In North America, up to 5% of preschoolers develop community-acquired pneumonia (CAP) every year. Pneumonia is the second-leading reason for paediatric hospitalization in both Canada and the US; approximately 20% of children hospitalized with CAP may need intensive care, which can result in significant morbidity. Given this burden of disease, it is critical that CAP is managed appropriately. Specific therapy for CAP is dependent on microbiologic aetiology, as bacterial disease will improve with antibiotic treatment.

The goal of this clinical trial is to determine if a "watch and wait" antibiotic strategy, called Safety Net Antibiotic Prescribing (SNAP), can safely reduce unnecessary antibiotic use while ensuring that children diagnosed with community-acquired pneumonia get better from their illness. The main aims of this study are: * To compare the effectiveness of SNAP versus immediate antibiotic prescribing in children with mild community-acquired pneumonia (CAP) * To identify which patient groups benefit most from the SNAP strategy * To identify factors that shape implementation of each prescribing strategy. Researchers will compare the SNAP strategy (where parents or guardians are instructed to give antibiotics only if their child is not improving after 72 hours, or sooner if they are worsening) to the immediate antibiotic prescribing strategy (where parents or guardians are instructed to give the antibiotics right after their healthcare visit) to see if one strategy is more effective than the other. Participants will be randomly assigned to either the immediate antibiotic group or the SNAP group at enrollment. Participation lasts 14 days with follow-up surveys at 4, 7, and 14 days after enrollment.

The goal of this clinical trial is to learn if icosapent ethyl (Vascepa) works to lessen the amount of inflammation in adults diagnosed with Community-Acquired Pneumonia (CAP). The main question it aims to answer is: What is the effect of taking Vascepa on inflammation in the arteries in patients with CAP? Researchers will compare the drug Vascepa to a placebo (a look-alike submstance that contains no drug) to see if Vascepa works to reduce inflammation in patients with CAP. Participants wil: * take Vacscepa or a placebo twice a day for 6 months * Visit the clinic 3 times (baseline, 30 days, and 6 months) for checkups and tests

OPT101-100-40 is a multicenter, randomized, placebo-controlled, multiple-ascending-dose, sequential-group, investigator- and participant-blinded, sponsor-unblinded, study of OPT101 vs placebo when administered for up to 4 days to patients admitted to the hospital for treatment of Community Acquired Pneumonia (CAP) with sepsis. This study will be performed in patients with Community Acquired Pneumonia (CAP) with Sepsis, who are 18 years or older to evaluate the safety and tolerability of OPT101 in a population with elevated levels of pathologic CD40.

The purpose of this study is to reduce the exposure of broad-spectrum antimicrobials by optimizing the rapid detection of CAP pathogens and improving rates of de-escalation following negative cultures. To accomplish this, we will perform a 3-year, pragmatic, multicenter 2 X 2 factorial cluster randomized controlled trial with four arms: a) rapid diagnostic testing b) pharmacist-led de-escalation c) rapid diagnostic testing + pharmacist-led de-escalation and d) usual care

Background: Each year, the number of cases of tick-borne diseases increases. The deer tick (Ixodes scapularis) is the vector of at least 7 pathogens that cause human diseases, including Lyme disease. Researchers want to learn more to help them develop vaccines against ticks in the future. Objective: To learn how people s bodies, particularly the skin, respond to tick bites. Eligibility: Healthy adults aged 18 years and older who have no known history of a tick-borne disease or tick bite exposure. Design: Participants will be screened with a medical history, physical exam, and blood tests. Participants will have 2 skin punch biopsies of healthy skin. For this, a sharp instrument will be used to remove a round plug of skin about the size of a pencil eraser. Participants will then have 10 clean laboratory-bred ticks placed at 2 different sites on their skin (20 ticks total). The ticks will be removed from the first site 1 day after placement and from the second site 2-4 days after placement. Participants will complete symptom diary cards. They will answer questions about itching at the tick feeding sites. They will give blood samples. Photos will be taken of the tick feeding sites. Skin punch biopsies will be collected at the sites of the tick bites. Participants will repeat the tick feeding procedures 2 times, each 2-8 weeks apart. For the 2nd and 3rd procedures, 10 clean laboratory-bred ticks will be placed at 1 site. The ticks will be removed 2-3 days after tick placement. They will have telephone follow-up visits after each procedure. After the final tick removal, participants will have follow-up visits in 4-6 weeks and again in 3 months. They will give blood samples and discuss how they are feeling. Participation will last about 5-7 months.
