Trends in deaths and disability-adjusted life-years of stroke attributable to low physical activity worldwide, 1990-2019.

BACKGROUND: Low physical activity (LPA) is linked to the risk of stroke, but the disease burden of stroke attributable to LPA needs to be understood to develop effective preventive strategies. We aim to assess spatiotemporal trends in the global burden of stroke attributable to LPA from 1990 to 2019. METHODS: Based on the Global Burden of Disease, Injuries, and Risk Factors Study, our research examined deaths, the Disability-Adjusted Life Years (DALYs), the Age-Standardized Mortality Rate (ASMR), the Age-Standardized DALY Rate (ASDR), and the Estimated Annual Percentage Change (EAPC) for stroke attributable to LPA. RESULTS: Deaths and DALYs were on the rise worldwide from 1990 to 2019, with increases of 72.72% for the former and 67.41% for the latter; ASMR and ASDR decreased, with the ASMR-related EAPC of -1.61 (95% CI:-1.71--1.5) and ASDR-related EAPC of -1.35 (95% CI:-1.43--1.27); females had more numbers of deaths and DALYs, and the majorities of deaths and DALYs were shared by those aged ≥ 70. The highest burden rates were shared by North Africa, the Middle East, and Tropical Latin America; the ASMR-related EAPC was associated with the ASMR in 1990 (R = -0.26, P < 0.001) and the Socio-Demographic Index (SDI) across different countries in 2019 (R = -0.61, P < 0.001), respectively, and such patterns were similar to what ASDR and the ASDR-related EAPC had; the Human Development Index (HDI) in 2019 was associated with the ASMR-related EAPC (R = 0.63, P < 0.001) and the ASDR-related EAPC across different countries (R = -0.62, P < 0.001), respectively. CONCLUSIONS: Globally, deaths and DALYs of stroke attributable to LPA were on the rise, although their age-standardized rates presented downward over the past three decades; the burden of stroke attributable to LPA showed upward trends especially in those aged ≥ 70 and females in the regions of East Asia, North Africa, and the Middle East, which need more attention to the effects of physical activity on health interventions.

Cost-effectiveness analysis of autogenous arteriovenous fistula, arteriovenous graft, and tunneled-cuffed catheter for hemodialysis in patients with end-stage kidney disease in Southern China.

OBJECTIVES: To evaluate the cost-effectiveness of three permanent vascular accesses for maintenance hemodialysis patients from a hospital perspective throughout 5 years, which is the average life expectancy of patients with end-stage kidney disease. SUBJECTS AND METHODS: We conducted a EuroQol(EQ-5D) questionnaire survey between January 2021 and March 2021 with 250 patients to estimate the health utility of various states in patients under different hemodialysis vascular access. We designed a Markov model and conducted a cost-effectiveness analysis to compare the cost-effectiveness of three hemodialysis vascular access in Guangzhou throughout 5 years. RESULTS: The mean costs were US$44,481 with tunneled-cuffed catheter (TCC), and US$68,952 and US$59,247 with arteriovenous graft (AVG) and autogenous arteriovenous fistula (AVF), respectively. The mean quality-adjusted life-years (QALYs) was 1.41 with TCC, and 2.37 and 2.73 with AVG and AVF, respectively. AVG had an incremental cost-effectiveness ratio (ICER) of US$25,491 per QALY over TCC; AVF had an ICER of -US$26,958 per QALY over AVG. At a willingness to pay below US$10,633.8 per QALY, TCC is likely the most cost-effective vascular access. At any willingness to pay between US$10,633.8 and US$30,901.4 per QALY, AVF is likely the most cost-effective vascular access. CONCLUSION: These findings illustrate the value of AVF given its relative cost-effectiveness to other hemodialysis modalities. Although AVG costs much more than TCC for slightly higher QALYs than TCC, AVG still has a greater advantage over TCC for patients with longer life expectancy due to its lower probability of death.

Trends in Prevalence Cases and Disability-Adjusted Life-Years of Parkinson's Disease: Findings from the Global Burden of Disease Study 2019.

BACKGROUND: Parkinson's disease is a common, age-related progressive neurodegenerative disorder with considerable socioeconomic burdens, although the studies in incremental burdens to the disease's rapid growth are incomplete and lag behind. We aim to assess global burdens of Parkinson's disease based on a public database online. METHODS: Based on the Global Burden of Disease, Injuries, and Risk Factors Study, we screened a range of indicators including prevalence cases, disability-adjusted life-years (DALYs), age-standardized prevalence rates (ASPRs), and age-standardized DALY rate (ASDR). The join point regression was used to assess the indicators, wherein the ASPR and the ASDR were referred to temporal trends for burdens of Parkinson's disease. RESULTS: Prevalence cases of global Parkinson's disease were on the rise for 30 years, with an increase of 155.51% during 1990-2019. Temporal trend of ASDRs was on the rise during 1990-2002 but in decline during 2002-2019. The ASPRs had a turning point in 2017 and a decline during 2017-2019 (annual percentage change = -0.51%, p > 0.05). China, India, the USA, Japan, and Germany shared the five highest prevalence cases and DALYs in 2019. The Socio-Demographic Index (SDI) was in relation to a significantly positive ASPR (R = 0.61, p < 0.001) but not a significantly negative ASDR (R = -0.044, p = 0.53), respectively. CONCLUSIONS: In this study, a range of indicators for global burdens of Parkinson's disease were on the rise during 1990-2019. Tremendous efforts should be in place to prevent Parkinson's disease, especially among the populations of males, with advanced ages, in East Asia, and in regions with high SDI.
