- Comparative Performance of Screening Instruments for Obstructive Sleep Apnea in Morbidly Obese Patients Referred to a Sleep Laboratory: a Prospective Cross-Sectional StudyPublication . Duarte, R; Mello, F; Magalhães-da-Silveira, F; Oliveira e Sá, T; Rabahi, M; Gozal, DPurpose: Obstructive sleep apnea (OSA) is very common occurrence among morbidly obese patients. Our main objectives were to validate the No-Apnea, a 2-item screening tool, in morbidly obese patients and compare its performance with three other instruments: STOP-Bang questionnaire, NoSAS score, and Epworth Sleepiness Scale (ESS). Methods: A cross-sectional analysis of morbidly obese patients (body mass index [BMI] ≥ 35.0 kg/m2) grouped into two independent samples: bariatric surgery patients (BS) and non-bariatric surgery patients (NBS). All patients underwent overnight polysomnography. Discriminatory ability was assessed by area under the curve (AUC). OSA severity was defined by apnea/hypopnea index cut-off points: ≥ 5.0/h (OSA≥5), ≥ 15.0/h (OSA≥15), and ≥ 30.0/h (OSA≥30). Results: A total of 1017 subjects (40.4% in BS cohort and 59.6% in NBS cohort) were evaluated. In the BS cohort, No-Apnea had similar discrimination to STOP-Bang and NoSAS for predicting OSA≥5 (p = 0.979 and p = 0.358, respectively), OSA≥15 (p = 0.158 and p = 0.399, respectively), and OSA≥30 (p = 0.388 and p = 0.903, respectively). In the NBS cohort, No-Apnea had similar discrimination to STOP-Bang and NoSAS for predicting OSA≥5 (p = 0.528 and p = 0.428, respectively), OSA≥15 (p = 0.825 and p = 0.108, respectively), and OSA≥30 (p = 0.458 and p = 0.186, respectively). Moreover, No-Apnea performed significantly better than ESS in both BS and NBS cohorts (p < 0.001). Conclusions: No-Apnea is a useful and practical tool for screening of OSA in morbidly obese patients, with non-inferior performance to STOP-Bang questionnaire and NoSAS score.
- Erasmus Syndrome: an Underrecognized EntityPublication . Magalhães, A; Moreira, I; Pinheiro, S; Borba, AWe present a case of a 33-year-old male who worked as a plumber and a locksmith. The patient presented with diffuse myalgia and asthenia, skin sclerosis and puffy fingers, Raynaud's phenomenon, exertional dyspnea and erectile dysfunction. The presence of specific autoantibodies enabled the diagnosis of systemic sclerosis. Chest-computed tomography revealed upper lobe consolidation. After extensive evaluation, the multidisciplinary interstitial lung disease team concluded that the patient also had advanced silicosis. After a year, there was significant clinical, radiologic, and functional deterioration of the lung disease. The patient was referred for lung transplant. Silica inhalation is the cause of silicosis but is also implicated in the development of systemic sclerosis (Erasmus syndrome). Although they share a common risk factor, it is rare to find both diseases co-existing. We present this case of a young patient where both diseases presented aggressively in order to raise awareness to this association.
- Patient-Physician Discordance in Assessment of Adherence to Inhaled Controller Medication: a Cross-Sectional Analysis of Two CohortsPublication . Jácome, C; Pereira, AM; Almeida, R; Ferreira-Magalhaes, M; Couto, M; Araujo, L; Pereira, M; Alves Correia, M; Chaves Loureiro, C; Catarata, MJ; Maia Santos, L; Pereira, J; Ramos, B; Lopes, C; Mendes, A; Cidrais Rodrigues, JC; Oliveira, G; Aguiar, AP; Afonso, I; Carvalho, J; Arrobas, A; Coutinho Costa, J; Dias, J; Todo Bom, A; Azevedo, J; Ribeiro, C; Alves, M; Leiria Pinto, P; Neuparth, N; Palhinha, A; Gaspar Marques, J; Pinto, N; Martins, P; Todo Bom, F; Alvarenga Santos, M; Gomes Costa, A; Silva Neto, A; Santalha, M; Lozoya, C; Santos, N; Silva, D; Vasconcelos, MJ; Taborda-Barata, L; Carvalhal, C; Teixeira, MF; Rodrigues Alves, R; Moreira, AS; Sofia Pinto, C; Morais Silva, P; Alves, C; Câmara, R; Coelho, D; Bordalo, D; Fernandes, R; Ferreira, R; Menezes, F; Gomes, R; Calix, MJ; Marques, A; Cardoso, J; Emiliano, M; Gerardo, R; Nunes, C; Câmara, R; Ferreira, JA; Carvalho, A; Freitas, P; Correia, R; Fonseca, JOBJECTIVE: We aimed to compare patient's and physician's ratings of inhaled medication adherence and to identify predictors of patient-physician discordance. DESIGN: Baseline data from two prospective multicentre observational studies. SETTING: 29 allergy, pulmonology and paediatric secondary care outpatient clinics in Portugal. PARTICIPANTS: 395 patients (≥13 years old) with persistent asthma. MEASURES: Data on demographics, patient-physician relationship, upper airway control, asthma control, asthma treatment, forced expiratory volume in one second (FEV1) and healthcare use were collected. Patients and physicians independently assessed adherence to inhaled controller medication during the previous week using a 100 mm Visual Analogue Scale (VAS). Discordance was defined as classification in distinct VAS categories (low 0-50; medium 51-80; high 81-100) or as an absolute difference in VAS scores ≥10 mm. Correlation between patients' and physicians' VAS scores/categories was explored. A multinomial logistic regression identified the predictors of physician overestimation and underestimation. RESULTS: High inhaler adherence was reported both by patients (median (percentile 25 to percentile 75) 85 (65-95) mm; 53% VAS>80) and by physicians (84 (68-95) mm; 53% VAS>80). Correlation between patient and physician VAS scores was moderate (rs=0.580; p<0.001). Discordance occurred in 56% of cases: in 28% physicians overestimated adherence and in 27% underestimated. Low adherence as assessed by the physician (OR=27.35 (9.85 to 75.95)), FEV1 ≥80% (OR=2.59 (1.08 to 6.20)) and a first appointment (OR=5.63 (1.24 to 25.56)) were predictors of underestimation. An uncontrolled asthma (OR=2.33 (1.25 to 4.34)), uncontrolled upper airway disease (OR=2.86 (1.35 to 6.04)) and prescription of short-acting beta-agonists alone (OR=3.05 (1.15 to 8.08)) were associated with overestimation. Medium adherence as assessed by the physician was significantly associated with higher risk of discordance, both for overestimation and underestimation of adherence (OR=14.50 (6.04 to 34.81); OR=2.21 (1.07 to 4.58)), while having a written action plan decreased the likelihood of discordance (OR=0.25 (0.12 to 0.52); OR=0.41 (0.22 to 0.78)) (R2=44%). CONCLUSION: Although both patients and physicians report high inhaler adherence, discordance occurred in half of cases. Implementation of objective adherence measures and effective communication are needed to improve patient-physician agreement.
- Perception of Sleep Duration in Adult Patients with Suspected Obstructive Sleep ApneaPublication . Duarte, R; Mendes, B; Oliveira-e-Sá, T; Magalhães-da-Silveira, F; Gozal, DPurpose: Discrepancies between subjective and objective measures of total sleep time (TST) are frequent among insomnia patients, but this issue remains scarcely investigated in obstructive sleep apnea (OSA). We aimed to evaluate if sleep perception is affected by the severity of OSA. Methods: We performed a 3-month cross-sectional study of Brazilian adults undergoing overnight polysomnography (PSG). TST was objectively assessed from PSG and by a self-reported questionnaire (subjective measurement). Sleep perception index (SPI) was defined by the ratio of subjective and objective values. Diagnosis of OSA was based on an apnea/hypopnea index (AHI) ≥ 5.0/h, being its severity classified according to AHI thresholds: 5.0-14.9/h (mild OSA), 15.0-29.9/h (moderate OSA), and ≥ 30.0/h (severe OSA). Results: Overall, 727 patients were included (58.0% males). A significant difference was found in SPI between non-OSA and OSA groups (p = 0.014). Mean SPI values significantly decreased as the OSA severity increased: without OSA (100.1 ± 40.9%), mild OSA (95.1 ± 24.6%), moderate OSA (93.5 ± 25.2%), and severe OSA (90.6 ± 28.2%), p = 0.036. Using logistic regression, increasing SPI was associated with a reduction in the likelihood of presenting any OSA (p = 0.018), moderate/severe OSA (p = 0.019), and severe OSA (p = 0.028). However, insomnia was not considered as an independent variable for the presence of any OSA, moderate/severe OSA, and severe OSA (all p-values > 0.05). Conclusion: In a clinical referral cohort, SPI significantly decreases with increasing OSA severity, but is not modified by the presence of insomnia symptoms.
