Effectiveness of teaching and evaluation methods of clinical competencies for pharmacy: A systematic review.

BACKGROUND: This review aimed to analyze the effectiveness of the teaching and assessment methodologies used to develop fundamental clinical skills in pharmacist who are training in patient care. METHODS: SCOPUS, EMBASE, ERIC, and PubMed were searched for original studies that featured randomized controlled trials as the study design published until March 2024. The search and extraction process followed PRISMA Guidelines. RESULTS: The database search resulted in 2954 articles, of which 14 met the inclusion criteria. Four studies developed and tested interactive web-based software as the teaching methodologies. Eight studies applied simulation to their teaching and/or evaluation strategies. Two articles used high fidelity simulation, and the remaining studies used standardized patients associated with other teaching and evaluation techniques. The simulation methodologies were more effective than the conventional ones in three studies. In the other studies, the interventions were as effective or better than the control, albeit there no meaningful differences between the methods. In the studies that focused on the assessment methods, immediate feedback was preferred by students over delayed feedback. Additionally, the tested assessment tool, General Level Framework, proposed a pragmatic assessment from which the individual's training needs were identified. CONCLUSION: Few studies involved the objective quantification of learning beyond pre- and post-intervention knowledge tests. Proper assessment in pharmaceutical education requires expansion beyond the administration of student satisfaction, self-efficacy research tools, and knowledge assessments, and should encompass an examination of clinical performance and critical thinking.

Early Results of Fenestrated and Branched Endovascular Repair of Complex Aortic Aneurysms with a Custom-made National Device Available in the Brazilian Public Health System.

BACKGROUND: Multicenter studies conducted in developed countries demonstrated that custom-made devices are safe, effective, and durable for treating complex abdominal aneurysms. However, the situation in developing countries, such as Brazil, is different. Funding and time to have the endoprosthesis delivered are the major concerns. In order to overcome these conditions, high-volume Brazilian university hospitals started gaining experience with a custom-made device produced in the country. OBJECTIVE: The present study aimed to describe the practice of 2 tertiary centers and report the early results of fenestrated and branched endovascular repair of complex aortic aneurysms with a custom-made national device available in the Brazilian public health system. METHODS: Retrospective analysis of all consecutive patients that underwent fenestrated and branched endovascular aneurysm repair (F/BEVAR) of complex aortic aneurysms using custom-made manufactured endoprosthesis in 2 tertiary centers from January 2020 to July 2022. RESULTS: Thirteen cases were included (10 male, mean age 69 ± 9 years). 70% were complex abdominal aneurysms, and 30% were type II, III, and IV thoracoabdominal aneurysms (mean aneurysm diameter 69.2 ± 8.12 mm). F/BEVAR included 33 visceral arteries. The Apolo® device was used in all cases. Technical success was achieved in 12 out of 13 patients (92.3%). Thirty-day major adverse events included one death (7.7%), 5 acute renal failure (38.4%), 2 spinal cord ischemia (15.4%). The 1-year survival rate was 92.3%. CONCLUSIONS: Fenestrated and branched endovascular repair of complex aortic aneurysms with the custom-made Apolo® device has proven safe and effective in high-volume tertiary centers in the Brazilian public health system. Considering the complexity of the cases, the early patency of vessels and low initial mortality support this device continuation and expansion to treat complex aortic aneurysms in a developing country.

Performance, interpersonal relationships and professional satisfaction: determinants to support pharmaceutical reengineering.

Professionalism represents the ethical contract that binds professionals and society. Its technical aspects, such as the professional practice model, form the foundation for attitudinal and behavioral characteristics, including the fiduciary relationship between pharmacists and patients. Despite significant interest in the topic, contextualizing professionalism proves to be a challenging endeavor, relying on collaboration among formal leaders, academics, and practitioners in the field. Consequently, defining, understanding, teaching, and evaluating pharmaceutical professionalism contribute to shape societal perceptions and the understanding of pharmacists and students, who may occasionally struggle to grasp the underlying rationale behind professional practices. Moreover, contextualizing professionalism entails addressing various challenges, such as fostering support for professionalism and its adaptation, which encompasses pharmacists' performance across diverse clinical services, their interpersonal interactions with patients, families, communities, and fellow healthcare professionals, as well as personal job satisfaction amidst obstacles as job insecurity, ethical dilemmas, and compromised autonomy.

Perceptions of Children and Caregivers Regarding Asthma and Its Pharmacotherapy: A Qualitative Study.

Asthma, when untreated, may lead to serious implications, especially in the pediatric population. Understanding the perceptions and needs of children and their caregivers may optimize asthma management. This study was aimed to analyze the perceptions of children and their caregivers regarding asthma and its pharmacotherapy. This is a qualitative study using 2 focus groups. We use the Bardin's content analysis. Three researchers made data cross-validation. As for results, the first focus group comprised 7 children who had uncontrolled asthma. The second group comprised 7 caregivers who were the children's mothers. Four categories emerged: living with asthma, impact of asthma, medications, and health care. Asthma and its pharmacotherapy significantly affect the daily activities of children and mothers. Thus, understand feelings and experiences of patients and caregivers, in addition to educational and welcoming interventions for families in asthma management may be carried out by health care professionals to minimize the damage caused by this disease.

Analysis of Variance Combined with Optimized Gradient Boosting Machines for Enhanced Load Recognition in Home Energy Management Systems.

Load recognition remains not comprehensively explored in Home Energy Management Systems (HEMSs). There are gaps in current approaches to load recognition, such as enhancing appliance identification and increasing the overall performance of the load-recognition system through more robust models. To address this issue, we propose a novel approach based on the Analysis of Variance (ANOVA) F-test combined with SelectKBest and gradient-boosting machines (GBMs) for load recognition. The proposed approach improves the feature selection and consequently aids inter-class separability. Further, we optimized GBM models, such as the histogram-based gradient-boosting machine (HistGBM), light gradient-boosting machine (LightGBM), and XGBoost (extreme gradient boosting), to create a more reliable load-recognition system. Our findings reveal that the ANOVA-GBM approach achieves greater efficiency in training time, even when compared to Principal Component Analysis (PCA) and a higher number of features. ANOVA-XGBoost is approximately 4.31 times faster than PCA-XGBoost, ANOVA-LightGBM is about 5.15 times faster than PCA-LightGBM, and ANOVA-HistGBM is 2.27 times faster than PCA-HistGBM. The general performance results expose the impact on the overall performance of the load-recognition system. Some of the key results show that the ANOVA-LightGBM pair reached 96.42% accuracy, 96.27% F1, and a Kappa index of 0.9404; the ANOVA-HistGBM combination achieved 96.64% accuracy, 96.48% F1, and a Kappa index of 0.9434; and the ANOVA-XGBoost pair attained 96.75% accuracy, 96.64% F1, and a Kappa index of 0.9452; such findings overcome rival methods from the literature. In addition, the accuracy gain of the proposed approach is prominent when compared straight to its competitors. The higher accuracy gains were 13.09, 13.31, and 13.42 percentage points (pp) for the pairs ANOVA-LightGBM, ANOVA-HistGBM, and ANOVA-XGBoost, respectively. These significant improvements highlight the effectiveness and refinement of the proposed approach.

"Opportunities and responsibilities": how do pharmacists assess their professionalism?

INTRODUCTION: Professionalism is fundamental to the existence of professions. In pharmacy, interest in this theme improved with events that examined the resocialization of pharmacists in care. With this, evaluating professionalism can help the operationalization of the theme and, consequently, the development of strategies for pharmacy consolidation before its challenges. Therefore, this study aimed to evaluate the professionalism of Brazilian pharmacists. METHODS: To meet the objective, a cross-sectional study was conducted between March 2022 and August 2023. Data were collected using the Brazilian version of the "Modification of Hall's Professionalism Scale for Use with Pharmacists". The scale has 39 items grouped into the domains: autonomy, vocation, professional council, self-regulation, continuing education, and altruism. Data were analyzed using descriptive statistics and an ANOVA analysis of variance with post-hoc Hochberg or Games-Howell tests with Bootstrapping was conducted to verify differences between groups. RESULTS: 600 pharmacists participated in this study. The majority (69%) was female and carried out their professional activities in community pharmacies (50%). Professionalism scores ranged between 14 and 29 points, with an average of 22.8 points. Pharmacists working in outpatient clinics had higher scores in most factors, namely, altruism, continuing education, professional council, vocation, and autonomy. This indicates that the inclination of pharmacists to occupy areas focused on care can be significant to assess professionalism. CONCLUSIONS: The data obtained indicate that pharmacists working in outpatient clinics had higher professionalism scores compared to others. This corroborates the worldwide trend experienced by pharmacy in recent decades, which is the execution of increasingly patient-centered practice models.

Parkinson's disease and levodopa-induced dyskinesias: a quantitative analysis through 99mTc-TRODAT-1 SPECT imaging of the brain.

Objective: To compare the dopamine transporter (DAT) density with other risk factors for L-DOPA-induced dyskinesia (LID) in patients with Parkinson's disease (PD), with and without LID. Materials and Methods: We evaluated 67 subjects: 44 patients with idiopathic PD of varying degrees of severity (PD group), and 23 healthy age-matched volunteers (control group). Among the 44 patients in the PD group, 29 were male and the following means were recorded at baseline: age, 59 ± 7 years; disease duration, 10 ± 6 years; Hoehn and Yahr (H&Y) stage, 2.16 ± 0.65; and Unified Parkinson's Disease Rating Scale part III (UPDRS III) score, 29.74 ± 17.79. All subjects underwent 99mTc-TRODAT-1 SPECT. We also calculated specific uptake ratios or binding potentials in the striatum. Results: The DAT density in the ipsilateral and contralateral striata was lower in the PD group. The variables disease duration, L-DOPA dosage, doses per day, L-DOPA effect duration time, H&Y stage, and UPDRS III score explained the occurrence of LID. The DAT density in the ipsilateral striatum, contralateral striatum, and caudate nucleus was lower in the patients with LID than in those without. Conclusion: Our findings suggest that presynaptic dopaminergic denervation is associated with LID in individuals with PD.

Objetivo: Comparar a densidade do transportador de dopamina (DAT) com outros fatores de risco para discinesia induzida pela L-DOPA em pacientes com doença de Parkinson, com e sem discinesias. Materiais e Métodos: Sessenta e sete sujeitos, 23 voluntários saudáveis e 44 pacientes pareados por idade com diferentes graus de gravidade da doença de Parkinson idiopática (29 homens; idade média ± desvio-padrão (DP), 59 ± 7 anos; duração média ± DP dos sintomas, 10 ± 6 anos; H&Y: média ± DP, 2,16 ± 0,65; UPDRS III: média ± DP, 29,74 ± 17,79). Todos os sujeitos realizaram SPECT cerebral com 99mTc-TRODAT-1. Além disso, foram calculadas as taxas de captação específica ou potenciais de ligação no estriado. Resultados: A densidade de DAT do estriado ipsilateral ou contralateral foi menor no grupo doença de Parkinson. As variáveis duração da doença, dosagem de L-DOPA, doses por dia, tempo de duração do efeito da L-DOPA, H&Y e UPDRS III explicaram a ocorrência de discinesia. Adicionalmente, pacientes com discinesia exibiram menor densidade de DAT no estriado ipsilateral ou contralateral e no núcleo caudado do que os pacientes sem discinesia. Conclusão: O presente estudo sugere que a denervação dopaminérgica pré-sináptica na doença de Parkinson está associada ao desenvolvimento de discinesia induzida pela L-DOPA.

Uterine Artery Embolization Versus Hysterectomy in Postpartum Hemorrhage: A Systematic Review With Meta-Analysis.

PURPOSE: The objective of this study is to perform a meta-analysis comparing the effectiveness of uterine artery embolization (UAE) versus peripartum hysterectomy for acute refractory postpartum hemorrhage (PPH) control. MATERIALS AND METHODS: We systematically searched 6 medical databases for studies comparing UAE and hysterectomy in PPH. Outcomes examined were mortality, hospitalization duration (HD) in days, and red blood cells (RBC) units utilization. Statistical analysis used RevMan 5.1.7 and random-effects models. Odds ratios (OR) and mean differences (MDs) with 95% confidence intervals (CIs) were used for dichotomous and continuous outcomes, respectively. RESULTS: We included 833 patients from 4 cohort studies, with 583 (70%) undergoing UAE. The UAE population required fewer RBC units (MD: -7.39; 95% CI: -14.73 to -0.04; p=0.05) and had shorter HD (MD: -3.22; 95% CI: -5.42 to -1.02; p=0.004). Lower mortality rates were noted for UAE in the pooled analysis, but no statistical significance. Uterine artery embolization demonstrated lower procedural complications (16.45% vs. 28.8%), in which UAE had less ureter and bladder lesions (OR: 0.05; 95% CI: 0.01-0.38; p=0.004 and OR: 0.02; 95% CI: 0.00-0.15; p<0.001, respectively). Only 35 (6%) required conversion to hysterectomy, while 27 (4.6%) underwent re-embolization with 100% bleeding control. Uterine artery embolization did not hinder fertility, with normal menstruation restored in 19 patients with postoligomenorrhea. CONCLUSION: Uterine artery embolization for the control of PPH is associated with lower use of RBC units and HD, but similar rates of mortality are noted when compared to hysterectomy. These results associated with uterine preservation could support its importance for refractory PPH management. CLINICAL IMPACT: Uterine Artery Embolization is associated with a shorter hospitalization duration and reduced use of red blood cell units when compared with hysterectomy in refractory postpartum hemorrhage. Although demonstrating similar mortality rates, these findings, together with fertility preservation, support the method incorporation as a valuable option in obstetric services.

OBJECTIVE: to understand the construct of autonomy based on perceptions of formal leaders associated with professional organizations. METHODS: A qualitative study was conducted through interviews with key informants. The data obtained were submitted to content analysis. RESULTS: Perceptions about the autonomy in pharmaceutical practice were categorized according to strengths, weaknesses, opportunities, and threats to this construct. CONCLUSION: The findings allowed us to understand the autonomy of pharmaceutical practice in Brazil, generate hypotheses about the future of Pharmacy, and build strategies to maintain its occupational status.

Load Recognition in Home Energy Management Systems Based on Neighborhood Components Analysis and Regularized Extreme Learning Machine.

Efficient energy management in residential environments is a constant challenge, in which Home Energy Management Systems (HEMS) play an essential role in optimizing consumption. Load recognition allows the identification of active appliances, providing robustness to the HEMS. The precise identification of household appliances is an area not completely explored. Gaps like improving classification performance through techniques dedicated to separability between classes and models that achieve enhanced reliability remain open. This work improves several aspects of load recognition in HEMS applications. In this research, we adopt Neighborhood Component Analysis (NCA) to extract relevant characteristics from the data, seeking the separability between classes. We also employ the Regularized Extreme Learning Machine (RELM) to identify household appliances. This pioneering approach achieves performance improvements, presenting higher accuracy and weighted F1-Score values-97.24% and 97.14%, respectively-surpassing state-of-the-art methods and enhanced reliability according to the Kappa index, i.e., 0.9388, outperforming competing classifiers. Such evidence highlights the promising potential of Machine Learning (ML) techniques, specifically NCA and RELM, to contribute to load recognition and energy management in residential environments.

The academic formation challenges: what does retail expect from higher education institutions in pharmacy?

BACKGROUND: The drug retail represents the main area of activity for pharmacists worldwide. In Brazil, this sector is responsible for employing around 80% of professionals. Before this reality, the academic training of pharmacists requires specialized skills and knowledge so they can fulfill their tasks. In this sector, considering the influence of managers and mentors on the model of pharmaceutical practice, their perceptions about the demands of the market can help discussions related to the training of pharmacists. AIM: To analyze the academic training of pharmacists for the drug retail market from the perspective of managers and mentors. METHOD: This is a qualitative study conducted with managers and mentors of the drug retail market. A semi-structured interview guide was prepared and applied to the intentionally selected participants. The study was approved by the Research Ethics Committee under the number 4,169,752. The interviews were conducted through videoconference by an experienced researcher. The data obtained were analyzed using Bardin's analysis technique, following the steps of categorical thematic content analysis using the ATLAS.ti software. RESULTS: 19 interviews were carried out. Among the reports, the interviewees highlighted the importance of retail in the employability of pharmacists, as well as inconsistency in the academic training for this sector, originating the following categories: curriculum reform to include the market demands, follow-up and career plan, training for entrepreneurship and sales, practical application of knowledge, and encouragement of experience. CONCLUSION: Pharmaceutical academic training is linked to several challenges, whether organizational, structural, or budgetary. To overcome these challenges, it is necessary to unite the interested parties in the formulation and implementation of a strategy for the professionalization of pharmacists, considering their social role in patient care, aligned with the company's sustainability, so that both coexist.

Sodium nitroprusside enhances stepping test performance and increases medium spiny neurons responsiveness to cortical inputs in a rat model of Levodopa-induced dyskinesias.

Levodopa (L-DOPA) is the classical gold standard treatment for Parkinson's disease. However, its chronic administration can lead to the development of L-DOPA-induced dyskinesias (LIDs). Dysregulation of the nitric oxide-cyclic guanosine monophosphate pathway in striatal networks has been linked to deficits in corticostriatal transmission in LIDs. This study investigated the effects of the nitric oxide (NO) donor sodium nitroprusside (SNP) on behavioural and electrophysiological outcomes in sham-operated and 6-hydroxydopamine-lesioned rats chronically treated with vehicle or L-DOPA, respectively. In sham-operated animals, systemic administration of SNP increased the spike probability of putative striatal medium spiny neurons (MSNs) in response to electrical stimulation of the primary motor cortex. In 6-hydroxydopamine-lesioned animals, SNP improved the stepping test performance without exacerbating abnormal involuntary movements. Additionally, SNP significantly increased the responsiveness of putative striatal MSNs in the dyskinetic striatum. These findings highlight the critical role of the NO signalling pathway in facilitating the responsiveness of striatal MSNs in both the intact and dyskinetic striata. The study suggests that SNP has the potential to enhance L-DOPA's effects in the stepping test without exacerbating abnormal involuntary movements, thereby offering new possibilities for optimizing Parkinson's disease therapy. In conclusion, this study highlights the involvement of the NO signalling pathway in the pathophysiology of LIDs.

Perceptions of formal pharmacy leadership on the social role of the profession and its historical evolution: A qualitative study.

Background: In recent years, pharmaceutical professionalism has been questioned due to the social role of pharmacy, which is ambiguous in the literature. This raises questions about the purpose of the profession among pharmacists, despite the efforts of their professional organizations and formal leaders to consolidate the occupational status of the profession. Objective: To understand the social role of pharmacy in Brazil through its historical evolution based on the perceptions of formal leaders of the profession. Methods: A qualitative study was conducted between July 2020 and February 2021 with pharmacists who held leadership positions in formal and professional pharmacy organizations in Brazil. The data obtained from the interviews were submitted to content analysis. Results: A total of 17 pharmacists participated in this study. The data analyzed presented perceptions about the social role of the pharmaceutical profession in Brazil, which promotes access to health through different means. These include the manager pharmacist, who facilitates access to public health policies; the caring pharmacist, who promotes health education and the rational use of medicines; and the technologist pharmacist, who researches, develops, and promotes access to safe and cost-effective medicines. The interviewees also discussed the evolution of this social role based on influential factors such as legislation, clinical movement, pharmaceutical education, labor market, behaviors, and attitudes of pharmacists. Conclusion: In this study, pharmaceutical professionalism was conceptualized based on its social role, which should be centered on the patient. Understanding such issues is part of the evolutionary purpose of the profession in Brazil and should be encouraged in the behaviors and attitudes of pharmacists despite the challenges faced by the profession.

Alamandine attenuates oxidative stress in the right carotid following transverse aortic constriction in mice.

OBJECTIVE: Pressure overload can result in significant changes to the structure of blood vessels, a process known as vascular remodeling. High levels of tension can cause vascular inflammation, fibrosis, and structural alterations to the vascular wall. Prior research from our team has demonstrated that the oral administration of alamandine can promote vasculoprotective effects in mice aorta that have undergone transverse aortic constriction (TAC). Furthermore, changes in local hemodynamics can affect the right and left carotid arteries differently after TAC. Thus, in this study, we aimed to assess the effects of alamandine treatment on right carotid remodeling and the expression of oxidative stress-related substances induced by TAC. METHODS AND RESULTS: Male C57BL/6 mice were categorized into three groups: Sham, TAC, and TAC treated with alamandine (TAC+ALA). Alamandine treatment was administered orally by gavage (30 µg/kg/day), starting three days before the surgery, and continuing for a period of fourteen days. Morphometric analysis of hematoxylin and eosin-stained sections revealed that TAC induced hypertrophic and positive remodeling in the right carotid artery. Picrosirius Red staining also demonstrated an increase in total collagen deposition in the right carotid artery due to TAC-induced vascular changes. Alamandine treatment effectively prevented the increase in reactive oxygen species production and depletion of nitric oxide levels, which were induced by TAC. Finally, alamandine treatment was also shown to prevent the increased expression of nuclear factor erythroid 2-related factor 2 and 3-nitrotyrosine that were induced by TAC. CONCLUSION: Our results suggest that alamandine can effectively attenuate pathophysiological stress in the right carotid artery of animals subjected to TAC.

Teaching Strategies for Professional Identity Education in Pharmacy: A Scoping Review.

OBJECTIVES: To characterize which strategies of professional identity formation and professionalism are being used in Pharmacy. FINDINGS: We gathered 5004 articles from 5 databases with the descriptors "pharmacy" "professionalism," "professional identity" and their synonyms. The professional identity is a set of values and behaviors common among professionals. Professionalism is the moral compass of these values, used as a strategy to own social authenticity. After excluding duplicate texts, analyzing titles, abstracts, and full articles, 17 studies met the inclusion criteria and presented strategies for the formation of professional identity and professionalism in pharmacy students. We did not find studies with pharmacists. The quality of reports was assessed using 2 instruments recommended by the literature. All studies were conducted from 2007 onwards, and the United States is the country with the most publications. The identified strategies consisted of extracurricular activities, thematic courses, lectures, and counseling sessions and did not follow standards of theoretical reference, method, execution, duration, and effectiveness of evaluation. SUMMARY: The interest of Pharmacy about professional identity and professionalism has grown substantially in recent years. Teaching strategies are essential alternatives to improve professionalism, reinforce its importance, and acknowledge its heterogeneity and differences. For that, they must be in line with the aims of the profession in society. This review highlights the need to develop standardized and reproducible teaching strategies to guarantee the effectiveness of students' professional socialization during graduation, as well as to instruct professionals to deal with the changes in the profession, increasing the influence of Pharmacy in society.

Challenges of Congenital Heart Surgery in Brazil: It is Time to Designate Pediatric Congenital Heart Surgery Subspecialty

ABSTRACT Congenital heart disease (CHD) affects eight to ten out of every 1,000 births, resulting in approximately 23,057 new cases in Brazil in 2022. About one in four children with CHD requires surgery or other procedures in the first year of life, and it is expected that approximately 81% of these children with CHD will survive until at least 35 years of age. Professionals choosing to specialize in CHD surgery face numerous challenges, not only related to mastering surgical techniques and the complexity of the diseases but also to the lack of recognition by medical societies as a separate subspecialty. Furthermore, families face difficulties when access to services capable of providing treatment for these children. To address these challenges, it is essential to have specialized hospitals, qualified professionals, updated technologies, sustainable industry, appropriate financing, quality assessment systems, and knowledge generation. The path to excellence involves specialization across all involved parties. As we reflect on the importance of Pediatric Cardiovascular Surgery and Congenital Heart Diseases establishing themselves as a subspecialty of Cardiovascular Surgery, it is essential to look beyond our borders to countries like the United States of America and United Kingdom, where this evolution is already a reality. This autonomy has led to significant advancements in research, education, and patient care outcomes, establishing a care model. By following this path in Brazil, we not only align our practice with the highest international standards but also demonstrate our maturity and the ability to meet the specific needs of patients with CHD and those with acquired childhood heart disease.

Aortic Thrombosis Associated with Three Types of COVID-19 Vaccine.

Aortic thrombosis has been studied little in patients with COVID-19 and an association has recently been reported with the vaccine for this disease. The aim of the present study is to report five cases of aortic thrombosis at our institution within a three-month period associated with the COVID-19 vaccine. Five cases of aortic thrombosis were evaluated-three women and two men aged 29, 49, 51, 60, and 79 years. Four thrombi involved the thoracic aortic and one involved the abdominal aorta, with embolisms found in the kidneys, spleen, liver, upper limbs, and lower limbs. Embolectomy was performed on the limbs, and anticoagulant therapy was performed for the abdominal arteries. The patients recovered well and anticoagulant therapy was maintained. Aortic thrombosis is uncommon but was associated with the AstraZeneca vaccine in this case series.
