Cuff inflation Hypertension
Some home blood pressure measuring instruments, particularly ones that are less expensive, require the patient to manually inflate the cuff. When the cuff is manually inflated, the muscular activity used to inflate the cuff can acutely raise the BP by as much as 12/9 mmHg, an effect that dissipates within 5 to 20 seconds. Inflate the cuff to 30 mmHg above systolic pressure. Allow the sphygmomanometer to fall 2 to 3 mmHg per heartbeat This gives you accurate measurement and makes exertional effect disappear.
It is the flu season and many parts of the world, including India, are reporting flu cases, both as an outbreak or an epidemic. The flu virus is highly contagious and one infected person spreads the flu virus to around four more people. A person with flu is most contagious one day before the onset of symptoms and 5-7 days after becoming sick. After exposure to the virus, symptoms appear within 1 to 4 days. The flu virus spreads mainly via airborne droplets made when a person with flu sneezes, coughs or even talks. People with flu can spread it to others at a distance of up to 6 feet. Transmission is further facilitated in closed and crowded areas, especially when a number of people share the space and are in close proximity such as schools, offices or healthcare establishments. In such situations, the virus spreads easily and the attack rates are high. The virus can also be spread by touching a surface or object that has been contaminated with the flu virus. Hand washing is also very important in preventing the spread of flu.
Flu is a preventable disease. Observing appropriate precautions can prevent spread of the virus to others at home, school, work place, or in a public place. Avoiding exposure to the virus is the basic premise of flu prevention. Staying at home when sick with flu will ideally reduce the spread of virus to others. But, this is not always possible, especially for the working people.
Many employees report to work as they may not have paid sick leave. So, they are hesitant to take time off from work even when sick with the flu. The result is that they expose their colleagues to the virus, who will also, in turn, become infected and report to work sick.
Tooth Paste Ingredient
An ingredient commonly found in toothpaste could be employed as an anti-malarial drug against strains of the malaria parasite that have grown resistant to one of the currently used drugs. This discovery, led by researchers at the University of Cambridge, was aided by Eve, an artificially-intelligent ‘robot scientist’. When a mosquito infected with malaria parasites bites someone, it transfers the parasites into their bloodstream via its saliva. These parasites work their way into the liver, where they mature and reproduce.
After a few days, the parasites leave the liver and hijack red blood cells, where they continue to multiply, spreading around the body and causing symptoms, including potentially life-threatening complications.
Malaria kills over half a million people each year, predominantly in Africa and south-east Asia. While a number of medicines are used to treat the disease, malaria parasites are growing increasingly resistant to these drugs, raising the spectre of untreatable malaria in the future
Johns Hopkins Kimmel Cancer Center researchers developed a single blood test that screens for eight common cancer types and helps identify the location of cancer. The test, called CancerSEEK, is a unique noninvasive, multianalyte test that simultaneously evaluates levels of eight cancer proteins and the presence of cancer gene mutations from circulating DNA in the blood. The test is aimed at screening for eight common cancer types that account for more than 60 percent of cancer deaths in the U.S. Five of the cancers covered by the test currently have no screening test.
“The use of a combination of selected biomarkers for early detection has the potential to change the way we screen for cancer, and it is based on the same rationale for using combinations of drugs to treat cancers,” says Nickolas Papadopoulos, Ph.D., senior author, and professor of oncology and pathology.
