OBJECTIVE: To evaluate the effectiveness of the pharmacist-managed DMTAC program in improving glycaemic control, lipid parameters and patients' medication adherence.
METHOD: A retrospective study among patients enrolled in the DMTAC program was conducted between September 2007 and December 2008. Data was included from patients with a glycosylated haemoglobin (HbA1c) >8% and who had completed eight visits with the pharmacists. Medical records and DMTAC forms that provided patients' demographics, medication regimens, adherence and laboratory parameters as well as pharmacists' interventions were reviewed. HbA1c, fasting blood glucose (FBG), low-density lipoprotein cholesterol (LDL), triglycerides (TG) and high-density lipoprotein cholesterol (HDL) were evaluated. Documented data of patients' adherence to medication regimen [Modified Morisky Medication Adherence Score (MMMAS); high adherence if score >8, medium adherence if score 6 to <8 and low adherence if score <6] was also evaluated.
RESULTS: A total of 43 patients (53.5% females; 46.5% Malays, 44.2% Chinese and 9.3% Indians) were included in the analysis. A mean reduction in HbA1c of 1.73% (p<0.001), mean reduction in FBG of 2.65mmol/l (p=0.01) and mean reduction in LDL cholesterol of 0.38mmol/l (p=0.007) were achieved. The difference in TG and HDL cholesterol were not significant. Patients' adherence to medication regimens improved significantly with an increase in the mean MMMAS score from 7.00 to 10.84 (p<0.001) after completion of the DMTAC program.
CONCLUSION: The pharmacist-managed DMTAC program resulted in significant improvements in HbA1c, glucose and LDL cholesterol levels as well as medication adherence in patients with diabetes.
METHODS: Five electronic databases were searched for studies involving tocilizumab, dexamethasone, and methylprednisolone in treating COVID-19. We included case-control and randomized or partially randomized trials. Meta-regression for patient baseline characteristics, co-medications, and tocilizumab dose regimens was performed to identify contributing factors to drug efficacy.
RESULTS: Thirteen randomized controlled trials (RCTs) and twenty-four case-control studies were included in our meta-analysis involving 18,702 patients. Meta-analysis among the RCTs showed that a summary estimate favoring mortality reduction (OR 0.71, 95%CI 0.55 - 0.92) contributed mainly by tocilizumab and dexamethasone. Among case-control studies, meta-analysis showed mortality reduction (OR 0.52, 95%CI 0.36 - 0.75) contributed by tocilizumab and tocilizumab-methylprednisolone combination. Methylprednisolone alone did not reduce mortality except for one study involving high dose pulse therapy. Meta-analysis also found that all three drugs did not significantly reduce mechanical ventilation (OR 0.72, 95%CI 0.32 - 1.60).
CONCLUSION: Tocilizumab and dexamethasone emerge as viable options in reducing mortality in severe COVID-19 patients. A tocilizumab-corticosteroid combination strategy may improve therapeutic outcome in cases where single therapy fails.
PURPOSE: This study aims to compare the cost, medication adherence and glycaemic control of utilizing POMs versus usual dispensing.
METHODS: Prospective randomized controlled study was conducted among diabetic patients that required monthly medication refill in the Outpatient Pharmacy in 2017. Patients who consented were equally divided into POMs and control groups. Both groups brought excess medications from home at week-0 and week-12. Patients in the POMs group brought excess medications monthly and sufficient amount of drugs were added until the next refill date. Drugs were dispensed as usual in the control group. Total cost consisting of the cost of drugs, staff and building was calculated. Glycosylated haemoglobin (HbA1c) was measured at baseline and week-12. Adherence was measured based on pill counting.
RESULTS: Thirty patients aged 56.77 ± 14.67 years with 13.37 ± 7.36 years of diabetes participated. Baseline characteristics were similar between the groups. POMs minimized the total cost by 38.96% which translated to a cost saving of USD 42.76 ± 6.98, significantly different versus USD 0.02 ± 0.52 in the control group, p = 0.025. Mean HbA1c reduced significantly (-0.79%, p = 0.016) in the POMs group but not significant in the control group (-0.11%, p = 0.740). Medication adherence improved significantly in both groups at week-12 (p
OBJECTIVE: This study investigates the antidiabetic and antioxidant effects of M. latifolia bark extracts, fractions, and isolated constituents.
MATERIALS AND METHODS: Melicope latifolia extracts (hexane, chloroform, and methanol), fractions, and isolated constituents with varying concentrations (0.078-10 mg/mL) were subjected to in vitro α-amylase and dipeptidyl peptidase-4 (DPP-4) inhibitory assay. Molecular docking was performed to study the binding mechanism of active compounds towards α-amylase and DPP-4 enzymes. The antioxidant activity of M. latifolia fractions and compounds were determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging and β-carotene bleaching assays.
RESULTS: Melicope latifolia chloroform extract showed the highest antidiabetic activity (α-amylase IC50: 1464.32 μg/mL; DPP-4 IC50: 221.58 μg/mL). Fractionation of chloroform extract yielded four major fractions (CF1-CF4) whereby CF3 showed the highest antidiabetic activity (α-amylase IC50: 397.68 μg/mL; DPP-4 IC50: 37.16 μg/mL) and resulted in β-sitosterol (1), halfordin (2), methyl p-coumarate (3), and protocatechuic acid (4). Isolation of compounds 2-4 from the species and their DPP-4 inhibitory were reported for the first time. Compound 2 showed the highest α-amylase (IC50: 197.53 μM) and β-carotene (88.48%) inhibition, and formed the highest number of molecular interactions with critical amino acid residues of α-amylase. The highest DPP-4 inhibition was exhibited by compound 3 (IC50: 911.44 μM).
DISCUSSION AND CONCLUSIONS: The in vitro and in silico analyses indicated the potential of M. latifolia as an alternative source of α-amylase and DPP-4 inhibitors. Further pharmacological studies on the compounds are recommended.
AIM: To develop and validate a patient diabetes knowledge questionnaire (PDKQ) to assess knowledge of diabetes mellitus patients.
METHODS: The development of the PDKQ questionnaire involved three phases: item development, content validation, and reliability testing. In the item development phase, the initial draft of the PDKQ, comprising a multiple-choice answer questionnaire was developed. The content validation phase comprised two stages. Firstly, ten experts participated in the expert validation process, followed by face validation involving six patients. In the final phase, test-retest analysis was performed among diabetes mellitus patients to assess reliability.
RESULTS: The first draft of PDKQ consisted of 11 patient characteristics items and 37 items of multiple choices questions. During the expert validation, three items were eliminated due to low clarity, and an additional six items were removed as they were deemed irrelevant or unimportant. During the face validation, three patients' characteristic items and eight multiple-choice questions were excluded due to a content validity index of less than 0.83. In the test-retest phase, 36 subjects responded to 8 items pertaining to patients' characteristics and 20 multiple-choice questions. The test-retest analysis yielded an intraclass correlation coefficient of 0.88, indicating good reliability.
CONCLUSION: The 20-item PDKQ is a reliable and robust tool in assessing the knowledge of diabetes mellitus patients in Malaysia. Its implementation allows standardized assessment of diabetic patients' knowledge levels, enabling targeted interventions to empower patients and optimize diabetes care practices.
AIM: To assess the impact DMTAC on glycemic control and the difference in glycemic control between hospital and health clinic settings as well as defaulter and non-defaulter. In addition, the impact of pharmacist's interventions, DMTAC follow-up frequencies, and duration of diabetes on glycemic control were also determined.
METHODS: A retrospective study was conducted among diabetes patients under DMTAC care between January 2019 and June 2020 in five hospitals and 23 primary health clinics. Patients' demographics data, treatment regimens, frequencies of DMTAC visits, defaulter (absent from DMTAC visits) and types of pharmacists' intervention were retrieved from patients' medical records and electronic database. HbA1c was collected at baseline, 4-6 months (post-1), and 8-12 months (post-2).
RESULTS: We included 956 patients, of which 60% were females with a median age of 58.0 (IQR: 5.0) years. Overall, the HbA1c reduced significantly from baseline (median: 10.2, IQR: 3.0) to post-1 (median: 8.8, IQR: 2.7) and post-2 (median: 8.3, IQR: 2.6%) (p
