Vitamin D, Calcium, and Cancer

August 14, 2007

Summarized by Robert W. Griffith, MD

Summary
In a prospective randomized study, calcium-plus-vitamin D capsules significantly reduced the risk of cancers of different types in postmenopausal women.

Introduction
It’s been known for more than 50 years that exposure to the sun’s rays protects against some cancers – breast, rectum, ovary, prostate, stomach, bladder, esophagus, kidney, lung, pancreas, and uterus, as well as non-Hodgkin lymphoma and multiple myeloma. Researchers first proposed that vitamin D was responsible 25 years ago. Since then, associations have been found between colorectal and prostate cancer and low blood levels of vitamin D. All these findings are based on what are called “observational studies”. Now a double-blind, placebo-controlled trial of calcium and vitamin D supplementation has been done, in which the occurrence of cancer was an important outcome. Its findings have been published in the American Journal of Clinical Nutrition, and are summarized below.

Acupuncture for Hypertension – Is It Feasible?

August 13, 2007

Summarized by Robert W. Griffith, MD

Summary

In the study summarized here, acupuncture given by experienced Chinese clinicians to patients with hypertension produces significant reductions in systolic and diastolic blood pressure. The beneficial effect does not persist after the 6-week treatment period, and conflicts with a recently reported study of similar design.

Introduction

There have been many reports that acupuncture can lower blood pressure in hypertensive patients, but these are rarely well-controlled, randomized, blinded studies, which represent the gold standard for demonstrating effectiveness of a treatment. One of the most recent controlled trials, reported in 2006, showed no benefit of acupuncture over a sham procedure, and the approach is not widely used in Western therapeutics.1 However, a new study, this time from Germany, has found a significant benefit of the procedure over a 6-week period in hypertensives. It’s reported in the journal Circulation , and we summarize it here.

Migraine With Aura Linked To Stroke Risk In Women, US Study

August 11, 2007

A new US study suggests that women who have migraines with aura (seeing spots and flashing lights), particularly those who smoke or use oral contraceptives, are at increased risk of having a stroke compared with women who do not have migraines.

The study is published in Stroke, a journal of the American Heart Association, and was carried out by researchers from the University of Maryland School of Medicine, Baltimore, Maryland, the VA Maryland Health Care System, also in Baltimore, and the US Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia.
