Exploring patterns in mental health treatment and interests of single adults in the United States: a secondary data analysis.

Objective: The objective of this study is to examine mental health treatment utilization and interest among the large and growing demographic of single adults in the United States, who face unique societal stressors and pressures that may contribute to their heightened need for mental healthcare. Method: We analyzed data from 3,453 single adults, focusing on those with possible mental health treatment needs by excluding those with positive self-assessments. We assessed prevalence and sociodemographic correlates of mental health treatment, including psychotherapy and psychiatric medication use, and interest in attending psychotherapy among participants who had never attended. Results: 26% were in mental health treatment; 17% were attending psychotherapy, 16% were taking psychiatric medications, and 7% were doing both. Further, 64% had never attended psychotherapy, of which 35% expressed interest in future attendance. There were differences in current psychotherapy attendance and psychiatric medication use by gender and sexual orientation, with women and gay/lesbian individuals more likely to engage in both forms of mental health treatment. Additionally, interest in future psychotherapy among those who had never attended varied significantly by age, gender, and race. Younger individuals, women, and Black/African-American participants showed higher likelihoods of interest in psychotherapy. Conclusion: Our research highlights a critical gap in mental health treatment utilization among single adults who may be experiencing a need for those services. Despite a seemingly higher likelihood of engagement in mental health treatment compared to the general population, only a minority of single adults in our sample were utilizing mental health treatment. This underutilization and the observed demographic disparities in mental health treatment underscore the need for targeted outreach, personalized treatment plans, enhanced provider training, and policy advocacy to ensure equitable access to mental healthcare for single adults across sociodemographic backgrounds.

Personal identification using frontal sinus coding methods: The effect of mixed image modality comparisons.

Several code-based methods have been created for comparing the frontal sinus in skeletal identification scenarios. However, little is known regarding matched-pair accuracy rates of these methods or how varying image modalities may affect these rates. The goals of this study were to validate the exclusion rates and to establish matched-pair accuracy rates of two well-cited coding methods, Cameriere et al. [23] and Tatlisumak et al. [24]. Additionally, individual variables were assessed for consistency in scoring between image modalities. Using a sample of U.S. African American, Native American, and European American females and males (n = 225), we examined individual variable scoring and string codes between two different image modalities (radiographs and CT-based 3D models). Arcades showed poor scoring consistency between modalities (p < 0.001). Although exclusion rates were similar to those reported in the original studies (93%-96%), matched-pair accuracy rates were low (13%-18%). None of the demographics (collection, sex, age, ancestry, and orientation) had an effect on the odds of a match. Interobserver and intraobserver analyses showed moderate to near-perfect agreement for all variables except supraorbital cells, which had minimal to no agreement. Currently, we do not recommend the application of these frontal sinus coding methods independent of other supporting identification methods given low variable consistency and accuracy rates. Visual identification should still be used to include or exclude an identification when using the frontal sinus.

The Human Interference Scoring System (HISS): A New Tool for Quantifying Food Quality Based on Its Level of Processing.

The Human Interference Scoring System (HISS) is a novel food-based diet-quality-classification system based on the existing NOVA method. HISS involves food and fluid allocation into categories from digital imagery based on food processing levels, followed by meal plan analysis using food-servings quantification. The primary purpose of this work was to evaluate the reliability of HISS. Trained nutrition professionals analyzed digital photographs from five hypothetical 24 h food recalls and categorized foods into one of four HISS categories. A secondary purpose was to assess the nutrient composition of the food recalls and other selected foods from the HISS categories. Participants effectively categorized foods into HISS categories, with only minor discrepancies noted. High inter-rater reliability was observed in the outer HISS categories: unprocessed and ultra-processed foods. Ultra-processed items consistently displayed elevated energy, carbohydrates, and sugar compared to unprocessed foods, while unprocessed foods exhibited notably higher dietary fiber. This study introduces the HISS as a potentially useful tool for quantifying a food-quality-based system using digital-photography-based assessments. Its high inter-rater reliability and ability to capture relationships between food processing levels and nutrient composition make it a promising method for assessing dietary habits and food quality.

Exploring the Orgasm Gap Across Racial/Ethnic Groups: A Descriptive Analysis.

Orgasm gaps between heterosexual men and women, and for women across sexual orientations, are well-established in research. However, no large-scale assessments of orgasm frequency by race/ethnicity exist. Here, we analyzed 10 years of cross-sectional Singles in America survey data between 2011 and 2021 to investigate the orgasm gap at the intersection of gender and racial/ethnic identity (i.e. White, Black, Hispanic/Latino, and Asian) for heterosexual participants (N = 27,347). White and Hispanic/Latino men reported greater orgasm frequency than Black and Asian men. Hispanic/Latino women reported the greatest orgasm frequency, and Asian women reported the lowest, with White and Black women's frequencies in between. The orgasm gap between men and women was largest for White (d = 0.89) and Asian (d = 0.86) groups, although Asian participants reported a lower orgasm frequency than White participants overall. The orgasm gap was smaller for Hispanic/Latino participants (d = 0.66), because Hispanic/Latino women reported a greater orgasm frequency than other racial/ethnic groups of women. The orgasm gap was smaller for Black participants (d = 0.61), because Black men reported a lower orgasm frequency than some other racial/ethnic groups of men. This descriptive study serves as an important starting point for future research on orgasm experiences across racial/ethnic groups.

Women Who Experience More Affectionate Touch Report Better Body Satisfaction and Relationship Outcomes.

Affectionate touch (e.g. hugging, handholding) is an essential component of many intimate relationships and is a primary contributor to overall relationship satisfaction as well as sexual satisfaction. Affectionate touch is understood to be a form of non-verbal communication in which the giver is expressing positive feelings toward the receiver. Here, we propose that affectionate touch also positively impacts receivers' body satisfaction, because affectionate touch is a positive message communicated toward the receiver's body. In a cross-sectional sample of romantically partnered women (N = 1,156), we assessed the association between affectionate touch frequency and body satisfaction. We also investigated whether affectionate touch is associated with relationship/sexual satisfaction in part because touch helps to improve women's evaluations of their own bodies. Our results showed that body satisfaction was a significant, partial mediator and a valid path through which affectionate touch shapes relationship quality. Receiving affectionate touch could bolster relationship satisfaction and self-perceptions among women. Given the prevalence of body dissatisfaction amongst women, these results suggest that the underexplored associations between affectionate touch and body satisfaction may have significant impacts on a wide array of future empirical and applied research trajectories.

User Perception of Smart Home Surveillance Among Adults Aged 50 Years and Older: Scoping Review.

BACKGROUND: Smart home technology (SHT) can be useful for aging in place or health-related purposes. However, surveillance studies have highlighted ethical issues with SHTs, including user privacy, security, and autonomy. OBJECTIVE: As digital technology is most often designed for younger adults, this review summarizes perceptions of SHTs among users aged 50 years and older to explore their understanding of privacy, the purpose of data collection, risks and benefits, and safety. METHODS: Through an integrative review, we explored community-dwelling adults' (aged 50 years and older) perceptions of SHTs based on research questions under 4 nonmutually exclusive themes: privacy, the purpose of data collection, risk and benefits, and safety. We searched 1860 titles and abstracts from Ovid MEDLINE, Ovid Embase, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials, Scopus, Web of Science Core Collection, and IEEE Xplore or IET Electronic Library, resulting in 15 included studies. RESULTS: The 15 studies explored user perception of smart speakers, motion sensors, or home monitoring systems. A total of 13 (87%) studies discussed user privacy concerns regarding data collection and access. A total of 4 (27%) studies explored user knowledge of data collection purposes, 7 (47%) studies featured risk-related concerns such as data breaches and third-party misuse alongside benefits such as convenience, and 9 (60%) studies reported user enthusiasm about the potential for home safety. CONCLUSIONS: Due to the growing size of aging populations and advances in technological capabilities, regulators and designers should focus on user concerns by supporting higher levels of agency regarding data collection, use, and disclosure and by bolstering organizational accountability. This way, relevant privacy regulation and SHT design can better support user safety while diminishing potential risks to privacy, security, autonomy, or discriminatory outcomes.

Exploring the usability and feasibility of a mobile music listening application for people living in the community with post-stroke aphasia.

PURPOSE: Language and communication disorders can inhibit participation in activities that have potential therapeutic benefits for recovery. This exploratory research examined the usability and feasibility of a purpose-built music listening mobile application for people living in the community with post-stroke aphasia, and examined relationships between useability and participant age, aphasia severity and time post-stroke. METHODS: Nineteen participants with chronic aphasia tested the application for two weeks. Prior to use, music preferences, technology use and confidence, self-efficacy and music engagement questionnaires were completed. System usability scale, music listening data and a satisfaction rating were completed following use. RESULTS: Overall, the application was perceived as being usable and feasible with a high system usability rating and moderate effectiveness, efficiency and satisfaction. The system usability scores were not associated with aphasia severity, age, years post-stroke, self-efficacy or music engagement. Technology confidence was positively associated with system usability. CONCLUSION: The music listening application is a feasible and usable option for listening to music in people with chronic post-stroke aphasia. This study provides a foundation for the rigorous examination of the usability of music listening technology for people with post-stroke aphasia and the potential investigation of use in acute care facilities and other clinical populations.IMPLICATIONS FOR REHABILITATIONMusic listening has potential therapeutic benefits for people with post-stroke aphasia.Applications for music listening require customisation to enable people with post-stroke aphasia opportunity to listen to their preferred music.Music listening applications that are perceived as usable and feasible by people with post-stroke aphasia may have potential application within rehabilitation and community settings.

Medical Mistrust and Healthcare Seeking Among Women of Color with Chronic Vulvovaginal Pain.

BACKGROUND: Chronic vulvovaginal pain (CVVP), an umbrella term encompassing several gynecological pain conditions (e.g., vulvodynia, vaginismus), has a prevalence rate of 7-8% in the USA and is characterized by considerable diagnostic delay in patient experience research. Furthermore, current research in this area focuses largely on the experiences of white women, while the experiences of women of color are underrepresented. METHOD: In the present cross-sectional study (N = 488), we surveyed women of color (i.e., Asian, Black, and/or Hispanic/Latinx women) with CVVP about their perceptions and experiences with medical mistrust, healthcare seeking, and healthcare avoidance. RESULTS: Using the suspicion subscale of the Group-Based Medical Mistrust Scale, we found significant racial and ethnic differences in medical suspicion scores, with non-Black Hispanic/Latinx women reporting the highest suspicion scores and non-Hispanic/Latinx Black women reporting the lowest scores. Racial differences disappeared, however, after examining medical mistrust and perceived discrimination as predictors for various healthcare outcomes related to the journey to diagnosis and healthcare avoidance behaviors. We found that while suspicion was a reliable predictor of increased diagnostic delay and healthcare avoidance in many contexts, the results for perceived discrimination were more varied, suggesting considerable nuance in the relationship between medical mistrust, perceived discrimination, and healthcare seeking outcomes. CONCLUSION: These findings point to shared experiences of medical mistrust via suspicion that broadly characterize women of color's experiences in seeking CVVP-related care-future research is needed to examine nuances within racial and ethnic groups regarding their healthcare seeking experiences in the CVVP context.

An innovative passive sampling approach for the detection of cyanobacterial gene targets in freshwater sources.

Cyanotoxins pose significant human health risks, but traditional monitoring approaches can be expensive, time consuming, and require analytical equipment or expertise that may not be readily available. Quantitative polymerase chain reaction (qPCR) is becoming an increasingly common monitoring strategy as detection of the genes responsible for cyanotoxin synthesis can be used as an early warning signal. Here we tested passive sampling of cyanobacterial DNA as an alternative to grab sampling in a freshwater drinking supply lake with a known history of microcystin-LR. DNA extracted from grab and passive samples was analyzed via a multiplex qPCR assay that included gene targets for four common cyanotoxins. Passive samples captured similar trends in total cyanobacteria and the mcyE/ndaF gene responsible for microcystin production when compared to traditional grab samples. Passive samples also detected genes associated with the production of cylindrospermopsin and saxitoxin that were not detected in grab samples. This sampling approach proved a viable alternative to grab sampling when used as an early warning monitoring tool. In addition to the logistical benefits of passive sampling, the detection of gene targets not detected by grab samples indicates that passive sampling may allow for a more complete profile of potential cyanotoxin risk.

Vision in the Vertical Axis: How Important Are Visual Cues in Foraging and Navigation?

In both terrestrial and aquatic environments, a large number of animal behaviors rely on visual cues, with vision acting as the dominant sense for many fish. However, many other streams of information are available, and multiple cues may be incorporated simultaneously. Being free from the constraints of many of their terrestrial counterparts, fish have an expanded range of possible movements typified by a volume rather than an area. Cues such as hydrostatic pressure, which relates to navigation in a vertical plane, may provide more salient and reliable information to fish as they are not affected by poor light conditions or turbidity. Here, we tested banded tetra fish (Astyanax fasciatus) in a simple foraging task in order to determine whether visual cues would be prioritized over other salient information, most notably hydrostatic pressure gradients. We found that in both vertical and horizontal arrays there was no evidence for fish favoring one set of cues over the other, with subjects making choices at random once cues were placed into conflict. Visual cues remained as important in the vertical axis as they were in the horizontal axis.

American Singles' Attitudes Toward Future Romantic/Sexual Partners' COVID-19 Vaccination Status: Evidence for both Vigilance and Indifference in a National Sample.

Around 142 million American adults are currently single; at least half of these singles want to pursue a romantic partner. Romantic dating can involve exposure to numerous people. Thus, dating can significantly impact pathogen exposure risk. In a demographically-representative cross-sectional survey conducted in 2021 (N = 5,000), we examined U.S. American singles' COVID-19 vaccination status, assessed their preferences around a potential partner's COVID-19 vaccination status, and identified demographic subgroups of singles particularly opposed to or indifferent to a partner being vaccinated against COVID-19. Our results showed 65% of participants were fully vaccinated, 10% were partially vaccinated, and 26% were unvaccinated against COVID-19. With regards to partner preferences, half wanted a vaccinated partner; 18.9% wanted a vaccinated partner but would make exceptions; 6.1% wanted an unvaccinated partner; and 25% reported that they did not care about their dating partner's vaccination status. Partner preferences were largely aligned with participants' own vaccination status, such that vaccinated participants preferred vaccinated partners. However, those preferring unvaccinated partners-or those willing to make exceptions for a partner-were most likely to identify as men, younger in age, a political affiliation outside of the two-party political system, a gender or sexual minority, or as a racial minority (i.e., Black/African-American or South Asian). Additionally, participants who were employed (vs. unemployed) were more likely to make exceptions for or prefer an unvaccinated partner. These results suggest that singles prefer homophily in COVID-19 vaccine status, and that minoritized subgroups of singles are more likely to maintain a social network including unvaccinated close others.

Transfusion of ABO-group identical red blood cells following uncrossmatched transfusion does not lead to higher mortality in civilian trauma patients.

BACKGROUND: Questions persist about the safety of switching non-group O recipients of group O uncrossmatched red blood cells (RBC) or low titer group O whole blood (LTOWB) to ABO-identical RBCs during their resuscitation. METHODS: The database of an earlier nine-center study of transfusing incompatible plasma to trauma patients was reanalyzed. The patients were divided into three groups based on 24-h RBC transfusion: (1) group O patients who received group O RBC/LTOWB units (control group, n = 1203), (2) non-group O recipients who received only group O units (n = 646), (3) non-group O recipients who received at least one unit of group O and non-group O units (n = 562). Fixed marginal effect of receipt of non-O RBC units on 6- and 24-h and 30-day mortality was calculated. RESULTS: The non-O patients who received only group O RBCs received fewer RBC/LTOWB units and had slightly but significantly lower injury severity score compared to control group; non-group O patients who received both group O and non-O units received significantly more RBC/LTOWB units and had a slightly but significantly higher injury severity score compared to control group. In the multivariate analysis, the non-O patients who received only group O RBCs had significantly higher mortality at 6-h compared to the controls; the non-group O recipients of O and non-O RBCs did not demonstrate higher mortality. At 24-h and 30-days, there were no differences in survival between the groups. CONCLUSION: Providing non-group O RBCs to non-group O trauma patients who also received group O RBC units is not associated with higher mortality.

The Influence of Health Care Provider-Initiated HIV Screening on the Rate of HIV Testing among Black and Latinx People in the Midwest.

HIV continues to impact people of color disproportionately. In 2015, Black Americans accounted for 42% of those living with HIV, and Latinx individuals accounted for 30% of new diagnoses. Using a sample of 364 people of color, demographic data, HIV testing history, and interactions with health care providers were collected. Over half of the participants (59.3%) had never been offered an HIV test, and only 19% reported a provider had offered an HIV test once, followed by 14% who have had a provider offer an HIV test more than once. Participants who were offered an HIV test once were 13.23 times more likely to report a history of HIV screening, and those offered an HIV test more than once were 18.02 times more likely to report a history of HIV testing. Participants who reported feeling a "little" judged were 6.85 times less likely to report being screened for HIV.

Early postoperative complications following tracheotomy: Does suturing technique influence outcomes?

Introduction: Tracheotomy is one of the most commonly performed procedure by otolaryngologists, but no consensus exists on the effect of suturing techniques on postoperative complications. Stay sutures and Bjork flaps are utilized frequently for securing the tracheal incision to the neck skin in order to create a tract for recannulation. Methods: Retrospective cohort study of tracheotomies performed by Otolaryngology-Head and Neck Surgery providers (May 2014 to August 2020) was conducted to determine the effect of suturing technique on postoperative complications and patient outcomes. Patient demographics, medical comorbidities, indication for tracheostomy, and postoperative complications were analyzed with a statistical alpha set of .05. Results: Out of 1395 total tracheostomies performed at our institution during the study period, 518 met inclusion criteria for this study. Three hundred and seventeen tracheostomies were secured by utilizing a Bjork flap, while 201 were secured with up and down stay sutures. Neither technique was noted to be more commonly associated with tracheal bleeding, infection, mucus plugging, pneumothorax, or false passage of the tracheostomy tube. One mortality was noted following decannulation during the study period. Conclusion: Though various techniques exist; adverse outcomes are not associated with the manner in which a new tracheostomy stoma is secured. Medical comorbidities and the indications for tracheostomy likely play a more significant role in postoperative outcomes and complications. Level of evidence: Level 3.

COVID-19: Reducing the risk via diet and lifestyle.

This review shows that relatively simple changes to diet and lifestyle can significantly, and rapidly, reduce the risks associated with coronavirus disease 2019 (COVID-19) in terms of infection risk, severity of disease, and even disease-related mortality. A wide range of interventions including regular exercise, adequate sleep, plant-based diets, maintenance of healthy weight, dietary supplementation, and time in nature have each been shown to have beneficial effects for supporting more positive health outcomes with COVID-19, in addition to promoting better overall health. This paper brings together literature from these areas and presents the argument that non-pharmaceutical approaches should not be overlooked in our response to COVID-19. It is noted that, in several cases, interventions discussed result in risk reductions equivalent to, or even greater than, those associated with currently available vaccines. Where the balance of evidence suggests benefits, and the risk is minimal to none, it is suggested that communicating the power of individual actions to the public becomes morally imperative. Further, many lives could be saved, and many harms from the vaccine mandates avoided, if we were willing to embrace this lifestyle-centred approach in our efforts to deal with COVID-19.

PrEP Prescription Among MSM U.S. Military Service Members: Race and Sexual Identification Matter.

An estimated 20.9% of U.S. service members report a high risk of HIV infection; however, only 2,000 service members had accessed HIV pre-exposure prophylaxis (PrEP) as of 2017. This study used a cross-sectional design to explore PrEP prescription predictors among service members who identify as a man who have sex with other men (MSM) (n = 354). Logistic regression was performed to assess the influence of four predictor variables: partner HIV status, race/ethnicity, primary partner gender, and sexual orientation on the odds participants' report being prescribed PrEP. A majority identified as gay (n = 246, 69.5%) and 23.4% (n = 83) identified as bisexual. Bisexual participants were 2.1 times (p = <.04) less likely to be prescribed PrEP. Accordingly, those who identify their primary sex partner as female were 5.1 times less likely to be prescribed PrEP (p < .001). MSM service members who had a partner disclose their HIV-positive status were 4.1 times more likely to have been prescribed PrEP (p = .013). Finally, participants who identify as Black were 3 times more likely (p = .001), and Latinx MSM were 3.6 times more likely (p = .003) to have been prescribed PrEP.

Technical Modifications for the Application of the Total Difference Method for Frontal Sinus Comparison.

Despite being used in personal identification since the 1920s, frontal sinus-based methods are rarely validated. This study is a validation test of the Total Difference Method (TDM). The posterior-anterior radiographs of 10 adults were assessed by two observers using three modes: the Freehand Mode largely followed the original protocols; the Overlay Mode utilized a tracing overlay; and the Semi-Auto Mode used the overlay and macro, walking the user through multiple steps. The modes were evaluated for the time taken to complete each image and the accuracy and repeatability of the line lengths, midline assessment, and angle placement. The repeated measures analysis of variance results for the intra-observer error revealed differences in bias in the angle placement and line length mean error between the rounds and modes. The differences between the rounds were approximately consistent for each mode, suggesting observer error. Significant differences in the inaccuracy of the angle placement and the line lengths between observers by mode were evident; in post hoc testing, the Freehand Mode and Overlay Mode had the greatest error in both variables (p.adj < 0.0001). The Semi-Auto Mode retained no significant error for angle inaccuracy and had the fewest errors for line length inaccuracy (p.adj < 0.01). When using the Semi-Auto Mode, the time was 46.1% faster than that of the Freehand Mode and 34% faster than that of the Overlay Mode (F2,18 = 52.71, p < 0.0001); time slightly improved with method familiarity. The results suggest that the technique required for the TDM can reliably be repeated, and the semi-automated macro improves accuracy and efficiency, but only after the users are familiar with the method and macro procedures. All resources needed to repeat this study are freely available on GitHub.

Can we call Anne Lister a lesbian?

The introductions of scholarly works on queer desire between eighteenth- and nineteenth-century British women typically pose some version of the question "do they count as lesbians?" Historians and literary critics have responded with a variety of answers; while some embrace the term "lesbian" despite the anachronism, others hesitate, using words like "Sapphic" or longer phrases like "women who loved women" to characterize the object of study. Indeed, in the absence of a noun or a recognized social role for women who loved other women before the twentieth century, the ways such women conceptualized themselves necessarily diverge from modern lesbian identity. But although the hesitation to use modern terminology makes sense in the case of many women, I argue in this paper that Anne Lister (1791-1840) is an exception. From her own descriptions in her extensive diaries, it is clear that Lister's thoughts, feelings, and actions are largely consistent with modern lesbian identity-particularly given that "modern lesbian identity" is not a monolith. I support this contention by examining evidence from the journals themselves as well as by considering recent arguments that focus on the fluidity and capaciousness of terminology itself. Finally, I suggest that applying the word "lesbian" to Lister is a strategic way to communicate the extent of her relationships with women to a public that still sometimes refuses to admit that such relationships existed in the past.

Identity and weight-related beliefs among Black, Black/White biracial, East Asian, Hispanic/Latino, Native American, South Asian, and White U.S. Americans.

In the current study we move away from bias-focused, White-centric research to examine relationships between gender, race/ethnicity, and weight-related attitudes, identity, and beliefs among Black, Black/White Biracial, East Asian, Hispanic/Latino, Native American, South Asian, and White U.S. Americans who self-identify as higher weight. The results showed that: (1) women identify as fat more than men do, (2) fat identity, operationalized as feelings of similarity to fat people (self-stereotyping) and importance of weight to one's sense of self (identity centrality) are relatively similar across races and ethnicities, and (3) fat identity and weight-related beliefs are related to positivity toward fat people across the racial/ethnic groups sampled in this study.

Pre- and Post-Redesign Usability Assessment of a Telemedicine Interface Based on Subjective Metrics.

Usability problems in the interaction between patients and telemedicine platforms has been recognized as a deterrent in the public's acceptance and use of this alternative healthcare delivery method. Therefore, evaluating the usability of telemedicine provider websites, with a focus on potential patients' first interaction with telemedicine, is a critical research inquiry. To this end, a novel survey was developed to conduct an unmoderated remote usability test (URUT) of the Teladoc website. Teladoc is one of the largest providers of Direct-to-Consumer (DTC) telemedicine. The Teladoc Website Usability Survey (TWUS) instrument collected both objective task completion success metrics and subjective user feedback. A codebook was developed to categorize design features and user interface aspects that affected usability. The TWUS and codebook demonstrated value in identifying usability problems with the Teladoc interface and can be applied in other telemedicine or Health Information Technology (HIT) usability studies. Identifying and addressing usability issues is an important approach to increase the widespread acceptance and adoption of these healthcare delivery technologies.
