Filter by:Introduction: The pregnancy brings about physiological and hormonal modifications which cause sleep disorder. The sleeplessness, snoring and a bad sleepquality are frequent during the pregnancy. Also a limited breathing airflow happens very often during the pregnancy. The limited airflow causes micro-awakenings that enter in the frame of the high resistances airways syndrome. To our knowledge there is no study about the outcome of micro-awakenings at pregnant women. Objectives: To compare the prevalence of the high resistances airways syndrome (RERA) in pregnant woman with or without gestational diabetes Methods : It is a monocentrical prospective study at pregnant women after the 30th amenorrhea week who consul the gynecologie and obstetrics department of the CHU NORD in Marseille. We are going to compare the breathing disorder during sleep of a control group with a group of women with gestational diabetes. A polysomnograph will be run at the included patients' home. Expected results : The physiological and hormonal modifications during the pregnancy could favor nocturnal sleep events (snoring, SAHOS and RERA) and its complications as gravidic HPN And gestational diabetes cause maternal and fœtal and morbidity and mortality. We put the hypothesis that limited airflow in association with micro-awakenings in the RERA have a negative impact on the glucose metabolism and favor the gestational diabetes.
Introduction: Smoking is a major avoidable cause of ill-health and premature death. Treatments that help patients successfully quit smoking have an important effect on health and life expectancy. Varenicline is a medication that can help smokers successfully quit smoking. However, there are concerns that it may cause adverse effects, such as increase in the occurrence of depression, self-harm and suicide and cardiovascular disease. In this study the investigators aim to examine the effects of varenicline versus other smoking cessation pharmacotherapies on smoking cessation, health service use, all-cause and cause-specific mortality and physical and mental health conditions. Methods: In this project the investigators will investigate the effects of varenicline compared to nicotine replacement therapies on: (1) long-term smoking cessation and whether these effects differ by area level deprivation; and (2) the following clinically-important outcomes: rate of general practice and hospital attendance; all-cause mortality and death due to diseases of the respiratory system and cardiovascular disease; and a primary care diagnosis of respiratory illness, myocardial infarction or depression and anxiety. The study is based on a cohort of patients prescribed these smoking cessation medications from the Clinical Practice Research Datalink (CPRD). The investigators will use three methods to overcome confounding: multivariable adjusted Cox regression, propensity score matched Cox regression, and instrumental variable regression. The total expected sample size for analysis will be at least 180 000. Follow-up will end with the earliest of either an 'event' or censoring due to the end of registration or death. Ethics and dissemination: Ethics approval was not required for this study. This project has been approved by the CPRD's Independent Scientific Advisory Committee (ISAC). The investigators will disseminate the findings via publications in international peer-reviewed journals and presentations at international conferences.
The BREATHE (Behavioral Research of Environment and Air Pollution Through Education) study is a pilot randomized control trial comparing the efficacy of a classroom-based intervention to no intervention in helping middle-school students understand and make behavioral decisions about air pollution. This study is designed to evaluate the effectiveness of the classroom-based intervention on knowledge of air pollution, understanding of air pollution sources, and behavioral choices made to reduce both contributions to air pollution and personal exposure to air pollution. It has been well established that pollution is a racial and economic issue. Low-income areas with populations of predominantly people of color tend to be those with the highest rates of pollution and the largest particulate exposure. Creation of and exposure to this pollution is a key issue for the health of inhabitants of these areas, and of those in the broader surrounding areas. By developing, and assessing the effectiveness of, the investigators hope that the BREATHE study will give the investigators insights into how to better combat this higher exposure and reduce the health risks for those in high pollution areas. The study will take place in 4 visits over a period of 12 months. The hypothesis is that the classroom-based intervention will be effective in leading to behaviors that will reduce exposure to air pollution.
The 2009 flu pandemic is a global outbreak of a new strain of influenza A virus subtype H1N1, commonly known as swine flu, that was first identified in April 2009. Large-scale immunization is an essential approach of controlling the pandemic.Vaccines are now becoming available for protection against pandemic influenza A(H1N1) 2009 infection in some countries.In response to the pandemic, novel vaccines against the virus strain A/California/07/2009(H1N1) have been developed and recently were approved for vaccination among specific populations in China. However, the safety and effectiveness of the vaccines is of prime concern to the authorities and the public.This report details the findings of a observational clinical trial of the safety and immunogenicity of a influenza A (H1N1)2009 monovalent vaccine. The virus of Swine Flu H1N1 that outbroke in 2009 is sensitive to neuraminidase inhibitors (Oseltamivir, zanamivir and peramivir) but have drug resistant to adamantanamine derivatives (amantadine and Flumadine), therefore neuraminidase inhibitors are recommended for antiviral therapy against Swine Flu H1N1, effect of which is evidence by the data that such drugs do modify the symptoms and decrease the death rate of H1N1 in America and Mexico. However, clinically, the investigators have encountered that this virus can infect resistant strains of Oseltamivir, which urges for a more effective treatment plan. In view of above situations, seeking for an effective measures against H1N1 flu should be a top priority and will benefit human life and economy globally. This Topic will take the classic strategy of passive immunity to perform basic and clinical researches on applying blood fix to treat critical H1N1 patients and collect blood of healthy persons who are inoculated with specific H1N1 vaccines to cure critical H1N1 patients.
