Abstract: Este trabajo trata de introducir el concepto de geodiversidad como parte de los recursos naturales, los elementos físicos que componen el paisaje, base del desarrollo de la biodiversidad y utiliza el contexto geológico y geomorfológico de la Serra do Cadeado, situada en el Norte del estado de Paraná, Sur de Brasil, para evaluar su potencial para el uso turístico de la geodiversidad a través del geoturismo. Utiliza como método de relevamiento las posibles limitaciones, el contenido, los valores, propuestas y condiciones de un conjunto de una serie de sitios geológicos situados en el área de estudio. Diferentes formas de accidentes geográficos tales como diques y escarpas, así como afloramientos geológicos identificados proporcionan una rica geodiversidad en la región que a partir de las observaciones pueden ser importantes productos [geo] turísticos, con aprovechamiento de los diferentes valores del paisaje, tales como científicos histórico, paisajístico, turístico y educativo. Los resultados indican un potencial significativo para la geodiversidad, sin embargo, el uso efectivo y la explotación puede ser limitada por las condiciones de la fragilidad, la infraestructura y el riesgo de degradación.

Abstract: consistent condom use is still a key component in the prevention of hiv/aids and other sexually transmitted infections. in this context, of particular interest are condom use patterns by medical students, especially considering the role of the latter as opinion-makers. the present article reports data on sexual behavior and its association with condom use among medical students in a private medical school in rio de janeiro state, brazil. data were collected from 643 medical students using an anonymous, self-administered questionnaire. data analysis used poisson regression with robust variance, calculating crude and adjusted prevalence ratios. most students were sexually initiated (85.3%). the most common partners in their sexual debut were their boyfriends/girlfriends (55.1%), most often in their own homes (27.0%). condoms were the main contraceptive method used at sexual debut (90.1%). in bivariate analysis, sex with a stable partner was the main factor associated with inconsistent condom use, and this association was confirmed by multivariate analyses, adjusted for age, gender, and family income (pr =1.95; 95%ci 1.47-2.57). these findings are consistent with the hypothesis that individuals with stable partnerships are less likely to perceive themselves at risk, following the supposition that the stability of the relationship protects against hiv/aids and other stis.

Abstract: Background There is a lack of consensus regarding the definition of risk factors for healthcare-associated infection (HCAI). The purpose of this study was to identify additional risk factors for HCAI, which are not included in the current definition of HCAI, associated with infection by multidrug-resistant (MDR) pathogens, in all hospitalized infected patients from the community. Methods This 1-year prospective cohort study included all patients with infection admitted to a large, tertiary care, university hospital. Risk factors not included in the HCAI definition, and independently associated with MDR pathogen infection, namely MDR Gram-negative (MDR-GN) and ESKAPE microorganisms (vancomycin-resistant Enterococcus faecium, methicillin-resistant Staphylococcus aureus, extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella species, carbapenem-hydrolyzing Klebsiella pneumonia and MDR Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter species), were identified by logistic regression among patients admitted from the community (either with community-acquired or HCAI). Results There were 1035 patients with infection, 718 from the community. Of these, 439 (61%) had microbiologic documentation; 123 were MDR (28%). Among MDR: 104 (85%) had MDR-GN and 41 (33%) had an ESKAPE infection. Independent risk factors associated with MDR and MDR-GN infection were: age (adjusted odds ratio (OR) = 1.7 and 1.5, p = 0.001 and p = 0.009, respectively), and hospitalization in the previous year (between 4 and 12 months previously) (adjusted OR = 2.0 and 1,7, p = 0.008 and p = 0.048, respectively). Infection by pathogens from the ESKAPE group was independently associated with previous antibiotic therapy (adjusted OR = 7.2, p < 0.001) and a Karnofsky index <70 (adjusted OR = 3.7, p = 0.003). Patients with infection by MDR, MDR-GN and pathogens from the ESKAPE group had significantly higher rates of inadequate antibiotic therapy than those without (46% vs 7%, 44% vs 10%, 61% vs 15%, respectively, p < 0.001). Conclusions This study suggests that the inclusion of additional risk factors in the current definition of HCAI for MDR pathogen infection, namely age >60 years, Karnofsky index <70, hospitalization in the previous year, and previous antibiotic therapy, may be clinically beneficial for early diagnosis, which may decrease the rate of inadequate antibiotic therapy among these patients.

Abstract: An isolate of Grapevine virus B (GVB), obtained by indexing Vitis labrusca and V. vinifera grapevines on the indicator LN33, was transmitted mechanically to several Nicotiana species. The virus was partially purified from N. cavicola and the coat protein estimated at 23 kDa by SDS-PAGE. In negatively stained leaf extracts of experimentally inoculated N. cavicola and N. occidentalis, flexuous particles with cross banding were observed, predominantly measuring 750-770 x 12 nm, with a modal length of 760 nm. Decoration indicated a clear, positive reaction against AS-GVB. In DAS-ELISA, GVB was detected in N. cavicola and grapevine extracts, and Western blots showed homologous and cross reaction of GVB and GVA antisera with GVB coat protein. Using specific primers for GVB, a fragment of 594 bp, comprising the coat protein gene coding for 197 amino acids, was amplified by RT-PCR with viral RNA extracted from GVB-infected N. occidentalis. The nucleotide and the deduced amino acid sequences of the coat protein gene showed high identities with Italian and Japanese isolates of GVB.
