Continuous renal replacement therapy (CRRT) with regional citrate anticoagulation (RCA) in newborns and infants is challenging and accumulation of citrate can occur.There are only a few studies reporting the detailed data on RCA. We aimed to analyze RCA-CRRT at our institution with focus on citrate accumulation. Critically ill newborns and infants up to 11 kg of body weight (BW), treated with RCA-CRRT in the 2011-2016 period were included in this retrospective observational study.Prismaflex(R) and Multifiltrate-CiCa(R) dialysis monitors were used with either automated or manual RCA. Data was collected regarding the circuit lifetime, parameters of RCA, markers of citrate accumulation (total/ionized calcium ratio > 2.5), and metabolic complications. We included 10 children with mean age of 2.6 ± 3.8 months and BW of 4.6 ± 2.7 kg. In-hospital mortality was 60%. RCA-CRRT parameters were: blood flow 46 ± 9 mL/min (12 ± 5 mL/min/kg BW), citrate dose 2.8 ± 0.6 mmol/L of blood resulting in estimated citrate load to the patient of 1.7 ± 0.8 mmol/h/kg BW. In total, 57 dialysis circuits were used with mean filter lifetime of 39 ± 29 h. Citrate accumulation (total/ionized calcium ratio > 2.5) was observed in 7/10 patients and in 14/57 (25%) of circuits; those circuits were performed in children with lower age and BW, had higher relative blood flow and citrate load, while citrate dose was similar. When citrate load to the patient was used to predict citrate accumulation, AUC under the ROC curve was 0.78 and 1.7 mmol/h/kg BW was considered the optimal cutoff value (sensitivity 71% and specificity 72%). CRRT with RCA using equipment, developed for adult population, is feasible in newborns and infants. Signs of citrate accumulation developed relatively often. To prevent it, we suggest avoiding citrate loads above 1.7 mmol/h/kg BW, which can best be achieved by keeping the blood flow below 9 mL/min/kg BW.

Introduction and hypothesis This systematic review analyzes published studies about magnetic stimulation (MS) treatment for UUI and determines whether this treatment is effective and non-invasive. Methods A systematic literature search was conducted using PubMed, the Cochrane Library, and Embase. The international standard for reporting results of systematic reviews and meta-analyses (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) was used to guide the methodology of this systematic review. The key search terms were as follows: “magnetic stimulation” and “urinary incontinence.” We limited the time frame to articles published from 1998, when the FDA approved MS as a conservative treatment option for UI. The last search was performed on 5 August 2022. Results Two authors independently reviewed 234 article titles and abstracts, of which only 5 fitted the inclusion criteria. All 5 studies included women with UUI, but every study had different diagnostic and entry criteria for patients. They also differed in their treatment regimens and methodological approaches to assessing the efficacy of treating UUI with MS, which made it impossible to compare the results. Nonetheless, all five studies established that MS is an effective and non-invasive way of treating UUI. Conclusions The systematic literature review led to the conclusion that MS is an effective and conservative way of treating UUI. Despite this, literature in this area is lacking. Further randomized controlled trials are needed, with standardized entry criteria, UUI diagnostics, MS programs, and standardized protocols to measure the efficacy of MS in UUI treatment, with a longer follow-up period for post-treatment patients.
