RESUMEN

INTRODUCTION: Intensive Care Units (ICUs) pose challenges in managing critically-ill patients with polypharmacy, potentially leading to Adverse Drug Reactions (ADRs), particularly in the elderly. OBJECTIVE: To evaluate whether the severity and clinical prognosis scores used in ICUs correlate with the prediction of ADRs in aged patients admitted to an ICU. METHODS: A cohort study was conducted in a Brazilian University Hospital ICU. APACHE II and SAPS 3 assessed clinical prognosis, while GerontoNet ADR Risk Score and BADRI evaluated ADR risk at ICU admission. Severity of the patients' clinical conditions was evaluated daily based on the SOFA score. Adverse Drug Reaction (ADR) screening was performed daily through the identification of ADR triggers. RESULTS: 1295 triggers were identified (median 30 per patient, IQR = 28), with 15 suspected ADRs. No correlation was observed between patient severity and ADRs at admission (p=0.26), during hospitalization (p=0.91), or at follow-up (p=0.77). There was also no association between death and ADRs (p=0.28) or worse prognosis and ADRs (p>0.05). Higher BADRI scores correlated with more ADRs (p=0.001). CONCLUSIONS: The data suggest that employing the severity and clinical prognosis scores used in Intensive Care Units is not sufficient to direct active pharmacovigilance efforts, which are therefore indicated for critically ill patients.

RESUMEN

INTRODUCTION: Older patients are more susceptible to medication use, and physiological changes resulting from aging and organic dysfunctions presented by critically ill patients may alter the pharmacokinetic or pharmacodynamic behavior. Thus, critically ill older people present greater vulnerability to the occurrence of pharmacotherapeutic problems. OBJECTIVE: To evaluate pharmacotherapy and the development of potential adverse drug reactions (ADRs) in older patients admitted to an intensive care unit (ICU). METHOD: A cohort study was conducted in an ICU for adults of a Brazilian University Hospital during a 12-month period. The patients' pharmacotherapy was evaluated daily, considering the occurrence of ADRs and drug-drug interactions (DDIs), the use of potentially inappropriate medications (PIMs) for older people, and the pharmacotherapy anticholinergic burden (ACB). A trigger tool was used for active search of ADRs, with subsequent causality evaluation. PIM use was evaluated by means of the Beers criteria and the STOPP/START criteria. The ABC scale was employed to estimate ACB. The Micromedex® and Drugs.com® medication databases were employed to evaluate the DDIs. RESULTS: The sample of this study consisted of 41 patients, with a mean age of 66.8 years old (±5.2). The 22 triggers used assisted in identifying 15 potential ADRs, and 26.8% of the patients developed them. The mean estimated ACB score was 3.0 (±1.8), and the patients used 3.1 (±1.4) and 3.3 (±1.6) PIMs according to the Beers and the STOPP criteria, respectively. A total of 672 DDIs were identified, with a mean of 16.8 (±9.5) DDIs/patient during ICU hospitalization. Our findings show an association between occurrence of ADRs in the ICU and polypharmacy (p=.03) and DDIs (p=.007), corroborating efforts for rational medication use as a preventive strategy. CONCLUSIONS: Using tools to evaluate the pharmacotherapy for older people in intensive care can assist in the recognition and prevention of pharmacotherapeutic problems, with emphasis on the identification of ADRs through the observation of triggers and subsequent causality analysis.

RESUMEN

INTRODUCTION: Pharmacogenetics evaluates how genetic variations influence drug responses. Nowadays, genetic tests have advanced, becoming more affordable, and its integration is supported by stronger clinical evidence. Guidelines such as those from CPIC (Clinical Pharmacogenetics Implementation Consortium) and resources like PharmGKB facilitate genotype-based prescribing; and organizations like the FDA promote genetic testing before initiating certain medications. Preventive pharmacogenetic panels seem promising, but further research on biomarkers and diverse populations is needed. The aim of this review is to analyze recent evidence on the genotype-drug response relationship to examine how the genetic profile of patients influences the clinical response to treatments, and analyze the areas of research that need further study to advance towards a genetic-based precision medicine. MATERIALS AND METHODS: A systematic search was conducted on PubMed to identify articles investigating the genotype-drug response relationship. The search strategy included terms such as "pharmacogenetics", "personalized treatment", "precision medicine", "dose adjustment", "individualized dosing", "clinical routine" and "clinical practice." Clinical trials, observational studies, and meta-analyses published in English or Spanish between 2013 and 2023 were included. The initial search resulted in a total of 136 articles for analysis. RESULTS: 49 articles were included for the final analysis following review by two investigators. A relationship between genetic polymorphisms and drug response or toxicity was found for drugs such as opioids, GLP-1 agonists, tacrolimus, oral anticoagulants, antineoplastics, atypical antipsychotics, efavirenz, clopidogrel, lamotrigine, anti-TNF-α agents, voriconazole, antidepressants, or statins. However, for drugs like metformin, quetiapine, irinotecan, bisoprolol, and anti-VEGF agents, no statistically significant association between genotype and response was found. CONCLUSION: The studies analyzed in this review suggest a strong correlation between genetic variability and individual drug responses, supporting the use of pharmacogenetics for treatment optimization. However, for certain drugs like metformin or quetiapine, the influence of genotype on their response remains unclear. More studies with larger sample sizes, greater ethnic diversity, and consideration of non-genetic factors are needed. The lack of standardization in analysis methods and accessibility to genetic testing are significant challenges in this field. As a conclusion, pharmacogenetics shows immense potential in personalized medicine, but further research is required.

RESUMEN

Desde los años ochenta se ha explorado el tratamiento para el virus de la hepatitis C, aunque en ese entonces los medicamentos disponibles eran poco toleradas y poco eficaces. En el 2011, la introducción de antivirales de acción directa transformó significativamente el curso de la enfermedad, logrando tasas de curación superiores al 90 % en los pacientes. Este avance ha permitido prevenir complicaciones futuras con efectos adversos mínimos. La presente revisión aborda la línea de tiempo del descubrimiento de los antivirales, su mecanismo de acción, sus indicaciones y potencial impacto en la salud pública.

Since the 1980s, the treatment of hepatitis C has been explored, although at that time, the available medications were poorly tolerated and ineffective. In 2011, the introduction of direct-acting antivirals significantly transformed the course of the disease, achieving cure rates of over 90% in patients. This advance has made it possible to prevent future complications with minimal adverse effects. This review addresses the timeline of the discovery of antivirals, their mechanism of action, and their impact on medicine.

RESUMEN

BACKGROUND: Adalimumab biosimilar MSB11022 (Idacio ®) has been approved for the same indications as its originator (Humira ®), based on findings from clinical trials in plaque psoriasis. Data on its efficacy and safety in inflammatory bowel disease, however, are scarce. METHODS: Retrospective, observational study of 44 patients with inflammatory bowel disease: 30 were treated with originator adalimumab, 5 were directly started on MSB11022, and 9 switched from originator to biosimilar adalimumab. To evaluate the effectiveness of the use of adalimumab in inflammatory bowel disease, both laboratory markers (fecal calprotectin and C-reactive protein) and scales that measure the activity of inflammatory bowel disease using specific scales (Harvey-Bradshaw Index (HBI) have been usEd.) for Crohn's disease and Mayo Score for Ulcerative Colitis. Efficacy was evaluated by recording the adverse effects that could occur with the administration of adalimumab (original or biosimilar). The success of the switch was determined by analyzing meaningful differences in effectiveness and safety criteria. Concomitant therapy and the need for dose intensification were also analyzed. Objective of this study was to assess the effectiveness and safety of biosimilar adalimumab in adalimumab-naïve patients and patients switched from originator adalimumab. RESULTS: No significant differences were observed in clinical disease activity (P=.317) or biochemical parameters [fecal calprotectin (P=.445) and C-reactive protein P=.661)] after the switch from the originator adalimumab to MSB11022. There was not a significant reduction in the concomitant use of corticosteroids and thiopurines (P=.157). No emergency room visits or hospitalizations were observed during the study period and none of the patients experienced serious adverse effects. CONCLUSIONS: Between originator adalimumab and biosimilar-start cohorts, no differences were observed, between originator adalimumab and switch cohorts, no significant differences were found either, and with the pre- and post-switch to biosimilar comparison, 2 of the 9 patients experienced AEs after the switch. The biosimilar showed a favorable safety profile (one patient with a serious adverse effect (rash) with biosimilar discontinued treatment) and no significant changes to clinical or biochemical parameters were observed after the switch.

RESUMEN

INTRODUCTION: New generation helixone dialyzers has recently been developed as part of the ongoing effort to improve dialyzer hemocompatibility and avoid adverse reactions to synthetic dialyzers. This study aimed to assess the performance and albumin loss of this new dialyzer series in hemodiafiltration and compare it with the previous generation helixone series. MATERIAL AND METHODS: A prospective study was conducted in 19 patients. Each patient underwent eight dialysis sessions with the same routine dialysis parameters; only the dialyzer varied: FX60 CorDiax, FX CorAL 60, FX600 CorDiax, FX CorAL 600, FX80 CorDiax, FX CorAL 80, FX800 CorDiax, and FX CorAL 800. The reduction ratios (RR) of urea, creatinine, ß2-microglobulin, myoglobin, kappa-free immunoglobulin light chains (κFLC), prolactin, α1-microglobulin, α1-acid glycoprotein, lambda immunoglobulin light chains (λFLC), and albumin were compared intra-individually. Dialysate albumin loss was also measured. RESULTS: All treatments were well tolerated. The mean amount of replacement fluid ranged from 31 to 34 L. Comparison of dialysis treatments showed no differences between small molecules and even up to those the size of ß2-microglobulins. Little differences were found between myoglobin, κFLC, prolactin, α1-microglobulin, and λFLC RRs, and only FX80 CorDiax was slightly superior to the others. Mean dialysate albumin losses were similar, with less than 2.5 g lost in each dialyzer. The FX80 CorDiax showed slightly higher global removal scores than the other dialyzers evaluated, except for FX CorAL 800. CONCLUSION: The new generation helixone dialyzers series has been updated to minimise the risk of adverse reactions, while maintaining the effectiveness and albumin loss achieved by the previous most advanced helixone generation.

RESUMEN

OBJECTIVES: Some concerns persist regarding the safety of semaglutide. The objective of this updated meta-analysis is to assess the risk of acute pancreatitis with the use of semaglutide, assessing the results according to the different administration regimens. METHODS: We performed an updated meta-analysis of randomised, placebo-controlled studies of semaglutide therapy that report acute pancreatitis. This meta-analysis was performed in line with PRISMA guidelines. A global and stratified analysis according to the therapeutic scheme used was performed using the fixed-effects model. RESULTS: Twenty-one eligible trials of semaglutide, including 34,721 patients, were identified and considered eligible for the analyses. Globally, semaglutide therapy was not associated with an increased risk of acute pancreatitis (OR 0.7; 95% CI 0.5-1.2, I2 0%). When we analysed the studies according to the different schemes used, the results were similar (group with oral semaglutide: OR 0.40; 95% CI 0.10-1.60, I2 0%; group with low subcutaneous doses of semaglutide: OR 0.80; 95% CI 0.40-1.90, I2 0%; group with high subcutaneous doses of semaglutide: OR 0.70; 95% CI 0.50-1.20, I2 0%; interaction p-value=0.689). CONCLUSION: This updated meta-analysis demonstrates that the use of semaglutide is not associated with an increased risk of acute pancreatitis compared to placebo. In the stratified analysis, the results were similar with the different semaglutide regimens analysed.

RESUMEN

RESUMEN Introducción: Las reacciones adversas a medicamentos (RAM) son manifestaciones clínicas o de laboratorio no deseadas que se relacionan con el consumo de medicamentos. Las RAM se asocian con un riesgo significativo de morbimortalidad e ingresos hospitalarios. Los antipsicóticos poseen una reducida ventana terapéutica y se han relacionado con la manifestación de una diversidad de RAM. Objetivo: Evaluar el patrón de las RAM debido a fármacos antipsicóticos, detectadas en pacientes atendidos en el Instituto Nacional de Psiquiatría Ramón de la Fuente Muñiz entre diciembre de 2021 y mayo de 2022. Métodos: Estudio observacional, descriptivo, prospectivo y transversal de una serie de casos. La gravedad, la severidad y la calidad de la información de la notificación de las RAM se definieron conforme a la NOM-220-SSA1-2016, instalación y operación de la farmacovigilancia, mientras que la causalidad se determinó mediante el algoritmo de Naranjo. Resultados: La incidencia de las RAM fue del 59% y se detectó una o más RAM en 52 de los 88 pacientes que estaban en tratamiento antipsicótico durante el periodo de estudio. El 45% de las RAM tuvo una causalidad probable y el 55%, posible; únicamente tres RAM se clasificaron como graves, debido a que prolongaron la estancia hospitalaria y pusieron en peligro la vida del paciente. Conclusiones: Las RAM de los sistemas gastrointestinal y endocrino fueron las más incidentes, y la hiperprolactinemia fue la más frecuente. La olanzapina y clozapina fueron los medicamentos que más RAM provocaron. Se recomienda fomentar la cultura de notificación y seguimiento de RAM causadas por fármacos antipsicóticos.

ABSTRACT Introduction: Adverse Drug Reactions (ADR) are unwanted clinical or laboratory manifestations that are related to drug use. ADR are common and are associated with significant risk of morbidity, mortality and hospital admissions. Antipsychotics have a reduced therapeutic window, and have been related to the manifestation of a variety of ADR. Objetive: To evaluate the pattern of ADRs due to antipsychotic drugs detected in patients treated at the Ramón de la Fuente Muñiz National Institute of Psychiatry between December 2021 and May 2022. Methods: Observational, descriptive, prospective and cross-sectional study of a series of cases. The seriousness, severity, and quality of the information in the notification of the ADR were defined in accordance with NOM-220-SSA1-2016, Installation and Operation of Pharmacovigilance, while causality was determined using the Naranjo algorithm. Results: The incidence of ADRs was 59%, with one or more ADR detected in 52 of the 88 patients who were receiving antipsychotic treatment during the study period. Forty-five percent of the ADR had probable causality and 55% possible; only three ADR were classified as serious as they prolonged the hospital stay and endangered the patient's life. Conclusions: The ADR of the gastrointestinal and endocrine systems were the most incidental, with hyperprolactinemia being the most frequent. Olanzapine and clozapine were the medications that caused the most ADR. It is recommended to promote the culture of notification and follow-up of ADR caused by antipsychotic drugs.

RESUMEN

Los anticonceptivos orales combinados constituyen hoy en día uno de los métodos anticonceptivos más populares a nivel mundial. Su composición consiste en una combinación de análogos de hormonas sexuales femeninas que se administran en bajas dosis diarias, manteniendo constante su concentración sanguínea y evitando de esta forma los cambios en el eje endócrino que estimulan la ovulación. Con el objetivo de recrear los procesos fisiológicos, la mayoría de las formulaciones comprenden un intervalo de 4 a 7 días libres de hormonas en el cual se genera el sangrado por deprivación.A partir de una viñeta clínica en la que una paciente sana desea posponer su hemorragia por deprivación, y tras realizar una búsqueda bibliográfica que prioriza las investigaciones más recientes y de mejor calidad, la autora revisa la evidencia sobre el uso de hormonas sin intervalo libre, especialmente su efectos sobre la eficacia y la incidencia de efectos adversos. (AU)

Nowadays, combined oral contraceptives are one of the most popular contraceptive methods worldwide. Its composition consists of a combination of similar female sex hormones administered in low daily doses, keeping their blood concentration constant and thus avoiding changes in the endocrine axis that stimulate ovulation. In order to recreate physiological processes, most formulations include an interval of 4 to 7 hormone-free days in which withdrawal bleeding occurs.Starting from a clinical vignette in which a healthy patient desires to postpone her withdrawal bleeding, and after conducting a bibliographic search that prioritizes the most recent and best-quality research, the author reviews the evidence about the use of hormones without free interval, especially their effects on efficacy and the incidence of adverse effects.

RESUMEN

Background: Close friends are often an overlooked group of bereaved people. This study is based on a sub-project on young adults who experienced the loss of a close friend in the terrorist attack on Utøya, Norway, on 22 July 2011.Objective: The aim of this longitudinal study was to explore the relationship between complicated grief reactions, the need for help, and help received after losing a close friend to a traumatic death.Method: In total, data from 89 people (with a mean age of 21 years, 76.4% female) were collected at one or more of the four time-points: 18, 28, 40, and 102 months after the incident. Latent growth modelling was used to analyse levels of grief reactions and change over time, experienced need for help, and help received.Results: According to the results, the bereaved friends in our study were profoundly impacted by the loss and experienced level of reactions indicating complicated grief (mean scores on the Inventory of Complicated Grief varied from 36.2 to 23.7). A need for help was related to a decrease in grief symptoms, whereas a prolonged need for help was related to no reduction or an increase in grief. Received help was not related to decrease in grief symptoms.Conclusions: These findings underscore the need for continuous professional help, and demonstrate that the present help measures used after traumatic events may not adequately meet the needs of close bereaved friends. This emphasizes the importance of acknowledging friends as bereaved and that follow-up measures should also include this group. Finally, the study highlights the need to learn more about how professional can help bereaved friends.

Young adults who experience the traumatic loss of a close friend may experience levels of grief reactions indicating complicated grief.The need for help reported after experiencing the loss of a close friend is high; this is also the case when some time has passed since the loss.Bereaved friends need more acknowledgement, and help measures after traumatic events often do not meet their need for help and follow-up after the loss.

RESUMEN

Objetivo: El objetivo de este estudio es evaluar los efectos de la vacunación contra el SARS-CoV-2 sobre el patrón convulsivo en pacientes pediátricos con epilepsia que acudieron a nuestro centro terciario en la ciudad de Bogotá, Colombia. Pacientes y métodos: Se pidió a los niños con epilepsia que fueron tratados en nuestro centro y que habían recibido la vacuna contra el SARS-CoV-2 y a sus cuidadores que informaran de su experiencia después de la vacunación. Se documentaron la edad, el sexo, la edad de inicio de la epilepsia, la duración de la epilepsia, el tipo de epilepsia, la frecuencia de las convulsiones, el número de medicamentos, el tiempo transcurrido desde la última crisis, los esquemas de vacunación y las convulsiones dos semanas después de la vacunación. Resultados: Se incluyó a 101 pacientes con epilepsia (58%, hombres; y 42%, mujeres). La edad promedio fue de 11 años, el 73% tenía epilepsia focal, y el 27%, generalizada. Veintiuno cumplían los criterios para la epilepsia refractaria y 11 tenían antecedentes personales de convulsiones febriles. Cuarenta y siete pacientes habían sido vacunados con la vacuna de Sinovac; 41, con Pfizer; 12, con Moderna; y uno, con CoronaVac. Tres pacientes presentaron convulsiones 24 horas después de la aplicación de la vacuna sin una relación clara entre la vacunación y la frecuencia de las convulsiones, y un paciente requirió ingreso en el hospital por una convulsión prolongada. Conclusión: La vacunación contra el SARS-CoV-2 en pacientes pediátricos con epilepsia es segura. Aproximadamente el 3% de los pacientes con epilepsia podría eventualmente tener convulsiones en el período posterior a la vacunación.

Aim: The objective of this study is to evaluate effects of SARS-CoV-2 vaccination on seizure pattern in paediatric patients with epilepsy that attended our tertiary center in the city of Bogotá, Colombia. Patients and methods: Children with epilepsy who were treated at our center and have had SARS-CoV-2 vaccination and their caregivers were asked to report their experience following vaccination. We documented age, sex, age at onset of epilepsy, duration of epilepsy, epilepsy type, seizure frequency, number of medications, time from last crisis, vaccination schemes, and seizures two weeks after vaccination. Results: One hundred and one patients with epilepsy were included (58%, male; and 42%, female). The average age was 11 years, 73% had focal epilepsy, and 27%, generalized. Twenty-one fulfilled criteria for refractory epilepsy and 11 had a personal history of febrile seizures. Forty-seven patients had been vaccinated with Sinovac’s vaccine; 41 patients, with Pfizer’s; 12 patients, with Moderna’s; and one, with CoronaVac’s. Three patients presented seizures 24 hours after the application of the vaccine with no clear relation between vaccination and seizure frequency, and one patient required admission to the hospital for a prolonged seizure. Conclusion: Vaccination against SARS-CoV-2 in paediatric patients with epilepsy is safe. Approximately 3% of patients with epilepsy could eventually have seizures in the post-vaccination period.(AU)

RESUMEN

Fundamentos: Una consulta habitual desde el inicio de la campaña de vacunación frente a la COVID-19 fue la relacionada con personas que tienen antecedentes de alergia a fármacos u otras vacunas. El objetivo del estudio fue describir lo ocurrido tras la administración de la vacuna frente a la COVID-19 en personas con antecedentes de alergia moderada y grave, en un Centro de Urgencias de Atención Primaria (CUAP). Métodos: Se realizó un estudio observacional descriptivo con sesenta y cuatro personas que tenían antecedentes de alergia moderada y grave, vacunadas en CUAP, entre mayo y octubre de 2021, en el Barcelonés Nord i Maresme (provincia de Barcelona), previa valoración por farmacólogos y farmacéuticos de Atención Primaria. Se calculó el porcentaje de personas con acontecimientos adversos ocurridos tras la vacunación en el transcurso de su estancia en el CUAP, los tipos detectados y la gravedad. Posteriormente, se realizó una encuesta telefónica para conocer la satisfacción de los pacientes. Se realizó un análisis descriptivo (cálculo de proporciones). Resultados: La media de edad de las personas participantes fue de 49,7 años (de doce a noventa y cuatro años) y el 90,6% fueron mujeres. El 87,5% de las vacunas administradas fue Comirnaty ®. Se detectaron acontecimientos adversos ocurridos tras la vacunación en quince pacientes (23,4%), de los que en cuatro casos (6,25%) fueron manifestaciones de hipersensibilidad, todas catalogadas como leves. Los motivos de vacunación fueron antecedentes de alergia a AINE (45,3%), antibióticos (32,8%), analgésicos (17,2%), vacunas (28,1%), otras sustancias (40,6%) y anafilaxia (26,6%). El grado de satisfacción general fue de 9,11 (sobre 10). Conclusiones: El porcentaje de pacientes con antecedentes de anafilaxia y reacciones alérgicas a medicamentos que presentan reacciones de hipersensibilidad a las vacunas frente a la COVID-19 es del 6,25% y todas son leves.(AU)

Background: A common consultation since the beginning of the vaccination campaign against COVID-19 was related to people with a history of allergy to drugs or other vaccines. The objective of the study was to describe what happened after the administration of the vaccine against COVID-19 in people with a history of moderate and severe allergy, vaccinated against COVID-19 in a Primary Care Emergency Center (PCEC). Methods/ Observational descriptive study with sixty-four people with a history of moderate and severe allergy was carried out, vaccinated in PCEP, between May and October 2021, in the Barcelonés Nord and Maresme (Barcelona province), after assessment by primary care pharmacologists and pharmacists. The percentage of people with adverse events that occurred after vaccination during their stay in the PCEP, the types detected and severity were calculated. Subsequently, a telephone survey was conducted to determine patient satisfaction. A descriptive analysis (calculation of proportions) was performed. Results: The mean age of 49.7 years (from twelve to ninety-four years) and 90.6% were women. 87.5% of the administered vaccines were Comirnaty ® . Adverse events occurring after vaccination were detected in fifteen patients (23.4%), of whom four (6.25%)were manifestations of hypersensitivity, all classified as mild. The reasons for vaccination were a history of allergy to NSAIDs (45.3%), antibiotics (32.8%), analgesics (17.2%), vaccines (28.1%), other substances (40.6%) and anaphylaxis (26.6%). The degree of generalsatisfaction was 9.11 (out of 10). Conclusions: The percentage of patients with a history of anaphylaxis and allergic drug reactions who present hypersensitivityreactions to COVID-19 vaccines is 6.25% and all are mild.(AU)

RESUMEN

Fundamento la toxicidad asociada a los tratamientos de quimioterapia y radioterapia eleva la morbilidad y la mortalidad en los pacientes oncológicos. Objetivo diseñar un modelo predictivo de toxicidad de la quimioterapia y la radioterapia en el paciente oncológico quirúrgico. Métodos estudio analítico, de casos y controles, en pacientes oncológicos quirúrgicos que cumplieron los criterios de inclusión para la predicción de toxicidad preoperatoria, en el periodo enero a diciembre de 2022, en el Hospital Provincial Docente Oncológico María Curie, de Camagüey. Mediante el paquete estadístico Statistical Package for the Social Sciences, se seleccionó una muestra aleatoria de 334 pacientes, 197 sin toxicidad (grupo control) y 137 con toxicidad (grupo de estudio). Se realizó estimación de predictores de toxicidad mediante regresión logística binaria. Se seleccionó el modelo de mejor ajuste. Resultados el modelo en el paso tres predice un porcentaje global de 83,5 % con respecto a los valores observados. La sensibilidad resultó ser de 81,8; y la especificidad, 84,8. El modelo presentó buen poder discriminativo. Las variables en la ecuación fueron: hipertensión arterial, fracción de eyección del ventrículo izquierdo y anemia. La comparación de la predicción con la realidad, mediante curva Receiver Operating Characteristic determinó un área bajo la curva de 0,901. Conclusión se obtuvo una función de regresión logística que permitió la estimación de la probabilidad de toxicidad en pacientes oncológicos quirúrgicos electivos, la cual proporcionó una herramienta para su predicción desde el preoperatorio.

Foundation the toxicity associated with chemotherapy and radiotherapy treatments increases morbidity and mortality in cancer patients. Objective to design a predictive model of chemotherapy and radiotherapy toxicity in surgical cancer patients. Methods analytical, case-control study, in surgical oncology patients who met the inclusion criteria for the prediction of preoperative toxicity, from January to December 2022, at the María Curie Provincial Teaching Oncology Hospital in Camagüey. Using the Statistical Package for the Social Sciences, a random sample of 334 patients was selected, 197 without toxicity (control group) and 137 with toxicity (study group). Toxicity predictors were estimated using binary logistic regression. The model with the best fit was selected. Results the model in step three predicts an overall percentage of 83.5% with respect to the observed values. The sensitivity turned out to be 81.8; and the specificity, 84.8. The model presented good discriminative power. The variables in the equation were: arterial hypertension, left ventricular ejection fraction, and anemia. The comparison of the prediction with reality, using the Receiver Operating Characteristic curve, determined an area under the curve of 0.901. Conclusion a logistic regression function was obtained that allowed the estimation of the toxicity probability elective surgical cancer patients, which provided a tool for its prediction from the preoperative period.

RESUMEN

La vacunación de la gripe en embarazadas muestra una clara relación beneficio/riesgo. En la actualidad se están desarrollando vacunas contra la gripe utilizando nuevas plataformas. Es imprescindible analizar la seguridad de estas nuevas vacunas en este grupo poblacional, infrarrepresentado en los ensayos clínicos. En la temporada 2019-2020 se aconsejó una vacuna obtenida en cultivo celular a las embarazadas en 2comunidades autónomas. Se recogió información de los centros de vacunación y de farmacovigilancia de ambas comunidades. La tasa de notificación de casos de acontecimientos adversos tras la vacunación en embarazadas fue de 4,02/100.000 dosis administradas y, en mujeres de 18 a 64 años no embarazadas, de 5,9/100.000 dosis administradas. La tasa de acontecimientos adversos notificados fue de 8,04 y 17,74, respectivamente. No se notificaron abortos espontáneos, prematuridad ni malformaciones fetales. Este análisis señala la seguridad en embarazadas de la vacuna de la gripe obtenida de cultivos celulares.(AU)

Influenza vaccination in pregnant women shows a clear benefit/risk ratio. Influenza vaccines are currently being developed using new platforms. It is essential to analyze the safety of these new vaccines in this population group, underrepresented in clinical trials. In the 2019-2020 season, a vaccine obtained in cell culture was recommended to pregnant women in 2autonomous communities. Information is collected from the vaccination and pharmacovigilance centers of both communities. The reporting rate of adverse events after vaccination in pregnant women was 4.02/100,000 doses administered, and in non-pregnant women aged 18-64 years it was 5.9/100,000 doses administered. The rate of adverse events reported was 8.04 and 17.74, respectively. No spontaneous abortions, prematurity or fetal malformations were reported. This analysis suggests the safety in pregnant women of the influenza vaccine obtained from cell cultures.(AU)
