Health condition keyword:

COVID-19

SARS-CoV2

Intervention(s):

Experimental group: Additional to the corresponding protective equipment, they will perform intranasal and oral disinfection with 0.0015%, Neutral Electrolyzed Water (SES). Intranasal disinfection consists of applying four shots of SES in each nostril (approximately 0.4 mL in each nostril), 3 times a day; Oral disinfection will be with mouthwashes that will be performed 3 times a day, with 10 mL of SES, for 60 seconds each. Both procedures will be performed during 4 weeks, which is the study follow-up period. Control group: Will wear the corresponding protective equipment, without performing oral / intranasal disinfection. Protective equipment: All health professionals enrolled in the study belong to the first line of care for patients with COVID-19 and will wear the corresponding protective equipment, being a surgical uniform, N95 mask, eye-sealing glasses and plastic wallet, disposable cap, gloves made of latex, rubber footwear for hospital use, disposable shoe covers. Additionally, health professionals from the third level of care will wear a full protective mask, Dermacare® overalls with 70 / polyethylene and 30 / polypropylene zipper with integrated hood with elastic cuffs and ankle, double disposable boot covers and double latex gloves. Likewise, frequent hand washing with liquid soap with 2% chlorhexidine gluconate and disinfection with a hand sanitizer solution with 0.05% chlorhexidine gluconate and 60-80% ethyl alcohol, and disinfection of secondary uniform and footwear with 80% ethyl alcohol and bath at the end of the working day, were performed.

Results Study

Section to complete the data related to the summarized results.

Summary study:

Beef is an excellent source of nutrients; unfortunately, most nutritional recommendations suggest limiting or even avoiding it. Studies have shown that the fatty acid composition of meat influences weight loss. This randomized controlled clinical trial evaluated the anthropometric and serum lipid changes after a food intervention that included frequent beef consumption (120 g consumed four days/week for four weeks). Volunteers were randomly assigned to the commercial or Wagyu-Cross beef groups, with the latter beef possessing higher fat and MUFA contents. Both groups exhibited reductions in body measurements and lipid profiles; however, the Wagyu-Cross group exhibited greater changes in weight (−3.75 vs. −2.90 kg) and BMI (−1.49 vs. −1.03) than the commercial group, without a significant difference between them. No significant group differences in lipid profiles were observed; however, the Wagyu-Cross group exhibited a more favorable change in decreasing the TC concentration (−7.00 mg/dL) and LDL-C concentration (−12.5 mg/dL). We suggest that high MUFA beef could be included in weight-loss programs since it does not affect weight loss and hasn’t a negative influence on lipid metabolism.
