Methods: Patients who underwent an ACL reconstruction by a single surgeon between January 2012 and June 2020 were identified by an institutional query using Current Procedural Terminology codes. Patients were included if they (1) underwent a primary ACL reconstruction and (2) had a minimum of 2 years' follow-up. Data were retrospectively collected regarding demographics, surgical details, visual analog scale (VAS) scores, and 12-item short form survey (SF-12) scores. Resilience scores were obtained via the Brief Resilience Scale questionnaire. Stratification into low (LR), normal (NR), and high resilience (HR) was based on standard deviation from mean Brief Resilience Scale score to determine differences in PROMS between groups. Results: One-hundred eightyseven patients were identified by the institutional query. Of the 187 patients, 180 met inclusion criteria. Seven patients underwent revision ACL reconstruction and were excluded from the study. One-hundred three patients (57.2%) completed the postoperative questionnaire and were included. Patients in the NR group and HR group had significantly greater postoperative SF-12 scores (P < .001) and lower postoperative VAS pain scores (P < .001) when compared with those of the LR group. This trend was again shown with breakdown of the SF-12 into physical and mental aspects, each of which were significantly greater in either the NR group or HR group when compared with the LR group (P < .001). Overall, 97.9% and 99.0% of patients had changes in their SF-12 total and VAS pain scores respectively that exceeded the minimal clinically important difference for the cohort. Conclusions: Patients with lower resilience scores have worse PROMs and increased pain than patients with greater resilience at a minimum of 2-year follow-up after ACL reconstruction. Level of Evidence: Level IV, prognostic case series.

This research estimates whether the association between bullying victimization and substance use is significantly greater among female adolescents. Using R software and the national Youth Risk Behavior Survey (2011, 2013, 2014, and 2017), interactions were estimated to determine the association between self-reported school or electronic bullying victimization and previous 30-day alcohol use, binge drinking, marijuana use, cigarette smoking, and electronic vaping product use. Bullying victimization was significantly associated with each of the substance use variables, Effects were significantly greater in female students. Efforts should be put in place in schools and communities to reduce bullying, mitigate the harmful effects of this form of victimization, and reduce illicit substance use.

Data were collected in early January 2013 by a telephone survey of a nationally representative sample of adults in the US. The data collection was sponsored by the Pew Foundation and made available for this research. Younger smartphone owners were significantly more likely to use their cell-phones to ask friends or family for product advice, to read product reviews online, and to engage in online price comparison while shopping. Women were significantly more likely than men to use their cell phone to acquire word-of-mouth product information from family and friends, but this gender effect was primarily observed among adults between 18-49 years. College education and household income were each significantly related to the use of cellphones in store to acquire purchase-related information. The results also suggest that firms need to adapt to the growing use of mobile phones to assist with in-store purchase decisions.

As such, this research examines specific elements of this process-the relationship between race, ethnicity, and consumer use of mobile coupons and digital barcodes to facilitate purchase decisions. Data were collected by telephone survey of a nationally representative sample of US adults. Results indicate minority (Non-White) adults are more likely than White adults to use their mobile phone in-store to purchase products with mobile coupons and to scan barcodes for product information. Individuals who use both social media and who own tablets or E-readers are more likely to use mobile phones to scan barcodes for product information. Those who use social media are more likely to use in-store mobile coupons. Shoppers with a household income greater than $75,000 are more likely to use mobile phone coupons. Findings indicate firms can further target consumers based on digital device ownership, social media habits, race and ethnicity, and income. Implications concerning in-store mobile coupons, digital barcodes, and targeting minority consumers are addressed. .

The data was adjusted through the use of sampling weights to estimate for general population parameters. The collected data examined online flirting, use of dating websites, and the use of dating apps. Findings suggest women between the ages of 18-34 years are just as likely as men to signal their romantic interest by engaging in online flirtation. In addition, women ages 50 years or older are less likely than men to signal their romantic interest by engaging in online flirtation. Also, adults ages 50 years or more who flirt online are more likely to use an online dating website or app. Findings concerning Generation X are also discussed. Marketing implications include a concentration on “flirting-focused” options, especially in relation to free trials, promotional offers, and marketing tactics for digital dating services. St...

A descriptive, cross-sectional design was employed. A convenience sample of 88 low-income or ethnic-minority mothers aged 21 to 45 completed a depression scale, demographic data sheet, and responded to an open-ended question. Content analysis, descriptive, and inferential statistics was used for data analysis. Exactly 42.5% of mothers reported high depressive symptoms (>16). Lower income levels ( r = .342, p = .01) and head-of-household status ( r = .220, p = .04) were significantly associated with higher depressive symptoms. Those who used social support coping had lower depressive symptoms than those who did not ( t = 2.50, p = .014). Those using emotion-focused coping only had higher depressive symptoms than those using a mix of coping strategies ( t = 2.60, p = .011). Healthcare providers can employ vigilant depression screening and en...

Healthy People 2020 set a goal to reduce by 10% the rate of suicide attempts that required treatment and designated the Youth Risk Behavior Survey (YRBS) to measure this objective. Objectives: This study used cross-sectional YRBS data (2009-2017) to (a) investigate whether gender moderates the linear time trend for the rate of depressive symptoms, suicidal ideation, and suicide attempts among high school students within the United States; (b) estimate these same measures stratified by gender; and (c) investigate whether the Healthy People 2020 goal for reduction in suicide attempts was met in 2017 for males and females. Methods: Secondary analysis of nationally representative high school students using YRBS data 2009-2017 were analyzed using R and the R survey package. Based on Strengthening the Reporting of Observational Studies in Epidemiology guidelines (STROBE), additive interactions using rate difference were compared to multiplicative interactions using odds ratios. Results: Additive interactions were identified between female gender and linear trends for depressive symptoms, suicidal ideation, and suicide attempts requiring treatment. Females, but not males, had positive linear trends for depressive symptoms, suicidal ideation, and suicide attempts requiring treatment. Suicide attempts requiring treatment among females was 36% higher in 2017 than in 2009 but decreased 13% in males during the same period. Discussion: The Healthy People 2020 goal to reduce suicide attempts requiring treatment by 10% has not been met among females. The divergent trends by gender highlight the importance of surveillance measures by gender. Future research is needed to identify better suicide prevention strategies that address underlying factors and are gender specific.

Rates of anxiety and depression were up to tenfold the prevalence of adolescents not diagnosed with autism or ADHD. Over half of autistic females (57%) and nearly half of autistic males (49%) are also diagnosed with ADHD. Autistic females with ADHD had the highest co-occurrence of anxiety at 72% followed by autistic males with ADHD at 69%. The prevalence of depression was highest among autistic adolescents with ADHD yet was consistent across genders (male/female) at 38-39%. Adolescents diagnosed with autism and/or ADHD are at heightened risk for anxiety and depression.

Univariate and multivariate analysis indicate that lesbian, gay, and bisexual adults are significantly more likely to flirt online and to use online dating websites and dating apps than heterosexual adults. Findings enhance understanding of LGB consumer decision-making processes, promote creation of LGB lifestyle-focused technologies and promotional messages for non-heterosexual niche audiences, and contribute to a better understanding of LGB online dating habits and usage.

Methods: Sixty patients who underwent surgical arthroscopy were prospectively, randomized into two separate groups. One cohort received a detailed e-mail of their procedure, discharge instructions, and labeled intraoperative arthroscopic images, while the second cohort received the standard preprinted instructions, while their arthroscopic images were discussed at the time of follow-up. The procedures were performed by a single surgeon. All patients were seen at 1-week follow-up and given a 14-question survey specific to their postoperative course, discharge instructions, and overall satisfaction using a 5-point Likert Scale. Demographic information was collected and data points comparing overall patient satisfaction, ease of understanding instructions, quality of information, and the number of times referenced were analyzed using nonparametric tests between the two cohorts. Results: Patients in the e-mail cohort were significantly more satisfied with their surgery than patients in the printed cohort (medians: 5 versus 4, Wilcoxon chisquare ¼ 9.98; P ¼.002). Patients in the e-mail cohort indicated that their instructions more greatly enhanced their overall understanding of their surgery (medians: 5 vs 3, Wilcoxon chi-square ¼ 10.84; P ¼ .001) and were more helpful to their recovery (medians: 5 vs 3, Wilcoxon chi-square ¼ 7.37; P ¼ .007). E-mail patients were significantly more likely to recommend similar instructions be sent to a friend undergoing surgery (medians: 5 versus 3, Wilcoxon chi-square ¼ 11.10; P < .001) and share their instructions with others 72% (18/25) versus 34.5% (10/29). There was no significant difference between the e-mail cohort and the print cohort for the number of times patients referred to their instructions (medians: 3 versus 3, Wilcoxon chi-square ¼ 2.41; P ¼.121). Conclusions: Patient-specific e-mailed discharge instructions improve patient satisfaction and overall understanding of the procedure compared with traditional printed discharge instructions after surgical arthroscopy. Level of Evidence: Level II, prospective randomized trial.

For this research, data were used from the National Postsecondary Student Aid Study: Undergraduate, which uses a complex survey design to collect data from a nationally representative sample of undergraduate postsecondary students in the US. Results show that a student’s field of study is significantly related to enrollment in distance education classes, enrollment in a distance education program, and satisfaction with distance education. Full-time employment, presence of dependents, and a mobility-limiting disability are also significantly associated with distance education preference. Enrollment trends show significant growth in distance education enrollment over 2000 to 2008 among students in all fields of study. Key Words: distance education enro...

The purpose of this research is to determine whether FGLI students in the US who enroll in distance education classes are likely to make greater academic progress (more likely to be enrolled for the entire academic year and more likely to be enrolled full time during the academic year) than FGLI students who enroll in face-to-face classes exclusively. For this research, we used data from the National Postsecondary Student Aid Survey (NPSAS) conducted in 2008. The NPSAS 2008 used a complex survey design to collect data from a nationally representative sample of about 113,500 postsecondary undergraduate students in the US. The results of this study show that FGLI students who e...

Since distance education courses provide students with more convenient and flexible class schedules, they should be preferred by students who have a greater number of competing demands, such as work and family, on their time. Not surprisingly, previous research has shown that such competing demands are also risk factors for undergraduate degree non-completion. Therefore a major purpose of this research is to examine whether students with risk factors for noncompletion of their undergraduate degree prefer distance education courses. Another purpose of this research is to examine whether students with a disability that limits their mobility, and thus experience greater barriers to access their face-to-face class rooms, prefer distance education classes. For this research, the data are from the National Postsecondary Student Aid Survey (N...
