Filter by:Currently there is little consensus regarding postoperative antibiotic prophylactic treatment and its effect on the postoperative infection rate after Cochlear implantation. The literature on this subject is contradictory, and very limited. The aim is to assess the impact of postoperative antibiotic treatment on post-operative infection rate, and thereby discuss if postoperative antibiotic treatment has any benefits in the preventing treatment against infectious complication.
Transumbilical laparoscopic appendectomy (TULA) is increasingly favored in the treatment of appendicitis within the realm of minimally invasive surgical approaches. This procedure offers advantages such as superior cosmetic outcomes and reduced postoperative pain. However, like all surgical interventions, it carries the inherent risk of surgical site infections (SSI), which pose significant challenges to patient health and healthcare systems by escalating treatment costs, prolonging recovery, and increasing morbidity rates. This study aims to evaluate the efficacy of the "glove finger method" in mitigating SSI risk in TULA. The rationale for this study is predicated on the hypothesis that the glove finger method could serve as a simple and cost-effective measure offering potential protection against SSIs. When compared to traditional methods, this technique may not only reduce surgical duration but also diminish the risk of SSIs, thereby potentially decreasing hospital stay durations. Furthermore, enhancing the understanding of factors contributing to the development of SSIs and developing effective strategies for their prevention can elevate patient care quality and alleviate the burden on healthcare systems.
The objective of this novel study is to establish proof of concept using a pilot randomized controlled trial to determine the effect of DHM compared to formula supplementation on the microbiome in full-term infants who are born via caesarean section and require supplementation. Secondarily, this study aims to compare the infant health outcomes of sleep and growth between groups to assess if these outcomes are mediated by infant feeding type or potential differences in microbial signatures. Finally, this study will compare maternal outcomes of depression, anger, breastfeeding self-efficacy and breastfeeding rates between groups. The infant gut microbiome plays a critical role in the developing immune, neurologic, and endocrine systems. Yet, most infants experience early life disruptions (ELDs) to their microbiome that have potential long-term health and development impacts. A major source of disruption is caesarean section (c-section) delivery because the infant is born surgically and is not exposed to important commensal bacteria required to establish the infant microbiome. Currently in Canada, over 28% of infants are born via c-section. Exclusive breastfeeding can improve gut microbiota composition in infants who are born via c-section. However, approximately 60% of infants born via c-section require formula supplementation in their first week of life. Evidence indicates that even one bottle of formula can further disrupt the gut microbiome. Donor human milk (DHM) is a superior alternative to formula when supplementation is required as its biotic properties minimize perturbations to the infant gut microbiome and may help to repair the microbiome in infants who experience ELDs. Yet, while DHM is well researched in preterm populations, evidence on the impact of DHM as a therapeutic intervention on the full-term infant gut microbiome is lacking. The hypothesis of this study is: that replacing formula with DHM supplementation will minimize gut microbiome dysbiosis and foster homeostasis following supplementation. In addition, it is hypothesized that improved homeostasis will promote improved sleep and growth outcomes in participant infants. Finally, mothers whose infants receive DHM will have lower depression and anger scores and higher breastfeeding self-efficacy and exclusive breastfeeding rates compared to mothers whose infants receive formula.
Maternal infectious morbidity is a common complication of cesarean delivery, especially in a poor recourse setting like ours. This study was done to compare the effectiveness of preoperative vaginal cleansing with immediate postoperative vaginal cleansing with chlorhexidine solution in preventing post-cesarean infectious morbidities. Randomized trial involving 120 consented women who had elective or emergency cesarean sections at term, 60 in each group. Group 1 had preoperative while group 2 had postoperative vaginal cleansing with 1% chlorhexidine.

The primary objective of this clinical performance study is to evaluate and further validate the clinical performance of: 1. ClariLight Influenza A/B & SARS-CoV-2 test kits and 2. ClariLight Influenza A/B & RSV test kits, for the qualitative detection and differential diagnosis of SARS-CoV-2, influenza A, influenza B, and respiratory syncytial virus (RSV) present in anterior nasal and oropharyngeal swab, in combination with an automated molecular diagnostic analyzer and sample collection tube by comparing them against a CE marked, in-vitro diagnostic device, used in the standard of care.
Inadequate treatment of infections frequently leads to complications that cause new visits to the doctor, lengthen hospital stays and can lead to sepsis, even causing the death of affected patients. Several scientific studies have documented that up to 20%-30% of antibiotic prescriptions are incorrect and do not cover the microorganism causing the infection. iAST® is a simple antibiotic prescribing aid tool that applies complex algorithms based on the latest artificial intelligence technologies to accurately predict the best specific antibiotic for a patient, before knowing the definitive microbiological results (bacterial identification and antibiogram). The objective of the present trial is to demonstrate the non-inferiority of iAST® with respect to physicians for the appropriate choice of empiric and semi-directed therapy of common infectious diseases, including sepsis, urinary tract infections and ventilator-associated pneumonias or tracheobronchitis. The adequacy of the medical prescription and the iAST® prediction will be compared taking the antibiogram report as a reference. The study design is retrospective, so that no intervention will be done on the patients. The investigators will conduct a retrospective search for infection cases and note the antibiotic treatment prescribed by the doctors. In parallel, they will enter basic patient data such as age, sex, service where they were treated, type of infection and microorganism (in the case of semi-directed treatment evaluation) into the iAST® software and will write down the first three treatment options recommended by the tool. The treatments of both arms (medical treatment and iAST® prediction) will be compared with the microbiological results and the success rate of each of them will be calculated.
Pneumocystis jirovecii is a fungus that can colonize the airways of some patients and be responsible for a disease called pneumocystosis in other patients and mainly in immunocompromised patients. Pneumocystosis was mainly linked to HIV in the 1990s, but with the advent of new immunosuppressive molecules used in cancers or autoimmune diseases and with the increase in the number of transplants, the epidemiology has changed in recent years. Studies on P. jirovecii-related mortality are only based on patients with pneumocystosis. As a result, patients who are simply colonized or patients who are sick but not treated are not taken into account in these studies. The investigators therefore wish to study the overall mortality at six weeks and at three months in all patients with a positive sample for P. jirovecii
Controlled human malaria infection (CHMI) has revolutionized the development of malaria vaccines. It involves the administration of either known numbers of sporozoites or infected erythrocytes to healthy human volunteers under a controlled environment. The use of highly sensitive molecular malaria diagnostic methods informs treatment decisions before symptom development and allows the characterization of parasite growth dynamics. Sporozoite CHMI has safely been used in six countries in Africa providing a platform to assess the efficacy of candidate malaria vaccines and study the natural immunity to malaria. Blood stage CHMI involves administration of known number of Artemether Lumefantrine sensitive infected erythrocytes in healthy volunteers, and it is a more sensitive model for modelling parasite growths and study the efficacy of blood-stage malaria vaccines. It has been safely used in Australia and Europe but not in Africa. Adaptation of this model by administration of combination of suboptimal and optimal antimalarial drugs lead to increased gametocytaemia, and infection rates in mosquitoes following standard membrane feeding assay. Such adaptation allows the model to be used to study parasite transmission from human to mosquitoes and evaluate transmission blocking malaria interventions. There is an urgent need to establish an in vivo model for early-stage clinical evaluation of transmission blocking interventions (TBI) in volunteers living in malaria endemic countries. This would allow rapid and cost-effective way to down-select transmission blocking candidate malaria vaccine and gametocidal antimalarial drugs before larger, more complex, and expensive field efficacy studies are conducted. A study done in naïve individual showed 100% success in establishing a malaria infection using 2800 P. falciparum infected RBCs, while a recent study (manuscript in development) has demonstrated success in establishing infection in Tanzanian semi-immune individuals with low malaria exposure using 1000 P. falciparum infected RBCs. We will use 1000 ALU-sensitive 3D7 P. falciparum infected RBCs to establish an in vivo transmission model for studying Transmission blocking interventions and assess the efficiency of two antimalarial drugs regimens (Piperaquine and doxycycline) to induce high levels of gametocytaemia and mosquito infection rates in healthy African adults. We will also investigate the determinants of successful transmission to mosquitoes including underlying immune responses to both asexual and sexual malaria antigens, asexual parasite dynamics and gametocyte burden, sex ratio of male and female gametocytes, and the relationship between gametocyte density and mosquito infection rate
