ABSTRACT
Uremic pruritus is one of the skin complications that perplex patients with end-stage renal disease undergoing hemodialysis or peritoneal dialysis. Because the specific pathogenesis is not clear, there is no unified treatment plan in the world. In August 2021, the US Food and Drug Administration approved the use of difelikefalin (under the trade name Korsuva) for the treatment of moderate to severe pruritus associated with chronic kidney disease in adult patients undergoing hemodialysis. Studies have shown that difelikefalin can remarkably reduce the intensity of pruritus and improve sleep and pruritus-related quality of life. The recommended dose of difelikefalin is 0.5 μg/kg, and difelikefalin is well tolerated and has high safety. This paper reviews the pharmacological effects, pharmacokinetics, clinical efficacy and safety of difelikefalin.

ABSTRACT
SUMMARY OBJECTIVE: To review the main physiological and pharmacological changes related to prematurity, to promote the evidence-based clinical practice. METHODS: This is a narrative review whose research was carried out in the ScienceDirect and Medline databases via PubMed, searching for articles in any language from January 2000 to February 2020. RESULTS: Premature newborns are born before completing the maturation process that prepares them for extrauterine life, which occurs especially in the last weeks of pregnancy. Therefore, they have their own characteristics in development. Several physiological peculiarities stand out, such as disturbances in glucose regulation, adrenal function, thermoregulation, immunity, in addition to changes in liver, renal and respiratory functions. Pharmacological aspects were also highlighted, involving pharmacokinetics and pharmacodynamics. CONCLUSIONS: Despite the recent advances in prematurity, it is still an area with many uncertainties, since several changes occur quickly and there are ethical issues that make studies difficult. Thus, it is clear that the therapeutic management of premature infants is still very much based on clinical practice.

As a collective noun of incense and medicine, fragrant medicine has long been integrated into Chinese culture. It is not only a symbol of the cultural exchange between China and foreign countries in the middle ancient times, but also plays a very important role in medicine and other fields. Among them, Borneol can not only be used for medicinal purposes, but also for incense and fumigation, as well as food, tea, wine and other applications. This paper intends to sort out the medicinal properties, effects and other applications of Borneol recorded in ancient books of traditional Chinese herbs in the past dynasties, focusing on summarizing its medicinal properties, meridians, effects, compatibility and application characteristics. In addition, modern pharmacological action was included as a supplement, in order to provide reference for the clinical use of Borneol in medicinal aspects.
ABSTRACT
RESUMO Objetivo: Investigar a efetividade da vancomicina contra Gram-positivos com concentração inibitória mínima de 1mg/L em pacientes pediátricos com base na razão entre área sob a curva e concentração inibitória mínima > 400. Métodos: População de 22 pacientes pediátricos (13 meninos) internados no centro de terapia intensiva pediátrica, com função renal preservada, que foram distribuídos em dois grupos (G1 < 7 anos e G2 ≥ 7 anos). Após a quarta dose de vancomicina (10 - 15mg/kg a cada 6 horas), duas amostras de sangue foram colhidas (terceira e quinta horas), seguidas da dosagem sérica por imunoensaios para investigação da farmacocinética e da cobertura do antimicrobiano. Resultados: Não se registrou diferença entre os grupos com relação à dose, ao nível de vale ou ainda na área sob a curva. A cobertura contra Gram-positivos com concentração inibitória mínima de 1mg/L ocorreu em apenas 46% dos pacientes em ambos os grupos. A farmacocinética se mostrou alterada nos dois grupos diante dos valores de referência, mas a diferença entre grupos foi registrada pelo aumento da depuração total corporal e pelo encurtamento da meia-vida biológica, mais pronunciados nos pacientes mais novos. Conclusão: A dose empírica mínima de 60mg/kg ao dia deve ser prescrita ao paciente pediátrico de unidade de terapia intensiva com função renal preservada. A utilização da razão entre área sob a curva e concentração inibitória mínima na avaliação da cobertura da vancomicina é recomendada para se atingir o desfecho desejado, uma vez que a farmacocinética está alterada nesses pacientes, podendo impactar na efetividade do antimicrobiano.
Abstract Objective: To investigate the vancomycin effectiveness against gram-positive pathogens with the minimum inhibitory concentration of 1mg/L in pediatric patients based on the area under the curve and the minimum inhibitory concentration ratio > 400. Methods: A population of 22 pediatric patients (13 boys) admitted to the pediatric intensive care unit with preserved renal function was stratified in two groups (G1 < 7 years and G2 ≥ 7 years). After the fourth dose administered of vancomycin (10 - 15mg/kg every 6 hours) was administered, two blood samples were collected (third and fifth hours), followed by serum measurement by immunoassays to investigate the pharmacokinetics and antimicrobial coverage. Results: There was no difference between the groups regarding dose, trough level or area under the curve. Coverage against gram-positive pathogens with a minimum inhibitory concentration of 1mg/L occurred in only 46% of patients in both groups. The pharmacokinetics in both groups were altered relative to the reference values, and the groups differed in regard to increased total body clearance and shortening of the biological half-life, which were more pronounced in younger patients. Conclusion: A minimum empirical dose of 60mg/kg per day should be prescribed for pediatric patients in intensive care units with preserved renal function. The use of the ratio between the area under the curve and minimum inhibitory concentration in the evaluation of vancomycin coverage is recommended to achieve the desired outcome, since the pharmacokinetics are altered in these patients, which may impact the effectiveness of the antimicrobial.

ABSTRACT
Analisar as evidências científicas relacionadas ao tempo de administração endovenosa do Meropenem na prática clínica. Trata-se de uma revisão integrativa de literatura, retrospectiva, de natureza descritiva, com abordagem quantitativa com destaque para a produção científica de estudos clínicos randomizados, revisão sistemática e meta-análise. As bases de dados utilizadas foram Cochrane e Pubmed. A seleção da amostra foi realizada por dois pesquisadores independentes, utilizou-se instrumento adaptado para verificar o nível de evidência, grau de recomendação e classificação pela escala de Jadad. Foram selecionados 12 artigos referentes à administração endovenosa de forma contínua e intermitente do Meropenem. Dos quais nove eram ensaio clínico randomizado, dois eram ensaio clínico randomizado controlado e um meta-análise, destes 11 apresentavam nível II de evidência científica. A maioria dos estudos comparou a infusão rápida, em 30 minutos e/ou 3 horas, seguidos de estudos com administração rápida e/ou 30 minutos em infusão contínua. Os resultados dos estudos apontam que na infusão intermitente, com tempo de administração rápida, o pico da concentração plasmática não é suficiente para garantir eficácia do Meropenem. Já, para os estudos que abordaram a infusão intermitente clássica com tempo ≥ 3 horas demonstram que a técnica mantém melhor concentração inibitória mínima, devido à infusão ser prolongada.
This study aims to analyze the scientific evidence regarding the intravenous administration time of Meropenem in clinical practice. This is an integrative, retrospective, descriptive literature review, with a quantitative approach and emphasis on the scientific work of randomized clinical trials, with systematic review and meta-analysis. The databases used were Cochrane and PubMed. The samples were selected by two independent researchers, and an adapted instrument was used to verify the evidence level, recommendation grade and classification against the Jadad scale. A total of 12 articles related to the intravenous administration of continuous and intermittent Meropenem were selected. Nine of which were randomized studies, two were randomized controlled trials and one was a meta-analysis. From the total studies, 11 presented level II scientific evidence. Most studies compared rapid infusion, 30 minutes and/or 3 hour infusions, followed by rapid administration and/or 30 minute studies in continuous infusion. The results of the studies show that intermittent infusion with rapid time management presented peak plasma concentration that is not sufficient to guarantee the effectiveness of Meropenem. However, studies that addressed the classic intermittent infusion time ≥ 3 hours showed that the technology provides a better minimum inhibitory concentration due to the extended infusion time.

ABSTRACT
Os objetivos principais do tratamento da tuberculose são curar o paciente e minimizar a possibilidade de transmissão do bacilo para indivíduos saudáveis. Reações adversas ou interações das drogas antituberculose entre si e com outros fármacos podem causar modificação ou descontinuação da terapêutica. Revisamos sucintamente o novo tratamento farmacológico da tuberculose introduzido pelo Ministério da Saúde do Brasil em 2009 e mostramos os mecanismos gerais de ação, absorção, metabolização e excreção dos medicamentos utilizados no esquema básico. Descrevemos as reações adversas e as interações (com medicamentos, alimentos e antiácidos) assim como a abordagem mais adequada para situações especiais, como gravidez, amamentação, insuficiência hepática e renal. Também descrevemos os mecanismos pelos quais as interações das drogas antituberculose do esquema básico podem causar hepatite medicamentosa e as possíveis alternativas nessa situação.
The main objectives of tuberculosis therapy are to cure the patients and to minimize the possibility of transmission of the bacillus to healthy subjects. Adverse effects of antituberculosis drugs or drug interactions (among antituberculosis drugs or between antituberculosis drugs and other drugs) can make it necessary to modify or discontinue treatment. We briefly review the new guidelines for the pharmacological treatment of tuberculosis, introduced by the Brazilian National Ministry of Health in 2009, and describe the general mechanism of action, absorption, metabolization, and excretion of the first-line drugs used in the basic regimen. We describe adverse drug reactions and interactions (with other drugs, food, and antacids), as well as the most appropriate approach to special situations, such as pregnancy, breastfeeding, liver failure, and kidney failure. We also describe the mechanisms by which the interactions among the antituberculosis drugs used in the basic regimen can cause druginduced hepatitis, and we discuss the alternatives in this situation.
