The Commercial Determinants of Men's Health Promotion: A Case Study of Gambling, Nonnies, and Athleisurewear.

Although the social determinants of health have guided equity work with the tailoring of men's health promotion programs, the role of, and potential for, the commercial determinants of health in those interventions is rarely addressed and poorly understood. While four commercial products, tobacco, alcohol, ultra-processed food, and fossil fuels, account for more than a third of global deaths, there is a need to recognize that consumer goods industries can make both positive and negative contributions to health. This article begins much-needed discussions about what we might learn from, and strategically tap in the commercial sector to seed, scale, and sustain men's health promotion programs. Three case studies, online sports betting, beer and the rise of the nonny, and athleisurewear, are discussed. Connections between online sports betting and masculinities explain young men's disproportionate involvement and gambling addictions with recommendations to legislate an end to gambling advertisements and de-incentivize industry profiteering through penalties and higher taxes. Regarding beer and the rise of the nonny, brewers have innovated with non-alcoholic beer based on shifting consumption patterns and masculinities in their core market-men. The nonny reminds health promoters to know their end-user's values and behaviors to bolster program acceptability. Detailing Under Armour and Lululemon, two highly gendered but diversifying athleisurewear brands, the complexities of, and potential for, leveraging public health and industry collaborations are underscored. Taken together, the article findings suggest men's health promoters should rigorously explore tapping key commercial entities and tax revenues to advance the health of men and their communities.

Sexual minority men's experiences of, and strategies for emotional intimacy in intimate partner relationships.

Emotional intimacy is key to intimate partner relationship quality and satisfaction. For sexual minority men, queer and feminist theorists consistently link emotional intimacy to diverse sexual practices and partnership dynamics formulated within the relationship. This Photovoice study adds to those insights by drawing on individual photovoice interviews with 16 sexual minority men to describe participant's experiences of, and strategies for emotional intimacy in their intimate relationships. Analysis revealed three distinct yet entwined themes: (i) embracing vulnerabilities to drive self-acceptance; (ii) building relationality with partners; and (iii) securing connections with family, friends and community. By embracing vulnerabilities to drive self-acceptance, participants spoke to embodied courage and autonomy as key components for addressing wide-ranging emotional intimacy challenges in their relationships. In theme two, building relationality with partners, participants described how empathy, trust and reciprocity underpinned collaborative work to foster emotional intimacy. Lastly, in securing connections with family, friends and community, acceptance and inclusion were key to participants' sense of belonging and legitimacy which aided their emotional intimacy with partners. The findings provide guidance for tailored programmatic efforts to assist sexual minority men build intimate relationships.

Promoting men's health through sports clubs: A systematic rapid realist review.

BACKGROUND: Health promotion (HP) interventions delivered through sports clubs have demonstrated promising outcomes among men, but less is known about which aspects of the interventions work, for whom, and under what circumstances. This rapid realist review aims to understand the contexts, mechanisms, and outcomes of HP interventions for men delivered through sports clubs. METHODS: A systematic literature search was conducted in February 2023 for studies published after 2013 in MEDLINE, Embase, and SPORTDiscus databases. INCLUDED STUDIES: (a) were delivered by or in collaboration with sports clubs, (b) targeted men aged 18+ years, and (c) reported 1 or more HP outcome. A grey literature search was also performed. Studies were included in a realist synthesis based on richness and rigor. Hereafter, context-mechanisms-outcome (CMO) configurations were developed. RESULTS: We identified and screened 3356 studies, finally including 60 studies describing 22 interventions. Most HP interventions were delivered in high income countries, included Caucasian men aged 35-65 years with overweight/obesity, and used professional sports clubs (mostly football) for recruitment and facilities. Quantitative HP outcomes were reported across 19 interventions. Of these 19 interventions, the majority reported on weight (n = 18), physical activity (n = 12), mental health (n = 10), and diet (n = 9). We identified 12 CMOs related to how HP interventions affected men's recruitment, engagement, and health behavior maintenance. CONCLUSION: Our findings show that using sports clubs for HP interventions is effective for engaging men. Recruitment was facilitated by leveraging sports clubs' identity, addressing masculinity-related barriers, improving accessibility, and building trust. Engagement was enhanced through shared identity experiences, safe spaces, inclusive competition, and self-efficacy. However, there's limited evidence on behavior maintenance post-intervention, though involving community stakeholders seemed vital. In general, considerations should be made to avoid perpetuating traditional masculine norms, which may exclude some men and reinforce unhealthy behaviors. These findings can guide intervention development, emphasizing the need to harness men's perspectives in the process.

Humans adaptively deploy forward and backward prediction.

The formation of predictions is essential to our ability to build models of the world and use them for intelligent decision-making. Here we challenge the dominant assumption that humans form only forward predictions, which specify what future events are likely to follow a given present event. We demonstrate that in some environments, it is more efficient to use backward prediction, which specifies what present events are likely to precede a given future event. This is particularly the case in diverging environments, where possible future events outnumber possible present events. Correspondingly, in six preregistered experiments (n = 1,299) involving both simple decision-making and more challenging planning tasks, we find that humans engage in backward prediction in divergent environments and use forward prediction in convergent environments. We thus establish that humans adaptively deploy forward and backward prediction in the service of efficient decision-making.

Origin of the human malaria parasite Plasmodium vivax.

The geographic origin of Plasmodium vivax, a leading cause of human malaria, has been the subject of much speculation. Here we review the evolutionary history of P. vivax and P. vivax-like parasites in humans and non-human primates on three continents, providing overwhelming evidence for an African origin. This conclusion is consistent with recent reports showing that Duffy-negative humans in Africa are, in fact, susceptible to P. vivax, with parasites invading Duffy-antigen-expressing erythroid precursors. Thus, the African origin of P. vivax not only explains the distribution of the Duffy-negative genotype but also provides new insight into the history and status of P. vivax malaria in Africa and efforts geared toward its eradication.

Men's peer support for mental health challenges: future directions for research and practice.

Peer support has a long history of helping people navigate mental health challenges and is increasingly utilized within men's mental health promotion initiatives. Despite considerable research conceptualizing and evaluating peer support in various contexts, little is known about the gendered dimensions of men's peer support and mutual help for mental health. This article provides an empirically informed commentary on men's peer support and informal help-seeking preferences to make recommendations for future directions for research and practice. Research examining men's peer support is emergent and the available evidence suggests that there is potential to conceptually align with many men's values and preferences for mental health help-seeking. Peer support offers a non-clinical, strength-based adjunct to professional support that may aid men in navigating a range of mental health challenges. Consideration must be given to the influence of gender socialization and men's diverse experiences with developing and maintaining peer relationships. It should not be assumed that authentic and supportive relationships will naturally form when men congregate together. As a growing number of interventions and programs emerge targeted at boys and men, there are important opportunities to leverage these health promotion efforts to encourage and coach men to engage in mutual help. Opportunities for research and practice are discussed to better understand and harness the health-promoting potential of peer support for men's mental health.

Masculinity, Meat, and Veg*nism: A Scoping Review.

Men historically consume more meat than women, show fewer intentions to reduce meat consumption, and are underrepresented among vegans and vegetarians. Eating meat strongly aligns with normative masculinities, decisively affirming that "real men" eat meat and subordinating men who choose to be veg*n (vegan or vegetarian). The emergence of meat alternatives and increasing environmental concerns may contest these long-standing masculine norms and hierarchies. The current scoping review addresses the research question what are the connections between masculinities and men's attitudes and behaviors toward meat consumption and veg*nism? Using keywords derived from two key concepts, "men" and "meat," 39 articles were selected and analyzed to inductively derive three thematic findings; (a) Meat as Masculine, (b) Veg*n Men as Othered, and (c) Veg*nism as Contemporary Masculinity. Meat as Masculine included how men's gendered identities, defenses, and physicalities were entwined with meat consumption. Veg*n Men as Othered explored the social and cultural challenges faced by men who adopt meatless diets, including perceptions of emasculation. Veg*nism as Contemporary Masculinity was claimed by men who eschewed meat in their diets and advocated for veg*nism as legitimate masculine capital through linkages to physical strength, rationality, self-determination, courage, and discipline. In light of the growing concern about the ecological impact of meat production and the adverse health outcomes associated with its excessive consumption, this review summarizes empirical connections between masculinities and the consumption of meat to consider directions for future men's health promotion research, policy, and practice.

Wild edible yams from Madagascar: New insights into nutritional composition support their use for food security and conservation.

Yams (Dioscorea species) are an important food resource in Madagascar, where both cultivated winged yam (D. alata) and wild edible yams are consumed. However, there is limited knowledge on the nutrient composition of wild edible yams in Madagascar, and on how they compare with the cultivated winged yam. Therefore, in this study, nine wild edible yam species, one with two subspecies from Madagascar (D. bako, D. buckleyana, D. irodensis, D. maciba, D. orangeana, D. pteropoda, D. sambiranensis subsp. bardotiae and subsp. sambiranensis, D. seriflora, and Dioscorea species Ovy valiha), were analyzed for their nutrient composition, compared with cultivated D. alata. They include 6/6 of the most favored wild edible yam species in Madagascar. New nutrient composition data (protein, carbohydrate/starch, energy, lipid, ß-carotene, and minerals) are presented for these nine wild edible yam species. The results show that they contain comparable levels of lipids and starch to D. alata, but none are better sources of protein than D. alata. The results show that D. irodensis contains a significantly higher ß-carotene content when compared to all other edible yams analyzed, and that D. buckleyana, D. irodensis, and D. sambiranensis subsp. bardotiae have a higher calcium content than cultivated D. alata, while all nine wild edible yam species analyzed contain a higher iron content, compared to cultivated D. alata. The nutrient composition data presented could provide new incentives to conserve wild edible yams and inform on strategies to select Dioscorea species for sustainable cultivation and use, providing opportunities to enhance future food security in Madagascar.

The two parasite species formerly known as Plasmodium ovale.

Plasmodium ovale was the last of the exclusively human malaria parasites to be described, in 1922, and has remained the least well studied. Beginning in 1995, two divergent forms of the parasite, later termed 'classic' and 'variant', were described. By 2010, it was realised that these forms are two closely related, but genetically distinct and non-recombining species; they were given the names Plasmodium ovale curtisi and Plasmodium ovale wallikeri. Since then, substantial additional data have confirmed that the two parasites are indeed separate species, but the trinomial nomenclature has often led to confusion about their status, with many authors describing them as subspecies. We hereby formally name them Plasmodium ovalecurtisi and Plasmodium ovalewallikeri.

"Hey Amir, How Are You REALLY Doing?": Participant Perspectives of a Peer-Based Suicide Prevention Campaign for Men.

Suicide is a major public health concern and leading cause of death among men in Canada. This study reports the feasibility and acceptability of Buddy Up, a peer-based suicide prevention campaign for men. A mixed-methods approach was used to analyze respondent survey questionnaires (n = 48) and individual participant interviews (n = 19) collected from campaign users. Survey respondents reported that they enjoyed their involvement in the campaign (92%), were more confident to talk with men about mental health and suicide (95%), and would recommend Buddy Up to others (95%). Qualitative interviews were thematically analyzed to develop three inductively derived themes: (a) Engaging men with relatable masculine content and design: "Buddy Up really spoke to them in their language," highlighting the importance of understanding and working with gendered practices and motivations to legitimize and motivate involvement in suicide prevention; (b) Leveraging campaign participation to initiate conversations and promote mental health: "It gives men language and license to start asking questions," revealing ways in which participants utilized Buddy Up to negotiate and norm checking-in to promote men's mental health; and (c) Driving new masculine cultures: "We start every meeting with a mental health moment," identifying how participants fostered healthy milieus for disclosing mental health challenges with teamwork and preventive action under the banner of Buddy Up. The study findings support the feasibility of Buddy Up and highlight the acceptability of peer-based approaches to mental health promotion. The findings can also empirically guide future efforts for systematically building men's peer-based suicide prevention programs.

Exploring the practicality and acceptability a brief exercise communication and clinician referral pathway in cancer care: a feasibility study.

BACKGROUND: The majority of cancer patients and cancer care clinicians-CCCs (e.g., oncologists) believe that exercise is an important adjunct therapy that should be embedded in standard practice. Yet, CCCs do not routinely discuss exercise with their patients, nor do they regularly refer them to exercise professionals (e.g., exercise physiologists-EPs). This study evaluated the feasibility and acceptability of an evidence-based approach to improving exercise communication between CCCs and their patients, including an exercise referral pathway. METHODS: Implementation and testing of the Exercise Communication and Referral Pathway (ECRP) occurred in Sydney, Australia. The ECRP included a brief oncology-initiated communication exchange with patients, CCC exercise referral to an EP, followed by EP-initiated telephone consultation with patients concerning tailored exercise advice. Participant perceptions concerning the feasibility and applicability of the ECPR were evaluated. Semi-structured interviews were conducted with CCCs (n = 3), cancer patients (n = 21), and an EP (n = 1). Inductive thematic analysis was undertaken. RESULTS: Analysis generated three themes: (1) Navigating the role of CCCs in the ECRP, suggesting that oncology-initiated communication is a cue to action, however there was a lack of role clarity regarding exercise referral; (2) Implementing Patient-Orientated Care within a Standardised Pathway, highlighting the need for tailored information and advice for patients that reflects individual disease, socio-cultural, and environmental factors, and; (3) Taking Steps Towards Action, revealing the need for structural (e.g., EP initiated contact with patients) and policy changes (i.e., changes to Medicare, direct oncologist referral) to engage patients and better integrate exercise as part of standard care. CONCLUSIONS: Findings provide important insights into improving oncology-patient exercise communication and developing an exercise referral pathway to increase engagement and patient reach. However, individual (e.g., experience, knowledge) and contextual factors (e.g., time, resources) need consideration when implementing an ECRP. TRIAL REGISTRATION: This trial was prospectively registered with the Australian New Zealand Clinical (#ACTRN12620000358943) on March 13, 2020.

Ferulic acid protects HepG2 cells and mouse liver from iron-induced damage.

Liver as iron storage organ is particularly susceptible to oxidative stress-induced injury from excess iron. Thus, antioxidant therapies are often used to reverse oxidative damage and protect cells and tissues. This study investigated the protective effects of phenolic acids; ferulic acid (FA) and its metabolite, ferulic acid 4-O-sulfate disodium salt (FAS) against oxidative stress under iron overload conditions in mouse and HepG2 cells. Cells were exposed to FA or FAS and then treated with iron-induced oxidative stress complex of 50 µmol/L FAC and 20 µmol/L of 8-hydroxyquinoline 8HQ (8HQ-FAC). Iron dextran was injected intraperitoneally on alternate days for 10 days to induce the iron overload condition in BALB/c mice. The study revealed that the phenolic acids were protective against ROS production, lipid peroxidation and antioxidant depletion in HepG2 cells and liver tissues of BALB/c mice during iron-induced oxidative stress. The protective function of phenolic acids was achieved by the transcriptional activation of nuclear factor erythroid-2-related factor 2 (Nrf2) to regulate antioxidant genes. In conclusion, the study provides evidence that FA has the potential as a therapeutic agent against iron-related diseases such as T2D.

"A feeling for run and rhythm": coaches' perspectives of performance, talent, and progression in rowing.

The understanding of rowing performance has been predominantly gained through quantitative sports science-based research. In combination with this objective information, coaches' experiences may provide important contextual information for how this quantitative evidence is implemented into training programmes. The aims of this study were to (1) explore coaches' perspectives of performance indicators for competitive rowing in junior rowers, and (2) identify coaches' recommendations for developing effective technique and movement competency among junior rowers who have the potential to transition to elite competition. Twenty-seven semi-structured interviews were conducted with experienced rowing coaches through purposive sampling of an accredited coaching network. Participants' coaching experience ranged from 5 to 46 (M = 22, SD = 10) years. Data were analysed using thematic analysis. Three overarching themes were identified including, (1) getting the basics right, (2) targeting types of talent, and (3) complexities of performance. Based on these findings, sequence and boat feel, supported through the movement competency provided by hip flexibility and the trunk musculature, were considered critical for executing correct technique. Developing talent and understanding successful performance are both complex concepts when considering the individual athlete. Coaches' perspectives provided insight into key components of performance to enhance our understanding of how to better develop junior rowers.

Unusually Divergent Ubiquitin Genes and Proteins in Plasmodium Species.

Ubiquitin is an extraordinarily highly conserved 76 amino acid protein encoded by three different types of gene, where the primary translation products are fusions either of ubiquitin with one of two ribosomal proteins (RPs) or of multiple ubiquitin monomers from head to tail. Here, we investigate the evolution of ubiquitin genes in mammalian malaria parasites (Plasmodium species). The ubiquitin encoded by the RPS27a fusion gene is highly divergent, as previously found in a variety of protists. However, we also find that two other forms of divergent ubiquitin sequence, each previously thought to be extremely rare, have arisen recently during the divergence of Plasmodium subgenera. On two occasions, in two distinct lineages, the ubiquitin encoded by the RPL40 fusion gene has rapidly diverged. In addition, in one of these lineages, the polyubiquitin genes have undergone a single codon insertion, previously considered a unique feature of Rhizaria. There has been disagreement whether the multiple ubiquitin coding repeats within a genome exhibit concerted evolution or undergo a birth-and-death process; the Plasmodium ubiquitin genes show clear signs of concerted evolution, including the spread of this codon insertion to multiple repeats within the polyubiquitin gene.

Strategies to increase the bioaccessibility and bioavailability of iron and zinc from cereal products.

Cereal products provide 50 % of iron and 30 % of zinc in the UK diet. However, despite having high content, the bioavailability of minerals from cereals is low. This review discusses strategies to increase mineral bioavailability from cereal-based foods. Iron and zinc are localised to specific tissue structures within cereals; however, the cell walls of these structures are resistant to digestion in the human gastrointestinal tract and therefore the bioaccessibility of these essential minerals from foods for absorption in the intestine is limited. In addition, minerals are stored in cereals bound to phytate, which is the main dietary inhibitor of mineral absorption. Recent research has focused on ways to enhance mineral bioavailability from cereals. Current strategies include disruption of plant cell walls to increase mineral release (bioaccessibility) during digestion; increasing the mineral:phytate ratio either by increasing the mineral content through conventional breeding and/or agronomic biofortification, or by reducing phytate levels; and genetic biofortification to increase the mineral content in the starchy endosperm, which is used to produce white wheat flour. While much of this work is at an early stage, there is potential for these strategies to lead to the development of cereal-based foods with enhanced nutritional qualities that could address the low mineral status in the UK and globally.

Working with men in the context of distressed and disrupted intimate partner relationships: A qualitative study.

OBJECTIVE: To describe key considerations for working with men experiencing distressed and disrupted intimate partner relationships. METHODS: Individual Zoom interviews were conducted with help-seeking men (n = 25) who had experienced an intimate partnership break-up, and health service providers (n = 30) working with men in the relationships space. Interpretive Description methodology was used to generate considerations for working with men in distressed and disrupted relationships. RESULTS: Three thematic findings were inductively derived; 1) A whole life approach for deconstructing relationships, wherein men engaged in discussions about their broader experiences and circumstances within the context of intimate partnerships; 2) Affirming men's relationship emotions and vulnerabilities as normative and changeable, comprising coaching for embodying transformative masculinities; and 3) Tangible 'to do's' in and after a relationship, outlining men's present and prospective self-work with action-oriented strategies. CONCLUSION: Strategies tailored to men's receptivity and needs can increase connection with professional services and providers to bolster the mental health of men in and after disrupted intimate partner relationships. PRACTICE IMPLICATIONS: With men increasingly accessing professional mental health services, the present study offers key considerations and recommendations regarding assessment, communication, and treatment for health service providers working with men in the relationships space.

Disrupted state transition learning as a computational marker of compulsivity.

BACKGROUND: Disorders involving compulsivity, fear, and anxiety are linked to beliefs that the world is less predictable. We lack a mechanistic explanation for how such beliefs arise. Here, we test a hypothesis that in people with compulsivity, fear, and anxiety, learning a probabilistic mapping between actions and environmental states is compromised. METHODS: In Study 1 (n = 174), we designed a novel online task that isolated state transition learning from other facets of learning and planning. To determine whether this impairment is due to learning that is too fast or too slow, we estimated state transition learning rates by fitting computational models to two independent datasets, which tested learning in environments in which state transitions were either stable (Study 2: n = 1413) or changing (Study 3: n = 192). RESULTS: Study 1 established that individuals with higher levels of compulsivity are more likely to demonstrate an impairment in state transition learning. Preliminary evidence here linked this impairment to a common factor comprising compulsivity and fear. Studies 2 and 3 showed that compulsivity is associated with learning that is too fast when it should be slow (i.e. when state transition are stable) and too slow when it should be fast (i.e. when state transitions change). CONCLUSIONS: Together, these findings indicate that compulsivity is associated with a dysregulation of state transition learning, wherein the rate of learning is not well adapted to the task environment. Thus, dysregulated state transition learning might provide a key target for therapeutic intervention in compulsivity.

Content and Availability of Minerals in Plant-Based Burgers Compared with a Meat Burger.

Increasing numbers of individuals follow plant-based diets. This has sparked interest in the nutritional evaluation of the meat substitute sector. Nutritional understanding of these products is vital as plant-based eating becomes more common. For example, animal products are rich sources of iron and zinc, and plant-based foods could be inadequate in these minerals. The main aim was to analyse the mineral composition and absorption from a range of plant-based meat-free burgers and compare them to a typical beef burger. Total and bioaccessible mineral contents of plant-based burgers and a beef burger were determined using microwave digestion and in vitro simulated gastrointestinal digestion, respectively. Mineral bioavailability was analysed by in vitro simulated gastrointestinal digestion of foods, followed by exposure of Caco-2 cells to the sample digests and assessment of mineral uptake. Mineral quantification for all samples was achieved using inductively coupled ICP-optical emission spectrometry (ICP-OES). The content of minerals varied significantly amongst the burgers. Significantly greater quantities of Fe and Zn were found in the beef burger compared to most meat substitutes. Bioaccessible Fe was significantly higher in the beef compared to most of the plant-based meat alternatives; however, bioavailable Fe of most plant-based burgers was comparable to beef (p > 0.05). Similarly, bioaccessible Zn was significantly (p < 0.001) higher from the beef burger. Moreover, beef was superior regarding bioavailable Zn (p ≤ 0.05-0.0001), with only the mycoprotein burger displaying comparable Zn bioavailability (p > 0.05). Beef is an excellent source of bioaccessible Fe and Zn compared to most plant-based substitutes; however, these plant-based substitutes were superior sources of Ca, Cu, Mg and Mn. The quantity of bioaccessible and absorbable Fe varies dramatically among the meat alternatives. Plant-based burgers have the potential to provide adequate quantities of iron and zinc to those consuming such burgers as part of a varied diet. Thus, guiding consumer choices will depend on the variety of the vegetable constituents and their iron nutritional quality in different burgers.
