Panorama global da anquiloglossia em recém-nascidos: uma análise bibliométrica

This study aims to understand the global panorama of ankyloglossia in newborns by means of a bibliometric analysis of scientific productions up to January 2023. A search was conducted with the terms "Newborn", "Ankyloglossia" and their synonyms in the Pubmed, Embase, Cochrane, Virtual Health Library, Web of Science and Scopus platforms. After removing duplicates and applying the eligibility criteria, 431 studies were included and imported into the VOSviwer software. The most cited keywords were "Surgery" (198) and "Breastfeeding" (151). Among the 49 countries surveyed, the United States published the most on the subject (107). The most relevant study in the studied portfolio was "Ankyloglossia: assessment, incidence, and effect of frenuloplasty on the breastfeeding dyad" by Ballard and collaborators. The journal "Pediatrics" obtained the highest number of citations (608) and year 2019 recorded the most articles about ankyloglossia in newborns (44). The findings of this study show that the topic linked to oral brakes has sparked a growing interest in the scientific community, and show the concern in unveiling the real impact of ankyloglossia on the infant's breastfeeding, as well as the need to seek a consensus in diagnosis regarding surgical indication.Este trabalho buscou mapear o panorama global da anquiloglossia em recém-nascidos por meio da análise bibliométrica de produções científicas até janeiro de 2023. Para obtenção dos estudos, foi realizada uma busca avançada com os termos “Newborn”, “Ankyloglossia” e seus sinônimos nas plataformas Pubmed, Embase, Cochrane, Biblioteca Virtual de Saúde, Web of Science e Scopus. Os resultados foram importados para o gerenciador de referência Zotero. Após a remoção das duplicatas e aplicação dos critérios de elegibilidade, 431 estudos foram incluídos na análise e importados para o software VOSviwer versão 16.18. As palavras-chave mais citadas na pesquisa foram “Cirurgia” (198) e “Aleitamento” (151), que também apresentaram forte ligação entre si. Dentre os 49 países pesquisados, os Estados Unidos, o Reino Unido e a Austrália foram os que mais publicaram sobre o assunto, com 107, 44 e 28, respectivamente. O estudo mais relevante no portfólio estudado foi escrito por Ballard e colaboradores sob o título “Ankyloglossia: assessment, incidence, and effect of frenuloplasty on the breastfeeding dyad”. A revista “Pediatrics” obteve o maior número de citações (608) e ano de 2019 registrou a maior quantidade de artigos sobre a anquiloglossia em recém-nascidos (44). Os achados deste estudo demonstram que a temática ligada aos freios orais tem despertado um interesse crescente na comunidade científica e evidenciam a preocupação em desvendar o impacto real da anquiloglossia na amamentação do bebê, assim como a necessidade de buscar um consenso no diagnóstico em relação à indicação cirúrgica

Reliability of Cognitive Tests of ELSA-Brasil, the Brazilian Longitudinal Study of Adult Health

ABSTRACT Cognitive function evaluation entails the use of neuropsychological tests, applied exclusively or in sequence. The results of these tests may be influenced by factors related to the environment, the interviewer or the interviewee. Objectives: We examined the test-retest reliability of some tests of the Brazilian version from the Consortium to Establish a Registry for Alzheimer's disease. Methods: The ELSA-Brasil is a multicentre study of civil servants (35-74 years of age) from public institutions across six Brazilian States. The same tests were applied, in different order of appearance, by the same trained and certified interviewer, with an approximate 20-day interval, to 160 adults (51% men, mean age 52 years). The Intraclass Correlation Coefficient (ICC) was used to assess the reliability of the measures; and a dispersion graph was used to examine the patterns of agreement between them. Results: We observed higher retest scores in all tests as well as a shorter test completion time for the Trail Making Test B. ICC values for each test were as following: Word List Learning Test (0.56), Word Recall (0.50), Word Recognition (0.35), Phonemic Verbal Fluency Test (VFT, 0.61), Semantic VFT (0.53) and Trail B (0.91). The Bland-Altman plot showed better correlation of executive function (VFT and Trail B) than of memory tests. Conclusions: Better performance in retest may reflect a learning effect, and suggest that retest should be repeated using alternate forms or after longer periods. In this sample of adults with high schooling level, reliability was only moderate for memory tests whereas the measurement of executive function proved more reliable

Serum levels of neurotrophic factors in active toxoplasmic retinochoroiditis

Toxoplasmic retinochoroiditis (TR) is the most common identifiable cause of posterior uveitis in Brazil. Response to treatment and clinical presentation may vary significantly. We assessed serum levels of brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF), nerve growth factor (NGF), neurotrophin (NT)-3, and NT-4/5 in patients with active TR, before and after TR treatment. Methods: Twenty patients with active lesion and 15 healthy controls were enrolled in the study. Serum concentration of neurotrophic factors was determined by enzyme-linked immunosorbent assay. Results: BDNF levels were significantly higher in patients before treatment when compared with controls (p = 0.0015). There was no significant difference in pro-BDNF, NGF, GDNF, NT-3, and NT-4/5 levels between TR patients and controls. Treatment did not affect the levels of these factors. Conclusion: BDNF may be released in the context of the active TR inflammatory response. Keywords: Retinochoroiditis, Toxoplasma gondii, Brain-derived neurotrophic facto

Previous studies have demonstrated that this alkaloid is orally active at non-toxic doses. However, the mechanisms underlying its anti-inflammatory effects remain to be elucidated. This work aimed to investigate the effects of curine on macrophage activation and neutrophil recruitment. Using a murine model of lipopolysaccharide (LPS)-induced pleurisy, we demonstrated that curine significantly inhibited the recruitment of neutrophils in association with the inhibition of cytokines tumor necrosis factor (TNF-α), interleukin (IL)-1β, IL-6, monocyte chemotactic protein (CCL2/MCP-1) as well as leukotriene B4 in the pleural lavage of mice. Curine treatment reduced cytokine levels and the expression of iNOS in in vitro cultures of macrophages stimulated with LPS. Treatment with a calcium channel blocker resulted in comparable inhibition of TNF-α and IL-1β production, as well as iNOS expression by macrophages, suggesting that the anti-inflammatory effects of curine may be related to the inhibition of calcium-dependent mechanisms involved in macrophage activation. In conclusion, curine presented anti-inflammatory effects that are associated with inhibition of macrophage activation and neutrophil recruitment by inhibiting the production of inflammatory cytokines, LTB4 and nitric oxide (NO), and possibly by negatively modulating Ca2+ influx

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
