The purpose of this study was to examine relationships among high school band festival ratings and director gender as well as school locale, school size, student socioeconomic status (SES), student race, repertoire difficulty, and ensemble name. Data included overall ratings of bands ( N = 257) that performed at District Concert Assessments held across the state of Virginia during 2019 as well as demographic information from the National Center for Education Statistics. Statistical analysis of a subset of these performances ( n = 151) revealed a statistically significant association between ratings and director gender, with male-directed ensembles more likely to receive a “I” rating than female-directed ensembles. However, hierarchical logistic regression revealed that repertoire difficulty and ensemble name were the best predictors of whether an ensemble would receive a “I” rating. Implications include the need to examine why female band directors may choose less difficult repertoire than male directors and to explore strategies for making the secondary band teaching profession more equitable and inclusive.

The purpose of this study was to examine inservice high school band directors’ perceptions and applications of democratic rehearsal procedures in concert band rehearsals. Respondents ( N = 216) were members of the National Association for Music Education who were currently teaching concert band at the high school level. Respondents indicated that “identify and describe opportunities for individual and ensemble performance improvement” and “student-led sectionals” were considered the most important democratic rehearsal procedures for their students to experience. These same procedures were also the most frequently used democratic rehearsal procedures. Analysis of open-ended responses revealed that respondents believed student ownership, student engagement, and student growth as musicians and leaders were advantages to implementing democratic rehearsal procedures. Potential disadvantages included issues related to student ability, rehearsal time limitations, unfamiliar classroom dynamics, and availability of classroom resources. Implications for music teachers are discussed.

Background: Recent studies suggest that statins are underprescribed in patients living with HIV (PLWH) at risk for atherosclerotic cardiovascular disease (ASCVD), but none have assessed if eligible patients receive the correct statin and intensity compared to uninfected controls. Objectives: The primary objective was to determine whether statin-eligible PLWH are less likely to receive appropriate statin therapy compared to patients without HIV. Methods: This retrospective study evaluated statin eligibility and prescribing among patients in both an HIV and internal medicine clinic at an urban, academic medical center from June-September 2018 using the American College of Cardiology/American Heart Association guideline on treating blood cholesterol to reduce ASCVD risk. Patients were assessed for eligibility and actual treatment with appropriate statin therapy. Characteristics of patients appropriately and not appropriately treated were compared with chi-square testing and predictors for receiving appropriate statin therapy were determined with logistic regression. Results: A total of 221/300 study subjects were statin-eligible. Fewer statin-eligible PLWH were receiving the correct statin intensity for their risk benefit group versus the uninfected control group (30.2% vs 67.0%, p < 0.001). In the multivariable logistic regression analysis, PLWH were significantly less likely to receive appropriate statin therapy, while those with polypharmacy were more likely to receive appropriate statin therapy. Conclusion: Our study reveals that PLWH may be at a disadvantage in receiving appropriate statin therapy for ASCVD risk reduction. This is important given the heightened risk for ASCVD in this population, and strategies that address this gap in care should be explored.

e16531 Background: Among the approaches to curative-intent therapy for MIBC, neoadjuvant cisplatin-based chemotherapy (NAC) is recognized as the gold standard. The combined modality approach of concurrent chemo-radiation is also considered a standard of care. Despite guidelines recommending multidisciplinary care, studies have shown a low adoption rate of multidisciplinary approaches for MIBC. This study aimed to describe the treatment patterns for MIBC pts using real world data. Methods: Following the appropriate IRB approvals, investigators followed a common protocol under the auspices of the Rapid Case Ascertainment at the Yale Cancer Center. Manual chart review was performed on MIBC pts diagnosed in Connecticut from 2004 –2015 and treated at investigator-affiliated hospitals. Information on medical history, comorbidity, and treatment types were recorded. This data set was linked to the Surveillance, Epidemiology, and End Results (SEER) database for demographic information. The descriptive and logistic regression were used to analyze treatment patterns and predicators in each treatment lines: surgery alone, chemotherapy alone, radiation alone and standard care (NAC followed by surgery; surgery followed by adjuvant chemotherapy and concurrent chemo-radiation). Results: The number of adult MIBC pts in the cohort was 1,198. Among them, 290 (24.2%) received surgery as the only treatment; 117 (9.8%) received chemotherapy only; 100 (8.3%) received concurrent chemo-radiation; 96 (8.0%) received NAC followed by surgery. Besides age ( OR: 0.546, 95% CI: 0.289-0.986), when comparing female to male patients on the likelihood of receiving NAC to the alternative treatment types (radiation or surgery), female pts were less likely to receive NAC than males (OR: 0.421, 95% CI: 0.184-0.930). Conclusions: Regardless of demographics, the overall adoption rate of standard care was low, consisting of 236 pts (19.7%) of the population. From the logistic regression results, age was consistently shown as a predictor for receiving NAC over the alternative treatment types, and sex was identified as another strong predictor. Older and female patients were less likely to receive NAC than younger males.[Table: see text]

Background and objectives: There are limited data on racial differences in clinical and economic outcomes of acute ischemic stroke (AIS) hospitalizations in the US. We sought to ascertain the effect of race on AIS outcomes in a population based retrospective cohort study. Methods: We used the 2012 National Inpatient Sample (NIS), which is the largest database of inpatient stays in the US, to identify cases of AIS using ICD9-CM codes 433.01, 433.11, 433.21, 433.31, 433.81, 433.91, 434.01, 434.11, 434.91 and 437.1 in patients >=18 years of age. Cases with missing data on race were excluded (5% of study sample). Primary outcome was in-hospital mortality. Secondary outcomes included proportion receiving endovascular mechanical thrombectomy (EMT) or thrombolysis, mean inflation adjusted charges and length of stay. Linear and logistic regression was used to test differences in continuous and categorical outcomes respectively. Survey techniques were used for all analyses. Results: There were 452, 330 hospitalizations for AIS in patients >=18 years in 2012. In univariate logistic regression using race as predictor, in-hospital mortality was significantly lower for Blacks (p<0.001), Hispanics (p=0.025) and Native Americans (p=0.047) compared to Whites. However, after adjusting for age, sex, Charlson comorbidity index, EMT and thrombolysis only blacks had a significantly lower mortality compared to whites (OR 0.74, 95% CI 0.66 - 0.82, p<0.001). Black patients were less likely to receive thrombolysis (OR 0.87, 95% CI 0.79 - 0.95; p=0.003) whereas Asian or Pacific Islanders were more likely to receive thrombolysis (OR 1.20, 95% CI 1.01 - 1.44; p=0.043) compared to whites. There was no difference in rates of EMT by race (p=0.18). Total charges and length of stay were significantly higher in racial minorities compared to whites (table). Conclusions: Blacks hospitalized for AIS have significantly lower in-hospital mortality compared to whites but are significantly less likely to receive thrombolysis compared to whites. Total charges and length of stay are significantly higher for racial minorities. Future studies should investigate mechanisms of this apparent protective effect of black race on in-hospital mortality in AIS.

Abstract Background To determine whether use of intrauterine device (IUD) is influenced by a history of induced abortion and the type of contraceptives used until costs are covered. Methods We analyzed data from 301 female residents in Mecklenburg-West Pomerania, an economically challenged community. The women, aged between 20 and 35 years, were entitled to receive unemployment benefits, and had access to free-of-charge oral contraceptives, ring or IUD. Cross-sectional data were analyzed using logistic regression. Results There were 112 (37.2%) women with a history of induced abortion, and 46 (15.3%) reported exclusively using less effective contraceptives (e.g. condoms). In a univariate logistic regression, use of an IUD was associated with a history of having had an induced abortion. Furthermore, uptake of an IUD was associated with women who had, until costs were covered, exclusively choice to use less effective contraceptives (OR = 3.281, 95% CI: 1.717; 6.273). Both associations remained significant in a multivariate model. Conclusions Free contraceptives provided to women receiving unemployment benefits may increase the use of IUDs, especially among those with a history of an induced abortion and those using less effective contraceptives.

Objective: Evidence regarding comedication among individuals with ADHD is lacking, especially in adults. This study investigated comedication and polypharmacy with ADHD medications in adults. Method: We identified adults dispensed with ADHD medications during 2013 in Sweden and matched them to controls. Logistic regression was used to calculate odds ratios (ORs) of receiving other medications. Results: Individuals receiving ADHD medications had higher risk of receiving any major classes of somatic medications (ORs ranged from 4.1, 95% confidence interval [CI] = [4.0, 4.3], to 7.4, 95% CI = [6.5, 8.5] across age groups). They were more likely to receive respiratory system, alimentary tract and metabolic system, and cardiovascular system medications. In addition, they had higher risk of receiving any other psychotropic medications. The proportion of polypharmacy with five or more medication classes increased from 10.1% to 60.4% from 18 to 64 years. Conclusion: Comedication was more common in adults receiving ADHD medications. Potential benefits and harms of comedication and polypharmacy require further research. (J. of Att. Dis. XXXX; XX[ X] XX-XX)

AbstractThe aim of the study was to assess, using population-based data, trends and regional variations in multiple births during the period of increasing use and changes in practice patterns for infertility treatments. National data for 24,554,977 births (live births and stillbirths) were used, including 569,423 twins during the period 1972 to 2003, and 14,599 triplets for 1984 to 2003. Statistical analyses included age-adjusted hierarchical logistic regression models for twin births and separate analyses for triple, same-sex, and different-sex twin births. Due to confidentiality considerations, the only variable available for adjustment was maternal age. Regionallevel variations were estimated using median odds ratios based on random-intercept hierarchical logistic regression models. Overall, twin births increased from 18.1 per 1000 births (95% confidence interval [CI] 17.9–18.2) in 1972 to 1975 to 29.9 per 1000 (95% CI 29.7–30.1) in 2000 to 2003. Twin births increased progressively across all regions, whereas triple births reached a peak in the early 1990s and decreased thereafter. Trends for both twin and triple births varied significantly across regions. Both trends and regional variations were greater for different-sex as compared with same-sex twin births. Regional variations in the proportion of multiple births increased in the case of twin births and decreased for triple births. Differences in multiple births at the regional level in France were comparable to country-level differences observed across several western and northern European countries. Regional differences in multiple births need to be monitored and used to inform policies aimed at regulating the use of infertility treatments.

We have previously shown that expression of oestrus significantly influences the time of ovulation and pregnancy rates to timed-AI (P/TAI) in beef cattle synchronized with progesterone devices and oestradiol (Bó et al. 2016 Theriogenology 86, 388–396). Furthermore, delaying TAI from 48 h to 54–58 h after device removal improved P/TAI of those animals not showing oestrus by 48 h. The objective of the present study was to determine whether the administration of GnRH to those animals not showing oestrus by 48 h after device removal had an impact on P/TAI. Non-lactating and suckled beef cows and heifers (Bonsmara, Brangus, and Braford; n = 868), with a corpus luteum (CL) or a follicle ≥8 mm in diameter detected by ultrasonography (Mindray DP 30 Vet, 7.5 MHz, China) and body condition score 2 to 4 (1 to 5 scale) were synchronized in 3 replicates. On Day 0, animals received a progesterone device (DIB 0.5 g, Zoetis, Argentina) and 2 mg of oestradiol benzoate (Von Franken, Argentina). On Day 8, DIB were removed and cows received 0.150 mg of D+cloprostenol (Río de Janeiro, Argentina) plus 0.5 mg oestradiol cypionate (Cipiosyn, Zoetis). In addition, all cows were tail-painted on the sacrococcygeal area (CeloTest, Biotay, Argentina) at DIB removal and were observed to determine the expression of oestrus, according to the percentage of paint loss (PL) 48 h later. The animals that showed oestrus (PL > 30%) were recorded and TAI at that time while those with PL ≤ 30% (not in oestrus) were randomly allocated to receive 100 μg of gonadorelin (GnRH; Gonasyn, Zoetis) or no treatment and TAI between 54 to 58 h after DIB removal. Pregnancy was diagnosed by ultrasonography at 45 days after TAI, and data were analysed by logistic regression. There were no significant differences among replicates, inseminators, semen source or animal class (dry cows, suckled cows or heifers; P > 0.11). However, animals showing oestrus by 48 h after DIB removal had higher P/TAI (371/666; 55.7; P < 0.04) than those that did not show oestrus (96/202; 47.5%). Within animals not showing oestrus at 48 h, those that were in oestrus by the TAI at 54 to 58 h had higher P/TAI (71/124, 57.3%; P < 0.01) than those that did not show oestrus within that period (27/78; 34.6%). In addition, P/TAI was higher (P < 0.01) in animals that received GnRH (66/113; 58.4%) than in those that did not receive GnRH (30/89; 33.7%). In conclusion, the expression of oestrus significantly affected P/TAI in beef cattle synchronized with progesterone devices and oestradiol. Furthermore, treatment of animals not showing oestrus by 48 h after DIB removal with GnRH resulted in improved P/TAI performed 6 to 10 h later.
