A PICC is a long, thin, flexible tube known as a catheter. It is inserted into one of the large veins of the arm near the bend of the elbow. It is then slid into the vein until the tip sits in a large vein just above the heart.
The space in the middle of the tube is called the lumen. Sometimes the tube has two or three lumens (known as double or triple lumen). This allows different treatments to be given at the same time. At the end of the tube outside the body, each lumen has a special cap, to which a drip line or syringe can be attached. Sometimes there is a clamp to keep the tube closed when it is not in use.


The study, led by Suman Jayadev, M. D., of the University of Washington, Seattle, has stated that Alzheimer’
s disease is hereditary and identifying genes in patients can help detect others who are at risk for the condition.

Despite new health study suggestive that the inject diabetes drug LANTUS that power boost cancer risk and U.S. Food and Drug Administration on Wednesday urge patients who are on medicine to persist use it. And the three of four studies available most recent Friday in DIABETOLOGIA show a possible link between LANTUS and better risks for a variety of tumor type.
But, “the duration of patient follow-up in all four studies was shorter than what is generally considered necessary to evaluate for cancer risk from drug exposure,” the FDA said in its first comment on the issue. “Further, inconsistencies in findings within and across individual studies raise concerns as to whether an association between the use of insulin glargine and cancer truly exists.”
“Based on the currently available data, the FDA recommends that patients should not stop taking their insulin therapy without consulting a physician, since uncontrolled blood sugar levels can have both immediate and long-term serious adverse effects,” the agency wrote.
And “For patients using glargine and considering switching to another form of insulin, the data in these studies make it unclear as to whether any one type of insulin increases the risk of cancer more than other types of insulin,” the ADA said.

A cancer drug that destroys the deadly cells which give birth to tumours has been developed by scientists.
It has worked already in tackling breast cancer and offers hope to those with the disease in their prostate, skin or bowel.
The drug selectively kills cancer stem cells which help tumours grow and spread the disease through the body. Unlike other cancer cells, stem ‘mother’ cells are resistant to radiotherapy and
chemotherapy, allowing cancer to return after treatment.In laboratory tests, the new drug, salinomycin, was 100 times more effective at destroying stem cells than the powerful chemo treatment Taxol.
Injected into mice with breast cancer, it also slowed the growth of tumours.
Stem cells treated with the new drug
were less able to start tumours in the animals than cells treated with Taxol, the journal Cell reports.
The U.S. researchers believe dozens of drugs with similar properties could be developed over the next few years. The treatment is around a decade away from the market.
The new drugs could be used in combination with standard therapies to mop up cancer stem cells left behind by traditional treatment.
This would cut the odds of the cancer coming back.
They could also be used to halt the spread of the disease through the body. This is the most common cause of death in the 155,000 cancer patients who die each year.
Piyush Gupta, of the Broad Institute of the Massachusetts Institute of
Technology and Harvard, said: ‘It wasn’t clear it would be possible to find compounds that selectively kill cancer stem cells. We’ve shown it can be done.
‘Our work reveals the biological effects of targeting cancer stem cells
