Sustainable and Eco-Friendly DLC Fabrication for Replacing Chrome on a Gravure Cylinder Surface.

This paper evaluates the potential of diamond-like carbon (DLC) as a durable surface protection to replace the chromium (Cr) layer, which is traditionally applied to gravure print cylinders and other components through a galvanic electroplating process. The fabrication of DLC is more eco-friendly and could reduce the environmental hazard posed by hexavalent chromium in liquid form that is used in Cr application and better adhere to environmental regulations. This could encourage businesses to bring the DLC fabrication process in-house, sharing resources such as materials, labor, and equipment, to help reduce costs. Four DLC variants (standard DLC, A-DLC, S-DLC, and organic silica) and chrome were analyzed and tested for their surface properties and durability. Data suggest that both standard DLC and S-DLC had higher surface free energy, allowing for good ink wetting on the surface when compared to chrome. In addition, the standard DLC and S-DLC surfaces are generally smoother than the chrome, resulting in lower relative hydrophilicity and allowing for easier removal of ink in the nonimage regions with the doctor blade. The elcometer adhesion test demonstrated that the bond strength of the DLC variants to their base layer was comparable to the bond strength of chrome, indicating that the adhesion strength of the two materials was similar. Furthermore, in the abrasion test, the wear on the standard DLC surface and the corresponding wear on the lamella tip of the metal doctor blades were notably lower than that observed on chrome. This distinction is particularly evident in each of the test trials, specifically run 1, which involved 2,000,000 wiping actions of a metal doctor blade in the presence of abrasive TiO2 ink pigments. Statistical analysis on standard DLC versus chrome suggests that DLC fabrication is effective and durable on plain and patterned surfaces. Therefore, from a sustainable and eco-friendly perspective, standard DLC and S-DLC would be good alternative durable surfaces for print cylinders and other components used in various industries due to superior wear resistance properties.

Whole-body hypothermia in mild neonatal encephalopathy: protocol for a multicentre phase III randomised controlled trial.

BACKGROUND: Mild hypoxic ischemic encephalopathy is associated with sub optimal cognition and learning difficulties at school age. Although whole-body hypothermia reduces death and disability after moderate or severe encephalopathy in high-income countries, the safety and efficacy of hypothermia in mild encephalopathy is not known. The cooling in mild encephalopathy (COMET) trial will examine if whole-body hypothermia improves cognitive development of neonates with mild encephalopathy. METHODS: The COMET trial is a phase III multicentre open label two-arm randomised controlled trial with masked outcome assessments. A total of 426 neonates with mild encephalopathy will be recruited from 50 to 60 NHS hospitals over 2 ½ years following parental consent. The neonates will be randomised to 72 h of whole-body hypothermia (33.5 ± 0.5 C) or normothermia (37.0 ± 0.5 C) within six hours or age. Prior to the recruitment front line clinical staff will be trained and certified on expanded modified Sarnat staging for encephalopathy. The neurological assessment of all screened and recruited cases will be video recorded and centrally assessed for quality assurance. If recruitment occurs at a non-cooling centre, neonates in both arms will be transferred to a cooling centre for continued care, after randomisation. All neonates will have continuous amplitude integrated electroencephalography (aEEG) at least for the first 48 h to monitor for seizures. Predefined safety outcomes will be documented, and data collected to assess resource utilization of health care. A central team masked to trial group allocation will assess neurodevelopmental outcomes at 2 years of age. The primary outcome is mean difference in composite cognitive scores on Bayley scales of Infant and Toddler development 4th Edition. DISCUSSION: The COMET trial will establish the safety and efficacy of whole-body hypothermia for mild hypoxic ischaemic encephalopathy and inform national and international guidelines in high income countries. It will also provide an economic assessment of whole-body hypothermia therapy for mild encephalopathy in the NHS on cost-effectiveness grounds. TRIAL REGISTRATION NUMBER: NCT05889507 June 5, 2023.

Police Violence: Reducing the Harms of Policing Through Public Health-Informed Alternative Response Programs.

Police violence is a public health issue in need of public health solutions. Reducing police contact through public health-informed alternative response programs separate from law enforcement agencies is one strategy to reduce police perpetration of physical, emotional, and sexual violence. Such programs may improve health outcomes, especially for communities that are disproportionately harmed by the police, such as Black, Latino/a, Native American, and transgender communities; nonbinary residents; people who are drug users, sex workers, or houseless; and people who experience mental health challenges. The use of alternative response teams is increasing across the United States. This article provides a public health rationale and framework for developing and implementing alternative response programs informed by public health principles of care, equity, and prevention. We conclude with recommendations for public health researchers and practitioners to guide inquiries into policing as a public health problem and expand the use of public health-informed alternative response programs.

Antiracism and Community-Based Participatory Research: Synergies, Challenges, and Opportunities.

Structural racism causes stark health inequities and operates at every level of society, including the academic and governmental entities that support health research and practice. We argue that health research institutions must invest in research that actively disrupts racial hierarchies, with leadership from racially marginalized communities and scholars. We highlight synergies between antiracist principles and community-based participatory research (CBPR), examine the potential for CBPR to promote antiracist research and praxis, illustrate structural barriers to antiracist CBPR praxis, and offer examples of CBPR actions taken to disrupt structural racism. We make recommendations for the next generation of antiracist CBPR, including modify health research funding to center the priorities of racially marginalized communities, support sustained commitments and accountability to those communities by funders and research institutions, distribute research funds equitably across community and academic institutions, amplify antiracist praxis through translation of research to policy, and adopt institutional practices that support reflection and adaptation of CBPR to align with emergent community priorities and antiracist practices. A critical application of CBPR principles offers pathways to transforming institutional practices that reproduce and reinforce racial inequities.

Associations of attitudes and social norms with experiences of intimate partner violence among married adolescents and their husbands in rural Niger: a dyadic cross-sectional study.

BACKGROUND: Prior cross-sectional research suggests that both men's and women's attitudes towards intimate partner violence (IPV) are predictive of women's IPV experience, although this can vary greatly by context. In general, women who have experienced IPV are likely to report attitudes accepting of it. Men who perpetrate IPV may also report attitudes accepting of it, although some research has found that there is not always an association. Studies that investigate these dynamics often conflate attitudes with social norms, or use attitudes as a proxy for social norms, given that valid measures on social norms are usually lacking. Here we conduct a secondary data analysis to ask how are men's and women's IPV-related attitudes associated with women's reports of IPV and how are men's and women's perceived social norms associated with women's reports of IPV. METHODS: Dyadic data were collected from a representative sample of married adolescent girls and their husbands in 48 rural villages of the Dosso region of Niger (N = 1010). Assessments included logistic regression analyses of husbands' and wives' reports of individual attitudes towards IPV, and social norms based on husbands' and wives' perceptions of their communities' beliefs related to gender roles and acceptability of IPV. RESULTS: Eight percent of women in this sample reported IPV. We found that, consistent with other research, wives who have reported IPV are more likely to report attitudes in support of IPV, while for husbands whose wives report IPV, that relationship is insignificant. On the other hand, husbands who report that people in their community believe there are times when a woman deserves to be beaten are more likely to have perpetrated IPV, while for wives there is no association between the community norm and IPV reporting. Finally, wives who report that people in their community hold inequitable gender norms in general are more likely to have experienced IPV, while for husbands, community gender norms are not predictive of whether their wives have reported IPV. CONCLUSIONS: Our results are evidence that IPV prevention interventions focused solely on individual attitudes may be insufficient. Targeting and assessment of social norms are likely critical to advancing understanding and prevention of IPV.

Paediatric research in the times of COVID-19.

The COVID-19 pandemic poses many direct and indirect consequences for children's health and associated research. Direct consequences include participation of children in COVID-19 research trials, pausing other research in children and the potential implications of a global economic downturn on future research funding. Collaborative and networked research together with streamlined research processes and use of remote technology have been central to efforts by clinicians and scientists around the world and have proved essential for reducing COVID-19 morbidity and mortality. IMPACT: Maintain streamlined and efficient approaches to research governance and data sharing to facilitate high-quality collaborative research. Ensure early inclusion of children in trials of therapies for diseases that affect all age groups. Paediatric Research Societies should co-ordinate effective processes to define key research questions and develop multinational clinical trials for diagnostics, therapeutics and preventative strategies for infants, children and young people.

Bifidobacterium breve BBG-001 and intestinal barrier function in preterm babies: Exploratory Studies from the PiPS Trial.

BACKGROUND: Uncertainty remains about the role of probiotics to prevent necrotising enterocolitis (NEC) some of which arises from the variety of probiotic interventions used in different trials, many with no prior evidence of potential efficacy. Mechanistic studies of intestinal barrier function embedded in a large probiotic trial could provide evidence about which properties of probiotics might be important for NEC prevention thus facilitating identification of strains with therapeutic potential. METHODS: Intestinal permeability, stool microbiota, SCFAs and mucosal inflammation were assessed from the second postnatal week in babies enrolled to a randomised controlled trial of B. breve BBG-001 (the PiPS trial). Results were compared by allocation and by stool colonisation with the probiotic. RESULTS: Ninety-four preterm babies were recruited across six nested studies. B. breve BBG-001 content was higher by allocation and colonisation; Enterobacteriaceae and acetic acid levels were higher by colonisation. No measure of intestinal barrier function showed differences. The PiPS trial found no evidence of efficacy to reduce NEC. CONCLUSIONS: That the negative results of the PiPS trial were associated with failure of this probiotic to modify intestinal barrier function supports the possibility that the tests described here have the potential to identify strains to progress to large clinical trials. IMPACT: Uncertainty about the therapeutic role of probiotics to prevent necrotising enterocolitis is in part due to the wide range of bacterial strains with no previous evidence of efficacy used in clinical trials. We hypothesised that mechanistic studies embedded in a probiotic trial would provide evidence about which properties of probiotics might be important for NEC prevention. The finding that the probiotic strain tested, Bifidobacterium breve BBG-001, showed neither effects on intestinal barrier function nor clinical efficacy supports the possibility that these tests have the potential to identify strains to progress to large clinical trials.

Integration of voluntary male medical circumcision for HIV prevention into norms of masculinity: findings from Kisumu, Kenya.

While it is clear that in many communities ideas about masculinity and circumcision are connected, it is still unclear how young Kenyan men in the former Nyanza province from the traditionally non-circumcising Luo people perceive voluntary medical male circumcision as connected to masculinity and the role of voluntary medical male circumcision in the transition from boyhood to manhood. The objective of this study was to explore norms of masculinity and the decision-making process among Luo young men to provide a better understanding of how circumcision and masculinity relate to cultural norms within this community. The methodology consisted of eight FGDs with male peer groups and 24 in-depth interviews to elicit young men's perceptions of masculinity and voluntary medical male circumcision. Findings from thematic analysis reveal that young men described several key characteristics of masculinity including responsibility, bravery and sexual attractiveness. For some young men, voluntary medical male circumcision has embedded itself into cultural norms of masculinity by being a step in the transition from boyhood to manhood and by being a marker of some of these masculine characteristics. In the case of voluntary medical male circumcision, there may be opportunities to integrate other programming that helps men transition into healthy adulthood.

Factors associated with reproductive autonomy in Ghana.

Reproductive autonomy is essential for women to achieve reproductive rights and freedom. However, the factors associated with reproductive autonomy in various contexts have not been explored. The aim of this analysis was to understand the socio-demographic, reproductive history and social context variables associated with two validated reproductive autonomy sub-scales among 516 young Ghanaian women age 15 to 24. We used multiple linear regression modelling to test associations between covariates of interest and the communication sub-scale and decision-making sub-scale. Covariates included age, educational attainment, ethnic group, employment, religion, religious attendance, relationship type, previous pregnancy, previous abortion, social support for adolescent sexual and reproductive health, and social stigma towards adolescent sexual and reproductive health. Results from final models demonstrated that factors associated with the communication scale included education (p = 0.008), ethnic group (p = 0.039), and social support for adolescent sexual and reproductive health (B = 0.12, p = 0.003). Factors associated with the decision-making scale included ethnic group (p = 0.002), religion (p = 0.003), religious attendance (p = 0.043), and previous pregnancy (p = 0.008). Communication reproductive autonomy and decision-making reproductive autonomy were associated with different factors, providing insight into potential intervention approaches and points. Social support for adolescent sexual and reproductive health was associated with increases in young women's abilities to communicate with their partners about sexual and reproductive health issues including sex, contraceptive use and fertility.

Adolescent Risk of Dating Violence and Electronic Dating Abuse: A Latent Class Analysis.

Electronic forms of dating violence among youth are common yet little is known about how these forms of violence overlap with the commonly studied domains of physical, sexual and verbal teen dating violence. Using factor analysis and latent class analysis, this study identifies patterns of electronic, verbal, physical and sexual dating violence victimization and perpetration in 9th and 12th graders. Data are from 470 9th (n = 190; 60.5% female; mean age = 12.0 years, age range: 11.3-13.8) and 12th graders (n = 280; 63.9% female; mean age = 14.9 years, age range: 14.0-16.6) from southeastern Michigan. A 5-class solution for 9th graders and a 6-class solution for 12th graders were selected given fit and interpretability. Classes were characterized by domain(s) of violence, as opposed to perpetration or victimization. Three domains of electronic dating aggression were identified: monitoring, harassment, and coercion. Electronic dating aggression was present in the majority of classes, and overlapped substantially with other domains of violence. The highest risk class had risk of victimization and perpetration for all types of dating violence (electronic monitoring, electronic harassment, electronic coercion, verbal violence, physical violence and sexual violence). Drug use and experiencing one or more adverse childhood experiences predicted membership in a higher risk group for the older cohort, while alcohol consumption predicted higher risk for the younger cohort. The findings from this study show overlap between dating violence domains and imply that domains of electronic dating violence are important to consider in conjunction with physical, sexual and verbal domains, to address teen dating violence.

Spatial analysis of individual- and village-level sociodemographic characteristics associated with age at marriage among married adolescents in rural Niger.

BACKGROUND: Niger has the highest prevalence of child marriage in the world. While child marriage in Niger is clearly normative in the sense that it is commonly practiced, the social and contextual factors that contribute to it are still unclear. METHODS: Here, we tested the importance of village-level factors as predictors of young age at marriage for a group of married adolescent girls (N = 1031) in the Dosso district of rural Niger, using multi-level and geographic analyses. We aggregated significant individual level factors to determine whether, independent of a girl's own sociodemographic characteristics, the impact of each factor is associated at the village level. Finally, we tested for spatial dependence and heterogeneity in examining whether the village-level associations we find with age at marriage differ geographically. RESULTS: The mean age of marriage for girls in our study was 14.20 years (SD 1.8). Our statistical results are consistent with other literature suggesting that education is associated with delayed marriage, even among adolescent girls. Younger ages at marriage are also associated with a greater age difference between spouses and with a greater likelihood of women being engaged in agricultural work. Consistent with results at the individual level, at the village level we found that the proportion of girls who do agricultural work and the mean age difference between spouses were both predictive of a lower age at marriage for individual girls. Finally, mapping age at marriage at the village level revealed that there is geographical variation in age at marriage, with a cluster of hot spots in the Hausa-dominated eastern area where age at marriage is particularly low and a cluster of cold spots in the Zarma-dominated western areas where age at marriage is relatively high. CONCLUSIONS: Our findings suggest that large-scale approaches to eliminating child marriage in these communities may be less successful if they do not take into consideration geographically and socially determined contextual factors at the village level.

Application of the Minority Stress Theory: Understanding the Mental Health of Undocumented Latinx Immigrants.

This paper applies the Minority Stress framework to data collected from an ongoing community-based participatory research project with health and social service agencies in Southeast Michigan. We examine the stressors and coping strategies employed by undocumented Latinx immigrants and their families to manage immigration-related stress. We conducted in-depth interviews with 23 immigrant clients at Federally Qualified Health Care Centers (FQHC) in Southeast Michigan and 28 in-depth interviews with staff at two FQHC's and a non-profit agency serving immigrants. Findings suggest that immigrants face heightened anxiety and adverse mental health outcomes because of unique minority identity-related stressors created by a growing anti-immigrant social environment. Chronic stress experienced stems from restrictive immigration policies, anti-immigrant rhetoric in the media and by political leaders, fear of deportation, discriminatory events, concealment, and internalized anti-immigrant sentiment. Though identity can be an important effect modifier in the stress process, social isolation in the immigrant community has heightened the impact of stress and impeded coping strategies. These stressors have resulted in distrust in community resources, uncertainty about future health benefits, delayed medical care, and adverse mental health outcomes. Findings provide a framework for understanding the unique stressors experienced by immigrants and strategies for interventions by social service agencies.

A scoping review on the role of masculine norms in men's engagement in the HIV care continuum in sub-Saharan Africa.

Men living with HIV/AIDS in sub-Saharan Africa are less likely than women to be engaged at each stage of the HIV care continuum. We conducted a scoping review in May of 2016 to identify how masculine norms influence men's HIV care engagement in sub-Saharan Africa. Our review yielded a total of 17 qualitative studies from 8 countries. Six major themes emerged that demonstrated how norms of masculinity create both barriers and facilitators to care engagement. Barriers included the exacerbating effects of masculinity on HIV stigma, the notion that HIV threatened men's physical strength, ability to provide, self-reliance, and risk behavior, and the belief that clinics are spaces for women. However, some men transformed their masculine identity and were motivated to engage in care if they recognized that antiretroviral therapy could restore their masculinity by rebuilding their strength. These findings demonstrate masculinity plays an important role in men's decision to pursue and remain in HIV care across sub-Saharan Africa. We discuss implications for tailoring HIV messaging and counseling to better engage men and an agenda for future research in this area.

Correlates of HIV-infection among men who have sex with men: results from a community-based, cross-sectional study in Tianjin, China.

China has 747,000 confirmed HIV/AIDS cases and sexual transmission between men who have sex with men (MSM) is the most prevalent mode of transmission. Our study aims to (a) examine HIV prevalence and behavioral risk factors for HIV infection among 1900 MSM recruited from a community-based organization in Tianjin, China, and (b) describe HIV treatment outcomes for those diagnosed with HIV. We used multivariable logistic regression to identify which socio-demographics and behaviors were associated with HIV infection. The overall HIV prevalence was 3.95%. Key behavioral risk factors included: receptive sex role, older age at first sex with man, condomless anal sex, and having used 2+ drugs. Of those living with HIV, 83% were successfully enrolled in antiretroviral therapy and those enrolled were all virally suppressed after one year. These findings highlight key behavioral risk factors for HIV infection in Tianjin, China and can inform interventions to preventing further HIV transmission.

A qualitative study on the impact of the 2016 US election on the health of immigrant families in Southeast Michigan.

BACKGROUND: Given the anti-immigrant rhetoric and policy proposals by President Donald Trump during the 2016 presidential campaign and afterwards, his election to president in November 2016 and subsequent policy changes has affected immigrant families. In this study, we aim to better understand how post-election policy change may have impacted the health and well-being, including health and social service utilization, of Latino immigrants in Southeastern Michigan. METHODS: We conducted 28 in-depth interviews with frontline staff at two Federally Qualified Health Centers and a non-profit agency. These staff had intimate knowledge of and insights into the lived experiences of the mixed-status immigrant families they serve. The interviews were audio recorded, transcribed, and analyzed thematically. RESULTS: Our findings show three major themes: (1) An increased and pervasive fear of deportation and family separation among mixed-status immigrant clients, (2) The fear of deportation and family separation has resulted in fractures in community cohesion, and (3) Fear of deportation and family separation has had an impact on the healthcare utilization and health-related behaviors of mixed-status families. Staff members report that these three factors have had an impact on physical and mental health of these immigrant clients. CONCLUSIONS: These results add to previous literature on the effect of immigration policies on the health and provide key insights for interventions to improve the health of immigrants within this socio-political environment.

A sustainable business model for comprehensive medication management in a patient-centered medical home.

OBJECTIVES: To develop a sustainable business model for pharmacist-provided comprehensive medication management services in a patient-centered medical home. Secondarily, to evaluate the impact that the pharmacist had on clinical (glycosylated hemoglobin [A1C], low-density lipoprotein [LDL], and blood pressure) and economic (physician productivity and cost avoidance) outcomes. PRACTICE DESCRIPTION: This pilot project took place at the Palmetto Primary Care Physicians Trident office in North Charleston, South Carolina, from October 2013 to September 2014. At the time, the practice employed 5 physicians and 2 nurse practitioners and served more than 20,000 patients. PRACTICE INNOVATION: The pharmacist targeted patients with diabetes, lipid disorders, hypertension, congestive heart failure, obesity, polypharmacy, and treatment regimen nonadherence for his comprehensive medication management services. The pharmacist was available for immediate consultation or referrals by appointment 5 days per week. Services provided by the pharmacist were billed as medication therapy management or "incident to" physician evaluation and management services codes. EVALUATION: Number of patients seen per day, revenue collected from services rendered by the pharmacist, physician productivity and payment, cost avoidance, and health quality metrics (A1C, LDL, and blood pressure) were measured to determine the financial sustainability and clinical impact of the project. RESULTS AND IMPLICATIONS: The pharmacist was able to see an average of 11 patients per day, which was 72% of his capacity. The practice collected about $7400 per month for services rendered by the pharmacist. The average daily payment for services rendered by the physicians in the practice increased by 20.6%. More than 70% of uncontrolled patients had an improvement in clinical outcomes, such as A1C, LDL, and blood pressure. CONCLUSION: This project demonstrates the sustainable business model for embedding a pharmacist into a patient-centered medical home.

Competition and humiliation: how masculine norms shape men's sexual and violent behaviors.

We use data collected from in-depth interviews with men (n=30) in the Dominican Republic to explore how men's concern about being perceived as masculine influences their interactions with their social networks and how those interactions drive men's sexual behaviors and use of violence. Men's sexual and violent behaviors were shaped by the need to compete with other men for social status. This sense of competition also generated fear of humiliation for failing to provide for their families, satisfy sexual partners, or being openly disrespected. In an effort to avoid humiliation within a specific social group, men adapted their behaviors to emphasize their masculinity. Additionally, men who were humiliated recouped their masculinity by perpetrating physical or emotional violence or finding new sexual partners. These findings emphasize the need for understanding these social dynamics to better understand men's violent and sexual behaviors.

What Role Do Masculine Norms Play in Men's HIV Testing in Sub-Saharan Africa?: A Scoping Review.

Men living with HIV/AIDS in sub-Saharan Africa are less likely to test for HIV than women. We conducted a scoping review in May of 2016 to identify how masculine norms influence men's HIV testing in sub-Saharan Africa. Our review yielded a total of 13 qualitative studies from 8 countries. Masculine norms create both barriers and facilitators to HIV testing. Barriers included emotional inexpression, gendered communication, social pressures to be strong and self-reliant, and the fear that an HIV positive result would threaten traditional social roles (i.e., husband, father, provider, worker) and reduce sexual success with women. Facilitators included perceptions that HIV testing could restore masculinity through regained physical strength and the ability to re-assume the provider role after accessing treatment. Across sub-Saharan Africa, masculinity appears to play an important role in men's decision to test for HIV and further research and interventions are needed to address this link.
