We aimed to identify predictive markers of peri- and postpartum disorders in dairy cows. Data regarding peri- and postpartum disorders, serum metabolites, body condition score (BCS), and rectal temperature, were collected from 227 dairy cows, which were allocated to healthy (n = 57) and diseased (n = 170) groups. Serum non-esterified fatty acid (NEFA) concentration was higher in diseased than healthy cows 4 weeks before (p < 0.01) and immediately after (p = 0.05) calving. Serum alanine aminotransferase (AST) activity was higher (p < 0.05) in diseased than healthy cows 1 and 2 weeks after calving, whereas total cholesterol (TCH) concentration was lower (p < 0.05–0.0001) in diseased cows 4 weeks before, and after calving. BCS was higher (p < 0.05) in diseased than healthy cows 4 weeks before calving, but lower (p < 0.01) in diseased cows 8 weeks after calving. Rectal temperature was higher (p < 0.05–0.01) in diseased than healthy cows between 2 and 14 days postpartum. In conclusion, high serum NEFA and AST concentrations and lower TCH concentration during the peripartum period, and high prepartum BCS and postpartum rectal temperature, could be used as biomarkers to predict the subsequent development of peri- and postpartum disorders.

OBJECTIVES: To report our experiences in pregnant patients with pulmonary arterial hypertension (PAH) who were treated with targeted therapy. METHODS: From 2011 to 2017, women who decided to maintain pregnancies in our PAH clinic were included. Clinical data, management, and outcomes of the mothers and fetuses were reviewed. RESULTS: Nine women with PAH and 10 deliveries were reviewed. The median maternal age was 28 (26–32) years old. The functional status of each patient was New York Heart Association functional class II or III at first visit. Sildenafil was prescribed in advance in 9 cases of delivery. Multidiscipline team approach management and intensive care were performed during the peripartum period. There was no maternal or fetal mortality. Severe cardiac events occurred in 2 patients with Eisenmenger syndrome: cardiac arrest and uncontrolled arrhythmia. Non-cardiac events occurred in 3 cases: postpartum bleeding, urinary tract infection, and pneumonia. The median gestational period at delivery was about 34 (32–38) weeks. Three cases were emergent delivery because of unexpected preterm labor. Intrauterine growth restriction developed in 4 fetuses. CONCLUSIONS: Pregnancy could be maintained by the introduction of targeted therapy rather more safely than the previous era in the case of maintenance of pregnancy. Intensive care and a multidisciplinary team approach can possibly improve the outcomes of the pregnant women with PAH and their babies. However, pregnancy in patients with PAH is still strongly prohibited and it can be tried in expert center where there has sufficient multidisciplinary team approach in case of inevitability.

BACKGROUND: Obstetric patients with placenta previa are at risk for sever peripartum hemorrhage. Early detection of anemia and proper transfusion strategy are important for the management of obstetric hemorrhage. In this study, we assessed the utility and accuracy of noninvasive hemoglobin (SpHb) monitoring in patients with placenta previa during cesarean section.METHODS: Parturients diagnosed with placenta previa and scheduled for cesarean section under spinal anesthesia were enrolled. SpHb and laboratory Hb (Lab-Hb) were measured during surgery as primary outcomes.RESULTS: Seventy-four pairs of SpHb and Lab-Hb were collected from 39 patients. The correlation coefficient was 0.877 between SpHb and Lab-Hb (P < 0.001). The Bland-Altman plot showed a mean difference ± SD of 0.3 ± 0.8 g/dl between noninvasive Hb and Lab-Hb, and the limits of agreement were −1.2 to 1.8 g/dl. The magnitude of the difference between SpHb and Lab-Hb was < 0.5 g/dl in 64.9%; however, it was > 1.5 g/dl in 10.8%.CONCLUSIONS: SpHb monitoring had a good correlation with Lab-Hb. A small mean difference between SpHb and lab-Hb might not be clinically significant; however, the limits of agreements were not narrow. In particular, SpHb could be overestimated in the anemic population. Based on our results, further studies investigating the accuracy and precision of SpHb monitoring should be performed in parturients presenting Hb below 10 g/dl.

4.Adult Congenital Heart Disease with Pregnancy
Korean Circulation Journal 2018;48(4):251-276
The number of women with congenital heart disease (CHD) at risk of pregnancy is growing because over 90% of them are grown-up into adulthood. The outcome of pregnancy and delivery is favorable in most of them provided that functional class and systemic ventricular function are good. Women with CHD such as pulmonary hypertension (Eisenmenger syndrome), severe left ventricular outflow stenosis, cyanotic CHD, aortopathy, Fontan procedure and systemic right ventricle (complete transposition of the great arteries [TGA] after atrial switch, congenitally corrected TGA) carry a high-risk. Most frequent complications during pregnancy and delivery are heart failure, arrhythmias, bleeding or thrombosis, and rarely maternal death. Complications of fetus are prematurity, low birth weight, abortion, and stillbirth. Risk stratification of pregnancy and delivery relates to functional status of the patient and is lesion specific. Medication during pregnancy and post-delivery (breast feeding) is a big concern. Especially prescribing medication with teratogenicity should be avoidable. Adequate care during pregnancy, delivery, and the postpartum period requires a multidisciplinary team approach with cardiologists, obstetricians, anesthesiologists, neonatologists, nurses and other related disciplines. Caring for a baby is an important issue due to temporarily pregnancy-induced cardiac dysfunction, and therefore familial support is mandatory especially during peripartum and after delivery. Timely pre-pregnancy counseling should be offered to all women with CHD to prevent avoidable pregnancy-related risks. Successful pregnancy is feasible for most women with CHD at relatively low risk when appropriate counseling and optimal care are provided.

5.Unsettled Issues and Future Directions for Research on Cardiovascular Diseases in Women
Korean Circulation Journal 2018;48(9):792-812
Biological sex (being female or male) significantly influences the course of disease. This simple fact must be considered in all cardiovascular diagnosis and therapy. However, major gaps in knowledge about and awareness of cardiovascular disease in women still impede the implementation of sex-specific strategies. Among the gaps are a lack of understanding of the pathophysiology of women-biased coronary artery disease syndromes (spasms, dissections, Takotsubo syndrome), sex differences in cardiomyopathies and heart failure, a higher prevalence of cardiomyopathies with sarcomeric mutations in men, a higher prevalence of heart failure with preserved ejection fraction in women, and sex-specific disease mechanisms, as well as sex differences in sudden cardiac arrest and long QT syndrome. Basic research strategies must do more to include female-specific aspects of disease such as the genetic imbalance of 2 versus one X chromosome and the effects of sex hormones. Drug therapy in women also needs more attention. Furthermore, pregnancy-associated cardiovascular disease must be considered a potential risk factor in women, including pregnancy-related coronary artery dissection, preeclampsia, and peripartum cardiomyopathy. Finally, the sociocultural dimension of gender should be included in research efforts. The organization of gender medicine must be established as a cross-sectional discipline but also as a centered structure with its own research resources, methods, and questions.

6.Humidifier Disinfectant-Associated Lung Injury: Six Years after the Tragic Event.
Tuberculosis and Respiratory Diseases 2017;80(4):351-357
In 2011, a cluster of peripartum patients were admitted to the intensive care unit of a tertiary hospital in Seoul with signs and symptoms of severe respiratory distress of unknown etiology. Subsequent epidemiological and animal studies suggested that humidifier disinfectant (HD) might represent the source of this pathology. Epidemiological studies, animal studies, and dose-response analysis demonstrated a strong association between HD use and lung injuries. The diagnostic criteria for HD-associated lung injury (HDALI) was defined on the basis of the clinical, pathological, and radiological attributes of the patients. The clinical spectrum of HDALI appears to range from asymptomatic to full-blown acute respiratory failure, and some patients have required actual lung transplantation for survival. The overall mortality of the exposed population was not significant, although peripartum patients and children who were admitted to the intensive care unit did show high mortality rates. Persistent clinical findings such as diffuse ill-defined centrilobular nodules and restrictive lung dysfunction were observed in some of the survivors. The findings of this review emphasize the importance of assessment of the level of toxicity of chemical inhalants utilized in a home setting, as well as the need to identify and monitor afflicted individuals after inhalational injury.

OBJECTIVE: Prophylactic trans-catheter arterial balloon occlusion (PTABO) before cesarean section of placenta previa totalis has been introduced to prevent massive hemorrhage. The purpose of this study is to evaluate the clinical usefulness of PTABO in cases of suspected placental adhesion and to examine antepartal risk factors and perinatal outcomes in women with placental adhesion. METHODS: Between January 2012 and December 2015, 77 patients who had undergone ultrasonography for evaluation of placenta previa were enrolled in this study. Seventeen of these patients with suspected placental adhesion by ultrasonography and Pelvic MRI underwent PTABO before cesarean section and another 59 patients underwent cesarean section without PTABO. Antepartal risk factors and peripartum maternal and neonatal outcomes were compared between patients with PTABO and those without PTABO. RESULTS: More advanced maternal age, longer in gestational weeks at delivery, and more common previous cesarean section history were observed in the PTABO group. Placenta adhesion, abnormal Doppler findings, and frequency of transfusion were more common in the PTABO group. However there was no significant difference in estimated blood loss, hospital days, and neonatal outcome. It had occurred 3 cases of hysterectomy and 1 case of uterine artery embolization after cesarean section in the PTABO group. CONCLUSION: Close surveillance of antepartum risk factors for placental adhesion using ultrasonography and pelvic magnetic resonance imaging is important to prevention of massive hemorrhage during cesarean section. PTABO before cesarean section might result in reduced blood loss and requirement for transfusion during the operation.

8.Practical management of peripartum cardiomyopathy.
The Korean Journal of Internal Medicine 2017;32(3):393-403
Peripartum cardiomyopathy (PPCM) is an idiopathic cardiomyopathy that causes systolic heart failure (HF) in previously healthy young women. Despite latest remarkable achievement, unifying pathophysiologic mechanism is not well established. Considering close temporal relationship to pregnancy, the recent prolactin theory is promising. Abnormal short form of 16-kDa prolactin may be produced in the oxidative stress milieu, show anti-angiogenic effect and damage cardiovascular structure in late pregnancy. Future study is needed to determine whether abnormal prolactin system is useful as a biomarker for diagnosis and therapy of PPCM. Diagnosis is made based on the finding of left ventricular systolic dysfunction after excluding other causes of HF. A multidisciplinary team approach is essential for acute HF, antepartum, labor and postpartum care. Recovery from left ventricular dysfunction is critical for prognosis. As PPCM can recur and cause serious clinical events, subsequent pregnancy is not recommended. This review focuses on the practical management of PPCM.

9.Clinical Characteristics and Prognosis of Peripartum Cardiomyopathy in 28 Patients.
Acta Academiae Medicinae Sinicae 2016;38(1):78-82
OBJECTIVETo analyze the clinical features and prognosis of patients with peripartum cardiomyopathy (PPCM).
METHODSThe clinical data of 28 PPCM patients with PPCM diagnosed in Peking Union Medical College Hospital from January 1983 to December 2014 were retrospectively analyzed and followed up for at least 6 months or to death or cardiac transplantation.
RESULTSAll patients were presented with heart failure. Mean baseline left ventricular ejection fraction (LVEF) was (36.2±11.8)%. After a median follow-up of 27 months, 16 of the 21 patients (76%) showed improvement in LVEF and 5 patients (24%) did not have improvement in their LVEF. Only 1 patient died. There were significant differences between improved and non-improved patients in baseline LVEF (P=0.007), baseline left ventricular end-diastolic dismension (LVEDD) (P=0.040), follow-up LVEF (P<0.001), and follow-up LVEDD (P<0.001). Cox regression analysis showed that higher LVEF (RR: 0.89, 95%CI: 0.83-0.96, P=0.002) and smaller LVEDD (RR: 0.90, 95%CI: 0.83-0.99, P=0.026) were predictors of improvement in LVEF.
CONCLUSIONSEarly diagnosis and regular treatment helps to improve the prognosis of PPCM. Patients with higher LVEF and smaller LVEDD appear to be the most likely to recover.

We recently established a novel disease entity presented as progressive respiratory failure associated with the inhalation of humidifier disinfectants. In April 2011, we encountered a series of peripartum patients with complaints of respiratory distress of unknown etiology, which was an uncommon phenomenon. Accordingly, we created a multidisciplinary team comprising intensivists, radiologists, pathologists, epidemiologists, and the Korea Centers for Disease Control and Prevention (KCDC). Further, we defined the disease entity and performed a case-control study, epidemiologic investigation, and animal study to determine the etiology. The study findings indicated that the lung injury outbreak was related to the inhalation of humidifier disinfectants and showed that household chemical inhalation can cause severe respiratory failure. Following the withdrawal of humidifier disinfectants from the Korean market in 2012, no such cases were reported. This tragic event is a warning that appropriate safety regulations and monitoring for potential toxic household chemicals are critical to protect public health.
