An association between manipulative treatment and decreases in arterial blood pressure has been observed in the past. In some cases, reduction in blood pressure after manipulation has been so dramatic as to induce a call for the monitoring of medicated high blood pressure patients. A recent study published in the Journal of Manipulative and Physiological Therapeutics tests the hypothesis that there is a significant measurable change in blood pressure after upper neck adjustment.

Two tests were performed to check such a theory. In the first test, data was compiled from 40 patients demonstrating signs of upper neck joint dysfunction compared and compared with data from 40 patients without such symptoms. All participants were subjected to a resting and manipulation period in which their blood pressures were observed before and after as to changes in blood circulation rates. The second test involved 30 patients with upper neck joint dysfunction, under the same conditions, in which they acted as their own controls. Test one of this study revealed a statistically significant decrease in blood pressure between the treatment group and the nontreated group. Test two showed a statistically substantial decrease in systolic blood pressure from the postrest reading to the postadjustment reading.

“The results indicated that chiropractic adjustment causes a significant decrease in blood pressure in patients with supposed upper neck joint dysfunction in comparison with resting controls,” stated lead investigator Dr. Gary Knutson of Indiana University.

If you have high systolic blood pressure, talk to your doctor about what steps you can take to ensure optimal health. For more information about the benefits of chiropractic care, visit https://www.chiroweb.com/find/tellmeabout.

Common Headache Medicines Harmful to Unborn Babies?

The use of nonsteroidal anti-inflammatory drugs (NSAIDs) by pregnant women, such as ibuprofen and aspirin is strongly associated with the development of persistent hypertension of the newborn (PPHN), more commonly known as high blood pressure.

Case in point: A recent study in Pediatrics compared 101 newborns, 40 whom had PPHN. The infants’ blood pressures were evaluated, as was the history of NSAID use by their mothers. The results were then analyzed and compared. The results showed that 49.5% the women used some form of NSAIDs during pregnancy. Aspirin was used most frequently, followed by ibuprofen and naxproxen (found in Aleve and arthritis pills). A significant association was found between NSAID use by mothers and PPHN in their infants, which led to persistent high blood pressure in the newborns.

“It’s clear that pregnant women are not getting the message,” said lead investigator Dr. Enrique Ostrea. “They may not know that such anti-inflammatory drugs are NSAIDs because they can come in a combination of drugs.”

Product warnings on NSAIDs must be more prominent, as pregnant women may not be aware of such a problem. The following is an example of a warning from the box of a well-accepted ibuprofen box, “it is especially important not to use ibuprofen during the last three months of pregnancy unless specifically directed to do so by a doctor because it may cause problems in the unborn child or complications during delivery.”

If you are expecting a child, talk to your doctor about what steps you can take to ensure a smooth pregnancy and delivery. For more information on women’s health, visit https://www.chiroweb.com/tyh/women.html.

Adding Resistance to Your Aerobics

Step aerobics exercisers can stretch the benefits of their workouts by tugging on supersized rubber bands, according to a new study published in Medicine & Science in Sports and Exercise.

“Straining against the stretch cords has the same effect as weight training, which promotes muscle growth in a way that simply bounding up and down on a step platform cannot match,” said lead reporter Dr. William Kraemer of Ball State University in Muncie, Indiana.

The study looked at 35 healthy, active women who were divided into four groups. One group took part in a 25-minute step class; another a 40-minute step class; a third took part in 25 minutes of step, plus the stretch-band resistance work; and the last group was assigned no exercise. The program lasted for 12 weeks, after which sophisticated imaging scans were taken to evaluate muscle increases in each group.

All training groups improved their aerobic capacity between 12 and 18 percent, with the step-and-resistance group experiencing the biggest increase. The step-and-resistance exercisers also gained more upper body strength and endurance than the other groups.

The addition of resistance training to an exercise routine appears to do the job measurably better than aerobic exercise alone, and adds benefits to the upper body. “If you don’t have time for separate aerobics and strength sessions at a health club, you can combine them into one class and get similar gains,” said Dr. Kraemer.

The Choice Is Hers

Postmenopausal women who use estrogen replacement therapy may be at risk of suffering a fatality as a result of ovarian cancer, a new study reports. According to The Journal of The American Medical Association, women who used estrogen for at least 10 years after menopause were about twice as likely to develop ovarian cancer as their peers who did not take estrogen. There are pros and cons to postmenopausal estrogen. It can decrease women’s risk of bone-thinning osteoporosis, and treat hot flashes and other menopausal symptoms.

There are also suggestions that estrogen may decrease women’s risk of heart disease and colon cancer. Negatively, it can increase the risk of uterine cancer, and long-term use can increase the risk of breast cancer.

An association between estrogen use and ovarian cancer had not been examined, so lead investigator Dr. Carmen Rodriguez began studying 211,581 postmenopausal women in 1982. By 1996, 944 of the women had died of ovarian cancer. Dr. Rodriguez then compared the deaths between estrogen users and nonusers.

“Using estrogen for just a few years didn’t increase women’s risk. But women who used estrogen for ten or more years had double the risk of dying of ovarian cancer than women who never used the hormone,” Rodriguez said. Some 27,000 American women will be diagnosed with ovarian cancer this year, and 14,500 will die, the American Cancer Society estimates.

To put the increased risk into context, 43 of every 100, 000 women 65 or older will die of ovarian cancer each year, compared with 414 dying of heart disease. So even with a doubled ovarian risk, some older women may find estrogen’s possible cardiac protection a good tradeoff, while a woman with ovarian cancer in the family might not. For those who find their post-menopausal symptoms return, it’s a matter of risks vs. benefits regarding long-term use.

Bolstering Chiropractic Through Acupuncture

About 10 percent of U.S. chiropractors incorporate acupuncture into their practices. A recent study in the European Journal of Chiropractic surveyed 720 members of the British Chiropractic Association to access the use of acupuncture in their practices.

Ninety-three percent of the cases studied maintained chiropractic as their primary method of treatment, however, there were 61 conditions treated by chiropractors using the stimulation of acupuncture points without any manipulation. The study’s researchers noted that almost all of these conditions could be seen as being classically appropriate to chiropractic care, and traditional acupuncturists spend much of their time treating such “classic” conditions.

The most common conditions treated by acupuncture which parallel chiropractic are: arthritis; low back pain; premenstrual tension; and repetitive strain injury. Acupuncture has also proved to relax the patient initially, thus making a chiropractic manipulation easier and possibly more beneficial.
