Introduction: Increased BMI has been identified as a risk factor for most pregnancy complications, but the underlying metabolic factors mediating the detrimental effects of BMI are largely unknown. We aimed to compare metabolic profiles in overweight/obese women (body mass index [BMI] ≥ 25 kg/m 2 ) and normal weight/underweight women (BMI < 25 kg/m 2 ) across gestation. We also explored how gestational weight gain (GWG) affected maternal metabolic profiles., Material and Methods: Exploratory nested case-control study based on a prospective longitudinal cohort of women who were healthy prior to pregnancy and gave birth at Oslo University Hospital from 2002 to 2008. The sample consisted of 48 women who were overweight/obese and 59 normal-weight/underweight women. Plasma samples from four time points in pregnancy (weeks 14-16, 22-24, 30-32 and 36-38) were analyzed by nuclear magnetic resonance spectroscopy and 91 metabolites were measured. Linear regression models were fitted for each of the metabolites at each time point., Results: Overweight or obese women had higher levels of lipids in very-low-density lipoprotein (VLDL), total triglycerides, triglycerides in VLDL, total fatty acids, monounsaturated fatty acids, saturated fatty acids, leucine, valine, and total branched-chain amino acids in pregnancy weeks 14-16 compared to underweight and normal-weight women. Docosahexaenoic acid and degree of unsaturation were significantly lower in overweight/obese women in pregnancy weeks 36-38. In addition, overweight or obese women had higher particle concentration of XXL-VLDL and glycoprotein acetyls (GlycA) at weeks 14-16 and 30-32. GWG did not seem to affect the metabolic profile, regardless of BMI group when BMI was treated as a dichotomous variable, ≥25 kg/m 2 (yes/no)., Conclusions: Overweight or obese women had smaller pregnancy-related metabolic alterations than normal-weight/underweight women. There was a trend toward higher triglyceride and VLDL particle concentration in overweight/obese women. As this was a hypothesis-generating study, the similarities with late-onset pre-eclampsia warrant further investigation. The unfavorable development of fatty acid composition in overweight/obese women, with possible implication for the offspring, should also be studied further in the future., (© 2023 The Authors.

Introduction: Preeclampsia is associated with maternal metabolic disturbances, but longitudinal studies with comprehensive metabolic profiling are lacking. We aimed to determine metabolic profiles across gestation in women who developed preeclampsia compared with women with healthy pregnancies. We also explored the respective effects of body mass index (BMI) and preeclampsia on various metabolic measures., Material and Methods: We measured 91 metabolites by high-throughput nuclear magnetic resonance spectroscopy at four time points (visits) during pregnancy (weeks 14-16, 22-24, 30-32 and 36-38). Samples were taken from a Norwegian pregnancy cohort. We fitted a linear regression model for each metabolic measure to compare women who developed preeclampsia (n = 38) and healthy controls (n = 70)., Results: Among women who developed preeclampsia, 92% gave birth after 34 weeks of gestation. Compared to women with healthy pregnancies, women who developed preeclampsia had higher levels of several lipid-related metabolites at visit 1, whereas fewer differences were observed at visit 2. At visit 3, the pattern from visit 1 reappeared. At visit 4 the differences were larger in most subgroups of very-low-density lipoprotein particles, the smallest high-density lipoprotein, total lipids and triglycerides. Total fatty acids were also increased, of which monounsaturated fatty acids and saturated fatty acids showed more pronounced differences. Concentration of glycine tended to be lower in pregnancies with preeclampsia until visit 3, although this was not significant after correction for multiple testing. After adjustment for age, BMI, parity and gestational weight gain, all significant differences were attenuated at visits 1 and 2. The estimates were less affected by adjustment at visits 3 and 4., Conclusions: In early pregnancy, the metabolic differences between preeclamptic and healthy pregnancies were primarily driven by maternal BMI, probably representing the women's pre-pregnancy metabolic status. In early third trimester, several weeks before clinical manifestation, the differences were less influenced by BMI, indicating preeclampsia-specific changes. Near term, women with preeclampsia developed an atherogenic metabolic profile, including elevated total lipids, very-low-density lipoprotein, triglycerides, and total fatty acids., (© 2023 The Authors.

Background: The aim of this study was to evaluate treatment efficacy and patient compliance in women with an early miscarriage managed expectantly in routine clinical practice., Methods: During 1995-98, 263 consecutive women who sought medical attention for an ongoing or incomplete miscarriage (gestational length <99 days), and who were circulatory stable and had a gestational residue measuring 15-50 mm (anterio-posterior, A-P diameter) on ultrasound examination were invited to participate in this study. Hemoglobin (Hb), C-reactive protein (CRP), human chorionic gonadotrophin (hCG), progesterone and Rh-factor were analyzed and a questionnaire regarding the pregnancy, duration of genital bleeding and number of days of absenteeism was completed on admission and after 1 and 4 weeks., Results: Expectant management was considered to be complete (vaginal ultrasound, gestational residue <15 mm after 1 week) in 83%. The patients who were managed successfully by expectant management had a smaller gestational residue (p = 0.026) and a lower mean serum progesterone level (p = 0.025) on referral than in the group of women with failed expectant management. A gynecologic infection was diagnosed in seven cases (3%) and five of the infections were in the group of women who underwent dilatation and curettage. No patient required a blood transfusion. The mean number of days of absenteeism was 3.2 days. There were no differences in Hb levels before or after treatment, number of bleeding days or absenteeism between the groups., Conclusions: Expectant management of clinically stable patients with symptoms of early miscarriage is safe, efficient and well tolerated.

Background: Bacterial vaginosis (BV) and intermediate flora is known risk-factor for postoperative infection after surgical termination of pregnancy. Vaginal application of 2% clindamycin cream is an efficacious treatment for BV, but it is not known whether preoperative administration of clindamycin cream might reduce the signs of post-abortion infection after surgical termination of pregnancy., Aim: To evaluate whether preoperative treatment with clindamycin cream might reduce the signs of post-abortion infection after legal abortion., Design: Prospective, double-blinded, placebo-controlled, multicenter study., Material and Methods: Consecutive women attending for surgical termination prior to 11+4 gestational weeks were approached. We randomized participants to preoperative vaginal treatment with 2% clindamycin cream or placebo cream in a double-blinded fashion. At all visits vaginal smears were air dried on microscopy slides to be stored. The rate of postoperative pelvic infection according to our definition was the main outcome variable, the cure rates of BV and of intermediate flora were secondary outcome variables., Results: Of 1655 enrolled women, 1102 were evaluable for analyses. Fifty-eight women developed signs of post-abortion infection. Preoperative treatment with clindamycin cream significantly (RR: 4.2, 95% C.I. 1.2-15.9) reduced the risk of post-abortion infection among women with abnormal vaginal flora (BV and intermediate flora). Treatment with clindamycin cream in women with normal lactobacilli flora did not demonstrate any difference compared to the non-treatment group., Conclusion: Preoperative treatment for at least three days with clindamycin cream significantly reduced the risk for developing signs of post-abortion infection only among women with preoperative abnormal vaginal flora (BV and intermediate flora).

Background: In our studies on women with bacterial vaginosis (BV) in early pregnancy a strong association has been found between BV and the levels of endotoxin or interleukin-1alpha (IL-1alpha) in the lower genital tract. In the present study we investigated if an association could be found between BV and other cytokines (IL-1beta, IL-6, tumor necrosis factor alpha, TNF) or fetal fibronectin (FFN). The cytokine-inducing capacity of endotoxins present in the cervical mucus was explored in a monocytic cell assay., Methods: Cervical mucus or cervicovaginal fluid was collected from women with (BV) and without BV (nonBV) attending a family planning unit for first trimester abortion. The concentrations of IL-1beta, IL-6, TNF and FFN were determined by quantitative enzyme immunoassays. TNF was determined in 63 women (BV, n=25) out of whom 37 (BV, n=11) were analyzed for IL-1beta and the remaining 26 for IL-6 (BV, n=14). FFN was determined in another 36 women (BV, n= 19). The cytokine-inducing capacity of endotoxin-containing cervical mucus and purified endotoxin of Prevotella bivia were studied by an in vitro cell assay using a human monocytic cell line (THP-1)., Results: IL-lbeta and IL-6 were found in almost all women. The levels of IL-1beta, but not IL-6, TNF or FFN, were significantly increased in women with BV compared with the nonBV women (p<0.05). Purified endotoxin from P. bivia, and cervical mucus from BV women containing high levels of endotoxin were able to induce a cytokine response (IL-6) in monocytic cells in vitro., Conclusion: BV is associated with increased levels of IL-1beta in the lower genital tract of pregnant women in the first trimester. The ability of BV-associated endotoxins to induce cytokine production in monocytic cells may partly explain the increased IL-1beta levels.

Background: The purpose was to determine the prognostic value of interleukin (IL) 1-alpha, IL-6 and IL-8 in cervico/vaginal secretion for preterm birth (<37 weeks of gestation) in twin pregnancies., Methods: The study included screening of 121 women with twin pregnancies with sampling at 24, 26, 28, 30, 32 and 34 weeks of gestation. IL-1alpha, IL-6 and IL-8 was analyzed with ELISA immunoassays. The detection limit was 30 pg/mL for IL-1 and IL-8 and 40 pg/mL for IL-6. Vaginal fluid was smeared and dried for later evaluation of bacterial vaginosis (presence of clue cells)., Results: Spontaneous preterm birth occurred in 36 women and 65 women were delivered at term. IL-8 was significantly higher (p=0.03) in samples from women delivered preterm (median 3.72 ng/g mucus, range <0.07-220.00) compared with samples from women delivered at term (median 3.03 ng/g mucus, range <0.08-378.60). At 28 weeks of gestation, IL-8 (cut off 1.75 ng/g mucus) was associated with preterm delivery (relative risk 2.2, CI 95% 1.1-4.5) with a sensitivity, specificity, positive and negative predictive value of 78.8, 45.8, 44.8 and 79.4%, respectively. The levels of IL-1alpha and IL-6 were not significantly associated with preterm birth. Bacterial vaginosis was found in 47/541 (8.7%) samples analyzed. The levels of IL-1alpha and IL-8 were significantly higher in samples positive for bacterial vaginosis than in negative samples (p<0.0001 and p<0.01, respectively). There was no significant association between the level of IL-6 and bacterial vaginosis., Conclusions: IL-8, but not IL-1alpha and IL-6, was associated with preterm delivery but the relationship was too weak to be of predictive value for preterm birth in twin pregnancies. IL-1alpha and IL-8, but not IL-6, were associated with bacterial vaginosis.

Background: An increased use of prophylactic antibiotics to avoid postoperative infections in women undergoing hysterectomy has been observed in Sweden. This investigation was performed a) to study the infection rate to enable future evaluation of the effect of prophylactic antibiotic regimens and b) to identify subgroups suitable for intervention., Method: A prospective study comprising all women undergoing pelvic surgery with hysterectomy during a two month period at forty-two Departments of Obstetrics and Gynecology in Sweden. Relevant information regarding the surgical procedure and the postoperative course was included in a standardized form at discharge from hospital and at a follow-up visit 4 to 6 weeks after surgery., Results: Of the 1060 women included in the study, 23% developed postoperative infections: 9.4% had wound-, cuff-, and/or deep infections, 13% urinary tract infections, and 4% other infections unrelated to the surgical site. Only half of the wound/cuff-/deep infections were diagnosed before discharge from the hospital. Wertheim-Meigs procedures, bleedings per-operatively exceeding 1000 ml, and presence of bacterial vaginosis (BV) were associated with an increased risk of postoperative infections. Among women undergoing abdominal hysterectomy for benign reasons, (n = 159), wound-cuff/deep infection was significantly associated with preoperative BV, i.e. 7 of 28 (25%) vs. 11 of 131 (8%), respectively (relative risk = 3.0, p = 0.01). Infection was associated with prolonged postoperative hospital stay. Antibiotics were given pre- or postoperatively to 236 (22%) of the 1060 women. Reduction in the postoperative infection rate was seen among women undergoing vaginal hysterectomy who were given pre- or postoperative antibiotics., Conclusion: The postoperative infection rate after hysterectomy was clinically significant in this population. Wertheim-Meigs procedures, peroperative bleeding > 1000 ml and BV were identified as risk factors for postoperative infections after hysterectomy.

Background: To study the effectiveness of three different cervical ripening agents in terms of dilatation ability and patient discomfort in connection with legal first trimester abortion., Methods: Three randomized trials among unselected nulliparous women were performed 1: hygroscopic tent versus gemeprost, 2: misoprostol versus gemeprost and 3: misoprostol administered orally 17 versus 10 hours before vacuum curettage was performed., Main Outcomes: Dilatation ability, frequent gastrointestinal side effects, severe pain (patients' perception)., Results: In Trial 1, there was a tendency of a greater dilatation ability using the hygroscopic tent, while the experience of pain was a greater problem with gemeprost. In Trials 2 and 3, there were no significant differences in the dilatation abilities or gastrointestinal patient discomfort. There was a tendency towards a higher demand for narcotic analgesics in patients treated with gemeprost compared with all other groups., Conclusions: Gemeprost and misoprostol showed almost identical ability to dilate and caused patient-experienced discomfort to the same degree. The use of misoprostol may be preferred as it has the advantage of being both less expensive and easier to administer.

In order to define the relationship between various criteria of female lower genital tract inflammation, we examined wet smears, cervical smears and biopsies from 131 patients. The presence of clue cells in rehydrated dry smears showed a positive correlation to the presence of clue cells in Papanicolaou stained smears, and to some extent with cytological evidence of inflammation (Kappa 0.48). Cytological inflammatory findings correlated well with the presence of clue cells in rehydrated dry smears, but signs of inflammation diagnosed by histopathology did not correspond to findings in cytological smears, probably because these methods reveal inflammation at different sites.

Objective: To compare a new regimen for second trimester abortion using Dilapan and vaginal gemeprost suppositories with extra-amniotic Rivanol instillation and oxytocin i.v. immediately or 16 h after instillation., Methods: A prospective study was performed in 153 women to analyze the induction-abortion interval, the use of analgesics and the complication rate. Wilcoxon's rank sum test was used for statistical evaluation., Results: The mean induction-abortion interval was significantly shorter in the Dilapan-gemeprost-treated women than in the immediate or 16-h Rivanol-oxytocin-treated women, 12.5 vs. 23.3 and 26.8 h, respectively. The 24-h cumulative abortion rate was 91% in the former group vs. 49% and 61%, respectively. The use of analgesics was less frequent among the Dilapan-gemeprost-treated women, whereas the complication rate did not differ., Conclusions: The Dilapan-gemeprost treatment was advantageous with respect to a shorter induction-abortion interval and ease of handling. However a minority of women do not respond to this treatment and it is therefore necessary to employ alternative methods to complete the abortion in these cases.

In a prospective study of 107 women, bacterial vaginosis was clinically diagnosed in 34 women. Compared with clinical diagnosis of bacterial vaginosis, detection of clue cells in Papanicolaou stained vaginal smears showed a sensitivity of 88.2%, a specificity of 98.6%, a positive predictive value of 96.8% and a negative predictive value of 94.7%. The corresponding values for detection of bacterial vaginosis in Gram stained smears compared with the clinical diagnosis were 100%, 97.3%, 94.4% and 100%, respectively. Compared with clue cells in wet smears, identification of clue cells in Papanicolaou stained vaginal smears showed a Kappa index of 0.87 and compared with Gram stain criteria a Kappa index of 0.94. The correlation between Gram stain and Papanicolaou stained vaginal smears showed a Kappa index of 0.89. In contrast to the results of earlier investigators our studies indicate that the demonstration of clue cells in Papanicolaou stained vaginal smears correlate reasonably well with the conventional clinical criteria. However, the Gram stain method may be more reliable than the Papanicolaou method.

Bacterial vaginosis (BV) represents a disturbance in the vaginal microflora with a massive overgrowth of predominantly anaerobic bacteria resulting in a disagreeable vaginal discharge. The syndrome of BV has been described in the medical literature since the turn of the century. BV has been considered as an unpleasant but essentially harmleis disturbance of the vaginal micro-flora. However, during the last decade a number of clinical reports have appeared indicating that women with BV run an increased relative risk of postabortal pelvic inflammatory disease, preterm labor, premature rupture of the membranes and post par-tum and post-Cesarean endometritis. The present study was carried out., (1994 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.)

Methods: In an attempt to investigate an association between the finding of clue cells in Papanicolaou-stained (PAP) smears and cervical intraepithelial neoplasia (CIN), a total of 6150 smears from 1976 were re-investigated., Results: Clue cells representing bacterial vaginosis were present in 10% of the PAP-smears. CIN II and III alone, as well as all CIN cases, were more common in women with bacterial vaginosis (p < 0.001). Histologically CIN III/carcinoma in situ was found in nine patients with and in 16 patients without bacterial vaginosis. The relative risk of having CIN III/carcinoma in situ if the women had bacterial vaginosis was 5.0 with 95% confidence interval of 2.2-11.6., Conclusions: The possibility exists that bacterial vaginosis is in some way associated with the development of cervical intraepithelial neoplasia, i.e. as a cofactor to human papilloma virus. Therefore, bacterial vaginosis must be taken in consideration in future studies on CIN.

Bacterial vaginosis (BV) has been considered by many investigators to be a risk factor for preterm labor. We have followed vaginal pH and the persistence of clue cells in Papanicolaou stained smears in 119 pregnant women during the course of pregnancy. Of 19 patients with clue cells in their smears during the first trimester, 11 (58%) still had clue cells at the second visit during the third trimester. Of the 100 patients without clue cells during their first trimester, none exhibited clue cells during the third trimester. If the persistence of clue cells is truly a risk factor for adverse pregnancy outcome, screening in the first trimester would identify a risk group of 15%. This risk group diminishes to 9% at the time of the third trimester. Vaginal pH > 4.5 had a recovery sensitivity of 76% and specificity of 83%. If clue cells can be considered as the identifying standard for bacterial vaginosis, the sensitivity and specificity of pH is 89% and 94%, respectively. The establishment of the diagnosis of BV during pregnancy and, in some cases, the treatment of the condition may be important as routine procedures in the antenatal center.

Many different criteria and profiles have been suggested for the possible cause of regret and requests for reversal after tubal sterilization. Evaluation of data obtained from 2253 women who had undergone tubal sterilization showed a strong correlation between regrets and youthful age and to changes in marital situation. Previously demonstrated risk factors, such as sterilization in connection with abortion or labor were not related to regret in this study material.

Women attending our Department for a first-trimester abortion were examined for the presence of Mobiluncus species. C. trachomatis or clue cells in vaginal discharge in an attempt to identify risk groups for development of pelvic inflammatory disease (PID) after first-trimester abortion. A correlation was found between the presence of Mobiluncus and clue cells in vaginal discharge and the incidence of PID after first-trimester abortions. These women were also older than those in whom C. trachomatis was identified. Our study indicates that screening for C. trachomatis and clue cells in vaginal discharge will identify two different risk groups for developing PID after first-trimester abortion.
