Associations between neighbourhood characteristics, physical activity and depressive symptoms: the Northern Finland Birth Cohort 1966 Study.

BACKGROUND: Due to rapid urbanization, there is a need to better understand the relative roles of residential environment and physical activity in depression. We aimed to investigate whether neighbourhood characteristics are related to the presence of depressive symptoms and whether the association is modified by physical activity. METHODS: This cross-sectional study used the 46-year-old follow-up data (n = 5489) from the Northern Finland Birth Cohort 1966. Data on depressive symptoms, measured by Beck Depression Inventory-II, and self-reported and accelerometer-measured physical activity were included. Neighbourhood characteristics, population density, distance to the closest grocery store, bus stops and cycle/pedestrian paths, distance to the nearest parks and forests, residential greenness and level of urbanicity were calculated using Geographic Information System methods based on participants' home coordinates. RESULTS: According to ordinal logistic regression analyses adjusted for physical activity at different intensities and individual covariates, living in a neighbourhood with higher population density and urbanicity level were associated with a higher risk of experiencing more severe depressive symptoms. Higher residential greenness was associated with a lower risk of experiencing more severe depressive symptoms after adjustment for self-reported light and moderate-to-vigorous physical activity, accelerometer-measured moderate-to-vigorous physical activity and individual covariates. Both higher self-reported and accelerometer-measured physical activity were independently associated with a lower risk of more severe depressive symptoms. CONCLUSIONS: Both residential environment and physical activity behaviour play an important role in depressive symptoms; however, further research among populations of different ages is required. Our findings can be utilized when designing interventions for the prevention of depression.

Nationwide analysis of survival after radical cystectomy for bladder cancer in Finland.

BACKGROUND: Population-based survival results after radical cystectomy (RC) are limited. Our objective was to report short and long-term survival results after RC for bladder cancer from Finland in a population-based setting. MATERIALS AND METHODS: The Finnish National Cystectomy Database containing retrospectively collected essential RC data covering the years 2005-2017 was combined with the survival data from the Finnish Cancer Registry. Kaplan-Meier plots were used to estimate survival and the survival graphs were illustrated according to the final pathological staging. Centers were divided according to operational volume, and the results were then compared using Pearsons's Chi-squared test. RESULTS: A total of 2047 patients were included in the study. 30-, and 90-day mortality was 1.3%, and 3.8%, respectively. The OS of the entire RC population at 5- and 10 years was 66% and 55%, and CSS was 74% and 72%, respectively. Center volume did not significantly associate with surgical mortality or long-term survival. The 5- and 10-year OS according to pT-category was 87% and 74% for pT0, 85% and 69% for pTa-pTis-pT1, 70% and 58% for pT2, 50% and 42% for pT3 and 41% and 30% for pT4. The corresponding 5- and 10-year CSS rates were 96% and 93% for pT0, 91% and 90% for pTa-pTis-pT1, 78% and 75% for pT2, 56% and 55% for pT3 and 47% and 44% for pT4. The 5- and 10-year OS rates in patients with no lymph node metastases (pN-) were 74% and 62%, and CSS 82% and 80%, respectively. If lymph nodes were positive (pN+), the corresponding OS rates were 44% and 34% and CSS 49% and 48%, respectively. CONCLUSION: RC survival results have improved in contemporary series and are associated with the pTNM-status. The nationwide results from Finland demonstrate outcome comparable to high volume single-center series.

Acknowledging geodiversity in safeguarding biodiversity and human health.

Our existence on Earth is founded on a vital nature, which supports human physical and mental health. However, nature is often depicted only through biodiversity, whereas geodiversity-the diversity of non-living nature-has so far been neglected. Geodiversity consists of assemblages, structures, and systems of geological, geomorphological, soil, and hydrological components that fundamentally underlie biodiversity. Biodiversity can support overall human health only with the foundation of geodiversity. Landscape characteristics, such as varying topography or bodies of water, promote aesthetic and sensory experiences and are also a product of geodiversity. In this Personal View, we introduce the concept of geodiversity as a driver for planetary health, describe its functions and services, and outline the intricate relationships between geodiversity, biodiversity, and human health. We also propose an agenda for acknowledging the importance of geodiversity in health-related research and decision making. Geodiversity is an emerging topic with untapped potential for ensuring ecosystem functionality and good living conditions for people in a time of changing environments.

Intraoperative complications in kidney tumor surgery: critical grading for the European Association of Urology intraoperative adverse incident classification.

INTRODUCTION: The European Association of Urology committee in 2020 suggested a new classification, intraoperative adverse incident classification (EAUiaiC), to grade intraoperative adverse events (IAE) in urology. AIMS: We applied and validated EAUiaiC, for kidney tumor surgery. PATIENTS AND METHODS: A retrospective multicenter study was conducted based on chart review. The study group comprised 749 radical nephrectomies (RN) and 531 partial nephrectomies (PN) performed in 12 hospitals in Finland during 2016-2017. All IAEs were centrally graded for EAUiaiC. The classification was adapted to kidney tumor surgery by the inclusion of global bleeding as a transfusion of ≥3 units of blood (Grade 2) or as ≥5 units (Grade 3), and also by the exclusion of preemptive conversions. RESULTS: A total of 110 IAEs were recorded in 13.8% of patients undergoing RN, and 40 IAEs in 6.4% of patients with PN. Overall, bleeding injuries in major vessels, unspecified origin and parenchymal organs accounted for 29.3, 24.0, and 16.0% of all IEAs, respectively. Bowel (n = 10) and ureter (n = 3) injuries were rare. There was no intraoperative mortality. IAEs were associated with increased tumor size, tumor extent, age, comorbidity scores, surgical approach and indication, postoperative Clavien-Dindo (CD) complications and longer stay in hospital. 48% of conversions were reactive with more CD-complications after reactive than preemptive conversion (43 vs. 25%). CONCLUSIONS: The associations between IAEs and preoperative variables and postoperative outcome indicate good construct validity for EAUiaiC. Bleeding is the most important IAE in kidney tumor surgery and the inclusion of transfusions could provide increased objectivity.

3D laparoscopic prostatectomy: results of multicentre study.

INTRODUCTION: Three-dimensional laparoscopic prostatectomy (3D LRP) is a potentially cost-effective option for robot-assisted laparoscopic prostatectomy (RALP). Results for two-dimensional LRP and RALP are well documented; however, little has been published on the outcomes of 3D LRP. Our objective was to report the perioperative and short-term results of 3D LRP in a multicentre study. MATERIALS AND METHODS: In total, 496 unselected men with prostate cancer underwent 3D LRP by three surgeons between December 2013 and December 2018. Median age was 64 (43-76) years. Median prostate-specific antigen (PSA) was 7.9 (0.7-148) ng/ml. Preoperative and perioperative data and complications according to the Clavien-Dindo classification were collected. PSA and continence results were reported at 3 and 12 months postoperatively. Data were analysed with IBM SPSS statistics (25). RESULTS: Pathological Gleason score was 6 in 29%, 7 in 55.4%, 8 in 9.1%, 9 in 5.2% and 10 in 1.2% of patients. Pathological tumour classification was T2c in 59.5%, T3a in 19.5% and T3b in 10.9% of cases. Positive surgical margins occurred in 27.2%. Lymphadenectomy was performed in 36.3%, with positive lymph nodes in 11.8%. Median operative time was 137 (78-334) min and median blood loss 200 (10-1100) ml. Clavien-Dindo IIIa and IIIb complications occurred in 6.9% and 1.6%, respectively. At 3 and 12 months postoperatively, 90.2% and 91.4% of patients, respectively, had PSA <0.2 ng/ml, while 77.1% and 87.7% of patients were completely dry or using a maximum of one pad daily. CONCLUSIONS: 3D LRP shows promising results, comparable to similar studies published on RALP.

Individualised non-contrast MRI-based risk estimation and shared decision-making in men with a suspicion of prostate cancer: protocol for multicentre randomised controlled trial (multi-IMPROD V.2.0).

INTRODUCTION: European Association of Urology and UK National Institute for Health and Care Excellence guidelines recommend that all men with suspicions of prostate cancer should undergo prebiopsy contrast enhanced, that is, multiparametric prostate MRI. Subsequent prostate biopsies should also be performed if MRI is positive, that is, Prostate Imaging-Reporting and Data System (PI-RADS) scores 3-5. However, several retrospective post hoc analyses have shown that this approach still leads to many unnecessary biopsy procedures. For example, 88%-96% of men with PI-RADS, three findings are still diagnosed with clinically non-significant prostate cancer or no cancer at all. METHODS AND ANALYSIS: This is a prospective, randomised, controlled, multicentre trial, being conducted in Finland, to demonstrate non-inferiority in clinically significant cancer detection rates among men undergoing prostate biopsies post-MRI and men undergoing prostate biopsies post-MRI only after a shared decision based on individualised risk estimation. Men without previous diagnosis of prostate cancer and with abnormal digital rectal examination findings and/or prostate-specific antigen between 2.5 ug/L and 20.0 ug/L are included. We aim to recruit 830 men who are randomised at a 1:1 ratio into control (all undergo biopsies after MRI) and intervention arms (the decision to perform biopsies is based on risk estimation and shared decision-making). The primary outcome of the study is the proportion of men with clinically significant prostate cancer (Gleason 4+3 prostate cancer or higher). We will also compare the overall biopsy rate, benign biopsy rate and the detection of non-significant prostate cancer between the two study groups. ETHICS AND DISSEMINATION: The study (protocol V.2.0, 4 January 2021) was approved by the Ethics Committee of the Hospital District of Southwest Finland (IORG number: 0001744, IBR number: 00002216; trial number: 99/1801/2019). Participants are required to provide written informed consent. Full reports of this study will be submitted to peer-reviewed journals, mainly urology and radiology. TRIAL REGISTRATION NUMBER: NCT04287088; the study is registered at ClinicalTrials.gov.

Cross-cultural comparison of depressive symptoms on the Beck Depression Inventory-II, across six population samples.

BACKGROUND: The Beck Depression Inventory (BDI) and BDI-II (revised version) are some of the most widely used and comparable self-report scales for assessing the presence and severity of depressive symptoms in many countries. However, although the relative mean score of each symptom in different countries may vary, the cultural differences of BDI-II symptoms for each item have not been previously studied. AIMS: To examine the overall picture of the magnitude of the symptoms in the Finnish population, and compare the relative mean score of each symptom between all published population-based samples from different countries fulfilling the search criteria. METHOD: We conducted a search for population-based studies reporting BDI-II item, using Scopus, PsycINFO and PubMed, and five population-based samples were identified. Relative average scores for each item of the scale were calculated for the Finnish population and five populations from other countries. Meta-regression methods were used to test the differences in the relative score of each symptom between each country separately, and results were then visually compared with spider charts. RESULTS: We found significant differences in several BDI-II item scores between countries: lower indecisiveness, higher changes in sleep pattern and higher irritability in Finland; higher loss of pleasure in Norway; higher loss of interest in the Dominic Republic; higher self-criticalness and feelings of punishment in Mexico; and higher sadness in Japan. CONCLUSIONS: Based on the study fundings and including all currently published population-based samples with BDI-II scores, cultural differences in depressive symptoms should be considered when interpreting BDI-II item scores.

Awareness of Smoking as a Risk Factor in Bladder Cancer: Results from the Prospective FinnBladder 9 Trial.

BACKGROUND: Data regarding patient education and smoking habits among bladder cancer patients are scarce. OBJECTIVE: To investigate awareness of smoking as a risk factor for bladder cancer among bladder cancer patients. DESIGN, SETTING, AND PARTICIPANTS: This is a substudy of a prospective, randomized, multicenter phase 3 trial (FinnBladder 9, NCT01675219). The data were collected at baseline and after 12 mo of follow-up between 2012 and 2020. INTERVENTION: Patients completed a comprehensive nonvalidated questionnaire on smoking in relation to bladder cancer. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The outcomes measured were patient-reported awareness of smoking as a risk factor for bladder cancer, and the effect of smoking on bladder cancer-related recurrence, progression, and death. Parametric data were compared using Student's t test and proportions using Fischer's exact test. Factors affecting baseline awareness of the effect of smoking cessation on bladder cancer were studied using logistic regression. RESULTS AND LIMITATIONS: Of the 411 patients randomized, 370 completed the baseline questionnaire and were included in the analysis. At baseline, 44% of patients were uncertain if smoking was a risk factor for bladder cancer. Patient awareness of the fact that smoking cessation reduces the risk of bladder cancer recurrence increased from 86% to 92% after 12 mo of follow-up (p = 0.038). Older patients and patients with recurrent bladder cancer had significantly less knowledge about the effect of smoking on bladder cancer recurrence, progression, and mortality. A major limitation is that the response rate was lower at the 12-mo follow-up visit than at baseline. CONCLUSIONS: Awareness of smoking as a bladder cancer risk factor is low. Older patients and patients with recurrent bladder cancer may need special attention regarding education. PATIENT SUMMARY: We looked at outcomes for smoking-related patient education on bladder cancer in a Finnish population. We conclude that older patients and patients with recurrent bladder cancer may need to be educated on this subject.

Detection of Prostate Cancer Using Biparametric Prostate MRI, Radiomics, and Kallikreins: A Retrospective Multicenter Study of Men With a Clinical Suspicion of Prostate Cancer.

BACKGROUND: Accurate detection of clinically significant prostate cancer (csPCa), Gleason Grade Group ≥ 2, remains a challenge. Prostate MRI radiomics and blood kallikreins have been proposed as tools to improve the performance of biparametric MRI (bpMRI). PURPOSE: To develop and validate radiomics and kallikrein models for the detection of csPCa. STUDY TYPE: Retrospective. POPULATION: A total of 543 men with a clinical suspicion of csPCa, 411 (76%, 411/543) had kallikreins available and 360 (88%, 360/411) did not take 5-alpha-reductase inhibitors. Two data splits into training, validation (split 1: single center, n = 72; split 2: random 50% of pooled datasets from all four centers), and testing (split 1: 4 centers, n = 288; split 2: remaining 50%) were evaluated. FIELD STRENGTH/SEQUENCE: A 3 T/1.5 T, TSE T2-weighted imaging, 3x SE DWI. ASSESSMENT: In total, 20,363 radiomic features calculated from manually delineated whole gland (WG) and bpMRI suspicion lesion masks were evaluated in addition to clinical parameters, prostate-specific antigen, four kallikreins, MRI-based qualitative (PI-RADSv2.1/IMPROD bpMRI Likert) scores. STATISTICAL TESTS: For the detection of csPCa, area under receiver operating curve (AUC) was calculated using the DeLong's method. A multivariate analysis was conducted to determine the predictive power of combining variables. The values of P-value < 0.05 were considered significant. RESULTS: The highest prediction performance was achieved by IMPROD bpMRI Likert and PI-RADSv2.1 score with AUC = 0.85 and 0.85 in split 1, 0.85 and 0.83 in split 2, respectively. bpMRI WG and/or kallikreins demonstrated AUCs ranging from 0.62 to 0.73 in split 1 and from 0.68 to 0.76 in split 2. AUC of bpMRI lesion-derived radiomics model was not statistically different to IMPROD bpMRI Likert score (split 1: AUC = 0.83, P-value = 0.306; split 2: AUC = 0.83, P-value = 0.488). DATA CONCLUSION: The use of radiomics and kallikreins failed to outperform PI-RADSv2.1/IMPROD bpMRI Likert and their combination did not lead to further performance gains. LEVEL OF EVIDENCE: 1 TECHNICAL EFFICACY: Stage 2.

Regional Variation in Restorative Treatment Need among Finnish Young People.

AIM: To evaluate the regional variation in restorative treatment need among Finnish young people based on the socioeconomic factors. MATERIALS AND METHODS: This cross-sectional study was conducted in 20 garrisons of the Finnish Defence Forces in January and July 2011. The study population comprised 13,819 Finnish conscripts born in the beginning of 1990s, including females. A computer-based survey was done together with clinical oral examination to gather background information, e.g., educational status. Furthermore, average annual income of the conscript's residence municipality was achieved from the Statistics of Finland. The zip code of the place of residence of each conscript was later extracted from the Mildoc® system. Georeferenced place of residence and income status were merged as information on provinces' level in a dataset. The association between the outcome variable and explanatory variables was determined by using the generalized linear mixed model, and geomaps were constructed. RESULTS: Mean D value was 1.41 ranging from 0.89 (Kymenlaakso) to 2.33 (Kainuu). Higher education and high-income level were protective factors for restorative treatment need. Restorative treatment need was also low in those areas with high (OR: 0.70, 95% CI: 0.56-0.87) and medium (OR: 0.79, 95% CI: 0.70-0.89) yearly income compared to low yearly income. The high odds for the need of restorative treatment were discovered in Northern Ostrobothnia (OR: 2.26, 95% CI: 1.53-3.33) followed by Central Ostrobothnia (OR: 2.08, 95% CI: 1.17-3.70), Uusimaa (OR: 1.55, 95% CI: 1.16-2.08), and Central Finland (OR: 1.54, 95% CI: 1.10-2.16) compared to Varsinais-Suomi. CONCLUSION: In conclusion, there is a significant regional variation in restorative treatment need among Finnish young people in their twenties based on the socioeconomic factors.

Does every Clavien-Dindo complication matter? A national multi-center study in kidney cancer surgery.

BACKGROUND: There is huge variation in Clavien-Dindo (CD) complication rates in urology. We sought to optimize the use of the CD system in kidney tumor surgery. METHODS: We retrospectively analyzed 1,286 patients undergoing kidney tumor operations in 12 Finnish hospitals during 2016-2017. Primary CD assignments were made by site urologists. Data were centrally reviewed by two authors in consensus meetings. Consistency of the primary assignments was assessed by the number of cases requiring correction. Complication load was compared as different outcome rates between five university hospital regions. RESULTS: The overall complication rate in primary data was 40% (517/1286) and varied significantly from 32 to 62% (p < 0.001) between the regions. The need for corrections in central review was significantly greater for CD1 (54%) compared to CD2 (16%, p < 0.001) and CD3-5 (11%, p < 0.001) categories. The final data comprised 500 CD complications after 390 surgeries. The most frequent pathologies were bleeding (8.4%), urological complications (5.9%) and postoperative fever (4.7%). The overall CD2 complications rate was statistically (p < 0.001) higher in region D and that of CD3-5 was higher (p = 0.007) in region B. In multivariable analysis, university hospital region, male sex, BMI ≥ 27, ECOG ≥ 1, partial nephrectomy type and open surgery significantly increased the risk of complications. CONCLUSIONS: Comparative use of CD1 complications may be too inconsistent and only CD2-5 complications should be reported. Central review of the primary data and detailed guidelines are necessary.

Repetitive Transcranial Magnetic Stimulation for Chronic Prostatitis/Chronic Pelvic Pain Syndrome: A Prospective Pilot Study.

PURPOSE: To evaluate the feasibility, efficacy, and safety of repetitive transcranial magnetic stimulation (rTMS) in patients with treatment-resistant chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS: Eleven patients with CP/CPPS were enrolled in this prospective clinical study. rTMS was performed for 5 consecutive days in 20-minute sessions. Patients were evaluated at baseline, after treatment, and at 1, 4, 8, and 12 weeks after the last session with questionnaires concerning pain (numerical rating scale [NRS], the National Institutes of Health Chronic Prostatitis Symptom Index [NIH-CPSI], and the Short Form-36 [SF-36]), urinary symptoms (NIH-CPSI, Danish Prostatic Symptom Score [DAN-PSS-1]), quality of life (NIH-CPSI, SF-36), and psychometrics (Beck Depression Index [BDI]). Telephone-based interviews were used to evaluate side effects, subjective response, and changes in drug consumption. RESULTS: All patients completed the planned treatment and follow-up according to protocol. No patients experienced serious side effects or significant pain increase during or after treatment. Mild transient tension headache responsive to oral pain medication was reported by 2 patients. Decreased pain was observed on the NRS after treatment and at 1 and 8 weeks (P=0.019, P=0.006, P=0.042, respectively) and on the NIH-CPSI pain domain at 1 week (P=0.04). Improvement in lower urinary tract symptoms was observed after treatment in the NIH-CPSI urinary domain (P=0.02) but not with the DANPSS-1. No significant changes in the BDI were observed. Nine patients reported a positive overall subjective response (82%) and 6 patients (55%) were able to reduce pain medication. Higher age was associated with lower NRS scores after treatment (R=0.605, P=0.048) and at 8 weeks (R=0.659, P=0.028). CONCLUSION: rTMS for patients with CP/CPPS seemed to be well tolerated, at least moderately effective in pain reduction, and might be of interest in patients with chronic pelvic pain resistant to conventional treatment. These findings remain to be confirmed by a randomized trial.

Symptoms and diagnostic delays in bladder cancer with high risk of recurrence: results from a prospective FinnBladder 9 trial.

PURPOSE: To investigate the symptoms and delays in the clinical pathway of bladder cancer (BC). METHODS: This is a substudy of a prospective, randomized, multicenter phase III study (FinnBladder 9, NCT01675219) where the efficacy of photodynamic diagnosis and 6 weekly optimized mitomycin C instillations are studied in pTa bladder cancer with high risk for recurrence. The data of presenting symptoms and critical time points were prospectively collected, and the effect of factors on delays was analyzed. RESULTS: At the time of analysis, 245 patients were randomized. Analysis included 131 patients with primary bladder cancer and their complete data. Sixty-nine percent had smoking history and 67% presented with macroscopic hematuria. Median patient delay (from symptoms to health-care contact) was 7 days. The median general practice delay (from health-care contact to urology referral) was 8 days. Median time from urology referral to cystoscopy was 23 days and from cystoscopy to TUR-BT 21 days. Total time used in the clinical pathway (from symptom to TUR-BT) was 78 days. Current and former smokers had non-significantly shorter patient-related and general practice delays compared to never smokers. TUR-BT delay was significantly shorter in patients with malignant cytology (16 days) compared to patients with benign cytology (21 days, p = 0.03). CONCLUSIONS: Patient-derived delay was short and most of the delay occurred in the referral centers. The majority had macroscopic hematuria as the initial symptom. Surprisingly, current and past smokers were more prone to contact the health-care system compared to never smokers.

Qualitative and Quantitative Reporting of a Unique Biparametric MRI: Towards Biparametric MRI-Based Nomograms for Prediction of Prostate Biopsy Outcome in Men With a Clinical Suspicion of Prostate Cancer (IMPROD and MULTI-IMPROD Trials).

BACKGROUND: Multiparametric MRI of the prostate has been shown to improve the risk stratification of men with an elevated prostate-specific antigen (PSA). However, long acquisition time, high cost, and inter-center/reader variability of a routine prostate multiparametric MRI limit its wider adoption. PURPOSE: To develop and validate nomograms based on unique rapid biparametric MRI (bpMRI) qualitative and quantitative derived variables for prediction of clinically significant cancer (SPCa). STUDY TYPE: Retrospective analyses of single (IMPROD, NCT01864135) and multiinstitution trials (MULTI-IMPROD, NCT02241122). POPULATION: 161 and 338 prospectively enrolled men who completed the IMPROD and MULTI-IMPROD trials, respectively. FIELD STRENGTH/SEQUENCE: IMPROD bpMRI: 3T/1.5T, T2 -weighted imaging, three separate diffusion-weighted imaging (DWI) acquisitions: 1) b-values 0, 100, 200, 300, 500 s/mm2 ; 2) b values 0, 1500 s/mm2 ; 3) values 0, 2000 s/mm2 . ASSESSMENT: The primary endpoint of the combined trial analysis was the diagnostic accuracy of the combination of IMPROD bpMRI and clinical variables for detection of SPCa. STATISTICAL TESTS: Logistic regression models were developed using IMPROD trial data and validated using MULTI-IMPROD trial data. The model's performance was expressed as the area under the curve (AUC) values for the detection of SPCa, defined as ISUP Gleason Grade Group ≥2. RESULTS: A model incorporating clinical variables had an AUC (95% confidence interval) of 0.83 (0.77-0.89) and 0.80 (0.75-0.85) in the development and validation cohorts, respectively. The corresponding values for a model using IMPROD bpMRI findings were 0.93 (0.89-0.97), and 0.88 (0.84-0.92), respectively. Further addition of the quantitative DWI-based score did not improve AUC values (P < 0.05). DATA CONCLUSION: A prediction model using qualitative IMPROD bpMRI findings demonstrated high accuracy for predicting SPCa in men with an elevated PSA.

Validation of IMPROD biparametric MRI in men with clinically suspected prostate cancer: A prospective multi-institutional trial.

BACKGROUND: Magnetic resonance imaging (MRI) combined with targeted biopsy (TB) is increasingly used in men with clinically suspected prostate cancer (PCa), but the long acquisition times, high costs, and inter-center/reader variability of routine multiparametric prostate MRI limit its wider adoption. METHODS AND FINDINGS: The aim was to validate a previously developed unique MRI acquisition and reporting protocol, IMPROD biparametric MRI (bpMRI) (NCT01864135), in men with a clinical suspicion of PCa in a multi-institutional trial (NCT02241122). IMPROD bpMRI has average acquisition time of 15 minutes (no endorectal coil, no intravenous contrast use) and consists of T2-weighted imaging and 3 separate diffusion-weighed imaging acquisitions. Between February 1, 2015, and March 31, 2017, 364 men with a clinical suspicion of PCa were enrolled at 4 institutions in Finland. Men with an equivocal to high suspicion (IMPROD bpMRI Likert score 3-5) of PCa had 2 TBs of up to 2 lesions followed by a systematic biopsy (SB). Men with a low to very low suspicion (IMPROD bpMRI Likert score 1-2) had only SB. All data and protocols are freely available. The primary outcome of the trial was diagnostic accuracy-including overall accuracy, sensitivity, specificity, negative predictive value (NPV), and positive predictive value-of IMPROD bpMRI for clinically significant PCa (SPCa), which was defined as a Gleason score ≥ 3 + 4 (Gleason grade group 2 or higher). In total, 338 (338/364, 93%) prospectively enrolled men completed the trial. The accuracy and NPV of IMPROD bpMRI for SPCa were 70% (113/161) and 95% (71/75) (95% CI 87%-98%), respectively. Restricting the biopsy to men with equivocal to highly suspicious IMPROD bpMRI findings would have resulted in a 22% (75/338) reduction in the number of men undergoing biopsy while missing 4 (3%, 4/146) men with SPCa. The main limitation is uncertainty about the true PCa prevalence in the study cohort, since some of the men may have PCa despite having negative biopsy findings. CONCLUSIONS: IMPROD bpMRI demonstrated a high NPV for SPCa in men with a clinical suspicion of PCa in this prospective multi-institutional clinical trial. TRIAL REGISTRATION: ClinicalTrials.gov NCT02241122.

Prevalence of Complications Leading to a Health Care Contact After Transrectal Prostate Biopsies: A Prospective, Controlled, Multicenter Study Based on a Selected Study Cohort.

BACKGROUND: Transrectal ultrasound-guided prostate biopsy (TRUS-Bx) is typically considered a safe procedure. However, infectious complications have been increasing. OBJECTIVE: To determine the contemporary rate of biopsy-related infectious and noninfectious complications after TRUS-Bx, and identify potential risk factors associated with the complications. DESIGN, SETTING, AND PARTICIPANTS: This was a prospective multicenter study and a substudy of a trial investigating the role of magnetic resonance imaging (MRI) in prostate cancer diagnosis (multi-IMPROD, NCT02241122). INTERVENTION: TRUS-Bx was performed for all patients included in the study. Ciprofloxacin, levofloxacin, or fosfomycin was administered for antibiotic prophylaxis. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: On inclusion, patients completed a detailed questionnaire and underwent MRI scanning. Antibiotic prophylaxis was prospectively recorded. After collection of a rectal swab, TRUS-Bx (total of 14-18 biopsy cores) was performed and. The rectal swabs were cultured and the antimicrobial susceptibility profile of Escherichia coli strains was analyzed. Biopsy complications leading to a visit to a health care unit were recorded and potential risk factors for complications were analyzed. RESULTS AND LIMITATIONS: Twelve of the 294 patients (4.1%) had a biopsy-related complication, of which two (0.7%) were infectious and managed in the outpatient setting. Some 11% of the patients had an E. coli strain resistant to the prophylactic antibiotic administered. CONCLUSIONS: The risk of an infectious or noninfectious complication after TRUS-Bx is very low, although the FQ resistance rate in the study population was significant. Accordingly, the present TRUS-Bx procedure and antibiotic prophylaxis are efficient in guarding against biopsy complications, but regional resistance rates may affect the generalizability of the results. PATIENT SUMMARY: We examined the rate of complications after prostate biopsies in 294 patients. The risk of having a biopsy-related complication was low (4.1%). The rate of infectious complications was reasonably low (0.7%) although antibiotic resistance to the prophylactic antibiotic regimen was significant (11%).

Urine cytology is a feasible tool for assessing erythematous bladder lesions after bacille Calmette-Guérin (BCG) treatment.

OBJECTIVES: To investigate the need to biopsy erythematous lesions of the bladder after bacille Calmette-Guérin (BCG) treatment as well as the diagnostic value of voided urine cytology in the detection of recurrence. MATERIALS AND METHODS: Data on 206 consecutive patients with non-muscle-invasive bladder cancer treated with one or more BCG instillations in the period 2009-2015 at Satakunta Central Hospital and Turku University Hospital were reviewed. Biopsy histology was pooled according to lesion cystoscopy appearance regarding growth pattern and presence of erythema. Voided urine cytology grading before resection was reviewed. We correlated the cystoscopy findings with histology and calculated the sensitivity, specificity, and positive (PPV) and negative predictive value (NPV) for voided urine cytology. RESULTS: In total, 159 patients with a median follow-up of 35 months were included in the study. Altogether, 367 biopsies were analysed. In the case of papillary or flat tumours, 76% of biopsies showed malignant histology and the diagnostic value of cytology was very limited (sensitivity 33%, specificity 84%). Erythematous lesions constituted 57% of all biopsy targets, with the majority being either chronic non-specific inflammation or granulomatous inflammation; 10% of erythematous lesions were malignant at pathological examination. In contrast to papillary and flat tumours, cytology proved to be more accurate in the case of erythematous lesions with a sensitivity, specificity, PPV and NPV of 59%, 76%, 23% and 94%, respectively. CONCLUSION: Bladder lesions after BCG instillations pose a challenge during follow-up and the appropriate management strategy is not clear. Lesions should not be overlooked as being BCG-induced irritation because they may harbour significant malignancies. The presence of papillary or flat tumour always warrants a biopsy or resection. In the case of erythematous lesions, our results suggest that biopsy may be avoided if voided urine cytology is negative.

Oral health status associated with sociodemographic factors of Nepalese schoolchildren: a population-based study.

OBJECTIVES: The aim of this study was to investigate the oral health of Nepalese schoolchildren relative to their sociodemographic characteristics. METHODS: This school-based, cross-sectional study was conducted among 5-6-, 12- and 15-year-old Nepalese children in 18 randomly selected districts of the 75 in Nepal. Clinical parameters were recorded according to the World Health Organization (WHO) guidelines. Results were presented as mean (SD) and proportions; the chi-square test, t-test and one way-ANOVA were also performed. The risk of dental caries in association with the place of residence was presented according to the outcome of a binary logistic regression analysis. RESULTS: The mean d-value for the 5-6-year-old children was 5.0 (4.22), which was higher than the mean D-values for the 12- and 15-year-old subjects, of 1.3 (1.77) and 1.9 (2.28), respectively. The youngest children, as well as children from the Kathmandu Valley, were likely to have more untreated caries lesions than children in the other age groups. The mean number of teeth with severe consequences of dental caries (pulpitis/ulceration/fistula/abscess or pufa/PUFA) was 1.3 (1.91) for the 5-6-year-old children, 0.1 (0.35) for the 12-year-old children and 0.3 (0.75) for the 15-year-old children. All age groups had gingival bleeding on probing in more than 15% of teeth. Children from rural locations had significantly more gingival bleeding than urban children. The same was true for 15-year-old girls compared with boys of the same age. CONCLUSIONS: Among Nepalese children, oral diseases are common, and geographical variation is prevalent. The health policy should address the alarming oral health situation and need for urgent treatment and population-based preventive programmes that is evident in Nepal.

Antibiotic susceptibility of intestinal Escherichia coli in men undergoing transrectal prostate biopsies: a prospective, registered, multicentre study.

OBJECTIVES: To determine, in a prospective, multicentre setting, the prevalence of fluoroquinolone-resistant (FQ-R) and extended-spectrum ß-lactamase (ESBL)-producing Escherichia coli (E. coli) strains in men undergoing transrectal ultrasonography-guided prostate biopsy (TRUS-Bx) in Finland; and to survey the associated risk factors for having the previously mentioned strains. PATIENTS AND METHODS: This is a substudy of the trial investigating the role of magnetic resonance imaging (MRI) in prostate cancer diagnosis (Improved Prostate Cancer Diagnosis - Combination of Magnetic Resonance Imaging Targeted Biopsies and Biomarkers Multi-institutional Study [multi-IMPROD], NCT02241122). In all, 359 patients from four study centres were recruited to this prospective study. After having signed the informed consent form, these men with suspicion of prostate cancer completed a detailed questionnaire on their medical, smoking, and travelling history, as well as their recent use of antibiotics. After the bi-parametric MRI scan, TRUS-Bx was taken and a rectal swab sample was collected and cultured for determining the antimicrobial susceptibility profile of E. coli strains. The potential risk factors for having FQ-R or third-generation cephalosporin-resistant (3GC-R) E. coli strains were analysed using univariate and multivariate logistic regression analysis. RESULTS: The percentage of FQ-R and 3GC-R E. coli strains amongst the study population was 13% and 8%, respectively. Amongst patients having E. coli strains, the rate of FQ-R and 3GC-R strains was 14% and 8%, respectively. Of the 3GC-R E. coli strains, 62% proved to be ESBL-producers and 88% were also FQ-R. In multivariate analysis, international travel during the preceding year significantly increased the risk of having a FQ-R E. coli strain (odds ratio [OR] 3.592, P = 0.001) and, unexpectedly, use of antibiotics during the previous year significantly decreased this risk (OR 0.442, P = 0.035). No significant risk factors for having 3GC-R E. coli were identified. CONCLUSION: The occurrence of intestinal FQ-R and/or 3GC-R (potentially ESBL-producing) E. coli strains in men undergoing TRUS-Bx in Finland is notable. The finding is consistent with the global increase in antimicrobial resistance. International travel appears to be an indisputable risk factor for having intestinal FQ-R E. coli strains. The contemporary antimicrobial resistance situation should be taken into account in the care of post-TRUS-Bx infections.
