Factors Associated with Erectile Dysfunction Among Older Gay Men.

Erectile dysfunction (ED) is a common issue that aging men encounter, but whether internalized gay ageism (i.e., the internalization of ageist messages within the context of aging as a gay man) is related to ED among older gay men is unknown. A cross-sectional web-based survey explored the relationship between internalized gay ageism, health-related and social factors, and ED among older gay men who resided in the Midwest United States (N = 181). Internalized gay ageism was not significantly associated with ED. However, hierarchical regression analysis found that age (ß = .224, t = 2.70, p = .008) and overall health (ß = -.247, t = -3.05, p = .003) were significantly associated with ED among older gay men, suggesting that older gay men share similar risk factors for ED as the general male population. Future research should continue to explore other factors that are unique to gay men that may be associated with ED.

Prevalence and Correlates of Food Insecurity Among Older Adults in the United States.

This study analyzed the 2021 National Health Interview Survey (NHIS) to assess food insecurity among adults aged 65 and older. Among 8,877 older adults, 4 percent (N=287) reported low or very low food security levels. Those who identified as Black or African American and Hispanic or Latino were more likely to experience food insecurity compared to White individuals. The study found that merely surpassing the poverty threshold might not be sufficient to protect against food insecurity. It also underscored socioemotional support's protective role in older adults' food security. Social workers must recognize various factors influencing food security among older adults.

Dementia literacy and worry among older Chinese Americans in Arizona: a comparison between 2013 and 2017.

OBJECTIVES: This study examined the change in dementia literacy and dementia worry over a 5-year span among older Chinese Americans living in Arizona. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENT: This study used survey data collected among a purposive sample of 703 community-dwelling Chinese Americans aged 55 years or older living in the metropolitan areas of Phoenix, Arizona, from 2013 to 2017. The average age of participants was 73.1 (SD = 8.7) and 64.2% were female. Dementia literacy was measured by dementia knowledge (knowledge about Alzheimer's disease and related dementia) and dementia beliefs (biased attitude toward dementia). Dementia worry was measured by assessing participants' fear toward and concerns of developing dementia. RESULTS: Regression analyses found dementia knowledge decreased (p < 0.05) and dementia beliefs remained unchanged (p > 0.05) from 2013 to 2017 among participants. Dementia worry only increased among those who lived alone. Significant correlates of dementia worry included low formal education level, depressive symptoms, and family conflict. CONCLUSIONS: Public health education targeting older Chinese Americans should aim to enhance dementia knowledge and to rectify their biased attitudes toward dementia. Psychosocial education or counseling should be available to older Chinese Americans who present dementia worry, particularly for those who live alone. More studies using diverse study designs, such as a longitudinal design, are needed to examine change in dementia literacy and worry among this population.

Worries, strategies, and confidence of older Chinese adults during the 2019 novel coronavirus outbreak.

OBJECTIVES: Since the novel coronavirus disease (COVID-19) outbreak started in late 2019, the older population has accounted for a large proportion of severe and fatal cases. This study investigated the mental state and attitudes of older Chinese adults during this epidemic. DESIGN: Cross-sectional online surveys on a convenience sample of China's general population at two different time points. Online surveys were disseminated through popular Chinese social media applications. Adults 18 or older living in China during the initial (N = 1148) and second stages (N = 470) were included in the survey. The Worries, Strategies, and Confidence Questionnaire was created to assess worries and awareness of the disease. RESULTS: Combined responses (N = 1618), 76.1% were female and about 7.0% were 60 years or above. In the first wave, older adults were found less likely to worry about being infected by COVID-19 (p < 0.05) and reported less attention paid to protective measures (p = 0.004) than young adults. However, as the disease evolved, older participants in the second wave were more worried than young adults (p = 0.027) and older adults in the first wave (p = 0.001). CONCLUSIONS: During the epidemic of COVID-19, watchfulness of the epidemic among older Chinese adults fluctuated over time. Initially, they were slow to respond proactively, but their worries gradually increased. Health care and social service professionals need to address the vulnerabilities of older adults to this public health crisis.

A Nickel(II)-Containing Vitamin†B12 Derivative with a Cofactor-F430-type π-System.

F430 is a unique enzymatic cofactor in the production and oxidation of methane by strictly anaerobic bacteria. The key enzyme methyl coenzyme M reductase (MCR) contains a hydroporphinoid nickel complex with a characteristic absorption maximum at around 430 nm in its active site. Herein, the three-step semisynthesis of a hybrid NiII -containing corrinoid that partly resembles F430 in its structural and spectroscopic features from vitamin B12 is presented. A key step of the route is the simultaneous demetalation and ring closure reaction of a 5,6-secocobalamin to metal-free 5,6-dihydroxy-5,6-dihydrohydrogenobalamin with cobaltocene and KCN under reductive conditions. Studies on the coordination chemistry of the novel compound support an earlier hypothesis why nature carefully selected a corphin over a corrin ligand in F430 for challenging nickel-catalyzed biochemical reactions.

Antivitamins for Medicinal Applications.

Antivitamins represent a broad class of compounds that counteract the essential effects of vitamins. The symptoms triggered by such antinutritional factors resemble those of vitamin deficiencies, but can be successfully reversed by treating patients with the intact vitamin. Despite being undesirable for healthy organisms, the toxicities of these compounds present considerable interest for biological and medicinal purposes. Indeed, antivitamins played fundamental roles in the development of pioneering antibiotic and antiproliferative drugs, such as prontosil and aminopterin. Their development and optimisation were made possible by the study, throughout the 20th century, of the vitamins' and antivitamins' functions in metabolic processes. However, even with this thorough knowledge, commercialised antivitamin-based drugs are still nowadays limited to antagonists of vitamins B9 and K. The antivitamin field thus still needs to be explored more intensely, in view of the outstanding therapeutic success exhibited by several antivitamin-based medicines. Here we summarise historical achievements and discuss critically recent developments, opportunities and potential limitations of the antivitamin approach, with a special focus on antivitamins K, B9 and B12 .

Social and Mental Health Factors Associated with Sexual Satisfaction Among Older Gay Men.

The internalization of ageist stereotypes or messages based on the framework of an aging gay man is known as internalized gay ageism. Internalized gay ageism may influence an older gay man's sexual satisfaction. The aim of this study was to examine the relationship between internalized gay ageism and sexual satisfaction and determine if body image was a potential mediator. A cross-sectional online survey collected data on sexual satisfaction and other variables related to sexual health and well-being among older gay men. Inclusion criteria included: aged 50 or older, identified as gay, identified as male, assigned male at birth, and resided in the Midwestern region of the United States. Descriptive, bivariate, and mediation analyses were conducted. A complete mediation effect was found between internalized gay ageism and sexual satisfaction when mediated by body image. Older gay men who were in open relationships were more sexually satisfied than single/widowed older gay men. Future research should continue to explore internalized gay ageism, relationship status, body image, and sexual satisfaction among older gay men.

Mental Health of Older Adults by Sexual Minority Status: Evidence From the 2021 National Health Interview Survey.

This study explored differences among older adults in mental health by sexual minority status. Data came from the 2021 U.S. National Health Interview Survey. The study sample included older adults (or those aged ≥50 years, N = 15,559), and of those, two percent (n = 380) self-identified as lesbian, gay, or bisexual (LGB). Older LGB adults had significantly higher odds of reporting a diagnosis of depression and anxiety and experiencing serious psychological distress than older non-LGB adults. Additionally, older LGB adults reported higher odds of experiencing depression and anxiety more frequently than older non-LGB adults. Significant covariates included age, sex, housing, food security, and social support. Increased risk for mental illness may be long-term consequences of stigma and discrimination that this population has experienced over the life course. The combination of structural interventions and affirming mental healthcare that recognizes the cumulative negative experience among older LGB adults is necessary to achieve mental health equity.

Prescription Pain Reliever Misuse Among Transgender and Gender Diverse Adults.

Purpose: Little is known about the prevalence and risks associated with transgender and gender diverse (TGD) persons' misuse of prescription pain relievers (PPRs). This study explores the relationship between PPR misuse and various sociodemographic identities and experiences of discrimination in health care among TGD adults. Methods: TGD participants (n=595) were recruited in 2018 to participate in a cross-sectional statewide trans health survey through convenience sampling. Chi-square tests of independence and logistic regressions were conducted to explore associations between sociodemographics and experiences of discrimination among persons who had ever misused PPRs, or who had misused PPRs in the past year. Results: Sociodemographics such as gender identity (odds ratio [OR]=0.44, p=0.01), race/ethnicity (OR=0.14, p<0.001), and sexual orientation influence TGD individuals likeliness of misusing PPRs (OR=0.40, p<0.001). Notably, those who were ever diagnosed with anxiety had a higher likeliness of having lifetime PPR misuse compared with those who were never diagnosed (OR=2.05, p=0.05), and those reporting past-year discrimination within the mental health care setting because of their gender identity were more than twice as likely to report past-year misuse than those who reported not experiencing it (OR=2.43, p=0.004). Conclusion: Certain subpopulations of TGD individuals may be at elevated risk of PPR misuse. It is imperative to acknowledge the impact of multimarginalized identities as well as differences across various identities and experiences within the TGD community while working to address non-PPR misuse.

Newly self-administered two-step tool for screening cognitive function in an ageing Chinese population: an exploratory cross-sectional study.

Background: Early screening of cognitive function is critical to dementia treatment and care. However, traditional tests require face-to-face administration and are often limited by implementation costs and biases. Aims: This study aimed to assess whether the Thoven Cognitive Self-Assessment (TCSA), a novel, innovative two-step touchscreen-based cognition assessment tool, could identify early cognitive impairment due to dementia in older adults. Methods: The TCSA was administered to 61 healthy controls (HCs), 46 participants with mild cognitive impairment (MCI) and 44 participants diagnosed with dementia recruited from Shanghai. Two outcome measures were generated from the TCSA test: the TCSAprimary task score and the TCSAsecondary task score. Results: The total average scores in the control group for the TCSAprimary task and TCSAsecondary task were significantly higher than those in the MCI and dementia groups (TCSAprimary task: HCs vs MCI group vs dementia group, 8.58±1.76 vs 5.40±2.67 vs 2.74±2.11, F=75.40, p<0.001; TCSAsecondary task: HCs vs MCI group vs dementia group, 23.02±3.31 vs 17.95±4.93 vs 11.93±5.50, F=76.46, p<0.001). Moreover, receiver operating characteristic analysis showed that a score below 7.5 for the TCSAprimary task and a score below 22.5 for the TCSAsecondary task were indicators of MCI. Conclusions: The TCSA appears to be efficacious for the detection of cognitive impairment in older adults. It demonstrates the potential for large-scale cognition screening in community service settings.

Gynecological Providers' Willingness to Prescribe Gender-Affirming Hormone Therapy for Transgender Patients.

Purpose: Transgender individuals face barriers to accessing gender-affirming hormone therapy, yet little is known about gynecological providers' willingness to provide such care. Methods: We surveyed gynecological providers in one healthcare system to determine their willingness to prescribe hormone therapy (HT) for transgender patients and factors associated with willingness to both initiate and refill HT. Results: Among respondents (N = 60), 60.3% and 27.6% were willing to refill and initiate HT for transgender patients, respectively. Willingness to refill HT was associated with having met a transgender person and lower transphobia. Unwillingness was associated with lack of transgender health training, lack of staff knowledge about transgender health, and unfamiliarity with transition guidelines. Willingness to initiate HT was associated with younger age and resident status. Unwillingness was associated with unfamiliarity with transition guidelines. Conclusion: While gynecological providers are qualified to prescribe HT for transgender patients, willingness to do so may be influenced by both personal and educational/training factors. Encouraging and training gynecological providers to provide gender-affirming HT will help to increase access for transgender individuals.

Dementia-friendly initiatives within the context of COVID-19 pandemic: Challenges and strategies perceived by service professional stakeholders from the USA and China.

PURPOSES: Dementia-friendly initiatives (DFI) are community-based movements aimed to address stigma, exclusion, and discrimination associated with dementia. This study examined the challenges faced and strategies used by DFI prior to and during the COVID-19 pandemic from the perspectives of stakeholders in the USA and China. METHODS: Qualitative interviews with 17 stakeholders involved in DFI from the United States and mainland China were conducted via the Zoom platform. Semi-structured interview questions focused on DFI challenges and strategies prior to and during the pandemic. Thematic analysis was used to analyze the data. RESULTS: Three major challenges prior to the COVID-19 pandemic included low participation of persons with dementia, difficulties in building community collaborations, and limited funding and resources needed to sustain DFI. During the COVID-19 pandemic, challenges included exacerbated difficulties of involving persons with dementia and reduced policy support for DFI. Strategies implemented prior to COVID-19 included partnerships with community organizations to outreach and engage persons with dementia, and coordination of resources and diversification of funding sources to sustain DFI. Strategies during the COVID-19 pandemic centered on the implementation of person-centered technology to support persons with dementia and family caregivers, and the development of new programs that integrated efforts to address the impact of COVID-19. IMPLICATIONS: DFI in the USA and mainland China shared similar challenges for DFI prior to and during COVID-19. During the COVID-19 pandemic, DFI in both countries showed resourcefulness through reliance on technology, community collaboration, and COVID-19-related resources to provide support and services. While it remains critical to advocate to the central government to fund DFI, DFI in both societies need to be open to other funding sources, hire persons with dementia as key staff members of DFI, and demonstrate its effectiveness through rigorous evaluation.

Suicide Attempts Among a Cohort of Transgender and Gender Diverse People.

INTRODUCTION: Transgender and gender diverse people often face discrimination and may experience disproportionate emotional distress that leads to suicide attempts. Therefore, it is essential to estimate the frequency and potential determinants of suicide attempts among transgender and gender diverse individuals. METHODS: Longitudinal data on 6,327 transgender and gender diverse individuals enrolled in 3 integrated healthcare systems were analyzed to assess suicide attempt rates. Incidence was compared between transmasculine and transfeminine people by age and race/ethnicity and according to mental health status at baseline. Cox proportional hazards models examined rates and predictors of suicide attempts during follow-up. Data were collected in 2016, and analyses were conducted in 2019. RESULTS: During follow-up, 4.8% of transmasculine and 3.0% of transfeminine patients had at least 1 suicide attempt. Suicide attempt rates were more than 7 times higher among patients aged <18 years than among those aged >45 years, more than 3 times higher among patients with previous history of suicide ideation or suicide attempts than among those with no such history, and 2-5 times higher among those with 1-2 mental health diagnoses and more than 2 mental health diagnoses at baseline than among those with none. CONCLUSIONS: Among transgender and gender diverse individuals, younger people, people with previous suicidal ideation or attempts, and people with multiple mental health diagnoses are at a higher risk for suicide attempts. Future research should examine the impact of gender-affirming healthcare use on the risk of suicide attempts and identify targets for suicide prevention interventions among transgender and gender diverse people in clinical settings.

Gynecologic Health Care Providers' Willingness to Provide Routine Care and Papanicolaou Tests for Transmasculine Individuals.

Background: Transmasculine individuals who have a cervix may be at risk of cervical cancer, but they face a number of barriers to accessing care, including difficulty finding knowledgable and culturally sensitive providers who are willing to care for transgender patients. We examined gynecologic health care providers' willingness to provide routine care and Papanicolaou tests (Pap tests) to transmasculine individuals, including the role of personal, clinical, and professional factors. Materials and Methods: We surveyed attending physicians, advanced practitioners, and residents in the Women's Health department of a large, integrated Midwest health system (n = 60, 74.1% response rate). Results: A majority of participants were female (68.3%) and white (73.3%). Most had met a transgender person before (79.7%), and 40.7% had cared for a transgender patient in the past 5 years. Most reported willingness to provide routine care (74.6%) and Pap tests (85.0%) to transmasculine people. Bivariate analysis suggests that having met a transgender person (p = 0.028), higher empathy scores (p = 0.015), political views (p = 0.0130), and lower transphobia (p = 0.012) were associated with willingness to provide routine care to transmasculine individuals. Lower transphobia (p = 0.034) and political views (p < 0.001) were also associated with willingness to provide Pap tests to transmasculine people. Conclusions: Providers' willingness was not associated with barriers related to training or knowledge-only with personal biases and experiences. Transgender-inclusive health care training that addresses personal attitudes should be a routine part of training for all health professionals.

Modified biovectors for the tuneable activation of anti-platelet carbon monoxide release.

This communication describes the anti-platelet effects of a new class of cis-rhenium(ii)-dicarbonyl-vitamin B12 complexes (B12-ReCORMs) with tuneable CO releasing properties.

Inorganic Cyanide as Protecting Group in the Stereospecific Reconstitution of Vitamin B12 from an Artificial Green Secocorrinoid.

The synthesis of vitamin B12 in four steps from an artificial green secocorrinoid is presented. The stereospecific reconstitution of the B-ring of the cobalamin involves a quantitative and rapid ligand-centered radical ring closure reaction leading first to a new B12 derivative with antivitamin activity that is subsequently converted to the natural product. Chemoselectivity in the one-electron reduction of the macrocycle was achieved by introducing inorganic cyanide as an axially coordinating protecting group of the otherwise reduction-sensitive CoIII-ion. The integrity of structure and function of the reconstituted natural product was unequivocally proven by single crystal structural analysis and a microbiological assay using Lactobacillus leichmannii.

Influence of ligation method on friction resistance of lingual brackets with different second-order angulations: an in vitro study.

OBJECTIVE: To evaluate stainless steel archwire static friction in active and passive self-ligating lingual and conventional brackets with second-order angulations. METHODS: Two conventional lingual brackets for canines (STb light/Ormco; PSWb/Tecnident), and two self-ligating brackets, one active (In-Ovation L/GAC) and the other passive (3D/ Forestadent), were evaluated. A stainless steel archwire was used at 0°, 3° and 5° angulations. Metal ligatures, conventional elastic ligatures, and low friction elastic ligatures were also tested. A universal testing machine applied friction between brackets and wires, simulating sliding mechanics, to produce 2-mm sliding at 3 mm/minute speed. RESULTS: Two-way analysis of variance demonstrated a significant effect of the interaction between brackets and angulations (p < 0.001). Tukey test indicated that the highest frictional resistance values were observed at 5° angulation for In-Ovation L, PSWb bracket with non conventional ligature, and STb bracket with metal ligature. As for 3D, PSWb with conventional or metal ligatures, and STb brackets with non conventional ligature, showed significantly lower static frictional resistance with 0° angulation. At 0° angulation, STb brackets with metal ties, In-Ovation L brackets and 3D brackets had the lowest frictional resistance. CONCLUSIONS: As the angulation increased from 0° to 3°, static friction resistance increased. When angulation increased from 3° to 5°, static friction resistance increased or remained the same. Self-ligating 3D and In-Ovation L brackets, as well as conventional STb brackets, seem to be the best option when sliding mechanics is used to perform lingual orthodontic treatment.

Synthesis of a B ring opened 7,8-seco-vitamin B12 derivative with Grob fragmentation.

A synthetic route toward B ring opened 7,8-seco-cyanocobalamins is described. Hydrolysis of a novel c-lactone vitamin B12 (B12) derivative generates a cobalamin (Cbl) with a ß-bromo alcoholate subunit that reacts in situ via Grob fragmentation to the secocorrin.
