Children infected with COVID-19 are mostly asymptomatic. There is a dearth of data on the epidemiology of COVID-19 in the pediatric population. This is a prospective observational clinical study of pediatric surgical patients. COVID-19 rapid antigen testing will be performed on pediatric patients. Read Less

Chronic pain may cause psychological or behavioral problems. Chronic pain patients occasionally harass the pain care providers. The COVID-19 pandemic caused major stress for the general population. Quantitative and qualitative analysis of prospective electronic and clinic diary data. Evaluation of incidents of clinic staff harassment; caused by patients, before and during COVID pandemic. Analysis of causative factors, incident outcome and lessons learned. Read Less

Chronic pain is associated with mental disorders, and some patients have behavioral issues. Some patients may sexually or racially harass pain clinic staff. Healthcare staff do not usually report sexual or racial harassment perpetrated by patients. Quantitative and qualitative analysis of prospective electronic and clinic diary data. Evaluation of incidents of sexual and racial harassment of clinic staff; perpetrated by patients. Analysis of causative factors, incident outcome, system factors and lessons learned. Read Less

Caudal analgesia is an effective intervention for lumbosacral pain. Some chronic pain patients take anticoagulants for vasculopathy treatment. Anticoagulation limits the use of caudal analgesia because of the risk of epidural bleeding. Caudal analgesia may be safe and effective in anticoagulated chronic pain patients. Quantitative analysis of prospective clinical data. Evaluation of caudal analgesia efficacy and safety in anticoagulated chronic pain patients. Analysis of outcome, and complications. Read Less

Most chronic pain patients have mood disorders. The mood disorders may improve with better analgesia produced by Ketamine injections. A prospective study of patients undergoing interventional pain therapy using Ketamine injections. Pre-injection and post-injection patient data is collected. Pain is measured using numeric pain rating scale, and change in pain score by 2-points is considered significant. Sleep is measured using Likert sleep scale, and change in sleep score by 2-points is considered significant. Anxiety is measured using general anxiety disorder (GAD-7) scale, and change in anxiety score by 4-points is considered significant. Depression is measured using patient health questionnaire (PHQ-9), and change in depression score by 5-points is considered significant. Read Less

In this double-blind phase II randomized controlled trial, patients with lung cancer or ≤2 oligometastatic pulmonary lesions and a concomitant diagnosis of ILD who are planned for radical Radiation Therapy (RT) will be randomized using a 2 x 2 factorial design to oral N-acetylcysteine (NAC) versus placebo, and also to short course corticosteroids versus placebo.

Chronic pain is associated with psychological disorders; which may affect a patient's socioeconomic, legal, domestic, and employment situations. This prospective observational study evaluates the impact of pain management on patients' health, social, economic, and employment status. It explores the impact of pain clinic services on patients' mental health, family health, public health, road safety, addiction situation, public safety, injury rehabilitation and employment situation.

Pelvic pain is under-reported in healthy adults. Many patients with pelvic pain under-estimate the problem. Chronic pelvic pain can be managed properly, if diagnosed promptly. This is a quantitative analysis of prospective clinical data. It evaluates the management of pelvic pain in a cohort population, and analyzes the treatment outcome. Read Less

Chronic pain is associated with injuries and disabilities. This prospective observational study explores the injury or disability claims made by chronic pain patients. It evaluates the socio-demographics of the patient population. It explores the impact of pain clinic services on the patients' injury rehabilitation, insurance claim outcome, and socioeconomic situation. Read Less

This study compares aerobic exercise training performed before breakfast (i.e., in the fasted state) to similar training performed after breakfast in people with type 1 diabetes. Training will take place over 12 weeks. Read Less

The creation and distribution of child sexual abuse material (CSAM) is a large-scale global problem. CSAM is sometimes referred to as child pornography. It includes images, videos, live-streaming, and any other material that depicts sexual acts with a child or adolescent (i.e., a person under the age of 18). It also includes material that shows a child or adolescent in a sexually suggestive or explicit manner partially clothed, or nude, and can include material that does or does not illustrate sexual activity. CSAM use is a problem that continues to drastically increase in size despite the numerous political, police, and technological initiatives that have been put forth as solutions. Previous research also suggests that many active CSAM users desire help to stop their use, but have experienced difficulties finding support that is anonymous. Thus, there is a great need for anonymous intervention programs that assist active and at-risk CSAM users in developing skills to manage their thoughts, feelings, and behaviours related to CSAM. ReDirection is a free, anonymous, online, self-guided, cognitive behavioural therapy (CBT)-based program for individuals concerned about their use or risk to use CSAM. The treatment program is based on many years of clinical experience working with patients who have committed sexual offences, and the results of several previous research projects. This study will implement a scientifically rigorous design (a three-armed randomized waitlist-controlled trial) to evaluate two versions of this intervention (ReDirection 1.0 and ReDirection 2.0). The primary difference between the two versions of ReDirection is the length of the program and whether it includes the option for asynchronous messaging with a ReDirection specialist. The study design compares ReDirection 1.0 and ReDirection 2.0 with a waitlist control group. Participants in the waitlist control will wait six weeks before starting active treatment. While on the waitlist, participants will respond to questions about ongoing about sexual urges and behaviours. Participants will be recruited directly from the ReDirection website, where they will be directed to a secure platform designed specifically for clinical trials of internet-mediated CBT. This platform is called Iterapi. Potential participants learn about the ReDirection program through advertisements on both the "Clearnet" and "Darknet." All trial activities, including participant registration, random assignment, intervention, and evaluation will be conducted via Iterapi. Treatment includes five-to-six modules over five-to-six weeks and the content includes CBT-based psychoeducation and exercises that aim to help participants gain greater understanding of, and skills to manage risky sexual thoughts, feelings, and behaviours.

The DEFEND trial will be the world's first clinical trial to study the effectiveness of Paxlovid or Veklury in the prevention of cardiovascular post-acute sequelae of SARS-CoV-2 among hospitalized adults. Additionally, this pilot study will inform the design and conduct of a future full-scale multi-centre trial by testing the feasibility and accuracy of this study design. Read Less
