Essential Fatty Acid Deficiency is Common after Total Pancreatectomy and Islet AutoTransplantation.

OBJECTIVES: Total pancreatectomy and islet autotransplantation (TPIAT) for pancreatitis may induce risk for essential fatty acid deficiency (EFAD) due to exocrine pancreatic insufficiency and intestinal alterations. The prevalence of EFAD post-TPIAT is currently unknown. METHODS: We abstracted essential fatty acid (EFA) profiles (n = 332 samples) for 197 TPIAT recipients (72% adult, 33% male). Statistical analyses determined the prevalence of, and associations with, EFAD post-operatively. EFAD was defined as a Triene-to-Tetraene ratio ≥ 0.05 if <18 years old, or ≥ 0.038 if ≥18 years old. RESULTS: Prevalence of EFAD was 33%, 49%, and 53.5% at 1, 2, and ≥ 3 years. At 1 year post-TPIAT, older age at transplant (p = 0.03), being an adult versus a child (p = 0.0024), and obstructive etiology (p = 0.0004) were significant predictors of EFAD. Only 6% of children had EFAD 1 year post-TPIAT vs. 46% of adults. ALA levels were lower with lower BMI at transplant (p = 0.011). EFAD was associated with the presence of other intestinal diseases (p < 0.0001). CONCLUSIONS: One-third of individuals had EFAD 1 year post-TPIAT, highlighting the need for systematic monitoring. Older age at transplant increased risk and adults were more affected than children. Other diagnoses affecting intestinal health may further increase risk for EFAD.

Can incorporating molecular testing improve the accuracy of newborn screening for congenital adrenal hyperplasia?

BACKGROUND: Single-tier newborn screening (NBS) for CAH using 17-hydroxyprogesterone (17OHP) measured by fluoroimmunoassay (FIA) in samples collected at 24-48 hours produces a high false-positive rate (FPR). 2nd tier steroid testing can reduce the FPR and has been widely implemented. We investigated the accuracy of an alternative multi-tier CAH NBS protocol that incorporates molecular testing of the CYP21A2 gene and reduces the 1st tier 17OHP cutoff to minimize missed cases. METHODS: Created a Minnesota-specific CYP21A2 pathogenic variants panel; develop a rapid, high-throughput multiplex, allele-specific-primer-extension assay; perform 1-year retrospective analysis of Minnesota NBS results comparing metrics between a conventional steroid-based two-tier protocol and a molecular-based multi-tier NBS protocol, applied post-hoc. RESULTS: CYP21A2 gene sequencing of 103 Minnesota families resulted in a Minnesota-specific panel of 21 pathogenic variants. Centers for Disease Control and Prevention (CDC) created a molecular assay with 100% accuracy and reproducibility. Two-tier steroid-based screening of 68,659 live births during 2015 resulted in 2 false negatives (FNs), 91 FPs, and 1 true positive (TP). A three-tier protocol with a lower 1st-tier steroid cutoff, 2nd-tier 21-variant CYP21A2 panel and 3rd-tier CYP21A2 sequencing would have resulted in 0 FNs, 52 FPs and 3 TPs. CONCLUSIONS: Incorporation of molecular testing could improve the accuracy of CAH NBS, although some distinct challenges of molecular testing may need to be considered before implementation by NBS programs.

Impact of Early-Life Adversity on Cannabis Use: Exploring the Mediating and Moderating Effects of Chronic Pain.

Background: Although research suggests that early-life adversity (ELA) and cannabis use are linked, researchers have not established factors that mediate or modify this relationship. Identifying such factors could help in developing targeted interventions. We explored chronic pain as a potential mediator or moderator of this relationship. Methods: Using an online study, we collected cross-sectional data about ELA, cannabis use, and chronic pain to test whether ELA (adverse childhood experiences total score) is associated with cannabis use, and to examine pain as a potential mediator or moderator. Cannabis use was examined two ways: times used per day, and categorized as non-, some, or regular use. Chronic pain was measured as present/absent and as the number of painful body locations (0-8). Analyses used linear and multinomial regression. Results: ELA, chronic pain, and cannabis use were common among respondents. ELA was strongly associated with both measures of cannabis use. The number of painful body locations modestly mediated the association of ELA with cannabis use, reducing the magnitude of regression coefficients by about 1/7. The number of painful body locations modified the association between ELA and cannabis use (p≤0.006), while chronic pain presence/absence (a less-informative measure) had only a nonsignificant modification effect (p≥0.10). When either ELA or pain was high, the other was not associated with cannabis use; when either ELA or pain was low, more painful locations or higher ELA (respectively) was associated with more intense cannabis use. Conclusion: These exploratory findings suggest the importance of ELA and chronic pain as factors contributing to cannabis use, and of accounting for these factors in developing treatment and prevention strategies addressing cannabis use.

Peri-Transplant Inflammation and Long-Term Diabetes Outcomes Were Not Impacted by Either Etanercept or Alpha-1-Antitrypsin Treatment in Islet Autotransplant Recipients.

The instant blood-mediated inflammatory response (IBMIR) causes islet loss and compromises diabetes outcomes after total pancreatectomy with islet autotransplant (TPIAT). We previously reported a possible benefit of etanercept in maintaining insulin secretion 3 months post-TPIAT. Here, we report 2-year diabetes outcomes and peri-operative inflammatory profiles from a randomized trial of etanercept and alpha-1 antitrypsin (A1AT) in TPIAT. We randomized 43 TPIAT recipients to A1AT (90 mg/kg IV x6 doses, n = 13), etanercept (50 mg then 25 mg SQ x 5 doses, n = 14), or standard care (n = 16). Inflammatory cytokines, serum A1AT and unmethylated insulin DNA were drawn multiple times in the perioperative period. Islet function was assessed 2 years after TPIAT with mixed meal tolerance test, intravenous glucose tolerance test and glucose-potentiated arginine induced insulin secretion. Cytokines, especially IL-6, IL-8, IL-10, and MCP-1, were elevated during and after TPIAT. However, only TNFα differed significantly between groups, with highest levels in the etanercept group (p = 0.027). A1AT increased after IAT in all groups (p < 0.001), suggesting endogenous upregulation. Unmethylated insulin DNA ratios (a marker of islet loss) and 2 years islet function testing were similar in the three groups. To conclude, we found no sustained benefit from administering etanercept or A1AT in the perioperative period.

The Impacts of Inclusionary State Immigrant Policies on Psychosocial Outcomes Among Latinx Adolescents.

OBJECTIVE: State-level policies that exclude immigrants, primarily undocumented, from public services and benefits have been found to have negative psychosocial impacts on Latinx adults, regardless of nativity. The effects of inclusionary policies-that is, extending public benefits to all immigrants-remain underexamined, as well as the impacts on adolescents. METHOD: We used data from the Youth Risk Behavior Survey from 2009 to 2019 to examine the association between 7 state-level inclusionary policies and bullying victimization, low mood, and suicidality among Latinx adolescents via 2-way fixed-effects log-binomial regression models. RESULTS: Banning the use of eVerify in employment was associated with decreased bullying victimization (prevalence ratio [PR] = 0.63, 95% CI: 0.53-0.74), low mood (PR = 0.87, 95% CI: 0.78-0.98), and suicidality (PR = 0.73, 95% CI: 0.62-0.86). Extending public health insurance coverage was associated with decreased bullying victimization (PR = 0.57, 95% CI: 0.49-0.67), and mandating Culturally and Linguistically Appropriate Services (CLAS) training for health care workers was associated with decreased low mood (PR = 0.79, 95% CI: 0.69-0.91). Extending in-state tuition to undocumented students was associated with increased bullying victimization (PR = 1.16, 95% CI: 1.04-1.30), and extending financial aid was associated with increased bullying victimization (PR = 1.54, 95% CI: 1.08-2.19), low mood (PR = 1.23, 95% CI: 1.08-1.40), and suicidality (PR = 1.38, 95% CI: 1.01-1.89). CONCLUSION: The relationships between inclusionary state-level policies and Latinx adolescent psychosocial outcomes were mixed. Although most inclusionary policies were associated with improved psychosocial outcomes, Latinx adolescents residing in states with inclusionary policies related to higher education had worse psychosocial outcomes. Results suggest the importance of elucidating the unintended consequences of well-intentioned policies and the importance of continued efforts to reduce anti-immigrant sentiment.

Causally interpretable meta-analysis: Clearly defined causal effects and two case studies.

Meta-analysis is commonly used to combine results from multiple clinical trials, but traditional meta-analysis methods do not refer explicitly to a population of individuals to whom the results apply and it is not clear how to use their results to assess a treatment's effect for a population of interest. We describe recently-introduced causally interpretable meta-analysis methods and apply their treatment effect estimators to two individual-participant data sets. These estimators transport estimated treatment effects from studies in the meta-analysis to a specified target population using the individuals' potentially effect-modifying covariates. We consider different regression and weighting methods within this approach and compare the results to traditional aggregated-data meta-analysis methods. In our applications, certain versions of the causally interpretable methods performed somewhat better than the traditional methods, but the latter generally did well. The causally interpretable methods offer the most promise when covariates modify treatment effects and our results suggest that traditional methods work well when there is little effect heterogeneity. The causally interpretable approach gives meta-analysis an appealing theoretical framework by relating an estimator directly to a specific population and lays a solid foundation for future developments.

Biobehavioral and affective stress responses during nicotine withdrawal: Influence of regular cannabis co-use.

BACKGROUND: Co-use of cannabis is increasing in nicotine users and presents additional challenges in addressing nicotine dependence. This study examined the links between regular co-use of cannabis and nicotine with biobehavioral and affective changes in response to stress during nicotine withdrawal and ad libitum use. METHODS: Participants (N = 79) who regularly used nicotine-only, cannabis-only, both substances, or neither substance were invited to attend two laboratory stress assessment sessions. For nicotine users, one session occurred during ad libitum nicotine use and one occurred after abstinence from nicotine. During the stress sessions, participants provided saliva samples for cortisol assay and completed measures of subjective states. Cardiovascular measures were collected during resting baseline, exposure to acute stressors, and a recovery rest period. RESULTS: Nicotine-only users had higher average cortisol levels in the second lab session (nicotine withdrawal) relative to the first lab session (ad libitum nicotine use). Compared to nicotine non-users, nicotine users reported less positive affect and exhibited attenuated cortisol and systolic blood pressure (BP) stress responses. Cannabis users exhibited exaggerated diastolic BP responses to stress compared to cannabis non-users, and co-users of nicotine and cannabis had higher levels of cannabis craving than cannabis-only users (p < .01). CONCLUSIONS: This study partially replicated earlier findings on the effects of chronic nicotine use and provided novel results regarding the influence of cannabis co-use on physiological and affective responses to stress in nicotine users during nicotine withdrawal.

Occurrence and Predictors of Postoperative Preauricular and Masticatory Muscle Pain Symptoms After Surgical Removal of Third Molars: A Single-Blind Randomized Controlled Trial Comparing Dental Assistants Supporting the Mandible and the Restful Jaw Device.

BACKGROUND: During third molar removal, the mandible is supported by a dental assistant (DA) to counter downward forces during surgery, and with sedation, to maintain airway patency. The Restful Jaw device (PEP Design; Saint Paul) provides this support instead of the DA. PURPOSE: This study compared the occurrence of postoperative preauricular and masticatory muscle pain symptoms (PMMPS) between the device and DAs providing mandibular support, using two outcome measures. Secondary aims identify predictors of outcome and providers' opinions of the device. STUDY DESIGN, SETTING, SAMPLE: In this multisite, single-blind, two-arm parallel randomized trial, participants without preoperative PMMPS had surgical removal of third molars, with sedation and bite blocks were randomly assigned to manual support or the device. EXPOSURE VARIABLE: The exposed group was randomly assigned to the device and the nonexposed group to manual support. MAIN OUTCOME VARIABLE(S): The primary outcome was patient-reported PMMPS. Two secondary outcomes were pain assessed with the temporomandibular disorder Pain Screener and providers' views on the device. Outcomes were assessed at 1-, 3-, and 6-month postsurgery. COVARIATES: The covariates are baseline demographics (eg, sex), clinical characteristics (eg, eruption status), and third molar surgeries. ANALYSES: For occurrence of pain, generalized estimating equations assessed differences between groups. Logistic regression analysis assessed predictors of pain at 1 month, per the Screener. The level for statistical significance was 5%. RESULTS: Enrollment was 86 and 83 participants in the device and DA groups, respectively. The average age was 20.8 years; the majority were female (65%) and Caucasian (66%). The retention rate was ≥95.9%. The groups did not differ significantly for occurrence of pain using the primary and secondary outcome measures at any follow-up (P ≥ .46). Fully impacted molars were associated with occurrence of pain (odds ratio = 3.44; 95% confidence interval 1.49-7.92; P = .004). CONCLUSION AND RELEVANCE: Occurrence of pain using the primary and secondary outcome measures did not differ significantly between groups at any follow-up and was associated with removal of fully impacted third molars. Four out of five surgeons reported wanting to use the device on a regular basis when performing this procedure in sedated patients.

Early Metabolic Measures Predict Long-term Insulin Independence in Recipients of Total Pancreatectomy and Islet Autotransplantation.

Background: Although diabetes after total pancreatectomy and islet autotransplantation (TP-IAT) is one of the biggest concerns for TP-IAT recipients and physicians, reliable prediction of post-TP-IAT glycemic control remains unestablished. This study was conducted to identify early predictors of insulin independence and goal glycemic control by hemoglobin A1c (HbA1c) ≤ 6.5% after TP-IAT. Methods: In this single-center, retrospective study, patients who underwent TP-IAT (n = 227) were reviewed for simple metabolic markers or surrogate indices of ß-cell function obtained 3 mo after TP-IAT as part of standard clinical testing. Long-term metabolic success was defined as (1) insulin independence and (2) HbA1c ≤ 6.5% 1, 3, and 5 y after TP-IAT. Single- and multivariate modeling used 3-mo markers to predict successful outcomes. Results: Of the 227 recipients, median age 31 y, 30% male, 1 y after TP-IAT insulin independence, and HbA1c ≤ 6.5% were present in 39.6% and 72.5%, respectively. In single-predictor analyses, most of the metabolic markers successfully discriminated between those attaining and not attaining metabolic goals. Using the best model selected by random forests analysis, we accurately predicted 1-y insulin independence and goal HbA1c control in 77.3% and 86.4% of the patients, respectively. A simpler "clinically feasible" model using only transplanted islet dose and BETA-2 score allowed easier prediction at a small accuracy loss (74.1% and 82.9%, respectively). Conclusions: Metabolic testing measures performed 3 mo after TP-IAT were highly associated with later diabetes outcomes and provided a reliable prediction model, giving valuable prognostic insight early after TP-IAT and help to identify recipients who require early intervention.

The impact of hurricane trauma and cultural stress on posttraumatic stress among hurricane Maria survivors relocated to the U.S. mainland.

OBJECTIVES: Following Hurricane Maria, scores of Puerto Rican "Maria migrants" fled the island with thousands permanently resettling on the United States (U.S.) mainland. Emerging evidence suggests that many Maria migrants are exposed to migration-related cultural stressors, including discrimination, negative context of reception, and language stress. The present study examines the associations of premigration hurricane trauma and postmigration cultural stress with posttraumatic stress disorder (PTSD) symptom severity and positive PTSD screens. METHOD: Participants were 319 adult (age 18+, 71% female) Puerto Rican Hurricane Maria survivors on the U.S. mainland. Data were collected virtually between August 2020 and October 2021. Participants completed Spanish-language measures of hurricane-related trauma, postmigration cultural stress exposure, PTSD symptoms, and positive screens. RESULTS: One in five (20.5%) Maria migrants reported PTSD scores in the range indicating a likely PTSD diagnosis (i.e., positive screen of 50+). Both hurricane trauma and migration-related cultural stressors independently predicted posttraumatic stress and positive PTSD screens. Additionally, controlling for the effect of hurricane trauma, discrimination and language stress were strongly linked with PTSD. Further, hurricane trauma and cultural stressors interact such that cultural stress predicts PTSD-positive screens at low-to-moderate levels of hurricane trauma exposure but not at high-to-very-high levels. CONCLUSION: Findings underscore the importance of providing mental health and other psychosocial supports to hurricane survivors and evacuees beyond the immediate aftermath of the disaster, and the need to consider both premigration trauma and postmigration experiences in terms of the mental health of crisis migrant populations.

Blood Levels of Environmental Heavy Metals are Associated with Poorer Iron Status in Ugandan Children: A Cross-Sectional Study.

BACKGROUND: Iron deficiency (ID) and environmental exposure to metals frequently co-occur among Ugandan children, but little is known about their associations, although iron and other divalent metals share the same intestinal absorption transporter, divalent metal transporter 1 (DMT1). OBJECTIVES: We examined associations between iron status and blood concentrations of lead, manganese (Mn), cobalt (Co), and cadmium, both singly and as a mixture. METHODS: We used data on sociodemographic status, iron biomarkers, and blood concentrations of heavy metals collected from a cross-sectional survey of 100 children aged 6-59 mo in Kampala, Uganda. We compared blood concentrations of metals in ID with iron-sufficient children. We examined associations between a metal mixture and iron biomarkers using multiple linear regression and weighted quintile sum regression. RESULTS: The median (interquartile range) blood Mn (µg/L) was higher in ID children defined by soluble transferrin receptor (sTfR) and ferritin (ID compared with iron-sufficient children): (sTfR [21.3 {15.1, 28.8}, 11.2 {8.6, 18.5}], ferritin [19.5 {15.0, 27.2}, 11.2 {8.8, 19.6}]; P < 0.001 for both). Similarly, the median (interquartile range) blood Co (µg/L) was higher in ID children by ferritin ([0.5 {0.4, 0.9}, 0.4 {0.3, 0.5}], P = 0.05). Based on the multiple linear regression results, higher blood Co and Mn were associated with poorer iron status (defined by all 4 iron indicators for Co and by sTfR for Mn). The weighted quintile sum regression result showed that higher blood concentrations of a metal mixture were associated with poorer iron status represented by sTfR, ferritin, and hepcidin, mainly driven by Co and Mn. CONCLUSIONS: Our study findings suggest that poorer iron status is associated with overall heavy metal burden, predominantly Co and Mn, among Ugandan children. Further prospective studies should confirm our primary findings and investigate the combined effects of coexposures to neurotoxicants on the neurodevelopment of young children.

Driving under the influence of cannabis and alcohol: Evidence from a national sample of young drivers.

OBJECTIVE: Driving under the influence (DUI) of psychoactive substances is an important public health and criminal justice issue, impacting the lives of millions of Americans. Although recent research provides up-to-date information regarding DUI among adults, there is a pressing need for research that focuses specifically on younger/underage drivers. We draw from a large, nationally-representative sample to provide up-to-date evidence as to the prevalence and key criminal justice, substance use, and behavioral health correlates of DUI of cannabis and alcohol among drivers ages 16 to 20 in the United States. METHODS: We used data from the 2020 and 2021 National Survey on Drug Use and Health (young drivers ages 16-20; N=12,863). All analyses-survey adjusted prevalence estimates, logistic regression-were conducted using Stata SE 17.0 and weighted to account for the study's stratified cluster sampling design. RESULTS: The prevalence of DUI-cannabis for the full sample-including those not endorsing past-year use-was 6.3%. Among youth endorsing past-year cannabis use, 24.5% reported DUI of cannabis. In the full sample and among cannabis users, DUI-cannabis risk was elevated among older and male youth. The prevalence of DUI-alcohol was 2.6% among all youth and 6.1% among youth reporting past-year alcohol consumption. CONCLUSIONS: Estimates indicate that more than one million young drivers each year are placing their lives and those of others at risk by operating motor vehicles after consuming cannabis and/or alcohol. Findings underscore the importance of prevention efforts targeting underaged cannabis and alcohol-impaired driving.

Islet graft function by mixed meal tolerance testing is sustained over 4 years in young children undergoing total pancreatectomy with islet autotransplantation.

Children with intractable chronic pancreatitis may require total pancreatectomy with islet autotransplantation (TPIAT) for pain relief. The IAT reduces the severity of post- pancreatectomy diabetes. We analyzed 635 mixed meal tolerance tests (MMTT) in 134 children undergoing TPIAT to determine whether superior survival of islet grafts explains higher rates of insulin independence previously reported in young children (n = 52, age 3-11 years) versus adolescents (n = 82, age 12-18 years). For MMTT, children consumed Boost HP and we sampled C-peptide and glucose repeatedly over 2 h. The trajectory of outcomes before and after TPIAT was compared between children and adolescents using data from pre-TPIAT and 3, 6 months, 1, 2, 3, and 4 years post-TPIAT and mixed linear models with a random effect for child. Cox regression was used to analyze time outcomes (e.g., time to first off insulin). Islet mass transplanted, measured as islet equivalents (IEQ), was higher in adolescents (p = .003) but IEQ/kg was higher in young children (p < .001) because of their lower weight. AUC C-peptide in young children increased somewhat over 4 years, but was stable in adolescents (p = .0013). AUC glucose increased more in adolescents over time post-TPIAT (p = .0024). Islet function by AUC C-peptide:AUC glucose ratio was better preserved in young children (p < .001). Adolescents were less likely to wean off insulin (hazard ratio .44 [95% CI .28, .69]). These data support an advantage of young age in islet graft survival after TPIAT. The greater likelihood of insulin independence in young children may be driven by better islet survival after transplant.

Telehealth for All? Assessing Remote Service Delivery for Latinx Immigrants.

The COVID-19 pandemic spurred a widespread shift to remotely delivered health services. Telehealth has shown promise in making healthcare more accessible. Little research has looked at the effects of this change on access to healthcare for Latinx immigrants. This qualitative study explored the shift to remote services during the COVID-19 pandemic in a new immigrant destination. Authors interviewed 23 service providers to assess if telehealth increased access to healthcare for Latinx immigrants. Results showed that telehealth improved access to services overall. Still, barriers to care remained. Immigrants experienced (a) limited access to technology and low digital literacy, (b) lack of privacy during the provision of services, (c) inability to utilize certain digital platforms due to confidentiality regulations, and (d) decreased quality of services. Findings suggest that telehealth is a promising modality to decrease healthcare disparities, but providers need to thoughtfully address barriers unique to Latinx immigrants to ensure their full participation.

A Controlled Study of Biopsychosocial Differences Observed in Masticatory Myalgia With and Without Pain Referral.

AIMS: To assess differences in biopsychosocial factors between participants with masticatory myofascial pain with referral (MFPwR), with myalgia without referral (Mw/oR), and community controls without TMDs. METHODS: Study participants were diagnosed with MFPwR (n = 196), Mw/oR (n = 299), or as a non-TMD community control (n = 87) by two calibrated examiners at each of three study sites. Pain chronicity, pain on palpation of masticatory muscle sites, and pressure pain thresholds (PPT) at 12 masticatory muscle, 2 trigeminal, and 2 nontrigeminal control sites were recorded. Psychosocial factors assessed included anxiety, depression, and nonspecific physical symptoms (Symptom Checklist-90 Revised); stress (Perceived Stress Scale); and health-related quality of life (Short Form Health Survey). Comparisons among the three groups were adjusted for age, sex, race, education, and income using multivariable linear regression. The significance threshold was set at P = .017 (.05 / 3) for subsequent pairwise comparisons. RESULTS: Compared to the Mw/oR group, the MFPwR group had significantly greater pain chronicity, number of painful muscle sites, anxiety, depression, nonspecific physical symptoms, and impaired physical health (P < .017). The MFPwR group also had significantly lower PPTs for masticatory sites (P < .017). Both muscle pain groups differed significantly from the non-TMD community control group for all outcome measures (P < .017). CONCLUSION: These findings support the clinical utility of separating MFPwR from Mw/oR. Patients with MFPwR are more complex from a biopsychosocial perspective than Mw/oR patients, which likely affects prognosis and supports consideration of these factors in case management.

Ethnoracial differences in workplace drug testing and policies on positive drug tests in the United States.

BACKGROUND: Drug testing is widely implemented as a work-based prevention strategy for employee substance use. However, it has raised concerns about its potential use as a punitive measure in the workplace where racialized/ethnic workers are over-represented. This study examines the rates of exposure to workplace drug testing among ethnoracial workers in the United States and the potential differences in the employers' responses to positive test results. METHODS: A nationally-representative sample of 121,988 employed adults was examined using the 2015-2019 National Survey on Drug Use and Health data. The rates of exposure to workplace drug testing were estimated separately for ethnoracial workers. Then we used multinomial logistic regression to test differences in employers' responses to the first positive drug test results across ethnoracial subgroups. RESULTS: Since 2002, Black workers reported 15-20% points higher rates of having a workplace drug testing policy than Hispanic or White workers. When tested positive for drug use, Black and Hispanic workers were more likely to be fired than White workers. When tested positive, Black workers were more likely to be referred to treatment/counseling services while Hispanic workers were less likely to be referred compared to White workers. CONCLUSION: Black workers' disproportionate exposure to drug testing and punitive responses in the workplace may potentially place individuals with substance use problems out of the workforce, limiting their access to treatment/other resources available via their workplaces. Also, Hispanic workers' limited accessibility to treatment and counseling services when tested positive for drug use requires attention to address unmet needs.

Tooth-level predictors of tooth loss and exposed bone after radiation therapy for head and neck cancer.

BACKGROUND: The objective of this study was to identify tooth-level risk factors for use during preradiation dental care management to predict risk of tooth failure (tooth lost or declared hopeless) and exposed bone after radiation therapy (RT) for head and neck cancer (HNC). METHODS: The authors conducted a prospective observational multicenter cohort study of 572 patients receiving RT for HNC. Participants were examined by calibrated examiners before RT and then every 6 months until 2 years after RT. Analyses considered time to tooth failure and chance of exposed bone at a tooth location. RESULTS: The following pre-RT characteristics predicted tooth failure within 2 years after RT: hopeless teeth not extracted pre-RT (hazard ratio [HR], 17.1; P < .0001), untreated caries (HR, 5.0; P < .0001), periodontal pocket 6 mm or greater (HR, 3.4; P = .001) or equaling 5 mm (HR, 2.2; P = .006), recession over 2 mm (HR, 2.8; P = .002), furcation score of 2 (HR, 3.3; P = .003), and any mobility (HR, 2.2; P = .008). The following pre-RT characteristics predicted occurrence of exposed bone at a tooth location: hopeless teeth not extracted before RT (risk ratio [RR], 18.7; P = .0002) and pocket depth 6 mm or greater (RR, 5.4; P = .003) or equaling 5 mm (RR, 4.7; P = .016). Participants with exposed bone at the site of a pre-RT dental extraction averaged 19.6 days between extraction and start of RT compared with 26.2 days for participants without exposed bone (P = .21). CONCLUSIONS: Individual teeth with the risk factors identified in this study should be considered for extraction before RT for HNC, with adequate healing time before start of RT. PRACTICAL IMPLICATIONS: The findings of this trial will facilitate evidence-based dental management of the care of patients receiving RT for HNC. This clinical trial was registered at Clinicaltrials.gov. The registration number is NCT02057510.

Sexual minorities and substance use treatment utilization: New evidence from a national sample.

INTRODUCTION: Minority stress theory suggests that sexual minorities would be, on average, less likely than heterosexual individuals to seek out substance use treatment (due to concerns of stigma and rejection). However, prior research on the subject is mixed, and largely dated. In light of historic increases in societal acceptance and legal protections for sexual minorities, the field needs an up-to-date assessment of treatment utilization among this population. METHODS: This study used data from the 2015-2019 National Survey on Drug Use and Health to examine the association between key independent variables (sexual identity, gender) and substance use treatment utilization using binary logistic regression. We conducted analyses using a sample of adults with a past-year substance use disorder (N = 21,926). RESULTS: Controlling for demographic factors, with heterosexual individuals as the comparison group, gay/lesbian individuals (AOR = 2.12, CI = 1.19-3.77) were significantly more likely and bisexual individuals (AOR = 0.49, CI = 0.24-1.00) significantly less likely to report treatment utilization. Bisexual individuals were also less likely than gay/lesbian individuals to report treatment utilization (AOR = 0.10, CI = 0.05-0.23). Interaction tests examining sexual orientation and gender showed no difference in treatment utilization between gay men and lesbian women, and revealed that bisexual identity was associated with decreased likelihood of treatment utilization for men (p = .004) but not for women. CONCLUSION: Sexual orientation, particularly in the context of social identity, plays a significant role in substance use treatment utilization. Bisexual men face unique barriers to treatment, which is concerning given the high rates of substance use among this and other sexual minority populations.

Impact of School Shootings on Adolescent School Safety, 2009-2019.

Objectives. To examine the impact of school shootings on indicators of adolescent school safety in the United States. Methods. We linked 2009-2019 Youth Risk Behavior Survey data on 211 236 adolescents aged 14 to 18 years from 24 school districts with data on high school shootings from the Center for Homeland Defense and Security. We conducted 2-way fixed-effects logistic regression models to assess the impact of shootings on self-report of 3 indicators of school safety: avoiding school because of feeling unsafe, carrying a weapon at school, and being threatened or injured with a weapon at school. Results. High school shootings were associated with adolescents having 20% greater odds of avoiding school because of feeling unsafe (adjusted odd ratio [AOR] = 1.20; 95% confidence interval [CI] = 1.11, 1.29) than those who had not. Findings were slightly attenuated in sensitivity analyses that tested exposure to shootings at any school in the district or state. High school shootings were associated with a statistically nonsignificant (P = .08) elevated risk of carrying a weapon at school (AOR = 1.11; 95% CI = 0.99, 1.25). Conclusions. The negative ramifications of school shootings extend far beyond the event itself to adolescents' concerns about school safety. (Am J Public Health. 2023;113(4):438-441. https://doi.org/10.2105/AJPH.2022.307206).
