OBJECTIVE to examine the effect of cycle phase or a low dose oral contraceptive on exercise performance in young women. METHODS As controls, 15 men were tested twice by a maximal treadmill test (Vo2 max) and by an endurance run 14 d apart to determine performance variability from causes other than hormonal fluctuations. Ten women ages 18-30 were then tested for Vo2 max and endurance in the sa...

UNLABELLED The prognostic value of exercise oscillatory breathing (EOB) during cardiopulmonary test (CPX) has been described in young chronic heart failure (HF) patients. We assessed the prognostic role of EOB vs other clinical and ventilatory parameters in elderly HF patients performing a maximal CPX. METHODS AND RESULTS We prospectively followed-up 370 HF outpatients ≥ 65 years after a symp...

background: pain is described as the fifth vital sign, and inadequate pain management is linked to numerous immediate and long-term negative outcomes. venipuncture is one of the most painful medical procedures in children. distraction is one of the most effective ways to relieve pain. reducing patients’ pain is important for all nurses for many reasons. unnecessary pain can damage the nurse-pat...

A pilot study was conducted to evaluate the efficacy of 5-minute mindful breathing in distress reduction. Twenty palliative care patients and family caregivers with a distress score ≥4 measured by the Distress Thermometer were recruited and randomly assigned to mindful breathing or "listening" (being listened to). Median distress reductions after 5 minutes were 2.5 for the mindful breathing gro...

have been used for more than 30 years for heat and moisture retention during general anesthesia. Studies about bacteriostatic vs nonbacteriostatic HMEs (BHMEs/ NHMEs) have been conducted to assess their role in preventing bacterial transmission to the anesthesia breathing circuit; none have been done on anesthetized patients in the operating room. The present study adds to existing knowledge ab...

OBJECTIVE To determine whether there is a correlation between halitosis and mouth breathing in children. STUDY DESIGN Fifty-five children between 3 and 14 years of age were divided into two groups (nasal and mouth breathing) for the assessment of halitosis. A descriptive analysis was conducted on the degree of halitosis in each group. The chi-square test was used for comparison between groups...

introduction: hydrogen fluoride is one of the materials which is widely used in making glass, cleaning  silicon, manufacturing florescent lamps, ceramics and also in separating uranium isotopes. on the other hand, exposure to this substance could cause health problems including eye, nose, throat and mucus membranes irritation. this study examines the relationship between fluoride (f) in the uri...

BACKGROUND The mechanisms underlying breathing exercises have not been fully elucidated. OBJECTIVES To evaluate the impact of four on breathing exercises (diaphragmatic breathing, inspiratory sighs, sustained maximal inspiration and intercostal exercise) the on breathing pattern and thoracoabdominal motion in healthy subjects. METHOD Fifteen subjects of both sexes, aged 23 ± 1.5 years old a...

Objective To assess whether the spontaneous breathing test can predict the extubation failure in pediatric population. Methods A prospective and observational study that evaluated data of inpatients at the Pediatric Intensive Care Unit between May 2011 and August 2013, receiving mechanical ventilation for at least 24 hours followed by extubation. The patients were classified in two groups: Te...

UNLABELLED In recent decades, many studies on mouth breathing (MB) have been published; however, little is known about many aspects of this syndrome, including severity, impact on physical and academic performances. OBJECTIVE Compare the physical performance in a six minutes walk test (6MWT) and the academic performance of MB and nasal-breathing (NB) children and adolescents. METHOD This is...
