Obstructive sleep apnea (OSA) is a heterogeneous disorder. If left untreated, OSA has major health, safety and economic consequences. In addition to varying levels of impairment in pharyngeal anatomy (narrow/collapsible airway), non-anatomical ‘phenotypic traits’ are also important contributors to OSA for most patients. However, the majority of existing therapies only target the anatomical cause (e.g. continuous positive airway pressure [CPAP], oral appliances, weight loss, positional therapy, and upper airway surgery). These are typically administered as monotherapy according to a trial and error management approach in which the majority of patients are first prescribed CPAP. Despite its high effectiveness, CPAP adherence remains unacceptably low and second-line therapies have variable and unpredictable efficacies. Recent advances in knowledge of the multiple causes of OSA using respiratory phenotyping techniques have identified new targets or ‘treatable traits’ to direct therapy. Identification of the traits and development of therapies that selectively target one or more of the treatable traits has the potential to personalize the management of this chronic health condition to optimize patient outcomes according to precision medicine principles.
Patients with high eosinophilic levels have a good response to biologics. Nasal polyps are associated with allergic asthma. In these patients, anti-immunoglobulin (Ig) E and anti-interleukin (IL)-5 have proven efficacy. In the Global Initiative for Asthma (GINA) guidelines, the severity of symptoms is one of the major criteria in choosing a treatment. ICS are prescribed at the initial steps of asthma management, but analysis of comorbidities helps to adapt the treatment
Postoperative Pulmonary Complications Br J Anaesth. 2017;118(3):317-334. Changes to the respiratory system occur immediately on induction of general anaesthesia: respiratory drive and muscle function are altered, lung volumes reduced, and atelectasis develops in > 75% of patients receiving a neuromuscular blocking drug..The respiratory system may take 6 weeks to return to its preoperative state after general anaesthesia for major surgery. clinicians should be aware of non-modifiable and modifiable factors in order to recognize those at risk and optimize their care.Preventative measures include preoperative optimization of co-morbidities, smoking cessation, and correction of anaemia, in addition to intraoperative protective ventilation strategies and appropriate management of neuromuscular blocking drugs. Protective ventilation includes low tidal volumes, which must be calculated according to the patient's ideal body weight. the most beneficial level of PEEP is required,
2000 classification of idiopathic interstitial lung diseases The 2000 classification consists of seven entities of idiopathic interstitial diseases which are defined on clinical, radiological and pathological criteria: idiopathic pulmonary fibrosis, non-specific interstitial pneumonia, cryptogenic organizing pneumonia, acute interstitial pneumonia, respiratory bronchiolitis associated interstitial lung disease, desquamative interstitial pneumonia and lymphoid interstitial pneumonia. The most frequent is Idiopathic Pulmonary Fibrosis, which has a poor prognosis.
Risk factors for lung cancer worldwide Tobacco smoking is the major determinant of lung cancer risk; genetics, occupation, pollution, poor diet also contribute.
