RESUMEN
With the availability of public databases that store compound-target/compound-toxicity information, and Traditional Chinese medicine (TCM) databases, in silico approaches are used in toxicity studies of TCM herbal medicine. Here, three in silico approaches for toxicity studies were reviewed, which include machine learning, network toxicology and molecular docking. For each method, its application and implementation e.g., single classifier vs. multiple classifier, single compound vs. multiple compounds, validation vs. screening, were explored. While these methods provide data-driven toxicity prediction that is validated in vitro and/or in vivo, it is still limited to single compound analysis. In addition, these methods are limited to several types of toxicity, with hepatotoxicity being the most dominant. Future studies involving the testing of combination of compounds on the front end i.e., to generate data for in silico modeling, and back end i.e., validate findings from prediction models will advance the in silico toxicity modeling of TCM compounds.

Introduction: The spread of the novel coronavirus disease (COVID-19) may lead people to seek preventative measures. The use of herbal and dietary supplements (HDS) may have become prevalent during the COVID-19 pandemic. This study aims to identify the prevalence, predictors, and patterns of HDS use for COVID-19 prevention in a sample of the general public in a suburban town in Malaysia. Methods: An online cross-sectional survey was conducted between May and June 2021 involving adults ≥ 18 years old. Data on the self-reported use of HDS for COVID-19 prevention were collected. Logistic regression analysis was conducted to determine the predictors of HDS use. Results: Overall, 41.9 % (168/401) reported using HDS to prevent COVID-19. Multivariate analysis showed that HDS users were more likely to be individuals ≥ 40 years old (adjusted odds ratio [aOR] = 1.774, 95 % confidence interval [CI] = 1.016 - 3.098), and to have had a history of HDS use prior to the pandemic (aOR = 19.378, 95 % CI = 5.901 - 63.639). Most HDS users referred to social media or websites (66.7 %, 112/168) for HDS information. Approximately half of them had consulted either pharmacists or doctors about their HDS use. Conclusion: HDS use to prevent COVID-19 was common among the respondents. Several issues - such as the concurrent use of HDS with conventional medications, the use of unreliable sources of information, and the lack of consultation with healthcare providers (HCPs) - indicate that HCPs should be more proactive in their consultative and information-providing roles regarding HDS use.
RESUMEN
BACKGROUND: Tongkat Ali (TA) or Eurycoma longifolia is a herbal medicine (HM) plant traditionally used to treat sexual dysfunction and enhance libido in men. Websites containing information about HM are abundant. However, studies have shown that in general the quality of websites containing information on HM is low. The present study aims to assess the quality and risks of websites containing information about TA supplements and to identify the health claims for TA. METHODOLOGY: A cross-sectional study to evaluate the quality and risks of websites discussing TA supplements was conducted. Online marketing websites, research articles, news articles, personal opinions, and those restricted by password were excluded. The quality and risks of websites were assessed using a modified DISCERN tool and a set of risk assessment criteria, respectively. The health claims for TA were identified and analyzed using content analysis. RESULTS: Overall, 321 websites met the inclusion criteria and were further evaluated. The overall rating of the quality of the websites was low, with a mean score ± standard deviation of 1.07 ± 0.51. Most websites lacked information that there may be more than one possible treatment choice and did not discuss areas of uncertainty. However, 67.9% (218/321) of the websites received a risk score of zero. A minority of websites (5/321, 1.6%) discouraged the use of conventional medicines. The most common health claims for TA included in the websites related to the enhancement of testosterone level (121/321, 37.7%), treatment of malaria (112/321, 34.9%), and improvement in libido (108/321, 33.6%). CONCLUSIONS: Websites containing information about TA supplements generally have a low-quality rating based on a modified DISCERN tool despite having a low-risk score. Government agencies and healthcare professionals (HCPs) must be more proactive in the critique and dissemination of information relating to HM, and in ensuring the safe use of HM among the public and patients.

BACKGROUND AND PURPOSE: Pharmacists have been reported to have inadequate awareness about potentially inappropriate medications (PIMs) in older people. This warrants more efforts to enhance their familiarity and knowledge in this topic. A board game was developed based on the 2019 American Geriatrics Society (AGS) Beers Criteria to assist pharmacists learning the topic. EDUCATIONAL ACTIVITY AND SETTING: The board game is played using dice and pawns and involved players encounter questions on various aspects of PIMs in older people. Questions used in the board game were reviewed by a panel of experts. The board game exposed pharmacists to drug-drug and drug-disease/syndrome interactions. The board game was pilot tested among 16 pharmacists and played by a group of 34 pharmacists. Close- and open-ended feedback regarding the board game were sought in both sessions using a self-developed questionnaire. FINDINGS: All pharmacists in the pilot test (PT) and actual game (AG) sessions agreed that the board game is an innovative, useful, and interesting way to learn about PIMs in older people. All pharmacists in the PT session and a high majority of those in the AG session agreed that the board game increased their knowledge about PIMs in older people. The open-ended responses showed generally positive feedback. SUMMARY: The board game can be useful as an educational tool to supplement traditional teaching methods to assist pharmacists learning the PIMs in older people. Periodic review and relevant modifications of the board game content can be done to ensure its efficiency and relevance.

Background: A common contributory factor to falls is the use of medicines, especially those commonly known as "fall-risk increasing drugs" (FRIDs). The use of FRIDs is common among older people (OP). However, OP and their family caregivers (FCGs) are largely unaware of FRIDs and their risks in increasing the risk of falls (ROF). Methods: A booklet which aims to provide information on topics related to FRIDs was developed. The booklet was reviewed by a panel of 14 reviewers, and the content validity index (CVI) for each subsection of the booklet was computed. Pilot testing of the booklet utilized a pre-post intervention study design and included 50 OP and 50 FCGs as study participants. Perceived knowledge of the participants was assessed prior to and after completing the booklet. Participants' opinions on the usefulness and usability of the booklet were also obtained. Results: The booklet contained eight sections and each subsection of the booklet had a CVI ranging from 0.93 to 1.00. Completing the booklet resulted in improved perceived knowledge scores for each perceived knowledge item among both the OP and FCG groups (all items: p-value < 0.001). The participants perceived the booklet as useful and usable, as evidenced by almost all the perceived usefulness and usability items having a score of over 4.0. Conclusions: The FRIDs booklet developed in this study had good content validity and was widely accepted by the OP and FCGs. The positive effect on the participants' knowledge of topics related to FRIDs means that the booklet could be useful as a patient education tool to enhance FRIDs knowledge and awareness among OP and FCGs.

5-HT3R antagonists such as ondansetron, granisetron and tropisetron have been clinically used to treat nausea and vomiting in chemotherapy patients. However, current study and research revealed novel potentials of these ligands in other diseases like inflammation, Alzheimer's, and drug abuse. Towards utilising these drugs as anti-smoking agents to treat nicotine dependence problem, there are conflicting reports regarding the potential of these ligands in modulating the effects of nicotine in both human and animal behavioural studies. This is complicated by the heterogeneity of 5-HT3R itself, cross regulation between nicotinic acetylcholinergic receptor (nAChR) and distinct pharmacological profiles of 5-HT3R antagonists. This review gathered existing studies conducted investigating the potential of "-setron" class of 5-HT3R antagonists in modulating nicotine effects. We proposed that the mechanism where 5-HT3R antagonists mediate the effects of nicotine could be attributed by both direct at 5-HT3R and indirect mechanism in nicotine addiction downstream regulation. The indirect mechanism mediated by the 5-HT3R antagonist could be through α7 nAChR, 5-HT1B receptor (5-HT1BR), 5-HT1C receptor (5-HT1CR), calcineurin activity, p38 MAPK level, PPAR-γ and NF-κß. Our review suggested that future studies should focus on newer 5-HT3R antagonist with superior pharmacological profile or the one with multitarget action rather than high selectivity at single receptor.
