Future air pollution in the Shared Socio-economic Pathways
Emissions of air pollutants such as sulfur and nitrogen oxides and particulates have significant health impacts as well as effects on natural and anthropogenic ecosystems. These same emissions also can change atmospheric chemistry and the planetary energy balance, thereby impacting global and regional climate. Long-term scenarios for air pollutant emissions are needed as inputs to global climate and chemistry models, and for analysis linking air pollutant impacts across sectors. In this paper we present methodology and results for air pollutant emissions in Shared Socioeconomic Pathways (SSP) scenarios. We first present a set of three air pollution narratives that describe high, central, and low pollution control ambitions over the 21st century. These narratives are then translated into quantitative guidance for use in integrated assessment models. The resulting pollutant emission trajectories under the SSP scenarios cover a wider range than the scenarios used in previous international climate model comparisons. In the SSP3 and SSP4 scenarios, where economic, institutional and technological limitations slow air quality improvements, global pollutant emissions over the 21st century can be comparable to current levels. Pollutant emissions in the SSP1 scenarios fall to low levels due to the assumption of technological advances and successful global action to control emissions
Size Doesn't Matter: Towards a More Inclusive Philosophy of Biology
notes: As the primary author, OâMalley drafted the paper, and gathered and analysed data (scientific papers and talks). Conceptual analysis was conducted by both authors.publication-status: Publishedtypes: ArticlePhilosophers of biology, along with everyone else, generally perceive life to fall into two broad categories, the microbes and macrobes, and then pay most of their attention to the latter. âMacrobeâ is the word we propose for larger life forms, and we use it as part of an argument for microbial equality. We suggest that taking more notice of microbes â the dominant life form on the planet, both now and throughout evolutionary history â will transform some of the philosophy of biologyâs standard ideas on ontology, evolution, taxonomy and biodiversity. We set out a number of recent developments in microbiology â including biofilm formation, chemotaxis, quorum sensing and gene transfer â that highlight microbial capacities for cooperation and communication and break down conventional thinking that microbes are solely or primarily single-celled organisms. These insights also bring new perspectives to the levels of selection debate, as well as to discussions of the evolution and nature of multicellularity, and to neo-Darwinian understandings of evolutionary mechanisms. We show how these revisions lead to further complications for microbial classification and the philosophies of systematics and biodiversity. Incorporating microbial insights into the philosophy of biology will challenge many of its assumptions, but also give greater scope and depth to its investigations
Supplementary Material for: Meta-Analysis of the Risk of Subsequent Mood Episodes in Bipolar Disorder
<p><b><i>Background:</i></b> Reported relapse and recurrence rates in
bipolar disorder (BD) differ significantly between studies. Most data
originate from highly selective patients participating in sponsored
randomized controlled trials with narrow inclusion criteria. To estimate
the true risk of a subsequent mood episode (SME) under real-world
conditions, we conducted a meta-analysis of rates of SME as reported in
naturalistic BD studies. <b><i>Methods:</i></b> PubMed, ScienceDirect,
Scopus, and Web of Knowledge were searched until July 2015. Studies
reporting the time until the emergence of an SME, from which individual
data or Kaplan-Meier plots with censors marked could be retrieved, were
included. <b><i>Results:</i></b> Twelve studies comprising 5,837
patients met the inclusion criteria. The median time to an SME in adults
after an index episode was 1.44 years. The risk of an SME was 44%
during the first year. Not having a SME during this first year lowered
this risk to 19% in the second year. The risk was higher in bipolar II
disorder (BD-II) than in bipolar I disorder (BD-I; HR = 1.5). In BD-I,
the risk of a subsequent manic, mixed, or depressive mood episode was
higher after an index episode of the same polarity (HR = 1.89-5.14). The
overall risk of an SME was higher in patients with persisting
subsyndromal symptoms (HR = 2.17). <b><i>Conclusions:</i></b> The data
from this study provide a more reliable estimate of the risk of an SME
in BD in real-world settings. Further research into the longitudinal
course of BD-II is warranted to confirm its role as a risk factor for
SME.</p
The Status of EMDR Therapy in the Treatment of Posttraumatic Stress Disorder 30 Years After Its Introduction
Given that 2019 marks the 30th anniversary of eye movement desensitization and reprocessing (EMDR) therapy, the purpose of this article is to summarize the current empirical evidence in support of EMDR therapy as an effective treatment intervention for posttraumatic stress disorder (PTSD). Currently, there are more than 30 randomized controlled trials (RCT) demonstrating the effectiveness in patients with this debilitating mental health condition, thus providing a robust evidence base for EMDR therapy as a first-choice treatment for PTSD. Results from several meta-analyses further suggest that EMDR therapy is equally effective as its most important trauma-focused comparator, that is, trauma-focused cognitive behavioral therapy, albeit there are indications from some studies that EMDR therapy might be more efficient and cost-effective. There is emerging evidence showing that EMDR treatment of patients with psychiatric disorders, such as psychosis, in which PTSD is comorbid, is also safe, effective, and efficacious. In addition to future well-crafted RCTs in areas such as combat-related PTSD and psychiatric disorders with comorbid PTSD, RCTs with PTSD as the primary diagnosis remain pivotal in further demonstrating EMDR therapy as a robust treatment intervention
The Current Status of EMDR Therapy Involving the Treatment of Complex Posttraumatic Stress Disorder
Complex posttraumatic stress disorder (CPTSD) is a diagnostic entity that will be included in the forthcoming edition of the International Classification of Diseases, 11th Revision (ICD-11). It denotes a severe form of PTSD, comprising not only the symptom clusters of PTSD (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition [DSM-IV-TR]), but also clusters reflecting difficulties in regulating emotions, disturbances in relational capacities, and adversely affected belief systems about oneself, others, or the world. Evidence is mounting suggesting that first-line trauma-focused treatments, including eye movement desensitization and reprocessing (EMDR) therapy, are effective not only for the treatment of PTSD, but also for the treatment of patients with a history of early childhood interpersonal trauma who are suffering from symptoms characteristic of CPTSD. However, controversy exists as to when EMDR therapy should be offered to people with CPTSD. This article reviews the evidence in support of EMDR therapy as a first-line treatment for CPTSD and addresses the fact that there appears to be little empirical evidence supporting the view that there should be a stabilization phase prior to trauma processing in working with CPTSD
Neuropsychological and neuroimaging underpinnings of schizoaffective disorder : a systematic review
Objectives
The neurobiological basis and nosological status of schizoaffective disorder remains elusive and controversial. This study provides a systematic review of neurocognitive and neuroimaging findings in the disorder.
Methods
A comprehensive literature search was conducted via PubMed, ScienceDirect, Scopus and Web of Knowledge (from 1949 to 31st March 2015) using the keyword \u2018schizoaffective disorder\u2019 and any of the following terms: \u2018neuropsychology\u2019, \u2018cognition\u2019, \u2018structural neuroimaging\u2019, \u2018functional neuroimaging\u2019, \u2018multimodal\u2019, \u2018DTI\u2019 and \u2018VBM\u2019. Only studies that explicitly examined a well defined sample, or subsample, of patients with schizoaffective disorder were included.
Results
Twenty-two of 43 neuropsychological and 19 of 51 neuroimaging articles fulfilled inclusion criteria. We found a general trend towards schizophrenia and schizoaffective disorder being related to worse cognitive performance than bipolar disorder. Grey matter volume loss in schizoaffective disorder is also more comparable to schizophrenia than to bipolar disorder which seems consistent across further neuroimaging techniques.
Conclusions
Neurocognitive and neuroimaging abnormalities in schizoaffective disorder resemble more schizophrenia than bipolar disorder. This is suggestive for schizoaffective disorder being a subtype of schizophrenia or being part of the continuum spectrum model of psychosis, with schizoaffective disorder being more skewed towards schizophrenia than bipolar disorder
The current status of EMDR therapy, specific target areas, and goals for the future
While eye movement desensitization and reprocessing (EMDR) is considered an evidence-based treatment for posttraumatic stress disorder (PTSD) in adults, there are differences as to how various international treatment guidelines judge the strength of this evidence base. Furthermore, in areas other than adult PTSD, major guidelines differ even more as to the strength of the evidence base and when to use EMDR. In 2019, the âCouncil of Scholars: the Future of EMDR Therapy Projectâ was initiated. Several working groups were established, with one assigned to the focus area âresearch.â This article is a product of that working group. Firstly the group concluded that there were five areas where there was some base that EMDR was effective but more data was needed to increase the likelihood that it would be considered in future international treatment guidelines. These areas were PTSD in children and adolescents, early EMDR interventions, combat PTSD, unipolar depression, and chronic pain. In addition, research into costeffectiveness of EMDR therapy was identified as one of the priorities. A hierarchical system was used for classifying and rating evidence in the focus areas. After assessing the 120 outcome studies pertaining to the focus areas we conclude that for two of the areas (i.e., PTSD in children and adolescents and EMDR early interventions research) the strength of the evidence is rated at the highest level, whereas the other areas obtain the second highest level. Some general recommendations for improving the quality of future research on the effectiveness of EMDR therapy are formulated
