Abstract: purpose: to verify cervical length using transvaginal ultrasonography in pregnant women between 28 and 34 weeks of gestation, correlating it with the latent period and the risk of maternal and neonatal infections. methods: 39 pregnant women were evaluated and divided into groups based on their cervical length, using 15, 20 and 25 mm as cut-off points. the latency periods evaluated were three and seven days. included were pregnant women with live fetuses and gestational age between 28 and 34 weeks, with a confirmed diagnosis on admission of premature rupture of membranes. patients with chorioamnionitis, multiple gestation, fetal abnormalities, uterine malformations (bicornus septate and didelphic uterus), history of previous surgery on the cervix (conization and cerclage) and cervical dilation greater than 2 cm in nulliparous women and 3 cm in multiparae were excluded from the study. results: a <15 mm cervical length was found to be highly related to a latency period of up to 72 hours (p=0.008). a <20 mm cervical length was also associated with a less than 72 hour latency period (p=0.04). a <25 mm cervical length was not found to be statistically associated with a 72 hour latency period (p=0,12). there was also no significant correlation between cervical length and latency period and maternal and neonatal infection. conclusion: the presence of a short cervix (<15 mm) was found to be related to a latency period of less than 72 hours, but not to maternal or neonatal infections.

Abstract:

Objective: As the literature on conventional criteria for discriminating early-onset (EO) from late-onset (LO) Alzheimer’s disease (AD) is sparse and controversial, the aim of this study was to establish a precise age at onset (AAO) criterion, by using a specific statistical procedure, and to describe the clinical characteristics of the two sub-groups. Methods: Admixture analysis was performed to establish the AAO cut-off in a multi-center study including 2000 AD patients consecutively recruited in eight Italian Memory Clinics. None of the patients were taking acetylcholinesterase inhibitors, antipsychoticor anti-depressant drugs. At the first diagnosticvisit, they were administered the Mini Mental StateExamination, the Basic and Instrumental Activities of Daily Living and the Neuropsychiatric Inventorytoassess clinical phenomenology. Results: Using a specific statistical procedure, we established that AAO that discriminated EO-from LO-AD was 66. Compared with the LO-AD group, the EO-AD group showed longer duration of illness and a higher educational level as well as less severe functional impairment and delusions. Conclusions: Differences in sociodemographic and clinical characteristics, such as duration of illness, education and delusion severity, suggested the involvement of different pathogenic processes. Additional studies are needed to further investigate the mechanisms underlying the disorder in the two sub-groups of AD patients.

Revista de Administra??o Mackenzie , 2013,
Abstract: As empresas representam uma entidade de grande poder sobre a sociedade com rela o à sustentabilidade. As decis es tomadas pelas organiza es geram impactos significativos sobre a sociedade. Nesse sentido, torna-se importante saber qual é a importancia atribuída pelos profissionais de educa o a temas como gest o ambiental e sustentabilidade, principalmente em cursos de administra o, já que eles s o o principal veículo de forma o dos futuros gestores. Essa foi a preocupa o de Costa et al. (2008), quando os autores avaliaram a importancia atribuída por professores para a área da gest o ambiental. O presente trabalho constitui-se uma extens o daquela pesquisa, à medida que se busca abordar conceitos sugeridos pelos autores, mas ainda n o contemplados. O objetivo geral é a constru o de uma escala para mensura o da importancia da abordagem socioambiental nos cursos de administra o de empresas na percep o dos docentes. O mapeamento dos constructos e sua forma de operacionaliza o foram obtidos por meio da revis o de literatura e da avalia o de pesquisadores doutores da área. Após essa primeira fase, realizou-se uma análise fatorial confirmatória, e os testes sugerem que as características psicométricas de um bom instrumento foram atingidas. A aplica o do instrumento com 100 professores mostrou que estes entendem que uma boa forma o em administra o necessita do envolvimento com quest es socioambientais. Segundo eles, os cursos de administra o n o abordam de forma satisfatória a temática socioambiental, nem incentivam a abordagem desse tema dentro da sala de aula. Além disso, há uma descren a por parte desses profissionais quanto às reais preocupa es das empresas com os temas sustentáveis. Embora a maioria tenha formado conceitos bem próximos do conceito mais usual para defini o de sustentabilidade, os aspectos econ micos, sociais e culturais n o foram citados. Finalmente, poucos indicam a forma como o conceito é tratado, ou seja, n o há men es relevantes a projetos de pesquisa e/ou de interven o organizacional.

Abstract: rotaviruses are the major pathogen for both human and animal. they affect young animals in intensive rearing and cause great economic losses. this study intended to evaluate the infectivity of porcine rotavirus maintained for 32 months at approximately 10oc. in the original stools specimens. thirty stools specimens of 1-4-week-old piglets originating from breeding farms located in the southwest region of the paraná state were selected for this study. they were randomly chosen from stools samples positive for rotavirus by polyacrylamide gel electrophoresis (page) at the time of collection. the thirty stools samples maintained for 32 months at approximately 10oc were re-tested by page and 11 out of 30 were still positive showing the integrity of the eleven bands of viral rna. to demonstrate the maintenance of viral infectivity, clarified and trypsin-treated stools specimens homogenates were inoculated in ma-104 cell cultures. after an average of 3 blind passages 5 out of 11 samples demonstrated cytophathic effect similar to that of standard simian rotavirus (sa-11). to confirm these findings, a immunofluorescent test was used and demonstrated typical cytoplasmic granular fluorescence. electron microscopy of stools samples showed that most of the virus particles were single- shelled and some were found to be in an advanced state of degradation. therefore the conclusion was that porcine rotavirus infectivity is maintained for a long period of time in stool specimens at low temperature. this certainly is an important aspect for the maintenance of viable virus in natural condition as well as for the transmission of the disease.

Abstract: the aim of this study was to compare different dna-extraction methods and selective enrichment broths for their effectiveness to detect salmonella typhimurium in artificially inoculated swine feces samples (100 cfu/g) by polymerase chain reaction. after enrichment in rappaport-vassiliadis, selenite cystine or müller-kauffmann tetrathionate, aliquots were used for dna extraction by three different methods: boiling-centrifugation, phenol-chloroform and salting-out. aliquots of extracted dna were then used as template in pcr. the selective enrichment broths had no effect on the efficiency of pcr when boiling-centrifugation and salting-out were used. on the other hand, phenol-chloroform was superior (p<0.05) when combined to rappaport-vassiliadis. considering cost and efficiency parameters, we encourage the use of müller-kauffmann tetrathionate broth in combination with boiling-centrifugation dna-extraction procedure.

Abstract: Objective: To analyze the histopathological lung findings of four fatal cases of the 2009 H1N1 influenza pandemic and their correlation with clinical and epidemiological characteristics. Methods: descriptive data from medical records of four patients who died in the Intensive Care Unit of a university hospital in 2009. Nasopharyngeal aspirate specimens were collected from the patients and were analyzed by real-time polymerase chain reaction. Lung biopsy was performed post mortem; a score of intensity for pathological changes was applied. Results: Three patients had positive real-time polymerase chain reaction (although all of them had a clinical diagnose of influenza H1N1). The main histopathological changes were: exudative diffuse alveolar damage with atelectasis; varying degrees of alveolar hemorrhage and edema, necrosis and sloughing of the respiratory epithelium in several bronchioli; and thrombus formation. One of the patients (the pregnant one) presented histopathological findings of cytomegalic inclusion. Conclusion: The pulmonary histopathological findings in patients with fatal 2009 H1N1 influenza pandemic disclosed intense alveolar damage and hemorrhage and severebronchiolitis. A co-infection with cytomegalovirus was described inthe pregnant patient.

Abstract: the mosquito (diptera: culicidae) ecology was studied in areas of serra do mar state park, state of s?o paulo, brazil. systematized biweekly human bait collections were made three times a day, for periods of 2 or 3 h each, in sylvatic and rural areas for 24 consecutive months (january 1991 to december 1992). a total of 24,943 adult mosquitoes belonging to 57 species were collected during 622 collective periods. aedes scapularis, coquillettidia chrysonotum, cq. venezuelensis, wyeomyia dyari, wy. longirostris, wy. theobaldi and wy. palmata were more frequently collected at swampy and at flooded areas. anopheles mediopunctatus, culex nigripalpus, ae. serratus, ae. fulvus, psorophora ferox, ps. albipes and the sabethini in general, were captured almost exclusively in forested areas. an. cruzii, an. oswaldoi and an. fluminensis were captured more frequently in a residence area. however, cx. quinquefasciatus was the only one truly eusynanthropic. an. cruzii and ae. scapularis were captured feeding on blood inside and around the residence, indicating that both species, malaria and arbovirus vectors respectively, may be involved in the transmission of these such diseases in rural areas.
