OBJECTIVES: Intake of fruits and vegetables has protective effects against stroke attack. This study intended to examine the status of consuming fruits and vegetables and to find out which factors may influence the frequency of consumption of fruits and vegetables in individuals with a history of stroke. METHODS: The data of 208 subjects from 5th (2010, 2011) Korea National Health and Nutrition Examination Survey (KNHNES) who reported a stroke diagnosis was used for analysis. To identify major factors influencing the consumption of fruits and vegetables, a classification-tree analysis was carried out. RESULTS: Among those who reported a stroke diagnosis, the frequencies of consumption of fruits and vegetables were influenced by their age, place of residence (urban or rural), economic status, educational level, occupation, number of family members, frequency of eating out, and having meals (breakfast or lunch) with family members. Two factors from fruits and three factors from vegetables were generated by exploratory factor analyses. Urban residents ate fruits and vegetables more frequently in all factors than rural residents. Eating frequencies of 'seasonal fruits (orange, apple, strawberry, melon, pear and watermelon)', 'easily-accessible fruits (persimmon, tangerine, grape, peach, banana)', and 'Western-style vegetables (cabbage, mushroom, carrot, tomato, spinach)' were influenced by the socioeconomic status. Eating frequencies of 'Korean-style vegetables (bean sprout, radish leaves, pumpkin/squash, sea weed)', 'preserved vegetables (Korean cabbage, radish, laver, cucumber)' were influenced by having breakfast with amily members. CONCLUSIONS: The results of this study suggested that by eating more fruits and vegetables, more preventive effects against secondary stroke attack are expected in stroke patients who live in the rural areas and who do not eat breakfast with family members. In addition, more outreach and education programs are needed for them.

OBJECTIVE: Public concerns and awareness of automated external defibrillators (AEDs) are essential for improving the survival outcomes of out-of-hospital cardiac arrest (OHCA) in the community. On the other hand, the proportion of OHCA, in which AED is used in a prehospital setting, is very low in Korea. The aim of this study was to identify the barriers and training issues of AEDs. METHODS: A nationwide population-based survey was conducted to analyze the current public trends in AED awareness, training, and intention to use in 2017 (n=506). The barriers and training issues of AEDs were then documented. For trend analysis, previous tri-temporal surveys were obtained in 2007, 2011, and 2015. RESULTS: Public awareness of AEDs has increased: from 5.8% in 2007, to 30.6% in 2011, 82.6% in 2015, and 79.4% in 2017 (P<0.001). The training experience of AEDs has increased over time: from 0.5% in 2007 to 8.2% in 2011 and 33.2% in 2017. Thirty-two percent of respondents knew how and where to find the AEDs, but only 12.5% were able to certainly locate their public-access AED near their residency or work places. The reasons for being unwilling to use the AED included not knowing how to use (65.0%), fear of causing harm to the victim (21.3%), and legal liability (11.7%). CONCLUSION: Not knowing the location of AED and how to use it, and being unaware of the Good Samaritan Law were the major barriers to public access defibrillation. Further research is urgently needed if AEDs are to be increased and more lives saved.

This article reports a case of spontaneous ovarian hyperstimulation syndrome (OHSS) following a thawed embryo transfer cycle. OHSS, a potentially life-threatening condition, is an iatrogenic complication of controlled ovarian stimulation; therefore, it is very important to prevent and treat OHSS during treatment with ovulation-inducing agents. Despite our efforts to prevent OHSS, in this case, severe spontaneous OHSS occurred, which resulted in uncontrolled preterm labor and a preterm delivery and also persisted for 6 weeks after delivery. Freezing all embryos cannot entirely prevent the development of OHSS because OHSS can occur spontaneously. Although spontaneous OHSS remains a rare event, females with a history of OHSS may have an elevated risk for spontaneous OHSS. We suggest closely monitoring cases of pregnancy following thawed embryo transfer for early diagnosis of spontaneous OHSS and the use of conservative management.

BACKGROUND/OBJECTIVES: This study explores the parental characteristics that affect the eating behaviors of preschool children. The nutrition quotient for preschool children (NQ-P) tool was applied to measure the eating behaviors of preschool children, and the relationship between parents’ health beliefs and children’s eating behaviors was investigated by applying the health belief model.MATERIALS/METHODS: In August 2018, a self-administered online survey was conducted on a sample of parents of children aged 3 to 5 years living in the Seoul and Gyeonggi area. A total of 248 respondents were analyzed via descriptive statistics, one-way ANOVA, Tukey’s multiple comparison test, Pearson correlation analysis, and multiple regression analysis. RESULTS: The eating behaviors of preschool children significantly differed based on parents’ education level and monthly income (P < 0.01). Among the factors of the health belief model, “perceived benefit” had the highest score at 4.37 points. The multiple regression analysis confirmed that parents’ “self-efficacy” raised the NQ-P scores (β = 0.175, P< 0.05), balance scores (β = 0.204, P < 0.01), and environment scores of preschool children (β = 0.149,P < 0.05). The study results showed that if parents are educated on healthy eating habits and their level of self-efficacy for healthy eating practices increases, the formation of correct eating behaviors for preschool children is more likely. CONCLUSION This study provides preliminary data to develop an education program for parents to understand proper eating behaviors for their children and may help form healthy eating habits and encourage the healthy growth of preschool children.

PURPOSE: Exposure to blood and body fluids represents a significant occupational risk for nurses. This study was done to identify the level of knowledge of and compliance with blood-borne pathogen prevention of hospital nurses according to clinical experience, and to identify factors affecting compliance with blood-borne pathogen prevention. METHODS: A descriptive correlational study was conducted in which self-reported knowledge of and compliance with blood-borne pathogen prevention was assessed. The relationships between variables were examined. Registered nurses who were employed (n=345) were surveyed. Data were analyzed using, t-test, ANOVA, Pearson correlation, and multiple linear regression. RESULTS: Nurses with more than 5 years experience had greater knowledge of blood-borne pathogen prevention than nurses with less than 5 years experience. However, there was no significant difference in compliance with blood-borne pathogen prevention between the two groups. No significant correlation was found between knowledge and compliance with blood-borne pathogen prevention according to experience standards. In nurses with less than 5 years experience, gender, age, reported exposure to a blood-borne pathogen, and compliance with principles of prevention had a significant impact on compliance with blood-borne pathogen prevention. For nurses with more than 5 years experience, reporting after exposure to blood-borne pathogen was a contributing factor to compliance with blood-borne pathogen prevention. CONCLUSION: The study results show that to improve the implementation of preventive measures against blood-borne pathogens different strategies are needed, depending on clinical experience of the nurses.

Background and Objectives: Blood pressure (BP) measurement using an auscultatory sphygmomanometer is recommended for diagnosing hypertension in children. As mercury sphygmomanometers (MSs) are banned owing to environmental concerns, it is crucial to determine the accuracy of mercury-free sphygmomanometers to replace them. We analyzed the accuracy of these devices to guide the National Survey selection. Methods: BP was measured thrice each with MS, auscultatory device (AD), and oscillometric device (OD) in 104 participants aged 10–18 using the National Survey data. The difference in BP was defined as the difference between MS and other devices. The BP differences, correlations, and influencing factors were analyzed. The frequencies of hypertension were also compared. Results: Systolic BP (SBP) and diastolic BP (DBP) differences between MS and AD were 0.88±3.36 mmHg and 0.63±3.95 mmHg, and those between MS and OD were 0.43±5.83 mmHg and 4.57±6.89 mmHg, respectively. The absolute error of <10 mmHg for DBP between MS and OD was 76%. The concordance correlation coefficient between MS and AD was 0.94 for SBP and 0.90 for DBP, and 0.81 and 0.67, respectively for MS and OD. Arm circumference negatively correlated with BP differences except for SBP between the MS and OD. The frequency of hypertension was not different between MS and AD but was underestimated by OD. Conclusions AD correlated well with MS, while OD did not, especially for DBP. The superiority of AD over OD suggests AD as a possible alternative for MS in the National Survey.

Nonsurgical endoscopic or percutaneous dilatation and insertion of an endoprosthesis is the treatment of choice in the majority of patiens with incurabie malignant biliary obsturction. But these palliative treatment of extrahepatic cholestasis with an endoscopic or percutaneous biliary endoprosthesis is limited by clogging. One of the factors thought to be of importance is the diameter of the stent. So in order to avoid being limited by the size of the instrumentation channel of the endoscope, expandable stents have been developed. Wallstent is braided in the form of a tubular mesh from surgical grade stainless alloy. This prosthesis is geometrically stable, pliable and self expanding. Its elastic properties are such that its diameter can be substantially reduced by moderate elongation. The stent is constrainded on a small diameter delivery catheter(total outside diameter: 9 French). During the implantation procedure the final position of the partially released endoprosthesis can be adjusted by gradual removal of the delivery catheter. If full expansion to 30 French occurs, the stent will be shortened by approximately 30% to their normal length range between 34-102mm. Now in this article we report a new method for endoscopic retrograde placement of biliary Wallstent in a patient with obsturctive jaundice due to periampullary choangiocacrcinoma.

Human sperm are not only pleomorphic but also tend to show large numbers of obvious abnormalities that may be associated with infertility. It is known that the greater the numbers of abnormalities present in each sperm (teratozoospermic index) relates closely to abnormalities in sperm function and the presence of infertility. The variation in morphology that may be seen among human sperm involve the head, midpiece and tail. An oval head is deemed to be normal but many shape and size variations can be seen in an ejaculate, and these include large, small or tapering heads. Amorphous heads are now known to be associated with chromosomal anomalies and a sperm may even show the presence of a double head. Another anomaly of sperm morphology that is occasionally seen is the abnormality known as globozoospermia. In this condition, the sperm head lacks an acrosome and, as a consequence, the head of each spermatozoon becomes rounded. We have experienced a case of globozoospermia which was conceived by intracytoplasmic sperm injection. So we report this case with a brief review of literatures.
