NCT ID: NCT04965324 Completed - Clinical trials for Surgery--Complications

Depth of Anaesthesia and Long-term Survival: The Balanced Anaesthesia Follow-up Study

BALANCEDLT
Start date: December 19, 2012
Phase:
Study type: Observational

Anaesthetic depth and complications after major surgery: an international, randomised controlled trial - The BALANCED trial. In this large, international, randomised controlled trial that enrolled patients aged 60 years and over with significant comorbidity and at increased risk of complications after major surgery, we found no evidence that light general anaesthesia (bispectral index 50) was superior to deep general anaesthesia (bispectral index 35) in reducing 1-year mortality. The BALANCED long term follow up study will look at whether depth of anesthesia affects long term (beyond 1 year) survival. The primary hypothesis is that targetting BIS 50 will result in superior long term survival compared to targetting BIS 35. The two secondary hypotheses are that BIS titration to BIS 50 will 1. reduce local cancer recurrence or metastatic spread and consequently improve long-term survival 2. reduce postoperative delirium and associated cognitive impairment and consequently improve long-term survival Both these mechanisms would be expected to take longer to manifest as reduced survival than 1-year all-cause mortality primary outcome in the Balanced trial. Trials of cancer outcomes often use 5-year survival or similar timeframes to determine evidence of clinical benefit. A steeper cognitive trajectory due to intermediate outcomes such as delirium and cognitive impairment may take longer than 1 year to produce a clinically important difference in survival 30. The 10.6% relative risk reduction seen in the Balanced trial could translate to a statistically and clinically meaningful survival difference in this high-risk population. This population may have 5-year survival of ~80% translating to an absolute survival difference of ~2% potentially (if the ~10% RRR is maintained beyond 1 year). The alternative is that there is no long-term mortality difference which would provide continuing clinical guidance of the safety of current practice in patients who are not at high risk of delirium. This study could provide a rationale for trials in larger populations (such as the total Balanced trial population) or targeted subgroups such as cancer and delirium to provide further mechanistic insights. Long-term survival is an important patient-centred outcome. The mechanisms described above may manifest in longer-term outcomes providing a clear rationale for the current trial.

NCT ID: NCT03410849 Completed - Morbid Obesity Clinical Trials

Long-term Adverse Effects After Bariatric Surgery on Oesophagus Epithelium

Phase: N/A
Study type: Interventional

The goal of this trial is to examine long-term effects of laparoscopic gastric bypass (LRYGB) and sleeve gastrectomy (LSG) on oesophageal symptoms and disease, including the presence of Barrett oesophagus ≥ 5 years post-surgery.

NCT ID: NCT03410459 Completed - Morbid Obesity Clinical Trials

Long-term Adverse Effects After Bariatric Surgery on Bone Density

FUB-A
Start date: February 2, 2018
Phase: N/A
Study type: Interventional

The goal of this trial is to examine long-term effects of laparoscopic gastric bypass (LRYGB) and sleeve gastrectomy (LSG) on bone mineral density, fracture risk, and body composition ≥ 5 years post-surgery.

NCT ID: NCT03247036 Completed - Ischemic Stroke Clinical Trials

Long-Term Survival After Ischaemic Stroke: Ebrictus Study

EBRICTUS
Start date: January 13, 2017
Phase:
Study type: Observational [Patient Registry]

A number of large trials have confirmed the benefits of thrombolysis in acute stroke, but there are gender differences. The authors sought to examine the relationship between sex and outcome after thrombolysis. Previous reports [1-6] concerning sex-related differences in stroke management and outcome are inconsistent and sometimes difficult to interpret, and so the reasons for gender disparities in stroke outcome have remained unclear. Functional outcomes and quality of life after stroke are consistently poorer in women despite adjustment for baseline differences in age and prestroke function, and the fact that comorbidities and clinical outcomes were not different between women and men [3, 7] . Once the reasons for these differences are better understood, intervention might be possible to help provide the best care for all patients. This work is a continuation and extension of the Ebrictus Study [8-10] . Prior work has suggested sex-based differences in thrombolytic therapy in subjects with acute stroke [11] .The authors will explore whether sex might modify the effect of thrombolysis on survival and functional outcomes in patients with acute ischemic stroke [12] beyond the usually evaluated time period of 6 months after stroke and compared this with the group without thrombolytic treatment.

NCT ID: NCT03031275 Completed - Sepsis Clinical Trials

Long-term Follow Up of Adult Patients Treated With Extracorporeal Membrane Oxygenation for Respiratory Failure

Start date: January 2014
Phase: N/A
Study type: Interventional

Follow-up after treatment with Extracorporeal Membrane Oxygenation (ECMO) at the ECMO Center Karolinska. Patients: adult survivors treated with ECMO for severe refractory respiratory failure at least 5 years earlier. Investigations: brain and pulmonary radiographic morphology, cognitive testing, pulmonary function testing, exercise tolerance, quality of life and mood disorder screening.

NCT ID: NCT03004196 Completed - Clinical trials for Orthodontic Appliance Complication

Comparison of Efficacy Of Probiotic Toothpaste and Chlorhexidine Mouthwash To Reduce S.Mutans

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

Orthodontic appliance causes increase in plaque accumulation, especially around brackets, wires and attachments. Advances in orthodontics in recent time have led to improved quality of appliance and treatment procedures ultimately resulting in improvised standard of patient care. These bacteria metabolize different kind of carbohydrates accumulated around orthodontic appliances and create acidic environment in the oral cavity leading to enamel demineralization around the brackets and white spot lesions. This study was carried out to evaluate and compare the efficacy of probiotic toothpaste and chlorhexidine mouthwash in patients undergoing orthodontic treatment with individuals who are not using them.

NCT ID: NCT02933346 Completed - Clinical trials for Non-small Cell Lung Cancer

Cohort of Patients With NSCLC Treated With Nivolumab Under the ATU Program

CLINIVO
Start date: September 2016
Phase:
Study type: Observational

Our study sought to examine nivolumab efficacy and safety in advanced NSCLC patients treated under the Temporary Authorization for Use (ATU, compassionate use) setting and describe their long-term clinical characteristics, notably the treatments they received after nivolumab discontinuation. The profile of these patients shows greater conformity to that of a non-selected population, yet the clinical data collection does not reflect "real life" conditions and stops when treatment ends, which does not enable us to get an overview of post-immunotherapy treatments.

NCT ID: NCT02230800 Completed - Clinical trials for Long-term Adverse Effects of Radiotherapy for Pelvic Cancer

PPALM-Palm Oil and Pentoxifylline Against Late Morbidity

PPALM
Start date: November 25, 2014
Phase: Phase 2
Study type: Interventional

Side effects are common after treatment with radiotherapy for tumours in the pelvis and can affect the way the bowel and urinary system work as well as causing sexual difficulties, skin damage and bone problems. Problems in the bowel, bladder, sexual organs and skin mostly result from thickening of the tissues in response to radiotherapy, a process called "fibrosis". Fibrosis often worsens over time. There has been progress in treating bowel symptoms which usually are the worst problem after radiotherapy. However, even after receiving the best possible treatments, while many patients are better, they are often not cured of all their difficult problems. For some years, it has been hypothesised that if fibrosis could be treated then symptoms would improve. Recent research in laboratory animals has suggested that an effective treatment for radiation-induced fibrosis is combination therapy with a drug called Pentoxifylline together with a nutritional supplement containing gamma-tocotrienol (Tocovid SupraBio), a substance derived from palm oil. Both of these agents are simple to take and side effects are rare. This study will recruit volunteers who continue to have difficult side effects after previous radiotherapy to the pelvis despite receiving the best treatments available from a unique clinic at The Royal Marsden which has pioneered treatment for bowel problems after radiotherapy. Two out of every three volunteers who take part, will be randomly assigned to treatment with Pentoxifylline and Tocovid SupraBio, while one out of three will receive dummy pills. Neither the patients nor the staff assessing them will know which treatment they have been given. Volunteers take the active treatments or dummy tablets for a year and will be assessed regularly while on treatment and for a year afterwards. This study will show whether active treatment is more effective than dummy pills in improving the symptoms caused by radiation-induced fibrosis.
