This article provides an updated review on pulmonary COVID-19, while highlighting the key imaging features that can identify and distinguish acute COVID-19 pneumonia and its chronic sequelae from other diseases.Recent findings: Acute COVID-19 pneumonia typically presents with manifestations of organizing pneumonia on computed tomography (CT). In cases of severe disease, patients clinically progress to acute respiratory distress syndrome, which manifests as diffuse alveolar damage on CT. The most common chronic imaging finding is ground-glass opacities, which commonly resolves, as well as subpleural bands and reticulation. Pulmonary fibrosis is an overall rare complication of COVID-19, with characteristic features, including architectural distortion, and traction bronchiectasis.Summary: Chest CT can be a helpful adjunct tool in both diagnosing and managing acute COVID-19 pneumonia and its chronic sequelae. It can identify high-risk cases and guide decision-making, particularly in cases of severe or complicated disease. Follow-up imaging can detect persistent lung abnormalities associated with long COVID and guide appropriate management.","PeriodicalId":11090,"journal":{"name":"Current Opinion in Pulmonary Medicine","volume":" ","pages":"183-195"},"PeriodicalIF":2.8,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143122389","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}

Their introduction has offered hope for patients and prescribers with a growing list of novel medications and indications. While 'step-up' indications for biologic initiation are well described in guidelines, 'step-down' strategy remains poorly understood and thus guidance is limited. In this opinion article we aim to focus on recent practice changing evidence for stepping-down severe asthma management, tools for the assessment of biologic efficacy, propose a framework for the step-down of biologic and nonbiologic therapies and suggest topics of interest for future research.Recent findings: Clinical tools have been developed to aid in assessing biologic response. Some patients experience marked improvement and may enter a period of clinical remission or even complete remission. Following positive response, add-on therapy may safely be approached for taper or withdrawal.Summary: There is limited consensus but growing evidence for stepping-down therapies in patients who achieve clinical response and/or remission after biologic initiation. Further structured guidance would benefit clinicians who face clinical uncertainty when deciding to step-down therapy in patients with well controlled asthma.","PeriodicalId":11090,"journal":{"name":"Current Opinion in Pulmonary Medicine","volume":" ","pages":"294-301"},"PeriodicalIF":2.8,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522924","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}

Asthma is an umbrella term that defines a complex group of heterogenous airway disorders, which are broadly categorized into predominantly T2 or non-T2 phenotypes depending on the presence and levels of airway and systemic biomarkers associated with a T2 inflammatory response. Individuals with predominant T2 asthma have greater numbers of peripheral blood eosinophils, exhaled nitric oxide and IgE. These patients have more atopy and earlier onset asthma. In contrast, the absence or low levels of these biomarkers define non-T2 asthma. This is a heterogenous group with a later onset of asthma that is also more commonly associated with obesity and with females.Recent findings: This article summarizes new information regarding the plasticity that exists between T2 and non-T2 mechanisms, including their role in exacerbation-prone and nonexacerbating asthma, and many of the risk factors associated with the non-T2 phenotype, such as viral infections, ambient air pollution exposure, smoking, genetic and metabolic factors. It also provides new information on the immunological and metabolic mechanisms associated with non-T2 asthma. We also discuss how to manage this asthma phenotype and how treatment responses differ for these patients.Summary: Non-T2 asthma defines a heterogenous group of asthma phenotypes. However, acknowledging that the absence of T2 biomarkers is influenced by several factors is important and can longitudinally change in relation to exacerbations, particularly in children.","PeriodicalId":11090,"journal":{"name":"Current Opinion in Pulmonary Medicine","volume":" ","pages":"287-293"},"PeriodicalIF":2.8,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11949703/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143691229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This narrative review aims to provide an overview of the existing international and national guidelines on the IPC measures to control epidemic and pandemic-prone ARIs in healthcare settings.Recent findings: The WHO has recently produced a report proposing an updated terminology for respiratory pathogens. One of the key outcomes of this consultation was the adoption of the term 'infectious respiratory particles' (IRPs). According to the report, IRPs are defined as infectious particles that can be expired from an infected person through activities like breathing, talking, singing, coughing, sneezing, or even spitting. Most notably, there is no longer the clear and traditional distinction between droplet and aerosol based on the cut-off of particle size, but rather a continuum of particle sizes of IRPs.Summary: Among other recommendations, all international guidelines place emphasis on the use of standard and transmission-based precautions when dealing with respiratory viruses. It is important to assess how the new proposed terminology for respiratory pathogens may affect the current existing IPC measures.","PeriodicalId":11090,"journal":{"name":"Current Opinion in Pulmonary Medicine","volume":" ","pages":"230-236"},"PeriodicalIF":2.8,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143515013","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}

The importance of airway remodelling and infection in the pathophysiology of preschool wheeze is increasingly appreciated. The treatment of preschool wheeze is moving from symptom-based to biomarker driven therapies. Other important areas are prediction of risk of asthma attacks, the SMART regime, the importance of climate change and reducing greenhouse gas emissions from inhalers while ensuring adequate therapy for young children, the association of early adverse environmental factors including childhood poverty and deprivation and the switch to race-neutral lung function equations.Summary: We are increasingly moving towards personalized medicine and the use of biomarkers to guide treatment of wheeze at all ages, but we need to move from counting cells to determining their functional status.

We highlight evidence of occupational exposures and how they relate to COPD, while also looking at gaps in how the changing workplace might affect the occupational COPD landscape.Recent findings: Historical exposures linked to COPD included inorganic dusts like coal and silica and organic dusts like cotton and wood. Other data associated agricultural exposures, cleaning agents, air pollution, and construction work with COPD. As the workplace has evolved to include more work from home and growing industries like ridesharing and delivery, items like radon and indoor and outdoor air quality must be factored into the equation as occupational exposures with the potential to cause COPD and increase its morbidity. Despite this, causal conclusions with many risk factors are challenging due to the complex interaction between patient susceptibilities and environmental factors, both occupation-related and nonoccupation related.Summary: Additional studies are needed, not only to better evaluate occupational exposures and COPD pathogenesis, but also to look at more solution-oriented areas like precision medicine and interventions targeting a healthier workplace.","PeriodicalId":11090,"journal":{"name":"Current Opinion in Pulmonary Medicine","volume":" ","pages":"98-105"},"PeriodicalIF":2.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142675410","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}

Improvement in treatment strategies is pendant further understand of their underpinnings across the spectrum of disease severity.Recent findings: Emerging literature has been reviewed based on a conceptual framework that relates ventilatory demand to capacity under the modulating influence of sub-cortical and cortical centers (symptom perception and affective interpretation). Evidence supporting these fundamental tenets is critically appraised, focusing on mechanistic and interventional studies that shed novel light on the sources of heightened and/or mechanically constrained ventilation. Mechanistic studies using proxies of the inspiratory neural drive (e.g., diaphragm electromyography) were particularly informative, as well as interventional trials aimed at decreasing afferent stimulation and/or symptom perception via pharmacological (e.g., low-dose opiates in selected patients, high flow oxygen, oral nitrate) and nonpharmacological (e.g., novel exercise training paradigms, inspiratory muscle training, breathing techniques) interventions.Summary: Therapeutic and rehabilitative strategies to lessen dyspnea's devastating impact on quality of life should minimize demand in the setting of reduced capacity and increased sensation awareness in COPD.

As emerging evidence continues to show substantial benefits in reducing mortality and hospitalizations, it's crucial to identify which patients will benefit most and to provide clear guidance on implementing homeNIV effectively.Recent findings: Recent research supports the use of high intensity homeNIV for CHRF secondary to COPD, showing marked reductions in hospitalizations and mortality. However, despite its proven benefits, homeNIV is underutilized, often due to significant barriers related to payor policies and gaps in knowledge by those most likely to be evaluating and managing patients with advanced COPD. The literature also reveals ongoing debate about the optimal timing and setting for starting homeNIV, whether in outpatient clinics or directly after hospital discharge.Summary: The evidence suggests that homeNIV should be more widely used, with a focus on early initiation and careful titration to normalize PaCO 2 over time. By addressing the barriers to its broader use, we can improve outcomes for patients with CHRF due to COPD.","PeriodicalId":11090,"journal":{"name":"Current Opinion in Pulmonary Medicine","volume":" ","pages":"165-174"},"PeriodicalIF":2.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142853276","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}
