Savoring Versus Dampening: Self-Esteem Differences in Regulating Positive Affect.

Five studies examined the hypotheses that when people experience positive affect, those low in self-esteem are especially likely to dampen that affect, whereas those high in self-esteem are especially likely to savor it. Undergraduate participants' memories for a positive event (Study 1) and their reported reactions to a success (Study 2) supported the dampening prediction. Results also suggest that dampening was associated with worse mood the day after a success (Study 2), that positive and negative affect regulation are distinct, that self-esteem is associated with affect regulation even when Neuroticism and Extraversion are controlled (Studies 3 and 4), and that self-esteem may be especially important for certain types of positive events and positive affect regulation (Study 5).

"Snatching defeat from the jaws of victory: Self-esteem differences in the experience and anticipation of success": Correction to Wood et al (2005).

Reports an error in "Snatching Defeat From the Jaws of Victory: Self-Esteem Differences in the Experience and Anticipation of Success" by Joanne V. Wood, Sara A. Heimpel, Ian R. Newby-Clark and Michael Ross (Journal of Personality and Social Psychology, 2005[Nov], Vol 89[5], 764-780). There are typographical errors in Table 2 (certain values should not have been in bold face). The corrected table is provided in the erratum. (The following abstract of the original article appeared in record 2005-15658-009.) Successes--defined broadly as meeting important standards or receiving positive evaluations--are widely assumed to be enjoyed equally by people with high self-esteem (HSEs) and low self-esteem (LSEs). Three studies examined the contradictory hypothesis that HSEs react more favorably to success than do LSEs and that success brings about certain unfavorable consequences for LSEs. Undergraduate participants reacted to a laboratory-manipulated success (Studies 1 and 2) or imagined highly positive events in the future (Study 3). Self-esteem differences emerged in anxiety, thoughts about the self, and (in Study 3) thoughts about non-self-related aspects of the event. LSEs were more anxious than HSEs after succeeding, success improved HSEs' self-relevant thoughts but not LSEs', and LSEs focused more on success's negative aspects.

Long-term interleukin-3 and intensive immunosuppression in the treatment of aplastic anemia

We have assessed in a phase I/II clinical study the tolerability and efficacy of long-term application of recombinant human interleukin-3 (rh-IL-3) in combination with antithymocyte globulin (ATG) and cyclosporin A (CSA) in 13 patients with aplastic anemia who were refractory to or relapsed after previous immunosuppressive treatment. Four cohorts of three patients were consecutively enrolled so that they received rh-IL-3 on days 9, 6, 3 and 1 after start of ATG/CSA treatment. Yeast-derived recombinant human IL-3 was administered by daily subcutaneous injection until day 90 at a dosage of 250 micrograms/m2. Long-term application of rh-IL-3 was well tolerated. The combination of rh-IL-3 with immunosuppression did not modify the known toxicities of ATG and CSA. Incidence and severity of rh-IL-3-related adverse events was less than in other phase I/II trials of rh-IL-3 as single-agent therapy. One might speculate that co-medication with CSA alleviates rh-IL-3-induced side effects. Three of eight patients with refractory AA and all four patients with relapsed AA responded to the combined treatment within four months. The median time to response was 91.5 days. There was evidence for an rh-IL-3-dependent response in two patients. Long-term rh-IL-3 did not cause stem cell exhaustion. One patient died early during the course of the study from EBV-driven lymphoproliferative disease. Two patients developed acute myeloid leukemia 4 and 22 months after cessation of rh-IL-3. In conclusion, long-term rh-IL-3 in combination with immunosuppression is well tolerated. The response rate to the combined treatment in refractory and relapsed AA was high. Recombinant human IL-3-dependent responses suggest efficacy. A prospective randomized trial comparing immunosuppression alone versus a combination with rh-IL-3 is warranted.     

The present state of pathophysiology and therapeutic trials in polycythemia vera

Polycythemia vera shares basic features of pathogenesis with other subtypes of the group of chronic myeloproliferative disorders. All myelopoietic cells are derived from one transformed hemopoietic stem cell. Genetic instability of mitotic clonal cells explains the risk of leukemic transformation, which may be enhanced by cytoreductive treatment. Recent data show that erythroid hyperplasia is not due to erythropoietin hypersensitivity, but rather to abnormal stimulation by other cytokine growth factors. Treatment as established by clinical trials has almost normalized life expectancy in older patients, but the optimal strategy for subgroups of patients is still unknown. For younger patients, new and potentially curative approaches should be investigated.     

This mood is familiar and I don't deserve to feel better anyway: Mechanisms underlying self-esteem differences in motivation to repair sad moods.

Why are people with low self-esteem (LSE) less motivated than people with high self-esteem (HSE) to improve sad moods? The present research examined whether feelings of personal deservingness contribute to this difference. Four experiments with undergraduate participants involved a sad mood induction, a manipulation of personal deservingness, or both. Results suggested that (a) LSEs feel less deserving of positive outcomes and of positive moods than do HSEs, (b) feelings of personal deservingness can vary with the situation, and be lowered through reminders of social rejection and personal flaws, and (c) feeling relatively undeserving dampens LSEs', but not HSEs', motivation to repair sad moods. These results have implications for the emotion regulation, self-esteem, and social justice literatures. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Usefulness of FDG-PET in diagnosing primary lymphoma of the liver

This case report shows for the first time the usefulness of positron emission tomography (PET) with 2-[18F]-fluoro-2-deoxy-D-glucose (FDG) in the diagnosis of primary non Hodgkin's lymphoma of the liver. Results of FDG-PET, which in contrast to other imaging techniques offers the advantage of screening the whole body, demonstrated a high glycolytic activity of a solitary mass in the liver with central necrosis (loss of glycolytic activity), but no spread of lymphoma to the body. These results were confirmed by ultrasound, computed tomography, magnetic resonance imaging and were biopsy proven. From our findings we conclude that in patients with liver masses with high uptake of FDG, lack of liver dysfunction and absence of signs indicating other malignancies, a primary lymphoma of the liver should be considered as a possible diagnosis.     

Do people with low self-esteem really want to feel better? Self-esteem differences in motivation to repair negative moods.

This research examined the hypothesis that people with low self-esteem (LSE) are less motivated than people with high self-esteem (HSE) to repair their negative moods. In Study 1, participants completed diaries in response to either a success or a failure in their everyday lives. Participants described what they intended to do next and the reasons behind those plans. After failure, fewer LSE than HSE participants expressed a goal to improve their mood. A follow-up investigation (Study 2) suggested that this difference was not due to a self-esteem difference in knowledge of mood repair strategies. In Study 3, after undergoing a negative mood induction, fewer LSE than HSE participants chose to watch a comedy video, even though both groups believed the comedy video would make them happy. Studies 4 and 5 explored possible reasons why LSE people are less motivated than HSE people to repair their negative moods. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
