Problem: Chronic rhinosinusitis (CRS) is a heterogeneous disease with an uncertain pathogenesis. Group 2 innate lymphoid cells (ILC2s) represent a recently discovered cell population which has been implicated in driving Th2 inflammation in CRS; however, their relationship with clinical disease characteristics has yet to be investigated. The aim of this study was to identify ILC2s in sinus mucosa in patients with CRS and controls and compare ILC2s across characteristics of disease. A cross-sectional study of patients with CRS undergoing endoscopic sinus surgery was conducted. Sinus mucosal biopsies were obtained during surgery and control tissue from patients undergoing pituitary tumour resection through transphenoidal approach. ILC2s were identified as CD45(+) Lin(-) CD127(+) CD4(-) CD8(-) CRTH2(CD294)(+) CD161(+) cells in single cell suspensions through flow cytometry. ILC2 frequencies, measured as a percentage of CD45(+) cells, were compared across CRS phenotype, endotype, inflammatory CRS subtype and other disease characteristics including blood eosinophils, serum IgE, asthma status and nasal symptom score. 35 patients (40% female, age 48 17 years) including 13 with eosinophilic CRS (eCRS), 13 with non-eCRS and 9 controls were recruited. ILC2 frequencies were associated with the presence of nasal polyps (P = 0.002) as well as high tissue eosinophilia (P = 0.004) and eosinophil-dominant CRS (P = 0.001) (Mann-Whitney U). They were also associated with increased blood eosinophilia (P = 0.005). There were no significant associations found between ILC2s and serum total IgE and allergic disease. In the CRS with nasal polyps (CRSwNP) population, ILC2s were increased in patients with co-existing asthma (P = 0.03). ILC2s were also correlated with worsening nasal symptom score in CRS (P = 0.04).

Explanation: There is a line in the passage which say 'The aim of this study was...' which suggests that it is talking about a specific aim. Hence, the output should be 1 as this passage has a definite aim.

Problem: Early safe discharge is paramount for the success of ERAS following colorectal cancer resections. Anastomotic leakage (AL) has high morbidity, particularly if the patient has been discharged to the community.', 'To evaluate whether C-reactive protein (CRP) and procalcitonin (PCT) can predict AL before early discharge.', 'Fifty-five consecutive patients undergoing open and robotic colorectal cancer resections were included. C-reactive protein and PCT were measured pre-operatively, 8 h after incision, and on the first and third postoperative day. Thirty-day readmissions, re-operations and mortality were recorded.', 'Twenty-nine patients underwent robotic and the remainder open (n = 26) resections. Five patients had AL. The mean CRP and PCT increased on postoperative day 1 (POD 1) and POD 3 in all patients. On POD 3, mean CRP was 114 mg/l in non-AL patients and 321 mg/l in AL patients (p = 0.0001). Mean PCT on POD 3 was 0.56 ng/ml in the non-AL group and 10.4 ng/ml in AL patients (p = 0.017). On analysis of ROC and AUC curves, the cut-off for CRP on POD 3 was 245.64 mg/l, with 100% sensitivity and 98% specificity for AL. The cut-off for PCT on POD 3 was 3.83 ng/ml, with 75% sensitivity and 100% specificity for AL.
