World Journal of Pediatrics 2021年第5期17卷 555-556页

作者： ji yoon Oh Soo-young Lee Department of Pediatrics Bucheon St.Mary's HospitalCollege of MedicineThe Catholic University of Korea327 Sosa-roWonmi-guBucheon 14647.Republic of Korea

Management of febrile infants,especially those younger than 3 months of age,is of clinical importance due to the relatively high risk of serious bacterial infection(SBI),such as bacterial meningitis,bacteremia,or urinary tract infection(UTI)[1].Fortunately,reliable guidelines for assessing the risk of SB I in febrile infants have been developed to help determine whether an infant should be hospitalized,undergo lumbar puncture,or be treated with antibiotics[2].However,many hospitals do not have written institutional guidelines,so clinicians often make decisions based on their own experience and knowledge[3-5].For a consistent approach to febrile infants,our hospital plans to introduce written *** this study,we estimated the expected effects of these guidelines and compared our data with the results of previous domestic studies.

AIM To investigate the clinicopathological features and prognostic implications of combined MYC and fibroblast growth factor receptor 1(FGFR1) status in esophageal squamous cell carcinomas(ESCCs). METHODS All patients with ESCC(n = 180) underwent surgical resection at Seoul National University Hospital sometime between 2000 and 2013. A tissue microarray was constructed using cores obtained from representative tumor areas of formalin-fixed, paraffin-embedded tissue blocks. FGFR1 and MYC copy numbers were quantified using fluorescence in situ hybridization. The level of MYC expression was determined using immunohistochemistry. FGFR1 and MYC amplification status was compared between primary and metastatic lymph nodes. Univariate and multivariate survival analyses were performed according to adjuvant therapy *** FGFR1 and MYC amplifications were observed in 21.4%(37/173) and 54.2%(91/168) of patients, respectively, while MYC expression was observed in 58.9%(106/180) of patients. There was a positive correlation between MYC amplification and overexpression(P = 0.002). Although FGFR1 amplification was not associated with MYC amplification or expression, 12.3%(20/163) of patients exhibited both FGFR1 amplification and MYC expression. There was also a correlation in FGFR1 amplification status between matched primary tumors and metastatic lymph nodes(P < 0.001). MYC expression was higher in ESCCs with p T1(P < 0.001) and in those with no lymph node metastasis(P = 0.023). MYC expression was associated with prolonged diseasefree survival(P = 0.036) and overall survival(OS)(P = 0.017) but was not an independent prognostic factor. FGFR1 amplification was an independent predictor for prolonged OS in all patients(P = 0.029) and in those who did not receive adjuvant therapy(P = 0.013). Combined FGFR1 amplification and MYC expression predicted better OS in patients who did not receive adjuvant therapy(P = 0.034) but not in those who did receive adjuvant ***

Epidemic obesity in children and adolescents:risk factors and prevention

引用

Frontiers of Medicine 2018年第6期12卷 658-666页

作者： Eun young Lee Kun-Ho yoon Division of Endocrinology and Metabolism Department of Internal MedicineSeoul St.Mary's HospitalCollege of MedicineThe Catholic University of KoreaSeoul 06591Korea Institute of Catholic Ubiquitous Health Care The Catholic University of KoreaSeoul 06591Korea

The prevalence of obesity among children and adolescents (aged 2-18 years) has increased rapidly, with more than 100 million affected in 2015. Moreover, the epidemic of obesity in this population has been an important public health problem in developed and developing countries for the following reasons. Childhood and adolescent obesity tracks adulthood obesity and has been implicated in many chronic diseases, including type 2 diabetes, hypertension, and cardiovascular disease. Furthermore, childhood and adolescent obesity is linked to adulthood mortality and premature death. Although an imbalance between caloric intake and physical activity is a principal cause of childhood and adolescent obesity, environmental factors are exclusively important for development of obesity among children and adolescents. In addition to genetic and biological factors, socioenvironmental factors, including family, school, community, and national policies, can play a crucial role. The complexity of risk factors for developing obesity among children and adolescents leads to difficulty in treatment for this population. Many interventional trials for childhood and adolescent obesity have been proven ineffective. Therefore, early identification and prevention is the key to control the global epidemic of obesity. Given that the proportion of overweight children and adolescents is far greater than that of obesity, an effective prevention strategy is to focus on overweight youth, who are at high risk for developing obesity. Multifaceted, comprehensive strategies involving behavioral, psychological, and environmental risk factors must also be developed to prevent obesity among children and adolescents.

Feasibility Study of R134a/R404a Cascade Heat Pump Cycle in Heat Pump Dryers with Electrical Heaters at Low Temperatures

引用

Journal of Thermal Science 2015年第5期24卷 463-467页

作者： ji Woo Jeong young Lim Lee Dept. of Mechanical Engineering Kongju National University Dept. of Mechanical and Automotive Engineering Kongju National University

Heat pump cycles have been widely applied to dryers for their high efficiency. However, low–efficiency electrical heaters are often used during early drying stage for frozen foods or winter since a standard heat pump cycle cannot operate at low temperature. This study introduced cascade heat pumps replacing electrical heaters to improve dryer performance at low temperatures. Experiments were performed to examine changes in performance of the cascade heat pump dryers in relation to ambient temperature, low-stage cycle mass flow rate, and high-stage cycle mass flow rate. The results showed a significant improvement in low-temperature dryer performance with the introduction of cascade heat pump cycles.

引用

International Journal of Ophthalmology(English edition) 2019年第3期12卷 393-400页

作者： Won Choi Jun young Ha Ying Li Jung Han Choi Yong Sok ji Kyung Chul yoon Department of Ophthalmology and Research Institute of Medical Sciences Chonnam National University Medical School and Hospital

AIM: To investigate the abnormalities in the meibomian gland in patients with dry eye disease(DED) associated with chronic ocular graft-versus-host disease(coGVHD) in comparison with Sj?gren's syndrome(SS), a major form of aqueous deficient DED and meibomian gland dysfunction(MGD), a common cause of evaporative ***: A total 135 eyes of 135 subjects included in this study: patients with DED associated with coGVHD(n=30), patients with SS(n=35), patients with MGD(n=35), and normal controls(n=35). All participants completed the Ocular Surface Disease Index(OSDI) questionnaire, ocular surface examination [Schirmer test, tear film breakup time(TFBUT), and ocular surface staining], and meibomian gland assessment [meiboscore(gland dropout detected on meibography using infrared camera of the Keratograph 5 M), meibum expressibility score(MES), meibum quality score(MQS), lid margin abnormality]. In addition, correlations of meibomian gland characteristics with ocular surface parameters as well as disease severity score were investigated in coGVHD ***: The coGVHD group showed significantly higher meiboscore, MES, and MQS than the other 3 groups(all P<0.05). In the coGVHD group, parameters of meibomian gland showed a significant correlation each other and those of ocular surface. The correlation between meibomian gland parameters and severity score of co GVHD was also established(meiboscore, r=0.62; MES, r=0.47; MQS, r=0.47; lid margin abnormality score, r=0.55; all P<0.05).CONCLUSION: Patients with DED associated with co GVHD show poorer gland morphology and worse glandfunction than other types of DED. In addition, meibomian gland damage is not only associated with ocular surface damage but also disease severity of coGVHD.
