NCT ID: NCT04486456 Not yet recruiting - Prevalence Clinical Trials

Epidemiological Study on Anemia and Iron Deficiency in Pregnancy in Medical Institutions in Some Areas of China

Start date: August 2020
Phase:
Study type: Observational

The purpose of this study is to describe the prevalence of anemia and iron deficiency in pregnancy through a multi-center, prospective follow-up study . To explore the influence factors of anemia and iron deficiency in pregnancy; to explore the influence of anemia and iron deficiency in pregnancy on maternal and fetal outcomes.

NCT ID: NCT04448769 Completed - Clinical trials for Coronavirus Infection

Epidemiological Study of Seroprevalence Against the SARS-CoV-2 Virus (COVID-19)

COVAL-NANCY
Start date: June 26, 2020
Phase: N/A
Study type: Interventional

In order to inform the public decision on the containment strategy and knowledge of the intensity of the epidemic during post-containment, estimates of the share of the population infected with the SARS-CoV-2 virus responsible for COVID-19 disease at the territorial level are needed as soon as possible. The aim of the study is to estimate the prevalence of positive anti-SARS-CoV-2 serologies by detection of IgT-total antibodies (IgM/IgA/IgG) in the general population of the Grand Nancy Metropolitan area. A study of seroprevalence and symptom collection, or absence of symptoms, on a cluster (household) sample of the Grand Nancy Metropolitan population randomly selected will be conducted. The target population consists of all the inhabitants of the Grand Nancy Metropolitan area, from which a sample is drawn from the electoral lists (households) in a random manner to ensure representativeness. In order to ultimately include 2000 people in the study

NCT ID: NCT04412746 Recruiting - Diabetes Mellitus Clinical Trials

Covid-19 and Diabetes in West of Algeria

COVIDIAB-13
Start date: April 1, 2020
Phase:
Study type: Observational

By Jan 7, 2020, Chinese scientists had isolated a novel coronavirus, from patients with virus-infected pneumonia. The WHO designated later this virus as COVID-19 (coronavirus disease 2019). This exponential pandemic coronavirus infection is responsible for severe forms in 15 to 20%, for critical ill requiring ventilation in 5% and for mortality in 2%. Algeria was part of the 13 top priority countries identified by WHO based on their direct links and volume of travel to the infected provinces in China. It is known that some predisposing conditions lead to a worse outcome with coronavirus. In China, the overall case-fatality rate was 2.3%, but was higher in patients with diabetes (7.3%). In Italy, the most common comorbidities associated with death from COVID-19 were hypertension (73.8%) and diabetes (33.9%). The US Centers for Disease Control and Prevention suggests diabetes is the most common comorbidity in COVID-19 cases. In the largest cohort NHS England study, death from COVID-19 was strongly associated with uncontrolled diabetes (after full adjustment, HR 2.36). The West Algerian CORODIAB-13 study aims is (1) to assess the prevalence of diabetes among hospitalized patients with Covid-19, (2) to describe the phenotypic characteristics of patients with diabetes, and (3) to identify the parameters specific to the diabetic which are associated with severe forms. In the future, this study will provide answers for two main questions 1. Why diabetics are more at risk of developing Covid-19 infection? 2. Why diabetics are at high risk of developing severe forms?
