We aimed to assess the accuracy of the heart rate characteristics index (HRCi) to assess the dynamic risk of mortality among infants managed with low and high target SpO2ranges.The SUPPORT and HRCi datasets from one center where both RCTs overlapped were linked. We examined the maximum daily HRCi (MaxHRCi24) to predict death among patients randomized to the lower and higher SpO2groups by generating predictiveness curves and calculating model performance metrics, including AUROC at prediction windows from 1–60 days. Cox proportional hazards models tested whether MaxHRCi24 was an independent predictor of death. We also conducted a moderation analysis.There were 84 infants in the merged dataset. MaxHRCi24 predicted death in subjects randomized to lower target SpO2, with area under the receiver operating characteristic curve (AUROCs 0.79–0.89) depending upon the prediction window, and higher target SpO2(AUROCs 0.82–0.91). MaxHRCi24 was an important additional predictor of death in multivariable modeling. In moderation analysis, in a model that also included demographic predictor variables, the individual terms and the interaction term between MaxHRCi24 and target SpO2range all predicted death.Associations between HRCi and mortality, at low and high SpO2target ranges, suggest that future research may find HRCi metrics helpful to individually optimize target oxygen saturation ranges for hospitalized preterm infants.","PeriodicalId":504874,"journal":{"name":"ERJ Open Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140244383","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}

CHRF is the major cause of morbidity and mortality, necessitating early diagnosis and intervention. Guidelines suggest an arterial blood gas (ABG) is indicated if oxygen saturations (SpO2)≤94% in the absence of lung disease. However, hypercapnia with normoxia (SpO2≥95%) has been observed on ABGs of patients with NMD, in particular those with motor neurone disease (MND).A single-centre retrospective audit of room-air ABGs in stable hypercapnic chronic respiratory failure (CHRF) patients from 1990–2020 was performed. Patients with parenchymal lung disease were excluded. Patients were grouped into three main categories: non-NMD, other-NMD and MND.Two-hundred and ninety-seven ABGs with hypercapnia from 180 patients with extrinsic restrictive lung disease were analysed. No patients with non-NMD, 54% of other-NMD and 36% of MND patients demonstrated hypercapnia with normoxia (χ261.33; p<0.001). The potential mechanism is proposed to be a difference in calculated respiratory quotient (RQ). If the A-a gradient is assumed to be normal, the calculated RQ was significantly higher in MND patients and other-NMD patients compared with non-NMD patients (estimated-marginal-mean 0.99 [95%CI 0.94–1.03]; 0·86 [95%CI 0.76–0.96]; 0·73 [95%CI 0.63—0.83] respectively; p<0.001) by mixed-model analysis.Hypercapnia is not excluded with normal oximetry in NMD patients and may be due to an elevated RQ. This has implications in the diagnosis and monitoring of respiratory insufficiency in NMD patients with oximetry alone.Dr Emma Gray received an NHMRC Postgraduate Scholarship.","PeriodicalId":504874,"journal":{"name":"ERJ Open Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140258610","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}

In light of the obesity epidemic, it is important to understand how body composition affects interpretation of CPET results.to assess the relationship between CPET measures, others than peak oxygen uptake, and body composition.A total of 330 participants, aged 50 years, performed both a CPET and a Dual-energy x-ray absorptiometry (DXA). From CPET, peak exercise respiratory exchange ratio (RER), ventilatory efficiency (VE/VCO2slope) and work efficiency (ΔVO2/ΔWR) were recorded. Pearson's correlation was used to assess the association between CPET measures and selected body composition measures including body mass index (BMI), waist circumference, fat mass, lean mass, body fat percentage and percentage trunk fat to fat mass. All analyses were done stratified by sex. A p-value<0.05 defined statistical significance.RER was negatively correlated with body composition measures; the strongest correlation was observed with waist circumference in females (r=−0.36). VE/VCO2slope had no significant correlations with any body composition measures.ΔVO2/ΔWR was positively correlated with the body composition measures; the strongest correlation was observed with BMI (r=0.24). The additive role of percentage body fat and percentage trunk fat were studied in a linear regression model using waist circumference and BMI to predict the above-named CPET measures and no additive role was found.RER andΔVO2/ΔWR may be influenced by body composition while VE/VCO2slope is not affected.

COPD patients at increased mortality risk are those that are more symptomatic, have lower lung function and lower DLCO, have decreased exercise capacity, belong to the emphysematous phenotype and those who have concomitant bronchiectasis. Also mortality risk seems to be greater in patients who experience COPD exacerbations and in those who suffer from concomitant cardiovascular and/or metabolic diseases. To predict the risk of death in COPD patients several composite scores have been created using different parameters. In the previous years, large studies (also called Mega-Trials) have evaluated the efficacy of different therapies on COPD mortality, but until recently only non-pharmaceutical interventions have proven to be effective. However, recent studies on fixed combinations of triple therapy (long-acting beta agonists, long-acting muscarinic antagonists and inhaled corticosteroids) have provided encouraging results, showing for the first time a reduction in mortality compared to dual therapies. The aim of the present review is to summarize available data regarding mortality risk in COPD patients and to describe pharmacologic therapies that have shown effectiveness in reducing mortality.","PeriodicalId":504874,"journal":{"name":"ERJ Open Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140260274","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}

Data was collected through a one-time face-to-face semi-structured interview. The interviews were transcribed and independently analysed by two researchers using thematic analyses.Twelve patients and four significant others (56% female; age: 63±11 years) have been interviewed. Participants expressed a variety of information needs and learning preferences. Subthemes that emerged within the theme of motivation for learning were: 1) curiosity, such as knowledge gaps and hope for new information; and 2) values and goals, such as own health, caring for loved ones and spending time with family.To enhance intrinsic motivation for learning within PR, autonomy of individuals should be supported by offering several learning topics and education adapted to preferences, while curiosity should be fostered by targeting information needs. Moreover, health education programs should match with the personal values and goals of individuals, such as own health, caring for loved ones and spending time with family.","PeriodicalId":504874,"journal":{"name":"ERJ Open Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140077290","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}
