RESUMO
PURPOSE: Breast cancer is the second leading cause of death from cancer among Canadian females. This study aimed to quantify and assess trends in education and income inequalities in the mortality rate of breast cancer in Canada from 1992 to 2019. METHODS: We constructed a census division-level dataset pooled from the Canadian Vital Death Statistics Database (CVSD), the Canadian Census of the Population (CCP), and the National Household Survey (NHS) to examine trends in education and income inequalities in the mortality rate of breast cancer in Canada over the study period. The age-standardized Concentration index (C) was used to quantify income and education inequalities in breast cancer mortality over time. RESULTS: The national crude mortality rate of breast cancer has decreased in Canada from 1992 to 2019, with Alberta, British Columbia, Manitoba, Ontario, Prince Edward Island, and Quebec having the greatest decreases in mortality rate. The age-standardized C for education and income inequalities were always negative for all the study years, meaning that the mortality rate of breast cancer was higher among less-educated and poorer females. Moreover, the results indicate a growing trend in the concentration of breast cancer mortality among females with lower income and education from 1992 to 2019. CONCLUSION: The increasing concentration of breast cancer mortality among low socioeconomic status females remains a challenge in Canada. Continuous efforts are needed within Canadian healthcare system to improve the prevention and treatment of breast cancer for this population.

BACKGROUND: This study aims to investigate cell-free DNA (cfDNA) methylation of genes involved in some immune system targets as biomarkers of radioresistance in patients with non-metastatic rectal cancer. METHODS: Gene expression (GSE68204, GPL6480, and GSE15781) and DNA methylation profiles (GSE75548 and GSE139404) of rectal cancer patients were obtained from the Gene Expression Omnibus (GEO) database. GEO2R and FunRich software were first used to identify genes with significant expression differences. Enricher softwer was then used to analyze Gene Ontology and detect pathway enrichment of hub genes. Blood samples were then taken from 43 rectal cancer patients. After cfDNA extraction from samples, it was treated with bisulfite and analyzed by methylation-specific PCR. RESULTS: 1088 genes with high and 629 with low expression were identified by GEO2R and FunRich software. A total of five high-expression hub genes, including CDH24, FGF18, CCND1, IFITM1, UBE2V1, and three low-expression hub genes, including CBLN2, VIPR2, and IRF4, were identified from UALCAN and DNMIVD databases. Methylation-specific PCR indicated a significant difference in hub gene methylation between cancerous and non-cancerous individuals. Radiochemotherapy significantly affected hub gene methylation. There was a considerable difference in the methylation rate of hub genes between patients who responded to radiochemotherapy and those who did not. CONCLUSIONS: Evaluating gene methylation patterns might be an appropriate diagnostic tool to predict radiochemotherapy response and develop targeted therapeutic agents.

OBJECTIVES: This study aimed to assess the individual and combined effects of SAE and Met on the expression of genes related to insulin signaling, oxidative stress, hormonal imbalance, insulin resistance, and dyslipidemia in rats with induced PCOS. METHODS: The estrous cycle of 50 adult Wistar female rats was monitored through vaginal smears. Subsequently, the rats were randomly assigned into five groups of 10, including control (receiving 1 ml of carboxymethyl cellulose for 49 days), induction (letrozole at 1 mg/kg/d for 21 days), SAE, Met, and SAE/Met. SAE and Met were orally administered at doses of 400 mg/kg/d and 250 mg/kg/d on day 22 and continued for an additional 28 days. Vaginal smears were analyzed, and gene expression levels of GLUT4, SIRT1, TNF-α, and INSR were evaluated using RT-qPCR. Antioxidant parameters were assessed using detection kits. RESULTS: Treatment with SAE and Met restored a regular estrous cycle pattern in PCOS rats. Furthermore, SAE and Met treatment improved hormonal balance, dyslipidemia, and hyperglycemia in the rats. Administration of SAE and Met significantly elevated levels of antioxidant enzymes SOD and GPx in ovarian tissue (P<0.001). Additionally, mRNA levels of GLUT4, SIRT1, and INSR were significantly increased in ovarian tissue following SAE and Met treatment, while TNF-α gene expression decreased significantly (P<0.0001). CONCLUSION: The findings suggest that SAE and Met aqueous extract exert protective effects on letrozole-induced PCOS in rats by modulating gene expression associated with insulin signaling and oxidative stress.
RESUMO
BACKGROUND: Apple stem grooving virus (ASGV) has a wide host range, notably including apples, pears, prunes and citrus. It is found worldwide. METHOD: In this study, two near complete genomes, and seven coat protein (CP) sequences of Iranian isolates from apple were determined. Sequences added from GenBank provided alignments of 120 genomic sequences (54 of which were recombinant), and 276 coat protein genes (none of them recombinant). RESULT: The non-recombinant genomes gave a well supported phylogeny with isolates from diverse hosts in China forming the base of the phylogeny, and a monophyletic clade of at least seven clusters of isolates from around the world with no host or provenace groupings among them, and all but one including isolates from China. The six regions of the ASGV genome (five in one frame, one - 2 overlapping) gave significantly correlated phylogenies, but individually had less statistical support. The largest cluster of isolates contained those from Iran and had isolates with worldwide provenances, and came from a wide range of mono- and dicotyledonous hosts. Population genetic comparisons of the six regions of the ASGV genome showed that four were under strong negative selection, but two of unknown function were under positive selection. CONCLUSION: ASGV most likely originated and spread in East Asia in one or more of various plant species, but not in Eurasia; the ASGV population of China had the greatest overall nucleotide diversity and largest number of segregating sites.

INTRODUCTION: Breast cancer is the most common cancer among females in Canada. This study examines trends in socioeconomic inequalities in the incidence of breast cancer in Canada over time from 1992 to 2010. METHODS: A census division level dataset was constructed using the Canadian Cancer Registry, Canadian Census of the Population and National Household Survey. A summary measure of the Concentration index (C), which captures inequality across socioeconomic groups, was used to measure income and education inequalities in breast cancer incidence over the 19-year period. RESULTS: The crude breast cancer incidence increased in Canada between 1992 and 2010. Age-standardized C values indicated no income or education inequalities in breast cancer incidence in the years from 1992 to 2004. However, the incidence was significantly concentrated among females in high income and highly educated neighbourhoods almost half the time in the 6 most recent years (2005-2010). The trend analysis indicated an increase in breast cancer incidence among females living in high income and highly educated neighbourhoods. CONCLUSION: Breast cancer incidence in Canada was associated with increased socioeconomic status in some more recent years. Our study findings provide previously unavailable empirical evidence to inform discussions on socioeconomic inequalities in breast incidence.

BACKGROUND: Hospitalized older patients spend most of the waking hours in bed, even if they can walk independently. Excessive bedrest contributes to the development of frailty and worse hospital outcomes. We describe the study protocol for the Breaking Bad Rest Study, a randomized clinical trial aimed to promoting more movement in acute care using a novel device-based approach that could mitigate the impact of too much bedrest on frailty. METHODS: Fifty patients in a geriatric unit will be randomized into an intervention or usual care control group. Both groups will be equipped with an activPAL (a measure of posture) and StepWatch (a measure of step counts) to wear throughout their entire hospital stay to capture their physical activity levels and posture. Frailty will be assessed via a multi-item questionnaire assessing health deficits at admission, weekly for the first month, then monthly thereafter, and at 1-month post-discharge. Secondary measures including geriatric assessments, cognitive function, falls, and hospital re-admissions will be assessed. Mixed models for repeated measures will determine whether daily activity differed between groups, changed over the course of their hospital stay, and impacted frailty levels. DISCUSSION: This randomized clinical trial will add to the evidence base on addressing frailty in older adults in acute care settings through a devices-based movement intervention. The findings of this trial may inform guidelines for limiting time spent sedentary or in bed during a patient's stay in geriatric units, with the intention of scaling up this study model to other acute care sites if successful. TRIAL REGISTRATION: The protocol has been registered at clinicaltrials.gov (identifier: NCT03682523).

Canadian provinces and territories have undertaken varied reforms to how primary care is funded, organized, and delivered, but equity impacts of reforms are unclear. We explore disparities in access to primary care by income, educational attainment, dwelling ownership, immigration, racialization, place of residence (metropolitan/non-metropolitan), and sex/gender, and how these have changed over time, using data from the Canadian Community Health Survey (2007/08 and 2015/16 or 2017/18). We observe disparities by income, educational attainment, dwelling ownership, recent immigration, immigration (regular place of care), racialization (regular place of care), and sex/gender. Disparities are persistent over time or increasing in the case of income and racialization (regular medical provider and consulted with a medical professional). Primary care policy decisions that do not explicitly consider existing inequities may continue to entrench them. Careful study of equity impacts of ongoing policy reforms is needed.

PURPOSE: Colorectal cancer is the third most commonly diagnosed cancer in Canada. This study aimed to measure and examine trends in socioeconomic inequalities in the incidence of colorectal cancer in Canada. METHODS: This study is a time trend ecological study based on Canadian Census Division level data constructed from the Canadian Cancer Registry, Canadian Census of Population, and National Household Survey. We assessed trends in income and education inequalities in colorectal cancer incidence in Canada from 1992 to 2010. The age-standardized Concentration index ([Formula: see text]), which measures inequality across all socioeconomic groups, was used to quantify socioeconomic inequalities in colorectal cancer incidence in Canada. RESULTS: The average crude colorectal cancer incidence was found to be 61.52 per 100,000 population over the study period, with males having a higher incidence rate than females (males: 66.98; females: 56.25 per 100,000 population). The crude incidence increased over time and varied by province. The age-standardized C indicated a higher concentration of colorectal cancer incidence among lower income and less-educated neighborhoods in Canada. Income and education inequalities increased over time among males. CONCLUSION: The concentration of colorectal cancer incidence in low socioeconomic neighborhoods in Canada has implications for primary prevention and screening.

BACKGROUND: Healthcare system and intersectoral public health policies play a crucial role in improving population health and reducing health inequalities. This study aimed to quantify their impact, operationalized as avoidable deaths, on the gap in life expectancy (LE) and lifespan inequality (LI) between Iran and three neighbour countries viz., Turkey, Qatar, and Kuwait in 2015-2016. METHODS: Annual data on population and causes of deaths by age and sex for Iran and three neighbour countries were obtained from the World Health Organization mortality database for the period 2015-2016. A recently developed list by the OECD/Eurostat was used to identify avoidable causes of death (with an upper age limit of 75). The cross-country gaps in LE and LI (measured by standard deviation) were decomposed by age and cause of death using a continuous-change model. RESULTS: Iranian males and females had the second lowest and lowest LE, respectively, compared with their counterparts in the neighbour countries. On the other hand, the highest LIs in both sexes (by 2.3 to 4.5 years in males and 1.1 to 3.3 years in females) were observed in Iran. Avoidable causes contributed substantially to the LE and LI gap in both sexes with injuries and maternal/infant mortality represented the greatest contributions to the disadvantages in Iranian males and females, respectively. CONCLUSIONS: Higher mortality rates in young Iranians led to a double burden of inequality -shorter LE and greater uncertainty at timing of death. Strengthening intersectoral public health policies and healthcare quality targeted at averting premature deaths, especially from injuries among younger people, can mitigate this double burden.

INTRODUCTION: Understanding the elasticities of cigarette smoking demand among the youth could help improve the effectiveness of tobacco control interventions. The objective of this study is to measure the price and income elasticities of cigarette smoking demand among urban Bangladeshi male adolescents and young adults aged 10-24 years. METHOD: Using data from a cross-sectional survey conducted in seven urban districts of Bangladesh, we applied probit and ordinary least square (OLS) models to examine the effect of price and income on smoking participation (decision to smoke) and intensity (number of cigarettes smoked). RESULTS: Our results showed that price was not significantly associated with the decision to smoke, while income was a significant determinant of smoking participation. Both price and income determined the smoking intensity. The positive income elasticity (0.39) indicated that participants with greater access to money were more likely to participate in cigarette smoking and smoked more cigarettes. Negative price elasticity (-0.62) implied that increasing prices could lead to a reduction in smoking intensity among adolescents and young adults in urban Bangladesh. CONCLUSION: The inelastic price demand for cigarette smoking suggests that there is scope for increasing tax on cigarettes without compromising the tax revenue. IMPLICATIONS: This is the first study to investigate price and income elasticities among urban adolescents and young adults in Bangladesh. The study found no evidence that increasing the price of cigarettes discourages smoking participation but did show that increasing the price reduces the intensity of smoking among existing smokers. The results also suggest that economic measures such as taxation that increase the price of cigarettes could be a useful policy tool to limit smoking intensity without compromising government tax revenue.

BACKGROUND: The current study was performed to evaluate the impact of Strawberry crinkle virus (SCV) and Strawberry mottle virus (SMoV) viruses, in single and mixed infections, on the yield and physio-biochemical traits of strawberry plants with different genetic backgrounds. Accordingly, the virus-free plantlets were produced via meristem culture and were then transplanted in a research field in different seasons. METHODS AND RESULTS: The results indicated that genetic background clearly affects the responses of the strawberry plants to the viral infection. In addition, considering the effects of changing environmental factors, different seasons had significant influences on the strawberry responses to the virus infection. The results indicated that the components indicating destructive effects were significantly higher during the summer season. Reverse transcription-polymerase chain reaction using viral specific primers revealed 345 and 461 bp fragments for SCV and SMoV viruses, respectively, where all plants were positive for studied viruses. The comparison between the influence of SCV and SMoV viruses on the host plants indicated that SCV caused more damaging effects on the strawberry fruit yield and physio-biochemical traits. Simultaneous infection with SCV and SMoV severely impacted the strawberry plants compared with the effect of each virus individually. CONCLUSION: It is recommended to keep the temperature of the greenhouses producing strawberry at the cooler levels to prevent the spreading of the aphid-transmitted viruses.

BACKGROUND: Despite the high rate of teenage pregnancy in Nigeria and host of negative medical, social and economic consequences that are associated with the problem, relatively few studies have examined socioeconomic inequality in teenage pregnancy. Understanding the key factors associated with socioeconomic inequality in teenage pregnancy is essential in designing effective policies for teenage pregnancy reduction. This study focuses on measuring inequality and identifying factors explaining socioeconomic inequality in teenage pregnancy in Nigeria. METHODS: This is a cross sectional study using individual recode (data) file from the 2018 Nigeria Demographic Health Survey. The dataset comprises a representative sample of 8,423 women of reproductive age 15 - 19 years in Nigeria. The normalized Concentration index (Cn) was used to determine the magnitude of inequalities in teenage pregnancy. The Cn was decomposed to determine the contribution of explanatory factors to socioeconomic inequalities in teenage pregnancy in Nigeria. RESULTS: The negative value of the Cn (-0.354; 95% confidence interval [CI] = -0.400 to -0.308) suggests that pregnancy is more concentrated among the poor teenagers. The decomposition analysis identified marital status, wealth index of households, exposure to information and communication technology, and religion as the most important predictors contributing to observed concentration of teenage pregnancy in Nigeria. CONCLUSION: There is a need for targeted intervention to reduce teenage pregnancy among low socioeconomic status women in Nigeria. The intervention should break the intergenerational cycle of low socioeconomic status that make teenagers' susceptible to unintended pregnancy. Economic empowerment is recommended, as empowered girls are better prepared to handle reproductive health issues. Moreover, religious bodies, parents and schools should provide counselling, and guidance that will promote positive reproductive and sexual health behaviours to teenagers.

INTRODUCTION: Removal of user fee for vulnerable people reduces the financial barriers associated with healthcare payments, which, in turn, improves health outcomes and promotes health equity. This study sought to provide policy strategies to reduce user fee at the point of service delivery for the poor in Iran. METHODS: This is a qualitative study carried out in 2018. The purposive sampling method was applied, and 33 experts with relevant and valuable experiences and maximum variation to obtain representativeness and rich data were interviewed. Trustworthiness criteria were used to assure the quality of the results. The data were analyzed based on thematic analysis using the MAXQDA10 software. RESULTS: The most important issue regarding financial protection against user fee for the poor in Iran is policy integration and cohesion. Differences in access to financial support for user fee coverage among different groups of the poor have led to inequalities in access and financial protection among the poor. The suggested protection policies against the user fee at the point of service delivery in Iran can be categorized into three main categories: 1) basic health social insurance instruments, 2) free health services to the poor outside of the health insurance system, and 3) complementary insurance mechanisms. CONCLUSION: Implementing a cohesive social assistance policy for all disadvantaged groups is needed to address inequalities in financial protection against user fee payment among the poor in Iran. Reducing user fee through mechanisms such as deductible cap, stop-loss, variable user fee and sliding fee scale can improve financial protection and enhance healthcare utilization among the poor. A user fee exemption is not enough to remove barriers to access to service for the poor, as other costs such as transportation expenditures and informal payments also put financial pressure on them. Therefore, financial support for the poor should be designed in a comprehensive protection package to reduce out-of-pocket payments for healthcare services, and indirect costs associated with healthcare utilization.

Potato virus V (PVV) causes a disease of potato (Solanum tubersosum) in South and Central America, Europe, and the Middle East. We report here the complete genomic sequences of 42 new PVV isolates from the potato's Andean domestication center in Peru and of eight historical or recent isolates from Europe. When the principal open reading frames of these genomic sequences together with those of nine previously published genomic sequences were analyzed, only two from Peru and one from Iran were found to be recombinant. The phylogeny of the 56 nonrecombinant open reading frame sequences showed that the PVV population had two major phylogroups, one of which formed three minor phylogroups (A1 to A3) of isolates, all of which are found only in the Andean region of South America (Peru and Colombia), and the other formed two minor phylogroups, a basal one of Andean isolates (A4) that is paraphyletic to a crown cluster containing all the isolates found outside South America (World). This suggests that PVV originated in the Andean region, with only one minor phylogroup spreading elsewhere in the world. In minor phylogroups A1 and A3, there were two subclades on long branches containing isolates from S. phureja evolving more rapidly than the others, and these interfered with dating calculations. Although no temporal signal was directly detected among the dated nonrecombinant sequences, PVV and potato virus Y (PVY) are from the same potyvirus lineage and are ecologically similar, so "subtree dating" was done via a single maximum likelihood phylogeny of PVV and PVY sequences, and PVY's well-supported 157 ce "time to most common recent ancestor" was extrapolated to date that of PVV as 29 bce. Thus the independent historical coincidences supporting the datings of the PVV and PVY phylogenies are the same; PVV arose ≥2,000 years ago in the Andes and was taken to Europe during the Columbian Exchange, where it diversified around 1853 ce, soon after the European potato late blight pandemic. PVV is likely to be more widespread than currently realized and is of biosecurity relevance for world regions that have not yet recorded its presence.[Formula: see text] Copyright © 2022 The Author(s).

INTRODUCTION: Understanding the effects of socioeconomic status on cancer incidence and their trends over time will help inform public health interventions for cancer control. This study sought to investigate trends in socioeconomic inequalities in prostate cancer incidence among Canadian males. METHODS: Using a census division level dataset (n = 280) constructed from the Canadian Cancer Registry, Canadian Census of Population (1992, 1996, 2001, 2006) and 2011 National Household Survey, we examined the effect of socioeconomic status on prostate cancer incidence among Canadian males between 1992 and 2010. The age-adjusted concentration index was used to quantify education/income-related inequalities in prostate cancer incidence. RESULTS: The crude prostate cancer incidence increased from 115 to 137 per 100 000 males in Canada from 1992 to 2010 with a peak in 2007. The rate increased significantly in all but three of four western provinces. The age-adjusted concentration index showed a higher concentration of prostate cancer diagnoses among males living in high-income neighbourhoods in Canada in particular from 1996 to 2005. In contrast, the index was higher among males living in less-educated neighbourhoods in the most recent study years (2006-2010). CONCLUSIONS: The concentration of new prostate cancer cases among high-income populations in Canada may be explained by the rise of opportunistic screening of asymptomatic males; however, this should be studied in further detail. Since we found a higher incidence rate of prostate cancer among less-educated males in Canada in recent years, risk-benefit investigation of primary prevention and opportunistic screening for less-educated males is advised.

BACKGROUND: Although malaria in pregnancy is preventable with the use of intermittent preventive treatment with sulfadoxine-pyrimethamine (IPTp-SP), it still causes maternal morbidity and mortality, in sub-Saharan Africa and Nigeria in particular. Socioeconomic inequality leads to limited uptake of IPTp-SP by pregnant women and is, therefore, a public health challenge in Nigeria. This study aimed to measure and identify factors explaining socioeconomic inequality in the uptake of IPTp-SP in Nigeria. METHODS: The study re-analysed dataset of 12,294 women aged 15-49 years from 2018 Nigeria Demographic Health Survey (DHS). The normalized concentration index (Cn) and concentration curve were used to quantify and graphically present socioeconomic inequalities in the uptake of IPTp-SP among pregnant women in Nigeria. The Cn was decomposed to identify key factors contributing to the observed socioeconomic inequality in the uptake of adequate (≥ 3) IPTp-SP. RESULTS: The study showed a higher concentration of the adequate uptake of IPTp-SP among socioeconomically advantaged women (Cn = 0.062; 95% confidence interval [CI] 0.048 to 0.076) in Nigeria. There is a pro-rich inequality in the uptake of IPTp-SP in urban areas (Cn = 0.283; 95%CI 0.279 to 0.288). In contrast, a pro-poor inequality in the uptake of IPTp-SP was observed in rural areas (Cn = - 0.238; 95%CI - 0.242 to - 0.235). The result of the decomposition analysis indicated that geographic zone of residence and antenatal visits were the two main drivers for the concentration of the uptake of IPTp-SP among wealthier pregnant women in Nigeria. CONCLUSION: The pro-rich inequalities in the uptake of IPTp-SP among pregnant women in Nigeria, particularly in urban areas, warrant further attention. Strategies to improve the uptake of IPTp-SP among women residing in socioeconomically disadvantaged geographic zones (North-East and North-West) and improving antenatal visits among the poor women may reduce pro-rich inequality in the uptake of IPTp-SP among pregnant women in Nigeria.

BACKGROUND: Strawberry crinkle virus (SCV) is a member of the genus Cytorhabdovirus, family Rhabdovirida, and order Mononegavirales. SCV affects the production of various strawberry cultivars. In this study we investigated the genetic diversity of SCV in strawberry fields based on P3 (movement protein) gene. METHODS AND RESULTS: The samples were collected from strawberry fields in the Kurdistan Province, Iran. P3 gene from 20 SCV isolates, representing 18 nucleic acid haplotypes, is composed of 729 nucleotides, encoding a protein with 243 amino acids. SCV-P3 sequences shared 98.77%-99.86% nucleotide and 97.5%-100% amino acid sequence identity. Phylogenetic analyses of the new P3 sequences with two previously published SCV-P3 sequences from the Czech Republic showed that there are two major phylogroups (I and II) and three minor phylogroups in the body of the phylogeny, I-1, I-2, II-1. Comparisons of P3 gene sequences revealed a mutational bias, with more differences being transitions than transversions. The ratio of non-synonymous/synonymous nucleotide changes was < 1, indicating that SCV-P3 gene is under predominantly negative selection. CONCLUSIONS: Phylogenetic and sequence identity analyses showed that SCV isolates from Iran are closely related and have not diverged more than 2% based on P3 gene despite geographical separation and strawberry cultivar. This is the first report of the genetic diversity of SCV worldwide.

BACKGROUND: There is evidence of socioeconomic inequalities in cancer incidence in Canada and other countries globally, yet there is no study investigating socioeconomic inequalities in national cervical cancer incidence in Canada. Thus, the current study investigated income and education inequalities in the incidence of cervical cancer in Canada from 1992 to 2010. METHODS: Data were derived from a linked dataset that combined cervical cancer incidence from the Canadian Cancer Registry and demographic and socioeconomic information from the Canadian Census of Population and the National Household Survey. The Concentration index approach was used to measure income and education inequalities in the incidence of cervical cancer over time. RESULTS: National incidence of cervical cancer decreased significantly from 1992 to 2010. The age-standardized C was negative for the majority of years for both income and education inequalities, but the preponderance were not significant. Trend analyses of socioeconomic inequalities suggested an increasing concentration of cervical cancer incidence among less-educated females over the study period. CONCLUSIONS: Over almost two decades, there were no pervasive socioeconomic inequalities in the incidence of cervical cancer in Canada. As such, policies aimed at reducing the incidence of cervical cancer should focus on the general population, irrespective of socioeconomic status.

BACKGROUND: Understanding patient preferences in emergency departments (EDs) can provide useful information to enhance patient-centred care and improve patient's experience in hospitals. This study sought to find evidence about patients' preference for physicians when receiving services in EDs in Iran. METHODS: In this discrete choice experiment survey, 811 respondents completed the scenarios with 5 attributes, including type of physicians, price of services, time to receive services, physician work experience, and physician responsibility. Analyses were conducted for different social and economic groups as well as for the total population. RESULTS: This study showed that the willingness to pay (WTP) for being visited by a physician with a high sense of responsibility was 67.104US$. WTP for being visited by an emergency medicine specialist (EMS) was 22.148US$. WTP for receiving ED services 1 min earlier was 0.417US$ and for being visited by 1 year higher experienced physician was 0.866US$. WTP varied across different age groups, sex, health status, education, and income groups. CONCLUSION: As the expertise and experience of providers are important factors in selecting physicians in EDs by the patients, providing this information to patients when they want to select their providers can promote patient-centred care. This information can decrease patients' uncertainty in the selection of their services and improve their experience in hospitals.

Ovarian cancer is the seventh most common cancer among women worldwide. We assessed the effect of socioeconomic status on ovarian cancer incidence in Canada between 1992 and 2010. We linked data from the Canadian Cancer Registry (CCR), Canadian Census of Population (CCP), and National Household Survey (NHS) to measure socioeconomic inequalities in the incidence of ovarian cancer among Canadian women over the study period. The age-standardized relative and absolute concentration index (RC and AC, respectively) were calculated to quantify income- and education-related inequalities in the incidence of ovarian cancer in Canadian women during this period. Despite a slight increase in the crude incidence of ovarian cancer in Ontario, Quebec, New Brunswick, Newfoundland and Labrador & Prince Edward Island, and Canada as a whole, the incidence of ovarian cancer in Canada has mostly remained stable, between 13 and 15 new cases per 100,000 per year between 1992 and 2010. The estimated age-standardized RC and AC values for the study period did not indicate any statistically significant relationship between income or education status, and the incidence of ovarian cancer in Canada. Future work should be directed at seeking related risk factors other than socioeconomic status that may contribute to the incidence of this disease.
