Chronic wounds affect over 4 million individuals and pose a significant burden to the US healthcare system. Diabetes, venous stasis, radiation or paralysis are common risk factors for chronic wounds. Unfortunately, the current standard of care (SOC) has a high relapse rate and these wounds continue to adversely affect patients' quality of life. Fortunately, advances in tissue engineering have allowed for the development of cell-based wound dressings that promote wound healing by improving cell migration and differentiation. As the available options continue to increase in quantity and quality, physicians should have a user-friendly guide to reference when deciding which dressing to use. The objective of this review is to identify the currently available biologic dressings, describe their indications, and provide a framework for integration into clinical practice. This review included 53 studies consisting of prospective and retrospective cohorts as well as several randomized control trials. Three general categories of cell-based biologic dressings were identified and nine brands were included. Cell-based biologic dressings have shown efficacy in a broad range of scenarios, and studies examining their efficacy have improved our understanding of the pathophysiology of chronic wounds. Amniotic and placental membranes have the widest scope and can be used to treat all subtypes of chronic wounds. Human skin allografts and bioengineered skin substitutes can be used for chronic ulcers but generally require a vascularized wound bed. Autologous platelet rich plasma (PRP) has shown promise in venous stasis ulcers and decubitus ulcers that have failed conventional treatment. Overall, more research is necessary to determine if these novel therapeutic options will change the current SOC, but current studies demonstrate encouraging results in the treatment of chronic wounds.

One of the unsolved mysteries in oncology includes the strategies that cancer cells adopt to cope with an adverse microenvironment. However, we knew, from the Warburg's discovery that through their metabolism based on sugar fermentation, cancer cells acidify their microenvironment and this progressive acidification induces a selective pressure, leading to the development of very malignant cells entirely armed to survive in the hostile microenvironment generated by their own metabolism. In the last decades a primordial role for proton exchangers has been supported as a key tumor advantage in facing off the acidic milieu. Proton exchangers do not allow intracellular acidification through a continuous elimination of H+ either outside the cells or within the internal vacuoles. This article wants to comment a translational process through that led to the preclinical demonstration that a class of proton pump inhibitors (PPI) exploited worldwide for peptic ulcer treatment and gastroprotection are indeed powerful chemosensitizers as well. In this process we achieved the clinical proof of concept that PPI may well be included in new anti-cancer strategies with a solid background and rationale.

Compression therapy is the basis for successful treatment in most patients with venous leg ulcers. Concerning compression therapy, the initial phase of decongestion and the following phase of maintenance should be differentiated. While in the maintenance phase (ulcer) stocking systems are now frequently recommended, in the decongestion phase compression bandages are mostly still used, which however are often inappropriately applied. In German-speaking countries, compression therapy with short-stretch bandages has a long tradition. However, their correct application requires good training and monitoring, which is often lacking in daily practice. Less error-prone treatment alternatives are multicomponent systems, some of which have an optical marker for the control of the correct subbandage pressure. In another new type of compression system, which is called adaptive or wrap bandages, the compression pressure can be adjusted using a Velcro fastener. Accompanying intermittent pneumatic compression therapy can also be used in the decongestion phase. Thus, there are now several different treatment options that can be used for the decongestion phase in patients with venous leg ulcers. Often bandages with short-stretch materials are very prone to errors and should in most cases be replaced by other compression systems today. The patient's preference, need, and capability should be considered when selecting the appropriate system for the individual patient.

Objective: Various treatment options exist for wound healing; however, clinical assessment of the patient and the wound environment must be considered before determining an optimal wound treatment plan. Negative pressure wound therapy alone and/or with an instilled topical solution can be effective in adjunctive management of acute and chronic wounds. Hyperbaric oxygen therapy has also been shown to contribute to the wound-healing process. A pilot evaluation using a multistep approach of adjunctive negative pressure wound therapy with instillation and a dwell time, standard negative pressure wound therapy, and hyperbaric oxygen therapy was explored to manage postsurgical, diabetic lower-extremity wounds with a significant bioburden. Methods: Three diabetic patients with lower-extremity ulcers were treated after surgical intervention. Multistep wound therapy consisted of (1) negative pressure wound therapy with instillation of normal saline with a 20-minute dwell time, followed by 2 hours of negative pressure at -150 mm Hg for 3 to 4 days; (2) 1 to 3 weeks of continuous negative pressure at -150 mm Hg; and (3) multiple treatments of hyperbaric oxygen therapy. Results: After surgery, wound closure was achieved within 4 weeks postinitiation of multistep wound therapy. All patients regained limb function and recovered with no long-term sequelae. Conclusions: In these 3 cases, a multistep wound therapy approach after surgery resulted in successful outcomes; however, larger prospective studies are needed to demonstrate the potential efficacy of this approach in the postsurgical management of complex, diabetic lower-extremity wounds.

Human skin presents a large, easily accessible matrix that is potentially useful for diagnostic applications based on whole body metabolite changes-some of which will be volatile and detected using minimally invasive tools. Unfortunately, identifying skin biomarkers that can be reliably linked to a particular condition is challenging due to a large variability of genetics, dietary intake, and environmental exposures within human populations. This leads to a paucity of clinically validated volatile skin biomarker compounds. Animal models present a very convenient and attractive way to circumvent many of the variability issues. The rabbit (Leporidae) is a potentially logistically useful model to study the skin metabolome, but very limited knowledge of its skin metabolites exists. Here we present the first comprehensive assessment of the volatile fraction of rabbit skin metabolites using polydimethylsiloxane sorbent patch sampling in conjunction with gas chromatography/mass spectrometry. A collection of compounds that are secreted from rabbit skin was documented, and predominantly acyclic long-chain alkyls and alcohols were detected. We then utilized this animal model to study differences between intact skin and skin with early pressure ulcers, as the latter are a major problem in intensive care units. Four New Zealand female white rabbits underwent ulcer formation on one ear with the other ear as a control. Early-stage ulcers were created with neodymium magnets. Histologic analysis showed acute heterophilic dermatitis, edema, and micro-hemorrhage on the ulcerated ears with normal findings on the control ears. The metabolomic analysis revealed subtle but noticeable differences, with several compounds associated with the oxidative stress-related degradation of lipids found to be present in greater abundances in ulcerated ears. The metabolomic findings correlate with histologic evidence of early-stage ulcers. We postulate that the Leporidae model recapitulated the vascular changes associated with ulcer formation. This study illustrates the potential usefulness of the Leporidae model for skin metabolome studies. Additionally, skin metabolome analysis may enhance an understanding of non-skin sources such as urine or breath.

- Standing balance in people with trans-tibial amputation due to vascular causes: A literature review. [Journal Article]
- POProsthet Orthot Int 2017 Jan 01; :309364616683819
- CONCLUSIONS: According to the findings of this review, individuals with trans-tibial amputees due to vascular causes have diminished balance abilities. Limited evidence suggests their balance might be further diminished as compared to individuals with trans-tibial amputation due to trauma. Although the evidence is limited, because of the underlying pathology and presence of comorbidities in individuals with trans-tibial amputation due to vascular causes, one cannot ignore these findings, as even a minor injury from a fall may develop into a non-healing ulcer and affect their health and well-being more severely than individuals with trans-tibial amputation due to trauma. Clinical relevance Individuals with trans-tibial amputation due to vascular causes have diminished balance abilities compared to healthy individuals and individuals with trans-tibial amputation due to trauma. This difference should be considered when designing and fabricating prostheses. Prosthetists and rehabilitation clinicians should consider designing amputation cause-specific rehabilitation interventions, focussing on balance and other functional limitations related to comorbidities of amputation.
