Artificial intelligence (AI)-based diagnostic technology using medical images can be used to increase examination accessibility and support clinical decision-making for screening and diagnosis. To determine a machine learning algorithm for diabetes complications, a literature review of studies using medical image-based AI technology was conducted using the National Library of Medicine PubMed, and the Excerpta Medica databases. Lists of studies using diabetes diagnostic images and AI as keywords were combined. In total, 227 appropriate studies were selected. Diabetic retinopathy studies using the AI model were the most frequent (85.0%, 193/227 cases), followed by diabetic foot (7.9%, 18/227 cases) and diabetic neuropathy (2.7%, 6/227 cases). The studies used open datasets (42.3%, 96/227 cases) or directly constructed data from fundoscopy or optical coherence tomography (57.7%, 131/227 cases). Major limitations in AI-based detection of diabetes complications using medical images were the lack of datasets (36.1%, 82/227 cases) and severity misclassification (26.4%, 60/227 cases). Although it remains difficult to use and fully trust AI-based imaging analysis technology clinically, it reduces clinicians’ time and labor, and the expectations from its decision-support roles are high. Various data collection and synthesis data technology developments according to the disease severity are required to solve data imbalance.

PURPOSE: The purpose of this study was to evaluate the relationship between maternal genital Ureaplasma urealyticum colonization in the second trimester and the neonatal outcomes. METHODS: We studied 577 premature infants born at ≤35 weeks' gestational age (GA) at Hallym University, Kangnam Sacred Heart Hospital from January 2008 to December 2014. Maternal vaginal specimens were collected and polymerase chain reaction and/or culture tests were done in the second trimester of pregnancy. The subjects were divided into 2 groups: a Uu colonization-positive group (UU) and a Uu-negative (control) group. Subgroup analyses were performed in extremely premature (23–28 weeks' GA) and premature (29–35 weeks' GA) infants. Various clinical outcomes were compared. RESULTS: Of 577 preterm infants, 311 were delivered with maternal Uu infection (UU, 53.9%). Mean GA (30.0±3.6 weeks vs. 31.0±3.7 weeks, P=0.010) and birth weight (1,685.6±680.4 g vs. 1,932.7±733.1 g, P=0.003) were lower in the UU group than in controls. However, there were no significant differences in GA and birth weight in extremely premature group. Premature labor (P=0.002) and histological chorioamnionitis (P=0.032) was significantly more common in the UU group, especially in mothers who delivered in third trimester (29–35 weeks' GA). In particular, the incidence of moderate-to-severe BPD was statistically higher in UU extremely premature group (60.8% vs. 32.2%) (P=0.001). CONCLUSION: Maternal colonization with Uu was associated with an increase in premature delivery and lower birth weights. Moderate-to-severe BPD was more common in premature infants born at ≤28 weeks' GA with maternal Uu colonization.

Purchasing professionals utilize a e-commerce to sell or buy better products with good price. The marketers of agricultural products recognized that e-commerce has made significant inroads, and the Internet is fast becoming an essential tool for purchasing. The purpose of this research was to assess the realities of internet shopping malls of agricultural products including the actual condition of the sites, payment methods, order methods, membership and shipping methods. The results show that operating internet shopping mall of agricultural products are operated poorly in terms of buyer-seller relationship, payment and distribution. The results also provide some practical implication for marketers regarding the establishment of database, improvement of distribution and internet shopping mall operation, and importance of education on e-business for agricultural markets.

OBJECTIVES: The aim of this study is to confirm the clinical and histopathologic findings of ovarian tumors and determine the malignancy before operation. It will attribute to early diagnosis, determining direction of treatment and improving prognosis of malignant ovarian tumor. METHODS: Seven hundred sixty-five patients who had an operation for ovarian tumors in the department of Obstetrics and Gynecology of Gachon University Gil Medical Center from April 2007 to December 2009 were enrolled as subjects. A retrospective analysis of age, parity, menopausal status, preoperative CA 125, histology, ultrasound, and treatment method was done. RESULTS: 1. Among benign ovarian tumors, endometrial cyst (211 cases, 30.1%) was most common and had the highest preoperative CA 125 (76.07 U/mL). 2. Among borderline ovarian tumors, mucinous type (16 cases, 62.5%) was most common, but preoperative CA 125 was higher in serous type (144.38 U/mL) than mucinous type (82.59 U/mL). 3. Among malignant ovarian tumors, serous adenocarcinoma (14 cases, 29.8%) was most common, and undifferentiated carcinoma had the highest preoperative CA 125 (500.0 U/mL). 4. The preoperative CA 125 showed a tendency to increase in relation to stage in malignant ovarian tumors. 5. Age, preoperative CA 125, menopausal status and ultrasound finding were identified as discriminating factors for malignancy and relative risk of them were 7.19, 7.90, 5.56 and 61.43, respectively. CONCLUSION: Using the combination of age, menopausal status, preoperative CA 125 and ultrasound to diagnose ovarian tumors before the operation will be a help to early diagnosis and determining the treatment and improve prognosis.

OBJECTIVE: The aim of this study was to investigate whether embryonic stem (ES) cells can be established from isolated blastomeres of mouse embryos. METHODS: Blastomeres were separated from mouse (C57Bl/6J) 2- or 4-cell embryos. Isolated blastomeres or whole 4-cell embryos were co-cultured with mitosis-arrested STO feeder cells in DMEM supplemented with recombinant murine leukemia inhibitory factor and ES-qualified fetal bovine serum. After the tentative ES cell lines were maintained from isolated blastomeres or whole embryos, some of them were frozen and the others were sub-cultured continually. Characteristics of tentative ES cell lines as were evaluated for specific gene expressions with immunocytochemistry and RT-PCR. RESULTS: One ES cell line (3.0%) was established from isolated blastomere of 2-cell embryo and one cell line (4.0%) from isolated two blastomeres of 4-cell embryo. And five cell lines (16.7%) were established from whole 4-cell embryos. Both cell lines from isolated blastomere and whole embryo expressed mouse ES cells specific markers such as SSEA-1, Oct-4 and alkaline phosphatase. Marker genes of three germ layers were expressed from embryoid bodies of both cell lines. CONCLUSION: This study suggests that mouse ES cells could be established from isolated blastomeres, although the efficiency is lower than whole embryos. This animal model could be applied to establishment of autologous human ES cells from biopsied blastomeres of preimplantation embryos in human IVF-ET program.

OBJECTIVE: Teeth discoloration is a rare orthodontic complication. The aim of this study was to report the clinical progression of discoloration during orthodontic treatment. METHODS: Discolored teeth, detected during orthodontic treatment between January 2003 and December 2012 by a single dentist using similar techniques and appliances, were analyzed. RESULTS: The total number of teeth that showed discoloration was 28. Progression of discoloration was evaluated in only 24 teeth that were observed without any treatment. During the observation period, the discoloration “improved” in 8 of the 24 teeth (33.3%) and was “maintained” in 16 (66.6%). The electric pulp test performed at the time of initial detection of discoloration showed 14.3% positivity, which improved to 21.4% at the final follow-up. None of the initial and final follow-up radiographic findings showed any abnormalities. CONCLUSIONS: When teeth discoloration is detected during orthodontic treatment, observation as an initial management is recommended over immediate treatments.

PURPOSE: To compare information about fracture type in MRI with simple radiograph in tibial plateau fractures and evaluate tibial plateau fractures type and accompanying soft tissue injury, and evaluate usefulness of MRI in tibial plateau fractures. MATERIALS AND METHODS: Compared MRI with simple radiograph about Schatzker classification, depression of articular surface and displacement of bone fragment from the 68 examples who checked MRI and we evaluated soft tissue injury around knee joint. RESULTS: There were 7 examples of Schatzker type change after MRI check. Average depression of articular surface in simple radiograph was 2.93 mm and 4.28 mm in MRI. It increased by 1.35 mm and it was meaningful statistically (p<0.05). There was no significant difference between MRI and simple radiograph of displaced bone fragment (p=0.168). There were 58 (85.3%) cases of soft tissue injury in MRI. CONCLUSION: MRI can find additional fracture line or articular depression that can't be found in simple radiograph and gives more information about articular depression and soft tissue that is useful in surgical plans. I think preoperative MRI is necessary to better treatment of fracture & treatment of periarticular soft tissue injury in tibial plateau fracture.
