RESUMO

BACKGROUND: Neurocognitive impairment is a core feature of schizophrenia spectrum disorders (SSDs), and the relationship between cognition and symptoms in SSDs has been widely researched. Negative symptoms are related to a wide range of cognitive impairments; however, the aspects of negative symptoms that underpin this relationship have yet to be specified. STUDY DESIGN: We used iterative Constrained Principal Component Analysis (iCPCA) to explore the relationship between 18 cognitive measures (including processing speed, attention, working, spatial and verbal memory and executive functions) and 46 symptoms in schizophrenia at the individual item level while minimizing the risk of Type I errors. ICPCA was conducted on a sample of SSD patients in the early stages of psychiatric treatment (n = 121) to determine the components of cognition overlapping with symptoms measured by the Scale for the Assessment of Negative Symptoms (SANS) and the Scale for the Assessment of Positive Symptoms (SAPS). RESULTS: We found that a verbal memory component was associated with items from SANS and SAPS related to impoverished and disorganized emotional communication, language, and thought. In contrast, a working memory component was associated with SANS items related to motor system impoverishment. CONCLUSIONS: The iCPCA allowed us to explore the associations between individual items, optimized to understand the overlap between symptoms and cognition. The specific symptoms linked to verbal and working memory impairments imply distinct brain networks, which further investigation may lead to our deeper understanding of the illness and the development of treatment methods.

RESUMO

Introduction: The current article introduces the Loneliness Automatic Thoughts Questionnaire (LATQ) and describes research evaluating its psychometric properties and correlates. Methods: Two separate samples of university student participants (Study 1; N = 282, Study 2; N = 289) were administered the LATQ along with a battery of other measures. Whereas Study 1 involved a preliminary investigation of the psychometric properties of the LATQ, Study 2 provided an opportunity to further expand on this aim by assessing the concurrent validity of the measure across studies. Results: Overall, psychometric analyses confirmed that the LATQ items are measured with an adequate degree of internal consistency and confirmatory factor analyses established that the nine items loaded significantly on one replicable factor. Concurrent validity was established in terms of links with other loneliness measures and a measure of persistent and intrusive negative thoughts. Furthermore, LATQ scores were associated with anti-mattering, social hopelessness, anxiety, depression, and unbearable psychache. Moreover, regression analyses established that the LATQ predicted significant unique variance in depression and psychache beyond the variance attributable to measures of loneliness and adaptability to loneliness. Discussion: Collectively, results indicate that loneliness-related automatic thoughts represent a unique and important element of the loneliness construct. Future research applications and additional psychometric issues to address in future research are discussed and a need for a greater focus on the cognitive aspects of loneliness is explored.

RESUMO

BACKGROUND: High-risk patients undergoing abdominoperineal resection and pelvic exenteration may benefit from immediate flap reconstruction. However, there is currently no consensus on the ideal flap choice or patient for whom this is necessary. This study aimed to evaluate the long-term outcomes of using pedicled gracilis flaps for pelvic reconstruction and to analyze predictors of postoperative complications. METHODS: This was a retrospective review of a single reconstructive surgeon's cases between January 2012 and June 2021 identifying patients who underwent perineal reconstruction secondary to oncologic resection. Preoperative and outcome variables were collected and analyzed to determine the risk of developing minor and major wound complications. RESULTS: A total of 101 patients were included in the study with most patients (n = 88) undergoing unilateral gracilis flap reconstruction after oncologic resection. The mean follow-up period was 75 months. Of 101 patients, 8 (7.9%) developed early major complications, and an additional 13 (12.9%) developed late major complications. Minor complications developed in 33 patients (32.7%) with most cases being minor wound breakdown requiring local wound care. Most patients (n = 92, 91.1%) did not develop donor site complications. Anal cancer was significantly associated with early major complications, whereas younger age and elevated body mass index were significant predictors of developing minor wound complications. CONCLUSIONS: This study builds on our previous work that demonstrated the long-term success rate of gracilis flap reconstruction after large pelvic oncologic resections. A few patients developed donor site complications, and perineal complications were usually easily managed with local wound care, thus making the gracilis flap an attractive alternative to abdominal-based flaps.

RESUMO

INTRODUCTION: Video-based surgical coaching is gaining traction within the surgical community. It has an increasing adoption rate and growing recognition of its utility, especially an advanced continuous professional growth tool, for continued educational purposes. This method offers instructional flexibility in real-time remote settings and asynchronous feedback scenarios. In our first paper, we delineated fundamental principles for video-based coaching, emphasizing the customization of feedback to suit individual surgeon's needs. METHOD: In this second part of the series, we review into practical applications of video-based coaching, focusing on quality improvements in a team-based setting, such as the trauma bay. Additionally, we address the potential risks associated with surgical video recording, storage, and distribution, particularly regarding medicolegal aspects. We propose a comprehensive framework to facilitate the implementation of video coaching within individual healthcare institutions. RESULTS: Our paper examines the legal and ethical framework and explores the potential benefits and challenges, offering insights into the real-world implications of this educational approach. CONCLUSION: This paper contributes to the discourse on integrating video-based coaching into continuous professional development. It aims to facilitate informed decision-making in healthcare institutions, considering the adoption of this innovative educational quality tool.

RESUMO

BACKGROUND: Pelvic radiation plus sensitizing chemotherapy with a fluoropyrimidine (chemoradiotherapy) before surgery is standard care for locally advanced rectal cancer in North America. Whether neoadjuvant chemotherapy with fluorouracil, leucovorin, and oxaliplatin (FOLFOX) can be used in lieu of chemoradiotherapy is uncertain. METHODS: We conducted a multicenter, unblinded, noninferiority, randomized trial of neoadjuvant FOLFOX (with chemoradiotherapy given only if the primary tumor decreased in size by <20% or if FOLFOX was discontinued because of side effects) as compared with chemoradiotherapy. Adults with rectal cancer that had been clinically staged as T2 node-positive, T3 node-negative, or T3 node-positive who were candidates for sphincter-sparing surgery were eligible to participate. The primary end point was disease-free survival. Noninferiority would be claimed if the upper limit of the two-sided 90.2% confidence interval of the hazard ratio for disease recurrence or death did not exceed 1.29. Secondary end points included overall survival, local recurrence (in a time-to-event analysis), complete pathological resection, complete response, and toxic effects. RESULTS: From June 2012 through December 2018, a total of 1194 patients underwent randomization and 1128 started treatment; among those who started treatment, 585 were in the FOLFOX group and 543 in the chemoradiotherapy group. At a median follow-up of 58 months, FOLFOX was noninferior to chemoradiotherapy for disease-free survival (hazard ratio for disease recurrence or death, 0.92; 90.2% confidence interval [CI], 0.74 to 1.14; P = 0.005 for noninferiority). Five-year disease-free survival was 80.8% (95% CI, 77.9 to 83.7) in the FOLFOX group and 78.6% (95% CI, 75.4 to 81.8) in the chemoradiotherapy group. The groups were similar with respect to overall survival (hazard ratio for death, 1.04; 95% CI, 0.74 to 1.44) and local recurrence (hazard ratio, 1.18; 95% CI, 0.44 to 3.16). In the FOLFOX group, 53 patients (9.1%) received preoperative chemoradiotherapy and 8 (1.4%) received postoperative chemoradiotherapy. CONCLUSIONS: In patients with locally advanced rectal cancer who were eligible for sphincter-sparing surgery, preoperative FOLFOX was noninferior to preoperative chemoradiotherapy with respect to disease-free survival.

RESUMO

Stigma by association is described in qualitative research of family members who have relatives diagnosed with mental illness, depicting their sense of public shame for having these relationship ties. However, there have been relatively few empirical studies thus far, in part due to the isolation of family members affecting research recruitment. In order to address this gap, an online survey was administered to 124 family members, comparing those who live in the same home with their ill relative (n = 81) and those who do not (n = 43). A remarkable incidence of one in three family members reported experiencing stigma by association. Those living with an ill relative reported comparatively higher levels of stigma by association using an adapted questionnaire measure. Both groups experienced loneliness (moderate levels), but importantly, the cohabiting relatives perceived themselves as lacking support from friends and other family members. Correlational analyses revealed that those with heightened stigma by association reported heightened anti-mattering: that is, feeling that other people treat them as if they are insignificant and invisible. Anti-mattering was also associated with more loneliness and reduced social support. Our discussion focuses on the theme that family members who actually live with mentally ill relatives experience heightened social isolation that is under-recognized due to public stigma concerns, compounded by feeling their own lives do not matter to others. Public health implications are considered for the stigmatized family members who appear to be particularly marginalized.

RESUMO

The American Society of Colon and Rectal Surgeons (ASCRS) and the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) are dedicated to ensuring high-quality innovative patient care for surgical patients by advancing the science, prevention, and management of disorders and diseases of the colon, rectum, and anus as well as minimally invasive surgery. The ASCRS and SAGES society members involved in the creation of these guidelines were chosen because they have demonstrated expertise in the specialty of colon and rectal surgery and enhanced recovery. This consensus document was created to lead international efforts in defining quality care for conditions related to the colon, rectum, and anus and develop clinical practice guidelines based on the best available evidence. While not proscriptive, these guidelines provide information on which decisions can be made and do not dictate a specific form of treatment. These guidelines are intended for the use of all practitioners, healthcare workers, and patients who desire information about the management of the conditions addressed by the topics covered in these guidelines. These guidelines should not be deemed inclusive of all proper methods of care nor exclusive of methods of care reasonably directed toward obtaining the same results. The ultimate judgment regarding the propriety of any specific procedure must be made by the physician in light of all the circumstances presented by the individual patient. This clinical practice guideline represents a collaborative effort between the American Society of Colon and Rectal Surgeons (ASCRS) and the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) and was approved by both societies.

RESUMO

Purpose: Although individual differences in temperament have been shown to influence Quality of Life (QoL) among individuals with schizophrenia, there exists considerable heterogeneity in such outcomes suggesting moderating factors. Here we used event-related potential (ERP) methodology to examine whether the processing of facial emotions moderated the association between shyness and objective QoL among adults with schizophrenia.Methods: Forty stable outpatients with schizophrenia completed measures of shyness and QoL. Early visual ERP components (P100, N170) were recorded while participants viewed emotional faces.Results: We observed a significant interaction between shyness and P100 and N170 amplitudes in response to fearful faces in predicting Intrapsychic Foundations QoL. Patients with reduced P100 and N170 amplitudes to fearful compared to neutral faces displayed the lowest QoL, but only if they were also high in shyness. We also found a significant interaction between shyness and ERP latency at the P100 and N170 in response to happy faces. Patients who displayed longer P100 and N170 latencies to happy faces compared to neutral faces and with higher shyness levels scored lower on Intrapsychic Foundations and Interpersonal Relations QoL, respectively.Conclusion: These findings suggest that the neural processing of emotional faces and shyness interact to predict aspects of QoL among outpatients with schizophrenia.

RESUMO

BACKGROUND: While there is an established link between untreated psychosis and aggression, an enhanced understanding of the role of social cognition is still needed. AIMS: To examine social cognitive functioning among patients in a specialist forensic mental health service who had been deemed not criminally responsible for acts of violence due to a psychotic disorder. It was hypothesised, first, that such patients would show reduced social cognitive functioning compared with healthy, nonviolent comparison participants and, second, that those who continued to be aggressive while inpatients would demonstrate significant reductions compared to the now nonaggressive group. METHODS: The study samples were of 10 recently aggressive and 15 not-recently aggressive patients and 20 healthy, nonviolent comparison participants. Each completed the Toronto Empathy Questionnaire (TEQ), the Reading the Mind in the Eyes Test-Revised (RMET) and the Interpersonal Perception Task-15 (IPT-15). RESULTS: There was no significance between group differences on the RMET and TEQ. The patient group as a whole, however, showed significant interpersonal misperceptions, with specific misperceptions on IPT-15 deception and kinship subscales, while at the same time lacking self-awareness of their errors. Misperceptions on the IPT-15 competition subscale were unique to recently aggressive patients. CONCLUSIONS: Select aspects of reduced social cognitive functioning were found among not criminally responsible patients with psychosis who had committed violent acts and who continued to act aggressively while forensic inpatients. These findings enhance our understanding of the role of social cognition in predisposing toward violence and the potential importance of incorporating interventions which improve social cognition directly. We suggest also the potential for future research using virtual reality technologies in treatment.

RESUMO

OBJECTIVES: Several components are known to underlie goal-directed pursuit, including executive, motivational and volitional functions. These were explored in schizophrenia spectrum disorders in order to identify subgroups with distinct profiles. METHODS: Multiple executive, motivational and volitional tests were administered to a sample of outpatients with schizophrenia spectrum diagnoses (n = 59) and controls (n = 63). Research questions included whether distinct profiles exist and whether some functions are impacted disproportionately. These questions were addressed via cluster analysis and profile analysis, respectively. RESULTS: Some such functions were significantly altered in schizophrenia while others were unaffected. Two distinct profiles emerged, one characterized by energizing deficits, reduced reward sensitivity and few subjective complaints; while another was characterized by markedly increased punishment sensitivity, intact reward sensitivity and substantial subjective reporting of avolitional symptoms and boredom susceptibility. CONCLUSION: These findings highlight the importance of considering distinct patterns of strengths and deficits in functions governing goal-directed pursuit in schizophrenia that demarcate identifiable subtypes. These distinctions have implications for treatment, assessment and research.

RESUMO

The aim of this study is to better understand stigma towards individuals with mental illness who commit violent offences, and examine ways to mitigate the negative impact of social media news stories of schizophrenia and violent offending. Psychology undergraduate students (N = 255) were exposed to Instagram images and captions of recent real news stories of violent offending by individuals with schizophrenia. In the experimental condition, contextual clinical explanatory information was integrated. Pre- and post-measures of stigma were completed. There was a significant increase in negative attitudes towards individuals with mental illness who committed violent offences following the no-context condition, which was clearly mitigated in the experimental condition where context was provided. In both conditions, there were significant increases in intended social-distancing behaviours towards and perceptions of dangerousness of individuals with schizophrenia, and negative beliefs about mental illness more generally. There appears to be utility in incorporating knowledge-based clinical information to mitigate some facets of stigma.

RESUMO

BACKGROUND: Malignant peritoneal mesothelioma is a rare disease with poor outcomes. Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is the cornerstone of therapy. We aim to compare outcomes of malignant peritoneal mesothelioma treated at academic versus community hospitals. METHODS: This was a retrospective cohort study using the National Cancer Database to identify patients with malignant peritoneal mesothelioma from 2004 to 2016. Patients were divided according to treating facility type: academic or community. Outcomes were assessed using log-rank tests, Cox proportional-hazard modeling, and Kaplan-Meier survival statistics. RESULTS: In total, 2682 patients with malignant peritoneal mesothelioma were identified. A total of 1272 (47.4%) were treated at an academic facility and 1410 (52.6%) were treated at a community facility. Five hundred forty-six (42.9%) of patients at academic facilities underwent debulking or radical surgery compared to 286 (20.2%) at community facilities. Three hundred sixty-six (28.8%) of patients at academic facilities received chemotherapy on the same day as surgery compared to 147 (10.4%) of patients at community facilities. Unadjusted 5-year survival was 29.7% (95% CI 26.7-32.7) for academic centers compared to 18.3% (95% CI 16.0-20.7) for community centers. In multivariable analysis, community facility was an independent predictor of increased risk of death (HR: 1.19, 95% CI 1.08-1.32, p = 0.001). CONCLUSIONS: We demonstrate better survival outcomes for malignant peritoneal mesothelioma treated at academic compared to community facilities. Patients at academic centers underwent surgery and received chemotherapy on the same day as surgery more frequently than those at community centers, suggesting that malignant peritoneal mesothelioma patients may be better served at experienced academic centers.
