Cost-effectiveness of pretomanid-based regimen for highly drugresistant TB in a low-burden setting.

BACKGROUND: Recent clinical findings reported improvement in the treatment outcomes of highly resistant TB (HDR-TB) with the pretomanid (Pa) based regimen. This study aimed to evaluate the cost-effectiveness of the Pa-based regimen for HDR-TB treatment from the perspective of the healthcare sector in the United States.METHODS: A lifelong decision-analytic model was constructed to simulate potential treatment outcomes of 1) the bedaquiline-Pa-linezolid (BPaL) regimen, and 2) the bedaquiline-linezolid (B-L) based regimen in a hypothetical cohort of adult patients with HDR-TB. Primary model outputs were TB-related direct medical costs, qualityadjusted life-years (QALYs) and incremental cost per QALY gained (ICER).RESULTS: In the base-case analysis, the BPaL regimen gained 3.0054 QALYs and saved costs by USD60,433 when compared to the B-L-based regimen. In the probabilistic sensitivity analysis, the BPaL regimen gained higher QALYs at a lower cost in 80.3% of the time, and gained higher QALYs at a higher cost with ICER less than the willingness-to-pay (WTP) threshold (100,000 USD/QALY) in 19.0% of the simulations. The probability of the BPaL regimen being cost-effective was higher than the B-L-based regimen throughout the variation of WTP.CONCLUSION: BPaL therapy is likely the cost-effective option for HDR-TB treatment from the US healthcare sector perspective.

[Mortality trend of chronic respiratory diseases in China, 1990-2019].

Objective: To analyze mortality and its trend of chronic respiratory diseases (CRD) in China from 1990 to 2019. Methods: Based on the provincial results of China from the 2019 Global Burden of Disease (GBD) study, the average annual percent change (AAPC) of standardized mortality rates of different CRDs were analyzed by using Joinpoint 4.8.0.1, and the age-standardized mortality rate of CRD was calculated by using the GBD 2019 world standard population. Based on the comparative risk assessment theory of GBD, the attributable deaths due to 12 CRD risk factors were estimated, including smoking, indoor air pollution, occupational gas exposure, particulates and smog exposure, environmental particulate pollution, low temperature, passive smoking, ozone pollution, occupational exposure to silica, occupational asthma, high body mass index, high temperature and occupational exposure to asbestos. Results: From 1990 to 2019, the number of deaths and standardized mortality of chronic obstructive pulmonary disease (COPD) showed a downward trend (P<0.001). The number of COPD deaths decreased from 1 244 000 (912 000 - 1 395 000) in 1990 to 1 037 000 (889 000 - 1 266 000) in 2019. AAPC=-0.9% (95%CI: -1.5% - -0.3%), P<0.001; The standardized mortality rate decreased from 217.9/100 000 (163.3/100 000 - 242.0/100 000) in 1990 to 65.2/100 000 (55.5/100 000 - 80.1/100 000) in 2019. AAPC= -4.2% (95%CI:-5.2% - -3.2%), P<0.001. The number of deaths from asthma decreased from 40 000 (30 000 - 58 000) in 1990 to 25 000 (20 000 - 31 000) in 2019. AAPC=-2.0% (95%CI: -2.6% - -1.4%), P<0.001; The standardized mortality rate of asthma decreased from 6.4/100 000 (4.7/100 000 - 9.5/100 000) in 1990 to 1.5/100 000 (1.2/100 000 - 1.9/100 000) in 2019. AAPC=-5.1% (95%CI: -5.8% - -4.4%), P<0.001. The number of pneumoconiosis deaths decreased from 11 000 (8 000 - 14 000) in 1990 to 10 000 (8 000 - 14 000) in 2019, AAPC=-0.2%(95%CI:-0.4% - 0.1%), P=0.200; The standardized mortality rate of pneumoconiosis decreased from 1.4/100 000 (1.0/100 000 - 1.7/100 000) in 1990 to 0.5/100 000 (0.4/100 000 - 0.7/100 000) in 2019. AAPC=-3.1% (95%CI: -3.4% - -2.8%), P<0.001. The number of deaths from pulmonary interstitial diseases and pulmonary sarcoidosis increased from 3 000 (3 000 - 6 000) in 1990 to 8 000 (6 000 - 10 000) in 2019, AAPC=3.5% (95%CI: 2.7% - 4.2%), P<0.001; The corresponding standardized mortality rate changed little from 1990 to 2019, and AAPC was not statistically significant.The age-standardized mortality rates of different CRDs were higher in men than those in women. In 1990 and 2019, the mortality rates of COPD, asthma, pneumoconiosis and interstitial pulmonary disease and pulmonary sarcoidosis increased with age. In 2019, the population attributable fractions (PAFs) for smoking, environmental particulate pollution, occupational gas exposure, particulate and smog exposure, low temperature exposure and passive smoking were 71.1% (68.0% - 74.3%), 24.7% (20.1% - 30.0%), 19.3% (13.0% - 25.4%), 15.7% (13.6% - 18.3%) and 8.8% (4.5% - 13.1%) respectively in men, and the PAFs for environmental particulate pollution, smoking, low temperature exposure, occupational gas exposure, particulate and smog exposure, and passive smoking were 24.1% (19.6% - 29.3%), 21.9% (18.7% - 25.2%), 16.4% (14.0% - 19.2%), 15.6% (10.2% - 21.1%) and 14.7% (7.9% - 21.3%) respectively in women. Conclusions: During 1990-2019, the overall death level of CRD decreased significantly in China, but it is still at high level in the world. Active prevention and control measures should be taken to reduce the death level caused by CRD.

Emergence of two-level systems in glass formers: a kinetic Monte Carlo study.

Using a distinguishable-particle lattice model based on void-induced dynamics, we successfully reproduce the well-known linear relation between heat capacity and temperature at very low temperatures. The heat capacity is dominated by two-level systems formed due to the strong localization of voids to two neighboring sites, and can be exactly calculated in the limit of ultrastable glasses. Similar but weaker localization at higher temperatures accounts for glass transition. The result supports the conventional two-level tunneling picture by revealing how two-level systems emerge from random particle interactions, which also cause glass transition. Our approach provides a unified framework for relating microscopic dynamics of glasses at room and cryogenic temperatures.

[Disease burden of breast cancer in women in China, 1990-2017].

Objective: To analyze the trend of the incidence, mortality and disease burden of breast cancer in women in China during 1990-2017. Methods: Based on the estimation of data in China from the Global Burden of Disease 2017 (GBD2017), the incidence,mortality, disability- adjusted life years (DALY), years of life lost (YLL), and years lived with disability (YLD) on breast cancer for women in China during 1990-2017 were standardized by the world standard population used for GBD2017. The GBD study applied the attributable burden formula to estimate the attributable deaths by five risk factors of breast cancer, including alcohol use, high body mass index (BMI), high fasting plasma glucose, low physical activity and tobacco smoking. The incidence, mortality, attributable deaths and the disease burden due to breast cancer in women in China were analyzed. Results: In 2017, a total of 357.6 thousand female breast cancer cases, including 84.8 thousand deaths, were reported in China, with the age-standardized incidence rate of 35.62/100 000, which increased by 286.18%, 114.14% and 88.77% respectively compared with 1990. The age-standardized mortality rate decreased from 8.57/100 000 in 1990 to 7.84 /100 000 in 2007, then increased to 8.71 /100 000 in 2015, and then decreased to 8.47/100 000 in 2017. The mortality of breast cancer increased with age in 1990 and 2017. From 1990 to 2017, the trend of standardized DALY rate and standardized YLL rate were the same as that of standardized mortality, while the standardized YLD rate and the proportion of YLD in DALY increased year by year. In 2017, the standardized DALY rate, standardized YLL rate and standardized YLD rate of breast cancer were 253.00/100 000, 228.96/100 000, and 24.05/100 000, respectively. Compared with 1990, the change rates were -6.88% and -11.73% and 95.85% respectively. The proportion of breast cancer deaths attributable to high BMI increased significantly by 165.76%, from 5.49% in 1990 to 14.59% in 2017. The proportion of breast cancer deaths attributable to alcohol use and high fasting blood glucose increased; and the proportion of breast cancer deaths attributed to low physical activity and smoking remained stable. In 2017, the three provinces with the highest age-standardized mortality rate of female breast cancer were Hongkong (9.93/100 000), Guangxi (9.52/100 000) and Liaoning (9.49/100 000). Compared with 1990, the age-standardized mortality of 19 provinces decreased, and Beijing (-27.17%), Macao (-26.06%) and Jilin (-23.89%) had the fastest decrease. The two provinces with the highest growth rates were Hebei (28.85%) and Henan (24.34%). Conclusions: The disease burden of female breast cancer in China increased during 1990-2017. Therefore it is necessary to strengthen the prevention and treatment of breast cancer.

Quality Metrics in Hand Surgery: A Systematic Review.

PURPOSE: The enactment of the Patient Protection and Affordable Care Act in 2010 placed an emphasis on measuring the quality of care. However, the issue of how best to measure quality remains in question. Although some surgical specialties frequently rely on quality measures such as the mortality rate, measuring quality in hand surgery necessitates the use of metrics beyond this traditional scope. A review was performed of the potential quality metrics used in the hand surgery literature published after the Affordable Care Act was enacted, to identify current trends in quality measurement and guide efforts to improve the quality of care in hand surgery. METHODS: We searched the PubMed and EMBASE databases to identify original research articles within hand surgery to assess how care is being measured. Data extracted from the articles included study characteristics, quality metrics, and the domain(s) of quality. RESULTS: A total of 7,308 articles were identified, and 63 prospective and retrospective articles were included in the analysis. The most common quality measure reported in the hand surgery literature was an outcome measure (100%) and the least common was a structure measure (30.2%). The most common metrics were pain (44.4%) and patient-reported measures (41.3%). Effectiveness (42.9%) was the most frequently assessed domain of quality, whereas efficiency (3.2%) was the least studied. CONCLUSIONS: We identified quality measures used in contemporary hand surgery literature and found a substantial variation in the representation of quality metrics. Structure and process measures can be leveraged to provide a more holistic assessment of the quality of care in hand surgery. CLINICAL RELEVANCE: Although outcome measurements are critical to understanding effectiveness, structure and process measures should be considered and reported as necessary, because these metrics may influence treatment outcomes and the development of quality measures.

Insurance Reimbursement in Plastic Surgery.

SUMMARY: The ambiguity of medical finances, both to the patient and to the provider, has direct effects on the quality of care that is delivered to the patient. To encourage transparency in health care, physician reimbursement is a process that must be understood to ensure patient satisfaction, a physician's willingness to deliver care, and the success of health care facilities. Furthermore, physicians should be aware of the effects that legislative action, such as the Patient Protection and Affordable Care Act, has on their income. As a field that encompasses both cosmetic and reconstructive surgery, plastic surgeons must know this process intimately to ensure efficient services and appropriate reimbursement. In particular, plastic surgeons should be familiar with how the Affordable Care Act affects their income, practice, and the patient's access to care. As Medicare and Medicaid continue to increase health care access for many Americans, specialists such as plastic surgeons will need to reinforce the value of the specialty in the continuum of care. As the health care industry moves away from a fee-for-service system to one of value-based care, plastic surgeons need to be at the forefront of this transition to ensure that they are delivering quality care, and receiving appropriate reimbursement. The authors have provided data from the University of Michigan to demonstrate the reimbursement patterns seen in plastic surgery. This Special Topic article provides insight into the reimbursement process in the era of the Affordable Care Act and the various challenges that may be encountered within this field.

[Clinical significance and cost-benefit analysis of serum calcitonin assay in diagnosis and treatment of medullary thyroid carcinoma].

Objective: To study the clinical significance of serum calcitonin in the diagnosis and treatment of medullary thyroid carcinoma and to analyze its cost-benefit. Methods: One hundred and forty one patients with medullary thyroid carcinoma who undertook calcitonin test and frozen pathological examination were enrolled in this study from Oct 2012 to Mar 2018. Using the method of χ(2) test, the positive rate of calcitonin test and frozen pathological examination in diagnosis of medullary thyroid carcinoma(MTC) were compared. Firstly, we compared the correct checkout cost of calcitonin test and that of frozen pathological examination (total number of patients×cost of examination/the correctly detected number of patients) . Secondly, we calculated whether calcitonin test help patients save money(average cost of treatment in hospital for MTC×number of patients who were evaluated to be candidate for surgery-cost of calcitonin test×total number of patients)/total number of patients. Results: 139 patients were positive in calcitonin test among 141 patients, and the positive rate was 98.58%. 91 patients were positive in frozen pathological examination, and the positive rate was 64.54% (χ(2)=97.821, P<0.000 1) . Cost-benefit analysis showed that the correct checkout cost of calcitonin test and frozen pathological examination were 71.01 yuan and 426.10 yuan, also,1 371 938.64 yuan could be saved totally and 9 730.06 yuan could be saved per patient because of calcitonin test. Conclusion: Serum calcitonin test had a significant effect on the diagnosis and treatment of medullary thyroid carcinoma and was economical and practical.

[Survey on burden of disease attributable to low fruit intake among Chinese people aged 15 years old and above between 1990 and 2013].

Objective: To analyze the burden of disease attributable to low fruit intake among Chinese population aged ≥15 years old between 1990 and 2013. Methods: We used data from the 2013 Global Burden of Disease Burden of Disease Study to study the situation in China. The population attributable fraction was calculated to estimate and compare the death and disability-adjusted life years (DALY) attributed to low fruit intake between 1990 and 2013 in China (excluded Taiwan, China). An average world population age structure of the period 2000-2025 was adopted to calculate age-standardized rates. Results: Deaths attributable to low fruit intake accounted for 11.02% of all death in 2013, which were higher than it in 1990 (10.38%). In 2013, the number of deaths attributed to low fruit intake in China increased to 1 046 500 from 793 800 in 1990. From 1990-2013, the age-standardized death rate attributable to low fruit intake decreased from 113.04/100 000 to 79.80/100 000. DALYs caused by low fruit intake increased from 18.346 5 million in 1990 to 21.296 7 million in 2013. Compared with 1990, the age-standardized DALY rate attributed to low fruit intake decreased by 34.67%. In 2013, the top three provinces with the highest burden of disease attributed to low fruits intake were Tibet, Guizhou and Xinjiang provinces, with standardized DALY rate at 2 612.53/100 000, 2 281.85/100 000 and 2 198.22/100 000, respectively. Compared with the results in 1990, the standardized DALY attributed to low fruits intake decreased, especially in Tianjin, where decreased by 63.61%; followed by Aomen, Zhejiang, Shanghai and Beijing, where decreased by 59.74%, 59.53%, 56.64% and 53.88%, respectively. Conclusion: Compared with the situation in 1990, the burden of disease attributable to low fruit intake decreased in 2013, but the situation is still serious, especially in Tibet, Guizhou and Xinjiang provinces, where the burden decreased comparatively slowly.

[Effects of insufficient physical activity on motality and life expectancy in adult aged 25 and above among Chinese population].

Objective: To analyze the attribution of mortality and impact on life expectancy caused by insufficient physical activity in different gender and areas in adults aged ≥25 years among Chinese people. Methods: Data from the programs related to Chinese death surveillence, risk factors of chronic survey, health outcomes of physical activity as well as relative risk (RR) on Global Burden of Disease (GBD) study were used. Population attributable fraction (PAF) of different health outcomes attributable to deaths that caused physical activity and the influence of life expectancy in adults aged ≥25 years in Chinese people were calculated. Results: The overall PAF for all cause of death due to physical activity in adults aged ≥25 years was 4.24%, with 4.86% in females and 3.82% in males. The health outcomes of inadequate physical activity would include breast cancer, colorectal cancer, ischemic heart disease, ischemic stroke and diabetes with relative PAFs as 9.04%, 13.96%, 14.96%, 17.80% and 16.92%, respectively. The attribution of death on Physical activity was 388 954. The most attributed death was ischemic heart disease, followed by ischemic stroke. With the elimination of physical inactivity, the total life expectancy was expected to lose by 0.43 years, with 0.47 years in women, and 0.39 years in men. Conclusion: The increase of physical activity may benefit on health condition so to reduce the burden of chronic diseases and increase the life expectancy.

[Disease burden attributable to household air pollution in 1990 and 2013 in China].

Objective: To assess the disease burden attributable to household air pollution in 1990 and 2013 in China. Methods: Based on data from the Global Burden of Disease Study 2013 in China (GBD 2013), we used population attributable fractions (PAF) to analyze the burden of different diseases attributable to solid-fuel household pollution in 2013 in China(not inclnding HongKang, Macao, Taiwan). We compared PAF, mortality, and disability-adjusted life years (DALY) for diseases attributable to solid-fuel household pollution in 31 provinces in mainland China in 1990 and 2013, and stratified the burden by age group. The estimated world average population during 2000- 2025 was used to calculate age-standardized mortality and DALY rates. Results: In 2013, 14.9% of lower respiratory infections in children <5, 32.5% of chronic obstructive pulmonary disease (COPD), 12.0% of ischemic stroke, 14.2% of hemorrhagic stroke, 10.9% of ischemic heart disease, and 13.7% of lung cancer were attributable to solid-fuel household pollution. In addition, 807 000 deaths were attributable to solid-fuel household pollution, including 296 000 from COPD, 169 000 from hemorrhagic stroke, 152 000 from ischemic heart disease, 88 000 from ischemic stroke, 75 000 from lung cancer, and 28 000 from lower respiratory infections in children <5. The age-standardized mortality rate from solid-fuel household pollution decreased by 59.3% from 158.8/100 000 in 1990 to 64.6/100 000 in 2013. The age-standardized mortality rate from solid-fuel household pollution decreased in all 31 provinces, with the highest decline observed in Shanghai (96.3%), and lowest in Xinjiang (39.9%). In 2013, the age-standardized DALY rate from solid-fuel household pollution was highest in Guizhou (2 233.0/100 000) and lowest in Shanghai (27.0/100 000). The DALY rate was the highest for the >70 age group (7 006.0/100 000). Compared with 1990, the 2013 mortality rate and DALY rate from solid-fuel household pollution decreased in all age groups, with the highest decline observed in the <5 age group (91.9% and 91.8% , respectively). Conclusion: Although the disease burden attributable to household air pollution decreased notably between 1990 and 2013, household pollution caused a high number of deaths and DALY loss in certain western provinces.

Potential clinical and economic outcomes of active beta-D-glucan surveillance with preemptive therapy for invasive candidiasis at intensive care units: a decision model analysis.

Early initiation of antifungal treatment for invasive candidiasis is associated with change in mortality. Beta-D-glucan (BDG) is a fungal cell wall component and a serum diagnostic biomarker of fungal infection. Clinical findings suggested an association between reduced invasive candidiasis incidence in intensive care units (ICUs) and BDG-guided preemptive antifungal therapy. We evaluated the potential cost-effectiveness of active BDG surveillance with preemptive antifungal therapy in patients admitted to adult ICUs from the perspective of Hong Kong healthcare providers. A Markov model was designed to simulate the outcomes of active BDG surveillance with preemptive therapy (surveillance group) and no surveillance (standard care group). Candidiasis-associated outcome measures included mortality rate, quality-adjusted life year (QALY) loss, and direct medical cost. Model inputs were derived from the literature. Sensitivity analyses were conducted to evaluate the robustness of model results. In base-case analysis, the surveillance group was more costly (1387 USD versus 664 USD) (1 USD = 7.8 HKD), with lower candidiasis-associated mortality rate (0.653 versus 1.426 per 100 ICU admissions) and QALY loss (0.116 versus 0.254) than the standard care group. The incremental cost per QALY saved by the surveillance group was 5239 USD/QALY. One-way sensitivity analyses found base-case results to be robust to variations of all model inputs. In probabilistic sensitivity analysis, the surveillance group was cost-effective in 50 % and 100 % of 10,000 Monte Carlo simulations at willingness-to-pay (WTP) thresholds of 7200 USD/QALY and ≥27,800 USD/QALY, respectively. Active BDG surveillance with preemptive therapy appears to be highly cost-effective to reduce the candidiasis-associated mortality rate and save QALYs in the ICU setting.

Expedited Holonomic Quantum Computation via Net Zero-Energy-Cost Control in Decoherence-Free Subspace.

Holonomic quantum computation (HQC) may not show its full potential in quantum speedup due to the prerequisite of a long coherent runtime imposed by the adiabatic condition. Here we show that the conventional HQC can be dramatically accelerated by using external control fields, of which the effectiveness is exclusively determined by the integral of the control fields in the time domain. This control scheme can be realized with net zero energy cost and it is fault-tolerant against fluctuation and noise, significantly relaxing the experimental constraints. We demonstrate how to realize the scheme via decoherence-free subspaces. In this way we unify quantum robustness merits of this fault-tolerant control scheme, the conventional HQC and decoherence-free subspace, and propose an expedited holonomic quantum computation protocol.

[Burden of disease attributable to high- sodium diets in China, 2013].

Objective: To examine the burden of disease(BOD)attributable to high-sodium diets in China in 2013. Methods: Data were extracted from the 2013 Global Burden of Disease Study for China to examine the BOD attributable to high-sodium diets in 2013, gender, and disease composition. Measurements for attributable BOD were population attributable fraction(PAF), deaths, standardized mortality and disability-adjusted life years(DALY)(not including Taiwan, China). An average world population age-structure for the period 2000-2025 was adopted to calculate age-standardized rates. Results: In 2013, deaths attributable to high-sodium diets accounted for 12.6% of all deaths and 14.5% of chronic disease deaths. Overall, 7.8% of deaths because of neoplasms, 25.2% of cardiovascular disease deaths, and 22.9% of chronic kidney disease deaths were attributable to high-sodium diets. A total of 1 176 553 deaths were attributable to high-sodium diets and the standardized mortality was 91.5/100 000, which was higher in men than in women(121.7/100 000 and 63.0/100 000, respectively). Overall, 22.759 million DALYs were attributable to high-sodium diets. The DALY standardized rate was 1 588.0/100 000, which was higher in men than in women(2 189.7/100 000 and 993.2/100 000, respectively). When compared by province, PAF in Xinjiang(25.0%), Qinghai(23.7%), Shanxi(23.2%), Tibet(22.1%)and Shandong(20.5%)was higher than other provinces. The standardized mortality in Xinjiang(239.4/100 000), Qinghai(238.9/100 000), Tibet(221.7/100 000), Shanxi(166.2/100 000)and Hebei(149.9/100 000)were higher than other provinces. The DALY standardized rate attributable to high-sodium diets was highest in Xinjiang(4 430.8/100 000), Qinghai(4 422.5/100 000), Tibet(4 021.4/100 000), Shanxi(2 816.6/100 000), and Hebei(2 624.9/100 000). Conclusion: The BOD attributable to high-sodium diets is a serious issue in China, particularly in men and in the northern provinces. Effective measures should be taken in northern provinces to reduce sodium intake.

[Burden of disease attributed to high total cholesterol in 2013 in China].

Objective: To analyze the burden of disease attributed to high total cholesterol(TC)in 2013 in China. Methods: We used data from the 2013 Global Burden of Disease Study. The population attributable fraction was calculated to estimate the deaths and disability-adjusted life years(DALY)attributed to high TC. Disease burden was compared by age, gender, diseases and province(not including Taiwan, China). An average world population age structure for the period 2000- 2025 was adopted to calculate age-standardized rates. Results: In 2013, high TC caused 298 952 deaths in China, accounting for 3.3% of total deaths, and caused 6 332 thousand DALYs. DALYs attributed to high TC were highest among the 50-69 years age group(3 165 thousand person years), accounting for 50.0% of the total attributed DALYs. The DALY rate in the ≥70 years age group was 2 053.3/100 000, which was 10.3 times that of 15-49 age group(198.6/100 000). DALYs among men were 4 431 thousand person years, which was 2.3 times higher than in women(1 900 thousand person years), and the age-standardized DALY rate among men was 590.6/100 000, which was 2.3 times higher than in women(257.1/100 000). DALYs attributed to high TC were mainly caused by ischemic heart disease(IHD; 5 572 thousand person years), accounting for 88.0% of the total attributed DALYs. Deaths and DALYs attributed to high TC were highest in Shandong(31 002 and 628 thousand person years for deaths and DALYs, respectively), Henan(27 398 deaths and 587 thousand person years, respectively), Hebei(25 744 deaths and 589 thousand person years, respectively), accounting for 28.1% of total attributed deaths and 28.5% of total attributed DALYs. The number of deaths and DALY were lowest in Macao(75 deaths and 1 thousand person years, respectively)and Tibet(385 deaths and 10 thousand person years, respectively). The age standardized DALY rates were highest in Beijing(794.8/100 000), Hebei(732.7/100 000), and Jilin(709.1/100 000), and lowest in Shanghai(151.4/100 000), Zhejiang(168.1/100 000), and Hong Kong(182.0/100 000). Conclusion: The burden of disease attributed to high TC in 2013 in China was mainly the result of the IHD it causes, with greater influence among males and those aged ≥50 years, and variation among provinces.

[Burden of disease attributable to high fasting plasma glucose in 1990 and 2013 in China].

Objective: To analyze the burden of disease attributed to high fasting plasma glucose(FPG)in China in 1990 and 2013. Methods: The analysis used data obtained from the 2013 Global Burden of Diseases Study and examined deaths, death rate, disability-adjusted life years(DALY), years lived with disability(YLD)and years of life lost(YLL)attributed to high FPG in 1990 and 2013 in China(not including Taiwan, China). An average world population age-structure for the period 2000- 2025 was adopted to calculate age-standardized rates. Results: In 2013, the number of deaths attributed to high FPG in China increased to 621.9 thousand from 320.3 thousand in 1990. From 1990- 2013, the age-standardized death rate attributable to high FPG increased from 45.69/100 000 to 48.64/100 000. DALYs caused by high FPG increased to 20.389 1 million in 2013 from 10.648 3 million in 1990. In 2013, high FPG caused 8.751 5 million YLD and 11.637 6 million YLL, and the percentage of YLL in DALY decreased to 57.1% in 2013 from 68.7% in 1990. Compared with 1990, the age-standardized DALY rate attributed to high FPG increased by 10.81%. In 2013, the top three provinces with the highest burden of disease attributed to high FPG were Xinjiang, Jilin and Liaoning provinces, with standardized death rates of 83.38, 74.01 and 68.64/100 000, respectively, and the standardized DALY rate was 2 217.96, 2 001.84 and 1 837.79/100 000 in the three provinces, respectively. Conclusion: Compared with 1990, the burden of disease attributed to high FPG in 2013 increased substantially in China, in particular the burden of attributed YLD. However, the burden of YLL attributed to high FPG has decreased modestly. The burden of disease caused by high FPG shows variation among different provinces in China.

[Disease burden of lung cancer in the Chinese population, in 1990 and 2013].

OBJECTIVE: To analyze the disease burden of lung cancer in the Chinese population, in 1990 and 2013. METHODS: Indicators including mortality rate, years of life lost due to premature mortality (YLL), years lived with disability (YLD), and disability-adjusted of life years (DALY) on lung cancer, were from the results of Global Burden of Disease (GBD) 2013 and were used to describe the burden of disease caused by lung cancer in the Chinese population. Data described the disease burden of lung cancer in China by calculating the changing rates on corresponding parameters in 1990 and 2013. RESULTS: In China, in 1990 and 2013, the standardized mortality rate of lung cancer increased from 36.04/100 000 to 40.41/100 000 (increased by 12.13%), the standardized YLL rate decreased from 805.07/100 000 to 781.09/100 000 (decreased by 2.98%), the standardized YLD rate increased from 8.57/100 000 to 11.13/100 000 (increased by 29.87%) and the standardized DALY rate decreased from 813.64/100 000 to 792.22/100 000 (decreased by 2.63%). Compared with data in 1990,parameters as the number of deaths, YLL, YLD and DALY of lung cancer all increased, especially in males. Mortality and the DALY rate of lung cancer increased with age in both genders. Mortality and DALY rate were higher in males than those in females in all the age groups. Geographically, standard mortality rate and standard DALY rate in northeast region, north region, southwest region (Sichuan and Chongqing) and part of the east and central regions appeared significantly higher than those in other regions but lower in western region than those in other regions, in 2013. CONCLUSIONS: Burden of disease caused by lung cancer remained serious in China. Provincially,the burden of disease caused by lung cancer appeared different. It is important to strengthen the prevention and control programs that related to lung cancer.

Financial burden on the families of patients with hepatitis B virus-related liver diseases and the role of public health insurance in Yunnan province of China.

OBJECTIVE: To investigate the financial burden of patients who had various stages of hepatitis B virus-related diseases and the level of alleviation from financial burden by health insurance schemes in Yunnan province of China. STUDY DESIGN: A cross-sectional survey. METHODS: Patients' information was consecutively recorded at the First Affiliated Hospital of Kunming Medical University, from December 2012 to June 2013. Consecutive cases of hepatitis B virus (HBV) (520), compensated cirrhosis (91), decompensated cirrhosis (198) and hepatocellular carcinoma (HCC) (131) were recruited from the outpatient and inpatient departments. The total direct costs, hospital charge, outpatient costs, hospitalization fees being reimbursed and household catastrophic health expenditure were estimated for each disease group. RESULTS: The average annual direct costs for each disease group were 19,496 RMB for HBV, 28,466 RMB in compensated cirrhosis, 46,061 RMB for decompensated cirrhosis, and 33,044 RMB for HCC patients. Catastrophic health expenditure occurred in all four groups. Health insurance reimbursement released the financial burden incurred by medical expenses of patients under a high level of household economic status. Public health insurance schemes helped the patients to various extents. CONCLUSIONS: Among these patient groups, direct costs represent a significant economic burden. Health expenditure and financing systems must be considered to prevent the increase of household catastrophe, particularly among the poor.
