Given the long-term functional and survival advantage, we have been consciously exploring
the feasibility of a biventricular repair in these patients when they present later for Fontan completion.
Since June 2009, 71 patients were referred for staged completion of the Fontan procedure. Following detailed evaluation that included three-dimensional echocardiography and magnetic resonance imaging, 10 patients (Group 1-median age 6 years) were identified and later underwent complex biventricular repair with takedown of Glenn shunt, while completion MLN2238 of extracardiac Fontan repair was done in 61 patients (Group 2-median age 7 years).
Two-ventricle repair was accomplished in all the 10 Group 1 patients. One patient developed complete heart block requiring permanent pacemaker insertion. Late patch dehiscence occurred in another (awaiting repair). At a median follow-up of 15 months, there was no mortality among the Group 1 patients and all except for 1 patient were symptom free. There were 2 early deaths (3.3%) in the Group 2 patients.
Two-ventricular repair, although surgically challenging, should be considered in all patients with two functional ventricles who come for Fontan completion. Comprehensive preoperative imaging and meticulous planning helps
in identifying suitable candidates.”
“Background: This study investigates whether an analysis, based on Item Response Theory (IRT), can be used for initial evaluations of depression
assessment instruments in a limited patient learn more sample from an affective disorder outpatient clinic, with the aim to finding major advantages and deficiencies of the instruments.
Methods: Three depression assessment instruments, the depression module from the Patient Health Questionnaire (PHQ9), the depression subscale of Affective Self Rating Scale (AS-18-D) and the Montgomery-angstrom sberg Depression Rating Scale (MADRS) were evaluated in a sample of 61 patients with affective disorder diagnoses, mainly bipolar disorder. A ’3- step IRT strategy’ was used.
Results: In a first step, the Mokken non-parametric analysis showed that PHQ9 and AS-18-D had strong overall scalabilities of 0.510 [C.I. 0.42, 0.61] and 0,513 [C.I. 0.41, 0.63] respectively, while MADRS had a weak scalability of SRT2104 in vitro 0.339 [C.I. 0.25, 0.43]. In a second step, a Rasch model analysis indicated large differences concerning the item discriminating capacity and was therefore considered not suitable for the data. In third step, applying a more flexible two parameter model, all three instruments showed large differences in item information and items had a low capacity to reliably measure respondents at low levels of depression severity.
Conclusions: We conclude that a stepwise IRT-approach, as performed in this study, is a suitable tool for studying assessment instruments at early stages of development.
