RESUMO
Exacerbations of chronic obstructive pulmonary disease (COPD) are associated with loss of lung function, poor quality of life, loss of exercise capacity, risk of serious cardiovascular events, hospitalization, and death. However, patients underreport exacerbations, and evidence suggests that unreported exacerbations have similar negative health implications for patients as those that are reported. Whilst there is guidance for physicians to identify patients who are at risk of exacerbations, they do not help patients recognise and report them. Newly developed tools, such as the COPD Exacerbation Recognition Tool (CERT) have been designed to achieve this objective. This review focuses on the underreporting of COPD exacerbations by patients, the factors associated with this, the consequences of underreporting, and potential solutions.

BACKGROUND: Longitudinal cohort data of patients with tuberculosis (TB) and coronavirus disease 2019 (COVID-19) are lacking. In our global study, we describe long-term outcomes of patients affected by TB and COVID-19. METHODS: We collected data from 174 centres in 31 countries on all patients affected by COVID-19 and TB between 1 March 2020 and 30 September 2022. Patients were followed-up until cure, death or end of cohort time. All patients had TB and COVID-19; for analysis purposes, deaths were attributed to TB, COVID-19 or both. Survival analysis was performed using Cox proportional risk-regression models, and the log-rank test was used to compare survival and mortality attributed to TB, COVID-19 or both. RESULTS: Overall, 788 patients with COVID-19 and TB (active or sequelae) were recruited from 31 countries, and 10.8% (n=85) died during the observation period. Survival was significantly lower among patients whose death was attributed to TB and COVID-19 versus those dying because of either TB or COVID-19 alone (p<0.001). Significant adjusted risk factors for TB mortality were higher age (hazard ratio (HR) 1.05, 95% CI 1.03-1.07), HIV infection (HR 2.29, 95% CI 1.02-5.16) and invasive ventilation (HR 4.28, 95% CI 2.34-7.83). For COVID-19 mortality, the adjusted risks were higher age (HR 1.03, 95% CI 1.02-1.04), male sex (HR 2.21, 95% CI 1.24-3.91), oxygen requirement (HR 7.93, 95% CI 3.44-18.26) and invasive ventilation (HR 2.19, 95% CI 1.36-3.53). CONCLUSIONS: In our global cohort, death was the outcome in >10% of patients with TB and COVID-19. A range of demographic and clinical predictors are associated with adverse outcomes.

Since the first description of pulmonary circulation in the 16th century, the knowledge of the complex interaction between the heart and lungs has greatly improved. Hypoxemia plays a classical role in the development of complications such as pulmonary hypertension and right ventricle (RV) dysfunction in patients presenting with chronic obstructive pulmonary disease (COPD). However, more recent results have revealed the presence of RV vascular structural and functional changes even in patients with mild COPD, without hypoxemia or pulmonary hypertension at rest. Compared to the left ventricle, the anatomy of the RV is unique and complex, which makes its assessment more difficult during routine exams. Therefore, it is common that very little attention is paid to its study. In this article, the physiological aspects of pulmonary circulation and the RV, as well as their impairment in COPD patients, are presented. In addition, important aspects of the recommendations for RV assessment using echocardiography are approached and studies that used other complementary exams to evaluate RV structure and function are revisited. Finally, the findings of studies that assessed the impact of RV dysfunction in the prognosis of patients with COPD are described.

BACKGROUND: Depression is a common comorbidity among patients with Chronic Obstructive Pulmonary Disease (COPD) and has a significant impact on the course of the disease. The aim of this study is to determine association between COPD Assessment Test (CAT) and major depression among clinically stable out-patient COPD subjects with mild hypoxemia. METHODS: Case-control study. Cases were 30 patients with major depression and controls were 30 patients without depression. Major depression was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders criteria by a psychiatric evaluation. All possible predictive variables were included in a multivariate logistic regression model to assess the association between major depression and each independent variable, while controlling for the sleep parameters. RESULTS: CAT score >20 was associated with major depression (OR 7.88; 95% CI 1.96 - 31.7; p = 0.004). CONCLUSION: CAT score >20 was associated with major depression, suggesting CAT as a predictor variable of major depression among COPD patients with mild hypoxemia, and indicating that an additional specific evaluation for the presence of major depression should be done.

Rheumatoid arthritis (RA) is an autoimmune disease characterised by the destruction of articular cartilage and bone damage. The chronic treatment of RA patients causes a higher susceptibility to infectious diseases such as tuberculosis (TB); one-third of the world's population is latently infected (LTBI) with Mycobacterium tuberculosis (Mtb). The tuberculin skin test is used to identify individuals LTBI, but many studies have shown that this test is not suitable for RA patients. The goal of this work was to test the specific cellular immune responses to the Mtb malate synthase (GlcB) and heat shock protein X (HspX) antigens of RA patients and to correlate those responses with LTBI status. The T-helper (Th)1, Th17 and Treg-specific immune responses to the GlcB and HspX Mtb antigens were analysed in RA patients candidates for tumour necrosis factor-α blocker treatment. Our results demonstrated that LTBI RA patients had Th1-specific immune responses to GlcB and HspX. Patients were followed up over two years and 14.3% developed active TB. After the development of active TB, RA patients had increased numbers of Th17 and Treg cells, similar to TB patients. These results demonstrate that a GlcB and HspX antigen assay can be used as a diagnostic test to identify LTBI RA patients.

OBJECTIVE: To assess prescription patterns for short-acting b2 agonists (SABAs) and other asthma medications in asthma patients treated by specialists and participating in the SABA use IN Asthma (SABINA) study in Brazil. METHODS: This was an observational, cross-sectional study conducted at five sites in different regions of Brazil. The primary endpoints were to record SABA prescriptions and obtain data on over-the-counter (OTC) SABA purchases at the pharmacy. RESULTS: Data on 218 asthma patients were analyzed. Of those 218 patients, 80.3% were prescribed SABAs in addition to their maintenance therapy, with a mean of 11.2 SABA canisters in the previous 12 months. Of those patients, 71.4% were prescribed ≥ 3 canisters and 42.2% were prescribed ≥ 10 canisters. None of the patients were prescribed SABA monotherapy. A total of 14.2% of the patients reported purchasing SABAs OTC at a pharmacy without a prescription. Of those, 48.4% purchased ≥ 3 SABA canisters. A fixed-dose combination of an inhaled corticosteroid and a long-acting b2 agonist was prescribed to 95.0% of the patients. In the year before the study visit, 45.0% of the patients received at least one course of oral corticosteroid burst treatment. Asthma was well controlled in 43.1% of the patients, partly controlled in 34.9%, and uncontrolled in 22.0%. Patients reported a mean of 1.1 severe asthma exacerbations, with 49.1% experiencing 1 or more severe exacerbations. CONCLUSIONS: Overprescription and OTC purchases of SABAs are common in Brazil, possibly leading to the need for courses of oral corticosteroids. The health care community should collaborate to implement evidence-based recommendations and promote health education to improve asthma management in Brazil.

Historically, all efforts against tuberculosis were focused on rapid diagnosis and effective treatment to break the chain of transmission of Mycobacterium tuberculosis. However, in the last few years, more and more evidence has been found on the dramatic consequences of the condition defined as post-tuberculosis lung disease (PTLD). Approximately one third of patients surviving pulmonary tuberculosis face considerable ongoing morbidities, including respiratory impairment, psychosocial challenges, and reduced health-related quality of life after treatment completion. Given the important global and local burden of tuberculosis, as well as the estimated burden of PTLD, the development of a consensus document by a Brazilian scientific society-Sociedade Brasileira de Pneumologia e Tisiologia (SBPT)-was considered urgent for the prevention and management of this condition in order to allocate resources to and within tuberculosis services appropriately and serve as a guide for health care professionals. A team of eleven pulmonologists and one methodologist was created by the SBPT to review the current evidence on PTLD and develop recommendations adapted to the Brazilian context. The expert panel selected the topics on the basis of current evidence and international guidelines. During the first phase, three panel members drafted the recommendations, which were divided into three sections: definition and prevalence of PTLD, assessment of PTLD, and management of PTLD. In the second phase, all panel members reviewed, discussed, and revised the recommendations until a consensus was reached. The document was formally approved by the SBPT in a special session organized during the 2023 SBPT Annual Conference.

OBJECTIVE: To describe the construction and validation of the algorithm for Criteria for inclusion; Objective of dyspnoea; Notification of patient/family/health professionals; Facial air flow; Oxygen; Relaxion and breathing; Treating causes of dyspnoea and Opioid (CONFORTO), an instrument to guide health professionals in managing dyspnoea in patients with an advance stage of the disease at the end-of-life. METHODS: The study was carried out in three stages: (1) literature review and construction of CONFORTO; (2) semantic validation; (3) application of the CONFORTO Strategy to health professionals as a test (before video lessons) and post-test (20 days after watching video lessons) methodology. The scores obtained in the pretest and post-test were compared using the Wilcoxon test. RESULTS: Seventy-four professionals from different internal medicine and intensive care units participated in the study. The CONFORTO Strategy involved eight acronym-forming items: Criteria for inclusion; Objective of dyspnoea; Notification of patient/family/health professionals; Facial air flow; Oxygen; Relaxion and breathing; Treating causes of dyspnoea and Opioid. The post-test indicated a significant increase in the score for the following items: facial air flow (p=0.016); oxygen (p=0.002); relaxation and breathing (p=0.002) and treating the causes of dyspnoea (p=0.011). The increase in score occurred after the training sessions with video lessons. CONCLUSION: The CONFORTO Strategy proved valid and reliable for managing dyspnoea in patients with an advanced stage of the disease at the end-of-life. Because the instrument is easy-to-use, it can be used by the entire health team at any assistance-providing location, and can, thus, contribute to improving dyspnoea management for these patients.
RESUMO
OBJECTIVE: To assess the prevalence of the eosinophilic and allergic phenotypes of severe asthma in Brazil, as well as to investigate the clinical characteristics of severe asthma patients in the country. METHODS: This was a cross-sectional study of adult patients diagnosed with severe asthma and managed at specialized centers in Brazil. The study was conducted in 2019. RESULTS: A total of 385 patients were included in the study. Of those, 154 had a blood eosinophil count > 300 cells/mm3 and 231 had a blood eosinophil count of ≤ 300 cells/mm3. The median age was 54.0 years, and most of the patients were female, with a BMI of 29.0 kg/m2 and a history of allergy (81.6%). The prevalence of patients with a blood eosinophil count > 300 cells/mm3 was 40.0% (95% CI: 35.1-44.9), and that of those with a blood eosinophil count > 300 cells/mm3 and a history of allergy was 31.9% (95% CI: 27.3-36.6). Age and BMI showed positive associations with a blood eosinophil count > 300 cells/mm3 (OR = 0.97, p < 0.0001; and OR = 0.96, p = 0.0233, respectively), whereas the time elapsed since the onset of asthma symptoms showed an increased association with a blood eosinophil count > 300 cells/mm3 (OR = 1.02, p = 0.0011). CONCLUSIONS: This study allowed us to characterize the population of severe asthma patients in Brazil, showing the prevalence of the eosinophilic phenotype (in 40% of the sample). Our results reveal the relevance of the eosinophilic phenotype of severe asthma at a national level, contributing to increased effectiveness in managing the disease and implementing public health strategies.

Sleep is essential for the proper functioning of all individuals. Sleep-disordered breathing can occur at any age and is a common reason for medical visits. The objective of this consensus is to update knowledge about the main causes of sleep-disordered breathing in adult and pediatric populations, with an emphasis on obstructive sleep apnea. Obstructive sleep apnea is an extremely prevalent but often underdiagnosed disease. It is often accompanied by comorbidities, notably cardiovascular, metabolic, and neurocognitive disorders, which have a significant impact on quality of life and mortality rates. Therefore, to create this consensus, the Sleep-Disordered Breathing Department of the Brazilian Thoracic Association brought together 14 experts with recognized, proven experience in sleep-disordered breathing.

The Bacillus Calmette-Guérin (BCG) vaccine, which is widely used to protect children against tuberculosis, can also improve immune response against viral infections. This unicentric, randomized-controlled clinical trial assessed the efficacy and safety of revaccination with BCG Moscow in reducing the positivity and symptoms of COVID-19 in health care workers (HCWs) during the COVID-19 pandemic. HCWs who had negative COVID-19 IgM and IgG and who dedicated at least eight hours per week in facilities that attended to individuals suspected of having COVID-19 were included in the study and were followed for 7, 15, 30, 60, and 180 days by telemedicine. The HCWs were randomly allocated to a revaccinated with BCG group, which received the BCG vaccine, or an unvaccinated group. Revaccination with BCG Moscow was found to be safe, and its efficacy ranged from 30.0% (95.0%CI -78.0 to 72.0%) to 31.0% (95.0%CI -74.0 to 74.0%). Mycobacterium bovis BCG Moscow did not induce NK cell activation at 15-20 days post-revaccination. As hypothesized, revaccination with BCG Moscow was associated with a lower incidence of COVID-19 positivity, though the results did not reach statistical significance. Further studies should be carried out to assess whether revaccination with BCG is able to protect HCWs against COVID-19. The protocol of this clinical trial was registered on August 5th, 2020, at REBEC (Registro Brasileiro de Ensaios Clínicos, RBR-4kjqtg - ensaiosclinicos.gov.br/rg/RBR-4kjqtg/1) and the WHO (# U1111-1256-3892). The clinical trial protocol was approved by the Comissão Nacional de ética de pesquisa- CONEP (CAAE 31783720.0.0000.5078).

Many conditions result in chronic interstitial lung disease (ILD), being classified as fibrosing ILDs, including idiopathic pulmonary fibrosis, connective tissue diseases, sarcoidosis, and fibrotic hypersensitivity pneumonitis. HRCT plays an important role in the clinical evaluation of fibrosing ILDs. Current treatment perspectives are encouraging and reinforce the need for HRCT scans of adequate technical quality for early detection of fibrosing ILD. Despite efforts in this regard, the significance and management of imaging findings of early interstitial lung abnormalities have yet to be clarified. After identification of CT findings consistent with fibrosing ILD, radiologists must be able to identify characteristic morphological patterns and, in some cases, features of specific clinical entities. In cases in which HRCT features are not sufficiently specific for a definitive diagnosis, HRCT can aid in selecting the best site for surgical lung biopsy. CT follow-up is useful for identifying progressive fibrosing ILDs and detecting complications unrelated to the underlying disease, including infections, acute exacerbations, and neoplasms. Automated quantification tools have clinical applicability and are likely to be available for use in imaging analysis in the near future. In addition, incorporation of CT evaluation into scoring systems based on clinical and functional parameters for staging fibrosing disease is likely to become valuable in determining prognosis. Knowledge of the clinical applications of CT evaluation is essential for specialists managing patients with fibrosing ILD and can have a positive impact on the clinical course of the disease.

Purpose: This study aims to define which of the right ventricular myocardial deformation indices best correlates with the classic echocardiographic measurements and indices of right ventricular (RV) dysfunction in patients with stable chronic obstructive pulmonary disease (COPD). Patients and Methods: Ninety-one patients with stable COPD underwent clinical evaluation, spirometry, a 6-minute walk test, and echocardiographic examination. Patients were divided into two groups: "with RV dysfunction" (≥1 classic parameter) and "without RV dysfunction". We used speckle tracking to estimate myocardial deformation. For all analyses, results were considered significant if p < 0.05. Results: The mean age across all participants was 65 ± 9 years, with 53% (48/91) being male. Patients in the group with RV dysfunction were able to walk shorter distances and had higher estimated right ventricular systolic pressure (RVSP) and mean pulmonary arterial pressure (mPAP). The RV free wall longitudinal strain (RVFWLS) was the only deformation indices that showed a significant correlation with all classic measurements and indices in the diagnosis of RV dysfunction (Wald test, 10.24; p < 0.01; odds ratio, 1.61). In the ROC curve analysis, the absolute value <20% was the lowest cut-off point of this index for detection of RV dysfunction (AUC = 0.93, S: 95.8%, and E: 88%). Conclusion: In COPD patients, RVFWLS is the myocardial deformation index that best correlates with classic echocardiographic parameters for the diagnosis of RV dysfunction using <20% as a cut-off point.

Advances in the understanding that severe asthma is a complex and heterogeneous disease and in the knowledge of the pathophysiology of asthma, with the identification of different phenotypes and endotypes, have allowed new approaches for the diagnosis and characterization of the disease and have resulted in relevant changes in pharmacological management. In this context, the definition of severe asthma has been established, being differentiated from difficult-to-control asthma. These recommendations address this topic and review advances in phenotyping, use of biomarkers, and new treatments for severe asthma. Emphasis is given to topics regarding personalized management of the patient and selection of biologicals, as well as the importance of evaluating the response to treatment. These recommendations apply to adults and children with severe asthma and are targeted at physicians involved in asthma treatment. A panel of 17 Brazilian pulmonologists was invited to review recent evidence on the diagnosis and management of severe asthma, adapting it to the Brazilian reality. Each of the experts was responsible for reviewing a topic or question relevant to the topic. In a second phase, four experts discussed and structured the texts produced, and, in the last phase, all experts reviewed and approved the present manuscript and its recommendations.

OBJECTIVE: To determine the prevalence of incidental findings on magnetic resonance imaging (MRI) scans of the cervical, thoracic and lumbar spine in a paediatric population. MATERIALS AND METHODS: We evaluated 190 spinal MRI examinations of patients aged ≤ 18 years of age. The study included only patients for whom complete medical records were available and who underwent complete MRI examination of the cervical, thoracic or lumbar spine, including whole-spine sagittal T2-weighted sequences. Imaging findings not related to the symptom or indication for MRI were considered incidental findings. RESULTS: Of the 190 MRI examinations evaluated, 110 were in women and 80 were in men. The mean age of the study population was 12.46 ± 3.68 years. The main clinical indications for MRI in the sample were lumbago, scoliosis, dorsalgia and cervicalgia. Incidental findings were detected in the cervical, thoracic and lumbar spine in 40 (21.05%), 26 (13.83%) and 43 (22.63%) of the patients, respectively. The most common were (in the cervical spine) reversal/correction of the normal curvature; (in the thoracic spine) intravertebral disc herniation (Schmorl's node) and disc dehydration; and (in the lumbar spine) disc protrusion (12 cases), Schmorl's node (5 cases) and spondylolysis (4 cases). CONCLUSION: Incidental findings on MRI of the spine are less common in the paediatric population than in the adult population. Nevertheless, careful clinical evaluation of paediatric patients with complaints of axial and radiating pain is necessary in order to determine the correlation between symptoms and imaging findings.
OBJETIVO: Determinar a prevalência de achados incidentais em exames de ressonância magnética (RM) da coluna cervical, torácica e lombar em uma população pediátrica. MATERIAIS E MÉTODOS: Foram avaliados 190 exames de RM da coluna vertebral de pacientes com até 18 anos de idade. Foram incluídos pacientes submetidos a RM de algum segmento da coluna vertebral (cervical, torácica e lombar) com exame completo para análise (inclusive sagital T2 da coluna total) e prontuário médico devidamente preenchido. Foram considerados achados incidentais todas as alterações de imagem que não apresentavam qualquer relação com a indicação do exame ou sintoma do paciente. RESULTADOS: Dos 190 exames de RM avaliados, 110 eram de pacientes do sexo feminino e 80 de pacientes do sexo masculino. A idade média da população em estudo era de 12,46 ± 3,68 anos. As principais indicações clínicas para realização do exame de RM na amostra estudada foram lombalgia, escoliose, dorsalgia e cervicalgia. Os achados incidentais encontrados na coluna cervical, torácica e lombar foram 40 (21,05%), 26 (13,83%) e 43 (22,63%), respectivamente. Os achados incidentais mais frequentes no segmento cervical foram inversão/retificação da curvatura cervical fisiológica, no segmento torácico foram hérnia discal intrassomática (nódulo de Schmorl), seguida de desidratação discal, e no segmento lombar foram encontrados 12 exames com protrusão discal, 5 com hérnia discal intrassomática (nódulo de Schmorl) e 4 com espondilólise. CONCLUSÃO: A frequência de achados incidentais nos exames de RM da coluna vertebral na população pediátrica é menor do que na população adulta, sendo necessária avaliação clínica cuidadosa dos pacientes com queixa de dor axial e irradiada, para se estabelecer a estreita relação dos sintomas com os achados de imagem.
RESUMO
OBJECTIVE: To evaluate the disease and treatment information provided to patients with chronic obstructive pulmonary disease at hospital discharge. METHODS: This was a cross-sectional study including hospitalized patients with chronic obstructive pulmonary disease at three tertiary hospitals. The study was based on seven items of the Global Initiative for Obstructive Lung Disease (GOLD) discharge guidelines. Two hospitals in this study had a Medical Residency Program in Pulmonology, and one did not have the program. RESULTS: Fifty-four patients were evaluated. Large amounts of information were provided concerning effective pharmacological maintenance (item 1), blood gas evaluation/measurement of oxygen saturation (item 2), assessment of inhalation technique (item 4), and maintenance therapy (item 5). Less information was provided regarding comorbidity management planning (item 3), the completion of antibiotic/corticosteroid therapy (item 6) and follow-up with the attending physician or specialist (item 7) had less information. We observed significant differences between hospitals for items 1, 4 and 7, and better performance in hospitals with medical residency in pulmonology. CONCLUSION: Hospitalized patients with chronic obstructive pulmonary disease received little to no information about the seven items addressed by GOLD discharge guidelines. This finding suggests that these guidelines should be used more often by clinicians in hospital with or without medical residency in pulmonology. The lack of specialized care resulted in insufficient amount of information for patients with chronic obstructive pulmonary disease at discharge.

Rationale: Frailty in chronic obstructive pulmonary disease (COPD) patients has been associated with a higher rate of incidents, longer duration of hospitalization, poorer quality of life, and higher mortality. Objective: To measure the prevalence of frailty among COPD patients and to evaluate associated variables. Methods: A cross-sectional study. Subjects who visited a State Center for High-Cost Medicines to obtain free monthly COPD medicines were considered eligible. Individuals ≥40 years old who had a FEV1/FVC ratio of <0.7 post-bronchodilation were enrolled. The Fatigue, Resistance, Ambulation, Illnesses, and Loss of weight (FRAIL) scale, Medical Research Council dyspnea scale (MRC), COPD Assessment Test (CAT), a combination of CAT/MRC [(CAT/8)+MRC], and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) severity scale were used to evaluate the enrolled subjects. Variables associated with frailty were analyzed using an ordered logistic regression and a multivariate logistic regression. Results: The prevalence of frailty and pre-frailty among the 153 COPD subjects enrolled was 50.3% (77/153) and 35.3% (54/153), respectively. Frailty scores were correlated with CAT (correlation coefficient [cc]: 0.52, p <0.001) and MRC (cc: 0.48, p <0.001). Ordinal regression models showed that MRC and CAT were associated with fragility (p <0.0001 for both models). Higher odds of frailty were observed in GOLD groups B (p = 0.04) and D (p = 0.02). Multiple logistic regression revealed that the combination CAT/MRC≥5.5 was associated with frailty (OR 6.73; p <0.0001) and had a specificity of 80.3%, sensitivity of 62.3%, and positive and negative predictive values of 76.2% and67.8%, respectively. Conclusion: Frailty prevalence was high and was correlated with higher MRC and CAT scores. The CAT/MRC combination [(CAT/8)+MRC] ≥5.5 was highly associated with frailty, suggesting that an additional specific evaluation for the presence of frailty is indicated.

The incidence and prevalence of lung disease caused by non-tuberculous mycobacteria (NTM-LD) has increased worldwide and its diagnosis represents a complex challenge. This article aims to review the tomographic findings of NTM-LD in order to facilitate their definitive diagnosis. The search for publications on the subject was performed in PMC and Scielo using the keywords 'non-tuberculous mycobacteria', 'lung disease and computed tomography (CT)' and 'radiological findings'. The radiological findings described by 18 articles on mycobacteriosis were reviewed. In addition, CT images of patients diagnosed with NTM-LD were considered to represent radiological findings. Eighteen publications were used whose main findings were pulmonary cavitation (88.9%), bronchiectasis (77.8%), and pulmonary nodules (55.6%). Despite the overlaps in imaging-related analysis of myocobacterioses with other pulmonary infections, such as tuberculosis, the predominant involvement of the middle lobe and lingula should raise suspicion for NTM-LD.

OBJECTIVE: To evaluate the performance of the No-Apnea score, a simplified screening instrument for obstructive sleep apnea (OSA), by gender. METHODS: This was a cross-sectional study including adults undergoing full polysomnography. The No-Apnea model comprises two items (neck circumference and age) with a total score of 0 to 9. The severity of OSA was categorized, on the basis of the apnea-hypopnea index, as any (≥ 5 events/h), moderate-to-severe (≥ 15 events/h), or severe (≥ 30 events/h). The performance of the No-Apnea instrument was assessed by determining the area under the (ROC) curve (AUC) and by constructing contingency tables. RESULTS: We evaluated a total of 6,606 adults (53.8% men). For categorizing the level of OSA severity, the No-Apnea score had a sensitivity of 83.9-93.0% and a specificity of 57.3-35.2%. At all OSA severity levels, the No-Apnea score exhibited higher sensitivity and lower specificity in men than in women. The No-Apnea score proved to be an appropriate screening model for patients in general or when separated by gender or severity of OSA (AUC > 0.7 for all). The discriminatory power of the No-Apnea score to predict any, moderate-to-severe, and severe OSA was similar between genders (p = 0.109, p = 0.698, and p = 0.094, respectively). CONCLUSIONS: In a sample of adults referred to the sleep laboratory, there was no significant difference between men and women in terms of the discriminatory power of the No-Apnea instrument in for screening for OSA severity.
