Electrocardiografía en equinos fina sangre de carrera

The Thoroughbreds horses are highly competitive athletes under great physical demands. To achieve a good performance they need a constant adaptation process of the cardiovascular system to exercise. Within the routine examination of this system, a substantial number of cardiovascular abnormalities can be detected (arrhythmias, murmurs, splitting of heart sounds, etc.), since these animals are competing successfully, it is logical to think that these correspond to the expression of the adaptation process of the cardiovascular system to exercise and not necessarily organically based pathology. Therefore, a very important and useful tool is the collection and interpretation of an electrocardiogram (recording of electrical activity of the heart). Age, training, competition, gender, among others, are variables that affect some of the electrocardiographic parameters. To complete a proper interpretation of the electrical activity generated by cardiac mass, it is necessary to obtain a vector analysis of the electrocardiogram.    Los Equinos Fina Sangre de Carrera son caballos de alta competencia que se encuentran sometidos a grandes exigencias físicas. Para que estos ejemplares obtengan buenos rendimientos es necesario que en ellos ocurra un proceso constante de adaptación al ejercicio. Un número considerable de anormalidades cardiovasculares (arritmias, soplos, desdoblamientos de tonos cardíacos, etc.), pueden ser detectadas al realizar un examen cardiovascular de rutina. Sin embargo, muchos de los ejemplares a los cuales se les detectan dichas alteraciones, se encuentran compitiendo con éxito, por lo que resulta lógico pensar, que estas anomalías corresponden a la expresión del proceso de adaptación cardiovascular al ejercicio y no necesariamente a una patología de base orgánica. Por lo tanto, una herramienta muy importante es el registro e interpretación de un electrocardiograma (registro de la actividad eléctrica del corazón). La edad, entrenamiento, competencia, género, entre otras, son variables que pueden afectar los parámetros electrocardiográficos. Para completar el estudio de la actividad eléctrica generada por la masa cardíaca, es necesario realizar un análisis vectorial a partir del electrocardiograma.  

Perceptions and experiences with eating disorder treatment in the first year of COVID-19: A longitudinal qualitative analysis

Objective: The COVID-19 pandemic created significant challenges in accessing and receiving treatment for individuals with eating disorders (EDs). The purpose of this study is to explore perceptions of and experiences with ED treatment during the first year of the pandemic among individuals with past and self-reported EDs in the United States. Methods: Online surveys were administered to adults (N = 510) with a past or current self-reported ED at 13 timepoints between April 2020 and May 2021. Using longitudinal qualitative analysis, 5651 free-text responses were examined to capture experiences with ED treatment and generate inferences of change over time. Results: We categorized results into four sequential, temporal quarters and identified patterns that explained participants' perceptions of facilitators, barriers, and experiences with ED treatment over time: Quarter 1. Treatment Disruption and Reorienting Recovery; Quarter 2. Accumulating COVID-19 Stress and Virtual Treatment Woes; Quarter 3. A Continuation of Inadequate Care; and Quarter 4. Ongoing Adaptation and Adjustment to Uncertainty. Participant experiences were marked by numerous barriers to accessing care, challenges adjusting to virtual treatment, unmet treatment needs, and beginning acceptance of telehealth. Discussion: Our findings present a timeline to help evaluate challenges related to navigating the switch to virtual care which created significant disruption to ED recovery. Participants spent much of the first year trying to adjust to unemployment, loss of insurance, and lack of access to in-person treatment. Future research should identify additional strategies to improve the receipt and experience of care for EDs. Public Significance: Our findings suggest that individuals with eating disorders were significantly challenged by accumulating COVID-19 stress, worsening symptomatology, and limited access to effective treatment during the first year of the pandemic. This knowledge can guide clinicians, treatment centers, and policy makers in addressing the behavioral health needs of individuals impacted by disordered eating amidst emergent public health crises

Evolution of the use of corticosteroids for the treatment of hospitalised COVID-19 patients in Spain between March and November 2020: SEMI-COVID national registry

Objectives: Since the results of the RECOVERY trial, WHO recommendations about the use of corticosteroids (CTs) in COVID-19 have changed. The aim of the study is to analyse the evolutive use of CTs in Spain during the pandemic to assess the potential influence of new recommendations. Material and methods: A retrospective, descriptive, and observational study was conducted on adults hospitalised due to COVID-19 in Spain who were included in the SEMI-COVID- 19 Registry from March to November 2020. Results: CTs were used in 6053 (36.21%) of the included patients. The patients were older (mean (SD)) (69.6 (14.6) vs. 66.0 (16.8) years; p < 0.001), with hypertension (57.0% vs. 47.7%; p < 0.001), obesity (26.4% vs. 19.3%; p < 0.0001), and multimorbidity prevalence (20.6% vs. 16.1%; p < 0.001). These patients had higher values (mean (95% CI)) of C-reactive protein (CRP) (86 (32.7-160) vs. 49.3 (16-109) mg/dL; p < 0.001), ferritin (791 (393-1534) vs. 470 (236- 996) µg/dL; p < 0.001), D dimer (750 (430-1400) vs. 617 (345-1180) µg/dL; p < 0.001), and lower Sp02/Fi02 (266 (91.1) vs. 301 (101); p < 0.001). Since June 2020, there was an increment in the use of CTs (March vs. September; p < 0.001). Overall, 20% did not receive steroids, and 40% received less than 200 mg accumulated prednisone equivalent dose (APED). Severe patients are treated with higher doses. The mortality benefit was observed in patients with oxygen saturation </=90%. Conclusions: Patients with greater comorbidity, severity, and inflammatory markers were those treated with CTs. In severe patients, there is a trend towards the use of higher doses. The mortality benefit was observed in patients with oxygen saturation </=90%

Abdômen agudo em equídeos no semiárido da região nordeste do Brasil

Foram revisados os casos de abdômen agudo de origem gastrintestinal em equídeos atendidos no Hospital Veterinário da Universidade Federal de Campina Grande, em Patos, Paraíba. No período de janeiro de 2001 a dezembro de 2010. Setenta (4,5%) do total de 1542 equídeos atendidos no período apresentaram quadro clínico de cólica, sendo 60 equinos, cinco muares e cinco asininos. A compactação de cólon maior foi a causa mais frequente de cólica, diagnosticada em 37,14% dos casos, seguida por compactação de cólon menor (10%) e corpo estranho de cólon menor (7,14%). Em quatro casos as cólicas foram causadas pela presença de fitobezoares no intestino grosso, sendo dois deles associados ao consumo de vagens de Prosopis juliflora. Em cinco casos foi observada a presença de corpos estranhos no cólon menor e em um caso os corposestranhos foram encontrados no cólon maior, sendo principalmente sacos plásticos. As lesões estrangulantes do intestino delgado foram observadas em quatro casos. Outras causas foram cólica espasmódica (dois casos por parasitose e dois por ingestão de resíduos domiciliares), sobrecarga gástrica (três casos) e deslocamento de cólon maior que foi diagnosticado em dois animais. Laceração de cólon menor, torção de ceco, compactação de ceco e timpanismo por consumo de Manihot esculenta foram diagnosticados em uma única ocasião. O principal fator de risco para o desenvolvimento de cólicas foi o consumo de Pennisetum purpureum, Brachiaria decumbens, Sorghum spp. ou Echinochloa polystachya picados manualmente ou em picotadeira ou triturados em forrageira (OR=4,03; P=0,007). Como resultado da baixa qualidade dos alimentos ingeridos, a frequência dos atendimentos de equídeos portadores de cólica foi significativamente maior no segundo semestre (época da seca na região estudada) (OR=2,61; P<0,01). Concluiu-se que a oferta de volumoso de baixa qualidade na seca contribui para a alta frequência de casos de cólica e que o manejo alimentar tem um papel importante na ocorrência da doença e, por isso, a sua melhoria pode influenciar positivamente na redução do número de casos de cólica em equídeos no semiárido nordestino

ϒ production in p–Pb collisions at √sNN=8.16 TeV

ϒ production in p–Pb interactions is studied at the centre-of-mass energy per nucleon–nucleon collision √sNN = 8.16 TeV with the ALICE detector at the CERN LHC. The measurement is performed reconstructing bottomonium resonances via their dimuon decay channel, in the centre-of-mass rapidity intervals 2.03 < ycms < 3.53 and −4.46 < ycms < −2.96, down to zero transverse momentum. In this work, results on the ϒ(1S) production cross section as a function of rapidity and transverse momentum are presented. The corresponding nuclear modification factor shows a suppression of the ϒ(1S) yields with respect to pp collisions, both at forward and backward rapidity. This suppression is stronger in the low transverse momentum region and shows no significant dependence on the centrality of the interactions. Furthermore, the ϒ(2S) nuclear modification factor is evaluated, suggesting a suppression similar to that of the ϒ(1S). A first measurement of the ϒ(3S) has also been performed. Finally, results are compared with previous ALICE measurements in p–Pb collisions at √sNN = 5.02 TeV and with theoretical calculations.publishedVersio
