Feridas por projétil de arma de Fogo na coluna vertebral no ABSTRACT Objective: To compare the measurement of the Cobb angle in printed radiographs and digitalized radiographs displayed with the "PixViewer" tool. Methods: Pre-operative radiographs of 23 patients were performed in printed films and using the software "PixViewer". The same evaluator, a spine surgeon, chose the proximal and distal end vertebrae at the limit of the main curve in printed radiographs without identifying patients, and measured the Cobb angle based on these parameters. The same parameters and measurements were performed in digitalized radiographs. The measurements were compared, as well as the choice of end vertebrae. Results: The average change in the Cobb angle between the methods was 1.48±1.73°. The intraclass correlation coefficient (ICC) was 0.99, demonstrating excellent reproducibility. Conclusion: The Cobb method can be used to evaluate scoliosis through the "PixViewer" tool with the same reliability of the classic method on printed radiographs

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Identificación de arbustos y material vegetativo que consumen cabras en el cuarto distrito de Tamaulipas

En Tamaulipas la región del altiplano comprende los municipios de Tula, Jaumave, Palmillas y Miquihuana se desarrolla una parte de la caprinocultura de la entidad. En esta región árida dominan las arbustivas y las plantas espinosas como alimento forrajero. El objetivo del estudio fue identificar los materiales vegetativos disponibles en esta región y preferidos por las cabras. Por lo que se observaron y monitorearon las cabras registrando las plantas preferidas, consumidas y frecuencias (>20) durante un año en las cuatro localidades. Se utilizaron cuatro caprinos fistulados esofágicamente y adiestrados en el manejo y seguimiento de sus hábitos de pastoreo, ramoneo y tiempos de descanso que acompañaban a diferentes rebaños. La información generada se analizó en un diseño completamente al azar. Se contabilizaron en total 26 materiales variando en cada municipio (P<0.05). En Tula las cabras consumieron: Myrtillocactus geometrizans, Prosopis glandulosa, Euphorbia lactea, Ceratnia siliqua, Arecaceae palmae, Hechtia glomerata, Larrea tridentata, Cirsium medium, Cestrum fasciculatum, Acacia berlandieri y Koeberlinia spinosa (11). En Miquihuana fueron: Acacia berlandieri. Havardia pallens, Acacia farnesiana, Bursera laxiflora, Eysenhardtia polystachya, Celtis pallida, Avena sativa, Lysiloma candida, Psorothamnus spinosus y Prosopis Glandulosa (10). En Jaumave se registraron: Thymophylla setifolia, Jatropha dioica, Cynoglossum creticum, Eryhrina americana, Euphorbia antisyphilitica, Euphorbia antisyphilitica, Pistacia mexicana, Monnina xalapensis y Dasylirion wheeleri (9). En Bustamante se identificaron: Larrea tridentata, Hechtia glomerata, Prosopis glandulosa, Koeberlinia spinosa, Cirsium medium y Euphorbia antisyphilitica (6). Se concluye que se pueden establecer algunas estrategias de alimentación como la resiembra de estos materiales en esta región

Burnout Syndrome in a Military Tertiary Hospital Staff during the COVID-19 Contingency

(1) Background: Burnout syndrome (BOS) is defined as a psychological state of physical and mental fatigue associated with work. The COVID-19 pandemic greatly impacted the physical and mental wellbeing of health professionals. The objective of this work was to determine the impact on personnel, monitoring the frequency of BOS throughout the pandemic. (2) Methods: The Maslach Burnout Inventory (MBI) was self-applied in four periods of the pandemic according to sociodemographic and employment characteristics. In this study, all hospital personnel were included; the association of BOS with sex, age, type of participant (civilian or military), military rank and profession was analyzed. (3) Results: The frequency of BOS was 2.4% (start of the pandemic), 7.9% (peak of the first wave), 3.7% (end of the first wave) and 3.6% (peak of the third wave). Emotional exhaustion (EE) was the most affected factor, and the groups most affected were men under 30 years of age, civilians, chiefs and doctors, especially undergraduate medical doctors and specialty resident doctors, and nursing personnel were less affected. (4) Conclusions: The low BOS levels show that the containment measures and military training implemented by the hospital authorities were effective, although the chief personnel were more affected in the first wave. It is probable that this combination allowed the containment of BOS, which was not observed in civilians
