Rabin's paradox for health outcomes.

ABSTRACT: Many health economic studies assume expected utility maximisation, with typically a concave utility function to capture risk aversion. Given these assumptions, Rabin's paradox (RP) involves preferences over mixed gambles yielding moderate outcomes, where turning down such gambles imply absurd levels of risk aversion. Although RP is considered a classic critique of expected utility, no paper has as of yet fully tested its preferences within individuals. In an experiment we report a direct test of RP in the health domain, which was previously only considered in the economic literature, showing it may have pervasive implications here too. Our paper supports the shift towards alternative, empirically valid models, such as prospect theory, also in the health domain. These alternative models are able to accommodate Rabin's paradox by allowing reference-dependence and loss aversion.

DREAM, a Possible Answer to the Estrogen Paradox of the Women’s Health Initiative Trial

Project description:Estrogen is thought to cause proliferation of all estrogen receptor positive (ER+) breast cancers. Paradoxically, in the Women’s Health Initiative Trial, estrogen-only hormone replacement therapy reduced the incidence and mortality of low grade, ER+, HER2- breast cancer. We gave estradiol to 19 post-menopausal women with newly diagnosed low-grade, ER+, HER2- breast cancer in a prospective window of opportunity clinical trial and examined the changes in proliferation and gene expression before and after estradiol treatment. Ki67 decreased in 13/19 (68%) patients and 8/13 (62%) showed a decrease in Risk of Recurrence Score. We chose three prototypical estrogen responders (greatest decrease in ROR) and non-responders (no/minimal change in ROR) and applied a differential gene expression analysis to develop pre-treatment (PRESTO-30core) and post-treatment (PRESTO-45surg) gene expression profiles. The PRESTO-30core predicted adjuvant benefit in a published series of tamoxifen, the partial estrogen agonist. Of the 45 genes in the PRESTO-45surg, thirty contain the Cell cycle genes Homology Region (CHR) motif that binds the class B multi-vulva complex (MuvB) a member of the DREAM (Dimerization partner, retinoblastoma-like proteins, E2F, MuvB) complex responsible for reversible cell cycle arrest or quiescence. There was also near uniform suppression (89%) of the remaining DREAM genes consistent with estrogen induced activation of the DREAM complex to mediate cell cycle block after a short course of estrogens. To our knowledge, this is the first report to show hormonal modulation of DREAM genes and suggest involvement of DREAM pathway associated quiescence in endocrine responsive post-menopausal ER+ breast cancers.

Racial and Ethnic Postoperative Outcomes After Surgery: The Hispanic Paradox.

Project description:BACKGROUND:The Hispanic population in the United States have previously been shown to have, in some cases, better health outcomes than non-Hispanic whites (NHWs) despite having lower socioeconomic status and higher frequency of comorbidities. This epidemiologic finding is coined as the Hispanic Paradox (HP). Few studies have evaluated if the HP exists in surgical patients. Our study aimed to examine postoperative complications between Hispanic and NHW patients undergoing low- to high-risk procedures. MATERIALS AND METHODS:We conducted a retrospective cohort study analyzing adult patients who underwent high-, intermediate-, and low-risk procedures. The Healthcare Cost and Utilization Project California State Inpatient Database between 2006 and 2011 was used to identify the patient cohort. Candidate variables for the adjusted model were determined a priori and included patient demographics with the ethnic group as the exposure of interest. RESULTS:The median age for Hispanics was 52 (SD 19.3) y, and 38.8% were male (n = 87,837). A higher proportion of Hispanics had Medicaid insurance (23.9% versus 3.8%) or were self-pay (14.2% versus 4.5%) compared with NHWs. In adjusted analysis, Hispanics had a higher odds risk for postoperative complications across all risk categories combined (OR 1.06, 95% CI 1.04-1.09). They also had an increased in-hospital (OR 1.38, 95% CI 1.14-1.30) and 30-d mortality in high-risk procedures (OR 1.34, 95% CI 1.19-1.51). CONCLUSIONS:Hispanics undergoing low- to high-risk surgery have worse outcomes compared with NHWs. These results do not support the hypothesis of an HP in surgical outcomes.

Evidence of a disability paradox in patient-reported outcomes in haemophilia.

Project description:IntroductionPeople with inherited and long-term conditions such as haemophilia have been shown to adapt to their levels of disability, often reporting better quality of life (QoL) than expected from the general population (the disability paradox).AimTo investigate the disability paradox in people with haemophilia in the United States by examining preference differences in health state valuations versus the general population.MethodsWe conducted a discrete choice experiment including duration to capture valuations of health states based on patient-reported preferences. Participants indicated their preferences for hypothetical health states using the EQ-5D-5L, where each participant completed 15 of the 120 choice tasks. Response inconsistencies were evaluated with dominated and repeated scenarios. Conditional-logit regressions with random sampling of the general population responses were used to match the sample of patients with haemophilia. We compared model estimates and derived preferences associated with EQ-5D-5L health states.ResultsAfter removing respondents with response inconsistencies, 1327/2138 (62%) participants remained (177/283 haemophilia; 1150/1900 general population). Patients with haemophilia indicated higher preference value for 99% of EQ-5D-5L health states compared to the general population (when matched on age and gender). The mean health state valuation difference of 0.17 indicated a meaningful difference compared to a minimal clinically important difference threshold of 0.07. Results were consistent by haemophilia type and severity.ConclusionOur findings indicated the presence of a disability paradox among patients with haemophilia, who reported higher health states than the general population, suggesting the impact of haemophilia may be underestimated if general population value sets are used.

Adipokines and vascular health in treated HIV infection: an obesity paradox?

Project description:We examined the relationship between plasma adipokine concentrations and ultrasound measures of vascular health in 100 HIV-infected adults on antiretroviral therapy. Leptin was positively correlated with flow-mediated dilation of the brachial artery and negatively with carotid intima-media thickness. These relationships were independent of traditional risk factors and trunk fat in women but not men. Neither adiponectin nor resistin was associated with either measure of vascular health.

Intralocus sexual conflict can resolve the male-female health-survival paradox.

Project description:At any given age, men are more likely to die than women, but women have poorer health at older ages. This is referred to as the "male-female, health-survival paradox", which is not fully understood. Here, we provide a general solution to the paradox that relies on intralocus sexual conflict, where alleles segregating in the population have late-acting positive effects on male fitness, but negative effects on female health. Using an evolutionary modelling framework, we show that male-benefit, female-detriment alleles can spread if they are expressed after female reproduction stops. We provide support for our conflict based solution using experimental Drosophila data. Our results show that selecting for increased late-life male reproductive effort can increase male fitness but have a detrimental effect on female fitness. Furthermore, we show that late-life male fertility is negatively genetically correlated with female health. Our study suggests that intralocus sexual conflict could resolve the health-survival paradox.

Health outcomes in SARS survivors 18 years after infection: A longitudinal cohort study

Project description:We aimed to characterize the long-term health outcomes of survivors of severe acute respiratory syndrome (SARS) and determine their recovery status and possible immunological basis. Although health outcomes continued to improve, SARS survivors still suffered from physical fatigue, osteoporosis, and necrosis of the femoral head 18 years after discharge, possibly related to plasma metabolic disorders and immunological alterations.

Saturated fats, dairy foods and cardiovascular health: No longer a curious paradox?

Project description:Cardiovascular diseases (CVDs) are a major cause of death and morbidity in many parts of the world, and many dietary guidelines limit the intake of saturated fatty acids (SFA) as they are regarded as an important risk factor for CVDs due to their association with increased blood cholesterol. Dairy foods are often a major contributor to dietary intake of SFA, and since many dietary guidelines contain restrictions on SFA intake, this can lead to a moderation of dairy food intake despite meta-analyses generally showing dairy to have a neutral or negative association with CVDs. Many prospective studies and randomised controlled trials do not support a simple positive association between SFA intake and the risk of atherosclerotic CVD and its components although some early studies had a number of methodological weakness. Studies that included blood cholesterol data do broadly support the positive relationship between SFA and blood low-density lipoprotein cholesterol (LDL-C) but without increased CVD risk resulting, despite LDL being a causal factor in atherosclerotic CVD. These data suggest that LDL-C alone is not a consistently good predictor or cause of CVD risk, perhaps particularly in relation to dairy food consumption although some non-dairy food studies have also shown LDL-C reduction was not reflected in reduced CVD risk. This narrative review examines some reasons for these findings. Overall, restrictions on dairy food intake do not seem warranted, although there remains a need to further understand the association of different dairy food types with chronic diseases, perhaps particularly for type 2 diabetes.

The wellbeing paradox in Hungarian local sustainable agriculture: a health psychology approach.

Project description:BackgroundThe literature suggests that farmers' work involves a number of operational difficulties. Although alternative food networks address the majority of their problems, they can potentially generate new hardships. The aim of this study is to examine the situational and engagement-related work difficulties associated with the everyday world of Community Supported Agriculture (CSA) farmers.MethodsThis study used the health psychology approach, namely interpretive phenomenology, to understand the social determinants of farmers' working lives in CSA and to explore mental health challenges within the practices of local sustainable farming. To collect data, semi-structured, in-person interviews were conducted with CSA farmers in Hungary.ResultsOur study shows that new modes of consumer-producer connectivity create novel situations and issues which farmers are forced to address. Three personal experiential themes emerge from the data to describe CSA farmers' work difficulties: (1) Conflicted autonomy; (2) The pressure of boxes; (3) Social overload. The difficulties for CSA farmers seem to be rooted in the economic characteristics of alternative agriculture where farmers organize food production for the satisfaction of consumer needs. In addition, structural conditions require several different CSA farmer roles, which could even be conflicting.ConclusionThis study provides participants' perspectives on the health and wellbeing costs of sustainable farming. Newer producer-consumer connections require both time and experience and involve extra effort or skills, but farmers often lack these abilities. The results show how perceptions of work processes relate to the general framework of CSA, which necessitates a distinct strategy for farm management.

Are Distressed Black Women Also Depressed? Implications for a Mental Health Paradox.

Project description:PurposeRecent research suggests the determinants of and links between psychological distress and psychiatric disorder are distinct among Black Americans. Yet, these associations have not been explored among Black women, despite the unique social experiences, risks, and mental health patterns they face. The present study assessed the sociodemographic and psychosocial determinants of distress and disorder and evaluated the distress-disorder association, including whether it was conditional on sociodemographic and psychosocial characteristics among Black women.MethodsData were from 328 Black women in the Nashville Stress and Health Study, a cross-sectional community epidemiologic survey of Blacks and Whites in Nashville, Tennessee, and was used to assess the correlates of distress (CES-D depressive symptoms scale) and major depressive disorder (MDD; based on the CIDI). Multinomial logistic regression models estimated the extent to which greater distress was associated with higher risk of "chronic" or "resolved MDD".ResultsStress exposure and marital status were associated with greater distress, while stress exposure and childhood SES were associated with elevated disorder risk. Although increased distress was associated with greater disorder risk, significant interactions indicated these associations depend on differences in age and adult socioeconomic status within this population.ConclusionsThis study identifies distinct correlates of distress and disorder and shows that the distress-disorder association varies among subgroups of Black women. Results have important implications for public health research and practice, as they highlight the factors that matter most for the mental health outcomes of Black women.
