BACKGROUND Diabetes mellitus (DM) can contribute to the development of tuberculosis (TB). OBJECTIVE To analyse the prevalence of DM and its associated factors among adults with TB in a large city in an industrialised country. METHODS This is a population-based study in adults diagnosed with TB between 2000 and 2013 in Barcelona. We studied potentially(More)
During a 2-year period (2003-2004), tuberculosis (TB) transmission in Barcelona and the factors related to transmission among the Spanish- and foreign-born populations were studied by molecular epidemiology. Data were obtained from TB cases and Conventional Contact Tracing registries and genotyping was performed using restriction fragment length(More)
BACKGROUND Little is known about recurrent tuberculosis (TB) in developed countries. The objective of this study was to determine the probability of TB recurrence and the associated risk factors among cured patients in a city with moderate TB incidence. METHODS A population-based retrospective longitudinal study was carried out in Barcelona, Spain. All(More)
BACKGROUND Mortality among patients who complete tuberculosis (TB) treatment is still high among vulnerable populations. The objective of the study was to identify the probability of death and its predictive factors in a cohort of successfully treated TB patients. METHODS A population-based retrospective longitudinal study was performed in Barcelona,(More)
The objective of the study was to examine the factors associated with unidentified tuberculosis (TB) index cases (1987-2007) and to describe outbreaks (2000-2007) of childhood TB cases in Barcelona, Spain. Contact tracing seems to be fundamental in index case identification, but improvement could be made among older children and cases of extrapulmonary TB(More)
OBJECTIVE To study the prevalence of latent tuberculosis infection (LTBI) in prisoners. METHODS Among inmates admitted to a men's preventive detention prison in Barcelona during May-June 2009, without a previous positive tuberculin skin test (TST), a ≥ 10 mm TST was considered positive (5 mm in human immunodeficiency virus [HIV] infected persons). A(More)
BACKGROUND The important increase in immigration during recent years has changed the epidemiology and control strategies for tuberculosis (TB) in many places. This study evaluates the effectiveness of intervention with community health workers (CHW) to improve contact tracing among immigrants. METHODS The study included all TB cases detected by the(More)
Tuberculosis (TB) has affected humanity since the beginning of the recorded time and is associated with poverty, malnutrition, overcrowding, and immunosuppression. Since Koch discovered the infectious nature of the disease in 1882, knowledge about its history and physiopathology has advanced, but it continues to be a global public health problem. More than(More)
In low-incidence countries in the European Union (EU), tuberculosis (TB) is concentrated in big cities, especially among certain urban high-risk groups including immigrants from TB high-incidence countries, homeless people, and those with a history of drug and alcohol misuse. Elimination of TB in European big cities requires control measures focused on(More)
STUDY OBJECTIVE This study aimed to investigate the behaviour of two indicators of influenza activity in the area of Barcelona and to evaluate the usefulness of modelling them to improve the detection of influenza epidemics. DESIGN Descriptive time series study using the number of deaths due to all causes registered by funeral services and reported cases(More)
