Melastatin Expression in Ocular Melanocytic Proliferations

Purpose: Melastatin (MLSN-1) belongs to the transient receptor potential (TRP) superfamilly of calcium-permeable channels, and has been reported to be a melanocyte-specific gene. In human cutaneous melanoma, MLSN-1 mRNA expression displays a pattern of inverse correlation to disease free survival. We describe the patterns of MLSN-1 mRNA expression in conjunctival nevi, conjunctival melanoma, and uveal melanoma. Methods: In situ hybridization using two S35-labelled riboprobes for MLSN-1 was performed on formalin-fixed, paraffin-embedded tissues. A control probe for H4 histone was used to confirm mRNA integrity in these archival tissues. The 21 ocular melanocytic lesions studied included 5 conjunctival nevi, 6 conjunctival melanomas, and 10 enucleated eyes with uveal melanoma. The minimal requirement for interpretation of MLSN-1 mRNA loss was the presence of only background signal in a focus of at least 5 adjacent melanocytic cells. Results: Ubiquitous expression of MLSN-1 mRNA was found in conjunctival melanocytes in the non-lesional epithelium adjacent to the conjunctival melanocytic proliferations and in all 5 conjunctival nevi studied. Four different patterns of MLSN-1 mRNA expression were observed in conjunctival melanomas: one case showed complete preservation of MLSN-1 mRNA, two cases showed diffuse scattered loss of MLSN-1 mRNA, two cases showed focal clonal loss of MLSN-1 mRNA expression, and one case had no detected MLSN-1 mRNA. In uveal melanomas, MLSN-1 mRNA expression was partially preserved in two cases, lost by a clearly delimited subset of tumor cells (focal clonal loss) in four cases, and was not detectable in the entire tumor in four cases. MLSN-1 mRNA expression was also found in the normal iris, ciliary and choroidal melanocytes as well as in the retinal pigmented epithelium and in the inner nuclear layer of the retina. Conclusions: The patterns of MLSN-1 mRNA expression in the ocular melanocytic proliferations are similar to those reported in cutaneous melanocytic proliferations. In the conjunctiva, MLSN-1 mRNA expression appeared to correlate with tumor progression; all the benign conjunctival nevi had preserved expression of MLSN-1 mRNA and most of the conjunctival melanomas partial or complete loss of expression. In uveal melanoma, patterns of melastatin expression ranging from partial preservation to complete loss were found. Additional studies of a large number of ocular melanocytic proliferations may show a correlation with tumor progression and prognosis similar to that observed in cutaneous melanoma.

Comparison of Seegene Anyplex II HPV28 with the PGMY-CHUV Assay for Human Papillomavirus Genotyping.

The Anyplex II HPV28 (H28; Seegene) is a new semiquantitative real-time multiplex PCR assay for screening and genotyping 28 human papillomaviruses (HPV) in only 2 reaction wells. H28 was compared to the PGMY-CHUV assay (PG) with 309 archival DNA samples from cervical smears collected over 8 years in our laboratory. H28 and PG were fully concordant at the genotypic level on 228 (73.8%) out of 309 samples: 27 HPV negative and 201 HPV positive. The 201 fully concordant positive samples corresponded to single infections (n = 145) and to multiple infections (2 genotypes, n = 38; 3 to 5 genotypes, n = 18). The remaining 81 samples (26.2%) were either partially concordant (n = 64, 20.7%) or fully discordant (n = 17, 5.5%). While genotype-specific agreement was nearly perfect (κ = 0.877), HPV51 was significantly less well detected by H28 and the converse was observed for HPV40, -42, -54, and -68. Sequencing of PG amplicons confirmed HPV51 discordants and suggested the involvement of a possibly local HPV51 subtype. Mismatches in the PGMY09 primers to HPV68a explained most of the HPV68 discordants, confirming the specificity of H28 toward HPV68. With PG as a reference, the sensitivity and specificity of H28 were 93.4% and 99.0%, respectively. Considering H28 as a reference, the sensitivity and specificity of PG were 83.8% and 99.6%, respectively. H28 is a very sensitive and specific HPV genotyping assay suitable for research and clinical use as an adjunct to a clinically validated test. H28 semiquantitative readout ought to be evaluated for primary cervical cancer screening.

Interhuman transmission as a potential key parameter for geographical variation in the prevalence of Pneumocystis jirovecii dihydropteroate synthase mutations.

BACKGROUND: Pneumocystis jirovecii dihydropteroate synthase (DHPS) mutations are associated with failure of prophylaxis with sulfa drugs. This retrospective study sought to better understand the geographical variation in the prevalence of these mutations. METHODS: DHPS polymorphisms in 394 clinical specimens from immunosuppressed patients who received a diagnosis of P. jirovecii pneumonia and who were hospitalized in 3 European cities were examined using polymerase chain reaction (PCR) single-strand conformation polymorphism. Demographic and clinical characteristics were obtained from patients' medical charts. RESULTS: Of the 394 patients, 79 (20%) were infected with a P. jirovecii strain harboring one or both of the previously reported DHPS mutations. The prevalence of DHPS mutations was significantly higher in Lyon than in Switzerland (33.0% vs 7.5%; P < .001). The proportion of patients with no evidence of sulfa exposure who harbored a mutant P. jirovecii DHPS genotype was significantly higher in Lyon than in Switzerland (29.7% vs 3.0%; P < .001). During the study period in Lyon, in contrast to the Swiss hospitals, measures to prevent dissemination of P. jirovecii from patients with P. jirovecii pneumonia were generally not implemented, and most patients received suboptimal prophylaxis, the failure of which was strictly associated with mutated P. jirovecii. Thus, nosocomial interhuman transmission of mutated strains directly or indirectly from other individuals in whom selection of mutants occurred may explain the high proportion of mutations without sulfa exposure in Lyon. CONCLUSIONS: Interhuman transmission of P. jirovecii, rather than selection pressure by sulfa prophylaxis, may play a predominant role in the geographical variation in the prevalence in the P. jirovecii DHPS mutations.

Longer survival for patients with alternative lengthening of telomeres (ALT) glioblastoma multiforme is due to a less aggressive phenotype and not to improved response to adjuvant therapy

Introduction: The Alternative Lengthening of Telomeres (ALT) mechanism is a significant prognostic factor for longer survival in patients with GBM, irrespective of age. The reasons for this are unknown. We considered two possibilities; firstly that ALT identifies a subset of less aggressive GBMs, or alternatively, a group of tumours that respond more favourably to adjuvant therapy. Methods: ALT was determined by staining for ALT Associated PML Bodies (APBs) in archival tissue in a retrospective analysis of 573 GBM patients. IDH1 mutation was determined by immunohistochemistry in a subset of these. Results: We identified the presence of the telomerase-independent ALT in 15% of GBM patients and found that it correlated with survival (22% of ALT patients survive more than 2 years compared to 9% for non-ALT). This survival advantage was independent of surgery type (biopsy or full resection) and treatment (radiotherapy and chemotherapy). Interestingly ALT conferred a significant survival advantage for patients who only received surgery (13.3 months compared to 5.5 months) (19% vs 1% .2 year survival). This survival benefit was also observed in GBM patients who received surgery and radiotherapy (18.5% vs 2.4%. 2 year survival), but less so for chemotherapy (21% vs 17% . 2 year survival). For the ALT patients the fraction surviving more than 2 years did not improve significantly with adjuvant therapy. IDH1 mutation also associated with ALT. Conclusions: These data indicate ALT+ tumours are biologically distinct and associated with improved patient survival, probably due to less aggressive/invasive growth. However they respond poorly to current adjuvant treatment and therefore new therapies are urgently needed for this group.

The Sustainable Debts of Philip II: A Reconstruction of Spain's Fiscal Position, 1560-1598

The defaults of Philip II have attained mythical status as the origin of sovereign debt crises. Four times during his reign the king failed to honor his debts and had to renegotiate borrowing contracts. In this paper, we reassess the fiscal position of Habsburg Spain. New archival evidence allows us to derive comprehensive estimates of debt and revenue. These show that primary surpluses were sufficient to make the king's debt sustainable in most scenarios. Spain's debt burden was manageable up to the 1580s, and its fiscal position only deteriorated for good after the defeat of the "Invincible Armada." We also estimate fiscal policy reaction functions, and show that Spain under the Habsburgs was at least as "responsible" as the US in the 20th century or as Britain in the 18th century. Our results suggest that the outcome of uncertain events such as wars may influence on a history of default more than strict adherence to fiscal rules.

Lymphatic vascular morphogenesis in development, physiology, and disease.

The lymphatic vasculature constitutes a highly specialized part of the vascular system that is essential for the maintenance of interstitial fluid balance, uptake of dietary fat, and immune response. Recently, there has been an increased awareness of the importance of lymphatic vessels in many common pathological conditions, such as tumor cell dissemination and chronic inflammation. Studies of embryonic development and genetically engineered animal models coupled with the discovery of mutations underlying human lymphedema syndromes have contributed to our understanding of mechanisms regulating normal and pathological lymphatic morphogenesis. It is now crucial to use this knowledge for the development of novel therapies for human diseases.

O grau de orientação para o mercado dos hotéis em Cabo Verde

Dada a importância do conceito de orientação para o mercado e a inexistência de estudos que estudem o seu grau de implementação nas empresas Cabo-Verdianas, este estudo visa medir o grau de orientação para o mercado dos hotéis em Cabo Verde. O estudo foi aplicado às unidades hoteleiras do sector turístico em Cabo Verde com o objectivo de: (i) determinar o grau de orientação para o mercado dos hotéis em Cabo Verde e (ii) verificar a existência de diferenças significativas no grau de orientação para o mercado dos hotéis em função da existência de departamento de marketing nos hotéis, a área funcional dos respondentes, a localização geográfica dos hotéis e a procedência do capital social maioritário. As conclusões do estudo sugerem que em termos gerais, os hotéis, em Cabo Verde, segundo as percepções dos gestores, tem um nível médio de orientação para o mercado. Os resultados mostraram ainda que apenas existe uma diferença significativa no grau de geração e resposta ao mercado, entre os hotéis nacionais e os estrangeiros. Igualmente, constatou-se que, existe uma diferença significativa, no grau de geração e disseminação de informação de mercado, entre a percepção da área comercial e ou marketing e as restantes áreas das unidades hoteleiras. Entretanto, relativamente à localização dos hotéis e à existência ou não de departamentos de marketing, não foi confirmada a existência de diferenças significativas no grau de geração, disseminação de informação e resposta ao mercado. Due to the importance given to the concept of market orientation and the lack of studies which examine its level of implementation in Cape Verdean companies, this research aims to measure the level of market orientation of hotels in Cape Verde. This study was applied to hotel units in Cape Verde with the aim of: (i) determining the level of market orientation in Cape Verde hotels and (ii) verifying the existence of significant differences in the degree of market orientation of hotels which have or not a marketing department, the professional area of the respondents, the geographic location of the hotels and the origin of the majority funds. According to the managers’ perceptions, the results suggest that in general terms, the hotels, in Cape Verde, , have an intermediate level of market orientation. The results also show that there is a significant difference between national and foreign hotels regarding information generation and responsiveness to market. In the same way, there is as significant difference on the degree of generation and dissemination of information between the functional commercial areas and the others functional hotel areas. However, there was no significant difference on what concerns generation, dissemination and market responsiveness, regarding hotels location and the existence or not of marketing departments.

Distance education in neonatal nursing scenarios: a systematic review

OBJECTIVE Identify resources that support learning mediated by technology in the field of neonatal nursing. METHOD Systematic review with searches conducted in MEDLINE, LILACS and SciELO. Titles and abstracts were independently evaluated by two experts. RESULTS Of the 2,051 references, 203 full-text articles were analyzed, resulting in the inclusion of nine studies on semiotics and semiology, cardiopulmonary resuscitation, general aspects of neonatal care, diagnostic reasoning and assessment of pain. Only two articles addressed the development of educational strategies and seven papers described the assessment of these strategies by experts and/or users. CONCLUSION Distance education is an important resource for education, and its improvement and updating, and it particularly adds advantages for neonatal nursing by approximating teaching and real-life situations and by minimizing the exposure of newborns for teaching purposes. The lack of educational initiatives mediated by technology suggests the need for the development, evaluation and dissemination of educational resources focused on nursing care of newborns and their families.

Risk sharing with the monarch: Excusable defaults and contingent debt in the age of Philip II, 1556-1598

Contingent sovereign debt can create important welfare gains. Nonetheless,there is almost no issuance today. Using hand-collected archival data, we examine thefirst known case of large-scale use of state-contingent sovereign debt in history. Philip IIof Spain entered into hundreds of contracts whose value and due date depended onverifiable, exogenous events such as the arrival of silver fleets. We show that this allowedfor effective risk-sharing between the king and his bankers. The data also stronglysuggest that the defaults that occurred were excusable they were simply contingenciesover which Crown and bankers had not contracted previously.

Strengthening the Reporting of Observational Studies in Epidemiology (STROBE): explanation and elaboration.

Much medical research is observational. The reporting of observational studies is often of insufficient quality. Poor reporting hampers the assessment of the strengths and weaknesses of a study and the generalisability of its results. Taking into account empirical evidence and theoretical considerations, a group of methodologists, researchers, and editors developed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) recommendations to improve the quality of reporting of observational studies. The STROBE Statement consists of a checklist of 22 items, which relate to the title, abstract, introduction, methods, results and discussion sections of articles. Eighteen items are common to cohort studies, case-control studies and cross-sectional studies and four are specific to each of the three study designs. The STROBE Statement provides guidance to authors about how to improve the reporting of observational studies and facilitates critical appraisal and interpretation of studies by reviewers, journal editors and readers. This explanatory and elaboration document is intended to enhance the use, understanding, and dissemination of the STROBE Statement. The meaning and rationale for each checklist item are presented. For each item, one or several published examples and, where possible, references to relevant empirical studies and methodological literature are provided. Examples of useful flow diagrams are also included. The STROBE Statement, this document, and the associated Web site (http://www.strobe-statement.org/) should be helpful resources to improve reporting of observational research.

Value and prices in Russian economic thought (1890-1920)

The subject "Value and prices in Russian economic thought (1890--1920)" should evoke several names and debates in the reader's mind. For a long time, Western scholars have been aware that the Russian economists Tugan-Baranovsky and Bortkiewicz were active participants to the Marxian transformation problem, that the mathematical models of Dmitriev prefigured forthcoming neoricardian based models, and that many Russian economists were either supporting the Marxian labour theory of value or being revisionists. Moreover, these ideas were preparing the ground for Soviet planning. Russian scholars additionally knew that this period was the time of introduction of marginalism in Russia, and that, during this period, economists were active in thinking the relation of ethics with economic theory. All these issues are well covered in the existing literature. But there is a big gap that this dissertation intends to fill. The existing literature handles these pieces separately, although they are part of a single, more general, history. All these issues (the labour theory of value, marginalism, the Marxian transformation problem, planning, ethics, mathematical economics) were part of what this dissertation calls here "The Russian synthesis". The Russian synthesis (in the singular) designates here all the attempts at synthesis between classical political economy and marginalism, between labour theory of value and marginal utility, and between value and prices that occurred in Russian economic thought between 1890 and 1920, and that embraces the whole set of issues evoked above. This dissertation has the ambition of being the first comprehensive history of that Russian synthesis. In this, this contribution is unique. It has always surprised the author of the present dissertation that such a book has not yet been written. Several good reasons, both in terms of scarce availability of sources and of ideological restrictions, may accounted for a reasonable delay of several decades. But it is now urgent to remedy the situation before the protagonists of the Russian synthesis are definitely classified under the wrong labels in the pantheon of economic thought. To accomplish this task, it has seldom be sufficient to gather together the various existing studies on aspects of this story. It as been necessary to return to the primary sources in the Russian language. The most important part of the primary literature has never been translated, and in the last years only some of them have been republished in Russian. Therefore, most translations from the Russian have been made by the author of the present dissertation. The secondary literature has been surveyed in the languages that are familiar (Russian, English and French) or almost familiar (German) to the present author, and which are hopefully the most pertinent to the present investigation. Besides, and in order to increase the acquaintance with the text, which was the objective of all this, some archival sources were used. The analysis consists of careful chronological studies of the authors' writings and their evolution in their historical and intellectual context. As a consequence, the dissertation brings new authors to the foreground - Shaposhnikov and Yurovsky - who were traditionally confined to the substitutes' bench, because they only superficially touched the domains quoted above. In the Russian synthesis however, they played an important part of the story. As a side effect, some authors that used to play in the foreground - Dmitriev and Bortkiewicz - are relegated to the background, but are not forgotten. Besides, the dissertation refreshes the views on authors already known, such as Ziber and, especially, Tugan-Baranovsky. The ultimate objective of this dissertation is to change the opinion that one could have on "value and prices in Russian economic thought", by setting the Russian synthesis at the centre of the debates.
