RESUMO
BACKGROUND: The intricate relationship between hypertension and chronic kidney disease (CKD) presents a global challenge for prevention of hypertension-related CKD. This study's objective is to analyze age, gender, regional disparities, and evolving trends in the disease burden of hypertension-related CKD. We aim to estimate changing spatial and temporal trends in incidence and mortality rates, considering the socio-demographic index (SDI), to inform health strategies effectively. METHOD: Age-standardized incidence rates (ASIR) and death rates (ASDR) were collected from the GBD 2019. Trend analysis was conducted by Joinpoint regression of ASRs from 1990 to 2019. Spatial autocorrelation analysis was performed to obtain spatial patterns. The association between SDI and burden of CKD due to hypertension was estimated using a Pearson correlation analysis. RESULTS: The global ASIR and ASDR due to hypertension-related CKD were 19.45 (95% CI, 17.85 to 21.09) and 5.88 (95% CI, 4.95 to 6.82) per 100 K population in 2019, representing increases of 17.89% and 13.29% compared to 1990, respectively. The elderly population and males were found the highest ASIR and ASDR. The high SDI region had the highest ASIRs, while low SDI regions experienced the highest ASDRs. Joinpoint regression found both global ASIR and ASDR showed increasing trends, with the highest increases observed in middle- and high-SDI regions, respectively. The SDI exhibited a positive association with ASIRs but displayed an inverse V-shaped correlation with the average annual percentage change (AAPC) of ASIRs. Spatial autocorrelation analysis revel significant positive spatial autocorrelation for the AAPC of ASDRs and ASIRs, from 1990 to 2019. CONCLUSIONS: Results met the objectives, and demonstrated a rising global burden of hypertension-related CKD. Factors such as aging, gender, and regional variations should be considered when designing control measures and developing healthcare systems to effectively address the burden of this complex condition.

Purpose: Tiotropium/olodaterol (TIO/OLO) fixed-dose combination (FDC) can improve lung function and quality of life for patients with chronic obstructive pulmonary disease (COPD), and is not inferior to other LAMA/LABAs. The aim of this study was to assess the cost-effectiveness of TIO/OLO FDC in patients with moderate to very severe COPD in China. Methods: A Markov model was developed to estimate the cost-effectiveness of TIO/OLO FDC versus TIO in the treatment of COPD from Chinese health system perspective. Four health states were based on 2021 Global Initiative for Chronic Obstructive Lung Disease (GOLD 2021), which included moderate (GOLD II, 50% ≤ FEV1 ≤ 80% of predicted), severe (GOLD III, 30% ≤ FEV1 ≤ 50% of predicted) and very severe (GOLD IV, FEV1 > 30% of predicted) COPD and death. The model simulated in cycles yearly. The indicators of total costs, number of COPD exacerbations, life years (LYs) and quality-adjusted life-years (QALYs) were used as the model output. Costs and outcomes were discounted at a 5% annual rate. A cost-effectiveness analysis was conducted over a 10-year time horizon. The threshold of incremental total cost per unit effectiveness gained (ICER) was 1.5 times of GDP per capita. Uncertainty was assessed by one-way and probabilistic sensitivity analysis. Results: TIO/OLO was 0.007 QALYs more than TIO but 0.012 LYs lower, which increased the total cost by $2268.17 per patient, but the total exacerbations number was less. Incremental cost effectiveness analysis had shown that the ICER exceeded the willingness to pay threshold. Results were robust under most parameter variation, except the parameters of total drug cost of TIO/OLO FDC in univariate sensitivity analyses. Conclusion: Although TIO/OLO FDC could reduce the exacerbation risk, it was not cost-effective, and needed to be repriced.

BACKGROUND: A universal set of disability weights(DWs) is mainly based on the survey of North America, Australia and Europe, whereas the participants in Asia was limited. The debate hasn't yet settled whether a universal DW is desirable or useful.The focus of the debate is its representativenes-s.After all, the DWs come from people's subjective evaluation of pain, and they may vary according to cultural background.The differences of the DWs could have implications for the magnitude or ranking of disease burdens.The DWs of Anhui Province has not been completely presented.This paper aims to obtain the DWs suitable for the general population of Anhui Province of China, and attempts to explore the differences between different DWs by comparing the DWs with the similar-cultural background and the DWs with cross-cultural background. METHODS: A web-based survey was conducted to estimate the DWs for 206 health states of Anhui province in 2020. Paired comparison (PC) data were analyzed and anchored by probit regression and fitting loess model. We compared the DWs in Anhui with other provinces in China and those in Global burden of disease (GBD) and Japan. RESULTS: Compared with Anhui province, the proportion of health states which showed 2 times or more differences ranged from 1.94% (Henan) to 11.17% (Sichuan) in China and domestic provinces. It was 19.88% in Japan and 21.51% in GBD 2013 respectively. In Asian countries or regions, most of the health states with top 15 DWs belonged to the category of mental, behavioral, and substance use disorders. But in GBD, most were infectious diseases and cancer. The differences of DWs in neighboring provinces were smaller than other geographically distant provinces or countries. CONCLUSION: PC responses were largely consistent across very distinct settings,but the exceptions do need to be faced squarely.The differences of DWs among similar-cultural regions were smaller than cross-cultural regions. There is an urgent need for relevant gold standards.

BACKGROUND: Prenatal fine particulate matter (PM2.5) exposure is related to various neonatal diseases (ND). However, data and studies assessing the neonatal disease burden caused by PM2.5 at the global level are limited, especially comparing countries with various socioeconomic development levels. We, therefore, assessed three-decades spatiotemporal changes in neonatal disease burden from 1990 at a national level, combined with the socio-demographic index (SDI). METHODS: We extracted statistics from the Global Burden of Disease Study database for this retrospective study, and analyzed differences in the age-standardized mortality rate (ASMR) of ND and five sub-causes related to PM2.5 by gender, nationality, and SDI. To describe the trend of ASMR, the Joinpoint model was adopted to predict the annual percentage change (APC) and the average annual percentage changes (AAPCs). We executed the Gaussian process regression model to predict the relevance between SDI and ASMR. RESULTS: The ND burden associated with PM2.5 kept rising since 1990, especially in low-middle SDI regions, South Asia, and Sub-Saharan Africa, and the sex ratio of ASMR was >1 at the global level and all five SDI regions. The leading cause of death was neonatal preterm birth. The global ASMR level of ND was 2.09 per 100,000 population in 2019 and AAPCs was 0.91 (98 % CI: 0.28, 1.55) meanwhile AAPCs decreased with rising SDI levels. The decreasing trend of ASMR in ND was detected in regions with higher SDI, such as North America, Europe, and Australasia. CONCLUSIONS: In the past three decades, the global burden of ND related to PM2.5 has ascended considerably in lower SDI regions hence PM2.5 is still considered a notable environmental hazard factor for newborn diseases.

Background: Fixed dose dual bronchodilators such as long-acting muscarinic antagonists (LAMAs) plus long-acting ß2-agonists (LABAs) are a new and important inhaled preparation for COPD treatment in China. Among these, umeclidinium/vilanterol (UMEC/VIL) is increasingly being used in China, especially among the elderly. Purpose: This study aimed to assess the cost-effectiveness of maintenance treatment with UMEC/VIL compared with salmeterol/fluticasone (FSC) as one of the main therapeutic drugs for moderate to very severe COPD in China. Methods: A Markov model was developed to estimate the costs and outcomes from a societal perspective in a 10-year time horizon. Patients with moderate-to-very severe COPD were treated with UMEC/VIL (62.5/25µg) or FSC (50/500ug). Data concerning clinical efficacy, costs, utilities, transition probability, exacerbation rate, and mortality were obtained from the published literature and official government datasets. The costs were presented in US dollars based on 2021 prices. The indicators of total costs, life years (LYs), quality-adjusted life-years (QALYs), and mortality were used as the model output. Costs and outcomes were discounted at a 5% annual rate. Incremental cost-effectiveness ratios were calculated considering the threshold recommended by WHO. One-way and probabilistic sensitivity analyses were conducted to assess the stability of results. Results: Compared with FSC, treatment with UMEC/VIL could save $1947.18, with a gain of 0.12 life-years and 0.05 QALYs. Further, 28.0% patients treated with UMEC/VIL and 29.2% patients treated with FSC were predicted to die after 10 years. Incremental cost effectiveness analysis showed that UMEC/VIL was dominant to FSC. Sensitivity analyses confirmed that the results were robust. Conclusion: UMEC/VIL is a cost-effective treatment option compared with FSC among patients with moderate-to-very severe COPD.

Inclusive green growth (IGG), as a new way to attain sustainable development, aims to achieve comprehensive and coordinated economic, social, and environmental development. How to define IGG and explore its driving factors is key to realizing IGG. This study takes China as an example, using panel data from 30 provinces in Mainland China from 2009 to 2018 for research. The epsilon-based measure (EBM) model and Global Malmquist-Luenberger (GML) index are used to evaluate China's IGG, and a spatial panel regression model of the impact of urban land resource misallocation on IGG is established. The research found that (1) China's IGG level from 2009 to 2018 displayed an upward trend, and combined with exploratory spatial data analysis (ESDA), it was found that IGG has an obvious spatial correlation; (2) the regression model shows that the misallocation of land resources hinders the improvement of IGG in China; and (3) the decomposition of spatial spillover effects demonstrates that the misallocation of land resources has negative externalities, which will also have adverse effects on neighboring areas.

The transformation of China's economy from extensive growth to high-quality development is essentially an increase in green total factor productivity (GTFP). China currently has a range of environmental regulation tools, and the question of whether environmental regulation can promote improvement in China's GTFP requires theoretical and empirical analysis. This article first divides environmental regulation into three types: administrative, market-based and information-based. It then builds an empirical model of the effect of environmental regulation on GTFP. Slacks based measure-data envelope analysis (SBM-DEA) and the Malmquist index are used to measure the GTFP of 30 provinces in China from 2005 to 2018, and a measurement model of the impact of environmental regulation on GTFP is established. The results show that: (1) there are significant differences in GTFP in eastern, central and western China; (2) there is a non-linear relationship between environmental regulations and GTFP.

OBJECTIVE: To investigate the temporal trends in mortality and disease burden of injuries in Anhui province from 2008 to 2017, so as to provide reference for injury control and prevention. METHODS: Data of mortality were collected from 9 national surveillance points in Anhui province during 2008-2017 in the Information System for Death Cause Register and Management. The surveillance data were analyzed by using crude mortality, standardized mortality rate (SMR), potential year of life lost (PYLL), PYLL rate (PYLLR), and average of year life lost (AYLL). RESULTS: There were a total of 44855 people died from injury, accounted for 9.44% of the all-cause mortality, ranked as the fifth leading cause of deaths in the whole population, and denoted the first leading cause of deaths in the 0-44 year's group. The leading causes of injury deaths were road traffic accidents, suicide, accidental falls, drowning, and poisoning. Road traffic accidents was the primary cause of injury deaths among the male population, while suicide was the dominate cause of injury deaths among the female population. Drowning, traffic accidents, and suicide accounted for the most injury deaths among the population aged 0-14 years, 15-64 years, and above 60 years, respectively. The road traffic accidents accounted for the largest proportion of injury PYLL and PYLLR, and drowning caused the highest AYLL among injury deaths. CONCLUSION: In Anhui province, road traffic accidents, suicide, accidental falls, drowning, and poisoning were the top five causes of injury deaths that harm the health of local residents; corresponding injury prevention strategies should be formulated.

BACKGROUND: The associations of occupational activity (OA), commuting, leisure-time physical activity (LTPA), and sitting with overweight/obesity in working adults are controversial. This study explored these factors with the risk of overall and abdominal overweight/obesity in a Chinese working population and whether these associations differ by gender. METHODS: A cross-sectional study was conducted. Data analysis was done among 6739 employed participants. Multivariate logistic regression was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for the studied associations. RESULTS: For male employees, those with heavy OA had a lower overall (OR 0.76; 95% CI, 0.62-0.93) and abdominal (OR 0.76; 95% CI, 0.62-0.93) overweight/obesity risk than those with light OA. Those with LTPA ≥150 min/week had a lower risk of overall (OR 0.73; 95% CI, 0.56-0.96) and abdominal (OR 0.70; 95% CI, 0.53-0.91) overweight/obesity than those with LTPA <150 min/week. Men with leisure-sitting time <2.5 h/day had a significantly lower risk of abdominal overweight/obesity than those sitting ≥4 h/day (OR 0.80; 95% CI, 0.65-0.99). And men who cycled to/from work had a lower risk of overall (OR 0.69; 95% CI, 0.53-0.90) and abdominal overweight/obesity (OR 0.71; 95% CI, 0.54-0.92) than passive transports. However, the above significant associations disappeared among female employees. CONCLUSIONS: Heavy OA, cycling to/from work, and LTPA were associated with lower risk of overall or abdominal overweight/obesity in male employees. Reducing leisure sitting time can also help male employees reduce the risk of abdominal overweight/obesity. More research on gender disparity in the risk of overweight and obesity should be done.

We present a powerful experimental-computational technology for inferring network models that predict the response of cells to perturbations, and that may be useful in the design of combinatorial therapy against cancer. The experiments are systematic series of perturbations of cancer cell lines by targeted drugs, singly or in combination. The response to perturbation is quantified in terms of relative changes in the measured levels of proteins, phospho-proteins and cellular phenotypes such as viability. Computational network models are derived de novo, i.e., without prior knowledge of signaling pathways, and are based on simple non-linear differential equations. The prohibitively large solution space of all possible network models is explored efficiently using a probabilistic algorithm, Belief Propagation (BP), which is three orders of magnitude faster than standard Monte Carlo methods. Explicit executable models are derived for a set of perturbation experiments in SKMEL-133 melanoma cell lines, which are resistant to the therapeutically important inhibitor of RAF kinase. The resulting network models reproduce and extend known pathway biology. They empower potential discoveries of new molecular interactions and predict efficacious novel drug perturbations, such as the inhibition of PLK1, which is verified experimentally. This technology is suitable for application to larger systems in diverse areas of molecular biology.

OBJECTIVE: To assess economic cost-effects for the screening programs of gastric cancer in a high risk population in northeastern China. METHODS: The data were collected from November 2001 to December 2003. The multi-stage sampling to define the screening group and the control group was applied in this study. Two stage screening programs were used in the study. An epidemiological survey and serum PG test were carried out in the first stage. The endoscopy and pathological examination were performed in the second stage screening. Effectiveness was assessed by the increased quality adjusted life-year (QALY) because of reduced gastric cancer deaths in screening. RESULTS: A total of 27,970 participants (n=7,128 screening group, n=20,842 control group) were enrolled in the survey. Twenty nine gastric cancer cases were detected in the screening group with 20 cases in the early stage and 9 cases in the advanced stage, respectively. Eighty six gastric cancer cases were detected in the control group, all of whom were in the advanced stage and had died before the study finished. The screening and treatment of 29 cases cost $152,227 and $5,249 per each case, respectively. The costs were $459 to gain per QALY. CONCLUSION: The screening program of gastric cancer used in our study is an economic and society-beneficial measure to detect gastric cancer in high risk area. The methods fit China's present economic development level.
RESUMO
OBJECTIVE: Using the health economics methodology to assess the screening program on gastric cancer in Zhuanghe high risk area for gastric cancer, from 2001 to 2003 and to assess the feasibility on cost of the screening program and to provide a basis for the popularization of the two-time gastric cancer screening methodology. METHODS: Three major techniques of medical economics namely cost-effective analysis (CEA), cost-benefit analysis (CBA) and cost-utility analysis (CUA) were used to assess the screening program. The screening program was composed of two steps: (1) epidemiological survey and detection of blood pepsinogen; (2) gastroscopy and biopsy of membrane. 'Number of deaths reduced' was used to evaluate the effect during cost-effective analysis while cost-benefit analysis would include the evaluation on the direct cost and indirect cost, direct benefit and indirect benefit as well as the cost-benefit ratio (CBR). During CUA, a questionnaire of WHOQOL-BREF was used to assess the value of the utility while the number of quality adjusted life year (QALY) saved by the screening program was also computed. The direct cost of per saved QALY was also calculated. RESULTS: Dada from CEA showed that: investing every 8448 Yuan on screening program and treatment in Zhuanghe high risk area of gastric cancer, one gastric cancer patient could be avoided. Results from CBA showed that: direct cost was 1,260,000 Yuan while indirect cost was 40 621 Yuan with direct benefit as 101 500 Yuan and indirect benefit as 1 540 979 Yuan. The total cost however, was 1,300,621 Yuan with total benefit as 2,555,979 Yuan and CBR was 1:1.97. Data from CUA showed that: a total number of 331.44 QALY was saved, 11.43 QALY was saved by reducing one death, 3802 Yuan per QALY was saved in high risk area of gastric cancer, through this screening program. CONCLUSION: The screening program of gastric cancer appeared to be an economic and society-beneficial measure regarding primary prevention in high risk area of gastric cancer. We also suggested that in the future, evaluations through health economics methodologies on different screening programs be carried out in the same population to solve the problem of comparability.
