Abstract Background Controlling blood pressure and glycemic levels is a challenge that requires innovative solutions. Objective To assess the feasibility of implementing a text message intervention among low-income primary care patients, as well as to assess self-reported behavioral change. Methods A set of 200 text messages was developed on healthy eating, physical activity, adherence, and motivation. Participants from Vale do Mucuri, MG, Brazil diagnosed with diabetes or hypertension or undergoing screening for those diseases, received 5 to 8 messages per week for 6 months. They answered a questionnaire to report their satisfaction and behavioral changes. Results Of the 136 patients, 117 (86.0%) answered the questionnaire. Most reported that the messages were very useful (86.3%), easy to understand (90.6%), and were very helpful for behavioral change (65.0%); 84.6% reported that they had started eating healthier. The most frequent reported lifestyle changes were: improved diet quality (85.5%), reduced portions (65.8%), and weight loss (56.4%). The majority of patients shared the messages (60.7%) with family or other acquaintances, considered the number of messages to be adequate (89.7%) and would recommend the program to others (95.7%). Conclusion An intervention based on text messages to promote behavioral change in patients with hypertension or diabetes in primary care is feasible in low-resource settings. Future studies are needed to assess the program’s long-term effects on clinical outcomes.

ABSTRACT Sporotrichosis is the most frequent subcutaneous mycosis in Latin America. It is caused by species of the genus Sporothrix. Infection in humans occurs through the entry of the fungus into the skin. Zoonotic outbreaks involving cats in the transmission of the disease have been frequently reported. The lymphocutaneous form is the most commonly observed and the upper limbs are the most affected sites. We report a case of a 64-year-old healthy female patient with a lymphocutaneous form with rapid progression of lesions, which was refractory to initial treatment with itraconazole. Treatment with liposomal amphotericin B was performed with a satisfactory resolution, but aesthetic and functional sequelae in the left upper limb were installed.

Abstract Oral candidiasis is a common fungal infection that affects the oral mucosa, and happens when Candida albicans interacts with bacteria in the oral microbiota, such as Streptococcus mutans, causing severe early childhood caries. C. albicans and S. mutans mixed biofilms are challenging to treat with conventional antimicrobial therapies, thus, new anti-infective drugs are required. Objective This study aimed to test a drug delivery system based on chitosan microparticles loaded with geranium and lemongrass essential oils to inhibit C. albicans and S. mutans mixed biofilms. Methodology Chitosan microparticles loaded with essential oils (CM-EOs) were obtained by spray-drying. Susceptibility of planktonic were performed according CLSI at 4 to 2,048 µg/mL. Mixed biofilms were incubated at 37ºC for 48 h and exposed to CM-EOs at 256 to 4,096 µg/mL. The antimicrobial effect was evaluated using the MTT assay, with biofilm architectural changes analyzed by scanning electron microscopy. RAW 264.7 cell was used to evaluate compound cytotoxicity. Results CM-EOs had better planktonic activity against C. albicans than S. mutans. All samples reduced the metabolic activity of mixed C. albicans and S. mutans biofilms, with encapsulated oils showing better activity than raw chitosan or oils. The microparticles reduced the biofilm on the slides. The essential oils showed cytotoxic effects against RAW 264.7 cells, but encapsulation into chitosan microparticles decreased their toxicity. Conclusion This study demonstrates that chitosan loaded with essential oils may provide an alternative method for treating diseases caused by C. albicans and S. mutans mixed biofilm, such as dental caries.

The present study investigated the use of choline chloride:glycerol deep eutectic solvent as an adjuvant for tuning the ethanol extraction of astaxanthin from Litopenaeus vannamei processing residues. The adjuvant concentration did not show a clear trend on the total carotenoid, however, the addition of adjuvant proved to be advantageous in the ultrasound-assisted experiments. In order to establish a balance between total carotenoid and productivity, an operational condition with ultrasound, 5% (m/v) choline chloride:glycerol and 10 min of incubation was selected, which provided 737.69 µg g-1 total carotenoids and 32.71 µg g-1 astaxanthin. When compared to the astaxanthin standard, the shrimp residue extract obtained greater antioxidant activity in free radical scavenging tests. In addition, the shrimp residue extract dramatically reduced the dosage of norfloxacin (up to 87.5%) and gentamicin (up to 75.0%) antibiotics in tests to inhibit the growth of Gram-negative bacteria.

RESUMO: A capacidade de produção de toxinas pelo Staphylococcus aureus no leite e produtos derivados está relacionado com surtos de intoxicação alimentar. Objetivou-se nesta pesquisa, estudar a ocorrência de genes que codificam para enterotoxinas estafilocócicas (sea, seb, sed, seg, seh e sei) e toxinas α e β hemolítica (hla e hlb) em S. aureus isolados de 53 amostras de leite de tanques expansão comunitários no Estado de Alagoas, Brasil. Foram identificados 27 isolados (50,94%) como S. aureus pela amplificação do gene nuc. 13/27 isolados (48,1%) foram positivos para pelo menos um gene das enterotoxinas estudadas, sendo as frequências dos genes sea 33,3%, seh 18,5%, sei 11,1% e sed 7,4%; não entanto não foram identificados os genes seb e seg nestas bactérias. Para as toxinas hemolíticas, 51,9% dos isolados portavam ambos genes (hla e hlb), sendo a frequência para o gene hla de 81,5% e para o gene hlb de 51,9%. A frequência de genes das toxinas avaliadas é alta o que constitui um risco potencial para a saúde pública em especial, as enterotoxinas por serem termoestáveis e estarem asssociados com surtos de intoxicação alimentar.

ABSTRACT: The capacity of toxin production by Staphylococcus aureus in milk and dairy products is associated with food poisoning outbreaks. The objective of this research was to study the frequency of genes encoding staphylococcal enterotoxin (sea, seb, sed, seg, seh and sei) and α and β hemolytic toxins (hla and hlb) in S. aureus isolates from 53 milk samples from community tanks in the State of Alagoas, Brazil. Twenty-seven isolates (50.94%) were identified as S. aureus by nuc gene amplification; 13/27 isolates (48.1%) were positive for at least one gene of the studied enterotoxins and the frequency of genes sea was 33.3%, seh 18.5%, sei 11.1% and sed 7.4%; the seb and sec genes have not been identified in the bacteria. For the hemolytic toxins, 51.9% of isolates harbored both genes (hla and hlb), the frequency of hla gene was 81.5% and 51.9% for the hlb gene. The evaluated toxin-encoding gene frequency is high and constitutes a potential risk for public health, especially staphylococcal enterotoxin genes; because they are heat-stable enterotoxins and have been associated with food poisoning.

ABSTRACT Objectives To assess the evolution to permanent or transient conditions in children with positive neonatal TSH tests in Sergipe, Brazil, from 2004 to 2010. Subjects and methods Out of 193,794 screened newborns, 713 presented a neonatal TSH level higher than the local cutoff (5.2 µU/mL). From the confirmatory serum TSH values, the children were diagnosed with initial congenital hypothyroidism (CH) or suspect CH. From the evolution, they were classified as permanent CH, hyperthyrotropinemia, or transient TSH elevation. The mean incidence of each final condition was calculated for the total period of time. Results The initial diagnosis included 37 CH (18.1%) and 167 suspect CH (81.9%) cases. The final diagnosis included 46 cases of permanent CH (22.5%), 56 of hyperthyrotropinemia (27.5%), and 102 of transient TSH elevation (50.0%). Out of the 37 cases of initial CH, 23 (62.2%) had permanent CH, nine (24.3%) had hyperthyrotropinemia, and five (13.5%) had transient TSH elevation. Out of the 167 suspect CH cases, 23 (13.8%) had permanent CH, 47 (28.1%) had hyperthyrotropinemia and 97 (58.1%) had transient TSH elevation. The mean incidence after the follow up was 1:4,166 for permanent CH, 1:3,448 for hyperthyrotropinemia, and 1:1,887 for transient TSH elevation. Eighty-six percent of the children with an initial diagnosis of CH and 41.9% with suspect CH had a permanent condition (CH or hyperthyrotropinemia). Conclusions The follow-up of children with an initial diagnosis of CH or suspect CH is necessary to determine whether the disorder is permanent because predicting the evolution of the condition is difficult.

O mormo é uma enfermidade infecto-contagiosa de caráter agudo ou crônico que acomete principalmente os equídeos, causando enormes prejuízos na cadeia produtiva do cavalo. Para controlar a enfermidade o Ministério da Agricultura, Pecuária e Abastecimento (MAPA) instituiu medidas sanitárias obrigatórias em todo território nacional que incluem o diagnóstico oficial pela fixação do complemento (FC), maleinização e sacrifício dos animais positivos. Os kits atuais utilizados no diagnóstico da doença são importados, dificultando e encarecendo sua aplicação na rotina. Objetivou-se com este estudo padronizar um teste de ELISA indireto utilizando o extrato protéico de Burkholderia mallei isolada a partir de equídeo portador no estado de Pernambuco. As amostras foram cultivadas em ágar sangue 10%, incubada por 48h a 37°C; posteriormente caracterizou-se fenotípica e genotipicamente uma das colônias isoladas, e em seguida a cultivou em BHI para enriquecimento; logo após, esta foi repicada para o meio Dor-set Henley o qual foi incubado a 37ºC sob 60rpm por oito semanas. Para padronização do teste utilizou-se o Conjugado Proteína G Peroxidase Sigma na diluição de 1:90.000, com soros diluídos em 1:100 e o antígeno em 1:400. Utilizou-se 60 soros como controle negativo testados frente à FC para determinação do ponto de corte o qual ficou em 0,042nm. Feitas as padronizações, foram testadas 300 amostras, onde 99% (297) foram concordantes com os resultados obtidos na FC. Ao final, o ensaio apresentou 100% de sensibilidade e 98,2% de especificidade com valores preditivo positivo e negativo de 97,7% e 100%, respectivamente. O teste de concordância kappa foi 0,98 e a repetibilidade intra e interplaca ficaram em 8,8 e 10,3%, respectivamente. Diante dos resultados obtidos durante os ensaios, conclui-se que o teste de ELISA indireto pode ser utilizado como uma ferramenta de diagnóstico eficiente. Entretanto, mais ensaios devem ser realizados visando consolidar a confiabilidade do referido teste.

Glanders is an infectious-contagious disease of acute or chronic character which principally affects horses, causing enormous losses in the productive chain of this animal. To control the disease, the Ministry of Agriculture, Husbandry and Supply instituted mandatory sanitation measures in the entire national territory which include an official diagnosis through the complement fixation (CF) test, maleinization and sacrifice of the animals that are positive. Nowadays the kits used for the diagnosis of the disease are imported, making their routine application difficult and more expensive. The objective of this study was to standardize an indirect ELISA test, using the proteic extract of Burkholderia mallei isolated from a carrier horse in the state of Pernambuco. The samples were cultivated in 10% blood agar and incubated for 48h at 37°C; later, one of the isolated colonies was characterized phenotypically and genotypically and immediately cultivated in brain heart infusion (BHI) for enrichment; then it was peaked (repicada) for the Dor-set Henley medium which was incubated at 37ºC under 60rpm for eight weeks. To standardize the test the Protein G Peroxidase Sigma Conjugate was used in the dilution of 1:90.000, with serums diluted in 1:100 and the antigen in 1:400. Sixty serums were used as negative controls, tested before the CF to determine the cutting point which was 0.042nm. After establishing the standardization, 300 samples were tested, of which 99% (297) were in agreement with the results obtained in the CF. At the end, of assay presented 100% sensibility and 98.2% specificity, with predictive (preditivo) positive and negative values of 97.7% and 100% respectively. The Kappa concordance test was 0.98 and the intra and interplac repeatability were 8.8% and 10.3% respectively. From the results obtained, it is possible to affirm that the indirect ELISA test can be used as an efficient diagnosis tool. However, more essays must be carried out to consolidate the reliability of this test.

As características físicas e hidráulicas do solo se constituem em condicionantes a planos de manejo agrícola. Objetivou-se avaliar atributos físicos em solos de um vale aluvial e sua variabilidade, no semiárido do Estado de Pernambuco, na bacia hidrográfica do Rio Ipanema. Técnicas estatísticas e geoestatísticas foram utilizadas a fim de se investigar o grau de dependência e a variabilidade espacial dos atributos, em lotes de agricultura familiar. O coeficiente de variação apresentou-se alto para a condutividade hidráulica do solo e médio para a resistência à penetração de raízes e para as frações granulométricas areia, argila e silte. Tal coeficiente foi baixo para a densidade do solo e de partículas e porosidade total. Foram investigadas as estruturas de dependência espacial para as variáveis estudadas, encontrando-se alcances variando de 135 m para a condutividade hidráulica a 465 m para o conteúdo de silte. Mapa de isolinhas foi elaborado por krigagem representando a variabilidade espacial da condutividade hidráulica, com moderado grau de dependência espacial. As frações granulométricas areia total e silte (%) também apresentaram grau de dependência espacial moderado. A resistência à penetração, densidade do solo e de partículas, não apresentaram dependência espacial na escala de investigação adotada. Foi possível identificar regiões de maior aptidão agrícola verificando-se, através do mapeamento, que os solos francos tendem a apresentar elevada resistência à penetração e baixa condutividade hidráulica.

Soil physical and hydraulic characteristics are relevant for agricultural management, particularly at irrigation districts. The objective of this study was to evaluate the spatial variability of physical attributes of soil in an alluvial valley in the semiarid region of Pernambuco State, at the Ipanema River Watershed. Statistical techniques and geostatistics were applied to observe the degree of dependence and the spatial variability of soil physical properties, in plots adopted for communal agriculture. The coefficient of variation for the hydraulic conductivity was high, medium for soil resistance to root penetration and for sand, clay and silt. For bulk density, particle density and porosity, however, such coefficient was low. Spatial dependence structures were investigated, with ranges spanning from 135 m, for soil hydraulic conductivity, to 465 m, for silt content. Contour map was produced by kriging interpolation, representing the spatial variability of hydraulic conductivity, which showed moderate spatial dependence. Resistance to root penetration, soil density and particle distribution presented spatial random behavior, for the adopted spatial scale. It was possible to identify regions with higher agricultural potential. From the produced map, it was highlighted that loam soils usually present higher resistance to root penetration, and low hydraulic conductivity.

OBJETIVO: Analisar o perfil das internações hospitalares por doenças respiratórias em crianças e adolescentes na cidade de São Paulo (SP). MÉTODOS: Estudo ecológico de séries temporais. Foram obtidas informações sobre internações hospitalares por doenças respiratórias (Código Internacional de Doenças, 10ª Revisão: J00-J99) em hospitais conveniados ao Sistema Único de Saúde, localizados na cidade de São Paulo, entre 2000 e 2004. Foram descritas as principais características de distribuição temporal, por faixa etária e por causa de morbidade respiratória na infância e na adolescência. RESULTADOS: As pneumonias e broncopneumonias (51%), a asma (18%) e as doenças agudas e crônicas das vias aéreas superiores (10%) responderam pela maior parte das internações. As crianças até cinco anos são as mais internadas, independentemente da causa específica. Entre os adolescentes, observou-se que as principais causas de internações foram as doenças respiratórias que afetam o interstício pulmonar (0,1%) e as afecções necróticas e supurativas das vias aéreas inferiores (0,2%). Na faixa etária de seis a dez anos, predominam as internações por doenças agudas e crônicas das vias aéreas superiores (10%). Houve tendência de aumento das internações por doenças respiratórias ao longo do período analisado, além da constatação de que o pico de morbidade se dá no começo do outono. CONCLUSÕES: As internações por doenças respiratórias de crianças e adolescentes apresentam padrão de distribuição dependente da faixa etária e da sazonalidade. Quanto menor a faixa etária maior o número de internações.

OBJECTIVE: To analyze the profile of children and adolescents' hospital admissions due to respiratory diseases in São Paulo (SP), Brazil. METHODS: This is an ecological time series study. Data was obtained on hospital admissions for respiratory diseases (International Classification of Diseases, 10th Revision: J00-J99) in hospitals under the Brazilian Unified Health System located in São Paulo between 2000 and 2004. Main characteristics of the temporal distribution of respiratory morbidity in childhood and adolescence by age and cause are described. RESULTS: Pneumonia and bronchopneumonia (51%), asthma (18%) and acute and chronical diseases from upper airways (10%) accounted for most of the admissions. Children up to five years are most frequently hospitalized, regardless of the specific cause. Among adolescents, the main causes of hospitalization were respiratory diseases that affects mainly the interstitial lung (0.1%) and the necrotic and suppurative diseases of lower airways (0.2%). From the age of six to ten years, admissions for acute and chronic diseases from upper airways (10%) were predominant. The peak of morbidity occurs in early autumn. There was a trend towards increasing hospital admissions for respiratory illnesses during the analyzed period. CONCLUSIONS: The distribution of hospital admissions for respiratory diseases in children and adolescents is dependent on age and season. The younger the age the greater the number of hospital admissions.
