    Nepal experiences several medicine-use problems like any other developing country. In the recent years, there have been initiatives to introduce the concept of social pharmacy in Nepal, and there has been only a limited research in this area. The staff members at the Manipal College of Medical Sciences, Pokhara have shown keen interest in initiating several social pharmacy-related researches in the country. The members of this institute have been collaborating with two international universities, namely Universiti Sains Malaysia located in Malaysia and Chulalongkorn University located in Thailand, to get academic and technical supports. In this manuscript, the authors share their experiences in initiating social pharmacy research in the country. Authors have also mentioned the priority areas of social pharmacy research in Nepal and the importance of initiating this concept in the country.

    Background: Potentially inappropriate prescribing (PIP) is associated with the incidence of adverse drug reactions, drug-related hospitalization and other negative outcomes in older adults. After hospitalization, older adults might be discharged with several types of PIPs. Studies have found that the lack of healthcare professionals' (HCPs) knowledge regarding PIP is one of the major contributing factors in this issue. The purpose of this study is to investigate the impact of a multifaceted intervention on physicians' and clinical pharmacists' behavior regarding potentially inappropriate medication (PIM) and potential prescribing omission (PPO) among hospitalized older adults.

    Methods: This is a before-and-after study that took place in a tertiary Malaysian hospital. Discharge medications of patients ≥65 years old were reviewed to identify PIMs/PPOs using version 2 of the STOPP/START criteria. The prevalence and pattern of PIM/PPO before and after the intervention were compared. The intervention targeted the physicians and clinical pharmacists and it consisted of academic detailing and a newly developed smartphone application (app).

    Results: The study involved 240 patients before (control group) and 240 patients after the intervention. The prevalence of PIM was 22% and 27% before and after the intervention, respectively (P = 0.213). The prevalence of PPO in the intervention group was significantly lower than that in the control group (42% Vs. 53.3%); P = 0.014. This difference remained statistically significant after controlling for other variables (P = 0.015). The intervention was effective in reducing the two most common PPOs; the omission of vitamin D supplements in patients with a history of falls (P = 0.001) and the omission of angiotensin converting enzyme inhibitor in patients with coronary artery disease (P = 0.03).

    Conclusions: The smartphone app coupled with academic detailing was effective in reducing the prevalence of PPO at discharge. However, it did not significantly affect the prevalence or pattern of PIM.

    Pharmacogenomics (or pharmacogenetics), the study of the effects of genetic differences on a person’s response to drugs, can help in optimizing drug efficacy and minimizing adverse drug reactions. Interperson difference in drug metabolism is one of the important consequences of such genetic variation. This variation is determined in part by mutations in cytochrome P450 enzymes (CYPs). IMU is part of a major collaborative research project in the area of phamacogenetics and drug metabolism. Working together with USM and UiTM, our group has, since 2000, generated useful population database on genetic polymorphism of various CYP isoforms. We have successfully genotyped three major ethnic groups, Malay, Indian and Chinese for their allelic frequency of important isoforms. These include CYP2D6, CYP2C9, CYP2C8 and CYP2A6. Data generated so far collectively have contributed to our effort in mapping and constructing genomic database for Malaysian population.
    Since early 2002, our research has been focusing on developing in vitro methods in studying the functional consequences of genetic polymorphism of CYP enzymes. Using site-directed mutagenesis, CYP mutants, carrying nucleotide changes as reported in known alleles in human populations, were generated and expressed in E. coli system, and the expressed recombinant proteins were characterized using enzyme assays to determine the functional consequences of mutations. We have established a series of HPLC (high performance liquid chromatography)-based and fluorescence-based assays to investigate CYP activities. Assays that have been developed include tolbutamide methylhydroxylase, paclitaxel 6α-hydroxylase, dextromethorphan O-demethylation, testosterone 6β-hydroxylation and coumarin 7-hydroxylase assays. These assays serve as activity markers allowing comparison of catalytic activities of mutant proteins generated. Another focus of our work is to use the developed assays as a screening tool to investigate drug-herb interactions. This was achieved by co-incubation of herbal extracts and active constituents with the probe substrates in the assays followed by characterization of the kinetic behaviors of the enzymes involved using various pharmacokinetic parameters such as Km, Vmax, IC50 and Ki. This work is currently carried out with collaboration from the Institute for Medical Research (IMR) and is supported by MOSTI’s eScienceFund under RM9. It is envisaged that this screening work will give us insights on the potential of the commonly used herbs to cause pharmacokinetic interactions with other drug substrates, and allow us to elucidate the mechanisms involved in the interactions.

    Introduction: The geriatric population in Malaysia is expanding rapidly due to increased life expectancies. The vulnerability of this population to the adverse effects of medications due to multiple comorbidities and polypharmacy predisposes them to potentially inappropriate medications (PIMSs). The Beers Criteria is a recognized tool for assessing PIMs, but the level of awareness regarding these criteria among community pharmacists is currently unknown.
    This study aimed to assess the awareness and knowledge of Beers Criteria and its extent of application in practice among community pharmacists in the Klang Valley, Malaysia. Methods: A cross-sectional study was conducted among 218 community pharmacists in the Klang Valley using a validated, self-administered questionnaire. Knowledge on PIMs was assessed using a ten-question clinical vignette based on Beers Criteria. Descriptive and inferential statistics were used to analyze the data. Results: Respondents had a significant proportion of their customer base who were elderly. Only 28% of respondents were aware of Beers Criteria, and of this group only 41% were aware of the latest update. The mean score for the clinical vignette was 5.42 ± 1.98. Awareness of Beers Criteria and years of experience in practice were associated with higher knowledge scores (p < 0.05). Good geriatric practices were reported by respondents with the exception of regular usage of Beers Criteria (16.5% agreement) and regularly asking
    elderly-looking customers their age (43.6% agreement). Most respondents (74.3%) utilized other clinical resources and were confident in providing care to elderly customers. Conclusion: Awareness of Beers Criteria remains low among community pharmacists. However, pharmacists utilized other resources and demonstrated good geriatric practices. While this shows the adequacy of current practice, efforts to increase awareness of geriatric-specific tools such as Beers Criteria may address specific knowledge gaps and improve the level of care involving the elderly.

    BACKGROUND: Loss to follow-up (LTFU) is an unsuccessful treatment outcome for tuberculosis (TB) patients. In Malaysia, LTFU affects around 1 in 20 TB patients. Integration of qualitative research methods and evidence will provide a better understanding of LTFU and its underlying issues. In this study, we qualitatively explored TB patients' experiences in receiving treatment and their reasons for leaving TB care.

    METHOD: In-depth interviews of 15 patients with a history of LTFU were conducted from January to September 2020. Interview guides were developed to explore TB patients' experiences while receiving treatment, including challenges faced and reasons for treatment interruption. Data were thematically analysed using the framework method.

    RESULTS: We identified 11 emerging themes that occurred at four levels of interaction with TB patients. First, at the patient personal level, TB beliefs referring to patients' perception of illness and wellness, patients' perceived role of traditional and complementary medicine, and substance abuse were important. Second, the healthcare system and treatment factors that were highlighted included the organisation of care and treatment, interaction with healthcare professionals, particularly in communication and counselling, and TB medications' side effects. Third, structural factors including financial burden, logistical and transportation issues and work-related factors were identified to be barriers to treatment continuation. Fourth, the interpersonal level interaction of patients should not be neglected; this includes family relationships and support as well as peer influence.

    CONCLUSION: Study findings put forth issues and challenges faced by TB patients while receiving treatment and underscore areas where actions can be taken. This will contribute to informing the development and implementation of future TB control strategies that are responsive to TB patients' needs and concerns, to effectively address LTFU and ensure better treatment completion rates among TB patients in Malaysia.

    Introduction: The aim of this systematic review is to compare chemotherapeutic agents commonly used in treating recurrent urinary infection in nonpregnant women by their efficacy, tolerability, adverse effects, and cost employing network meta-analysis.

    Materials and Methods: We used three online databases, i.e., PubMed, ScienceDirect, and Cochrane Central Registry of Clinical Trials. Randomized controlled trials (RCTs) on the use of prophylactic chemotherapeutic agents used in treating nonpregnant women with recurrent urinary tract infections (RUTIs) published between 2002 and 2016 were selected. Only published papers in English were assessed for study quality, and meta-analyses were performed using fixed-effects model with NetMetaXL.

    Results: Six RCTs fulfilled the criteria. When all three variables, i.e., efficacy, adverse effects and cost were considered, nitrofurantoin 50 mg once daily for 6 months appears to rank high for prophylaxis against RUTI. When efficacy was the only factor, fosfomycin had the highest superiority compared to D-mannose, nitrofurantoin, estriol, trimethoprim-sulfamethoxazole, and cranberry juice, respectively. However, fosfomycin was also ranked highest by adverse events. When cost alone is considered, nitrofurantoin appeared the most cost-effective agent while placed third for efficacy alone.

    Conclusion: Selecting appropriate chemotherapeutic agents for RUTI will need to factor in effectiveness, adverse effects, and cost. While it is difficult to select an ideal drug, evaluation using network analysis may guide choice of medication for best practice.

    BACKGROUND: Apnoea of prematurity (AoP) is defined as a pause in breathing for 20 seconds or longer, or for less than 20 seconds when accompanied by bradycardia and hypoxaemia, in a preterm infant. An association between the severity of apnoea and neurodevelopmental delay has been reported. Continuous positive airway pressure (CPAP) is a form of non-invasive ventilatory assistance that has been shown to be relatively safe and effective in preventing and treating respiratory distress among preterm infants. It is less clear whether CPAP treatment is safe and effective in the prevention and treatment of AoP.

    OBJECTIVES: 1. To assess the effects of CPAP on AoP in preterm infants (this may be compared to supportive care or mechanical ventilation). 2. To assess the effects of different CPAP delivery systems on AoP in preterm infants.

    SEARCH METHODS: Searches were conducted in September 2022 in the following databases: Cochrane Library, MEDLINE, Embase, and CINAHL. We also searched clinical trial registries and the reference lists of studies selected for inclusion.

    SELECTION CRITERIA: We included all randomised and quasi-randomised controlled trials (RCTs) in which researchers determined that CPAP was necessary for AoP in preterm infants (born before 37 weeks). Cross-over studies were also included, provided sufficient data were available for analysis.

    DATA COLLECTION AND ANALYSIS: We used the standard methods of Cochrane and Cochrane Neonatal, including independent assessment of risk of bias and extraction of data by at least two review authors. Discrepancies were resolved by involvement of a third author. We used the GRADE approach to assess the certainty of evidence for the following outcomes: 1) failed CPAP; 2) apnoea; 3) adverse effects of CPAP.

    MAIN RESULTS: We included four single-centre trials conducted in Malaysia, Spain, Germany, and North America, involving 138 infants with a mean/median gestation of 26 to 28 weeks. Two studies were parallel-group RCTs and two were cross-over trials. None of the studies compared CPAP with supportive care. All trials compared one form of CPAP with another. Two compared a variable flow device with ventilator CPAP, one compared two different variable flow devices, and one compared a variable flow device with bubble CPAP. Interventions were administered for periods ranging between six and 48 hours, with pressures between 4 and 6 cm H2O. We assessed all trials as having a high risk of bias for blinding of participants and personnel, and two studies for blinding of outcome assessors. We found a high risk of a carry-over effect in two studies where the washout period was not adequately described, and a high risk of bias in a study that appeared to use an analysis method not generally accepted for cross-over studies. Comparison 1. CPAP and supportive care compared to supportive care alone We did not identify any study for inclusion in this comparison. Comparison 2. CPAP delivered by different types of devices 2a. Variable flow compared to ventilator CPAP Two studies were included in this comparison. We are very uncertain whether there is any difference in the incidence of failed CPAP, defined as the need for mechanical ventilation (risk ratio (RR) 0.16, 95% confidence interval (CI) 0.01 to 2.90; 1 study, 26 participants; very low-certainty). We are very uncertain whether there is any difference in the frequency of apnoea events (mean difference (MD) per four-hour interval -0.10, 95% CI -1.30 to 1.10; 1 study, 26 participants; very low-certainty). We are uncertain whether there is any difference in adverse events. Neurodevelopmental outcomes were not reported. 2b. Variable flow compared to bubble CPAP We included one study in this comparison, but it did not report our pre-specified outcomes. 2c. Infant Flow variable flow CPAP compared to Medijet variable flow CPAP We are very uncertain whether there is any difference in the incidence of failed CPAP (RR 2.62, 95% CI 0.91 to 7.53; 1 study, 80 participants; very low-certainty). The frequency of apnoea was not reported, and we do not know whether there is any difference in adverse events. Neurodevelopmental outcomes were not reported. Comparison 3. CPAP compared to mechanical ventilation We did not identify any studies for inclusion in this comparison.

    AUTHORS' CONCLUSIONS: Due to the limited available evidence, we are very uncertain whether any CPAP device is more effective than other forms of supportive care, other CPAP devices, or mechanical ventilation for the prevention and treatment of AoP. The devices used in these studies included two types of variable flow CPAP device: bubble CPAP and ventilator CPAP. For each comparison, data were only available from a single study. There are theoretical reasons why these devices might have different effects on AoP, therefore further trials are indicated.

    PURPOSE: Regulatory discrepancies may exist in pharmacovigilance (PV) structure, process, and outcome status worldwide. Our study's objective was to survey the current status of PV in each regulatory body in the Asia-Pacific Economic Cooperation (APEC) region.

    METHODS: A modified questionnaire was sent to the PV team heads of 21 PV agencies based in the APEC countries, between June 28 and September 12, 2017, to gather information on the structure, process, and outcome of PV status in these countries.

    RESULTS: Of the 21 APEC countries, 15 responded. We found harmonized laws and regulations for general PV and risk management systems. However, variations were found in PV structure: for example, 11 out of 15 countries had national regulatory representatives responsible for PV in pharmaceutical companies, while four did not. For PV process, discrepancies were also found in the source type of adverse drug reaction (ADR) reports and reporting of medication errors and therapeutic ineffectiveness in cumulative ADR reports. With respect to PV outcomes, among countries that performed active surveillance, the United States of America was more active, with hundreds of projects including additional pharmacoepidemiological studies etc. Among the nine countries that responded, Japan had the greatest number of product label changes followed by Taiwan, Malaysia, and Korea.

    CONCLUSION: We have identified substantial variations in the structures, processes, and outcomes of PV status among the countries of the APEC region. Therefore, efforts to reduce variations in the PV administration and regulation are warranted for harmonization of PV within the APEC region.

    BACKGROUND: While efavirenz-associated adverse drug events (ADEs) were widely established, the clinical relevance is uncertain.

    OBJECTIVES: We aimed to assess the extent of treatment interruption caused by efavirenz-associated ADEs.

    METHODS: A case-control study of efavirenz recipients who did, versus did not (control) develop adverse drug events (ADE), and who were matched for baseline CD4 + at a ratio of 1:1.3 was conducted. Antiretroviral -naïve patients who were started on efavirenz were followed up retrospectively, and their records scrutinized every month for 2 years. Demographic and clinical predictors of treatment interruption were computed using Cox proportional hazard models. Kaplan- Meier curves were plotted to assess time to treatment interruption for the two groups. Clinical endpoints were: i) efficacy -improved CD4 + counts and/or viral load (VL) suppression, ii) safety -absence of treatment-limiting toxicities, and iii) durability - no interruption until follow-up ended.

    RESULTS: Both groups had comparable CD4 + counts at baseline (p = 0.15). At t = 24-months, VL in both groups were suppressed to undetectable levels (<20 copies/mL) while median CD4 + was 353 cells/µL (IQR: 249-460). The mean time on treatment was 23 months (95% CI, 22.3 -23.4) in the control group without ADE and 20 months (95% CI, 18.9 - 21.6) in the ADE group (p = 0.001). Kaplan-Meier plots demonstrated that 59.5% of patients who experienced ≥ 1 ADE versus 81% of those who did not experience any ADE were estimated to continue treatment for up to 24 months with no interruption (p = 0.001). Most interruptions to EFV treatment occurred in the presence of opportunistic infections and these were detected within the first 5 months of treatment initiation. Independent predictors which negatively impacted the dependent variable i.e., treatment durability, were intravenous drug use (adjusted hazard ratio, aHR 2.17, 95% CI, 1.03-4.61, p = 0.043), presence of ≥ 1 opportunistic infection(s) (aHR 2.2, 95% CI, 1.13-4.21, p = 0.021), and presence of ≥ 1 serious ADE(s) (aHR 4.18, 95% CI, 1.98-8.85, p = 0.00).

    CONCLUSION: Efavirenz' role as the preferred first-line regimen for South-East Asia's resource-limited regions will need to be carefully tailored to suit the regional population. Findings have implications to policy-makers and clinicians, particularly for the treatment of patients who develop ADEs and opportunistic infections, and for intravenous drug user subgroups.

    Tuberculosis (TB) and human immunodeficiency virus (HIV) infection interfere and impact the pathogenesis phenomena of each other. Owing to atypical clinical presentations and diagnostic complications, HIV/TB co-infection continues to be a menace for healthcare providers. Although the increased access to highly active antiretroviral therapy (HAART) has led to a reduction in HIV-associated opportunistic infections and mortality, the concurrent management of HIV/TB co-infection remains a challenge owing to adverse effects, complex drug interactions, overlapping toxicities and tuberculosis -associated immune reconstitution inflammatory syndrome. Several hypotheses have been put forward for the exacerbation of tuberculosis by HIV and vice versa supported by immunological studies. Discussion on the mechanisms produced by infectious cofactors with impact on disease pathology could shed light on how to design potential interventions that could decelerate disease progression. With no vaccine for HIV and lack of an effective vaccine for tuberculosis, it is essential to design strategies against HIV-TB co-infection.

    Identifying effective drug targets, with little or no side effects, remains an ever challenging task. A potential pitfall of failing to uncover the correct drug targets, due to side effect of pleiotropic genes, might lead the potential drugs to be illicit and withdrawn. Simplifying disease complexity, for the investigation of the mechanistic aspects and identification of effective drug targets, have been done through several approaches of protein interactome analysis. Of these, centrality measures have always gained importance in identifying candidate drug targets. Here, we put forward an integrated method of analysing a complex network of cancer and depict the importance of k-core, functional connectivity and centrality (KFC) for identifying effective drug targets. Essentially, we have extracted the proteins involved in the pathways leading to cancer from the pathway databases which enlist real experimental datasets. The interactions between these proteins were mapped to build an interactome. Integrative analyses of the interactome enabled us to unearth plausible reasons for drugs being rendered withdrawn, thereby giving future scope to pharmaceutical industries to potentially avoid them (e.g. ESR1, HDAC2, F2, PLG, PPARA, RXRA, etc). Based upon our KFC criteria, we have shortlisted ten proteins (GRB2, FYN, PIK3R1, CBL, JAK2, LCK, LYN, SYK, JAK1 and SOCS3) as effective candidates for drug development.

    BACKGROUND: The response to the vaccine may vary among individuals. Hence, it is important to know how often individuals experience side effects after immunization against COVID-19.

    OBJECTIVE: This study aimed to assess the incidence of side effects following COVID-19 vaccination across different vaccine recipients in Southern Pakistan and identify the potential factors associated with these side effects in the population.

    METHODS: The survey was conducted across Pakistan through Google-forms Links from August to October 2021. The questionnaire included demographic information and COVID-19 vaccine information. Chi-square (x2) was performed for comparative analysis to check the significance level with P <0.05. The final analysis included 507 participants who had received COVID-19 vaccines.

    RESULTS: Of the total 507 COVID-19 vaccines recipients, 24.9% received CoronaVac, 36.5% received BBIBP-CorV, 14.2% received BNT162b2, 13.8% received AZD1222, and 10.7% received mRNA-1273. The most prominent side effects after the first dose were fever, weakness, lethargy, and pain at the site of injection. Moreover, the most commonly reported side effects after the second dose were pain at the injection site, headache, body ache, lethargy, fever, chills, flu-like symptoms, and diarrhea.

    CONCLUSION: Our results suggested that the side effects due to COVID-19 vaccination can vary between the first and second doses and type of COVID-19 vaccine. Our findings suggest continuing monitoring of vaccine safety and the importance of individualized risk-benefit assessment for COVID-19 immunization.

    Adverse drug reactions (ADRs) are considered as one of the leading causes of death among hospitalized patients. Thus reporting of adverse drug reactions become an important phenomenon. Spontaneous adverse drug reaction reporting form is an essential component and a major tool of the pharmacovigilance system of any country. This form is a tool to collect information of ADRs which helps in establishing the causal relationship between the suspected drug and the reaction. As different countries have different forms, our aim was to study, analyze the suspected adverse drug reaction reporting form of different countries, and assess if these forms can capture all the data regarding the adverse drug reaction. For this analysis we identified 18 points which are essential to make a good adverse drug reaction report, enabling proper causality assessment of adverse reaction to generate a safety signal. Adverse drug reaction reporting forms of 10 different countries were collected from the internet and compared for 18 points like patient information, information about dechallenge-rechallenge, adequacy of space and columns to capture necessary information required for its causality assessment, etc. Of the ADR forms that we analyzed, Malaysia was the highest scorer with 16 out of 18 points. This study reveals that there is a need to harmonize the ADR reporting forms of all the countries because there is a lot of discrepancy in data captured by the existing ADR reporting forms as the design of these forms is different for different countries. These incomplete data obtained result in inappropriate causality assessment.

    PURPOSE: This study aimed to explore the current landscape and identify challenges of pharmacovigilance (PV) among Association of Southeast Asian Nations (ASEAN) countries.

    METHODS: This cross-sectional survey collected data from May 2014 to December 2015. Questionnaires seeking to collect information on resources, processes, roles and responsibility, and functions of PV systems were sent to relevant persons in the ASEAN countries. Functions of PV centers were measured using the minimum World Health Organization requirements for a functional national PV system. Performances of PV centers were measured by the following: (1) the indicators related to the average number of individual case safety reports (ICSR); (2) presence of signal detection activities and subsequent action; and (3) contribution to the global vigilance database.

    RESULTS: Cambodia, Indonesia, Laos, Malaysia, the Philippines, Singapore, Thailand, and Vietnam completed the survey. PV systems in four surveyed countries (Indonesia, Malaysia, Singapore, and Thailand) achieved all aspects of the World Health Organization minimum requirement for a functional national PV system; the remaining countries were deemed to have unclear communication strategies and/or no official advisory committee. Average numbers of recent ICSR national returns ranged from 7 to 3817 reports/year/million population; three countries (Malaysia, Singapore, and Thailand) demonstrated good performance in reporting system and reported signal detection activities and subsequent actions. All participating countries had submitted ICSRs to the Uppsala Monitoring Center during the survey period (2013-2015).

    CONCLUSIONS: Four participating countries had functional PV systems. PV capacity, functionality, and legislative framework varied depending on local healthcare ecosystem networks. Implementing effective communication strategies and/or technical assistance from the advisory committee are needed to strengthen PV in ASEAN. Copyright © 2016 John Wiley & Sons, Ltd.
