title: Comparative analysis of biofilm formation by Candida albicans and Candida krusei in different types of contact lenses

description: ABSTRACT Objective: To evaluate the Candida krusei and Candida albicans biofilm formation abilities on 5 different types of contact lenses and compare their metabolic activities and biomass. Methods: After biofilm formation by both the test species, their metabolic activity was assessed by the 2,3-bis (2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide reduction assay with menadione, while the biomass was determined by staining with 0.4% crystal violet dye for further statistical analysis. Results: Both the Candida species could form biofilms on different types of contact lenses, with greater metabolic activities and lower biomass formation in rigid gas permeable lenses. Conclusion: Biofilm formation with greater metabolic activity and greater biomass were expected on soft contact lenses considering their surface hydrophobicity. However, the results demonstrated a greater metabolic activity on rigid contact lenses. This result has a great significance with regards to the increasing risk of microbial keratitis, although further studies are warranted to better elucidate the formation of biofilms on different types of contact lens materials in the future.

title: Health literacy in low- and middle-income countries: a systematic review

description: Abstract Health literacy (HL) is linked to individual capacities of access, understanding, assessment and application of health information to make decisions in everyday life, in order to maintain or improve health. The scope of this article is to review studies on HL conducted in low- and middle-income countries, with an emphasis on the definition used for HL. It involved a systematic search in the Medline, Embase, Scopus, LILACS and SciELO databases. It included studies that showed the definition of HL, studies in countries with low- and middle-income economies and Latin American studies. Initially, a selection of studies was made by reading the titles and/or abstracts. Two independent evaluators conducted the reading of the full text. Disagreements were discussed by consensus. A total of 6,025 references were located and 36 were selected for the final sample. Most studies (58.3%) were from countries on the Asian continent, followed by studies from South American countries (27.8%), including Brazil. Most studies (58.3%) evaluated the functional dimension of the HL (FHL). The most frequent definitions were from the Institute of Medicine and from the World Health Organization. Approximately 30% of the studies that evaluated FHL used broader definitions of HL as theoretical frameworks.

title: Taxonomic loss and functional reduction over time in the ichthyofauna of the Taquaruçu Reservoir, lower Paranapanema River, Southern Brazil

description: Abstract We evaluated the fish composition and ecological attributes of the ichthyofauna collected in a limnological zone of the Taquaruçu Reservoir, lower Paranapanema River. Information about the fish community was updated when compared to the previous study (2006). Non-metric multidimensional scaling (NMDS) showed differences in species composition between periods and community weighted means (CWMs) exhibited changes in functional composition over time. Four functional indices were used in the principal coordinate analysis (PcoA) to measure changes in the functional space of species, whereas functional β-diversity inspected differences in the traits composition between the periods. 1,203 individuals were sampled of 43 species, being 16 non-native and 14 new records. Compared to 2006, 27 species were absent, most of them native to Loricariidae and Anostomidae, while Curimatidae and Pimelodidae decreased in abundance. Functional indexes showed a reduction in functional diversity, whereas new species records exhibited functional redundancy. It might have occurred a simplification of the fish community over time, excluding the migratory and specialists species such as the herbivores and detritivores. Accordingly, we concluded that the ichthyofauna of the Taquaruçu Reservoir might have been undergoing a process towards biotic homogenization.

title: An alternative finite strain elastoplastic model applied to soft core sandwich panels simulation

description: Abstract An alternative elastoplastic model based on the Flory’s right Cauchy-Green stretch tensor decomposition is proposed and applied to model soft cores of sandwich panels. It does not follow usual methodologies as the additive decomposition or the Kröner-Lee multiplicative decomposition of strains. It is based on an important hyperelastic relation, Flory’s decomposition, from which the total strain is separated in two isochoric and one volumetric parts. Using this decomposition, the volumetric strain energy continues to be elastic during all elastoplastic analysis and the isochoric parts are managed to produce the plastic evolution. As a consequence of Flory’s decomposition, the plastic flow direction is known and independent of the yielding surfaces. Moreover, it provides the well known deviatoric nature of plastic strains. For validation purposes, the resulting formulation is implemented using a special 3D prismatic element in a geometrical nonlinear positional FEM computational code. The achieved numerical results are compared with literature experimental data of soft core laminated structural elements.

title: Trends in the access and use of health services in PHC among Brazilian older adults in the years 2008, 2013 and 2019

description: Abstract This paper aims to identify the conditions and trends in access and use of primary health care (PHC) services by Brazilian older adults in 2008, 2013, and 2019. We performed a cross-sectional panel study with a descriptive analysis of the percentages and confidence intervals of the variables listed, in which data on the elderly population investigated in the Health Supplement of the 2008 National Household Sample Survey (PNAD) and the 2013 and 2019 National Health Surveys (PNS) were obtained. We initially identified that, while PHC was the primary service sought for care needs, this demand tended to decline in all Brazilian regions, among older women, the 60-69 years age group, and whites. The number of households registered with the USF increased 15.2%; the search for a place, service, or health professional by 4.5%; and the population served by 31.4%. The main factors of non-attendance were not being able to get a vacancy/service ticket and doctor unavailability. A growing trend was observed among those diagnosed with Systemic Arterial Hypertension, Diabetes Mellitus, and multimorbidities among those investigated.

title: Early term ocular changes after cold compress application

description: ABSTRACT Purpose: To examine changes in the eyes after cold compress application at the early stage. Method: A total of 62 eyes from 62 healthy adult participants were included in this cross-sectional and comparative study. The subfoveal choroidal thickness and retinal nerve fiber thickness were measured by spectral-domain ocular coherence tomography. The central corneal thickness, anterior segment volume and depth, iridocorneal angle, and pupil diameter were measured by means of the Scheimpflug anterior segment imaging method. The measurements were repeated after 10 min of cold compress application, which was applied using special packs. The procedures were then repeated with non-cold packages to exclude the effect of pressure. Results: The average age of the participants was 30.74 ± 5.82 years. There was no significant change in the central corneal thickness after cold compress application, and there was a significant decrease in the anterior segment volume (p&lt;0.001), anterior segment depth (p&lt;0.001), and pupil diameter. Moreover, the iridocorneal angle increased (p=0.002). The subfoveal choroidal thickness decreased after the application of cold compress (p&lt;0.001). The overall disk thickness (p=0.034) and superior nasal scale (p=0.007) significantly decreased after the cold compress was administered during the evaluation of optic nerve fiber thickness. In contrast to that with the cold application, the subfoveal choroidal thickness and optic nerve fiber thickness did not change after the non-cold compress application (p&gt;0.05). Conclusion: Cold compress application may thus cause some physiological changes in the eyes, which necessitates the examination of its usage and effects.

title: A cascade of dams affects fish spatial distributions and functional groups of local assemblages in a subtropical river

description: Abstract Dams reduce the longitudinal connectivity of rivers and thereby disrupt fish migration and the spatial distribution of species, impacts that remain poorly studied for some Neotropical rivers from mega-diverse basins. We investigated the spatial distribution of fish species with different trophic and movement/reproductive/size characteristics to assess how functional groups have responded to a cascade of dams on the Uruguai River in southern Brazil. Fish abundance, biomass, and species composition were evaluated at eight locations along the longitudinal gradient. The fish assemblage in the upper stretch was mainly characterized by small and medium-sized species at higher trophic levels, whereas the sites located furthest downstream displayed more medium and large-sized species, including many carnivorous species. Species with high fecundity, seasonal migrants, and catfishes with internal fertilization were common in the river´s middle and lower reaches. Detritivorous species dominated areas distant from the dams. Overall, functional diversity of local fish assemblages was greater in lower reaches. The cascade of dams has impacted the distribution of functional groups of local fish assemblages of Uruguai River. The alteration of functional groups in upper reaches of the river has potential consequences for ecosystem processes and services, such as nutrient cycling and fisheries.

title: The cost of gold: Mercury contamination of fishes in a Neotropical river food web

description: Abstract In South America, mercury contamination due to gold mining operations is a threat to both biodiversity and human health. We examined mercury (Hg) concentrations in fishes that constitute important subsistence fisheries from mined and non-mined tributaries in the middle Mazaruni River, Guyana. Mercury concentrations and trophic food web structure (based on carbon and nitrogen stable isotopes) were characterized for primary basal sources and 39 fish species representing seven trophic guilds. Fishes collected at mined sites had higher mercury concentrations; piscivores and carnivores had the highest Hg concentrations and exhibited significant Hg biomagnification. Our results showed that medium- to large-bodied fishes commonly eaten by local people contained Hg values that exceed the World Health Organization (WHO) criteria, and pose a health concern for riverine communities along the Mazaruni River that depend on fish as their main source of protein. Further research to determine the sources of Hg contamination and how it affects human health in this neotropical river must become a top priority. In addition, more research on how Hg contamination impacts the fishes themselves and overall aquatic biodiversity is also needed in the Mazaruni River which has both high fish endemism and diversity.

title: Effects of sexuality on frailty and quality of life in the elderly: a cross-sectional study

description: ABSTRACT Objectives: to analyze the effects of sexuality on frailty and quality of life in the elderly. Methods: a sectional study conducted with 662 elderly people between July and October 2020. Four self-administered instruments were used to collect bio-sociodemographic variables, sexuality, frailty and quality of life. Correlation analysis and structural equation modeling were performed. Results: among the dimensions that assess sexuality, sexual intercourse had a weak, positive effect on quality of life (SC: 0.134, 95%CI: 0.153 - 0.254, p = 0.027), while affective relationships had a strong, positive effect (SC: 0.556, 95%CI: 0.442 - 0.670, p &lt; 0.001). Frailty was only significantly related to a weak to moderate negative effect with sexual intercourse (SC: -0.216, 95%CI: -0.385 - -0.047, p = 0.012). Conclusions: two dimensions of sexuality, Sexual intercourse and Affective relationships, were found to have an effect on the quality of life and frailty of the elderly people investigated.
