Magnetic Resonance Imaging Follow-up of Targeted Biopsy-negative Prostate Lesions.

BACKGROUND: The optimal radiological follow-up of prostate lesions negative on magnetic resonance imaging (MRI)-targeted biopsy (MRI-TB) is yet to be optimised. OBJECTIVE: To present medium-term radiological and clinical follow-up of biopsy-negative lesions. DESIGN, SETTING, AND PARTICIPANTS: The records for men who underwent multiparametric MRI at the UCLH one-stop clinic for suspected prostate cancer between September 2017 and March 2020 were reviewed (n = 1199). Patients with Likert 4 or 5 lesions were considered (n = 495), and those with a subsequent negative MRI-TB comprised the final study population (n = 91). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Baseline and follow-up MRI and biopsy data (including prostate-specific antigen [PSA], prostate volume, radiological scores, and presence of any noncancerous pathology) were extracted from reports. The last follow-up date was the date of the last test or review in clinic. RESULTS AND LIMITATIONS: Median follow-up was 1.8 yr (656 d, interquartile range [IQR] 359-1008). At baseline, the median age was 65.4 yr (IQR 60.7-70.0), median PSA was 7.1 ng/ml (IQR 4.7-10.0), median prostate volume was 54 ml (IQR 39.5-75.0), and median PSA density (PSAD) was 0.13 ng/ml2 (IQR 0.09-0.18). Eighty-six men (95%) had Likert 4 lesions, while the remaining five (5%) had Likert 5 lesions. Only 21 men (23%) had a single lesion; most had at least two. Atrophy was the most prevalent pathology on MRI-TB, present in 64 men (74%), and followed by acute inflammation in 42 (46%), prostatic intraepithelial neoplasia in 33 (36%), chronic inflammation in 18 (20%), atypia in 13 (14%), and granulomatous inflammation in three (3%). Fifty-eight men had a second MRI study (median 376 d, IQR 361-412). At the second MRI, median PSAD decreased to 0.11 ng/ml2 (IQR 0.08-0.18). A Likert 4 or 5 score persisted only in five men (9%); 40 men (69%) were scored Likert 3, while the remaining 13 (22%) were scored Likert 2 (no lesion). Of 45 men with a Likert ≥3 score, most only had one lesion at the second MRI (28 men; 62%). Of six men with repeat MRI-TB during the study period, two were subsequently diagnosed with prostate cancer and both had persistent Likert 4 scores (at baseline and at least one follow-up MRI). CONCLUSIONS: Most biopsy-negative MRI lesions in the prostate resolve over time, but any persistent lesions should be closely monitored. PATIENT SUMMARY: Lesions in the prostate detected via magnetic resonance imaging (MRI) scans that are negative for cancer on biopsy usually resolve. Repeat MRI can indicate persistent lesions that might need a second biopsy.

Multiparametric ultrasound versus multiparametric MRI to diagnose prostate cancer (CADMUS): a prospective, multicentre, paired-cohort, confirmatory study.

BACKGROUND: Multiparametric MRI of the prostate followed by targeted biopsy is recommended for patients at risk of prostate cancer. However, multiparametric ultrasound is more readily available than multiparametric MRI. Data from paired-cohort validation studies and randomised, controlled trials support the use of multiparametric MRI, whereas the evidence for individual ultrasound methods and multiparametric ultrasound is only derived from case series. We aimed to establish the overall agreement between multiparametric ultrasound and multiparametric MRI to diagnose clinically significant prostate cancer. METHODS: We conducted a prospective, multicentre, paired-cohort, confirmatory study in seven hospitals in the UK. Patients at risk of prostate cancer, aged 18 years or older, with an elevated prostate-specific antigen concentration or abnormal findings on digital rectal examination underwent both multiparametric ultrasound and multiparametric MRI. Multiparametric ultrasound consisted of B-mode, colour Doppler, real-time elastography, and contrast-enhanced ultrasound. Multiparametric MRI included high-resolution T2-weighted images, diffusion-weighted imaging (dedicated high B 1400 s/mm2 or 2000 s/mm2 and apparent diffusion coefficient map), and dynamic contrast-enhanced axial T1-weighted images. Patients with positive findings on multiparametric ultrasound or multiparametric MRI underwent targeted biopsies but were masked to their test results. If both tests yielded positive findings, the order of targeting at biopsy was randomly assigned (1:1) using stratified (according to centre only) block randomisation with randomly varying block sizes. The co-primary endpoints were the proportion of positive lesions on, and agreement between, multiparametric MRI and multiparametric ultrasound in identifying suspicious lesions (Likert score of ≥3), and detection of clinically significant cancer (defined as a Gleason score of ≥4 + 3 in any area or a maximum cancer core length of ≥6 mm of any grade [PROMIS definition 1]) in those patients who underwent a biopsy. Adverse events were defined according to Good Clinical Practice and trial regulatory guidelines. The trial is registered on ISRCTN, 38541912, and ClinicalTrials.gov, NCT02712684, with recruitment and follow-up completed. FINDINGS: Between March 15, 2016, and Nov 7, 2019, 370 eligible patients were enrolled; 306 patients completed both multiparametric ultrasound and multiparametric MRI and 257 underwent a prostate biopsy. Multiparametric ultrasound was positive in 272 (89% [95% CI 85-92]) of 306 patients and multiparametric MRI was positive in 238 patients (78% [73-82]; difference 11·1% [95% CI 5·1-17·1]). Positive test agreement was 73·2% (95% CI 67·9-78·1; κ=0·06 [95% CI -0·56 to 0·17]). Any cancer was detected in 133 (52% [95% CI 45·5-58]) of 257 patients, with 83 (32% [26-38]) of 257 being clinically significant by PROMIS definition 1. Each test alone would result in multiparametric ultrasound detecting PROMIS definition 1 cancer in 66 (26% [95% CI 21-32]) of 257 patients who had biopsies and multiparametric MRI detecting it in 77 (30% [24-36]; difference -4·3% [95% CI -8·3% to -0·3]). Combining both tests detected 83 (32% [95% CI 27-38]) of 257 clinically significant cancers as per PROMIS definition 1; of these 83 cancers, six (7% [95% CI 3-15]) were detected exclusively with multiparametric ultrasound, and 17 (20% [12-31]) were exclusively detected by multiparametric MRI (agreement 91·1% [95% CI 86·9-94·2]; κ=0·78 [95% CI 0·69-0·86]). No serious adverse events were related to trial activity. INTERPRETATION: Multiparametric ultrasound detected 4·3% fewer clinically significant prostate cancers than multiparametric MRI, but it would lead to 11·1% more patients being referred for a biopsy. Multiparametric ultrasound could be an alternative to multiparametric MRI as a first test for patients at risk of prostate cancer, particularly if multiparametric MRI cannot be carried out. Both imaging tests missed clinically significant cancers detected by the other, so the use of both would increase the detection of clinically significant prostate cancers compared with using each test alone.

Cost of Increasing Years-of-Life-Gained (YLG) Using Fecal Immunochemical Testing as a Population-Level Screening Model in a Rural Appalachian Population.

PURPOSE: Given the innovation of fecal immunochemical testing (FIT) to detect polyps in the rectum and colon for removal by colonoscopy, it is important to determine the cost per Life-Year Gained (LYG) when using FIT as a population-level screening model. This is particularly true for medically underserved rural populations. Accordingly, the purpose of this study was to make this determination among rural Appalachians experiencing isolation and economic challenges. METHODS: The study occurred in an 8-county area of southeastern Kentucky. Kits were distributed to 1,424 residents. Seven hundred thirty-two kits (51.4%) were completed and returned. A Markov decision-analytic model was developed using PrecisionTree 7.6. FINDINGS: Reactive test results occurred for 144 of the completed kits (19.7%). Thirty-seven colonoscopies were verified, with 15 of these indicating precancerous changes or actual cancer. Program costs were estimated at $461,952, with the average cost per person screened estimated at $324. Cost per LYG was $7,912. CONCLUSIONS: In contrast to an average cost per LYG of $17,200, our findings suggest a highly favorable cost-effectiveness ratio for this population of medically underserved rural residents. Cost-benefit analyses suggest that the screening program begins to yield positive net benefits at the stage when project recipients undergo colonoscopy, suggesting that this is the key step for behavioral intervention and intensified outreach.

Vaccine Effectiveness Against Prevalent Anal and Oral Human Papillomavirus Infection Among Men Who Have Sex With Men-United States, 2016-2018.

BACKGROUND: In the United States, human papillomavirus (HPV) vaccination has been recommended for young adult men who have sex with men (MSM) since 2011. METHODS: The Vaccine Impact in Men study surveyed MSM and transgender women aged 18-26 years in 3 US cities during 2016-2018. Self-collected anal swab and oral rinse specimens were assessed for 37 types of HPV. We compared HPV prevalence among vaccinated and unvaccinated participants and determined adjusted prevalence ratios (aPR) and 95% confidence intervals (CI). RESULTS: Among 1767 participants, 704 (39.8%) self-reported receiving HPV vaccine. Median age at vaccination (18.7 years) was older than age at first sex (15.7 years). Quadrivalent vaccine-type HPV was detected in anal or oral specimens from 475 (26.9%) participants. Vaccine-type HPV prevalence was lower among vaccinated (22.9%) compared with unvaccinated (31.6%) participants; aPR for those who initiated vaccination at age ≤18 years was 0.41 (CI, 0.24-0.57) and at age >18 years was 0.82 (CI, 0.67-0.98). Vaccine effectiveness of at least 1 HPV vaccine dose at age ≤18 years or >18 years was 59% and 18%, respectively. CONCLUSIONS: Findings suggest real-world effectiveness of HPV vaccination among young adult MSM. This effect was stronger with younger age at vaccination.

Gender Disparities in Invited Commentary Authorship in 2459 Medical Journals.

Importance: In peer-reviewed medical journals, authoring an invited commentary on an original article is a recognition of expertise. It has been documented that women author fewer invited publications than men do. However, it is unknown whether this disparity is due to gender differences in characteristics that are associated with invitations, such as field of expertise, seniority, and scientific output. Objective: To estimate the odds ratio (OR) of authoring an invited commentary for women compared with men who had similar expertise, seniority, and publication metrics. Design, Setting, and Participants: This matched case-control study included all medical invited commentaries published from January 1, 2013, through December 31, 2017, in English-language medical journals and multidisciplinary journals. Invited commentaries were defined as publications that cite another publication within the same journal volume and issue. Bibliometric data were obtained from Scopus. Cases were defined as corresponding authors of invited commentaries in a given journal during the study period. Controls were matched to cases based on scientific expertise by calculating a similarity index for abstracts published during the same period using natural language processing. Data analyses were conducted from March 13, 2019, through May 3, 2019. Exposure: Corresponding or sole author gender was predicted from author first name and country of origin using genderize.io. Main Outcomes and Measures: The OR for gender was estimated after adjusting for field of expertise, publication output, citation impact, and years active (ie, years since first publication), with an interaction between gender and years active. Results: The final data set included 43 235 cases across 2549 journals; there were 34 047 unique intraciting commentary authors, among whom 9072 (26.6%) were women. For researchers who had been active for the median of 19 years, the odds of invited commentary authorship were 21% lower for women (OR, 0.79 [95% CI, 0.77-0.81]; P < .001) compared with men who had similar scientific expertise, number of publications, and citation impact. For every decile increase in years active, the OR decreased by a factor of 0.97 (95% CI, 0.96-0.98; P < .001). Conclusions and Relevance: In this case-control study, women had lower odds of authoring invited commentaries than their male peers. This disparity was larger for senior researchers. Journal editors could use natural language processing of published research to widen and diversify the pool of experts considered for commentary invitations.

Colorectal Cancer Screening in African American HOPE VI Public Housing Residents.

This study explores whether colorectal cancer screening outreach via home visits and follow-up calls is effective among public housing African American residents. It reports on the proportion of returned Fecal Immunochemical Test kits, on the characteristics of study participants, and on their primary reasons for returning the kit. By conducting home visits and follow-up calls, our colorectal cancer-screening outreach resulted in a higher Fecal Immunochemical Test kit return rate than anticipated. Findings suggest that a more personalized outreach approach can yield higher colorectal cancer-screening rates among urban minority populations, which are at higher risk to be diagnosed with late-stage colorectal cancer.

Unraveling the molecular mechanisms of color expression in anthocyanins.

Anthocyanins are a broad family of natural dyes, increasingly finding application as substitutes for artificial colorants in the food industry. In spite of their importance and ubiquity, the molecular principles responsible for their extreme color variability are poorly known. We address these mechanisms by computer simulations and photoabsorption experiments of cyanidin-3-O-glucoside in water solution, as a proxy for more complex members of the family. Experimental results are presented in the range of pH 1-9, accompanied by a comprehensive systematic computational study across relevant charge states and tautomers. The computed spectra are in excellent agreement with the experiments, providing unprecedented insight into the complex behavior underlying color expression in these molecules. Besides confirming the importance of the molecule's charge state, we also unveil the hitherto unrecognized role of internal distortions in the chromophore, which affect its degree of conjugation, modulating the optical gap and in turn the color. This entanglement of structural and electronic traits is also shared by other members of the anthocyanin family (e.g. pelargonidin and delphinidin) highlighting a common mechanism for color expression across this important family of natural dyes.

Role of MRI in planning radical prostatectomy: what is the added value?

INTRODUCTION: The goal of radical prostatectomy is to eradicate oncological disease while achieving the best possible functional outcomes. In this regard, nerve sparing offers a greater chance of recovering potency after surgery. Accurately locating prostate cancer foci is instrumental for identifying good candidates for this approach whilst maintaining safe oncological margins. In addition to this, the length of membranous urethra is an independent predictor of time to, and extent of, continence recovery. The introduction of Mp-MRI allows visualising malignant tissue within the prostate gland, which could lead to image-directed surgery planning as with other solid-organ cancers such as kidney, pancreas, breast or testes. METHODS: A narrative review of the available literature was performed. RESULTS: Mp-MRI demonstrated moderate sensitivity and high specificity to detect extra-capsular extension, seminal vesicle involvement or T3 stage. Measurements of membranous urethral length have shown to be useful in predicting probability of achieving continence after surgery. Furthermore, image-guided surgery has shown to be accurate to determine surgical planes to safely preserve neurovascular bundles. CONCLUSION: The use of Mp-MRI for pre-surgical planning introduces a new scenario where the previously homogeneous radical prostatectomy can be tailored to suit patient and tumour features. This has the potential to improve functional outcomes whilst not compromising on surgical margins. Moreover, the introduction of Mp-MRI increases the ability to predict functional outcomes after surgery and allows for a more accurate local staging. This in turn provides more information to both patients and clinicians in the decision-making process regarding treatment.

Risk Factors for Oral Human Papillomavirus Infection Among Young Men Who Have Sex With Men-2 Cities, United States, 2012-2014.

BACKGROUND: Men who have sex with men (MSM) are at risk for cancers attributable to human papillomavirus (HPV), including oropharyngeal cancer. Human papillomavirus vaccination is recommended for US MSM through age 26 years. Oral HPV infection is associated with oropharyngeal cancer. We determined oral HPV prevalence and risk factors among young MSM. METHODS: The Young Men's HPV study enrolled MSM aged 18 through 26 years from clinics in Chicago and Los Angeles during 2012 to 2014. Participants self-reported demographics, sexual behaviors, vaccination and human immunodeficiency virus (HIV) status. Self-collected oral rinse specimens were tested for HPV DNA (37 types) by L1-consensus PCR. We calculated adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for risk factors associated with oral HPV among participants not previously vaccinated. RESULTS: Oral HPV was detected in 87 (9.4%) of 922; 9-valent vaccine types were detected in 37 (4.0%) of 922. Among HIV-positive participants, 17 (19.3%) of 88 had oral HPV detected. Oral HPV was more prevalent among those reporting first sex at 18 years of age or younger (aPR, 2.44; 95% CI, 1.16-5.12); HIV infection (aPR, 1.99; 95% CI, 1.14-3.48); greater than 5 sex partners within the past month (aPR, 1.93; 95% CI, 1.13-3.31); performing oral sex on greater than 5 partners within the last 3 months (aPR, 1.87; 95% CI, 1.12-3.13); and having greater than 5 male sex partners within the last 3 months (aPR, 1.76; 95% CI, 1.08-2.87). Only 454 (49.2%) of 922 were aware that HPV can cause oropharyngeal cancers. CONCLUSIONS: Many oral HPV infections were with types targeted by vaccination. Oral HPV infections were significantly associated with HIV and sexual behaviors. Fewer than half of participants were aware that HPV could cause oropharyngeal cancer.

Identifying Communication Barriers to Colorectal Cancer Screening Adherence among Appalachian Kentuckians.

Utilizing data from 40 in-depth interviews, this article identifies both barriers and facilitators to colorectal screening guideline adherence among Appalachian Kentucky adults recruited through a community-based research network. Key findings identify (a) varying levels of knowledge about screening guidelines, (b) reticence to engage in screening processes, and (c) nuanced communication with healthcare providers and family members regarding screening adherence. What participants knew about the screening process was often derived from personal stories or recalled stories from family members about their screening experiences. Reticence to engage in screening processes reflected reports of cumbersome preparation, privacy issues, embarrassment, medical mistrust, fear of receiving a cancer diagnosis, and lack of symptoms. Participants cited many ways to enhance patient-centered communication, and the findings from this study have implications for health communication message design and communication strategies for healthcare practices in Appalachian Kentucky clinics.

Management of patients brought in by ambulance to the emergency department: role of the Advanced Musculoskeletal Physiotherapist.

Objective The aim of the present study was to evaluate the role of the Advanced Musculoskeletal Physiotherapist (AMP) in managing patients brought in by ambulance to the emergency department (ED). Methods This study was a dual-centre observational study. Patients brought in by ambulance to two Melbourne hospitals over a 12-month period and seen by an AMP were compared with a matched group seen by other ED staff. Primary outcome measures were wait time and length of stay (LOS) in the ED. Results Data from 1441 patients within the Australasian Triage Scale (ATS) Categories 3-5 with musculoskeletal complaints were included in the analysis. Subgroup analysis of 825 patients aged ≤65 years demonstrated that for Category 4 (semi-urgent) patients, the median wait time to see the AMP was 9.5min (interquartile range (IQR) 3.25-18.00min) compared with 25min (IQR 10.00-56.00min) to see other ED staff (P ≤ 0.05). LOS analysis was undertaken on patients discharged home and demonstrated that there was a 1.20 greater probability (95% confidence interval 1.07-1.35) that ATS Category 4 patients managed by the AMP were discharged within the 4-hour public hospital target compared with patients managed by other ED staff: 87.04% (94/108) of patients managed by the AMPs met this standard compared with 72.35% (123/170) of patients managed by other ED staff (P=0.002). Conclusions Patients aged ≤65 years with musculoskeletal complaints brought in by ambulance to the ED and triaged to ATS Category 4 are likely to wait less time to be seen and are discharged home more quickly when managed by an AMP. This study has added to the evidence that AMPs improve patient flow in the ED, freeing up time for other ED staff to see higher-acuity, more complex patients. What is known about the topic? There is a growing body of evidence establishing that AMPs improve the flow of patients presenting with musculoskeletal conditions to the ED through reduced wait times and LOS and, at the same time, providing good-quality care and enhanced patient satisfaction. What does this paper add? Within their primary contact capacity, AMPs also manage patients who are brought in by ambulance presenting with musculoskeletal conditions. To the authors' knowledge, there is currently no available literature documenting the performance of AMPs in the management of this cohort of patients. What are the implications for practitioners? This study has added to the body of evidence that AMPs improve patient flow in the ED and illustrates that AMPs, by seeing patients brought in by ambulance, are able to have a positive impact on the pressures increasingly facing the Victorian Ambulance Service and emergency hospital care.

Self-collected vaginal swabs for HPV screening: An exploratory study of rural Black Mississippi women.

OBJECTIVES: To determine the post-procedure acceptability of self-collecting a vaginal swab for HPV testing among a highly impoverished and geographically isolated population of medically underserved Black women residing in the Mississippi Delta. Further, to test correlates of reporting that self-collection is preferred over Pap testing. Finally, to determine the prevalence of any of 13 high-risk HPV types among this population and the correlates of testing positive. METHODS: Eighty-eight women were recruited from two churches located in different towns of the Mississippi Delta. After completing a survey, women were provided instructions for self-collecting a cervico-vaginal swab and completing a post-collection survey. Specimens were tested for 13 oncogenic HPV types. Due to the exploratory nature of the study, significance was defined by a 0.15 alpha-level. RESULTS: Comfort levels with self-collection were high: 78.4% indicated a preference for self-collecting a specimen compared to Pap testing. Overall, 24 women (28.7%) tested positive for one or more of the 13 HPV types. Significant associations with testing positive were found for women having sex with females (P = 0.09), those never having an abnormal Pap (P = 0.06), younger women (P = 0.10), those with greater fatalism scores (P = 0.006), and those having less trust in doctors (P = 0.001). CONCLUSIONS: Black rural women from the deep-south are generally comfortable self-collecting cervico-vaginal swabs for HPV testing. Given that nearly 30% tested positive for oncogenic HPV, and that fatalism as well a lack of trust in doctors predicted prevalence, a reasonable screening alternative to Pap testing may be community-based testing for HPV using self-collected vaginal swabs.

Correlates of Community-Based Colorectal Cancer Screening in a Rural Population: The Role of Fatalism.

OBJECTIVE: One largely unexplored barrier to colorectal cancer (CRC) screening is fatalistic beliefs about cancer. The purpose of this study was to identify correlates of ever having endoscopy screenings for CRC and to determine whether fatalism plays a unique role. Because evidence suggests that cancer-associated fatalistic beliefs may be particularly common among rural Americans, the study was conducted in a medically underserved area of rural Appalachia.  METHODS: Rural residents (N = 260) between 51 and 75 years of age, from a medically underserved area of Appalachia, Kentucky, were recruited for a cross-sectional study. The outcome measure was assessed by a single item asking whether participants ever had a colonoscopy or flexible sigmoidoscopy. Demographic and health-related correlates of this outcome were selected based on past studies of rural populations. A single item assessed perceptions of fatalism regarding CRC. Age-adjusted analyses of correlates testing significant at the bivariate level were conducted.  RESULTS: The analytic sample was limited to 135 rural residents indicating they had ever had CRC endoscopy and 107 indicating never having endoscopy. In age-adjusted analyses, only the measure of fatalism had a significant association with having endoscopy. Those endorsing the statement pertaining to fatalism were 2.3 times more likely (95% CI = 1.24-4.27, P = .008) than the remainder to indicate never having endoscopy.  CONCLUSIONS: A community-based approach to the promotion of endoscopy for CRC screening could focus on overcoming CRC-associated fatalism, thereby potentially bringing more unscreened people to endoscopy clinics.

An Interactive, Mobile-Based Tool for Personal Social Network Data Collection and Visualization Among a Geographically Isolated and Socioeconomically Disadvantaged Population: Early-Stage Feasibility Study With Qualitative User Feedback.

BACKGROUND: Personal social networks have a profound impact on our health, yet collecting personal network data for use in health communication, behavior change, or translation and dissemination interventions has proved challenging. Recent advances in social network data collection software have reduced the burden of network studies on researchers and respondents alike, yet little testing has occurred to discover whether these methods are: (1) acceptable to a variety of target populations, including those who may have limited experience with technology or limited literacy; and (2) practical in the field, specifically in areas that are geographically and technologically disconnected, such as rural Appalachian Kentucky. OBJECTIVE: We explored the early-stage feasibility (Acceptability, Demand, Implementation, and Practicality) of using innovative, interactive, tablet-based network data collection and visualization software (OpenEddi) in field collection of personal network data in Appalachian Kentucky. METHODS: A total of 168 rural Appalachian women who had previously participated in a study on the use of a self-collected vaginal swab (SCVS) for human papillomavirus testing were recruited by community-based nurse interviewers between September 2013 and August 2014. Participants completed egocentric network surveys via OpenEddi, which captured social and communication network influences on participation in, and recruitment to, the SCVS study. After study completion, we conducted a qualitative group interview with four nurse interviewers and two participants in the network study. Using this qualitative data, and quantitative data from the network study, we applied guidelines from Bowen et al to assess feasibility in four areas of early-stage development of OpenEddi: Acceptability, Demand, Implementation, and Practicality. Basic descriptive network statistics (size, edges, density) were analyzed using RStudio. RESULTS: OpenEddi was perceived as fun, novel, and superior to other data collection methods or tools. Respondents enjoyed the social network survey component, and visualizing social networks produced thoughtful responses from participants about leveraging or changing network content and structure for specific health-promoting purposes. Areas for improved literacy and functionality of the tool were identified. However, technical issues led to substantial (50%) data loss, limiting the success of its implementation from a researcher's perspective, and hindering practicality in the field. CONCLUSIONS: OpenEddi is a promising data collection tool for use in geographically isolated and socioeconomically disadvantaged populations. Future development will mitigate technical problems, improve usability and literacy, and test new methods of data collection. These changes will support goals for use of this tool in the delivery of network-based health communication and social support interventions to socioeconomically disadvantaged populations.

Applying modern psychometric techniques to melodic discrimination testing: Item response theory, computerised adaptive testing, and automatic item generation.

Modern psychometric theory provides many useful tools for ability testing, such as item response theory, computerised adaptive testing, and automatic item generation. However, these techniques have yet to be integrated into mainstream psychological practice. This is unfortunate, because modern psychometric techniques can bring many benefits, including sophisticated reliability measures, improved construct validity, avoidance of exposure effects, and improved efficiency. In the present research we therefore use these techniques to develop a new test of a well-studied psychological capacity: melodic discrimination, the ability to detect differences between melodies. We calibrate and validate this test in a series of studies. Studies 1 and 2 respectively calibrate and validate an initial test version, while Studies 3 and 4 calibrate and validate an updated test version incorporating additional easy items. The results support the new test's viability, with evidence for strong reliability and construct validity. We discuss how these modern psychometric techniques may also be profitably applied to other areas of music psychology and psychological science in general.

Impaired Maintenance of Interpersonal Synchronization in Musical Improvisations of Patients with Borderline Personality Disorder.

Borderline personality disorder (BPD) is a serious and complex mental disorder with a lifetime prevalence of 5.9%, characterized by pervasive difficulties with emotion regulation, impulse control, and instability in interpersonal relationships and self-image. Impairments in interpersonal functioning have always been a prominent characteristic of BPD, indicating a need for research to identify the specific interpersonal processes that are problematic for diagnosed individuals. Previous research has concentrated on self-report questionnaires, unidirectional tests, and experimental paradigms wherein the exchange of social signals between individuals was not the focus. We propose joint musical improvisation as an alternative method to investigate interpersonal processes. Using a novel, carefully planned, ABA' accompaniment paradigm, and taking into account the possible influences of mood, psychotropic medication, general attachment, and musical sophistication, we recorded piano improvisations of 16 BPD patients and 12 matched healthy controls. We hypothesized that the insecure attachment system associated with BPD would be activated in the joint improvisation and manifest in measures of timing behavior. Results indicated that a logistic regression model, built on differences in timing deviations, predicted diagnosis with 82% success. More specifically, over the course of the improvisation B section (freer improvisation), controls' timing deviations decreased (temporal synchrony became more precise) whereas that of the patients with BPD did not, confirming our hypothesis. These findings are in accordance with previous research, where BPD is characterized by difficulties in attachment relationships such as maintaining strong attachment with others, but it is novel to find empirical evidence of such issues in joint musical improvisation. We suggest further longitudinal research within the field of music therapy, to study how recovery of these timing habits are related to attachment experiences and interpersonal functioning in general.

Promoting Teen Contraceptive Use by Intervention With Their Mothers.

INTRODUCTION: The purpose of this pilot study was to test a community outreach model designed to help mothers in a rural, medically underserved area navigate their teen daughters to health department services for long-acting reversible contraception (LARC) or alternative contraception. METHODS: The pilot study used a single-group, post-test only design. Mothers of teen daughters (N=142) received a 1-hour, one-to-one intervention session (in outreach settings) from Community Liaisons. Mothers received training on how to communicate with their daughters about LARC and other contraceptive methods. Data were collected from June through October 2014, and analyzed in September 2015. RESULTS: The authors re-contacted 104 of 142 mothers enrolled in the study, achieving a 73.2% retention rate. Of these, 12.5% had daughters receiving LARC. An additional 11.0% had daughters with health department-verified initiation of birth control pills. Only one correlate-whether a mother believed her daughter was having sex-was associated with receiving either LARC or birth control pills. Among those indicating they knew their daughters were having sex, 31.7% of the daughters received LARC/birth control pills. By contrast, among mothers not indicating they knew their daughters were having sex, only 2.9% had daughters receiving LARC or birth control pills. CONCLUSIONS: Findings suggest that an outreach-based program delivered directly to mothers of teen daughters may be a highly effective method for enhancing service utilization of LARC and the initiation of birth control pill use in a rural, medically underserved area.

Lay Epistemology of Breast Cancer Screening Guidelines Among Appalachian Women.

Recent changes to the U.S. Preventive Services Task Force guidelines for breast cancer screening have contributed to increased patient uncertainty regarding the timing and appropriateness of screening behaviors. To gain insight into the lay epistemology of women regarding breast cancer screening practices, we conducted in-depth, face-to-face interviews with 24 adult women living in a medically underserved Appalachian region. We found that women were unaware of breast cancer screening guidelines (i.e., start age, frequency, stop age). Qualitative analysis revealed two lay epistemological narratives establishing (a) uncertain knowledge and ambiguity about breast cancer screening guidelines but certain knowledge of other women's experiences with breast cancer diagnoses, and (b) feelings of knowing one's own body best and seeing the value in "overscreening" to save even one life. Our findings have theoretical and practical implications for scholars and practitioners seeking to improve knowledge or behavior regarding adherence to breast cancer screening recommendations.
