Association between mental and physical health with poly-substance use among adults in 33 U.S. states

Abstract Leveraging national data from 33 states in the U.S. for adults 18 and over (N = 347,060), from the 2020-2022 Behavioral Risk Factor Surveillance System (BRFSS), we investigated the association between current self-reported physical and mental health outcomes and substance use, focusing on alcohol, nicotine, cannabis, and all combinations of poly-substance use. Specifically, we conducted multiple weighted linear regression analyses using self-reported outcomes for poor mental and physical health in the last 30 days to examine seven mutually exclusive combinations: alcohol (A) only, nicotine (N) only, cannabis (C) only, A+N, A+C, N+C, and A+N+C. We adjusted for race, sex, age group, education level, and marital status in our analyses. For poor mental health, mean number of days ranged from 3.49 (SD = 7.07) for A-only to 10.39 (SD = 11.54) for N+C and for poor physical health, means ranged from 2.38 (SD = 6.24) to 7.17 (10.61) for N+C. All adjusted β coefficients were significant for poor mental health days, notably with the three highest being 4.36 (95%CI: 3.72-5.00) for C-only, 5.68 (95%CI: 5.06-6.30) for N+C, and 5.27 (95%CI: 4.76-5.79) for A+N+C. For poor physical health, all adjusted β coefficients were significant except for A+N, with the two highest being 2.88 (95%CI: 2.31-3.45) for C-only, 3.16 (95%CI: 2.62-3.69) for N+C, and 1.83 (95%CI: 1.54-2.11) for N-only. Recent poly-substance use containing nicotine and cannabis was both associated with 5+ days of poorer mental health and 3+ days of poorer physical health. Overall, our findings hold implications for informing future policy discourse, shaping public health campaigns, and designing educational initiatives aimed at the link between mental health and substance use. Understanding the dynamics of poly-substance use involving the three most commonly utilized substances globally among adults is critical for crafting targeted interventions. Key messages • Recent poly-substance use (alcohol, nicotine, and cannabis) is related to poorer mental and physical health in the past 30-days. • Recent nicotine and cannabis co-use is associated with 5+ days of self-reported poorer mental health and 3+ days of physical health.

Experiences and Comfort of Young Cancer Patients Discussing Cannabis with Their Providers: Insights from a Survey at an NCI-Designated Cancer Center.

Cannabis use among cancer patients for managing treatment-related symptoms is increasing, yet little is known about patterns in patient-provider communication. This study examines demographic differences in cannabis use communication at a National Cancer Institute-designated cancer center. The analysis included cancer patients aged ≥ 18years who self-reported current cannabis use (past 30days) and had visited Sylvester Comprehensive Cancer Center within the past 5years (N = 226). Data were collected via an anonymous electronic survey on REDCap. Responses on patients' disclosure of cannabis use to cancer doctor/care team and their comfort in discussing cannabis were analyzed. Chi-squared/Fisher's exact tests and t-tests were applied. Logistic regression estimated the associations between age and stage of cancer treatment with patients' comfort in discussing cannabis use with cancer doctor (oncologist). The sample was 51.8% male and 39.4% Hispanic (mean age, 45.9years (SD = 15.1)); 41.1% were aged 20-39years, 43.8% were undergoing treatment, and 35.4% were in follow-up/had finished treatment. Over half (50.4%) did not disclose cannabis use to their cancer doctor/care team. Non-disclosers were more often younger (20-39years) than disclosers (52.6% vs. 29.5%, p < 0.01). Most patients (72.5%) felt comfortable discussing cannabis use with their oncologist; however, younger patients (20-39years) were more often uncomfortable (40.8%). Logistic regression showed newly diagnosed patients had lower odds (aOR, 0.41; 95% CI, 0.12-0.98) of comfort discussing cannabis compared to those in follow-up/finished treatment. Younger patients (20-39years) also had lower odds (aOR, 0.11; 95% CI, 0.03-0.40) of feeling comfortable discussing cannabis compared to older patients (≥ 60years). Age and treatment stage significantly impact the cannabis use disclosure and comfort in discussing it with cancer doctor/care team. These findings underscore the importance of considering age-related factors and treatment status when addressing cannabis use discussions within oncology setting.

Prevalence of Blunt and Hemp Wrap Use Among Young Adults in the United States, 2022

Introduction Blunt and hemp wraps, as a means of consuming cannabis, have emerged into the retail space where the prevalence has been increasing since 2017. There is limited epidemiological research on the prevalence of use of these products across the U.S. particularly among young adults who are at greater risk of tobacco and cannabis use. Methods This study draws from a U.S. national representative sample of young adults (n = 1178) captured in May 2022. Respondents participated in an online survey about their use of blunt and hemp wraps. Multinomial regression was used to examine differences in sociodemographic characteristics (gender, race/ethnicity, sexual orientation, educational attainment, and region) in relation to use of each wrap type. Results One quarter (22.7%) of young adults reported ever having used a blunt wrap, 3.2% in the past 30-days. One in seven (14.3%) had ever used a hemp wrap, 2.3% in the past 30-days. Non-Hispanic Black young adults were 1.55 and 2.91 times as likely to have ever used blunt or hemp wraps, respectively, compared to non-Hispanic Whites. Similarly, participants who identified as gay or lesbian or bisexual similarly had greater odds of having ever used blunt or hemp wraps. Hispanic young adults were 2.49 times as likely to have used hempwraps compared to non-Hispanic Whites. Conclusion Blunt and hemp wrap use is prevalent among young adults, particularly among minoritized populations. Continued research and surveillance of use of these products is needed to fully evaluate the impact their use may have on the broader population.

Highly active antiretroviral therapy adherence among HIV-POSITIVE women in Southern Ethiopia.

Adherence to Highly Active Antiretroviral Therapy (HAART) medication is the major predictor of HIV/AIDS treatment success. Poor adherence to HAART creates the risk of transmitting HIV, deteriorating health conditions, treatment failure, increased occurrences of drug-resistant HIV, morbidity and mortality. The objective of the study was to explore and describe factors influencing HAART adherence among HIV-positive women in Southern Ethiopia. A hospital-based descriptive cross-sectional survey was used among 220 randomly selected respondents. Data was collected with a structured interview guide after each respondent had given consent to take part in the study. The collected data was entered into and analyzed by using the Statistical Package for Social Sciences (SPSS) software program version 27. The level of self-reported adherence (measured by dose) to HAART in the past 30days was found to be 82.7%. In multivariate analysis, the divorced/separated HIV-positive women had poor adherence to their HAART medication as compared to those who were married [AOR: 2.94, 95% CI: (1.02-8.44)]. Respondents who used reminders in their medication were 75% less likely to be poorly adherent to their HAART medication than those who did not use reminders [AOR: 0.25, 95% CI: (0.06-0.97)]. Those who self-reported depression, perceived stigma, and low perceived susceptibility had poor adherence to their HAART than those who did not report depression, perceived stigma, and low perceived susceptibility [AOR:2.34, 95% CI: (1.01-5.42)], [AOR:2.37, 95% CI: (1.06-5.34)], and [AOR: 4.1, 95% CI: (1.53-11.1)] respectively. HIV-positive women who self-reported low perceived severity were poorly adherent to HAART than those who self-reported high perceived severity [AOR: 2.92, 95% CI: (1.14-7.47)]. Factors including being divorced/separated, not using reminders, depression, perceived stigma, perceived susceptibility, and perceived severity negatively impact HIV-positive women's adherence to HAART.

Association between body mass index and physical activity among prostate cancer survivors.

We assessed the associations between (1) body mass index (BMI) and participating in any physical activities (PAs) in past 30days and (2) cancer and behavioral-related variables and participating in any PAs in past 30days among prostate cancer (PCa) survivors. We conducted a cross-sectional analysis of data from the 2018-2022 Behavioral Risk Factor Surveillance System. Multivariable weighted logistic regression was used to examine the associations. Of the 4944 PCa respondents, 22.9% were classified as obese class I and 10.6% as obese class II or III. Obese class I and obese class II or III respondents were significantly less likely to participate in any PAs in past 30days (odds ratio (OR) = 0.48; 95% confidence interval (CI): 0.28-0.84 and OR = 0.37; 95% CI: 0.20-0.67, respectively). Men who received a summary of their cancer treatment were significantly more likely to participate in any PAs in past 30days (OR = 1.53; 95% CI: 1.03-2.28). Men who received instructions from a doctor for routine check-ups after completing treatment for cancer were not significantly more likely to participate in any PAs in past 30days (OR = 1.36; 95% CI: 0.87-2.12). Current smokers were less likely to participate in any PAs in past 30 days (OR = 0.50; 95% CI: 0.26-0.96). Obese men and current smokers were less likely to participate in any PAs in past 30days. Men who received a summary of their cancer treatment were more likely to participate in any PAs in past 30days. Health care providers should talk to their patients about the benefits of participating in PA and refer PCa patients to available exercise programs. PA was lowest among obese class II or III PCa survivors. These men could benefit from a coordinated multidisciplinary health care team effort to improve PCa prognosis and QoL.

Perceptions of Harm and Addictiveness for Nicotine Products, THC e-Cigarettes, and e-Cigarettes with Other Ingredients Among Adolescents, Young Adults, and Adults

Background Perceptions of health harms and addictiveness related to nicotine products, THC e-cigarettes, and e-cigarettes with other ingredients are an important predictor of use. This study examined differences in perceived harm and addiction across such products among adolescents, young adults, and adults. Methods We conducted a cross-sectional survey (N = 6,131, ages 13–40 years old) in which participants reported perceived harm and addictiveness for 11 products (cigarettes, disposable nicotine e-cigarettes, pod-based nicotine e-cigarettes, other nicotine e-cigarettes, THC e-cigarettes, e-cigarettes with other ingredients, nicotine pouches, nicotine lozenges, nicotine gums, nicotine tablets, nicotine toothpicks). We applied adjusted regression models and conducted pairwise comparisons between age groups (13–17, 18–20, 21–25, and 26–40) and product use status (never, ever, and past-30-day use), adjusting for gender, race/ethnicity, sexual orientation, and financial comfort. Results Overall, participants in younger age groups perceived products to be more harmful and addictive than those in older age groups, with the exception of e-cigarettes with other ingredients. For all products, participants who never used perceived each product to be more harmful than those who ever used. For all products, participants who used the products in the past 30-days had lower perceived harm and addictiveness compared to never and ever use. Certain sociodemographic groups, such as people who identify as LGBTQ+, Non-Hispanic Black, or Hispanic, had lower perceived harm and addictiveness for most products. Discussion Efforts should be made to educate all age groups and minoritized groups on harms and addictiveness of all nicotine products, THC e-cigarettes, and e-cigarettes with other ingredients.

Higher prevalence of polysubstance use among older lesbian, and gay US adults

IntroductionPolysubstance use (i.e., the use of more than one substance) is a major public health concern in the US that disproportionately hinders those from marginalized groups by sexual identity and age. Little research has examined this concern among lesbian, gay, and bisexual (LGB) older adults, and no study has measured past-30 day polysubstance use prevalence among these groups. The objective was to examine polysubstance use among older LGB adults compared to their heterosexual same-age peers and younger LGB counterparts. MethodsWe used the National Survey of Drug Use and Health 2021 and 2022 datasets with an analytic sample of 86,254 participants. Past-30 day polysubstance use prevalence was survey-weighted and adjusted by sociodemographic factors. We constructed Weighted multinomial models to compare polysubstance use between older LGB adults (65+ years old) with their same-age heterosexual and younger LGB counterparts. ResultsOlder Gay/Lesbian adults had a significantly higher polysubstance use prevalence than their heterosexual counterparts (OR = 27.94; p <0.001) while heterosexual participants showed a decline in polysubstance use with age (OR = 0.27; p < 0.001). Polysubstance use among gay/lesbian (OR = 0.67; p = 0.491) and bisexual (OR = 1.04; p = 0.969) older adults did not significantly differ from their younger counterparts. ConclusionsPolysubstance use is a public health concern for older gay/lesbian adults. Interventions are needed to address polysubstance use for older LGB adults, including early detection of polysubstance use and prevention strategies that are age and LGB inclusive.

A Qualitative Analysis of Shared Values and Motivation for Change Expressed by Sexual Minority Men in Relationships: Use of the Personal Values Card Sort Activity During Motivational Interviewing Sessions Addressing Drug Use and Sexual Health.

The development of tailored interventions that address drug use and sexual risk taking among sexual minority men (SMM) in relationships has garnered increasing interest over the past 20years. Motivational interviewing (MI) has demonstrated promise in both individual and couples-based applications. The Personal Values Card Sort activity is commonly employed in these interventions; however, relatively little is known about the content of client responses evoked by this intervention task. This study examined how SMM in relationships characterize their values; how their relationship partners influence value attainment; and how they situated drug use and sexual risk taking in the context of their values and primary relationships. A qualitative analysis of intervention transcripts from sessions with 47 SMM aged 18 to 34 was conducted. All respondents were HIV negative and indicated recent (past 30days) drug use and sexual risk behavior. Participants' high priority values reflected a focus on clarifying personal identity and interpersonal relationships. Values manifested as realized, aspirational, or transformed. Participants described their partners as supporting goal attainment and as a companion with whom they cope with goal-related stressors. Consistent with interdependence theory, participants' responses indicated consideration of their partner and relationship when these aligned with and supported goal-attainment. Conversely, when partners were described as a barrier to realizing their values, participants characterized their relationship as being of lower quality. Implications of this content for the activation of motivation for health behavior are discussed with specific emphasis on applications with SMM in relationships.

Clinical and genomic diversity of Treponema pallidum subspecies pallidum to inform vaccine research: an international, molecular epidemiology study

The increase in syphilis rates worldwide necessitates development of a vaccine with global efficacy. Weaimed to explore Treponema pallidum subspecies pallidum (TPA) molecular epidemiology essential for vaccine research by analysing clinical data and specimens from early syphilis patients using whole-genome sequencing (WGS) and publicly available WGS data. In this multicentre, cross-sectional, molecular epidemiology study, we enrolled patients with primary, secondary, or early latent syphilis from clinics in China, Colombia, Malawi, and the USA between Nov 28, 2019, and May 27, 2022. Participants aged 18years or older with laboratory confirmation of syphilis by direct detection methods or serological testing, or both, were included. Patients were excluded from enrolment if they were unwilling or unable to give informed consent, did not understand the study purpose or nature of their participation, or received antibiotics active against syphilis in the past 30days. TPA detection and WGS were conducted on lesion swabs, skin biopsies, skin scrapings, whole blood, or rabbit-passaged isolates. We compared our WGS data to publicly available genomes and analysed TPA populations to identify mutations associated with lineage and geography. We screened 2802patients and enrolled 233participants, of whom 77 (33%) had primary syphilis, 154 (66%) had secondary syphilis, and two (1%) had early latent syphilis. The median age of participants was 28years (IQR22-35); 154 (66%) participants were cisgender men, 77 (33%) were cisgender women, and two (1%) were transgender women. Of the cisgender men, 66 (43%) identified as gay, bisexual, or other sexuality. Among all participants, 56(24%) had HIV co-infection. WGS data from 113participants showed a predominance of SS14-lineage strains with geographical clustering. Phylogenomic analyses confirmed that Nichols-lineage strains were more genetically diverse than SS14-lineage strains and clustered into more distinct subclades. Differences in single nucleotide variants (SNVs) were evident by TPA lineage and geography. Mapping of highly differentiated SNVs to three-dimensional protein models showed population-specific substitutions, some in outer membrane proteins (OMPs) of interest. Our study substantiates the global diversity of TPA strains. Additional analyses to explore TPA OMP variability within strains is vital for vaccine development and understanding syphilis pathogenesis on a population level.

Views and experiences of involuntary civil commitment of people who use drugs in Massachusetts (Section 35)

BackgroundInvoluntary civil commitment (ICC) is a court-mandated process to place people who use drugs (PWUD) into substance use treatment. Research on ICC effectiveness is mixed, but suggests that coercive drug treatment like ICC is harmful and can produce a number of adverse outcomes. We qualitatively examined the experiences and outcomes of ICC among PWUD in Massachusetts. MethodsData for this analysis were collected between 2017 and 2023 as part of a mixed-methods study of Massachusetts residents who disclosed illicit drug use in the past 30-days. We examined the transcripts of 42 participants who completed in-depth interviews and self-reported ICC. Transcripts were coded and thematically analysed using inductive and deductive approaches to understand the diversity of ICC experiences. ResultsParticipants were predominantly male (57 %), white (71 %), age 31–40 (50 %), and stably housed (67 %). All participants experienced ICC at least once; half reported multiple ICCs. Participants highlighted perceptions of ICC for substance use treatment in Massachusetts. Themes surrounding ICC experience included: positive and negative treatment experience’s, strategies for evading ICC, disrupting access to medications for opioid use disorder (MOUD), and contributing to continued substance use and risk following release. ConclusionsPWUD experience farther-reaching health and social consequences beyond the immediate outcomes of an ICC. Findings suggest opportunities to amend ICC to facilitate more positive outcomes and experiences, such as providing sufficient access to MOUD and de-criminalizing the ICC processes. Policymakers, public health, and criminal justice professionals should consider possible unintended consequences of ICC on PWUD.

Estimating the causal effect of filter ventilation levels in cigarettes on past 30-day smoking.

Cigarettes with higher levels of filter ventilation are misperceived as less harmful and may be more appealing to consumers. Setting limits on filter ventilation has been considered as a policy, but a better understanding of any potential unintended consequences is needed. Filter ventilation (0.2-61.1%) measured for 114 subbrands was merged with Wave 1 (2012-2013) of the Population Assessment of Tobacco Use and Health (PATH) data, restricted to adults 25+ years of age who smoked daily, and examined by quartiles. Inverse probability of exposure weights were used to estimate the causal effect of filter ventilation on past-30 day smoking at subsequent waves while accounting for potential confounders including demographics, menthol, heaviness of smoking and past quit attempts. Compared to those in the 1st (lowest) quartile of filter ventilation, those in the 2nd, 3rd and 4th quartiles had 1.02 (95% confidence interval: 0.57, 1.82), 0.86 (0.42, 1.73) and 1.52 (0.90, 2.56) times the odds of no past 30-day smoking at Wave 2 (approximately 1 year later, p=0.163), and 1.28 (0.80, 2.07), 1.11 (0.67, 1.83) and 1.65 (1.01, 1.24) times the odds of no past 30-day smoking at Wave 4 (3 years later, p = 0.238). This observational study found no strong evidence of a causal effect of filter ventilation on past 30-day smoking at approximately 1 and 3 years follow-up. However, our effect size estimates were not precise and thus an increase in the ability to quit smoking due to higher filter ventilation levels cannot be ruled out. Setting a maximum limit on filter ventilation (FV) in cigarettes could address the misperception that highly ventilated cigarettes are less harmful and the link between FV and lung adenocarcinoma. It is important to understand whether such a policy would have unintended consequences on longer-term smoking behavior. We found no strong evidence that FV affects past 30-day smoking 1-3 years later, but could not rule out the possibility that higher FV increases cessation rates. If future studies confirm these epidemiologic findings, this could mean that setting a limit on FV would not lead to reductions in the ability to quit smoking.

The gut-immune-liver axis in patients with alcohol use disorder and clinically low serum zinc levels.

Alcohol use disorder (AUD) with chronic and heavy alcohol consumption causes alcohol-associated liver disease (ALD). Early-stage ALD exhibits dyshomeostasis of zinc. We investigated the role of zinc deficiency in gut-barrier dysfunction, proinflammatory response, hepatocyte injury, and death, as well as potential sex differences in AUD patients. Thirty-nine male and female AUD patients were grouped by normal [≥71 μg/dL (Group 1, number (n) = 26)] and low [<71 μg/dL (Group 2, n = 13)] serum zinc levels. Demographics, alcohol intake markers [Lifetime Drinking History (LTDH), heavy drinking days in the past 90-days (HDD90), total drinks in the past 90-days (TD90), number of drinking days in the past 90-days (NDD90), average drinks per day in the past 90 days (AvgDPD90)] were collected. Blood samples were tested for complete blood count (CBC), comprehensive metabolic panel (CMP), coagulation markers, gut-barrier dysfunction markers, cytokines, and hepatocyte death markers. Group 2 females exhibited lower LTDH than Group 2 males (p = 0.028), but higher recent drinking. Aspartate transaminase: alanine transaminase (AST:ALT) ratio was higher (p = 0.049) in Group 2 males compared to Group 1 males. Overall, Group 2 showed threefold higher interleukin 8 (IL-8) levels than Group 1 (p = 0.92); these were sevenfold higher in Group 2 females than Group 1 females. Group 2 females also had higher K18M65, but lower K18M30 than Group 1 females. Necrotic type of cell death (K18M65) was well-described only in Group 2 by the arrangement of lipopolysaccharide (LPS), soluble cluster of differentiation 14 (sCD14), and tumor necrosis factor alpha (TNF-α) (R2 = 0.633, p = 0.037). Our findings demonstrated the role of the gut-immune-liver axis in describing hepatocyte injury and death in zinc-deficient AUD patients. These patients represented an arrangement of gut-barrier dysfunction and an exacerbated immune response. Shift in the cell-death mechanism from apoptosis in zinc-replete females to necrosis in zinc-deficient females suggests a subclinical to clinical transition of ALD associated with zinc status.

Extensive social media use and frequency of current e-cigarette use among US youth

IntroductionBoth electronic cigarette (e-cigarette) and social media use among youth are public health concerns. While the health impacts of extensive social media use and frequent use of e-cigarettes have been discussed independently in the literature, little is known about the relationship between the two. This study aims to examine the potential association between extensive social media use and the frequency of current, e-cigarette use among United States (US) youth. MethodsData from the 2022 National Youth Tobacco Survey (NYTS) were analyzed. The sample included 23,655 middle and high school students aged 9–18 years. Frequency of current e-cigarette use was categorized based on past-30 day use (i.e., never/former, 1–9 days, 10–29 days, or 30 days). Social media use was dichotomized into less than 4 hours daily and 4+ hours daily (i.e., extensive use). Multivariable multinomial logistic regression estimated the relationship between social media use and e-cigarette use frequency. ResultsOver one-third (35.8 %) of youth used social media extensively and 8.6 % reported current use of e-cigarettes. Extensive social media use was associated with daily e-cigarette use (OR: 1.94, 95 % CI: 1.48–2.56) but not with other use categories. Older age, female sex, lower grades, current other tobacco use, and family tobacco use were also associated with daily e-cigarette use. ConclusionsExtensive social media use is associated with daily e-cigarette use among US youth. Public health interventions should consider the influence of social media on tobacco use behaviors and tailor prevention strategies to address this potential modifiable risk factor.

Youth use of electronic nicotine delivery systems (ENDS) in the Population Assessment of Tobacco and Health (PATH) Wave 6: Impact of survey mode

BackgroundThe Population Assessment of Tobacco and Health (PATH) provides annual prevalence data on youth use of electronic nicotine delivery systems (ENDS). However, trends may be complicated by COVID-related changes in survey mode (self-completed vs. telephone interview) across 2019–2021. MethodsTrends in past 30-day (P30D) ENDS use over PATH waves 5 (2019; 100 % self-completed), 5.5 (2020; 100 % telephone interview), and 6 (2021; 33.5 % self-completed, 66.5 % telephone interview) were examined among continuing youth, overall and within survey mode. Further analyses examined the nature of these changes by examining 1) potential response biases in social contexts of nicotine use, and 2) sources of ENDS over time. ResultsTelephone interviewees were less likely to report ENDS use (4.6 % vs. 8.6 % for self-completers), and more likely to report social disapproval of nicotine use, suggesting a reporting bias in telephone interviews. Survey-mode-naïve analyses suggested a large decline in P30D ENDS use prevalence between 2019–20 (10.2–4.6 %) followed by an apparent uptick in 2021 (5.9 %); however, comparing like-to-like survey modes showed a more modest decline (10.2 % in 2019; 8.6 % in 2021; self-completed) with no change between 2020 and 2021 (4.6 % in both; telephone interviews). Analyses suggested that the mode effects were partly, but not wholly, related to social desirability effects. DiscussionChanges in PATH survey mode introduced artifacts into ENDS use prevalence, possibly due in part to social desirability bias suppressing reporting in telephone interviews, rather than a true uptick. It is essential to account for survey mode in PATH surveys.

Triple network resting-state functional connectivity patterns of alcohol heavy drinking.

Previous neuroimaging research in alcohol use disorder (AUD) has found altered functional connectivity in the brain's salience, default mode, and central executive (CEN) networks (i.e. the triple network model), though their specific associations with AUD severity and heavy drinking remains unclear. This study utilized resting-state fMRI to examine functional connectivity in these networks and measures of alcohol misuse. Seventy-six adult heavy drinkers completed a 7-min resting-state functional MRI scan during visual fixation. Linear regression models tested if connectivity in the three target networks was associated with past 12-month AUD symptoms and number of heavy drinking days in the past 30days. Exploratory analyses examined correlations between connectivity clusters and impulsivity and psychopathology measures. Functional connectivity within the CEN network (right and left lateral prefrontal cortex [LPFC] seeds co-activating with 13 and 15 clusters, respectively) was significantly associated with AUD symptoms (right LPFC: β = .337, p-FDR = .016; left LPFC: β = .291, p-FDR = .028) but not heavy drinking (p-FDR > .749). Post-hoc tests revealed six clusters co-activating with the CEN network were associated with AUD symptoms-right middle frontal gyrus, right inferior parietal gyrus, left middle temporal gyrus, and left and right cerebellum. Neither the default mode nor the salience network was significantly associated with alcohol variables. Connectivity in the left LPFC was correlated with monetary delay discounting (r =.25, p = .03). These findings support previous associations between connectivity within the CEN network and AUD severity, providing additional specificity to the relevance of the triple network model to AUD.

Use of cigarettes and e-cigarettes, impulsivity and anxiety: Influences on suicidal ideation among youth and young adults in Texas.

Cigarette use and smoking intensity increase risk of suicidal ideation. Less is known about e-cigarette use. Here we examine direct influences of cigarette versus e-cigarette use on suicidal ideation among 16-to-23-year-olds in Texas. Since 2019 the Texas Adolescent Tobacco and Marketing Surveillance study collected data on suicidal ideation every six months covering the previous two-weeks. Youths answering that they had "thoughts that you would be better off dead, or of hurting yourself" on more than two of 14 days were categorized as having suicidal ideation. Generalized linear mixed-effects logistic regressions examined the influence of ever and past 30-day (P30D) use of cigarettes, e-cigarettes, impulsivity and anxiety on suicidal ideation, controlling for gender, race/ethnicity, SES, and grade in school. Interactions between ever and P30D use of both products and a) impulsivity and b) gender were examined. Of the 2,329 participants, 29.1% reported ever and 6.5% reported P30D cigarette use, 48.2% reported ever and 11.6% reported P30D e-cigarette use, and 18.5% reported suicidal ideation. Ever cigarette use among females (aOR=1.83; 95% CI: 1.36-2.46), P30D e-cigarette use (aOR=1.30; 95% CI: 1.00-1.68), and P30D cigarette use (aOR=1.47; 95% CI: 1.06-2.05) were independently associated with higher risk for suicidal ideation, after adjusting for covariates. Impulsivity and anxiety directly increased risk for suicidal ideation regardless of product type used. Hispanic youth had higher risk of suicidal ideation than white youth, while higher levels of SES were protective. Cigarette/e-cigarette use, as well as impulsivity and anxiety, directly increase the risk of suicidal ideation. Clinicians should ask young adults with a history of tobacco use, anxiety or impulsive behavior, about suicidal ideationNicotine prevention and cessation programs might be more effective if they simultaneously target substance use and mental healthCulturally appropriate support is needed for ethnic and racial minority youth and young adults in school, college and at workWhen evaluating and understanding risk, the role of multiple social identities (such as minority status, gender, and SES) is important.

Bloodstream infections due to multi-drug resistant bacteria in the emergency department: prevalence, risk factors and outcomes-a retrospective observational study.

Multidrug-resistant organisms (MDROs) are prevalent in patients admitted to the Emergency Department (ED) and increase the risk of inappropriate empirical antibiotic therapy. Risk stratification for MDRO infection is essential to early identify patients requiring empirical broad-spectrum antibiotic therapy, but it remains challenging for emergency physicians. This study aimed to evaluate prevalence, risk factors, and outcomes of patients admitted to the ED with a bloodstream infection (BSI) caused by MDROs. A retrospective observational study enrolling all consecutive adult patients admitted with a BSI to the ED of Niguarda Hospital, Italy, from January 2019 to December 2021 was performed. 757 patients were enrolled, 14.1% with septic shock. 156 (20%) patients had a BSI caused by MDRO: extended-spectrum beta-lactamase (ESBL) producing Enterobacterales were the most prevalent followed by methicillin-resistant Staphylococcus aureus (MRSA). Risk factors for BSI due to MDRO and specifically for ESBL were chronic renal failure (OR 2.2; 95%CI 1.4-3.6), nursing home residency (OR 4.4; 95%CI 1.9-10.2) and antibiotic therapy in the last 90-days (OR 2.6; 95%CI 1.7-4), whereas for MRSA were dialysis (OR 12.3; 95%CI 1.8-83), antibiotic therapy and/or hospital admission in the past 90-days (OR 3.6; 95%CI 1.2-10.6) and ureteral stent or nephrostomy (OR 7.8; 95%CI 1.5-40.9). Patients with BSI due to MDRO had a higher rate of inappropriate empirical antibiotic therapy (50%) and longer length of stay, but no higher in-hospital mortality. Among patients admitted to the ED with a BSI, MDROs are frequent and often associated with inappropriate empirical antibiotic therapy. Specific updated risk factors for MDRO may help clinicians to better identify patients requiring a broader antibiotic therapy in the ED, while awaiting microbiological results.

Changes in alcohol consumption during the COVID-19 among first-year university students in Spain, considering the risk of problematic use – UniHcos project

The aim of this study was to evaluate the possible impact of the COVID-19 pandemic on prevalence rates and self-reported changes in patterns of alcohol use among first-year university students in Spain, considering the risk of problematic alcohol use. A serial cross-sectional study based on the uniHcos project was carried out. Data from 10 518 first-year university students (73.3% female, mean age 19 (SD = 1.6)) collected between 2012 and 2022 were analysed. The evolution of the pooled prevalence rates during the time series was analysed and the risk of problematic alcohol consumption was assessed using the AUDIT. Also, self-reported changes in alcohol use patterns during the pandemic were assessed. According to the results, during the COVID-19 pandemic, the prevalence of alcohol use in the past 30-days was reduced (76.3% in 2019 vs. 63.7% in COVID-19) increasing again in the New Normal period. Thus, a similar pattern in the practice of binge drinking was observed. Regarding the AUDIT score, 21.7% (95%CI 20.9, 22.6) of the students had harmful alcohol consumption, with a higher proportion among males. In the multivariable logistic models, a higher AUDIT score was significantly associated (p-value < 0.001) with being male and living with roommates. According to self-reported changes in consumption patterns during the COVID-19 pandemic, a higher proportion of participants with harmful use reported an increase in alcohol consumption compared to those at low-risk (43% vs 19%). Finally, despite the overall reduction in drinking prevalence during COVID-19, changes were not equal for all students and depended on their previous level of problematic drinking, highlighting that this should be considered in the development of strategies against alcohol use in this population.

Minority stressors and tobacco use among a US sample of sexual and gender minority young adults

IntroductionYoung adults who are sexual and gender minorities (SGM) are at the highest risk for tobacco initiation in young adulthood. Minority stress theory suggests that sexual orientation and gender identity (SOGI)-based discrimination may contribute to nicotine and tobacco use disparities. Our study aimed to quantify the association between SOGI-based distal minority stressors and current tobacco use among SGM young adults living in the United States (US). MethodsEligible participants—including young adults (aged 18–35 years old), who identified as SGM, and were currently residing in the US (N=1116) —were recruited via Prolific into an online survey. We applied stepwise binary regressions with backward selection to model the association between average past 30-day distal minority stress and current tobacco use (i.e., combustible cigarettes or e-cigarettes), controlling for perceived stress and sociodemographic covariates. We also tested interactions between minority stress and SGM status. Exploratory analyses assessed associations between minority stress and current tobacco use among YA, stratified by SGM subgroup. ResultsA 1-unit increase in experiencing minority stress in the past 30-days was associated with 1.02 greater odds of current tobacco use among SGM young adults. No difference between SGM subgroups in this association was found. Examining stratified SGM subgroups, a 1-unit increase in minority stress was associated with 1.11 greater odds of current tobacco among transgender adults only. ConclusionDistal minority stress is differentially associated with current tobacco use for transgender young adults, which suggests that tobacco prevention and cessation interventions may need tailoring for subgroups. ImplicationsThis study details the influence of minority stress on current tobacco use among sexual and gender minority (SGM) young adults. Findings underscore the need for targeted and tailored approaches to tobacco control, wherein SGM young adults most at-risk are engaged in cessation interventions that address minority stress as a contributing factor to tobacco use and which support their resilience. To promote health equity, tobacco control must address the contexts that engender minority stress. Assessment of policy impacts on SGM tobacco use and the effectiveness of interventions disseminated within SGM-supportive and discriminatory policy environments are important next steps.

The impact of intimate partner violence on PrEP adherence among U.S. Cisgender women at risk for HIV

BackgroundCisgender women account for 1 in 5 new HIV infections in the United States, yet remain under-engaged in HIV prevention. Women experiencing violence face risk for HIV due to biological and behavioral mechanisms, and barriers to prevention, such as challenges to Pre-Exposure Prophylaxis for HIV Prevention (PrEP) adherence. In this analysis, we aim to characterize intimate partner violence (IPV) among cisgender heterosexual women enrolled in a PrEP demonstration project and assess the associations with PrEP adherence.MethodsAdherence Enhancement Guided by Individualized Texting and Drug Levels (AEGiS) was a 48-week single-arm open-label study of PrEP adherence in HIV-negative cisgender women in Southern California (N = 130) offered daily tenofovir disoproxil fumarate/emtricitabine (TDF/FTC). From 6/2016 to 10/2018, women completed a survey reporting HIV risk behavior and experiences of any IPV (past 90-days) and IPV sub-types (past-year, lifetime) and biological testing for HIV/STIs at baseline, and concentrations of tenofovir-diphosphate (TFV-DP) in dried blood spots at weeks 4, 12, 24, 36, and 48. Outcomes were TFV-DP concentrations consistent with ≥ 4 or ≥ 6 doses/week at one or multiple visits. Multivariable logistic regression models were conducted to examine associations.ResultsPast-90-day IPV was reported by 34.4% of participants, and past-year and lifetime subtypes reported by 11.5-41.5%, and 21.5-52.3%, respectively. Women who engaged in sex work and Black women were significantly more likely to report IPV than others. Lifetime physical IPV was negatively associated with adherence at ≥ 4 doses/week at ≥ 3 of 5 visits, while other relationships with any IPV and IPV sub-types were variable.ConclusionIPV is an indication for PrEP and important indicator of HIV risk; our findings suggest that physical IPV may also negatively impact long-term PrEP adherence.Clinical Trials RegistrationNCT02584140 (ClinicalTrials.gov), registered 15/10/2015.
