Helicobacter pylori -bacteria of genus Helicobacter-is present in human gastric mucosa and plays an ethiological role in acid-peptic conditions, both benign and malignant, such as gastritis, gastric and duodenal peptic ulcers, gastric adenocarcinoma and non- Hodgkin lymphoma of lymphoid tissue presentin gastric mucosa (MALT).Since early diagnosis and treatment are relevant, interest have been placed on studying risk factors, contagiousness and prevalence, facts related to public health. New research has shown H. heilmanni, felis and rappini in pet’s gastric mucosa, with an eventual zoonotic component for a possible infection of human gastric mucosa.

Lara Osorio, Andrés Mauricio | 2009

Las dioxinas son los contaminantes ambientales de mayor trascendencia mundialmente, por los efectos que producen en la salud animal y humana. Son contaminantes de síntesis no intencional, lo que significa que se forman espontáneamente por reacciones químicas y en procesos industriales como la combustión, incineración, fundición de metales, en la fabricación de compuestos clorados. Dentro de las características de mayor relevancia toxicológica de estas sustancias, están su ubicuidad y persistencia en los componentes bióticos y abióticos, su alta capacidad de bioacumulación, explicada por la liposolubilidad de la molécula. Los efectos adversos producidos y demostrados incluyen, alteraciones de la reproducción, malformaciones, carcinogenicidad, inmunotoxicidad, anorexia y alteraciones hepaticas, muchos de ellos, comunes en animales y humanos. El conocimiento profundo de las características fisicoquímicas, de la toxicocinética, toxicodinamia y de todos los efectos que producen las dioxinas en los animales y humanos, permitirá desarrollar medidas correctivas aplicables a cada país, para disminuir el riesgo en la población humana y animal. Este trabajo hizo una revisión bibliográfica con objetividad y remitidos únicamente a información científica publicada por entidades serias que respalden las afirmaciones realizadas.

Estimates, trends, and drivers of the global burden of type 2 diabetes attributable to PM2·5 air pollution, 1990–2019: an analysis of data from the Global Burden of Disease Study 2019

Background Experimental and epidemiological studies indicate an association between exposure to particulate matter (PM) air pollution and increased risk of type 2 diabetes. In view of the high and increasing prevalence of diabetes, we aimed to quantify the burden of type 2 diabetes attributable to PM2·5 originating from ambient and household air pollution. Methods We systematically compiled all relevant cohort and case-control studies assessing the effect of exposure to household and ambient fine particulate matter (PM2·5) air pollution on type 2 diabetes incidence and mortality. We derived an exposure–response curve from the extracted relative risk estimates using the MR-BRT (meta-regression— Bayesian, regularised, trimmed) tool. The estimated curve was linked to ambient and household PM2·5 exposures from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019, and estimates of the attributable burden (population attributable fractions and rates per 100000 population of deaths and disability-adjusted life-years) for 204 countries from 1990 to 2019 were calculated. We also assessed the role of changes in exposure, population size, age, and type 2 diabetes incidence in the observed trend in PM2·5-attributable type 2 diabetes burden. All estimates are presented with 95% uncertainty intervals. Findings In 2019, approximately a fifth of the global burden of type 2 diabetes was attributable to PM2·5 exposure, with an estimated 3·78 (95% uncertainty interval 2·68–4·83) deaths per 100 000 population and 167 (117–223) disabilityadjusted life-years (DALYs) per 100000 population. Approximately 13·4% (9·49–17·5) of deaths and 13·6% (9·73–17·9) of DALYs due to type 2 diabetes were contributed by ambient PM2·5, and 6·50% (4·22–9·53) of deaths and 5·92% (3·81–8·64) of DALYs by household air pollution. High burdens, in terms of numbers as well as rates, were estimated in Asia, sub-Saharan Africa, and South America. Since 1990, the attributable burden has increased by 50%, driven largely by population growth and ageing. Globally, the impact of reductions in household air pollution was largely offset by increased ambient PM2·5. Interpretation Air pollution is a major risk factor for diabetes. We estimated that about a fifth of the global burden of type 2 diabetes is attributable PM2·5 pollution. Air pollution mitigation therefore might have an essential role in reducing the global disease burden resulting from type 2 diabetes

Galvis Marín, Juan C. | 2016-07

Las zoonosis son enfermedades que se transmiten de forma natural entre los animales vertebrados y el hombre. Existe un gran número de enfermedades bacterianas, virales y parasitarias, que son transmitidas de los animales a los humanos, mientras que pocas micosis son consideradas, actualmente, como zoonosis. Las micosis zoonóticas son más frecuentes en individuos inmunocomprometidos, incluyendo pacientes hospitalizados, en los cuales, Malassezia pachydermatis, una levadura zoofílica, aparece como un microorganismo importante, en la etiología de micosis nosocomiales. En esta revisión, se mencionan las publicaciones que han reportado la presencia de M. pachydermatis en humanos, a través del tiempo, con especial énfasis, en infecciones sistémicas en población de riesgo, a partir de caninos y personal de la salud, colonizados por esta levadura. Asimismo, se recopilan estudios en los que se han aislado en animales, especies antropofílicas del género Malassezia, para contribuir al conocimiento de la ecología y posible mecanismo de transmisión zoonótica, de este microorganismo.

Situational experience around the world: A replication and extension in 62 countries

Lee, Daniel I. | 2020

Objective: The current study seeks to replicate and extend principal findings reported in The World at 7:00, a project that examined the psychological experience of situations in 20 countries. Method: Data were collected from participants in 62 countries (N = 15,318), recruited from universities by local collaborators to complete the study via a custom-built website using 42 languages. Results: Several findings of the previous study were replicated. The average reported situational experience around the world was mildly positive. The same countries tended to be most alike in reported situational experience (r =.60) across the two studies, among the countries included in both. As in the previous study, the homogeneity of reported situational experience was significantly greater within than between countries, although the difference was small. The previously reported exploratory finding that negative aspects of situations varied more across countries than positive aspects did not replicate. Correlations between aspects of reported situational experience and country-level average value scores, personality, and demographic variables were largely similar between the two studies. Conclusion: The findings underscore the importance of cross-cultural situational research and the need to replicate its results, and highlight the complex interplay of culture and situational experience
