Abstract
Chronic obstructive pulmonary disease (COPD) is preventable and requires early screening. The study aimed to examine the clinical values of long non-coding RNA (lncRNA) SNHG5 in COPD diagnosis and prognosis. Out of 160 COPD patients, 80 were in the stable stage and 80 were in the acute exacerbation of COPD stage (AECOPD). SNHG5 expression was detected via qRT-PCR. The survival analysis was conducted using Cox regression analysis and K-M curve. SNHG5 levels significantly reduced in both stable COPD and AECOPD groups compared with the control group, with AECOPD group recording the lowest values. SNHG5 levels were negatively correlated with GOLD stage. Serum SNHG5 can differentiate stable COPD patients from healthy individuals (AUC = 0.805), and can screen AECOPD from stable ones (AUC = 0.910). SNHG5 negatively influenced the release of inflammatory cytokines. For AECOPD patients, those with severe cough and wheezing dyspnea symptoms exhibited the lowest values of SNUG5. Among the 80 AECOPD patients, 16 cases died in the one-year follow-up, all of whom had low levels of SNHG5. SNHG5 levels independently influenced survival outcomes, patients with low SNHG5 levels had a poor prognosis. Thus, lncRNA SNHG5, which is downregulated in patients with COPD (especially AECOPD), can potentially protect against AECOPD and serve as a novel prognostic biomarker for AECOPD.

Abstract
OBJECTIVE To evaluate the efficacy of high-flow nasal oxygen therapy (HFNO) vs. non-invasive positive pressure ventilation (NIPPV) in type II respiratory failure, and analyze their impact on blood gas parameters. METHODS A retrospective analysis of 110 cases of type II respiratory failure treated from April 2021 to March 2023 categorized patients into control (NIPPV, n=50) and observation (HFNO, n=60) groups. Both groups received comprehensive nursing interventions. Treatment outcomes, respiratory and hemodynamic parameters, blood gas parameters, and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were compared before and 48 hours after treatment. Additionally, the complication rates and independent risk factors affecting prognosis were analyzed. RESULTS The observation group exhibited superior treatment efficacy compared to the control group (P=0.001). Both groups showed significant improvements in APACHE II scores and respiratory, hemodynamic, and blood gas parameters after treatment (P<0.001), with the observation group experiencing more pronounced improvements (P<0.001). The observation group also had a lower incidence of complications than the control group (P=0.013). Logistic regression identified PaCO2 and treatment protocol as independent risk factors affecting adverse outcomes (P<0.05). CONCLUSION HFNO demonstrates superior therapeutic efficacy in type II respiratory failure, significantly improving blood gas parameters with a high level of safety, supporting its clinical applicability.

Abstract
Objective To explore the clinical effect of budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler (BGF MDI) combined with high-flow nasal cannula (HFNC) in the treatment of elderly patients with chronic obstructive pulmonary disease (COPD) and respiratory failure. Methods The clinical records of 94 elderly patients with COPD and respiratory failure who were treated in Yongkang First People's Hospital from February 2022 to January 2023 were retrospectively selected. Among them, 46 patients received HFNC alone (Control-group) and 48 patients received HFNC combined with BGF MDI (Study-group). The treatment effect, arterial blood gas status, pulmonary function, and acute physiology and chronic health evaluation (APACHE) II score before and after treatment were analyzed in both groups. Results The total efficacy of treatment in the Study-group (95.8%) was higher than that in the Control-group (78.3%) (P<0.05). After treatment, the partial pressure of arterial carbon dioxide (PaCO2), residual volume, and APACHE II scores in the two groups decreased compared to those before treatment, with the Study-group lower overall. However, arterial oxygen saturation (SaO2), oxygen partial pressure (PaO2), the percentage of peak expiratory flow (PEF), and forced expiratory volume in one second (FEV1) as percent of predicted (%FEV1) were higher than before treatment, and higher in the Study-group (P<0.05). Conclusions Compared with HFNC alone, BGF MDI combined with HFNC can effectively regulate the arterial blood gas status of elderly patients with COPD and respiratory failure, restore pulmonary function, and improve the overall treatment effect.

THE CLINICAL RESPIRATORY JOURNAL 2023; 17:1091-1102. [PMID: 37700578 PMCID: PMC10632084 DOI: 10.1111/crj.13695] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 08/01/2023] [Accepted: 08/29/2023] [Indexed: 09/14/2023]
Abstract
Chronic obstructive pulmonary disease can lead to acute hypercapnic respiratory failure (AHRF), often treated using noninvasive ventilation (NIV). Emerging research suggests the potential utility of high flow nasal cannula (HFNC) for AHRF. This systematic review and meta-analysis aimed to determine the effect of HFNC versus NIV on AHRF management. A search of electronic databases (CINAHL, MEDLINE, and Academic Search Complete), web sources, and trial registries was last conducted on 9 February 2023. Quality and risk of bias assessments were conducted. Meta-analyses were used to synthesise data. Seven randomised controlled trials were included. No statistically significant differences between HFNC and NIV were found within the following outcomes of interest: (i) correction of pCO2: standardised mean difference (SMD) = -0.16, 95% confidence interval (CI) (-0.34 to 0.02), p = 0.08; (ii) correction of pH: SMD = -0.05, 95% CI (-0.25 to 0.14), p = 0.59; (iii) correction of pO2: SMD = -0.15, 95% CI (-0.40 to 0.09), p = 0.22; (iv) intubation rates: risk ratio (RR) = 0.87, 95% CI (0.41 to 1.82), p = 0.71; (v) mortality rates: RR = 0.85, 95% CI (0.47 to 1.56), p = 0.61; and (vi) treatment switch: RR = 1.30, 95% CI (0.43 to 3.94), p = 0.64. More controlled trials with large sample sizes are required to investigate the management of AHRF of various aetiologies. HFNC may be used as a final exhaustive measure for COPD-related AHRF where NIV is not tolerated, and when it is not clinically indicated to extend to endotracheal intubation.

Abstract
COPD is a progressive inflammatory process affecting both the airways and alveolar structures of the lungs. Exacerbations of COPD are episodes of acute worsening of this inflammatory process, often triggered by infections. The most severe exacerbations are characterized by substantial air trapping and inspiratory muscle overload, which leads to hypercapnic respiratory failure. Pharmacologic therapies focus on intense bronchodilator administration (usually by aerosol), corticosteroids, and antibiotics. Respiratory life support technologies are often needed for severe exacerbations and range from carefully titrated supplemental O2 administration to positive-pressure ventilation (both invasive and noninvasive). Future life support strategies will likely involve extracorporeal life support technologies.

Abstract
Purpose We aimed to evaluate whether high flow nasal cannula (HFNC) is an effective and safe method for adult patients with acute hypercapnic respiratory failure (AHRF). Methods We searched the Cochrane Library, Embase, and PubMed databases from inception to August 2022 to obtain randomized controlled trials (RCTs) that compared HFNC with conventional oxygen treatment (COT) or non-invasive ventilation (NIV) in patients with AHRF, and then performed a meta-analysis. Results A total of ten parallel RCTs with 1265 individuals were identified. Of them, two studies compared HFNC with COT and eight studies compared HFNC with NIV. In terms of intubation rate, mortality, and arterial blood gas (ABG) improvement, HFNC showed comparable effects to NIV and COT. However, HFNC was more comfortable (mean difference [MD] -1.87, 95% confidence interval [CI] =-2.59, -1.15, P <0.00001, I2 =0%) and resulted in fewer adverse events (odds ratio [OR] 0.12, 95% CI=0.06, 0.28, P<0.00001, I2 = 0%), compared with NIV. In comparison to NIV, HFNC could significantly lower heart rate (HR) (MD -4.66, 95% CI=-6.82, -2.50, P <0.0001, I2 =0%), respiratory rate (RR) (MD -1.17, 95% CI=-2.03, -0.31, P =0.008, I2 =0%), and hospital stay length (MD -0.80, 95% CI=-1.44, -0.16, P =0.01, I2 =0%). NIV showed a decreased frequency in the treatment crossover rate, compared with HFNC in patients with pH<7.30 (OR 5.78, 95% CI=1.50, 22.31, P = 0.01, I2: not applicable). Contrary to COT, HFNC could considerably reduce the need for NIV (OR 0.57, 95% CI=0.35, 0.91, P=0.02, I2=0%). Conclusion HFNC was effective and safe in patients with AHRF. However, in patients with pH <7.30, HFNC may result in a higher incidence of treatment crossover, compared with NIV. Compared to COT, HFNC may decrease the need for NIV in patients with compensated hypercapnia.

Abstract
INTRODUCTION High-flow nasal cannula (HFNC) has been proven to improve oxygenation and avoid intubation in hypoxemic patients. It has also been utilized during endoscopy examination to reduce the incidence of hypoxia. However, little is known about the effects of HFNC versus conventional oxygen therapy (COT) on oxygenation during bronchoscopy examination via nasal route; particularly, no study has compared the use of HFNC with that of COT at similar FIO2 for patients who have high-risk factors of desaturation during bronchoscopy examination. METHODS AND ANALYSIS This randomized controlled trial will be implemented in four academic centers in China. Patients who have high-risk factors including hypoxemia, hypercapnia, morbid obesity, and narrow airway will be enrolled to use HFNC or COT during bronchoscopy examination. In the HFNC group, the initial gas flow will be set at 50 L/min with a fraction of inspired oxygen (FIO2) at 0.45, if the patient tolerates, the flow can be increased to 60L/min at most, while in the COT group, oxygen flow will be set at 6 L/min via a conventional nasal cannula. After 5 min pre-oxygenation, the bronchoscope will be inserted via the nasal route. Vital signs, oxygenation (SpO2), and transcutaneous CO2 (PtCO2) will be continuously monitored. The primary outcome is the incidence of hypoxemia, defined as SpO2 < 90% for 10 s during bronchoscopy examination, and secondary outcomes include the need for treatment escalation and adverse events. DISCUSSION Hypoxia is a common complication of bronchoscopy, our study attempted to demonstrate that HFNC may reduce the probability of hypoxia during bronchoscopy in high-risk patients. The results will be disseminated through peer-reviewed journals and national and international conferences. TRIAL REGISTRATION http://www.chictr.org.cn/ : ChiCTR2100055038.

Abstract
Objective To evaluate the clinical efficacy of high-flow nasal oxygen therapy (HFNC) and non-invasive ventilation (NIV) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) after extubation. Research Methods This systematic review and meta-analysis was conducted following the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) statements. The primary outcome measures analyzed included: reintubation rate, mortality, complication rate, and ICU length of stay. Results Eight studies were included, with a total of 612 subjects, including 297 in the HFNC group and 315 in the NIV group. The effect of HFNC and NIV on the reintubation rate of AECOPD patients after extubation, RR (1.49 [95% CI,0.95 to 2.33], P = 0.082). Subgroup analysis with or without hypercapnia according to the included AECOPD population, with hypercapnia, RR (0.69 [95% CI,0.33 to 1.44], P=0.317), without hypercapnia, RR (2.61 [95% CI,1.41 to 4.83], P=0.002). Mortality, RR (0.92 [95% CI,0.56 to 1.52], P = 0.752). ICU length of stay, MD (−0.44 [95% CI,-1.01 to 0.13], P = 0.132). Complication rate, RR (0.22 [95% CI,0.13 to 0.39], P = 0.000). After subgroup analysis, the reintubation rate of HFNC and NIV has no statistical difference in patients with hypercapnia, but NIV can significantly reduce the reintubation rate in patients without hypercapnia. In the outcome measures of complication rate, HFNC significantly reduced complication rate compared with NIV. In mortality and ICU length of stay, analysis results showed that HFNC and NIV were not statistically different. Conclusion According to the available evidence, the application of HFNC can be used as an alternative treatment for NIV after extubation in AECOPD patients with hypercapnia, but in the patients without hypercapnia, HFNC is less effective than NIV.

Abstract
High-flow nasal cannula (HFNC) has often been used in the treatment of acute respiratory failure during pulmonary rehabilitation setting. The aim of this retrospective study was to investigate the utility of HCFN during the early rehabilitation in COVID-19 pneumonia. Twenty-two patients (10 males and 12 females, mean age 64.5 ± 5.9 years) with COVID-19 pneumonia were considered. Medical data and rehabilitative scales were used to evaluate acute hypoxemic respiratory failure (PaO2/FiO2 < 300), treated with HFNC three times during evaluation. Overall clinical outcomes from the evaluation of the synergy between HFNC strategy and rehabilitation were evaluated. A statistically significant improvement was observed at T2 (and of treatment) in 1 minute sit to stand test (1STST) (4 ± 3 vs. 17 ± 5, p < 0.05), short physical performance battery (SPPB) (4.3 ± 2.81 vs. 9.15 ± 2.39, p < 0.05), SpO2% post effort (93 ± 1.26 vs. 98 ± 1.01, p < 0.05), respiratory rate post effort (RR) (24 ± 3.91 vs. 20 ± 3.13, p < 0.05), heart rate (HR) (97 ± 11.9 vs. 87 ± 9.17, p < 0.05), P/F rate (235 ± 7.35 vs. 331 ± 10.91, p < 0.05), SpO2 (86 ± 4.54 vs. 97 ± 1.01 p < 0.05), RR (20 ± 4 vs. 12 ± 1.39, p < 0.05). Then, treated HFNC patients showed a good improvement in physical performance at T2 and a good compliance with treatments proved to be extremely useful in the control and reduction of dyspnea and fatigue symptoms.
