Resumo Este artigo discute questões relativas às diversas iniciativas de plataformização do trabalho docente no contexto atual. O trabalho consiste num esforço empírico de localização e cotejamento de plataformas digitais de ensino, propondo, também, uma análise crítica sustentada por corpo bibliográfico e analítico pertinente. O principal objetivo é indicar, por meio de uma análise sistematizada, como podem se operar, via plataformas digitais de ensino, o sequestro e a precarização do trabalho docente, dissimulado por uma semântica neoliberal que busca conferir edulcoradas associações de sentido idiomático (autonomia, empreendedorismo, etc.) a um processo em que aqueles que trabalham para ou sob o controle das plataformas digitais acabam sendo prejudicados. atual ensino propondo também pertinente indicar sistematizada operar autonomia, autonomia (autonomia empreendedorismo etc. etc prejudicados
Abstract This article discusses issues related to various initiatives for the platformization of teaching work in the current context. The study consists of an empirical effort to locate and compare digital teaching platforms, and proposes a critical analysis supported by a relevant bibliographic and analytical body. The main objective is to show, through a systematized analysis, how the kidnapping and precarization of teaching work via digital teaching platforms can occur. These operations are concealed by a neoliberal semantics that seeks to confer soothed idiomatic meaning associations (autonomy, entrepreneurship etc.) on a process in which those who work for or under the control of digital platforms end up being harmed. context body show occur autonomy, autonomy (autonomy etc. etc harmed

ABSTRACT Sporotrichosis is caused by fungi belonging to the genus Sporothrix, and is generally acquired by traumatic inoculation. A 26-year-old man developed pustular lesions and a 6-kg weight loss after developing a lesion on his right hand 6 months previously. He was diagnosed with acquired human immunodeficiency syndrome (AIDS) and disseminated sporotrichosis cultures of bone and muscle biopsy and blood samples grew Sporothrix schenckii. The patient underwent reconstructive surgery and 9 months of treatment with amphotericin B and itraconazole, and showed complete wound healing and improved hand functionality. Suspicion of the disease is necessary in immunosuppressed patients living in endemic areas. inoculation 26yearold yearold 26 year old 6kg kg previously AIDS (AIDS schenckii itraconazole functionality areas 2

BACKGROUND In response to the coronavirus disease 2019 (Covid-19) pandemic, Brazil authorised the Astra Zeneca/Fiocruz vaccine in January 2021. As the Delta variant emerged in May 2021, interval between vaccine doses was adjusted. By September 2021, the Brazilian National Immunisation Program recommended a booster dose for individuals over 70, and later expanded the recommendation to all adults. OBJECTIVES Assess the equivalence of IgG antibody response against the Covid-19 S protein before and approximately 28 days after the third dose of a Covid-19 recombinant vaccine. Two groups received initial two doses with intervals of eight and 12 weeks. METHODS This is a phase IV clinical study, uncontrolled, non-randomised. The study proposes calculating the ratio of geometric means titres (GMT) 28 days after the third dose, with a target ratio of confidence interval (CI) between 0.77 and 1.3. FINDINGS In the primary endpoint, there was no equivalence between the eight- and 12-week intervals with a slight variation favouring the eight-week group. Post-third dose, both groups showed increases titres at 28 days, three months, six months and 12 months. Both groups responded similarly to Delta and Omicron BA.1, with a more significant increase for Delta. MAIN CONCLUSIONS The study showed strong and consistent immune response in all age groups receiving the Covid-19 recombinant vaccine. Third dose elicited an increase in GMT by at least three times aligned with Ministry of Health strategies emphasising Bio-Manguinhos crucial role in pandemic control in the country. 201 Covid19 Covid 19 (Covid-19 ZenecaFiocruz Zeneca Fiocruz 2021 adjusted 70 adults Covid-1 2 1 weeks uncontrolled nonrandomised. nonrandomised non randomised. randomised non-randomised (GMT CI (CI 077 0 77 0.7 13 3 1.3 endpoint 12week week eightweek group Postthird Post BA1 BA BA.1 BioManguinhos Bio Manguinhos country 20 Covid1 (Covid-1 202 7 Covid- 07 0. 1.

RESUMO Objetivo: Pacientes com insuficiência respiratória aguda frequentemente necessitam de ventilação mecânica para reduzir o trabalho respiratório e melhorar a troca gasosa; no entanto, a ventilação mecânica pode exacerbar a lesão pulmonar. As estratégias de ventilação protetora, caracterizadas por baixo volume corrente (≤ 8mL/kg de peso corporal previsto) e pressão de platô limitada abaixo de 30cmH2O, mostraram melhores desfechos em pacientes com síndrome do desconforto respiratório agudo. No entanto, na transição para a ventilação espontânea, manter o volume corrente dentro dos níveis de proteção pode ser desafiador, e não está claro se o volume corrente baixo durante a ventilação espontânea afeta os desfechos dos pacientes. Desenvolvemos um protocolo de estudo para estimar a prevalência de ventilação com volume corrente baixo nas primeiras 24 horas de ventilação espontânea em pacientes com insuficiência respiratória aguda hipoxêmica e sua associação com dias livres da ventilação mecânica e sobrevida. Métodos: Desenhamos um estudo de coorte multicêntrico, multinacional, com seguimento de 28 dias, que incluirá pacientes com insuficiência respiratória aguda, definida como pressão parcial de oxigênio/fração inspirada de oxigênio < 300mmHg, em transição para ventilação espontânea em unidades de terapia intensiva na América Latina. Resultados: Pretendemos incluir 422 pacientes em 10 países. Os desfechos primários são a prevalência de baixo volume corrente nas primeiras 24 horas de ventilação espontânea e dias livres da ventilação mecânica no dia 28. Os desfechos secundários são mortalidade hospitalar e na unidade de terapia intensiva, incidência de assincronia e retorno à ventilação controlada e sedação. Conclusão: Neste estudo, avaliaremos a prevalência de volume corrente baixo durante a ventilação espontânea e sua associação com os desfechos clínicos, o que pode informar a prática clínica e futuros ensaios clínicos.

ABSTRACT Objective: Patients with acute respiratory failure often require mechanical ventilation to reduce the work of breathing and improve gas exchange; however, this may exacerbate lung injury. Protective ventilation strategies, characterized by low tidal volumes (≤ 8mL/kg of predicted body weight) and limited plateau pressure below 30cmH2O, have shown improved outcomes in patients with acute respiratory distress syndrome. However, in the transition to spontaneous ventilation, it can be challenging to maintain tidal volume within protective levels, and it is unclear whether low tidal volumes during spontaneous ventilation impact patient outcomes. We developed a study protocol to estimate the prevalence of low tidal volume ventilation in the first 24 hours of spontaneous ventilation in patients with hypoxemic acute respiratory failure and its association with ventilator-free days and survival. Methods: We designed a multicenter, multinational, cohort study with a 28-day follow-up that will include patients with acute respiratory failure, defined as a partial oxygen pressure/fraction of inspired oxygen ratio < 300mmHg, in transition to spontaneous ventilation in intensive care units in Latin America. Results: We plan to include 422 patients in ten countries. The primary outcomes are the prevalence of low tidal volume in the first 24 hours of spontaneous ventilation and ventilator-free days on day 28. The secondary outcomes are intensive care unit and hospital mortality, incidence of asynchrony and return to controlled ventilation and sedation. Conclusion: In this study, we will assess the prevalence of low tidal volume during spontaneous ventilation and its association with clinical outcomes, which can inform clinical practice and future clinical trials.

ABSTRACT Rationale: Evidence about long-term sequelae after hospitalization for acute respiratory distress syndrome due to COVID-19 is still scarce. Purpose: To evaluate changes in pulmonary, cardiac, and renal function and in quality of life after hospitalization for acute respiratory distress syndrome secondary to COVID-19. Methods: This will be a multicenter case–control study of 220 participants. Eligible are patients who are hospitalized for acute respiratory distress syndrome due to COVID-19. In the control group, individuals with no history of hospitalization in the last 12 months or long-term symptoms of COVID-19 will be selected. All individuals will be subjected to pulmonary spirometry with a carbon monoxide diffusion test, chest tomography, cardiac and renal magnetic resonance imaging with gadolinium, ergospirometry, serum and urinary creatinine, total protein, and urinary microalbuminuria, in addition to quality-of-life questionnaires. Patients will be evaluated 12 months after hospital discharge, and controls will be evaluated within 90 days of inclusion in the study. For all the statistical analyses, p < 0.05 is the threshold for significance. Results: The primary outcome of the study will be the pulmonary diffusing capacity for carbon monoxide measured after 12 months. The other parameters of pulmonary, cardiac, and renal function and quality of life are secondary outcomes. Conclusion: This study aims to determine the long-term sequelae of pulmonary, cardiac, and renal function and the quality of life of patients hospitalized for acute respiratory distress syndrome due to COVID-19 in the Brazilian population.

SUMMARY OBJECTIVE: The aim of this study was to evaluate the efficacy of long-term oxygen therapy as a strategy to reduce hospitalization time in patients affected by COVID-19. METHODS: Between April and December 2021, COVID-19 patients with stable clinical conditions needing supplementary oxygen therapy during hospitalization were oriented to have hospital discharge with long-term oxygen therapy and reassessment after 15 days. RESULTS: A total of 62 patients were evaluated and, 15 days after discharge, 69% of patients had suspended long-term oxygen therapy, with no difference between the groups admitted to the intensive care unit or the ward (p=0.319). Among the individuals who needed to maintain long-term oxygen therapy, in addition to worse P/F ratio (265±57 vs. 345±51; p<0.001) and lower partial pressure of oxygen (55±12 vs. 72±11 mmHg; p<0.001), were those more obese (37±8 vs. 30±6 kg/m2; p=0.032), needed more time for invasive mechanical ventilation (46±27 vs. 20±16 days; p=0.029), had greater persistence of symptoms (p<0.001), and shorter time between the onset of symptoms and the need for hospitalization (7 [2–9] vs. 10 [6–12] days; p=0.039). CONCLUSION: Long-term oxygen therapy is an effective strategy for reducing hospitalization time in COVID-19 patients, regardless of gravity. Additionally, more obese patients with persistence of respiratory symptoms, faster disease evolution, and more days of invasive mechanical ventilation needed to maintain the long-term oxygen therapy longer.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Abstract Plants synthesize secondary metabolites as a means of survival and competition. These metabolites are a potential source of natural antioxidants that may promote activity, favoring the control of cellular damage caused by oxidative stress. The Annonaceae family occurs in tropical and subtropical regions worldwide. The medicinal benefits of plants from this family are caused by secondary metabolites present in these species. Thus, this study aimed to determine the total phenolic content, evaluate the antioxidant potential, and in vitro cytotoxicity of the leaf ethanolic extract from Ephedrantus amazonicus R. E. Fries. The phenolic content and antioxidant activity were evaluated by the Folin-Ciocalteu and DPPH methods, respectively. The assays were adapted for 96-well microplates, with absorbance reading at λ = 630 and 517 nm, respectively, using a UV-Vis spectrophotometer. The in vitro cytotoxicity assay was performed using fibroblasts (L929 cell line). The MS/MS analyses were performed through direct infusion using a LCQ Fleet mass spectrometer equipped with APCI font and ion trap analyzer, in the positive and negative mode. A molecular network was created using the online workflow on the GNPS website (http://gnps.ucsd.edu). The phenolic content at 400μg was 25.24 ± 0.98μg.GAE/g, while the antioxidant activity showed an EC50 of 13.37±2.63 μg.mL-1. Dereplication led to the annotation of three flavonoids that may contribute to the observed antioxidant activity. The extract showed low cytotoxicity at the highest tested concentration (> 500μM). The results demonstrate that the extract from Ephedrantus amazonicus R.E. Fries leaves is a promising source of natural antioxidants. competition stress worldwide species Thus R E FolinCiocalteu Folin Ciocalteu methods respectively 96well well 96 microplates 63 51 nm UVVis UV Vis spectrophotometer L929 L (L92 line. line . line) MSMS MS analyzer mode http//gnps.ucsd.edu. httpgnpsucsdedu http //gnps.ucsd.edu gnps ucsd edu (http://gnps.ucsd.edu) μg 2524 25 24 25.2 098μgGAEg μgGAEg 0 98μg GAE g 0.98μg.GAE/g EC EC5 1337263 13 37 2 13.37±2.6 μg.mL1. μgmL1 μgmL μg.mL 1. mL 1 μg.mL-1 > ( 500μM. 500μM μM 500μM) RE R.E 9 6 5 L92 (L9 http//gnps.ucsd.edu gnpsucsdedu (http://gnps.ucsd.edu 252 25. 133726 3 13.37±2. mL1 μg.mL1 μg.mL- L9 (L 13372 13.37±2 1337 13.37± 133 13.37 13.3 13.

RESUMO Diante da cronificação da infecção pelo HIV, fatores psicossociais surgem como potencializadores para elevação dos níveis de estresse nas PVHIV, bem como para o desequilíbrio imunológico e elevação da carga viral. O objetivo da presente pesquisa foi avaliar o nível de estresse, a contagem de linfócitos TCD4 + e a carga viral de pessoas vivendo com HIV submetidas a TARV, atendidas em um hospital público universitário. Tratou-se de um estudo observacional, transversal com 25 pacientes (40,76 anos± 9,88 anos) que vivem com HIV atendidos no ambulatório de um hospital público do Rio de Janeiro. Foi utilizado um questionário sociodemográfico para caracterização da amostra, o estresse foi avaliado através do Inventário de Sintomas de Stress de LIPP e observados exames laboratoriais recentes. Foi identificado estresse em 68% dos participantes, com predomínio de sintomas físicos e fase de resistência. Houve maior prevalência de estresse em pessoas com baixo nível socioeconômico, desemprego e diagnóstico recente. Não foram observados menores níveis de linfócitos TCD4 + ou maior carga viral nas pessoas com estresse.
ABSTRACT Given the chronicity of HIV infection, psychosocial factors emerge as potentiators for the elevation of stress levels in PLHIV, as well as for the immunological imbalance and elevation of the viral load. The present research objective was to evaluate the stress level, TCD4+ lymphocyte count and viral load of people living with HIV undergoing ART, treated at a public university hospital. This was an observational, cross-sectional research with 25 patients (40.76 years± 9.88 years) living with HIV treated at the outpatient clinic of a public hospital in Rio de Janeiro. A sociodemographic questionnaire was used to characterise the sample. Stress was evaluated through the LIPP Stress Symptom Inventory and observed in recent laboratory tests. Stress was identified in 68% of the participants, with a predominance of physical symptoms and a resistance phase. There was a higher prevalence of stress in people with low socioeconomic status, unemployment and recent diagnosis. Lower levels of CD4+ T lymphocytes or higher viral load were not observed in people with stress.

Layered double hydroxides (LDH) with the composition Zn2Cr, intercalated with acetate and chloride ions were synthesized by co-precipitation with increasing pH and characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and inductively coupled plasma-optical emission spectrometry (ICP-OES). The samples synthesized at optimized pH showed XRD patterns with basal diffraction peaks typical of layered structures, with basal distances of 7.88 and 12.69 Å for intercalated chloride (Zn2Cr/Cl) and acetate (Zn2Cr/Ac), respectively. After optimization experiments, exchange reactions were performed with different anions, using an excess of five times the anions to be intercalated. Zn2Cr/Cl was exchanged with CH3COO-, F-, Br-, I-, SO42- and NO3-, and Zn2Cr/Ac was exchanged with F-, Cl-, Br-, I-, SO42- and NO3-. Not all reactions were effective, indicating that among the evaluated anions, CH3COO- was preferred for exchange, mainly attributed to the pre-expansion with bigger anions, facilitating the exchange with smaller anions.

Boron-manganese steel 22MnB5 is extensively used in structural automotive components. Knowledge about its microstructural evolution during hot stamping and resistance spot welding (RSW) is extremely relevant to guarantee compliance with application requirements. Particularly, corrosion properties are critical to the application of uncoated sheet steels. However, microstructural studies are usually simplified to top-hat geometries, which might not be fully representative of the complex thermomechanical cycles locally faced by a real component. Therefore, the present work brings an extensive characterization of a hot-stamped 22MnB5 automotive B-pillar in terms of microstructure, hardness and corrosion resistance, which were correlated with a reverse engineering of the process using numerical simulation. Physical simulations of the subcritical heat affected zone (SCHAZ) of RSW were done to assess the influence of microstructure on martensite tempering. Results showed that the component undergoes a complex strain distribution along its body during hot stamping. Most heavily strained regions presented higher amounts of ferrite, leading to poorer corrosion resistance, since ferrite behaves as an anode. Physical simulations of the SCHAZ showed that the softening degree due to martensite tempering is solely affected by peak temperature, while other microstructural features appear to exert negligible or no influence.

Resumo Toda atividade que atua envolvendo a exploração de recursos naturais, como a pesca, precisa ser organizada e conduzida com base nas informações dos programas de monitoramento para permitir uma avaliação contínua. Com o aumento da pressão pesqueira no Brasil, o entendimento da importância dos programas de monitoramento da pesca e como eles podem informar e auxiliar na tomada de decisões de conservação permanece limitado. Com base na literatura sobre pesca e conservação participativa, chamamos a atenção para a necessidade de gerar informações sobre o setor pesqueiro nacional para melhorar a pesca no país. Dado o contexto da necessidade de gerar informações sobre os estoques pesqueiros em exploração, bem como identificar potenciais alternativas de pesca e realizar diversas análises setoriais em conformidade com a Agenda 2030 para o Desenvolvimento Sustentável, é apresentada e discutida no presente trabalho a falta de um sistema de monitoramento contínuo da pesca no Brasil e seus efeitos na sustentabilidade da pesca no país. naturais contínua limitado participativa país 203 Sustentável 20 2
Abstract Every activity that involves exploitation of natural resources, such as fishing, needs to be organized and conducted based on information from monitoring programs to allow continuous evaluation. With the increasing fishing pressure in Brazil, the understanding of the importance of fisheries monitoring programs and how they can inform and assist in conservation decision-making remains limited. Based on the literature on fisheries and participatory conservation, we call attention to the need to generate information on the national fisheries sector in order to improve fisheries in the country. Given the context of the need to generate information on fishing stocks under exploitation, as well as to identify potential alternative fisheries and carry out various sectoral analyses in compliance with the 2030 Agenda for Sustainable Development, we present and discuss in the present paper the lack of a system of continuous fishing monitoring in Brazil and its effects on the fisheries sustainability in the country. resources evaluation decisionmaking decision making limited country 203 Development 20 2

Spent Foundry Sand is one of the largest industrial solid wastes generated by foundries in the production of iron and steel components. Currently, millions of tons of molten sands are discarded worldwide. Therefore, this work aims to reuse the Spent Foundry Sand for the production of glass-ceramic materials, since this reuse minimizes the environmental impacts related to its discarding. The Spent Foundry Sand, composed of >60% SiO2, was mixed with limestone and melted at 1500 °C to produce the glass (melting and rapid cooling method). The materials were characterized by X-Ray Fluorescence, X-Ray Diffraction and thermal analysis. The X-Ray Diffraction results of the glass tablets treated at 875, 941 and 1050 °C show that the formed phases are Wollastonite-1A, β-Wollastonite and Akermanite. In summary, it is possible to produce glass-ceramic from Spent Foundry Sand with Wollastonite phase. components Currently worldwide Therefore glassceramic ceramic discarding 60 >60 SiO2 SiO 150 C melting method. method . method) XRay X Ray Fluorescence analysis 875 94 105 Wollastonite1A, Wollastonite1A WollastoniteA 1A, 1A A Wollastonite-1A βWollastonite β Akermanite summary phase 6 >6 15 87 9 10 > 1 8

Abstract The aim of this study was to describe the prevalence, clinicopathological, and prognostic features of acinic cell carcinoma (AciCC) of the oral and maxillofacial region. AciCC cases were retrospectively retrieved from 11 pathology centers of three different countries. Medical records were examined to extract demographic, clinical, pathologic, and follow-up information. A total of 75 cases were included. Females (65.33%) with a mean age of 45.51 years were mostly affected. The lesions usually presented as an asymptomatic (64.28%) nodule (95.66%) in the parotid gland (70.68%). The association of two histopathological patterns was the most common finding (48.93%) and the tumors presented mainly conventional histopathological grades (86.11%). Surgical treatment was performed in the majority of the cases (59.19%). Local recurrence was observed in 20% of the informed cases, regional metastasis in 30.43%, and distant metastasis in 12.50%. The statistical analysis showed that the cases with a solid histopathological pattern (p=0.01), high-grade transformation (p=0.008), recurrence (p=0.007), and regional metastasis (p=0.03) were associated with poor survival. In conclusion, high histopathological transformation, presence of nodal metastasis, and recurrence were prognostic factors for AciCC of the oral and maxillofacial region. prevalence clinicopathological (AciCC region 1 countries demographic clinical pathologic followup follow up information 7 included 65.33% 6533 65 33 (65.33% 4551 45 51 45.5 affected 64.28% 6428 64 28 (64.28% 95.66% 9566 95 66 (95.66% 70.68%. 7068 70.68% . 70 68 (70.68%) 48.93% 4893 48 93 (48.93% 86.11%. 8611 86.11% 86 (86.11%) 59.19%. 5919 59.19% 59 19 (59.19%) 20 3043 30 43 30.43% 1250 12 50 12.50% p=0.01, p001 p p=0.01 , 0 01 (p=0.01) highgrade grade p=0.008, p0008 p=0.008 008 (p=0.008) p=0.007, p0007 p=0.007 007 (p=0.007) p=0.03 p003 03 (p=0.03 survival conclusion 65.33 653 6 3 (65.33 455 4 5 45. 64.28 642 2 (64.28 95.66 956 9 (95.66 706 70.68 (70.68% 48.93 489 (48.93 861 86.11 8 (86.11% 591 59.19 (59.19% 304 30.43 125 12.50 p00 p=0.0 (p=0.01 p000 p=0.00 00 (p=0.008 (p=0.007 (p=0.0 65.3 (65.3 64.2 (64.2 95.6 (95.6 70.6 (70.68 48.9 (48.9 86.1 (86.11 59.1 (59.19 30.4 12.5 p0 p=0.
