Background: Recent studies show that women on combined oral contraceptives (COC) present abnormal fasting lipid profile, increased postprandial lipemia, plasma C-reactive protein (CRP) and blood pressure (BP) compared to women not on combined oral contraceptives. Plasma renin is one of the factors responsible for abnormal BP.Objectives: To assess plasma renin levels in women using or not using COC, the correlation between renin and CRP, as well as divergences in lipid profile. Methods:A cross-sectional study with apparently healthy women aged 20 to 30, eutrophic, irregularly active, and with fasting triglycerides < 150 mg/dL. The sample was stratified into two groups: the No Combined Oral Contraceptive Group (NCOCG), comprised of women who did not use any type of hormone contraceptive, and the Combined Oral Contraceptive Group (COCG) comprised of women on low-dose COC for at least one year. After a 12-hour fast, 5 ml of blood was collected for renin dosing and PCR. Data were analyzed by the t-Test and bidirectional Mann-Whitney Test, both with significance < 0.05. Results:We evaluated 44 women equally distributed between the groups, age 23 ± 1.2 years, BMI 21.0 ± 3.2 kg/m 2 . Median and interquartile deviation of renin in the NCOCG and the COCG were, respectively, 0.5 (0.1-1.0) and 3.0 (2-6) (p < 0.01). A positive correlation between PCR and renin (p < 0.01 and r = 0.68) was found. Conclusion:The plasma renin levels of women using COC were higher, with a strong correlation with CRP.
Cardiovascular diseases are considered one of the main causes of death in the world and one of the forms of treatment is cardiac surgery, including myocardial revascularization. After the good results, the surgery is related to pulmonary complications, causing respiratory muscle dysfunction, loss of muscle strength and decreased lung capacities and volumes. Physiotherapy uses several techniques and inspiratory muscle training emerges as a technique that aims to improve respiratory muscle strength and endurance. The aim of this study was to describe the effects and importance of inspiratory muscle training in the treatment of pulmonary dysfunction in the postoperative period of coronary artery bypass graft surgery. This is a systematic literature review, carried out with controlled and randomized clinical trials, indexed in the Cochrane Library, Lilacs, PEDro, Pubmed and SciELO databases, published between 2009 and July 2021 in Portuguese, English and Spanish. 08 articles make up this review. It was concluded that inspiratory muscle training, although there is no specific protocol on how to perform it, proved to be a safe, easy to apply and effective technique in the treatment of pulmonary dysfunctions and of paramount importance for rehabilitation in the postoperative period of revascularization of the myocardium.

Introduction: Historically skeletal muscle strength has been the subject of numerous scientific investigations. Which, besides defining its role in health and disease process also identified neuromuscular mechanisms to modify it. Another interesting point is that in recent decades, authors have suggested that neural mobilization techniques can modify the neuromuscular physiology, however, little is known about its effects on muscle strength. Objective: To systematically investigate the effects of neural mobilization techniques on muscle strength. Methods: A systematic review performed in Google Scholar databases, Latindex, Lilacs, Pubmed and Scielo, through the descriptors: Muscle Strength, Muscle Contraction, Neural Mobilization and Neurodynamics Mobilization. Transverse and longitudinal controlled studies were included. Studies testing the neural mobilization of the muscle contraction force or humans or animals healthy or to peripheral nerve injury. The selected studies were published between the years 2010 and 2014 in national and international journals with Qualis between B1 and B2 according to an evaluation of the top professional development coordination. Results: The screening process resulted in the identification of 70 studies, of which only five not fit the eligibility criteria. Selected manuscripts indicated acute and chronic effects of neural mobilization on muscle strength in healthy volunteers with peripheral nerve damage by leprosy and rats with sciatic neuropathy. Conclusion: The results of this study indicate positive effects of neural mobilization in relation to the recruitment of muscle fibers, increasing strength and maintaining muscle strength in healthy volunteers and the peripheral nervous system injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
