The Communist Party and the New Party
This is an Author's Accepted Manuscript of an article published in Contemporary British History, vol. 23(4), 2009, pp.477-491 copyright Taylor & Francis, available online at: http://www.tandfonline.com/doi/full/10.1080/13619460903198101The New Party was never at the centre of the concerns of the Communist Party of Great Britain (CPGB). However, the CPGB had to take a line on the new organisation when it was formed, and tried to use it to smear Labour and Independent Labour Party politicians as enemies of the working class. As the 1931 political crisis unfolded, the New Party became increasingly an irrelevance at the side of the much more tangible threat of the National government, although communists did campaign against Mosley in late 1931. Ultimately, the New Party was significant for the communists because it seemed to offer some vindication of the 'class against class' line; because it suggested that the CPGB was not always wrong in its analysis; because it led to increased attention to the party's youth movement; and because it led to the leading left-wing polemicist of the 1930s, John Strachey, working with the CPGB for almost a decade
Longitudinal change in the BODE index predicts mortality in severe emphysema
Rationale: The predictive value of longitudinal change in BODE (Body
mass index, airflow Obstruction, Dyspnea, and Exercise capacity)
index has received limited attention. We hypothesized that decrease
in a modified BODE (mBODE) would predict survival in National
Emphysema Treatment Trial (NETT) patients.
Objectives: To determine how the mBODE score changes in patients
with lung volume reduction surgery versus medical therapy and correlations
with survival.
Methods: Clinical data were recorded using standardized instruments.
The mBODE was calculated and patient-specific mBODE trajectories
during 6, 12, and 24 months of follow-up were estimated using
separate regressions for each patient. Patients were classified as
having decreasing, stable, increasing, or missing mBODE based on
their absolute change from baseline. The predictive ability of mBODE
change on survival was assessed using multivariate Cox regression
models. The index of concordance was used to directly compare the
predictive ability of mBODE and its separate components.
Measurements and Main Results: The entire cohort (610 treated medically
and 608 treated surgically) was characterized by severe airflow
obstruction, moderate breathlessness, and increased mBODE at baseline.
A wide distribution of change in mBODE was seen at follow-up. An
increase in mBODE of more than 1 point was associated with increased
mortality in surgically and medically treated patients. Surgically
treated patients were less likely to experience death or an increase
greater than 1 in mBODE. Indices of concordance showed that mBODE
change predicted survival better than its separate components.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/91943/1/2008 AJRCCM Longitudinal change in the BODE index predicts mortality in severe emphysema.pd
Sex Differences in Severe Pulmonary Emphysema
Rationale: Limited data on sex differences in advanced COPD are
available.
Objectives: To compare male and female emphysema patients with
severe disease.
Methods: One thousand fifty-three patients (38.8% female) evaluated
for lung volume reduction surgery as part of the National
Emphysema Treatment Trial were analyzed.
Measurements and Main Results: Detailed clinical, physiological, and
radiological assessment, including quantitation of emphysema severity
and distribution from helical chest computed tomography,
was completed. In a subgroup (n = 101), airway size and thickness
was determined by histological analyses of resected tissue. Women
were younger and exhibited a lower bodymass index (BMI), shorter
smoking history, less severe airflow obstruction, lower DLCO and
arterial PO2, higher arterial PCO2, shorter six-minute walk distance,
and lower maximal wattage during oxygen-supplemented cycle
ergometry. For a given FEV1% predicted, age, number of packyears,
and proportion of emphysema, women experienced greater
dyspnea, higher modified BODE, more depression, lower SF-36
mental component score, and lower quality of well-being. Overall
emphysema was less severe in women, with the difference from men
most evident in the outer peel of the lung. Females had thicker small
airway walls relative to luminal perimeters.
Conclusions: In patients with severe COPD, women, relative to men,
exhibit anatomically smaller airway lumens with disproportionately
thicker airway walls, and emphysema that is less extensive and
characterized by smaller hole size and less peripheral involvement.The National Emphysema Treatment Trial (NETT) was supported by contracts

Integration of antiretroviral therapy with tuberculosis treatment.
Background. We previously reported that integrating antiretroviral therapy (ART) with tuberculosis treatment reduces mortality. However, the timing for the initiation of ART during tuberculosis treatment remains unresolved.
Methods. We conducted a three-group, open-label, randomized, controlled trial in South Africa involving 642 ambulatory patients, all with tuberculosis (confirmed by a positive sputum smear for acid-fast bacilli), human immunodeficiency virus infection, and a CD4+ T-cell count of less than 500 per cubic millimeter. Findings in the earlier-
ART group (ART initiated within 4 weeks after the start of tuberculosis treatment, 214 patients) and later-ART group (ART initiated during the first 4 weeks of the continuation phase of tuberculosis treatment, 215 patients) are presented here.
Results. At baseline, the median CD4+ T-cell count was 150 per cubic millimeter, and the median viral load was 161,000 copies per milliliter, with no significant differences between the two groups. The incidence rate of the acquired immunodeficiency syndrome (AIDS) or death was 6.9 cases per 100 person-years in the earlier-ART group
(18 cases) as compared with 7.8 per 100 person-years in the later-ART group (19 cases) (incidence-rate ratio, 0.89; 95% confidence interval [CI], 0.44 to 1.79; P = 0.73). However, among patients with CD4+ T-cell counts of less than 50 per cubic millimeter, the incidence rates of AIDS or death were 8.5 and 26.3 cases per 100 person-years, respectively (incidence-rate ratio, 0.32; 95% CI, 0.07 to 1.13; P = 0.06). The incidence rates of the immune reconstitution inflammatory syndrome (IRIS) were 20.1 and 7.7 cases per 100 person-years, respectively (incidence-rate ratio, 2.62; 95% CI, 1.48 to 4.82; P<0.001). Adverse events requiring a switching of antiretroviral drugs occurred in 10 patients in the earlier-ART group and 1 patient in the later-ART group (P = 0.006).
Conclusions. Early initiation of ART in patients with CD4+ T-cell counts of less than 50 per cubic millimeter increased AIDS-free survival. Deferral of the initiation of ART to the first 4 weeks of the continuation phase of tuberculosis therapy in those with higher CD4+ T-cell counts reduced the risks of IRIS and other adverse events related to ART without increasing the risk of AIDS or death
Can Historical Institutionalism be Applied to Political Regime Development in Africa?
Historical institutionalism has been used to explain the emergence of democracy and dictatorship in various regions of the world, but not applied to political development in Africa. Based on the recently refined concepts of historical institutionalism, the aim of this study is to provide a framework for the analysis of the various regime types that have been established in Africa during the last two decades: democratic, hybrid and authoritarian. Surprisingly little effort has been dedicated to a historically grounded explanation of these regime types. Against a common claim that African politics is mainly driven by informal institutions or behaviours, we argue that an institution-based examination of African politics is justified. We then provide a proposition of how to link up concepts of historical institutionalism with empirical cases in Africa, within a comparative approach. Our proposition for tracing specific development paths will not be based on the regimes as a 'whole', but on the deconstruction of a political regime into partial regimes and subsequently into selected formal and informal institutions. This will allow for an empirical analysis of the different components of a regime over long periods of time, and thus for path-dependent analyses of regime development
UK guideline on transition of adolescent and young persons with chronic digestive diseases from paediatric to adult care
The risks of poor transition include delayed and inappropriate transfer that can result in disengagement with healthcare. Structured transition care can improve control of chronic digestive diseases and long-term health-related outcomes. These are the first nationally developed guidelines on the transition of adolescent and young persons (AYP) with chronic digestive diseases from paediatric to adult care. They were commissioned by the Clinical Services and Standards Committee of the British Society of Gastroenterology under the auspices of the Adolescent and Young Persons (A&YP) Section. Electronic searches for English-language articles were performed with keywords relating to digestive system diseases and transition to adult care in the Medline (via Ovid), PsycInfo (via Ovid), Web of Science and CINAHL databases for studies published from 1980 to September 2014. The quality of evidence and grading of recommendations was appraised using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The limited number of studies in gastroenterology and hepatology required the addition of relevant studies from other chronic diseases to be included. These guidelines deal specifically with the transition of AYP living with a diagnosis of chronic digestive disease and/or liver disease from paediatric to adult healthcare under the following headings; 1. Patient populations involved in AYP transition 2. Risks of failing transition or poor transition 3. Models of AYP transition 4. Patient and carer/parent perspective in AYP transition 5.

Identification and developmental expression of the full complement of Cytochrome P450 genes in Zebrafish

The definitive version was published in BMC Genomics 11 (2010): 643, doi:10.1186/1471-2164-11-643.Increasing use of zebrafish in drug discovery and mechanistic toxicology demands knowledge of cytochrome P450 (CYP) gene regulation and function. CYP enzymes catalyze oxidative transformation leading to activation or inactivation of many endogenous and exogenous chemicals, with consequences for normal physiology and disease processes. Many CYPs potentially have roles in developmental specification, and many chemicals that cause developmental abnormalities are substrates for CYPs. Here we identify and annotate the full suite of CYP genes in zebrafish, compare these to the human CYP gene complement, and determine the expression of CYP genes during normal development. Zebrafish have a total of 94 CYP genes, distributed among 18 gene families found also in mammals. There are 32 genes in CYP families 5 to 51, most of which are direct orthologs of human CYPs that are involved in endogenous functions including synthesis or inactivation of regulatory molecules. The high degree of sequence similarity suggests conservation of enzyme activities for these CYPs, confirmed in reports for some steroidogenic enzymes (e.g. CYP19, aromatase; CYP11A, P450scc; CYP17, steroid 17a-hydroxylase), and the CYP26 retinoic acid hydroxylases. Complexity is much greater in gene families 1, 2, and 3, which include CYPs prominent in metabolism of drugs and pollutants, as well as of endogenous substrates. There are orthologous relationships for some CYP1 s and some CYP3 s between zebrafish and human. In contrast, zebrafish have 47 CYP2 genes, compared to 16 in human, with only two (CYP2R1 and CYP2U1) recognized as orthologous based on sequence. Analysis of shared synteny identified CYP2 gene clusters evolutionarily related to mammalian CYP2 s, as well as unique clusters. Transcript profiling by microarray and quantitative PCR revealed that the majority of zebrafish CYP genes are expressed in embryos, with waves of expression of different sets of genes over the course of development. Transcripts of some CYP occur also in oocytes. The results provide a foundation for the use of zebrafish as a model in toxicological, pharmacological and chemical disease research.This work was supported by NIH grants R01ES015912 and P42ES007381 (Superfund Basic Research Program at Boston University) (to JJS).

Multiple Recurrent De Novo CNVs, Including Duplications of the 7q11.23 Williams Syndrome Region, Are Strongly Associated with Autism
SummaryWe have undertaken a genome-wide analysis of rare copy-number variation (CNV) in 1124 autism spectrum disorder (ASD) families, each comprised of a single proband, unaffected parents, and, in most kindreds, an unaffected sibling. We find significant association of ASD with de novo duplications of 7q11.23, where the reciprocal deletion causes Williams-Beuren syndrome, characterized by a highly social personality. We identify rare recurrent de novo CNVs at five additional regions, including 16p13.2 (encompassing genes USP7 and C16orf72) and Cadherin 13, and implement a rigorous approach to evaluating the statistical significance of these observations. Overall, large de novo CNVs, particularly those encompassing multiple genes, confer substantial risks (OR = 5.6; CI = 2.6–12.0, p = 2.4 × 10-7). We estimate there are 130–234 ASD-related CNV regions in the human genome and present compelling evidence, based on cumulative data, for association of rare de novo events at 7q11.23, 15q11.2-13.1, 16p11.2, and Neurexin 1
Phase I study of the aurora A kinase inhibitor alisertib with induction chemotherapy in patients with acute myeloid leukemia
Aberrant expression of aurora kinase A is implicated in the genesis of various neoplasms, including acute myeloid leukemia. Alisertib, an aurora A kinase inhibitor, has demonstrated efficacy as monotherapy in trials of myeloid malignancy, and this efficacy appears enhanced in combination with conventional chemotherapies. In this phase I, dose-escalation study, newly diagnosed patients received conventional induction with cytarabine and idarubicin, after which alisertib was administered for 7 days. Dose escalation occurred via cohorts. Patients could then receive up to four cycles of consolidation, incorporating alisertib, and thereafter alisertib maintenance for up to 12 months. Twenty-two patients were enrolled. One dose limiting toxicity occurred at dose level 2 (prolonged thrombocytopenia), and the recommended phase 2 dose was established at 30mg twice daily. Common therapy-related toxicities included cytopenias and mucositis. Only three (14%) patients had persistent disease at mid-cycle, requiring “5+2” reinduction. The composite remission rate (complete remission and complete remission with incomplete neutrophil recovery) was 86% (nineteen of twenty-two patients; 90% CI 68–96%). Among those over age 65 and those with high-risk disease (secondary acute leukemia or cytogenetically high-risk disease), the composite remission rate was 88% and 100%, respectively. The median follow up was 13.5 months. Of those treated at the recommended phase 2 dose, the 12-month overall survival and progression-free survival were 62% (90% CI 33–81%) and 42% (90% CI 17–65%), respectively. Alisertib is well tolerated when combined with induction chemotherapy in acute myeloid leukemia, with a promising suggestion of efficacy. (clinicaltrials.gov Identifier:01779843)
