    PMID: 20807297 DOI: 10.1111/j.1365-2753.2010.01367.x
    RATIONALE, AIMS AND OBJECTIVES: To evaluate the impact of clinical audit on diabetes care provided to type 2 diabetic patients attending our hospital general medical clinics.
    METHODS: Performances on diabetes-related process measures and intermediate outcome measures were evaluated through structured review of outpatient medical records. The results were fed back to the doctors and measures were implemented to improve care. The performance indicators were re-evaluated 2 years later to complete the audit cycle.
    RESULTS: Annual testing rates improved for HbA1c (68.4% vs. 87.4%; P < 0.001) and lipid profile (91.8% vs. 97%; P = 0.027). Enquiry on smoking improved from 45.9% to 82.3% (P < 0.001), eye screening rates from 68.9% to 78.8% (P = 0.020) and foot examinations from 22.4% to 64.1% (P < 0.001). Prescription rates for insulin increased from 17.3% to 31.8% (P = 0.001) and statin from 83.2% to 94.4% (P < 0.001). The use of aspirin (80.6% vs. 83.8%; P =0.402) and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (92.3% vs. 88.9%; P = 0.239) remained high in both cycles. More patients achieved targets for HbA1c < 7% (38% vs. 26%; P = 0.006), blood pressure < 130/80 mmHg (43% vs. 32%; P = 0.071) and low-density lipoprotein cholesterol < 2.6 mmol/L (71% vs. 52%; P <0.001).
    CONCLUSION: Clinical audit is a useful tool in improving diabetes care.

  2. Fulltext Risk Factors Associated with Sarcopenia Among Independently Mobile, Institutionalised Older People in the Klang Valley of Malaysia: A Cross-Sectional Study
    Yap SF, Boo NY, Pramod DS, Thaw Z, Liew SF, Woo LF, et al.
    Malays J Med Sci, 2020 Mar;27(2):120-128.
    PMID: 32788848 MyJurnal DOI: 10.21315/mjms2020.27.2.13
    Background: Studies on sarcopenia among Malaysian older people (OP ≥ 60 years of age) living in the community but not in long-term care (LTC) homes have been reported previously. This study aimed to determine the prevalence of sarcopenia and its risk factors in OP in Malaysian LTC homes.

    Methods: This cross-sectional study was conducted with 202 independently mobile OP (males 32%) in seven LTC homes in the Klang Valley of Malaysia. Trained personnel measured their anthropometrics, body composition, gait speed, hand grip strength and timed up-and-go (TUG) duration. Criteria of the European Working Group on Sarcopenia in Older People (EWGSOP) and of the Asian Working Group for Sarcopenia were used to identify the presence of sarcopenia. The mini-nutritional assessment (MNA) was used to determine their nutritional status. Additionally, logistic regression analysis was performed to identify significant risk factors associated with pre-sarcopenia/sarcopenia.

    Results: Pre-sarcopenia/sarcopenia was detected in 103 (51%) OP. The significant risk factors were body mass index (BMI, weight/height2; adjusted odds ratio [AOR] = 0.44, P < 0.001), percentage of body fat (PBF; AOR = 1.26, P < 0.001), age group (≥ 80 years; AOR = 3.63, P = 0.025) and 'at risk of malnutrition' status (AOR = 2.63, P = 0.049).

    Conclusion: Sarcopenia is common among OP in LCT homes. The risk increases with decreasing BMI, increasing PBF, age ≥ 80 years and suboptimal nutrition status.

  3. Fulltext Anticancer mechanisms of Strobilanthes crispa Blume hexane extract on liver and breast cancer cell lines

    Cancer is a major public health concern not only in developed countries, but also in developing countries. It is one of the leading causes of mortality worldwide. However, current treatments may cause severe side effects and harm. Therefore, recent research has been focused on identifying alternative therapeutic agents extracted from plant-based sources in order to develop novel treatment options for cancer. Strobilanthes crispa Blume is a plant native to countries including Madagascar and Indonesia. It has been used as an anti-diabetic, diuretic and laxative in traditional folk medicine. Furthermore, S. crispa has potential in treating cancer, as evidenced in previous studies. In the present study, the cytotoxic and apoptotic activities of S. crispa crude extracts were investigated in liver and breast cancer cell lines. Hexane, ethyl acetate, chloroform, methanol and water extracts prepared from the leaves, and stems of S. crispa were evaluated for their cytotoxicity on HepG-2 and MDA-MB-231 cells using an MTT assay. The anti-proliferative properties of stem hexane (SH) extract on both cell lines were analysed using cell doubling time determination and cell cycle analysis, while the apoptogenic properties was determined through the detection of caspase-8. Among the extracts tested, SH extract exhibited the lowest half maximal inhibitory concentrations in both the cell lines. The SH extract induced morphological changes in HepG-2 and MDA-MB-231 cells, and significantly delayed cell population doubling time. Furthermore, it altered cell cycle profile and significantly increased caspase-8 activity in HepG-2 cells, but not in MDA-MB-231 cells. In conclusion, the SH extract of S. crispa possesses potent anticancer properties and may be a suitable chemotherapeutic target.
