Neck manipulation may be associated with stroke

Treatments involving neck manipulation may be associated with stroke, though it cannot be said with certainty that neck manipulation causes strokes, according to a new scientific statement published in the American Heart Association’s journal Stroke. Cervical artery dissection (CD) is a small tear in the layers of artery walls in the neck. It can result in ischemic stroke if a blood clot forms after a trivial or major trauma in the neck and later causes blockage of a blood vessel in the brain…

Five daily portions of fruit and vegetables may be enough to lower risk of early death

These results conflict with a recent study published in BMJ’s Journal of Epidemiology and Community Health suggesting that seven or more daily portions of fruits and vegetables were linked to lowest risk of death. There is growing evidence that increasing fruit and vegetable consumption is related to a lower risk of death from cardiovascular disease and cancer. However, the results are not entirely consistent. …

Drug may aid multiple myeloma patients who suffer from low platelet counts

In a July 25, 2014, article in The Journal of Clinical Investigation online, the researchers show that when the proteasome, which is a protein complex that breaks down the proteins that regulate cellular processes, is pharmaceutically inhibited platelet production in human and mice cells was blocked. Platelets are cells that bind together and help induce clotting to stop bleeding. The researchers also show that Fasudil, a drug approved for use outside of the United States but not in this country, restored platelet counts in adult mice whose proteasome activity had been suppressed by administering bortezomib and by knocking out a particular gene. …

Immune therapy might be effective for multiple myeloma

The researchers modified a type of human immune cell — called T lymphocytes, or T cells — to target a molecule called CS1, which is found on more than 95 percent of myeloma cells, and to kill the cells. The researchers grew the modified cells in the lab to increase their numbers and then injected them into an animal model where they again killed human myeloma cells. The findings were published in the journal Clinical Cancer Research…

Gut microbes turn carbs into colorectal cancer, study shows

“Because hereditary colorectal cancer is associated with aggressive and rapid tumor development, it is critical to understand how major environmental factors such as microbes and diet interact with genetic factors to potentially affect disease progression,” says senior study author Alberto Martin of the University of Toronto. “Our study provides novel insights into this question by showing that gut bacteria interact with a carbohydrate-rich diet to stimulate a prevalent type of hereditary colon cancer.” Carbohydrates account for about half of the daily caloric intake of adults on a western-style diet, and previous studies have linked carbohydrate-rich diets to colorectal cancer in humans. This type of cancer is also frequently associated with mutations in a tumor suppressor gene called APC as well as the MSH2 gene, which plays a critical role in repairing DNA damage…

Negative HPV test may predict lower cervical cancer risk than a negative Pap

In a comparison of the three strategies, Julia C. Gage, Ph.D., M.P.H., of the Division of Cancer Epidemiology and Genetics, National Cancer Institute, Bethesda, MD, and colleagues analyzed data from the Kaiser Permanente Northern California (KPNC) large integrated health delivery system, which screened women age 30-64 since 2003 with both HPV and Pap testing. Data were available through 2012, and over 1 million women were screened at approximately 3-year intervals, with a mean follow-up time of 4.36 years. For each testing strategy, they estimated the cumulative risk of cervical cancer after a negative test result. …

Test increases odds of correct surgery for thyroid cancer patients

The test, available at the UPMC/UPCI Multidisciplinary Thyroid Center and other diagnostic testing agencies, improved the chances of patients getting the correct initial surgery by 30 percent, according to the study published this month in the Annals of Surgery. “Before this test, about one in five potential thyroid cancer cases couldn’t be diagnosed without an operation to remove a portion of the thyroid,” said lead author Linwah Yip, M.D., assistant professor of surgery in Pitt’s School of Medicine and UPMC surgical oncologist…

Lacking trust in one’s doctor affects health of emotionally vulnerable cancer patients

Patients who feel anxious and uneasy with their doctor may be impacted the most. “Anxiously attached patients may experience and report more physical and emotional problems when the relationship with their physician is perceived as less trusting,” said Chris Hinnen, Ph.D., lead author and clinical psychologist at Slotervaart Hospital in Amsterdam, The Netherlands. The researchers acknowledge that the issue of trust between patients and their doctors can be complicated, but observe that it’s important to understand fears of rejection and abandonment that often exist in anxiously attached patients. Hinnen and his colleagues analyzed questionnaire responses from 119 participants with breast, cervical, intestinal or prostate cancers at 3, 9 and 15 months after their diagnosis. …
