Leishmania (Sauroleishmania) tarentolae versus pathogenic species: comparative evaluation of protease activity, glycoconjugates, resistance to complement and metabolome composition.

BACKGROUND: Leishmania tarentolae is a non-pathogenic species found in lizards representing an important model for Leishmania biology. However, several aspects of this Sauroleishmania remain unknown to explain its low level of virulence. OBJECTIVES: We reported several aspects of L. tarentolae biology including glycoconjugates, proteolytic activities and metabolome composition in comparison to pathogenic species (Leishmania amazonensis, Leishmania braziliensis, Leishmania infantum and Leishmania major). METHODS: Parasites were cultured for extraction and purification of lipophosphoglycan (LPG), immunofluorescence probing with anti-gp63 and resistance against complement. Parasite extracts were also tested for proteases activity and metabolome composition. FINDINGS: Leishmania tarentolae does not express LPG on its surface. It expresses gp63 at lower levels compared to pathogenic species and, is highly sensitive to complement-mediated lysis. This species also lacks intracellular/extracellular activities of proteolytic enzymes. It has metabolic differences with pathogenic species, exhibiting a lower abundance of metabolites including ABC transporters, biosynthesis of unsaturated fatty acids and steroids, TCA cycle, glycine/serine/threonine metabolism, glyoxylate/dicarboxylate metabolism and pentose-phosphate pathways. MAIN CONCLUSIONS: The non-pathogenic phenotype of L. tarentolae is associated with alterations in several biochemical and molecular features. This reinforces the need of comparative studies between pathogenic and non-pathogenic species to elucidate the molecular mechanisms of virulence during host-parasite interactions.

Increased interregional virus exchange and nucleotide diversity outline the expansion of chikungunya virus in Brazil.

The emergence and reemergence of mosquito-borne diseases in Brazil such as yellow fever, zika, chikungunya, and dengue have had serious impacts on public health. Concerns have been raised due to the rapid dissemination of the chikungunya virus across the country since its first detection in 2014 in Northeast Brazil. In this work, we carried out on-site training activities in genomic surveillance in partnership with the National Network of Public Health Laboratories that have led to the generation of 422 chikungunya virus genomes from 12 Brazilian states over the past two years (2021-2022), a period that has seen more than 312 thousand chikungunya fever cases reported in the country. These genomes increased the amount of available data and allowed a more comprehensive characterization of the dispersal dynamics of the chikungunya virus East-Central-South-African lineage in Brazil. Tree branching patterns revealed the emergence and expansion of two distinct subclades. Phylogeographic analysis indicated that the northeast region has been the leading hub of virus spread towards other regions. Increased frequency of C > T transitions among the new genomes suggested that host restriction factors from the immune system such as ADAR and AID/APOBEC deaminases might be driving the genetic diversity of the chikungunya virus in Brazil.

Increased interregional virus exchange and nucleotide diversity outline the expansion of the chikungunya virus ECSA lineage in Brazil.

The emergence and reemergence of mosquito-borne diseases in Brazil such as Yellow Fever, Zika, Chikungunya, and Dengue have had serious impacts on public health. Concerns have been raised due to the rapid dissemination of the chikungunya virus (CHIKV) across the country since its first detection in 2014 in Northeast Brazil. Faced with this scenario, on-site training activities in genomic surveillance carried out in partnership with the National Network of Public Health Laboratories have led to the generation of 422 CHIKV genomes from 12 Brazilian states over the past two years (2021-2022), a period that has seen more than 312 thousand chikungunya fever cases reported in the country. These new genomes increased the amount of available data and allowed a more comprehensive characterization of the dispersion dynamics of the CHIKV East-Central-South-African (ECSA) lineage in Brazil. Tree branching patterns revealed the emergence and expansion of two distinct subclades. Phylogeographic analysis indicated that the northeast region has been the leading hub of virus spread towards other regions. Increased frequency of C>T transitions among the new genomes suggested that host restriction factors from the immune system such as ADAR and AID/APOBEC deaminases might be driving CHIKV ECSA lineage genetic diversity in Brazil.

Does Parity Influence the Magnitude of the Stress Response of Nellore Cows at Weaning?

Most studies investigate the impact of stress at weaning on calves; however, little is known about the responses of cows, and whether they would differ according to parity. This study aims to investigate whether parity would influence the weaning stress response in beef cows. Thirty pregnant Nellore cows with their respective calves were randomly allocated to five paddocks and two females from each parity group were placed in the paddocks. There was an interaction (p < 0.05) between parity and evaluation days regarding cortisol, where on d + 7, the higher concentration was observed for multiparous cows. There was an interaction (p < 0.05) between parity and evaluation day for red blood cells (RBC), hematocrit (HCT), and hemoglobin (HB), whereby higher RBC counts on d + 4 were observed for multiparous cows. For HCT and HB, on all post-weaning collection days, higher values were observed for multiparous cows. The day of evaluation had an (p < 0.05) effect on all recorded behaviors, except for rumination (p > 0.05). Nellore cows, regardless of parity, underwent behavioral and physiological changes on abrupt weaning. Physiological parameters indicated that the magnitude of stress was greater in multiparous cows.

Experimental keratitis induced in rat by Acanthamoeba from distinct morphological groups/genotypes: a histological and immunohistochemical evaluation.

Species of the genus Acanthamoeba are free-living protozoans that occasionally act as parasites, causing a severe, progressive corneal infection termed Acanthamoeba keratitis (AK). The variable pathogenic potential among Acanthamoeba lineages has been shown by in vitro assays, but little is known about the behavior of different strains in animal models of AK. This work aimed to evaluate the infectivity of Acanthamoeba from distinct morphological groups and genotypes in a rat model of AK and apply an immunohistochemical technique for histological characterization of the lesions. Only a strain classified as group I/genotype T17, isolated from a soil source, caused ulcerated corneal lesions in two Wistar rats (n = 9) subjected to intrastromal inoculation. Two strains derived from AK human cases (group II/genotype T4 and group III/genotype T5) did not induce corneal lesions in the rats. A previous association of group II/genotype T4 trophozoites with lethally irradiated Escherichia coli did not influence the infectivity. A hyperimmune serum produced in Wistar rats was validated by an immunocytochemical technique using the three distinct strains and then applied for immunohistochemistry. The abundance of antigenic residues was observed in both corneas with keratitis, suggesting that the infectious process tended to resolve. Despite the low infection rate of the AK Wistar rat model, we produced an immunochemical tool with a potential diagnostic application. We also showed for the first time the ability of Acanthamoeba from T17 genotype to cause AK in experimental conditions.

"Aprendizagem Baseada em Memes": criatividade, afeto e cuidado em um componente curricular de Saúde Coletiva / "Meme-Based Learning": creativity, affection and care in a curricular component of Public Health

Resumo: Introdução: A pedagogia freiriana aponta a educação como uma prática social consoante a uma realidade em transformação e direcionada às demandas de seu público. Na educação médica, aplica-se tal concepção quando o ato pedagógico é um modelo de cuidado para os discentes. Nesse sentido, estratégias que promovem a expressão de sentimentos de forma livre, lúdica e criativa são práticas que promovem o cuidado e contribuem para uma formação humanista e reflexiva, como preconizado nas DCN para o curso de graduação em Medicina. O objetivo deste relato de experiência é compartilhar uma experiência bem-sucedida da utilização de memes em uma atividade de feedback do componente curricular de Saúde Coletiva de um curso de Medicina de uma universidade federal brasileira. Relato de experiência: No último encontro do semestre, os estudantes, reunidos em pequenas equipes, foram orientados a criar memes que refletissem suas principais percepções acerca do módulo, ou seja, que destacassem os momentos mais marcantes e os aprendizados compartilhados ao longo do semestre. Em seguida, a turma toda se reuniu por videochamada, e um representante de cada equipe fez o feedback apreciativo do semestre utilizando o meme criado, além de compartilhar o "momento a-há" elegido pelo grupo, ou seja, o mais marcante e transformador do módulo. Discussão: Percebe-se que a utilização de memes e outros recursos lúdicos na educação médica é importante e recomendada, pois, além de tornar o processo de aprendizagem mais ativo e efetivo, o que está de acordo com os princípios das DCN, é uma forma de cuidado em saúde com os discentes. Além disso, essa dinâmica permite uma maior interação entre os alunos e estimula o senso de pertencimento. Ademais, a realização de feedbacks na graduação de Medicina é fundamental para o processo de aprendizado e também para o aprimoramento de habilidades necessárias à prática profissional, e essa atividade se mostrou facilitada e efetiva quando feita por meio do uso de memes. Conclusão: A utilização de memes na sessão de feedback se mostrou benéfica, criativa e salutogênica, além de ser uma estratégia que preza o cuidado e a expressão de sentimentos dos alunos, e, por isso, deve ser encorajada.

Abstract: Introduction: Freirean pedagogy points to education as a social practice in line with a reality in transformation and directed to the demands of its public. In medical education, this concept is applied when the pedagogical act is a model of care for students. Accordingly, strategies that promote a free expression of feelings, in a playful and creative way are practices that promote care and contribute to a humanistic and reflective training, as recommended in the National Curriculum Guidelines (DCNs) for undergraduate medical training. The objective of this experience report is to share a successful experience of the use of memes in a feedback activity of the Public Health curricular component of a Medicine course at a Brazilian federal university. Experience report: In the last meeting of the semester, the students were grouped into small teams and instructed to create memes that reflect their main perceptions about the module, that is, to highlight the most remarkable moments and the lessons learned during the semester. Subsequently, the whole class assembled by video call and a representative of each team gave the appreciative feedback of the semester using the created meme, in addition to sharing the "a-ha moment" chosen by the group, that is, the most striking and transformative moment of the module. Discussion: One can note that the use of memes and other recreational resources in medical education is important and recommended, because, in addition to making the learning process more active and effective, which is in accordance with the principles of the NCGs, it is also a form of care in health with students. Conclusion: It is concluded that the use of memes in the feedback session proved to be beneficial, creative and salutogenic, as well as a strategy that values the care and expression of students' feelings and should be encouraged.

Restrição à atividade física na pandemia está associada com menor autoeficácia para dor na população com dor musculoesquelética: um estudo transversal / La restricción de la actividad física en la pandemia se asocia con menor autoeficacia para el dolor en la población con dolor musculoesquelético: un estudio transversal / Physical activity restriction in the pandemic is associated with lower pain self-efficacy in the population with musculoskeletal pain: cross-sectional study

RESUMO Durante a pandemia de COVID-19, observou-se um menor nível de prática de atividade física pela população, o que pode influenciar o nível de autoeficácia para dor na população com dor musculoesquelética. Neste contexto, o objetivo deste estudo foi analisar se existe associação entre o tempo de prática de atividade física e o nível de autoeficácia para dor na população com dor musculoesquelética durante a pandemia de COVID-19 no estado de São Paulo, controlada por variáveis biopsicossociais. Realizou-se um estudo através de um formulário online com questões sobre aspectos sociodemográficos, tempo semanal de prática de atividade física, níveis de estresse e ansiedade, intensidade de dor e autoeficácia para dor (PSEQ-10 - Pain Self-Efficacy Questionnaire). A análise estatística ocorreu por meio de dois modelos de regressão linear múltipla, com (modelo A) e sem (modelo B) o controle dos dados por fatores psicoemocionais (ansiedade e estresse) em 150 pessoas. Foi encontrada associação entre o tempo de prática de atividade física semanal e o nível de autoeficácia para dor no modelo A (p=0,0271, β=1,914) e no modelo B (p=0,0333, β=1,826). Intensidade de dor durante a pandemia, índice de massa corporal (IMC) e sexo, dentre as variáveis de controle, também foram associadas ao nível de autoeficácia para dor. Maior tempo de prática de atividade física foi associado a maior nível de autoeficácia para dor na população com dor musculoesquelética durante a pandemia de COVID-19. Intensidade de dor durante a pandemia, IMC e sexo também foram associados ao nível de autoeficácia para dor.

RESUMEN Durante la pandemia del COVID-19 se observó un menor nivel de actividad física en la población, lo que puede influir en el nivel de autoeficacia para el dolor en la población con dolor musculoesquelético.

La intensidad del dolor durante la pandemia, el índice de masa corporal (IMC) y el sexo, entre las variables de control, también se asociaron con el nivel de autoeficacia para el dolor. La práctica de actividad física durante más tiempo se asoció con un mayor nivel de autoeficacia para el dolor en la población con dolor musculoesquelético durante la pandemia del COVID-19. La intensidad del dolor durante la pandemia, el IMC y el género también se asociaron con el nivel de autoeficacia para el dolor.

ABSTRACT During the COVID-19 pandemic, a lower level of physical activity was observed in the population, which may influence the level of pain self-efficacy in the population with musculoskeletal pain. In this context, this study sought to analyze whether there is an association between the time of physical activity practice and the level of pain self-efficacy in the population with pain during the COVID-19 pandemic in the state of São Paulo, controlled by biopsychosocial variables. This study was conducted via an online form with questions about sociodemographic aspects, weekly physical activity practice, stress and anxiety levels, pain intensity and pain self-efficacy (Pain Self-Efficacy Questionnaire - PSEQ-10). The analysis was determined by two models of multiple linear regression, with (Model A) and without (Model B) the control of data by psycho-emotional factors (anxiety and stress) in 150 subjects. An association was found between weekly physical activity practice time and pain self-efficacy level, Model A (p=0.0271, β=1.914) and Model B (p=0.0333, β=1.826). Pain intensity during the pandemic, body mass index (BMI) and sex, among the control variables, also were associated with the pain self-efficacy level. A higher time of physical activity practice was associated with a higher pain self-efficacy level in the population with musculoskeletal pain during the COVID-19 pandemic. Pain intensity during the pandemic, BMI and sex also were associated with pain self-efficacy level.

Pain self-efficacy and physical activity during COVID-19-related social distancing: cross-sectional study / Autoeficácia para dor e atividade física durante o distanciamento social relacionado à COVID-19: estudo transversal

ABSTRACT BACKGROUND AND OBJECTIVES: The COVID-19 pandemic has impacted the practice of physical activity in the population with musculoskeletal pain, and one of the ways to increase the performance of physical activity is to stimulate pain self-efficacy. However, to date, no study that brought the association between self-efficacy and physical activity in this population has been observed in the literature. The aim of this study was to analyze the association of the level of pain self-efficacy and physical activity weekly time in the population with pain during social distancing related to the COVID-19 pandemic in the states of Ceará and São Paulo. METHODS: This study is characterized as a cross-sectional study with a quantitative approach. Data collection was performed using an electronic form. To identify the association between pain self-efficacy (Pain Self-Efficacy Questionnaire) and physical activity weekly time (dependent variable) in the population with pain, a multiple linear regression was performed. RESULTS: Self-efficacy showed a direct association (ß = 0.015; p = 0.0016) with the time of physical activity practiced during the pandemic. Other variables were associated with longer time of physical activity, such as lower pain intensity during the pandemic (ß = -0.064; p = 0.0223), lower body mass index (ß = -0.036; p = 0.0004), the male gender (ß = -0.441; p<0.0001) and absence of reported comorbidities (ß = -0.297; p = 0.0116). The history of positive diagnosis for COVID-19 was not associated with the physical activity duration (p = 0.5347) in an alternative model. CONCLUSION: A direct association between pain self-efficacy and time of physical activity in the population with musculoskeletal pain during COVID-19-related social distancing was identified.

RESUMO JUSTIFICATIVA E OBJETIVOS: A pandemia de COVID-19 impactou a prática de atividade física da população com dor musculoesquelética (DME), e um dos modos de ampliar a realização da atividade física é estimulando a autoeficácia para dor. Entretanto, até o momento, não se observou na literatura qualquer estudo que trouxesse a relação entre autoeficácia e atividade física nessa população. O objetivo deste estudo foi analisar a associação do nível de autoeficácia e do tempo semanal de prática de atividade física na população com dor durante o distanciamento social relacionado à pandemia de COVID-19 nos estados do Ceará e São Paulo. MÉTODOS: Este estudo se caracteriza como um estudo transversal com abordagem quantitativa. A coleta de dados foi realizada a partir de um formulário eletrônico. Para identificação da associação entre autoeficácia (Pain Self-Efficacy Questionnaire) e tempo semanal de prática de atividade física (variável dependente) na população com dor, foi realizada uma regressão linear múltipla. RESULTADOS: A autoeficácia apresentou relação direta (ß = 0,015; p = 0,0016) com tempo de atividade física praticada durante a pandemia. Outras variáveis apresentaram associação com maior tempo de prática de atividade física, como menor intensidade de dor durante a pandemia (ß = -0,064; p = 0,0223), menor índice de massa corporal (ß = -0,036; p=0,0004), ser do sexo masculino (ß = -0,441; p<0,0001) e relatar ausência de comorbidades (ß = -0,297; p = 0,0116). O histórico de diagnóstico positivo para COVID-19 não apresentou associação com tempo de atividade física (p = 0,5347). CONCLUSÃO: Identificou-se associação direta entre autoeficácia para dor e tempo de prática de atividade física na população com dor musculoesquelética durante o distanciamento social relacionado à COVID-19.

Análise epidemiológica dos casos de Aids no Sudeste brasileiro de 2010 a 2019 / Epidemiological analysis of Aids cases in Southeastern Brazil from 2010 to 2019 / Análisis epidemiológico de casos de Sida en el sudeste de Brasil de 2010 a 2019

Resumo Introdução: A epidemia de HIV e Aids representa um dos maiores problemas de saúde pública atualmente. No Brasil, estima-se que apenas 83 % das pessoas vivendo com HIV conhecem seu diagnóstico e somente 46 % possuem carga viral indetectável. Isso evidencia a necessidade de estudos voltados à compreensão do HIV e da Aids no Brasil, para a melhora das políticas públicas. Assim, o objetivo deste estudo é realizar um levantamento de dados sobre o perfil epidemiológico de pacientes portadores de Aids no Sudeste brasileiro. Métodos: Trata-se de um estudo epidemiológico descritivo, de caráter quantitativo. Os dados foram obtidos no SINAN. A análise restringiu-se ao período de janeiro de 2010 a junho de 2019. Resultados: No período analisado, o ano de 2017 apresentou a maior prevalência da doença (11,97 %). Além disso, observa-se uma tendência de crescimento no número de casos entre 2010 e 2014 e uma tendência decrescente nos últimos anos. O Rio de Janeiro foi o estado com maior número de novos casos (21,90 %) da Região Sudeste. Observou-se que os grupos com maior incidência de casos foram: sexo masculino (71,1 %), jovens e adultos (79,37 %), cor branca (46,67 %), ensino médio completo (19,71 %) e heterossexuais (46,94 %). Contudo, foi observado um aumento relativo da incidência entre homens homossexuais e entre os pardos. Além disso, a principal forma de transmissão foi via sexual (78,09 %). Conclusão: O estudo concluiu que são necessárias mais pesquisas acerca do tema, para acompanhar a epidemiologia da Aids e orientar medidas governamentais eficientes.

Abstract Introduction: The HIV and Aids epidemic represents one of the biggest public health problems today. In Brazil, it is estimated that only 83 % of people living with HIV know their diagnosis and only 46 % have an undetectable viral load. This highlights the need for studies aimed at understanding HIV and Aids in Brazil, to improve public policies. Thus, this study aims to conduct a survey of data on the epidemiological profile of Aids patients in Southeast Brazil. Methods: It is a descriptive, quantitative epidemiological study. The data was extracted from SINAN. The analysis was restricted to the period from January 2010 to June 2019. Results: In the analyzed period, 2017 had the highest prevalence of the disease (11,97 %). In addition, there was an increase in the number of cases between 2010 and 2014 and a drop over the last few years. Rio de Janeiro was the state with the highest number of new cases (21,90 %) in the Southeast Region. Results: The groups with the highest incidence of cases were: man (71,1 %), young and adults (79,37 %), white (46,67 %), high school graduates (19,71 %) and heterosexuals (46,94 %). However, a relative increase in incidence was observed among homosexual men and among browns. Also, sexual transmission was the most prevalent (78,09 %). Conclusion: The study concluded that more research on the topic is needed, to monitor the epidemiology of Aids and to guide efficient government measures.

Use of Focus Group as Selection Method of Descriptors for Check-All-That-Apply (CATA) for Sensory Characteristics of Hot Dogs.

Check-all-that-apply (CATA) is a methodology for sensory product characterization that can be used by consumers. These characteristics, on the other hand, are determined by a trained panel, and consumers are not asked how they perceive these attributes; as a result, some of the characteristics raised by the trained panel may not be relevant to consumers. In this study, the CATA test was applied to characterize three types of hot dogs, those with or without irradiation and salt reduction, and the focus group (FG) technique was employed to determine the CATA descriptors. Each participant in the FG provided five words (attributes) that, in their opinion, best defined each sample. Then, to understand the meaning and to assemble each of the different terms, a discussion of the defined attributes was conducted. The list of CATA descriptors was compiled using the most often cited attributes. The findings indicate that the major difference in hot dogs was between the formulations with and without sodium reduction. The consumers only noticed minor effects resulting from the irradiation process. The use of focus group as the method to select the CATA descriptors related to hot dogs was proven to be valid since the words that were listed for these samples were attributes that typically characterize hot dog sausages.

Lesão transfixante de carótida por espinha de peixe - relato de caso / Carotid artery perforation by fish bone - a case report

Abstract Accidental fish bone ingestion is a common complaint at emergency departments. The majority of cases have a benign course. However, serious complications such as esophagus perforation, cervical vessel injury and cervical abscess can occur in 7.4% of cases. Mortality rates can be as high as 50% when mediastinitis occurs. We report a case of an esophageal perforation caused by a fish bone with a lesion to the right common carotid artery after 20 days of evolution. Surgical exploration occurred with corrections of the lesion in the right common carotid and esophagus. Early identification of this kind of injury is paramount to prevent potentially fatal complications.

Evaluation of Non-linear Models to Predict Potential Milk Yield of Beef Cows According to Parity Order Under Grazing.

This study aimed to evaluate the effect of parity order on milk yield (MY) and composition over time of grazing beef cows and to evaluate non-linear models to describe the lactation curve. Thirty-six pregnant Nellore cows (12 nulliparous, 2 years; 12 primiparous, 3 years; and 12 multiparous, 4-6 years) were included in the study. With calving day assigned as day 0, milking was performed using a milking machine to estimate MY on days 7, 14, 21, 42, 63, 91, 119, 154, and 203. Dummy variable analyses were applied to estimate its effects on MY, composition (kg and percentage), afternoon/morning, and afternoon/total proportions. Since multiparous cows had higher MY than nulliparous and primiparous cows, two different groups were used for lactation curve analysis: Mult (multiparous) and Null/Prim (nulliparous and primiparous). The MY estimated by the last edition of BR-Corte (Nutrient Requirements of Zebu and Crossbred Cattle) equation was compared with the observed values from this study. Five nonlinear models proposed by Wood (WD), Jenkins & Ferrell (JF), Wilmink (WK), Henriques (HR) and Cobby & Le Du (CL) were evaluated. Models were validated using an independent dataset of multiparous and primiparous cows. The estimates for parameters a, b, and c of the CL equation were compared between groups, and the BR-Corte equation used the model identity methodology. Nulliparous and primiparous cows displayed similar MY (P > 0.05); however, multiparous cows had an average MY that is 0.70 kg/day greater than that of nulliparous and primiparous cows (P < 0.05). Milk protein and total solids were higher for multiparous cows (P < 0.05). Effect of days in milking was found for milk fat, protein, and total solids (P < 0.05). The yield of all milk components was higher for multiparous cows than for nulliparous and primiparous cows. The afternoon/morning and afternoon/total proportions of milk production were not affected by parities and days in milking (P > 0.05), with an average of 0.76 and 0.42, respectively. The BR-Corte equation did not correctly estimate the MY (P < 0.05). The equations of WD, WK, and CL had the best estimate of MY for both Mult and Null/Prim datasets. The equations had a very similar Akaike's information criterion with correction and mean square error of prediction.

Effects of parity order on performance, metabolic, and hormonal parameters of grazing beef cows during pre-calving and lactation periods.

BACKGROUND: Metabolic profile evaluation is a tool widely used in ruminant nutrition as metabolic cues that relate nutrition to physiology. Metabolic and hormonal traits change during pre-partum and lactation according to parity in dairy cows, but studies of beef cows under grazing are scarce. The present study aimed to evaluate how metabolic and hormonal traits change over time, their relationship to performance, and determine if these factors differ according to the parity order of grazing beef cows. Thirty-six pregnant Nellore cows (12 nulliparous, 12 primiparous, and 12 multiparous) were used. The study started at 60 d prepartum until 203 d of lactation. RESULTS: The initial body weight (BW) and final BW were higher for multiparous cows (P > 0.05). An interaction occurred between parity and day (P < .0001) for body condition score. Nulliparous and primiparous body condition score were reduced from - 60 prepartum to 30 postpartum, then stabilized 60 postpartum (P < 0.05), while multiparous maintained body condition score from - 60 days until 60 days postpartum (P > 0.05). Calf BW, final BW, and average daily gain did not differ between parities (P > 0.05). Effect of day (P < 0.05) was detected for non-esterified fatty acids, triglycerides, total cholesterol, LDL, VLDL, progesterone, and insulin. An interaction was observed between parity and days for glucose, HDL, ß-hydroxybutyrate, creatinine and IGF-1 (P < 0.05). Parity affected serum urea nitrogen, total proteins, albumin, and globulins (P < 0.05). Parity and day relative to calving did not impact total T3 and T4 (P > 0.05). CONCLUSIONS: Hormonal and metabolic profile is strongly influenced by the stage of lactation. Time effects (pre-partum and lactation period) were more pronounced in nulliparous since they displayed more unbalanced metabolic and hormonal traits and lowered BCS pre- and postpartum.

Constatou-se que as expectativas acadêmicas, a satisfação com a experiência acadêmica e as HS impactaram positivamente nas vivências acadêmicas. Houve impacto positivo dos fatores Curso da ESEA e Autoconhecimento da EMEP e impacto negativo do fator Determinação. O presente estudo contribuiu principalmente mostrando a importância do comportamento das variáveis do modelo testado. Por ser a adaptação acadêmica um construto multideterminado, os resultados alcançados podem apontar para ações de intervenções no acolhimento de universitários ingressantes, considerando aspectos como autoconhecimento, determinação, expectativas acadêmicas, conhecimento da realidade e satisfação com a graduação.

The aim of the study was to verify if the variables academic expectations, satisfaction with academic experience, maturity for professional choice and social skills explain the variable academic adaptation criterion. Participated 212 university students in the 1st year of the Psychology course. The following instruments were used: Academic Experience Questionnaire (AEQ), Academic Expectations Scale for Students in Higher Education (AESSHE), Academic Experience Satisfaction Scale (AESS), Social Skills Inventory (SSI) and Scale of Maturity for the Professional Election (SMPE). Multiple Linear Regression was used for data analysis. It was found that the academic expectations, satisfaction with the academic experience and the social skill impact positively on the academic experiences. There was a positive impact on the Factors of the AESS and Self-knowledge of the SMPE and negative impact of the factor Determination. The present study contributed mainly by showing the importance of the behavior of the variables of the tested model. Once academic adaptation is a multidetermined construct, the results achieved can point to interventions in the reception of university students, considering aspects such as self-knowledge, determination, academic expectations, knowledge of reality and satisfaction with undergraduate education.

Analysis of vaccine loss due to temperature change.

OBJECTIVES: to analyze vaccine losses in a Health Region in the Northwest of São Paulo. METHODS: retrospective cross-sectional study with secondary data obtained from Temperature Change Notification Forms used by the Epidemiological Surveillance Group XXIX of São José do Rio Preto between 2010 and 2017. Descriptive and inferential analysis were performed using multiple linear regression and significance level of 95%. RESULTS: in total, 341 notifications of temperature changes were analyzed, of which 70.1% were caused by structural reasons, 57.8% in industrial refrigerators and 91.2% in primary care services. Of the doses that suffered a change in temperature, 41.4% were lost and 58.6% were administered to the population. The highest percentage of lost doses compared to those applied occurred in smaller municipalities, although they reported less. CONCLUSIONS: nursing workers who work in vaccination rooms should make efforts to prevent temperature changes and avoid losses and higher public expenses.

Factors influencing endothelial cell density of corneas for transplantation.

To evaluate factors affecting corneal endothelial cell density (ECD) under enucleation and preservation time studies at Eye Bank of the Federal District of Brazil. We conducted a case-control study collecting data from 1128 corneas where death-to-enucleation time and enucleation-to-preservation time were within 24 h. Low cell count were those corneas with an ECD less than 2000 cells/mm2 and high cell count was defined as those with ECD greater than 2000 cells/mm2. We calculated the independent risk factors related to: cause of death, donor age, death-to-enucleation time, enucleation-to-preservation time and primary graft failure. Correlation analysis was used to assess which parameters influence ECD: death-to-enucleation time, enucleation-to-preservation time, average cell area (AVE), coefficient of variation and percentage of hexagonal cells. Of the total number of corneas, 1004 had ECD data and were selected for the study. 87.4% (n = 877) had high cell counts with 2699 ± 412 cells/mm2. The mean donor age was 38.8 ± 16 years. The most common causes of death were external causes (48.6%, n = 488). Longer times from death-to-enucleation, up to 24 h were not associated with a decrease in ECD (OR 0.58; P = 0.44) or risk of graft survival (P = 0.74). Enucleation-to-preservation intervals greater than 12 h showed increased risk of graft survival (P = 0.04). AVE was the main parameter for ECD (R2 = 0.96, P < 0.001). The overall graft survival rate was 98.2% (n = 761). Donors with 40 years of age and above did not present a higher risk of graft survival (P = 0.09). We suggest that the maximum time from death-to-enucleation should be 24 h, assuming the body has been refrigerated after 6 h; and from enucleation-to-preservation time of 12 h, followed by proper processing and cornea morphology examination.

Sentimento de Pertencimento e Desenvolvimento da Moralidade na Escola / The Sense of Belonging and the Development of Morality in Schools

Resumo O presente artigo discute a importância de a escola oferecer um "espaço para o brincar" para crianças que enfrentam conflitos morais sérios. Mediante a apresentação de vinhetas, analisa alguns diálogos travados durante o brincar em uma sala de aula, entre uma criança e uma bolsista participante do Programa Institucional de Bolsas de Iniciação à Docência - PIBID/Capes. À luz de conceitos da psicanálise, o estudo demonstra como o brincar promove um ambiente suficientemente bom que, com a ajuda de um adulto significativo, é vital para que aspectos morais sejam abordados sem moralismos ou racionalizações e para que o sentimento de pertencimento permita à criança usufruir mais profundamente do ambiente escolar.

Abstract This article discusses the importance of school offering a "space to play" for children who face serious moral conflicts. Through the presentation of vignettes, it analyzes some dialogues exchanges, during classroom playtime, between a child and a grant-holder participating in the PIBID/Capes Institutional Teacher Training Grant Program. In the light of psychoanalytical concepts, the study demonstrates how play promotes a good-enough environment that, with the help of a significant adult, is vital for moral aspects to be dealt without moralism or rationalizations, and for the feeling of belonging to allow a child to have a deeper enjoyment of the school environment.
