AbstractThe preparatory accommodation response of lower esophageal sphincter (LES) before swallowing is one of the mechanisms involved in LES relaxation during wet swallows, however, the physiological and/or pathological roles of LES accommodation remain to be determined in humans. To address this problem, we conducted a prospective observational study of 38 patients with normal high-resolution manometry (HRM) and 23 patients with idiopathic esophagogastric junction outflow obstruction (EGJOO) to assess dry and wet swallows. The LES accommodation measurement was proposed for practical use in evaluating the LES accommodation response. Although swallow-induced LES relaxation was observed in both dry and wet swallows, LES accommodation (6.4, 3.1–11.1 mmHg) was only observed in wet swallows. The extent of LES accommodation was impaired in idiopathic EGJOO (0.6, − 0.6–6 mmHg), and the LES accommodation measurement of patients with idiopathic EGJOO (36.8, 29.5–44.3 mmHg) was significantly higher in comparison to those with normal HRM (23.8, 18–28.6 mmHg). Successful LES relaxation in wet swallowing can be achieved by LES accommodation in combination with swallow-induced LES relaxation. Impaired LES accommodation is characteristic of idiopathic EGJOO. In addition to the IRP value, the LES accommodation measurement may be useful for evaluating the LES relaxation function in clinical practice.

BACKGROUND: Despite evidence supporting the role of noninvasive ventilation (NIV) in diverse populations, few publications describe how NIV is used in clinical practice.OBJECTIVE: To describe NIV initiation in a teaching hospital that has a guideline, and to characterize temporal changes in NIV initiation over time.METHODS: A prospective, observational study of continuous positive airway pressure ventilation (CPAP) or bilevel NIV initiation from January 2000 to December 2005 was conducted. Registered respiratory therapists completed a one-page data collection form at NIV initiation.RESULTS: Over a six-year period, NIV was initiated in 623 unique patients (531 bilevel NIV, 92 CPAP). Compared with bilevel NIV, CPAP was initiated more often using a nasal interface, with a machine owned by the patient, and for chronic conditions, especially obstructive sleep apnea. Whereas CPAP was frequently initiated and continued on the wards, bilevel NIV was most frequently initiated and continued in the emergency department, intensive care unit and the coronary care unit. Patients initiated on bilevel NIV were more likely to be female (OR 1.8, 95% CI 1.08 to 2.85; P=0.02) and to have an acute indication compared with CPAP initiations (OR 7.5, 95% CI 1.61 to 34.41; P=0.01). Bilevel NIV was initiated more often in the emergency department than in the intensive care unit (OR 5.8, 95% CI 0.89 to 38.17; P=0.07). Bilevel NIV initiation increased from 2000 to 2005.CONCLUSIONS: The present study illustrates how NIV is used in clinical practice and confirms that NIV initiation has increased over time.

PurposeAdjuvant chemotherapy within 56 or 84 days following curative resection is globally accepted as the standard of care for stage III colon cancer as it has been associated with improved overall survival. Initiation of adjuvant chemotherapy within this time frame is therefore recommended by clinical practice guidelines, including the European Society for Medical Oncology. The objective of this study was to evaluate adherence to these clinical practice guidelines for patients with stage III colon cancer across the Rossy Cancer Network (RCN); a partnership of McGill University’s Faculty of Medicine, McGill University Health Centre, Jewish General Hospital and St Mary’s Hospital Center.Patients and methods187 patients who had been diagnosed with stage III colon cancer and received adjuvant chemotherapy within the RCN partner hospitals from 2012 to 2015 were included. Patient and treatment information was retrospectively determined by chart review. Χ2 and Wilcoxon rank-sum tests were used to measure associations and a multivariate Cox regression model was used to determine risk factors contributing to delays in administration of adjuvant chemotherapy.ResultsThe median turnaround time between surgery and adjuvant chemotherapy was 69 days. Importantly, only 27% of patients met the 56-day target, and 71% met the 84-day target. Increasing age, having more than one surgical complication and being diagnosed between 2013–2014 and 2014–2015 reduced the likelihood that patients met these targets. Furthermore, delays were observed at most intervals from surgery to first adjuvant chemotherapy treatment.ConclusionOur study found that within these academic hospital settings, 27% of patients met the 56-day target, and 71% met the 84-day target. Delays were associated with hospital, surgeon and patient-related factors. Initiatives in quality improvement are needed in order to improve adherence to recommended treatment guidelines for prompt administration of adjuvant chemotherapy for stage III colon cancer.

The Impact

478 Background: Colon cancer is predominantly a disease of the elderly, with recent evidence supporting the use of adjuvant chemotherapy in the older population. However, it remains unclear to what degree such patients are receiving adjuvant therapy in clinical practice. We examined uptake of adjuvantchemotherapy and it’s impact on survival in older patients with stage II and stage III colon cancer in a national cohort. Methods: Using the National cancer Registry of Ireland, we identified 3,486 patients with stage II and III colon cancer who were treated with curative resection from 2004-2009. Clinopathological features and chemotherapy use were compared between those ≥70 years and those < 70 years. Results: A total of 2,026 patients with stage II disease were identified, 56% male and 60% ≥ 70 years. T3 tumors accounted for 81%, T4 19% and 89% were grade 2/3. Adjuvant chemotherapy was utilized in 10% and 40% of ≥ 70 and <70 years, respectively (p<0.0001). A benefit for chemotherapy over observation alone was seen in both the older [HR 0.36; 95% CI 0.36 – 0.68; p <0.0001] and younger patient groups [HR 0.43; 95% CI 0.2701 - 0.6881; p<0.0004]. Of 1,460 patients with stage III disease, 51% were ≥ 70 years, 54% male. 34% of older and 83% of younger patients received adjuvant therapy (p<0.0001). A similar magnitude of benefit from chemotherapy compared to observation was seen in patients ≥ 70 years [HR 0.30; 95% CI 0.29 - 0.45 ; p <0.0001] and <70 years [HR 0.22 95%CI 0.1 – 0.2; p<0.0001] with stage III disease. Conclusions: Adoption of adjuvant chemotherapy appears to be associated with significant survival benefit in older patients (age ≥ 70 years), however, is still underutilized in clinical practice. The impact of sociodemographic and clinicopathological features as potential drivers of treatment decisions in a cohort of this population will be reported.
