To the Editor: The emergence of Nipah virus (NiV) in Malaysia in 1999 resulted in 265 known human infections (105 fatal), widespread infection in pigs (with >1 million culled to control the outbreak), and the collapse of the Malaysian pig export market (1). As with the closely related Hendra virus (HeV) that emerged in Australia in 1994 and caused fatal disease in horses and humans (2), bats of...
BACKGROUND The utilization of noninvasive ventilation (NIV) in the Veterans Affairs health-care system is not well characterized. A survey of physicians and respiratory therapists was conducted to better understand its use. METHODS Three hospitals in each of 21 Veterans Affairs networks were selected based on severity of patient mix, level of staffing and workload. A request was sent via e-ma...
When used as a driving gas during NIV in hypercapnic COPD exacerbation, a helium-oxygen (He/O2) mixture reduces the work of breathing and gas trapping. The potential for He/O2 to reduce the rate of NIV failure leading to intubation and invasive mechanical ventilation has been evaluated in several RCTs. The goal of this meta-analysis is to assess the effect of NIV driven by He/O2 compared to air...
BACKGROUND Noninvasive ventilation (NIV) is frequently used for the management of acute respiratory failure (ARF) in very old patients (≥ 80 years), often in the context of a do-not-intubate order (DNI). We aimed to determine its efficacy and long-term outcome. METHODS Prospective cohort of all patients admitted to the medical ICU of a tertiary hospital during a 2-year period and managed usin...
Non-invasive ventilation in obesity hypoventilation syndrome without severe obstructive sleep apnoea
BACKGROUND Non-invasive ventilation (NIV) is an effective form of treatment in patients with obesity hypoventilation syndrome (OHS) who have concomitant severe obstructive sleep apnoea (OSA). However, there is a paucity of evidence on the efficacy of NIV in patients with OHS without severe OSA. We performed a multicentre randomised clinical trial to determine the comparative efficacy of NIV ver...
The fusion (F) proteins of Newcastle disease virus (NDV) and Nipah virus (NiV) are both triggered by binding to receptors, mediated in both viruses by a second protein, the attachment protein. However, the hemagglutinin-neuraminidase (HN) attachment protein of NDV recognizes sialic acid receptors, whereas the NiV G attachment protein recognizes ephrinB2/B3 as receptors. Chimeric proteins compos...
BACKGROUND Respiratory insufficiency in COPD may present as hypoxic and/or hypercapnic respiratory failure treated with long-term oxygen therapy (LTOT) and/or noninvasive ventilation (NIV) with LTOT. The Severe Respiratory Insufficiency Questionnaire (SRI) is a tool for the assessment of health-related quality of life (HRQOL) in subjects receiving NIV. However, it remains unclear whether the SR...
BACKGROUND Long-term home noninvasive mechanical ventilation (NIV) is beneficial in COPD but its impact on inflammation is unknown. We assessed the hypothesis that NIV modulates systemic and pulmonary inflammatory biomarkers in stable COPD. METHODS Among 610 patients referred for NIV, we shortlisted those undergoing NIV versus oxygen therapy alone, excluding subjects with comorbidities or non...
Long-term non-invasive ventilation (NIV) is a common modality of breathing support used for a range of sleep and respiratory disorders. The aim of this scoping review was to provide a summary of the literature relevant to long-term NIV use in children. We used systematic methodology to identify 11,581 studies with final inclusion of 289. We identified 76 terms referring to NIV; the most common ...
first-line treatment to improve gas exchange (89%) and was a valid tool as support to clearance techniques (68%) and to exercise training (43%). The main criteria to propose NIV, according to physiotherapists who use NIV (n528), were hypercapnic pulmonary exacerbation, awaiting lung transplantation, severe impairment of pulmonary function and difficulties experienced with clearing secretions (f...
