The relationship between platelet indices and hypertensive disorders of pregnancy

Griffin, Myah M; Penfield, Christina A; Hausvater, Anaïs; Schaap, Ariel; Roman, Ashley S; Xia, Yuhe; Gossett, Dana R; Quinn, Gwendolyn P; Berger, Jeffrey S
OBJECTIVE:To investigate the relationship between platelet indices (count, size and production/immaturity) and hypertensive disorders of pregnancy. STUDY DESIGN/METHODS:This was a secondary analysis of a prospective cohort of pregnant individuals followed from first trimester through delivery at an academic tertiary care institution. Routine platelet indices obtained prospectively during prenatal care and delivery were compared between those who developed a hypertensive disorder of pregnancy and those who did not. We assessed platelet count (by trimester), mean platelet volume, and immature platelet fraction measured as percent (%) and absolute count. Data were analyzed using Fisher's Exact test, chi-square test, and multivariable logistic regression. P < 0.05 was considered statistically significant. RESULTS: = 0.01) compared to those without a hypertensive disorder of pregnancy, after adjusting for age, race/ethnicity, obesity, nulliparity, and chronic hypertension. The prevalence and likelihood of a hypertensive disorder of pregnancy increased with increasing mean platelet volume, as well as with both the percent and absolute immature platelet fraction. There was no difference between groups in platelet count in the first trimester, second trimester, or at delivery. CONCLUSIONS:An increase in platelet size and immaturity was observed in those with a hypertensive disorder of pregnancy. These data support further investigation of platelets in the mechanisms of the development of hypertensive disorders of pregnancy and the use of platelet indices to better identify high risk groups in pregnancy.

A Randomized Trial of Postpartum Ibuprofen in Severe Hypertensive Disorders of Pregnancy

Penfield, Christina A; Oakes, Megan C; Caballero, Deysi; Marty, Lindsay N; Berger, Dana S; Nageotte, Michael P; Mcnulty, Jennifer A
BACKGROUND:Ibuprofen has been shown to increased blood pressure in nonpregnant adults with hypertension, but its impact on blood pressure when used for postpartum analgesia in patients with a hypertensive disorder of pregnancy is less clear, particularly for those with severe hypertension. OBJECTIVE:To evaluate the impact of ibuprofen on postpartum blood pressure outcomes in patients with hypertensive disorders of pregnancy with severe hypertension. STUDY DESIGN/METHODS:In this randomized, double-blind trial, we randomly assigned patients with hypertensive disorders of pregnancy with severe hypertension to receive a postpartum analgesic regimen with either ibuprofen 600mg or acetaminophen 650mg (control) every 6 hours. The primary outcome was severe hypertension during postpartum hospitalization. Secondary outcomes included other measures of blood pressure control such as antihypertensive medication use and average postpartum mean arterial pressure, and outpatient blood pressure as well as patient satisfaction, pain control, and diuresis. A sample size of 132 was needed to detect a 35% difference in severe postpartum hypertension. RESULTS:We enrolled 140 participants from January 2017 to October 2019. The prevalence of severe hypertension postpartum did not differ between participants receiving ibuprofen (38.6%) versus control (41.4%); the absolute difference was 2.8 percentage points, 95% confidence interval -13.1% to 18.5%, p= 0.73. There was no difference between the ibuprofen and control groups for antihypertensive medication use (35.7% versus 40.0%, p=0.60) or average postpartum mean arterial pressure (95.7+8.2 versus 95.9+9.5, p=0.91, respectively). Measures of outpatient blood pressure, patient satisfaction, diuresis, and pain control were also similar. CONCLUSION/CONCLUSIONS:In patients with hypertensive disorders of pregnancy with severe hypertension, use of ibuprofen postpartum did not increase the prevalence of postpartum severe hypertension. Ibuprofen use did not impact other blood pressure outcomes, pain control, or patient satisfaction. These findings support ibuprofen use during the postpartum period in patients with hypertensive disorders of pregnancy.

Identifying an optimal cancer risk threshold for resection of pancreatic intraductal papillary mucinous neoplasms

Sacks, Greg D; Wojtalik, Luke; Kaslow, Sarah R; Penfield, Christina A; Kang, Stella K; Hewitt, D B; Javed, Ammar A; Wolfgang, Christopher L; Braithwaite, R S
BACKGROUND:IPMN consensus guidelines make implicit judgments on what cancer risk level should prompt surgery. We used decision modeling to estimate this cancer risk threshold (CRT) for BD-IPMN patients. METHODS:We created a decision model to compare quality-adjusted life years (QALYs) following surgery or surveillance for BD-IPMNs. We simulated treatment decisions for hypothetical patients, varying age, comorbidities and lesion location (pancreatic head/tail). The base case was a 60-year-old patient with mild comorbidities and pancreatic head IPMN. Probabilities, life expectancies, and utilities were incorporated from literature/public datasets. CRT was defined as the level of cancer risk at which the expected value of QALYs for surgery first exceeded that of surveillance. RESULTS:In the base case, surgery was preferred over surveillance, yielding 21.90 vs. 21.88 QALYs. The optimal CRT for a BD-IPMN patient depended on age, comorbidities, and location. CRT in the base case was 20 % and 3 % for an IPMN in the head and tail of the pancreas, respectively. Other drivers of preferred treatment were age and likelihood of postoperative mortality. CONCLUSION/CONCLUSIONS:For BD-IPMNs, the optimal CRT varies depending on patient age and risk of surgical complications. Personalized risk threshold values could guide treatment decisions and inform future treatment consensus guidelines.

A Case of Vein of Galen Aneurysmal Malformation Diagnosed Prenatally in a Monochorionic-Diamniotic Twin Pregnancy [Case Report]

Berger, Dana Senderoff; Robinson, Andre; Chervenak, Judith; Thomas, Kristen; Srinivasan, Ranjini; Sharma, Geeta; Roman, Ashley S; Penfield, Christina A; Limaye, Meghana
We present a case of a vein of Galen aneurysmal malformation (VGAM), a rare congenital arteriovenous malformation, in one fetus of a monochorionic-diamniotic twin pregnancy. The diagnosis was made with color Doppler ultrasonography at 28 weeks and the affected fetus was found to have worsening cardiomegaly on subsequent fetal echocardiograms. She was emergently delivered at 32 weeks for abnormal fetal heart rate tracing of the affected twin. Magnetic resonance imaging of the brain findings after delivery demonstrated severe neurological injury; therefore, postnatal embolization was not performed. The neonate died on day of life 9. The cotwin survived without neurological complications. This is the first case in the literature of a VGAM diagnosed prenatally in a monochorionic-diamniotic twin pregnancy and demonstrates the challenge of delivery timing with prenatal diagnosis in a twin pregnancy.

Comparing outcomes of fetal growth restriction defined by estimated fetal weight versus isolated abdominal circumference

Griffin, Myah M; Mehta-Lee, Shilpi S; Penfield, Christina A; Roman, Ashley S
PURPOSE/OBJECTIVE:The objective of this study was to compare maternal and neonatal outcomes when the diagnosis of FGR was based on isolated abdominal circumference < 10th percentile for gestational age (GA) (iAC group) versus overall estimated fetal weight < 10th percentile (EFW group). METHODS:, and Fisher exact tests with significance defined as p < 0.05. RESULTS:635 women met the inclusion criteria, 259 women in the iAC group and 376 women in the EFW group. The iAC group was noted to have a later GA at diagnosis and delivery. iAC was associated with lower rates of preterm birth (PTB), NICU admission, SGA at delivery and umbilical artery cord gas < 7.0. CONCLUSION/CONCLUSIONS:Using iAC as a definition of FGR increased the number of FGR cases by 1.69-fold over EFW criteria alone. However, obstetrical and neonatal outcomes for the iAC group appear to be significantly better than those in the EFW group, with low rates of PTB, NICU admission, and umbilical artery cord gas < 7.0.

Association between Peripartum Mean Arterial Pressure and Postpartum Readmission for Preeclampsia with Severe Features

Lin, Bing-Xue; Smith, Maria; Sutter, Megan; Penfield, Christina A; Proudfit, Christine
OBJECTIVE: This study aimed to evaluate the relationship between peripartum mean arterial pressure (MAP) and postpartum readmission for preeclampsia with severe features. STUDY DESIGN/METHODS: This is a retrospective case-control study comparing adult parturients readmitted for preeclampsia with severe features to matched nonreadmitted controls. Our primary objective was to evaluate the association between MAP at three time points during the index hospitalization (admission, 24-hour postpartum, and discharge) and readmission risk. We also evaluated readmission risk by age, race, body mass index, and comorbidities. Our secondary aim was to establish MAP thresholds to identify the population at highest risk of readmission. Multivariate logistic regression and chi-squared tests were used to determine the adjusted odds of readmission based on MAP. Receiver operating characteristic analyses were performed to evaluate risk of readmission relative to MAP; optimal MAP thresholds were established to identify those at highest risk of readmission. Pairwise comparisons were made between subgroups after stratifying for history of hypertension, with a focus on readmitted patients with new-onset postpartum preeclampsia. RESULTS: = 0.0018) were associated with increased risk of readmission. African American race and hypertensive disorder of pregnancy were independently associated with increased risk of readmission. Subjects with MAP > 99.5 mm Hg at admission or >91.5 mm Hg at 24-hour postpartum had a risk of at least 46% of requiring postpartum readmission for preeclampsia with severe features. CONCLUSION/CONCLUSIONS: Admission and 24-hour postpartum MAP correlate with risk of postpartum readmission for preeclampsia with severe features. Evaluating MAP at these time points may be useful for identifying women at higher risk for postpartum readmission. These women may otherwise be missed based on standard clinical approaches and may benefit from heightened surveillance. KEY POINTS/CONCLUSIONS:· Existing literature focuses on management of antenatal hypertensive disorders of pregnancy.. · Elevated peripartum MAP is associated with increased odds of readmission for preeclampsia.. · Peripartum MAP may predict readmission risk for de novo postpartum preeclampsia..

Acceptance of Routine Vaccines in Pregnancy during the COVID-19 Pandemic

Perelman, Allison D; Trostle, Megan E; Pecoriello, Jillian; Quinn, Gwendolyn P; Roman, Ashley S; Penfield, Christina A
OBJECTIVE: This study aimed to evaluate the rates of vaccination against infectious diseases (Tetanus, Diphtheria, and Pertussis [Tdap] and influenza) in pregnancy during the coronavirus disease 2019 (COVID-19) pandemic compared to contemporary historical controls. STUDY DESIGN/METHODS: < 0.05. RESULTS: In total, 1,713 pregnant people were included. Compared to historical controls, the COVID cohort differed in age, race, timing of initiation of prenatal care, insurance status, and medical comorbidities. After adjusting for these covariates, pregnant people were significantly more likely to accept influenza vaccine in the COVID cohort (adjusted odds ratio [aOR] 1.7, 95% confidence interval [CI] 1.27-2.29) and had similar Tdap acceptance (aOR 1.5, 95% CI 0.99-2.17). However, this trend was not observed for the entire obstetric population; public insurance status and medical comorbidities were associated with lower vaccine rates during the pandemic. For those who had public insurance, rates of influenza vaccination decreased from 83% in 2019 to 40% during COVID (aOR 0.16, 95% CI 0.10-0.24) and for Tdap rates decreased from 93 to 54% (aOR 0.13, 95% CI 0.08-0.21). CONCLUSION/CONCLUSIONS: During the COVID-19 pandemic era, pregnant people at large were more likely to accept the influenza vaccine. However, this trend did not apply to Tdap, and high-risk groups with public insurance and medical comorbidities. This study highlights potential disparities in vaccination rates, which need to be accounted for when evaluating national vaccine trends. These data support increased efforts in vaccine counseling for high-risk populations. KEY POINTS/CONCLUSIONS:· Antenatal flu vaccination increased during the pandemic.. · Antenatal Tdap vaccination was unchanged during the pandemic.. · High-risk pregnant patients had decreased vaccine uptake.. · High-risk subgroups were not included in overarching vaccination trends..

Decision-making for congenital anomalies diagnosed during pregnancy: a narrative review

Pecoriello, Jillian; Lilly, Anna- Grace; Jalili, Dona; Mendoza, Clarisa; Quinn, Gwendolyn P; Penfield, Christina A
PURPOSE/OBJECTIVE:The purpose of this narrative review was to assess the limited literature on fetal anomalies diagnosed in the second trimester of pregnancy and parental decision-making and identify sources of information deemed as facilitators and barriers to medical decisions. METHODS:This was a literature review of source material and information about fetal anomalies diagnosed in the second trimester of pregnancy, decision-making, decision tools or aids, and sources of information for anomalies. The search string used explored related peer-reviewed publications and systematic reviews between 2007 and 2024. We also reviewed references from publications meeting inclusion criteria. The search was conducted between June 2022 and February 2024. Exclusion criteria included conference abstracts, non-peer reviewed literature, and articles not available in English language. A total of 77 publications were identified by searching multiple databases using a predefined search string. The search encompassed full text articles from 2007 to 2024 and 11 full-text publications were ultimately included in the review. A list of 45 co-occurring keywords was generated from the included texts, with each keyword having a minimum of two co-occurrences. RESULTS:Key themes identified included (1) the role of the clinician and need for development of professional knowledge and empathy surrounding discussion of fetal anomalies with patients; (2) information gathering, with individuals reporting use of multiple strategies to obtain information; while the majority found information satisfying, they preferred more details on diagnosis, long-term outcomes of the fetus/child and management of the pregnancy or termination process; and (3) decision-making, the path and process of how individuals made decisions about the pregnancy including quality of life, future fertility, and seeking other people's experiences. CONCLUSION/CONCLUSIONS:Many factors contribute to an individual's decision-making after a diagnosis of a fetal anomalies diagnosed in the second trimester of pregnancy, ranging from personal beliefs and goals to shared experiences of others and access to care. Understanding how sources of information may be deemed both as facilitators and barriers to different individuals during the decision-making process is important for healthcare providers in order to understand how to most effectively support patients. There is a dearth of information on training healthcare professionals to provide support to patients facing these decisions.
