Gestational diabetes mellitus (GDM) is a prevalent metabolic disorder affecting 2.4%-22.3% of pregnancies, with notable regional variation. While most women with GDM return to normal glucose tolerance in the postpartum period, they remain at an increased risk of subsequent metabolic complications, such as type 2 diabetes mellitus, hypertension, and cardiovascular disease.Current Concept: The prevalence of GDM has been increasing globally, including in Korea. Women diagnosed with GDM have an elevated risk of adverse outcomes during pregnancy, such as hypertensive disorders, cesarean sections, and fetal macrosomia. Additionally, GDM increases the long-term risks for type 2 diabetes mellitus, cardiovascular disease, and potentially liver disorders. The growing prevalence of GDM highlights the need for comprehensive surveillance and targeted interventions. Understanding the risk factors, such as lifestyle, ethnicity, maternal age, and pre-pregnancy obesity, is crucial to develop effective prevention and management strategies.Discussion and Conclusion: Addressing the rising GDM trends requires public health efforts to monitor prevalence and mitigate risk factors through lifestyle modifications, early detection, and careful follow-up. Women with a history of GDM are at high risk for cardiometabolic diseases, necessitating proactive postpartum management including regular glucose monitoring and cardiovascular assessments. Establishing tailored preventive strategies and ensuring long-term follow-up for affected women may help reduce the burden of GDM and its associated complications, ultimately improving maternal health and quality of life.

Primary cardiac sarcoma is a rare disease in adults. It is also associated with poor prognoses, due to diagnostic delay, therapeutic difficulty, and high metastatic potential. The coincidence of pregnancy and a primary cardiac intimal sarcoma is extremely rare. We report a pregnant woman at 27(+5) weeks gestation who was admitted to the hospital with acute-onset dyspnea. A mass was found on the left atrium by transthoracic echocardiography. Subsequently, the intracardiac mass was removed, and mitral valve replacement and modified DeVega tricuspid annuloplasty were performed. The patient was diagnosed with a undifferentiated sarcoma, and gave birth to a 1,230 g living baby boy by Caesarean section from preterm contraction at 29(+5) weeks gestation. The patient then received systemic chemotherapy. However, 10 months after the initial clinical onset, the patient suddenly died. Surgery is the standard treatment for cardiac tumors, and their removal should always be attempted, even in pregnant women. Although the overall survival rates of the patients are rather poor, palliative cardiac surgery allows the prolonging of pregnancy, until an acceptable fetal viability level is reached.

Vitamin D deficiency is a global health problem that increases risk for metabolic bone diseases in children and adults as well as many chronic illnesses including autoimmune diseases, type 2 diabetes, cardiovascular disease, infectious disease, and cancer. This has raised important questions concerning the physiological and clinical impact of low vitamin D levels during pregnancy, with implications for functions of vitamin D. The review describes the pathways that are required for metabolism and function of vitamin D, the various clinical complications that have been linked to impaired vitamin D status during pregnancy, and effects of vitamin D supplementation on maternal and neonatal outcomes.

In Korea, various medical big data are available for use in clinical research. More data are expected to be released and used with the increasing social interest in big data. To initiate research using medical big data, it is important to understand the characteristics of data that are suitable for down-stream research. In this review article, we suggest possible research based on published research studies.

Artificial intelligence, which has been applied as an innovative technology in multiple fields of healthcare, analyzes large amounts of data to assist in disease prediction, prevention, and diagnosis, as well as in patient monitoring. In obstetrics, artificial intelligence has been actively applied and integrated into our daily medical practice. This review provides an overview of artificial intelligence systems currently used for obstetric diagnostic purposes, such as fetal cardiotocography, ultrasonography, and magnetic resonance imaging, and demonstrates how these methods have been developed and clinically applied.

Background: Non-obstetric surgery during pregnancy is associated with adverse obstetric and fetal outcomes. The aim of this study was to investigate the risk of adverse pregnancy outcomes for women who underwent non-obstetric pelvic surgery during pregnancy compared with that of women that did not undergo surgery. Methods: Study data from women who gave birth in Korea were collected from the Korea National Health Insurance claims database between 2006 and 2016. We identified pregnant women who underwent abdominal non-obstetric pelvic surgery by laparoscopy or laparotomy from the database. Pregnancy outcomes including preterm birth, low birth weight (LBW), cesarean section (C/S), gestational hypertension, gestational diabetes, and postpartum hemorrhage were identified. The adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the pregnancy outcomes were estimated by multivariate regression models. Results: Data from 4,439,778 women were collected for this study. From 2006–2016, 9,417 women from the initial cohort underwent non-obstetric pelvic surgery (adnexal mass resection, appendectomy) during pregnancy. Multivariate logistic regression analysis indicated that preterm birth (HR, 2.01; 95% CI, 1.81–2.23), LBW (HR, 1.62; 95% CI, 1.46– 1.79), C/S (HR, 1.13; 95% CI, 1.08–1.18), and gestational hypertension (HR, 1.35; 95% CI, 1.18–1.55) were significantly more frequent in women who underwent non-obstetric surgery during pregnancy compared to pregnant women who did not undergo surgery. When the laparoscopic and laparotomy groups were compared for risk of fetal outcomes, the risk of LBW was significantly decreased in laparoscopic adnexal resection during pregnancy compared to laparotomy (odds ratio, 0.62; 95% CI, 0.40–0.95). Conclusion Non-obstetric pelvic surgery during pregnancy was associated with a higher risk of preterm birth, LBW, gestational hypertension, placenta previa, placental abruption, and C/S. Although the benefits and safety of laparoscopy during pregnancy appear similar to those of laparotomy in regard to pregnancy outcomes, laparoscopic adnexal mass resection was associated with a lower risk of LBW.

Samonella infection is usually a short febrile self-limiting disease localized to the gut, acquired by ingestion of contaminated food or water. The infection is seldom accompanied by extraintestinal complication. If such a complication does occur, the abscess is often located in bone and periost. Isolated suppurative ovarian infections are rare, but have descirbed, particularly in dermoid cysts, cystadenomas or endometrioma. We report a case of a patient with a Salmonella typhi infection in a serous cystadenoma.
