BACKGROUND: The purpose of this study was to understand the level of successful aging and to analyze the factors that affect successful aging. METHODS: This study was a descriptive study. The data collection of this study using questionnaires was from October 1, 2017 to December 30, 2017, and the 169 elderly people living in Chungcheongnam-do were surveyed. RESULTS: The mean level of successful aging of the subjects was 3.57 (±0.58), which was higher than the median, it was significantly different among the presence of religion, participation in senior facility, regular exercise, pain, and subjective health status. Regression analysis showed that the factors that have the greatest influence on the successful aging of the subjects were the participation in senior facility (β=0.24, P<0.001), self-esteem support (β=0.20, P=0.024), emotional support (β=0.19, P=0.048), regular exercise (β=0.19, P=0.002), and pain (β=−0.14. P=0.029). The explanatory power of these variables on successful aging was 53% (F=20.37, P<0.001). CONCLUSIONS: This study showed that emotional support and support for self-esteem were important in successful aging, and that pain, which was not considered in previous studies, was an important factor.

Purpose: Propranolol is widely prescribed to psychiatric patients to control adrenergic symptoms. However, propranolol poisoning can be fatal due to cardiovascular complications. We analyzed associations between blood levels of propranolol and patients’ clinical features, with the aim of predicting progression to severe complications. Methods: Data were collected from patients aged 18 years or older who presented to the emergency department with propranolol poisoning between January 2016 and May 2022. We retrospectively analyzed their medical records and compared blood levels of propranolol between those who had cardiovascular complications and those who did not. Results: Two hundred patients were included in this study. The blood levels of propranolol were significantly higher in patients with hypotension, bradycardia, and prolonged QT intervals, with median values of 247.0 ng/mL (interquartile range [IQR], 56.5–333.8 ng/mL), 275.8 ng/mL (IQR, 154.3–486.4 ng/mL), and 159.0 ng/mL (IQR, 33.9–310.8 ng/mL), respectively. In the predictive analysis of cardiovascular complications using a receiver operating characteristic curve, the area under the curve was 0.729 with a cut-off value of 72.40 ng/mL (sensitivity, 0.667; specificity, 0.819). In addition, the correlation coefficient between blood levels and the amount of drug described during the history-taking at the time of presentation was 0.634, which was found to have a significantly higher relationship. Conclusion Because blood levels of propranolol can be used as predictors of exacerbation in patients with propranolol poisoning, patients with blood levels above 72.40 ng/dL require careful treatment and observation from their initial presentation at the emergency department.

PURPOSE: The aim of this study is to investigate the difference between male and female in some clinically meaningful aspects and to prevent intentional poisoning in children and adolescents. METHODS: Retrograde medical records review of patients who visited the emergency department of two secondary hospitals for drug ingestion from March 2010 through March 2013 was performed. Unintentional ingestion or ingestion by others was excluded. RESULTS: A total of 138 cases were reported, male 25.4% (n=35), female 74.6% (n=103). The reason for poisoning was intentional in 132 cases (95.7%) and misuse in six cases (4.3%). In female patients, non-prescription drugs was the most common cause of intentional poisoning (68.9%). Male patients tend to use life substances for intentional poisoning more frequently (20.0%) than female (3.9%). Seven male patients and 12 female patients had previous psychiatric history and 34.3% of male and 41.7% of female were consulted to the psychiatric department. CONCLUSION: Female adolescents are more likely to ingest drugs intentionally for suicide attempt than males of comparable ages. The drugs they ingested were, in many cases, obtained with ease from the drug store nearby and, remarkably, most of the drugs they obtained in that way were acetaminophen-containing. This suggests that some guidelines or control in the pharmacy that restrict children or adolescents from obtaining potentially or possibly life-threatening drugs might be necessary. In addition, education regarding drugs is thought to be necessary in school for teenagers as they tend to misuse them with incorrect acknowledgement.

BACKGROUND: Isoniazid(INH) and rifampicin(RFP) are the most effective anti-tuberculosis drugs which make the short-course chemotherapy possible. Although prescribed dosages of INH and RFP in Korea are different from those recommended by American Thoracic Society, there has been few study about pharmacokinetic profiles of INH and RFP in Korean patients who receive INH, RFP, ethambutol(EMB) and pyrazinamide(PZA) simultaneously. METHODS: Among the patients with active tuberculosis from Dec. 1997 to July 1998, we selected 17 patients. After an overnight fast, patients were given INH 300mg, RFP 450mg, EMB800mg and PZA 1500mg daily. Blood samples for the measurement of plasma INH(n=15) and RFP(n=17) level were drawn each at 0, 0.5, 1, 1.5, 2, 4, 6, 8 and 12hrs, and urine was also collected. INH and RFP level in the plasma and the urine were measured by high-performance liquid chromatography(HPLC). Pharmacokinetic parameters such as peak serum concentration(Cmax), time to reach to peak serum concentration(Tmax), half-life, elimination rate constant(Ke), total body clearance(CLtot), nonreanl clearance(CLnr), and renal clearance(CLr) were calculated. RESULTS: 1) Pharmacokinetic parameters of INH were as follows: Cmax; 7.63 +/- 3.20 micro gram /ml, Tmax; 0.73 +/- 0.22hr, half-life;2.12 +/- 0.84hrs, Ke;0.83 +/- 0.15hrs-1, CLtot;17.54 +/- 8.89L/hr, CLnr; 14.74 +/- 8.35L/hr, CLr; 2.79 +/- 1.31L/hr 2) Pharmacokinetic parameters of RFP were as follows : Cmax; 8.93 +/- 3.98 micro gram/ml, Tmax;1.76 +/- 1.13hrs, half-life;2.27 +/- 0.54hrs, Ke;0.32 +/- 0.08hrs-1, CLtot;14.63 +/- 6.60L/hr, CLr;1.04 +/- 1.55L/hr, CLnr;13.59 +/- 6.21L/hr. 3) While the correlation between body weight and Cmax of INH was not statistically significant (gamma=-0.514, p value >0.05), Cmax of RFP was significantly affected by body weight of the patients(gamma=-0.662, p value <0.01). CONCLUSION: In Korean patients with tuberculosis, 300mg of INH will be sufficient to reach the ideal peak blood level even in the patients over 50kg of body weight. However, 450mg of RFP will not be the adequate dose in the patients who weigh over 50~60kg.
