Performance of Ductus Venosus Doppler (at 11-13 + 6 Weeks) in Predicting Adverse Fetal Outcomes in Indian Population: Going Beyond Aneuploidies: Going Beyond Aneuploidies.

OBJECTIVES: The objective of this study is to examine the performance of Ductus venosus (DV) Doppler done at the routine first trimester screening (11-13 + 6 weeks) in predicting the adverse fetal outcomes in Indian population. METHODS: This observational study was conducted between 2013 and 2019, on 4340 singleton pregnancies. Ductus Doppler were considered abnormal if DV pulsatility index values were >95th centile for that gestation or with a reversed "a" wave. Anatomical survey was done to rule out other abnormalities. Women were followed up till delivery and outcomes were divided into 4 groups: 1) aneuploidies; 2) cardiac defects; 3) non-cardiac structural abnormalities; and 4) miscarriages before 24 weeks or fetal deaths after 24 weeks. RESULTS: Prevalence of abnormal DV Doppler is 5.12% (205/4004). There were significantly higher number of fetal losses (4.4 versus 0.3%), aneuploidies (10.2 versus 1.7%), fetal cardiac defects (5.9 versus 1.4%), and non-cardiac structural defects (5.4 versus 1.4%) among the pregnancies with abnormal DV Doppler in comparison to those with normal flow (P < .001). Logistic regression analysis has shown that significant contribution to fetal chromosomal abnormalities and cardiac defects was associated with abnormal DV. Other factors which were found to have a significant association with adverse fetal outcome were increased nuchal translucency and increased body mass index (BMI). CONCLUSION: DV Doppler in first trimester can be used as a screening tool for cardiac defects and fetal deaths. Women with abnormal DV Dopplers should be offered fetal echocardiography at 18-22 weeks and third trimester growth scans with Dopplers.

Factors associated with intrapartum cesarean section after a successful external cephalic version.

PURPOSE: External cephalic version (ECV) is an effective procedure to reduce the breech presentation at term reducing the chances of cesarean section. However even after successful ECV reports suggests the risk of having a cesarean section is high. The study analyzes the mode of delivery after a successful ECV and to identify the factors associated with intrapartum cesarean delivery compared to those with spontaneous cephalic presentation. METHODS: This study was based on labor and delivery details, from the ECV registers, of 430 women who had successful ECV and they compared to those with spontaneous cephalic presentation. Primary outcome was delivery by cesarean section. Multiple logistic regression model was used to assess independent association of frisk factors associated with intrapartum cesarean section delivery by cesarean section and were presented as Odds Ratio (OR) and 95% confidence interval. RESULTS: Cesarean section rates were similar among those who had a successful ECV and those with spontaneous cephalic presentation (22.3% vs 20.1%, p = 0.298). Women who had a successful ECV (OR = 1.5; (95%CI 1.13-1.98), maternal age (OR1.06-1.03-1.09), and previous delivery by cesarean section (OR = 5.16 (95%CI; 1.88-14.16) were found to associated with intrapartum cesarean section after adjusting for other factors. CONCLUSION: Women who had a successful ECV had an increased risk of intrapartum cesarean section compared those women with spontaneous cephalic presentation. Further research should be performed to identify more risk factors, which could optimize intra-partum care to reduce the risk of cesarean section for women after successful ECV.

Elective Fetal Reduction in Dichorionic Diamniotic Twin Pregnancies on Parental Request: A Single-Centre Experience.

OBJECTIVES: Our study aimed to examine a subset of electively reduced twins and compare their outcomes with those of expectantly managed twins, along with a cohort of singleton pregnancies. The secondary aim was to ascertain the procedure-related miscarriage risks. METHODS: A retrospective cohort analysis was performed at Apollo Centre for Fetal Medicine, New Delhi, comparing pregnancy outcomes in dichorionic diamniotic twin pregnancies which were reduced to singletons (group 1) with that of women with dichorionic twins managed expectantly (group 0) and women with a singleton pregnancy (group 2). Comparison of continuous and categorical variables was conducted using standard statistical tests. RESULTS: We analysed 35 twins which were reduced to singletons, 421 expectantly managed dichorionic twins and 1915 women with a singleton pregnancy. In the reduction group, the rate of procedure related pregnancy loss<24 weeks was lower, compared to the expectantly managed twins, although the difference was not statistically significant (5.71% [2/35] vs. 7.13% [30/421]; p = 1.000). The median gestational age at delivery was significantly higher in reduced twins compared to expectantly managed twin pregnancies (38.0 vs. 35.4 weeks respectively, p < 0.001) with a higher mean birth weight at delivery, both of which were comparable to that among the singleton pregnancies (38.3 weeks). The rates of preterm birth <32 weeks and <34 weeks in the expectantly managed twins were significantly higher at 19.8% (66/334) and 25.7% (86/334) compared to the reduced twins, all of whom delivered beyond 34 weeks. The rates of preterm births <32 weeks, <34 weeks, and the late preterm births in the reduced twins were comparable to those in the singleton cohort. CONCLUSIONS: The obstetric and perinatal outcomes after reduction of a dichorionic twin are better than an expectantly managed twin without an associated increase in pregnancy loss rates. Fetal reduction of dichorionic twin to a singleton appears to be a safe procedure in expert hands.

Development and validation of a clinical score to predict the probability of successful procedure in women undergoing external cephalic version.

INTRODUCTION: External Cephalic Version (ECV) reduces breech presentation at term and thus contribute to the reduction of cesarean section. This study was done to determine the factors associated with the successful ECV in women with breech presentation after 36 weeks' gestation and also to develop and validate a clinical score which could be utilized for individual patient counseling in future. METHODS: This was a retrospective cohort study conducted in a tertiary care center and teaching hospital in south India. Prospectively collected data from the register maintained for all ECVs performed on pregnant women with breech presentation at or more than 36 weeks' gestation. Clinical and ultrasound parameters at the time of performing the procedure were used in the analysis. Multiple logistic regression with a stepwise backward selection procedure was used selecting potential variable to construct the model and internal validation was done with bootstrapping. Primary outcome was successful ECV defined as cephalic presentation at the end of the procedure. RESULTS: Among 611 women who underwent ECV, it was successful in 70.4%. In the multiple logistic regression model, multiparity (OR4.48), AFI ≥ 7 (OR = 3.06), type of breech, posterior placental location (OR = 1.57), sacro-anterior position of breech (OR = 2.83), normal uterine tone (OR = 1.82) and fetal pole not engaged (OR = 2.82) were found to be predictive of successful ECV with good discrimination (AUC = 0.782) and acceptable calibration. Combining these factors from the model a predictive score (score 0-13) is proposed for clinical utility. CONCLUSIONS: Combining clinical and ultrasound parameters into a predictive score, which is simple and effective, could be utilized in the clinical practice, once validated externally.

What motivates serodiscordant couples to prevent HIV transmission within their relationships: findings from a PrEP implementation study in Kenya.

With the planned scale-up of pre-exposure prophylaxis (PrEP) for HIV prevention among serodiscordant couples in resource-limited settings, gaining an understanding of what motivates serodiscordant couples to prevent HIV is critical. We conducted 44 semi-structured, in-depth individual or couple interviews with 63 participants (33 HIV-infected and 30 HIV-uninfected participants) enrolled in a prospective implementation study of oral antiretroviral-based prevention in Kisumu, Kenya. Transcripts were iteratively analysed using inductive content analysis. Findings point to the importance of maintaining the emotional and economic stability of the partnership and family as motivators in preventing HIV transmission. Female participants identified fear of blame or potential violence for transmitting HIV as a motivator. Furthermore, couples primarily held the HIV-infected individual responsible for HIV prevention, but also held women more accountable for the use of prevention methods such as condoms. These themes substantiate traditional gender norms but also reveal how dyadic interdependence challenges these norms. As programmes in resource-limited settings scale up PrEP access, they should simultaneously capitalise on HIV serodiscordant couples' motivations for HIV prevention and address gender norms so women do not find themselves unduly responsible for the prevention of HIV transmission.

Matched cohort study of external cephalic version in women with previous cesarean delivery.

OBJECTIVE: To evaluate the efficacy and safety of external cephalic version (ECV) among women with previous cesarean delivery. METHODS: A retrospective study was conducted using data for women with previous cesarean delivery and breech presentation who underwent ECV at or after 36 weeks of pregnancy during 2011-2016. For every case, two multiparous women without previous cesarean delivery who underwent ECV and were matched for age and pregnancy duration were included. Characteristics and outcomes were compared between groups. RESULTS: ECV was successful for 32 (84.2%) of 38 women with previous cesarean delivery and 62 (81.6%) in the control group (P=0.728). Multivariate regression analysis confirmed that previous cesarean was not associated with ECV success (odds ratio 1.89, 95% confidence interval 0.19-18.47; P=0.244). Successful vaginal delivery after successful ECV was reported for 19 (59.4%) women in the previous cesarean delivery group and 52 (83.9%) in the control group (P<0.001). No ECV-associated complications occurred in women with previous cesarean delivery. CONCLUSION: To avoid a repeat cesarean delivery, ECV can be offered to women with breech presentation and previous cesarean delivery who are otherwise eligible for a trial of labor.

"Since both of us are using antiretrovirals, we have been supportive to each other": facilitators and barriers of pre-exposure prophylaxis use in heterosexual HIV serodiscordant couples in Kisumu, Kenya.

INTRODUCTION: Since 2015, the World Health Organization recommends pre-exposure prophylaxis (PrEP) for all persons at substantial risk for HIV, including HIV-uninfected partners in serodiscordant relationships in resource-limited settings. As PrEP moves from clinical trials to real-world use, understanding facilitators of and barriers to PrEP initiation and adherence is critical to successful PrEP implementation and rollout. METHODS: We conducted 44 in-depth individual or couple interviews with 63 participants (30 without HIV and 33 with HIV) enrolled in the Partners Demonstration Project in Kisumu, Kenya, between August and September 2014. The semi-structured interviews discussed the following: 1) perceived advantages and disadvantages of antiretroviral therapy (ART)/PrEP; 2) reasons for accepting or declining ART/PrEP and 3) influence of prevention of transmission to partner or infant on ART/PrEP use. Transcripts from the interviews were iteratively analyzed using inductive content analysis. RESULTS: Our study identified three key factors that may facilitate initiation of PrEP in this population. First, participants using PrEP felt reduced stress and increased trust in their HIV serodiscordant relationships. Second, greater community-wide knowledge of PrEP was thought to likely increase PrEP acceptance. Third, greater education and counselling by providers on PrEP use was also considered to likely increase the adoption of PrEP. We also identified three key barriers to initiation of and adherence to PrEP. First, most participants who declined PrEP expressed doubts about the relative additional effectiveness of PrEP in combination with other prevention tools. Second, perceived stigma related to PrEP use was an important barrier to PrEP initiation. Third, many struggled with overcoming perceived side effects or logistical challenges of taking daily PrEP, particularly when they themselves were not ill. CONCLUSIONS: Leveraging the facilitators and overcoming barriers to PrEP uptake may enhance the successful rollout of PrEP among HIV serodiscordant couples in Kenya and other areas in sub-Saharan Africa, thereby reducing sexual transmission of HIV. Further research focused on how best to provide counselling on combination HIV prevention tools in the context of PrEP use is a crucial next step to delivering PrEP.

Facilitators and Barriers of Antiretroviral Therapy Initiation among HIV Discordant Couples in Kenya: Qualitative Insights from a Pre-Exposure Prophylaxis Implementation Study.

INTRODUCTION: The World Health Organization now recommends antiretroviral therapy (ART) initiation for all HIV-infected individuals regardless of CD4 cell count or disease status. Understanding the facilitators and barriers to initiation of and adherence to ART is essential to successful scale-up of "universal" ART. METHODS: To investigate facilitators and barriers to ART initiation, we conducted 44 in-depth individual or couple interviews with 63 participants (33 participants with HIV and 30 without HIV) already enrolled in a prospective implementation study of oral antiretroviral-based prevention in Kisumu, Kenya between August and September 2014. A semi-structured interview guided discussions on: 1) perceived advantages and disadvantages of ART; 2) reasons for accepting or declining ART initiation; and 3) influence of prevention of transmission to partner or infant influencing ART use. Transcripts from the interviews were iteratively analyzed using inductive content analysis. RESULTS: HIV-infected participants indicated that living a healthier life, preventing HIV transmission to others, and appearing "normal" or "healthy" again facilitated their initiation of ART. While appearing "normal" allowed these individuals to interact with their communities without stigmatization, they also perceived community opposition to their initiating ART, because appearing "normal" again prevented community members from easily identifying infected individuals in their community. Denial of diagnosis, disclosure stigma, perceived side-effects, and challenges in obtaining refills were additional barriers to ART initiation. CONCLUSIONS: Community perceptions play an important role in both facilitating and inhibiting ART initiation. Perceived stigma, including perceived community opposition to widespread ART use, is an important barrier to ART initiation. Addressing such barriers, while capitalizing on facilitators, to ART initiation should be central to universal ART scale-up efforts.
