Review
Mentha (also known as peppermint), a genus of plants in the taxonomic family Lamiaceae (mint family), is widely distributed throughout temperate regions of the world. Mentha contains various constituents that are classified as peppermint essential oil (PEO) and non-essential components. PEO, consisting mainly of menthol, menthone, neomenthol and iso-menthone, is a mixture of volatile metabolites with anti-inflammatory, antibacterial, antiviral, scolicidal, immunomodulatory, antitumor, neuroprotective, antifatigue and antioxidant activities. Mounting evidence indicates that PEO may pharmacologically protect gastrointestinal, liver, kidney, skin, respiratory, brain and nervous systems, and exert hypoglycemic and hypolipidemic effects. Clinically, PEO is used for gastrointestinal and dermatological diseases, postoperative adjuvant therapy and other fields. This review aims to address the advances in the extraction and isolation of PEO, its biological activities, pharmacological effects, toxicity and applications, with an emphasis on the efficacy of PEO on burn wounds and psoriasis, providing a comprehensive foundation for research, development and application of PEO in future.

Review
BACKGROUND
Medication administration errors (MAEs) cause preventable patient harm and cost billions of dollars from already-strained healthcare budgets. An emerging factor contributing to these errors is nurse fatigue. Given medication administration is the most frequent clinical task nurses undertake; it is vital to understand how fatigue impacts MAEs.
OBJECTIVE
Examine the evidence on the effect of fatigue on MAEs and near misses by registered nurses working in hospital settings.
METHOD
Arksey and O'Malley's scoping review framework was used to guide this review and PAGER framework for data extraction and analysis. The PRISMA checklist was completed. Four electronic databases were searched: CINAHL, PubMed, Scopus and PsycINFO. Eligibility criteria included primary peer review papers published in English Language with no date/time limiters applied. The search was completed in August 2021 and focussed on articles that included: (a) registered nurses in hospital settings, (b) MAEs, (c) measures of sleep, hours of work, or fatigue.
RESULTS
Thirty-eight studies were included in the review. 82% of the studies identified fatigue to be a contributing factor in MAEs and near misses (NMs). Fatigue is associated with reduced cognitive performance and lack of attention and vigilance. It is associated with poor nursing performance and decreased patient safety. Components of shift work, such as disruption to the circadian rhythm and overtime work, were identified as contributing factors. However, there was marked heterogeneity in strategies for measuring fatigue within the included studies.
RELEVANCE TO CLINICAL PRACTICE
Fatigue is a multidimensional concept that has the capacity to impact nurses' performance when engaged in medication administration. Nurses are susceptible to fatigue due to work characteristics such as nightwork, overtime and the requirement to perform cognitively demanding tasks. The mixed results found within this review indicate that larger scale studies are needed with particular emphasis on the impact of overtime work. Policy around safe working hours need to be re-evaluated and fatigue management systems put in place to ensure delivery of safe and quality patient care.

The transient receptor potential melastatin 8 (TRPM8) channel is the primary molecular transducer responsible for the cool sensation elicited by menthol and cold in mammals. TRPM8 activation is controlled by cooling compounds together with the membrane lipid phosphatidylinositol 4,5-bisphosphate (PIP). Our knowledge of cold sensation and the therapeutic potential of TRPM8 for neuroinflammatory diseases and pain will be enhanced by understanding the structural basis of cooling agonist- and PIP-dependent TRPM8 activation. We present cryo-electron microscopy structures of mouse TRPM8 in closed, intermediate, and open states along the ligand- and PIP-dependent gating pathway. Our results uncover two discrete agonist sites, state-dependent rearrangements in the gate positions, and a disordered-to-ordered transition of the gate-forming S6-elucidating the molecular basis of chemically induced cool sensation in mammals.

Herbal treatments are often used as a treatment for migraine. Therefore, an evaluation of their safety and efficacy is important. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and Cochrane Collaboration's tool for assessing the risk of bias, a systematic literature review of randomised, controlled human trials assessing the effects of herbal treatments delivered as a single ingredient for the acute or prophylactic treatment of migraine were conducted. Studies were identified through electronic database searches on Medline (Pubmed), Cochrane Library, Scopus, and CINAHL. Nineteen studies were identified examining the effects on migraine of feverfew, butterbur, curcumin, menthol/peppermint oil, coriander, citron, Damask rose, chamomile, and lavender. Overall, findings on the efficacy of feverfew were mixed and there was positive, albeit limited evidence for butterbur. There were positive, preliminary findings on curcumin, citron, and coriander as a prophylactic treatment for migraine, and the use of menthol and chamomile as an acute treatment. However, the risk of bias was high for many studies. The results of this systematic review suggest that several herbal medicines, via their multifactorial physiological influences, present as potential options to enhance the treatment of migraine. However, further high-quality research is essential to examine their efficacy and safety as a treatment for migraine.

Review
INTRODUCTION
Oral Nicotine Pouches (ONPs) are the new form of nicotine pouches that have become a type of emerging smokeless tobacco product sold by various tobacco companies. These smokeless tobacco products are marketed for usage all over as snus containing tobacco-derived nicotine (natural) or as tobacco-free nicotine (synthetic) as substitutes for other tobacco products. Based on perception and socio-behavioral aspects, ONPs have become popular tobacco products among adolescents/young adults, and over 50% of young adult users of ONP use flavored ONPs, such as menthol/mint, tobacco, dessert/candy, and fruity, which are the most popular flavors. Various new ONP flavors are currently popular locally as well as in the online market. Tobacco, menthol, and fruit-flavored ONPs could motivate cigarette smokers to change to ONPs.
METHODS
We expanded our knowledge on natural/synthetic ONP flavor wheels to available data on ONPs, describing, in detail, their flavors and brands (US and Europe) in both natural and synthetic ONP categories. We classified over 152 snus and 228 synthetic ONPs into the following flavor categories: "Tobacco", "Menthol/Mint", "Fruity", "Candy/Deserts", "Drink", "Aroma", "Spices", and "Mixed Flavors".
RESULTS
Based on total numbers, we found the most popular ONP flavors, sold as tobacco and menthol, to be among natural ONPs; among synthetic ONPs, fruity and menthol are the most prominent flavors, with varying concentrations of nicotine and other flavoring chemicals, including coolant WS-23. We also showed possible molecular targets and toxicities, due to exposure to ONPs, activating several signaling cascades such as AKT and NF-kappaB, which might possibly lead to apoptosis and epithelial mesenchymal transition (EMT).
CONCLUSIONS
Considering the marketing of ONP products with various flavor profiles and with most of these products containing tobacco/menthol/fruit flavor, it is likely to have regulation and a marketing disclaimer on some of these products. Further, it would be logical to determine how the market reacts in terms of compliance and non-compliance with flavor restrictions by the regulatory agencies.

BACKGROUND
Menthol cigarette use among women who smoke cigarettes during pregnancy is high, but little is known about the factors that contribute to preference for menthol cigarette use during pregnancy.
OBJECTIVE
This study investigated preferences, perceptions, and intentions to use menthol vs. non-menthol cigarettes in a sample of pregnant women.
METHODS
Pregnant women ( = 124, = 26.2 years, 50% minorities) completed a study investigating the impact of maternal smoking on biobehavioral markers of fetal risk. During the third trimester, participants self-reported preferences (liking, attractiveness, smoothness, interest), perceptions of harm (general, pregnancy-specific), and intentions to use menthol and non-menthol cigarettes. We examined differences in responses based on whether participants endorsed (1) cigarette use during pregnancy (yes/no) and (2) lifetime cigarette use (yes/no).
RESULTS
Sixty-two participants endorsed cigarette smoking during pregnancy (85.5% smoked menthol cigarettes), and 94 participants reported lifetime use. Overall, menthol cigarettes were perceived as more likeable and smoother vs. non-menthol (s < .001) - even among participants who never smoked cigarettes (s < .05). All participants rated both menthol and non-menthol cigarette use as harmful. Compared to participants who did not smoke during pregnancy, participants who smoked during pregnancy rated menthol cigarettes as less harmful for pregnant women ( = .001), while there were no differences between groups in harm perceptions toward non-menthol cigarettes.
CONCLUSIONS
Menthol may increase cigarettes appeal for pregnant women. Implications for regulation of menthol cigarettes are discussed. Future studies may investigate the role of sensory perception, marketing, and health education in influencing these factors.

Nicotine & Tobacco Research : Official... Jan 2021To study the association between health care utilization and menthol cigarette use and whether the association differed between African American (AA) and non-AA smokers.
INTRODUCTION
To study the association between health care utilization and menthol cigarette use and whether the association differed between African American (AA) and non-AA smokers.
METHODS
We analyzed the three most recent 2005, 2010, and 2015 National Health Interview Survey Cancer Control Supplements. After incorporating propensity score weights adjusting for observed differences between menthol and non-menthol users, we estimated Zero-Inflated Poisson models on hospital nights, emergency department visits, doctor visits, and home visits as a function of menthol use status and other covariates separately for current cigarette smokers and recent quitters (former smokers quitting cigarette smoking ≤ 4 years).
RESULTS
Although current menthol smokers smoked fewer cigarettes per day than current non-menthol smokers, they did not differ from current non-menthol smokers in health care utilization. Among recent quitters, those who used to smoke menthol cigarettes had higher odds of having hospital nights than those who used to smoke non-menthol cigarettes. However, we did not find any significant association between menthol use and other health care utilization-emergency department visits, doctor visits, and home visits-among recent quitters. Moreover, compared with non-AA recent quitters, AA recent quitters had higher odds of having home visits, but fewer home visits, if they used to smoke menthol cigarettes.
CONCLUSION
Menthol use was associated with greater hospitalization among recent quitters, and the association between home visits and menthol use differed between AA and non-AA recent quitters.
IMPLICATIONS
This is the first study that used econometric models to study the association between health care utilization and menthol cigarette use and examine whether the association differed between AA and non-AA smokers. Our study found health care utilization did not differ by menthol use status for current smokers, although current menthol smokers smoked fewer cigarettes per day than current non-menthol smokers. However, we found menthol use was associated with higher odds of having hospital nights for recent quitters. We also found AA recent quitters had a different association between home visits and menthol use compared with non-AA recent quitters.

Measures to ban or restrict menthol and other flavours in tobacco products are under consideration or newly implemented in an increasing number of jurisdictions across the world. As one of the world leaders, Canada's experience in successfully developing and implementing such measures can be instructive for other jurisdictions. This paper explores the history of how Canada was able to implement tobacco flavour bans including menthol, examines some of the challenges and presents lessons learnt for other jurisdictions. The crucial motivation for these bans emerged from surveillance data showing high rates of flavoured tobacco use by youth, including menthol cigarette smoking, that was publicised by non-governmental organisations. Further data showed that early legislation in 2009 contained loopholes (cigar size exemptions and menthol exemptions) that limited the benefits of the legislation. Leadership by the provinces created an environment in which the federal ban on menthol ingredients in 2017 was a clear and obvious step to ensure implementation across the country. The Canadian measures have been successful at reducing the use of flavoured tobacco including menthol cigarettes and facilitating smoking cessation. Lessons learnt include the downsides of exemptions, the lack of a contraband issue (despite an existing supply in Canada), the benefits of availability of youth flavour prevalence data and the success of subnational regulations to advance national regulation.

It has been reported that Sanoshashinto (SanHuangXieXinTang, ), which is composed of Rhei Rhizoma, Scutellariae Radix, and Coptidis Rhizoma, exhibits vasorelaxant effects in vitro and lowers blood pressure of patients. Based on this discovery, in this study, a mixture containing those three materials and combinations of them were extracted with methanol, and the extracts were fractionated into different parts. Effects of all extracts and fractions on high concentration of potassium chloride (High K)- or noradrenaline (NA)-induced contractions of isolated rat aortic rings or helical strips were examined. Qualitative and quantitative HPLC analyses of the extracts and the fractions revealed that the contents of baicalin and berberine in Sanoshashinto methanol extract (SHXXTM) were higher than those of the other constituents. All pharmacological and HPLC data were analyzed by principal component analysis (PCA) software and the results indicated that baicalin, berberine, palmatine, baicalein, and wogonoside contributed significantly to the pharmacological activity. Furthermore, spontaneously hypertensive rats (SHRs) that were orally given SHXXTM or a baicalin-berberine combination showed significantly reduced increase in the rate of systolic blood pressure (SBP) compared to the control group. These findings suggested that Sanoshashinto has significant vasorelaxant effects in vitro and antihypertensive effects in vivo, and baicalin and berberine, which were the principal constituents of Scutellariae Radix and Coptidis Rhizoma, were the main antihypertensive constituents in Sanoshashinto. It was speculated that baicalin and berberine produced vasorelaxant effects by activating the NO/cGMP pathway and that the BK channel and the DAG/PKC/CPI-17 pathway were also involved.
