Availability of emergency contraception in large Brazilian municipalities: a guaranteed right?

Introduction: Emergency Contraception (EC) is available in Brazil since 1996, when it was adopted as one if the family planning strategies and, in 1998, for use in services assisting victims of sexual violence. In the country, its use is regulated by guidelines. Its access through SUS (Unified Health System), however, does not seem to occur in a standardized manner. Methods: The aim of the study was to analyze the availability and barriers to accessing emergency contraception (levonorgestrel) in Brazilian municipalities with more than 500 thousand inhabitants. The survey was carried out by a form sent to the Municipal Health Departments (SMS) managers and a search on the list of standardized medicines by the hospitals in the same municipalities. Results: The Basic Health Units were identified as the standard access places to EC. However, one of the obstacles mentioned is the need for a prescription for dispensing in almost 80% of the analyzed cities. Access in emergency situations at night and on weekends is also uncertain, since although 67% of the places stated that they dispense at the hospital level, the item was only standardized in 21% of the hospital lists. Discussion: The difficult access this drug in the public system essentially tends to harm the poorest women, who are the ones who suffer most from the consequences of an unwanted pregnancy.

Development and characterization of a temozolomide-loaded nanoemulsion and the effect of ferrocene pre and co-treatments in glioblastoma cell models.

BACKGROUND: Glioblastoma is a severe brain tumor that requires aggressive treatment involving surgery, radiotherapy, and chemotherapy, offering a survival rate of only 15 months. Fortunately, recent nanotechnology progress has enabled novel approaches and, alongside ferrocenes' unique properties of cytotoxicity, sensitization, and interaction with reactive oxygen species, have brought new possibilities to complement chemotherapy in nanocarrier systems, enhancing treatment results. METHODS: In this work, we developed and characterized a temozolomide-loaded nanoemulsion and evaluated its cytotoxic potential in combination with ferrocene in the temozolomide-resistant T98G and temozolomide-sensitive U87 cell lines. The effects of the treatments were assessed through acute assays of cell viability, cell death, mitochondrial alterations, and a treatment protocol simulation based on different two-cycle regimens. RESULTS: Temozolomide nanoemulsion showed a z-average diameter of 173.37 ± 0.86 nm and a zeta potential of - 6.53 ± 1.13 mV. Physicochemical characterization revealed that temozolomide is probably associated with nanoemulsion droplets instead of being entrapped within the nanostructure, allowing a rapid drug release. In combination with ferrocene, temozolomide nanoemulsion reduced glioblastoma cell viability in both acute and two-cycle regimen assays. The combined treatment approach also reversed T98G's temozolomide-resistant profile by altering the mitochondrial membrane potential of the cells, thus increasing reactive oxygen species generation, and ultimately inducing cell death. CONCLUSIONS: Altogether, our results indicate that using nanoemulsion containing temozolomide in combination with ferrocene is an effective approach to improve glioblastoma therapy outcomes.

Avaliação de medicamentos potencialmente inapropriados e da polifarmácia em pacientes idosos em um hospital universitário / Evaluation of potentially inappropriate medications and polypharmacy in elderly patients at a university hospital

Introdução: O Brasil, assim como outros países, vem alterando seu perfil demográfico elevando o número de pessoas idosas, o que repercute em mudanças não só para sociedade, mas também para saúde pública. Este grupo de pacientes é mais vulnerável devido à fisiologia inerente ao envelhecimento, logo se tornam mais propensos ao uso de medicamentos que podem causar outros problemas de saúde. Essa probabilidade de risco é uma preocupação atual e levou a criação de métodos que norteiam os prescritores para adequarem suas terapêuticas neste grupo de pacientes. Um destes métodos é o critério de Beers, que é atualizado periodicamente trazendo uma lista de medicamentos potencialmente inapropriados (MPIs) para idosos. Objetivo: Avaliar a prescrição de pacientes idosos internados no Hospital Universitário da Universidade Federal de Juiz de Fora (HU-UFJF/Ebserh) quanto à prevalência do uso de MPI e polifarmácia, no período de julho a agosto de 2019. Material e Métodos: Estudo observacional descritivo e retrospectivo, cujos dados foram coletados de prontuários pacientes idosos com idade igual ou superior a 65 anos para obtenção dos resultados que foram avaliados estatisticamente. Resultados: Foram avaliados 187 prontuários, e observada prevalência de 80,2% da prescrição de MPIs, sendo os mais prevalentes omeprazol e benzodiazepínicos. A maioria dos pacientes tiveram polifarmácia (95,7%). Conclusão: Os resultados convergem com base no critério de Beers, para necessidade de adequar a terapia de pacientes idosos. É necessário também avaliar os benefícios e alternativas quanto aos MPIs mais prevalentes, além de realizar estudos observacionais sobre possíveis efeitos adversos que possam ser consequência do uso desses medicamentos, com objetivo de aperfeiçoar a terapia farmacológica e aprimorar a farmacoeconomia, melhorando assim a qualidade de vida dos pacientes idosos.

Introduction: Brazil, like other countries, has been changing its demographic profile, increasing the number of elderly people, which reflects in changes not only for society, but also for public health. This group of patients is more vulnerable due to the inherent physiology of aging, so they become more likely to use medications that can cause other health problems. This risk probability is a current concern and has led to the creation of methods that guide prescribers to adapt their therapies in this group of patients. One of these methods is the Beers criterion, which is periodically updated with a list of potentially inappropriate medications (PIM) for the elderly. Objective: To evaluate the prescription of elderly patients hospitalized at the University Hospital of Juiz de Fora (HU-UFJF/Ebserh) regarding the prevalence of the use of PIM and polypharmacy, from July to August 2019. Material and Methods: Descriptive and retrospective observational study, whose data were collected from medical records of elderly patients aged 65 years or older to obtain the results that were statistically evaluated. Results: A total of 187 medical records were evaluated, and a prevalence of 80.2% of the prescription of PIMs was observed, the most prevalent being omeprazol and benzodiazepines. Most patients had polypharmacy (95.7%). Conclusion: The results converge, based on the Beers criterion, for the need to suit the therapy of elderly patients. It is also necessary to evaluate the benefits and alternatives regarding the most prevalent PIMs, in addition to conducting observational studies on possible adverse effects that may be a consequence of the use of these medications, aiming to refine pharmacological therapy and improve pharmacoeconomics, thus improving quality of life of elderly patients.

Is there a fair distribution of the structure of dental services in the capitals of the Brazilian Federative Units?

BACKGROUND: Brazilian Primary Care Facilities (PCF) provide primary care and must offer dental services for diagnosis, prevention, and treatment of diseases. According to a logic of promoting equity, PCF should be better structured in less developed places and with higher need for oral health services. OBJECTIVE: To analyze the structure of dental caries services in the capitals of the Brazilian Federative Units and identify whether socioeconomic factors and caries (need) are predictors of the oral health services structure. METHODS: This is an ecological study with variables retrieved from different secondary databases, clustered for the level of the federative capitals. Descriptive thematic maps were prepared, and structural equations were analyzed to identify oral health service structure's predictors (Alpha = 5%). Four models with different outcomes related to dental caries treatment were tested: 1) % of PCF with a fully equipped office; 2) % of PCF with sufficient instruments, and 3) % of PCF with sufficient supplies; 4) % of PCF with total structure. RESULTS: 21.6% of the PCF of the Brazilian capitals had a fully equipped office; 46.9% had sufficient instruments, and 30.0% had sufficient supplies for caries prevention and treatment. The four models evidenced proper fit indexes. A correlation between socioeconomic factors and the structure of oral health services was only noted in model 3. The worse the socioeconomic conditions, the lower the availability of dental supplies (standard factor loading: 0.92, P = 0.012). Estimates of total, direct and indirect effects showed that dental caries experience observed in the Brazilian population by SB-Brasil in 2010 did not affect the outcomes investigated. CONCLUSION: Material resources are not equitably distributed according to the socioeconomic conditions and oral health needs of the population of the Brazilian capitals, thus contributing to persistent oral health inequities in the country.

Dentists' knowledge regarding signs and symptoms of the systemic toxicity of local anesthetic solutions / Conhecimento de cirurgiões-dentistas sobre sinais e sintomas de toxicidade sistêmica associados ao uso de soluções anestésicas locais

OBJECTIVE: To evaluate the knowledge of dentists about signs and symptoms that may be indicative of systemic toxicity associated with the use of local anesthetic solutions. METHODS: One hundred and twenty-four (124) dentists from private clinics in São Luís (Maranhão, Brazil) answered a questionnaire regarding the choice of solutions, selection criteria for local anesthetics and vasoconstrictors, and side effects associated with these substances. Results were analyzed by using descriptive statistics. RESULTS: Although most respondents reported being likely to choose local anesthetics at less toxic concentrations (including 2% mepivacaine or lidocaine), they were also likely to have similar vasoconstrictor solutions (epinephrine) as the second choice. The main selection criteria of anesthetic solutions reported were the duration of procedures and patients' individual characteristics. In general, dentists demonstrated being aware of some side effects associated with vasoconstrictors; however, they showed a lack of knowledge regarding signs and symptoms related to an overdose of local anesthetics. CONCLUSION: The group of dentists involved in this study showed limited knowledge about the toxicity of local anesthetics, as well as some inconsistent background over the choice of vasoconstrictors. Thus, strategies are required towards improving the knowledge of professionals from private dental clinics regarding local anesthetics and/or vasoconstrictors. .

OBJETIVO: Avaliar as soluções anestésicas utilizadas por um grupo de cirurgiões-dentistas e o nível de conhecimento desses profissionais sobre riscos associados a essas substâncias. MÉTODOS: Cento e vinte e quatro (124) cirurgiões-dentistas da rede privada do município de São Luís (Maranhão, Brasil) responderam um questionário contendo perguntas relativas às soluções de escolha, aos critérios de escolha de anestésicos locais e vasoconstritores e à avaliação do conhecimento sobre os efeitos colaterais associados às substâncias. RESULTADOS: Os resultados obtidos foram analisados utilizando-se estatística descritiva. Observou-se que a maior parte dos cirurgiões-dentistas optaram por anestésicos locais em concentrações menos tóxicas, como a mepivacaína 2% e a lidocaína 2%, porém se verificou que a maioria dos profissionais optaram pelo mesmo vasoconstritor (epinefrina) em soluções de segunda escolha. Os principais critérios de escolha das soluções anestésicas foram a duração do procedimento e as características do paciente. Analisando os dados em conjunto, os cirurgiões-dentistas pareceram conhecer alguns efeitos colaterais associados a vasoconstritores, porém demonstraram uma deficiência no conhecimento de sinais e sintomas relacionados à sobredosagem de anestésicos locais. CONCLUSÃO: Concluiu-se que o grupo de cirurgiões-dentistas envolvido no presente estudo apresentou conhecimento limitado em relação à toxicidade de anestésicos locais, bem como contradição em relação à escolha de vasoconstritores. Estratégias para aprofundar o conhecimento sobre anestésicos locais e/ou vasoconstritores de profissionais da rede privada são necessárias. .
