Review Meta Analysis
Frequency of Signs and Symptoms in Persons With Asthma.
Signs and symptoms of asthma are well established; however, no study has been performed to rank them. Therefore, we performed this systematic review and meta-analysis to determine the pooled frequencies of different signs and symptoms of asthma in subjects age ≥ 14 y to develop a patient-specific questionnaire. ⋯ Asthma severity was dependent on variety of symptoms, consisting mostly of wheezing, breathlessness, chest tightness, and cough. On the basis of our analysis, we recommend a combination of symptoms be included in diagnostic-based questionnaires to aid early diagnosis.

Randomized Controlled Trial
Physical Exercise Combined With CPAP in Subjects Who Underwent Surgical Myocardial Revascularization: A Randomized Clinical Trial.
Aerobic exercise and CPAP benefit patients in the postoperative period of cardiac surgery. To our knowledge, the association of aerobic exercise on an exercise bicycle with CPAP has not yet been demonstrated. Therefore, we aimed to evaluate the effectiveness of physical exercise on a cycle ergometer combined with CPAP in the postoperative period after coronary artery bypass graft surgery. ⋯ Physical exercise combined with CPAP promoted the maintenance of functional capacity and reduced the length of stay in the ICU.

Observational Study
Prevalence of and Risk Factors for Mechanical Ventilation Reinstitution in Patients Weaned From Prolonged Mechanical Ventilation.
Prolonged mechanical ventilation is increasingly common in ICUs. Although a consensus conference defined weaning success in this patient population, few studies have used this definition. A clear definition of successful weaning is useful to assess clinical and epidemiological outcomes, facilitate clinical decision making, and set goals of care. The aims of our study were to describe the prevalence of reinstitution of mechanical ventilation within 28 d in patients successfully weaned according to our institution criterion (ie, weaning success as per consensus guidelines), to describe reasons to reestablish mechanical ventilation, and to identify associated factors. ⋯ Reinstitution of mechanical ventilation within 28 d is a common event in patients considered to be weaned: 1 in 5 of such patients requires reconnection to mechanical ventilation, with sepsis being the most prevalent cause. Neurological comorbidity and delayed weaning are risk factors associated with reestablishment of mechanical ventilation. The presence of more than one risk factor increases the association with reinstitution of mechanical ventilation within 28 d of weaning.

Auscultation is a fundamental part of the physical examination, but its utility has been questioned due to the low inter-rater concordance. We therefore sought to evaluate the concordance of the discrimination of lung sound recordings between experienced physiotherapists. ⋯ Concordance between physiotherapists in discriminating recorded lung sounds was moderate. The ability to recognize stridor was inversely associated with years of work experience.

Clinical preceptors in respiratory therapy (RT) are expected to possess effective teaching skills and qualities that signify their knowledge, expertise, and professionalism. Thus, it is important to determine which teaching characteristics are effective among RT clinical preceptors from the administrators' perspective as well as the predictors for the administrators' decisions. ⋯ This study indicates that the professional competence of clinical preceptors is believed by RT administrators to be the most important behavioral characteristic. The results also indicate that role modeling and showing genuine interest in patients and their care are the most effective teaching characteristics of clinical preceptors.
