RESUMO
INTRODUCTION: Nebulized hypertonic saline (HS) improves quality of life and reduces exacerbations in patients with cystic fibrosis. It is unknown if it would offer the same benefits in other hypersecretory pathologies. METHODS: Retrospective observational study. Patients who passed the tolerance test and started HS 5.8% with one year of follow-up were included. Clinical and healthcare parameters were quantified in the year before and after the start of treatment. RESULTS: 101 patients, 60.4% women, 65years (95%CI: 62.4-67.9): 82 (81.2%) bronchiectasis, 6 (5.9%) COPD, 2 (2%) asthma, 1 (1%) ILD, and 10 (9.9%) other causes. There was a reduction in bronchorrhea (91.1% vs 75.2%), recurrent infections (57.4% vs 22.8%) and cycles of antibiotic therapy (1.54 vs 0.55), as well as an increase in FEV1 (1881ml vs. 1942ml) and a decrease in visits to primary care (2.94 vs. 1.1), emergencies (0.36 vs. 0.17) and hospitalizations (0.17 vs. 0.17). 06). 73 patients (72.3%) presented an adequate tolerance. CONCLUSION: Nebulization of HS 5.8% in patients with bronchial hypersecretion is safe and has a remarkable clinical and healthcare impact.

INTRODUCTION: New tools such as cryobiopsy of mediastinal lymph nodes (cryoEBUS) have been described to improve the diagnostic usefulness of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). The literature suggests that this novel procedure could be associated with greater diagnostic usefulness than conventional EBUS-TBNA. METHODS: To develop a systematic analysis and meta-analysis on the diagnostic diagnostic yield and safety of cryobiopsy of hilar and mediastinal adenopathies compared to EBUS-TBNA. RESULTS: Seven studies that had included a total of 555 patients were considered in this review, with 365 (65.7%) of these patients having an etiology of malignant lymph node involvement. The overall diagnostic usefulness of cryoEBUS was higher compared to EBUS-TBNA (92% vs. 80%). However, when the results were analysed according to the specific aetiologies of the adenopathies, cryoEBUS was especially useful in cases of lymphomas or non-pulmonary carcinomas (83% vs. 42%) and in cases that were benign (87% vs. 60.1%), with no significant differences being found in specific cases of lung cancer. For lymphoma, cryoEBUS was diagnostic in 87% of cases compared to 12% for EBUS-TBNA and in addition, also allowed the characterisation of every lymphoma subtype. Genetic studies and immunohistochemical determination of PD-L1 was possible in almost all (97%) of the samples obtained by cryoEBUS, while this was only possible in 79% of those obtained by EBUS-TBNA. The most frequent complication was light bleeding, which was described in up to 85% of cases in some series. CONCLUSION: CryoEBUS could represent a promising technique in the diagnostic algorithm used for mediastinal and hilar involvement. Although cryoEBUS did not significantly improve the diagnosis of lung cancer compared to EBUS-TBNA, the results were significantly better in patients with benign pathologies and other tumour types, including lymphomas. In addition, it seems that the samples obtained by cryoEBUS better defined the histological subtypes of lymphoma and allowed complete molecular characterisation in cases of lung cancer. The technique has proven to be safe and no serious complications were described after the procedure.

Introduction: Lung ultrasound (LUS) has proven to be a more sensitive tool than radiography (X-ray) to detect alveolar-interstitial involvement in COVID-19 pneumonia. However, its usefulness in the detection of possible pulmonary alterations after overcoming the acute phase of COVID-19 is unknown. In this study we proposed studying the utility of LUS in the medium- and long-term follow-up of a cohort of patients hospitalized with COVID-19 pneumonia. Materials and methods: This was a prospective, multicentre study that included patients, aged over 18 years, at 3 ± 1 and 12 ± 1 months after discharge after treatment for COVID-19 pneumonia. Demographic variables, the disease severity, and analytical, radiographic, and functional clinical details were collected. LUS was performed at each visit and 14 areas were evaluated and classified with a scoring system whose global sum was referred to as the "lung score." Two-dimensional shear wave elastography (2D-SWE) was performed in 2 anterior areas and in 2 posterior areas in a subgroup of patients. The results were compared with high-resolution computed tomography (CT) images reported by an expert radiologist. Results: A total of 233 patients were included, of whom 76 (32.6%) required Intensive Care Unit (ICU) admission; 58 (24.9%) of them were intubated and non-invasive respiratory support was also necessary in 58 cases (24.9%). Compared with the results from CT images, when performed in the medium term, LUS showed a sensitivity (S) of 89.7%, specificity (E) 50%, and an area under the curve (AUC) of 78.8%, while the diagnostic usefulness of X-ray showed an S of 78% and E of 47%. Most of the patients improved in the long-term evaluation, with LUS showing an efficacy with an S of 76% and E of 74%, while the X-ray presented an S of 71% and E of 50%. 2D-SWE data were available in 108 (61.7%) patients, in whom we found a non-significant tendency toward the presentation of a higher shear wave velocity among those who developed interstitial alterations, with a median kPa of 22.76 ± 15.49) versus 19.45 ± 11.39; p = 0.1). Conclusion: Lung ultrasound could be implemented as a first-line procedure in the evaluation of interstitial lung sequelae after COVID-19 pneumonia.
RESUMO
In recent years, personalized or precision medicine has made effective inroads into the management of diseases, including respiratory diseases. The route to implementing this approach must invariably start with the identification and validation of biological biomarkers that are closely related to the diagnosis, treatment, and prognosis of respiratory patients. In this respect, biological biomarkers of greater or lesser reliability have been identified for most respiratory diseases and disease classes, and a large number of studies are being conducted in the search for new indicators. The aim of this review is to update the reader and to analyze the existing scientific literature on the existence and diagnostic, therapeutic, and prognostic validity of the most important biological biomarkers in the main respiratory diseases, and to identify future challenges in this area.

Background: The current cost of treatment of malignant pleural effusion (MPE) with an indwelling pleural catheter (IPC) is unclear. Objective: We propose a review of the scientific evidence on the cost and effectiveness of this therapeutic option. Methods: Systematic review of the literature on the cost and effectiveness of the treatment of MPE by IPC, according to the PRISMA methodology and quality according to the scientific guidelines. Results: A total of 4 articles, 152 patients, and 159 IPCs were included. The use of IPC was associated with improvement in symptoms and quality of life. The most common complications were infections (empyema in 20.9% of patients and cellulitis in 17.3%); 9% of cases were hospitalized due to complications, and <2% required subsequent procedures. The average cost of IPC (set/drainage bottles) ranged from 2,025.6 to 1,200.5 if it was placed on an outpatient basis, 1,100 if survival was <6 weeks, and 4,028 in patients with mesothelioma. Complications increased the cost, and taking into account follow-up visits, additional tests, and days of admission for complications, the cost was >5,000. Compared with pleurodesis, the cost of IPC was significantly lower when patient survival was <14 weeks, but not when survival was longer or home care was required. Conclusions: The use of IPC is associated with good control of MPE and seldom requires many subsequent procedures; however, it is also associated with a certain rate of complications, which may increase costs. However, ambulatory management may help reduce costs, which are directly related to the type of tumor, the duration of survival, and the need for specialized treatment.

INTRODUCTION: There is debate as to whether lung-ultrasound (LUS) can replace lung-auscultation (LA) in the assessment of respiratory diseases. METHODOLOGY: The diagnostic validity, safety, and reliability of LA and LUS were analyzed in patients admitted in a pulmonary ward due to decompensated obstructive airway diseases, decompensated interstitial diseases, and pulmonary infections, in a prospective study. Standard formulas were used to calculate the diagnostic sensitivity, specificity, and accuracy. The interobserver agreement with respect to the LA and LUS findings was evaluated based on the Kappa coefficient (á´). RESULTS: A total of 115 patients were studied. LUS was more sensitive than the LA in evaluating pulmonary infections (93.59% vs. 77.02%; p = 0.001) and more specifically in the case of decompensated obstructive airway diseases (95.6% vs. 19.10%; p = 0.001). The diagnostic accuracy of LUS was also greater in the case of pulmonary infections (75.65% vs. 60.90%; p = 0.02). The sensitivity and specificity of the combination of LA and LUS was 95.95%, 50% in pulmonary infections, 76.19%, 100% in case of decompensated obstructive airway diseases, and (100%, 88.54%) in case of interstitial diseases. (á´) was 0.71 for an A-pattern, 0.73 for pathological B-lines, 0.94 for condensations, 0.89 for pleural-effusion, 0.63 for wheezes, 0.38 for rhonchi, 0.68 for fine crackles, 0.18 for coarse crackles, and 0.29 for a normal LA. CONCLUSIONS: There is a greater interobserver agreement in the interpretation of LUS-findings compared to that of LA-noises, their combined use improves diagnostic performance in all diseases examined.

En los últimos años la llamada «medicina personalizada o de precisión» ha irrumpido con fuerza en el manejo de las enfermedades, entre ellas las respiratorias. La posibilidad de implantar esta forma de trabajar pasa indefectiblemente por el hallazgo y validación de biomarcadores biológicos que se relacionen bien con el diagnóstico, tratamiento o pronóstico de los pacientes respiratorios. En este sentido, la mayoría de enfermedades respiratorias o grupo de las mismas ya cuentan con biomarcadores biológicos de mayor o menor fiabilidad, y se están realizando un gran número de estudios en busca de nuevos de estos indicadores.

OBJETIVO: La evidencia disponible sobre la rentabilidad diagnóstica y la seguridad de la criobiopsia pleural (CB) está basada en una serie de estudios que presentan casuísticas limitadas y diferentes diseños. Un análisis agrupado de los mismos podría mejorarla y aportar una visión global de esta novedosa técnica. METODOLOGÍA: Revisión sistemática y metaanálisis de los estudios publicados en los que se incluían resultados sobre rendimiento y seguridad diagnóstica de la CB pleural comparados con la realizada con pinzas flexibles convencionales. Se evaluó la heterogeneidad del análisis determinando el índice I2 y la calidad de los estudios mediante la herramienta QUADAS-2. RESULTADOS: Para la evaluación final se incluyeron 7 trabajos con 356 pacientes. En el 55,6% el derrame pleural fue de etiología maligna, 61,1% de ellos cáncer de pulmón. La rentabilidad diagnóstica de la CB pleural fue del 95% (IC 95% 92-97) frente al 91% (IC 95% 87-94) con las pinzas flexibles convencionales (p = 0,019). Se describió sangrado leve en el 67% (IC 95% 62-72) de las CB frente al 85% (IC 95% 79-90) de las realizadas con pinzas flexibles convencionales (p < 0,001). El tamaño de las muestras de CB fue superior y el porcentaje de artefactos menor. No fue posible realizar un análisis agrupado en la evaluación de la detección de alteraciones moleculares. La heterogeneidad observada fue moderada-alta, aunque la calidad de los estudios fue aceptable. CONCLUSIONES: La CB pleural es una técnica segura y con elevada rentabilidad para el diagnóstico etiológico del derrame pleural, obteniéndose muestras de mayor tamaño con menos artefactos. Son necesarios más estudios sobre determinaciones moleculares
OBJECTIVE: Current evidence on the diagnostic yield and safety of pleural cryobiopsy (CB) is based on a series of heterogeneous studies with limited cohorts. A pooled analysis of these studies could improve the evidence and contribute to a better understanding of this new technique. METHODOLOGY: We performed a systematic review and meta-analysis of published studies that included data on the yield and diagnostic safety of pleural CB compared with procedures performed using conventional flexible forceps. The heterogeneity of the analysis was evaluated by determining the I2 index, while study quality was measured with the QUADAS-2 tool. RESULTS: Seven studies involving 356 patients were used for the final evaluation. In 55.6%, the etiology of the pleural effusion was malignant, 61.1% of which were lung cancer. The diagnostic yield of pleural CB was 95% (95% CI 92-97) vs. 91% (95% CI 87-94) with conventional flexible forceps (P = .019). Mild bleeding was reported in 67% of CB procedures (95% CI 62-72) compared with 85% of conventional flexible forceps procedures (95% CI 79-90) (P < .001). CB specimens were larger, and fewer artifacts were detected. A pooled analysis of the detection of molecular changes could not be performed. Heterogeneity was moderate to high, although the quality of the studies was acceptable. CONCLUSIONS: Pleural CB is a safe technique with a high yield for etiological diagnosis of pleural effusion, and larger specimens with fewer artifacts are obtained. Molecular determinations should be investigated in more deph
