Trial Participation is Not Associated with Better Biochemical Recurrence-free Survival in a Large Cohort of External Beam Radiotherapy-Treated Intermediate- and High-Risk Prostate Cancer Patients.

AIMS: There is a widespread belief that outcomes of cancer patients treated within clinical trials might not be representative of the outcomes obtained within standard clinical settings. We sought to investigate the effect of trial participation on biochemical recurrence (BCR) in localised, D'Amico intermediate- and high-risk prostate cancer patients treated with external beam radiotherapy (EBRT). MATERIALS AND METHODS: We relied on a study population treated with EBRT between January 2001 and January 2021 at a single tertiary care centre, stratified according to trial enrolment. Separate Kaplan-Meier and multivariable Cox regression models tested BCR-free survival at 60 months within intermediate- and high-risk EBRT patients, after adjustment for covariables. Additionally, the analyses were refitted after inverse probability treatment weighting was performed separately for both risk subgroups. RESULTS: Of 932 eligible patients, 635 (68%) and 297 (32%) had intermediate- and high-risk prostate cancer, respectively. Overall, 53% of patients were trial participants. BCR rates were 11 versus 5% (P = 0.27) and 12 versus 14% (P = 0.08) in trial participants versus non-participants for intermediate- and high-risk subgroups, respectively. Differences in patient and clinical characteristics were recorded. Trial participation status failed to reach predictor status in multivariable Cox regression models for BCR in both intermediate-risk (hazard ratio 1.34; 95% confidence interval 0.71-2.49; P = 0.4) and high-risk patients (hazard ratio 1.03; 95% confidence interval 0.45-2.34; P = 0.9). Virtually the same results were recorded in inverse probability treatment weighting cohorts. CONCLUSIONS: Relying on a large cohort of EBRT-treated intermediate- and high-risk patients, no BCR differences were recorded between trial participants and non-participants after accounting for confounders.

'Value-based methodology for person-centred, integrated care supported by Information and Communication Technologies' (ValueCare) for older people in Europe: study protocol for a pre-post controlled trial.

BACKGROUND: Older people receive care from multiple providers which often results in a lack of coordination. The Information and Communication Technology (ICT) enabled value-based methodology for integrated care (ValueCare) project aims to develop and implement efficient outcome-based, integrated health and social care for older people with multimorbidity, and/or frailty, and/or mild to moderate cognitive impairment in seven sites (Athens, Greece; Coimbra, Portugal; Cork/Kerry, Ireland; Rijeka, Croatia; Rotterdam, the Netherlands; Treviso, Italy; and Valencia, Spain). We will evaluate the implementation and the outcomes of the ValueCare approach. This paper presents the study protocol of the ValueCare project; a protocol for a pre-post controlled study in seven large-scale sites in Europe over the period between 2021 and 2023. METHODS: A pre-post controlled study design including three time points (baseline, post-intervention after 12 months, and follow-up after 18 months) and two groups (intervention and control group) will be utilised. In each site, (net) 240 older people (120 in the intervention group and 120 in the control group), 50-70 informal caregivers (e.g. relatives, friends), and 30-40 health and social care practitioners will be invited to participate and provide informed consent. Self-reported outcomes will be measured in multiple domains; for older people: health, wellbeing, quality of life, lifestyle behaviour, and health and social care use; for informal caregivers and health and social care practitioners: wellbeing, perceived burden and (job) satisfaction. In addition, implementation outcomes will be measured in terms of acceptability, appropriateness, feasibility, fidelity, and costs. To evaluate differences in outcomes between the intervention and control group (multilevel) logistic and linear regression analyses will be used. Qualitative analysis will be performed on the focus group data. DISCUSSION: This study will provide new insights into the feasibility and effectiveness of a value-based methodology for integrated care supported by ICT for older people, their informal caregivers, and health and social care practitioners in seven different European settings. TRIAL REGISTRATION: ISRCTN registry number is 25089186 . Date of trial registration is 16/11/2021.

Late complications of robot-assisted radical cystectomy with totally intracorporeal urinary diversion.

INTRODUCTION AND OBJECTIVES: To evaluate late complications in a large cohort of patients undergoing robot-assisted radical cystectomy (RARC) with totally intracorporeal urinary diversion (ICUD). MATERIALS AND METHODS: We prospectively enrolled patients who underwent RARC and ICUD between August 2012 and June 2019. We excluded patients with Ejection fraction < 36%, retinal vasculopathy, ventriculoperitoneal shunts, and those treated without curative intent. All complications and their onset date have been recorded, defined, and graded according to Clavien classification adapted for radical cystectomy. RESULTS: 210 patients were included, 76% of whom were men, with a mean age of 62 years. Urinary diversions used were Padua Ileal Bladder (PIB) in 80% of cases, and ileal conduit (IC) in 20% of patients (generally older and with more comorbidity). The mean follow-up was 30 ± 22 months. The stenosis rate of uretero-ileal anastomosis was 14%, while a reduction in eGFR (≥ 20%) was observed in about half of the cases. UTIs occurred in 37% of the patients, especially in the first 12 months. Only 2% of patients had bowel occlusion, whereas incisional hernia, lymphocele, and systemic events (metabolic acidosis and major cardiovascular events) occurred respectively in 20%, 10%, and 1% of cases. CONCLUSIONS: Our study evaluates first late complications in a cohort of patients who underwent RARC with ICUD. These data are encouraging and in line with findings from a historical series of open radical cystectomy (ORC). This study is a further step in supporting RARC as a safe and effective surgical option for the treatment of muscle-invasive bladder cancer (MIBC) in tertiary referral centers.

The cortisol burden in elderly subjects with metabolic syndrome and its association with low-grade inflammation.

BACKGROUND: Elderly people are exposed to an increased load of stressful events and neuro-hormonal stimulation is a key finding in metabolic syndrome and its related disorders. AIMS: To determine the role of cortisol in elderly subjects, with or without metabolic syndrome (MetS), by means of a national multicentre observational study, AGICO (AGIng and Cortisol). METHODS: From 2012 to 2017, the AGICO study enrolled n.339 subjects (aged > 65), after obtaining their informed consent. The investigators assessed a cardio-metabolic panel (including electrocardiogram, carotid ultrasonography and echocardiography), the presence of MetS (on Adult Treatment Panel III criteria), a neurological examination (including brain imaging), and cortisol activity (using a consecutive collection of diurnal and nocturnal urine). RESULTS: In the patients presenting with MetS, the standardized diurnal and nocturnal cortisol excretion rates were 210.7 ± 145.5 and 173.7 ± 118.1 (mean ± standard deviation) µg/g creatinine/12 h; in those without MetS, the standardized diurnal and nocturnal cortisol excretion rates were 188.7 ± 92.7 and 144.1 ± 82.3 µg/g creatinine/12 h, respectively (nocturnal urinary cortisol in patients with MetS versus those without MetS p = 0.05, female patients with MetS vs female patients without MetS, p < 0.025). A significant positive correlation was found between the CRP levels and both the diurnal and nocturnal urinary cortisol levels with r = 0.187 (p < 0.025) and r = 0.411 (p < 0.00000001), respectively. DISCUSSION: The elderly patients with MetS showed a trend towards increased standardized nocturnal cortisol excretions, with particular regard to the female subjects. CONCLUSION: The positive correlation between cortisol excretion and low-grade inflammation suggests a common mechanism driving both hormonal and inflammatory changes.

Best practices in near-infrared fluorescence imaging with indocyanine green (NIRF/ICG)-guided robotic urologic surgery: a systematic review-based expert consensus.

PURPOSE: The aim of the present study is to investigate the impact of the near-infrared (NIRF) technology with indocyanine green (ICG) in robotic urologic surgery by performing a systematic literature review and to provide evidence-based expert recommendations on best practices in this field. METHODS: All English language publications on NIRF/ICG-guided robotic urologic procedures were evaluated. We followed the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) statement to evaluate PubMed®, Scopus® and Web of Science™ databases (up to April 2019). Experts in the field provided detailed pictures and intraoperative video-clips of different NIRF/ICG-guided robotic surgeries with recommendations for each procedure. A unique QRcode was generated and linked to each underlying video-clip. This new exclusive feature makes the present the first "dynamic paper" that merges text and figure description with their own video providing readers an innovative, immersive, high-quality and user-friendly experience. RESULTS: Our electronic search identified a total of 576 papers. Of these, 36 studies included in the present systematic review reporting the use of NIRF/ICG in robotic partial nephrectomy (n = 13), robotic radical prostatectomy and lymphadenectomy (n = 7), robotic ureteral re-implantation and reconstruction (n = 5), robotic adrenalectomy (n = 4), robotic radical cystectomy (n = 3), penectomy and robotic inguinal lymphadenectomy (n = 2), robotic simple prostatectomy (n = 1), robotic kidney transplantation (n = 1) and robotic sacrocolpopexy (n = 1). CONCLUSION: NIRF/ICG technology has now emerged as a safe, feasible and useful tool that may facilitate urologic robotic surgery. It has been shown to improve the identification of key anatomical landmarks and pathological structures for oncological and non-oncological procedures. Level of evidence is predominantly low. Larger series with longer follow-up are needed, especially in assessing the quality of the nodal dissection and the feasibility of the identification of sentinel nodes and the impact of these novel technologies on long-term oncological and functional outcomes.

Heart Rate Variability reveals the fight between racially biased and politically correct behaviour.

In this study, we explored vagally-mediated heart rate variability (vmHRV) responses, a psychophysiological index of cognitive self-regulatory control, to map the dynamics associated with empathic responses for pain towards an out-group member. Accordingly, Caucasian participants were asked to judge the experience of African and Caucasian actors touched with either a neutral or a harmful stimulus. Results showed that (1) explicit judgment of pain intensity in African actors yielded higher rating score and (2) took longer time compared to Caucasian actors, (3) these behavioural outcomes were associated with a significant increment of RMSSD, Log-HF-HRV and HF-HRV n.u., (4) resting HF-HRV n.u. predicted the participants' lag-time to judge painful stimulations delivered to African actors. Interestingly, these dynamics were associated with a measure of implicit racial attitudes and were, in part, abolished when participants performed a concurrent task during videos presentation. Taken together our results support the idea that a cognitive effort is needed to self-regulate our implicit attitude as predicted by the 'Contrasting Forces Model'.

Pharmacomechanical catheter-directed thrombolysis for acute iliofemoral deep vein thrombosis: our case series.

OBJECTIVE: This is a retrospective study on Pharmacomechanical Catheter-Directed Thrombolysis (PCDT) in the treatment of acute iliofemoral Deep Vein Thrombosis (DVT). PATIENTS AND METHODS: From March 2013 to November 2016, 22 patients (26 limbs), median age 46.7 years with acute (<21 days) extensive iliofemoral DVT underwent Percutaneous Mechanical Thrombectomy (PMT) with Aspirex (Straub Medical, Wangs, Switzerland), followed by Catheter-Directed Thrombolysis (CDT). Subsequent endovascular stenting was performed for underlying obstruction. The follow-ups were conducted up to 1 year, in two Centers by experienced operators. Post-Thrombotic Syndrome (PTS) was evaluated by assessing the Villalta Scale (VS) and measuring orthostatic venous pressure. RESULTS: Post-operative iliofemoral vein patency was restored in almost all cases (95.5%). Standard urokinase dose was 80.000 IU per hour; mean infusion time was 32.5 hours. Stenting was performed in 15 cases (68%). Median follow-up was 19.9 months (6-48 months); 21/22 patients completed the 12 months follow-up. At 30 days follow-up symptoms disappeared in 21/22 cases (95.5%), with one case (4.5%) of DVT recurrence. At 1-year follow-up there were 3 cases (14.2%) of mild PTS; 18 patients (85.8%) were free from PTS. At 1-year follow-up venous pressure measurement showed normal values in 11 cases (52.4%), mild hypertension in 7 patients (33.3%), moderate hypertension (80-100 mmHg) in 2 cases (9.5%) and severe hypertension (110 mmHg) in one case (4.8%). Neither major nor minor complications were observed. CONCLUSIONS: PMT with Aspirex combined with CDT with urokinase seems to be a safe and effective treatment for acute iliofemoral DVT and it shows promising results in reducing the risk of PTS. Thus, we suggest a controlled trial with this treatment strategy.

Cough and airway clearance in Duchenne muscular dystrophy.

People with Duchenne muscular dystrophy (DMD), develop a respiratory muscle weakness that results in weakened cough, airway clearance impairment and over time respiratory failure and death. Assessment of cough effectiveness through vital capacity, peak cough flow and maximal inspiratory and expiratory pressures has been used to identify the optimal timing of cough augmentation techniques initiation. The choice of therapies depends on physician knowledge, and patient/care giver abilities. The purpose of this review is to clarify mechanisms of action, benefits and disadvantages of available techniques, such as manual cough-assisting manoeuvres, glossopharyngeal breathing, air stacking by resuscitator bag or by volume-cycle ventilator, and mechanical insufflator-exsufflator. Mechanisms of mucus mobilization, like intrapulmonary percussive ventilation, may have a therapeutic role in the case of persistent atelectasis. It is also crucial to recognize the initial phase of an acute respiratory exacerbation, increase the use of these techniques which may reduce morbidity and mortality.

Papillary type 2 versus clear cell renal cell carcinoma: Survival outcomes.

AIM: To compare the cancer specific survival (CSS) between p2-RCC and a Propensity Score Matched (PSM) cohort of cc-RCC patients. METHODS: Fifty-five (4.6%) patients with p2-RCC and 920 cc-RCC patients were identified within a prospectively maintained institutional dataset of 1205 histologically proved RCC patients treated with either RN or PN. Univariable and multivariable Cox regression analyses were used to identify predictors of CSS after surgical treatment. A 1:2 PSM analysis based on independent predictors of oncologic outcomes was employed and CSS was compared between PSM selected cc-RCC patients using Kaplan-Meier and Cox regression analysis. RESULTS: Overall, 55 (4.6%) p2-RCC and 920 (76.3%) cc-RCC patients were selected from the database; p2-RCC were significantly larger (p = 0.001), more frequently locally advanced (p < 0.001) and node positive (p < 0.001) and had significantly higher Fuhrman grade (p < 0.001) than cc-RCC. On multivariable Cox regression analysis age (p = 0.025), histologic subtype (p = 0.029), pN stage (p = 0.006), size, pT stage, cM stage, sarcomatoid features and Fuhrman grade (all p < 0.001) were independent predictors of CSS. After applying the PSM, 82 cc-RCC selected cases were comparable to 41 p2-RCC for age (p = 0.81), tumor size (p = 0.39), pT (p = 1.00) and pN (p = 0.62) stages, cM stage (p = 0.71) and Fuhrman grade (p = 1). In this PSM cohort, 5 yr CSS was significantly lower in the p2-RCC (63% vs 72.4%; p = 0.047). At multivariable Cox analysis p2 histology was an independent predictor of CSM (HR 2.46, 95% CI 1.04-5.83; p = 0.041). CONCLUSIONS: We confirmed the tendency of p2-RCC to present as locally advanced and metastatic disease more frequently than cc-RCC and demonstrated p2-RCC histology as an independent predictor of worse oncologic outcomes.

Daily life changes and adaptations investigated in 154 families with a child suffering from a rare disability at a public centre for rare diseases in Northern Italy.

BACKGROUND: Living with a disabled child has profound effects on the entire family. With a prevalence of developmental disabilities around 2,5 %, there is a considerable need to promote improvements in the health care system. Little is known about changes and adaptations in the lives of affected families and this paucity of information hinders the improvement of services. This study sought to explore the needs and changes in the everyday life of families with children suffering from rare diseases of varying severity, with and without mental disability. The aim was to measure the socio-demographic characteristics, health care problems and living conditions of a large cohort of families with an affected member. METHODS: A sample of 154 families was recruited between September 2011 and April 2013 to respond to a 136 item questionnaire that explored different areas of concern (diagnosis and follow-up of clinical specialists, relationship with pediatrician, rehabilitation, school, work, institutional and/or private support, child care needs and family relationships). RESULTS: All parents answered the questionnaire. They were satisfied with the services provided in particular for diagnosis and follow-up, relationships with the family pediatrician, rehabilitation services and school, regardless of the severity of condition, presence of intellectual disability (ID) or absence of diagnosis. Negative scores were reported for institutional and/or private support and family relationships in severe conditions. CONCLUSIONS: The Health Care System should maintain a family-centered care and a multi-agency working, improving quality of life of families with disabled child to allow adaptation. At present these services are uncoordinated and financial support is poor, resulting in a heavy burden for these families.

Guess who's coming to dinner: Brain signatures of racially biased and politically correct behaviors.

The ability to share feelings with those of someone in pain is affected by the racial difference between the target and the onlooker. A differential empathic activation for race (DEAR effect) in favor of in-group members has been documented in the brain pain matrix. However, we are also capable of unbiased responses that manifest politically correct behaviors toward people of a different race. To address the neurofunctional signatures underlying both the DEAR effect and the manifestation of politically correct behaviors, we scanned with fMRI Caucasian participants while watching African or Caucasian actors touched by either a rubber eraser or a needle. Participants were instructed to empathize with the actors during the video presentation (stimulus phase) and to explicitly judge the pain level experienced by the actors (response phase). During the stimulus phase, we found a typical DEAR effect within the pain-matrix. This effect correlated with the level of implicit racial bias as measured by the IAT. On the other hand, during the response phase a significant out-group specific DEAR effect emerged in the prefrontal cortices. This latter effect was coupled with a revealing behavioral pattern: while the magnitude of the painful experience attributed to Caucasians and Africans was the same, our participants were significantly slower when judging the pain experience of the African actors. We propose a model that logically integrates these two contrasting forces at the neurobiological and behavioral level.

Trends in the use of partial nephrectomy for cT1 renal tumors: Analysis of a 10-yr European multicenter dataset.

AIM: Although extensively addressed in US registries, the utilization rate of Partial Nephrectomy has been poorly addressed in European settings. Our aim is to evaluate the impact of hospital volume on the use of PN for cT1 renal tumors. METHODS: 2526 patients with cT1N0M0 renal tumors treated with either PN or radical nephrectomy at 10 European centres in the last decade were included in the analysis. Joinpoint regression analysis was used to identify significant changes over time in linear slope of the trend for each center. The correlation between yearly caseload and the slopes was assessed with the non-parametric Spearman test. Coincident pairwise tests and regression analyses were used to generate and compare the trends of high-volume (HV), mid-volume (MV) and low-volume (LV) groups. RESULTS: Yearly caseload was significantly associated with increased use of PN (R = 0.69, p = 0.028). The utilization rate of PN was stable at LV centres (p = 0.67, p = 0.7, p = 0.76, for cT1, cT1a, and cT1b tumors, respectively), while increased significantly at MV (p = 0.002, 0.0005 and 0.007, respectively) and HV centers (all p < 0.0001). Regression analysis confirmed the trends for HV and MV as significantly different from those observed in LV centres (all p ≤ 0.002) and highlighted significant differences also between MV and HV centres (all p ≤ 0.03). CONCLUSIONS: We confirmed the association between caseload and the use of PN for cT1 tumors. Our findings suggest that a minimum caseload might turn the tide also in LV centres while a selective referral to HV centers for cT1b tumors should be considered.

Microparticles based on chitosan/carboxymethylcellulose polyelectrolyte complexes for colon delivery of vancomycin.

The aim of this work was to prepare polyelectrolyte complexes based on chitosan (CH) and carboxymethylcellulose (CMC) for colon delivery of vancomycin (VM). Various batches of polyelectrolyte complexes, using three different CH/CMC weight ratios (3:1, 1:1 and 1:3), were prepared and collected as microparticles by spray-drying process. Microparticles were characterized in terms of yield, encapsulation efficiency, drug loading, morphology and mucoadhesion properties. Microparticles water-uptake and VM release as well as its protection against gastric pepsin degradation were also investigated. Finally, the antibacterial activity against Staphylococcus aureus, a Gram-positive model strain, was evaluated. The best formulation CH/CMC 1:3 was selected based on the encapsulation efficiency, water-uptake and drug release rate. Moreover, microparticles were able to prevent VM degradation and showed a good antibacterial activity against S. aureus. Finally, to improve the release of VM in the colon the selected formulation was coated with lauric acid.

Association between the Mediterranean-style Dietary Pattern Score and Physical Performance: Results from TRELONG Study.

OBJECTIVE: To determine the association between Mediterranean-Style Dietary Pattern Score and physical performance. DESIGN: Data analysis of a longitudinal study of a representative, age stratified, population sample. SETTING: The TREVISO LONGEVA (TRELONG) Study, in Treviso, Italy. PARTICIPANTS: In 2010, 123 men and 181 women, age 77 years and over (mean age 86.3 ± 6.8 years). MEASUREMENTS: Performing a logistic regression in a multivariate analysis, hand grip strength and Short Physical Performance Battery (SPPB) were tested in relation to Mediterranean-Style Dietary Pattern Score (MSDPS). RESULTS: The hand grip mean value was 10.9 kg (± 9.5) and the SPPB score was 6.3 (± 3.8). The MSDPS mean value in this study sample was 38.1/100 (± 8.1). A significant association (p=0.036) between a high adherence to the Mediterranean diet (fourth quartile) and higher performance lower limbs (SPPB>7) was found. No correlation was reported for the hand grip strength. CONCLUSION: We found an association statistically significant between a high adherence to the Mediterranean diet and higher physical performance.

A microRNA code for prostate cancer metastasis.

Although the development of bone metastasis is a major detrimental event in prostate cancer, the molecular mechanisms responsible for bone homing and destruction remain largely unknown. Here we show that loss of miR-15 and miR-16 in cooperation with increased miR-21 expression promote prostate cancer spreading and bone lesions. This combination of microRNA endows bone-metastatic potential to prostate cancer cells. Concomitant loss of miR-15/miR-16 and gain of miR-21 aberrantly activate TGF-ß and Hedgehog signaling, that mediate local invasion, distant bone marrow colonization and osteolysis by prostate cancer cells. These findings establish a new molecular circuitry for prostate cancer metastasis that was validated in patients' cohorts. Our data indicate a network of biomarkers and druggable pathways to improve patient treatment.

Chitosan based micro- and nanoparticles for colon-targeted delivery of vancomycin prepared by alternative processing methods.

The aim of this work was to prepare chitosan (CH) based particulate formulations for colon delivery of vancomycin (VM). Chitosan microparticles (MPs) and nanoparticles (NPs) loaded with VM were prepared using different CH/tripolyphosphate (TPP) molar ratios and different technological processes. In particular, nanoparticles were prepared by ionic gelation and freeze-drying to recover these particles, or, alternatively, by spray-drying method. Microparticles were prepared using a different spray-dryer. Micro- and nanoparticles were characterized in terms of size distributions by photon correlation spectroscopy (PCS), while encapsulation and drug loading efficiencies were studied using a dialysis method. Fourier Transform Infrared Spectroscopy (FT-IR) was employed to determine the surface composition of the micro- and nanoparticles respectively, and the morphologies of the developed systems were studied by scanning electron microscopy (SEM). Water uptake as well as drug release profiles were also measured. Antibacterial activity against Staphylococcus aureus, a Gram-positive model strain, was evaluated. FT-IR results suggested an electrostatic interaction between VM and CH/TPP particles. Moreover, the particles were found to hold a positive zeta-potential, indicating the presence of CH on the particle surfaces. Particle size and encapsulation efficiency were mainly influenced by the different manufacturing processes employed. Nanoparticles obtained by spray-drying showed the best results in terms of water uptake and drug release rate. Moreover, they showed a good bactericidal activity against S. aureus.

In vitro activity of natural phenolic compounds against fluconazole-resistant Candida species: a quantitative structure-activity relationship analysis.

AIMS: To evaluate the antifungal activity and to analyse the structure-activity relationship of eleven natural phenolic compounds against four Candida species which are resistant to fluconazole. METHODS AND RESULTS: Four different species of Candida isolates were used: Candida albicans, Candida krusei, Candida tropicalis and Candida dubliniensis. The phenolic compound carvacrol showed the highest anti-Candida bioactivity, followed by thymol and isoeugenol. The obtained minimum inhibitory concentration (MIC) values obtained were used in a quantitative structure-activity relationship (QSAR) analysis where the electronic, steric, thermodynamic and topological descriptors served as dependent variables. According to the descriptors obtained in this QSAR study, the antifungal activity of phenols has a first action specific character which is based on their interaction with plasma or mitochondrial membranes. The second action is based on a steric descriptor-the maximal and minimal projection of the area-which could explain the inability of some phenolic compounds to be biotransformed to quinones methylene by Candida species. CONCLUSIONS: According to the descriptors obtained in this QSAR study, the anti-Candida activity of ortho-substituted phenols is due to more than one action mechanism. The anti-Candida activity of phenolic compounds can be predicted by their molecular properties and structural characteristics. SIGNIFICANCE AND IMPACT OF THE STUDY: These results could be employed to predict the anti-Candida activity of new phenolic compounds in the search for new alternatives or complementary therapies to combat against candidiasis.

MR assessment of lumbar disk herniation treated with oxygen-ozone diskolysis: the role of DWI and related ADC versus intervertebral disk volumetric analysis for detecting treatment response.

We prospectively assessed the diagnostic criteria of morphologic MRI study (MMS) and the accuracy of DWI and related ADC values (DWI-ADC) versus intervertebral disk volumetric analysis (IDVA) for predicting shrinkage of lumbar disk herniation treated with oxygen-ozone (O2-O3) diskolysis. Sixty-eight patients (36 men and 32 women; mean age 39) with lumbosciatica underwent O2-O3 diskolysis. The six-month MRI follow-up was performed with FSE-T2 and T2-fat, SE-T1 and DWI-weighted images. IDVA was determined using OsiriX(®). Diagnostic criteria and accuracy were evaluated with regards to DWI and related ADC in detecting response to ozone therapy. Fifty-eight of 68 patients had successful outcomes (responders), whereas ten patients showed unsatisfactory outcomes (non-responders). MMS showed that a centrally located herniated disk and grade 1 nerve root compression were more common in the responder group (p < 0.05). DWI-ADC and IDVA showed statistically significant shrinkage in the sixth month of follow-up (p < 0.05) with a mean ADC value reduction of 2.10 × 10(-3) mm(2)/s +/- 0.19 SD in the second month of follow-up (p < 0.05). DWI-ADC had an accuracy of 0.81 in detecting response to therapy around the second month of follow-up. DWI-ADC appear to be useful adjuncts to MMS in the follow-up of patients undergoing O2-O3 diskolysis.

Analysis of radical cystectomy and urinary diversion complications with the Clavien classification system in an Italian real life cohort.

INTRODUCTION: Standardized methods of reporting complications after radical cystectomy (RC) and urinary diversions (UD) are necessary to evaluate the morbidity associated with this operation to evaluate the modified Clavien classification system (CCS) in grading perioperative complications of RC and UD in a real life cohort of patients with bladder cancer. MATERIALS AND METHODS: A consecutive series of patients treated with RC and UD from April 2011 to March 2012 at 19 centers in Italy was evaluated. Complications were recorded according to the modified CCS. Results were presented as complication rates per grade. Univariate and binary logistic regression analysis were used for statistical analysis. RESULTS AND LIMITATIONS: 467 patients were enrolled. Median age was 70 years (range 35-89). UD consisted in orthotopic neobladder in 112 patients, ileal conduit in 217 patients and cutaneous ureterostomy in 138 patients. 415 complications were observed in 302 patients and were classified as Clavien type I (109 patients) or II (220 patients); Clavien type IIIa (45 patients), IIIb (22 patients); IV (11 patients) and V (8 patients). Patients with cutaneous ureterostomy presented a lower rate (8%) of CCS type ≥IIIa (p = 0.03). A longer operative time was an independent risk factor of CCS ≥III (OR: 1.005; CI: 1.002-1.007 per minute; p = 0.0001). CONCLUSIONS: In our study, RC is associated with a significant morbidity (65%) and a reduced mortality (1.7%) when compared to previous experiences. The modified CCS represents an easily applicable tool to classify the complications of RC and UD in a more objective and detailed way.

Body mass index, lifestyles, physical performance and cognitive decline: the "Treviso Longeva (TRELONG)" study.

OBJECTIVES: The relative contributions of risk factors, as body mass index (BMI), depression, chronic diseases, smoking, and lifestyles (as physical and performance activity, social contacts and reading habit) to cognitive decline in the elderly are unclear. We explored these variables in relation to 7-year cognitive decline in long-lived Italian elderly. DESIGN: Secondary data analysis of a longitudinal study of a representative, age-stratified, population sample. SETTING: The TREVISO LONGEVA (TRELONG) Study, in Treviso, Italy. PARTICIPANTS: 120 men and 189 women, age 77 years and older (mean age 80.2 ± 6.9 years) survivors after seven years of follow up. MEASUREMENTS: Cognitive decline measured as difference between Mini-Mental State Examination (MMSE) score in 2003 and in 2010; Body mass index (BMI), handgrip, Short Physical Performance Battery (SPPB) score, social contacts, reading habit, sight, hearing, schooling, mediterranean diet and multiple clinical and survey data recorded at baseline in 2003. RESULTS: In separate univariate analyses, age, SPPB score < 5, depressive symptoms (GDS) and more comorbidities (CCI) were associated with greater cognitive decline. Otherwise higher BMI, higher handgrip, reading habit, non-deteriorated sight and hearing, and schooling were protective. In a final multivariate model, age and higher BMI were associated with greater cognitive decline while reading habits was protective. SPPB score < 5 tends, though weakly, to be associated with greater cognitive decline. These associations remained with multivariate adjustment for gender, schooling, Charlson co-morbidity index (CCI) and baseline MMSE. CONCLUSION: Age and higher baseline BMI, independent of gender, and other confounding factors, are risk factors for cognitive decline. Reading habit plays a protective role seven years later among northern Italian adults aged 70 years or older. Low physical performance tends, though weakly, to be associated with greater cognitive decline.
