RESUMO

BACKGROUND: Most patients with haematological malignancies who undergo allogeneic haematopoietic stem cell transplant (HSCT) receive chemotherapy before the transplant to control the disease. Certain chemotherapy drugs can cause lung toxicity. Conversely, in patients with chronic respiratory conditions, the 6-min walking test (6MWT) and the desaturation-distance ratio (DDR) have demonstrated prognostic significance. Our objective was to determine whether the 6MWD and DDR, assessed prior to HSCT, have a prognostic impact on survival at 24 months post-HSCT. METHODS: A prospective experimental study was conducted in consecutive patients referred for allogeneic HSCT at Hospital Clinic, Barcelona, Spain. A complete functional respiratory study, including the 6MWT and DDR, was conducted prior to admission. The area under the curve (AUC) and cut-off points were calculated. Data on patients' characteristics, HSCT details, main events, with a focus on lung complications, and survival at 24 months were analysed. RESULTS: One hundred and seventy-five patients (39% women) with mean age of 48 ± 13 years old were included. Before HSCT, forced vital capacity and forced expiratory volume in the first second were 96% ± 13% predicted and 92% ± 14% predicted, respectively; corrected diffusing capacity for carbon monoxide 79% ± 15% predicted; 6MWD was 568 ± 83 m and DDR of .27 (.20-.41). The cut-off points for 6MWD and DDR were 566 m, [.58 95% CI (.51-.64)], p = .024 and .306, [.63 95% CI (.55-.70)], p = .0005, respectively. The survival rate at 24 months was 55%. CONCLUSION: Our results showed that individuals who exhibit a 6MWD shorter than 566 ms or a decline in DDR beyond .306 experienced reduced survival rates at 24 months after HSCT.

RESUMO

BACKGROUND: Creating Vascular Access Teams (VAT) provides an expert nursing role that contributes to the training and continuous improvement of healthcare personnel. They can offer greater clinical safety, reducing complications and costs. Peripherally inserted central catheters (PICCs) and midline catheters (ML) can be safe and cost-effective alternatives to other types of venous access (VA). The aim of the study was to analyse our centre's VAT first 12 months of activity. The primary outcome was reported complications. Secondary outcomes were cause of catheter removal, consultancy activity and economic impact of VAT implantation. METHODOLOGY: A longitudinal, descriptive study was carried out from March 2019 to March 2020. Using consecutive sampling, all VA inserted, and all consults received were included. Patients under 18 years of age were excluded. RESULTS: The VAT inserted 1257 catheters into 1056 patients (291 MLs, 966 PICCs). The mean dwell time was 14.9 days for MLs and 59.07 days for PICCs. The main reason for removing VA was end of treatment (80.7%). During VA follow-up confirmed infection was detected in 1 ML (0.3%) and nine PICCs (0.9%). Symptomatic thrombosis was reported in 2 MLs (0.7%) and 16 PICCs (1.7%). The VAT received 367 consultations, and the main reason for consultation was to resolve doubts regarding the management of VA (80.9%). The insertion of ML and PICC catheters represented annual estimated economic savings of €867,688.44€. CONCLUSIONS: Our study provides a detailed analysis of VAT's activity, its relevance to clinical safety, and to efficient resource management within our hospital. It demonstrates how VAT establishment can be a safe and efficient intervention that enhances care quality.

RESUMO

OBJECTIVE: In recent years, safety concerns about modafinil exposure during pregnancy have emerged. In particular, increased risks for major congenital anomalies (MCA) and impaired fetal growth were reported, although study results were conflicting. Our investigation aims to examine previously reported safety signals. METHOD: Multicenter case series based on data from 18 Teratology Information Services from 12 countries. Modafinil exposed pregnancies with an estimated date of birth before August 2019 were included in this study. For prospectively ascertained pregnancies, cumulative incidences of pregnancy outcomes, rate of nonchromosomal MCA in first trimester exposed pregnancies and percentiles of neonatal/infant weight and head circumference (HC) were calculated. Potential dose-dependent effects on fetal growth were explored by linear regression models. Retrospectively ascertained cases were screened for pattern of MCA and other adverse events. RESULTS: One hundred and seventy-five prospectively ascertained cases were included, of which 173 were exposed at least during the first trimester. Cumulative incidences for live birth, spontaneous abortion and elective termination of pregnancy were 76.9% (95% CI, 68.0%-84.8%), 9.3% (95% CI, 5.0%-16.9%), and 13.9% (95% CI, 8.1%-23.1%), respectively. Nonchromosomal MCA was present in 3/150 live births, corresponding to an MCA rate of 2.0% (95%CI, 0.6%-6.1%), none were reported in pregnancy losses. Compared to reference standards, birth weight (BW) tended to be lower and neonatal HC to be smaller in exposed newborns (data available for 144 and 73 of 153 live births, respectively). In nonadjusted linear regression models, each 100 mg increase of average dosage per pregnancy day was associated with a decrease in standard deviation score (SDS) of -0.28 SDS (95% CI, -0.45 to -0.10) for BW and of -0.28 SDS (95% CI, -0.56 to 0.01) for HC. Screening of 22 retrospectively reported cases did not reveal any specific pattern of MCA or other adverse outcomes. CONCLUSION: The results do not indicate an increased risk of MCA after in utero exposure to modafinil, but a tendency toward lower BW and reduced neonatal HC. However, these findings should be regarded as preliminary. Until further studies allow for a definite conclusion, modafinil should not be used during pregnancy.

RESUMO

Personalized nutrition (PN) has gained much attention as a tool for empowerment of consumers to promote changes in dietary behavior, optimizing health status and preventing diet related diseases. Generalized implementation of PN faces different obstacles, one of the most relevant being metabolic characterization of the individual. Although omics technologies allow for assessment the dynamics of metabolism with unprecedented detail, its translatability as affordable and simple PN protocols is still difficult due to the complexity of metabolic regulation and to different technical and economical constrains. In this work, we propose a conceptual framework that considers the dysregulation of a few overarching processes, namely Carbohydrate metabolism, lipid metabolism, inflammation, oxidative stress and microbiota-derived metabolites, as the basis of the onset of several non-communicable diseases. These processes can be assessed and characterized by specific sets of proteomic, metabolomic and genetic markers that minimize operational constrains and maximize the information obtained at the individual level. Current machine learning and data analysis methodologies allow the development of algorithms to integrate omics and genetic markers. Reduction of dimensionality of variables facilitates the implementation of omics and genetic information in digital tools. This framework is exemplified by presenting the EU-Funded project PREVENTOMICS as a use case.

RESUMO

In the framework of the research project called fitomatics, we have isolated and characterized a bacterial plant-endophyte from the rhizomes of Iris germanica, hereafter referred to as strain FIT81T. The bacterium is Gram negative, rod-shaped with lophotrichous flagella, and catalase- and oxidase-positive. The optimal growth temperature of strain FIT81T is 28 °C, although it can grow within a temperature range of 4-32 °C. The pH growth tolerance ranges between pH 5 and 10, and it tolerates 4% (w/v) NaCl. A 16S rRNA phylogenetic analysis positioned strain FIT81T within the genus Pseudomonas, and multilocus sequence analysis revealed that Pseudomonas gozinkensis IzPS32dT, Pseudomonas glycinae MS586T, Pseudomonas allokribbensis IzPS23T, 'Pseudomonas kribbensis' 46-2 and Pseudomonas koreensis PS9-14T are the top five most closely related species, which were selected for further genome-to-genome comparisons, as well as for physiological and chemotaxonomic characterization. The genome size of strain FIT81T is 6 492 796 base-pairs long, with 60.6 mol% of G+C content. Average nucleotide identity and digital DNA-DNA hybridization analyses yielded values of 93.6 and 56.1%, respectively, when the FIT81T genome was compared to that of the closest type strain P. gozinkensis IzPS32dT. Taken together, the obtained genomic, physiologic and chemotaxonomic data indicate that strain FIT81T is different from its closest relative species, which lead us to suggest that it is a novel species to be included in the list of type strains with the name Pseudomonas fitomaticsae sp. nov. (FIT81T=CECT 30374T=DSM 112699T).

RESUMO

The emergency of the coronavirus disease 2019 (COVID-19) pandemic led to the off-label use of drugs without data on their toxicity profiles in patients with COVID-19, or on their concomitant use. Patients included in the COVID-19 Patient Registry of a tertiary hospital during the first wave were analyzed to evaluate the adverse drug reactions (ADRs) with the selected treatments. Twenty-one percent of patients (197 out of 933) had at least one ADR, with a total of 240 ADRs. Patients with ADRs were more commonly treated with multiple drugs for COVID-19 infection than patients without ADRs (p < 0.001). They were younger (median 62 years vs. 70.1 years; p < 0.001) and took less medication regularly (69.5% vs. 75.7%; p = 0.031). The most frequent ADRs were gastrointestinal (67.1%), hepatobiliary (10.8%), and cardiac disorders (3.3%). Drugs more frequently involved included lopinavir/ritonavir (82.2%), hydroxychloroquine (72.1%), and azithromycin (66.5%). Although most ADRs recovered without sequelae, fatal cases were described, even though the role of the disease could not be completely ruled out. In similar situations, efforts should be made to use the drugs in the context of clinical trials, and to limit off-label use to those drugs with a better benefit/risk profile in specific situations and for patients at high risk of poor disease prognosis.

RESUMO

AIM: To retrospectively analyse hospital outpatient treatment (HOT) withdrawal due to unacceptable toxicity at our hospital. Information regarding unacceptable toxicity leading to treatment withdrawal was recorded. METHODS: HOT interruptions because of unacceptable toxicity were identified from the Register of Patients and Treatments (RPT) (January 2014 to December 2017). Information regarding the demographic and clinical characteristics of patients, adverse drug reactions (ADRs) and drug treatments was retrieved from electronic health records. Causality and previous knowledge of ADRs were assessed according to the Spanish Pharmacovigilance System algorithm. Information regarding HOT risk management plans (RMPs) and their classification as inverted black triangle medicines was obtained from the European Medicines Agency (EMA). RESULTS: HOTs were withdrawn due to unacceptable toxicity in 136 (1.5%) registries corresponding to 135 (1.7%) patients. Fifty-one different HOTs (38.6% of those registered) were involved in 240 ADR/HOT pairs: 24 (47%) were additional monitoring medicines and 37 (72.5%) were EMA RMPs. The most frequent medicines involved in ADRs were lenalidomide (30, 12.5%) (mainly neutropenia, thrombocytopenia and bicytopenia), bevacizumab (19, 7.9%) (mainly venous and pulmonary thromboembolism) and sunitinib (13, 5.4%) (mainly thromboembolic events, diarrhoea and worsening of chronic renal failure). Cytopenia (40, 17.3%), diarrhoea (15, 6.5%), asthenia (9, 3.9%) and neuropathy (6, 2.6%) were the most frequent ADRs. All ADRs were severe, 10 (6 patients) had been poorly described or were unknown and only 9 (5 patients) had been reported by spontaneous notification. CONCLUSIONS: Valuable information regarding severe and unknown ADRs was obtained from the RPT. Such registers are useful tools to complement spontaneous ADR notifications.

RESUMO

La terapia celular CAR-T es una inmunoterapia personalizada de última generación. Se basa en la modificación genética de linfocitos T autólogos del paciente para expresar un antígeno quimérico que identifique a las células cancerosas y las destruya. El rápido progreso de nuevos tratamientos de inmunoterapia ha generado una oportunidad a las enfermeras para que aporten su experiencia y sus competencias para liderar y facilitar la coordinación, educación y continuidad de cuidados a los pacientes beneficiarios de estas terapias. La enfermera de práctica avanzada de hematología en terapia CAR-T (EPACAR-T) es esencial para garantizar la continuidad de cuidados y la seguridad en la atención a pacientes tratados con CAR-T. En el presente trabajo se describen las competencias de la EPACAR-T basadas en el marco conceptual de Hamric y se determinan sus funciones en las diferentes etapas del proceso (acogida y valoración, leucoaféresis, producción celular y terapia puente, tratamiento linfodeplectivo, infusión de linfocitos T modificados, seguimiento y vigilancia activa), con el objetivo principal de ofrecer un plan de cuidados centrados en la persona y coordinar la atención, colaboración y comunicación entre centros remitentes y proveedores y conseguir su manejo exitoso


The CAR T-cell therapy is a personalized last-generation immunotherapy. It consists in the genetic modification of the patient's autologous T-lymphocytes in order to express a chimeric antigen that will identify cancer cells and destroy them. The fast progress of new immunotherapy treatments has created an opportunity for nurses to provide their experience and skills to lead and ensure coordination, education, and continuity of care for patients who will benefit of said therapies. The Hematology Advanced Nurse Practitioner in CAR-T therapy is essential to ensure continuity and safety of care for patients treated with CAR-T. The present article describes the competencies of the Hematology Advanced Nurse Practitioner in CAR-T therapy based on the conceptual framework by Hamric, and determines their role in the different stages of the process (reception and assessment, leukapheresis, cell production and bridge therapy, lymphodepletion treatment, infusion of modified T-lymphocytes, follow-up and active monitoring), with the main objective to offer a plan of care focused on the patient, and coordinate the care, collaboration and communication between referring centers and providers, and achieve a successful management

RESUMO

Reusing by-products is an important strategy to ensure the preservation of natural capital and climate change mitigation. This study aimed at evaluating the potential of cork granulates, a by-product of winery industry, as an organic carbon (OC) source for the treatment of hydroponic wastewaters. First, chemical characterization was performed and discussed. Secondly, batch studies were performed using synthetic hydroponic wastewater to understand the role of particle size (PS), pH and contact time (CT) on the release of OC. The suberin is the major compound, representing >50%. It was noticed that a variance on the content of suberin across species, within the same species and depending on the extraction part (belly, cork and back) could be expected. >60% of the sample is composed by carbon while <1% was nitrogen (high C:N ratio), indicating a low risk of releasing organic nitrogen. The statistical results suggested that the main effect of PS on the release of OC is greater than both, CT and pH. The chemical release of OC gets slower with time, being this effect greater as the PS increase. Moreover, estimations showed that using the 4 mm PS, the amount of water treated would be twice the amount if the 8 mm PS had been used. The PS seems to play an important role at design nature-based solutions (NBS) focused on denitrification. The surface response methodology indicates a significant negative interaction between CT and PS suggesting that the mathematical model could be used for further optimization studies. The reuse of organic by-products as filter media seems to be an economic and environmentally friendly alternative to enhance denitrification in NBS, while preserving natural capital. However, further real scale and long-term experiments are needed to validate cork's potential as an "internal" OC source for NBS.

RESUMO

BACKGROUND: Evidence on the efficacy of smartphone applications (apps) for reducing body weight and other measurements of adiposity sustainably is not conclusive. OBJECTIVE: To evaluate the effect of adding an app for 3 months to traditional counselling on physical activity (PA) and a heart-healthy diet for the modification of measurements of adiposity at 3 and 12 months after intervention. METHODS: This randomised clinical trial included 833 subjects. The counselling and app group (IG) had 415 subjects, while 418 were included in the counselling only group (CG). The primary outcome was adiposity measurements at 3 and 12 months after intervention. The secondary outcome was the effect of the intervention by sex. INTERVENTION: Counselling on a heart-healthy diet and PA was given to both groups. The IG also received training in the use of a smartphone app designed to promote a heart-healthy diet and PA, and this group was given access to this application for 3 months. Outcome measurements included waist circumference (WC), body mass index (BMI) and Clínica Universidad de Navarra - body adiposity estimator (CUN-BAE). RESULTS: In the IG at 12 months, the following decreased: WC -0.72 cm (95% confidence interval [CI]: -2.35 to -0.02) and CUN-BAE -0.35 (95% CI: -0.63 to -0.06). These decreases were only observed in women. After baseline adjustment, the beneficial effect was maintained in the IG compared to the CG at 12 months in terms of WC (-0.67; 95% CI: -0.29 to -0.02) and CUN-BAE (-0.57; 95% CI: -1.10 to -0.04), but only in women. CONCLUSIONS: An intervention of nutritional counselling and PA plus the smartphone app with personalised recommendations compared to CG showed beneficial results in terms of reduction of abdominal obesity and the percentage of body fat in women, but not in men.

RESUMO

BACKGROUND: Extravasation of chemotherapy is an undesirable complication related to the administration of antineoplastic therapy. Establishing the real incidence is difficult. Because of the importance of a quick intervention after an extravasation, every hospital should have an extravasation protocol. OBJECTIVES: The purpose of this study was to determine the degree of observance of an extravasation protocol by nursing staff and to determine extravasation incidence. METHODS: This descriptive, longitudinal, retrospective study was set in a tertiary-level hospital. The researchers reviewed 117 extravasation notification forms received by the pharmacy department during a 10-year period. Nursing actuation, particularly observance of the extravasation protocol, was analyzed. FINDINGS: Protocol adherence was 89%. Twelve deviations from the protocol in the application of recommended measures were detected. An antidote was used in 41 patients, and temperature measures were applied in 14 cases. Ninety-nine patients had at least one episode of reported follow-up. No cases of necrosis or skin ulcers were described, except by one patient, who developed a delayed skin ulcer to vinorelbine. Drugs most frequently reported were etoposide, carboplatin, and paclitaxel. Nursing staff should be continuously trained in extravasation protocol because a rapid actuation can prevent skin lesions.

RESUMO

BACKGROUND: Hypercholesterolaemia plays a key role in the development and progression of coronary artery disease. There are numerous drugs available to treat this condition but they are often expensive and can have unwanted side effects. Therefore, a screening of lactic acid bacteria to select candidate probiotic strains to reduce cholesterol levels was carried out. Three Lactobacillus plantarum strains (CECT 7527, 7528 and 7529) were selected as potential probiotics to reduce cholesterol levels after conducting several in vitro tests for demonstrating the functionalities of the strains according to international guidelines. RESULTS: The three strains showed a high ability to survive under gastrointestinal tract conditions and to adhere to intestinal cells. Regarding lipid metabolism, the strains showed a great production of bile salt hydrolase, especially when combined. Moreover, the strains assimilated cholesterol directly from the medium. Part of the cholesterol present in the medium was removed via binding onto the bacterial cellular surface. Finally, the three strains, especially CECT 7529, produce large quantities of propionic and butyric acids. CONCLUSION: Combined, these characteristics suggest that these strains could be excellent candidates for reducing high blood cholesterol levels.

RESUMO

BACKGROUND: We conducted a study to explore the relationship between television viewing time and central hemodynamic parameters and the radial augmentation index (AIx) in adults. METHODS: Random sampling was used to select 732 individuals who attended primary-care centers as subjects for the study. The self-reported time that these individuals spent in viewing television was elicited with a questionnaire and included the number of hours that they spent watching television while sitting or lying down. The subjects' physical activity was estimated through accelerometers attached to their waists. Central hemodynamic parameters and the peripheral augmentation index adjusted for a heart rate of 75 bpm (PAIx75) were measured with pulse-wave application software (A-Pulse CASP). RESULTS: The subjects' systolic blood pressure (SBP) (central and peripheral), pulse pressure, and radial AIx showed significant differences between tertiles of television viewing time, with the lowest values in the first tertile (P < 0.01). After adjustment for age and sex, a multiple linear regression analysis showed an association of television viewing time with office SBP. Although the association of television viewing time with central SBP followed the same trend as for office BP, it did not reach statistical significance. After adjustment for age, sex, waist-to-height ratio, physical activity reflected by accelerometer data (counts/min), high-density lipoprotein cholesterol, smoking, antihypertensive and antidiabetic medication, and the use of lipid-lowering drugs, an increase in PAIx75 of 0.22 was estimated for each hour of increase in television viewing time (P < 0.01). CONCLUSIONS: Television viewing time was directly correlated with PAIx75 in an adult population. This correlation was maintained even after adjustment for physical activity, age, sex, and other cardiovascular risk factors.

RESUMO

Objetivo: El Brief Physical Activity Assessment Tool (BPAAT) y General Practice Physical Activity Questionnaire (GPPAQ) son instrumentos breves y válidos para identificar pacientes «físicamente inactivos» en consulta. Este estudio evalúa la fiabilidad y validez de su versión catalana (CBPAAT-CGPPAQ) y española (CBPAAT-EGPPAQ) ante la inexistencia de instrumentos similares validados en nuestro medio. Diseño: Evaluación psicométrica de la adaptación cultural y lingüística al catalán/español de 2 instrumentos de medida. Emplazamiento: centros de atención primaria. Participantes: La carga de administración de los cuestionarios se evaluó en 7 profesionales sanitarios y 44 pacientes. Su validez de constructo y fiabilidad test-retest se evaluó en 105 pacientes (58 años±20; 37% hombres) sin contraindicaciones para hacer actividad física (AF). Mediciones principales: Después de efectuar la traducción directa e inversa, la validez de constructo midió el grado de acuerdo de dichas versiones con el Cuestionario Internacional de AF (IPAQ) versión corta. La fiabilidad test-retest se evaluó repitiendo el cuestionario en un intervalo de 14-28 días. Resultados: El CBPAAT-EBPAAT mostró un grado de acuerdo moderado con el IPAQ coincidiendo en un 80 y 83% de los casos «inactivos». Presentaron una buena fiabilidad test-retest, coincidiendo en un 86 y un 88% de la clasificación. El CGPPAQ-EGPPAQ mostró un grado de acuerdo moderado con el IPAQ, coincidiendo en un 70 y 60% de los casos «inactivos». Presentaron una buena fiabilidad test-retest, coincidiendo en la clasificación de un 82 y 72% de los casos. Conclusiones: El CBPAAT-CGPPAQ y EBPAAT-EGPPAQ presentan una validez aceptable para identificar en consulta a pacientes físicamente inactivos(AU)


Objective: The Brief Physical Activity Assessment Tool (BPAAT) and the General Practice Physical Activity Questionnaire (GPPAQ) are valid and reliable assessment tools to identify "inactive" patients in primary care. No similar tools exist for the Spanish population. The study aimed to evaluate the reliability and validity of the Catalan and Spanish versions (CBPAAT-CGPPAQ; CBPAAT-EGPPAQ) of such tools. Design: Validation study of the linguistic and cultural adaptation of two questionnaires into Catalan/Spanish. Setting: Centres of Primary Care. Participants: The load for administering the questionnaires was evaluated by 7 general practitioners and 44 patients. Construct validity and reliability was assessed in 105 patients (58 years old±20; 37% men) without any contraindication for physical activity (PA). Main variables: After carrying out the translation and back-translation, construct validity was assessed against the International Physical Activity Questionnaire (IPAQ short form). Reliability was assessed administering the questionnaires again within 14 to 28 days. Results: The validity of the CBPAAT-EBPAAT showed a moderate percentage agreement, correctly classifying over 80% and 83% of the "inactive" cases. Reliability was also good, correctly classifying over 86% and 88% of the cases. The validity of the CGPPAQ-EGPPAQ showed a moderate percentage agreement, correctly classifying over 70% and 60% of the "inactive" cases. Reliability was good, correctly classifying over 82% and 72% of the cases. Conclusions: The CBPAAT-CGPPAQ and EBPAAT-EGPPAQ are valid instruments to identify "inactive" patients that should receive advice on PA(AU)
