Deciding who should receive maximal technological treatment options and who should not represents an ethical, moral, psychological
and medico-legal challenge for health care providers. Especially in patients with chronic heart failure, the ethical and medico-legal
issues associated with providing maximal possible care or withholding the same are coming to the forefront. Procedures, such
as cardiac transplantation, have strict criteria for adequate candidacy. These criteria for subsequent listing are based on
clinical outcome data but also reflect the reality of organ shortage. Lack of compliance and non-adherence to lifestyle changes
represent relative contraindications to heart transplant candidacy. Mechanical circulatory support therapy using ventricular
assist devices is becoming a more prominent therapeutic option for patients with end-stage heart failure who are not candidates
for transplantation, which also requires strict criteria to enable beneficial outcome for the patient. Physicians need to
critically reflect that in many cases, the patient’s best interest might not always mean pursuing maximal technological options
available. This article reflects on the multitude of critical issues that health care providers have to face while caring
for patients with end-stage heart failure. 相似文献

Mediation analysis uses measures of hypothesized mediating variables to test theory for how a treatment achieves effects on outcomes and to improve subsequent treatments by identifying the most efficient treatment components. Most current mediation analysis methods rely on untested distributional and functional form assumptions for valid conclusions, especially regarding the relation between the mediator and outcome variables. Propensity score methods offer an alternative whereby the propensity score is used to compare individuals in the treatment and control groups who would have had the same value of the mediator had they been assigned to the same treatment condition. This article describes the use of propensity score weighting for mediation with a focus on explicating the underlying assumptions. Propensity scores have the potential to offer an alternative estimation procedure for mediation analysis with alternative assumptions from those of standard mediation analysis. The methods are illustrated investigating the mediational effects of an intervention to improve sense of mastery to reduce depression using data from the Job Search Intervention Study (JOBS II). We find significant treatment effects for those individuals who would have improved sense of mastery when in the treatment condition but no effects for those who would not have improved sense of mastery under treatment. 相似文献

The interaction between redundant geometric and featural cues in open field search tasks has been examined widely with results that are not always consistent. Cheng (1986) found evidence that when searching for food in rectangular environments, rats used the geometrical characteristics of the environment rather than local featural cues, suggesting that geometry had overshadowed featural cues. More recently, Graham et al. (2006) and Pearce et al. (2006) found that wall color facilitated (potentiated) learning about the shape of the environment by rats in a kite-shaped water maze. The first experiment in the present research replicated the paradigm used by Graham et al. and Pearce et al. using rats in a foraging situation, but with conditions similar, and found the same results, potentiation of shape by color. Experiments 2 and 3 revealed overshadowing instead of potentiation of shape by wall color under the same conditions except that the wall colors of the test environment were not the same as those used during training. The results are consistent with an analysis of the role of associations formed between wall color and geometry in such situations (Rhodes et al., 2009) and extend our understanding of how featural and spatial cues interact. 相似文献

Power and organizational hierarchies are ubiquitous to social institutions that form the foundation of modern society. Power differentials may act to constrain or enhance people’s ability to make good ethical decisions. However, little scholarly work has examined perceptions of this important topic. The present effort seeks to address this issue by interviewing academics about hypothetical ethical problems that involve power differences among those involved. Academics discussed what they would do in these scenarios, often drawing on their own experiences. Using a think-aloud protocol, participants were prompted to discuss their reasoning and thinking behind their ethical decisions. These interview data were content analyzed using a semantic analysis program that identified a number of distinct ways that academics think about power differences and abuses in ethical situations. Implications of these findings are discussed. 相似文献

Infant social withdrawal is a risk factor for non-optimal child development; thus, it is important to identify risk factors associated with withdrawal. In a large community sample (N = 19,017), we investigate whether symptoms of maternal and partner postpartum depression (PPD; measured with the Edinburgh Postnatal Depression Scale) and prematurity are predictors of infant social withdrawal (measured with the Alarm Distress Baby Scale). Withdrawal was assessed at 2–3, 4–7 and 8–12 months postpartum. Linear regressions showed that prematurity predicted higher infant social withdrawal at all time points, and maternal symptoms of PPD were positively associated with withdrawal at 2–3 months. Logistic regressions showed that odds for elevated social withdrawal were increased with elevated levels of maternal symptoms of PPD at 2–3 and 8–12 months. Partner's symptoms of PPD were not associated with withdrawal. Future studies should investigate how PPD symptoms and prematurity may impact the individual development of social withdrawal. 相似文献

Four studies were conducted with two primary objectives: (a) to conceptualize and measure mental toughness from a behavioral perspective and (b) to apply relevant personality theory to the examination of between‐person differences in mentally tough behavior. Studies 1 (N = 305 participants from a range of different sports) and 2 (N = 110 high‐level cricketers) focused on the development of an informant‐rated mental toughness questionnaire that assessed individual differences in ability to maintain or enhance performance under pressure from a wide range of stressors. Studies 3 (N = 214) and 4 (N = 196) examined the relationship between reinforcement sensitivities and mentally tough behavior in high‐level cricketers. The highest levels of mental toughness reported by coaches occurred when cricketers were sensitive to punishment and insensitive to reward. Study 4 suggested that such players are predisposed to identify threatening stimuli early, which gives them the best possible opportunity to prepare an effective response to the pressurized environments they encounter. The findings show that high‐level cricketers who are punishment sensitive, but not reward sensitive, detect threat early and can maintain goal‐directed behavior under pressure from a range of different stressors. 相似文献

This study examined associations between elevated symptoms of prenatal depression or anxiety and offspring emotional and behavioral problems during mid to late childhood taking into account the impact of later maternal mental health symptoms. The sample consisted of 2,891 women and their children (49 % male) from a prospective, community-based study, the Avon Longitudinal Study of Parents and Children. Women completed measures of depressive (Edinburgh Postnatal Depression Scale) and anxious (Crown Crisp Experiential Index) symptoms at regular intervals beginning in pregnancy. Mothers and teachers assessed offspring emotional and behavioral problems using the Strengths and Difficulties Questionnaire when children were 10–11 years old. Multivariable regression models were fit to address study hypotheses. Exposure to elevated symptoms of maternal depression during pregnancy was associated with increased total offspring emotional and behavioral problems, even after controlling for later maternal mental health problems and a range of sociodemographic and psychosocial characteristics, according to mothers’ but not teachers’ reports. Similarly, children exposed to elevated symptoms of maternal anxiety during pregnancy were reported to have increased total emotional and behavioral problems by mothers but not by teachers. We found support for modest associations between elevated symptoms of maternal depression and anxiety during the prenatal period and certain domains of offspring emotional and behavioral problems in mid to late childhood above and beyond the impact of later maternal mental health problems. These findings highlight the need for additional clinical and research attention to the prenatal period and to both maternal depression and anxiety. 相似文献

Absolute linguistic universals are often justified by cross‐linguistic analysis: If all observed languages exhibit a property, the property is taken to be a likely universal, perhaps specified in the cognitive or linguistic systems of language learners and users. In many cases, these patterns are then taken to motivate linguistic theory. Here, we show that cross‐linguistic analysis will very rarely be able to statistically justify absolute, inviolable patterns in language. We formalize two statistical methods—frequentist and Bayesian—and show that in both it is possible to find strict linguistic universals, but that the numbers of independent languages necessary to do so is generally unachievable. This suggests that methods other than typological statistics are necessary to establish absolute properties of human language, and thus that many of the purported universals in linguistics have not received sufficient empirical justification. 相似文献
