A systematic review with meta-analysis based on the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The search was carried out in the BDENF, SciELO, Cuiden, PsycINFOe, CINAHL, Embase, LILACS, and MEDLINE databases, as well as the AgeLine, Google Scholar and ScienceDirect academic search engines. The protocol was registered with PROSPERO (CRD42021292689). Random effects models were used for a meta-analysis of the prevalence obtained from individual studies. A total of 104 studies were included in the meta-analysis on antihypertensive treatment in the Brazilian population, totaling 38,299 patients. The most used instrument was the four-item Morisky-Green Test (49.5%). The adherence prevalence estimated by the meta-analysis was 44.4% (95%CI: 39.12%-49.94%, I2 = 91.17, p < 0.001), showing high heterogeneity. The adherence to antihypertensive treatment prevalence found in national studies was unsatisfactory, demonstrating that this problem continues to be a major challenge.

RESUMO

Background: Repurposed drugs for treatment of new onset disease may be an effective therapeutic shortcut. We aimed to evaluate the efficacy of repurposed antivirals compared to placebo in lowering SARS-CoV2 viral load of COVID-19 patients. Methods: REVOLUTIOn is a randomised, parallel, blinded, multistage, superiority and placebo controlled randomised trial conducted in 35 centres in Brazil. We include patients aged 18 years or older admitted to hospital with laboratory-confirmed SARS-CoV-2 infection, symptoms onset 9 days or less and SpO2 94% or lower at room air were eligible. All participants were randomly allocated to receive either atazanavir, daclatasvir or sofosbuvir/daclatasvir or placebo for 10 days. The primary outcome was the decay rate (slope) of the SARS-CoV-2 viral load logarithm assessed in the modified intention to-treat population. This trial was registered with ClinicalTrials.gov, number NCT04468087. Findings: Between February 09, 2021, and August 04, 2021, 255 participants were enrolled and randomly assigned to atazanavir (n = 64), daclatasvir (n = 66), sofosbuvir/daclatasvir (n = 67) or placebo (n = 58). Compared to placebo group, the change from baseline to day 10 in log viral load was not significantly different for any of the treatment groups (0.05 [95% CI, -0.03 to 0.12], -0.02 [95% CI, -0.09 to 0.06], and -0.03 [95% CI, -0.11 to 0.04] for atazanavir, daclatasvir and sofosbuvir/daclatasvir groups respectively). There was no significant difference in the occurrence of serious adverse events between treatment groups. Interpretation: No significant reduction in viral load was observed from the use of atazanavir, daclatasvir or sofosbuvir/daclatasvir compared to placebo in hospitalised COVID-19 patients who need oxygen support with symptoms onset 9 days or less.

RESUMO

BACKGROUND: Nonadherence to antihypertensive treatment is one of the main causes of the lack of blood pressure (BP) control. The coronavirus disease (COVID-19) pandemic imposes substantial social restriction impairing the medical care routine, which may influence adherence to the antihypertensive treatment. To assess the rate of nonadherence to antihypertensive drug treatment during the COVID-19 pandemic. METHODS: This is a cross-sectional study evaluating hypertensive adult patients from a tertiary outpatient clinic. From March to August 2020, patients were interviewed by telephone during the social distancing period of the COVID-19 pandemic. We evaluated biosocial data, habits, attitudes, and treatment adherence using the 4-item Morisky Green Levine Scale during the social distancing. Uncontrolled BP was defined by BP ≥ 140/90 mmHg. Clinical and prescription variables for drug treatment were obtained from the electronic medical record. We performed a multivariate analysis to determine the predictors of nonadherence to BP treatment. RESULTS: We studied 281 patients (age 66 ± 14 years, 60.5% white, 62.3% women, mean education of 9.0 ± 4 years of study). We found that 41.3% of the individuals reported poor adherence to antihypertensive drug treatment and 48.4% had uncontrolled BP. Subsample data identified that adherence was worse during the pandemic than in the previous period. The variables that were independently associated with the nonadherence during the pandemic period were black skin color (odds ratio [OR], 2.62; 95% confidence interval [CI], 1.46-4.68), and intermittent lack of access to antihypertensive medication during the pandemic (OR, 2.56; 95% CI, 1.11-5.89). CONCLUSIONS: Beyond traditional variables associated with poor adherence, the lack of availability of antihypertensive medications during the study underscore the potential role of pandemic on hypertension burden.

RESUMO

Growing concern about climate change has been driving the search for solutions to mitigate greenhouse gas emissions. In this context, carbon capture and utilization (CCU) technologies have been proposed and developed as a way of giving CO2 a sustainable and economically viable destination. An interesting approach is the conversion of CO2 into valuable chemicals, such as methanol (MeOH) and dimethyl ether (DME), by means of catalytic hydrogenation on Cu-, Zn-, and Al-based catalysts. In this work, three catalysts were tested for the synthesis of MeOH and DME from CO2 using a single fixed-bed reactor. The first one was a commercial CuO/γ-Al2O3; the second one was CuO-ZnO/γ-Al2O3, obtained via incipient wetness impregnation of the first catalyst with an aqueous solution of zinc acetate; and the third one was a CZA catalyst obtained by the coprecipitation method. The samples were characterized by XRD, XRF, and N2 adsorption isotherms. The hydrogenation of CO2 was performed at 25 bar, 230°C, with a H2:CO2 ratio of 3 and space velocity of 1,200 ml (g cat · h)-1 in order to assess the potential of these catalysts in the conversion of CO2 to methanol and dimethyl ether. The catalyst activity was correlated to the adsorption isotherms of each reactant. The main results show that the highest CO2 conversion and the best yield of methanol are obtained with the CZACP catalyst, very likely due to its higher adsorption capacity of H2. In addition, although the presence of zinc oxide reduces the textural properties of the porous catalyst, CZAWI showed higher CO2 conversion than commercial catalyst CuO/γ-Al2O3.

RESUMO

Teleconsultation can be classified as an advanced practice nursing that requires nurses' clinical reasoning based on a consistent theoretical framework to use in the nursing process. Our study conducted a theoretical-reflective analysis, based on Callista Roy's Adaptation Model of Nursing and Chick-Meleis' Transition Theory, about the contribution of teleconsultation as an advanced practice nursing in the care of older adults with chronic diseases during the COVID-19 pandemic. We reflect on this in two moments: "nursing theories and dealing with COVID-19" and "ways of adapting to new care models and advanced practice nursing," based on communication and information technologies. The worsening of the pandemic in Brazil changed life cycles, health/disease and organizational processes, demanding the development of an adaptive-transactional state by users and health care providers. Thus, information and communication technologies combined with advanced practice nursing can relieve social distancing and its repercussions on health care.

RESUMEN La teleconsulta es una herramienta de la enfermería de práctica avanzada que requiere un razonamiento clínico de los profesionales de enfermería basado en un marco teórico consistente para aplicarse en el proceso de enfermería. Este estudio realizó un análisis teórico-reflexivo, basado en el Modelo de Adaptación de Callista Roy y en la Teoría de las Transiciones de Chick-Meleis, sobre el aporte de la teleconsulta como herramienta de la enfermería de práctica avanzada a la atención de pacientes adultos mayores y de aquellos con enfermedades crónicas en el contexto de la pandemia del Covid-19. La reflexión se presenta en dos momentos: "teorías de enfermería y enfrentamiento al Covid-19" y "modos de adaptación a los nuevos modelos de asistencia y las prácticas avanzadas en enfermería", fundamentados en las tecnologías de la información y la comunicación. El avance de la pandemia en Brasil trajo cambios relacionados con los ciclos de vida, los procesos de salud/enfermedad y procesos organizacionales, que requirieron el desarrollo de un estado adaptativo-transaccional por parte de los usuarios y los profesionales de la salud. En este contexto, las tecnologías de la información y la comunicación, sumadas a la enfermería de práctica avanzada, jugaron un papel clave para mitigar el distanciamiento social y sus repercusiones en la asistencia sanitaria.

RESUMO A teleconsulta pode ser definida como uma prática avançada de enfermagem que requer do enfermeiro raciocínio clínico fundamentado em um arcabouço teórico consistente para aplicação no processo de enfermagem. No presente estudo, realizou-se uma análise teórico-reflexiva, fundamentada no Modelo de Adaptação de Callista Roy e na Teoria de Transição de Chick-Meleis, sobre a contribuição da teleconsulta como prática avançada de enfermagem no atendimento a pacientes idosos e com doenças crônicas no contexto da pandemia de covid-19. A reflexão é apresentada em dois momentos: "teorias de enfermagem e o enfrentamento da covid-19" e "formas de adaptação a novos modelos de assistência e as práticas avançadas em enfermagem", norteados pelas tecnologias de comunicação e informação. O agravamento da pandemia no Brasil trouxe mudanças relacionadas aos ciclos de vida, aos processos saúde/doença e organizacionais, demandando o desenvolvimento de um estado adaptativo-transacional por parte dos usuários e profissionais de saúde. Neste contexto, as tecnologias da informação e comunicação aliadas à prática avançada de enfermagem representam papel fundamental para atenuar o distanciamento social e suas repercussões na assistência à saúde.

RESUMO

Background: Congenital anomalies are structural, functional, or metabolic defects caused by a combination of environmental, genetic, or even iatrogenic factors. Genetic defects, which can be inherited, are more common in purebred dogs. Teratogenic factors such as radiation, toxins, chemical agents, infectious diseases, mechanical influences, drugs given to the mother, and nutrition can affect the litter during gestational development. The incomplete division of a fertilized egg results in monozygotic, conjoined or Siamese twins, which are animals with complete or incomplete duplications. This paper reports on an adult bitch with monocephalus dipygus dibrachius and the surgical procedures. Case: A 2-year-old female Shih Tzu weighing 5 kg was admitted to a veterinary clinic, presenting with swelling and myiasis near the anus and several development disorders, characterized by 2 pelvises, 2 anuses, 2 vulvas, 2 forelimbs and 6 hindlimbs. Her physiological parameters were otherwise normal. Only the dog's myiasis was treated at this time due to the owner's financial straits. After 5 months, the owner brought the bitch back to the veterinary clinic because the animal presented with fecaloma in 1 of the anuses. Radiography revealed numerous alterations: seven lumbar vertebrae with marked vertebral axis deviation, reduced disc space, as well as ankylosis and fused ventral spondylosis at L6 and L7. Two pelvises fused medially by the wings of the ileum, with slight deviation and thinning of pelvic bones. Four hip joints and medial joints with pelvic avulsion and bone remnants of the pelvic limbs. Acetabular tearing slightly flattened femoral head and thickened femoral neck. Caudal vertebrae and vertebral axis located in left pelvis. Left lateral patella inserted in the trochlear groove and lateral dislocation of right patella. Right patellofemoral joint with smooth surface, preserved intra-articular density and cranial displacement of the tibia relative to the femoral condyles (cranial cruciate ligament rupture). An ultrasound analysis revealed 2 bladders. Two months later surgery was performed due to recurrent complications. During laparotomy 2 uteruses, 2 bladders and bifurcation of the intestine were observed. Ovariosalpingohysterectomy was performed in both uterus and enterectomy of the problematic intestinal portion. After 2 days of the surgery, blood transfusion was performed. After 2 days of the transfusion, there was extravasation of yellow fluid from the surgical cut and abdominal palpation was indicative of bladder rupture, so the patient was sent to emergency surgery. Unilateral nephrectomy and ureterectomy, and ruptured bladder cystectomy were performed. The dog remained hospitalized for 24 days after surgery, before it was released. Discussion: The classification of conjoined twins is based on the location of the junction and the number of limbs. Monocephalus dipygus dibrachius was diagnosed based on the fact that the dog had 1 skull, 2 thoracic limbs and 4 pelvic limbs, as well as the corresponding genitourinary and gastrointestinal tract alterations. Imaging scans are extremely important for a proper diagnosis to ensure appropriate surgery planning. The bitch was the result of inbreeding between a male dog and its offspring, which probably contributed to this malformation. There are very few reports of surviving adult conjoined animals, and even fewer descriptions of successful surgical treatments. To the best of knowledge of the authors, there are no previous reports of a surviving adult dog suffering from this malformation.

RESUMO

The tick species and tick-borne pathogens present in a group of questing ticks collected from forest fragments in a rural area in the municipality of Divino, Minas Gerais state, Brazil were evaluated. The collected ticks were divided into two groups those collected from around the edges of the fragments and those collected from the interior of the forest. In all the fragments, the ticks were collected using a dragging and flagging technique and by harvesting them from white fabric gaiters. The larvae, nymphs, and adults were all morphologically identified using specific taxonomic keys. The larvae were identified to the genus level. DNA was extracted from the ticks and tested for the presence of Rickettsia spp., Borrelia spp., Ehrlichia spp., Anaplasma spp., Babesia spp., and Theileria spp. using a conventional polymerase chain reaction (PCR). In total, 1,122 questing ticks (750 larvae, 367 nymphs, and five adults) and 18 larval clusters were evaluated. The main species found in the collected tick population were Amblyomma sculptum, A. auricularium, A. aureolatum, and A. pseudoconcolor, along with the larvae of Amblyomma spp. and Dermacentor spp. None of the tick samples gave a positive result when tested by PCR for the presence of DNA from Rickettsia spp., Borrelia spp., Ehrlichia spp., Anaplasma spp., Babesia spp., or Theileria spp.(AU)

Neste estudo avaliou-se a presença de espécies de carrapatos e a detecção de agentes patogênicos a eles associados. Os carrapatos de vida livre foram coletados em fragmentos florestais da área rural do Município de Divino, Minas Gerais, Brasil. Os carrapatos coletados foram divididos em dois grupos, aqueles que foram coletados na área da margem do fragmento (Borda) e os coletados no interior da floresta (Mata). Em todos os fragmentos, os carrapatos foram coletados de acordo com a técnica de arraste aéreo ou no chão e com o uso de perneiras e de flanela. Tanto, as larvas, quanto as ninfas e os adultos foram morfologicamente identificados usando chaves taxonômicas específicas. No caso das larvas, estas foram identificadas até o nível de gênero. Foi realizada extração de DNA dos carrapatos e o DNA extraído foi testado para a presença de Rickettsia spp., Borrelia spp., Ehrlichia spp., Anaplasma spp., Babesia spp., e Theileria spp. por meio de uma estratégia de reação em cadeia da polimerase convencional. No total, 1.122 carrapatos em fase de vida livre (750 larvas, 367 ninfas e 5 adultos) e 18 clusters de larvas foram usados no estudo. As principais espécies identificadas na população de carrapatos coletada foram: Amblyomma sculptum, Amblyomma auricularium, Amblyomma aureolatum e Amblyomma pseudoconcolor e larvas de Amblyomma spp. e Dermacentor spp. Como resultado da detecção de patógenos não foi possível achar DNA de nenhum dos agentes analisados, assim todas as amostras de DNA dos carrapatos testados foram negativas tanto para Rickettsia spp. quanto para Borrelia spp., Ehrlichia spp., Anaplasma spp., Babesia spp. e Theileria spp.(AU)
