RESUMEN

BACKGROUND: Previous trials have demonstrated the effects of fluvoxamine alone and inhaled budesonide alone for prevention of disease progression among outpatients with COVID-19. OBJECTIVE: To determine whether the combination of fluvoxamine and inhaled budesonide would increase treatment effects in a highly vaccinated population. DESIGN: Randomized, placebo-controlled, adaptive platform trial. (ClinicalTrials.gov: NCT04727424). SETTING: 12 clinical sites in Brazil. PARTICIPANTS: Symptomatic adults with confirmed SARS-CoV-2 infection and a known risk factor for progression to severe disease. INTERVENTION: Patients were randomly assigned to either fluvoxamine (100 mg twice daily for 10 days) plus inhaled budesonide (800 mcg twice daily for 10 days) or matching placebos. MEASUREMENTS: The primary outcome was a composite of emergency setting retention for COVID-19 for more than 6 hours, hospitalization, and/or suspected complications due to clinical progression of COVID-19 within 28 days of randomization. Secondary outcomes included health care attendance (defined as hospitalization for any cause or emergency department visit lasting >6 hours), time to hospitalization, mortality, patient-reported outcomes, and adverse drug reactions. RESULTS: Randomization occurred from 15 January to 6 July 2022. A total of 738 participants were allocated to oral fluvoxamine plus inhaled budesonide, and 738 received placebo. The proportion of patients observed in an emergency setting for COVID-19 for more than 6 hours or hospitalized due to COVID-19 was lower in the treatment group than the placebo group (1.8% [95% credible interval {CrI}, 1.1% to 3.0%] vs. 3.7% [95% CrI, 2.5% to 5.3%]; relative risk, 0.50 [95% CrI, 0.25 to 0.92]), with a probability of superiority of 98.7%. No relative effects were found between groups for any of the secondary outcomes. More adverse events occurred in the intervention group than the placebo group, but no important differences between the groups were detected. LIMITATION: Low event rate overall, consistent with contemporary trials in vaccinated populations. CONCLUSION: Treatment with oral fluvoxamine plus inhaled budesonide among high-risk outpatients with early COVID-19 reduced the incidence of severe disease requiring advanced care.

RESUMEN

Non-alcoholic fatty liver disease (NAFLD) is a metabolic disorder caused by excess consumption of hypercaloric foods. Guavira (Campomanesia sp.) pulp has broad technological applicability, yet the peel and seeds are considered industrial residue. The objective of this unprecedented study was to evaluate the effects of the flour from guavira's industrial residue (GF) consumption in rats fed with hypercaloric diet (HD). During 65 days, 50 rats were separated into a control group: 1%, 2%, 4% and 8% HD with GF complementation in the diet. The GF chemical composition, phenolic compounds, antioxidant capacity, serum biochemical parameters (glucose, cholesterol, HDL, non-HDL, triglycerides, AST, ALT, and oral glucose tolerance test), fat liver content, and hepatic histomorphology had been characterized. GF is mainly composed of fibres, with phenolic content of 7,391.09 mg AGE/100 g GF and relevant antioxidant capacity (IC50 2.22 and ORAC 155.68 µmol/TE g-1 ). Serum biochemical analysis did not differ statistically (except ALT reduction, p < .05). Fat liver content was smaller on HD2%GF (p < .0001). The control group and 1% GF showed greater diffuse microvesicular steatosis compared to the other groups when using hepatic morphological analysis (p < .05). GF consumption attenuated NAFLD caused by a hypercaloric diet, and this effect may be related to the fibre content and bioactive compounds in GF.

RESUMEN

Patients older than 75 years old with multiple myeloma (MM) have shorter survival and are usually treated differently from what features in clinical trials. In this study, the authors characterized the Portuguese population of MM patients above 75 years old, treated between 2009 and 2016. We compared the outcomes obtained with bortezomib-based protocols (BBP), thalidomide-based protocols (TBP), and chemotherapy (CT) using univariate and multivariate controlling for age, performance status, International Staging System score, renal impairment, and number of comorbidities. We retrieved data from 386 patients, treated in 12 hospitals. Three hundred thirty-one cases were analyzed: 119 patients treated with BBP, 65 with TBP, 147 with CT. Median age was 79 years; CT-treated patients were older, had a worse performance status, and have more comorbidities. The median follow-up was 25 months. The 2-year OS was 58% and the median OS was 29.5 months. Patients treated with BBP had more frequently very good partial response (VGPR) or better response, and the subgroup of more fit patients had a significantly longer progression-free survival (PFS) and OS. The most frequently grade 3-4 toxicities were hematologic, infectious, and neurologic and were significantly lower in TBP and CT groups vs BBP. The most common second line was CT, followed by lenalidomide. Patients treated with lenalidomide had a higher probability of VGPR or better and a superior 1-year PFS. Despite the limitations of a retrospective study, our cohort represents the reality of older patients with MM in a western country. The hazard of death or progression was higher for old, fit patients treated, in first line, with CT and with TBP compared with that of BBP.

RESUMEN

Congenital erythrocytosis (CE), or congenital polycythemia, represents a rare and heterogeneous clinical entity. It is caused by deregulated red blood cell production where erythrocyte overproduction results in elevated hemoglobin and hematocrit levels. Primary congenital familial erythrocytosis is associated with low erythropoietin (Epo) levels and results from mutations in the Epo receptor gene (EPOR). Secondary CE arises from conditions causing tissue hypoxia and results in increased Epo production. These include hemoglobin variants with increased affinity for oxygen (HBB, HBA mutations), decreased production of 2,3-bisphosphoglycerate due to BPGM mutations, or mutations in the genes involved in the hypoxia sensing pathway (VHL, EPAS1, and EGLN1). Depending on the affected gene, CE can be inherited either in an autosomal dominant or recessive mode, with sporadic cases arising de novo. Despite recent important discoveries in the molecular pathogenesis of CE, the molecular causes remain to be identified in about 70% of the patients. With the objective of collecting all the published and unpublished cases of CE the COST action MPN&MPNr-Euronet developed a comprehensive Internet-based database focusing on the registration of clinical history, hematological, biochemical, and molecular data (http://www.erythrocytosis.org/). In addition, unreported mutations are also curated in the corresponding Leiden Open Variation Database.

RESUMEN

INTRODUCTION: Congenital erythrocytosis can be classified as primary, when the defect is intrinsic to the RBC progenitors and independent of the serum erythropoietin (Epo) concentration, or secondary, when the erythrocytosis is the result of an upregulation of Epo production. Primary erythrocytosis is associated with mutations in the EPOR gene, secondary CE can de due to mutations that stabilize the hemoglobin in the oxygenated form or to mutations in the genes that control the transcriptional activation of the EPO gene - VHL, EGLN1, EPAS1. Chuvash polycythemia, caused by mutations in VHL gene, shares features of both primary and secondary erythrocytosis, with increased Epo production but also hypersensitivity of progenitors to Epo. MATERIAL AND METHODS: With the main objective of describing the etiology and molecular basis of CE, we have studied 70 consecutive unrelated patients presenting with idiopathic erythrocytosis from our hematology clinic or referred from other centers. According to a study algorithm, we have sequenced all the genes described as associated with CE. RESULTS AND DISCUSSION: Erythrocytosis molecular etiology was identify in 25 (36%) of the 70 subjects. High-affinity Hb variants were the most common cause, present in 20% of the cases. New mutations were identified in the JAK2, EPOR, VHL, and EGLN1 genes. CONCLUSIONS: High-affinity hemoglobin variants are a very rare cause of secondary CE, but it seems likely that their incidence may be underestimated. Our experience shows that in erythrocytosis with a dominant inheritance and normal or inappropriate high Epo levels, the HBB and HBA genes should be the first to be studied. In spite of the seven genes known to be involved in CE, the majority of the cases have unknown etiology.

RESUMEN

Mangabeira (Hancornia speciosa) is a Brazilian tree and a socioeconomic key due to the commercialization of its food products and tree parts to treat health conditions empirically. This review gathers the main chemical, and microbiological characteristics of the mangabeira tree parts (leaves, fruits, tree bark, latex, and seeds), emphasizing its applicability in food science and focusing on its bioapplicability in health conditions. Leaves, fruits, and tree bark can be used to develop functional foods, and phytochemical products; the tree latex have great potential in the bioengineering material field; and the seeds in sustainable energy production. Leaves and fruits were the main samples bioapplied in health conditions in vitro (oxidative stress and chemopreventive effect) and in vivo (gastrointestinal and cardiovascular health, anti-inflammatory, and antidiabetic effect), whereas tree bark and latex also exhibited health effects and seeds showed low cytotoxicity. All parts of the mangabeira tree can be explored by extractivist families and industries from a sustainable point of view.

RESUMEN

Normal cell counterparts of solid and myeloid tumors accumulate mutations years before disease onset; whether this occurs in B lymphocytes before lymphoma remains uncertain. We sequenced multiple stages of the B lineage in elderly individuals and patients with lymphoplasmacytic lymphoma, a singular disease for studying lymphomagenesis because of the high prevalence of mutated MYD88. We observed similar accumulation of random mutations in B lineages from both cohorts and unexpectedly found MYD88L265P in normal precursor and mature B lymphocytes from patients with lymphoma. We uncovered genetic and transcriptional pathways driving malignant transformation and leveraged these to model lymphoplasmacytic lymphoma in mice, based on mutated MYD88 in B cell precursors and BCL2 overexpression. Thus, MYD88L265P is a preneoplastic event, which challenges the current understanding of lymphomagenesis and may have implications for early detection of B cell lymphomas.

RESUMEN

PURPOSE: Early intervention in smoldering multiple myeloma (SMM) requires optimal risk stratification to avoid under- and overtreatment. We hypothesized that replacing bone marrow (BM) plasma cells (PC) for circulating tumor cells (CTC), and adding immune biomarkers in peripheral blood (PB) for the identification of patients at risk of progression due to lost immune surveillance, could improve the International Myeloma Working Group 20/2/20 model. EXPERIMENTAL DESIGN: We report the outcomes of 150 patients with SMM enrolled in the iMMunocell study, in which serial assessment of tumor and immune cells in PB was performed every 6 months for a period of 3 years since enrollment. RESULTS: Patients with >0.015% versus ≤0.015% CTCs at baseline had a median time-to-progression of 17 months versus not reached (HR, 4.9; P < 0.001). Presence of >20% BM PCs had no prognostic value in a multivariate analysis that included serum free light-chain ratio >20, >2 g/dL M-protein, and >0.015% CTCs. The 20/2/20 and 20/2/0.015 models yielded similar risk stratification (C-index of 0.76 and 0.78). The combination of the 20/2/0.015 model with an immune risk score based on the percentages of SLAN+ and SLAN- nonclassical monocytes, CD69+HLADR+ cytotoxic NK cells, and CD4+CXCR3+ stem central memory T cells, allowed patient' stratification into low, intermediate-low, intermediate-high, and high-risk disease with 0%, 20%, 39%, and 73% rates of progression at 2 years. CONCLUSIONS: This study showed that CTCs outperform BM PCs for assessing tumor burden. Additional analysis in larger series are needed to define a consensus cutoff of CTCs for minimally invasive stratification of SMM.

RESUMEN

BACKGROUND: Recent evidence indicates a potential therapeutic role of fluvoxamine for COVID-19. In the TOGETHER trial for acutely symptomatic patients with COVID-19, we aimed to assess the efficacy of fluvoxamine versus placebo in preventing hospitalisation defined as either retention in a COVID-19 emergency setting or transfer to a tertiary hospital due to COVID-19. METHODS: This placebo-controlled, randomised, adaptive platform trial done among high-risk symptomatic Brazilian adults confirmed positive for SARS-CoV-2 included eligible patients from 11 clinical sites in Brazil with a known risk factor for progression to severe disease. Patients were randomly assigned (1:1) to either fluvoxamine (100 mg twice daily for 10 days) or placebo (or other treatment groups not reported here). The trial team, site staff, and patients were masked to treatment allocation. Our primary outcome was a composite endpoint of hospitalisation defined as either retention in a COVID-19 emergency setting or transfer to tertiary hospital due to COVID-19 up to 28 days post-random assignment on the basis of intention to treat. Modified intention to treat explored patients receiving at least 24 h of treatment before a primary outcome event and per-protocol analysis explored patients with a high level adherence (>80%). We used a Bayesian analytic framework to establish the effects along with probability of success of intervention compared with placebo. The trial is registered at ClinicalTrials.gov (NCT04727424) and is ongoing. FINDINGS: The study team screened 9803 potential participants for this trial. The trial was initiated on June 2, 2020, with the current protocol reporting randomisation to fluvoxamine from Jan 20 to Aug 5, 2021, when the trial arms were stopped for superiority. 741 patients were allocated to fluvoxamine and 756 to placebo. The average age of participants was 50 years (range 18-102 years); 58% were female. The proportion of patients observed in a COVID-19 emergency setting for more than 6 h or transferred to a teritary hospital due to COVID-19 was lower for the fluvoxamine group compared with placebo (79 [11%] of 741 vs 119 [16%] of 756); relative risk [RR] 0·68; 95% Bayesian credible interval [95% BCI]: 0·52-0·88), with a probability of superiority of 99·8% surpassing the prespecified superiority threshold of 97·6% (risk difference 5·0%). Of the composite primary outcome events, 87% were hospitalisations. Findings for the primary outcome were similar for the modified intention-to-treat analysis (RR 0·69, 95% BCI 0·53-0·90) and larger in the per-protocol analysis (RR 0·34, 95% BCI, 0·21-0·54). There were 17 deaths in the fluvoxamine group and 25 deaths in the placebo group in the primary intention-to-treat analysis (odds ratio [OR] 0·68, 95% CI: 0·36-1·27). There was one death in the fluvoxamine group and 12 in the placebo group for the per-protocol population (OR 0·09; 95% CI 0·01-0·47). We found no significant differences in number of treatment emergent adverse events among patients in the fluvoxamine and placebo groups. INTERPRETATION: Treatment with fluvoxamine (100 mg twice daily for 10 days) among high-risk outpatients with early diagnosed COVID-19 reduced the need for hospitalisation defined as retention in a COVID-19 emergency setting or transfer to a tertiary hospital.

RESUMEN

We performed a systematic review to identify and summarize the effects of distinctive aerobic exercise (AE) protocols on chronic allergic lung inflammation reported in asthma animal models. We identified 255 preclinical studies of asthma and AE protocols by comprehensive searches in PubMed, ScienceDirect and LILACS for peer-reviewed journals, using the search components "exercise," "lung inflammation," and "asthma," without restrictions on publication date. Twenty-two studies were selected that met all eligibility criteria. Most studies used an ovalbumin experimental model and performed experiments with BALB/c mice. Most studies performed treadmill AE, using protocols of 30 to 60 minutes, 3 to 5 times/week, for 4 to 8 weeks. The results showed that the effects of AE on lungs were protocol dependent, but generaly, there was a decrease in inflammatory cell influx and Th2 cytokines, as well as an increase in anti-inflammatory defenses. However, the immunoregulation of globulins and nitric oxide levels in asthma seemed to be associated with the onset of AE. The results suggest that AE plays an important immunoregulatory role in animal models of asthma, with effects mainly mediated by increased anti-inflammatory defenses and reduced Th2 response. In parallel, prophylactic and therapeutic AE also played important roles in decreasing bronchial responsiveness and attenuating lung remodeling in animal models of asthma, secondary outcomes in this systematic review. The review protocol was published for free access in October 2017 on the Systematic Review Facility (SyRF) platform (http://syrf.org.uk/protocols/).

RESUMEN

The acute improvement of performance after photobiomodulation therapy (PBMT) has been reported in different types of exercise. However, the effect on high-intensity and intermittent exercises that are relevant for team sports is unknown. Thus, we evaluated the effect of prior acute application of PBMT on high-intensity and intermittent exercise performance, muscle oxygenation, and physiological/perceptual indicators in amateur female futsal players. Thirteen players (24.1 ± 3.7 years) performed a testing battery (countermovement jump (CMJ), Illinois agility and YoYo intermittent recovery test level 1 (YYIR1)) preceded by 15 min of PBMT (1 min 30 s each muscular point; five muscular points in each lower limbs) or 15 min of placebo (SHAM), in a counterbalanced randomized cross-over design (one-week in-between PBMT/SHAM). All test performance did not differ (p > 0.05) between PBMT and SHAM, as well as blood lactate, rating of perceived exertion, heart rate, and muscle oxygenation (via near infrared spectroscopy) responses. The acute application of PBMT prior to a physical testing battery does not influence high-intensity and intermittent exercises performance, neither physiological nor perceptual responses in amateur female futsal players.

RESUMEN

BACKGROUND: Despite bone marrow (BM) immunophenotyping by flow cytometry has progressively been recognized as an important tool for the diagnosis of myelodysplastic syndromes (MDS), the sparse knowledge about normal erythroid maturation and the lack of markers for erythroid characterization is a major shortcoming. METHODS: Here, we analyzed the expression of CD43 and CD49d, two markers included in the diagnostic panel for B-cell chronic lymphoproliferative disorders (B-CLPD), in the CD34+ compartment of normal BM and along the normal and dysplastic erythroid maturation. For this, 13 normal BM aspirates and 18 BM aspirates from MDS patients were studied by flow cytometry. RESULTS: Normal BM presented a higher expression of CD43 and CD49d among CD34+ erythroid precursors, compared to CD34+ cells committed to the remaining hematopoietic cell lineages. CD43 expression progressively decreased along the normal erythroid maturation, whereas CD49d levels increased from Stage I to Stage II, were maintained in Stages II and III, and then decreased until the last stage of maturation. In MDS, the expression of CD43 and CD49d followed a similar pattern, but with decreased expression levels for both markers, observed in all erythroid maturation stages (P < 0.05). CONCLUSIONS: Our results point to the usefulness of CD43 and CD49d, two markers commonly present in B-CLPD diagnosis panels, in the identification of dysplastic phenotypic features in the erythroid lineage. This allows a feasible and inexpensive way to identify patients who would benefit from a more extensive study to evaluate the presence of MDS, during the processing of suspected B-CLPD samples. © 2019 International Clinical Cytometry Society.

RESUMEN

The prevalence of gastrointestinal disorders, such as constipation, has been increasing. Genetic factors and lifestyle are some of the etiologies of this issue, affecting the health of the population. Natural products have properties that contribute to health maintenance and health promotion, including reduction of the inflammatory process. Hancornia speciosa, popularly known as mangaba, is an abundant and native fruit in the Brazilian Cerrado, commercialized for culinary purposes and used because of its pharmacological properties. The objective of this study was to evaluate if the supplementation of different concentrations of mangaba pulp can improve intestinal motility and bowel health in Wistar rats. Forty male rats were divided into five groups. The experiment lasted 14 days and the groups were tested with water, industrialized laxative jelly made from tamarind as medication, or mangaba at 5, 10, and 15 mL/kg of body weight. Food intake, weight gain, ion balance, intestinal motility, and histopathological analysis of the small intestine, large intestine, and liver were evaluated. Supplementation of mangaba pulp at its highest concentration (15 mL/kg body weight) caused a 15% increase in the distance traveled by the charcoal meal, and a decrease in serum magnesium levels and white cells in both the small and large intestines. The results suggest that mangaba pulp presents laxative, anti-inflammatory properties and that its consumption is beneficial and should be encouraged.

RESUMEN

To learn about and understand the feelings experienced by nursing students when making bandages during curricular and extracurricular clinical practice. This is a qualitative study, with a phenomenological framework. The guiding question used was: What did you feel while making the bandage? This study revealed that nursing students feel unprepared for making bandages. Students also reported various difficulties; like touching a stranger and associating theory to practice, for instance. They experienced positive emotions, like pleasure, as well as negative feelings, such as distress, insecurity, fear, and embarrassment. We believe that the teacher-student relationship would be improved if a space is created to discuss these experiences. In fact, such as space would represent one form of support, which students need due to the difficulties they have to deal with in this period of their academic education.

RESUMEN

In this report, we report a case study on a 50-year-old male patient with different chronic wounds, such as venous ulcer and arterial ulcer in both legs. These wounds have persisted for more than 10 years, despite the different treatments applied, including, different dressings, hyperbaric camera, as well as the used of several medicines of oral and topical application. The case is addressed with the aim to evaluate if treatment that uses combined techniques such as low level laser therapy (LLLT), photodynamic therapy and cellulose membrane is able to improve healing and reduction of time of treatment in those types of chronic wounds. The results show the clinical protocol is effective for the healing of arterial and venous ulcers and can be considered as a promising possibility.

RESUMEN

Introdução: As úlceras de difícil cicatrização caracterizam-se como uma patologia que afeta cerca de 20 milhões de pessoas pelo mundo. A terapia fotodinâmica TFD é um método que atua nas fases da cicatrização, bioestimulando o tecido e promovendo a morte dos microorganismos Objetivo: O objetivo deste estudo foi avaliar a TFD como técnica de ação bactericida na cicatrização das úlceras de usuários de um serviço público de saúde acometidos por úlceras venosas UV. Métodos: Para avaliar a presença de bactérias nas úlceras, foi utilizado um swab stuart. Foi aplicado o medicamento à base de curcumina na úlcera e a mesma foi imediatamente ocluída com papel alumínio durante 20 minutos. Resultados: Durante todo período de coleta houve crescimento de bactérias nas úlceras. Os participantes obtiveram redução da área das úlceras, avaliadas pela quantificação do software Image J Conclusão: A TFD foi capaz de acelerar o tempo de cicatrização de úlceras venosas, ao efeito bactericida, a técnica carece ainda de mais estudos.


Introduction: Ulcers that are difficult to heal are characterized as a pathology that affects about 20 million people around the world. PDT photodynamic therapy is a method that acts in the healing phases, biostimulating the tissue and promoting the death of microorganisms affected by UV. Methods: To assess the presence of bacteria in the ulcers, a stuart swab was used. the medicine based on curcumin was applied to the ulcer and it was immediately occluded with aluminum foil for 20 minutes. Results: During the entire collection period, there was growth of bacteria in the ulcers. The participants obtained a reduction in the area of the ulcers, evaluated by the quantification of the Image J software. Conclusion: PDT was able to accelerate the healing time of venous ulcers, due to its bactericidal effect, the technique still needs further studies.
