“Of the 211 women without symptoms, all were afebrile on admission. Nasopharyngeal swabs were obtained from 210 of the 211 women (99.5%) who did not have symptoms of Covid-19; of these women, 29 (13.7%) were positive for SARS-CoV-2. Thus, 29 of the 33 patients who were positive for SARS-CoV-2 at admission (87.9%) had no symptoms of Covid-19 at presentation.”

Is genetic diversity more resilient to developing severe forms of covid19 at a population level?
Virus particles are small - they replicate fast - as part of replication they damage cells - they then enter adjacent cells - they basically over time will make their own access route. It seems some strains replicate faster than other ones, and so they will be the ones I’m guessing that are causing more of the non lung / non intestinal issues?

Clinical Considerations

Pg 30 - Handbook of Covid-19 Prevention and Treatment, Zhejiang University School of Medicine.
-
Prevention of Regurgitation and Aspiration - Gastric residual volume and gastrointestinal function should be routinely evaluated. Appropriate enteral nutrition is recommended to be given as earlier as possible. Nasointestinal feeding and continuous nasogastric decompression are recommended. Enteral nutrition should be suspended and aspiration with 50 mL syringe be done before transfer. If no contraindication exists, a 30° semi-sitting position is recommended
+ - Fluid Management - Excessive fluid burden worsens hypoxemia in COVID-19 patients. To reduce pulmonary exudation and improve oxygenation, the amount of fluid should be strictly controlled while ensuring the patient’s perfusion.
-
So Parenteral Nutrition is Contraindicated?
+ - GI Considerations
-
+ - Some COVID-19 patients have gastrointestinal symptoms (such as abdominal pain and diarrhea) due to direct viral infection of the intestinal mucosa or antiviral and anti-infective drugs. There have been reports that the intestinal micro ecological balance is broken in COVID-19 patients, manifesting a significant reduction of the intestinal probiotics such as lactobacillus and bifidobacterium. An intestinal microecological imbalance may lead to bacterial translocation and secondary infection, so it is important to maintain the balance of intestinal microecology by microecological modulator and nutritional support.
-
+ - GI Infection by nCov19 leads to worsening states over time due to spread of bacteria from the intestines.

Unhealthy Gut Bacteria Populations hence preventing translocation.

This requires microbiome support
+ - The severe and critically ill COVID-19 patients who are in a state of severe stress are at high nutritional risks. Early evaluations of nutrition risk, gastrointestinal functions and aspiration risks, and timely enteral nutritional support are important to the patient’s prognosis.
-
Is there a case study for this?
+ - Enteral nutrition pathway. Severe and critically ill patients often harbor acute gastrointestinal damages, manifested as abdominal distension, diarrhea, and gastroparesis.
-
+ - Oral feeding is preferred. The early intestinal nutrition can provide nutritional support, nourish intestines, improve intestinal mucosal barrier and intestinal immunity, and maintain intestinal microecology
-
This prevents translocation of bacteria
For patients with tracheal intubation, intestinal nutrition tube indwelling is recommended for post-pyloric feeding
-
+ - Selection of nutrient solution
-
For patients with intestinal damage, predigested short peptide preparations, which are easy for intestinal absorption and utilization, are recommended
For patients with good intestinal functions, whole-protein preparations with relatively high calories can be selected.
For hyperglycemia patients, nutritional preparations which are beneficial to glycemic controlling are recommended
+ - Energy Considerations
-
Energy supply. 25-30 kcal per kg body weight, the target protein content is 1.2-2.0 g/kg daily.
+ - Means of nutritional supply
-
+ - Pump infusion of nutrients can be used at a uniform speed, starting with a low dosage and gradually increasing.
-
When possible, the nutrients can be heated before feeding to reduce intolerance
+ - Note: VBF May be better?
-
Why in this particular condition?
The elderly patients who are at high aspiration risks or patients with apparent abdominal distention can be supported by parenteral nutrition temporarily. It can be gradually replaced by independent diet or enteral nutrition after their condition improves
