Randomised controlled trial of the short-term effects of OROS-methylphenidate on ADHD symptoms and behavioural outcomes in young male prisoners with attention-deficit/hyperactivity disorder (CIAO-II)
Background
Attention-deficit/hyperactivity disorder (ADHD) is a highly prevalent disorder, seen in 20â30% of young adult prisoners. Pharmacoepidemiological studies, a small randomised controlled trial and open trial data of methylphenidate suggest clinically significant reductions in ADHD symptoms, emotional dysregulation, disruptive behaviour and increased engagement with educational activities. Yet, routine treatment of ADHD in offenders is not yet established clinical practice. There is continued uncertainty about the clinical response to methylphenidate (MPH), a first-line treatment for ADHD, in offenders, who often present with an array of complex mental health problems that may be better explained by states of inattentive, overactive, restless and impulsive behaviours. To address this problem, we will conduct an efficacy trial to establish the short-term effects of osmotic-controlled release oral delivery system (OROS)-methylphenidate (Concerta XL), an extended release formulation of MPH, on ADHD symptoms, emotional dysregulation and behaviour.
Methods
This study is a parallel-arm, randomised, placebo-controlled trial of OROS-MPH on ADHD symptoms, behaviour and functional outcomes in young male prisoners aged 16â25, meeting Diagnostic and Statistical Manual of Mental Disorders, fifth edition criteria for ADHD. Participants are randomised to 8 weeks of treatment with OROS-MPH or placebo, titrated over 5âweeks to balance ADHD symptom improvement against side effects. Two hundred participants will be recruited with a 1:1 ratio of drug to placebo. The primary outcome is change in level of ADHD symptoms after 8 weeks of trial medication.
Discussion
Potential benefits include improvement in ADHD symptoms, emotional dysregulation, attitudes towards violence and critical incidents and increased engagement with educational and rehabilitation programmes. Demonstrating the efficacy and safety of MPH on ADHD symptoms and associated impairments may provide the data needed to develop effective healthcare pathways for a significant group of young offenders. Establishing efficacy of MPH in this population will provide the foundation needed to establish long-term effectiveness studies with the potential for demonstrating significant reductions in criminal behaviour and improved health-economic outcomes
A Practical Theory for Music Analysis: Principles, Categories, Extensions.
This project examines two types of music analysisârhythmic reduction and Schenkerian graphingâby defining, exploring, and extending categories that frame these activities. Part One begins by describing rhythmic reduction in a general way, as a product that embodies three basic categories: âsound like the piece,â âpreserve its essentials,â and âfit in a proposed environment.â By choosing our categories to be concrete yet flexible, they not only provide convenient focal points for discussion; they also allow for the inclusion of a wide variety of musical content.
Part One continues with a description of Schenkerian graphing in terms of its own categories: âtones,â âranking,â âgrouping,â and âstructural levels.â These categories are necessary because of the unique nature of Schenkerian analysis. Part One finishes with a discussion of analytical rhythmic reductions, focusing on types of information that tend to inform the creation of a Schenkerian graph. The results of two case studies show that while analytical reductions provide clarity in the visual representation, they also have difficulty providing deeper insight into issues of ranking, grouping, and structural levels, often because of the need to preserve the metrical framework and their generally low level of abstraction.
Part Two examines the arenas of counterpoint, harmony, and melody from two distinct categorical perspectives. The first examines the CORE of each area of study, its âcontext,â âobjects,â ârelationships,â and âeffects.â This set of categories helps frame each subject in more common or recognizable terms. The category of ârelationshipsâ is perhaps the most intriguing, as it often highlights aspects that are difficult to represent explicitly in a Schenkerian graph. Following this investigation, certain aspects of these arenas are translated into the four categories of Schenkerian graphing stated earlier.
Part Three considers how the boundaries of our categories for Schenkerian graphs may be stretched even further, exploring the inclusion of elements from transformation theory and set theory. In the end, this study will form some reasonably defensible statements as to why graphs using this type of content may âsound like the pieceâ and âpreserve certain essentialsâ of a proposed viewpoint in this environment of fit.PHDMusic: TheoryUniversity of Michigan, Horace H.

Advances in the management of upper tract urothelial carcinoma: improved endoscopic management through better diagnostics
As a rare disease, the management of upper tract urothelial carcinoma (UTUC) continues to evolve. While radical nephroureterectomy remains the gold standard, there is a growing desire to pursue nephron-sparing approaches through endoscopic management, particularly for low-risk disease or in the setting of imperative indications. A particular challenge for those undertaking endoscopic management is appropriate grading and staging of tumors, and thereby appropriate patient selection. In this review we will cover the current state of diagnostics for UTUC as well as highlight the challenges in accurate diagnosis. Additionally, we will focus on emerging technologies to aid in optimizing diagnostic accuracy in UTUC. This will include discussion of narrow band imaging, photodynamic diagnosis, optical coherence tomography, and confocal laser endomicroscopy
Same-session bilateral ureteroscopy: safety and outcomes.
OBJECTIVE: To assess the complications and outcomes associated with same-session bilateral ureteroscopy in a tertiary referral center, as same-session bilateral ureteroscopy for stone disease has been critiqued for the theoretical risk of injury to both ureters with subsequent risk to renal function.
METHODS: We retrospectively reviewed all cases of bilateral ureteroscopy performed for urolithiasis by a single surgeon at out institution between 2009 and 2014. These were compared to a prospective unilateral ureteroscopy database.
RESULTS: There were 117 same-session bilateral ureteroscopic procedures performed in 113 patients totaling 234 ureteroscopies. A flexible ureteroscope was used in 228 ureters (97.4%), and 6 (2.6%) were semirigid only. Ureteral dilators were required in 8 (6.8%) cases. Pre-stenting was performed in 23 (19.6%) patients. Short-term complications were observed following 19 (16.2%) procedures, including 11 (9.4%) Clavien I, 4 (3.4%) Clavien II, and 4 (3.4%) Clavien III. Of the 84 (71.8%) patients who completed a 6-week follow-up, there were no long-term complications. Stone-free rates were 91.4% for patients imaged with abdominal x-ray and ultrasound, and 84.2% for those imaged with computed tomography scans. Neither complications nor re-admissions were significantly different in the unilateral group. Median length of follow-up for the entire cohort was 2.8 years (range 0-7 years).
CONCLUSION: Bilateral ureteroscopy can be performed safely with short-term complications, consistent with published literature. We found no long-term complications and high stone-free rates. Bilateral ureteroscopy in a single procedure represents a viable standard of care for patients with bilateral stone disease
Synchronous melanosis of upper and lower urinary tract
Urothelial melanosis is an exceptionally rare diagnosis, with less than 25 cases being reported in the literature. Melanosis of the urothelium is characterized by abnormal melanin deposition within tissues, producing a black, velvety appearance to the urothelial mucosa. We present a 67-year-old male undergoing cystoscopy during a routine percutaneous nephrolithotomy (PCNL), who was found to have diffuse bladder melanosis extending up the ureter and into the renal pelvis. To our knowledge, this is the first reported case of synchronous melanosis of upper and lower urinary tract
Over-the-Counter Alkali Agents to Raise Urine pH and Citrate Excretion: A Prospective Crossover Study in Healthy Adults
OBJECTIVE: To assess the effect of 2 over-the-counter alkalizing agents on 24 hour urinary parameters.
MATERIALS AND METHODS: Ten healthy volunteers without a history of kidney stones were recruited to complete a baseline 24 hour urinalysis with a 4 day diet inventory. Participants then maintained the same diet on either LithoLyte (20 mEq 2 times per day) or KSPtabs (1 tablet 2 times per day) and submitted another 24 hour urinalysis. The process was repeated with the other supplement. Urinary alkali parameters were compared to baseline, and side effects were elicited with a questionnaire.
RESULTS: LithoLyte intake resulted in a non-significant increase in citrate (597-758 mg/day, P =.058, an increase in urine pH (6.46-6.66, P =.028), and a decrease in urine ammonium (41-36 mmol/day, P =.005) compared to baseline. KSPtabs resulted in an increase in citrate (597-797 mg/day, P =.037) and urine pH (6.46-6.86, P =.037), with a non-significant decrease in ammonium (41-34 mmol/day, P =.059). No significant differences were seen comparing urinary analytes between LithoLyte and KSPtabs. With Litholyte, no side effects, mild, moderate, and severe side effects were seen in 50%, 40%, 10%, and 0%, respectively. With KSPtabs, rates were 60%, 20%, 10%, and 10%, respectively.
CONCLUSION: In healthy participants without a history of kidney stones, LithoLyte and KSPtabs are effective over-the-counter alkali supplements, with a similar side effect profile to prescription potassium citrate
