Objectives: To define guidelines for BK polyomavirus (BKPyV)-associated haemorrhagic cystitis (BKPyV-HC) after paediatric and adult HSCT. Methods: Review of English literature and evidence-based recommendations by expert consensus. Results: BKPyV-HC occurs in 8%-25% of paediatric and 7%-54% of adult recipients undergoing allogeneic HSCT. Diagnosis requires the triad of cystitis, macro-haematuria and high urine BKPyV loads >7 log10 copies/mL, and exclusion of other relevant aetiologies...

A 17-year-old female developed invasive rhinocerebral mucormycosis during intensive re-induction chemotherapy for relapsed pre-B acute lymphoblastic leukemia. Due to the high case fatality rate for invasive mucormycosis in profoundly immunosuppressed patients, an aggressive treatment regimen was pursued. In addition to the standard of care treatments with intravenous amphotericin and aggressive surgical debridements, she received intraventricular amphotericin to the brain via an Ommaya reservoir, hyperbaric oxygen treatments, filgrastim, intravenous immunoglobulin and anti-fungal in vitro synergy testing to allow for more targeted antifungal therapy with the addition of micafungin...

BACKGROUND AIMS: Umbilical cord blood (UCB) provides an alternative source for hematopoietic stem/progenitor cells (HSPCs) in the treatment of hematological malignancies. However, clinical usage is limited due to the low quantity of HSPCs in each unit of cord blood and defects in bone marrow homing. Hyperbaric oxygen (HBO) is among the more recently explored methods used to improve UCB homing and engraftment. HBO works by lowering the host erythropoietin before UCB infusion to facilitate UCB HSPC homing, because such UCB cells are not directly exposed to HBO...

Hyperbaric oxygen (HBO) therapy and neural stem cell (NSC) transplantation can improve traumatic brain injury (TBI) clinically. This study aimed to investigate the mechanism of HBO promoting NSC proliferation and neurological recovery after TBI. Twenty-four Sprague-Dawley rats were divided randomly into three groups: a sham group, a TBI group (constructed using Feeney's free-fall method), and an HBO-treated TBI group. Neurological function was evaluated by Neurological Severity Scores on days 1, 3, and 7, and we found that TBI-induced poor neurological function was improved by HBO...

Hyperbaric oxygen therapy (HBOT) is a noninvasive widely applied treatment that increases the oxygen pressure in tissues. In cochlear implant (CI) research, intracochlear application of neurotrophic factors (NTFs) is able to improve survival of spiral ganglion neurons (SGN) after deafness. Cell-based delivery of NTFs such as brain-derived neurotrophic factor (BDNF) may be realized by cell-coating of the surface of the CI electrode. Human mesenchymal stem cells (MSC) secrete a variety of different neurotrophic factors and may be used for the development of a biohybrid electrode in order to release endogenously-derived neuroprotective factors for the protection of residual SGN and for a guided outgrowth of dendrites in the direction of the CI electrode...

Umbilical cord blood (UCB) engraftment is in part limited by graft cell dose, generally one log less than that of bone marrow (BM)/peripheral blood (PB) cell grafts. Strategies toward increasing hematopoietic stem/progenitor cell (HSPC) homing to BM have been assessed to improve UCB engraftment. Despite recent progress, a complete understanding of how HSPC homing and engraftment are regulated is still elusive. We provide evidence that blocking erythropoietin (EPO)-EPO receptor (R) signaling promotes homing to BM and early engraftment of UCB CD34(+) cells...

Tissue engineering (TE) has provided promising strategies for regenerating tissue defects, but few TE approaches have been translated for clinical applications. One major barrier in TE is providing adequate oxygen supply to implanted tissue scaffolds, since oxygen diffusion from surrounding vasculature in vivo is limited to the periphery of the scaffolds. Moreover, oxygen is also an important signaling molecule for controlling stem cell differentiation within TE scaffolds. Various technologies have been developed to increase oxygen delivery in vivo and enhance the effectiveness of TE strategies...

OBJECTIVE: Hemorrhagic cystitis (HC) is a generally self-limited complication of hematopoietic stem cell transplantation (HSCT). It may occur in the early or late posttransplant period and can promote sometimes severe morbidity. We analyzed our data regarding HC in allogeneic HSCT patients in order to establish the efficacy of hyperbaric oxygen (HBO) therapy in severe HC and to document the main problems during its use. METHODS: Between March 1993 and August 2006, 161 patients received allogeneic HSCT...

Transplantation of umbilical cord-derived mesenchymal stem cells (UC-MSCs) for repair of traumatic brain injury has been used in the clinic. Hyperbaric oxygen (HBO) treatment has long been widely used as an adjunctive therapy for treating traumatic brain injury. UC-MSC transplantation combined with HBO treatment is expected to yield better therapeutic effects on traumatic brain injury. In this study, we established rat models of severe traumatic brain injury by pressurized fluid (2.5-3.0 atm impact force). The injured rats were then administered UC-MSC transplantation via the tail vein in combination with HBO treatment...

Oxygen is an essential gas. Oxygen is also a biological medicine. Hyperbaric oxygen therapy is a treatment which is based on the respiration of pure oxygen in a particular pressurised environment (hyperbaric chamber). The pressure allows the diffusion of oxygen into the blood at a concentration which is ten/fifteen/twenty times the normal level. The increase in oxygen in bodily liquids stimulates the synthesis of a gas, nitric oxide (NO), which has a powerful anti-inflammatory effect and promotes the formation of new blood vessels (also through the employment of stem cells) thus accelerating the healing of wounds...

Osteonecrosis of the jaw (ONJ) has been associated with the use of aminobisphosphonates and denosumab. The vast majority (>90%) of cases occur in the oncology patient population receiving high doses of intravenous bisphosphonates or subcutaneous denosumab. The incidence of ONJ in the osteoporosis patient population is very low and is estimated at 1-90 per 100,000 patient-years of exposure. In the oncology patient population the incidence appears to be related to dose and duration of exposure, and prevalence has been estimated to be as high as 18...

The current debate surrounding the use of hyperbaric oxygen (HBO2) for neurological indications, specifically mild to moderate chronic traumatic brain injury (mTBI) and post-concussion syndrome (PCS), is mired in confusion due to the use of non-validated controls and an unfamiliarity by many practitioners of HBO2 therapy with the experimental literature. In the past 40 years, the use of an air sham (21% oxygen, 1.14-1.5 atmospheres absolute/atm abs) in clinical and animal studies, instead of observational or crossover controls, has led to false acceptance of the null hypothesis (declaring no effect when one is present), due to the biological activity of these "sham" controls...

We present the case of a 69 year-old gentleman with non-healing ulcers of the bilateral medial malleoli as a result of graft-versus-host disease (GvHD). The patient discussed was diagnosed with stage IV mantle cell lymphoma. Over the course of 4 years the patient was treated with autologous stem cell transplant, later reduced-intensity allogeneic stem cell transplant, and finally donor lymphocyte infusion due to recurrence. Following these therapies, the patient developed extensive GvHD that resulted in bilateral non-healing ulcers of the medial malleoli...

Hemorrhagic cystitis (HC) is a diffuse inflammation of the bladder of an infectious or non-infectious etiology, causing bleeding of the bladder mucosa. There are no explicit guidelines defining the appropriate treatment of HC. Hyperbaric oxygen therapy (HBO) is a non-invasive method involving the use of 100 % oxygen under increased pressure, which penetrates to poorly perfused areas. The most appropriate group for treatment with HBO is patients with BK virus-associated HC after allogenic human stem cell transplantation (alloHSCT)...

Head and neck cancers have been widely studied concerning their sensitivity to radiation therapy. Several parameters affect tumour response to radiation therapy. Some parameters are linked to the tumour. Large or invasive tumours, localization, such as oral cavity or adenopathy, are factors of radioresistance. Others parameters are linked to the patients themselves. Tobacco intoxication during radiotherapy and a low hemoglobin level contribute to radioresistance. More recently, a positive human papilloma virus (HPV) status has been reported to positively affect radiosensitivity...
