RESUMO
This work investigated interactions ascribed to the administration of phytomedicines containing Valeriana officinalis and Piper methysticum with conventional drugs. The phytomedicines were characterized by HPLC and administered per os to male Wistar rats, either concomitantly or not with the CYP3A substrate midazolam. To distinguish between the presystemic or systemic effect, midazolam was given orally and intravenously. The effects on the P-gp substrate fexofenadine uptake by Caco-2 cells were examined. The valerenic acid content was 1.6 ± 0.1 mg per tablet, whereas kavain was 13.7 ± 0.3 mg/capsule. Valerian and kava-kava extracts increased the maximum plasma concentration (Cmax) of midazolam 2- and 4-fold compared to the control, respectively. The area under the plasma concentrations versus time curve (AUC(0-∞)) was enhanced from 994.3 ± 152.3 ng.h/mL (control) to 3041 ± 398 ng.h/mL (valerian) and 4139 ± 373 ng.h/mL (kava-kava). The half-life of midazolam was not affected. These changes were attributed to the inhibition of midazolam metabolism by the enteric CYP3A since the i.âv. pharmacokinetic of midazolam remained unchanged. The kava-kava extract augmented the uptake of fexofenadine by 3.5-fold compared to the control. Although Valeriana increased the uptake of fexofenadine, it was not statistically significant to that of the control (12.5 ± 3.7 ng/mg protein vs. 5.4 ± 0.3 ng/mg protein, respectively). Therefore, phytomedicines containing V. officinalis or P. methysticum inhibited the intestinal metabolism of midazolam in rats. Conversely, the P-gp-mediated transport of fexofenadine was preferably affected by kava-kava.

BACKGROUND: Low medication literacy is prevalent among older adults and is associated with adverse drug events. The Medication Literacy Test for Older Adults (TELUMI) was developed and content validated in a previously published study. AIM: To evaluate the psychometric properties and provide norms for TELUMI scores. METHOD: This was a cross-sectional methodological study with older adults selected from the community and from two outpatient services. Descriptive item-analysis, exploratory factor analysis (EFA), item response theory (IRT), reliability, and validity analysis with schooling and health literacy were performed to test the psychometric properties of the TELUMI. The classification of the TELUMI scores was performed using percentile norms. RESULTS: A total of 344 participants, with a mean age of 68.7 years (standard deviation = 6.7), were included; most were female (66.6%), black/brown (61.8%), had low schooling level (60.2%) and low income (55.2%). The EFA pointed to the one-dimensional structure of TELUMI. A three-parameter logistic model was adopted for IRT. All items had an adequate difficulty index. One item had discrimination < 0.65, and three items had an unacceptable guessing index (< 0.35) and were excluded. The 29-item version of TELUMI had excellent internal consistency (KR20 = 0.89). There was a positive and strong association between TELUMI scores and health literacy and education level. The scores were classified as inadequate medication literacy (≤ 10.0 points), medium medication literacy (11-20 points), and adequate medication literacy (≥ 21 points). CONCLUSION: The results suggest that the 29-item version of TELUMI is psychometrically adequate for measuring medication literacy in older adults.

This study aimed to analyze the toxic effects of Roundup Transorb® on the endangered Neotropical annual killifish Austrolebias charrua through the assessment of molecular and biochemical biomarkers. The fish were collected in temporary ponds and exposed to environmentally realistic concentrations of the herbicide (5 mg.L-1 for 96 h). The production of ROS, lipid peroxidation, DNA damage, and membrane fluidity were evaluated in the blood cells by flow cytometry. The mRNA expression of the antioxidant-related genes sod2, cat, gstα, atp1a1, gclc, and ucp1 across the brain, liver, and gills was quantified. The acute exposure of annual killifish to Roundup significantly increased ROS production, lipid peroxidation, and DNA damage in their erythrocytes. Likewise, Roundup Transorb® decreased membrane fluidity in the blood cells of the exposed fish. Gene expression analysis revealed that Roundup exposure alters the relative expression of genes associated with oxidative stress and antioxidant defense. Our results give rise to new insights into adaptive mechanisms of A. charrua in response to Roundup. Since Brazilian annual killifishes strongly risk extinction, this study paves the way for developing novel biotechnologies applied to environmental monitoring and aquatic toxicology assessment.

Dentre os 11 casos de erros com morte do paciente, oito traziam a informação sobre qual medicamento estava envolvido no erro, sendo seis deles considerados medicamentos potencialmente perigosos (MPP). Conclusão: os resultados do presente estudo apontam para a necessidade de implementação de melhorias nos estabelecimentos de saúde em geral farmácias, drogarias, hospitais, centros de saúde no que tange a prevenção de erros de medicação. Para isso, devem ser priorizadas iniciativas envolvendo os sistemas de medicação com elevada efetividade, sobretudo em contextos de situações de alto risco como uso de MPP e cuidado a pacientes em extremos etários
Aims: to identify and describe the news about medication errors that occurred in Brazil and were published in the Brazilian digital media. Methods: exploratory research, with data collected in news from digital media in Brazil, between 2015 and 2019. The search for news about medication errors was carried out on Google®. The cases published in the media were described according to the type and classification of the error, medication and professional involved in the occurrence of the error, characteristics of the patient who suffered the error and place where the error occurred. Results: of the 20 reported errors identified in the search, 11 cases of errors with death (55.0%), six cases of errors with harm (30.0%) and three cases of errors without harm (15.0%) were found. Of the 23 patients involved in the errors, 14 belonged to extreme age groups, nine pediatric patients (39.1%) and five geriatric patients (21.8%). As for the type of error, four reported cases involving prescription errors (20.0%), five reporting dispensing errors (25.0%), 10, administration errors (50.0%) and one involving concurrent dispensing and administration error (5.0%). Among the 11 cases of errors resulting in patient death, eight contained information about which medication was involved in the error, six of which were considered high alert medications. Conclusions: the results of this study point to the need to implement improvements in health institutions in general - pharmacies, drugstores, hospitals, health centers - with regard to the prevention of medication errors. For this, initiatives involving medication systems with high effectiveness should be prioritized, especially in contexts of high-risk situations such as the use of high alert medications and care for patients at extremes of age

A falta de uso de um medicamento necessário envolve riscos consideráveis para o idoso. Por meio da prestação de serviços de gerenciamento da terapia medicamentosa (GTM), os farmacêuticos podem contribuir na identificação de condições de saúde não tratadas que precisam de tratamento farmacológico. O objetivo deste estudo é descrever potenciais omissões de prescrição identificadas por farmacêuticos que cuidam de idosos na atenção primária brasileira e se elas estão incluídas na ferramenta START - Screening Tool to Alert to Right Treatment. Os dados foram coletados dos prontuários de 585 idosos acompanhados em serviços de GTM na atenção básica em Minas Gerais, Brasil, de 2014 a 2017. Os farmacêuticos identificaram a necessidade de adicionar pelo menos um medicamento para 28,4% dos pacientes idosos, totalizando 233 medicamentos relacionados a 31 diferentes problemas de saúde não tratados. Um terço (n = 79) dos medicamentos sugeridos pelos farmacêuticos correspondeu a algum critério proposto pela ferramenta START. Estes resultados enfatizam a importância do atendimento holístico ao paciente nos serviços de GTM.
The lack of use of a necessary medication involves considerable risks to the older person. Through the provision of comprehensive medication management (CMM) services, pharmacists may identify untreated health conditions that need pharmacological treatment. The purpose of this study is to describe potential prescribing omissions identified by pharmacists taking care of older adults in Brazilian primary care and whether they are included in the Screening Tool to Alert to Right Treatment (START). Data were collected directly from the records of 585 older adults followed up in CMM services in primary care in Minas Gerais, Brazil, from 2014-2017. Pharmacists identified the need to add at least one medication for 28.4 % of the older patients, totaling 233 drugs related to 31 different untreated health problems. One third (n=79) of the drugs suggested corresponded to some criterion proposed by START. These results emphasize the importance of holistic patient care in CMM services.
RESUMO
Avaliar os resultados clínicos de serviços de gerenciamento da terapia medicamentosa (GTM) oferecidos a pessoas vivendo com HIV (PVHIV) em uma unidade de dispensação de medicamentos brasileira. O estudo foi dividido em uma etapa transversal (etapa I), que avaliou o fator associado à identificação de dois ou mais problemas relacionados ao uso de medicamentos (PRM) na avaliação inicial; e uma etapa quasi- experimental (etapa II), realizada com um único grupo de pacientes para avaliar desfechos clínicosForam acompanhadas 52 PVHIV. A média de idade foi de 60±11,3 anos (min. = 29; máx. =78). A presença de dislipidemia (OR=5,38; IC 95%=1,61-17,97; p=0,006) e o uso de sete ou mais medicamentos (OR=4,28; IC 95%=1,32-13,88; p=0,015) foram fatores associados a identificação de dois ou mais PRM. Foi demonstrada uma diferença significativa entre os valores iniciais e finais de pressão arterial sistólica, carga viral do HIV, contagem de células T CD4+ e triglicerídeos (p<0,05). O serviço de GTM favoreceu os desfechos clínicos positivos.
To assess the clinical outcomes of comprehensive medication management (CMM) services offered to people living with HIV (PLHIV) at a Brazilian Antiretroviral Medication Dispensing Unit. The study was divided into a cross-sectional stage (stage I), to evaluate associated factor with the identification of two or more drug therapy problems (DTP) in the initial assessment; and a quasi-experimental stage (stage II), conducted with a single group of PLHIV to evaluate clinical outcomes. A total of 52 PLHIV, with 60±11.3 years of age were followed up. In stage I, the presence of dyslipidemia (OR=5.38; 95%CI=1.61-17.97) and the use of seven or more medications (OR=4.28; 95% CI=1.32-13.88) were factors associated with the identification of DTP. In stage II, a significant difference was demonstrated between the initial and final values of systolic blood pressure, triglycerides, HIV viral load and CD4+T-cells count (p<0,05). The CMM service favored positive clinical outcomes.
RESUMO
Melanoma is a skin cancer with a high mortality rate due to its invasive characteristics. Currently, immunotherapy and targeted therapy increase patient survival but are ineffective in the advanced stages of the tumor. Quercetin (Que) is a natural compound that has demonstrated chemopreventive effects against different types of tumors. This review provides evidence for the therapeutic potential of Que in melanoma and identifies its main targets. The Scopus, Web of Science, and PubMed databases were searched, and studies that used free or encapsulated Que in melanoma models were included, excluding associations, analogs, and extracts. As a result, 73 articles were retrieved and their data extracted. Que has multiple cellular targets in melanoma models, and the main regulated pathways are cell death, redox metabolism, metastasis, and melanization. Que was also able to regulate important targets of signaling pathways, such as PKC, RIG-I, STAT, and P53. In murine models, treatment with Que reduced tumor growth and weight, and decreased metastatic nodules and angiogenic vasculature. Several studies have incorporated Que into carriers, demonstrating improved efficacy and delivery to tumors. Thus, Que is a promising therapeutic agent for the treatment of melanoma; however, further studies are needed to evaluate its effectiveness in clinical trials.

Background: Peripheral nerve disease may lead to physical disability because of decreased muscle strength and/or loss of sensitivity in the dermatomes of affected peripheral nerves. Both human immunodeficiency virus (HIV)- and leprosy-affected patients can develop neurological damage; therefore, the coinfection of these diseases presents new challenges to the health care of these patients. Aims and Objective: This study aimed to investigate the motor alterations of patients coinfected with HIV and leprosy and their relationship with clinical and anthropometric characteristics, compared with individuals with isolated diseases. Materials and Methods: In this cross-sectional study, 90 individuals were divided equally into three groups: HIV/acquired immunodeficiency syndrome (AIDS) group, leprosy group and HIV/leprosy group. All individuals underwent an evaluation of muscle strength and upper limb endurance adjusted for the Brazilian standards, a palm print pressure test using a digital dynamometer and anthropometric measurements (weight, height and skin folds). Results: The HIV/leprosy group had the highest mean body mass index, followed by the leprosy group and the HIV/AIDS group. Skinfolds were similar between the groups. Multiple linear regression, adjusted for sex and age, revealed the coinfection of HIV and leprosy as possible contributor to a worse prognosis of muscle function, highlighting the bilateral reduction in the levels of palm print compression strengths compared with isolated diseases (HIV and leprosy). High CD4 count and shorter antiretroviral therapy duration were associated with worse indices of muscle strength, such as gripping and resistance, in coinfected patients. Conclusion: Patients coinfected with HIV and leprosy exhibited greater motor damage than those with isolated diseases. Thus, motor damage may be related to the sum of the neurological manifestations of the two morbidities.
RESUMO
This study aimed at evaluating the coefficients of total tract apparent digestibility (CTTAD) of nutrients, metabolisable energy (ME), diet palatability, faecal fermentative products and microbiota of dogs fed yeasts from different fermentation media and its fractions. Four diets were evaluated: control, without yeast (CO); diet with 10 g/kg brewer's yeast (BY); diet with 10 g/kg brewer's yeast + corn yeast (BCY); and diet with 10 g/kg BCY + cell wall fractions (BCYF). Twelve adult dogs were distributed in a randomized block design (periods). Each of the four diets was fed to a group of three dogs per period of 20 days, totalling two periods and six repetitions per treatment. Sixteen adult dogs were used for the palatability test, which compared the CO diet versus each one of the yeast diets. Data with normal distribution were subjected to analysis of variance (p < 0.05). Means were compared by orthogonal contrasts (p < 0.05): (A) CO diet versus BY, BCY and BCYF diets; (B) BY diet versus BCY and BCYF diets; (C) BCY diet versus BCYF diet. There was no difference in the CTTAD and ME of the diets (p > 0.05). Yeast diets reduced faecal odour and indole peak area (p < 0.05). Faecal short-chain fatty acids concentration was greater in dogs fed yeast diets compared to those fed the CO (p < 0.05). Yeast diets showed a higher intake ratio compared to the CO (p < 0.05). The BCY and BCYF diets resulted in a greater abundance of Bacteroides, Faecalibacterium, Coprococcus, and Phascolarctobacterium in relation to the CO (p < 0.05). Our results suggest that dietary yeast supplementation results in beneficial changes in intestinal functionality indicators, mainly with the combination of yeasts from brewers and corn fermentation media. In addition, yeast supplementation improves diet palatability without compromising nutrient digestibility.

Rhabdomyolysis is characterized by muscle damage and leads to acute kidney injury (AKI). Clinical and experimental studies suggest that glycogen synthase kinase 3ß (GSK3ß) inhibition protects against AKI basically through its critical role in tubular epithelial cell apoptosis, inflammation and fibrosis. Treatment with a single dose of lithium, an inhibitor of GSK3ß, accelerated recovery of renal function in cisplatin and ischemic/reperfusion-induced AKI models. We aimed to evaluate the efficacy of a single dose of lithium in the treatment of rhabdomyolysis-induced AKI. Male Wistar rats were allocated to four groups: Sham, received saline 0.9% intraperitoneally (IP); lithium (Li), received a single IP injection of lithium chloride (LiCl) 80 mg/kg body weight (BW); glycerol (Gly), received a single dose of glycerol 50% 5 mL/kg BW intramuscular (IM); glycerol plus lithium (Gly+Li), received a single dose of glycerol 50% IM plus LiCl IP injected 2 hours after glycerol administration. After 24 hours, we performed inulin clearance experiments and collected blood / kidney / muscle samples. Gly rats exhibited renal function impairment accompanied by kidney injury, inflammation and alterations in signaling pathways for apoptosis and redox state balance. Gly+Li rats showed a remarkable improvement in renal function as well as kidney injury score, diminished CPK levels and an overstated decrease of renal and muscle GSK3ß protein expression. Furthermore, administration of lithium lowered the amount of macrophage infiltrate, reduced NFκB and caspase renal protein expression and increased the antioxidant component MnSOD. Lithium treatment attenuated renal dysfunction in rhabdomyolysis-associated AKI by improving inulin clearance and reducing CPK levels, inflammation, apoptosis and oxidative stress. These therapeutic effects were due to the inhibition of GSK3ß and possibly associated with a decrease in muscle injury.

BACKGROUND: Dietary sodium is a well-known risk factor for cardiovascular and renal disease; however, direct evidence of the longitudinal changes that occur with aging, and the influence of dietary sodium on the age-associated alterations are scarce. METHODS: C57BL/6 mice were maintained for 13 months on a low (LS, 0.02 % Na+), normal (NS, 0.3 % Na+) or high (HS, 1.6 % Na+) salt diet. We assessed 1) the longitudinal trajectories for two markers of cardiovascular and renal dysfunction (blood pressure (BP) and albuminuria), as well as hormonal changes, and 2) end-of-study cardiac and renal parameters. RESULTS: The effect of aging on BP and kidney damage did not reach significance levels in the LS group; however, relative to baseline, there were significant increases in these parameters for animals maintained on NS and HS diets, starting as early as month 7 and month 5, respectively. Furthermore, changes in albuminuria preceded the changes in BP relative to baseline, irrespective of the diet. Circulating aldosterone and plasma renin activity displayed the expected decreasing trends with age and dietary sodium loading. As compared to LS - higher dietary sodium consumption associated with increasing trends in left ventricular mass and volume indices, consistent with an eccentric dilated phenotype. Functional and molecular markers of kidney dysfunction displayed similar trends with increasing long-term sodium levels: higher renovascular resistance, increased glomerular volumes, as well as higher levels of renal angiotensin II type 1 and mineralocorticoid receptors, and lower renal Klotho levels. CONCLUSION: Our study provides a timeline for the development of cardiorenal dysfunction with aging, and documents that increasing dietary salt accelerates the age-induced phenotypes. In addition, we propose albuminuria as a prognostic biomarker for the future development of hypertension. Last, we identified functional and molecular markers of renal dysfunction that associate with long-term dietary salt loading.

A pandemia da COVID-19 trouxe desafios para o monitoramento de usuários de anticoagulantes, sobretudo idosos, sendo o telemonitoramento uma alternativa para dar continuidade aos cuidados para esses pacientes. O presente estudo teve como objetivo descrever a experiência do telemonitoramento de idosos usuários de anticoagulantes na pandemia da COVID-19. Trata-se de estudo referente ao serviço farmacêutico de telemonitoramento de idosos (≥60 anos) em uso de anticoagulantes orais em ambulatório de geriatria privado (Belo Horizonte). Idosos tiveram parâmetros de efetividade e segurança dos anticoagulantes monitorados mensalmente por telefone (abr-dez/2021). Problemas identificados geraram intervenções ao paciente ou equipe multiprofissional. Ao total 425 idosos foram incluídos no serviço. A maioria usava apixabana (189;41,9%), rivaroxabana (146;34,4%) e varfarina (47;11,1%). Observou-se média de idade de 82,1 anos, maioria feminina (65,2%), maioria com alto risco de vulnerabilidade (69%), e incidência de 9,9% de COVID-19. Realizou-se 219 intervenções relativas à varfarina (média de 4,6 intervenções/paciente); referiram-se à solicitação de exame de RNI (57,5%), orientações em saúde (19,6%), alteração da dose (redução - 10,5%; aumento - 5,9%; suspensão - 0,6%), ou encaminhamento (5,9%). Usuários de outros anticoagulantes não apresentaram alterações nos parâmetros acompanhados. Onze idosos sofreram quedas e 10 demandaram internação por eventos tromboembólicos ou hemorrágicos. Não houve diferença estatisticamente significativa nas proporções de internação entre usuários de varfarina ou outros anticoagulantes (p=0,314). Acompanhar idosos usuários de anticoagulantes é importante, sobretudo considerando-se o alto nível de fragilidade identificado e os riscos tromboembólicos e não-tromboembólicos que a COVID-19 traz. O telemonitoramento foi importante, permitindo realização de múltiplas intervenções.
The COVID-19 pandemic brought challenges to the monitoring of anticoagulant users, especially older adults, making telemonitoring an alternative to provide continuity of care for these patients. The present study aimed to describe the experience of telemonitoring of older anticoagulant users during the COVID-19 pandemic. This is a descriptive study concerning the telemonitoring pharmaceutical service for older adults (≥60 years old) using oral anticoagulants in a private geriatric outpatient clinic (Belo Horizonte). Older people had parameters of effectiveness and safety of anticoagulants monitored monthly by telephone (Apr-Dec/2021). Identified problems generated interventions for the patient or the multidisciplinary team. A total of 425 older adults were included in the service. Most used apixaban (189;41.9%), rivaroxaban (146;34.4%) and warfarin (47;11.1%). There was a mean age of 82.1 years, mostly female (65.2%), most at high risk of vulnerability (69%), and an incidence of 9.9% of COVID-19. There were 219 interventions related to warfarin (average of 4.6 interventions/patient); including requests for an INR test (57.5%), health guidelines (19.6%), dosage change (reduction - 10.5%; increase - 5.9%; suspension - 0.6%), or referral (5.9%). Users of other anticoagulants did not show alterations in the monitored parameters. Eleven older adults suffered falls and 10 required hospitalizations due to thromboembolic or hemorrhagic events. There was no statistically significant difference in hospitalization rates between users of warfarin or other anticoagulants (p=0.314). Monitoring older anticoagulant users is important, especially considering the high level of frailty identified and the thromboembolic and non-thromboembolic risks that COVID-19 brings. Telemonitoring was important, allowing for multiple interventions to be performed.
RESUMO
OBJECTIVE: To investigate the use of sedatives by older adults attending a private outpatient geriatric clinic in Belo Horizonte (MG), Brazil, and its association with falls and hip fractures. METHODS: Using a longitudinal design, the prevalence of benzodiazepine and nonbenzodiazepine ("z-drugs") intake by older adults was described and their association with the incidence of falls and fractures (30 days after the initial visit) was evaluated through logistic regression. RESULTS: A total of 7821 older adults were included in the study, most of them women (72.50%), with a mean age of 77.5 years and a mean Clinical-Functional Vulnerability Index (IVCF-20) score of 16.5. The overall prevalence of sedative use (any sedative) was 6.19%, with 4.48% benzodiazepines and 1.98% z-drugs. The most widely used sedatives were clonazepam (29.04%), zolpidem (28.65%), and alprazolam (23.44%). Falls were reported for 182 patients (2.33%), with a higher incidence among users of any sedatives (4.34; p = 0.002; OR = 1.94, adjusted for sex, age, and IVCF-20) and benzodiazepines (5.14%; p < 0.001; OR = 2.28) than among non-users (2.19%). Hip fractures occurred in 33 patients (0.42%), and again were more frequent among users of sedatives (1.03%; p = 0.032; OR = 2.57) and benzodiazepines (1.43%; p = 0.003; OR = 3.45) than among non-users (0.38%). CONCLUSIONS: The use of sedatives, especially benzodiazepines, is associated with an increased incidence of falls and hip fractures in older adults
OBJETIVO: Investigar a utilização de sedativos entre idosos atendidos em ambulatório privado de geriatria em Belo Horizonte (MG), bem como sua associação com quedas e fraturas de fêmur. METODOLOGIA: Trata-se de estudo longitudinal, no qual foi descrita a prevalência de uso de benzodiazepínicos e drogas Z entre idosos (60 anos ou mais) e avaliada sua associação com a incidência de queda e fratura (30 dias após consulta inicial) por meio de regressão logística. RESULTADOS: Foram incluídos no estudo 7821 idosos, com maioria feminina (72,50%), idade média de 77,5 anos e Índice de Vulnerabilidade Clínico Funcional (IVCF-20) médio de 16,5 pontos. A prevalência de uso de sedativos em geral foi de 6,19%, sendo 4,48% de benzodiazepínicos e 1,98% de drogas Z. Os medicamentos sedativos mais utilizados foram clonazepam (29,04%), zolpidem (28,65%) e alprazolam (23,44%). Relatou-se queda para 182 idosos (2,33%), com incidência maior entre usuários de sedativos (4,34; p = 0,002; OR = 1,94 ajustada por sexo, idade e IVCF-20) e de benzodiazepínicos (5,14%; p < 0,001; OR = 2,28) do que entre não usuários (2,19%). Identificou-se fratura de fêmur em 33 idosos (0,42%), sendo mais frequente entre usuários de sedativos (1,03%; p = 0,032; OR = 2,57) e de benzodiazepínicos (1,43%; p = 0,003; OR = 3,45) do que entre não usuários (0,38%). CONCLUSÃO: Concluiu-se que a incidência de quedas e fraturas de fêmur em idosos possui associação com o uso de medicamentos sedativos, em especial os benzodiazepínicos

Resumo A divisão sexual do trabalho ocasiona iniquidade entre gêneros, bem como situações de violência direcionadas às mulheres no ambiente laboral. Na área farmacêutica, a maioria feminina e a inserção em múltiplos cenários, que envolvem contato com público e parcerias profissionais diferenciadas, potencializam a exposição à violência. Assim, o objetivo deste estudo foi analisar situações de violência vivenciadas por farmacêuticas no ambiente laboral. Para tal, utilizou-se método qualitativo, com análise de conteúdo, realizada no software NVivo®, de uma survey on line, respondida por farmacêuticas (n=381) registradas no Conselho Regional de Farmácia de Minas Gerais, Brasil. Como resultado, identificou-se quatro categorias: 'Convivendo com o desrespeito, ameaças e vulnerabilidade', 'O sexismo e o machismo estrutural que cala, diminui e atordoa', 'A discriminação contra a mulher como obstáculo à equidade' e 'Assédio sexual e objetificação da mulher'. Emergiram diversas expressões de violências no ambiente laboral provenientes de múltiplos agressores. Farmacêuticas reconheceram prejuízo profissional e pouco reconhecimento pela capacidade técnica. Conclui-se que os relatos expuseram a falta de proteção da integridade farmacêutica no ambiente de trabalho. Espera-se que esses resultados tragam à luz a desigualdade de gênero no trabalho farmacêutico, com destaque para situações de violência, ampliando a discussão e proporcionando evolução dessa profissão majoritariamente feminina.
Abstract The sexual division of labor causes inequality between genders, as well as situations of violence directed to women in the workplace. In the pharmaceutical area, the majority of women and insertion in multiple scenarios, involving contact with public and differentiated professional partnerships, enhance exposure to violence. Thus, the objective of this study was to analyze situations of violence experienced by pharmacists in the workplace. For this, a qualitative method was used, with content analysis, performed in the NVivo® software, of an online survey, answered by pharmacists (n=381) registered in the Regional Pharmacy Council of Minas Gerais, Brazil. As a result, four categories were identified: 'Living with disrespect, threats and vulnerability,' 'Sexism and structural chauvinism that shuts down, diminishes and torments,' 'Discrimination against women as an obstacle to equity' and 'Sexual harassment and objectification of women.' Several expressions of violence in the labor environment emerged from multiple aggressors. Pharmacists recognized professional impairment and little recognition for technical capacity. We concluded that the reports exposed the lack of protection of pharmaceutical integrity in the workplace. It is expected that these results bring to light the gender inequality in pharmaceutical work, with emphasis on situations of violence, expanding the discussion and providing evolution of this mostly female profession.
Resumen La división sexual del trabajo ocasiona iniquidad entre los géneros, así como situaciones de violencia dirigidas a las mujeres en el entorno laboral. En el ámbito farmacéutico, la mayoría de las mujeres y la inserción en múltiples escenarios, que implican contacto con el público y asociaciones profesionales diferenciadas, potencian la exposición a la violencia. Por lo tanto, el objetivo de este estudio fue analizar las situaciones de violencia experimentadas por las farmacéuticas en el entorno laboral. Para esto, se utilizó un método cualitativo, con análisis de contenido, realizado en el software NVivo®, de una encuesta en línea, respondida por farmacéuticas (n=381) registradas en el Consejo Regional de Farmacia de Minas Gerais, Brasil. A consecuencia, se identificaron cuatro categorías: 'Conviviendo con falta de respeto, amenazas y vulnerabilidad', 'el sexismo y el machismo estructural que cala, disminuye y atormentó', 'la discriminación contra la mujer como obstáculo a la equidad' y 'el acoso sexual y la objeción de la mujer'. Han surgido varias expresiones de violencia en el entorno laboral procedentes de múltiples agresores. Los productos farmacéuticos han reconocido el daño profesional y el escaso reconocimiento de la capacidad técnica. Se concluye que los informes haciendo hincapié de manifiesto la falta de protección de la integridad farmacéutica en el entorno laboral. Se espera que estos resultados traigan a la luz la desigualdad de género en el trabajo farmacéutico, haciendo hincapié en las situaciones de violencia, ampliando el debate y dando lugar a la evolución de esa profesión principalmente femenina.

Increasing the energy content of animal feed aims to enhance productive performance and improve carcass finishing. However, when randomly performed, this action can result in gastrointestinal dysfunctions that impair performance. One way to avoid such dysfunctions is to supplement the animal feed with Saccharomyces cerevisiae yeast. The present study aimed to evaluate the effect of Saccharomyces cerevisiae, as a yeast culture or autolyzed yeast, on ingestive behavior, apparent feed digestibility, productive performance, and carcass traits of feedlot finished steers. Thirty-six ½ Angus x ½ Nellore animals with 369 ± 4 kg average initial body weight were used. The experiment lasted 133 days: 28 days for adaptation to the experimental diets and facilities, four evaluation periods, three of which with 28 days, and a fourth period with 21 days. The experimental design was a completely randomized block with three treatments and six replications. The treatments were a yeast-free diet (Control), a diet with yeast culture (7 g animal-1 day-1), and a diet with autolyzed yeast (7 g animal-1 day-1). The experimental diet consisted of 400 g kg-1 corn silage and 600 g kg-1 concentrate on a dry matter basis. Animals supplemented with yeast culture spent more time ruminating and showed higher apparent digestibility of dry matter (5.94 hours day-1 and 74.67%, respectively). Supplementation with yeast culture resulted in greater daily weight gains in animals from 0-56, 0-84, and 0-105 experimental days (1.661, 1655, and 1.667 kg day-1, respectively) than animals that received autolyzed yeast, and those that received no additive, as well as feed conversion was better for these animals. Daily and experimental carcass gains were higher for animals that received yeast culture (1.119 kg day-1, and 117.5 kg, respectively). Animals supplemented with yeast culture had greater fat thickness in the Longissimus dorsi, in the rib region, and greater subcutaneous fat gain throughout the finishing period (5.61, 6.25, and 3.04 mm, respectively). The supply of yeast culture is recommended during the finishing phase as it improves feed digestibility and promotes greater weight gain, carcass gain, and greater subcutaneous fat deposition.(AU)
Elevar o teor energético da ração dos animais tem por intuito potencializar o desempenho produtivo e promover melhor acabamento nas carcaças. No entanto, esta ação quando realizada ao acaso pode gerar disfunções no trato gastrointestinal que comprometem o desempenho. Uma forma de evitar tais disfunções é administrar leveduras Saccharomyces cerevisiae de forma suplementar na ração dos animais. O objetivo do presente estudo foi avaliar o efeito do uso de Saccharomyces cerevisiae, como cultura de leveduras ou como levedura autolisada, no comportamento ingestivo, digestibilidade aparente da ração, desempenho produtivo e as características de carcaça de novilhos terminados em confinamento. Foram utilizados 36 animais ½ Angus x ½ Nelore com peso corporal médio inicial de 369 ± 4 kg. O experimento teve duração de 133 dias divididos em 28 dias de adaptação às rações e instalações experimentais, e quatro períodos de avaliação, sendo três períodos de 28 dias e um quarto período de 21 dias. O delineamento experimental foi de blocos inteiramente casualizados com três tratamentos e seis repetições. Os tratamentos foram: ração sem leveduras (Controle); ração com cultura de leveduras (7 g animal-1 dia-1); e ração com levedura autolisada (7 g animal-1 dia-1). A ração experimental foi constituída por 400 g kg-1 silagem de milho e 600 g kg-1 concentrado em base de matéria seca. Os animais suplementados com cultura de leveduras permaneceram mais tempo ruminando e apresentaram maior digestibilidade aparente da matéria seca em relação aos demais (5,94 horas dia-1 e 74,67%, respectivamente). O uso de cultura de leveduras promoveu maiores ganhos de peso diário de 0-56, 0-84 e de 0-105 dias (1,661, 1655 e 1,667 kg dia-1, respectivamente) em relação aos animais que receberam levedura autolisada e aos que não receberam nenhum aditivo, assim como a conversão alimentar foi melhor para estes animais. Os ganhos de carcaça diário e do período experimental foram superiores para os animais que receberam cultura de leveduras em suas rações (1,119 kg dia-1 e 117,5 kg respectivamente). Os animais suplementados com cultura de leveduras possuíram maior espessura de gordura no Longissimus dorsi, na região do costilhar e maior ganho de gordura subcutânea ao longo do período de terminação (5,61, 6,25 e 3,04 mm, respectivamente). O uso da cultura de leveduras na fase de terminação é recomendado, pois melhora a digestibilidade da ração e promove maior ganho de peso, ganho de carcaça e maior deposição de gordura subcutânea.(AU)

Acute kidney injury (AKI) alters renal hemodynamics, leading to tubular injury, activating pathways of inflammation, proliferation, and cell death. The initial damage caused to renal tissue after an ischemia/reperfusion (I/R) injury exerts an important role in the pathogenesis of the course of AKI, as well as in the predisposition to chronic kidney disease. Vitamin D deficiency has been considered a risk factor for kidney disease and it is associated with tubulointerstitial damage, contributing to the progression of kidney disease. Obesity is directly related to diabetes mellitus and hypertension, the main metabolic disorders responsible for the progression of kidney disease. Furthermore, the expansion of adipose tissue is described as an important factor for increased secretion of pro-inflammatory cytokines and their respective influence on the progression of kidney disease. We aimed to investigate the influence of vitamin D deficiency and obesity on the progression of renal disease in a murine model of renal I/R. Male Wistar rats underwent renal I/R surgery on day 45 and followed until day 90 of the protocol. We allocated the animals to four groups according to each diet received: standard (SD), vitamin D-depleted (VDD), high fat (HFD), or high fat vitamin D-depleted (HFDV). At the end of 90 days, we observed almost undetectable levels of vitamin D in the VDD and HFDV groups. In addition, HFD and HFDV groups presented alterations in the anthropometric and metabolic profile. The combination of vitamin D deficiency and obesity contributed to alterations of functional and hemodynamic parameters observed in the HFDV group. Moreover, this combination favored the exacerbation of the inflammatory process and the renal expression of extracellular matrix proteins and phenotypic alteration markers, resulting in an enlargement of the tubulointerstitial compartment. All these changes were associated with an increased renal expression of transforming growth factor ß and reduced expression of the vitamin D receptor. Our results show that the synergistic effect of obesity and vitamin D deficiency exacerbated the hemodynamic and morphological changes present in the evolution of renal disease induced by I/R.
RESUMO
Tuberculosis (TB) is a disease of great relevance, responsible for 1.5 million deaths worldwide. Therefore, actions to control TB are necessary, and pharmacists may play an important role, especially in primary healthcare (PHC), where the diagnosis and management of this infection occurs. In a large Brazilian city, pharmacotherapeutic follow-up in PHC has been offered by pharmacists to people with TB since 2018. The objective of this study was to evaluate the implementation and effectiveness of this service though a longitudinal type 1 effectiveness-implementation hybrid study. Data were collected from January 2018 to February 2020 in the pharmaceutical services system. The service indicators were described and effectiveness was evaluated using Poisson regression analysis to compare the incidence of cure among patients using and not using the service. The service was performed in 148 PHC units by 82 pharmacists. Of the total of 1076 treatments, 721 were followed up by pharmacists, and TB was cured more frequently in these cases (90.4% attended vs. 73.5% unattended). The adjusted hazard ratio of cure among patients enrolled in the pharmacotherapeutic follow-up service was 2.71 (2.04-3.61; p < 0.001). Pharmacotherapeutic follow-up for people with TB significantly increased the incidence of cure and should be encouraged.

Comprehensive medication management (CMM) is the service offered within the clinical practice of pharmaceutical care, which has the objective to optimize pharmacotherapeutic outcomes. Patient satisfaction is a multidimensional construct that points to the quality of the health services offered and the degree to which the patients' expectations and needs are met. The evaluation of the level of patient satisfaction is a key indicator to support decisions and to improve the quality of the service provided. This study aims to describe the protocol for a scoping review to map the instruments to measure patient satisfaction with CMM services and compare them according to their development characteristics and the applicability of patient-reported outcome measures. The literature search will be conducted using the scoping review methodology, proposed by the Joanna Briggs Institute and the PRISMA Extension for Scoping Reviews (PRISMA-ScR) method. The results will be presented in two sessions: (1) description of the search strategy; and (2) the characteristics of the satisfaction instruments, number of items and questions related to the conceptual model, content validity, construct validity, reliability, score/interpretation, and respondent burden. This review will shed light on the available satisfaction measurement instruments, allowing existing gaps to be identified for future research.
RESUMO
OBJECTIVE: To describe the consumption of psychotropic drugs in the adult population residing in Brumadinho, Minas Gerais, after the Vale dam collapse, which occurred in 2019. METHODS: This is a cross-sectional study, part of the Brumadinho Health Project, developed in 2021, with a representative population-based sample of adults (18 years and over) residing in Brumadinho. A total of 2,805 adults with information on self-reported use of psychotropic drugs (antidepressants and anxiolytics-hypnotics/sedatives) in the last 15 days were included in the analysis. The prevalence of psychotropic drug use was estimated, and the most used psychotropic drugs were identified. Pearson's chi-square test (with Rao-Scott correction) was used to test associations between exposures and use of psychotropic drugs, considering a significance level of p<0.05. RESULTS: The use of antidepressants (14.2%) was more common than the use of anxiolytics or hypnotics/sedatives (5.2%), with sertraline and fluoxetine being the most used antidepressants. The use of anxiolytics and hypnotics/sedatives was higher among residents who lived in the area directly affected by the dam's mud, and the use of any psychotropic drug was higher among those who lost a relative/friend in the disaster and assessed that their health worsened after the disaster, and among women. CONCLUSION: The results of the study corroborate what was observed in other populations exposed to similar tragedies, regarding the pattern of associations and the of use of psychotropic drugs.
