Currently, the go-to clinical measure that determines the presence and severity of OSA is the apnea-hypopnea index (AHI). The AHI captures the frequency of respiratory events due to changes in ventilation that are associated with either oxygen desaturations or arousal from sleep. The AHI is poorly correlated to adverse outcomes in OSA with poor prognostic ability. To overcome the limitations of AHI and perhaps driven by the ease of acquisition, several studies have suggested characterizing nocturnal hypoxia in OSA, termed as \"hypoxic burden\". The purpose of this review is to focus on the hypoxic burden in OSA, its various definitions, and its utility in moving OSA diagnosis beyond the AHI.Recent findings: Several measures and definitions of hypoxic burden have been proposed and studied that show promise in overcoming limitations of AHI and also have a greater prognostic ability than AHI. More recently, area-based measures that attempt to characterize the depth and duration of oxygen desaturations, i.e., nocturnal hypoxia in OSA, have been shown to better relate to incident cardiovascular disease than AHI. In this review, we delve into the evidence for these novel area-based metrics and also delve into the pathophysiological concepts underlying nocturnal hypoxia while cautioning the reader on interpretation of the recent findings relating hypoxic burden to adverse outcomes in OSA.Summary: In this review on hypoxic burden, we focus on the need that has driven the sudden influx of studies assessing hypoxic burden for various outcomes of OSA, its underlying pathophysiology, the various definitions, and clinical relevance. We hope that the reader can appreciate the nuances underlying hypoxic burden in OSA and suggest the need for a cohesive framework for moving beyond the AHI with hypoxic burden.","PeriodicalId":11090,"journal":{"name":"Current Opinion in Pulmonary Medicine","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142125109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinicians need to be aware of the various palliative interventions in order to implement guidelines' recommendations. This review provides an update on evidence-based palliative therapies.Recent findings: Literature review indicates early integration of palliative care in pulmonary fibrosis is feasible and meets patient needs. Key components of a primary palliative approach include comprehensive symptoms and needs screening, systematic symptom management using nonpharmacologic interventions, supplemental oxygen and opioids for dyspnea and cough. Patient-centered communication is essential for successful integration of palliative care. Early, iterative advance care planning in clinic to understand patient goals, values and preferences for current and future care, improves patient care and satisfaction. Prioritizing caregiver inclusion in clinics can address their needs. Collaborating with a multidisciplinary allied team facilitates integration of palliative care and supports patients throughout the disease course. Different models of palliative care delivery exist and can be adapted for local use. The use of artificial intelligence algorithms and tools may improve care and continuity.Summary: Clinicians must develop competency in palliative care.

These symptoms not only indicate autoimmune diseases but also hint at potential genetic disorders, suggesting a potential overlap between genetic and autoimmune origins.Recent findings: Genetic factors contributing to ILD are predominantly associated with telomere (TRG) and surfactant-related genes. While surfactant-related gene mutations typically manifest with pulmonary involvement alone, TRG mutations were initially linked to syndromic forms of pulmonary fibrosis, known as telomeropathies, which may involve hematological and hepatic manifestations with variable penetrance. Recognizing extra-pulmonary signs indicative of telomeropathy should prompt the analysis of TRG mutations, the most common genetic cause of familial pulmonary fibrosis. Additionally, various genetic diseases causing ILD, such as alveolar proteinosis, alveolar hemorrhage, or unclassifiable pulmonary fibrosis, often present as part of syndromes that include hepatic, hematological, or skin disorders.Summary: This review explores the main genetic conditions identified over the past two decades.","PeriodicalId":11090,"journal":{"name":"Current Opinion in Pulmonary Medicine","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141418214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So far, transcatheter edge-to-edge repair is most frequently used with procedural success rates of more than 95% and improvements in functional and quality of life parameters for up to 2 years. Right ventricular function as well as pulmonary artery pressure and resistance levels are important outcome predictors.

Improvements in symptoms and quality of life can persist longer term, whereas functional capacity does not; therefore, strategies to preserve functional capacity are an important area of research. Referral early in the disease course is encouraged to promote longer lasting effects. Evidence that high-intensity interval training may optimize benefits of exercise training is emerging. Supplemental oxygen is frequently used to manage exercise-induced desaturation, although its use as an adjunct therapy requires more evidence.Summary: Current evidence strongly supports the inclusion of pulmonary rehabilitation in the standard holistic care of IPF, with early participation encouraged.

The application of cluster analysis to organize sarcoidosis patients into developmental phenotypes is underway.

It is mirrored by progressive pulmonary fibrosis (PPF), an umbrella term which characterizes disease behavior of various fibrotic interstitial lung diseases with irreversible progression, accounting for loss of lung function, exercise intolerance and respiratory failure leading to early mortality. Pirfenidone and nintedanib halve the decline in lung function but do not halt disease progression.Recent findings: Since the publication in 2014 of pivotal pirfenidone and nintedanib studies, a number of clinical trials were conducted, many of them did not reach their primary endpoints. In IPF, promising phase 2 trials were followed by large phase 3 trials that did not confirm a favorable efficacy to tolerability favorable profile, including those with ziritaxestat, an autotaxin-1 inhibitor, zinpentraxin-alpha (human recombinant pentraxin-2), and the monoclonal antibody pamrevlumab targeting connective tissue growth factor.

Accordingly, exPH is defined as a mean pulmonary arterial pressure (mPAP)/cardiac output ( CO ) slope greater than 3 mmHg/l/min. Key considerations for this re-introduction included increasing understanding on normal pulmonary hemodynamics during exercise and the broadly available evidence on the association of an abnormal mPAP/ CO slope with poor survival in the general population and in different disease entities.Summary: Exercise (patho-)physiology has opened a new field for clinical research facilitating recognition of cardiovascular and pulmonary vascular diseases in an early stage.
