The DoMore-v1-CRC marker was recently developed using deep learning and conventional haematoxylin and eosin-stained tissue sections, and was observed to outperform established molecular and morphological markers of patient outcome after primary colorectal cancer resection. The aim of the present study was to develop a clinical decision support system based on DoMore-v1-CRC and pathological staging markers to facilitate individualised selection of adjuvant treatment. We estimated cancer-specific survival in subgroups formed by pathological tumour stage (pT<4 or pT4), pathological nodal stage (pN0, pN1, or pN2), number of lymph nodes sampled (≤12 or >12) if not pN2, and DoMore-v1-CRC classification (good, uncertain, or poor prognosis) in 997 patients with stage II or III colorectal cancer considered to have no residual tumour (R0) from two community-based cohorts in Norway and the UK, and used these data to define three risk groups. An external cohort of 1075 patients with stage II or III R0 colorectal cancer from the QUASAR 2 trial was used for validation; these patients were treated with single-agent capecitabine. The proposed risk stratification system was evaluated using Cox regression analysis. We similarly evaluated a risk stratification system intended to reflect current guidelines and clinical practice. The primary outcome was cancer-specific survival. The new risk stratification system provided a hazard ratio of 10·71 (95% CI 6·39–17·93; p<0·0001) for high-risk versus low-risk patients and 3·06 (1·73–5·42; p=0·0001) for intermediate versus low risk in the primary analysis of the validation cohort. Estimated 3-year cancer-specific survival was 97·2% (95% CI 95·1–98·4; n=445 [41%]) for the low-risk group, 94·8% (91·7–96·7; n=339 [32%]) for the intermediate-risk group, and 77·6% (72·1–82·1; n=291 [27%]) for the high-risk group. The guideline-based risk grouping was observed to be less prognostic and informative (the low-risk group comprised only 142 [13%] of the 1075 patients). Integrating DoMore-v1-CRC and pathological staging markers provided a clinical decision support system that risk stratifies more accurately than its constituent elements, and identifies substantially more patients with stage II and III colorectal cancer with similarly good prognosis as the low-risk group in current guidelines. Avoiding adjuvant chemotherapy in these patients might be safe, and could reduce morbidity, mortality, and treatment costs. The Research Council of Norway.

Background Gastrointestinal (GI) dysfunction is frequent in the critically ill but can be overlooked as a result of the lack of standardization of the diagnostic and therapeutic approaches. We aimed to develop a research agenda for GI dysfunction for future research. We systematically reviewed the current knowledge on a broad range of subtopics from a specific viewpoint of GI dysfunction, highlighting the remaining areas of uncertainty and suggesting future studies. Methods This systematic scoping review and research agenda was conducted following successive steps: (1) identify clinically important subtopics within the field of GI function which warrant further research; (2) systematically review the literature for each subtopic using PubMed, CENTRAL and Cochrane Database of Systematic Reviews; (3) summarize evidence for each subtopic; (4) identify areas of uncertainty; (5) formulate and refine study proposals that address these subtopics; and (6) prioritize study proposals via sequential voting rounds. Results Five major themes were identified: (1) monitoring, (2) associations between GI function and outcome, (3) GI function and nutrition, (4) management of GI dysfunction and (5) pathophysiological mechanisms. Searches on 17 subtopics were performed and evidence summarized. Several areas of uncertainty were identified, six of them needing consensus process. Study proposals ranked among the first ten included: prevention and management of diarrhoea; management of upper and lower feeding intolerance, including indications for post-pyloric feeding and opioid antagonists; acute gastrointestinal injury grading as a bedside tool; the role of intra-abdominal hypertension in the development and monitoring of GI dysfunction and in the development of non-occlusive mesenteric ischaemia; and the effect of proton pump inhibitors on the microbiome in critical illness. Conclusions Current evidence on GI dysfunction is scarce, partially due to the lack of precise definitions. The use of core sets of monitoring and outcomes are required to improve the consistency of future studies. We propose several areas for consensus process and outline future study projects.

Background: Modern epidemiology increasingly uses data on families. The authors constructed an extended fertility database for women born in Denmark from 1930 onwards by supplementing the existing Fertility Database with household data from the 1970 census. Methods: A fertility history was constructed for all women participating in the 1970 census, but aiming for complete data only for women aged 20 - 39. The fertility history of these women prior to the 1970 census was constructed from the census data including 1,648,813 persons coded as children. An algorithm was used transforming household information into fertility history data by matching women and children according to family position. Children for whom the algorithm gave no match were searched for in the Fertility Database; children not found in the Fertility Database either were searched for manually. The fertility history after the 1970 census was retrieved from the Fertility Database. Results: Using data from the census 1970, 98.5% of the children were linked to a mother, and 99.6% of these links were estimated to be correct, corresponding to 98.1% of the children being linked correctly. In total, 964,720 children of women aged 20 - 39 in 1970 were identified, which was equivalent to 96.6% of the expected live-born children, and to 99.1% of the expected surviving children. Conclusion: Census household data proved to be an excellent data source for construction of fertility histories.

Patient compliance is of vital importance for the outcome of any medical therapy. Compliance is especially a problem in long-term treatment of non-life threatening diseases, such as growth retardation in children. Until recently, all human growth hormone (hGH) products required a reconstitution process. Norditropin((R)) SimpleXx(TM) is a liquid formulation of the biosynthetic hGH product Norditropin((R)), and, together with an improved NovoPen((R)) 1.5, NordiPen(TM), and an auto-insertion device, PenMate(TM)/NordiPenMate(TM), it has been developed in order to ease the injection process for patients. A randomized, open, multicentre, crossover trial compared Norditropin((R)) SimpleXx(TM)/improved NovoPen((R)) 1.5 with freeze-dried Norditropin((R)) PenSet((R))/Nordiject((R)). A total of 67 children with GH deficiency, aged 5-18 years, were treated with either Norditropin((R)) SimpleXx(TM) for 6 weeks followed by Norditropin((R)) for 6 weeks or the opposite (sequences I and II, respectively). Acceptability/convenience and pain perception were evaluated by questionnaire after each period. The function and handling of the PenMate(TM) were evaluated in a Dutch trial by 27 GH-treated children with intrauterine growth retardation, aged 4-16 years, and their parents. All children were accustomed to using the Nordiject((R)) pen. The evaluation of the PenMate(TM) was based on a questionnaire. A similar trial was conducted in England, in which the NordiPen(TM) and the NordiPenMate(TM) were evaluated by 25 GH-treated children and their parents. Norditropin((R)) SimpleXx(TM) was found to be easier to inject by 64% of the children, and 98% of the children found the system easier to use overall. There was no difference in pain perception between the two administration systems, as judged by questionnaires and visual analogue scale score. Three out of four patients preferred to continue treatment with Norditropin((R)) SimpleXx(TM). The safety profiles of the two systems were similar. In the Dutch trial, the PenMate(TM) was found to be easy and safe to handle, even for very young children (aged 4-5 years). Of patients who took a long time to get used to the injections, 73% found that the new pen would help. A total of 88% of the children would prefer to use the PenMate(TM) in the future. Positive results of the handling tests were also reported in the British trial. The use of Norditropin((R)) SimpleXx(TM) and the auto-insertion device may improve patient compliance.
