BACKGROUND: For patients with sepsis receiving non-invasive ventilation (NIV), early rehabilitation is crucial. The Sitting Baduanjin (SBE) is an efficient early rehabilitation exercise suitable for bed patients. There is no consensus about the effect of SBE on the early rehabilitation of septic patients with NIV. This study focused on how the SBE affected the early rehabilitation of sepsis patients with NIV.
METHODS: 96 sepsis patients with NIV were randomly assigned to either an Baduanjin group that received the SBE based on the routine rehabilitation exercise (n = 48) or a control group (n = 48) that received routine rehabilitation exercise. The primary outcome was the Medical Research Council(MRC)score, and the Barthel Index score, the duration of NIV, length of ICU stay, length of total stay, hospitalization expense as secondary outcomes.
RESULTS: A total of 245 sepsis patients were screened, with 96 randomly assigned. The study was completed by 90 patients out of the 96 participants.Results revealed that the MRC score increased in both groups, but the improvement of muscle strength in Baduanjin group was more obvious, with statistical significance (p < 0.001).There was statistically significantly difference between the two groups in Barthel Index at the day of transfer out of ICU(P = 0.028).The patients in the Baduanjin group had an average reduction of 24.09 h in the duration of NIV and 3.35 days in total length of hospital stay compared with the control group (p < 0.05).Of note, the Baduanjin group had significantly reduction the total hospitalization expense. No serious adverse events occurred during the intervention period.
CONCLUSIONS: In patients with sepsis, the SBE appears to improve muscle strength and activities of daily living (ADL), and lowed the duration of NIV, the length of the total stay, and the hospitalization expense.

High-flow nasal cannula (HFNC) therapy has emerged as a significant advancement in respiratory support, offering a non-invasive alternative to traditional oxygen delivery methods in critical care settings. This review comprehensively evaluates HFNC therapy, focusing on its definition, historical evolution, and current clinical applications. HFNC therapy delivers humidified and heated oxygen at high flow rates through a nasal cannula, enhancing oxygenation and patient comfort. The review highlights the physiological mechanisms underlying HFNC and its efficacy in managing acute respiratory failure, chronic obstructive pulmonary disease exacerbations, and postoperative respiratory support. Key findings from clinical trials and meta-analyses are discussed, emphasizing HFNC\'s advantages over conventional methods, such as reduced intubation rates and shorter ICU stays. The review also addresses safety considerations, including potential risks and complications associated with HFNC therapy. Furthermore, it explores future directions for research and technological advancements aimed at optimizing HFNC use in diverse patient populations. This review aims to provide evidence-based insights to inform clinical practice and guide future investigations in respiratory therapy.

Heart failure (HF) is an increasingly prevalent disease in humans; it induces multiple symptoms and damages health. The animal gut microbiota has critical roles in host health, which might be related to HF symptoms. Currently, several options are used to treat HF, including non-invasive ventilation (NIV). However, studies on gut microbiota responses to acute HF and associated treatments effects on gut communities in patients are scarce. Here, short-term (1 week after treatments) and long-term (3 months after treatment) variations in gut microbiota variations in rats with acute HF treated were examined NIV through high-throughput sequencing of the bacterial 16S rRNA gene. Through comparison of gut microbiota alpha diversity, it was observed lower gut microbiota richness and diversity in animals with acute HF than in normal animals. Additionally, beta-diversity analysis revealed significant alterations in the gut microbiota composition induced by acute HF, as reflected by increased Firmicutes/Bacteroidetes (F/B) ratios and Proteobacteria enrichment. When network analysis results were combined with the null model, decreased stability and elevated deterministic gut microbiota assemblies were observed in animals with acute HF. Importantly, in both short- and long-term periods, NIV was found to restore gut microbiota dysbiosis to normal states in acute HF rats. Finally, it was shown that considerable gut microbiota variations existed in rats with acute HF, that underlying microbiota mechanisms regulated these changes, and confirmed that NIV is suitable for HF treatment. In future studies, these findings should be validated with different model systems or clinical samples.

BACKGROUND: Preterm infants often require non-invasive breathing support while their lungs and control of respiration are still developing. Non-invasive neurally adjusted ventilatory assist (NIV-NAVA) is an emerging technology that allows infants to breathe spontaneously while receiving support breaths proportional to their effort. This study describes the first Australian Neonatal Intensive Care Unit (NICU) experience of NIV-NAVA.
METHODS: Retrospective cohort study of infants admitted to a major tertiary NICU between October 2017 and April 2021 supported with NIV-NAVA. Infants were divided into three groups based on the indication to initiate NIV-NAVA (post-extubation; apnoea; escalation). Successful application of NIV-NAVA was based on the need for re-intubation within 48 h of application.
RESULTS: There were 169 NIV-NAVA episodes in 122 infants (82 post-extubation; 21 apnoea; 66 escalation). The median (range) gestational age at birth was 25 + 5 weeks (23 + 1 to 43 + 3 weeks) and median (range) birthweight was 963 g (365-4320 g). At NIV-NAVA application, mean (SD) age was 17 days (18.2), and median (range) weight was 850 g (501-4310 g). Infants did not require intubation within 48 h in 145/169 (85.2%) episodes [72/82 (87.8%) extubation; 21/21 (100%) apnoea; 52/66 (78.8%) escalation).
CONCLUSIONS: NIV-NAVA was successfully integrated for the three main indications (escalation; post-extubation; apnoea). Prospective clinical trials are still required to establish its effectiveness versus other modes of non-invasive support.

UNASSIGNED: NIV (Non-invasive ventilation) and HFNC (High Flow nasal cannula) are being used in patients with acute respiratory failure. HACOR score has been exclusively calculated for patients on NIV, on other hand ROX index is being used for patients on HFNC. This is first study where ROX index has been used in patients on NIV to predict failure.
UNASSIGNED: This study investigates the comparative diagnostic performance of HACOR score and ROX index to predict NIV failure.
UNASSIGNED: We performed a retrospective cohort study of non-invasively ventilated COVID-19 patients admitted between 1st April 2020 to 15th June 2021 to ICU of a tertiary care teaching hospital located in Central India. We assessed factors responsible for NIV failure, and whether these scores HACOR/ROX index have discriminative capacity to predict risk of invasive mechanical ventilation.
UNASSIGNED: Of the 441 patients included in the current study, 179 (40.5%) recovered, while remaining 262 (59.4%) had NIV failure. On multivariable analysis, ROX index > 4.47 was found protective for NIV-failure (OR 0.15 (95% CI 0.03-0.23; p<0.001). Age > 60 years and SOFA score were other significant independent predictors of NIV-failure. The AUC for prediction of failure rises from 0.84 to 0.94 from day 1 to day 3 for ROX index and from 0.79 to 0.92 for HACOR score in the same period, hence ROX score was non-inferior to HACOR score in current study. DeLong\'s test for two correlated ROC curves had insignificant difference expect day-1 (D1: 0.03 to 0.08; p=3.191e-05, D2: -0.002 to 0.02; p = 0.2671, D3: -0.003 to 0.04; p= 0.1065).
UNASSIGNED: ROX score of 4.47 at day-3 consists of good discriminatory capacity to predict NIV failure. Considering its non-inferiority to HACOR score, the ROX score can be used in patients with acute respiratory failure who are on NIV.

Neuromuscular diseases (NMDs) comprise a heterogeneous group of conditions characterized by extreme progressive muscle weakness leading to respiratory failure. Noninvasive mechanical ventilation (NIV) has emerged as a cornerstone in the management of respiratory complications associated with NMDs. This review aims to elucidate the role of NMV in respiratory function, improving quality of life, and prolonging survival in individuals with NMD. The physiological basis of respiratory impairment in NMDs, principles of NMV application, evidence supporting its efficacy, patient selection criteria, and potential challenges in its application are discussed.

UNASSIGNED: The functions of eating, drinking, speaking, and breathing demand close coordination of the upper airway musculature which may be challenged by the long-term use of daytime non-invasive ventilation (NIV). This rapid review explores the challenges and practicalities of these interactions in people with neuromuscular disorders.
UNASSIGNED: A search was performed on PubMed (period 2000-2023) using generic terms to refer to eating, drinking, and speaking related to people with neuromuscular disorders on NIV. A narrative approach was used to summarize the available literature.
UNASSIGNED: Our review shows only a small number of studies exist exploring the use of NIV on swallowing and speaking in people with neuromuscular disorders. We summarize study findings and provide practical advice on eating, drinking and speaking with NIV.
UNASSIGNED: By understanding breathing, NIV mechanics and upper airway interactions, it is possible to optimize swallowing and speaking whilst using NIV. There is a lack of specific guidelines, and concerns regarding aspiration warrant further research and guideline development.

The neuromuscular patients may experience the need for respiratory support due to the onset of respiratory failure. Some skills are essential to achieve therapeutic success. In addition to technical knowledge, it is essential to have knowledge relating to individual neuromuscular diseases. The availability of alternative respiratory supports and various interfaces can be a valuable weapon at different moments in the course of the neuromuscular disease. Furthermore, the doctor-patient relationship plays a key role as does taking care of the patient\'s psychological sphere.

UNASSIGNED: Acute systolic heart failure (ASHF) is one of the most serious complications of the acute coronary syndrome (ACS), and increases the likelihood of adverse clinical outcomes. It remains unclear whether the use of non-invasive ventilation (NIV) could improve symptoms and reduce mortality in patients with ASHF derived from ACS.
UNASSIGNED: Data on biological, clinical, and demographic factors, as well as therapy data, were collected from patients with ASHF in the cardiac department. A total of 1257 ACS patients with ASHF were included in the study. Patients were divided into two groups. The control group received standard oxygen therapy. The comparison group consisted of those who underwent NIV as part of their immediate care. During hospitalization and at follow-up, information on both groups was systematically compared.
UNASSIGNED: In comparison with the control group, mean 24-hour urine output was found to be significantly higher in the NIV group. A significant reduction in the duration of symptoms was observed among patients in the NIV group from the time of admission until relief of dyspnea. Heart rate, C-reactive protein, estimated glomerular filtration rate, and N-terminal prohormone of brain natriuretic peptide (NT-proBNP) was also improved, compared with those in the control group. The NIV group was found to have a higher survival rate. NIV was independently related to all-cause mortality in 1-year follow-up (hazard ratio, 0.674; p = 0.045).
UNASSIGNED: Our study shows that NIV, as compared with standard oxygen therapy, has a beneficial impact on heart rate, metabolic balance, and relief of dyspnea in ACS patients with ASHF which results in reduced intubation rate, duration of in-hospital stay, and 1-year mortality.

Respiratory dysfunction is an important hallmark of amyotrophic lateral sclerosis (ALS). Elevation of creatine kinase (CK) has been reported in 23-75% of ALS patients, but the underlying mechanisms remain unknown. This work aims to enlighten the role of CK as a prognostic factor of respiratory dysfunction in ALS. A retrospective analysis of demographic and clinical variables, CK, functional decline per month (ΔFS), forced vital capacity (%FVC), and mean amplitude of the phrenic nerve compound motor action potential (pCMAP) in 319 ALS patients was conducted. These measurements were evaluated at study entry, and patients were followed from the moment of first observation until death or last follow-up visit. High CK values were defined as above the 90th percentile (CK ≥ P90) adjusted to sex. We analyzed survival and time to non-invasive ventilation (NIV) as proxies for respiratory impairment. Linear regression analysis revealed that high CK was associated with male sex (p < 0.001), spinal onset (p = 0.018), and FVC ≥ 80% (p = 0.038). CK was 23.4% higher in spinal-onset ALS patients (p < 0.001). High CK levels were not linked with an increased risk of death (p = 0.334) in Cox multivariate regression analysis. CK ≥ P90 (HR = 1.001, p = 0.038), shorter disease duration (HR = 0.937, p < 0.001), lower pCMAP (HR = 0.082, p < 0.001), and higher ΔFS (HR = 1.968, p < 0.001) were risk factors for respiratory failure. The association between high CK levels and poorer respiratory outcomes could derive from cellular metabolic stress or a specific phenotype associated with faster respiratory decline. Our study suggests that CK measurement at diagnosis should be more extensively investigated as a possible marker of poor respiratory outcome in future studies, including a larger population of patients.
