    Ovarian borderline tumors (OBTs) are frequently diagnosed in women of reproductive age. There is no consensus about their management, and it sometimes represents a dilemma aboutwhat should be done: fertility sparing surgery or a hysterectomy with salpingo-oophorectomy? Case: A 32-year-old nulligravida, diagnosed with a right ovarian borderline tumor is presented. She underwent pelvic washings, right salpingo-oophorectomy, appendectomy, and omental and peritoneal biopsies (laparotomic approach). Macroscopically, the left ovary was normal and subsequent exploration for staging was also normal, including the lymph nodes. Intraoperatively, frozen section examination was unclear, suggesting an OBT. Results: The final histopathologic diagnosis was ovarian borderline tumor, stage IIC (International Federation of Gynecology and Obstetrics [FIGO] staging). The patient expressed a desire to preserve her fertility. Thirty-six months postsurgery, she became pregnant spontaneously and delivered a healthy newborn at term. Conclusions: Conservative surgery can be performed in young patients treated for an OBT, provided they are closely followed up and that this surgery is performed after careful consideration and informed consent. It is, however, controversial with respect to performing hysterectomy and salpingo-oopherectomy upon the patient’s completion of childbearing

    Litteras arena conspergere. Uncovering blotting sands on the Portuguese Inquisition documents

    Get PDF
    Historical and archival research focused on the Portuguese Inquisition documents (1551–1800) uncovered the use of arena known as blotting sands, a writing accessory used to hasten ink drying. We present in this work the first systematic study combining image analysis, SEM/EDS and µ-Raman techniques, statistics and chemometrics to characterise the blotting sands used by the Portuguese Inquisition and hypothesise their provenance. Iron-titanium and iron oxide minerals categorised as texturally mature sands are the dominant species, consistent with sediment extraction from fluvial or beach contexts and later processed. Chemometrics unveiled time period trends by clustering the samples according to morphology and composition data. This work constitutes a groundbreaking step towards uncovering this intricate writing tool

    Introdução: A ruptura uterina leva a consequências graves materno-fetais. A maioria dos casos ocorre em grávidas com cesarianas anteriores ou incisões uterinas prévias como miomectomia, raramente ocorrendo em úteros sem cicatrizes. Um dos principais factores correlacionado com o risco de ruptura é o tipo de incisão da histerotomia prévia: clássica (4-9%), em T (4-9%), vertical (1-7%); transversa (0,2-1,5%). Outros factores de risco são: ausência de parto vaginal anterior, indução do trabalho de parto, gravidez de termo, macrossomia fetal, multiparidade, sutura simples vs.dupla na histerorrafia prévia e intervalo curto entre gestações. 1-Caso clínico: Grávida, 28 anos, IO 2002 (cesariana em 2002 por apresentação pélvica; PTE em 2009), enviada ao nosso hospital para esclarecimento de anemia às 21 semanas. A gravidez decorreu normalmente; entrando espontaneamente em trabalho de parto em Agosto/2010. No período expulsivo a grávida referiu dor pélvica súbita com irradiação lombar. Teve um parto eutócico com distócia de ombros leve. Duas horas após, a puérpera apresentava-se inquieta, pálida e hipotensa comHb de 7,3g/dl. Decidiu-se laparotomia, constatando-se ruptura uterina no segmento inferior com prolongamento para a parede posterior, realizando-se histerorrafia.Pós-operatório sem intercorrências. 2-Caso clínico: Grávida, 41 anos, IO 0000, antecedentes pessoais de miomectomia por laparoscopia sem entrada na cavidade em 2008 e 2009, enviada ao nosso hospital para Consulta de DPN. Foi internada às 17+3 semanas para IMG por alteração do cariótipo fetal (Trissomia 21). Iniciou-se o protocolo para IMG aplicando-se unicamente 100 microg de misoprostol;24 horas após, a doente encontrava-se agitada e hipotensa, com episódio de lipotímia. Realizou-se laparotomia com visualização de ruptura uterina fúndica, corrigida com histerorrafia sem intercorrências Conclusão: Dada amorbi/mortalidade materno-fetal associada à ruptura uterina é fundamental reconhecer os factores de risco e os sintomas associados a esta, tal como o seu diagnóstico atempado e resolução imediata, minimizando os riscos materno-fetais

    Bat conservation and zoonotic disease risk: a research agenda to prevent misguided persecution in the aftermath of COVID-19

    Letter to the EditorCOVID-19 has spread around the globe, with massive impacts on global human health, national economies and conservation activities. In the timely editorial about conservation in the maelstrom of COVID-19, Evans et al. (2020) urged the conservation community to collaborate with other relevant sectors of society in the search for solutions to the challenges posed by the current pandemic, as well as future zoonotic outbreaks. Considering the association of COVID 19 with bats (Zhou et al., 2020), bat conservationists will undoubtedly be key actors in this dialogue, and thus an action plan on how best to adjust bat conservation to this new reality, alongside a transdisciplinary research agenda, are clear prioritiesinfo:eu-repo/semantics/publishedVersio

    Molecular evidence of Ebola Reston virus infection in Philippine bats

    Background: In 2008-09, evidence of Reston ebolavirus (RESTV) infection was found in domestic pigs and pig workers in the Philippines. With species of bats having been shown to be the cryptic reservoir of filoviruses elsewhere, the Philippine government, in conjunction with the Food and Agriculture Organization of the United Nations, assembled a multi-disciplinary and multi-institutional team to investigate Philippine bats as the possible reservoir of RESTV. Methods: The team undertook surveillance of bat populations at multiple locations during 2010 using both serology and molecular assays. Results: A total of 464 bats from 21 species were sampled. We found both molecular and serologic evidence of RESTV infection in multiple bat species. RNA was detected with quantitative PCR (qPCR) in oropharyngeal swabs taken from Miniopterus schreibersii, with three samples yielding a product on conventional hemi-nested PCR whose sequences differed from a Philippine pig isolate by a single nucleotide. Uncorroborated qPCR detections may indicate RESTV nucleic acid in several additional bat species (M. australis, C. brachyotis and Ch. plicata). We also detected anti-RESTV antibodies in three bats (Acerodon jubatus) using both Western blot and ELISA. Conclusions: The findings suggest that ebolavirus infection is taxonomically widespread in Philippine bats, but the evident low prevalence and low viral load warrants expanded surveillance to elaborate the findings, and more broadly, to determine the taxonomic and geographic occurrence of ebolaviruses in bats in the region. © 2015 Jayme et al

    The future of zoonotic risk prediction

    Get PDF
    In the light of the urgency raised by the COVID-19 pandemic, global investment in wildlife virology is likely to increase, and new surveillance programmes will identify hundreds of novel viruses that might someday pose a threat to humans. To support the extensive task of laboratory characterization, scientists may increasingly rely on data-driven rubrics or machine learning models that learn from known zoonoses to identify which animal pathogens could someday pose a threat to global health. We synthesize the findings of an interdisciplinary workshop on zoonotic risk technologies to answer the following questions. What are the prerequisites, in terms of open data, equity and interdisciplinary collaboration, to the development and application of those tools? What effect could the technology have on global health? Who would control that technology, who would have access to it and who would benefit from it? Would it improve pandemic prevention? Could it create new challenges? This article is part of the theme issue 'Infectious disease macroecology: parasite diversity and dynamics across the globe'.Peer reviewe

    Possibility for reverse zoonotic transmission of SARS-CoV-2 to free-ranging wildlife: a case study of bats

    Get PDF
    The COVID-19 pandemic highlights the substantial public health, economic, and societal consequences of virus spillover from a wildlife reservoir. Widespread human transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) also presents a new set of challenges when considering viral spillover from people to naïve wildlife and other animal populations. The establishment of new wildlife reservoirs for SARS-CoV-2 would further complicate public health control measures and could lead to wildlife health and conservation impacts. Given the likely bat origin of SARS-CoV-2 and related beta-coronaviruses (β-CoVs), free-ranging bats are a key group of concern for spillover from humans back to wildlife. Here, we review the diversity and natural host range of β-CoVs in bats and examine the risk of humans inadvertently infecting free-ranging bats with SARS-CoV-2. Our review of the global distribution and host range of β-CoV evolutionary lineages suggests that 40+ species of temperate-zone North American bats could be immunologically naïve and susceptible to infection by SARS-CoV-2. We highlight an urgent need to proactively connect the wellbeing of human and wildlife health during the current pandemic and to implement new tools to continue wildlife research while avoiding potentially severe health and conservation impacts of SARS-CoV-2 "spilling back" into free-ranging bat populations
