[Translated article] Medication experience and clinical interventions in patients receiving pharmaceutical care: A scoping review of pharmaceutical care practice.

OBJECTIVE: Analyze scientific literature on qualitative research that studies the medication experience-MedExp-and related pharmaceutical interventions that bring changes in patients' health. Through the content analysis of this scoping review, we intend to: (1) understand how pharmacists analyze the MedExp of their patients who receive Comprehensive Medication Management CMM and (2) explain which categories they establish and how they explain the individual, psychological, and cultural dimensions of MedExp. METHODS: The scoping review followed recommendations from PRISMA Extension for Scoping Reviews. Medline (Pubmed), SCOPUS, Web of Science, and Psycinfo were used to identify research on MedExp from patients attended by pharmacists; and that they comply with quality standards, Standards for Reporting Qualitative Research. Articles published in English and Spanish were included. RESULTS: 395 qualitative investigations were identified, 344 were excluded. In total, 19 investigations met the inclusion criteria. Agreement between reviewers, kappa index 0.923, 95% CI (0.836-1.010). The units of analysis of the patients' speeches were related to how they were progressing in their medications and how it was built through MedExp, the influence it has on the experience of becoming ill, the connection with socioeconomic aspects, and beliefs. Based on MedExp, the pharmacists raised cultural proposals, support networks, health policies, and provide education and information about medication and disease. Additionally, characteristics of the interventions were identified, such as a dialogic model, therapeutic relationship, shared decision-making, comprehensive approach, and referrals to other professionals. CONCLUSIONS: The MedExp is an extensive concept, which encompasses people's life experience who use medications based on their individual, psychological, and social qualities. This MedExp is corporal, intentional, intersubjective, and relational, expanding to the collective because it implies beliefs, culture, ethics, and the socioeconomic and political reality of each person located in their context.

Necesidades y experiencia farmacoterapéutica de los pacientes con leucemia mieloide crónica tratados con inhibidores de la tirosina cinasa: revisión sistemática / Medication experience and patient’s related needs in chronic myeloid leukemia treated with tyrosine kinase inhibitors: Systematic review

Objetivo: diversas investigaciones cuantitativas generan evidencia sobre los pacientes con leucemia mieloide crónica y el tratamiento activo con inhibidores tirosina cinasa, pero son escasas las investigaciones cualitativas que orienten sus resultados a cómo acompañar a los pacientes a lo largo de su enfermedad. El objetivo es conocer las expectativas, las necesidades de información y las experiencias condicionantes al usar inhibidores tirosina cinasa en los pacientes con leucemia mieloide crónica en los estudios cualitativos publicados en la literatura científica.Métodosse revisaron sistemáticamente investigaciones cualitativas publicadas entre 2003 y 2021 en Pubmed/Medline, Web of Science y Embase de pacientes con leucemia mieloide crónica tratados con inhibidores tirosina cinasa. Las palabras clave fueron «Leukemia, Myeloid» y «Qualitative Research». Se excluyeron artículos sobre la fase aguda o blástica.Resultadosse localizaron 184 publicaciones. Eliminando los duplicados, se incluyeron 6 (3%) y excluyeron 176 (97%). Los estudios muestran la enfermedad como inflexión en la vida de los pacientes, quienes desarrollan sus propias estrategias para controlar los efectos adversos.

Case report: Serotoninergic and cholinergic syndromes induced by self-medication.

Self-medication is a part of the self-care practices carried out by the elderly in their environment. The aim of this case report is to show how the self-medication of fluoxetine and dimenhydrinate in an older adult can induce serotoninergic and cholinergic syndromes, showing symptoms such as nausea, tachycardia, tremor, loss of appetite, memory loss, decreased vision, falls, and increased urination. An older adult who has been diagnosed with arterial hypertension, dyslipidemia, diabetes mellitus, and a recent diagnosis of essential thrombosis is the subject of this case report. After the analysis of the case, cessation of fluoxetine was recommended to avoid withdrawal symptoms, therefore decreasing the need for dimenhydrinate and the medicines used for dyspepsia. After the recommendation, the patient showed an improvement in the symptoms. Finally, the comprehensive evaluation process of the medication in the Medicines Optimization Unit achieved the detection of the problem and improved the patient's health condition.

Cytotoxic effect and induction of apoptosis in human cervical cancer cells by a wood extract from Prosopis laevigata.

Cervical cancer ranks fourth in incidence among women worldwide. Cisplatin is currently the first-line drug of treatment for cervical cancer; however, it causes serious adverse effects. Therefore, it is crucial to explore natural products for cervical cancer treatment. Prosopis laevigata is a medicinal plant frequently used for ophthalmological and gastrointestinal infections. In this study, we used the MTT cell viability assay to evaluate the cytotoxic effect of a wood extract from Prosopis laevigata (Extract T7) in SiHa, HeLa, Ca Ski, and C-33 A cancer cell lines. Phosphatidylserine translocation and cell cycle evaluations were performed to determine the mechanism of cellular death. The extract's safety was evaluated using the Ames test with Salmonella typhimurium strains, in vivo acute toxicity assay, and repeated dose toxicity assay in mice. We also identified phenolic compounds of Extract T7 through liquid chromatography/mass spectrometry. Naringin, catechin, and eriodictyol demonstrated a higher concentration in Extract T7. Additionally, Extract T7 exhibited a cytotoxic effect against cervical cancer cells, where C-33 A was the most sensitive (IC50= 22.58 ± 1.10 µg/mL and 14.26 ± 1.11 µg/mL at 24 h and 48 h respectively). Extract T7 induced death by apoptosis and cell cycle arrest in the G2 phase in C-33 A. Extract T7 was not mutagenic. No toxicological effects were observed during acute toxicity and repeated dose toxicity for 28 days. Therefore, further evaluations of Extract T7 should be conducted to identify the complete mechanism of action for potential anti-tumoral activity and safety before conducting studies in animal models.

Bioinformatics Insights on the Physicochemical Properties of SCN5A Mutant Proteins Associated with the Brugada Syndrome.

BACKGROUND: The Brugada syndrome (BrS) is a heart rhythm condition that is commonly associated with a strong predisposition for sudden cardiac death. Malignant ventricular arrhythmias could occur secondary to the dysfunction of the cardiac sodium voltage-gated Na(v)1.5 channel (SCN5A). OBJECTIVE: This study aimed to perform a multiparametric computational analysis of the physicochemical properties of SCN5A mutants associated with BrS using a set of bioinformatics tools. METHODS: In-house algorithms were calibrated to calculate, in a double-blind test, the Polarity Index Method (PIM) profile and protein intrinsic disorder predisposition (PIDP) profile of each sequence, and computer programs specialized in the genomic analysis were used. RESULTS: Specific regularities in the charge/polarity and PIDP profile of the SCN5A mutant proteins enabled the re-creation of the taxonomy, allowing us to propose a bioinformatics method that takes advantage of the PIM profile to identify this group of proteins from their sequence. CONCLUSION: Bioinformatics programs could reproduce characteristic PIM and PIDP profiles of the BrS-related SCN5A mutant proteins. This information can contribute to a better understanding of these altered proteins.

Bioinformatics-based Characterization of the Sequence Variability of Zika Virus Polyprotein and Envelope Protein (E).

Background: Zika virus, which is widely spread and infects humans through the bites of Aedes albopictus and Aedes aegypti female mosquitoes, represents a serious global health issue. Objective: The objective of the present study is to computationally characterize Zika virus polyproteins (UniProt Name: PRO_0000443018 [residues 1-3423], PRO_0000445659 [residues 1-3423] and PRO_0000435828 [residues 1-3419]) and their envelope proteins using their physico-chemical properties. Methods: To achieve this, the Polarity Index Method (PIM) profile and the Protein Intrinsic Disorder Predisposition (PIDP) profile of 3 main groups of proteins were evaluated: structural proteins extracted from specific Databases, Zika virus polyproteins, and their envelope proteins (E) extracted from UniProt Database. Once the PIM profile of the Zika virus envelope proteins (E) was obtained and since the Zika virus polyproteins were also identified with this profile, the proteins defined as "reviewed proteins" extracted from the UniProt Database were searched for the similar PIM profile. Finally, the difference between the PIM profiles of the Zika virus polyproteins and their envelope proteins (E) was tested using 2 non-parametric statistical tests. Results: It was found and tested that the PIM profile is an efficient discriminant that allows obtaining a "computational fingerprint" of each Zika virus polyprotein from its envelope protein (E). Conclusion: PIM profile represents a computational tool, which can be used to effectively discover Zika virus polyproteins from Databases, from their envelope proteins (E) sequences.

Ethanolic extract of Lippia graveolens stem reduce biochemical markers in a murine model with metabolic syndrome.

Metabolic Syndrome (MetS) is a risk to develop metabolic-chronic degenerative disease, it is important to find natural alternatives to help decrease the risk. Mexican oregano has a traditional use in Mexican food, moreover, has pharmacologic effects that can help to reduce risk the metabolic syndrome. The aim of this work was to determine the effect of Mexican oregano ethanolic extract in metabolic syndrome in murine model. Ethanolic extract of Mexican oregano (Lippia graveolens) stem (Ext) had a favorable effect on biochemical markers in a murine model of MetS, induced by injection of monosodium glutamate (MSG). From newborn female mice, two groups were formed: control and the MSG groups, which received a dosage of 2 mg/kg of MSG via subcutaneous injection at the second and fourth postnatal day (PD 2,4), and 4 mg/kg at the PD 6, 8, 10 to induce obesity. On week 13, a part of the MSG group received Ext (group MSG + Ext) at 300 mg/kg, administered orally daily from week 13 to week 18. The results indicated that ethanolic extract of Lippia graveolens stem decreases the percentage of body fat, waist circumference, and body weight gain as well as cholesterol, serum triglyceride concentrations and systolic and diastolic pressure. Insulin and leptin hormone values showed a significant effect with the Ext administration. However, hepatic lipoperoxidation levels of MSG and MSG + Ext groups did not show any statistically significant differences between them, both being higher than the control group. Taking in consideration the results obtained in this study, it is concluded that the administration of Ext had a beneficial effect in the murine model with MetS. This is the first study demonstrating the potential of the polar fraction Lippia graveolens stem in MetS.
