Morbidity trend and space-time clusters of COVID-19 occurrence in children and adolescents.

OBJECTIVE: To analyze the morbidity trend and space-time distribution clusters of confirmed COVID-19 cases in children and adolescents. METHOD: An ecological study of COVID-19 cases confirmed in the Information System from 2020 to 2022 in the age group from 0 to 19 years old, residents in Mato Grosso municipalities, Brazilian Midwest region. A trend analysis of the monthly morbidity rate of cases/100,000 inhabitants was used, following Prais-Winsten's regression. A space-time distribution of the Bayesian incidence rate per 100,000 inhabitants was performed, in addition to a space-time scan to identify high-risk clusters. RESULTS: Of all 79,592 COVID-19 cases studied, 51.6% were in females and 44.21% in people aged 15-19 years old. The mean monthly rate was 265.87 cases per 100,000 inhabitants, with a stationary trend in the period analyzed (Monthly Percentage Variation [MPV]) = 12.15; CI95%[MPV]: -0.73;26.70). The morbidity rate due to COVID-19 was higher in the female gender (283.14/100,000 inhabitants) and in the age group from 15 to 19 years old (485.90/100,000 inhabitants). An increasing trend was observed with a greater monthly time variation of 14.42% (CI95%[MPV]: 1.28;29.28)] among those aged from 10 to 14 years old. The primary cluster, which was also the one with the highest Relative Risk (RR = 5,16, p-value = 0.001), included 19 municipalities located in the North health macro-region. CONCLUSION: The findings indicated a monthly stationary trend in the study population, an increase in the age group from 10 to 14 years old, and areas at a higher risk for the disease in the North health macro-region of the state.

Organizational factors and safe food handling by food service workers: a scoping review protocol.

OBJECTIVE: The objective of this scoping review is to explore and map the scientific evidence on organizational factors related to safe food handling by food service workers to prevent foodborne disease. INTRODUCTION: According to the World Health Organization, more than 600 million people become ill each year due to foodborne diseases. Improper food handling is one of the main causes of such diseases. Despite the growing literature on safe food handling, many studies focus on assessing and discussing cognitive variables, such as food safety knowledge. This indicates a need to study this topic from a new perspective, for example, through its organizational factors. INCLUSION CRITERIA: The review will include quantitative and qualitative studies on food handlers (ie, individuals who have direct or indirect contact with food during their professional duties) working in food services (ie, institutional or commercial establishments). Food handlers involved in industrial processing, planting, harvesting, or working on the street (street food) or in the home will be excluded. Eligible studies will explore the organizational factors of safe food handling that influence employee behavior regarding food production. METHODS: This review will use the JBI methodology for scoping reviews to identify published and unpublished studies in all languages, with no date limit. The following databases will be searched: Scopus, CINAHL, Embase, Web of Science, MEDLINE, PsycINFO, and Food Science and Technology Abstracts. A structured search for gray literature will also be conducted. Titles, abstracts, and full texts of articles will be screened by 2 independent reviewers for inclusion, with discrepancies resolved by a third reviewer. Data will be extracted using a standardized form. The results will be summarized in tabular or graphical format, accompanied by a narrative summary. KEY DETAILS OF THIS REVIEW PROJECT ARE AVAILABLE IN OPEN SCIENCE FRAMEWORK: https://osf.io/hxfe4.

Primary health care essential and derivative attributes in children and adolescents with leprosy / Atributos esenciales y derivados de la atención primaria de la salud en niños y adolescentes con lepra / Atributos essenciais e derivados da atenção primária à saúde em crianças e adolescentes com hanseníase

ABSTRACT Objective: to assess the presence and extension of Primary Health Care essential and derivative attributes in the assistance provided to children and adolescents with leprosy. Method: a cross-sectional study of an evaluative nature, with a quantitative approach. The information was obtained through interviews with nurses and physicians (n=37) working at Primary Health Care units in the care of children and adolescents with leprosy in the municipality of Parauapebas, Pará, Brazil, between October 2021 and February 2022. Mean, minimum, maximum and standard deviation values were used in the descriptive analyses, as well as the Levene test, Student's t-test. Pearson's Correlation Coefficient and a 5% confidence level. Results: 45.9% of the study participants had attended up to two training programs in leprosy care and 32.4% were trained in minors with the disease. When analyzing the mean values of each attribute, low orientation of the service provided and lower values of the general mean were observed in the analysis of attributes related to Access and Continued Care (score 3.4, SD±1.3; and score 3.8, SD±1.7 respectively). There was a regular positive correlation in most of the evaluated attributes and a significant strong positive correlation between care coordination and Professional/Community Orientation: r=0.601 and r=0.651, respectively. Conclusion: there is evidence of weaknesses in health care for children and adolescents with leprosy related to low service orientation; however, qualification in Care coordination exerts a positive influence on Professional orientation and Community orientation with an impact on service surveillance.

Social school contacts of multibacillary leprosy cases in children living in the hyperendemic region of the Midwest of Brazil

Abstract Objective: To analyze the prevalence of Mycobacterium leprae detection and the associated factors among social contacts in the school environment of multibacillary cases living in a hyperendemic municipality of the state of Mato Grosso. Methods: Cross-sectional study with 236 social contacts of multibacillary leprosy from public schools and residents in Cuiabá (Mato Grosso) in 2018. The sources of information were interviews and nasal swab tests for molecular analysis by polymerase chain reaction - PCR. For the prevalence ratio estimates, crude and adjusted analyses were performed using robust Poisson regression and their respective confidence intervals (95% CI). The ArcGIS 9.1 software was used for the geographic distribution analyses. Results: The prevalence of detection of M. leprae in social contacts was 14%. A total of 63.6% of the schools surveyed had 5.1% to 50% of the social contacts of leprosy with positive PCR. The analysis of the geographic distribution in the neighborhoods showed a high prevalence of infection, being higher than 50% in some localities. The highest proportion of positive results occurred in the northern region of the city and from a precarious socioeconomic class. Conclusion: The results showed a high prevalence of detection of M. leprae among social contacts in areas with poor socioeconomic conditions. In these regions, there is a greater risk of

Resistência das populações de Aedes (Stegomyia) aegypti (Linnaeus, 1762) (Insecta, Diptera, Culicidae) aos inseticidas utilizados para o controle: estado da arte do conhecimento / Resistance of Aedes (Stegomyia) aegypti (Linnaeus, 1762) (Insecta, Diptera, Culicidae) populations to insecticides used for control: art state of knowledge

Introdução: cerca de quatro bilhões de pessoas residem em áreas com risco de dengue, uma arbovirose transmitida pelo mosquito Aedes (Stegomyia) aegypti (Linnaeus, 1762) (Insecta, Diptera, Culicidae). Na tentativa de combater esse vetor e reduzir a disseminação da dengue, o meio de controle vetorial frequentemente utilizado são os inseticidas. Entretanto, o uso indiscriminado destes no controle do mosquito está relacionado aos mecanismos de resistência desse vetor. Objetivo: mapear as evidências científicas relacionadas à resistência do mosquito A. aegypti aos inseticidas utilizados para o controle populacional. Metodologia: revisão de escopo, segundo metodologia Instituto Joana Briggs, em bases de dados indexadas: PubMed, Embase, CINAHL, Web of Science, SCOPUS e Biblioteca Virtual em Saúde. Através do mnemônico PCC (população, conceito e contexto), elaborou-se a estratégia de busca utilizando descritores do Decs e Mesh. Resultados: foram encontrados 1.631 estudos sobre a temática. Após critérios de elegibilidade e seleção, foram incluídos 30 estudos específicos sobre resistência do Aedes aegypti a inseticidas foram incluídos na revisão. A maior parte tratou de forma experimental e 28 (93,3%) estudos trabalharam o controle químico. Em relação à resistência a inseticidas, em 20 estudos (66,6%) constatou-se resistência metabólica e em 9 (30%) a resistência mediada pela alteração da variabilidade genética. Os estudos que observaram mutação não deixam claro se a mutação gênica é especificamente devido à ação mutagênica aos inseticidas. Conclusões:o A. aegypti desenvolve adaptações que lhe conferem resistência aos inseticidas, sendo que esses mecanismos de resistência estão relacionados à variabilidade genética e a adaptações metabólicas, que são transmitidas a seus descendentes ao longo das gerações. Assim, torna-se necessário um avanço nos estudos visando não apenas identificar e explicar os mecanismos de resistência, mas encontrar meios alternativos de manejo que possam controlar o inseto sem ocasionar resistência aos mesmos.

Introduction: about four billion people live in areas at risk of dengue, an arbovirus transmitted by the Aedes (Stegomyia) aegypti (Linnaeus, 1762) (Insecta, Diptera, Culicidae). To combat this vector and reduce the spread of dengue, the means of vector control often used are insecticides. However, their indiscriminate use in mosquito control is related to the resistance mechanisms of this vector. Objective: to map the scientific evidence related to the resistance of the Aedes aegypti mosquito to the insecticides used to control dengue. Methodology: scope review, according to the Joana Briggs Institute methodology, in indexed databases: PubMed, Embase, CINAHL, Web of Science, SCOPUS and Virtual Health Library. Using the mnemonic PCC (population, concept and context), a search strategy was developed using Decs and Mesh descriptors. Results: 1,631 studies on the subject were found. After eligibility and selection criteria, 30 specific studies on Aedes aegypti resistance to insecticide were included in the review . Most treated experimentally and 28 (93.3%) studies worked on chemical control. Regarding the resistance to insecticide, in 20 studies (66.6%) there was found metabolic resistance and in 9 (30%) resistance mediated by modification on the genetic variability. Studies that have looked at mutation do not make it clear whether the gene mutation is specifically due to mutagenic action of insecticides. Conclusions: Aedes aegypti develops adaptations that gives them resistance to insecticides, and these resistance mechanisms are related to genetic variability and to metabolic adaptations, which are transmitted to its descendants over generations. Thus, it is necessary to perform advance in studies aiming not only to identify and explain the resistance mechanisms, but to find alternative means of management that can control the insect without causing resistance to them.

Leprosy patients quality of life: a scoping review.

OBJECTIVE: To explore the scientific evidence regarding the leprosy patients quality of life. METHOD: Scoping review according to the Joanna Briggs Institute methodology, with articles indexed in PubMed, Cochrane, LILACS, Embase, CINAHL, Scopus, Web of Science, PsyINFO, INFOLEP, and Google Scholar databases, published in full in Portuguese, English, or Spanish. RESULTS: Seventy-four studies were identified, with 71 of quantitative approach and 3 with a mixed method. There was a predominance of studies published in Brazil (58.1%), with an adult population, (97.3%) and recruited in reference centers for the treatment of leprosy (52.7%). There was greater use of the WHOQOL-bref (50%) and SF-36 (18.9%) instruments to assess quality of life. The study showed that the greatest impairment in quality of life was related to the delay in the diagnosis of the disease, to leprosy reactions, physical disabilities, neuropathic pain, and stigma. CONCLUSION: Most studies were developed in endemic countries, with adults, and based on observational studies, and the worst scores obtained were associated with physical domain impairment.

Atmospheric Pollution Exposure Increases Disease Activity of Systemic Lupus Erythematosus.

Previous studies have shown that high levels of air pollutants may increase activity of systemic lupus erythematosus (SLE). The aim of this study is to analyze the association between pollutants originating from the Brazilian Legal Amazon and SLE activity. This is a retrospective longitudinal cohort study with patients with SLE in the General Hospital in Cuiabá, Brazil. The association with SLE activity was measured using the SLE disease activity index (SLEDAI) and data on air quality-PM2.5 and CO, published on the websites of the State Department of Environment and the Center for Weather Forecasting and Climate Studies. To assess the effect of daily concentrations of pollutants on SLEDAI scores, the generalized estimation equation (GEE) model was used. A total of 32 female patients were assessed, in 96 doctor's appointments. The average SLEDAI score was 6 points (±5.05). GEE showed an association of disease activity with both higher rates of wildfires (p = 0.021) and average CO rate (p = 0.013), but there was no statistical association between particulate levels and SLE activity. The results suggest that variations in air pollution are associated with the activity of autoimmune rheumatic diseases.

Prevalence of Blastocystis sp. infection in several hosts in Brazil: a systematic review and meta-analysis.

BACKGROUND: Blastocystis sp. affects a wide variety of animals and is the most common protozoan in human fecal samples with potential pandemic distribution. In the present study, a systematic review and meta-analysis were conducted to determine the prevalence and distribution of Blastocystis sp. in different classes of hosts in Brazil. METHODS: Studies that analyzed hosts of various classes, including humans, domestic animals, wild animals or captive animals, were considered. The pooled prevalence of Blastocystis sp. infection was estimated by random effects models. RESULTS: For humans, similar prevalence rates were found for males (31.0%, 95% CI: 17.0-45.0%; weight 10%) and females (28.0%, 95% CI: 16.0-41.0%; weight 10%); the state of Mato Grosso do Sul showed the highest prevalence, with 41.0% positivity (95% CI: 36.0-46.0%; weight 2.9%). The prevalence among immunocompromised patients was 5.0% (95% CI: 3.0-7.0%; weight 10%), and the most common cause of immunosuppression was hemodialysis, with 23.0% (95% CI: 17.0-29.0%; weight 12.4%). Among classifications according to interaction with humans, wild and domestic animals presented values of 19.0% (95% CI: 7.0-31.0%; weight 42.6%) and 17.0% (95% CI: 13.0-21.0%; weight 29.6%), respectively. Among these animals, mammals (39.0%, 95% CI: 21.0-56.0%; weight 47.3%) and birds (18.0%, 95% CI: 10.0-27.0%; weight 39.3%) exhibited the highest prevalence. Phylogenetic analysis of Blastocystis sp. revealed greater genetic diversity for clades of subtypes (STs) ST1, ST2 and ST3. CONCLUSIONS: The overall prevalence of Blastocystis sp. in the Brazilian human population was 24%, which reflects the reality in the South, Southeast and Midwest regions, where prevalence rates of up to 40% were found. Among animals, mammals and birds exhibited the highest prevalence.

Leprosy: prevalence and factors associated with seropositivity for anti-NDO-LID antibodies in children under 15 years of age.

BACKGROUND: A high prevalence of leprosy among children under 15 years of age indicates the need to implement actions to prevent new cases of the disease. Serological tests have been developed with the aim of helping to control the disease by indicating, through seropositivity, the presence of infection. OBJECTIVE: To analyze the prevalence and factors associated with seropositivity rate for anti-NDO-LID antibodies in children under 15 years of age, contacts of leprosy patients. METHOD: We performed a cross-sectional study with 210 children under 15 years old of age. Of them, 50 were household contacts and 160 were neighborhood contacts living in the municipality of Cuiabá, state of Mato Grosso, in 2016. The data were obtained from interviews and the NDO-LID rapid test during home visits from February to July 2016. For the analysis, we used Poisson regression and prevalence ratio. RESULTS: Seropositivity in contacts was 6.2%. Variables associated with seropositive tests included sex (PR = 1.05; 95% CI: 1.01 - 1.08), race/skin color (PR = 0.95; 95% CI: 0.90 - 0.99), residence area (PR = 1.05; 95% CI: 1.01 - 1.09), and number of people per household (PR = 1.06; 95% CI: 1.02 - 1.08). STUDY LIMITATIONS: The small sample size, besides leading to wide confidence intervals, may have been a limitation for the identification of associated factors. CONCLUSIONS: The prevalence of seropositivity was high. Variables associated with NDO-LID seropositivity included female sex, not to be brown skinned, live in urban areas, and live with five or more people.

Diagnostic accuracy of Enzyme-Linked Immunosorbent Assays to detect anti-Leishmania antibodies in patients with American Tegumentary Leishmaniasis: a systematic review.

American Tegumentary leishmaniasis (ATL) is an infectious disease caused by several species of Leishmania . Even though the direct detection of parasites has low sensitivity, it is still the gold standard for the laboratory diagnosis of ATL. Recent studies have shown promising results of Enzyme-Linked Immunosorbent Assays ( ELISAs) using recombinant antigens. The aim of this study is to compare the accuracy of ELISAs using novel antigens with the standard ELISA based on soluble antigens of Leishmania (SLA) to diagnose ATL. Studies that analyzed patients with ATL and studies that evaluated the diagnostic accuracy of ELISAs using novel antigens and SLA were included. The Fourteen studies from PubMed, Regional Portal of the Virtual Health Library (BVS), Brazilian Society of Dermatology, Virtual Health Library (IBECS), Literature in the Health Sciences in Latin America and the Caribbean (LILACS), Medical Literature Analysis and Retrieval System Online (Medline), Elsevier Embase, Cochrane Library, The National Institute for Health and Care Excellence (NICE), and Cumulative Index to Nursing and Allied Health Literature (CINAHL) were included. The novel ELISA antigens showed a high sensitivity (93.8%-100%) and specificity (82.5-100%), a better diagnostic performance than SLA-based ELISAs (1-97.4% and 57.5-100%, respectively). Only 10 studies analyzed cross-reactions in serum samples from patients with Chagas disease, and only two studies reported a percentage of cross-reactivity. In this systematic review, the novel ELISA antigens showed better sensitivity and specificity with respect to SLA-based ELISAs. However, a meta-analysis should be performed to confirm this finding.

Leprosy in individuals under the age of fifteen in priority cities, Mato Grosso, Brazil. / Hanseníase em menores de quinze anos em municípios prioritários, Mato Grosso, Brasil.

OBJECTIVES: We aimed to compare the sociodemographic, clinical and epidemiological characteristics of individuals under the age of 15, reported to have leprosy, and who lived in priority and non-priority cities, as well as to compare the spatial distribution of these reported cases in such cities. This is a cross-sectional study of new leprosy cases in individuals under the age of 15 (n=429) registered in the Information System for Notifiable Diseases from the State of Mato Grosso, Brazil, between 2011 and 2013. The diagnosed cases were compared regarding sociodemographic, clinical and epidemiological aspects using the chi-square test at a 5% significance level. The spatial distribution was made through ArcGIS 10.2 software. RESULTS: Of the 141 assessed cities in the state, according to the spatial distribution, 58.1% (n=82) showed a high, very high and hyper-endemic mean incidence coefficient, and, of these, 34.1% (n=28) include the group of priority municipalities. Of the new cases included in the study, 73.9% (n=317) were reported in priority cities. We observed a difference in the proportion of cases registered among the cities, with a greater proportion in priority cities, in the age group from five to nine years old (χ²=4.09; p=0.043), in the white race (χ²=7.01; p=0.008) and in the tuberculoid clinical form (χ²=3.89; p=0.048). There was a greater proportion in non-priority cases with regard to non-urban areas (χ²=24.23; p<0.001), two to five skin lesions (χ²=5.93; p=0.014) and spontaneous demand (χ²=6.16; p=0.013). CONCLUSION: The differences highlighted regarding clinical and epidemiological characteristics between the cities demonstrate the difficulty of endemic control in both municipality groups.

OBJETIVOS: Comparar as características sociodemográficas, clínicas e epidemiológicas de indivíduos menores de 15 anos notificados com hanseníase entre os municípios prioritários e os não prioritários, bem como a distribuição espacial destes casos registrados em tais municípios. Trata-se de um estudo transversal a partir de casos novos de hanseníase em menores de 15 anos (n=429) registrados no Sistema de Informação de Agravos de Notificação do estado de Mato Grosso, entre 2011 e 2013. Os casos diagnosticados foram comparados quanto aos aspectos sociodemográficos, clínicos e epidemiológico por meio do teste do qui-quadrado ao nível de significância de 5%. A distribuição espacial foi feita por meio do software ArcGis 10.2. RESULTADOS: Dos 141 municípios do estado avaliados segundo a distribuição espacial, 58,1% (n=82) apresentaram coeficiente médio de incidência alto, muito alto e hiperendêmico, sendo que, destes, 34,1% (n=28) contemplam o grupo dos prioritários. Dos casos novos incluídos no estudo, 73,9% (n=317) foram notificados em municípios prioritários. Observou-se diferença na proporção de casos registrados entre os municípios, com maior proporção nos prioritários quanto à idade de 5 a 9 anos (χ²=4,09; p=0,043), raça branca (χ²=7,01; p=0,008) e forma clínica tuberculoide (χ²=3,89; p=0,048), e maior proporção nos não prioritários quanto à zona não urbana (χ²=24,23; p<0,001), duas a cinco lesões (χ²=5,93; p=0,014) e demanda espontânea (χ²=6,16; p=0,013). CONCLUSÃO: As diferenças evidenciadas em relação às características clínicas e epidemiológicas entre os municípios demonstram a dificuldade de controle da endemia em ambos os grupos de municípios.

Óbitos neonatais de recém-nascidos de baixo peso ao nascer / Neonatal deaths of low birth weight newborns

Analisar as principais características dos recém-nascidos de baixo peso ao nascer que foram a óbito em Cuiabá, Mato Grosso. Estudo a partir de uma coorte composta de nascidos vivos com peso ao nascer de 500-2499 gramas que evoluíram ao óbito antes de completarem 28 dias de vida. Os dados foram obtidos do Sistema de Informação sobre Nascidos Vivos e Sistema de Informação sobre Mortalidade. Dos 3.404 recém-nascidos estudados, 238 evoluíram para o óbito (7,0%). Prevaleceram os óbitos entre os do sexo masculino, com peso entre 500-999 gramas, Apgar < 7 no primeiro e no quinto minuto e com presença de anomalia congênita (p<0,001); com mães com idade menor que 20 anos (p=0,033); que realizaram de uma a seis consultas no pré-natal (p=<0,001). Os resultados mostraram que os óbitos neonatais se relacionaram com a qualidade da atenção obstétrica e neonatal, por se tratarem majoritariamente de mortes evitáveis.

A study conducted from a cohort composed of live infants with birth weight of 500 -2499 grams who progressed to death before completing 28 days of life. The data were obtained from the Live Births Information System and Mortality Information System. Of the 3,404 studied newborns, 238 progressed to death (7.0%). Prevalent deaths were among males, weighing between 500 and 999 grams, Apgar < 7 in the first and fifth minute with a congenital anomaly (p<0.001); with mothers younger than 20 years (p=0.033); who attended one to six prenatal appointments (p=<0.001). The results showed that neonatal deaths were related to the quality of obstetric and neonatal attention, as they were mostly avoidable deaths.

Hanseníase em menores de quinze anos em municípios prioritários, Mato Grosso, Brasil / Leprosy in individuals under the age of fifteen in priority cities, Mato Grosso, Brazil

RESUMO: Objetivos: Comparar as características sociodemográficas, clínicas e epidemiológicas de indivíduos menores de 15 anos notificados com hanseníase entre os municípios prioritários e os não prioritários, bem como a distribuição espacial destes casos registrados em tais municípios. Trata-se de um estudo transversal a partir de casos novos de hanseníase em menores de 15 anos (n=429) registrados no Sistema de Informação de Agravos de Notificação do estado de Mato Grosso, entre 2011 e 2013. Os casos diagnosticados foram comparados quanto aos aspectos sociodemográficos, clínicos e epidemiológico por meio do teste do qui-quadrado ao nível de significância de 5%. A distribuição espacial foi feita por meio do software ArcGis 10.2. Resultados: Dos 141 municípios do estado avaliados segundo a distribuição espacial, 58,1% (n=82) apresentaram coeficiente médio de incidência alto, muito alto e hiperendêmico, sendo que, destes, 34,1% (n=28) contemplam o grupo dos prioritários. Dos casos novos incluídos no estudo, 73,9% (n=317) foram notificados em municípios prioritários. Observou-se diferença na proporção de casos registrados entre os municípios, com maior proporção nos prioritários quanto à idade de 5 a 9 anos (χ²=4,09; p=0,043), raça branca (χ²=7,01; p=0,008) e forma clínica tuberculoide (χ²=3,89; p=0,048), e maior proporção nos não prioritários quanto à zona não urbana (χ²=24,23; p<0,001), duas a cinco lesões (χ²=5,93; p=0,014) e demanda espontânea (χ²=6,16; p=0,013). Conclusão: As diferenças evidenciadas em relação às características clínicas e epidemiológicas entre os municípios demonstram a dificuldade de controle da endemia em ambos os grupos de municípios.

ABSTRACT: Objectives: We aimed to compare the sociodemographic, clinical and epidemiological characteristics of individuals under the age of 15, reported to have leprosy, and who lived in priority and non-priority cities, as well as to compare the spatial distribution of these reported cases in such cities. This is a cross-sectional study of new leprosy cases in individuals under the age of 15 (n=429) registered in the Information System for Notifiable Diseases from the State of Mato Grosso, Brazil, between 2011 and 2013. The diagnosed cases were compared regarding sociodemographic, clinical and epidemiological aspects using the chi-square test at a 5% significance level. The spatial distribution was made through ArcGIS 10.2 software. Results: Of the 141 assessed cities in the state, according to the spatial distribution, 58.1% (n=82) showed a high, very high and hyper-endemic mean incidence coefficient, and, of these, 34.1% (n=28) include the group of priority municipalities. Of the new cases included in the study, 73.9% (n=317) were reported in priority cities. We observed a difference in the proportion of cases registered among the cities, with a greater proportion in priority cities, in the age group from five to nine years old (χ²=4.09; p=0.043), in the white race (χ²=7.01; p=0.008) and in the tuberculoid clinical form (χ²=3.89; p=0.048). There was a greater proportion in non-priority cases with regard to non-urban areas (χ²=24.23; p<0.001), two to five skin lesions (χ²=5.93; p=0.014) and spontaneous demand (χ²=6.16; p=0.013). Conclusion: The differences highlighted regarding clinical and epidemiological characteristics between the cities demonstrate the difficulty of endemic control in both municipality groups.

Effectiveness of rifampicin chemoprophylaxis in preventing leprosy in patient contacts: a systematic review of quantitative and qualitative evidence.

BACKGROUND: Individuals in contact with patients who have leprosy have an increased risk of disease exposure, which reinforces the need for chemoprophylactic measures, such as the use of rifampicin. OBJECTIVES: The objective of the review was to synthesize the best available evidence regarding the effectiveness of rifampicin chemoprophylaxis for contacts with patients with leprosy, and to synthesize the best available evidence on the experience and acceptability of rifampicin chemoprophylaxis as reported by the contacts and health professionals involved in the treatment of leprosy or Hansen's disease. INCLUSION CRITERIA TYPES OF PARTICIPANTS: In the quantitative component, individuals in contact with leprosy patients were included. In the qualitative component, in addition to contacts, health professionals who were in the practice of treating leprosy were included. TYPES OF INTERVENTION(S)/PHENOMENA OF INTEREST: The quantitative component considered as an intervention rifampicin at any dose, frequency and mode of administration, and rifampicin combination regimens.The qualitative component considered as phenomena of interest the experience and acceptability of rifampicin chemoprophylaxis. TYPES OF STUDIES: The quantitative component considered experimental and observational studies whereas the qualitative component considered studies that focused on qualitative data, including but not limited to, designs such as phenomenology, grounded theory, ethnography and action-research. OUTCOMES: The quantitative component considered studies that reported on outcomes such as the development of clinical leprosy in the contacts of patients who had leprosy, incidence rates, adverse effects and safety/harmful effects of the intervention. SEARCH STRATEGY: A three-step strategy for published and unpublished literature was used. The search for published studies included: PubMed, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, Scopus, Web of Science, National Institute for Health and Clinical Excellence, Latin American and Caribbean Health Sciences Literature; and Google Scholar and EVIPnet for unpublished studies. Studies published from the time of the respective database inception to January 2016 in English, Spanish, Portuguese, Japanese and Chinese were considered. METHODOLOGICAL QUALITY: Two reviewers independently assessed the studies for methodological quality using standardized critical appraisal instruments from the Joanna Briggs Institute. DATA EXTRACTION: Standardized data extraction tools developed by the Joanna Briggs Institute were used to extract quantitative and qualitative data from papers included in the review. DATA SYNTHESIS: Due to clinical and methodological heterogeneity in the interventions of the included studies, no statistical meta-analysis was possible. Quantitative and qualitative research findings are presented in narrative form. RESULTS: Following critical appraisal, eight studies were included in this review, seven quantitative and one qualitative. The reduction in incidence of leprosy, using one dose of rifampicin in the first two years, was 56.5%; in the follow up period of one to four years, the reduction was 34.9%. The combination of rifampicin and the Bacillus Calmette-Guérin vaccine showed a preventative effect of 80% against the disease. The only controlled clinical trial using two doses of rifampicin was community-based and did not indicate effectiveness of the intervention. The qualitative findings showed social acceptability of rifampicin. CONCLUSIONS: Chemoprophylaxis with one dose of rifampicin is found to be effective in preventing contacts of leprosy patients from contracting the disease. Also, there is indication that this strategy is socially accepted.

Trend of leprosy in individuals under the age of 15 in Mato Grosso (Brazil), 2001-2013.

OBJECTIVE: To identify the historical trend of leprosy epidemiological indicators in individuals under the age of 15 in the state of Mato Grosso. METHODS: Descriptive study with trend analysis of leprosy indicators in individuals under the age of fifteen registered in the Mato Grosso's System for Notifiable Diseases between 2001 and 2013. We used the Prais-Winsten procedure for analyzing generalized linear regression at a significance level of 5%. We considered as increasing time series when the annual percent change was positive, decreasing when negative and stationary when there was no significant difference between its value and zero. RESULTS: We analyzed 2455 cases of leprosy and the average detection rate in individuals under the age of fifteen was 22.7 per 100 thousand inhabitants. The trend of the general coefficient of incidence was decreasing, with an average annual rate of -5.5% (95%CI -7.5--3.5). Increasing trend was observed with an increase of 6.7% (95%CI 2.7-10.8) in the proportion of multibacillary cases, 9.4% (95%CI 4.4-14.7) of cases diagnosed with dimorphic clinical form and 14% (95%CI 7.9-20.4) of cases with physical disability level 2 at the time of diagnosis. There was an increasing trend in the average proportion of examined contacts, with a growth of 4.1% (95%CI 1.2-7.1) and average proportion of healing was precarious (39.7%), with stationary trend. CONCLUSIONS: The historical trend of leprosy cases in individuals under the age of fifteen proved to be decreasing in the period, however the trends of epidemiological indicators such as the proportion of multibacillary cases, physical disability level 2 and healing, indicate late diagnosis with stay sources of transmission and consequent worsening of the disease in the state of Mato Grosso. OBJETIVO: Identificar a tendência histórica dos indicadores epidemiológicos de hanseníase em menores de 15 anos no estado de Mato Grosso. MÉTODOS: Estudo descritivo com análise de tendência dos indicadores de hanseníase em menores de 15 anos registrados no Sistema Nacional de Agravos de Notificação de Mato Grosso, no período de 2001 a 2013. Utilizou-se o procedimento de Prais-Winsten para análise de regressão linear generalizada, adotando-se nível de significância de 5%. Consideraram-se como série temporal crescente quando a annual percent change era positiva, decrescente quando negativa e estacionária quando não havia diferença significante entre seu valor e o zero. RESULTADOS: Foram analisados 2.455 casos de hanseníase e o coeficiente médio de incidência em menores de 15 anos foi de 22,7/100 mil habitantes. A tendência geral do coeficiente de incidência foi decrescente, com uma annual percent change de -5,5% (IC95% -7,5-3,5). Observou-se tendência de crescimento, com incremento de 6,7% (IC95% 2,7-10,8) na proporção dos casos multibacilares, de 9,4% (IC95% 4,4-14,7) nos casos com forma clínica dimorfa e de 14% (IC95% 7,9-20,4) nos casos com incapacidade física grau 2 no momento do diagnóstico da doença. Verificou-se crescimento na proporção dos contatos de casos novos examinados, com incremento de 4,1% (IC95% 1,2-7,1) e média da proporção de cura considerada precária (39,7%) com tendência estacionária. CONCLUSÕES: A tendência histórica dos casos de hanseníase em menores de 15 anos mostrou-se decrescente no período. Entretanto, as tendências dos indicadores epidemiológicos, como a proporção de casos multibacilares, de incapacidade física grau 2 e de cura, indicam o diagnóstico tardio com permanência de fontes de transmissibilidade e consequente agravo da endemia no estado de Mato Grosso.
