Traditional negative pressure wound therapy (NPWT) has revolutionized the treatment of complex wounds for nearly 20 years. A decade ago, a modification of the original system added intermittent automated instillation of topical wound irrigation solutions to traditional negative pressure wound therapy. This combined therapy, termed negative pressure wound therapy with ...

The evolution of wound care has seen much technological advancement over many decades. Most recently, negative-pressure therapy, by which a vacuum pressure is applied through a wound bed, has dramatically improved the surgical outcomes of complex wounds. Although initial studies focused on wounds to the abdomen, torso, and extremities, more ...

Biofilms are communities of microbes that exist in a variety of environments. The extracellular substances secreted by biofilms make them difficult to eradicate, giving the bacterial community in the biofilm a resistance advantage over freefloating (planktonic) microbes. Biofilms are particularly problematic in chronic wounds because of their resistance to conventional ...

Objective Topical application of subatmospheric pressure (TASAP) promotes faster wound healing, but tissue effects are not entirely understood. This study investigated microvascular effects of TASAP in striated muscle with the hypothesis being that TASAP elicits arteriolar vasodilation and decreases interstitial accumulation of protein.Methods Rat cremasteric microcirculation was directly examined in two experiments ...

Several researches have shown that negative-pressure wound dressings can secure split-thickness skin grafts and improve graft survival. However, in anatomically difficult body regions such as the perineum it is questionable whether these dressings have similar beneficial effects. In this study, we evaluated the effects of negative-pressure wound dressings on split-thickness ...

During early demersal ontogeny, many marine fishes display complex habitat-use patterns. Grunts of the speciose genus Haemulon are among the most abundant fishes on western North Atlantic coral reefs, with most species settling to shallow habitats (≤12 m). To gain understanding into cross-shelf distributional patterns exhibited by newly settled stages ...

Aim  Quantification of the anorectal reflex function is critical for explaining the physiological control of continence. Reflex external anal sphincter activity increases with rectal distension in a dynamic response. We hypothesized that rectal distension would similarly augment voluntary external anal sphincter function, quantified by measuring the anal maximum squeeze pressure. ...

Chronically elevated plasma angiotensin II (AngII) causes a salt-sensitive form of hypertension that is associated with a differential pattern of peripheral sympathetic outflow. This "AngII-salt sympathetic signature" is characterized by a transient reduction in sympathetic nervous system activity (SNA) to the kidneys, no change in SNA to skeletal muscle, and ...

Hypertension is a significant risk factor for cardiovascular morbidity and mortality in people older than 60 years. Isolated systolic hypertension and widened pulse pressure appear to be more important than diastolic hypertension. Very low blood pressure and orthostatic hypotension are associated with increased mortality, and should be checked for at every ...
