Background: Antibiotic use can have negative unintended consequences including disruption of the human microbiota, which is thought to protect against pathogen overgrowth. We conducted a systematic review to assess whether there is an association between exposure to antibiotics and subsequent risk of community-acquired infections.

Methods: We searched MEDLINE, EMBASE and Web of Science for studies published before 30 June 2017, examining the association between antibiotic use and subsequent community-acquired infection. Infections caused by Clostridium difficile and fungal organisms were excluded. Studies focusing exclusively on resistant organism infections were also excluded.

Results: Eighteen of 22588 retrieved studies met the inclusion criteria. From these, 16 studies reported a statistically significant association between antibiotic exposure and subsequent risk of community-acquired infection. Infections associated with prior antibiotic use included Campylobacter jejuni infection (one study), recurrent furunculosis (one study), invasive Haemophilus influenzae type b infection (one study), infectious mastitis (one study), meningitis (one study), invasive pneumococcal disease (one study), Staphylococcus aureus skin infection (one study), typhoid fever (two studies), recurrent boils and abscesses (one study), upper respiratory tract infection and urinary tract infection (one study) and Salmonella infection (five studies), although in three studies on Salmonella infection the effect was of marginal statistical significance.

Conclusions: We found an association between prior antibiotic use and subsequent risk of a diverse range of community-acquired infections. Gastrointestinal and skin and soft tissue infections were most frequently found to be associated with prior antibiotic exposure. Our findings support the hypothesis that antibiotic use may predispose to future infection risk, including infections caused by both antibiotic-resistant and non-resistant organisms.

Introduction: Patients with suspected bacterial infection frequently receive empiric, broad-spectrum antibiotics prior to pathogen identification due to the time required for bacteria to grow in culture. Direct-from-blood diagnostics identifying the presence or absence of bacteria and/or resistance genes from whole blood samples within hours of collection could enable earlier antibiotic optimisation for patients suspected to have bacterial infections. However, few randomised trials have evaluated the effect of using direct-from-blood bacterial testing on antibiotic administration and clinical outcomes.

Presentation, Treatment and Outcomes of Brachial Artery Aneurysms.

J Vasc Surg

January 2025

Department of Cardiovascular Surgery, Mayo Clinic Health System, Eau Claire, WI. Electronic address:

Objective: Brachial artery aneurysms are rare entities that have typically been associated with trauma, infection, arterio-venous fistula creation or connective tissue disorders. These aneurysms are often asymptomatic, but they can also cause local tenderness or thrombo-embolic events. Due to the very low incidence of true brachial artery aneurysms, there are no standardized guidelines on their optimal management.

Low-grade infections in nonunion of the femur and tibia without clinical suspicion of infection - Incidence, microbiology, treatment, and outcome.

Injury

January 2025

Institute for Biomechanics, Paracelsus Medical University, Strubergasse 21, 5020 Salzburg, Austria; Department of Trauma Surgery, BG Unfallklinik Murnau, Professor-Küntscher-Str. 8, 82418 Murnau am Staffelsee, Germany.

Treatment algorithms for fracture nonunion depend on the presence or absence of bacterial infection. However, it is often impossible to identify infection preoperatively. While some infections may present with clinical signs of infection, low-grade infections lack infection signs and have a clinical presentation similar to aseptic nonunion.

Mannheimia haemolytica is one of the most common causative agents of bovine respiratory disease (BRD); however, antibiotic resistance in this species is increasing, making treatment more difficult. Integrative-conjugative elements (ICE), a subset of mobile genetic elements (MGE), encoding up to 100 genes have been reported in Mannheimia haemolytica genomes to confer multidrug resistance, including resistance to antibiotics commonly used in the treatment of BRD. However, the presence of antibiotic resistance genes (ARGs) does not always agree with phenotypic resistance.
