Effects of primary leachates of conventional and alternative plastics in Cyprinodon variegatus fish larvae: Endocrine disruption and toxicological responses.

The inclusion of hazardous substances in the formulation of plastics raises significant concerns, particularly, if those substances are released as primary leachates during plastic degradation and/or fragmentation. In this sense, the production of degradable plastics holding deleterious additives can increase the release of harmful substances into the environment. Additionally, the effects of primary leachates of "eco-friendly" materials remain unexplored. To address this, we performed exposures to primary leachates of alternative polymers, and commercial bags to verify possible responses associated with endocrine disruption and/or activation of the detoxification pathway in larvae of the marine fish model Cyprinodon variegatus. The chemical characterization evidenced a great number of additives in the formulation of the materials analyzed in this study. Those include, except for the PLA sample, relevant levels of the hazardous phthalates DEHP and DiBP. Regarding the effects on marine fish larvae, exposure to leachates from alternative polymers (10 g/L) PHB and PHBV produced remarkable mortality (100%). While the exposure to bag leachates of all tested materials (1 and 10 g/L) produced alterations in biomarkers for steroidogenic and detoxification pathways. To a lesser extent (10 g/L), three materials produced significant alterations in estrogenic biomarkers (Home-compostable bag 1, LDPE and Recycled PE bags). Although the alterations in gene expression were not directly correlated to the amount of DEHP or DiBP, we can conclude that primary leachates of "eco-friendly" bags are harmful to marine vertebrates.

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. 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.

Evaluating the alterations of the estrogen-responsive genes in Cyprinodon variegatus larvae for biomonitoring the impacts of estrogenic endocrine disruptors (EEDs).

Currently, endocrine disruptors (EDs) can be found in all the environmental compartments. To understand the effects of estrogenic EDs (EEDs), adults of Cyprinodon variegatus have been classically used as a marine model. However, it is during development that exposure to contaminants may generate permanent consequences. Thus, the aim of this study was to verify the effects produced by acute exposure to 17α-ethinylestradiol (EE2) in C. variegatus larvae. Quantitative PCR (qPCR) results revealed the induction of vtg and zp gene expression on exposure to 1000 ng/L EE2 and the induction of vtgc, zp2, zp3 and cyp19a2, and inhibition of vtgab, wap and cyp1a1 on exposure to 100 ng/L EE2. Lower concentrations inhibited the gene expression of vtgab and wap (50 ng/L), cyp1a1 (25 ng/L) and zp2 (12.5 ng/L). These alterations in gene expression allow us to affirm that larvae of C. variegatus are an efficient and sensitive model for biomonitoring EEDs.

Impact of a pharmaceutical intervention on influenza vaccination in patients receiving treatment with biological medicines.

OBJECTIVE: The aims of this study were twofold - to determine the impact of a health education intervention led by a hospital pharmacy department on influenza vaccination take-up in patients diagnosed with immune-mediated diseases. Patients were receiving treatment with biological medicines. Secondly, to compare those rates with the vaccination percentages of another hospital pharmacy with similar characteristics in which no educational intervention was conducted. METHODS: This was a retrospective cohort study of adult patients with immune-mediated diseases receiving treatment with biological medicines. The medicines were dispensed by the hospital pharmacy departments of two hospitals between 1 January 2019 and 31 December 2020. In Cohort A (intervention group), a health education strategy was implemented with regards to influenza vaccination. Cohort B acted as a control group. The influenza vaccination rates obtained in both cohorts during 2019 and 2020 were compared. RESULT: A total of 355 patients took part in the study - 148 (41.7%) in Cohort A and 207 (58.3%) in Cohort B. The hospital pharmacy department in Cohort A implemented a health education strategy after which the vaccination percentage during the 2020 campaign increased by 38 patients (45.7%), compared with a 10 patient (5.8%) increase in Cohort B (p<0.001). CONCLUSIONS: The health intervention by the pharmacy department had a positive impact. This included an opportunity to improve vaccination take-up and is a strategy to consider when implementing a vaccination programme. Health education is a fundamental objective of healthcare. In our case it led to an increase in vaccination and had a positive impact on public health. It also provides opportunities for pharmacists to work in a multidisciplinary way with other healthcare professionals.
