    O advento da pandemia pela Covid-19 e seus desdobramentos nos processos de saúde-doença-cuidado trouxeram inúmeros desafios para a prática de profissionais da saúde, entre eles, as experiências e manejo do luto. Este trabalho objetiva discutir os desafios que se apresentam aos profissionais de saúde ao lidar com o luto no hospital em tempos de pandemia. A partir das contribuições da Teoria Psicanalítica de Freud e do luto como uma Transição Psicossocial proposto por Parkes, reflete-se sobre o cotidiano de trabalho de profissionais de saúde ao lidar com pacientes morrendo e suas famílias. Acompanhar a morte e sofrimento de alguém não é uma tarefa fácil, tampouco leve, mas reconhecê-la em sua dificuldade e singularidade e compartilhá-la com pares e equipe pode tornar a jornada menos solitária e sofrida. Nesse sentido, acredita-se que o fortalecimento das relações interprofissionais, bem como de espaços de trocas e apoio mútuo, pode se mostrar fundamental frente à experiência de luto.

    Abordagens clínicas da doença do refluxo gastroesofágico no âmbito atual: uma revisão de literatura

    A Doença do Refluxo Gastroesofágico (DRGE) pode ser definida como uma condição na qual o retorno do conteúdo gástrico para o esôfago desencadeia sintomas incômodos e/ou complicações (BARREIRO,B.A e et al., 2023). Ademais, a DRGE é uma das afecções digestivas mais incidentes, cerca de 20% dos adultos nos países ocidentais e aproximadamente 5% dos asiáticos são portadores da doença e a prevalência anual dos sintomas vem aumentando por volta de 4% (BARREIRO, B.A et al., 2023). Logo, este artigo tem como objetivo analisar as abordagens clinicas da doenca do refluxo gastroesofágico no âmbito atual. Dessa forma, este estudo configura-se como uma revisão integrativa realizada por meio do levantamento bibliográfico nos diretórios: Google Scholare Scientific Eletronic LibraryOn-line (SciELO). Desta busca, foram selecionados artigos entre os anos 2021 e 2023, posteriormente submetidos aos critérios de seleção. A doença do refluxo gastroesofágico está associada a uma probabilidade 5 a 7 vezes maior de desenvolver adenocarcinoma esofágico e 60% dos pacientes com câncer relatam história de DRGE. O esôfago de Barrett é uma adaptação metaplásica das células esofágicas em que a mucosa do tipo intestinal substitui a mucosa escamosa normal. Cerca de 15% dos pacientes com DRGE desenvolvem esôfago de Barret. Contínuo a isso, os tratamento mais comuns utilizados na pratica clinica são medidas não farmacológicas como dieta, sono e fitoterapia e farmacológicas como inibidores da bomba de prótons (IBPS), bloqueadores de H2 e procinéticos. Dessa forma, conclui-se que, embora a supressão ácida seja bem-sucedida no tratamento da DRGE, não parece haver uma relação clara entre a gravidade da DRGE e os níveis elevados de ácido gástrico. Ademais, a junção do tratamento farmacológico com o não farmacológico se mostrou superior a abordagem destes de forma isolada

    A plasmid DNA-launched SARS-CoV-2 reverse genetics system and coronavirus toolkit for COVID-19 research

    The recent emergence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the underlying cause of Coronavirus Disease 2019 (COVID-19), has led to a worldwide pandemic causing substantial morbidity, mortality, and economic devastation. In response, many laboratories have redirected attention to SARS-CoV-2, meaning there is an urgent need for tools that can be used in laboratories unaccustomed to working with coronaviruses. Here we report a range of tools for SARS-CoV-2 research. First, we describe a facile single plasmid SARS-CoV-2 reverse genetics system that is simple to genetically manipulate and can be used to rescue infectious virus through transient transfection (without in vitro transcription or additional expression plasmids). The rescue system is accompanied by our panel of SARS-CoV-2 antibodies (against nearly every viral protein), SARS-CoV-2 clinical isolates, and SARS-CoV-2 permissive cell lines, which are all openly available to the scientific community. Using these tools, we demonstrate here that the controversial ORF10 protein is expressed in infected cells. Furthermore, we show that the promising repurposed antiviral activity of apilimod is dependent on TMPRSS2 expression. Altogether, our SARS-CoV-2 toolkit, which can be directly accessed via our website at https://mrcppu-covid.bio/, constitutes a resource with considerable potential to advance COVID-19 vaccine design, drug testing, and discovery science

    Síndrome de Chiari e Hidrossiringomielia com comprometimento neurológico: um relato de caso

    Get PDF
    A Malformação de Chiari (MC) pertence a um amplo grupo de raras deformidades estruturais da junção craniocerebelomedular. O tipo I da doença caracteriza-se pela herniação tonsilar ou amigdaliana cerebelar devido à anomalia da base do crânio e da parte superior da coluna cervical, além de a porção medial do lobo inferior do cerebelo pelo canal cervical também se protuberar através do forame magno, impedindo que o líquor flua normalmente através do canal. A real prevalência da doença é desconhecida, pois muitos pacientes com herniação cerebelar são assintomáticos e o problema agrava-se na fase adulta, com queixas de cefaleia intensa e, por vezes, parestesia. O objetivo deste estudo é relatar um caso de síndrome de Chiari (SC) em uma paciente de 53 anos, ao abordar sua apresentação clínica, diagnóstico e tratamento. Paciente do sexo feminino, 53 anos, foi admitida em um hospital da rede pública de referência se queixando de cefaleia occipital intensa e cervicalgia com irradiação da dor para os membros superiores, acompanhada de parestesia nos quatro segmentos. Relatou já sentir dor há 2 anos, mas apresentou piora do quadro clínico há 8 meses. Foi, também, observada incontinência urinária devido à dissinergia detrusora-esfincteriana por provável bexiga neurogênica. Foi, então, realizado exame de imagem de ressonância magnética (RNM) do crânio e da coluna cervical, com obtenção de sequências ponderadas em T1, T2 e STIR, nos planos sagital e transverso com contraste, o qual evidenciou leve alargamento medular, além de sinais de hidrossiringomielia difusa, com hipossinal na sequência T2 intramedular na altura de D1-D2 (coluna dorsal). Foi notada discreta herniação das tonsilas cerebelares junta ao forame magno, típica da SC, sendo, por fim, confirmado o diagnóstico. A paciente, no entanto, não apresentava hidrocefalia, mesmo com a interrupção do fluxo do líquido cefalorraquidiano (LCR) para o canal vertebral. Ela encaixou- se nos parâmetros de indicação cirúrgica, sendo realizada craniotomia occipital, com acesso ao plexo coroide do quarto ventrículo do tronco encefálico com o intuito de elevar as tonsilas cerebelares baixas, herniadas no canal espinhal cervical e bloqueando o fluxo do LCR. Após a descompressão craniocervical, o curso do líquor foi restaurado e a paciente foi, por fim, encaminhada à sala de recuperação pós-operatória. A SC é uma rara doença que apresenta quadro clínico e alterações radiológicas complexas e extensas e, por vezes, o diagnóstico é retardado devido à inespecificidade dos sintomas confundidos com cervicalgias e cefaleias comuns. A hipótese diagnóstica deve ser embasada nas queixas do paciente, na anamnese minuciosa, exame clínico e nos exames de imagens, sendo a prevalência desta patologia de difícil definição e com faixas etárias distintas

    CropPol: a dynamic, open and global database on crop pollination

    Get PDF
    Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to crop yield, as well as to anticipate changes in this service, develop predictions, and inform management actions. Here, we present CropPol, a dynamic, open and global database on crop pollination. It contains measurements recorded from 202 crop studies, covering 3,394 field observations, 2,552 yield measurements (i.e. berry weight, number of fruits and kg per hectare, among others), and 47,752 insect records from 48 commercial crops distributed around the globe. CropPol comprises 32 of the 87 leading global crops and commodities that are pollinator dependent. Malus domestica is the most represented crop (32 studies), followed by Brassica napus (22 studies), Vaccinium corymbosum (13 studies), and Citrullus lanatus (12 studies). The most abundant pollinator guilds recorded are honey bees (34.22% counts), bumblebees (19.19%), flies other than Syrphidae and Bombyliidae (13.18%), other wild bees (13.13%), beetles (10.97%), Syrphidae (4.87%), and Bombyliidae (0.05%). Locations comprise 34 countries distributed among Europe (76 studies), Northern America (60), Latin America and the Caribbean (29), Asia (20), Oceania (10), and Africa (7). Sampling spans three decades and is concentrated on 2001-05 (21 studies), 2006-10 (40), 2011-15 (88), and 2016-20 (50). This is the most comprehensive open global data set on measurements of crop flower visitors, crop pollinators and pollination to date, and we encourage researchers to add more datasets to this database in the future.

    The impact of surgical delay on resectability of colorectal cancer: An international prospective cohort study

    Get PDF
    AIM: The SARS-CoV-2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non-delayed surgery. METHODS: This was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January-April 2020). Surgical delay was defined as an operation taking place more than 4 weeks after treatment decision, in a patient who did not receive neoadjuvant therapy. A subgroup analysis explored the effects of delay in elective patients only. The impact of longer delays was explored in a sensitivity analysis. The primary outcome was complete resection, defined as curative resection with an R0 margin. RESULTS: Overall, 5453 patients from 304 hospitals in 47 countries were included, of whom 6.6% (358/5453) did not receive their planned operation. Of the 4304 operated patients without neoadjuvant therapy, 40.5% (1744/4304) were delayed beyond 4 weeks. Delayed patients were more likely to be older, men, more comorbid, have higher body mass index and have rectal cancer and early stage disease. Delayed patients had higher unadjusted rates of complete resection (93.7% vs. 91.9%, P = 0.032) and lower rates of emergency surgery (4.5% vs. 22.5%, P < 0.001). After adjustment, delay was not associated with a lower rate of complete resection (OR 1.18, 95% CI 0.90-1.55, P = 0.224), which was consistent in elective patients only (OR 0.94, 95% CI 0.69-1.27, P = 0.672). Longer delays were not associated with poorer outcomes. CONCLUSION: One in 15 colorectal cancer patients did not receive their planned operation during the first wave of COVID-19. Surgical delay did not appear to compromise resectability, raising the hypothesis that any reduction in long-term survival attributable to delays is likely to be due to micro-metastatic disease

    Global, regional, and national age-sex-specific mortality for 282 causes of death in 195 countries and territories, 1980-2017 : a systematic analysis for the Global Burden of Disease Study 2017

    Background Global development goals increasingly rely on country-specific estimates for benchmarking a nation's progress. To meet this need, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 estimated global, regional, national, and, for selected locations, subnational cause-specific mortality beginning in the year 1980. Here we report an update to that study, making use of newly available data and improved methods. GBD 2017 provides a comprehensive assessment of cause-specific mortality for 282 causes in 195 countries and territories from 1980 to 2017. Methods The causes of death database is composed of vital registration (VR), verbal autopsy (VA), registry, survey, police, and surveillance data. GBD 2017 added ten VA studies, 127 country-years of VR data, 502 cancer-registry country-years, and an additional surveillance country-year. Expansions of the GBD cause of death hierarchy resulted in 18 additional causes estimated for GBD 2017. Newly available data led to subnational estimates for five additional countries Ethiopia, Iran, New Zealand, Norway, and Russia. Deaths assigned International Classification of Diseases (ICD) codes for non-specific, implausible, or intermediate causes of death were reassigned to underlying causes by redistribution algorithms that were incorporated into uncertainty estimation. We used statistical modelling tools developed for GBD, including the Cause of Death Ensemble model (CODErn), to generate cause fractions and cause specific death rates for each location, year, age, and sex. Instead of using UN estimates as in previous versions, GBD 2017 independently estimated population size and fertility rate for all locations. Years of life lost (YLLs) were then calculated as the sum of each death multiplied by the standard life expectancy at each age. All rates reported here are age-standardised. Findings At the broadest grouping of causes of death (Level 1), non-communicable diseases (NC Ds) comprised the greatest fraction of deaths, contributing to 73.4% (95% uncertainty interval [UI] 72.5-74.1) of total deaths in 2017, while communicable, maternal, neonatal, and nutritional (CMNN) causes accounted for 186% (17.9-19.6), and injuries 8.0% (7.7-8.2). Total numbers of deaths from NCD causes increased from 2007 to 2017 by 22.7% (21.5-23.9), representing an additional 7.61 million (7. 20-8.01) deaths estimated in 2017 versus 2007. The death rate from NCDs decreased globally by 7.9% (7.08.8). The number of deaths for CMNN causes decreased by 222% (20.0-24.0) and the death rate by 31.8% (30.1-33.3). Total deaths from injuries increased by 2.3% (0-5-4-0) between 2007 and 2017, and the death rate from injuries decreased by 13.7% (12.2-15.1) to 57.9 deaths (55.9-59.2) per 100 000 in 2017. Deaths from substance use disorders also increased, rising from 284 000 deaths (268 000-289 000) globally in 2007 to 352 000 (334 000-363 000) in 2017. Between 2007 and 2017, total deaths from conflict and terrorism increased by 118.0% (88.8-148.6). A greater reduction in total deaths and death rates was observed for some CMNN causes among children younger than 5 years than for older adults, such as a 36.4% (32.2-40.6) reduction in deaths from lower respiratory infections for children younger than 5 years compared with a 33.6% (31.2-36.1) increase in adults older than 70 years. Globally, the number of deaths was greater for men than for women at most ages in 2017, except at ages older than 85 years. Trends in global YLLs reflect an epidemiological transition, with decreases in total YLLs from enteric infections, respirator}, infections and tuberculosis, and maternal and neonatal disorders between 1990 and 2017; these were generally greater in magnitude at the lowest levels of the Socio-demographic Index (SDI). At the same time, there were large increases in YLLs from neoplasms and cardiovascular diseases. YLL rates decreased across the five leading Level 2 causes in all SDI quintiles. The leading causes of YLLs in 1990 neonatal disorders, lower respiratory infections, and diarrhoeal diseases were ranked second, fourth, and fifth, in 2017. Meanwhile, estimated YLLs increased for ischaemic heart disease (ranked first in 2017) and stroke (ranked third), even though YLL rates decreased. Population growth contributed to increased total deaths across the 20 leading Level 2 causes of mortality between 2007 and 2017. Decreases in the cause-specific mortality rate reduced the effect of population growth for all but three causes: substance use disorders, neurological disorders, and skin and subcutaneous diseases. Interpretation Improvements in global health have been unevenly distributed among populations. Deaths due to injuries, substance use disorders, armed conflict and terrorism, neoplasms, and cardiovascular disease are expanding threats to global health. For causes of death such as lower respiratory and enteric infections, more rapid progress occurred for children than for the oldest adults, and there is continuing disparity in mortality rates by sex across age groups. Reductions in the death rate of some common diseases are themselves slowing or have ceased, primarily for NCDs, and the death rate for selected causes has increased in the past decade.
