The Effect of Adjunctive Melatonin With Colistin in Patients With Multidrug-Resistant Gram-Negative Bacterial Infections

This study evaluates whether adding melatonin to standard colistin therapy improves outcomes in patients with multidrug-resistant (MDR) Gram-negative bacterial infections. These infections are difficult to treat and are associated with high morbidity and mortality, particularly in critically ill patients. Colistin is often used as a last-line antibiotic for these infections; however, its effectiveness may be limited, and it is associated with side effects such as kidney injury. Melatonin, a naturally occurring hormone, has antioxidant, anti-inflammatory, and immune-modulating properties that may enhance the effectiveness of antibiotics and reduce treatment-related complications. In this randomized, double-blind, placebo-controlled study, adult patients receiving colistin will be assigned to receive either melatonin or a placebo in addition to standard care. The study will assess whether melatonin improves oxidative stress, infection control, and clinical outcomes while maintaining safety.

Ocular Rosacea Biome Study

Ocular rosacea is an inflammatory disease of the eyelids and ocular surface. Like the facial disease, the ocular condition is chronic and recurrent. Sequelae of ocular rosacea vary from mild to severe. Ocular rosacea may cause chronic eye redness, blepharitis, recurrent chalazia, dry eye, corneal erosion, corneal vascularization, and corneal ulceration. Rosacea affecting the cornea can result in vision loss. Prescription eye drops and ointments can be used topically to control mild ocular rosacea. However, severe disease, or rosacea that is not well controlled with local treatments is treated systemically. The most commonly used systemic treatment for rosacea is the bacteriostatic antibiotic doxycycline. Rosacea treatment doses of doxycycline vary widely. Treatment-dose doxycycline for systemic infections is 100mg twice a day. However, as rosacea is considered an inflammatory disease, doxycycline is often dosed at what is termed, sub-microbial dose doxycycline (SDD). Initially introduced in the oral medicine literature, SDD are doses 40mg and lower because systemic administration at this dose does not appear to alter the oral mucosa flora or increase resistance rates when given long-term for periodontal disease. Whereas 100mg doxycycline, even when given short term, may increase the percentage of culturable nasopharyngeal flora that is resistant to doxycycline. The FDA does not categorize SDD an antibiotic, stating this dosing is expected to exhibit only anti-inflammatory activity.

Optimizing Antibiotics Prescription

Interventions that are low-cost, do not add substantially to the physician workload, are consistent with good physician practices and WHO guidelines, and serve as a reminder on the risks of overprescribing antibiotics are critically needed. The overall goal of the proposed project is to test the effect of two behavioral interventions targeted to junior physicians-specifically, requiring them to specify the diagnosis in the prescription note and providing feedback-on their antibiotics prescription rate; examine the intervention's effects across gender and caste; and draw lessons for scaling up the intervention.

Multicentre Study Analysing Wastewater to Monitor Bacterial Resistance to Antibiotics in Residential Care Homes for Elderly Dependents

This study aims to model the relationship between the prevalence of ESBL-E and CPE carriage among nursing home residents and their respective concentrations in wastewater discharged from the facility.

Surveillance of Healthcare-associated Infections & Antimicrobial Resistance

The aims of this project, called "Surveillance of Healthcare-associated infections \& Antimicrobial Resistance", or "SHARE", are to 1) enhance laboratory capacity to detect emerging AMR patterns; 2) strengthen hospital epidemiology programs to use data to prevent, detect, and contain emerging AMR threats; 3) deploy study teams to answer critical public health surveillance questions, and 4) to build a national network of infection prevention and control (IPC) resources to prevent, detect, and contain emerging infectious disease threats

Azithromycin for Child Survival in Niger II

Several randomized controlled trials have demonstrated that azithromycin mass drug administration (MDA) reduces child mortality, but increases antimicrobial resistance (AMR). The World Health Organization (WHO) guidelines for this intervention specify that implementation must be accompanied by continued monitoring of mortality and AMR. Niger is expanding the azithromycin MDA program nationwide. To establish monitoring of mortality and AMR as part of this program as well as to leverage the infrastructure to evaluate other child health interventions, AVENIR II is designed as an adaptive platform trial with monitoring and re-randomization every 2 years.

Monitoring of Antimicrobial Resistance Based on Metagenomics Analyses in Pneumonia Patients

Monitoring of antimicrobial resistance (AMR) based on metagenomics analyses in pneumonia patients is critical for optimizing clinical diagnosis and treatment and improving clinical prognosis. This study is designed to ask the following key questions: 1. What is the microbiome maps of patients with severe pneumonia and mild pneumonia ? 2. How many pathogen resistance genes are carrying in severe pneumonia and mild pneumonia ? 3. What is the genetic diversity of key pathogens detected in severe pneumonia and mild pneumonia during 2019-2025?
