- BACKGROUND: The present study was designed to evaluate if electro-acupuncture (EA) could affect oligo-/anovulation and related endocrine and neuroendocrine parameters in women with polycystic ovary syndrome (PCOS). METHODS: Twenty-four women (between the ages of 24 and 40 years) with PCOS and oligo-/amenorrhea were included in this non-randomized, longitudinal, prospective study. The study period was defined as the period extending from 3 months before the first EA treatment, to 3 months after the last EA treatment (10-14 treatments), in total 8-9 months. The menstrual and ovulation patterns were confirmed by recording of vaginal bleedings and by daily registrations of the basal body temperature (BBT). Blood samples were collected within a week before the first EA, within a week after the last EA and 3 months after EA. RESULTS: Nine women (38%) experienced a good effect. They displayed a mean of 0.66 ovulations/woman and month in the period during and after the EA period compared to a mean of 0.15 before the EA period (p=0.004). Before EA, women with a good effect had a significantly lower body-mass index (BMI) (p<0.001), waist-to-hip circumference ratio (WHR) (p=0.0058), serum testosterone concentration (p=0.0098), serum testosterone/sex hormone binding globulin (SHBG) ratio (p=0.011) and serum basal insulin concentration (p=0.0054), and a significantly higher concentration of serum SHBG (p=0.040) than did those women with no effect. CONCLUSION: Repeated EA treatments induce regular ovulations in more than one third of the women with PCOS. The group of women with good effect had a less androgenic hormonal profile before treatment and a less pronounced metabolic disturbance compared with the group with no effect. For this selected group EA offers an alternative to pharmacological ovulation induction.

- OBJECTIVE: to investigate the attendance rate at childbirth and parenthood education classes during pregnancy in a national Swedish sample and describe the characteristics of women who did not attend. DESIGN: a cohort study utilising a postal questionnaire in early pregnancy and at 2 months after birth. SETTING: women were recruited from 97% of all antenatal clinics in Sweden at their first 'booking' visit during three different weeks spread over 1 year in 1999-2000. PARTICIPANTS: 2546 women, who were 77% of those who consented to participate in the study and 55% of all women eligible for the study. MEASUREMENT AND FINDINGS: most primiparous women (93%) attended classes and the majority of the multiparae (81%) did not. Having a native language other than Swedish was associated with non-attendance in both primiparae and multiparae (OR 2.7, 95% CI 1.3-5.4; OR 2.1, 95% CI 1.4-3.1). In addition, the following factors were associated with non-attendance in the primiparae: unemployment (OR 2.0, 95% CI 1.1-3.8), smoking during pregnancy (OR 2.7, 95% CI 1.2-5.8), having considered abortion (OR 4.3, 95% CI 1.2-16.1), and having had few antenatal check-ups (OR 2.0, 95% CI 1.1-3.7). The following factors were associated with non-attendance in the multiparae: age older than 35 years (OR 1.6, 95% CI 1.1-2.3), low level of education (OR 3.6, 95% CI 2.3-5.7), and pregnancy unplanned but welcome (OR 1.5, 95% CI 1.1-2.0), having had counselling because of fear of childbirth (OR 1.6, 95% CI 1.1-2.4), and expressing a need of such counselling (OR 1.9, 95% CI 1.1-3.1). KEY CONCLUSIONS: the childbirth and parenthood education programme reached the majority of pregnant women, and that non-attendees were more disadvantaged in terms of socio-demographic background and feelings about the approaching birth. These women should be given special attention during the antenatal check-ups so that childbirth and parenthood education could be adapted to their specific needs.

- OBJECTIVE:To investigate the ability of human uterine myocytes to grow under anaerobic conditions for a prolonged time period.METHODS:Cells were isolated from fundal myometrium and cultured until subconfluency. The cell type was confirmed by immunostaining for the smooth muscle cell-specific cytoskeletal proteins alpha-actin and desmin. Some cells were further cultured under aerobic conditions and others under anaerobic conditions. Cells were harvested after 0, 4 and 8 days in culture and analyzed for their content of adenylates.RESULTS:Immunostaining revealed that all three preparations contained almost only smooth muscle cells. Energy charge of the myocytes was 0.88 on average at the beginning of the culture experiment. A moderate decrease was noted on day 4 for myocytes grown under both aerobic and anaerobic conditions and no further decrease was noted between days 4 and 8. Morphologically the cells retained their normal appearance and they seemed healthy for at least 8 days in culture under both aerobic and anaerobic conditions.CONCLUSIONS:The results of this study suggest that human myometrial cells can survive for an extended period of time under in vitro conditions regardless of oxygen availability for energy metabolism. This means that anaerobic energy metabolism is enough to sustain vital processes during that period of time.

- The aims of the present study were to investigate corticotropin-releasing factor (CRF) concentrations in the brain, the adrenal glands, and the ovaries in rats with estradiol valerate (EV) induced polycystic ovaries (PCO). The effect of 12 electro-acupuncture (EA) treatments on CRF concentrations was also investigated. The CRF concentrations in the median eminence (ME) were significantly increased in rats with PCO (both the PCO control group and the PCO group receiving EA) compared with the healthy control group (veichle control group), indicating increased activity in the hypothalamus-pituitary axis. The CRF concentrations in the ovaries were significantly reduced in the PCO group receiving EA compared with the PCO control group. Also, there was a decrease in comparison withthe healthy control group but the decrease was not as significant. This finding indicates that repeated EA treatments change the neuroendocrinological state in the ovaries, which may play an important role in reproductive failure.

- Despite extensive research on the pathogenesis of polycystic ovary syndrome (PCOS), there is still disagreement on the underlying mechanisms. The rat model for experimentally induced polycystic ovaries (PCO)-produced by a single injection of estradiol valerate-has similarities with human PCOS, and both are associated with hyperactivity in the sympathetic nervous system. Nerve growth factor (NGF) is known to serve as a neurotrophin for both the sympathetic and the sensory nervous systems and to enhance the activity of catecholaminergic and possibly other neuron types. Electro-acupuncture (EA) is known to reduce hyperactivity in the sympathetic nervous system. For these reasons, the model was used in the present study to investigate the effects of EA (12 treatments, approximately 25 min each, over 30 days) by analyzing NGF in the central nervous system and the endocrine organs, including the ovaries. The main findings in the present study were first, that significantly higher concentrations of NGF were found in the ovaries and the adrenal glands in the rats in the PCO model than in the control rats that were only injected with the vehicle (oil or NaCl). Second, that repeated EA treatments in PCO rats resulted in concentrations of NGF in the ovaries that were significantly lower than those in non-EA-treated PCO rats but were within a normal range that did not differ from those in the untreated oil and NaCl control groups. The results in the present study provide support for the theory that EA inhibits hyperactivity in the sympathetic nervous system.

- AimTo investigate the association between length of postpartum stay and duration of breastfeeding and breastfeeding problems, with special focus on early hospital discharge. Methods: Swedish-speaking women were recruited from all antenatal clinics in Sweden during 3 wk evenly spread over 1 y in 1999 to 2000. In total, 3293 women (71% of those who were eligible) consented to participate in the study. Data were collected by questionnaires in early pregnancy, 2 mo and 1 y postpartum, and from the Swedish Medical Birth Register. For the purpose of this study, only data from the 2709 women (82%) who filled in the question about length of stay in the 2-mo questionnaire were analysed. Women were divided into six groups according to length of postpartum stay (day 1: < 24h to day 6: ± 120h). Results: The median duration of any breastfeeding was 7 mo in women discharged on day 1, and 8 mo in women discharged on any of the following days; a non-significant difference (p= 0.66). Besides hospital policies regarding length of stay (residential area) and number of domiciliary visits, early discharge was associated with the following maternal characteristics, which could be divided into three categories: (1) older, multipara, many children; (2) positive experience of the first breastfeeding after birth; (3) low education, economic problems, smoking, lack of support from partner. Late discharge was associated with operative delivery, preterm birth and low infant birthweight. When these factors were controlled for by Cox regression analysis, no statistical differences were found between the six groups in the relative risk of discontinuing to breastfeed. Breastfeeding problems, such as engorgement and mastitis, did not differ, but women discharged on day 6 or later had fewer problems with sore or cracked nipples during the first week and more problems 4–8 wk postpartum.ConclusionMaternal characteristics may be more important predictors of the duration of breastfeeding than length of stay in hospital after the birth. The effect of domiciliary support needs further research.
