BACKGROUND: Although obesity is an established risk factor for developing colon cancer, its prognostic impact and relation to patient sex in colon cancer survivors remains unclear. METHODS: The authors examined the prognostic and predictive impact of the body mass index (BMI) in patients with stage II and III colon carcinoma (N = 25,291) within the Adjuvant Colon Cancer Endpoints (ACCENT) database. BMI was measured at enrollment in randomized trials of 5-fluorouracil-based adjuvant chemotherapy. Association of BMI with the time to recurrence (TTR), disease-free survival (DFS), and overall survival (OS) were determined using Cox regression models. Statistical tests were 2-sided. RESULTS: During a median follow-up of 7.8 years, obese and underweight patients had significantly poorer survival compared with overweight and normal-weight patients. In a multivariable analysis, the adverse prognostic impact of BMI was observed among men but not among women (Pinteraction =.0129). Men with class 2 and 3 obesity (BMI ≥35.0 kg/m2) had a statistically significant reduction in DFS (hazard ratio [HR], 1.16; 95% confidence interval [CI], 1.01-1.33; P =.0297) compared with normal-weight patients. Underweight patients had a significantly shorter TTR and reduced DFS (HR, 1.18; 95% CI, 1.09-1.28; P <.0001) that was more significant among men (HR, 1.31; 95% CI, 1.15-1.50; P <.0001) than among women (HR, 1.11; 95% CI, 1.01-1.23; P =.0362; Pinteraction =.0340). BMI was not predictive of a benefit from adjuvant treatment. CONCLUSIONS: Obesity and underweight status were associated independently with inferior outcomes in patients with colon cancer who received treatment in adjuvant chemotherapy trials. © 2013 American Cancer Society.

This study assessed the safety and tolerability of sertindole in the long-term treatment of schizophrenia. An open-label, noncomparative, flexible-dose study was carried out in 11 European countries. Upon completion of an 8-week, haloperidol-referenced randomized clinical trial with sertindole, patients were offered sertindole maintenance treatment up to 18 months. In total, 294 patients were enrolled, of whom 237 (81%) had received sertindole and 57 (19%) had received haloperidol in the lead-in trial. The modal dose during the maintenance period was 16 mg/day. Patients showed therapeutic improvement indicated by significant decreases in the Positive And Negative Syndrome Scale and Clinical Global Impression 'severity-of-illness' scores. An adverse event was the primary reason for withdrawal in 13% of patients. The most common adverse events were fatigue and weight gain, both with incidences of 14%. The incidence of extrapyramidal symptoms was 18%, and 11% of the patients required anticholinergic medication. No statistically significant changes were observed in laboratory values or vital signs, but the mean serum prolactin levels decreased. The mean change in weight from baseline to the last assessment was 2.7 kg. The largest weight increase was observed in patients who were underweight at baseline. Long-term treatment with sertindole was safe and well tolerated, and patients showed clinical improvement beyond acute treatment. © 2012 Wolters Kluwer Health.

Chest wall reconstructions can be complex and challenging procedures, especially when huge thoracic defects have been generated by radical excisions. Nonrigid reconstructions with meshes or patches have the goal of avoiding a lung hernia caused by the chest wall defect, or preventing the impaction of the scapula in case of posterior chest wall resections, especially when the resection is extended down to the 5th and 6th ribs. Large anterior and lateral resections result in thoracic instability and alteration of pulmonary physiology, and render intrathoracic structures vulnerable to external impact. They necessitate rigid reconstructions according to several techniques using alloplastic materials (eg, methyl methacrylate-based customized plates or neo-ribs, osteosynthesis systems, or dedicated prosthesis). Nowadays, the availability of these multiple, possibly combined, more adapted, and better tolerated materials have pushed past the limits of resection to those involving soft tissue coverage. © 2010 Elsevier Inc.

Thymic epithelial tumors (TETs) are rare thoracic malignancies, with an overall incidence of 1.5 per million people. The TET Registry Project aims at federating an international network to provide a resource to support studies on the epidemiology and clinical management and monitoring some standards of clinical care of these tumors. Recorded data span all the specifications of the management of TET: paraneoplastic syndromes, histologic subtypes, diagnostic and staging issues, multimodal treatment strategies, and exceptional surgeries and therapies. Data collection for the registry is done both prospectively and retrospectively through different paths to allow the involvement of as many centers as possible, including data-sharing arrangements with some already established databases. This ambitious project implies the early setting of strong quality assurance measures looking at completeness, consistency, and accuracy of the data. These measures require a significant and long-term financial support that will also be free of possible sources of conflicts of interests. © 2011 Elsevier Inc.

The aim of this study was to evaluate the psychometric properties of the Problematic Mobile Phone Use Scale (PMPUS) for Turkish Adolescents. The psychometric properties of PMPUS were tested in two separate sample groups that consisted of 950 Turkish high school students. The first sample group (n=309) was used to determine the factor structure of the scale. The second sample group (n=461) was used to test data conformity with the identified structure, discriminant validity and concurrent scale validity, internal consistency reliability calculations, and item statistics calculations. The results of exploratory factor analyses indicated that the scale had three factors: interference with negative effect, compulsion/persistence, and withdrawal/tolerance. The results showed that item and construct reliability values yielded satisfactory rates in general for the three-factor construct. On the other hand, the average variance extracted value remained below the scale value for three subscales. The scores for the scale significantly correlated with depression and loneliness. In addition, the discriminant validity value was above the scale in all sub-dimensions except one. Based on these data, the reliability of the PMPUS scale appears to be satisfactory and provides good internal consistency. Therefore, with limited exception, the PMPUS was found to be reliable and valid in the context of Turkish adolescents. © Copyright 2012, Mary Ann Liebert, Inc.
