Prevalence and prognostic meaning of interstitial lung abnormalities in remote CT scans of patients with interstitial lung disease treated with antifibrotic therapy.

OBJECTIVES: To describe the prevalence and characteristics of interstitial lung abnormalities (ILA) in CT scans performed prior to the initiation of antifibrotics in a series of patients with interstitial lung disease (ILD), and to identify characteristics apparent on early CT scans that could help to predict outcomes. METHODS: We conducted a retrospective observational study. The original cohort consisted of 101 patients diagnosed with ILD and treated with antifibrotics in a tertiary hospital. Patients were included if they had a thoracic CT scan performed at least one year before initiation of therapy. They were classified radiologically in three groups: without ILA, with radiological ILA and extensive abnormalities. ILA were classified as subpleural fibrotic, subpleural non-fibrotic and non-subpleural. The initial scan and the latest CT scan performed before treatment were read for assessing progression. The relationship between CT findings of fibrosis and the radiological progression rate and mortality were analyzed. RESULTS: We included 50 patients. Only 1 (2%) had a normal CT scan, 25 (50%) had extensive alterations and 24 (48%) had radiological criteria for ILA, a median of 98.2 months before initiation of antifibrotics, of them 18 (75%) had a subpleural fibrotic pattern. Significant bronchiectasis and obvious honeycombing in the lower zones were associated with shorter survival (p = 0.04). Obvious honeycombing in the lower zones was also significantly (p < 0.05) associated with a faster progression rate. CONCLUSIONS: Fibrotic ILAs are frequent in remote scans of patients with clinically relevant ILD, long before they require antifibrotics. Findings of traction bronchiectasis and honeycombing in the earliest scans, even in asymptomatic patients, are related to mortality and progression later on.

The longitudinal behavioral effects of acute exposure to galactic cosmic radiation in female C57BL/6J mice: implications for deep space missions, female crews, and potential antioxidant countermeasures.

Galactic cosmic radiation (GCR) is an unavoidable risk to astronauts that may affect mission success. Male rodents exposed to 33-beam-GCR (33-GCR) show short-term cognitive deficits but reports on female rodents and long-term assessment is lacking. Here we asked: What are the longitudinal behavioral effects of 33-GCR on female mice? Also, can an antioxidant/anti-inflammatory compound mitigate the impact of 33-GCR? Mature (6-month-old) C57BL/6J female mice received the antioxidant CDDO-EA (400 µg/g of food) or a control diet (vehicle, Veh) for 5 days and either Sham-irradiation (IRR) or whole-body 33-GCR (0.75Gy) on the 4th day. Three-months post-IRR, mice underwent two touchscreen-platform tests: 1) location discrimination reversal (which tests behavior pattern separation and cognitive flexibility, two abilities reliant on the dentate gyrus) and 2) stimulus-response learning/extinction. Mice then underwent arena-based behavior tests (e.g. open field, 3-chamber social interaction). At the experiment end (14.25-month post-IRR), neurogenesis was assessed (doublecortin-immunoreactive [DCX+] dentate gyrus neurons). Female mice exposed to Veh/Sham vs. Veh/33-GCR had similar pattern separation (% correct to 1st reversal). There were two effects of diet: CDDO-EA/Sham and CDDO-EA/33-GCR mice had better pattern separation vs. their respective control groups (Veh/Sham, Veh/33-GCR), and CDDO-EA/33-GCR mice had better cognitive flexibility (reversal number) vs. Veh/33-GCR mice. Notably, one radiation effect/CDDO-EA countereffect also emerged: Veh/33-GCR mice had worse stimulus-response learning (days to completion) vs. all other groups, including CDDO-EA/33-GCR mice. In general, all mice show normal anxiety-like behavior, exploration, and habituation to novel environments. There was also a change in neurogenesis: Veh/33-GCR mice had fewer DCX+ dentate gyrus immature neurons vs. Veh/Sham mice. Our study implies space radiation is a risk to a female crew's longitudinal mission-relevant cognitive processes and CDDO-EA is a potential dietary countermeasure for space-radiation CNS risks.

Development of a Questionnaire on Knowledge, Habits, and Attitudes on Sexually Transmitted Infections in Teenagers and Young Adults / Generación de un cuestionario sobre conocimientos, hábitos y actitudes sobre infecciones de transmisión sexual en adolescentes y adultos jóvenes

Communication with teenagers who are significantly affected by sexually transmitted infections (STIs) is essential for the sake of prevention. The aim of this study is to develop a specific questionnaire for surveying the degree of knowledge, behavior, and attitudes of current teenagers and young adults on STIs to come up with the proper training tools. We conducted the study following the Delphi method, a 2-round critical assessment score (from 1 to 9) of all domains and items. Only domains and items with median scores ≥8 were selected. A total of 8 panelists were involved in this survey. After establishing a median score ≥8, a total of 14 domains and 40 items were eventually selected. This is the first questionnaire ever conducted to study the knowledge, habits, and attitudes of contemporary teenagers and young adults on STIs, and stands as a valuable tool for future training on STI prevention in teenagers and young adults.

Modulation of myeloid-derived suppressor cell functions by oral inflammatory diseases and important oral pathogens.

The oral cavity presents a diverse microbiota in a dynamic balance with the host. Disruption of the microbial community can promote dysregulation of local immune response which could generate oral diseases. Additionally, alterations in host immune system can result in inflammatory disorders. Different microorganisms have been associated with establishment and progression of the oral diseases. Oral cavity pathogens/diseases can modulate components of the inflammatory response. Myeloid-derived suppressor cells (MDSCs) own immunoregulatory functions and have been involved in different inflammatory conditions such as infectious processes, autoimmune diseases, and cancer. The aim of this review is to provide a comprehensive overview of generation, phenotypes, and biological functions of the MDSCs in oral inflammatory diseases. Also, it is addressed the biological aspects of MDSCs in presence of major oral pathogens. MDSCs have been mainly analyzed in periodontal disease and Sjögren's syndrome and could be involved in the outcome of these diseases. Studies including the participation of MDSCs in other important oral diseases are very scarce. Major oral bacterial and fungal pathogens can modulate expansion, subpopulations, recruitment, metabolism, immunosuppressive activity and osteoclastogenic potential of MDSCs. Moreover, MDSC plasticity is exhibited in presence of oral inflammatory diseases/oral pathogens and appears to be relevant in the disease progression and potentially useful in the searching of possible treatments. Further analyses of MDSCs in oral cavity context could allow to understand the contribution of these cells in the fine-tuned balance between host immune system and microorganism of the oral biofilm, as well as their involvement in the development of oral diseases when this balance is altered.

Organophosphate ester additives and microplastics in benthic compartments from the Loire estuary (French Atlantic coast).

We report the first empirical confirmation of the co-occurrence of organophosphate esters (OPEs) additives and microplastics (MPs) in benthic compartments from the Loire estuary. Higher median concentrations of MPs (3387 items/kg dw), ∑13tri-OPEs (12.0 ng/g dw) and ∑4di-OPEs (0.7 ng/g dw) were measured in intertidal sediments with predominance of fine particles, and under higher anthropogenic pressures, with a general lack of seasonality. Contrarily, Scrobicularia plana showed up to 4-fold higher ∑tri-OPE concentrations in summer (reaching 37.0 ng/g dw), and similar spatial distribution. Polyethylene predominated in both compartments. Tris(2-ethylhexyl) phosphate (TEHP), its degradation metabolite (BEHP) and tris-(2-chloro, 1-methylethyl) phosphate (TCIPP) were the most abundant OPEs in sediments, while TCIPP predominated in S. plana. The biota-sediment accumulation factors suggest bioaccumulation potential for chlorinated-OPEs, with higher exposure in summer. No significant correlations were generally found between OPEs and MPs in sediments suggesting a limited role of MPs as in-situ source of OPEs.

Analysis of the competitive demands in 7-a-side football players with cerebral palsy

Inertial devices allow for obtaining a large amount of information related to external load during official competitions. The study aimed to analyse fatigue in different functional classification players of a Football 7-a-side for people with cerebral palsy or acquired brain injury team, considering the movements, speed changes and impacts during the 2020 Spanish National League matches (n = 12). The analyzed independent variables were the different functional classifications (FC) of the players, FC1, FC2 and FC3, and also time. Regarding the dependent variables, kinematic objective external load (displacements and speed changes), and neuromuscular objective external load (impacts) were considered. This study is an empirical investigation that follows an associative and descriptive analysis, ANOVA test, and a Bonferroni post hoc test (multiple comparisons) were carried out between the external load variables based on FC and time. The results show differences between FC1 for people with greater functional limitation to FC3, and athletes with less functional limitation depending on the time of the match. FC2 players presented greater competitive demands in specific moments of the match than FC3 athletes because of the requirements of the competition. Furthermore, evaluating different FC players with inertial devices in official competitions provides useful information regarding the demands of Fa7PC players, which is fundamental for daily training tasks management and injury risk prevention in Fa7PC. The large number of variables associated with inertial devices data collection during training sessions and official competitions in Fa7PC allows us to understand the demands of CP players, as well as how to make decisions during the games and training process, namely for reducing the injury risk.

Análisis de las notificaciones de úlceras cutáneas inducidas por medicamentos en España / Analysis of notifications of drug-induced skin ulcers in Spain

Las úlceras cutáneas son un serio problema de salud, el cual tiene repercusiones socioeconómicas y laborales muy importantes con una elevada tendencia a la cronicidad y recidiva, estimándose que hasta el 50% de ellas permanecerán activas entre 6 meses y un año. Objetivo: Estudio del papel de los medicamentos en la etiología de las úlceras cutáneas. Material y método: Estudio de todas las notificaciones espontáneas relativas a úlceras cutáneas que constan en la base de datos del Sistema Español de Farmacovigilancia de medicamentos de uso humano.Resultados: Se identificaron 292 notificaciones en las que constaban sospechas de reacción adversa a medicamentos (RAM) del tipo lesión ulcerosa relacionadas con el consumo de medicamentos. Estaban implicados 369 medicamentos que suponen 427 principios activos. Las úlceras fundamentalmente aparecían en mujeres con una media de edad de 56,6 años. Los medicamentos sospechosos más frecuentemente notificados fueron los iSGLT-2, vacunas frente al COVID-19, metotrexato, hidroxicarbamida, trimetropim-sulfametoxazol, foscarnet trisódico hexahidrato, ribavirina, docetaxel, acenocumarol e imiquimod y asociación de lidocaína Hcl-pentosano polisulfato sodio-triamcinolona acetónido. Discusión: Numerosos medicamentos tienen como reacción adversa la aparición de úlceras. No debería descartarse esta posibilidad ante la aparición de una lesión cutánea nueva tras la administración de un nuevo medicamento dado que el 25% de las RAM eran desconocidas en el momento de su notificación, como eran los casos de úlceras asociadas a los i-SGLT2 y a las vacunas contra el COVID al inicio de su comercialización; sin embargo, gracias al hecho de seguir notificando las sospechas de RAM, se crearon alertas sanitarias advirtiendo de este hecho y es por ello que aconsejamos seguir notificando cualquier sospecha de RAM a los sistemas regionales de farmacovigilancia.(AU)

Skin ulcers are a serious health problem with significant socioeconomic and labour repercussions and a high tendency to chronicity and recurrence; approximately, up to 50% remain active between six months to one year. Aim: To study the role of drugs in the aetiology of skin ulcers. Material and method: A comprehensive study of all spontaneous reports related to skin ulcers that appear in the Spanish Pharmacovigilance System of Medicines for Human Use database. Results: A total of 292 reports were identified containing suspected adverse drug reactions (ADRs) of ulcer lesion type. Three hundred sixty-nine medications with 427 active ingredients were identified. The ulcers appeared mainly in women with a mean age of 56.6 years. The most frequently reported suspected drugs were SGLT-2, vaccines against COVID-19, methotrexate, hydroxycarbamide, trimethoprim-sulfamethoxazole, foscarnet trisodium hexahydrate, ribavirin, docetaxel, acenocumarol and imiquimod, and the combination of lidocaine Hcl-pentosan polysulfate sodium-triamcinolone acetonide. Discussion: Numerous medications may cause ulcers as an adverse reaction. This possibility should not be ruled out when a new skin lesion appears after the administration of new drugs since 25% of the ADRs were unknown at the time of their notification, as were the cases of ulcers associated with i-SGLT2 and vaccines against COVID at the beginning of their commercialization. However, informative health alerts can be generated by continuously notifying suspected ADRs, so we strongly advise reporting any suspected ADRs to the regional pharmacovigilance system.(AU)

Filtro de vena cava inferior ante diagnóstico de trombosis venosa profunda en gestante en trabajo de parto. A propósito de un caso clínico / Inferior vena cava filter before diagnosis of deep venous thrombosis in a pregnant woman in labor: A case report

Introducción: El embarazo representa un estado procoagulante que aumenta el riesgo de fenómenos trombóticos en la mujer. Al igual que en la población no gestante, deberemos diagnosticar y tratar lo más precozmente posible dichos eventos para evitar la migración del trombo a otras localizaciones. La anticoagulación constituye la medida terapéutica de primera línea. Sin embargo, ciertas situaciones de aumento de sangrado como el trabajo de parto pueden suponer una contraindicación para iniciar dicha anticoagulación. En el siguiente artículo se desarrolla un caso clínico en el que el diagnóstico de trombosis venosa profunda tuvo lugar al inicio del trabajo de parto. Principales síntomas y/o hallazgos clínicos: Aumento de diámetro de miembro inferior izquierdo, con enrojecimiento del mismo y aumento de temperatura local. La paciente describía dolor a nivel de dicha extremidad desde hacía 15 días. No presentaba disnea y la saturación de oxígeno era del 100%. Diagnósticos principales: Trombosis venosa profunda, trabajo de parto. Intervenciones terapéuticas: La contraindicación de anticoagulación y la necesidad de un tratamiento inmediato plantearon el filtro de vena cava inferior como la opción más razonable. Resultados: Tras la colocación del filtro, el parto cursó sin incidencias; no migró el émbolo y el filtro se retiró a los 29 días del parto sin complicaciones. Conclusión: Pese a nuestra escasa experiencia clínica en el manejo de estos casos, podemos afirmar que el filtro de vena cava inferior representa una opción razonable y segura en los casos de trombosis de miembros inferiores en mujeres en trabajo de parto.(AU)

Introduction: Pregnancy represents a procoagulant state that increases women's risk of thrombotic phenomena. As in the non-pregnant population, we must diagnose and treat these events as early as possible to avoid the migration of the thrombus to other locations. Anticoagulation is the first-line therapeutic measure. However, certain situations of increased bleeding such as labor may be a contraindication to initiate such anticoagulation. The following article develops a clinical case in which the deep vein thrombosis diagnosis occurred at the onset of labor. Main symptoms and/or clinical findings: Increase in diameter of the left lower limb, with redness of the same and increase in local temperature. The patient described pain at the level of this limb for 15 days. He had no dyspnea and oxygen saturation was 100%. Main diagnoses: Deep vein thrombosis, labor. Therapeutic interventions: The contraindication of anticoagulation and the need for immediate treatment raised the inferior vena cava filter as the most reasonable option. Results: After the placement of the filter, the delivery proceeded without incident. The plunger did not migrate and the filter was removed 29 days after delivery without complications. Conclusion: Despite our limited clinical experience in the management of these cases, we can affirm that the inferior vena cava filter represents a reasonable and safe option in cases of thrombosis of the lower limbs in women in labor.(AU)

Spinal gunshot wounds: A retrospective, multicenter, cohort study. / [Artículo traducido] Lesiones vertebrales por proyectil de arma de fuego: estudio de cohorte retrospectivo, multicéntrico.

INTRODUCTION AND OBJECTIVE: To describe the demographic and clinical characteristics and treatment of patients with spinal gunshot wounds across Latin America. MATERIAL AND METHODS: Retrospective, multicenter cohort study of patients treated for gunshot wounds to the spine spanning 12 institutions across Latin America between January 2015 and January 2022. Demographic and clinical data were recorded, including the time of injury, initial assessment, characteristics of the vertebral gunshot injury, and treatment. RESULTS: Data on 423 patients with spinal gunshot injuries were extracted from institutions in Mexico (82%), Argentina, Brazil, Colombia, and Venezuela. Patients were predominantly male civilians in low-risk-of-violence professions, and of lower/middle social status, and a sizeable majority of gunshots were from low-energy firearms. Vertebral injuries mainly affected the thoracic and lumbar spine. Neurological injury was documented in 320 (76%) patients, with spinal cord injuries in 269 (63%). Treatment was largely conservative, with just 90 (21%) patients treated surgically, principally using posterior open midline approach to the spine (79; 87%). Injury features distinguishing surgical from non-surgical cases were neurological compromise (P = 0.004), canal compromise (P < 0.001), dirty wounds (P < 0.001), bullet or bone fragment remains in the spinal canal (P < 0.001) and injury pattern (P < 0.001). After a multivariate analysis through a binary logistic regression model, the aforementioned variables remained statistically significant except neurological compromise. CONCLUSIONS: In this multicenter study of spinal gunshot victims, most were treated non-surgically, despite neurological injury in 76% and spinal injury in 63% of patients.

Changes in benign prostatic hyperplasia management in Valencia: a real-world evidence analysis.

INTRODUCTION AND OBJECTIVES: A training program was developed to increase general practitioners' engagement in the optimal management of Benign Prostatic Hyperplasia (BPH). The goal of this study was to evaluate changes in BPH management after the implementation of a training program. MATERIAL AND METHODS: This observational retrospective cohort study was conducted between 2019 and 2020. Aggregated data were analyzed in three evaluation periods (2010, 2012 and 2015), addressing quality indicators for diagnosis, treatment, and treatment outcomes. RESULTS: Overall, 118 795 patients who presented any data points were included. All quality indicators (number of IPSS and PSA determinations) increased between the first period and the last. Combination (α-blocker + 5-ARI) therapy was increasingly prescribed during the study periods whereas the proportion of prescriptions for single-agent α-blocker showed no significant differences among the periods analyzed. However, the total number of patients eligible for combination therapy who actually received this treatment was low in all periods (7.5%, 17.9%, and 20.1%, in 2010, 2012, and 2015, respectively). The outcome indicators revealed a decrease in referrals to the urology unit mostly among newly diagnosed patients. Even though the proportion of patients who underwent BPH-related surgeries increased significantly from the first to the second period, the number of surgeries remained stable between the second and third periods. CONCLUSIONS: The training program had a generally positive impact on the management of BPH patients in PC, but the overall study period may be insufficient to show an effect on some outcome indicators such as the number of surgeries.

A cathodoluminescence study of InP/InGaP axially heterostructured NWs for tandem solar cells.

Axially heterostructured nanowires (NWs) constitute a promising platform for advanced electronic and optoelectronic nanodevices. The presence of different materials in these NWs introduces a mismatch resulting in complex strain distributions susceptible of changing the band gap and carrier mobility. The growth of these NWs presents challenges related to the reservoir effect in the catalysts droplet that affect to the junction abruptness, and the occurrence of undesired lateral growth creating core-shell heterostructures that introduce additional strain. We present herein a cathodoluminescence (CL) analysis on axially heterostructured InP/InGaP NWs with tandem solar cell structure. The CL is complemented with micro Raman, micro photoluminescence (PL), and high resolution transmission electron microscopy measurements. The results reveal the zinc blende structure of the NWs, the presence of a thin InGaP shell around the InP bottom cell, along with its associated strain, and the doping distribution.

Is low back pain a risk/prognostic factor for the development and/or progression of temporomandibular disorders? A systematic review with meta-analysis.

OBJECTIVES: To evaluate the association between low back pain (LBP) and painful temporomandibular disorders (TMDs). METHODS: Systematic review of observational studies. Searches were conducted using OVID MEDLINE, CINHAL, Web of Science and PUBMED databases up to 21 October 2022. Qualitative and quantitative analyses were performed. Risk of bias (RoB) was assessed using the Quality in Prognosis Studies tool (QUIPS). RESULTS: Eight studies were included in the present review with meta-analysis. The first onset of TMDs was more likely in patients with previous chronic LBP (hazard ratio (HR) 1.53 [95% confidence interval (CI): 1.28; 1.83, p < .00001]). In addition, patients with chronic LBP had 3.25 times the odds (OR) [95% CI: 1.94; 5.43, p < .00001] of having chronic TMDs than those who did not have chronic LBP. In addition, the higher the exposure to chronic LBP, the higher the risk of developing a first onset of TMDs. CONCLUSIONS: Chronic LBP can be considered a risk/contributing factor for painful TMDs. Although there is a high certainty in the evidence linking chronic LBP with the risk of a first onset of TMDs, there are insufficient studies to draw definitive conclusions. Furthermore, while an association between chronic LBP and chronic TMDs and a dose-effect was observed between these two conditions, a limited number of studies and evidence exist to support these findings. Future studies are needed to increase the body of evidence.

A deep learning model for Alzheimer's disease diagnosis based on patient clinical records.

BACKGROUND: Dementia, with Alzheimer's disease (AD) being the most common type of this neurodegenerative disease, is an under-diagnosed health problem in older people. The creation of classification models based on AD risk factors using Deep Learning is a promising tool to minimize the impact of under-diagnosis. OBJECTIVE: To develop a Deep Learning model that uses clinical data from patients with dementia to classify whether they have AD. METHODS: A Deep Learning model to identify AD in clinical records is proposed. In addition, several rebalancing methods have been used to preprocess the dataset and several studies have been carried out to tune up the model. RESULTS: Model has been tested against other well-established machine learning techniques, having better results than these in terms of AUC with alpha less than 0.05. CONCLUSIONS: The developed Neural Network Model has a good performance and can be an accurate assisting tool for AD diagnosis.

Descripción y análisis de mortalidad a corto y medio plazo en una unidad de cuidados respiratorios intermedios: nuestra experiencia / Pdescription and analysis of short and medium-term mortality in an intermediate respiratory care unit: our experience

Objetivo: Describir y analizar la mortalidad de los pacientes que ingresan en nuestra UCRI, tanto durante el ingreso en dicha UCRI, como a lo largo de toda la estancia hospitalaria, y a los 3 y 6 meses del alta hospitalaria. Metodología: Estudio prospectivo de 380 pacientes, no Covid, ingresados en nuestra UCRI, destinada al tratamiento del fallo respiratorio agudo con VMNI, a lo largo de año y medio de actividad. Se recogieron datos demográficos, índice de Charlson modificado (m), tipo de fallo respiratorio, servicio de pertenencia, días de estancia en UCRI y la mortalidad tanto en UCRI como hospitalaria, y a los 3 y 6 meses del alta del hospital. Resultados: El 55% eran varones con una edad media de 71 años y un índice de Charlson (m) de 6,4. La mortalidad en UCRI fue del 16.4% y la intrahospitalaria del 27%, relacionándose ambas con la edad, el índice de Chalson (m), el servicio de pertenencia y el fallo respiratorio hipoxémico. Tras el alta hospitalaria, la supervivencia a los tres meses fue del 83,6% y a los 6 meses del 75,5% relacionándose ambas con la edad y el índice de Charlson (m). Conclusiones: Las UCRIs son útiles en el tratamiento del fallo respiratorio agudo en pacientes con alta carga de comorbilidad, permitiendo a tales pacientes tener una elevada supervivencia a medio plazo tras el alta hospitalaria. (AU)

Objective: describe and analyze the mortality of patients admitted to our IRCU, both during admission to said IRCU, and throughout the entire hospital stay, and 3 and 6 months after hospital discharge. Methodology: prospective study of 380 non-Covid patients admitted to our IRCU, intended for the treatment of acute respiratory failure with NIV, over a year and a half of activity. Demographic data, modified Charlson index (m), type of respiratory failure, service affiliation, days of stay in the IRCU, and mortality both in the IRCU and in hospital, and at 3 and 6 months after hospital discharge were collected. Results: 55% were men with a mean age of 71 years and a Charlson index (m) of 6.4. Mortality in the IRCU was 16.4% and in-hospital mortality was 27%, both being related to age, the Chalson index (m), the service to which they belong, and hypoxemic respiratory failure. After hospital discharge, survival at three months was 83.6% and at 6 months was 75.5%, both related to age and the Charlson index (m). Conclusions: IRCU are useful in the treatment of acute respiratory failure in patients with a high burden of comorbidity, allowing such patients to have a high medium-term survival after hospital discharge.

Soporte telemático de autogestión para pacientes con apnea obstructiva del sueño en tratamiento con CPAP: aspectos metodológicos y resultados preliminares del ensayo clinico telesas / Telematic self-management support for patients with obstructive sleep apnea under CPAP treatment: methodological aspects and preliminary results of the telesas clinical trial

Objetivo: Comprobar si un programa de telemedicina mejora el cumplimiento con CPAP, alcanzando un uso de, al menos, 4 horas al día en el 90% de los pacientes. Realizamos un estudio piloto para comprobar la viabilidad de un proyecto multicéntrico en el que perfeccionaremos dicho programa. Metodología: Pacientes con AOS severa poco sintomáticos en tratamiento con CPAP fueron randomizados a seguimiento habitual o seguimiento habitual más un programa de telemedicina durante 6 meses. Dentro de este programa, las variables de telemonitorización, la aparición de efectos secundarios y la presencia de sueño reparador eran analizadas para generar alarmas e instrucciones al paciente para la autogestión precoz de los problemas presentados con la CPAP. Resultados: 60 pacientes fueron randomizados, 33 al grupo intervención y 27 al grupo control, sin diferencias significativas en las variables basales. El 80% eran hombres con un rango de edad entre los 24 y 75 años. Solo hubo un abandono en el grupo control. Conclusiones: El uso de nuestro programa de telemedicina no ha supuesto ningún problema para los pacientes incluidos a pesar de la horquilla amplia de edad, siendo viable el desarrollo de un estudio a mayor escala con una herramienta de telemedicina perfeccionada.

Basis: poor compliance with CPAP is a problem at a clinical and research level, assuming the expected results are not achieved. The benefits of using telemedicine in obstructive sleep apnea (OSA) are inconclusive, with its positive effect on compliance being the most consistent in the literature. Objective: to check if a telemedicine program improves compliance with CPAP, reaching use of at least 4 hours a day in 90% of patients. We carried out a pilot study to verify the viability of a multicenter project in which we will perfect this program. Method: patients with severe OSA with few symptoms on CPAP treatment were randomized to usual follow-up or usual follow-up plus a telemedicine program for 6 months. Within this program, the telemonitoring variables, the appearance of side effects and the presence of restorative sleep were analyzed to generate alarms and instructions to the patient for early self-management of the problems presented with CPAP. Preliminary results: 60 patients were randomized, 33 to the intervention group and 27 to the control group, with no significant differences in the baseline variables. 80% were men with an age range between 24 and 75 years. There was only one dropout in the control group. Conclusions: the use of our telemedicine program has not posed any problems for the included patients despite the wide age range, making it feasible to develop a larger-scale study with an improved telemedicine tool.
