Experience With Radical Resection in The Management of Proximal Bile Duct Cancer

Multiple surgical and nonsurgical approaches have been advocated for the treatment of proximal bile duct cancer. However, survival appears longest when a resection can be performed. Fifteen patients treated at a university center were managed with an aggressive surgical approach. Resection of the tumor was performed in 13 of 15 patients (87%). Of the patients undergoing resection, major hepatic resection was performed in 8 (62%), while excision of vessels with reconstruction was performed in 5 (38%). Eleven of the 13 resected patients (85%) were discharged from the hospital. Clinical symptoms of recurrent disease occurred between 3 and 36 months after surgery in 7 patients, 6 of whom have died. Three other patients are alive at 5, 21, and 36 months without clinical evidence of recurrence. There was no correlation between the completeness of resection and the duration of disease-free survival

Addition of adult-to-adult living donation to liver transplant programs improves survival but at an increased cost

Using outcomes data from the Adult-to-Adult Living Donor Liver Transplantation Cohort Study, we performed a cost-effectiveness analysis exploring the costs and benefits of living donor liver transplantation (LDLT). A multistage Markov decision analysis model was developed with treatment, including medical management only (strategy 1), waiting list with possible deceased donor liver transplantation (DDLT; strategy 2), and waiting list with possible LDLT or DDLT (strategy 3) over 10 years. Decompensated cirrhosis with medical management offered survival of 2.0 quality-adjusted life years (QALYs) while costing an average of $65,068, waiting list with possible DDLT offered 4.4-QALY survival and a mean cost of$151,613, and waiting list with possible DDLT or LDLT offered 4.9-QALY survival and a mean cost of $208,149. Strategy 2 had an incremental cost-effectiveness ratio (ICER) of$35,976 over strategy 1, whereas strategy 3 produced an ICER of $106,788 over strategy 2. On average, strategy 3 cost$47,693 more per QALY than strategy 1. Both DDLT and LDLT were cost-effective compared to medical management of cirrhosis over our 10-year study period. The addition of LDLT to a standard waiting list DDLT program is effective at improving recipient survival and preventing waiting list deaths but at a greater cost.

Reducing work pressure and IT problems and facilitating IT integration and audit & feedback help adherence to perioperative safety guidelines: a survey among 95 perioperative professionals

Background: To improve perioperative patient safety, guidelines for the preoperative, peroperative, andpostoperative phase were introduced in the Netherlands between 2010 and 2013. To help the implementation ofthese guidelines, we aimed to get a better understanding of the barriers and drivers of perioperative guidelineadherence and to explore what can be learned for future implementation projects in complex organizations.Methods: We developed a questionnaire survey based on the theoretical framework of Van Sluisveld et al. forclassifying barriers and facilitators. The questionnaire contained 57 statements derived from (a) an instrument formeasuring determinants of innovations by the Dutch Organization for Applied Scientific Research, (b) interviewswith quality and safety policy officers and perioperative professionals, and (c) a publication of Cabana et al. Thetarget group consisted of 232 perioperative professionals in nine hospitals. In addition to rating the statements on afive-point Likert scale (which were classified into the seven categories of the framework: factors relating to theintervention, society, implementation, organization, professional, patients, and social factors), respondents wereinvited to rank their three most important barriers in a separate, extra open-ended question.Results: Ninety-five professionals (41%) completed the questionnaire. Fifteen statements (26%) were considered tobe barriers, relating to social factors (N = 5), the organization (N = 4), the professional (N = 4), the patient (N = 1),and the intervention (N = 1). An integrated information system was considered an important facilitator (70.4%) aswell as audit and feedback (41.8%). The Barriers Top-3 question resulted in 75 different barriers in nearly allcategories. The most frequently reported barriers were as follows: time pressure (16% of the total number ofbarriers), emergency patients (8%), inefficient IT structure (4%), and workload (3%).Conclusions: We identified a wide range of barriers that are believed to hinder the use of the perioperative safetyguidelines, while an integrated information system and local data collection and feedback will also be necessary toengage perioperative teams. These barriers need to be locally prioritized and addressed by tailored implementationstrategies. These results may also be of relevance for guideline implementation in general in complex organizations.Trial registration: Dutch Trial Registry: NTR3568.Keywords: Guideline adherence, Implementation, Implementation barriers, Implementation facilitators, Patientsafety, Perioperative car

Increased adherence to perioperative safety guidelines associated with improved patient safety outcomes:a stepped-wedge, cluster-randomised multicentre trial

Background: National Dutch guidelines have been introduced to improve suboptimal perioperative care. A multifaceted implementation programme (IMPlementatie Richtlijnen Operatieve VEiligheid [IMPROVE]) has been developed to support hospitals in applying these guidelines. This study evaluated the effectiveness of IMPROVE on guideline adherence and the association between guideline adherence and patient safety. Methods: Nine hospitals participated in this unblinded, superiority, stepped-wedge, cluster RCT in patients with major noncardiac surgery (mortality risk >= 1%). IMPROVE consisted of educational activities, audit and feedback, reminders, organisational, team-directed, and patient-mediated activities. The primary outcome of the study was guideline adherence measured by nine patient safety indicators on the process (stop moments from the composite STOP bundle, and timely administration of antibiotics) and on the structure of perioperative care. Secondary safety outcomes included in-hospital complications, postoperative wound infections, mortality, length of hospital stay, and unplanned care. Results: Data were analysed for 1934 patients. The IMPROVE programme improved one stop moment: 'discharge from recovery room' (+16%; 95% confidence interval [CI], 9-23%). This stop moment was related to decreased mortality (-3%; 95% CI, -4% to -1%), fewer complications (-8%; 95% CI, -13% to -3%), and fewer unscheduled transfers to the ICU (-6%; 95% CI, -9% to -3%). IMPROVE negatively affected one other stop moment - 'discharge from the hospital' - possibly because of the limited resources of hospitals to improve all stop moments together. Conclusions: Mixed implementation effects of IMPROVE were found. We found some positive associations between guideline adherence and patient safety (i.e. mortality, complications, and unscheduled transfers to the ICU) except for the timely administration of antibiotics

Disruption of Protein Kinase A in Mice Enhances Healthy Aging

Mutations that cause a reduction in protein kinase A (PKA) activity have been shown to extend lifespan in yeast. Loss of function of mammalian RIIβ, a regulatory subunit of PKA expressed in brain and adipose tissue, results in mice that are lean and insulin sensitive. It was therefore hypothesized that RIIB null (RIIβ−/−) mice would express anti-aging phenotypes. We conducted lifespan studies using 40 mutant and 40 wild type (WT) littermates of equal gender numbers and found that both the median and maximum lifespans were significantly increased in mutant males compared to WT littermates. The median lifespan was increased from 884 days to 1005 days (p = 0.006 as determined by the log rank test) and the 80% lifespan (defined here as 80% deaths) was increased from 941 days to 1073 days (p = 0.004 as determined by the Wang-Allison test). There was no difference in either median or 80% lifespan in female genotypes. WT mice of both genders became increasingly obese with age, while mutant mice maintained their lean phenotype into old age. Adiposity was found to correlate with lifespan for males only. 50% of male mice between 30 and 35 g, corresponding to about 5% body fat, for either genotype lived over 1000 days. No male mouse outside of this weight range achieved this lifespan. During their last month of life, WT mice began losing weight (a total of 8% and 15% of body weight was lost for males and females, respectively), but RIIβ−/− male mice maintained their lean body mass to end of life. This attenuation of decline was not seen in female mutant mice. Old male mutant mice were insulin sensitive throughout their life. Both genders showed modestly lower blood glucose levels in old mutants compared to WT. Male mutants were also resistant to age-induced fatty liver. Pathological assessment of tissues from end of life male mutant mice showed a decrease in tumor incidence, decreased severity of renal lesions, and a trend towards a decrease in age-related cardiac pathology. These findings help establish the highly conserved nature of PKA and suggest that disruption of PKA affects physiological mechanisms known to be associated with healthy aging

The pedagogy and principles of teaching therapeutic practice with children and young people.

Technical approaches suggesting that systematically produced, generalized, and scientific knowledge are the most solid foundations for practice present significant challenges for the social work profession, in which the decisions faced often are not technical but rather moral, requiring the application of ethically based and intuitive skills. Meanwhile, the command, control, and measurement of outcomes in social work practice also present significant conundrums for the delivery of relational person-centered social work and social care. With a focus too often on efficiency rather than on effectiveness, this managerialistic approach frequently fails to acknowledge the complexity inherent in the act of caring. In this context and framework, teaching therapeutic practice with children draws a balance between traditional systematic teaching methods and use of creative media including art, play, and music. This article outlines the positive contribution to professional social work practice that the teaching of therapeutic approaches to child care can make
