Abstract In the quality control of herbal drugs, analysis of microscopy structures is crucial to detect any adulterants or substitutes. Microscopic analysis is considered one of the first pharmacopeial parameters of pharmacognostic identification. Cecropia pachystachya Trécul (Urticaceae), commonly known as “embaúba” or Ambay pumpwood, is a broadleaved tree species native to South America, from Brazil to Argentina. Cecropia pachystachya is used in traditional medicine as a diuretic, antiasthmatic, antidiabetic, anti-inflammatory, and anti-hypertensive. Due to the malpractice of adulterating botanicals with other species having similar morphology and therapeutic uses, an unrelated plant Tetrapanax papyrifer (Hook.) K. Koch (Araliaceae) is commonly used as an adulteration of C. pachystachya. Tetrapanax papyrifer was introduced into Brazil and utilized in folk medicine as an antidiarrheal, antitussive, anti-inflammatory, and expectorant. This work aimed to identify and differentiate between the two species using microscopic features of the leaf epidermis. The presence or absence and the morphotype of trichomes are sufficient to identify and differentiate between these species, in whole or pulverized form.

RESUMO O objetivo deste estudo transversal foi identificar adequações quanto à utilização de Equipamentos de Proteção Individual e organização do processo de trabalho no atendimento odontológico ambulatorial no Paraná durante o primeiro ano da pandemia da Covid-19. A amostra de conveniência incluiu 1.105 profissionais de saúde bucal (cirurgiões-dentistas, técnicos e auxiliares em saúde bucal) durante o primeiro ano da pandemia (agosto a outubro de 2020). Formulário on-line (Google Formulários®) foi enviado por e-mail pelo Conselho Regional de Odontologia. As medidas de enfrentamento da Covid-19 foram comparadas entre os tipos de serviços odontológicos: ambulatorial do Sistema Único de Saúde – SUS (Atenção Primária, Centro de Especialidades Odontológicos e Pronto Atendimento), clínica privada, e outros (Sistema S, forças de segurança, sindicatos, hospitais públicos e privados e clínicas de ensino). Os profissionais dos serviços ambulatoriais do SUS relataram com maior frequência que: suspenderam atendimentos eletivos, evitavam gerar aerossóis e trabalhavam a quatro mãos. Nas clínicas privadas, utilizavam frequentemente teleorientação e telemonitoramento. Nos ‘outros serviços’, houve maior proporção de redução das horas de trabalho e autoclavagem de peças de mão após cada atendimento. Conclui-se que, apesar da alta adequação às medidas de enfrentamento da Covid-19, houve diferença na prática profissional nos diferentes tipos de serviços odontológicos.

ABSTRACT This cross-sectional study aimed to identify adjustments regarding the use of Personal Protective Equipment and the organization of the work process in outpatient dental care in Paraná during the first year of the COVID-19 pandemic. The convenience sample included 1,105 oral health professionals (dental surgeons, oral health assistants, and dental hygienists) during the first year of the pandemic (August to October, 2020). An online form (Google Forms®) was sent by email by the Regional Council of Dentistry. COVID-19’s measures were compared between the types of dental services: ‘outpatient clinic of the Unified Health System – SUS’ (Primary Care, Dental Specialty Center, and Emergency Care), ‘private clinic’ and ‘other services’ (Sistema S, security forces, trade union, public and private hospitals, and teaching clinics). Professionals from SUS outpatient services reported more frequently: that they suspended elective care, avoided generating aerosols, and worked four-handed. Professionals from ‘private clinics’ used teleorientation and telemonitoring more regularly. In the ‘other services’, there was a more significant proportion reduction in work hours and handpieces autoclaving after each service. It is concluded that, despite the high adequacy of the measures to combat COVID-19, there was a difference in professional practice among the different types of dental services.

ABSTRACT The main goal of this study was to verify the association between serum and dietary concentrations of calcium, phosphorus and iron, and to determinate whether patients with kidney disease undergoing hemodialysis had inadequacy in dietary intake. We conducted a descriptive cross-sectional study that evaluated 40 patients undergoing hemodialysis. Food consumption was determined by the 24-hour recall. The optical technology method was used to obtain hemoglobin and hematocrit concentrations. Serum levels of iron, calcium and phosphorus were determined by dry chemistry. We observed insufficient consumption of energy, macronutrients and minerals. Energy intake of patients with longer hemodialysis was higher. The sample presented hypocalcemia, hyperphosphatemia (except in the group ≥8 years of hemodialysis), higher iron concentrations and lower hemoglobin and hematocrit values. The serum levels of minerals were not affected by dietary intake. There was a significant correlation between dietary phosphorus and calcium in patients undergoing hemodialysis for more than 8 years, those over 60 years old and, between calcium and phosphorus normal levels in patients over 60 years old. Hemoglobin, hematocrit and mineral serum levels were similar regardless of age and hemodialysis time. It was concluded that inadequacies of minerals reflected deregulation among metabolism and the pathophysiological changes inherent to Chronic Kidney Disease.

RESUMEN El objetivo principal de este estudio fue verificar la asociación entre las concentraciones séricas y dietéticas de calcio, fósforo y hierro, y determinar su ingesta dietética inadecuada en pacientes con enfermedad renal sometidos a hemodiálisis. Se trató de un estudio descriptivo transversal que evaluó a 40 pacientes en hemodiálisis. El consumo de alimentos se determinó mediante el recordatorio de 24 horas. Se utilizó el método de tecnología óptica para obtener concentraciones de hemoglobina y hematocrito. Los niveles séricos de hierro, calcio y fósforo se determinaron mediante química seca. El estudio mostró un consumo insuficiente de energía, macronutrientes y minerales. La ingesta energética de los pacientes con hemodiálisis más prolongada fue mayor. La muestra presentó hipocalcemia, hiperfosfatemia (excepto en el grupo ≥8 años de hemodiálisis), mayor concentración de hierro y menores valores de hemoglobina y hematocrito. Los niveles séricos de minerales no se vieron afectados por su ingesta dietética. Hubo una correlación significativa entre el fósforo dietético y el calcio en los pacientes en hemodiálisis durante más de 8 años y los mayores de 60 años y, también, entre los niveles normales de calcio y fósforo en los pacientes mayores de 60 años. Los niveles séricos de hemoglobina, hematocrito y minerales fueron similares independientemente de la edad y el tiempo de hemodiálisis. Se concluyó que las deficiencias de los minerales parecen reflejarse en la desregulación de su metabolismo y los cambios fisiopatológicos inherentes a la Enfermedad Renal Crónica.

Resumo Estudo quantitativo transversal descritivo que tem o objetivo de avaliar a percepção do graduando em medicina sobre a importância do ensino da ética médica e mensurar seu conhecimento sobre a temática em universidade pública do Nordeste brasileiro. Por meio de questionário aplicado a 230 estudantes foi possível avaliar deficiências provocadas pela ausência do ensino formal da ética médica e discutir a necessidade de abordagens diversificadas do tema durante a graduação. Resultados mostram maior taxa de acertos entre graduandos que cursaram ao menos uma disciplina sobre ética médica, mas índice insatisfatório em ambos os grupos. Um terço dos discentes que não tiveram contato com a temática revelaram não se sentir prejudicados por essa lacuna e 25,6% da amostra sequer valorizou a importância do tema em relação a outras disciplinas da graduação. Assim, torna-se necessário rever as estratégias do ensino médico para garantir melhores profissionais no futuro.

Abstract This descriptive cross–sectional study aimed to evaluate the medical student’s perception of the importance of medical ethics being taught and to measure their knowledge about the subject in a public university in the Northeast of Brazil. Through a questionnaire, applied to 230 undergraduates, it was possible to evaluate deficits caused by the absence of formal medical ethics education and to discuss the need for diversified approaches to the subject during graduation. Results show a higher rate of correct answers among undergraduates who attended at least one discipline on medical ethics; whereas they indicated an unsatisfactory rate of success in both groups. One third of the undergraduates who did not have contact with the subject revealed that they did not feel put at a disadvantaged by this gap, and 25.6% of the sample did not value the importance of the subject in comparison to other undergraduate subjects. Therefore, it is necessary to review medical education strategies to ensure better professionals in the future.
