Occult cancer in patients with unprovoked venous thromboembolism: A nested case-control study.

OBJECTIVES: Detecting occult cancer in patients with unprovoked venous thromboembolism (VTE) remains a significant challenge. Our objective was to investigate the potential predictive role of coagulation-related biomarkers in the diagnosis of occult malignancies. METHODS: We conducted a nested case-control study with a 1-year prospective cohort of 214 patients with unprovoked VTE, with a focus on identifying occult cancer. At the time of VTE diagnosis, we measured various biomarkers, including soluble P-selectin (sP-selectin), dimerized plasmin fragment D (D-dimer), platelets, leukocytes, hemoglobin, total extracellular vesicles (EVs), EVs expressing tissue factor on their surface (TF+EVs), and EVs expressing P-selectin on their surface (Psel+EVs) in all participants. RESULTS: We observed statistically significant increased levels of sP-selectin (P = .015) in patients with occult cancer. Despite an increase in Psel+EVs, TF+EVs, D-dimer, and platelets within this group, however, no significant differences were found. When sP-selectin exceeded 62 ng/mL and D-dimer surpassed 10,000 µg/L, the diagnosis of occult cancer demonstrated a specificity of up to 91% (95% CI, 79.9%-96.7%). CONCLUSIONS: The combination of sP-selectin and D-dimer can be a valuable biomarker in detecting occult cancer in patients with unprovoked VTE. Further research is necessary to ascertain whether easily measurable biomarkers such as sP-selectin and D-dimer can effectively distinguish between patients who have VTE with and without hidden malignancies.

Evaluation of Different Doses in Inhaled Therapy: A Comprehensive Analysis.

BACKGROUND: Currently, there is a considerable degree of confusion over the dosage of inhaled medications. Here, we carried out a review of all the doses used for the devices used in inhalation therapy. METHODS: We first performed a systematic search of the different inhalation devices included on the July 2023 Spanish Ministry of Health Billing List. We then consulted the Spanish Agency for Medicines and Health Products to find the updated official label and to obtain the information on the exact composition. RESULTS: We identified 90 unique products, of which 22 were long-acting bronchodilators (and combinations thereof) and 68 were products containing inhaled corticosteroids (ICS). Overall, 10 products with bronchodilators and 40 with ICS were marketed with the metered dose, while 11 with bronchodilators and 28 with ICS were marketed with the delivered dose. In addition, in some bronchodilators, the drug was referred to as a type of salt, whereas in others the information referred to the drug itself. CONCLUSIONS: Our data show that for each inhaled drug there may be up to four different doses and that the marketed name may refer to any of these. Clinicians must be aware of these different dosages when prescribing inhaled medications.

Diagnostic delay of associated interstitial lung disease increases mortality in rheumatoid arthritis.

Rheumatoid arthritis (RA) is a systemic autoimmune disease whose main extra-articular organ affected is the lung, sometimes in the form of diffuse interstitial lung disease (ILD) and conditions the prognosis. A multicenter, observational, descriptive and cross-sectional study of consecutive patients diagnosed with RA-ILD. Demographic, analytical, respiratory functional and evolution characteristics were analyzed to evaluate the predictors of progression and mortality. 106 patients were included. The multivariate analysis showed that the diagnostic delay was an independent predictor of mortality (HR 1.11, CI 1.01-1.23, p = 0.035). Also, age (HR 1.33, 95% CI 1.09-1.62, p = 0.0045), DLCO (%) (HR 0.85, 95% CI 0.73-0.98, p = 0.0246), and final SatO2 (%) in the 6MWT (HR 0.62, 95% CI 0.39-0.99, p = 0.0465) were independent predictor variables of mortality, as well as GAP index (HR 4.65, 95% CI 1.59-13.54, p = 0.0051) and CPI index (HR 1.12, 95% CI 1.03-1.22, p = 0.0092). The withdrawal of MTX or LFN after ILD diagnosis was associated with disease progression in the COX analysis (HR 2.18, 95% CI 1.14-4.18, p = 0.019). This is the first study that highlights the diagnostic delay in RA-ILD is associated with an increased mortality just like happens in IPF.

Repeated Pulses of Methyl-Prednisolone in Adults Hospitalized With COVID-19 Pneumonia and Acute Respiratory Distress Syndrome: A Preliminary Before-After Study (CortiCOVID Study).

Introduction: The use of systemic corticosteroids in severely ill patients with coronavirus disease 2019 (COVID-19) is controversial. We aimed to evaluate the efficacy and safety of corticosteroid pulses in patients with COVID-19 pneumonia. Methods: A quasi-experimental study, before and after, was performed in a tertiary referral hospital, including admitted patients showing COVID-19-associated pneumonia. The standard treatment protocol included targeted COVID-19 antiviral therapy from 23rd March 2020, and additionally pulses of methylprednisolone from 30th March 2020. The primary outcome was a composite endpoint combining oro-tracheal intubation (OTI) and death within 7 days. Results: A total of 24 patients were included. Standard of care (SOC) (before intervention) was prescribed in 14 patients, while 10 received SOC plus pulses of methylprednisolone (after intervention). The median age of patients was 64.5 years and 83.3% of the patients were men. The primary composite endpoint occurred in 13 patients (92.9%) who received SOC vs. 2 patients (20%) that received pulses of methylprednisolone (odds ratio, 0.02; 95% confidence interval, 0.001 to 0.25; p = 0.019). Length of hospitalization in survivors was shorter in the corticosteroids group (median, 14.5 [8.5-21.8] days vs. 29 [23-31] days, p = 0.003). There were no differences in the development of infections between both groups. There were 3 deaths, none of them in the corticosteroids group. Conclusions: In patients with severe pneumonia due to COVID-19, the administration of methylprednisolone pulses was associated with a lower rate of OTI and/or death and a shorter hospitalization episode.

Introducción: El uso de corticosteroides sistémicos en pacientes gravemente enfermos por enfermedad coronavírica de 2019 (covid-19) es controvertido. Nuestro objetivo fue evaluar la eficacia y la seguridad de los pulsos de corticoesteroides en los pacientes con neumonía por covid-19. Métodos: Se realizó un ensayo cuasiexperimental, tipo antes y después, en un hospital terciario de referencia que incluyó a pacientes ingresados por neumonía asociada a covid-19. El protocolo de tratamiento estándar incluía un tratamiento antiviral dirigido contra el virus de la covid-19 desde el 23 de marzo de 2020 y añadió pulsos de metilprednisolona desde el 30 de marzo de 2020. El resultado primario fue un criterio combinado compuesto por la intubación orotraqueal y el fallecimiento durante los siguientes siete días. Resultados: Se incluyó un total de 24 pacientes. El protocolo de tratamiento (antes de la intervención) se prescribió en 14 pacientes, mientras que 10 recibieron el protocolo de tratamiento además de los pulsos de metilprednisolona (después de la intervención). La edad media de los pacientes fue de 64,5 años y el 83,3% de los pacientes eran hombres. El resultado combinado primario tuvo lugar en 13 pacientes (92,9%) que recibieron el protocolo de tratamiento frente a 2 pacientes (20%) que recibieron los pulsos de metilprednisolona (odds ratio = 0,02; intervalo de confianza del 95% = 0,001-0,25; p = 0,019). La duración de la hospitalización en los supervivientes fue más corta en el grupo que recibió corticoesteroides (media = 14,5 [8,5-21,8] días frente a 29 [23-31] días, p = 0,003). No hubo diferencias en el desarrollo de infecciones entre ambos grupos. Hubo tres fallecimientos, ninguno de ellos en el grupo que recibió corticoesteroides. Conclusiones: En los pacientes con neumonía grave por covid-19, la administración de pulsos de metilprednisolona se asoció a unas tasas menores de intubación orotraqueal y/o muerte y a episodios de hospitalización más cortos.

Cuidados de enfermería en el niño con traqueostomía / Nursing care in children with tracheostomy

La traqueostomía es una técnica sencilla. Las indicaciones de esta técnica han variado a lo largo de los años; actualmente la causa más frecuente es la necesidad de ventilación prolongada. Existen diferentes modelos de cánulas, que se adaptan a las necesidades de cada paciente. Los niños con traqueostomía requieren unos cuidados específicos por parte de las enferme-ras. Debemos conocer el manejo de las complicaciones como la obstrucción de la cánula o la de canulación accidental. Dichas complicaciones son potencial-mente prevenibles con cuidados adecuados por parte de las enfermera

Tracheostomy is a very simple technique. Indications for tracheostomy have chan-ged over the years; today the most com-mon indication is prolonged ventilation.There are different types of tracheostomy tubes, that suit with each patient. Children with tracheostomy need specific nursing care. We need to know the ma-nagement of the complications such as cannula obstruction and decannulation. These complications are potentially pre-venible with adequate nursing care

Papel de los polimorfismos de la GST (Glutation-S-transferasa) en la susceptibilidad genética a desarrollar asma bronquial en una población de asmáticos andaluces / The role of GST (Glutathione S-transferases) polymorphisms in the genetic susceptibility to develop bronchial asthma in a population of andalusian asthmatics

OBJETIVO: Analizar la presencia de variaciones genéticas en las enzimas de detoxificación GST (Glutation-S-transferasa), concretamente las enzimas GSTM1, GSTT1 y GSTP1.5, en pacientes con asma bronquial y la posible asociación con parámetros clínicos, funcionales e inflamatorios. METODOLOGÍA: Se incluyeron pacientes en seguimiento por asma bronquial junto a un grupo control de individuos no asmáticos. Se analizaron, junto al análisis genético, los parámetros clínicos, incluido ACT, grado de gravedad y grado de control, parámetros funcionales y de inflamación (FeNO-Fracción espirada de óxido nítrico). El estudio genético se realizó mediante extracción del ADN celular de sangre periférica y su posterior análisis por técnicas de biología molecular (PCR: reacción en cadena de la polimerasa y electroforesis en geles de agarosa) en el Instituto de Biomedicina de Sevilla (IBIS). RESULTADOS: Se estudiaron 256 asmáticos, y un grupo control de 40 pacientes. El mayor porcentaje de pacientes presentaban un asma moderada (53%), frente al 23% de asma leve y 24% de asma grave. Según el grado de control en el momento de la inclusión, presentaban buen control el 46% de la serie, mal control el 30% y un 24% de los pacientes estaban parcialmente controlados. En cuanto a la presencia de los polimorfismos: el polimorfismo GSTM1 presentaba genotipo positivo (sin delección) en el 34% de la serie, frente al 65,9% que presentaban genotipo nulo (deleccionadoausencia de la enzima de depuración); en el caso del polimorfismo GSTT1, el 75,6% presentaban genotipo positivo y 24,4% genotipo nulo. De las tres posibilidades polimórficas del GSTP1.5 (34% presentaban genotipo A/A; 48,8% genotipo A/G y 17,1% genotipo G/G). Encontramos un asociación estadísticamente significativa (p = 0,017) entre la presencia del alelo Ile/Ile (A/A) del polimorfismo GSTP1.5 y las mujeres asmáticas, así como con niveles más bajos de FeNO. CONCLUSIONES: no encontramos diferencias estadísticamente significativas entre la presencia de los polimorfismos GSTM1, GSTT1 con ninguno de los parámetros clínicos y funcionales analizados. En cuanto a la presencia del polimorfismo GSTP1.5, encontramos relación estadísticamente significativa con la presencia de asma bronquial en la población de mujeres, concretamente con la presencia del genotipo A/A homocigoto y que a su vez presentaba valores más bajos de FeNO

OBJECTIVE: to analyze the presence of genetic variations in the GST (glutathione S-transferase) detoxification enzymes, specifically the GSTM1, GSTT1 and GSTP1.5 enzymes, in patients with bronchial asthma and their possible association with clinical, functional and inflammatory parameters. METHODS: Patients undergoing follow-up for bronchial asthma were included along with a control group of non-asthmatic individuals. In addition to genetic analysis, the clinical parameters including ACT, degree of severity and degree of control, and functional and inflammation parameters (FeNO, fractional exhaled nitric oxide) were analyzed. The genetic study was done by extracting cellular DNA from peripheral blood which was then analyzed using molecular biology techniques (PCR: polymerase chain reaction and agarose gel electrophoresis) at the Instituto de Biomedicina de Sevilla (IBIS). RESULTS: 256 asthmatic patients and a control group of 40 patients were studied. The majority of patients presented with moderate asthma (53%), compared to 23% with mild asthma and 24% with severe asthma. According to degree of control upon inclusion, 46% of patients in the series had good control, 30% poor control, and 24% of patients were partially controlled. With regard to the presence of polymorphisms: the GSTM1 polymorphism showed a positive genotype (without deletion) in 34% of patients in the series, compared to 65.9% who showed a null genotype (deleted-absent purification enzyme); as for the GSTT1 polymorphism, 75.6% of patients showed a positive genotype and 24.4% a null genotype. Of the three polymorphic possibilities for GSTP1.5, 34% showed the AA genotype, 48.8% the AG genotype and 17.1% the GG genotype. We found a statistically significant association (p = 0.017) between the Ile/ Ile (AA) allele of the GSTP1.5 polymorphism and asthmatic women, as well as lower FeNO levels. CONCLUSIONS: We did not find statistically significant differences between the presence of the GSTM1 and GSTT1 polymorphisms and any of the analyzed clinical or functional parameters. With regard to the presence of the GSTP1.5 polymorphism, we found a statistically significant relationship with the presence of bronchial asthma in the female population, specifically with the presence of the homozygous AA genotype and the fact they also showed lower FeNO values

Is the bronchodilator test an useful tool to measure asthma control?

INTRODUCTION: Asthma control includes the control of symptoms and future risk. We sought to evaluate the usefulness of the degree of spirometric reversibility of the forced expiratory volume in one second (FEV1) as the target parameter of control. METHODOLOGY: Patients with bronchial asthma were followed up for one year. The clinical, functional, inflammatory and control parameters of the asthma were collected. The area under the curve (AUC) was estimated to establish the cutoff point of the post-bronchodilator FEV1 reversibility in relation to non-control asthma. In the univariate analysis, the differences between groups were studied based on the degree of estimated reversibility. Factors with a significance <0.1 were included in the multivariate analysis by binary logistic regression. RESULTS: A total of 407 patients with a mean age of 38.1 ± 16.7 years were included. When the patients were grouped into controlled and non-controlled groups, compared with post-bronchodilator FEV1 reversibility, the cutoff point obtained for the non-controlled group was ≥10% (sensitivity: 65.8%, specificity: 48.4%, positive predictive value: 69.5%, and AUC: 0.619 [0.533-0.700], p < 0.01). In the year-long follow-up of this group (post-bronchodilator FEV1 ≥10), an increased use of relief medication was observed, along with a significantly progressive drop in post-bronchodilator FEV1 and post-bronchodilator FEV1/FVC (forced expiratory volume in one second/forced vital capacity). CONCLUSIONS: Spirometric reversibility can be useful in assessing control in asthmatic patients and can predict future risk parameters. The cutoff point related to the non-control of asthma found in our work was ≥10%.

Predictors of 10-year smoking abstinence in smokers abstinent for 1 year after treatment.

AIMS: To identify factors predicting long-term relapse to smoking in people attending smoking treatment services who have maintained at least 1 year abstinence. DESIGN: Observational, prospective study with multiple logistic regression used to model predictors of relapse between 1 and 10 years from cessation using variables measured pre-cessation. SETTING AND PARTICIPANTS: Among smokers receiving behavioural support for cessation in a clinic in Spain, in some cases with nicotine patches or bupropion, 366 had remained abstinent after 1 year of follow-up and were included into the study. MEASUREMENTS: Predictive measures (disease history, psychological disorder, age of starting smoking, years of smoking, cigarette dependence and smoking cessation treatment used) were obtained at the time of the quit attempt, and 'failure' (defined as reported smoking, loss to follow-up, died or an expired air carbon monoxide reading of > 5 parts per million) was assessed 10 years later. FINDINGS: At follow-up, abstinence status was confirmed in 50.5% (n = 185) of participants, while 21.0% (n = 77) reported that they had resumed smoking, and 28.5% (n = 104) were lost to follow-up (also counted as having resumed smoking). In the multiple regression model, the main factor that predicted relapse had a psychological disorder (odds ratio = 1.85, 95% confidence interval = 1.13-3.05; P < 0.02). CONCLUSIONS: Having a psychological disorder at the time of stopping smoking is a risk factor for relapse to smoking, even after more than 1 year of abstinence.

Fibrosing mediastinitis mimicking sarcoidosis.

Fibrosing mediastinitis (FM), also called sclerosing mediastinitis or mediastinal fibrosis, is a rare disease characterized by excessive fibrotic reaction in the mediastinum and may compromise the airway, the great vessels and other mediastinal structures, with a morbidity directly related to the location and extent of fibrosis. The cause is not always known but is often the result of a granulomatous disease, most often the histoplasmosis. We report a 43-year-old woman with a history of tuberculosis infection 23 years ago. She attended the pulmonology clinic for cough and dyspnea. Physical examination revealed jugular venous distention at 90°. In computed tomography scan of the chest with contrast (c/c), we observed a mediastinal nodal cast provoking cava compression and obliteration of main and intermediary right lobar bronchus. The pathological examination was FM.

Rivaroxaban for the treatment of venous thromboembolism. A "real-life" perspective in 103 patients.

INTRODUCTION: Randomized clinical trials have demonstrated non-inferiority of rivaroxaban compared with vitamin K antagonists (VKAs) in the treatment of venous thromboembolism (VTE). Our objective was to analyze in real life, tolerance, recurrence, bleeding and adverse events of rivaroxaban in patients with acute symptomatic VTE. MATERIAL AND METHODS: Open follow-up study of a cohort of patients aged 18 and over diagnosed with deep vein thrombosis (DVT) and/or pulmonary embolism (PE) treated with rivaroxaban from December 2011 to January 2014. RESULTS: The total number of patients treated with rivaroxaban was 103. The mean age was 58+/-17 years. The most frequent co-morbidities were: hypertension (30.0%), dyslipidemia (23.3%) and respiratory disease (25.2%). The type of thromboembolic event treated was: DVT (64.1%), PE (18.4%), DVT+PE (17.5%). Of the rivaroxaban-treated patients, 30% did so from the initial anticoagulant therapy and the other 70% in long-term or extended anticoagulant therapy. The median time of treatment with rivaroxaban was 6 months [corrected]. There was one recurrence and no deaths occurred. Six patients had bleeding, one of which was severe. CONCLUSIONS: Rivaroxaban provides a therapeutic alternative in a group of patients with VTE with advantages over VKAs, because of the convenience in dosing, lack of requirements for periodic monitoring and limited interaction with other drugs.

La escala predictiva de Khorana en pacientes con enfermedad tromboembólica venosa y cáncer / Predictive Khorana's model in patients with venous thromboembolic disease and cancer

Fundamento y objetivo: El modelo predictivo de Khorana se desarrolló para estratificar el riesgo de enfermedad tromboembólica en pacientes con cáncer y en tratamiento con quimioterapia y, por tanto, identificar a aquellos que podrían beneficiarse de tromboprofilaxis. Analizar los resultados de la aplicación del modelo predictivo de Khorana en una cohorte de pacientes con cáncer y que fueron diagnosticados de trombosis venosa profunda (TVP). Pacientes y métodos: Análisis retrospectivo de las características pronósticas del modelo de Khorana en 122 pacientes con cáncer y TVP, basado en una recogida prospectiva de datos. Resultados: Se catalogó al 79% como pacientes de riesgo bajo e intermedio, y al 21% como de alto riesgo. La escala de Khorana tuvo una sensibilidad y exactitud pronóstica del 20,8% (intervalo de confianza del 95% [IC 95%]: 14,6-28,7) y una proporción de falsos negativos de 79,2% (IC 95%: 1,3-85,4). Conclusiones: La aplicación de este modelo en nuestros pacientes resultaría insuficiente como única herramienta para identificar a los enfermos con cáncer que deberían ser tratados con tromboprofilaxis. El uso de biomarcadores junto a modelos clínicos parece ser la mejor estrategia costo-efectivas para identificar a pacientes candidatos al tratamiento profiláctico. Estudios amplios, prospectivos, randomizados y con placebo deberían decidir si esta estrategia es la más válida (AU)

Control ambulatorio de los pacientes con trombosis venosa profunda y cáncer: estudio de seguridad, costes e impacto presupuestario / Outpatient management of patients with deep vein thrombosis and cancer: A study of safety, cost and budget impact

Fundamento y objetivo: Realizamos un estudio sobre seguridad, costes comparados y análisis de impacto presupuestario del tratamiento ambulatorio de pacientes con cáncer y trombosis venosa profunda (TVP) frente al tratamiento hospitalario. Material y métodos: Estudio observacional y prospectivo de pacientes con neoplasia conocida y diagnosticados de TVP desde 2003 hasta 2007. Las variables de resultados fueron mortalidad, recidivas y hemorragias a un mes. Realizamos un análisis económico para evaluar el coste comparado de los pacientes tratados ambulatoriamente frente al procedimiento habitual. Resultados: Se incluyeron 317 pacientes, 55 (17%) con cáncer. La edad media (DE) de los pacientes fue de 63 (11) años. Las complicaciones a un mes fueron: 2 sangrados, 2 recidivas y 6 muertes. De todos los pacientes, solo 7 (13,7%) necesitaron ingreso hospitalario. Todas las muertes excepto una fueron debidas a la progresión de su enfermedad de base. Cuando realizamos el análisis económico observamos que el tratamiento ambulatorio es 6 veces menos costoso que el hospitalario, lo que implicaría una reducción de costes de un 85%. Conclusiones: El tratamiento ambulatorio a través de una consulta monográfica de los pacientes con cáncer y TVP es seguro y podría ahorrar importantes recursos económicos (AU)

Background and objective: This is a safety and cost comparison study with an analysis of budgetary impact of ambulatory management of patients with cancer and deep vein thrombosis (DVT) compared with hospital management. Material and methods: Prospective observational study of patients with known malignancy and diagnosed with DVT from 2003 to 2007. The outcome variables were mortality, relapse and bleeding in one month. We conducted an economic analysis to evaluate the comparative cost of ambulatory patients. Results: Three hundred and seventeen patients, 55 (17%) had cancer. The mean age of patients was 63±11 years. There were 2 hemorrhagic events, 2 recurrences and 6 deaths in one month of follow-up. Of all patients, only 7 (13,7%) required hospitalization. All but one deaths were due to progression of the underlying disease. Economic analysis concluded that outpatient management is 6 times less expensive than hospital management, which would imply a cost reduction of 85%. Conclusions: Specialized outpatient treatment of cancer patients with DVT is safe and could save significant financial resources (AU)

Hipertensión pulmonar tromboembólica crónica debida a trombosis venosa profunda de miembro superior por síndrome del desfiladero torácico / Chronic Thromboembolic Pulmonary Hypertension Due to Upper-Extremity Deep Vein Thrombosis Caused by Thoracic Outlet Syndrome

Se presenta el caso de una mujer de 20 años diagnosticada de tromboembolismo pulmonar (EP) y trombosis de la vena subclavia derecha atribuible a la estasis provocada por la prominencia clavicular derecha. En el seguimiento a los 10 meses la paciente desarrolló una hipertensión pulmonar tromboembólica crónica (HPTEC), instaurándose tratamiento con un antagonista dual del receptor de endotelina. Se han descrito muy pocos casos de trombosis venosa profunda de miembro superior debidos a alteraciones anatómicas. Lo excepcional del caso es que, además, la paciente desarrolló una hipertensión pulmonar postembólica crónica, cuya incidencia se estima del 0,5% del total de los EP sintomáticos(AU)

We report on a 20 year-old woman diagnosed with pulmonary embolism (PE) and right subclavian vein thrombosis attributable to stasis caused by right clavicular prominence. At the 10-months follow-up, the patient had developed chronic thromboembolic pulmonary hypertension (CTEPH), and treatment was begun with a dual endothelin receptor antagonist. Very few cases of deep venous thrombosis of upper limb have been reported in relation to anatomical abnormalities. This case is also exceptional because the patient developed a chronic thromboembolic pulmonary hypertension, whose incidence is estimated at 0.5% of all symptomatic PE(AU)
