Filter by:Background: Sickle cell disease (SCD) is a chronic illness. It affects about 100,000 people in the United States. People with SCD have red blood cells that are sickle-shaped and impaired in their function. This results in a lifetime of complications that affect every organ system. People with SCD also are at greater risk for respiratory infections and lung problems. Researchers want to study how this population s stress, anxiety, fear, pain, sleep, and health care use are being affected by the COVID-19 pandemic. Objective: To study the extent and impact of life changes induced by the COVID-19 pandemic on people living with SCD in the U.S. Eligibility: People age 18 and older with SCD who live in the U.S. Design: Participants will complete a survey online. The questions will focus on the following: Medical history Mental and physical health Demographics Stress Resilience Health care use COVID-19 Beliefs about medical mistrust and participation in research. At the end of the survey, participants will be asked if they would like to take the survey again in the future. If they reply "yes," then they will be contacted by the study team in 6-9 months to take the survey again. They may complete the survey again in 6-8 months, 12-15 months, and 18-21 months. The survey should take less than 40 minutes to complete. Participants' data will be coded to protect their privacy. The coded data may be shared with other researchers.
The actual worldwide context (disease outbreak, confinements instaured in many countries) is a stressful factor for many people. It can have consequences on mental health : separation from loved ones, loss of freedom, uncertainty about infection status, boredom. Patients with mental disorders are especially vulnerable. On march 17th, the french government ordonned a national confinement to slow the progression of the COVID-19 outbreak, for 15 days at first then renewed several times. This situation has led to a reorganization of care as requested on March 22nd, 2020 in the recommendations applicable to the organization of care in psychiatric services : priority to telephone contacts and teleconsultation by multiplying contacts and assessments. By the time the reorganization of care became operational, the most vulnerable patients may have experienced a decompensation of their disease. It is important to know if the COVID-19 outbreak combined with the confinement increased the number of unvoluntary commitment the month after the announce of the confinement. This could help us understand which patients are more vulnerable is this context, and improve our organization (ambulatory and hospitalization care) if this situation occurs again.
The purpose of this study is to assess the safety and efficiency of an assembled modified mask in protecting health care workers against Coronavirus in case of any personal protective equipment shortage. At least 20 healthy participants will be recruited to try the modified mask. The modified masks will be made from masks that are already available as well as filters available in the pulmonary department at the Oklahoma City VA Health Care System
The classic myeloproliferative neoplasias (MNP), including polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (PMF) or secondary to PV or ET, are among the most frequent of malignant hemopathies, with overall prevalence estimated at around 10,000 patients followed in France. Due to the median age of patients around 65, the frequency of cardiovascular complications of these thrombogenic diseases and the impact of cytoreductive treatments on immune cells, these patients are considered to be at risk of developing forms severe of COVID-19. This study will assess the impact of MNPs on the risk of developing a severe form of COVID-19, identify new risk factors linked to the disease as well as the impact of treatments for MNPs according to their pharmacological class.
In response to the coronavirus disease 2019 (covid-19) outbreak, the home confinement of the population ordered by governments in many countries raise questions about its impact on individuals' physical and mental health in the short and longer term. In children, reduced physical activity, changes in lifestyle, disturbances in sleep patterns, lack of in-person contact with peers, poor or inadequate understanding of health risks may be risk factors of anxiety, stress, fatigue, sleep disorders. These problematic effects could be modulated by social factors (housing in urban or rural areas, availability of personal space at home, parenting stress, etc.).
This is a phase 3 clinical trial, randomized, single-center, opened, controlled, to evaluate efficacy and safety of early administration of colchicines in patients older than 60 years, with high risk of pulmonary complications due to coronavirus SARS-CoV2 (COVID-19). An approximately number of 954 subjects meeting all inclusion and none exclusion criteria will be randomized either to receive colchicines or symptomatic treatment with paracetamol during 21 days.
Since the start of this epidemic, numerous clinical and fundamental studies have been conducted to best adapt the individual management of COVID-19 cases [1-6]. In parallel with this work, it is necessary to better understand the characteristics of the epidemic in the general population but also in the population working in healthcare settings more exposed to SARS-CoV-2. Seroprevalence studies are therefore particularly useful in order to understand the collective immunization rate and the factors that can explain this immunization.
Hong Kong public healthcare system is facing tremendous pressure under the COVID-19 pandemic. As the virus spread in Hong Kong, Hong Kong Sanatorium & Hospital (HKSH) is one of the first private hospitals which immediately provide reliable and rapid COVID-19 test -- Reverse Transcription Polymerase Chain Reaction (RT-PCR). Early provision of the RT-PCR screening test for COVID-19 not only facilitates identification of COVID-19 but also contains the spread of the virus in the community and frontline medical staff. Since description of role of private hospital in Hong Kong amid COVID-19 pandemic is lacking, this study will describe COVID-19 screening algorithm and methodology. A retrospective analysis on clinical characteristics, laboratory findings as well as outcome of patients who underwent COVID-19 test in HKSH is also performed.
This study intends to find out how a cloth mask may impact exercise capacity, to provide guidance for exercisers to adjust their expectations and training accordingly. The investigators plan to asses exercise capacity through estimated peak oxygen consumption (eVO2peak), oxygen saturation and level of perceived exertion during treadmill based exercise while wearing a cloth mask compared to exercising without a cloth mask. The potential significance of this study is to determine if subjects can exercise safely and if their exercise training needs to be adjusted while following the current recommendations of wearing a cloth mask in public. The degree of airflow limitation experienced will depend on the type and fit of the mask being worn, and inadequeate airflow could possibly result in CO2 re-breathing if all air was not fully discharged from the mask with each breath. This re-breathing of CO2 could potentially limit the workload leading to a detriment in performance, and increase in adverse symptoms such as dizziness, lightheadedness, chest pain or shortness of breath that does not improve with rest.
Because of the physiological changes inherent in pregnancy, pregnant women with lower respiratory tract infections often have more worrisome outcomes compared to non-pregnant individuals, including a higher rate of hospital and intensive care unit admissions.
