Background Ileus is common after elective colorectal surgery, and is associated with increased adverse events and prolonged hospital stay. The aim was to assess the role of non‐steroidal anti‐inflammatory drugs (NSAIDs) for reducing ileus after surgery. Methods A prospective multicentre cohort study was delivered by an international, student‐ and trainee‐led collaborative group. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The primary outcome was time to gastrointestinal recovery, measured using a composite measure of bowel function and tolerance to oral intake. The impact of NSAIDs was explored using Cox regression analyses, including the results of a centre‐specific survey of compliance to enhanced recovery principles. Secondary safety outcomes included anastomotic leak rate and acute kidney injury. Results A total of 4164 patients were included, with a median age of 68 (i.q.r. 57–75) years (54·9 per cent men). Some 1153 (27·7 per cent) received NSAIDs on postoperative days 1–3, of whom 1061 (92·0 per cent) received non‐selective cyclo‐oxygenase inhibitors. After adjustment for baseline differences, the mean time to gastrointestinal recovery did not differ significantly between patients who received NSAIDs and those who did not (4·6 versus 4·8 days; hazard ratio 1·04, 95 per cent c.i. 0·96 to 1·12; P = 0·360). There were no significant differences in anastomotic leak rate (5·4 versus 4·6 per cent; P = 0·349) or acute kidney injury (14·3 versus 13·8 per cent; P = 0·666) between the groups. Significantly fewer patients receiving NSAIDs required strong opioid analgesia (35·3 versus 56·7 per cent; P < 0·001). Conclusion NSAIDs did not reduce the time for gastrointestinal recovery after colorectal surgery, but they were safe and associated with reduced postoperative opioid requirement.

Background: Alopecia is a common and distressing adverse effect in breast cancer (BC) patients (pts) receiving adjuvant chemotherapy. The aim of the study was to assess the effectiveness and safety of this device to prevent chemotherapy-induced alopecia in early breast cancer patients (EBCP) receiving adjuvant treatment. The quality of life of pts was also evaluated. Patients and methods: From January to December 2016, a sensor-controlled scalp cooling system (DigniCap:Sysmex Europe GmbH, Norderstedt, Germany) was proposed to a consecutive group of EBCP submitted to adjuvant chemotherapy at the Breast Unit of Spedali Civili Hospital of Brescia. Degree of hair loss was assessed by two nurse using Dean's alopecia scale by digital photographs at baseline and each chemotherapy cycle. EORTC QLQ-C30 questionnaire and self-reported visual analogical scale (VAS) of symptoms (anxiety, tone of mood, fatigue, nausea,well-being, activity) were collected at baseline and after the first two cycles of chemotherapy. Results: 70 pts were enrolled and 49 (70%) completed the chemotherapy plan and were evaluable. Median age was 51 years, 8 pts (16%) received neoadjuvant and 41 pts (84%) adjuvant chemotherapy, 21 (43%) were treated with 4 cycle of chemotherapy (TC, EC or paclitaxel alone), and 28 (57%) with sequential chemotherapy with antracycline and taxane +- trastuzumab. Fifteen pts (30%) stopped the treatment because of loss of hair in 9 pts, for headache in 4 pts and for other problems in 2 pts. At the end of chemotherapy, 13 pts (27%) had no loss of hair (Dean score 0), 25 pts (51%) had a minimal loss of hair (Dean score 1), 9 pts (18%) had a 50% hair loss (Dean score 2), 2 pts (4%) had a 75% hair loss (Dean score 3). No pts reported hair loss more than 75% (Dean score 4). There wasn't a significant difference between mean score value of QLQ-C30 at baseline and after chemotherapy and between the groups with and without hair loss. VAS documented an increase of fatigue and decrease of anxiety from baseline to final evaluation. The side effects presented with the use of DigniCap were the following: headache in 32% of pts and cold feeling in 57 % of pts. Conclusion: Scalp cooling with cold caps appears to be effective in preventing CIA among the majority of women undergoing treatment chemotherapy. The quality of life did not change in scalp-cooled patients. Acknowledgments: a thank you to the ESA association that donated Dignicap to Oncology Department.

Background Postoperative acute kidney injury (AKI) is a common complication of major gastrointestinal surgery with an impact on short- and long-term survival. No validated system for risk stratification exists for this patient group. This study aimed to validate externally a prognostic model for AKI after major gastrointestinal surgery in two multicentre cohort studies. Methods The Outcomes After Kidney injury in Surgery (OAKS) prognostic model was developed to predict risk of AKI in the 7 days after surgery using six routine datapoints (age, sex, ASA grade, preoperative estimated glomerular filtration rate, planned open surgery and preoperative use of either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker). Validation was performed within two independent cohorts: a prospective multicentre, international study (‘IMAGINE’) of patients undergoing elective colorectal surgery (2018); and a retrospective regional cohort study (‘Tayside’) in major abdominal surgery (2011–2015). Multivariable logistic regression was used to predict risk of AKI, with multiple imputation used to account for data missing at random. Prognostic accuracy was assessed for patients at high risk (greater than 20 per cent) of postoperative AKI. Results In the validation cohorts, 12.9 per cent of patients (661 of 5106) in IMAGINE and 14.7 per cent (106 of 719 patients) in Tayside developed 7-day postoperative AKI. Using the OAKS model, 558 patients (9.6 per cent) were classified as high risk. Less than 10 per cent of patients classified as low-risk developed AKI in either cohort (negative predictive value greater than 0.9). Upon external validation, the OAKS model retained an area under the receiver operating characteristic (AUC) curve of range 0.655–0.681 (Tayside 95 per cent c.i. 0.596 to 0.714; IMAGINE 95 per cent c.i. 0.659 to 0.703), sensitivity values range 0.323–0.352 (IMAGINE 95 per cent c.i. 0.281 to 0.368; Tayside 95 per cent c.i. 0.253 to 0.461), and specificity range 0.881–0.890 (Tayside 95 per cent c.i. 0.853 to 0.905; IMAGINE 95 per cent c.i. 0.881 to 0.899). Conclusion The OAKS prognostic model can identify patients who are not at high risk of postoperative AKI after gastrointestinal surgery with high specificity.
