[Housing conditions and care system as determinants of the intra-family transmission of covid-19: case-control study in Castilla y León.] / Condiciones de vivienda y sistema de cuidados como determinantes de la transmisión intrafamiliar de covid-19: estudio de casos y controles en Castilla y León.

OBJECTIVE: The health of people can be affected by the habitability of their home conditions and the dynamics of family care in home. The aim of this work was to calculate the intrafamily secondary attack rate (TAS) in Castilla y León and its relationship with characteristics of the living places and the cohabitants. METHODS: Multicenter case-control study in Covid-19 patients through telephone interview. Case: person in whose house there was more than one Covid-19 positive during the study period. TAS was calculated and univariate and multivariate analyzes were performed. RESULTS: TAS calculated was 29.8%. The risk was higher for each increase in one unit in the number of co-inhabitants (OR=3.1); if stays were shared (OR=4.43); if ventilating the temperature worsened (OR=3.8) and if there were dependents at home (OR=3.2). CONCLUSIONS: The search for housing vulnerable to Covid-19 accompanied by fast, close measures and interventions on the social determinants of health can reduce the TAS of the disease.

OBJETIVO: La salud de las personas puede afectarse por las condiciones de habitabilidad y la dinámica de cuidados familiares en las viviendas. El objetivo de este trabajo fue calcular la tasa de ataque secundario intrafamiliar (TAS) en Castilla y León y su relación con características de las viviendas y sus cohabitantes. METODOS: Estudio de casos y controles multicéntrico en pacientes con Covid-19 a través de entrevista telefónica. Caso: persona en cuyo domicilio constó más de una persona Covid-19 positivo durante el periodo de estudio. Se calculó la TAS y se realizó análisis uni y multivariable. RESULTADOS: La TAS calculada fue de 29,8%. El riesgo fue mayor por cada aumento en una unidad en el número de convivientes (OR=3,1); si se compartían estancias (OR=4,43); si ventilar empeoraba la temperatura (OR=3,8) y si había dependientes (OR=3,2). CONCLUSIONES: La búsqueda de viviendas vulnerables a Covid-19 acompañada de medidas rápidas, cercanas e intervenciones sobre los determinantes sociales de la salud pueden reducir la TAS.

Nosocomial Vs. Community-Acquired Infective Endocarditis in Spain: Location, Trends, Clinical Presentation, Etiology, and Survival in the 21st Century.

Major changes have occurred in the epidemiology and etiology of infective endocarditis (IE). Nevertheless, the differences between nosocomial infective endocarditis (NIE) and community-acquired infective endocarditis (CIE) have not been addressed in a population-based study. We conducted a retrospective, nationwide, temporal trend study from 1997 to 2014 analyzing the epidemiology, clinical, geographical, meteorological characteristics of patients diagnosed with IE in Spain, to distinguish NIE from CIE. Among 25,952 patients with IE (62.2 ± 18·6 years; 65.9% men), 45.9% had NIE. The incidence of IE increased from 2.83 to 3.73 due to the NIE incidence increment with a decline in CIE. Patients with NIE were older (63.8 years vs. 60.8 years, p < 0·001), presented a higher Charlson index (1.22 vs. 1.03, p < 0.001), a greater history of implanted cardiac devices (8.7% vs. 4.6%, p < 0.001), and higher mortality (31.5% vs. 21.7%, p < 0.001). The most frequent microorganism for both NIE and CIE was Staphylococcus (p < 0.001), and the North reported a higher incidence (p < 0.001). Risk factors of mortality for NIE were age, Charlson index, hemodialysis, shock, heart failure, and stroke. Risk factors for CIE included female sex, renal disease, and cardiac-device carriers. The etiology of IE shifted from community origins to mostly nosocomial-associated infections. Higher morbidity, mortality, and poorer outcomes are associated with NIE.

[Validation of a questionnaire on attitudes and practice of physical activity and other healthy habits through the Delphi method]. / Validación de un cuestionario sobre actitudes y práctica de actividad física y otros hábitos saludables mediante el método Delphi.

OBJECTIVE: Physical inactivity and sedentary lifestyle are an emerging individual, familiar and social public health problem. The aim of this work was to validate a new questionnaire to know the attitude towards physical activity and other habits in adolescents. METHODS: The Delphi method was used. It was developed in three phases: an initial phase of selection of the panel of experts, an exploratory phase in two rounds of voting using a Likert scale of 1 to 5, and statistical and qualitative analysis of the experts' contributions. The criteria for the choice of items were: average >3.5 and factor V of Aiken ≥0.7. Reliability was assessed with the Cronbach alpha coefficient. A pilot test was carried out to assess the understanding of the instrument. RESULTS: 21 experts agreed to participate. Their participation was 100% in the first round and 95.2% in the second one. Seven items did not meet the criteria. The final questionnaire included 93 questions and 11 dimensions: data of the student, father, mother, physical activity in the educational center, transportation, free time, psychosocial aspects of physical activity, attitude towards physical activity, food, other habits and health perception. A Cronbach's alpha of 0.974 was obtained. CONCLUSIONS: The results support the reliability and validity of the questionnaire. The Delphi method proved to be a useful technique for the proposed objective.

Brote de tuberculosis resistente a isoniacida en una comunidad de inmigrantes en España / Outbreak of isoniazid-resistant tuberculosis in an immigrant community in Spain

Introducción: La tuberculosis (TB) continúa siendo un importante problema de salud pública. En 2013 se declararon 9 millones de casos nuevos de TB activa a nivel mundial, siendo la proporción de nuevos casos de TB multirresistente del 3,5%. Método: Se realizó un estudio de contactos de un caso de TB pulmonar en una paciente de nacionalidad boliviana. Las pruebas diagnósticas se realizaron según los protocolos establecidos a nivel nacional y local. Resultados: Se detectaron 5 casos a partir del caso índice y se constató la existencia de un brote de TB en una comunidad inmigrante. El resultado del genotipado y del antibiograma ampliado de las muestras de esputo fue crecimiento de Mycobacterium tuberculosis (KatG-msp no mutado/inhA C-T 5RBS) resistente a isoniacida. Se realizó la búsqueda activa de convivientes y contactos con un censo total de 39 personas. La incidencia de infección latente fue de 71,43%. Discusión: El estudio de este brote como otros en la literatura constata la importancia de la búsqueda activa de la localización de contactos y su estudio, de la investigación de laboratorio para lograr la mejora en la detección precoz de la TB. Un diagnóstico precoz del enfermo, el cumplimiento de un tratamiento adecuado y la vigilancia de la farmacorresistencia se consideran pilares fundamentales para la prevención y el control de la TB

Background: Tuberculosis (TB) remains a major public health problem. In 2013, 9 million new cases of active TB were estimated globally and the proportion of reported new cases with multi-drug resistance (MDR) was 3.5%. Methods: Contact tracing of a case of pulmonary tuberculosis was performed in a Bolivian patient. Diagnostic tests were performed according to national and local protocols. Results: An outbreak of tuberculosis in an immigrant community was detected, with 5 cases originating from one index case. Genotyping and drug susceptibility testing of the sputum samples determined Mycobacterium tuberculosis resistant to isoniazid (KatG-msp unmutated/inhA 5RBS CT). Active case finding revealed a total of 39 contacts with an incidence of latent infection of 71.43%. Conclusions: The present study confirms the importance of active case finding through contact tracing as well as rapid laboratory diagnosis to achieve improvements in early detection of TB. Early diagnosis of the patient, compliance with appropriate treatment protocols and monitoring of drug resistance are considered essential for the prevention and control of TB

Developing countries: health round-trip.

International travel can pose various risks to health, depending both on the health needs of the traveller and on the type of travel to be undertaken. Travellers intending to visit a destination in a developing country should consult a travel medicine clinic or medical practitioner before the journey. General precautions can greatly reduce the risk of exposure to infectious agents. Vaccination is a highly effective method of preventing certain infectious diseases. The aim of this study is to know the risks involved and the best way to prevent them.

Malaria in developing countries.

Malaria still poses a real threat to travellers, particularly in areas with high transmission rates such as sub-Saharan Africa, Papua New Guinea, and the South Pacific islands. Malaria causes an estimated 660,000 deaths each year from 219 million cases of illness. It is a preventable and curable disease. Malaria symptoms appear after a period of seven days or longer, and without treatment, the disease can lead to death. Mosquito bite prevention is the main way to reduce malaria transmission. Chemoprophylaxis recommendations depend on travelers' age, destination, type of travelling, or length of stay. Pregnant women, children, and immunosuppressed travelers are the most susceptible. There are currently no licensed vaccines against malaria. Results about a research vaccine candidate known as RTS,S/AS01 are expected in 2015.
