Objective: Methicillin-resistant Staphylococcus aureus (MRSA) infection appears to be increasing, the UK has one of the worst MRSA rates in Europe. As urological patients are at high risk, the aim of this study was to determine the number of newly diagnosed cases of MRSA detected in a urology ward.
Patients And Methods: The urology department serves an annual local population of greater than 500,000 with 30 inpatient beds and a tertiary population of 1 million. Over a five year period, we retrospectively recorded all patients with a new diagnosis of MRSA. We also determined colonization site and if the diagnosis of MRSA was made in an elective surgical patient or a patient admitted as an emergency.
Results: The mean number of newly diagnosed cases of MRSA was 20.6 per year. The percentage of patients with a new diagnosis of MRSA was less than or equal to 1% per year with no significant difference of new cases of MRSA over five years. Emergency patients had a trend towards a mean higher rate of MRSA. The commonest site of MRSA colonization was from catheters (32%) and open wounds (18%).
Discussion: MRSA is of concern, as compared to methicillin-sensitive staphylococcus aureus, because it is associated with high rates of clinically relevant infection, increased hospital stay and cost, greater mortality and high vancomycin usage. Mandatory reporting has shown a steady increase in the number of cases of MRSA infection over the past four years. We found that the number of newly diagnosed cases of MRSA was low, at less than or equal to 1% of patients per year. Furthermore, the number of new cases of MRSA remained constant over five years suggesting low acquisition rates in a busy UK urology ward.

Objectives: This study aimed to investigate the microbiological and clinical heterogeneity of community-onset bloodstream infections (BSIs) and identify features to support targeted empirical antibiotic therapy in the Emergency Department (ED).
Methods: Clinical and microbiological data from 992 BSI cases (1,135 isolates) diagnosed within 24 hours of ED admission at IRCCS Humanitas Research Hospital, Milan, Italy (January 2015-June 2022), were analyzed. Drug resistance was interpreted using EUCAST-2023.

Background: Postoperative infection is one of the main complications that affect the surgical effect of auricular reconstruction with tissue expansion. Understanding the susceptible time and distribution of pathogens is especially important for the treatment.
Method: The data of patients with infection after auricular reconstruction with tissue expansion from September 1, 2018 to August 30, 2024 were collected retrospectively.

: Tedizolid (TZD), an oxazolidinone, causes fewer adverse events than linezolid (LZD). However, studies on the long-term efficacy and safety of TZD, particularly in patients with hematological malignancies (HMs), remain limited. This study aimed to evaluate the safety of long-term TZD use in Japanese patients, including those with HM.

Methicillin-resistant (MRSA) can cause cases of community-acquired pneumonia, hospital-acquired pneumonia, and ventilator-associated pneumonia, and nasal colonization with this pathogen increases the risk of infection. Due to its high negative predictive value, multiple studies support using the MRSA nasal polymerase chain reaction (PCR) test to discontinue antimicrobials that target MRSA in the setting of a negative test result. The purpose of this project was to assess the utility of a protocol to allow pharmacists the ability to order MRSA nasal PCR screenings in hospitalized patients with pneumonia.
