Antenatal fear of childbirth and its association with subsequent caesarean section and experience of childbirth.
OBJECTIVE: To investigate the prevalence of fear of childbirth in a nationwide sample and its association with subsequent rates of caesarean section and overall experience of childbirth. DESIGN: A prospective study using between-group comparisons. SETTING: About 600 antenatal clinics in Sweden. SAMPLE: A total of 2,662 women recruited at their first visit to an antenatal clinic during three predetermined weeks spread over 1 year. METHODS: Postal questionnaires at 16 weeks of gestation (mean) and 2 months postpartum. Women with fear of childbirth, defined as 'very negative' feelings when thinking about the delivery in second trimester and/or having undergone counselling because of fear of childbirth later in pregnancy, were compared with those in the reference group without these characteristics. MAIN OUTCOME MEASURES: Elective and emergency caesarean section and overall childbirth experience. RESULTS: In total 97 women (3.6%) had very negative feelings and about half of them subsequently underwent counselling. In addition, 193 women (7.2%) who initially had more positive feelings underwent counselling later in pregnancy. In women who underwent counselling, fear of childbirth was associated with a three to six times higher rate of elective caesarean sections but not with higher rates of emergency caesarean section or negative childbirth experience. Very negative feelings without counselling were not associated with an increased caesarean section rate but were associated with a negative birth experience. CONCLUSIONS: At least 10% of pregnant women in Sweden suffer from fear of childbirth. Fear of childbirth in combination with counselling may increase the rate of elective caesarean sections, whereas fear without treatment may have a negative impact on the subsequent experience of childbirth.

Duration of breastfeeding and breastfeeding problems in relation to length of postpartum stay: a longitudinal cohort study of a national Swedish sample.
AIM: To 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: < 24 h to day 6: > or = 120 h). 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. CONCLUSION: Maternal 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.

Early discharge of preterm infants followed by domiciliary nursing care: parents' anxiety, assessment of infant health and breastfeeding.
UNLABELLED: The aim of this study was to evaluate the effect of early discharge of preterm infants, followed by domiciliary nursing care, on the parents' anxiety, their assessment of infant health and breastfeeding. Seventy-five families including 88 preterm infants who were physiologically stable but in need of further special care, such as gavage feeding, were allocated to an early discharge group (EDG) that was offered home visits (n = 40), or to a control group offered standard neonatal care (CG) (n = 35). Seventy families (37 in the EDG and 33 in the CG) completed the study to the 1-y follow-up. Data were collected by means of questionnaires on three occasions: in the EDG, at hospital discharge, on completion of the domiciliary care programme and after 1 y, and in the CG at the corresponding points in time, which were during hospitalization, at hospital discharge and after 1 y. No statistical differences were observed between the groups in emotional well-being, except that mothers in the EDG had a lower level of situational anxiety at the time of hospital discharge compared with CG mothers whose infants remained in hospital. One year after the birth, the EDG mothers said they had felt better prepared to take responsibility for the care of their babies after completion of the domiciliary care programme, in contrast to CG mothers. However, no statistical differences were observed in the recollection of anxiety, confidence in handling the baby and periods of mental imbalance. No statistical difference was observed in breastfeeding rates between the groups. Fathers in the EDG group tended to perceive their babies as being healthier, compared with CG fathers. CONCLUSION: Early discharge of preterm infants followed by domiciliary nursing care did not seem to have any major effect on the parents' anxiety and their assessment of infant health.

Hydrosalpinx and IVF outcome: cumulative results after salpingectomy in a randomized controlled trial.
BACKGROUND: A randomized controlled trial of salpingectomy prior to IVF in patients with hydrosalpinges has been conducted in Scandinavia. The results from the first transfer cycle have been published and clearly demonstrated an improved pregnancy outcome after salpingectomy had been performed in patients with hydrosalpinges large enough to be visible on ultrasound. The present article is aimed at analysing the effect of salpingectomy on cumulative birth rate, including all individual transfer cycles. METHODS AND RESULTS: A total of 186 women underwent 452 cycles. Among the 77 women randomized to no surgical intervention, 24 underwent salpingectomy after one or two failed cycles. Cumulative results were analysed by Cox regression, taking into account the number of cycles per patient and the presence of a salpingectomy after a previous transfer. Salpingectomy implied a significant increase in birth rate (hazard ratio 2.1, 95% CI 1.6-3.6, P = 0.014). Within the subgroup of patients with ultrasound-visible hydrosalpinges, the birth rate was even higher (hazard ratio 3.8, 95% CI 1.5-9.2, P = 0.004). Implantation rate was significantly higher in patients who had undergone salpingectomy (27.2% versus 20.2, P = 0.03) and, in the subgroup of patients with ultrasound-visible hydrosalpinges, the difference was even larger (30.3% versus 17.1%, P = 0.003). CONCLUSIONS: The results of the cumulative cycles strengthen the recommendation for a laparoscopic salpingectomy prior to IVF in patients with ultrasound-visible hydrosalpinges.

Prophylactic salpingectomy does not impair the ovarian response in IVF treatment.
To examine the effect of prophylactic salpingectomy in patients with hydrosalpinges on the ovarian response to stimulation prior to IVF, 26 patients were included in a study in which they acted as their own controls. They were all part of a randomized controlled study, in which they had been randomized to no surgical intervention prior to IVF. After one or two failed cycles, they underwent laparoscopic uni- or bilateral salpingectomy of their diseased tubes. The cycles before and after surgery were compared and the ovarian response was assessed as the dose and duration of gonadotrophins and the number of retrieved and fertilized oocytes. There were no significant differences in any of the measured outcomes. The increasing age between cycles did not influence the ovarian response, assessed by a comparison with two matched control groups from the same original study; 46 patients salpingectomized before IVF and 25 patients without surgery. It is concluded that removal of hydrosalpinx as a prophylactic laparoscopic procedure does not compromise ovarian function.

Team midwife care: maternal and infant outcomes.
The aim of this study was to add additional information on intervention rates and maternal and infant outcomes of team midwife care to previous reports which have suggested this model of care can be associated with a reduction in medical interventions during labour and birth with no statistically significant influence on maternal and infant outcomes. The study was designed as a randomised controlled trial, with 495 women randomised to team midwife care being compared to 505 women randomsed to standard care. The study revealed no statistical differences between team midwife care and standard care in medical interventions, maternal health and infant health. These findings suggest that team midwifery as it is practised in this study is a safe alternative for women.

Randomised controlled trial of midwife led debriefing to reduce maternal depression after operative childbirth.
OBJECTIVE: To assess the effectiveness of a midwife led debriefing session during the postpartum hospital stay in reducing the prevalence of maternal depression at six months postpartum among women giving birth by caesarean section, forceps, or vacuum extraction. DESIGN: Randomised controlled trial. SETTING: Large maternity teaching hospital in Melbourne, Australia. PARTICIPANTS: 1041 women who had given birth by caesarean section (n= 624) or with the use of forceps (n= 353) or vacuum extraction (n= 64). MAIN OUTCOME MEASURES: Maternal depression (score >/=13 on the Edinburgh postnatal depression scale) and overall health status (comparison of mean scores on SF-36 subscales) measured by postal questionnaire at six months postpartum. RESULTS: 917 (88%) of the women recruited responded to the outcome questionnaire. More women allocated to debriefing scored as depressed six months after birth than women allocated to usual postpartum care (81 (17%) v 65 (14%)), although this difference was not significant (odds ratio=1.24, 95% confidence interval 0.87 to 1.77). They were also more likely to report that depression had been a problem for them since the birth, but the difference was not significant (123 (28%) v 94 (22%); odds ratio=1. 37, 1.00 to 1.86). Women allocated to debriefing had poorer health status on seven of the eight SF-36 subscales, although the difference was significant only for role functioning (emotional): mean scores 73.32 v 78.98, t= -2.31, 95% confidence interval -10.48 to -0.84). CONCLUSIONS: Midwife led debriefing after operative birth is ineffective in reducing maternal morbidity at six months postpartum. The possibility that debriefing contributed to emotional health problems for some women cannot be excluded.

Does team midwife care increase satisfaction with antenatal, intrapartum, and postpartum care? A randomized controlled trial.
BACKGROUND: Although policymakers have suggested that improving continuity of midwifery can increase women's satisfaction with care in childbirth, evidence based on randomized controlled trials is lacking. New models of care, such as birth centers and team midwife care, try to increase the continuity of care and caregiver. The objective of this study was to evaluate the effect of a new team midwife care program in the standard clinic and hospital environment on satisfaction with antenatal, intrapartum, and postpartum care in low-risk women in early pregnancy. METHODS: Women at Royal Women's Hospital in Melbourne, Australia, were randomly allocated to team midwife care (n = 495) or standard care (n = 505) at booking in early pregnancy. Doctors attended most women in standard care, and continuity of the caregiver was lacking. Satisfaction was measured by means of a postal questionnaire 2 months after the birth. RESULTS: Team midwife care was associated with increased satisfaction, and the differences between the groups were most noticeable for antenatal care, less noticeable for intrapartum care, and least noticeable for postpartum care. The study found no differences between team midwife care and standard care in medical interventions or in women's emotional well-being 2 months after the birth. CONCLUSION: Conclusions about which components of team midwife care were most important to increased satisfaction with antenatal care were difficult to draw, but data suggest that satisfaction with intrapartum care was related to continuity of the caregiver.

Team midwifery care in a tertiary level obstetric service: a randomized controlled trial.
BACKGROUND: In 1996 a new model of maternity care characterized by continuity of midwifery care from early pregnancy through to the postpartum period was implemented for women attending Monash Medical Centre, a tertiary level obstetric service, in Melbourne, Australia. The objective of this study was to compare the new model of care with standard maternity care. METHODS: In a randomized controlled trial, 1000 women who booked at the antenatal clinic and met the eligibility criteria were randomly allocated to receive continuity of midwifery care (team care) from a group of seven midwives in collaboration with obstetric staff, or care from a variety of midwives and obstetric staff (standard care). The primary outcome measures were procedures in labor, maternal outcomes, neonatal outcomes, and length of hospital stay. RESULTS: Women assigned to the team care group experienced less augmentation of labor, less electronic fetal monitoring, less use of narcotic and epidural analgesia, and fewer episiotomies but more unsutured tears. Team care women stayed in hospital 7 hours less than women in standard care. More babies of standard care mothers were admitted to the special care nurseries for more than 5 days because of preterm birth, and more babies of team care mothers were admitted to the nurseries for more than 5 days with intrauterine growth retardation. No differences occurred in perinatal mortality between the two groups. CONCLUSIONS: Continuity of midwifery care was associated with a reduction in medical procedures in labor and a shorter length of stay without compromising maternal and perinatal safety. Continuity of midwifery care is realistically achievable in a tertiary obstetric referral service.

Effects of electro-acupuncture on nerve growth factor and ovarian morphology in rats with experimentally induced polycystic ovaries.
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.

Effects of electro-acupuncture on anovulation in women with polycystic ovary syndrome.
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.

Experience of labor and birth in 1111 women.
The association between women's overall experience of labor and birth and a range of possible explanatory variables were studied in a group of 1111 women who participated in a birth center trial. Data were collected by a questionnaire in early pregnancy (demographic background, parity, personality traits, and expectations), hospital records (pharmacological pain relief, induction, augmentation of labor, duration of labor, operative delivery, and infant outcome), and a follow-up questionnaire 2 months after the birth (the principal outcome "overall experience of labor and birth," pain, anxiety, freedom in expression, involvement, midwife, and partner support). Logistic regression was conducted by including all variables that were associated with the birth experience when analyzed one by one. In a second regression analysis, only explanatory variables measured independently of the principal outcome were included; that is, only data collected from the pregnancy questionnaire and the hospital records. The first regression analysis identified five explanatory variables: involvement in the birth process (perceived control) and midwife support were associated with a positive experience; anxiety, pain, and having a first baby with a negative experience. Parity remained a significant predictor in the second regression analysis, but the others were replaced by augmentation of labor, cesarean section, instrumental vaginal delivery, and nitrous oxide (Entonox), which were all associated with a negative birth experience.

Early discharge of preterm infants needing limited special care, followed by domiciliary nursing care.
The aim of this study was to evaluate the effect of early discharge, followed by domiciliary nursing care, on infant health and utilization of health services in preterm infants still in need of special care (mainly gavage feeding). In total, 88 infants who were physiologically stable, but in need of further special care such as gavage feeding, were allocated to an early discharge group (EDG = 45 infants) and offered home visits by a nurse backed up by a neonatologist, or to a control group offered standard neonatal care (CG = 43 infants). Infants in the EDG spent 30.6 d (mean) in hospital after birth compared with 46.3 d in the CG (p = 0.003). On average, the domiciliary nurse spent 10.4 h with each family in the EDG, including a median number of 5 home visits, scheduled telephone contact and travelling time. The infants had a mean of 1.7 scheduled visits and 0.4 unscheduled visits to the neonatal ward. The domiciliary nurse received a mean of 0.9 telephone calls from the parents. When the period of domiciliary care in the EDG (post-conceptional age 35.9-38.7 wk) was compared with the corresponding time in hospital in the CG (post-conceptional age 35.6-38.6 wk), no statistical differences were observed in infant health, surgical procedures or medication. However, a reduced incidence of respiratory infections was observed in the EDG (6 versus 16 infants; p = 0.02). Nine infants in the EDG were re-hospitalized. The two groups did not differ in the numbers of rehospitalizations and non-elective contacts with the health services during the first year after discharge. In conclusion, early discharge of preterm infants still requiring special care, followed by domiciliary nursing care, was associated neither with an increased utilization of health services after discharge, nor with infant morbidity after discharge. More information on safety is needed before widespread early discharge can be advocated.

A prospective randomized study of electro-acupuncture versus alfentanil as anaesthesia during oocyte aspiration in in-vitro fertilization.
The aim of the present study was to evaluate the anaesthetic effect during oocyte aspiration of a paracervical block (PCB) in combination with either electro-acupuncture (EA) or intravenous alfentanil. In all, 150 women undergoing in-vitro fertilization (IVF) and embryo transfer were randomized to receive either EA plus PCB or alfentanil plus PCB. Visual analogue scales (VAS) were used to evaluate subjective experiences during oocyte aspiration, and IVF outcome parameters were recorded. No differences in pain directly related to oocyte aspiration, adequacy of anaesthesia during oocyte aspiration, abdominal pain, or degree of nausea were found between the two groups in the VAS ratings. Before oocyte aspiration, the level of stress was significantly higher in the EA group than in the alfentanil group (P < 0.05), and the EA group experienced discomfort for a significantly longer period during oocyte aspiration (P < 0. 01). Compared with the alfentanil group, the EA group had a significantly higher implantation rate (P < 0.05), pregnancy rate (P < 0.05), and take home baby rate (P < 0.05) per embryo transfer. In conclusion, EA has been shown to be as good an anaesthetic method as alfentanil during oocyte aspiration, and we suggest that EA may be a good alternative to conventional anaesthesia during oocyte aspiration.
