Filter by:This cross-sectional observational study aims to determine the prevalence of Persistent COVID-19 in 282 individuals in Punta Arenas, Magallanes and Chilean Antarctic Region. Persistent COVID-19 is a complex array of symptoms that persist or emerge for more than 4 weeks beyond SARS-CoV-2 infection. Recent studies suggest that up to 80% of survivors may develop chronic multi-organ dysfunction due to persistent inflammation and immune dysregulation, making it an ongoing public health concern worldwide. The study aims to (1) describe and establish the frequency of physical and psychological signs and symptoms in adult patients who have tested positive for COVID-19, (2) identify individuals who meet the WHO case definition of Persistent COVID-19 in Chile, (3) explore risk factors associated with persistent COVID-19 to guide intervention strategies, and (4) explore inflammatory and molecular biomarkers associated with persistent COVID-19. The research project utilizes a stratified random sampling with a mixed-methods embedded design. In the first phase, individuals diagnosed with COVID-19 will be recruited and followed up to complete the study's sample universe. A sociodemographic survey, blood sampling (including complete blood count, biochemical profile, immunoglobulin mutational status analysis, and analysis of inflammatory biomarkers), and a battery of psychological tests will be administered. In the second phase, kinesiology studies and medical consultation and evaluation will be conducted to determine if individuals have Persistent COVID-19 and to derive them to the healthcare network. In the final follow-up phase, participants diagnosed with Persistent COVID-19 will be invited to undergo musculoskeletal and respiratory assessments to complete the diagnosis of symptoms associated with the pathology.
Persistent smell loss that can include diminished or distorted smell function is a common symptom of long COVID syndrome. There are limited treatment options for long COVID-related smell loss. This study aims to determine the efficacy of two at-home treatments, smell training and non-invasive trigeminal nerve stimulation. This study requires participants to conduct daily at-home treatment sessions, attend three in-person study visits at the MUSC Department of Psychiatry and Behavioral Sciences, and complete electronic questionnaires over the 12-week trial, and again at the six-month timepoint. Participants in this trial may benefit directly with an improvement in sense of smell. However, participation may also help society more generally, as this study will provide new information about long COVID-related smell loss and its treatment.
Dysautonomia in post-covid-19 condition appears to affect a significant number of patients, with reports raising the incidence up to 61%, having an overlap with myalgic encephalomyelitis/ chronic fatigue syndrome. Quality of life and daily function is significantly impacted and conservative management interventions, despite the lack of high quality evidence up to now, are needed to ameliorate disability. 50 adults with a dysautonomia post-covid-19 diagnosis based on the Ewing battery and a NASA lean test will be enrolled in a randomized single blinded controlled trial with a crossover design. Feasibility and lack of definite dysautonomia diagnosis will be the primary out-comes, while secondary outcomes will be health-related, clinical and cardiopulmonary exercise test indicators. Safety and acceptance will also be checked, primarily excluding participants with post exertional malaise. The Long-CoViD patients Causal Diagnosis and Rehabilitation study in patients with Dysautonomia (LoCoDiRE-Dys) study intervention will consist of an educational module, breathing retraining and an individualized exercise intervention of biweekly sessions for two months with regular assessment of both groups. LoCoDiRe- Dys aims to be the first post-covid-19 randomized study in people with dysautonomia offering a multimodal intervention both in diagnosis and management
The purpose of this study is to investigate if receiving doses of arginine (a protein in the body) will improve mitochondria function in children with COVID-19. The study will be performed in Children's Healthcare of Atlanta, Egleston campus. Patients will be randomized to receive one of three doses of arginine three times a day for five days or at discharge whichever comes first.
The goal of this clinical trial is to compare treatment with oral Paxlovid (nirmatrelvir/ritonavir) and placebo for acute COVID-19 as an intervention to prevent long-COVID (post-COVID-19 condition) in adults aged 18-64 years old. The main question it aims to answer is: Does treatment with Paxlovid for acute COVID-19 reduce the prevalence of long-COVID compared to placebo. Participants with acute COVID-19, documented with positive lateral flow test or PCR, within the last 5 days will be randomised to take either Paxlovid or placebo. All participants will receive standard of care in addition. Participants will respond to electronic questionnaires at 14 time points during follow-up. The primary outcome is presence of long-COVID symptoms at 3 months follow-up. Researchers will compare participants who received Paxlovid and placebo to see if Paxlovid treatment can prevent the occurrence of long-COVID.
At the end of 2019, cases of an unknown respiratory infection were reported in the city of Wuhan in China. It was determined that the cause of this infection was a new virus belonging to the coronavirus family, which was named SARS-CoV-2. After the virus spread worldwide, the World Health Organization (WHO) declared it a pandemic. The clinical picture and disease caused by the virus were named COVID-19 (1). According to the WHO's data on 29.01.2022, the number of cases worldwide has exceeded 365 million, and the number of deaths has exceeded 5 million (2). Fever, cough, fatigue, shortness of breath, myalgia, sore throat, and headache are the main symptoms of COVID-19. Less frequently, it can cause nausea, vomiting, and diarrhea. The disease has a broad spectrum ranging from mild illness to severe illness that can result in death (3). In a study analyzing the data of approximately 72,000 patients in China, it was reported that 81% of the patients had no lung involvement or minimal involvement, 14% had severe involvement, and 5% had respiratory failure, shock, or multiple organ failure (4). Attention is drawn to the long-term complications of COVID-19, such as myocarditis, heart failure, arrhythmia, dyspnea, oxygen dependence, impaired respiratory function tests, increased venous/arterial thromboembolism, decreased fitness, muscle and joint pain, increased anxiety-depression, post-traumatic stress disorder, and renal damage (5). It has been emphasized that patients who have recovered from COVID-19, especially older individuals and those with severe illness, are at risk of sarcopenia (7). It has been suggested that in patients who have recovered from COVID-19, direct viral damage, decreased physical activity level, and malnutrition result in decreased fitness and sarcopenia, which could be associated with increased morbidity in cancer surgeries (8). It is reported that postoperative complications and deaths are higher in active COVID-19 patients than in those who do not have active disease (9). In a multicenter study, it was stated that postoperative pulmonary complications were observed in half of the patients who had COVID-19 during the perioperative period, and this condition was associated with high mortality. Most of these patients are those who need emergency surgical interventions (10). According to studies in the literature, COVID-19 has multi-systemic effects, and some of these effects continue in the long term. It has been shown that the perioperative period with COVID-19 positivity is associated with higher pulmonary complications and mortality. It has been suggested that having had COVID-19 in the past may lead to worse postoperative outcomes. The studies in the literature were mostly conducted on patients who had surgery during the perioperative period while having COVID-19. Most of the patients required emergency surgical interventions. The effect of the patients' functional level on postoperative outcomes has not been examined. Our study focuses on the intraoperative and postoperative period of thoracic surgery patients who underwent surgery in the long term after COVID-19.
The coronavirus disease 2019 (COVID-19) has spread rapidly and caused a global pandemic, as defined by the WHO, within a short period of time. The prognostic of disease severity is still a challenge and early identification of risk factors to be involved in its progression is of high importance. The scoring of variables related to worse outcomes is key for a targeted and/or advanced protocol. Besides, the need for a predictive-wide model is mandatory for hospitalized unvaccinated patients to avoid any delay in the characterization of severe illness and the development of complications. The LUSZ COVID-19 Severity Index was developed as a predictive tool based on >100 risk factors/biomarkers, that could effectively identify high-risk patients and prevent mortality.
Although most infected people survive the infection, many have persistent sequelae or symptoms, which cause disability or decreased quality of life. The World Health Organization has called on countries to prioritize the rehabilitation of the consequences of COVID-19 in both the medium and long term, as this chronicity is expected to impact the health public and the economy in the coming years. RehabCOVID (also referred to as RehabNautilus) is born from the need to provide solutions to persistent cognitive impairment symptoms of people who have suffered from COVID-19. Thus, we will offer people with long COVID that accomplish inclusion/exclusion criteria to participate in a randomized clinical trial to evaluate the effectiveness of cognitive stimulation therapy combined with physical exercise and mindfulness. The current project is a single-blind randomized control study, where we will compare two combined interventions with a control group that will encompass different functional, structural, and biochemical changes and interactions in the brain. We will study the effects that this combined intervention produces in the brain. We expect to gain more insight into the specific neuroplasticity mechanisms of cognitive persistent COVID symptoms.
The aim of this study is to evaluate the efficiency and safety of immunoadsorption for the treatment of post-COVID syndrome (PCS). Efficacy will be measured (1) subjectively as an improvement of the score of questionnaires like the multidimensional fatigue inventory (MFI-20), Chalder fatigue scale, Bell-score, modified medical research council dyspnea scale (mMRC) and the Post-COVID functional scale (PCFS) and (2) objectively as an improvement in neurocognitive testing with the Montreal cognitive assessment (MoCA) and the improvement of the hand-grip strength. The study comprises 2 sub-studies, each with an identical design, including 40 participants each. The only difference between the sub-studies is the systems and adsorbers used for immunoadsorption and sham treatment. Participants with symptoms of PCS and a PCFS score of at least 2 will be included in each group. After excluding other causes of the symptoms and evaluating the baseline burden of symptoms, each participant will undergo 5 sessions of immunoadsorption with an immunoglobulin-binding adsorber and 5 sham treatments, or vice versa. The order of treatments (immunoadsorption first or sham first) will be randomized. Each participant will be blinded to the type of treatment they receive. An 8-week therapy-free period will separate the two treatment blocks. All examinations will be conducted before the first treatment, 2 weeks after the first treatment cycle, before the second treatment cycle, and 2 and 6 weeks after the second treatment cycle. The results of the study will inform future treatment strategies for PCS and will contribute to a better understanding of the pathophysiological insights behind the ongoing symptoms.
The COMET trial is an observational, cross-sectional study aimed at comparing the incidence of coronary microvascular dysfunction (CMD) in patients with stable angina who have a history of severe COVID-19 infection requiring mechanical ventilation (Group A) to those without a history of COVID-19 (Group B). A total of 102 participants will be recruited, with 51 patients in each group. Data will be collected on participants' demographic information, medical history, and COVID-19 infection history (confirmed by PCR test). CMD measurement will be performed using a pressure-temperature wire to assess the coronary flow reserve and index of microcirculatory resistance. In addition, information on participants' current medications will be gathered. The study will employ statistical analysis tools to compare CMD incidence between the two groups and assess the impact of various factors such as age and sex on CMD incidence. The results of the COMET trial will provide valuable insights into the effects of severe COVID-19 infection on CMD in patients with stable angina.
