Work-Related Well-Being Among Dutch Cardiologists - A National Survey.

This is the first study to provide a holistic examination of cardiologists' well-being, investigating positive and negative dimensions, and its determinants. We conducted a national, multicenter, self-administered web-based questionnaire. We used frequencies to depict scores on three well-being indicators (professional fulfillment, work exhaustion and interpersonal disengagement) and performed three multiple regression analyses to elucidate their determinants. Cardiologists' mean scores (scale 1 to 5) were 3.85 (SD = 0.62) for professional fulfillment, 2.25 (SD = 0.97) for work exhaustion and 2.04 (SD = 0.80) for interpersonal disengagement. Workload, work-home interference and team atmosphere predicted the negative dimensions of well-being. Autonomy predicted cardiologists' professional fulfillment. Physician-patient interactions, person-job fit and individual resilience affected both dimensions. Dutch cardiologists score relatively high on professional fulfillment and average on work exhaustion and interpersonal disengagement. In order to foster cardiologists' well-being it is critical to increase energy providing work- and individual aspects.

The Effects of ß-Adrenergic Blockade on the Degrading Effects of Eye Movements on Negative Autobiographical Memories.

BACKGROUND: Eye movement desensitization and reprocessing (EMDR) is an effective treatment for posttraumatic stress disorder. During EMDR, patients make horizontal eye movements (EMs) while simultaneously recalling a traumatic memory, which renders the memory less vivid and emotional when it is later recalled again. Recalling highly emotional autobiographical memories enhances noradrenergic neurotransmission. Noradrenaline (NA) strengthens memory (re)consolidation. However, memories become less vivid after recall+EMs. Therefore, NA might either play no significant role or serve to strengthen memories that are degraded by EMs. The present study was designed to test the latter hypothesis. We predicted that blocking NA would abolish the memory degrading effects of EMs. METHODS: Fifty-six healthy participants selected three negative autobiographical memories. One was then recalled while making EMs, one was recalled without EMs, and one was not recalled. Vividness and emotionality of the memories as well as heart rate and skin conductance level during memory retrieval were measured before, directly after, and 24 hours after the EM task. Before the task, participants received a placebo or the noradrenergic ß-receptor blocker propranolol (40 mg). RESULTS: There were no effects of EMs on memory emotionality or psychophysiological measures in the propranolol and placebo groups. However, in the placebo group, but not in the propranolol group, memory vividness significantly decreased from pretest to posttest and follow-up after recall+EMs relative to the control conditions. CONCLUSIONS: Blocking NA abolished the effects of EMs on the vividness of emotional memories, indicating that NA is crucial for EMDR effectiveness and possibly strengthens the reconsolidation of the degraded memory.

Time matters: adenosine testing immediately after pulmonary vein isolation does not substitute a waiting period.

AIMS: Adenosine testing can reveal dormant pulmonary vein (PV) conduction after PV antrum isolation (PVAI). However, the optimal timing for adenosine administration is unknown. We hypothesized that adenosine testing immediately after PVAI reliably reveals PV reconnection and thereby eliminates the need for an observation period. METHODS AND RESULTS: Fifty patients underwent PVAI. Immediately after isolation of a PV pair, adenosine was administered. Both PV pairs were separately tested. If adenosine restored PV conduction, PVs were re-isolated. During a ≥30 min observation period after immediate adenosine-guided isolation, spontaneous reconnection was assessed and reconnected PVs were re-isolated. After the observation period, adenosine testing was repeated. Immediate adenosine testing revealed dormant conduction in 10.4% of the left PVs and 16.3% of the right PVs. All PVs were successfully re-isolated. During a mean observation period of 36 ± 10 min, spontaneous reconnection occurred in 8.2% of the left and 16.3% of the right PVs. None of these PVs had shown reconnection during immediate testing. Late adenosine testing revealed dormant conduction in 12.5% of the left and 16.3% of the right PVs. In patients without reconnection during immediate adenosine testing, 14.6% of the left PVs and 30.6% of the right PVs showed either spontaneous reconnection or restored PV conduction during late adenosine testing. CONCLUSION: Adenosine testing immediately after PVAI does not reliably exclude later spontaneous or adenosine-induced PV reconnection. Adenosine testing should be performed after an appropriate observation period to reduce risk of PV reconnection.
