Gender Difference of the Association between Energy Intake Expenditure Balance and Depression among Korean Adults: A Cross-Sectional Study from the 2014, 2016, and 2018 Korea National Health and Nutrition Examination Survey / 가정의학회지

Background@#Diet and physical activity are key factors related to depressive mood. Previous studies have demonstrated the effects of diet and physical activity on depression. However, the effect of energy intake-expenditure balance (EIEB) on mental health has not been fully evaluated. This study aimed to analyze the association between EIEB and depression. @*Methods@#A total of 13,460 participants (5,660 men and 7,800 women) aged ≥19 years were obtained from the 2014, 2016, and 2018 Korea National Health and Nutrition Examination Survey (KNHANES). EIEB was defined as the difference between the daily energy intake and energy expenditure. Energy intake was calculated and provided by the KNHANES using a 24-hour recall survey. Energy expenditure was estimated as the sum of basal metabolic rate and physical activity. Logistic regression analyses were used to investigate the association between sex-specific quartile groups (Q1–Q4) of EIEB and depression after adjusting for socioeconomic status, body mass index, lifestyle factors, and underlying diseases. @*Results@#Women in Q3 of EIEB (211–669 kcal) had a significantly lower risk of depression (odd ratio [OR], 0.78; 95% confidence interval [CI], 0.67–0.92) than those in Q1 of EIEB (<-167 kcal). The adjusted ORs of depression were 0.87 (95% CI, 0.75–1.02) in Q2 and 0.86 (95% CI, 0.74–1.01) in Q4, with P for trend=0.030. There were no significant associations between the EIEB quartile groups and depression in men after adjusting for potential confounders (P for trend=0.564). @*Conclusion@#Our results suggested that the EIEB is negatively associated with depression in Korean women.

Analysis of Continuity of Care and Its Related Factors in Diabetic Patients: A Cross-Sectional Study / 가정의학회지

Background@#Continuity of care in primary care settings is crucial for managing diabetes. We aimed to statistically define and analyze continuity factors associated with demographics, clinical workforce, and geographical relationships. @*Methods@#We used 2014–2015 National Health Insurance Service claims data from the Korean registry, with 39,096 eligible outpatient attendance. We applied multivariable logistic regression to analyze factors that may affect the continuity of care indices for each patient: the most frequent provider continuity index (MFPCI), modified-modified continuity index (MMCI), and continuity of care index (COCI). @*Results@#The mean continuity of care indices were 0.90, 0.96, and 0.85 for MFPCI, MMCI and COCI, respectively. Among patient factors, old age >80 years (MFPCI: odds ratio [OR], 0.81; 95% confidence interval [CI], 0.74–0.89; MMCI: OR, 0.84; 95% CI, 0.76–0.92; and COCI: OR, 0.81; 95% CI, 0.74–0.89) and mild disability were strongly associated with lower continuity of care. Another significant factor was the residential area: the farther the patients lived from their primary care clinic, the lower the continuity of diabetes care (MFPCI: OR, 0.74; 95% CI, 0.70–0.78; MMCI: OR, 0.70; 95% CI, 0.66–0.73; and COCI: OR, 0.74; 95% CI, 0.70–0.78). @*Conclusion@#The geographical proximity of patients’ residential areas and clinic locations showed the strongest correlation as a continuity factor. Further efforts are needed to improve continuity of care to address the geographical imbalance in diabetic care.

Analysis of the Comprehensiveness of Primary Care Clinics in Korea / 가정의학회지

Background@#In the Republic of Korea, which medical specialties should take the responsibility for primary care and what the role of primary care should be are still unclear. In this study, we focused on the comprehensiveness of primary care to identify related factors. @*Methods@#The National Health Insurance Service (NHIS)-National Sample Cohort is a population-based cohort, sampled in the 2002 NHIS database and followed up until 2015. We used data collected from January 2014 to December 2015, including 20,423,832 outpatient visits in 19,557 office-based clinics. The Korean government has designated 52 simple or minor disease groups (SMDGs) to enhance the experience of patients who attend primary care for managing those diseases. We assessed comprehensiveness for each clinic as the number of SMDGs treated in each clinic for 2 years. We also identified the factors related to higher comprehensiveness, using logistic regression for analysis. @*Results@#The clinics included in the study had provided treatment for an average of 14 SMDGs during a 2-year period. Compared to general practitioners, internal medicine physicians presented higher comprehensiveness with an odds ratio (OR) of 2.29 (95% confidence interval [CI], 2.03–2.59), and family medicine physicians illustrated higher comprehensiveness (OR, 4.96; 95% CI, 3.59–6.83). Other specialties showed lower comprehensiveness than general practitioners. Clinics located in the capital city and metropolitan area tended to have lower comprehensiveness. Clinics hiring more doctors and having hospitalization facility showed higher comprehensiveness. @*Conclusion@#General physician, internal medicine, and family medicine are the fields providing comprehensive medical care in Korea. Clinics located in metropolitan area and capital city show lower comprehensiveness. The number of physicians is related to higher comprehensiveness of clinics.

Association between Risk of Metabolic Syndrome and Stress in Each Occupational Group of KoreanWorkers: Korea National Health and Nutrition Examination Survey 2014–2016

Background@#Chronic stress at work is known to be associated with the risk of developing metabolic syndrome. Recent studies have evaluated stressand its association with metabolic syndrome in specific occupational groups. In the present study, we examined the relationship between stress andthe risk of developing metabolic syndrome in each occupational group. @*Methods@#The present study examined 7,460 Korean workers, aged 20–65 years, whose data were collected from the Korea National Health andNutrition Examination Survey conducted between 2014 and 2016. The information on usual stress awareness was self-reported, and thebiochemical profile of the blood was conducted. The chi-square test and multiple logistic regression analysis were used to investigate therelationship between stress and metabolic syndrome in each occupational group. @*Results@#The metabolic syndrome was prevalent in 26.3% of the study subjects. In the function-related job groups, the individuals with high stress levelsshowed a significantly higher risk of developing metabolic syndrome (odds ratio, 1.625; 95% confidence interval, 1.042–2.534) than those with lowstress levels. An increasing trend was observed, which suggested the increased risk of developing metabolic syndrome across increasing stress levelsin a stratified analysis in many occupational groups, specifically in function-related, viz., manager and expert, office worker, service worker, andsimple laborer (P for trend <0.001) groups. @*Conclusion@#The stress levels were significantly correlated with the risk of developing metabolic syndrome in function-related job groups. A differencebetween dose-response association of stress levels and metabolic syndrome existed in each occupational group.

Hunter syndrome is one of the mucopolysaccharidoses, characterized by abnormal accumulation and deposition of mucopolysaccharides in the tissues of several organs which are known to complicate anaesthetic and airway management. We experienced a case of pulmonary edema which developed during induction of general anesthesia of Hunter syndrome after several attempts of intubation and airway obstruction.

Effects of Intravenous Induction Drugs on Intubation Conditions Using Rocuronium for Rapid Sequence Induction / 대한마취과학회지

BACKGROUND: We assessed the effect of intravenous induction agents on intubation conditions and hemodynamic changes when using rocuronium 0.7 mg/kg for rapid sequence induction. METHODS: Sixty ASA class I or II patients undergoing elective surgery were divided into a thiopental group (5 mg/kg, n = 20), a propofol group (2 mg/kg, n = 20) and an etomidate group (0.2 mg/kg, n = 20). Anesthesia was induced with intravenous induction agents. After loss of consciousness, rocuronium 0.7 mg/kg was injected. Intubation was attempted at 60 seconds after rocuronium administration. Arterial blood pressure and heart rate were measured before induction, immediately after intubation, and 1, 3, 5, and 10 minutes after intubation. Intubation conditions were assessed by jaw relaxation, vocal cord movement, response to tracheal intubation, and were evaluated as excellent, good, fair, and poor. RESULTS: Excellent intubation conditions were obtained 55% (n = 11) in the thiopental group, 60% (n = 12) in the propofol group, and 45% (n = 9) in the etomidate group. Systolic and diastolic arterial blood pressures were elevated after intubation in all three groups. But these changes were minimal in the propofol group. CONCLUSIONS: Intubation conditions were not significantly different after the intravenous injection of thiopental 5 mg/kg, propofol 2mg/kg, or etomidate 0.2 mg/kg when using rocuronium 0.7 mg/kg for rapid sequence induction.

Blood Pressure Difference between Right and Left Arms of Some College Freshmen

BACKGROUND: Hypertension is a main cause of heart blood vessel disease. To diagnose and treat hypertension, it is necessary to measure blood pressure accurately. There are various factors that influence blood pressure. According to real clinical demonstrators and some recent studies, blood pressure differences between right and left arms are often observed. This study was intended to know whether the differences are really found and wheather the correlation exists between mid-arm circumferences and the blood pressure differences according to right-handed or left-handed which were considered as an important factor in affecting blood pressures. METHODS: One hundred sixty nine college freshmen of year 2001 were chosen. Among them, 103 were right- handed and 66 left-handed. Which arms to be checked first were determined randomly. This sequence was repeated two times on each person. Their mid-arm circumferences were measured, also. RESULTS: For right-handed persons, systolic blood pressure in right arm (119.2+/-12.3 mmHg) was significantly higher than in left arm (118.0+/-12.0 mmHg) (P<0.005). But diastolic blood pressure differences between right arm (75.3+/-10.0 mmHg) and left arm (75.0+/-9.5 mmHg) was not significant statistically. For left-handed persons, systolic blood pressure was 120.3+/-9.9 mmHg in right arm and 120.0+/-10.3 mmHg in left arm. However, diastolic blood pressure in right arm (76.7 9.4 mmHg) was significantly higher than in left arm (75.0+/-8.6 mmHg) (P<0.005). For right handed persons, their arm circumferences (26.2+/-2.8 cm) were significantly thicker than left ones (25.9+/-2.9 cm). For left-handed, left arm circumference (25.9+/-2.7 cm) was significantly thicker than right one (25.5+/-2.6 cm). As for the blood pressure difference in arm tested order, the first measured systolic blood pressure (right arm; 120.9+/-11.7 mmHg, left arm; 120.0+/-11.9 mmHg) was significantly higher than the second measured one (right arm; 118.3+/-11.8 mmHg, left arm; 117.8+/-11.6 mmHg) (P<0.005). However, the first measured diastolic blood pressure (right arm; 76.3+/-10.5 mmHg, left arm; 75.5+/-9.4 mmHg) did not have more significance than the second measured one (right arm; 75.4+/-9.9 mmHg, left arm; 74.6+/-10.8 mmHg). CONCLUSION: The right-handed person's blood pressure was higher in the right arm, but for the left-handed persons it was not significantly different in both arms. The second measurement of blood pressure was lower than the first measurement in both arms. The arm circumference depending on the right/left-handedness influenced the blood pressure, but clear correlation between them was not observed. Therefore, if possible, when the blood pressure is measured, it is advised to check blood pressure in both arms before diagnosing hypertension.

A Study on the Applications of super-Impose ID Image System / 대한의료정보학회지

In this paper, a new superimposition scheme using a computer vision system was proposed with pairs of skull and ante-mortem photographs, which were already identified through other tests and DNA fingerprints at the Korea National Institute of Scientific Investigation. In this computer vision system, an unidentified skull was caught by video-camcoder with the MPEG and the other ante-mortem photograph was scanned by scanner. These two images were processed and superimposed using pixel processing. This recognition of individual identifications by anatomical references can be performed on the two superimposed images for many big cases like as Guam KAL accident in 1997.
