Objective to analyze scientific evidence on the efficacy of cloth masks in preventing COVID-19 and other respiratory infections. Method integrative literature review based on the following guiding question: What is the efficacy of cloth face masks in absorbing particles that cause respiratory infection? The search was conducted in eight electronic databases, without any restriction in terms of language or period. Results low coverage cloth face masks made of 100% cotton, scarf, pillowcase, antimicrobial pillowcase, silk, linen, tea towel, or vacuum bag, present marginal/reasonable protection against particles while high coverage cloth masks provide high protection. Conclusion cloth face masks are a preventive measure with moderate efficacy in preventing the dissemination of respiratory infections caused by particles with the same size or smaller than those of SARS-CoV-2. The type of fabric used, number of layers and frequency of washings influence the efficacy of the barrier against droplets.

Background: A recent ongoing pandemic of coronavirus disease named coronavirus disease 2019 (COVID-19) has spread in Syria from March 2020 with a pattern of a slow case increase. So far, the government has put the country under lock-down orders as a preventive measure. However, there is a considerable belief in the medical community of our country supposes that the virus has previously passed through the country depending on the high numbers of diagnosed severe respiratory infections early in 2020. Thus, this study was designed to determine the number of people with detectable antibodies to SARS-CoV-2 from two samples of healthy adults with and without a previous history of severe respiratory infection in the last 6 months of the study. Materials and Methods: To this end, samples were collected from 123 and 198 subjects with a previous severe respiratory infection and healthy controls, respectively. Then, immunoglobulin M (IgM) and IgG anti-SARS-CoV-2 antibodies were tested as well. Results: None of the samples from both groups tested IgG positive in the assay while four tested IgM samples were positive. Accordingly, these positive samples were re-analyzed and remained IgM positive in the second test although the reverse transcriptase-polymerase chain reaction for the SARS-CoV-2 virus was negative. Conclusion: Based on our findings, there is no evidence concerning the previous COVID-19 infection in Syria thus it is suggested that all isolation and lock-down orders should be respected as an effective preventive tool in this regard.

Introduction. In outpatient practice, acute nasopharyngitis in children is one of the most common reasons for seeking medical attention. The local pediatrician, as a rule, is the first to examine the child and determine the tactics of treatment. A competent approach to the choice of drugs avoids polypharmacy.The article presents the published scientific evidence on the modern approach to the treatment, as well as the author’s own clinical observation.Objective. To study the effectiveness of modern methods for the treatment of rhinopharyngitis, including the use of silver proteinate to treat acute respiratory infections in a group of frequently ill children.Materials and methods. The study involved 38 children aged 3 to 4 years, included in the group of frequent illnesses. The children were divided into 3 groups. In the first group (12 people), for four months (October-December 2019), children received symptomatic treatment of an acute respiratory infection; between episodes of acute respiratory infection, daily prophylactic irrigation of the child’s nose and throat with saline was used. In the second group (13 people), symptomatic treatment and nasal instillation of a preparation of silver proteinate were used at each episode of acute respiratory infection. In the third group (13 people), children received only symptomatic treatment for acute respiratory infection.In the first and third groups, children received symptomatic treatment of an acute respiratory infection without the use of silver proteinate.Results. The chosen approach to the ARVI treatment such as nasal instillation of silver proteinate into the bilateral nasal cavities has shown its effectiveness without having to carry out preventive measures between episodes of the disease.Conclusion. The application of elimination and antiseptic therapy with the use of Sialor for each episode of ARVI in the group of frequently ill children can reduce polypharmacy and incidence of morbidity.

Incorporation of genomic technologies into fish breeding programs is a modern reality, promising substantial advances regarding the accuracy of selection, monitoring the genetic diversity and pedigree record verification. Single nucleotide polymorphism (SNP) arrays are the most commonly used genomic tool, but the investments required make them unsustainable for emerging species, such as Arctic charr (Salvelinus alpinus), where production volume is low. The requirement to genotype a large number of animals for breeding practices necessitates cost effective genotyping approaches. In the current study, we used double digest restriction site-associated DNA (ddRAD) sequencing of either high or low coverage to genotype Arctic charr from the Swedish national breeding program and performed analytical procedures to assess their utility in a range of tasks. SNPs were identified and used for deciphering the genetic structure of the studied population, estimating genomic relationships and implementing an association study for growth-related traits. Missing information and underestimation of heterozygosity in the low coverage set were limiting factors in genetic diversity and genomic relationship analyses, where high coverage performed notably better. On the other hand, the high coverage dataset proved to be valuable when it comes to identifying loci that are associated with phenotypic traits of interest. In general, both genotyping strategies offer sustainable alternatives to hybridization-based genotyping platforms and show potential for applications in aquaculture selective breeding.

Abstract BackgroundThe identification of environmentally specific alleles and the observation of evolutional processes is a goal of conservation genomics. By generational changes of allele frequencies in populations, questions regarding effective population size, gene flow, drift, and selection can be addressed. The observation of such effects often is a trade-off of costs and resolution, when a decent sample of genotypes should be genotyped for many loci. Pool genotyping approaches can derive a high resolution and precision in allele frequency estimation, when high coverage sequencing is utilized. Still, pool high coverage pool sequencing of big genomes comes along with high costs.ResultsHere we present a reliable method to estimate a barley population’s allele frequency at low coverage sequencing. Three hundred genotypes were sampled from a barley backcross population to estimate the entire population’s allele frequency. The allele frequency estimation accuracy and yield were compared for three next generation sequencing methods. To reveal accurate allele frequency estimates on a low coverage sequencing level, a haplotyping approach was performed. Low coverage allele frequency of positional connected single polymorphisms were aggregated to a single haplotype allele frequency, resulting in two to 271 times higher depth and increased precision. We compared different haplotyping tactics, showing that gene and chip marker-based haplotypes perform on par or better than simple contig haplotype windows. The comparison of multiple pool samples and the referencing against an individual sequencing approach revealed whole genome pool resequencing having the highest correlation to individual genotyping (up to 0.97), while transcriptomics and genotyping by sequencing indicated higher error rates and lower correlations.ConclusionUsing the proposed method allows to identify the allele frequency of populations with high accuracy at low cost. This is particularly interesting for conservation genomics in species with big genomes, like barley or wheat. Whole genome low coverage resequencing at 10x coverage can deliver a highly accurate estimation of the allele frequency, when a loci-based haplotyping approach is applied. Using annotated haplotypes allows to capitalize from biological background and statistical robustness.

The objective of the present study was to identify scientific evidence in the literature regarding management and prevention of skin tears by nurses over the last ten years. This is an integrative review of articles found in the LILACS, SciELO, BDENF, MEDLINE, Scopus, ScienceDirect and PubMed databases, identified with the Portuguese, English and Spanish descriptors for "skin," "friction," or with the keyword "skin tears". After inclusion and exclusion criteria were applied, fifteen texts were selected. Scientific evidence demonstrated that the best management results are obtained by covering the tear with the skin flap itself, using octylcyanoacrylate or silicone-based products. Prevention consists of promoting a safe environment, through multidisciplinary work and health education. We conclude that it is the nursing staff's responsibility to avoid infection, trauma of any intensity, pain and bleeding.

ABSTRACT Community-acquired pneumonia (CAP) is the leading cause of death worldwide. Despite the vast diversity of respiratory microbiota, Streptococcus pneumoniae remains the most prevalent pathogen among etiologic agents. Despite the significant decrease in the mortality rates for lower respiratory tract infections in recent decades, CAP ranks third as a cause of death in Brazil. Since the latest Guidelines on CAP from the Sociedade Brasileira de Pneumologia e Tisiologia (SBPT, Brazilian Thoracic Association) were published (2009), there have been major advances in the application of imaging tests, in etiologic investigation, in risk stratification at admission and prognostic score stratification, in the use of biomarkers, and in the recommendations for antibiotic therapy (and its duration) and prevention through vaccination. To review these topics, the SBPT Committee on Respiratory Infections summoned 13 members with recognized experience in CAP in Brazil who identified issues relevant to clinical practice that require updates given the publication of new epidemiological and scientific evidence. Twelve topics concerning diagnostic, prognostic, therapeutic, and preventive issues were developed. The topics were divided among the authors, who conducted a nonsystematic review of the literature, but giving priority to major publications in the specific areas, including original articles, review articles, and systematic reviews. All authors had the opportunity to review and comment on all questions, producing a single final document that was approved by consensus.

Effect Of Chlorine

Computational density functional theory (DFT) model of the adsorption of chlorine atoms onto the perfect Al (111) surface has been performed. The structural and electronic properties of chlorine atoms adsorbed on the surface are investigated within a supercell approach for chlorine coverages of 0.25, 0.33, 0.5 and 1 ML respectively. It is found that the adsorbates prefer on-top sites over bridge, hcp and fcc sites in low coverage while fcc sites in high coverage, and the binding energy decrease with increase of coverage due to the interactions of chlorine atoms. The discussion of geometrical and electronic analysis by plotting differential charge density distribution and projected density of states (PDOS) are presented.
