To investigate retinal hemodynamics in diabetic retinopathy, the perifoveral capillary leukocyte velocity for retinal microcirculation was measured in eyes of 16 control. 12 non-proliferative diabetic retinopathy(NPDR) and 10 proliferative diabetic retinopathy(PDR) on the video fluorescein angiogram using a scanning laser ophthalmoscope(SLO 101, Rod-enstock, Munich, Germany) in 20 degrees retinal field. And the times of arm to retinal circulation, arterio-venous circulation and venous lamina flow for retinal macrocirculation were also measured in eyes of 18 control, 16 NPDR and 10 PDR in 40 degrees retinal field. There was not any statistically significant difference between control eyes(140.62 +/- 34.11 pixels/see, 1.21 +/- 0.29 mm/sec) and NPDR eyes(133.98 +/- 31.85 pixels/sec, 1.15 +/- 0.27 mm/sec) in mean perifoveal capillary leukocyte velocity(p=0.60). But it was significantly decreased in PDR eyes(108.80 +/- 26.19 pixels/see, 0.94 +/- 0.23 mm/sec) compared with control(p=0.01) and NPDR eyes(p=0.05). The were not any significant differences in the times of arm to retinal and arterio-venous circulation respectively(p>0.05) among the eyes of control(12.09 +/- 1.41 sec, 2.41 +/- 0.86 sec), NPDR(12.66 +/- 1.42 see, 2.32 +/- 0.96 sec) and PDR(12.90 +/- 1.51 see, 2.54 +/- 0.94 sec). But the venous lamina flow time was significantly decreased in eyes of NPDR(6.91 +/- 2.32 see, p=0.02) and PDR(7.03 +/- 1.89 sec, p=0.01) compared with that of control(5.46 +/- 1.18 see). These results indicate that a significant retinal microcirculatory deficit exists in the eyes of PDR, and venous lamina flow time may be a good index of retinal macrocirculatory deficit in diabetic retinopathy.

PURPOSE: Metabolic Syndrome (MetS) is defined as a cluster of inter-connected metabolic disorders involving the glucose metabolism, dyslipidaemia, high blood pressure, and abdominal obesity. The worldwide prevalence has been rapidly increasing to approximately 20~25%, and the prevalence in Korea as of 2012 was reported to be 31.3%. The association of MetS with various diseases needs to be analyzed by conducting an investigation of frequently consumed foods, such as dairy products, fish, and shellfish in prediabetic subjects. METHODS: The dietary intake of subjects who met the criteria of the study from January to December 2015 was assessed using the 24-hour recall method. After adjusting the age, sex, BMI, and total energy intake, which are confounding factors that may affect the dietary intake of the subjects, the associations of dairy products, fish, and shellfish intake with the MetS risk factors was analyzed. RESULTS: In prediabetes, the intake of subjects who consumed more than the dairy products median (187.0 g) and the elevation risk of TC [OR, 2.369; 95% CI, 1.057 to 5.312] showed a significant positive association. In prediabetes, the intake of subjects who consumed more than the fish and shellfish median (44.0 g) and the elevation risk of BP showed a significantly weak negative association [OR, 0.073; 95% CI, 0.010 to 0.520]. The probability that the blood LDL cholesterol was ≥ 100 mg/dL decreased 0.397 times [95% CI, 0.189 to 0.832]. CONCLUSION: To control the metabolic risk factors of pre-diabetic and vascular disease subjects, proper dairy, fish and shellfish intake will be important.

BACKGROUND: High-frequency jet ventilaion is considered a reliable technique for anesthesia and critical care including respiratory failure but there are adverse reactions such as carbon dioxide retension and dry of respiratory mucosa. The purpose of this study was to confirm the effects of combined high- frequency jet ventilation (HFJV) and converntional mechanical ventilation (CMV) on the cardiovascular system, arterial blood gases tension and mean airway pressure in 9 Korea mongrel dogs with pulmonary edema induced by oleic acid. METHODS: During CMV with 20 breaths/minute, 10 ml/kg of tidal volume and F1O2 1.0, parameers were evaluated (base line value). When pulmonary edema was developed, HFJV was applied initially with 120 breaths/minute, inspiratory time 30% and driving pressure 40 psi F1O2 1.0 for 60 minutes (control value) and thereafter simultaneous use of CMV was applied with the tidal volume of 10 ml/kg and each respiratory rate 8, 4, 2, 1, 0.5 per minute for 30 minutes. RESULTS: Combined application of HFJV and CMV (above repiratory rate 1 per minute) achieved the improvement of oxygenation and carbon dioxide elimination, and Paw was decreased without undesirable effects on cardiovascular system in case of the induced pulmonary edema. CONCUSIONS: From above results we recommanded that HFJV combined with CMV may be a useful method of treatment for respiratory failure.

This study examined the effects of a brown rice vegetarian diet and outdoor walking exercise program on body composition and blood lipid parameters in collegians. The mean age of respondents was 21.8 yrs (males) and 21.7 yrs (females). During the ten-day program, the respondents lived in a dormitory and had three meals. The respondents exercised one hour in the morning (6:20~7:20 am) and attended one and a half hour evening lecture (7:00~8:30 pm) everyday. The brown rice vegetarian diet consisted of brown rice, whole grain bread, beans, fresh vegetables, and fresh fruits contained 2043.2+/-112.7 kcal (97.3% of RNI), 66.7 g protein (133.3% of RNI), 33.6 g dietary fiber (168.2% of RNI), vitamin A (194.2% of RNI), vitamin B1 (245.5% of RNI), vitamin B2 (225.1% of RNI), niacin (233.7% of RNI), vitamin B6 (277.1% of RNI), folic acid (128.4% of RNI), vitamin C (334.6% of RNI), iron (131.9% of RNI), zinc (112.4% of RNI) and calcium (60.3% of RNI). The results showed that there were significant increases in body weight (P<0.05) and BMI (P<0.05) in males and body weight (P<0.05) and lean body mass (P<0.01) in females. In addition, there were significant decreases in total cholesterol (P<0.001), LDL cholesterol (P<0.001), TG (P<0.05), and HDL-cholesterol (P<0.001) in males and total cholesterol (P<0.01) and LDL-cholesterol (P<0.01) in female. The ten day brown rice vegetarian diet rich in fiber and outdoor walking exercise program significantly increased body weight and decreased total cholesterol and LDL-cholesterol in collegians.

PURPOSE: This study investigated the Korean social workers' burn-out factors and personal traits in hospice and palliative care field, and also examined the effect and correlation between their professionality, social support and supervision. METHODS: Data (N=46) from 46 social workers working at hospice and palliative care field were collected, and the data were analyzed for the inferential statistics using t-test, ANOVA, correlation and multiple regression with the SPSS 12.0 program. RESULTS: General factors of the burn-out were age and work experience. The effect of the organization environment is greatly dependant on social support and supervision, and the burn-out were protected when workers got an emotional support from their family. For the workers with supervision, the less negative feeling, the better for the burn-out protection. Furthermore, the low burn-out was thought about when professional organization, self regulation, job vocation and autonomy were utilized. Regression analysis needed that the burn-out were protected well when individual autonomy among expertise was guaranteed. As for social support, vertical support was able to protect physical burn-out. CONCLUSION: The training program for social workers in hospices and palliative care field is essential to reduce and prevent the burn-out. Hospice should be more activated and a training program with up-to-date knowledge and information should be adopted.

Purpose: To evaluate the clinical course of neovascular age-related macular degeneration (nAMD) that has shown limited response to ranibizumab and aflibercept. Methods: This retrospective study included 14 eyes with nAMD that showed a limited response to initial treatment using ranibizumab and aflibercept. The changes in visual acuity (VA) during the follow-up period and the incidence and timing of VA deterioration to the level of 0.1 or worse were identified. In cases involving bevacizumab treatment, the follow-up duration and the proportion of patients maintaining a VA of 0.2 or better were identified. Results: During the mean 43.3 ± 33.2 months of follow-up, the VA deteriorated significantly from a mean logarithm of minimum angle of resolution (logMAR) of 0.42 ± 0.34 at diagnosis to 0.91 ± 0.68 at the final follow-up (p = 0.021). A logMAR of 0.3 or greater degree of VA deterioration was noted in six eyes (42.9%). Among the 13 eyes exhibiting a VA of 0.2 or better after the initial treatment, a deterioration to a VA of 0.1 or worse was noted in 6 eyes (46.2%) at a mean 29.7 ± 18.3 months. In eight eyes undergoing bevacizumab treatment, four eyes (50.0%) maintained 0.2 or better VA during the 51.4 ± 35.5 months of follow-up. Conclusions The clinical course of patients with limited response to ranibizumab and aflibercept was generally unfavorable. However, a relatively long period was required for the deterioration in VA to reach 0.1 or worse. In addition, 0.2 or better VA was maintained in approximately half of the patients.

Background: The proportion of antimicrobial-resistant Enterobacteriales as a causative pathogen of community-acquired acute pyelonephritis (APN) has been increasing. The aim of this study was to quantitatively evaluate the impact of antimicrobial resistance on medical costs and length of hospital stay for the treatment of APN. Materials and Methods: A single-center retrospective cohort study was conducted between January 2018 and December 2019. All hospitalized patients aged ≥19 years who were diagnosed with community-acquired APN were recruited, and those diagnosed with Enterobacteriales as a causative pathogen were included. Log-linear regression analysis was performed to determine the risk factors for medical costs and length of hospital stay. Results: A total of 241 patients participated in this study. Of these, 75 (31.1%) and 87 (36.1%) had extended-spectrum beta-lactamase (ESBL)-producing pathogens and ciprofloxacinresistant pathogens as the causative pathogen, respectively. Based on the log-linear regression model, ESBL-producing Enterobacteriales is a causative pathogen that is, on average, 27.0%, or United States Dollar (USD) 1,211 (P = 0.026) more expensive than non-ESBL-producing Enterobacteriales. A patient who is a year older would incur USD 23 (P = 0.040) more, those having any structural problems in the urinary tract would incur USD 1,231 (P = 0.015) more, and those with a unit increase in the Pitt bacteremia score would incur USD 767 (P <0.001) more, with all other variables constant. Having a case in which ESBL-producing Enterobacteriales is a causative pathogen would explain staying 22.0% longer or 2 more days (P = 0.050) in the hospital than non-ESBL-producing Enterobacteriales. A patient who is 10 years older would, on average, would have to stay for half a day longer (P = 0.045). Any structural problems in the urinary tract explain a longer stay (2.4 days longer; P = 0.032), and moving from 0 to 5 on the Pitt bacteremia score would explain four more days (P = 0.038) in the hospital. Conclusion Patients with community-acquired APN with ESBL-producing Enterobacteriales as the causative pathogen would incur, on average, 27.0% higher medical costs and 22.0% longer hospitalization days than patients detected with non-ESBL-producing pathogens.
