Objective: The aim of this study was to evaluate the efficiency of a short-term Intermittent Work Exercise Program (IWEP) among healthy elderly subjects.
Study Design And Setting: This longitudinal prospective study took place at the Strasbourg University Hospital geriatric department.
Study Participants: One hundred and fifty older volunteers, previously determined as being free from cardiac and pulmonary disease, were separated into two age groups: the "young senior" (60.2 ± 3.1 yr) and the "older senior" groups (70.8 ± 5.2 yr). These groups were then subdivided by gender into the "young female senior", "young male senior" "older female senior" and "older male senior" groups.
Intervention: Before and after the IWEP, all subjects were asked to perform an incremental cycle exercise to obtain their first ventilatory threshold (VT1), maximal tolerated power (MTP), peak oxygen uptake (VO2peak) and maximal minute ventilation (MMV). The IWEP consisted of a 30-min cycling exercise which took place twice a week, and was divided into six 5-min stages consisting of 4 min at VT1 intensity and 1 min at 90% MTP.
Measurements: An assessment was made of the effects of the IWEP on maximal cardio-respiratory function (MTP, VO2peak, MMV) and endurance parameters (VT1, heart rate [HR] measured at pretraining VT1 and lactate concentrations at pre-training MTP).
Results: This short-term training program resulted in a significant increase of MTP (from 13.2% to 20.6%), VO2peak (from 8.9% to 16.6%) and MMV (from 11.1% to 21.8%) in all groups (p<0.05). VT1 improved from 21% at pretraining to 27%, while HR at pre-training VT1 as well as lactate concentrations at pre-training MTP decreased significantly in all groups (p<0.05). The post-training values for VO2peak and MMV of the "older seniors" were not significantly different (p>0.05) from the "young seniors" pre-training values for the same parameters.
Conclusion: The most striking finding in this study is that after only 9 weeks, our short-term "individually-tailored" IWEP significantly improved both maximal cardio-respiratory function and endurance parameters in healthy, previously untrained seniors.

Objectives: In April 2022, the Society for Vascular Surgery (SVS) published the Appropriate Use Criteria (AUC) for the management of intermittent claudication (IC). Our goal was to compare practice patterns before and after publication of the AUC to identify changes.
Methods: The Vascular Quality Initiative (VQI) peripheral vascular intervention (PVI), and suprainguinal, and infrainguinal bypass registries were analyzed for interventions for IC.
The effect of Constraint-induced movement therapy (CIMT) or Intermittent theta-burst stimulation (iTBS) alone is limited in improving motor function after a stroke. In this study, we explored the efficacy and possible mechanisms in combination of CIMT and iTBS through behavioral evaluation, RNA sequencing, Golgi staining, transmission electronic microscope (TEM), high-performance liquid chromatography (HPLC), western blotting (WB) and immunofluorescence. Firstly, we observed that combination therapy is safe and effective, and it can significantly reduce the number of immature dendritic spines and increase the number of functional dendritic spines, the amount of glutamate (Glu) and the expression of Glu1 receptor (Glu1R).

Meckel's diverticulum (MD) is a common congenital anomaly of the gastrointestinal tract, present in approximately 2% of the population. While typically asymptomatic, MD can lead to complications such as obstruction and intussusception. Here, we present a case report of a man presenting with abdominal pain with an incidental finding of MD complicated by intussusception and our management approach.

Purpose: To determine the incidence of therapeutic target attainment using a three-times per week protocol for vancomycin therapy given during the last hour of intermittent hemodialysis (HD).
Methods: A single-center retrospective cohort study was conducted of patient medical records in a remote dialysis center from January 2017 to July 2023. Adult patients with chronic kidney disease stage 5 on ≥3 months of intermittent HD who had received a course of vancomycin therapy with ≥1 serum vancomycin concentration recorded were included.
