Stress experienced by professionals from basic health units in the context of the COVID-19 pandemic

OBJECTIVE: To understand stress at work among professionals in Basic Health Units, in the context of the COVID-19 pandemic. METHOD: Qualitative, exploratory and descriptive study. Data collection took place through semi-structured interviews and systematic observation. The 20 study participants were professionals from two Basic Health Units (UBS) in a municipality in the state of Bahia. The data was analyzed using IRAMUTEQ (word cloud and similarity tree) and content analysis. RESULTS: It was found that the experience of stress is something present and striking in the daily lives of health professionals at UBS due to their proximity to users and the responsibility of taking care of their health. They tend to experience frustration, instability, physical and emotional exhaustion and suffering due to the pressures of the service and the weaknesses of the health system. Fear during the COVID-19 pandemic brought anguish experienced in the work, social and family environment due to the difficulty of carrying out daily activities. They faced situations of lack of respect and empathy, risk of contamination, work overload, physical exhaustion, discrimination and isolation. FINAL CONSIDERATIONS: The stress of UBS health professionals was linked to the experience of overload in work activities, which was intensified with the biosafety measures adopted.

Climatic features in the Serra do Sincorá geopark, in Chapada Diamantina, in the state of Bahia, Brazil

Climate studies and their elements are important, because in addition to research and weather forecasting, other sectors of the community need information about weather and climate, such as agriculture, aviation, civil defense, water resources management, navigation and the energy sector. In this sense, the present study aimed to analyze the variability of some elements of the climate of the Bahian municipalities of Andaraí, Lençóis, Mucugê and Palmeiras, the area of proposition for the creation of the Serra do Sincorá Geopark, in Chapada Diamantina, based on air temperature, rainfall and evapotranspiration in the perspective of understanding the behavior of the local climate and its possible effects in the region. For this analysis, specific time intervals were selected for each municipality, available at the National Institute of Meteorology (INMET) and Climatempo. The data were tabulated for statistical analysis of the behavior of the climate elements over the months and years, using as parameters the sum, minimum, maximum, average and the correlation between the meteorological variables, with the generation of climograms and comparative graphs. The relevance of the study lies in understanding the climatic variations of the municipalities in the proposed area of the Serra do Sincorá Geopark in relation to its climatic dimension, since the results may offer subsidies regarding environmental planning, in addition to a contribution to the local population, since there are few studies in the field of climatology in the region. With the analysis of meteorological data, it is proven that the municipalities of Andaraí, Lençóis, Mucugê and Palmeiras, due to climate factors, such as altitude, latitude and longitude, on a regional scale, influence the behavior of climate elements.

Sycetta papillata sp. nov. (Porifera, Calcarea): the first record of Sycetta to the Southwestern Atlantic Ocean

Sycetta is a poorly known genus of calcareous sponges, primarily distinguished by the presence of tubes (the choanocyte chambers) radially organized around the atrial cavity and completely separated from each other. These tubes, referred to as conical diverticula or more aptly as papillae, impart a distinctive appearance to the external morphology of the sponges. Herein, we present the description of Sycetta papillata sp. nov., based on the examination of specimens collected several decades ago in the state of Bahia, located in Northeastern Brazil. The presence of a single category of diactines and atrial region formed exclusively by tetractines makes this species unique within the genus. While some species of Sycetta have been documented in deep regions, exceeding depths of 200 meters, the distribution range of S. papillata sp. nov. spans from 0.5 to 25 meters in depth. A comparative table of Sycetta species is being provided.

Ecogeographical Characterization of Passiflora cincinnata Mast. and Passiflora setacea DC. Native to the Central-Southern Mesoregion of Bahia

Passiflora cincinnata and Passiflora setacea are two native species from the northeastern semiarid region, with wide distribution in the central-southern mesoregion of the Bahia state. These species are recognized for the production of bioflavonoids. However, although they have economic relevance, little is known about ecogeographic, morphological and ecophysiological aspects. Therefore, the goal was to characterize the physiochemical and granulometric attributes of the soil as well as the edaphoclimatic conditions in 12 locations of naturally occurring Passiflora cincinnata and Passiflora setacea in the central-southern mesoregion of Bahia. The results showed environments belonging to the ecotones of the Cerrado, Caatinga and Mata Atlântica biomes. In these phytophysiognomies, the soils varied between cambisol, oxisol and planosol and presented a sandy texture and acidic pH. They also have varied ecogeographic characteristics with altitudes between 481 and 929 meters, precipitation between 478 and 1.644 millimeters and average temperature ranging between 15 and 31 degrees. Sites with average temperatures of up to 28 degrees, altitude between 670 and 860 meters, pH between 4.3 and 5.11, base saturation smaller than 50 and H+Al between 2-5 favor both species. Temperatures up to 31 degrees, pH between 5 and 6, base saturation bigger than 50 and H+Al smaller equal 1.5 favor P. cincinnata. Environments with temperatures of up to 27 degrees, altitudes above 900 meters, average pH of 4.5, average base saturation of 30 and average H+Al of 3, favors P. setacea.

Spatio-Temporal Dynamics of Center Pivot Irrigation Systems in the Brazilian Tropical Savanna (1985–2020)

The 204-million-hectare Brazilian tropical savanna (Cerrado biome), located in the central part of Brazil, constitutes the main region of food and natural fiber production in the country. An important part of this production is based on center pivot irrigation. Existing studies evaluating the spatio-temporal dynamics of center pivots in Brazil do not consider their retraction. This study aimed to evaluate the expansion and retraction of center pivots in the Cerrado biome in the period 1985–2020. We relied on the data produced by the MapBiomas Irriga project. In this period, the area occupied by center pivots increased from 47 thousand hectares in 1985 to 1.2 million hectares in 2020, mostly concentrated in the states of Minas Gerais, Goiás, São Paulo, and Bahia, confirming previous reports available in the literature. Among the 13 irrigation poles recognized by the National Water Agency (ANA), the Oeste Baiano (Bahia State) and the São Marcos (Goiás State) presented the largest areas of center pivots (173,048 ha and 101,725 ha, respectively). We also found that 76% of the center pivots are concentrated in the regions with low water availability (0.01–0.45 mm day−1). Within this 16-year period (2005–2020), more than 10% of center pivots found in 2005 were either abandoned or converted into rain-fed crop production. The results of this study can provide an important foundation for public policies directed toward the sustainable use of water resources by different consumers.

The applicability of the urine color scale in pediatric urology

To determine the level of agreement between healthcare professionals, patients and their parents/guardians in the interpretation of the urine color scale (UCS) in cases of urinary dysfunction, analyzing the applicability of the scale as a diagnostic tool determining the hydration status. This was a cross-sectional study involving 5-17-year-old patients with lower urinary tract symptoms (LUTS) and enuresis. The study was conducted in a public healthcare referral center for pediatric urology in the Brazilian state of Bahia between October 2019 and March 2020. The Kolmogorov-Smirnov test was used to assess the distribution of the variables. Agreement was assessed using the kappa coefficient and weighted kappa. The z-test was used to determine significant differences between the kappa and weighted kappa. The statistical analysis was conducted using SPSS, version 14, and significance was established at p<0.05. Forty-four patients were included. The kappa value was 32.4% (p=0.000) for the agreement between healthcare professionals and patients, 41.9% (p=0.000) for agreement between healthcare professionals and parents/guardians, and 25.0% (p=0.001) for agreement between patients and parents/guardians. The weighted kappa was 70.6% (p=0.000) for agreement between healthcare professionals and patients, 82.4% (p=0.000) for agreement between healthcare professionals and parents/guardians, and 51.5% (p=0.001) for agreement between patients and parents/guardians. There was a statistically significant difference in kappa values when the healthcare professionals were compared with the other groups. Although there were some inconsistencies in interpretation, the UCS proved to be a useful tool with which to evaluate patients' hydration status.

Is insecticide resistance a factor contributing to the increasing problems with Dalbulus maidis (Hemiptera: Cicadellidae) in Brazil?

The corn leafhopper, Dalbulus maidis, is an important pest in Brazil. While chemical control has traditionally been the cornerstone for managing this pest, field control failures have been reported for some insecticides. To understand if these failures are due to resistance, we evaluated the susceptibility of 11 field-collected populations of D. maidis to major insecticides during the 2021-2022 crop seasons in Brazil using concentration-mortality bioassays. Additionally, we employed diagnostic concentration bioassays and foliar sprays at label-recommended rates in 8-10 populations collected during the 2022-2023 crop seasons. High susceptibility to methomyl, carbosulfan and acephate was observed on concentration-mortality bioassays across all populations tested with resistance ratio (RR) based on LC50 <10-fold, except for one population from Bahia State that exhibited reduced susceptibility to methomyl (RR = 17.5). On the other hand, all populations exhibited reduced susceptibility to bifenthrin, acetamiprid, and imidacloprid, with RR ranging from 90 to 2000-fold. This reduced susceptibility to neonicotinoid and pyrethroid insecticides was further confirmed at diagnostic concentrations based on LC99 of the susceptible strain, with survival rates >20% and in foliar sprays with mortality rates <80%. Most populations exposed to acephate and carbosulfan exhibited low survival rates at diagnostic concentrations (<5%) and high mortality rates in foliar sprays (>80%). The reduced susceptibility to pyrethroid and neonicotinoid insecticides likely explain the field failures in controlling D. maidis populations in Brazil. This study represents the first large-scale susceptibility monitoring of D. maidis to insecticides, and the results will contribute to decision-making regarding the management of this pest. © 2024 Society of Chemical Industry.

Impact of age and genotype on the quality of eucalyptus wood for dissolving pulp

Wood properties for dissolving pulp production are little explored in wood quality research, mainly when it comes to eucalyptus trees. Therefore, the objective of the present study is to assess age and genotype impact on the quality of wood from young eucalyptus clones aimed at dissolving pulp production. Five trees from two clones, Eucalyptus urophylla (A) and E. urophylla x E. spp. (B), at the ages of 3 and 5 years, from crops located in Itanagra and Alagoinhas, Bahia State, Brazil, were assessed. Three wooden discs were removed from six trees at positions 0 %, 25 %, 50 %, 75 % and 100 % diameter at breast height (DBH) of the commercial height set for macroscopic characterization and wood chemical, physical and anatomical properties. Material age had impact on heartwood and bark production; and extractives, ash, xylans, galactans, arabinans rates, as well as wood vessels’ diameter and frequency. Genotypes had impact on extractives, lignin ash, hemicelluloses, xylans and galactans levels. Thus, wood chemical composition was the property most influenced by factors ‘age’ and ‘genotype’. Furthermore, clone A, at the age of 5 years, was the one with the greatest potential to dissolving pulp production, based on the following findings: the highest basic density (450 kg.m³), the highest glucans rate (48 %) and the lowest hemicellulose concentration (23 %).

Production and economic viability of ‘Kent’ mango subjected to regulated deficit irrigation in the semi-arid

Mango (Mangifera indica L.) production has great importance for Brazilian agriculture, being concentrated in the states of Bahia and Pernambuco. Although mango is a drought-tolerant crop, inadequate irrigation management reduces its yield. Thus, the objective was to evaluate production parameters and economic viability of ‘Kent’ mango subjected to controlled water deficit in the phenological stages of flowering, fruit growth and maturation. The experiment was conducted in the municipality of Petrolina/PE, semi-arid region of the São Francisco Valley, in a ultisol. The experimental design was randomized blocks, in a triple factorial scheme, with application of four irrigation depths (40, 60, 80 and 100% of crop evapotranspiration - ETc), three phenological stages (F1 - flowering, F2 - fruit growth, F3 - fruit maturation) and two production cycles (2018 and 2019 seasons), with four replicates, each of which consisting of four plants. The irrigation with 40% ETc in the flowering stage and 80% of the ETc in the growing and ripening of fruits phases promoted higher yield, water use efficiency and benefit/cost ratio in the cultivation of ‘Kent’ mango in the Brazilian semi-arid region.

Guiding seed movement: environmental heterogeneity drives genetic differentiation in Plathymenia reticulata, providing insights for restoration.

Forest and landscape restoration is one of the main strategies for overcoming the environmental crisis. This activity is particularly relevant for biodiversity-rich areas threatened by deforestation, such as tropical forests. Efficient long-term restoration requires understanding the composition and genetic structure of native populations, as well as the factors that influence these genetic components. This is because these populations serve as the seed sources and, therefore, the gene reservoirs for areas under restoration. In the present study, we investigated the influence of environmental, climatic and spatial distance factors on the genetic patterns of Plathymenia reticulata, aiming to support seed translocation strategies for restoration areas. We collected plant samples from nine populations of P. reticulata in the state of Bahia, Brazil, located in areas of Atlantic Forest and Savanna, across four climatic types, and genotyped them using nine nuclear and three chloroplast microsatellite markers. The populations of P. reticulata evaluated generally showed low to moderate genotypic variability and low haplotypic diversity. The populations within the Savanna phytophysiognomy showed values above average for six of the eight evaluated genetic diversity parameters. Using this classification based on phytophysiognomy demonstrated a high predictive power for genetic differentiation in P. reticulata. Furthermore, the interplay of climate, soil and geographic distance influenced the spread of alleles across the landscape. Based on our findings, we propose seed translocation, taking into account the biome, with restricted use of seed sources acquired or collected from the same environment as the areas to be restored (Savanna or Atlantic Forest).

Death simulation behavior of the lizard Lygodactylus klugei of the Gekkonidae (Reptilia: Squamata) family in northeastern Brazil

Natural selection favors primary defense strategies that reduce the chance of prey being spotted and discovered by a potential predator, such as camouflage, aposematism, and secondary defense strategies that include tail loss and escape, immobility, and thanatosis. The behavior of thanatosis (playing dead) or tonic immobility (body paralysis) is a strategy adopted by the prey, in which the animal simulates immobility to avoid being ingested. This simulation is effective against visually oriented predators or predators that do not feed on dead prey. Belonging to a complex of cryptic species, Lygodactylus klugei is a gecko that has a wide distribution in Northeast Brazil, occupying areas of the Caatinga and Cerrado, and that has a diurnal habit. On August 25th and September 2nd, 2021, three individuals of L. klugei were observed exhibiting thanatosis behavior during plant suppression work in the Curaçá municipality, Bahia state, Brazil. This behavior is reported for the first time in for L. klugei, and the species may use it if it is unable to escape from visually oriented predators. However, we suggest that future observations may generate new hypotheses about the benefits of this behavior in the species. Our observation adds important data to the behavioral repertoire of lizards from the Gekkonidae family, providing important natural history data to try to understand the defense mechanisms adopted by lizards in general.

New species of Argythamnia (Euphorbiaceae) restricted to Seasonal Forest of Brazil, with morphological and phylogenetic support

Argythamnia (Acalyphoideae, Euphorbiaceae) is a monophyletic genus with approximately 70 species exclusive to the New World, distributed from the southern United States to Patagonia. The greatest diversity of the genus occurs in southern North America, Central America and the Caribbean. The distribution of the genus is strongly related to seasonally dry vegetation, mainly in Seasonally Dry Tropical Forests and Woodlands in the Neotropics. Based on morphological and phylogenetic data, here we describe the eleventh species of the genus for Brazil and the fourth for the state of Bahia, where the greatest diversity of the genus in the country is concentrated. We present a description, distribution map, illustration, table with the main diagnostic characters, preliminary conservation status, palynological data, as well as the phylogenetic position for the new species.

ALFABETIZAÇÃO E LETRAMENTO: REPRESENTAÇÕES DE PROFESSORAS DO SEMIÁRIDO BAIANO PÓS-PNAIC

In the last decade, that is, between 2012 and 2022, literacy teachers in the Semiarid Zone of the State of Bahia joined the Program Literacy at the Right Age (PNAIC in Portuguese), in which the theoretical foundations of alphabetization and literacy practice have been accessed. hroughout this period, little is known about the images that remained of these foundations in teachers' narratives about their classroom practices. This study, therefore, based on the studies of intertextuality referenced by textually oriented discourse analysis (ADTO) (FAIRCLOUGH, 2001) and based on the theory of social representations (JODELET, 2001; ABRIC, 2016) aims to describe the new discursive anchors and the transformations of the concepts of alphabetization and literacy in the narratives of a group of literacy teachers trained by the PNAIC program. From these analyzes, changes in positions and knowledge will be revealed, in addition to highlighting the relevance of this type of study for the monitoring of future continuing education projects in Brazil.

Detection of encephalitis-causing viruses reveals predominance of chikungunya virus in the state of Bahia, Brazil

ObjectivesEncephalitis is a severe neurological syndrome for which herpesvirus and enteroviruses are the most common etiological agents. Arboviruses, a wildly diverse group of pathogens, are also critical epidemiological agents associated with encephalitis. In Brazil, little is known about the causative agents of encephalitis. MethodsWe conducted a hospital surveillance for encephalitis between 2020 and 2022. Molecular (RT-PCR and qPCR) and serological (virus-specific IgM and viral antigens) techniques were performed in cerebrospinal fluid and serum samples obtained from study participants. ResultsIn the 43 participants evaluated, the etiologic agent or the presence of IgM was detected in 16 (37.2%). Nine (20.9%) cases were positive for chikungunya virus (CHIKV), three (7.0%) for dengue virus, two (4.7%) for human adenovirus, one (2.3%) for varicella-zoster virus, and one (2.3%) for enterovirus. Whole-genome sequencing revealed that the CHIKV identified belongs to the East/Central/South African lineage. ConclusionHerein, CHIKV is a common pathogen identified in encephalitis cases. Our results reinforce previous evidence that chikungunya represents a significant cause of encephalitis during CHIKV outbreaks and epidemics and add to existing information on the epidemiology of encephalitis in Brazil.

Arsenic, Cadmium, and Lead Levels in School Meals and Their Risk Assessment in Municipalities in Bahia, Brazil.

School meals represent a significant supply of nutrients for children in Brazil, especially those in conditions of social vulnerability. This study aimed to assess the levels of arsenic (As), cadmium (Cd), and lead (Pb) in meals served in public elementary schools in four municipalities in the state of Bahia, Brazil, and assess the risk posed to children's health. Ninety-six samples were collected from 16 schools, freeze-dried, and subjected to microwave-assisted digestion. The As, Cd, and Pb levels were determined by graphite furnace atomic absorption spectrometry. The risk assessment was based on calculating each element's hazard quotient (HQ). None of the samples reached or exceeded the tolerable levels for the elements analyzed. Pb was the metal that obtained the most significant result, reaching maximum levels of 39-157 µg·kg-1. No element exceeded the PTWI proposed by JECFA; thus, the toxic metal content in school meals poses a negligible risk to children's health.
