perceived oral health status, as well as dental health service access. A total of 303 leprosy cases were included; 41.6% rated their oral health as good, and 42.6% reported being satisfied with their oral health. Self-reported loss of upper teeth was 45.5%. The clinical evaluation revealed that 54.5% had active caries. Most (97.7%) cases reported having been to the dentist at least once in their life and 23.1% used public health services. The poor standard of oral health in this population may increase the risk for leprosy reactions, consequently reducing quality of life. Low access to public health dental services and poor self-perceived oral health reinforce the need to achieve comprehensive health care in this population

    Mortality related to tuberculosis-HIV/AIDS co-infection in Brazil, 2000-2011: epidemiological patterns and time trends

    Get PDF
    Co-infection of tuberculosis (TB)-HIV/AIDS is a persistent public health problem in Brazil. This study describes epidemiological patterns and time trends of mortality related to TB-HIV/AIDS co-infection. Based on mortality data from 2000-2011 (almost 12.5 million deaths), 19,815 deaths related to co-infection were analyzed. The average age-adjusted mortality rate was 0.97 deaths/100,000 inhabitants. The highest mortality rates were found among males, those in economically productive age groups, black race/color and residents of the South region. There was a significant reduction in the mortality coefficient at the national level (annual average percent change: -1.7%; 95% CI: -2.4; -1.0), with different patterns among regions: increases in the North, Northeast and Central regions, a reduction in the Southeast and a stabilization in the South. The strategic integration of TB-HIV/AIDS control programmes is fundamental to reduce the burden of mortality related to co-infection in Brazil

    AbstractAlthough titanium and its alloys own good mechanical properties and excellent corrosion resistance, these materials present poor tribological properties for specific applications that require wear resistance. In order to produce wear-resistant surfaces, this work is aimed at achieving improvement of wear characteristics in Ti–Si–B alloys by means of high temperature nitrogen plasma immersion ion implantation (PIII). These alloys were produced by powder metallurgy using high energy ball milling and hot pressing. Scanning electron microscopy (SEM) and X-ray diffraction identified the presence of α-titanium, Ti6Si2B, Ti5Si3, TiB and Ti3Si phases. Wear tests were carried out with a ball-on-disk tribometer to evaluate the friction coefficient and wear rate in treated and untreated samples. The worn profiles were measured by visible light microscopy and examined by SEM in order to determine the wear rates and wear mechanisms. Ti–7.5Si–22.5B alloy presented the highest wear resistance amongst the untreated alloys produced in this work. High temperature PIII was effective to reduce the wear rate and friction coefficient of all the Ti–Si–B sintered alloys

    Get PDF
    Goals: To verify whether the use of Vitamin D as parallel therapy to hospital and drug treatment can be effective in the process of infectious reduction in hospitalized children. Data source: This study is a systematic review and meta-analysis of randomized controlled trials, published between 2011 and the first quarter of 2019, in the Cochrane Library, Medline, US National Library of Medicine and the National Institute of Health (PubMed), Literature databases. Latin American and Caribbean Health Sciences (Lilacs), Scopus and Web of Science. The studies were scored by the Down and Black scale associated with the quality assessment method according to the Cochrane criteria (RCT). Summary of the data: Of the 1475 studies, 09 were included. There is a direct relationship between Vitamin D level and mortality rate in hospitalized children with infections. Conclusion: This study highlighted that the vitamin D deficiency in children under serum analysis during hospitalization triggers severe immunological changes

    Comparison of prophylactic and therapeutic use of short-chain fatty acid enemas in diversion colitis: a study in Wistar rats

    Get PDF
    OBJECTIVES: To study the effect of short-chain fatty-acids on atrophy and inflammation of excluded colonic segments before and after the development of diversion colitis. INTRODUCTION: Diversion colitis is a chronic inflammatory process affecting the dysfunctional colon, possibly evolving with mucous and blood discharge. The most favored hypotheses to explain its development is short-chain fatty-acid deficiency in the colon lumen. METHODS: Wistar rats were submitted to colostomy with distal colon exclusion. Two control groups (A1 and B1) received rectally administered physiological saline, whereas two experimental groups (A2 and B2) received rectally administered short-chain fatty-acids. The A groups were prophylactically treated (5th to 40th days postoperatively), whereas the B groups were therapeutically treated (after post-operative day 40). The mucosal thickness of the excluded colon was measured histologically. The inflammatory reaction of the mucosal lamina propria and the lymphoid tissue response were quantified through established scores. RESULTS: There was a significant thickness recovery of the colonic mucosa in group B2 animals (p = 0.0001), which also exhibited a significant reduction in the number of eosinophilic polymorphonuclear cells in the lamina propria (p = 0.0126) and in the intestinal lumen (p = 0.0256). Group A2 showed no mucosal thickness recovery and significant increases in the numbers of lymphocytes (p = 0.0006) and eosinophilic polymorphonuclear cells in the lamina propria of the mucosa (p = 0.0022). CONCLUSION: Therapeutic use of short-chain fatty-acids significantly reduced eosinophilic polymorphonuclear cell numbers in the intestinal wall and in the colonic lumen; it also reversed the atrophy of the colonic mucosa. Prophylactic use did not impede the development of mucosal atrophy

    El área estuarina del río Massangana (Pernambuco, Brasil) está sujeta a diversas intervenciones antropomórficas resultantes de las actividades del Complejo Industrial y Portuario de Suape, que pueden afectar las comunidades bióticas. Con esa perspectiva, este estudio tuvo como finalidad verificar la composición de la macrofauna bentónica de los sustratos sólidos, en su gradiente de distribución vertical, que sirva de referencia para futuros monitoreos biológicos relacionados a los cambios que pueden ocurrir en el complejo portuario. Se colectaron los invertebrados presentes en un área de 519 m² y su distribución en los sustratos biogénicos y abiogénicos es mostrada en el siguiente trabajo. Fueron encontradas 79 especies presentes principalmente en los mangles y distribuidas en tres zonas del intermareal: Chthamaletum, delimitando el supralitoral, "zona balanoide", conteniendo cirripedios y ostras, en la región intermareal media, y el Bostrychietum, en la región inferior. Esta distribución coincidió en forma general, con el patrón brasileño e internacional de distribución vertical de los invertebrados de manglares. La presencia de sustrato rocoso y la alta salinidad posibilitó la aparición de 28 especies, incluyendo el coral Siderastrea stellata en un área estuarina. La ampliación de la distribución en el litoral brasileño del bivalvo Isognomon alatus, del cirripedio Amphibalanus reticulatus y de los briozoos Biflustra savartii, Bowerbankia gracilis y Conopeum reticulum fue justificada por la proximidad con el Puerto de Suape, facilitada por el transporte pasivo en las embarcaciones. La distribución esparcida de los organismos incrustantes en los sustratos y la ausencia de animales característicos de este ecosistema, como los mejillones, muestran señales de que el ambiente ya sufre algún estrés, resultado de las diversas intervenciones antropomórficas que están aconteciendo

    Vitamin D3 Supplementation: An Option Associated with The Treatment of Multiple Sclerosis: : A Systematic Review and Meta-Analysis

    Get PDF
    Multiple sclerosis (MS) is a chronic complex neurodegenerative disease. A systematic review and meta-analysis were conducted on observational studies and analytics on impact of Vitamin D supplementation in patients with Multiple Sclerosis. In our research, a total of 457 articles were selected and identified for analysis. This systematic review article and meta-analysis, which included evidence from randomized controlled trials conducted with patients with multiple sclerosis, revealed that Vitamin D3 supplementation is effective as an option associated with the treatment of this disease, and that it also has a diffuse protective role against various remission outbreaks in the health. Doses (50,000 IU/week) are appropriate to restore neuroimmunological parameters when used within 12 weeks

    OBJECTIVE: To analyze, stratifield by gender, trends of the new case leprosy detection rates in the general population and in children; of grade 2 disability, and of proportion of multibacillary cases, in the state of Bahia, Brazil from 2001 to 2014. METHODS: A time series study based on leprosy data from the National Information System for Notifiable Diseases. The time trend analysis included Poisson regression models by infection points (Joinpoint) stratified by gender. RESULTS: There was a total of 40,054 new leprosy cases with a downward trend of the overall detection rate (Average Annual Percent Change [AAPC = -0.4, 95% CI -2.8-1.9] and a nonsignificant increase in children under 15 years (AAPC = 0.2, 95% CI -3.9-4.5). The proportion of grade 2 disability among new cases increased significantly (AAPC = 4.0, 95% CI 1.3-6.8), as well as the proportion of multibacillary cases (AAPC = 2.2, 95% CI 0.1-4.3). Stratification by gender showed a downward trend of detection rates in females and no significant change in males; in females, there was a more pronounced upward trend of the proportion of multibacillary and grade 2 disability cases. CONCLUSIONS: Leprosy is still highly endemic in the state of Bahia, with active transmission, late diagnosis, and a probable hidden endemic. There are different gender patterns, indicating the importance of early diagnosis and prompt treatment, specifically in males without neglecting the situation among females

    OBJETIVO: Analisar, segundo gênero, as tendências temporais dos coeficientes de detecção de casos novos de hanseníase na população geral e em crianças, do coeficiente de grau 2 de incapacidade física e da proporção de casos multibacilares no estado da Bahia, no período de 2001 a 2014. MÉTODOS: Estudo de série temporal baseado em dados epidemiológicos relativos à hanseníase oriundos do Sistema de Informação de Agravos de Notificação. A análise de tendência temporal incluiu modelos de regressão de Poisson por pontos de inflexão (Joinpoint), considerando-se a dimensão de gênero. RESULTADOS: Dos 40.054 casos notificados no período, verificou-se tendência de redução no coeficiente de detecção geral (Average Annual Percent Change [AAPC] = -0,4; IC95% -2,8–1,9) e aumento em menores de 15 anos sem significância estatística (AAPC = 0,2; IC95% -3,9–4,5). Para o coeficiente de detecção com grau 2 de incapacidade física, a tendência foi de aumento significativo (AAPC = 4,0; IC95% 1,3–6,8), assim como nos casos multibacilares (AAPC = 2,2; IC95% 0,1–4,3). A análise estratificada por gênero indicou tendência de redução dos coeficientes de detecção entre as mulheres e de manutenção entre os homens, sem significância estatística. Em relação ao coeficiente de detecção em menores de 15 anos, a tendência de redução é mais acentuada nas mulheres do que entre os homens. As mulheres apresentaram tendência mais acentuada de aumento na proporção de casos multibacilares e do coeficiente de detecção de grau 2 de incapacidade. CONCLUSÕES: O estado da Bahia mantém alta endemicidade, transmissão ativa, diagnóstico tardio e provável endemia oculta de hanseníase. Há um padrão diferencial segundo gênero, tornando central o diagnóstico e tratamento oportuno com estratégias diferenciadas para os homens, sem desconsiderar a situação entre as mulheres.OBJECTIVE: To analyze, stratifield by gender, trends of the new case leprosy detection rates in the general population and in children; of grade 2 disability, and of proportion of multibacillary cases, in the state of Bahia, Brazil from 2001 to 2014.
