Complications during Veno-Venous Extracorporeal Membrane Oxygenation in COVID-19 and Non-COVID-19 Patients with Acute Respiratory Distress Syndrome. J Clin Med 2024; 13:2871. [PMID: 38792413 PMCID: PMC11122218 DOI: 10.3390/jcm13102871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Revised: 04/30/2024] [Accepted: 05/11/2024] [Indexed: 05/26/2024] Open
Abstract
Background: Acute respiratory distress syndrome (ARDS) presents a significant challenge in critical care settings, characterized by compromised gas exchange, necessitating in the most severe cases interventions such as veno-venous extracorporeal membrane oxygenation (vv-ECMO) when conventional therapies fail. Critically ill ARDS patients on vv-ECMO may experience several complications. Limited data exist comparing complication rates between COVID-19 and non-COVID-19 ARDS patients undergoing vv-ECMO. This retrospective observational study aimed to assess and compare complications in these patient cohorts. Methods: We retrospectively analyzed the medical records of all patients receiving vv-ECMO for ARDS between March 2020 and March 2022. We recorded the baseline characteristics, the disease course and complication (barotrauma, bleeding, thrombosis) before and after ECMO cannulation, and clinical outcomes (mechanical ventilation and ECMO duration, intensive care unit, and hospital lengths of stay and mortalities). Data were compared between COVID-19 and non-COVID-19 patients. In addition, we compared survived and deceased patients. Results: Sixty-four patients were included. COVID-19 patients (n = 25) showed higher rates of pneumothorax (28% vs. 8%, p = 0.039) with subcutaneous emphysema (24% vs. 5%, p = 0.048) and longer non-invasive ventilation duration before vv-ECMO cannulation (2 [1; 4] vs. 0 [0; 1] days, p = <0.001), compared to non-COVID-19 patients (n = 39). However, complication rates and clinical outcomes post-vv-ECMO were similar between groups. Survival analysis revealed no significant differences in pre-vv-ECMO complications, but non-surviving patients had a trend toward higher complication rates and more pleural effusions post-vv-ECMO. Conclusions: COVID-19 patients on vv-ECMO exhibit higher pneumothorax rates with subcutaneous emphysema pre-cannulation; post-cannulation complications are comparable to non-COVID-19 patients.

Assessment of cephalometric parameters and correlation with the severity of the obstructive sleep apnea syndrome. J Transl Med 2024; 22:377. [PMID: 38649914 PMCID: PMC11036665 DOI: 10.1186/s12967-024-05194-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Accepted: 04/11/2024] [Indexed: 04/25/2024] Open
Abstract
BACKGROUND In individuals diagnosed with obstructive sleep apnea syndrome (OSAS), variations in craniofacial structure have been inconsistently documented, showing differing degrees of alteration between obese and nonobese patients. In addition, sleep disturbance has also been shown to induce disequilibrium in this population of patients. This pilot observational study aimed to assess craniofacial values in obese and nonobese subpopulations of patients with OSAS and their correlation and association with the severity of OSAS. We also assessed whether OSAS patients are characterized by an impaired equilibrium in relation to and associated with the severity of OSAS. METHODS We included all consecutive adult patients with OSAS. Through cephalometry, we assessed the upper (UPa-UPp) and lower (LPa-LPp) pharynx diameters, superior anterior facial height (Sor-ANS), anterior facial height (ANS-Me), anterior vertical dimension (Sor-Me), posterior facial height (S-Go) and craniovertebral angle (CVA). Furthermore, we analyzed postural equilibrium through a stabilometric examination. RESULTS Forty consecutive OSAS patients (45% female with a mean age of 56 ± 8.2 years) were included. The subgroup of nonobese patients had a reduced UPa-UPp (p = 0.02). Cephalometric measurements were correlated with the severity of OSAS in nonobese patients, whereas only Sor-ANS was correlated with the severity of OSAS in the obese subpopulation. In the overall population, altered craniofacial values are associated with severe OSAS. Although there are differences in equilibrium between obese and nonobese OSAS patients, the stabilometric measurements were not correlated or associated with OSAS severity. CONCLUSION Altered craniofacial values and compromised equilibrium in OSAS patients are linked to OSAS severity. Therefore, the management of OSAS should be tailored not only to weight management but also to craniofacial and postural rehabilitation to enhance patient outcomes.

Comparing Perioperative Complications of Off-Clamp versus On-Clamp Partial Nephrectomy for Renal Cancer Using a Novel Energy Balancing Weights Method. Life (Basel) 2024; 14:442. [PMID: 38672713 PMCID: PMC11050879 DOI: 10.3390/life14040442] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 03/24/2024] [Accepted: 03/25/2024] [Indexed: 04/28/2024] Open
Abstract
Partial nephrectomy (PN) is the primary surgical method for renal tumor treatment, typically involving clamping the renal artery during tumor removal, leading to warm ischemia and potential renal function impairment. Off-clamp approaches have been explored to mitigate organ damage, yet few results have emerged about the possible effects on hemoglobin loss. Most evidence comes from retrospective studies using propensity score matching, known to be sensitive to PS model misspecification. The energy balancing weights (EBW) method offers an alternative method to address bias by focusing on balancing all the characteristics of covariate distribution. We aimed to compare on- vs. off-clamp techniques in PN using EB-weighted retrospective patient data. Out of 333 consecutive PNs (275/58 on/off-clamp ratio), the EBW method achieved balanced variables, notably tumor anatomy and staging. No significant differences were observed in the operative endpoints between on- and off-clamp techniques, although off-clamp PNs showed slight reductions in hemoglobin loss and renal function decline, albeit with slightly higher perioperative blood loss. Our findings support previous evidence, indicating comparable surgical outcomes between standard and off-clamp procedures, with the EBW method proving effective in balancing baseline variables in observational studies comparing interventions.

Abstract
Thrombotic thrombocytopenic purpura (TTP) is a rare and life-threatening disease for which pregnancy and the postpartum period represent risk factors. Here, we present the case of a 39-year-old woman at the 31st week of gestation, who presented with cutaneous haemorrhagic symptoms. The complete blood count showed anaemia, thrombocytopenia, increase in haemolysis indices and undetectable ADAMTS13 activity. Acquired TTP was diagnosed, and she started daily plasma exchange (PEX) and methylprednisolone. After 5 days, an emergency caesarean section was performed with success because of pathologic cardiotocographic findings. After 7 days of PEX, the patient showed an initial laboratoristic improvement; unfortunately, 3 days later, she had a recurrence of disease and started daily PEX, caplacizumab and steroid, obtaining a haematological improvement. No literature data about caplacizumab use in pregnant or breastfeeding patients are available. In the present study, we describe that caplacizumab in the postpartum period could be well tolerated and effective.

Predictors of trainees’ proficiency during the learning curve of robot-assisted radical prostatectomy at high-volume institutions: results from a multicentric series. Cent European J Urol 2023; 76:38-43. [PMID: 37064261 PMCID: PMC10091888 DOI: 10.5173/ceju.2023.260] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 01/31/2023] [Accepted: 02/01/2023] [Indexed: 03/08/2023] Open
Abstract
Introduction The aim of this series was to evaluate predictors of Proficiency score (PS) achievement on a multicentric series of robot-assisted radical prostatectomies (RARP) performed by trainee surgeons with two different surgical techniques at four tertiary-care centers. Material and methods Four institutional datasets were merged and queried for RARPs performed by surgeons during their learning curve (LC) between 2010 and 2020 using two different approaches (Group A, Retzius-sparing RARP, n = 164; Group B, standard anterograde RARP, n = 79). Logistic regression analysis was performed to identify predictors of PS achievement for the overall trainee cohort. For all analyses, a two-sided p <0.05 was considered significant. Results Group B showed significantly increased median operative time, positive surgical margins (PSM) status, increased number of nerve-sparing procedures, shorter LC time (each p <0.04). PS, continence status, potency, biochemical recurrence and 1-year trifecta rates were comparable between groups (each p >0.3). On multivariable analysis, time from LC starting ≥12 months (OR = 2.79; 95%IC [1.15-6.76]; p = 0.02) and a nerve-sparing intent (OR = 3.18; 95%IC [1.15-8.77]; p = 0.02) were independent predictors of PS score achievement (Table 3). Conclusions Higher PS rates for RARP trainees may be expected after 12 months from LC beginning. Short-term training courses are unlikely to confer proper surgical training, while long-term structured training programs seem to be beneficial on perioperative outcomes.

Abstract
OBJECTIVE To evaluate the impact on erectile and ejaculatory function following transrectal ultrasound-guided biopsies of the prostate (TRUS-Bx) in sexually active men. METHODS Monocentric prospective study from May 2021 to January 2022 of consecutive patients with suspected prostate cancer [elevated prostate specific antigen (PSA) level and/or abnormal digital rectal examination] undergoing TRUS-Bx. The 15-item version of the International Index of Erectile Function (IIEF-15), Premature Ejaculation Diagnostic Tool (PDET) and short form of Male Sexual Health Questionnaire (MSHQ-EjD Short Form) were assessed before, one and three months after TRUS-Bx. The primary endpoint was to evaluate the risk of temporary post-biopsy erectile and/or ejaculatory dysfunctions. The statistical significance was set as p value < 0.05. RESULTS A total of 276 consecutive patients were included in the study. The median age, PSA and biopsy cores were 65 years (IQR 59-69), 7 ng/ml (IQR 5-9.7) and 16 (IQR 12-16), respectively. We compared the IIEF subdomains before TRUS-Bx vs. one or three months: the erectile function (EF) decreased after one month (p<0.001) but recovered after three months (p=0.833); the Orgasmic Function (OF), the Sexual Desire (SD), the Intercourse Satisfaction (IS), the Overall Satisfaction (OS), and Total IIEF decreased significantly after both one and three months compared to pre-biopsy values (p < 0.05). As for ejaculatory function (EjF), PDET, MSHQ-EjD Short Form 1, 2, 3 and MSHQ-EjD Short Form 4 scores decreased significantly after one month (p < 0.001), but they returned to pre-biopsy values after 3 months: p = 0.538, p = 0.071 and p = 0.098, respectively. CONCLUSIONS Our study proved that EF, assessed through IIEF- 15, and ejaculatory function, assessed through PDET and MSHQ-EjD Short Form, were negatively affected by TRUS-Bx one month after the procedure and recovered after three months. Interestingly, the other IIEF-15 subdomains (OF, SD, IS, OS and Total) resulted as significantly reduced also after 3 months: this issue highlights the importance of carefully considering the indication to TRUS-Bx.

Could we safely omit a Repeat Transurethral Resection of the Bladder (re-TURB) after Hexaminolevulinate Photodynamic Diagnostics (PDD)-TURB? Arch Ital Urol Androl 2022; 94:424-427.

Abstract
OBJECTIVE Bladder cancer (BC) is considered one of the malignancies with moderate-high incidence, high rate of recurrence and costly management. Diagnosis and staging are thus important for therapeutic purposes. Considering the risk of residual tumour and understaging, in specific cases, international guidelines recommend performing a second transurethral resection of the bladder (reTURB). Our study aimed to evaluate the impact of hexaminolevulinate Photodynamic Diagnostics (PDD) at first TURB on the rate of residual tumour. MATERIALS AND METHODS We retrospectively analysed patients undergoing TURB in our centre between 2012 and 2020. Eightytwo patients had a re-TURB after a first complete TURB with a delay < 3 months. Patients who had an incomplete first resection were excluded. We compared patients who underwent standard white light cystoscopy/TURB and then hexaminolevulinate PDDguided reTURB (group A, n = 49) and patients with PDD-cystoscopy/ TURB at the first procedure then white light cystoscopy/reTURB (group B, n = 33). The residual tumour rate at reTURB as well as median recurrence-free survival (RFS) were compared between the two groups. RESULTS Residual tumour at reTURB was detected in 48.8% of cases in our cohort, with a significant difference between the two groups (71.4% in group A versus 12.5% in group B, p < 0.001). After a median follow-up of 22 months, the median RFS was 15 months in Group A and 32 months in Group B, but this difference was not significant (p = 0.7). CONCLUSIONS Using PDD at the time of the initial TURB had a statistically significant impact on the rate of residual tumour at the reTURB. Nevertheless, the percentage of residual tumour even with the use of PDD does not allow for safely omitting second resection. Performing a reTURB with PDD for patients who did not have it initially, provides the same benefit in terms of recurrence-free survival.

Abstract
Objectives To evaluate the impact of quarantine in SARS-CoV-2 infected patients on sexual functions (SF) and consequences regarding post-infection sexuality. Methods We performed a monocentric longitudinal study of sexually active patients, from May 2020 to October 2020, with SARS-CoV-2 infection confirmed with a nasopharyngeal reverse transcriptase polymerase chain reaction (RT-PCR). The study was conducted via email by a single urologist. Baseline characteristics were recorded. The study period was divided in 4 subperiods: before getting tested (T1), during quarantine (T2), 1 month after negative test (T3) and 3 months after negative test (T4). All participants were invited to complete these questionnaires: Sexual Distress Schedule (SDS), International Index of Erectile Function Questionnaire (IIE-F) and two internal made questionnaires of 10 and 6-items. The primary endpoint was to evaluate the impact of quarantine on SF during and after the SARS-CoV-2 infection. Results A total of 22 male patients met the inclusion criteria. The median age was 63 (IQR: 58.2-67.0) years and the median Charlson score was 3 (IQR 1–4). Of all, 9 (40.9%) patients were admitted in the Intensive Care Unit (ICU) with a median length of stay (LOS) of 10 days (IQR: 8-13). The differences for both SDS/IIEF scores, between T1-T2 and T2-T3, were statistically significant (p<0.001) and the mean number of SF decreased significantly during T2 and returned to normal in T4. In 20 patients (90.9%), SARS-CoV-2 had a huge impact on relationship and sexual life, but no patient attended a clinic for sexual difficulties. Conclusions Quarantine have negatively influenced SF in infected patients, but 3 months after the RT-PCR negative test, a promising return to the pre-infection SF values is observed. Further studies are needed to evaluate long-term sexual outcome in SARS-CoV-2 infected patients. Conflicts of Interest The authors reported no conflict of interest.

Abstract
Human gut microbiome is related to different clinical conditions and diseases. Recently several hypotheses have been theorized about a link between gut microbiota and genitourinary disease including urinary tract infections, and benign prostatic hyperplasia. Despite several data, underlying mechanisms still remain unclear. The aim of this review is to report the current state of knowledge in relation to urinary tract infections, benign prostatic hyperplasia and intestinal microbiota with a focus on its role in the development of disease and the underlying pathophysiologic mechanisms.

Abstract
Abstract
Background
Glioblastoma (GB) is the most severe form of brain cancer, with a 12-15 month median survival. Although cell therapies for GB are on the near horizon, surgical resection, temozolomide (TMZ) and radiotherapy (RT) remain the primary therapeutic options for GB, and no new small-molecule therapies have been introduced in recent years. This therapeutic standstill is partially because preclinical models of GB do not reflect the complexities of GB cell biology. Furthermore, the aggressive progression of GB makes it critical to identify patient-tailored therapeutic strategies early.
Material and Methods
We developed a novel in-vitro 3D glioblastoma explants (GB-EXPs) model derived from patients’ resected tumors maintaining cytoarchitecture seen in the tumors. We then performed metabolic-imaging by fluorescence lifetime imaging microscopy (FLIM) on live GB-EXPs to predict drug response, using TMZ as test drug.
Results
The entire process was successfully completed within 1 week since surgery. A unique drug response sample stratification emerged that was well reflected at the molecular level, highlighting new targets associated with TMZ treatment and identifying a molecular signature associated with survival.
Conclusion
To the best of our knowledge, this is the first time that FLIM-based metabolic imaging is used on live glioblastoma explants to test anti-neoplastic drugs. FLIM-based readouts of drug response in GB explants could accelerate precision treatment of patients with GB and the identification of new anti-GB drugs.

Abstract
Abstract
Background
Circulating Tumor Cells (CTCs) are considered to be one of the important causes of tumor recurrence and distant metastasis. For many years, glioblastoma (GB) was thought to be restricted to the brain. Nevertheless, a growing body of evidence indicates that, like many other cancers, hematogenic dissemination is a reality. The absence of a procedural uniformity in literature prompted us to develop an innovative and sensitive method to obtain CTCs in GB. Our aim is to define the genetic background of single CTCs compared with the primary GB tumor and its recurrence to assess whether or not their presence in the peripheral circulation correlates with GB migration and dissemination.
Material and Methods
CTCs were enriched from whole blood of one patient with recurrent GB with Parsortix Cell Separation System and analysed on DEPArray system. After that, CTCs Copy Number Aberrations (CNAs) and sequencing analysis was performed to compare CTCs genetic background with the same patient’s primary and recurrence tissues, analysed by NextSeq 500 (whole exome sequencing).
Results
We obtained 211 mutations in common between primary and recurrence tumor. Among these, three somatic mutations (c.430 G>A in PRKCB gene, c.815 C>T in TBX1 gene and c.1554 T>G in COG5 gene) were selected to investigate their presence in recurrence CTCs. Almost all of the sorted CTCs (9/13) had at least one of the mutations tested.
Conclusion
In confirmation of the hypothesis, the CTCs detected in the patient's blood were actually cancer cells deriving from GB tumor.

Abstract
Background Aim of the study was to enrol a group of individuals with schizophrenia in a long-term moderate-intensity physical activity program and to evaluate its effects on their cognitive functions and cardiovascular risk factors. An additional aim of the study was the comparison of the adherence to the physical activity program before and during the COVID-19 pandemic. Methods Forty sedentary patients diagnosed with schizophrenia (mean age 46.4 ± 9.6) followed by the Public Mental Health Department of Ferrara were included in the study. 28 of them followed a 1-year walking program consisting of two guided walking sessions/week, while 12 maintained their sedentary lifestyle and followed the usual Cognitive Rehabilitation program. To the participants following the walking program VO2 peak and walking speed were assessed at baseline and at the end of the program. All participants were evaluated on blood pressure and anthropometric variable. Cognitive functions were assessed with the Screen for Cognitive Impairment in Psychiatry (SCIP) and with the Frontal Assessment Battery (FAB) questionnaires. Results The 20 participants completing the walking program displayed significant improvements in cognitive functions (dppc2 0.35 for SCIP and 0.26 for FAB), with a positive correlation between SCIP score and the number of sessions attended (R = 0.86, p < 0.001), evident in the patients attending to at least 75 of the 100 walking sessions. Walking speed and VO2peak increased significantly and a decrease of body weight, BMI, systolic and diastolic blood pressure was also observed. The adherence to the walking program registered during Covid-19 period did not differ from that observed before the pandemic. The 12 CG (Control Group) patients maintaining the sedentary lifestyle did not display improvements of cognitive functions. Conclusions The main finding of this study is the improvement of cognitive functions which is significantly related to the number of walking sessions attended by participants with schizophrenia. The walking program, guided by exercise specialists, proved to be an enjoyable activity for people with mental disorder feasible even during the COVID-19 pandemic. Trial registration Retrospectively registered on ISRCTN as non-randomized trial (n. ISRCTN14763786).

Abstract
OBJECTIVES To assess the long-term clinical outcomes and identify factors predicting success of endoscopic treatment for symptomatic vesicoureteral reflux (VUR) after kidney transplantation. PATIENTS AND METHODS A retrospective chart review of all patients who had a symptomatic VUR after renal transplantation at our centre between January 2000 and December 2020 was performed. VUR was documented by retrograde cystography and was determined by at least one episode of acute graft pyelonephritis (AGPN). Endoscopic injections of polydimethylsiloxane (MacroPlastique™) or dextranomer/hyaluronic acid copolymer (Deflux™) were performed by expert urologists via rigid cystoscopy with a bevelled needle system. The results of endoscopic treatment were evaluated by cystography at three months. The primary endpoint was clinical efficacy as defined by the absence of AGPN during follow-up. Radiological success was defined by the absence of VUR at the three months follow-up cystography. RESULTS Out of 2135 kidney transplantations, a total of 117 (5.5%) patients had symptomatic VUR: 100 (85.5%) underwent Deflux™ and 17 (14.5%) MacroPlastique™. Preoperative high-grade VUR was recorded in 71% of patients. One postoperative complication was observed, Clavien > II. After a median follow-up of 11.2 years (IQR 6.5-14.4), clinical success was achieved in 73 patients (62.4%). Radiological success was obtained in 42 patients (36%). Multivariable analysis failed to identify predictors of endoscopic treatment success, which was independent of the preoperative grade of VUR and the type of bulking agent used. CONCLUSION Endoscopic treatment of VUR is a simple and well-tolerated procedure with long-term clinical efficacy.

Objective Coronavirus disease 2019 (COVID-19) outbreak has correlated with the disruption of screening activities and diagnostic assessments. Endometrial cancer (EC) is one of the most common gynecological malignancies and it is often detected at an early stage, because it frequently produces symptoms. Here, we aim to investigate the impact of COVID-19 outbreak on patterns of presentation and treatment of EC patients. Methods This is a retrospective study involving 54 centers in Italy. We evaluated patterns of presentation and treatment of EC patients before (period 1: March 1, 2019 to February 29, 2020) and during (period 2: April 1, 2020 to March 31, 2021) the COVID-19 outbreak. Results Medical records of 5,164 EC patients have been retrieved: 2,718 and 2,446 women treated in period 1 and period 2, respectively. Surgery was the mainstay of treatment in both periods (p=0.356). Nodal assessment was omitted in 689 (27.3%) and 484 (21.2%) patients treated in period 1 and 2, respectively (p<0.001). While, the prevalence of patients undergoing sentinel node mapping (with or without backup lymphadenectomy) has increased during the COVID-19 pandemic (46.7% in period 1 vs. 52.8% in period 2; p<0.001). Overall, 1,280 (50.4%) and 1,021 (44.7%) patients had no adjuvant therapy in period 1 and 2, respectively (p<0.001). Adjuvant therapy use has increased during COVID-19 pandemic (p<0.001). Conclusion Our data suggest that the COVID-19 pandemic had a significant impact on the characteristics and patterns of care of EC patients. These findings highlight the need to implement healthcare services during the pandemic. The prevalence of patients with early-stage endometrial cancer (EC) has been lower during coronavirus disease 2019 (COVID-19) pandemic than before its onset. Further evidence is needed to assess the impact of COVID-19 pandemic on survival outcomes of EC patients.

Gait risk factors for disease progression differ between non-traumatic and post-traumatic knee osteoarthritis. Osteoarthritis Cartilage 2021; 29:1487-1497. [PMID: 34348184 DOI: 10.1016/j.joca.2021.07.014] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 06/18/2021] [Accepted: 07/24/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To examine if relationships between knee osteoarthritis (OA) progression with knee moments and muscle activation during gait vary between patients with non-traumatic and post-traumatic knee OA. DESIGN This longitudinal study included participants with non-traumatic (n = 17) and post-traumatic (n = 18) knee OA; the latter group had a previous anterior cruciate ligament rupture. Motion capture cameras, force plates, and surface electromyography measured knee moments and lower extremity muscle activation during gait. Cartilage volume change were determined over 2 years using magnetic resonance imaging in four regions: medial and lateral plateau and condyle. Linear regression analysis examined relationships between cartilage change with gait metrics (moments, muscle activation), group, and their interaction. RESULTS Measures from knee adduction and rotation moments were related to lateral condyle cartilage loss in both groups, and knee adduction moment to lateral plateau cartilage loss in the non-traumatic group only [β = -1.336, 95% confidence intervals (CI) = -2.653 to -0.019]. Generally, lower levels of stance phase muscle activation were related to greater cartilage loss. The relationship between cartilage loss in some regions with muscle activation characteristics varied between non-traumatic and post-traumatic groups including for: lateral hamstring (lateral condyle β = 0.128, 95%CI = 0.003 to 0.253; medial plateau β = 0.199, 95%CI = 0.059 to 0.339), rectus femoris (medial condyle β = -0.267, 95%CI = -0.460 to -0.073), and medial hamstrings (medial plateau; β = -0.146, 95%CI = -0.244 to -0.048). CONCLUSION Findings indicate that gait risk factors for OA progression may vary between patients with non-traumatic and post-traumatic knee OA. These OA subtypes should be considered in studies that investigate gait metrics as risk factors for OA progression.

Abstract
Background Gestational diabetes mellitus (GDM) incidence is increasing worldwide. It represents a major risk factor for adverse foetal-maternal outcomes. Awareness among women in regard to GDM-related risks (in particular foetus ones) has been proven to have an impact on compliance with recommendations. Therefore we aimed to evaluate the efficacy of our post-diagnosis counselling, that informs affected women of the GDM related risks for complications, in determining an adequate level of understanding. Method This is a cohort study involving 400 women undergoing the 24-28 weeks 75 g oral glucose tolerance test. Two hundred women diagnosed with GDM received the post-diagnosis counselling (treatment group) and two hundred women diagnosed without did not receive any counselling (control group). Both populations were surveyed with a 5 question questionnaire regarding their awareness about GDM foetal-maternal related risks. Their level of education about GDM foetal-maternal related risks, estimated according to the number of correct answers, was scored as: primary (score 0-1), secondary (score 2-3) or tertiary (score 4-5). Results Most of the women in the treatment group after receiving the post-diagnosis counselling have demonstrated a secondary level of education 132/200 (66%). Their mean level of awareness was higher in comparison to the control group 2.6 ± 1.8 (SD) versus 2.14 ± 1.8 (SD) p value = 0.012. In particular, they’ve demonstrated to be more aware of the risks for the foetus to become macrosomic (p = 0.004) or to die in utero (p = 0.0001). A high level of education and to have had previous pregnancies positively affected correct answers. Conclusions Our post-diagnosis counselling has played a role in improving women awareness about GDM foetal-maternal related risks. Future study will explore the impact of women’s level of awareness on glycaemic control.

Abstract
Primary immune thrombocytopenia (ITP) is an autoimmune disorder characterized by isolated thrombocytopenia (platelet count <100 × 109/l) in the absence of other causes or disorders associated. The incidence of ITP in pregnancy is one to two cases per 1000 gestations. ITP could be diagnosed before or during pregnancy; sometimes a relapse of a previously diagnosed ITP can occur. Intravenous immune globulins (IVIg) and corticosteroids are the standard frontline therapy because of their well known safety profile either for the mother or for the neonate. Treatments for refractory patients are limited by potential fetal risk. We report the case of a patient with ITP along pregnancy, refractory to corticosteroids and IVIg, successfully treated with, the thrombopoietin receptor agonist (TPO-RA) eltrombopag. Patient received this compound for almost the whole pregnancy and in particular for the whole first trimester, without any complication for the mother and the neonate. Although transient administration of TPO-RAs in pregnancy seems to be well tolerated, their use during the whole gestation is still controversial; this is the reason of the description of this case, which did not show any complications, and thus it could add useful information on this field.

P-240 Human extracellular vesicles (EVs) secreted by aneuploid embryos potentiate development of non-invasive PGT-A RNA biomarkers and stimulate MUC1 up-regulation in primary endometrial stromal cells (ESCs).

Abstract
Abstract
Study question
Could EVs secreted by aneuploid embryos a) serve for development of RNA biomarkers for PGT-A and b) elicit a relevant transcriptomic response in decidualised ESCs?
Summary answer
Aneuploid embryo EVs a) contain PPM1J, LINC00561, ANKRD34C and TMED10 in differential abundance from euploid EVs and b) induce up-regulation of MUC1 in decidualised ESCs.
What is known already
Embryo aneuploidy accounts for approximately 50% of all recurrent implantation failures in women >35 years old. PGT-A identifies euploid embryos to increase implantation probability but the technology is controversial as it requires an invasive embryo biopsy with an elusive long-term biosafety. The development of non-invasive methods to screen out aneuploid embryos is paramount. It is also critical to decode the embryo-endometrial dialog underlying implantation failure. We have previously reported that IVF embryos secrete EVs that can be internalised by ESCs, conceptualising that successful implantation to the endometrium is facilitated by EVs, which may additionally serve as biomarkers of ploidy status.
Study design, size, duration
Embryos destined for biopsy on days 5-7 for PGT-A were grown under standard conditions. Spent media (30μl) were collected from euploid (n = 175) and aneuploid embryos (n = 145) at both cleavage (days 1-3) and blastocyst (days 3-5) stage. Media samples from n = 35 cleavage embryos were pooled in order to obtain five euploid and four aneuploidy pools. Blastocyst media were pooled to create one euploid and one aneuploid pool. ESCs were obtained from five women undergoing diagnostic laparoscopy.
Participants/materials, setting, methods
The study was realised at a research hospital. EVs were isolated from euploid and aneuploid Day3 pools with differential ultracentrifugation and EV-RNA sequencing was performed following the SMARTer Stranded Total RNA-Seq approach. ESCs were decidualised (E2:10nM, P4:1uM, cAMP:0.5 mM twice every 48 hours) and treated for 24 hours with 50 ng/ml euploid or aneuploid EVs extracted from blastocyst media. RNA sequencing was performed on ESCs following the Truseq RNAseq protocol.
Main results and the role of chance
Aneuploid cleavage stage embryos (n = 4) secreted EVs that were less abundant in RNA fragments originating from the genes PPM1J (log2fc=-5.13, p = 0.011), LINC00561 (log2fc=-7.87, p = 0.010) and ANKRD34C (log2fc=-7.30, p = 0.017) and more abundant in TMED10 (log2fc=1.63 p = 0.025) compared to EVs (n = 5) from euploid embryos. Decidualisation per se induced downregulation of MUC1 (log2FC=-0.54, p = 0.0028) in ESCs as prerequisite for the establishment of receptive endometrium. The expression of MUC1 transcript in decidualised ESCs was significantly increased following treatment with aneuploid compared to euploid embryo-secreted EVs (log2FC=0.85, p = 0.0201).
Limitations, reasons for caution
The findings of the study may require validation utilising a second cohort of EVs samples.
Wider implications of the findings
This discovery that the RNA cargo of EVs secreted from aneuploid cleavage stage embryos is diverse from that of euploid embryos potentiates the development of non-invasive methodology for PGT-A. The upregulation of MUC1 in decidualised ESCs following aneuploid embryo EV treatment proposes a new mechanism underlying implantation failure.

Abstract
PURPOSE To report long-term oncological outcomes after penile-sparing surgery (PSS) for superficial (Ta-Tis) or initially invasive (T1) penile cancer patients. METHODS We retrospectively analysed 85 patients with Ta/Tis/T1cN0cM0 penile cancer (1996-2018). All patients underwent PSS: circumcision, excision or laser ablation. First, Kaplan-Meier plots and multivariable Cox regression models tested tumor recurrence rates (any local/regional/metastatic). Second, Kaplan-Meier plots depicted progression-free survival (≥T2 or N1-3 or M1 disease). RESULTS Median (IQR) follow-up time was 64 (48-95) months. Overall, 48 (56%) patients experienced tumor recurrence. Median (IQR) time to tumor recurrence was 34 (7-52) months. Higher recurrence rates were observed for Tis (65%) and T1 (64%), compared to Ta (40%), but these differences were not significant on multivariable Cox regression analyses (HR:2.0 with 95% CI [0.9-5.1] and HR:2.2 with 95% CI [0.9-5.9], respectively). Moreover, higher recurrence rates were observed for G2-3 tumors (74%), compared to G1 (57%), but these differences were not significant on multivariable Cox regression analyses (HR:1.6; 95% CI [0.8-3.2]). During follow-up, 15 (17.5%) vs. 18 (21.2%) vs. 10 (11.5%) patients underwent 1 vs. 2 vs. ≥3 PSS. Moreover, 26 (30.6%) and 4 (4.7%) men were treated with glansectomy and partial/total penile amputation due to local progression, tumor size or patient preference. Additionally, 24 (28%) men underwent invasive nodal staging. Last, 22 (25.9%) patients experienced disease progression. Median (IQR) time to disease progression was 51 (31-82) months. CONCLUSION Patients treated with PSS for newly diagnosed superficial or initially invasive squamous cell carcinoma of the penis should be informed about the non-negligible risk of tumor recurrence and disease progression over time. In consequence, strict follow-up protocols are needed.

Increased Body Mass Index Is a Risk Factor for Poor Clinical Outcomes after Radical Prostatectomy in Men with International Society of Urological Pathology Grade Group 1 Prostate Cancer Diagnosed with Systematic Biopsies. Urol Int 2021; 106:75-82.

Abstract
INTRODUCTION The association between obesity and clinically significant prostate cancer (PCa) is still a matter of debate. In this study, we evaluated the effect of body mass index (BMI) on the prediction of pathological unfavorable disease (UD), positive surgical margins (PSMs), and biochemical recurrence (BCR) in patients with clinically localized (≤cT2c) International Society of Urological Pathology (ISUP) grade group 1 PCa at biopsy. METHODS 427 patients with ISUP grade group 1 PCa who have undergone radical prostatectomy and BMI evaluation were included. The outcome of interest was the presence of UD (defined as ISUP grade group ≥3 and pT ≥3a), PSM, and BCR. RESULTS Statistically significant differences resulted in comparing BMI with prostate-specific antigen (PSA) and serum testosterone levels (both p < 0.0001). Patients with UD and PSM had higher BMI values (p < 0.0001 and p = 0.006, respectively). BCR-free survival was significantly decreased in patients with higher BMI values (p < 0.0001). BMI was an independent risk factor for BCR and PSM. Receiver-operating characteristic analysis testing PSA accuracy in different BMI groups, showed that PSA had a reduced predictive value (area under the curve [AUC] = 0.535; 95% confidence interval [CI] = 0.422-0.646), in obese men compared to overweight (AUC = 0.664; 95% CI = 0.598-0.725) and normal weight patients (AUC = 0.721; 95% CI = 0.660-0.777). CONCLUSION Our findings show that increased BMI is a significant predictor of UD and PSM at RP in patients with preoperative low-to intermediate-risk diseases, suggesting that BMI evaluation may be useful in a clinical setting to identify patients with favorable preoperative disease characteristics harboring high-risk PCa.

Abstract
OBJECTIVES To compare the detection rate of BCG refractory tumors between white light cystoscopy (WL-C) and Photodynamic Diagnosis cystoscopy (PDD-C). METHODS We performed a monocentric retrospective study that included all consecutive patients with high-risk non-muscle-invasive bladder cancer (NMIBC) diagnosed from January 2017 to January 2021. All patients had an initial Transurethral resection of bladder tumor (TURBT) with PDD ± restaging TURBT if needed, followed by full-dose BCG induction. Within 8 weeks following BCG induction all patients had both WL-C and PDD-C under general anesthesia ± TURBT in case of suspicious lesion. The primary endpoint was the detection of bladder cancer (BC) at post-BCG cystoscopy. RESULTS A total of 136 consecutive patients met inclusion criteria. Initial BC characteristics were: 35.6% of T1 tumor, 92.6% high-grade and 48.6% associated cis. BC was diagnosed in 33/136 cases (24%) at early PDD-C after BCG induction: 77% Ta, 23% T1, 56% associated cis, 68% high grade and 6% MIBC. Sensibility and Specificity of WL-C and PDD-C: 41 vs 91% (p<0.001) and 86 vs 75% (p=0.001). PDD-C detected 16 additional tumors: 81.3% Ta, 18.7% T1, 75% associated cis and 75% high grade. CONCLUSIONS Systematic use of PDD after BCG induction increased the detection of BCG-refractory tumors and lead to significant modification in the treatment of high-risk NMIBC. Future studies are needed to evaluate long-term oncological benefit of early PDD reevaluation and its cost-effectiveness.

Abstract
Vesicouterine fistula (VUF) is a rare extra-anatomical communication developing between the uterus or cervix and the urinary bladder, most commonly after an iatrogenic injury during a cesarean section. Patients with VUF may have various clinical presentations, ranging from Youssef's syndrome (vaginal urine leakage, amenorrhea, and menouria) to urinary tract infection and infertility. Quality of life for patients having this pathology is strongly affected owing to the psychological burden. Treatment is surgery based because low success rates have been reported for conservative or minimally invasive approaches. Herein, we present a case of a 35-year-old woman successfully treated by a minimally invasive endoscopic repair procedure with the injection of microfragmented autologous adipose tissue (Lipogems®).

Abstract
BACKGROUND The Double-J stent is one of the most commonly used devices in urologic practice. Due to its widespread use, numerous common complications have been reported, such as irritative symptoms, infection, and encrustation. More rare complications have also been described, such as up or downward migration and displacement outside the urinary tract. We present a rare case of downward migration of a Double-J stent in a 21-year-old Caucasian female. CASE PRESENTATION A 21-year-old female with a solitary kidney presented to the emergency department with acute renal failure, left flank pain, and fever. She had undergone left Double-J stenting 1 week earlier in her homeland for left renal colic and anuria. A kidney-ureter-bladder X-ray revealed a 10-mm lumbar ureteral stone and the proximal coil of the Double-J stent making multiple loops along the ureter, resulting in a helical appearance. She underwent surgery to remove the previous stent and to place a new one. She was discharged 2 days later and her renal function had returned to normal values at her 1-week follow-up. CONCLUSIONS Double-J Stent placement is a common procedure in the management of urinary tract diseases but is not devoid of life-threatening complications. Regular follow-up of stents and on-time evaluation of clinical complaints are mandatory for an aggressive treatment of complications.

A comparison of muscle activation and knee mechanics during gait between patients with non-traumatic and post-traumatic knee osteoarthritis. Osteoarthritis Cartilage 2019; 27:1033-1042. [PMID: 30898621 DOI: 10.1016/j.joca.2019.02.798] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2018] [Revised: 02/25/2019] [Accepted: 02/27/2019] [Indexed: 02/02/2023]
Abstract
OBJECTIVE The objective was to compare muscle activation and knee mechanics during gait between participants with non-traumatic knee osteoarthritis (OA), post-traumatic knee OA, and healthy adults. DESIGN Participants with non-traumatic knee OA (n = 22), post-traumatic knee OA (n = 19), and healthy adults (n = 22) completed gait trials for this observational, cross-sectional study. Post-traumatic OA group had a history of traumatic anterior cruciate ligament (ACL) rupture. Surface electromyography (EMG) measured activation of seven lower extremity muscles. Motion capture cameras and force plates measured motion and force data. Principal component analysis (PCA) determined waveform characteristics (principal components) from EMG, knee angle, and knee external moment waveforms. Analysis of variance (ANOVA) examined group differences in principal component scores (PC-scores). Regression analyses examined if a variable that coded for OA group could predict PC-scores after accounting for disease severity, alignment, and lateral OA. RESULTS There was lower gastrocnemius EMG amplitudes (P < 0.01; ANOVA) in the post-traumatic OA group compared to healthy group. Non-traumatic OA group had higher vastus lateralis, vastus medialis, and rectus femoris EMG compared to post-traumatic OA group (P = 0.01 to 0.04) in regression analyses. Also, non-traumatic OA group had higher and prolonged lateral hamstring EMG compared to healthy (P = 0.03; ANOVA) and post-traumatic OA (P = 0.04; regression) groups respectively. The non-traumatic OA group had lower knee extension (P < 0.05) and medial rotation (P < 0.05) moments than post-traumatic and healthy groups. CONCLUSIONS Muscle activation and knee mechanics differed between participants with non-traumatic and post-traumatic knee OA and healthy adults. These OA subtypes had differences in disease characteristics that may impact disease progression.

Previsual symptoms of Xylella fastidiosa infection revealed in spectral plant-trait alterations. NATURE PLANTS 2018; 4:432-439.

Abstract
Plant pathogens cause significant losses to agricultural yields and increasingly threaten food security1, ecosystem integrity and societies in general2-5. Xylella fastidiosa is one of the most dangerous plant bacteria worldwide, causing several diseases with profound impacts on agriculture and the environment6. Primarily occurring in the Americas, its recent discovery in Asia and Europe demonstrates that X. fastidiosa's geographic range has broadened considerably, positioning it as a reemerging global threat that has caused socioeconomic and cultural damage7,8. X. fastidiosa can infect more than 350 plant species worldwide9, and early detection is critical for its eradication8. In this article, we show that changes in plant functional traits retrieved from airborne imaging spectroscopy and thermography can reveal X. fastidiosa infection in olive trees before symptoms are visible. We obtained accuracies of disease detection, confirmed by quantitative polymerase chain reaction, exceeding 80% when high-resolution fluorescence quantified by three-dimensional simulations and thermal stress indicators were coupled with photosynthetic traits sensitive to rapid pigment dynamics and degradation. Moreover, we found that the visually asymptomatic trees originally scored as affected by spectral plant-trait alterations, developed X. fastidiosa symptoms at almost double the rate of the asymptomatic trees classified as not affected by remote sensing. We demonstrate that spectral plant-trait alterations caused by X. fastidiosa infection are detectable previsually at the landscape scale, a critical requirement to help eradicate some of the most devastating plant diseases worldwide.

Abstract
With the aim of verifying the in vivo applicability of local hyperthermia combined with chemotherapy, 13 patients with superficial metastases from different histologic types of carcinoma, mostly from head and neck cancer, were entered in a pilot study. The chemotherapeutic regimen was cisplatinum, 20 mg/m2/dx5 days, bleomycin, 10 mg/m2 on days 8 and 12, methotrexate, 100 mg/m2 on day 15, followed after 24 by folinic acid. Hyperthermia, using a microwave apparatus, and chemotherapy were delivered simultaneously. Objective remissions were achieved in 54% of patients, within the hyperthermia field (1 CR and 6 PR). No serious toxicity was noted. Methotrexate distribution after local hyperthermia was evaluated in 8 patients. Response duration was not gratifying, except for patients successively treated with radiation. In conclusion, the combination of chemotherapy plus local hyperthermia deserves subsequent evaluation as part of adjunctive programs.

Abstract
Circulating endothelial cells (CEC) represent a restricted peripheral blood (PB) cell subpopulation with high potential diagnostic value in many endothelium-involving diseases. However, whereas the interest in CEC studies has grown, the standardization level of their detection has not. Here, we undertook the task to align CEC phenotypes and counts, by standardizing a novel flow cytometry approach, within a network of six laboratories. CEC were identified as alive/nucleated/CD45negative/CD34bright/CD146positive events and enumerated in 269 healthy PB samples. Standardization was demonstrated by the achievement of low inter-laboratory Coefficients of Variation (CVL), calculated on the basis of Median Fluorescence Intensity values of the most stable antigens that allowed CEC identification and count (CVL of CD34bright on CEC ~ 30%; CVL of CD45 on Lymphocytes ~ 20%). By aggregating data acquired from all sites, CEC numbers in the healthy population were captured (medianfemale = 9.31 CEC/mL; medianmale = 11.55 CEC/mL). CEC count biological variability and method specificity were finally assessed. Results, obtained on a large population of donors, demonstrate that the established procedure might be adopted as standardized method for CEC analysis in clinical and in research settings, providing a CEC physiological baseline range, useful as starting point for their clinical monitoring in endothelial dysfunctions.

Abstract
In autumn 2013, the presence of Xylella fastidiosa, a xylem-limited Gram-negative bacterium, was detected in olive stands of an area of the Ionian coast of the Salento peninsula (Apulia, southern Italy), that were severely affected by a disease denoted olive quick decline syndrome (OQDS). Studies were carried out for determining the involvement of this bacterium in the genesis of OQDS and of the leaf scorching shown by a number of naturally infected plants other than olive. Isolation in axenic culture was attempted and assays were carried out for determining its pathogenicity to olive, oleander and myrtle-leaf milkwort. The bacterium was readily detected by quantitative polymerase chain reaction (qPCR) in all diseased olive trees sampled in different and geographically separated infection foci, and culturing of 51 isolates, each from a distinct OQDS focus, was accomplished. Needle-inoculation experiments under different environmental conditions proved that the Salentinian isolate De Donno belonging to the subspecies pauca is able to multiply and systemically invade artificially inoculated hosts, reproducing symptoms observed in the field. Bacterial colonization occurred in prick-inoculated olives of all tested cultivars. However, the severity of and timing of symptoms appearance differed with the cultivar, confirming their differential reaction.

Abstract
According to the European Directive 2008/50/CE, the air quality assessment consists in the measurement of the concentration fields, and the evaluation of the mean, number of exceedances, etc. of some chemical species dangerous to human health. The measurements provided by an air quality ground-based monitoring network are the main information source but the availability of these data is often limited by several technical and operational problems. In this paper, the best linear unbiased estimator (BLUE) is proposed to validate the pollutant concentration values and to fill the gaps in the measurement of time series collected by a monitoring network. The BLUE algorithm is tested using the daily mean concentrations of particulate matter having aerodynamic diameter less than 10 μ (PM10 concentrations) measured by the air quality monitoring sensors operating in the Lazio Region in Italy. The comparison between the estimated and measured data evidences an error comparable with the measurement uncertainty. Due to its simplicity and reliability, the BLUE will be used in the routine quality test procedures of the Lazio air quality monitoring network measurements.

A Fully Automated, Atlas-Based Approach for Superior Cerebellar Peduncle Evaluation in Progressive Supranuclear Palsy Phenotypes. AJNR Am J Neuroradiol 2016; 38:523-530.

Abstract
BACKGROUND AND PURPOSE The superior cerebellar peduncle is damaged in progressive supranuclear palsy. However, alterations differ between progressive supranuclear palsy with Richardson syndrome and progressive supranuclear palsy-parkinsonism. In this study, we propose an automated tool for superior cerebellar peduncle integrity assessment and test its performance in patients with progressive supranuclear palsy with Richardson syndrome, progressive supranuclear palsy-parkinsonism, Parkinson disease, and healthy controls. MATERIALS AND METHODS Structural and diffusion MRI was performed in 21 patients with progressive supranuclear palsy with Richardson syndrome, 9 with progressive supranuclear palsy-parkinsonism, 20 with Parkinson disease, and 30 healthy subjects. In a fully automated pipeline, the left and right superior cerebellar peduncles were first identified on MR imaging by using a tractography-based atlas of white matter tracts; subsequently, volume, mean diffusivity, and fractional anisotropy were extracted from superior cerebellar peduncles. These measures were compared across groups, and their discriminative power in differentiating patients was evaluated in a linear discriminant analysis. RESULTS Compared with those with Parkinson disease and controls, patients with progressive supranuclear palsy with Richardson syndrome showed alterations of all superior cerebellar peduncle metrics (decreased volume and fractional anisotropy, increased mean diffusivity). Patients with progressive supranuclear palsy-parkinsonism had smaller volumes than those with Parkinson disease and controls and lower fractional anisotropy than those with Parkinson disease. Patients with progressive supranuclear palsy with Richardson syndrome had significantly altered fractional anisotropy and mean diffusivity in the left superior cerebellar peduncle compared with those with progressive supranuclear palsy-parkinsonism. Discriminant analysis with the sole use of significant variables separated progressive supranuclear palsy-parkinsonism from progressive supranuclear palsy with Richardson syndrome with 70% accuracy and progressive supranuclear palsy-parkinsonism from Parkinson disease with 74% accuracy. CONCLUSIONS We demonstrate the feasibility of an automated approach for extracting multimodal MR imaging metrics from the superior cerebellar peduncle in healthy subjects and patients with parkinsonian. We provide evidence that structural and diffusion measures of the superior cerebellar peduncle might be valuable for computer-aided diagnosis of progressive supranuclear palsy subtypes and for differentiating patients with progressive supranuclear palsy-parkinsonism from with those with Parkinson disease.
