Economic evaluation of automated external defibrillator deployment in public settings for out-of-hospital cardiac arrest: a systematic review.

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) is a major issue in aging populations. The use of automatic external defibrillators (AEDs) in public places improves cardiac arrest survival rates. The purpose of this study is to review economic evaluation studies of the use of AED technology in public settings for cardiac arrest resuscitation. METHODS: Our search covered 1990-2021 and included PubMed, Cochrane Library, Embase, Scopus, and Web of Science. We included studies that analyzed cost-effectiveness, cost-utility and cost-benefit of the AED technology. Also, we performed the quality assessment of the studies through the checklist of quality assessment standard of health economic studies (QHES). RESULTS: Our inclusion criteria were met by 25 studies. AEDs are found to be cost-effective in places with a high occurrence of cardiac arrest. In addition, proper integration of drones with AEDs into existing systems has the potential to significantly improve OHCA survival rates. CONCLUSION: The present study found that putting AEDs in high-cardiac arrest and crowded areas reduces average costs. Despite this, the costs associated with acquiring and maintaining AEDs prevent their widespread use. Further research is needed to evaluate feasibility and explore innovative strategies for AED maintenance and accessibility.

Cost-Effectiveness analysis of endovascular versus open repair in patients with abdominal aortic aneurysm in Iran: A Cross-Sectional study.

OBJECTIVES: Abdominal aortic aneurysm is one of the most important cardiovascular diseases, especially in the elderly. People with this disease are at risk of rupture of the abdominal aorta and death. The present study was conducted with the aim of analyzing the cost effectiveness of endovascular repair compared to open surgery in abdominal aortic aneurysm patients in Iran. METHODS: A Markov chain model was developed based on the use of endovascular repair and open surgery. The base-case patient was defined as a 65-year-old man presenting with abdominal aortic aneurysm diameter greater than 5 cm. The determination of costs was from the perspective of the public sector provider. QALY was used to calculate the effectiveness. Incremental cost-effectiveness ratio (ICER) and TreeAge software were used for cost-effectiveness analysis. The follow-up period was 10 years and the willingness to pay (WTP) was determined as three times the Gross domestic product (GDP) per capita. RESULT: At the end of year 10, the endovascular aneurysm repair (EVAR) strategy gained 1,318,313,559 Iranian Rial (IRR) (67885.29$) in cost and 3.57 QALYs in effectiveness. In contrast, the use of the open surgery repair (OSR) strategy gained 1,186,761,858 IRR (61111.16$) in cost and 3·32 QALYs in effectiveness. The incremental cost-effectiveness ratio, comparing EVAR versus OSR, was 53, 346, 3757 IRR (178.36$) per QALYs, which is lower than the proposed WTP, indicating that EVAR is more expensive and more effective. Based on the Monte Carlo simulation test, EVAR is the preferred strategy in 58.6% of the population. CONCLUSION: Endovascular repair has a relative superiority compared to open surgery, and the probability of the effectiveness of endovascular repair compared to open surgery does not change with increasing willingness to pay.

The Global, Regional, and National Burden of Adult Lip, Oral, and Pharyngeal Cancer in 204 Countries and Territories: A Systematic Analysis for the Global Burden of Disease Study 2019.

Importance: Lip, oral, and pharyngeal cancers are important contributors to cancer burden worldwide, and a comprehensive evaluation of their burden globally, regionally, and nationally is crucial for effective policy planning. Objective: To analyze the total and risk-attributable burden of lip and oral cavity cancer (LOC) and other pharyngeal cancer (OPC) for 204 countries and territories and by Socio-demographic Index (SDI) using 2019 Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study estimates. Evidence Review: The incidence, mortality, and disability-adjusted life years (DALYs) due to LOC and OPC from 1990 to 2019 were estimated using GBD 2019 methods. The GBD 2019 comparative risk assessment framework was used to estimate the proportion of deaths and DALYs for LOC and OPC attributable to smoking, tobacco, and alcohol consumption in 2019. Findings: In 2019, 370 000 (95% uncertainty interval [UI], 338 000-401 000) cases and 199 000 (95% UI, 181 000-217 000) deaths for LOC and 167 000 (95% UI, 153 000-180 000) cases and 114 000 (95% UI, 103 000-126 000) deaths for OPC were estimated to occur globally, contributing 5.5 million (95% UI, 5.0-6.0 million) and 3.2 million (95% UI, 2.9-3.6 million) DALYs, respectively. From 1990 to 2019, low-middle and low SDI regions consistently showed the highest age-standardized mortality rates due to LOC and OPC, while the high SDI strata exhibited age-standardized incidence rates decreasing for LOC and increasing for OPC. Globally in 2019, smoking had the greatest contribution to risk-attributable OPC deaths for both sexes (55.8% [95% UI, 49.2%-62.0%] of all OPC deaths in male individuals and 17.4% [95% UI, 13.8%-21.2%] of all OPC deaths in female individuals). Smoking and alcohol both contributed to substantial LOC deaths globally among male individuals (42.3% [95% UI, 35.2%-48.6%] and 40.2% [95% UI, 33.3%-46.8%] of all risk-attributable cancer deaths, respectively), while chewing tobacco contributed to the greatest attributable LOC deaths among female individuals (27.6% [95% UI, 21.5%-33.8%]), driven by high risk-attributable burden in South and Southeast Asia. Conclusions and Relevance: In this systematic analysis, disparities in LOC and OPC burden existed across the SDI spectrum, and a considerable percentage of burden was attributable to tobacco and alcohol use. These estimates can contribute to an understanding of the distribution and disparities in LOC and OPC burden globally and support cancer control planning efforts.

Cost-effectiveness of brentuximab vedotin in Hodgkin lymphoma: a systematic review.

PURPOSE: This study aimed to systematically review and critically appraise cost-effectiveness studies on Brentuximab vedotin (BV) in patients with Hodgkin lymphoma (HL). METHODS: The PubMed, Scopus, Web of Science core collection, and Embase databases were searched until July 3, 2022. We included published full economic evaluation studies on BV for treating patients with HL. The methodological quality of the studies was assessed using the Quality of Health Economic Studies (QHES) checklist. Meanwhile, we used qualitative synthesis to analyze the findings. We converted the incremental cost-effectiveness ratios (ICERs) to the value of the US dollar in 2022. RESULTS: Eight economic evaluations met the study's inclusion criteria. The results of three studies that compared BV plus doxorubicin, vinblastine, and dacarbazine (BV + AVD) front-line therapy with doxorubicin, bleomycin, vincristine, and dacarbazine (ABVD) showed that BV is unlikely to be cost-effective as a front-line treatment in patients advanced stage (III or IV) HL. Four studies investigated the cost-effectiveness of BV in patients with relapsed or refractory (R/R) HL after autologous stem cell transplantation (ASCT). BV was not cost-effective in the reviewed studies at accepted thresholds. In addition, the adjusted ICERs ranged from $65,382 to $374,896 per quality-adjusted life-year (QALY). The key drivers of cost-effectiveness were medication costs, hazard ratio for BV, and utilities. CONCLUSION: Available economic evaluations show that using BV as front-line treatment or consolidation therapy is not cost-effective based on specific ICER thresholds for patients with HL or R/R HL. To decide on this orphan drug, we should consider other factors such as existence of alternative treatment options, clinical benefits, and disease burden.

Economical Evaluation of Cancer Types Using Intensity-Modulated Radiation Therapy Compared to 3D Conformal Radiation Therapy: A Systematic Review.

Background: Cancer is the second most common cause of death worldwide. Economic evaluation of cancer treatment to reduce costs can save the health care system millions of dollars while optimizing care. Therefore, this systematic review aimed to study the economic evaluation of cancer treatment using intermediate intensity radiation therapy (IMRT) compared to conventional 3D conformal radiation therapy (3D-CRT). Methods: Literatures from PubMed, Embase, Cochran Library, Google scholar, Scopus and Iranian databases were retrieved since Jan 2000 to Apr 2020 for eligible English studies. The quality of the studies was evaluated using Cheers' checklist and then the textual data were analyzed manually by content analysis method. Results: Overall, 1790 articles were retrieved, of which 12 studies were reviewed. The article quality score ranged from 14.5 to 23 out of a maximum of 24 points. Eleven studies referred to cost-effectiveness analysis and one study referred to cost-utility analysis. Studies have been conducted in the United States, Canada, Australia, Brazil, the Netherlands, the United Kingdom, and Hungary. IMRT appears to be a cost-effective treatment strategy for rectal cancer, soft tissue sarcoma, and localized carcinoma of the pharynx, and for prostate cancer in terms of prolonging survival, but it is a cost-effective treatment strategy for head cancer. In addition, the neck was not in India's cancer control program. Conclusion: The results can help to decide whether to use radiation therapy and radiotherapy in the standard treatment path. Furthermore, they underline that IMRT treatment technique was cost effective for a long-time care service.

Cost-Effectiveness of Atrial Fibrillation Screening Strategies: A Systematic Review.

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia. AF is associated with an increased risk of stroke. We aimed to review systematically the cost-effectiveness of screening strategies for patients with AF. Methods: To find related research and articles, articles published in Iranian and international databases by using a combination of MeSH (Medical Subject Headings) terms and based on inclusion and exclusion criteria were searched and reviewed until Dec 2020. The main outcome measures of the final articles were incremental cost-effectiveness ratios (ICER) per gained or additional quality-adjusted life years (QALYs), additional case detected, and avoided stroke. Results: Out of 3,360 studies found, finally, fifteen studies were included in the research. The lowest ICER numerical value was 78.39 for AF screening using ECG for 65-85 yr old Japanese women. The highest value of this index is equal to 70864.31 for performing ECG monitoring for more than 60 d for Canadians over 80 yr without AF history. In two studies, the results were expressed with the years of life gained (YLG measure. Of course, in one study, the results were not reported with this measure, and in one study, the results were reported with ICER. Conclusion: Most of the studies acknowledged the cost-effectiveness of different AF screening strategies. However, studies that confirmed the cost-effectiveness of population-based screening were more than studies that confirmed the cost-effectiveness of other screening strategies.

Cost-Effectiveness Rivaroxaban versus Enoxaparin for Prevention of Venous Thromboembolism after Knee Replacement Surgery in Iran.

Background: The highest risk of developing venous thromboembolism (VTE) is seen in patients who have undergone orthopedic surgery. One of the most common methods to reduce the risk of thromboembolism in these patients is anticoagulant prophylaxis. Rivaroxaban is one of the anticoagulants that has a lower cost than other anticoagulants and has a significant effect on people's quality of life as it is edible. The study aimed to determine the cost-effectiveness of rivaroxaban as compared with enoxaparin for venous thromboembolism prophylaxis in knee replacement patients in Iran. Methods: It was a quantitative and economic evaluation study with a cost-effectiveness approach and an applied study because its results could be used directly for policy-making and decision-making in the health system. The study was conducted in 2019 and 2020. This study considered the health system perspective. The study population included all knee replacement patients. The sample included 203 patients referred to Shafa Yahyaeian Hospital and 300 patients referred to Rasoul Hospital in Tehran. The study was conducted in two steps. A systematic review of studies was conducted in the first step. The CHEERS checklist was used to evaluate the quality of the studies in the systematic review. The EQ-5D questionnaire was used in the second step to calculate the QALY, and the cost collection form was used to calculate the direct medical cost. The data were analyzed through a decision tree, and Stata and Tree age pro softwares were the analysis tools. Also, according to the per capita GDP index for Iran in 2018, the incremental cost-effectiveness threshold was considered to be $10,000. Results: The results of this study showed that during the prophylaxis period, rivaroxaban was one and a half times less costly than enoxaparin. Quality of life in uncomplicated conditions were 0.85 QALY for rivaroxaban and 0.69 QALY for enoxaparin. Based on the results of this study, the cost of rivaroxaban during the prophylaxis was $ 160.97 and the quality of life was 0.85 QALY and the cost of enoxaparin was $ 276.07 and the quality of life was 0.69 QALY. The cost difference between the two interventions was $ 115.09 and the outcome difference was 0.16 QALY. The incremental cost-effectiveness ratio was $ 189.40 for rivaroxaban and $ 416.28 for enoxaparin. According to the results of this study, rivaroxaban reduced the duration of hospitalization by an average of 2 days in asymptomatic patients (prophylaxis period) compared to enoxaparin. Conclusion: Rivaroxaban, an oral medication, reduced costs and increased the quality of life in people undergoing knee replacement surgery compared with an enoxaparin injection vial. This drug was less costly for the patient and health systems and its use was cost-effective as a thromboprophylaxis drug following knee replacement surgery.

Safety and Effectiveness of Endodermal Radiofrequency for Skin Rejuvenation: A Systematic Review.

BACKGROUND: With the advent of new technologies, the demand for non-invasive and effective procedures to treat skin laxity has increased. In this research, we aimed to review studies conducted on the safety and effectiveness of endodermal radiofrequency (ER) for skin rejuvenation. METHODS: We searched the databases of Embase, PubMed, Scopus, and Google Scholar from 2000 to 2020 to conduct a systematic review based on the PRISMA statement. Screening of titles, abstracts, and full-text articles was performed independently by two reviewers according to inclusion and exclusion criteria. RESULTS: This study showed that ER resulted in improvement in wrinkles and sagging, reduction of fat, tightening of skin of the face, neck, and jawline, improvement in skin elasticity, pigmentation, contouring of the body, and epidermal thickness decrease. ER technology leads to a significant and satisfactory improvement in skin rejuvenation, lower contouring of skin of the face and neck, as well as patients' satisfaction. Side effects of ER are temporary, and usually disappear spontaneously after a few days to one month. CONCLUSION: Cosmetic services providers can use this effective and safe technology to treat skin laxity and skin rejuvenation as a substitute for surgery.

The Economic Burden of Acute Myeloid Leukemia in Iran.

Background: Cancer imposes a significant economic burden on the health system and society. Acute myeloid leukemia (AML) is the third deadliest leukemia and is one of the leading health problems worldwide. The present study aimed to estimate the economic burden of AML in Iran for 2020. Methods: In this study, we estimated a prevalence-based on the cost-of-illness of the AML in Iran. A societal perspective was considered, in which the direct costs and productivity losses with the adoption of the human capital approach in the AML cases were estimated for 2020. Moreover, in the present study, several resources including national cancer registry reports, hospital records, occupational data, and interviews with experts were cited. Results: Approximately 98% of patients with AML received induction therapy. The AML economic burden was $33,243,107.39. Indirect costs accounted for 60% (21,593,764.4$) of this amount, and direct medical costs and direct non-medical costs make up for 19% (6,359,380.88$) and 16% (5,289,962.11$) of this estimated economic burden, respectively. Conclusion: The economic burden of AML in Iran is very remarkable and due to the increasing prevalence of this disease, it is expected to increase gradually. Having insights into the costs associated with the disease provide an excellent opportunity for health policymakers and managers to effectively improve resource allocation.

Mapping age- and sex-specific HIV prevalence in adults in sub-Saharan Africa, 2000-2018.

BACKGROUND: Human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) is still among the leading causes of disease burden and mortality in sub-Saharan Africa (SSA), and the world is not on track to meet targets set for ending the epidemic by the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the United Nations Sustainable Development Goals (SDGs). Precise HIV burden information is critical for effective geographic and epidemiological targeting of prevention and treatment interventions. Age- and sex-specific HIV prevalence estimates are widely available at the national level, and region-wide local estimates were recently published for adults overall. We add further dimensionality to previous analyses by estimating HIV prevalence at local scales, stratified into sex-specific 5-year age groups for adults ages 15-59 years across SSA. METHODS: We analyzed data from 91 seroprevalence surveys and sentinel surveillance among antenatal care clinic (ANC) attendees using model-based geostatistical methods to produce estimates of HIV prevalence across 43 countries in SSA, from years 2000 to 2018, at a 5 × 5-km resolution and presented among second administrative level (typically districts or counties) units. RESULTS: We found substantial variation in HIV prevalence across localities, ages, and sexes that have been masked in earlier analyses. Within-country variation in prevalence in 2018 was a median 3.5 times greater across ages and sexes, compared to for all adults combined. We note large within-district prevalence differences between age groups: for men, 50% of districts displayed at least a 14-fold difference between age groups with the highest and lowest prevalence, and at least a 9-fold difference for women. Prevalence trends also varied over time; between 2000 and 2018, 70% of all districts saw a reduction in prevalence greater than five percentage points in at least one sex and age group. Meanwhile, over 30% of all districts saw at least a five percentage point prevalence increase in one or more sex and age group. CONCLUSIONS: As the HIV epidemic persists and evolves in SSA, geographic and demographic shifts in prevention and treatment efforts are necessary. These estimates offer epidemiologically informative detail to better guide more targeted interventions, vital for combating HIV in SSA.

Economic evaluation of single-photon emission-computed tomography versus stress echocardiography in stable chest pain patients.

The timely diagnosis of coronary artery disease (CAD) is an important medical problem. This study aims to assess the cost-effectiveness of Single-Photon Emission-Computed Tomography (SPECT) compared with stress echocardiography in stable chest pain patients. An economic evaluation study was conducted to assess the cost-effectiveness of SPECT versus stress echocardiography in stable chest pain patients without known CAD between April 1, 2017, and September 1, 2018 in Tehran, Iran. This study was performed from a societal perspective. The incremental cost-effectiveness ratio was calculated using a decision tree model. In addition, the robustness of results was examined by deterministic and probabilistic sensitivity analysis. This study showed that the expected cost and expected QALY for Stress echocardiography was $1106.75 and 0.83 respectively. Also, SPECT had expected cost and expected QALY equal to $1622.39 and 0.80 respectively. Finally, Stress echocardiography was the dominant strategy for CAD, with a lower cost and greater effectiveness than SPECT. The stress echocardiography can saved $18,528.17 per QALY. A deterministic and probabilistic sensitivity analysis confirmed the robustness of the results. Stress echocardiography was a more cost-effective method for diagnosing CAD disease in stable chest pain patients without known CAD compared to SPECT.

Cost-Effectiveness of Multiparametric Magnetic Resonance Imaging and Targeted Biopsy Versus Systematic Transrectal Ultrasound-Guided Biopsy for Prostate Cancer Diagnosis: A Systematic Review.

OBJECTIVES: This study aimed to systematically review the cost-effectiveness studies of multiparametric magnetic resonance imaging (mpMRI)-guided biopsy (MRGB) compared with systematic transrectal ultrasonography (TRUS)-guided biopsy for diagnosing prostate cancer (PCa). METHODS: PubMed, Web of Science core collection, Embase and Scopus, and reference lists of the included studies were searched with no date and language restrictions through January 2020 for full economic evaluation studies (cost-effectiveness, cost-utility analysis, cost-benefit analysis) that assessed mpMRI and MRGB compared with systematic TRUS-guided biopsy or other sequential biopsy strategies in men undergoing initial prostate biopsy or men with previous negative prostate biopsy, with clinical suspicion of PCa based on abnormal prostate-specific antigen or digital rectal examination increase or both. Data were tabulated and analyzed using narrative synthesis. The reporting quality of included studies was assessed using the Consolidated Health Economic Evaluation Reporting Standards checklist. This systematic review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. RESULTS: Finally, 9 studies were included. All studies were conducted in high-income countries. All studies found that mpMRI and MRGB was cost-effective in the initial and before repeat biopsy in men with previous negative biopsy. The cognitive-targeted TRUS-guided biopsy was cost-effective in the initial biopsy (dominant or cost-effective at willingness-to-pay threshold of the countries); it was not evaluated for repeat biopsy in men. The direct in-bore magnetic resonance imaging (MRI)-guided biopsy was cost-effective for the initial biopsy (€323 per quality-adjusted life-year gained). The superiority of one of the targeted biopsy approaches (fusion, cognitive, or in-bore) over other approaches has not yet been established. CONCLUSIONS: This study showed that pre-TRUS-guided biopsy MRI is more cost-effective than TRUS-guided biopsy alone. Furthermore, the use of MRI-ultrasound fusion targeted biopsy in the diagnosis of PCa in the initial biopsy and repeat biopsy and cognitive-targeted TRUS-guided biopsy in the initial biopsy is cost-effective.

Hospital Expenditure at the End-of-Life: A Time-to-Death Approach.

BACKGROUND: In recent years the use of time to death (TTD) variables in the modeling of individual health expenditures has been of interest to health economics researchers. The aim of this study was to investigate the effect of age and TTD on hospital inpatient expenditure (HIE). METHODS: We used a claims database from Iran Health Insurance Organization of Tehran city that includes considerable proportion of Tehran residents and contains information on insured individuals' HIE. We included HIE of all insured decedents (30 to 90 years old) who died during March 2013 and March 2014 (n=1018). No sampling was required. According to the decedents' date of death, we extracted their last 24 months HIE. The period of time March 30, 2011 until March 30, 2014 (3 years) was used to guarantee a full 24 months of observations for decedents. A two-part econometric model was employed to investigate the effect of age, TTD, and some demographic variables on probability and conditional amount of individuals' hospital expenditure. Stata software (version 16.0) was used for data processing and analysis. RESULTS: Our results demonstrated that the month-based TTDs especially near months before death of decedents (TTD1 to TTD10) significantly affected both probability and conditional amount of HIE. One month before death incurred more HIE than the rest of the months. A further interesting finding is that after including TTD, age variable as a conditional driver of HIE loses its direct effect on decedents' HIE, but age TTD interaction effect on HIE is still positive and statistically significant. CONCLUSION: The results confirm that TTD as a proxy of mortality indicator has a considerable effect on decedents' HIE. The age variable has not directly affected decedents' HIE but indirectly and through its interaction with TTD has a statistically significant effect on HIE. In addition to age, policy-makers should consider TTD to make better predictions of future HIE.

Cost-effectiveness of osimertinib in the treatment of advanced EGFR-mutated non-small cell lung cancer: a systematic review.

BACKGROUND: The most common type of lung cancer is advanced and mutant non-small cell lung cancer (NSCLC). Although targeted tyrosine kinase inhibitors (TKIs) have reconstructed the care of these patients, the resistance of TKIs to the secondary EGFR-T790M mutation in advanced or metastatic NSCLC led to the introduction of the third generation of them, like osimertinib. Osimertinib has represented a remarkable increase in progression-free survival (PFS) and a decrease in death and hazard ratios in patients with required T790 mutation and sensitizing EGFR mutation without T790M. We aimed to evaluate the cost-effectiveness of osimertinib for the treatment of these patients compared to chemotherapy or immunotherapy with the last generations of EGFR-TKIs. AREAS COVERED: Electronic searches were conducted on PubMed, Embase, Science Direct, Scopus, , Web of Knowledge, NHSEED, NHS Health Technology assessment (CRD), and Cost-Effectiveness Analysis Registry databases. Related articles were reviewed from January 2015 to the end of August 2020. Out of 2708 initial studies, 10 articles had the inclusion criteria. EXPERT OPINION: Although osimertinib improves the quality of life and PFS for the mentioned patients based on its greater efficacy compared to standard EGFR-TKIs and chemotherapy, its high cost prevents considering it a cost-effective option. And, since most entered studies have been done in developed countries, it certainly does not true to extend these results to low-income and developing countries. Therefore, further studies in those countries are needed to evaluate the cost-effectiveness of osimertinib for sensitizing EGFR mutation without T790M and required T790M in advanced or metastatic NSCLC.

Cancer Incidence, Mortality, Years of Life Lost, Years Lived With Disability, and Disability-Adjusted Life Years for 29 Cancer Groups From 2010 to 2019: A Systematic Analysis for the Global Burden of Disease Study 2019.

IMPORTANCE: The Global Burden of Diseases, Injuries, and Risk Factors Study 2019 (GBD 2019) provided systematic estimates of incidence, morbidity, and mortality to inform local and international efforts toward reducing cancer burden. OBJECTIVE: To estimate cancer burden and trends globally for 204 countries and territories and by Sociodemographic Index (SDI) quintiles from 2010 to 2019. EVIDENCE REVIEW: The GBD 2019 estimation methods were used to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life years (DALYs) in 2019 and over the past decade. Estimates are also provided by quintiles of the SDI, a composite measure of educational attainment, income per capita, and total fertility rate for those younger than 25 years. Estimates include 95% uncertainty intervals (UIs). FINDINGS: In 2019, there were an estimated 23.6 million (95% UI, 22.2-24.9 million) new cancer cases (17.2 million when excluding nonmelanoma skin cancer) and 10.0 million (95% UI, 9.36-10.6 million) cancer deaths globally, with an estimated 250 million (235-264 million) DALYs due to cancer. Since 2010, these represented a 26.3% (95% UI, 20.3%-32.3%) increase in new cases, a 20.9% (95% UI, 14.2%-27.6%) increase in deaths, and a 16.0% (95% UI, 9.3%-22.8%) increase in DALYs. Among 22 groups of diseases and injuries in the GBD 2019 study, cancer was second only to cardiovascular diseases for the number of deaths, years of life lost, and DALYs globally in 2019. Cancer burden differed across SDI quintiles. The proportion of years lived with disability that contributed to DALYs increased with SDI, ranging from 1.4% (1.1%-1.8%) in the low SDI quintile to 5.7% (4.2%-7.1%) in the high SDI quintile. While the high SDI quintile had the highest number of new cases in 2019, the middle SDI quintile had the highest number of cancer deaths and DALYs. From 2010 to 2019, the largest percentage increase in the numbers of cases and deaths occurred in the low and low-middle SDI quintiles. CONCLUSIONS AND RELEVANCE: The results of this systematic analysis suggest that the global burden of cancer is substantial and growing, with burden differing by SDI. These results provide comprehensive and comparable estimates that can potentially inform efforts toward equitable cancer control around the world.

The cost-effectiveness of B-type natriuretic peptide-guided care in compared to standard clinical assessment in outpatients with heart failure in Tehran, Iran.

BACKGROUND: B-type natriuretic peptide (BNP) is commonly used as a diagnostic method for patients with heart failure. This study was designed to evaluate the cost-effectiveness of BNP compared to standard clinical assessment in outpatients with heart failure with reduced ejection fraction (HFrEF) in Tehran, Iran. METHODS: This study was a cost-effectiveness analysis carried on 400 HFrEF outpatients > 45 years who were admitted to Rasoul Akram General Hospital of Tehran, Iran. A Markov model with a lifetime horizon was developed to evaluate economic and clinical outcomes for BNP and standard clinical assessment. Quality-adjusted life-years (QALYs), direct, and indirect costs collected from the patients. RESULTS: The results of this study indicated that mean QALYs and cost were estimated to be 2.18 QALYs and $1835 for BNP and 2.07 and $2376 for standard clinical assessment, respectively. In terms of reducing costs and increasing QALYs, BNP was dominant compared to standard clinical assessment. Also, BNP had an 85% probability of being cost-effective versus standard clinical assessment if the willingness to pay threshold is higher than $20,800/QALY gained. CONCLUSION: Based on the results of the present study, measuring BNP levels represents good value for money, decreasing costs and increasing QALYs compared to standard clinical assessment. It is suggested that the costs of the BNP test be covered by insurance in Iran. The result of the current study has important implications for policymakers in developing clinical guidelines for the diagnosis of heart failure.

Cost-Effectiveness of Multifactorial Interventions in Preventing Falls among Elderly Population: A Systematic Review.

OBJECTIVE: To review the cost-effectiveness of multifactorial interventions to prevent falls in elderly people. METHODS: In this systematic review, the databases including PubMed via MEDLINE, Web of Science, Embase, Scopus, Cochrane Library and Google Scholar (from 1st January 2000 to 30th February) were used. All pre-reviewed articles related to cost-effectiveness analysis of multifactorial interventions to prevent falls in elderly were included in this paper and congresses abstracts were excluded. Descriptive statistics were used for quantitative data and content-analysis method to analyze qualitative data. RESULTS: Out of the 456 articles, 19 were finally included in the study. Eighteen articles were conducted in High-Income Countries (HICs) and 16 were at the community level. Medical visits consultation and education were the most common interventions. Most studies were cost-effectiveness and using the Randomized Control Trial (RCT) methods. A fall of prevention costs ranged from $ 272 to $ 987. Incremental Cost-Effectiveness Ratio (ICER) interventions also ranged from the US $ 120,667 to the US $ 4280.9. CONCLUSION: The results show that despite the high effectiveness of multifactorial interventions to prevent elderly falls, the cost of the interventions are high and they are not very cost-effective. It would be better to design and implement multifactorial interventions with low cost and high effectiveness that are appropriate for each country.

Burden of Transport-Related Injuries in the Eastern Mediterranean Region: A Systematic Analysis for the Global Burden of Disease Study 2017.

BACKGROUND: Transport-related injuries (TIs) are a substantial public health concern for all regions of the world. The present study quantified the burden of TIs and deaths in the Eastern Mediterranean region (EMR) in 2017 by sex and age. METHODS: TIs and deaths were estimated by age, sex, country, and year using Cause of Death Ensemble modelling (CODEm) and DisMod-MR 2.1. Disability-adjusted life years (DALYs), which quantify the total burden of years lost due to premature death or disability, were also estimated per 100000 population. All estimates were reported along with their corresponding 95% uncertainty intervals (UIs). RESULTS: In 2017, there were 5.5 million (UI 4.9-6.2) transport-related incident cases in the EMR - a substantial increase from 1990 (2.8 million; UI 2.5-3.1). The age-standardized incidence rate for the EMR in 2017 was 787 (UI 705.5-876.2) per 100000, which has not changed significantly since 1990 (-0.9%; UI -4.7 to 3). These rates differed remarkably between countries, such that Oman (1303.9; UI 1167.3-1441.5) and Palestine (486.5; UI 434.5-545.9) had the highest and lowest age-standardized incidence rates per 100000, respectively. In 2017, there were 185.3 thousand (UI 170.8-200.6) transport-related fatalities in the EMR - a substantial increase since 1990 (140.4 thousand; UI 118.7-156.9). The age-standardized death rate for the EMR in 2017 was 29.5 (UI 27.1-31.9) per 100000, which was 30.5% lower than that found in 1990 (42.5; UI 36.8-47.3). In 2017, Somalia (54; UI 30-77.4) and Lebanon (7.1; UI 4.8-8.6) had the highest and lowest age-standardized death rates per 100,000, respectively. The age-standardised DALY rate for the EMR in 2017 was 1,528.8 (UI 1412.5-1651.3) per 100000, which was 34.4% lower than that found in 1990 (2,331.3; UI 1,993.1-2,589.9). In 2017, the highest DALY rate was found in Pakistan (3454121; UI 2297890- 4342908) and the lowest was found in Bahrain (8616; UI 7670-9751). CONCLUSION: The present study shows that while road traffic has become relatively safer (measured by deaths and DALYs per 100000 population), the number of transport-related fatalities in the EMR is growing and needs to be addressed urgently.

Predicting the environmental suitability for onchocerciasis in Africa as an aid to elimination planning.

Recent evidence suggests that, in some foci, elimination of onchocerciasis from Africa may be feasible with mass drug administration (MDA) of ivermectin. To achieve continental elimination of transmission, mapping surveys will need to be conducted across all implementation units (IUs) for which endemicity status is currently unknown. Using boosted regression tree models with optimised hyperparameter selection, we estimated environmental suitability for onchocerciasis at the 5 × 5-km resolution across Africa. In order to classify IUs that include locations that are environmentally suitable, we used receiver operating characteristic (ROC) analysis to identify an optimal threshold for suitability concordant with locations where onchocerciasis has been previously detected. This threshold value was then used to classify IUs (more suitable or less suitable) based on the location within the IU with the largest mean prediction. Mean estimates of environmental suitability suggest large areas across West and Central Africa, as well as focal areas of East Africa, are suitable for onchocerciasis transmission, consistent with the presence of current control and elimination of transmission efforts. The ROC analysis identified a mean environmental suitability index of 0·71 as a threshold to classify based on the location with the largest mean prediction within the IU. Of the IUs considered for mapping surveys, 50·2% exceed this threshold for suitability in at least one 5 × 5-km location. The formidable scale of data collection required to map onchocerciasis endemicity across the African continent presents an opportunity to use spatial data to identify areas likely to be suitable for onchocerciasis transmission. National onchocerciasis elimination programmes may wish to consider prioritising these IUs for mapping surveys as human resources, laboratory capacity, and programmatic schedules may constrain survey implementation, and possibly delaying MDA initiation in areas that would ultimately qualify.

Elderly's food security and its associated socioeconomic determinants in Tehran: A cross-sectional study.

INTRODUCTION: The mechanism by which a suppressed immune system of a cancer patient makes them susceptible to COVID-19 is still unclear. Any delay or discontinuation of cancer care due to the pandemic is expected to have a detrimental impact on the outcome of cancer. A few studies have addressed the incidence of COVID-19 among cancer patients, but the small sample size of such studies makes it difficult to draw inference to the general population. METHODS: For our review, 'Pubmed' database and Google search engines were used for searching the relevant articles. The criterion used for review includes their relevance to the defined review question, which is the pathophysiological mechanism of COVID-19 among cancer patients and the relevant therapeutic interventions therewith. This review includes 20 studies and other relevant literature which address the determinants of COVID-19 among Cancer patients. RESULTS: Delay in cancer diagnosis will increase the stage progression of cancer patients and increased mortality in the future. A short delay in administering cancer related treatment to aid the odds of patient surviving the acute SARS-CoV-2 infection, should be at the discretion of the treating Physician. Oncologists dilemma in the current situation includes titrating the density of drug doses and intensity of treatment regimen, for the optimal management of metastatic and adjuvant cancer patients. Patients are thus subjected to suboptimal treatment and undetected disease recurrence, To circumvent the immunosuppressive effects of chemotherapy, Providers need to consider staggered regimen or alternate therapies such as biological/immunotherapy, targeted therapy, anti-angiogenic drugs, hormone therapy and/or antibody-based therapeutics. CONCLUSION: This review provides insights on the pathogenesis of SARS-CoV-2, which could enable Physicians in formulating therapeutic strategies for the management of severe patients, more so in Oncology settings, thus reducing the mortality. The key is to balance the continuation of urgent cancer care, but rationing the elective treatment according to the circumstances.
