RESUMO

Fungal infections cause 1.7 million deaths annually, which can be attributed not only to fungus-specific factors, such as antifungal resistance and biofilm formation, but also to drug-related challenges. In this study, the potential of Amphotericin (AmB) loaded polymeric nanoparticles (AmB-NPs) combined with murine monoclonal antibodies (mAbs) (i.e., CC5 and DD11) was investigated as a strategy to overcome these challenges. To achieve this goal, AmB-NPs were prepared by nanoprecipitation using different polymers (polycaprolactone (PCL) and poly(D,L-lactide) (PLA)), followed by comprehensive characterization of their physicochemical properties and in vitro biological performance. The results revealed that AmB-loaded NPs exhibited no cytotoxicity toward mammalian cells (baby hamster kidney cells-BHK and human monocyte cells-THP-1). Conversely, both AmB-NPs demonstrated a cytotoxic effect against C. albicans, C. neoformans, and H. capsulatum throughout the entire evaluated range (from 10 µg/mL to 0.1 µg/mL), with a significant MIC of up to 0.031 µg/mL. Moreover, the combination of AmB-NPs with mAbs markedly intensified antifungal activity, resulting in a synergistic effect that was two to four times greater than that of AmB-NPs alone. These findings suggest that the combination of AmB-NPs with mAbs could be a promising new treatment for fungal infections that is potentially more effective and less toxic than current antifungal treatments.

RESUMO

OBJECTIVE: To evaluate the effectiveness of vaccines developed against covid-19 in reducing mortality in people hospitalized with severe acute respiratory syndrome (SARS) caused by SARS-CoV-2. METHODS: This is a retrospective cohort that evaluated risk factors and the effectiveness of the two-dose vaccination schedule in reducing the mortality of people hospitalized for covid-19 in the state of Paraíba from February to November 2021. The explanatory variables were vaccination status, presence of comorbidities, socioeconomic and demographic characteristics. Descriptive analyses and bivariate and multivariable logistic regression were performed. RESULTS: Most hospitalizations and deaths occurred until May 2021. The percentage of patients with a complete vaccination schedule was similar across patients admitted to public and private hospitals and higher in residents of less developed municipalities. Multivariable analysis demonstrated that women (OR = 0.896; 95%CI 0.830-0.967) and people admitted to private hospitals (OR = 0.756; 95%CI 0.679-0.842) were less likely to die. Presence of any comorbidity (OR = 1.627; 95%CI 1.500-1.765) and age ≥ 80 years (OR = 7.426; 95%CI 6.309-8.741) were risk factors for death. Patients with complete vaccination schedule at the time of admission were 41.7% less likely to die (OR = 0.583; 95% CI 0.501-0.679) from covid-19 in the adjusted analysis, as compared to unvaccinated patients. CONCLUSIONS: The study reveals that immunization was effective in reducing the likelihood of death from covid-19. The results suggest that greater vaccination coverage in the first half of 2021 would prevent thousands of deaths in the country.

RESUMO OBJETIVO Avaliar a efetividade das vacinas desenvolvidas contra a covid-19 na redução da mortalidade em pessoas internadas com síndrome respiratória aguda grave (SRAG) causada pelo SARS-CoV-2. MÉTODOS Trata-se de uma coorte retrospectiva que avaliou fatores de riscos e a efetividade do esquema vacinal com duas doses na redução da mortalidade de pessoas internadas por covid-19 no estado da Paraíba entre fevereiro e novembro de 2021. As variáveis explicativas foram situação vacinal, presença de comorbidades, características socioeconômicas e demográficas. Foram realizadas análises descritivas e regressão logística bivariada e multivariável. RESULTADOS A maior parte das internações e óbitos ocorreram até maio de 2021. O percentual de pacientes com esquema vacinal completo foi similar entre pacientes internados em hospitais públicos e privados e superior em residentes de municípios com menor desenvolvimento. A análise multivariável demonstrou que mulheres (OR = 0,896; IC95% 0,830-0,967) e pessoas internadas em hospitais privados (OR = 0,756; IC95% 0,679-0,842) apresentaram menor chance de morte. A presença de alguma comorbidade (OR = 1,627; IC95% 1,500-1,765) e idade ≥ 80 anos (OR = 7,426; IC95% 6,309-8,741) foram fatores de risco de óbito. Pacientes com esquema vacinal completo no momento da internação apresentaram uma chance 41,7% menor de morte (OR = 0,583; IC95% 0,501-0,679) por covid-19 na análise ajustada, quando comparados com pacientes não vacinados. CONCLUSÕES O estudo revela que a imunização foi efetiva na redução da chance de óbito por covid-19. Os resultados sugerem que uma maior cobertura vacinal no primeiro semestre de 2021 evitaria milhares de mortes no país.

RESUMO

Resumo Introdução: O conhecimento das habilidades de comunicação clínica é primordial para o adequado exercício da medicina de família e comunidade (MFC), visto que um dos princípios da especialidade advém da relação médico-pessoa. A comunicação assertiva é uma competência clínica básica que deve ser aprendida, sobretudo, durante a residência médica. Não se trata de uma característica inata, perpassa um processo de conhecer, aplicar e dominar, necessitando, portanto, de avaliações. Objetivo: Este estudo teve como objetivo avaliar a percepção dos médicos residentes de MFC em relação às suas habilidades de comunicação. Método: Trata-se de um estudo quantitativo, descritivo e transversal. O cenário de estudo foi o conjunto de programas de residência de MFC do município de João Pessoa, na Paraíba. A coleta de dados foi feita a partir de um questionário on-line, disponível para preenchimento de setembro a novembro de 2022. Utilizamos para a construção do questionário o instrumento A Consulta em 7 Passos. Desenvolvemos escores denominados índice de desempenho geral (IDg), índice de desempenho por passo da consulta (IDp) e índice de desempenho por item (IDitem). Na análise estatística, utilizamos o teste t para amostras independentes. Resultado: O IDg médio foi de 72,0%. Os residentes tiveram o maior índice de IDp no passo 5 da consulta (81,7%), seguido pelos passos 2 (77,6%), 3 (76,1%) e 6 (75,9%). Os menores desempenhos foram nos passos 4 (68,9%), 7 (63,7%) e 1 (63,3%). Não houve significância estatística quanto ao desempenho quando se compararam sexo, ano de residência e programa. Conclusão: Os residentes de MFC avaliam positivamente suas habilidades de comunicação. Entretanto, ainda há o que aprimorar, como fomentar momentos crítico-reflexivos sobre os fenômenos subjetivos que ocorrem na consulta. Destarte, a utilização do instrumento A Consulta em 7 Passos se revelou, no presente estudo, como uma ferramenta importante no processo de formação e avaliação da comunicação clínica durante a residência.


Abstract Introduction: Knowledge of clinical communication skills is essential for the proper practice of Family Medicine, since one of the principles of the specialty treats the doctor-person relationship as fundamental. Good communication is a basic clinical competence and must be learned, above all, during medical residency. Communication is not an innate characteristic, but a process of self-knowledge, therefore requiring self-assessments. Objective: This study aimed to evaluate the perception of Family Medicine residents doctors in relation to their communication skills. Method: This is a quantitative, descriptive and cross-sectional study. The study setting was the set of Family Medicine Residency Programs in the city of João Pessoa, Paraíba. Data collection was performed using an online questionnaire, available to be completed from September to November 2022. We used the instrument A consulta em 7 passos (7-step consultation) to construct the questionnaire. We developed scores called overall performance index (IDg), query step performance index (IDp) and item performance index (IDitem). In the statistical analysis, we used the t test for independent samples. Result: The average overall performance index (IDg) was 72.0%. Residents had the highest IDp rate in step 5 of the consultation (81.7%), followed by step 2 (77.6%), step 3 (76.1%) and step 6 (75.9% ). While residents had the lowest performances in descending order in steps 4 (68.9%), 7 (63.7%) and 1 (63.3%). There was no statistical significance between sexes, year of residency and residency program. Conclusion: MFC residents positively evaluate their communication skills. However, there is still room forto improvement in how to encourage critical-reflective moments about the subjective phenomena that occur in the consultation. Furthermore, the use of a consulta em 7 passos is an important tool in the training and evaluation process in residency.

RESUMO

The shortage of physicians in rural and underserved areas is an obstacle to the implementation of Universal Health Coverage (UHC). We carried out a systematic review to analyze the effectiveness of initiatives in medical education aimed to increase the supply of physicians in rural or underserved areas. We searched for studies published between 1999 and 2019 in six databases, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Interventional or observational controlled studies were defined as inclusion criteria. A total of 955 relevant unique records were selected for inclusion, which resulted in the identification of 17 articles for analysis. The admission of students from rural areas associated with a rural curriculum represented 52.95% of the interventions. Medical practice after graduation in rural or underserved areas was the most evaluated outcome, representing 12 publications (70.59%). Participants of these educational initiatives were more likely to work in rural or underserved areas or to choose family medicine, with significant differences between the groups in 82.35% of the studies. Educational strategies in undergraduate and medical residencies are effective. However, it is necessary to expand these interventions to ensure the supply of physicians in rural or urban underserved areas.

RESUMO

INTRODUCTION: Various initiatives to improve access to health care have been implemented internationally. In Brazil, this has included policies intended to expand access to higher education for underrepresented socio-economic groups. These measures have reduced inequalities in access to medical education, but it is not known whether they influence career choices. We examine the effect of these educational policies on physician practice patterns in primary care and/or in medically underserved areas. METHODS: This is a cross-sectional study that analysed the association between affirmative educational policies and the career choices of physicians who graduated between 2010 and 2015. Multivariate binary regression analysis was used to evaluate the impact of affirmative educational policies on physician career choices, including primary care practice, practice in cities with ≤20 000 inhabitants, and practice in less developed municipalities 4 years after graduation. RESULTS: We identified the practice patterns of 65 304 (82.8%) physicians 4 years after their graduation. Most physicians included in our analysis were female (54.5%), aged ≤27 years (72.4%), born in developed cities and studied in private medical schools. Physicians admitted to medical school based on racial or social access policies were more likely to practice in municipalities with fewer than 20 000 inhabitants (odds ratio [OR]: 1.64; 1.36-1.98) and in primary care (OR: 1.55; 1.35-1.53). Physicians who benefited from scholarships for under-represented socio-economic groups were more likely to practice in small cities (OR: 1.24; 1.07-1.43) and primary care (OR: 1.23; 1.11-1.37). The provision of financial aid also improved the likelihood of practice in primary care and underserved areas. Graduation from medical schools located in smaller cities was associated with practice in municipalities ≤20 000 inhabitants and primary care. CONCLUSIONS: Our results demonstrated that educational policies implemented in the Brazilian context are effective in reducing inequities in physician distribution and led to an increase in the number of physicians practicing in primary care.

RESUMO

Resumo Este estudo avalia o impacto de políticas de ampliação do acesso ao ensino superior na redução de iniquidades no perfil dos egressos de cursos médicos no Brasil. Estudo transversal que utiliza dados do Censo da Educação Superior de 2018. Foram realizadas análises para identificar associação entre ser beneficiário da Lei de Cotas, do Programa Universidade para Todos ou do Fundo de Financiamento Estudantil e três marcadores: nascimento em município de pequeno porte, ser não-branco ou ter cursado ensino médio em escola pública. Realizamos análises utilizando teste de qui-quadrado de Pearson e análise multivariada através de regressão de Poisson. Houve associação significativa entre ser beneficiário destas políticas e ser egresso não branco, ter nascido em município de pequeno porte e ser egresso de escola pública no ensino médio. Todas as políticas apresentaram resultados de Razões de Prevalências (RP) ajustadas superiores a um e com significância estatística. A Lei de Cotas foi a política mais efetiva com RP=1,92 para ser egresso não-branco, RP=6,66 para ter estudado ensino médio em escola pública e RP=1,08 para ter nascido em município de pequeno porte. Apesar destes resultados, estes grupos continuam sub-representados nos cursos médicos e na composição da força de trabalho.


Abstract This study assesses the effectiveness of policies to expand access to higher education in reducing inequities in the profile of graduates from medical courses in Brazil. This work consists of a cross-sectional study using data from the 2018 Higher Education Census. Analyses were carried out to identify the association between being a beneficiary of the Quota Law, the University for All Program, or the Student Financing Fund and three markers: born in a small-sized municipality, being non-white, or having attended high school in a public school. Analyses were performed using Pearson's chi-square test, and multivariate analysis was conducted using Poisson regression. A significant association was found between being a beneficiary of these policies and being a non-white graduate, who was born in a small town and who had studied in a public high school. All policies presented adjusted Prevalence Ratio (PR), which demonstrated an association with statistical significance. The Quota Law was the most effective policy, with RP=1.92 for non-white graduates, RP=6.66 for having studied in a public high school, and RP=1.08 for being born in a small town. Despite these results, these groups remain underrepresented in medical courses and in the workforce.
