Intra-amniotic infection and/or inflammation is associated with fetal cardiac concentric hypertrophy and diastolic dysfunction in preterm labor and preterm prelabor rupture of membranes.

BACKGROUND: Preterm delivery is associated with cardiovascular remodeling and dysfunction in children and adults. However, it is unknown whether these effects are caused by the neonatal consequences of preterm birth or if these are already present in utero. OBJECTIVE: We evaluated fetal cardiac morphology and function in fetuses of mothers admitted for preterm labor or preterm prelabor rupture of membranes and the association of these changes with the presence of intra-amniotic infection and/or inflammation. STUDY DESIGN: In this prospective cohort study, fetal echocardiography and amniocentesis were performed at admission in singleton pregnant women with preterm labor and/or preterm prelabor rupture of membranes between 24.0 and 34.0 weeks' gestation with (intra-amniotic infection and/or inflammation group, n=41) and without intra-amniotic infection and/or inflammation (non-intra-amniotic infection and/or inflammation, n=54). Controls (n=48) were outpatient pregnant women without preterm labor or preterm prelabor rupture of membranes. Intra-amniotic infection was defined by a positive amniotic fluid culture or positive 16S ribosomal RNA gene. Intra-amniotic inflammation was defined by using the amniotic fluid interleukin-6 cutoff levels previously reported by our group being >1.43 ng/mL in preterm prelabor rupture of membranes and >13.4 ng/mL in preterm labor. Fetal cardiac morphology and function was evaluated using echocardiography, and troponin-I and N-terminal pro-brain natriuretic peptide concentrations were measured in amniotic fluid from women with preterm labor or preterm prelabor rupture of membranes and compared with 20 amniotic fluid Biobank samples obtained for reasons other than preterm labor or preterm prelabor rupture of membranes or cardiac pathology. The data were adjusted for the estimated fetal weight below the 10th percentile and for preterm prelabor rupture of membranes at admission and also for gestational age at amniocentesis when amniotic fluid biomarkers were compared. RESULTS: From 2018 to 2021, 143 fetuses were included; 95 fetuses were from mothers admitted with a diagnosis of preterm labor or preterm prelabor rupture of membranes, and among those, 41 (28.7%) were in the intra-amniotic infection and/or inflammation group and 54 (37.8%) were in the non-intra-amniotic infection and/or inflammation group. A total of 48 (33.6%) fetuses were included in the control group. Fetuses with preterm labor and/or preterm prelabor rupture of membranes had signs of subclinical cardiac concentric hypertrophy (median left wall thickness of 0.93 [interquartile range, 0.72-1.16] in the intra-amniotic infection and/or inflammation group; 0.79 [0.66-0.92] in the non-intra-amniotic infection and/or inflammation group; and 0.69 [0.56-0.83] in controls; P<.001) and diastolic dysfunction (tricuspid A duration 0.23 seconds [0.21-0.25], 0.24 [0.22-0.25], and 0.21 [0.2-0.23]; P=.007). Systolic function was similar among groups. Higher values of amniotic fluid troponin I (1413 pg/mL [927-2334], 1190 [829-1636], and 841 [671-959]; P<.001) and N-terminal pro-brain natriuretic peptide were detected (35.0%, 17%, and 0%; P=.005) in fetuses with preterm labor or preterm prelabor rupture of membranes when compared with the control group. The highest N-terminal pro-brain natriuretic peptide concentrations were found in the intra-amniotic infection and/or inflammation group. CONCLUSION: Fetuses with preterm labor or preterm prelabor rupture of membranes showed signs of cardiac remodeling and subclinical dysfunction, which were more pronounced in those exposed to intra-amniotic infection and/or inflammation. These findings support that the cardiovascular effects observed in children and adults born preterm have, at least in part, a prenatal origin.

Medication guide for dose adjustment and management of cardiotoxicity and lipid metabolic adverse events of oral antineoplastic therapy.

Objective: The management of cardiotoxicity concerning the use of oral antineoplastic agents (OAAs) is a challenge for healthcare professionals. Our objective was to create a comprehensive medication management guide with dose adjustment recommendations on OAAs concerning cardiotoxic and lipid metabolic adverse events (AEs) to assist healthcare professionals when prescribing OAAs. Materials and methods: A review of the available information on all dose adjustments necessary to safely prescribe and dispense OAAs concerning cardiotoxicity was conducted. In January 2023, we identified all OAAs authorized by the European Medicines Agency (EMA). For each drug, the latest summary of product characteristics (SPC) approved by the EMA and the tertiary data source Lexicomp® were reviewed. Cardiotoxic AEs were recorded, namely, QT interval prolongation, decrease in left ventricular ejection fraction (LVEF), imbalances in blood pressure (hypertension and hypotension), alterations in heart rate (tachycardia and bradycardia), and thrombosis. Any available dose adjustment recommendations in case of an occurrence of these adverse events were collected. Results: In all, 93 different OAAs had been approved by the EMA and were reviewed. Among them, 51.6% have recognized cardiotoxic AEs and 10.8% can cause alterations in lipid metabolism. A total of 27 (29.0%) OAAs had specific recommendations regarding QT prolongation; 88.9% were listed in the SPC and 59.3% in Lexicomp®. Eight OAAs (9.68%) have reported a decrease in LVEF, and four of these drugs, namely, encorafenib, lorlatinib, ripretinib, and sunitinib, have specific management recommendations. Almost half (49.5%) of currently approved OAAs can potentially alter blood pressure; 34 (36.6%) of them have been reported to cause hypertension and 12 (12.9%) are related to hypotension. Tachycardia and/or bradycardia are associated with 22.6% and 8.6% of the evaluated drugs, respectively. Regarding thrombosis, 30 (32.3%) of the drugs analyzed included the appearance of a thrombus as a possible AE. Conclusions: More than half of the OAAs can produce cardiotoxic effects, with the most frequent being blood pressure alteration and QT interval prolongation with a non-depreciable incidence of LV dysfunction or thrombosis. Before starting the treatment, it is necessary to stratify baseline cardiovascular risk, plan a surveillance schedule, and consider referral to cardio-oncology units.

Complementary and alternative medicine in cancer patients: characteristics of use and interactions with antineoplastic agents.

PURPOSE: Our objectives were to analyze the use of complementary and alternative medicine (CAM) in cancer patients and to describe the incidence and characteristics of interactions between CAM and antineoplastic agents. METHODS: We performed an observational study in cancer outpatients at a university hospital. Variables were collected through a 22-item questionnaire. Potential interactions between CAM and antineoplastic agents were analyzed using the Lexicomp®, the About Herbs®, and the summary of product characteristics. Mechanism of action, reliability, and the potential clinical effect of interactions were analyzed. RESULTS: The study population comprised 937 patients, of whom 65% used CAM (70.6% herbal products, 25.8% dietary supplements, and 3.6% homeopathy). Female sex, younger age, and breast cancer were associated with more frequent use of CAM. The primary source of information about CAM was friends and family (43.5%). A total of 335 (57.1%) patients did not tell their doctor that they took CAM. The five most common CAM were chamomile, green tea, pennyroyal mint, linden, and rooibos. At least one interaction between CAM and antineoplastic agents was reported by 65.0% of CAM users (33.9% of all patients). Depending on the mechanism of action, 80% of CAM diminished the metabolism of the antineoplastic agents. CONCLUSION: Our results reveal a high incidence of interactions between CAM and antineoplastic agents. The most frequent CAM were herbal products. Family and friends were the primary sources of information that led patients to start taking CAM, and more than half of the patients did not tell their doctor that they were taking CAM.

Possible heart failure caused by osimertinib in a lung cancer patient.

INTRODUCTION: Osimertinib is a third-generation tyrosine kinase inhibitor (TKI) indicated for the treatment of epidermal growth factor receptor mutated non-small cell lung cancer (NSCLC). It has demonstrated better results concerning effectiveness than other TKIs for the same indication. However, despite a good safety profile, it could produce some cardiotoxicity that does not occur with other drugs of the same group. CASE REPORT: We report the evolution and management of a female patient diagnosed with NSCLC who developed a grade 3 cardiotoxicity due to treatment with osimertinib. This patient suffered from a left bundle branch block, dyslipidemia, and hypertension as cardiovascular risk factors. After a long period of treatment with osimertinib, she developed a severe heart failure (HF) with an important decrease in left ventricular ejection fraction (LVEF), which triggered an admission to the oncology unit for eight days. MANAGEMENT AND OUTCOMES: Treatment with osimertinib was first suspended and then resumed after stabilization of the HF. She also developed atrial fibrillation during admission and has required narrow cardiac monitoring and management since the debut of the HF. After evaluating the benefit-risk balance, osimertinib was reintroduced and the patient continues in treatment at the moment, although the baseline LVEF is not recovered. DISCUSSION: There is scarce evidence in the literature concerning HF and important LVEF decrease due to osimertinib. However, its severity and repercussion for the patient justify the thorough screening of cardiovascular risk factors before starting the therapy.

Smartphone-Based Ecological Momentary Assessment for the Measurement of the Performance Status and Health-Related Quality of Life in Cancer Patients Under Systemic Anticancer Therapies: Development and Acceptability of a Mobile App.

Background: We have defined a project to develop a mobile app that continually records smartphone parameters which may help define the Eastern Cooperative Oncology Group performance status (ECOG-PS) and the health-related quality of life (HRQoL), without interaction with patients or professionals. This project is divided into 3 phases. Here we describe phase 1. The objective of this phase was to develop the app and assess its usability concerning patient characteristics, acceptability, and satisfaction. Methods: The app eB2-ECOG was developed and installed in the smartphone of cancer patients who will be followed for six months. Criteria inclusion were: age over 18-year-old; diagnosed with unresectable or metastatic lung cancer, gastrointestinal stromal tumor, sarcoma, or head and neck cancer; under systemic anticancer therapies; and possession of a Smartphone. The app will collect passive and active data from the patients while healthcare professionals will evaluate the ECOG-PS and HRQoL through conventional tools. Acceptability was assessed during the follow-up. Patients answered a satisfaction survey in the app between 3-6 months from their inclusion. Results: The app developed provides a system for continuously collecting, merging, and processing data related to patient's health and physical activity. It provides a transparent capture service based on all the available data of a patient. Currently, 106 patients have been recruited. A total of 36 patients were excluded, most of them (21/36) due to technological reasons. We assessed 69 patients (53 lung cancer, 8 gastrointestinal stromal tumors, 5 sarcomas, and 3 head and neck cancer). Concerning app satisfaction, 70.4% (20/27) of patients found the app intuitive and easy to use, and 51.9% (17/27) of them said that the app helped them to improve and handle their problems better. Overall, 17 out of 27 patients [62.9%] were satisfied with the app, and 14 of them [51.8%] would recommend the app to other patients. Conclusions: We observed that the app's acceptability and satisfaction were good, which is essential for the continuity of the project. In the subsequent phases, we will develop predictive models based on the collected information during this phase. We will validate the method and analyze the sensitivity of the automated results.

A New Methodology to Estimate Drug Cost Avoidance in Clinical Trials: Development and Application.

Background: Oncology clinical trials can lead to relevant financial savings in drug acquisition for healthcare providers. Considerable methodological heterogeneity is observed among previous studies estimating these savings. Methods: We developed a methodology to estimate the economic benefit obtained from the enrollment of patients into clinical trials through the analysis of drug cost avoidance. We designed a decision algorithm to determine if a clinical trial is associated with drug cost avoidance. This algorithm is based on five scenarios according to the availability or not of standard treatment, the presence or absence of a control arm (placebo or active treatment), and the provider of the medication. We considered as reference the cost of the standard treatment that the patient would have received in routine clinical practice. We standardized drug doses and treatment durations according to the literature. Costs were considered from a National Health System perspective. We applied this methodology at a single, research-active University Hospital in 2019. A cost avoidance analysis per trial and patient was carried out on cancer patients. Results: We analyzed 140 trials in which 198 patients were recruited. Drug cost avoidance was found in 120 trials (85.7%). The estimated total drug cost avoidance amounted to over €3,200,000. Melanoma and genitourinary tumors were the tumor types associated with the highest cost avoidance. The average drug cost avoidance per patient was €16,245. Conclusion: We describe a standardized method to estimate drug cost avoidance in clinical trials. We have applied it to all ongoing oncology clinical trials in our center. This methodology could be valuable for other centers to analyze the potential saving of clinical trials.

Potential negative pharmacodynamic interaction of spironolactone and abiraterone in two prostate cancer patients.

INTRODUCTION: Spironolactone when combined with abiraterone in metastatic castration-resistant prostate cancer (mCRPC) may theoretically exert androgenic properties, thereby compromising the therapeutic effectiveness of abiraterone. CASE REPORT: Two patients with a medical history of cardiovascular disease and mCRPC combined spironolactone within the course of abiraterone regimen. The abiraterone-spironolactone interaction was identified using the Lexicomp® interaction tool (classified as risk C). MANAGEMENT & OUTCOME: Spironolactone treatment was maintained as it was considered beneficial due to the cardiac condition. The prostate-specific antigen (PSA) levels started to rise when these two drugs were used together. Eventually, tumour progression was observed. DISCUSSION: There is increasing evidence that spironolactone behaves as a selective androgen receptor modulator. Strategies to overcome abiraterone-spironolactone interaction could involve the use of eplerenone, although this drug is also controversial. The best strategy should imply a multidisciplinary evaluation by cardiologists and oncologists.

Medication guide for the perioperative management of oral antineoplastic agents in cancer patients.

BACKGROUND: Oral antineoplastic agents (OAAs) are high-risk drugs that may increase the risk of bleeding, difficulty in wound healing, or produce alterations in coagulation and/or platelet aggregation. These aspects had to be highly considered throughout the entire perioperative process. Our aim was to create a comprehensive management medication guide based on reconciliation and dose adjustment recommendations for OAAs in patients undergoing a surgical intervention. RESEARCH DESIGN AND METHODS: We analyzed all OAAs approved by the EMA in November 2020. We assessed data related to dose adjustment, drug reconciliation, coagulation disturbances, or anticoagulant interactions from the FDA and EMA summary of product characteristics. RESULTS: We analyzed 67 OAAs. We identified that 51 (76.2%) OAAs can produce alteration in the platelet count, 12 (17.9%) affect the wound healing and recovery process, and 32 (47.8%) require control and monitoring in case of combination with anticoagulants. Only 13 (19.4%) OAAs, most of them antiangiogenics, have specific recommendations for temporary suspension before surgery. CONCLUSIONS: Most OAAs require perioperative monitoring. This review can serve as an easy (simple, effective) tool to help healthcare professionals involved in patient care to manage OAAs during the perioperative process.

Assessment of diarrhea as side effect of oral targeted antineoplastic agents in clinical practice.

BACKGROUND: Diarrhea is one of the most frequent class adverse events associated with targeted oral antineoplastic agents (OAAs). Our objective was to analyze the incidence, characteristics, and severity of diarrhea in cancer patients in clinical practice. METHODS: An observational, longitudinal, and prospective study of cancer outpatients treated with targeted OAAs was carried out in a tertiary hospital. Targed OAAs analyzed were anaplastic lymphoma kinase inhibitors, BCR-ABL inhibitors, cyclin-dependent kinase inhibitors, epidermal growth factor receptor inhibitors, mTOR inhibitors, poly (ADP-ribose) polymerase inhibitors, and vascular endothelial growth factor receptor inhibitors. Patients were given a data collection form to record daily the number, severity (CTCAE version 5.0), and characteristics of stools during the first 30 days of treatment with OAAs. Multivariate analysis was performed to identify risk factors associated with the incidence of diarrhea. RESULTS: We analyzed 240 patients, of whom 28.7% experienced diarrhea (25.4% grades 1-2 and 3.3% grades 3-4). Patients treated with EGFR and VEGFR inhibitors had a higher incidence of diarrhea. The multivariate analysis revealed that taking the OAA with food was associated with a lower risk of diarrhea (OR = 0.404 [0.205-0.956], p = 0.038). CONCLUSIONS: More than a third of patients in treatment with OAAs presented diarrhea (any grade), and 22.1% of stools were semi-liquid/liquid. In multivariate analysis, taking the OAA on an empty stomach was associated with a statistically significant increase in the incidence of diarrhea.

Error Detection and Cost Savings With an Image-Based Workflow Management System Connected to a Computerized Prescription Order Entry Program for Antineoplastic Compounding.

OBJECTIVE: The aim of the study was to analyze both the prevalence of errors with the implementation of an image-based workflow management system during the antineoplastic compounding process, and the estimated costs associated with the negative clinical outcome if the errors had not been intercepted. METHODS: Three months after the implementation of Phocus Rx system at a hospital pharmacy department, the identification, classification (type, preparation stage, and cause), and potential severity degree (from negligible to catastrophic) of the errors intercepted were determined. The probability of an error causing an adverse event if it had reached the patient (from nil [0] to high [0.6]) and its consequences was estimated by a team of clinical pharmacists and physicians. Cost-effectiveness analysis from the hospital's perspective was performed. RESULTS: Overall, 9872 antineoplastic medications were prepared using Phocus Rx. The total compounding error rate was 0.8% (n = 78, 56 [69.2%] were related to incorrect dose, 20 [28.2%] to incorrect drug preparation or conditioning technique, and 2 [2.6%] were wrong drugs). Approximately 70% of the detected errors were classified as undetectable via the previous verification practice, with 11.55% judged to be potentially severe (n = 9) and 51.3% moderate (n = 29). Likelihood of occurrence of an adverse event was medium (0.4) to high (0.6) for 37.2% of the errors. Estimated cost ratio and return on investment were €4.21 and 321%, respectively. CONCLUSIONS: The implementation of Phocus Rx prevented antineoplastic preparation errors that would have reached the patient otherwise. In addition, acquisition of this technology was estimated to be cost-effective.

Potential and real drug interactions in patients treated with abiraterone or enzalutamide in clinical practice.

BACKGROUND: Abiraterone and enzalutamide, androgen receptor pathway inhibitors (ARPI) for the treatment of metastatic castration-resistant prostate cancer (mCRPC), are at high risk of potential drug interactions (PDIs). We aimed to describe PDIs and their management, and triggered adverse events (AEs) in clinical practice. METHODS: We conducted a cross-sectional study in mCRPC patients who started treatment with abiraterone or enzalutamide in a university hospital between August 1st, 2016 and July 31st, 2020. Lexicomp® was used to identify and analyze PDIs, and the clinical records to assess their management and the occurrence of AEs. RESULTS: We included 173 patients: 36.8% and 93.0% treated with abiraterone and enzalutamide, respectively, had at least 1 PDI. Globally, 6.3% of PDIs had X-risk (contraindication due to high probability of AE). Treatment was modified in 9.2% of patients and 9.8% suffered AEs due to PDIs. Factors associated with a higher risk of PDIs were polypharmacy (OR= 41.0, p  0.003) and treatment with enzalutamide (OR= 128.26, p < 0.001). CONCLUSIONS: At least two-thirds of patients treated with ARPI suffered a PDI. Overall, abiraterone would have a more favorable PDI profile. Knowing these interaction profiles may be helpful to develop a more efficient therapeutic follow-up and to select the safest treatment.

Acute pancreatitis in a patient treated with imatinib and gefitinib.

INTRODUCTION: Use of oral antineoplastic agents (OAAs) has increased significantly in recent years. OAAs currently represent 30-50% of all cancer treatments. Drug interactions are the most frequent drug-related problem affecting OAAs. We describe the case of a patient who presented acute pancreatitis, possibly induced by the concomitant use of imatinib and gefitinib. CASE REPORT: A female patient received imatinib and gefitinib for the treatment of chronic myeloid leukemia and lung adenocarcinoma, respectively. Liver function and pancreatic enzyme values gradually worsened after initiation of imatinib, and the patient was diagnosed with acute pancreatitis. MANAGEMENT AND OUTCOMES: Imatinib was discontinued owing to pancreatic toxicity. Gefitinib was subsequently discontinued owing to tumor progression. The patient received supportive measures for pancreatitis, although she eventually died 3 months after the onset of symptoms. DISCUSSION: To our knowledge, this is the first case in the medical literature of acute pancreatitis possibly induced by an interaction between imatinib and gefitinib. The interaction most likely arose because imatinib is a CYP2D6 inhibitor and could therefore impair the metabolism of gefitinib (a CYP2D6 substrate) and increase its serum concentration. This interaction is extremely rare. However, due to its severity, hepatic and pancreatic function should be carefully monitored in patients treated with imatinib and/or gefitinib and other inhibitors or inducers of CYP2D6 and CYP3A4.

Cancellations of elective surgical procedures due to inadequate management of chronic medications.

WHAT IS KNOWN AND OBJECTIVES: Inadequate management of chronic medication puts patients at risk and causes unnecessary suspension of surgical procedures. The objective of the study was to calculate the rate of cancellation of elective surgical procedures due to inadequate management of chronic medications and to analyse the underlying causes of cancellation. METHODS: We designed an analytic, observational, retrospective study of all elective surgical procedures performed from July to October 2017 in a tertiary hospital. The main variable was the percentage of surgeries cancelled owing to inadequate management of chronic medications. Other variables recorded included demographic characteristics, time between the preanaesthesia evaluation and surgery, drug involved, and the reason for incorrect management of the medication. RESULTS: During the study period, 5415 surgical procedures were programmed, and 793 (14.6%) were cancelled. Cancellations due to inadequate patient preparation accounted for 5.3% (42 cases), and 19 were related to incorrect medication management (2.4% of the total number of cancellations). The 19 patients, who were mostly men (73.7%), had a median age of 76 years (IQR 68-81). The drugs involved were acenocoumarol (6), enoxaparin (4), clopidogrel (4), direct-acting oral anticoagulants (2), acetylsalicylic acid (1), tocilizumab (1) and leflunomide (1). The reasons for drug mishandling were poor understanding of the anaesthesiology recommendations (15) and lack of a preanaesthesia evaluation (4). WHAT IS NEW AND CONCLUSION: Inadequate management of chronic medications (2.4%) is not the most frequent reason for cancellation, although it is one of the easiest to avoid. Based on our results, starting in October 2017, the Pharmacy Department began to offer a pharmaceutical service to patients with doubts about the preoperative management of chronic medications.

Cadmium levels in a representative sample of the Spanish adult population: The BIOAMBIENT.ES project.

Urinary cadmium levels (U-Cd) were measured in 1770 adults (aged 18-65 years) as a representative sample of the Spanish workforce. The geometric mean (GM) was 0.28 µg/l with 95% CI: 0.27-0.32 µg/l (GM: 0.20 µg/g 95% CI: 0.18-022 µg/g creatinine). The 95% percentile was 1.03 µg/l. U-Cd increased with age, with women showing higher U-Cd than men (p<0.001; 0.24 µg/g vs 0.17 µg/g). A multivariate analysis confirmed that sex, age and smoking habit significantly influence U-Cd. Smoking habit increases U-Cd by ∼90% per 10 years of age, almost twice the increase observed for non-smoking. Female smokers had 85% higher U-Cd than non-smokers, whereas the corresponding value for male smokers and non-smokers was 45%. No regional differences were observed with respect to the national reference level. The Spanish population studied here exhibits similar urinary cadmium levels to its European counterparts in Germany and slightly lower levels than in France, the Czech Republic, Italy and the United Kingdom. This paper provides the first baseline information concerning cadmium exposure in the Spanish adult population on a national scale. As such, these findings will help us to establish reference levels, follow temporal trends and identify high-exposure groups, thereby enabling comparisons with other countries and contributing to the improvement of public health and environmental quality.

Vitamin D supplementation review and recommendations for women diagnosed with breast or ovary cancer in the context of bone health and cancer prognosis/risk.

Vitamin D review and supplementation recommendations for women diagnosed with breast or ovary cancer have been defined in the context of bone health and cancer prognosis/risk taking as reference wider cancer patients and postmenopausal women. This specific group has been selected due to its higher osteoporosis risk versus postmenopausal women. Early vitamin D supplementation could help maintain bone health, as well as potentially enhance cancer survival rate. Factors considered for supplementation include daily dose, periodicity, chemical form, administration, and serum levels. Sufficient vitamin D serum levels are recommended to be above 30 ng/ml (75 nmol/l). Maintenance oral supplementation equivalent to a minimum daily dosage of 800-1000 IU (20-25 µg) cholecalciferol provided in a daily to monthly bases is preferred, also advised to start with higher dosages when vitamin D serum levels are <10 ng/ml (25 nmol/l). Calcidiol supplementation is more effective, making it advantageous for cases with very low or difficult to raise vitamin D serum levels.
