previous studies have demonstrated that regular avocado consumption presents advantageous effects on cardiovascular system. However, little attention has been paid to the use of avocado as a dietary supplement, in particular, for individuals involved in physical exercise training. therefore, this study aims to evaluate the effect of acute avocado pulp intake on cardiovascular and autonomic recovery subsequent to moderate exercise. Using a crossover, randomized, double-blind and placebocontrolled trial design, 16 healthy female adults underwent two protocols: Avocado pulp (600 mg in capsule) and placebo (600 mg starch in capsule). After the ingestion of Avocado pulp or placebo, the subjects were seated for 60 min at rest, followed by running on a treadmill at a submaximal level and then remained seated for 60 min during recovery from the exercise. Heart rate (HR), heart rate variability (HRV) [rMSSD, SD1, HF (ms 2)] and skin conductance were evaluated before and during exercise, as well as during recovery. HR, systolic blood pressure, HRV and skin conductance recovered faster when subjects were given avocado pulp prior to exercise. in conclusion, avocado pulp improved cardiovascular and autonomic recovery after exercise, suggesting a reduced risk of cardiovascular events after exertion. The current results support the beneficial effects of ingestion of avocado prior to submaximal treadmill running. The autonomic nervous system is controlled by central areas in the brain and brainstem 1,2. During exercise the autonomic nervous system is responsible for physiological changes required to meet the contending demands of skin blood flow (thermoregulation) and the functioning muscles (metabolic loads), to maintain blood pressure and optimal organ perfusion 1. This is key to keeping the body healthy under stressful conditions 1,2. In the first few seconds of exercise, reduction of parasympathetic activity increases heart rate (HR), followed by an elevation
A agenesia de artéria pulmonar é uma malformação congênita rara, que ocorre devido ao não desenvolvimento do sexto arco aórtico. Entretanto, não é relacionada com malformações cardíacas. Além de as artérias intrapulmonares, a vascularização pulmonar e a árvore brônquica geralmente não sofrerem alterações. No presente relato, a paciente apresenta quadro de febre, tosse produtiva e taquipneia. Devido à clínica, optou-se por realizar radiografia simples de tórax, na qual se evidenciou a presença de opacidade interstício-alveolar peri-hilar à direita com desvio do mediastino à direita e assimetria da transparência pulmonar. Então, foi solicitada tomografia computadorizada de tórax que evidenciou pulmão direito de volume reduzido. Para melhor compreensão, realizou-se angiotomografia computadorizada do tórax, a qual detectou agenesia da artéria pulmonar direita. Importância do problema: relatar um caso de agenesia de artéria pulmonar direita.
Objective: a perceptive assessment of the aid provided by magnetic resonance image (MRI) of the fetus to ultrasonography (US) in diagnosing and prognosing dependably diaphragmatic hernias. Methods: 13 pregnant women with gestation period ranging from 20 to 32 weeks underwent diagnostic test to performed by a GE scanner (General Electric) Logic 500 and Voluson 730 with transducers of 3.5 and 5.0 MHz and volumetric (3D and 4D). The MRI tests were performed by a 1.5 Tesla (Siemens and General Electric) with HASTE and SSFSE sequences. Results: 11 fetuses showed left diaphragmatic hernia (LDH), and 2 fetuses showed right diaphragmatic hernia (RDH). The fetal liver was localized through ultrasound scan within the thorax of 4 fetuses (2 with LDH and 2 with RDH). MRI could, nevertheless, detect 7 fetuses with the same problem (5 with LDH and 2 with RDH), what was postnatally confirmed. Ultrasonography could better assess, if compared with magnetic resonance, the face of one of the fetuses with RDH that showed microphthalmia and intraventricular shunt. Another fetus showed, besides LDH, hypoplasia of vermis cerebelli, which was detected by both ultrasonography and magnetic resonance, having trisomy 18. 7 fetuses managed to survive the surgery (6 with LDH and 1 with RDH).
Conclusions:We believe that ultrasonography and MRI are complementary imaging methods in the assessment of diaphragmatic hernias. MRI can definitely add a great deal to US when assessing liver localization; it is therefore an important prognostic factor.
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.
