Background: Vicks VapoRub (VVR) is a globally popular over-the-counter remedy marketed for use as a topical antitussive and analgesic. This review seeks to provide health professionals and care providers with a thorough summary of the benefits and complications associated with VVR use reported in the medical literature, identify off-label consumer behaviors that might increase the risk of health complications, and encourage further research into over-the-counter (OTC) medications.
Methods: Three databases-PubMed, Web of Science, and Embase-aided in creating a pool of 220 studies. For inclusion, studies had to discuss the therapeutic application of VVR in humans or a complication arising from its use.
Findings: Thirty-seven articles were found to meet inclusion criteria. Nine synthesis groups were created: three groups concern the product's efficacy in regard to upper respiratory tract infection (URTI) symptom treatment ( = 7), onychomycosis treatment ( = 2), and in the context of wound care ( = 2). Six groups collate case reports that describe VVR-related complications, including VVR-associated lipid pneumonia ( = 11), ocular injury ( = 5), camphor toxicity ( = 5), dermatological conditions ( = 3), psychosis ( = 1), and respiratory distress ( = 1). The evidence around the use of VVR for the treatment of URTI symptoms and onychomycosis is limited and inconclusive. Even more limited cross-sectional data concerns its use in wound care. Many of the complications described in our study (, multi-organ failure, ocular evisceration, severe pneumonia) involve product misuse. This review was designed to help guide patients on the safe and appropriate use of VVR (, advising patients to avoid heating, ingesting, or intranasal/intrabuccal/ocular application of the product). In general, the severity of complications associated with misuse of VVR highlights the importance of complementary and alternative medicine disclosure and discussion.

Ventilator-associated pneumonia (VAP) is a frequent complication in injured patients. Multiplex polymerase chain reaction (PCR) facilitates rapid identification of many respiratory pathogens prior to formal culture results. Our objective was to evaluate the effect of multiplex PCR implementation in a trauma intensive care unit (TICU) on antibiotic utilization and de-escalation.

Aims: To examine the risk of perinatal mental illness, including new diagnoses and recurrent use of mental healthcare, comparing women with and without traumatic brain injury (TBI), and to identify injury-related factors associated with these outcomes among women with TBI.
Methods: We conducted a population-based cohort study in Ontario, Canada, of all obstetrical deliveries to women in 2012-2021, excluding those with mental healthcare use in the year before conception. The cohort was stratified into women with no remote mental illness history (to identify new mental illness diagnoses between conception and 365 days postpartum) and those with a remote mental illness history (to identify recurrent illnesses).

Background: Clozapine-induced gastrointestinal hypomotility and constipation can result in severe and sometimes fatal gastrointestinal complications. Laxatives should be prophylactically prescribed with clozapine, but this is inconsistently achieved. Digital clinical decision support (CDS) alerts can promote safer prescribing.

Hemophilia is a rare X-linked bleeding disorder caused by mutations in the F8 or F9 gene (hemophilia A or B), leading to deficient factor VIII or IX proteins, respectively. Hemophilia-related complications caused by bleeding into the joints (the hallmark of hemophilia) and age-related comorbidities occur frequently and impact the functionality and quality of life of persons with hemophilia (PwH). Given the chronic nature of hemophilia, we hypothesized that hemophilia has an association with accelerated biological aging.

Recent research has revealed a close association between obesity and various metabolic disorders, including renal metabolic diseases, but the mechanism is still unknown. This study explored the role of p16INK4a in obesity-related kidney fibrosis and evaluated its potential as a therapeutic target. Using wild-type (WT) mice and p16 KO mice, we fed both groups a high-fat diet (HFD) for 6 months.
