RESUMO

Despite the progress of anti-cancer treatment, the prognosis of many patients with solid tumors is still dismal. Reliable noninvasive biomarkers are needed to predict patient survival and therapy response. Here, we propose a Humoral Complementomics approach: a work-up of assays to comprehensively evaluate complement proteins, activation fragments, and autoantibodies targeting complement proteins in plasma, which we correlated with the intratumoral complement activation, and/or local production, focusing on localized and metastatic clear cell renal cell carcinoma (ccRCC). In two prospective ccRCC cohorts, plasma C2, C5, Factor D and properdin were elevated compared to healthy controls, reflecting an inflammatory phenotype that correlated with plasma calprotectin levels but did not associate with CRP or with patient prognosis. Conversely, autoantibodies against the complement C3 and the reduced form of FH (a tumor neo-epitope reported in lung cancer) correlated with a favorable outcome. Our findings pointed to a specific group of patients with elevated plasma C4d and C1s-C1INH complexes, indicating the initiation of the classical pathway, along with elevated Ba and Bb, indicating alternative pathway activation. Boostrapped Lasso regularized Cox regression revealed that the most predictive complement biomarkers were elevated plasma C4d and Bb levels at the time of surgery, which correlated with poor prognosis. In conclusion, we propose Humoral Complementomics as an unbiased approach to study the global state of the complement system in any pathological plasma sample and disease context. Its implementation for ccRCC revealed that elevated C4d and Bb in plasma are promising prognostic biomarkers, correlating with shorter progression-free survival.

RESUMO

OBJECTIVE: To present the patient-reported quality of life (QoL) outcomes from a prospective, randomized controlled trial comparing the use of pelvic floor muscle training (PFMT) and duloxetine after robot-assisted radical prostatectomy (RARP). METHODS: We identified 213 men with organ-confined disease having post-RARP urinary incontinence who were randomly assigned to received PFMT, duloxetine, combined PFMT-duloxetine and pelvic floor muscle home exercises. Urinary symptoms burden was measured by marked clinical important difference improvement (MCID) defined by using the International Prostate Symptom Score (IPSS) difference of - 8 points (ΔIPSS ≤-8). QoL was assessed according to Visual Analog Scale (VAS), King's Health Questionnaire (KQH), and International Index of Erectile Function (IIEF-5). Multivariable regression analyses aimed to predict MCID, burden of urinary symptoms (IPSS ≥8), and patients reporting to be satisfied (IPSS QoL ≤2) or comfortable (VAS ≤1) post-RARP. RESULTS: Moderate to severe urinary symptoms decreased from 48% preoperatively to 40%, 34%, and 23% at 3, 6, and 12months post-RARP. After surgery, MCID improvement was observed in 19% of patients, and deterioration in 3.3%. Large prostate was the only factor associated to MCID (OR 1.03 [95%CI 1.01-1.05], P = .005). At 6months, patients reached the same degree of preoperative satisfaction. Neurovascular bundle preservation was the only predictor of being comfortable regarding urinary symptoms postoperatively (OR 12.8 [CI95% 1.47-111.7], P = .02 at 3months) and was also associated to higher median postoperative IIEF-5. CONCLUSION: Despite urinary incontinence following RARP, patients with larger prostates experience a reduction of lower urinary tract symptoms within a year, which subsequently elevates QoL. Furthermore, nerve-sparing surgery augments erectile function and urinary outcomes, shaping postoperative QoL.

RESUMO

PURPOSE: Accurate prediction of extraprostatic extension (EPE) is pivotal for surgical planning. Herein, we aimed to provide an updated model for predicting EPE among patients diagnosed with MRI-targeted biopsy. MATERIALS AND METHODS: We analyzed a multi-institutional dataset of men with clinically localized prostate cancer diagnosed by MRI-targeted biopsy and subsequently underwent prostatectomy. To develop a side-specific predictive model, we considered the prostatic lobes separately. A multivariable logistic regression analysis was fitted to predict side-specific EPE. The decision curve analysis was used to evaluate the net clinical benefit. Finally, a regression tree was employed to identify three risk categories to assist urologists in selecting candidates for nerve-sparing, incremental nerve sparing and non-nerve-sparing surgery. RESULTS: Overall, data from 3169 hemi-prostates were considered, after the exclusion of prostatic lobes with no biopsy-documented tumor. EPE was present on final pathology in 1,094 (34%) cases. Among these, MRI was able to predict EPE correctly in 568 (52%) cases. A model including PSA, maximum diameter of the index lesion, presence of EPE on MRI, highest ISUP grade in the ipsilateral hemi-prostate, and percentage of positive cores in the ipsilateral hemi-prostate achieved an AUC of 81% after internal validation. Overall, 566, 577, and 2,026 observations fell in the low-, intermediate- and high-risk groups for EPE, as identified by the regression tree. The EPE rate across the groups was: 5.1%, 14.9%, and 48% for the low-, intermediate- and high-risk group, respectively. CONCLUSION: In this study we present an update of the first side-specific MRI-based nomogram for the prediction of extraprostatic extension together with updated risk categories to help clinicians in deciding on the best approach to nerve-preservation.

RESUMO

BACKGROUND: Urinary incontinence (UI) can negatively impact quality of life (QoL) after robot-assisted radical prostatectomy (RARP). Pelvic floor muscle training (PFMT) and duloxetine are used to manage post-RARP UI, but their efficacy remains uncertain. We aimed to investigate the efficacy of PFMT and duloxetine in promoting urinary continence recovery (UCR) after RARP. METHODS: A randomized controlled trial involving patients with urine leakage after RARP from May 2015 to February 2018. Patients were randomized into 1 of 4 arms: (1) PFMT-biofeedback, (2) duloxetine, (3) combined PFMT-biofeedback and duloxetine, (4) control arm. PFMT consisted of pelvic muscle exercises conducted with electromyographic feedback weekly, for 3 months. Oral duloxetine was administered at bedtime for 3 months. The primary outcome was prevalence of continence at 6 months, defined as using ≤1 security pad. Urinary symptoms and QoL were assessed by using a visual analogue scale, and validated questionnaires. RESULTS: From the 240 patients included in the trial, 89% of patients completed 1 year of follow-up. Treatment compliance was observed in 88% (92/105) of patients receiving duloxetine, and in 97% (104/107) of patients scheduled to PFMT-biofeedback sessions. In the control group 96% of patients had achieved continence at 6 months, compared with 90% (p = 0.3) in the PMFT-biofeedback, 73% (p = 0.008) in the duloxetine, and 69% (p = 0.003) in the combined treatment arm. At 6 months, QoL was classified as uncomfortable or worse in 17% of patients in the control group, compared with 44% (p = 0.01), 45% (p = 0.008), and 34% (p = 0.07), respectively. Complete preservation of neurovascular bundles (NVB) (OR: 2.95; p = 0.048) was the only perioperative intervention found to improve early UCR. CONCLUSIONS: PFMT-biofeedback and duloxetine demonstrated limited impact in improving UCR after RP. Diligent NVB preservation, along with preoperative patient and disease characteristics, are the primary determinants for early UCR.

RESUMO

Little is currently known about how climate modulates the relationship between plant diversity and soil organic carbon and the mechanisms involved. Yet, this knowledge is of crucial importance in times of climate change and biodiversity loss. Here, we show that plant diversity is positively correlated with soil carbon content and soil carbon-to-nitrogen ratio across 84 grasslands on six continents that span wide climate gradients. The relationships between plant diversity and soil carbon as well as plant diversity and soil organic matter quality (carbon-to-nitrogen ratio) are particularly strong in warm and arid climates. While plant biomass is positively correlated with soil carbon, plant biomass is not significantly correlated with plant diversity. Our results indicate that plant diversity influences soil carbon storage not via the quantity of organic matter (plant biomass) inputs to soil, but through the quality of organic matter. The study implies that ecosystem management that restores plant diversity likely enhances soil carbon sequestration, particularly in warm and arid climates.

RESUMO

CONTEXT: Whole-gland ablation is a feasible and effective minimally invasive treatment for localized prostate cancer (PCa). Previous systematic reviews supported evidence for favorable functional outcomes, but oncological outcomes were inconclusive owing to limited follow-up. OBJECTIVE: To evaluate the real-world data on the mid- to long-term oncological and functional outcomes of whole-gland cryoablation and high-intensity focused ultrasound (HIFU) in patients with clinically localized PCa, and to provide expert recommendations and commentary on these findings. EVIDENCE ACQUISITION: We performed a systematic review of PubMed, Embase, and Cochrane Library publications through February 2022 according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. As endpoints, baseline clinical characteristics, and oncological and functional outcomes were assessed. To estimate the pooled prevalence of oncological, functional, and toxicity outcomes, and to quantify and explain the heterogeneity, random-effect meta-analyses and meta-regression analyses were performed. EVIDENCE SYNTHESIS: Twenty-nine studies were identified, including 14 on cryoablation and 15 on HIFU with a median follow-up of 72 mo. Most of the studies were retrospective (n = 23), with IDEAL (idea, development, exploration, assessment, and long-term study) stage 2b (n = 20) being most common. Biochemical recurrence-free survival, cancer-specific survival, overall survival, recurrence-free survival, and metastasis-free survival rates at 10 yr were 58%, 96%, 63%, 71-79%, and 84%, respectively. Erectile function was preserved in 37% of cases, and overall pad-free continence was achieved in 96% of cases, with a 1-yr rate of 97.4-98.8%. The rates of stricture, urinary retention, urinary tract infection, rectourethral fistula, and sepsis were observed to be 11%, 9.5%, 8%, 0.7%, and 0.8%, respectively. CONCLUSIONS: The mid- to long-term real-world data, and the safety profiles of cryoablation and HIFU are sound to support and be offered as primary treatment for appropriate patients with localized PCa. When compared with other existing treatment modalities for PCa, these ablative therapies provide nearly equivalent intermediate- to long-term oncological and toxicity outcomes, as well as excellent pad-free continence rates in the primary setting. This real-world clinical evidence provides long-term oncological and functional outcomes that enhance shared decision-making when balancing risks and expected outcomes that reflect patient preferences and values. PATIENT SUMMARY: Cryoablation and high-intensity focused ultrasound are minimally invasive treatments available to selectively treat localized prostate cancer, considering their nearly comparable intermediate- to long term cancer control and preservation of urinary continence to other radical treatments in the primary setting. However, a well-informed decision should be made based on one's values and preferences.

RESUMO

Climate change is leading to species redistributions. In the tundra biome, shrubs are generally expanding, but not all tundra shrub species will benefit from warming. Winner and loser species, and the characteristics that may determine success or failure, have not yet been fully identified. Here, we investigate whether past abundance changes, current range sizes and projected range shifts derived from species distribution models are related to plant trait values and intraspecific trait variation. We combined 17,921 trait records with observed past and modelled future distributions from 62 tundra shrub species across three continents. We found that species with greater variation in seed mass and specific leaf area had larger projected range shifts, and projected winner species had greater seed mass values. However, trait values and variation were not consistently related to current and projected ranges, nor to past abundance change. Overall, our findings indicate that abundance change and range shifts will not lead to directional modifications in shrub trait composition, since winner and loser species share relatively similar trait spaces.

RESUMO

BACKGROUND: Accurate prediction of side-specific extraprostatic extension (ssEPE) is essential for performing nerve-sparing surgery to mitigate treatment-related side-effects such as impotence and incontinence in patients with localised prostate cancer. Artificial intelligence (AI) might provide robust and personalised ssEPE predictions to better inform nerve-sparing strategy during radical prostatectomy. We aimed to develop, externally validate, and perform an algorithmic audit of an AI-based Side-specific Extra-Prostatic Extension Risk Assessment tool (SEPERA). METHODS: Each prostatic lobe was treated as an individual case such that each patient contributed two cases to the overall cohort. SEPERA was trained on 1022 cases from a community hospital network (Trillium Health Partners; Mississauga, ON, Canada) between 2010 and 2020. Subsequently, SEPERA was externally validated on 3914 cases across three academic centres: Princess Margaret Cancer Centre (Toronto, ON, Canada) from 2008 to 2020; L'Institut Mutualiste Montsouris (Paris, France) from 2010 to 2020; and Jules Bordet Institute (Brussels, Belgium) from 2015 to 2020. Model performance was characterised by area under the receiver operating characteristic curve (AUROC), area under the precision recall curve (AUPRC), calibration, and net benefit. SEPERA was compared against contemporary nomograms (ie, Sayyid nomogram, Soeterik nomogram [non-MRI and MRI]), as well as a separate logistic regression model using the same variables included in SEPERA. An algorithmic audit was performed to assess model bias and identify common patient characteristics among predictive errors. FINDINGS: Overall, 2468 patients comprising 4936 cases (ie, prostatic lobes) were included in this study. SEPERA was well calibrated and had the best performance across all validation cohorts (pooled AUROC of 0·77 [95% CI 0·75-0·78] and pooled AUPRC of 0·61 [0·58-0·63]). In patients with pathological ssEPE despite benign ipsilateral biopsies, SEPERA correctly predicted ssEPE in 72 (68%) of 106 cases compared with the other models (47 [44%] in the logistic regression model, none in the Sayyid model, 13 [12%] in the Soeterik non-MRI model, and five [5%] in the Soeterik MRI model). SEPERA had higher net benefit than the other models to predict ssEPE, enabling more patients to safely undergo nerve-sparing. In the algorithmic audit, no evidence of model bias was observed, with no significant difference in AUROC when stratified by race, biopsy year, age, biopsy type (systematic only vs systematic and MRI-targeted biopsy), biopsy location (academic vs community), and D'Amico risk group. According to the audit, the most common errors were false positives, particularly for older patients with high-risk disease. No aggressive tumours (ie, grade >2 or high-risk disease) were found among false negatives. INTERPRETATION: We demonstrated the accuracy, safety, and generalisability of using SEPERA to personalise nerve-sparing approaches during radical prostatectomy. FUNDING: None.

RESUMO

PURPOSE: Bilateral extended pelvic lymph node dissection at the time of radical prostatectomy is the current standard of care if pelvic lymph node dissection is indicated; often, however, pelvic lymph node dissection is performed in pN0 disease. With the more accurate staging achieved with magnetic resonance imaging-targeted biopsies for prostate cancer diagnosis, the indication for bilateral extended pelvic lymph node dissection may be revised. We aimed to assess the feasibility of unilateral extended pelvic lymph node dissection in the era of modern prostate cancer imaging. MATERIALS AND METHODS: We analyzed a multi-institutional data set of men with cN0 disease diagnosed by magnetic resonance imaging-targeted biopsy who underwent prostatectomy and bilateral extended pelvic lymph node dissection. The outcome of the study was lymph node invasion contralateral to the prostatic lobe with worse disease features, ie, dominant lobe. Logistic regression to predict lymph node invasion contralateral to the dominant lobe was generated and internally validated. RESULTS: Overall, data from 2,253 patients were considered. Lymph node invasion was documented in 302 (13%) patients; 83 (4%) patients had lymph node invasion contralateral to the dominant prostatic lobe. A model including prostate-specific antigen, maximum diameter of the index lesion, seminal vesicle invasion on magnetic resonance imaging, International Society of Urological Pathology grade in the nondominant side, and percentage of positive cores in the nondominant side achieved an area under the curve of 84% after internal validation. With a cutoff of contralateral lymph node invasion of 1%, 602 (27%) contralateral pelvic lymph node dissections would be omitted with only 1 (1.2%) lymph node invasion missed. CONCLUSIONS: Pelvic lymph node dissection could be omitted contralateral to the prostate lobe with worse disease features in selected patients. We propose a model that can help avoid contralateral pelvic lymph node dissection in almost one-third of cases.

RESUMO

Introduction: New technologies to improve quality of prostate biopsies are appearing in clinical practice.We evaluate the performance of a micro-ultrasound device and the Prostate Risk Identification using MicroUltraSound (PRI-MUS) score in detecting clinically significant prostate cancer (csPCa). Material and methods: We retrospectively reviewed data of 139 biopsy- naïve patients with suspicion of prostate cancer, who underwent diagnostic MRI and micro-ultrasonography (microUS), followed by transrectal prostatic biopsy (systematic ±targeted) under local anesthetic. The main objective was to evaluate the performance of the Prostate Risk Identification using MicroUltraSound (PRI-MUS) score in detecting csPCa, defined as International Society of Urological Pathology (ISUP) ≥2. Results: Of all patients, 97 (70%) were found to have PCa, and 62 (45%) having csPCa.Among 100 patients with positive microUS (PRI-MUS score ≥3), 23 (23%) had ncsPCa and 57 (57%) were diagnosed with csPCa (ISUP ≥2); and in 39 patients with negative microUS, 12 (31%) were diagnosed with ncsPCa and 5 (13%) with csPCa.A PRI-MUS score ≥3 presented a sensitivity, specificity, positive predictive value and negative predictive value of 92%, 44%, 57% and 95%, respectively, for the detection of csPCa.The PRI-MUS score had higher areas under the curve than Prostate Imaging Reporting & Data System (PI-RADS) both for targeted (AUC 0.801 vs 0.733) and systematic + targeted (AUC 0.776 vs 0.694) biopsies for csPCa detection. Conclusions: In our cohort, microUS performed well as a diagnostic tool through an easily implementable scale. MicroUS presented similar sensitivity and higher specificity than MRI in detecting csPCa. Further multicenter prospective studies may clarify its role in prostate cancer diagnosis.

RESUMO

OBJECTIVES: Localized very high-risk prostate cancer (VHR PCa) has long suffered from the inex-istence of good lymph node staging methods other than invasive surgery, as computed tomogra-phy has low sensitivity for nodal disease. With the rising use of positron emission tomography (PET), it is clinically meaningful to know its value for these patients. Our goal was to evaluate the real-life diagnostic accuracy of PET Choline in nodal staging, comparing it with the gold standard of extended pelvic lymph node dissection (ePLND). MATERIALS AND METHODS: We reviewed data from a high-volume center, including patients with VHR PCa according to current NCCN guidelines who underwent community 18F-fluorocholine PET/CT; followed by ro-botic assisted laparoscopic prostatectomy (RALP) and ePLND between 2010 and 2021. RESULTS: We included 44 patients and 88 lymph node regions. Among those, 14/44 (31.8%) patients and 20/88 (22.7%) regions had nodal disease present on definitive pathology. In comparison with ePLND, we found a sensitivity of 64.3% (95% CI, 39.2-89.4%), specificity of 83.3% (95% CI, 70.0- 96.7%), PPV of 64.3% (95% CI, 39.2-89.4%), and NPV of 83.3% (95% CI, 70.0-96.7%) for nodal disease on a patient-based analysis; and sensitivity of 35.0% (95% CI, 14.1-60.0%), specificity of 88.2% (95% CI, 80.6-95.9%), PPV of 46.7% (95% CI, 21.4-71.9%), and NPV of 82.2% (95% CI, 73.4-91.0%) on a region-based analysis. CONCLUSIONS: In our view 18F-fluorocholine PET/CT doesn't meet the criteria to be a standard exam for pre-operative staging for patients with VHR PCa, mostly due to its low sensitivity. However, other radiotracers should continue to be investigated in this setting.

RESUMO

OBJECTIVES: Focal therapies (FTs) are promising techniques for the treatment of localized prostate cancer. We assessed the medium-term oncological outcomes of intermediate-risk prostate cancer (PCa) treated with HIFU or cryotherapy. MATERIALS AND METHODS: One-hundred and fifty consecutive patients with intermediate-risk PCa, treated between 2009 and 2018 at a single center were included. Primary study outcome was failure-free survival (FFS), defined as absence of additional treatment, systemic progression or prostate cancer related death. RESULTS: Thirty-seven (25%) patients underwent cryotherapy and 113 (75%) HIFU. Median age was 69 (IQR 62-72) years, with 36 (24%) presenting palpable disease on rectal examination, and median total PSA of 7.85 (IQR 5.75-10.62) ng/mL. Patients were followed for a median of 61 (IQR 48-82) months. FFS at 2 and 4 years was of 75.6% and 53.6%, respectively. Survival from whole gland or systematic treatment at 2 and 4 years was of 78.9% and 53.9%, respectively. Patients with FFS presented lower total PSA nadir (1.89 vs 3.25 ng/mL, p < 0.001), higher % PSA reduction at 3 months (66.1% vs 49.3%, p < 0.001), and at nadir (75.5% vs 55.8%, p < 0.001). Other characteristics such has the treatment modality, age, prostate size, initial total PSA, cT stage, International Society of Urological Pathology (ISUP), tumor location and biopsy results by region did not differ between patients failing and not failing FT. Complications were uncommon (13%), with only onr (1%) patient having Clavien-Dindo grade > II. No deaths due to treatment were registered. CONCLUSIONS: At medium-term, FTs for intermediate-risk PCa presented good oncological results, with an excellent safety profile.

RESUMO

INTRODUCTION/BACKGROUND: Only 1 randomized controlled trial has compared focal therapy and active surveillance (AS) for the low-risk prostate cancer (PCa). We investigated whether focal HIFU (fHIFU) yields oncologic advantages over AS for low-risk PCa. MATERIALS AND METHODS: We included 2 non-randomized prospective series of 132 (fHIFU) and 421 (AS) consecutive patients diagnosed with ISUP 1 PCa between 2008 and 2018. A matched pair analysis was performed to decrease potential bias. Study main outcomes were freedom from radical treatment (RT) or androgen-deprivation therapy (ADT), treatment-free survival (TFS), time to metastasis, and overall survival (OS). RESULTS: Median fHIFU follow-up was 50 months (interquartile range, 29-84 months). Among matched variables, no major differences were recorded except for AS having more suspicious digital rectal examination findings (P = .0074) and recent enrollment year (P = .0005). Five-year intervention-free survival from RT or ADT was higher for the fHIFU cohort (67.4% vs. 53.8%; P = .0158). Time to treatment was approximately 10 months shorter for AS than for fHIFU (time to RT, P = .0363; time to RT or ADT, P = .0156; time to any treatment, P = .0319). No differences were found in any-TFS (fHIFU, 61.4% vs. AS, 53.8%; P = .2635), OS (fHIFU, 97% vs. AS, 97%; P = .9237), or metastasis (n = 0 in fHIFU and n = 2 in AS; P = .4981). Major complications (≥ Clavien 3) were rare (n = 4), although 36.4% of men experienced complications. No relevant changes were noted in continence (P = .3949). CONCLUSION: At a 4-year median follow-up, fHIFU for mainly low-risk PCa (ISUP grade 1) is safe, may decrease the need for radical treatment or ADT and may allow longer time to treatment compared to AS. Nonetheless, no advantages are seen in PCa progression and/or death (OS).

RESUMO

While the assumption that the sociopolitical and economic situation affects adolescents' well-being, encompassing life satisfaction and a positive sense of self, is plausible, few studies have confirmed such macrosocial influences. The case of the Czech Republic offers an example of a society transitioning from totalitarian government (from 1989) to western democracy. Our study provides statistical description of Czech adolescents' well-being over the past 30 years in association with the subjective perception of everyday problems. These daily hassles represent experiences and conditions of daily living that have been appraised as salient and harmful or threatening to adolescents' well-being. We analyzed four samples of adolescents aged 14-17 years surveyed at four time points over the last three decades-1992, 2001, 2011, and 2019, total N = 4,005 (1992: 255, 2001: 306, 2011: 363, 2019: 3081; 54.6% females). The results show that life satisfaction, self-esteem, and self-reported daily hassles changed only marginally from 1992 to 2019 with small differences related to the post-revolution 1992 cohort. Adolescents reported increasing problems in school, relationships with parents, sports, and leisure time over the study period. A model linking daily hassles and self-esteem to life satisfaction across four cohorts showed that daily hassles strongly predicted life satisfaction except in the post-revolution cohort of 1992 when life satisfaction was also the lowest. The effect was slightly higher in females. Across the cohorts, gender differences in life satisfaction changed from males being more satisfied in 1992 to females being more satisfaction in 2019. Limitations stemming from sampling differences across cohorts are discussed.

RESUMO

Life satisfaction, an important precursor of adolescents' well-being, is linked to daily activities. Substantial changes have been noted in adolescents' daily activities over the years, raising the question of possible consequences for life satisfaction. This study aimed to explore changes in adolescents' life satisfaction and their time spent on daily activities (sleeping, engaging in sports, online gaming, school commuting, time spent at school) and further investigate the associations between adolescents' life satisfaction and these daily activities. The sample comprised 2715 adolescents from birth cohorts surveyed at four time points between 1992 and 2019. Participants were administered the Daily Activities Inventory and the Berne Questionnaire on Adolescents' Well-Being. Robust ANOVA with post hoc tests and spline regression were employed. We found cohort differences in sleep duration (8.6 h a day on average in 1992 and 7.5 in 2019). Sleep duration of 8 h and 1 h of sports activities had a beneficial effect on life satisfaction, while more than 1 h of online gaming had a negative impact. Neither school attendance nor commuting to school was associated with adolescents' life satisfaction. The results of this study can inform public-health policies to promote sleeping and sports habits in adolescence.

RESUMO

Objects: Health Behaviours in School-aged Children (HBSC) is an international survey programme aiming to investigate adolescents' health behaviours, subjective perception of health status, wellbeing, and the related contextual information. Our scoping review aimed to synthesise the evidence from HBSC about the relationship between family environmental contributors and adolescents' health-related outcomes. Methods: We searched previous studies from six electronic databases. Two researchers identified the qualified publications independently by abstract and full-text screening with the assistance of an NLP-based AI instrument, ASReview. Publications were included if they were based on HBSC data and investigated the effects of family environment on adolescents' health outcomes. Researches addressed family-related factors as mediators or moderators were also included. Results: A total of 241 articles were included. Family environmental contributors could be mapped into six categories: (1) Demographic backgrounds (N = 177); (2) General family's psycho-socio functions (N = 44); (3) Parenting behaviours (N = 100); (4) Parental health behaviours (N = 7); (5) Family activities (N = 24); and (6) Siblings (N = 7). Except for 75 papers that assessed family variables as moderators (N = 70) and mediators (N = 7), the others suggested family environment was an independent variable. Only five studies employed the data-driven approach. Conclusion: Our results suggest most research studies focussed on the influences of family demographic backgrounds on adolescents' health. The researches related to parental health behaviours and siblings are most inadequate. Besides, we recommend further research studies to focus on the mediator/moderator roles of the family, for exploring the deep mechanism of the family's impacts. Also, it would be valuable to consider data-driven analysis more in the future, as HBSC has mass variables and data.

RESUMO

While biodiversity is expected to enhance multiple ecosystem functions (EFs), the different roles of multiple biodiversity dimensions remain difficult to disentangle without carefully designed experiments. We sowed plant communities with independent levels of functional (FD) and phylogenetic diversities (PD), combined with different levels of fertilization, to investigate their direct and indirect roles on multiple EFs, including plant-related EFs (plant biomass productivity, litter decomposability), soil fertility (organic carbon and nutrient pool variables), soil microbial activity (respiration and nutrient cycling), and an overall multifunctionality. We expected an increase in most EFs in communities with higher values of FD and/or PD via complementarity effects, but also the dominant plant types (using community weighted mean, CWM, independent of FD and PD) via selection effects on several EFs. The results showed strong direct effects of different dimensions of plant functional structure parameters on plant-related EFs, through either CWM or FD, with weak effects of PD. Fertilization had significant effects on one soil microbial activity and indirect effects on the other variables via changes in soil abiotic properties. Dominant plant types and FD showed only indirect effects on soil microbial activity, through litter decomposition and soil abiotic properties, highlighting the importance of cascading effects. This study shows the relevance of complementary dimensions of biodiversity for assessing both direct and cascading effects on multiple EFs.

RESUMO

PURPOSE: Non-muscle-invasive bladder cancers (NMIBC) constitute 3-quarters of all primary diagnosed bladder tumors. For risk-adapted management of patients with NMIBC, different risk group systems and predictive models have been developed. This study aimed to externally validate EORTC2016, CUETO and novel EAU2021 risk scoring models in a multi-institutional retrospective cohort of patients with high-grade NMIBC who were treated with an adequate BCG immunotherapy. METHODS: The Kaplan-Meier estimates for recurrence-free survival and progression-free survival were performed, predictive abilities were assessed using the concordance index (C-index) and area under the curve (AUC). RESULTS: A total of 1690 patients were included and the median follow-up was 51 months. For the overall cohort, the estimates recurrence-free survival and progression-free survival rates at 5-years were 57.1% and 82.3%, respectively. The CUETO scoring model had poor discrimination for disease recurrence (C-index/AUC for G2 and G3 grade tumors: 0.570/0.493 and 0.559/0.492) and both CUETO (C-index/AUC for G2 and G3 grade tumors: 0.634/0.521 and 0.622/0.525) EAU2021 (c-index/AUC: 0.644/0.522) had poor discrimination for disease progression. CONCLUSION: Both the CUETO and EAU2021 scoring systems were able to successfully stratify risks in our population, but presented poor discriminative value in predicting clinical events. Due to the lack of data, model validation was not possible for EORTC2016. The CUETO and EAU2021 systems overestimated the risk, especially in highest-risk patients. The risk of progression according to EORTC2016 was slightly lower when compared with our population analysis.

RESUMO

Negative experiences in school predict adolescents' depression. However, the dynamic interactions of depressive symptoms with adolescents' negative experiences in school remain unclear. This study aimed to applied network analysis to detect the complex relationships between early adolescents' depressive symptoms and negative experiences in school. We adopted the data from a Chinese national survey conducted in 2018. Eight hundred ninety-seven adolescents from 10 to 15 years old were included. The measurements included an 8-item depression screener scale and a 14-item scale assessing negative experiences in school. The centrality analysis suggested that Chinese early adolescents' core depressive symptoms were negative affections. Regarding "negative experiences in the school," the most central nodes were poor academic performance and peer relationships. The bridge-centrality results showed negative emotions in school and difficulties in peer relationships were significantly linked to depression. Educators should pay attention to adolescents' negative affection and difficulties in peer relationships in school settings because they are potential signs of depression. Relevant peer support intervention aiming for adolescents' social development should be underscored.
