Effect of Casodex on Tumour Hypoxia - Prostate Cancer

Prostatic Neoplasms

Prostate cancers, in common with many other tumours, are often hypoxic; that is, they have low levels of oxygen. It is thought that tumour hypoxia may hasten the progression of cancers and make them more resistant to treatment. One previous study has suggested that hormone therapy, such as Casodex, may improve the prostate oxygen level. This study is designed to test that finding.

Identification of Secreted Markers for Tumor Hypoxia in Patients With Head and Neck or Lung Cancers...

Head and Neck CancerLung Cancer3 more

The purpose of this study is to identify and confirm new blood and tissue markers for prognosis and tumor hypoxia. Tumor hypoxia, or the condition of low oxygen in the tumor, has been shown to increase the risk of tumor spread and enhance tumor resistance to the standard treatment of radiation and chemotherapy in head and neck and lung cancers. We have recently identified several proteins or markers in the blood and in tumors (including osteopontin, lysyl oxidase, macrophage inhibiting factor and proteomic technology) in the laboratory that may be able to identify tumors with low oxygen levels or more aggressive behaving tumors.

Identification of a Pool of miRNA to Improve Early Management of Perinatal Asphyxia and Hypoxic...

Hypoxic-Ischemic EncephalopathyAsphyxia Perinatal

Hypoxic-ischemic encephalopathy is the most common cause of neurological damage in the neonatal period. It has an incidence of about 1.5-2.5% of livebirths in developed countries. It is associated with a high rate of mortality and morbidity. Major neurological outcomes such as cerebral palsy, mental retardation, learning disabilities, epilepsy occur in approximately 25% of survivors. The diagnostic and prognostic tools currently available for enrollment have limitations and additional reliable biomarkers are needed for all phases of clinical management. Sarnat staging has taken on a role in identifying those infants who may benefit from treatment of hypothermia, resulting in the need for neurological evaluation and staging within 6 hours of life. Therapeutic hypothermia is still the best therapeutic treatment. A new tool in neuroscience research is represented by micro-ribonucleic acid (microRNA) profiling. The presence of microRNAs in blood, urine and saliva and the ability to measure their levels non-invasively has opened new doors in the search for peripheral biomarkers for the diagnosis and prognosis of neurodegenerative diseases and also as possible pharmacological targets. The aim of the present study is to analyze a specific cluster of miRNAs selected from data obtained by macroarray (NGS Pannel) on the entire microRNAome in healthy newborns with normal cord arterial pH value (7.26-7.35) as control cases and in newborns with fetal metabolic acidosis with a pH threshold value lower than 7.12 of the blood gas analysis from cord arterial blood. This latter group will be further stratified into two groups, neonates who will practice therapeutic hypothermia according to current guidelines and a further group who will not practice therapeutic hypothermia. This study will make a further international contribution in evaluating and identifying the potential of microRNAs as diagnostic and prognostic biomarkers in perinatal asphyxia and hypoxic ischemic encephalopathy. Furthermore, the study aims to identify specific microRNA sequences as new possible markers to be used as an additional parameter for the enrollment of therapeutic hypothermia, especially in cases of mild hypoxic-ischemic encephalopathy.

Assessment of Hypoxia Before Radioembolization Treatment With 18F-FMISO PET

RadioembolizationRadiotherapy2 more

Hypoxia is a known factor for resistance to radiotherapy in tumors. Response to transarterial radioembolization is known to be variable between different patients even if the same dose of radiation was delivered. In this study the investigators aim to quantify the hypoxia in the primary and secondary tumors of liver with 18F-FMISO PET before radioembolization and to prove any effect of the hypoxia, if present, on the dose that should be delivered to tumor to ensure treatment response.

Safeguarding the Brain of Our Smallest Children-IIIv (SafeBoosC-IIIv)

HypoxiaInfant2 more

The objective of the SafeBoosC-IIIv trial is to evaluate cerebral oximetry added to usual care versus usual care in mechanically ventilated newborns. The hypothesis is that the intervention will decrease a composite outcome of death or moderate to severe neurodevelopmental disability and/or increase the mean PARCA-R non-verbal cognitive score at two years of corrected age.

Zn-DDC to Target Hypoxia-NFkappaB-CSCs Pathway in Multiple Myeloma

Multiple Myeloma

The outlook for patients with haematological malignancies remains challenging. It has been shown in some early cancer studies that a particular drug called Zn-DDC otherwise known as Imuthiol is highly toxic to cancer stem cells. Imuthiol has been intravenously used in clinical trials with an excellent safety record. Recent novel therapy and immunotherapy in haematological malignancies have improved outcome and survival but come with an increasing cost burden. Imuthiol could be an ideal affordable drug to study on it's own as well as in combination with other drugs in myeloma and other haematological malignancies. This may lead to potential combination therapies which will be very effective as well as affordable in the future. There is the need to look to see if this drug, Imuthiol and along with complementary drugs lenalidomide (Revlimid) and pomalidomide (Pomalyst) can help in haematological malignancy treatment. In order to do this there is the need to see how the cancer cells respond to the drugs in the laboratory before being able to trial the drug (or combination of drugs) out for treatment. The success of this study may lead to quick translation of Imuthiol into haematological malignancy treatment.

Impact of Nocturnal Hypoxemia on Glucose in High Altitude Sleep Disordered Breathing

Sleep-Disordered BreathingGlucose Intolerance

Sleep disordered breathing is associated with impaired glucose tolerance and incident diabetes. Nocturnal hypoxemia is a potential stimulus of glucose intolerance. It is especially severe and highly prevalent in high altitude residents. Intervening on nocturnal hypoxemia may therefore improve glucose control and decrease the public health burden in high altitude populations. The objective of this study is to examine the impact of hypoxemia on glucose homeostasis in high altitude residents. The investigators will address this objective by examining the effect of supplemental oxygen on glucose in a randomized cross-over study.

Accuracy of Pulse Oximeters With Profound Hypoxia At Rest (NIHO18)

Hypoxia

The aim of this study is to determine the accuracy of devices called pulse oximeters, which measure blood oxygen by shining light through fingers, ears or other skin, without requiring blood sampling. Study will be used with patients at rest.

Comparison of Multiple Oxygenation Targets With Different Oximeters in Chronic Obstructive Pulmonary...

COPD ExacerbationPneumonia2 more

The oximeter is an instrument for monitoring patients receiving oxygen therapy. It displays pulse oxygen saturation (SpO2), which is a reflection of arterial oxygen saturation (SaO2). An accurate SpO2 value is essential for optimal management of the O2 flow delivered to patients. Several factors can influence this measurement and the choice of ventilatory support: the type of oximeter used, skin pigmentation and the oxygenation goal. The objective of our study is to evaluate the impact of the oxygenation goal and the oximeter used on oxygen flows in patients with COPD (or with hypercapnia, or at risk of hypercapnia) and in patients without COPD (in particular pneumonia, pulmonary fibrosis and other pathologies) Our hypothesis is that the SpO2 target and oximeter used will have an impact on oxygen flows and that these effects will be synergistic in these different populations.
