RESUMO
BACKGROUND: Erector spinae plane block is a locoregional anaesthetic technique widely used in several different surgeries due to its safety and efficacy. The aim of this study is to assess its utility in spinal degenerative and traumatic surgery in western countries and for patients of Caucasian ethnicity. METHODS: Patients undergoing elective lower-thoracic and lumbar spinal fusion were randomised into two groups: the case group (n = 15) who received erector spinae plane block (ropivacaine 0.4% + dexamethasone 4 mg, 20 mL per side at the level of surgery) plus postoperative opioid analgesia, and the control group (n = 15) who received opioid-based analgesia. RESULTS: The erector spinae plane block group showed significantly lower morphine consumption at 48 h postoperatively, lower need for intraoperative fentanyl (203.3 ± 121.7 micrograms vs. 322.0 ± 148.2 micrograms, p-value = 0.021), lower NRS score at 2, 6, 12, 24, and 36 h, and higher satisfaction rates of patients (8.4 ± 1.2 vs. 6.0 ± 1.05, p-value < 0.0001). No differences in the duration of the hospitalisation were observed. No erector spinae plane block-related complications were observed. CONCLUSIONS: Erector spinae plane block is a safe and efficient opioid-sparing technique for postoperative pain control after spinal fusion surgery. This study recommends its implementation in everyday practice and incorporation as a part of multimodal analgesia protocols. TRIAL REGISTRATION: The study was approved by the local ethical committee of Romagna (CEROM) and registered on ClinicalTrials.gov (NCT04729049). It also adheres to the principles outlined in the Declaration of Helsinki and the CONSORT 2010 guidelines.

OBJECTIVE: To assess whether socio-economic disparities exist on access to care, treatment options and outcomes among patients with renal mass amenable of surgical treatment within the universal healthcare system. METHODS: Data of consecutive patients submitted to partial nephrectomy (PN) or radical nephrectomy (RN) at our Institution between 2017 and 2020 were retrospectively evaluated. Patients were grouped according to their income level (low, intermediate, and high) based on the Indicator of Equivalent Economic Situation national criterion. Survival analysis was performed. Cox regression models were employed to analyse the impact of socio-economic variables on survival outcomes. RESULTS: One thousand forty-two patients were included (841 PN and 201 RN). Patients at the lowest income level were found more likely symptomatic and with a higher pathological tumour stage in the RN cohort (p > 0.05). The guidelines adherence on surgical indication rate as well as the access to minimally invasive surgery did not differ according to patient's income level in both cohorts (p > 0.05). Survival curves were comparable among the groups. Cox regression analysis showed that none of the included socio-economic variables was associated with survival outcomes in our series. CONCLUSIONS: Universal healthcare system may increase the possibility to ensure egalitarian treatment modalities for patients with renal cancer.

SUMMARY: Simulated data are crucial for evaluating epistasis detection tools in genome-wide association studies. Existing simulators are limited, as they do not account for linkage disequilibrium (LD), support limited interaction models of single nucleotide polymorphisms (SNPs) and only dichotomous phenotypes or depend on proprietary software. In contrast, EpiGEN supports SNP interactions of arbitrary order, produces realistic LD patterns and generates both categorical and quantitative phenotypes. AVAILABILITY AND IMPLEMENTATION: EpiGEN is implemented in Python 3 and is freely available at https://github.com/baumbachlab/epigen. SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

Programs of donation after cardiocirculatory determination of death (DCD) are increasingly established in many countries to increase the availability of organs for transplantation. The use of abdominal normothermic regional reperfusion (A-NRP), shortening total warm ischemia time (tWIT), has been recently recommended by the European Society for Organ Transplantation (ESOT) to decrease the risk potentially associated with transplantation of grafts from DCD donors. We aimed to describe our transesophageal ultrasound (TEU)-guided technique to implement A-NRP in controlled DCD (cDCD) donors through femorofemoral venoarterial extracorporeal support, preventing coronary and cerebral reperfusion occluding the aorta with a balloon. After assessment of the central vascular structures, the use of TEU in real time guides the insertion of the guidewires and the balloon. Moreover, TEU allows us to verify the proper positioning of a venous cannula and aortic balloon. The entire procedure may be performed without the need for fluoroscopic or radiographic evaluation, or limiting the need for fluoroscopic or radiology assistance to a selected scenario of difficult or expected difficult cannulation and/or balloon insertion. The distribution of interventions as antemortem and postmortem reflects the scenario imposed by Italian laws regulating organ procurement in DCD donors.

Introduction: Water vapor intraprostatic injection (Rezum procedure) for benign prostatic hyperplasia (BPH) is one of the most promising minimally invasive surgical treatments. Five-year outcomes from the multicenter randomized controlled trial (RCT) demonstrated significant and durable urinary and sexual function results in selected patients. We compared the sexual and urinary outcomes of this procedure in patients satisfying inclusion criteria of the RCT with unselected patients. Materials and Methods: We prospectively followed all patients with symptomatic BPH who underwent Rezum therapy at eight institutions and analyzed the functional results. Patients were divided into two groups: patients who matched the 5-year RCT inclusion criteria (Group A) and patients who did not (Group B). The pre- and postoperative data, complications, presence of antegrade ejaculation, and urinary and sexual outcomes were periodically recorded. Results: A total of 426 patients were eligible for the study (232 in Group A and 194 in Group B). Patients in Group B had a higher American Society of Anesthesiologists score, prostate volume, and postvoid residual measurement. No difference was found in terms of preoperative International Prostate Symptom Score, International Index of Erectile Function, maximum urinary flow, and prostate-specific antigen. Longer operative time and higher number of vapor injections were required in Group B, with no differences in hospital stay, injection density, and complication rates. All the urinary and sexual outcomes improved with no differences between the two groups. The reintervention rate at the latest follow-up visit was 2.6% in Group A and 3.1% in Group B. Conclusions: In our large multicenter series, water vapor intraprostatic injections showed a safe and effective profile regardless of the prostate size, presence of indwelling catheter, antiplatelet/anticoagulant medications, and patients' comorbidities.

BACKGROUND: Water vapor therapy (Rezum®; Boston Scientific, Marlborough, MA, USA) for bladder outflow obstruction (BOO) due to benign prostatic enlargement (BPE) is a minimally invasive and innovative surgical technique. The aim of this study was to evaluate its mid-term results in a large multicentric cohort of Italian patients. METHODS: Patients with BPO and moderate to severe LUTS who underwent Rezum® (Boston Scientific) treatment from May 2019 to July 2021 were included in this study. Pre- and postoperative evaluation comprised full urological evaluation with urine culture, digital rectal examination, serum PSA, transrectal prostate ultrasound, uroflowmetry, post-void residual and IPSS, OAB-q SF, ICIQ-UI SF and IIEF-5, ejaculatory anterograde rate. Minimum follow-up was 12 months. Patients' subjective satisfaction was recorded with Patient Global Impression of Improvement (PGI-I) Scale together with any early or late reported complications, classified according to Clavien-Dindo Scale. Statistical analysis was conducted as appropriate. RESULTS: Overall, 352 patients were eligible for the analysis. Procedures were routinely done on an outpatient basis. Mean operative was 12 minutes. The catheter was left in place for a median of 7 days. After treatment, Q

The introduction of pathways to enrol deceased donors after cardio-circulatory confirmation of death (donation after circulatory death, DCD) is expanding in many countries to face the shortage of organs for transplantation. The implementation of normothermic regional reperfusion (NRP) with warm oxygenated blood is a strategy to manage in-situ the organs of DCD donors. This approach, an alternative to in-situ cold preservation, and followed by prompt retrieval and cold static storage and/or ex-vivo machine perfusion (EVMP), could be limited to abdominal organs (A-NRP) or extended to the thorax (thoraco-abdominal, TA-NRP. NRP is also referred to as extracorporeal interval support for organ retrieval (EISOR). The use of EISOR is increasing in Europe, even if variably regulated. A-NRP has been demonstrated to be effective in decreasing the risk associated with transplantation of abdominal organs from DCD donors, and was recommended by the European Society for Organ Transplantation (ESOT) in a recent consensus document. We aim to explain how we select the candidates for DCD, to describe our regionalized model for implementing EISOR provision, and to introduce the health care professionals involved in this complex process, with their strictly defined roles, responsibilities, and boundaries. Finally, we report the results of our program, recruiting cDCD donors over a large network of hospitals, all pertaining to a Local Health Authority (Azienda Unità Sanitaria Locale, AUSL) in Romagna, Italy.
RESUMO
INTRODUCTION: The management of complex trauma patient with concomitant brain injury and extra-cranial lesions is challenging since the requirement of a low pressure to limit the bleeding clashes with the need to maintain an adequate cerebral perfusion and to obtain a brain CT-scan.Here we present the use of REBOA as a bridge to CT scan in complex head and torso trauma. CASE PRESENTATION: A 59 years old male patient involved in a road traffic crash was admitted to our hospital after a car accident. He had a GCS of 3 with a left fixed pupil anisocoria. Despite right-sided chest decompression for pneumothorax and massive transfusion protocol for haemoperitoneum, blood pressure remained low; to temporally stabilize the patient and perform a brain CT scan a zone 1 REBOA was inserted and systolic blood pressure rose up from 60 mmHg to 110 mmHg. A brain CT scan highlighted a right subdural hematoma with a 8-mm midline shift. The patient went to the operating room to perform damage control surgery and, subsequently, a decompressive craniotomy. After 96 days of hospital stay, the patient was discharged at home with a complete neurological recovery. CONCLUSIONS: The achievement of a rapid brain CT scan in traumatic brain injury is often crucial and has a deep impact in changing surgical management; moreover, duration of cerebral herniation is associated with worse outcome and increased mortality.In the light of this, the use of REBOA in selected cases of complex head and torso trauma could allow to gain time to go to the CT room in safe conditions.
RESUMO
The present study aimed to assess the safety and efficacy of robot-assisted radical prostatectomy (RARP) in patients with prostate cancer (PCa) under anticoagulant (AC) and/or antiplatelet (AP) therapy, as compared to a control group, and to establish possible differences in postoperative-related morbidity. Data of all consecutive patients submitted to elective RARP for PCa from June 2017 to May 2020 at our institution were prospectively collected. Patients were divided according to the use of AC/AP therapy at surgery. The primary endpoint was to determine differences in 90-day postoperative complication rate, while secondary endpoints included differences in transfusion rate, readmission rate and postoperative oncological outcomes between the two groups. Sub-groups analysis was separately performed for patients undergoing pelvic lymphadenectomy and nerve-sparing procedures. Overall, 822 patients were included in the study and divided in 704 control-group patients (group A) and 118 patients under AC/AP therapy at surgery (group B). Despite the higher estimated blood loss between AC/AP takers and the control group, we did not find a significant difference in terms of 90-day postoperative complication rate, transfusion rate, readmission rate and postoperative oncological outcomes (all p > 0.05). In the cohort of patients undergoing nerve-sparing prostatectomy, a higher rate of complications and transfusions were found. At multivariate analysis, ASA score and ongoing medications were independently associated with complication in this sub-group. RARP can be safely and effectively performed in patients with PCa and ongoing AC/AP agents. Attention has to be paid in candidates for nerve-sparing procedures.

The possible role of JC virus in determining urinary tract involvement has only recently been recognized. The case of a man with laboratory-confirmed JC virus replication in the urine after a maintenance schedule of rituximab administered for a lymphoproliferative disorder is reported herein. The patient developed severe renal and urinary tract impairment, characterized by the onset of nephropathy, bilateral ureteral strictures, and a serious reduction in vesical compliance, ultimately requiring an ileal neobladder configuration. The renal and urinary tract involvement was finally attributed to JC virus reactivation. This observation suggests that renal and urinary tract diseases related to JC virus might be associated with long-term rituximab treatment.

BACKGROUND AND OBJECTIVE: Bone fragility has been linked to COVID-19 severity. The objective of this study was to evaluate whether a diagnosis of vertebral fracture (VF) increased mortality risk in COVID-19 patients and whether this effect was greater than in those without COVID-19. METHODS: We assessed VFs by computed tomography (CT) in a cohort of 501 patients consecutively admitted to the emergency department (ED) for clinical suspicion of SARS-CoV-2 infection during the first wave of pandemic emergency. Of those, 239 had a confirmed diagnosis of COVID-19. RESULTS: VF prevalence was similar between COVID-19 and non-COVID-19 groups (22.2 vs. 19%; p = 0.458). Death rates were similar between COVID-19 and non-COVID-19 groups at both 30 (15.8 vs. 12.2%; p = 0.234) and 120 days (21.8 vs. 17.6%; p = 0.236). The mortality risk was higher in COVID-19 patients either with one or multiple fractures compared to those without VFs, at 30 and 120 days, but statistical significance was reached only in those with multiple VFs (30-day HR 3.03, 95% CI 1.36-6.75; 120-day HR 2.91, 95% CI 1.43-5.91). In the non-COVID-19 group, the 30-day mortality risk was significantly higher in patients either with one (HR 7.46, 95% CI 3.12-17.8) or multiple fractures (HR 6.2, 95% CI 2.75-13.98) compared to those without VFs. A similar effect was observed at 120 days. After adjustment for age, sex and bone density, mortality risk remained associated with VFs in the non-COVID-19 group only. CONCLUSIONS: VFs were not independently associated with short-term mortality in patients with COVID-19, but they strongly increased mortality risk in those without COVID-19.

The aim of this study was to review the available literature on the efficacy and safety of the Rezum system for the treatment of symptomatic benign prostatic hyperplasia (BPH). A revision of literature up to January 2021 was carried out. Medline, Scopus, Web of Science, and PubMed archives were screened to identify all the relevant studies investigating the role of Rezum in the treatment of BPH. Randomized controlled trial (RCT), retrospective, prospective, observational, and comparative studies were included. Finally, 17 studies were included, five of which reporting data of a double blind Rezum RCT. Overall, 1,451 patients underwent Rezum procedure. All the studies performed a minimum of 3 months follow-up. Preoperatively, the mean International Prostate Symptom Score (IPSS) score was 19.8, mean Qmax was 9.2mL s1, and mean PVR was 142 cc. At 3 months after surgery, the mean IPSS score was 1.5, mean Qmax was 13.7mL s1, and mean PVR was 74 cc. Six studies investigated sexual function, most of them using the International Index of Erectile Function (IIEF)-5 questionnaire and a few also the Male Sexual Health Questionnaire (MSHQ). Preoperative mean IIEF-5 score was 18.5, and the mean MSHQ score was 7.4. At the 3 months follow-up, the mean IIEF-5 score was 16.4, and the mean MSHQ score was 9.62. None of the studies reported intraoperative complications. Rezum system is a novel minimally invasive treatment for symptomatic BPH using transurethral water vapor thermal energy. It represents a cost-effective and safe procedure with durable relief of lower urinary tract symptom, preservation of sexual function, low complications rate, and short recovery time.
RESUMO
Background: Holmium laser enucleation of the prostate (HoLEP) is considered a safe and effective treatment in case of bladder outlet obstruction (BOO). Despite technical execution has evolved over time, from the standard three-lobes to the more recent en-bloc approaches, data comparing these two techniques are missing. The aim of the present study was to describe our en-bloc HoLEP with early apical release technique and compare peri- and postoperative results with the classical three-lobe approach in a single referral center. Materials and Methods: We prospectively analyzed all consecutive cases between 2017 and 2019 divided according to the type of approach. Patients were preoperatively studied through instrumental assessment and clinical evaluation, using validated questionnaires and then postoperatively at specific time frames. Linear regression analysis was performed to evaluate possible predictor of continuous variables. All the procedures were carried out by one single expert surgeon. Results: Overall, 168 patients were included, of which 81 were treated with classical three-lobes and 87 with en-bloc with early apical release technique. The two cohorts were comparable related to preoperative features and postoperative complication rate. Mean enucleation time (ET), lasing time, amount of energy delivered, and overall operative time were significantly lower in en-bloc procedures (p < 0.05). Stepwise multivariable linear regression showed that en-bloc strategy can significantly predict shorter ET and lower energy delivered. Stress incontinence rate at 1-month follow-up was found to be significantly reduced in the en-bloc group, compared with the counterpart. Conclusions: Both techniques are effective and safe treatment options for BOO, since peri- and postoperative surgical and functional outcomes were favorable. En-bloc strategy may significantly decrease ET and the amount of energy delivered leading to a reduced early stress incontinence rate compared with the standard approach.

OBJECTIVES: To explore the perspective of urological patients on the possibility to defer elective surgery due to the fear of contracting COVID-19. METHODS: All patients scheduled for elective urological procedures for malignant or benign diseases at 2 high-volume centers were administered a questionnaire, through structured telephone interviews, between April 24 and 27, 2020. The questionnaire included 3 questions: (1) In light of the COVID-19 pandemic, would you defer the planned surgical intervention? (2) If yes, when would you be willing to undergo surgery? (3) What do you consider potentially more harmful for your health: the risk of contracting COVID-19 during hospitalization or the potential consequences of delaying surgical treatment? RESULTS: Overall, 332 patients were included (51.5% and 48.5% in the oncology and benign groups, respectively). Of these, 47.9% patients would have deferred the planned intervention (33.3% vs 63.4%; P < .001), while the proportion of patients who would have preferred to delay surgery for more than 6 months was comparable between the groups (87% vs 80%). These answers were influenced by patient age and American Society of Anesthesiologists score (in the Oncology group) and by the underlying urological condition (in the benign group). Finally, 182 (54.8%) patients considered the risk of COVID-19 potentially more harmful than the risk of delaying surgery (37% vs 73%; P < .001). This answer was driven by patient age and the underlying disease in both groups. CONCLUSIONS: Our findings reinforce the importance of shared decision-making before urological surgery, leveraging patients' values and expectations to refine the paradigm of evidence-based medicine during the COVID-19 pandemic and beyond.

INTRODUCTION: Retrograde ureteroscopy (URS), intra-renal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) represent routine interventions for the treatment of ureteral and renal stones, although at times associated with serious adverse events. Of note, the evidence on perioperative complications after these procedures remains sparse and controversial. Moreover, there is a lack of standardized reporting of adverse events using uniform systems. The aim of the present study was to systematically review of the available evidence on URS/RIRS and PCNL for the surgical treatment of urinary stone, assessing the incidence of intra- and postoperative events, classified according to the modified Clavien-Dindo scale. EVIDENCE ACQUISITION: A systematic review of the literature was performed according to PRISMA recommendations and was conducted on intra- and postoperative complications, as well as on their management, following URS, RIRS and PCNL procedures, particularly focusing on major events. EVIDENCE SYNTHESIS: Overall, 26 studies (13 on URS/RIRS and 11 on PCNL) met the inclusion criteria and were evaluated. The highest intraoperative complication rate was 11.5% and 8.5% for RIRS and PCNL, respectively. Major complication rate following URS/RIRS and PCNL ranged between 0.3-31.7% and 2-17.1%, respectively. The most frequent adverse events were obstructive pyelonephritis or urinary leakage requiring the placement of a double J stent or a drainage. Among PCNLs series, life-threatening adverse events have also been reported, including bleeding requiring renal angioembolization and urothorax. CONCLUSIONS: Despite the inclusion of series using a standardized reporting system, the complication rate after URS/RIRS/PCNL remains extensively heterogeneous in the literature; in addition, a non-negligible proportion of studies did not characterize the adverse events nor report the actual management strategy to solve them. Future research is needed to standardize the classification and reporting of surgical complications after endourological procedures (taking into consideration the surgeon's experience and skills), aiming to improve patient counseling and potentially the strategy for their prevention.

OBJECTIVE: To evaluate the impact of preoperative markers of systemic inflammation on complications and oncological outcomes in patients aged ≥75 years treated with radical cystectomy (RC) for urothelial bladder cancer (UBC). PATIENTS AND METHODS: The clinical data of 694 patients treated with open RC for UBC at our institution between January 2008 and December 2015 were retrospectively reviewed. Patients aged <75 years, with distant metastases, other-than-urothelial histological type, comorbidities that could affect the systemic inflammatory markers, and patients who received neoadjuvant chemotherapy were excluded. Multivariable regression models were built for the prediction of major postoperative surgical complications, disease recurrence, cancer-specific mortality (CSM), and overall mortality (OM). RESULTS: The median (interquartile range [IQR]) age at surgery was 79 (75-83) years. Major postoperative surgical complications were registered in 41.9% of the patients. The 5-year overall survival, cancer-specific survival and recurrence-free survival rates were 42.4% (95% confidence interval [CI] 34.7-49.9%), 70.3% (95% CI 62.3-76.9%), and 59.8% (95% CI 52.4-66.5), respectively. At multivariable analysis, higher levels of fibrinogen and a modified Glasgow Prognostic Score (mGPS) of 1 and 2 at baseline were independently associated with higher risk of major postoperative complications and of CSM. The inclusion of mGPS and fibrinogen to a standard multivariable model for recurrence and for CSM increased discrimination from 69.4% to 73.0% and from 71.3% to 73.9%, respectively. Preoperative neutrophil-to-lymphocyte ratio of >3 was independently associated with OM (hazard ratio 1.38, 95% CI 1.01-1.77; P = 0.01). CONCLUSIONS: In a cohort of elderly patients with UBC treated with RC, fibrinogen and mGPS appeared to be the most relevant prognostic measurements and increased the accuracy of clinicopathological preoperative models to predict major postoperative complications, disease recurrence and mortality.

RESUMO
BACKGROUND: This study was conceived to provide systematic data about lung mechanics during early phases of CoVID-19 pneumonia, as long as to explore its variations during prone positioning. METHODS: We enrolled four patients hospitalized in the Intensive Care Unit of "M. Bufalini" hospital, Cesena (Italy); after the positioning of an esophageal balloon, we measured mechanical power, respiratory system and transpulmonary parameters and arterial blood gases every 6 hours, just before decubitus change and 1 hour after prono-supination. RESULTS: Both respiratory system and transpulmonary compliance and driving pressure confirmed the pseudo-normal respiratory mechanics of early CoVID-19 pneumonia (respectively, CRS 40.8 ml/cmH2O and DPRS 9.7 cmH2O; CL 53.1 ml/cmH2O and DPL 7.9 cmH2O). Interestingly, prone positioning involved a worsening in respiratory mechanical properties throughout time (CRS,SUP 56.3 ml/cmH2O and CRS,PR 41.5 ml/cmH2O - P 0.37; CL,SUP 80.8 ml/cmH2O and CL,PR 53.2 ml/cmH2O - P 0.23). CONCLUSIONS: Despite the severe ARDS pattern, respiratory system and lung mechanical properties during CoVID-19 pneumonia are pseudo-normal and tend to worsen during pronation. TRIAL REGISTRATION: Restrospectively registered.
RESUMO
INTRODUCTION: To investigate the influence of the body weight on peri- and postoperative outcome in a series of pediatric patients with a diagnosis of uretero-pelvic junction obstruction (UPJO) treated with robot-assisted laparoscopic pyeloplasty (RALP) at a single tertiary referral center. OBJECTIVE: In this study, outcomes of RALP in children divided according to the weight are evaluated. STUDY DESIGN: Sixty-one consecutive patients treated with RALP from January 2016 to May 2019 were recorded retrospectively and divided according to their weight: group A < 15 kg, group B ≥ 15 kg and were included in this study. Eligible criteria for surgery were symptomatic UPJO, worsening of hydronephrosis, or obstructive pattern at renogram. Success criteria were the reduction of the hydronephrosis at imaging and the absence of flank pain. All procedures were performed by one expert robotic surgeon. RESULTS: 18 patients were included in group A (median weight 12 kg) and 43 patients in group B (median weight 33 kg). The median (IQR) operative was 95 (90-120) for group A compared to 90 (85-110) of control group. No significant difference has been found (P = 0.93). We registered one (5.6%) Clavien 3b complication (omental hernia after removal of the drainage requiring surgical correction) and two (4.7%) Clavien 2 complication in group B (urinary infections). No difference has been found in the length of hospital stay, length of catheterization, and duration of procedure between the groups (P > 0.05). At a median follow-up of 23 months (IQR 9-27 vs 9-33), the success rate was comparable between the two groups (94.4% vs 97.7%; P = 0.51). Relapse was recorded in one child per group and both required nephrostomy placement. DISCUSSION: Our study tried to fill the gaps in the evidence on the feasibility of RALP in low-weight children reporting favorable peri-operative and long-term outcomes; however, this study shows some intrinsic limitations. The relatively small numbers of patients in the <15 kg may have underpowered the comparison with heavier patients. Moreover, only two patients were <10 kg so that no definitive conclusions on the safety and feasibility of RALP in this cohort of patients can be drawn. CONCLUSION: RALP in children <15 kg was feasible and effective to treat UPJO with superimposable results to heavier counterparts. In our experience, the need for a different trocar placement and limited space in patients <15 kg did not affect peri-operative and functional outcomes.

BACKGROUND: Iron metabolism and immune response to SARS-CoV-2 have not been described yet in intensive care patients, although they are likely involved in Covid-19 pathogenesis. METHODS: We performed an observational study during the peak of pandemic in our intensive care unit, dosing D-dimer, C-reactive protein, troponin T, lactate dehydrogenase, ferritin, serum iron, transferrin, transferrin saturation, transferrin soluble receptor, lymphocyte count and NK, CD3, CD4, CD8 and B subgroups of 31 patients during the first 2 weeks of their ICU stay. Correlation with mortality and severity at the time of admission was tested with the Spearman coefficient and Mann-Whitney test. Trends over time were tested with the Kruskal-Wallis analysis. RESULTS: Lymphopenia is severe and constant, with a nadir on day 2 of ICU stay (median 0.555 109/L; interquartile range (IQR) 0.450 109/L); all lymphocytic subgroups are dramatically reduced in critically ill patients, while CD4/CD8 ratio remains normal. Neither ferritin nor lymphocyte count follows significant trends in ICU patients. Transferrin saturation is extremely reduced at ICU admission (median 9%; IQR 7%), then significantly increases at days 3 to 6 (median 33%, IQR 26.5%, p value 0.026). The same trend is observed with serum iron levels (median 25.5 µg/L, IQR 69 µg/L at admission; median 73 µg/L, IQR 56 µg/L on days 3 to 6) without reaching statistical significance. Hyperferritinemia is constant during intensive care stay: however, its dosage might be helpful in individuating patients developing haemophagocytic lymphohistiocytosis. D-dimer is elevated and progressively increases from admission (median 1319 µg/L; IQR 1285 µg/L) to days 3 to 6 (median 6820 µg/L; IQR 6619 µg/L), despite not reaching significant results. We describe trends of all the abovementioned parameters during ICU stay. CONCLUSIONS: The description of iron metabolism and lymphocyte count in Covid-19 patients admitted to the intensive care unit provided with this paper might allow a wider understanding of SARS-CoV-2 pathophysiology.

Objectives: Robot-assisted radical prostatectomy (RARP) has been established as first-line surgical therapy for organ-confined prostate cancer (PCa). Pelvic lymph node dissection (PLND) is recommended in case of intermediate and high-risk localized PCa however symptomatic lymphocele (SL) formation is a common complication. Still no certain clinical and surgical predictors of SL have been found in the robotic era. Aim of this study was to identify clinical and surgical predictors of SL after RARP and PLND.Methods: We retrospectively evaluated all consecutive patients undergone RARP and PLND from 01/2017 to 06/2019, at our institution. All procedures were performed by experienced robotic surgeons. Baseline patients' characteristics, as well as peri- and post-operative features, were recorded and compared among those patients experiencing SL after surgery and those who did not.Results: Overall, 282 patients were included. Of these, 21 (7.5%) developed SL after surgery. Patients with SL showed higher median BMI (30.4 vs 25.8) and a more frequent history of vascular surgery or lymph-vascular disease (23.8% vs 8.4%) compared to patients without SL (p < 0.05). The lymphadenectomy technique adopted during the surgery was also found different in patients diagnosed with SL. At the multivariable analysis (MVA), only the increase of BMI (OR 1.72; CI: 1.47 - 2.81) was found predictor of developing SL.Conclusion: In our experience, the increase of BMI was a significant predictor of SL development in pCa patients submitted to RARP and PLND. This further evidence may be of great help for clinicians in daily clinical practice, in particular during preoperative counseling.
