How Active is Active Surveillance? Intensity of Follow-Up During Active Surveillance for Prostate Cancer in the United States
Loeb, Stacy; Walter, Dawn; Curnyn, Caitlin; Gold, Heather T; Lepor, Herbert; Makarov, Danil V
PURPOSE: While major prostate cancer active surveillance (AS) programs recommend repeat testing such as PSA and prostate biopsy, compliance with such testing is unknown. Our objective was to determine whether men in the community receive the same intensity of AS testing as in prospective AS protocols. MATERIALS AND METHODS: We performed a retrospective cohort study of men aged >/=66 in the SEER-Medicare database diagnosed with prostate cancer from 2001-2009 who did not receive curative therapy in the year after diagnosis with >/=1 post-diagnosis prostate biopsy. We used multivariable-adjusted Poisson regression to determine the association between frequency of AS testing with patient demographics and clinical features. Among 1349 men with =5 years follow-up, we determined the proportion undergoing testing of the intensity recommended by the Sunnybrook and PRIAS programs (>/=14 PSA and >/=2 biopsy), and at Johns Hopkins (>/=10 PSA and >/=4 biopsy). RESULTS: Among 5192 patients undergoing AS, >80% had >/=1 PSA test per year but <13% received biopsy beyond the first 2 years. MRI was rarely used during the study period. On multivariable analysis, recent diagnosis and higher income were associated with higher frequency of surveillance biopsy, while older age and greater comorbidity were associated with fewer biopsies. African American men underwent fewer PSAs but similar numbers of biopsies. During 5 years of AS, only 11.1% and 5.0% met the testing standards of the Sunnybrook/PRIAS and Johns Hopkins programs. CONCLUSIONS: In the community, very few elderly men receive the intensity of AS testing recommended by major prospective AS programs.; Key of Definition for Abbreviations: AS=active surveillance, PCa=prostate cancer, PSA=prostate specific antigen, MRI=magnetic resonance imaging, NCCN=National Comprehensive Cancer Network, PRIAS=Prostate Cancer Research International Active Surveillance, WW=watchful waiting.

Activity, content, contributors, and influencers of the twitter discussion on urologic oncology
Borgmann, Hendrik; Loeb, Stacy; Salem, Johannes; Thomas, Christian; Haferkamp, Axel; Murphy, Declan G; Tsaur, Igor
OBJECTIVES: To analyse the activity, content, contributors, and influencers of the Twitter discussion on urologic oncology. MATERIALS AND METHODS: We performed a comprehensive quantitative and qualitative Twitter analysis for the hashtags #prostatecancer, #bladdercancer, #kidneycancer, and #testicularcancer. Symplur was used to analyse activity over different time periods and the top influencers of the Twitter discussion. Tweet Archivist and Twitonomy analysis tools were used to assess characteristics of content and contributors. RESULTS: Twitter discussion on urologic oncology in 2014 contained 100,987 tweets created by 39,326 participants. Mean monthly tweet activity was 6,603+/-2,183 for #prostatecancer, 866+/-923 for #testicularcancer, 457+/-477 for #bladdercancer and 401+/-504 for #kidneycancer. Twitter activity increased by 41% in 2013 and by 122% in 2014. The content analysis detected awareness, cancer, and risk as frequently mentioned words in urologic oncology tweets. Prevalently used related hashtags were the general hashtag #cancer, awareness hashtags, and the respective cancer/urology tag ontology hashtags. Contributors originated from 41 countries on 6 continents and had a mean of 5,864+/-4,747 followers. They tweeted from platforms on exclusively mobile devices (39%) more frequently than from desktop devices (29%). Health care organizations accounted for 58% of the top influencers in all cancers. The largest proportion of physicians were among the #prostatecancer and #kidneycancer (each 9%) influencers and individual contributors were most frequent in the discussion on #kidneycancer (57%) and #testicularcancer (50%). CONCLUSION: There is a significant and growing activity in the Twitter discussion on urologic oncology, particularly on #prostatecancer. The Twitter discussion is global, social, and mobile, and merits attention of stakeholders in health care as a promising communication tool.

Beyond prostate-specific antigen: utilizing novel strategies to screen men for prostate cancer
Loeb, Stacy; Lilja, Hans; Vickers, Andrew
PURPOSE OF REVIEW:The purpose of this article is to review blood and urine tests that are currently available and under investigation for a role in prostate cancer screening and detection. RECENT FINDINGS:Compared with total prostate-specific antigen (PSA) alone, its combination with percentage free-to-total PSA contributes greater specificity for prostate cancer, and is a component of two newer blood tests called the 4kScore and Prostate Health Index. All three tests improve the prediction of high-grade disease and are commercially available options to aid in initial or repeat prostate biopsy decisions. PCA3 is a urinary marker that is currently available for repeat prostate biopsy decisions. Although PCA3 alone has inferior prediction of clinically significant disease and requires collection of urine after digital rectal examination, it may be combined with other clinical variables or other urine markers like TMPRSS2:ERG to improve performance. Little data are available to support a role for single nucleotide polymorphisms or other investigational markers in early detection. SUMMARY:Several commercially available blood and urine tests have been shown to improve specificity of PSA for high-grade prostate cancer. Use of such tests would decrease unnecessary biopsy and overdiagnosis of indolent disease. Biopsy of men with moderately elevated PSA without use of such a reflex test should be discouraged.

Design of the NIDA clinical trials network validation study of tobacco, alcohol, prescription medications, and substance use/misuse (TAPS) tool
Wu, Li-Tzy; McNeely, Jennifer; Subramaniam, Geetha A; Sharma, Gaurav; VanVeldhuisen, Paul; Schwartz, Robert P
BACKGROUND: Substance use and its associated use disorders are under-detected and under-treated in primary care. There is a need for a clinically useful brief screening and assessment instrument to identify primary care patients with substance use, sub-threshold substance use disorder (SUD), and SUD to facilitate brief intervention and treatment. METHODS: We describe the design of the recently completed National Drug Abuse Treatment Clinical Trials Network's tobacco, alcohol, prescription medications, and substance use/misuse screen and brief assessment tool validation study. Study aims included to: develop a 2-stage screening and brief assessment tool (TAPS Tool) to detect substance use, problem use, and SUD among adult primary care patients; examine the validity of both the screen component and the TAPS Tool by comparing them to reference standard screening and assessment measures of no use, problem use, and SUD; and determine the feasibility and acceptability of the self-administration and interviewer-administration of the tool. The design included a pilot testing phase (n=30) and the main study of 2000 adult primary care participants who were randomly assigned in counter-balanced order to have the interviewer-administration or the self-administration of the TAPS Tool followed by the other administration format. Participants' views of feasibility, acceptability and preference for format of self-administration versus interviewer-administration of the TAPS Tool were assessed. Criterion measures of use and DSM-5 SUDs were administered. DISCUSSION: The TAPS Tool study builds on prior work to develop a 2-stage clinical tool for facilitating the adoption of screening, brief assessment and treatment for SUDs in primary care.

Incidence and factors associated with injuries among adolescent players in an amateur soccer tournament in Nigeria
Olumide, Adesola; Ajide, Kemisola
BACKGROUND:The study was conducted to determine the incidence and risk factors associated with injuries among adolescents participating in an amateur soccer tournament in Ibadan, Nigeria. METHODS:A prospective study was conducted among 90 participants (66 players and 24 substitutes) from six all-male teams with each team comprising 11 players. A total of six matches, each lasting 60 minutes (132 player-hours) were played in the tournament. Players were observed during all matches and followed up for up to two weeks after the final match. The association between selected risk factors and injury occurence was assessed using χ2 test. RESULTS:Players mean age was 16.1 (±1.8) years. Twelve (13.3%) of the 90 players were involved in 15 injury events. The injury incidence was 113.6 injuries per 1000 player hours (95% CI: 56.1-171.1) and 12 (80.0%) of all injuries occurred within 15 minutes of the end of each half of the match. Injuries often affected the lower limb 10 (58.8%), and the upper limb 6 (35.3%). Common injuries sustained were abrasions, 11 (64.6%), sprains, 3 (17.6%) and contusions 2 (11.8%). Eighty percent of injuries were due to collision with another player. All injuries were slight to mild as all the injured players returned to practice or games within five days of sustaining the injury. Dominant playing foot (mainly left foot or both feet) was associated with a higher incidence of injuries (χ2=7.321; P=0.018). CONCLUSIONS:Injury incidence was relatively high although injuries were mild. Measures to minimize injuries following player-to-player contact would be beneficial for adolescent soccer players in our study setting.

Discordant reporting of nonmedical opioid use in a nationally representative sample of US high school seniors
Palamar, Joseph J; Shearston, Jenni A; Cleland, Charles M
BACKGROUND: Nonmedical opioid use has become a major public health concern due to increases in treatment admissions, overdoses, and deaths. Use has also been linked to heroin initiation. Reliable data on nonmedical opioid use are needed to continue to inform prevention. OBJECTIVE: To determine the prevalence and correlates of discordant self-report of nonmedical use of opioids in a national sample. METHODS: Utilizing a nationally representative sample of 31,149 American high school seniors in the Monitoring the Future study (2009-2013), discordant responses between self-reported 12-month nonmedical opioid use and self-reported 12-month nonmedical Vicodin and OxyContin use (reporting Vicodin/OxyContin use, but not reporting "opioid" use) were assessed. We also used multivariable logistic regression to determine the characteristics of students who were most likely to provide a discordant response. RESULTS: 37.1% of those reporting nonmedical Vicodin use and 28.2% of those reporting nonmedical OxyContin use did not report overall nonmedical opioid use. Prevalence of nonmedical opioid use (8.3%) would increase when factoring in Vicodin, OxyContin, or both, by 2.8%, 1.3%, and 3.3%, respectively. Females were more likely to provide a discordant response to Vicodin and highly religious students were more likely to provide a discordant response regarding OxyContin use. Those who reported cocaine or nonmedical tranquilizer use were at consistently low odds for discordant responses. Nonmedical amphetamine users were at low odds for providing a discordant Vicodin response. CONCLUSION: Prevalence of nonmedical opioid use may be underreported on some surveys, particularly among specific subpopulations. Further research on the effect of question order and skip-patterns (e.g., "gate" questions) is needed. Reliable data on nonmedical opioid use are needed to continue to accurately inform prevention.

'Cytology-on-a-chip' based sensors for monitoring of potentially malignant oral lesions
Abram, Timothy J; Floriano, Pierre N; Christodoulides, Nicolaos; James, Robert; Kerr, A Ross; Thornhill, Martin H; Redding, Spencer W; Vigneswaran, Nadarajah; Speight, Paul M; Vick, Julie; Murdoch, Craig; Freeman, Christine; Hegarty, Anne M; D'Apice, Katy; Phelan, Joan A; Corby, Patricia M; Khouly, Ismael; Bouquot, Jerry; Demian, Nagi M; Weinstock, Y Etan; Rowan, Stephanie; Yeh, Chih-Ko; McGuff, H Stan; Miller, Frank R; Gaur, Surabhi; Karthikeyan, Kailash; Taylor, Leander; Le, Cathy; Nguyen, Michael; Talavera, Humberto; Raja, Rameez; Wong, Jorge; McDevitt, John T
Despite significant advances in surgical procedures and treatment, long-term prognosis for patients with oral cancer remains poor, with survival rates among the lowest of major cancers. Better methods are desperately needed to identify potential malignancies early when treatments are more effective. OBJECTIVE: To develop robust classification models from cytology-on-a-chip measurements that mirror diagnostic performance of gold standard approach involving tissue biopsy. MATERIALS AND METHODS: Measurements were recorded from 714 prospectively recruited patients with suspicious lesions across 6 diagnostic categories (each confirmed by tissue biopsy -histopathology) using a powerful new 'cytology-on-a-chip' approach capable of executing high content analysis at a single cell level. Over 200 cellular features related to biomarker expression, nuclear parameters and cellular morphology were recorded per cell. By cataloging an average of 2000 cells per patient, these efforts resulted in nearly 13 million indexed objects. RESULTS: Binary "low-risk"/"high-risk" models yielded AUC values of 0.88 and 0.84 for training and validation models, respectively, with an accompanying difference in sensitivity+specificity of 6.2%. In terms of accuracy, this model accurately predicted the correct diagnosis approximately 70% of the time, compared to the 69% initial agreement rate of the pool of expert pathologists. Key parameters identified in these models included cell circularity, Ki67 and EGFR expression, nuclear-cytoplasmic ratio, nuclear area, and cell area. CONCLUSIONS: This chip-based approach yields objective data that can be leveraged for diagnosis and management of patients with PMOL as well as uncovering new molecular-level insights behind cytological differences across the OED spectrum.

Expanding the Oncofertility Workforce: Training Allied Health Professionals to Improve Health Outcomes for Adolescents and Young Adults
Quinn, Gwendolyn P; Woodruff, Teresa K; Knapp, Caprice A; Bowman, Meghan Lorraine; Reinecke, Joyce; Vadaparampil, Susan T
As cancer survivors live longer, fertility and reproductive health become important health concerns. Like other secondary effects of cancer treatment, these anticipated health risks should be addressed before the initiation of cancer treatment. While existing and emerging technologies may prevent or reduce risk of infertility (e.g., sperm, oocyte, embryo, or tissue banking), the lack of a trained workforce knowledgeable about oncology and reproductive health poses a barrier to care. The allied health professional (AHP) is a target of opportunity because of the direct and sustained patient relationships. Thus, developing tailored educational programs for nurses, social workers, psychologists, and physician assistants is an urgent unmet need toward field building. In this report, we outline results from a pilot study evaluating AHP perceptions of an oncology and reproductive health curriculum originally developed for nurses and adapted to meet the needs of several other AHP groups.

Review of fertility preservation issues for young women with breast cancer
Goncalves, Vania; Quinn, Gwendolyn P
It is well documented that cancer treatment may temporarily or permanently impair childbearing potential of young women with breast cancer. Given that many patients have not initiated or completed their families when diagnosed, fertility issues are of utmost importance in this clinical population. This review addresses the importance of incorporating fertility issues into the clinical care of young breast cancer patients, focusing on recent knowledge and counselling practices about fertility-related issues and the complexity of fertility-related decisions in this population. Multiple studies report cancer-related infertility may have serious psychological consequences and reduce Quality of Life for some patients. To guide health care providers and patients regarding appropriate, safe, and cost-effective fertility care for women who desire biological children, several professional organizations have developed clinical practice guidelines. However, the extent to which health professionals use these guidelines and provide timely and appropriate fertility-related information to patients is questionable. Fertility should not be neglected by health care providers and a multidisciplinary team is needed to target fertility issues at diagnosis and into survivorship care, providing timely, clear information that includes support, resources, and appropriate referral to fertility specialists. This information will assist in making well-informed decisions about fertility after breast cancer.

Effects of hookah smoking on indoor air quality in homes
Weitzman, Michael; Yusufali, Afzal Hussein; Bali, Fatma; Vilcassim, M J Ruzmyn; Gandhi, Shashank; Peltier, Richard; Nadas, Arthur; Sherman, Scott; Lee, Lily; Hong, Zhang; Shearston, Jenni; Park, Su Hyun; Gordon, Terry
INTRODUCTION: Hookahs (water pipes) are rapidly increasing in popularity worldwide. Evidence suggests that although perceived as safer than cigarette smoke, hookah smoke may be as, or even more, dangerous as cigarette smoke. METHODS: Air samples from 33 homes-11 where only hookah-smoking occurred, 12 with only cigarettes and 10 with no smoking-were collected to analyse concentrations of particulate matter (PM2.5), black carbon, elemental and organic carbon and carbon monoxide (CO). Air quality was assessed in rooms where smoking occurred and in an adjacent room. RESULTS: Hookah and cigarette smoking impaired home air quality. The rooms in which hookahs were smoked showed the highest concentrations for all pollutants. CO was significantly greater in the rooms where hookahs were smoked than in the cigarette-smoking rooms and the non-smoking households (p<0.05). In addition, CO levels in the rooms adjacent to where hookah was smoked were 2.5-fold to 4-fold greater than those in the smoking and non-smoking rooms of the cigarette homes (p<0.05). PM2.5 levels were also elevated in hookah homes compared to cigarette and non-smoking homes, although not significantly different. CONCLUSIONS: This study, the first of its kind, demonstrates potentially hazardous levels of home air pollution in rooms where hookahs are being smoked as well as in adjacent rooms. These levels were greater than those in cigarette smoking homes, raising concerns about potential negative health effects on all individuals living in homes where hookahs are smoked.
