Abstract
PURPOSE The aim of this study is to examine the rates of clinical actions (CAs) as a result of serial creatinine (SCr) values and to examine postoperative SCr trends to assess the utility of SCr measurements in radical cystectomy (RC) patients. METHODS We performed a retrospective chart review using our institution's database on all patients who underwent radical cystectomy for urothelial carcinoma (UC) from 2009 to 2019. Preoperative and all postoperative inpatient creatinine values were recorded. Minor CAs included fluid boluses, fluid rate changes, and medication changes. Major CAs included OR take-backs for stent repositioning, nephrostomy tube placement, nephrology consultation, and hemodialysis. RESULTS A total of 238 RCs were performed with a resultant 2952 SCr measurements. The median number of SCr measurements per patient was 9 (interquartile range, IQR 7) with median length of hospital stay of 10 days (IQR 9 days). There were 92 minor and 12 major CAs as a result of 3% and 0.44% of SCr measurements, respectively. All major CAs were seen in patients experiencing complicated postoperative course. The median postoperative day with the highest creatinine was day 2. Predictors of postoperative CAs included preoperative renal dysfunction and obesity. CONCLUSION SCr measurements remain a clinically valuable tool in postoperative management. Nonetheless, this present study suggests that prolonged SCr monitoring is of limited clinical utility. As such, discontinuing SCr checks after postoperative day 3 in patients experiencing uncomplicated postoperative course is safe and may lead to both cost savings and decreased patient discomfort.

Abstract
Aim
Cancer treatment targets were halted in the COVID-era due to a major re-organisation of services and coincided with a drop in prostate cancer (PCa) referrals, investigations, and diagnoses. This study measures the impact of the pandemic on a PCa diagnostic pathway in a major cancer centre.
Method
Data was collected during the onset of COVID-19 (March to June 2020) and the same months in 2019 for urgent suspected prostate cancer (USPC) referrals. All referrals, PSA tests, multiparametric MRI's of prostate (mpMRI-P), and TRUS-guided biopsy of the prostate (TBP) were recorded.
Results
USPC referrals reduced by 65% from a mean 315 referrals per month to 110 during the pandemic. During March-June 2019 a total of 10,404 PSA tests were conducted in the healthcare trust, which reduced by 39% during COVID-19. Multiparametric MRI of prostate was reduced by 45%. TRUS biopsies were down by 65%, from a mean of 31 to 11 biopsies per month, with only 3 biopsies being conducted in April 2020.
Conclusions
The reduction in PCa referrals and workload in our centre in the COVID-era has been significant. The uncertainty associated with such a drop in demand poses concerns for meeting future cancer targets when prostate cancer referrals return to baseline.

Abstract
AIMS Long-term or recreational use of ketamine affects the urinary system and can result in ketamine-induced cystitis (KIC). Rodent models of KIC are important to study KIC pathophysiology and are paramount to the future development of therapies for this painful condition. This review aims to provide a summary of rodent models of KIC, focusing on disease induction, experimental methods, and pathological features of the model. METHOD A literature search was performed using the National Center for Biotechnology Information (NCBI) Pubmed database up to March 2021. 20 articles met the inclusion criteria and were finally selected. RESULTS There are considerable variations in the rodent models used for studying KIC in terms of the strain of the animal being used; dose, duration, and route of ketamine administration to induce KIC, and assessment of pathological features. CONCLUSION KIC remains difficult to fully recapitulate in humans. Improved characterization of KIC models and the experimental parameters and meticulous discussion on translational limitations are required to improve the translational value of research using rodent models of KIC.

Abstract
Commonly reported sex trafficking indicators have been disseminated widely by government and non-governmental organizations in trainings aimed to increase identification and referral to resources. However, very little research evaluates such indicators. Drawing from survey responses of 86 social service providers, health care practitioners, and justice system officials in a Midwestern City, this pilot study aimed to examine: (a) the pervasiveness of the commonly reported indicators, (b) the salience of domains of indicators, and (c) the extent to which indicators differ across service populations (U.S.-born minors, U.S.-born adults, foreign born minors, and foreign born adults). The most commonly identified indicators included mental health symptoms of depression (M = 3.82); low self-esteem (M = 3.59); anxiety (M = 3.55); low levels of interpersonal trust (M = 3.52); sense of fear (M = 3.36); feelings of shame or guilt (M =3.34); isolation from family, friends, and communities (M = 3.3); and fear/distrust of law enforcement (M = 3.80). The least commonly identified indicators included exhibiting low English proficiency (M = 1.62), previous history of loitering charges (M = 1.74), presenting false documents (M = 1.85), presence of tattoos or branding (M = 1.89), presenting delayed cognitive development (M = 1.91), being unaware of one's location (M = 1.94), owing large debt (M = 1.95), previous history of prostitution or drug charges (M = 1.98, M = 2.01), and physical evidence of torture (M = 2.07). The mental health domain was identified as especially common among U.S.-born adults (M = 3.07). Criminal justice involvement was identified as less common among foreign-born minors (M = 1.82) and foreign-born adults (M = 1.96). The most commonly identified indicators, according to the service providers, health care workers, and justice system officials who work with them, are inconsistent with many of the indicators that are used frequently across governmental and community trainings. Trainings focusing on diverse case examples of trafficking may be important in strengthening identification of sex trafficked individuals, as well as accounting for regional contexts.

Abstract
Osteogenesis imperfecta (OI) is characterized by bone fragility and increased fracture susceptibility. BMP1 variants have been reported in the rare OI type XIII, specifically referred to herein as BMP1-associated autosomal recessive (AR) OI. We report the clinical presentation and diagnostic evaluation of a patient found to have a novel homozygous variant in BMP1. We also provide an overview of reported BMP1 variants to date, with discussion focusing on the use of bisphosphonate therapy in these patients. A 7-year-old male with speech and motor delay sustained five bilateral tibial fractures with minimal trauma since age 2.5 years. At age 6, he developed severe back pain after a fall. Diffuse spinal osteopenia and multiple vertebral compression fractures (VCF) at T9, L1, L3, and L5 were identified. Total hip BMD was generous (adjusted Z-score* = 1.76), and femoral neck BMD was high (adjusted Z-score* = 2.67). VCFs precluded assessment of lumbar spine BMD. Genetic analysis identified a homozygous missense variant in exon 4 of BMP1 (c.C505T; p.Arg169Cys). Unlike most forms of OI, patients with BMP1-associated AR OI may have normal or paradoxically increased BMD, making BMD and fracture risk correlation difficult. While bisphosphonates (BP) may help reduce recurrent fractures and provide symptomatic relief, the broad phenotypic spectrum and underlying bone pathology, often in the setting of increased BMD, complicate management. HR-pQCT assessment of bone microarchitecture and quality may aid in the decision of BP therapy and subsequent monitoring. Evidence is limited with respect to the effectiveness of BP in this rare form of OI. *Z-score was adjusted for height Z-score.

Abstract
BACKGROUND Due to the COVID-19 pandemic, telephone clinics have been utilised to reduce the risk of transmission. Evidence supporting its quality and safety is required. AIMS Assess the efficacy and safety of telephone clinics in delivering care to established oncology patients and assess patient and health professionals' preference (telephone vs face-to-face clinics). METHODS Retrospective chart audit in the month preceding and month following introduction of telephone clinics at the Gold Coast University hospital and a patient and health professional questionnaire. RESULTS In total, 1212 clinical encounters occurred in the month post the introduction of telephone clinics (vs 1208 encounters prior). There were no statistically significant differences in 24-h (18 vs 22, p = 0.531) or 7-day admissions (50 vs 46, p = 0.665) comparing encounters in the month prior to the introduction of telephone clinics vs the month post, but there was a statistically significant difference in 30-day mortality post systemic therapy in favour of the post-telephone clinic period (7 vs 0 patients, p = 0.008). Of the 222 patients who undertook the questionnaire, 42.3% preferred telephone clinics (95% CI 35.97-48.97), 25.2% preferred face-to-face clinics (95% CI 19.92-31.39) and 32.4% did not prefer one method over another. Of the 24 health professionals who undertook the questionnaire, 70.8% felt patients preferred phone clinics. CONCLUSIONS Generally, patients and clinicians viewed telephone clinics favourably. Nevertheless, a large portion of patients still prefer face-to-face clinics. Services should be tailored to individual preferences. Although there were no 'red flags' in terms of mortality or admission rates, further longitudinal research is required. This article is protected by copyright. All rights reserved.

Abstract
BACKGROUND English youth typically do not sufficiently engage in the types and intensities of physical activity that develop muscular fitness. The aim of this study was to use a combination of qualitative techniques to explore adolescent boys' understanding, perceptions, and experiences of physical activity and the role muscular fitness plays within boys' physically active lifestyles. METHODS Focus group interviews with a write, draw, show, and tell activity were conducted with 32 adolescent boys aged 14-16 years from 3 secondary schools. Three separate sources of data (frequency counts, verbatim transcripts, and visual data) were generated and were pooled together and triangulated. Data were analysed deductively, first using the Youth Physical Activity Promotion model as a thematic framework, and then inductively. RESULTS Physical activity was frequently associated with organised sport, and most boys were unaware of current UK physical activity guidelines. Co-participation was frequently reported as a reinforcing factor to physical activity. CONCLUSIONS There was a perceived lack of opportunity to participate in muscular fitness activities, particularly in school, and knowledge of how to conduct muscular fitness activities was limited. The contribution of physical education was highlighted as being key to facilitating exposure to muscular fitness activities.

Abstract
Background Manual semen assessment (MSA) is a key component in a male’s fertility assessment. Clinicians rely on it to make diagnostic and treatment decisions. When performed manually, this routine laboratory test is prone to variability due to human intervention which can lead to misdiagnosis and consequently over- or under- treatment. For standardisation, continuous training, quality control (QC) programs and pricy Computer-Assisted Sperm Analysis (CASA) systems have been proposed, yet, without resolving intra- and inter-laboratory variability. In response, promising simplified sperm testing devices, able to provide cost-effective point-of-care male infertility diagnosis are prospected as a plausible solution to resolve variability and increase access to sperm testing. Materials and methods A throughout literature research for semen testing, sperm analysis, smart-phone assisted semen analysis, ‘at-home’ semen testing, male infertility, infertility in developing countries, infertility in low- and middle-income countries (LMIC) and quantitative sperm analysis was performed. A total of 14 articles, specific to ‘at-home’ simplified sperm assessment, were included to treat the core subject. Results Continuous training and consistent QC, are sine qua none conditions to achieve accurate and comparable MSA. Compliance does not rule-out variability, nevertheless. Emerging simplified sperm assessment devices are an actual alternative to resolve the lack of standardisation and accessibility to sperm analysis. YO ® , SEEM ® , and ExSeed ® are commercially available, user-friendly smartphone-based devices which can accurately measure volume, sperm concentration (millions/ml) and total motile sperm count. More broadly, by cost-effectiveness, availability, accuracy and convenient application, these devices could effectively select patients for first-line artificial reproduction treatments such as intrauterine insemination. Conclusions Accuracy and cost-effectiveness make smart-phone based sperm testing devices a practical and realistic solution to overcome variability in MSA. Importantly, these tools represent an actual opportunity to standardise and improve male subfertility diagnosis and treatment, especially in LMIC. However, before clinical application is possible, guidelines, further testing with special attention on accuracy in washed sperm, availability, cost-benefit and reliability are required.

Abstract
INTRODUCTION Nonagenarians represent a growing patient population. Herein, we report on the largest cohort of Canadian nonagenarian patients, to our knowledge, with prostate cancer. METHODS A retrospective chart of 44 nonagenarian men diagnosed with localized or metastatic prostate cancer between 2006 and 2019 was performed. Diagnoses were based on pathological specimens or the presence of a high prostate-specific antigen (PSA >20) or abnormal digital rectal exam (DRE) in the setting of metastatic disease on imaging. Patient demographics, presenting complaints, and treatments required were included in the analysis. A descriptive statistical analysis was performed. RESULTS The median patient age at time of referral was 91.1 years (interquartile range [IQR] 90.2-92.9). The median PSA at time of referral was 54.0 (IQR 18.2-142.6). Metastatic disease was present in 55% of patients at time of diagnosis (n=24). Most patients required at least one urological intervention (n=35). There were 56.8% of patients who received androgen deprivation therapy (ADT) as part of their treatment regime (n=25). Half (50%) of patients were managed with androgen receptor axis-targeted agents (ARAT), as well as ADT (n=22). Five patients (11.4%) underwent surgical castration. Death due to any cause was noted in 52.3% of patients (n=23) throughout the study period, with the median age at death being 94.4 years (IQR 92.3-97.0). Death due to prostate cancer was noted in 18.2% of patients (n=8). CONCLUSIONS This study highlights common presenting complaints for nonagenarian patients with prostate cancer and that many require urological intervention despite advanced age. Future studies should address patient-reported quality-of-life outcomes in the nonagenarian population with prostate cancer.

Abstract
AIMS To evaluate the long-term outcomes of sacral neuromodulation (SNM), and patient characteristics that may predict long-term success or complications. METHODS A single-center retrospective cohort study was performed of all patients who underwent SNM testing and implantation. Outcome results, resolution of symptoms, and device removal were reported. Multivariable logistic regression was used to identify predictors of success. Cox proportional hazards model was used to identify predictors for device removal. RESULTS Four hundred and thrity four patients underwent SNM test phase of which 241 (median age 48.0 years, 91.7% [221/241] female) had device implantation and were followed up for median [range] time of 4.0 (3 months-20.5 years) years. Multivariable logistic regression showed that male gender (odds ratio: 0.314; 95% confidence interval: 0.164-0.601, p = .0005) was independently associated with decreased peripheral nerve evaluation success. At final follow-up for patients who originally had device implantation, median (interquartile range) percent of symptoms resolution of all patients was 60.0% (0%-90%) and 69.3% (167/241) had SNM successful outcomes. Cox proportional hazards model showed no difference for time to SNM device removal with respect to patient age, gender, or diagnosis. 69.3% (167/241) patients had at least 1 surgical re-intervention. The most common reason at first surgical re-intervention was lead change only (26.3%, 44/167). CONCLUSION SNM is a minimally invasive procedure with good long-term success rates. There is a high revision rate but overall, SNM has a good safety profile and excellent long-term outcomes.

Abstract
The initial wave of the COVID-19 crisis forced immediate and seismic changes on urological practice, patient care, and education — collateral damage to the upending of societal and global economic norms. Lockdowns and limitations curtailed access to the physical spaces of the clinic and operating room, and slashed remuneration secondarily. As the curves flattened and healthcare infrastructure was deemed secure, we have begun opening our societies and clinical lives again. Remote care, in particular, has remained the default model of care, with attendant changes in how urological experience and education are obtained. As the colder weather looms, so does uncertainty about repeated waves of infection, the sustainability of the businesses that sustain our economy and the ability to provide high-quality, uninterrupted care outside of emergencies. To this end, we have compiled perspective and advice from previous authors and contributors to the CUA and CUAJ’s educational and research output, with a view to the future, to second waves, and ever-altered clinical landscapes.

Abstract
Urological issues in the pregnant patient present a unique clinical dilemma. These patients may be challenging to treat due to risks associated with medications and surgical procedures. This review aims to provide an update on the physiological changes and surgical risks in pregnancy. In addition, we review the approach for management of urolithiasis and urinary tract infections in pregnancy. Lastly, we highlight the importance of a multidisciplinary approach to placenta percreta, a condition not commonly addressed in urological education.

Abstract
OBJECTIVE To assess the efficacy of an herbal spray combining various essential oils, with a claim of mast cell stabilisation, antipruritic, anti-inflammatory, and insect repellent effects on the clinical presentation of insect bite hypersensitivity (IBH) in horses. DESIGN Double-blinded, placebo-controlled, randomised, cross-over clinical trial. METHODS Twenty adult horses with clinical IBH were treated with a daily application of herbal spray or placebo for 28 days in a randomised, cross-over fashion, separated by a>28-day washout period. Horses were examined and scored prior to and after the completion of each treatment. Histopathology was performed on four horses. Owners kept daily diaries of observations. RESULTS The herbal spray significantly reduced the severity of all assessed parameters (pruritus, excoriations, lichenification and alopecia; P < 0.05) compared with baseline values (pretreatment) and with placebo. Owners reported improvement of pruritus in 19/20 horses (95%) with complete resolution in 17 horses (85%) following treatment. Skin biopsies showed resolution of orthokeratosis in 4/4 horses, reduced thickness of the stratum spinosum in 2/4 horses and complete resolution of histopathological abnormalities in 1/4 horses after treatment, compared with either no change or deterioration of histopathologic lesions after placebo. No side effects were observed. CONCLUSIONS The tested herbal spray may be an effective treatment for the management of equine IBH.

Abstract
Multiple sclerosis (MS) is among the most common chronic neurological diseases, with a highly variable degree of disability during its long-term course. The majority of patients develop significant permanent disability later in life. MS is often diagnosed in women of childbearing age, with a 3:1 ratio of young women to young men with MS. Comorbidities such as depression, anxiety, migraines and reproductive, urological and bowel issues are common and negatively impact patients' quality of life. The objective of this supplement is to review the most common comorbidities occurring in young women with MS, and to propose a multidisciplinary, holistic approach to management.

High Intensity Interval Training (HIIT) Improves Cardiorespiratory Fitness (CRF) in Healthy, Overweight and Obese Adolescents: A Systematic Review and Meta-Analysis of Controlled Studies. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17082955. [PMID: 32344773 PMCID: PMC7215828 DOI: 10.3390/ijerph17082955] [Citation(s) in RCA: 47] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Revised: 04/09/2020] [Accepted: 04/17/2020] [Indexed: 12/21/2022]
Abstract
Background: High Intensity Interval Training (HIIT) is a sustainable and effective method for improving Cardiorespiratory Fitness (CRF) in adolescents. HIIT is proven to produce equal or greater improvements in CRF when compared to moderate intensity continuous exercise (MICE) in adolescents. Methods: The studies included were considered eligible if: (1) Participants were adolescents (11–18 years old); (2) Examined changes in CRF measured either directly or indirectly; (3) Included a non-exercising control group or MICE comparison group; (4) Participants were matched at enrolment; (5) Reported HIIT protocol information; (6) Provided HIIT intensity. A meta-analysis was conducted to determine the effect of HIIT on CRF. Meta-regression and moderator analyses were performed out to quantitatively examine moderators of protocol design on CRF improvements. Results: HIIT displays a moderate effect to improve CRF (g = 0.86, 95% CI 0.518–1.106, p < 0.001). Neither study duration (weeks), nor total or weekly accumulated HIIT volume (min) displayed any significant moderation effect on pooled improvement on CRF (p > 0.05). Conclusions: HIIT is an effective method to improve CRF in adolescents, irrespective of body composition. Notably, meta regression analysis identified that prolonged high volume HIIT programs are similarly effective to short term low volume HIIT programs. This becomes of particular interest for those involved in school curricula, where short HIIT exercise may provide a pragmatic adjunct to the health benefits of Physical Education (PE) lessons.

Abstract
BACKGROUND It has been reported that boys' and girls' physical activity (PA) levels decline throughout adolescence. Boys are at risk of physical inactivity during adolescence; however, in intervention research, they are an under-represented group relative to girls. It is suggested that the school environment may be central to developing interventions that support adolescents in meeting the current PA guidelines. The aim of this systematic review and meta-analysis was to investigate the efficacy of school-based physical activity interventions for improving muscular fitness (MF) in adolescent males. METHODS This systematic review and meta-analysis followed the preferred reporting systems for meta-analyses guidelines and was registered on PROSPERO (Registration number: CRD42018091023). Eligible studies were published in English within peer-reviewed articles. Searches were conducted in three databases, with an additional grey literature search in Google Scholar. Studies investigating MF outcomes were included. RESULTS There were 43 data sets identified across 11 studies, from seven countries. Overall methodological quality of the studies was moderate-to-strong. Interventions targeting MF evidenced a small-to-medium effect (g = 0.32, CI 0.17, 0.48, p < 0.00). Subgroup analyses of MF delivery method resulted in small-to-medium effects: upper limb MF measures (g = 0.28, 95% CI - 0.02, 0.58, p = 0.07), lower limb MF measures (g = 0.28, 95% CI 0.09, 0.68, p = 0.03), combined MF activities (g = 0.24, 95% CI - 0.04 to 0.49, p = 0.05), plyometric activities (g = 0.39, 95% CI 0.09, 0.68, p = 0.01), body weight (g = 0.27, 95% CI - 0.10, 0.65, p = 0.15), and traditional MF methods (g = 0.43, 95% CI 0.09, 0.78, p = 0.01). CONCLUSIONS School-based interventions which aimed to increase MF outcomes in adolescent boys demonstrated small-to-moderate effects. Traditional and plyometric methods of resistance training appear to be the most effective form of PA delivery in adolescent males. More quality research is required to assess the impact of MF delivered in the school environment to inform future intervention design.

Abstract
Purpose Long non-coding RNAs (lncRNA) are involved in oncogenesis and tumor progression in various tumor entities. At present, little is known about the role in tumor biology of the lncRNA Fer-1 like family member 4 (Fer1L4) in clear-cell renal-cell carcinoma (ccRCC). The aim of this study is to evaluate the expression of Fer1L4 in patients with ccRCC, its association with clinicopathological parameters, and value as prognostic biomarker. Material and methods The expression of Fer1L4 was analyzed in the TCGA ccRCC cohort (n = 603; ccRCC n = 522, normal n = 81) and subsequently validated by quantitative real-time PCR in an independent cohort (n = 103, ccRCC n = 69, normal n = 34). Expression profiles were statistically correlated with clinicopathological and survival data. Results Fer1L4 lncRNA is overexpressed in ccRCC compared to adjacent normal tissues. Increased expression significantly correlates with tumor aggressiveness: high expression levels of Fer1L4 RNA were found in higher grade, higher stage, and metastatic tumors. Furthermore, Fer1L4 overexpression is an independent prognostic factor for overall, cancer-specific, and progression-free survival of patients with ccRCC. Conclusion Fer1L4 expression significantly correlates with aspects of tumor aggressiveness. Based on this impact on tumor progression and its influence as an independent prognostic factor, Fer1L4 appears to exert properties as an oncogene in ccRCC. As a prognostic tissue biomarker, further functional investigations are warranted to investigate Fer1L4 as a potential therapeutic target.
