Introduction: Critically-ill patients are commonly fed with EN via open system (OS) or closed system (CS). Several studies showed that patients on CS had received greater volume of EN compared to OS.
Objective: As there was no study conducted in Malaysia, hence this study is conducted to compare the energy and protein adequacy of both systems.
Methodology: This cohort prospective study was conducted in GICU (OS) and NICU/NHDW (CS) in Hospital Kuala Lumpur. Patients aged ≥18 years and fed by feeding pump in OS were included. Patients who were moribund or not given EN were excluded. Patients’ demographic data and disease severity score were collected on day 1 in ICU and followed for 5 days until decease or discharge. Adequacy was determined by percentage of energy/protein received from requirements.
Results: Fifty-five patients were included (25 OS and 30 CS) with mean aged 45.41±17.46 years old, 78.2% male and 65.5% Malay. The mean SAPS II, SOFA score and ICU LOS were 46.47±10.65, 8.60±3.64 and 9.24±7.91 days respectively. The ICU mortality was 20%. EN was started about 2.56±2.89 days after ICU admission and the mean adequacy of energy was 74.56±32.23%, while protein adequacy was and 69.15±35.78%. Compared with the CS, OS were significantly older than CS (51 years old vs 42.5 years old; p=0.035) and had a higher SOFA score (10 vs 7.5; p= 0.014). No difference in ICU LOS and mortality between group were found. Energy (45.64% vs 96.71%; p<0.001) and protein adequacy (38.78% vs 94.12%; p<0.001) were significantly higher in the CS than the OS.
Conclusion: CS as compared with OS may improve nutritional adequacy as CS delivered more 108% energy and 141% protein than OS. The difference in adequacy might be attributed to these factors; feeding method used in the system, patients’ characteristics and condition rather than the feeding system itself.

INTRODUCTION: Haemoglobin Constant Spring (Hb CoSp) and Haemoglobin Adana (Hb Adana), are two non-deletion type of α-thalassemia reported in Malaysia. Owing to their structural instability, they cause hemolysis and hyperbilirubinemia. This observational study was part of a large study investigating multiple factors associated with severe neonatal jaundice. In this part we aimed to determine the prevalence of Hb CoSp and Hb Adana and their association with clinically significant neonatal hyperbilirubinemia (SigNH, total serum bilirubin (TSB>290µmol/L)) among jaundiced Malaysian term neonates.
MATERIALS AND METHODS: The inclusion criteria were normal term-gestation neonates admitted consecutively for phototherapy. PCR-restriction fragment length polymorphism method was applied on DNA extracted from dry blood spot specimens of each neonate to detect for Hb CoSp and Hb Adana gene. Positive samples were verified by gene sequencing.
RESULTS: Of the 1121 neonates recruited (719 SigNH and 402 no-SigNH), heterozygous Hb CoSp gene was detected in only two (0.27%) neonates. Both were SigNH neonates (0.3% or 2/719). No neonate had Hb Adana variant.
CONCLUSION: Hb CoSp was not common but could be a risk factor associated with SigNH. No Hb Adana was detected.
