This study reports the isolation of CA-MRSA strain which was found to colonize the nasal mucosa of a patient undergoing haemodialysis treatment. The MRSA was subjected to molecular analysis by Pulsed Field Gel Electrophoresis (PFGE), multiplex PCR assay for staphylococcal cassette chromosome mec (SCCmec) typing, and PCR detection of the pvl gene encoding for Panton-Valentine leukocidin. The analyzed MRSA harbored the SCCmec type IV and the pvl gene-two unique genetic markers of CA-MRSA. The PFGE pattern of the strain corresponded to the common European CA-MRSA (MLST Type ST80). Moreover, the strain was only resistant to beta-lactam agents and tetracycline. This study adds further evidence for the changing epidemiology of MRSA and indicates the ability of CA-MRSA to affect persons with established risk factors in addition to previously healthy individuals.

Background: Autistic people commonly have physical and mental health conditions. They also frequently experience barriers to accessing healthcare, contributing to problems identifying and treating health conditions. These factors may lead to increased and earlier morbidity and lower average life expectancy for autistic people.

ROS cause multiple forms of DNA damage, and among them, 8-oxoguanine (8-oxoGua), an oxidized product of guanine, is one of the most abundant. If left unrepaired, 8-oxoGua may pair with A instead of C, leading to a mutation of G: C to T: A during DNA replication. 8-Oxoguanine DNA glycosylase 1 (OGG1) is a tailored repair enzyme that recognizes 8-oxoGua in DNA duplex and initiates the base excision repair (BER) pathway to remove the lesion and ensure the fidelity of the genome.

Anti-Aβ immunotherapy use to treat Alzheimer's disease is on the rise. While anti-Aβ antibodies provide hope in targeting Aβ plaques in the brain there still remains a lack of understanding regarding the cellular responses to these antibodies in the brain. In this study we sought to identify acute effects of anti-Aβ antibody on immune responses.

Introduction: Previous randomised controlled trials (RCTs) have indicated a protective role of pregnancy supplementation with fish oil and high-dose vitamin D, respectively, on offspring asthma, infections and several other disorders in early childhood. However, current evidence is not considered sufficient for recommending these supplements in pregnancy. In two RCTs, we aim to investigate whether these protective effects can be confirmed in larger trials with the goal of changing clinical practice and improving child health.
