Resumen Antecedentes: El archipiélago cubano posee la mayor diversidad de cactus en el Caribe. Pese a que en los últimos años se han realizado numerosos estudios que facilitan la delimitación de sus especies, los inventarios existentes aún no han considerado toda la evidencia disponible. Preguntas: ¿Cuántos cactus nativos y naturalizados hay en Cuba? ¿Qué porcentaje de los cactus nativos son endémicos? Especies de estudio: Familia Cactaceae. Sitio y años de estudio: Cuba, 2013-2023. Métodos: Se revisó la información disponible sobre cactáceas cubanas donde se incluyeran listas o descripciones de especies, estudios taxonómicos, sistemáticos y filogenéticos. Además, se realizó un extenso trabajo de campo durante una década que abarcó toda la isla de Cuba. Se consideraron especies nativas las que están presentes en el archipiélago debido a causas naturales y que no llegaron debido a la intervención humana, mientras como especie naturalizada se consideraron las que fueron introducidas, intencional o no, por diferentes actividades humanas y que pueden reproducirse (sexual o asexual) de forma regular y mantener poblaciones por varias generaciones sin la intervención antrópica. Resultados: Registramos para Cuba 71 especies nativas o naturalizadas de 20 géneros de cactus, de estas, 49 especies son nativas (75.51 % endémicas) y 22 naturalizadas. Conclusiones: Cuba se ratifica como la isla con mayor diversidad de cactus en el Caribe.

Abstract Background: The Cuban archipelago has the greatest diversity of cactus in the Caribbean. Although in recent years there have been numerous studies that facilitate the delimitation of their species, existing inventories have not yet considered all available evidence. Questions: How many native and naturalized cacti are there in Cuba? What percentage of native cacti are endemic? Studied species: Cactaceae family. Study site and dates: Cuba, 2013-2023. Methods: The information available on Cuban cacti was reviewed that includes lists or descriptions of species, taxonomic, systematic and phylogenetic studies. In addition, an extensive field work was carried out for a decade that covered the entire island of Cuba. Native species were considered that are present in the archipelago due to natural causes and that did not arrive due to human intervention, while as a naturalized species, those that were introduced, intentional or not, by different human activities and that can be reproduced (sexual or asexual) regularly and maintain populations for several generations without anthropic intervention. Results: We recorded for Cuba 71 native or naturalized species of 20 genera of cacti, of these, 49 species are native (75.51 % endemic) and 22 naturalized. Conclusions: Cuba is ratified as the island with greater diversity of cactus in the Caribbean.

Abstract: En | Text: En | PDF: En

Objectives: To summarize evidence-based cognitive-behavioral therapy (CBT) treatment and propose clinical interventions for adult patients with obsessive-compulsive disorder (OCD). Methods: The literature on CBT interventions for adult OCD, including BT and exposure and response prevention, was systematically reviewed to develop updated clinical guidelines for clinicians, providing comprehensive details about the necessary procedures for the CBT protocol. We searched the literature from 2013-2020 in five databases (PubMed, Cochrane, Embase, PsycINFO, and Lilacs) regarding study design, primary outcome measures, publication type, and language. Selected articles were assessed for quality with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association. Results: We examined 44 new studies used to update the 2013 American Psychiatric Association guidelines. High-quality evidence supports CBT with exposure and response prevention techniques as a first-line treatment for OCD. Protocols for Internet-delivered CBT have also proven efficacious for adults with OCD. Conclusion: High-quality scientific evidence supports the use of CBT with exposure and response prevention to treat adults with OCD.

Abstract: En | Text: En | PDF: En

Objectives: To summarize evidence-based pharmacological treatments and provide guidance on clinical interventions for adult patients with obsessive-compulsive disorder (OCD). Methods: The American Psychiatric Association (APA) guidelines for the treatment of OCD (2013) were updated with a systematic review assessing the efficacy of pharmacological treatments for adult OCD, comprising monotherapy with selective serotonin reuptake inhibitors (SSRIs), clomipramine, serotonin and norepinephrine reuptake inhibitors (SNRIs), and augmentation strategies with clomipramine, antipsychotics, and glutamate-modulating agents. We searched for the literature published from 2013-2020 in five databases, considering the design of the study, primary outcome measures, types of publication, and language. Selected articles had their quality assessed with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association (ACC/AHA). Results: We examined 57 new studies to update the 2013 APA guidelines. High-quality evidence supports SSRIs for first-line pharmacological treatment of OCD. Moreover, augmentation of SSRIs with antipsychotics (risperidone, aripiprazole) is the most evidence-based pharmacological intervention for SSRI-resistant OCD. Conclusion: SSRIs, in the highest recommended or tolerable doses for 8-12 weeks, remain the first-line treatment for adult OCD. Optimal augmentation strategies for SSRI-resistant OCD include low doses of risperidone or aripiprazole. Pharmacological treatments considered ineffective or potentially harmful, such as monotherapy with antipsychotics or augmentation with ketamine, lamotrigine, or N-acetylcysteine, have also been detailed.

Abstract: Introduction: Distance learning emerged as an emergency tool used in Higher Education during the COVID-19 pandemic. These circumstances led to the increased use of Information and Communication Technologies (ICTs) for teaching and learning in Medicine courses. Objective: To conduct an integrative review to clarify the main positive and negative aspects found in the exercise of medical education in these atypical conditions. Method: Articles were searched on the following databases: Virtual Health Library (VHL), Embase, Education Resources Information Center (ERIC), Medline (via PubMed), Scopus and Web of Science Result: At the end of the screening and selection processes, 69 articles were included, from which information was extracted regarding the characteristics, positive and negative aspects of each remote medical teaching experience offered during the pandemic. Among the main positive aspects, we highlight the positive evaluation of the curricular component by the students, greater student autonomy, greater participation and communication among students and the absence of any learning deficit. The main negative points include the suspension of practical classes, complications arising from the use of technologies (connectivity, training and organization) and lack of social contact. Conclusion: It is observed that student autonomy and self-discipline is a crucial factor in taking full advantage of the distance learning approach, and perhaps the classic face-to-face student was not prepared for such a sudden change. Still, it is clear that, due to the urgency of implementing this new form of learning, distance learning has not had enough time to mature and be perfected to the point of being considered a medical education strategy applicable in the long term. Distance learning was crucial for the continued training of new doctors for an extended period of time. However, it needs to be reassessed and improved as a pedagogical strategy that uses ICTs for medical education.

Resumo: Introdução: O ensino remoto surgiu como ferramenta emergencial no processo de educação superior durante a pandemia da Covid-19. Nesse cenário, amplia-se a possibilidade de ensinar e aprender por meio das tecnologias da informação e comunicação (TIC) nos cursos de Medicina. Objetivo: Este estudo teve como objetivo realizar uma revisão integrativa que esclareça os principais aspectos positivos e negativos encontrados no exercício do ensino médico, nessas condições atípicas. Método: A busca dos artigos se deu nas seguintes bases: Biblioteca Virtual em Saúde (BVS), Embase, Education Resources Information Center (ERIC), Medline (via PubMed), Scopus e Web of Science. Resultado: Ao final dos processos de triagem e seleção, incluíram-se 69 artigos, dos quais foram extraídas informações quanto às características dos aspectos positivos e negativos de cada experiência de ensino remoto médico ofertado nesse período pandêmico. Entre os principais aspectos positivos, destacam-se a avaliação positiva do componente curricular pelos estudantes, a maior autonomia do aluno, a maior participação e comunicação entre os alunos, e a ausência de déficit de aprendizado. Entre os principais pontos negativos, observam-se a suspensão das aulas práticas, as complicações decorrentes do uso das tecnologias (conectividade, capacitação e organização) e a ausência de contato social. Conclusão: Observa-se que a autonomia e a autodisciplina discentes são fatores cruciais para o aproveitamento pleno de abordagem de aprendizagem remotamente, e talvez o aluno presencial clássico não estivesse preparado para tal mudança brusca. Ainda, percebe-se que, pela urgência de implantação dessa nova forma de aprendizagem, o ensino remoto não tenha tido tempo e maturidade o suficiente para que fosse aperfeiçoado ao ponto de ser considerado uma estratégia de educação médica aplicável em longo prazo. O ensino remoto foi crucial para que a formação de novos médicos não fosse descontinuada por um período de tempo tão extenso. Porém, o ensino remoto precisa ser reavaliado e aperfeiçoado como estratégia pedagógica que utiliza TIC para o ensino médico.

Abstract Background International publications have shown that the COVID-19 pandemic has negatively impacted the indicators of care for ST-segment elevation acute myocardial infarction (STEMI), with a potential increase in morbidity and mortality. Objectives To compare mortality, time from symptom onset to primary angioplasty (total delay [TD]), time from symptom onset to initial medical contact (patient delay [PD]), and time from initial medical contact to guidewire insertion in the hemodynamics laboratory (system delay [SD]) among patients admitted for STEMI at the Hemodynamics Service of Santa Casa de Passos, Minas Gerais, Brazil before and after the declaration of the COVID-19 pandemic by the World Health Organization, assessing the impact of the COVID-19 pandemic on STEMI care indicators. Methods This is a before-and-after study involving patients hospitalized with STEMI undergoing primary angioplasty. Data were collected retrospectively through medical record review. Clinical and demographic profiles and outcomes between the pre-pandemic and pandemic groups were compared using the chi-square test for categorical variables or Student's t-test for continuous variables. A significance level of p < 0.05 was adopted. Results There were no differences in TD (pre-pandemic: 300 min [± 159 min], 95% CI 277.1 to 322.6; pandemic: 300 min [± 148 min], 95% CI 274.3 to 326.6, p = 0.97). However, there was an increase in SD (pre-pandemic: 145 min [± 97 min], 95% CI 122.7 to 167.9; pandemic: 178 min [± 96 min], 95% CI 157.4 to 197.9, p = 0.037). There was no increase in PD (pre-pandemic: 145 min ± 133 min; pandemic: 130 min ± 117 min, p = 0.44), and no differences in mortality were observed (pre-pandemic: 9.7%; pandemic: 12%, p = 0.49). Conclusion The COVID-19 pandemic increased SD in the management of STEMI in the region of Passos, Minas Gerais. There were no differences in PD, TD, and in-hospital mortality.

Abstract: Introduction: Invasive procedures like the placement of catheters, probes, tubes, and electrodes in critically ill patients can cause immediate life-threatening complications. This review will approach the complications caused by central catheter and endotracheal tube. Therefore, recognizing the different anatomical markers that serve as guidance to assure the proper placement of these medical devices using different imaging modalities, favors the early detection of potential complications. Material and methods: A detailed review of the literature about the subject was carried out, and representative cases from the imaging department of Hospital Angeles Lomas, were analyzed to describe the anatomical markers used to evaluate the correct location of medical devices such as central catheter and endotracheal tube placed in critically ill patients. The appearance and complications of misplaced devices were also recorded. Results: We describe the anatomical markers that are useful to prove the adequate placement of different medical devices, as well as the most common complications and radiological appearances of misplaced devices. Conclusions: It is essential that radiologists and other physicians become familiar with the different imaging modalities used to evaluate the placement of medical devices, as well as being aware of the anatomical markers and the radiological appearance of properly positioned or misplaced devices and possible complications of their misplacement.

Resumen: Introducción: El empleo de dispositivos invasivos (catéteres, sondas, tubos, electrodos, etc.) en pacientes en estado crítico puede ocasionar complicaciones inmediatas que ponen en riesgo la vida; en esta revisión se abordarán las complicaciones asociadas a la colocación de tubo endotraqueal y catéter central, por lo que conocer los marcadores anatómicos que establezcan una guía para reconocer la adecuada colocación de estos dispositivos médicos mediante las diferentes modalidades de imagen favorece la detección temprana de las posibles complicaciones. Material y métodos: Se realizó una revisión bibliográfica detallada del tema, también se obtuvieron y analizaron imágenes representativas procedentes del Departamento de Imagenología del Hospital Angeles Lomas para describir los marcadores anatómicos utilizados con el fin de evaluar la localización del tubo endotraqueal y el catéter central colocados en pacientes críticos, y en el caso de los dispositivos mal localizados y las complicaciones generadas por los mismos. Resultados: Se logró establecer los diferentes marcadores anatómicos que indican una adecuada colocación de los distintos dispositivos. Conclusiones: Es esencial que el personal médico se familiarice con los estudios de imagen que se emplean para el monitoreo de los procedimientos, así como los marcadores anatómicos y la apariencia radiológica normal del adecuado posicionamiento de los dispositivos.

RESUMO Objetivo: Avaliar a frequência dos sintomas oftalmológicos, neurológicos e sistêmicos mais comuns em pacientes sintomáticos atendidos no serviço de triagem de COVID-19 do Hospital das Clínicas da UFPE. Métodos: Cento e quatro pacientes com suspeita clínica de infecção por Sars-Cov-2 foram submetidos a avaliação médica e aplicação de questionário sobre a sintomatologia oftalmológica, neurológica e sistêmica. Todos os participantes do estudo tiveram exame de RT-PCR para COVID-19 solicitado. Resultados: A média de idade foi de 38,8 anos, com 44,23% entre 31 e 40 anos. Mulheres corresponderam a 68,27% dos atendimentos e homens a 31,73%. Os sintomas mais frequentes nos pacientes com RT-PCR positivo foram: tosse (69,23%), febre (42,3%), mialgia (38,46%), hiposmia (38,46%), e ageusia (30,77%). Neste grupo, os sintomas oftalmológicos estiveram presentes em 34,61%, sendo: ardor (19,23%), dor ocular (11,54%), sensação de corpo estranho (7,7%), hiperemia (7,7%) e lacrimejamento (3,84%) os mais encontrados. Conclusões: O quadro clínico sistêmico foi característico de infecção respiratória alta, porém os achados neurológicos de hiposmia e anosmia mostraram-se importantes marcadores para a suspeição dos casos de infecção por COVID-19. Os sintomas oftalmológicos dos pacientes com COVID-19 foram semelhantes aos presentes em outros quadros virais, podendo preceder o quadro sistêmico. Houve uma alta taxa de automedicação para os sintomas gerais quando comparado ao quadro oftalmológico.

ABSTRACT Purpose: This study evaluated the frequency of the most common ophthalmological, neurological, and systemic findings in symptomatic patients seen at a COVID-19 screening service at Hospital das Clínicas - Universidade Federal de Pernambuco. Methods: A total of 104 patients under clinical suspicion of SARS-CoV-2 infection underwent medical evaluation through an ophthalmological and systemic symptoms survey. All participants selected for the study underwent COVID-19 RT-PCR testing. Results: The mean age was 38.8 years, with 44.23% between 31 and 40 years old, 68.27% female, and 31.73% male. The most common symptoms in patients with a positive RT-PCR test were cough (69.23%), fever (42.3%), hyposmia (38.46%), myalgia (38.46%), and ageusia (30.77%). In the positive group, 34.61% presented with ophthalmological symptoms: burning (19.23%), eye pain (11.54%), foreign body sensation (7.7%), hyperemia (7.7%), and tearing (3.84%). Conclusions: Systemic clinical features were characteristic of upper respiratory infection, but neurological findings of hyposmia and anosmia proved to be important markers for suspicion of SARS-CoV-2 infection. Ophthalmic symptoms in patients with COVID-19 were similar to those observed in other viral conditions and may precede systemic conditions. A high rate of self-medication was observed for general symptoms compared with ophthalmological conditions.

ABSTRACT Coronary artery fistula draining into the coronary sinus is a rare vascular malformation, and its diagnosis and clinical manifestations usually occur late. We describe the case of a 72-year-old female patient with dyspnea on exertion (New York Heart Association Class III) associated with palpitations. The transthoracic echocardiogram showed significant tricuspid insufficiency. Cardiac catheterization showed aneurysm of the circumflex coronary artery and fistula of this artery draining into the coronary sinus. The patient underwent fistula ligation and tricuspid valve repair, with excellent surgical results.

RESUMO O entendimento da suscetibilidade de solos à erosão é crucial para o planejamento de uso da terra visando uma agricultura sustentável. O estudo teve como objetivo determinar a variabilidade espacial do potencial natural de erosão para o Estado de Mato Grosso, um importante centro agrícola do Brasil. O potencial natural de erosão foi calculado usando a Equação Universal de Perda de Solo, que considera a erosividade, erodibilidade e o fator topográfico. Para cada um desses três fatores foi criado um mapa em formato raster, que foi combinado em um Sistema de Informação Geográfica e usado para criar o mapa de potencial natural de erosão. O mapa foi, então, utilizado para separar classes do potencial natural de erosão para o Estado de Mato Grosso. O Estado predominantemente apresentou níveis médios de potencial natural de erosão (58,38% da área), seguido por altos (21,67%) e baixos (19,57%) níveis. As áreas de baixo potencial natural de erosão estão predominantemente localizadas nas partes mais planas do Estado. O fator topográfico apresentou forte correlação com o potencial natural de erosão, sendo um importante componente para auxiliar o planejamento do uso da terra e práticas de conservação do solo. Regiões consideradas com maiores potenciais naturais de erosão são mais comuns nas macrorregiões noroeste (46,69% da área), norte (32,7%) e oeste (30,05%).

ABSTRACT Understanding the susceptibility of soils to erosion is crucial for planning land use towards sustainable agriculture. This study aimed to determine the spatial variability of natural erosion potential for the state of Mato Grosso, an important agricultural center of Brazil. Natural erosion potential was calculated using the Universal Soil Loss Equation, which accounts for erosivity, erodibility, and the topographic factor. For each of these three factors, a map was generated in raster format that was combined into a Geographic Information System and used to create a map of natural erosion potential. This map was then used to separate classes of natural erosion potential for the state of Mato Grosso. The state predominantly has medium levels of natural erosion potential (58.38% in area), followed by high (21.67%) and low (19.57%) levels. Areas of low natural erosion potential are predominantly located in the flatter sections of the state. The topographic factor was strongly correlated with natural erosion potential. It is an important component to support land use planning and soil conservation practices. Regions considered to have high natural erosion potential are most commonly in the northwest (46.69% in area), north (32.7%), and west (30.05%) macro-regions.

Resumo Objetivou-se estimar a prevalência do acidente vascular cerebral (AVC) em brasileiros mais velhos, bem como identificar fatores sociodemográficos, de saúde, de serviços de saúde e ambientais associados à independência em atividades de vida diária. Trata-se de um estudo transversal de base populacional (Estudo Longitudinal da Saúde de Idosos Brasileiros 2015-2016). Dos 9.412 participantes, 536 indivíduos (≥ 50 anos) tiveram AVC e foram incluídos. A prevalência do AVC foi de 5,3% em indivíduos com 50 anos e mais, aumentando para 8% entre indivíduos com 75 anos e mais, com padrão dissimilar entre sexo. A independência foi associada à velocidade da marcha (razão de prevalência [RP] 2,72, IC95%: 1,96-3,77), atividade física (PR 1,24; IC95%: 1,04-1,47) e uso de dispositivos auxiliares de marcha (RP 0,63; IC95%: 0,41-0,96). Encontrou-se interação significativa para velocidade da marcha, adaptações no domicílio e a independência (RP 3,42; IC95%: 1.04-11.29). A probabilidade de independência foi de 40% nas velocidades mais baixas (< 0,4 m/s), e nas velocidades mais elevadas (> 0,8 m/s) foi de 70%, aumentando para 90% quando há adaptações no domicílio. A velocidade rápida da marcha e a adaptação no domicílio foram os principais fatores associados à independência a longo prazo após o AVC.

Abstract This study aimed at estimating the prevalence of stroke in older adults in Brazil, and at identifying the sociodemographic, health-related, health service-related, and environmental factors associated with independence in daily activities. Across-sectional, population-based study (Brazilian Longitudinal Study of Aging 2015-2016) was conducted. 536 individuals (≥ 50 years), from 9,412 participants, have had stroke and were included. Prevalence of stroke was 5.3% among individuals aged 50 years and over, increasing up to 8.0% among individuals aged 75 years and over, showing a dissimilar pattern between sex. Independence was associated with walking speed (Prevalence Ratio (PR) 2.72, 95%CI: 1.96 to 3.77), physical activity (PR 1.24; 95%CI: 1.04 to 1.47) and use of walking devices (PR 0.63; 95%CI: 0.41 to 0.96). A significant interaction was found between walking speed plus home adaptations and performance of daily living activities (PR 3.42; 95%CI: 1.04 to 11.29). The probability of independence was 40% among slow walkers (< 0.4 m/s), increasing up to 70% among fast walkers (> 0.8 m/s), and to 90% among those who also have home adaptations. Faster walking speed combined with home adaptations was the main factor associated with long-term independence after stroke.

RESUMO Os medicamentos reaproveitados são importantes em contextos de recursos limitados porque as intervenções estão mais rapidamente disponíveis, já foram testadas com segurança em outras populações e são, em geral, mais baratas. Os medicamentos reaproveitados são uma solução eficaz, especialmente para doenças emergentes, como a COVID-19. O estudo REVOLUTIOn visa avaliar três medicamentos antivirais reaproveitados: atazanavir, daclatasvir e sofosbuvir, já utilizados em pacientes infectados pelo HIV ou pelo vírus da hepatite C, em um estudo randomizado, controlado por placebo, adaptativo, multibraço e em múltiplos estágios. Os medicamentos serão testados simultaneamente em um ensaio de Fase II para primeiro identificar se algum deles, isoladamente ou em combinação, reduz a carga viral. Se reduzirem, será iniciado um estudo de Fase III para investigar se tais medicamentos são capazes de aumentar o número de dias sem suporte respiratório. Os participantes devem ser adultos hospitalizados com idade ≥ 18 anos com início dos sintomas ≤ 9 dias e saturação de oxigênio ≤ 94% em ar ambiente ou necessidade de oxigênio suplementar para manter saturação de oxigênio > 94%. O tamanho total esperado da amostra varia entre 252 e 1.005 participantes, dependendo do número de estágios que serão concluídos no estudo. Assim, o protocolo é aqui descrito em detalhes, juntamente do plano de análise estatística. Em conclusão, o estudo REVOLUTIOn foi concebido para fornecer evidências se o atazanavir, o daclatasvir ou o sofosbuvir reduzem a carga viral de SARS-CoV-2 em pacientes com COVID-19 e aumentam o número de dias em que os pacientes ficam sem suporte respiratório. Neste artigo de protocolo, descrevem-se a fundamentação, o desenho e a situação do ensaio. Identificador do ClinicalTrials.gov:NCT04468087

ABSTRACT Repurposed drugs are important in resource-limited settings because the interventions are more rapidly available, have already been tested safely in other populations and are inexpensive. Repurposed drugs are an effective solution, especially for emerging diseases such as COVID-19. The REVOLUTIOn trial has the objective of evaluating three repurposed antiviral drugs, atazanavir, daclatasvir and sofosbuvir, already used for HIV- and hepatitis C virus-infected patients in a randomized, placebo-controlled, adaptive, multiarm, multistage study. The drugs will be tested simultaneously in a Phase II trial to first identify whether any of these drugs alone or in combination reduce the viral load. If they do, a Phase III trial will be initiated to investigate if these medications are capable of increasing the number of days free respiratory support. Participants must be hospitalized adults aged ≥ 18 years with initiation of symptoms ≤ 9 days and SpO2 ≤ 94% in room air or a need for supplemental oxygen to maintain an SpO2 > 94%. The expected total sample size ranges from 252 to 1,005 participants, depending on the number of stages that will be completed in the study. Hence, the protocol is described here in detail together with the statistical analysis plan. In conclusion, the REVOLUTIOn trial is designed to provide evidence on whether atazanavir, daclatasvir or sofosbuvir decrease the SARS-CoV-2 load in patients with COVID-19 and increase the number of days patients are free of respiratory support. In this protocol paper, we describe the rationale, design, and status of the trial. ClinicalTrials.gov identifier:NCT04468087

Abstract Acrocarpus fraxinifolius stands out due to its uses in the timber industry and rapid growth. However, information is scarce regarding its fertilization. We aim to understand how soil preparation and phosphorus doses affect A. fraxinifolius initial development. The experimental design used was a randomized block design in a 2 x 5 factorial scheme, consisting of two types of soil tillage (minimum and conventional) and five doses of phosphorus (P) (0, 50, 100, 150, and 200 g of simple superphosphate) with four replications, and plots formed by two plants. The measurement occurs at 30 and 210 days after planting, assessing the height and diameter at the stem height. Initially, the minimum tillage provided had a higher average height and diameter. However, conventional tillage, acidity correction, and fertilization with 108 g of simple superphosphate per plant resulted in Acrocarpus fraxinifolius plants with better growth at 210 days after planting.
