Abstract	This paper discusses the notion of cointegrating space for linear processes integrated of any order. It first shows that the notions of (polynomial) cointegrating vectors and of root functions coincide. Second, it discusses how the cointegrating space can be defined (i) as a vector space of polynomial vectors over complex scalars, (ii) as a free module of polynomial vectors over scalar polynomials, or finally (iii) as a vector space of rational vectors over rational scalars. Third, it shows that a canonical set of root functions can be used as a basis of the various notions of cointegrating space. Fourth, it reviews results on how to reduce polynomial bases to minimal order—i.e., minimal bases. The application of these results to Vector AutoRegressive processes integrated of order 2 is found to imply the separation of polynomial cointegrating vectors from non-polynomial ones.

Abstract	The present paper employs the infinite order error correction representation of the observables of a I(1) state space system and analyzes by simulation the small sample behaviour of the test on rank and on the cointegrating vectors calculated via a finite order cointegrated vector autoregressive approximation. The rank test performs very well in systems with a small number of states and stochastic trends (≤4) and a medium number of observables (≤35) already for a sample of size T=300 and it is still reliable with a large number of observables (≤140) when T=600. The behaviour of the test on the cointegrating vectors is more problematic.

Abstract	Background: Previous reviews on hysterectomy versus uterine-sparing surgery in pelvic organ prolapse (POP) repair did not consider that the open abdominal approach or transvaginal mesh use have been largely abandoned. Objectives: To provide up-to-date evidence by examining only studies investigating techniques currently in use for POP repair. Search strategy: MEDLINE and Embase databases were searched from inception to January 2023. Selection criteria: We included randomized and non-randomized studies comparing surgical procedures for POP with or without concomitant hysterectomy. Studies describing open abdominal approaches or transvaginal mesh implantation were excluded. Data collection and analysis: A random effect meta-analysis was conducted on extracted data reporting pooled mean differences and odds ratios (OR) between groups with 95% confidence intervals (CI). Main results: Thirty-eight studies were included. Hysterectomy and uterine-sparing procedures did not differ in reoperation rate (OR 0.93; 95% CI 0.74-1.17), intraoperative major (OR 1.34; 95% CI 0.79-2.26) and minor (OR 1.38; 95% CI 0.79-2.4) complications, postoperative major (OR 1.42; 95% CI 0.85-2.37) and minor (OR 1.18; 95% CI 0.9-1.53) complications, and objective (OR 1.38; 95% CI 0.92-2.07) or subjective (OR 1.23; 95% CI 0.8-1.88) success. Uterine preservation was associated with a shorter operative time (-22.7 min; 95% CI -16.92 to -28.51 min), shorter hospital stay (-0.35 days, 95% CI -0.04 to -0.65 days), and less blood loss (-61.7 mL; 95% CI -31.3 to -92.1 mL). When only studies using a laparoscopic approach for both arms were considered, no differences were observed in investigated outcomes between the two groups. Conclusions: No major differences were observed in POP outcomes between procedures with and without concomitant hysterectomy. The decision to preserve or remove the uterus should be tailored on individual factors.

Abstract	The 5th generation of mobile networks has come to the market bringing the promise of disruptive performances as low latency, availability and reliability, imposing the development of the so-called "killer applications". This contribution presents a 5G use case in the context of Structural Health Monitoring which guarantees an unprecedented level of reliability when exploited for public safety purposes as Earthquake Early Warning. The interest on this topic is at first justified through a deep market analysis, and subsequently declined in terms of public safety benefits. A specific sensor board, guaranteeing real-time processing and 5G connectivity, is presented as the foundation on which the architecture of the network is designed and developed. Advantages of 5G-enabled urban safety are then discussed and proven in the experimentation results, showing that the proposed architecture guarantees lower latency delays and overcome the impairments of cloud solutions especially in terms of delays variability.

Abstract	Cytotoxic lesions of the corpus callosum (CLOCCs) are a clinical-radiological spectrum of disorders secondary to several etiopathogeneses. Cytotoxic lesions of the corpus callosum are typically associated with mild clinical symptoms including fever, headache, confusion, and altered mental status. We present a case of a 51-year-old Caucasian woman who developed a reversible lesion of the splenium of the corpus callosum associated with small round-shaped white matter hyperintensities after the first dose of SARS-CoV-2 mRNA vaccine. Magnetic resonance imaging is fundamental for diagnosis and no treatment is generally required.

Abstract	The outcome of liver transplantation (LT) for hepatocarcinoma (HCC) is strongly influenced by HCC staging, which is based on radiological examinations in a pre-LT setting; concordance between pre-LT radiological and definitive pathological staging remains controversial. To address this issue, we retrospectively analyzed our LT series to assess concordance between radiology and pathology and to explore the factors associated with poor concordance and outcomes. We included all LTs with an HCC diagnosis performed between 2013 and 2018. Concordance (Co group) was defined as a comparable tumor burden in preoperative imaging and post-transplant pathology; otherwise, non-concordance was diagnosed (nCo group). Concordance between radiology and pathology was observed in 32/134 patients (Co group, 24%). The number and diameter of the nodules were higher when nCo was diagnosed, as was the number of pre-LT treatments. Although concordance did not affect survival, more than three pre-LT treatments led to a lower disease-free survival. Patients who met the Milan Criteria (Milan-in patients) were more likely to receive ≥three prior treatments, leading to a lower survival in multi-treated Milan-in patients than in other Milan-in patients. In conclusion, the concordance rate between the pre-LT imaging and histopathological results was low in patients with a high number of nodules. Multiple bridging therapies reduce the accuracy of pre-LT imaging in predicting HCC stages and negatively affect outcomes after LT.

Abstract	Background: Genitourinary syndrome of menopause (GSM) is a widespread condition with a great impact on quality of life and self-image. Aim: We aimed to systematically review the current literature on CO2-Laser therapy efficacy for the treatment of GSM. Methods: MEDLINE and Embase databases were systematically queried in December 2020 Studies included women with a diagnosis of Vulvo-Vaginal Atrophy (VVA) or GSM without an history of gynaecological and/or breast cancer, pelvic organ prolapse staged higher than 2, pelvic radiotherapy or Sjogren's Syndrome. The quality of the evidence was assessed with the Cochrane risk of bias tool. This study is registered on PROSPERO, number CRD42021238121. Outcomes: Effects of CO2-Laser therapy on GSM symptoms assessed through subjective or objective efficacy measurement methods. Results: A total of 803 articles were identified. Of these, 25 studies were included in this review for a total of 1,152 patients. All studies showed a significant reduction in VVA and/or GSM symptoms (dryness, dyspareunia, itching, burning, dysuria). The pooled mean differences for the symptoms were: dryness -5.15 (95% CI:-5.72,-4.58; P < .001; I Clinical implications: Vaginal laser treatment resulted in both a statistically and clinically significant improvement in GSM symptoms. FSFI improved significantly in all 8 included studies but it reached a clinically relevant level only in 2 of them. Strengths & limitations: The strength of the current meta-analysis is the comprehensive literature search. We reported data from a high number of patients (1,152) and high number of laser applications (more than 3,800). The main limitations are related to the high heterogeneity of the included studies investigating laser effects. Moreover, most of them are single center and nonrandomized studies. Conclusion: The data suggest that CO2-Laser is a safe energy-based therapeutic option for the management of VVA and/or GSM symptoms in postmenopausal women; however, the quality of the body of evidence is "very low" or "low".
