Question 1Prominent R wave in V1 may be seen in:AAnterior wall myocardial infarctionBInferior wall myocardial infarctionCLeft bundle branch blockDPosterior wall myocardial infarctionQuestion 1 Explanation:  In posterior wall infarction, the prominent R wave in V1 is the mirror image of Q wave which would have been detected in posterior leads. Prominent R in V1 can occur in anterior wall myocardial infarction complicated by right bundle branch block (QR pattern). In usual anterior wall infarction, the r wave in V1 is knocked off. Question 2Cob-web sign on cardiac CT scan is seen in:AAortic regurgitation BAortic dissectionCAortoarteritisDAortic stenosis Question 2 Explanation:  Cob-web sign in aortic dissection are slende...

Conclusion Swim training, a sport characterized by unique cardiac loading conditions, stimulates eccentric LV remodeling with the concomitant augmentation of systolic twist and diastolic relaxation. This volume-mediated cardiac remodeling appears to result in greater systolic susceptibility to acute afterload challenge. Further work is required to establish how training-induced changes in function translate to human performance and whether these are accompanied by physiologic trade-offs with relevance to common forms of heart disease.

Conclusions Lifelong physical activity volumes are not associated with genotype-to-phenotype transition in HCM gene carriers. We also found no difference in LV wall thickness across physical activity tertiles. However, the most active HCM patients were younger at the time of diagnosis and had a higher arrhythmic burden. These observations warrant further exploration of the role of exercise in HCM disease development.

Conclusion Our study provides novel evidence that EXE-induced antisenescence against metabolic distress in the hippocampus may be a key neuroprotective mechanism, preventing neuroinflammation and oxidative stress.

Conclusions The increase in HR rather than an increase in CBF or forearm venous volume was responsible for the decrease in SV during moderate-intensity exercise when Tsk was held at 38°C.

Conclusions After accounting for baseline PA, greater positive changes in leisure-time PA levels were associated with a more eccentric-type of LV remodeling pattern over 10 yr. The clinical implications of such findings remain to be determined.

Conclusions This indicates that dermal Ca loss was not the primary trigger for the increases in PTH and CTX during exercise. Further research is necessary to understand the causes and consequences of the disruption in Ca homeostasis during exercise and specifically the extravascular shift in iCa.

Purpose Low-attenuation muscle (LAM) area at mid-thigh, a computed tomography (CT)–derived index of intramuscular lipids, is associated with insulin resistance, obesity, and type 2 diabetes. The present study aimed at testing the hypothesis that changes in LAM area in trunk muscles from a single abdominal scan could provide relevant information to evaluate the effects of a lifestyle intervention without the use of a mid-thigh CT scan. Methods Cardiometabolic risk variables, including waist circumference, lipoprotein–lipid profile, glucose tolerance, and cardiorespiratory fitness, were assessed in a sample ...

Conclusion Although TVS is useful for screening for induction failure, this tool should not be used as an indication for cesarean section.Resumo Objetivo Nem sempre a indu ção do parto termina emparto vaginal, expondo tanto a mãe quanto o feto aos riscos inerentes ao procedimento de indução, ou a uma possível cesárea. A ultrassonografia transvaginal (UTV) semostrou interessante instrumento na predição da prematuridade e, neste estudo, utilizamos este instrume nto na situação inversa: indução do parto no pós-datismo. Mét...
