RESUMO

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.

RESUMO

Stem cell-based approaches have the potential to address the organ shortage in transplantation. Whereas both embryonic stem cells and induced pluripotent stem cells have been utilized as cellular sources for differentiation and lineage specification, their relative ability to be recognized by immune effector cells is unclear. We determined the expression of immune recognition molecules on hepatocyte-like cells (HLC) generated from murine embryonic stem cells and induced pluripotent stem cells, compared to adult hepatocytes, and we evaluated the impact on recognition by natural killer (NK) cells. We report that HLC lack MHC class I expression, and that embryonic stem cell-derived HLC have higher expression of the NK cell activating ligands Rae1, H60, and Mult1 than induced pluripotent stem cell-derived HLC and adult hepatocytes. Moreover, the lack of MHC class I renders embryonic stem cell-derived HLC, and induced pluripotent stem cell-derived HLC, susceptible to killing by syngeneic and allogeneic NK cells. Both embryonic stem cell-derived HLC, and induced pluripotent stem cell-derived HLC, are killed by NK cells at higher levels than adult hepatocytes. Finally, we demonstrate that the NK cell activation receptor, NKG2D, plays a key role in NK cell cytotoxicity of embryonic stem cell-derived HLC, but not induced pluripotent stem cell-derived HLC.

RESUMO

OBJECTIVE: Several studies quantitatively described patients with Chronic Myeloid Leukaemia on active treatment with tyrosine kinase inhibitors, however there are few qualitative studies that focus their results on how to accompany patients in the course of the disease over time. The objective of this review is to find out what are the expectations, information needs and experiences that determine adherence to treatment with tyrosine kinase inhibitors in patients with Chronic Myeloid Leukaemia in qualitative research articles published in the scientific literature. METHODS: A systematic review of qualitative research articles published between 2003-2021 was carried out in PubMed/Medline, Web of Science and Embase databases. Main keywords used were: "Leukaemia, Myeloid" and "Qualitative Research". Articles on the acute phase or blast phase were excluded. RESULTS: 184 publications were located. After elimination of duplicates, 6 (3%) were included and 176 (97%) publications were excluded. Studies show that the illness is a turning point in patients' lives, and they develop their own strategies for managing the adverse effects. The factors that determine medication experiences with tyrosine kinase inhibitors should be addressed by implementing personalized strategies: this would result in early detection of problems, reinforce education at each stage and promote open discussion about complex causes underlying the treatment failure. CONCLUSIONS: This systematic review provides evidence that implementation personalized strategies must be done to adress the factors that determine the illness experience with Chronic Myeloid Leukaemia and receiving treatment with tyrosine kinase inhibitors.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Introduction: The experience of living with chronic pain allows for the appearance of changes in sleep patterns, mood, and stress levels. Objective: To describe the phases of stress and the quality of sleep in patients with chronic pain. Material and Methods: Cross-sectional study carried out at the pain clinic of the HUPES Complex, Salvador-Bahia. Data collection between March 2016 and November 2017. Instruments: Sociodemographic questionnaire, Numerical Pain Scale (EVN), Mini-Sleep Questionnaire (MSQ), and Stress Symptoms Inventory for LIPP adults (ISSL). Categorical variables were expressed by absolute and relative frequency and quantitative variables by means and standard deviation (SD). The comparison of categorical variables was performed using the chi-square test. Values of p<0.05 were considered statistically significant. Results: Mean age (standard deviation) of 50.0 (10) years, 89.6% of whom were female. Predominance of people with a partner, with religion, high school, and unemployed or removed by the INSS. They have severe sleep disorders, severe pain, and the presence of stress in the resistance phase. Most subjects reveal that they have improved with the treatment and have moderate self-esteem and personal satisfaction, despite the presence of anxious and depressive symptoms. Conclusion: Chronic pain has a very significant impact on life, increasing the level of stress, compromising and limiting daily activities, and showing more presence of anxious and depressive symptoms in people who suffer from chronic pain.

RESUMO

The study of medicinal plants for cancer treatment has gained attention due to an increasing incidence of cancer worldwide and antineoplastics-related undesirable secondary effects. Most of the natural products of medicinal plants that have been evaluated for cytotoxic activity, are derived from leaves, bark, roots and flowers. However, natural products derived from wood have demonstrated a cytotoxic effect with promising results. Moreover, some fractions and compounds have been isolated of wood in order to increase the effect. This review presents in vitro experimental evidence of cytotoxic effect of natural products from wood against cancer cell lines. It also provides considerations and recommendations to obtain herbal medicines over time.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: The objective of this study was to determine whether individuals with hip osteoarthritis who undergo THA have higher HRQOL scores than those awaiting the procedure; An additional aim was to investigate associated factors exerting an impact on HRQOL. MATERIALS AND METHODS: A cross-sectional study was conducted. Participants were divided into two groups: pre-THA and post-THA. Functional capacity was assessed using the Harris Hip Score, and HRQOL was measured using a validated and adapted version of the WOMAC questionnaire. A multivariate analysis of the WOMAC results was used to identify the main variables associated with HRQOL in both groups. RESULTS: The post-THA group had higher HRQOL scores (100.4 ± 88.5) than the pre-THA group (197.8 ± 54.1). The domains Pain (68.0 ± 19.0 versus 34.7 ± 30.8), Stiffness (61.2 ± 28.9 versus 29.9 ± 33.1), and Physical Activity (68.6 ± 16.1 versus 36.6 ± 30.2) also had higher scores in the post-THA group. Pain was the variable most frequently associated with the increase in post-THA HRQOL scores. Other variables such as occupation, time of diagnosis, joint function, and body weight also had an impact on the HRQOL of both groups. CONCLUSIONS: 1. Individuals who underwent THA had higher scores for HRQOL compared to those still awaiting the procedure. 2. Pain was the variable most strongly associated with quality of life.

Other variables such as occupation, time of diagnosis, joint function, and body weight also had an impact on the HRQOL of both groups. CONCLUSIONS: 1. Individuals who had undergone THA showed higher HRQOL scores in all domains when compared to those still awaiting the procedure, and pain reduction was the variable most strongly associated with the improvement in quality of life of those patients. 2. Occupation and mobility were associated with the Stiffness domain of QOL; Occupation also had a bearing on health-related quality of life as a whole. 3. Physical Activity of the WOMAC instrument was associated with time of diagnosis, patient's body weight, and function as assessed by the HHS.

RESUMO

Malaria is a serious health problem in the states of Córdoba and Antioquia, Northwestern Colombia, where 64.4% of total Colombian cases were reported in 2007. Because little entomological information is available in this region, the aim of this work was to identify the Anopheles species composition and natural infectivity of mosquitoes distributed in seven localities with highest malaria transmission. A total of 1,768 Anopheles mosquitoes were collected using human landing catches from March 2007-July 2008. Ten species were identified; overall, Anopheles nuneztovari s.l. was the most widespread (62%) and showed the highest average human biting rates. There were six other species of the Nyssorhynchus subgenus: Anopheles albimanus (11.6%), Anopheles darlingi (9.8%), Anopheles braziliensis (6.6%), Anopheles triannulatus s.l. (3.5%), Anopheles albitarsis s.l. and Anopheles oswaldoi s.l. at < 1%; and three of the Anopheles subgenus: Anopheles punctimacula, Anopheles pseudopunctipennis s.l. and Anopheles neomaculipalpusat < 1% each. Two species from Córdoba, An. nuneztovari and An. darlingi, were found to be naturally infected by Plasmodium vivax VK247, as determined by ELISA and confirmed by nested PCR. All species were active indoors and outdoors. These results provide basic information for targeted vector control strategies in these localities.

RESUMO

INTRODUCTION: Objective: to make a descriptive review about the influence of the dietary amino acids in gene expression. Materials and method: the bibliographic research included the following written sources: Scielo, PubMed, Medline, NCBI, Springer, Scopus, Science Direct and Elsevier, retrieved until May 2018 from critical reviews of scientific articles. One hundred and five records were found after the combination of key words. Fundamental selection criteria were taken into account (title, authors, summary and results) using Maeda's reasoned reduction and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) as a systematic review methodology. Conclusion: there are genes that are regulated in various stages including transcription, post-transcriptional processing, nuclear export and translation of mature mRNA. Amino acids can influence these processes through the activation of transcription factors. In terms of translation, amino acids can regulate protein synthesis through changes in eIF2B, phosphorylation of 4E-BP1 and S6 proteins. In addition, amino acids affect the regulation of the growth factor expression (insulin like grow factor: IGF-I) in humans.


INTRODUCCIÓN: Objetivo: realizar una revisión descriptiva sobre la influencia de aminoácidos (AA) provenientes de la dieta en la expresión génica. Materiales y método: la investigación bibliográfica incluyó las siguientes fuentes escritas: Scielo, PubMed, Medline, NCBI, Springer, Scopus, Science Direct y Elsevier, recuperadas hasta mayo de 2018, a partir de revisiones críticas de artículos científicos. Se encontraron 105 registros después de la combinación de palabras clave. Se tomaron en cuenta los criterios fundamentales de selección (título, autores, resumen y resultados) usando la reducción razonada de Maeda y PRISMA (elementos de informe preferidos para revisiones sistemáticas y metaanálisis) como metodología de revisión sistemática. Conclusiones: existen genes que se regulan en varias etapas: transcripción, procesado postranscripcional, exportación nuclear y traducción de los mRNA maduros. Los aminoácidos pueden tener influencia en estos procesos a través de la activación de factores de transcripción. En la traducción, los AA pueden regular la síntesis de proteínas mediante cambios en eIF2B, fosforilación de 4E-BP1 y de proteínas S6. Los AA tienen efecto en la regulación de la expresión de factores de crecimiento, como el factor de crecimiento análogo a la insulina IGF-I en el ser humano.

RESUMO

Objective: the aim of this study was to evaluate the quality of life between patients who have already undergone the TKA surgery and those who have not. Methodology: 118 patients [60 undergoing TKA (G1) and the remaining 58 awaiting the procedure (G2)] answered questions about QoL using the WOMAC and SF-36 protocols. The comparison was performed using the chi-square test and Student's t-test, with a significance level of 0.05. Results: with regard to clinical aspects, there was a higher level of pain in Group G2, as well as greater frequency in the use of medications, especially for pain relief. In the QoL evaluation, significant difference was observed in all the domains of the generic questionnaire SF-36 and in WOMAC, estando a capacidade functional do G2 reduzida e abaixo do nível observado nos pacientes do G1. Conclusion: patients with advanced knee arthrosis who underwent TKA, compared to those who did not undergo the procedure, had better quality of life in all domains assessed by both the general SF-36 questionnaire and the WOMAC questionnaire.


Objetivo: o objetivo deste estudo foi avaliar a qualidade de vida entre pacientes que já se submeteram à cirurgia de ATJ e aqueles que ainda não passaram pelo procedimento. Metodologia: 118 pacientes [60 submetidos à ATJ (G1) e os 58 restantes aguardando o procedimento (G2)] responderam perguntas sobre QV usando os protocolos WOMAC e SF-36. A comparação foi realizada usando o teste qui-quadrado e o teste t de Student, com um nível de significância de 0,05. Resultados: em relação aos aspectos clínicos, houve um maior nível de dor no Grupo G2, bem como maior frequência no uso de medicamentos, especialmente para alívio da dor. Na avaliação da QV, foi observada diferença significativa em todos os domínios do questionário genérico SF-36 e no WOMAC, estando a capacidade funcional do G2 reduzida e abaixo do nível observado nos pacientes do G1. Conclusão: pacientes com artrose avançada de joelho que se submeteram à ATJ, em comparação com aqueles que não passaram pelo procedimento, apresentaram melhor qualidade de vida em todos os domínios avaliados tanto pelo questionário geral SF-36 quanto pelo questionário WOMAC.

RESUMO

INTRODUCTION: Introduction: in several countries, there is an increasing trend of consumers and distributors of organic food. Objective: to identify consumer motivation, a socioeconomic profile and possible sociopolitical actions for the development of public policy by the consumers of organic products supplied by 12 alternative food distribution networks in Medellín and Eastern Antioquia. Methods: qualitative study with semi-structured interviews and participant and non-participant observation. Results: the main reason for organic food consumption is personal wellbeing, specifically health, followed by care for the environment and social welfare because such consumption contributes to improving the quality of life of poor producers (farmers and indigenous people). The consumption of these foods is also in some cases a form of resistance against the food industry, agroindustry and supermarkets; however, this social awareness does not imply that consumers commit themselves to sociopolitical actions transcending to the collective sphere. Conclusion: action by local governments is required to develop strategies that consolidate the transformative potential of consumer practices regarding organic products from alternative food networks.


INTRODUCCIÓN: Introducción: el incremento de consumidores y distribuidores de alimentos y productos orgánicos constituye una tendencia en varios países. Objetivo: establecer las motivaciones para el consumo, el perfil socioeconómico y las posibles acciones de carácter sociopolítico para la construcción de políticas públicas realizadas por los consumidores de productos orgánicos de las 12 redes de distribución alternativa de alimentos que existen en Medellín y el oriente antioqueño. Métodos: estudio cualitativo con entrevistas semiestructuradas y observación participante y no participante. Resultados: se halló que la principal razón de consumo es el bienestar individual, específicamente la salud, seguido del cuidado del medio ambiente y el bienestar social porque se contribuye a mejorar la calidad de vida de los productores pobres (campesinos e indígenas). Se encontró, además, que el consumo de estos alimentos, se hace en algunos casos como forma de resistencia frente a la industria de alimentos, la agroindustria y los supermercados. Sin embargo, esta conciencia social no implica que los consumidores se comprometan con acciones sociopolíticas para trascender a la esfera colectiva. Conclusión: se requiere una acción de los gobiernos locales para desarrollar estrategias que consoliden el potencial transformador de las prácticas de los consumidores de productos orgánicos de las redes alternativas de alimentos.

RESUMO

l estrés académico puede presentarse en estudiantes sometidos a diversas exigencias y requisitos universitarios, provocando diferentes reacciones de estrés, físicas, psicológicas y comportamentales, reduciendo su calidad de vida y provocando consecuencias como: depresión, tristeza, fatiga y dolores de cabeza, afectando su estado nutricional. Se investigó la relación entre ingesta de alimentos y estrés académico en estudiantes del cuarto semestre de la Licenciatura en Medicina de la Universidad Autónoma de Chihuahua. La población de estudio, dado el carácter piloto de la investigación, se realizó mediante muestreo simple, aleatorio, sin reemplazo, con un diseño mixto, descriptivo, comparativo y transversal, utilizándose el cálculo del tamaño muestral con un intervalo de confianza de 95%, resultando N=117; 51 hombres y 66 mujeres entre 19 y 43 años de la generación 2019, a quienes se les aplicó el inventario SISCO de estrés académico. Se encontró mayor frecuencia en situaciones que provocan preocupación y nerviosismo, sobrecarga de tareas y trabajo, inquietud, problemas de concentración, fatiga crónica y apatía. Las estrategias más utilizadas fueron: desarrollo de planes y ejecución de tareas y capacidad asertiva. El 92.2% (n=108) de la población encuestada manifestó preocupación y nerviosismo, resultando 52,1% (n=61) en mujeres y 40.1% (n=47) en hombres. El 38.5% (n=45) de las mujeres entre 21 y 43 años, muestran una mayor relación entre aumentar o reducir el consumo de alimentos en correspondencia con sentimientos de depresión y tristeza. El estrés académico, suele estar relacionado con diferentes manifestaciones psicológicas, físicas y conductuales, que pueden influir directamente en la población estudiantil, afectando gravemente sus hábitos alimenticios y nutricionales


Academic stress can occur in students subjected to various university demands and requirements, causing different, causing different physical, psychological and behavioral reactions. Reducing quality of life and causing consequences such as: depression, sadness, fatigue and headaches, affecting their nutritional status. The relationship between food intake and academic stress was investigated in students in the fourth semester of the Bachelor of Medicine at the Autonomous University of Chihuahua. The study population, given the pilot nature of the research, was carried out through simple, random sampling, without replacement, with a mixed, descriptive, comparative and transversal design, using the sample size calculation with a 95% confidence interval resulting in N=117; 51 men and 66 women between the ages of 19 and 43, from the 2019 generation, to whom the SISCO inventory of academic stress was applied. A greater frequency was found in situations that cause worry and nervousness, overload of tasks and work, restlessness, concentration problems, chronic fatigue and listlessness. The most used strategies were plan development and execution of tasks and assertive ability. 92.2% (n=108) of the surveyed population expressed concern and nervousness, in 52.1% (n=61) women and 40.1% (n=47) men. The 38.5% (n=45) of women between 21 and 43 years old show a greater relationship between increasing or reducing food consumption in correspondence with feelings of depression and sadness. Academic stress is usually related to different psychological, physical and behavioral manifestations, which can directly influence the student population, seriously affecting their eating and nutritional habits

RESUMO

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. Los factores que determinan la experiencia farmacoterapéutica con inhibidores tirosina cinasa deben abordarse mediante estrategias personalizadas: esto permitiría la detección temprana de problemas, reforzaría la educación en cada etapa y promovería la discusión abierta sobre las causas complejas que subyacen al fracaso del tratamiento.

Objective: Several studies quantitatively described patients with Chronic Myeloid Leukaemia on active treatment with tyrosine kinase inhibitors, however there are few qualitative studies that focus their results on how to accompany patients in the course of the disease over time. The objective of this review is to find out what are the expectations, information needs and experiences that determine adherence to treatment with tyrosine kinase inhibitors in patients with Chronic Myeloid Leukaemia in qualitative research articles published in the scientific literature.MethodsA systematic review of qualitative research articles published between 2003-2021 was carried out in PubMed/Medline, Web of Science and Embase databases. Main keywords used were: "Leukaemia, Myeloid" and "Qualitative Research". Articles on the acute phase or blast phase were excluded.Results184 publications were located. After elimination of duplicates, 6 (3%) were included and 176 (97%) publications were excluded. Studies show that the illness is a turning point in patients' lives, and they develop their own strategies for managing the adverse effects. The factors that determine medication experiences with tyrosine kinase inhibitors should be addressed by implementing personalized strategies: this would result in early detection of problems, reinforce education at each stage and promote open discussion about complex causes underlying the treatment failure.
