    Adherence to medications is an important factor that contributes to therapeutic success. With the current increase in the elderly population, information relating to adherence to treatment and quality of life (QoL) of diabetic elderly patients will help the healthcare provider to improve their treatment. Thus, this study aims to determine the factors affecting adherence to medications and the consequence of non adherence to QoL.

    Alzheimer's disease (AD) is a neurodegenerative disease characterized by impaired memory function and oxidative damage. NO is a major signaling molecule produced in the central nervous system to modulate neurological activity through modulating nitric oxide synthase. Recently, PPAR-γ agonists have shown neuroprotective effects in neurodegenerative disorders. However, there have been only a few studies identifying mechanisms through which cognitive benefits may be exerted. The present study was designed to investigate the possible nitric oxide mechanism in the protective effect of pioglitazone against streptozotocin (STZ)-induced memory dysfunction. Wistar rats were intracerebroventricularly (ICV) injected with STZ. Then rats were treated with pioglitazone, NO modulators [L-arginine and nitro-L-arginine methyl ester (L-NAME)] for 21 days. Behavioral alterations were assessed in between the study period. Animals were sacrificed immediately after behavioral session, and mito-oxidative parameters, TNF-α, IL-6, and caspase-3 activity were measured. STZ-treated rats showed a memory deficit and significantly increased in mito-oxidative damage and inflammatory mediators and apoptosis in the hippocampus. Chronic treatment of pioglitazone significantly improved memory retention and attenuated mito-oxidative damage parameters, inflammatory markers, and apoptosis in STZ-treated rats. However, L-arginine pretreatment with lower dose of pioglitazone has not produced any protective effect as compared to per se. Furthermore, pretreatment of L-NAME significantly potentiated its protective effect, which indicates the involvement of nitric oxide for activation of PPAR-γ action. These results demonstrate that pioglitazone offers protection against STZ-induced memory dysfunction possibly due to its antioxidant, anti-inflammatory, and anti-apoptotic action mediating nitric oxide pathways and, therefore, could have a therapeutic potential in AD.

    Reflexology is basically a study of how one part of the human body relates to another part of the body. Reflexology practitioners rely on the reflexes map of the feet and hands to all the internal organs and other human body parts. They believe that by applying the appropriate pressure and massage certain spots on the feet and hands, all other body parts could be energized and rejuvenated. This review aimed to revisit the concept of reflexology and examine its effectiveness, practices, and the training for reflexology practitioners. PubMed, SCOPUS, Google Scholar, and SpringerLink databases were utilized to search the following medical subject headings or keywords: foot massage, reflexology, foot reflexotherapy, reflexological treatment, and zone therapy. The articles published for the last 10 years were included. Previous systematic reviews failed to show concrete evidence for any specific effect of reflexology in any conditions. Due to its non-invasive, non-pharmacological complementary nature, reflexology is widely accepted and anecdotal evidence of positive effect reflexology in a variety of health conditions are available. Adequate training for practitioners is necessary to ensure the consistency of service provided.

    Background: This study utilized a validated combination of a COPD Population Screener
    (COPD-PS) questionnaire and a handheld spirometric device as a screening tool for patients at high risk of COPD, such as smokers. The study aimed to investigate and pilot the feasibility and application of this combined assessment, which we termed the “VitalQPlus”, as a screening tool for the early detection of COPD, especially in primary care settings.
    Methods: This was a cross-sectional study screening potentially undiagnosed COPD patients using a validated five-item COPD-PS questionnaire together with a handheld spirometric device. Patients were recruited from selected Malaysian government primary care health centers.
    Results: Of the total of 83 final participants, only 24.1% (20/83) were recruited from Perak and Penang (peninsular Malaysia) compared to 75.9% (63/83) from Sabah (Borneo region). Our dual assessment approach identified 8.4% of the surveyed patients as having potentially undiagnosed COPD. When only the Vitalograph COPD-6 screening tool was used, 15.8% of patients were detected with a forced expiratory volume in 1 second/forced expiratory volume in 6 seconds (FEV1/FEV6) ratio at <0.75, while 35.9% of patients were detected with the COPD-PS questionnaire. These findings suggested that this dual assessment approach has a greater chance of identifying potentially undiagnosed COPD patients compared to the Vitalograph COPD-6 or COPD-PS questionnaire when used alone. Our findings show that patients with more symptoms (scores of >=5) yielded twice the percentage of outcomes of FEV1/FEV6 <0.75 compared to patients with fewer COPD symptoms (scores <5).
    Conclusion: With the availability of a simple screening questionnaire and the COPD-6, there is an opportunity easily to make patients more aware of their lung symptoms and to encourage the provision of early treatment. The proposed dual assessment approach, which we termed the VitalQPlus, may play a profound role in the early diagnosis of COPD, which is crucial in improving the clinical management of the disease.

    BACKGROUND: Medication error (ME) is a worldwide issue, but most studies on ME have been undertaken in developed countries and very little is known about ME in Southeast Asian countries. This study aimed systematically to identify and review research done on ME in Southeast Asian countries in order to identify common types of ME and estimate its prevalence in this region.

    METHODS: The literature relating to MEs in Southeast Asian countries was systematically reviewed in December 2014 by using; Embase, Medline, Pubmed, ProQuest Central and the CINAHL. Inclusion criteria were studies (in any languages) that investigated the incidence and the contributing factors of ME in patients of all ages.

    RESULTS: The 17 included studies reported data from six of the eleven Southeast Asian countries: five studies in Singapore, four in Malaysia, three in Thailand, three in Vietnam, one in the Philippines and one in Indonesia. There was no data on MEs in Brunei, Laos, Cambodia, Myanmar and Timor. Of the seventeen included studies, eleven measured administration errors, four focused on prescribing errors, three were done on preparation errors, three on dispensing errors and two on transcribing errors. There was only one study of reconciliation error. Three studies were interventional.

    DISCUSSION: The most frequently reported types of administration error were incorrect time, omission error and incorrect dose. Staff shortages, and hence heavy workload for nurses, doctor/nurse distraction, and misinterpretation of the prescription/medication chart, were identified as contributing factors of ME. There is a serious lack of studies on this topic in this region which needs to be addressed if the issue of ME is to be fully understood and addressed.

    BACKGROUND: Breast cancer is the most common cancer and the leading cause of cancer mortality among women of all ethnic and age groups in Malaysia. Delay in seeking help for breast cancer symptoms is preventable and by identifying possible factors for delayed diagnosis, patient prognosis and survival rates could be improved.

    OBJECTIVES: This narrative review aimed to understand and evaluate the level of in-depth breast cancer knowledge in terms of clinical breast examination and breast self-examination, and other important aspects such as side-effects and risk factors in Malaysian females. Since Malaysia is multicultural, this review assessed social perceptions, cultural beliefs and help-seeking behaviour in respect to breast cancer among different ethnic groups, since these may impinge on efforts to 'avoid' the disease.

    MATERIALS AND METHODS: A comprehensive literature search of seven databases was performed from December 2015 to January 2015. Screening of relevant published journals was also undertaken to identify available information related to the knowledge, perception and help-seeking behaviour of Malaysian women in relation to breast cancer.

    RESULTS: A total of 42 articles were appraised and included in this review. Generally, women in Malaysia had good awareness of breast cancer and its screening tools, particularly breast self-examination, but only superficial in-depth knowledge about the disease. Women in rural areas had lower levels of knowledge than those in urban areas. It was also shown that books, magazines, brochures and television were among the most common sources of breast cancer information. Delay in presentation was attributed mainly to a negative social perception of the disease, poverty, cultural and religion practices, and a strong influence of complementary and alternative medicine, rather than a lack of knowledge.

    CONCLUSIONS: This review highlighted the need for an intensive and in-depth breast cancer education campaigns using media and community health programmes, even with the existing good awareness of breast cancer. This is essential in order to avoid misconceptions and to frame the correct mind-set about breast cancer among women in Malaysia. Socio-cultural differences and religious practices should be taken into account by health care professionals when advising on breast cancer. Women need to be aware of the risk factors and symptoms of breast cancer so that early diagnosis can take place and the chances of survival improved.

    BACKGROUND: The treatment of low back pain is very challenging due to the recurrent nature of the problem. It is believed that traditional Malay massage helps to relieve such back pain but there is a lack of scientific evidence to support both the practice of traditional Malay massage and the mechanism by which it exerts its effect. The aim of this study is to investigate the immediate effect of traditional Malay massage on the pain scale, substance P, inflammatory mediators, and functional outcomes among low back pain patients.

    METHODS: A non-blinded, randomised controlled trial will be conducted. A total of sixty-six patients who fulfil the inclusion criteria will be recruited. The participants will be randomly allocated into intervention (traditional Malay massage) and control (relaxation position) groups. Blood and saliva samples will be collected before and immediately after intervention. All collected samples will be analysed. The primary outcomes are the changes in the level of substance P in both saliva and blood samples between both groups. The secondary outcomes include the levels of inflammatory mediators [i.e. TNF-α, IL-1β, IL-8, monocyte chemotactic protein-1, IL-6 and IL-10, and the soluble form of the intercellular adhesion molecule], the pain intensity as measured by a visual analogous scale and functional outcomes using the Roland-Morris Disability Questionnaire.

    DISCUSSION: Massage is a type of physical therapy that has been proven to be potentially capable of reducing unpleasant pain sensations by a complex sensory response and chemical mediators such as substance P and various inflammatory mediators. Previous studies conducted using Thai, Swedish, or other forms of massage therapies, have showed inconsistent findings on substance P levels pre and post the interventions. Each massage genre varies in terms of massage and joint mobilization points, as well as the lumbar spinous process. Traditional Malay massage, known locally as "Urut Melayu", involves soft-tissue manipulation of the whole body applied using the hands and fingers. This massage technique combines both deep muscular tissue massage and spiritual rituals. This trial is expected to give rise to new knowledge underlying the mechanisms for pain and inflammation relief that are activated by traditional Malay massage.

    BACKGROUND: Handheld computers (HHCs) such as smartphones and tablets are providing a variety of drug information (DI) applications to assist pharmacists' decision making in the clinical and hospital setting. However, little is known about the extent of their use among Malaysian pharmacists. The current study aimed to assess the use of electronic DI resources via HHCs by pharmacists in Malaysia. This study also aimed to investigate the pharmacists' perception toward the DI content and functions of mobile medical applications.

    METHODS: A convenience sampling method was adopted to invite pharmacists (N = 450) working in various sectors such as hospitals, the drug approval authority, and academia to participate in this online survey. A 36-item questionnaire was administered, and data were summarized and presented using descriptive statistics.

    RESULTS: The response rate to this survey was 49.8% (n = 224). Overall, 213 respondents (95.1%) were active HHCs users in their daily clinical practice. About 194 respondents (86.6%) disclosed that they often use HHCs for searching DI. Dosage recommendations (n = 198; 88.4%), adverse drug reactions (n = 153; 68.3%), and drug interactions (n = 146; 65.2%) were the most common DI retrieved. Meanwhile, general dosage recommendation, pediatric dosage recommendations and dosage recommendations for renal failure were ranked as the most important DI in mobile medical applications. Gaining access to the latest information on drugs and clinical practice were regarded as the most important functions of the mobile medical app.

    CONCLUSIONS: The use of HHCs for DI among pharmacists in Malaysia was high. The use of locally produced DI sources is still low compared to overseas sources. The most popular applications used for drug-related medical information were Micromedex, followed by Lexicomp and Medscape.

    Organophosphate pesticides are used in agriculture where they are associated with numerous cases of intentional and accidental misuse. These toxicants are potent inhibitors of cholinesterases leading to a massive build-up of acetylcholine which induces an array of deleterious effects, including convulsions, oxidative damage and neurobehavioral deficits. Antidotal therapies with atropine and oxime yield a remarkable survival rate, but fail to prevent neuronal damage and behavioral problems. It has been indicated that multifunction drug therapy with potassium channel openers, calcium channel antagonists and antioxidants (either single-agent therapy or combination therapy) may have the potential to prevent cell death and/or slow down the processes of secondary neuronal damage. The aim of the present study, therefore, was to make a relative assessment of the potential effects of nicorandil (2 mg/kg), clinidipine (10 mg/kg), and grape seed proanthocyanidin (GSPE) extract (200 mg/kg) individually against subacute chlorpyrifos induced toxicity. The test drugs were administered to Wistar rats 2 h after exposure to Chlorpyrifos (CPF). Different behavioral studies and biochemical estimation has been carried in the study. The results showed that chronic administration of CPF significantly impaired learning and memory, along with motor coordination, and produced a marked increase in oxidative stress along with significantly reduced acetylcholine esterase (AChE) activity. Treatment with nicorandil, clinidipine and GSPE was shown to significantly improve memory performance, attenuate oxidative damage and enhance AChE activity in rats. The present study also suggests that a combination of nicorandil, clinidipine, and GSPE has a better neuroprotective effect against subacute CPF induced neurotoxicity than if applied individually. © 2015 Wiley Periodicals, Inc.

    OBJECTIVES: To assess community pharmacists'/pharmacy technicians' knowledge and perceptions about adverse drug reactions (ADRs) and barriers towards the reporting of such reactions in Dhaka, Bangladesh.

    METHOD: A cross-sectional study was planned to approach potential respondents for the study. A self-administered questionnaire was delivered to community pharmacists/pharmacy technicians (N=292) practising in Dhaka, Bangladesh.

    RESULTS: The overall response to the survey was 69.5% (n=203). The majority of the sample was comprised of pharmacy technicians (152, 74.9%) who possessed a diploma in pharmacy, followed by pharmacists (37, 18.2%) and others (12, 5.9%). Overall, 72 (35.5%) of the respondents disclosed that they had experienced an ADR at their pharmacy, yet more than half (105, 51.7%) were not familiar with the existence of an ADR reporting body in Bangladesh. Exploring the barriers to the reporting of ADRs, it was revealed that the top four barriers to ADR reporting were 'I do not know how to report (Relative Importance Index (RII)=0.998)', 'reporting forms are not available (0.996)', 'I am not motivated to report (0.997)' and 'Unavailability of professional environment to discuss about ADR (RII=0.939)'. In addition to these, a majority (141, 69.46%) were not confident about the classification of ADRs (RII=0.889) and were afraid of legal liabilities associated with reporting ADRs (RII=0.806). Moreover, a lack of knowledge about pharmacotherapy and the detection of ADRs was another major factor hindering their reporting (RII=0.731).

    CONCLUSIONS: The Directorate of Drug Administration in Bangladesh needs to consider the results of this study to help it improve and simplify ADR reporting in Bangladeshi community pharmacy settings.

    OBJECTIVES: To examine the appropriateness of antibiotics prescribed for acute infection based on the Malaysian national antibiotic guidelines and the defined daily dose (DDD) system of the World Health Organization (WHO). This study also aimed to describe the factors influencing the drug use pattern and to investigate the procurement patterns of antibiotics in the primary healthcare setting.
    METHODS: A retrospective cohort follow-up study of randomly selected patients from all patients who received any antibiotic between January and December 2013 was conducted at three primary healthcare clinics in Selangor State of Malaysia. For each patient, the following information was recorded: name of the antibiotic, frequency and dose, and Anatomical Therapeutic Chemical (ATC) group. The defined daily dose per 1000 inhabitants per day was calculated for each antibiotic. The national antibiotic guidelines were used to assess the appropriateness of each antibiotic prescription.
    RESULTS: A total of 735 patients were included in the study. The five most used antibiotics were amoxicillin (1.36g, 35.2%), cloxacillin (0.68g, 26.3%), erythromycin (0.32g, 22.3%), bacampicillin (0.13g, 7.2%), and cephalexin (0.11g, 6.9%). Respiratory tract infections were the most commonly treated infections, and the doctors' preferred antibiotic for the treatment of these infections was amoxicillin. More than 18% of all amoxicillin prescriptions were deemed inappropriate according to the national antibiotic guidelines. In terms of procurement costs, USD 88885 was spent in 2011, USD 219402 in 2012, and USD 233034 in 2013 at the three primary healthcare clinics, an average of USD 180440 per year for the three clinics.
    CONCLUSIONS: This study reports the antibiotic usage at three primary healthcare clinics in Klang Province. The most prescribed antibiotic was amoxicillin in capsules (250mg), which was mainly prescribed for respiratory infections. Although the national antibiotic guidelines state that amoxicillin is a preferred drug for acute bacterial rhinosinusitis, this drug is also being prescribed for other disease conditions, such as acute pharyngitis and acute tonsillitis. This result shows that current practice is not following the current antibiotic guidelines, which state that phenoxypenicillin should be the preferred drug.

    BACKGROUND: Fluoroquinolones are the backbone of multidrug resistant tuberculosis treatment regimens. Despite the high burden of multidrug resistant tuberculosis in the country, little is known about drug resistance patterns, prevalence, and predictors of fluoroquinolones resistance among multidrug resistant tuberculosis patients from Pakistan.
    OBJECTIVE: To evaluate drug resistance patterns, prevalence, and predictors of fluoroquinolones resistance in multidrug resistant tuberculosis patients.
    METHODS: This was a cross-sectional study conducted at a programmatic management unit of drug resistant tuberculosis, Lady Reading Hospital Peshawar, Pakistan. Two hundred and forty-three newly diagnosed multidrug resistant tuberculosis patients consecutively enrolled for treatment at study site from January 1, 2012 to July 28, 2013 were included in the study. A standardized data collection form was used to collect patients' socio-demographic, microbiological, and clinical data. SPSS 16 was used for data analysis.
    RESULTS: High degree of drug resistance (median 5 drugs, range 2-8) was observed. High proportion of patients was resistant to all five first-line anti-tuberculosis drugs (62.6%), and more than half were resistant to second line drugs (55.1%). The majority of the patients were ofloxacin resistant (52.7%). Upon multivariate analysis previous tuberculosis treatment at private (OR=1.953, p=0.034) and public private mix (OR=2.824, p=0.046) sectors were predictors of ofloxacin resistance.
    CONCLUSION: The high degree of drug resistance observed, particularly to fluoroquinolones, is alarming. We recommend the adoption of more restrictive policies to control non-prescription sale of fluoroquinolones, its rational use by physicians, and training doctors in both private and public-private mix sectors to prevent further increase in fluoroquinolones resistant Mycobacterium tuberculosis strains.

    This study aimed to investigate the effects of parenteral nutrition (PN) administration of amino acids (AA) on physical changes among very low birth weight infants in a local hospital setting in Malaysia. A retrospective study was carried out at a hospital in Malaysia. Records of neonates prescribed PN in the neonatal unit in 2012 were screened for eligibility. A total of 199 premature neonates received PN support in the year 2012 and, of these, 100 fulfilled the inclusion criteria. The median value of AA intake on the first day of PN was 2.00 (<28 weeks group); 1.00 (28-31 weeks group) and 0.75 (>31 weeks group). Neonates in the <28 weeks group were more likely to receive AA at an earlier time and higher initial dose compared with the other age groups. The study also found that there was no statistically significant difference in the dose of AA on the first day of PN administration and that the significant variations in nutritional parameters among the subjects did not lead to differences in physical outcomes. This study identified that when PN is provided in the local hospital setting, it is likely that the current nutritional practices are inadequate to achieve the standard growth recommendations. Our findings call for a need to optimize AA and calorie intake since growth restriction is a morbidity which will affect the infants' growth and development. Current prescriptions for PN in this hospital need to be reviewed in order to improve patient outcomes.
