RESUMEN
The health benefits of nut consumption have been extensively demonstrated in observational studies and intervention trials. Besides the high nutritional value, countless evidences show that incorporating nuts into the diet may contribute to health promotion and prevention of certain diseases. Such benefits have been mostly and certainly attributed not only to their richness in healthy lipids (plentiful in unsaturated fatty acids), but also to the presence of a vast array of phytochemicals, such as polar lipids, squalene, phytosterols, tocochromanols, and polyphenolic compounds. Thus, many nut chemical compounds apply well to the designation "nutraceuticals," a broad umbrella term used to describe any food component that, in addition to the basic nutritional value, can contribute extra health benefits. This contribution analyses the general chemical profile of groundnut and common tree nuts (almond, walnut, cashew, hazelnut, pistachio, macadamia, pecan), focusing on lipid components and phytochemicals, with a view on their bioactive properties. Relevant scientific literature linking consumption of nuts, and/or some of their components, with ameliorative and/or preventive effects on selected diseases - such as cancer, cardiovascular, metabolic, and neurodegenerative pathologies - was also reviewed. In addition, the bioactive properties were analyzed in the light of known mechanistic frameworks.

INTRODUCTION: Pregnancy is an important period of life for women and their husbands as the couple's health is essential. The present study evaluated the impact of some factors (marital adjustment with depressive symptoms) on health-promoting behaviors in pregnant women and their husbands based on the actor-partner interdependence model (APIM). MATERIALS AND METHODS: This descriptive study examined 211 couples (pregnant women and their husbands) in pregnancy clinics of Babol University of Medical Sciences using a convenience sampling method. The participants completed Spanier's Dyadic Adjustment Scale (DAS) (1979), Edinburgh Postnatal Depression Scale (EPDS) (1987), and Walker's Health Promoting Lifestyle Profile II (HPLPII) questionnaire (1997). The relationships between women and their husbands were also evaluated using structural equation modeling with R software according to the Lavaan (latent variable analysis) package based on APIM-SEM. RESULTS: The pregnant women's marital adjustment positively affected their health-promoting behaviors (ß = 0.456, 95% Cl: 0.491-0.998, p < 0.001) and their husbands' (ß = 0.210, 95% Cl: 0.030-0.726, p = 0.048). Pregnant woman's depressive symptoms also negatively affected their health-promoting behaviors (ß=-0.088, 95% Cl: -0.974-0.074, P = 0.236) and their husbands' health-promoting behaviors (ß=-0.177, 95% Cl: -0.281 - -0.975, P = 0.011). Furthermore, the husband's marital adjustment only positively affected his studied behaviors (ß = 0.323, 95% Cl: 0.0303-0.895, P < 0.001) but did not affect the pregnant woman's health behaviors. The husband's depressive symptoms had a negative impact on his studied behaviors (ß = 0.219, 95% Cl: -0.122 - -0.917, P = 0.001) and did not affect the pregnant woman's depressive symptoms. Our findings confirmed the mediating role of depressive symptoms in pregnant women and their husbands on the association of marital adjustment and health-promoting behaviors. According to the actor-partner study, a pregnant woman's marital adjustment scores positively affected her studied behaviors and her husband (ß = 0.071, 95% Cl: 0.042-0.278, P = 0.015) by decreasing her depression score. Therefore, the husband's marital adjustment score positively affected his studied behaviors by decreasing his depression score (ß = 0.084, 95% Cl: -0.053 -0.292, P = 0.005), and it did not affect his wife's health-promoting behaviors. DISCUSSION AND CONCLUSION: These findings suggest healthcare providers, obstetricians, and psychologists evaluate the husbands' symptoms of depression and health-promoting behaviors in the routine pregnancy care of pregnant women. They also pay great attention to marital adjustment as a determinant of reducing depressive symptoms in pregnant women and their husbands.

BACKGROUND: With the global population growing older, there is a need for more knowledge of how to improve and/or maintain functional capacities to promote healthy ageing. In this study we aimed to assess the effect of several known health-promoting behaviors in old age with intrinsic capacity ten years later. METHODS: This was a prospective cohort study looking at participants that were ≥ 65 years at the time of the third wave of the Trøndelag Health Study (HUNT3, 2006-2008) who also took part in the 70 + sub-study of the fourth wave (HUNT4 70+, 2017-2019). Self-reported behavior data from short questionnaires, including diet and physical activity, were collected in HUNT3, and data on the five domains of intrinsic capacity defined by the World Health Organization were collected in HUNT4 70+. A composite index was created for both healthy life and intrinsic capacity, awarding points for how well participants adhered to guidelines for healthy living and their level of functional impairment, respectively. Ordinal logistic regression was used to assess the relationship between health-promoting behaviors and intrinsic capacity. RESULTS: Of 12,361 participants in HUNT3 ≥ 65 years, 4699 (56.5% women) also participated in HUNT4 70+. On the health-promoting behaviors, lowest adherence to healthy living guidelines were seen for fruit and vegetables intake (47.2%), milk intake (46.7%) and physical activity (31.1%). On intrinsic capacity domains, highest impairment was seen in the domains of locomotion (29.7%), hearing (11.1%) and vitality (8.3%). A higher adherence to guidelines for healthy living was associated with higher intrinsic capacity 10 years later. A one-point increase in the healthy life index was associated with a 1.15 (95% confidence interval 1.10-1.21) times increased odds of being in a higher intrinsic capacity category. CONCLUSION: Health-promoting behaviors in old age are associated with better intrinsic capacity ten years later. In clinical settings assessment of health-promoting behaviors could potentially be done using short questionnaires.

BACKGROUND: Low income communities are vulnerable to non-communicable diseases (NCDs), which affect their economy and disability status. An effective approach to address the NCD burden is through the multidimensional concept of health-promoting lifestyle. Another preferred approach by the population worldwide for NCD treatment is natural health product (NHP). Studies on NHP and health-promoting lifestyle among this vulnerable population, specifically the low-income urban community, are limited. Therefore, this study, aimed at investigating the NHP knowledge and health-promoting lifestyle, and to determine the factors associated with health-promoting lifestyle in a low income urban community in Cheras, Kuala Lumpur. This study has focused on sociodemographic characteristics, annual health monitoring activities, and health status, which are modifiable and non-modifiable factors. METHODS: Phase 1 of the study involves developing the Malay-version NHP knowledge questionnaire, whereas Phase 2 involves a cross-sectional study of 446 randomly selected low-income respondents to determine their level of health-promoting lifestyle and the associated factors. The respondents' sociodemographic, socioeconomic, health monitoring activity, health status, and NHP knowledge data were obtained using the newly developed Malay-version NHP questionnaire and the Health-Promoting Lifestyle Profile II (HPLP II) questionnaire. The independent variables include sociodemographic status, annual health monitoring activities, health status and NHP knowledge were analysed using simple and multiple linear regression. RESULTS: In this study, the 10-item NHP knowledge questionnaire developed in the Malay version contains two domains [safe use (eight items) and point of reference (two items)] (total variance explained: 77.4%). The mean of NHP knowledge score was 32.34 (standard deviation [SD] 7.37). Meanwhile, the mean score of health-promoting lifestyle was 109.67 (SD 25.01). The highest and lowest scores of health-promoting lifestyles are attributed to spiritual growth and physical activity, respectively. Ethnicity is associated with a higher health-promoting lifestyle level, same goes to the occupational status - NHP knowledge interaction. "Unclassified" education status and annual blood glucose level monitoring are associated with a lower level of health-promoting lifestyle. CONCLUSION: A new questionnaire in Malay version was developed to measure NHP knowledge. Compared to other subpopulations, the respondents' health-promoting lifestyle levels in this study were low, associated with ethnicity, education status, and health monitoring activities. The findings provided insight into the interaction between NHP knowledge and occupational status, which is associated with a higher health-promoting lifestyle level. Accordingly, the future health-promoting lifestyle intervention programmes in healthcare delivery should target these factors.

BACKGROUND: Self-initiated and proactive changes in working conditions through crafting are essential for shaping work and improving work-related well-being. Recently, the research stream of job crafting has been extended to other life domains. The present paper aims to study a novel crafting concept-work-nonwork balance crafting-investigating the role of its antecedents and identifying relevant outcomes. Work-nonwork balance crafting is defined as individuals' unofficial techniques and activities to shape their work-nonwork balance, here considering their life domain boundary preferences. METHODS: In the study, 1,060 employees in three European countries (Austria, Germany and Switzerland) were surveyed in a longitudinal three-wave study with three-month intervals. We explored the influences of job/home demands and resources as antecedents of work-nonwork balance crafting. Important constructs for employee health and well-being (i.e., work engagement, work-related burnout, mental well-being and detachment from work) were investigated as outcomes. RESULTS: The findings suggest that resources and demands in the context of work or home are key antecedents of work-nonwork balance crafting. Work-nonwork balance crafting was also predictive for important employee health and well-being outcomes over three months, mainly in a positive and health-promoting way. CONCLUSION: This study provides insights into the antecedents of proactive efforts to balance the complex interplay of life domains. By studying work-nonwork balance crafting, we provide a new perspective on crafting beyond job crafting, which may help maintain or improve employees' mental health and well-being.

BACKGROUND: The popularization of the internet and rapid development of mobile devices have led to an increased inclination and opportunities to obtain health-related information online. The eHealth Literacy Scale (eHEALS), widely used for measuring eHealth literacy, assesses an individual's ability to search, understand, appraise, and use eHealth information. However, the Chinese version of the eHEALS multiple-factor model remains to be validated, and the correlation between eHEALS and the health-promoting lifestyle profile (HPLP) among university students is rarely explored in Taiwan. OBJECTIVE: This study aimed to examine the fit, validity, and reliability of the Chinese eHEALS multiple-factor model and to clarify the predictive effects of eHEALS on the HPLP among university students. METHODS: University students in Taipei, the capital of Taiwan, were recruited, and 406 valid questionnaires including sociodemographic characteristics, eHEALS, and HPLP responses were collected. Confirmatory factor analysis was performed to validate the Chinese eHEALS. Independent sample t test, 1-way ANOVA, and multiple linear regression analyses were conducted to examine the relationship between sociodemographic variables and the HPLP. Pearson product-moment correlation and binary logistic regression analyses were performed to ascertain the predictive effects of eHEALS on the HPLP. RESULTS: The Chinese eHEALS exhibited an optimal fit when delineated into the search, usage, and evaluation 3-factor model (comparative fit index=0.991, Tucker-Lewis index=0.984, root mean square error of approximation=0.062), and its validity and reliability were confirmed. The mean eHEALS score of university students was 3.17/4.00 (SD 0.48) points, and the score for the evaluation subscale was the lowest (mean 3.08, SD 0.56 points). Furthermore, there were significant sex, institution orientation, daily reading time, daily screen time, primary information channel, and perceived health status differences in the HPLP: male participants (t404=2.346, P=.02), participants attending general university (t404=2.564, P=.01), those reading ≥1 hour daily (F2,403=17.618, P<.001), those spending <3 hours on mobile devices or computers daily (F2,403=7.148, P<.001), those acquiring information from others (t404=3.892, P<.001), and those with a good perceived health status (F2,403=24.366, P<.001) had a significantly higher score. After adjusting for sociodemographic variables, the eHEALS score remained an independent predictor of the HPLP. Compared to students with relatively high eHEALS scores, those with relatively low eHEALS scores had a 3.37 times risk of a negative HPLP (adjusted odds ratio [OR]=3.37, 95% CI 1.49-7.61), which could explain 14.7%-24.4% of the variance (Cox-Snell R2=0.147, Nagelkerke R2=0.244, P=.004). CONCLUSIONS: There is room for improvement in eHealth literacy among university students in Taipei. eHEALS may be used to screen students who require HPLP improvement, thereby providing appropriate eHealth literacy training programs, particularly those targeting evaluation literacy. Additionally, the 3-factor model of the Chinese eHEALS used in this study results in more definite scale content, thus increasing the practicality and applicability of this scale in health-promoting studies.

Sugar-sweetened beverages (SSBs) are drinks that contain added sugar or sweeteners and provide calories with no additional nutrients, and some countries have imposed additional taxes on the SSBs to reduce consumption, which is considered an SSB tax policy. This study used a cross-sectional online survey to examine the patterns of public support for an SSB tax in Taiwan. The sample included 1617 adults aged ≥ 20 years, who answered the survey questionnaire between May 2020 and April 2021. The respondents were recruited using convenience sampling, but sampling weights were applied to represent the Taiwanese population. Generalized ordered logit models with sampling weights were used to examine the correlates of public support for an SSB tax. Results showed that ~60% of the respondents supported the SSB tax and 47% perceived the tax to be effective. The respondents who were aware of the perceived health risks of SSBs or those who believed that one should be partly responsible for the health impact of SSBs were more likely to show support for the SSB tax. In adjusted regression models, both one's perceived risk and perceived responsibility of SSBs were positively associated with the perceived effectiveness of the SSB tax after sociodemographic characteristics were controlled. These research findings show evidence that there is public support for implementing an SSB tax to reduce SSB consumption in Taiwan.

THE AIM: To explore and describe workplace stress levels and health-promoting behaviours reported by emergency nurses in China, and to investigate factors associated with workplace stress and health-promoting lifestyle behaviours among emergency nurses. METHODS: A cross-sectional study was conducted between October 2019 and January 2020. Nurses (n = 1565) were recruited from the emergency departments of 54 hospitals within the Sichuan Province of West China. Each subject completed the Chinese versions of the Nurse Workplace Stress Scale, the Health-Promoting Lifestyle Profile (HPLP-II) and demographic questions. Linear regression analyses were used to identify associations between workplace stress and the health-promoting lifestyle and risk factors correlated with these two measurements. RESULTS: Workplace stress was negatively associated with health-promoting behaviours. Linear regression analysis showed that gender, marital status, whether wages met expected standards and professional rank were found to be associated with health promotion behaviours; marital status, whether income met expected standards, the number of night shifts per month and health promotion behaviours were found to be associated with workplace stress. CONCLUSION: Higher levels of workplace stress are associated with lower levels of engagement in health-promoting behaviours, suggesting the potential for reducing workplace stress through the adoption of healthier habits. Policies should prioritize workplace stress by promoting healthy lifestyle initiatives.
RESUMEN
Natural products and their bioactive compounds have been used for centuries to prevent and treat numerous diseases. Kaempferol, a flavonoid found in vegetables, fruits, and spices, is recognized for its various beneficial properties, including its antioxidant and anti-inflammatory potential. This molecule has been identified as a potential means of managing different pathogenesis due to its capability to manage various biological activities. Moreover, this compound has a wide range of health-promoting benefits, such as cardioprotective, neuroprotective, hepatoprotective, and anti-diabetic, and has a role in maintaining eye, skin, and respiratory system health. Furthermore, it can also inhibit tumor growth and modulate various cell-signaling pathways. In vivo and in vitro studies have demonstrated that this compound has been shown to increase efficacy when combined with other natural products or drugs. In addition, kaempferol-based nano-formulations are more effective than kaempferol treatment alone. This review aims to provide detailed information about the sources of this compound, its bioavailability, and its role in various pathogenesis. Although there is promising evidence for its ability to manage diseases, it is crucial to conduct further investigations to know its toxicity, safety aspects, and mechanism of action in health management.

Research background: Mango peel is a production waste and can cause environmental problems, but its nutritional value consists of bioactive compounds that could be beneficial for human health. The aim of this study is to determine the bioactive compounds, antioxidant and anti-inflammatory activities of mango peels and their use in muffins. Experimental approach: The content of polyphenols, carotenoids and total phenols as well as the antioxidant activity of mango peel extract were evaluated. The anti-inflammatory activity of the extract was investigated using Caco-2 cell assay. The mango peel powder was then incorporated into muffin formulations. The sensory properties of these fortified muffins were evaluated. The total phenolic content, antioxidant activity and anti-inflammatory properties of the muffin extracts and their bioaccessible fractions were also analysed. Results and conclusions: The mango peel contained quercetin, phenolic compounds, α-carotene, ß-carotene and lutein, which have antioxidant potential. In Caco-2 cells exposed to induced inflammation, the mango peel powder extract (γ=10, 50 and 100 µg/mL) attenuated the production of reactive oxygen species (ROS), tumour necrosis factor-alpha (TNF-α) and interleukin-8 (IL-8), while maintaining cell viability. Muffins supplemented with 5 % mango peel powder showed good sensory properties, but not as good as those of plain muffins without mango peel powder. The total phenolic content and antioxidant activities in both the extract and the bioaccessible fraction of the supplemented muffins were higher than those observed in the standard muffins. Moreover, the extract and bioaccessible fraction of the supplemented muffins resulted in a higher reduction of ROS, IL-8 and TNF-α production in Caco-2 cells than those obtained from the standard muffins. Novelty and scientific contribution: This study is the first to investigate the protective effects of mango peel and muffins supplemented with mango peel powder against IL-1ß-induced oxidative damage in Caco-2 cells. The results confirm that both mango peel and the supplemented muffins inhibited the production of inflammatory markers, including ROS and cytokines. These findings suggest that mango peel could be a valuable component of functional food formulations including dietary supplements.
RESUMEN
BACKGROUND: Polygonatum kingianum Coll. & Hemsl (PK), a prominent medicine and food homology plant, has been consumed as a decoction from boiling water for thousands of years. 'Nine Steaming Nine Sun-drying' processing has been considered an effective method for enriching tonic properties, but studies investigating such impacts on PK and underlying mechanisms are extremely rare. RESULTS: We first demonstrated substantial improvements in the anti-oxidative, anti-inflammatory and anti-hyperglycemia effects of the Nine Steaming Nine Sun-drying processed PK water extracts compared with crude PK in cell models (i.e., HepG2 and Raw 264.7 cells). We then integrated foodomics and network pharmacology analysis to uncover the key compounds responsible for the improved benefits. A total of 551 metabolites of PK extracts were identified, including polyphenols, flavonoids, alkaloids, and organic acids. During processing, 204 metabolites were enhanced, and 32 metabolites were recognized as key constituents of processed PK responsible for the improved health-promoting activities, which may affect PI3K-Akt-, MAPK-, and HIF-1 pathways. We further confirmed the high affinity between identified key constituents of processed PK and their predicted acting targets using molecular docking. CONCLUSION: Our results provide novel insights into bioactive compounds of processed PK, elaborating the rationality of processing from the perspective of tonic effects. Consuming processed PK could be an efficacious strategy to combat the high prevalence of metabolic diseases that currently affect millions of people worldwide. © 2023 Society of Chemical Industry.

The present study evaluated the effects of ginger and bitterleaf tea infusions on redox and inflammatory balance in rats. Twenty-four Wistar rats with weights of between 160 and 180 g were assigned into four (4) groups (n = 6). The control group received distilled water, while the remaining groups were administered tea infusions of ginger, bitterleaf, or a combination of both at 5 mg/mL, respectively. Bitterleaf and ginger teas elevated the levels of superoxide dismutase, catalase, glutathione peroxidase, and reduced glutathione in rat plasma and liver, while malondialdehyde levels decreased. Furthermore, ginger tea caused an increase in the expression of nuclear factor erythroid-2-related factor 2 (Nrf-2) and reduced tumor necrosis factor alpha (TNF-α). The GC-MS analysis of the teas identified 77 chemical compounds, among which gingerol and precocene I were predominant. Collectively, the findings indicate, in particular, that ginger tea may boost antioxidant and anti-inflammatory capacity by increasing Nrf-2 levels.
RESUMEN
BACKGROUND: Pickering emulsions stabilized by multicomponent particles have attracted increasing attention. Research on characterizing the digestion and health benefit effects of these emulsions in the human gastrointestinal tract are quite limited. This work aims to reveal the digestive characteristics of media-milled purple sweet potato particle-stabilized Pickering emulsions (PSPP-Es) during in vitro digestion and colonic fermentation. RESULTS: The media-milling process improved the in vitro digestibility and fermentability of PSPP-Es by reaching afree fatty acids release rate of 43.11 ± 4.61% after gastrointestinal digestion and total phenolic content release of 101.00 ± 1.44 µg gallic acid equivalents/mL after fermentation. In addition, PSPP-Es exhibited good antioxidative activity (2,2-diphenyl-1-picrylhydrazyl and ferric reducing antioxidant power assays), α-glucosidase inhibitory activity (half-maximal inhibitory concentration: 6.70%, v/v), and prebiotic effects, reaching a total short-chain fatty acids production of 9.90 ± 0.12 mol L-1, boosting the growth of Akkermansia, Bifidobacterium, and Blautia and inhibiting the growth of Escherichia-Shigella. CONCLUSIONS: These findings indicate that the media-milling process enhances the potential health benefits of purple sweet potato particle-stabilized Pickering emulsions, which is beneficial for their application as a bioactive component delivery system in food and pharmaceutical products. © 2024 Society of Chemical Industry.

BACKGROUND: Although knowledge of the barriers and motivators to physical activity participation among nurses is increasing, the factors influencing motivation methods' effectiveness are not completely defined. This study aimed to identify the methods that support increasing the level of daily physical activity and the factors that influence the effectiveness of motivation methods among nurses. METHODS: This study was based on an intervention study protocol. All registered nurses in clinical settings were invited to participate in the study. The study involved 71 professionally active nurses. A self-reported questionnaire was used to collect sociodemographic and employment data. The level of physical activity was assessed using the International Physical Activity Questionnaire, and the daily number of steps was assessed using a pedometer. Body composition was measured using a bioimpedance method, and the 5-year risk of cardiovascular events was assessed using the Harvard Score. The intervention included self-monitoring daily steps using a pedometer and completing a diary daily for one month. Additionally, a few-minute speech was sent to each participant via email on the intervention's 7th, 14th, and 21st days. RESULTS: The analysis revealed a higher value of physical activity recorded in the follow-up compared to the initial and final measurement in the Recreation domain [Met] (p < 0.001) and a higher value of daily steps in the follow-up compared to the final measurement (p = 0.005). Participants with a higher Harvard Score were more likely to increase their daily number of steps (OR = 6.025; 95% CI = 1.70-21.41), and nurses working in hospital wards were less likely to do so (OR = 0.002; 95% CI = 0.00-0.41). CONCLUSIONS: Recommendations for physical activity in the nursing population should focus on increasing leisure time physical activity and regular risk assessment of cardiovascular events. A mixed methods approach, such as feedback enhanced by health coaching, effectively achieves long-term physical activity changes in nurses.
RESUMEN
ISSUE ADDRESSED: Aboriginal and Torres Strait Islander Peoples' holistic concepts of wellbeing are inadequately represented in the health promotion discourse. The aim of this article was to explore what sustains an Aboriginal wellbeing program, to inform critical reflection and reorientation to empower Aboriginal wellbeing approaches in health promotion practice and policy. METHODS: Aboriginal and non-Indigenous researchers collaboratively designed a critically framed, strengths-based research approach with Aboriginal Community Controlled Health Service staff and wellbeing program participants. Data from Individual Yarning (n = 15) with program participants and staff inspired co-researchers to co-develop interpretations over two half-day Collaborative Yarning sessions (n = 9). RESULTS: Co-researchers depicted five lifeworld qualities that sustain an Aboriginal wellbeing program: love, connection, respect, culture and belonging. The lifeworld qualities are relational, communicative and involve the dynamics of identity, power and self-determination. CONCLUSIONS: The five qualities support a lifeworld approach to an Aboriginal wellbeing program, opening communicative and relational opportunities to mediate culturally responsive interactions. The qualities mediated interactions between people in the lifeworld including program participants and coordinators, and systems representatives including health service providers. A lifeworld approach provides a way to empower Aboriginal self-determination and leadership through embedment of cultural determinants of health in wellbeing programs. SO WHAT?: Health service providers and policy makers can use lifeworld approaches to guide critical reflection and reorient practice and policy related to Aboriginal health. The lifeworld qualities that encompass this approach in wellbeing programs are communicative and relational, centred on local community voices and co-produced with community for Aboriginal identity, empowerment and self-determination.

ISSUE: Universal school lunches hold the potential to improve student nutritional intake and access to food, but to do so menus must be nutritionally adequate. There is growing interest in school lunch programs (SLPs) in Australia, and one is currently being trialled in Tasmania. No nutrition guidelines currently exist for menu development in Australian schools. METHODS: A desktop review of international SLPs was completed, and findings analysed in the context of Australian Nutrient Reference Values and Australian Dietary Guidelines to inform the development of Tasmanian SLP guidelines. DISCUSSION: Globally, SLPs are guided by portion sizes and/or nutrient criteria. SLPs (many of which address food insecurity) must provide children the opportunity to meet energy and nutrient needs, while minimising food waste. We propose energy-based nutrient criteria and qualitative recommendations for menu development. SO WHAT?: We have developed guidelines to inform the development of Tasmanian SLP menus. These guidelines may be applicable to other states and territories piloting similar programs.
RESUMEN
ISSUE ADDRESSED: Canine Support Programs (CSPs) are a potential solution to growing university student support demands. While current studies focus on the impacts of CSPs, there is limited understanding of the views and expectations of tertiary students about CSPs. This study explored the perceptions and preferences of students in an Australian regional university about CSPs. METHODS: A questionnaire with multiple choice and open-ended questions surveyed residential students' perspectives about CSP. Data were analysed using descriptive statistical tests and thematic analysis for open responses. RESULTS: Majority (98%) of participants (sample n = 48) would support a CSP on campus. Frequent, small-group interactions of ≥15 min involving physical contact were preferred. Dog disposition, welfare-trained handlers, and veterinary certification were important aspects of program safety. Participants strongly agreed a CSP would improve mental health and well-being, relieve stress, reduce feelings of homesickness, provide support, comfort, and enable social interactions. CONCLUSION: There is strong support among the study population for CSP to be established on campus. This study supports earlier research that CSP has benefit potential for new, stressed, and/or students who love dogs. The preferences of students should inform program design to enhance utility and impact. This aligns with Health Promoting Universities and College's Okanagan Charter principle of 'engaging student voices'. More institutional awareness and support for CSPs will be necessary for integration. SO WHAT?: This study reveals the need for tailored and creative student support beyond traditional offerings including those that focus on student well-being and social initiatives. CSPs can be utilised as an advocate, enabler, and medium for mental health promotion action and well-being support for tertiary students; thereby, contributing to the 'Health Promoting University' agenda in Australia. It also reinforces the need for a Health in All Policies approach to be incorporated into our tertiary education sector. Future actions should focus on improving institutional awareness, support, and sector implementation.

Hepatocellular carcinoma (HCC) is an alarming epidemiological clinical problem worldwide. Pharmacological approaches currently available do not provide adequate responses due to poor effectiveness, high toxicity, and serious side effects. Our previous studies have shown that the wild edible plant Crithmum maritimum L. inhibits the growth of liver cancer cells and promotes liver cell differentiation by reducing lactic acid fermentation (Warburg effect). Here, we aimed to further characterise the effects of C. maritimum on lipid metabolism and markers of cellular metabolic health, such as AMP-activated protein kinase (AMPK), Sirtuin 1 (SIRT1), and Sirtuin 3 (SIRT3), as well as the insulin signalling pathway. To better mimic the biological spectrum of HCC, we employed four HCC cell lines with different degrees of tumorigenicity and lactic acid fermentation/Warburg phenotype. Lipid accumulation was assessed by Oil Red O (ORO) staining, while gene expression was measured by real-time quantitative PCR (RT-qPCR). The activation of AMPK and insulin signalling pathways was determined by Western blotting. Results indicate that C. maritimum prevents lipid accumulation, downregulates lipid and cholesterol biosynthesis, and modulates markers of metabolic health, such as AMPK, SIRT1 and SIRT3. This modulation is different amongst HCC cell lines, revealing an important functional versatility of C. maritimum. Taken together, our findings corroborate the importance of C. maritimum as a valuable nutraceutical, reinforcing its role for the improvement of metabolic health.

Tea flavonoids are widely recognized as critical flavor contributors and crucial health-promoting bioactive compounds, and have long been the focus of research worldwide in food science. The aim of this review paper is to summarize the major progress in tea flavonoid chemistry, their dynamics of constituents and concentrations during tea processing as well as storage, and their health functions studied between 2001 and 2021. Moreover, the utilization of tea flavonoids in the human body has also been discussed for a detailed understanding of their uptake, metabolism, and interaction with the gut microbiota. Many novel tea flavonoids have been identified, including novel A- and B-ring substituted flavan-3-ol derivatives, condensed and oxidized flavan-3-ol derivatives, and glycosylated and methylated flavonoids, and are found to be closely associated with the characteristic color, flavor, and health benefits of tea. Flavoalkaloids exist widely in various teas, particularly 8-C N-ethyl-2-pyrrolidinone-substituted flavan-3-ols. Tea flavonoids behave significantly difference in constituents and concentrations depending on tea cultivars, plantation conditions, multiple stresses, the tea-specified manufacturing steps, and even the long-term storage period. Tea flavonoids exhibit multiple health-promoting effects, particularly their anti-inflammatory in alleviating metabolic syndromes. Interaction of tea flavonoids with the gut microbiota plays vital roles in their health function.

Although bread is the main consumed staple food worldwide containing essential micro- and macronutrients, incorporation of probiotics (PRO) into this nondairy product has been less documented. Due to the mechanical and thermal stresses during bread-making process, production of PRO bread (PRO-BR) is dependent on development of emerging strategies like edible coating, encapsulation, three-dimensional printing, and application of thermophilic PRO strains. In the present study, novel technological and formulation aspects of PRO-BR, as well as critical conditions for obtaining products with guaranteed PRO potential have been reviewed. The biological functionality of these products, their scale up, marketing and commercial success factors are also highlighted. Production of functional PRO-BR containing bioactive compounds, phytochemicals and prebiotic components as an emerging field also affects dough rheology and textural features, sensory attributes and shelf-life of the final product. Recent data has revealed the effect of PRO on acrylamide content and staling rate of the produced bread. Furthermore, there are clinical evidences confirming the effects of PRO and synbiotic breads on reduction of triacylglycerol, low-density lipoprotein, insulin level and malondialdehyde, along with the increase of nitric oxide in the patients with type II diabetes.
