Collagen Peptides Improve Bone Density in Postmenopausal Women

To improve bone density in postmenopausal women, calcium and vitamin D are important alongside collagen peptides. Bone density in postmenopausal women can be improved with a 12-month daily oral administration of 5g of specific collagen peptides, say researchers in Germany. A total of 131 women aged 46 to 80, were randomised to receive either a daily dose of collagen peptide or a placebo powder. The substances were dissolved in a glass of water and taken before breakfast. All subjects were given information on the importance of regular physical activity and balanced nutrition. They were also encouraged to take a daily dose of calcium (500-800mg) and vitamin D (400-800iu). A DEXA scan of the lumbar spine at L1-L4, and at the neck of the thigh bone, was performed at baseline and after 12 months. Blood levels of bone markers were also monitored.

In the 102 women who completed the study, there were significant improvements in bone mineral density in the peptide group: 3% in the spine and 7% in the femoral neck. In the placebo group, bone density actually fell by around 1%. Similarly, blood levels of bone markers suggested increased bone formation in the treatment group, and increased bone degradation in the placebo group.

The authors say there is insufficient knowledge about which type of collagen peptides (marine, porcine, bovine etc) exerts the most favorable effect. The manufacturing process could also influence the properties of collagen peptides and thus their effectiveness. More human studies and additional data on optimal timing and dosage are needed.

Acupuncture after Laparoscopy Hastens Discharge Time

Acupuncture after laparoscopy hastens discharge time. Acupuncture after laparoscopy reduces the time to discharge for patients who have undergone the procedure plus anaesthetic. Research teams based in Germany and Switzerland, randomly allocated 75 women to receive either acupuncture with standard anaesthetics, acupressure, or standard anaesthetics alone.

In the acupuncture group, median time to discharge was 35% shorter than in the standard anaesthetics alone group. It was also shorter than in the acupressure group. Median time to removal of the endotracheal tube was 7 minutes shorter in the acupuncture and acupressure groups, compared with the standard anaesthetics alone group. The researchers point out that modern surgery management requires increasing operating theatre turnover and more ambulatory procedures. Post-anaesthetic recovery therefore needs to be optimised, and further work should be encouraged to consider a role for acupuncture.

Acupressure for Nausea after Surgery

Acupressure for nausea and vomiting after surgery. A team of researchers in Turkey looking at the possibilities of acupressure for nausea and vomiting after gynaecological surgery, have concluded it represents a viable alternative to drugs. They randomised 97 women to receive either standard drugs during and after surgery, or to receive acupressure to the point Neiguan using a wristband. The latter was left in place during the first 12 hours following surgery.

Acupressure was associated with preventing vomiting and a significant reduction in nausea. Patients’ general comfort level also improved. The study authors say that because of its effectiveness and feasibility, wristband acupressure is a great alternative to pharmacologic methods in the gynaecological surgery population.

Acupuncture for Menstrual Pain

Acupuncture in Exeter: acupuncture for menstrual pain. A systematic review by Korean authors looking at acupuncture for menstrual pain shows it is an effective intervention. The review examined 60 randomised controlled trials covering over 3000 patients; 49 trials were subject to meta-analysis. The studies compared acupuncture to no treatment, placebo or medication.

Compared with both no treatment and nonsteroidal anti-inflammatory drugs, acupuncture was more effective at reducing menstrual pain. The benefits of acupuncture were also maintained during short-term follow-up.

Acupuncture and PMS Symptoms

Acupuncture and PMS symptoms. A Cochrane Database systematic review by Australian authors, has concluded that acupuncture and acupressure may improve both physical and psychological symptoms of PMS. Five trial results, covering 277 women, were analysed. The results suggest acupuncture can improve overall mood and physical symptoms, compared with sham acupuncture. Quality of evidence was limited by small sample sizes.
