RESUMO

Animal personality has established connections with animal performance, resilience, and welfare which are related to stable behavioral patterns. Precision livestock technologies introduce the opportunity to measure these behavior patterns automatically and noninvasively. Thus, the primary aim of this study was to determine if personality traits in dairy calves measured via standardized personality assessments were associated with activity measured via a commercially available accelerometer. Secondary aims of this study were to investigate if personality traits were associated with feeding behaviors measured via an automatic feeding system (AFS) and with average daily gain (ADG). We characterized personality traits of Holstein calves (n = 49) utilizing standardized personality (novel environment, novel person, novel object, and startle) tests. Behaviors from these tests were summarized and 3 factors were extracted from a principal component analysis to represent calf personality traits: fearful, active, and explorative. Factor scores were regressed against behaviors from the accelerometer and AFS and with ADG. We found that calves that were more active were associated with taking more steps in the home environment, consuming more calf starter, and with reaching the benchmark of 1 kg of starter consumed in a day at a younger age. The trait active was also associated with greater ADG throughout the study. In addition, calves that were more explorative in the personality tests were associated with less starter consumed and lower ADG specifically during the weaning period. The findings of this research contribute to the existing literature by further establishing the links between personality traits and the daily behavioral patterns and performance of young calves. This study suggests the potential for using precision technology to assess and characterize personality traits, thereby enhancing their practical applicability on farms. Future research should focus on evaluating how personality traits, as measured through standardized assessments and precision technologies, correlate with deviations in behavior observed in dairy calves during stressors.

RESUMO

Dairy calves routinely experience disease, pain, and nutritional stressors such as diarrhea, dehorning, and weaning early in life. These stressors lead to changes in behavioral expression that varies in magnitude between individuals, where a greater magnitude change would suggest lower resilience in individuals to a stressor. Thus, this study first aimed to quantify the individual variation in magnitude change in feeding behaviors and activity in response to a bout of diarrhea, dehorning, and weaning. The next objective was to then investigate if personality traits were related to this magnitude of behavioral response in dairy calves, and thus their resilience toward these stressors. Calves were followed with 2 precision livestock technologies (e.g.: an automatic feeding system (AFS), and leg accelerometer) to track behavioral changes in response during the time when the stressors were present. The AFS provided daily measures of milk intake, drinking speed, rewarded and unrewarded visits to the milk feeding station, and calf starter intake. The leg accelerometer provided daily measures of steps, activity index, lying time, and lying bouts. At 23 ± 3 d of age, Holstein dairy calves (n = 49) were subjected to a series of standardized personality tests that exposed calf to novelty and fear stimuli. Factors extracted from a principal component analysis on the behaviors from the personality test were utilized to represent personality traits: Factor 1 ('Fearful'), Factor 2 ('Active') and Factor 3 ('Explorative'). The magnitude change in behaviors from the precision livestock technologies were calculated relative to the behavior performed on the day the stressor occurred (i.e., day of diagnosis; day of dehorning; day weaned). Linear regression models were utilized to determine if calf scores on each factor were associated with magnitude change in behavior for each of the stressor periods with day relative to the stressor included as a repeated measure. Models were run independently for the period leading up to and following each stressor. We found that calves varied in their behavioral responses to diarrhea, dehorning, and weaning stressors, despite being reared in the same environment and experiencing consistent management procedures. Additionally, personality traits measured from standardized tests were associated to both the direction and magnitude of change in behaviors around each stressor. For instance, with diarrhea, calves that were highly 'Fearful' had a greater magnitude change in milk intake and drinking speed following diagnosis than the least 'Fearful' calves. With dehorning, calves that were highly 'Explorative' had a greater magnitude change in lying time when dehorned, but a smaller magnitude change in lying bouts and drinking speed following dehorning, than the least 'explorative' calves. With weaning, calves that were highly 'Active' had a smaller magnitude change in unrewarded visits leading up to and following weaning than calves that were the least 'Active'. Each of the personality traits had a significant association with change in behavior surrounding each of the stressors evaluated, although these associations depended on the type of stressor. These results have implications for how individual calves experience each stressor and therefore individual animal welfare.

RESUMO

Human immunodeficiency virus (HIV) transmission remains an important health issue, with a high burden that is felt across the world. This work aims to analyze the demographic, clinical, and laboratory characteristics of newly diagnosed patients with HIV in a Department of Dermatology and Venereology. A retrospective observational study was conducted from all health records of newly diagnosed patients with HIV from a Dermatology unit from January 2011 to December 2020. A total of 134 patients with new HIV diagnoses were included in the analysis. Concurrent dermatological or venereal diseases were diagnosed in 91.0% of the patients (n=122), being the most common conditions syphilis (22.4%, n=30) and urethritis (14.9%, n=20). Out of all the patients with diagnoses of concurrent sexually transmitted infection (STI) (41.0%, n=55), syphilis was reported in 81.8% of the patients (n=45), gonorrhea in 9.1% (n=5), and chlamydia in 5.5% (n=3). We present a large patient database on the clinical conditions associated with newly diagnosed HIV, concluding that infectious diseases were the most common conditions associated with newly diagnosed HIV.

RESUMO

Lumbar pain is a very common symptom that derives from benign musculoskeletal conditions, rheumatic inflammatory diseases, neoplasms, and referred and/or nociplastic pain. A 70-year-old man with psoriatic arthritis presented with early-onset lumbosacral pain without evident red flags. Symptomatic treatment was unhelpful. Radiographic imaging showed subtle signs of a disease that could easily be missed. Magnetic resonance imaging revealed a massive prostatic malignancy with bone (sacral and iliopubic) metastasis. Awareness must be given not to disregard every lumbar pain as part of the preexisting rheumatic inflammatory disease (spondyloarthropathy in this case) or a common muscle/ligament/articular disarrangement. Persistence of pain, albeit not inflam-matory nor sharp in nature, despite adequate treatment might be just as important as an acute red flag and requires proper follow-up.

RESUMO

Veterinary palliative care consists of end-of-life care of companion animals suffering from terminal or life-limiting diseases. Despite the growing need for veterinary palliative care, little research has been conducted on this topic. This perspective intends to provide an overview of the existing concerns and identify knowledge gaps to motivate further research. As a result, three main areas of research have been identified, namely: i) how to provide palliative care considering welfare implications of different diseases (e.g., pain management); ii) what can be considered a "good death", depending on the individual situation of the animal and its caregiver; iii) how to support caregivers' needs during their companion animal's end-of-life. Therefore, veterinary palliative care involves medical, ethical, and sociological considerations that should be addressed through guidelines and training.

RESUMO

OBJECTIVE: To determine the efficacy of two physiotherapeutic interventions - aquatic therapy (AT) and land-based therapy (LBT) - for reducing pain in women with fibromyalgia. DESIGN: Single-blind, randomised controlled, equivalence trial. SETTING: Fibromyalgia, Chronic Fatigue Syndrome and Multiple Chemical Sensitivity Association in A Coruña, Spain. PARTICIPANTS: Forty women with fibromyalgia were assigned at random in a 1:1 manner to two groups: AT (n = 20) and LBT (n = 20). INTERVENTIONS: Two therapeutic exercise programmes, with 60-min sessions, were undertaken three times per week for 12 weeks. Sessions were carried out in groups by a trained physiotherapist. OUTCOME: The primary outcome was pain intensity (visual analogue scale). The secondary outcomes were pressure pain threshold (algometer), quality of life (Revised Fibromyalgia Impact Questionnaire), sleep quality (Pittsburgh Sleep Quality Index), fatigue (Multidimensional Fatigue Inventory) and physical ability (6-Minute Walk Test). Patients were evaluated at baseline, 12 weeks (post-treatment) and 18 weeks (follow-up). The statistical analysis was per-protocol. P < 0.05 was considered to indicate significance. Effect size was calculated. RESULTS: The mean age was 50 [standard deviation (SD) 9] years, with median body mass index of 27 [interquartile range (IQR) 25-30] kg/m2 and median symptom duration of 11 (IQR 6-15) years. No differences were observed between the groups post-treatment, but differences in favour of AT were found in pain intensity [2.7 (IQR 1.5-4.9) vs 5.5 (IQR 3.3-7.6); p= 0.023; large effect, Cohen's d= 0.8; 95% confidence interval (CI) 0.1-1.5] and sleep quality [12.0 (IQR 7.3-15.3) vs 15.0 (IQR 13.0-17.0); p= 0.030; large effect, Cohen's d= 0.8; 95% CI 0.1-1.5] at follow-up. CONCLUSIONS: The results suggest that AT is better than LBT for reducing pain intensity and improving sleep quality after 6 weeks of follow-up. AT may be a good treatment option for women with fibromyalgia. CLINICAL TRIALS REGISTRATION NUMBER: ClinicalTrials.gov NCT02695875 CONTRIBUTION OF THE PAPER.

RESUMO

The shift towards a circular economy, where waste generation is minimized through waste re-use and the development of valorization strategies, is crucial for the establishment of a low carbon, sustainable, and resource-efficient economy. However, there is a lack of strategies for re-using and valorizing specific types of waste, particularly those containing naturally occurring radioactive materials (NORM), despite the prevalence of industrial activities that produce such waste due to their chemical and radiological hazards. Living organisms, including fungi, are valuable sources of bioactive compounds with various industrial applications. In this study, we assessed the growth and metabolic profile changes of three white rot fungi species in response to low concentrations of a uranium mine effluent containing NORM and metals to explore their potential for producing biotechnologically relevant bioactive compounds. The growth rate was assessed in three different culture media, with and without the uranium mine effluent (1% V/V)), and the metabolic profile was analyzed using FTIR-ATR spectroscopy. Results suggested an improvement in growth rates in media containing the uranium mine effluent, although not statistically significant. T. versicolor showed promise in terms of bioactive compound production. The production of droplets during growth experiments and significant metabolic changes, associated with the production of bioactive compounds like laccase, melanin, and oxalic acid, were observed in T. versicolor grown in mYEPDA with the uranium mine effluent. These findings present new research opportunities for utilizing waste to enhance the biotechnological production of industrially relevant bioactive compounds and promote the development of circular economy strategies for re-using and valorizing NORM-containing waste.

RESUMO

BACKGROUND: The mortality associated with high-risk pulmonary embolism (PE) is remarkably high, and reperfusion to unload right ventricle should be a priority. However, several registries report reperfusion underuse. In Portugal, epidemiological data about the incidence, rate of reperfusion and mortality of high-risk PE are not known. METHODS: Nationwide population-based temporal trend study in the incidence and outcome of high-risk PE, who were admitted to hospitals of the National Health Service in Portugal between 2010 and 2018. High-risk PE was defined as patients with PE who developed cardiogenic shock or cardiac arrest. International Classification of Diseases (ICD), 9th and 10th revision, Clinical Modification codes, were used for data from the period between 2010 and 2016 (ICD-9-CM) and 2017-2018 (ICD-10-CM), respectively. The assessment focused on trends in the use of reperfusion treatment, which was defined by application of thrombolysis or pulmonary embolectomy. A comparison was made between the use or non-use of reperfusion therapy in order to examine trends in in-hospital mortality among high-risk PE cases. RESULTS: From 2010 and 2018, there were 40.311 hospitalization episodes for PE in adult patients at hospitals of the National Health Service in mainland Portugal. There was a significant increase in the annual incidence of PE (41/100.000 inhabitants in 2010 to 46/100.000 in 2018; R2=0.582, p = 0.010). The average annual incidence was 45/100.000 inhabitants/year, with 2,7% of the PE episodes (1104) categorized as high-risk. The mortality rate associated with high-risk PE was high, although it has decreased over the years (74.2% in 2010 to 63.6% in 2018; R2=0.484; p = 0.022). Thrombolytic therapy was underused in high-risk PE, and its usage has not increased in recent years (17.3% in 2010 to 21.1% in 2018, R2=-0.127; p = 0.763). Surgical pulmonary embolectomy was used in 0.27% of cases, and there was no registry of catheter-directed thrombolysis. Patients with high-risk PE undergoing reperfusion therapy had lower in-hospital mortality compared to non-reperfused patients (OR=0.52; IC95% 0.38-0.70). CONCLUSION: In Portugal, between 2010 and 2018, very few patients with PE developed high-risk forms of the disease, but the mortality rate among those patients was high. The low reperfusion rate could be associated with high in-hospital mortality and highlights the need to implement advanced therapies, as an alternative to systemic thrombolysis.

RESUMO

INTRODUCTION AND AIMS: Workplace exposures are widely known to cause specific occupational diseases such as silicosis and asbestosis, but they also can contribute substantially to causation of common respiratory diseases. In 2019, the American Thoracic Society (ATS) and the European Respiratory Society (ERS) published a joint statement on the occupational burden of respiratory diseases. Our aim on this narrative review is to summarise the most recent evidence published after the ATS/ERS statement as well as to provide information on traditional occupational lung diseases that can be useful for clinicians and researchers. RESULTS: Newer publications confirm the findings of the ATS/ERS statement on the role of workplace exposure in contributing to the aetiology of the respiratory diseases considered in this review (asthma, COPD, chronic bronchitis, idiopathic pulmonary fibrosis, hypersensitivity pneumonitis, infectious pneumonia). Except for COPD, chronic bronchitis and infectious pneumonia, the number of publications in the last 5 years for the other diseases is limited. For traditional occupational lung diseases such as silicosis and asbestosis, there are old as well as novel sources of exposure and their burden continues to be relevant, especially in developing countries. CONCLUSIONS: Occupational exposure remains an important risk factor for airways and interstitial lung diseases, causing occupational lung diseases and contributing substantially in the aetiology of common respiratory diseases. This information is critical for public health professionals formulating effective preventive strategies but also for clinicians in patient care. Effective action requires shared knowledge among clinicians, researchers, public health professionals, and policy makers.

RESUMO

PURPOSE: This study was performed with the purpose of analysing the relationship between epileptological and surgical variables and post-operative memory performance, following surgery for refractory mesial temporal lobe epilepsy (MTLE) due to hippocampal sclerosis (HS). METHODS: Logical memory (LM) and visual memory (VM) scores for immediate and late follow-up of 201 patients operated for MTLE/HS were reviewed. Scores were standardized with a control group of 54 healthy individuals matched for age and education. The Reliable Change Index (RCI) was calculated to verify individual memory changes for late LM and VM scores. A multiple linear regression analysis was carried out with the RCI, using LM and VM scores as well as the clinical variables. RESULTS: A total of 112 (56%) patients had right HS. The RCI of the right HS group demonstrated that 6 (7%) patients showed improvement while 5 (6%) patients showed decreased scores in late LM; for late VM, 7 (8%) patients presented improvement, and 2 (3%) patients showed poorer scores. RCI of the left HS group showed that 3 (3%) individuals showed improved scores, while scores of 5 (4%) patients worsened for late LM; for late VM, 3 (3%) patients presented higher scores and 6 (5%) showed lower scores. Left HS and advanced age at onset of the first epileptic seizure were predictors of late LM loss (p<.05). CONCLUSION: Left MTLE/HS and seizure onset at advanced ages were predictive factors for the worsening of late LM. We observed poorer baseline LM function in the left HS group and improvement of LM in some patients who had resection of the right MTL. Patients in the right HS group showed a higher percentage of reliable post-operative improvement for both VM and LM scores.

RESUMO

OBJECTIVE: The objective of our study was to compare the degree of difficulty and complications related to tracheal intubation in an Intensive Care Unit (ICU) before and after the introduction of an intubation protocol based on the Difficult Airway Society guidelines for the management of tracheal intubation in critically ill adults, published in 2018. METHODS: Prospective, observational study comparing all intubations performed in our ICU over 2 periods: pre-protocol (January 2015-January 2019) and post-protocol (February 2019-July 2022). The material used for intubation, the degree of difficulty, and intubation-related complications were recorded. RESULTS: During the study period, 661 patients were intubated - 437 in the pre-protocol period (96% by direct laryngoscopy) and 224 in the post-protocol period (53% with direct laryngoscopy, 46% with video laryngoscopy). We observed an improvement in laryngeal view in the post-protocol period compared to the pre-protocol period (Cormack-Lehane ≥ 2b in 7.6% vs. 29.8%, p < 0.001), and a decrease in the number of moderate-to-severely difficult intubations (6.7% vs. 17.4%, p < 0.001). The first-pass success rate was 92.8% in the post-protocol period compared to 90.2% pre-protocol (p = 0.508). We did not find significant differences in complications between the periods studied. CONCLUSIONS: Intubations performed in the post-protocol period were associated with improved laryngeal view and fewer cases of difficult intubation compared with the pre-protocol period.

RESUMO

The red seaweed Asparagopsis taxiformis has a potent antimethanogenic effect, which has been proven both in vitro and in vivo. Vegetable oil immersions of this seaweed (hereafter Bromoil) help stabilise the bromoform (CHBr3) responsible for its antimethanogenic effect. We evaluate the effects of increasing the levels of CHBr3 in lamb diets on growth performance, methane (CH4) production, animal health and meat quality. Twenty-four Merino Branco ram lambs were fed a ground complete compound feed, supplemented with 50 mL/kg DM of sunflower oil with different CHBr3 content. The treatments were defined by the CHBr3 doses in the oil: 0 mg (control - B0), 15 mg (B15), 30 mg (B30) and 45 mg (B45) of CHBr3 per kg of feed DM. The feed was prepared daily by mixing Bromoil with the compound feed. At the end of the experiment, the lambs were sacrificed, the ruminal content was collected for in vitro fermentation to evaluate CH4 production and organic matter (OM) degradability, and the rumen mucosa was sampled for histological examination. Meat samples were collected for chemical composition and CHBr3 analysis. The half-life of CHBr3 in the air-exposed feed was 3.98 h making it very difficult to establish the practiced level of CHBr3 supplementation. Lambs-fed treatments B30 and B45 decreased DM intake by up to 28%. Average daily gain was also reduced due to CHBr3 supplementation, with B45 showing results 40% lower than B0. DM feed conversion ratio was similar for all treatments. The degradability of OM, the volume of total gas and of gas without CH4 were unaffected by the experimental treatments, evaluated by the in vitro method. However, the volume of CH4 decreased by up to 75% for treatments above 30 mg/kg DM, while the yield of CH4/g OM degraded was reduced by up to 78% with treatments above 30 mg/kg DM. Meat chemical composition was not affected by Bromoil supplementation and no traces of CHBr3 were found in meat samples. During this experiment, the animals presented normal health and behaviour. However, postslaughter examination of the rumen showed distinct lesions on the ventral region of the rumen mucosa of animals supplemented with Bromoil. These lesions were more severe in the animals receiving treatments B30 and B45. This research determined that although concentrations of CHBr3 in the diet above 30 mg/kg DM helped to reduce CH4 emissions, it negatively affected the performance and rumen wall.

RESUMO

Low density sugarcane plantation (LDSP) has been implemented by some sugarcane producers in Brazil, aiming to save seeds and operational costs. The study was carried out in the municipality of Areia, Paraíba, Brazil. Five planting densities were used, varying from 5 to 25 m-2 of buds arranged in randomized blocks, with four replications. Data were measured annually over three cultivation cycles (2017 to 2020), during which the field was fertilized with NPK and the harvests were carried out manually without prior burning. The lower planting density presents higher productivity only in the cane plant (101.03 t ha-1) due to the higher plant height (2.37 m) and the higher number of stalks (11 stalks m-2), suggesting that these variables are due to the greater availability of light, water and photosynthate. However, there is a drastic reduction in sugarcane yield for this lower population in the 2nd ratoon by up to 65.62%, which is correlated with number of stalks per meter. We demonstrate the agronomic viability of LDSP in the population of 10 buds m-2 in relation to conventional planting of sugarcane until the 2nd ratoon. Data are important for future studies to present additional considerations for other production factors, such as the effects of mechanized harvesting and the management of nutrients and water, assessing the sustainability of this large-scale planting system.

RESUMO

Abstract Quilombola communities are present in many Brazilian states living in precarious health conditions. This is due to geographic isolation, limitations to the access of the area in which they live in, and the lack of quality in the service when it is needed to be provided. Therefore, the aim of this study was to analyze the quality of life of women from a quilombola community in northeastern Brazil. It is an observational, cross-sectional and descriptive study. 160 adult women were first interviewed through a form to collect a profile and then it was applied the WHOQOL Quality of Life questionnaire - bref. It was observed that the women were on average 40.7 years old (±17.25), married, self-declared black, who did not finish elementary school, housewife, had no income, with their own masonry house, with up to 6 rooms, supplied by a box of community treated water. Quality of Life had median scores in the domains: physical (3.18), psychological (3.4), social relationships (3.45) and environment (2.59). With this research, it was possible to characterize the quilombola community of Santa Luzia do Norte-AL regarding the difficulties of access to health and income generation, issues that affect their health condition. The problems described in this study can contribute to health actions being planned and carried out in order to improve socioeconomic and health conditions in this community, considering the social, political and environmental context, valuing their traditional knowledge and practices.


Resumo As comunidades quilombolas, estão presentes em diversos estados brasileiros, vivendo em condições de saúde mais precárias. Isto ocorre por conta do isolamento geográfico, das limitações de acesso e da falta de qualidade no serviço quando este é prestado. Nesse sentido, o objetivo do estudo foi analisar a qualidade de vida de mulheres de uma comunidade quilombola do nordeste brasileiro. Estudo observacional, transversal e descritivo. Foram entrevistadas 160 mulheres adultas, através de um formulário para a coleta de perfil e do questionário de Qualidade de Vida WHOQOL - bref. Foi observado que as mulheres tinham em média 40,7 anos (±17,25), casadas, autodeclaradas negras, com fundamental incompleto, do lar, sem renda, com moradia de alvenaria, própria, com até 6 cômodos, abastecidas por caixa de água comunitária, tratada. A Qualidade de Vida, apresentou escores medianos nos domínios: físico (3,18), psicológico (3,4), relações sociais (3,45) e meio ambiente (2,59). Com a realização desta pesquisa foi possível caracterizar a comunidade quilombola de Santa Luzia do Norte-AL quanto as dificuldades de acesso a saúde e geração de renda, fatos que repercutem na sua condição de saúde.

RESUMO

Abstract Quilombola communities are present in many Brazilian states living in precarious health conditions. This is due to geographic isolation, limitations to the access of the area in which they live in, and the lack of quality in the service when it is needed to be provided. Therefore, the aim of this study was to analyze the quality of life of women from a quilombola community in northeastern Brazil. It is an observational, cross-sectional and descriptive study. 160 adult women were first interviewed through a form to collect a profile and then it was applied the WHOQOL Quality of Life questionnaire bref. It was observed that the women were on average 40.7 years old (±17.25), married, self-declared black, who did not finish elementary school, housewife, had no income, with their own masonry house, with up to 6 rooms, supplied by a box of community treated water. Quality of Life had median scores in the domains: physical (3.18), psychological (3.4), social relationships (3.45) and environment (2.59). With this research, it was possible to characterize the quilombola community of Santa Luzia do Norte-AL regarding the difficulties of access to health and income generation, issues that affect their health condition. The problems described in this study can contribute to health actions being planned and carried out in order to improve socioeconomic and health conditions in this community, considering the social, political and environmental context, valuing their traditional knowledge and practices.


Resumo As comunidades quilombolas, estão presentes em diversos estados brasileiros, vivendo em condições de saúde mais precárias. Isto ocorre por conta do isolamento geográfico, das limitações de acesso e da falta de qualidade no serviço quando este é prestado. Nesse sentido, o objetivo do estudo foi analisar a qualidade de vida de mulheres de uma comunidade quilombola do nordeste brasileiro. Estudo observacional, transversal e descritivo. Foram entrevistadas 160 mulheres adultas, através de um formulário para a coleta de perfil e do questionário de Qualidade de Vida WHOQOL bref.

RESUMO

Visceral leishmaniosis is a neglected tropical disease. We evaluated the spatial distribution of cases of visceral leishmaniosis in the state of Alagoas, Brazil. All cases of VL, registered by the health department, were analyzed and georeferenced. Results: Between 2008 and 2017, 97.1% of the municipalities presented sporadic classification of transmission. With temporal evolution, the incidence of cases of visceral leishmaniosis was concentrated in most municipalities in the microregion of Santana do Ipanema-AL. Space-time analysis, if considered, may promote the improvement of surveillance and control actions of visceral leishmaniosis.


A leishmaniose visceral é uma doença tropical negligenciada. Foram avaliadas a distribuição espacial dos casos de leishmaniose visceral no estado de Alagoas. Todos os casos de LV, registrados pela secretaria de saúde, foram analisados e georreferenciados. Entre 2008 e 2017, 97,1% dos municípios apresentaram classificação esporádica de transmissão. Com a evolução temporal, a incidência de casos de leishmaniose visceral se concentrou na maioria dos municípios da microrregião de Santana do Ipanema-AL. A análise espaço-tempo, se considerada, pode promover o aprimoramento das ações de vigilância e controle da leishmaniose visceral.
