Protein restriction in children with chronic renal failure

The progressive nature of renal functional impairment has been recognized for a long time (Mitch 1976, Rutherford 1977). Once glomerularfiltration rate has decreased to 25 ml!min/1.73m' progression to end stage renal disease is inevitable and independent of the primary renal disease (Leumann 1978, Arbus 1981, Warshaw 1982, Warshaw 1985, Claris-Appiani 1986, Fine 1991, Norwick 1991). Based on the assumption that renal functional deterioration is related to renal workload, Addis suggested in 1948 to decrease protein intake in patients with chronic renal failure (Addis 1917, Addis 1948). His aim was not to reduce uremic symptoms (fatigue, thirst, stunted growth, itching) but rather to prevent an increase in the "workload" of surviving nephrons of diseased kidneys in order to prevent further loss of renal function. This concept was supported by the early finding in rats that renal mass increases with long-term feeding of protein (MacKay 1928). This interesting idea lead to widespread advocation of protein restricted diets for children with chronic renal failure. Notwithstanding theoretical ideas and evidence from animal studies there are no prospective randomized controlled studies in children

In the Shadow of Asylum Decision-Making: The Knowledge Politics of Country-of-Origin Information

Country-of-origin information has secured a central place in European asylum systems, underpinning state decisions on the asylum status of refugee populations. All European states produce this type of information, and dedicated country-of-origin information units are increasingly common. This article analyzes the knowledge politics of country-of-origin information, with a focus on the relation between knowledge and decision. We are interested in this type of knowledge precisely because it is uneasily positioned in-between social scientific methodology and policy decision-making and is infused with a “pulsional normativity.” We distinguish three phases of country-of-origin information production: first, a phase of investigation, where foreign lands are reduced to stable and mobile forms so that they can be studied as research units; second, the concordance of information production, relying on standardized instruments and practical skill; and third, the consolidation phase, which involves the return of country information constructed inside research units back into the administrative and regulatory world. The final section of the article examines how complex and frail information about countries of origin becomes deployed as valid grounds for asylum decision-making

Screening, diagnosis and treatment of hypertension in obese children: an international policy comparison

Hypertension in obese children may require a different diagnostic and treatment approach from that for children with secondary hypertension, yet there is neither consensus nor a clear guideline. The aim of this study was to assess how obese children with hypertension are currently diagnosed and treated by paediatric nephrologists, what obstacles exist and what can be improved. In the period May–November 2014, an online questionnaire was sent to all members of the European Society for Paediatric Nephrology (n = 2148). Questions focused on current practices and obstacles regarding screening, diagnosis and treatment of hypertension in obese children. A total of 214 paediatric nephrologists responded. Although nearly 100 % agreed that screening of obese children for hypertension is indicated, it was current practice in only 56 % of participating countries; 88 % of respondents diagnosed hypertension with 24-h ambulatory blood pressure measurement. Diagnostics used to rule out causes or consequences of hypertension varied among the respondents; they included, in particular, the use of serum renin/aldosterone, urine sodium/potassium, and dimercaptosuccinic acid scan. Concerning treatment, 45 % of respondents preferred to start treatment with a lifestyle program, 2 % with antihypertensive medication, and 40 % with both. For 73 % of respondents, angiotensin-converting enzyme-inhibitors or angiotensin receptor blockers were the drugs of first choice. The findings of this study emphasize the urgent need for an international guideline for screening, diagnosis and treatment of hypertension in obese children

Evaluation of furosemide regimens in neonates treated with extracorporeal membrane oxygenation

INTRODUCTION: Loop diuretics are the most frequently used diuretics in patients treated with extracorporeal membrane oxygenation (ECMO). In patients after cardiopulmonary bypass (CPB) surgery, the use of continuous furosemide infusion is increasingly documented. Because ECMO and CPB are 'comparable' procedures, continuous furosemide infusion is used in newborns on ECMO. We report on the use of continuous intravenous furosemide in neonates treated with ECMO. METHODS: This was a retrospective observational study in neonates treated with continuous intravenous furosemide during ECMO. RESULTS: Thirty-one patients were included in the study. A median of 25 (9–149) hours after the start of ECMO, continuous furosemide therapy was started at a median rate of 0.08 (0.02–0.17) mg/kg per hour. The continuous furosemide dose was not changed in the individual patient. Seven patients received a furosemide bolus prior to, and five patients received additional loop diuretics during, the continuous infusion. Urine production before continuous furosemide therapy was not significantly different between patients who received a furosemide bolus prior to the infusion and those who did not receive this bolus (P = 0.2879). Although a positive effect of the 'loading' bolus was observed in urine output in the first 24 hours, there was no statistically significant difference in urine output (P = 0.0961) or in time (P = 0.1976) to reach a urine output of 6 ml/kg per hour between patients. After 24 hours, urine production remained a median of 6.2 ml/kg per hour irrespective of furosemide boluses. The forced diuresis was well tolerated as illustrated by stable haemodynamic parameters and a decrease in ECMO flow and vasopressor score over the observation period. CONCLUSION: This is the first report on continuous intravenous furosemide therapy in newborns treated with ECMO. The furosemide regimens used in this study varied widely in continuous and intermittent doses. However, all regimens achieved adequate urine output. An advantage of continuous, over intermittent, intravenous furosemide could not be documented. Furosemide dosing regimens should be developed for neonates treated with ECMO. In addition, therapeutic drug-monitoring studies are required to prevent furosemide toxicity because so far no data are available on serum furosemide levels in neonates treated with ECMO
