Introduction: Music therapy is a scientific discipline that can influence the decrease of anxiety during medical procedures. Objective: To describe the effects of music therapy on anxiety in Cuban patients undergoing tooth extraction treatment.Material and Methods: A quasi-experimental parallel-group study was conducted. Participants were randomly assigned into two groups (receiving music therapy and not receiving it during tooth extraction treatment). The Cuban version of the Modified Stomatological Treatment Anxiety Scale was used to measure anxiety before and after tooth extraction. Variables such as age, sex, presence of anxiety before and after tooth extraction, and decrease in anxiety were registered. The data were processed in RStudio, applying inferential and Bayesian statistics. Results: In this study, 155 (38.6%) participants were men and 247 (61.4%) were women, for a total of ...

Pterocarpus rohrii Vahl, conocida comúnmente como ¨charapa caspi¨ en Perú. Es un árbol de 15 a 35 m de altura que crece en bosques secos cuya madera es empleada en carpintería. Constituyendo ser una especie de importancia para los programas de reforestación. Ante el potencial maderero de esta especie es que se tomó como objetivo del presente trabajo, determinar el efecto de la de la luz en la germinación de semillas de Pterocarpus rohrii Vahl. El material biológico (frutos) procedió del Jardín Botánico de la Universidad Nacional de Trujillo. Mientras que la fase experimental se desarrolló en el Laboratorio del Instituto de papa y Cultivos Andinos. Donde se extrajo las semillas, distribuyéndose 10 grupos de 30 semillas c/u. Las cuales fueron colocadas en placas de Petri, de las cuales 5 placas fueron cubiertas con papel de aluminio. Para que finalmente tanto las placas cubi...

The aim of this study was to determine the prevalence, virulence factors (stx, eae, ehxA and astA) and phylogenetic relationships [PFGE and multilocus sequence typing (MLST)] of Shiga toxinproducing Escherichia coli (STEC) strains isolated from four previous cohort studies in 2212 Peruvian children aged ,36 months. STEC prevalence was 0.4% (14/3219) in diarrhoeal and 0.6% (15/2695) in control samples. None of the infected children developed haemolytic uraemic syndrome (HUS) or other complications of STEC. stx1 was present in 83% of strains, stx2 in 17 %, eae in 72 %, ehxA in 59% and astA in 14 %. The most common serotype was O26: H11 (14%) and the most common seropathotype was B (45 %). The strains belonged mainly to phylogenetic group B1 (52 %). The distinct combinations of alleles across the seven MLST loci were used to define 13 sequence types among 19 STEC strains. PFGE typing of 20 ...

Enterotoxigenic Escherichia coli (ETEC) is a major cause of childhood diarrhea. The present study sought to determine the prevalence and distribution of toxin types, colonization factors (CFs), and antimicrobial susceptibility of ETEC strains isolated from Peruvian children. We analyzed ETEC strains isolated from Peruvian children between 2 and 24 months of age in a passive surveillance study. Five E. coli colonies per patient were studied by multiplex real-time PCR to identify ETEC virulence factors. ETEC-associated toxins were confirmed using a GM1-based enzyme-linked immunosorbent assay. Confirmed strains were tested for CFs by dot blot assay using 21 monoclonal antibodies. We analyzed 1,129 samples from children with diarrhea and 744 control children and found ETEC in 5.3% and 4.3%, respectively. ETEC was more frequently isolated from children >12 months of age than from children <12...
