RESUMO

Introducción: Guía para la práctica clínica en neurorrehabilitación de personas adultas con daño cerebral adquirido de la Sociedad Española de Neurorrehabilitación. Documento basado en la revisión de guías de práctica clínica internacionales publicadas entre 2013-2020. Desarrollo: Se establecen recomendaciones según el nivel de evidencia que ofrecen los estudios revisados referentes a aspectos consensuados entre expertos dirigidos a definir la población, características específicas de la intervención o la exposición bajo investigación. Conclusiones: Deben recibir neurorrehabilitación todos aquellos pacientes que, tras un daño cerebral adquirido, hayan alcanzado una mínima estabilidad clínica. La neurorrehabilitación debe ofrecer tanto tratamiento como sea posible en términos de frecuencia, duración e intensidad (al menos 45-60 minutos de cada modalidad de terapia específica que el paciente precise). La neurorrehabilitación requiere un equipo transdisciplinar coordinado, con el conocimiento, la experiencia y las habilidades para trabajar en equipo tanto con pacientes como con sus familias. En la fase aguda, y para los casos más graves, se recomiendan programas de rehabilitación en unidades hospitalarias, procediéndose a tratamiento ambulatorio tan pronto como la situación clínica lo permita y se puedan mantener los criterios de intensidad. La duración del tratamiento debe basarse en la respuesta terapéutica y en las posibilidades de mejoría, en función del mayor grado de evidencia disponible. Al alta deben ofrecerse servicios de promoción de la salud, actividad física, apoyo y seguimiento para garantizar que se mantengan los beneficios alcanzados, detectar posibles complicaciones o valorar posibles cambios en la funcionalidad que hagan necesario el acceso a nuevos programas de tratamiento.(AU)


Introduction: We present the Spanish Society of Neurorehabilitation's guidelines for adult acquired brain injury (ABI) rehabilitation. These recommendations are based on a review of international clinical practice guidelines published between 2013 and 2020. Development: We establish recommendations based on the levels of evidence of the studies reviewed and expert consensus on population characteristics and the specific aspects of the intervention or procedure under research. Conclusions: All patients with ABI should receive neurorehabilitation therapy once they present a minimal level of clinical stability. Neurorehabilitation should offer as much treatment as possible in terms of frequency, duration, and intensity (at least 45–60 min of each specific form of therapy that is needed). Neurorehabilitation requires a coordinated, multidisciplinary team with the knowledge, experience, and skills needed to work in collaboration both with patients and with their families. Inpatient rehabilitation interventions are recommended for patients with more severe deficits and those in the acute phase, with outpatient treatment to be offered as soon as the patient's clinical situation allows it, as long as intensity criteria can be maintained. The duration of treatment should be based on treatment response and the possibilities for further improvement, according to the best available evidence. At discharge, patients should be offered health promotion, physical activity, support, and follow-up services to ensure that the benefits achieved are maintained, to detect possible complications, and to assess possible changes in functional status that may lead the patient to need other treatment programmes.(AU)

RESUMO

BACKGROUND: Intravenous artesunate (AS) is the first-line treatment for patients with severe imported malaria (SIM) worldwide. However, after 10 years of use in France, AS hasn't yet received marketing authorization.The purpose of this study was to assess the real-life effectiveness and safety of AS in the treatment of SIM in two Hospitals in France. METHODS: We performed a bicenter retrospective and observational study. All patients treated with AS for SIM between 2014 and 2018 and 2016-2020 were included. The effectiveness of AS was evaluated by parasite clearance, number of deaths, and the length of hospital stay. The real-life safety was assessed by related adverse events (AE) and monitoring of biological blood parameters during the hospital stay and follow-up period. RESULTS: 110 patients were included during the six-year study period. 71.8% of patients were parasite-negative of their day 3 thick and thin blood smears after AS treatment. No patients discontinued AS due to an AE and no serious AE were declared. Two cases of delayed post-artesunate hemolysis occurred and required blood transfusions. CONCLUSION: This study highlights effectiveness and safety of AS in non-endemic areas. Administrative procedures must be accelerated in order to obtain full registration and facilitate access to AS in France.

RESUMO

Mujer de 56 años que arrastra problemas de salud neurológicos desde 2017 tras sufrir un accidente de tráfico. Le diagnostican un parkinsonismo. En noviembre de 2021 acude a consultar información sobre los cribados de deterioro cognitivo desde la farmacia comunitaria al presentar queja de olvidos frecuentes. Finalmente, en junio de 2022 se lleva a cabo una evaluación farmacoterapéutica del tratamiento siguiendo la metodología Dáder y se estudia la carga anticolinérgica (CA) que presenta la medicación. Según la escala CALS, la paciente presentó una CA de 3,25 que se puede relacionar con aparición de efectos adversos como alteraciones de la cognición. Al no tener controlado el dolor, se le sugiere volver a consultar con su médico para intentar lograr un tratamiento efectivo. Con la nueva visita se diagnostica un trastorno neurológico funcional y trastorno depresivo mayor. Con el cambio de tratamiento, la CA disminuyó hasta 1. El tratamiento del dolor neuropático es complejo y el diagnóstico certero es importante para instaurar el tratamiento efectivo. Aunque muchas veces la sintomatología conlleva a confundir el diagnóstico y tratar con fármacos no eficaces para solucionar el problema que causan reacciones adversas como es el caso. En estas situaciones es necesario una reevaluación periódica del tratamiento y del estado cognitivo del paciente (AU)

RESUMO

Octopus vulgaris (Cuvier, 1797) is a cephalopod species with great economic value. In western Asturias (northwest of Spain), O. vulgaris artisanal fisheries are relatively well monitored and conditionally eco-labeled by the Marine Stewardship Council (MSC). Despite this, the Asturian octopus stocks have not been genetically assessed so far. In order to improve the current fishery plan and contrast the octopus eco-label validity in Asturias, 539 individuals from five regions of the O. vulgaris geographic distribution, including temporal samplings in Asturias, were collected and genotyped at thirteen microsatellite loci. All the samples under analysis were in agreement with Hardy-Weinberg expectations. Spatial levels of genetic differentiation were estimated using F-statistics, multidimensional scaling, and Bayesian analyses. Results suggested that the O. vulgaris consists of at least four genetically different stocks coming from two ancestral lineages. In addition, temporal analyses showed stability in terms of genetic variation and high NE (> 50) for several generations in different localities within Asturias, pointing out to indeed sustainable fishery exploitation levels. Even though, the current Asturias fishery plan shows no significant genetic damages to the stocks, the regional-specific management plans need systematic genetic monitoring schemes as part of an efficient and preventive regional fishery regulation strategy.

RESUMO

Introduction: A challenge when applying an artificial intelligence (AI) deep learning (DL) approach to novel electroencephalography (EEG) data, is the DL architecture's lack of adaptability to changing numbers of EEG channels. That is, the number of channels cannot vary neither in the training data, nor upon deployment. Such highly specific hardware constraints put major limitations on the clinical usability and scalability of the DL models. Methods: In this work, we propose a technique for handling such varied numbers of EEG channels by splitting the EEG montages into distinct regions and merge the channels within the same region to a region representation. The solution is termed Region Based Pooling (RBP). The procedure of splitting the montage into regions is performed repeatedly with different region configurations, to minimize potential loss of information. As RBP maps a varied number of EEG channels to a fixed number of region representations, both current and future DL architectures may apply RBP with ease. To demonstrate and evaluate the adequacy of RBP to handle a varied number of EEG channels, sex classification based solely on EEG was used as a test example. The DL models were trained on 129 channels, and tested on 32, 65, and 129-channels versions of the data using the same channel positions scheme. The baselines for comparison were zero-filling the missing channels and applying spherical spline interpolation. The performances were estimated using 5-fold cross validation. Results: For the 32-channel system version, the mean AUC values across the folds were: RBP (93.34%), spherical spline interpolation (93.36%), and zero-filling (76.82%). Similarly, on the 65-channel system version, the performances were: RBP (93.66%), spherical spline interpolation (93.50%), and zero-filling (85.58%). Finally, the 129-channel system version produced the following results: RBP (94.68%), spherical spline interpolation (93.86%), and zero-filling (91.92%). Conclusion: In conclusion, RBP obtained similar results to spherical spline interpolation, and superior results to zero-filling. We encourage further research and development of DL models in the cross-dataset setting, including the use of methods such as RBP and spherical spline interpolation to handle a varied number of EEG channels.

RESUMO

Introducción: La valoración que el paciente hace de la atención prestada es un indicador importante de la calidad del servicio prestado, demostrando ser eficaz en la mejora continua de la calidad asistencial a fin de detectar debilidades que ayuden a desarrollar estrategias de mejora. Uno de esos medidores es el Net Promoter Score (NPS), sistema de medición que indica la probabilidad que se recomiende el servicio a un familiar o amigo. En mayo de 2021 comenzó una prueba piloto con la cual se impulsa un proceso de automatización del sistema de evaluación de la satisfacción del paciente. El objetivo de este estudio es obtener una valoración cuantificable de la satisfacción de nuestros pacientes, conociendo el NPS de nuestra unidad. Metodología: Se realizó un estudio retrospectivo de los datos obtenidos a través de las encuestas realizadas digitalmente por los pacientes en un periodo comprendido desde el 21 de mayo de 2021 al 31 de marzo de 2022. Resultados: La satisfacción global ha sido muy alta, estando el 95,4 % de los pacientes feliz. Se obtuvo un NPS de 87, lo que sitúa a nuestra unidad en datos de excelencia. Conclusiones: Las herramientas cuantitativas de medición ayudan a mantener una monitorización continua de los estándares de calidad para identificar problemas, corregirlos y/o prevenirlos. Las encuestas informatizadas deben ser eficientes, de fácil desarrollo y efectuadas con regularidad (AU)


Introduction: The patient’s evaluation of the care provided is an important indicator of the quality of the service offered, proving to be effective in the continuous improvement of the quality of care, in order to detect weaknesses that help to develop strategies for improvement. One such measure is the Net Promoter Score (NPS), a system of measurement that indicates the probability that the service will be recommended to a family member or friend. In May 2021, a pilot test will begin to drive a process of automation of the patient satisfaction evaluation system. The aim of this study is to obtain a quantifiable assessment of the satisfaction of our patients, knowing the NPS of our department. Methodology: A retrospective study was carried out of the data obtained from the surveys carried out digitally by patients in the period from 21 May 2021 to 31 March 2022. Results: Overall satisfaction was very high, with 95.4% of patients being happy, and an NPS of 87 was obtained, which places our department in a position of excellence. Conclusions: Quantitative measurement tools help to keep a continuous monitoring of quality standards in order to identify problems, correct them and/or prevent them. Computerised surveys must be efficient, easy to develop and carried out regularly (AU)

RESUMO

Amoebae from the genus Acanthamoeba are important pathogens responsible for severe illnesses in humans such as Acanthamoeba keratitis and granulomatous amoebic encephalitis. In the last few decades, AK diagnoses have steadily increased. Most patients suffering from AK were contact lens users and the infection was related to poor hygiene. However, therapy is not yet well established, and treatments may last for several months due to resistance. Moreover, these treatments have been described to generate cytotoxicity. Therefore, there is an urgent need to develop new therapeutic strategies against AK. In this study, the amoebicidal activity of different generation cationic carbosilane dendrons derived with 4-phenylbutyric acid was demonstrated against Acanthamoeba polyphaga and Acanthamoeba griffini trophozoites and cysts. In addition, the combination of chlorhexidine digluconate and the most effective dendron (ArCO2G2(SNMe3I)4) showed an in vitro effect against Acanthamoeba trophozoites and cysts, reducing the minimal trophozoite amoebicidal concentration as well as concentrations with cysticidal activity.

RESUMO

Post-radiation diaphragmatic weakness have rarely been described. We report two cases of post-radiation diaphragmatic weakness from our center, and review the other published cases, computing clinical, electromyography and magnetic resonance imaging data. Including our two cases, seven cases of post-radiation diaphragmatic weakness have been described. Most occurred after mantle-field radiotherapy for Hodgkin lymphoma (5/7), often in associations with chemotherapy (4/7). Other radiations-induced complications were found (5/7) such as brachial plexopathy, cardiac involvement or hypothyroidy. When studied, phrenic nerve conduction studies revealed different profiles, from clearly abnormal responses to limit amplitudes. Imaging can be a useful diagnostic tool, displaying abnormalities with sharp limits matching the radiation field. Data is limited about long-term evolution. Presentation of post-radiation diaphragmatic weakness seems relatively homogeneous. We propose a diagnosis work-up for post-radiation diaphragmatic weakness, to exclude potentially treatable differential diagnoses.

RESUMO

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive diaphragm weakness and deteriorating lung function. Bulbar involvement and cough weakness contribute to respiratory morbidity and mortality. ALS-related respiratory failure significantly affects quality of life and is the leading cause of death. Non-invasive ventilation (NIV), which is the main recognized treatment for alleviating the symptoms of respiratory failure, prolongs survival and improves quality of life. However, the optimal timing for the initiation of NIV is still a matter of debate. NIV is a complex intervention. Multiple factors influence the efficacy of NIV and patient adherence. The aim of this work was to develop practical evidence-based advices to standardize the respiratory care of ALS patients in French tertiary care centres. METHODS: For each proposal, a French expert panel systematically searched an indexed bibliography and prepared a written literature review that was then shared and discussed. A combined draft was prepared by the chairman for further discussion. All of the proposals were unanimously approved by the expert panel. RESULTS: The French expert panel updated the criteria for initiating NIV in ALS patients. The most recent criteria were established in 2005. Practical advice for NIV initiation were included and the value of each tool available for NIV monitoring was reviewed. A strategy to optimize NIV parameters was suggested. Revisions were also suggested for the use of mechanically assisted cough devices in ALS patients. CONCLUSION: Our French expert panel proposes an evidence-based review to update the respiratory care recommendations for ALS patients in daily practice.

RESUMO

There is a lack of evidence evaluating cryoprecipitate transfusion in severe postpartum haemorrhage. We performed a pilot cluster-randomised controlled trial to evaluate the feasibility of a trial on early cryoprecipitate delivery in severe postpartum haemorrhage. Pregnant women (>24 weeks gestation), actively bleeding within 24 h of delivery and who required at least one unit of red blood cells were eligible. Women declining transfusion in advance or with inherited clotting deficiencies were not eligible. Four UK hospitals were randomly allocated to deliver either the intervention (administration of two pools of cryoprecipitate within 90 min of first red blood cell unit requested plus standard care), or the control group treatment (standard care, where cryoprecipitate is administered later or not at all). The primary outcome was the proportion of women who received early cryoprecipitate (intervention) vs. standard care (control). Secondary outcomes included consent rates, acceptability of the intervention, safety outcomes and preliminary clinical outcome data to inform a definitive trial. Between March 2019 and January 2020, 199 participants were recruited; 19 refused consent, leaving 180 for analysis (110 in the intervention and 70 in the control group). Adherence to assigned treatment was 32% (95%CI 23-41%) in the intervention group vs. 81% (95%CI 70-90%) in the control group. The proportion of women receiving cryoprecipitate at any time-point was higher in the intervention (60%) vs. control (31%) groups; the former had fewer red blood cell transfusions at 24 h (mean difference -0.6 units, 95%CI -1.2 to 0); overall surgical procedures (odds ratio 0.6, 95%CI 0.3-1.1); and intensive care admissions (odds ratio 0.4, 95%CI 0.1-1.1). There was no increase in serious adverse or thrombotic events in the intervention group. Staff interviews showed that lack of awareness and uncertainty about study responsibilities contributed to lower adherence in the intervention group. We conclude that a full-scale trial may be feasible, provided that protocol revisions are put in place to establish clear lines of communication for ordering early cryoprecipitate in order to improve adherence. Preliminary clinical outcomes associated with cryoprecipitate administration are encouraging and merit further investigation.

RESUMO

Los quistes subglóticos adquiridos son una causa rara de estridor en la infancia, cuyo reporte ha ido en aumento en las últimas décadas. Su aparición se relaciona con la prematurez y la intubación en el periodo neonatal. Histológicamente, se observa una obstrucción de las glándulas mucosas de la subglotis debido una metaplasia escamosa del epitelio respiratorio. Esta es una condición que usualmente requiere de un alto índice de sospecha para llegar al diagnóstico, ya que pueden confundirse con otras patologías como laringitis aguda (croup), laringomalacia o asma. La nasofibroscopía permite sospechar su presencia, pero el gold standard diagnóstico lo constituye la laringo-tra-queo-broncoscopía directa en pabellón. Existen diversas técnicas para su manejo, siendo las más frecuentemente utilizadas la marsupialización con instrumental frío y láser. La recurrencia es frecuente, por lo que algunos autores han utilizado mitomicina C y la terapia antirreflujo para intentar disminuirla. Sin embargo, hasta la fecha falta evidencia de calidad que permita llegar a un consenso respecto al manejo ideal de esta patología. En este trabajo, presentamos tres casos clínico de pacientes con antecedentes de prematurez que fueron diagnosticados con quistes subglóticos adquiridos y manejados en un hospital pediátrico de alta complejidad.


Acquired subglottic cysts are an infrequent cause of stridor in infants, which has been increasingly reported in the last decades. Its appearance is related to prematurity and intubation in the neonatal period. Histologically, findings are characterized by an obstruction of the mucosal glands, due to squamous metaplasia of the respiratory epithelium. This condition usually requires a high index of suspicion to be diagnosed, as it can be misdiagnosed as croup, laryngomalacia or asthma. Flexible nasendoscopy allows an initial exploration of the larynx, but direct laryngo-tracheo-bronchoscopy in the operating room is the diagnostic gold standard. There are several techniques for its management, but the most frequently used are cold-steel marsupialization and laser. Recurrence is common, and some authors have used mitomycin C and antireflux therapy to try to decrease it. However, up to date, there is a lack of high-quality evidence, regarding the ideal management of this pathology, which prevents reaching a consensus. In this article, we present three clinical cases of premature patients who were diagnosed with subglottic cysts, treated in a tertiary pediatric hospital.

RESUMO

Soils play a critical role in the production of food and feed for a growing global population. Here, we review global patterns in soil characteristics, agricultural production and the fate of embedded soil nutrients. Nitrogen- and organic-rich soils supported the highest crop yields, yet the efficiency of nutrient utilization was concentrated in regions with lower crop productivity and lower rates of chemical fertilizer inputs. Globally, soil resources were concentrated in animal feed, resulting in large inefficiencies in nutrient utilization and losses from the food system. Intercontinental transport of soil-derived nutrients displaced millions of tonnes of nitrogen and phosphorus annually, much of which was ultimately concentrated in urban waste streams. Approximately 40% of the global agricultural land area was in small farms providing over 50% of the world's food and feed needs but yield gaps and economic constraints limit the ability to intensify production on these lands. To better use and protect soil resources in the global food system, policies and actions should encourage shifts to more nutrient-efficient diets, strategic intensification and technological improvement, restoration and maintenance of soil fertility and stability, and enhanced resilience in the face of global change. This article is part of the theme issue 'The role of soils in delivering Nature's Contributions to People'.
