To evaluate racial disparities in weight gain velocity and body composition among preterm infants.

This observational study analyzed race differences in fat-free mass (FFM), fat mass (FM), percent body fat (%BF), and weight gain at discharge of infants born at 25-32 weeks of gestation.

No racial differences in FFM, FM and %BF measurements were found between black and white preterm infants after adjusting for birth weight, gestational age, and the presence/absence of breastfeeding (n = 143). Black infants born preterm had lower birthweights and higher weight gain from birth to discharge in unadjusted and adjusted models (13 ± 3 vs. 11 ± 3 g/kg/day; <0.001).

Black infants had higher weight gain from birth to discharge, but comparable body composition measurements at discharge. More research is needed to understand contributing factors and long-term implications of this finding.

Combined MRI/Ultrasound fusion targeted biopsy (TBx) and systematic biopsy (SBx) results in better prostate cancer (PCa) detection relative to either TBx or SBx alone, while at the cost of higher number of biopsy cores and greater detection of clinically insignificant PCa. We therefore developed and evaluated a simple decision support scheme for optimizing prostate biopsy based on multiparametric (mp) MRI assessment.

Total 229 patients with suspicion of PCa underwent mpMRI before combined TBx/SBx were retrospectively included. Impacts of MRI characteristics such as Prostate Imaging-Reporting and Data System (PI-RADS) score, lesion size, zonal origination, and location on biopsy performance were evaluated. A clinically available decision support scheme relying on mpMRI assessment was subsequently developed as a triage test to optimize prostate biopsy process. Cost (downgrade, upgrade, and biopsy core)-to-Effectiveness (detection rate) was systemically compared.

TBx achieved comparable detection rate to cdded to TBx was largely restricted to smaller PI-RADS score 3-4 lesions. Using our personalized strategy of solo TBx for PI-RADS 5 and larger (≥1 cm) PI-RADS score 3-4 lesions would avoid excess SBx in 44.5% (102/229) of all biopsy-naïve patients without compromising detection rate.BACKGROUND Non-specific pain of connective tissues and joints is one of the most frequently expressed patient concerns in everyday practice. The most common cause is osteo-degenerative changes in the cartilage and/or joint system. Metastatic calcification is a rare and initially often overlooked cause of persistent, therapy-resistant pain of connective tissues and joint apparatus in end-stage renal disease (ESRD) patients on dialysis therapy. These calcifications are induced by persistent hyperphosphatemia/hyperparathyroidism and can occur in various organs, including joints, tendons, heart valves, soft tissues, and blood vessels. CASE REPORT We report on a 46-year-old male patient with ESRD due to cANCA-associated systemic vasculitis. The patient evolved unfavorably to end-stage renal failure and started continuous ambulatory peritoneal dialysis (CAPD). Four years after initiation of CAPD, the patient reported having painful motion of the left shoulder, and symptomatic physiotherapy and non-steroidal-anti-inflammatory-drugs (NSAIDs) were prescribed. An X-ray examination of the left shoulder showed severe periarticular calcifications. Repeated nutritional counselling was offered, and intensive phosphate-binder therapy was administered, resulting in a reduction in phosphate levels from 2.10 mmol at the time of diagnosis to 1.26 mmol/l 16 months later. Radiological reevaluation showed a near complete resolution of the periarticular calcifications. CONCLUSIONS Metastatic calcifications may arise in ESRD patients despite only moderately elevated blood phosphate levels. Intensive measures to reduce the phosphate load to normal levels should be implemented and can lead to almost complete resolution of ectopic calcifications in affected patients.BACKGROUND Acute pancreatitis (AP) is a common acute abdominal disease. Rapid evaluation of the severity is important for AP prognosis and treatment. Free triiodothyronine (fT3) level is associated with the prognosis of AP patients. This study aimed to investigate the fT3 level in patients with acute pancreatitis; early warning signs of inflammation, including interleukin-6 (IL-6) and interleukin-10 (IL-10); and the correlation of fT3 level with illness severity. MATERIAL AND METHODS Enrolled AP patients (N=312) were divided into an SAP group (N=92) and a non-SAP group (N=220) according to the Revision of Atlanta classification. Blood or tissue samples and baseline clinical characteristics were recorded. The t test and chi-square test were used to evaluate differences between the 2 groups. Multivariate logistic regression analysis and receiver operating characteristic (ROC) curves were used to investigate protective factors. One-way repeated measures analysis of variance was used to evaluate the prognosis of SAP patients. RESULTS In our study, compared with APACHII score (AUC 0.829 [95% CIs 0.769-0.889]) and Ranson score (AUC 0.629 [95% CIs 0.542-0.715]), our predictive model (AUC 0.918 [95% CIs 0.875-0.961]) showed better prognostic performance in predicting poor patient outcomes. In the SAP group, changes in fT3 level were significantly associated with prognosis (P less then 0.05). CONCLUSIONS The predictive model can improve the diagnostic accuracy and prediction of the severity of disease. FT3 level could be used as an independent risk factor to predict the mortality of SAP patients.BACKGROUND Cefepime, a fourth-generation cephalosporin, has a known adverse effect of neurotoxicity. It occurs notably in patients with end-stage renal disease, but symptom resolution typically occurs within a median of 2 days following drug discontinuation. CASE REPORT We present a patient with end-stage renal disease on hemodialysis (TWThSat) who developed prolonged neurotoxicity lasting longer than 1 week complicated by nonconvulsive status epilepticus 2 days after cefepime discontinuation. She presented initially with a right upper-extremity arteriovenous graft infection from extended-spectrum beta-lactamase Escherichia coli, and was treated with cefepime. She eventually developed acute encephalopathy, and cefepime was discontinued. However, 2 days later, she developed seizures with worsened mental status. She was stabilized on levetiracetam and lorazepam, but developed hypotension in the Neurological Intensive Care Unit (Neuro-ICU), delaying hemodialysis. click here Hemodialysis was performed 6 days after cefepime discontinuation once she was stabilized, and her mental status improved 1 to 2 days after, with full improvement 20 days after admission. She was discharged on levetiracetam and meropenem. In addition, we review risk factors and symptomology of cefepime-induced neurotoxicity and discuss important management issues. CONCLUSIONS Careful attention should be paid when administering cefepime to patients with end-stage renal disease. Patients showing signs of encephalopathy should not be on cefepime any longer, and more aggressive measures may be taken, such as prompt hemodialysis, assessment of cefepime blood levels, and electroencephalogram (EEG) to monitor for signs of seizures. Prolonging hemodialysis in patients with signs of cefepime neurotoxicity can pose a danger for more serious sequelae, such as status epilepticus. Close monitoring of patients at high risk of developing adverse events from cefepime administration can ensure patient safety and well-being.
The authors describe a patient with substance use disorder admitted to the hospital with septic shock and multiorgan failure, in whom the serum concentration of methadone kept increasing despite discontinuation of the drug. Therapeutic drug monitoring was performed to monitor the methadone serum concentration during treatment of the underlying diseases.

Although the relationship between NUDT15 and thiopurine-induced leukopenia has been proven in previous studies, no prominent factors explaining interindividual variations in its active metabolite, 6-thioguanine nucleotide (6-TGN), and clinical efficacy have been identified. In this study, the correlation between genotypes (thiopurine S-methyltransferase, NUDT15, and ITPA polymorphisms), 6-TGN concentrations, and clinical outcomes (efficacy and side effects) in patients with inflammatory bowel disease were investigated.

In total, 160 patients with inflammatory bowel disease were included, and the 3 genotyped genes and 6-TGN levels were measured by high-performance liquid chromatography. Statistical analyses and calculations were performed to determine their relationships.

ITPA genotypes and 6-TGN concentration were both associated with the clinical effectiveness of azathioprine (P = 0.036 and P = 4.6 × 10-7), with a significant correlation also detected between them (P = 0.042). Patients with ITPA variant alleles exhibited higher 6-TGN levels than those with the wild-type allele. In addition, the relationship between NUDT15 and leukopenia and neutropenia was confirmed (P = 1.79 × 10-7 and 0.002).

In summary, it is recommended that both ITPA and NUDT15 genotyping should be performed before azathioprine initiation. Moreover, the 6-TGN concentration should be routinely monitored during the later period of treatment.

Therapeutic drug monitoring (TDM) aims to individualize drug therapy. This systematic review provides a state-of-the-art overview of the benefits of adding the dose-related reference range (DRR) as a second reference range to the set of tools used by TDM for measurement and evaluation. It discusses alternative pharmacokinetic approaches for individualization of drug therapy.

Literature was searched in PubMed. Textbooks provided Bateman transformations for calculating expected drug concentrations at various times after drug application in "normal patients," that is, the population of phase II clinical trials. The review compiles conditions and prerequisites for these transformations to be valid.

Relating a measured drug concentration to the orienting therapeutic reference range provides pharmacodynamic information for improving the benefit-to-risk ratio of desired drug effects versus adverse drug effects. The discriminating DRR considers a patient's individual pharmacokinetic situation. DRR is statisticamedication to the patient's individual needs (individualization of drug therapy).
