Infarction of the septomarginal band and tricuspid papillary muscle rupture related to alcohol septal ablation for hypertrophic cardiomyopathy

We presented a 77‐year‐old man with hypertrophic obstructive cardiomyopathy applied with flail tricuspid leaflet and severe tricuspid regurgitation leading to right heart failure 2 months after the failed septal ablation. The ruptured anterior tricuspid papillary muscle resulted from infarction of the base of anterior papillary muscle of the right ventricle (RV) confirmed by magnetic resonance imaging. As the septomarginal band is frequently lit up by intracoronary contrast that particular attention should be paid to the RV papillary muscles. And, if the papillary muscles or the RV free wall is brightened, then the use of that septal artery should be avoided.     

Predictors of quality of life and functional impairment in Obsessive–Compulsive Disorder

Obsessive–compulsive disorder (OCD) is the 10th leading cause of disability among health conditions; yet, relatively little research has focused on quality of life (QOL) and functional impairment in OCD. The present study extended existing work by examining correlates and predictors of QOL and functional impairment in 96 treatment-seeking OCD patients (in intensive outpatient and residential settings). In a model including OCD symptoms and related phenomena, and symptoms of depression and anxiety, two main findings emerged: (a) depressive symptoms predicted both QOL and functional impairment, and (b) contamination symptoms predicted functional impairment. These findings are discussed in terms of the implications for studying QOL and functional impairment in OCD. Future research should investigate the factors that predict changes in QOL and functional impairment following treatment.     

Inequality in oral health‐related quality of life before and after a major subsidization reform

In Finland, a dental subsidization reform, implemented in 2001–2002, abolished age restrictions on subsidized dental care. We investigated income‐related inequality in oral health‐related quality of life (OHRQoL) and its determinants among adult Finns before and after the reform. Three cross‐sectional postal surveys, focusing on perceived oral health and the use of dental services among people born before 1971, were conducted in 2001 (n = 2,046), 2004 (n = 1,728), and 2007 (n = 1,560). Five measures, based on the Oral Health Impact Profile‐14, were used as indicators of OHRQoL. Income‐related inequality and associated factors were analysed using the concentration index and its decomposition. Prevalence, extent, and severity of oral health impacts were slightly lower in 2007 than in 2001. The oral health impacts were concentrated, at all study time points, among individuals with lower income. Most of the inequality was related to self‐perceived general health, tooth loss, and income. Contributions of time since the last dental visit and satisfaction with the last treatment period to the inequality decreased from 2001 to 2007. However, the contributions of these factors were already small (10–20%) in 2001. In general, OHRQoL improved slightly; however, no clear or dramatic change in inequality in OHRQoL was seen after the reform.     

Randomized,double-blind,placebo-controlled,safety and immunogenicity study of 4 formulations of Anthrax Vaccine Adsorbed plus CPG 7909 (AV7909) in healthy adult volunteers

A new anthrax vaccine that could accelerate the immune response and possibly reduce the number of injections needed for protection would be desirable in a post-exposure setting.     

Mutational Analysis of Quinolone Resistance Protein QnrB1

Alanine substitutions and selected deletions have been used to localize amino acids in QnrB essential for its protective activity. Essential amino acids are found at positions i and i⁻² in the pentapeptide repeat module and in the larger of two loops, where deletion of only a single amino acid compromises activity. Deletion of 10 amino acids at the N terminus is tolerated, but removal of 3 amino acids in the C-terminal dimerization unit destroys activity.     

Self-Punishment as a Maladaptive Thought Control Strategy Mediates the Relationship Between Beliefs About Thoughts and Repugnant Obsessions

Cognitive-behavioral models of obsessive–compulsive disorder (OCD) propose that erroneous beliefs about the importance and need to control thoughts lead individuals with OCD to overuse maladaptive thought control strategies such as worry and self-punishment. These strategies are thought to backfire, leading to obsessional symptoms. Whereas previous studies have examined predictors of the use of thought control strategies, none have investigated these strategies as mediators in the prediction of OCD symptom severity. An additional gap in the literature is the lack of attention to OCD symptom dimensions. The present study, therefore, extended existing work by examining thought control strategies as mediators of the relationship between obsessive beliefs and OCD symptom dimensions in a treatment-seeking sample of 102 adults with OCD. In line with our hypotheses, the use of punishment (but not worry) as a thought control tactic mediated the relationship between dysfunctional beliefs about the importance/control of thoughts and unacceptable obsessions. These findings are discussed in terms of the conceptualization and treatment of OCD. Future research should investigate the extent to which these various thought control strategies may be helpful versus harmful using idiographic measures of thought control and employing experimental designs.
