RESUMEN

Background: Older adults, an increasingly diverse segment of the United States population, are a priority population for prescription painkiller misuse. This study documents trends and correlates of prescription painkiller misuse among Hispanic and non-Hispanic adults ages 50 and older. Methods: A secondary analysis of adults 50 years and older across 5 cohorts using the 2015-2019 National Survey on Drug Use and Health (unweighted n = 16,181, 8.5% Hispanic, and 54% female). Logistic regression modeling with complex survey design was used to examine trends in prescription painkiller misuse. Results: Over time, the prevalence of past year painkiller misuse significantly decreased for Hispanic respondents (56.1% relative decrease, p = 0.02); elevated proportions were observed across strata of demographic characteristics. Conclusions: Variability in the prevalence of painkiller misuse may be explained by demographic characteristics. Further, these results emphasize the importance of addressing comorbid recreational marijuana use when designing interventions to address painkiller misuse for older adults.

RESUMEN

BACKGROUND: Hypertension is typically recognized in middle-aged and older adults but often overlooked in younger populations. OBJECTIVE: We evaluated a mobile intervention for reducing blood pressure (BP) in college-age students for 28 days. METHODS: Students with elevated BP or undiagnosed hypertension were assigned to an intervention or control group. All subjects completed baseline questionnaires and attended an educational session. For 28 days, intervention subjects sent their BP and motivation levels to the research team and completed assigned BP-reducing tasks. After 28 days, all subjects completed an exit interview. RESULTS: We found a statistically significant decrease in BP in the intervention group only ( P = .001) but no statistical difference in sodium intake for either group. Mean hypertension knowledge increased in both groups but was only significant for the control group ( P = .001). CONCLUSIONS: The results provide preliminary data on BP reduction with greater impact on the intervention group.

RESUMEN

The influx of military Veterans with posttraumatic stress disorder (PTSD) returning to college following active military service presents an unmanageable trend for many secondary educational institutions in the United States. The current study aimed to determine relationships among rumination, resilience, mindfulness, and perceived PTSD symptoms in college student Veterans. To this end, 133 college student military Veterans registered in a U.S. university responded to an online survey. Results revealed that rumination has a direct effect on perceived PTSD symptoms and mediates the relationship between mindfulness and perceived PTSD symptoms, and that resilience moderates the relationship between mindfulness and perceived PTSD symptoms through rumination as the mediator. These findings imply that designing and developing mindfulness-based interventions for college student Veterans with PTSD requires concerted efforts targeted at improving ruminative thinking and enhancing resilience.

RESUMEN

The purpose of the study was to investigate the moderating effect of resilience on the relationship between mindfulness, experiential avoidance, and posttraumatic stress disorder (PTSD) symptom severity. A cross-sectional study design was used on a sample of 133 college student military veterans. We found a direct effect of mindfulness on PTSD and a significant mediating effect of experiential avoidance on the relationship between mindfulness and PTSD. Resilience also had a significant moderating effect on the relationship between mindfulness and PTSD. This study provides preliminary evidence on the usefulness of integrating resilience development in mindfulness-based interventions for trauma-related disorders.

RESUMEN

In the era of highly active antiretroviral therapy (HAART), obesity is increasingly being reported among people living with HIV (PLHIV). In this study, we reviewed published literature on body mass index (BMI) changes among treatment-naïve adult PLHIV who started HAART and remained on treatment for at least six months. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline, four databases were searched, and results of included studies were synthesized to describe the BMI trend among PLHIV on treatment. The search generated 4948 studies, of which 30 were included in the qualitative synthesis and 18 were eligible for the meta-analysis. All the studies showed an increase in group BMI. HAART was associated with increase in BMI (pooled effect size [ES] = 1.58 kg/m2; 95% CI: 1.36, 1.81). The heterogeneity among the 18 studies was high (I2 = 85%; p < .01). Subgroup analyses showed pooled ES of 1.54 kg/m2 (95% CI: 1.21, 1.87) and 1.63 kg/m2 (95% CI: 1.34, 1.91) for studies with follow-up ≤1 year and >1 year, respectively. We conclude that the greatest gain in BMI is in the initial 6-12 months on treatment, with minor gains in the second and subsequent years of treatment.

RESUMEN

INTRODUCTION: We investigated the preliminary effects of dietary changes on the anthropometric measurements of child and adolescent Hadza foragers. METHODS: We conducted a cross-sectional study comparing height and weight of participants (aged 0-17 years) at two time points, 2005 (n = 195) and 2017 (n = 52), from two locations: semi-nomadic "bush camps" and sedentary "village camps". World Health Organization (WHO) calculators were used to generate standardized z-scores for weight-for-height (WHZ), weight-for-age (WAZ), height-for-age (HAZ), and BMI-for-age (BMIFAZ). Cross tabulations were constructed for each measurement variable as a function of z-score categories and the variables year, location, and sex. RESULTS: Residency in a village, and associated mixed-subsistence diet, was associated with favorable growth, including greater WAZ (P < .001), HAZ (P < .001), and BMIFAZ (P = .004), but not WHZ (P = .717). Regardless of residency location, participants showed an improved WAZ (P = .021) and HAZ (P < .001) in the 2017 study year. We found no sex differences. DISCUSSION AND CONCLUSION: These preliminary findings suggest that a mixed-subsistence diet may confer advantages over an exclusive wild food diet, a trend also reported among other transitioning foragers.

RESUMEN

BACKGROUND AND AIMS: Fecal microbiota transplantation (FMT) is used in recurrent Clostridioides difficile infections. However, protocols are facility dependent, and one variable is whether pre-procedural proton pump inhibitors (PPIs) are given. In theory, PPIs reduce acidity and protect the transplanted microbiome for the most potent dose. We conducted a systematic review to study the effect of PPIs on FMT delivered by upper gastrointestinal (GI) routes. METHODS: We searched Pubmed/Medline, Cochrane Library, Embase, Scopus, and Web of Science through December 16, 2018 using variations of keywords "fecal microbiota transplant" and "Clostridium difficile infection." Two authors independently reviewed 4210 results and found 11 qualifying studies with data on upper GI FMT, use of PPIs, and the rate of treatment failure at follow-up. RESULTS: Of 233 included patients, treatment failure occurred in 20.6% of those with use of PPIs versus 22.6% in the group without (relative risk 0.91; confidence interval 0.56-1.50). Limitations include the lack of studies directly comparing outcomes based on use of PPIs and inability to control for possible confounders such as chronic PPI use, amount of stool transplanted, and pre-FMT antibiotics. CONCLUSIONS: We did not find evidence supporting a clinically significant benefit from routine use of PPIs in FMT protocol. It is possible that the theoretical benefit from improved survival of transplanted microbiota is offset by negative effects on the microbiome. We suggest that routine use of PPIs in upper GI FMT be reconsidered. Further investigation is needed to optimize protocols for safety and efficacy.

RESUMEN

Resilience refers to a set of personal qualities and abilities that allow an individual to confront challenges, risks, or traumatic experiences in an integrated manner and to thrive in the face of significant adversities. This cross-sectional study explores resilience, posttraumatic stress disorder (PTSD), and family norms with disclosure of mental health problems (FNAD) in a sample of 182 Filipino American women (FAW). Participants completed survey measures of resilience, PTSD, and FNAD and open-ended questions about beliefs and reasons for (not) disclosing mental health problems outside the family. Previous research found that the rates of psychological trauma and depression among FAW are higher than those in other Asian ethnic groups, which makes it necessary to investigate the protective characteristic of resilience among FAW. According to our results, foreign-born FAW had a significantly lower PTSD and greater resilience as compared to their US-born counterparts. A significant negative relationship between PTSD and resilience was observed only among foreign-born FAW. We also found a conditional moderating effect of FNAD on the negative relationship between resilience and PTSD. The results of our qualitative analysis of the participants' responses to the open-ended questions of the survey showed that FAW's family norms of nondisclosure are related to the cultural value of "saving face," a salient cultural construct among Asian family members. Results suggest that protective properties of resilience against PTSD are influenced by cultural factors, such as FNAD. Taken together, our findings underscore the importance of considering the impact of collectivistic cultural values (e.g., FNAD) in future research on resilience among Asian Americans.

RESUMEN

AIMS: To explore the types of traumatic exposure, prevalence of posttraumatic stress disorder (PTSD), and level of resilience in a community sample of Filipino American women (FAW), as well as to investigate the relationships between their PTSD symptoms, history of traumatic exposure, and resilience. METHOD: A cross-sectional study with a total of 188 adult FAW. RESULTS: We observed high levels of resilience and low levels of PTSD symptom severity. The most common form of traumatic exposure was non-interpersonal trauma occurring after the age of 18 years old. We also found a significant correlation between history of traumatic exposure and PTSD and between resilience and PTSD. Resilience was found to have a significant moderating effect on the relationship between traumatic exposure and PTSD. CONCLUSIONS: The results provide preliminary evidence on the buffering and protective properties of FAW's resilience to PTSD despite traumatic exposure.

RESUMEN

Teramoto, M, Cross, CL, Rieger, RH, Maak, TG, and Willick, SE. Predictive validity of national basketball association draft combine on future performance. J Strength Cond Res 32(2): 396-408, 2018-The National Basketball Association (NBA) Draft Combine is an annual event where prospective players are evaluated in terms of their athletic abilities and basketball skills. Data collected at the Combine should help NBA teams select right the players for the upcoming NBA draft; however, its value for predicting future performance of players has not been examined. This study investigated predictive validity of the NBA Draft Combine on future performance of basketball players. We performed a principal component analysis (PCA) on the 2010-2015 Combine data to reduce correlated variables (N = 234), a correlation analysis on the Combine data and future on-court performance to examine relationships (maximum pairwise N = 217), and a robust principal component regression (PCR) analysis to predict first-year and 3-year on-court performance from the Combine measures (N = 148 and 127, respectively). Three components were identified within the Combine data through PCA (= Combine subscales): length-size, power-quickness, and upper-body strength. As per the correlation analysis, the individual Combine items for anthropometrics, including height without shoes, standing reach, weight, wingspan, and hand length, as well as the Combine subscale of length-size, had positive, medium-to-large-sized correlations (r = 0.313-0.545) with defensive performance quantified by Defensive Box Plus/Minus. The robust PCR analysis showed that the Combine subscale of length-size was a predictor most significantly associated with future on-court performance (p ≤ 0.05), including Win Shares, Box Plus/Minus, and Value Over Replacement Player, followed by upper-body strength. In conclusion, the NBA Draft Combine has value for predicting future performance of players.

RESUMEN

The National Football League (NFL) Scouting Combine is held each year before the NFL Draft to measure athletic abilities and football skills of college football players. Although the NFL Scouting Combine can provide the NFL teams with an opportunity to evaluate college players for the upcoming NFL Draft, its value for predicting future success of players has been questioned. This study examined whether the NFL Combine measures can predict future performance of running backs (RBs) and wide receivers (WRs) in the NFL. We analyzed the 2000-09 Combine data of RBs (N = 276) and WRs (N = 447) and their on-field performance for the first 3 years after the draft and over their entire careers in the NFL, using correlation and regression analyses, along with a principal component analysis (PCA). The results of the analyses showed that, after accounting for the number of games played, draft position, height (HT), and weight (WT), the time on 10-yard dash was the most important predictor of rushing yards per attempt of the first 3 years (p = 0.002) and of the careers (p < 0.001) in RBs. For WRs, vertical jump was found to be significantly associated with receiving yards per reception of the first 3 years (p = 0.001) and of the careers (p = 0.004) in the NFL, after adjusting for the covariates above. Furthermore, HT was most important in predicting future performance of WRs. The analyses also revealed that the 8 athletic drills in the Combine seemed to have construct validity. It seems that the NFL Scouting Combine has some value for predicting future performance of RBs and WRs in the NFL.

RESUMEN

The aims of this study were to (1) explore this sample's pre- and post-intervention dietary intake, specifically the macro- and micronutrients, and their eating habits related to location of consumption and use of electronic devices, and (2) compare this sample's nutritional measures to the current Dietary Guidelines 2020 to 2025. Twenty-eight participants were included in the secondary data analysis. Participants reported a total of 822 items consumed during this study. Most items were consumed at home (n = 629, 76.5%). We found significant differences in the intake of energy, protein, total fat, carbohydrates, total vegetables, total grains, and total meat in different locations. For most of these measures, consumption at home and/or restaurants resulted in a greater magnitude of consumption than at other locations (e.g., car, daycare). Participants reported consuming most of their energy and nutrients while either using electronic devices alone (n = 365, 44.4%) or using no devices (n = 346, 42.1%). Significant differences were found among three measures including energy, total fat, and total fiber. The majority of the macronutrients (total fiber, fruits, vegetables, meat, and dairy) consumed by our sample were under the threshold recommended in the 2020 to 2025 Dietary Guidelines.

RESUMEN

OBJECTIVES: Clinical criteria for Traumatic Encephalopathy Syndrome (ccTES) were developed for research purposes to reflect the clinical symptoms of Chronic Traumatic Encephalopathy (CTE). The aims of this study were to 1) determine whether there was an association between the research diagnosis of TES and impaired postural balance among retired professional fighters, and 2) determine repetitive head impacts (RHI) exposure thresholds among both TES positive and TES negative groups in retired professional fighters when evaluating for balance impairment. METHODS: This was a pilot study evaluating postural balance among participants of the Professional Athletes Brain Health Study (PABHS). Among the cohort, 57 retired professional fighters met the criteria for inclusion in this study. A generalized linear model with generalized estimating equations was used to compare various balance measures longitudinally between fighters with and without TES. RESULTS: A significant association was observed between a TES diagnosis and worsening performance on double-leg balance assessments when stratifying by RHI exposure thresholds. Additionally, elevated exposure to RHI was significantly associated with increased odds of developing TES; The odds for TES diagnosis were 563% (95% CI = 113, 1963; p-value = 0.0011) greater among athletes with 32 or more professional fights compared to athletes with less than 32 fights when stratifying by balance measures. Likewise, the odds for TES diagnosis were 43% (95% CI = 10, 102; p-value = 0.0439) greater with worsening double leg stance balance in athletes exposed to 32 or more fights. CONCLUSION: This pilot study provides preliminary evidence of a relationship between declining postural balance and a TES diagnosis among retired professional fighters with elevated RHI exposure. Further research exploring more complex assessments such as the Functional Gait Assessment may be of benefit to improve clinical understanding of the relationship between TES, RHI, and balance.

RESUMEN

BACKGROUND AND OBJECTIVES: Limbic-predominant age-related TDP-43 encephalopathy (LATE) affects similar neuroanatomical networks as Alzheimer disease (AD) and is often comorbid with AD, though frequently missed in clinical diagnosis. The primary aim of this study was to elucidate the clinical and cognitive differences at baseline between patients with autopsy-confirmed LATE and patients with AD and comorbid LATE + AD. METHODS: Clinical and neuropathologic datasets were requested from the National Alzheimer Coordination Center. Baseline data from individuals older than 75 years during death without neuropathologic indication of frontotemporal lobar degeneration were included in analyses. Pathologically defined groups reflecting LATE, AD, and comorbid LATE + AD were identified. Group differences in clinical characteristics and cognition were explored through analysis of variance and the χ2 using measures from the Uniform Data Set measures. RESULTS: Pathology groups included 31 individuals with LATE (mean age: 80.6 ± 5.4 years), 393 with AD (mean age: 77.8 ± 6.4 years), and 262 with LATE + AD (mean age: 77.8 ± 6.6 years) without significant differences in sex, education, or race. Compared with participants with AD and LATE + AD pathology, participants with LATE pathology lived significantly longer (mean visits: LATE = 7.3 ± 3.7; AD = 5.8 ± 3.0; and LATE + AD = 5.8 ± 3.0; F(2,683) = 3.7, p < 0.05), reported later onset of cognitive decline (mean onset: LATE = 78.8 ± 5.7; AD = 72.5 ± 7.0; and LATE + AD = 72.9 ± 7.0; F(2,516) = 6.2, p < 0.01), and were more likely to be diagnosed as cognitively normal at baseline (LATE = 41.9%; AD = 25.4%; and LATE + AD = 12%; χ2 = 38.7, p < 0.001). Individuals with LATE (45.2%) also reported fewer memory complaints than those with AD (74.4%) or LATE + AD (66.4%; χ2 = 13.3, p = 0.001) and were less likely to be classified as impaired on the Mini-Mental State Examination (LATE = 6.5%; AD = 24.2%; and LATE + AD = 40.1%; χ2 = 29.20, p < 0.001). Across all neuropsychological measures, participants with LATE + AD pathology performed significantly worse than the AD and LATE groups. DISCUSSION: Those with LATE pathology were older when cognitive symptoms began and lived longer than participants with AD or LATE + AD pathology. Participants with LATE pathology were also more likely to be classified as "cognitively normal" based on objective screening and self-report measures, and they had higher scores on neuropsychological testing. Consistent with prior literature, comorbid pathologies led to more significant cognitive and functional impairment. Early disease characteristics based on clinical presentation alone were insufficient for differentiating LATE from AD, reiterating the need for a validated biomarker.

RESUMEN

BACKGROUND AND OBJECTIVES: Due to current limitations in diagnosing chronic traumatic encephalopathy (CTE) clinically, traumatic encephalopathy syndrome (TES) has been proposed as the clinical presentation of suspected CTE. This study aimed to determine whether there was an association between a clinical diagnosis of TES and subsequent temporal decline in cognitive or MRI volumetric measures. METHODS: This was a secondary analysis of the Professional Athletes Brain Health Study (PABHS), inclusive of active and retired professional fighters older than 34 years. All athletes were adjudicated as TES positive (TES+) or TES negative (TES-) based on the 2021 clinical criteria. General linear mixed models were used to compare MRI regional brain volumes and cognitive performance between groups. RESULTS: A total of 130 fighters met inclusion criteria for consensus conference. Of them, 52 fighters (40%) were adjudicated as TES+. Athletes with a TES+ diagnosis were older and had significantly lower education. Statistically significant interactions and between-group total mean differences were found in all MRI volumetric measurements among the TES+ group compared with those among the TES- group. The rate of volumetric change indicated a significantly greater increase for lateral (estimate = 5,196.65; 95% CI = 2642.65, 7750.66) and inferior lateral ventricles (estimate = 354.28; 95% CI = 159.90, 548.66) and a decrease for the hippocampus (estimate = -385.04, 95% CI = -580.47, -189.62), subcortical gray matter (estimate = -4,641.08; 95% CI = -6783.98, -2498.18), total gray matter (estimate = -26492.00; 95% CI = -50402.00, -2582.32), and posterior corpus callosum (estimate = -147.98; 95% CI = -222.33, -73.62). Likewise, the rate of cognitive decline was significantly greater for reaction time (estimate = 56.31; 95% CI = 26.17, 86.45) and other standardized cognitive scores in the TES+ group. DISCUSSION: The 2021 TES criteria clearly distinguishes group differences in the longitudinal presentation of volumetric loss in select brain regions and cognitive decline among professional fighters 35 years and older. This study suggests that a TES diagnosis may be useful in professional sports beyond football, such as boxing and mixed martial arts. These findings further suggest that the application of TES criteria may be valuable clinically in predicting cognitive decline.

RESUMEN

BACKGROUND: Insecticide resistance among malaria-vector species is a pervasive problem that might jeopardise global disease-control efforts. Novel vector-control tools with different modes of action, including long-lasting insecticidal nets (LLINs) incorporating new active ingredients, are urgently needed to delay the evolution and spread of insecticide resistance. We aimed to measure phenotypic and genotypic insecticide-resistance profiles among wild Anopheles collected over 3 years to assess the longitudinal effects of dual-active-ingredient LLINs on insecticide resistance. METHODS: For this analysis, data nested in a 3-year, four parallel-arm, superiority cluster-randomised controlled trial (cRCT) in Tanzania, collected from 84 clusters (39 307 households) formed of 72 villages in the Misungwi district, were used to measure insecticide-resistance profiles among female Anopheles mosquitoes via insecticide-resistance bioassays and quantitative RT-PCR of metabolic-resistance genes. Wild, blood-fed, indoor-resting mosquitoes were collected annually during the rainy seasons from house walls in clusters from all four trial groups. Mosquitoes were morphologically identified as An gambiae sensu lato (SL) or An funestus SL before separate bioassay testing. The primary outcomes were lethal-dose values for α-cypermethrin, permethrin, and piperonyl butoxide pre-exposure plus permethrin-resistance intensity bioassays, mortality 72 h after insecticidal exposure for chlorfenapyr bioassays, fertility reduction 72 h after insecticidal exposure for pyriproxyfen bioassays, and fold change in metabolic-enzyme expression relative to an insecticide-susceptible laboratory strain. All primary outcomes were measured in An funestus SL 1 year, 2 years, and 3 years after LLIN distribution. Primary outcomes were also assessed in An gambiae SL if enough mosquitoes were collected. The cRCT is registered with ClinicalTrials.gov (NCT03554616). FINDINGS: Between May 24, 2019, and Oct 25, 2021, 47 224 female Anopheles were collected for resistance monitoring. In the pyrethroid (PY)-LLIN group, there were significant increases in α-cypermethrin-resistance intensity (year 1 LD50=9·52 vs year 2 76·20, p<0·0001) and permethrin-resistance intensity (year 1 13·27 vs year 2 35·83, p=0·0019) in An funestus SL. In the pyriproxyfen PY-LLIN group, there was similar increase in α-cypermethrin-resistance intensity (year 1 0·71 vs year 2 81·56, p<0·0001) and permethrin-resistance intensity (year 1 5·68 vs year 2 50·14, p<0·0001). In the piperonyl butoxide PY-LLIN group, α-cypermethrin-resistance intensity (year 1 33·26 vs year 3 70·22, p=0·0071) and permethrin-resistance intensity (year 1 47·09 vs year 3 2635·29, p<0·0001) also increased over time. In the chlorfenapyr PY-LLIN group, there were no effects on α-cypermethrin-resistance intensity (year 1 0·42 vs year 3 0·99, p=0·54) or permethrin-resistance intensity (data were not estimable due to nearly 100% mortality). There were also minimal reductions in chlorfenapyr susceptibility. However, in the chlorfenapyr PY-LLIN group, a significant decline in piperonyl-butoxide synergy was seen by year 3 (year 1 0·02 vs year 3 0·26, p=0·020). Highly over-expressed detoxification enzymes showed dynamic patterns of selection throughout the trial. INTERPRETATION: Our phenotypic data supports trial epidemiological findings; chlorfenapyr PY-LLINs provided superior protection from malaria across multiple transmission seasons, with few effects on insecticide-resistance selection. Rapid pyrethroid-resistance intensification in the piperonyl butoxide PY-LLIN group and pre-existing tolerance of pyriproxyfen in vector populations might explain the poorer performance of these two interventions regarding malaria outcomes. Further work is required to elucidate the potential mechanisms driving cross-resistance between pyrethroids and novel active ingredients to better inform the design of pre-emptive resistance-management strategies.

RESUMEN

Dengue Fever (DF) is an important arthropod-borne viral infection that has repeatedly occurred as outbreaks in eastern and northeastern Ethiopia since 2013. A cross-sectional epidemiological outbreak investigation was carried out from September to November 2019 on febrile patients (confirmed malaria negative) who presented with suspected and confirmed DF at both public and private health facilities in Gewane District, Afar Region, northeastern Ethiopia. Entomological investigation of containers found in randomly selected houses belonging to DF-positive patients was undertaken to survey for the presence of Aedes larvae/pupae. A total of 1185 DF cases were recorded from six health facilities during the 3-month study period. The mean age of DF cases was 27.2 years, and 42.7% of cases were female. The most affected age group was 15−49 years old (78.98%). The total case proportions differed significantly across age groups when compared to the population distribution; there were approximately 15% and 5% higher case proportions among those aged 15−49 years and 49+ years, respectively. A total of 162 artificial containers were inspected from 62 houses, with 49.4% found positive for Aedes aegypti larva/pupae. Aedes mosquitoes were most commonly observed breeding in plastic tanks, tires, and plastic or metal buckets/bowls. World Health Organization entomological indices classified the study site as high risk for dengue virus outbreaks (House Index = 45.2%, Container Index = 49.4%, and Breteau Index = 129). Time series climate data, specifically rainfall, were found to be significantly predictive of AR (p = 0.035). Study findings highlight the importance of vector control to prevent future DF outbreaks in the region. The scarcity of drinking water and microclimatic conditions may have also contributed to the occurrence of this outbreak.

RESUMEN

OBJECTIVE: To provide an updated analysis of opioid-related injuries in Nevada and provide a first-time analysis of the intravenous drug user (IDU) population within Clark County. DESIGN: Cross-sectional study. SETTING: Center for Health Information Analysis (CHIA) database and IDU data from Trac-B Exchange (Trac-B). PARTICIPANTS: Patients hospitalized for opioid-related causes (n = 9,064) and participants from Trac-B. MAIN OUTCOME MEASURE(S): Variables assessed included age, gender, and race/ethnicity. Zip codes were retrieved to find differences in geographical usage patterns of hospital or sterile injection equipment (SEP) sites. Contingency tables were utilized to determine the frequency of comorbidities. Additionally, GIS was used to investigate potential spatial patterns of interest. RESULTS: Totally 5,268 out of the 9,064 opioid-related cases reported in Nevada were Clark County residents. The highest frequency for comorbidities associated with opioid-related hospitalizations (ORHs) included: infections, chronic bodily pain, and malnutrition. There was a higher proportion of 18-35-year-olds who used SEPs as compared to hospitals and a higher proportion of individuals aged 36 years or older who used hospitals as compared to using SEPs. Of the nearly 100 zip codes in Clark County, six showed a disproportionally high frequency of ORHs, and three comprised the majority of injection drug use. CONCLUSIONS: There is an opioid epidemic in Nevada that has contributed to addiction, heroin usage, injection drug use, and transmission of bloodborne diseases. Understanding the ORHs and intravenous drug use trends can help guide the development of program interventions.

RESUMEN

OBJECTIVE: The presence of neurodevelopmental disorders (ND) such as attention-deficit/hyperactivity disorder (ADHD) and learning disorders (LD) have demonstrated effects on Immediate Post-concussion Assessment and Cognitive Testing (ImPACT) performance. No current research has directly examined whether autism spectrum disorder (ASD) has similar effects. The current study compared ImPACT cognitive and symptom profiles in athletes with self-reported ASD to other NDs and healthy controls using case-control matching. METHOD: The current study compared ImPACT baselines of high school athletes with ASD to athletes with other NDs (ADHD, LD, and co-occurring ADHD/LD) and healthy controls on cognitive composites and symptom reporting. Participants included 435 athletes (87 controls, 87 with ASD, 87 with ADHD, 87 with LD, and 87 with ADHD/LD) selected from a larger naturalistic sample. Athletes were matched to the ASD group based on age, sex, and sport using randomized case-matched selection from the larger database. RESULTS: Results revealed that athletes with ASD performed more poorly than healthy controls on the Visual Motor Speed composite. No differences were found for Post-concussion Symptom Scale (PCSS) domain scores. Differences in cognitive and symptom profiles among the athletes with other NDs were also found. CONCLUSIONS: Results elucidate patterns of baseline performance for athletes with ASD, demonstrating that there may not be significant differences between ASD and healthy controls on four of the five ImPACT composites, and no symptom reporting differences. Cognitive and symptom differences found for other NDs should be considered when interpreting baseline performance and for making return-to-play decisions in the absence of baseline assessment.

RESUMEN

BACKGROUND: Studies show that patients make lifestyle changes soon after certain solid tumor diagnoses, suggesting that this may be a teachable moment to motivate and promote healthy behaviors. There is a paucity of data regarding changes made after a diagnosis of a hematologic malignancy. METHODS: A cross-sectional study of 116 patients at a community oncology center who completed anonymous questionnaires was performed. Questions addressed lifestyle choices made with respect to smoking, alcohol consumption, recreational drug use, diet, and exercise habits before and after diagnosis of a hematologic malignancy. Support systems utilized, including psychiatry services, were also assessed. RESULTS: Patients exhibited significant reduction in smoking behavior (Χ2  = 31.0, p < 0.001). 82.4% (n = 14) of one pack per day smokers quit between the time periods, with nearly all smokers showing a reduction after diagnosis. Alcohol use overall did not change significantly, however, 10.3% (n = 12) of patients reported quitting drinking completely between time periods. Changes in dietary intake and exercise were not statistically significant overall. Utilization of external support systems correlated with improved diet as well as decrease in total smoking years. CONCLUSIONS: This study demonstrates that patients exhibited significant lifestyle changes after being diagnosed with a hematologic malignancy. Clinicians should take advantage of this 'teachable moment' to educate patients about positive health behavior changes. Advances in cancer therapeutics have led to an increase in cancer survivors, this education is crucial in reducing the risk of developing chronic comorbidities as well as secondary malignancies.
