Triple combination of insulin glargine, sitagliptin and metformin in type 2 diabetes : the EASIE post-hoc analysis and extension trial

Q3Q1Aim We examined the effects of adding glargine to metformin–sitagliptin (MS + G) or sitagliptin to metformin–glargine (MG + S) therapy in type 2 diabetic persons uncontrolled after 24-week MS or MG dual therapy. Methods Subjects with A1c ≥ 7% on MS or MG treatment were respectively given glargine (0.2 U/kg starting dose) or sitagliptin (100 mg daily) for 12 weeks. The primary endpoint was number of subjects attaining A1c goal defined as < 7%. Results After receiving 24-week MS or MG dual therapy in the original EASIE Study, 42% (104/248) on MS and 68% (152/224) on MG attained A1c < 7% (p < 0.0001). The reduction in A1c was negatively associated with baseline fasting blood glucose (FBG) only in the MG group. Reduction in A1c was not related to baseline postprandial blood glucose (PPBG) in either the MG or MS group. Amongst 194 eligible patients, 57.7% (n = 111) entered the 12-week extension trial [MS + G:74/131, 57.3%; MG + S:37/63, 58.7%) with 55 (51.9%) subjects attaining goal [MS + G:59.2%; MG + S:37.1%] at week 12. The final insulin dosage was similar in both groups [MS + G: 0.46 U/kg; MG + S: 0.45 U/kg] with a higher rate of hypoglycemia in the MG + S (6.5 events/patient-year) than the MS + G group (3.2 events/patient-year), although neither group had severe hypoglycemia. Conclusion In metformin-treated type 2 diabetes patients, high fasting BG predicted greater A1c reductions with the addition of glargine, but not with sitagliptin. In subjects uncontrolled with 6-month dual therapy of MS or MG, 50% attained A1c < 7% with triple therapy of MS + G or MG + S in 12 weeks. The increased rate of hypoglycemia with MG + S (but not with MS + G) underlines the need to take measures to avoid the hypoglycemia

Nicolaides-Baraitser syndrome (NBS) is an infrequently described condition, thus far reported in five cases. In order to delineate the phenotype and its natural history in more detail, we gathered data on 18 hitherto unreported patients through a multi-center collaborative study, and follow-up data of the earlier reported patients. A detailed comparison of the 23 patients is provided. NBS is a distinct and recognizable entity, and probably has been underdiagnosed until now. Main clinical features are severe mental retardation with absent or limited speech, seizures, short stature, sparse hair, typical facial characteristics, brachydactyly, prominent finger joints and broad distal phalanges. Some of the features are progressive with time. The main differential diagnosis is Coffin-Siris syndrome. There is no important gender difference in occurrence and frequency of the syndrome, and all cases have been sporadic thus far. Microarray analysis performed in 14 of the patients gave normal results. Except for the progressive nature there are no clues to the cause. (C) 2009 Wiley-Liss, Inc

Insulin-like growth factor - Oestradiol crosstalk and mammary gland tumourigenesis

Development and differentiation of the mammary gland are dependent on the appropriate temporal expression of both systemically acting hormones and locally produced growth factors. A large body of evidence suggests that molecular crosstalk between these hormonal and growth factor axes is crucial for appropriate cell and tissue function. Two of the most important trophic factors involved in this process are the oestrogen (E) and insulin-like growth factor (IGF) molecular axes. The reciprocal crosstalk that exists between these pathways occurs at transcriptional/post-transcriptional and translational/post-translational levels regulate the expression and activity of genes involved in this process. In a clinical context an important consequence of such crosstalk in the mammary gland is the role which it may play in the aetiology, maintenance and development of breast tumours. Although oestradiol (E2) acting through oestrogen receptors α and β (ERα/β) is important for normal mammary gland function it can also provide a mitogenic drive to ER+ breast tumours. Therefore over several years anti-oestrogen therapeutic regimens in the form of selective oestrogen receptor modulators (SERMs - e.g. tamoxifen), aromatase inhibitors (AI e.g. anastrozole) or selective oestrogen receptor down regulators (SERDs - e.g. fulvestrant) have been used in an adjuvant setting to control tumour growth. Although initial response is usually encouraging, large cohorts of patients eventually develop resistance to these treatments leading to tumour recurrence and poor prognosis. There are potentially many routes by which breast cancer (BC) cells could escape anti-oestrogen based therapeutic strategies and one of the most studied is the possible growth factor mediated activation of ER(s). Because of this, growth factor modulation of ER activity has been an intensively studied route of molecular crosstalk in the mammary gland. The insulin-like growth factors (IGF-1 and -2) are amongst the most potent mitogens for mammary epithelial cells and there is accumulating evidence that they interact with the E2 axis to regulate mitogenesis, apoptosis, adhesion, migration and differentiation of mammary epithelial cells. Such interactions are bi-directional and E2 has been shown to regulate the expression and activity of IGF axis genes with the general effect of sensitising breast epithelial cells to the actions of IGFs and insulin. In this short review we discuss the evidence for the involvement of crosstalk between the insulin-like growth factor (IGF) and oestrogen axes in the mammary gland and comment on the relevance of such studies in the aetiology and treatment of BC

Complete Genome Sequence of Crohn's Disease-Associated Adherent-Invasive E. coli Strain LF82

International audienceBACKGROUND: Ileal lesions of Crohn's disease (CD) patients are abnormally colonized by pathogenic adherent-invasive Escherichia coli (AIEC) able to invade and to replicate within intestinal epithelial cells and macrophages. PRINCIPAL FINDINGS: We report here the complete genome sequence of E. coli LF82, the reference strain of adherent-invasive E. coli associated with ileal Crohn's disease. The LF82 genome of 4,881,487 bp total size contains a circular chromosome with a size of 4,773,108 bp and a plasmid of 108,379 bp. The analysis of predicted coding sequences (CDSs) within the LF82 flexible genome indicated that this genome is close to the avian pathogenic strain APEC_01, meningitis-associated strain S88 and urinary-isolated strain UTI89 with regards to flexible genome and single nucleotide polymorphisms in various virulence factors. Interestingly, we observed that strains LF82 and UTI89 adhered at a similar level to Intestine-407 cells and that like LF82, APEC_01 and UTI89 were highly invasive. However, A1EC strain LF82 had an intermediate killer phenotype compared to APEC-01 and UTI89 and the LF82 genome does not harbour most of specific virulence genes from ExPEC. LF82 genome has evolved from those of ExPEC B2 strains by the acquisition of Salmonella and Yersinia isolated or clustered genes or CDSs located on pLF82 plasmid and at various loci on the chromosome. CONCLUSION: LF82 genome analysis indicated that a number of genes, gene clusters and pathoadaptative mutations which have been acquired may play a role in virulence of AIEC strain LF82

The impact of charity and tax law/regulation on not-for-profit news organisations

The advent of digital media means that many news organisations are re-thinking their business models, and facing new challenges. But one sector which has seen growth, is the not-for-profit start up industry. In a new report, published jointly by the Reuters Institute and the Information Society Project at Yale University, Robert H Picard, the RISJ’s North America Representative and colleagues examine the legal framework in which these operate in. Picard, along with Valerie Belair-Gagnon and Sofia Ranchordás (both Yale University), studies the challenges thrown up by legal systems which don’t include journalistic activities within the concept of ‘charitable status’. “Legal and regulatory definitions of charitable purposes hinder news organisations from achieving charitable and tax exempt status and receiving the associated benefits in Australia, Canada, Ireland, the United Kingdom, and the United States,” says Picard. Drawing on the regulatory systems of Australia, Canada, Ireland, The UK and The US, the report sets out to gain a clearer understanding of the legal frameworks for charitable and tax exempt status for news organisations and the distinct challenges that may hinder their development.&nbsp
