OBJECTIVE The objective of this study was to evaluate the protective effects of a new device for reducing perineal tears during vaginal childbirth. STUDY DESIGN A multicenter open randomized controlled trial (RCT) was performed in Helsingborg, Lund and Malmö, Sweden consisting of 1148 women. Women anticipating a vaginal delivery were either randomized to the intervention group (n=574 in which...

Introduction: Different factors such as respiratory disorders , genetics, facial growth pattern , tongue malfunction and malposition are associated with anterior open bite. Skeletal open bite is often appeared by increased posterior dentoalveolar height of maxilla and backward rotation of mandible. Many treatment approaches have been developed for treatment of increased facial height problems. ...

INTRODUCTION Inoperable airway stenoses are currently treated by placing stents. A major problem of covered stents is missing mucociliary clearance, which is caused by covering the native respiratory epithelium. By coating a stent with respiratory epithelium, this problem can be overcome. However, no methods are available for efficient endoscopic cell seeding. METHODS We designed a flexible e...

BACKGROUND Monitoring of the electrocardiogram (ECG) in premature infants with conventional adhesive-backed electrodes can harm their sensitive skin. Use of an electrode belt prevents skin irritation, but the effect of belt pressure on respiratory function is unknown. A strain gauge sensor is described which measures applied belt tension. METHOD The device frame was comprised of an aluminum h...

To the Editor—In their recent study, Bischoff et al [1] exposed subjects to a small-particle aerosol of commercially available live attenuated influenza vaccine (LAIV; MedImmune LLC, Gai-thersburg, MD). LAIV was used as a proxy for wild-type influenza to evaluate the protection provided by N95 respirators, surgical masks, and eye protection. Although the study addresses the important question o...

adequately ventilate), or both hypoxic and hypercapnic. In addition, respiratory failure can be caused by an inability to protect the airway. Alterations in the normal physiology and anatomy of the respiratory system can lead to respiratory failure requiring mechanical ventilation. Anatomic alterations causing airway obstruction, such as tumors, edema, direct or indirect trauma, burns, or other...

We present three patients with respiratory failure in whom conventional mechanical lung ventilation resulted in unacceptably high levels of carbon dioxide, severe acidosis and high vasopressor requirements. A pumpless arteriovenous extracorporeal carbon dioxide removal device (Novalung) was inserted. Arterial carbon dioxide levels were reduced rapidly with a corresponding increase in pH, reduct...

Respiratory tract infections represent the main cause of death from infectious diseases worldwide. SARS-CoV-2 infection (i.e. COVID-19) added to existing global burden respiratory infections, including tuberculosis. Among nanomaterials for fabric functionalization, graphene, in combination with hydrophobic molecules such as phytochemicals, represents a promising low-cost alternative antibiotics...
