Transcriptional expression of SLC16A7 as a biomarker of occult lymph node metastases in patients with head and neck squamous cell carcinoma.

PURPOSE: Glucose is the main energy substrate of tumor cells. This study aims to assess whether the transcriptional expression of glucose metabolism-related genes is associated with occult lymph node metastases in head and neck squamous cell carcinoma (HNSCC) patients. METHODS: We examined the transcriptional expression of a panel of glucose metabolism-related genes in a cohort of 53 patients with HNSCC without cervical lymph node involvement at the time of diagnosis (cN0) and subsequently treated with elective neck dissection. RESULTS: Occult lymph node metastases were found in 37.7% (n = 20) of the patients. Among the analyzed genes, SLC16A7 exhibited the strongest association with the presence of occult lymph node metastases. Patients with occult lymph node metastases (cN0/pN +) had significantly lower SLC16A7 expression values (p = 0.001). Patients with low SLC16A7 expression (n = 17, 32.1%) had a frequency of occult lymph node metastases of 76.5%, while for patients with high SLCA16A7 expression (n = 36, 67.9%) it was 19.4% (P = 0.0001). A multivariable analysis showed that patients with low expression of SLC16A7 had a 12.6 times higher risk of developing occult lymph node metastases. CONCLUSION: cN0 HNSCC patients with low SLC16A7 expression had a higher risk of occult lymph node metastases.

Facial palsy after embolization with Squid® 12.

Endovascular procedures with liquid embolic agents such as ethylene-vinyl alcohol (EVOH) copolymers are indicated before surgical treatment of cervical paraganglioma. Consequently, these agents are now available as low viscosity formulations, one of which is Squid 12, which are demonstrating superior vascular penetration. Cases of facial paralysis secondary to embolization of cervical vascular lesions with classic embolic agents have been reported in the English literature, however, this complication has not been described with new generation options such as Squid 12.We describe the case of a 43-year-old patient with a left neck carotid paraganglioma. Embolization was performed under general anaesthesia before surgical excision. In the immediate postoperative period, the patient developed total left facial palsy. Since the imaging tests (Computed Tomography (CT) and Magnetic Resonance Imaging (MRI)) and neurological examination showed no involvement of additional cranial nerves (CN), we hypothesise that the main cause of this complication is ischemia of the vasa nervorum of CN VII secondary to embolization. Almost six months later, the patient continues to present total facial paralysis (Grade VI House-Brackmann facial paralysis scale), and palsy of the left CN X and XII as a complication secondary to surgical resection of the paraganglioma.This case is relevant since it is the first clinical case of permanent facial paralysis secondary to embolization with Squid 12.

Real-world prevalence and consequences of potential drug-drug interactions in the first-wave COVID-19 treatments.

WHAT IS KNOWN AND OBJECTIVE: Initial treatment recommendations of COVID-19 were based on the use of antimicrobial drugs and immunomodulators. Although information on drug interactions was available for other pathologies, there was little evidence in the treatment of COVID-19. The objective of this study was to analyse the potential drug-drug interactions (pDDIs) derived from the medication used in COVID-19 patients in the first pandemic wave and to evaluate the real consequences of such interactions in clinical practice. METHODS: Cohort, retrospective and single-centre study carried out in a third-level hospital. Adult patients, admitted with suspected COVID-19, that received at least one dose of hydroxychloroquine, lopinavir/ritonavir, interferon beta 1-b or tocilizumab and with any pDDIs according to "Liverpool Drug Interaction Group" between March and May 2020 were included. The possible consequences of pDDIs at the QTc interval level or any other adverse event according to the patient's medical record were analysed. A descriptive analysis was carried out to assess possible factors that may affect the QTc interval prolongation. RESULTS AND DISCUSSION: Two hundred and eighteen (62.3%) patients of a total of 350 patients admitted with COVID-19 had at least one pDDI. There were 598 pDDIs. Thirty-eight pDDIs (6.3%) were categorized as not recommended or contraindicated. The mean value difference between baseline and pDDI posterior ECG was 412.3 ms ± 25.8 ms vs. 426.3 ms ± 26.7 ms; p < 0.001. Seven patients (5.7%) had a clinically significant alteration of QTc. A total of 44 non-cardiological events (7.3%) with a possible connection to a pDDI were detected. WHAT IS NEW AND CONCLUSION: The number of pDDIs in patients admitted for COVID-19 in the first pandemic wave was remarkably high. However, clinical consequences occurred in a low percentage of patients. Interactions involving medications that would be contraindicated for concomitant administration are rare. Knowledge of these pDDIs and their consequences could help to establish appropriate therapeutic strategies in patients with COVID-19 or other diseases with these treatments.

Medication list assessment in Spanish hospital emergency departments.

BACKGROUND: Medication errors lead to morbidity and mortality among emergency department (ED) patients. An inaccurate medication history is one of the underlying causes of these errors. OBJECTIVES: This study was performed to determine the prevalence of patients with discrepancies between the medical list information contained in the clinical history compiled on admission to the ED and the list of medications patients are actually taking, to characterize the discrepancies found, and to analyze whether certain factors are associated with the risk of discrepancies. METHODS: We conducted a cross-sectional, descriptive, observational, multicenter study with an analytic component in the EDs of 11 hospitals in Spain. We compared pharmacist-obtained medication lists (PML) with ED-obtained medication lists (EDML). Discrepancy was defined as one or more differences (in drug or dosage or route of administration) between the EDML and PML. The endpoints were the proportion of patients with discrepancies in their home medical lists, and the prevalence of certain factors among patients with discrepancies and those without. RESULTS: We detected 1476 discrepancies in 387 patients; no discrepancies were found in 20.7%. The most frequent discrepancies involved incomplete information (44.2%) and omission (41.8%). In the bivariate analysis, age, number of medications, and Charlson comorbidity score were significantly associated with discrepancy. In the multivariate analysis, number of medications and hospital were the variables associated with discrepancy. CONCLUSIONS: The EDML differed from the list of medications patients were actually taking in 79.3% of cases. Incomplete information and omission were the most frequent discrepancies. Age, number of medications, and comorbidities were related to the risk of discrepancies.

[Recommendations for using oral antineoplastic and immunomodulating agents in oncohematology by enteral tube administration]. / Recomendaciones para la administración de antineoplásicos e inmunomoduladores orales por sonda enteral en oncohematología.

INTRODUCTION: Introduction and objective: in recent years, the number of oral antineoplastic and immunomodulating drugs in oncohematology has increased enormously. Often, these drugs must be administered to patients with enteral tube feeding or swallowing disorders, which causes safety problems when handling these drugs (many of them are classified as hazardous drugs). In addition, it is important to note that the administration of these drugs can also interact with enteral nutrition (EN). The objective of this study was to review and update the recommendations for the administration and handling of oral antineoplastic and immunomodulating drugs. Methods: a Working Group made up of pharmacists from the Pharmacy Group of The Spanish Society of Clinical Nutrition and Metabolism (SENPE) and the Clinical Nutrition Group of The Spanish Society of Hospital Pharmacy (SEFH) was created. A bibliographic review was carried out between 2015 and 2020 on the administration and handling of oral antineoplastic and immunomodulating drugs in oncohematology. The information about pharmaceutical specialties, dosage, presentation, brand names, instructions for oral or enteral tube administration, interactions with EN, precautions, and remarks for handling and administration was analyzed. Results: a total of 77 active principles and 84 pharmaceutical forms were included. Recommendations and instructions for oral, nasogastric tube, and gastrostomy administration, handling of the antineoplastic and immunomodulating drugs, and interactions with EN were described. Conclusions: the handling and administration information about the oral antineoplastic and immunomodulating drugs currently used in oncohematology for people with enteral accesses or swallowing disorders is limited. It is important to perform post-marketing studies to ensure a safe and effective administration of these drugs.

INTRODUCCIÓN: Introducción y objetivo: en los últimos años, el número de fármacos antineoplásicos e inmunomoduladores orales (ANIO) ha crecido enormemente. Con frecuencia, estos fármacos deben administrarse por sonda enteral (SE) o a pacientes con problemas de deglución, planteando un problema respecto a su manipulación (muchos pertenecen al grupo de medicamentos peligrosos). Además, también pueden presentar interacciones cuando se administran con la nutrición enteral (NE). El objetivo ha sido analizar y actualizar las recomendaciones de administración y manipulación de los ANIO. Métodos: se creó un Grupo de Trabajo formado por farmacéuticos del Grupo de Farmacia de la Sociedad Española de Nutrición Clínica y Metabolismo (SENPE) y del Grupo de Nutrición Clínica de la Sociedad Española de Farmacia Hospitalaria (SEFH). Se realizó una revisión bibliográfica entre 2015 y 2020 de las condiciones de manipulación y administración de los ANIO en oncohematología, elaborando una tabla que recoge especialidades farmacéuticas, dosis, presentación, nombre comercial, instrucciones para la administración oral y por SE, interacciones con la NE, precauciones y observaciones para su manipulación y administración. Resultados: se elaboró una tabla con 77 principios activos y 84 formas farmacéuticas, recogiendo recomendaciones e instrucciones para su administración por vía oral, sonda nasogástrica y gastrostomía, para la correcta manipulación y para la administración junto a la NE. Conclusiones: la información sobre cómo administrar y manipular los ANIO en personas con accesos enterales o problemas de deglución es escasa. Consideramos importante incluir en los estudios poscomercialización una investigación dirigida a responder a estas cuestiones para garantizar una administración segura y eficaz de los medicamentos a estos pacientes.

[Effect of pharmacologic treatment of the nutritional status of neurologic patients]. / Efecto del tratamiento farmacológico en el estado nutricional del paciente neurológico.

Clinical manifestations accompanying neurological diseases are diverse and affect multiple organs. Nutritional status of patients with certain neurological diseases such as stroke, Alzheimer's disease, Parkinson's disease, Epilepsy and Multiple Sclerosis can be altered because of symptoms associated with disease course, including certain micronutrient deficiency (folic acid, zinc, vitamin B6 and B12, vitamin D, vitamin E and vitamin C), changes in energy expenditure, intake decreased, gastrointestinal disorders and dysfunction of the bone mass. Also, we have to take in account other factors as: advanced age, multiple co morbidities, polypharmacy, the use of herbal products, social habits, diet and pharmacological treatments effect. An assessment of the factors related to neurological treatment that cause alterations in metabolic and nutritional status was performed: side effects of anti-Parkinson drugs, antiepileptic drugs, and multiple sclerosis drugs; drug-nutrient interactions; and nutrient-drug interactions.

[Pharmaceutical care strategies to prevent medication errors]. / Estrategias de atención farmacéutica para prevenir errores de medicación.

OBJECTIVE: To evaluate the impact of implementing new programs to improve the quality of the pharmaceutical care and unit-dose distribution system for in-patients. MATERIAL AND METHODS: An observational and prospective study was carried out in a general hospital during two different six-monthly period. Transcription and dispensation errors were evaluated in twelve wards during the first six months. Then, two new measures were introduced: the first- reference ward-pharmacist and the second-a new protocol for checking medication on the ward. Results were evaluated by SPSS v. 14 program. RESULTS: In the transcription evaluation, units without a ward pharmacist did not improve. Transcription errors significantly decreased in three units: gynaecology-urology (3.24% vs. 0.52%), orthopaedic (2% vs. 1.69%) and neurology-pneumology (2.81% vs. 2.02%). In dispensing, only units with the new protocol decreased their medication errors (1.77% vs. 1.24%). CONCLUSIONS: The participation of pharmacists in multidisciplinary teams and exhaustive protocols for dispensing medication were effective in detecting and decreasing medication errors in patients.
