Tackling potentially inappropriate prescriptions in older adults: development of deprescribing criteria by consensus from experts in Colombia, Argentina, and Spain.

BACKGROUND: Potentially inappropriate medication use is prevalent among older adults in primary care, leading to increased morbidity, adverse drug reactions, hospitalizations, and mortality. This study aimed to develop and validate a tool for identifying PIMs in older adults within the primary care setting. The tool is composed of a list of criteria and was created based on consensus among experts from three Spanish-speaking countries, including two from Latin America. METHODS: A literature review was conducted to identify existing tools, and prescription patterns were evaluated in a cohort of 36,111 older adults. An electronic Delphi method, consisting of two rounds, was used to reach a formal expert consensus. The panel included 18 experts from Spain, Colombia, and Argentina. The content validity index, validity of each content item, and Kappa Fleiss statistical measure were used to establish reliability. RESULTS: Round one did not yield a consensus, but a definitive consensus was reached in round two. The resulting tool consisted of a list of 5 general recommendations per disease, along with 33 criteria related to potential problems, recommendations, and alternative therapeutic options. The overall content validity of the tool was 0.87, with a Kappa value of 0.69 (95% CI 0.64-0.73; Substantial). CONCLUSIONS: The developed criteria provide a novel list that allows for a comprehensive approach to pharmacotherapy in older adults, intending to reduce inappropriate medication use, ineffective treatments, prophylactic therapies, and treatments with an unfavorable risk-benefit ratio for the given condition. Further studies are necessary to evaluate the impact of these criteria on health outcomes.

A prototype of a low-cost eyelid cleaning foaming solution for symptom management in patients with chronic blepharitis: An I-optimal mixture experimental design / Un prototipo de solución espumante de bajo costo para la limpieza de párpados y el manejo de síntomas en pacientes con blefaritis crónica: un diseño de mezcla I-óptimo

SUMMARY Blepharitis is a common chronic eye condition that causes eyelid inflammation, leading to inflamed, irritated, sticky and itchy eyelids and flaking of the skin. For its treatment, patients often need indefinite use of an eyelid cleaning solution which usually cost more than 20 USD per 80 ml bottle and lasts, on average, one month. For those patients unable to afford the treatment, physicians recommend the use of a do it yourself (DIY) solution. However, the efficacy of DIY eyelid solutions might fluctuate according to the type of blepharitis present in the patient and inadequate pH stabilization of the solution might promote additional itchiness, irritation, and dryness of the skin and eyes. Thus, we propose an optimized DIY solution prototype for symptom management in patients with chronic blepharitis. The formulation contains a significant ratio of tea tree oil and resulted in suitable pH and foam expansion values. The low cost and ease of preparation of the designed formulation make it an affordable, effective alternative in the treatment of chronic blepharitis.

RESUMEN La blefaritis crónica es una condición ocular que causa inflamación en los párpados, dando como resultado párpados irritados, pegadizos y descamación de la piel. Pacientes con esta condición necesitan usualmente de la aplicación de una solución de limpieza de párpados que cuesta en promedio 20 USD por cada 80 ml de solución y tiene un rendimiento de un mes. Para aquellos pacientes incapaces de costear el tratamiento, los médicos recomiendan el uso de soluciones hazlo tú mismo (DIY en inglés). Sin embargo, la eficacia de estas en el tratamiento de la condición puede fluctuar de acuerdo con el tipo de blefaritis presente. Adicionalmente, una inadecuada estabilización del pH de la solución puede promover una mayor irritación, resequedad y picazón en la piel y en los ojos. Por lo tanto, en este trabajo proponemos un prototipo experimental de solución DIY para el manejo sintomático de pacientes con blefaritis crónica. La formulación contiene una proporción significativa de aceite de árbol de té y posee un pH adecuado y alta producción de espuma para su correcta aplicación en la piel. El bajo costo y facilidad de preparación hacen de ella una alternativa efectiva y asequible en el tratamiento de la blefaritis crónica.

An International Perspective of Transition of Neurological Disease: The Latin American and the Caribbean Region.

There are roughly 600 million people in the Latin America and the Caribbean region, of whom approximately 36% are living at or below the poverty line. According to this, neurologic injury disorders disproportionately affect this population, which faces not only most risk factors, but also has less developed health systems to deal with illness recovery. Further, most of the risk factors can be attributed to classic preventable cardiovascular risk factors, although there are important differences in demographics, socioeconomic status, and injury mechanisms that may influence the patient's outcome.

[Adverse drug reactions in neonates hospitalized in neonatal intensive care units in Barranquilla, Colombia].

INTRODUCTION: The appearance of adverse drug reactions in neonates is an important issue due to the lack of drug safety data. OBJECTIVE: To identify the behavior of adverse drug reactions (ADR) in hospitalized neonates at two intensive care units in Barranquilla, Colombia. MATERIALS AND METHODS: We conducted a cross-sectional prospective descriptive study based on patientcentered intensive pharmacosurveillance. We followed up and monitored the appearance of ADRs for six months. We used Naranjo's algorithm to assess causality, modified Hartwig and Siegel assessment scale to establish severity and Schumock and Thornton criteria to determine ADR preventability. RESULTS: We detected 123 adverse drug reactions in 78 neonates of the 284 monitored. The cumulative incidence of ADRs was 27.4% (78/284); incidence density was 30.60 ADRs per 1,000 patients/day (78/2,549). The most affected organ system was the digestive (33.6%). Systemic anti-infective drugs were the most involved pharmacological group. Most of the ADRs were mild (58.5%), 83% were classified as probable, 16.2% as possible and 0.8% as definite. CONCLUSIONS: ADR incidence was high in newborns, and it increased in preterm infants (less than 38 weeks of age).

Adverse drug reactions in hospitalized Colombian children.

INTRODUCTION: The occurrence of adverse drug reactions is an important issue due to the lack of drug safety data in children. OBJECTIVE: To describe the Adverse Drug Reactions in inpatient children under 6 years of age in two general pediatrics wards located in Barranquilla, Colombia. METHODS: A prospective cohort study based on intensive pharmacovigilance was conducted during six months in order to monitor the emergence of Adverse Drug Reactions in inpatients children under 6 years of age with at least one medication prescribed. The study was conducted in two pediatric wards of two hospitals located in Barranquilla, Colombia. Naranjo´s Algorithm was used to evaluate imputability, the modified Hartwig and Siegel assessment scale to establish severity and the Schumock and Thornton criteria to determine preventability. RESULTS: Of a total of 772 monitored patients, 156 Adverse Drug Reactions were detected on 147 children. The cumulative incidence of Adverse Drug Reactions was 19.0% (147/772); the incidence density was 37.6 Adverse Drug Reactions per 1,000 patients-days (147/3,913). The frequency was higher in children under 2 years of age (12.7%). Emergence of Adverse Drug Reactions was higher in male patients (RR= 1.66; 95% CI= 1.22-2.22, p= 0.001) and in those who used systemic antibiotics (RR= 1.82; 95% CI= 1.17-2.82, p= 0.005). CONCLUSIONS: Adverse Drug Reactions are common among hospitalized children and represent an additional burden of morbidity and risk, particularly in those who used several medicines, including antibiotics.
