Surgical oncology during the post-COVID-19 era: What is next?

During first outburst of COVID-19, several strategies had been applied for surgical oncology patients to minimize COVID-19 transmission. COVID-19 infection seemed to compromise survival and major complication rates of surgical oncology patients. However, survival, tumor progression and recurrence rates of surgical oncology patients were associated to the consequences of COVID-19 pandemic on their management. In addition, the severity of COVID-19 infections has been downgraded. Therefore, management of surgical oncology patients should be reconsidered.     

Audiovisual integration and the P2 component in adult Asperger’s syndrome: An ERP-study

BackgroundA widened temporal window of integration (TWI) in audiovisual processing has been detected for children with autism spectrum disorder. However, research indicates a narrowing of this TWI and an associated change in audiovisual integration in the course of development.MethodsTo further elucidate audiovisual integration processes in adulthood, we compared adult participants with Asperger’s Syndrome (AS) to healthy controls (HC) by using the sound-induced double flash illusion. For a better understanding of underlying neural mechanisms, event-related potentials were measured via electroencephalography (EEG).ResultsThe number of reported sound-induced flash illusions indicated audiovisual integration. A similar TWI size for both, participants with AS and HC, was found. Additionally, enhanced P2 amplitudes were detected for participants with AS compared to HC.ConclusionResults indicate an involvement of attentional processes in audiovisual perception in participants with AS.     

Quality indicators for breast cancer care: A systematic review

ObjectivesWe evaluated breast cancer (BC) care quality indicators (QIs) in clinical pathways and integrated health care processes.MethodsFollowing protocol registration (Prospero n^o: CRD42021228867), relevant documents were identified, without language restrictions, through a systematic search of bibliographic databases (EMBASE, Scopus, Web of Science, MEDLINE), health care valuable representatives and the World Wide Web in April 2021. Data concerning QIs, measurement tools and compliance standards were extracted from European and North American sources in duplicate with 98% reviewer agreement.ResultsThere were 89 QIs found from 22 selected documents (QI per document mean 13.5 with standard deviation 11.9). The Belgian (38 QIs) and the EUSOMA (European Society of Breast Cancer Specialists) (34 QIs) documents were the ones that best reported the QIs. No identical QI was identified in all the documents analysed. There were 67/89 QIs covering processes (75.3%) and 11/89 (12.4%) for each structure and outcomes QIs. There were 21/89 QIs for diagnosis (30.3%), 43/89 for treatment (48.3%), and 19/89 for staging, counselling, follow-up and rehabilitation (21.4%). Of 67 process QIs and 11 outcome QIs, 20/78 (26%) did not report a minimum standard of care. Shared decision making was only included as a QI in the Italian document.ConclusionMore than half of countries have not established a national clinical pathway or integrated breast cancer care process to achieve the excellence of BC care. There was heterogeneity in QIs for the evaluation of BC care quality. Over two-thirds of the clinical pathways and integrated health care processes did not provide a minimum auditable standard of care for compliance, leaving open the definition of best practice. There is a need for harmonisation of BC care QIs.

China special issue on gastrointestinal tumors-Improved survival after multidisciplinary team decision for patients with advanced gastrointestinal cancer: A multicenter,noninterventional, controlled study

Formal multidisciplinary team (MDT) discussions in clinical practice require time and space but have unclear survival benefits for advanced gastrointestinal cancer patients. Our study aimed to investigate the long-term survival of patients with advanced gastrointestinal cancer after MDT decision. From June 2017 to June 2019, continuous MDT discussions on advanced gastrointestinal cancer were conducted in 13 medical centers in China. MDT decisions and actual treatment received by patients were prospectively recorded. The primary endpoint was the difference in overall survival (OS) between patients in the MDT decision implementation and nonimplementation groups. The secondary endpoints included the implementation rate of MDT decisions and subgroup survival analysis. A total of 461 MDT decisions of 455 patients were included in our study. The implementation rate of MDT decisions was 85.7%. Previous treatment had an impact on MDT decision-making. The OS was 24.0 months and 17.0 months in the implementation and nonimplementation groups, respectively. The implementation of MDT decisions significantly reduced the risk of death in multivariate analyses (hazard ratio = 0.518; 95% confidence interval: 0.304-0.884, P = .016). Subgroup analysis showed a significant difference in survival of patients with colorectal cancer, but not in survival of patients with gastric cancer. The rate of secondary MDT discussion was only 5.6% among patients who the MDT decisions were discontinued due to changes in their condition. MDT discussion can prolong the OS of patients with advanced gastrointestinal cancer, especially those with colorectal cancer. Timely scheduling of the subsequent MDT discussion is necessary when the disease condition changes.

Amyotrophic lateral sclerosis presenting as the temporomandibular disorder: A case report and literature review

Background: Spasticity and pain in the masticatory muscles or mouth opening limitation have been reported as early signs and symptoms of amyotrophic lateral sclerosis (ALS). These signs and symptoms are also frequently seen in, and thus mistaken for, temporomandibular disorders (TMD).

Clinical presentation: The authors report a case of ALS initially presenting with signs and symptoms of TMD. The TMD was followed by dysarthria of insidious onset, leading to the diagnosis of ALS. This case highlights the importance of considering TMD as a potential early form of presentation of ALS, requiring multidisciplinary treatment, especially by dental professionals.

Conclusion: A review of the literature was conducted to elucidate the oral and facial signs and symptoms of ALS and to identify ways of improving the quality of life of patients through a multidisciplinary approach.     

Temporal integration as “common currency” of brain and self‐scale‐free activity in resting‐state EEG correlates with temporal delay effects on self‐relatedness

The self is a multifaceted phenomenon that integrates information and experience across multiple time scales. How temporal integration on the psychological level of the self is related to temporal integration on the neuronal level remains unclear. To investigate temporal integration on the psychological level, we modified a well‐established self‐matching paradigm by inserting temporal delays. On the neuronal level, we indexed temporal integration in resting‐state EEG by two related measures of scale‐free dynamics, the power law exponent and autocorrelation window. We hypothesized that the previously established self‐prioritization effect, measured as decreased response times or increased accuracy for self‐related stimuli, would change with the insertion of different temporal delays between the paired stimuli, and that these changes would be related to temporal integration on the neuronal level. We found a significant self‐prioritization effect on accuracy in all conditions with delays, indicating stronger temporal integration of self‐related stimuli. Further, we observed a relationship between temporal integration on psychological and neuronal levels: higher degrees of neuronal integration, that is, higher power‐law exponent and longer autocorrelation window, during resting‐state EEG were related to a stronger increase in the self‐prioritization effect across longer temporal delays. We conclude that temporal integration on the neuronal level serves as a template for temporal integration of the self on the psychological level. Temporal integration can thus be conceived as the “common currency” of neuronal and psychological levels of self.
