Clinical Factors Influencing Quality of Life in Anorexia Nervosa Patients

Anorexia Nervosa (AN) is a psychological and possibly life-threatening eating disorder defined by an extremely low body weight relative to stature, extreme and needless weight loss, illogical fear of weight gain, and distorted perception of self-image and body. Among eating disorders, anorexia nervosa has been proving a difficult condition, with many patients remaining ill for many years. The purpose of this study was to elucidate clinical factors influencing quality of life (QOL) in anorexia nervosa (AN) patients. 

Twenty female patients with AN (median age = 30.0 years old, quartile deviation = 6.8) and forty female healthy controls (HC) (median age = 30.0 years old, quartile deviation = 8.6) participated in the study. QOL was assessed with the 36-Item Short Form Health Survey (SF-36) and social support was evaluated using the Multidimensional Scale of Perceived Social Support (MSPSS). Clinical symptoms were evaluated with the Structured Interview Guide for the Hamilton Depression Rating Scale (SIGH-D) and the Eating Disorder Inventory-2 (EDI-2). 

Scores of the SF-36 Mental Component Summary (MCS) (U = 124.0, P < 0.0001) and Role/Social Component Summary (RCS) (U = 223.0, P = 0.006) and scores of total (U = 108.0, P < 0.0001) and subscales of the MSPSS were lower in AN group than HC group, and the SIGH-D score was higher (U = 46.0, P < 0.0001) in AN group than HC group. Scores of the SIGH-D (ρ = −0.565, P < 0.05) and subscales of the EDI-2 Interoceptive Confusion (ρ = −0.556, P < 0.05), Interpersonal Difficulty (ρ = −0.581, P < 0.05) and Negative Self-image (ρ = −0.617, P < 0.05) were negatively correlated to MCS, and score of Interoceptive Confusion subscale showed a negative correlation to RCS (ρ = −0.672, P < 0.05). Moreover, stepwise regression analysis showed that the SIGH-D score was an independent predictor of MCS and Interoceptive Confusion score predicted RCS. 

In conclusion, the results suggest that not only depressive symptoms but also poor emotional awareness and impaired sense of control are much more important as influencing factors on AN patients’ QOL than other clinical factors.

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...

Remarks on the Complexity of Signed k-Domination on Graphs

ABSTRACT This paper is motivated by the concept of the signed k-domination problem and dedicated to the complexity of the problem on graphs. For any fixed nonnegative integer k, we show that the signed k-domination problem is NP-complete for doubly chordal graphs. For strongly chordal graphs and distance-hereditary graphs, we show that the signed k-domination problem can be solved in polynomial time. We also show that the problem is linear-time solvable for trees, interval graphs, and chord...
