Evaluating the forced oscillation technique in the detection of early smoking-induced respiratory changes

<p>Abstract</p> <p>Background</p> <p>Early detection of the effects of smoking is of the utmost importance in the prevention of chronic obstructive pulmonary disease (COPD). The forced oscillation technique (FOT) is easy to perform since it requires only tidal breathing and offers a detailed approach to investigate the mechanical properties of the respiratory system. The FOT was recently suggested as an attractive alternative for diagnosing initial obstruction in COPD, which may be helpful in detecting COPD in its initial phases. Thus, the purpose of this study was twofold: (1) to evaluate the ability of FOT to detect early smoking-induced respiratory alterations; and (2) to compare the sensitivity of FOT with spirometry in a sample of low tobacco-dose subjects.</p> <p>Methods</p> <p>Results from a group of 28 smokers with a tobacco consumption of 11.2 ± 7.3 pack-years were compared with a control group formed by 28 healthy subjects using receiver operating characteristic (ROC) curves and a questionnaire as a gold standard. The early adverse effects of smoking were adequately detected by the absolute value of the respiratory impedance (<it>Z4Hz</it>), the intercept resistance (<it>R0</it>), and the respiratory system dynamic compliance (<it>Crs, dyn</it>). <it>Z4Hz </it>was the most accurate parameter (Se = 75%, Sp = 75%), followed by <it>R0 </it>and <it>Crs, dyn</it>. The performances of the FOT parameters in the detection of the early effects of smoking were higher than that of spirometry (p < 0.05).</p> <p>Conclusion</p> <p>This study shows that FOT can be used to detect early smoking-induced respiratory changes while these pathologic changes are still potentially reversible. These findings support the use of FOT as a versatile clinical diagnostic tool in aiding COPD prevention and treatment.</p

Currents issues in cardiorespiratory care of patients with post-polio syndrome

Post-polio syndrome (PPS) is a condition that affects polio survivors years after recovery from an initial acute attack of the poliomyelitis virus. Most often, polio survivors experience a gradual new weakening in muscles that were previously affected by the polio infection. The actual incidence of cardiovascular diseases (CVDs) in individuals suffering from PPS is not known. However, there is a reason to suspect that individuals with PPS might be at increased risk. Method: A search for papers was made in the databases Bireme, Scielo and Pubmed with the following keywords: post polio syndrome, cardiorespiratory and rehabilitation in English, French and Spanish languages. Although we targeted only seek current studies on the topic in question, only the relevant (double-blind, randomized-controlled and consensus articles) were considered. Results and Discussion: Certain features of PPS such as generalized fatigue, generalized and specific muscle weakness, joint and/or muscle pain may result in physical inactivity deconditioning obesity and dyslipidemia. Respiratory difficulties are common and may result in hypoxemia. Conclusion: Only when evaluated and treated promptly, somE patients can obtain the full benefits of the use of respiratory muscles aids as far as quality of life is concerned.Ctr Univ Augusto Motta, Programa Posgrad Ciencias Reabilitacao, Rio De Janeiro, RJ, BrazilUniv Severino Sombra, Fac Med, Vassouras, RJ, BrazilUniv Fed Rio de Janeiro, Inst Psiquiatria, Lab Mapeamento Cerebral & EEG, BR-22290140 Rio De Janeiro, RJ, BrazilUniv Fed Fluminense, Hosp Univ Antonio Pedro, Niteroi, RJ, BrazilInst Fed Educ Ciencia & Tecnol Rio de Janeiro, Curso Fisioterapia, Rio De Janeiro, RJ, BrazilUniv Fed Piaui, Parnaiba, PI, BrazilUniv Fed Sao Paulo, Dept Neurol, Sao Paulo, SP, BrazilUniv Fed Sao Paulo, Dept Neurol, Sao Paulo, SP, BrazilWeb of Scienc

Care after premenopausal risk-reducing salpingo-oophorectomy in high-risk women: Scoping review and international consensus recommendations

Women at high inherited risk of ovarian cancer are offered risk-reducing salpingo-oophorectomy (RRSO) from age 35 to 45 years. Although potentially life-saving, RRSO may induce symptoms that negatively affect quality of life and impair long-term health. Clinical care following RRSO is often suboptimal. This scoping review describes how RRSO affects short- and long-term health and provides evidence-based international consensus recommendations for care from preoperative counselling to long-term disease prevention. This includes the efficacy and safety of hormonal and non-hormonal treatments for vasomotor symptoms, sleep disturbance and sexual dysfunction and effective approaches to prevent bone and cardiovascular disease
