Knowledge and attitudes of physicians in Chile toward Do-Not-Attempt-Resuscitation orders: A cross-sectional nation-wide study.

Objective: Do-Not-Attempt-Resuscitation orders originated in the early 1960s with the establishment of advanced cardiopulmonary resuscitation. These orders aim to limit therapeutic efforts in cases where it may be futile. The decision not to resuscitate a patient is a process that involves a series of ethical, legal, and clinical considerations. Still, it also requires a process in which priority is given to the patients and their autonomy. The objective of this study was to describe the knowledge and attitudes of physicians working in Chile toward Do-Not-Attempt-Resuscitation orders. Methods: A cross-sectional study was conducted, in which a digital questionnaire was sent to physicians from different regions of Chile. Quantitative variables were analyzed using measures of central tendency and dispersion (e.g., median and interquartile range), while qualitative variables were evaluated using frequencies and percentages. Results: Four hundred and thirty-one physicians completed the survey. 85.4% were familiar with the ethical and legal guidelines for cardiopulmonary resuscitation and the rights and duties of the patient. 39.2% believed that patients should have the final decision Do-Not-Attempt-Resuscitation orders, especially if they themselves requested not to be resuscitated. 87.7% mentioned that the Do-Not-Attempt-Resuscitation orders should be reassessed if the patient's prognosis improves. In addition, it was found that the decision not to resuscitate was not always discussed with the patient or their family. Conclusions: The study revealed an ethical conflict regarding Do-Not-Attempt-Resuscitation orders and their management by Chilean physicians. Therefore, it is necessary to create recommendations and provide training to guide professionals in this process, which should also involve patients and their families.

Intermediate Intercluster Bond Orders. Electronic Communication in Au38(SR)24 Superatomic Molecules.

Ligand-protected gold clusters remain potential building blocks for envisaged molecular materials. The archetypal Au38(SR)24 cluster can be viewed as a robust template for the fusion of two Au25(SR)18 - cluster units, retaining a bi-icosahedral Au23 core. Via electrochemical properties, the overall charge state can be selectively tuned, enabling the access of 14 valence electron (ve) species featuring a single intercluster bond and nearby charge from -1 to +3, achieving related species bearing 15- to 11-ve with variable intercluster bond orders. Here, we explore the characteristics of intermediate intercluster bond orders in order to provide insights into the plausible electron communication between the constituent building blocks, with Au38(SR)24, as a representative template. Our results denote a small structural variation along -1 to +3 charge states, provided by the core-protecting ligand interaction, which is enhanced towards more oxidized species. The remaining unpaired electron from intermediate intercluster bond orders of 1.5 for Au38(SR)24 1-, 1.5 for Au38(SR)24 1+, and 2.5 for Au38(SR)24 3+, holds delocalized characteristics between the building block units, favoring electron communication for conductive and cooperative cluster aggregates. Such features are relevant for the formation of molecular electronic device applications, favoring the rationalization prior to engaging in explorative synthesis of larger ligand-protected cluster aggregates.

Impact of COVID-19 Mandatory Lockdown Measures on Cognitive and Neuropsychiatric Symptoms in Persons with Alzheimer's Disease in Lima, Peru.

BACKGROUND: Neuropsychiatric symptoms (NPS) in patients with Alzheimer's disease (AD) worsened during the COVID-19 lockdowns, but their progression thereafter is unknown. We present the first longitudinal study tracking them before, during, and after restrictions. OBJECTIVES: To describe the effect of the COVID-19 mandatory lockdowns on Cognitive and Neuropsychiatric symptoms in patients with Mild Cognitive Impairment (MCI) and Alzheimer's Disease (AD). METHODS: Cohort of 48 patients with amnestic MCI and 38 with AD in Lima, Peru. They received three rounds of cognitive (RUDAS, CDR, M@T), behavioral (NPI), and functional (ADCS-ADL) assessments. We assessed the change in score means across the time points and for each domain of NPS and tracked the changes in individual patients. RESULTS: RUDAS declined 0.9 (SD 1.0) from baseline to lockdown and 0.7 (SD 1.0) after restrictions. M@T declined 1.0 (SD 1.5) from baseline to lockdown and 1.4 (SD 2.0) after restrictions. CDR worsened in 72 patients (83.72%) from baseline to post-lockdown. NPI worsened by 10 (SD 8.3) from baseline to lockdown but improved by 4.8 (SD 6.4) after restrictions. Proportionally, 81.3% of all patients had worsened NPS during the lockdowns, but only 10.7% saw an increase thereafter. Improvement was statistically significant for specific NPS domains except hallucinations, delusions, and appetite changes. Anxiety, irritability, apathy, and disinhibition returned to baseline levels. CONCLUSION: Following confinement, cognition continued to decline, but NPS demonstrated either stability or improvement. This highlights the role modifiable risk factors may have on the progression of NPS.

Cuidados paliativos: conhecimento de pacientes oncológicos e seus cuidadores / Palliative care: knowledge of cancer patients and their caregivers / Cuidados paliativos: conocimiento de los pacientes oncológicos y de sus cuidadores

Resumo O objetivo do estudo é verificar a percepção sobre cuidados paliativos, diretivas antecipadas de vontade e ordem de não reanimar de pacientes oncológicos e seus cuidadores, bem como a relação destes com os profissionais de saúde. Trata-se de pesquisa descritiva quantitativa, realizada entre 2018 e 2019 no Centro de Alta Complexidade em Oncologia de um hospital universitário brasileiro. A amostra contou com 200 participantes (100 pacientes oncológicos e 100 cuidadores informais). Os dados coletados foram armazenados no Microsoft Excel e processados pelo software SPSS. Foi possível observar o desconhecimento dos participantes sobre questões ligadas à terminalidade da vida, bem como o paradoxo entre discordância em relação à distanásia e concordância com a reanimação obstinada. Os resultados também atestam a importância dos profissionais de saúde na percepção dos cuidadores sobre a própria capacidade de exercer essa função.

Abstract The objective of this study is to verify the perception of palliative care, advance directives of will and do-not-resuscitate order of patients and their caregivers, as well as their relationship with health professionals. This is a quantitative descriptive research, carried out between 2018 and 2019 at the Center for High Complexity in Oncology of a Brazilian university hospital. The sample included 200 participants (100 cancer patients and 100 informal caregivers). The collected data were stored in Microsoft Excel and processed in the SPSS software. It was possible to observe the participants' lack of knowledge about issues related to the end of life, as well as the paradox of disagreeing with dysthanasia and agreeing with obstinate resuscitation. The results also attest to the importance of health professionals in the perception of caregivers about their own capacity to exercise this function.

Resumen Este estudio pretende comprobar la percepción sobre los cuidados paliativos, las directivas anticipadas de voluntad y el orden de no reanimar de los pacientes oncológicos y de sus cuidadores, así como su relación con los profesionales de la salud. Se trata de una investigación descriptiva cuantitativa, realizada entre el 2018 y el 2019 en el Centro de Alta Complejidad en Oncología de un hospital universitario brasileño. La muestra incluyó a 200 participantes (100 pacientes oncológicos y 100 cuidadores informales). Los datos recopilados se almacenaron en Microsoft Excel y se procesaron con el software SPSS. Se pudo observar la falta de conocimiento de los participantes sobre temas relacionados con la terminalidad de la vida, así como la incoherencia entre la desaprobación de la distanasia y la admisión de la reanimación obstinada. Los resultados también confirman la importancia de los profesionales de la salud en la percepción de los cuidadores sobre su propia capacidad para ejercer esta función.

Long-Term Care, Residential Facilities, and COVID-19: An Overview of Federal and State Policy Responses.

The COVID-19 pandemic has disproportionately affected residents and staff at long-term care (LTC) and other residential facilities in the United States. The high morbidity and mortality at these facilities has been attributed to a combination of a particularly vulnerable population and a lack of resources to mitigate the risk. During the first wave of the pandemic, the federal and state governments received urgent calls for help from LTC and residential care facilities; between March and early June of 2020, policymakers responded with dozens of regulatory and policy changes. In this article, we provide an overview of these responses by first summarizing federal regulatory changes and then reviewing state-level executive orders. The policy and regulatory changes implemented at the federal and state levels can be categorized into the following 4 classes: (1) preventing virus transmission, which includes policies relating to visitation restrictions, personal protective equipment guidance, and testing requirements; (2) expanding facilities' capacities, which includes both the expansion of physical space for isolation purposes and the expansion of workforce to combat COVID-19; (3) relaxing administrative requirements, which includes measures enacted to shift the attention of caretakers and administrators from administrative requirements to residents' care; and (4) reporting COVID-19 data, which includes the reporting of cases and deaths to residents, families, and administrative bodies (such as state health departments). These policies represent a snapshot of the initial efforts to mitigate damage inflicted by the pandemic. Looking ahead, empirical evaluation of the consequences of these policies-including potential unintended effects-is urgently needed. The recent availability of publicly reported COVID-19 LTC data can be used to inform the development of evidence-based regulations, though there are concerns of reporting inaccuracies. Importantly, these data should also be used to systematically identify hot spots and help direct resources to struggling facilities.

Insect (Hexapoda) diversity in the oceanic archipelago of Fernando de Noronha, Brazil: updated taxonomic checklist and new records

ABSTRACT Hexapods, commonly known as insects, are a neglected taxonomic group in the Fernando de Noronha archipelago, with unanswered questions about their species richness and the ecological processes in which they are involved (e.g., colonization, introduction, establishment, and extinction). Herein, we provide an updated Hexapod checklist with current nomenclatural combinations. The entomofauna of the Fernando de Noronha archipelago is currently composed of 453 species in 21 orders. The orders, and their respective number of species, are: Blattaria (9), Coleoptera (118), Collembola (29), Dermaptera (3), Diplura (1), Diptera (134), Embioptera (1), Hemiptera (29), Hymenoptera (59), Isoptera (2), Lepidoptera (25), Mantodea (1), Neuroptera (3), Odonata (5), Orthoptera (11), Phasmatodea (1), Phthiraptera (6), Psocoptera (3), Siphonaptera (1), Thysanoptera (10), and Zygentoma (2). The archipelago has 263 new taxon records (family + genera + species). Thirty-eight species (3.39%) were described from local specimens and most of them are likely endemic species. This study more than doubles our knowledge (from the previous 190 records) of the entomofauna in this large Brazilian archipelago. This study also provides a baseline for studies on its conservation status and for implementing future environmental management programs.

Do-not-resuscitate and treatment limitation decisions - Six years of experience from a Portuguese General Intensive Care Unit

SUMMARY OBJECTIVE Treatment limitation, as well as do-not-resuscitate (DNR) directives, are difficult but important to improve patients' quality of life and minimize dysthanasia. We aimed to study the approach to withholding, withdrawal, and DNR decisions, patients' characteristics, and process documentation in a general Intensive Care Unit (ICU) in Portugal. METHODS A retrospective analysis of data regarding the limitation of treatment decisions collected from previously-designed forms and complemented by medical record consultation. RESULTS A total of 1602 patients were admitted to the ICU between 2011 and 2016. DNR decisions were documented in 127 cases (7.9%). Patients with treatment limitations were older and had higher Simplified Acute Physiology Score II. The most frequent diagnosis preceding these decisions was sepsis (52.0%, n = 66); the most common main reason for limiting treatment was a poor prognosis of acute illness. Of the patients to whom a DNR was implemented, 117 (92.1%) died in the ICU (40.1% of the total number of ICU deaths), and hospital mortality was 100%. Participants in these decisions, as well as types of treatment withdrawn and their respective timings, were not registered in medical records. CONCLUSION Treatment limitation and DNR decisions were relatively common, in line with other Southern European studies, but behind Northern European and North American centers. Patients with these limitations were older and more severely ill than patients without such decisions. Documentation of these processes should be clear and detailed, either in specific forms or computerized clinical records; there is room for improvement in this area.

RESUMO OBJETIVO Decisões de limitação terapêutica (DLT) e de não reanimação (DNR) são difíceis, mas importantes, visando melhorar a qualidade de vida dos doentes e minimizar distanásia. O objetivo deste estudo foi avaliar a abordagem das DNR e DLT, as características dos doentes e a documentação dessas decisões numa Unidade de Cuidados Intensivos Polivalente (Ucip) em Portugal. MÉTODOS Análise retrospectiva dos dados referentes a DLT e DNR, recolhidos a partir de formulários previamente elaborados e complementados por consulta de processo clínico. RESULTADOS Um total de 1.602 doentes foi internado na Ucip entre 2011 e 2016. DNR foi documentada em 127 casos (7,9%). Doentes com DLT eram mais velhos e tinham um Simplified Acute Physiology Score II mais elevado. O diagnóstico mais frequente que precedeu essas decisões foi sepse (52,0%, n=66); A razão mais comum para limitar o tratamento foi mau prognóstico da doença aguda. Dos doentes nos quais a DNR foi implementada, 117 (92,1%) morreram na Ucip (40,1% do total de óbitos na Ucip) e a mortalidade hospitalar foi de 100%. Os intervenientes nessas decisões, bem como os tipos de tratamento retirados, não foram rotineiramente registrados. CONCLUSÃO As DLT e DNR foram relativamente comuns, em consonância com outros estudos do sul da Europa, mas atrás dos centros do norte da Europa e da América do Norte. Os doentes com essas limitações eram mais velhos e mais gravemente doentes. A documentação dessas decisões deve ser clara e detalhada, seja em formulários específicos, seja em registros clínicos informatizados. Há espaço para melhorias nessa área.

Minimal NMR distance information for rigidity of protein graphs.

Nuclear Magnetic Resonance (NMR) experiments provide distances between nearby atoms of a protein molecule. The corresponding structure determination problem is to determine the 3D protein structure by exploiting such distances. We present a new order on the atoms of the protein, based on information from the chemistry of proteins and NMR experiments, which allows us to formulate the problem as a combinatorial search. Additionally, this order tells us what kind of NMR distance information is crucial to understand the cardinality of the solution set of the problem and its computational complexity.

Efeitos de um programa de cuidados paliativos nas tendências de utilização da unidade de terapia intensiva e ordens de não reanimar durante hospitalizações terminais. Análise de séries temporais interrompidas / Effect of a palliative care program on trends in intensive care unit utilization and do-not-resuscitate orders during terminal hospitalizations. An interrupted time series analysis

RESUMO Objetivo: Avaliar os efeitos da implantação de um programa de cuidados paliativos no estabelecimento de ordens de não reanimar e na utilização da unidade de terapia intensiva em hospitalizações terminais. Método: Os dados de todos os pacientes que faleceram em um hospital terciário brasileiro, entre maio de 2014 e setembro de 2016, foram coletados de forma retrospectiva. Analisamos a frequência do estabelecimento de ordens de não reanimar e de admissões à unidade de terapia intensiva entre os casos de óbito hospitalar. Utilizou-se análise de séries temporais interrompidas para avaliar as diferenças, em termos de tendências de estabelecimento de ordens de não reanimar e de admissões à unidade de terapia intensiva antes (15 meses) e após (12 meses) a implantação do programa de cuidados paliativos. Resultados: Analisamos um total de 48.372 admissões ao hospital, dentre as quais 1.071 óbitos no hospital. Os óbitos foram precedidos de ordens de não reanimar em 276 (25,8%) casos e ocorreram admissões à unidade de terapia intensiva em 814 (76%) casos. O estabelecimento de ordens de não reanimar aumentou de 125 (20,4%) para 151 (33%) casos, na comparação entre os períodos antes e após a implantação do programa de cuidados paliativos (p < 0,001). Ocorreram admissões à unidade de terapia intensiva em 469 (76,5%) e 345 (75,3%) dos casos, respectivamente, nos períodos pré e após a implantação do programa de cuidados paliativos (p = 0,654). A análise de séries temporais confirmou tendência ao aumento do estabelecimento de ordens de não reanimar de 0,5% por mês antes da implantação para 2,9% ao mês após a implantação (p < 0,001), demonstrando-se tendência à diminuição de utilização da unidade de terapia intensiva, de uma tendência a aumento de 0,6% ao mês, antes da implantação do programa, para diminuição de -0,9% ao mês no período, após a implantação (p = 0,001). Conclusão: A implantação de um programa de cuidados paliativos se associou com tendência ao aumento no estabelecimento de ordens de não reanimar e à diminuição do uso da unidade de terapia intensiva durante hospitalizações terminais.

ABSTRACT Objective: To assess the effect of the implementation of a palliative care program on do-not-resuscitate orders and intensive care unit utilization during terminal hospitalizations. Methods: Data were retrospectively collected for all patients who died in a tertiary hospital in Brazil from May 2014 to September 2016. We analyzed the frequency of do-not-resuscitate orders and intensive care unit admissions among in-hospital deaths. Interrupted time series analyses were used to evaluate differences in trends of do-not-resuscitate orders and intensive care unit admissions before (17 months) and after (12 months) the implementation of a palliative care program. Results: We analyzed 48,372 hospital admissions and 1,071 in-hospital deaths. Deaths were preceded by do-not-resuscitate orders in 276 (25.8%) cases and admissions to the intensive care unit occurred in 814 (76%) cases. Do-not-resuscitate orders increased from 125 (20.4%) to 151 (33%) cases in the pre-implementation and post-implementation periods, respectively (p < 0.001). Intensive care unit admissions occurred in 469 (76.5%) and 345 (75.3%) cases in the pre-implementation and post-implementation periods, respectively (p = 0.654). Interrupted time series analyses confirmed a trend of increased do-not-resuscitate order registrations, from an increase of 0.5% per month pre-implementation to an increase of 2.9% per month post-implementation (p < 0.001), and demonstrated a trend of decreased intensive care unit utilization, from an increase of 0.6% per month pre-implementation to a decrease of -0.9% per month in the post-implementation period (p = 0.001). Conclusion: The implementation of a palliative care program was associated with a trend of increased registration of do-not-resuscitate orders and a trend of decreased intensive care unit utilization during terminal hospitalizations.

Frecuencia de órdenes de no reanimación en un hospital universitario de cuarto nivel de complejidad / Do-not-resuscitate orders frecuency in a fourth level university Hospital

Las órdenes de no reanimación (ONR) surgen luego de la introducción de la reanimación cardiopulmonar (RCP) en la práctica clínica como una alternativa para los pacientes que, por diferentes motivos, no eran candidatos para recibir este tipo de manejo médico. Con el tiempo se han incrementado las decisiones de no reanimar a los pacientes, posiblemente por el envejecimiento de la población, el aumento en la prevalencia de patologías oncológicas o una mayor sensibilización de los médicos en cuanto a los desenlaces de los pacientes que son llevados a una RCP. De acuerdo con lo anterior, se desarrolló este estudio con el objetivo de conocer y describir la frecuencia de las ONR y RCP en los pacientes que murieron en un hospital de cuarto nivel en la ciudad de Bogotá. Igualmente, se describieron las características demográficas de estos pacientes.

After the introduction of the cardiopulmonary resuscitation into clinical practice, non-resuscitation orders emerged as an alternative for those patients that, for several reasons, were not candidates to receive this type of medical treatment. Over time the non-resuscitation orders have increased in number, possibly due to the aging of the population, an increase in the prevalence of oncological pathologies or greater awareness of the physicians regarding the outcomes of the patients being carried to a CPR. According to the above, this study was developed with the objective of knowing and describing the frequency of ONR and CPR in patients who died in a 4th level hospital in the city of Bogotá. Likewise, the demographic characteristics of these patients were described.

Do not attempt resuscitation orders at the emergency department of a teaching hospital / Ordens de não ressuscitação no serviço de emergência de um hospital universitário

ABSTRACT Objective: To identify factors associated with not attempting resuscitation. Methods: A cross-sectional study conducted at the emergency department of a teaching hospital. The sample consisted of 285 patients; in that, 216 were submitted to cardiopulmonary resuscitation and 69 were not. The data were collected by means of the in-hospital Utstein Style. To compare resuscitation attempts with variables of interest we used the χ2 test, likelihood ratio, Fisher exact test, and analysis of variance (p<0.05). Results: No cardiopulmonary resuscitation was considered unjustifiable in 56.5% of cases; in that, 37.7% did not want resuscitation and 5.8% were found dead. Of all patients, 22.4% had suffered a previous cardiac arrest, 49.1% were independent for Activities of Daily Living, 89.8% had positive past medical/surgical history; 63.8% were conscious, 69.8% were breathing and 74.4% had a pulse upon admission. Most events (76.4%) happened at the hospital, the presumed cause was respiratory failure in 28.7% and, in 48.4%, electric activity without pulse was the initial rhythm. The most frequent cause of death was infection. The factors that influenced non-resuscitation were advanced age, history of neoplasm and the initial arrest rhythm was asystole. Conclusion: Advanced age, past history of neoplasia and asystole as initial rhythm were factors that significantly influenced the non-performance of resuscitation. Greater clarity when making the decision to resuscitate patients can positively affect the quality of life of survivors.

RESUMO Objetivo: Identificar fatores associados à não realização de ressuscitação. Métodos: Estudo transversal realizado no serviço de emergência de um hospital universitário. A amostra foi composta por 285 pacientes, dos quais 216 foram submetidos à ressuscitação cardiopulmonar, e 69 não tiveram esta conduta. Os dados foram coletados por meio do in-hospital Utstein Style. Para comparar as tentativas de ressuscitação e as variáveis de interesse, utilizaram-se o teste do χ2, a razão de verossimilhança, o teste exato de Fisher e a análise de variância (p<0,05). Resultados: A não ressuscitação foi considerada injustificável em 56,5% dos casos, sendo que 37,7% não queriam ressuscitação e 5,8% foram encontrados mortos. Do total de pacientes, 22,4% tiveram parada cardíaca prévia, 49,1% eram independentes para Atividades de Vida Diária, e 89,8% tinham alguma história pregressa; 63,8% estavam conscientes, 69,8% estavam respirando e 74,4% tinham pulso palpável à admissão. A maioria dos eventos (76,4%) ocorreu no hospital, e a causa presumida de parada foi insuficiência respiratória em 28,7% e, em 48,4%, o ritmo inicial foi atividade elétrica sem pulso. A causa mais frequente de morte foi infecção. Os fatores que influenciaram na não realização de ressuscitação foram idade avançada, história de neoplasia e assistolia como ritmo inicial de parada. Conclusão: Idade avançada, história de neoplasia e assistolia como ritmo inicial foram os fatores que influenciaram significativamente na não realização de ressuscitação. Maior clareza na decisão de reanimar pode afetar positivamente a qualidade de vida dos pacientes.

Percepção de pacientes oncológicos sobre terminalidade de vida / Perception of oncology patients on the terminality of life / Percepción de los pacientes oncológicos sobre la terminalidad de la vida

Resumo Objetivou-se analisar, por meio de pesquisa descritiva, a percepção de pacientes oncológicos diante da terminalidade da vida. Aplicou-se questionário para 100 pacientes oncológicos, dos quais 85% desconheciam testamento vital/diretivas antecipadas de vontade, 81% desconheciam cuidados paliativos e 70% desconheciam ordem de não reanimar. Após esclarecimento sobre os termos empregados, 62% concordariam em elaborar testamento vital/diretivas antecipadas de vontade, 82% concordariam em receber cuidados paliativos no domicílio e 64% em ser reanimados em qualquer situação, mas a maioria (73%) discordou da prática de distanásia. Apenas 11% referiram inadequação na forma de comunicação de seu diagnóstico pelo médico. A presença de metástases suscitou reflexão mais ampla sobre terminalidade da vida. Os resultados permitem inferir que é necessário incentivar a discussão sobre terminalidade da vida na população durante a assistência aos pacientes, bem como estimular o debate sobre o assunto durante a formação de profissionais de saúde.

Abstract With the aim of analysing the perception of cancer patients towards the end of life, a questionnaire was applied to 100 oncologic patients, of which 85% were unaware of living will/advance directives, 81% were unaware of the terms palliative care and 70% were unaware of order to not reanimate. After clarifying the meaning of the terms used, 62% agreed to make living will/advance directives, 82% to receive palliative care at home and 64% to be reanimated in any situation, but the majority (73%) disagreed with the practice of futility. Only 11% reported inadequacies in the communication of their diagnosis by the physician. The fact of having metastases elicited a broader reflection on the termination of life. The results allow to infer that it is necessary to encourage the discussion about termination of life to the population during patient care, as well to promote the respective training to health professionals since the undergraduate course.

Resumen Con el fin de analizar la percepción de los pacientes con cáncer frente al final de su vida, a través de una investigación descriptiva, se aplicó un cuestionario a 100 pacientes de cáncer, entre los cuales el 85% desconocía las directivas anticipadas de voluntad, el 81% desconocía los términos de cuidados paliativos y el 70% desconocía la orden de no reanimar. Después de la clarificación del significado de los términos utilizados, el 62% estaba de acuerdo para elaborar su testamento vital/directivas anticipadas de voluntad, el 82% para recibir los cuidados paliativos en el hogar y el 64% para ser restablecido en cualquier situación, pero la mayoría (73%) no estuvo de acuerdo con la distanasia. Tan sólo el 11% consideró inadecuada la comunicación del diagnóstico por el médico. El hecho de portar metástasis amplió la reflexión sobre el final de la vida. Los resultados muestran que es necesario fomentar la discusión del final de la vida en la población durante la atención al paciente, y promover la respectiva formación a los profesionales de la salud desde el pregrado.

Ordem de não reanimar sob a perspectiva depacientes oncológicos e seus familiares / Do not resuscitate orders from the perspective of oncology patients and their relatives

O presente estudo objetivou verificar a perspectiva dos pacientes oncológicos e familiares em relação à Ordem deNão Reanimar (ONR). Foram entrevistados 104 pacientes oncológicos e 100 familiares que frequentavam o serviço deoncologia do Hospital Universitário Santa Terezinha, Joaçaba, Santa Catarina, Brasil, no ano de 2014. Os termos ONReram desconhecidos por 81,73% dos pacientes e por 82% dos familiares. Após esclarecimento do significado, 65,4%dos pacientes e 67% dos familiares mostraram-se favoráveis à ONR em caso de parada cardiorrespiratória de pacienteem fase final de doença terminal. A decisão compartilhada entre pacientes, familiares e médico obteve a preferência de58,65% dos pacientes e de 73% dos familiares, por iniciativa do médico que acompanha o tratamento, segundo 60,58%dos pacientes e 72% dos familiares. A realização de sua própria ONR foi considerada importante por 63,47% dospacientes e 68,63% dos familiares e a implantação da Ordem de não reanimar no Brasil por 75% dos pacientes e 74%dos familiares. Concluiu-se que a maioria dos pacientes e familiares desconhecia os termos ordem de não reanimar, masera favorável à implantação do procedimento no Brasil, à realização pessoal por meio de decisão compartilhada e quea abordagem ocorresse durante as consultas médicas. Os resultados deste estudo permitem inferir a necessidade de seampliar a discussão sobre a Ordem de Não Reanimar, no âmbito ético e social, com a finalidade de se emitir orientaçõespara assegurar a autonomia dos pacientes que se encontram na terminalidade da vida

This study aims to determine the perspective of oncological patients and their families in relation to the Do Not ResuscitateOrder (DNR). A questionnaire was applied to 104 oncological patients and 100 relatives, who were attended to by theoncology service of Hospital Universitário Santa Terezinha, Joaçaba, Santa Catarina, Brazil in 2014. The term DNR wasunknown by 81.73% of the patients and by 82% of the relatives. After clarifying its meaning, 65.4% of patients and 67%of the relatives were favorable towards DNR in the event of cardiorespiratory failure of the patient, in the final phase ofthe terminal disease. A shared decision between the patients, their relatives, and the doctor was preferred by 58.65%of patients and 73% of the relatives; a decision prompted by the initiative of the doctor accompanying the treatmentwas preferred by 60.58% of the patients and 72% of the relatives. The execution of the DNR by the patient him/herselfwas considered important by 63.47% of the patients and 68.63% of the relatives, and the introduction of the DNR inBrazil was considered important by 75% of the patients and 74% of the relatives. It is concluded that the majority ofthe patients and relatives did not know the term "Do Not Resuscitate Order", but were favorable to the introduction ofthe procedure in Brazil, the personal realization through the shared decision, and that the approach would occur duringmedical visits. The results of this study enable us to infer the need to broaden the discussion on DNR, in the ethical socialscope, in order to issue guidance to ensure the autonomy of patients who are in the terminal phases of life

Natural vegetation cover in the landscape and edge effects: differential responses of insect orders in a fragmented forest.

Human activities have led to global simplification of ecosystems, among which Neotropical dry forests are some of the most threatened. Habitat loss as well as edge effects may affect insect communities. Here, we analyzed insects sampled with pan traps in 9 landscapes (at 5 scales, in 100-500 m diameter circles) comprising cultivated fields and Chaco Serrano forests, at overall community and taxonomic order level. In total 7043 specimens and 456 species of hexapods were captured, with abundance and richness being directly related to forest cover at 500 m and higher at edges in comparison with forest interior. Community composition also varied with forest cover and edge/interior location. Different responses were detected among the 8 dominant orders. Collembola, Hemiptera, and Orthoptera richness and/or abundance were positively related to forest cover at the larger scale, while Thysanoptera abundance increased with forest cover only at the edge. Hymenoptera abundance and richness were negatively related to forest cover at 100 m. Coleoptera, Diptera, and Hymenoptera were more diverse and abundant at the forest edge. The generally negative influence of forest loss on insect communities could have functional consequences for both natural and cultivated systems, and highlights the relevance of forest conservation. Higher diversity at the edges could result from the simultaneous presence of forest and matrix species, although "resource mapping" might be involved for orders that were richer and more abundant at edges. Adjacent crops could benefit from forest proximity since natural enemies and pollinators are well represented in the orders showing positive edge effects.

Opinions of Brazilian resuscitation instructors regarding resuscitation in the delivery room of extremely preterm newborns / Opiniões dos instrutores de reanimação brasileiros quanto à reanimação em sala de parto de em recém-nascidos pré-termo extremos

Abstract Objective: To describe the opinions of pediatricians who teach resuscitation in Brazil on initiating and limiting the delivery room resuscitation of extremely preterm infants. Method: Cross-sectional study with electronic questionnaire (Dec/2011-Sep/2013) sent to pediatricians who are instructors of the Neonatal Resuscitation Program of the Brazilian Society of Pediatrics, containing three hypothetical clinical cases: (1) decision to start the delivery room resuscitation; (2) limitation of neonatal intensive care after delivery room resuscitation; (3) limitation of advanced resuscitation in the delivery room. For each case, it was requested that the instructor indicate the best management for each gestational age between 23 and 26 weeks. A descriptive analysis was performed. Results: 560 (82%) instructors agreed to participate. Only 9% of the instructors reported the existence of written guidelines at their hospital regarding limitations of delivery room resuscitation. At 23 weeks, 50% of the instructors would initiate delivery room resuscitation procedures. At 26 weeks, 2% would decide based on birth weight and/or presence of fused eyelids. Among the participants, 38% would re-evaluate their delivery room decision and limit the care for 23-week neonates in the neonatal intensive care unit. As for advanced resuscitation, 45% and 4% of the respondents, at 23 and 26 weeks, respectively, would not apply chest compressions and/or medications. Conclusion: Difficulty can be observed regarding the decision to not resuscitate a preterm infant with 23 weeks of gestational age. At the same time, a small percentage of pediatricians would not resuscitate neonates of unquestionable viability at 26 weeks of gestational age in the delivery room.

Resumo Objetivo: Descrever opiniões dos pediatras que ensinam reanimação no Brasil a respeito de iniciar e limitar a reanimação em sala de parto de neonatos pré-termo extremos. Método: Estudo transversal com questionário eletrônico (dez/11-set/13) enviado aos instrutores do Programa de Reanimação Neonatal da Sociedade Brasileira de Pediatria com três casos clínicos hipotéticos: 1) decisão de iniciar ou não a reanimação; 2) limitação ou não dos cuidados intensivos após a reanimação em sala de parto; 3) limitação ou não da reanimação avançada em sala de parto. Para cada caso foi solicitada a indicação da conduta para cada idade gestacional entre 23-26 semanas. A análise foi descritiva por meio da frequência das respostas. Resultados: Consentiram em participar 560 (82%) instrutores. Apenas 9% afirmaram existir em seu hospital norma escrita sobre quando não iniciar a reanimação em sala de parto. Com 23 semanas, 50% dos instrutores fariam a reanimação em sala de parto e com 26 semanas 2% baseariam sua decisão no peso ao nascer e/ou na abertura da fenda palpebral. Dos entrevistados, 38% reavaliariam sua decisão e limitariam o cuidado na UTI a medidas de conforto para nascidos de 23 semanas reanimados na sala de parto. Quanto aos procedimentos de reanimação avançada, 45% e 4% com 23 e 26 semanas, respectivamente, não indicariam tais manobras. Conclusão: Observa-se dificuldade na opção de não reanimar neonatos com 23 semanas de gestação e, ao mesmo tempo, um pequeno percentual de pediatras não reanima, na sala de parto, neonatos cuja viabilidade não é questionada (26 semanas).

A clausura enferma: petições para a saída do Convento da Ajuda no Rio de Janeiro para tratamento de doenças contagiosas, c.1750-1780 / Disease in the cloisters: requests to leave Convento da Ajuda, Rio de Janeiro, for the treatment of contagious diseases, c.1750-1780

O artigo discute os pedidos de freiras do Convento da Ajuda para deixar a clausura a fim de curar doenças contagiosas. O padecimento dessas doenças era considerado uma das poucas exceções para permitir a saída das freiras. As ordens femininas guardavam estritamente a clausura, condição necessária para manter o recato de virgens consagradas a Cristo. A documentação contém detalhes sobre as causas e as formas de transmissão das doenças, bem como sobre os tipos de tratamento para combatê-las. Por fim, os processos esclarecem os procedimentos adotados fora da clausura para as freiras não colocarem em risco o recolhimento e a honra, quando iam buscar em locais distantes o tratamento adequado para aquelas doenças.(AU)

This article discusses the requests submitted by nuns from Convento da Ajuda (Ajuda Convent) to leave their life of enclosure to receive treatment for contagious diseases. Disease was one of the few cases in which nuns were granted permission to leave. The female orders were strictly cloistered in order to preserve their purity as virgins consecrated to Christ. Extant documents detail the causes of the diseases, the ways they were transmitted, and the treatments used to fight them. These processes shed light on the procedures adopted outside the cloisters so that the nuns did not jeopardize their reclusion and honor when they went to distant places in search of treatment.(AU)

Percepção de profissionais de saúde sobre o processo de tomada de decisão na assistência a pacientes pediátricos / Health professionals' perceptions about the decision-making process in the care of pediatric patients

RESUMO Objetivo: Avaliar as percepções de médicos, enfermeiros e técnicos de enfermagem sobre sua participação no processo de tomada de decisão de limitação de suporte de vida, em pacientes pediátricos terminais, comparando por categoria profissional. Métodos: Estudo transversal realizado em unidade de terapia intensiva pediátrica de hospital público universitário, terciário, com a participação de médicos, enfermeiros e técnicos de enfermagem. Foi usada a Escala de Voz da MacArthur Admission Experience Survey para avaliar e quantificar a percepção dos profissionais que assistiram 17 pacientes pediátricos em limitação de suporte de vida, nas primeiras 24 horas após o desfecho de cada paciente. Todos os profissionais que atuavam na unidade (n=117), potencialmente elegíveis para a pesquisa, receberam o Termo de Consentimento Livre e Esclarecido previamente à ocorrência dos casos. Resultados: Participaram 25/40 (62,5%) médicos, 10/17 (58,8%) enfermeiros e 41/60 (68,3%) técnicos de enfermagem, representando 65% dos profissionais elegíveis. A taxa de devolução dos questionários pelos médicos foi maior que a dos técnicos (p = 0,0258). Houve registro de percepção de falta de voz nas três categorias profissionais, em taxas variáveis, porém menos percebida pelos médicos do que pelos enfermeiros e técnicos (p < 0,00001); entre estes últimos, não houve diferença (p = 0,7016). Nas três categorias profissionais, foram assinalados os três itens que compõem a subescala. Em duas das três afirmativas, houve diferença significativa entre médicos e enfermeiros (p = 0,004), e entre médicos e técnicos (p = 0,001). Em uma das afirmativas, não houve diferença entre as três categorias profissionais. Conclusão: Houve percepção de falta de voz no processo de tomada de decisão, em taxas variáveis, nas três categorias de profissionais que assistiram pacientes pediátricos terminais em limitação de suporte de vida, sendo os médicos os que expressaram menor percepção de coerção.

ABSTRACT Objective: To evaluate the perceptions of physicians, nurses and nursing technicians of their participation in the decision-making process surrounding life support limitation in terminally ill pediatric patients, with comparisons by professional category. Methods: A cross-sectional study was conducted in the pediatric intensive care unit of a tertiary public university hospital with the participation of physicians, nurses and nursing technicians. The MacArthur Admission Experience Survey Voice Scale was used to assess and quantify the perceptions of professionals who assisted 17 pediatric patients with life support limitation within 24 hours after the outcome of each patient was determined. All professionals working in the unit (n = 117) who were potentially eligible for the study received a free and informed consent form prior to the occurrence of the cases studied. Results: Study participants included 25/40 (62.5%) physicians, 10/17 (58.8%) nurses and 41/60 (68.3%) nursing technicians, representing 65% of the eligible professionals identified. The questionnaire return rate was higher for physicians than technicians (p = 0.0258). A perceived lack of voice was reported in all three professional categories at varying rates that were lower for physicians than for nurses and nursing technicians (p < 0.00001); there was no difference between the latter (p = 0.7016). In the three professional categories studied, three subscale items were reported. For two of the three statements, there were significant differences between physicians and nurses (p = 0.004) and between physicians and nursing technicians (p = 0.001). For one of the statements, there was no difference among the three professional categories. Conclusion: Respondents perceived a lack of voice in the decision-making process at varying rates across the three categories of studied professionals who assisted terminally ill pediatric patients with life support limitation, with physicians expressing lowered rates of perceived coercion.
