Background: A number of Traditional Chinese
Medicine (TCM) preparations are being used for the
treatment of diabetes mellitus. Some components
of these preparations have biochemical effects other
than those of lowering blood glucose and indeed have
been used for other medical indications in traditional
practice. The primary objective of the study was to
determine the effect of the oral mixture of Traditional
Chinese Medicine for diabetes (TCM-D™ complex) on
blood glucose level and the biochemical changes if any,
on the liver (ALT, AST, gamma-GT, albumin, globulin)
and renal (blood creatinine, urea) functions in normal
mice. The oral mixture is an aqueous extract of four wellknown traditional Chinese medicinal herbs and consists
of Trichosanthes kirilowii Maxim., Paeonia lactiflora Pall.,Glycyrrhiza uranlensis Fisch., and Panax ginseng (red) CA Meyer in the proportion of 36%, 28%, 18%, and
18% respectively of the dry weight. These herbs have
been shown to have blood glucose lowering activity and
have been used for other traditional medicinal purposes.
The safety of the combination was evaluated in the
present study.
Methods: Experimental Balb/c mice were treated orally
via gastric tube with the extract at daily doses equivalent
to 1 and 10 times the recommended human dose for
8 weeks. Blood glucose and other biochemical profiles
were monitored at pre-treatment and monthly posttreatment
until killed.
Results: When compared to pre-treatment levels, the
blood glucose levels were significantly lower in treated
animals compared to those in the control group. At
the recommended TCM-D™ dose the levels in treated
animals were significantly lower than that of control
animals and at pre-treatment. When compared with
pre-treatment, the glucose levels were lowest at Week
8 of treatment, the mean levels being 111.23%, 83.32%
and 70.33% in control, and in animals given 1 x and
10 x the recommended TCM-D™ dosage respectively.
The blood glucose lowering effect was also associated
with a significant weight loss in treated animals. There
were transient increases in AST and ALT levels but these reverted to normal at Week 8 of treatment.
The levels of bilirubin, g-GT, albumin, creatinine
and blood urea were also not significantly different at
Week 8 from pre-treatment levels in all groups.
Conclusion: Even at 10 times the dosage recommended
for humans, TCM-D™ did not affect the liver and
renal functions of treated animals. Treated and control
animals remained healthy and normal throughout the
period of observation.

Background: We previously evaluated the biochemical
changes induced by the local product TCM for
diabetes (TCM-D™) on blood glucose levels and other
biochemical changes in normal mice fed orally with the
recommended human dose (30 ml/kg daily) and ten
times this dose for eight weeks. TCM-D™ is an aqueous
extract of the roots of Trichosanthes kirilowii Maxim,
Paeonia lactiflora Pall, Glycyrrhiza uranlensis Fisch. and
Panax ginseng Meyer (red) combined at the dry weight
proportions of 36%, 28%, 18% and 18% respectively.
The study showed that at these dosages the blood
glucose levels as well as the body weights in treated mice
were significantly reduced when compared with pretreatment
values and control animals. The present study
evaluated the effect of the extract in a mouse model of
Type 1 diabetes mellitus.
Methods: TCM-D™ extract was prepared as a 10x
concentrate and given orally at 0.3 ml/100 g and
1.5 ml/100 g to mice which were experimentally
induced diabetic with intraperitoneal injections of
streptozotocin (5 mg/100g) in sodium citrate (pH 4.5).
Control diabetic mice were dosed with extract diluent
(distilled water).
Results: At the doses studied the compound did not
show any significant lowering of the glucose levels in a
mouse model of Type 1 diabetes. There were significant
increases in the alanine aminotransferase (ALT) and
creatinine levels which were most likely due to the
treatment with the compound. There were no significant
changes in the aspartate aminotransferase (AST) and
blood urea levels due to the treatment. Neither was
there any significant effect on the weight of the treated
animals due to the treatment.
Conclusions: It is concluded that TCM-D™ did not
have any significant blood glucose lowering effect on
streptozotocin induced diabetic mice when fed orally at
1-5 times the recommended human dose. Further work
is needed to determine if the extract has any significant
effect in a mouse model with Type 2 diabetes mellitus.

INTRODUCTIONThe World Health Organization Quality of Life (WHOQOL-BREF) questionnaire is a 26-item questionnaire that evaluates 4 domains of quality of life (QoL), namely Physical, Psychological, Social Relationships and Environment. This study aimed to evaluate the validity and reliability of the WHOQOL-BREF among Singapore residents aged 21 and above.
MATERIALS AND METHODSWe recruited participants from the general population by using multistage cluster sampling and participants from 2 hospitals by using convenience sampling. Participants completed either English, Chinese or Malay versions of the WHOQOL-BREF and the EuroQoL 5 Dimension 5 Levels (EQ-5D-5L) questionnaires. Confirmatory factor analysis, known-group validity, internal consistency (Cronbach's alpha) and test-retest reliability using the intraclass correlation coefficient (ICC) were performed.
RESULTSData from 1316 participants were analysed (Chinese: 46.9%, Malay: 41.0% and Indian: 11.7%; 57.5% mean, mean standard deviation [SD, range] age: 51.9 [15.68, 24 to 90] years); 154 participants took part in the retest in various languages (English: 60, Chinese: 49 and Malay: 45). Tucker-Lewis Index (TLI) was 0.919, 0.913 and 0.909 for the English, Chinese and Malay versions, respectively. Cronbach's alpha exceeded 0.7 and ICC exceeded 0.4 for all domains in all language versions.
CONCLUSIONThe WHOQOL-BREF is valid and reliable for assessing QoL in Singapore. Model fit is reasonable with room for improvement.

Objective: A quick assessment tool for screening individuals with depression or anxiety is pertinent in mental-health set up. This study aims to validate the K10 and the K6 to screen patients with non-specific psychological distress in a Malaysian population. Methods: Translation of the questionnaire was done from English to Malay. Face validity was conducted on patients, and a pilot study was performed to assess the reliability of the K10 questionnaire. Fieldwork was conducted to determine the reliability and validity of the K10 questionnaire based on convenience sampling of healthy individuals and patients diagnosed with psychiatric illness. Malay version for K10 was administered to healthy participants (group without psychological distress) and patients on psychiatric clinic follow up (psychological distress). Data collection was done between August 2016 and September 2016. Result: A total of 94 subjects were recruited in the study, of which 32 formed the case group. The Cronbach’s alpha coefficients for K10 were 0.837(control) and 0.885 (case), as for K6 were 0.716 (control) and 0.859 (case). The total score of the K10 and the K6 clearly differentiated between the control and case groups (p<0.001). The area under the curve for K10 and K6 were 0.84 with 95% CI (0.81, 0.96) and 0.86 with 95% CI (0.77, 0.94) respectively. For K10, at the optimal cut-off score of 17, the sensitivity and specificity were 84.4% and 75.3% respectively while for K6, at the optimal cut-off score of 11, the sensitivity and specificity were 78.1% and 75.8%, respectively. Conclusion: The Malay version of the K10 and the K6 are reliable and valid to be used for screening patients with non-specific psychological distress in a Malaysian population. Kessler psychological distress scale has minimal items and yet this Kessler psychological distress scales have minimal items and yet are an effective screening tool.

Sarcopenia, which is characterized by progressive and generalized loss of skeletal muscle mass and strength, has been well described to be associated with numerous poor postoperative outcomes, such as increased perioperative mortality, postoperative sepsis, prolonged length of stay, increased cost of care, decreased functional outcome, and poorer oncological outcomes in cancer surgery. Multimodal prehabilitation, as a concept that involves boosting and optimizing the preoperative condition of a patient prior to the upcoming stressors of a surgical procedure, has the purported benefits of reversing the effects of sarcopenia, shortening hospitalization, improving the rate of return to bowel activity, reducing the costs of hospitalization, and improving quality of life. This review aims to present the current literature surrounding the concept of sarcopenia, its implications pertaining to colorectal cancer and surgery, a summary of studied multimodal prehabilitation interventions, and potential future advances in the management of sarcopenia.
