Positive effect of vitamin A on cancer risk

Less than a month ago I summarized the results of a study where taking vitamin A was associated with increased risk of death. The significance of the results was debatable, but the headline was clear.

Now, researchers from the Karolinska Institute in Stockholm report “High intakes of vitamin A, retinol, and provitamin A carotenoids may reduce the risk of gastric cancer.”

Confused?

Zinc supplements in patients with head and neck cancer

Here’s a report (see page 113) from the 2007 Multidisciplinary Head and Neck Cancer Symposium.

Researchers at the North Central Cancer Treatment Group (NCCTG) conducted a double-blind, placebo-controlled trial to determine the value of zinc in preventing taste alterations (dysgeusia) in patients with head and neck cancer who were undergoing radiation therapy.

Here are the details.

  • 169 patients randomly assigned to zinc sulfate 45 mg by mouth 3 times/day, vs placebo administered throughout radiation to the posterior oropharynx and for one month after.
  • 81% of patients experienced taste alterations: 61 of those taking zinc and 71 taking placebo.
  • Time to taste alteration was 2.3 weeks with zinc vs 1.6 weeks in the placebo arm.

Although patients taking zinc had a delay in the onset of altered taste, the difference was not statistically significant. Therefore, the researchers concluded that zinc at the doses studied failed to prevent taste alterations in patients undergoing radiation-based treatment regimens for head and neck cancer.

The results differ from an earlier study in patients with dysgeusia that was not associated with cancer or other diseases.

Evaluating omega-3 polyunsaturated fatty acid supplementation for joint pain

A literature review by two researchers at York University in Toronto “suggest[s] that omega-3 PUFAs are an attractive adjunctive treatment for joint pain associated with rheumatoid arthritis, inflammatory bowel disease, and dysmenorrhea [painful menstruation].”

Results were positive for most measures of outcome.

Patient-controlled acupressure to treat nausea and vomiting after surgery

The Society for Ambulatory Anesthesia lists acupressure at the P6 meridian point (illustration) as an effective treatment for controlling nausea and vomiting following surgery.

Now, this study reports that patient-controlled acupressure helped control nausea and vomiting in patients receiving patient-controlled analgesia with morphine after gynecological surgery.
