Patient's preference for sacrospinous hysteropexy or modified Manchester operation: A discrete choice experiment.BJOG
To investigate women's preference for modified Manchester (MM) or sacrospinous hysteropexy (SH) as surgery for uterine prolapse.
Women's preference for MM or SH.
137 DCEs were completed (1233 choice sets). SH was chosen in 49% of the choice sets, MM in 51%. Of all women, 39 (28%) always chose the same surgery. After exclusion of this group, 882 choice sets were analysed, in which women preferred MM, likely associated with a labelling effect, i.e. description of the procedure, rather than the tested attributes. In that group, MM was chosen in 53% of the choice sets and SH in 47%. When choosing MM, next to the label, dyspareunia was relevant for decision-making. For SH, all attributes were relevant for decision-making.
The preference of women for MM or SH seems almost equally divided. The variety in preference supports the importance of individualised healthcare.
Laparotomy-assisted 2-port fetoscopic repair of spina bifida aperta: report of a single-center experience in Paris, France.Fetal Diagnosis Therapy
Given the maternal morbidity of open fetal surgery, the development of prenatal fetoscopic repair for spina bifida aperta (SBA) is encouraged.
We hereby report the early results from our center, using a laparotomy-assisted CO2-fetoscopic approach.
This study was conducted in patients with an SBA<T1 and >S1, <26 weeks' of gestation, with Chiari II. Fetoscopic repair was performed using 2 operating trocars in the uterus exteriorized through a transverse laparotomy. Endoscopy was performed under humidified and heated CO2 insufflation. Following dissection of the lesion, a 1-layer approach was performed with a muscle/skin flap sutured over a patch of Duragen. Main outcomes were watertight repair at birth and the need for postnatal neurosurgical surgery including shunting within 6 months.
Of 87 women assessed for prenatal therapy, 7 were included. Surgery was performed at 24 (23-26) weeks' gestation. There was no fetal demise. Conversion to hysterotomy was not performed, although surgery could not be performed in one case because of fetal position. Severe preeclampsia developed postoperatively in one case. In the other 6 cases, follow-up was uneventful except for premature rupture membranes which occurred in 3/6 cases at 30, 34 and 36+5-weeks' gestation. Gestational age at delivery was 32+5 (31-36+5) weeks' gestation. Repair was watertight at birth except in two cases which required complementary postnatal surgical repair. Reverse hindbrain herniation during pregnancy was observed in 4/6 cases. In 3/6 cases, shunting was necessary within six months after birth. At 12 months, a functional gain >= 2 metameric levels, was observed in 3 cases of the 6 survivors Conclusion: Laparotomy-assisted fetoscopic repair is a reasonable option for women who choose and are eligible for antenatal surgery, both in terms of maternal and perinatal morbidity.
Risks of single fetal demise after laser for Twin-Twin Transfusion Syndrome.Fetal Diagnosis Therapy
To determine if markers of donor placental insufficiency and recipient cardiac dysfunction increase the risk for single fetal demise (SFD) after laser for Twin-Twin Transfusion Syndrome (TTTS).
Single center retrospective review of patients who had laser for TTTS. Risk factors for donor and recipient demise within one week were compared in pregnancies with SFD and pregnancies with dual survival using Chi square or Fisher's exact test. Multivariate logistic regression was then performed.
Of 398 procedures, 305 (76.6%) had dual survival, 36 (9.0%) had donor demise, 28 (7.0%) had recipient demise and 9 (2.3%) had dual demise. The remaining 20 (5.0%) patients had complicated courses with pregnancy loss or further intervention. In the 64 pregnancies with SFD, 29 (81%) in the donor group and 20 (71%) in the recipient group occurred in the first postoperative week. For the donor demise group, estimated fetal weight (EFW) < 10%, EFW < 3%, EFW < 1%, EFW discordance > 25%, and EFW discordance > 30% did not increase the risk for donor demise except in cases that also had umbilical artery absent or reversed end diastolic flow (AREDF). Donor AREDF was the only independent risk factor for early donor demise. For the recipient demise group, recipient abnormal venous Dopplers were associated with increased risk while EFW discordance > 25% was associated with decreased risk of recipient loss.
In our cohort, donor growth restriction did not increase the risk of early donor demise after laser unless there was also donor AREDF. Donor AREDF was an independent risk factor for donor demise likely due to the severity of placental insufficiency. Abnormal recipient venous Doppler indices increased the risk of early recipient loss while a large intertwin discordance decreased the risk. This may be explained by profound overload in cases with recipient abnormal venous Doppler velocimetry and a lower risk of substantial fluid shifts from a relatively smaller donor territory when there is a large discordance.
Iron Deficiency Anemia and Associated Factors Among Adolescent Girls and Women in a Rural Area of Jatinangor, Indonesia.International Journal of Epidemiology
Iron deficiency anemia is a common problem among adolescent girls and women, with significant consequences on personal health. One of the causes of iron deficiency anemia is inadequate nutritional intake. This study explores iron-deficiency anemia and associated factors among adolescent girls and women in a rural area of Jatinangor, Indonesia.
A cross-sectional study was conducted with 95 adolescent girls and 85 women between April and November 2018. Cluster random sampling was used to select the participants from seven villages in the Jatinangor district. After obtaining informed consent, we collected sociodemographic data, menstrual histories, and related data, including nutritional intake using 24-hour dietary recall. Anthropometrics were gathered to determine the body mass Index (BMI), and venous blood samples were analyzed for complete blood count and hemoglobin levels. Descriptive statistics followed by bivariate and multivariable logistic regression were used to identify anemia-associated factors.
The prevalence of iron deficiency anemia among the girls was 21.1% and 9.4% among women, with an average hemoglobin level in adolescents of 10.75 g/dL (± 0.79) and in adults 11.20 g/dL (± 0.61), whereas MCV was 74.49±8.22 fL in adolescents and 7.61±8.62 fL in adults. The majority of our samples were not stunted in growth and were also within a normal weight range. Multivariate logistic regression analysis showed that protein intake (OR=0.25; 95% CI 0.11-0.58) was a positively associated factor with anemia.
The prevalence of iron-deficiency anemia in this study represents a mild public health problem in the study sample. Based on the hemoglobin level, anemia, can be classified as moderate in adolescents and mild in adults. Low levels of MCH indicate iron-deficiency anemia. Sufficient protein intake did not prevent anemia due to macronutrient and micronutrient intake.

Effect of Surgical Findings on Prediction of Postoperative Ovarian Reserve in Patients with Ovarian Endometrioma.International Journal of Epidemiology
Revised American Society for Reproductive Medicine (rASRM) classification for endometriosis is considered to have limited ability to predict fertility after surgery. This study evaluated the effect of surgical findings described by the rASRM classification on postoperative change in serum Anti-Müllerian hormone (AMH) in endometriosis.
We retrospectively analyzed 112 patients with endometrioma who underwent laparoscopic ovarian cystectomy. The ovarian score was defined as the sum of the endometrioma score from the size and depth of endometrioma and the adhesion score from the extent and types of ovarian adhesion described in the rASRM classification. The ovarian score was correlated with the AMH levels before surgery (AMH0), 3 (AMH3), and 6 months (AMH6) after surgery. To design a model for predicting AMH6, using ovarian score and AMH0, we calculated the unstandardized predictive value of AMH6/AMH0 (UPV) by linear regression analysis. The predicted AMH6 (pAMH6) could be calculated by multiplying the UPV by AMH0. When AMH6 is less than 1.0 ng/mL, it was defined as a poor ovarian reserve group (PORG), and the accuracy of the predictive model was validated.
The level of AMH declined more in rASRM stage IV compared to stage III after surgery. The ovarian score had a significant variable in the linear regression analysis with the ratio of AMH6/AMH0 (p = 0.001). The UPV was correlated with ovarian score negatively. The pAMH6 correlated with AMH6 positively and with age negatively. The pAMH6 showed sensitivity 0.564, specificity 0.909, positive predictive rate 0.786, and negative predictive rate 0.800 in the prediction of PORG (p < 0.001).
The pAMH6 predicted the PORG at 6 months after surgery. Based on the results of our study, the surgical findings, including the size and depth of the endometrioma and extent and types of adhesion could be useful indicators for ovarian reserve after surgery.
Incidence of neonatal sepsis after universal antenatal culture-based screening of group B streptococcus and intrapartum antibiotics: A multicentre retrospective cohort study.BJOG
To compare the incidences of early and late-onset neonatal sepsis, including group B streptococcus (GBS) and Escherichia coli (E. coli) before and after implementation of universal screening and intrapartum antibiotics prophylaxis (IAP).
Maternal GBS colonisation rate, early- and late-onset neonatal sepsis (including GBS and E. coli).
Of 318 740 women with universal culture-based screening, 63 767 women (20.0%) screened positive. After implementation of GBS screening and IAP, the incidence of early-onset neonatal sepsis decreased (3.25 versus 2.26 per 1000 live births, p < 0.05), including those caused by GBS (1.03 versus 0.26 per 1000 live births, p < 0.05). Segmented regression showed that change in early-onse GBS sepsis incidence after screening was the only significant variable in the outcome trend. There was no significant evidence of increase in incidence of late-onset neonatal sepsis including those caused by GBS.
Universal culture-based GBS screening and IAP were associated with reduction in early-onset neonatal sepsis including GBS disease. Although an increase in incidence of late-onset neonatal sepsis including those caused by GBS cannot be totally ruled out, we did not identify significant evidence that this occurred.
Emergency Contraceptive Pill Use and its Impact on Condom Utilization Among University Students: A Cross-Sectional Study.International Journal of Epidemiology
Emergency contraceptive pills (ECPs) prevent unplanned pregnancy but not sexually transmitted infections (STIs), and the practice of ECP may affect condom use. This study, therefore, aimed to assess ECP use and its impact on condom utilization among female students of private universities in Nekemte town, western Ethiopia.
An institution-based cross-sectional study was conducted on 400 female students in three different private universities from February 1 to 28, 2019. Study samples were selected through simple random sampling technique. Data collected from a structured self-administered questionnaire were analyzed using SPSS version 23.0. Bivariate and multivariate logistic regression were performed to determine factors associated with condom utilization, and statistical significance was set at 95% confidence interval (CI) using a p-value of <0.05 as a cutoff point.
The response rate was 95.3% (381/400). Overall, 51.4% (196/381; 95% CI = 45.1%, 57.7%) had awareness of ECP. Besides, 186 (48.8%) students reported history of sexual intercourse, of which 115 (61.8%) have ever practiced ECP and 96 (51.6%) have ever used condom. However, only 11 (5.9%) have ever utilized ECP and condom concurrently. Use of ECPs (adjusted odds ratio (AOR) = 0.32; 95% CI = 0.164, 0.632; p = 0.001), belief that condom prevents STI (AOR = 3.17; 95% CI = 1.045, 8.646; p = 0.041) and thought that ECP does not prevent STI (AOR = 2.217; 95% CI = 1.172, 4.59; p = 0.032) had statistically significant association with condom utilization.
The practice of ECP was average, while dual method contraception use was low in the study area. History of ECP use and beliefs that ECP is not effective to prevent STI or condom protects against STI were factors associated with condom use.
Predictors of Hepatitis B Virus Infection Vaccine Hesitancy Among Pregnant Women Attending Antenatal Care at Lubaga Hospital, Kampala, Uganda.International Journal of Epidemiology
While hepatitis B virus infection may be seen as a global threat within the medical and scientific community, primary prevention via vaccination remains the most effective approach towards breaking the chain of transmission of HBV infection. However, vaccination uptake in Uganda has been modest despite a very endemic national figure resulting from the vertical transmission of this infection. This study assessed the predictors of HBV vaccine hesitancy among pregnant women attending Antenatal clinic in Central Uganda.
A hospital-based cross-sectional study employing a five-sectioned pretested interviewer-administered questionnaire was conducted to obtain data from 385 consenting pregnant women. Responses for the antecedent variables were transformed into weighted aggregate scores using SPSS version 26. Multivariable logistic regression analysis was employed to ascertain the predictors of HBV vaccine hesitancy with the cut-off for hypotheses set at 5% level of significance.
The majority of the respondents (59%) were between the ages of 18 and 28 years. Women with secondary educational attainment were predominant (42.3%). The respondents had mean scores of 5.97±6.61, 17.10±18.31, and 12.39±13.37, respectively, computed for knowledge of HBV infection, perception, and behavioral skills towards HBV prevention. Regarding vaccine hesitancy, three-quarters of the women (74%) hesitated to uptake HBV vaccine. While negative significant associations exist between marital status (AOR = 0.47, 95% CI = 0.22-1.01), knowledge (AOR = 0.79, 95% CI = 0.70-0.89), behavioral skills (AOR = 0.88, 95% CI = 0.81-0.95) and vaccine hesitancy, level of education (AOR = 1.88, 95% CI = 1.08-3.27) and perception (AOR = 1.11, 95% CI = 1.05-1.18) on the other hand, positively predicted vaccine hesitancy.
The findings reported an extremely high degree of HBV vaccine hesitancy among the expectant mothers discovered to be linked with marital status, educational attainment, HBV-specific knowledge, perception and behavioral skills. This necessitates targeted health education for married women with lower educational attainment to improve their knowledge which will in turn shape their perception and behavioral skills towards satisfactory uptake of HBV vaccine.
AOSRV: Development and preliminary performance assessment of a new robotic system for autonomous percutaneous vertebroplasty.Int J Med
Percutaneous vertebroplasty (PVP) is one of the most effective treatments for patients with vertebral fracture that need surgical treatment, and surgical robotics are promising tools to provide surgeons with improved precision, surgical efficiency and reduce radiation exposure. However, there are currently few robotics that are developed to help assist with PVP.
A new spinal surgical robotic system "AOSRV" for autonomous vertebral puncture and bone cement injection was designed and customized in this study. To investigate its practical abilities and the advantages, we performed single-segment/double-segment PVP simulation surgeries on pig spinal specimens manually and using AOSRV.
By contrast with the freehand group (FG) in single-segment (SS)/double-segment (DS) surgery, the robotic group (RG) was superior in the operation time (RGSS = 21.14 ± 4.11 min, FGSS = 33.17 ± 6.83 min; RGDS = 42.39 ± 7.31 min, FGDS = 62.86 ± 20.39 min), puncture adjustments (RGSS = 2.30 ± 1.77, FGSS = 14.86 ± 5.46; RGDS = 3.91 ± 1.76, FGDS = 20.00 ± 7.76), intraoperative fluoroscopies (RGSS = 4.10 ± 1.52, FGSS = 20.57 ± 5.44; RGDS = 7.82 ± 1.40, FGDS = 25.91 ± 7.23) and bone cement leakage rate (RGSS = 30%, FGSS = 71.4%; RGDS = 38.6%, FGDS = 83.3%).
AOSRV was successfully developed and had a promising preliminary performance. An innovative attempt was made for the blank space of the autonomous vertebroplasty surgical robotics, and it may shed a light on more promising applications in the future.

Effect of Aerobic Exercises in Improving Premenstrual Symptoms Among Healthy Women: A Systematic Review of Randomized Controlled Trials.International Journal of Epidemiology
Premenstrual symptoms in women of reproductive age are associated with substantial distress and functional impairments. A healthy lifestyle is the first step to manage premenstrual symptoms. Recreational physical activities have been recommended as an alternative to medical management in easing premenstrual symptoms.
The objective of this systematic review is to analyze the effects of aerobic exercises in improving premenstrual symptoms among healthy women.
Randomized controlled trials (RCTs) published from inception to February 2022, were searched using keywords in electronic databases such as, SCOPUS, PubMed, PEDro, Cochrane and web of science. RCTs published in English, comparing the effects of aerobic exercise with other interventions or controls were included. PEDro scale and Cochrane collaboration tool for risk of bias was used to assess the methodological quality of included trials. Data from the included study and the participant's characteristics, interventions, outcome and results were extracted.
Five RCTs with 492 participants were included in this systematic review. Methodological quality assessed by PEDro (4.8/10) and Cochrane collaboration tool for risk of bias were moderate. Allocation concealment, blinding of participants and outcome assessors were the most common bias in all included studies. Walking, swimming and running were the common aerobic exercises performed in the RCTs. Aerobic exercise is effective in improving physical physiological symptoms among women with premenstrual syndrome (PMS).
Aerobic exercises are effective in improving premenstrual symptoms. This review provides moderate evidence for improving hematological parameters during PMS. Further RCTs with long term follow up and quality of life would consolidate our findings.
