RESUMEN
SUMMARY: In the sports field, sports are usually classified according to the predominance of the energy system used during the competition; sports like Crossfit and ultra-marathon could be totally opposite due to the needs of athletes to achieve good places. Due to the above, the objective was established to compare the dermatoglyphic profiles of CrossFit and Ultra-marathon athletes according to the predisposition of the energy systems, aerobic and anaerobic, used in the competitions. Cross-sectional descriptive study, where the dermatoglyphic profile of 21 athletes of national presence (10 crossfit and 11 ultra-marathon runners) was determined, through the Computerized Dermatoglyphic System, brand Salus Dermatoglifia, according to the Cummins and Midlo protocol, which consists of taking the fingerprints of the 10 fingers of the hands. The fingerprint designs of the human being (arch, loop and whorl) and the elements contained in them (nucleus and delta) were analyzed, differences were established through the Analysis of Variance test in the SPSS V.25 statistical package. The results show significant differences between the average scores of the line count of both disciplines (108 and 165), being higher in ultra-marathon runners, associated with greater aerobic resistance. Another significant and relevant finding was the presence of arch-type fingerprints only in CrossFit athletes associated, along with low line count, with strength and power. It is concluded that Crossfit and Ultra-marathon athletes have dissimilar natural physical characteristics, which is why they participate and excel in different sports where they have enhanced their natural physical abilities through training.
En el ámbito deportivo, los deportes suelen clasificarse según el predominio del sistema energético utilizado durante la competición; Deportes como el Crossfit y la ultramaratón podrían ser totalmente opuestos debido a las necesidades de los deportistas de conseguir buenos lugares. Debido a lo anterior, se estableció como objetivo comparar los perfiles dermatoglíficos de atletas de CrossFit y Ultramaratón según la predisposición de los sistemas energéticos, aeróbico y anaeróbico, utilizados en las competencias. Estudio descriptivo transversal, donde se determinó el perfil dermatoglífico de 21 deportistas de presencia nacional (10 crossfit y 11 ultramaratonistas), a través del Sistema Dermatoglífico Computarizado, marca Salus Dermatoglifia, según el protocolo Cummins y Midlo, el cual consta de tomando las huellas dactilares de los 10 dedos de las manos. Se analizaron los diseños dactilares del ser humano (arco, asa y verticilo) y los elementos contenidos en ellos (núcleo y delta), se establecieron diferencias mediante la prueba de Análisis de Varianza en el paquete estadístico SPSS V.25. Los resultados muestran diferencias significativas entre las puntuaciones medias del recuento de líneas de ambas disciplinas (108 y 165), siendo superiores en los corredores de ultramaratón, asociado a una mayor resistencia aeróbica. Otro hallazgo significativo y relevante fue la presencia de huellas dactilares tipo arco sólo en atletas de CrossFit asociadas, junto con un bajo número de líneas, con fuerza y potencia. Se concluye que los atletas de Crossfit y Ultramaratón tienen características físicas naturales disímiles, por lo que participan y destacan en diferentes deportes donde han potenciado sus capacidades físicas naturales a través del entrenamiento.

Little literature exists about critically ill patients with coronavirus disease 2019 (COVID-19) from Latin America. Here, we aimed to describe the clinical characteristics and mortality risk factors in mechanically ventilated COVID-19 patients from Mexico. For this purpose, we recruited 67 consecutive mechanically ventilated COVID-19 patients which were grouped according to their clinical outcome (survival vs. death). Clinical risk factors for mortality were identified by machine-learning and logistic regression models. The median age of participants was 42 years and 65% were men. The most common comorbidity observed was obesity (49.2%). Fever was the most frequent symptom of illness (88%), followed by dyspnea (84%). Multilobe ground-glass opacities were observed in 76% of patients by thoracic computed tomography (CT) scan. Fifty-two percent of study participants were ventilated in prone position, and 59% required cardiovascular support with norepinephrine. Furthermore, 49% of participants were coinfected with a second pathogen. Two-thirds of COVID-19 patients developed acute kidney injury (AKIN). The mortality of our cohort was 44.7%. AKIN, uric acid, lactate dehydrogenase (LDH), and a longitudinal increase in the ventilatory ratio were associated with mortality. Baseline PaO2/FiO2 values and a longitudinal recovery of lymphocytes were protective factors against mortality. Our study provides reference data about the clinical phenotype and risk factors for mortality in mechanically ventilated Mexican patients with COVID-19.
RESUMEN
Background: Cervicocranial arterial dissection (CIAD) is an important cause of stroke. Aim: To describe the clinical and imaging characteristics of patients with CIAD. Material and Methods: An anonymous registry was made including all patients admitted to a private hospital with a diagnosis of CIAD. Patients were subdivided as having an anterior or posterior circulation dissection (ACD or PCD, respectively). Results: Fifty-seven patients aged 40 ± 8 years (60% women) were included in the study, 39 with PCD and 18 with ACD. Cervical pain was the most common symptom. CIAD was diagnosed with no clinical or imaging signs of stroke in 49% of patients. Fifty one percent of patients had focal neurological deficits and 72% had a NIH stroke score below five. No significant differences between patients with ACD or PCD were found. Fifty patients received antiplatelet therapy (simple or dual), seven patients were anticoagulated and 13 were subjected to stenting due to progression of stenosis with hemodynamic involvement or bilateral dissection with scarce collaterals. The lesion was located in V3 segment in 27 patients and cervical segment of the internal carotid in 16 cases. A favorable Modified Rankin Scale (0-2) was achieved in 85.9%, with a trend towards achieving better functional prognosis in PCD. Conclusions: Due to the greater availability of non-invasive imaging methods, 50% of these patients with CIAD did not have a stroke. Thus, an earlier and more timely management is feasible.

Background: Acute ischemic stroke (AIS) is one of the leading causes of death in Chile. Intravenous thrombolysis (IVT) is an effective treatment. Geographical barriers and lack of specialists limit its application. Telemedicine can overcome some of these pitfalls. Aim: To describe the implementation and results of AIS treatment by telemedicine at the TeleStroke Unit (TeleACV) of the Southern Metropolitan Health Service, connected with seven hospitals in Chile. Material and Methods: Descriptive analysis of a prospective tele-thrombolysis data-base that covers from 2016 to 2018, with an emphasis in the last year. Results: During the analyzed period, seven remote telemedicine centers were activated as far as 830 kilometers on a continental level from the reference center and up to 3,700 kilometers on an island level. There were 1,024 telemedicine consultations, 144 (14%) of them resulted in an IVT treatment. During 2018, 597 tele-consultations were made, thrombolysis was done in 115 (19%) patients aged 66+-13 years; 54 (46.6%) being female. The median admission National Institute of Health Stroke Scale was 8 (interquartile range (IQR) 5-14). The median door-to-needle time was 56.5 (IQR 44.8-73.3) minutes; 60% of patients were treated within 60 minutes. Eight patients (7%) were referred for a subsequent mechanical thrombectomy to a center of greater complexity. Symptomatic intra-cranial hemorrhages occurred in four treated patients (4%). One patient had a systemic bleeding. Conclusions: The Telestroke Unit achieved a high rate of IVT and good door-to-needle times. This may help to overcome some of the geographic barriers and the specialist availability gap in our country.
