Abstract
Hyperbaric oxygen therapy (HBOT) involves treating patients by providing 100% oxygen through inhalation while inside a treatment pressurized chamber. The oxygen acts as a drug and the hyperbaric chamber as the dosing device. The effect of hyperbaric hyperoxia is dose dependent and, therefore, treatment depth and duration are important when considering its use. HBOT can either be the primary method of treatment or used adjunctively to medications or surgical techniques. The underpinning physiology is to bring oxygen-rich plasma to hypoxic tissue, preventing reperfusion injury, strengthening immune responsiveness, and encouraging new collagen deposition as well as endothelial cell formation.

Abstract
Necrotizing soft-tissue infection (NSTI) is a rare, severe, and fast-progressing bacterial infection associated with a high risk of developing sepsis or septic shock. Increasing evidence indicates that oxidative stress is crucial in the development and progression of sepsis, but its role in NSTI specifically has not been investigated. Some patients with NSTI receive hyperbaric oxygen (HBO2) treatment as the restoration of oxidative stress balance is considered an important mechanism of action, which HBO2 facilitates. However, a gap in knowledge exists regarding the effect of HBO2 treatment on oxidative stress in patients with NSTI. In the present observational study, we aimed to investigate HBO2 treatment effects on known markers of oxidative stress in patients with NSTI. We measured plasma myeloperoxidase (MPO), superoxide dismutase (SOD), heme oxygenase-1 (HO-1) and nitrite+nitrate in 80 patients with NSTI immediately before and after their first HBO2 treatment, and on the following day. We found that HBO2 treatment was associated with a significant increase in MPO and SOD by a median of 3.4 and 8.8 ng/mL, respectively. Moreover, we observed an HBO2 treatment-associated increase in HO-1 in patients presenting with septic shock (n=39) by a median of 301.3 pg/mL. All markers were significantly higher in patients presenting with septic shock compared to patients without shock, and all markers correlated with disease severity. High baseline SOD was associated with 90-day mortality. In conclusion, HBO2 treatment was associated with an increase in MPO and SOD in patients with NSTI, and oxidative stress was more pronounced in patients with septic shock.

Abstract
BACKGROUND The pathophysiological understanding of the inflammatory response in necrotizing soft-tissue infection (NSTI) and its impact on clinical progression and outcomes are not resolved. Hyperbaric oxygen (HBO2 ) treatment serves as an adjunctive treatment; however, its immunomodulatory effects in the treatment of NSTI remains unknown. Accordingly, we evaluated fluctuations in inflammatory markers during courses of HBO2 treatment and assessed the overall inflammatory response during the first 3 days after admission. METHODS In 242 patients with NSTI, we measured plasma TNF-α, IL-1β, IL-6, IL-10, and granulocyte colony-stimulating factor (G-CSF) upon admission and daily for three days, and before/after HBO2 in the 209 patients recieving HBO2 . We assessed the severity of disease by Simplified Acute Physiology Score (SAPS) II, SOFA score, and blood lactate. RESULTS In paired analyses, HBO2 treatment was associated with a decrease in IL-6 in patients with Group A-Streptococcus NSTI (first HBO2 treatment, median difference -29.5 pg/ml; second HBO2 treatment, median difference -7.6 pg/ml), and overall a decrease in G-CSF (first HBO2 treatment, median difference -22.5 pg/ml; 2- HBO2 treatment, median difference -20.4 pg/ml). Patients presenting with shock had significantly higher baseline cytokines values compared to non-shock patients (TNF-α: 51.9 vs. 23.6, IL-1β: 1.39 vs 0.61, IL-6: 542.9 vs. 57.5, IL-10: 21.7 vs. 3.3 and G-CSF: 246.3 vs. 11.8 pg/ml; all p < 0.001). Longitudinal analyses demonstrated higher concentrations in septic shock patients and those receiving renal-replacement therapy. All cytokines were significantly correlated to SAPS II, SOFA score, and blood lactate. In adjusted analysis, high baseline G-CSF was associated with 30-day mortality (OR 2.83, 95% CI: 1.01-8.00, p = 0.047). CONCLUSION In patients with NSTI, HBO2 treatment may induce immunomodulatory effects by decreasing plasma G-CSF and IL-6. High levels of inflammatory markers were associated with disease severity, whereas high baseline G-CSF was associated with increased 30-day mortality.

Roadkill and space use data predict vehicle-strike hotspots and mortality rates in a recovering bobcat (Lynx rufus) population. Sci Rep 2019; 9:15391. [PMID: 31659182 PMCID: PMC6817856 DOI: 10.1038/s41598-019-50931-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2019] [Accepted: 09/19/2019] [Indexed: 11/29/2022] Open
Abstract
Roadways pose challenges for conserving wide-ranging animal species. As bobcat (Lynx rufus) populations recover in Ohio, an accurate evaluation of population metrics is critical to understanding future population trajectories. In this study, we integrated multiple datasets to examine overall road mortality rates in Ohio. First, we utilized a long-term vehicle-strike dataset (1978–2017) to determine landscape and local predictors of road mortality. We found that bobcats were killed at higher rates on interstates regardless of surrounding landscape composition, but that landscape variables were useful at predicting mortality on lower-traffic roads. To explore road avoidance behaviors, we used GPS telemetry data from 18 individuals to compare road crossings along trajectory paths with random road crossings simulated using Correlated Random Walks. Bobcats exhibited avoidance of certain route types (county, municipal, and US routes). Finally, by integrating traffic volume data, road crossing behavior, and accounting for the proportion of each route type present in the study area, we estimated that a minimum of 6% and up to 18% of the bobcat population in Ohio is lost to vehicle-strikes annually. To fully understand the population level impacts of this mortality, we recommend further monitoring of age structure and sex of roadkill animals. Our results identify potential areas for mitigation of vehicle-strikes and emphasize the importance of accounting for road mortality when making management decisions for Ohio’s recovering bobcat population.

Abstract
Necrotizing fasciitis of the head and neck in children is very rare. Proper early diagnosis and adequate antibiotic therapy played an important role. Early aggressive surgical treatment is crucial for an adequate outcome. The vacuum-assisted closure and hyperbaric oxygen therapy are very useful to accelerate wound healing. A multidisciplinary management is fundamental to increase treatment success.
Introduction Necrotizing fasciitis (NF) is a severe infectious condition associated with significant morbidity and mortality and characteristically has a higher incidence in adults; pediatric cases are very rare. In this case report we describe, the clinical presentation, management and outcome of a patient with necrotizing fasciitis of the neck and head complicated with chronic osteomyelitis. Presentation of the case An 18 month-old, latin, male, diagnosed with rickets and Crouzon syndrome, twenty-four hours post- craniofacial remodeling surgery presented tissue edema, indurated skin and violaceous and well delimited lesions in the neck and head. The patient developed septic shock, acute osteomyelitis and infection of the cranial grafts. Multiple surgical lavages, debridation of the necrotic tissue and resection of the affected bone, in combination with multiple antibiotics, laboratory test methods, VAC therapy and hyperbaric oxygen were required for successful treatment and full recovery of the patient. Discussion Although early antibiotic therapy and critical care are basic for the treatment of patients with NF, early aggressive surgical treatment is crucial for an adequate outcome. Adjuvant treatment for NF such as the Vacuum-assisted closure and the hyperbaric oxygen therapy are very useful to accelerate wound healing. Moreover, special laboratory test methods such as the checkerboard can be used to determine the adequate antimicrobial combination of drugs in the case of multi resistant organisms. Conclusions Early diagnosis, adequate antibiotic therapy and aggressive surgical debridement of the necrotic tissue combined with VAC and hyperbaric oxygen therapy played an important role in the successful treatment of NF.

Abstract
In a single-centre, retrospective, case-controlled study of patients attending the Alfred Hospital in Prahran, Victoria, we assessed the effect of hyperbaric oxygen therapy (HBOT) in reducing mortality or morbidity in patients with necrotising fasciitis (NF) over a 13-year period from 2002 to 2014. A total of three hundred and forty-one patients with NF were included in the study, of whom 275 received HBOT and 66 did not. The most commonly involved sites were the perineum (33.7%), lower limb (29.9%) and trunk (18.2%). The commonest predisposing factor was diabetes mellitus (34.8%). Polymicrobial NF (type 1 NF) occurred in 50.7% and Group A streptococcal fasciitis (type 2 NF) occurred in 25.8% of patients. Mortality was 14.4% overall, 12% in those treated with, and 24.3% in those not treated with, HBOT. ICU support was required in 248 (72.7%) patients. Independent factors impacting on mortality included HBOT (odds ratio [OR] 0.42 [0.22 to 0.83], P=0.01), increased age (OR 1.06 [1.03 to 1.08], P=0.001) and immunosuppression (OR 2.6 [1.23 to 5.51], P=0.01). Mortality was linked to illness severity at presentation, however when adjusted for severity score and need for intensive care management, HBOT was associated with significant reduction in mortality.

Abstract
We report an unanticipated medication effect resulting in near-complete wound healing in a patient after beginning tadalafil therapy of 20 mg thrice daily. This patient was treated for 50 years with state-of-the art acute and then chronic wound interventions after a traumatic farm machinery accident which resulted in a devascularised foot wound. This infection was both life- and limb-threatening. The patient had undergone multiple vascular and plastic surgeries and antimicrobial therapies in addition to hospitalisations for sepsis. Limb amputation was being considered, when his urologist placed him on daily phosphodiesterase-5 inhibitor therapy, prior to unrelated urologic surgery. Remarkably, his foot wound underwent near-complete resolution and has been stable for 2 years.

Abstract
BACKGROUND Hyperbaric oxygen therapy (HBOT) involves the therapeutic administration of 100% oxygen in a pressure chamber at pressures above one atmosphere absolute. This therapy has been used as an adjunct to surgery and antibiotics in the treatment of patients with necrotizing fasciitis with the aim of reducing morbidity and mortality. OBJECTIVES To review the evidence concerning the use of HBOT as an adjunctive treatment for patients with necrotizing fasciitis (NF). Specifically, we wish to address the following questions.1. Does administration of HBOT reduce mortality or morbidity associated with NF?2. What adverse effects are associated with use of HBOT in the treatment of individuals with NF? SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE Ovid (1966 to September 2014); the Cumulative Index to Nursing and Allied Health Literature (CINAHL) Ovid (1982 to September 2014); EMBASE Ovid (1980 to September 2014); and the Database of Randomised Controlled Trials in Hyperbaric Medicine (DORCTHIM, M Bennett) (from inception to September 2014). In addition, we performed a systematic search of specific hyperbaric literature sources. This included handsearching of relevant hyperbaric textbooks; hyperbaric journals (Hyperbaric Medicine Review, South Pacific Underwater Medicine Society Journal, European Journal of Underwater and Hyperbaric Medicine, Aviation Space and Environmental Medicine Journal); and conference proceedings of the major hyperbaric societies (Undersea and Hyperbaric Medical Society, South Pacific Underwater Medicine Society, European Underwater and Baromedical Society, International Congress of Hyperbaric Medicine). SELECTION CRITERIA We included all randomized and pseudo-randomized trials (trials in which an attempt at randomization has been made but the method was inappropriate, for example, alternate allocation) that compared the effects of HBOT with the effects of no HBOT (no treatment or sham) in the treatment of children and adults with necrotizing fasciitis. DATA COLLECTION AND ANALYSIS We planned independent data collection by two review authors using standardized forms. MAIN RESULTS We found no trials that met the inclusion criteria. AUTHORS' CONCLUSIONS This systematic review failed to locate relevant clinical evidence to support or refute the effectiveness of HBOT in the management of necrotizing fasciitis. Good quality clinical trials are needed to define the role, if any, of HBOT in the treatment of individuals with necrotizing fasciitis.

Abstract
In clinical islet transplantation, isolated islets are embolized into the liver via the portal vein (PV); however, up to 70% of the islets are lost in the first few days after transplantation (i.e., too quickly to be mediated by the adaptive immune system). Part of early loss is due to instant blood-mediated inflammatory reaction, an immune/thrombotic process caused by islets interacting with complement. We have shown that glucose toxicity (GT) also plays a critical role based upon the observation that islets embolized into the PVs of diabetic athymic mice are rapidly lost but, if recipients are not diabetic, the islet grafts persist. Using donor islets resistant to the β-cell toxin streptozotocin, we have shown that intraportal islets engrafted in non-diabetic athymic mice for as little as 3 days will maintain normoglycemia when streptozotocin is administered destroying the recipient's native pancreas β-cells. What is the mechanism of GT in β-cells? Chronic exposure to hyperglycemia over-exerts β-cells and their electron transport chains leak superoxide radicals during aerobic metabolism. Here we reinterpret old data and present some compelling new data supporting a new model of early intraportal islet graft loss. We hypothesize that diabetes stimulates overproduction of superoxide in both the β-cells of the islet grafts and the endothelial cells lining the intraportal microvasculature adjacent to where the embolized islets become lodged. This double dose of oxidant damage stresses both the islets, which are highly susceptible to free radicals because of inherent low levels of scavenging enzymes, and the adjacent hepatic endothelial cells. This, superimposed upon localized endothelial damage caused by embolization, precipitates inflammation and coagulation which further damages islet grafts. Based upon this model, we predict that pre-exposing islets to sub-lethal hyperoxia should up-regulate islet free radical scavenging enzyme levels and promote initial engraftment; reinterpretation of 30 years old "passenger leukocyte" data and preliminary new data support this. Other data suggests that pre-exposure of recipients to hyperoxia could up-regulate antioxidant enzymes in the hepatic endothelium. The combination of both effects could markedly enhance early intraportal islet graft survival and engraftment. Finally, if our model is correct, current in vitro and in vivo tests used to test batches of harvested islets for viability and function prior to transplantation are poorly conceived (n.b., it is already well-known that results using these tests often do not predict clinical islet transplantation success) and a different testing paradigm is suggested.

Abstract
Oxygen treatment has been a cornerstone of acute medical care for numerous pathological states. Initially, this was supported by the assumed need to avoid hypoxaemia and tissue hypoxia. Most acute treatment algorithms, therefore, recommended the liberal use of a high fraction of inspired oxygen, often without first confirming the presence of a hypoxic insult. However, recent physiological research has underlined the vasoconstrictor effects of hyperoxia on normal vasculature and, consequently, the risk of significant blood flow reduction to the at-risk tissue. Positive effects may be claimed simply by relief of an assumed local tissue hypoxia, such as in acute cardiovascular disease, brain ischaemia due to, for example, stroke or shock or carbon monoxide intoxication. However, in most situations, a generalized hypoxia is not the problem and a risk of negative hyperoxaemia-induced local vasoconstriction effects may instead be the reality. In preclinical studies, many important positive anti-inflammatory effects of both normobaric and hyperbaric oxygen have been repeatedly shown, often as surrogate end-points such as increases in gluthatione levels, reduced lipid peroxidation and neutrophil activation thus modifying ischaemia-reperfusion injury and also causing anti-apoptotic effects. However, in parallel, toxic effects of oxygen are also well known, including induced mucosal inflammation, pneumonitis and retrolental fibroplasia. Examining the available 'strong' clinical evidence, such as usually claimed for randomized controlled trials, few positive studies stand up to scrutiny and a number of trials have shown no effect or even been terminated early due to worse outcomes in the oxygen treatment arm. Recently, this has led to less aggressive approaches, even to not providing any supplemental oxygen, in several acute care settings, such as resuscitation of asphyxiated newborns, during acute myocardial infarction or after stroke or cardiac arrest. The safety of more advanced attempts to deliver increased oxygen levels to hypoxic or ischaemic tissues, such as with hyperbaric oxygen therapy, is therefore also being questioned. Here, we provide an overview of the present knowledge of the physiological effects of oxygen in relation to its therapeutic potential for different medical conditions, as well as considering the potential for harm. We conclude that the medical use of oxygen needs to be further examined in search of solid evidence of benefit in many of the current clinical settings in which it is routinely used.

Abstract
For a large number of ischaemic, infective, inflammatory or traumatic conditions, hyperbaric oxygen therapy is either the only treatment or an adjunct that significantly reduces morbidity and mortality. The primary aim of this review is to identify clinical conditions treated in a paediatric population referred to Australian hyperbaric units. Secondary aims are to describe outcomes of treatment and detail any complications occurring during treatment or during transfer between units. This was a retrospective cohort study (January 1998-December 2011) of children treated at four Australian hyperbaric medical units. A total of 112 children underwent 1099 hyperbaric treatments for 14 indications. Ages were not normally distributed with a median age of 14 years (interquartile range 11-16; range 0.25-16 years). Treatments were completed as planned in 81.5% of cases with 25 patients' treatment terminated at the request of physicians, parents or patients. Complications relating to hyperbaric oxygen therapy occurred in 58 treatments (5.3%). Central nervous system oxygen toxicity occurred in 1:366 treatments. Our findings indicate that provision of hyperbaric oxygen therapy to children is feasible in major regional hyperbaric units and is associated with low complication rates. Management of children in an adult hyperbaric facility, however, requires significant cooperation between paediatric, intensive care and hyperbaric consultants, as the need for transfer to another hospital and prolonged transports often impacts on optimal ongoing surgical and intensive care management.

Abstract
OBJECTIVE First objective was to review cases of craniocervical necrotizing fasciitis (CCNF) at Wayne State University/Detroit Medical Center (Detroit, MI) for the last 18 years. Second was to analyze patients with and without thoracic extension for contributing factors. METHODS Retrospective review of 660 patients with necrotizing fasciitis treated at WSU/DMC from January 1989 to January 2007 was conducted. Data regarding source/extent of infection, presenting signs/symptoms, computed tomography, microbiology, antibiotics, comorbidities, number/type of operations, hyperbaric oxygen (HBO) therapy, hospital duration, complications, and overall outcome were compared/analyzed between patients with and without thoracic extension. RESULTS Twenty patients with CCNF for the past 18 years met the inclusion criteria. Ten patients had thoracic extension, and 10 patients did not have. Individuals in the thoracic extension group were likely to be older, had increased comorbidity, required more surgical debridement, experienced increased postoperative complications, and had lower overall survival. Three patients with thoracic extension underwent HBO therapy and 66% survived. CONCLUSION This is the largest single institutional review of CCNF comparing patients with and without thoracic extension. Patients with thoracic extension have a poorer outcome as follows: 60% (6/10) survival vs 100% (10/10) for those without thoracic extension (P < .05). The CCNF patients without thoracic extension treated at our institution all survived after prompt medical and surgical intervention. Overall survival of CCNF patients without thoracic extension may be attributed to rigorous wound care, broad spectrum intravenous antibiotics, aggressive surgical debridement, and vigilant care in surgical intensive care unit. The HBO therapy should be included if the patient can tolerate it.

Abstract
Necrotizing fasciitis and myositis are life-threatening infections involving the superficial fascia and musculature, respectively. Outcome depends on early diagnosis and aggressive treatment. Here, we aimed to determine prognostic factors for necrotizing soft tissue infections.The medical records of 16 consecutive patients diagnosed with necrotizing fasciitis (n = 13) and necrotizing myositis (n = 3) from 1999 to 2004 were retrospectively reviewed. Overall survival was 81.3% for necrotizing soft tissue infections, 84.6% for necrotizing fasciitis, and 66.7% for necrotizing myositis. Injection drug use was the most common cause of infection (31.3%). Frequent comorbidities were diabetes mellitus and hepatitis B and C (25.0%). As infectious agents, group A streptococci (GAS) were identified in 10 patients and multiple pathogens in 6 patients. Lethal outcome was always associated with GAS infection and streptococcal toxic shock syndrome (STSS). In our patients, myonecrosis, GAS infection, and STSS appeared to be negative prognostic factors for survival in necrotizing soft tissue infections.

Abstract
OBJECTIVE This study was performed to determine whether hyperbaric oxygen (HBO2) therapy is protective in cecal ligation and puncture (CLP)-induced sepsis and if protection is dependent on oxygen dosing. We also wished to determine whether HBO2 affected bacterial clearance or altered macrophage production of interleukin-10 (IL-10)s in the setting of CLP sepsis. Finally, we wished to determine whether the mechanism of HBO2 protection in sepsis was dependent on IL-10 production. DESIGN Prospective, experimental study. SETTING University experimental research laboratory. SUBJECTS C57BL/6 and C57BL/6 IL-10 mice. INTERVENTIONS Sepsis was induced by CLP. Mice were randomized to receive a 1.5-hr HBO2 treatment at either 1, 2.5, or 3 atmospheres absolute every 12 hrs or HBO2 at 2.5 atmospheres absolute every 24 hrs. Mice were also harvested at 24 hrs for determination of bacterial load and isolation and study of CD11b peritoneal macrophages. MEASUREMENTS AND MAIN RESULTS Survival was monitored for 100 hrs after CLP +/- HBO2 treatment. HBO2 significantly improved survival when administered at 2.5 atmospheres absolute every 12 hrs. Other treatment schedules were not protective, and treatment at 3.0 atmospheres absolute significantly worsened survival outcome. Bacterial load was significantly reduced in splenic homogenates but not peritoneal fluid at 24 hrs. Macrophages isolated from HBO2-treated mice demonstrated enhanced IL-10 secretion in response to lipopolysaccharide as compared with CLP controls. Mice genetically deficient in IL-10 expression treated with HBO2 at 2.5 atmospheres absolute every 12 hrs were not protected from CLP-induced mortality. CONCLUSION HBO2 may be protective in CLP sepsis within a window of oxygen dosing. The mechanism of HBO2 protection may be potentially linked in part to expression of IL-10, as peritoneal macrophages demonstrated enhanced IL-10 expression and IL-10 mice were not protected by HBO2 treatment.

Abstract
BACKGROUND Necrotizing fasciitis (NF) is an uncommon but serious infection of fascia and skin associated with considerable morbidity and mortality. One modality proposed for improving the outcome of this condition is hyperbaric oxygen (HBO) therapy. This is a form of medical treatment that involves intermittent inhalation of 100% oxygen under pressures exceeding the atmosphere. The aim of this article is to review current practice and evidence for the use of HBO as adjunctive therapy in the management of NF. METHODS A survey of published English literature through searches of Medline and PubMed was carried out using the following key words: "necrotizing fasciitis," "Fournier's gangrene," "necrotizing soft tissue infections," "hyperbaric oxygen therapy," "and hyperbaric oxygen chambers." RESULTS The results of studies on the use of HBO therapy in NF are inconsistent. Some studies have demonstrated that HBO can improve patient survival and decrease the number of debridements required to achieve wound control, whereas others have failed to show any beneficial effect. CONCLUSIONS Encouraging results have been achieved with the addition of HBO therapy to standard treatment regimes, thus justifying further research in this field. More robust evidence by way of a prospective randomized trial is necessary before widespread and routine use of HBO in the management of NF can be recommended.

Abstract
OBJECTIVES Necrotizing fasciitis is a challenging and potentially lethal disease; early diagnosis is of paramount importance and aggressive multidisciplinary treatment is mandatory. Overall mortality rates of 33-73% have been reported. The aim of this study was to report the experience with necrotizing fasciitis of an emergency surgery department. METHODS From October 1995 to December 2001 we observed 11 cases of necrotizing fasciitis. The patients were five men and six women, with ages ranging from 33 to 80 years. RESULTS Triggering aetiological factors were found in eight cases. In all patients a multidisciplinary approach was utilized. Every patient had a daily surgical debridement of the necrotic areas in the operating room. Polyantibiotic therapy was performed, and was changed according to culture results. After surgery, nine patients were submitted to hyperbaric oxygen therapy. Seven deaths (63.6%) were observed: two cases of pulmonary embolism and five cases of septic shock. Four patients survived; three had a complete recovery with progressive healing of the wounds, whereas one patient had severe impairment of the motility of the affected hand. The mean interval between the onset of symptoms and hospital admission was 5.4 days; for patients who ultimately died it was 7.3 days, whereas for patients who ultimately survived it was 2 days (P<0.05); moreover these patients were significantly younger than those who died (P<0.05). CONCLUSION The treatment for necrotizing fasciitis is a combination of surgical debridement, appropriate antibiotics and optimal oxygenation of the infected tissues. However, the mortality for this disease is quite high, and is related to late diagnosis and advanced age. Necrotizing fasciitis must be considered a true dramatic surgical emergency.
