Abstract In the Brazilian Health System (SUS), drugs covered by the Specialized Pharmaceutical Scheme (CEAF) receive federal funding and can be procured either centrally (Group 1A) or by individual states (Federal Units - UF) (Group 1B). Unlike other countries where national procurement prices are negotiated centrally by the government, public procurement in Brazil follows a public auction procedure, potentially resulting in varying purchase prices. To facilitate price comparisons, it is a legal requirement to register public acquisitions in the Health Prices Registry (BPS). This study aimed to assess the variability in the procurement prices for Group 1B drugs across the 27 Brazilian states during 2021. Data on the acquisitions of Group 1B drugs by the 27 Health Secretariats were obtained from the BPS. Drugs with no reported reimbursement prices as of December 2021 were excluded from the analysis. The total reimbursement amount for each state was sourced from the SUS Ambulatory Information System. The findings revealed significant variability in drug procurement prices both across and within states. The study underscored a potential disparity in CEAF access, favoring wealthier states (those with larger populations and higher economic status) by securing lower drug prices.

This study aims to develop, validate, and evaluate machine learning algorithms for predicting the diagnosis of coronavirus disease (COVID-19), human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), pulmonary tuberculosis (TB), and HIV/TB co-infection. We also investigated potential biomarkers associated with the diagnosis. Data from biochemical and hematological tests of infected and controls were collected in a single general hospital, totalizing 6,418 patients. The discriminant analysis by partial least squares (PLS-DA) model had the highest performance in predicting the diagnosis of COVID-19, HIV/AIDS, TB, and HIV/TB co-infection with an accuracy of 94, 97, 95, and 96%, respectively. The biomarkers calcium, lactate dehydrogenase, red blood cells (RBC), white blood cells, neutrophils, basophils, eosinophils, hemoglobin, and hematocrit were associated with COVID-19. HIV infection was associated with mean corpuscular volume, platelets, neutrophils, and mean platelet volume. Red blood cell distribution width and urea were associated with infection by Mycobacterium tuberculosis. The following biomarkers were associated with HIV/TB co-infection: lymphocytes, RBC, hematocrit, hemoglobin, aspartate transaminase, alanine transaminase, and glycemia. The PLS-DA model can optimize COVID-19, HIV/AIDS, TB, and HIV/TB co-infection diagnostics. Some biomarkers were potential diagnostic indicators and could be evaluated during the screening of these diseases. develop validate COVID19, COVID19 COVID 19 , (COVID-19) virusacquired virus acquired HIVAIDS HIV/AIDS AIDS (HIV/AIDS) TB (TB) HIVTB coinfection. coinfection co infection. hospital 6418 6 418 6,41 patients PLSDA PLS DA (PLS-DA 19, COVID-19 94 97 95 96 96% respectively calcium dehydrogenase RBC (RBC) neutrophils basophils eosinophils hemoglobin COVID19. 19. volume platelets lymphocytes transaminase glycemia diagnostics diseases COVID1 1 (COVID-19 (HIV/AIDS (TB 641 41 6,4 COVID-1 9 (RBC (COVID-1 64 4 6, COVID- (COVID- (COVID

Abstract The Specialized Component of Pharmaceutical Services (CEAF) is a crucial strategy for accessing medicines through the Brazilian Public Health System, holding the highest budgetary impact on outpatient pharmaceutical care. This study aimed to assess the association of socioeconomic factors with access to CEAF drugs in municipalities throughout Paraná from 2010 to 2019. It utilized a retrospective, observational, cross-sectional approach, evaluating dispensed medication units, medication expenditure, and average unit cost. Analyses were performed to identify a correlation between the use of CEAF drugs and socioeconomic indicators. In these 10 years, the number of dispensed units practically quadrupled, and the expenditure on these drugs doubled, from BRL 214 million to BRL 476 million. The Index of Paraná Institute for Economic and Social Development of Municipal Performance (IPDM) showed a greater association with the use of CEAF drugs, and no correlation was observed between gross domestic product (GDP) per capita and the municipal population. Overall, the IPDM index that includes income, education, and health are socioeconomic factors that influence the utilization of CEAF drugs. These findings emphasize the need for health education among users and adjustment of public policies to mitigate inequalities in the CEAF drug access for the citizens of Paraná.

Abstract Topical treatments for skin conditions offer significant benefits, yet understanding the rheological characteristics of semi-solid formulations is crucial, as they directly influence treatment adherence through their applicability. Ideally, these formulations should maintain their placement at the application site and facilitate easy spreading without requiring excessive force, particularly on painful lesions. In this study, a Python-based tool was developed to assess the rheological behavior of formulations, with a gel-cream serving as a model to demonstrate its applicability. The model formulation was created by emulsifying an oily phase, including blackcurrant oil, with an aqueous phase containing xanthan gum as a gelling agent. Rheological parameters were determined using a rotational viscometer. The prepared gel-cream exhibited pseudoplastic behavior, with viscosity decreasing as rotation speed increased. The Python tool was utilized to extract information about the rheological properties of the samples. Upon applying the data to various mathematical models, it was confirmed that the formulations displayed pseudoplasticity, with the Ostwald-de-Waele model demonstrating the best fit for all evaluated formulations. This pseudoplastic behavior was further confirmed by calculating the flow index (ɳ), which was found to be lower than 1. Open-source tools are gaining popularity across various industries due to their transparency, collaborative nature, and cost-effectiveness. They enable users to enhance product properties, explore therapeutic targets, facilitate efficient collaboration, develop customized software, create predictive models, and ensure regulatory compliance. Our study offers a precise solution for determining the rheological behavior of semi-solid formulations while mitigating human estimation errors. However, it's important to note that proficiency in programming is required to utilize this tool effectively. benefits semisolid semi solid crucial applicability Ideally force lesions Pythonbased based gelcream gel cream oil agent viscometer increased samples models pseudoplasticity OstwalddeWaele Ostwald de Waele ɳ, ɳ , (ɳ) 1 Opensource Open source transparency nature costeffectiveness. costeffectiveness cost effectiveness. effectiveness cost-effectiveness targets collaboration software compliance errors However s effectively (ɳ

Naltrexone (NTX) and bupropion (BUP) are used in combination in clinical practice for obesity; however, the existing analytical methods for this drug combination are not sustainable. This work aims to develop an analytical method that is faster, easier and less expensive compared with high performance liquid chromatography (HPLC) and involves green technology without solvents to quantify BUP and NTX in combination. The objective was to validate a method using mid-infrared (MIR) spectroscopy associated with multivariate calibration and chemometrics to simultaneously measure NTX and BUP in a pharmaceutical capsule form. The models were developed using MIR spectroscopy with diffuse reflectance, with interval partial least squares (iPLS) variable selection. The working range selected to optimize the model was from 1885.8 to 1585.4 cm-1. The chosen model was obtained with partial least squares (PLS2) and with data pre-processed by first derivative Savitzky-Golay smoothing followed by mean centering, using four latent variables, providing a root mean square error of prediction of 1.8 mg g-1 for NTX and 6.42 mg g-1 for BUP. The method was validated according to current international standards. In conclusion, the methods developed in the MIR region provided statistically similar results to the validated chromatographic method for commercial pharmaceutical formulations.

Abstract A stability-indicating HPLC-DAD method was developed and validated for the simultaneous determination of dasabuvir and its degradation products in the pharmaceutical formulation. The proposed method utilized a Symmetry® C18 (4.6 x 75 mm, 3.5 µm) column, and the mobile phase consisted of an isocratic elution of formic acid (0.1%) and acetonitrile (55:45, v/v), at a flow of 1 mL min-1; analytes were detected at 244 nm. Dasabuvir was submitted to different stress degradation conditions, such as acidic, alkaline, neutral, thermal, oxidative and photolytic, and the structural elucidation of degradation products was performed using LC-QToF-MS/MS. The HPLC-DAD stability-indicating method was validated for selectivity, linearity, limit of detection and quantification, accuracy, precision and robustness, according to ICH guidelines. Dasabuvir produced two degradation products (DP1 and DP2) from the alkaline stress conditions, which were characterized in negative ion mode. Dasabuvir was linear in the range 9.78 to 136.92 µg mL-1, and DP and DP were linear in the range 2.9 to 20.2 µg mL-1 and 1.3 to 14.9 µg mL-1, respectively. The 1 2 recovery ranged between 99.16 and 100.86%, while precision ranged from 1.02 to 2.89%. As the method can effectively separate the dasabuvir from its degradation products and quantitate them, it may be employed as a stability-indicating method for the pharmaceutical formulation. stabilityindicating stability indicating HPLCDAD HPLC DAD formulation Symmetry C C1 4.6 46 4 6 (4. 7 mm 35 3 5 3. µm column 0.1% 01 0 (0.1% 5545, 5545 55 45, 45 (55:45 v/v, vv v/v , v v/v) min1 min min-1 24 nm conditions acidic neutral thermal photolytic LCQToFMS/MS.

To identify natural bioactive compounds (NBCs) as potential inhibitors of spike (S1) by means of in silico assays. NBCs with previously proven biological in vitro activity were obtained from the ZINC database and analyzed through virtual screening and molecular docking to identify those with higher affinity to the spike protein. Eight machine learning models were used to validate the results: Principal Component Analysis (PCA), Artificial Neural Network (ANN), Support Vector Machine (SVM), k-Nearest Neighbors (KNN), Partial Least Squares-Discriminant Analysis (PLS-DA), Gradient Boosted Tree Discriminant Analysis (XGBoostDA), Soft Independent Modelling of Class Analogies (SIMCA) and Logistic Regression Discriminate Analysis (LREG). Selected NBCs were submitted to drug-likeness prediction using Lipinski’s and Veber’s rule of five. A prediction of pharmacokinetic parameters and toxicity was also performed (ADMET). Antivirals currently used for COVID-19 (remdesivir and molnupiravir) were used as a comparator. A total of 170,906 compounds were analyzed. Of these, 34 showed greater affinity with the S1 (affinity energy < -7 kcal mol-1). Most of these compounds belonged to the class of coumarins (benzopyrones), presenting a benzene ring fused to a lactone (group of heterosides). The PLS-DA model was able to reproduce the results of the virtual screening and molecular docking (accuracy of 97.0%). Of the 34 compounds, only NBC5 (feselol), NBC14, NBC15 and NBC27 had better results in ADMET predictions. These had similar binding affinity to S1 when compared to remdesivir and molnupirvir. Feselol and three other NBCs were the most promising candidates for treating COVID-19. In vitro and in vivo studies are needed to confirm these findings.

ABSTRACT Introduction: Oral anticoagulants are the treatment of choice for diverse types of coagulation disorders. Warfarin is widely used by the Brazilian population, possibly due to its lower cost than other oral anticoagulants. However, it has a high risk of serious adverse effects if used incorrectly. The Anticoagulation Knowledge Tool (AKT) can assess a patient’s knowledge about her/his oral anticoagulant therapy and can assist health professionals in identifying patients with difficulties in adherence. This study aimed to translate, culturally adapt, and validate the AKT into Brazilian Portuguese. Methods: After a standard forward-backward procedure to translate the AKT into Brazilian Portuguese (AKT-Br), a version of the instrument was applied in three groups (patients, pharmacists, and the general population). The reliability of the AKT-Br was tested using an internal consistency measure and test-retest. The validity of the instrument was confirmed with data from the contrasted groups. All statistical analyses were performed with RStudio. Results: The median scores obtained with the AKT-Br were 29.0, 17.0, and 7.5 for pharmacists, patients, and the general population, respectively (maximum score of 35 points). There was moderate internal consistency for the instrument and test-retest reliability was satisfactory. Analysis of variance for validity of the groups revealed a significant relationship between the total score and the evaluated groups. Conclusion: The ATK-Br is a reliable and valid tool to assess knowledge about oral anticoagulants. AKT-Br can be used in clinical practice as an auxiliary tool to improve patient care through personalised educational interventions.

Abstract The delivery of clinical pharmacy services has been growing in Brazilian community pharmacies, and it is necessary to have a comprehensive understanding of the topic. This scoping review aimed to provide an overview of Brazilian studies about clinical pharmacy services in community pharmacies. Original research articles, with no restriction of time, study design, or patient’s health condition, were included. Searches were conducted in PubMed, Scopus, Web of Science, Scielo, and Lilacs. Two reviewers conducted the screening, full-text reading, and data extraction independently. ROB and ROBINS-I were used for the assessment of quality. Charts and tables were built to summarise the data. Seventy-two articles were included. A diversity of study designs, number of participants, terms used, and outcomes was found. São Paulo and Sergipe States had the highest number of studies (n=10). Pharmacists’ interventions were not fully reported in 65% of studies, and most studies presented an unclear risk of bias. Studies were very diverse, impairing the comparisons between the results and hindering their reproducibility. This review suggests using guidelines and checklists for better structuration of pharmacists’ interventions as well as reporting results and measuring fidelity in future research. pharmacies topic time design patients patient s condition included PubMed Scopus Science Scielo Lilacs screening fulltext full text reading independently ROBINSI ROBINS I quality Seventytwo Seventy two designs participants found n=10. n10 n n=10 . 10 (n=10) Pharmacists 65 bias diverse reproducibility pharmacists n1 n=1 1 (n=10 6 n= (n=1 (n= (n

Abstract Pharmacists acting in pharmacies and drugstores stores are some of the most accessible healthcare providers and the last to intervene before the patient takes their medicine. This puts the pharmacist in a position of authority that should be harnessed for the benefit of health. Thus, this professional is strategic for performing pharmacovigilance. Our objective of this study was to interrogate the practice of pharmacists in relation to pharmacovigilance activities, and to identify difficulties and possible stimuli for the improvement these activities in pharmacies and drugstores. The information was collected through an online questionnaire via Survey Monkey®. The data were analyzed statistically using SPSS software. Responses were received from 5174 pharmacists: mostly young women within five years of graduation and experience in pharmaceutical retail. 81% of them reported having identified suspected substandard medicines, but only 16% used the Brazilian notification system Notivisa. More than 85% of pharmacists agreed with the importance of pharmacovigilance and the recognition of reporting services as part of pharmacist duties and pharmaceutical care. The main barriers to making notifications were the lack of access and knowledge about Notivisa. Pharmacists agreed that simplifying the system would be a stimulus for notifications, and requested more feedback from notifications, as well as material and courses to understand the notification process. Pharmacists have important data to feed into pharmacovigilance systems, recognize their responsibilities and are willing to contribute, but still demonstrate low compliance. Simplification of the system and training on it are likely to increase notifications.

Abstract The objective of this study is to validate the specific questionnaire for Hepatitis B HBQOL (Hepatitis B Quality of Life Instrument, version 1.0) for the Brazilian version, in addition to testing its applicability in patients with hepatitis B under treatment and comparing the quality of life between patients using first-line drugs (tenofovir and entecavir). For the validation, the back-translation technique was used in a sample of 47 patients. Factor analysis was performed between the items in each domain of the questionnaire and the internal consistency was calculated using Cronbach's α coefficient. In assessing the applicability of the validated questionnaire, interviews were carried out with 124 patients. Sociodemographic and treatment data were collected to characterize the sample and perform correlation analyzes. The results demonstrate that the Brazilian version of the questionnaire was successfully validated. In the analysis carried out among the 124 patients, the domains psychological well-being and stigma obtained the highest scores in quality of life and the lowest level of education conferred better results in these two domains. The comparison between tenofovir and entecavir showed no significant difference in patients' quality of life. The use of this validated instrument can make therapeutic decisions more rational.

Resumo A artrite reumatóide (AR) está entre as doenças autoimunes e inflamatórias crônicas mais prevalentes no mundo. O objetivo deste estudo foi estabelecer uma estimativa conjunta da prevalência da AR na América do Sul por meio de uma meta-análise dos estudos epidemiológicos disponíveis. Buscas sistemáticas nas bases de dados PubMed, Lilacs, SciELO, Scopus e Web of Science (atualizado em maio de 2019) foram seguidas por uma busca sistemática na literatura cinzenta para identificar artigos e relatórios de pesquisa originais, publicados após 2000, fornecendo dados de prevalência de AR em qualquer país da América do Sul. Foi realizada uma meta-análise da proporção de dados agrupados ponderados, com heterogeneidade entre experimentos avaliada pelo índice relativo de inconsistência. Análises de sensibilidade e de subgrupos também foram realizadas. Foram incluídos um total de 25 artigos, representando 27 estudos de base populacional. A prevalência agrupada de AR resultou em 0,48% com 591.981 casos em uma população de 114.537.812 indivíduos (I2=99%). Brasil e Colômbia apresentaram as menores taxas de prevalência de AR 0,22% e 0,24%, respectivamente. A prevalência da AR na população indígena foi maior 1,45%, e estudos pelo método COPCORD relataram também as maiores taxas 1,07%.

Abstract Rheumatoid arthritis (RA) is among the most prevalent chronic autoimmune and inflammatory diseases worldwide. The aim of this study was to establish a pooled estimate of the RA prevalence in South America by means of a meta-analysis of the available epidemiologic studies. Systematic searches in PubMed, Lilacs, SciELO, Scopus, and Web of Science databases (updated May 2019) were done followed by a systematic grey literature search to identify original research articles and reports, published after 2000, providing data of RA prevalence in any South American country. Proportion meta-analysis of weighted pooled was performed, with between-trial heterogeneity assessed by the inconsistency relative index. Sensitivity analyses and sub-group analyses were also done. A total of 25 articles, representing 27 population-based studies were included. Pooled prevalence of RA resulted in 0.48% with 591,981 cases in a population of 114,537,812 individuals (I2=99%). Brazil and Colombia presented the lowest rates of RA prevalence 0.22%, and 0.24%, respectively. RA prevalence in indigenous population was higher 1.45%, and studies using COPCORD method reported also the highest rates 1.07%.
