Analysis of Nurse and Patient Preferences for Pre-Filled Pen Devices for Self-Injection of Highly Purified Human Menopausal Gonadotropin (HP-hMG, MENOPURR

PURPOSE: This study aimed to identify the most important attributes for a gonadotropin pen as perceived by assisted reproductive technology (ART) patients and fertility nurses, and to examine how well a prototype HP-hMG (MENOPUR PATIENTS AND METHODS: This market research study incorporated a two-part survey with respondents (N=221) from Poland, Spain and the UK. Respondents included patients (n=141) who consulted a fertility specialist in the previous 2 years, and fertility nurses (n=80) who assisted in at least 75 ART cycles/year. Patients were divided into two subgroups depending on their experience with ART (experienced and naïve). Key attributes for an injection pen, as perceived by patients and nurses, were assessed via an online survey and ranked by their relative importance using Anchored Maximum Difference Scaling. After performing a dummy injection, respondents compared the attributes of an unbranded prototype pen against the key attributes identified. RESULTS: Across all survey respondents, the ability to correct the dialed dose was considered to be the most important product attribute of a gonadotropin pen. Confidence in the patient\u27s ability to inject correctly at home was also identified as a key attribute, considered by both nurses and naïve patients as extremely high. When considering the prototype pen device, almost all study respondents reported a positive experience (99%) with 72% rating it as very good . The prototype pen was perceived to possess the key attributes considered important for a gonadotropin pen by patients and nurses, including correcting the dose, the ability to self-inject safely and correctly, ease of preparation and use, and an injection which appeared to be as painless as possible. CONCLUSION: The prototype pen was found to perform well across all key attributes, especially those considered most important in gonadotropin pens, suggesting that it is a user-friendly option for patients undergoing ART

The Heteroptera (Hemiptera) of North Dakota II: Enicocephalomorpha : Enicocephalidae

The Enicocephalomorpha of North Dakota is documented with the report of the unique-headed bug, Systelloderes biceps (Say, 1832) from North Dakota for the first time. We also discuss the geographic distribution of S. biceps and Systelloderes culicis (Uhler, 1892), provide color photographs, provide diagnoses for the separation of these species from all other North American species, and designate a lectotype for S. culicis (Uhler)

Use of Silver Nanoparticles as Tougheners of Alumina Ceramics

In this work, alumina/silver composites were produced through powder techniques, which involve the combination of high energy mechanical milling combined with sintering in the presence of a liquid phase and with the idea of having ceramics with good toughness values. From mechanical characterizations, it was found that increases of the silver content in the alumina origins decrease the elastic’s modulus and flexural strength of the final composite. The fracture toughness of alumina increases from 4.2 MPam−0.5 for monolithic alumina to 10 MPam−0.5 for alumina with 2 wt% silver additions. It was determined that the reinforcement mechanism of these materials is due to the deflection of cracks owing to metallic bridges formed by the silver used as toughener material

Bosutinib plus capecitabine for selected advanced solid tumours: results of a phase 1 dose-escalation study

Background: This phase 1 study evaluated the maximum tolerated dose (MTD), safety, and efficacy of bosutinib (competitive Src/Abl tyrosine kinase inhibitor) plus capecitabine. Methods: Patients with locally advanced/metastatic breast, pancreatic, or colorectal cancers; cholangiocarcinoma; or glioblastoma received bosutinib plus capecitabine at eight of nine possible dose combinations using an ‘up-down' design to determine the toxicity contour of the combination. Results: Among 32 enrolled patients, none of the 9 patients receiving MTD (bosutinib 300 mg once daily plus capecitabine 1000 mg m−2 twice daily) experienced dose-limiting toxicities (DLTs). Overall, 2 out of 31 (6%) evaluable patients experienced DLTs (grade 3 neurologic pain (n=1); grade 3 pruritus/rash and increased alanine aminotransferase (n=1)). Most common treatment-related adverse events (AEs) were diarrhoea, nausea, vomiting, palmar-plantar erythrodysesthesia (PPE), fatigue; most frequent grade 3/4 AEs: PPE, fatigue, and increased alanine/aspartate aminotransferase. Although diarrhoea was common, 91% of affected patients experienced maximum grade 1/2 events that resolved. Best overall confirmed partial response or stable disease >24 weeks (all tumour types) was observed in 6 and 13% of patients. Conclusions: In this population of patients with advanced solid tumours, bosutinib plus capecitabine demonstrated a safety profile similar to that previously reported for bosutinib or capecitabine monotherapy; limited efficacy was observed

Density functional electronic spectrum of the CuO−6−10Cu O_{-6}^{-10} cluster and possible local Jahn-Teller distorsions in the La-Ba-Cu-O superconductor

We present a density functional theory (DFT) calculation in the generalized gradient approximation to study the possibility for the existence of Jahn-Teller (JT) or pseudo Jahn-Teller (PJT) type local distortions in the La-Ba-Cu-O superconducting system. We performed the calculation and correspondingly group theory classification of the electronic ground state of the CuO${_{6}}^{-10}$ elongated octahedra cluster, immersed in a background simulating the superconductor. Part of the motivation to do this study is that the origin of the apical deformation of the CuO${_{6}}^{-10}$ cluster is not due to a pure JT effect, having therefore a non {\it a priori} condition to remove the degeneracy of the electronic ground state of the parent regular octahedron. We present a comparative analysis of the symmetry classified electron spectrum with previously reported results using unrestricted Hartree-Fock calculations (UHF). Both the DFT and UHF calculations produced a non degenerate electronic ground state, not having therefore the necessary condition for a pure JT effect. However, the appearance of a degenerate E$_{g}$ state near to the highest occupied molecular orbital in the DFT calculation, suggests the possibility for a PJT effect responsible for a local distortion of the oxidized CuO$_{6}^{-9}$ cluster.Comment: 12 pages, 3 figures, submitted to International Journal of Modern Physics B (IJMPB

Recommendations for vaccination in patients with multiple sclerosis who are eligible for immunosuppressive therapies: Spanish consensus statement

Esclerosis múltiple; Vacunación; ConsensoEsclerosi múltiple; Vacunació; ConsensMultiple sclerosis; Vaccination; ConsensusAntecedentes La reciente aparición de terapias de alta efectividad para el tratamiento de la esclerosis múltiple (EM), con potencial riesgo de complicaciones infecciosas, obliga plantear estrategias de prevención y minimización de riesgos. La vacunación constituye una parte esencial del manejo de estos pacientes. Este consenso recoge una serie de pautas y escenarios prácticos de vacunación en pacientes adultos con EM candidatos a tratamiento inmunosupresor. Metodología Se llevó a cabo un consenso de tipo formal. Tras definir el alcance del documento, se realizó una búsqueda bibliográfica de vacunación en pacientes con EM, así como guías de vacunación específicas de pacientes inmunosuprimidos y en tratamiento biológico con otras enfermedades. Para la formulación de las recomendaciones se empleó la metodología de Modified Nominal Group Technique. Desarrollo La vacunación en pacientes candidatos a tratamiento inmunosupresor se debe plantear antes de iniciar un tratamiento inmunosupresor siempre que la situación clínica del paciente lo permita. Se recomendarán tanto aquellas indicadas en el calendario vacunal del adulto, como algunas específicas, en función de la inmunidad previa. Si ya está instaurado el tratamiento inmunosupresor las vacunas vivas atenuadas estarán contraindicadas. Para aquellas vacunas que dispongan de un correlato de protección se recomienda monitorizar la respuesta serológica transcurridos de uno a 2 meses de la última dosis.Background The recent development of highly effective treatments for multiple sclerosis (MS) and the potential risk of infectious complications require the development of prevention and risk minimisation strategies. Vaccination is an essential element of the management of these patients. This consensus statement includes a series of recommendations and practical scenarios for the vaccination of adult patients with MS who are eligible for highly effective immunosuppressive treatments. Methodology A formal consensus procedure was followed. Having defined the scope of the statement, we conducted a literature search on recommendations for the vaccination of patients with MS and specific vaccination guidelines for immunosuppressed patients receiving biological therapy for other conditions. The modified nominal group technique methodology was used to formulate the recommendations. Development Vaccination in patients who are candidates for immunosuppressive therapy should be considered before starting immunosuppressive treatment providing the patient's clinical situation allows. Vaccines included in the routine adult vaccination schedule, as well as some specific ones, are recommended depending on the pre-existing immunity status. If immunosuppressive treatment is already established, live attenuated vaccines are contraindicated. For vaccines with a correlate of protection, it is recommended to monitor the serological response in an optimal interval of 1-2 months from the last dose

Epidemiology of pertussis in two Ibero-American countries with different vaccination policies: lessons derived from different surveillance systems

Background Pertussis is a re-emerging disease worldwide despite its high vaccination coverage. European and Latin-American countries have used different surveillance and vaccination policies against pertussis. We compared the epidemiology of this disease in two Ibero-American countries with different vaccination and surveillance policies. Methods We compared the epidemiology of pertussis in Spain and the Dominican Republic (DR). We present a 10-year observational study of reported pertussis based on suspected and/or probable cases of pertussis identified by the national mandatory reporting system in both countries between 2005 and 2014. Both countries have a similar case definition for pertussis surveillance, although Spain applies laboratory testing, and uses real time PCR and/or culture for case confirmation while in DR only probable and/or suspected cases are reported. We analyzed incidence, hospitalization, case-fatality rates, mortality and vaccination coverage. Results The average annual incidence in children aged <1 year was 3.40/100,000 population in Spain and 12.15/100,000 in DR (p = 0.01). While the incidence in DR was generally higher than in Spain, in 2011 it was six times higher in Spain than in DR. The highest infant mortality in Spain was 0.017/100,000 in 2011, and the highest in DR was 0.08/100,000 in 2014 (p = 0.01). The proportion of hospitalized cases per year among children <1 year varied between 22.0% and 93.7% in Spain, and between 1.1% and 29.4% in DR (p = 0.0002), while mortality varied from 0 to 0.017 and 0 to 0.08 per 100,000 population in Spain and DR, respectively (p = 0.001). Vaccination coverage was 96.5% in Spain and 82.2% in DR (p = 0.001). Conclusions Pertussis is a public health problem in both countries. Surveillance, prevention and control measures should be improved, especially in DR. Current vaccination programs are not sufficient for preventing continued pertussis transmission, even in Spain which has high vaccination coverag

Post-Translational Modifications Modulate Ligand Recognition by the Third PDZ Domain of the MAGUK Protein PSD-95

The relative promiscuity of hub proteins such as postsynaptic density protein-95 (PSD-95) can be achieved by alternative splicing, allosteric regulation, and post-translational modifications, the latter of which is the most efficient method of accelerating cellular responses to environmental changes in vivo. Here, a mutational approach was used to determine the impact of phosphorylation and succinimidation post-translational modifications on the binding affinity of the postsynaptic density protein-95/discs large/zonula occludens-1 (PDZ3) domain of PSD-95. Molecular dynamics simulations revealed that the binding affinity of this domain is influenced by an interplay between salt-bridges linking the α3 helix, the β2–β3 loop and the positively charged Lys residues in its high-affinity hexapeptide ligand KKETAV. The α3 helix is an extra structural element that is not present in other PDZ domains, which links PDZ3 with the following SH3 domain in the PSD-95 protein. This regulatory mechanism was confirmed experimentally via thermodynamic and NMR chemical shift perturbation analyses, discarding intra-domain long-range effects. Taken together, the results presented here reveal the molecular basis of the regulatory role of the α3 extra-element and the effects of post-translational modifications of PDZ3 on its binding affinity, both energetically and dynamically.This research was supported by grants CVI-05915, from the Andalusian Regional Government (http://www.juntadeandalucia.es), BIO2009-13261-C02 and BIO2012-39922-C02, from the Spanish Ministry of Science and Innovation (http://www.idi.mineco.gob.es/portal/site​/MICINN/) and FEDER.
