Aim As the understanding of anal dysplasia continues to develop, controversy remains regarding treatment of these lesions. The purpose of this study was to evaluate lesion type (flat versus exophytic) and the association between morphology and dysplasia. Methods This is a single-centre retrospective analysis of a prospectively collected pathological database of patients > 17 years old who underwent operative excision/biopsies for presumed anal condyloma or dysplasia from 2009-2018. Analysis includes comparisons between patient factors, phenotype, and grade of dysplasia. Results 69 patients had 423 lesions. The mean age of the study population was 48.2 years. 62.3% were male and 46.4% of patients were black. 47.8% of patients were HIV positive and 39.1% were men who have sex with men (MSM). WZB117 clinical trial There were 176 (41.6%) flat lesions and 234 (55.3%) exophytic lesions. Exophytic lesions were 2.5-fold more likely to be associated with a higher grade of dysplasia than flat lesions (OR=2.63, 95% CI 1.09-6.32). Neither lesion type nor dysplasia severity was associated with HPV, lesion location, or patient characteristics, including race, MSM, or HIV status. Discussion Exophytic lesions were more than twice as likely to have advanced dysplasia when compared with flat lesions. A clearer understanding of the association between gross lesion appearance and dysplasia will allow more appropriate counselling of patients and to develop better screening and treatment guidelines for anal condyloma and dysplasia. Statement of significance Some studies suggest that exophytic condylomata are of lower risk and more likely to be benign than flat lesions. This assumption may lead us to observe rather than excise these lesions or to fulgurate and not excise them completely, which could leave dysplasia undiagnosed or partially excised.In this paper we present the synthesis of mixed bifunctional compounds of T8 H8 silsesquioxane and spherosilicate (HSiMe2 O)8 Si8 O12 derivatives via platinum-catalyzed hydrosilylation of alkenylgermanes and olefins. To the best of our knowledge, this is the first literature example of bifunctional compounds with organogermyl functionalities. Eleven mixed systems with a variety of substituents (Si-H, alkyl, germyl, epoxy, and hydroxy) were prepared and fully characterized by NMR spectroscopy. Additionally, our research includes a real-time FT-IR study of the synthesis of these bifunctional compounds of the general formula (R)8-m (GeR'3 (CH2 )n+2 R)m Si8 O12 . and (R''(CH2 )2 R)8-m (GeR'3 (CH2 )2 R)m Si8 O12 where m∼4.The 2020 virtual issue of the Health Information and Libraries Journal (HILJ) is published to link to the CILIP Health Libraries Group Conference which was to take place in Scotland 22-25th July. Whilst the conference was postponed in light of the coronavirus (COVID-19) pandemic, its themes of (i) Working in Partnership; (ii) Resilience and Well-being; (iii) Public and Patient involvement; (iv) Quality Impact and Metrics; and (v) Improvement and Innovation have nevertheless provided the basis on which to compile this virtual issue. Overarching these themes is a core value of the HIL profession, to provide relevant, timely and sustainable information services, and the articles selected from HILJ (2018 through to March 2020) contribute to the aim of meeting and going beyond these goals under the conference banner of 'not your average day in the office'. The virtual issue mirrors the format of a regular issue of HILJ, a review article, four original articles and three from our regular features 'Dissertations into Practice', 'International Perspectives and Initiatives' and 'Teaching and Learning in Action'. The authors come from Canada, China, Croatia, Sweden and the UK. All articles included in this issue are available online.Cobalt sulfides have been popularly used in energy storage because of their high theoretical capacity and abundant redox reactions. However, poor reaction kinetics, rapid capacity decay, and severe polarization owing to volume changes during electrochemical reaction are still huge challenges for cobalt sulfides in practical applications. Herein, cobalt sulfide yolk-shell spheres were synthesized by phosphorus doping (P-CoS) to stabilize the structure of cobalt sulfides and improve their electronic/ion conductivity. Kinetic tests and density functional theory calculations confirm that the introduction of phosphorus into cobalt sulfides greatly reduces the diffusion barrier of Li+ in the intrinsic structure, thereby improving the reaction kinetics of electrode materials during the Li+ insertion/extraction process. In consequence, the P-CoS electrode delivers a high lithium storage capacity (781 mAh g-1 after 100 cycles at 0.2 A g-1 ), excellent rate capability (489 mAh g-1 at 10 A g-1 ), and outstanding cycling stability (no significant capacity decay over 4000 cycles at 5 A g-1 ). Especially for sodium-ion battery application, the P-CoS electrode expresses a striking capacity of approximately 260 mAh g-1 at 2 A g-1 after 900 cycles.Aims This study investigated real-world short-term clinical outcomes in adults with type 2 diabetes (T2D) who initiated semaglutide in a specialist endocrinology practice in Canada. Materials and methods This study was a retrospective observational study using data from the Canadian LMC Diabetes Registry. Adults with T2D who were naïve to glucagon-like peptide-1 receptor agonist (GLP-1 RA) therapy, initiated semaglutide therapy as usual standard of care between February 2018 and February 2019, and maintained semaglutide therapy during follow-up, were eligible for analysis. The primary outcome was mean change in HbA1c at three to six-month follow-up. Results In the final analytic cohort (n=937), there was a statistically significant reduction in HbA1c (%) of -1.03 ± 1.24% (mean ± SD) (p less then 0.001) and weight of -3.9 ± 4.0 kg (p less then 0.001), with no significant change in self-reported incidence of hypoglycemia. There was a significant reduction in HbA1c and weight regardless of number of co-therapies or semaglutide dose. However, adults using the 1.0 mg dose had a significantly greater reduction in HbA1c compared to adults using the 0.25 to 0.5 mg dose (between group difference -0.24 ± 0.06%, p less then 0.001). Adults using basal-bolus therapy required a significantly lower median total daily dose of insulin after adding semaglutide (0.82 U/kg vs 0.93 U/kg, p less then 0.001). Conclusions This retrospective observational study demonstrated that GLP-1 RA naïve adults with T2D initiating semaglutide in a real-world clinical practice had a statistically and clinically significant reduction in HbA1c and body weight after three to six months, regardless of semaglutide dose or order of semaglutide therapy, with no significant change in reported incidence of hypoglycemia.
