ABSTRACT
Horticulture, with its different disciplines (Horticulture/Olericulture, Fruit-growing, Aromatic-Medicinal and Floriculture), has become more relevant, since the Covid-19 pandemic, with a greater appreciation of products from short chains. The objective was to evaluate the degree of knowledge, behavior and preferences of Latin American consumers, regarding the safety, quality and origin of local fruits and vegetables (F&H) produced and consumed within a radius of no more than 100 km, differentiated with the "Km 0” logo. An online survey was generated (GoogleForms): Study on the Latin American production and consumption of "Km 0" fruits and vegetables, within the framework of inter-institutional links (UNCPBA, UNMDP, UNSL, UCA and INTA CERBAS Area, from Argentina;UdelaR, Uruguay;UNAL and UniSalle, Colombia;BUAP, Mexico;UFRRJ, Brazil), from 03/09/2022 to 07/12/2022. The main topics were: Degree of knowledge of the F&H category "Km 0”;Perceived benefits;Predisposition to consume and acquire them;Degree of evaluation of the "Km 0” labelling;and dissemination campaigns;Places of purchase and changes since the pandemic;Valuation of having lists of local producers of F&H "Km 0”;Knowledge of the place of production of the F&H and assessment of the promotion of local productions;Knowledge of GAP;Acquired food and Assessment of the origin of F&H consumed. The surveys answered were 1127. Ignorance of the "Km 0” category was detected (60%), low consumption of F&H (17% consume 5 ≥ portions/day) although there is a high assessment of F&H in the diet (80%). The need for permanent training and dissemination, of the production and consumption of safe and quality F&H, in quantity and diversity, was evidenced. The pandemic was a turning point from which consumers became aware of the importance of the origin of the products consumed, preferring local F&H. © 2022, Asociacion Argentina de Horticultura - ASAHO.

ABSTRACT
As of 14 December 2021, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), caused nearly 269 million confirmed cases and almost 5.3 million deaths worldwide. Chest computed tomography (CT) has high diagnostic sensitivity for the detection of pulmonary disease in COVID-19 patients. Toward timely and accurate clinical evaluation and prognostication, radiomic analyses of CT images have been explored to investigate the correlation of imaging and non-imaging clinical manifestations and outcomes. Delta (∆) radiomics optimally performed from pre-infection to the post-critical phase, requires baseline data typically not obtained in clinical settings;additionally, their robustness is affected by differences in acquisition protocols. In this work, we investigated the reliability, sensitivity, and stability of whole-lung radiomic features of CT images of nonhuman primates either mock-exposed or exposed to SARS-CoV-2 to study imaging biomarkers of SARS-CoV-2 infection. Images were acquired at a pre-exposure baseline and post-exposure days, and lung fields were segmented. The reliability of radiomic features was assessed, and the dynamic range of each feature was compared to the maximum normal intra-subject variation and ranked. © 2022 SPIE
ABSTRACT
The production of micro vegetables or microgreens and of sprouts is an interesting alternative for the optimization of vegetable consumption admitting great diversity and feasibility at a family as well as a commercial level, and whose consumption provides multiple benefits. Both options have productive potential for entrepreneurs, especially in the Km 0 due to immediate consumption. These productive alternatives contain several times more nutrients than their adult counterparts and can be obtained by sustainable production means, as in the case of microgreens in the presence of light or sprouts in darkness. Both foster greater nutrient bioavailability which helps to increase immunity, decrease vulnerability to diseases and contribute to a better physical and mental development of the population. In this sense, in the current global and national socioeconomical and sanitary context due to Covid-19 pandemics where the optimization of consumption of food which promotes optimal nutrition becomes a challenge, this review article is carried out in order to show a panorama of the peculiarities and benefits of consumption as well as the potential market, especially as Km 0 products, of two innovative alternatives of production (microgreens and sprouts) which admit great biodiversity and to contribute to promote their production and consumption.
ABSTRACT
Vegetable consumption has become relevant in the present global socio-economical and sanitary context. Consequently, the need to have a dynamic diagnosis in Latin American countries arises in order to guide actions of spreading vegetable and fruit production and consumption. Therefore, a survey was carried out in 12 Latin American countries with 518 respondents. This survey was driven by the Horticulture teams of the Latin American universities: Universidad Nacional del Centro de la Provincia de Buenos Aires (UNCPBA), Argentina, Benemerita Universidad Autonoma de Puebla (BUAP), Mexico, Universidad Nacional de Colombia (UNAL) and Universidad Nacional de San Luis (UNSL) Argentina, within the framework of their projects and interinstitutional bonds. The survey aimed at having an updated panorama about the reality of vegetable production and consumption, preferences, habits of consumption and changes produced in the Latin American population's diet due to the COVID-19 global pandemics. The results obtained show the existence of differences between perception and the reality of the population's consumption generating the need to drive actions to produce coincidence of what the population believes it consumes with what it actually does, so as to have a diet rich in quantity, quality and diversity of vegetables that benefits its health and life quality and reduces the risk of developing potential illnesses.
ABSTRACT
Objective: To analyze the complications developed in patients with COVID-19 supported with ECMO and to evaluate their impact in outcomes. Methods: Prospective observational study including all the COVID-19 patients with ECMO support in the ICU of the VHUH from 15 March to 30 July. Infectious, renal, thrombotic, hemorrhagic and other complications during support were prospectively registered. Continuous variables expressed as median (interquartile range) and categorical variables as number (percentage). The impact of complications in mortality was analyzed using Chi-squared or Fisheŕs exact test as appropriate. Results: Twenty-four patients [55 (46-57) years, 58% male, BMI 32.1 (27-35)] received ECMO support [23 (96%) VV-ECMO] during 11 (5.7-19.2) days. The longest run lasted 67 days (awake ECMO). Eighteen (75%) patients could be decannulated and 16 (67%) were discharged alive from the ICU. Fifteen (63%) patients suffered hemorrhagic complications and 12 (48%) thrombotic events, with 7 (29%) patients needing circuit change. Ventilator-associated pneumonia (VAP) was diagnosed in 8 (33%) patients and acute kidney injury (AKI) in 7 (29%). Other complications were air leak (5 patients), fungal infection (4), CMV replication (3) and cardiac tamponade (1). Hemorrhage and thrombosis were not associated with mortality (P=1.0 and P=0.6, respectively). VAP and AKI were neither associated with mortality (P=0.3 both). Conclusions: Complications are frequent in COVID-19 patients supported with ECMO, especially thrombotic and hemorrhagic. VAP and AKI might be studied in further studies to confirm their association with a higher risk of mortality.
