Effective treatment of tuberculosis (TB) remains a serious public health problem in many countries, including Brazil, especially when considering drug-resistant disease. Xpert MTB/RIF has been implemented in many countries to reduce the time to TB diagnosis and to rapidly detect rifampicin resistance. The study aimed to describe and evaluate Xpert MTB/RIF performance in diagnosing pulmonary TB and rifampicin resistance in a tertiary healthcare facility in Brazil.A cross-sectional study was performed, which included all isolates of confirmed pulmonary TB patients from 2015 to 2018. Both Xpert MTB/RIF and GenoType MTBDRplus assays were performed to detect rifampicin and isoniazid resistance. In addition, isolates with detected resistance to rifampicin and/or isoniazid were analysed by phenotypic testing using MGIT-960 SIRE kit and whole-genome sequencing (WGS) using Illumina MiSeq Sequencing System.2148 respiratory specimens tested with Xpert MTB/RIF were included: n=1556 sputum, n=348 bronchoalveolar lavage and n=244 gastric washing. The overall Xpert MTB/RIF sensitivity in sputum was 94% and the overall specificity was 98%. The negative predictive value in sputum of all the patients was 99% with a positive predictive value of 89%. The concordance between Xpert MTB/RIF and phenotypic susceptibility test was 94.1%, while its concordance with WGS was 78.9%.Xpert MTB/RIF is a rapid and accurate diagnostic strategy for pulmonary TB, which can contribute to improvement in TB control. However, detection of rifampicin resistance might be associated with false-positive results.

Background: Stroke is a great public health problem in Ethiopia. According to reports, in-hospital stroke mortality was estimated to be 14.7% in Ethiopia. Despite this, in this country researches done on factors associated with stroke sub-types were inadequate. Objective: To assess the Characteristics and risk factors associated with stroke sub-types among patients admitted to JUMC. Methods and materials: A retrospective cross sectional study was conducted from May 2017 to May 2018 in stroke unit of Jimma University Medical Center. A total of 106 medical charts of patients diagnosed with stroke were reviewed. Checklist comprising of relevant variables was used to collect data. SPSS version 21 was employed for data entry and analysis. Chi-square test was used to point-out association and difference among stroke sub-types. The data was presented using text, tables and figures. Result: From a total of 106 patients, 67(63.2%) were men. The mean ± SD of age was 52.67±12.46 years, and no significant association was found. Of all the patients, 59(55.6%) had ischemic strokes and 47(44.4%) had hemorrhagic strokes. The most common risk factor in the patients was alcohol use with a prevalence of 69.9%. Of all the risk factors, only sex, cigarettes smoking and dyslipidemia were significantly associated to sub-types of stroke. Conclusion: Ischemic stroke was the most common subtype of stroke. Sex of patient, cigarette smoking and dyslipidemia are significantly associated with the two stroke subtypes.

Migrant Groups

Abstract Background In March 2017, Togo was declared the first country in sub-Saharan Africa to eliminate lymphatic filariasis as a public health problem, but post-validation surveillance has been lacking. In some areas of the country, migrant groups from neighboring countries that are still endemic for LF pose a risk of reintroduction of LF to Togo. The objective of this study was to identify the risk posed by migrant groups by measuring their prevalence of LF infection and investigating any positive case using Togo’s case investigation algorithm to prevent resurgence of LF and sustain Togo’s elimination success. Method A cross-sectional study was conducted in 2018 in the northernmost region of the country. Three migrant populations were identified: (i) nomadic Peuhls, (ii) Togolese members of local communities who migrate annually to neighboring countries for seasonal labor, and (iii) refugees from Ghana who came to Togo because of a communal conflict in Ghana. A questionnaire was designed to collect data on demographics and history of LF and MDA; all participants were tested for circulating filariasis antigen (CFA) using the filariasis test strip (FTS). Any CFA-positive case was confirmed with nocturnal microfilaremia. Results Refugees, seasonal economic migrants and nomadic Peuhls represented 42.1%, 31.4% and 26.5% of the study participants, respectively. The overall prevalence of CFA was 4.2% (58/1391) with the highest prevalence in the nomadic Peuhl group (11.9%), but only one of them (0.07%) was confirmed positive with nocturnal microfilaremia. Using the case investigation algorithm, no other positive case was identified in the positive case’s surroundings. Conclusion This study demonstrates that nomadic Peuhls, with a CFA prevalence of 11.9%, pose a potential risk for reintroduction of LF into Togo while Ghanaian refugees and seasonal economic migrants do not appear to pose a significant risk. Periodic monitoring of migrants, especially the nomadic Peuhl population, is a potential post-validation surveillance approach that could be used to promptly detect any LF cluster that may arise.

The Impact

Background: Myopia is a public health problem, with estimations that 50% of the world population will be myopic by 2050. Some environmental factors, such as time spent outdoors, doing near work, and using digital devices, influence the development of myopia in children. Home confinement in Spain has increased these risk factors, so this study aims to investigate the impact of home confinement during the COVID-19 outbreak in the vision of school-aged children; Methods: A cross-sectional study in children between 5 and 7 years old that completed a visual screening and a questionnaire about their lifestyles at opticians in Spain in September and October of 2019 and 2020. Statistical analysis to compare lifestyles pre and post confinement, and vision in 2020 versus a similar cohort examined at the same opticians in 2019, was conducted; Results: Spanish children spent less time outdoors and more time doing near work in 2020 than in 2019 (p ≤ 0.001). There was a significant decrease of the spherical equivalent (mean ± standard deviation; 0.66 ± 2.03 D in 2019 vs. 0.48 ± 1.81 D in 2020; p ≤ 0.001); Conclusions: Lifestyles of Spanish children changed during the home confinement at the beginning of 2020. Together with changes in their lifestyles, spherical equivalents have decreased, which implies higher figures of myopia for children aged between 5 and 7.

Community violence (CV) is a global public health problem due to its high frequency and severe consequences. Although CV is one of the leading causes of death among adolescents, little is known about the everyday CV situations that do not lead to death. This study aimed to estimate the frequency of exposure to and involvement in CV situations among adolescent students from public and private schools in the city of Rio de Janeiro, Brazil. This was a cross-sectional study of 693 individuals in their second year of high school selected through stratified multistage random sampling. Information about their exposure to and involvement in CV was collected through a self-completed multidimensional questionnaire in the classrooms. For approximately 30% of the adolescents, someone close to them had been murdered, and 40% had already seen the corpse of a victim of homicide. Seventeen percent reported having been directly involved in CV situations. Approximately 38%, 13%, and 25% had been victims of robberies, interpersonal aggression, and death threats to either themselves or their relatives, respectively. Many of these situations occurred more than once. In general, CV was more frequently reported by boys and by those who did not live with both parents. Adolescents from higher economic classes experienced more interpersonal aggression and felt a greater need to carry a gun. Those who belonged to the lower economic classes and studied in public schools were more exposed to lethal violence than other students. The results call attention to the very high percentage of adolescent students that are involved in CV situations as well as to the differences in violence rates among population subgroups. Such findings should be considered when planning CV prevention and management actions in schools and other socialization spaces for adolescents.

Childhood obesity is a public health problem with multiple effects on children’s life. Promoting Active School Travel (AST) could provide an inclusive opportunity for physical activity and shape healthy behaviours. Data for this cross-sectional study were drawn from questionnaires carried out in five primary schools located in Newcastle upon Tyne, UK, in neighbourhoods chosen for their variability in IMD (index of multiple deprivation) and spatial structure of street networks (measured through space syntax measure of integration). A randomly selected and heterogenic sample of 145 pupils (aged 9–10) completed an open-ended questionnaire to state what they like and dislike about their journey to school. Thematic analysis identified four typologies (environmental context, emotions, social influences and trip factors) based on the Theoretical Domains Framework (TDF) and specific themes and sub-themes underlying children’s affective experiences of their journeys to school. This study is the first known to authors to attempt to adapt the Capability, Opportunity and Motivation Behaviour (COM-B) model into AST and children’s experiences and associated behavioural domains with design aspects. Such an insight into children’s attitudes could inform urban planners and designers about how to apply more effective behaviour change interventions, targeting an AST increase among children.

Abstract Introduction Tuberculosis (TB) in people living with human immunodeficiency virus (PLHIV) is difficult to diagnose due to fewer organisms in sputum and extrapulmonary samples. Sputum culture takes 4 to 8 weeks for growth of the mycobacteria. Delayed treatment for TB in PLHIV leads to increased mortality. This study evaluated cartridge-based nucleic acid amplification test (CBNAAT) as a diagnostic tool for diagnosis of pulmonary TB (PTB) and extrapulmonary TB (EPTB) in PLHIV in the second most HIV prevalent state in India and for comparing its efficacy between Ziehl–Neelsen (ZN) staining sputum smear–positive and sputum smear–negative TB. Methods This cross-sectional study was conducted in RIMS, Imphal, with 167 PLHIV patients, age 15 years or older, having signs and symptoms of TB. Appropriate samples for sputum microscopy and CBNAAT were sent. Conclusion The overall sensitivity of sputum smear for acid-fast bacillus (AFB) was found to be 30.71% and that of CBNAAT was 38.57%. Sensitivity of CBNAAT for sputum smear–positive and sputum smear–negative TB was 100 and 11.3%, respectively. Sensitivity of ZN smear for AFB of EPTB sample was 48.1% and that of CBNAAT was 59.25%. In both PTB and EPTB, CBNAAT showed an increase in diagnosis of microbiologically confirmed PTB cases by 7.8 and 11.1%, respectively, over and above the cases diagnosed by ZN smear microscopy. Rifampicin resistance was detected in five patients. We conclude that CBNAAT is a rapid test with better sensitivity in diagnosis of PTB and EPTB in PLHIV, compared with ZN smear microscopy. It detects rifampicin resistance for multidrug-resistant TB and helps in early treatment intervention.

Obstetric Violence

Background: Obstetric violence is a worldwide public health problem, which seems greater in Spain. As no studies were found that identify the most representative healthcare professionals, times, and areas involved in obstetric violence, the objective of this work was to study at what time of maternity, with which professionals, and in what areas women identified obstetric violence. Methods: This descriptive, retrospective, and cross-sectional study was performed from January 2018 to June 2019. The main variables were the area (hospital, primary care, both), the time (pregnancy, birth, puerperium), and the professionals attending to women. Results: Our sample comprised 17,541 participants. The area identified with the most obstetric violence for the different studied variables was hospitals. Women identified more obstetric violence at time of birth. Findings such as lack of information and informed consent (74.2%), and criticism of infantile behavior and treatment (87.6%), stood out. The main identified healthcare professionals were midwives and gynecologists, and “other” professionals repeatedly appeared. Conclusions: Having identified the professionals, times, and areas of most obstetric violence in Spain, it seems necessary to reflect on not only the Spanish National Health System’s structure and management but also on healthcare professionals’ training.
