Common mental disorders associated with tuberculosis: a matched case-control study.

INTRODUCTION: Despite the availability of treatment and a vaccine, tuberculosis continues to be a public health problem worldwide. Mental disorders might contribute to the burden of the disease. OBJECTIVE: The objective of this study was to investigate the association between common mental disorders and tuberculosis. METHODS: A matched case-control study was conducted. The study population included symptomatic respiratory patients who attended three referral hospitals and six community clinics in the city of Salvador, Brazil. A doctor's diagnosis defined potential cases and controls. Cases were newly diagnosed tuberculosis cases, and controls were symptomatic respiratory patients for whom tuberculosis was excluded as a diagnosis by the attending physician. Cases and controls were ascertained in the same clinic. Data collection occurred between August 2008 and April 2010. The study instruments included a structured interview, a self-reporting questionnaire for the identification of common mental disorders, and a questionnaire for alcoholism. An univariate analysis included descriptive procedures (with chi-square statistics), and a multivariate analysis used conditional logistic regression. RESULTS: The mean age of the cases was 38 years, and 61% of the cases were males. After adjusting for potential confounders, the odds of tuberculosis were significantly higher in patients diagnosed with a common mental disorder (OR: 1.34; 95% CI 1.05-1.70). CONCLUSION: There appears to be a positive and independent association between common mental disorders and tuberculosis; further epidemiological studies are required to increase our understanding of the possible biological and social mechanisms responsible for this association. Independent of the direction of the association, this finding has implications for the provision of care for mental disorders and for tuberculosis

Associação entre diabetes e tuberculose: estudo caso controle

OBJETIVO Testar a associação entre diabetes e tuberculose. MÉTODOS Trata-se de estudo caso-controle, pareado por idade e sexo. Foram incluídos 323 casos novos de tuberculose com resultados positivos à baciloscopia. Os controles foram 323 sintomáticos respiratórios com baciloscopia negativa, oriundos dos mesmos serviços de saúde dos casos: ambulatórios de três hospitais de referência e seis unidades básicas de saúde responsáveis pelas notificações dos casos novos de tuberculose em Salvador, Bahia. A coleta de dados ocorreu entre 2008 e 2010. Os instrumentos utilizados foram entrevista estruturada, incluindo dados clínicos, glicemia capilar (em jejum ou pós-prandial) e o questionário CAGE para triagem de consumo abusivo de álcool. Foi realizada análise descritiva, exploratória e multivariada utilizando-se de regressão logística condicional. RESULTADOS A média de idade dos casos foi 38,5 (DP = 14,2) anos e dos controles, 38,5 (DP = 14,3) anos. Tanto entre os casos quanto entre os controles, a maioria (61%) dos indivíduos era do sexo masculino. Na análise univariada, houve associação entre ocorrência de diabetes e de tuberculose (OR = 2,37; IC95% 1,04–5,42), que permaneceu estatisticamente significante após ajuste pelos potenciais confundidores (OR = 3,12; IC95% 1,12–7,94). CONCLUSÕES A associação entre diabetes e tuberculose pode dificultar o controle da tuberculose, contribuindo para manutenção da elevada carga da doença. A situação demanda intensificação da detecção precoce de diabetes entre pessoas com tuberculose, na tentativa de maior efetividade das estratégias de controle da doença.OBJECTIVE To test the association between diabetes and tuberculosis. METHODS It is a case-control study, matched by age and sex. We included 323 new cases of tuberculosis with positive results for bacilloscopy. The controls were 323 respiratory symptomatic patients with negative bacilloscopy, from the same health services, such as: ambulatory cases from three referral hospitals and six basic health units responsible for the notifications of new cases of tuberculosis in Salvador, Bahia. Data collection occurred between 2008 and 2010. The instruments used were structured interview, including clinical data, capillary blood glucose (during fasting or postprandial), and the CAGE questionnaire for screening of abusive consumption of alcohol. Descriptive, exploratory, and multivariate analysis was performed using conditional logistic regression. RESULTS The average age of the cases was 38.5 (SD = 14.2) years and of the controls, 38.5 (SD = 14.3) years. Among cases and controls, most subjects (61%) were male. In univariate analysis we found association between the occurrence of diabetes and tuberculosis (OR = 2.37; 95%CI 1.04–5.42), which remained statistically significant after adjustment for potential confounders (OR = 3.12; 95%CI 1.12–7.94). CONCLUSIONS The association between diabetes and tuberculosis can hinder the control of tuberculosis, contributing to the maintainance of the disease burden. The situation demands increasing early detection of diabetes among people with tuberculosis, in an attempt to improve disease control strategies

Radiologic findings of pulmonary tuberculosis in adolescents

AbstractObjectiveTo describe radiologic findings of pulmonary tuberculosis (TB) in adolescents.MethodsRetrospective, cross-sectional, observational study of 850 patients with TB, aged 10 to 19 years, and notified to the Brazilian Ministry of Health. Data were collected from the TB notification and medical records in the cities of Manaus, Amazonas State, and Salvador, Bahia State, in the 1996–2003 period. Data are shown in tables and analyzed using the chi-square and Mann-Whitney tests, with a 5% significance level.ResultsMean age was 15.6 years; 443 (52.1%) patients were males. The most common radiologic lesion was the upper pulmonary lobe infiltrate (53.3%), and isolated cavitation was found in 32.4% of the patients. Both lungs were affected in 29.2% of the patients. The finding of bilateral radiologic lesions was significantly associated with longer disease duration (p = 0.0005).ConclusionsPulmonary TB in adolescents has similar characteristics to TB in adults, evidencing the important role played by adolescents in community disease transmission

The need for fast-track, high-quality and low-cost studies about the role of the BCG vaccine in the fight against COVID-19.

Bacillus Calmette-Guérin (BCG) vaccination is routine and near-universal in many low- and middle-income countries (LMIC). It has been suggested that BCG can have a protective effect on COVID-19 morbidity and mortality. This commentary discusses the limitations of the evidence around BCG and COVID-19. We argue that higher-quality evidence is necessary to understand the protective effect of the BCG vaccine from existing, secondary data, while we await results from clinical trials currently conducted in different settings

Mycobiota of silk-faced ancient Mogao Grottoes manuscripts belonging to the Stein collection in the British library

Silking, a conservation technique which involved gluing silk gauze over the face of a manuscript was popular in the mid-20th Century, especially for treating early Chinese documents. The method is now little used, and the question as to whether silking interventions should be reversed is controversial, given the high economic cost of active intervention, and there are few scientific studies as to the long-term consequences of the technique. Silk-facing materials from documents of the Stein collection were analysed using scanning electron microscopy coupled with energy dispersive X-ray spectroscopy. The mycobiota diversity was unravelled through the combination of culture dependent methods and amplicon sequencing analyses. The SEM micrographs showed smooth regular nodules of ca. 3–5 μm diameter on both silk threads and glue paste. This morphology differs from the irregular and the crystalline morphologies of glue paste and inorganic crystallites, respectively, but it is consistent with that of small-sized conidia (asexual spores of fungi) or yeasts. Glue paste demonstrated three fungal strains: Aspergillus tubingensis, Penicillium crustosum and Chrysonilia sitophila which display cellulolytic activity, except for the last one. Amplicon sequencing revealed that silk threads and glue paste host distinct mycobiota. Here, we preliminary show that the silking method may be affecting the overall integrity of the silk-faced manuscripts, principally due to contamination with cellulolytic fungal strains. Unless the silk facing is removed, irreversible damage to the documents is highly probable

Tuberculose em adolescentes em duas capitais brasileiras

Analisamos o perfil clínico-radiológico da tuberculose (TB) em adolescentes de duas capitais brasileiras, segundo a revisão de 2010 das normas do Programa Nacional de Controle da Tuberculose; estudo descritivo, retrospectivo, transversal de casos notificados de TB em Manaus e Salvador, de 1996 a 2003, em dois grupos: 10 a 14 anos e &#8805; 15 a 19 anos com estatística descritiva. Havia 1.781 adolescentes [928 (52,1%) do sexo masculino]. A média de idade = 16 anos (mediana = 16; DP = 2,3). Encontramos 1.447 (82,9%) pacientes com TB pulmonar; 179 (10,3%) com TB pleural e 81 (4,6%) com ganglionar periférica. A tosse ocorreu mais no grupo &#8805; 15 anos (p < 0,001). A baciloscopia foi positiva em 150 (72,1%) com TB pulmonar no grupo de 10 a 14 anos, e em 870 (84,4%) no grupo de &#8805; 15 anos. Havia radiografias de tórax do tipo adulto em 1.088 (98.6%) no grupo de &#8805; 15 anos, e em 58 (98.1%) no grupo < 15 anos (p < 0.0001). Houve tendência à maior ocorrência de TB bacteriológica do tipo adulto na medida em que o paciente aumentava de idade
