The information of how safe we need to maintain to avoid COVID-19 transmission needs to be studied in detail. Eventhough virus RNA was found on surfaces, none were thought to be able to transmit disease. The larger droplets traveled farther compared to the smaller droplets. This was due to the increase drag on the smaller droplets. “Breathing out, singing, coughitng and sneezing generated warm moisr high momentum dropplets. These travel faster that the typical backgrund air ventilation flow.”
Biliopancreatic diversion with a duodenal switch for treatment of obesity , was first publisehd by Dr. Hess in 1998.

THe lessons of the Pandemic of 1918-1919 may be as relevant today as they were 100 years ago.
We’d like surgical patients are most effective in treatment of type two diabetes. However different weight loss surgical procedures have different outcomes.
Weight loss surgical procedures improve different aspects of metabolic syndrome. Therefore patients with a number of comorbidities and obesity may benefit better from weight loss surgery.
Duodenal switch operation is superior to gastric bypass for delivering long-term sustained weight loss. However in some patients this may be associated with increased incidence of undesirable side effects.
Duodenal switch operation is superior for resolution of metabolic comorbidities in obese patients. The improvement is even more pronounced for those patients with a body mass index over 50. However the difference is noted also for patients for a BMI of less than 50.
Arterial hypertension is strongly related to obesity. There may be different mechanisms which leads to hypertension in overweight patients. This may be the reason why the outcome of different surgical procedures varies between procedures.
Hypertension is closely linked to high prevalence of obesity. Surgical weight loss is the most promising option for long-term control of hypertension. However there are certain limitations to accessibility.
