Systolic Hypertension, Preeclampsia-Related Mortality, and Stroke in California. Obstetrics and gynecology 2019; 133 (6): 115159
Abstract
OBJECTIVE: To describe the clinical characteristics of stroke and opportunities to improve care in a cohort of preeclampsia-related maternal mortalities in California.METHODS: The California Pregnancy-Associated Mortality Review retrospectively examined a cohort of preeclampsia pregnancy-related deaths in California from 2002 to 2007. Stroke cases were identified among preeclampsia deaths, and case summaries were reviewed with attention to clinical variables, particularly hypertension. Health care provider- and patient-related contributing factors were also examined.RESULTS: Among 54 preeclampsia pregnancy-related deaths that occurred in California from 2002 to 2007, 33 were attributed to stroke. Systolic blood pressure exceeded 160 mm Hg in 96% of cases, and diastolic blood pressure was 110 or higher in 65% of cases. Hemolysis, elevated liver enzymes, and low platelet count syndrome was present in 38% (9/24) of cases with available laboratory data; eclampsia occurred in 36% of cases. Headache was the most frequent symptom (87%) preceding stroke. Elevated liver transaminases were the most common laboratory abnormality (71%). Only 48% of women received antihypertensive treatment. A good-to-strong chance to alter outcome was identified in stroke cases 66% (21/32), with delayed response to clinical warning signs in 91% (30/33) of cases and ineffective treatment in 76% (25/33) cases being the most common areas for improvement.CONCLUSION: Stroke is the major cause of maternal mortality associated with preeclampsia or eclampsia. All but one patient in this series of strokes demonstrated severe elevation of systolic blood pressure, whereas other variables were less consistently observed. Antihypertensive treatment was not implemented in the majority of cases. Opportunities for care improvement exist and may significantly affect maternal mortality.

Differential Dynamics of the Maternal Immune System in Healthy Pregnancy and Preeclampsia. Frontiers in immunology 2019; 10: 1305
Abstract
Preeclampsia is one of the most severe pregnancy complications and a leading cause of maternal death. However, early diagnosis of preeclampsia remains a clinical challenge. Alterations in the normal immune adaptations necessary for the maintenance of a healthy pregnancy are central features of preeclampsia. However, prior analyses primarily focused on the static assessment of select immune cell subsets have provided limited information for the prediction of preeclampsia. Here, we used a high-dimensional mass cytometry immunoassay to characterize the dynamic changes of over 370 immune cell features (including cell distribution and functional responses) in maternal blood during healthy and preeclamptic pregnancies. We found a set of eight cell-specific immune features that accurately identified patients well before the clinical diagnosis of preeclampsia (median area under the curve (AUC) 0.91, interquartile range [0.82-0.92]). Several features recapitulated previously known immune dysfunctions in preeclampsia, such as elevated pro-inflammatory innate immune responses early in pregnancy and impaired regulatory T (Treg) cell signaling. The analysis revealed additional novel immune responses that were strongly associated with, and preceded the onset of preeclampsia, notably abnormal STAT5ab signaling dynamics in CD4+T cell subsets (AUC 0.92, p = 8.0E-5). These results provide a global readout of the dynamics of the maternal immune system early in pregnancy and lay the groundwork for identifying clinically-relevant immune dysfunctions for the prediction and prevention of preeclampsia.

Development of the TeamOBS-PPH - targeting clinical performance in postpartum hemorrhage ACTA OBSTETRICIA ET GYNECOLOGICA SCANDINAVICA 2018; 97 (6): 67787
Abstract
This study aimed to develop a valid and reliable TeamOBS-PPH tool for assessing clinical performance in the management of postpartum hemorrhage (PPH). The tool was evaluated using video-recordings of teams managing PPH in both real-life and simulated settings.A Delphi panel consisting of 12 obstetricians from the UK, Norway, Sweden, Iceland, and Denmark achieved consensus on (i) the elements to include in the assessment tool, (ii) the weighting of each element, and (iii) the final tool. The validity and reliability were evaluated according to Cook and Beckman. (Level 1) Four raters scored four video-recordings of in situ simulations of PPH. (Level 2) Two raters scored 85 video-recordings of real-life teams managing patients with PPH 1000 mL in two Danish hospitals. (Level 3) Two raters scored 15 video-recordings of in situ simulations of PPH from a US hospital.The tool was designed with scores from 0 to 100. (Level 1) Teams of novices had a median score of 54 (95% CI 48-60), whereas experienced teams had a median score of 75 (95% CI 71-79; p < 0.001). (Level 2) The intra-rater [intra-class correlation (ICC) = 0.96] and inter-rater (ICC = 0.83) agreements for real-life PPH were strong. The tool was applicable in all cases: atony, retained placenta, and lacerations. (Level 3) The tool was easily adapted to in situ simulation settings in the USA (ICC = 0.86).The TeamOBS-PPH tool appears to be valid and reliable for assessing clinical performance in real-life and simulated settings. The tool will be shared as the free TeamOBS App.

Disseminated Intravascular Coagulation Complicating the Conservative Management of Placenta Percreta OBSTETRICS AND GYNECOLOGY 2015; 126 (5): 1016-1018
Abstract
Retention of the placenta is an option in the management of placenta percreta; however, it may be associated with significant morbidity.We present a case of conservative management of placenta percreta. Disseminated intravascular coagulation (DIC) developed 49 days after delivery. An urgent hysterectomy was performed, followed by rapid normalization of coagulation parameters.Disseminated intravascular coagulation may complicate the conservative management of placenta percreta and can manifest weeks after delivery in the absence of antecedent hemorrhage or infection. The time course and presentation of this case are similar to the development of DIC after prolonged retention of a fetal demise with a probable shared pathophysiology. Close follow-up may facilitate prompt diagnosis of DIC, thereby minimizing associated morbidity.
