Adult attachment, posttraumatic growth and negative emotions among former political prisoners
Although traumatic events are generally associated with negative psychosocial consequences, trauma survivors also report positive changes in themselves, human relationships and spirituality. Our aims are, first to study associations between exposure to torture and ill-treatment and posttraumatic growth and negative emotions, and second, to examine the role of adult attachment in moderating the association between exposure and positive growth. The participants were 275 Palestinian men imprisoned in a political context. They completed the Posttraumatic Growth Inventory (PTGI), adult attachment questionnaire (AAQ) and reported exposure to traumatic events. The results show that a high level of torture and ill-treatment was associated with a low level of posttraumatic growth and a high level of negative emotions. However, adult attachment style moderated that association, among men with secure attachment
Learning curve in robotic-assisted lobectomy for non-small cell lung cancer is not steep after experience in video-assisted lobectomy; single-surgeon experience using cumulative sum analysis
Publisher Copyright: © 2021Background: Robotic assistance in lung lobectomy has been suggested to enhance the adoption of minimally invasive techniques among surgeons. However, little is known of learning curves in different minimally invasive techniques. We studied learning curves in robotic-assisted versus video- assisted lobectomies for lung cancer. Methods: A single surgeon performed his first 75 video-assisted thoracic surgery (VATS) lobectomies from April 2007 to November 2012, and his 75 first robotic-assisted thoracic surgery (RATS) lobectomies between August 2011 and May 2018. A retrospective chart review was done. Cumulative sum (CUSUM) analysis was used to identify the learning curve. Results: No operative deaths occurred for VATS patients or RATS patients. Conversion-to-open rate was significantly lower in the RATS group (2.7% vs. 13.3%, p = 0.016). Meanwhile, 90-day mortality (1.3% vs. 5.3%, p = 0.172), postoperative complications (24% vs. 24%, p = 0.999), re- operation rates (4% vs. 5.3%, p = 0.688), operation time (170±56 min vs. 178±66 min, p = 0.663) and length of stay (8.9 ± 7.9 days vs. 8.2 ± 5.8 days, p = 0.844) were similar between the two groups. Based on CUSUM analysis, learning curves were similar for both procedures, although slightly shorter for RATS (proficiency obtained with 53 VATS cases vs. 45 RATS cases, p = 0.198). Conclusions: Robotic-assisted thoracoscopic lung lobectomy can be implemented safely and efficiently in an expert center with earlier experience in VATS lobectomies. However, there seems to be a learning curve of its own despite the surgeon's previous experience in conventional thoracoscopic surgery.Peer reviewe
Thoracotomy and VATS Surgery in Local Non-Small-Cell Lung Cancer : Differences in Long-Term Health-Related Quality Of Life
Very long-term health-related quality of life (HRQoL) is an important end point in operated early stage non-small-cell lung cancer with good prognosis. The results for very long-term HRQoL after minimally invasive video-assisted thoracoscopic surgery (VATS) has not been evaluated and compared to thoracotomy. Surprisingly, inferior overall HRQoL was evident for patients operated with VATS, independent of preoperative factors including age, comorbidities, and pulmonary function tests. Background: As a result of routine low-dose computed tomographic screening, lung cancer is more frequently diagnosed at earlier, operable stages of disease. In treating local non-small-cell lung cancer, video-assisted thoracoscopic surgery (VATS), a minimally invasive surgical approach, has replaced thoracotomy as the standard of care. While short-term quality-of-life outcomes favor the use of VATS, the impact of VATS on long-term health-related quality of life (HRQoL) is unknown. Patients and Methods: We studied patients who underwent lobectomy for the treatment of non-small-cell lung cancer from January 2006 to January 2013 at a single institution (n = 456). Patients who underwent segmentectomy (n = 27), who received neoadjuvant therapy (n = 13), or who were found to have clinical stage > T2 or > NO disease (n = 45) were excluded from analysis. At time of HRQoL assessment, 199 patients were eligible for study and were mailed the generic HRQoL instrument 15D. Results: A total of 180 patients (90.5%) replied; 92 respondents underwent VATS while 88 underwent open thoracotomy. The VATS group more often had adenocarcinoma (P = .006), and lymph node stations were sampled to a lesser extent (P = .004); additionally, hospital length of stay was shorter among patients undergoing VATS (P = .001). No other clinical or pathologic differences were observed between the 2 groups. Surprisingly, patients who underwent VATS scored significantly lower on HRQoL on the dimensions of breathing, speaking, usual activities, mental function, and vitality, and they reported a lower total 15D score, which reflects overall quality of life (P <.05). Conclusion: In contrast to earlier short-term reports, long-term quality-of-life measures are worse among patients who underwent VATS compared to thoracotomy. (C) 2019 Elsevier Inc.

Clinical Features in Patients With Malignant Pleural Mesothelioma With 5-Year Survival and Evaluation of Original Diagnoses
Within a larger national malignant pleural mesothelioma cohort, we identified 43 patients with unusually long survival times. This study aimed to evaluate the diagnostic accuracy in this subgroup, and the diagnosis was confirmed to be correct in most cases. In addition, we searched for clinical factors related to the prolonged survival time. Introduction: Malignant pleural mesothelioma (MPM) is a fatal malignancy strongly associated with previous asbestos exposure. Overall survival remains dismal, partly owing to poor response to available treatment. The aims of this study were to evaluate diagnostic accuracy in a group of patients with MPM with an unusually long survival time and to assess the factors related to this prolonged survival. Materials and Methods: Forty-three patients with overall survival exceeding 5 years were accepted to the long-term survivor (LTS) group, and these patients were compared with 84 patients with epithelial MPM. Data were collected from various national registries and electronic medical records. In addition, all available histopathologic diagnostic samples and computed tomography studies were re-evaluated by experienced specialists. Results: Our study showed a good diagnostic accuracy, with only 1 (0.5%) patient having an incorrect MPM diagnosis. Two (0.9%) localized malignant mesotheliomas and 2 (0.9%) well-differentiated papillary mesotheliomas were also found. LTS patients were younger, more frequently female, had a better performance status at time of diagnosis, and had less evidence of prior asbestos exposure. In multivariate analysis, we showed tumor size, Eastern Cooperative Oncology Group performance status, and first-line treatment (both surgery and chemotherapy) to be associated with survival time. Conclusion: We confirmed the diagnosis of MPM in an overwhelming majority of patients in the LTS group. An epithelial subtype of MPM behaving clinically more indolently seems to exist, but further tumor and genetic characterization is needed. The prolonged survival time is most likely explained by a combination of tumor-, patient-, and treatment-related factors. (C) 2020 Elsevier Inc. All rights reserved.Peer reviewe
A genome-wide approach accounting for body mass index identifies genetic variants influencing fasting glycemic traits and insulin resistance
Recent genome-wide association studies have described many loci implicated in type 2 diabetes (T2D) pathophysiology and beta-cell dysfunction, but contributed little to our understanding of the genetic basis of insulin resistance. We hypothesized that genes implicated in insulin resistance pathways may be uncovered by accounting for differences in body mass index (BMI) and potential interaction between BMI and genetic variants. We applied a novel joint meta-analytical approach to test associations with fasting insulin (FI) and glucose (FG) on a genome-wide scale. We present six previously unknown FI loci at P<5×10−8 in combined discovery and follow-up analyses of 52 studies comprising up to 96,496non-diabetic individuals. Risk variants were associated with higher triglyceride and lower HDL cholesterol levels, suggestive of a role for these FI loci in insulin resistance pathways. The localization of these additional loci will aid further characterization of the role of insulin resistance in T2D pathophysiology
New genetic loci link adipose and insulin biology to body fat distribution.
Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms
Genetic insights into resting heart rate and its role in cardiovascular disease
Resting heart rate is associated with cardiovascular diseases and mortality in observational and Mendelian randomization studies. The aims of this study are to extend the number of resting heart rate associated genetic variants and to obtain further insights in resting heart rate biology and its clinical consequences. A genome-wide meta-analysis of 100 studies in up to 835,465 individuals reveals 493 independent genetic variants in 352 loci, including 68 genetic variants outside previously identified resting heart rate associated loci. We prioritize 670 genes and in silico annotations point to their enrichment in cardiomyocytes and provide insights in their ECG signature. Two-sample Mendelian randomization analyses indicate that higher genetically predicted resting heart rate increases risk of dilated cardiomyopathy, but decreases risk of developing atrial fibrillation, ischemic stroke, and cardio-embolic stroke. We do not find evidence for a linear or non-linear genetic association between resting heart rate and all-cause mortality in contrast to our previous Mendelian randomization study. Systematic alteration of key differences between the current and previous Mendelian randomization study indicates that the most likely cause of the discrepancy between these studies arises from false positive findings in previous one-sample MR analyses caused by weak-instrument bias at lower P-value thresholds. The results extend our understanding of resting heart rate biology and give additional insights in its role in cardiovascular disease development
Associations between self and other representations and posttraumatic adjustment among political prisoners
The content and structure of self and other representations and their association with posttraumatic stress symptoms, somatic symptoms, and positive growth were studied among 117 Palestinian male political prisoners. Further, the associations between the representations and the severity of trauma and the post-detention conditions (such as education, place of residency and employment), and the role of representation patterns as a moderator between trauma exposure and symptoms was studied. Cluster analysis identified three representation patterns based on participants' descriptions of their spouse and themselves, and of childhood relationships with their mother and father. Representation patterns differed in negative vs. positive content and in the levels of differentiation and conceptual maturity: The Malevolent Others and Defeated Self representation pattern was characterized by very negative content, and
Conceptualizing Perceived Benefits and Investigating Its Role in Adoption of Tablet Computers among Newspaper Subscribers
Part 6: New Services Adoption and Ecological BehaviourInternational audienceThis paper conceptualizes perceived benefit as a combination of eco-consciousness, social prestige, and extra services and proposes a research model for user acceptance of tablet computers. The model was tested among newspaper subscribers (n = 904) in one of the Nordic countries using Structural Equation Modeling (SEM).The findings suggest that attitude toward tablet devices is predicted by eco-consciousness, ease of use, social prestige, and extra services. In turn, attitude along with intention to use predict intention to buy. Furthermore, ease of use was also found to predict extra services
