Introduction Nasal polyposis (NP) is a chronic inflammatory condition of the upper airway characterized by overgrowth of nasal mucosa. Recent studies have shown a mechanical dysfunction in the nasal polyp tissue. Objective This study aims to evaluate the mechanical properties of nasal fibrotic tissue. Method This study was an institutional review board approved translational study in 20 partici...

Prevention of nosocomial pneumonia (NP) is the most important step towards reducing hospitalisation costs. The non-antibiotic prevention strategies include measures related to the correct care of the artificial airway, strategies related directly to the maintenance of the mechanical ventilator and the equipment, strategies focused in the gastrointestinal tract, and strategies related to the pos...

OBJECTIVE We aimed to examine the efficacy of medical masks and respirators in protecting against respiratory infections using pooled data from two homogenous randomised control clinical trials (RCTs). METHODS The data collected on 3591 subjects in two similar RCTs conducted in Beijing, China, which examined the same infection outcomes, were pooled. Four interventions were compared: (i) conti...

BACKGROUND Hospitalized, critically ill patients have a significant risk of developing nosocomial infection. Most episodes of nosocomial pneumonia occur in patients undergoing mechanical ventilation (MV). OBJECTIVE To ascertain the effect of an infection control program on rates of ventilator-associated pneumonia (VAP) in intensive care units (ICUs) in Argentina. METHODS All adult patients ...

BACKGROUND Ventilator-associated pneumonia (VAP) is a type of nosocomial pneumonia that occurs in patients who receive mechanical ventilation (MV). According to the International Nosocomial Infection Control Consortium (INICC), the overall rate of VAP is 13.6 per 1,000 ventilator days. The incidence varies according to the patient group and hospital setting. The incidence of VAP ranges from 13-...

Effective plant operating manuals used in a formal training program can make the difference between a successful operation and a failure. Once the plant process design and control strategies have been fixed, equipment has been ordered, and the plant is constructed, the only major variable affecting success is the capability of plant operating personnel. It is essential that the myriad details c...

we conducted this study to determine the risk of transmission of q fever to health care workers (hcws) during perioperative exposure to coxiella burnetii -infected thoracic endovascular aneurysm stent graft. pre-operative and 6-week post-operative phase i and ii igg q fever antibody titers were determined in 14 staff members of an operation room. the room had a negative pressure and all the mem...
