“…This pattern is dominant, and since the myocardial fibers in the apex are dominant in oblique movement, the LS value in the apical segment will be slightly higher than in other segments, which may be related to the apparent advantage of the oblique fiber distribution. The LS of the ventricular septum, anterior wall (or anterior septum), inferior wall, sidewall, and posterior wall of the myocardium showed a decreasing trend (P<0.05), a result similar to those obtained in previous studies (31). The uneven deformation and the gradient change of LS in each ventricular wall, segment, and a layer of the myocardium, as well as the maintenance of the longitudinal strain gradient, are essential for coordinating the overall left ventricular contraction movement and the maintenance of the normal ejection function (32).…”

Background: Hyperbilirubinemia (HBN) can cause myocardial injury in neonates. Advancement in myocardial deformation imaging allows the detection of subclinical changes in myocardial contractility.The present study aimed to evaluate the changes in left ventricular contractility in newborns with hyperbilirubinemia by 2D speckle tracking imaging (STI).Methods: A group of 134 neonates who reached the diagnostic level of HBN as the HBN group was selected. The control group included 56 healthy newborns. The interventricular septum, anterior partition, anterior wall, sidewall, posterior wall, and inferior wall were separated into the basal, middle, and apical segments. In each segment, speckle tracking analysis was performed in the subintimal, middle, and subadventitial myocardium. The overall longitudinal strain of the myocardium in different ventricular walls and segments and global longitudinal strain (GLS) were computed. At the same time, the laboratory results of blood gas analysis, blood routine tests, liver function, and myocardial enzyme spectrum in HBN neonates were collected and correlated with the left ventricular stratified strain parameters.Results: The gradient of the left ventricular GLS had the same characteristics in both groups of newborns.There was a decreasing trend of longitudinal strain (LS) from the intima to the adventitia (i.e., GLSendo > GLSmid > GLSepi). This gradient was also present in stratified LS in each myocardial segment (P<0.001).The LS showed an increasing trend from the basal to the apical segment (P<0.001). The LS of the ventricular septum, anterior wall (or anterior septum), inferior wall, lateral wall, and posterior wall showed a decreasing trend (P<0.001). Stratified strain parameters of the ventricular wall (i.e., the 3-layer myocardium: LSendo-SEPT, LSmid-SEPT, and LSepi-SEPT) were all significantly lower in the HBN group than in the control group (P=0.

“…The low intensity and duration of the training week are effective in these positive changes. This improvement in low-intensity exercises has also been noted in cardiokines (i.e., IL-33, IL-6, IL-18, IL-1β, and follistatin) [ 66 , 67 , 68 ]. However, low-intensity exercise did not seem to have much of an effect on hepatokines and adipokines (i.e., melanoprotein, fetuin-A, leptin, adiponectin, chemrin, resistin, visfatin, omentin, FGF21, ANGPTL4, and follistatin) [ 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 ].…”

The benefits of physical exercise are well-known, but there are still many questions regarding COVID-19. Chow et al.’s 2022 study, titled Exerkines and Disease, showed that a special focus on exerkines can help to better understand the underlying mechanisms of physical exercise and disease. Exerkines are a group of promising molecules that may underlie the beneficial effects of physical exercise in diseases. The idea of exerkines is to understand the effects of physical exercise on diseases better. Exerkines have a high potential for the treatment of diseases and, considering that, there is still no study of the importance of exerkines on the most dangerous disease in the world in recent years, COVID-19. This raises the fundamental question of whether exerkines have the potential to manage COVID-19. Most of the studies focused on the general changes in physical exercise in patients with COVID-19, both during the illness and after discharge from the hospital, and did not investigate the basic differences. A unique look at the management of COVID-19 by exerkines, especially in obese and overweight women who experience high severity of COVID-19 and whose recovery period is long after discharge from the hospital, can help to understand the basic mechanisms. In this review, we explore the potential of exerkines in COVID-19 by practicing physical exercise to provide compelling practice recommendations with new insights.

“…The 2D-STE technique has been used to investigate the LA properties of athletes in most studies. However, it has a strong space and time dependence and easily causes speckle loss of tracking, and the analysis process is complex [ 18 ]. The 4D LAQ is a new method for assessing LA myocardial strain based on the full volumetric imaging, with the advantages of fast, comprehensive and repeatability, which can track the movement trajectory of myocardial spots in real time and quantitatively detect the motion speed and strain of LA myocardial tissue, enabling early detection of myocardial damage in athletes and providing early clinical intervention for treatment [ 6 ].…”

Athletes might suffer from potentially fatal heart disease, which has always been a concern in cardiovascular medicine. The changes in left atrial (LA) size and function are related to the occurrence of arrhythmia. In the present study, four-dimensional automatic quantitation (4D LAQ) was used to explore the changes in LA function of young strength athletes. Eighty professional young strength athletes and sixty healthy young adults matched in age were selected for the study. The LA volumes and strains were automatically analyzed by 4D LAQ. The receiver operating characteristic (ROC) curves were used to evaluate the diagnostic value of strain in athletes' LA function. Pearson correlation analysis was performed to assess the potential association between conventional echocardiographic indexes and 4D parameters related to athletes' LA function. Compared to the control group, LA longitudinal and circumferential strain in the athlete group decreased, while LA volume increased (P < 0.05). However, LA strain was similar among 45 male and 35 female strength athletes (P > 0.05), while male athletes presented with a higher LA volume when compared to female controls (P < 0.05). ROC curve analysis showed that LA contraction longitudinal strain (LASct) was the best predictor in evaluating athletes' LA function. Athletes' heart rate and left ventricular mass index were significantly correlated with 4D LA function parameters.4D LAQ can be used for early detection of the changes in LA function in young strength athletes. There was no significant difference in LA strain between male and female athletes. The LASct was the most effective index for evaluating athletes' LA function.
