RESUMO

BACKGROUND: It is increasingly recognized that conventional food production systems are not able to meet the globally increasing protein needs, resulting in overexploitation and depletion of resources, and environmental degradation. In this context, microbial biomass has emerged as a promising sustainable protein alternative. Nevertheless, often no consideration is given on the fact that the cultivation conditions affect the composition of microbial cells, and hence their quality and nutritional value. Apart from the properties and nutritional quality of the produced microbial food (ingredient), this can also impact its sustainability. To qualitatively assess these aspects, here, we investigated the link between substrate availability, growth rate, cell composition and size of Cupriavidus necator and Komagataella phaffii. RESULTS: Biomass with decreased nucleic acid and increased protein content was produced at low growth rates. Conversely, high rates resulted in larger cells, which could enable more efficient biomass harvesting. The proteome allocation varied across the different growth rates, with more ribosomal proteins at higher rates, which could potentially affect the techno-functional properties of the biomass. Considering the distinct amino acid profiles established for the different cellular components, variations in their abundance impacts the product quality leading to higher cysteine and phenylalanine content at low growth rates. Therefore, we hint that costly external amino acid supplementations that are often required to meet the nutritional needs could be avoided by carefully applying conditions that enable targeted growth rates. CONCLUSION: In summary, we demonstrate tradeoffs between nutritional quality and production rate, and we discuss the microbial biomass properties that vary according to the growth conditions.

RESUMO

WHIM syndrome is an inherited immune disorder caused by an autosomal dominant heterozygous mutation in CXCR4. The disease is characterized by neutropenia/leukopenia (secondary to retention of mature neutrophils in bone marrow), recurrent bacterial infections, treatment-refractory warts, and hypogammaglobulinemia. All mutations reported in WHIM patients lead to the truncations in the C-terminal domain of CXCR4, R334X being the most frequent. This defect prevents receptor internalization and enhances both calcium mobilization and ERK phosphorylation, resulting in increased chemotaxis in response to the unique ligand CXCL12. Here, we describe 3 patients presenting neutropenia and myelokathexis, but normal lymphocyte count and immunoglobulin levels, carrying what we believe to be a novel Leu317fsX3 mutation in CXCR4, leading to a complete truncation of its intracellular tail. The analysis of the L317fsX3 mutation in cells derived from patients and in vitro cellular models reveals unique signaling features in comparison with R334X mutation. The L317fsX3 mutation impairs CXCR4 downregulation and ß-arrestin recruitment in response to CXCL12 and reduces other signaling events - including ERK1/2 phosphorylation, calcium mobilization, and chemotaxis - all processes that are typically enhanced in cells carrying the R334X mutation. Our findings suggest that, overall, the L317fsX3 mutation may be causative of a form of WHIM syndrome not associated with an augmented CXCR4 response to CXCL12.

RESUMO

RESUMO Objetivo A qualidade de vida sexual abarca a satisfação sexual e com a parceria, a expressão de desejos e valores sexuais, a boa imagem corporal, além de questões de ordem física, comportamentais, psicológicas e emocionais que afetam a sexualidade. Não há instrumentos confiáveis e válidos para avaliar a qualidade de vida sexual das mulheres brasileiras, portanto este estudo buscou traduzir o Questionnaire on Sexual Quality of Life - Female (SQoL-F) e apresentar evidências de validade do instrumento no contexto brasileiro. Métodos Foram realizados tradução, avaliação da validade de conteúdo, teste da versão pré-final e análise fatorial exploratória do instrumento. Resultados Identificou-se a presença de um único fator que explicou 49% da variância, condizente com o proposto no questionário original. Esse modelo unifatorial apresentou cargas fatoriais adequadas (entre 0,36 e 0,85). Conclusão O questionário apresentou boa consistência interna e foram apresentadas evidências de validade satisfatórias para o uso com mulheres brasileiras.


ABSTRACT Objective The quality of sexual life encompasses sexual satisfaction and with partnership, the expression of sexual desires and values, good body image, in addition to physical, behavioral, psychological and emotional issues that affect sexuality. There are no reliable and valid instruments to assess the quality of sexual life of Brazilian women, so this study sought to translate the Questionnaire on Sexual Quality of Life - Female (SQoL-F) and present evidence of validity of the instrument in the Brazilian context. Methods The translation, content validity evaluation, pre-final version test and exploratory factor analysis were performed. Results The presence of a single factor was identified that explained 49% of the variance, consistent with what was proposed in the original questionnaire. This one-factor model presented adequate factor loadings (between 0.36 and 0.85). Conclusion The questionnaire had good internal consistency and presented satisfactory evidence of validity for use with Brazilian women.

RESUMO

Post-exposure prophylaxis (PEP) is necessary to prevent the fatal onset of rabies but requires optimization to avoid overuse in populations at risk of rabies. In Brazil, the incidence of dog bites remains high, with almost half of dog-bite patients not receiving the PEP recommended by the Ministry of Health guidelines between 2008 and 2017. In this study, we aimed to identify the factors that limit the appropriate prescribing of PEP by interviewing health professionals responsible for PEP administration and completion of the 'Information System on Diseases of Compulsory Declaration' (SINAN) form reporting human anti-rabies care for patients seeking health care after a dog bite. We conducted 147 questionnaires (45 questions each) in three Brazilian states (i.e., Rio Grande do Sul, Santa Catarina, Rio Grande do Norte) including questions related to the criteria used by professionals to classify a dog as "suspect" or "rabid", knowledge on PEP prescription guidelines, SINAN and communication with veterinarians. Our analyses showed that most health professionals delivering PEP in these three states struggle to identify a rabies "suspect" dog according to the Ministry of Health guidelines, and to indicate the adequate PEP regimen, with only 11% of professionals prescribing the appropriate PEP under various dog-bite patient scenarios. PEP knowledge score was higher among professionals trained on PEP guidelines and working in facilities with the highest incidence of dog bites. In contrast, PEP knowledge scores did not vary significantly between states, and were not correlated to the professional's level of experience, the number of colleagues available at the health unit or the professional's confidence on prescribing appropriate PEP. Our results suggest that knowledge gaps in PEP administration among health professionals of Brazil can be reduced by implementing training programs to differentiate among rabies risk scenarios, prescribe the corresponding appropriate PEP and improve communication between health and veterinary authorities.

RESUMO

Canine Distemper is a disease caused by Canine morbillivirus (CM), a pantropic virus that can affect the central nervous system (CNS), causing demyelination. However, the pathogenesis of this lesion remains to be clarified. Brain samples of 14 naturally infected dogs by CM were analyzed to evaluate the presence of oxidative stress and demyelination. RT-PCR assay was performed to confirm a diagnosis of canine distemper in the brain, immunohistochemistry anti-CM was used to localize the viral proteins in the tissue, and anti-4-hydroxy-2-nonenal (4-HNE) was a marker of a product of lipid peroxidation. The results showed the presence of viral proteins in the demyelinated area with the presence of 4-HNE. Our results suggest that the CM virus infection causes oxidative stress leading to lipid peroxidation, which causes tissue damage and demyelination. In conclusion, oxidative stress plays a significant role in canine distemper pathogenesis in the CNS.(AU)


A cinomose canina é uma doença causada pelo Morbilivírus canino (CM), um vírus pantrópico que pode afetar o sistema nervoso central (SNC), causando desmielinização. No entanto, a patogênese dessa lesão não está totalmente esclarecida. RT-PCR e imuno-histoquímica foram realizadas para confirmação do diagnóstico de cinomose em amostras de encéfalo de 14 cães naturalmente infectados. Após confirmação, foi realizada uma avaliação do estresse oxidativo por imuno-histoquímica com uso de anti-4-hidroxi-nonenal (4HNE) como marcador de produtos resultantes da peroxidação lipídica. Os resultados sugerem que a infecção pelo CM causa estresse oxidativo no tecido, levando a peroxidação lipídica, a qual causa danos ao tecido, culminando com desmielinização. Conclui-se que o estresse oxidativo tem papel importante na patogênese da cinomose canina no sistema nervoso central.(AU)

RESUMO

Background and objectives. The impact of death by suicide represents an important public health issue. The current study reports data relating depressive symptoms and psychological well-being to exposure to suicide in the family. Methods. A final Portuguese community sample of 266 participants answered a protocol presented on a Google platform. Two groups were defined: a suicide exposure group (n = 45) and a control group (n = 210) who responded to the Échelle de Mesure des Manifestations du Bien-Être Psychologique (Psychological Well-being Manifestation Measure Scale) and to the Center for Epidemiologic Studies Scale to access psychological well-being and depressive symptoms, respectively. Results. roups differ significantly on psychological well-being, even when contorting for unemployment and having physical disease, differed on depressive symptoms and tended to differ on depressive symptoms when contorting for unemployment and chronic physical disease. Conclusion. Based on results, we suggest that therapeutic interventions should focus not only on reducing depressive symptoms in exposed individuals, but as well as promoting well-being. Limitations include the size of the sample and the cross-sectional nature of the design.

RESUMO

OBJECTIVES: This study tested the mediation effects of two facets of psychache - bearable and unbearable - in the relationship between exposure to suicide in the family and suicidal ideation in Portugal during the Covid-19 pandemic. METHODS: Two hundred and forty-four adults aged between 19 and 64 participated. Two groups were defined: one exposed to suicide in the family (n = 42) and a control group (n = 192). RESULTS: Path analysis using structural equation modelling tested a mediation model. Results demonstrated that unbearable psychache fully mediated the relationship between exposure to suicide and suicidal ideation, even when controlling for the mediation effects of depressive symptoms, the presence of a psychiatric diagnosis, and years of education. CONCLUSIONS: These results suggest that rather than considering just the global experience of psychache in individuals exposed to suicide, researchers and clinicians should look to the presence of unbearable psychache given its contribution to suicidal ideation. PRACTITIONER POINTS: Unbearable psychache fully mediated the relationship between exposure to suicide in the family and suicidal ideation It is not the global experience of psychache that contributes to suicide ideation in individuals exposed to suicide in the family rather the presence of unbearable psychache.

RESUMO

BACKGROUND: Epidemiological surveillance of a nursing diagnosis is an approach anchored in a post-modern epidemiology focused on a person's health disease responses. Regarding public health priorities, the population where our study occurred had as a priority problem arterial hypertension. Related to this chronic disease, nursing diagnoses about health disease responses in primary healthcare has, as a major focus, Therapeutic Regimen Management. Our aim was to study the nursing diagnosis in this issue from an epidemiological approach. METHODS: A descriptive study from an epidemiological approach was developed, analyzing nursing diagnoses in hypertensive patients. RESULTS: We found 17.7% of undiagnosed patients and better diagnoses in patients with complications than in those without complications. CONCLUSIONS: Nursing records need to be improved in order to promote more robust studies in the post-modern epidemiology for the future.

RESUMO

Squamous cell carcinomas (SCC) are one of the most common tumors of the tegument that can have a misdiagnosis of chronic skin wounds. An adult captive crowned solitary eagle presented an indolent wound-like ulcer on the footpad and a fatal outcome. An infiltrating tumoral mass in the foot and multiple tumoral metastatic nodules in visceral organs were detected. The neoplasm was composed of atypical squamous cells with strong positivity for cytokeratin, "keratin pearl" structures, and marked invasion of tissues confirming a diagnosis of metastatic SCC. This might be the first report of an SSC with metastasis on the footpad in a captive Chaco eagle, which is one of the endangered species of birds of prey.

RESUMO

Over the last 20 years, substantial knowledge has been developed in Veterinary oncology, and tumors previously reported only in humans have been identified in animals. Primary paragangliomas of the tongue are extremely rare tumors in human beings and have never been reported in animals. A Chow Chow dog showed an ulcerated nodule at the lingual body, deeply infiltrated, which extended to the base of the tongue. A full clinical and pathological investigation was conducted, and a post-surgical follow-up of 6 months did not detect recurrence. Cytological, histological, and immunohistochemical features are presented and support the diagnosis of lingual paraganglioma. The paraganglioma of the tongue reported in this Chow Chow dog shares many similarities with the human counterpart.

RESUMO

Community empowerment can be a process, but also the result of nursing care. To analyze it as a result there is an instrument that allows to quantify its level in nine domains. According to Melo (2020), health centers can be considered communities, becoming the potential target of community and public health nurses care, especially in the public health unit. One of the main functions of a public health unit is the epidemiological surveillance of the population's health state. However, traditional epidemiological surveillance is focused on diseases and Melo (2020) proposes a new approach for epidemiology focused on people in what concerns nursing diagnosis. The aim of this research is to identify the level of empowerment of four Portuguese primary healthcare structures, named as ACeS, so as to improve the epidemiological surveillance of nursing diagnoses. As methodology, we developed four focus group with all nursing leaders from all primary care units of the four ACeS, using the Portuguese version of the empowerment assessment rating scale. The results present the level of community empowerment of each ACeS according to the nine domains of the scale. The needs of intervention to improve the ACeS empowerment were also identified in order to develop the epidemiological surveillance of nursing diagnoses.

RESUMO

BACKGROUND: Satisfaction with care is an important outcome measure in end-of-life care. Validated instruments are necessary to evaluate and disseminate interventions that improve satisfaction with care at the end of life, contributing to improving the quality of care offered at the end of life to the Portuguese population. The purpose of this study was to perform a cross-cultural adaptation and psychometric analysis of the Portuguese version of the CANHELP Lite Bereavement Questionnaire. METHODS: Methodological research with an analytical approach that includes translation, semantic, and cultural adaptation. RESULTS: The Portuguese version comprised 24 items. A panel of experts and bereaved family members found it acceptable and that it had face and content validity. A total of 269 caregivers across several care settings in the northern region of Portugal were recruited for further testing. The internal consistency analysis of the adapted instrument resulted in a global alpha value of 0.950. The correlation between the adapted CANHELP questionnaire and a global rating of satisfaction was of 0.886 (p < 0.001). CONCLUSIONS: The instrument has good psychometric properties. It was reliable and valid in assessing caregivers' satisfaction with end-of-life care and can be used in both clinical and research settings.

RESUMO

Introduction: To assess the level of community empowerment, Laverack proposes an instrument called the Empowerment Assessment Rating Scale (EARS), which has nine assessment domains related to community empowerment. Objectives: Translate to Portuguese and culturally validate the EARS for an ACeS community, a hospital community, a business community, and a school community. A review of the Portuguese translation was developed, a review group was set up to analyze the resulting document, by consensus a new scale called the Escala de Avaliação do Empoderamento Comunitário (EAvEC) was developed, and the retroversion was developed. Same review group conducted a new evaluation of the resulting version, comparing them with the original in English. The study was carried out at a Hospital in the Azores Archipelago, three Health Centers Organizations in the North of Portugal, an Education-oriented Company in Greater Porto and a School Community in Mozambique, where the focus group scale was applied based on a problematic chosen for intervention. Results: EVaEC retained the nine evaluation domains of the original scale and its translated version did not change after its cultural adaptation. The level of community empowerment was identified in each of the communities, analyzed in the form of a radar chart, with the clustered image of all domains. Discussion / Conclusions: EVaEC is a useful tool for community intervention and is being used to assess community empowerment in the MAIEC project of theCentre for Interdisciplinary Research in Health at Universidade Católica Portuguesa

RESUMO

Shrinking natural habitats exposes some non-human primates to the risk of accidents associated with electrical transmission lines. We examined dead marmosets (Callithrix penicillata) collected in the region from January 2015 to April 2018 to determine the animals' cause of death and for electrocuted animals we examined the locations the animals had died as well as the configuration of the power lines at these sites. We also recorded the sex of the animal, the body region affected, and characteristics of the injuries. We diagnosed electrocutions in 11% (n = 34) of the marmosets studied. Most of the affected animals were male (n = 22) with single or double sites of injury on the limbs. Animals were injured in urban (n = 26) and peri-urban (n = 8) areas on lower-voltage alternate current lines, and we detected no seasonality or hotspots of electrocution. Our findings suggest that movement along transmission lines composed of bundled conductors is a major factor in electrocutions of marmosets in the Federal District and surrounding areas. The planning of electrical power grid infrastructure should consider arboreal primates to prevent electrocutions.

RESUMO

The aim of this study was to develop a fast, effective, and material sparing screening method to design amorphous solid dispersions (ASDs) of etravirine to drive more effectively the development process, leading to improved bioavailability (BA) and stability. A systematic step-by-step approach was followed by combining theoretical calculations with high-throughput screening (HTS) and software-assisted multivariate statistical analysis. The thermodynamic miscibility and interaction of the drug in several polymers were predicted using Hansen solubility parameters (δ). The selected polymers were evaluated by HTS, using solvent evaporation. Binary compositions were evaluated by their solubilization capacity and physical stability over 2 months. JMP 14.0 was used for multivariate statistical analysis using principal components analysis. Extrusion was performed in Thermo Scientific HAAKE MiniLab II, and extrudates were characterized by assay, related substances, dissolution, and physical state (polarized light microscopy (PLM), Raman spectroscopy, and X-ray powder diffraction (XRPD)). A short stability study was performed where milled extrudates were exposed to 25 °C/60%RH and 40 °C/75%RH for 3 months. Through thermodynamic predictions, five main polymers were selected. The HTS enabled the evaluation of 42 formulations for solubilization capacity and physical stability. The three most promising compositions were selected for hot-melt extrusion (HME) tests. In general, a good correlation was found among the results of theoretical predictions, HTS, and HME. Poly(vinylpyrrolidone) (PVP)-based formulations were shown to be easily extrudable, with low degradation and complete amorphicity, whereas in Soluplus, the drug was not miscible, leading to a high crystalline content. The drug release rate was improved more than two times with PVP, and the manufactured ASD was demonstrated to be stable physically and chemically. A fast and effective screening technique to develop stable ASDs for a poorly soluble drug was successfully developed as applied to etravirine. The given method is easy to use, requires a low amount of drug, and is fairly accurate in predicting the amorphization of the drug when formulated. The success of HME formulation development of etravirine was undoubtedly enhanced with this high-throughput tool, which led to the identification of extrudates with improved biopharmaceutical properties. The structural characterization performed by PLM, XRPD, and Raman spectroscopy demonstrated that the HME prototype was essentially amorphous. The unexpected stability at 40 °C/75%RH was correlated with the presence of molecular interaction characterized by Raman spectroscopy.

RESUMO

Abstract Endodontic infections result from oral pathogenic bacteria which reach and infect dental pulp, as well as surrounding tissues, through cracks, unrepaired caries and failed caries restorations. This study aims to determine the chemical composition of essential oil from Psidium cattleianum leaves (PC-EO) and to assess its antibacterial activity against endodontic bacteria. Antibacterial activity of PC-EO was evaluated in terms of its minimum inhibitory concentration (MIC) values by the broth microdilution method on 96-well microplates. Bacteria Porphyromonas gingivalis (MIC = 20 µg/mL), Prevotella nigrescens (MIC = 62.5 µg/mL), Fusobacterium nucleatum (MIC = 12.5 µg/mL), Actinomyces naeslundii (MIC = 50 µg/mL), Bacteroides fragilis (MIC = 12.5 µg/mL), Aggregatibacter actinomycetemcomitans (MIC = 6.25 µg/mL) and Peptostreptococcus anaerobius (MIC = 62.5 µg/mL) were evaluated and compared to chlorhexidine dihydrochloride (CDH), the positive control. PC-EO was obtained by hydrodistillation with the use of a Clevenger-type apparatus whereas its chemical composition was analyzed by gas chromatography-flame ionization detection (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Viridiflorol (17.9%), β-caryophyllene (11.8%), 1,8-cineole (10.8%) and β-selinene (8.6%) were the major constituents found in PC-EO, which exhibited high antibacterial activity against all endodontic pathogens under investigation. Therefore, PC-EO, a promising source of bioactive compounds, may provide therapeutic solutions for the field of endodontics.

RESUMO

Background: While evidence demonstrates that end-of-life care practices vary across countries, there is still a lack of evidence regarding the healthcare that is received by adult individuals in the last months of life in Portugal. Methods: This is a systematic review that aims to examine the evidence published until 2019 regarding the healthcare received by adult individuals in the last months of life in Portugal. Results: Nine studies were included in this review. All of these were quantitative and retrospective studies, used patient records as the source of information, and were conducted in hospital settings. The time frame analysis before death ranged from 48 h to 3 months. The majority of the studies focused on the physical aspects of care, such as physical needs assessment and symptom management, prescribed medication, and invasive interventions. No evidence was found regarding spiritual, psychological, social or cultural needs. Conclusion: Although using patient records as a source of information may introduce a bias, this study indicates that there is a greater emphasis on the physical aspects of care and less on the psychological, spiritual or social aspects of care received by adult individuals in their last months of life in Portugal.

RESUMO

Until recently, the main goal of chronic myeloid leukemia therapy was disease control with the best overall survival, which required lifelong treatment. However, currently, the treatment-free remission concept is becoming an important goal in clinical practice, and several tyrosine kinase inhibitors discontinuation studies have shown that round 50% of patients with a durable deep molecular response beyond major molecular response successfully interrupt tyrosine kinase inhibitors for at least three years without loss of molecular response. However, and regardless of the existing evidence, the exact conditions for attempting treatment-free remission remain poorly defined. Different authors tried to guide the clinical decision regarding this topic but there are some points that differ, namely with respect to the recommended duration of tyrosine kinase inhibitors therapy and the appropriate molecular response prior to treatment-free remission. The goal of this article is to propose an algorithm to guide clinical practice in Portugal concerning chronic phase-chronic myeloid leukemia patients who wish to attempt treatment-free remission, since there are no national guidelines.


Até recentemente, o objectivo principal do tratamento da leucemia mielóide crónica era o controlo da doença com o maior tempo possível de sobrevivência, o que requeria tratamento durante toda a vida. No entanto, e actualmente, o conceito de remissão livre de tratamento está a tornar-se um objectivo importante na prática clínica, e vários estudos de descontinuação de inibidores de tirosina cinase mostraram que cerca de 50% dos doentes com uma resposta molecular profunda duradoura, para além da resposta molecular major, interrompem tratamento com inibidores de tirosina cinase com sucesso durante pelo menos três anos sem perda da resposta molecular. No entanto, e apesar da evidência existente, as condições concretas e exactas para tentar remissão livre de tratamento são ainda pouco conhecidas. Diferentes autores tentaram guiar a decisão clínica sobre este tópico mas alguns pontos permanecem não consensuais, nomeadamente no que respeita à duração recomendada de tratamento com inibidores de tirosina cinase e à resposta molecular apropriada antes de tentar remissão livre de tratamento. O objectivo desta publicação é propor um algoritmo que permita guiar a prática clínica em Portugal relativa a doentes com leucemia mielóide crónica ou em fase crónica que pretendam tentar remissão livre de tratamento, dada a ausência de recomendações nacionais.

RESUMO

Actinomycosis is a very rare infection in wild animals with a few reports in captive non-human primates. Herein we report a case of pulmonary actinomycosis in a free-living black-tufted marmoset in the urban area of the Federal District, Brazil. The animal presented severe dyspnea and died in the garden of a residence. At necropsy, the left-pulmonary lobes showed multiple nodules filled with purulent content. A myriad of beaded, branching, filamentous Gram-positive and modified Ziehl-Neelsen-negative bacilli arranged in aggregates or star-like colonies, surrounded by macrophages, neutrophils, and Splendori-Hoepli phenomenon were observed in histological sections of the lungs. According to the pathological findings and characteristic morphotintorial pattern of the infectious agent, pulmonary actinomycosis was diagnosed. Until now, fatal pulmonary actinomycosis had never been reported in free-living Simiiformes. Knowledge about the diseases that affect commensal free-range simians in urban areas forms the basis for actions aimed at conservation of the species.

RESUMO

BACKGROUND: The narrow link between practice, education, and research is essential to palliative care development. In Portugal, academic postgraduate publications are the main booster for palliative care research. METHODS: This is a bibliometric study that aims to identify Portuguese palliative care postgraduate academic work published in electronic academic repositories between 2000 and 2015. RESULTS: 488 publications were identified. The number of publications has increased, especially in the last five years. The most frequently used method was quantitative, healthcare professionals were the most studied participants, and psychological and psychiatric aspects of care comprised the most current theme. Practice-based priorities are financial costs and benefits of palliative care, awareness and understanding of palliative care, underserved populations, best practices, communication, and palliative care in nonhospital settings. CONCLUSION: The number of palliative care postgraduate academic publications has increased in Portugal in the past few years. There is academic production in the eight domains of quality palliative care and on the three levels of recommendation for practice-based research priorities. The major research gaps in Portugal are at the system and societal context levels.
