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.”
Risk of SARS-CoV-2 transmission from asymptomatic people in different settings and for different occupation times, venting, and crowding levels (ignoring variation in susceptibility and viral shedding rates). Face covering refers to those for the general population and not high grade respirators. The grades are indicative of qualitative relative risk and do not represent a quantitative measure. Other factors not presented in these tables may also need to be taken into account when considering transmission risk, including viral load of an infected person and people’s susceptibility to infection. Coughing or sneezing, even if these are due to irritation or allergies while asymptomatic, would exacerbate risk of exposure across an indoor space, regardless of ventilation
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.
