Decline of tuberculosis notification rate in different populations and regions in Portugal, 2010-2017.

BACKGROUND: Tuberculosis (TB) incidence declined in Portugal in recent decades, but trends differ between regions and population subgroups. We investigated these differences to inform prevention and control programmes. METHODS: We extracted TB notifications from the Portuguese National TB Surveillance System (SVIG-TB) in 2010-2017, disaggregated by region, age group, nationality and HIV status. We calculated notification rates using denominators from the Portuguese National Institute of Statistics and the Joint United Nations Programme on HIV/AIDS and performed stratified time series analysis. We estimated interannual decline percentages and 95% confidence intervals (CI) using Poisson and binomial negative regression models. RESULTS: The overall TB notification rate decreased from 25.7 to 17.5/100,000 population from 2010 to 2017 (5.2%/year) in Portugal. Interannual decline did not differ significantly between regions, but it was smaller amongst non-Portuguese nationals (-1.57% [CI: -4.79%, 1.75%] vs -5.85% [CI: -6.98%, -4.70%] in Portuguese nationals); children under five years of age (+1.77% [CI: -4.61%, 8.58%] vs -5.38% [CI: -6.33%, -4.42%] in other age groups); and HIV-negative people (-6.47% [CI: -9.10%, -3.77%] vs -11.29% [CI; -17.51%, -4.60%] in HIV-positive). CONCLUSIONS: The decline in TB notification rates in Portugal during the study period has been steady. However, the decline amongst non-Portuguese nationals, children under five years of age and non-infected-HIV patients was lower. No significant differences were observed between regions. Changes in TB epidemiology in specific risk groups and geographical areas should be closely monitored to achieve the objectives of the End TB Strategy. We recommend intensifying screening of TB in the subpopulations identified.

A Case Series of X-Linked Deafness-2 with Sensorineural Hearing Loss, Stapes Fixation, and Perilymphatic Gusher: MR Imaging and Clinical Features of Hypothalamic Malformations.

X-linked deafness-2 (DFNX2) is an X-linked recessive disorder characterized by profound sensorineural hearing loss and a pathognomonic temporal bone deformity. Because hypothalamic malformations associated with DFNX2 have been rarely described, we aimed to further describe these lesions and compare them with features of a nonaffected population. All patients diagnosed with DFNX2 between 2006 and 2019 were included and compared with age-matched patients with normal MR imaging findings and without hypothalamic dysfunction. MR imaging features differing between groups were selected to help identify DFNX2. Sensitivity and specificity were calculated for these features. Agreement among 3 radiologists was quantified using the index κ. Information on the presence or absence of gelastic seizures, precocious puberty, or delayed puberty was also gathered. We selected distinctive MR imaging features of hypothalamic malformations in DFNX2. The feature selected on axial T2 images was the folded appearance of the ventromedial hypothalamus (sensitivity, 100%; specificity, 95.8%) characterized by an abnormal internal/external cleft (sensitivity, 100%; specificity, 95.7%). On coronal T2, the first distinctive feature was a concave morphology of the medial eminence (sensitivity, 100%; specificity, 97.1%), the second feature was at least 1 hypothalamic-septum angle ≥90° (sensitivity, 90%; specificity, 72.5%), and the third feature was a forebrain-hypothalamic craniocaudal length of ≥6 mm (sensitivity, 70%; specificity, 79.7%). Clinical features were also distinctive because 9 patients with DFNX2 did not present with gelastic seizures or precocious puberty. One patient had delayed puberty. The κ index and intraclass correlation coefficient ranged between 0.78 and 0.95. Imaging and clinical features of the hypothalamus suggest that there is a hypothalamic malformation associated with DFNX2. Early assessment for pubertal delay is proposed.

[Factors that influence compliance with hand hygiene in healthcare professionals: A concept mapping study]. / Factores que influyen en el cumplimiento de la higiene de manos en profesionales sanitarios: un estudio de mapeo de conceptos.

OBJECTIVE: To identify factors that may influence hand hygiene compliance by professional category and clinical department. MATERIALS AND METHODS: Use was made of concept mapping methodology, a tool that combines a qualitative analysis with a quantitative statistical analysis, in order to identify the most influential and important factors for the fulfilment of hand hygiene in 2 clinical departments (Infectious and General Surgery) of the Hospital del Mar. RESULTS: The study included a total of 42 volunteer professionals from General Surgery (6 doctors and 10 nurses) and from Infectious Diseases (11 doctors and 10 nurses) clinical departments, as well as 5 hospital porters. High correlations of influential and important factors for hand hygiene compliance were observed between nurses and doctors in the Infectious Diseases Department (r=0.93 vs. r=0.69, respectively). In contrast, the correlation was lower among surgical professionals (r=-0.17 for influence and r=0.51 for importance). Professionals identified the most influential factors in compliance as training and adequate resources, taking into account professional category and clinical department. CONCLUSION: The design of interventions to improve compliance with hand hygiene should take into account the perceptions of different professionals in order to adapt actions to each professional group.

Impact of socio-economic inequities on tuberculosis in a Southern European city: what is the effect of the recession?

INTRODUCTION: Economic crises affect a population's health, particularly among the most deprived. The increase in health inequalities in the latest recession may have influenced the incidence of tuberculosis (TB). We analysed the effect of socio-economic inequities and recession on TB incidence in Barcelona, Spain. METHODS: We conducted a population-based incidence study of TB cases in Barcelona of patients who started treatment between 2003 and 2015. A multilevel interrupted time-series analysis was performed to analyse differences in incidence trends between the pre-recession (until 2008) and recession periods. RESULTS: We found differences in TB incidence according to deprivation and immigration status. TB incidence among the most deprived neighbourhoods was 2.72 times higher than the least deprived neighbourhoods. Compared with native-born persons, incidence was nine times higher among those born in Africa, and six times higher among those born in Asia and Oceania. The previous decreasing trend in incidence (4%) was accentuated during the recession (7%). CONCLUSIONS: TB incidence decreased during the recession, probably due to a reduction in the number of new immigrants and the TB programme. However, incidence was highly unequal between districts with different levels of deprivation, and between foreign-born persons from different geographic regions. Social measures are important to reduce inequalities and TB incidence in Barcelona.
