What do cochrane systematic reviews say about interventions for enuresis in children and adolescents? An overview of systematic reviews.

OBJECTIVE: To conduct an overview of Cochrane systematic reviews about treatment alternatives for children and/or adolescents with enuresis. SOURCES: An overview of Cochrane systematic reviews about interventions for enuresis in children/adolescents was developed between September/2021 and December/2021. The protocol was registered on PROSPERO and the search was conducted only in the Cochrane Library database without any restriction. Reviews involving any type of intervention for the treatment of enuresis in children/adolescents were included. The risk of bias was assessed using Risk of Bias in Systematic Reviews (ROBIS) and the quality of reviews was assessed using A Measurement Tool to Assess Systematic Reviews (AMSTAR-2). SUMMARY OF THE FINDINGS: Seven systematic reviews were identified. Based on the ROBIS assessment, all reviews were classified as low risk of bias. According to the AMSTAR-2 assessment, the three oldest systematic reviews were rated as critically low quality, one review was moderate quality, and the three most recent systematic reviews were rated as high quality. No difference was shown between alarm and desmopressin for a complete response to therapy after treatment (RR = 1.30; 95%CI: 0.92 to 1.84), but alarm use is related to a lower risk of adverse events (RR = 0.38; 95%CI: 0.20 to 0.71). There is a moderate certainty that the association between imipramine and oxybutynin is better than placebo to reduce the risk of children who do not achieve 14 consecutive dry nights after treatment (RR = 0.43; 95%CI: 0.23 to 0.78). CONCLUSIONS: There is no difference between alarm and desmopressin for enuresis treatment. However, alarm therapy had fewer adverse events than desmopressin. Moreover, combination therapy between imipramine and oxybutynin is better than placebo.

Clinical safety and hemodynamic, cardiac autonomic and inflammatory responses to a single session of inspiratory muscle training in obstructive sleep apnea.

PURPOSE: To determine clinical safety and cardiovascular, cardiac autonomic and inflammatory responses to a single session of inspiratory muscle training (IMT) in obstructive sleep apnea (OSA) subjects. METHODS: In a randomized controlled trial individuals of both sexes, aged between 30 and 70 years old with diagnosis of moderate to severe OSA were enrolled. Volunteers with OSA (n = 40) performed an IMT session with three sets of 30 repetitions with a 1-min interval between them. The IMT group (n = 20) used a load of 70% of the maximum inspiratory pressure (MIP), and the placebo group (n = 20) performed the IMT without load. Measurements of systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), heart rate variability (HRV), and inflammatory markers were performed pre, post-immediate and 1 h after the IMT session. RESULTS: No differences were shown in SBP, DBP, HRV, or inflammatory markers at any of the intervals analyzed. However, HR in the IMT group was lower ​​1 h after the IMT session compared to the pre-session values ​​(p = 0002). HR was higher in the placebo group when comparing pre × post-immediate (p < 0.001). HR decreased after the first hour in relation to the pre (p < 0.001) and post-immediate (p < 0.001) values. CONCLUSION: IMT sessions promote discreet hemodynamic, cardiac autonomic and inflammatory responses. Therefore, IMT is considered clinically safe and can be performed at home, guided but unsupervised, with lower cost and greater adherence to exercise program for subjects with OSA.

Inspiratory Muscle Training in the Severity of Obstructive Sleep Apnea, Sleep Quality and Excessive Daytime Sleepiness: A Placebo-Controlled, Randomized Trial.

PURPOSE: Exercise programs have been considered as an adjuvant treatment in obstructive sleep apnea (OSA). However, few studies have focused on the effects of the inspiratory muscle training (IMT) in reducing the severity and the symptoms of OSA. PATIENTS AND METHODS: A randomized controlled trial was conducted and approved by the local Ethics Committee. All subjects signed the informed consent form and were randomized into 2 groups: a) IMT group (n = 8), 8 weeks of IMT with 75% of maximal inspiratory pressure (MIP) and b) placebo group (n = 8): subjects performed IMT without load. RESULTS: IMT group showed reduction in the apnea-hypopnea index (AHI) (p = 0.01), in the Berlin questionnaire score (p = 0.001) and an increase in inspiratory muscle strength (p = 0.018). IMT group demonstrated a reduction in the AHI (31.7 ± 15.9 events/h vs 29.9 ± 15.8 events/h; p <0.001), in the Berlin questionnaire scores (2.6 ± 0.5 vs 1.2 ± 0.5; p = 0.016), Pittsburgh Sleep Quality Index (PSQI) score (7.2 ± 3.6 vs 3.7 ± 1.3; p = 0.008), in the Epworth Sleepiness Scale (ESS) (12.5 ± 4.0 vs 7.7 ± 3.0; p = 0.008) and increase in MIP (83.6 ± 26.5 cmH2O and 127.9 ± 32.5 cmH2O; p = 0.010). CONCLUSION: The IMT promotes discrete changes in the AHI and improves sleep quality and excessive daytime sleepiness in OSA. Moreover, IMT is a cheap, useful and simple home-based training program and can be considered as an adjunct therapy for OSA patients.

"Posterior Tibial Nerve" or "Tibial Nerve"? Improving the reporting in health papers.

AIMS: The primary objective of this study is to identify which term is the most appropriate to use according to anatomical nomenclature: "posterior tibial nerve" or "tibial nerve." Furthermore, this paper intends to show how the use of these terms in papers indexed in important health databases is numerous and to describe the anatomical characteristics of such nerve, to improve future scientific publications. METHODS: This is a descriptive study about the importance of standardizing the use of the terms "posterior tibial nerve" and "tibial nerve" and its anatomy. It comprises three phases: the first is a search in the main databases to identify the use of the terms "posterior tibial nerve" and "tibial nerve." The second phase refers to the consultation of international anatomical terminology to identify the most appropriate term to refer to the nerve, while the third phase is related to the study of the anatomy of this nerve. RESULTS: The term "tibial nerve" is more commonly used, but the use of the term "posterior tibial nerve" is still very substantial. According to international anatomical terminology, the correct term is "tibial nerve," which is a branch of the sciatic nerve. CONCLUSIONS: "Tibial nerve" is the term standardized by international anatomical terminology. The use of terms in accordance with Terminologia Anatomica is important to facilitate the process of teaching and learning, as well as to improve the reporting and interpretation of papers regarding health, and the evidence-based clinical practice.

Effectiveness of inspiratory muscle training on sleep and functional capacity to exercise in obstructive sleep apnea: a randomized controlled trial.

PURPOSE: The aim of this study was to evaluate the effectiveness of inspiratory muscle training (IMT) on sleep and functional capacity to exercise in subjects with obstructive sleep apnea (OSA). METHODS: This is a controlled, randomized, double-blind study conducted in 16 OSA patients divided into two groups: training (IMT: n = 8) and placebo-IMT (P-IMT: n = 8). IMT was conducted during 12 weeks with a moderate load (50-60% of maximal inspiratory pressure-MIP), while P-IMT used a load < 20% of MPI. Total daily IMT time for both groups was 30 min, 7 days per week, twice a day. RESULTS: There was no difference comparing IMT to P-IMT group after training for lung function (p > 0.05) and respiratory muscle strength (p > 0.05). Maximal oxygen uptake (VO2Max) was not significantly different between IMT and P-IMT group (mean difference - 1.76, confidence interval (CI) - 7.93 to 4.41, p = 0.71). The same was observed for the other ventilatory and cardiometabolic variables measured (p > 0.05). A significant improvement in sleep quality was found when Pittsburgh Sleep Quality Index (PSQI) values of IMT and P-IMT group after training were compared (mean difference: 3.7, confidence interval 95% (CI95%) 0.6 to 6.9, p = 0.02) but no significant changes were seen in daytime sleepiness between both groups after the intervention (mean difference: 3.4, CI 95%: - 3.3 to 10.0; p = 0.29). CONCLUSION: According to these results, 12 weeks of moderate load IMT resulted in improved sleep quality, but there were no significant repercussions on functional capacity to exercise or excessive daytime sleepiness.

Obstructive sleep apnea does not impair cardiorespiratory responses to progressive exercise performed until exhaustion in hypertensive elderly.

BACKGROUND: Elderly people have a high prevalence to systemic arterial hypertension (SAH) and obstructive sleep apnea (OSA). Both comorbidities are closely associated and inflict damage on cardiorespiratory capacity. METHODS: In order to assess cardiorespiratory responses to the cardiopulmonary exercise test (CPET) among hypertensive elderly with OSA, we enrolled 28 subjects into two different groups: without OSA (No-OSA: apnea/hypopnea index (AHI) < 5 events/h; n = 15) and with OSA (OSA: AHI ≥ 15 events/h; n = 13). All subjects underwent CPET and polysomnographic assessments. After normality and homogeneity evaluations, independent t test and Pearson's correlation were performed. The significance level employed was p ≤ 0.05. RESULTS: Hypertensive elderly with OSA presented lower heart rate recovery (HRR) in the second minute (HRR2) in relation to the No-OSA group. A negative correlation between AHI and ventilation (VE) (r = -0.63, p = 0.02) was found in polysomnography and CPET data comparisons, and oxygen saturation (O2S) levels significantly correlated with VE/VCO2slope (r = 0.66, p = 0.01); in addition, OSA group presented a positive correlation between oxygen consumption and O2S (r = 0.60, p = 0.02), unlike the no-OSA group. CONCLUSIONS: OSA does not affect the CPET variables in hypertensive elderly, but it attenuates the HRR2. The association between O2S during sleep with ventilatory responses probably occurs due to the adaptations in the oxygen transport system unleashed via mechanical respiratory feedback; thus, it has been identified that OSA compromises the oxygen supply in hypertensive elderly.

[The role of respiratory physiotherapy in the lung function of obese patients undergoing bariatric surgery. A review]. / Intervenção da fisioterapia respiratória na função pulmonar de indivíduos obesos submetidos a cirurgia bariátrica. Uma revisão.

INTRODUCTION: Obesity, considered a new worldwide epidemic, is characterised by excess adipose tissue and contributes to a series of chronic diseases and increased mortality. Obesity associated to surgical procedure in these patients makes respiratory physiotherapy a must to recover lung function and prevent postoperative pulmonary complications. AIMS: To assess the effects of respiratory physiotherapy on the lung function of obese patients undergoing weight loss surgery. MATERIAL AND METHODS: We conducted a literature review October 2008-June 2009 of data which had been published over the last thirty years and which was available on the Medline, Pubmed ans Scielo databases. CONCLUSION: Pre- and postoperative respiratory physiotherapy is vital for patients undergoing weight loss surgery irrespective of technique used, as it can prevent pulmonary complications inherent in the surgical procedure and aid lung function recovery.

Effects of nasal continuous positive airway pressure treatment on oxidative stress and adiponectin levels in obese patients with obstructive sleep apnea.

BACKGROUND: Obesity and obstructive sleep apnea (OSA) are both associated with the prevalence of major cardiovascular illnesses and certain common factors they are considered responsible for, such as stress oxidative increase, sympathetic tonus and resistance to insulin. OBJECTIVE: The aim of the present study was to compare the effect of continuous positive airway pressure (CPAP) on oxidative stress and adiponectin levels in obese patients with and without OSA. METHODS: Twenty-nine obese patients were categorized into 3 groups: group 1: 10 individuals without OSA (apnea-hypopnea index, AHI or=20) who did not use CPAP; group 3: 9 patients with moderate to severe OSA (AHI >or=20) who used CPAP. RESULTS: Group 3 showed significant differences before and after the use of CPAP, in the variables of diminished production of superoxide, and increased nitrite and nitrate synthesis and adiponectin levels. Positive correlations were seen between the AHI and the superoxide production, between the nitrite and nitrate levels and the adiponectin levels, between superoxide production and the HOMA-IR, and between AHI and the HOMA-IR. Negative correlations were found between AHI and the nitrite and nitrate levels, between the superoxide production and that of nitric oxide, between the superoxide production and the adiponectin levels, between AHI and the adiponectin levels, and between the nitrite and nitrate levels and the HOMA-IR. CONCLUSIONS: This study demonstrates that the use of CPAP can reverse the increased superoxide production, the diminished serum nitrite, nitrate and plasma adiponectin levels, and the metabolic changes existing in obese patients with OSA.
