Racial Differences in Blood Pressure Control from Users of Antihypertensive Monotherapy: Results from the ELSA-Brasil Study. / Diferenças Raciais no Controle da Pressão Arterial em Usuários de Anti-Hipertensivos em Monoterapia: Resultados do Estudo ELSA-Brasil.

BACKGROUND: It seems that the worst response to some classes of antihypertensive drugs, especially angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, on the part of the Black population, would at least partially explain the worse control of hypertension among these individuals. However, most of the evidence comes from American studies. OBJECTIVES: This study aims to investigate the association between self-reported race/skin color and BP control in participants of the Longitudinal Study of Adult Health (ELSA-Brasil), using different classes of antihypertensive drugs in monotherapy. METHODS: The study involved a cross-sectional analysis, carried out with participants from the baseline of ELSA-Brasil. Blood pressure control was the response variable, participants with BP values ≥140/90 mmHg were considered out of control in relation to blood pressure levels. Race/skin color was self-reported (White, Brown, Black). All participants were asked about the continuous use of medication. Association between BP control and race/skin color was estimated through logistic regression. The level of significance adopted in this study was of 5%. RESULTS: Of the total of 1,795 users of antihypertensive drugs in monotherapy at baseline, 55.5% declared themselves White, 27.9% Brown, and 16.7% Black. Even after adjusting for confounding variables, Blacks using angiotensin converting enzyme inhibitors (ACEI), angiotensin receptor blocker (ARB), thiazide diuretics (thiazide DIU), and beta-blockers (BB) in monotherapy had worse blood pressure control compared to Whites. CONCLUSIONS: Our results suggest that in this sample of Brazilian adults using antihypertensive drugs in monotherapy, the differences in blood pressure control between different racial groups are not explained by the possible lower effectiveness of ACEIs and ARBs in Black individuals.

FUNDAMENTO: Aparentemente, a pior resposta a algumas classes de anti-hipertensivos, especialmente inibidores da enzima conversora da angiotensina e bloqueadores de receptor de angiotensina, pela população negra, explicaria, pelo menos parcialmente, o pior controle da hipertensão entre esses indivíduos. Entretanto, a maioria das evidências vêm de estudos norte-americanos. OBJETIVOS: Este estudo tem o objetivo de investigar a associação entre raça/cor da pele autorrelatadas e controle de PA em participantes do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) utilizando várias classes de anti-hipertensivos em monoterapia. MÉTODOS: O estudo envolveu uma análise transversal, realizada com participantes da linha de base do ELSA-Brasil. O controle de pressão arterial foi a variável de resposta, participantes com valores de PA ≥140/90 mmHg foram considerados descontrolados em relação aos níveis de pressão arterial. A raça/cor da pele foi autorrelatada (branco, pardo, negro). Todos os participantes tiveram que responder perguntas sobre uso contínuo de medicamentos. A associação entre o controle de PA e raça/cor da pele foi estimada por regressão logística. O nível de significância adotado nesse estudo foi de 5%. RESULTADOS: Do total de 1.795 usuários de anti-hipertensivos em monoterapia na linha de base, 55,5% se declararam brancos, 27,9%, pardos e 16,7%, negros. Mesmo depois de padronizar em relação a variáveis de confusão, negros em uso de inibidores da enzima conversora de angiotensina (IECA), bloqueadores de receptor de angiotensina (BRA), diuréticos tiazídicos (DIU tiazídicos) e betabloqueadores (BB) in monoterapia tinham controle de pressão arterial pior em comparação a brancos. CONCLUSÕES: Os resultados deste estudo sugerem que, nesta amostra de brasileiros adultos utilizando anti-hipertensivos em monoterapia, as diferenças de controle de pressão arterial entre os vários grupos raciais não são explicadas pela possível eficácia mais baixa dos IECA e BRA em indivíduos negros.

Mobile Applications (Apps) to Support the Hepatitis C Treatment: A Systematic Search in App Stores.

The purpose of this review was to identify apps to support the HCV treatment and perform a quality assessment. A comprehensive search was conducted until February 2020 in Apple App Store (iOs) and Google Play Store (Android) using search term such "hepatitis", "hepatology", and "HCV". Two independent authors identified the apps and performed data extraction and quality assessment using Mobile App Rating Scale (MARS). Spearman's correlation analysis was used to analyze the relationships between user's star ratings found in the app stores and quality app defined by the MARS instrument. A total of 316 potential apps were identified, of which 12 apps fully met the eligibility criteria. Most apps were available in both App Stores and developed by commercial developers for healthcare provider. Almost all of apps were updated within the last two year and received 3.7 or above star ratings from users. Overall, only one app was considered with a good quality. The average scores for objective and subjective MARS quality of these apps were 3.54 (SD = 0.65) and 3.27 (SD = 0.76), respectively. Moreover, a majority of apps received objective scores between 3.29 and 4.37/5. However, MARS items such "interactivity", "visual appeal", "quality information", and "credibility" obtained minimum acceptable scores. MARS scores were not significantly correlation the user's star ratings. This systematic search found gaps in apps to support the HCV treatment; 12 apps were identified in this study and only one app achieved a good quality. There is a need that users use these apps cautiously as well as involve expert healthcare professionals in the development of new HCV apps.

Irrational use of alendronate sodium by the elderly / Uso irracional de alendronato de sódio por idosos / Uso irracional de alendronato de sodio en los ancianos

Introduction: The effectiveness and safety of alendronate sodium are dependent on patient adherence to very specific guidelines regarding use. This study aims to estimate the rational use of alendronate sodium in the elderly. Methods: This is a cross-sectional study carried out with a structured questionnaire containing form of use and occurrence of adverse events related to alendronate sodium. The patients were recruited in their own homes. Rational use was considered as being the participants who: a) took the tablet in the morning; b) were fasting; c) waited at least 30 minutes before eating; d) ingested with a full glass of water; e) ingested the whole tablet; f) and remained in the orthostatic position for at least 30 minutes after use. Additionally, the odds ratio (OR) was used to analyze the association between the irrational use of alendronate sodium and the independent variables. Results and Discussion: Of the 248 participants in the study, most of the participants administered the medication in the morning (95.2%), with fasting (89.1%), waited at least 30 minutes to eat the first meal of the day (87.9%), and were in the orthostatic position until the time of the first meal (78.6%), but less than half ingested the tablet with a full glass of water (43.6%). Rational use of the medication was observed in only 30.7% of the participants. Regarding possible adverse events, 13.3% of the participants reported some event. Among the most prevalent were dry cough (6.5%), stomach pain (5.2%) and some throat discomfort (4.8%). The irrational use of this medication is associated with age and education level. Conclusion: The prevalence of irrational use of alendronate sodium in the elderly is high, and this use is associated with patients' sociodemographic factors.

Introdução: A efetividade e segurança do alendronato de sódio são dependentes da adesão dos pacientes em relação às orientações específicas sobre o uso. Assim, este trabalho, tem como objetivo estimar a racionalidade de uso do alendronato de sódio em idosos. Metodologia: Trata-se de um estudo transversal realizado através de um questionário estruturado contendo a forma de utilização e a ocorrência de eventos adversos relacionados ao uso do medicamento. Os pacientes foram recrutados em suas próprias casas. Considerou-se uso racional os participantes que: a) tomaram o comprimido pela manhã; b) em jejum; c) esperaram pelo menos 30 minutos para se alimentar; d) ingeriu com um copo cheio de água; e) ingeriu o comprimido inteiro; f) e permaneceu na posição ortostática por pelo menos 30 minutos após o uso. Adicionalmente, o odds ratio (OR) foi utilizado para analisar associação entre o uso irracional do alendronato de sódio e as variáveis independentes. Resultados e Discussão: Dos 248 participantes do estudo a maioria administravam o medicamento pela manhã (95,2%), em jejum (89,1%), aguardavam pelo menos 30 minutos para realizar a primeira refeição do dia (87,9%), ficavam em posição ortostática até o horário da primeira refeição (78,6%), porém menos da metade ingeria o comprimido com um copo cheio de água (43,6%). O uso racional do medicamento foi observado em apenas 30,7% dos participantes. Em relação aos possíveis eventos adversos, 13,3% dos participantes relataram algum evento. Dentre os mais prevalentes, destacaram-se a tosse seca (6,5%), dor de estômago (5,2%) e algum desconforto na garganta (4,8%). O uso irracional deste medicamento está associado à idade e ao nível de escolaridade. Conclusão: É elevada a prevalência de uso irracional do alendronato de sódio em idosos e este uso está associado a fatores sociodemográficos dos pacientes.

Pharmacist-led medication reconciliation at patient discharge: A scoping review.

BACKGROUND: One of the strategies to promote patient safety in care transitions is medication reconciliation (MR), which is conducted by the pharmacist at the patient's discharge from hospital. However, there are divergences about this process and about the pharmacist's role in conducting such intervention. OBJECTIVE: To systematically review the literature that reports the MR process led by pharmacists at patient discharge and map the different methods, strategies and tools used in the process. METHODS: Relevant studies were searched in the following databases: EMBASE, MEDLINE (PubMed), The Cochrane Library, and LILACS. No language restriction or publication date was applied. The studies considered eligible were those involving and describing pharmacist-led MR processes at acute patient discharge from hospital, with an experimental, quasi-experimental, or observational design. The characteristics of the studies and the MR processes were identified and then a qualitative synthesis was performed. RESULTS: Fifty studies were included. The majority of them were observational ones (82%), and the main outcome was medication discrepancies (42%). The studies were mostly conducted in university hospitals (70%) and in internal medicine wards (54%). Pharmacists were responsible mainly for gathering medication histories (72%), and identifying (96%) and solving (98%) pharmacotherapeutic problems. The main sources of information on pre-admission medications were patient/caregiver interviews (66%) and records from other care providers (40%). Only 30% of the studies described a patient discharge plan, and 14% shared information of the patient's pharmacotherapy with community pharmacists. CONCLUSION: The concept of MR and the pharmacist-led activities in the process varied in the literature, as well as the pharmacotherapy assessment focus and the communication strategies towards patients and other care providers, showing that standardization of the process and concepts is necessary.

Alterações farmacocinéticas de antimicrobianos em situações especiais: uma revisão narrativa / Antimicrobial pharmacokinetic changes in special situations: A narrative review

Até o ano de 1940, as doenças infecciosas eram uma das principais causas de morte no Brasil. Atualmente, apesar de um grande declínio, a mortalidade ainda é elevada em relação a países desenvolvidos e a outros países da América Latina. Dessa maneira, o objetivo do presente trabalho foi relatar as alterações fisiológicas em condições específicas, as consequências na farmacocinética dos antimicrobianos e ainda o impacto do ajuste de dose em tais situações. Realizou-se uma revisão narrativa de artigos publicados sobre a utilização de antimicrobianos nas seguintes situações: doença crítica e sepse, alcoolismo, tabagismo, extremos de idade, obesidade, nutrientes, polimorfismo genético, gravidez e lactação, insuficiência cardíaca, insuficiência hepática e renal. Observou-se que as alterações fisiológicas em tais situações afetam a farmacocinética dos antimicrobianos, modificando os processos de absorção, distribuição, metabolismo e excreção, os quais dependem muitas vezes da natureza do fármaco, podendo requerer ajuste de dose. Pôde-se concluir que as alterações observadas reduzem a precisão de uma dose terapêutica eficaz, evidenciando, dessa maneira, a importância do ajuste de dose.

Until the year 1940, infectious diseases were one of the main causes of death in Brazil. Currently, despite a large decline, mortality is still high in comparison to developed countries and other Latin American countries. Thus, the objective of the present study was to report the physiological changes under specific conditions, the consequences on the pharmacokinetics of antimicrobials and also the impact of the dose adjustment in such situations. A review of published articles on the use of antimicrobials was conducted in the following situations: critical illness and sepsis, alcoholism, smoking, age extremes, obesity, nutrients, genetic polymorphism, pregnancy and lactation, heart failure, hepatic and renal failure. It has been observed that the physiological changes in such situations affect the pharmacokinetics of antimicrobials, modifying the absorption, distribution, metabolism and excretion processes, and which often depend on the nature of the drug, which may require dose adjustment. It could be concluded that the observed changes reduce the accuracy of an effective therapeutic dose, thus evidencing the importance of the dose adjustment.

Linagliptin safety profile: A systematic review.

OBJECTIVE: To describe the safety profile of linagliptin. METHODOLOGY: Systematic review using PubMed/MEDLINE, BVS and Web of Science. The search strategy "Linagliptin" AND "safety" was used. The inclusion criteria were clinical trials with a control group composed of conventional DM2 pharmacotherapy. RESULTS: We identified 16 studies, and the most frequent adverse events (AEs) were nasopharyngitis with linagliptin at 5 and 10mg in monotherapy (31.6% and 29.6%, respectively) and gastrointestinal events (>10.0%) with linagliptin in combination. Of the AEs, 14.9 (±3.1)% were associated with the use of linagliptin in monotherapy, and 17.6 (±6.0)% in combination. The linagliptin AEs have a varied occurrence and frequency, ranging from mild to moderate intensity.
