- An organizing structure that in recent years has had a major impact on how to work with students who don’t respond to regular instruction is Response to Intervention (RTI). Efforts in RTI are divided into three different tiers of instruction: primary, secondary and tertiary. In our study, we investigate the impact of intensive secondary-tier instruction on students’ knowledge of basic combinations of digits in addition. We also focus on how the students develop their use of more advanced calculations in addition during the intervention.The results showed that students became faster at performing simple addition tasks, which indicates that their fluency – declarative knowledge – developed during the intervention phase. Our results thereby strengthen suggestions that a secondary-tier intervention level should take place in a small group of students 20-40 minutes four to five times a week. Meanwhile, the students developed their ability to solve two-digit arithmetic tasks in addition and subtraction, which could be explained by the fact that students had automated simple number combinations and thus could focus on the calculation procedure.

- INTRODUCTION: A significant proportion of patients suffer depression following traumatic injuries. Once manifested, major depression is challenging to overcome and its presence risks impairing the potential for physical rehabilitation and functional recovery. Risk stratification for early detection and intervention in these instances is important. This study aims to investigate patient and injury characteristics associated with an increased risk for depression.METHODS: All patients with traumatic injuries were recruited from the trauma registry of an urban university hospital between 2007 and 2012. Patient and injury characteristics as well as outcomes were collected for analysis. Patients under the age of eighteen, prescribed antidepressants within one year of admission, in-hospital deaths and deaths within 30days of trauma were excluded. Pre- and post-admission antidepressant data was requested from the national drugs registry. Post-traumatic depression was defined as the prescription of antidepressants within one year of trauma. To isolate independent risk factors for depression a multivariable forward stepwise logistic regression model was deployed.RESULTS: A total of 5981 patients met the inclusion criteria of whom 9.2% (n=551) developed post-traumatic depression. The mean age of the cohort was 42 [standard deviation (SD) 18] years and 27.1% (n=1620) were females. The mean injury severity score was 9 (SD 9) with 18.4% (n=1100) of the patients assigned a score of at least 16. Six variables were identified as independent predictors for post-traumatic depression. Factors relating to the patient were female gender and age. Injury-specific variables were penetrating trauma and GCS score of≤8 on admission. Furthermore, intensive care admission and increasing hospital length of stay were predictors of depression.CONCLUSION: Several risk factors associated with the development of post-traumatic depression were identified. A better targeted in-hospital screening and patient-centered follow up can be offered taking these risk factors into consideration.

- OBJECTIVE: To ascertain whether regular β-blocker exposure can improve short- and long-term outcomes after rectal cancer surgery.BACKGROUND: Surgery for rectal cancer is associated with substantial morbidity and mortality. There is increasing evidence to suggest that there is a survival benefit in patients exposed to β-blockers undergoing non-cardiac surgery. Studies investigating the effects on outcomes in patients subjected to surgery for rectal cancer are lacking.METHODS: All adult patients undergoing elective abdominal resection for rectal cancer over a 10-year period were recruited from the prospectively collected Swedish Colorectal Cancer Registry. Patients were subdivided according to preoperative β-blocker exposure status. Outcomes of interest were 30-day complications, 30-day cause-specific mortality, and 1-year all-cause mortality. The association between β-blocker use and outcomes were analyzed using Poisson regression model with robust standard errors for 30-day complications and cause-specific mortality. One-year survival was assessed using Cox proportional hazards regression model.RESULTS: A total of 11,966 patients were included in the current study, of whom 3513 (29.36%) were exposed to regular preoperative β-blockers. A significant decrease in 30-day mortality was detected (incidence rate ratio = 0.06, 95% confidence interval: 0.03-0.13, P < 0.001). Deaths of cardiovascular nature, respiratory origin, sepsis, and multiorgan failure were significantly lower in β-blocker users, as were the incidences in postoperative infection and anastomotic failure. The β-blocker positive group had significantly better survival up to 1 year postoperatively with a risk reduction of 57% (hazard ratio = 0.43, 95% confidence interval: 0.37-0.52, P < 0.001).CONCLUSIONS: Preoperative β-blocker use is strongly associated with improved survival and morbidity after abdominal resection for rectal cancer.

Journal article (peer-reviewed)abstract
- BACKGROUND: Anorectal function after rectal surgery with low anastomosis is often impaired. Outcome of long-term anorectal function is poorly understood but may improve over time.OBJECTIVE: We evaluated anorectal function 5 years after low anterior resection for cancer with regard to whether patients had a temporary stoma at initial resection. The objective of this study was to assess changes in anorectal function over time by comparing the results with anorectal function 1 year after rectal resection.DESIGN: This study was a secondary end point of a randomized, multicenter controlled trial.SETTINGS: The study was conducted at 21 Swedish hospitals performing rectal cancer surgery from 1999 to 2005.PATIENTS: Patients included were those operated on with low anterior resection.INTERVENTIONS: Patients were randomly assigned to receive or not receive a defunctioning stoma.MAIN OUTCOME MEASURES: We evaluated anorectal function in patients who were initially randomly assigned to the defunctioning stoma or no stoma group, who had been free of stoma for 5 years, by means of using a standardized patient questionnaire. Questions addressed stool frequency, urgency, fragmentation of bowel movements, evacuation difficulties, incontinence, lifestyle alterations, and patient preference regarding permanent stoma formation. Results were compared with the same patient cohort at 1-year follow-up.RESULTS: A total of 123 patients answered the bowel function questionnaire (65 in the no-stoma group and 58 in the stoma group). No differences were found between groups regarding the number of passed stools, need for medication to open the bowel, evacuation difficulties, incontinence, and urgency. General well-being was significantly better in the no-stoma group (p = 0.033). Comparison with anorectal function at 1 year showed no further changes over time.LIMITATIONS: The study was based on a limited sample size (n = 123) and formed a secondary end point of a randomized trial.CONCLUSIONS: Anorectal function was impaired for many patients, but the temporary presence of a defunctioning stoma after rectal resection did not affect long-term outcome. Anorectal function did not change between 1-year and 5-year follow-up.

Journal article (peer-reviewed)abstract
- Background and Aims: This study assessed the timing of reversal of defunctioning stoma following low anterior resection of the rectum for cancer and risk factors for a defunctioning stoma becoming permanent in patients who were not reversed.Material and Methods: Patients who underwent low anterior resection with defunctioning stoma during a 12-year period were assessed with regard to timing of stoma reversal. Delayed reversal was defined as > 4 months after low anterior resection. Patients with a defunctioning stoma that was never reversed were assessed regarding risk factors for permanent stoma.Results: A total of 134 patients were analyzed. Of 106 stoma reversals, 19% were reversed within 4 months of low anterior resection, while 81% were reversed later than 4 months. In 58% of these patients, the delay was to due to low medical priority given to this procedure. The other main reasons for delayed stoma reversal were nonsurgical complications (20%), symptomatic anastomotic leakage following low anterior resection (12%), and postoperative adjuvant chemotherapy (10%). Of all patients, 21% (28/134) ended up with a permanent stoma. Risk factors for a defunctioning stoma becoming permanent were stage IV cancer (P < 0.001) and symptomatic anastomotic leakage following low anterior resection (P < 0.001).Conclusion: Four in five patients experienced a delayed stoma reversal, in a majority because of the low priority given to this surgical procedure.

Journal article (peer-reviewed)abstract
- BACKGROUND: Anorectal function after low anterior resection of the rectum for cancer is often impaired, and long-term outcome has not frequently been reported.OBJECTIVE: We evaluated anorectal function 12 years after rectal resection with regard to whether patients had a defunctioning temporary stoma at the initial rectal resection.DESIGN: An exploratory cross-sectional investigation of a previously randomized study population.SETTINGS: Twenty-one Swedish hospitals performing rectal cancer surgery during a 5-year period participated in the trial.PATIENTS: Patients operated on with low anterior resection for cancer were included.INTERVENTIONS: Patients were randomly assigned to receive or not receive a temporary defunctioning stoma.MAIN OUTCOME MEASURES: We evaluated anorectal function 12 years after low anterior resection in patients who were initially randomly assigned to temporary stoma or not, by means of using the low anterior resection syndrome score questionnaire, which assesses incontinence for flatus, incontinence for liquid stools, defecation frequency, clustering, and urgency. Self-perceived health status was evaluated by the EQ-5D-3L questionnaire.RESULTS: Eighty-nine percent (87/ 98) of the patients responded to the questionnaires, including 46 with and 41 without an initial temporary stoma. Patient demography was comparable between the groups. No differences regarding major, minor, and no low anterior resection syndrome categories were found between the groups. The stoma group had increased incontinence for flatus (p = 0.03) and liquid stools (p = 0.005) and worse overall low anterior resection syndrome score (p = 0.04) but no differences regarding frequency, clustering, and urgency.LIMITATIONS: The study was limited by its sample size (n = 98) based on a previously randomized trial population (n = 234).CONCLUSIONS: After low anterior resection for cancer, the incidence of the categories major, minor, and no low anterior resection syndrome were comparable in the stoma and the no-stoma groups. Incontinence for flatus and liquid stools was more commonly reported by patients who were randomly assigned to temporary stoma, as compared with those without, which may indicate an association between temporary stoma and impaired anorectal function.

Journal article (peer-reviewed)abstract
- BACKGROUND: The aim was to assess factors influencing the timing of defunctioning stoma (DS) reversal following low anterior resection of rectum for cancer (LAR).METHODS: All patients operated with LAR and a primary DS during a 9-year period were included. Reversal later than 120 days after LAR was considered as delayed. A DS not reversed within 2 years was considered as permanent.RESULTS: In the present study, median age at LAR was 67 years, 45% were females, median body mass index was 25, 87% had American Society of Anesthesiologists class I or II, 64% had pre-operative radiotherapy, and 3% had cancer stage IV. A total of 79% (92/116) underwent stoma reversal, whereof 25% (23/92) were reversed within 120 days. The most common health-related reasons for delayed stoma reversal were adjuvant chemotherapy in 38%, symptomatic anastomotic leakage in 16% and other post-operative adverse events in 13%. In 35% delayed stoma reversal was because of low priority within the healthcare system. A total of 18% (20/110) never had their DS reversed (n = 11) or had their DS converted to a permanent end colostomy (n = 9). Major risk factors for permanent stoma were stage IV cancer in 55%, and symptomatic anastomotic leakage in 30%.CONCLUSION: One fourth of the patients had their defunctioning stoma reversed within 120 days. The most common identifiable medical reasons for delayed stoma reversal were adjuvant chemotherapy and symptomatic anastomotic leakage, while in one out of three patients it was because of low priority by the healthcare provider.
