Prevention of domestic accidents in childhood: knowledge of caregivers at a health care facility.

Objective: To analyze caregivers' knowledge about prevention of domestic accidents in early childhood and its association with education level.

Methods: This is a cross-sectional study conducted in a Primary Care Unit in Niterói with caregivers (convenience sample) of children under 6 years old. To classify the knowledge, we adopted the Positivity Index; to verify the association between the variable "schooling" and knowledge, the chi square test was used; statistically significant results: p < 0.

The path from suspicion to diagnosis of people with Covid-19.

Objective: To know the therapeutic itinerary of people diagnosed with Covid-19 from suspicion to the diagnosis.

Method: Qualitative research. 65 people diagnosed with Covid-19 residing in Rio de Janeiro participated.

Children with type 1 diabetes mellitus: the experience of disease.

Objective: To identify the main challenges faced by children with type 1 diabetes mellitus and describe their coping strategies.

Method: Qualitative study conducted with a semi-structured interview with children aged 8 to 11 with type 1 diabetes mellitus diagnosis who received care in the outpatient clinic of a university hospital in the state of Rio de Janeiro, Brazil. The results have been analyzed and categorized as per thematic analysis.

Child behavior during the social distancing in the COVID-19 pandemic.

Objective: To describe the daily activities performed by children from 6 to 12 years of age incomplete and analyze children's behavior during social distancing in the face of the COVID-19 pandemic.

Methods: Cross-sectional study with children in a learning stage living in Brazil. The data were collected via online form.

The therapeutic itinerary of health workers diagnosed with COVID-19.

Objective: to analyze the therapeutic itinerary of health workers diagnosed with COVID-19.

Method: qualitative study conducted with 132 health workers diagnosed with COVID-19. Data were collected using a semi-structured form sent through the social media and processed with the Interface de R pour Analyses Multidimensionnelles de Textes et de Questionnaires, according to the Descending Hierarchical Classification.

Characterization, fractionation and mobility of trace elements in surface sediments of the Jequiezinho River, Bahia, Brazil.

The Jequiezinho River is a temporary river. In the urban stretch it is impacted, with perennial flow coming from domestic sewage and rainwater. This study evaluated the geochemical distribution and potential mobility of some metals (Pb, Co, Ca, Cr, Mg, Cu, Fe, Mn, Ni and Zn) in sediments of the Jequiezinho River.

Copper and Neurotoxicity in Autism Spectrum Disorder.

Free radicals (FR) act on living organisms and present unpaired electrons in the molecular orbitals of oxygen or nitrogen species. They are classified as redox reactions and account for a wide range of processes in biological systems. Genetic and environmental factors may alter the levels of FR in the cell, leading to deleterious consequences such as membrane lipid peroxidation, protein nitration, enzyme, carbohydrate and DNA damage, ultimately resulting in premature aging and a pro-inflammatory microenvironment as observed in Alzheimer's disease (AD) and autism spectrum disorder (ASD).

Theoretical saturation in qualitative research: an experience report in interview with schoolchildren.

Objective: report the experience of applying the theoretical data saturation technique in qualitative research with schoolchildren.

Method: critical reading of primary sources and compilation of raw data, followed by thematic grouping through colorimetric codification and allocation of themes/types of statements in charts to find theoretical saturation for each grouping.

Results: colorimetric codification occurred according to previously established themes: bodily hydration; physical activities and play; handling of sickle-cell disease; feeding and clothing.

A NOVEL EPIPHYTIC CYANOBACTERIAL SPECIES FROM THE GENUS BRASILONEMA CAUSING DAMAGE TO EUCALYPTUS LEAVES(1).

A cyanobacterial mat colonizing the leaves of Eucalyptus grandis was determined to be responsible for serious damage affecting the growth and development of whole plants under the clonal hybrid nursery conditions. The dominant cyanobacterial species was isolated in BG-11 medium lacking a source of combined nitrogen and identified by cell morphology characters and molecular phylogenetic analysis (16S rRNA gene and cpcBA-IGS sequences). The isolated strain represents a novel species of the genus Brasilonema and is designated Brasilonema octagenarum strain UFV-E1.

Unusual naphthoquinones, catechin and triterpene from Byrsonima microphylla.

The new triterpene Delta1-lupenone (1), together with lupeol, beta-amyrin and betulin were isolated from the wood of Byrsonima microphylla (Malpighiaceae). The new compounds 3-hydroxy-2-methoxy-8,8,10-trimethyl-8H-antracen-1,4,5-trione (2), 3,7-dihydroxy-2-methoxy-8,8,10-trimethyl-7,8-dihydro-6H-antracen-1,4,5-trione (3), (2S*,10aR*)-2,8-dihydroxy-6-methoxy-1,1,7-trimethyl-2,3,10, 10a-tetrahydro-1H-fenantren-9-one (4) and (2S,3S)-3'-hydroxy-4',5,7-trimethoxy-flavan-3-ol (5) were also isolated through monitored TLC using the antioxidant beta-carotene reagent. The antioxidant potential of the compounds 2-5 was measured and none of them showed activity.
