Active clinical trials for "Congenital Abnormalities"

With the increasing number of COVID-19 infected patients, several studies reported that the liver is the most frequently affected organ after lung damage. The percentage of infected patients who had abnormal levels of transaminases (alanine aminotransferase (ALT) and aspartate aminotransferase (AST)) was about 14.8-53.1%. The elevation in serum bilirubin was mostly mild. Aims of work: To study liver function tests abnormalities in Egyptian patients who infected with COVID19 To evaluate if liver function test abnormalities are related to the severity of the Covid19.

Pulse oximetry screening (POS) for critical congenital heart diseases (CCHD) could identify 90% of these infants. However, this approach is not designed to detect cardiac defects without hypoxemia, especially congenital malformations of aorta (CMoA). More than 60% of CMoA was late diagnosed. Infants with CMoA were supposed to present with blood pressure (BP) gradient between four limbs. But a large sample size retrospective study of four-limb BP screening showed a negative result. The possible reason is that this study ran in population with a very low risk of CMoA. Whether four-limb BPs measurement could be used in infants with high risk of congenital malformation of aorta is still to be determined. The investigators retrospectively collected four-limb BPs, which was prospectively measured, in infants with high risk of CMoA. These data were divided into two groups, the discovery group and the validation group. The best cutoff of four-limb BP gradient was generated by Youden Index. The BP gradients by age were analyzed. Pre-operative hypotension and post-operative hypertension were also analyzed.

This is a prospective, observational, registration and follow-up study of women exposed to Betaseron® at the time of conception (i.e., any time from the first day of the last menstrual period) and/or during pregnancy. The Betaseron® Pregnancy Registry is designed to determine whether there is an increased risk or a pattern of birth defects in the offspring of women exposed to Betaseron® at conception and during pregnancy compared to rates from women in the general US population. Secondarily, the Registry will examine rates of spontaneous abortions and other negative pregnancy outcomes in this population. This study will be conducted in the United States (US). The Betaseron® Pregnancy Registry is sponsored by Bayer HealthCare Pharmaceuticals and is managed by the Post Approval & Strategic Services group at INC Research, LLC. The scientific conduct and analysis of the Registry will be overseen by an Independent Data Safety Monitoring Board (IDSMB) consisting of external specialists in teratology, epidemiology, maternal and fetal medicine, and neurology (external member details available upon request).

Each year in the United States, thousands of babies are born with heart defects. Women who take folic acid during pregnancy have a lower risk of giving birth to infants with heart defects, but the reason for this remains unknown. This study will examine the relationship between genes, nutrition, and the occurrence of heart defects in infants.

Background: Severe aplastic anemia (SAA) is a form of bone marrow failure. It usually results from a cytotoxic T cell attack on the marrow stem cell. Two treatments can be used for SAA. One is allogeneic hematopoietic stem cell transplant (HSCT). The other is immunosuppressive treatment (IST). In most cases, HSCT or IST works. But for some people, clonal evolution occurs after IST. One of the most common forms of clonal evolution is chromosome 7 abnormalities. These have a poor prognosis. HSCT can be used to treat them. Researchers do not know why clonal evolution happens. They want to look at data from past studies to learn more. Objective: To compare the data of people with SAA who developed chromosome 7 abnormalities between those who ultimately received HSCT versus those who received chemotherapy alone or supportive care. Eligibility: Adults and children with SAA who were enrolled on NHLBI protocol 12-H-0150, 06-H-0034, 03-H-0249, 03-H-0193, 00-H-0032, or 90-H-0146 Design: This study uses data from past studies. The participants in those studies have allowed their data to be used in future research. Researchers will review participants medical records. They will collect clinical data, such as notes, test results, and imaging scans. They will also collect the research data gathered as part of the original study. Researchers will enter the data into an in-house database. It is password protected. All data will be kept in secure network drives or in sites that comply with NIH security rules. Other studies may be added in the future.

In this observational follow-up study, patients with type III-IV head and face soft tissue deformities/defects following reconstructive surgeries will be asked to fill out 3 questionnaires, either through phone calls or video calls, in order to evaluate the post-operative outcomes such as morphological and functional recovery, quality of life and patients' return to the community.

Ultrasound scans during first trimester are more difficult than routine mid-trimester ultrasound scans. Practice guidelines for first trimester fetal ultrasound scans have been provided by the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) since 2013. Using this guidelines, different levels of proficiency operators might have equal ability to complete first trimester ultrasound scans.

Prospective, monocentric, single arm, observational PMCF - Study on the Performance and Safety of Double-Shank Titanium Ligation Clip in Urology (Prostatectomy and Nephrectomy)

Several drugs and chemotherapies seem to have an impact on the hematological system. This study investigates reports of hematological toxicities, including the International classification of disease ICD-10 for treatments in the World Health Organization (WHO) global Individual Case Safety Report (ICSR) database (VigiBase).

Difficult intubation is considered one of the most important obstacle increasing mortality in anesthesiology. Airway assessment tests are proceeded to overcome these difficulties in the pre-anesthetic evaluation. In this study, the Simplified Predictive Intubation Difficulty Score (SPIDS) and Thyromental Height Measurement (TMH) were chosen as primary methods to predict difficult intubation. The ear-nose-throat (ENT) and Plastic Surgery patients were planned to enroll this study to assess the effectiveness of these tests in predicting difficult intubation in Maltepe University Hospital and Sisli Hamidiye Etfal Governmental Hospital. The SPIDS of volunteers will be calculated according to their previous knowledge of difficult intubation, airway pathologies, head and neck movements, mouth opening, modified Mallampati test and thyromental distance. TMH value will be measured with ASIMETO depth device. Finally, the SPIDS and TMH values will be statistically compared to predict difficult intubation which is determined with difficult intubation score (IDS).
