How do reproductive history and anthropometry in midlife relate to later risk of pelvic organ prolapse? A prospective cohort study.

INTRODUCTION AND HYPOTHESIS: The objective was to examine the association between reproductive and anthropometric factors and later risk of pelvic organ prolapse (POP). METHODS: We carried out a prospective cohort study including 11,114 female nurses > 44 years from the Danish Nurse Cohort. In 1993, the study population was recruited through the Danish Nurse Organization and self-reported data on age, height, weight, age at menarche, age at first birth and number of childbirths were obtained. POP diagnosis was obtained from the National Patient Registry. Risk of POP was estimated using COX regression and presented as hazard ratios (HR) with 95% confidence intervals (CI). RESULTS: Overall, 10% of the women received a diagnosis of POP within a median follow-up of 22 years. A 4% increase in risk of POP was seen for each increasing BMI (kg/m2) unit at baseline. Compared to women of normal weight, higher risks of POP were seen in overweight (HR 1.18: 1.02-1.36) and obese women (HR 1.33: 1.02-1.74), while underweight had a lower risk (HR 0.51: 0.27-0.95). Compared to women with one childbirth, women with no childbirths had a reduced risk of 57% while increased risks of 46%, 78% and 137% were observed in women with two, three and four childbirths. Women with menarche before the age of 12 tended to have a higher risk of POP as did women who were 30-33 years at their first childbirth. CONCLUSIONS: POP is a common health problem in women, and BMI and number of childbirths are strong predictors.

Decreased gum bleeding and reduced gingivitis by the probiotic Lactobacillus reuteri.

The primary aim of this study was to assess if the probiotic Lactobacillus reuteri could be effective in the treatment of gingivitis and further to evaluate the influence of the probiotic on plaque and the lactobacilli population in the saliva. A randomised, placebo-controlled, double blind study was performed over 2 weeks. Fifty-nine patients with moderate to severe gingivitis were included and given one of two different Lactobacillus reuteri formulations (LR-1 or LR-2) at a dose of 2 x 10(8) CFU per day, or a corresponding placebo. At baseline (day 0) gingival index and plaque index were measured on two surfaces and saliva for lactobacilli determination was collected. The patients were instructed how to brush and floss efficiently and study treatment was started.The patients returned on day 14 for final assessment of gingivitis and plaque and saliva was collected. 20 patients were randomised to LR-1, 21 to LR-2 and 18 to placebo. Gingival index fell significantly in all 3 groups (p < 0.0001). LR-1, but not LR-2 improved more than placebo (p < 0.0001). Plaque index fell significantly in LR-1 (p < 0.05) and in LR-2 (p < 0.01) between day o and day 14 but there was no significant change in the placebo group. At day 14, 65% of the patients in LR-1 were colonised with Lactobacillus reuteri and 95% in the LR-2 group. Lactobacillus reuteri was efficacious in reducing both gingivitis and plaque in patients with moderate to severe gingivitis.
