The Four Psychological Symptoms Which Can Make Myocardial Infarction Worse
A group of Dutch investigators has identified 4 psychological symptoms which can be associated with increased risk of depression after myocardial infarction, as reported in the November issue of Psychotherapy and Psychosomatics, where the Authors suggests that screening for depression in myocardial infarction (MI) patients must be improved: (1) depression often goes unrecognized and (2) anxiety has been largely overlooked as an essential feature of depression in these patients.
They therefore examined the co-occurrence of anxiety and depression after MI, and the validity of a brief mixed anxiety-depression index as a simple way to identify post-MI patients at increased risk of comorbid depression. One month after MI, 176 patients underwent a psychiatric interview and completed the Beck Depression Inventory (BDI) and the Symptoms of Anxiety-Depression index (SAD4) containing four symptoms of anxiety (tension, restlessness) and depression (feeling blue, hopelessness).
Thirty-one MI patients (18%) had comorbid depression and 37 (21%) depressive or anxiety disorder. High factor loadings and item-total correlations (SAD4, = 0.86) confirmed that symptoms of anxiety and depression co-occurred after MI.
Mixed anxiety-depression (SAD43) was present in 90% of depressed MI patients and in 100% of severely depressed patients. After adjustment for standard depression symptoms (BDI; OR = 4.4, 95% CI 1.6-12.1, p = 0.004), left ventricular ejection fraction, age and sex, mixed anxiety-depression symptomatology was associated with an increased risk of depressive comorbidity (OR = 11.2, 95% CI 3.0-42.5, p
Anxiety is underrecognized in post-MI patients; however, the present findings suggest that anxiety symptomatology should not be overlooked in these patients. Depressive comorbidity after MI is characterized by symptoms of mixed anxiety-depression, after controlling for standard depression symptoms. The SAD4 represents an easy way to recognize the increased risk of post-MI depression.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Mapping the interaction of a single atom with a single photon may inform design of quantum devices
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
