Background: Critical illness refers to a wide spectrum of life-threatening medical or surgical conditions usually requiring an intensive care unit level of care. In most of these patients a common pathophysiological process is often present, namely infection, trauma, or major surgery. These factors initiate an inflammatory cascade leading to activation of regulatory mechanisms in order to control the intensity of the inflammatory response. The prognosis of critically ill patients usually depends on illness severity, intensity of the biological inflammatory response and nutritional status. Objective and Methodology: This analytical cross-sectional study of 82 mechanically ventilated critically-ill patients with hypoalbiminemia admitted in the ICU and NCCU of St. Luke’s Medical Center from January 1 to December 31, 2008, aimed at determining the odds ratio between hypoalbuminemia and those with albumin >3mg/dl in terms of failure in weaning. Also it seeks to determine the prevalence of hypoalbuminemia among mechanically ventilated patients in the ICU; characterize the patients involved in the study in terms of age, sex, APACHE II score, and co-morbidities/ underlying illness; and to determine the manner of serum albumin correction. A 2x2 table analysis was computed to measure the odds ratio. Chi-Square for qualitative dichotomous variables and unpaired t-test for continuous variables are the statistical tools employed to interpret the present data. Results: Eighty-two of the 109 of patients had hypoalbuminemia, giving a prevalence of 0.75. Of the 82 hypoalbuminemic patients, 26 subjects failed to be weaned off mechanical ventilator support compared to two subjects of 27 patients with no hypoalbuminemia. An odds ratio of 5.8 was obtained. Patient’s demographics of both groups did not significantly differ except for hypertension. The biochemical parameters prior to weaning (hemoglobin, sodium, potassium, calcium and magnesium) were not significantly different between hypoalbuminemic and non hypoalbuminemic patients. From our results, 22.6% of the patients were started on albumin IV infusion at a level of <2.4g/dL. The rest did their correction through diet. Conclusion: Hypoalbuminemia with a serum albumin level of <3mg/dl is associated with negative outcome of weaning from mechanical ventilation. The odds that a patient will have failure in weaning was 6 times more likely in subjects with serum albumin <3 mg/dl.

INTRODUCTION: The risk for diabetes progression varies greatly in individuals with type 2 diabetes mellitus (T2DM). We aimed to study the clinical determinants of diabetes progression in multiethnic Asians with T2DM. MATERIALS AND METHODS: A total of 2057 outpatients with T2DM from a secondary-level Singapore hospital were recruited for the study. Diabetes progression was defined as transition from non-insulin use to requiring sustained insulin treatment or glycated haemoglobin (HbA1c) ≥8.5% when treated with 2 or more oral hypoglycaemic medications. Multivariable logistic regression (LR) was used to study the clinical and biochemical variables that were independently associated with diabetes progression. Forward LR was then used to select variables for a parsimonious model. RESULTS: A total of 940 participants with no insulin use or indication for insulin treatment were analysed. In 3.2 ± 0.4 (mean ± SD) years' follow-up, 163 (17%) participants experienced diabetes progression. Multivariable LR revealed that age at T2DM diagnosis (odds ratio [95% confidence interval], 0.96 [0.94-0.98]), Malay ethnicity (1.94 [1.19-3.19]), baseline HbA1c (2.22 [1.80-2.72]), body mass index (0.96 [0.92-1.00]) and number of oral glucose-lowering medications (1.87 [1.39-2.51]) were independently associated with diabetes progression. Area under receiver operating characteristic curve of the parsimonious model selected by forward LR (age at T2DM diagnosis, Malay ethnicity, HbA1c and number of glucose-lowering medication) was 0.76 (95% CI, 0.72-0.80). CONCLUSION Young age at T2DM diagnosis, high baseline HbA1c and Malay ethnicity are independent determinants of diabetes progression in Asians with T2DM. Further mechanistic studies are needed to elucidate the pathophysiology underpinning progressive loss of glycaemic control in patients with T2DM.

OBJECTIVETo assess the biological effects of the six-herb mixture Anti-Insomia Formula (AIF) extract using caffeine-induced insomnia Drosophila model and short-sleep mutants.

METHODSCaffeineinduced insomnia wild-type Drosophila and short-sleep mutant flies minisleep (mns) and Hyperkinetic(Y) (Hk(Y)) were used to assess the hypnotic effects of the AIF in vivo. The night time activity, the amount of night time sleep and the number of sleep bouts were determined using Drosophila activity monitoring system. Sleep was defined as any period of uninterrupted behavioral immobility (0 count per minute) lasting > 5 min. Night time sleep was calculated by summing up the sleep time in the dark period. Number of sleep bouts was calculated by counting the number of sleep episodes in the dark period.

RESULTSAIF at the dosage of 50 mg/mL, effectively attenuated caffeine-induced wakefulness (P<0.01) in wild-type Canton-S flies as indicated by the reduction of the sleep bouts, night time activities and increase of the amount of night time sleep. AIF also significantly reduced sleeping time of short-sleep Hk(Y) mutant flies (P<0.01). However, AIF did not produce similar effect in mns mutants.

CONCLUSIONAIF might be able to rescue the abnormal condition caused by mutated modulatory subunit of the tetrameric potassium channel, but not rescuing the abnormal nerve firing caused by Shaker gene mutation. This study provides the scientific evidence to support the use of AIF in Chinese medicine for promoting sleep quality in insomnia.
