“…The results led to two main findings: first, we observed that both regimens of CT elicited favorable effects on the LA Correlation between the changes in the systolic blood pressure and in PALS in patients undergoing supervised exercise (CTLF + CTHF). (29). Conversely, no changes or small reductions in reservoir strain were described in athletes (30,31).…”

“…Regarding the first point, the LA adaptations to exercise training have been assessed mainly in healthy subjects and athletes, while very few studies on this topic have previously been conducted in patients with cardiovascular diseases. In sedentary healthy individuals, increases in the LA strain parameters have been observed after short exercise training interventions without any detectable change in the LA size ( 29 ). Conversely, no changes or small reductions in reservoir strain were described in athletes ( 30 , 31 ).…”

PurposeLeft atrial dysfunction has shown to play a prognostic role in patients with ischemic cardiomyopathy (ICM) and is becoming a therapeutic target for pharmacological and non-pharmacological interventions. The effects of exercise training on the atrial function in patients with ICM have been poorly investigated. In the present study, we assessed the effects of a 12-week combined training (CT) program on the left atrial function in patients with ICM.MethodsWe enlisted a total of 45 clinically stable patients and randomly assigned them to one of the following three groups: 15 to a supervised CT with low-frequency sessions (twice per week) (CTLF); 15 to a supervised CT with high-frequency sessions (thrice per week) (CTHF); and 15 to a control group following contemporary preventive exercise guidelines at home. At baseline and 12 weeks, all patients underwent a symptom-limited exercise test and echocardiography. The training included aerobic continuous exercise and resistance exercise. The analysis of variance (ANOVA) was used to compare within- and inter-group changes.ResultsAt 12 weeks, the CTLF and CTHF groups showed a similar increase in the duration of the ergometric test compared with the control (ANOVA p < 0.001). The peak atrial longitudinal strain significantly increased in the CTHF group, while it was unchanged in the CTLF and control groups (ANOVA p = 0.003). The peak atrial contraction strain presented a significant improvement in the CTHF group compared with the CTLF and control groups. The left ventricular global longitudinal strain significantly increased in both the CTHF and the CTLF groups compared with the control group (ANOVA p = 0.017). The systolic blood pressure decreased in the CTHF and CTLF groups, while it was unchanged in the control group. There were no side effects causing the discontinuation of the training.ConclusionsWe demonstrated that a CT program effectively improved atrial function in patients with ICM in a dose–effect manner. This result can help with programming exercise training in this population.

“…Their training protocol consisted of running and walking on a treadmill, which was one of the limitations of their study in that HIIT and CMT had not been offered under isocaloric conditions. The training intensity during the 16-week period should be controlled by determining VO 2 max and the maximum heart rate to apply an accurate intensity and allow its efficiency to be examined through retest [ 29 ]. In addition, the training intensity in the study from Scharf et al was greater than that of the present research (calculated based on the maximum heart rate).…”

The present study aimed to identify changes in echocardiographic parameters before and after three-month high-intensity interval training (HIIT) and continuous moderate-intensity training (CMT) in male employees. For this purpose, using a convenience sampling method, 33 male employees of the Islamic Republic of Iran Army (office workers with a sedentary lifestyle) aged 30 through 40 were selected. Participants were divided into three groups of HIIT, CMT, and control (11 for each group) including all anthropometric data (body fat percentage, body mass index, height, weight, and VO2 max) with no history of chronic diseases, metabolic syndrome, confirmed heart disease or congenital heart defect, and hospitalization due to chronic diseases or consumption of medication affecting cardiovascular indicators. A one-way ANOVA was conducted to compare the groups. The results demonstrated that the end-systolic volumes (ESVs) (p < 0.01) and relative wall thickness (RWT) in the CMT group (p < 0.01) and the end-diastolic volumes (EDVs) (p < 0.01), stroke volumes (SVs) (p < 0.01), end-systolic and diastolic diameters (ESD, EDD) (p < 0.01), as well as the RWT and left ventricle diastolic function (E/A ratio) in the HIIT group (p < 0.05) were significantly different before and after the 12-week training (Bonferroni correction was used for pairwise comparisons). The results revealed a significant increase in the end-systolic diameters (ESDs) of the HIIT group, whereas no such increase was observed in the ESDs of the CMT group (p < 0.51). Moreover, a significant increase was observed in left ventricular (LV) RWT and aerobic power of both training groups. The significant decrease of ESVs and the significant increase in E/A ratio, ESDs, EDDs following HIIT (two to three sessions per week) may indicate beneficial and optimal LV structural adaptations and improved LV function in nonathletes (even with a sedentary lifestyle).

“…As the teleoperated systems permeate surgery, they showcase numerous benefits compared to traditional methods [46,47]. As a result, many procedures have been converted from laparoscopic surgery to RAMIS, from cancer removal to partial organ resection [48,49,50,51,52,53,54,55,56,57,58,59,60]. As it emerges from all these studies, RAMIS represents a significant upgrade to laparoscopic surgery.…”

Teleoperated robots have been widely accepted in several fields of medical practice, enhancing human abilities and allowing remote operation. However, such technology has not been able yet to permeate areas such as primary care and physical examination. Such applications strongly rely on the quality of the interaction between doctor and patient, and on its multimodal nature. In order to achieve remote physical examination is thus mandatory to have a good doctor-robot interface, but what does good mean? Ultimately, the goal is for the user to achieve task embodiment, making the remote task feel like the in-person one. Several research groups have proposed a wide variety of interfaces, showcasing largely different methods of control and feedback, because of the absence of design guidelines. In this work, we argue that the ideal interface for a remote task should resemble as close as possible the experience provided by the in-person equivalent, keeping in consideration the nature of the target users. To support our claims, we analyze many remote interfaces and compare them with the respective in-person task. This analysis is not limited to the medical sector, with examples such as remote abdominal surgery, but it expands to all forms of teleoperation, up to nuclear waste handling and avionics.
