A safe and effective use of caplacizumab in pregnancy-related acquired thrombotic thrombocytopenic purpura.

Thrombotic thrombocytopenic purpura (TTP) is not uncommonly seen in pregnancy, either with the first episode or with the exacerbation of known disease. The management of TTP in pregnancy can be challenging if there is refractoriness to the use of therapeutic plasma exchange (TPE) and high-dose corticosteroids. Caplacizumab, a vWF-directed humanized antibody fragment, is approved for the treatment of acquired TTP but there is sparse data on its use in pregnant patients. Antenatal and peripartum haemorrhage is a theoretical concern with the use of the medication in the obstetric population. However, as options for treatment of TTP in the patients who have refractory disease are significantly limited, off-label use of caplacizumab to achieve disease control and prevent maternofetal morbidity and mortality is a reasonable consideration. This article described the successful use of caplacizumab in a pregnant patient with acquired TTP and the associated favourable outcome. The patient suffered an exacerbation following initial TPE and became refractory to both plasma exchange and high-dose corticosteroids. Off-label use of caplacizumab resulted in hematologic recovery and successful delivery of a healthy neonate. This case represents a contribution to the sparse literature on the use of this effective medication in an often-challenging clinical situation.

Atrial fibrillation with rapid ventricular response as a maternal presentation of mirror syndrome: a case report.

Mirror syndrome is the phenomenon of fetal hydrops causing maternal edema and weight gain. Here, we report a case of arrhythmia as the primary maternal symptom. A 36-year-old woman, G2P1001, at 34.5 weeks of gestation presented with new-onset fetal hydrops combined with maternal weight gain and edema. She developed atrial fibrillation with rapid ventricular response; cardiac workup was unremarkable. Rate control was achieved with diltiazem. She underwent delivery and reverted to normal sinus rhythm on post-operative day 1. Volume overload causes atrial wall stress and neurohormonal changes that may trigger atrial fibrillation. Optimization with rate control facilitated good maternal and fetal outcomes in this case.

Health professional students at the University of Illinois Chicago (HOLISTIC) Cohort Study: A protocol.

OBJECTIVES: The objectives of the HOLISTIC Cohort Study are to establish a prospective cohort study covering a period of three years that characterizes the health of students within and across health professional education programs at the University of Illinois Chicago (UIC) during the coronavirus disease 2019 (COVID-19) pandemic, implement an interprofessional student research team, and generate a meaningful dataset that is used to inform initiatives that improve student health. This report describes the protocol of the HOLISTIC Cohort Study, including survey development, recruitment strategy, and data management and analysis. METHODS: An interprofessional student research team has been organized with the goal of providing continuous assessment of study design and implementation across the seven health science colleges (applied health sciences, dentistry, medicine, nursing, pharmacy, public health, and social work) at the University of Illinois Chicago in Chicago, IL. To be eligible to participate in the HOLISTIC Cohort Study, students are required to be 1) age 18 years or older; 2) enrolled full- or part-time in one or more of UIC's seven health science colleges; and 3) enrolled in a program that prepares its graduates to enter a healthcare profession. The study protocol includes a series of three recruitment waves (Spring 2021 [April 14, 2021, to May 5, 2021; completed], Spring 2022, Spring 2023). In the first recruitment wave, eligible students were sent an invitation via electronic mail (e-mail) to complete an online survey. The online survey was based on the U.S. Centers for Disease Control and Prevention's Behavioral Risk Factor Surveillance System 2019 survey and the 2014 World Health Organization Report of the Strategic Advisory Group of Experts Working Group Vaccine Hesitancy Scale. Electronic informed consent and study data are collected and managed using Research Electronic Data Capture (REDCap) tools. This study utilizes convenience sampling from all seven health science colleges at UIC with a target recruitment total of 2,000 participants. DISCUSSION AND FUTURE DIRECTIONS: A total of 555 students across all seven health science colleges (10.8% of 5,118 students who were invited; 27.6% of target sample size) enrolled in the cohort during the first recruitment wave. The pilot data establishes the feasibility of the study during the COVID-19 pandemic. Adaptations to overcome barriers to study implementation, including the use of remote, rather than in-person, study meetings, staff training, and participant recruitment are discussed. For the second and third waves of recruitment, the student research team will seek institutional review board (IRB) approval to implement additional enrollment strategies that are tailored to each health science college, such as online newsletters, virtual townhalls, flyers on bulletin boards near classrooms tailored to each health science college.

CD19 negative and dim precursor B-lineage acute lymphoblastic leukemias: real-world challenges in a targeted-immunotherapy era.

Flow cytometric diagnosis and minimal residual disease (MRD) assessment of precursor B-lineage acute lymphoblastic leukemia (B-ALL) are heavily dependent on CD19 based gating strategies. However, this approach is not optimal in the diagnosis and follow-up of CD19 negative or dim B-ALLs. Though CD19 negative B-ALLs are rare, in the current era of CD19 targeted immuno-therapy, CD19 negative B-ALL relapses are frequent. We have presented our cohort of 14 de novo CD19 negative and dim B-ALLs and have highlighted the difficulties faced during diagnosis and MRD assessment of these patients. We have also discussed the need to identify alternative B-lineage gating markers and strategies to deal with such scenarios.

Expression of Vascular Endothelial Growth Factor and Microvessel Density in Psoriatic Skin Lesions.

BACKGROUND: Psoriasis is a common chronic and immune-mediated skin disorder having a significant impact on the patient's quality of life. An analysis of the role of angiogenic vascular endothelial growth factor (VEGF) expression and microvessel density in psoriatic skin lesions may help in better understanding of the disease pathogenesis. The aim of this study was to examine the expression of vascular endothelial growth factor (VEGF) and microvessel density using CD34 antibodies in psoriatic skin lesions by immunohistochemical examination using normal skin of healthy individuals as controls. MATERIALS AND METHODS: Patients with clinical diagnosis of plaque type of psoriasis (e.g., chronic plaque) (n = 49) were included in the study. 5-mm punch biopsies were taken from the psoriatic skin lesions in these patients. A total of 20 punch biopsies were taken from the control group comprising of 20 healthy volunteers. The biopsies were subjected to histopathological examination for confirmation of diagnosis and grading. Immunohistochemical evaluation was done for the expression of VEGF, and microvessel density was assessed using CD34 and compared with the controls. RESULTS: An increased VEGF expression by keratinocytes (49.80% ± 21.16%) and microvessel density in the papillary dermis (15.302% ± 3.8061%) was observed in patients with psoriasis, which was significantly higher as compared to controls (P < 0.0001). A significant positive correlation was observed between VEGF expression by keratinocytes and the microvessel density in the dermis (r = 0.664, P = 0.01). No significant correlation was observedbetween the histopathological grade of psoriasis and microvessel density, or with the VEGF expression. CONCLUSION: VEGF expression ascertained to be a significant factor in the pathogenesis of psoriasis.

Maternal and Early Perinatal Outcomes of Triplet Pregnancy: Study of 82 Triplets from a Single Perinatal Centre in South India.

OBJECTIVES: To study the recent trends in maternal and perinatal outcomes of triplet pregnancy from a perinatal centre in South India. METHODS: All triplet pregnancies booked at Fernandez hospital, Hyderabad (a tertiary care perinatal centre in South India), or those referred between 2000 and 2014 were included in the study. The maternal, fetal and neonatal outcome and any interventions like cerclage, steroid administration were studied. RESULTS: There were 82 triplet deliveries over the study period of 15 years (82 per 69,584 live births). Most of them (78%) conceived with assistance and 83% of the triplets were trichorionic triamniotic. Anaemia and pregnancy induced hypertension were the commonest medical disorders (40.2 and 22%, respectively). Mean gestational age at delivery was 32 ± 2.8 weeks and 91% were delivered by caesarean section. Preterm labour and preterm pre-labour rupture of membranes were present in 29 and 15%, respectively. Antenatal steroids were administered in 87.8 and 53.7% had a cerclage. There were 20.7% growth restricted fetuses and 5.6% still births among the triplets. The mean birthweight among the live born neonates was 1.5 kg, and birthweight discordancy of >25% was seen in 14%. Among the live born neonates, 80% required admission to the neonatal intensive care unit, 11% had culture positive sepsis, 3% had bronchopulmonary dysplasia, and 4% died during the hospital stay. None of them had periventricular leukomalacia or retinopathy requiring LASER. Mothers in the spontaneous conception group were younger and had more monochorionic triamniotic pregnancies than in the assisted conception groups (11.8 vs. 2.9%, p = 0.001). The incidence of PPROM was significantly more in the spontaneous conception group than in the ovulation induction, intrauterine insemination groups (29.4 vs. 2.9%, p = 0.03), we do not have an explanation for this. There was no difference in the other maternal, fetal or neonatal parameters based on the mode of conception. CONCLUSION: Though triplet pregnancies are encountered infrequently, obstetricians should be familiar with their management. Appropriate antenatal, perinatal care with neonatal support can result in optimal outcome.

Study comparing 3 hour and 24 hour post-operative removal of bladder catheter and vaginal pack following vaginal surgery: a randomised controlled trial.

BACKGROUND: Traditional practice after vaginal hysterectomy was to keep the vaginal pack and urinary catheter for 24 hours post operatively. But there were studies that prolonged cathterisation was associated with urinary infection. So this study was conducted to compare the post operative outcome when the urinary catheter and vaginal pack were removed after 3 hours and after 24 hours after surgery. METHODS: The study was done in the Department of Obstetrics and Gynecology, in a tertiary teaching institute of South India from September 2008 to March 2010. It was a randomised controlled trial involving 200 women undergoing vaginal surgery, who were randomly assigned to 2 groups - catheter and vaginal pack were removed either in 3 h in study group or were removed in 24 h in control group. The outcome of the study were vaginal bleeding, urinary retention, febrile morbidity, and urinary infection. RESULTS: There was no significant difference between the study and control groups with respect to vaginal bleeding (0 and 1%, p = 1), urinary retention (9 and 4%, p = 0.15), febrile morbidity (7 and 4%, p = 0.35), and urinary infection (26% in each group, p = 1.0). CONCLUSION: Keeping the urinary catheter and vaginal pack for 24 h following vaginal surgery does not offer any additional benefit against removing them after 3 h.

Characterizing Literacy and Cognitive Function during Pregnancy and Postpartum.

Objective The objective of this study was to characterize health literacy and cognitive function in a diverse cohort of pregnant women. Methods Pregnant and postpartum women underwent in-depth assessments of health literacy/numeracy and the cognitive domains of verbal ability, working memory, long-term memory, processing speed, and inductive reasoning. Differences by demographic characteristics and gestational age were assessed using chi-square tests and multivariable logistic regression. Results In this cohort of pregnant (N = 77) or postpartum (N = 24) women, 41.6% had limited health literacy/numeracy. Women were more likely to score in the lowest quartile for literacy and verbal ability if they were less educated, younger, nonwhite or had Medicaid. These factors were associated with low scores for long-term memory, processing speed, and inductive reasoning. Although there were no differences in literacy or cognitive function by parity or gestational age, postpartum women were more likely to score in the lowest quartile for processing speed (adjusted odds ratio [aOR]: 3.79, 95% confidence interval [CI]: 1.32-10.93) and inductive reasoning (aOR: 4.07, 95% CI: 1.21-13.70). Conclusion Although postpartum status was associated with reduced inductive reasoning and processing speed, there were no differences in cognitive function across pregnancy. Practice Implications Postpartum maternal learning may require enhanced support. In addition, cognitive skills and health literacy may be a mediator of perinatal outcomes inequities.

ST-elevation acute myocardial infarction in pregnancy: 2016 update.

Acute myocardial infarction (AMI) during pregnancy or the early postpartum period is rare, but can be devastating for both the mother and the fetus. There have been major advances in the diagnosis and treatment of acute coronary syndromes in the general population, but there is little consensus on the approach to diagnosis and treatment of pregnant women. This article reviews the literature relating to the pathophysiology of AMI in pregnant patients and the challenges in diagnosis and treatment of ST-elevation myocardial infarction (STEMI) in this unique population. From a cardiologist, maternal-fetal medicine specialist, and anesthesiologist's perspective, we provide recommendations for the diagnosis and management of STEMI occurring during pregnancy.

Nutrition Recommendations in Pregnancy and Lactation.

The nutritional status of a woman during pregnancy and lactation is not only critical for her health but for future generations. Although a nutritionist or registered dietitian can help facilitate dietary counseling and interventions, physicians also need to be cognizant of nutritional needs during pregnancy because they differ significantly compared with nonpregnant populations. Furthermore, an individualized approach to nutritional counseling that considers a woman's nutritional status and body mass index is recommended.

Effect of antenatal betamethasone on blood glucose levels in women with and without diabetes.

OBJECTIVE: To characterize the maternal glycemic response to betamethasone in subjects without diabetes compared to subjects with diabetes. STUDY DESIGN: Blood glucose levels in 22 gravidae without diabetes and 11 gravidae with diabetes were recorded for 48h following betamethasone administration for threatened preterm delivery. Maximum blood glucose value and time to maximum value were compared. Area under the curve calculations were used to express the duration and degree of significant hyperglycemia for individual subjects. These summary measures were then correlated to subject characteristics and laboratory values to determine a risk profile of those subjects without diabetes at risk for significant hyperglycemia. RESULTS: All subjects with diabetes and the majority of those without diabetes had significant hyperglycemia during the study period. Mean maximum blood glucose was higher for those with diabetes (205mg/dL vs. 173mg/dL, p⩽0.01). Mean time to reach the maximum glucose level was similar for both groups. Result of a glucose tolerance test given immediately prior to betamethasone correlated strongly with amount of time spent with hyperglycemia for subjects without diabetes (rho=0.59, p⩽0.01). Morbidly obese subjects spent less time with hyperglycemia than those with lower body mass indices (p=0.03). CONCLUSION: Both subjects with and without diabetes demonstrate significant hyperglycemia after receipt of antenatal betamethasone.

How to Manage Allergic Reactions to Contrast Agent in Pregnant Patients.

OBJECTIVE: This article reviews optimal treatment of allergic reactions to iodinated contrast material in pregnant patients. Initial evaluation and treatment of a pregnant patient is similar to that for a nonpregnant patient. However, additional steps, including assessment for uterine cramping, using left uterine displacement to improve venous return, and maintaining blood pressure to ensure placental perfusion, may be required. CONCLUSION: Adequate preparation and a team approach will provide optimal care for a pregnant patient who has an allergic reaction to a contrast agent.

Low-dose rasburicase in hematologic malignancies.

OBJECTIVE: To define the efficacy and safety of low-dose rasburicase in children from south India with hematologic malignancies. METHODS: This study is a retrospective analysis of data on 41 children with hematologic malignacies with laboratory evidence of tumor lysis syndrome (TLS) or clinical features indicating high risk for developing TLS. Patients were treated with rasburicase in doses of 0.1-0.15 mg/kg dose, repeated when necessary. RESULTS: Male : Female ratio was 32:9. Thirty-six children had laboratory evidence of TLS and 5 were at risk for TLS. Diagnoses were T-cell acute lymphoblastic leukemia (ALL), 19; Pre-B ALL, 17; B-non-Hodgkin lymphoma (NHL), 2; T-NHL, 2; and acute myeloid leukemia (AML), 1. Initial plasma uric acid (PUA): median, 8.5 mg/dl (range, 4.3 to 45.5). Six had creatinine levels of >2 mg/dl on admission; and 10 had peak PO4 levels of >10 mg/dl. Dose of rasburicase used: median, 0.12 mg/kg (range, 0.08-0.24). Median reduction of PUA at 6 h: 80 % (range 40 to 98 %). Twenty-seven needed only one dose; 12 needed 2 or 3 doses; and two needed 5 doses each. One child required dialysis. None of the children developed anaphylaxis or hemolysis and there were no deaths from TLS. CONCLUSIONS: Low-dose rasburicase (0.1-0.15 mg/kg) is safe and effective in reducing PUA in Indian children with lymphoid malignancies, and thus it may reduce the risk of renal failure from TLS.

Outcomes after physical examination-indicated cerclage in twin gestations.

OBJECTIVE: To compare outcomes of physical examination-indicated cerclage in women with twin gestations to those with singleton gestations and to identify whether risk factors for extremely preterm birth (before 28 weeks) differ between these 2 groups. STUDY DESIGN: This is a single institution retrospective cohort study of women who underwent a physical examination-indicated cerclage between Jan. 1, 1980, and Aug. 15, 2012. Differences in characteristics and outcomes were compared between women with twin and singleton gestations. A multivariable analysis was performed to examine whether twin gestation was independently associated with delivery before 28 weeks and whether any effect modification was present between risk factors for preterm birth and the presence of a twin gestation. RESULTS: Of the 442 women who underwent a cerclage during the period of study, 104 (23.5%) had twins. Mean gestational age and digital cervical length at placement did not differ by plurality. Although twins were more likely to deliver at a slightly earlier median gestation than singletons (31.9 weeks; interquartile range, 24.9-35.1 vs 32.7 weeks; interquartile range, 24.6-38.3; P = .015), the frequency of delivery before 28 weeks did not differ between these 2 groups (33.7% vs 35.8%, P = .69). Greater cervical dilation and prolapsing membranes were identified as risk factors for birth <28 weeks in both groups; digital cervical length <2 cm appeared to be a risk factor particularly for women with twin gestations. CONCLUSION: Women with a twin pregnancy who received a physical examination-indicated cerclage had similar risk factors for extreme preterm birth and may experience similar obstetric outcomes as women with singleton gestations.

Pregnancy in the severely mentally ill patient as an opportunity for global coordination of care.

Although obstetricians commonly care for pregnant patients with psychiatric disorders, little has been written about the implications of managing a pregnancy during a prolonged psychiatric hospitalization for severe mental illness. Multidisciplinary care may optimize obstetric and psychiatric outcomes. We describe a severely mentally ill patient at 27 weeks' gestation (G1P0) who was admitted after a suicide attempt. She exhibited intermittently worsening depression and anxiety throughout a 2-month inpatient psychiatric hospitalization, during which her psychiatric and obstetric providers collaborated regarding her care. We review recommendations for antepartum and intrapartum treatment of the acutely suicidal and severely mentally ill patient and, in particular, the evidence that a multidisciplinary coordinated approach to planning can maximize patient physical and mental health and facilitate preparedness for delivery.

Postpartum hemorrhage: evidence-based medical interventions for prevention and treatment.

Postpartum hemorrhage (PPH) remains a significant contributor to maternal morbidity and mortality throughout the world. The majority of research on this topic has focused on efforts to prevent PPH. Sound data exist that active management of the third stage of labor can reduce the occurrence of PPH. Although there remains debate regarding the optimal protocol for active management, it appears at this time that oxytocin is the preferable uterotonic to use. Misoprostol may be a reasonable option where parenteral administration of an uterotonic is not feasible. There is little evidence to guide treatment decisions should PPH occur.

Correlation of increased fetal asymmetry with shoulder dystocia in the nondiabetic woman with suspected macrosomia.

OBJECTIVE: To determine if the sonographic difference of > or = 2.6 cm between the fetal abdominal diameter (AD) and biparietal diameter (BPD), a proxy for fetal asymmetry, has an association with shoulder dystocia in nondiabetic women with suspected macrosomia. STUDY DESIGN: A retrospective cohort study was performed in 3 Southern California tertiary care hospitals. We identified patients in whom sonographic evaluation after 36 weeks' gestation demonstrated an estimated fetal weight > 4,000 g. Additional prenatal and delivery information was obtained from hospital records. RESULTS: We identified 159 subjects who met ultrasound criteria and underwent a vaginal delivery. The mean AD-BPD difference in the shoulder dystocia group was significantly greater than in the group without shoulder dystocia (2.76 +/- 0.59 vs. 2.37 +/- 0.56, p = 0.001). The adjusted OR of shoulder dystocia in the group with an AD-BPD difference > or = 2.6 was 3.67 (95% CI, 1.44-9.36). CONCLUSION: Significant discordance between the fetal head and abdomen appears to be associated with an increased rate of shoulder dystocia in a nondiabetic population with suspected macrosomia.

Limitations of ADAMTS-13 activity level in diagnosing thrombotic thrombocytopenic purpura in pregnancy.

In pregnancy, it may be difficult to differentiate the syndrome of hemolysis, elevated liver enzymes, and low platelets from thrombotic thrombocytopenia purpura. Severely depressed (<5%) or absence of a disintegrin and metalloproteinase with thrombospondin motifs-13 activity levels are associated with thrombotic thrombocytopenia purpura and mildly decreased levels are associated with other disease processes, including pre-eclampsia and hemolysis, elevated liver enzymes, and low platelets syndrome. We present a case of a patient that presented at 20 weeks gestation with elevated liver enzymes and thrombocytopenia. The diagnosis was unclear at the time of presentation. She underwent induction of labor, and during the postpartum course, she was eventually diagnosed with thrombotic thrombocytopenia purpura; however, her activity level of a disintegrin and metalloproteinase with thrombospondin motifs-13 was only moderately depressed at 15% (normal pregnancy value 41%-105%).
