Background Osteoporosis is a skeletal disease that is associated with a reduction in bone mass and microstructures and deterioration of bone tissue. It is also associated with an increased risk of fracture that is the most important complication of osteoporosis. Osteoporosis and consequent fractures not only have a major impact on the health and quality of life, but also impose a significant economic burden on the health system of countries. Objective Since the population of many countries around the world is aging, the incidence of fractures due to osteoporosis is increasing too. The knowledge about costs and economic aspects of osteoporosis plays an important role in making policies and planning measures for the prevention and management of this disease, hence, this study systematically investigated the available evidence on the costs associated with osteoporosis worldwide. Methods Considering language, year of publication, and the research question, electronic searches were conducted in multiple databases and different sources. After selecting articles based on inclusion and exclusion criteria, the data were extracted and the results were summarized. To prevent bias, the whole procedure was performed by three researchers. Results Of a total of 1989 papers, 28 papers were included in the study on the basis of inclusion criteria. Among the selected studies, 13 papers reported direct and indirect costs. Based on the data extracted from the mentioned studies, the mean age of people with osteoporotic fractures was 50 years, with the highest costs associated with hip fractures. Conclusion There is a paucity of studies investigating the burden of osteoporosis in the world. The available studies indicate a lack of standardization in the methodological approach of assessing the economic burden of this disease. It is necessary to highlight the importance of studies on osteoporosis to inform policymakers and enhance health care planning.
Background
This study aimed to review studies on willingness to pay (WTP) for prostate cancer screening.
Methods
This systematic-review was conducted based on the Preferred Reporting Items for Systematic Reviews guidelines. By searching six-health-database, WTP studies on prostate cancer screening using contingent valuation method published in English until March 2020 were included and those with unavailable full-text and inadequate quality-assessment scores were excluded. Smith checklist was used for the quality assessment. Extracted WTPs were converted to US dollar in 2018 using exchange rate parity and net present value formula to make comparison. Factors’ effect was assessed by vote counting.
Results
Six final studies published after 2006 reported above 70% Smith checklist items needed to be considered in contingent valuation study reports. Seven factors have positive effects on WTP. The reported WTP value varied from 11$ to 588$ in Japan and Germany, respectively.
Conclusion
WTP for prostate cancer screening was positive among all studied men. The results of factors’ effect assessment showed that better understanding prostate cancer risks or screening tests and factors such as age, income, family history of cancer, hospitalization history, and educational level have positive effects. Moreover, prostate-specific antigen history, health insurance, employment, and subject’s health assessment received less attention.
The results’ generalization to all countries is not applicable because there are no studies for low- and middle-income countries.

Palliative care is specialized medical care for people living with a serious illness. This type of care is focused on providing relief from the symptoms and stress of the illness. The goal is to improve the quality of life for both the patient and the family.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
