Identifying Appropriate Quantitative Study Designs for Library Research
Diane Lorenzetti
Evidence Based Library and Information Practice , 2007,
Abstract: This paper is concerned with the identification of quantitative study designs suitable for library research. Identifying a researchable question and selecting a research method best suited to it are key to the successful design and execution of any research project. Each research situation is unique, and each researcher must find the method that best suits both their situation and the question at hand. Following a brief discussion of issues related to question development, the author outlines a checklist that may assist the process of selecting study designs for quantitative research projects. When faced with options in terms of study design selection, pragmatic issues such as expertise, funding, time, and access to participants may influence this decision‐making process.
Tratamiento biológico en psoriasis: Revisión bibliográfica
Lorenzetti,MS; Restifo,EJ;
Revista argentina de dermatolog?-a , 2012,
Abstract: the treatment of moderate to severe psoriasis is difficult, due to the variable clinical response and the adverse events emerging from the conventional systemic treatment and it is generally unsatisfactory to numerous patients. given that the currently available treatments have a suppressor and not a curative effect on the disease, the adequate signs and symptoms control requires a long-term continued treatment which, in the case of traditional systemic treatments, conveys a high risk of accumulative toxicity (hepatic-metabolic-hematic-renal failure and risk of neoplasia). phototherapy itself is limited by the fact that, generally, the patient has to visit an institution three times a week; there can be possible 8-mop toxicity and risk of neoplasia. biological psoriasis treatments are targeted against lymphocytes surface proteins or cytokines which act on the psoriasis physiopathogenic mechanisms. a bibliographic-like research was conducted to acquire international experience in biological agents, specially focused on etanercept, infliximab and adalimumab. these proved to be effective and to have a relative safety with regards to infectious and neoplastic complications.
O futuro paranaense em seu meio natural: a escrita de Domingos Nascimento e a produ o de uma identidade ao Paraná no início do século XX
Fernanda Lorandi Lorenzetti
Revista Tempo, Espa?o e Linguagem , 2010,
Abstract: This article analyzes the work of Paraná state writer DomingosNascimento in the early 20th century. I seek to understand in what way the author has tried to establish an ideal Paraná state, marked by the existence of a ‘magnificent’ natural environment, useful to progress. The author had a specific identification intent towards Paraná state, connected above all to the natural features of the state, particularly when they had economic potentials, as well as idealized territorial and populational speculation. Several proposals by Nascimento came from the fruitful context in which he was inserted, since his writing was permeated with thoughts on technicalimprovements, the evolution brought forth by machinery use, and on thedefense of progress based on rationalities and the maintenance of order.
Tratamiento biológico en psoriasis: Revisión bibliográfica Biologic therapy of psoriasis: Literature review
MS Lorenzetti,EJ Restifo
Revista Argentina de Dermatología , 2012,
Abstract: El tratamiento de la psoriasis moderada a grave es difícil, debido a la variable respuesta clínica y a los efectos adversos del tratamiento sistémico convencional, el que suele resultar insatisfactorio para numerosos pacientes. Puesto que los tratamientos actualmente disponibles tienen un efecto supresor de la enfermedad y no curativo, el control adecuado de los signos y síntomas requiere un tratamiento continuado a largo plazo, que en el caso de los tratamientos sistémicos tradicionales, conlleva un riesgo elevado de toxicidad acumulativa (da o hepático-metabólico-hemático-renal y riesgo de neoplasias). La misma fototerapia tiene sus límites por el hecho que en general, hay que concurrir tres veces por semana a una institución, la misma eventual toxicidad del 8-MOP y el riesgo de neoplasias Los tratamientos biológicos en la psoriasis van dirigidos contra citocinas o proteínas de superficie de los linfocitos, que actúan en los mecanismos fisiopatogénicos de la psoriasis. Se efectuó una investigación de tipo bibliográfica, para conocer la experiencia internacional con especial dedicación a etanercept, infliximab y adalimumab, los que demostraron ser efectivos, con una seguridad relativa respecto de complicaciones infecciosas y neoplásicas. The treatment of moderate to severe psoriasis is difficult, due to the variable clinical response and the adverse events emerging from the conventional systemic treatment and it is generally unsatisfactory to numerous patients. Given that the currently available treatments have a suppressor and not a curative effect on the disease, the adequate signs and symptoms control requires a long-term continued treatment which, in the case of traditional systemic treatments, conveys a high risk of accumulative toxicity (hepatic-metabolic-hematic-renal failure and risk of neoplasia). Phototherapy itself is limited by the fact that, generally, the patient has to visit an institution three times a week; there can be possible 8-MOP toxicity and risk of neoplasia. Biological psoriasis treatments are targeted against lymphocytes surface proteins or cytokines which act on the psoriasis physiopathogenic mechanisms.

Abstract: this article aims at analyzing the current state of research in environmental education in latin america. with emphasis on mexico and brazil, it also provides general descriptions of colombia, cuba, ecuador and venezuela. we present the limited research advances in this area, characterized by a slow process, with gradual institutional positioning on regional environmental education. the emergence of education for sustainable development, except the colombian case, did not change this process, nor created new and more favorable conditions to boost researches into a socio-political perspective. nevertheless, this article reports positive progress towards researches in environmental education. yet, spectacular results for a short to medium term are not to be expected, unless a radical change can be brought about in the current situation, which is not currently expected.
Os Trilhos do Progresso: Inten es de comunica o via estrada de ferro entre Paraná e Mato Grosso na passagem do século XIX ao XX The way of the progres: intentions of comunications through railroad between Paraná and Mato Grosso in passing of the XIX century to XX
Fernanda Lorandi Lorenzetti,Bruno Torquato Silva Ferreira
Revista de História Regional , 2009,
Abstract: O objetivo é analisar alguns projetos de engenheiros, jornalistas e políticos que visavam ligar o Estado do Paraná à Mato Grosso no período cronológico que abrange a segunda metade do século XIX até os anos iniciais do século XX. Especificamente analisar-se-á uma matéria jornalística veiculada em 1903 no jornal O Guarapuavano de autoria do jornalista e militar Luiz Cleve. Na citada reportagem o autor apresenta alguns projetos ferroviários, como por exemplo, dos engenheiros Francisco Tourinho, Beaurepaire Rohan, dos irm os Rebou as, entre outros. A t nica destes projetos, bem como da reportagem de Cleve, foi a necessidade de ligar o extremo-oeste paranaense e Mato Grosso ao Atlantico, numa tentativa de nacionalizar e civilizar essas regi es, na época, consideradas redutos de barbárie e incivilidade. The objective is to analyze a few projects of engineers, journalists and politicians whose intention was to connect the Paraná and Mato Grosso States in the period that corresponds to the second half of the 19th century to the first years of the 20th. It will be, specifically, analyzed a news article presented in 1903 on the newspaper O Guarapuavano of the journalist and military Luiz Cleve′s creation. In the article, the author presents a few railway projects, like for example, the ones of the engineers Francisco Tourinho, Beaurepaire Rohan, the Rebou as brothers, among others. The keynote of these projects, as the Cleve′s text, was the necessity of connecting the extreme-west of Paraná and Mato Grosso to the Atlantic Ocean, wishing to nationalize and civilize these regions, in times, considered full of barbarous and uncivilized happenings/behaviors.

Lorenzetti, Fabio Tadeu Moura,Chagury, Azis Arruda
International Archives of Otorhinolaryngology , 2009,
Abstract: Introduction: The association between Sleep Obstructive Apnea Syndrome (SOAS) and the obesity has been highly studied. The SOAS is characterized by the repetitive obstruction of the upper airways during the sleep, many times accompanied by snores, oxygen desaturation, sleep fragmentation and excessive daytime somnolence (EDS). Type of Study: Prospective Transversal. Objective: To analyze the results of the Berlin Questionnaire (BQ) and the Epworth Somnolence Scale (ESS) completed by the patients interned in the Spa Med Campus Sorocaba, attempting to find who has daytime somnolence and high risk for SOAS. Method: The patients completed the Berlin Questionnaire and the ESS voluntarily. The study was of transversal type with analysis of the questionnaires completed during the year of 2008. Results: We obtained a total of 276 patients with a total of 183 women and 93 men. The prevalence of obese patients was of 111 patients (40.2%). In the positive BQ group, we obtained a total of 84 patients; 34 male; as to the positive ESS group, we found a total of 67 patients, 24 male. Conclusion: The ESS and the BQ have been useful currently for selection of the sleep disorders and may serve as a possible indicator for polysonography. The questionnaires' results show us the high prevalence of individuals interned in SPA with the risk of having SOAS, specially the obese ones.

Abstract: Introdu o: A associa o entre a Síndrome de Apneia Obstrutiva do Sono (SAOS) e a obesidade tem sido muito estudada. A SAOS é caracterizada pela obstru o repetitiva da via aérea superior durante o sono, muitas vezes acompanhada de roncos, dessatura o de oxigênio, fragmenta o do sono e sonolência excessiva diurna (SED). Tipo do Estudo: Transversal Prospectivo. Objetivo: Analisar os resultados do Questionário de Berlim (QB) e da Escala de Sonolência de Epworth(ESE) preenchidos pelos pacientes internados no Spa Med Campus Sorocaba, procurando encontrar quais deles possuem sonolência diurna e alto risco para SAOS. Método: Os pacientes responderam voluntariamente aos Questionários de Berlim e ESE. O estudo foi do tipo transversal, com análise dos questionários preenchidos durante o ano de 2008. Resultados: Obtivemos um total de 276 pacientes, com um total de 183 mulheres e 93 homens. A prevalência de obesos foi de 111 pacientes (40,2%). No grupo QB positivo, obtivemos 84 pacientes no total; sendo 34 homens, quanto ao grupo ESE positivo, encontramos no total 67 pacientes, sendo 24 homens. Conclus o: A ESE e o QB têm servido atualmente de triagem para os distúrbios do sono e pode servir como possível indicador para a polissonografia. Os resultados dos questionários nos mostram a alta prevalência de indivíduos internados em SPA com risco de apresentar SAOS, especialmente os obesos.
