Article Abstract
Purpose: The aim of this study was to investigate physiological responses and energetic contributions during simulated epée matches in elite fencers.
Methods: Ten elite male fencers participated in simulated epée (direct elimination) matches. Simulated epée matches included 3 bouts of 3 minutes each with 1-minute rests between bouts. During these sessions, physiological variables such as mean and peak heart rate, peak and mean oxygen uptake (VO2peak and VO2mean), metabolic equivalents of task in VO2peak and VO2mean, and blood lactate concentrations (peak lactate concentration and delta blood lactate concentration) were measured. Furthermore, energetic contributions (oxidative [WOxi], glycolytic, and phosphagen) and time-motion variables were estimated.
Results: Values of peak heart rate, mean heart rate, and WOxi (in percentages) were significantly higher in the second and third bouts compared with the first. VO2peak and metabolic equivalents of task in VO2peak were significantly higher in the first bout compared with the third bout. Values of delta blood lactate concentration and glycolytic contribution (in kilojoules and percentages) were significantly lower in the second and third bouts compared with the first. VO2mean and metabolic equivalents of task in VO2mean were significantly higher in the second bout compared with the third bout. Furthermore, WOxi (in kilojoules and percentage) was significantly higher in all bouts compared with phosphagen and glycolytic contributions. Low positive and negative correlations were seen between WOxi, VO2mean, sum of attacks and defense times, and the sum of time without attacks and defenses.
Conclusions: Direct-elimination epée matches consist of high-intensity intermittent exercise, and the oxidative contribution is 80% to 90%. Improving aerobic conditioning may support high-intensity intermittent actions during entire epée matches in elite fencers.

Background: This study aimed to evaluate the impact of asthma severity on biventricular cardiac functions using tissue Doppler imaging (TDI), two-dimensional speckle tracking echocardiography (2D-STE), and three-dimensional speckle tracking echocardiography (3D-STE).
Methods: Sixty-three children with asthma, aged between 5 and 16 years, were enrolled in the study along with 63 matched controls. All participants underwent cardiac assessments, including TDI, 2D-STE, 3D-STE, conventional echocardiography, and pulmonary function testing with spirometry.

Department of Otolaryngology, Masih Daneshvari Hospital, Neyavran, Darabad, Tehran, Iran.
Nasal alar reconstruction is complex due to the region's anatomy and aesthetic importance. This report describes repairing a small, full-thickness alar rim defect in a 36-year-old man using a rotational columellar skin flap with septal cartilage grafting. This single-stage technique achieved good color match, symmetry, and minimal donor-site morbidity.

Background And Aims: This study aimed to describe Crohn's disease perianal fistulizing lesions in patients undergoing surgery over 60 years to compare clinical presentation, management and outcomes with those observed in younger patients.
Methods: Between January 2012 and December 2022, all patients over 60 years old who underwent a first surgical intervention for anal fistula at two medical centers were included. For each patient included, two younger patients who underwent the same surgical procedure during the same period in the same centers were matched for comparison.
Mild cognitive impairment impacts association of functional brain connectivity with cognition in older adults with and without multiple sclerosis.

Department of Neurology, Albert Einstein College of Medicine, Bronx, NY, USA.
Cognitive decline is common in multiple sclerosis (MS), although neural mechanisms are not fully understood. The objective was to investigate the impact of mild cognitive impairment (MCI) on the relationship between resting state functional connectivity (RSFC) and cognitive function in older adults with multiple sclerosis (OAMS) and age matched healthy controls. Participants underwent magnetic resonance imaging (MRI) scans and cognitive assessments.
