Background: The influence of lifestyle diseases on postoperative complications and long-term survival in patients with non-small cell lung cancer (NSCLC) is unclear. The aim of this study was to determine whether lifestyle diseases were significant risk factors of perioperative and long-term surgical outcomes in elderly patients with stage I NSCLC. Methods: Between December 1995 and November 2013, 110 patients aged 65 years or older who underwent surgical resection of stage I NSCLC at Dong-A University Hospital were retrospectively studied. We assessed the presence of the following lifestyle diseases as risk factors for postoperative complications and long-term mortality: diabetes, hypertension, chronic obstructive pulmonary disease, stroke, and ischemic heart disease. Results: The mean age of the patients was 71 years (range, 65 to 82 years). Forty-six patients (41.8%) had hypertension, making it the most common lifestyle disease, followed by diabetes (n=23, 20.9%). The in-hospital mortality rate was 0.9% (n=1). The 3-year and 5-year survival rates were 78% and 64%, respectively. Postoperative complications developed in 32 patients (29.1%), including 7 (6.4%) with prolonged air leakage, 6 (5.5%) with atrial fibrillation, 5 (4.5%) with delirium and atelectasis, and 3 (2.7%) with acute kidney injury and pneumonia. Univariate and multivariate analyses showed that the presence of a lifestyle disease was the only independent risk factor for postoperative complications. In survival analysis, univariate analysis showed that age, smoking, body mass index, extent of resection, and pathologic stage were associated with impaired survival. Multivariate analysis revealed that resection type (hazard ratio [HR], 2.20; 95% confidence interval [CI], 1.08 to 4.49; p=0.030) and pathologic stage (HR, 1.89; 95% CI, 1.02 to 3.49; p=0.043) had independent adverse impacts on survival. Conclusion: This study demonstrated that the presence of a lifestyle disease was a significant prognostic factor for postoperative complications, but not of survival, in elderly patients with stage I NSCLC. Therefore, postoperative complications may be influenced by the presence of a lifestyle disease.

Objectives: Deep vein thrombosis (DVT) is a common complication among stroke patients. The implication of DVT progressing into a fatal pulmonary embolism is one of the main reasons treatment cannot be delayed. However, when there is a contradiction for anticoagulants, such intracranial hemorrhage (ICH), it is difficult to determine the course of treatment. Our team reports a case with both acute DVT and ICH who improved with herbal medicine Hyulbuchuko-tang. Methods : A patient with a variety of thrombosis risk factors (atrial fibrillation, DVT, Cb-inf with intracranial hemorrhage due to thrombolytic complications) showed classic symptoms of DVT (pain, edema, discoloration), disorientation and chest discomfort. The patient was administered Hyulbuchuko-tang three times a day for 24 days without any anticoagulants. Conservative therapy including elastic stocking and leg elevation was co-administered. Laboratory tests and extremity vascular Doppler sonography were carried out 3 times during the treatment period. Results : After our treatment period, both popliteal vein DVT and calf vein DVT were not discovered by sonography, and thrombosis derived factors (eg. D-dimer, fibrinogen) decreased. There was no sign of edema or discoloration after treatment, and the patient no longer complained of leg pain, disorientation or chest discomfort. Conclusion : From these results, we suggest that there is a positive effect of Hyulbuchuko-tang on DVT. Hyulbuchuko-tang should be considered as a treatment option when western medical procedures are unavailable.

Importance of the work-related musculoskeletal disorders (WMSDs) has been increasing in the hospital industry such as health care industry and financial industry. This study investigated in order to identify the factors like general, occupational and ergonomically characteristics of the subjects related to musculoskeletal disorders (MSDs) of physical therapists (PTs). Ergonomic tools of rapid upper limb assessment (RULA) were used for evaluation workload of the tasks. Prevalence of MSDs were 13 PTs (26.0%) for neck, 31 PTs (62.0%) for shoulder, 9 PTs (18.0%) for arm/elbow, 27 PTs (54.0%) for hand/wrist, 28 PTs (56.0%) for back, 14 PTs (28.0%) for leg/foot. The analysis of the rate of the pain intensity showed that 53.5% subjects experience moderate pain and 14.0% subjects experience severe pain. Factors which were general characteristics, for example, height, ergonomically characteristics such as 'Posture Score A' were related musculoskeletal subjective symptoms in logistic analysis (p<.05). Among physical therapists, action level of RULA were action level 2 (6.0%), action level 3 (52.0%), action level 4 (42.0%). Physical therapists were estimated one of the highest risk factor in this study. This study suggested that the need of preventive education and program for PTs (physical therapists). Comprehensive and systematic management plans should be established to include both ergonomic and sociopsychological aspects.

With the COVID-19 pandemic, there is increasing interest in anti-obesity strategies. According to the National Statistical Office, the obesity rate in Korea was 38.3% in 2020 and 37.1% in 2021. Obesity is a risk factor for several severe diseases, including stroke, heart disease, type 2 diabetes, and certain types of cancer. Pinus rigida × Pinus taeda is a hybrid of Pinus rigida Mill and Pinus taeda Linn, and its cones are considered a by-product. Although previous studies have investigated their pharmacological effects on antioxidant activity and protection against oxidative DNA damage, few researchers have explored their potential as functional natural materials. Therefore, we evaluated the anti-obesity effects of the cone of ethyl acetate fraction of P. rigida × P. taeda (ERT), specifically its ability to inhibit lipid accumulation. Our analysis showed that ERT contains phytochemicals (catechin and caffeic acid) which are known to improve immune function and inhibit cell damage. ERT inhibited lipid droplet accumulation at the cellular levels through Oil Red O staining. Furthermore, ERT suppressed the expression of adipogenic transcription factors (PPARγ and CEBP/α) as well as downstream lipogenic target genes (FAS and SREBP-1) thereby inhibiting adipogenesis. ERT also down-regulated key adipogenic markers, including aP2α, while inducing the phosphorylation of AMPK. It has been reported that PPARγ and CEBP/α are expressed in the early stages of adipose differentiation, while SREBP-1 is expressed in the late stage. Therefore, our findings suggest that ERT activates AMPK signaling pathways, which inhibits adipogenic transcription factors (PPARγ, C/EBPα, and SREBP1) and lipogenic genes (FAS and aP2α), thereby blocking lipid accumulation and preventing obesity and related disorders. ERT showed potential as a new resource for developing a functional material for anti-obesity agents.

Background and Objectives: Pathophysiological changes of right ventricle (RV) after repair of tetralogy of Fallot (TOF) are coupled with a highly compliant low-pressure pulmonary artery (PA) system. This study aimed to determine whether pulmonary vascular function was associated with RV parameters and exercise capacity, and its impact on RV remodeling after pulmonary valve replacement. Methods: In a total of 48 patients over 18 years of age with repaired TOF, pulmonary arterial elastance (Ea), RV volume data, and RV-PA coupling ratio were calculated and analyzed in relation to exercise capacity. Results: Patients with a low Ea showed a more severe pulmonary regurgitation volume index, greater RV end-diastolic volume index, and greater effective RV stroke volume (p=0.039, p=0.013, and p=0.011, respectively). Patients with a high Ea had lower exercise capacity than those with a low Ea (peak oxygen consumption [peak VO₂] rate: 25.8±7.7 vs. 34.3±5.5 mL/kg/min, respectively, p=0.003), while peak VO₂ was inversely correlated with Ea and mean PA pressure (p=0.004 and p=0.004, respectively). In the univariate analysis, a higher preoperative RV end-diastolic volume index and RV end-systolic volume index, left ventricular end-systolic volume index, and higher RV-PA coupling ratio were risk factors for suboptimal outcomes. Preoperative RV volume and RV-PA coupling ratio reflecting the adaptive PA system response are important factors in optimal postoperative results. Conclusions: We found that PA vascular dysfunction, presenting as elevated Ea in TOF, may contribute to exercise intolerance. However, Ea was inversely correlated with pulmonary regurgitation (PR) severity, which may prevent PR, RV dilatation, and left ventricular dilatation in the absence of significant pulmonary stenosis.

Limited studies are available concerning the effect of heavy metal exposure on cardiovascular diseases. As environmental pollution increases, food contamination, including heavy metal contamination of fish, also increases. However, researches based on the intake of heavy metals, cardiovascular disease, and fish intakes are inconclusive. We assessed an association of heavy metal exposure with cardiovascular disease and fish intake in a nationally representative group of general Korean adults. We used data from the combined 2008-2010 Korean National Health and Nutrition Examination Survey (KNHANES), and analyzed the data of 5,139 Koreans who participated in KNHANES. All participants were older than 20 years, and were diagnosed with stroke, ischemic heart disease, or hypertension. The mean blood cadmium, lead concentration, and mercury concentration of subjects were $1.07{\pm}0.01{\mu}g/L$, $2.49{\pm}0.02{\mu}g/dL$, and $5.19{\pm}0.08{\mu}g/L$, respectively. We used the survey logistic regression model to account for the complex sample design of the cardiovascular disease risk in order to estimate the odds ratios (OR). After adjusting for age, education, income, alcohol, smoking, and BMI, the increase of serum cadmium in blood was associated with the increase in the prevalence of hypertension. Further, the increase in blood cadmium concentration was associated with the increase of both systolic blood pressure (SBP) and diastolic blood pressure (DBP). Although higher fish intakes were significantly associated with higher blood mercury concentration (p for trend < 0.0001), fish intakes did not affect either blood cadmium or lead concentration. Comparing the highest fish intake group with the lowest intake group, the OR of hypertension was 0.31 (95% CI: 0.19-0.59) in the crude model for total fish. However, these associations were no longer significant after the adjustment for potential confounding factors. In conclusion, cadmium in blood was associated with an increased risk of hypertension in the general Korean adult population. However, we found no evidence of a clear relationship between cardiovascular disease and frequency of fish consumption.

본 연구는 급성 심근경색과 뇌졸중의 고위험군인 노인들을 위하여 마련된 일개 권역심뇌혈관질환센터의 경로당노인 교육프로그램이 급성 심근경색과 뇌졸중 경고증상에 대한 지식수준을 높이는 데에 효과가 있었는지 교육프로그램 수행 1년이 경과시점에서 평가하였다. 2012년 제주특별자치도 제주시의 11개 경로당에서 337명을 편의표집 하였는데, 과거 2010년 해당 경로당에서 진행된 교육프로그램에 참여했었던 159명은 실험군으로 하였고, 교육에 참여하지 않은 178명은 대조군으로 하였다. 경고증상을 정확히 알고 있는지를 알아보고자 두 가지 질환 각각 3개 문항씩 총 6문항에 대하여 질환 별 증상이 맞는다고 생각하는지를 폐쇄형 질문으로 물어 명목형(정확한 인지 여부)으로 구분하였으며 빈도(백분율)로 나타내었다. 참여군과 비참여군 간에 경고증상에 대한 지식수준은 유의한 차이를 나타나지 않았고, 급성 심근경색과 뇌졸중 경고증상에 대한 지식이 최고 수준인 것(우수 인지수준, 경고증상 여섯 개 모두를 정확히 인지)과 경로당노인 교육프로그램 참여여부가 관련이 없는 것으로 나타나 교육 효과는 확인할 수 없었다. 다만 우수 인지수준이 될 오즈값은 교육수준이 초등학교 졸업 이상일 경우 초등학교 미졸업(무학 및 서당)에 대해서 3.01배 높았고(3.01; 1.72-5.26), 매일 빠지지 않고 TV뉴스를 시청할 경우 6일 이하로 시청하는 것에 대해서 2.97배 높게 나타났으며(2.97; 1.68-5.23), 이들은 통계적으로 유의하였다. 참여군에서 교육 참여 이후 높아진 지식수준이 교육 후 1년 시점까지 통계적으로 유의한 차이 없이 유지되었던 것과 비참여군에서 지식수준이 참여군 만큼 높은 수준이었던 것은 교육참여와 상관없는 어떠한 교육중재적 요인을 공유하고 있음을 시사하였다. 결론적으로 심뇌혈관질환의 고위험군인 노인을 표적 선택하여 실시하는 일회적 지역사회 방문교육 대신 대중매체를 활용한 반복적 지식 전달이 효과 있음을 알 수 있었다. 일회적 지역사회 방문교육의 효과는 지역사회 노인 전체를 대상으로 하는 대중매체 보건교육 캠페인이 잇달아 수반되어야만 그 효과를 장기적으로 유지할 수 있다.

Background/Aims: The SAMe-TT₂R₂ score is used for assessing anticoagulation control (AC) quality with warfarin. However, it is hard to apply SAMe-TT₂R₂ score in Asian patients with atrial fibrillation (AF), because it has not been proven in those populations. This study aimed to validate the SAMe-TT₂R₂ score in Asian patients with AF and suggest a modified SAMe-TT₂R₂ score for this population. Methods: We analyzed 710 Korean patients with AF who were using warfarin. The AC quality was assessed as the mean time in therapeutic range (TTR). Each component of SAMe-TT₂R₂ score was evaluated for the relationship with AC. Further clinical factors that predict AC were analyzed. Identified factors were re-assorted and constructed as SA₂Me-TTR scoring system. Results: Of the components of the SAMe-TT₂R₂ score, female, age, and rhythm control were associated with AC. Heart failure and renal insufficiency were newly identified factors associated with AC. The modified SA₂Me-TTR score was reconstructed with the relevant risk factors (S, female gender, 1 point; A, age < 60 yr, 2 points; Me, medical history of heart failure, 1 point; T, treatment for rhythm control, 1 point; T, history of stroke or transient ischemic attack, 1 point; R, renal insufficiency, 1 point). The modified SA₂Me-TTR score demonstrated an excellent relationship with the grading of AC. The modified SA₂Me-TTR score ≤ 1 identified patients with good AC (hazard ratio 2.46, 95% CI 1.75-3.47). Conclusions: The modified SA₂Me-TTR score was useful for guiding oral anticoagulants selection in Asian patients with AF.
