Resumo A Atenção Primária à Saúde (APS) é considerada imprescindível para a efetividade dos sistemas de saúde. O objetivo deste estudo foi avaliar a qualidade da assistência prestada na APS em um município de Pernambuco. Realizou-se um estudo exploratório através da escuta a 525 usuários utilizando questionários estruturados. A avaliação da qualidade considerou as dimensões: acessibilidade, assistência clínica, relação profissional-usuário, atividades comunitárias e estrutura. Os resultados apontam para um contexto de perpetuação das vulnerabilidades sociais e o desafio em alcançar um atendimento equitativo e universal. Os principais aspectos de insatisfação foram: dificuldade de acesso a consultas e exames especializados, tempo de espera para atendimento e possibilidade de apresentar reclamações. Por outro lado, os entrevistados apresentaram-se satisfeitos com o atendimento médico e de enfermagem, principalmente quanto ao respeito, privacidade, escuta e confidencialidade. Verificou-se que apesar dos profissionais de saúde se empenharem na prestação de um atendimento humanizado, foi evidente a fragmentação do cuidado na rede estudada, o que dificulta o seguimento adequado e oportuno ao paciente, refletindo negativamente na qualidade da assistência prestada.

Abstract Primary health care is an essential component of effective health systems. The aim of this study aim was to evaluate the quality of primary care in a city in the state of Pernambuco, Brazil. We conducted an exploratory study with 525 service users using structured questionnaires. The quality of primary care was assessed across five dimensions: accessibility, clinical care, professional-user relations, community activities and structure. The findings point to the perpetuation of social vulnerabilities and challenges in achieving equitable universal care. Dissatisfaction rates were highest in the following categories: access to specialist appointments and exams, appointment wait time, and opportunity to make complaints. However, respondents were satisfied with medical and nursing care, particularly in relation to respect, privacy, listening and confidentiality. The findings show that, although health professionals were committed to providing humanized care, fragmentation of care is evident, hampering the provision of adequate and timely follow-up and negatively affecting the quality of care.

ABSTRACTINTRODUCTION: This study aimed to determine the frequencies of bacterial isolates cultured from diabetic foot infections and assess their resistance and susceptibility to commonly used antibiotics.METHODS: This prospective study included 41 patients with diabetic foot lesions. Bacteria were isolated from foot lesions, and their antibiotic susceptibility pattern was determined using the Kirby-Bauer disk diffusion method and/or broth method [minimum inhibitory concentration (MIC)].RESULTS: The most common location of ulceration was the toe (54%), followed by the plantar surface (27%) and dorsal portion (19%). A total of 89 bacterial isolates were obtained from 30 patients. The infections were predominantly due to Gram-positive bacteria and polymicrobial bacteremia. The most commonly isolated Gram-positive bacteria were Staphylococcus aureus, followed by Staphylococcus saprophyticus, Staphylococcus epidermidis, Streptococcus agalactiae, and Streptococcus pneumoniae. The most commonly isolated Gram-negative bacteria were Proteus spp. and Enterobacterspp., followed by Escherichia coli, Pseudomonasspp., and Citrobacterspp. Nine cases of methicillin-resistant Staphylococcus aureus (MRSA) had cefoxitin resistance, and among these MRSA isolates, 3 were resistant to vancomycin with the MIC technique. The antibiotic imipenem was the most effective against both Gram-positive and Gram-negative bacteria, and gentamicin was effective against Gram-negative bacteria.CONCLUSIONS: The present study confirmed the high prevalence of multidrug-resistant pathogens in diabetic foot ulcers. It is necessary to evaluate the different microorganisms infecting the wound and to know the antibiotic susceptibility patterns of the isolates from the infected wound. This knowledge is crucial for planning treatment with the appropriate antibiotics, reducing resistance patterns, and minimizing healthcare costs.

Aims: To determine the frequency of viral pathogens causing upper respiratory tract infections in non-hospitalized, symptomatic adults in the city of Rio de Janeiro.Methods:Respiratory samples (nasal/throat swabs) were collected between August 2010 and November 2012 and real time PCR was used to detect different viral pathogens.Results:Viruses were detected in 32.1% (43/134) of samples from 101 patients. Specifically, 9% (12/134) were positive for HBoV, 8.2% (11/134) were positive for HAdV, 5.2% (7/134) were positive for HRV, and 1.5% (2/134) were positive for FLUBV or HMPV, as single infections. HRSV-A, HPIV-3, and HCoV-HKU1 were detected in one (0.75%) sample each. Co-infections were detected in 4.8% (6/134) of the samples. Peaks of viral infections were observed in March, April, May, August, and October. However, positive samples were detected all year round. Only 23.3% (10/43) of the positive samples were collected from patients with febrile illness.Conclusion:Results presented in this report suggest that respiratory viral infections are largely under diagnosed in immunocompetent adults. Although the majority of young adult infections are not life-threatening they may impose a significant burden, especially in developing countries since these individuals represent a large fraction of the working force.

Asymptomatic influenza virus infections in pigs are frequent and the lack of measures for controlling viral spread facilitates the circulation of different virus strains between pigs. The goal of this study was to demonstrate the circulation of influenza A virus strains among asymptomatic piglets in an abattoir in Brazil and discuss the potential public health impacts. Tracheal samples (n = 330) were collected from asymptomatic animals by a veterinarian that also performed visual lung tissue examinations. No slaughtered animals presented with any noticeable macroscopic signs of influenza infection following examination of lung tissues. Samples were then analysed by reverse transcription-polymerase chain reaction that resulted in the identification of 30 (9%) influenza A positive samples. The presence of asymptomatic pig infections suggested that these animals could facilitate virus dissemination and act as a source of infection for the herd, thereby enabling the emergence of influenza outbreaks associated with significant economic losses. Furthermore, the continuous exposure of the farm and abattoir workers to the virus increases the risk for interspecies transmission. Monitoring measures of swine influenza virus infections and vaccination and monitoring of employees for influenza infection should also be considered. In addition regulatory agencies should consider the public health ramifications regarding the potential zoonotic viral transmission between humans and pigs.

Four extracts from the seaweed Hypnea musciformis (Wulfen in Jacq.) J.V. Lamour. (Rhodophyta), collected directly from its natural habitat or cultivated in the presence of phytohormones, were evaluated for their ability to inhibit the replication of acyclovir-resistant herpes simplex viruses types 1 (HSV-1) and 2 (HSV-2) strains. The main purpose was to determinate whether these growth conditions would affect the antiviral activity. Our results showed the possibility of improving the anti-HSV activity by using extracts from algae cultured in the presence of phytohormones.

Neste artigo, foi avaliada a atividade antiviral da alga marinha Ulva fasciata, coletada nas Praias do Forno e Rasa, em Búzios, Rio de Janeiro, Brasil, sobre a replicação do metapneumovírus humano (HMPV). Os extratos desta alga foram preparados utilizando três diferentes metodologias, visando a comparação da atividade de diferentes grupos de compostos químicos que são obtidos dependendo da metodologia empregada. Quatro, do total de seis extratos foram capazes de inibir praticamente 100% da replicação viral. Os resultados demonstram também que a maioria dos extratos (cinco, dos seis), possui atividade virucida e, portanto, possuem a habilidade de interagir com a partícula viral extracelularmente impedindo a infecção. Por outro lado, apenas dois extratos (coletado da Praia do Forno e, preparado através de maceração e maceração do decocto) foram capazes de se ligar a receptores celulares, impossibilitando assim a entrada das partículas virais nas células. Finalmente, apenas o extrato que foi preparado por maceração da alga coletada na Praia do Forno, demonstrou atividade intracelular. Até onde sabemos, este é um estudo pioneiro sobre a atividade antiviral de algas marinhas sobre o HMPV. É também o primeiro estudo sobre atividade antiviral sobre HMPV realizado no Brasil. O estudo também mostra o efeito de diferentes condições ambientais e procedimentos químicos utilizados na preparação do extrato sobre suas propriedades biológicas.

We evaluated the antiviral activity of the marine alga, Ulva fasciata, collected from Rasa beach and Forno beach, Búzios, Rio de Janeiro, Brazil on the replication of human metapneumovirus (HMPV). The algae extracts were prepared using three different methodologies to compare the activity of different groups of chemical composites obtained through these different methodologies. Four out of the six extracts inhibited nearly 100% of viral replication. The results demonstrated that the majority of the extracts (five out of six) possess virucidal activity and therefore have the ability to interact with the extracellular viral particles and prevent the infection. On the other hand, only two extracts (from Forno beach, obtained by maceration and maceration of the decoction) were able to interact with cell receptors, hindering the viral entry. Finally, only the extract of algae collected at Forno beach, obtained by maceration presented intracellular activity. To our knowledge, this is a pioneer study on antiviral activity of marine algae against HMPV. It is also the first on antiviral activity against HMPV ever done in Brazil. The study also shows the effect of different environment factors and different chemical procedures used to obtain the extract on its biological properties.

OBJECTIVES: Natural latex does not fall into the category of materials known to be entirely inoffensive. The purpose of this in vitro study was to test the hypothesis that there is no difference in the cytotoxicity between elastics of different colors and those from different manufacturers. MATERIAL AND METHODS: Different latex intraoral elastics of different colors (5/16 = 7.9 mm, mean load) were compared. The sample was divided into 7 groups of 24 elastics each: Group T (TP Orthodontics, natural latex elastics, control); Groups U1, U2, U3, U4, U5 and U6 (Uniden, natural latex elastics and colored elastics, namely, green, pink, yellow, red and purple, respectively). Cytotoxicity assays were performed by using cell culture medium containing epithelioid-type cells (Hep-2 line) derived from human laryngeal carcinoma. The cytotoxicity was evaluated by using the "dye-uptake" test, which was employed at two different moments (0 and 24 h). Data were compared by analysis of variance (ANOVA) and Tukey's test (p<0.05). RESULTS: There was statistically significant difference (p<0.05) between Group T and all other groups (U1, U2, U3, U4, U5 and U6) at 0 and 24 h. No statistically significant difference (p<0.05) was found between Groups U1 and U5, U1 and U6, U2 and U3, U2 and U4, U2 and U5, U2 and U6, U3 and U4, U3 and U5, U3 and U6, U4 and U5, U4 and U6, and U5 and U6 at 0 and 24 h. CONCLUSIONS: The TP Orthodontics elastics promoted less cell lysis compared to the Uniden elastics regardless of their color.
