The burden of depression,anxiety and schizophrenia among the older population in ageing and aged countries:an analysis of the Global Burden of Disease Study 2019

Background Depression,anxiety and schizophrenia among older persons have become global public health challenges.However,the burden of these disorders in ageing and aged countries has not been analysed.Aims To investigate the burden of depression,anxiety and schizophrenia among older adults in ageing and aged countries.Methods Using data from the Global Burden of Disease Study 2019,we calculated the estimated annual percentage change(EAPC)in the age-standardised incidence rates(ASiR)and age-standardised disability-adjusted life years(DALYs)rates(ASDR)for depression,anxiety and schizophrenia of older people in ageing countries(China,India,Indonesia)and aged countries(Japan,Italy,Portugal)between 1990 and 2019.Trends in incidence and DALYs were analysed by gender and age.Results In 2019,the highest incidence of depression,anxiety and schizophrenia in the older population in aged countries was in Japan(927271.3(752552.3-1125796.5),51498.2(37625.7-70487.3)and 126.0(61.0-223.2),respectively),while the highest incidence in ageing countries was in China(5797556.9(4599403.4-7133006.5),330256.1(246448.9-445987.4)and 1067.7(556.2-1775.9),respectively).DALYs for these disorders were similar,with the highest in Japan and China.From 1990 to 2019,the ASIR for depressive disorders decreased in aged countries but increased in ageing countries;the ASIR for anxiety disorders and schizophrenia declined in both ageing and aged countries.The ASDR for depressive disorders was consistent with the ASIR but not for anxiety disorders and schizophrenia.The ASIR for depressive disorders was higher in older women,while the opposite was observed in anxiety disorders and schizophrenia.Notably,the conditions of burden of depressive disorders,anxiety disorders and schizophrenia in the 65-70-year-old age group were the most burdensome.Conclusions The incidence and DALYs of these three mental disorders increased while exhibiting differences between ageing and aged countries.Raising awareness about formulating health policies for preventing and treating mental disorders in the older population is necessary to reduce the future burden posed by the ageing challenge.

Ferroptosis biomarkers predict tumor mutation burden's impact on prognosis in HER2-positive breast cancer

BACKGROUND Ferroptosis has recently been associated with multiple degenerative diseases.Ferroptosis induction in cancer cells is a feasible method for treating neoplastic diseases.However,the association of iron proliferation-related genes with prognosis in HER2+breast cancer(BC)patients is unclear.AIM To identify and evaluate fresh ferroptosis-related biomarkers for HER2+BC.METHODS First,we obtained the mRNA expression profiles and clinical information of HER2+BC patients from the TCGA and METABRIC public databases.A four gene prediction model comprising PROM2,SLC7A11,FANCD2,and FH was subsequently developed in the TCGA cohort and confirmed in the METABRIC cohort.Patients were stratified into high-risk and low-risk groups based on their median risk score,an independent predictor of overall survival(OS).Based on these findings,immune infiltration,mutations,and medication sensitivity were analyzed in various risk groupings.Additionally,we assessed patient prognosis by combining the tumor mutation burden(TMB)with risk score.Finally,we evaluated the expression of critical genes by analyzing single-cell RNA sequencing(scRNA-seq)data from malignant vs normal epithelial cells.RESULTS We found that the higher the risk score was,the worse the prognosis was(P<0.05).We also found that the immune cell infiltration,mutation,and drug sensitivity were different between the different risk groups.The highrisk subgroup was associated with lower immune scores and high TMB.Moreover,we found that the combination of the TMB and risk score could stratify patients into three groups with distinct prognoses.HRisk-HTMB patients had the worst prognosis,whereas LRisk-LTMB patients had the best prognosis(P<0.0001).Analysis of the scRNAseq data showed that PROM2,SLC7A11,and FANCD2 were significantly differentially expressed,whereas FH was not,suggesting that these genes are expressed mainly in cancer epithelial cells(P<0.01).CONCLUSION Our model helps guide the prognosis of HER2+breast cancer patients,and its combination with the TMB can aid in more accurate assessment of patient prognosis and provide new ideas for further diagnosis and treatment.

Cardiovascular risk burden and disability:findings from the International Mobility in Aging Study(IMIAS)

BACKGROUND The association of cardiovascular risk burden with disability is unclear.We examined the association between trajectories of the Framingham general cardiovascular disease risk score(FGCRS)with the trajectories of limitations of physical function in older adults.METHODS A total of 1219 participants with no disabilities from the International Mobility in Aging Study(IMIAS)study who had up to three repeated measures of FGCRS between 2012–2016 and without a history of stroke or coronary heart disease at baseline and follow-up were included.FGCRS at baseline was assessed and categorized into tertiles.Physical function was evaluated with the Short Physical Performance Battery(SPPB).The data were analyzed using linear mixed-effects models.RESULTS At baseline,FGCRS ranged between 3–94(mean score:24±15.8),participants were 32(2.6%),502(41.2%)and 685(56.2%)in lowest,middle,and highest tertiles,respectively.In the trajectories of limitations of physical function,the lowest FGCRS had no differences,while the middle and highest had a decrease in physical performance between 2012–2014(P=0.0001).Age,being female,living in Andes Mountains,having middle and highest FGCRS,higher alcohol consumption,being obese,lack of exercise and cognitive impairment increase the probability of disability(P<0.05).Alternatively,living in more developed regions and having a higher educational level reduced the probability of disability during the follow-up time(P<0.05).CONCLUSIONS Higher cardiovascular risk burden is associated with decreased physical performance,especially in gait.Results suggest SPPB may provide a measure of cardiovascular health in older adults.

Cardiovascular risk burden,dementia risk and brain structural imaging markers:a study from UK Biobank

Background Cardiovascular risk burden is associated with dementia risk and neurodegeneration-related brain structure,while the role of genetics and incident cardiovascular disease(CVD)remains unclear.Aims To examine the association of overall cardiovascular risk burden with the risk of major dementia subtypes and volumes of related brain regions in a large sample,and to explore the role of genetics and CVD onset.Methods A prospective study among 354 654 participants free of CVD and dementia(2006-2010,mean age 56.4 years)was conducted within the UK Biobank,with brain magnetic resonance imaging(MRl)measurement availablefor 15104participants since 2014.CVD risk burden was evaluated by the Framingham General Cardiovascular Risk Score(FGCRS).Dementia diagnosis was ascertained from inpatient and death register data.Results Overamedian 12.0-yearfollow-up,3998 all-cause dementia cases were identified.Higher FGCRS was associated with increasedall-cause dementia risk after adjusting for demographic,major lifestyle,clinical factors and the polygenic risk score(PRS)of Alzheimer's disease.Comparing the high versus low tertile of FGCRS,the odds ratios(ORs)and 95%confidence intervals(Cls)were 1.26(1.12 to 1.41)for all-cause dementia,1.67(1.33 to 2.09)for Alzheimer's disease and 1.53(1.07 to 2.16)for vascular dementia(all p_(treng)<0.05).Incident stroke and coronary heart disease accounted for 14%(95%Cl:9% to 21%)of the association between FGCRS and all-cause dementia.Interactions were not detected for FGCRS and PRS on the risk of any dementia subtype.We observed an 83%(95%Cl:47%to 128%)higher all-cause dementia risk comparing the high-high versus low-low FGCRS-PRS category.For brain volumes,higher FGCRS was associated with greater log-transformed white matter hyperintensities,smaller cortical volume and smaller grey matter volume.Conclusions Our findings suggest that the positive association of cardiovascular risk burden with dementia risk also applies to major dementia subtypes.The association of cardiovascular risk burden with all-cause dementia is largely independent of CVD onset and genetic predisposition to dementia.

Beyond Stitches: Analysis of Disease Burden in a Bangladeshi RMG Factory

Introduction: Bangladesh has experienced remarkable growth in RMG over the past 25 years. With the knitwear industry providing more than 4 million direct jobs, providing better occupational health and safety of workers remains a challenge. Aim of the study: The aim of the study was to analyze the disease burden of a RMG factory, and to highlight occupational health risks. Methods: A cross-sectional study design was employed for this analysis. A 17-month data entry (January 2020 - May 2021) was gathered from the factory in-house clinic. The socio-demographic and clinical diagnosis entries of 8421 entries were analyzed. Result: The population of the factory workers is 5370, where 40% (2148) are female workers and 60% (3222) are male workers. The mean age of respondents is 30 years, with a SD of ±7 years. Among the chief complaints, the most common was vomiting (14%;2262) fever (14%;2247), runny nose (11%;1842), cough (9%;1465), and loose motion (8%;1364). In the diagnosis categories, gastrointestinal diseases were more predominantly diagnosed (35%;2978), followed by viral fever (21%;1772), neurological diseases (16.5%;1389) and musculoskeletal disorders (9%;768). The average cost of medicine for each respondent is BDT 36. The factory covered costs of all medication for 99% (8380) of respondents. Only 0.5% (37) was referred to a tertiary hospital for further evaluation. Conclusion: Garments workers suffer mostly from long-term occupational health hazards. Factory owners and policy makers can contribute in various ways to improving primary healthcare options for workers.

Changes on Stroke Burden Attributable to Ambient Fine Particulate Matter in China

Objective In recent decades,China has implemented a series of policies to address air pollution.We aimed to assess the health effects of these policies on stroke burden attributable to ambient fine particulate matter(PM_(2.5)).Methods Joinpoint regression was applied to explore the temporal tendency of stroke burden based on data from the Global Burden of Disease 2019 study.Results The age-standardized rates of disability-adjusted life year(DALY)for stroke attributable to ambient PM2.5 in China,increased dramatically during 1990-2012,subsequently decreased at an annual percentage change(APC)of-1.98[95% confidence interval(CI):-2.26,-1.71]during 2012-2019.For ischemic stroke(IS),the age-standardized DALY rates doubled from 1990 to 2014,and decreased at an APC of-0.83(95%CI:-1.33,-0.33)during 2014-2019.Intracerebral hemorrhage(ICH)showed a substantial increase in age-standardized DALY rates from 1990 to 2003,followed by declining trends,with APCs of-1.46(95%CI:-2.74,-0.16)during 2003-2007 and-3.33(95%CI:-3.61,-3.06)during 2011-2019,respectively.Conversely,the age-standardized DALY rates for subarachnoid hemorrhage(SAH)generally declined during 1990-2019.Conclusion Our results clarified the dynamic changes of the ambient PM_(2.5)-attributable stroke burden in China during 1990-2019,highlighting the health effects of air quality improvement policies.

High-chromium vanadium-titanium magnetite all-pellet integrated burden optimization and softening-melting behavior based on flux pellets

High-chromium vanadium-titanium magnetite(HVTM)is a crucial polymetallic-associated resource to be developed.The allpellet operation is a blast furnace trend that aims to reduce carbon dioxide emissions in the future.By referencing the production data of vanadium-titanium magnetite blast furnaces,this study explored the softening-melting behavior of high-chromium vanadium-titanium magnetite and obtained the optimal integrated burden based on flux pellets.The results show that the burden with a composition of 70wt%flux pellets and 30wt%acid pellets exhibits the best softening-melting properties.In comparison to that of the single burden,the softening-melting characteristic temperature of this burden composition was higher.The melting interval first increased from 307 to 362℃and then decreased to 282℃.The maximum pressure drop(ΔPmax)decreased from 26.76 to 19.01 kPa.The permeability index(S)dropped from 4643.5 to 2446.8 kPa·℃.The softening-melting properties of the integrated burden were apparently improved.The acid pellets played a role in withstanding load during the softening process.The flux pellets in the integrated burden exhibited a higher slag melting point,which increased the melting temperature during the melting process.The slag homogeneity and the TiC produced by over-reduction led to the gas permeability deterioration of the single burden.The segregation of the flux and acid pellets in the HVTM proportion and basicity mainly led to the better softening-melting properties of the integrated burden.

A Novel Sensing Imaging Equipment Under Extremely Dim Light for Blast Furnace Burden Surface:Starlight High-Temperature Industrial Endoscope

Blast furnace(BF)burden surface contains the most abundant,intuitive and credible smelting information and acquiring high-definition and high-brightness optical images of which is essential to realize precise material charging control,optimize gas flow distribution and improve ironmaking efficiency.It has been challengeable to obtain high-quality optical burden surface images under high-temperature,high-dust,and extremelydim(less than 0.001 Lux)environment.Based on a novel endoscopic sensing detection idea,a reverse telephoto structure starlight imaging system with large field of view and large aperture is designed.Combined with a water-air dual cooling intelligent self-maintenance protection device and the imaging system,a starlight high-temperature industrial endoscope is developed to obtain clear optical burden surface images stably under the harsh environment.Based on an endoscope imaging area model,a material flow trajectory model and a gas-dust coupling distribution model,an optimal installation position and posture configuration method for the endoscope is proposed,which maximizes the effective imaging area and ensures large-area,safe and stable imaging of the device in a confined space.Industrial experiments and applications indicate that the proposed method obtains clear and reliable large-area optical burden surface images and reveals new BF conditions,providing key data support for green iron smelting.

Global Burden of Fungal Infections and Antifungal Resistance from 1961 to 2024: Findings and Future Implications

Background: Antifungal resistance (AFR) is a global public health problem with devastating effects, especially among immunocompromised individuals. Addressing AFR requires a One Health approach including Antifungal Stewardship (AFS). This study aimed to comprehensively review global studies published on fungal infections and AFR and to recommend solutions to address this growing problem. Materials and Methods: This was a narrative review that was conducted using published papers on fungal infections, AFR, and AFS between January 1961 and March 2024. The literature was searched using PubMed, Google Scholar, Web of Science, and EMBASE. Results: This found that there has been an increase in fungal infections globally, especially among immunocompromised patients. Due to this increase in fungal infections, there has been a proportionate increase in the use of antifungal agents to prevent and treat fungal infections. This increased use of antifungal agents has worsened the problem of AFR contributing to increased morbidity and mortality. Globally, fungal infections have contributed to 150 million infections annually and 1.7 million deaths per year. By the year 2023, over 3.8 million people died from fungal infections. Addressing AFR remains a challenge because the treatment of antifungal-resistant infections is difficult. Finally, the treatment of fungal infections is a global challenge exacerbated by the limited number of antifungal agents to treat invasive fungal infections. Conclusion: The results of this study indicated that fungal infections and AFR are prevalent across humans, animals, agriculture, and the environment. Addressing this problem requires the provision of solutions such as improving the awareness of AFR, conducting further research on the discovery of new antifungal agents, and implementing AFS programs. If this global problem is not addressed, the morbidity and mortality associated with AFR will continue to rise in the future.

Burden of gallstone disease in the United States population:Prepandemic rates and trends

BACKGROUND Gallstone disease is one of the most common digestive disorders in the United States and leads to significant morbidity,mortality,and health care utilization.AIM To expand on earlier findings and investigate prepandemic rates and trends in the gallstone disease burden in the United States using national survey and claims databases.METHODS The National Ambulatory Medical Care Survey,National Inpatient Sample,Nationwide Emergency Department Sample,Nationwide Ambulatory Surgery Sample,Vital Statistics of the United States,Optum Clinformatics®Data Mart,and Centers for Medicare and Medicaid Services Medicare 5%Sample and Medicaid files were used to estimate claims-based prevalence,medical care including cholecystectomy,and mortality with a primary or other gallstone diagnosis.Rates were age-adjusted(for national databases)and shown per 100000 population.RESULTS Gallstone disease prevalence(claims-based,2019)was 0.70%among commercial insurance enrollees,1.03%among Medicaid beneficiaries,and 2.09%among Medicare beneficiaries and rose over the previous decade.Recently,in the United States population,gallstone disease contributed to approximately 2.2 million ambulatory care visits,1.2 million emergency department visits,625000 hospital discharges,and 2000 deaths annually.Women had higher medical care rates with a gallstone disease diagnosis,but mortality rates were higher among men.Hispanics had higher ambulatory care visit and hospital discharge rates compared with Whites,but not mortality rates.Blacks had lower ambulatory care visit and mortality rates,but similar hospital discharge rates compared with whites.During the study period,ambulatory care and emergency department visit rates with a gallstone disease diagnosis rose,while hospital discharge and mortality rates declined.Among commercial insurance enrollees,rates were higher compared with national data for ambulatory care visits and hospitalizations,but lower for emergency department visits.Cholecystectomies performed in the United States included 605000 ambulatory laparoscopic,280000 inpatient laparoscopic,and 49000 inpatient open procedures annually.Among commercial insurance enrollees,rates were higher compared with national data for laparoscopic procedures.CONCLUSION The gallstone disease burden in the United States is substantial and increasing,particularly among women,Hispanics,and older adults with laparoscopic cholecystectomy as the mainstay treatment.Current practice patterns should be monitored for better health care access.

The burden and psychosocial impact on immediate caregivers of patients with spinal cord injury in a tertiary health facility,Edo State,Nigeria

Objective:This study aimed to assess the burden and psychosocial impact of spinal cord injury on the immediate caregivers at a tertiary health facility in Benin City,Edo State.Materials and Methods:A descriptive cross-sectional survey design was adopted among 73 family caregivers in the neurological ward of a tertiary health facility using a structured questionnaire as instrument of data collection.Data collected were analyzed using descriptive statistics and multiple logistic regression.Results:Findings revealed that an overall mean of 2.73 indicates that the burden on the caregivers was moderate with a moderate psychological impact(m=2.88)and a high sociological impact(m=3.12).Factors affecting the caregiving provided by immediate caregivers include social and household responsibilities(94.5%),financial situation(89.0%),family support(83.6%),and health status of the caregiver(80.8%).Age(odds ratio[OR]=5.67,95%confidence interval[CI]:1.23-27.17,P=0.027),education(OR=3.75,95%CI:1.05-13.39,P=0.041),and“others”(spouses,siblings,friends,or extended family members)(OR=3.167,95%CI:1.583-6.337,P=0.001)were predictors for high psychological impact while education(OR=0.074;95%CI:0.015-0.370,P=0.001)and caregiving role(OR=3.167;95%CI:0.1.583-6.337,P=0.001)high sociological impact.Conclusion:Majority of the caregivers experience moderate burden,moderate psychological impact,and high sociological impact.Understanding these factors is essential for developing targeted interventions and support services to address the unique needs of caregivers and mitigate the burden of caregiving on their psychosocial health.

Colorectal cancer’s burden attributable to a diet high in processed meat in the Belt and Road Initiative countries

BACKGROUND Colorectal cancer(CRC)plays a significant role in morbidity,mortality,and economic cost in the Belt and Road Initiative(“B and R”)countries.In addition,these countries have a substantial consumption of processed meat.However,the burden and trend of CRC in relation to the consumption of a diet high in processed meat(DHPM-CRC)in these“B and R”countries remain unknown.AIM To analyze the burden and trend of DHPM-CRC in the“B and R”countries from 1990 to 2019.METHODS We used the 2019 Global Burden of Disease Study to collate information regarding the burden of DHPM-CRC.Numbers and age-standardized rates(ASRs)of deaths along with the disability-adjusted life years(DALYs)were determined among the“B and R”countries in 1990 and 2019.Using joinpoint regression analysis,the average annual percent change(AAPC)was used to analyze the temporal trends of age-standardized DALYs rate(ASDALR)from 1990 to 2019 and in the final decade(2010–2019).RESULTS We found geographical differences in the burden of DHPM-CRC among“B and R”countries,with the three highest-ranking countries being the Russian Federation,China,and Ukraine in 1990,and China,the Russian Federation,and Poland in 2019.The burden of DHPM-CRC generally increased in most member countries from 1990 to 2019(all P<0.05).The absolute number of deaths and DALYs in DHPM-CRC were 3151.15[95%uncertainty interval(UI)665.74-5696.64]and 83249.31(95%UI 15628.64-151956.31)in China in 2019.However,the number of deaths(2627.57-2528.51)and DALYs(65867.39-55378.65)for DHPM-CRC in the Russian Federation has declined.The fastest increase in ASDALR for DHPM-CRC was observed in Vietnam,Southeast Asia,with an AAPC value of 3.90%[95%confidence interval(CI):3.63%-4.16%],whereas the fastest decline was observed in Kyrgyzstan,Central Asia,with an AAPC value of-2.05%(95%CI:-2.37%to-1.73%).A substantial upward trend in ASR of mortality,years lived with disability,years of life lost,and DALYs from DHPM-CRC changes in 1990-2019 and the final decade(2010-2019)for most Maritime Silk Route members in East Asia,South Asia,Southeast Asia,North Africa,and the Middle East,as well as Central Europe,while those of the most Land Silk Route members in Central Asia and Eastern Europe have decreased markedly(all P<0.05).The ASDALR for DHPM-CRC increased more in males than in females(all P<0.05).For those aged 50-74 years,the ASDALR for DHPM-CRC in 40 members exhibited an increasing trend,except for 20 members,including 7 members in Central Asia,Maldives,and 12 high or high-middle social development index(SDI)members in other regions(all P<0.05).CONCLUSION The burden of DHPM-CRC varies substantially across“B and R”countries and threatens public health.Relevant evidence-based policies and interventions tailored to the different trends of countries in SDIs or Silk Routes should be adopted to reduce the future burden of CRC in“B and R”countries via extensive collaboration.

Background:The Institute of Medicine has proposed that the amount of disease-specific research funding provided by the National Institutes of Health(NIH)be systematically and consistently compared with the burden of disease for society.Methods:We performed a cross-sectional study comparing estimates of disease-specific funding in 1996 with data on six measures of the burden of disease.

The relation between funding by the National Institutes of Health and the burden of disease

Background:The Institute of Medicine has proposed that the amount of disease-specific research funding provided by the National Institutes of Health(NIH)be systematically and consistently compared with the burden of disease for society.Methods:We performed a cross-sectional study comparing estimates of disease-specific funding in 1996 with data on six measures of the burden of disease.The measures were total mortality,years of life lost,and number of hospital days in 1994 and incidence,prevalence,and disability-adjusted life-years(one disability-adjusted life-year is defined as the loss of one year of healthy life to disease)in 1990.With the use of these measures as explanatory variables in a regression analysis,predicted funding was calculated and compared with actual funding.

A Prediction Model of Peasants’ Income in China Based on BP Neural Network

According to the related data affecting the peasants’ income in China in the years 1978-2008,a total of 13 indices are selected,such as agricultural population,output value of primary industry,and rural employees.Based on the standardized method and BP neural network method,the peasants’ income and the artificial neural network model are established and analyzed.Results show that the simulation value agrees well with the real value;the neural network model with improved BP algorithm has high prediction accuracy,rapid convergence rate and good generalization ability.Finally,suggestions are put forward to increase the peasants’ income,such as promoting the process of urbanization,developing small and medium-sized enterprises in rural areas,encouraging intensive operation,and strengthening the rural infrastructure and agricultural science and technology input.

Stomach cancer burden in China: Epidemiology and prevention

In 2020, stomach cancer was the fifth most commonly diagnosed cancer and the fourth leading cause of cancer-related death worldwide. Due to the relatively huge population base and the poor survival rate, stomach cancer is still a threat in China, and accounts for nearly half of the cases worldwide. Fortunately, in China, the incidence and mortality rates of stomach cancer presented a declining trend owing to the change of individual life styles and the persistent efforts to prevent stomach cancer from the governments at all levels. Helicobacter pylori(H. pylori)infection, poor eating habits, smoking, history of gastrointestinal disorders, and family history of stomach cancer are the main risk factors for stomach cancer in China. As a result, by taking risk factors for stomach cancer into account, specific preventive measures, such as eradicating H. pylori and implementing stomach cancer screening projects, should be taken to better prevent and decrease the burden of stomach cancer.

Impact of organophosphorous pesticide exposure on semen quality of Chinese peasants

Aim: To investigate the impact of organophosphorous pesticide exposure and other risk factors on the semen quality of Chinese peasants. Method: Questionnaire investigation, external genital examination and laboratory examination were conducted on 322 male peasants, including the exposed and the control groups of 161 subjects each. Results: Multivariate analysis showed that the educational level and the years of alcohol drinking influenced the semen volume. Compared with subjects of primary school education or lower, those with junior high school education had a higher semen volume (OR=1.961). Proportion of subjects with higher semen volume decreased with increased years of alcohol drinking (OR=0.962). Organophosphorous pesticide exposure decreased the number of forward progression sperm (OR=0.528), the sperm density (OR=0.266), the sperm viability (OR=0.398) and the percentage of normal morphology sperm (OR=0.281). A possible relationship was present between the season of semen collection and the number of forward progression sperm, sperm viability and percentage of normal morphology sperm. Compared with the summer data, the above three indices were higher in winter (OR being 2. 272, 4.060 and 5.249, respectively). Conclusion: Exposure to organophosphorous pesticide could damage the semen quality of the peasants. Education and alcohol drinking also affect the semen quality.

Time trends and gender disparities of Chinese cataract burden and their predictions

AIM:To evaluate the trends and changes in the number and rates of disability-adjusted life years(DALYs)and prevalence of cataract in China between 1990 and 2019,and to predict the trends of cataract burden from 2020 to 2030.METHODS:The Global Burden of Diseases(GBD)database was employed to collect the data on DALYs and the prevalence of cataract in China,which was distinguished by age and sex during the past three decades from 1990 to 2019,and then changes in the number and rates of cataract from 2020 to 2030 were predicted.All data were analyzed by the R program(version 4.2.2)and GraphPad Prism 9.0 statistics software.RESULTS:The number of DALYs of cataract increased from 449322.84 in 1990 to 1087987.61 in 2019,number of cataract cases increased from 5607600.94 in 1990 to 18142568.96 in 2019.The age-standardized DALY rates(ASDR)generally increased slightly[estimated annual percentage change(EAPC=0.1;95%CI:-0.24 to 0.45)],age-standardized prevalence rates(ASPR)also increased(EAPC=0.88;95%CI:0.6 to 1.15).Cataract burden increased with age and female gender.Among the causes of cataract,air pollution was the most important,followed by smoking,high fasting plasma glucose,and high body mass index(BMI).The burden of cataract is predicted to grow persistently from 2020 to 2030,the number of DALYs and prevalence for cataract will rise to 2336431 and 43698620 respectively by 2030,the ASDR is predicted to be 85/100000 and ASPR will be 1586/100000 in 2030,females will still be at greater risk of suffering from cataract than males.CONCLUSION:The burden of cataract in China kept rising from 1990 to 2019.Increasing age and female gender are risk factors for cataract.Air pollution,smoking,high fasting plasma glucose,and high BMI are associated with cataract.The burden of cataract in China will gradually increase from 2020 to 2030,the elderly women in particular need attention.Our results may be of help for providing reference strategies to reduce cataract burden in the near future.

Global Burden of Cardiovascular Disease Attributable to High Temperature in 204 Countries and Territories from 1990 to 2019

Objective This study aimed to estimate spatiotemporal variations of global heat-related cardiovascular disease(CVD)burden from 1990 to 2019.Methods Data on the burden of heat-related CVD were derived from the Global Burden of Disease Study 2019.Deaths and disability-adjusted life years(DALYs)were used to quantify heat-induced CVD burden.We calculated the age-standardized mortality rate(ASMR)and DALY rate(ASDR)per 100,000population to compare this burden across regions.Generalized linear models were applied to evaluate estimated annual percentage changes(EAPC)for temporal trends from 1990 to 2019.The correlation between the socio-demographic index(SDI)and age-standardized rate was measured using the Spearman rank test.Results Heat-induced CVD caused approximately 90 thousand deaths worldwide in 2019.Global ASMR and ASDR of heat-related CVD in 2019 were 1.17[95%confidence interval(CI):0.13-1.98]and 25.59(95%CI:2.07-44.17)per 100,000 population,respectively.The burden was significantly increased in middle and low-SDI regions and slightly decreased in high-SDI regions from 1990 to 2019.ASMR showed an upward trend,with the most considerable increase in low-latitude countries.We observed a negative correlation between SDI and EAPC in ASMR(rs=-0.57,P<0.01)and ASDR(rs=-0.59,P<0.01)among204 countries.Conclusion Heat-attributable CVD burden substantially increased in most developing countries and tropical regions.
