Meanings attributed to health-related quality of life by caregivers of adolescents with diabetes.

OBJECTIVE: to interpret the meanings attributed to the health-related quality of life by caregivers of adolescents with type 1 diabetes mellitus. METHODS: qualitative, descriptive-exploratory study of 14 caregivers of adolescents with diabetes developed at the reference outpatient clinic for endocrine diseases in a city in the state of Paraíba. Interviews were performed between May and September 2021. Inductive thematic analysis of the empirical material, and its interpretation in light of the concepts of health-related quality of life and family functioning were performed. RESULTS: the meanings attributed by caregivers to the health-related quality of life of adolescents converged on the feeling of being healthy, healthy eating, satisfactory family income, family involvement in care and effective access to the care network. FINAL CONSIDERATIONS: knowledge of these meanings enables health professionals to develop strategies that meet the unique demands of caregivers experiencing this diagnosis.

Lockdown during the COVID-19 pandemic: lessons from a polarized scenario in Brazil.

Introduction: The COVID-19 pandemic led many countries to adopt strict measures aimed at reducing circulation of the virus and mitigating the burden on health services. Among these, the lockdown (social distancing/confinement) was probably the most controversial and most widely debated, since it affected the population's daily life abruptly, with consequences for people's emotional state and the operational logic of various economic sectors. Objective: Analyze the relationship been Brazilians' opinions on lockdown during the pandemic and individual, sociodemographic, and belief characteristics. Methods: We conducted an online survey to evaluate Brazilians' opinions on the lockdown during the COVID-19 pandemic. We prepared a questionnaire with questions on sociodemographic aspects and individuals' points of view toward the lockdown. We sent a link for the survey through social media and encouraged participants to also share the link in their respective social networks, as a snowball sample. Cluster analysis was performed to identify different opinion profiles. Cluster Analysis is a multivariate approach that aims to segment a set of data into distinct groups, using some classification criteria. Results: From April to May 2021, the link received 33,796 free participations via social networks from all over Brazil. We analyzed data from 33,363 participants. Pro-lockdown opinions predominated in most of the sociodemographic strata. Cluster analysis identified two groups: pro-lockdown, aligned with the scientific recommendations, and anti-lockdown, characterized by economic insecurity and denialism. Anti-lockdown participants downplayed the pandemic's seriousness and believed in unproven measures to fight SARS-CoV-2. However, these same participants were afraid of losing their jobs and of being unable to pay their bills. In general, participants did not believe in the feasibility of a lockdown in Brazil or in the efficacy of the prevailing government administration's measures. Conclusion: The study identified a lack of consensus among participants concerning lockdown as a practice. Issues such as disbelief in the pandemic's seriousness, denialism, and economic insecurity were important in the determination of the profiles identified in the study. Denialism is believed to have been a subjective defense against the economic problems resulting from social control measures and the lack of adequate social policies to deal with the pandemic. It was also highlighted that political polarization and the lack of central coordination during social distancing are crucial aspects. The variation in results in different locations highlights the diversity of the Brazilian scenario. By analyzing Brazilians' opinions about the lockdown, considering individual characteristics, the study seeks insights to face the pandemic and prepare for future crises, contributing to more effective public health strategies.

Intensity and lifetime ratiometric luminescent thermometer based on a Tb(III) coordination polymer.

A three-dimensional terbium(III) coordination polymer of formula [Tb(bttb)0.5(2,5-pzdc)0.5]n (1) [H4bttb = 1,2,4,5-tetrakis(4'-carboxyphenyl)benzene and H2-2,5-pzdc = 2,5-pyrazinedicarboxylic acid] was obtained under hydrothermal conditions. The bttb4- tetraanion in 1 adopts the bridging and chelating-bridging pseudo-oxo coordination modes while the 2,5-pzdc2- dianion exhibits a rather unusual bis-bidentate bridging pseudo-oxo coordination mode, both ligands being responsible for the stiffness of the resulting 3D structure. Solid-state photoluminescent measurements illustrate that 1 exhibits remarkable green luminescence emission, the most intense band occurring in the region of 550 nm (5D4 → 7F5) with lifetimes at the millisecond scale. Thermometric performances of 1 reveal a maximum relative sensitivity (Sm) of 0.76% K-1 at 295 K (δT = 0.05 K), constituting a TbIII ratiometric solid luminescent thermometer over the physiological temperature range. Variable-temperature static (dc) magnetic susceptibility measurements for 1 in the temperature range 2.0-300 K show the expected behavior for the depopulation of the splitted mJ levels of the 7F7 ground state of the magnetically anisotropic terbium(III) ion plus a weak antiferromagnetic interaction through the carboxylate bridges. No significant out-of-phase magnetic susceptibility signals were observed for 1 in the temperature range 2.0-10.0 K, either in the absence or presence of a static dc magnetic field.

Estratégia materna de enfrentamento à confirmação de infecção pelo vírus Zika na gravidez: reflexo no neurodesenvolvimento dos seus filhos / Maternal strategy for coping with confirmation of Zika virus infection during pregnancy: reflection on the neurodevelopment of their children

Resumo A infecção pelo vírus Zika na grávida resulta em alterações do desenvolvimento neuropsicomotor nas crianças afetadas, sendo importante fator de estresse para essas mulheres. O objetivo deste estudo foi avaliar a estratégia de enfrentamento das mães a essa situação e como isto se refletiu no neurodesenvolvimento dos seus filhos. Estudo transversal com 46 mulheres e seus filhos. A estratégia de enfrentamento foi avaliada pelo Inventário Brief Cope, aplicado às mães, e o desenvolvimento neuropsicomotor das crianças, foi avaliado aos 24 meses de idade pelas Escalas Bayley III. A estratégia predominante de enfrentamento mais frequentemente usada pelas mães foi a de aproximação (73,9%), com destaque para o componente planejamento. A utilização da estratégia de negação esteve associada aos escores mais baixos na escala Bayley III, sendo nessa escala o componente mais utilizado o de auto culpabilização. A religião foi o componente de apoio auxiliar mais utilizado pelas mães. A utilização da negação como estratégia predominante de enfrentamento pelas mães mostrou associação com os piores resultados na avaliação do desenvolvimento infantil e reforça a necessidade do apoio a estas mulheres, para que possam lidar mais diretamente com os sentimentos decorrentes das situações vivenciadas.

Abstract Zika virus infection in pregnant women results in changes in neuropsychomotor development in affected children, being an important stress factor for these women. This study aimed to evaluate the mothers' coping strategy in this situation and how this was reflected in the neurodevelopment of their children. Cross-sectional study with 46 women and their children. The coping strategy was assessed using the Brief Cope Inventory, applied to mothers, and the children's neuropsychomotor development was assessed at 24 months of age using the Bayley III Scales. The predominant coping strategy most frequently used by mothers was approach (73.9%), with emphasis on the planning component. The use of the avoidant coping was associated with lower scores on the Bayley III scale, with self-blame being the most used component on this scale. Religion was the auxiliary support component most used by mothers. The use of avoidant as the predominant coping strategy by mothers was associated with the worst results in the assessment of child development and reinforces the need to support these women, so that they can deal more directly with the feelings arising from the situations they experience.

Look, you are (not) alone: circulating gift and the mental health of healthcare professionals during the COVID-19 pandemic. / Olha, você (não) está sozinho: a circulação da dádiva e a saúde mental de profissionais de saúde durante a pandemia de COVID-19.

The mental health of health professionals who worked directly in services during the COVID-19 pandemic to care for patients affected by the disease became a fundamental issue to be considered, given the several consequences of this activity for these professionals. This article aimed to understand the challenges and demands of health professionals concerning support to address the emotional and physical exhaustion of working on the so-called frontline during the COVID-19 pandemic. The qualitative methodological approach was based on semi-structured interviews conducted online with these professionals after the first months of the pandemic. The hero's place in which they were set, even if only in media discourses, soon gave way to their weaknesses and fragile work relationships to emerge: stress, fear, and the listening and reception desire. Marcel Mauss' gift theory was brought up considering that new ways of reading and interpreting health work relationships contribute to necessary and urgent reformulations of their current context, targeting mental health and, more broadly, the comprehensive health of healthcare professionals.

Durante a pandemia de COVID-19, a saúde mental dos profissionais de saúde, que trabalharam diretamente nos serviços voltados para o cuidado dos pacientes afetados pela doença, tornou-se questão fundamental a ser considerada, dado os diversos desdobramentos que essa atuação gerou para esses profissionais. O objetivo deste artigo foi compreender desafios e demandas dos profissionais de saúde em termos de suporte para lidar com o desgaste emocional e físico com a atuação na chamada linha de frente durante a pandemia de COVID-19. A abordagem metodológica qualitativa se deu a partir de entrevistas semiestruturadas realizadas em ambiente online com esses profissionais, passados os primeiros meses de pandemia. O lugar de herói em que eles foram colocados, ainda que apenas nos discursos midiáticos, logo deu espaço para que as fragilidades destes e das relações de trabalho aparecessem: estresse, medo e o desejo de escuta e acolhimento. A teoria da dádiva de Marcel Mauss foi trazida considerando que novas formas de leitura e interpretação das relações de trabalho em saúde contribuem para reformulações necessárias e urgentes do contexto em que se encontram hoje, visando a saúde mental e, mais amplamente, a saúde integral dos profissionais da área de saúde.

[Online survey on the reasons for vaccine hesitancy against COVID-19 in children and adolescents in Brazil]. / Inquérito online sobre os motivos para hesitação vacinal contra a COVID-19 em crianças e adolescentes do Brasil.

The objective is to unveil the reasons for vaccine hesitancy among parents and/or guardians of children and adolescents toward the prevention of COVID-19. This is a descriptive study, with a qualitative approach that seeks to analyze the answers to the open question "Why will you not vaccinate or have not vaccinated or are in doubt about vaccinating the children and adolescents under your responsibility, for the prevention of COVID-19?". The research included adult individuals, Brazilians, living in the country, responsible for children and adolescents under 18 years of age. Data collection took place electronically in November and December 2021. The answers were organized and processed with the support of the software Iramuteq. The textual corpus of this research was composed of the response of 1,896 participants, consisting of 87% who were hesitant (1,650) and 13% (246) of parents who intend to vaccinate but who outlined some doubts and considerations about the vaccination of children and adolescents. These are reasons why parents and/or guardians have not vaccinated or are in doubt about vaccinating the children and adolescents under their responsibility for the prevention of COVID-19: fears about vaccination regarding the conception that the vaccine is in the experimental phase, fear of adverse reactions and long-term effects. The reasons for the lack of intention to vaccinate stem from the understanding of the participants that COVID-19 in children is not serious, the risks of vaccination are greater than the benefits, and the right of choice not to vaccinate.

Objetiva-se desvelar os motivos para hesitação vacinal de pais e/ou responsáveis de crianças e adolescentes para prevenção da COVID-19. Trata-se de um estudo descritivo, de abordagem qualitativa, que busca analisar as respostas da pergunta aberta "por que você não vai vacinar, não vacinou ou está na dúvida em vacinar as crianças e os adolescentes sob sua responsabilidade para prevenção da COVID-19?". A pesquisa incluiu indivíduos adultos, brasileiros, residentes no país, responsáveis por crianças e adolescentes menores de 18 anos. A coleta de dados aconteceu de forma eletrônica entre os meses de novembro e dezembro de 2021. As respostas foram organizadas e processadas com suporte do software Iramuteq. O corpus textual desta pesquisa foi composto pela resposta de 1.896 participantes, constituído por 87% de hesitantes (1.650) e 13% (246) de pais que têm intenção de vacinar, mas que esboçaram algumas dúvidas e considerações a respeito da vacinação de crianças e adolescentes. São motivos pelos quais pais e/ou responsáveis não vacinaram ou estão na dúvida em vacinar as crianças e os adolescentes sob sua responsabilidade para prevenção da COVID-19: receio em razão de a vacina estar em fase experimental e medo das reações adversas e dos efeitos a longo prazo. Já os motivos para ausência de intenção de vacinar decorrem dos entendimentos dos participantes de que a COVID-19 em crianças não é grave, os riscos da vacinação são maiores do que os benefícios e o direito de escolha em não vacinar.

El objetivo es revelar los motivos de la indecisión a las vacunas de padres y/o responsables de niños y adolescentes para la prevención de COVID-19. Se trata de un estudio descriptivo con enfoque cualitativo, que busca analizar las respuestas a la pregunta abierta "¿Por qué no va a vacunar o no vacunó o tiene dudas en vacunar a los niños y los adolescentes bajo su responsabilidad para la prevención del COVID-19?". La investigación incluyó individuos adultos, brasileños, residentes en el país, responsables de niños y adolescentes menores de 18 años. La recolección de datos se realizó de forma electrónica entre los meses de noviembre y diciembre de 2021. Las respuestas se organizaron y procesaron con ayuda del software Iramuteq. El corpus textual de esta investigación fue compuesto por la respuesta de 1.896 participantes, siendo constituido por el 87% de indecisos (1.650) y el 13% (246) de padres que tienen la intención de vacunar, pero que esbozaron algunas dudas y consideraciones respecto a la vacunación de niños y adolescentes. Son motivos por los cuales los padres y/o responsables no vacunaron o están en duda en vacunar a los niños y adolescentes bajo su responsabilidad para prevención del COVID-19: temores con la vacunación en cuanto a la concepción de que la vacuna está en fase experimental, miedo a las reacciones adversas y los efectos a largo plazo. Los motivos de la ausencia de intención en vacunar se deben a que los participantes entienden que el COVID-19 en niños no es grave, que los riesgos de la vacunación son mayores que los beneficios y que tienen derecho a decidir no vacunarse.

Social Representations of Hesitant Brazilians about Vaccination against COVID-19.

BACKGROUND: The control of the COVID-19 pandemic has been a great challenge. Understanding the thoughts and beliefs underlying vaccine hesitancy can help in the formulation of public policies. The present study aimed to analyze the social representations of hesitant Brazilians about vaccination against COVID-19. METHODS: Qualitative research guided by the Theory of Social Representations, carried out through an online survey among Brazilian adults living in Brazil. The data were analyzed using the IRaMuTeQ software. RESULTS: Of the 173,178 respondents, 10,928 were hesitant and declared reasons for vaccination hesitation. The analysis generated three classes: mistrust of the vaccine and underestimation of the severity of the pandemic; (dis)information and distrust of political involvement; and fear of adverse reactions to COVID-19 vaccines. CONCLUSIONS: Social knowledge, presented by the representations apprehended in this study, demonstrates difficulty in discerning the reliability of information and a social imagination full of doubts and uncertainties. Understanding the internal dynamics of these groups, with their representations of the world, is important to propose policies and actions that echo and cause changes in the understanding of the role of immunization. It is essential to shed light on the sociological imagination so that gaps filled with false information can be dismantled and confronted with scientific knowledge accessible to the population.

Reports by explorers and travelers and the first scientific studies on ayahuasca (dating from 1850 to 1950) within the current debate on the "psychedelic renaissance". / Relatos de exploradores e viajantes e primeiras pesquisas científicas com a ayahuasca, 1850-1950, no debate atual sobre o "renascimento psicodélico".

This article describes the associations and controversies between indigenous and western uses of ayahuasca between 1850 and 1950 in relation to the "psychedelic renaissance." This movement has gained scientific attention since 2000, but hearkens back to the 1960s and 1970s, when anti-drug policy halted research on the "therapeutic potential" of psychoactive substances. Pioneering studies on ayahuasca date back to the early twentieth century and mention reports of expeditions to Amazonia from 1850 onward. Here, these articles and reports are analyzed according to the historical aspect of actor-network theory and recent studies. We infer that history casts light on the current political debate about indigenous uses, classifications, and meanings, pharmaceutical interest in ayahuasca, and the debate on "drugs."

O artigo descreve associações e controvérsias entre usos indígenas e ocidentais da ayahuasca, de 1850 a 1950, na relação com o "renascimento psicodélico". Destaque na ciência desde 2000, esse movimento faz referência a 1960-1970, quando políticas antidrogas suspenderam pesquisas sobre "potenciais terapêuticos" de substâncias psicoativas. Argumenta-se que estudos pioneiros com a ayahuasca datam do início do século XX e mencionam relatos de expedições à Amazônia desde 1850. Esses artigos e relatos são analisados pelo aspecto histórico da teoria do ator-rede e de estudos recentes. Infere-se que a história ilumina o debate político atual sobre os usos, classificações e significados indígenas; o interesse farmacêutico na ayahuasca; e a discussão sobre "drogas".

Study of the Counter Cation Effects on the Supramolecular Structure and Electronic Properties of a Dianionic Oxamate-Based {NiII2} Helicate.

Herein, we describe the synthesis, crystal structure, and electronic properties of {[K2(dmso)(H2O)5][Ni2(H2mpba)3]·dmso·2H2O}n (1) and [Ni(H2O)6][Ni2(H2mpba)3]·3CH3OH·4H2O (2) [dmso = dimethyl sulfoxide; CH3OH = methanol; and H4mpba = 1,3-phenylenebis(oxamic acid)] bearing the [Ni2(H2mpba)3]2- helicate, hereafter referred to as {NiII2}. SHAPE software calculations indicate that the coordination geometry of all the NiII atoms in 1 and 2 is a distorted octahedron (Oh) whereas the coordination environments for K1 and K2 atoms in 1 are Snub disphenoid J84 (D2d) and distorted octahedron (Oh), respectively. The {NiII2} helicate in 1 is connected by K+ counter cations yielding a 2D coordination network with sql topology. In contrast to 1, the electroneutrality of the triple-stranded [Ni2(H2mpba)3] 2- dinuclear motif in 2 is achieved by a [Ni(H2O)6]2+ complex cation, where the three neighboring {NiII2} units interact in a supramolecular fashion through four R22(10) homosynthons yielding a 2D array. Voltammetric measurements reveal that both compounds are redox active (with the NiII/NiI pair being mediated by OH- ions) but with differences in formal potentials that reflect changes in the energy levels of molecular orbitals. The NiII ions from the helicate and the counter-ion (complex cation) in 2 can be reversibly reduced, resulting in the highest faradaic current intensities. The redox reactions in 1 also occur in an alkaline medium but at higher formal potentials. The connection of the helicate with the K+ counter cation has an impact on the energy levels of the molecular orbitals; this experimental behavior was further supported by X-ray absorption near-edge spectroscopy (XANES) experiments and computational calculations.

Usefulness of the Hospital Information System for maternal mortality surveillance in Brazil. / Utilidade do Sistema de Informação Hospitalar na vigilância da mortalidade materna no Brasil.

OBJECTIVE: To evaluate the capability of hospital records in the Hospital Information System (SIH) to add valuable and complementary information to the Mortality Information System (SIM) in studies on maternal mortality. We calculated and compared the maternal mortality ratio from the SIH and SIM databases, by age group and region, to highlight differences between groups and assess the coverage of maternal deaths using SIH compared with SIM. METHODS: Obstetric hospitalizations were defined based on three sources (codes ICD-10 in diagnoses; procedures; billing information). Hospital and SIM mortality ratios were calculated by dividing maternal deaths in hospitals affiliated to the Unified Brazilian Health System (SUS) per live births (SINASC) in the same hospitals. RESULTS: In 2019, we identified 2,497,957 obstetric admissions, 0.04% (946) with in-hospital mortality as outcome. The presence of three criteria identified 98% of obstetric hospitalizations and 83% of obstetric hospitalizations with death as outcome. The comparison of mortality ratios between SIH (45.5 MMR; 95%CI 42.7 - 48.5) and SIM (49.7 MMR; 95%CI 46.7 - 52.8) was not statistically significant (p-value: 0.053). CONCLUSION: The analysis of SIH was able to provide additional information for the monitoring and surveillance of maternal health in Brazil. Although there are differences between the mortality rates, the SIH, as a complementary information system to the SIM, may be valid in studies on maternal mortality and morbidity.

OBJETIVO: Avaliar a capacidade dos registros hospitalares (SIH) em adicionar informações úteis e complementares ao Sistema de Informações sobre Mortalidade (SIM) no entendimento da mortalidade materna. Calcular e comparar a Razão de Mortalidade Materna (RMM) hospitalar e a RMM do SIM dos óbitos maternos ocorridos em hospitais, por faixa etária e por região, para demonstrar diferenças entre os grupos e avaliar a cobertura de óbitos maternos do SIM em relação ao SIH. MÉTODOS: As internações obstétricas foram definidas com base em três critérios (códigos da 10a Revisão da Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde ­ CID-10 nos diagnósticos; procedimentos; cobrança de parto). As RMM hospitalar e do SIM foram calculadas dividindo-se os óbitos maternos ocorridos nos hospitais conveniados ao Sistema Único de Saúde (SUS) pelos nascidos vivos (Sistema de Informação sobre Nascidos Vivos ­ SINASC) desses estabelecimentos. RESULTADOS: Em 2019, identificamos 2.497.957 registros de internações obstétricas, 0,04% (946) com óbito hospitalar. Os três critérios localizaram 98% das internações obstétricas e 83% das internações com óbitos, revelando inconsistências entre diagnósticos e procedimentos. A comparação entre a RMM do SIH (45,5, intervalo de confiança ­ IC95%, 42,7­48,5) e a do SIM (49,7, IC95%, 46,7­52,8) não foi estatisticamente significante (p-valor 0,053). CONCLUSÃO: A análise do SIH foi capaz de prover informações adicionais ao monitoramento e vigilância da saúde materna no Brasil. Embora haja diferenças entre as RMM, o SIH como sistema de informação complementar ao SIM pode ser válido nos estudos sobre mortalidade e morbidade materna.

Trustworthiness of information sources on vaccines for COVID-19 prevention among Brazilians.

OBJECTIVE: This study aims to assess the trustworthiness of information sources, perception of clear information about the vaccine, and strategies to increase adherence to vaccination to provide managers with information that helps establish effective communication with the population about vaccination. METHOD: This is an online survey conducted between January 22 and 29, 2021, preceded by an Informed Consent, that aims to assess vaccine hesitancy, which corresponded to the first week of vaccination initiation to prevent COVID-19 in Brazil. Data were obtained from a questionnaire made available through a free platform and stored in Google Forms and later exported to the SPSS statistical package for analysis. The sample consisted of all questionnaires from participants who self-declared as age 18 or older, Brazilian, and residing in Brazil at the time of the survey. Incomplete records with more than 50% of blank items and duplicates were excluded. All categorical variables were analyzed from their absolute and relative frequencies. Multivariate logistic regression was performed to verify the relationship between dependent variables and independent variables. RESULTS: The results show that trust in information sources diverges between hesitant and non-hesitant. They also showed that some participants show an overall distrust that seems to have deeper foundations than issues related only to the source of information. The high rejection of television and the WHO as sources of information among hesitant suggests that integrated actions with research institutes, public figures vaccinating, and religious leaders can help to combat vaccine hesitation. Two actors become particularly important in this dynamic, both for good and bad, and their anti-vaxxer behavior must be observed: the doctor and the Ministry of Health. CONCLUSION: This study contributes to gathering valuable information to help understand the behavior and thinking relevant to the adherence to vaccination recommendations.

Willingness of Brazilian caregivers in having their children and adolescents vaccinated against Covid-19.

BACKGROUND: The vaccination of children and adolescents for the prevention of Covid-19 is important to:decrease in deaths and hospitalizations, prevent multisystem inflammatory syndrome, avoid long-term complications and decrease the suspension of on-site classes. Despite of these benefits, some studies have shown that some caregivers are still hesitancy. METHODS: This is a voluntary and anonymous online survey conducted from November 17 to December 14, 2021, in Brazil, through a free-of-charge platform with a link provided on social networks. A bivariate analysis was conducted with the independent variables, with vaccine hesitancy as the outcome variable, and a multivariate logistic model was used to calculated adjusted odds ratios. RESULTS: The sample included 15,297 respondents. Approximately 13.3 % (2,028) of the caregivers were hesitant to vaccinate their children and adolescents against Covid-19 in at least one age group. The vaccination hesitanty rate of caregivers of children aged 0-4 years, 5-11 years and adolescents were 16 %, 13 %, 15 %, respectively. The principal factors associated with vaccine hesitancy were the following: belief that they need to wait longer, belief that children that had natural infection doesn't need to vaccinate and belief that vaccine has long term adverse effects. INTERPRETATION: The present study showed that the willingness of caregivers to have their children and adolescents vaccinated in Brazil is high compared to data from adult and pediatric international studies. This study provides a profile of the hesitant caregivers considering their perspectives and beliefs regarding vaccines that can help the elaboration of strategies to increase vaccine adherence.

Hospital and SIM mortality ratios were calculated by dividing maternal deaths in hospitals affiliated to the Unified Brazilian Health System (SUS) per live births (SINASC) in the same hospitals. Results: In 2019, we identified 2,497,957 obstetric admissions, 0.04% (946) with in-hospital mortality as outcome. The presence of three criteria identified 98% of obstetric hospitalizations and 83% of obstetric hospitalizations with death as outcome. The comparison of mortality ratios between SIH (45.5 MMR; 95%CI 42.7 - 48.5) and SIM (49.7 MMR; 95%CI 46.7 - 52.8) was not statistically significant (p-value: 0.053). Conclusion: The analysis of SIH was able to provide additional information for the monitoring and surveillance of maternal health in Brazil. Although there are differences between the mortality rates, the SIH, as a complementary information system to the SIM, may be valid in studies on maternal mortality and morbidity.

Bottom/top hardness ratio and dentin bonding stability of conventional and bulk-fill resin composites

Aim: To evaluate the bottom/top hardness ratio (B/T) and the dentin bonding stability of conventional and bulk-fill resin composites in high c-factor preparations. Methods: Regular conventional (Tetric N-Ceram ­ TNC, and Polofil Supra ­ PFS), regular bulk-fill (Tetric N-Ceram Bulk fill ­ TBF, and Admira Fusion X-tra ­ AFX), and low viscosity bulk-fill resin composites (Tetric N-flow ­ TNF, and X-tra Base ­ XTB) were used to restore 180 dentin conical preparations. The specimens were randomly distributed in 12 groups (n = 15) according to the resin composites and storage time-points (24 h and six months) tested. After 24 h storage, all specimens were subjected to the bottom/top hardness ratio analysis. Then, the push-out bond strength test was performed in half of the specimens and the other half were maintained for six months on water storage before testing. The failure modes were analyzed in a stereomicroscopic. The data were analyzed statistically using one- and two-way ANOVA and Tukey post-test (p <0.05). Results: There were no statistically significant differences for the bottom/top hardness ratio among the resin composites (p>0.05). Regardless of the storage timepoint, regular bulk-fill resin composites showed the highest bond strength values statistically (p<0.05). Only conventional resin composites showed statistically lower bond strength values at six-month storage (p<0.05). Adhesive failures were more predominant for low-viscosity bulk-fill resin composites. Conclusion: Although the DoC was not affected by different materials tested, only bulk-fill resin composites did not present dentin bond strength loss after six-month of water storage

Relatos de exploradores e viajantes e primeiras pesquisas científicas com a ayahuasca, 1850-1950, no debate atual sobre o "renascimento psicodélico" / Reports by explorers and travelers and the first scientific studies on ayahuasca (dating from 1850 to 1950) within the current debate on the "psychedelic renaissance"

Resumo O artigo descreve associações e controvérsias entre usos indígenas e ocidentais da ayahuasca, de 1850 a 1950, na relação com o "renascimento psicodélico". Destaque na ciência desde 2000, esse movimento faz referência a 1960-1970, quando políticas antidrogas suspenderam pesquisas sobre "potenciais terapêuticos" de substâncias psicoativas. Argumenta-se que estudos pioneiros com a ayahuasca datam do início do século XX e mencionam relatos de expedições à Amazônia desde 1850. Esses artigos e relatos são analisados pelo aspecto histórico da teoria do ator-rede e de estudos recentes. Infere-se que a história ilumina o debate político atual sobre os usos, classificações e significados indígenas; o interesse farmacêutico na ayahuasca; e a discussão sobre "drogas".

Abstract This article describes the associations and controversies between indigenous and western uses of ayahuasca between 1850 and 1950 in relation to the "psychedelic renaissance." This movement has gained scientific attention since 2000, but hearkens back to the 1960s and 1970s, when anti-drug policy halted research on the "therapeutic potential" of psychoactive substances. Pioneering studies on ayahuasca date back to the early twentieth century and mention reports of expeditions to Amazonia from 1850 onward. Here, these articles and reports are analyzed according to the historical aspect of actor-network theory and recent studies. We infer that history casts light on the current political debate about indigenous uses, classifications, and meanings, pharmaceutical interest in ayahuasca, and the debate on "drugs."

Inquérito online sobre os motivos para hesitação vacinal contra a COVID-19 em crianças e adolescentes do Brasil / Online survey on the reasons for vaccine hesitancy against COVID-19 in children and adolescents in Brazil / Encuesta en línea sobre los motivos de la indecisión a las vacunas contra COVID-19 en niños y adolescentes de Brasil

Resumo: Objetiva-se desvelar os motivos para hesitação vacinal de pais e/ou responsáveis de crianças e adolescentes para prevenção da COVID-19. Trata-se de um estudo descritivo, de abordagem qualitativa, que busca analisar as respostas da pergunta aberta "por que você não vai vacinar, não vacinou ou está na dúvida em vacinar as crianças e os adolescentes sob sua responsabilidade para prevenção da COVID-19?". A pesquisa incluiu indivíduos adultos, brasileiros, residentes no país, responsáveis por crianças e adolescentes menores de 18 anos. A coleta de dados aconteceu de forma eletrônica entre os meses de novembro e dezembro de 2021. As respostas foram organizadas e processadas com suporte do software Iramuteq. O corpus textual desta pesquisa foi composto pela resposta de 1.896 participantes, constituído por 87% de hesitantes (1.650) e 13% (246) de pais que têm intenção de vacinar, mas que esboçaram algumas dúvidas e considerações a respeito da vacinação de crianças e adolescentes. São motivos pelos quais pais e/ou responsáveis não vacinaram ou estão na dúvida em vacinar as crianças e os adolescentes sob sua responsabilidade para prevenção da COVID-19: receio em razão de a vacina estar em fase experimental e medo das reações adversas e dos efeitos a longo prazo. Já os motivos para ausência de intenção de vacinar decorrem dos entendimentos dos participantes de que a COVID-19 em crianças não é grave, os riscos da vacinação são maiores do que os benefícios e o direito de escolha em não vacinar.

Abstract: The objective is to unveil the reasons for vaccine hesitancy among parents and/or guardians of children and adolescents toward the prevention of COVID-19. This is a descriptive study, with a qualitative approach that seeks to analyze the answers to the open question "Why will you not vaccinate or have not vaccinated or are in doubt about vaccinating the children and adolescents under your responsibility, for the prevention of COVID-19?". The research included adult individuals, Brazilians, living in the country, responsible for children and adolescents under 18 years of age. Data collection took place electronically in November and December 2021. The answers were organized and processed with the support of the software Iramuteq. The textual corpus of this research was composed of the response of 1,896 participants, consisting of 87% who were hesitant (1,650) and 13% (246) of parents who intend to vaccinate but who outlined some doubts and considerations about the vaccination of children and adolescents. These are reasons why parents and/or guardians have not vaccinated or are in doubt about vaccinating the children and adolescents under their responsibility for the prevention of COVID-19: fears about vaccination regarding the conception that the vaccine is in the experimental phase, fear of adverse reactions and long-term effects. The reasons for the lack of intention to vaccinate stem from the understanding of the participants that COVID-19 in children is not serious, the risks of vaccination are greater than the benefits, and the right of choice not to vaccinate.

Resumen: El objetivo es revelar los motivos de la indecisión a las vacunas de padres y/o responsables de niños y adolescentes para la prevención de COVID-19. Se trata de un estudio descriptivo con enfoque cualitativo, que busca analizar las respuestas a la pregunta abierta "¿Por qué no va a vacunar o no vacunó o tiene dudas en vacunar a los niños y los adolescentes bajo su responsabilidad para la prevención del COVID-19?". La investigación incluyó individuos adultos, brasileños, residentes en el país, responsables de niños y adolescentes menores de 18 años. La recolección de datos se realizó de forma electrónica entre los meses de noviembre y diciembre de 2021. Las respuestas se organizaron y procesaron con ayuda del software Iramuteq. El corpus textual de esta investigación fue compuesto por la respuesta de 1.896 participantes, siendo constituido por el 87% de indecisos (1.650) y el 13% (246) de padres que tienen la intención de vacunar, pero que esbozaron algunas dudas y consideraciones respecto a la vacunación de niños y adolescentes. Son motivos por los cuales los padres y/o responsables no vacunaron o están en duda en vacunar a los niños y adolescentes bajo su responsabilidad para prevención del COVID-19: temores con la vacunación en cuanto a la concepción de que la vacuna está en fase experimental, miedo a las reacciones adversas y los efectos a largo plazo. Los motivos de la ausencia de intención en vacunar se deben a que los participantes entienden que el COVID-19 en niños no es grave, que los riesgos de la vacunación son mayores que los beneficios y que tienen derecho a decidir no vacunarse.

Does a Diet Rich in the Bacterium Rhodopirellula rubra Improve Daphnia magna Performance?

BACKGROUND: In the wild various organisms contribute to daphnids diet. This study, intendeds to evaluate the potential of the concentration of Rhodopirellula rubra as a single or supplementary food source for Daphnia magna. METHODS: Feeding assays were performed according to standard guidelines for chronic assays (21 days), and life-history parameters and several biomarkers (protein content, oxidative stress, energetic reserves and pigments) were measured. Five food regimens were conducted with 20 individual replicates (A - R. subcapitata; 0.2 - suspension of R. rubra at 0.2 arbitrary units (AU); 0.4 - suspension of R. rubra at 0.4 AU; 0.2+A - suspension of R. rubra at 0.2+alga; 0.2+A-suspension of R. rubra at 0.4 AU + alga). Additionally, the effects of three diets (A, 0.2, and 0.2+A) on the longevity of D. magna were assessed. RESULTS: The five diets showed a different C, N, and carotenoids composition, with an increase in the mixed diets. The results confirmed that the mixed diets improved D. magna life-history parameters. A decrease in glycogen, and the increase of haemoglobin, protein, and gluthione-S-transferase (GST) were observed. Furthermore, D. magna fed with bacterial single diets, presented worsen life history parameters and a decrease in the protein content. An induction of oxidative stress response (increased catalase and GST), and a significant decrease in lipid peroxidation and an accumulation of glycogen and carotenoids were observed. Overall, an increase in the amount of R. rubra provided to D. magna, from 0.2 AU to 0.4 AU, negatively impacted daphnid performance. No significant effects on Daphnia longevity (a 110-day assay) were observed among the three diets tested. However, a significant survival percentage and fertility (cumulative offspring is more than twice) was observed when D. magna was fed with the mixed diet. CONCLUSIONS: Results demonstrated that different diets provided a nutritional diversified food to the daphnids that induced differences in D. magna performance. The mixed diets proved to be beneficial (with increase in offspring) on D. magna performance, independently of the bacterial concentration tested. When in single diet, bacterial concentration is not nutritionally sufficient to raise D. magna even when in increased concentration.

Impact of the SARS-CoV-2 pandemic on urinary incontinence and quality of life of nulliparous women.

OBJECTIVES: To evaluate the impact of social isolation due to SARS-CoV-2 on the prevalence and severity of urinary incontinence and how this correlates with the quality of life of the nulliparous women evaluated. METHOD: Observational, longitudinal study, carried out from August/2019 to September/2020, at the Faculdade de Ciências da Saúde do Trairi/RN, with 37 nulliparous women from 18 to 35 years old, who answered the socio-anthropometric assessment, to the Incontinence Severity Index Questionnaire and King's Health Questionnaire, before and during isolation due to SARS-CoV-2. Statistical analysis: Wilcoxon test, and Spearman's correlation coefficient. Significance level p≤0.05. RESULTS: During social isolation, there was an improvement in urge incontinence (p=0.01) and in the frequency of urinary incontinence (p=0.03). The severity of urinary incontinence correlated with: general health perception (p=0.02; r=0.65); physical limitations (p=0.03; r=0.60); social (p=0.001; r=0.82). CONCLUSION: The social isolation from SARS-CoV-2 improved urge incontinence and frequency of urinary incontinence. The more severe the urinary incontinence, the worse the general health perception, physical and social limitations during isolation.
