title: The association between vitamin D and BDNF on cognition in older adults in Southern Brazil

description: ABSTRACT OBJECTIVE To estimate the association between vitamin D and the cognitive decline of older adults and evaluate whether this association is mediated by brain-derived neurotrophic factor (BDNF) serum concentration. METHODS Cross-sectional study nested in a population-based cohort. Of the 604 participants in the complementary examination of the EpiFloripa Study, 576 older adults (60 years or older) were eligible for the study. The outcome is cognitive decline evaluated by the Mini-Mental State Examination, the exposure is vitamin D, and BDNF is the mediator. The control variables are age, sex, per capita family income, and educational level. The direct effect of vitamin D and BDNF on cognitive decline and the indirect effect mediated by BDNF was evaluated using path analysis, with the estimation of standardized coefficients. RESULTS Among the participants, we observed a direct and positive effect of vitamin D on cognitive function (Coef: 0.06; 95%CI: 0.02 to 0.11; p &lt; 0.001) and serum BDNF concentration (Coef: 21.55; 95%CI: 9.92 to 33.17; p = 0.002), i.e., the higher the vitamin D, the higher the cognitive function and serum level of BDNF. CONCLUSION There was an association between vitamin D on serum BDNF and on cognitive decline in older adults. Moreover, BDNF did not have an effect on cognitive decline, so BDNF was not a mediator of the vitamin D effect on cognitive decline.

title: Undernutrition and obesity trends in Brazilian adults from 1975 to 2019 and its associated factors

description: Nutritional status has evolved in a dual trend worldwide: underweight has become a minor or local issue while overweight or obesity has risen to play a major role in the global burden of disease. In 2014, Brazil was ranked as the third country with the highest absolute number of obese men. Our aim was to estimate trends of underweight and obesity among Brazilian adults using a comprehensive set of surveys from 1974 to 2019. The data used in the study originate from subjects aged ≥ 18 in six Brazilian national surveys, presented in chronological order: Brazilian National Survey on Household Expenses (ENDEF 1974-1975); Brazilian National Survey on Health and Nutrition (PNSN 1989); Brazilian Household Budget Survey (POF 2002-2003, 2008-2009); and Brazilian National Health Survey (PNS 2013 and 2019). All six surveys were designed to sample household complexes that were representative of the Brazilian population. Body mass index was calculated (kg/m2). The nutritional status of individuals was classified following the standards. We have modeled obesity trend according to income and education strata. The trajectories of underweight and obesity over time in Brazil draw the classical “X” of nutrition transition. From 1975 to 2019 underweight has decreased from 9.1% to 2.5% among men and 12.2% to 3.4% among women. On the other hand, obesity trajectories have scaled up from 3% to 22% among men and from 9% to 30% among women. The increase in obesity rate is directly and negatively proportional to income quintiles. Sociodemographic (income and education) improvement is associated with an increase in obesity. All public policies intending to stop the obesity spread in Brazil have been ineffective or too small to be effective.

title: Joint custody in the light of bioethics and biolaw

description: Abstract Family is the founding basis of society and the best place for the education and growth of children. Divorce is deleterious to children’s health, mainly impacting their mental health and school performance, in addition to having impacts on adulthood. Living both with the father and the mother for an equal period of time after divorce – joint custody – guarantees empirically proven benefits to the physical and psychological well-being of children. However, judicial decisions decree joint custody in less than a third of separations. By analyzing ethical and moral controversies in the interrelation of legal sciences and health sciences, biolaw makes bioethics effective. Thus, it is discussed that family lawsuits should follow multidisciplinary criteria that consider children as vulnerable subjects who need protection.

title: Earliest teredid beetle from mid-Cretaceous amber of northern Myanmar (Coleoptera: Coccinelloidea: Teredidae): new genus and species

description: ABSTRACT The earliest fossil member of Teredidae, Delteredolaemus hei Li & Cai gen. et sp. nov., is reported from mid-Cretaceous Burmese amber. Delteredolaemus is assigned to the extant tribe Teredini, and shares a generally similar morphology with the extant genus Teredolaemus Sharp, 1885, although it can be distinguished from all other members in the tribe by the shape of the pronotum and mesoventral process, as well as the anteromedially tumid metaventrite.

title: Carbon Dots from Pilosocereus gounellei for Fluorimetric Determination of Tannin in Tea Using a Flow-Batch System

description: In this study, xiquexique (Pilosocereus gounellei) native endemic cactus from the Brazilian semiarid was used for the first time as a natural carbon source (“green precursor”) for the synthesis of highly fluorescent carbon dots (CDs). These CDs were successfully used to develop a fast, low-cost, eco-friendly fluorescence method for the determination of tannins in teas. This method was automatized employing a flow-batch system coupled to an inexpensive ultraviolet light-emitting diode (UV-LED) used as an excitation source and a cheap handheld spectrometer used as a detector. CDs were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV-Vis, and fluorescence spectroscopy. The proposed method presented a linear range from 2.0-30.0 mg L-1, relative standard deviation (RSD) &lt; 3.0%, limit of detection (LOD) = 0.102 mg L-1, and recovery rates from 90.5-109.1%. A paired t-test at a 95% confidence level indicated no statistically significant difference between the proposed and reference methods, revealing that it is a useful alternative for the determination of tannins.

title: Flora of Ceará, Brazil: Rhamnaceae

description: Abstract We present the floristic-taxonomic and distribution survey of the family Rhamnaceae as part of the “Flora of Ceará: knowing to conserve” project. The survey was based on the analysis of morphological characters of specimens gathered during field expeditions and from herbaria collections, as well as the specialized literature. Rhamnaceae is represented by ten species in Ceará State belonging to five genera: Colubrina (2), Crumenaria (1), Gouania (3), Rhamnidium (1), and Sarcomphalus (3). The species were encountered in various phytophysiognomies, but especially occur in Seasonal Semideciduous Forests (Mata Seca) and the Coastal Zone Vegetation Complex (Lowland Semideciduous Forest). The species with the highest number of records was Sarcomphalus joazeiro, occurring in 62 municipalities. Seven species were encountered in 14 legally protected conservation areas in Ceará. Colubrina cordifolia, Rhamnidium molle, and Crumenaria decumbens occur exclusively in the Caatinga domain, with the first two being endemic to northeastern Brazil. Identification keys, morphological descriptions, comments on distributions, ecology, phenology, and uses of the species are provided, as well as maps and illustrations.

title: Effects of melatonin on both testicular regeneration and recovery of spermatogenesis in busulfan-treated rats

description: Abstract Testicular damage is one of the most hazardous effects of chemotherapy as it is frequently associated with oligozoospermia and azoospermia. This study aimed at evaluating the protective effect of melatonin in a rat model of busulfan-induced testicular injury. Rats were divided into four groups: control, melatonin, busulfan, busulfan plus melatonin. After 15 days, the semen was collected from the epididymis and testes were assessed. Sperm removed from cauda epididymis and analyzed for sperm count and viability. Testis tissues were also removed, fixed in formalin and were embedded in paraffin. Sections of testis tissue were stained with hematoxylin-eosin for histological examination and prepared for TUNEL (Terminal deoxynucleotide transferase dUTP Nick End Labeling) assay to detect apoptosis and PCNA (proliferating cell nuclear antigenassay) to detect proliferation cells. Serum and testes supernatants were separated to detect testosteron level and oxidative stress parameters. In histological examination, degenerative changes in seminiferous tubules were observed in the experimental groups. In biochemical examination, the total oxidant status (TOS) levels in Busulfan group were significantly higher than in the control group while the total antioxidant status (TAS) levels of all the groups were similar. In conclusion, the beneficial properties of melatonin treatment by its potent anti-oxidants may reduce adverse effects of chemotherapy in the reproductive system in a rodent system.

title: Articulations between established teachers and outsiders within the context of a teacher learning community

description: ABSTRACT The article addresses the relations between teachers considered established and those seen as outsiders within the context of a teacher learning community based on the state of São Paulo, Brazil. It seeks to understand who the subjects are as to professional teaching knowledge under a concept of practice-training induction. Based on a theoretical-methodological perspective, the researchers have produced a study case where the research subjects were also the narrators of their own perceptions, expectations and teaching actions. Holding as reference the studies of Elias and Scotson (2000); Zeichner (2008; 2015), Cochran-Smith (2012) and Nóvoa (2017), it is possible to consider that the teacher learning community reveals itself as a strategy to train subjects, where teacher learning makes teachers’ groups move toward insurgent proposals of professional performance.

title: TOWARDS A SYSTEMATIZED DIACHRONIC TERMINOLOGY: SOME BASIC CONCEPTS IN FOCUS

description: ABSTRACT Diachrony is not always an aspect discussed by terminological studies that can be based on different perspectives. Among them, Diachronic Terminology (DT), conceived as an approach that has the main characteristic of focusing on this aspect, has received more attention in recent decades by several works, whose common characteristic is the adoption of a terminologicaldiachronic approach. The diversity of these research is enormous, which and, according to Dury and Picton (2009), generates vague and imprecise theoretical and methodological contours in Terminology. To contribute to an organization of these contours in Brazilian Portuguese, since, in our country, studies (especially the theoretical ones) in this regard are still incipient, this paper presents an overview of international and national research by highlighting their main characteristics in terms of contribution and basic conceptions. Based on this panorama, the use of some terms in these studies that refer to the phenomena analyzed, and their theoretical and methodological implications are discussed. Thus, it is hoped that this work may arouse more interest in this approach and, going further, it can serve as an initial guide, as it discusses some paths that can be followed by investigations to be developed especially in Brazil.

title: Planning and Sizing of the Health Workforce in Brazil: advances and challenges

description: ABSTRACT This study aims to analyze the production of knowledge about Planning and Sizing of the Health Workforce (PDFTS) developed in Brazil, identifying models and methodologies that consider the Guidelines of the Unified Health System (SUS) for the constitution of regionalized care networks. This is an integrative review, including Brazilian studies and full text, in Portuguese, and available in the CAPES, BVS and Google Scholar databases. The searches returned 48,083 documents and, after selection with the PRISMA strategy, 62 studies published between 2011 and 2020 were included. Most of the analyzed productions approach the PDFTS with comparative analyzes between the estimated needs and the current availability, being more frequent the studies of only one professional category, with emphasis on nursing. The findings contribute to the debate on the essentiality of the health workforce for the conformation of networks, by demonstrating that the calculation methods favor the use of indicators and parameters related to the provision of services in specific health facilities, especially hospitals, not operationalizing aspects of regionalization and systemic integration of the Health Care Network.
