Abstract This article aimed to analyze how institutional racism at a Brazilian public university affects the lives of Black students. This mixed study was developed by applying an online self-administered questionnaire to university students who self-declared as Blacks. Quantitative data were analyzed using descriptive statistics, bivariate analysis using chi-square, and multinomial logistic regression. Qualitative data analysis was performed using IRAMUTEQ. Sixty-eight (54.4%) of the 125 respondents claimed to have suffered racism at least once within the university. We noticed that racist situations experienced by Black people within the university environment call into question the student’s self-confidence and motivation, directly affecting their mental health and performance in the course. The importance of receptive groups for strengthening students’ belonging was highlighted.

Resumo O objetivo do artigo foi analisar como o racismo institucional em uma universidade pública brasileira afeta a vida de estudantes negros e negras. Trata-se de um estudo misto, desenvolvido por meio da aplicação de questionário autoaplicado online a estudantes universitários que se autodeclararam negros. Os dados quantitativos foram analisados por estatística descritiva, análise bivariável por meio do qui-quadrado e regressão logística multinominal. A análise dos dados qualitativos foi feita no Iramuteq. Do total de 125 respondentes, 68 (54,4%) afirmaram ter sofrido racismo pelo menos uma vez dentro da universidade. Percebeu-se que as situações racistas vividas pelas pessoas negras dentro do ambiente universitário colocam em questão a autoconfiança e a motivação do estudante, afetando diretamente a sua saúde mental e seu desempenho no curso. Evidenciou-se a importância dos coletivos para acolhimento e fortalecimento do pertencimento dos estudantes.

Resumo O objetivo foi verificar a evolução da implementação do Núcleo Ampliado de Saúde da Família e Atenção Básica (NASF-AB) nos municípios da região Sul do Brasil, de 2008 a 2019, sob à luz da hipótese da equidade inversa. Estudo ecológico considerando 1.188 municípios do Sul do Brasil. As análises foram separadas por estado, com os municípios divididos em quartis de Índice de Desenvolvimento Humano Municipal - Renda. Foi calculado o percentual acumulativo de implementação do NASF-AB no período e a desigualdade entre Q1 (mais rico) e Q4 (mais pobre) verificada por medidas de desigualdade absoluta e relativa. No Paraná o Q1 apresentou maior cobertura do NASF-AB do que o Q4 e, apesar da desigualdade ter reduzido ao final do período, ainda estava bem demarcada, seguindo padrão “top inequality”. Em Santa Catarina ocorreu o que prevê a hipótese, com aumento das desigualdades no início e posterior redução quando já existia NASF-AB em cerca de 90% dos municípios do Q1, caracterizando “botton inequality”. No Rio Grande do Sul a hipótese foi refutada ao observar, a partir de 2014, maior implementação no Q4 em relação ao Q1.

Abstract The present study aimed to analyze the evolution of the implementation of Family Health and Primary Health Care Expanded Support Centers (NASF-AB, in Portuguese) in the municipalities of Southern Brazil, from 2008 to 2019, in light of the inverse equity hypothesis. This was an ecological study, considering 1,188 municipalities of Southern Brazil. The analyses were separated by state, with municipalities divided into quartiles of Municipal Human Development Index - Income (MHDI-Income). Our study calculated the cumulative percentage of the implementation of NASF-AB within the given period and the inequality between Q1 (richest) and Q4 (poorest), assessed by the absolute and relative inequality measures. In Paraná, Q1 presented a higher coverage of NASF-AB than did Q4, and, although the inequality had decreased at the end of the period, it was still quite distinct, according to the “top inequality” pattern. In Santa Catarina, the predictions of the hypothesis were confirmed, with inequalities found in the beginning of the period and a near 90% decline once NASF-AB had been implemented in the municipalities of Q1, characterizing the “bottom inequality” pattern. In Rio Grande do Sul, the hypothesis was refuted observing that since 2014 there was a greater implementation in Q4 as compared to Q1 was observed.

ABSTRACT BACKGROUND: Hypovitaminosis D is a public health problem associated with several chronic inflammatory and immunological diseases, including psoriasis. OBJECTIVES: This study aimed to determine the prevalence of hypovitaminosis D in patients with plaque psoriasis. A comparison was made between vitamin D levels in patients with psoriasis and those with other non-inflammatory dermatoses without photosensitivity. In addition, it evaluated the effects of the patients’ Fitzpatrick skin phototype and the season of the year on the serum levels of vitamin D. DESIGN AND SETTINGS: A retrospective cross-sectional study was conducted at an outpatient clinic in a university center in Juiz de Fora (MG), Brazil. METHODS: A review of dermatology patients’ demographic data, including skin phototype and serum levels of 25-hydroxyvitamin D [25(OH)D], over 12 months in 2016. RESULTS: This study included 554 patients: 300 patients allocated to the plaque psoriasis group and 254 control patients with other dermatological diseases. Regarding the season of the year, 229, 132, 62, and 131 participants were evaluated in summer, autumn, winter, and spring, respectively. As for the skin phototype, 397, 139, and 18 patients had phototypes III, IV, and V, respectively. The serum levels of 25(OH)D were significantly lower in the psoriasis group (24.91 ± 7.16 ng/mL) than in the control group (30.37 ± 8.14 ng/mL). CONCLUSIONS: Hypovitaminosis D (< 30 ng/mL) was present in 76.66% of patients with psoriasis versus 53.94% of control patients. Vitamin D deficiency (< 20 ng/mL) was observed in 25% of the patients with psoriasis versus 8.66% in the control group (P < 0.001). The season and patient’s skin phototype were independent predictors of serum vitamin D levels.

Abstract BACKGROUND: Psoriasis is a systemic, immune-mediated disease characterized by inflammatory manifestations in the skin and joints. Vitamin D deficiency is currently considered a pandemic and is associated with comorbidities including psoriasis and psoriatic arthritis (PsA). OBJECTIVES: To determine the prevalence of hypovitaminosis D [25(OH)D] in patients with plaque psoriasis, with and without PsA, and of independent predictors of serum 25(OH)D levels. DESIGN AND SETTING: Retrospective cross-sectional study conducted among 300 patients at an outpatient clinic in a university center in Juiz de Fora, Minas Gerais, Brazil. METHODS: Demographic and clinical data (psoriasis area and severity index [PASI], family history, age at onset, disease duration, and the presence of PsA according to Classification Criteria for Psoriatic Arthritis), skin phototype, and season of the year were reviewed. RESULTS: Hypovitaminosis D (< 30 ng/mL) was highly prevalent in patients with psoriasis with and without PsA (82.2% and 74.9%, respectively). An inverse correlation between PASI and vitamin D was found (without PsA r = –0.59 and, PsA r = –0.52, P < 0.001), and multivariate regression revealed that hypovitaminosis D was associated with disease severity, season, and phototype. It was confirmed by binary logistic regression between PASI and vitamin D deficiency (< 30 ng/mL), (odds ratio, OR 1.78 CI: –0.20–0.53, P < 0.001). CONCLUSION: Hypovitaminosis D (< 30 ng/mL) was highly prevalent in psoriatic patients with and without PsA. Season and skin phototype were associated with 25(OH)D levels. An inverse association between PASI and serum 25(OH)D levels was established.

ABSTRACT Determining what and how much each environmental factor affects pregnancy is crucial to the sustainability and management of beef cow herds. The study evaluated through logistic regression the effect of environmental variables on the increase or reduction in the pregnancy rate of beef cows. The average pregnancy rate in the cows was 73 %, with an average age for the herd of 3.7 years. An increase in age of one year represented a 30 % increase in pregnancy, while a reduction of one year reduced the odds of pregnancy in the cows by 23 %. During the lactation period, an extra seven days’ lactation reduced the odds of pregnancy by 12 %. For every seven days that weaning was brought forward, the cows’ pregnancy odds increased by 14 %. An increase of 0.1 kg in average daily gain represented an increase of 17 % and 15 % in the odds of pregnancy during the first 60 days post-partum and 60 days to the end of the reproductive period. On the other hand, the loss of 0.1 kg in average daily gain resulted in a 14 % and 13 % reduction in the cows’ pregnancy odds, respectively. Factors such as age, the precocity of calving in the calving season, the time the calf remains with the cow and better performance in cows between calving and the end of the mating are strategies that increase the chances of pregnancy in beef cows.

ABSTRACT Objective To compare the sociodemographic and clinico-functional characteristics of patients admitted to a stroke unit immediately before and during two different COVID-19 pandemic phases. Methods This exploratory study was conducted in the stroke unit of a public hospital in Brazil. Patients consecutively admitted to a stroke unit for 18 months with primary stroke aged ≥20 years were included and divided into three groups: G1: Pre-pandemic; G2: Early pandemic; and G3: Late pandemic. The sociodemographic and clinico-functional characteristics of the groups were compared (α=0.05). Results The study included 383 individuals (G1=124; G2=151; G3=108). The number of risk factors (higher in G2; p≤0.001), smoking (more common in G2; p≤0.01), type of stroke (ischemic more common in G3; p=0.002), stroke severity (more severe in G2; p=0.02), and level of disability (more severe in G2: p≤0.01) were significantly different among the groups. Conclusion A greater number of serious events and risk factors including smoking and higher level of disability was observed in patients in the beginning of the pandemic than in the late phases. Only the occurrence of ischemic stroke increased in the late phase. Therefore, these individuals may have an increased need for rehabilitation services monitoring and care during their lifespan. Additionally, these results indicate that health promotion and prevention services should be strengthened for future health emergencies.

Abstract In xeric environments, such as Caatinga Biome, habitat characteristics such as phytophysiognomy type and presence of water bodies can represent higher resource availability. In this context, the present study investigated the effect of phytophysiognomies and presence of water bodies in the abundance and community structure of medium and large mammal species (MLM) in the Serra de Santa Catarina, Paraíba, Brazil. To evaluate these variables we conduct an effort of 373 camera-trap days, between August 2012 and November 2014. We recorded 12 MLM species, distributed in six orders and 11 families. From those, Kerodon rupestris is the only one listed in the Brazilian List of Threatened Fauna. Regarding the habitat, the Mann-Whitney showed a significant higher frequency to the Shrubby habitat and the ANOSIM showed no shifts in the community structure between Arboreal and Shrubby. Concerning the presence of water bodies, both the Mann-Whitney and the ANOSIM showed significant higher frequency to the habitat with water presence. We observed that both phytophysiognomy and water bodies are important variables which affect mainly the abundance of mammalian species from semiarid environments. Nonetheless, whereas the forest remnants get smaller the existence of water bodies becomes a preponderant factor to the MLM species and its community structure.

Abstract Potential variables for the reproductive success of beef cows were evaluated. Included in the model were the age of the cow at calving; the interval between the Julian calving date and the end of the breeding season; the body weight and conditions at calving, at 75 days post-partum and at the end of the breeding season; and the mean daily variation in weight between these dates. Logistic regression was used in the analysis, with the parameters evaluated using the odds ratio statistic, estimating the chance of pregnancy. The mean rate of pregnancy was 84% and 55% for early and late-weaned cows, respectively. For early weaned cows, the regression variables were the Julian calving date, age of the cow, weight gain from calving to 75 days post-partum, and from 75 days post-partum to the end of the reproductive period. For late-weaned cows, there were only two regression variables, weight at calving and weight gain from calving to the end of the reproductive period. For every year above the average age of the herd, early weaned cows have an 80.9% greater chance of pregnancy, while a reduction of one year reduces the chance of pregnancy by 44.7%. In early weaned cows, every seven days after the mean Julian calving date reduces the chances of pregnancy by 22.6%, whereas every seven days before the mean calving date increases pregnancy by 29.2%. Greater gains in cow body weight, from calving to the end of the reproductive period, determine a greater probability of pregnancy.

ABSTRACT Objective: To map the experiences of Interprofessional Education (IPE) in Health at the São Paulo campus of the University of São Paulo. Method: This is a descriptive, exploratory study with a quantitative approach and data collection through an online questionnaire addressed to teachers from eight teaching units and 14 health courses. The data was analyzed using absolute and percentage frequencies. Results: The majority of teachers do not take part in IPE experiences (70.4%). Most of the experiences are between six and ten years old, involving up to four teachers and small groups of students, mostly extracurricular or extension activities. The teaching and assessment strategies are diverse and open to students of all years. Conclusion: IPE experiences involve a small number of students and teachers and, although consolidated in terms of the time they have been offered, are limited to extracurricular spaces. Factors such as improvements in institutional support and teacher development are pointed out as important for making progress in strengthening IPE in the analyzed context.

Objective: The process of detecting faces can be considered one of the initial steps in face recognition, which is essential for human interaction. We sought to investigate whether a face perception task reliably detects subtle perceptual disturbances between patients with bipolar disorder (BD) and healthy controls. Methods: In this multisite study, we examined differences between BD patients and matched healthy controls. Participants were instructed to detect the orientation (either left or right) of a face when it was presented as a face/non-face pair on a computer screen using Bayesian entropy estimation. Data analyses compared performance between the groups. Results: Overall, BD patients exhibited more perceptual disturbances compared with controls. BD patients who took olanzapine had better performance and faster reaction times (RTs) than patients who took lithium or were medication-naive. BD patients who took lithium had better performance and faster RTs than medication-naive patients. The medication-naive BD group exhibited greater disturbances than all other groups. Conclusion: These findings highlight the reliability of the face perception task used herein and may be important for public health initiatives and follow-up studies that seek to understand the diverse effects of other variables that can affect sensory processing in this population.

ABSTRACT Introduction: Eyelid xanthelasma is the most common form of cutaneous xanthoma, characterized by yellowish patches on the eyelid’s skin. Despite being a benign condition and not presenting with functional limitations, it is an important aesthetic complaint that impacts the patient’s social and emotional life. There are clinical therapeutic options, but the most widespread approach is the surgical approach with excision of the lesions, a simple procedure with few complications and lower local recurrence rates. This study aims to describe the surgical treatment of palpebral xanthelasma, to assess postoperative patient satisfaction and post-surgical recurrence rates. Methods: This is a retrospective study with a sample of 25 patients undergoing surgical treatment of eyelid xanthelasmas. Postoperative follow-up was performed at intervals of 7 days, 30 days, 90 days and 12 months with an interview, physical examination and application of a questionnaire that included the identification of local recurrences, postoperative complications and satisfaction with the aesthetic result. Results: Four patients evolved with local recurrence, and only two expressed dissatisfaction with the aesthetic result after the outcome. No patient who underwent surgical resection of lesions associated with autograft recurrence or dissatisfaction with the aesthetic result was observed. Conclusions: Surgical treatment as the first option in the therapeutic approach of eyelid xanthelasmas should be considered, given the aesthetic and psychological impact of such a condition. It is a simple technique, easy to apply and reproducible, effective, and safe, with relevant satisfaction rates and low recurrences.

RESUMO Introdução: O xantelasma palpebral é a forma mais comum de xantoma cutâneo, caracterizado por placas amareladas localizadas na pele das pálpebras. Apesar de ser uma condição benigna e não cursar com limitação funcional, é uma importante queixa estética que tem impacto na vida social e emocional do portador. Existem opções terapêuticas clínicas, mas a abordagem mais difundida é a cirúrgica com excisão das lesões, procedimento simples, com poucas complicações e menores taxas de recidivas locais. O objetivo deste estudo é descrever o tratamento cirúrgico do xantelasma palpebral, avaliar a satisfação dos pacientes no pós-operatório e as taxas de recidivas pós-cirúrgicas. Métodos: Trata-se de um estudo retrospectivo realizado com uma amostra de 25 pacientes submetidos a tratamento cirúrgico de xantelasmas palpebrais. O acompanhamento pós-operatório foi realizado em intervalos de 7 dias, 30 dias, 90 dias e 12 meses com entrevista, exame físico e aplicação de questionário que contemplaram identificação de recidivas locais, complicações pós-operatórias e satisfação com o resultado estético. Resultados: Quatro pacientes evoluíram com recidiva local e apenas dois pacientes manifestaram insatisfação com o resultado estético após o desfecho final. Em nenhum paciente submetido a ressecção cirúrgica das lesões associadas à autoenxertia foi observada recorrência ou insatisfação com o resultado estético. Conclusões: O tratamento cirúrgico como primeira opção na abordagem terapêutica dos xantelasmas palpebrais deve ser considerado, visto o impacto estético e psicológico de tal afecção. É uma técnica simples, de fácil aplicação e reprodutibilidade, eficaz, segura, com relevantes taxas de satisfação e baixa ocorrência de recidivas.

RESUMO As mudanças climáticas podem causar alterações drásticas nos ecossistemas lacustres especialmente em razão da elevação da temperatura e das alterações na precipitação, provocando, entre outros fatores, aumento no aporte de nutrientes e, consequentemente, eutrofização. Este trabalho apresenta a estimativa de projeções de vazão e carga de nutrientes (NO3−, PO4–3) afluentes à lagoa Mangueira — grande lagoa rasa subtropical localizada no extremo sul do Brasil. As projeções foram baseadas nos produtos do Quinto Relatório de Avaliação das Mudanças Climáticas (AR5), no Representative Concentration Pathway — RCP 2.6, RCP 4.5 e RCP 8.5. Em cada cenário, foram utilizados produtos de até 39 modelos climáticos globais para a estimativa das projeções das variáveis em dois períodos futuros de 30 anos, centrados em 2030 (próximo) e 2070 (longo). Os resultados mostram como situação mais provável o aumento das vazões, com maior concordância entre os produtos do AR5, quando comparados aos do Quarto Relatório de Avaliação das Mudanças Climáticas (AR4) estimados em trabalho anterior. Nas projeções de cargas de nutrientes também prevalece o padrão de aumento. Os nutrientes analisados apresentam elevação de carga média anual de 9,34% no futuro próximo e no RCP 2.6, enquanto no futuro longo e no RCP 8.5 esse valor se eleva para 22,48%. Medidas mitigadoras deverão ser previstas com o objetivo de reduzir a carga de nutrientes afluentes e manter o bom estado ecológico da lagoa.

ABSTRACT Climate change can cause drastic changes in lake ecosystems, especially due to the increase in temperature and changes in precipitation, promoting, among other factors, an increase in the nutrients input and, therefore, eutrophication. This paper estimated the projected flow and nutrients load (NO3−, PO4–3) at the Mangueira lake — a large subtropical shallow lake, located in southern Brazil. The projections were based on the AR5 products for RCP 2.6, RCP 4.5, and RCP 8.5 scenarios. In each scenario, data from as many as 39 global climate models were used to estimate the projected values of flow and nutrients in two 30-year time intervals centered at 2,030 (near future) and 2,070 (long future). Results show the increase in flow is more likely, with a greater agreement between AR5 products when compared to AR4 products estimated in previous work. The pattern of increase also prevails in the projections of nutrient loads. The nutrients analyzed show an average annual load increase of 9.34% in the near future and RCP 2.6 scenario, while in the long future and RCP 8.5 scenario, this value rises to 22.48%. Mitigation measures should be studied to reduce the nutrient inputs and to preserve a good ecological status of the lake.

Abstract Objective: To investigate the prevalence and factors associated with no intention to exclusively breastfeed for the first 6 months of life in a sample of women in the first 24 h postpartum during the hospital stay. Methods: Cross-sectional study with data from screening phase of a birth cohort. The proportion of mothers who did not intend to breastfeed exclusively for 6 months (primary outcome) derived from a negative response to the question “Would you be willing to try to breastfeed exclusively for the first 6 months?”, in an interview conducted by previously trained interviewers. Crude and adjusted prevalence ratios (PR) with 95% confidence intervals were obtained by Poisson regression with robust variance. Results: A total of 2964 postpartum women were interviewed. The overall prevalence of mothers who did not intend to breastfeed exclusively for 6 months was 17.8% (16.4–19.1%). After adjusting for maternal age and type of pregnancy (singleton or multiple), no intention to exclusively breastfeed was higher in mothers with a monthly household income < 3 minimum wages (PR, 1.64; 1.35–1.98) and in those who intended to smoke 4–7 days/week after delivery (PR, 1.42; 1.11–1.83). The presence of significant newborn morbidity (PR, 0.32; 0.19–0.54) and intention to breastfeed up to 12 months (PR, 0.46; 0.38–0.55) had a protective effect against not intending to breastfeed exclusively for 6 months. Conclusions: Approximately 1 in every 5 mothers did not intend to breastfeed exclusively for 6 months. Strategies aimed at promoting exclusive breastfeeding should focus attention on mothers from lower economic strata and smokers.
