TL;DR: In this paper, the social mechanisms of linguistic change are discussed, and the distinction drawn by Bynon (1977) between two quite different approaches to linguistic change is made, and more recently the specification of 'possible' and 'impossible' processes of change has been seen as an important theoretical goal.
Abstract: This paper is concerned with the social mechanisms of linguistic change, and we begin by noting the distinction drawn by Bynon (1977) between two quite different approaches to the study of linguistic change. The first and more idealized, associated initially with traditional nineteenth century historical linguistics, involves the study of successive ‘states of the language’, states reconstructed by the application of comparative techniques to necessarily partial historical records. Generalizations (in the form of laws) about the relationships between these states may then be made, and more recently the specification of ‘possible’ and ‘impossible’ processes of change has been seen as an important theoretical goal.

TL;DR: A thorough understanding of the organismal responses occurring during bleaching will help explain changes in coral populations and in the coral reef community, and perhaps assist in predicting the future of reef corals and coral reefs during the next century of global climate change.
Abstract: 'It should be clear that the upper temperature limit for life cannot be accurately defined' (Schmidt-Nielsen 1996). The thermal physiology of zooxanthellate reef corals is reviewed in this paper in the context of organismal and biochemical responses occurring during coral bleaching, with emphasis on methods of detection and interpretation of animal and algal symbiont stress. Coral bleaching, as presently defined in the literature, is a highly subjective term used to describe a variety of conditions pertaining to low symbiont densities in the coral–algal complex, including response to thermal stress. Three general types of high-temperature bleaching are defined: physiological bleaching, which may or may not include higher-than-normal temperature responses; algal-stress bleaching, involving dysfunction of symbiotic algae at high light and/or high temperatures; and animal-stress bleaching, where coral cells containing symbiotic algae are shed from the gastrodermal layer of cells. Since none of these methods of bleaching is mutually exclusive, a combination of intrusive and non-intrusive techniques is necessary to determine which mechanisms of symbiont loss are occurring. While quantification of symbiont densities, algal pigments, and coral tissue biomass provide unambiguous evidence of bleaching severity, measurements of physiological and biochemical degradation offer additional correlative evidence of temperature stress. Pulse-amplitude-modulated (PAM) fluorometry has emerged as an easy and relatively inexpensive non-invasive technique for monitoring symbiotic algal function both in situ and in the laboratory, when proper assumptions and interpretations are made. The roles of global warming, water quality, acclimation/adaptation processes, and relation to coral disease and reef heterogeneity are also discussed. A thorough understanding of the organismal responses occurring during bleaching will help explain changes in coral populations and in the coral reef community, and perhaps assist in predicting the future of reef corals and coral reefs during the next century of global climate change.

TL;DR: An international DILI Expert Working Group of clinicians and scientists reviewed current DILi terminology and diagnostic criteria so as to develop more uniform criteria that would define and characterize the spectrum of clinical syndromes that constitute D ILI.
Abstract: Drug-induced liver injury (DILI) is the most frequent reason cited for the withdrawal of approved drugs from the market and accounts for up to 15% of the cases of acute liver failure. Investigators around the globe have begun to identify and study patients with DILI; several large registries and tissue banks are being established. In order to gain the maximum scientific benefit from these efforts, the definitions and terminology related to the clinical phenotypes of DILI must be harmonized. For this purpose, an international DILI Expert Working Group of clinicians and scientists reviewed current DILI terminology and diagnostic criteria so as to develop more uniform criteria that would define and characterize the spectrum of clinical syndromes that constitute DILI. Consensus was established with respect to the threshold criteria for definition of a case as being DILI, the pattern of liver injury, causality assessment, severity, and chronicity. Consensus was also reached on approaches to characterizing DILI in the setting of chronic liver diseases, including autoimmune hepatitis (AIH).

11 Dec 2011TL;DR: The current state of scientific knowledge on DLB is reviewed to show that treatment with cholinesterase inhibitors is well tolerated by most patients and substantially improves cognitive and neuropsychiatric symptoms.
Abstract: Dementia with Lewy bodies is relatively common cause of degenerative dementia in older people. This debilitating disorder is comprised of core features including dementia, fluctuating cognition, motor parkinsonism, and visual hallucinations, as well as other symptoms such as rapid eye movement sleep behavior disorder, olfactory dysfunction, autonomic dysfunction, sensitivity to neuroleptics, anxiety, depression, and delusions. Pharmacotherapy, so far exclusively symptomatic, should be implemented with caution and only when symptoms are disturbing and after non-pharmacological interventions fail. Treatment with acetylcholinesterase inhibitors (AChEi), such as donepezil and rivastimine, is considered a first line therapy. There is substantial evidence that AChEi address cognitive as well as behavioral symptoms without substantially increasing parkinsonism. Dopaminergic treatment for motor symptoms requires balancing risk of worsened psychosis and is consider only moderately beneficial.

TL;DR: The proposed system for defining and recording perioperative complications associated with esophagectomy provides an infrastructure to standardize international data collection and facilitate future comparative studies and quality improvement projects.
Abstract: Introduction: Perioperative complications influence long- and short-term outcomes after esophagectomy. The absence of a standardized system for defining and recording complications and quality measures after esophageal resection has meant that there is wide variation in evaluating their impact on these outcomes. Methods: The Esophageal Complications Consensus Group comprised 21 high-volume esophageal surgeons from 14 countries, supported by all the major thoracic and upper gastrointestinal professional societies. Delphi surveys and group meetings were used to achieve a consensus on standardized methods for defining complications and quality measures that could be collected in institutional databases and national audits. Results: A standardized list of complications was created to provide a template for recording individual complications associated with esophagectomy. Where possible, these were linked to preexisting international definitions. A Delphi survey facilitated production of specific definitions for anastomotic leak, conduit necrosis, chyle leak, and recurrent nerve palsy. An additional Delphi survey documented consensus regarding critical quality parameters recommended for routine inclusion in databases. These quality parameters were documentation on mortality, comorbidities, completeness of data collection, blood transfusion, grading of complication severity, changes in level of care, discharge location, and readmission rates. Conclusions: The proposed system for defining and recording perioperative complications associated with esophagectomy provides an infrastructure to standardize international data collection and facilitate future comparative studies and quality improvement projects.
