It has been suggested that bilirubin has an inverse association with cardiovascular disease (CVD) due to its antioxidant properties. However, there are few data regarding the relationship between serum total bilirubin (sTB) and risk factors for CVD in Koreans. This study aimed to evaluate the relationship between sTB and high sensitivity C-reactive protein (hsCRP), which is an independent risk factor for CVD.
We performed a cross sectional study in 6,800 men who were examined at a health promotion center at a university hospital in Korea between May 2005 and June 2006. We grouped the subjects according to values of serum hsCRP (above or below 1.0 mg/L) and compared the characteristics of the two groups. To evaluate the relationship between sTB and hsCRP, we classified the subjects according to quartile values of sTB. Multivariate logistic regression analyses were used to analyze the relationship of levels of sTB and hsCRP after adjusting for known risk factors for CVD.
Serum hsCRP was significantly associated with body mass index (BMI), smoking, diabetes, hypertension, fasting plasma glucose, systolic blood pressure, alanine aminotransferase, and total cholesterol/high density lipoprotein (TC/HDL-C) ratio, but not with age or alcohol use. As levels of sTB increased, there was a decrease in age, numbers of smokers, BMI, and TC/HDL ratio. Compared to the lowest quartile of sTB, levels of hsCRP decreased with odds ratios of 0.82 (95% CI, 0.71 to 0.96), 0.75 (95% CI, 0.65 to 0.88), and 0.63 (95% CI, 0.54 to 0.74) in the 2nd, 3rd, and 4th quartiles of bilirubin, respectively.
Bilirubin may be inversely associated with hsCRP

The aim of this study was to investigate the relationship between heart rate variability (HRV), the Framingham risk score (FRS), and the 10-year risk of coronary heart disease (CHD) development among Korean adults.
The subjects were 85 healthy Korean adults recruited from a health check-up center. The FRS and 10-year risk of CHD development were calculated.
The FRS in men was inversely correlated with the standard deviation of all normal to normal RR-intervals (SDNN); the root mean square successive difference (RMSSD); the percentage of successive normal cardiac inter-beat intervals greater than 20 ms, 30 ms, and 50 ms (pNN20, pNN30, pNN50); the low frequency (LF); and the high frequency (HF) (P < 0.05). There was no significant relationship between the FRS and HRV in women. Overall, in the receiver operating characteristic (ROC) analysis, the RMSSD, HF, SDNN, LF, LF/HF ratio, and pNN30 predicted an increased 10-year CHD risk. After adjusting for sex and body mass index, those with greater than one standard deviation in the RMSSD, HF, and LF had a 52-59% reduction in their 10-year risk of CHD development ≥ 10%.
This study therefore indicates that the HRV indices, particularly SDNN, RMSSD, pNN30, LF, and HF may be useful parameters for the assessment of CHD risk. Most notably, the usefulness of these HRV measures as indicators for CHD risk evaluation may be greater among men than among women.

Recently, a revised telehealth legislation that allows direct doctor to patient teleconsultation was proposed in Korea. However, there have been some debates. This study aimed to examine the attitude of primary care physicians towards telehealth.
A questionnaire asking attitude towards telehealth and revised telehealth legislation was self-administered to 1,988 registered members of Practitioners Council of Korean Academy of Family Medicine. A total of 218 complete responses by family physicians were included in the study.
Large proportion (60.6%) of participants disagreed to the main clause of revised telehealth legislation, which allowed doctor to patient teleconsultation. Participants tended to expect that negative outcomes are more likely to occur than positive outcomes after the enforcement of the revised telehealth legislation. Around 50% of participants had an intention to adopt telehealth just as soon (4.6%) or afterwards (45.4%). The majority of participants suggested that; primary care clinic as the most appropriate telehealth facility (75.4%); patients with low accessibility to medical care (74.3%) as the best target of telehealth service; and tele-radiology (61.9%) or tele-pathology (41.3%) as the most applicable medical field for telehealh service. Around 89% of participants suggested telehealth service fee to be similar or higher than current medical consultation fee.
The majority of family physicians participating in this study were not in favor of the revised telehealth legislation. However, the majority of the participants had an intention to adopt telehealth to their practice and held clear opinion about practical aspects of telehealth.

In-training examination (ITE) is a cognitive examination similar to the written test, but it is different from the Clinical Practice Examination of the Korean Academy of Family Medicine (KAFM) Certification Examination (CE). The objective of this is to estimate the positive predictive value of the KAFM-ITE for identifying residents at risk for poor performance on the three types of KAFM-CE.
372 residents who completed the KAFM-CE in 2011 were included. We compared the mean KAFM-CE scores with ITE experience. We evaluated the correlation and the positive predictive value (PPV) of ITE for the multiple choice question (MCQ) scores of 1st written test & 2nd slide examination, the total clinical practice examination scores, and the total sum of 2nd test.
275 out of 372 residents completed ITE. Those who completed ITE had significantly higher MCQ scores of 1st written test than those who did not. The correlation of ITE scores with 1st written MCQ (0.627) was found to be the highest among the other kinds of CE. The PPV of the ITE score for 1st written MCQ scores was 0.672. The PPV of the ITE score ranged from 0.376 to 0.502.
The score of the KAFM ITE has acceptable positive predictive value that could be used as a part of comprehensive evaluation system for residents in cognitive field.

Metabolic syndrome has been reported to have adverse effects on cognitive function, although the results are conflicting. The purpose of this study was to examine the relationship between metabolic syndrome and cognitive function in elderly Korean participants older than 60 years.
We examined elderly participants who visited the health promotion center in Gyeonggi-do province. We categorized the participants into two groups based on the presence of metabolic syndrome (48 participants in the metabolic syndrome group and 45 in the control group). Cognitive function was assessed in all participants using the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K).
Compared with those without metabolic syndrome, participants with metabolic syndrome had lower mean total CERAD-K scores (64.2 ± 11.1 vs. 69.8 ± 9.2, P = 0.010). In the comparison of CERAD-K items, significantly lower scores were observed in the verbal fluency test, the construction recall test, the word list learning test, and trail making B in the group with metabolic syndrome. After controlling age, sex, education, smoking, alcohol, physical activity and the Korean version of the Short Geriatric Depression Scale of Korean, multiple regression analysis showed that metabolic syndrome was independently associated with cognitive function (P = 0.014). Alcohol intake (P = 0.002) and education years (P = 0.001) were also contributing factors to cognitive function.
This study found a significant relationship between cognitive function and metabolic syndrome. It will be necessary to perform a prospective study to determine whether metabolic syndrome causes cognitive dysfunction or if the correction of metabolic syndrome can improve cognitive function.

Malakoplakia is an uncommon but distinctive type of chronic granulomatous inflammation that occurs most commonly in the genitourinary tract, especially the urinary bladder. Most patients have associated conditions characterized by some degree of immunosuppression, as seen in solid-organ transplants, autoimmune diseases requiring steroid use, chemotherapy, chronic systemic diseases, alcohol abuse and poorly controlled diabetes. We report an unusual case of the renal malakoplakia that involved the perirenal space, extending to the descending colon in a 65-year-old Korean woman with secondary adrenal insufficiency and diabetes mellitus.
