Worldwide prevalence of small ruminant lentiviruses in sheep: A systematic review and meta-analysis
Small Ruminant Lentiviruses (SRLV) are highly prevalent retroviruses with significant genetic diversity and antigenic heterogeneity that cause a progressive wasting disease of sheep called Maedi-visna. This work provides a systematic review and meta-analysis of the last 40 years (1981–2020) of scientific publications on SRLV individual and flock prevalence. Fifty-eight publications and 314 studies were included. Most articles used a single diagnostic test to estimate prevalence (77.6%), whereas articles using three or more tests were scarce (6.9%). Serological tests are more frequently used than direct methods and ELISA has progressively replaced AGID over the last decades. SRLV infection in sheep is widespread across the world, with Europe showing the highest individual prevalence (40.9%) and being the geographical area in which most studies have been performed. Africa, Asia, and North America show values between 16.7% to 21.8% at the individual level. South and Central America show the lowest individual SRLV prevalence (1.7%). There was a strong positive correlation between individual and flock prevalence (¿ = 0.728; p = 0.001). Despite the global importance of small ruminants, the coverage of knowledge on SRLV prevalence is patchy and inconsistent. There is a lack of a gold standard method and a defined sampling strategy among countries and continents
Odd- and Branched-Chain Fatty Acids in Lamb Meat as Potential Indicators of Fattening Diet Characteristics
There is a growing interest of researchers in meat authentication in terms of geographical and dietary background of animals, and several analytical methods have been proposed for the purpose of investigating this. We hypothesized that the odd- and branched-chain fatty acid (OBCFA) profile in intramuscular fat (IMF) might suffice to distinguish lamb meat entering the food chain supply on the basis of the type of diet fed to lambs during the fattening period. A total of 30 individual OBCFA profiles, quantified by gas chromatography, of IMF of Manchego lambs were used. During the fattening period (42 days), the lambs were fed three diets differing in concentrate composition: (i) Control, concentrate typical of commercial fattening rations, rich in starch and based on cereals and soybean meal; (ii) Camelina, similar to Control but replacing 50% of the soybean meal with camelina meal; and (iii) Fibrous, concentrate rich in neutral detergent fiber (NDF), based on fibrous by-products and not including cereals nor soybean meal. The OBCFA were grouped into three classes (linear odd, iso and anteiso fatty acids) and were then submitted to a linear discriminant analysis, using the feeding treatments as grouping variable and the OBCFA class contents in IMF as quantitative variables. The results suggested that a high NDF to starch ratio of the concentrate, being the lowest for Control (CON) treatment and the highest for Fibrous (FIB) treatment, would be negatively related to the odd/anteiso ratio and positively related to the iso/(anteiso+odd) FA ratio in IMF. Determination of OBCFA profile in lamb meat would be useful to monitor the feeding regime (starch- or NDF-rich) of lambs entering the food chain supply
Sex Differences in COVID-19 Hospitalization and Hospital Mortality among Patients with COPD in Spain: A Retrospective Cohort Study
We aimed to assess the effect of COPD in the incidence of hospital admissions for COVID-19 and on the in-hospital mortality (IHM) according to sex. (2) Methods: We used national hospital discharge data to select persons aged ≥40 years admitted to a hospital with a diagnosis of COVID-19 in 2020 in Spain. (3) Results: The study population included 218,301 patients. Age-adjusted incidence rates of COVID-19 hospitalizations for men with and without COPD were 10.66 and 9.27 per 1000 persons, respectively (IRR 1.14; 95% CI 1.08–1.20; p < 0.001). The IHM was higher in men than in women regardless of the history of COPD. The COPD was associated with higher IHM among women (OR 1.09; 95% CI 1.01–1.22) but not among men. The COPD men had a 25% higher risk of dying in the hospital with COVID-19 than women with COPD (OR 1.25, 95% CI 1.1–1.42). (4) Conclusions: Sex differences seem to exist in the effect of COPD among patients suffering COVID-19. The history of COPD increased the risk of hospitalization among men but not among women, and COPD was only identified as a risk factor for IHM among women. In any case, we observed that COPD men had a higher mortality than COPD women. Understanding the mechanisms underlying these sex differences could help predict the patient outcomes and inform clinical decision making to facilitate early treatment and disposition decisions.Fac. de Enfermería, Fisioterapia y PodologíaTRUEComunidad de MadridUniversidad Complutense de Madridpu
Sex Differences in the Effects of COPD on Incidence and Outcomes of Patients Hospitalized with ST and Non-ST Elevation Myocardial Infarction: A Population-Based Matched-Pair Analysis in Spain (2016–2018)
We aimed to compare the incidence, clinical characteristics, and outcomes of patients admitted with myocardial infarction (MI), whether ST elevation MI (STEMI) or non-ST elevation MI (NSTEMI), according to the presence of chronic obstructive pulmonary disease (COPD), and to identify variables associated with in-hospital mortality (IHM). We selected all patients with MI (aged ≥40 years) included in the Spanish National Hospital Discharge Database (2016–2018). We matched each patient suffering COPD with a non-COPD patient with identical age, sex, type of MI, and year of hospitalization. We identified 109,759 men and 44,589 women with MI. The MI incidence was higher in COPD patients (incident rate ratio (IRR) 1.32; 95% confidence interval (CI) 1.29–1.35). Men with COPD had higher incidence of STEMI and NSTEMI than women with COPD. After matching, COPD men had a higher IHM than non-COPD men, but no differences were found among women. The probability of dying was higher among COPD men with STEMI in comparison with NSTEMI (odds ratio (OR) 2.33; 95% CI 1.96–2.77), with this risk being higher among COPD women (OR 2.63; 95% CI 1.75–3.95). Suffering COPD increased the IHM after an MI in men (OR 1.14; 95% CI 1.03–1.27), but no differences were found in women. COPD women had a higher IHM than men (OR 1.19; 95% CI 1.01–1.39). We conclude that MI incidence was higher in COPD patients. IHM was higher in COPD men than in those without COPD, but no differences were found among women. Among COPD patients, STEMI was more lethal than NSTEMI. Suffering COPD increased the IHM after MI among men. Women with COPD had a significantly higher probability of dying in the hospital than COPD men
El uso de rúbricas para una evaluación justa y objetiva en asignaturas prácticas de enseñanzas técnicas y su repercusión en el aprendizaje
[ES] En el nuevo marco de Enseñanza Superior Europeo la evaluación ha pasado de ser una
herramienta de control del alumno a una parte más del proceso de aprendizaje. De hecho, una
buena evaluación debe estar alineada con los objetivos de la asignatura y la metodología
aplicada. En este contexto, el uso de herramientas de evaluación, como la rúbrica, tiene un
gran potencial.
En este trabajo se valora la utilidad del uso de rúbricas en asignaturas técnicas eminentemente
prácticas. Se han tenido en consideración asignaturas de tres áreas de conocimiento dispares,
como son la Ingeniería Informática, la Ingeniería Industrial y la Ingeniería de la Edificación.
Todas ellas tienen en común que son asignaturas eminentemente prácticas y en las que los
alumnos tienen que realizar entregas frecuentes de productos. En esta comunicación se
plantea la idoneidad del uso de rúbricas en este tipo de asignaturas para la evaluación de las
entregas de los alumnos. El análisis se ha realizado tanto desde el punto de vista del profesor
como el de los alumnos. Los profesores aportan evidencias cuantitativas de la mejora
observada en las calificaciones de los alumnos y sus impresiones personales sobre la utilidad
de la herramienta. Por otra parte, se han recogido evidencias en forma de encuesta de los
alumnos, en las que también valoran de forma muy positiva el uso de rúbricas, sobre todo a la
hora de planificar su trabajo de cara a la entrega.Alfaro Cid, E.; Andrés Ferrer, J.; Montalva Subirats, JM.; Pérez De Los Cobos Cassinello, M. (2013).

Effect of COPD on the Hospital Outcomes and Mortality among Hemorrhagic Stroke Patients. Sex Differences in a Population-Based Study
(1) Background: It is not well known whether there is an association between COPD and hemorrhagic stroke (HS). We aim to analyze the incidence, clinical characteristics, procedures, and outcomes of HS in patients with and without COPD and to assess sex differences. Secondly, to identify factors associated with in-hospital mortality (IHM). (2) Methods: Patients aged ≥40 years hospitalized with HS included in the Spanish National Hospital Discharge Database (2016–2018) were analyzed. Propensity score matching (PSM) was used to compare patients according to sex and COPD status. (3) Results: We included 55,615 patients (44.29% women). Among men with COPD the HS adjusted incidence was higher (IRR 1.31; 95% CI 1.24–1.57) than among non-COPD men. COPD men had higher adjusted incidence of HS than COPD women (IRR 1.87; 95% CI 1.85–1.89). After matching, COPD men had a higher IHM (29.96% vs. 27.46%; p = 0.032) than non-COPD men. Decompressive craniectomy was more frequently conducted among COPD men than COPD women (6.74% vs. 4.54%; p = 0.014). IHM increased with age and atrial fibrillation, while decompressive craniectomy reduced IHM. (4) Conclusions: COPD men had higher incidence and IHM of HS than men without COPD. COPD men had higher incidence of HS than COPD women. Decompressive craniectomy was more frequently conducted in COPD men than COPD women and this procedure was associated to better survival
Consumo de opioides: análisis de su disponibilidad y acceso en Colombia
162 páginas: ilustracionesEste libro pretende analizar la disponibilidad y el acceso a los medicamentos opioides en Colombia; entender el problema desde una perspectiva multidimensional, con énfasis territorial, e integrar a los diferentes actores que participan en los procesos requeridos para estos analgésicos.
El propósito es identificar las barreras de disponibilidad y acceso a medicamentos opioides, a fin de disminuir las “diferencias evitables” entre grupos de personas por razones sociales, económicas, geográficas o demográficas, para que todos tengan oportunidades justas para alcanzar su máximo potencial en salud y el alivio del sufrimiento.
También, busca ofrecer a los tomadores de decisiones, formuladores de políticas públicas, agencias gubernamentales, no gubernamentales y academia, un diagnóstico sobre lo que ocurre con el consumo de opioides y, por tanto, con el goce efectivo del derecho al alivio del dolor y el sufrimiento innecesario en Colombia.1.

Prevalence and Determinants of Mental Health among COPD Patients in a Population-Based Sample in Spain
(1) Background: To assess the prevalence of mental disorders (depression and anxiety), psychological distress, and psychiatric medications consumption among persons suffering from COPD; to compare this prevalence with non-COPD controls and to identify which variables are associated with worse mental health. (2) Methods: This is an epidemiological case-control study. The data were obtained from the Spanish National Health Survey 2017. Subjects were classified as COPD if they reported suffering from COPD and the diagnosis of this condition had been confirmed by a physician. For each case, we selected a non-COPD control matched by sex, age, and province of residence. Conditional logistic regression was used for multivariable analysis. (3) Results: The prevalence of mental disorders (33.9% vs. 17.1%; p < 0.001), psychological distress (35.4% vs. 18.2%; p < 0.001), and psychiatric medications consumption (34.1% vs. 21.9%; p < 0.001) was higher among COPD cases compared with non-COPD controls. After controlling for possible confounding variables, such as comorbid conditions and lifestyles, using multivariable regression, the probability of reporting mental disorders (OR 1.41; 95% CI 1.10–1.82).), psychological distress (OR 1.48; 95% CI 1.12–1.91), and psychiatric medications consumption (OR 1.38 95% CI 1.11–1.71) remained associated with COPD. Among COPD cases, being a woman, poor self-perceived health, more use of health services, and active smoking increased the probability of suffering from mental disorders, psychological distress, and psychiatric medication use. Stroke and chronic pain were the comorbidities more strongly associated with these mental health variables. (4) Conclusions: COPD patients have worse mental health and higher psychological distress and consume more psychiatric medications than non-COPD matched controls. Variables associated with poorer mental health included being a woman, poor self-perceived health, use of health services, and active smoking
