Abstract
Electret technology was widely used to prevent the airborne transmission of bioaerosols during the COVID-19 pandemic and improve the filtration efficiency of masks and high-efficiency particulate air (HEPA) filters. As alcohol disinfectants are widely used in medical and welfare institutions, concerns about alcohol exposure inactivating electret exist. However, comprehensive alcohol exposure tests have not been conducted on masks and HEPA filters distributed in Japan. Twenty-five types of masks and five types of HEPA filters were subjected to a discharging process according to ISO 16890 to quantitatively elucidate the resistance to alcohol exposure. Measurements of changes in filtration efficiency and pressure drop before and after discharge show that 17 masks (68%) and four HEPA filters (80%) exhibited a significant decrease in filtration efficiency, confirming their vulnerability to alcohol. In addition, a survey (n = 500 Japanese adults, including 30 healthcare professionals) revealed that ∼90% of the general public were unaware that alcohol exposure could degrade masks and air purifiers. Furthermore, 36% of the surveyed healthcare professionals had sprayed alcohol directly onto their masks. The effectiveness of user warnings through product labels and instructions was investigated from the perspective of ensuring the safety of patients and healthcare professionals. Results revealed that the best approach was to describe the extent and duration of the adverse effects caused by disregarding precautions. Increase in awareness of healthcare professionals and general public by authorities and manufacturers through guidelines and warning labels would reduce the risk of inhaling bioaerosols caused by unintentional electret inactivation.

Abstract
Introduction: The unmet need for highly effective, naturally derived products with minimal side effects results in the over-popularity of ever-newer medicinal plants. In the middle of 2010, products containing cannabidiol (CBD), one of the special metabolites of Cannabis sativa, started to gain popularity. For consumers and healthcare providers alike, the legal context surrounding the marketing of CBD products is not entirely clear, and the safety of using some products is in doubt. Companies in the online medicinal product market profit from the confusion around CBD oils. Methods: In our study, we employed a complex method known as risk-based safety mapping of the online pharmaceutical market, which included health claim content analysis of online stores, test purchases, and labeling and quantitative analysis of the CBD content. Results: There were discovered 16 online retailers selling an average of 2-7 goods and CBD oils with a concentration of 3%-5% (30-50 mg/mL) CBD. The majority (n/N = 10/16, 62.5%) displayed potential health-related benefits indirectly on their website, and in the case of one web shop (n/N = 1/16, 6.3%), we detected COVID-19-related use. Altogether, 30 types of purported "indications" were collected. A total of 12 CBD oil products were test-purchased from online retailers in December 2020. Upon evaluating the packaging and product information, we noticed that three products (n/N = 3/12, 25%) lacked instructions on use, hence increasing the risk of inappropriate application and dosing. The cannabidiol content was quantified using UHPLC. The measured CBD concentrations of the products ranged from 19.58 mg/mL to 54.09 mg/mL (mean 35.51 mg/mL, median 30.63 mg/mL, and SD ± 12.57 mg/mL). One (8.33%) product was underlabeled, five (41.67%) were over-labeled, and only every second product (50%) was appropriately labeled based on the quantitative assessment of CBD concentration. Discussion: Further research and quality control are necessary to establish the regulatory context of the usage and classification of CBD and other cannabinoids in nonmedicinal products (e.g., food supplements), as authorities and policymakers worldwide struggle with the uncertainties surrounding CBD products.

Abstract
To determine the socioeconomic and demographic factors associated with the influence of the nutritional traffic light (NTL) on the decision to purchase processed foods using information from the National Health and Nutrition Survey (ENSANUT) 2018 of Ecuador, a cross-sectional and analytical study based on a secondary analysis of the information from the ENSANUT 2018 was performed. We collected data from 25,932 participants 18 years of age or older who knew or had seen the NTL, and for whom complete information on the variables of interest for the study was available. The "Influence of the NTL on the purchase decision of processed foods" was the outcome variable of the study. Generalized linear models of the Poisson family, with log link, were used to assess the association between socioeconomic factors and outcome, using crude (PR) and adjusted (aPR) prevalence ratios, with 95% confidence intervals (CI) and a p-value < 0.05. Participants who understood the NTL (aPR: 2.49; 95% CI: 2.19-2.83), with a higher educational level (aPR: 1.33; 95% CI: 1.09-1.61), women (aPR 1.06; 95% CI: 1.01-1.10), and who had a partner (aPR 1.09; 95% CI: 1.04-1.14) were more likely to be influenced by the NTL when deciding to purchase processed foods, compared to people who did not understand the NTL, who had no educational level or who only attended a literacy center, were men, and those without a partner. The inhabitants of the coastal region (aPR: 0.92; 95% CI: 0.88-0.97), the Amazon (aPR 0.93; 95% CI: 0.88-0.98), and the insular region (aPR 0.76; 95% CI: 0.68-0.84) had few probabilities of being influenced by the NTL in the decision to purchase processed foods, in comparison with the residents of the highlands. Similarly, compared to non-poor people, poor people had a lower probability of being influenced by the NTL (aPR 0.89; 95% CI: 0.82-0.97). Factors associated with the influence of NTL on the decision to purchase processed foods were identified. It is recommended to reformulate and focus awareness strategies for using the NTL to purchase processed foods by taking into account the associated factors.

Abstract
BACKGROUND Limited data exist regarding how medications for pediatric use can be developed to minimize medication errors. The integrase inhibitor raltegravir was developed for use in neonates (≥2 kg). Anticipating that neonatal administration would be performed primarily by mothers with varying degrees of health literacy, a health literate, patient-focused, iterative process was conducted to update/redesign the raltegravir granules for oral suspension pediatric kit and instructions for use (IFU) for neonatal use to be ready for regulatory submission. METHODS Prototypes of an updated/redesigned raltegravir IFU were systematically assessed through multi-stage, iterative testing and evaluation involving untrained lay individuals with varying levels of health literacy, healthcare professionals and health literacy experts. RESULTS This iterative process resulted in numerous refinements to the IFU and kit, including wording, layout, presentation, colored syringes and additional instructional steps. The revised raltegravir pediatric kit and IFU (to include neonatal dosing) were approved by the US Food and Drug Administration in 2017 and the European Union in 2018. No reported medication errors related to IFU utilization had been reported as of March 2021, reflecting >3 years of commercial use worldwide. CONCLUSIONS This patient-focused process produced health literate instructions for preparing and administering an antiretroviral for neonatal use with complex dosing requirements. Testing demonstrated that lay users with a range of health literacy levels were able to accurately mix, measure and administer the product. This process demonstrates how a neonatal medication can be optimized for use through collaboration between the infectious disease expert community and a manufacturer.

Abstract
The purpose of this study was to use routine morphologic-based staining techniques to examine the histology of commercially labeled rawhide and rawhide-free dog chew products and compare the results to the product labeling. Ten dog chew products were examined by light microscopy using hematoxylin and eosin and Masson's trichrome stains. The products were labeled by the manufacturer as rawhide, beef hide, beef chew/rawhide free, and rawhide free. Four of the products were composed of two separate materials, a main chew roll and a second substance (filler) which was coated on or between the layers of the main chew roll. These materials were processed independently. Microscopically, a variety of tissues and materials were identified including collagen, skeletal muscle, fat, plant material, and starch. The products and their fillers were separated into four distinct groups based on microscopic appearance. The components identified in eight of the products appeared consistent with the product labeling. Two products labeled as rawhide free appeared similar to the dermis and this was inconsistent with product labeling. Masson's trichrome stain was not helpful in distinguishing tissue types in the tested products and this may have been due to the heat processing the products underwent during manufacturing. Bacteria and/or fungi were identified by microscopy in the H&E stained sections in four rawhide-free products.

Abstract
BACKGROUND Tobacco companies include on the packaging of their products URLs directing consumers to websites that contain protobacco messages. Online media tend to be underregulated and provide the industry with an opportunity to present users with protobacco communication. OBJECTIVE The objective of our study was to document the content of websites that were advertised on tobacco packs in 14 low- and middle-income countries. METHODS We purchased tobacco packs from 14 low- and middle-income countries in 2013 and examined them for the presence of URLs. We visited unique URLs on multiple occasions between October 1, 2016 and August 9, 2017. We developed a coding checklist and used it to conduct a content analysis of active corporate websites to identify types of protobacco communication. The coding checklist included the presence of regulatory controls and warnings, engagement strategies, marketing appeals (eg, description of product popularity, luxury/quality, taste), corporate social responsibility programs, and image management. We coded brand websites separately and also described social media and other website types. RESULTS We identified 89 unique URLs, of which 54 were active during the search period. We assessed 26 corporate websites, 21 brand websites, 2 nontobacco websites, and 5 social media pages. We excluded 2 corporate websites and 14 brand websites due to limited accessible content or incomplete content. Corporate social responsibility was discussed on all corporate websites, and marketing appeals were also common. Corporate websites were also more likely to include more nonspecific (12/24, 50%) than specific (7/24, 29%) health warnings. Promotions (6/7, 86%) and sociability appeals (3/7, 43%) were common on brand websites. The small number of social media webpages in our sample used gendered marketing. CONCLUSIONS URLs appearing on tobacco packs direct consumers to websites where users are exposed to marketing that highlights the "positive" contributions of tobacco companies on corporate websites, and extensive promotions and marketing appeals on brand websites and social media pages. It is essential that marketing regulations become more comprehensive and ban all protobacco communication, a policy that is in line with articles 5.3 and 13 of the World Health Organization Framework Convention on Tobacco Control. For countries that already ban internet tobacco advertising, enforcement efforts should be strengthened. Tobacco companies' use of URLs on packs may also be compelling for plain packaging advocacy, where all branding is removed from the pack and large graphic health warning labels are the only communication on the tobacco packaging. Future research should consider including tobacco websites in marketing surveillance.

Abstract
In the critical care of preterm infants, feeding is complex and potentially harmful to an immature gastrointestinal system. Parents have expressed the desire to be fully informed about what is being fed to their child, as this places them in the best position to nurture their child's health. In the parent-engaged setting of the Necrotizing Enterocolitis Symposium, NICU parents expressed concern and confusion about how cow's milk product and donor human milk product both carry the label "Human Milk Fortifier" (HMF). Accordingly, two online surveys were developed to characterize how the label HMF is used and interpreted in the NICU by parents and providers. Of 774 United States participants, only 21.9% of providers reported consistently describing the source of HMF to parents, and only 20.6% of parents whose child received an HMF product report knowing the source. Parents expressed that they were "not given information" regarding HMF, while both parents and healthcare providers expressed that "the label (HMF) is misleading". This study documents the ambiguity around the label HMF as well as the need for more specific language and clearer communication.

Abstract
The Cockcroft-Gault (CG) formula is recommended to guide clinicians in the choice of the appropriate dosage for direct oral anticoagulants (DOACs). However, the performance of the CG formula varies depending on the patient’s age, weight, and degree of renal function. We aimed to compare the validity of the CG formula with that of Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) and Modification of Diet in Renal Disease (MDRD) formulae for dosing DOACs. A total of 6268 consecutive patients on anticoagulants for atrial fibrillation (AF) were retrospectively investigated. Among underweight and elderly patients, the CG formula underestimated renal function compared with the non-CG formulae. However, the concordant rate of drug indications between the CG and the non-CG formulae was approximately 94%. On-label uses under the three formulae were associated with a lower risk of major bleeding (but not thromboembolism) compared to warfarin. Although we found differences in estimating renal function and the proportions of drug indications between the CG and non-CG formulae, the risks of thromboembolism and major bleeding were similar to those with warfarin regardless of which formula was used.

Abstract
Objective To determine the ability of cigarette-pack warning labels, of the minimum size required by the World Health Organization, to capture the attention of smokers and nonsmokers. Methods In this study, 30 smokers and 30 nonsmokers completed a dot-probe task in which they simultaneously observed images of cigarette packs split in two: the top contained the cigarette brand and the bottom contained the warning label. During the task, brain activity was recorded through two event-related potentials of the negative-polarity type--the potential that occurs in the posterior-contralateral zone approximately 200 ms after a stimulus (N2pc) and the sustained posterior contralateral negativity (SPCN) response--which are indicators of early and sustained attention. Results In both groups, a greater amplitude of N2pc and SPCN potentials was found for the part of the pack containing the cigarette brand. However, during the dot-probe task, reaction times were shorter for the warning label. Conclusions These results suggest that, initially, attention is focused on the cigarette brand, and only then on the warning label. The inability of warning labels to capture early-phase attention decreases their effectiveness, especially in smokers. We suggest that warning labels be enlarged to facilitate increased attention response.

Abstract
BACKGROUND Sales of charcoal dentifrices and powders have rapidly emerged into the Internet marketplace. The authors conducted a literature review to examine the efficacy and safety of charcoal and charcoal-based dentifrices. METHODS The authors searched the MEDLINE and Scopus databases for clinical studies on the use of charcoal and charcoal-based dentifrices and laboratory investigations on the bioactivity or toxicity of charcoal and charcoal-based dentifrices, published through February 2017. The authors used a defined search strategy to identify randomized, controlled clinical trials with a follow-up duration of 3 months or longer. In addition, the authors selected the first 50 consecutive charcoal dentifrices from Google.com and Amazon.com for ascertainment of product assortment and advertising promotions. RESULTS The authors' literature search identified 118 potentially eligible articles. Thirteen studies reported brushing the teeth with raw charcoal or soot; however, none of these studies met the inclusion criteria. Two studies offered nonspecific caries reductions, 3 studies reported deleterious outcomes (increased caries, enamel abrasion, nonquantified negative impact), and 1 study indicated only that brushing with raw charcoal had no adverse effects on oral hygiene. Seven other studies reported only on the use of charcoal for oral hygiene. Internet advertisements included unsubstantiated therapeutic claims-such as antibacterial, antifungal, antiviral, and oral detoxification, as well as potentially misleading product assertions. One-third of the charcoal dentifrices contained bentonite clay, and 1 contained betel leaves. CONCLUSIONS The results of this literature review showed insufficient clinical and laboratory data to substantiate the safety and efficacy claims of charcoal and charcoal-based dentifrices. Larger-scale and well-designed studies are needed to establish conclusive evidence. PRACTICAL IMPLICATIONS Dental clinicians should advise their patients to be cautious when using charcoal and charcoal-based dentifrices with unproven claims of efficacy and safety.

Abstract
Green products are appealing. Thus, labeling products as environmentally friendly is an effective strategy to increase sales. However, the labels often promise more than the products can actually deliver. In the present research, we examined the expectation that consumers with high ecological motivation have strong preferences for green-labeled products – even when presented product information contradicts the label’s image. This unsettling hypothesis is grounded in the labels’ potential to create a cognitive match between the labeled product and consumers’ motives. For labels indicating environmental friendliness (green product labels), this link should be strongest when consumers’ ecological motivation is high. Findings in a series of three experiments support our assumption, showing that consumers with high ecological motivation had strong preferences (i.e., product evaluations, purchase intentions, and simulated purchase decisions) for green-labeled products as compared to consumers with low ecological motivation (Studies 1–3). Crucially, these preferences were robust, despite contradicting environmental product information (Studies 1 and 2). We extended our findings by additionally examining the impact of product labels and motivation on moral self-regulation processes. This was established by assessing participants’ pro-social behavior after the purchase task: participants with high ecological motivation acted, consistent with their motives, more pro-socially in post-decision occasions. In accordance with moral cleansing effects, pro-social behavior was intensified after purchasing conventional products (Studies 2 and 3). Green labels protected participants with high ecological motivation from moral threats due to the purchase, thus making pro-social behavior less likely. Findings suggest that highly ecologically motivated consumers are most susceptible to green labels, which may override detailed product information.

Abstract
CONTEXT AND OBJECTIVES Package leaflets are necessary for safe use of medicines. The aims of the present study were: 1) to assess the compliance between the content of the package leaflets and the specifications of the pharmaceutical regulations; and 2) to identify potential safety issues for patients. DESIGN AND SETTING Qualitative descriptive study, involving all the package leaflets of branded medicines from the three most consumed therapeutic groups in Portugal, analyzed in the Department of Pharmacoepidemiology, School of Pharmacy, University of Lisbon. METHODS A checklist validated through an expert consensus process was used to gather the data. The content of each package leaflet in the sample was classified as compliant or non-compliant with compulsory regulatory issues (i.e. stated dosage and descriptions of adverse reactions) and optional regulatory issues (i.e. adverse reaction frequency, symptoms and procedures in cases of overdose). RESULTS A total of 651 package leaflets were identified. Overall, the package leaflets were found to be compliant with the compulsory regulatory issues. However, the optional regulatory issues were only addressed in around half of the sample of package leaflets, which made it possible to identify some situations of potentially compromised drug safety. CONCLUSION Ideally, the methodologies for package leaflet approval should be reviewed and optimized as a way of ensuring the inclusion of the minimum essential information for safe use of medicines.

Abstract
OBJECTIVE Evaluate the effect of the first pictorial warning labels on cigarette packs in Mexican smokers. MATERIALS AND METHODS A population-based representative cohort of smokers from seven Mexican cities was surveyed before (2010) and after (2011) the implementation of pictorial warning labels. To determine the change variables representing the cognitive and behavioral impact of pictorial warnings, bivariate and adjusted generalized estimating equations were estimated. Data from the second survey (2011) were analyzed to determine the factors associated with aided recall of specific pictorial warnings, as well as the factors associated with self-report of the impact that these warnings had. RESULTS From 2010 to 2011, significant increases were found in smoker's knowledge about smoking risks, the toxic components of tobacco, and the quitline number for receiving cessation assistance. Recall and impact of specific pictorial warnings was generally broad and equally distributed across the smoker population. In comparison with recent ex-smokers interviewed in 2010, more recent ex-smokers in 2011 reported that pack warnings had influenced their decision to quit (RM=2.44, 95% IC 1.27-4.72). CONCLUSION The first pictorial warning labels on cigarette packages in Mexico have had a significant impact on knowledge and behavior.

Abstract
OBJECTIVE The objective of this study was to determine the most effective content of pictorial health warning labels (HWLs) and whether educational attainment moderates these effects. METHODS Field experiments were conducted with 529 adult smokers and 530 young adults (258 nonsmokers; 271 smokers). Participants reported responses to different pictorial HWLs printed on cigarette packages. One experiment involved manipulating textual form (testimonial narrative vs. didactic) and the other involved manipulating image type (diseased organs vs. human suffering). RESULTS Tests of mean ratings and rankings indicated that pictorial HWLs with didactic textual forms had equivalent or significantly higher credibility, relevance, and impact than pictorial HWLs with testimonial forms. Results from mixed-effects models confirmed these results. However, responses differed by participant educational attainment: didactic forms were consistently rated higher than testimonials among participants with higher education, whereas the difference between didactic and testimonial narrative forms was weaker or not statistically significant among participants with lower education. In the second experiment, with textual content held constant, greater credibility, relevance, and impact was found for graphic imagery of diseased organs than imagery of human suffering. CONCLUSIONS Pictorial HWLs with didactic textual forms seem to work better than those with testimonial narratives. Future research should determine which pictorial HWL content has the greatest real-world impact among consumers from disadvantaged groups, including assessment of how HWL content should change to maintain its impact as tobacco control environments strengthen and consumer awareness of smoking-related risks increases.

Abstract
OBJECTIVE To assess the impact of different health warning labels (HWL). MATERIAL AND METHODS Data from the International Tobacco Control Survey (ITC Survey) were analyzed from adult smokers in Brazil, Uruguay and Mexico, each of which used a different HWL strategy (pictures of human suffering and diseased organs; abstract pictorial representations of risk; and text-only messages, respectively). Main outcomes were HWL salience and cognitive impact. RESULTS HWLs in Uruguay (which was the only country with a HWL on the front of the package) had higher salience than either Brazilian or Mexican packs. People at higher levels of educational attainment in Mexico were more likely to read the text-only HWLs whereas education was unassociated with salience in Brazil or Uruguay. Brazilian HWLs had greater cognitive impacts than HWLs in either Uruguay or Mexico. HWLs in Uruguay generated lower cognitive impacts than the text-only HWLs in Mexico. In Brazil, cognitive impacts were strongest among smokers with low educational attainment. CONCLUSIONS This study suggests that HWLs have the most impact when they are prominent (i.e., front and back of the package) and include emotionally engaging imagery that illustrates negative bodily impacts or human suffering due to smoking.

Abstract
Dietary supplement use has increased exponentially in recent years despite the lack of regulatory oversight and in the face of growing safety concerns. This paper provides an overview of the public health implications and safety concerns associated with dietary supplement use, especially by cancer patients. Botanical research is actively pursued at the Memorial Sloan-Kettering Cancer Center (MSKCC) Integrative Medicine department. Work of the MSKCC Center for the Study of Botanical Immunomodulators is described, and guidelines for cancer patients' use of dietary supplements outlined. Herbs and other botanicals are complex, physiologically active agents, but little is known about most of the popular, widely available dietary supplements. Herb-drug interactions, a major concern, are exacerbated in the cancer setting. Biologically active agents may interfere with chemotherapy and other prescription medications. They may exert anti-coagulant activity at rather inconvenient times such as during surgery, and create other serious problems. Research on the bioavailability, effective dosage, safety and benefits of these complex agents is sorely needed. Oncology professionals and other healthcare providers should educate themselves and their patients about these issues. Probably the largest, continuously-updated free information resource is MSKCC's AboutHerbs website (www.mskcc.org/AboutHerbs).
