RESUMEN
INTRODUCTION: In patients with obstructive sleep apnea (OSA), novel metrics such as hypoxic burden (HB) and sleep apnea-specific pulse-rate response (ΔHR) may better correlate with cardiovascular diseases (CVD) than the apnea-hypopnea index (AHI). This manuscript aims to assess the correlation between ΔHR and HB with subclinical atherosclerosis in patients with OSA, testing the hypothesis that elevated ΔHR and HB are associated with subclinical atherosclerosis development. METHODS: In a prospective study, individuals aged 20-65 years with suspected OSA without known comorbidities were consecutively recruited and defined as OSA (AHI≥5events/h) or healthy controls. Using bilateral carotid ultrasonography, common carotid intima-media thickness (CIMT) was assessed and the identification of at least one atheromatous plaque defined the presence of subclinical atherosclerosis. ΔHR, and HB were derived from pulse-oximetry. RESULTS: We studied 296 patients of age 45±10 years old, of whom 28% were women, and with a BMI of 30.3±5.3kg/m2. Overall, 245 had OSA and 51 were healthy controls. After controlling for confounding variables higher ΔHR but not HB, was associated with higher CIMT (p=0.006) and higher time spent with oxygen saturation below 90% (T90) was associated with an increase in carotid atheroma plaques (p=0.032). When stratifying OSA based on HB tertiles, we observed that within tertile 2 of HB, an increase in ΔHR was associated with larger CIMT (p=0.017). CONCLUSION: A higher ΔHR is associated with an increase in CIMT among adult patients with OSA. This study suggests that ΔHR could be a biomarker of risk for CVD in patients with OSA.

Long-COVID (LC) is characterised by persistent symptoms for at least 3 months after acute infection. A dysregulation of the immune system and a persistent hyperinflammatory state may cause LC. LC patients present differences in activation and exhaustion states of innate and adaptive compartments. Different T CD4+ cell subsets can be identified by differential expression of chemokine receptors (CCR). However, changes in T cells with expression of CCRs such as CCR6 and CXCR3 and their relationship with CD8+ T cells remains unexplored in LC. Here, we performed unsupervised analysis and found CCR6+ CD4+ subpopulations enriched in COVID-19 convalescent individuals upon activation with SARS-CoV-2 peptides. SARS-CoV-2 specific CCR6+ CD4+ are decreased in LC patients, whereas CXCR3+ CCR6- and CCR4+ CCR6- CD4+ T cells are increased. LC patients showed lower IFN-γ-secreting CD8+ T cells after stimulation with SARS-CoV-2 Spike protein. This work underscores the role of CCR6 in the pathophysiology of LC.

INTRODUCTION: Treatment with LABA/LAMA is recommended in GOLD B patients. We hypothesized that triple therapy (LABA/LAMA/ICS) will be superior to LABA/LAMA in achieving and maintaining clinical control (CC), a composite outcome that considers both impact and disease stability in a subgroup of GOLD B patients (here termed GOLD B+ patients) characterized by: (1) remaining symptomatic (CAT≥10) despite regular LABA/LAMA therapy; (2) having suffered one moderate exacerbation in the previous year; and (3) having blood eosinophil counts (BEC) ≥150cells/µL. METHODS: The ANTES B+ study is a prospective, multicenter, open label, randomized, pragmatic, controlled trial designed to test this hypothesis. It will randomize 1028 B+ patients to continue with their usual LABA/LAMA combination prescribed by their attending physician or to begin fluticasone furoate (FF) 92µg/umeclidinium (UMEC) 55µg/vilanterol (VI) 22µg in a single inhaler q.d. for 12 months. The primary efficacy outcome will be the level of CC achieved. Secondary outcomes include the clinical important deterioration index (CID), annual rate of exacerbations, and FEV1. Exploratory objectives include the interaction of BEC and smoking status, all-cause mortality and proportion of patients on LABA/LAMA arm that switch therapy arms. Safety analysis include adverse events and incidence of pneumonia. RESULTS: The first patient was recruited on February 29, 2024; results are expected in the first quarter of 2026. CONCLUSIONS: The ANTES B+ study is the first to: (1) explore the efficacy and safety of triple therapy in a population of B+ COPD patients and (2) use a composite index (CC) as the primary result of a COPD trial.

Introduction: Lymphangioleiomyomatosis (LAM) is a rare disease that affects women almost exclusively. We aimed to determine the psychological profile in patients with LAM, and their potential association with sociodemographic and clinical features, and to know their role in coping with the disease. Material and methods: Cross-sectional and descriptive study in collaboration with the Spanish Association of LAM (AELAM). The variables measured were: socio-demographic, psychological (anxiety, depression, demoralization, spirituality, resilience, social support), clinical (treatment) and health-related quality of life. Results: We studied 87 LAM patients, with a mean (SD) age of 47.7 (7.7) years, and time since diagnose was 10.1 (5.4) years. 75.9% of patients were receiving sirolimus or everolimus, and oxygen therapy was required in 34.5% of patients. Anxiety was found in 46% of patients, depression in 55%, while only 2% presented demoralization and 14% deficit in spirituality. Social support and resilience were adequate. The "non-severe" group (without oxygen therapy) presented worse results in anxiety. A structural equation model to explore association between variables, showed very adequate fit indices: χ2(14) = 29.743 (p = .074); CFI = .983; TLI = .967; SRMR = .058; RMSEA = .075[.000-.128]. The model identifies resilience, spirituality and social support as "protective factors" from anxiety, depression, and demoralization. Conclusions: This study performed on a large series of women with LAM describes their psychological profile, in addition to showing how they cope with the disease. We have found that other psychological constructs, such as perceived social support and resilience, are protective factors. Early psychological evaluation and intervention is necessary to reduce comorbidities and prevent mental health problems in women with LAM.
Introducción: La linfangioleiomiomatosis (LAM) es una enfermedad rara que afecta casi exclusivamente a las mujeres. Nuestro objetivo fue determinar el perfil psicológico en los pacientes con LAM, y su potencial asociación con características sociodemográficas y clínicas, y conocer su papel en el afrontamiento de la enfermedad. Material y métodos: Estudio transversal y descriptivo en colaboración con la Asociación Española de LAM (AELAM). Las variables medidas fueron: sociodemográficas, psicológicas (ansiedad, depresión, desmoralización, espiritualidad, resiliencia, apoyo social), clínicas (tratamiento) y calidad de vida relacionada con la salud. Resultados: Se estudiaron 87 pacientes con LAM, con una edad media (DE) de 47,7 ± 7,7 años y un tiempo desde el diagnóstico de 10,1 ± 5,4 años. El 75,9% de los pacientes estaban recibiendo sirolimus o everolimus, y el 34,5% de los pacientes requirió oxigenoterapia. La ansiedad se encontró en el 46% de los pacientes, la depresión en el 55%, mientras que solo el 2% presentó desmoralización y el 14% déficit en la espiritualidad. El apoyo social y la resiliencia fueron adecuados. El grupo «no grave¼ (sin oxigenoterapia) presentó peores resultados en ansiedad. Un modelo de ecuaciones estructurales para explorar asociación entre variables, mostró índices de ajuste muy adecuados: χ2(14) = 29,743 (p = 0,074); CFI = 0,983; TLI = 0,967; SRMR = 0,058; RMSEA = 0,075 (0,000-0,128). El modelo identifica la resiliencia, la espiritualidad y el apoyo social como «factores protectores¼ contra la ansiedad, la depresión y la desmoralización. Conclusiones: Este estudio realizado en una amplia serie de mujeres con LAM describe su perfil psicológico, además de mostrar cómo afrontan la enfermedad. Hemos descubierto que otros constructos psicológicos, como el apoyo social percibido y la resiliencia, son factores protectores. La evaluación e intervención psicológica temprana es necesaria para reducir las comorbilidades y prevenir problemas de salud mental en mujeres con LAM.
RESUMEN
BACKGROUND AND OBJECTIVES: The COVID-19 pandemic had a significant impact in population health worldwide, and particularly in people with pre-existing chronic diseases. Early risk identification and stratification is essential to reduce the impact of future outbreaks of pandemic potential. This study aimed to comprehensively examine factors associated with COVID-19 mortality across the pandemic waves in Spain. METHODS: A retrospective study analyzed the characteristics of 13,974 patients admitted to Spanish hospitals due to SARS-CoV-2 infection from 2020-01-28 to 2022-12-31. The demographic and clinical features of patients during hospitalization on each pandemic waves were analyzed. MAIN FINDINGS: The findings highlight the heterogeneity of patient characteristics, comorbidities and outcomes, across the waves. The high prevalence of cardiometabolic diseases (53.9%) among COVID-19 patients emphasizes the importance of controlling these risk factors to prevent severe COVID-19 outcomes. CONCLUSIONS: In summary, the study associate hospital mortality with factors such as advanced age and comorbidities. The decline in mortality after the 4th wave indicates potential influences like vaccination, viral adaptation, or improved treatments. Notably, dementia and cancer metastases emerge as critical factors linked to higher mortality, highlighting the importance of addressing these conditions in COVID-19 management and preparing for future challenges.

Introduction: The patient experience is defined as all the interactions that occur between patients and the healthcare system. The experience of patients with respiratory disease with home respiratory treatments (HRT) is not captured in currently available Patient-Reported Outcome Measures (PROM). We present the psychometric validation of the Patient-Reported Experience Measure (PREM) 'HowRwe' in Spanish and for respiratory patients with HRT. Methods: After translation following ISPOR guidelines (International Society for Pharmacoeconomics and Outcomes Research), the questionnaire was administered to adult respiratory patients who were receiving treatment at Hospital Universitario de La Princesa. The administration was done in two stages with 6 months of difference between the pre- and post-test. Results: We studied 228 respiratory patients, with a mean (SD) age of 64.1 (13.2) years, 52.2% were men, 68.0% were married or coupled, and 56.6% were retired. Reliability coefficients of the scale were adequate, with α = .921 and Ω = .929 for pre-test, and α = .940 and Ω = .958 for post. The confirmatory factor analysis tested for pre- and post-intervention, showed an excellent overall fit: χ2(2) = 49.380 (p < .001), CFI = .941 and SRMR = .072; and χ2(2) = 37.579 (p < .001), CFI = .982 and SRMR = .046, respectively. No statistically significant associations were observed for neither age, adherence nor quality of life, except between HowRwe post-test and quality of life pre-test (r = .14 [.01,.26]; p = .035). No significant differences were found in sociodemographic variables. No differences in pre-test or post-test were found in effect of HRT. 85.6% of patients found the content of HowRwe "Useful", and the preferred channel to respond it were paper, app and email. Conclusions: The Spanish version of the 'HowRwe' questionnaire to measure the experience in respiratory patients with home respiratory treatments (HRT), has adequate psychometric properties and conceptual and semantic equivalence with the original English version.
Introducción: La experiencia del paciente se define como todas las interacciones que ocurren entre los pacientes y el sistema de salud. La experiencia de los pacientes con enfermedades respiratorias con terapias respiratorias domiciliarios (TRD) no se refleja en las Medidas de resultados informados por el paciente (PROM) disponibles actualmente. Presentamos la validación psicométrica de la Medida de Experiencia Reportada por el Paciente (PREM por sus siglas en inglés) 'HowRwe' en español y para pacientes respiratorios con TRD. Métodos: Después de la traducción siguiendo las pautas de ISPOR (Sociedad Internacional de Farmacoeconomía e Investigación de Resultados), el cuestionario se administró a pacientes respiratorios adultos que estaban recibiendo tratamiento en el Hospital Universitario de La Princesa. La administración se realizó en dos etapas con 6 meses de diferencia entre el pre y post test. Resultados: Se estudiaron 228 pacientes respiratorios, con una edad media (DE) de 64,1 ± 13,2 años, el 52,2% eran hombres, el 68,0% estaban casados o en pareja y el 56,6% eran jubilados. Los coeficientes de confiabilidad de la escala fueron adecuados, con α = .921 y Ω = .929 para el pretest, y α = .940 y Ω = .958 para el post. El análisis factorial confirmatorio testado para pre y postintervención, mostró un ajuste global excelente: χ2(2) = 49.380 (p < .001), CFI = .941 y SRMR = .072; y χ2(2) = 37,579 (p < .001), CFI = .982 y SRMR = .046, respectivamente. No se observaron asociaciones estadísticamente significativas ni para la edad, la adherencia ni para la calidad de vida, excepto entre HowRwe postest y calidad de vida pretest (r = .14 [.01,.26];p = .035). No se encontraron diferencias significativas en las variables sociodemográficas. No se encontraron diferencias en el efecto de la TRH en el pretest o postest. El 85,6% de los pacientes encontró "útil" el contenido de HowRwe y el canal preferido para responder fue el papel, la aplicación y el correo electrónico. Conclusiones: La versión española del cuestionario 'HowRwe' para medir la experiencia en pacientes respiratorios con tratamientos respiratorios domiciliarios (TRH), tiene adecuadas propiedades psicométricas y equivalencia conceptual y semántica con la versión original en inglés.
RESUMEN
Increased recruitment of transitional and non-classical monocytes in the lung during SARS-CoV-2 infection is associated with COVID-19 severity. However, whether specific innate sensors mediate the activation or differentiation of monocytes in response to different SARS-CoV-2 proteins remain poorly characterized. Here, we show that SARS-CoV-2 Spike 1 but not nucleoprotein induce differentiation of monocytes into transitional or non-classical subsets from both peripheral blood and COVID-19 bronchoalveolar lavage samples in a NFκB-dependent manner, but this process does not require inflammasome activation. However, NLRP3 and NLRC4 differentially regulated CD86 expression in monocytes in response to Spike 1 and Nucleoprotein, respectively. Moreover, monocytes exposed to Spike 1 induce significantly higher proportions of Th1 and Th17 CD4 + T cells. In contrast, monocytes exposed to Nucleoprotein reduce the degranulation of CD8 + T cells from severe COVID-19 patients. Our study provides insights in the differential impact of innate sensors in regulating monocytes in response to different SARS-CoV-2 proteins, which might be useful to better understand COVID-19 immunopathology and identify therapeutic targets.

B and T cell responses were evaluated in patients with rheumatoid arthritis (RA) or psoriatic arthritis (PsA) after 1 or 2 weeks of methotrexate (MTX) withdrawal following each COVID-19 vaccine dose and compared with those who maintained MTX. Adult RA and PsA patients treated with MTX were recruited and randomly assigned to 3 groups: MTX-maintenance (n = 72), MTX-withdrawal for 1 week (n = 71) or MTX-withdrawal for 2 weeks (n = 73). Specific antibodies to several SARS-CoV-2 antigens and interferon (IFN)-γ and interleukin (IL)-21 responses were assessed. MTX withdrawal in patients without previous COVID-19 was associated with higher levels of anti-RBD IgG and neutralising antibodies, especially in the 2-week withdrawal group and with higher IFN-γ secretion upon stimulation with pools of SARS-CoV-2 S peptides. No increment of RA/PsA relapses was detected across groups. Our data indicate that two-week MTX interruption following COVID-19 vaccination in patients with RA or PsA improves humoral and cellular immune responses.
RESUMEN
Introduction: The aim of this study was to analyze the impact of occupational exposure on chronic obstructive pulmonary disease (COPD) and respiratory symptoms in the general Spanish population.MethodsThis was a study nested in the Spanish EPISCAN II cross-sectional epidemiological study that included participants who had completed a structured questionnaire on their occupational history, a questionnaire on respiratory symptoms, and forced spirometry. The data were analyzed using Chi-square and Student's t tests and adjusted models of multiple linear regression and logistic regression.ResultsWe studied 7502 subjects, 51.1% women, with a mean age of 60±11 years. Overall, 53.2% reported some respiratory symptoms, 7.9% had respiratory symptoms during their work activity, 54.2% were or had been smokers, and 11.3% (851 subjects) met COPD criteria on spirometry. A total of 3056 subjects (40.7%) reported exposure to vapors, gases, dust or fumes (VGDF); occupational exposure to VGDF was independently associated with the presence of COPD (OR 1.22, 95% CI: 1.031.44), respiratory symptoms (OR 1.45, 95%: CI 1.301.61), and respiratory symptoms at work (OR 4.69, 95% CI: 3.825.77), with a population attributable fraction for COPD of 8.2%.ConclusionsOccupational exposure is associated with a higher risk of COPD and respiratory symptoms in the Spanish population. These results highlight the need to follow strict prevention measures to protect the respiratory health of workers. (AU)

Introduction: There is still uncertainty about which aspects of cigarette smoking influence the risk of Chronic Obstructive Pulmonary Disease (COPD). The aim of this study was to estimate the COPD risk as related to duration of use, intensity of use, lifetime tobacco consumption, age of smoking initiation and years of abstinence. Methods: We conducted an analytical cross-sectional study based on data from the EPISCAN-II study (n=9092). All participants underwent a face-to-face interview and post-bronchodilator spirometry was performed. COPD was defined as post-bronchodilator FEV1/FVC<70%. Parametric and nonparametric logistic regression models with generalized additive models were used. Results: 8819 persons were included; 858 with COPD and 7961 without COPD. The COPD risk increased with smoking duration up to ≥50 years [OR 3.5 (95% CI: 2.35.4)], with smoking intensity up to ≥39cig/day [OR 10.1 (95% CI: 5.318.4)] and with lifetime tobacco consumption up to >29 pack-years [OR 3.8 (95% CI: 3.14.8)]. The COPD risk for those who started smoking at 22 or later was 0.9 (95% CI: 0.61.4). The risk of COPD decreased with increasing years of cessation. In comparison with both never smokers and current smokers, the lowest risk of COPD was found after 1525 years of abstinence. Conclusion: COPD risk increases with duration, intensity, and lifetime tobacco consumption and decreases importantly with years of abstinence. Age at smoking initiation shows no effect. After 1525 years of cessation, COPD risk could be equal to that of a never smoker. This work suggests that the time it takes to develop COPD in a smoker is about 30 years. (AU)

Introduction We previously reported an increase in respiratory mortality in 2020 in Spain after COVID-19. It is unclear if this rise is sustained in the longer-term. We aimed to determine whether respiratory mortality in 2021 in Spain returned to pre-pandemic levels. Material and methods In an observational, large study using official National Institute of Statistics data, we explored deaths due to respiratory diseases, that is, all causes of death by the standard WHO list of diseases of the respiratory system plus COVID-19, tuberculosis and lung cancer. Using the latest available official data of Spain, we analyzed changes in the mortality pattern in Spain from January 2019 to December 2021. We endorsed STROBE guidance for observational research. Results There were 98,714 deaths due to respiratory diseases in 2021 in Spain, corresponding to 21.9% of all deaths, becoming second in the ranking of causes of death. Respiratory diseases mortality in Spain has not returned to pre-pandemic levels in 2021, still with an increase of 30.3% (95% CI 30.230.4) compared to rates in 2019. All respiratory-specific causes of death decreased in 2021, except for lung cancer, that increased in women and decreased in men compared to 2019 (both p<0.05). In a multivariate analysis some established risk factors for respiratory diseases mortality were confirmed, such as male gender and older age; further, an association with reduced mortality in rural Spain was observed, still with a large geographical variability. Conclusions The COVID-19 pandemic has had a lasting impact on deaths due to respiratory diseases and certain specific causes of death in 2021, and it has disproportionately affected certain regions (AU)
Introducción Previamente informamos de un aumento de la mortalidad respiratoria en 2020 en España tras la COVID-19. No está claro si este aumento se mantiene a largo plazo. Nuestro objetivo fue determinar si la mortalidad respiratoria en 2021 en España volvió a los niveles previos a la pandemia. Métodos En un gran estudio observacional con datos oficiales del Instituto Nacional de Estadística exploramos las muertes por enfermedades respiratorias, es decir, todas las causas de muerte según la lista estándar de enfermedades del sistema respiratorio de la Organización Mundial de la Salud más COVID-19, tuberculosis y cáncer de pulmón. Utilizando los últimos datos oficiales disponibles de España analizamos los cambios en el patrón de mortalidad en España desde enero de 2019 hasta diciembre de 2021. Seguimos la guía STROBE para investigación observacional. Resultados Se produjeron 98.714 muertes por enfermedades respiratorias en 2021 en España, lo que corresponde a 21,9% del total de muertes, situándose en el segundo lugar del ranking de causas de muerte. La mortalidad por enfermedades respiratorias en España no ha vuelto a los niveles previos a la pandemia en 2021, aun con un aumento de 30,3% (IC 95% 30,2-30,4) respecto a las tasas de 2019. Todas las causas de muerte específicas de las vías respiratorias disminuyeron en 2021, excepto el cáncer de pulmón, que aumentó en mujeres y disminuyó en hombres en comparación con 2019 (ambos p < 0,05). En un análisis multivariado se confirmaron algunos factores de riesgo establecidos para la mortalidad por enfermedades respiratorias, como el género masculino y la edad avanzada; además, se observó una asociación con la reducción de la mortalidad en la España rural, aun con una gran variabilidad geográfica. Conclusiones La pandemia de COVID-19 ha tenido un impacto duradero en las muertes por enfermedades respiratorias y ciertas causas específicas de muerte en 2021, y ha afectado de manera desproporcionada a ciertas regiones (AU)

The COPD risk for those who started smoking at 22 or later was 0.9 (95% CI: 0.6-1.4). The risk of COPD decreased with increasing years of cessation. In comparison with both never smokers and current smokers, the lowest risk of COPD was found after 15-25 years of abstinence. CONCLUSION: COPD risk increases with duration, intensity, and lifetime tobacco consumption and decreases importantly with years of abstinence. Age at smoking initiation shows no effect. After 15-25 years of cessation, COPD risk could be equal to that of a never smoker. This work suggests that the time it takes to develop COPD in a smoker is about 30 years.

BACKGROUND: An association of ABO blood group and COVID-19 remains controversial. METHODS: Following STROBE guidance for observational research, we explored the distribution of ABO blood group in patients hospitalized for acute COVID-19 and in those with Long COVID. Contingency tables were made and risk factors were explored using crude and adjusted Mantle-Haentzel odds ratios (OR and 95% CI). RESULTS: Up to September 2022, there were a total of 5,832 acute COVID-19 hospitalizations in our hospital, corresponding to 5,503 individual patients, of whom blood group determination was available for 1,513 (27.5%). Their distribution by ABO was: 653 (43.2%) group 0, 690 (45.6%) A, 113 (7.5%) B, and 57 (3.8%) AB, which corresponds to the expected frequencies in the general population. In parallel, of 676 patients with Long COVID, blood group determination was available for 135 (20.0%). Their distribution was: 60 (44.4%) from group 0, 61 (45.2%) A, 9 (6.7%) B, and 5 (3.7%) AB. The distribution of the ABO system of Long COVID patients did not show significant differences with respect to that of the total group (p ≥ 0.843). In a multivariate analysis adjusting for age, sex, ethnicity, and severity of acute COVID-19 infection, subgroups A, AB, and B were not significantly associated with developing Long COVID with an OR of 1.015 [0.669-1.541], 1.327 [0.490-3.594] and 0.965 [0.453-2.058], respectively. The effect of the Rh+ factor was also not significant 1,423 [0.772-2,622] regarding Long COVID. CONCLUSIONS: No association of any ABO blood subgroup with COVID-19 or developing Long COVID was identified.
