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

Aspectos clínicos e macroscópicos da palatoplastia imediata com implante de cartilagem da pina articular, conservada em glicerina a 98%, após indução experimental de fenda palatina em cães Clinic and macroscopic view of immediate palatoplasty with auricular pinna cartilage preserved in 98% glycerin in canine experimental palat cleft

Os defeitos de espessura completa do palato que resultam em comunicação oro-nasal raramente cicatrizam espontaneamente. Eles requerem reparo cirúrgico, porém, pode ser difícil obter cicatrização satisfatória devido às condições próprias das cavidades nasal e oral. Neste experimento, foram utilizados 14 cães, reunidos em dois grupos de igual número. Todos animais foram submetidos à indução de fenda palatina experimental. O grupo G1 foi o controle, cuja palatoplastia foi realizada a partir da confecção de "flap" muco-periósteo. No grupo G2, foi utilizada cartilagem da pina auricular conservada em glicerina a 98% entre o osso palatino e o muco-periósteo. Os animais foram avaliados macroscopicamente quanto ao processo cicatricial, por radiografias para a regeneração óssea e por rinoscopia para observar a regeneração da mucosa nasal. Foi observada a cicatrização da mucosa oral a partir do 10&ordm; dia, com deiscência de sutura em dois animais do grupo G1. A radiografia demonstrou evolução na cicatrização óssea, num processo mais acelerado no grupo G2 quando comparado ao grupo G1. A rinoscopia revelou, aos 60 dias, completa regeneração da mucosa nasal em ambos os grupos. Ao final do período de avaliação foi observada macroscopicamente, completa fusão óssea nos animais do grupo G2 e incompleta nos do grupo G1, o que demonstrou a interferência benéfica do implante no processo cicatricial do grupo G2.<br>The incomplete defects of hard palate result in oro-nasal fistula seldom cure themselves in a spontaneous way, due to limited condition in oral and nasal cavity it may be difficult to obtain satisfactory cicatrization, requiring surgery to interfere in the healing process. Fourteen dogs arranged in two groups were submitted to experimental hard palate cleft. The G1 group was the control group, in which palatoplasty was achieved with mucous-periosteum flap. In the G2 group, a preserved at 98% glycerin auricular pinna cartilage was used between the palate bone and mucous-periosteum. The mucosal healing and bone regeneration were evaluated, radiographied and the nasal mucosa was observed by rhinoscopy. The oral mucosa heal was observed at the tenth day, but the suture dehiscence occurred in two dogs from the G1 group. The radiography evaluation demonstrated bone regeneration evolution quicker in the G2 group, than in the G1 group. The complete nasal mucous regeneration was demonstrated by rhinoscopy at the sixtieth day. The conclusive evaluation observed full bone union in the G2 group and unachieved bone union in the G1 group, which showed graft interference in the G2 group bone regeneration

Implementation of a Brazilian Cardioprotective Nutritional (BALANCE) Program for improvement on quality of diet and secondary prevention of cardiovascular events: A randomized, multicenter trial

Background: Appropriate dietary recommendations represent a key part of secondary prevention in cardiovascular disease (CVD). We evaluated the effectiveness of the implementation of a nutritional program on quality of diet, cardiovascular events, and death in patients with established CVD. Methods: In this open-label, multicenter trial conducted in 35 sites in Brazil, we randomly assigned (1:1) patients aged 45 years or older to receive either the BALANCE Program (experimental group) or conventional nutrition advice (control group). The BALANCE Program included a unique nutritional education strategy to implement recommendations from guidelines, adapted to the use of affordable and regional foods. Adherence to diet was evaluated by the modified Alternative Healthy Eating Index. The primary end point was a composite of all-cause mortality, cardiovascular death, cardiac arrest, myocardial infarction, stroke, myocardial revascularization, amputation, or hospitalization for unstable angina. Secondary end points included biochemical and anthropometric data, and blood pressure levels. Results: From March 5, 2013, to Abril 7, 2015, a total of 2534 eligible patients were randomly assigned to either the BALANCE Program group (n = 1,266) or the control group (n = 1,268) and were followed up for a median of 3.5 years. In total, 235 (9.3%) participants had been lost to follow-up. After 3 years of follow-up, mean modified Alternative Healthy Eating Index (scale 0-70) was only slightly higher in the BALANCE group versus the control group (26.2 ± 8.4 vs 24.7 ± 8.6, P <.01), mainly due to a 0.5-serving/d greater intake of fruits and of vegetables in the BALANCE group. Primary end point events occurred in 236 participants (18.8%) in the BALANCE group and in 207 participants (16.4%) in the control group (hazard ratio, 1.15; 95% CI 0.95-1.38; P =.15). Secondary end points did not differ between groups after follow-up. Conclusions: The BALANCE Program only slightly improved adherence to a healthy diet in patients with established CVD and had no significant effect on the incidence of cardiovascular events or death. © 2019 The Author

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
