ABSTRACT OBJECTIVE To examine the perceptions of adolescent students from a public school, of both sexes, living in a peripheral region of the city of São Paulo, Brazil, in relation to the covid-19 pandemic, with a special focus on their experiences regarding education and sociability. METHODS This study is part of the Global Early Adolescent Study. Seven face-to-face focus groups were conducted with adolescents between 13 and 16 years old (19 girls and 15 boys) in 2021. RESULTS The experience of remote teaching was frustrating for the adolescents, without the daily and personalized monitoring of the teacher(s). In addition to the difficult or impossible access to devices and the lack of support from schools, there is also the domestic environment, which made the schooling process more difficult, especially for girls, who were forced to take on more household and family care tasks. The closed school blocked an important space for socialization and forced family interaction, generating conflicts and stress in the home environment. The abrupt rupture brought feelings of fear, uncertainty, anguish and loneliness. The iterative evocation of the words “stuck”, “alone” and “loneliness” and the phrase “there was no one to talk to” shows how most of the adolescents experienced the period of distancing. The pandemic aggravated the objective and subjective conditions of preexisting feelings, such as “not knowing the future” and the prospects of a life project. CONCLUSION It has been documented how pandemic control measures implemented in a fragmented way and without support for the most impoverished families have negative effects on other spheres of life, in particular for poor young people. The school is a privileged territory to propose/construct actions that help adolescents to deal with problems aggravated in/by the pandemic.

Abstract Background Cardiovascular risk factors are prognostic factors in coronavirus disease 2019 (COVID-19) and have been scarcely studied in Brazil. Objective The aim of this study was to assess the impact of cardiovascular risk factors on the outcomes of patients admitted for COVID-19. Methods From July 2020 to February 2021, 200 patients from two public hospitals were enrolled. Patients were included if they had typical symptoms or signs of COVID-19, a positive real-time polymerase chain reaction test (RT-PCR) for COVID-19, and an age above 18 years. This is a prospective, observational, and longitudinal study. Data were collected within 24 h of admission. The primary endpoint was a combination of hospital lethality, mechanical ventilation, hemodialysis, or length of hospital stay >28 days. Continuous variables were compared with the Student’s t-test for independent samples or the Mann-Whitney test. For comparisons of proportions, the χ 2 test was applied. ROC curves and survival curves were constructed. Multivariate logistic regression was performed to identify independent predictors of events. The level of significance was 0.05. Results There were 98 (49%) events during the hospital course, and 72 (36%) died in the hospital. Patients with a primary endpoint were older and more likely to have a history of hypertension, diabetes, chronic obstructive pulmonary disease (COPD), and chronic kidney disease (CKD). Vital signs at admission associated with events were diastolic blood pressure, respiratory rate, and oxygen saturation in ambient air (O 2 Sat). Serum creatinine >1.37 mg/dL at admission had a sensitivity of 51.6 and a specificity of 82% to predict the primary endpoint, with an area under the curve (AUC) of 0.68. In multivariate analysis, age, diabetes, CKD, and COPD were independent predictors of the primary endpoint. Age and CKD were independent predictors of in-hospital lethality. Conclusion Cardiovascular risk factors, such as diabetes and CKD, were related to a worse prognosis in patients hospitalized with COVID-19 in this sample from two public hospitals in the state of Rio de Janeiro.

Abstract Disarticulated shells of three bivalve mollusk species (Anomalocardia brasiliana, Codakia orbicularis, and Divaricella quadrisulcata) were experimentally tested in laboratory flumes to determine the threshold of motion and final orientation of the valves. A total of 150 current flow experiments were conducted on single shells resting on a fixed sand bed. This study demonstrated that shells in the convex-up position are more resistant to flow when the umbo is pointing downstream rather than upstream. Moreover, species with higher frontal areas were more likely to be entrained at lower flow velocities. Results of dimensionless shear stress exhibited values far below the threshold of grains movement for beds of uniform roughness (Shields curve). It was observed that circular shells in convex-up positions were mostly orientated with the umbo pointing downstream. Conversely, elliptical shells in convex-up position tended to align their longer axis parallel to the flow with the posterior side of the valve pointing downstream. These results are not only directly applicable in interpretations of incipient shell motions and in paleocurrent analyses from field and sample data, but also support construction of accurate geological models.

Abstract: The thermoinhibition of lettuce seed germination causes important losses for producers, who do not have thermotolerant commercial cultivars. One of the obstacles has been the scarcity of optimizing techniques capable of efficiently discriminating thermotolerant and thermosensitive cultivars. The aim of this work was to evaluate the use of neural networks to discriminate different levels of thermoinhibition in lettuce seeds. Seeds of 18 cultivars were evaluated for thermoinhibition considering the characteristics of the first and last germination count and germination speed index, in seeds subjected to temperatures of 20, 25, 30 and 35 °C. The remaining seeds, which did not germinate, were subjected to the tetrazolium test. Analyses were performed immediately after seed harvesting and repeated after six months of storage. Discriminant analysis was performed and the Kohonen’s Self-Organizing Map (SOM) was created using Artificial Neural Networks (ANNs). Neural networks discriminate lettuce cultivars and organizes them in terms of seed thermoinhibition tolerance through Kohonen’s Self-Organizing Map. Discriminant analysis consistently identifies the Everglades and Luiza genotypes as tolerant to thermoinhibition.

Resumo: A termoinibição causa perdas importantes para os produtores, os quais não dispõem de cultivares comerciais com sementes termotolerantes. Há escassez de técnicas otimizadoras capazes de discriminar cultivares termotolerantes e termosensíveis com eficiência. Objetivou-se avaliar o uso de redes neurais para discriminar diferentes níveis de termoinibição em sementes de alface. Foram avaliadas sementes de 18 cultivares quanto à termoinibição considerando às características de primeira e última contagem de germinação e índice de velocidade de germinação, em sementes submetidas às temperaturas de 20, 25, 30 e 35 °C. As sementes remanescentes, que não germinaram, foram submetidas ao teste de tetrazólio. As análises foram realizadas imediatamente após a colheita das sementes e repetidas após seis meses de armazenamento. Uma análise discriminante e o Mapa Auto-Organizável de Kohonen (SOM) por Redes Neurais Artificiais (RNA’s) foram realizados. As redes neurais discriminam as cultivares de alface e as organiza quanto a tolerância a termoinibição das sementes por meio do Mapa Auto-Organizável de Kohonen. A análise discriminante indentifica de maneira coerente o genótipo Everglades e Luiza como tolerantes a termoinibição.

ABSTRACT Objectives: to evaluate the outcomes of Interval Copper Intrauterine Device (IUD) insertion performed by certified midwives and obstetric nurse practitioners at a Peri-Hospital Birth Center. Methods: a cross-sectional study was conducted involving 75 women who underwent IUD insertion between January 2018 and February 2020. Data collection was carried out using medical records and telephone interviews. Results: no instances of uterine perforation were observed. Expulsion rates of the devices were 1.3% within 30 to 45 days of use and 5.3% within the first year of use. The follow-up removal rate was 4.0%. The average pain score reported was 4.2 (SD = 3.3). Among those who continued using the device, 93.1% expressed satisfaction. Conclusions: the findings demonstrate that IUD insertion by certified midwives and obstetric nurse practitioners is a safe procedure, yielding outcomes comparable to those reported in the existing literature.

ABSTRACT Objective: To assess the sociodemographic aspects associated with reproductive autonomy among urban women, with special regard to the relationship with the use of contraceptive methods. Method: Cross-sectional study with 1252 women, conducted between April and June 2021, using the Brazilian version of the Reproductive Autonomy Scale. Data were analyzed using multiple linear regression. Results: Mean scores for the subscales were 2.5 (SD=0.3) (Decision-making), 3.8 (SD=0.3) (Absence of Coercion) and 3.6 (SD=0.4) (Communication). Compared to women who reported no use of contraceptive methods, women using barrier or behavioral methods and those using LARC had higher level of reproductive autonomy on all dimensions of the Scale (p<0.001). Other aspects associated with reproductive autonomy were education, race/ethnicity, religion, socioeconomic status and cohabitation living with a partner, depending on each subscale. Conclusion: The type of contraceptive method used was statistically associated with reproductive autonomy in all subscales.

RESUMEN Objetivo: Verificar los aspectos sociodemográficos asociados a la autonomía reproductiva entre mujeres urbanas, especialmente en relación al uso de métodos anticonceptivos. Método: Estudio transversal realizado con 1252 mujeres, entre abril y junio de 2021, utilizando la versión brasileña de la Escala de Autonomía Reproductiva. Los datos se analizaron mediante regresión lineal múltiple. Resultados: Las puntuaciones medias de las subescalas fueron 2,5 (DE=0,3) (Toma de decisiones), 3,8 (DE=0,3) (Ausencia de coerción) y 3,6 (DE=0,4) (Comunicación). En comparación con las mujeres que informaron no usar métodos anticonceptivos, las mujeres que usaron métodos de barrera o conductuales y las que usaron LARC mostraron un mayor nivel de autonomía reproductiva en todas las dimensiones de la Escala (p<0,001). Otros aspectos asociados a la autonomía reproductiva fueron la educación, la raza/color, la religión, el grupo socioeconómico y la convivencia, según cada subescala. Conclusión: El tipo de método anticonceptivo utilizado se asoció estadísticamente con la autonomía reproductiva en todas las subescalas.

RESUMO Objetivo: Verificar os aspectos sociodemográficos associados à autonomia reprodutiva entre mulheres urbanas, em especial na relação com o uso de métodos contraceptivos. Método: Estudo transversal realizado com 1252 mulheres, entre abril e junho de 2021, utilizando a versão brasileira da Escala de Autonomia Reprodutiva. Os dados foram analisados por meio de regressão linear múltipla. Resultados: Os escores médios das subesacalas foram 2,5 (dp=0,3) (Tomada de decisão), 3,8 (dp=0,3) (Ausência de Coerção) e 3,6 (dp=0,4) (Comunicação). Comparadas às mulheres que relataram não usar métodos contraceptivos, mulheres que usavam métodos de barreira ou comportamentais e as que usavam LARC mostraram maior nível de autonomia reprodutiva em todas as dimensões da Escala (p<0,001). Outros aspectos associados à autonomia reprodutiva foram a escolaridade, raça/cor, religião, grupo socioeconômico e morar com o parceiro,a depender de cada subescala. Conclusão: O tipo de método contraceptivo utilizado foi estatisticamente associado à autonomia reprodutiva em todas as subescalas.

RESUMO A mastopexia é a cirurgia plástica responsável pela correção da ptose mamária, problema caracterizado pela discrepância entre o volume da mama e sua camada cutânea. As complicações mais relatadas no pós-operatório imediato são deiscência de suturas, seroma, edema e infecção, enquanto outras, como a galactorreia, são consideradas raras. O caso em questão consiste em uma paciente de 52 anos, que realizou a mastopexia bilateral com inclusão de prótese e desenvolveu após 30 dias do procedimento galactorreia com hiperprolactinemia. O diagnóstico foi suspeitado devido ao aumento de volume, associado a dor ou desconforto mamário no pós-operatório, seguido de saída secreção leitosa. A galactocele pós-mastopexia com prótese pode ou não estar associada à hiperprolactinemia, porém pouco se sabe sobre a real fisiopatologia do desenvolvimento desse quadro. O tratamento foi feito com cabergolina 0,5mg em duas doses, com melhora do quadro.

ABSTRACT Mastopexy is the plastic surgery responsible for correcting breast ptosis, a problem characterized by a discrepancy between the volume of the breast and its skin layer. The complications most commonly reported in the immediate postoperative period are suture dehiscence, seroma, edema and infection, while others such as galactorrhea are considered rare. The case in question consists of a 52-year-old patient who underwent bilateral mastopexy with prosthesis inclusion and developed galactorrhea with hyperprolactinemia 30 days after the procedure. The diagnosis was suspected of increased volume, associated with postoperative breast pain or discomfort, followed by milky discharge. Galactocele after mastopexy with a prosthesis may or may not be associated with hyperprolactinemia, but little is known about the real pathophysiology of the development of this condition. Treatment was done with cabergoline 0.5mg in two doses, improving the condition.

ABSTRACT BACKGROUND: Multiple opinion-based communications have highlighted the actions of the Brazilian government during the pandemic. Nevertheless, none have appraised public data to identify factors associated with worsening of the healthcare system. OBJECTIVE: To analyze and collate data from public health and treasury information systems in order to understand the escalating process of weakening of Brazilian healthcare and welfare since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. DESIGN AND SETTING: Secondary data study conducted using multiple public databases administered by the Brazilian federal government. METHODS: We processed information from multiple national databases and appraised health and economic-related data. RESULTS: Based on our analyses, there were substantial reductions in inpatient hospital admissions and in the numbers of patients seeking primary care services, along with a decrease in immunization coverage. Moreover, we observed a considerable decline in government transfers to hospital services (reduction of 82.0%) and a diminution of public outlays in several healthcare-related subfunctions (“hospital and outpatient care”, “primary care”, “prophylactic and therapeutic support” and “epidemiological surveillance”). We observed an increase in the overall mortality rate over the period analyzed, especially regarding all group-based diseases. Notably, there were remarkable differences among geographic, racial, gender and other parameters, thus revealing the impact of vulnerabilities on COVID-19 outcomes. CONCLUSION: This assessment of documentation of public expenditure and the shrinkage of investment in sensitive areas of the healthcare system in Brazil emphasized areas that still require collective attention in order to guarantee national welfare.

RESUMO Objetivos: apreender o cuidado à dimensão espiritualprestado porcuidadoresem instituição de longa permanência para idosos. Métodos: pesquisa qualitativa, realizada em um centro geriátrico de hospital filantrópico na cidade de Salvador, Bahia. Participaram 18 cuidadores formais, por meio da entrevista semiestruturada, entre janeiro e fevereiro de 2019. Os dados foram analisados à luz da Teoria do Cuidado Transpessoal de Jean Watson. Resultados: o cuidador formal dialoga sobre a dimensão espiritual a partir das crenças religiosas do idoso, incentiva as práticas religiosas e exerce o cuidado espiritual de acordo com as demandas físicas, emocionais e espirituais da pessoa idosa. Considerações Finais: os cuidadores formais compreendem que as vivências religiosas ou espirituais da pessoa idosa devem ser incluídas na sua rotina de trabalho. O cuidado à dimensão espiritual ocorre pelo estímulo a fé em Deus, incentivo às práticas religiosas e acolhimento de suas crenças frente às demandas físicas, emocionais e espirituais.

ABSTRACT Objectives: to understand care for the spiritual dimension provided by caregivers in a Nursing Home. Methods: this is a qualitative research, carried out in a geriatric center of a philanthropic hospital in the city of Salvador, Bahia. Eighteen formal caregivers participated, through a semi-structured interview, between January and February 2019. The data were analyzed in the light of Jean Watson’s Theory of Transpersonal Caring. Results: formal caregivers discuss the spiritual dimension based on older adults’ religious beliefs, encourage religious practices and exercise spiritual care according to older adults’ physical, emotional and spiritual demands. Final Considerations: formal caregivers understand that older adults’ religious or spiritual experiences should be included in their work routine. Care for the spiritual dimension occurs by stimulating faith in God, encouraging religious practices and embracing their beliefs in the face of physical, emotional and spiritual demands.

Abstract The Brazilian Amazon forests are interspersed by savanna ecosystems distributed in the states of Amapá, Amazonas, Pará, Rondônia and Roraima, presenting different distribution patterns. The objective of this work was to evaluate the richness, composition and floristic similarity of the bryophyte flora from five disjunct savanna areas in the eastern Amazon and compare the richness with those of other savannas in Brazil. The collections were carried out from 2017 to 2018 in five localities of the eastern Amazon. Twenty-two species of mosses and 22 species of liverworts were registered. The composition was expected for savanna ecosystems with 27 species of generalists and 16 sun specialists. There was a striking floristic difference between the areas, and the clusters showed that the eastern Amazon savannas are formed by different compositions related to their area. This study made it possible to discover one new record for the state of Pará, five new records for the state of Amapá and one new record for the North region.

RESUMO Objetivos: Analisar os fatores associados à descontinuidade no uso de método contraceptivos após a vivência de um abortamento. Método: Estudo transversal, conduzido com 111 mulheres de 18-49 anos, usuárias de Unidades Básicas de Saúde de São Paulo/SP, Aracaju/SE e Cuiabá/MT, que relataram abortamento nos cinco anos anteriores às entrevistas realizadas entre 2015-2017. Utilizou-se Kaplan-Meier e regressão de Cox para análise dos dados. Resultados: Os métodos mais utilizados foram o contraceptivo hormonal oral, preservativo masculino e injetáveis. A taxa de descontinuidade contraceptiva foi 41,8% nos 12 meses. A pílula foi o método mais abandonado (58,3%); o preservativo masculino aquele que mais falhou (72,7%); e injetáveis os mais trocados (50,0%). Ter até 24 anos de idade, mais de 10 anos de escolaridade, três ou mais filhos e querer esperar mais para engravidar associaram-se a descontinuar o uso dos métodos contraceptivos após o abortamento. Conclusão: Após o abortamento, as mulheres usaram predominantemente métodos contraceptivos de curta duração. O tipo de descontinuidade, abandono, troca ou falha, variou conforme o método usado. Os fatores associados à descontinuidade contraceptiva foram a idade, a escolaridade, a paridade e a intenção reprodutiva.

ABSTRACT Objectives: To assess factors associated with post-abortion contraceptive discontinuation. Method: This cross-sectional study addressed 111 women aged 18-49 attending Primary Health Care Facilities in São Paulo/SP, Aracaju/SE, and Cuiabá/MT, Brazil, who reported an abortion five years before the interview held in 2015-2017. Kaplan-Meier estimates and Cox Regression were used for data analysis. Results: Oral hormonal contraceptives, male condoms, and injectable contraceptives were the methods most frequently used. The contraceptive discontinuation rate was 41.8% in the 12 months after the abortion. The pill was the method most frequently abandoned (58.3%); male condoms were the method that failed the most (72.7%), and injectable contraceptives were the method most frequently switched (50.0%). Being up to 24 years old, having ten or more years of education, having three or more children, and a desire to wait longer before becoming pregnant again were associated with post-abortion contraceptive discontinuation. Conclusion: Short-acting contraceptive methods were predominant among post-abortion women. The type of discontinuation varied according to the type of method used. The factors associated with contraceptive discontinuation were age, education, parity, and reproductive intention.

RESUMEN Objetivos: Analizar los factores asociados a la discontinuidad en el uso de métodos anticonceptivos después de un aborto. Método: Estudio transversal realizado con 111 mujeres de 18 a 49 años, usuarias de Unidades Básicas de Salud de São Paulo/SP, Aracaju/SE y Cuiabá/MT, quienes reportaron aborto en los cinco años previos a la entrevista realizada entre 2015-2017. Se utilizó Kaplan-Meier y la regresión de Cox para el análisis de datos. Resultados: Tras el aborto, los métodos utilizados se centraron en los de corta duración: anticonceptivos hormonales orales, condones masculinos e inyectables. La tasa de discontinuidad en el uso de métodos anticonceptivos fue del 41,8% en los 12 meses posteriores al aborto. La píldora fue el método que se abandonó con más frecuencia (58,3%); el condón masculino en el que ocurrieron más fallas (72,7%); e inyectables intercambiados con mayor frecuencia (50,0%). Tener 24 años o más, 10 o más años de escolaridad, alta paridad (3 o más) y desear esperar para quedar embarazada se asociaron con la discontinuidad en el uso de métodos anticonceptivos después del aborto. Conclusión: Las mujeres después de un aborto utilizaron predominantemente métodos anticonceptivos de corta duración, que con mayor frecuencia se suspenden. El tipo de discontinuidad, abandono, intercambio o falla varió según el tipo de método utilizado. La edad, la educación, la paridad y la intención reproductiva se asociaron con la discontinuidad en el uso de métodos anticonceptivos después del aborto.

Resumo Objetivo Analisar a vulnerabilidade a vivenciar uma gravidez não intencional entre mulheres usuárias de Unidades Básicas de Saúde e os aspectos associados. Métodos Estudo transversal com 470 mulheres usuárias de Unidades Básicas de Saúde da Coordenadoria Regional de Saúde Leste do município de São Paulo. Os dados foram coletados por meio de entrevistas e utilizou-se regressão logística múltipla para analisar os aspectos associados. Resultados Aproximadamente metade das mulheres mostrou estar vulnerável a vivenciar uma gravidez não intencional (48,3%). Mulheres na faixa etária de 25 a 34 anos tiveram mais chance de estar vulneráveis à gravidez não intencional comparadas às mulheres na faixa etária de 18 a 24 anos (OR=2,0; IC95% 1,2-3,4), tendo sido o mesmo observado em relação às mulheres com 35 anos de idade ou mais (OR=9,7; IC95% 5,3-17,6). As mulheres em união estável tiveram menos chance de estar vulneráveis a uma gravidez não intencional comparadas às mulheres solteiras (OR=0,4; IC95% 0,3-0,7). As mulheres que não planejaram a gravidez anterior tinham mais chance de estar vulnerável a uma gravidez não intencional comparadas às mulheres que planejaram a gravidez anterior (OR=2,5; IC95% 1,2-5,1), diferentemente das mulheres que nunca engravidaram (OR=0,4; IC95% 0,2-0,7). Conclusão Uma parcela significativa de mulheres estava vulnerável a vivenciar uma gravidez não intencional. Os aspectos associados a vivenciar uma gravidez não intencional foram a idade, não estar em união estável e não ter planejado a última gravidez.

Abstract Objective To analyze the vulnerability to experience an unintentional pregnancy among women users of Primary Care Centers and the associated aspects. Methods A cross-sectional study with a total of 470 women users of Primary Care Centers of the East Health Supervision Department from the city of Sao Paulo. Data were collected through interviews and multiple logistic regression was used to analyze the associated aspects. Results Approximately half of the women were found to be vulnerable to experiencing an unintentional pregnancy (48.3%). Women aged 25 to 34 years old were more likely to be vulnerable to unintentional pregnancy compared to women aged 18 to 24 years old (OR=2.0; 95%CI 1.2-3.4), the same observed for women aged 35 years old or older (OR=9.7; 95%CI 5.3-17.6). Women in a stable relationship were less likely to be vulnerable to an unintentional pregnancy compared to single women (OR=0.4; 95%CI 0.3-0.7). Women who did not plan a previous pregnancy were more likely to be vulnerable to an unintentional pregnancy compared to women who planned a previous pregnancy (OR=2.5; 95%CI 1.2-5.1), unlike women who never got pregnant (OR=0.4; 95%CI 0.2-0.7). Conclusion A significant portion of women was vulnerable to experiencing an unintentional pregnancy. The aspects associated with experiencing this pregnancy were age, not being in a stable relationship and not having planned the last pregnancy.

Lo mismo se ha observado en relación con las mujeres de 35 años o más (OR=9,7; IC95 % 5,3-17,6). Las mujeres en unión de hecho tuvieron menos posibilidades de vulnerabilidad a un embarazo no intencional en comparación con las mujeres solteras (OR=0,4; IC95 % 0,3-0,7). Las mujeres que no planificaron el embarazo anterior tuvieron más posibilidades de estar vulnerables a un embarazo no intencional cuando comparadas con las mujeres que planificaron el embarazo anterior (OR=2,5; IC95 % 1,2-5,1), a diferencia de las mujeres que nunca habían quedado embarazadas (OR=0,4; IC95 % 0,2-0,7). Conclusión Una parte significativa de las mujeres estaba vulnerable a vivir un embarazo no intencional. Los aspectos asociados a la vivencia de un embarazo no intencional fueron la edad, no tener una unión de hecho y no haber planificado el último embarazo.

Abstract To characterize the floristic composition and horizontal structure of the National Forest of Açú from 2015 to 2019, 20 permanent plots of 400 m² were allocated, and all woody individuals with a diameter at breast height (CBH) ≥ 2 cm were measured on both occasions. Between 2015 and 2019, there was an increase in floristic richness from 23 to 34 species, especially Cenostigma pyramidale and Handroanthus impetiginosus due to their high phytosociological values. Although an 8.7% reduction in the number of individuals in the 4.4 cm class center was observed between the respective years, there was a volumetric increase of 4.85 m³ ha-1, that is 1.21 m³ ha-1 year-1. Changes in floristic composition, diameter distribution, and volumetry reflect the development of vegetation and part of its dynamics; indicating its state of conservation and, consequently, the achievement of the conservation objectives proposed by the Unit.
