BACKGROUND: Previous studies have identified patients infected with Mycobacterium chimaera (M. chimaera) subsequent to cardiac surgery. Water tanks in heater-cooler units (HCUs) used cardiac heart surgery was traced as source. The aim was to investigate occurrence of M. chimaera and other microorganisms in HCUs and evaluate the silver-ion cleaning routine. METHOD: Five HCUs were disinfected with silver-ions and examined for mycobacteria directly (15 min) after the disinfection procedures and later on three occasions (3, 6, 10 weeks)...

Outpatient parenteral antimicrobial therapy (OPAT) programmes facilitate hospital discharge, but patients remain at risk of complications and consequent healthcare utilisation (HCU). Here we elucidated the incidence of and risk factors associated with HCU in OPAT patients. This was a retrospective, single-centre, case-control study of adult patients discharged on OPAT. Cases (n = 63) and controls (n = 126) were patients that did or did not utilise the healthcare system within 60 days. Characteristics associated with HCU in bivariate analysis (P ≤ 0...

AIMS: PEGylated human truncated cystathionine beta-synthase, lacking the C-terminal regulatory domain (PEG-CBS), is a promising preclinical candidate for enzyme replacement therapy in homocystinuria (HCU). It was designed to function as a metabolic sink to decrease the severely elevated plasma and tissue homocysteine concentrations. Here we evaluated pharmacokinetics (PK), pharmacodynamics (PD) and sub-chronic toxicity of PEG-CBS in homocystinuric mice and wild type rats and monkeys to estimate the minimum human efficacious dose for clinical trials...

RATIONALE, AIMS, AND OBJECTIVES: Patients with somatoform disorders are frequent attenders in primary and secondary care. While co-morbid mental disorders, especially depression and anxiety, are frequently present, there is controversy on whether mental co-morbidity leads to higher health care utilization (HCU). The present paper investigates the influence of co-morbid depressive and anxiety disorders on primary, specialized somatic and mental HCU in primary care patients with somatoform disorders...

Children frequently refrain from disclosing being bullied. Early identification of bullying by healthcare professionals in children may prevent adverse health consequences. The aim of our study was to determine whether Health Care Utilisation (HCU) is higher in 9-year-olds who report being bullied and factors influencing type of HCU. The study consists of cross-sectional surveys of Child Cohort of Irish National Longitudinal Study of Children (Wave 1), 8,568 9-year-olds, and their carers. Being bullied was assessed by a self-reported questionnaire completed by children at home...

THEORETICAL BACKGROUND: In older people, anxiety disorders are among the most prevalent mental disorders and a high proportion suffers from clinically relevant anxiety symptoms. Despite studies suggesting an association of anxiety with health care utilization (HCU) and a resulting economic burden to the health care system, we found no review systematically analyzing evidence on this association in older people. OBJECTIVE: To analyze and synthesize evidence on the association of anxiety disorders and symptoms with HCU and costs in people aged 65 years and over in a systematic review...

Canadian hospitals were made aware of the risk of Mycobacterium chimaera infection associated with heater-cooler units (HCUs) through alerts issued by the US food and Drug Administration (FDA) and the US Centers for Disease Control and Prevention (CDC). In response, most hospitals conducted retrospective reviews for infections, informed exposed patients, and initiated a requirement for informed consent with HCU use.

OBJECTIVES: Toll-like receptor (TLR) -9 could have importance in human S. aureus immunity, but population level evidence for this hypothesis is missing. METHODS: We phenotyped 603 volunteers for S. aureus nasal carriage using four consecutive swabs, genotyped TLR9 promotor variants in 106 persistent carriers and 219 non-carriers, measured TLR9-mRNA expression in whole blood after stimulation with viable S. aureus, and studied mutual associations of carriage, transcriptional activity, and single nucleotide polymorphisms while accounting for sex and hormonal contraceptive use (HCU+/- )...

Classical homocystinuria (HCU) is the most common inherited disorder of sulfur amino acid metabolism caused by deficiency in cystathionine beta-synthase (CBS) activity and characterized by severe elevation of homocysteine in blood and tissues. Treatment with dietary methionine restriction is not optimal, and poor compliance leads to serious complications. We developed an enzyme replacement therapy (ERT) and studied its efficacy in a severe form of HCU in mouse (the I278T model). Treatment was initiated before or after the onset of clinical symptoms in an effort to prevent or reverse the phenotype...

Recently, surgical site infections due to non-tuberculous mycobacteria (NTM) have been linked to heater-cooler unit contamination. The European Centre for Disease Prevention and Control and manufacturers now recommend the use of hydrogen peroxide in filtered water to fill heater-cooler unit tanks. After implementation of these measures in our hospital, heater-cooler units became heavily contaminated by opportunistic waterborne pathogens such as Pseudomonas aeruginosa and Stenotrophomonas maltophilia. No NTM were detected but fast-growing resistant bacteria could impair their detection...

Parenting children with conduct problems (CP) is challenging, yet very little is known about the impact of the child's behaviour on family functioning or how parents of children with CP perceive their child. The aim of this research was to examine whether families with children with CP and high vs. low levels of callous-unemotional traits (HCU vs. LCU) experience differences in family functioning and parental perceptions. One hundred and one parents/caregivers of boys aged 11-16 [Typically developing (TD) n = 31; CP/HCU n = 35; CP/LCU n = 35] completed the McMaster Family Assessment Device, measuring multiple domains of family functioning...

Classical homocystinuria (HCU) is the most common loss-of-function inborn error of sulfur amino acid metabolism. HCU is caused by a deficiency in enzymatic degradation of homocysteine, a toxic intermediate of methionine transformation to cysteine, chiefly due to missense mutations in the cystathionine beta-synthase (CBS) gene. As with many other inherited disorders, the pathogenic mutations do not target key catalytic residues, but rather introduce structural perturbations leading to an enhanced tendency of the mutant CBS to misfold and either to form nonfunctional aggregates or to undergo proteasome-dependent degradation...

INTRODUCTION: Mycobacterium chimaera ( M. chimaera) is a recently characterised bacterium that can cause life-threatening infections in small numbers of patients who undergo cardiopulmonary bypass during cardiac surgery. The likely mode of transmission is thought to occur through aerosolisation from contaminated water reservoirs. The airborne bacteria then contaminate the surgical field, leading to an infection months or even years later. The preferred practical solution to disrupt the transmission of these airborne bacteria to the patient is to remove the heater-cooler units (HCUs) from the operating room (OR)...

Cystathionine β-synthase-deficient homocystinuria (HCU) is a poorly understood, life-threatening inborn error of sulfur metabolism. Analysis of hepatic glutathione (GSH) metabolism in a mouse model of HCU demonstrated significant depletion of cysteine, GSH, and GSH disulfide independent of the block in trans-sulfuration compared with wild-type controls. HCU induced the expression of the catalytic and regulatory subunits of γ-glutamyl ligase, GSH synthase (GS), γ-glutamyl transpeptidase 1, 5-oxoprolinase (OPLAH), and the GSH-dependent methylglyoxal detoxification enzyme, glyoxalase-1...
