Exploring the neuroprotective potential of antimicrobial peptides from Dinoponera quadriceps venom against pentylenetetrazole-induced seizures in vivo.

Epilepsy affects around 50 million people worldwide and 30% of patients have difficulty controlling the disease. The search for substances that can fill the existing gaps in the treatment of epilepsy is of great importance. Arthropod venoms are promising sources for this purpose due to the presence of small peptides that modulate the activity of ion channels and neuron receptors. The aim of this study was to investigate dinoponeratoxins from the Dinoponera quadriceps ant venom (M-PONTX-Dq3a, M-PONTX-Dq3b and M-PONTX-Dq3c) as potential anticonvulsants. We evaluated them in a seizure model induced by pentylenetetrazole (PTZ) in male swiss mice. Interestingly, intraperitoneal treatment with each peptide increased the time until the first seizure and the percentage of survival, with M-PONTX-Dq3b showing the best results. M-PONTX-Dq3a was discarded due to the appearance of some signs of toxicity with the increase in malondialdehyde (MDA) levels in the striatum. Both, M-PONTX-Dq3b and M-PONTX-Dq3c decreased iNOS and TNF-α in the hippocampus. Notably, M-PONTX-Dq3c treatment decreased the levels of MDA and nitrite in the cortex and hippocampus. Our results indicate that, M-PONTX-Dq3b and M-PONTX-Dq3c have anticonvulsant activity and exhibit anti-inflammatory effects in epilepsy, offering new perspectives for biopharmaceutical development.

Fluoride concentration in teas derived from Camellia Sinensis produced in Argentina.

To evaluate the fluoride concentration and pH of tea derived from Camellia sinensis produced and commercialized in Argentina. Forty-eight varieties of tea (black (n = 16), green (n = 21), red (n = 7), and white (n = 4)) commercialized in the form of leaves or tea bags were acquired. One bag or 2.0 ± 0.05 g of each product was infused for 5 min in 200 mL of distilled boiled water. The F- concentration was determined using an ion-selective electrode and pH was measured using a pH meter. The found fluoride concentrations ranged from 0.1 to 9.7 µg/mL and the pH ranged from 2.7 to 5.1. A higher fluoride concentration was observed in the leaves group (2.75 ± 2.65 µg/mL) compared to tea bags (1.10 ± 0.82 µg/mL) (p < 0.05). Regarding the type of tea, green and black tea were richer in F- than red and white tea. Fluoride and pH appeared not to be correlated (Pearson test). All the studied tea samples presented fluoride concentrations greater than the threshold recommended for drinking water. The pH proved to be low, which could be a risk for erosive tooth wear.

Conclusions: The evidence found predisposes university students to risks in the face of this pandemic.

Salivary Fluoride Bioavailability after Brushing with Brazilian Red Propolis Dentifrice: A Clinical Study.

INTRODUCTION: Fluoride plays an important role in the control of dental caries, and currently new dentifrices are being associated with natural products. OBJECTIVE: This study aimed to evaluate the availability of fluoride in saliva samples after using a dentifrice incorporated with Brazilian red propolis (BRP, INPI Patent no. BR1020170110974) and to compare it to a conventional fluoridated dentifrice in healthy participants. METHODS: This study was conducted implementing a double-blind, randomized, controlled, and crossover design. Saliva samples of participants were collected at the following time points: 0 at baseline and 5, 15, 30, 45, and 60 minutes after brushing with each dentifrice. Salivary fluoride concentrations showed no statistically significant difference when comparing the two treatments (p > 0.05). All available fluoride concentrations in saliva decreased after one hour, with no significant difference between BRP and conventional fluoridated dentifrice treatment samples (p > 0.05). RESULTS: The results showed that there was no difference between the analyzed fluoride concentrations 1 hour after brushing with the different dentifrices. CONCLUSIONS: The results of this study suggest that the propolis incorporated in the dentifrice did not interfere with the kinetics and bioavailability of the fluoride ion in saliva samples, enabling its integration with the pharmaceutical formula and thereby promoting its anti-inflammatory and antimicrobial benefits without compromising the anticaries activity of the formulation.

Assessment of a clinical pharmaceutical service for hypertensive and/or diabetic patients in a primary healthcare center

Objectives: The present study aimed to assess the short- and long-term outcomes of a clinical service provided by a pharmacist structured in a primary healthcare center (PHC) in Fortaleza, Ceará, Brazil. Methods: A longitudinal-type study was conducted. Data were collected from pharmacotherapy follow-up (PTF) records from the Pharmaceutical Care Unit of the PHC Dr. Anastácio Magalhães. The PTF was provided to patients diagnosed with hypertension and/or diabetes mellitus. Two groups were formed: records of patients who intended to undergo six months or more of PTF (PTF group) and those who opted not to go through with it after the first session (control). In addition, new blood pressure and glucose measurements were obtained after invitation by phone call at least six months after the completion of the PTF to assess maintenance of the benefits gained. The control patients were invited for this new data collection as well for comparison purposes. Research Ethics Committee approval protocol no. 329.717. Results: A total of 224 patients were considered, 109 in the complete PTF group and 115 in the control group, where the following main results were obtained: systolic pressure (mean ± SD) went from 139.43±20.6 to 128.31±16.03 mmHg; diastolic pressure, from 82.45±11.44 to 77.68±9.21 mmHg; blood glucose, from151.78±75.8 to 121.39±47.56 mg/dL; and cardiovascular risk, from 21.59±9.42 to 18.95±9.06%. In comparison, the control group did not show significant changes on the above parameters. In the post-PTF analysis, the benefits gained tended to be maintained even at least six months after its conclusion. Conclusions: Thus, the findings of the present study suggest that the provision of the clinical pharmaceutical service assessed at the primary healthcare level offers benefits to patients who attended it for at least six months. Furthermore, the data also suggest that these benefits are maintained in the long term.

Medication errors in critical patients during medication reconciliation: analyses and clinical management

Abstract Medication errors (ME) are frequent in the admission of patients to the ICU and can be identified and prevented through medication reconciliation (MR). Our aim was to evaluate the incidence, type and severity of MEs and associated factors, identified during MR in the ICU. This is a prospective, analytical approach, performed in the ICU of a private hospital, where the MRs were evaluated from April to June 2016. The SPSS and Stata programs were used to analyse the data. Logistic regression was performed to determine the factors associated with MEs. MR was performed with 136 patients, of whom 126 (92.6%) used drugs regularly. The incidence of MEs was 16.3% (95% CI 11.5-21.2). The main classes of drugs involved were those acting on the nervous and cardiovascular systems. There were 128 pharmaceutical interventions (acceptance: 71.1%). Regarding severity, 65.5% (n=80) of the errors reached the patient, but there was no harm. The risk factors for MEs identified were: age ≥60 years, number of comorbidities >1 and previous use of drugs ≥9. The incidence of MEs found and the significant association with age, comorbidities and polymedication alert to the need for specific attention to prevent admission errors in the most susceptible patient groups.

Adverse reactions caused by antimicrobials in hospitalized pediatric patients: causality and avoidability analysis

Abstract In pediatrics, drug therapy is commonly performed through adaptations of the dosage forms to adult use, increasing the risk of adverse drug reactions. In this context, studies assessing the severity and avoidability of the adverse reactions in children, especially those caused by antimicrobials, are still scarce. This work aimed to investigate suspected antimicrobial adverse reactions (ATM-ADRs) in pediatric patients admitted to a public hospital in northeastern Brazil, focusing on causality and avoidability analysis. A cohort study was carried out over a period of six months in a 64-bed pediatric unit. The incidence of suspected adverse reactions caused by antimicrobials was 14.65%. Most reactions were rated as probable (89.13%), with moderate severity (84.78%) and possibly avoidable (45.65%). The analysis indicated that the use of a larger number of medications (p<0.0001) and longer hospital stay (p=0.004) were related to the occurrence of ATM-ADR. Our findings demonstrated that almost half of the suspected reactions could be prevented and that the antimicrobial's clinical management is relevant in this context. Besides, increasingly accurate adverse reaction classification instruments are essential. These results can support the development of therapeutic guidelines addressed to a safe and effective pharmacotherapy in the pediatric area

Camellia sinensis in Dentistry: Technological Prospection and Scientific Evidence.

PURPOSE: This study aimed to evaluate reports of patents for oral care formulations, based on Camellia sinensis (C. sinensis), deposited and granted in intellectual property banks. METHODS: A survey was conducted through collection, treatment, and analysis of extracted information from patent reports selected. The documentary research was conducted in January 2021 on formulations with C. sinensis for dental applications, including since the first patent deposits until the current time. The risk of bias of clinical trials with these formulations was analyzed to verify the scientific evidence. The data extracted represent the distribution of the number of patents by banks, annual evolution of patent deposits, applicant of patents by country, distribution of patents according to International Patent Classification codes, and the types of patented products. RESULTS: Data and information from 20 selected patents were extracted. The United States Patent and Trademark Office (USPTO) and World Intellectual Property Organization (WIPO) were the banks with the largest number of patents for products/formulations with C. sinensis for oral care applications with 7 (35%) and 6 (30%) patent registrations, respectively. Other banks did not provide patents related to the search. Patents of compositions were the largest with 14 filings, and the remainder of formulations are represented specially by mouthwashes and toothpastes. As for clinical application, 18 patents were filed as products with antimicrobial and antibiofilm action, while 2 patents are directed to the treatment of xerostomia. In general, the aspects of the studies of clinical efficacy pointed to a low risk of bias. CONCLUSION: The study pointed out a small number of products protected by patents for Camellia sinensis for oral care indication, highlighting mainly mouthwash compositions and formulations. In the methodological parameters of clinical trials carried out with the formulations, the majority pointed out a low risk of bias.

Antimicrobial Efficacy of Propolis-Containing Varnish in Children: A Randomized and Double-Blind Clinical Trial.

Dental caries is a sugar-dependent condition common in childhood, which causes microbiological imbalance in dental biofilm. The present study evaluated the antimicrobial efficacy of a 2.5% Brazilian Red Propolis (BRP) dental varnish to prevent caries in children. Seventy-five children with high caries risk, aged between 36 and 71 months and with no caries, were assigned to three groups to receive varnish treatment containing 2.5% BRP, 1% chlorhexidine, or 5% fluoride. The varnish was applied to the occlusal surfaces of the deciduous second molars on the first day of treatment (D1), after 90 days (D90), and 180 days of the start of treatment (D180). Saliva was collected to assess S. mutans before each varnish application and 180 days at the end of treatment (D360). Values were expressed in log10 (CFU/mL). Statistics were performed by applying repeated measures of variance analysis, Tukey's multiple comparisons test, and paired t-test. In the first dilution (1 : 10), there was microbial load reduction at the following periods: BRP in D0-D90 (p < 0.05) and D0-D180 (p < 0.01); fluoride in D0-D90 (p < 0.001); and chlorhexidine in D0-D180 (p < 0.05). In the second dilution (1 : 100), there was microbial load reduction in the groups at the following periods: BRP in D0-D90 (p < 0.05) and D0-D180 (p < 0.01); fluoride in D0-D180 (p < 0.05), and chlorhexidine in D0-180 (p < 0.01) and D0-360 (p < 0.05). The 2.5% BRP dental varnish was effective in decreasing S. mutans colonies in saliva when used within 90 days.

Is Riparin III a promising drug in the treatment for depression?

Stress is crucially related to the pathophysiology of mood disorders, including depression. Since the effectiveness and number of the current pharmacological options still presents significant limitations, research on new substances is paramount. In rodents, several findings have indicated that corticosterone administration induces the manifestation of behavioral and neurochemical aspects of depression. Recently, riparin III has shown antidepressant-like properties in trials performed on animal models. Thus, our goal was to investigate the effects of riparin III on behavioral tests, monoamines levels, oxidative stress and cytokines levels in chronic corticosterone-induced model of depression. To do this, female swiss mice were treated with subcutaneous administration of corticosterone for 22 days. In addition, for the last 10 days, riparin III or fluvoxamine were also administered per os in specific test groups. Control groups received subcutaneous saline injections or distilled water per os. At the end of the timeline, the animals were killed and their hippocampi, prefrontal cortex, and striatum dissected for neurochemical analysis. Brain changes following corticosterone administration were confirmed, and riparin III could reversed the most abnormal behavioral and neurochemical corticosterone-induced alterations. These results suggest the potential antioxidant, anti-inflammatory and antidepressant effects of riparin III after a chronic stress exposure.

Clinical and Antimicrobial Evaluation of Copaifera langsdorffii Desf. Dental Varnish in Children: A Clinical Study.

BACKGROUND: The objective of this study was to evaluate the clinical and microbiological efficacies of (C. langsdorffii) dental varnish in children at high risk of dental caries.. METHODS: This is a longitudinal, randomized, controlled clinical trial. Ninety high-risk caries-free children (ICDAS II = 0) were recruited and randomly divided into three groups: C. langsdorffii, chlorhexidine, or fluoride. The varnishes were applied on the second deciduous molars for three times: baseline (D0), after 90 days (D90), and after 180 days (D180). Saliva was collected on D0, D90, D180, and D360 to evaluate S. mutans reduction. Statistics were carried out by ANOVA, Tukey's test, and the paired t-test. RESULTS: Copaiba varnish demonstrated significant S. mutans reduction: D360 versus D0 (p < 0.0001), D180 versus D0 (p < 0.001), D360 versus D90 (p < 0.001), D180 versus D90 (p < 0.001), and D360 versus D180 (p < 0.05). Chlorhexidine varnish significantly reduced S. mutans at D180 versus D0 (p < 0.05). Fluoride reduced at D180 versus D0 (p < 0.001). CONCLUSIONS: Three annual applications of this varnish showed substantial antimicrobial activity against S. mutans and caries prevention for up to 12 months.

Inhibition of Staphylococcus aureus TetK and MsrA efflux pumps by hydroxyamines derived from lapachol and norlachol.

The present study aimed to evaluate the in vitro efflux pump inhibitory capacity of hydroxyamines derived from lapachol and norlachol, where compounds 3, 4, and 5 were tested against the S. aureus strains: RN4220 carrying the pUL5054 plasmid; and IS-58, endowed with the PT181 plasmid. The substances were synthesized from 2-hydroxy-quinones, lapachol and nor-lapachol obtaining the corresponding 2-methoxylated derivatives via dimethyl sulfate alkylation in a basic medium, which then reacted chemoselectively with 2-ethanolamine and 3-propanolamine to form the corresponding amino alcohols. The antibacterial action of the substances was quantified by determining the Minimum Inhibitory Concentration (MIC), while a microdilution assay was carried out to ascertain efflux pump inhibition of Staphylococcus aureus strains carrying the MsrA macrolide and the TetK tetracycline efflux pumps with the substances at a sub-inhibitory concentration. The results were subjected to statistical analysis by an ANOVA test and Bonferroni post hoc test. The MIC from the substances exhibited a value ≥ 1024 µg/mL. However, a significant reduction (p < 0.0001) of the erythromycin, tetracycline and ethidium bromide MIC was demonstrated when these were in combination with the substances, with this effect being due to a supposed efflux pump inhibition. The tested substances demonstrated effectiveness at decreasing the MIC of erythromycin, tetracycline and ethidium bromide, potentially by inhibiting the MsrA macrolide and the TetK tetracycline efflux pumps present in the tested S. aureus strains.

Understanding the provision of a clinical service in mental health and the role of the pharmacist: a qualitative analysis / Compreendendo a provisão de um serviço clínico na saúde mental e o papel do farmacêutico: uma análise qualitativa / Comprender la prestación de un servicio clínico en salud mental y el papel del farmacéutico: un análisis cualitativo

Pharmacists have important roles in mental health disease; however, their performance in Brazilian Psychosocial Care Centers (CAPS) is unknown. This qualitative study was conducted in a CAPS, Brazil; using interviews and analyzes from the perspective of Bardin, in which categories arising from the perceptions of patients and the health team emerged in relation to the provision of the medication review with follow up (MR) service and the role of the pharmacist in mental health. According to the participants, the MR service is essential and important because it allows professional recognition, beyond the identification of professional attributes of the pharmacists. Moreover, there was a duality in the pharmacist's role between the logistic and clinical attributes of mental health. Thus, this perception helps to elucidate the pharmacist's process of work in mental health and supports future strategies of action in this area. (AU)

Farmacêuticos têm papéis importantes na área da saúde mental; entretanto, sua atuação nos Centros de Atenção Psicossociais (CAPS) brasileiros é desconhecida. Este estudo qualitativo foi realizado em um CAPS, Brasil; utilizando-se de entrevistas e análises sob a perspectiva de Bardin, no qual categorias em relação à prestação do serviço de acompanhamento farmacoterapêutico (AFT) e ao papel do farmacêutico na saúde mental emergiram através das percepções dos pacientes e equipe de saúde. Segundo os participantes, o serviço de AFT é essencial e importante porque permite o reconhecimento profissional, além da identificação dos atributos profissionais dos farmacêuticos. Além disso, houve uma dualidade no papel do farmacêutico em relação aos atributos logísticos e clínicos na saúde mental. Assim, essas percepções ajudam a elucidar o processo de trabalho do farmacêutico em saúde mental, subsidiando futuras estratégias de ação nesta área. (AU)

Hospital Cost of Complications After Kidney Transplant.

BACKGROUND: Kidney transplant is considered the best treatment of rehabilitation for chronic kidney disease, but clinical and/or surgical complications may occur after transplant. The study aimed to assess the cost of complications after kidney transplant. MATERIALS AND METHODS: This is a descriptive, retrospective, and exploratory study that used data from Hospital Information System ("Sistema de Informação Hospitalar"). We identified the patients with records of kidney transplant in the states of northern and northeastern Brazil in 2013. These patients were followed up through the records, specifically from 2013 to 2017. The variables analyzed were sex, age, and period after transplant of readmissions (early, intermediate, or late), the main complications within 4 years after the kidney transplant, and cost of hospital admissions. RESULTS: There were 893 patients with records of kidney transplant in the regions of the study. During the follow-up period, 319 patients had complications. Most hospital readmissions involved male patients (63.6%; n = 203). Mean age was 45 (SD, 15.14) years. Patients developed complications mainly in the early period after transplant (70.22%; n = 224). The number of hospital admissions was 758. The main complications were regarding urinary tract (72.02%; n = 546), infections (19.79%; n = 150), and vascular and/or pulmonary (2.90%; n = 22). The total cost for the treatment of these complications was US $528,329.51. CONCLUSIONS: By analyzing the data it was possible to identify that there is a significant cost involved in the treatment of complications after kidney transplant.

The neuroprotective effect of Riparin IV on oxidative stress and neuroinflammation related to chronic stress-induced cognitive impairment.

BACKGROUND: Cognitive impairment is identified as one of the diagnostic criteria for major depressive disorder and can extensively affect the quality of life of patients. Based on these findings, this study aimed to investigate the possible effects of Riparin IV (Rip IV) on cognitive impairment induced by chronic administration of corticosterone in mice. METHODS: Female Swiss mice were divided into four groups: control (Control), corticosterone (Cort), Riparin IV (Cort + Rip IV), and Fluvoxamine (Cort + Flu). Three groups were administered corticosterone (20 mg/kg) subcutaneously during the 22-day study, while the control group received only vehicle. After the 14th day, the groups were administered medications: Riparin IV (Rip IV), fluvoxamine (Flu), or distilled water, by gavage, 1 h after the subcutaneous injections. After treatment, mice underwent behavioral testing, and brain areas were removed for oxidative stress and cytokine content assays. RESULTS: The results revealed that Cort-treated mice developed a cognitive impairment and exhibited a neuroinflammatory profile with an oxidative load and Th1/Th2 cytokine imbalance. Rip IV treatment significantly ameliorated the cognitive deficit induced by Cort and displayed a neuroprotective effect. CONCLUSION: The antidepressant-like ability of Rip IV treatment against chronic Cort-induced stress may be due to its potential to mitigate inflammatory damage and oxidative stress. The antioxidant and anti-inflammatory effect observed indicates Rip IV as a possible drug for antidepressant treatment of non-responsive patients with severe and cognitive symptoms.

AIM: To evaluate the efficacy of dentifrice containing brazilian red propolis (BRP) in adolescents under orthodontic treatment. Materials and Methods. This is a randomized, double-blind, clinical trial. A total of 92 participants free from caries were randomized into 2 groups; the first received fluoride dentifrice, and the second received fluoride dentifrice incorporated with BRP. The gingival bleeding index (GBI) was recorded, and saliva was collected on the baseline (D0) and after 28 days (D28) for microbiological analysis. Data from GBI and Colony Forming Units (CFU) (log10) were expressed as mean and standard deviation. RESULTS: The two groups reduced GBI significantly, with no difference in the intergroup analysis. In the intragroup analysis, it was observed that G2 (p < 0.001) had a significant reduction for Gram-negative bacteria, while there was significance (p < 0.001) had a significant reduction for Gram-negative bacteria, while there was significance (S. mutans bacteria, it was observed that only G2 had a statistically significant reduction (p < 0.001) had a significant reduction for Gram-negative bacteria, while there was significance (p < 0.001) had a significant reduction for Gram-negative bacteria, while there was significance (. CONCLUSIONS: Dentifrice containing BRP demonstrated better clinical and microbiological activity. Future studies are needed to better identify effects to establish the use of dentifrice containing propolis in biofilm control.

High Exploratory Phenotype Rats Exposed to Environmental Stressors Present Memory Deficits Accompanied by Immune-Inflammatory/Oxidative Alterations: Relevance to the Relationship Between Temperament and Mood Disorders.

Low-exploratory (LE) and high-exploratory (HE) rodents mimic human depressive and hyperthymic temperaments, respectively. Mood disorders (MD) may be developed by the exposure of these temperaments to environmental stress (ES). Psychiatric symptoms severity in MD patients is related to the magnitude of memory impairment. Thus, we aimed at studying the consequences of the exposure of LE and HE male Wistar rats, during periadolescence, to a combination of ES, namely, paradoxical sleep deprivation (PSD) and unpredictable stress (US), on anxiety-related behavior in the plus maze test, working (WM) and declarative memory (DM) performance. We also evaluated hippocampal immune-inflammatory/oxidative, as consequences of ES, and prevention of ES-induced alterations by the mood-stabilizing drugs, lithium and valproate. Medium exploratory (ME) control rats were used for comparisons with HE- and LE-control rats. We observed that HE-controls presented increased anxiolytic behavior that was significantly increased by ES exposure, whereas LE-controls presented increased anxiety-like behavior relative to ME-controls. Lithium and valproate prevented anxiolytic alterations in HE+ES rats. HE+ES- and LE+ES-rats presented WM and DM deficits. Valproate and lithium prevented WM deficits in LE-PSD+US rats. Lithium prevented DM impairment in HE+ES-rats. Hippocampal levels of reduced glutathione (GSH) increased four-fold in HE+ES-rats, being prevented by valproate and lithium. All groups of LE+ES-rats presented increased levels of GSH in relation to controls. Increments in lipid peroxidation in LE+ES- and HE+ES-rats were prevented by valproate in HE+ES-rats and by both drugs in LE+ES-rats. Nitrite levels were increased in HE+ES- and LE+ES-rats (five-fold increase), which was prevented by both drugs in LE+ES-rats. HE+ES-rats presented a two-fold increase in the inducible nitric oxide synthase (iNOS) expression that was prevented by lithium. HE+ES-rats showed increased hippocampal and plasma levels of interleukin (IL)-1ß and IL-4. Indoleamine 2, 3-dioxygenase 1 (IDO1) was increased in HE+ES- and LE+ES-rats, while tryptophan 2,3-dioxygenase (TDO2) was increased only in HE+ES-rats. Altogether, our results showed that LE- and HE-rats exposed to ES present distinct anxiety-related behavior and similar memory deficits. Furthermore, HE+ES-rats presented more brain and plasma inflammatory alterations that were partially prevented by the mood-stabilizing drugs. These alterations in HE+ES-rats may possibly be related to the development of mood symptoms.

Do Brazilian hospital pharmacists record, document, archive and disseminate their clinical practice?

An exploratory study was conducted to present the approach of Brazilian hospital pharmacists to registering, documenting, archiving and disseminating clinical practice. The data were collected using an electronic questionnaire (n=348). In fact, 97.41% of pharmacists record their clinical practice, out of which 64.01% (n=217) do in electronic form, mainly in private hospitals (p<0.000), in the central, southern and southeastern regions (p=0.040), and by professionals with 1-5 years of experience (p=0.001). The main software used is non-specific to clinical practice: an electronic spreadsheet (47.93%; n=104) and text editor (13.37%; n=29). The archiving of records is performed by 87.61% (n=297) of professionals, where 80.13% (n=238) do so in physical form; however, 77.31% (n=184) of these files are kept for less than the standard recommended time. Documentation in medical records is carried out by 55.17% (n=192) of pharmacists, increasing among those with 1-5 years of clinical practice (p=0.001), and dissemination is performed by 74.71% (n=260) of hospital pharmacists, with a lower frequency in public hospitals (p=0.012) and among professionals with fewer hours dedicated exclusively to clinical pharmacy (p=0.012). These results can undergird the revision of competency-based training programs of Brazilian clinical pharmacists to remain pharmacists as a valuable health team member
