Item Achieving UNAIDS 90-90-90 targets for pregnant and postpartum women in sub-Saharan Africa: progress, gaps and research needs(Mediscript, 2018-11-15) Abuogi, Lisa L.; Humphrey, John M.; Mpody, Christian; Yotebieng, Marcel; Murnane, Pamela M.; Clouse, Kate; Otieno, Lindah; Cohen, Craig R.; Wools-Kaloustian, Kara; Medicine, School of MedicineThe implementation of the 2013 World Health Organization Option B+ recommendations for HIV treatment during pregnancy has helped drive significant progress in achieving universal treatment for pregnant and postpartum women in sub-Saharan Africa (SSA). Yet, critical research and implementation gaps exist in achieving the UNAIDS 90-90-90 targets. To help guide researchers, programmers and policymakers in prioritising these areas, we undertook a comprehensive review of the progress, gaps and research needs to achieve the 90-90-90 targets for this population in the Option B+ era, including early infant HIV diagnosis (EID) for HIV-exposed infants. Salient areas where progress has been achieved or where gaps remain include: (1) knowledge of HIV status is higher among people with HIV in southern and eastern Africa compared to western and central Africa (81% versus 48%, UNAIDS); (2) access to antiretroviral therapy (ART) for pregnant women has doubled in 22 of 42 SSA countries, but only six have achieved the second 90, and nearly a quarter of pregnant women initiating ART become lost to follow-up; (3) viral suppression data for this population are sparse (estimates range from 30% to 98% peripartum), with only half of women maintaining suppression through 12 months postpartum; and (4) EID rates range from 15% to 62%, with only three of 21 high-burden SSA countries testing >50% HIV-exposed infants within the first 2 months of life. We have identified and outlined promising innovations and research designed to address these gaps and improve the health of pregnant and postpartum women living with HIV and their infants.Item Development of a Generic Physiologically-Based Pharmacokinetic Model for Lactation and Prediction of Maternal and Infant Exposure to Ondansetron via Breast Milk(Wiley, 2022) Job, Kathleen M.; Dallmann, André; Parry, Samuel; Saade, George; Haas, David M.; Hughes, Brenna; Berens, Pamela; Chen, Jia-Yu; Fu, Christina; Humphrey, Kelsey; Hornik, Christoph; Balevic, Stephen; Zimmerman, Kanecia; Watt, Kevin; Obstetrics and Gynecology, School of MedicineOndansetron is commonly used in breastfeeding mothers to treat nausea and vomiting. There is limited information in humans regarding safety of ondansetron exposure to nursing infants and no adequate study looking at ondansetron pharmacokinetics during lactation. We developed a generic physiologically based pharmacokinetic lactation model for small molecule drugs and applied this model to predict ondansetron transfer into breast milk and characterize infant exposure. Drug-specific model inputs were parameterized using data from the literature. Population-specific inputs were derived from a previously conducted systematic literature review of anatomic and physiologic changes in postpartum women. Model predictions were evaluated using ondansetron plasma and breast milk concentration data collected prospectively from 78 women in the Commonly Used Drugs During Lactation and infant Exposure (CUDDLE) study. The final model predicted breast milk and plasma exposures following a single 4 mg dose of intravenous ondansetron in 1000 simulated women who were two days postpartum. Model predictions showed good agreement with observed data. Breast milk median prediction error (MPE) was 18.4% and median absolute prediction error (MAPE) was 53.0%. Plasma MPE was 32.5% and MAPE was 43.2%. The model-predicted daily and relative infant doses were 0.005 mg/kg/day and 3.0%, respectively. This model adequately predicted ondansetron passage into breast milk. The calculated low relative infant dose indicates that mothers receiving ondansetron can safely breastfeed. The model building blocks and population database are open-source and can be adapted to other drugs.Item Early Pregnancy Atherogenic Profile in a First Pregnancy and Hypertension Risk 2 to 7 Years After Delivery(American Heart Association, 2021-02) Catov, Janet M.; McNeil, Rebecca B.; Marsh, Derek J.; Mercer, Brian M.; Merz, C. Noel Bairey; Parker, Corette B.; Pemberton, Victoria L.; Saade, George R.; Chen, Yii-Der (Ida); Chung, Judith H.; Ehrenthal, Deborah B.; Grobman, William A.; Haas, David M.; Parry, Samuel; Polito, LuAnn; Reddy, Uma M.; Silver, Robert M.; Simhan, Hyagriv N.; Wapner, Ronald J.; Kominiarek, Michelle; Kreutz, Rolf; Levine, Lisa D.; Greenland, Philip; Obstetrics and Gynecology, School of MedicineBackground: Cardiovascular risk in young adulthood is an important determinant of lifetime cardiovascular disease risk. Women with adverse pregnancy outcomes (APOs) have increased cardiovascular risk, but the relationship of other factors is unknown. Methods and Results: Among 4471 primiparous women, we related first-trimester atherogenic markers to risk of APO (hypertensive disorders of pregnancy, preterm birth, small for gestational age), gestational diabetes mellitus (GDM) and hypertension (130/80 mm Hg or antihypertensive use) 2 to 7 years after delivery. Women with an APO/GDM (n=1102) had more atherogenic characteristics (obesity [34.2 versus 19.5%], higher blood pressure [systolic blood pressure 112.2 versus 108.4, diastolic blood pressure 69.2 versus 66.6 mm Hg], glucose [5.0 versus 4.8 mmol/L], insulin [77.6 versus 60.1 pmol/L], triglycerides [1.4 versus 1.3 mmol/L], and high-sensitivity C-reactive protein [5.6 versus 4.0 nmol/L], and lower high-density lipoprotein cholesterol [1.8 versus 1.9 mmol/L]; P<0.05) than women without an APO/GDM. They were also more likely to develop hypertension after delivery (32.8% versus 18.1%, P<0.05). Accounting for confounders and factors routinely assessed antepartum, higher glucose (relative risk [RR] 1.03 [95% CI, 1.00-1.06] per 0.6 mmol/L), high-sensitivity C-reactive protein (RR, 1.06 [95% CI, 1.02-1.11] per 2-fold higher), and triglycerides (RR, 1.27 [95% CI, 1.14-1.41] per 2-fold higher) were associated with later hypertension. Higher physical activity was protective (RR, 0.93 [95% CI, 0.87-0.99] per 3 h/week). When evaluated as latent profiles, the nonobese group with higher lipids, high-sensitivity C-reactive protein, and insulin values (6.9% of the cohort) had increased risk of an APO/GDM and later hypertension. Among these factors, 7% to 15% of excess RR was related to APO/GDM. Conclusions: Individual and combined first-trimester atherogenic characteristics are associated with APO/GDM occurrence and hypertension 2 to 7 years later.Item Familial aggregation of postpartum mood symptoms in bipolar disorder pedigrees(Wiley, 2008-02) Payne, Jennifer L; MacKinnon, Dean F.; Mondimore, Francis M.; McInnis, Melvin G.; Schweizer, Barbara; Zamoiski, Rachel B.; McMahon, Francis J.; Nurnberger, John I., Jr.; Rice, John P.; Scheftner, William; Coryell, William; Berrettini, Wade H.; Kelsoe, John R.; Byerley, William; Gershon, Elliot S.; DePaulo, J. Raymond, Jr.; Potash, James B.; Medicine, School of MedicineOBJECTIVES: We sought to determine if postpartum mood symptoms and depressive episodes exhibit familial aggregation in bipolar I pedigrees. METHODS: A total of 1,130 women were interviewed with the Diagnostic Interview for Genetic Studies as part of the National Institute of Mental Health (NIMH) Genetics Initiative Bipolar Disorder Collaborative Study and were asked whether they had ever experienced mood symptoms within four weeks postpartum. Women were also asked whether either of two major depressive episodes described in detail occurred postpartum. We examined the odds of postpartum mood symptoms in female siblings, who had previously been pregnant and had a diagnosis of bipolar I, bipolar II, or schizoaffective (bipolar type) disorders (n = 303), given one or more relatives with postpartum mood symptoms. RESULTS: The odds ratio for familial aggregation of postpartum mood symptoms was 2.31 (p = 0.011) in an Any Mood Symptoms analysis (n = 304) and increased to 2.71 (p = 0.005) when manic symptoms were excluded, though this was not significantly different from the Any Mood Symptoms analysis. We also examined familial aggregation of postpartum major depressive episodes; however, the number of subjects was small. CONCLUSIONS: Limitations of the study include the retrospective interview, the fact that the data were collected for other purposes and the inability to control for such factors as medication use. Taken together with previous studies, these data provide support for the hypothesis that there may be a genetic basis for the trait of postpartum mood symptoms generally and postpartum depressive symptoms in particular in women with bipolar disorder. Genetic linkage and association studies incorporating this trait are warranted.Item The First 4 Weeks Postpartum: The Mother’s Breastfeeding Concerns and Support(Office of the Vice Chancellor for Research, 2015-04-17) Rosales, Stacy A.; Shieh, Carol; Bakas, Tamilyn; Busby, KatieObjective: The first four weeks postpartum are critical for establishing successful breastfeeding because many women wean or stop exclusive breastfeeding during this time. This study explored the breastfeeding concerns of mothers during the first 4 weeks postpartum and the support sought for those concerns. Design: A qualitative approach was used. Participants: Four mothers, recruited from central Indiana in 2014 through social media or word of mouth participated in the study. Inclusion criteria were women in their first four to six weeks postpartum, delivered full term healthy babies and were discharged from the hospital breastfeeding. Methods: Semi-structured telephone interviews were conducted and data were analyzed using content analysis. Interview transcripts were first coded. Codes with similar meaning were grouped into categories. Categories sharing similar features were again collapsed into common themes. Results: Concerns identified by mothers fell into the themes: Infant breastfeeding difficulties (latch), breast complications related to breastfeeding (pain and nipple trauma), and maternal concerns related to milk production (infant milk intake and milk supply). Four common themes of support were identified that mothers utilized to alleviate concerns: Professional support, informational support, peer support, and family support. Conclusions: Mothers identified concerns related to themselves and their infants with respect to breastfeeding in the first four weeks postpartum. These concerns indicate the women’s struggle with establishing a successful breastfeeding pattern and one that is compromised by infant latch difficulty, nipple pain and inadequate milk production. Support was sought at multiple levels from health care professionals to social media. The findings suggest that support from health care professionals who provide valuable information is important. However, postpartum women also utilize other support methods when encountering breastfeeding concerns in the first four weeks postpartum. When developing interventions to assist postpartum women with establishing breastfeeding outside of the hospital setting, nurses need to consider using social media and social networks as resources for breastfeeding information and support.Item The Health Care Encounters of Pregnant and Postpartum Women With Substance Use Disorders(2020-06) Renbarger, Kalyn Marie; Draucker, Claire Burke; Shieh, Carol; Moorman, Meg; Latham-Mintus, KenziePregnant and postpartum women with substance use disorders (SUDs) are likely to experience adverse health care encounters that contribute to poor health outcomes for them and their infants. The purpose of this dissertation is to describe the health care encounters of pregnant and postpartum women with SUDs. This dissertation includes two studies. The first study is a metasynthesis of published qualitative studies using a metasummary approach to classify the types of health care encounters experienced by pregnant and postpartum women with SUDs. A taxonomy of health care encounters was developed. Five types of adverse encounters were identified and labeled as (a) judgmental, (b) disparaging, (c) scrutinizing, (d) disempowering, and (e) deficient care. Three types of beneficial encounters were identified and labeled as (a) recovery-based, (b) accepting, and (c) effective care. The second study was a qualitative descriptive study conducted to describe factors that influence the formation of trusting relationships between maternity nurses and pregnant and postpartum women with SUDs. Interviews with 15 maternity nurses and 10 pregnant and postpartum women with SUDs were conducted. Content analysis of the participant narratives revealed a number of characteristics of maternity nurses and pregnant and postpartum women with SUDs that helped or hindered trusting relationships. Six characteristics of maternity nurses were identified and labeled as (a) rapport-building with women, (b) demeanor toward women, (c) provision of care, (d) provision of information, (e) attitude toward substance use, and (f) addiction expertise. Five characteristics of the women were identified and labeled as (a) engagement with nurses, (b) demeanor toward nurses, (c) acceptance of care, (d) investment in recovery, and (e) bonding with infant. Adverse encounters were often associated with provider stigma related to substance use during pregnancy and limited provider knowledge related to addiction. The findings will contribute to the development of strategies to improve the health care encounters of this population by promoting stigma awareness and communication skills training.Item Laser Acupuncture Analgesia on Postpartum Low Back Pain: A Prospective Randomized Controlled Study(Elsevier, 2023-02) Cheng, Hsuesh-Yu; Wu, Bei-Yu; Tung, Tao-Hsin; Shieh, Carol; Liu, Chun-Ting; School of NursingBackground Unresolved postpartum LBP may affect women...s physical and psychological health. Aim To investigate the analgesic effects of laser acupuncture therapy (LAT) for postpartum LBP. Method Postpartum women with LBP were recruited and randomly assigned to the intervention group or the control group from November 2017 to July 2018. The participants in the intervention group received LAT and standard care. The participants in the control group received only standard care. The primary outcome was the Visual Analogue Scale for LBP. Secondary outcomes were limitation of daily activities and physical activity; perceived stress scale; and salivary cortisol values. Results In all, 106 participants were recruited and assigned to the intervention group or the control group. As compared with the control group, the participants in the LAT group had significantly lower intensity of LBP (mean ± SD: 1.21 ± 0.99 vs 3.25 ± 1.14; p < .001), limitations of daily activities (mean ± SD: 3.17 ± 2.09 vs 10.40 ± 4.72; p < .001) and physical activity (mean ± SD: 3.04 ± 2.17 vs 9.79 ± 4.71; p < .001), perceived stress (mean ± SD: 26.13 ± 3.97 vs 28.85 ± 4.26; p = .001), and salivary cortisol levels (mean ± SD: 0.194 ± 0.131 vs 0.280 ± 0.234; p = .02) post-intervention. Conclusions For postpartum LBP, LAT combined with standard care had greater analgesic efficacy, lower perceived stress, lower limitations of daily activities and physical activity, and lower salivary cortisol levels than standard care alone.Item The Mother's Lived Experience of Breastfeeding in the First 4 Weeks Postpartum: A Heideggerian Hermeneutic Phenomenological Analysis(2021-04) Rosales, Stacy Ann; Stiffler, Deborah; Bute, Jennifer J.; Shieh, Carol; Wallace, Linda S.The benefits of breastfeeding are widely known and documented, yet breastfeeding rates at six months have remained well below desired levels. In order to fully understand the breastfeeding experience in the early postpartum period and all the intricacies involved, researchers need to provide mothers with the opportunity to talk about their experiences during the time when there are the most difficulties and when they are most likely to discontinue, the first four weeks postpartum. The purpose of this study was to more fully understand, in their own words, the experiences of mothers who began breastfeeding their infant after birth and may or may not have been breasting at four weeks postpartum. A single research question guided this study: What are the lived experiences of breastfeeding mothers during the first four weeks postpartum? Eight mothers who delivered in the past four to six weeks were interviewed. Data were analyzed using a Heideggerian hermeneutic phenomenological approach. This method was chosen because it allowed the researcher to conduct interviews and explore the lived experience of breastfeeding mothers and to uncover the concealed meaning within the phenomena. This methodology provided a richness that might not be possible through description alone. The narratives shared by the mothers demonstrated that initiating breastfeeding and sustaining it in the early postpartum period was a complex process. Each mother’s breastfeeding experience was unique to her but also similar to someone else’s. The overall constitutive pattern of Getting the Hang of It was selected and consisted of four themes and nine subthemes. The four themes included: Physical Experiences, Emotional Complexities, Infant Involvement in Breastfeeding Process, and Support. These themes and their subsequent subthemes provide insight into the complexities experienced by mothers in order to acquire the skills they needed to breastfeed their infants. Breastfeeding mothers, who have had favorable and unfavorable experiences, are willing to share a wealth of information. Health professionals should encourage mothers to talk about their experiences and listen to what they are saying. Through listening they can provide mothers with the resources and support needed to meet their breastfeeding goals.Item Outcomes After Loss to Follow-Up for Pregnant and Postpartum Women Living With HIV and Their Children in Kenya: A Prospective Cohort Study(Wolters Kluwer, 2024) Humphrey, John; Kipchumba, Bett; Alera, Marsha; Sang, Edwin; Musick, Beverly; Muli, Lindah; Kipsang, Justin; Songok, Julia; Yiannoutsos, Constantin; Wools-Kaloustian, Kara; Medicine, School of MedicineBackground: Many prevention of vertical transmission (PVT) studies assess outcomes within 12 months postpartum and exclude those lost to follow-up (LTFU), potentially biasing outcomes toward those retained in care. Setting: Five public facilities in western Kenya. Methods: We recruited women living with HIV (WLH) ≥18 years enrolled in antenatal clinic (ANC). WLH retained in care (RW) were recruited during pregnancy and followed with their children through 6 months postpartum; WLH LTFU (LW, last visit >90 days) after ANC enrollment and ≤6 months postpartum were recruited through community tracing. Recontact at 3 years was attempted for all participants. Primary outcomes were retention and child HIV-free survival. Generalized linear regression was used to estimated risk ratios (RRs) for associations with becoming LTFU by 6 months postpartum, adjusting for age, education, facility, travel time to facility, gravidity, income, and new vs. known HIV positive at ANC enrollment. Results: Three hundred thirty-three WLH (222 RW, 111 LW) were recruited from 2018 to 2019. More LW versus RW were newly diagnosed with HIV at ANC enrollment (49.6% vs. 23.9%) and not virally suppressed at study enrollment (40.9% vs. 7.7%). 6-month HIV-free survival was lower for children of LW (87.9%) versus RW (98.7%). At 3 years, 230 WLH were retained in care (including 51 previously LTFU before 6 months), 30 transferred, 70 LTFU, and 3 deceased. 3-year child HIV-free survival was 81.9% (92.0% for children of RW, 58.6% for LW), 3.7% were living with HIV, 3.7% deceased, and 10.8% had unknown HIV/vital status. Being newly diagnosed with HIV at ANC enrollment was the only factor associated with becoming LTFU (aRR 1.21, 95% CI: 1.11 to 1.31). Conclusions: Outcomes among those LTFU were worse than those retained in care, underscoring the importance of retention in PVT services. Some, but not all, LW re-engaged in care by 3 years, suggesting the need for PVT services must better address the barriers and transitions women experience during pregnancy and postpartum.Item Postpartum Hepatic Infarction in Antiphospholipid Syndrome Patients(2021-03) Joseph, Sophia; Hardman, Sara; Zeh, Janie; Sivamohan, Anjali; Mehta, RakeshCASE: Our patient is a 31-year-old woman with a complicated past medical history of Systemic Lupus Erythematosus (SLE) and Antiphospholipid Ayndrome (APS). She originally presented several years ago when she was found to have Libman-Sacks endocarditis. She was diagnosed with SLE and APS at the time and was subsequently anticoagulated with warfarin. When she became pregnant, warfarin was discontinued and she was managed with a low molecular weight heparin (LMWH). She was continued on LMWH post-partum, but was noncompliant. For a few weeks following delivery, she presented to the hospital on several occasions with acute right upper quadrant pain. CT imaging confirmed several hepatic infarcts and she was treated with steroids, fondaparinux, and plaquenil. CONCLUSIONS: APS poses several risks during and after pregnancy due to susceptibility to venous and arterial thrombosis1. There is an increased risk of thrombosis up to 12 weeks postpartum. Continuation of anticoagulation following delivery is essential in APS women who have a high baseline risk of thrombosis2. Non-compliance with medications may have contributed to this presentation. This case is unique in that hepatic infarcts rarely occur due to the dual blood supply of the liver. Moreover, the diagnosis of hepatic infarction can be difficult as it may present similarly to HELLP, possibly contributing to her multiple admissions with RUQ pain3,4. CLINICAL SIGNIFICANCE: This case is significant because it demonstrates the rare, but life-threatening risk of postpartum hepatic infarction in APS patients. Proper postpartum management and compliance with anticoagulation medications are essential to mitigating risk. Furthermore, providers may face challenges in diagnosing hepatic infarction as it could mimic other diseases.
