Filter by:This study aims to compare the effectiveness of preoperative single dose of levofloxacin with postoperative levofloxacin for three days on the incidence of urinary tract infections (UTI) after urodynamic examination.
The objective of this study is to determine if early high volume intravenous fluid administration (hyperhydration) may be effective in mitigating or preventing complications of shiga toxin-producing E. coli (STEC) infection in children and adolescents when compared with traditional approaches (conservative fluid management).
This is an open-label, multicenter, randomized phase 1 study to evaluate the safety and immunogenicity of BG505 MD39.3, BG505 MD39.3 gp151, and BG505 MD39.3 gp151 CD4KO HIV trimer mRNA. These trimers are based on the BG505 MD39 native-like trimer reported in Steichen et al. Immunity 2016. The primary hypothesis is that the BG505 MD39.3 soluble and membrane-bound trimer mRNA vaccines will be safe and well-tolerated among HIV-uninfected individuals and will elicit autologous neutralizing antibodies.
The purpose of this study is to evaluate the pharmacokinetics of a single dose of intravenous or oral omadacycline in children and adolescents with suspected or confirmed bacterial infections.

The frequency of Chlamydia trachomatis and Neisseria gonorrhoeae coinfection can vary depending on their individual incidence and prevalence rates.Single-agent therapy with ceftriaxone is the preferred regimen for treatment of gonococcal infections. If an injectable cephalosporin is not available, cefixime is the only oral cephalosporin that can be used for gonococcal therapy. Doxycycline was recommended for presumptive treatment of chlamydia in nonpregnant individuals with gonococcal infection. The study is conducted to evaluate the effectiveness of two regimens in combination with doxycycline with cefixime or ceftriaxone.
Of the 1,900,000 Canadians who have been infected by COVID-19, 8 to 15% will continue to experience COVID-19 related symptoms well after 12 weeks. The persistence of such symptoms is now defined as "long COVID" syndrome. Current evidence does not provide a clear understanding of the physical and cognitive impairments and functional limitations that persons with long COVID present. The objectives of this project are to describe the physical and cognitive impairments and functional limitations experienced by people with long COVID and compare the evolution over 6 months of people from three separate groups: a group of people with long COVID (long COVID Group), another group of people who contracted COVID-19 but did not experience persistent symptoms (acute COVID Group), and a group of people who did not contract COVID-19 (Control Group). One hundred and twenty adults in each of the three groups will be recruited and will take part in three evaluations within 6 months (baseline and 3 and 6 months after baseline). At baseline, all participants will complete questionnaires on sociodemographics, COVID symptomatology and comorbidity, and self-reported questionnaires on quality of life, functional status, sleep, pain-related disabilities, anxiety, depression, fatigue and cognitive function. Then, physical and cognitive tests will be performed in a laboratory to provide complementary results on impairments and functional limitations. Finally, participants will wear a fitness tracker watch to monitor their activity and sleep for 7 days. The participants will complete the same measures (questionnaires, lab measures, fitness tracker watch) at 3 and 6 months after baseline evaluations. This project will lead to a better understanding of the impairments/limitations experienced following COVID-19. Hence, these results will allow to identify the interventions needed by the population and ensure these are offered through effective healthcare pathways.
Combination antiretroviral therapy (cART) blocks intracellular human immunodeficiency virus (HIV) replication in CD4+ T-lymphocytes, but fails to eliminate latent HIV infected CD4+ T-lymphocytes. About 7 (range <1-100) in 106 of these cells are latently infected and can cause reactivation of proviral HIV when cART is stopped. These latently infected cells form the reservoir and must be targeted in order to cure HIV. We would like to further investigate this reservoir and assess potential interventions to eradicate it. One promising option is to further study the influence of HIV latency disruptors (latency reversing agents, LRA) on the HIV infected reservoir. These agents are used in shock and kill strategies that disrupt latency by LRA followed by the selective (induced) killing of the reservoir cell due to viro-pathogenic effects. For accurate assessment of the reservoir and potential cure strategies, including the impact of LRA on the reservoir, a large reservoir and sufficient cells for analysis are desirable. Our understanding on the reservoir comes from in vitro lymphocyte models and early ex vivo studies. Additional studies of patients with different clinical phenotypes including untreated versus treated versus the rare individuals that control HIV spontaneously are increasingly relevant to the field. Especially this last category represent biological examples of viral control without cART and are useful to study the factors that set them apart from those that need treatment for their HIV. This study aims to deepen our understanding of the HIV reservoir and cure strategies, foremost, shock and kill strategies. We will do this by setting up a durable ex vivo platform for HIV reservoir and cure studies of which the samples can be used for hypothesis generation for in-vivo studies.

Lung allograft recipients have a higher burden of influenza disease and greater associated morbidity and mortality compared with healthy controls. Induction and early maintenance immunosuppression is thought to impair immunogenicity to standard dose inactivated influenza vaccine. This early post-transplant period is when immunity is most desirable, since influenza disease during this time frame is associated with adverse consequences. Thus, strategies to reduce severe influenza disease in this highly susceptible population are critical. No trials in lung transplant recipients have evaluated two doses of HD-IIV within the same influenza season as a strategy to improve immunogenicity and durability of influenza prevention. Furthermore, no influenza vaccine trials have focused on enrollment of subjects at early post-transplant timepoints. Very few studies have been performed in solely lung allograft recipients. Immunosuppression intensity is highest in lung patients, thereby limiting comparisons to recipients of heart, liver, and kidney transplants. Therefore, studies to assess both HD-IIV and two-dose strategies in the same influenza season in post-lung transplant recipients are greatly needed. The central hypothesis of our proposal is that lung allograft recipients who are 1-35 months post-transplant and receiving two doses of HD-quadrivalent inactivated influenza vaccine (QIV) will have higher HAI geometric mean titers (GMT) to influenza antigens compared to those receiving two doses of SD-QIV. To test this hypothesis and address the above critical knowledge gaps, we propose to conduct a phase II, multi-center, randomized, double-blind, controlled immunogenicity and safety trial comparing the administration of two doses of HD-QIV to two doses of SD-QIV in lung allograft recipients 1-35 months post-transplant. The results of this clinical trial will address significant knowledge gaps regarding influenza vaccine strategies (e.g., one vs. two doses and HD-QIV vs. SD-QIV) and immune responses in lung transplant recipients and will guide vaccine recommendations during the post-transplant period.
Pyogenic liver abscess is one of the most common visceral abscesses, its incidence is increasing worldwide. According to the previous literature, the mortality rate of pyogenic liver abscess is as high as 31% and become a serious social health problem. However, the data of prospective observational real-world studies are scarce and no relevant research of the liver histological change has been reported, so the long-term prognosis and the risk factors for pyogenic liver abscess are still unknown. Patients will be followed up prospectively for a period of 2 years and observed clinical prognosis (all-cause mortality, the recurrence rate, and the rehospitalization rate). The investigators will investigate the predictive value of clinical risk factors for clinical prognosis and establish clinical prediction models to predict the long-term prognosis of pyogenic liver abscesses.
