Metabolic and Hemodynamic Reserve in Pediatric SCA

ChildOnly4 more

The purpose of this research study is to better understand how blood flow and metabolism change can influence brain development in the early decades of life. SCA participants and healthy controls are age and sex-matched for comparison. Within the SCA cohort, children with infarcts may have thinner cortices than those without, reflecting a greater loss. The investigators will examine brain blood flow and metabolism using magnetic resonance imaging (MRI). The brain's blood vessels expand and constrict to regulate blood flow based on the brain's needs. The amount of expanding and contracting the blood vessels may vary by age. The brain's blood flow changes in small ways during everyday activities, such exercise, deep concentration, or normal brain growth. Significant illness or psychological stress may increase the brain's metabolic demand or cause other bigger changes in blood flow. If blood vessels are not able to expand to give more blood flow when metabolic demand is high, the brain may not get all of the oxygen it needs. In extreme circumstances, if the brain is unable to get enough oxygen for a long time, a stroke may occur. Sometimes small strokes occur without other noticeable changes and are only detectable on an MRI. These are sometimes called "silent strokes." In less extreme circumstances, not having a full oxygen supply may cause the brain to grow and develop more slowly than when it has a full supply. One way to test the ability of blood vessels to expand is by measuring blood flow while breathing in carbon dioxide. Carbon dioxide causes blood vessels in the brain to dilate without increasing brain metabolism. During this study participants may be asked to undergo a blood draw, MRI, cognitive assessments, and brief questionnaires. The study team will use a special mask to control the amount of carbon dioxide the participants breathe in.

Pathophysiology of Anemia in PICU Survivors

Anemia

In 2007, the TRIPICU trial which demonstrated the safety of tolerating anemia in critically ill children through avoidance of unnecessary red cell transfusions. This landmark study led to practice changes and a reduction in the use of red cell transfusion during PICU stay. However, although this restrictive approach appears safe in the acute setting of PICU, there is a paucity of data regarding its long-term impact on the burden of anemia at discharge. Although 98% of patients now survive their PICU stay, we and other groups have documented that around 50% of PICU admissions will be anemic at discharge. A major contributing factor may be the increasing adoption of restrictive red cell transfusion policies during the phase of ICU admission. Given that there are approximately 9000 PICU admissions/year in Canada, this represents almost 4500 children are discharged with anemia. The causes of anemia are multifactorial, including inflammation, co-morbidities and nutritional, including iron depletion. Anemia, in particular iron deficiency anemia, is well recognized to be associated with abnormal neurocognitive development in infants and young children. Anemia can also contribute to lower exercise tolerance levels impeding children's development and quality of life. This protocol describes a prospective observational cohort study of PICU survivors, to better understand the epidemiology of anemia at and after PICU discharge. The primary aim will be to determine the prevalence of anemia at 2 months after PICU discharge (primary aim) as well as at 6 and 12 months follow-up (secondary aim). We will evaluate the association of anemia with neurocognitive dysfunction, and quality of life (secondary aim). We will also investigate the pathophysiology of anemia after PICU discharge. We will perform blood tests on anemic patients to measure inflammatory markers as well as markers of iron deficiency (including the new biomarker hepcidin) (tertiary aim).All patients included will be followed while hospitalized in the PICU, as well as at dedicated clinics at 2, 6, and 12 months after PICU discharge. Anemia affects a large proportion of PICU survivors. This study will allow us to better understand the long-term prevalence and causes of anemia in this population as well as potential association with long-term outcome. Anemia (specifically iron responsive anemia) could be a potentially readily modifiable risk factor, to improve the long-term well-being of these children.

Nutritional Status of Women Undergoing in Vitro Fertilization

IVFBody Weight3 more

Infertility affects around 15 % of couples in their reproductive years. Even though the use of assisted reproductive technologies (ART) in aforementioned couples is increasing, their success rate is still relatively low. Hence it is important to identify and better understand potential modifiable dietary and lifestyle risk factors that may influence the success of ART. This study will include women undergoing IVF with a view to investigating the relationship between preconception dietary patterns, body composition, physical activity level, serum values of vitamin B9, vitamin B12 and vitamin D and the outcomes of IVF, such as the number of obtained oocytes, fertilization rate and clinical pregnancy. Main hypothesis is that women undergoing IVF, who eat a balanced diet, maintain healthy body weight and have adequate serum levels of vitamin B9, vitamin B12 and vitamin D, have a higher chance of achieving better IVF outcomes.

The Optimization of Conditioning Regimen for HLA Matched HSCT in SAA

Severe Aplastic Anemia

Hematopoietic stem cell transplantation (HSCT) from a human leukocyte antigen (HLA) -matched donor is an effective option for severe aplastic anemia (SAA), but there is no standardized and recommended conditioning regimen. The occurrence of mixed chimerism after transplantation is associated with secondary graft failure and poor failure-free survival. Previous studies have shown that Fludarabine (Flu)/ Cyclophosphamide (Cy)/ antithymocyte globulin (antithymocyte globulin), ATG) and Cy/ATG conditioning regimens had higher rates of mixed chimerism and poorer failure-free survival. A small cohort study has suggested that adding busulfan to Flu/Cy/ATG or Cy/ATG can reduce the incidence of mixed chimerism and improve failure-free survival. This study was a prospective, multicenter, randomized controlled trial to compare the efficacy and safety of different conditioning regimens in the treatment of severe aplastic anemia (SAA) after hematopoietic stem cell transplantation (HSCT) from HLA-identical sibling or unrelated donor.

Can Pre-operative Anemia be Timely Identified and Optimized in Patients Awaiting Primary Arthroplasty...

AnemiaHip Osteoarthritis

Reducing the occurrence of anemia (low circulating hemoglobin levels) post-surgery has been associated with improved outcome, as it reduces complications and allows for faster return to pre-operative function. Post-operative hemoglobin level is dependent upon its pre-operative value (for a given amount of blood loss). About 17% of patients at the Ottawa Hospital (TOH), will be anemic pre-operatively, and if left untreated the patients will have significantly inferior outcomes compared to non-anemic patients. In order to improve outcomes, when a patient is identified as anemic, typically at the pre-operative assessment clinic, he/she is invited to be reviewed and optimized at the Pre-operative Blood Optimization Clinic (PBOC). However, only a quarter of anemic patients are seen in the PBOC due to the lack of time available between anemia identification and surgery and the current resources available. This project will focus on hemoglobin level optimization of pre-operative hip and knee, primary, arthroplasty patients to demonstrate whether early assessment and treatment of pre-operative anemia can be successfully integrated into practice and its impact on post-operative outcomes. Patients will be randomly assigned to either the current standard of care pathway with an anemia test at the pre-operative assessment clinic (2-4 weeks before surgery), at which time they have the option to seek treatment. Patients who are randomly selected to be in the experimental group, will undergo a test to detect anemia at the time they consent for surgery, which is usually 4-6 months prior to surgery. Patients with anemia, will be invited for treatment at the blood optimization clinic at this time. In doing so, this project will test whether timely identification and simple measures is feasible and whether such practice can reduce the overall anemia burden and ultimately improve patient outcome.

Statins in Patients With Clonal Cytopenia of Undetermined Significance (CCUS) and Myelodysplastic...

Clonal Cytopenia of Undetermined SignificanceMyelodysplastic Syndromes

Patients with clonal cytopenia of undetermined significance (CCUS) and lower-risk myelodysplastic syndromes (MDS) have a life expectancy of 5 to 10 years. Mortality in these patients results from progression of disease to higher-risk MDS or acute myeloid leukemia (AML) and cardiovascular events. Currently there are no FDA-approved treatments with the potential to improve survival of patients with CCUS and lower-risk MDS. Statins are an appealing class of drugs to consider in this situation as preclinical data support their potential to suppress progression of myeloid malignancy, and they have a well-established role in prevention of major cardiovascular events. This is a pilot study to explore the role of statins in treatment of patients with CCUS and lower-risk MDS. In this study, change in variant allele frequency (VAF) of somatic mutations present at diagnosis will be used as a surrogate marker of response to statin therapy. The hypothesis is that the use of statins at diagnosis of CCUS or lower-risk MDS will delay or prevent the expected increase in the VAF of somatic mutations over time.
