Prefracture functional level evaluated by the New Mobility Score predicts in-hospital outcome after hip fracture surgery

BACKGROUND AND PURPOSE: Clinicians need valid and easily applicable predictors of outcome in patients with hip fracture. Adjusting for previously established predictors, we determined the predictive value of the New Mobility score (NMS) for in-hospital outcome in patients with hip fracture. PATIENTS AND METHODS: We studied 280 patients with a median age of 81 (interquartile range 72-86) years who were admitted from their own homes to a special hip fracture unit. Main outcome was the regain of independence in basic mobility, defined as. independence in getting in and out of bed, sitting down and standing up from a chair, and walking with an appropriate walking aid. The Cumulated Ambulation score was used to evaluate basic mobility. Predictor variables were NMS functional level before fracture, age, sex, fracture type, and mental and health status. RESULTS: Except for sex, all predictor variables were statistically significant in univariate testing. In multiple logistic regression analysis, only age, NMS functional level before fracture, and fracture type were significant. Thus, patients with a low prefracture NMS and/or an intertrochanteric fracture would be 18 and 4 times more likely not to regain independence in basic mobility during the hospital stay, respectively, than patients with a high prefracture level and a cervical fracture, respectively. The model was statistically stable and correctly classified 84% of cases. INTERPRETATION: The NMS functional level before fracture, age, and fracture type facilitate prediction of the in-hospital rehabilitation potential after hip fracture surgery

Contributions to the revision of the genus Entoloma (Basidiomycota, Agaricales) in Europe : six new species from subgenus Cyanula and typification of E. incarnatofuscescens

In anticipation of a phylogenetically revised monograph of Entoloma in Europe, six new species of subgenus Cyanula are described here. Entoloma cistocruentatum is associated with Cistus in Spain, E. dislocatum occurs in montane regions in Catalonia (Spain) and Tuscany (Italy), E. indikon is known from Denmark and three species are mainly distributed in the Nordic countries in Europe: E. calceus , E. perchalybeum and E. praecipuum. Entoloma incarnatofuscescens, from the /Rusticoides clade is neotypified. A fully amended description is given based on molecular evidence, which includes the recently described E. violaceoparkensis and E. klofacianum which became later synonyms.publishedVersio

After colonic surgery: The lived experience of participating in a fast-track programme

Postoperative recovery can be accelerated and hospitalization reduced through fast-track programmes. However, documented knowledge is limited and primarily focusing on a medical perspective whereas the patients' perspective lacks documentation. This study describes the lived experience of participating in a fast-track programme after colonic surgery. Sixteen patients were interviewed twice. The interviews were analysed using a descriptive phenomenological approach. Participating in a fast-track programme is characterized by a process where patients experience how the daily regimen works both with them and against them. To succeed in the overall goal of recovering fast according to the evidence-based care plan involves facing dilemmas and mobilizing courage and will to follow the regimen. Support from the professionals is crucial. The participants had a strong desire to comply and regain health; but this role of being a good and cooperative patient had a built-in asymmetric power relationship favouring the professionals' expectations. The complexities of this power relationship were related to both patient factors and contextual factors, e.g. the daily regimen and hospital norms. Although patient participation in care is an accepted ideal, it is demanding and difficult to accomplish. More studies on fast-track programmes are needed, with special attention to patient autonomy and partnership

Alvimopan for the Management of Postoperative Ileus After Bowel Resection: Characterization of Clinical Benefit by Pooled Responder Analysis

BACKGROUND: A pooled post hoc responder analysis was performed to assess the clinical benefit of alvimopan, a peripherally acting mu-opioid receptor (PAM-OR) antagonist, for the management of postoperative ileus after bowel resection. METHODS: Adult patients who underwent laparotomy for bowel resection scheduled for opioid-based intravenous patient-controlled analgesia received oral alvimopan or placebo preoperatively and twice daily postoperatively until hospital discharge or for 7 postoperative days. The proportion of responders and numbers needed to treat (NNT) were examined on postoperative days (POD) 3-8 for GI-2 recovery (first bowel movement, toleration of solid food) and hospital discharge order (DCO) written. RESULTS: Alvimopan significantly increased the proportion of patients with GI-2 recovery and DCO written by each POD (P \u3c 0.001 for all). More patients who received alvimopan achieved GI-2 recovery on or before POD 5 (alvimopan, 80%; placebo, 66%) and DCO written before POD 7 (alvimopan, 87%; placebo, 72%), with corresponding NNTs equal to 7. CONCLUSIONS: On each POD analyzed, alvimopan significantly increased the proportion of patients who achieved GI-2 recovery and DCO written versus placebo and was associated with relatively low NNTs. The results of these analyses provide additional characterization and support for the overall clinical benefit of alvimopan in patients undergoing bowel resection

Supportive interventions to improve physiological and psychological health outcomes among patients undergoing cystectomy: A systematic review

Background Our understanding of effective perioperative supportive interventions for patients undergoing cystectomy procedures and how these may affect short and long-term health outcomes is limited. Methods Randomised controlled trials involving any non-surgical, perioperative interventions designed to support or improve the patient experience for patients undergoing cystectomy procedures were reviewed. Comparison groups included those exposed to usual clinical care or standard procedure. Studies were excluded if they involved surgical procedure only, involved bowel preparation only or involved an alternative therapy such as aromatherapy. Any short and long-term outcomes reflecting the patient experience or related urological health outcomes were considered. Results 19 articles (representing 15 individual studies) were included for review. Heterogeneity in interventions and outcomes across studies meant meta-analyses were not possible. Participants were all patients with bladder cancer and interventions were delivered over different stages of the perioperative period. The overall quality of evidence and reporting was low and outcomes were predominantly measured in the short-term. However, the findings show potential for exercise therapy, pharmaceuticals, ERAS protocols, psychological/educational programmes, chewing gum and nutrition to benefit a broad range of physiological and psychological health outcomes. Conclusions Supportive interventions to date have taken many different forms with a range of potentially meaningful physiological and psychological health outcomes for cystectomy patients. Questions remain as to what magnitude of short-term health improvements would lead to clinically relevant changes in the overall patient experience of surgery and long-term recovery
