BACKGROUND Intermittent positive-pressure ventilation (IPPV) is the "gold standard" of ventilation during cardiopulmonary resuscitation (CPR), but continuous positive airway pressure (CPAP) is increasingly discussed as an alternative. This study investigated hemodynamics and pulmonary gas exchange applying CPAP enhanced with pressure support ventilation (CPAP(PSV)) during CPR. METHODS AND RES...

CPAP--a gene mutated in primary microcephaly--is required for procentriole formation. Here we show that CPAP degradation and function is controlled by the poly(ADP-ribose) polymerase tankyrase 1. CPAP is PARsylated by tankyrase 1 in vitro and in vivo. Overexpression of tankyrase 1 leads to CPAP proteasomal degradation, preventing centriole duplication, whereas depletion of tankyrase 1 stabilize...

AIM To assess the effect of nasal continuous positive airways pressure (CPAP) on the dimensions of the laryngeal opening. METHODS Nine preterm infants who had previously received ventilatory support for respiratory distress syndrome (RDS) were studied. All were receiving nasal CPAP. The laryngeal opening was visualised using a fibre optic video camera system. The ratio of width to length of t...

Despite the acknowledged clinical usefulness of nasal CPAP, uncertainties regarding aspects of its application remain. Clinical indications for the application of nasal CPAP vary greatly between institutions. Furthermore, defining the optimal nasal CPAP system is complicated by the multiplicity of nasal CPAP devices and techniques available to the clinician. This review aims to identify what we...

Metastasis to lymph nodes and distant organs is the main challenge in the treatment of papillary thyroid cancer. In the current investigation, we aimed to evaluate the synergistic effects of celecoxib (CX) and sodium valproate (VPA) against cell survival, invasiveness properties, and expression of metalloproteinase-2 and -9 (MMP-2 and MMP-9) in  papillary thyroid cancer cell line, BCPAP cells. ...

BACKGROUND Continuous Positive Airway Pressure (CPAP) is a commonly accepted method of spontaneous breathing support in obstructive lung disease. Previous work suggested that the cause of the CPAP efficacy in the obstructive lung disease localized in bronchi of middle order (OLDMO) is not as obvious as, for example, in the obstructive sleep apnea. Since CPAP reduces obstruction and the optimal ...

STUDY OBJECTIVES To assess predictive factors of quality-of-life (QoL) improvement and continuous positive airway pressure (CPAP) use in patients with sleep apnea-hypopnea syndrome (SAHS) after 1 year of treatment with CPAP. DESIGN Observational, prospective cohort study. SETTING Sleep unit in a university hospital. PATIENTS One hundred thirty-three consecutive patients with an indication...

BACKGROUND Obstructive sleep apnea (OSA) is associated with increased risk of cardiovascular diseases. Although CPAP is the first treatment choice for moderate-to-severe OSA, acceptance of and adherence to CPAP remain problematic. High CPAP adherence is generally defined as ≥4 h of use/night for ≥70% of the nights monitored. We investigated the long-term beneficial effects of CPAP on sleep qual...

CPAP should be considered the first line of treatment in patients with moderate to severe obstructive sleep apnoea. In our centre in Sydney this generally means patients with more than 20 apnoea/hypopnoeas per hour with repeated dips in oxyhaemoglobin saturation and usually some symptomatology. Despite this first line role of nasal CPAP, recent objective studies question whether earlier enthusi...

Adaptive servo-ventilation (ASV) has been attracting attention as a novel respiratory support therapy for heart failure (HF). However, the acute hemodynamic effects have not been compared between ASV and continuous positive airway pressure (CPAP) in HF patients.We studied 12 consecutive patients with stable chronic HF. Hemodynamic measurement was performed by right heart catheterization before ...
