Confirmatory validation analysis of the PROFFIT questionnaire to assess financial toxicity in cancer patients.

BACKGROUND: The Patient Reported Outcome for Fighting FInancial Toxicity (PROFFIT) questionnaire was developed to measure financial toxicity (FT) and identify its determinants. The aim of the present study was to confirm its validity in a prospective cohort of patients receiving anticancer treatment. PATIENTS AND METHODS: From March 2021 to July 2022, 221 patients were enrolled at 10 Italian centres. Selected items of the EORTC-QLQ-C30 questionnaire represented the anchors, specifically, question 28 (Q-28) on financial difficulties, and questions 29-30 measuring global health status/quality of life (HR-QOL). The study had 80% power to detect a 0.20 correlation coefficient (r) between anchors and PROFFIT-score (items 1-7, range 0-100, 100 indicating maximum FT) with bilateral alpha 0.05 and 80% power. Confirmatory factor analysis was conducted. FT determinants (items 8-16) were described. RESULTS: Median age of patients was 65 years, 116 (52.5%) were females, 96 (43.4%) had low education level. Confirmatory factor analysis confirmed goodness of fit of the PROFFIT-score. Significant partial correlation of PROFFIT-score was found with Q-28 (r = 0.51) and HR-QOL (r = -0.23). Mean (SD) PROFFIT-score at baseline was 36.5 (24.9); it was statistically significantly higher for patients living in South Italy, those with lower education level, those who were freelancer/unemployed at diagnosis and those who reported significant economic impact from the COVID-19 pandemic. Mean (SD) scores of determinants ranged from 17.6 (27.1) for item 14 (support from medical staff) to 49.0 (36.3) for item 10 (expenses for medicines or supplements). PROFFIT-score significantly increased with worsening response to determinants. CONCLUSIONS: External validation of PROFFIT-score in an independent sample of patients was successful. The instrument is now being used in clinical studies.

An Italian multicenter retrospective real-life analysis of patients with brain metastases from renal cell carcinoma: the BMRCC study.

BACKGROUND: The treatment of patients with brain-spread renal cell carcinoma (RCC) is an unmet clinical need, although more recent therapeutic strategies have significantly improved RCC patients' life expectancy. Our multicenter, retrospective, observational study investigated a real-world cohort of patients with brain metastases (BM) from RCC (BMRCC). PATIENTS AND METHODS: A total of 226 patients with histological diagnosis of RCC and radiological evidence of BM from 22 Italian institutions were enrolled. Univariate and multivariate models were performed to investigate the impact of clinicopathological features and multimodal treatments on both overall survival (OS) from the BM diagnosis and intracranial progression-free survival (iPFS). RESULTS: The median OS from the BM diagnosis was 18.8 months (interquartile range: 6.2-43 months). Multivariate analysis confirmed the following as positive independent prognostic factors: a Karnofsky Performance Status >70% [hazard ratio (HR) = 0.49, 95% confidence interval (CI) 0.26-0.92, P = 0.0026] and a single BM (HR = 0.51, 95% CI 0.31-0.86, P = 0. 0310); in contrast, the following were confirmed as worse prognosis factors: progressive extracranial disease (HR = 1.66, 95% CI 1.003-2.74, P = 0.00181) and only one line of systemic therapy after the BM occurrence (HR = 2.98, 95% CI 1.62-5.49, P = 0.029). Subgroup analyses showed no difference in iPFS according to the type of the first systemic treatment [immunotherapy (IT) or targeted therapy (TT)] carried out after the BM diagnosis (HR = 1.033, 95% CI 0.565-1.889, P = 0.16), and revealed that external radiation therapy (eRT) significantly prolonged iPFS when combined with IT (10.7 months, 95% CI 4.9-48 months, P = 0.0321) and not when combined with TT (9.01 months, 95% CI 2.7-21.2 months, P = 0.59). CONCLUSIONS: Our results suggest a potential additive effect in terms of iPFS for eRT combined with IT and encourage a more intensive multimodal therapeutic strategy in a multidisciplinary context to improve the survival of BMRCC patients.

3D printing and 3D bioprinting technology in medicine: ethical and legal issues.

Abstract: There has been a surge of interest in new technologies in medicine because of their promising clinical applications. Extensive research on additive manufacturing and its applications in the medical field has been carried out with good results and very high expectations. Due to their disruptive nature and potential, 3D printing and even more 3D bioprinting raise many ethical and safety concerns that need to be adequately addressed to provide good regulation before entering clinical practice. This article aims to highlight the general ethical concerns associated with the use of additive manufacturing in medicine and the lack of current international regulatory directives to guide these experiments. Transparency about how these new medical devices are regulated and approved is a fundamental requirement to promote and improve public trust, efficiency, safety and quality.

Validation of the Meet-URO score in patients with metastatic renal cell carcinoma receiving first-line nivolumab and ipilimumab in the Italian Expanded Access Program.

BACKGROUND: The Meet-URO score allowed a more accurate prognostication than the International Metastatic RCC Database Consortium (IMDC) for patients with pre-treated metastatic renal cell carcinoma (mRCC) by adding the pre-treatment neutrophil-to-lymphocyte ratio and presence of bone metastases. MATERIALS AND METHODS: A post hoc analysis was carried out to validate the Meet-URO score on the overall survival (OS) of patients with IMDC intermediate-poor-risk mRCC treated with first-line nivolumab plus ipilimumab within the prospective Italian Expanded Access Programme (EAP). We additionally considered progression-free survival (PFS) and disease response rates. Harrell's c-index was calculated to compare the accuracy of survival prediction. RESULTS: Overall the EAP included 306 patients, with a median follow-up of 12.2 months, median OS was not reached, 1-year OS was 66.8% and median PFS was 7.9 months. By univariable analysis, both the IMDC score and the two additional variables of the Meet-URO score were associated with either OS or PFS (P < 0.001 for all comparisons). The four Meet-URO risk groups (G) had 1-year OS of 92%, 72%, 50% and 21% for G2 (29.1% of patients), G3 (28.8%), G4 (33.0%) and G5 (9.1%), respectively. OS was significantly shorter in each consecutive G (P = 0.001 for G3, P < 0.001 for both G4 and G5 compared to G2). Similarly, Meet-URO Gs 2-5 showed decreasing median PFS and response rates. The Meet-URO score showed the highest c-index for both OS (0.73) and PFS (0.67). Limitations include the post hoc nature of this analysis and the lack of a comparative arm to assess predictive value. CONCLUSION: The Meet-URO score appeared to show better prognostic classification than the IMDC alone in patients with mRCC at IMDC intermediate-poor risk treated with first-line nivolumab and ipilimumab.

First-line avelumab for patients with PD-L1-positive metastatic or locally advanced urothelial cancer who are unfit for cisplatin.

BACKGROUND: Cisplatin-based chemotherapy is the most recommended treatment for metastatic urothelial cancer (mUC). However, about 50% of patients are considered to be cisplatin ineligible. Anti-programmed cell death protein 1/programmed death-ligand 1 (PD-L1) therapies have, nevertheless, increased the options available to clinicians and are especially valuable for treating these patients. This study therefore tested the activity and safety of avelumab as first-line therapy for mUC. PATIENTS AND METHODS: Patients with mUC who were ineligible for cisplatin-based chemotherapy were screened centrally for PD-L1 expression and only those with a tumour proportion score ≥ 5% were enrolled in the trial. The primary endpoint was 1-year overall survival (OS), and the secondary endpoints were median OS, median progression-free survival, overall response rate, duration of the response, safety and tolerability. All the survival rates were estimated with the Kaplan-Meier product-limit methodology and compared across groups using the log-rank test. RESULTS: A total of 198 patients were screened, with 71 (35.9%) whose PD-L1 expression was ≥5% enrolled in the study. The median age was 75 years, bladder cancer was the primary tumour in 73.2% of cases and 25.3% had liver metastases. The main reasons for the cisplatin ineligibility were a low rate of creatinine clearance (<60 ml/min), present in 70.4% of patients, and an Eastern Cooperative Oncology Group performance status of 2, which affected 31%. The median OS was 10.0 months (95% confidence interval 5.5-14.5 months) and 43% of patients were alive at 1 year. A complete response was achieved in 8.5% of cases, and 15.5% had a partial response. Adverse any-grade and high-grade events occurred in 49.3% and 8.5% of patients, respectively. A grade 3 infusion reaction was the only high-grade treatment-related adverse event. No treatment-related deaths were reported. CONCLUSIONS: This ARIES trial confirmed the activity and safety of avelumab for treating mUC, adding a new therapy option to the armamentarium of checkpoint inhibitors already approved for platinum-ineligible, locally advanced/mUC.

Objective and subjective evaluation of Velopharyngeal Dysfunction (VPD) following surgical repair of the cleft palate using the furlow palatoplasty - A new tool.

Velopharyngeal dysfunction (VPD) diagnosis and speech surgery outcomes are currently based solely on subjective evaluation criteria consisting of perceptual speech assessment and functional imaging. This study describes an objective and comparable method in VPD assessment and investigates the concurrence between the objective and subjective evaluations. The present study included 20 paediatric patients presenting with VPD after primary repair (intravelar veloplasty) of cleft palate. Our protocol was based on computerized analysis of voice parameters by means of an objective tool, spectrography integrated with Multi-Dimensional Voice Program (MDVP). The protocol also included perceptual evaluation by speech therapist and phoniatrician (consensus listening), and parents. This is a single surgeon, single centre experience and all patients underwent a secondary Furlow's palatoplasty. Assessments were performed pre- and postoperatively and upon completion of speech therapy. Results were compared using the two-tailed t student test for paired data. Statistical significance was set for p-values <0.05. Data analysis confirmed an improvement in velopharyngeal closure after surgery and speech therapy consistently with the results of perceptual evaluations. The results of the study confirmed the availability and reliability of an objective method for VPD evaluation based on the analysis of voice parameters with investigations that are simple and easily available in a hospital setting.

Engineered mucoperiosteal scaffold for cleft palate regeneration towards the non-immunogenic transplantation.

Cleft lip and palate (CL/P) is the most prevalent craniofacial birth defect in humans. None of the surgical procedures currently used for CL/P repair lead to definitive correction of hard palate bone interruption. Advances in tissue engineering and regenerative medicine aim to develop new strategies to restore palatal bone interruption by using tissue or organ-decellularized bioscaffolds seeded with host cells. Aim of this study was to set up a new natural scaffold deriving from a decellularized porcine mucoperiosteum, engineered by an innovative micro-perforation procedure based on Quantum Molecular Resonance (QMR) and then subjected to in vitro recellularization with human bone marrow-derived mesenchymal stem cells (hBM-MSCs). Our results demonstrated the efficiency of decellularization treatment gaining a natural, non-immunogenic scaffold with preserved collagen microenvironment that displays a favorable support to hMSC engraftment, spreading and differentiation. Ultrastructural analysis showed that the micro-perforation procedure preserved the collagen mesh, increasing the osteoinductive potential for mesenchymal precursor cells. In conclusion, we developed a novel tissue engineering protocol to obtain a non-immunogenic mucoperiosteal scaffold suitable for allogenic transplantation and CL/P repair. The innovative micro-perforation procedure improving hMSC osteogenic differentiation potentially impacts for enhanced palatal bone regeneration leading to future clinical applications in humans.

Two nasal swabs may not be enough to exclude SARS-CoV-2 infection in symptomatic patients.

Abstracts: The spread of COVID-19 (COronaVIrus Disease 2019), due to SARS-CoV-2 (Severe Acute Respiratory Syndrome CoronaVirus 2) has taken on dramatic pandemic proportions, affecting over 100 countries in a matter of weeks. Italy has had 237,828 confirmed cases according to the Istituto Superiore di Sanità as of May 13, and 34,448 deaths (1).

Daratumumab in multiple myeloma: experience of the multiple myeloma GIMEMA Lazio group.

Daratumumab (DARA) is a human IgG-K monoclonal antibody (MoAb) targeting CD38 that is approved alone or in combination with bortezomib and dexamethasone or lenalidomide and dexamethasone for relapsed or refractory MM (RRMM) in patients previously exposed or double refractory to proteasome inhibitors (PI) and immunomodulatory drugs (IMiDs). However, there are limited data on its clinical activity and tolerability in real-world patients. Therefore, in the present study, we aim to determine the efficacy and toxicity profile of daratumumab in a real-life setting. In this study, we report the experience of the multiple myeloma GIMEMA Lazio Group in 62 relapsed/refractory MM patients treated with daratumumab as monotherapy who had previously received at least two treatment lines including a PI and an IMiDs or had been double refractory. Patients received DARA 16 mg/kg intravenously weekly for 8 weeks, every 2 weeks for 16 weeks, and every 4 weeks until disease progression or unacceptable toxicity. The overall response rate to daratumumab was 46%. Median progression-free survival (PFS) and overall survival reached 2.7 and 22.4 months, respectively. DARA was generally well tolerated; however, 2 patients interrupted their therapy due to adverse events. Present real-life experience confirms that DARA monotherapy is an effective strategy for heavily pre-treated and refractory patients with multiple myeloma, with a favorable safety profile.

Amphetamines signal through intracellular TAAR1 receptors coupled to Gα13 and GαS in discrete subcellular domains.

The extensive use of amphetamines to treat attention deficit hyperactivity disorders in children provides a compelling rationale for understanding the mechanisms of action of amphetamines and amphetamine-related drugs. We have previously shown that acute amphetamine (AMPH) regulates the trafficking of both dopamine and glutamate transporters in dopamine neurons by increasing activation of the small GTPase RhoA and of protein kinase A. Here we demonstrate that these downstream signaling events depend upon the direct activation of a trace amine-associated receptor, TAAR1, an intracellular G-protein coupled receptor (GPCR) that can be activated by amphetamines, trace amines, and biogenic amine metabolites. Using cell lines and mouse lines in which TAAR1 expression has been disrupted, we demonstrate that TAAR1 mediates the effects of AMPH on both RhoA and cAMP signaling. Inhibition of different Gα signaling pathways in cell lines and in vivo using small cell-permeable peptides confirms that the endogenous intracellular TAAR1 couples to G13 and to GS α-subunits to increase RhoA and PKA activity, respectively. Results from experiments with RhoA- and PKA-FRET sensors targeted to different subcellular compartments indicate that AMPH-elicited PKA activation occurs throughout the cell, whereas G13-mediated RhoA activation is concentrated near the endoplasmic reticulum. These observations define TAAR1 as an obligate intracellular target for amphetamines in dopamine neurons and support a model in which distinct pools of TAAR1 mediate the activation of signaling pathways in different compartments to regulate excitatory and dopaminergic neurotransmission.

Foot and ankle measurements on cone beam weightbearing computed tomography.

Over the last years, an increased number of studies have reported the use of cone beam weightbearing computed tomography (WBCT) in the assessment of foot and ankle pathology. This new technology has enabled to overcome the limits inherently related to two-dimensional radiographs (superimposition bias, operator-related bias, rotation bias) and to obtain images reproducing the bones and joints anatomy during physiological standing with a low radiation dose. We performed a review of the current literature to summarize the evidence about the use of 2D or 3D measurements on WBCT images in various foot and ankle conditions. Our aims were to describe measurements proposed so far and to report data on reliability and validity from primary authors.

Blood loss and transfusion rate in patients undergoing two-stage exchange in infected total knee arthroplasty.

Two-stage exchange in infected total knee arthroplasty is a reliable technique, but it has a high rate of blood loss. The study aims to compare the pre-operative and post-operative haemoglobin levels, the rate of transfusion, and the blood loss in two-stage exchange. From July 2018 to July 2019, eighteen patients underwent two-stage exchange of their infected total knee arthroplasty. Local and systemic tranexamic acid was administered in both surgical stages. Calculated blood loss was 2246 mL (range 1528 - 2850) in the first stage and 2388 mL (1873 - 2829) during reimplantation, respectively. The corresponding transfusion rate was 55 % and 67%, respectively. With the numbers available, these differences were not significant. In conclusion, this study shows that the blood loss and transfusion rate are similar during the two stages of exchange knee arthroplasty for infection.

Use of synthetic cartilage implant (Cartiva®) for degeneration of the first and second metatarsophalangeal joint: what is the current evidence?

Polyvinyl alcohol hydrogel implants (also known as Synthetic Cartilage Implant or Cartiva® have been described in the treatment of degeneration of the first and second metatarsophalangeal joint (MTPJ). We reviewed literature to report characteristics of devices on the market and investigate their efficacy and safety. Following the PRISMA checklist, the Medline and Scopus databases were searched, including studies reporting use of Cartiva® for treating joint degeneration of the first and second MPTJ. Studies were searched for surgical technique, postoperative protocol, clinical scores, complications and reoperations. We found that, although some studies suggest that the use of Synthetic Cartilage Implant (Cartiva® is effective in the treatment of hallux rigidus in providing symptoms relief without sacrifice of joint motion, the redundancy of cohorts reported in studies and the frequency of conflict of interest reported by authors weaken the strength of evidence available and warrant further studies. Regarding the treatment of the second MTPJ ailments, no recommendation can be formulated to date due to the lack of primary studies.

A comparative study of combined intravenous and topical administration of tranexamic acid with topical tranexamic acid alone for blood loss reduction after primary uncemented total hip arthroplasty.

The aim of the present study was to evaluate the efficacy of topical versus combined (intravenous + topical) tranexamic acid (TXA) to reduce perioperative blood loss after uncemented primary total hip arthroplasty (THA). Seventy-five patients were randomized in three comparable experimental groups: 1) topical TXA (3 g in 50 ml of saline solution); 2) intravenous + topical TXA (3 g topical + 2 g in 100 ml of saline solution intravenously); 3) controls. Pre- and post-operative hemoglobin (Hb) levels and hematocrit (Hct) values along with the rate of blood transfusion in the 3 groups were compared. The intravenous + topical TXA group demonstrated higher Hb levels and Hct values at postoperative day one (Hb = p <0.05, Hct = p <0.001), postoperative day three (Hb = p <0.05, Hct = p <0.001), and discharge (Hct = p <0.01) compared to the control group. The intravenous + topical group had a lower transfusion rate compared to the control group (0% vs 20%, p = 0.014). With the numbers available, no difference in postoperative Hb level and transfusion rate emerged between topical TXA and control group.

Negative impact of hyperglycaemia on tocilizumab therapy in Covid-19 patients.

Tocilizumab (TCZ) is used for treating moderate-to-severe Covid-19 pneumonia by targeting interleukin-6 receptors (IL-6Rs) and reducing cytokine release. Yet, in spite of this therapy, patients with vs. patients without diabetes have an adverse disease course. In fact, glucose homoeostasis has influenced the outcomes of diabetes patients with infectious diseases. Of the 475 Covid-19-positive patients admitted to infectious disease departments (University of Bologna, University Vanvitelli of Napoli, San Sebastiano Caserta Hospital) in Italy since 1 March 2020, 31 (39.7%) hyperglycaemic and 47 (60.3%) normoglycaemic patients (blood glucose levels ≥140mg/dL) were retrospectively evaluated at admission and during their hospital stay. Of note, 20 (64%) hyperglycaemic and 11 (23.4%) normoglycaemic patients had diabetes (P<0.01). At admission, hyperglycaemic vs. normoglycaemic patients had fivefold higher IL-6 levels, which persisted even after TCZ administration (P<0.05). Intriguingly, in a risk-adjusted Cox regression analysis, TCZ in hyperglycaemic patients failed to attenuate risk of severe outcomes as it did in normoglycaemic patients (P<0.009). Also, in hyperglycaemic patients, higher IL-6 plasma levels reduced the effects of TCZ, while adding IL-6 levels to the Cox regression model led to loss of significance (P<0.07) of its effects. Moreover, there was evidence that optimal Covid-19 infection management with TCZ is not achieved during hyperglycaemia in both diabetic and non-diabetic patients. These data may be of interest to currently ongoing clinical trials of TCZ effects in Covid-19 patients and of optimal control of glycaemia in this patient subset.

Assessing forest availability for wood supply in Europe.

The quantification of forests available for wood supply (FAWS) is essential for decision-making with regard to the maintenance and enhancement of forest resources and their contribution to the global carbon cycle. The provision of harmonized forest statistics is necessary for the development of forest associated policies and to support decision-making. Based on the National Forest Inventory (NFI) data from 13 European countries, we quantify and compare the areas and aboveground dry biomass (AGB) of FAWS and forest not available for wood supply (FNAWS) according to national and reference definitions by determining the restrictions and associated thresholds considered at country level to classify forests as FAWS or FNAWS. FAWS represent between 75 and 95 % of forest area and AGB for most of the countries in this study. Economic restrictions are the main factor limiting the availability of forests for wood supply, accounting for 67 % of the total FNAWS area and 56 % of the total FNAWS AGB, followed by environmental restrictions. Profitability, slope and accessibility as economic restrictions, and protected areas as environmental restrictions are the factors most frequently considered to distinguish between FAWS and FNAWS. With respect to the area of FNAWS associated with each type of restriction, an overlap among the restrictions of 13.7 % was identified. For most countries, the differences in the FNAWS areas and AGB estimates between national and reference definitions ranged from 0 to 5 %. These results highlight the applicability and reliability of a FAWS reference definition for most of the European countries studied, thereby facilitating a consistent approach to assess forests available for supply for the purpose of international reporting.

Advances in bioengineering of complex tissues: state of the art of mucosae decellularization protocols.

The loss or deficiency of a tissue or organ is a serious health problem and severely affects the patients' quality of life. In the near future, an option for solving this problem will be the development of bio-derived extracellular matrices (ECM) from huPlastic Romaman or animal tissues and their usage for in vitro or in vivo cellular reseeding. Many researchers are working on this development. Nowadays, different decellularization protocols have been developed to manufacture ECMs but there is not yet a consensus about the most efficient procedures. This review aims to describe the state of the art in the field of decellularization of complex mucosal tissues, analizing and comparing the most recent and most valiant articles published about this procedure.
