Selective activation of shoulder, trunk, and arm muscles: A comparative analysis of different push-up variants
2015
Context The push-up is a widely used exercise for upper limb strengthening that can be performed with many variants. A comprehensive analysis of muscle activation during the ascendant phase (AP) and descendant phase (DP) in different variants could be useful for trainers and rehabilitators. Objective To obtain information on the effect of different push-up variants on the electromyography (EMG) of a large sample of upper limb muscles and to investigate the role of the trunk and abdomen muscles during the AP and DP. Design Cross-sectional study. Setting University laboratory. Patients or Other Participants Eight healthy, young volunteers without a history of upper extremity or spine injury.…
Trunk muscle activity during different variations of the supine plank exercise.
2017
BACKGROUND: Exercises providing neuromuscular challenges of the spinal muscles are desired for core stability, which is important for workers with heavy manual labour as well as people recovering from back pain.PURPOSE: This study evaluated whether using a suspended modality increases trunk muscle activity during unilateral or bilateral isometric supine planks.DESIGN: Cross-sectional.METHODS: Twenty university students participated in this cross-sectional study. Each subject performed four different conditions: bilateral stable supine plank, unilateral stable supine plank, bilateral suspended supine plank and unilateral suspended supine plank. Surface electromyography (EMG) signals were rec…
Endoscopic subfascial sectioning of incompetent perforating veins in treatment of primary varicosis
1992
Subfascial elimination of incompetent perforating veins is the most effective therapeutic principle in the treatment of trophic skin disorders associated with varicosis. A recently developed endoscopic technique allows accurate sectioning of perforating veins with direct observation of the veins and minor trauma. From November 1986 to July 1991 endoscopic sectioning of perforating veins was performed in 72 patients (103 legs). The most frequently transected perforating veins were Cockett's veins (n = 219), 24 cm perforating veins (n = 83), and Boyd's perforating veins (n = 82). Postoperative delayed wound healing was observed in 3 (2.9%) legs with pronounced trophic skin disorders in the lo…
Midterm Results of the Treatment of Penetrating Abdominal Aortic or Iliac Artery Ulcer with the BeGraft Balloon-Expandable Covered Stent-A Single-Cen…
2020
Background The purpose of the study was to evaluate the feasibility and efficacy of the novel BeGraft covered stent for the treatment of abdominal penetrating aortic ulcer (PAU) or penetrating ulcers of the iliac arteries (PUIAs). Methods This was a single-center observational study, which included 24 consecutive patients who underwent endovascular surgery due to abdominal PAU or PUIA between June 2017 and September 2019. Demographics of patients, lesion characteristics, diameter and length of the BeGraft stents, and postoperative events were prospectively collected and retrospectively analyzed. Follow-up examinations were performed at 1, 6, 12, and 24 months with clinical and hemodynamic e…
Long-term radiation exposure in patients undergoing EVAR: Reflecting clinical day-to-day practice to assess realistic radiation burden.
2018
Endovascular repair of aortic aneurysms (EVAR) has become an established treatment option currently applied in an increasing numbers of patients with aortic aneurysms. Advantages include reduced surgical trauma, procedural time, intensive care unit and hospital lengths of stay, blood loss as well as morbidity and mortality.The optimal imaging modalities in EVAR follow-up as well as the appropriate intervals between these follow-ups remain subject of controversial discussion. Objective of this study was the evaluation of the realistic radiation exposure and risk estimate postop EVAR treatment.Of the follow-ups required according to the surveillance schedule during the first year post-EVAR, o…
Descriptive and follow-up study of patients treated surgically for abdominal aortic aneurysm at tertiary hospitals in Spain.
2019
BACKGROUND The aim of this study was to assess potential variability in the clinical characteristics and treatment of patients undergoing elective surgery for abdominal aortic aneurysm (AAA) across five hospitals in Spain. METHODS Multicenter, retrospective cohort study of patients diagnosed with AAA and treated with open surgical repair (OSR) or endovascular aneurysm repair (EVAR). We evaluated clinical and demographic variables, including comorbidity (Charlson Comorbidity Index [CCI]); anatomic characteristics; surgical risk (ASA Score); aneurysm characteristics; and in-hospital and overall mortality. All patients were followed for three years. RESULTS A total of 186 patients were include…
Multiple periscope and chimney grafts to treat ruptured thoracoabdominal and pararenal aortic aneurysms
2011
Purpose: To report midterm outcomes after urgent endovascular repair of ruptured pararenal or thoracoabdominal aortic aneurysms using multiple periscope and chimney grafts to preserve renovisceral branch perfusion and facilitate aneurysm exclusion. Methods: Nine consecutive men (mean age 72614 years, range 40–88) presenting with ruptured thoracoabdominal (n56), pararenal (n52), or infrarenal (n51) aortic aneurysm underwent urgent endovascular repair with at least 1 periscope graft delivered via a transfemoral access; chimney grafts were installed from an axillary access. In all, 17 periscope and 7 chimney grafts were used to reperfuse 11 renal and 13 visceral arteries in the 9 patients. The…
Variation of serum and urinary neutrophil gelatinase associated lipocalin (NGAL) after strenuous physical exercise.
2012
AbstractStrenuous exercise may trigger acute complications, such as exertional rhabdomyolysis and gastrointestinal complaint. As less is known about the potential renal impairment after long distance running, we assessed creatinine and neutrophil gelatinase associated lipocalin (NGAL) in serum (sNGAL) and urine (uNGAL) before and after an ultramarathon.The study population consisted of 16 trained male athletes who ran a 60 km ultramarathon. Blood and spot urine samples were collected 20 min before and immediately after the run. Creatinine was assessed by Jaffe assay on Beckman Coulter AU5800 and renal function was expressed as estimated glomerular filtration rate (eGFR) by MDRD formula. NGA…
Diagnosis and surgical management of colovesical fistulas due to sigmoid diverticulitis.
2009
Diverticular disease of the colon is the most frequent cause of colovesical fistulas. In this study we evaluated the accuracy of different diagnostic procedures for the detection of colovesical fistula and the clinical outcome in a series of 49 patients who underwent surgery for colovesical fistula due to sigmoid diverticulitis.Between 1982 and 2007, 42 men and 7 women underwent surgery for colovesical fistula due to sigmoid diverticulitis. Preoperative diagnostic procedures included the poppy seed test, abdominopelvic computerized tomography, magnetic resonance tomography of the abdomen, cystogram, retrograde colonic enema, urethrocystoscopy and colonoscopy.All patients had urinary tract i…
The role of obesity and physical activity in non-specific and radiating low back pain: The Young Finns study
2013
Objective To study the effects of obesity, physical activity, and change in physical activity on the incidence of low back pain and explore whether obesity modifies the effects of physical activity. Methods As part of the ongoing Young Finns Study, 1224 subjects aged 24–39 years free from low back pain during the preceding 12 months at baseline in 2001 were included. Obesity was defined based on the body mass index (BMI) and waist circumference, and physical activity was assessed by the metabolic equivalent of task (MET) index in 2001 and 2007. Results Abdominal obesity, defined by an increased waist circumference, was associated with an increased incidence of radiating low back pain (adjus…
