Infecções respiratórias em crianças menores de dois anos de idade submetidas a profilaxia com palivizumabe

OBJECTIVE: To identify the viruses involved in acute respiratory tract infections and to analyze the rates of hospitalization and death in children on palivizumab prophylaxis.METHODS:Prospective cohort of 198 infants up to one year old who were born before 29 weeks of gestational age and infants under two years old with hemodynamically unstable cardiopathy or chronic pulmonary disease who received prophylactic palivizumab against severe respiratory syncytial virus infections in 2008. During the study period, in each episode of acute respiratory tract infection, nasopharyngeal aspirate was collected to identify respiratory syncytial virus, adenovirus, parainfluenza 1, 2 and 3, influenza A and B by direct immunofluorescence, rhinovirus and metapneumovirus by polymerase chain reaction preceded by reverse transcription. Data regarding hospitalization and deaths were monitored.RESULTS:Among the 198 studied infants, 117 (59.1%) presented acute respiratory tract infections, with a total of 175 episodes. Of the 76 nasopharyngeal aspirates collected during respiratory tract infections, 37 were positive, as follow: rhinovirus (75.7%), respiratory syncytial virus (18.9%), parainfluenza (8.1%), adenovirus 2 (2.7%), metapneumovirus (2.7%) and three samples presented multiple agents. Of the 198 children, 48 (24.4%) were hospitalized: 30 (15.2%) for non-infectious etiology and 18 (9.1%) for respiratory causes. Among these 18 children, one case of respiratory syncytial virus was identified. Two deaths were reported, but respiratory syncytial virus was not identified.CONCLUSIONS:During the prophylaxis period, low frequency of respiratory syncytial virus infections and low rates of hospitalization were observed, suggesting the benefit of palivizumab prophylaxis.OBJETIVO:Identificar los virus implicados en los cuadros de infecciones agudas de trato respiratorio y analizar las tasas de internación y de óbito en niños sometidos a la profilaxis con palivizumabe.MÉTODOS:Cohorte prospectiva con 198 niños con menos de un año nacidas antes de 29 semanas de edad gestacional y niños con menos de dos años con cardiopatía hemodinámicamente inestable o enfermedad pulmonar crónica que recibieron palivizumabe para profilaxis contra infecciones graves por el virus sincitial respiratorio, en 2008. En el periodo de estudio, en cada episodio de infección aguda del trato respiratorio, se recogió aspirado de nasofaringe para identificar virus sincitial respiratorio, adenovirus, parainfluenza 1,2 y 3, influenza A y B por técnica del anticuerpo fluorescente directa, rinovirus y metapneumovirus por reacción en cadena de la polimerasa precedida por transcriptasa inversa. Se monitorean internaciones y óbitos en ese grupo.RESULTADOS:De los 198 niños seguidos, 117 (59,1%) presentaron infecciones agudas de trato respiratorio, totalizando 175 episodios.

Prophylactic treatment of infection by the sincycial respiratory virus: prospective clinical study of infants to the use of palivizumab

Respiratory Syncytial Virus (RSV) is the most important etiologic agent in acute lower respiratory tract infections (ALRTIs) in children under two years, with high rates of hospitalization and death in high risk children for severe RSV infection. Objective: To identify the virus present in acute respiratory tract infections (ARTIs) and to analyze rates of hospitalization and death in children who received palivizumab prophylaxis. Methods: Prospective cohort of 198 infants up to 1 year old born before 29 weeks gestation and infants less than two years of age with hemodynamically instable cardiopathy or chronic pulmonary disease, who received prophylactic palivizumab against severe RSV infections in 2008. During this period, a nasopharyngeal aspirate (NPA) was collected in each episode of ARTI for identification of RSV, adenovirus, parainfluenza 1, 2 and 3, influenza A and B by direct immunofluorescence, and rhinovirus and metapneumovirus for RT-PCR. Data regarding hospitalization and death were collected. Results: Of the 198 infants included, 117 (59,1%) presented ARTIs, with a total of 175 episodes. Of 76 NPAs collected, 35 were positive, being rhinovirus (75.7%), RSV (18.9%), parainfluenza (8.1%), adenovirus 2 (2.7%), metapneumovirus (2.7%) and 3 samples presented multiple agents. Of 48 hospitalizations, 18 presented respiratory causes, but in only one child was found RSV. None of the 2 children who died had RSV. Conclusion: During the palivizumab prophylaxis period, the frequency of RSV detected in high risk children with ARTIs and those who were hospitalized was low.O Vírus Sincicial Respiratório (VSR) é o principal agente em infecções agudas do trato respiratório inferior (IATRI) antes de dois anos, com altas taxas de internação e óbito em crianças de alto risco para infecção grave pelo VSR. Objetivo: Identificar os vírus envolvidos nos quadros de infecções agudas de trato respiratório (IATR) e analisar taxas de internação e óbito em crianças submetidas à profilaxia com palivizumabe. Métodos: Coorte prospectiva com 198 crianças menores de um ano de idade nascidas antes de 29 semanas de idade gestacional e crianças menores de 2 anos de idade com cardiopatia hemodinamicamente instável ou doença pulmonar crônica que receberam palivizumabe para profilaxia contra infecções graves pelo VSR em 2008. Nesse período, em cada episódio de IATR foi coletado aspirado de nasofaringe (NPA) para identificação de VSR, adenovírus, parainfluenza 1, 2 e 3, influenza A e B por imunofluorescência direta, e rinovírus e metapneumovírus por RT-PCR. Foram monitoradas internações e óbitos nesse grupo. Resultados: Das 198 crianças acompanhadas, 117 (59,1%) apresentaram IATR, totalizando 175 episódios. Das 76 NAPs coletadas, 37 foram positivas, encontrando-se, rinovírus em 75,7% dessas amostras, VSR (18,9%), parainfluenza (28,1%), adenovírus (2,7%), metapneumovírus (2,7%) e co-infecção em três amostras. Das 48 internações, 18 ocorreram por causa respiratória, sendo apenas 1 por VSR. Em nenhuma das duas crianças que evoluíram para óbito detectou-se o VSR. Conclusão: Na vigência de profilaxia com palivizumabe, a frequência de isolamento de VSR em crianças de alto risco com IATR e naquelas que necessitaram de internação hospitalar foi baixa.TEDEBV UNIFESP: Teses e dissertaçõe

Influence of sociodemographic and emotional factors on the relationship between self-compassion and perceived stress among men residing in Brazil during the COVID-19 pandemic

The analysis of sociodemographic and emotional factors is essential to understanding how men perceive stress and practice self-compassion. In health crises, this problem becomes an emergency for public health. This study aimed to analyze the influence of sociodemographic and emotional factors on the relationship between self-compassion and the perceived stress of men residing in Brazil during the COVID-19 pandemic. This is a nationwide cross-sectional study carried out between June and December 2020 with 1006 men who completed a semi-structured electronic questionnaire. Data were collected using the snowball technique. Perceived stress was measured by the Perceived Stress Scale (PSS-14), and self-compassion was assessed using the Self-Compassion Scale. Most men had low self-compassion (51.5%; n = 516) and a moderate level of perceived stress (60.9%; n = 613), while 15.9% (n = 170) had a high level of stress. The prevalence of men in the combined situation of low self-compassion and high perceived stress was 39.4% (n = 334). Living with friends had a higher prevalence of low self-compassion and high perceived stress. The prevalence of common mental disorders was high (54.3%). Men with low levels of self-compassion reported higher levels of perceived stress; however, this association was moderated by emotional and sociodemographic variables. These findings highlight the importance of considering individual and contextual factors in public policies promoting men’s mental health.info:eu-repo/semantics/publishedVersio

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved

Considerations and consequences of allowing DNA sequence data as types of fungal taxa

Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.Peer reviewe
