0126: New regulators of iron metabolism, Hepcidin and Erythroferrone, in acute myocardial infarction.

2016

Background Dysfunctional iron storage and transport are common in patients with chronic heart failure and associated with poor prognosis. Body iron could contribute to the pathogenesis of coronary artery disease (CAD) through its ability to induce oxidative stress. However, studies on the relationship between iron metabolism and CAD have yielded conflicting results. Patients and Methods From the obseRvatoire des Infarctus de Cote d’Or (RICO) survey, 31 consecutive patients admitted in Intensive Care Unit for a first AMI were included. Serum concentrations of iron, transferrin, ferritin, the iron-regulatory hormone hepcidin and erythroferrone (a new hepcidin-regulating hormone), transferrin …

Treatment with human umbilical cord-derived mesenchymal stem cells for COVID-19 patients with lung damage: a randomised, double-blind, placebo-contro…

2020

AbstractBACKGROUNDTreatment of severe Corona Virus Disease 2019 (COVID-19) is challenging. We performed a phase 2 trial to assess the efficacy and safety of human umbilical cord-mesenchymal stem cells (UC-MSCs) to treat severe COVID-19 patients with lung damage, based on our phase 1 data.METHODSIn this randomized, double-blind, and placebo-controlled trial, we recruited 101 severe COVID-19 patients with lung damage. They were randomly assigned to receive either UC-MSCs (4 × 107 cells per infusion) or placebo on day 0, 3, and 6. The primary endpoint was an altered proportion of whole lung lesion volumes from baseline to day 28. Other imaging outcomes, 6-minute walk test, maximum vital capaci…

Resistance Training with Single vs. Multi-joint Exercises at Equal Total Load Volume: Effects on Body Composition, Cardiorespiratory Fitness, and Mus…

2017

The present study aimed to compare the effects of equal-volume resistance training performed with single-joint (SJ) or multi-joint exercises (MJ) on VO2max, muscle strength and body composition in physically active males. Thirty-six participants were divided in two groups: SJ group (n = 18, 182.1 ± 5.2, 80.03 ± 2.78 kg, 23.5 ± 2.7 years) exercised with only SJ exercises (e.g., dumbbell fly, knee extension, etc.) and MJ group (n = 18, 185.3 ± 3.6 cm, 80.69 ± 2.98 kg, 25.5 ± 3.8 years) with only MJ exercises (e.g., bench press, squat, etc.). The total work volume (repetitions × sets × load) was equated between groups. Training was performed three times a week for 8 weeks. Before and after the…

Physical training considerations for optimizing performance in essential military tasks.

2021

Physically demanding essential military tasks include load carriage, manual material handling and casualty evacuation. This narrative review characterizes the main physical attributes related to performance of these occupational tasks and reviews physical training intervention studies in military settings to improve performance in these military tasks. Load carriage performance requires both aerobic and neuromuscular fitness with greater emphasis on maximal strength and absolute maximal oxygen uptake, especially when carrying heavier loads. In manual material handling, maximal strength and power are strongly associated with discrete lifting, while muscular strength, muscular endurance and a…

Evaluation of implementing a community-based exercise intervention during pregnancy

2017

Abstract Objective to evaluate the implementation of a community-based exercise intervention (the Norwegian Fit for Delivery study) during pregnancy. Design descriptive, explorative. Setting healthcare clinics in southern Norway, including urban and rural settings. Participants healthy, nulliparous women with singleton pregnancy of ≤20 gestational weeks, age ≥18 years and body mass index ≥19kg/m 2 . Methods women were randomised to either twice-weekly supervised exercise sessions combined with nutritional counselling ( n =303) or standard prenatal care ( n =303). The exercise program was based on ACOG guidelines, with the same low-impact workout for all participants, including 60minutes of …

Do Running and Strength Exercises Reduce Daily Muscle Inactivity Time?

2016

Understanding how a specific exercise changes daily activity patterns is important when designing physical activity interventions. We examined the effects of strength and interval running exercise sessions on daily activity patterns using recordings of quadriceps and hamstring muscle electromyographic (EMG) activity and inactivity. Five male and five female subjects taking part in a 10-week training programme containing both strength and interval running training sessions were measured for daily muscle EMG activities during three days: on a strength day, an interval running day, and a day without exercise. EMG was measured using textile electrodes embedded into sport shorts that were worn 9…

Effects of combined endurance and strength training on muscle strength, power and hypertrophy in 40-67-year-old men

2009

Both strength and endurance training have several positive effects on aging muscle and physical performance of middle-aged and older adults, but their combination may compromise optimal adaptation. This study examined the possible interference of combined strength and endurance training on neuromuscular performance and skeletal muscle hypertrophy in previously untrained 40-67-year-old men. Maximal strength and muscle activation in the upper and lower extremities, maximal concentric power, aerobic capacity and muscle fiber size and distribution in the vastus lateralis muscle were measured before and after a 21-week training period. Ninety-six men [mean age 56 (SD 7) years] completed high-int…

Differentialdiagnose Berylliose/Sarkoidose bei einem Zahntechniker

2008

History and clinical findings Sarcoidosis was diagnosed in a dental technician when he was aged 21 years. Two years later prednisolone treatment was started and continued for 14 years because of nonproductive cough with progressive reduction in vital capacity and CO transfer capacity. Subsequently the risk of exposure to beryllium-containing dust in dental laboratories became known. In his case exposure had started before sarcoidosis had been diagnosed and had continued for 16 years. Changes typical of sarcoidosis (unproductive cough and dyspnoea; bihilar lymphadenopathy and reticulonodular marking in the chest radiogram) were now present, at the age of 40 years. Investigations Vital and di…
