Peripheral VA-ECMO with direct biventricular decompression for refractory cardiogenic shock.

Cardiogenic shock and cardiac arrest are life-threatening emergencies that result in high mortality rates. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) via peripheral cannulation is an option for patients who do not respond to conventional therapies. Left ventricular (LV) distention is a major limitation with peripheral VA-ECMO and is thought to contribute to poor recovery and the inability to wean off VA-ECMO. We report on a novel technique that combines peripheral VA-ECMO with off-pump insertion of a trans-apical LV venting cannula and a right ventricular decompression cannula.

The cognitive-behavioural model of hoarding disorder: Evidence from clinical and non-clinical cohorts.

The cognitive-behavioural model of hoarding disorder incorporates information processing difficulties, maladaptive attachment to possessions, erroneous beliefs about the nature of possessions, and mood problems as etiologically significant factors, although developmental experiences such as a compromised early family environment have also been proposed in an augmented model. This study examined the specificity and relevance of variables highlighted in the augmented cognitive-behavioural model. Various clinical participants (n = 89) and community controls (n = 20) were assessed with structured clinical interviews to verify diagnosis. Participants completed self-report measures of hoarding severity, cognitions, meta-memory, and early developmental experiences (e.g., memories of warmth and security in one's family). Hoarding cohorts (with and without obsessive-compulsive disorder) reported poor confidence in memory, but relative to other groups (obsessive-compulsive disorder without hoarding disorder, anxiety disorders, and healthy controls), hoarding-relevant cognitions, need to keep possessions in view, and concerns about the consequences of forgetting were significantly higher. Hoarding groups reported the lowest recollections of warmth in their family, although no differences were found between hoarding and non hoarding clinical cohorts for uncertainty about self and others. Nonetheless, clinical cohorts reported generally higher scores of uncertainty than healthy controls. When predicting hoarding severity, after controlling for age and mood, recollections of lack of warmth in one's family was a significant predictor of hoarding severity, with hoarding-related cognitions and fears about decision-making being additional unique predictors. The study supports the augmented cognitive-behavioural model of hoarding, inclusive of the importance of early developmental influences in hoarding.

Emotion regulation difficulties in obsessive-compulsive disorder.

OBJECTIVE: Emotion regulation difficulties are implicated in psychological disorders but their role in obsessive-compulsive disorder (OCD) is unclear. Two studies examining these difficulties in OCD are presented. METHOD: A community sample (Study 1; n = 306) and a clinical OCD sample (Study 2; n = 59) completed the Difficulties in Emotion Regulation Scale (DERS) and measures of depression, anxiety, and OCD. In Study 2, the OCD sample was compared to a matched control group (n = 59, selected from Study 1). RESULTS: In Study 1, OCD was positively correlated with DERS total and subscale scores, and the DERS significantly predicted OCD severity even after accounting for age, gender, depression, and anxiety. In Study 2, emotion regulation difficulties were significantly higher in the clinical sample compared to the matched control group, even after accounting for depression and anxiety. CONCLUSION: Results showed that emotion regulation difficulties in OCD cannot simply be attributed to mood difficulties. Theoretical and treatment implications are discussed.

Short-Term Cognitive-Behavioural Group Treatment for Hoarding Disorder: A Naturalistic Treatment Outcome Study.

The study aim was to test whether a 12-week publically rebated group programme, based upon Steketee and Frost's Cognitive Behavioural Therapy-based hoarding treatment, would be efficacious in a community-based setting. Over a 3-year period, 77 participants with clinically significant hoarding were recruited into 12 group programmes. All completed treatment; however, as this was a community-based naturalistic study, only 41 completed the post-treatment assessment. Treatment included psychoeducation about hoarding, skills training for organization and decision making, direct in-session exposure to sorting and discarding, and cognitive and behavioural techniques to support out-of-session sorting and discarding, and nonacquiring. Self-report measures used to assess treatment effect were the Savings Inventory-Revised (SI-R), Savings Cognition Inventory, and the Depression, Anxiety and Stress Scales. Pre-post analyses indicated that after 12 weeks of treatment, hoarding symptoms as measured on the SI-R had reduced significantly, with large effect sizes reported in total and across all subscales. Moderate effect sizes were also reported for hoarding-related beliefs (emotional attachment and responsibility) and depressive symptoms. Of the 41 participants who completed post-treatment questionnaires, 14 (34%) were conservatively calculated to have clinically significant change, which is considerable given the brevity of the programme judged against the typical length of the disorder. The main limitation of the study was the moderate assessment completion rate, given its naturalistic setting. This study demonstrated that a 12-week group treatment for hoarding disorders was effective in reducing hoarding and depressive symptoms in an Australian clinical cohort and provides evidence for use of this treatment approach in a community setting.

KEY PRACTITIONER MESSAGE: A 12-week group programme delivered in a community setting was effective for helping with hoarding symptoms with a large effect size. Hoarding beliefs (emotional attachment and responsibility) and depression were reduced, with moderate effect sizes. A third of all participants who completed post-treatment questionnaires experienced clinically significant change. Suggests that hoarding CBT treatment can be effectively translated into real-world settings and into a brief 12-session format, albeit the study had a moderate assessment completion rate.

Obsessive-compulsive disorder and comorbid depression: the role of OCD-related and non-specific factors.

Although comorbid depression is a predictor of poor treatment response in obsessive-compulsive disorder (OCD), there is limited understanding of factors that contribute to depression severity in OCD. The current study examines the influence of OCD-related factors (autogenous obsessions and obsessional beliefs) and non-specific factors (avoidance and anxiety) on depression severity in a sample of OCD patients. There were 56 participants with only OCD and 46 with OCD and comorbid depression. Self-report questionnaires measuring depression, OCD-related factors, and non-specific factors were completed. Although there were no significant differences between the two groups on these variables, depression severity was positively correlated with anxiety, avoidance, obsessional beliefs, and autogenous obsessions in the whole sample. When entered into a multiple regression model to predict depression severity, these factors accounted for 51% of the variance. While OCD-related factors remained significant predictors after controlling for non-specific factors, the non-specific factors made the most significant contributions to the model. Our findings suggest that in addition to dealing with autogenous obsessions, addressing anxiety and avoidance might lead to improvements in the treatment of OCD with comorbid depression.

Rationale of platelet gel to augment adaptive remodeling of the injured heart.

Cardiac pathologic events including; myocardial infarction, viral infection and hypertrophy, and aging, may trigger maladaptive remodeling of the myocardium. Maladaptive remodeling results in diastolic and systolic dysfunction, myocyte loss, and malformation of the extracellular matrix. It is proposed that platelet gel applied to the site of myocardial injury may provide the proper cytokines, growth factors, and chemokines to promote adaptive remodeling. The hypothesis is that platelet gel concentrates may provide a temporary and local hyperphysiologic concentration of platelet secretory factors that may initiate adaptive myocardial healing. Autologous platelet gel can be derived from concentrated platelets activated and induced to secrete cytokines, growth factors, and chemokines with an array of stimulating agents. This report discusses selected platelet secretory factors, including; IL-1beta, TGF-beta, TGF-alpha, FGF, EGF, PDGF, and IGF, which support the concept that platelet concentrates can mediate cardiac wound healing. In conclusion, application of platelet gel to areas of cardiac injury may offer a therapeutic means to stimulate myocyte regeneration, angiogenesis, and restoration of a normal extracellular matrix composition.
