Relative Energy Balance, CKD, and Risk of Cardiovascular and All-Cause Mortality.

BACKGROUND Mortality risk for people with chronic kidney disease is substantially greater than that for the general population, increasing to a 7-fold greater risk for those on dialysis therapy. Higher body mass index, generally due to higher energy intake, appears protective for people on dialysis therapy, but the relationship between energy intake and survival in those with reduced kidney function is unknown. STUDY DESIGN Prospective cohort study with a median follow-up of 14.5 (IQR, 11.2-15.2) years. SETTING & PARTICIPANTS Blue Mountains Area, west of Sydney, Australia. Participants in the general community enrolled in the Blue Mountains Eye Study (n=2,664) who underwent a detailed interview, food frequency questionnaire, and physical examination including body weight, height, blood pressure, and laboratory tests. PREDICTORS Relative energy intake, food components (carbohydrates, total sugars, fat, protein, and water), and estimated glomerular filtration rate (eGFR). Relative energy intake was dichotomized at 100%, and eGFR, at 60mL/min/1.73m(2). OUTCOMES All-cause and cardiovascular mortality. MEASUREMENTS All-cause and cardiovascular mortality using unadjusted and adjusted Cox proportional regression models. RESULTS 949 people died during follow-up, 318 of cardiovascular events. In people with eGFR<60mL/min/1.73m(2) (n=852), there was an increased risk of all-cause mortality (HR, 1.48; P=0.03), but no increased risk of cardiovascular mortality (HR, 1.59; P=0.1) among those with higher relative energy intake compared with those with lower relative energy intake. Increasing intake of carbohydrates (HR per 100g/d, 1.50; P=0.04) and total sugars (HR per 100g/d, 1.62; P=0.03) was associated significantly with increased risk of cardiovascular mortality. LIMITATIONS Under-reporting of energy intake, baseline laboratory and food intake values only, white population. CONCLUSIONS Increasing relative energy intake was associated with increased all-cause mortality in patients with eGFR<60mL/min/1.73m(2). This effect may be mediated by increasing total sugars intake on subsequent cardiovascular events.

Balance theory in eWOM: Even if you red-flag this product, I like it, as I dislike you

In eWOM the relationship between the consumer and the reviewer is weak. Still, the present study argues that social information, for example the reviewer`s user picture, influences the product evaluation. By applying balance theory we predict that the evaluation of the recommended product is a function of the induced attitude towards the reviewer and the valence of the review. By utilizing either positive or negative user pictures and either positive or negative reviews, we confirmed the hypothesized interaction. Consumers rated a negatively reviewed product more favorable when the reviewer used a negative user picture, compared to a positive user picture.

Restoring balance within cognitive unit or deservingness evaluation? The role of attitudes and deservingness in shaping emotional reactions to others’ outcomes

Based on Heider’s theory I persumed that personal attitudes are stronger predictors of emotional responses to others’ outcomes than deservingness evaluation. I manipulated outcome, attitude and deservingness experimentally, and measured specific emotions. It appeared deservingness to play a secondary role in eliciting joy and sorrow when interpersonal attitudes were involved.

Joy, Schadenfreude, Sorrow, and Resentment as Responses Restoring Balance in Cognitive Units

Based on Heider’s (1958) balance theory we hypothesize that emotional responses to other persons’ outcomes depend on attitudes towards these persons. Positive attitudes towards others lead to empathic responses to their outcomes– joy after a success and sorrow after a failure. Negative attitudes result in paradoxical responses – negative to a success (resentment) and positive to a failure (schadenfreude). These emotions function as responses restoring balance within cognitive units consisting of the perceiver, other persons and their outcomes. Three studies supported these hypotheses and showed that deservingness considerations play a weaker role in shaping emotional responses of joy and sorrow to others’ outcomes when strong interpersonal attitudes are involved. However, deservingness plays an independent role in shaping the emotional response of resentment.
