Surgical treatment of stage IV colorectal cancer with synchronous liver metastases : a systematic review and network meta-analysis

Background: The ideal treatment approach for colorectal cancer (CRC) with synchronous liver metastases (SCRLM) remains debated. We performed a network meta-analysis (NMA) comparing the 'bowel-first' approach (BFA), simultaneous resection (SIM), and the 'liver-first' approach (LFA). Methods: A systematic search of comparative studies in CRC with SCRLM was undertaken using the Embase, PubMed, Web of Science, and CENTRAL databases. Outcome measures included postoperative complications, 30- and 90-day mortality, chemotherapy use, treatment completion rate, 3- and 5-year recurrence-free survival, and 3- and 5-year overall survival (OS). Pairwise and network meta-analysis were performed to compare strategies. Heterogeneity was assessed using the Higgins I-2 statistic. Results: One prospective and 43 retrospective studies reporting on 10 848 patients were included. Patients undergoing the LFA were more likely to have rectal primaries and a higher metastatic load. The SIM approach resulted in a higher risk of major morbidity and 30-day mortality. Compared to the BFA, the LFA more frequently resulted in failure to complete treatment as planned (34% versus 6%). Pairwise and network meta-analysis showed a similar 5-year OS between LFA and BFA and a more favorable 5-year OS after SIM compared to LFA (odds ratio 0.25-0.90, p = 0.02, I-2 = 0%), but not compared to BFA. Conclusion: Despite a higher tumor load in LFA compared to BFA patients, survival was similar. A lower rate of treatment completion was observed with LFA. Uncertainty remains substantial due to imprecise estimates of treatment effects. In the absence of prospective trials, treatment of stage IV CRC patients should be individually tailored.

The connection between antisocial creativity and values of students of pedagogical specialties

Scholars study various aspects of creativity: features of a creative personality; the impact of creativity on society; mechanisms and conditions for the development of creativity. Creativity is productive, makes the life of a person and society better, as well as promotes progress. At the same time, the phenomenon of creativity is not so definite since scholars distinguish such a variety as antisocial creativity, in which a person uses one’s creative potential against society and other people. This is reflected in specific research concerned with this phenomenon. It emphasizes the negative influence of the antisocial creativity of teachers on the forming personality of students and the effectiveness of education. The study objective is to study the antisocial creativity of future teachers and its connection with values and basic beliefs. The methods of testing, polling, mathematical statistics (correlation analysis) were used in the course of the study. This empirical study has revealed strong links between antisocial creativity and the age of respondents. As a result, antisocial creativity is connected with such values of social groups as conformism, tradition (inverse correlation); self-direction, power and achievement (direct correlation). A negative correlation with the humor scale allows the authors to conclude that this type of antisocial creativity is a kind of defense. For the first time, this ascertaining study has considered the specifics of antisocial creativity of students of pedagogical specialties with due regard to their beliefs and values. The promising areas of research on the antisocial creativity of future teachers include identifying both personal and social determinants of this phenomenon

Incidence of severe critical events in paediatric anaesthesia (APRICOT): a prospective multicentre observational study in 261 hospitals in Europe

Background Little is known about the incidence of severe critical events in children undergoing general anaesthesia in Europe. We aimed to identify the incidence, nature, and outcome of severe critical events in children undergoing anaesthesia, and the associated potential risk factors. Methods The APRICOT study was a prospective observational multicentre cohort study of children from birth to 15 years of age undergoing elective or urgent anaesthesia for diagnostic or surgical procedures. Children were eligible for inclusion during a 2-week period determined prospectively by each centre. There were 261 participating centres across 33 European countries. The primary endpoint was the occurence of perioperative severe critical events requiring immediate intervention. A severe critical event was defined as the occurrence of respiratory, cardiac, allergic, or neurological complications requiring immediate intervention and that led (or could have led) to major disability or death. This study is registered with ClinicalTrials.gov, number NCT01878760. Findings Between April 1, 2014, and Jan 31, 2015, 31â127 anaesthetic procedures in 30â874 children with a mean age of 6·35 years (SD 4·50) were included. The incidence of perioperative severe critical events was 5·2% (95% CI 5·0â5·5) with an incidence of respiratory critical events of 3·1% (2·9â3·3). Cardiovascular instability occurred in 1·9% (1·7â2·1), with an immediate poor outcome in 5·4% (3·7â7·5) of these cases. The all-cause 30-day in-hospital mortality rate was 10 in 10â000. This was independent of type of anaesthesia. Age (relative risk 0·88, 95% CI 0·86â0·90; p<0·0001), medical history, and physical condition (1·60, 1·40â1·82; p<0·0001) were the major risk factors for a serious critical event. Multivariate analysis revealed evidence for the beneficial effect of years of experience of the most senior anaesthesia team member (0·99, 0·981â0·997; p<0·0048 for respiratory critical events, and 0·98, 0·97â0·99; p=0·0039 for cardiovascular critical events), rather than the type of health institution or providers. Interpretation This study highlights a relatively high rate of severe critical events during the anaesthesia management of children for surgical or diagnostic procedures in Europe, and a large variability in the practice of paediatric anaesthesia. These findings are substantial enough to warrant attention from national, regional, and specialist societies to target education of anaesthesiologists and their teams and implement strategies for quality improvement in paediatric anaesthesia.
