Validity and reliability of the positive and negative affect scale (SPANAS) in universitiy peruvian students

 It was studied the construct validity and the reliability of the SPANAS scale in two samples of university students from Lima. Through many confirmatory factorial analyses (AFC) it was evaluated the adjustment of three competing models (one factor, two correlated factors and two orthogonal factors). This procedure wasreplicated in the two samples of universitary students.After the validity and reliability analysis were done, it was found that the two correlated factors model was better to represent the scale in both samples. Furthermore, the Positive and Negative Affect Scale proved to be reliable. In this way we have evidence ofthe presence oftwo factors which represent the positive and negative affection.

Distribution of prevalence of Strongyloides stercoralis in Peru (1981-2010): an exploratory study

Strongyloidiasis is endemic in tropical and subtropical regions of Latin America. In Peru, the impact of Strongyloides stercoralis in public health is unknown. The objective of the present study is to describe the spatial and temporal distribution of the prevalence of S. stercoralis in Peru between 1981 and 2010, and the most affected populations. A search for epidemiological  studies was performed in the database of LIPECS, LILACs, Scielo Peru, MEDLINE and Google Scholar. The studies that
reported prevalence of S. stercoralis by using any parasitological technique were included. Between 1981 and 2010, the global prevalence rate was 6.3 %. A total of 3,695 people were reported with S. stercoralis in stools during the last 30 years. From 1981 to 2001, a total of 3,013 subjects had S. stercoralis in stools that represents a global prevalence rate of 6.6 %. From 2002 to 2010,
a total of 676 subjects had S. stercoralis in stools that represents a global prevalence rate of 5.1 %. A global reduction of prevalence was noted during the last 30 years except in the Coastal region, which deserves further research. In conclusion, Stercoralis is hyperendemic in many areas of the rainforest of Peru into a lesser extent in the coast and Andean region. Future epidemiological studies should use highly sensitive diagnostic techniques for S. stercoralis larvae detection such as Modified
Baermann's Technique or Agar-plate Culture to avoid understimating parasitorsis

Evolución histórica de la Revista Peruana de Parasitología y tendencia de otras revistas de parasitología de América Latina

La Asociación de Parasitología del Perú (ASOPERA fue creada como Sociedad Peruana de Parasitología por iniciativa del Dr. Hugo Lumbreras en una sesión de almuerzo el 30 de noviembre de 1970, y el primer Consejo Directivo provisional fue presidido por el Dr. Luis Gonzales-Mugaburu, un notable parasitólogo peruano.

Visibility trend and analysis of citations of Boletín Epidemiológico (Lima) by biomedical journals (1991-2011)

There are not known bibliometric indicators of the information produced by the surveillance system in Peru. Aim: to determine the trend of downloads and the total number of citations of Boletín Epidemiológico (Lima) for biomedical journals (January 1991 - August 2011). Methods: visibility was evaluated by download statistics available at www.dge.gob.pe. Citations were searched electronically using the titles and acronyms of Boletín Epidemiológico (Lima) on Google Scholar. Additionally, we manually reviewed the reference section of 6 journals printed between 2000 and 2004, and 12 on-line journals, indexed and published between January 1991 and August 2011. Results: During the study period, Boletín Epidemiológico (Lima) was cited 89 times by 13 journals, 4 of which were international. Boletín Epidemiológico (Lima) was cited in 35 (39.3%) articles by Revista Peruana de Medicina Experimental y Salud Pública and in 20 (22.4%) articles by Revista Peruana de Epidemiología. The subjects most cited were malaria with 15 (16.8%) and dengue with 14 (15.7%) citations. The most cited sections of Boletín Epidemiológico (Lima) were epidemiological situation with 68 (76.4%) citations and editorial with 10 (11.2%) citations. During 2006, there were 23 178 downloads with an average of 469 weekly downloads and during 2007 21 441 downloads with 412 downloads per week on average. Conclusions: There is a low rate of downloads, but with a historical tendency to increase until 2009, suggesting the usefulness of the information published by Boletín Epidemiológico (Lima).
