Pregnancy Outcomes of Women Additionally Diagnosed as Gestational Diabetes by the International Association of the Diabetes and Pregnancy Study Groups Criteria.

Background: We investigated the pregnancy outcomes in women who were diagnosed with gestational diabetes mellitus (GDM) by the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) criteria but not by the Carpenter-Coustan (CC) criteria.

Methods: A total of 8,735 Korean pregnant women were identified at two hospitals between 2014 and 2016. Among them, 2,038 women participated in the prospective cohort to investigate pregnancy outcomes.

Progression to Gestational Diabetes Mellitus in Pregnant Women with One Abnormal Value in Repeated Oral Glucose Tolerance Tests.

Background: Women with one abnormal value (OAV) in a 100 g oral glucose tolerance test (OGTT) during pregnancy are reported to have an increased risk of adverse pregnancy outcomes. However, there is limited data about whether women with OAV will progress to gestational diabetes mellitus (GDM) when the OGTT is repeated.

Methods: To identify clinical and metabolic predictors for GDM in women with OAV, we conducted a retrospective study and identified women with OAV in the OGTT done at 24 to 30 weeks gestational age (GA) and repeated the second OGTT between 32 and 34 weeks of GA.

Addition of Cervical Elastography May Increase Preterm Delivery Prediction Performance in Pregnant Women with Short Cervix: a Prospective Study.

Background: We investigated whether there is a difference in elastographic parameters between pregnancies with and without spontaneous preterm delivery (sPTD) in women with a short cervix (≤ 25 mm), and examined the ability of elastographic parameters to predict sPTD in those women.

Methods: E-Cervix (WS80A; Samsung Medison, Seoul, Korea) elastography was used to examine the cervical strain. Elastographic parameters were compared between pregnancies with and without sPTD.

Delphinidin inhibits epidermal growth factor-induced epithelial-to-mesenchymal transition in hepatocellular carcinoma cells.

Epithelial-to-mesenchymal transition (EMT), important cellular process in metastasis of primary tumors, is characterized by loss of their cell polarity, disruption of cell-cell adhesion, and gain certain properties of mesenchymal phenotype that enable migration and invasion. Delphinidin is a member of anthocyanidin belong to flavonoid groups, known as having pharmacological and physiological effects including anti-tumorigenic, antioxidative, anti-inflammatory, and antiangiogenic effects. However, the effects of delphinidin on EMT is rarely investigated.

Risk factors for cytological progression in HPV 16 infected women with ASC-US or LSIL: The Korean HPV cohort.

Objective: This study was to identify the risk factors for cytological progression in women with atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesions (LSIL).

Methods: We analyzed data from women infected with the human papillomavirus (HPV) who participated in the Korean HPV cohort study. The cohort recruited women aged 20-60 years with abnormal cervical cytology (ASC-US or LSIL) from April 2010.

Isotretinoin exposure in pregnant women in Korea.

Objective: Isotretinoin is a notorious teratogen otherwise used for the treatment of acne vulgaris. Some countries, including those in North America and the European Union, implemented the pregnancy prevention program (PPP); however, no PPP has yet been established in South Korea. So the aim of this study was to evaluate the rate of pregnant women exposed to isotretinoin among the callers of the Korean Mother Safe Counseling Center.

Is injury to the inferior alveolar nerve still common during orthognathic surgery? Manual twist technique for sagittal split ramus osteotomy.

The osteotomy in a bilateral sagittal split ramus osteotomy (BSSRO) is made in close proximity to the inferior alveolar nerve (IAN), so direct damage to the nerve and irreversible neurosensory deficit may result. The aim of this study was to compare the incidence of injury to the nerve when a conventional osteotomy using an osteotome was made, with that after manual twist splitting. We retrospectively reviewed the casenotes of 769 consecutive patients who had bilateral SSRO either alone or with a simultaneous maxillary procedure by a single surgeon from May 2009 - October 2016.

Questionnaire study of the dietary habits of breast cancer survivors and their relationship to quality of life (KROG 14-09).

We evaluated the dietary habits of breast cancer survivors and investigated the relationship with quality of life (QoL), with 1,156 survivors recruited from 17 institutions. We used the Questionnaire Survey of Dietary Habits of Korean Adults (Q-DH-KOR) comprising 25 questions. The following indices were derived as follows: (1) quality of healthy dietary habits (Q-HD)-eight questions on number of meals, regularity, quantity, duration, skipping breakfast, dinner with companion(s), overeating and late-night snacks; (2) habits of nutritional balance (H-NB)-questions on consuming five food categories (grains, fruits, proteins, vegetables and dairy products); and (3) habits of unhealthy foods (H-UF)-questions on consuming three food categories (fatty, instant and fast foods).

Real-world effectiveness of bevacizumab based on AURELIA in platinum-resistant recurrent ovarian cancer (REBECA): A Korean Gynecologic Oncology Group study (KGOG 3041).

Purpose: To evaluate the effectiveness of bevacizumab with single-agent chemotherapy for platinum-resistant ovarian cancer in a real-world setting.

Patients And Methods: We enrolled recurrent platinum-resistant ovarian cancer patients from 27 institutions. All had received bevacizumab with single-agent chemotherapy (weekly paclitaxel, pegylated liposomal doxorubicin (PLD), topotecan) between 2015 and 2017 for second- or third-line chemotherapy in routine clinical practice.

Effective Fetal Epigenetic Biomarkers for Noninvasive Fetal Trisomy 21 Detections.

Introduction: Recently, we identified three novel fetal-specific epigenetic DNA regions (FSERs) on chromosome 21 for detection of noninvasive fetal trisomy 21 (T21). In this study, the diagnostic accuracies of the three FSERs were assessed on a larger panel of the first-trimester pregnant women.

Material And Methods: This study was conducted with maternal plasma collected from 167 pregnant women carrying 155 chromosomally normal and 12 T21 fetuses (10-13 gestational weeks).

Importance of family history of diabetes in computing a diabetes risk score in Korean prediabetic population.

Prediabetic subjects represent a vulnerable population, requiring special care to reduce the risk of diabetes onset. We developed and validated a diabetes risk score for prediabetic subjects using the Korea National Diabetes Program (KNDP) cohort. Subjects included in the multicenter and prospective cohort (n = 1162) had high diabetes risk at baseline (2005) and were followed until 2012.

High Genetic Risk Scores of ASIC2, MACROD2, CHRM3, and C2orf83 Genetic Variants Associated with Polycystic Ovary Syndrome Impair Insulin Sensitivity and Interact with Energy Intake in Korean Women.

Background: We explored the genetic variants that were associated with polycystic ovary syndrome (PCOS) by genome-wide association study (GWAS) and evaluated the association of genetic risk scores (GRS) of the selected genetic variants with insulin resistance and the interaction of the GRS with nutrient intake to develop insulin resistance.

Methods: The 6 genetic variants involved in brain and nervous system (acid sensing ion channel subunit 2 rs8071961, rs1988598, and rs16589, macro domain containing 2 rs7262810 CHRM3 rs1867265 and chromosome 2 open reading frame 83 rs11889798) were selected from a GWAS of the PCOS study. GRS of the 6 single nucleotide polymorphisms was calculated in 3,723 Korean women in the Ansan/Ansung cohort of KARE study.

Materials And Methods: Between March 2003 and October 2015, total 64 cases of cesarean scar pregnancy (CSP) were retrospectively reviewed. The cliniscal characteristics, diagnosis, various methods of treatment and clinical outcomes were analyzed.

Risk factors of persistent HPV infection after treatment for high-grade squamous intraepithelial lesion.

Purpose: To evaluate the risk factors associated with persistent high-risk human papillomavirus (HR HPV) infections in patients undergoing cervical excision for treatment of high-grade squamous intraepithelial lesion (HSIL).

Methods: A retrospective cohort study included 160 patients who underwent cervical excision for treatment of HSIL between January 2014 and December 2014. The clinical characteristics, cervical cytology, and HPV test results were reviewed.

Sex Differences in Lower Urinary Tract Symptoms in Older Korean Adults Living in Rural Areas: Prevalence, Quality of Life, and Associated Factors.

Purpose: Urinary incontinence (UI) is associated with nursing home admission, functional decline, and risk of death among community-dwelling older adults. Little information, however, is available on sex differences in lower urinary tract symptoms (LUTS) in older Korean adults exclusively living in rural areas. This study examined sex-related differences in LUTS, factors associated with UI in older adults living in rural areas, and health-related quality of life (HRQoL) in incontinent older adults.

Comparative Study between Sentinel Lymph Node Biopsy and Axillary Dissection in Patients with One or Two Lymph Node Metastases.

Purpose: Sentinel lymph node biopsy (SLNB) is a standard axillary surgery in early breast cancer. If the SLNB result is positive, subsequent axillary lymph node dissection (ALND) is a routine procedure. In 2011, the American College of Surgeons Oncology Group Z0011 trial revealed that ALND may not be necessary in early breast cancer with one or two positive sentinel lymph nodes.

Assessment of patient-reported outcomes (PROs): treatment satisfaction, medication adherence, and quality of life (QoL) and the associated factors in postmenopausal osteoporosis (PMO) patients in Korea.

Patient-reported outcomes (PROs) provide practical guides for treatment; however, studies that have evaluated PROs of women in Korea with postmenopausal osteoporosis (PMO) are lacking. This cross-sectional, multi-center (29 nationwide hospitals) study, performed from March 2013 to July 2014, aimed to assess PROs related to treatment satisfaction, medication adherence, and quality of life (QoL) in Korean PMO women using osteoporosis medication for prevention/treatment. Patient demographics, clinical characteristics, treatment patterns, PROs, and experience using medication were collected.

Early gonadotropin-releasing hormone antagonist protocol in women with polycystic ovary syndrome: A preliminary randomized trial.

Objective: To prospectively evaluate the efficacy and safety of a fixed early gonadotropin-releasing hormone (GnRH) antagonist protocol compared to a conventional midfollicular GnRH antagonist protocol and a long GnRH agonist protocol for fertilization (IVF) in patients with polycystic ovary syndrome (PCOS).

Methods: Randomized patients in all three groups (early antagonist, n=14; conventional antagonist, n=11; long agonist, n=11) received 21 days of oral contraceptive pill treatment prior to stimulation. The GnRH antagonist was initiated on the 1st day of stimulation in the early antagonist group and on the 6th day in the conventional antagonist group.

Clinical value of chromosomal microarray analysis in prenatally diagnosed dextro-transposition of the great arteries.

To evaluate the usefulness of chromosomal microarray analysis (CMA) in fetuses with dextro-transposition of the great arteries (d-TGA). Thirty-two fetuses with d-TGA were examined for submicroscopic copy number variations (CNVs) using CMA. Among the 32 d-TGA fetuses, 23 had isolated lesions (71.

Efficacy and safety of ferric carboxymaltose versus ferrous sulfate for iron deficiency anemia during pregnancy: subgroup analysis of Korean women.

Background: We performed a post-hoc subgroup analysis in Korean women who participated in the Phase III FER-ASAP (FERric carboxymaltose-Assessment of SAfety and efficacy in Pregnancy) study to compare the efficacy and safety of ferric carboxymaltose (FCM) with oral ferrous sulfate (FS).

Methods: Pregnant Korean women (gestational weeks 16-33) with iron-deficiency anemia (IDA) were randomized 1:1 to FCM (n = 46; 1000-1500 mg iron) or FS (n = 44; 200 mg iron/day) group for 12 weeks. The primary objective was to compare the mean hemoglobin (Hb) increase at week 3; secondary objectives included change in iron parameters, quality of life (QoL), and safety.

Use of child safety seats during transportation of newborns.

Purpose: Child safety seats (CSS) are critical for the protection of children, in case of motor vehicle accidents. Although the national legislation mandates that all newborns must be placed in an appropriately installed CSS during transportation, people often do not perceive the importance of CSS and do not use it as recommended. The purpose of this survey was to understand the use of CSS for the safe transport of newborns from hospital to home.
