Postpartum care: Discussions and counseling for the peripartum period.

BACKGROUND: Traditionally, postpartum care is confined to inpatient care immediately post birth and one appointment approximately six weeks postpartum. Data supports a continuum of care model as best for the health of mother and baby. Despite most women having significant concerns about the postpartum period, these concerns are frequently incompletely addressed by providers. We surveyed prenatal and postpartum patients to understand their concerns and experiences discussing postpartum care with providers. METHODS: Cross sectional surveys were administered between June 2019 and May 2021. Principal component analysis was used to show higher than average (positive) or lower than average (negative) conversations with providers about postpartum care examined by race, education, and parity. Chi squared tests were conducted to examine the significance of specific postpartum concerns. RESULTS: 421/450 patient surveys were analyzed, based on completion. Most patients were White (193), had post graduate degrees (188), privately insured (236), married (248), first time pregnant (152), and used doctors as their primary provider (267). Patients with lower education, higher parity and Black patients without postgraduate degrees reported higher than average postpartum counseling. Additionally, most patients expressed significant concerns about postpartum exhaustion (65.8%), breastfeeding (62.3%), pain (61.2%), physical activity (54.9%) and the baby blues (50.4%). CONCLUSIONS: Postpartum concerns are incompletely and inconsistently addressed amongst patients based on race, parity, and education. A continuum of care approach, beginning in the third trimester, through the postpartum period, may provide better counseling to address all patients' concerns.

Predicting risk of peripartum blood transfusion during vaginal and cesarean delivery: A risk prediction model.

OBJECTIVE: The objective of this study is to develop a model that will help predict the risk of blood transfusion using information available prior to delivery. STUDY DESIGN: The study is a secondary analysis of the Consortium on Safe Labor registry. Women who had a delivery from 2002 to 2008 were included. Pre-delivery variables that had significant associations with transfusion were included in a multivariable logistic regression model predicting transfusion. The prediction model was internally validated using randomly selected samples from the same population of women. RESULTS: Of 156,572 deliveries, 5,463 deliveries (3.5%) required transfusion. Women who had deliveries requiring transfusion were more likely to have a number of comorbidities such as preeclampsia (6.3% versus 4.1%, OR 1.21, 95% CI 1.08-1.36), placenta previa (1.8% versus 0.4%, OR 4.11, 95% CI 3.25-5.21) and anemia (10.6% versus 5.4%, OR 1.30, 95% CI 1.21-1.41). Transfusion was least likely to occur in university teaching hospitals compared to community hospitals. The c statistic was 0.71 (95% CI 0.70-0.72) in the derivation sample. The most salient predictors of transfusion included type of hospital, placenta previa, multiple gestations, diabetes mellitus, anemia, asthma, previous births, preeclampsia, type of insurance, age, gestational age, and vertex presentation. The model was well-calibrated and showed strong internal validation. CONCLUSION: The model identified independent risk factors that can help predict the risk of transfusion prior to delivery. If externally validated in another dataset, this model can assist health care professionals counsel patients and prepare facilities/resources to reduce maternal morbidity.

Practices of sickle cell disease genetic screening and testing in the prenatal population.

BACKGROUND: Genetic screening and testing are technologies historically underutilized in Black populations despite predicting diseases like sickle cell disease (SCD), which is predominantly found in Blacks. We surveyed prenatal patients to understand choices, beliefs and experiences surrounding genetic screening and testing, specifically for SCD. METHODS: In this cross-sectional study, we surveyed 322 women during prenatal visits. Responses were analyzed to identify barriers to care and education about testing and screening for SCD. Patients rated whether they agreed or disagreed with statements regarding sickle cell health behaviors. We used χ2 tests to compare categorical variables by self-reported race. Binary logistic regression was used to determine the odds ratios and confidence intervals for each outcome. RESULTS: Women were a mean (SD) age of 33.3 (6.1). 42.9% of patients self-identified as White while 41.3% of patients self- identified as Black. Screening questions were adjusted for differences in race, insurance, and education levels to show significant differences in responses between Blacks and Whites for screening for SCD (p = 0.047, OR 95% CI = 0.455 [0.210-0.989]) and plans to meet with genetic counselors (p = 0.049, OR 95% CI = 0.299 [0.090-0.993]). The statements "if sickle cell is not in their family, then it is likely not in themselves or their children," was significantly different between Black and White populations (p = 0.011, OR 95% CI = 0.207 [0.081-0.526]). CONCLUSION: Our findings suggest gaps in screening, testing, education, and pregnancy management choices between Black and White patients. Research should focus on decreasing these healthcare gaps and improving education that address concerns about SCD for relevant populations.

Outcomes of intubation and endoscopic DCR in functional nasolacrimal duct obstruction.

BACKGROUND: To ascertain the success of lacrimal intubation and DCR in alleviating epiphora due to functional nasolacrimal duct obstruction (FNLDO). METHODS: Consecutive adult patients with epiphora attending a tertiary lacrimal clinic from May 2010 to February 2021 were reviewed to identify cases with FNLDO. FNLDO was defined as epiphora with the exclusion of alternate causes of watering on clinical examination, patent lacrimal syringing, normal DCG, and post-sac delay on DSG. Epiphora resolution and improvement rates in FNLDO were compared between lacrimal intubation and endo-DCR. RESULTS: 23 endo-DCRs (20 patients, 65% females, mean age 68.9±12.2) and 41 intubations (29 patients, 61.2% females, mean age 65.0±14.1) performed in FNLDO were included. Resolution of epiphora was achieved in 15 of the DCR procedures (median follow-up 9 months) compared to 14 of intubations (median follow-up 10 months). Significant epiphora improvement (i.e., either improvement or resolution) was noted in 21 DCRs and 24 intubations. Seven patients undergoing intubation as the primary procedure had endo-DCR performed following the intubation. Among respondents to a phone questionnaire, 53.8% who had endo-DCR (median 69 months) and 50% that had intubation (median 28 months) reported significant improvement in epiphora. CONCLUSIONS: Improvement in epiphora due to FNLDO was approximately 59% in intubations, while the success of endo-DCR was higher (91%). The long-term results of these interventions warrant further investigation.

Addison's disease in pregnancy: Case report, management, and review of the literature.

BACKGROUND: Addison's disease is an uncommon condition encountered during pregnancy; however, pregnant patients with Addison's disease are at higher risk for multiple pregnancy related complications. Treatment during pregnancy involves steroid replacement therapy. CASE REPORT: A 34-year-old previously healthy G2P1001 presented with lethargy, skin hyperpigmentation, polyuria, and salt craving. Laboratory evaluation showed hyperkalemia, hyponatremia, elevated ACTH, and low cortisol. The patient terminated the pregnancy due to her symptoms. She was then placed on a regimen of hydrocortisone and fludrocortisone, leading to symptom resolution. On second presentation as a G5P1031, her Addison's disease was managed with hydrocortisone and fludrocortisone. When Addison's symptoms recurred, ACTH levels were checked to determine if her current medications could be optimized. She ultimately delivered a healthy male infant vaginally. For her third presentation as a G6P2032, her pregnancy was managed in a similar manner to the previous pregnancy. CONCLUSION: There is currently minimal cohesive literature on the management of Addison's disease during pregnancy. Patients can be managed successfully by monitoring for recurrence of Addison's symptoms and adjusting medication dosing as needed.

Whole-exome sequencing for diagnosis of Peters-plus syndrome after prenatal diagnosis of recurrent low PAPP-A and multiple fetal anomalies in two consecutive pregnancies.

 We report a case of two consecutive pregnancies in the same couple presenting with very low pregnancy-associated plasma protein A (PAPP-A), with both pregnancies affected by multiple anomalies of a similar phenotype identified during mid-trimester ultrasound, and eventual diagnosis of Peters-plus syndrome. This case is important in expanding the differential for very low PAPP-A. It also demonstrates the diagnostic value of whole-exome sequencing (WES) after prenatal diagnosis of recurrent fetal ultrasonographic findings. The importance and complexity of providing patient education to enable informed consent for next generation sequencing technologies is discussed.

Active Subjects With Autoimmune Type 1 Diabetes Have Better Metabolic Profiles Than Sedentary Controls.

Previous studies in humans with type 1 diabetes mellitus (T1D) and in nonobese diabetic mice have investigated the beneficial immunomodulatory potential of aerobic physical activity. Performing high volume of aerobic exercise may favorably regulate autoimmunity in diabetes. We tested whether increased physical activity is a self-sufficient positive factor in T1D subjects. During a 3-month observational period, active (six males; 40.5 ± 6.1 years; BMI: 24.5 ± 2.1) and sedentary (four males, three females; 35.9 ± 8.9 years; BMI: 25.7 ± 3.8) T1D individuals on insulin pump therapy were studied for metabolic, inflammatory, and autoimmune parameters. At baseline and at the end of a 3-month period, glycosylated hemoglobin (HbA1c), autoantibodies (anti-GAD, anti-ZnT8, anti-IA2, and ICA) and proinflammatory cytokines (IL-6 and TNF-α) were evaluated. During the third month of the period, physically active T1D patients showed a significant reduction in the average glucose levels (-9%, p = 0.025, by CGM) compared to the first month values, and even their hyperglycemic episodes (>180 mg/dl) diminished significantly (-24.2%, p = 0.032 vs. first month). Moreover, active T1D subjects exhibited an improved body composition with respect to sedentary controls. No significant changes were detected as to the autoimmune and inflammatory profiles. This study confirms the beneficial role of physical exercise associated with insulin pump therapy in order to improve metabolic control in individuals with T1D. These preliminary positive observations need to be challenged in a prolonged interventional follow-up.

Moyamoya disease in pregnancy: management after intracranial bypass grafting.

Moyamoya disease (MD) is a chronic, progressive cerebrovascular disease distinguished by bilateral stenosis or occlusion of the arteries around the circle of Willis with resulting prominent arterial collateral circulation. We describe a pregnant woman in whom this diagnosis was confirmed by cerebral angiogram and treated with bilateral superficial temporal artery-middle cerebral artery (STA-MCA) bypass grafting prior to conception. The patient was managed with strict blood pressure monitoring and low-dose aspirin antepartum, intrapartum, and postpartum. The patient presented in spontaneous labor at term and underwent a spontaneous vaginal delivery without complications.

Effects of the food contaminant semicarbazide following oral administration in juvenile Sprague-Dawley rats.

Semicarbazide (SEM) is an azodicarbonamide by-product present in glass jar packaged foods including babyfoods, in bleaching steps and flour treatment. Experimental data showed SEM acting as osteolathyrogen agent, but few toxicological data are available in susceptible life-stages. This study aimed to evaluate effects of SEM oral administration for 28 days at 0, 40, 75, 140 mg/kg bw day during the juvenile period in Sprague-Dawley rats. Histopatological examinations of: epiphyseal cartilage - potential target of SEM lathyrogen action - testes, ovary, uterus, thyroid, thymus, spleen, adrenals, representative of the main developing organs relevant to juvenile toxicity, and neurobehavioural tests in males, were performed. Mortality at high and mid dose levels and significantly decreased body weight gain were observed in males even at the lowest dose. Lack of mineralization in cartilage at all dose levels was present. Marked alterations of spontaneous motor and exploratory behaviours were evident even at 40 mg/kg. Histological alterations were observed in all tissues; thyroid and ovary effects were present also at 40 mg/kg. The present study indicate that the NOAEL in juvenile rats is lower than 40 mg/kg for SEM oral administration. SEM administration during juvenile period exerted pleiotropic effects and further studies are suggested to elucidate mechanisms.

1,2-Dimethylhydrazine-induced colon carcinoma and lymphoma in msh2(-/-) mice.

BACKGROUND: Defective mismatch repair (MMR) in humans is particularly associated with familial colorectal cancer, but defective repair in mice is generally associated with lymphoma in the absence of experimental exposure to carcinogens. Loss of MMR also confers resistance to the toxic effects of methylating agents. We investigated whether resistance to methylation contributes to increased susceptibility to colorectal cancer in mice by exposing mice with defects in the MMR gene msh2 to a methylating agent. METHODS: Tumor incidence and time of death in msh2(+/+), msh2(+/-), and msh2(-/-) mice were analyzed after weekly exposure (until tumor appearance) to the methylating agent 1,2-dimethylhydrazine (DMH). Chemically induced and spontaneous tumors were characterized by frequency, type, and location. The tumor incidence in untreated and treated mice of each genotype was compared by a Mann-Whitney U test. Carcinogen-induced apoptosis in histologic sections of small and large intestines was also determined. All statistical tests were two-sided. RESULTS: Homozygous inactivation of the msh2 gene statistically significantly accelerated (P<.0001) death due to the development of DMH-induced colorectal tumors and lymphomas. Rates of death from DMH-induced colorectal adenocarcinoma were similar in msh2 heterozygous and wild-type mice, but only msh2 heterozygotes (msh(+/-)) developed additional, noncolorectal malignancies (notably trichofolliculoma [two of 21], angiosarcoma of the kidney capsule [two of 21], and lymphoma [one of 21]), suggesting that heterozygosity for msh2 slightly increases DMH susceptibility. DMH induced apoptosis in small intestinal and colonic epithelial crypts that was dependent on active msh2. CONCLUSIONS: Inactivation of msh2 allows the proliferation of gastrointestinal tract cells damaged by methylating agents. Furthermore, MMR constitutes a powerful defense against colorectal cancer induced by DNA methylation.

Equal care ensures equal survival for African-American women with cervical carcinoma.

BACKGROUND: [corrected] It was the purpose of this study to investigate whether race is an independent prognostic factor in the survival of patients with cervical carcinoma in a health care system with minimal racial bias, and few barriers to access to care. METHODS: Records for patients with a diagnosis of invasive cervical carcinoma from 1988 to 1999 were obtained from the Automated Central Tumor Registry for the United States Military Health Care System. Clinical data including race, age at diagnosis, histology, grade, stage, socioeconomic status, treatment modality, and survival also were obtained. Survival analysis was performed with Kaplan-Meier survival curves. RESULTS: One thousand five hundred fifty-three patients were obtained for review. Sixty-five percent of patients were Caucasian, and 35% were minorities. Of the minorities, 29% were African Americans (AAs). Mean age of diagnosis was similar among AAs and Caucasians, 44 and 42 years, respectively. There was no statistically significant difference between the distribution of age, stage, grade, or histology between Caucasians and AAs. Forty-six percent of patients were treated with surgery and 56% with radiation therapy, with no difference in type of treatment between the Caucasian and AA groups. Five- and 10-year survival rates for Caucasians and AAs were 75%, and 76%, and 64% 65% (P = 0.59), respectively. CONCLUSIONS: In an equal access, unbiased, nonracial environment, race is not an independent predictor of survival for patients with cervical carcinoma. This study has shown, for the first time to the authors' knowledge, that when they receive equal treatment for cervical carcinoma, AA women's survival can approach that of their nonminority counterparts (75% at 10 years).

Laboratory testing for preeclampsia: result trends and screening recommendations.

To better direct screening for preeclampsia, we describe the result trends of the laboratory tests used in the workup of preeclampsia at our institution. The clinical characteristics of patients with abnormal test results are further detailed. The objective of the study is to recommend a laboratory screening regimen for preeclampsia based on the data. All patients who delivered at National Naval Medical Center from February to July 1996 who had blood urea nitrogen, creatinine, aspartate aminotransferase, alanine aminotransferase, or uric acid determinations as part of a workup for preeclampsia were identified. Results are reported, and the clinical characteristics of patients with abnormal tests were obtained from the medical record. Abnormalities of uric acid and liver enzymes were few in our patient population (6% and 7%, respectively). The majority of patients with abnormal uric acid and liver function tests had the classic clinical symptoms of preeclampsia; therefore, the laboratory data added little to the clinical diagnosis. There was a high rate of renal test abnormalities, necessitating further investigation. We recommend omitting liver function and uric acid testing in the routine screening for preeclampsia. The high incidence of abnormal renal tests warrants continued use of this screening test and, more importantly, further investigation into the relationship between abnormal renal tests and disease course.

Effect of meconium on the hemoglobin-oxygen association curve.

OBJECTIVE: Our purpose was to determine the effect of meconium-stained amniotic fluid on the hemoglobin-oxygen association curve of maternal whole blood. METHODS: Whole blood was obtained from term gravidas in active labor. Hemoglobin-oxygen association curves were generated for blood incubated with meconium vs. controls. Oxygen association curves were determined at pH 7.4 and 37 degrees C utilizing an automated device consisting of a spectrophotometer cuvette fitted with a magnetic stirrer, gas exchange line, and a Clark oxygen electrode. The samples were deoxygenated with nitrogen and association curves recorded while reoxygenating. Data was analyzed with Sigma Plot and Sigma Stat software. Analysis included log transformation, linear regression, and paired t-test. RESULTS: Twenty-eight hemoglobin oxygen association curves were generated. In all 14 pairs, meconium shifted the hemoglobin-oxygen association curve to the right. Partial pressures of oxygen required for various degrees of hemoglobin saturation were higher in meconium-exposed samples; P50 (30.1+/-0.6 vs. 27.8+/-0.4 mmHg, P < 0.01); P75 (46.9+/-0.6 vs. 43.1+/-0.5 mmHg, P < .001); P90 (69.2+/-1 vs. 63.3+/-1 mmHg, P < 0.01). CONCLUSIONS: Meconium-stained amniotic fluid causes a statistically significant, but clinically small, right shift in the hemoglobin-oxygen association curve.

Isolated bilateral anophthalmia in a girl with an apparently balanced de novo translocation: 46,XX,t(3;11)(q27;p11.2).

Primary anophthalmos is a heterogeneous condition. In its nonsyndromal form, it is usually considered an autosomal recessive trait. However, other causes such as chromosomal abnormalities and prenatal insults need to be considered. We report on a unique reciprocal translocation 46,XX,t(3;11)(q27;p11.2) in a baby with isolated anophthalmos. Both Chitayat et al. [1996] and Alvarez Arratia et al. [1984] have reported on cases of terminal deletion of the long arm of chromosome 3. In each case the child had multiple anomalies including microphthalmia or anophthalmia. Because our patient appears to have no other anomalies, this break point may indicate that a genetic locus for eye formation exists at chromosome site 3q27. Published 1999 Wiley-Liss, Inc.

Problems in testing and risk assessment of endocrine disrupting chemicals with regard to developmental toxicology.

Endocrine disrupting chemicals (EDCs) may affect mammalian development either indirectly (by impairing implantation, placental development, lactation, etc.) or directly, altering the maturation of target tissues. Current regulatory tests for reproductive/developmental toxicity should be carefully evaluated with regard to risk assessment of EDCs, considering hazard identification (are relevant endpoints being assessed?) and dose-response assessment (are sensitive NOEL/dose-response curves being provided?). Many in vitro and in vivo assays for sex steroid disruption are available; provided that the metabolic capacities of the assays are defined, they could be integrated in a sensitive battery for early detection of steroid-disrupting potentials. The screening battery should address further regulatory in vivo tests (e.g. what specific parameters have to be investigated). As regards dose-response, qualitative differences may be observed between lower and higher exposures, showing primary hormone-related effects and frank embryotoxicity, respectively. Other problems concern (a) the identification of critical developmental windows, according to hormone concentrations and/or receptor levels in the developing target tissues; (b) the potential for interactions between chemicals with common mechanism/target (e.g. xenoestrogens); (c) most important, besides sex steroids more attention should be given to other mechanisms of endocrine disruption, e.g., thyroid effects, which can be highly relevant to prenatal and postnatal development.

Activity of nine fluoroquinolones against strains of Bordetella bronchiseptica.

Thirty-two strains of Bordetella bronchiseptica were tested for their antimicrobial susceptibilities to nine fluoroquinolones. The most active agents were fleroxacin, temafloxacin, ciprofloxacin (MIC90 1 microg/ml), ofloxacin, lomefloxacin and enoxacin (MIC90 2 microg/ml). Pefloxacin and norfloxacin were active only against 59.3 and 83.1%, respectively, of the strains tested, whereas rufloxacin lacked activity against all the strains of B. bronchiseptica tested.

Asymptomatic intussusception of the appendix due to endometriosis.

We present the case of a 29-year-old woman with an asymptomatic intussuscepted appendix found incidentally during surgical evaluation for a pelvic mass in a patient with endometriosis. This case represents the rare nature of this presentation and the need to fully evaluate the gastrointestinal tract in patients with endometriosis.

Impact of genetic counseling on primary and preventive care in obstetrics and gynecology.

OBJECTIVE: To evaluate the utility of the prenatal three-generation pedigree in assessment of the obstetric patient's primary medical risks. STUDY DESIGN: In a case series, 250 charts of patients referred for amniocentesis on the basis of advanced maternal age were reviewed for a significant genetic risk of a primary care disorder. RESULTS: A total of 40 patients (16%) were at significantly increased risk for a primary care disorder. Thirty-eight patients (15.2%) were at increased risk for medical conditions for which early screening, detection and/or intervention are established. CONCLUSION: For the advanced maternal age population, formal genetic risk assessment performed prior to amniocentesis can be beneficial in primary care risk assessment.
