RESUMEN
This study explored lived experiences of LGBTQIA+ survivors of intimate partner violence (IPV). Seven participants completed a one-on-one, in-depth interview to share their experiences of IPV and any internal or external factors that influenced whether they sought support services or reported victimization. Thematic analysis revealed four overarching themes: (a) health complications, (b) coping mechanisms, (c) barriers to seeking professional help, and (d) suggestions for professionals. Results contribute insight into internal and external barriers LGBTQIA+ IPV survivors face when accessing support services and outline practical approaches for professionals providing support to LGBTQIA+ IPV survivors.

Sexual violence victimization among adolescents, specifically sexual minority youth, is a significant public health concern. The purpose of this study was to compare sexual violence victimization rates among sexual minority and heterosexual youth using nationally representative data from the 2019 Youth Risk Behavioral Surveillance System. Results indicated that lesbian, gay, bisexual, and questioning youth were significantly more likely than heterosexual youth (p < .05) to experience sexual violence (22.3% vs. 9.1%), sexual dating violence (16.3% vs. 6.4%), and forced sexual intercourse (17.6% vs. 5.9%). Among sexual minority youth, female participants were more likely than male participants (p < .05) to experience sexual violence (23.5% vs. 18.0%), sexual dating violence (17.2% vs. 11.6%), and forced sexual intercourse (19.0% vs. 13.1%). This study identified varying rates of sexual violence victimization among a national sample of youth while examining the differences between heterosexual and sexual minority communities. The additional behavioral risks experienced by sexual minority youth should be further researched to determine impact on overall quality of life and to help guide health education intervention development.

BACKGROUND: Cardiovascular implantable electronic devices (CIEDs) have historically restricted the use of magnetic resonance imaging (MRI) due to the potential clinical and configurational risks associated with electromagnetic interference. In this study, the authors investigated the impact of MRI on the functional integrity of non-conditional CIEDs and their clinical correlates. METHODS: In this prospective, observational single-center study, we enrolled patients undergoing MRI over a 5-year period. Prior to assessing the impact of MRI on CIEDs, we performed interrogations in sequential duplication to assess the intrinsic variability of devices. Subsequently, we performed interrogations immediately after MRI, and monitored changes in device parameters and clinical events. RESULTS: We completed 492 MRI studies, 58% in patients with permanent pacemakers (PPMs) and 42% with implantable cardioverter defibrillators (ICDs). Subsequent MRI exposures occurred in 15% encounters. Accounting for intrinsic variability in CIED leads, there were no significant changes in RA, RV, or LV parameters after MRI, regardless of the region imaged (thoracic vs. non-thoracic), type of CIED (PPMs vs. ICDs) and among those with serial MRIs. When ranked for % change pre- to post-MRI, the majority of RA, RV, and LV metrics for thresholds, sensing, and impedance conformed to ≤20% change from baseline. No significant clinical adverse cardiac events or effect on device microcircuitry occurred during the study. CONCLUSION: Incorporating a novel reproducibility tactic, there were neither clinically meaningful device parameter changes nor adverse clinical events during or following MRIs, suggesting the effects of MRI on non-conditional CIED integrity are far less than previously perceived.

Cardiac imaging is the cornerstone of defining the etiology, quantification, and management of mitral regurgitation (MR). This continues to be even more so the case with emerging transcatheter techniques to manage MR. Transthoracic echocardiography remains the first-line imaging modality to assess MR but has limitations. Cardiac MRI(CMR) provides the advantages of quantitative nonvisual estimation, 3D volumetric data, late gadolinium, T1, and extracellular volume measurements to comprehensively assess mitral valvular pathology, cardiac remodeling, and the prognostic impact of therapies. This review describes the superiority, technical aspects and growing evidence behind CMR, and lays the roadmap for the future of CMR in MR.

BACKGROUND: Treatments for unicameral bone cysts (UBCs) have high documented failure rates (27% to 63%) because of recurrence or persistence of the cyst, similar to nonoperative management. Recent evidence suggests that filling of the defect with a synthetic bone graft substitute (SBGS) supports the weakened cortex and promotes new bone growth. A calcium sulfate, brushite, calcium phosphate, composite graft material (PRODENSE, Wright Medical, Memphis, TN) has been evaluated as a substitute for autogenous or allogenous graft in animal and human studies. The purpose of this study was to compare the rates of revision surgery in patients treated for UBCs with an SBGS compared with historical treatments with allograft or autologous bone marrow aspirate. METHODS: The authors reviewed 27 of 33 patients (age, 6 months to 21 years) an average of 121 months (range, 32 to 228) after filling of a UBC with an injection of SBGS (n=18) versus allograft or autologous bone marrow aspirate (n=9) between June 2008 and December 2017. Six patients with no follow-up were excluded. Groups did not differ in age at surgery, sex (19/27 male), history of pathologic fracture (22/27), or previous treatments (11/27). The primary outcome was the rate of revision surgery. Secondary outcomes included revision surgery-free survival as evaluated by the log-rank test, rate of postoperative fracture, persistent cysts, continued pain, and/or growth disturbance at the final follow-up. RESULTS: Seven of 9 patients treated with allograft or autograft underwent revision surgery for postoperative pathologic fracture (n=2) or resorption of the graft (n=5) compared with 2 of 18 patients injected with the SBGS, both treated for graft resorption. The use of SBGS was associated with a decreased need for revision surgery over all time periods (hazard ratio, 0.14; 95% confidence interval, 0.03-0.05). There was no significant difference between postoperative fracture (2/18 vs. 2/9), persistent cyst (7/18 vs. 5/9), pain (0/18 vs. 2/9), or growth disturbance (1/18 vs. 3/9). CONCLUSIONS: Treatment of UBCs with SBGS may decrease reoperation rates. Initial radiographic appearance after SBGS treatment shows solid structural support, followed by new bone formation. This appearance may lead to a less aggressive approach in considering revision surgery. LEVEL OF EVIDENCE: Level III-retrospective comparative study investigating the results of treatment.

Sexual dating violence is associated with several risky health behaviors among adolescents. This study explored the associations between school-based violence, risky health behaviors, and sexual dating violence victimization among U.S. high school students using the 2017 Youth Behavior Risk Survey data. Results indicate a statistically significant correlation (p < .05) between sexual dating violence, sex, sexual identity, and various risky behaviors including bullying, electronic bullying, alcohol use, and physical fighting. These additional behavioral risks experienced by sexual dating violence victims should be further researched to determine impact on overall quality of life and to help guide health education intervention development.

Studies indicate that tobacco use among lesbian, gay, bisexual, transgender, or queer (LGBTQ) community members is consistently higher than the general population. The Last Drag is a tobacco cessation program developed and implemented in 1991 in San Francisco, California, that has shown promise in assisting LGBTQ members with tobacco cessation. This article describes the practical challenges of adapting The Last Drag to be implemented in a southcentral Texas community. Primary challenges included short time line to expected implementation, issues with culturally insensitive language, and barriers to participant recruitment. Acknowledging and overcoming these challenges can assist public health educators who are addressing tobacco cessation in LGBTQ populations.

The purpose of this study was to evaluate the mediation effect of sexting, and taking sexually suggestive photos on religiosity and hooking-up with three separate sexual outcomes. A web-based survey examined the relationship between religiosity and the three hooking-up outcomes among students reporting sexting or taking a sexually suggestive photo in the last 30 days (n = 231). Sexting, as well as taking sexually suggestive photos mediated the relationship between religiosity and hooking-up among females. Sexting may be initiated by females as a way to engage in a nonphysical sexual interaction, which ultimately predisposes them to a physical sexual outcome.

Air monitoring is desirable in many places to understand dynamic pollution trends and sources and improve knowledge of population exposure. While highly miniaturized low cost sensor technology is quickly evolving, there is also a need for the advancement of mid-tier systems that are closer to reference-grade technologies in their longevity and performance, but also feature compactness that requires less significant infrastructure. This project evaluated the performance of a prototype solar-powered air monitoring system known as a Village Green Project (VGP) system with wireless data transmission that was deployed on a school rooftop in Hong Kong and operated for over one year. The system provided highly time-resolved and long-term data utilizing mid-tier cost ozone, PM2.5 and meteorological instruments. It operated with very minimal maintenance but shading by a nearby building reduced solar radiation, thus battery run time, over the 16-months measurement period, approximately 330,000 1-min observations were recorded (data completeness of ~62%). The monitoring data were evaluated by comparison with a nearby Hong Kong Environment Protection Department (EPD) station and exhibited good performance for 1-h resolution (R 2 = 0.74 for PM2.5 and R 2 = 0.76 for ozone). Furthermore as a demonstration, a nonparametric regression (NPR) model was applied for identifying the location of pollution source, combining air pollution and meteorological measurements. In addition, based on the high time-resolution wind data, local-scale back-trajectories were calculated as an input for receptor-oriented Nonparametric Trajectory Analysis (NTA) model. The combination of the VGP air monitoring system and NTA model identified apparent local sources in urban area. The demonstration was largely successful and operational improvements are clearly suggested to insure better siting and configurations to insure adequate power and air flow.
RESUMEN
BACKGROUND: The preoperative workup of orthotopic liver transplantation (OLT) patients is practically complex given the need for multiple imaging modalities. We recently demonstrated in our proof-of-concept study the value of a one-stop-shop approach using cardiovascular MRI (CMR) to address this complex problem. However, this approach requires further validation in a larger cohort, as detection of hepatocellular carcinoma (HCC) as well as cardiovascular risk assessment is critically important in these patients. We hypothesized that coronary risk assessment and HCC detectability is acceptable using the one-stop-shop CMR approach. METHODS: In this observational study, patients underwent CMRI evaluation including cardiac function, stress CMR, thoracoabdominal MRA, and abdominal MRI on a standard MRI scanner in one examination. RESULTS: Over 8 years, 252 OLT candidates underwent evaluation in the cardiac MRI suit. The completion rates for each segment of the CMR examination were 99% for function, 95% completed stress CMR, 93% completed LGE for viability, 85% for liver MRI, and 87% for MRA. A negative CMR stress examination had 100% CAD event-free survival at 12 months. A total of 63 (29%) patients proceeded to OLT. Explant pathology confirmed detection/exclusion of HCC. CONCLUSIONS: This study further defines the population suitable for the one-stop-shop CMR concept for preop evaluation of OLT candidates providing a road map for integrated testing in this complex patient population for evaluation of cardiac risk and detection of HCC lesions.

In diagnosing cardiac and paracardiac masses, cardiac MRI (CMR) has gained acceptance as the gold standard. CMR has been observed to be superior to echocardiography in characterizing soft-tissue structures and, specifically, in classifying cardiac masses. The aim of our study was to evaluate the association between mortality and cardiac or paracardiac masses initially identified by echocardiography (ECHO) and confirmed by CMR. Between January 2002 and August 2007, a total of 158 patients underwent both ECHO and CMR for the evaluation of cardiac masses that were equivocal or undefined by ECHO. The primary study endpoints were 5-year all-cause mortality and 5-year cardiac mortality. Causes of death as of April 1, 2015 were obtained from medical records or the National Death Index. Patients were analyzed according to mass type determined by CMR using the Kruskal-Wallis test, Kaplan-Meier curves, and the log-rank test. Over a mean duration of follow-up of 10.4 ± 2.9 years (range: 0.01-12 years) post-CMR, the overall all-cause mortality rate was 25.9% (41/158). Median age at death was 76 years and there were 21 females (51.2%). Mortality rates in the different classifications of cardiac masses by CMR were as follows: 20% (1/5) in patients with a Nondiagnostic CMR; 20% (1/5) in Other Diagnoses; 17.9% (7/39) in No Masses (includes Normal Anatomical Variants); 16.7% (3/18) in Benign Masses; 23.8% (15/63) in Fat; 50% (5/10) in Thrombus; and 61.5% (8/13) in Malignant Mass. The mean survival time in patients with No Mass (n = 39) was not significantly longer than patients with any type of cardiac mass (n = 114) (P = .16). No significant difference was found in age at death between patients when grouped by CMR classification (P = .40). However, among CMR-confirmed masses, there were some significant differences by mass classification type (P = .006). During the follow-up period, 26% (41/158) of patients died and 22% (9/41) of the deaths were cardiovascular related; there was no significant difference in mean survival times with respect to cause of mortality (P = .23). In patients with cardiac masses, dually confirmed by ECHO and CMR, significant differences in survival time were observed based upon CMR classified type of mass while CMR was instrumental in obviating invasive biopsy.

The purpose of this study was to examine alcohol and tobacco access points among a sample of rural and urban youth. Through collaboration with four regional school districts, a local drug prevention coalition administered a survey to a sample of 445 youth representing 30 different communities in a central U.S. region. The survey items included demographics, 30-day use measures, and questions about points-of-access for alcohol and tobacco. Results showed no differences among points-of-access between urban and rural youth. Ability to obtain alcohol from family, peers, other non-peer youth, and other non-family adults (P < 0.05) were each statistically significant predictors of 30-day alcohol use. Ability to obtain tobacco from family, peers, other non-peer youth, other non-family adults, and self-purchase (P < 0.05) were statistically significant predictors of 30-day tobacco use. Access through peers was the strongest predictor for both 30-day alcohol and tobacco use. Determining the primary social points-of-access youth use to obtain alcohol and tobacco can assist in the development of appropriate community-level prevention strategies and policies.

Context ⢠In the United States in 2007, approximately 38% of adults, or 4 in 10, used some form of complementary and alternative medicine (CAM). An area in which little is known is the personal integration of CAM therapies by those individuals seeking to improve athletic performance. Objectives ⢠The study intended to assess the use of integrative care by adult athletes in the United States as well as their satisfaction with it, as reported in the 2012 National Health Interview Survey (NHIS). Design ⢠A secondary analysis of the data from the Adult Alternative Health/Complementary Medicine file of the 2012 NHIS was performed. SETTING: The analysis was performed at the Research Institute of Parker University (Dallas, TX, USA). Participants ⢠The NHIS survey was a representative sample of Americans, with more than 30 000 respondents. Outcome Measures ⢠National population estimates were generated for all related variables. The study assessed the likelihood that a respondent who reported use of a specific complementary and integrative therapy as their first top therapeutic modality to enhance sport or athletic performance had perceived it helpful compared with those who used it for other non-sport-related reasons. Results ⢠Complementary and integrative therapies were used by more than 14 million adults (20.5%) to improve athletic performance, with 97.6% of them perceiving therapies as helpful. The most used therapies were yoga, herbal supplements, manipulation, and massage. The median age of those reporting specific use to improve athletic performance was slightly less than 38 y, and women were almost 3 times as likely as men to report therapies as helpful. Conclusions ⢠Complementary and integrative therapies were used for improvement of athletic performance by respondents of the 2012 NHIS, with high satisfaction among users. Future research could evaluate athletic-specific use, adverse effects, physiological mechanisms that may exist for the modalities, and ways to integrate these methods better with traditional medical care.

BACKGROUND: About 30% of high school students use energy drinks. Alcohol mixed with energy drinks (AmED) has been associated with higher rates of risky driving among college students. OBJECTIVES: The purpose of this study was to: (a) examine AmED-use in a sample of high school students and (b) to specifically investigate differences in risky driving behaviors between 12th grade students who engaged in AmED-use and those who consumed alcohol only. METHODS: Differences in risky driving behaviors were investigated by utilizing secondary data analyses of nationally representative data from the Monitoring the Future Study (N = 1305). RESULTS: 12th grade AmED users were significantly more likely to be in a motor vehicle accident (p <.001) and receive a ticket for a traffic violation (p <.05). Additionally, 12th grade AmED users were significantly less likely to wear a seatbelt as a driver or passenger (p <.001). Conclusions/Importance: Although this study does not link risky driving behaviors to specific drinking events, it does indicate a relationship between AmED-use and high-risk driving. Because traffic accidents are the highest cause of mortality among U.S. teenagers, drug education efforts to reduce high-risk driving behaviors should include information on the decision-making and synergistic effects of energy drinks when mixed with alcohol.

BACKGROUND AND OBJECTIVES: Approximately 30% of high school students use energy drinks. Alcohol use and alcohol mixed with energy drink use (AmED) is associated with risky behavior, including non-medical prescription stimulant use. We assessed alcohol-only, AmED and non-medical prescription stimulant use among 12th grade students in the U.S. using a nationally representative secondary data from the 2012 Monitoring the Future Study. METHODS: Wilcoxon-Mann-Whitney tests and logistic regression analyses were used to determine differences in non-medical prescription stimulant use by students who used alcohol-only versus AmED and to identify covariates of non-medical prescription stimulant use. Pearson-product moment coefficients were used to determine strength of variable relationships. RESULTS: Significant differences were found in frequency of Ritalin (p < .001, Cohen's d = .23) and Adderall (p < .001, Cohen's d = .32) use between alcohol-only students and AmED students. Greater frequency of AmED use was also associated with greater frequency of Ritalin use (r = .293, p < .001) and Adderall use (r = .353, p < .001). Males (b = .138, OR = 1.148) were more likely to use prescription stimulants non-medically than females. DISCUSSION AND CONCLUSIONS: This study highlights the need to better understand influences on non-medical prescription stimulant, energy drink and AmED use, as the combined effects of stimulants contained in energy drinks and the depressant effects of alcohol appear to be associated with increased non-medical prescription stimulant use. SCIENTIFIC SIGNIFICANCE: Research on the influential factors related to energy drinks, alcohol, and non-medical prescription stimulants will help practitioners to more appropriately design prevention and intervention strategies addressing these high-risk behaviors.

BACKGROUND: Mold exposures have been linked to the development and exacerbation of asthma. The purpose of this study was to determine whether the Environmental Relative Moldiness Index (ERMI) metric, developed to quantify mold exposures in homes, might be applied to evaluating the mold contamination in schools. METHODS: Settled dust samples (n = 10) were collected on each level of a water-damaged school in Springfield, Massachusetts and two samples per level in five Idaho schools. Each dust sample was analyzed for the 36 molds that make up the ERMI. The concentration of 2.5-µm particulate matter (PM2.5 ) was measured in each school at two locations during the spring of 2013. RESULTS: The average ERMI value in the Springfield school, 15.51, was significantly greater (p < 0.001) than the average ERMI value, -2.87, in the Idaho schools. Ten of the twenty-six Group 1 molds, which are associated with water-damaged environments, were in significantly greater concentrations in the Springfield school. The populations of Group 2 molds, which are common indoors even without water damage, were essentially the same in Springfield and Idaho schools. The average PM2.5 concentration in the Springfield and Idaho schools was 11.6 and 3.4 µg/m(3) , respectively. CONCLUSIONS: The ERMI scale might be useful in comparing the relative mold contamination in schools.

Continuous, long-term, and time-resolved measurement of outdoor air pollution has been limited by logistical hurdles and resource constraints. Measuring air pollution in more places is desired to address community concerns regarding local air quality impacts related to proximate sources, to provide data in areas lacking regional air monitoring altogether, or to support environmental awareness and education. This study integrated commercially available technologies to create the Village Green Project (VGP), a durable, solar-powered air monitoring park bench that measures real-time ozone, PM2.5, and meteorological parameters. The data are wirelessly transmitted via cellular modem to a server, where automated quality checks take place before data are provided to the public nearly instantaneously. Over 5500 h of data were successfully collected during the first ten months of pilot testing in Durham, North Carolina, with about 13 days (5.5%) of downtime because of low battery power. Additional data loss (4-14% depending on the measurement) was caused by infrequent wireless communication interruptions and instrument maintenance. The 94.5% operational time via solar power was within 1.5% of engineering calculations using historical solar data for the location. The performance of the VGP was evaluated by comparing the data to nearby air monitoring stations operating federal equivalent methods (FEM), which exhibited good agreement with the nearest benchmark FEMs for hourly ozone (r(2) = 0.79) and PM2.5 (r(2) = 0.76).

Air pollution health studies of fine particulate matter (diameter ≤2.5 µm, PM2.5) often use outdoor concentrations as exposure surrogates. Failure to account for variability of indoor infiltration of ambient PM2.5 and time indoors can induce exposure errors. We developed and evaluated an exposure model for individuals (EMI), which predicts five tiers of individual-level exposure metrics for ambient PM2.5 using outdoor concentrations, questionnaires, weather, and time-location information. We linked a mechanistic air exchange rate (AER) model to a mass-balance PM2.5 infiltration model to predict residential AER (Tier 1), infiltration factors (Tier 2), indoor concentrations (Tier 3), personal exposure factors (Tier 4), and personal exposures (Tier 5) for ambient PM2.5. Using cross-validation, individual predictions were compared to 591 daily measurements from 31 homes (Tiers 1-3) and participants (Tiers 4-5) in central North Carolina. Median absolute differences were 39% (0.17 h(-1)) for Tier 1, 18% (0.10) for Tier 2, 20% (2.0 µg/m(3)) for Tier 3, 18% (0.10) for Tier 4, and 20% (1.8 µg/m(3)) for Tier 5. The capability of EMI could help reduce the uncertainty of ambient PM2.5 exposure metrics used in health studies.

BACKGROUND: The combined-use of alcohol and energy drinks is an emerging public health issue. This investigation examined differences in drinking and driving behaviors among combined-users (CU) and participants who consumed alcohol-only (AO). OBJECTIVES: This study was specifically designed to investigate potential differences in drinker's perceptions of (a) what it means to them to drive over the .08 Blood Alcohol Content (BAC) driving limit and (b) what it means to drive after knowing they have had too much to drink to drive safely. METHODS: College students (N = 355) were surveyed to assess differences in drinking and driving-related behaviors between the AO (n = 174) and CU (n = 107) groups. RESULTS: CU were more likely than AO to drive over the .08 BAC driving limit (53% vs. 38%; p = .009) and after knowing they were too drunk to drive (57% vs. 44%; p = .025). CU were also more likely (56% vs. 35%; p = .000) to ride with an intoxicated driver while knowing it was unsafe. Conclusions/Importance: Combined-users are more likely to drive after drinking, drive while knowingly drunk, and participate in other high-risk behaviors such as heavy drinking that increase the potential for injury. Public policy makers and health professionals should focus prevention efforts to reduce high-risk combined-use behavior.

BACKGROUND: The purpose of this study was to examine energy drink usage patterns and to investigate the relationship between energy drink use and illicit use of prescription stimulants among college students. METHODS: A sample of 605 undergraduate and graduate students (mean age±SD: 21.96±4.216) from a large midwestern university voluntarily participated in the study. RESULTS: Of the participants, 48.9% (n=296) reported using energy drinks in the past 30 days, whereas 25.3% (n=153) reported using prescription stimulant drugs in the past 30 days. Among prescription stimulant users without a valid medical prescription, Mann-Whitney U tests and logistic regression analysis revealed that the frequency of energy drink consumption was a significant predictor of illicit prescription stimulant use, with the odds for use increasing by 14% with each additional day of energy drink use (odds ratio for using=1.143, P≤.001). Analyses revealed statistically significant differences (P<.05) between prescription stimulant users and nonusers for all energy drink use variables, with the strongest predictors of prescription stimulant use being the number of days using energy drinks in the past 30 days and number of energy drink binges in the past 30 days. CONCLUSIONS: Results indicate that the frequency of energy drink use was a significant predictor of the illicit use of prescription stimulants.
