PURPOSE: To evaluate the association of preoperative intra-articular hip injection with surgical site infection after hip arthroscopy. METHODS: A large administrative database was used to identify all patients undergoing hip arthroscopy from 2007 to 2015 within a single private insurer and from 2005 to 2012 within Medicare in the United States. Those that received an ipsilateral preoperative intra-articular hip injection were identified. The patients were then divided into the following groups based on the interval between preoperative injection and ipsilateral hip arthroscopy: (1) <3 months, (2) 3 to 6 months, and (3) 6 to 12 months...

Low-dose radiation has been used in clinical and experimental models for the prevention of scarring and for fracture healing. There is evidence that low-dose radiation improves the hormesis of various cell types but little is known about its effects on peripheral nerve tissue. In this study, we investigated the beneficial effects of low-dose radiation on the regeneration of transectional peripheral nerve injury in an experimental rat model. Seventy-two male Sprague-Dawley rats received transection injury to the left sciatic nerves, and the nerves were subsequently sutured by epineurium end-to-end anastomosis to restore continuity...

Survival improvement in rectal cancer treated with neoadjuvant chemoradiotherapy (nCRT) is achieved only if pathological response occurs. Mandard tumor regression grade (TRG) proved to be a valid system to measure nCRT response. The ability to predict tumor response before treatment may significantly have impact the selection of patients for nCRT in rectal cancer. The aim is to identify potential predictive pretreatment factors for Mandard response and build a clinical predictive model design. 167 patients with locally advanced rectal cancer were treated with nCRT and curative surgery...

Palliative care demonstrably improves quality of life for the seriously ill in a manner that averts preventable health crises and their associated costs. Because of these outcomes, palliative care is now broadening its reach beyond hospitals, and hospice care for those near death, to patients and their families living in the community with chronic multimorbidities that have uncertain or long expected survival. In this article, we address research needed to enable policies supportive of palliative care access and quality, including changes in regulatory, accreditation, financing, and training approaches in the purview of policy makers...

BACKGROUND: Neovascularization is impaired in diabetes mellitus, which leads to the development of peripheral arterial disease and is mainly attributed to the dysfunction of endothelial progenitor cells (EPCs). Previous studies proved the promotional effect of curcumin on neovascularization in wound healing of diabetes. Thus, we hypothesize that curcumin could promote neovascularization at sites of hindlimb ischemia in diabetes and might take effect via modulating the function of EPCs...

BACKGROUND AND AIMS: Limited data exist on the association of the anatomical distribution of atherosclerotic lesions and the extent of atherosclerosis at defined arterial segments with life expectancy. We recently presented a new classification of the extent of atherosclerosis in crural vessels and showed that Crural Index (CIx) was associated with mid-term survival of symptomatic peripheral artery disease (PAD) patients. This study evaluates the significance of the extent of crural atherosclerosis on long-term cardiovascular mortality...

BACKGROUND: A variety of devices exist for endovascular aneurysm repair (EVAR). Device-specific instructions for use (IFU) detail anatomic constraints to application and deployment of devices and are developed from rigorous bench testing. Nonadherence to IFU occurs frequently to avoid open surgery. The purpose of this study was to determine if IFU violations are associated with increased risk of graft-related adverse events (GRAEs) during follow-up. METHODS: This multicenter retrospective observational study included patients undergoing elective endovascular repair for abdominal aneurysmal disease with three different devices...

Cardiac surgery with cardiopulmonary bypass and cardioplegic arrest is associated with injury to the vasculature and microcirculation leading to coronary microvascular dysfunction, permeability changes and cardiac dysfunction. In the setting of cardiopulmonary bypass with cardioplegia, poorly-controlled diabetes is associated with significant changes in endothelium-dependent and independent vascular dysfunction, vascular reactivity, vascular permeability, protein expression, cell death, coronary/peripheral microcirculation and reduced vasomotor tone leading to hypotension and impaired endothelial function...

OBJECTIVE: Arterial stiffness and peripheral artery disease (PAD) are both associated with an elevated risk of major adverse cardiac events; however, the association between arterial stiffness and PAD is less well characterized. The goal of this study was to examine the association between parameters of radial artery tonometry, a noninvasive measure of arterial stiffness, and PAD. METHODS: We conducted a cross-sectional study of 134 vascular surgery outpatients (controls, 33; PAD, 101) using arterial applanation tonometry...

In spite of thorough presurgical planning, emergency situations requiring longer pedicle length may arise during anterolateral thigh (ALT) free flap surgeries. While performing vessel graft for pedicle lengthening, discrepancy may occur because of a certain genetic predisposition or vascular variation at the anastomosis site of the graft vessel and the flap pedicle. A 76-year-old male patient with neurofibromatosis type I had a 15 x 10 cm defect, which was caused by radical excision of a malignant peripheral nerve sheath tumor on his back...

In free-flap reconstruction of the lower extremity, due either to trauma or pre-existing vascular disease, healthy vessels may not be readily available in the proximity of the defect. A variety of options including a cross-leg free flap, vein grafts, arteriovenous loops, and "bridging" flaps have been used to address the issue. The purpose of this report is to present a case in which a 72-cm long extended bilateral deep inferior epigastric artery perforator (DIEP) free flap was used for coverage of a 20 × 25 cm soft tissue defect of the lower leg following a Gustilo grade IIIC fracture in a 29-year-old man...

The outcome of peripheral bypass surgery in patients at risk of limb loss is largely influenced by the anatomical integrity of the plantar arch. For this reason, in the last few decades, this area has been considered to be a sensitive territory, rarely approached surgically, and virtually untouchable by any endovascular activities. This hesitance was related to the possible damage to the thin dorsalis pedis, deep plantar, and lateral plantar arteries, together with the crucial metatarsal and digital branches arising from the arch...

BACKGROUND: The endovascular technique has been recommended over the past few years to extracranial carotid dissection and pseudoaneurysm with promising results, specially after medical therapy failure. Flow-diverting stents are an alternative for complex cases. These stents have proven to be effective treatment devices for intracranial aneurysms. OBJECTIVE: To find out all cases of flow-diverting stents in the treatment of extracranial carotid dissection with or without pseudoaneurysm and compare to our case report...

Endothelial dysfunction is one of the hallmarks of atherogenesis, and correlates with many cardiovascular risk factors. One of the features of endothelial dysfunction is the loss of nitric oxide (NO) bioavailability, resulting in derangements in the vasodilatory response of the vessel wall. Flow mediated dilatation (FMD) of the brachial artery is an accepted method for non-invasive assessment of systemic endothelial function. FMD is examined extensively in the context of cardiovascular research, and has been utilised as a routine assessment in large cohorts such as the Framingham Heart Study, Young Finns Study, and Gutenberg Heart Study...
