NCT ID: NCT02580266 Withdrawn - Clinical trials for Diabetes Complications

Blood/Urine Markers for Drug Discovery for Renal Disease in Diabetes

DDRD
Start date: September 2015
Phase:
Study type: Observational

Diabetic nephropathy (kidney problems caused by diabetes) is a devastating chronic vascular complication of diabetes. New treatments are urgently needed for preventing or slowing down the progression of diabetic kidney disease. Samples of serum/plasma/urine will be obtained from patients with diabetes and different degree of renal impairment. In this project cells in culture will be treated with plasma or serum or urine; cells extracts or supernatant will be studied to screen for modulation (activation/inhibition) of different cellular pathways using gene array, metabolomic and/or proteomic. Once some cellular pathways have been identified specific analysis will be conducted on the biological material collected to confirm specific "cell signatures" that could represent potential target for treatment.

NCT ID: NCT02561715 Withdrawn - Parkinson's Clinical Trials

Lack of Awareness of Symptoms (Anosognosia) in PD: An Observational Study for People With Parkinson's

Start date: August 1, 2015
Phase:
Study type: Observational

Anosognosia is a recognised condition for people with Parkinson's, and is the result of physiological damage on brain structure. Surgical Parkinson Disease Nurse Specialists have noticed that when reviewing the pre-surgery videos 12 months post-DBS, patients have forgotten and are shocked at how bad their symptoms were prior to surgery (personal communication), which may not be reflected in the change in QoL reported. This lack of awareness, while possibly helpful in everyday life, may lead to effective treatments looking ineffective, or the benefits in QoL of effective treatment appearing reduced. This confound may not only reduce the apparent effectiveness but also the related cost-effectiveness of treatment. As cost-effectiveness is determined by both size and longevity of an effect, current methods of capturing these data may be suboptimal.

NCT ID: NCT02560363 Withdrawn - Pharmacokinetics Clinical Trials

A Study to Compare the Pharmacokinetics of Different Formulations of AZD9977 and the Influence of Food in Healthy Male Subjects

Start date: November 2015
Phase: Phase 1
Study type: Interventional

This is an open-label, randomized, cross over single oral dose study to compare the pharmacokinetics of different formulations of AZD9977 in Part A and the influence of food in Part B in healthy male subjects

NCT ID: NCT02539953 Withdrawn - Hypotension Clinical Trials

Ambulatory Blood Pressure Monitoring in Rivaroxaban Therapy

Start date: April 2015
Phase: N/A
Study type: Interventional

One in ten patients on rivaroxaban therapy have dizziness and reductions in blood pressure. The investigators intend to monitor the ambulatory blood pressure of such patients in order to assess whether this is a true haemodynamic effect.

NCT ID: NCT02535260 Withdrawn - Pregnancy Clinical Trials

Clearblue Advanced Fertility Monitor Consumer Three Cycle at Home Study

Start date: n/a
Phase:
Study type: Observational

This study will assess the use of the new Clearblue Advanced Fertility Monitor in a home setting for three menstrual cycles or until pregnancy is achieved (whichever comes first) by female volunteers seeking to get pregnant.

NCT ID: NCT02525640 Withdrawn - Hearing Loss Clinical Trials

Hearing Handicap in Patients With Single Sided Deafness

Start date: August 1, 2015
Phase: N/A
Study type: Interventional

Single sided deafness (SSD) refers to asymmetrical hearing loss, where there is a significant worsening of hearing in one ear compared to the other. In Cambridge, the investigators see large numbers of patients with SSD caused by vestibular schwannomas, due to their affiliation with the Neuro-Otology Department, with over 100 new SSD patients being referred every year. Only a small number of studies have explored hearing handicap for those with SSD, and music appreciation has not been investigated, to the best of the investigators knowledge, in this patient group. In the limited number of studies conducted on those with single sided deafness, often only one or two outcome measures have been used, or the patient group has been small. The investigators have a large group of patients with a wide range of aetiologies who have completed several questionnaires as part of their treatment in the single sided deafness clinic and the investigators would like to analyse these data. At present there are different devices available on the NHS for the management of SSD and many studies have explored benefits of Bone Anchored Hearing Aids (BAHA). There is an under-representation of studies looking specifically at CROS aid devices which is relevant given the cost differences involved between devices. Study goals and objectives - To find out what factors drive hearing handicap in SSD patients by analysing the results of several different well validated hearing handicap questionnaires - To find out whether or not it is possible to change hearing handicap in this patient group by looking to see if there is an improvement in questionnaire scores post treatment. - The investigators will also look at a sub-group who will be fitted with both traditional wired CROS aids and more up-to-date wireless aids which have been funded through a research grant, in order to assess whether these are more beneficial. - The investigators will use a new questionnaire developed in-house to further explore the impact of single sided deafness on music appreciation.

NCT ID: NCT02522273 Withdrawn - Clinical trials for Measurement of Fetal Blood Lactate

Evaluation of the 'SensPoint' Lactate Meter in the Estimation of Foetal Scalp Blood and Umbilical Cord Blood Lactate

Start date: October 2015
Phase:
Study type: Observational

A cardiotocograph (CTG) can be used in labour to assess the heartbeat and well-being of a baby. An abnormal CTG may be a sign that a baby has low oxygen levels (hypoxia) and is becoming distressed. In this situation a blood test can be taken from the scalp of the baby. A high lactate level in the blood indicates that urgent delivery is required to prevent long-term harm to the newborn. SensPoint is a new medical device that measures lactate. It has several potential benefits over the current method of measuring lactate in that it is a portable hand-held device (allowing for use in the delivery room), requires a much smaller volume of blood and produces results more quickly than the current method of measuring lactate. Before a new device is adopted into clinical practice, it is important that it is first confirmed that it is accurate and reliable for its intended use. This study will evaluate the ability of the SensPoint device to accurately and reliably detect lactate in fetal and umbilical cord blood by comparing its performance to the reference device currently in use.

NCT ID: NCT02507050 Withdrawn - Clinical trials for Coronary Artery Disease

Ivabradine and Post-revascularisation Microcirculatory Dysfunction

MICRO-PCI
Start date: March 2016
Phase: Phase 4
Study type: Interventional

The aim of the study is to test whether, in patients with angina and flow limiting epicardial coronary artery disease, pre-treatment with Ivabradine, as opposed to beta blockers, will reduce post percutaneous coronary intervention induced microvascular dysfunction.

NCT ID: NCT02454621 Withdrawn - Smoking Cessation Clinical Trials

Trial of the Smoking Cessation Volitional Help Sheet in Primary Care

Start date: May 2015
Phase: Phase 1/Phase 2
Study type: Interventional

The study will recruit patients who smoke from a general practice clinic and randomize them either to: (1) form implementation intentions by linking in memory situations in which they are tempted to smoke with strategies to avoid smoking in those situations using a volitional help sheet, or (2) to consider the situations in which they are tempted to smoke alongside possible strategies to avoid smoking as presented in the volitional help sheet but not to form implementation intentions. The effects on self-reported smoking will be assessed 1 month post-intervention.

NCT ID: NCT02407587 Withdrawn - Hearing Loss Clinical Trials

Neuroplastic Changes Seen in Cochlear Implants With Preserved Hearing

Start date: May 2013
Phase: N/A
Study type: Interventional

Investigators hope to study patients with 1 cochlear implant and who have had hearing preservation surgery and compare the changes in the brain of these patients with normal hearing patients by doing a scan of the brain when listening to speech. The information investigators collect may help investigators to understand how the brain learns to hear with a cochlear implant and whether it uses the same areas in the brain to listen as in normal hearing patients as well as predict which patients will do well with a cochlear implant as a very specialised operation is needed to insert the cochlear implant in to the ear and is done by very few surgeons in the country. After the operation, patients need several months of teaching to help them learn how to hear through the implant. Having a cochlear implant requires a lot of cooperation and time from the patient and if investigators could understand how the brain learns to hear with a cochlear implant and predict which patients do well and why then we may be able to avoid unnecessary procedures.
