Observational Study
Assessing fluid balance in critically ill pediatric patients.
Monitoring fluid balance (FB) in a pediatric intensive care unit (PICU) is crucial to assess fluid overload. Pediatric intensivists (PI) frequently use the fluid intake minus output (FIMO) or FIMO with adjustments for insensible fluid loss (AFIMO). However, the accuracy of FIMO/AFIMO has never been tested in critically ill children. We designed a prospective, monocentric cohort study in a PICU of a university hospital. Body weight (BW) was measured in all children consecutively admitted to PICU and 24 h later. Every 12 h, the nurses calculated FIMO/AFIMO. Time burden and convenience of each procedure (median; [interquartile range]) were recorded and compared using a Wilcoxon test. Data were analysed using linear regression (r (2) coefficient) and the Bland-Altman plot (mean difference ± standard deviation; absolute mean difference), with a 300-ml variation of FB considered clinically relevant. Sixty consecutive patients, 304-day [39-1,565] old with admission weight of 9.2 kg [4.4-17.8] were included. Although correlations between FIMO/AFIMO and BW changes (BWC) were strong (r (2) FIMO = 0.63, p < 0.0001 and r (2) AFIMO = 0.72, p < 0.0001, respectively), agreement between FIMO/AFIMO and BWC were over 300 mL (-0.305 ± 0.451, 0.382 L and -0.007 ± 0.447, 0.302 L, respectively). No significant differences were noted between FIMO/AFIMO and BWC measurements for time burden (5 min [5-10] vs. 5 min [5-10], p = 0.84) or convenience (1 min [1-2] vs. 1 min [0-1.3], p = 0.13). ⋯ Because agreement between FIMO/AFIMO and BWC is poor during the first 24 h after admission into PICU, PIs may reserve FIMO/AFIMO to monitor FB in patients with absolute contraindications of BW measurements.

Timely recognition of deterioration of hospitalised children is important to improve mortality. We developed a modified Paediatric Early Warning Score (PEWS) and studied the effects by performing three different cohort studies using different end points. Taking unplanned Paediatric Intensive Care Unit admission as end point and only using data until 2 h prior to end point, we found a sensitivity of 0.67 and specificity of 0.88 to timely recognise patients. This proves that earlier identification is possible without a loss of sensitivity compared to other PEWS systems. When determining the corresponding clinical condition in patients with an elevated PEWS dichotomously as 'sick' or 'well', this resulted in a total of 27 % false-positive scores. This can cause motivational problems for caregivers to use the system but is a consequence of PEWS design to minimise false-negative rates because of high mortality associated with paediatric resuscitation. Using the need for emergency medical interventions as end point, sensitivity of PEWS is high and it seems, therefore, that it is also fit to alert health-care professionals that urgent interventions may be needed. ⋯ These data show the effectiveness of a modified PEWS in identifying critically ill patients in an early phase making early interventions possible and hopefully reduce mortality.

Multicenter Study
Management of adult patients with phenylketonuria: survey results from 24 countries.
Phenylketonuria (PKU) is no longer considered merely a pediatric concern; current guidelines recommend life-long treatment. However, information on the adult PKU patient population is scarce. A survey was initiated on behalf of the European PKU Group (EPG) that focused specifically on early-treated adult patients diagnosed by neonatal screening. The online survey was sent via email to 204 healthcare professionals (HCPs) in 33 countries. Eighty-one HCPs from 24 countries responded. The main findings were that the majority of adult patients with PKU in active follow-up are under 30 years of age and are managed in centers that also treat children. Seventy-eight percent of adult PKU patients in follow-up receive treatment, mainly by diet (71 %), with BH4 treatment rarely used in adulthood. Only 26 % of responding HCPs perform routine neurocognitive testing in all their adult patients. There was little consensus regarding target blood phenylalanine (Phe) concentrations, although the majority of respondents reported that their patients achieved blood Phe concentrations below 1200 μmol/l. ⋯ This survey highlights the need for blood Phe concentration target recommendations and consensus guidelines, more research into adult PKU patient management, and the need to identify those patients lost to follow-up to ensure PKU is managed for life.
