Challenges in stability control are common post-stroke. Although lower-limb spasticity is a common sensorimotor consequence post-stroke, its potential to further complicate stability control among stroke-survivors remains largely unknown. Advancing such understanding can help inform strategies to reduce fall risk and increase independence among these individuals. The purpose of this study ...

Copperhead envenomation causes local soft tissue effects; however, associated compartment syndrome is rare. We report a case of a 17-month-old with significantly elevated compartment pressures successfully treated with antivenin and supportive care. A 17-month-old girl sustained a copperhead bite to the foot and presented with circumferential edema, erythema, and ecchymosis ...

Fresh human cadavers provide an effective model for procedural training. Currently, there are no realistic models to teach fascial compartment pressure measurement. We created a human cadaver fascial compartment pressure measurement model and studied its feasibility with a pre-post design. Three faculty members, following instructions from a common procedure textbook, ...

Abstract Objective. We sought to compare the flow rates of the proximal tibia, the distal femur, and the proximal humerus using high pressure (greater than 300 mmHg) through an intraosseous (IO) infusion needle in an adult swine model. Methods. We performed a prospective interventional study in 11 swine. After placement of ...

BACKGROUND: Osseofascial compartment syndrome is defined by ischemic necrosis of muscle caused by elevated pressure within fascial compartments. The diagnosis can be made either clinically or through compartment pressure measurements. Compartment pressure above 30 mm Hg was traditionally used as the threshold for diagnosis of compartment syndrome, but was challenged ...

Internal stress in a compression bandage wrapped over a limb in vitro is expected to reduce over time because of fatigue which may occur due to repetitive and prolonged variations in the extension of the bandage during posture change and exercise. This phenomenon may cause significant variation in the sub-bandage ...

Fluctuating asymmetry (FA), as an indirect measure of developmental instability (DI), has been intensively studied for associations with stress and fitness. Patterns, however, appear heterogeneous and the underlying causes remain largely unknown. One aspect that has received relatively little attention in the literature is the consequence of direct mechanical effects ...

Acute compartment syndrome occurs when the tissue pressure within a closed muscle compartment exceeds the perfusion pressure. We observed diastolic retrograde arterial flow (DRAF) in 2 patients in the arteries proximal to compartment syndromes in injured limbs. We hypothesized that DRAF may represent an early sign of compartment pressure increments. ...

BACKGROUND: /st>Aortocaval compression (ACC) can result in haemodynamic disturbances and uteroplacental hypoperfusion in parturients. Its detection is difficult because in most patients, sympathetic compensation results in no signs or symptoms. However, profound hypotension may develop after sympathectomy during regional anaesthesia. In this prospective observational study, we aimed to detect ACC ...

Many trans-tibial amputees could not tolerate long-distance walking. Lack of walking could explain for the increased cardiovascular diseases mortality rate. This study investigated the effects of long-distance walking (LDW) on socket-limb interface pressure, tactile sensitivity of the residual limb, and subjective feedbacks, which potentially identified the difficulties in LDW. Five ...

Idiopathic lymphedema is a condition where lymph accumulates in subcutaneous tissue without a clear cause. Likewise, idiopathic portal hypertension is a syndrome where intrahepatic peripheral portal branch obstruction causes portal hypertension without a clear cause. We encountered a 37-year-old man with both idiopathic lymphedema and idiopathic portal hypertension. He had ...

Vascular dysfunction, including reduced endothelium-dependent dilation, is a major characteristic of hypertension. We previously investigated that thioredoxin reductase (TrxR) inhibition impairs vasodilation via soluble guanylyl cyclase S-nitrosylation, but S-nitrosylation and TrxR function are not known in hypertension. We hypothesized that S-nitrosylation is associated with reduced vasodilation in hypertensive mice. Aortic ...

Nitric oxide (NO), produced by endothelial nitric oxide synthase (eNOS), is a potent vasodilator and plays a prominent role in regulating the cardiovascular system. Decreased basal NO release may predispose to cardiovascular diseases. Evidence suggests that the 27nt repeat polymorphism of the intron 4 in the eNOS gene may regulate ...

Left ventricular hypertrophy (LVH) is a cardiovascular complication highly prevalent in patients with chronic kidney disease (CKD) and end-stage renal disease. LVH in CKD patients has generally a negative prognostic value, because it represents an independent risk factor for the development of arrhythmias, sudden death, heart failure and ischemic heart ...

Clinical relevance of a genetic predisposition to elevated blood pressure was quantified during the transition from childhood to adulthood in a population-based Finnish cohort (N=2357). Blood pressure was measured at baseline in 1980 (age 3-18 years) and in follow-ups in 1983, 1986, 2001, and 2007. Thirteen single nucleotide polymorphisms associated ...
