Until now there is no vaccine or reliable treatment for the COVID-19 pandemic. The fundamental mechanisms of non-invasive low-level laser in photobiomodulation (PBM) and photodynamic therapy is to stimulate the mitochondrial respiratory chain where a transient release of non-cytotoxic levels of reactive oxygen species (ROS) will lead to positive modulation of the immune response. As previous studies mentioned that the most important strategy for COVID-19 management is oxygenation and faster rehabilitation of the damaged tissue, antiviral effects, and, finally, reduction or controlling the cytokine storm by reducing inflammatory agents. PBM may be used as adjuvant therapy or even an alternative therapy in all these mechanisms without side effects and drug interactions. Objectives The objective of this clinical trial is to use the photobiomodulation therapy (PBMT), and photodynamic therapy as adjuvant therapy or even an alternative therapy for Covide-19. Patients and methods A randomized controlled study will be conducted on 60 patients of positive COVID 19. The patients will be divided into 3 equal groups. Group, I will receive a low-level laser (diode laser 980nm) from laser watch for 30 minutes, 20 J for 3 to 5 days, and laser acupuncture. Group 2 will be treated with photodynamic therapy by injecting the methylene blue as a photosensitizer and irradiated with laser watch (diode laser 670 nm). Group 3 will serve as a control. Evaluation methods will include laboratory investigations and CT chest.
Cardiovascular involvement in coronavirus disease-2019 (COVID-19) encompasses a wide range of vascular and myocardial pathologies, including both acute and long-term sequelae. The MIIC-MI study aims to investigate mechanisms of cardiac injury in COVID-19 using multi-modality imaging and immunophenotyping to better understand the link with adverse patient outcomes.
This is an open-label, multicenter, parallel-group, randomized, phase III trial that evaluates the efficacy and safety of hydroxychloroquine and favipiravir in the treatment of patients with possible or confirmed COVID-19 observed within the last 5 days. 1000 patients will be randomized in 2:1:2:2:2:1 ratio and divided into six groups.
Since the outbreak of COVID-19 hit Spain in March 2020, most of the elective surgeries have been canceled everywhere. As soon as the epidemiology phase of the pandemic changed and the restrictions have been eased, different protocols have been put in place to screen patients for SARS-CoV-2 before surgery in order to reduce the spreading of the disease in hospitalized patients. To the best of the current state of knowledge, no recommendations or protocols have been established to guide surgeons in dealing with patients developing unspecific symptoms after surgeries, which could sign either of a post-op complication or COVID-19. The investigators have developed an enhanced pre and post-surgical protocol both to screen patients for COVID-19 before surgery and to promptly identify those patients suspicious for the viral infection during the post-op.
Coronavirus disease 2019 (COVID-19) and associated emergency measures (EM) have dramatically impacted the lives of children/adolescents (children) and families. The closure of schools, social and recreational activities, and modifications to work environments has led to significant changes in the way children and families are working, living and socializing. Although the impact on the mental health of children and families has not been well researched, it is anticipated that already stressed children and families with pre-COVID-19 mental health challenges are at significant risk for deterioration in their mental health. As such, the implementation, and evaluation (specifically: feasibility, acceptability and barriers) of virtual-care interventions to alleviate child and family anxiety and enhance family functioning are critical. Virtual-care also optimizes health equity initiatives in reducing social, economic and environmental barriers to services that can improve or maintain mental health (WHO, 2017; MOHLTC, 2018). The current study will evaluate an adapted virtual-care cognitive behavioural therapy (CBT) program for children with anxiety (VC-CBT). CBT has a strong evidence-base in treating children with anxiety disorders (Higa-McMillan, Francis, Rith-Najarian, and Chorpita, 2016; Seligman and Ollendick, 2011), with increasing evidence supporting the efficacy of virtual-care CBT for childhood anxiety disorders (Carpenter, Pincus, Furr, and Comer, 2018; Slone, Reese, and McClellan, 2012). This study aims to evaluate the feasibility, participation barriers related to social determinants of health (SDH) and acceptability of this virtual-care intervention in addressing mental health challenges associated with the COVID-19 pandemic and ensuing EM in the immediate time-period. Early evaluation of this virtual-care intervention will enable future scale-up of this intervention during the post-pandemic recovery time-period and during subsequent COVID-19 waves, if necessary.
The COVID-19 pandemic affects eating habits, diet quality and physical activity differently among individuals; it is unclear how these behaviours will evolve as the pandemic continues. In this observational study, dietary intake will be frequently collected using an artificial intelligence (AI)-enhanced mobile application combined with real-time analysis, and lifestyle behaviours from online questionnaires, to provide timely, relevant data for public health decision making.
The Açaí trial will be testing if the açaí berry extract, a safe natural product with anti-inflammatory properties, can be used as a treatment option in adult patients with COVID-19 in the community.
To build simple and reliable predictive scores for intensive care admissions and deaths in COVID19 patients. These scores adhere to the TRIPOD (transparent reporting of a multivariable prediction model for individual prognosis or diagnosis) reporting guidelines. The outcomes of the study are (i) admission in the Intensive Care Unit admission and (ii) death. All patients admitted in the Emergency Department with a positive reverse transcription‐polymerase chain reaction SARS-COV2 test were included in the study. Routine clinical and laboratory data were collected at their admission and during their stay. Chest X-Rays and CT-Scans were performed and analyzed by a senior radiologist. Generalized Linear Models using a binomial distribution with a logit link function (R software version X) were used to develop predictive scores for (i) admission to ICU among emergency ward patients; (ii) death among ICU patients. A first panel of Number Models with the highest AIC (BIC) was preselected. Ten-fold cross-validation was then used to estimate the out-of-sample prediction error among these preselected models. The one with the smallest prediction error was in the end singled out .
