Nascidos vivos com fenda palatina e labial: estudo epidemiológico
Introduction: Cleft lip and palate is a congenital malformation resulting from the inadequate fusion of bony structures during embryonic development. The etiology is multifactorial, involving genetic and environmental factors. Methodology: This study constitutes a descriptive epidemiological analysis focusing on the investigation of cases of live births with cleft lip and palate in Brazil. Data collection will be conducted through the Live Birth Information System (SINASC) during the period from 2017 to 2021. Results: The gender distribution of live births with cleft lip and palate indicates a male predominance in the sample, representing approximately 58.49% (n=4,390) of the total. Meanwhile, the percentage of female individuals is approximately 41.01% (n=3,078). The category "Unknown" has a very small representation, accounting for only 0.51% (n=38) of the sample. Conclusion: It is observed that live births with cleft lip and palate should not be overlooked. There is a significant number of cases each year, necessitating further related studies to provide solutions in society that directly benefit those affected.Introdução: A fenda labial e palatina é uma malformação congênita resultante da não fusão das estruturas ósseas adequadas durante o desenvolvimento embrionário. A etiologia é multifatorial, envolvendo fatores genéticos e ambientais. Metodologia: Este estudo constitui uma análise epidemiológica descritiva com enfoque na investigação dos casos de nascidos vivos com fenda labial e palatina no Brasil. A coleta de dados será realizada por meio do Sistema de Informações sobre Nascidos Vivos (SINASC) durante o período de 2017 a 2021. Resultado: A distribuição de gênero dos nascidos vivos com fenda labial e palatina indica que há uma maioria masculina na amostra, representando cerca de 58,49% (n= 4.390) do total. Enquanto isso, a porcentagem de pessoas do sexo feminino é de aproximadamente 41,01% (n = 3.078) A categoria "Ignorado" tem uma representação muito pequena, com apenas 0,51% (n = 38) da amostra. Conclusão: Observa-se que os nascidos vivos com fenda labial e palatina não devem ser negligenciados. Há uma quantidade significativa de nascidos por ano, sendo indispensável mais estudos relacionados, a fim de trazer soluções na sociedade que beneficiem diretamente os acometidos

Physiological stress measures in preschool children and their relationship with body composition and behavioral problems
The relationship between physiological stress measures and body composition or behavioral problems in older children remains controversial, and data in young children are lacking. The aim of the study was to investigate this relationship in predominantly healthy preschool children.
Physiological stress measures were assessed using diurnal salivary alpha-amylase (sAA) and salivary cortisol, nail cortisol and parasympathetic activation (PNS) by overnight heart rate variability, and body composition (body mass index, skinfold thickness) and behavior problems (using the Strengths and Difficulties Questionnaire) in 324 children aged 2-6 years of the SPLASHY study.
Parasympathetic nervous system was inversely related to body fat, to emotional, and to peer problems. Diurnal sAA was related to hyperactivity problems and moderated the relationship of cortisol and hyperactivity problems. Cortisol was not related to any other health problems.
The relationship of PNS with body composition and behavioral problems might highlight the protective role of the parasympathetic system early in life
Fish larvae assemblages in two floodplain lakes with different degrees of connection to the Paraná River, Brazil
The objective of this study was to assess the abundance, attributes of assemblages, and spatial and temporal distributions of fish larvae and their relationships with some abiotic variables in two floodplain lakes with different degrees of connection to the Paraná River in Ilha Grande National Park, PR, Brazil. Four sampling sites were chosen, two in each floodplain lake. Night samples were taken with plankton nets during three spawning seasons (monthly, from October to March) from 2001 to 2005. The highest diversity and abundance were recorded at Saraiva Lake, with 25 taxa being identified. In Xambrê Lake, only sedentary species were captured, and the most abundant species were Plagioscion squamosissimus and Hypophthalmus edentatus. The greatest abundance of larvae was found in the second spawning season. In the Saraiva Lake, the most abundant species were Moenkhausia aff. intermedia, Hyphessobrycon sp., and Bryconamericus stramineus, but larvae of known migratory species were also documented. In this lake, the greatest abundance of larvae was found in the third spawning. Larvae abundance was influenced by water temperature and conductivity. The high diversity and abundance recorded in Saraiva Lake may be a result of its connectivity with the Paraná River, and the low diversity and abundance observed at Xambrê Lake are likely due to its isolation from the river. This work shows the importance of these lagoons for fish development, for both sedentary and migratory species. Both lagoons may be considered to have extreme ecological importance and they are also extremely susceptible to impacts, so any careless disturbance may cause irreversible damage
