Sorafenib, originally identified as an inhibitor of multiple oncogenic kinases, induces ferroptosis in hepatocellular carcinoma (HCC) cells. Several pathways that mitigate sorafenib-induced ferroptosis confer drug resistance; thus strategies that enhance ferroptosis increase sorafenib efficacy. Orphan nuclear receptor estrogen-related receptor γ (ERRγ) is upregulated in human HCC tissues and plays a role in cancer cell proliferation. The aim of this study was to determine whether inhibition of ERRγ with DN200434, an orally available inverse agonist, can overcome resistance to sorafenib through induction of ferroptosis. Sorafenib-resistant HCC cells were less sensitive to sorafenibinduced ferroptosis and showed significantly higher ERRγ levels than sorafenib-sensitive HCC cells. DN200434 induced lipid peroxidation and ferroptosis in sorafenib-resistant HCC cells. Mechanistically, DN200434 increased mitochondrial ROS generation by reducing glutathione/glutathione disulfide levels, which subsequently reduced mTOR activity and GPX4 levels. DN200434 induced amplification of the antitumor effects of sorafenib was confirmed in a tumor xenograft model. The present results indicate that DN200434 may be a novel therapeutic strategy to re-sensitize HCC cells to sorafenib.

The purposes of this study were 1) to review the Medical Nutrition Therapy (MNT) Act of the United States, 2) to introduce the efforts of the American Dietetic Association (ADA) to expand the Medicare coverage for MNT and 3) to provide information about the reimbursement under Medicare Part B for the cost of MNT. The MNT Act defined MNT services as “the nutritional diagnostic, therapeutic, and counseling services provided by a Registered Dietitian or nutritional professional for the purpose of managing diabetes or renal diseases”. Also, the MNT Act defined “conditions for coverage of MNT”, “limitations on coverage of MNT”, and “qualifications of MNT service provider”. To expand the coverage of Medicare to include MNT, the ADA realized the need for development of a protocol for MNT, as well as studies to evaluate the effectiveness and cost-effectiveness of the MNT protocol developed. Therefore, the ADA supported the studies to develop a strong database of scientific investigations of nutritional services. Furthermore, the ADA needed credible data that could be used by Policy makers, so the ADA contracted with the Lewin Group to if out the study to gather the additional data needed to strengthen the ADA's position. In the report of the Lewin Group, which was entitled, “The Cost of Covering Medical Nutrition Therapy under Medicare : 1998 through 2004”, it was concluded, that if coverage for MNT in the Part B portion of Medicare had begun in 1998, by 2004, approximately $ 2.3 billion would have been saved through reduced hospital spending under Part A of Medicare ($ 1.2 billion) and reduced physician visits under Part B ($ 1.1 billion) Effective January 1 2002, the US Congress extended Medicare coverage to include MNT to beneficiaries with diabetes or renal diseases. The Centers for Medicare and Medicaid Services (CMS) established the duration and frequency for the MNT based on published reports or generally accepted protocols (for example, protocols suggested by the ADA). The number of hours covered by Medicare is 3 hours for the initial MNT and 2 hours for a follow-up MM. In 2002, a Medicare coverage policy was made to define the Physician's Current Procedural Terminology (CPT) codes 97802, 97803, and 97804 for MNT.

Purpose: In this study, we performed a comparative analysis on the quality of life (QoL) in male and female chronic obstructive pulmonary disease (COPD) patients based on the 4th Korea National Health and Nutrition Examination Survey (KNHANES IV) from 2007 to 2010. Methods: We extracted the socio-demographic and clinical data of 1,218 COPD patients including 874 men and 344 women from the KNHANES IV database. Descriptive statistics and correlation test were used to analyze the data. In order to find factors associated with QoL of COPD patients, we conducted multivariate linear regression analysis. Results: Infrequency analysis, the educational level and income were lower in the female COPD patients than in the male ones. The QoL indexes including mobility, self-care, activities of daily living, discomfort, anxiety, and depression were significantly worse in the female of COPD patients than in the male ones (p<.01).Conclusion: Our study indicates that QoL of female COPD patients should be improved on the educational, economic, and healthcare aspects.

Background: The majority of deaths from cancer occur in low and middle income countries, partly due to poor public awareness of the signs and symptoms of cancer. Materials and Methods: A community based survey using the Cancer Awareness Measure (CAM) questionnaire was conducted in three different communities in Oman. Omani adults aged 18 years and above were invited to participate in the study. Results: A total of 345 responded from 450 invited participants (response rate=76.7%). The majority of respondents were unable to identify the common signs and symptoms of cancer identified in the CAM (average awareness was 40.6%). The most emotional barrier to seeking help was worry about what the doctor might find (223, 64.6%); a practical barrier was too busy to make an appointment (259, 75.1%) and a service barrier was difficulty talking to the doctor (159, 46.1%). The majority of respondents (more than 60% for seven out of ten symptoms) would seek medical help in two weeks for most signs or symptoms of cancer. Females were significantly more likely than males to be embarrassed (p<0.001), scared (p=0.001), and lack confidence talking about their symptoms (p=0.022). Conclusions: Urgent strategies are needed to improve public awareness of the signs and symptoms of cancer in Oman. This might leads to earlier diagnosis, improved prognosis and reduced mortality from cancer.

본 연구는 제6기 국민건강영양조사 자료를 이용하여 만 25세 이상 성인을 대상으로 사회경제적 특성 및 유병상태에 따른 의료서비스 이용행태를 파악하기 위한 연구이다. SPSS 23.0을 이용하여 빈도분석 및 기술적 통계분석, 일원배치분산분석, ${\chi}^2$-test, 회귀분석을 실시하였다. 연구결과는 남자보다 여자가, 65세 이상, 고졸이상, 무직이 많았고 소득분위는 모두 비슷한 수준으로 나타났다. 교육수준, 직능, 소득분위를 함께 고려한 사회경제적 상태(socioeconomic status; SES)에 대한 점수는 7-8점이 가장 많았고, 대부분 응답자의 주관적 건강상태는 보통으로 느끼고 있었다. 평균유병개수는 $1.07{\pm}1.497$개이며 외래서비스 평균이용횟수는 $0.50{\pm}.0745$회이며, 입원서비스 평균이용횟수는 $0.12{\pm}0.454$회로 외래서비스 이용횟수 보다 낮았다. 일반적 특성에 따른 유병 및 주관적 건강상태는 유의한 차이가 있었고, 연령이 높을수록, 교육수준과 직능, 소득분위 및 SES점수가 낮을수록 평균 유병개수는 많았으며 주관적 건강상태는 나쁘게 인식하였다. 현재 앓고 있는 질환에서 입원서비스는 중증일수록, 외래서비스는 만성일수록 많이 이용하는 것으로 나타났다. 즉, SES점수가 높을수록 전반적인 의료서비스의 이용이 낮았고, SES점수가 낮을수록 의료서비스의 이용은 높게 나타났다. 이와 같은 결과를 토대로 사회경제적 특성이 낮은 집단에게 질환을 예방할 수 있는 적절한 보건교육 프로그램을 개발하여 이들이 질환에 노출되었을 때 적정한 의료서비스를 이용할 수 있도록 지역사회기반의 적절한 보건서비스 체계의 구축 및 시행의 필요성을 시사 할 수 있겠다.

Objectives: This study was performed to identify the level of health literacy and to investigate the relationship between the health literacy and preventive health care use in middle-aged adults in Korea. Methods: A total of 315 adults aged 40 to 64 years living in Seoul participated in the study. Data were collected from December 15-24, 2010 from outpatient hospitals, clinics, workplaces and other locations in the community. Health literacy was measured using the Functional Health Literacy and Self-rated Health Literacy Questionnaires. Preventive health service use was defined as receiving screening (general health checkups, gastric and colorectal cancer, mammogram, and pap smear) and influenza vaccination. Descriptive analysis, t-test, and ANOVA were used. Results: The mean of functional health literacy was 3.87 (score range 0-6) and the self-rated health literacy was 60.08 (score range 16-80). The most difficult items of the self-rated questionnaires were patient educational materials provided by health care providers and medical forms. The most difficult items of functional health literacy were information-based, including nutritional facts and clinical schedules. Association between health literacy and preventive health service use was not found. Conclusions: Further study is necessary with larger samples and with considerations for their education level, age, and preventive health care use.

Objectives: We introduced the cohort studies included in the Korean Cohort Consortium (KCC), focusing on large-scale cohort studies established in Korea with a prolonged follow-up period. Moreover, we also provided projections of the follow-up and estimates of the sample size that would be necessary for big-data analyses based on pooling established cohort studies, including population-based genomic studies. Methods: We mainly focused on the characteristics of individual cohort studies from the KCC. We developed "PROFAN", a Shiny application for projecting the follow-up period to achieve a certain number of cases when pooling established cohort studies. As examples, we projected the follow-up periods for 5000 cases of gastric cancer, 2500 cases of prostate and breast cancer, and 500 cases of non-Hodgkin lymphoma. The sample sizes for sequencing-based analyses based on a 1:1 case-control study were also calculated. Results: The KCC consisted of 8 individual cohort studies, of which 3 were community-based and 5 were health screening-based cohorts. The population-based cohort studies were mainly organized by Korean government agencies and research institutes. The projected follow-up period was at least 10 years to achieve 5000 cases based on a cohort of 0.5 million participants. The mean of the minimum to maximum sample sizes for performing sequencing analyses was 5917-72 102. Conclusions: We propose an approach to establish a large-scale consortium based on the standardization and harmonization of existing cohort studies to obtain adequate statistical power with a sufficient sample size to analyze high-risk groups or rare cancer subtypes.

Background: Acute pyelonephritis (APN) is one of the most common community-acquired bacterial infections. Recent increases of antimicrobial resistance in urinary pathogens might have changed the other epidemiologic characteristics of APN. The objective of this study was to describe the current epidemiology of APN in Korea, using the entire population. Methods: From the claims database of the Health Insurance Review and Assessment Service in Korea, the patients with International Classification of Diseases, 10th Revision codes N10 (acute tubulo-interstitial nephritis) or N12 (tubulo-interstitial nephritis, neither acute nor chronic) as the primary discharge diagnosis during 2010-2014 were analyzed, with two or more claims during a 14-day period considered as a single episode. Results: The annual incidence rate of APN per 10,000 persons was 39.1 and was on the increase year to year (35.6 in 2010; 36.7 in 2011; 38.9 in 2012; 40.1 in 2013; 43.8 in 2014, P = 0.004). The increasing trend was observed in both inpatients (P = 0.014) and outpatients (P = 0.004); in both men (P = 0.042) and women (P = 0.003); and those aged under 55 years (P = 0.014) and 55 years or higher (P = 0.003). Eleven times more women were diagnosed and treated with APN than men (men vs. women, 6.5 vs. 71.3), and one of every 4.1 patients was hospitalized (inpatients vs. outpatients, 9.6 vs. 29.4). The recurrence rate was 15.8%, and the median duration from a sporadic episode (i.e., no episode in the preceding 12 months) to the first recurrence was 44 days. The recurrence probability increased with the number of previous recurrences. The average medical cost per inpatient episode was USD 1,144, which was 12.9 times higher than that per outpatient episode (USD 89). Conclusion: The epidemiology of APN in Korea has been changing with an increasing incidence rate.
