A dataset on skeletal muscle mass index, body composition and strength to determinate sarcopenia in bariatric patients

© 2023 The Authors. Published by Elsevier Inc. This is an open access article under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/)Bariatric surgery is the treatment for severe obesity, with proven efficacy in reducing weight. Weight loss associated with bariatric surgery is greatly associated with a significant reduction of skeletal muscle and bone mineral mass, which leads us to induce that after bariatric surgery, patients incur an increased risk of sarcopenia. Prophylactic programs that prevent sarcopenia in bariatric surgery patients seems to be one of the crucial points for the long-term surgical success of bariatric and metabolic surgery. This article presents a initial data set of skeletal muscle mass index, body composition and strength to determinate sarcopenia in bariatric patients. The data were collected in a Central Hospital and in the University. In total, is necessary to recruit 46 patients waiting for bariatric surgery, between 18 and 60 years, men, and woman, without contradiction for exercise. The patients are randomized in two groups, for exercise group and control group. The evaluation is made on five points of timeline, before the surgery, after the surgery, after de exercise program, six months, and twelve months after the exercise program.This work is funded by national funds through the Foundation for Science and Technology, under the project UIDP/04923/2020.info:eu-repo/semantics/publishedVersio

ß-Farnesene exogenous application as a novel damage induction model to fast explore the effectiveness of postharvest strategies: the case study of the ‘Rocha’ pear DOP

Since the prohibition of diphenylamine, replacement strategies have been needed for long-term disorder prevention, namely superficial scald (SC), in fruit. However, as this disorder only appears after months under cold storage, the assessment of effective strategies to prevent this disorder requires long periods. To tackle this challenge, we report in this paper a rapid and reliable system to induce symptoms, such as SC, based on storage under a β-farnesene-enriched atmosphere. Using this model, SC symptoms in ‘Rocha’ pear were induced after 15 d at 20◦ C. As proof of concept, this model system allowed the study of the efficiency of antioxidant natural-based coatings on ‘Rocha’ pear quality maintenance. Pears treated with the coatings were submitted to 4 months of commercial storage under normal atmosphere conditions and the results were compared with those obtained using the induction model system. A PCA of chemical data allowed us to conclude that the model developed simulates the potential of certain strategies to prevent disorders.info:eu-repo/semantics/publishedVersio

Strategies to preserve postharvest quality of horticultural crops and superficial scald control: from diphenylamine antioxidant usage to more recent approaches

Horticultural crops are vulnerable to several disorders, which affect their physiological and organoleptic quality. For about forty years, the control of physiological disorders (such as superficial scald) in horticultural crops, particularly in fruit, was achieved through the application of the antioxidant diphenylamine (DPA), usually combined with controlled atmosphere (CA) conditions. However, identification of DPA residues and metabolites in treated fruits, associated with thei toxicity, banned the use of this antioxidant in Europe. This triggered the urgent need for novel and, ideally, natural and sustainable alternatives, combined with adequate storage conditions to protect cultivars from harmful agents. This review systematizes the state-of-the-art DPA application on several fresh cultivars, such as apples, pears, and vegetables (potatoes, spinach, etc.), as well as the possible mechanisms of the action and effects of DPA, emphasizing its antioxidant properties. Alternative methods to DPA are also discussed, as well as respective effects and limitations. Recent research on scald development molecular pathways are highlighted to open new non-chemical strategies opportunities. This appraisal shows that most of the current solutions have not lead to satisfactory commercial results; thus, further research aimed to understand the mechanisms underlying postharvest disorders and to design sustainable and safe solutions to improve horticultural products storage is needed.info:eu-repo/semantics/publishedVersio

Profitability of Corn (Zea mays L.) Grown in Milpa Production Systems in Oaxaca, Puebla, and Veracruz, Mexico

OBJECTIVE: To compare the profitability of corn cultivation under the milpa system in Oaxaca, Puebla, and Veracruz. METHODOLOGY: A sample of 91 producers from Villa de Zaachila, Oaxaca, Chalchicomula de Sesma, Puebla, and Tequila, Veracruz, was interviewed about corn production by milpa production system. The average yields per hectare, costs, sale price and total income are compared, and the Cost Benefit Ratio (CBR) of the milpas in each municipality was interpreted. RESULTS: Maize production in Villa de Zaachila presented a modern agriculture with total production costs of 13,650 $ha-1, yield 2,257 kg ha-1, total income 23,429.27$ ha-1 and RBC 1.72. In Chalchicomula de Sesma, a traditional agriculture destined for commercialization to intermediaries, its total costs were 12,380 $ha-1, yield of 2,456 kg ha-1, total income 12,280.00$ ha-1 and RBC 0.99. In Tequila, a subsistence agricultural, with total production costs of 7,350 $ha-1, yield 964 kg ha-1, total income of 6,748.00$ ha-1 and RBC 0.92. STUDY LIMITATIONS: The data is taken from an exploratory sample, limited in time and space. Versions or productive practices not sampled could be omitted, with technical-economic specificities different from those presented in this study. CONCLUSIONS: The contrasting modifications in the structure, function, and logic of the milpa for the 2020-2021 cycle, allowed a profitable agroecosystem in Villa de Zaachila; however, it was not profitable in Chalchicomula de Sesma and Tequila.Objective: To compare the profitability of corn cultivation under the milpa production system in Oaxaca, Puebla, and Veracruz.Methodology: Ninety-one producers, from Villa de Zaachila, Oaxaca, Chalchicomula de Sesma, Puebla, and Tequila, Veracruz, Mexico, were interviewed about corn production in milpa production systems.

The impact of plant-based coatings in “ROCHA” pear preservation during cold storage: a metabolomic approach

Although new storage technologies have been emerging in recent years, preservation of pear (Pyrus communis L.) remains a challenge for suppliers. Maintenance of desired organoleptic properties throughout cold storage using non-chemical strategies has been investigated and the use of edible coatings has shown potential to delay fruit quality deterioration during cold storage. Thus, the objective of this study is to evaluate the impact of pectin coatings including plant extracts, in “Rocha” pear (Pyrus communis L. cv. Rocha) preservation. A four-month pilot scale assay was performed in both dynamic controlled atmosphere (DCA) (−0.5 °C, 0.5% O2, and 0.4% CO2) and normal atmospheric (NA) conditions (2 °C). For each storage condition, the following three coatings were tested: pectin (3% w/v) (PCT), pectin (3% w/v) + strawberry tree leaves extract (9.5 mg/mL) (CT1), and pectin (3% w/v) + apple pomace extract (16 mg/mL) (CT2). Volatile compounds, potentially related to aroma or ripening status of “Rocha” pear, were monitored alongside with conjugated trienols (CTs) and maturity parameters. The combination of DCA conditions and the application of pectin coatings were able to reduce the release of Rocha pear volatiles associated with ripening status, (particularly esters and sesquiterpenes), as well as reduce CTs, which could contribute to the preservation of Rocha pear for longer periods.info:eu-repo/semantics/publishedVersio
