Studies have reported safety concerns with short-acting beta-agonists (SABAs) monotherapy. SABA overuse contributes significantly to the healthcare burden in the Philippines. Despite Global Asthma Network's years-long advocacy for equal access to essential medicines at affordable cost, the uptake of international healthcare policies is limited in most low- and middle-income countries, including the Philippines.Areas covered: We reviewed synthesis of targeted nonsystematic literature searches on prevalence of asthma and asthma-related mortality, SABA overreliance and its adverse events, alternatives to SABA, patient referral, and multidisciplinary team (MDT) approach for asthma management. We describe regional challenges and recommendations for improving asthma care through continued multisectoral collaboration.Expert opinion: Use of medications like inhaled corticosteroid-formoterol combinations may aid in reducing adverse events including severe exacerbations, hospitalizations, complications from oral corticosteroid use, and long-term treatment costs. Raising patient awareness about preventive measures, proper inhaler techniques, and medication adherence can mitigate burden of uncontrolled asthma. Improving access to asthma medications alongside developing treatment algorithms and referral pathways (including MDT) for primary care physicians will pave the way for optimal asthma care in LMICs, including the Philippines.","PeriodicalId":94007,"journal":{"name":"Expert review of respiratory medicine","volume":" ","pages":"947-962"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Validity of NMR in improving adherence to these PT?Method: We carried out an SRL (six databases) and an MA for responding to the questions.Results: PT for SC (any treatment) is more effective in smoking subjects with slow NMR compared with fast NMR. Varenicline (VR) is equally effective in fast and slow NMR (RR 1.04 [CI 95% 0.75, 1.44]). When we compared those smokers who were treated to quit smoking with VR or nicotine replacement therapy (NRT) in fast metabolizers, we found that abstinence was in favor of those who were treated with VR (RR 1.40 [CI 95% 1.02, 1.91]). Those who were treated to quit smoking with NRT presented better results in slow Metabolizers (RR 0.70 [CI 95% 0.58, 0.83]).

Older techniques such as rigid bronchoscopy maintain an important role in central airway obstruction. Renewed interest in the peripheral pulmonary nodule is driving major advances in technologies to increase the diagnostic accuracy and advance new potential endoscopic therapeutic options.Areas covered: This paper describes the role of pulmonary endoscopy, in particular ultrasound in the diagnosis and staging of lung malignancy. We will explore the recent expansion of ultrasound to include endoscopic ultrasound - bronchoscopy (EUS-B) and combined ultrasound (CUS) techniques. We will discuss in detail the advances in the workup of the peripheral pulmonary nodule.We performed a non-systematic, narrative review of the literature to summarize the evidence regarding the indications, diagnostic yield, and safety of current bronchoscopic sampling techniques.Expert opinion: EBUS/EUS-B has revolutionized the diagnosis and staging of thoracic malignancy resulting in more accurate assessment of the mediastinum compared to mediastinoscopy alone, thus reducing the rate of futile thoracotomies. Although major advances in the assessment of the peripheral pulmonary nodule have been made, the role of endoscopy in this area requires further clarification and investigation.","PeriodicalId":94007,"journal":{"name":"Expert review of respiratory medicine","volume":" ","pages":"843-860"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142383058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern medicine offers several advancements in diagnostics and therapeutics of TB, but they often remain to be extensively implemented in real life. In high-income countries TB is now relatively uncommon, but it remains a health and socio-economic burden that should not be underestimated.Expert opinion: Pulmonologists should maintain expertise toward TB for several reasons. First, the lung is the most common and the infectious moiety of TB. Second, TB remains a global issue due to common travels of western people and migrations from areas with high incidence of TB. Third, as TB has heterogenous clinics, its prompt diagnosis may be difficult. Fourth, TB is a curable disease, but its management is complex and predisposes to poor adherence with failures/relapses and selection of drug-resistant strains.","PeriodicalId":94007,"journal":{"name":"Expert review of respiratory medicine","volume":" ","pages":"861-872"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis revealed 87 altered metabolites, suggesting changes in the metabolism of arachidonic acid, glycerolipids, glycerophospholipids, linoleic acid, pyruvate, glycolysis, among others. Most of these metabolites are involved in inflammatory, hypoxic, and thrombotic processes. At baseline, the greatest differences were found in phosphatidylcholine (PC) 31:4 (p < 0.001), phosphoserine (PS) 34:3 (p < 0.001), and phosphatidylcholine (PC) 36:5 (p < 0.001), all of which were notably decreased in COVID-19 patients.
