Great answer above. This is to add on to it: Making a decision on whether to recommend screening tests for the entire population is different from deciding whether to screen an individual patient. The USPSTF uses panels of experts who employ extensive epidemiology and biostatistics and literature reviews to make those recommendations. At the population ...

Screening tests such as "blood tests and imaging" have two costs and one benefit: the cost (dollars and possible health problems) of the actual screening, which can in some cases be free the cost (dollars and possible health problems) of the followups required when the screening is positive the benefit of less people dying or their treatment being less ...

No. This line of reasoning expects infectious bacteria to be immobile on their own and "gums" to be isolated from one another in a regularly closed and healthily salivated mouth. If your practitioner would have put the probe into her own mouth before examining yours, then that would be a great way to spread whatever. Your own mouth is an ecosystem where ...

It's just a medical hypothesis that because BCG might offer some protection against viruses and bacterial infection, it might offer some protection against SARS-CoV-2. There is an Australian study in progress to see if it helps protect health workers. https://clinicaltrials.gov/ct2/show/NCT04327206 But given that BCG has been in world wide short supply ...

Physiology, Chemoreceptor Trigger Zone (StatPearls): Nausea and vomiting are controlled by the vomiting center in the medulla oblongata, which is located between the brainstem and spinal cord. The main part of the vomiting center is the chemoreceptor trigger zone (CTZ), also known as the area postrema (AP), which receives signals from: the blood (uremia, ...

I think the closest thing to a "standardization of drugs" are the pharmacopeia: USP European Pharmacopoeia Japanese Pharmacopoeia (just some examples) As you will notice, these are not global standards, but each one defines the parameters by which a drug is of adequate quality and purity to be deemed that drug. To generate a global standard, it would be ...

The idea that the International Statistical Classification of Diseases and Related Health Problems (ICD) forms an international standard on health problems is contentious within some groups of people when there is the Diagnostic and Statistical Manual of Mental Disorders (DSM), which cross-references the ICD and there can sometimes be conflicting criteria ...

Yes, nicotine replacement therapy is used in multiple forms, including a skin patch and oral dosing with gums and lozenges. The purpose is to help avoid the side effects of nicotine withdrawal, while delivering nicotine at lower doses than is obtained through smoking, to help manage craving and eventually stop smoking entirely. As far as the delivery ...

There is no known way to infect yourself with a "safe" dose of SARS-CoV-2. The eyes are listed as a portal of infection which is why health workers wear eye protection (goggles, face shields ). Once the virus infects human cells it starts to replicate creating more virus. At some stage the immune system will ramp up and detect the virus but this takes ...

HIV DNA PCR is found to be more specific for actual infection than RNA PCR . https://pubmed.ncbi.nlm.nih.gov/9951977/ I didn't read the whole thing I guess DNA PCR actually detects reverse transcriptase activity as not all person who are inoculated with virus get infection.Few lucky ones have receptor mutation.
