[Evaluation of microbial growth on single-use vitrectomy probes reprocessed in healthcare practice]. / Avaliação do crescimento microbiano em sondas de uso único para vitrectomia reprocessadas na prática assistencial.

The aim of this study was to evaluate the microbial growth on single-use vitrectomy probes reprocessed in healthcare practice. We investigated nine vitrectomy probes that had been reused and reprocessed using different methods. The samples were sectioned, individually, in portions of 3.5 cm, totaling 979 sampling units (extensions, connectors and vitrectomy cutters), which were inoculated in culture medium and incubated at 37º C for 14 days. The results showed microbial growth on 57 (5.8%) sample units, 25 of which had been sterilized using ethylene oxide, 16 by hydrogen peroxide plasma, and 16 by low-temperature steam and formaldehyde. Seventeen microbial species were identified. The most prevalent were: Micrococcus spp., coagulase-negative Staphylococcus, Pseudomonas spp., and Bacillus subtilis. The reuse of single-use vitrectomy probes was shown to be unsafe, therefore this practice is not recommended.

Antiretroviral therapy use in selected countries in Latin America during 2013-2017: results from the Latin American Workshop in HIV Study Group.

OBJECTIVE: To document antiretroviral use in Latin America during the last decade. METHODS: We collected indicators from 79 HIV health care centres in 14 Latin American Spanish-speaking countries for 2013-2017. Indicators were analysed by age, sex and other characteristics and weighted by the estimated people under care (PUC) population in each country. RESULTS: We gathered information on 116 299 PUC. One-third belonged to centres reporting a shortage of at least one antiretroviral therapy (ART) drug for >30 days during 2017. At end 2017, 95.1% of PUC were receiving ART. During 2013-2017, 45 329 people living with HIV were admitted to 39 centres. ART initiated during the first year after admission increased from 76.7% in 2013 to 83.8% in 2017. In 35 centres across the study period, 71.7% of PUC started ART with tenofovir disoproxil fumarate and lamivudine, and zidovudine use decreased. The third most common ART drug, EFV, reached 64.8%. Raltegravir and other alternatives increased annually to almost 10% of total use in 2017. CONCLUSIONS: Initial ART in Latin America is not based on the most recent scientific evidence and recommendations; use of drugs with higher efficacy and safety profiles and guarantee of ART availability continues to be a public health challenge.

Nursing care management in substitutive renal therapy in patients with COVID-19: integrative review / Gestión de Cuidados de Enfermería en Terapia Renal Sustitutiva en Pacientes con COVID-19: Revisión Integradora

Spray Freeze-Drying as an Alternative to the Ionic Gelation Method to Produce Chitosan and Alginate Nano-Particles Targeted to the Colon.

Chitosan and alginate nano-composite (NP) carriers intended for colonic delivery containing prednisolone and inulin were obtained by two processes. Spray freeze-drying using chitosan (SFDC) or alginate (SFDA) was proposed as an alternative to the traditional chitosan-tripolyphosphate platform (CTPP). NPs were fully characterised and assessed for their yield of particles; level of prednisolone and inulin release in phosphate and Krebs buffers; and sensitivity to degradation by lysozyme, bacteria and faecal slurry. NPs based on chitosan showed similar properties (size, structure, viscoelastic behaviour), but those based on SFDC showed a higher mean release of both active ingredients, with similar efficiency of encapsulation and loading capacity for prednisolone but lower for inulin. SFDC was less degraded in the presence of lysozyme and E. coli and was degraded by B. thetaiotaomicron but not by faecal slurry. The results obtained with SFDA were promising because this NP showed good encapsulation parameters for both active ingredients and biological degradability by E. coli and faecal slurry. However, it will be necessary to use alginate derivatives to reduce its solubility and improve its mechanical behaviour.

Experimental therapy of epilepsy with transcranial magnetic stimulation: lack of additional benefit with prolonged treatment.

OBJECTIVE: To investigate the effect of three months of low-frequency repetitive transcranial magnetic stimulation (rTMS) treatment in intractable epilepsy. METHODS: Five patients (four males, one female; ages 6 to 50 years), were enrolled in the study; their epilepsy could not be controlled by medical treatment and surgery was not indicated. rTMS was performed twice a week for three months; patients kept records of seizure frequency for an equal period of time before, during, and after rTMS sessions. rTMS was delivered to the vertex with a round coil, at an intensity 5% below motor threshold. During rTMS sessions, 100 stimuli (five series of 20 stimuli, with one-minute intervals between series) were delivered at a frequency of 0.3 Hz. RESULTS: Mean daily number of seizures (MDNS) decreased in three patients and increased in two during rTMS--one of these was treated for only one month; the best result was achieved in a patient with focal cortical dysplasia (reduction of 43.09% in MDNS). In the whole patient group, there was a significant (p<0.01) decrease in MDNS of 22.8%. CONCLUSION: Although prolonged rTMS treatment is safe and moderately decreases MDNS in a group of patients with intractable epilepsy, individual patient responses were mostly subtle and clinical relevance of this method is probably low. Our data suggest, however, that patients with focal cortical lesions may indeed benefit from this novel treatment. Further studies should concentrate on that patient subgroup.

[Technical proofreading of nursing diagnosis books: perceptions of nurses from the south of Brazil]. / Revisão técnica de livros sobre diagnósticos de enfermagem: percepções de enfermeiras do sul do Brasil.

The present study is a report of an experience of nurses from the South of Brazil as technical proofreaders of books about nursing diagnosis. It aims at contributing with colleagues who might do similar task arousing some aspects for discussion. The development of nursing diagnosis in Brazil is presented. The main steps of a translated book production are identified and the attributions of technical proofreaders are cited. The positive aspects and the difficulties found in this activity are commented. Alternatives are given in order to maintain the final quality of the work and to enlarge the availability of specialized texts as faithful to the original as possible.

Release of prednisolone and inulin from a new calcium-alginate chitosan-coated matrix system for colonic delivery.

Putative colonic release formulations of calcium (Ca)-alginate coated with chitosan containing two different actives, prednisolone and inulin, were prepared in three different sizes, beads (D50 = 2104 µm) and microparticles (D50 = 354 and 136 µm). The formulations were tested in standard phosphate buffer and biorelevant Krebs bicarbonate buffer at pH 7.4, and were further evaluated in the presence of the bacterium E. coli. Product yield and encapsulation were higher with prednisolone than with inulin. In Krebs bicarbonate buffer, a clear relationship between particle size and prednisolone release was observed. In contrast, release of inulin was independent of the particle size. In phosphate buffer, the particles eroded quickly, whereas in Krebs buffer, the particles swelled slowly. The difference in behavior can be attributed to the formation of calcium phosphate in the phosphate buffer medium, which in turn weakens the Ca-alginate matrix core. In the presence of E. coli, the formulations were fermented and the release of prednisolone was accelerated. In conclusion, the buffer media affects formulation behavior and drug release, with the bicarbonate media providing a better simulation of in vivo behavior. Moreover, the susceptibility of the formulations to bacterial action indicates their suitability as carriers for colonic drug delivery.

Prevalence of alveolar bone loss in healthy children treated at private pediatric dentistry clinics.

OBJECTIVES: The purpose of this study was to evaluate the prevalence of alveolar bone loss (BL) in healthy children treated at private pediatric dentistry clinics in Brasília, Brazil. MATERIAL AND METHODS: The research included 7,436 sites present in 885 radiographs from 450 children. The BL prevalence was estimated by measuring the distance from the cementoenamel junction (CEJ) to alveolar bone crest (ABC). Data were divided in groups: (I) No BL: distance from CEJ to ABC is <2 mm; (II) questionable BL (QBL): distance from CEJ to ABC is >2 and <3 mm; (III) definite BL (DBL): distance from CEJ to ABC >3 mm. Data were treated by the chi-square nonparametric test and Fisher's exact test (p<0.05). RESULTS: Among males, 89.31% were classified in group I, 9.82% were classified in group II and 0.85% in group III. Among females, 93.05%, 6.48% and 0.46% patients were classified in Group I, II and III, respectively. The differences between genders were not statistically significant (Chi-square test, p = 0.375). Group composition according to patients' age showed that 91.11% of individuals were classified as group I, 8.22% in group II and 0.67% in group III. The differences among the age ranges were not statistically significant (Chi-square test, p = 0.418). The mesial and distal sites showed a higher prevalence of BL in the jaw, QBL (89.80%) and DBL (79.40%), and no significant difference was observed in the distribution of QBL (Fisher's exact test p = 0.311) and DBL (Fisher's exact test p = 0.672) in the dental arches. The distal sites exhibited higher prevalence of both QBL (77.56%) and DBL (58.82%). CONCLUSIONS: The periodontal status of children should never be underestimated because BL occurs even in healthy populations, although in a lower frequency.

Implicações da sexualidade e reprodução no adolescer saudável / Sexuality and reproduction: implications in the process of healthy adolescence

Este estudo objetivou compreender a percepção de adolescentes acerca de seu processo de adolescer saudável, no que se refere à sexualidade e reprodução. Trata de uma pesquisa qualitativa do tipo exploratória, realizada com 10 adolescentes, em uma escola estadual no sul do Rio Grande do Sul, entre agosto e outubro de 2007. Para a coleta dos dados, foram utilizadas entrevistas semiestruturadas, cujo conteúdo foi submetido à análise temática, surgindo o tema: Sexualidade e reprodução na adolescência. Diante dos dados, percebeu-se que é preciso proporcionar mais orientações para um adolescer saudável, no sentido de fortalecer e favorecer a segurança necessária ao adolescente no exercício da sua sexualidade e reprodução. Evidenciou-se também a necessidade de preparo do adolescente, seja por profissionais da saúde, da educação ou familiares, para o enfrentamento de algumas situações, tais como: gravidez indesejada, primeira relação sexual, automedicação, receio de conversar com os pais sobre sexualidade, dentre outras.

Experimental therapy of epilepsy with transcranial magnetic stimulation: lack of additional benefit with prolonged treatment

OBJETIVO: investigar o efeito de três meses de estimulação magnética transcraniana repetitiva (EMTr) de baixa freqüência, na epilepsia de difícil controle. MÉTODO: Cinco pacientes (quatro homens, uma mulher, idades entre 6 e 50 anos), participaram do estudo; suas crises epilépticas não puderam ser controlados por tratamento medicamentoso e não tinham indicação cirúrgica; a EMTr foi realizada duas vezes por semana durante três meses, sendo que os pacientes anotaram o número diário de crises neste período, assim como nos três meses anteriores e posteriores ao tratamento. A aplicação da EMTr foi feita no vértex com bobina circular, com intensidade 5 por cento abaixo do limiar motor. Durante as sessões de EMTr, 100 estímulos (5 séries de 20 estímulos, com um minuto de intervalo entre as séries) foram realizadas na freqüência de 0,3 Hz. RESULTADOS: A média diária de crises (MDC) decresceu em três pacientes e aumentou em dois durante o uso da EMTr; um destes casos foi tratado somente por um mês; o melhor resultado foi encontrado em um paciente com displasia cortical focal (redução de 43,09 por cento na MDC). Em todo o grupo de pacientes, houve decréscimo significativo na MDC de 22,8 por cento (p<0,01). CONCLUSAO: Embora o tratamento prolongado com a EMTr seja seguro e tenha sido registrado decréscimo moderado da MDC em um grupo de pacientes com epilepsia de difícil controle, respostas individuais de pacientes foram imprevisíveis e a relevância clínica deste método é provavelmente baixa. Nossos dados sugerem, contudo, que pacientes com lesões corticais focais podem ser beneficiar deste novo tipo de tratamento. Estudos futuros devem se concentrar neste grupo de pacientes.

Transmissão de bactérias periodontais: [revisão] / Transmission of periodontal bacteria: [review]

Periodontite corresponde a uma diversidade de doenças clinicamente diferentes, associadas com uma microbiota subgengival variável entre os diferentes grupos de pacientes. A maioria das espécies bacterianas subgengivais é indígena à cavidade bucal. Aggregatibacter actinomycetemcomitans e Porphyromonas gingivalis são considerados patógenos periodontais importantes que apresentam características de patógenos exógenos e não são frequentemente detectados em indivíduos com periodonto sadio. A transmissão de microrganismos entre pais e filhos (transmissão vertical) é particularmente evidente. Técnicas de genética molecular têm demonstrado que se uma criança é colonizada por uma espécie potencialmente patogênica, então um dos pais comumente abriga a bactéria idêntica genotipicamente. Os dados também indicam que transferência de bactéria entre cônjuges (transmissão horizontal) ocorre, embora não frequentemente. Todavia, a transferência de microrganismos não resulta necessariamente em colonização ou infecção do hospedeiro. Além disso, há indivíduos que abrigam periodonto patógenos e não manifestam qualquer sinal de doença periodontal. O propósito deste artigo é apresentar uma revisão da literatura sobre a transferência de bactérias associadas com as doenças periodontais entre membros da família.

Periodontitis corresponds to a variety of clinically different diseases associated with a variable subgingival microbiotaamong different patient groups. The majority of subgingival bacterial species are indigenous to the oral cavity.Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis are adjudged as important periodontais pathogen that presents characteristicsof exogenous pathogens and are infrequently detected in subjects with healthy periodontium. The transmission of microorganisms between parentsand children (ver tical transmission) is particularly evident. Molecular genetic techniques have demonstrated that if a child is colonized by a potentially pathogenic species, then one of the parents usually harbor genotypically identical bacteria. The data also indicate that transfer of bacteria between spouses (horizontal transmission) occurs, although infrequently. However, the transfer of microorganisms does not necessarily result in colonization or infection of the host. Furthermore, there are individuals who harbor periodontopathogens and do notmanifest any signs of periodontal disease. The purpose of this article is to present a review of the literature about the intra-familial transfer of bacteria associated with periodontal diseases.

Recobrimento radicular: retalho posicionado coronalmente x enxerto de tecido conjuntivo associado ao retalho posicionado coronalmente / Root coverage: coronally positioned flap x connective tissue graft associated with coronally positioned flap

O sucesso do tratamento das recessões gengivais baseia-se no conhecimento de sua etiologia e na avaliação da previsibilidade do recobrimento radicular. Diversas técnicas têm sido propostas para o tratamento das recessões gengivais. Entre estas, encontra-se o reposicionamento coronal do retalho com ou sem a colocação de enxerto subepitelial de tecido conjunti-vo. Ambas as modalidades têm grande aplicabilidade e são utilizadas freqüentemente pelo clínico. O trabalho propõe uma revisão da literatura sobre recobrimento radicular comparando as técnicas de reposicionamento coronal do retalho com ou sem a colocação de enxerto subepitelial de tecido conjuntivo, assunto este já bem explorado na literatura. Ainda assim, os autores conseguiram coletar referências importantes relacio-nadas ao tema.

Utilização do laser em bolsas periodontais revisão de literatura / Laser Utilization in Periodontal Pockets

O uso do laser tem sido avaliado tanto durante a raspagem e alisamento radicular, quanto como substituto de antimicrobianos sistêmicos na desinfecção de bolsas periodontais. Os estudos a respeito deste assunto são recentes, datando a partir da década de 90. Os lasers de baixa intensidade atuam como coadjuvantes à terapia periodontal. e trazem benefícios valiosos à mesma, como diminuição da hiperestesia dentinária e cura mais rápida dos teddos após raspagem. Quanto aos lasers de alta intensidade, é questionável sua eficácia no debridamento radicular sem que cause possíveis efeitos térmicos danosos à estrutura dentária. Este trabalho aborda a utilização do laser em bolsas periodontais e suas possíveis conseqüências
