NCT ID: NCT03759002 Completed - Clinical trials for Cardiovascular Diseases

Association of Mean Platelet Volume and Cardiovascular Disease in Children With End Stage Renal Disease.

Start date: February 1, 2016
Study type: Observational

Cardiovascular disease (CVD) is the major risk factor for death in end stage renal diseases (ESRD). Approximately 80% of ESRD patients have some degrees of left ventricular abnormalities at initiation of dialysis. Carotid intima media thickness (CIMT) has been widely accepted as an useful marker to assess CVD in ESRD children. In addition, cardiac mechanics parameters are used to evaluate cardiac function more precisely. However, measuring CIMT and cardiac mechanics parameters are expensive and difficult to perform as a routine method. Mean platelet volume (MPV) is a hematological index which shows the size of platelets. Uremic state causes inflammatory condition that affects MPV. Previous studies on people with normal renal function have shown that this parameter can also have association with CVD. However the data in children with ESRD is scarce. The aim of this study is to find a simple hematologic marker to use regularly in ESRD children finding patients at risk of CVD. Therefore, we will investigate the relationship between mean platelet volume and CIMT and cardiac mechanic parameters in children with ESRD.

NCT ID: NCT03742570 Completed - Children Clinical Trials

Turkish Version of Childhood Bladder and Bowel Dysfunction Questionnaire

Start date: April 13, 2016
Study type: Observational

Objectives:The aim of this study was to translate the Childhood Bladder and Bowel Dysfunction Questionnaire into Turkish, adapt it for use with parents of 5-12 year old children and determine the reliability and construct validity of the Turkish version. The main hypothesis of our study was that it would be possible to translate and culturally adapt the CBBDQ into a Turkish version, so that Turkish parents could understand it. Additionally, we hypothesized that the Turkish version would provide adequate internal consistency and test-rest reliability and acceptable construct validity. Methods:The Childhood Bladder and Bowel Dysfunction Questionnaire was guideline driven translated into Turkish and administered twice, at 7-day intervals, to parents of children to assess test-retest reliability. Cronbach's α was used for internal consistency and the inter-rater correlation coefficient was used to calculate test-retest reliability. The Dysfunctional Voiding and Incontinence Scoring System (DVISS) and Pediatric Quality of Life Inventory (PedsQL) in 5-7, 8-12 years old children were used as an external criterion to estimate construct validity.

NCT ID: NCT03719703 Enrolling by invitation - Hypertension Clinical Trials

Health in Childhood Following Assisted Reproductive Technology

Start date: November 2018
Study type: Observational [Patient Registry]

The purpose of this trial is to investigate the metabolic and cardiovascular health in children aged 6-8 years born after in-vitro fertilization with frozen embryo transfer

NCT ID: NCT03671057 Recruiting - Surgery Clinical Trials

Effectiveness Study "HospiAvontuur":

Start date: October 1, 2017
Phase: N/A
Study type: Interventional

Preoperative anxiety is frequently experienced by children undergoing anaesthesia and surgery and being separated from parents during the operation. It is associated with a significant number of adverse outcomes such as maladaptive behavioural changes and increased postoperative analgesic requirements. Pharmacological interventions such as midazolam are widely used to decrease preoperative anxiety in children. However, premedication may be associated with undesirable effects such as paradoxical reactions, prolonged sedation and adverse behavioural changes.The aim of this study is to develop and use a serious game, HospiAvontuur, which can be used during the preparation of children for an admission at the hospital. By using this game the researchers aim to reduce the usage of pharmacological interventions and to increase the use of non-pharmacological interventions, such as HospiAvontuur.

NCT ID: NCT03608956 Recruiting - Acute Kidney Injury Clinical Trials

Renal Oxygen Saturation and Its Association With Acute Renal Injury

Start date: May 1, 2018
Study type: Observational

Peri-operative renal dysfunction is a major mortality and morbidity cause following cardiac and major vascular surgery. Although several intra-operative strategies are proposed for better outcomes, no effective and fast resulting test is available to be done in operating rooms to assess renal functions. Urine and blood markers as serum creatinine, urine output, fractional excretion of sodium and urea are used for early diagnosis of acute renal injury. Near infrared spectroscopy (NIRS) assesses tissue oxygenation especially cerebral regional oxygen saturation. The benefit of NIRS followups of cerebral and somatic (liver, kidney, mesentery) oxygenation in pediatric cardiovascular surgery patients are demonstrated by studies.

NCT ID: NCT03563196 Completed - Cardiac Surgery Clinical Trials

Diagnosis Of Pulmonary Complications After Cardiac Surgery In Children

Start date: September 2016
Study type: Observational

Pulmonary complications are frequent in cardiac surgery, representing an important cause of morbidity, prolongation of hospital stay and need for repeated examinations.Chest X-rays are done routinely and even multiple times to detect such complications.Lung ultrasonography is an alternative test to detect pulmonary complications that can be done easily on bedside. Regularly done Chest X-ray exposes patient to ionizing radiation which can be reduced with ultrasonography. Lung ultrasound is gaining popularity in recent years as a non-invasive,radiation-free tool for the diagnosis of various acute and chronic pulmonary diseases due to its bedside convenience, accuracy, and free of radiation.There is increasing evidence to support the use of Lung ultrasound in acute care setting and post-cardiac surgical patients are also considered critically ill. The purpose of this study is to compare diagnostic performance of lung ultrasound in comparison to chest X-ray to detect pulmonary complication after cardiac surgery in children.

NCT ID: NCT03539809 Recruiting - Children Clinical Trials

Branched Chain Amino Acids Ratio in Medical Foods

Start date: June 1, 2018
Phase: N/A
Study type: Interventional

This study will evaluate the branched-chain amino acids (BCAA) ratio in the medical foods formulated for Methylmalonic and Propionic Acidemias (MMA/PROP) patients. We will recruit 6 healthy children between 6-10y (3 boys and 3 girls). They will be given amino acid-based shakes and protein free cookies. Using a minimally invasive stable isotope based technique, we will be able to determine the optimal ratio of BCAA to be added in the medical foods for the MMA/PROP subjects.

NCT ID: NCT03460002 Recruiting - Children Clinical Trials

Vaccine Campaign Effects on General Hospital Admissions and Mortality Among Children

Start date: November 2016
Phase: Phase 4
Study type: Interventional

The world is set on eradicating measles and polio infections in the coming decade. Once both infections are under control, campaigns with measles and oral polio vaccines will be phased out. This might do more harm than good for child survival in low-income countries. Studies from the Bandim Health Project in Guinea-Bissau, and elsewhere, have revealed, that the live measles and oral polio vaccines have beneficial non-specific effects, i.e. effects on child morbidity and mortality unrelated to prevention of the targeted diseases. The campaigns are presumed to be most beneficial for children not reached by routine vaccination programs, as they are not already protected. However, studies show that prior routine or campaign vaccination may boost resistance against unrelated infections. If we phase out measles and oral polio campaigns after eradicating their target infections without considering the impact on child survival, the drastic decline in child mortality since 1990 could change direction. We will conduct the first cluster randomized controlled trial to evaluate the effect of measles and oral polio campaigns on general child morbidity and mortality via the Bandim Health Project. Bandim Health Project runs a Health and Demographic Surveillance System in Guinea-Bissau since 1978 and assesses child health interventions' real-life effects, via continuous registration of all interventions given to all children, and follow-up of individuals. We will conduct the trials in rural Guinea-Bissau monitoring all nine health regions. The hypotheses are: RECAMP-MV: Measles vaccination campaign in Guinea-Bissau reduce morbidity and mortality among children between 9 and 59 months of age by 80% during the subsequent 18 months in a context of limited measles infection. RECAMP-OPV: Oral polio vaccination campaigns in Guinea-Bissau reduce morbidity and mortality among children between 0 and 8 months of age by 25% during the subsequent 12 months in a context with no polio infection. Originally, the trials were meant to be implemented in 182 clusters, enrolling 21000 children. Following revised sample size calculations and discussions with the Data Safety and Monitoring Board, the number of clusters were increased to 222 and the planned number of enrolments increased from 21,000 to 28,000 (RECAMP-MV: 18000, RECAMP-OPV: 10000). To explore the hypothesis that at least part of the beneficial non-specific effects of OPV is driven by changes in the gut and/or respiratory microbiome, we will collect microbiome samples in a sub-group: A nasal swab and a rectal swab will be collected from 50 infants allocated to the intervention group, and 50 infants allocated to the control group. Two sample will be collected for each infant one when recruited for RECAMP-OPV and a second two months later.

NCT ID: NCT03381378 Completed - Children Clinical Trials

Vitamin D and Hand Grip Strength at 5 Years in Odense Child Cohort

Start date: January 4, 2016
Phase: N/A
Study type: Observational

This study will encompass an analysis of an eventual association between vitamin D status (maternal during pregnancy, at birth or at 5 years) and hand grip strength at 5 years in children from Odense Child Cohort. Odense Child Cohort is a large-scale, prospective, population-based, follow-up study. Mothers and their children born from January 2010 to December 2012 and resident in the Municipality of Odense, Denmark, are followed from early pregnancy up to adulthood. Data is obtained from questionnaires and medical records and venous blood samples were drawn and stored at a biological bank. Low muscle strength in children has been linked to adiposity, cardiovascular disease and metabolic risk factors and low muscle strength in adolescence has been shown to be a risk factor of early adulthood mortality. There are not many studies on muscle strength in small children. There is some evidence of vitamin D concentrations in the blood having a positive correlation to upper body muscle strength in adolescent girls. Hypovitaminosis D defined as serum 25-hydroxyvitamin D <50nmol/L was evident in 27,8% of the pregnant women and 47,7% of the new-born children in Odense Child Cohort. Animal studies have shown an effect of vitamin D on regulation of muscle function and development. Studies on humans adults have shown that vitamin D deficiency can lead to myopathy. Myopathy in children as a result of hypovitaminosis D is not well-studied. Given the high prevalence of hypovitaminosis D, mild or severe vitamin D-associated myopathy may be prevalent in preschool children. The objectives of this study are 1) to create reference values and determine predictors of hand grip strength at five years, 2) to analyze the associations between vitamin D at different time points and hand grip strength at 5 years.
