Purpose: The purpose of this study was to examine self care behaviors according to the risk levels of vascular complications in elderly women with hypertension. Methods: The subjects of this study were 162 women living in the community who had been diagnosed with hypertension in clinics. The data were analysed by the SPSS 10.0 program using descriptive statistics, t-test, and ANOVA with Scheff$\dot{e}$ post-hoc test. Results: The average self care behavior score of the elderly women was 2.79. Total self care behavior was significantly different depending on the risk levels of vascular complications such as systolic blood pressure, diastolic blood pressure, ankle-brachial index, and the framingham point score. Among sub-scores of self care behaviors, exercise management was the poorest performance compared with other self care behaviors. Conclusion: This study proved the differences in self care behaviors according to the risk levels of vascular complications. To decrease the prevalence of vascular complication, it is necessary to develop programs specifically to enhance self care behaviors of elderly women with hypertension.

Purpose: This study investigates the amputation rate within 1 year after the diagnosis of diabetic foot ulcer and its associated risk factors. Materials and Methods: This study enrolled 60 patients with diabetic foot ulcer. The mean and standard deviation age was $64.4{\pm}12.8years$ (range, 32~89 years); the mean and standard deviation prevalence period for diabetes mellitus was $21.0{\pm}7.5years$ (range, 0.5~36 years). The amputation rate was evaluated by dividing the subjects into two groups - the major and minor amputation groups - within 1 year following the initial diagnosis of diabetic foot ulcer. Multivariate Cox proportional hazards regression analysis was used to identify the risk factors for amputation. Results: The total amputation rate of 38.3% (n=23) was comprised of the amputation rate for the major amputation group (10.0%) and rate for the minor amputation group (23.8%). There was a high correlation between peripheral artery disease (toe brachial pressure index <0.7) and amputation (hazard ratio [HR] 5.81, confidence interval [CI] 2.09~16.1, p<0.01). Nephropathy was significantly correlated with the amputation rate (HR 3.53, CI 1.29~9.64, p=0.01). Conclusion: Clinicians who treat patients with diabetic foot complications must understand the fact that the amputation rate within 1 year is significant, and that the amputation rate of patients with peripheral artery disease or nephropathy is especially high.

Arterial stiffness(AS) is an important pathologic state of vascular injury. This study was carried out to elucidate the effect of physiological variables on brachial-ankle pulse wave velocity(BAPWV), index of AS. Four hundred adults(volunteers) participated in this study. Body indices, biochemical, cardiac and inflammatory markers, and right(Rt)- and left(Lt)-BAPWV were measured. Body mass index(BMI), Rt- and Lt-BAPWV, glucose, triglyceride, alkaline phosphatase(ALP), gamma-glutamyl transferase(GGT), creatinine, uric acid, troponin-I(TNI), NT-proBNP and high sensitivity C-reactive protein(hs-CRP) levels were higher than the reference value of each variable. Rt- and Lt-BAPWV were directly correlated with age, body weight, BMI, glucose, ketone, aspartate aminotransferase, alanine aminotransferase, ALP, GGT, total cholesterol, low density lipoprotein, lipoprotein(a), apolipoprotein-B, blood urea nitrogen, heart rate, TNI, creatine kinase, CK-MB, lactic dehydrogenase, myoglobin, hs-CRP, lipase, reumatoid factor, fibrinogen and D-dimer (P<0.05, P<0.01, P<0.001 or P<0.000, respectively), but inversely associated with total bilirubin, uric acid, apolipoprotein-A1 and GFR (P<0.05). These observations suggest that a variety of physiological variables may influence BAPWV, resulting in increased risk or prevention of cardiovascular and/or cerebrovascular attacks. Therefore, physiological variables affecting BAPWV should be regularly controlled.

Background: A diabetic foot is the most common cause of non-traumatic lower extremity amputations (LEA). The study seeks to assess the risk factors of amputation in patients with diabetic foot ulcers (DFU). Methods: The study was conducted on 351 patients with DFUs from January 2010 to December 2018. Their demographic characteristics, disease history, laboratory data, ankle-brachial index, Wagner classification, osteomyelitis, sarcopenia index, and ulcer sizes were considered as variables to predict outcome. A chi-square test and multivariate logistic regression analysis were performed to test the relationship of the data gathered. Additionally, the subjects were divided into two groups based on their amputation surgery. Results: Out of the 351 subjects, 170 required LEA. The mean age of the subjects was 61 years and the mean duration of diabetes was 15 years; there was no significant difference between the two groups in terms of these averages. Osteomyelitis (hazard ratio [HR], 6.164; 95% confidence interval [CI], 3.561-10.671), lesion on percutaneous transluminal angioplasty (HR, 2.494; 95% CI, 1.087-5.721), estimated glomerular filtration rate (eGFR; HR, 0.99; 95% CI, 0.981-0.999), ulcer size (HR, 1.247; 95% CI, 1.107-1.405), and forefoot ulcer location (HR, 2.475; 95% CI, 0.224-0.73) were associated with risk of amputation. Conclusion: Osteomyelitis, peripheral artery disease, chronic kidney disease, ulcer size, and forefoot ulcer location were risk factors for amputation in diabetic foot patients. Further investigation would contribute to the establishment of a diabetic foot risk stratification system for Koreans, allowing for optimal individualized treatment.

Increasing fat tissue of obese people, increases the rate of cardiovascular disease, diabetes, metabolic syndromes and dyslipidemia. An increase in the focal tissue of pancreas is a known risk factor of these diseases. Although there exists sufficient research on the diagnosis and treatment of pancreatic cancer, studies have been done on fatty pancreas. In this study, based on ultrasound imaging and using a texture characteristic of GLCM, fatty pancreas was divided into three categories: mild, moderate and severe. We compared and analyzed the three groups was by Pancreatic ultrasonography and body characteristics, serological tests, pressure and the degree of arteriosclerosis, against normal control group. The following parameters of control and test groups were measured: WC (waist circumference),BMI (body mass index), TC (total cholesterol), TG (triglyceride), HDL-C (High-density lipoprotein cholesterol) and LDL-C (Low-density lipoprotein cholesterol), SBP (systolic blood pressure), BST (Blood Sugar Test) and aortic PWV (pulse wave velocity). We observed the values correspondingly increasing fat deposition. However, ABI (Ankle Brachial pressure index) stenosis and HDL-C levels decreased with increasing fat deposit (p <0.05); a drop in these parameters are known to be harmful to the human body. The difference in texture characteristics between normal control group and pancreatic fatty group (mild, moderate, and severe) was statistically confirmed. Ultrasound imaging of pancreatic steatosis categorized the disease as mild, moderate and severe based on the characteristic texture. In conclusion, we observed on increase in metabolic syndrome, dyslipidemia, and arteriosclerosis, proportional to the degree of pancreatic fat deposition. The escalation of these diseases was confirmed and was directly related with predictors of cardiovascular diseases.

목 적 : 레닌-안지오텐신계가 혈압 조절에 있어서 핵심적인 역할을 한다는 것은 이미 잘 알려진 사실이며, 이 체계의 한 구성 요소인 angiotensinogen을 암호화하는 유전자가 고혈압의 유전적 감수성을 결정하고 심혈관계 합병증 발생에 중요한 역할을 할 것으로 생각된다. 본 연구의 목적은 고혈압 청소년에서 angiotensinogen 유전자 다형을 분석하고, 특정 유전자형이 심혈관계 합병증의 예측 인자가 될 수 있는지를 알아보고자 하였다. 방 법 : 16세에서 17세 사이의 수축기 혈압 140 mmHg 이상이거나 이완기 혈압 90 mmHg 이상인 40명의 고혈압 청소년과 57명의 정상 청소년을 대상으로 하였다. 비만도, 체질량지수를 측정하였고, 안정된 상태에서 수축기, 이완기 혈압을 측정하였다. 호모시스테인, 인슐린, 레닌, 알도스테론, 안지오텐신 전환 효소(angiotensin convering enzyme, ACE)를 측정하였고, polymerase chain reaction (PCR)을 이용하여 angiotensinogen (M235T) 유전자형을 분석하였다. 경부 초음파로 경동맥 내중막 두께와 경동맥 직경을 측정하였고, 이를 이용하여 경동맥의 유순도와 신전도를 구하였다. VP-1000을 이용하여 pulse wave velocity (PWV)와 ankle-brachial index (ABI)를 측정하였다. 유전자 다형별로 각 계측치를 비교, 분석하였다. 결 과 : Angiotensinogen 유전자 다형 분석에서 T/T 군 25명(62.5%), M/T 군 14명(35%), M/M 군 1명(2.5%)로 정상 청소년과 유의한 빈도의 차이가 없었다. 고혈압군에서 인슐린, 레닌, 체질량지수, 비만도에서 세 유전형군 간의 유의한 차이가 나타났으나, 경동맥 내중막 두께와 직경, 신전도, 유순도, PWV, ABI에서는 세군 간의 유의한 차이는 없었다. 결 론 : Angiotensinogen의 특정 유전자 다형과 심혈관계 합병증간의 유의한 연관성은 없었으나, 본 연구의 고혈압 청소년 대상이 적었으므로 더 많은 연구가 필요할 것으로 생각된다.

신체조성과 혈관탄성의 변화로 인한 심혈관질환과 근감소로 인한 낙상의 발생은 노화로 인하여 가장 빈번하게 발생하게 된다. 그래서 탄력밴드 저항운동은 노인들이 쉽고 안전하게 수행할 수 있으며 신체조성과 혈관탄성에 긍정적인 영향을 미칠 수 있을 것이다. 따라서 본 연구는 고령여성(>65 years)을 대상으로 12주간 저항운동을 실시한 후 신체조성, 혈관탄성, 낙상위험도지수에 어떠한 효과를 미치는지에 대하여 살펴보았다. 저항운동은 주3회 한 회당 60분으로 구성되었고 운동 강도는 Borg의 운동자각도(6 - 20)에서 11-14로 설정되었다. 신체조성에 해당하는 체중, 근육량, 체지방률, BMI(Body Mass Index)와, 혈관탄성(맥파속도 (Pulse wave velocity (PWV)), 낙상위험도지수(Risk of falling)는 훈련 전과 후에 측정이 되었다. 연구 결과 신체조성에서 운동집단의 체중(p=.003), BMI(p=.002), PWV(p=.017), 낙상위험도지수(p=.037)는 유의하게 감소하였으나 통제집단에서 체중(p=.009), BMI(p=.009)는 유의하게 증가하였다. 따라서 여성노인들은 탄력밴드 저항운동을 통해 체중과 BMI를 감소시키고 혈관탄성에 긍정적인 효과를 얻게 되었다. 그리하여 탄력밴드 저항운동은 노인들의 대사증후군, 심혈관질환, 낙상사고의 발생률을 낮출 수 있는 매우 효과적인 운동이라 할 수 있다.

Purpose: Diabetic foot gangrene has a high morbidity rate and a great influence on the quality of life. Amputation is an appropriate treatment if conservative treatment is impossible according to the severity of gangrene and infection. The purpose of this study was to evaluate the usefulness of preoperative percutaneous transluminal angioplasty for the postoperative outcome. Materials and Methods: From February 2013 to April 2016, among 55 patients with diabetic foot gangrene, who require surgical treatment, percutaneous transluminal angioplasty was performed on patients with an ankle brachial index (0.9 and stenosis) 50% on angiographic computed tomography. The study subjects were 49 patients, comprised of 37 males (75.5%) and 12 females (24.5%). The mean age of the patients was $70.0{\pm}9.6years$. The treatment results were followed up according to the position and length of the lesion and the changes during the follow-up period. Results: As a result of angiography, there were 13 cases of atherosclerotic lesions in the proximal part, 11 cases in the distal part and 25 cases in both the proximal and distal parts. As a result of the follow-up after angiography, in 13 patients, the operation was not performed and only follow-up and dressing were performed around the wound. Sixteen patients underwent debridement for severe gangrene lesions and 20 patients, in whom the gangrene could not be treated, underwent amputation (ray amputation or metatarsal amputation, below knee amputation). Conclusion: Preoperative percutaneous angioplasty in diabetic foot gangrene patients with peripheral vascular occlusive disease is simple, and 59.2% of the patients with diabetic foot gangrene could be treated by conservative treatment or debridement.
