RESUMO

This study aimed to evaluate the effects of Protium heptaphyllum fruit essential oil (PHEO) on the physiology of silver catfish (Rhamdia quelen) during anesthesia and recovery, through studying echocardiograms, oxidative status, and metabolic parameters. Three experiments were performed: (1) 50 silver catfish juveniles were submitted to anesthesia and recovery tests with 300, 400, 500, 600, and 700 mg L-1 of PHEO. (2) Echocardiogram analysis was performed in anesthetized and non-anesthetized fish. (3) Biochemical parameters were evaluated at 0, 30, 60, and 120 min of recovery after being anesthetized for 3 min with 600 mg L-1 PHEO. Times to sedation and deep anesthesia were reduced with PHEO increasing concentrations. The echocardiogram showed a higher cardiac rate in anesthetized fish. Plasma glucose levels increased in control fish through recovery time, but anesthetized fish showed lower levels than controls at 120 min of recovery. Metabolic parameters such as plasma and hepatic glucose did not show changes considering the recovery time of up to 120 min. Hepatic glycogen, lactate, and triglycerides reduced their levels over recovery times. Fish anesthetized enhanced superoxide dismutase activity and thiobarbituric acid reactive substances levels but decreased reduced glutathione (GSH) levels at 30 min compared to controls. After 60 min, GSH values were significantly higher in anesthetized fish than in controls. These results suggest that PHEO at 600 mg L-1 is an effective anesthetic for the rapid handling of silver catfish, providing stable metabolic parameters and enhanced antioxidant responses during recovery. Echocardiogram analysis confirms the anesthetic effect, supporting PHEO as a viable and efficient option for fish anesthesia in aquaculture. The use of PHEO in aquaculture can enhance fish welfare by reducing stress during handling and transportation, potentially leading to improved growth, health, and survival rates.

RESUMO

This study evaluated the use of essential oil of Ocimum gratissimum (EOOG) for anesthesia and in transport of Colossoma macropomum. Experiment 1, Test 1, anesthesia induction and recovery times were determined using different EOOG concentrations (0, 20, 50, 100, 200, 300 mg L-1), with two size classes: Juveniles I (0.86 g) and Juveniles II (11.46 g) (independent tests in a completely randomized design). Based on the results of Test 1, in Test 2 Juveniles II were exposed to EOOG concentrations: 0, 20, 100 mg L-1. Tissue samples were collected immediately after induction and 1 h post-recovery, to assess oxidative status variables. Experiment 2, Juveniles I (0.91 g) and Juveniles II (14.76 g) were submitted to transport in water with different concentrations of EOOG (0, 5, 10 mg L-1) (independent tests in a completely randomized design). The effects on oxidative status variables were evaluated. Concentrations between 50 and 200 mg L-1 EOOG can be indicated for Juveniles I, while concentrations between 50 and 100 mg L-1 EOOG for Juveniles II. The concentration of 100 mg L-1 EOOG was able to prevent oxidative damage in the liver. In Experiment 2, the concentrations of 5 and 10 mg L-1 EOOG added to the transport water caused sedation for both studied size classes of juveniles and did not cause oscillations in water quality variables nor any mortality. The concentration of 10 mg L-1 EOOG improved the oxidative status. It can be concluded that EOOG can be used for anesthesia and transport of C. macropomum.

RESUMO

Objective: To evaluate the progression of caries around orthodontic brackets after the enamel has been exposed to lacteal products containing probiotics. Methods: Orthodontic brackets were bonded to the enamel surfaces. The test specimens were randomly divided into six groups: G1-negative control; G2-positive control, exposed to culture environment only (without microorganisms); G3-exposed to the cariogenic environment and the fermented cow's milk without probiotic; G4-exposed to the cariogenic environment and fermented cow's milk with probiotic; G5-exposed to the cariogenic environment and yogurt without probiotic; and G6-exposed to the cariogenic environment and yogurt with probiotic. The groups were placed in brain heart infusion medium, supplemented with 2% sucrose and with 1x106 cells/ml of Streptococcus mutans and Streptococcus salivarius (ATCC). The Shapiro-Wilk, Levene, Student t, Kruskal-Wallis, and Mann-Whitney tests were used. Results: all groups exposed to the ATCC strains showed lower final microhardness, compared to the negative control (p0.05). Conclusions: Lacteal products are not able to prevent the progression of caries around orthodontic brackets.

RESUMO

One challenge of the citrus industry is the treatment and disposal of its effluents due to their high toxicity, substantial organic load, and consequent resistance to conventional biotechnological processes. This study introduces a novel approach, using electrochemical oxidation with a boron-doped diamond anode to efficiently remove organic compounds from biodegraded pulp wash (treated using the fungus Pleurotus sajor-caju.) The findings reveal that employing a current density of 20 mA cm-2 achieves notable results, including a 44.1% reduction in color, a 70.0% decrease in chemical oxygen demand, an 88.0% reduction in turbidity, and an impressive 99.7% removal of total organic carbon (TOC) after 6 h of electrolysis. The energy consumption was estimated at 2.93 kWh g-1 of removed TOC. This sequential biological-electrochemical procedure not only significantly reduced the mortality rate (85%) of Danio rerio embryos but also reduced the incidence of morphologically altered parameters. Regarding acute toxicity (LC50) of the residue, the process demonstrated a mortality reduction of 6.97% for D. rerio and a 40.88% lethality decrease for Lactuca sativa seeds. The substantial reduction in toxicity and organic load observed in this study highlights the potential applicability of combined biological and electrochemical treatments for real agroindustrial residues or their effluents.

RESUMO

INTRODUCTION: Cupping therapy is a widely used technique in Brazilian physical therapy for the treatment of musculoskeletal disorders. However, there is limited scientific evidence to support its effectiveness. OBJECTIVE: To investigate the profile, training, clinical practice, and scientific updates of Brazilian Physical Therapists who use cupping therapy as a therapeutic resource for musculoskeletal disorders. METHODS: A cross-sectional study was conducted through an online questionnaire, including 646 Physical Therapists who use cupping therapy in their practice. All data were analysed descriptively. RESULTS: Cupping therapy is a technique that has been widely adopted in clinical practice by Physical Therapists, particularly among young, female professionals who have recently graduated from private universities. The primary reason for interest in this technique among these Physical Therapists is the high demand from patients. Additionally, it is often used in conjunction with other manual therapeutic techniques. They identified easy access, low cost, and ease of use as the key factors that make cupping therapy an attractive option. However, a lack of high-quality scientific evidence, as described in the literature, was identified as a major barrier to its use. CONCLUSION: The Physical Therapists included in this study use cupping therapy in their clinical practice, relying heavily on their own experience and the preferences of their patients, rather than utilizing the third pillar of evidence-based practice, which is to rely on the best available evidence. This study suggests that these Physical Therapists are currently implementing a technique without current scientific recommendations for its use in the treatment of musculoskeletal disorders.

RESUMO

Background: Pogostemon heyneanus leaves infusions are relevant in ethnopharmacology for treating colds, coughs, headaches, and asthma. Purpose: The essential oil chemical composition of a Pogostemon heyneanus specimen was monthly monitored from October 2021 to July 2022 to evaluate the climatic influences on its yield and chemical composition and antinociceptive, andanti-inflammatory properties. Methods: The leaves, collected monthly over a 10-month period, were submitted to hydrodistillation. The oils obtained were analyzed by gas chromatography coupled to a mass spectrometer and gas chromatography coupled to flame ionization detector. The P. heyneanus essential oil (PhEO) was tested in vivo to evaluate its peripheral analgesic actions through the abdominal writhing test induced by acetic acid, and peripheral analgesia by tail immersion. Neurogenic and inflammatory pain were evaluated by formalin test, and acute oral toxicity of the oil was also verified. Results: PhEO presented 27 chemical constituents with the highest predominance of patchoulol (43.6%-76.9%), α-bulnesene (0.2%-12.7%), α-guaiene (0.4%-8.9%), seychellene (3.8%-5.1%) and pogostol (0.0%-8.2%). The climatic parameters insolation, humidity, rainfall, and temperature did not influence the essential oil yield or the main chemical constituents, except for pogostol, which presented a strong (r = 0.73) and statistically significant (p < 0.05) correlation with temperature. PhEO did not display toxicity at the maximum 300 mg/kg dosage. The oil showed low peripheral and central analgesic action at 100 mg/kg, while in the neurogenic and inflammatory pain inhibition tests, no actions related to PhEO were observed. In the carrageenan-induced peritonitis test, PhEO did not reduce the migration of leukocytes to the peritoneal cavity compared to the control group. Conclusion: Pogostemon heyneanus is a resistant plant to seasonal influences and a source of patchoulol. Despite ethnopharmacological indications, no in-vivo biological activities such as neurogenic or inflammatory pain were identified in the present work. So, the low influence of the climatic parameters on chemical composition can infer that the low pharmacological activity is also not subject to climatic variations, that is, it does not change due to the climate.

RESUMO

Background & Aims: Lipid droplet (LD) accumulation in cells and tissues is understood to be an evolutionarily conserved tissue tolerance mechanism to prevent lipotoxicity caused by excess lipids; however, the presence of excess LDs has been associated with numerous diseases. Sepsis triggers the reprogramming of lipid metabolism and LD accumulation in cells and tissues, including the liver. The functions and consequences of sepsis-triggered liver LD accumulation are not well known. Methods: Experimental sepsis was induced by CLP (caecal ligation and puncture) in mice. Markers of hepatic steatosis, liver injury, hepatic oxidative stress, and inflammation were analysed using a combination of functional, imaging, lipidomic, protein expression and immune-enzymatic assays. To prevent LD formation, mice were treated orally with A922500, a pharmacological inhibitor of DGAT1. Results: We identified that liver LD overload correlates with liver injury and sepsis severity. Moreover, the progression of steatosis from 24 h to 48 h post-CLP occurs in parallel with increased cytokine expression, inflammatory cell recruitment and oxidative stress. Lipidomic analysis of purified LDs demonstrated that sepsis leads LDs to harbour increased amounts of unsaturated fatty acids, mostly 18:1 and 18:2. An increased content of lipoperoxides within LDs was also observed. Conversely, the impairment of LD formation by inhibition of the DGAT1 enzyme reduces levels of hepatic inflammation and lipid peroxidation markers and ameliorates sepsis-induced liver injury. Conclusions: Our results indicate that sepsis triggers lipid metabolism alterations that culminate in increased liver LD accumulation. Increased LDs are associated with disease severity and liver injury. Moreover, inhibition of LD accumulation decreased the production of inflammatory mediators and lipid peroxidation while improving tissue function, suggesting that LDs contribute to the pathogenesis of liver injury triggered by sepsis. Impact and Implications: Sepsis is a complex life-threatening syndrome caused by dysregulated inflammatory and metabolic host responses to infection. The observation that lipid droplets may contribute to sepsis-associated organ injury by amplifying lipid peroxidation and inflammation provides a rationale for therapeutically targeting lipid droplets and lipid metabolism in sepsis.

RESUMO

Adequate nutrition before and during pregnancy, as well as postpartum, is among the major contributors to maternal and newborn health. Physiotherapists' knowledge of this area is still scarce, although their clinical practice has been linked to newborns' neuropsychomotor development, which, in turn, is influenced by maternal health and nutritional status. Therefore, this study aimed to evaluate the nutritional knowledge of physiotherapists regarding maternal and newborn health. A total of 70 Brazilian physiotherapists (32.2 ± 6.0 years; 72.9% females) were evaluated between November 2019 and February 2020 for their sociodemographic characteristics, professional experience, and nutritional knowledge about maternal and newborn health through a validated questionnaire personally administered by the same trained researcher. Most of the physiotherapists had graduated but had no specialization in maternal and child physiotherapy (96.1% of the females and all the males). The nutritional knowledge about maternal and newborn health was significantly different between the female and male health professionals, as well as between the less and more experienced participants, i.e., female physiotherapists and the more experienced ones had more correct answers on the nutritional questionnaire than the male and less experienced physiotherapists, respectively (p < 0.05). Our results open an interesting window for the future education and training of Brazilian physiotherapists in nutrition.

RESUMO

BACKGROUND: Bone marrow transplantation (BMT) is a standard treatment for several haematologic conditions. Following BMT, patients may develop hepatobiliary complications that impact morbidity and mortality. The differential diagnosis may include drug-induced liver injury (DILI), sepsis-associated liver injury (SALI), sinusoidal obstruction syndrome (SOS), graft-versus-host disease (GVHD), viral hepatitis, ischaemic hepatitis, and fulminant hepatitis. AIMS: To evaluate the frequency, clinical characteristics, and outcomes of patients with hepatobiliary alterations associated with BMT in a tertiary referral centre. METHODS: This was a cross-sectional study with data collected from the medical records of patients undergoing BMT between January 2017 and June 2022. We diagnosed hepatobiliary complications based on established criteria. RESULTS: We included 377 patients; 55.7% had hepatobiliary complications. Female gender, pre-BMT hepatobiliary alteration, and haploidentical allogeneic transplantation were associated with increased risk with odds ratios (OR) of 1.8 (p = 0.005), 1.72 (p = 0.013) and 3.25 (p = 0.003), respectively. Patients with hepatobiliary complications spent longer in the hospital than those without (27.7 × 19.3 days, respectively; p < 0.001). Among 210 patients with hepatobiliary complications, 28 died compared to 5 of 167 without complications (OR 4.98; p = 0.001). CONCLUSIONS: Hepatobiliary complications are frequent in patients undergoing BMT. There is a greater risk of their occurrence in women, people with pre-BMT liver alterations, and in haploidentical transplants. The occurrence of these complications increases the length of stay and is associated with a higher risk of death.

Introduction:Integrative and Complementary Health Practices integrate ancient practices and wisdom with current western biomedical knowledge. Within theUnified Health System, specifically in Primary Health Care, the main place where these practicesare applied is in Basic Health Units.Objective:To evaluate the use of these practicesin the Basic Units from the municipality of Mossoró/Rio Grande do Norte.Methodology:A cross-sectional and descriptive study with a quantitative approach was carried out with Basic Health Unit managers from Mossoró. Two questionnaires were used: one to assess the Basic Unit managers' knowledge aboutintegrative practices; and the other to evaluate their use and implementation process. The data were collected by applying questionnaires online using the Google Forms tool. Results:Twenty-three managers, who totaled a percentage of 48.9% in the study, answered the questionnaires. Most of the participants showed knowledge about the Practices, among which wecan mention the following as the best known: Acupuncture, Meditation and Herbal Medicine. Only 17.4% of the Basic Health Units offerthese practices, with Phytotherapy as the main one. Their application of these is mostly in charge of nurses, with mental health and muscle pain as the most common indications. Failure in the attempt to implement these practices was attributed to lack of professional training and resources, whereas their interruption was due to shortage of materials and to the COVID-19 pandemic.Conclusions:This study found a low prevalence of these practicesin the city of Mossoró. The need for qualification and training of thePrimary Health Care professionals inIntegrative and Complementary Practicesis highlighted, as well as better management of resources for effective implementation in the municipality, given their importance in terms of comprehensive health care and disease prevention (AU).

RESUMO

This study aimed to identify the regions of the body surface of silver catfish (Rhamdia quelen) with a higher population of mucous cells in the skin. Additionally, the effects of stressful conditions, such as different stocking densities and food deprivation, on the proliferative response of mucous cells in the skin and gill epithelium and their impact on cutaneous mucous lysozyme activity were investigated. Silver catfish were divided into four experimental groups: high stocking density (32 kg/m3) and fed (HSD-F), high stocking density and fasted (HSD-FS), low stocking density (2.5 kg/m3) and fed (LSD-F), and low stocking density and fasted (LSD-FS). Fish in the fed groups received commercial feed twice a day, amounting to 1% of the tank biomass. After a 14-day experimental period, the fish were anesthetized and euthanized. Samples of cutaneous mucous and skin fragments from seven different points and the second left branchial arch were collected. Histological slides of the skin and gills were stained with PAS + Alcian Blue at pH 2.5, and the epidermal mucous lysozyme activity was assessed using the turbidimetric method. The ventral point in front of the ventral fin was found to be the optimal location for collecting cutaneous epithelia due to its higher density of mucous cells. The population of mucous cells in both the skin and gills varied based on the collection point and treatment applied. The highest lysozyme activity in the epidermal mucous was observed in fish from the HSD-F group. Overall, these findings suggest that stocking density and food deprivation create stressful conditions for silver catfish, which modulate their mucosal response to each situation.

RESUMO

BACKGROUND: Although COVID-19 booster vaccination is widely recommended, there is limited long-term, population-level, real-world evidence on the magnitude of improved protection against severe COVID-19 conferred by boosting with monovalent COVID-19 vaccines developed against ancestral SARS-CoV-2, especially in low- or middle-income countries. We present interim results from the first large-scale assessment of the relative vaccine effectiveness (rVE) of first and second booster doses against severe COVID-19 in a low-/middle-income country. METHODS: REFORCO-Brazil is an ongoing, test-negative case-control study (NCT05697705) utilizing Brazil national severe acute respiratory syndrome (SARS) surveillance and vaccination data. In SARS hospitalizations from August 1, 2021 to July 31, 2022, we matched test-positive (via SARS-CoV-2 antigen/reverse transcription polymerase chain reaction [RT-PCR]) cases and test-negative case-controls (via RT-PCR) based on admission date, preceding vaccinations, and age. We evaluated the rVEs of four monovalent COVID-19 vaccines (AZD1222, Ad26.COV2.S, CoronaVac, and BNT162b2) as second boosters compared with any first boosters received ≥4 months previously, and as first boosters compared with primary-series vaccinations completed ≥4 months previously. RESULTS: The overall rVE of second boosters, from 5668 (2238 test-positive) evaluated hospitalizations, was 24.7 % (95 % confidence interval [CI]: 12.6-35.1); the overall rVE of first boosters, from 30,272 (12,063 test-positive) hospitalizations, was 46.8 % (95 % CI: 43.3-50.0). The rVEs of AZD1222 and BNT162b2 were similar: 29.4 % (95 % CI: 8.6-45.5) and 25.5 % (95 % CI: 4.2-42.2), respectively, for second boosters; and 42.5 % (95 % CI: 28.0-54.0) and 50.8 % (95 % CI: 47.5-54.0), respectively, for first boosters. In general, rVEs were higher in elderly (≥80 years) and immunocompromised/high-risk individuals. CONCLUSIONS: Our results support the use of AZD1222 and other adenoviral/mRNA vaccine boosters to maintain protection against COVID-19 hospitalization from Omicron subvariants, including in elderly and immunocompromised individuals at increased risk of accelerated waning or severe outcomes.

RESUMO

ABSTRACT We report the case of a 39-year-old male patient who presented with visual loss in the right eye for 6 weeks. The best-corrected visual acuity was counting fingers in the right eye and 20/30 in the left eye. The fundus examination demonstrated a right retinal detachment inferiorly extending to the fovea and a left macular serous detachment. After multimodal imaging study, the patient was diagnosed as having a bullous variant of central serous chorioretinopathy and treated with oral spironolactone associated with adjuvant laser photocoagulation. The retinal changes resolved after 6 months. The final visual acuity was 20/20 in both eyes.

RESUMO

Asthma is an important health concern in Latin America (LA) where it is associated with variable prevalence and disease burden between countries. High prevalence and morbidity have been observed in some regions, particularly marginalized urban populations. Research over the past 10 years from LA has shown that childhood disease is primarily non-atopic. The attenuation of atopy may be explained by enhanced immune regulation induced by intense exposures to environmental factors such as childhood infections and poor environmental conditions of the urban poor. Non-atopic symptoms are associated with environmental and lifestyle factors including poor living conditions, respiratory infections, psychosocial stress, obesity, and a diet of highly processed foods. Ancestry (particularly African) and genetic factors increase asthma risk, and some of these factors may be specific to LA settings. Asthma in LA tends to be poorly controlled and depends on access to health care and medications. There is a need to improve management and access to medication through primary health care. Future research should consider the heterogeneity of asthma to identify relevant endotypes and underlying causes. The outcome of such research will need to focus on implementable strategies relevant to populations living in resource-poor settings where the disease burden is greatest.

RESUMO

This study aimed to verify the effect of different feeding and stocking conditions during 14 days on the gene expression of several hormones and enzymes related to the stress cascade and metabolic parameters in silver catfish Rhamdia quelen under the following experimental conditions: 1) fed at low stocking density (2.5 kg m-3, LSD-F); 2) fed at high stocking density (32 kg m-3, HSD-F); 3) food-deprived at LSD (LSD-FD); and 4) food-deprived at HSD (HSD-FD). Fish from LSD-F and HSD-F groups were fed daily (1 % of their body mass), while fish from food-deprived groups (LSD-FD and HSD-FD) were not fed during the experimental time. Plasma metabolic parameters (glucose, lactate, triglycerides, and proteins) and hepatosomatic index (HSI) were evaluated. In addition, mRNA expression of genes related to the stress axis (crh, pomca, pomcb, nr3c2, star, hsd11b2 and hsd20b), heat shock protein family (hsp90 and hspa12a), sodium-dependent noradrenaline transporter (slc6a2), and growth axis (gh and igf1) were also assessed. Specific growth rate and HSI decreased in food-deprived fish regardless of stocking density. The HSD-FD group showed weight loss compared to the HSD-F, LSD-F, and LSD-FD groups. Plasma glucose and triglycerides were reduced in food-deprived groups, while lactate and protein levels did not change. The expression of key players of the stress response (crh, pomca, pomcb, hsd11b2, nr3c2, and hsp90b) and growth (gh and igf1) pathways were differently regulated depending on the experimental condition, whereas no statistical difference between treatments was found for hsd20b, scl6a2, hspa12a, and star mRNAs expression. This study suggests that LSD acts as a stressor affecting negatively the physiological status of fed fish, as demonstrated by the reduction in growth rates, altered metabolic orchestration, and a higher crh mRNA expression. In addition, food deprivation also increased mRNA expression of other assessed genes (nr3c2, hsp90b, pomca, and pomcb) in fish from the HSD group, indicating higher responsiveness to stress in this stocking density when combined with food deprivation.

RESUMO

We report the case of a 39-year-old male patient who presented with visual loss in the right eye for 6 weeks. The best-corrected visual acuity was counting fingers in the right eye and 20/30 in the left eye. The fundus examination demonstrated a right retinal detachment inferiorly extending to the fovea and a left macular serous detachment. After multimodal imaging study, the patient was diagnosed as having a bullous variant of central serous chorioretinopathy and treated with oral spironolactone associated with adjuvant laser photocoagulation. The retinal changes resolved after 6 months. The final visual acuity was 20/20 in both eyes.

RESUMO

Este artigo analisa a execução do PMAQ-AB a partir de sua contextualização em um cenário político nacional de profundas transformações, desde o reformismo fraco que promoveu lenta extensão de direitos até o contrarreformismo forte da restauração neoliberal. Para debater os elementos relacionados ao trabalho e às disputas pela distribuição dos recursos públicos, foi realizado estudo de caso com trabalhadores, gestores e conselheiros de saúde em duas capitais do nordeste brasileiro. Os resultados evidenciam o acirramento do conflito distributivo e o resultado desfavorável aos trabalhadores no contexto pós-golpe parlamentar de 2016. As dinâmicas locais expõem processos de contração salarial e individualização das relações de trabalho e a reafirmação da meritocracia como justificativa ideológica da precarização. A isso, trabalhadores se contrapõem pela reafirmação de sua condição coletiva de classe, em favor de benefícios derivados do PMAQ, como recomposição salarial para todos.(AU)


Este artículo analiza la realización del PMAQ-AB a partir de su contextualización en un escenario político nacional de profundas transformaciones, desde el reformismo débil que promovió una lenta extensión de derechos contra el reformismo fuerte de la restauración neoliberal. Para discutir los elementos relacionados al trabajo y a las disputas por la distribución en los recursos públicos se realizó un estudio de caso con trabajadores, gestores y consejeros de salud en dos capitales del nordeste brasileño. Los resultados ponen en evidencia el recrudecimiento del conflicto distributivo y el resultado desfavorable para los trabajadores en el contexto post-golpe parlamentario de 2016. Las dinámicas locales exponen procesos de contracción salarial e individualización de las relaciones de trabajo y la reafirmación de la meritocracia como justificativa ideológica de la precarización. A eso se contraponen los trabajadores por medio de la reafirmación de su condición colectiva de clase, en favor del beneficio derivado del PMAQ con la recomposición salarial para todos.(AU)


This article analyzes the implementation of the Program for Improving Access and Quality of Primary Care (PMAQ-AB) in the context of a national political scenario of deep transformations, from the weak reformism that promoted slow extension of rights to the strong counter-reformism of neoliberal restoration. It is a case study with health workers, managers, and counselors in two capital cities in northeastern Brazil, discussing matters of work and distributive disputes of public resources. Results show the intensification of these conflicts in health and the unfavorable outcome for workers after the parliamentary coup in 2016 political context. Local dynamics expose the wage contraction and individualization of labor relations and the reassertion of meritocracy as an ideological ground for precariousness. Workers oppose this, reaffirming their collective class condition, favoring the benefit derived from PMAQ for fully regaining their group wages.(AU)

RESUMO

Introdução: Desde o início da Pandemia Covid-19 vários países adotaram o isolamento social (lockdown) como medida de contenção para diminuir a propagação do vírus e reduzir o risco de sobrecarga no sistema de saúde. A prática regular do exercício físico ao longo da pandemia poderia atenuar os prejuízos do isolamento e manter a saúde mental e bem-estar dos atletas. Objetivo: Avaliara associação entre os níveis de exercício físico e os níveis de saúde mental em atletas de basquete em cadeira de rodas durante o isolamento social. Métodos: Utilizamos um questionário online dividido em duas seções: avaliação da saúde mental e do nível de exercício físico. Resultados e Discussão: Pontuações mais baixas no questionário Short Form 36(SF-36)foram observadas nos domínios "vitalidade" com uma pontuação de 16, "limitação por aspectos emocionais" com pontuação de 55, "limitação por aspectos físicos" com pontuação de 62,5 seguido por "estado geral de saúde" com pontuação de 63.O questionário Physical Activity Scale for Individuals With Physical Disabilities (PASIPD) mostrou uma percepção baixa em relação ao nível de atividade física nas pessoas com deficiência. Conclusão: Os domínios de saúde geral com menor pontuações no lockdown foi "vitalidade" (16) e "aspectos emocionais" (55) e não foi observado associação forte entre os diferentes domínios da escala SF-36 e o nível de atividade física através da Escala PASIPD (p>0,005).


Introduction: Since the beginning of the Covid-19 pandemic, several countries have adopted social isolation (lockdown) as a containment measure to reduce the spread of the virus and the risk of overloading the health system. Regular physical exercise during the pandemic could mitigate the damage of isolation and maintain the mental health and well-being of wheelchair basketball athletes. Objective: To evaluate the association between physical exercise levels and mental health levels in wheelchair basketball athletes during social isolation. Methods: We used an online questionnaire divided into two sections: mental health assessment and physical exercise level assessment. Results and discussion: Lower scores on the Short Form 36 (SF-36) questionnaire were observed in the domains "vitality" with a score of 16, "limitation by emotional aspects" with a score of 55, "limitation by physical aspects" with a score of 62.5 followed by "general health status" with a score of 63. The Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) showed a low perception of physical activity level in people with disabilities. Conclusion: The general health domains with lower scores in lockdown were "vitality" (16) and "emotional aspects" (55) and no strong association was observed between the different domains of the SF-36 scale and the level of physical activity through the PASIPD Scale (p>0.005).

RESUMO

This study is aimed at estimating genetic parameters, effective population size, inbreeding, and inbreeding depression for birth weight, weaning weight, and average pre-weaning daily weight gain (ADG) in Piau pigs. We used information from 3841 Piau pigs, and four linear models were fitted in single-trait analyses, including or excluding maternal genetic effect, common litter effect, or a combination. The adjustments of the models were compared using the likelihood ratio test, in which the model that presented the best fit for each trait was used to estimate the (co)variance components. The inbreeding depression effect was evaluated using a linear model that included the fixed effects of sex, parity order, contemporary group, and inbreeding coefficient as a fixed covariate. The weights at birth and weaning showed low direct heritabilities (0.08 and 0.05, respectively), while the ADG showed moderate heritability (0.20). The weight at birth showed high genetic correlations with the weight at weaning (0.90) and the ADG (0.82). The weight at weaning and the ADG also showed a high genetic correlation (0.99). There was an inbreeding increase over the generations and a reduction in the effective population size. In the last generation evaluated, all the animals were inbred, the average inbreeding coefficient was 0.07, and the effective population size was 20.8. A significant inbreeding effect on ADG was observed, where an increase of 1% in the inbreeding coefficient resulted in a decrease of 0.005 g in the ADG. Thus, increasing effective population size is mandatory for controlling inbreeding and reducing the loss of variability in this Piau pig population.
