Todos os anos, milhares de pessoas morrem vítimas de doenças causadas pelo consumo de produtos derivados do tabaco, este é considerado a principal causa de morte evitável. O tabaco também colabora com as seis das oito principais causas de mortes entre fumantes e não fumantes a nível mundial. Algumas medidas governamentais como as campanhas publicitárias antitabagistas, buscam alertar, conscientizar e mudar o pensamento e o interesse coletivo neste tipo de produto e consequentemente, diminuir a taxa de consumo. Avaliar se as crenças, pensamentos e atitudes dos brasileiros são influenciados por este tipo de publicidade e se o comportamento relacionado a não fumar ou deixar de fumar é uma consequência da persuasão das mensagens antitabagistas, ajudam a conhecer o real impacto destas campanhas e sua eficácia. Através dos métodos de investigação quantitativo e qualitativo e das análises extensiva e semiótica, a pesquisa inquiriu 272 indivíduos brasileiros à respeito das advertências sanitárias e das campanhas publicitárias antitabagistas, classificando-os como não fumantes, ex-fumantes e fumantes, identificando os elementos visuais e textuais que compõem a narrativa publicitária de 5 anúncios antitabagistas. Após a análise, a pesquisa concluiu que as campanhas publicitárias coordenadas pelo INCA – Instituto Nacional de Câncer, denominadas campanhas antitabagistas, são eficazes para alertar e conscientizar os indivíduos sobre os males causados pelo consumo do cigarro mas ineficazes para influenciar suas atitudes e comportamentos. Embora estas consigam persuadir à crença nas mensagens, fazendo com que os indivíduos as vejam como verdadeira, isto não é suficiente para que a intenção de deixar de fumar torne-se um ato prático. Todos os anúncios possuem o mesmo formato e a maioria utilizou o mesmo percurso visual, equilíbrio, enquadramento, luz, ângulo e função do personagem. Todos possuem textos com funções identificadora, ancoragem e apoio e a narrativa conota o cigarro como algo negativo, prejudicial, mortífero e destruidor.

There are several hazards in histopathology laboratories and its staff must ensure that their professional activity is set to the highest standards while complying with the best safety procedures. Formalin is one of the chemical hazards to which such professionals are routinely exposed. To decrease this contact, it is suggested that 10% neutral buffered liquid formalin (FL) is replaced by 10% formalin-gel (FG), given the later reduces the likelihood of spills and splashes, and decreased fume levels are released during its handling, proving itself less harmful. However, it is mandatory to assess the effectiveness of FG as a fixative and ensure that the subsequent complementary techniques, such as immunohistochemistry (IHC), are not compromised. Two groups of 30 samples from human placenta have been fixed with FG and FL fixatives during different periods of time (12, 24, and 48 hours) and, thereafter, processed, embedded, and sectioned. IHC for six different antibodies was performed and the results were scored (0–100) using an algorithm that took into account immunostaining intensity, percentage of staining structures, non-specific immunostaining, contrast, and morphological preservation. Parametric and non-parametric statistical tests were used (alpha = 0•05). All results were similar for both fixatives, with global score means of 95•36±6•65 for FL and 96•06±5•80 for FG, and without any statistical difference (P>0•05). The duration of the fixation had no statistical relevance also (P>0•05). So it is proved here FG could be an effective alternative to FL.

Scope of study: welding operations result in harmful emissions of nanoparticles; the aim of emissions monitorisation is to evaluate exposure levels and to derive protection measures in order to protect exposed workers; however, the traditional approach of comparing measured concentrations with exposure limits cannot be used; but risk levels can be quantified by using Control Banding Strategies.

Diarrhoea is the second leading cause of death in children under five years being responsible for 760.000 deaths, corresponding to 9% of the total deaths in this age group. Africa is the region with more deaths due to diarrhoea (46%), followed by South Asia (38%). Three quarters of the total of deaths occurs within only 15 countries and Angola is in the 15th position with a record of 20,000 annual childhood deaths. Diarrhoeal disease can be caused by bacterial, viral and parasitic infectious agents and can be transmited through contaminated food or drinking water, or directly from person to person. Rotavirus and Escherichia coli were shown the most frequent pathogenic agents in developing countries. This study aims to identify the most frequent pathogenic agents of diarrhoea in children under five atttending the Bengo General Hospital (BGH)..

In slaughterhouses, the biological risk is present not only from the direct or indirect contact with animal matter, but also from the exposure to bioaerosols. Fungal contamination was already reported from the floors and walls of slaughterhouses. This study intends to assess fungal contamination by cultural and molecular methods in poultry, swine/bovine and large animal slaughterhouses. Air samples were collected through an impaction method, while surface samples were collected by the swabbing method and subjected to further macro- and micro-scopic observations. In addition, we collected air samples using the impinger method in order to perform real-time quantitative PCR (qPCR) amplification of genes from specific fungal species, namely A. flavus, A. fumigatus and A. ochraceus complexes. Poultry and swine/bovine slaughterhouses presented each two sampling sites that surpass the guideline of 150 CFU/m3. Scopulariopsis candida was the most frequently isolated (59.5%) in poultry slaughterhouse air; Cladosporium sp. (45.7%) in the swine/bovine slaughterhouse; and Penicillium sp. (80.8%) in the large animal slaughterhouse. Molecular tools successfully amplified DNA from the A. fumigatus complex in six sampling sites where the presence of this fungal species was not identified by conventional methods. This study besides suggesting the indicators that are representative of harmful fungal contamination, also indicates a strategy as a protocol to ensure a proper characterization of fungal occupational exposure.
