Two items relevant to long COVID

One of the tricky issues in studying in long COVID is: how widely do researchers cast their net? Initial reports acknowledged that people who were hospitalized and in intensive care may take a while to get back on their feet. But the number of people who had SARS-CoV-2 infections and were NOT hospitalized, yet experienced lingering symptoms, may be greater. A recent report from the United Kingdom, published in PLOS Medicine, studied more than Read more

Signature of success for an HIV vaccine?

Efforts to produce a vaccine against HIV/AIDS have been sustained for more than a decade by a single, modest success: the RV144 clinical trial in Thailand, whose results were reported in 2009. Now Emory, Harvard and Case Western Reserve scientists have identified a gene activity signature that may explain why the vaccine regimen in the RV144 study was protective in some individuals, while other HIV vaccine studies were not successful. The researchers think that this signature, Read more

Band posts salivary gland cancer news on web

In the news this week are reports that a member of the Beastie Boys hip-hop band announced on YouTube that he has salivary gland cancer – specifically of the parotid gland.

The public does not hear much about this type of cancer, and according to the American Cancer Society salivary gland cancers account for less than 1 percent of all cancers in the United States. About two out of three salivary gland cancers are found in people who are 55 or older. The average age at the time this cancer is found is 64.

The salivary gland is important because it Ray Ban outlet produces saliva, which contains enzymes that begin the process of breaking down food. It also contains substances to help prevent infections of the mouth and throat.

According to Emory Winship Cancer Institute expert Dong Shin, MD, the parotid glands are found in front of and just below each ear and most major salivary gland tumors begin in these glands.

Shin says that salivary gland tumors exhibit two major growth patterns: low grade, which is slow growing and more easily treatable, and high grade, which is usually a faster growing, more aggressive cancer that can also invade the lymph nodes. Certain types of salivary gland tumors can recur or have distant metastasis, particularly to the lungs.

Although the causes of this cancer are not definitively identified, Shin notes, there are some risk factors, including a history of radiation therapy to the head and neck area and a history being exposed to certain chemical substances, most often in the workplace.

Treatment usually includes surgery with radiation therapy afterward. Certain aggressive cell types require chemotherapy as well as radiation. However, explains Shin, at this time there are no specific chemotherapy agents that work well in attacking salivary gland tumors. Recent http://www.gafasraybanoutletes.com/ clinical trials have shown evidence of a fair response to certain molecular targeted chemotherapy, but more research is needed on these targeted therapies. wxjy6rbm4s
