Effect of a NSS to Reduce Complications in Patients With Covid-19 and Comorbidities in Stage III

Patients in the COVID-19 area, who are treated at the ISSEMYM Toluca Arturo Montiel Rojas Medical Center, located in Paseo Tollocan, Av. Baja Velocidad km 575, Barrio de Sta Clara, Toluca de Lerdo, México; both sexes, with the presence of comorbidities (type 2 DM, SAH, overweight or obesity BMI \<35) and in stage III of the disease. Consecutive cases. With systematic randomized allocation using a sequence of random numbers built with the Excel program divided into two groups. Once the participants of the COVID-19 area have been selected, patients and / or family members will be spoken to to explain the protocol and obtain the signatures of the letters of informed consent. Assignment to the research group will be carried out randomly. Once the patients have been admitted to the study, the following will be carried out: test of COVID-19 by means of PCR, thorax tomography, complete clinical history, Mini Nutritional Assessment (MNA), food diary, list of clinical variables designed by us, complete blood count, coagulation profile, serum electrolytes, blood chemistry (6-elements), lipidic profile, liver function tests, ferritin, fibrinogen, C-reactive protein, procalcitonin and D-dimer. Anthropometric measurements will also be carried out (height, weight, BMI, muscle mass %, fat % and visceral fat%). The follow-up will be carried out daily for 21 days or earlier, if they are discharged from the hospital due to improvement in the evolution, at that moment the patient concludes the study. The following points will be supervised, recording the information in files and photos, since the hospital security protocol does not allow to extract stationery from the COVID-19 area: 1. Application and consumption of NSS supplementation as appropriate. 2. Morning and evening vital signs. 3. Daily clinical evaluation (It includes variables such as oxygen flow, activity level, integrity of the hair, skin and nails, evaluation of the sense of taste and smell, pain, gastrointestinal symptoms, bowel movements, prescribed medications, mood, among others). 4. Anthropometric measurements using a scale every 2 days (only if the patient is stable and can maintain balance). 5. Food diaries of each patient. 6. Laboratory studies every 3 days (previously mentioned). In the same way, the following will be taken into account: the number of days hospitalized, number of patients who progress to ventilation, number of patients who die, number of patients who are extubated and number of days after extubation. A descriptive analysis will be carried out for each continuous variable. These variables will be expressed as mean ± standard deviation and standard error. It will be done according to the distribution of the data; For independent groups with a normal distribution, Student's T will be applied. If the distribution does not meet normality criteria, a Mann Whitney U will be performed; For the follow-up of dependent groups with normal distribution, two-way ANOVA will be applied. If the distribution does not meet normality criteria, a Friedman test will be performed, in both cases post hoc tests will be performed, taking into account that a significant value of p of \< 0.05. The results will be analyzed using version 6 of the Graphpad Prism software.
