This study was conducted to determine the cholesterol and alpha-tocopherol contents of 20 marine fish and four other seafood from the Straits of Malacca. Cholesterol and alphatocopherol contents of the fish and other seafood were determined using high-performance liquid chromatography. The results showed that most of the fish contained low amounts of cholesterol, except sixbar grouper (Epinephelus fasciatus), long-tailed butterfly ray (Gymnura sp.), yellowstripe scad (Selaroides leptolepis), cuttlefish (Sepia officinalis), large-scale tongue sole (Cynoglossus arel), and longtail shad (Hilsa macrura) that contained high amounts of cholesterol (119.39-353.97 mg/100 g wet samples). Indian mackerel (Rastrelliger kanagurta), giant seaperch (Lates calcarifer), prawn (Metapenaeus affinis), and moonfish (Trachinotus blochii) had high alpha-tocopherol contents (462-989 μg/100 g wet sample). Regular consumption of fish and other seafood is highly recommended partly due to the high alphatocopherol content. Due to the high cholesterol in certain types of fish, consumption of the fish fillets of sixbar grouper, long-tailed butterfly ray, yellowstripe scad, cuttlefish, and large scale tongue sole should be < 100 g per day and < 50 per day for longtail shad. Validation of the analytical method also showed a high accuracy and reproducibility of the HPLC method.

Oncolytic virotherapy is a therapeutic approach that uses replication-competent viruses to kill cancers. The ability of oncolytic viruses to selectively replicate in cancer cells leads to direct cell lysis and induction of anticancer immune response. Like other anticancer therapies, oncolytic virotherapy has several limitations such as viral delivery to the target, penetration into the tumor mass, and antiviral immune responses. This review provides an insight into the different characteristics of oncolytic viruses (natural and genetically modified) that contribute to effective applications of oncolytic virotherapy in preclinical and clinical trials, and strategies to overcome the limitations. The potential of oncolytic virotherapy combining with other conventional treatments or cancer immunotherapies involving immune checkpoint inhibitors and CAR-T therapy could form part of future multimodality treatment strategies.

PMID: 23441979 DOI: 10.1111/jcpt.12027

Pharmacists have the knowledge regarding optimal use of medications and the ability to influence physician prescribing. Successful interventions by a pharmacist to implement cardioprotective medications to a coronary artery disease patient's regimen would not only improve the patient's quality of care but may also increase his or her likelihood of survival. Therefore, the aim of this study was to (i) evaluate the effectiveness of pharmacist initiated interventions in increasing the prescription rates of acute coronary syndrome (ACS) secondary prevention pharmacotherapy at discharge, and to (ii) evaluate the acceptance rate of these interventions by prescribers.

Patients may not comply with antibiotic instructions because they do not understand them. The aim of this study was to assess outpatients' ability to comprehend their antibiotic prescription labels. Two hundred and five subjects on oral antibiotic regimens from an outpatient clinic and pharmacy of a district hospital were selected in this survey. All patients were interviewed by trained clinical pharmacy students. They were asked to read the labels and then how they would take their antibiotics. The results show that 119 (58.1%) patients could interpret the label. Forty-nine (23.9%) patients knew the name of antibiotics and interpreted the directions of use correctly. One hundred sixteen (56.6%) subjects were able to recall the auxiliary information. However, only 44 (21.4%) patients were able to comprehend complete antibiotic instruction. This study demonstrates that a significant proportion of patients could not interpret the labeling instruction. The comprehension level of patients was low and significantly associated (P < 0.05) with the ability of patient to read the label contents. These observations illustrate the need for physicians and pharmacists to provide antibiotic instructions and review these instructions with the patient.

PMID: 32733559 DOI: 10.1155/2020/8029721

MicroRNAs (miRNAs) are small noncoding RNAs that function at the posttranscriptional level in the cellular regulation process. miRNA expression exerts vital effects on cell growth such as cell proliferation and survival. In cancers, miRNAs have been shown to initiate carcinogenesis, where overexpression of oncogenic miRNAs (oncomiRs) or reduced expression of tumor suppressor miRNAs has been reported. In this review, we discuss the involvement of miRNAs in tumorigenesis, the role of synthetic miRNAs as either mimics or antagomirs to overcome cancer growth, miRNA delivery, and approaches to enhance their therapeutic potentials.
Fulltext Newcastle disease virus degrades HIF-1α through proteasomal pathways independent of VHL and p53

Newcastle disease virus (NDV) is a candidate agent for oncolytic virotherapy. Despite its potential, the exact mechanism of its oncolysis is still not known. Recently, we reported that NDV exhibited an increased oncolytic activity in hypoxic cancer cells. These types of cells negatively affect therapeutic outcome by overexpressing pro-survival genes under the control of the hypoxia-inducible factor (HIF). HIF-1 is a heterodimeric transcriptional factor consisting of a regulated α (HIF-1α) and a constitutive β subunit (HIF-1β). To investigate the effects of NDV infection on HIF-1α in cancer cells, the osteosarcoma (Saos-2), breast carcinoma (MCF-7), colon carcinoma (HCT116) and fibrosarcoma (HT1080) cell lines were used in the present study. Data obtained showed that a velogenic NDV infection diminished hypoxia-induced HIF-1α accumulation, leading to a decreased activation of its downstream target gene, carbonic anhydrase 9. This NDV-induced downregulation of HIF-1α occurred post-translationally and was partially abrogated by proteasomal inhibition. The process appeared to be independent of the tumour suppressor protein p53. These data revealed a correlation between NDV infection and HIF-1α downregulation, which highlights NDV as a promising agent to eliminate hypoxic cancer cells.
Bortezomib attenuates HIF-1- but not HIF-2-mediated transcriptional activation

Abd-Aziz N, Stanbridge EJ, Shafee N

PMID: 26622817

Bortezomib is the first proteasomal inhibitor (PI) to be used therapeutically for treating relapse cases of multiple myeloma and mantle cell lymphoma. A proposed mechanism for its action is that it prevents the proteasomal degradation of proapoptotic proteins, leading to enhanced apoptosis. Although the α subunit of hypoxia-inducible factor (HIF)-1 is not degraded with bortezomib treatment, the heterodimeric HIF-1 fails to transactivate target genes. HIF-1 and HIF-2 are related hypoxia-inducible transcription factors that are important for the survival of hypoxic tumor cells. The majority of reports have focused on the effects of bortezomib on the transcriptional activities of HIF-1, but not HIF-2. The present study investigated the effects of bortezomib on HIF-2 activity in cancer cells with different levels of HIF-1α and HIF-2α subunits. HIF-α subunit levels were detected using specific antibodies, while HIF transcriptional activities were evaluated using immunodetection, reverse transcription-polymerase chain reaction and luciferase reporter assay. Bortezomib treatment was found to suppress the transcription and expression of CA9, a HIF-1-specific target gene; however, it had minimal effects on EPO and GLUT-1, which are target genes of both HIF-1 and HIF-2. These data suggest that bortezomib attenuates the transcriptional activity only of HIF-1, and not HIF-2. This novel finding on the lack of an inhibitory effect of bortezomib on HIF-2 transcriptional activity has implications for the improvement of design and treatment modalities of bortezomib and other PI drugs.
Fulltext Does the duration of smoking cessation have an impact on hospital admission and health-related quality of life amongst COPD patients?

Abu Hassan H, Abd Aziz N, Hassan Y, Hassan F

Int J Chron Obstruct Pulmon Dis, 2014;9:493-8.
PMID: 24868154 DOI: 10.2147/COPD.S56637

BACKGROUND: Lack of awareness among ex-smokers on the benefits of sustaining smoking cessation may be the main cause of their smoking relapse. This study explored health-related quality of life (HRQoL) and hospital admission amongst chronic obstructive pulmonary disease (COPD) patients according to the duration of smoking cessation.
MATERIALS AND METHODS: This study recruited COPD patients from a chest clinic who agreed to participate in a medication therapy-adherence program from January to June 2013. They were interviewed during their visits to obtain information regarding their smoking history and HRQoL. They were divided into three groups according to smoking status (sustained quitters, quit ≥5 years; quitters, quit <5 years; and smokers, smoking at least one cigarette/day). The effects of the duration of cessation on HRQoL and hospital admission were analyzed using a multinomial logistic model.
RESULTS: A total of 117 participants with moderate COPD met the inclusion criteria, who were comprised of 41 sustained quitters, 40 quitters, and 36 smokers. Several features were similar across the groups. Most of them were married elderly men (aged >64 years) with low-to-middle level of education, who smoked more than 33 cigarettes per day and had high levels of adherence to the medication regimen. The results showed that sustained quitters were less likely to have respiratory symptoms (cough, phlegm and dyspnea) than smokers (odds ratio 0.02, confidence interval 0-0.12; P<0.001). The hospital admission rate per year was increased in quitters compared to smokers (odds ratio 4.5, confidence interval 1.91-10.59; P<0.005).
CONCLUSION: A longer duration of quitting smoking will increase the benefits to COPD patients, even if they experience increased episodic respiratory symptoms in the early period of the cessation. Thus, the findings of this study show the benefits of early smoking cessation.

Drug use and dosing in chronic kidney disease

Hassan Y, Al-Ramahi R, Abd Aziz N, Ghazali R

Ann Acad Med Singap, 2009 Dec;38(12):1095-103.
PMID: 20052447

One of the most important drug-related problems in patients with chronic kidney disease (CKD) is medication dosing errors. Many medications and their metabolites are eliminated through the kidney. Thus, adequate renal function is important to avoid toxicity. Patients with renal impairment often have alterations in their pharmacokinetic and pharmacodynamic parameters. The clearance of drugs eliminated primarily by renal filtration is decreased by renal disease. Therefore, special consideration should be taken when these drugs are prescribed to patients with impaired renal function. Despite the importance of dosage adjustment in patients with CKD, such adjustments are sometimes ignored. Physicians and pharmacists can work together to accomplish safe drug prescribing. This task can be complex and require a stepwise approach to ensure effectiveness, minimise further damage and prevent drug nephrotoxicity.
Patients' adherence to secondary prevention pharmacotherapy after acute coronary syndromes

Kassab Y, Hassan Y, Abd Aziz N, Ismail O, AbdulRazzaq H

Int J Clin Pharm, 2013 Apr;35(2):275-80.
PMID: 23283596 DOI: 10.1007/s11096-012-9735-y

BACKGROUND: Secondary prevention pharmacotherapy improves outcomes after acute coronary syndrome (ACS). However, poor medication adherence is common, and various factors play a role in adherence.
OBJECTIVES: The purpose of this study was to evaluate patients' level of adherence to evidence-based therapies at an average of 6 months after discharge for acs and to identify factors associated with self-reported non-adherence.
SETTING: This prospective study was conducted in the outpatient cardiac clinics of Hospital Pulau Pinang, located in Penang Island, a northern state in Malaysia.
METHOD: A random sample of ACS patients (n = 190) who had been discharged on a regimen of secondary preventive medications were included in this study. Six months after discharge and during their scheduled follow-up appointments to cardiac clinics, patients were interviewed using the translated eight-item Morisky Medication Adherence Scale.
MAIN OUTCOME MEASURE: self-reported patients' adherence to medication.
RESULTS: Six months following their hospital discharge, only 35 patients (18.4 %) reported high adherence. Medium adherence was reported in majority of patients (51.1 %). Low adherence was reported in 58 patients (30.5 %). Forgetfulness was the most frequently reported reason for patients' non-adherence to their medications (23.2 %). Furthermore, this study identified 5 factors-namely age, employment status, ACS subtypes, number of comorbidities, and number of prescription medications per day-that may influence Patients' level of adherence to the prescribed regimens.
CONCLUSIONS: Our findings revealed a problem of non-adherence to secondary prevention medications among patients with ACS in Malaysia. Furthermore, this study demonstrates that older patients, unemployed patients, patients with more comorbid conditions, and those receiving multiple medications are less likely to adhere to their prescribed medications 6 months after hospital discharge.

Int J Clin Pharm, 2020 Apr;42(2):527-538.
PMID: 32144611 DOI: 10.1007/s11096-020-01005-4

Background The appropriateness of antibiotics is the basis for improving the survival of patients with sepsis. Objective This study aimed to determine the appropriateness of empirical antibiotics, reasons for non-appropriate empirical antibiotics, risk factors of mortality, length of stay in intensive care unit (ICU-LOS) and Acute Physiology And Chronic Health Evaluation II (APACHE II) score predictors in adult patients with sepsis. Setting An adult ICU of a tertiary hospital in Malaysia. Methods A retrospective cohort study was conducted amongst patients with sepsis. Data were retrieved from the patients' files and computer system. Each case was reviewed for the appropriateness of empirical antibiotics based on ICU local guidelines, bacterial sensitivity, dose, frequency, creatinine clearance and time of administration of empirical antibiotics. Multivariable logistic and Cox regression modelling were performed to compute the adjusted association of receiving appropriate or inappropriate empirical antibiotics with ICU mortality. Multivariable linear regression modelling was performed using ICU-LOS and APACHE II scores. Main outcome measures were ICU mortality, severity score (APACHE II scores) and ICU-LOS. Results The total mortality rate amongst the 228 adult ICU patients was 84.6%. Males showed a higher mortality rate (119 [52.2%]) than females (74 [32.5%]). Inappropriate empirical antibiotics were significantly associated with mortality and ICU-LOS (P
Implementation of video modeling in the occupational therapy intervention process for children and adolescents with special needs: A scoping review

Occup Ther Health Care, 2021 Apr;35(2):227-244.
PMID: 33511894 DOI: 10.1080/07380577.2021.1876967

This scoping review explores the implementation of video modeling (VM) by occupational therapists during the intervention process for children and adolescents with special needs. Four primary electronic databases were used to conduct the scoping review: PubMed, Scopus, CINAHL, and Proquest (Nursing and Allied Health). Research methodologies by Arksey and O'Malley were used as a framework to perform the review process. From the review, two themes emerged: (1) implementing VM by occupational therapists during the intervention process can successfully improve a client's desired skills; (2) VM can be applied through several types of technologies. The findings support occupational therapists' use of VM during interventions to positively enhance and promote desired skills among children and adolescents with special needs. Also, it can be incorporated into technological devices to suit a client's specific needs.

Endometrial cancer (EC) has been found to have a strong association with overweight and obesity. The aim of this study was to evaluate the link between metabolic syndrome and EC among patients. A total of 119 patients with histologically confirmed EC were recruited. About 102 cases of endometrioid carcinoma (Type I) and serous (n = 7), clear cell (n = 3) and carcinosarcoma (n = 7) were the Type II. Metabolic syndrome was significantly associated with increased risk of Type I EC (OR = 3.43, 95% CI = 1.12-10.46, p .05). Metabolic syndrome was positively associated with an increased risk of Type I EC with obesity being the most influential risk factor.Impact statementWhat already known on this subject? Endometrial cancer (EC) is one of the most prevalent cancers worldwide and have a strong association with overweight and obesity of at least 40%, but there is conflicting evidence of an association of EC with metabolic syndrome (MS).What result of this study add? This study evaluated the link between EC and MS, such as high blood pressure, BMI, fasting blood sugar, triglyceride, Hyper Density Lipoprotein (HDL).What implications are of these findings for clinical practice & further research? Type I EC had and association with MS with obesity is the most potent risk factor. As the prevalence of metabolic syndrome is alarmingly high among adult Malaysians, the incidence of EC is projected to increase in the coming years. Proactive preventative measures and intervention essential for reducing the incidence of endometrial cancers. Future research to clarify the association between metabolic syndrome and endometrial cancer survival and to investigate other lifestyle factors that may affect the prognosis is needed.
Fulltext Role of microRNAs in antiviral responses to dengue infection

Wong RR, Abd-Aziz N, Affendi S, Poh CL

Dengue virus (DENV) is the etiological agent of dengue fever. Severe dengue could be fatal and there is currently no effective antiviral agent or vaccine. The only licensed vaccine, Dengvaxia, has low efficacy against serotypes 1 and 2. Cellular miRNAs are post-transcriptional regulators that could play a role in direct regulation of viral genes. Host miRNA expressions could either promote or repress viral replications. Induction of some cellular miRNAs could help the virus to evade the host immune response by suppressing the IFN-α/β signaling pathway while others could upregulate IFN-α/β production and inhibit the viral infection. Understanding miRNA expressions and functions during dengue infections would provide insights into the development of miRNA-based therapeutics which could be strategized to act either as miRNA antagonists or miRNA mimics. The known mechanisms of how miRNAs impact DENV replication are diverse. They could suppress DENV multiplication by directly binding to the viral genome, resulting in translational repression. Other miRNA actions include modulation of host factors. In addition, miRNAs that could modulate immunopathogenesis are discussed. Major hurdles lie in the development of chemical modifications and delivery systems for in vivo delivery. Nevertheless, advancement in miRNA formulations and delivery systems hold great promise for the therapeutic potential of miRNA-based therapy, as supported by Miravirsen for treatment of Hepatitis C infection which has successfully completed phase II clinical trial.
Fulltext A Retrospective Analysis of Spontaneous Adverse Drug Reactions Reports Relating to Paediatric Patients

Rosli R, Ming LC, Abd Aziz N, Manan MM

PLoS One, 2016;11(6):e0155385.
PMID: 27249414 DOI: 10.1371/journal.pone.0155385

BACKGROUND: Spontaneous reporting on adverse drug reactions (ADR) has been established in Malaysia since 1987, and although these reports are monitored by the Malaysia drug monitoring authority, the National Pharmaceutical Control Bureau, information about ADRs in the paediatric patient population still remains unexplored. The aims of this study, therefore, were to characterize the ADRs reported in respect to the Malaysian paediatric population and to relate the data to specific paediatric age groups.
METHODS: Data on all ADRs reported to the National Pharmaceutical Control Bureau between 2000 and 2013 for individuals aged from birth to 17 years old were analysed with respect to age and gender, type of reporter, suspected medicines (using the Anatomical Therapeutic Chemical classification), category of ADR (according to system organ class) as well as the severity of the ADR.
RESULTS: In total, 11,523 ADR reports corresponding to 22,237 ADRs were analysed, with half of these reporting one ADR per report. Vaccines comprised 55.7% of the 11,523 ADR reports with the remaining being drug related ADRs. Overall, 63.9% of ADRs were reported for paediatric patients between 12 and 17 years of age, with the majority of ADRs reported in females (70.7%). The most common ADRs reported were from the following system organ classes: application site disorders (32.2%), skin and appendages disorders (20.6%), body as a whole general disorders (12.8%) and central and peripheral nervous system disorders (11.2%). Meanwhile, ADRs in respect to anti-infectives for systemic use (2194/5106; 43.0%) were the most frequently reported across all age groups, followed by drugs from the nervous system (1095/5106; 21.4%). Only 0.28% of the ADR cases were reported as fatal. A large proportion of the reports were received from healthcare providers in government health facilities.
DISCUSSION: ADR reports concerning vaccines and anti-infectives were the most commonly reported in children, and are mainly seen in adolescents, with most of the ADRs manifesting in skin reactions. The majority of the ADR reports were received from nurses in the public sector, reporting ADRs associated with vaccine administration. The low fatality rate of ADR cases reported could potentially be caused by reporting bias due to the very low reporting percentage from the private healthcare institutions. This study indicates that ADR rates among Malaysian children are higher than in developed countries. Constant ADR reporting and monitoring, especially in respect to paediatric patients, should be undertaken to ensure their safety.

Abd-Aziz N, Lee MF, Ong SK, Poh CL

Virology, 2024 Jan;589:109941.
PMID: 37984152 DOI: 10.1016/j.virol.2023.109941

The hand, food, and mouth disease (HFMD) is primarily caused by Enterovirus A71 (EV-A71). EV-A71 outbreaks in the Asia Pacific have been associated with severe neurological disease and high fatalities. Currently, there are no FDA-approved antivirals for the treatment of EV-A71 infections. In this study, the SP81 peptide, derived from the VP1 capsid protein of EV-A71 was shown to be a promising antiviral candidate for the treatment of EV-A71 infections. SP81 peptide was non-toxic to RD cells up to 45 μM, with a half-maximal cytotoxic concentration (CC50) of 90.32 μM. SP81 peptide exerted antiviral effects during the pre- and post-infection stages with 50% inhibitory concentrations (IC50) of 4.529 μM and 1.192 μM, respectively. Direct virus inactivation of EV-A71 by the SP81 peptide was also observed with an IC50 of 8.076 μM. Additionally, the SP81 peptide exhibited direct virus inactivation of EV-A71 at 95% upon the addition of the SP81 peptide within 5 min. This study showed that the SP81 peptide exhibited significant inhibition of EV-A71 and could serve as a promising antiviral agent for further clinical development against EV-A71 infections.
Fulltext Care for post-stroke patients at Malaysian public health centres: self-reported practices of family medicine specialists

Abdul Aziz AF, Mohd Nordin NA, Abd Aziz N, Abdullah S, Sulong S, Aljunid SM

BMC Fam Pract, 2014;15:40.
PMID: 24580779 DOI: 10.1186/1471-2296-15-40

BACKGROUND: Provision of post stroke care in developing countries is hampered by discoordination of services and limited access to specialised care. Albeit shortcomings, primary care continues to provide post-stroke services in less than favourable circumstances. This paper aimed to review provision of post-stroke care and related problems among Family Medicine Specialists managing public primary health care services.
METHODS: A semi-structured questionnaire was distributed to 121 Family Physicians servicing public funded health centres in a pilot survey focused on improving post stroke care provision at community level. The questionnaire assessed respondents background and practice details i.e. estimated stroke care burden, current service provision and opinion on service improvement. Means and frequencies described quantitative data. For qualitative data, constant comparison method was used until saturation of themes was reached.
RESULTS: Response rate of 48.8% was obtained. For every 100 patients seen at public healthcentres each month, 2 patients have stroke. Median number of stroke patients seen per month is 5 (IQR 2-10). 57.6% of respondents estimated total stroke patients treated per year at each centre was less than 40 patients. 72.4% lacked a standard care plan although 96.6% agreed one was needed. Patients seen were: discharged from tertiary care (88.1%), shared care plan with specialists (67.8%) and patients who developed stroke during follow up at primary care (64.4%). Follow-ups were done at 8-12 weekly intervals (60.3%) with 3.4% on 'as needed' basis. Referrals ranked in order of frequency were to physiotherapy services, dietitian and speech and language pathologists in public facilities. The FMS' perceived 4 important 'needs' in managing stroke patients at primary care level; access to rehabilitation services, coordinated care between tertiary centres and primary care using multidisciplinary care approach, a standardized guideline and family and caregiver support.
CONCLUSIONS: Post discharge stroke care guidelines and access to rehabilitation services at primary care is needed for post stroke patients residing at home in the community.

Biomed Res Int, 2013;2013:284329.
PMID: 23509703 DOI: 10.1155/2013/284329

This study was conducted to quantitatively determine the fatty acid contents of 20 species of marine fish and four species of shellfish from Straits of Malacca. Most samples contained fairly high amounts of polyunsaturated fatty acids (PUFAs), especially alpha-linolenic acid (ALA, C18:3 n3), eicosapentaenoic acid (EPA, C20:5 n3), and docosahexaenoic acid (DHA, C22:6 n3). Longtail shad, yellowstripe scad, and moonfish contained significantly higher (P < 0.05) amounts of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA), respectively. Meanwhile, fringescale sardinella, malabar red snapper, black pomfret, Japanese threadfin bream, giant seaperch, and sixbar grouper showed considerably high content (537.2-944.1 mg/100 g wet sample) of desirable omega-3 fatty acids. The polyunsaturated-fatty-acids/saturated-fatty-acids (P/S) ratios for most samples were higher than that of Menhaden oil (P/S = 0.58), a recommended PUFA supplement which may help to lower blood pressure. Yellowstripe scad (highest DHA, ω - 3/ω - 6 = 6.4, P/S = 1.7), moonfish (highest ALA, ω - 3/ω - 6 = 1.9, P/S = 1.0), and longtail shad (highest EPA, ω - 3/ω - 6 = 0.8, P/S = 0.4) were the samples with an outstandingly desirable overall composition of fatty acids. Overall, the marine fish and shellfish from the area contained good composition of fatty acids which offer health benefits and may be used for nutraceutical purposes in the future.

Ahmad N, Hassan Y, Tangiisuran B, Meng OL, Abd Aziz N, Ahmad FU, et al.

J Eval Clin Pract, 2013 Oct;19(5):798-804.
PMID: 22583820 DOI: 10.1111/j.1365-2753.2012.01852.x

RATIONALE, AIMS AND OBJECTIVES: Existing literature suggests that doctors' poor adherence with guidelines is one of the major contributing factors to suboptimal control of hypertension. This study aims to evaluate doctors' adherence with Malaysian clinical practice guideline (CPG 2008) in a tertiary care hospital, and factors associated with guideline adherence and hypertension control.
METHODS: This was a cross-sectional study conducted at Hospital Pulau Pinang, Penang, Malaysia. Prescriptions written by 26 enrolled doctors to 650 established hypertensive outpatients (25 prescriptions per enrolled doctor) were noted on visit 1 along with patients' demographic and clinical data. The noted prescriptions were classified either as compliant or non-compliant to CPG (2008). Five hundred twenty (80%) of the enrolled patients (20 patients per enrolled doctor) were followed for one more visit. Blood pressure (BP) noted on visit 2 was related to the prescription written on visit 1. SPSS 16 (SPSS Inc., Chicago, IL, USA) was used for data analysis.
RESULTS: Three hundred forty-nine (67.1%) patients received guidelines compliant pharmacotherapy. In multivariate analysis, hypertension clinic had significant negative association with guidelines adherence. Two hundred sixty-five patients (51%) were at goal BP on visit 2. In multivariate analysis, angiotensin-converting enzyme inhibitors and guidelines adherence had significant positive, while renal disease, diabetes mellitus and diabetic clinic had significant negative association with hypertension control.
CONCLUSIONS: An overall fair level of adherence with guidelines and better control of hypertension was observed. Guidelines compliant practices resulted in better control of hypertension. The gaps between what guidelines recommend and clinical practice were especially seen in the pharmacotherapy of uncomplicated hypertension and hypertension with diabetes mellitus and renal disease.

Abd Aziz N, Chue MC, Yong CY, Hassan Y, Awaisu A, Hassan J, et al.

Int J Clin Pharm, 2011 Apr;33(2):150-4.
PMID: 21744187 DOI: 10.1007/s11096-011-9480-7

OBJECTIVE: To compare the efficacy of dexmedetomidine versus morphine as a sedative/analgesic among post-operative cardiac surgery patients.
METHOD: A randomized controlled open-label study was performed at the cardiothoracic intensive care unit of Penang Hospital, Malaysia. A total of 28 patients who underwent cardiac surgeries were randomly assigned to receive either dexmedetomidine or morphine. Both groups were similar in terms of preoperative baseline characteristics. Efficacy measures included sedation scores and pain intensity and requirements for additional sedative/analgesic. Mean heart rate and arterial blood pressure were used as safety measures. Other measures were additional inotropes, extubation time and other concurrent medications.
RESULTS: The mean dose of dexmedetomidine infused was 0.12 [SD 0.03] μg kg⁻¹ h⁻¹, while that of morphine was 13.2 [SD 5.84] μg kg⁻¹ h⁻¹. Dexmedetomidine group showed more benefits in sedation and pain levels, additional sedative/analgesic requirements, and extubation time. No significant differences between the two groups for the outcome measures, except heart rate, which was significantly lower in the dexmedetomidine group.
CONCLUSION: This preliminary study suggests that dexmedetomidine was at least comparable to morphine in terms of efficacy and safety among cardiac surgery patients. Further studies with larger samples are recommended in order to determine the significant effects of the outcome measures.
