ABSTRACT: Dental abscess in ruminants is an acute polymicrobial infection, usually resulting from periodontal disease or endodontic infection, with consequences for animal health and welfare. The present study aimed to describe the bacterial microbiota of dental abscesses in Blastocerus dichotomus. Biological material from mandibular dental abscesses, punctured with a sterile syringe and needle during routine veterinary curative procedures or necropsies, was collected from three ex-situ marsh deer. Bacteria were identified using high-throughput sequencing of the 16S ribosomal RNA gene. The three specimens had the presence of facial bulging, and two died because of severe emaciation with a history of progressive weight loss. Bacteroides (38.6%), Fusobacterium (36.65%), and Porphyromonas (7.49%) represented the most abundant genera and Fusobacterium necrophorum (35.69%), Porphyromonas levii (3.12%) and Porphyromonas gulae (1.78%) were among the ten most represented species in the microbiota of mandibular abscess in Blastocerus dichotomus. These molecular findings demonstrate a broader diversity of species in the polymicrobial nature of dental abscesses in B. dichotomus than was previously reported when culture-dependent methods were used in the diagnosis.

RESUMO: O abcesso dentário em ruminantes é uma infeção polimicrobiana aguda, geralmente resultante de doença periodontal ou infeção endodôntica, com consequências para a saúde e bem-estar animal. O presente estudo teve como objetivo descrever a microbiota bacteriana de abscessos dentários em Blastocerus dichotomus. Material biológico de abscessos dentários mandibulares, puncionados com seringa e agulha estéril durante procedimentos curativos veterinários de rotina ou necropsias, foi coletado de três cervos do pantanal criados ex situ. As bactérias foram identificadas usando sequenciamento de alto rendimento do gene 16S ribossomal RNA. Os três espécimes apresentavam abaulamento facial e dois faleceram por emagrecimento severo com histórico de emagrecimento progressivo. Bacteroides (38,6%), Fusobacterium (36,65%) e Porphyromonas (7,49%) representaram os gêneros mais abundantes e Fusobacterium necrophorum (35,69%), Porphyromonas levii (3,12%) e Porphyromonas gulae (1,78%) estavam entre as dez espécies mais representadas na microbiota do abscesso mandibular em Blastocerus dichotomus. Esses achados moleculares demonstram uma diversidade mais ampla de espécies na natureza polimicrobiana dos abscessos dentários em B. dichotomus, do que o relatado anteriormente quando métodos dependentes de cultura foram utilizados no diagnóstico.

In this work, a low-cost automatic weather station was developed using reused materials and low-cost sensors, connected to the Ubidots data visualization and management website. The station has sensors for temperature (AHT10), humidity (AHT10), pressure (BMP180), solar radiation (LDR), a rain gauge and a digital anemometer, both made with reused and easily accessible materials, the anemometer being developed with a fan (hall sensor) and the rain gauge based on a reed switch magnetic sensor. The entire system is connected to the ESP8266 electronic prototyping board, which already has a module that allows connection to the internet. The entire device cost around 50 R$. The temperature and humidity sensors and anemometer were calibrated using standard sensors to ensure accurate measurement. Humidity and temperature values were then compared to data obtained from a nearby standard weather station. The rain gauge also underwent calibration to measure the amount of rain in millimeters. Additionally, model-based forecasts were implemented to estimate dew point, water vapor pressure, precipitable water, and wind chill, providing additional information about local weather conditions. work lowcost low website AHT10, AHT10 AHT , (AHT10) BMP180, BMP180 BMP (BMP180) LDR, LDR (LDR) hall sensor ESP ESP826 board internet 5 R R$ measurement millimeters Additionally modelbased model point chill conditions AHT1 (AHT10 BMP18 (BMP180 (LDR ESP82 (AHT1 BMP1 (BMP18 ESP8 (AHT (BMP1 (BMP

Pesticides have been pointed out as hormone disruptors and may significantly affect the prognosis of hormone-dependent diseases such as breast cancer (BC). Here, we investigated the impact of occupational pesticide exposure on systemic cortisol levels in female rural workers diagnosed with BC. Occupational exposure was assessed by interviews with a standardized questionnaire. Plasma samples (112 from pesticide-exposed women and 77 from unexposed women) were collected in the afternoon, outside the physiological cortisol peak, and analyzed by a chemiluminescent paramagnetic immunoassay for the quantitative determination of cortisol levels in serum and plasma. The results from both groups were categorized according to patients' clinicopathological and exposure data. BC pesticide-exposed women presented higher levels of cortisol than the unexposed. Higher cortisol levels were also detected in the exposed group with more aggressive disease (triple-negative BC), with tumors over 2 cm, with lymph node metastases, and with high risk of disease recurrence and death. These findings demonstrated that there is an association between pesticide exposure and BC that affected cortisol levels and correlated to poor disease prognosis. hormonedependent dependent .

RESUMO O presente estudo teve por objetivo descrever os efeitos da estabulação sobre características termográficas dos membros de equinos adultos, para comparar o nível de bem-estar entre cavalos mantidos soltos e aqueles sob estabulação contínua e para investigar se a Termografia Infravermelha (TIV) pode ser uma ferramenta efetiva na avaliação do bem-estar em equinos. 24 cavalos machos castrados da raça Brasileiro de Hipismo, com idade entre 5 e 9 anos e peso de 500 ± 50kg foram utilizados em um experimento de 6 semanas de duração. Os animais foram divididos em 2 grupos: 1) Pasto - animais mantidos em piquetes e utilizados exclusivamente em patrulhas urbanas; 2) Baia - animais utilizados exclusivamente em patrulhas urbanas, mas mantidos em estabulação contínua, em cocheiras de 12m² de concreto sem cama. Todos os animais foram avaliados uma vez por semana durante 6 semanas. O comportamento animal, a temperatura dos olhos e extremidades distais bem como amostras de sangue, foram colhidos. Os cavalos estabulados apresentaram comportamento estereotipado e maior concentração sérica de cortisol, indicando menor grau de bem-estar quando comparados aos animais manejados soltos em piquetes. A termografia dos membros apresentou potencial para identificar estresse crônico em cavalos uma vez que a análise discriminante mostrou 74,5% de acerto preditivo enquanto a temperatura máxima do olho não foi eficiente para esse propósito. adultos bemestar estar TIV (TIV Hipismo 50 kg duração grupos 1 urbanas m 12m cama animal sangue colhidos cortisol 745 74 74,5 propósito 7 74,

ABSTRACT This study aims to describe the effects of stabling on thermographic characteristics of adult equine limbs, to compare the level of animal welfare between horses kept loose and those under continuous stabling and to investigate whether the Infrared Thermography (IRT) can be an effective tool to evaluate the welfare of equines. 24 gelding horses of Brazilian Sport Horse breed, aged between 5 and 9 years and weighing 500 ± 50kg were used in a 6-week trial. They were divided into 2 groups: 1) Paddock - equines kept in paddocks and ridden exclusively on urban patrol; 2) Stall - animals that ridden exclusively on urban patrol, but were kept in continuous stabling, housed in 12m² with concrete and bedless stables. Every animal was evaluated once a week over six weeks. Animal behavior and temperature of the eyes and distal extremities of the limbs as well as blood samples were collected. The confined horses showed stereotyped behavior and higher serum cortisol, indicating lower animal welfare when compared to those managed in a pasture. Limb IRT showed predictive potential for identifying chronic stress as the discriminating analysis showed 74.5% hits while eye temperature was not efficient for this purpose.

Considering the lack of consensus related to the impact of selective IL-6 receptor inhibition on bone remodeling and the scarcity of reports, especially on large bone defects, this study proposed to evaluate the biological impact of the selective inhibitor of interleukin-6 receptor (tocilizumab) in an experimental model of critical calvarial defect in rats. In this preclinical and in vivo study, 24 male Wistar rats were randomly divided into two groups (n=12/group): defect treated with collagen sponge (CG) and defect treated with collagen sponge associated with 2 mg/kg tocilizumab (TCZ). The defect in the parietal bone was created using an 8-mm diameter trephine drill. After 90 days, the animals were euthanized, and tissue samples (skull caps) were evaluated through micro-CT, histological, immunohistochemistry, cytokines, and RT-qPCR analyses. Tocilizumab reduced mononuclear inflammatory infiltration (P<0.05) and tumor necrosis factor (TNF)-α levels (P<0.01) and down-regulated tissue gene expression of BMP-2 (P<0.001), RUNX-2 (P<0.05), and interleukin (IL)-6 (P<0.05). Moreover, it promoted a stronger immunostaining of cathepsin and RANKL (P<0.05). Micro-CT and histological analyses revealed no impact on general bone formation (P>0.05). The bone cells (osteoblasts, osteoclasts, and osteocytes) in the defect area were similar in both groups (P>0.05). Tocilizumab reduced inflammatory cytokines, decreased osteogenic protein, and increased proteases in a critical bone defect in rats. Ninety days after the local application of tocilizumab in the cranial defect, we did not find a significant formation of bone tissue compared with a collagen sponge.

To evaluate the effects of glutamine (Gln) supplementation on sow performance during late gestation and lactation and their offspring, eighty pregnant, multiparous sows of a commercial hybrid line were used in a completely randomized, 2 χ 2 experimental design at the end of gestation and lactation, respectively. Females were subjected to a control diet or a Gln-supplemented diet (1% of L-glutamine) from 85 d of gestation until farrowing. During lactation, the dietary treatment groups were CON_C: without Gln supplementation; CON_G: Gln only during lactation; GLN_C: Gln only during gestation; GLN_ GLN: Gln during gestation and lactation. At 105 d of gestation, there was no statistical difference regarding the body weight of the sows, however, sows fed the Gln-supplemented diet had greater backfat thickness at P1 and loin depth at P2 than control sows. Placental weight and efficiency showed no effect between treatments. Litters born from Gln-supplemented sows tended to be heavier at birth compared to control litters, reducing the probability of piglets weighing less than 1.5 kg. In addition, litters from supplemented sows had a lower standard deviation of BW at birth. There were no effects of dietary treatments on the performance of sows and offspring during the lactation period. Maternal Gln supplementation during late gestation improved piglet weight and litter uniformity at birth without affecting sow body composition after farrowing.

Abstract Objective: To analyze the performance of the cystic fibrosis (CF) newborn screening (NBS) program over its first five years in a Brazilian northeastern state. Methods: A population-based study using a screening algorithm based on immunoreactive trypsinogen (IRT)/IRT. Data were retrieved from the state referral screening center registry. The program performance was evaluated using descriptive indicators such as the results of an active search, coverage, newborn’s age at the time of blood sampling, the time between sample collection and its arrival at the laboratory, and the child’s age at diagnosis of disease. Results: The public CF screening program covered 82.6% of the 1,017,576 births that occurred, with an accumulated five-year incidence of 1:20,767 live births. The median (25th-75th) age at diagnosis was 3.5 (2.3–7.3) months. The sampling before 7 days of life for the first IRT (IRT1) increased between 2013 and 2017 from 42.2 to 48.3%. Around 5% of IRT1 samples and 30% of the second samples were collected after 30 days of life. In the first and second stages of screening, 23.6% and 19.9% of the infants, respectively, were lost to follow-up. In both stages of screening, the samples were retained at the health units for a median (25th–75th) of 9.0 (7.0–13.0) days. Conclusions: The coverage by the CF-NBS program was satisfactory as compared to other Brazilian state rates and the percentage of IRT1 samples collected within the first week of life increased progressively. However, time of samples retention at the health units, inappropriate sampling, inherent methodological problems, and loss of follow-up need to improve.

Abstract Background: Elderly patients are more susceptible to Coronavirus Disease-2019 (COVID-19) and are more likely to develop it in severe forms, (e.g., Acute Respiratory Distress Syndrome [ARDS]). Prone positioning is a treatment strategy for severe ARDS; however, its response in the elderly population remains poorly understood. The main objective was to evaluate the predictive response and mortality of elderly patients exposed to prone positioning due to ARDS-COVID-19. Methods: This retrospective multicenter cohort study involved 223 patients aged ≥ 65 years, who received prone position sessions for severe ARDS due to COVID-19, using invasive mechanical ventilation. The PaO2/FiO2 ratio was used to assess the oxygenation response. The 20-point improvement in PaO2/FiO2 after the first prone session was considered for good response. Data were collected from electronic medical records, including demographic data, laboratory/image exams, complications, comorbidities, SAPS III and SOFA scores, use of anticoagulants and vasopressors, ventilator settings, and respiratory system mechanics. Mortality was defined as deaths that occurred until hospital discharge. Results: Most patients were male, with arterial hypertension and diabetes mellitus as the most prevalent comorbidities. The non-responders group had higher SAPS III and SOFA scores, and a higher incidence of complications. There was no difference in mortality rate. A lower SAPS III score was a predictor of oxygenation response, and the male sex was a risk predictor of mortality. Conclusion: The present study suggests the oxygenation response to prone positioning in elderly patients with severe COVID-19-ARDS correlates with the SAPS III score. Furthermore, the male sex is a risk predictor of mortality. Background Disease2019 Disease 2019 Disease-201 COVID19 COVID 19 (COVID-19 forms e.g., eg e g (e.g. ARDS. .

In this work reports the development of a low-cost X-ray machine for teaching purposes, the acquisition and analysis of radiographs of various objects, as well as the construction of a Geiger-Müller counter and a goniometer, for studies on diffraction and absorption. The equipment consists of reused parts of obsolete electronic devices, requiring only the acquisition of a Geiger-Müller ampoule and some components for the X-ray sensor and the oscillator, used to raise the voltage in the transformer. The entire device can be cost around $250.00. Measurements were taken to characterize the equipment, such as counting the number of emitted X-ray photons. With the equipment, it was possible to obtain radiographs and some studies on X-ray absorption. It was observed that for quantitative analyzes of greater reliability involving diffraction and absorption, it is necessary to replace the alternative ampoule used by a low-cost industrial one, but maintaining all developed structure.

In this work we present the construction of a magnetic field meter (gaussmeter) with high sensitivity and detection from 1 to 80 mT, consisting of simple electronic components, with a proposal of application in an experimental setup for the generation of pure spin currents through the effect spin Seebeck. Through a USB cable, the device is powered and exchanges data with a computer via communication in C + + language with Arduino Uno, together with a LabVIEW graphical interface. To perform measurements in deep environments, such as inside electromagnets, a Hall probe was developed. The equipment also has an LCD screen. The magnetic field sensor used is the SS49E, with which it was possible to obtain measurements with appropriate resolution and range. The developed gaussmeter was used in the development of an experimental setup for investigations of the spin Seebeck and spin Hall effects, where it was possible to estimate the spin Hall angle for bilayers formed by a platinum (Pt) film grown on a YIG insulating magnetic film. Therefore, the developed gaussmeter has the potential to be used both in teaching and research environments and its main advantage is the low production cost, approximately US$ 22.00.

ABSTRACT: Dental and periodontal affections consist of health concerns of great importance in sheep flocks, as they affect the health and welfare of animals and represent one of the main causes of premature slaughter. Studies on the occurrence of these conditions in sheep are scarce in Brazil. The present study aimed to evaluate the prevalence of periodontal diseases and tooth wear in sheep flocks in the State of Goiás. For this, a clinical oral examination was conducted on 325 sheep from seven farms in six municipalities of the State. Periodontal lesions, characterized by gingival recession in at least one incisor tooth, were observed in 48.3% (157/325) of the sheep, while in cheek teeth it occurred in 13.2% (43/325) of the evaluated sheep. Dental wear on cheek teeth was identified in 69.2% (255/325) of the sheep, and 10.7% (35/325) of the ovines showed dental wear on incisor teeth. Sheep older than 36 months had an increase in the frequency of tooth wear. A total of 171 (52.62%) out of the 325 examined sheep had signs of bleeding on probing, which is compatible with gingivitis, and 69 (40.36%) were older than 36 months. Thirty-eight (11.69%) out of the 325 evaluated ovines had gingivitis in all teeth, among which 21 (55.26%) were older than 36 months. Logistic regression analysis allowed the observation that age was associated with the occurrence of gingivitis. Less frequent changes such as periodontal pockets and loss of at least one tooth were also observed in 4.9% (16/325) and 17.8% (58/325) of the sheep, respectively. It indicates that the presence of periodontal diseases and tooth wear is a common occurrence in the evaluated flocks. Therefore, there is a need to include the oral health of sheep in the routine of the farm as an essential preventive measure to improve the quality of life, animal welfare, and zootechnical indices.

RESUMO: As afecções dentárias e periodontais constituem uma preocupação sanitária de grande importância em rebanhos ovinos, uma vez que afetam a saúde e o bem-estar dos animais, e representam uma das principais causas para o abate prematuro. No Brasil, estudos sobre a ocorrência dessas afecções em ovinos são escassos. Assim, o presente estudo teve como objetivo avaliar a prevalência de doenças periodontais e desgaste dentário em rebanhos ovinos no estado de Goiás. Para isso, realizou-se o exame clínico bucal em 325 ovinos em sete propriedades rurais de seis municípios do estado. As lesões periodontais, caracterizadas por recessão gengival em, pelo menos, um dente incisivo, foram observadas em 48,3% (157/325) dos ovinos, enquanto nos mastigatórios ocorreu em 13,2% (43/325) dos ovinos avaliados. O desgaste dentário em dentes mastigatórios foi identificado em 69,2% (255/325) dos ovinos e 10,7% (35/325) dos ovinos apresentaram desgaste dentário em dentes incisivos. Ovinos com idade superior a 36 meses tiveram um aumento na frequência do desgaste dentário. Dos 325 ovinos examinados, 171 (52,62%) apresentaram sinais de sangramento à sondagem, compatíveis com o quadro de gengivite, sendo que 69 (40,36%) apresentaram idade superior a 36 meses. Dos 325 ovinos avaliados, 38 (11,69%) apresentaram gengivite em todos os dentes, dos quais 21 (55,26%) apresentaram idade superior a 36 meses. Pela análise de regressão logística, foi possível observar que a idade mostrou associação com a ocorrência de gengivite. Alterações menos frequentes como a bolsa periodontal e a perda de, pelo menos, um elemento dentário também foram observadas em 4,9% (16/325) e 17,8% (58/325) dos ovinos, respectivamente. Os resultados do presente estudo indicam que a presença doenças periodontais e desgaste dentário é uma ocorrência comum nos rebanhos avaliados. Portanto, enfatiza-se a necessidade de incluir a saúde bucal dos ovinos na rotina da propriedade como uma medida preventiva essencial para melhorar a qualidade de vida e o bem-estar dos animais, bem como os índices zootécnicos.

Resumo O bicudo-do-algodoeiro, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), é uma praga-chave da cultura do algodão no Brasil. Fatores climáticos adversos, como altas temperaturas e baixa umidade do solo, desidratam os botões florais de algodão ovipositados caídos ao solo e causam alta mortalidade de seus descendentes dentro dessas estruturas vegetais.O objetivo desta pesquisa foi avaliar a mortalidade do bicudo-do-algodoeiro em lavouras de algodão irrigadas por gotejamento e aspersão. O delineamento experimental foi em blocos casualizados com dois tratamentos: cultivo de algodão irrigado por gotejamento (T1) e aspersão (T2, testemunha) com dezesseis repetições. Cada parcela possuía uma gaiola de emergência, instalada entre duas fileiras de algodão por sistema de irrigação, com 37 botões florais de algodão com orifícios de oviposição, brácteas abertas e amarelecidas, para captura do bicudo adulto. O número médio de bicudos que emergiu dos botões florais de algodão e as causas de mortalidade, em diferentes estágios de desenvolvimento, foram determinados por tratamento. As tabelas de vida de terceira geração do bicudo-do-algodoeiro foram preparadas usando os dados de mortalidade natural em tratamentos de irrigação por gotejamento e aspersão e as taxas de mortalidade reais, aparentes e indispensáveis e a letalidade de cada causa de mortalidade. Concluímos que a aplicação de água diretamente na zona radicular das plantas de forma direcionada, utilizando o sistema de irrigação por gotejamento, pode causar altas mortalidade dos estágios imaturos do bicudo-do-algodoeiro nos botões florais de algodão caídos no solo. Isso ocorre porque os botões florais de algodão caídos no solo mais seco e mais quente entre as fileiras do algodão irrigado por gotejamento desidratam, causando a morte dos bicudos. Isso é importante por poder reduzir a densidade populacional desse inseto e, consequentemente, o número de aplicações de inseticidas químicos para seu controle. Assim, contribuindo para aumentar a viabilidade da produção de algodão, principalmente em áreas do semiárido brasileiro em sistema orgânico.

Abstract The cotton boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), is a key cotton crop pest in Brazil. Adverse climatic factors, such as high temperatures and low soil moisture, dehydrate oviposited cotton squares (bud flowers) on the ground and cause high mortality of its offspring within these plant structures. The objective of this research was to evaluate the mortality of the cotton boll weevil in drip and sprinkler irrigated cotton crops. The experimental design was in randomized blocks with two treatments: drip (T1) and sprinkler (T2, control) irrigated cotton crops with sixteen replications. Each parcel had one emergence cage, installed between two cotton rows per irrigation system, with 37 cotton squares with opened oviposition punctures and yellowish bracts, to capture adult cotton boll weevils. The average number of boll weevils that emerged from the cotton squares and the causes of mortality at different development stages were determined per treatment. Third-generation life tables of the boll weevil were prepared using the natural mortality data in drip and sprinkler irrigation treatments and plus actual, apparent and indispensable mortality rates and the lethality of each mortality cause. We conclude that the application of water directly to the root zone of the plants in a targeted manner, using the drip irrigation system, can cause high mortality of the cotton boll weevil immature stages inside cotton squares fallen on the ground. This is because the cotton squares fallen on the drier and hotter soil between the rows of drip-irrigated cotton dehydrates causing the boll weevils to die. This is important because it can reduce its population density of the pest and, consequently, the number of applications of chemical insecticides for its control. Thus, contributing to increase the viability of cotton production, mainly in areas of the Brazilian semiarid region where the cotton is cultivated in organic system.

RESUMO A brucelose é uma das doenças de caráter zoonótico mais difundidas no mundo, representando um grande problema econômico e de saúde pública. A Brucella melitensis, a B. suis e a B. abortus são consideradas as mais patogênicas espécies para humanos. A espécie apontada como a mais virulenta é a B. melitensis, endêmica em várias partes do mundo, particularmente o biovar 3 na região do Mediterrâneo e na Europa Oriental. Alguns países da América Latina são seriamente afetados pelo biovar 1, especialmente México, Peru e norte da Argentina. O Brasil é considerado livre desse agente etiológico, porém sempre há o questionamento se a infecção não ocorre ou se falta pesquisa. Diante dessa questão, o objetivo deste trabalho foi investigar a ocorrência de anticorpos contra amostras lisas de Brucella em caprinos e ovinos dos estados de Sergipe, Bahia, Ceará e Paraíba. Todas as amostras foram submetidas à triagem pelo teste do antígeno acidificado tamponado (AAT). Como testes confirmatórios, utilizou-se a reação de fixação de complemento (RFC) e também o teste de polarização fluorescente (TPF). Nenhuma amostra foi positiva nos testes confirmatórios (RFC e TPF). Esse resultado comprova que a infecção por B. melitensis é exótica no Brasil.

ABSTRACT Brucellosis is a zoonotic disease widespread almost all over the world, representing a significant economic and public health problem. Brucella melitensis, B. suis and B. abortus are considered the most pathogenic species for humans. The most virulent species, B. melitensis is endemic in many parts of the world, particularly the biovar 3 in the Mediterranean and Eastern Europe. Some Latin American countries are seriously affected by biovar 1, especially Mexico, Peru and northern Argentina. Furthermore, while Brazil is considered free of this etiologic agent, one recurrent question is whether this infection really does not occur in Brazil or there is a lack of research/data on the subject. To answer this question, this study aims to investigate the occurrence of antibodies against smooth Brucella in goats and sheep in the states of Sergipe, Paraíba, Ceará and Paraíba. All samples were screened by the Rose Bengal test (RBT). The complement fixation (CFT) and the fluorescence polarization (FPT) tests were used as confirmatory tests. There were no positive samples in the confirmatory tests (both CFT and FPT). We, therefore, conclude that this result reinforces the previous knowledge regarding the exotic status of B. melitensis infection in Brazil.

Cisplatin is an effective antineoplastic agent, but its use is limited by its nephrotoxicity caused by the oxidative stress in tubular epithelium of nephrons. On the other hand, regular exercise provides beneficial adaptations in different tissues and organs. As with many drugs, dosing is extremely important to get the beneficial effects of exercise. Thus, we aimed to investigate the influence of exercise intensity and frequency on cisplatin-induced (20 mg/kg) renal damage in mice. Forty male Swiss mice were divided into five experimental groups (n=8 per group): 1) sedentary; 2) low-intensity forced swimming, three times per week; 3) high-intensity forced swimming, three times per week; 4) low-intensity forced swimming, five times per week; and 5) high-intensity forced swimming, five times per week. Body composition, renal structure, functional indicators (plasma urea), lipid peroxidation, antioxidant enzyme activity, expression of genes related to antioxidant defense, and inflammatory and apoptotic pathways were evaluated. Comparisons considered exercise intensity and frequency. High lipid peroxidation was observed in the sedentary group compared with trained mice, regardless of exercise intensity and frequency. Groups that trained three times per week showed more benefits, as reduced tubular necrosis, plasma urea, expression of CASP3 and Rela (NFkB subunit-p65) genes, and increased total glutathione peroxidase activity. No significant difference in Nfe2l2 (Nrf2) gene expression was observed between groups. Eight weeks of regular exercise training promoted nephroprotection against cisplatin-mediated oxidative injury. Exercise frequency was critical for nephroprotection.

The goal of the present study was to compare pulmonary function test (PFT) and cardiopulmonary exercise test (CPET) performance in COVID-19 survivors with a control group (CG). This was a cross-sectional study. Patients diagnosed with COVID-19, without severe signs and symptoms, were evaluated one month after the infection. Healthy volunteers matched for sex and age constituted the control group. All volunteers underwent the following assessments: i) clinical evaluation, ii) PTF; and iii) CPET on a cycle ergometer. Metabolic variables were measured by the CareFusion Oxycon Mobile device. In addition, heart rate responses, peak systolic and diastolic blood pressure, and perceived exertion were recorded. Twenty-nine patients with COVID-19 and 18 healthy control subjects were evaluated. Surviving patients of COVID-19 had a mean age of 40 years and had higher body mass index and persistent symptoms compared to the CG (P<0.05), but patients with COVID-19 had more comorbidities, number of medications, and greater impairment of lung function (P<0.05). Regarding CPET, patients surviving COVID-19 had reduced peak workload, oxygen uptake (V̇O2), carbon dioxide output (V̇CO2), circulatory power (CP), and end-tidal pressure for carbon dioxide (PETCO2) (P<0.05). Additionally, survivors had depressed chronotropic and ventilatory responses, low peak oxygen saturation, and greater muscle fatigue (P<0.05) compared to CG. Despite not showing signs and symptoms of severe disease during infection, adult survivors had losses of lung function and cardiorespiratory capacity one month after recovery from COVID-19. In addition, cardiovascular, ventilatory, and lower limb fatigue responses were the main exercise limitations.
