TL;DR: Telaprevir combined with peginterferon plus ribavirin significantly improved rates of sustained virologic response in patients with previously treated HCV infection, regardless of whether there was a lead-in phase.
Abstract: Methods In this randomized, phase 3 trial, we evaluated the addition of telaprevir to peginter feron alfa-2a plus ribavirin in patients with HCV genotype 1 infection who had no response or a partial response to previous therapy or who had a relapse after an initial response. A total of 663 patients were assigned to one of three groups: the T12PR48 group, which received telaprevir for 12 weeks and peginterferon plus ribavirin for a total of 48 weeks; the lead-in T12PR48 group, which received 4 weeks of peginterferon plus ribavirin followed by 12 weeks of telaprevir and peginterferon plus ribavirin for a total of 48 weeks; and the control group (PR48), which received peginterferon plus ribavirin for 48 weeks. The primary end point was the rate of sustained virologic response, which was defined as undetectable HCV RNA 24 weeks after the last planned dose of a study drug. Results Rates of sustained virologic response were significantly higher in the two telaprevir groups than in the control group among patients who had a previous relapse (83% in the T12PR48 group, 88% in the lead-in T12PR48 group, and 24% in the PR48 group), a partial response (59%, 54%, and 15%, respectively), and no response (29%, 33%, and 5%, respectively) (P<0.001 for all comparisons). Grade 3 adverse events (mainly anemia, neutropenia, and leukopenia) were more frequent in the telaprevir groups than in the control group (37% vs. 22%). Conclusions Telaprevir combined with peginterferon plus ribavirin significantly improved rates of sustained virologic response in patients with previously treated HCV infection, re gardless of whether there was a lead-in phase.

TL;DR: In this article, the authors ask specifically what kinds of motivation are needed to generate and transfer tacit knowledge, as opposed to explicit knowledge, for knowledge generation and transfer in an organizational form.
Abstract: Employees are motivated intrinsically as well as extrinsically. Intrinsic motivation is crucial when tacit knowledge in and between teams must be transferred. Organizational forms enable different kinds of motivation and have different capacities to generate and transfer tacit knowledge. Since knowledge generation and transfer are essential for a firm's sustainable competitive advantage, we ask specifically what kinds of motivation are needed to generate and transfer tacit knowledge, as opposed to explicit knowledge.

TL;DR: There was no convincing evidence that the outcome of anorexia nervosa improved over the second half of the last century, and vomiting, bulimia, and purgative abuse, chronicity of illness, and obsessive-compulsive personality symptoms are unfavorable prognostic features.
Abstract: follow-up. Results: There were large variations in the outcome parameters across studies. Mortality estimated on the basis of both crude and standardized rates was significantly high. Among the surviving patients, less than one-half recovered on average, whereas one-third improved, and 20% remained chronically ill. The normalization of the core symptoms, involving weight, menstruation, and eating behaviors, was slightly better when each symptom was analyzed in isolation. The presence of other psychiatric disorders at follow-up was very common. Longer duration of follow-up and, less strongly, younger age at onset of illness were associated with better outcome. There was no convincing evidence that the outcome of anorexia nervosa improved over the second half of the last century. Several prognostic features were isolated, but there is conflicting evidence. Most clearly, vomiting, bulimia, and purgative abuse, chronicity of illness, and obsessive-compulsive personality symptoms are unfavorable prognostic features. Conclusions: Anorexia nervosa did not lose its relatively poor prognosis in the 20th century. Advances in etiology and treatment may improve the course of patients with anorexia nervosa in the future.

TL;DR: The new edition of the World Health Organization (WHO) book on ‘Histological Typing of Tumours of the Central Nervous System’ reflects the progress in brain tumour classification which has been achieved since publication of the first edition in 1979.
Abstract: The new edition of the World Health Organization (WHO) book on 'Histological Typing of Tumours of the Central Nervous System' reflects the progress in brain tumour classification which has been achieved since publication of the first edition in 1979. Several new tumour entities have been added, including the pleomorphic xanthoastrocytoma, central neurocytoma, the infantile desmoplastic astrocytoma/ganglioglioma, and the dysembryoplastic neuroepithelial tumour. The list of histological variants has also been expanded. In line with recent morphological and molecular data on glioma progression, the glioblastoma is now grouped together with astrocytic tumours. The classification of childhood tumours has been largely retained, the diagnosis primitive neuroectodermal tumour (PNET) only being recommended as a generic term for cerebellar medulloblastomas and neoplasms that are histologically indistinguishable from medulloblastoma but located in the CNS at sites other than the cerebellum. The WHO grading scheme was revised and adapted to new entities but its use, as before, remains optional.

TL;DR: A multicenter historical cohort study of 2015 subjects with chronic pancreatitis who were recruited from clinical centers in six countries finds that pancreatitis may be a risk factor for pancreatic cancer, but the magnitude of the relation between these two diseases is unclear.
Abstract: Background The results of case-control studies and anecdotal reports suggest that pancreatitis may be a risk factor for pancreatic cancer, but there have been no studies of sufficient size and power to assess the magnitude of the relation between these two diseases. Methods and Results We undertook a multicenter historical cohort study of 2015 subjects with chronic pancreatitis who were recruited from clinical centers in six countries. A total of 56 cancers were identified among these patients during a mean (±SD) follow-up of 7.4 ±6.2 years. The expected number of cases of cancer calculated from country-specific incidence data and adjusted for age and sex was 2.13, yielding a standardized incidence ratio (the ratio of observed to expected cases) of 26.3 (95 percent confidence interval, 19.9 to 34.2). For subjects with a minimum of two or five years of follow-up, the respective standardized incidence ratios were 16.5 (95 percent confidence interval, 11.1 to 23.7) and 14.4 (95 percent confidence interval, 8...
