Bedside check of medication appropriateness (BED-CMA) as a risk-based tool for bedside clinical pharmacy services: A proof-of-concept study at the trauma surgery ward.

Background: Bedside clinical pharmacy prevents drug-related problems, but is not feasible in many countries due to limited resources. Hence, clinical rules using structural information in the electronic health record can help identifying potentially inappropriate prescriptions (PIPs). We aimed to develop and implement a risk-based clinical pharmacy service and evaluate its impact on prescribing at the trauma surgery ward.

Offering Guidance and Learning to Prescribers to Initiate Parenteral Nutrition using a Validated Electronic Decision TREE (OLIVE TREE).

Parenteral nutrition (PN) is recommended in patients nutritionally at risk and unable to receive oral or enteral nutrition. A standardized electronic PN order format could enhance appropriate PN prescribing. We developed the OLIVE TREE (Offering guidance and Learning to prescribers to Initiate PN using a Validated Electronic decision TREE), embedded in our electronic health record.

End-users feedback and perceptions associated with the implementation of a clinical-rule based Check of Medication Appropriateness service.

Background: To support appropriate prescribing hospital-wide, the 'Check of Medication Appropriateness' (CMA) service was implemented at the University Hospitals Leuven. The CMA concerns a clinical rule based and pharmacist-led medication review service. The aim of this study was to explore both physicians' and pharmacists' feedback on the optimised CMA service to further improve the service.

The effectiveness of Check of Medication Appropriateness for antimicrobial stewardship: an interrupted time series analysis.

Objectives: Inappropriate prescribing of antimicrobials in hospitals contributes to the emergence of resistance and adverse drug events. To support antimicrobial stewardship (AMS), clinical decision rules focusing on antimicrobial therapy were implemented in the 'Check of Medication Appropriateness' (CMA). The CMA is a hospital-wide pharmacist-led medication review service consisting of a clinical rule-based screening for potentially inappropriate prescriptions (PIPs).

Ninety-Day Follow-up Is Inadequate for Diagnosis of Fracture-related Infections in Patients with Open Fractures.

Background: Fracture-related infection (FRI) is a challenging complication in musculoskeletal trauma surgery and often complicates the management of open fractures. The CDC currently advocates a surveillance period of 90 days after fracture fixation, but it is unclear what duration of follow-up constitutes adequate surveillance for FRI. Inadequate follow-up will underestimate infections and, in clinical research, will make any interventions studied appear better than they really are, thereby resulting in misleading conclusions.

Development and External Validation of an Online Clinical Prediction Model for Augmented Renal Clearance in Adult Mixed Critically Ill Patients: The Augmented Renal Clearance Predictor.

Objectives: Augmented renal clearance might lead to subtherapeutic plasma levels of drugs with predominant renal clearance. Early identification of augmented renal clearance remains challenging for the ICU physician. We developed and validated our augmented renal clearance predictor, a clinical prediction model for augmented renal clearance on the next day during ICU stay, and made it available via an online calculator.

Impact of duration of perioperative antibiotic prophylaxis on development of fracture-related infection in open fractures.

Introduction: Infection is a common complication of open fractures potentially leading to nonunion, functional loss, and even amputation. Perioperative antibiotic prophylaxis (PAP) is standard practice for infection prevention in the management of open fractures. However, optimal duration of PAP remains controversial.

Impact of an oral nutrition protocol in patients treated with elective radical cystectomy: a long term follow-up.

Background After radical cystectomy, delayed return of bowel function is relatively common. Although studies investigating on the best modality for delivering nutritional support to this patient group are limited, parenteral nutrition was standard of care in those patients at the urological ward of the University Hospitals Leuven. In 2015, we published the findings from our study conducted in patients undergoing elective regular radical cystectomy at the urological ward of the University Hospitals Leuven comparing the length of hospital stay in patients with early postoperative parenteral nutrition (n = 48) versus an immediate oral nutrition protocol (n = 46).

Reliability of serum creatinine-based formulae estimating renal function in non-critically ill surgery patients: Focus on augmented renal clearance.

What Is Known And Objectives: Formulae estimating glomerular filtration rate (GFR) are frequently used to guide drug dosing. The objectives of this prospective single-center study were to evaluate agreement between these equations and measured creatinine clearance (CrCl) in non-critically ill surgery patients with normal kidney function and augmented renal clearance (ARC, CrCl ≥ 130 mL/min/1.73 m²), to determine predictors for disagreement, define a GFR estimator cut-off value identifying ARC and determine the ARC prevalence and duration in non-critically ill surgical patients.

Evaluation of the FreeStyle® Libre Flash Glucose Monitoring System in Children and Adolescents with Type 1 Diabetes.

Background/aims: The FreeStyle® Libre Flash Glucose Monitoring System (FGM, Abbott) measures glucose concentrations in the interstitial fluid for up to 14 days. It has been approved for use in children aged > 4 years in January 2016. Experience in children is still limited.

A comparison between minimized extracorporeal circuits and conventional extracorporeal circuits in patients undergoing aortic valve surgery: is 'minimally invasive extracorporeal circulation' just low prime or closed loop perfusion ?

Introduction: Even though results have been encouraging, an unequivocal conclusion on the beneficial effect of minimally invasive extracorporeal circulation (MiECC) in patients undergoing aortic valve surgery cannot be derived from previous publications. Long-term outcomes are rarely reported and a significant decrease in operative mortality has not been shown. Most studies have a limited number of patients and are underpowered.

Augmented renal clearance in non-critically ill abdominal and trauma surgery patients is an underestimated phenomenon: A point prevalence study.

Background: Augmented renal clearance refers to increased renal elimination of circulating solutes as compared with normal baseline and could lead to underexposure of frequently used renally eliminated antimicrobials. The primary objective was to assess the prevalence of augmented renal clearance in an adult non-critically ill surgery population. Besides, predictors for augmented renal clearance were investigated.

Reduced length of stay in radical cystectomy patients with oral versus parenteral post-operative nutrition protocol.

Background: In Europe, parenteral nutrition is often used after radical cystectomy to avoid postoperative malnourishment. To the best of our knowledge, however, there is a paucity of data to conclude on the best modality for delivering nutritional support to this patient group.

Objective: The parenteral nutrition policy was reconsidered and an oral nutrition protocol was implemented by the clinical pharmacist and evaluated in terms of length of stay, number and type of postoperative complications and parenteral nutrition avoided costs.

Reduced cortisol metabolism during critical illness.

Background: Critical illness is often accompanied by hypercortisolemia, which has been attributed to stress-induced activation of the hypothalamic-pituitary-adrenal axis. However, low corticotropin levels have also been reported in critically ill patients, which may be due to reduced cortisol metabolism.

Methods: In a total of 158 patients in the intensive care unit and 64 matched controls, we tested five aspects of cortisol metabolism: daily levels of corticotropin and cortisol; plasma cortisol clearance, metabolism, and production during infusion of deuterium-labeled steroid hormones as tracers; plasma clearance of 100 mg of hydrocortisone; levels of urinary cortisol metabolites; and levels of messenger RNA and protein in liver and adipose tissue, to assess major cortisol-metabolizing enzymes.

Apparent elevation of cyclosporine whole blood concentrations in a renal allograft recipient.

We describe a 77-year-old cyclosporine-treated renal allograft recipient in whom falsely elevated whole blood cyclosporine concentrations were encountered using the antibody conjugated magnetic immunoassay (ACMIA) for therapeutic drug monitoring.

Absence of peroxisomes in mouse hepatocytes causes mitochondrial and ER abnormalities.

Peroxisome deficiency in men causes severe pathology in several organs, particularly in the brain and liver, but it is still unknown how metabolic abnormalities trigger these defects. In the present study, a mouse model with hepatocyte-selective elimination of peroxisomes was generated by inbreeding Pex5-loxP and albumin-Cre mice to investigate the consequences of peroxisome deletion on the functioning of hepatocytes. Besides the absence of catalase-positive peroxisomes, multiple ultrastructural alterations were noticed, including hepatocyte hypertrophy and hyperplasia, smooth endoplasmic reticulum proliferation, and accumulation of lipid droplets and lysosomes.

Neuronal migration depends on intact peroxisomal function in brain and in extraneuronal tissues.

Functional peroxisome deficiency, as encountered in Zellweger syndrome, causes a specific impairment of neuronal migration. Although the molecular mechanisms underlying the neuronal migration defect are at present unknown, the excess of very long chain fatty acids in brain, a consequence of peroxisomalbeta-oxidation deficiency, has often been hypothesized to play a major role. The purpose of the present study was to investigate the contribution of peroxisomal dysfunction in brain as opposed to peroxisomal dysfunction in extraneuronal tissues to the migration defect.
