RESUMEN
PURPOSE: The prognosis of upper urinary tract urothelial carcinoma (UTUC) is associated with tumour grade (G) and stage. Despite preoperative risk stratification and radical treatment, recurrence and progression are common. Thus, prognostic and monitoring biomarkers are needed. This feasibility study aimed to investigate if targeted analyses on circulating tumour DNA (ctDNA) in plasma could identify tumour-specific gene variants, and thus have potential for further evaluation as a biomarker in UTUC. METHODS: Nine UTUC patients with genetically characterised tumours were included in this prospective pilot study. Two tumour-specific variants were chosen for targeted analyses with multiplex droplet digital PCR on cell-free DNA (cfDNA) from plasma at diagnosis or from recurrence. RESULTS: Of six patients with diagnostic plasma samples, ctDNA was detected in four with G2 or G3 tumours and tumours > 300m2 in size. Three of these patients progressed in their disease and the fourth had the largest G3 tumour at sampling. In contrast, the two patients with undetectable ctDNA in diagnostic plasma had a G1 tumour and G3 carcinoma in situ (CIS), respectively. The patient with G3 CIS had detectable ctDNA later during follow-up and progressed thereafter with aggressive intravesical recurrence and CT-scan-verified CIS progression in the upper urinary tract. In three patients with small recurrent G1 or G2 tumours, none had detectable ctDNA in plasma and all were progression free. CONCLUSION: Our early findings demonstrate that ctDNA in plasma can be detected by targeted analysis in patients with UTUC. However, further studies are needed to determine its role as a potential biomarker.

PURPOSE: To summarise the current knowledge regarding diagnostics, prognostication and follow-up in upper tract urothelial carcinoma (UTUC). METHODS: A scoping review combined with expert opinion was applied to provide an overview of the current research field. Based on the published literature and the experts' own experience and opinions, consensus was reached through presentations and discussions at the meeting Consultation on UTUC II in Stockholm 2022. RESULTS: The strongest prognostic factors in UTUC are tumour grade and stage. They are correlated, and grade is used for indirect staging. The diagnostic examinations should include multiphase computed tomography urography (CTU) with corticomedullary phase, and urethrocystoscopy with cytology. If there is no clear diagnosis for clinical decision-making, ureterorenoscopy (URS) with focal cytology and biopsies should be performed. Both WHO classification systems (1973/1999 and 2004/2016) should be used. Novel biomarker tests are not yet widespread nor recommended for the detection of UTUC. Long-term, regular follow-up, including URS in patients who have had organ-sparing treatment, is important to check for tumour recurrences, intravesical recurrences, metastases and progression of the tumour. CONCLUSION: Proper diagnostics with correct grading of UTUC are necessary for appropriate treatment decisions. The diagnostics should include CTU with corticomedullary phase, urine or bladder cytology, URS with focal barbotage cytology, and biopsies when needed for proper diagnosis and risk stratification. Regular, long-term follow-ups are fundamental, due to the high rate of recurrence and risk of progression.

AIM: Patient-reported pad-count as continence rate assessment tool after artificial urinary sphincter (AUS) implantation is common. However, lack of standardized continence definition using this method results in heterogeneous published efficacy outcomes. Data on 24-h pad weight tests (PWT) after primary AUS implantation for postprostatectomy urinary incontinence (PPUI) is scarce. Our aim was to evaluate the 24-h PWT as an efficacy assessment tool and correlate it to qualitative outcomes using validated questionnaires. METHODS: This retrospective, single center, follow-up cohort study, evaluated 180 patients who underwent primary AUS implantation for PPUI from 2005 to 2018. Voiding diaries, 24-h PWT, validated patient satisfaction and quality of life (QoL) questionnaires were collected pre-operatively and at 3-6 months postactivation, using the institution's Electronic Medical Records. RESULTS: The median preoperative and postoperative 24-h PWT values were 494 (interquartile range [IQR]: 304-780) and 7 (IQR: 0-25) g respectively with a significant improvement in urinary leakage of 489.5 g 99.1% (p < 0.001). Median preoperative and postoperative I-QoL results increased from 33.5 (IQR: 19.3-63.6) to 86.4 (IQR: 73.9-94.3) points, with a significant 52.9 points improvement in QoL (p < 0.001). Similarly, the median preoperative and postoperative ICIQ-SF values decreased from 20 (IQR: 17-21) to 5 (IQR: 3-9) points, showing a significant improvement of 15 points (p < 0.001). We also found a significant correlation between PWT and patient satisfaction. CONCLUSION: The 24-h PWT provides a reliable and objective assessment of continence rates, with a strong correlation to qualitative outcomes, after primary AUS implantation for PPUI. Its use could help reduce reported outcome heterogeneity across studies.

INTRODUCTION: Although abortion care has been an established routine since decades in India, 8% of maternal mortality is attributed to unsafe abortion. Increased knowledge and improved attitudes among health care providers have a potential to reduce barriers to safe abortion care by reducing stigma and reluctance to provide abortion. Previous research has shown that medical students' attitudes can predict whether they will perform abortions. The objective of our study was to explore attitudes toward abortion among medical interns in Maharastra, India. STUDY DESIGN: A cross-sectional survey was carried out among 1996 medical interns in Maharastra, India. Descriptive and analytical statistics were used to interpret the study instrument. RESULTS: Almost one quarter of the respondents considered abortion to be morally wrong, one fifth did not find abortions for unmarried women acceptable and one quarter falsely believed that a woman needs her partner or spouse's approval to have an abortion. Most participants agreed that unsafe abortion is a serious health problem in India. A majority of the respondents rated their knowledge of sexual and reproductive health as good, but only 13% had any clinical practice in abortion care services. CONCLUSION: Disallowing attitudes toward abortion and misconceptions about the legal regulations were common among the surveyed medical students. Knowledge and attitudes toward abortion among future physicians could be improved by amendments to the medical education, potentially increasing the number of future providers delivering safe and legal abortion services. IMPLICATION PARAGRAPH: Abortion is legal in India since decades, but maternal mortality due to unsafe abortions remains high. This survey of attitudes toward abortion among medical interns in Maharastra indicates that disallowing views prevail. Improved knowledge and clinical training can increase numbers of potential abortion providers, thus limit unsafe abortion.
