Multidrug-resistant tuberculosis in South Korea: a retrospective analysis of national registry data in 2011-2015.

BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) poses a threat to public health as a result of high treatment costs and unsatisfactory outcomes.OBJECTIVE: To elucidate trend, demographic and clinical characteristics and treatment outcomes of patients with MDR-TB between 2011 and 2015 in South Korea.METHOD: Data of patients with MDR-TB diagnosed between 1 January 2011 and 31 December 2015 were retrieved from the nationwide Internet-based TB notification system and analysed retrospectively.RESULTS: During the study period, 5192 MDR-TB patients were notified. We identified an increasing number of MDR-TB patients among foreign populations (from 1.3% to 7.7%), decreasing resistance rates to other anti-TB drugs (e.g., resistance to pyrazinamide, from 40.9% to 28.2%), a decreasing interval from treatment initiation to negative conversion of sputum culture (from 165.7 to 103.7 days) and shortening of treatment duration (719.7 to 613.2 days). However, treatment success rates did not change, and had an average of 65.7%.CONCLUSION: Despite decreasing resistance rates to other drugs and faster treatment responses, treatment outcomes did not improve during the study period. Strict management of MDR-TB patients on treatment should be adopted to improve treatment outcomes.

[Tuberculosis in indigenous children and adolescents in Brazil: factors associated with death and treatment dropout]. / Tuberculose entre crianças e adolescentes indígenas no Brasil: fatores associados ao óbito e ao abandono do tratamento.

The study aimed to describe clinical and sociodemographic characteristics, estimate incidence, and analyze factors associated with dropout and death during treatment of TB cases reported in indigenous children and adolescents in Brazil from 2006 to 2016. A historical case series was performed on incidence according to age bracket and major geographic region, and multinomial logistic regression was used to explain factors associated with treatment dropout and death. Of the 2,096 reported cases, 88.2% evolved to cure, 7.2% dropped out of treatment, and 4.6% evolved to death. There was a predominance of cases in boys 15-19 years of age and a higher proportion of deaths (55.7%) in children < 4 years. Considering indigenous children and adolescents with TB in Brazil as a whole, mean incidence was 49.1/100,000, ranging from 21.5/100,000 to 97.6/100,000 in the Northeast and Central, respectively. Cases with insufficient and irregular follow-up showed higher odds of dropout (OR = 11.1; 95%CI: 5.2-24.8/OR = 4.4; 95%CI: 1.9-10.3) and death (OR = 20.3; 95%CI: 4.9-84.9/OR = 5.1; 95%CI: 1.2-22.7). Cases in retreatment (OR = 2.4; 95%CI: 2.08-8.55) and with HIV coinfection (OR = 8.2; 95%CI: 2.2-30.9) were also associated with dropout. Extrapulmonary (OR = 1.8; 95%CI: 1.1-3.3) and mixed clinical forms (OR = 5.6; 95%CI: 2.8-11.4), age < 4 years (OR = 3.1; 95%CI: 1.5-6.4), and cases from the North (OR = 2.8; 95%CI: 1.1-7.1) and Central (OR = 2.8; 95%CI: 1.1-7.0) were associated with death. TB control in indigenous children and adolescents cannot be achieved without investments in research and development and without reducing social inequalities.

O objetivo deste estudo foi descrever características clínicas e sociodemográficas, estimar a incidência da tuberculose (TB), além de analisar fatores associados ao abandono e ao óbito na vigência do tratamento dos casos de TB notificados entre crianças e adolescentes indígenas, no Brasil, entre 2006-2016. Realizou-se análise da série histórica de incidência, segundo faixa etária e macrorregião e utilizou-se regressão logística multinomial para elucidar fatores associados ao abandono e ao óbito. Do total de 2.096 casos notificados, 88,2% tiveram cura, 7,2% abandonaram o tratamento e 4,6% evoluíram para óbito. Houve predomínio de casos em meninos de 15-19 anos e maior proporção de óbitos (55,7%) em < 4 anos. Considerando o conjunto de crianças e adolescentes indígenas com TB no Brasil, a incidência média foi 49,1/100 mil, variando de 21,5/100 mil a 97,6/100 mil nas regiões Nordeste e Centro-oeste, respectivamente. Os casos com acompanhamento insuficiente e regular tiveram maiores chances de abandono (OR = 11,1; IC95%: 5,2-24,8/OR = 4,4; IC95%: 1,9-10,3) e óbito (OR = 20,3; IC95%: 4,9-84,9/OR = 5,1; IC95%: 1,2-22,7). Os casos em retratamento (OR = 2,4; IC95%: 2,08-8,55) e com anti-HIV positivo (OR = 8,2; IC95%: 2,2-30,9) também mostraram-se associados ao abandono. As formas clínicas extrapulmonar (OR = 1,8; IC95%: 1,1-3,3) e mista (OR = 5,6; IC95%: 2,8-11,4), os casos em < 4 anos (OR = 3,1; IC95%: 1,5-6,4) e os casos provenientes das regiões Norte (OR = 2,8; IC95%: 1,1-7,1) e Centro-oeste (OR = 2,8; IC95%: 1,1-7,0) mostraram-se associados ao óbito. Acreditamos que o controle da TB em crianças e adolescentes indígenas não poderá ser alcançado sem investimentos em pesquisa e desenvolvimento e sem a redução das desigualdades sociais.

Potential use of Western Australia's mandatory Midwives Notification System for routinely monitoring antenatal vaccine coverage

Background: Despite the maternal and infant health benefits of antenatal vaccines and availability of government-funded vaccination programs, Australia does not have a national system for routinely monitoring antenatal vaccination coverage. We evaluated the potential use of Western Australia's mandatory Midwives Notification System (MNS) as a tool for routinely monitoring antenatal vaccination coverage. Methods: Two hundred and sixty-eight women who gave birth to a live infant between August and October 2016 participated in a telephone survey of vaccines received in their most recent pregnancy. For women who reported receiving influenza and/or pertussis vaccine and whose vaccination status was documented by their vaccine provider, MNS vaccination data were compared with the vaccine provider's record as the 'gold standard.' For women who reported receiving no vaccines, MNS vaccination data were compared with self-reported information. Results: Influenza and pertussis vaccination status was complete (i.e. documented as either vaccinated or not vaccinated) for 66% and 63% of women, respectively. Sensitivity of MNS influenza vaccination data was 65.7% (95% CI 56.0-74.2%) and specificity was 53.0% (95% CI 42.4-63.4%). Sensitivity of MNS pertussis vaccination data was 62.5% (95% CI 53.3-70.9%) and specificity was 40.4% (95% CI 27.6-54.7%). There was no difference between vaccinated and unvaccinated women in the proportion of MNS records with missing or unknown vaccination information. When considering only MNS records with complete vaccination information, the sensitivity of the MNS influenza vaccination field was 91.8% (95% CI 83.0-96.9%) and the sensitivity of the MNS pertussis vaccination field was 88.0% (95% CI 76.7-95.5%). Conclusion: Due to the high proportion of records with missing or unknown vaccination status, we observed low sensitivity and specificity of antenatal vaccination data in the MNS. However, given we did not observe differential ascertainment by vaccination status, MNS records with complete information may be reliable data source for routinely monitoring antenatal vaccine coverage.

Control of paratuberculosis: who, why and how. A review of 48 countries.

Paratuberculosis, a chronic disease affecting ruminant livestock, is caused by Mycobacterium avium subsp. paratuberculosis (MAP). It has direct and indirect economic costs, impacts animal welfare and arouses public health concerns. In a survey of 48 countries we found paratuberculosis to be very common in livestock. In about half the countries more than 20% of herds and flocks were infected with MAP. Most countries had large ruminant populations (millions), several types of farmed ruminants, multiple husbandry systems and tens of thousands of individual farms, creating challenges for disease control. In addition, numerous species of free-living wildlife were infected. Paratuberculosis was notifiable in most countries, but formal control programs were present in only 22 countries. Generally, these were the more highly developed countries with advanced veterinary services. Of the countries without a formal control program for paratuberculosis, 76% were in South and Central America, Asia and Africa while 20% were in Europe. Control programs were justified most commonly on animal health grounds, but protecting market access and public health were other factors. Prevalence reduction was the major objective in most countries, but Norway and Sweden aimed to eradicate the disease, so surveillance and response were their major objectives. Government funding was involved in about two thirds of countries, but operations tended to be funded by farmers and their organizations and not by government alone. The majority of countries (60%) had voluntary control programs. Generally, programs were supported by incentives for joining, financial compensation and/or penalties for non-participation. Performance indicators, structure, leadership, practices and tools used in control programs are also presented. Securing funding for long-term control activities was a widespread problem. Control programs were reported to be successful in 16 (73%) of the 22 countries. Recommendations are made for future control programs, including a primary goal of establishing an international code for paratuberculosis, leading to universal acknowledgment of the principles and methods of control in relation to endemic and transboundary disease. An holistic approach across all ruminant livestock industries and long-term commitment is required for control of paratuberculosis.

Dietary Eriodictyol Alleviates Adiposity, Hepatic Steatosis, Insulin Resistance, and Inflammation in Diet-Induced Obese Mice.

The present study aimed to investigate the molecular mechanisms underlying the anti-obesity effect of flavonoid eriodictyol (ED) supplementation in mice fed with a high-fat diet (HFD). C57BL/6N mice were fed with normal diet (ND), HFD (40 kcal% fat), or HFD + 0.005% (w/w) ED for 16 weeks. In HFD-induced obese mice, dietary ED supplementation significantly alleviated dyslipidemia and adiposity by downregulating the expression of lipogenesis-related genes in white adipose tissue (WAT), while enhancing fecal lipid excretion. ED additionally improved hepatic steatosis and decreased the production of pro-inflammatory cytokines by downregulating the expression of hepatic enzymes and the genes involved in lipogenesis and upregulating the expression of hepatic fatty acid oxidation-related enzymes and genes. In addition, ED improved insulin resistance (IR) by suppressing hepatic gluconeogenesis, enhancing glucose utilization, and modulating the production and release of two incretin hormones, namely gastric inhibitory polypeptide (GIP) and glucagon-like peptide-1 (GLP-1). Taken together, the current findings indicated that ED can protect against diet-induced obesity and related metabolic disturbances, including dyslipidemia, inflammation, fatty liver disease, and IR in diet-induced obese mice.

El declive de la incidencia de enfermedad meningocócica en Barcelona entre 1988 y 2015: la influencia de la vacunación frente al serogrupo C / The decline of the incidence of meningococcal disease in Barcelona between 1988 and 2015: the influence of the vaccine against serogroup C

Introducción y objetivo: El objetivo es conocer la evolución de la enfermedad meningocócica en la ciudad de Barcelona entre 1988 y 2015 y evaluar el impacto de la vacuna contra el serogrupo C. Materiales y métodos: Se analizó la evolución de casos de enfermedad meningocócica y por serogrupo a partir del registro de enfermedades de declaración obligatoria. Se comparó la incidencia de todos los serogrupos antes y después de la introducción de la vacunación contra el serogrupo C en el año 2000. Se analizó la cobertura vacunal entre los casos, el serogrupo entre casos vacunados y la tasa de mortalidad y letalidad. Resultados: La enfermedad meningocócica ha pasado de una incidencia en menores de un año de 63,09 casos por 100.000 en 1997-2000 a 15,44 en 2001-2015. Todos los serogrupos han disminuido su incidencia tras la implementación vacunal, especialmente en niños de uno a 4 años para el C. A partir del 2000 la cobertura vacunal en los casos por este serogrupo era del 7,6% y en los afectos por el B era del 35,0% (p<0,01). De los vacunados, el 66,4% de los casos fue serogrupo B y un 5,2% fue C (p<0,01). La tasa global de letalidad y de mortalidad fue del 7,7% y del 0,19/100.000 respectivamente, sin cambios significativos en el tiempo en cuanto a la letalidad. Conclusiones: La incidencia por serogrupo C y también por B ha disminuido tras la vacunación sistemática contra el serogrupo C. La vacunación contra el serogrupo B podría reducir aún más esta grave enfermedad con una letalidad importante que no ha disminuido en todo el periodo

Introduction and objective: The purpose of this study was to describe the evolution of meningococcal disease (MD) in the city of Barcelona between 1988 and 2015 and to assess the impact of the vaccine against serogroup C. Materials and methodology: The evolution of MD and by serogroup was analysed using the information included in the mandatory notification diseases registry. Incidences of all serogroups between the periods of before and after the implementation of the serogroup C vaccine in 2000 were compared. Vaccination coverage among cases, serogroup among vaccinated cases and mortality and case fatality rates were analysed. Results: MD has evolved from an incidence rate in children aged under 1 of 63.09 cases per 100,000 in 1997-2000 to 15.44 per 100,000 in 2001-2015. All MD serogroups incidences decreased after the implementation of the vaccine, especially for serogroup C among children aged between 1 and 4. Since 2000 vaccine coverage in MD cases by this serogroup was 7.6% while in those affected by serogroup B it was 35.0% (p<.01). Among those vaccinated, 66.4% of cases were serogroup B and 5.2% were C (p<.01). Mortality and case fatality rates were 7.7% and 0.19/100,000 respectively, without significant changes in time regarding case fatality. Conclusions: Incidence caused by serogroups B and C has decreased after the systematic vaccination against serogroup C. Vaccination against serogroup B could further reduce the impact of this lethal disease which has not decreased during this period

Rabies control in Europe: an overview of past, current and future strategies.

Europe's step-by-step approach to tackling canine and wildlife-mediated rabies has proven that the disease can be controlled and eliminated at the animal source. A decade of development work and support by the European Union has resulted in a successful oral rabies vaccination campaign for foxes and raccoon dogs, and provided the blueprint for eliminating wildlife-mediated rabies. In this paper, the authors examine the historical stages of animal rabies control and its eventual elimination in parts of Europe, particularly Western Europe. In addition, they consider current control measures and predict future challenges, many of which are faced by the vast and sparsely populated, rabies-endemic areas of Eastern Europe.

L'approche par étapes appliquée en Europe pour combattre la rage canine ainsi que celle transmise par la faune sauvage a démontré que cette maladie peut être contrôlée et éliminée à sa source animale. La stratégie conçue et soutenue par l'Union européenne pendant une décennie s'est concrétisée par une campagne de vaccination antirabique orale des renards et des chiens viverrins qui a été couronnée de succès et constitue un modèle pour l'élimination de la rage transmise par les animaux sauvages. Les auteurs examinent le déroulement des étapes successives de la lutte contre la rage animale et de son élimination dans certaines régions européennes, en particulier en Europe occidentale. Ils examinent également les mesures actuelles de lutte et annoncent les difficultés auxquelles il faudra faire face à l'avenir, en particulier dans les vastes régions d'Europe orientale où la population est clairsemée et la rage endémique.

El método gradual (por etapas) aplicado en Europa para combatir la rabia canina y la transmitida por animales silvestres ha demostrado que es posible controlar y eliminar la enfermedad en su foco animal de origen. Diez años de trabajo de desarrollo y de apoyo de la Unión Europea desembocaron en una fructífera campaña de vacunación antirrábica oral de zorros y mapaches, convertida ahora en un modelo para eliminar la rabia transmitida por animales silvestres. Los autores repasan las etapas históricas de la lucha contra la rabia animal hasta su eliminación final en ciertas partes de Europa, en particular en Europa Occidental. Además, examinan las medidas de control vigentes y auguran futuras dificultades, muchas de ellas en las vastas zonas de Europa Oriental donde la población es escasa y dispersa y la rabia es endémica.

OzFoodNet quarterly report, 1 July to 30 September 2015.

The Australian Government Department of Health established the OzFoodNet network in 2000 to collaborate nationally to investigate foodborne disease. In each Australian state and territory, OzFoodNet epidemiologists investigate outbreaks of enteric infection. In addition, OzFoodNet conducts studies on the burden of illness and coordinates national investigations into outbreaks of foodborne disease. This quarterly report documents investigations of outbreaks of gastrointestinal illness and clusters of disease potentially related to food, which commenced in Australia between 1 July and 30 September 2015.

Accelerating TB notification from the private health sector in Delhi, India.

INTRODUCTION: In India, almost half of all patients with tuberculosis (TB) seek care in the private sector as the first point of care. The national programme is unable to support such TB patients and facilitate effective treatment, as there is no information on TB and Multi or Extensively Drug Resistant TB (M/XDR-TB) diagnosis and treatment in private sector. OBJECTIVE: To improve this situation, Government of India declared TB a notifiable disease for establishing TB surveillance system, to extend supportive mechanism for TB treatment adherence and standardised practices in the private sector. But TB notification from the private sector is a challenge and still a lot needs to be done to accelerate TB notification. METHODS: Delhi State TB Control Programme had taken initiatives for improving notification of TB cases from the private sector in 2014. Key steps taken were to constitute a state level TB notification committee to oversee the progress of TB notification efforts in the state and direct 'one to one' sensitisation of private practitioners (PPs) (in single PP's clinic, corporate hospitals and laboratories) by the state notification teams with the help of available tools for sensitising the PP on TB notification - TB Notification Government Order, Guidance Tool for TB Notification and Standards of TB Care in India. RESULTS: As a result of focussed state level interventions, without much external support, there was an accelerated notification of TB cases from the private sector. TB notification cases from the private sector rose from 341 (in 2013) to 4049 (by the end of March 2015). CONCLUSION: Active state level initiatives have led to increase in TB case notification.

Surveillance of imported hospital requiring malaria in Portugal: can it be improved?

Although eradicated in Portugal, malaria keeps taking its toll on travellers and migrants from endemic countries. Completeness of hospital requiring malaria notification in Portugal 2000-11 was estimated, using two-source capture-recapture method. Data sources were: national surveillance database of notifiable diseases and the national database of the Diagnosis-Related Groups resulting from National Health Service (NHS) hospital episodes. The completeness of notification was 21,2% for all malaria cases and 26,5% for malaria deaths, indicating significant underreporting and urging for complementary data source in surveillance, for disease burden estimates and retrospective monitoring, namely hospital episodes statistics.

Lessons learned from initial reporting of carbapenem-resistant Enterobacteriaceae in New York State hospitals, 2013-2014.

BACKGROUND: Carbapenem-resistant Enterobacteriaceae (CRE) are an urgent concern in health care in the United States because of high attributable mortality and versatile resistance mechanisms. CRE reporting was mandated in New York State (NYS) hospitals in July 2013. METHODS: Infection preventionists from the NYS Department of Health audited hospital-reported CRE data by comparing laboratory records with cases reported to the National Healthcare Safety Network (NHSN). Information regarding microbiology laboratory testing methodologies was obtained through a survey in October 2013. RESULTS: There were 1,151 CRE laboratory reports audited, with 13.6% determined not to have been reported to the NHSN when they should have been and 4.6% determined to be reported in error. There were a variety of errors, including lapses in surveillance and misinterpretation of the surveillance definition. CONCLUSION: Educational initiatives that include microbiology laboratory staff, improvements in the use of laboratory information systems to communicate with infection prevention, and updated NHSN definitions should improve the accuracy and consistency of CRE reporting in NYS.

Sri Lankan National Melioidosis Surveillance Program Uncovers a Nationwide Distribution of Invasive Melioidosis.

The epidemiologic status of melioidosis in Sri Lanka was unclear from the few previous case reports. We established laboratory support for a case definition and started a nationwide case-finding study. Suspected Burkholderia pseudomallei isolates were collated, identified by polymerase chain reaction assay, referred for Matrix Assisted Laser Desorption Ionization-Time of Flight analysis and multilocus sequence typing (MLST), and named according to the international MLST database. Between 2006 and early 2014, there were 32 patients with culture-confirmed melioidosis with an increasing annual total and a falling fatality rate. Patients were predominantly from rural communities, diabetic, and male. The major clinical presentations were sepsis, pneumonia, soft tissue and joint infections, and other focal infection. Burkholderia pseudomallei isolates came from all parts of Sri Lanka except the Sabaragamuwa Province, the south central hill country, and parts of northern Sri Lanka. Bacterial isolates belonged to 18 multilocus sequence types, one of which (ST 1137) was associated with septicemia and a single-organ focus (Fisher's exact, P = 0.004). Melioidosis is an established endemic infection throughout Sri Lanka, and is caused by multiple genotypes of B. pseudomallei, which form a distinct geographic group based upon related sequence types (BURST) cluster at the junction of the southeast Asian and Australasian clades.

Multidrug-resistant tuberculosis in the Northern Territory: A 10-year retrospective case series.

BACKGROUND AND OBJECTIVE: To describe the clinical characteristics, risk factors, diagnostic modalities, treatments, subsequent outcomes and complications of Multidrug-resistant tuberculosis (MDR-TB) cases residing in the Northern Territory. METHODS: A retrospective case series was conducted of all patients treated for MDR-TB in the Northern Territory between 1 January 2004 and 31 December 2013. This is the first study to analyse data relating to the subset of MDR-TB cases treated in the Northern Territory. Cases were identified by the Northern Territory Centre for Disease Control (NT CDC): the public health unit responsible for the management of tuberculosis in the Northern Territory. Outcome measures included patient demographics, diagnostics, HIV status, treatment methods, outcomes, and complications. RESULTS AND CONCLUSIONS: Six MDR-TB cases were treated in the Northern Territory; 5 of these were notified by the NT CDC during the study period (1.5% of all Northern Territory TB notifications). The median age of all 6 patients was 31 years (range 21 to 50 years), sex distribution was equal and all were born overseas. Country of birth in a World Health Organization (WHO) high burden MDR-TB country and previous treatment were most highly correlated with a current diagnosis of MDR-TB. Access to rapid drug susceptibility testing reduced the time to effective therapy from 45 to 27 days. Five patients met criteria for the WHO outcome term 'treatment success'. The median length of treatment for the 5 patients treated in Australia was 623 days (537 to 730 days). Side effects to therapy were common and serious. The incidence of MDR-TB in the Northern Territory is similar to other Australian states. Rapid drug susceptibility testing reduces the time to effective therapy. Treatment regimens are complex, toxic and have serious resource implications for health care providers. Successful treatment outcomes are possible with coordinated TB control programs.

A violência contra crianças e adolescentes e a notificação compulsória, no âmbito da saúde, como mecanismo de proteção social / Violence against children and adolescents and compulsory notification within the health scenario as a mechanism for social protection

O artigo aborda o fenômeno da violência contra crianças e adolescentes, evidenciando o papel do Sistema Nacional de Informações aos Agravos de Notificação como um instrumento criado no âmbito da Política de Saúde. Realiza-se um estudo a partir dos dados notificados no município de Porto Alegre, no Rio Grande do Sul, no sul do Brasil, entre 2011 e 2013, através de uma abordagem analítica descritiva das notificações de violência infantojuvenil. Os resultados demonstram a totalização dos casos registrados no período do estudo e apresentam os indicadores sobre a natureza da violência, o perfil de crianças e adolescentes vítimas de violência, as unidades de saúde notificadoras, bem como os encaminhamentos à rede de proteção social. Conclui-se que a efetivação do instrumento de notificação constitui-se em um mecanismo de garantia dos direitos das crianças e adolescentes vítimas de violência, levando ao atendimento integral pela rede de proteção social das crianças, dos adolescentes e de suas famílias.

This article addresses the phenomenon of violence against children and adolescents, highlighting the role of Brazilian Information System for Notifiable Diseases as an instrument created in the Health Policy area. A study is performed based on data recorded in the city of Porto Alegre, in Rio Grande do Sul, south of Brazil, between 2011 and 2013, through a descriptive analytical approach of reports on child and juvenile violence. The results show the total number of cases recorded during the studied period and present the indicators on the nature of violence, the profile of children and adolescents who are victims of violence, the reporting health units, as well as the referrals to the social protection network. It is concluded that the instrument used for referral is a mechanism to guarantee the rights of children and adolescents who are victims of violence, guiding children, adolescents and their families to the comprehensive care provided by the social protection network.

Injuries caused by aquatic animals in Brazil: an analysis of the data present in the information system for notifiable diseases.

INTRODUCTION: We present a review of injuries in humans caused by aquatic animals in Brazil using the Information System for Notifiable Diseases [ Sistema de Informação de Agravos de Notificação (SINAN)] database. METHODS: A descriptive and retrospective epidemiological study was conducted from 2007 to 2013. RESULTS: A total of 4,118 accidents were recorded. Of these accidents, 88.7% (3,651) were caused by venomous species, and 11.3% (467) were caused by poisonous, traumatic or unidentified aquatic animals. Most of the events were injuries by stingrays (69%) and jellyfish (13.1%). The North region was responsible for the majority of reports (66.2%), with a significant emphasis on accidents caused by freshwater stingrays (92.2% or 2,317 cases). In the South region, the region with the second highest number of records (15.7%), jellyfish caused the majority of accidents (83.7% or 452 cases). The Northeastern region, with 12.5% of the records, was notable because almost all accidents were caused by toadfish (95.6% or 174 cases). CONCLUSIONS: Although a comparison of different databases has not been performed, the data presented in this study, compared to local and regional surveys, raises the hypothesis of underreporting of accidents. As the SINAN is the official system for the notification of accidents by venomous animals in Brazil, it is imperative that its operation be reviewed and improved, given that effective measures to prevent accidents by venomous animals depend on a reliable database and the ability to accurately report the true conditions.

A survey to assess the extent of public-private mix DOTS in the management of tuberculosis in Zambia.

BACKGROUND: Involving all relevant healthcare providers in tuberculosis (TB) management through public-private mix (PPM) approaches is a vital element in the World Health Organization's (WHO) Stop TB Strategy. The control of TB in Zambia is mainly done in the public health sector, despite the high overall incidence rates. AIM: We conducted a survey to determine the extent of private-sector capacity, participation, practices and adherence to national guidelines in the control of TB. SETTING: This survey was done in the year 2012 in 157 facilities in three provinces of Zambia where approximately 85% of the country's private health facilities are found. METHODS: We used a structured questionnaire to interview the heads of private health facilities to assess the participation of the private health sector in TB diagnosis, management and prevention activities. RESULTS: Out of 157 facilities surveyed, 40.5% were from the Copperbelt, 4.4% from Central province and 55.1% from Lusaka province. Only 23.8% of the facilities were able to provide full diagnosis and management of TB patients. Although 47.4% of the facilities reported that they do notify their cases to the National TB control programme, the majority (62.7%) of these facilities did not show evidence of notifications. CONCLUSION: Our results show that the majority of the facilities that diagnose and manage TB in the private sector do not report their TB activities to the National TB Control Programme (NTP). There is a need for the NTP to improve collaboration with the private sector with respect to TB control activities and PPM for Directly Observed Treatment, Short Course (DOTS).

Supplemental use of an interferon-gamma release assay in a state-wide tuberculosis contact tracing program in Victoria: a six-year review.

INTRODUCTION: Tuberculin skin testing (TST) has been the accepted Australian standard for investigating contacts following exposure to infectious tuberculosis (TB). In recent years, the availability of the interferon-gamma release assays (IGRA) has introduced a potential alternative test but data on its use in this context are limited. METHODS: A prospective longitudinal cohort study was conducted from 2008-2013 to review the use of IGRA and subsequent TB disease following testing in a state-wide contact tracing program. Additional information on the experience and acceptability of IGRA in this context was also obtained through program staff surveys following implementation. RESULTS: IGRA testing was performed on 643 contacts, with a mean follow-up of 3.7 years. IGRA was primarily used to supplement TST, most commonly due to borderline TST reactivity in individuals who had bacille Calmette-Guérin vaccination. Where both TST and IGRA were performed, correlation of test results was poor (kappa=0.35). The negative predictive value for later development of active TB was 99.5%. CONCLUSIONS: Our experience suggests that IGRA are able to be incorporated safely and effectively as a supplement to TST-based contact tracing.

Chinese Social Media Reaction to Information about 42 Notifiable Infectious Diseases.

This study aimed to identify what information triggered social media users' responses regarding infectious diseases. Chinese microblogs in 2012 regarding 42 infectious diseases were obtained through a keyword search in the Weiboscope database. Qualitative content analysis was performed for the posts pertinent to each keyword of the day of the year with the highest daily count. Similar posts were grouped and coded. We identified five categories of information that increased microblog traffic pertaining to infectious diseases: news of an outbreak or a case; health education/information; alternative health information/Traditional Chinese Medicine; commercial advertisement/entertainment; and social issues. News unrelated to the specified infectious diseases also led to elevated microblog traffic. Our study showcases the diverse contexts from which increased social media traffic occur. Our results will facilitate better health communication as causes underlying increased social media traffic are revealed.
