Resumen : Abstract: Distiller grains (DG), which are the by-product from the bioethanol industry, represent
an interesting alternative as animal feedstock. To our knowledge, little information is available on
the inclusion of DG on the quality of meat from pasture-fed heifers. Thus, the aim of the present
study was to evaluate the effect of DG inclusion in pasture-based systems on the main meat quality
attributes of Charolais x Aberdeen Angus heifers. For this purpose, meat from heifers fed with a
pasture-based diet without supplementation (P) or with 0.75% of live weight DG supplementation
(PDG; DG plus dry-rolled corn, 50:50) or with 0.75% of live weight dry-rolled corn supplementation
(PRC) was evaluated. Physical (pH, WHC, color, texture), sensory and nutritional (fat content, fatty
acid, and amino acid profile) attributes were evaluated in beef samples. No effect of supplementation
was observed on meat pH or color (p > 0.05). Meat from PDG heifers showed higher values of WBSF
than meat from P heifers (p = 0.039). However, the overall tenderness evaluated by trained panelists
showed no differences due to supplementation (p > 0.05). Our results indicate that the inclusion of
DG as a partial corn-replacement supplementation for heifers under grazing represents a strategic
tool not only related to meat quality, but also as an alternative to reduce food–feed competition.2023-01-01T00:00:00ZEmerging concepts in heart failure management and treatment: focus on point-of-care ultrasound in cardiogenic shockRubén, MarielaMolinas, María SolPaladini, HugoKhalife, WissamBarbagelata, AlejandroPerrone, SergioKaplinsky, Edgardohttps://repositorio.uca.edu.ar/handle/123456789/166582023-07-05T05:01:13Z2023-01-01T00:00:00ZTítulo : Emerging concepts in heart failure management and treatment: focus on point-of-care ultrasound in cardiogenic shock

Resumen : Abstract: Point-of-care ultrasound (POCUS) plays a strategic role in the diagnostic and therapeutic evaluation of critically ill patients and, especially, in those who are haemodynamically unstable. In this context, POCUS allows a more precise identification of the cause, its differential diagnosis, the eventual coexistence with another entity and, finally, guiding of the therapeutic approach. It implies a portable use of ultrasound in acute settings covering different specified protocols, such as echocardiography, vascular, lung or abdominal ultrasound. This article reviews POCUS application in the emergency department or the intensive care unit, focused on severely compromised patients with cardiogenic shock with an emergent bedside assessment. Considering the high mortality rate of this entity, POCUS provides the intensivist/clinician with an appropriate tool for accurate diagnoses and a timely management plan. The authors propose practical algorithms for the diagnosis of patients using POCUS in these settings.2023-01-01T00:00:00ZUniportal video-assisted thoracoscopic surgery: Argentinian experienceBondulich, GustavoGonzalez Rivas, Diegohttps://repositorio.uca.edu.ar/handle/123456789/166312023-06-30T05:01:18Z2017-01-01T00:00:00ZTítulo : Uniportal video-assisted thoracoscopic surgery: Argentinian experience
Autor : Bondulich, Gustavo; Gonzalez Rivas, Diego
Resumen : Abstract: The acceptance of uniportal video-assisted thoracoscopic surgery (VATS) for minor and major
thoracic procedures is growing in South America. This study presents the experience with uniportal VATS in
Buenos Aires, Argentina. In a retrospective study, 181 patients were operated with uniportal VATS technique
between December 2013 and October 2016. Uniportal procedures included minor and major procedures.
Uniportal VATS were analyzed en terms of morbidity, mortality, conversion rate, hospital stay. A total of
181 patients were analyzed. 59% were males and 41% females. The mean age was 58.7. The uniportal VATS
procedures included pneumothorax 30, interstitial lung 5, complicated pleural effusion 35, pleurectomy
biopsy pleurodesis 40, pericardial effusion 10, mediastinal tumor (posterior) 5, wedge resection 30,
anatomical segment resection 6, and lobectomy 20. There were 2 conversions in major resection procedures
due to technical difficulties. There was 1 revision for postoperative hemothorax. The mean hospital stay
was 4.9 days for the whole group. Uniportal VATS is a safe technique in thoracic surgery. Maintains the
oncological principles of traditional open procedures. There are lower, few general complications, lower pain
level, lower postoperative morbidity and mortality. Reduces surgical trauma, and reduces the postoperative
hospital stay.2017-01-01T00:00:00ZAre the different cut-off points for sitting time associated with excess weight in adults?

Resumen : Abstract: Excess weight is increasing worldwide, and in Latin America more than half of the population is excess weight. One of the reasons for this increase has been excessive sitting time. Still, it remains to be seen whether there is an excessive amount of that time in Latin American adults. This study aimed to associate different sitting time cut-off points with the excess weight. Methods: Data from the Latin American Study of Nutrition and Health (ELANS), a cross-sectional population-based survey conducted in eight Latin American countries, were used. The excess weight indicators used were body mass index, and waist and neck circumferences. Sitting time was obtained using questionnaires and categorized at different cut-off points. Differences between sitting time categories (< 4 or ≥ 4; < 6 or ≥ 6; and < 8 or ≥ 8 hours/day) and excess weight were obtained by Student's t test for independent samples and the association between sitting time categories and different indicators of excess weight were obtained by logistic regression.
Results: The median of the sitting time was 420 min/day (IQR: 240-600). There were no significant differences between body mass index (kg/m2) and waist circumference (cm) with categories of sitting time. The mean values of neck circumference (cm) were significantly higher in ≥4, ≥6 and ≥ 8 hours/day than < 4, < 6, and < 8 hours/day of sitting time in the pooled sample. Some distinct differences by country were observed. There were significant differences among excess weight by body mass index (63.2% versus 60.8) with < 8 vs ≥8 hours/day of sitting time. The proportion of excess weight by neck circumference was higher in participants who reported ≥4, ≥6, and ≥ 8 hours/day compared to < 4, < 6, and < 8 hours/day of sitting time. Considering ≥8 hours/day of sitting time, higher odds of excess weight were found evaluated by body mass index (OR: 1.10; 95% CI: 1.01, 1.20) and neck circumference (OR: 1.13; CI 95%: 1.03, 1.24) overall.
Conclusions: Sitting time above 8 hours/day was associated with higher odds of excess weight, even though there were no differences in waist circumference between sitting time categories.2023-01-01T00:00:00Z
