- Biological agents risk assessment: how to close the gap between science, policy making and occupational health and safety practice?Publication . Colomo, Carlota Alejandre; Heussen, Henri; Van der Haar, Rudolf; Marchand, Geneviève; Madsen, Anne Mette; Viegas, CarlaWithin the Occupational Hygiene community, the risk assessment due to exposure to biological agents has received little attention compared to chemical agents. However, the impact of the current COVID-19 pandemic highlights the importance of raising awareness and prioritizing the prevention of work-related health effects caused by biological agents. However, tools for inventorying hazards, performing risk assessments, implementing control measures, and anchoring the results are rare. With the COVID-19 pandemic in mind, biological agents are often only referred to as infectious diseases. However, both infectious and non-infectious microorganisms may cause health effects. Workers in various sectors, such as healthcare and veterinary services, agriculture, waste, and wastewater management, and laboratories may be exposed through aerosols or contact with infected persons or materials that are contaminated by microorganisms. Furthermore, the sensitizing and toxic effects of biological agents are not considered when they are classified into biological agent risk groups. The sensitizing biological agents include fungi and certain bacteria (including thermophile actinomycetes). Toxic effects can be caused by metabolic products and cellular constituents of biological agents. Increased focus on biological exposures and health effects is therefore needed in order to improve the risk assessment for biological agents. The evaluation of workplace bioaerosol exposure risk is complex, considering the great diversity of bioaerosols and their effects, the limitations of the measurement methods available, and the lack of occupational exposure limits. In this symposium we present the concept of a tiered biological agents risk assessment, starting with a qualitative and ending with a quantitative approach.
- Comparação da coloração de H&E com hematoxilina de Harris: protocolo convencional vs. progressivoPublication . Bernardino, Cátia; Trindade, Giulia; Caramelo, Rita; Palma, João; Borges-Ferro, AHaematoxylin and Eosin (H&E) staining is an essential technique used for the microscopic visualization of cytohistological structures. This method commonly applies Harris haematoxylin (HH) to stain basophilic structures, particularly cell nuclei. Generally, a regressive staining protocol is employed, which includes hydrochloric alcohol as a differentiator to remove excess stain. Alternatively, a progressive protocol can be used, which does not require differentiation, making it typically faster and less resource-intensive. This study aimed to determine the most efficient method for HH staining in H&E by comparing both regressive and progressive approaches. Thirty-two non-neoplastic human tissue samples were stained using the regressive protocol, as well as three variations of the progressive protocol with HH incubation times of 3, 4, and 5 minutes. Two specialists assessed the following parameters using a weighted scoring scale from 0 to 100 points: a) morphological preservation, b) intensity of nuclear staining, c) intensity of cytoplasmic staining, d) nuclear detail, and e) non-specific staining. The average scores were 94.06 ± 8.32 for the regressive protocol and 89.84 ± 10.00, 93.12 ± 8.27, and 92.13 ± 7.04 for the progressive protocols with incubation times of 3, 4, and 5 minutes, respectively. To evaluate the impact of the different protocols on staining quality, a one-way analysis of variance (ANOVA) was performed, revealing no significant differences (F(3, 124) = 1.463, p = 0.228); Tukey's post-hoc test supported this finding. These results suggest that the choice of protocol does not significantly affect staining quality, implying that other factors may contribute to variability in performance. Notably, the 3-minute progressive protocol emerged as the most efficient option, as it reduced staining time and eliminated the need for a differentiating agent while achieving results comparable to those of the regressive method. Future research should explore additional factors influencing staining quality, such as haematoxylin oxidation, and consider replicating the study with a more diverse sample set, including neoplastic tissues.
- O contributo do ortoptista na equipa de saúde em Cabo Verde: cuidados de saúde terciáriosPublication . Fernandes, NádiaDeficiência visual: a) cegueira: para casos de perda total de visão ou quando o indivíduo tem de confiar predominantemente nas habilidades de substituição de visão; b) baixa visão: para casos de menor grau de perda de visão, em que o indivíduo pode melhorar o seu desempenho visual através de ajudas. O indivíduo com baixa visão é aquele que apresenta diminuição do funcionamento visual, mesmo após tratamento e/ ou correção óptica convencional, e tem uma acuidade visual menor que 0.33 a percepção luminosa, ou um campo visual inferior a 10º do seu ponto de fixação, mas que utiliza ou é potencialmente capaz de utilizar a visão para o planeamento e/ou execução de uma tarefa em que a visão é essencial.
- Deficiência visual e reabilitação: workshopPublication . Fernandes, NádiaCegueira = perda total. Baixa visão = perda parcial. “More people are blinded by definition than by any other cause” (Colenbrander, 2010).
- ExotropiasPublication . Lino, PedroEstrabismo - Síndroma oculomotora com duas componentes motora e sensorial. Na componente motora um dos olhos encontra se desviado, estando numa posição anómala face ao outro, dito dominante. Na componente sensorial existe alterações da visão binocular de modo a que as imagens não se formam em pontos retinianos correspondentes o que leva ao desenvolvimento de fenómenos sensoriais subsequentes e/ou compensatórios. Exotropia - Desvio temporal dos eixos visuais. Exotropia intermitente X(T): representa a forma mais comum de exodesvios. Prevalência estimada 60 em crianças com desenvolvimento normal. Exotropia constante: desvio divergente permanente dos eixos visuais XT congénita, XT secundária (sensorial), XT secundária a uma X(T) descompensada.
- A health promotion protocol to prevent age-related macular degeneration progression: the roles of vitamin D and polyphenolsPublication . Fernandes, NádiaAge-related macular degeneration (AMD) is a chronic progressive ocular disease that causes central vision loss, it is responsible for 8.7% of blindness worldwide, and it is the main cause of visual impairment in developed countries in individuals aged over 60 years, and its incidence is variable late AMD is higher in Europe (0.14%) and in America (0.35%). The prevalence of AMD is increasing due to the growth of the aging population Thus, health promotion and preventive medicine are essential tools to reduce the risk of visual impairment.
- Impact of high-performance sport on serum potassium values in athletes: a systematic reviewPublication . Tavares, Ana Sofia; Vieira, Daniela; Pires, Mariana Midões; Miranda, Vasco; Bellém, FernandoBackground: Potassium is an alkali metal and the most abundant cation in the body, which can be measured in serum, plasma, whole blood, and urine without preservatives. The release of potassium from the muscles into the bloodstream during intense exercise is related to the intensity of physical activity. Therefore, changes in the serum levels of potassium measured in the blood of individuals who practice sports regularly can have consequences for the performance and health of athletes. Aims: The present systematic review aims to analyze studies that investigate the impact of training on serum potassium levels in athletes. Method: The PRISMA guidelines were followed and 12 articles were included using electronic databases such as PubMed, Scopus, and Web of Science, and the search was carried out between April 21 and June 15, 2022. Primary research articles written in Portuguese, English, and Spanish have included the study population as athletes who did not take potassium supplements. Results: According to the results obtained, 7 of the 12 articles demonstrate an increase in potassium levels during exercise and a decrease after exercise. Thus, no definitive conclusion can be taken, and it is necessary to deepen this theme more individually to later make a better association between sports. Conclusion: Future studies should be conducted to understand the effect of changes in potassium levels in the heart muscle due to the spurious correlation between potassium and cardiac arrest.
- Impact of non-therapeutic doses of anabolic steroids on glucose and insulin levels in male bodybuilders: systematic reviewPublication . Tavares, Ana Sofia; Ferreira, Bárbara; Leite, Beatriz; Calixto, Carolina; Bellém, FernandoBackground: Anabolic androgenic steroids (AAS) are synthetic compounds with a chemical structure similar to testosterone. Bodybuilders frequently use them to increase muscle mass, and strength, and reduce body fat. However, AAS can also have adverse effects on health, including alterations in glucose and insulin levels. Aims: This systematic literature review aimed to collect and critically analyze studies that describe the impact of AAS use, in non-therapeutic doses, on glucose and insulin levels in male bodybuilders. Method: The PRISMA guidelines were followed, and four articles were included using electronic databases such as PubMed, Scopus, and Web of Science. Results: The analyzed studies present results of insulin and glucose measurements in an interventional group and a control group, showing that AAS can influence these levels. AAS may decrease insulin sensitivity, which can increase the risk of developing type 2 diabetes. Conclusion: Bodybuilders AAS´s users should have professional counseling about the negative health impact of these substances and be subject to regular check-ups to check their health status.
