We present electrophysiological (EP) signals correlated with cellular cell activities in the adrenal cortex and medulla using an adrenal gland implantable flexible EP probe. With such a probe, we could observe the EP signals from the adrenal cortex and medulla in response to various stress stimuli, such as enhanced hormone activity with adrenocorticotropic hormone, a biomarker for chronic stress response, and an actual stress environment, like a forced swimming test. This technique could be useful to continuously monitor the elevation of cortisol level, a useful indicator of chronic stress that potentially causes various diseases.
Most Korean patients with non-insulin-dependent diabetes mellitus (NIDDM) have been reported not to be obese, and many of them lost weight significantly during the course of their disease. In this regard, a retrospective cohort study was conducted to determine the relationship between body mass index (BMI, kg/m2) and the risk for NIDDM among Koreans. Subjects who had received a medical examination from 1990 to 1991 and who were available for the detection of NIDDM until September 1999 were included. Subjects who initially had diabetes or were diagnosed as diabetic within 1 yr after enrollment were excluded. We reviewed the medical records of final cohort of 2,531 subjects. Follow-up of this cohort revealed 117 cases with diabetes with an incident of 7.8 per 1,000 person-years. Compared with those with BMI less than 23 kg/m2, the adjusted relative risks for diabetes mellitus for those with BMI of 23-24.9, 25-26.9, and greater than 27 kg/m2 were 0.85 (0.47-1.50), 1.29 (0.72-2.31), and 3.38 (1.22-4.63), respectively, for men (p for trend<0.01) and as for 9.14 (1.99-41.8), 7.36 (1.47-36.8), and 14.5 (3.03-69.2), respectively, for women (p for trend<0.01). These data indicate a direct relationship between obesity and the risk for the development of diabetes, emphasizing the importance of weight control for the prevention of NIDDM in Koreans.
Objective:Hypercholesterolemia is a major risk factor for cardiovascular disease and requires continuous management. The role of primary physicians in this regard is important, yet the factors associated with successful lipid lowering treatments in primary clinics have not been clearly identified. We aimed to evaluate the rate of successful hypercholesterolemia treatment in Korean primary care, and to identify the factors associated with achieving low density lipoprotein cholesterol (LDL-C) targets.Methods:We prospectively recruited and retrospectively assessed 1851 Korean patients with hypercholesterolemia who visited family physicians and were prescribed rosuvastatin for the first time. LDL-C lowering targets, defined according to NCEP ATP III guidelines, were evaluated at 6 months after the first prescription. The factors associated with achieving these targets were also assessed.Results:Overall, 87.6% of our participants attained their LDL-C goals. In multiple logistic regression analysis, good adherence to medication was strongly associated with the achievement of target LDL-C levels, whereas higher cardiovascular risk factors including diabetes (in both sexes), low high density lipoprotein, and current smoking status (in males), and hypertension (in females) were related to LDL-C target level failures.Conclusion:Our observations of the short period for hypercholesterolemia in Korean primary care has revealed that the rate of achieving target LDL-C levels was high in these patients, whereas patients at higher risk for cardiovascular disease tended to have lower LDL-C achievement outcomes. Primary care physicians should pay more attention to patients showing higher cardiovascular risk and stress the need for good adherence and management regimens in these individuals.
Korean Lifetime Health Maintenance Program (KLHMP) represents one of several efforts to take a more evidence-based approach to the development of recommendations on a wide range of preventive services.This paper summarizes the methods of the third KLHMP developed by Korean Academy of Family Medicine.The review process of KLHMP was mainly based on trans contextual guideline adaptation of United States preventive service Task force (USPSTF) recommendation.The method of review process was done according to categories of recommendation (adotion of USPSTF's recommendation, adatation of USPSTF's recommendation, development of new recommendation).If the recommendation done by USPSTF is up to date and acceptable in Korean context, it was translated and adopted.If the USPSTF recommendation was not up to date, nor applicable, the recommendation was drawn by adaptation process.If the condition has not been reviewed by
Although several studies have individually investigated the risk factors for erectile dysfunction (ED), premature ejaculation (PE), and late-onset hypogonadism (LOH), few studies have considered ED, PE, and LOH as categories of sexual dysfunction (SD) within the same population. We therefore aimed to investigate the prevalence of SD and its associated risk factors among men in primary care. Study participants were enrolled by 18 family physicians from 15 hospital-based family practices in Korea between August 2010 and May 2011. Participants answered a questionnaire regarding their demographic characteristics and lifestyle factors as well as the Korean versions of the Androgen Deficiency in the Aging Male, the International Index of Erectile Function, and the Premature Ejaculation Diagnostic Tool questionnaires. SD prevalence was 64.9% among study participants who were ≥ 40 years of age. ED prevalence was 43.7%, PE prevalence was 38.6%, and LOH prevalence was 16.8%. SD prevalence was significantly associated with increased age, overweight, hypertension, diabetes, and depression. These findings highlight the importance of screening questions for SD in primary care, especially among older male patients with the identified risk factors.

Programs that promote health through schools (school health programs), when delivered through schools that are themselves organized to promote health (health-promoting schools), are one of the essential means through which the twin goals of "Health for All by the Year 2000" and "Education for All" can be achieved. There are numerous evidences that school health programs are cost-effective and highly beneficial for adolescents themselves and communities they are belonged to. These days, the world's trend for school health programs has two directions. One is that to achieve best goals for school health, well - organized efforts are needed from governments, communities, schools, parents, and doctors. So, a new concept of 'comprehensive school health programs' is emerging. The other is that physicians should play an active roles not only for the school health promotion and school health education but also for the other steps including making policies, and advising community members who are concerned with school health services. Now, it is also time for Korean doctors to be an advocate for comprehensive school programmes and to participate actively in those programs.
