BACKGROUND: Anaemia reduces cognitive potential in school children, retards their growth and predisposes them to other diseases. As there is a paucity of data on the current burden of P. falciparum, S. mansoni and soil transmitted helminths (STH) infections and their correlation with schoolchildren's anemia in the Democratic Republic of Congo (DRC), we collect these data. METHODS: This study reports baseline data collected from a randomized controlled trial investigating the impact of IPT with SP and SP-PQ on anemia and malaria morbidity in Congolese schoolchildren (Trial registration: NCT01722539; PACTR201211000449323)...

BACKGROUND: Point-of-care testing (POCT) devices for determining pre-donation haemoglobin (Hb) concentrations mark the advent of advanced technology for blood banks. POCT devices have undergone several improvements including changes in testing methodology and size of device, befitting the needs of blood donors and blood banks in terms of safety and quality of blood components. This study was planned to evaluate the suitability of non-invasive and invasive POCT devices for blood donor Hb screening...

We conducted a study to determine whether the hemocontrol biofeedback system (HBS) can improve intradialytic hypotension (IDH) in hypotension-prone hemodialysis (HD) patients compared with conventional HD. In this multicenter prospective crossover study, 60 hypotension-prone patients were serially treated by conventional HD for 8 weeks (period A), by HD with hemoscan blood volume monitoring for 2 weeks (period B0), and by HBS HD for 8 weeks (period B1). The number of sessions complicated by symptomatic IDH during 24 HD sessions (14...

BACKGROUND: Haemodialysis with the Hemocontrol biofeedback system (HHD) is associated with improved haemodynamic stability compared with standard haemodialysis (HD) (SHD). Although the beneficial effect of HHD on haemodynamic stability is generally explained by its effect on blood volume, we questioned whether additional factors could play a role. Since HHD is associated with higher initial dialysate sodium concentrations and ultrafiltration (UF) rate, we studied whether the beneficial effect of HHD on haemodynamic stability may be explained by an increased release of the vasoconstrictor arginine vasopressin (AVP)...

RANDOMIZED CONTROLLED TRIAL

Extracellular fluid volume (ECFV) expansion in hemodialysis patients is associated with increased mortality. Attempts to remove excess fluid often result in intradialytic hypotension (IDH). Blood volume monitoring has been used to aid selection of ultrafiltration rates and dialysate conductivity to minimize IDH. Automating ultrafiltration and dialysate conductivity using the Hemocontrol Biofeedback System (HBS) has reduced IDH in IDH-prone subjects. We undertook a randomized controlled trial to determine if the HBS could safely reduce ECFV in ECF-expanded subjects...

BACKGROUND: In CKD stage 5 diabetic patients (DM), only approximately half of the interdialytic weight gain was accounted for by sodium intake. The other half was due to pure water gain, probably caused by hyperglycemia. Dialysis treatment faces two major troubles: the removal of the extra amount of water and the therapy of the compromised compensatory mechanisms. The described situation is the reason why new technologies in hemodialysis were developed. Blood volume monitoring (BVM) with regulation of ultrafiltration and sodium (Hemocontrol, Hospal, Belgium; Hameomaster, Nikkiso Co...

BACKGROUND: Volume overload contributes to the pathogenesis of hypertension in hemodialysis (HD) patients. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: The Hemocontrol (HC) system (Gambro), which automatically adjusts ultrafiltration rate and dialysate conductivity during dialysis, has been suggested to improve hemodynamic tolerance and thereby facilitate fluid removal. A 6-mo randomized, controlled trial was performed to test the hypothesis that the addition of the HC system to a systematic BP management protocol may lower home BP in comparison with standard HD as primary end point...

REVIEW

Acetate-free biofiltration (AFB) is a hemodiafiltration technique that, technically as well as biologically speaking, has all the premises for being a perfectly biocompatible technique capable of satisfying even the demands of critical patients laden with comorbidities. Important clinical benefits to patients have been reported, such as a better correction of acid-base balance, an improved nutritional status and a better hemodynamic stability. In particular, as far as the cardiovascular instability is concerned, several studies have shown that the rationale behind a better hemodynamic stability is the overall absence of acetate usually present in the dialysis bath, which often leads to an impaired vascular tone and a reduced cardiac contractility...

INTRODUCTION: Hypotension is the major cause of morbidity during hemodialysis (HD), occurring in about 20% of HD patients. Hypovolemia generated from blood volume (BV) contraction dependent on the ultrafiltration rate (UFR) and on the plasma refilling rate, is a major factor in the pathogenesis of intradialytic hypotension (IDH). Hemocontrol biofeedback system (Hemocontrol, Hospal, HBS), incorporated in the bicarbonate HD, modulates BV contraction rate by adjusting the UFR and dialysate conductivity (DC) in order to obtain predetermined BV trajectories...

Intradialytic hypotension remains a frequent complication of dialysis, occurring in up to 33% of patients. We tested a fully integrated biofeedback system (the Hemocontrol system) that monitors and regulates blood volume contraction during hemodialysis. Seven hypotension prone patients were selected for the study. We conducted a prospective crossover study alternating dialysis sessions using the blood volume regulation system and standard dialysis sessions. Event free sessions were defined as dialysis sessions not requiring any therapeutic intervention for hypotension related signs or symptoms...

BACKGROUND: Hypovolaemia has been implicated as a major causal factor of morbidity during haemodialysis (HD). In order to avoid the appearance of destabilising hypovolaemia a biofeedback control system for intra-HD blood volume (BV) change modelling has been developed (Hemocontrol, Hospal Italy). It is based on an adaptive controller incorporated into a HD machine (Integra, Hospal Italy). The Hemocontrol biofeedback system (HBS) monitors BV contraction during HD with an optical device; furthermore, HBS modulates BV contraction rates (by adjusting the ultrafiltration rate--UFR) and the refilling rate (by adjusting dialysate conductivity--DC) in order to obtain the desired pre-determined BV trajectories...
