Depressão pós-parto: detecção precoce e fatores associados
A depressão pós-parto (DPP) é um transtorno de humor que se manifesta em mulheres duas semanas após o parto, caracteriza-se por humor deprimido ou perda de interesse e prazer por quase todas as atividades. Assim, com o intuito de realizar uma revisão bibliográfica foram pesquisados 5 artigos que abordam o tema DPP, através da plataforma Google Acadêmico, com o objetivo de apresentar os fatores relacionados e os métodos de prevenção da Depressão Pós-parto. A partir deste estudo foi identificado que o principal agente causador de DPP foi a gravidez não planejada, mas existem outros fatores desencadeantes assim como fatores preventivos de fundamental importância como a orientação, acompanhamento e pré-natal diagnóstico. Dessa forma o presente artigo tem a finalidade de prestar informações e conhecimentos sobre a DPP, para um possível pré-diagnóstico e prevenção da mesma
Data standardization of plant–pollinator interactions
Background: Animal pollination is an important ecosystem function and service, ensuring both the integrity of natural systems
and human well-being. Although many knowledge shortfalls remain, some high-quality data sets on biological interactions are now
available. The development and adoption of standards for biodiversity data and metadata has promoted great advances in biological
data sharing and aggregation, supporting large-scale studies and science-based public policies. However, these standards are currently
not suitable to fully support interaction data sharing.
Results: Here we present a vocabulary of terms and a data model for sharing plant–pollinator interactions data based on the Darwin
Core standard. The vocabulary introduces 48 new terms targeting several aspects of plant–pollinator interactions and can be used to
capture information from different approaches and scales. Additionally, we provide solutions for data serialization using RDF, XML,
and DwC-Archives and recommendations of existing controlled vocabularies for some of the terms. Our contribution supports open
access to standardized data on plant–pollinator interactions.
Conclusions: The adoption of the vocabulary would facilitate data sharing to support studies ranging from the spatial and temporal
distribution of interactions to the taxonomic, phenological, functional, and phylogenetic aspects of plant–pollinator interactions. We
expect to fill data and knowledge gaps, thus further enabling scientific research on the ecology and evolution of plant–pollinator
communities, biodiversity conservation, ecosystem services, and the development of public policies. The proposed data model is
flexible and can be adapted for sharing other types of interactions data by developing discipline-specific vocabularies of termsinfo:eu-repo/semantics/publishedVersio
Convalescent plasma for COVID-19 in hospitalised patients : an open-label, randomised clinical trial
Background: The effects of convalescent plasma (CP) therapy in hospitalised patients with coronavirus disease 2019 (COVID-19) remain uncertain. This study investigates the effect of CP on clinical improvement in these patients. Methods: This is an investigator-initiated, randomised, parallel arm, open-label, superiority clinical trial. Patients were randomly (1:1) assigned to two infusions of CP plus standard of care (SOC) or SOC alone. The primary outcome was the proportion of patients with clinical improvement 28 days after enrolment. Results: A total of 160 (80 in each arm) patients (66.3% critically ill, 33.7% severely ill) completed the trial. The median (interquartile range (IQR)) age was 60.5 (48–68) years; 58.1% were male and the median (IQR) time from symptom onset to randomisation was 10 (8–12) days. Neutralising antibody titres >1:80 were present in 133 (83.1%) patients at baseline. The proportion of patients with clinical improvement on day 28 was 61.3% in the CP+SOC group and 65.0% in the SOC group (difference −3.7%, 95% CI −18.8–11.3%). The results were similar in the severe and critically ill subgroups. There was no significant difference between CP+SOC and SOC groups in pre-specified secondary outcomes, including 28-day mortality, days alive and free of respiratory support and duration of invasive ventilatory support. Inflammatory and other laboratory marker values on days 3, 7 and 14 were similar between groups. Conclusions: CP+SOC did not result in a higher proportion of clinical improvement on day 28 in hospitalised patients with COVID-19 compared to SOC alone
O uso do plasma convalescente para tratamento de pacientes graves com covid-19 : avaliação das características dos doadores
Cardiomiopatia de Takotsubo: uma breve revisão sistemática: Takotsubo Cardiomiopathy: a brief systematic review
A cardiomiopatia de Takotsubo é uma nova cardiomiopatia que foi noticiada pela primeira vez em 2001. A doença é definida por disfunção reversível do ventrículo esquerdo e manifesta-se normalmente como uma síndrome coronária aguda. Este estudo teve como objetivo discutir as principais características da cardiomiopatia takotsubo. Para isso, foi desenvolvida uma revisão sistemática de literatura, recorrendo-se às bases de dados Scielo, Medline e Lilacs, selecionando-se estudos publicados nos últimos 5 anos. A partir da análise e interpretação dos dados das fontes foi possível concluir que a cardiomiopatia de takotsubo é desencadeada pelo estresse físico e é vista como uma complicação para outras doenças não cardíacas, se apresentando geralmente em mulheres pós-menopausa, acima dos 70 anos de idade. Manifesta-se com início súbito de dor torácica e dispneia, após um evento emocional estressante que precede o início dos sintomas. Com principais consequências, tem-se choque cardiogênico, obstrução da via de saída do ventrículo esquerdo, trombo da parede ventricular esquerda, arritmias ventriculares, ruptura da parede ventricular e paragem cardíaca, registrando-se alguns casos de morte súbita

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world
Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic.
Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality.
Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States.
Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis.
Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
Physicochemical and toxicological properties of novel amino acid-based amphiphiles and their spontaneously formed catanionic vesicles
The design of efficient liposomal systems for drug delivery is of considerable biomedical interest. In this context, vesicles prepared from cationic/anionic surfactants may offer several advantages, mainly due to their spontaneity in formation and long-term stability. There is also an impending need to produce less toxic, more biocompatible amphiphiles, while maintaining the desirable aggregation properties. In this work, we present data for acute toxicity to Daphnia magna (IC(50)), and potential ocular irritation (HC(50)) for some newly prepared ionic surfactants with dodecyl chains, derived from the amino acids tyrosine (Tyr), serine (Set), hydroxyproline (Hyp) and lysine (Lys). The micellization behavior of the compounds, evaluated from surface tension measurements, is presented and compared to more conventional ionic amphiphiles. Two types of spontaneouly formed catanionic vesicles, composed either by a dodecyltrimethylammonium bromide (DTAB)/Lys-derivative and or Ser-/Lys-derivative mixture, have also been tested for their ecotoxicity and hemolytic potential. All the micelle-forming surfactants as well as the vesicle-containing mixtures are found to have lower ecotoxicity than the reference surfactant DTAB. Moreover, the results from hemolysis and hemoglobin denaturation tests show that the Tyr- and Lys-derivatives are moderately irritant, whereas the Hyp- and Ser-ones are just slightly irritant. Even more significantly, the vesicle-containing mixtures exhibit lower hemolytic activity than the neat surfactants, a positive result for their potential use in liposomal formulations
