Summary Background Elevated blood pressure and glucose, serum cholesterol, and body mass index (BMI) are risk factors for cardiovascular diseases (CVDs); some of these factors also increase the risk of chronic kidney disease (CKD) and diabetes. We estimated CVD, CKD, and diabetes mortality attributable to these four cardio-metabolic risk factors for all countries and regions between 1980 and 2010. Methods We used data on risk factor exposure by country, age group, and sex from pooled analysis of population-based health surveys. Relative risks for cause-specific mortality were obtained from pooling of large prospective studies. We calculated the population attributable fractions (PAF) for each risk factor alone, and for the combination of all risk factors, accounting for multi-causality and for mediation of the effects of BMI by the other three risks. We calculated attributable deaths by multiplying the cause-specific PAFs by the number of disease-specific deaths from the Global Burden of Diseases, Injuries, and Risk Factors 2010 Study. We propagated the uncertainties of all inputs to the final estimates. Findings In 2010, high blood pressure was the leading risk factor for dying from CVDs, CKD, and diabetes in every region, causing over 40% of worldwide deaths from these diseases; high BMI and glucose were each responsible for about 15% of deaths; and cholesterol for 10%. After accounting for multi-causality, 63% (10.8 million deaths; 95% confidence interval 10.1–11.5) of deaths from these diseases were attributable to the combined effect of these four metabolic risk factors, compared with 67% (7.1 million deaths; 6.6–7.6) in 1980. The mortality burden of high BMI and glucose nearly doubled between 1980 and 2010. At the country level, age-standardised death rates attributable to these four risk factors surpassed 925 deaths per 100,000 among men in Belarus, Mongolia, and Kazakhstan, but were below 130 deaths per 100,000 for women and below 200 for men in some high-income countries like Japan, Singapore, South Korea, France, Spain, The Netherlands, Australia, and Canada. Interpretations The salient features of the cardio-metabolic epidemic at the beginning of the twenty-first century are the large role of high blood pressure and an increasing impact of obesity and diabetes. There has been a shift in the mortality burden from high-income to low- and middle-income countries.

Purpose:The first Korean national population-based cancer registry using nationwide hospital-based recording system and the regional cancer registries provided the source to obtain national cancer incidences for the period 1999～2001.M aterials and Methods: The incidence of cancer in Korea was calculated based on the Korea Central Cancer Registry database, data from additional medical record review survey, the Regional Cancer Registry databases, site-specific cancer registry databases, and cancer mortality data from the Korea National Statistical Office. Crude and age-standardized rates were calculated by sex for 18 age groups.Results: The overall crude incidence rates (CR) were 247.3 and 188.3 per 100,000 for men and women and the overall age-standardized incidence rates (ASR) were 281.2 and 160.3 per 100,000, respectively. Among men, five leading primary cancer sites were stomach (CR 58.6, ASR 65.6), lung (CR 42.1, ASR 50.9), liver (CR 41.9, ASR 44.9), colon and rectum (CR 24.2, ASR 27.3) and bladder (CR 7.7, ASR 9.2). Among women, the most common cancers were stomach (CR 30.8, ASR 25.8), breast (CR 25.7, ASR 21.7), colon and rectum (CR 19.6, ASR 16.7), uterine cervix (CR 18.4, ASR 15.5), and lung cancer (CR 15.1, ASR 12.4). In 0～14 age group, leukemia was most common for both sexes. For men, stomach cancer was most common in 15～64 age group, but lung cancer was more frequent for over 65 age group. For women, thyroid cancer in 15～34 age group, breast cancer in 35～64 age group, and stomach cancer in over 65 age group were most common for each age group. The proportions of death certificate only were 7.5% for men and 7.4% for women.Conclusion: This is the first attempt to determine the national cancer incidence and this data will be useful to plan for research and national cancer control in Korea.

R esults: O f the total of 99,025 malignancies, 55,398 (55.9% ) cases were males and 43,627 (44.1% ) were fem ales. M ore than one third of cases were from the elderly (65 years old and more). The six leading primary cancer sites in the order of their relative frequency, were stomach (24.0% ), followed by the lung (16.0% ), the liver (15.4% ), the colorectum (11.6% ), the bladder (3.2% ), and the prostate (3.0% ) among males. In females, the breast (16.8% ) was the common cancer site, followed by the stomach (15.3% ), the colorectum (10.7% ), the thyroid gland (9.5% ), the cervix uteri (9.1% ), and the lung (6.6% ).C onclusion: W ith the continued increase in cancer cases especially prostate cancer among males and thyroid cancer among females, the total number of registered cancer cases in Korea continues to rapidly increase.

The effects of embryonic stem cells (ESCs) on diabetic wound healing were investigated using an excisional skin wound model in 110 diabetes-induced rats. We transplanted a clonal population of ESCs (5 Â 10 6 ) by topical injection into full thickness skin wounds. Four study groups were used; nondiabetic rats as a control, non-insulin controlled diabetic rats not treated with ESCs, insulin controlled diabetic rats not treated with ESCs, and insulin controlled diabetic rats treated with ESCs. Five rats in each experimental group were sacrificed on days 1, 5, 10, 15, and 20 after wounding. Wounds images were acquired daily and wound sizes were calculated. We measured the mRNA levels of epidermal growth factor (EGF) and vascular endothelial growth factor (VEGF), and fibronectin levels in extracellular matrix, and assessed wound healing by assessing histological parameters of epidermal regeneration, granulation tissue thickness, and angiogenesis. In the ESC-treated group, wound sizes were significantly smaller than in the insulin controlled diabetic group not treated with ESCs on days 5 and 10 (p < 0.05), and EGF and VEGF levels were markedly higher on days 5 and 10, fibronectin levels on day 5 after injection. All histological scores in the ESC-treated group were significantly higher than those of the insulin controlled diabetic group on day 5 (p < 0.05). Our results shows that topical ESCs enhance diabetic wound healing during the early stage, and suggest that ESCs transplantation offers a novel therapeutic modality for the treatment of diabetic wounds. ß
