Gestational diabetes mellitus (GDM) affects over 10% of all pregnancies, both in Korea and worldwide. GDM not only increases the risk of adverse pregnancy outcomes such as preeclampsia, preterm birth, macrosomia, neonatal hypoglycemia, and shoulder dystocia, but it also significantly increases the risk of developing postpartum type 2 diabetes mellitus and cardiovascular disease in the mother. Additionally, GDM is linked to a higher risk of childhood obesity and diabetes in offspring, as well as neurodevelopmental disorders, including autistic spectrum disorder. This review offers a comprehensive summary of clinical epidemiological studies concerning maternal and fetal complications and explores mechanistic investigations that reveal the underlying pathophysiology.

OBJECTIVES: This study compared the demographic and clinical characteristics of police referrals with referrals from other sources to a psychiatric emergency department. METHODS: A retrospective cross-sectional study was conducted on the data from the psychiatric emergency department of Ulsan University Hospital from January 2014 to October 2017. The study sample consisted of 79 psychiatric patients who were referred by police, and the characteristics of this group were compared with those of 240 psychiatric patients who were referred by other sources. The collected data were analyzed using a chi-square, Fisher's exact test, and independent sample t-tests. RESULTS: Among the 1768 psychiatric emergency visits, 89 (5.0%) were referred by police, and among the 79 referrals by police chosen as the study group, there were 4(5.1%) cases of emergent psychiatric admission. These patients referred by police were more likely to be male and in a lower socio-economic status. Police referrals were more likely to exhibit violent behavior, be restrained, and more likely to visit after working hours. They were notified more rapidly to the psychiatric department, less notified to other departments, and visited the psychiatric outpatient clinics less after discharge from the emergency department. CONCLUSION: The study results highlight the importance of understanding the characteristics of psychiatric emergency patients referred by police and identifying the problems of the current psychiatric emergency services. Systems need to be developed that clarify the roles of police in psychiatric emergencies and facilitate collaboration between police and mental health institutions.

BACKGROUND/AIMS: The nonspecific clinical presentation of acute hepatitis A (AHA) mandates the detection of anti-hepatitis A virus IgM antibodies (IgM anti-HAV) in the serum for obtaining a definitive diagnosis. However, IgM anti-HAV might not be present during the early phase of the disease. The aim of this study was to determine the optimal time for repeating the IgM anti-HAV test (HAV test) in AHA patients with a negative initial test. METHODS: In total, 261 patients hospitalized with AHA were enrolled for this retrospective study. AHA was diagnosed when the test for IgM anti-HAV was positive and the serum alanine aminotransferase (ALT) level was > or =400 IU/L. Repeat HAV test was conducted after 1-2 weeks if the initial HAV test was negative but AHA was still clinically suspected. RESULTS: The results of the initial HAV test were negative in 28 (10.7%) patients. The intervals from symptom onset to the initial-HAV-test day and from the peak-ALT day to the initial-HAV-test day were significantly shorter in the negative-initial-HAV-test group, but on multivariate analysis only the latter was significantly associated with negative results for the initial HAV test (beta=-0.978; odds ratio [95% confidence interval]=0.376 [0.189-0.747]; P=0.005). The HAV test was positive in all patients when it was performed at least 2 days after the peak-ALT day. CONCLUSIONS: The results of HAV tests were significantly associated with the interval from the peak-ALT day to the HAV-test day. The optimal time for repeating the HAV test in clinically suspicious AHA patients with a negative initial HAV test appears to be at least 2 days after the peak-ALT day.

BACKGROUND AND OBJECTIVES: There is a seasonal variation in the incidence of diabetes mellitus and cardiovascular disease. Insulin resistance is important in the development of both non-insulin dependent diabetes mellitus (Type II DM) and cardiovascular disease. Hyperinsulinemia, induced by an insulin resistant state, causes the development of a chronic inflammatory response in vascular structures, which is one of the main causes of cardiovascular disease. There have been several studies on seasonal variation in insulin resistance. Therefore, seasonal variation in insulin resistance were investigated to discover if any relationship existed. SUBJECTS AND METHODS: Korean people examined at a health care center were included. The subjects were divided into four groups, according to the season, and a homeostasis model assessment index (HOMA) calculated, as an indicator of insulin resistance, and compared between the groups. RESULTS: Using the homeostasis model assessment, the highest insulin resistance was observed during winter. Also, the body mass index and waist-hip ratio were highest during winter. CONCLUSION: Compensating for other metabolic factors (age, gender, body mass index, waist-hip ratio and season), insulin resistance was still found to be higher during winter. Seasonal variation in insulin resistance can be associated with the incidence of DM or cardiovascular disease. Therefore, a prospective study will be needed.

BACKGROUND: Insulin resistance is a characteristic feature of uremia and recent studies suggested that it might be one of the causes of muscle wasting. Serum insulin-like growth factor 1 (IGF-1) has been known as one of marker of malnutrition in end-stage renal disease (ESRD) patients. However, there were few studies on the relationship between IGF-1 and insulin resistance. METHODS: We measured serum IGF-1, prealbumin, albumin, plasma insulin and glucose concentration and body composition by dual energy X-ray absorptiometry in 20 non-diabetic ESRD patients who admitted to start dialysis. Homeostasis model assessment method of insulin resistance (HOMA-IR) was used for insulin resistance. RESULTS: Patients with IGF-1 <200 ng/mL (n=6) had significantly lower body weight (BW), body mass index (BMI), prealbumin (29.8+/-7.0 vs. 39.7+/-9.3 mg/ dL, p=0.022), Fat mass, pFat (percent fat mass), pFat-limb and HOMA-IR (1.44+/-0.59 vs. 3.47+/-2.22, p=0.04) than those with >200 ng/mL (n=14). IGF-1 showed positive correlations with BMI (r=0.45), prealbumin (r=0.6), Fat-limb (r=0.51), and HOMA-IR (r=0.67). On WHO classification for weight status, IGF-1 seemed to be higher when weight status was increased from underweight (151.8+/-41.6 ng/mL) to overweight (371.8+/-109.8 ng/mL) and these trends were similar to those of HOMA-IR. On multivariate analysis, IGF-1 was independent variable for affecting HOMA-IR. CONCLUSION: Serum IGF-1 concentration seems to be associated with insulin resistance in ESRD patients and reflect body composition, especially fat mass.

In August 2008, forty dogs out of 400 developed oral warts in a breeding farm in Korea. Canine oral papilloma infection is a common disease in dogs. However, there has been no report of an outbreak of canine oral papillomavirus (COPV) in a group of dogs or in dog breeding farms in Korea, and the genetic analysis of COPV in Korea has yet to be performed. This study diagnosed canine oral papilloma from the oral samples of these dogs based on histopathological examination and immunohistochemistry. Polymerase chain reaction was applied to amplify the corresponding products using pre-existing primer sets for COPV and a universal human papillomavirus targeting L1 gene. Further genetic analysis of the major viral capsid gene L1 confirms the sequences of Korean COPV, which shows a close relationship to previously reported COPV. This study describes the histopathological and immunohistochemical characteristics of canine oral papilloma in a group of breeding dogs in Korea and discloses the complete L1 gene sequences of Korean COPV.

BACKGROUND/AIMS: We aimed to clarify the association of hepatitis B surface antigen (HBsAg)/hepatitis B core antigen (HBcAg) with the disease status and treatment response in patients with chronic hepatitis B (CHB). METHODS: We investigated 171 biopsy-proven entecavir-treated CHB patients (109 hepatitis B e antigen [HBeAg]-positive, 62 HBeAg-negative). HBcAg expression was positive when ≥10% of hepatocytes stained, and classified into nuclear, mixed, and cytoplasmic patterns. HBsAg expressions were intracytoplasmic (diffuse, globular, and submembranous) and membranous. The histologic activity index (HAI) and fibrosis stage followed Ishak system. RESULTS: In HBeAg-positive patients, older age, increased HAI score, advanced fibrosis, and reduced viral load were observed when HBcAg expression shifted from nucleus to cytoplasm in HBcAg-positive patients, and HBsAg expression from non-submembranous to submembranous in HBcAg-negative patients (all, p<0.05). In HBeAg-negative patients, only intracytoplasmic HBsAg expression patterns had clinical relevance with decreased ALT levels and viremia. In HBeAg-positive patients without favorable predictors of virologic response, negative HBcAg and membranous HBsAg expression predicted greater virologic response (both, p<0.05). The probability of HBeAg seroclearance was higher in patients with increased HAI or lacking HBcAg expression (both, p<0.05). Higher serum HBsAg levels and hepatocyte HBcAg positivity were associated with reduced serum HBsAg during first and post-first year treatment, respectively (both, p<0.05). CONCLUSIONS: Hepatocyte HBcAg/HBsAg expression is a good marker for disease status and predicting treatment response.
