    Abstract Osteoarthritis (OA) is a degenerative and progressive joint disease. When all three compartments are involved, end-stage OA is treated with a total knee arthroplasty (TKA). Unicompartmental knee arthroplasty (UKA) is a primary treatment for isolated osteoarthritis. UKA has a quicker recovery time than TKA, as well as less morbidity and more tissue sparing. At the time of surgery, 17% of patients have a tricompartmental disease and most patients with a Kellegren-Lawrence grade >3 have an intact anterior cruciate ligament (ACL). Conventional TKA sacrifices the ACL. Patients with concurrent medial and lateral osteoarthritis and a functional ACL may receive a primary bi-unicondylar arthroplasty. Combined partial knee arthroplasty (CPKA) is an established practice either in bicompartmental femoro-tibial OA or in OA progression after UKA, with the addition of another UKA. A conversion of a lateral UKA to a tricompartmental joint replacement has been reported in the literature. In our case report, we describe a one-stage hypoallergenic tricompartmental UKA, with improved clinical score and no sign of early failure at the last follow-up.

    Abstract Purpose: It is debatable whether or not previous high tibial osteotomy (HTO) has negative effects on the results of subsequent medial unicompartmental knee replacement (UKR). The purpose of this study is to report, through a systematic review of the literature, the outcomes of medial UKR after failed HTO. It was hypothesized that this procedure would be safe and effective in providing satisfactory postoperative functional outcomes.
    Methods: A systematic review was performed by searching Pubmed/MEDLINE, Embase and CINAHL. Only studies in English pertaining to all levels of evidence reporting on subjects undergoing UKR following HTO were considered. Review articles and expert opinion or editorial pieces were excluded. Outcomes of interest included indications, surgical technique and associated procedures, type of prosthesis, clinical and functional outcomes, rate of complications, revision surgery and failure rate.
    Results: Overall, six studies met all the inclusion criteria for this review. All were published between 2006 and 2021. The search resulted in one prospective comparative study, four retrospective comparative cohort studies, and one retrospective cohort study. Average follow-up periods ranged from 1 to 13 years. From these studies, 115 patients (117 knees) were identified. Overall, most studies reported satisfying postoperative clinical and functional outcomes. Implant survivorship ranged from 66 to 97.6%. In 15 patients, revision surgery was performed due to persistent pain.
    Conclusions: Medial UKR performed after failed HTO appears as a feasible procedure providing satisfying outcomes and limited complications in most cases. Further prospective comparative studies reporting long-term outcomes are needed, as high-level studies on this topic are lacking.

    Abstract Background: Transglutaminase 2 is an ubiquitously multifunctional enzyme and the most widely studied of the transglutaminase family. Consistent with its role in promoting post-translational modifications of proteins, Transglutaminase 2 is involved in many physiological processes such as apoptosis, signal transduction, and cellular adhesion. Several findings indicate that Transglutaminase 2 plays a role in the pathological processes of various inflammation-related diseases, including neurodegenerative diseases.
    Objective: We tested the potential modulatory effects on amyloid-β-induced Transglutaminase 2 expression and activities of 2-pentadecyl-2-oxazoline, a plant-derived agent, which has shown effectiveness against chronic pain and associated neuropsychiatric disorders, both in mouse and human microglial cell lines.
    Methods: We used biochemistry, molecular and cell biology techniques to evaluate the potential modulatory effects on amyloid-β-induced Transglutaminase 2 expression and activities of 2- pentadecyl-2-oxazoline in mouse and human microglial cell lines.
    Results: 2-pentadecyl-2-oxazoline was able to modulate amyloid-β-induced Transglutaminase 2 expression and activities in mouse and human microglial cell lines.
    Conclusion: Transglutaminase 2 confirms its role as a neuroinflammation marker, the inhibition of which could be a potential preventive and therapeutic approach, while 2-pentadecyl-2-oxazoline is a potent modulator of the amyloid-β-induced Transglutaminase 2 expression and activities in mouse and human microglial cell lines.

    Abstract Objective: The aim of this study was to assess the functional, radiological, and clinical outcomes of patellofemoral joint in patients who had total knee arthroplasty (TKA) without patellar resurfacing for end-stage osteoarthritis using inverse restricted kinematic alignment (irKA) compared to a control group using adjusted mechanical alignment (aMA), both executed with the same implant at the same Institution. The hypothesis was that patients undergoing TKA without patellar resurfacing for end-stage osteoarthritis using irKA would have superior outcomes related to the patellofemoral joint in comparison to a control group using aMA.
    Methods: A retrospective examination of registries' prospectively obtained from patients who underwent primary TKA at our Institution between 2016 and 2020 was performed. 40 consecutive patients who underwent TKA implant using irKA were compared to a control group of 80 who had undergone adjusted mechanically-aligned TKA. Groups were matched for age and body mass index. Clinical assessment included Visual Analog Scale (VAS), Knee Osteoarthritis Outcome Score (KOOS), Knee Society Score (KSS), and Kujala Knee Score. Standard weight-bearing anteroposterior and lateral view x-rays were used for radiographic evaluation. Patellar height was assessed using Caton-Deschamps (C-D) and Insall index on lateral view films.
    Results: In comparison to pre-operative status, both groups had postoperative improvements in VAS, KOOS, KSS, and Kujala ratings (p
    Conclusion: Improvements in post-operative clinical and functional outcomes following TKA were associated with either irKA or aMA. There were no discernible changes between the two groups in terms of postoperative patellofemoral discomfort or variations in patellar height.

    Abstract Introduction: The influence of a previous high tibial osteotomy (HTO) on the outcome and survival of a knee arthroplasty is a debated issue. The purpose of this study is to compare subjective, radiographic, and functional outcomes of unicompartmental knee replacement (UKR) and total knee replacement (TKR) after failed open wedge HTO.
    Methods: 26 post-HTO UKRs (group A) with an average follow-up of 7.8 years (range 2-13), and 33 post-HTO TKRs (group B) with an average follow-up of 11.2 years (range 4-16) operated between 2001 and 2017, were retrospectively reviewed. Assessment included Knee Society Score (KSS), University of California at Los Angeles Activity Score (UCLA), and Western Ontario and McMaster University Osteoarthritis Index (WOMAC). Standard knee X-rays, and long-standing X-rays were performed pre-operatively and at follow-up to evaluate prosthesis survival, coronal alignment, and patellar height.
    Results: Improvements regarding KSS, UCLA and WOMAC scores were noted at follow-up in both groups compared to pre-operatory status (p < 0.001). No statistically significant differences in clinical and functional postoperative scores were reported between groups (p = n.s.) at follow-up. Group B presented a more neutral mean mechanical axis of 0.5° compared to 2.7° in Group A (p < 0.001).
    Conclusions: Performing UKR after previous failed HTO is a safe and effective procedure which leads to clinical, radiological and functional outcomes comparable to TKR after HTO.

    Abstract Background: Controversy exists whether or not a previous high tibial osteotomy (HTO) influences the outcome and survival of a unicompartmental knee arthroplasty (UKA). The aim of this retrospective study was to evaluate clinical, radiological, and functional outcomes of UKA after failed open-wedge HTO compared with UKA with no previous HTO.
    Methods: Between 2001 and 2017, 24 post-HTO UKAs (group A) with an average follow-up of 8.1 years (range: 5 to 13) were compared with a control group of 30 patients undergoing simple UKA (group B) with an average follow-up of 9.5 years (range: 2 to 16). All patients were evaluated preoperatively and postoperatively using Knee Society Score, University of California at Los Angeles Activity Score, Western Ontario and McMaster University Osteoarthritis Index, and through objective evaluation. Mechanical coronal alignment and Caton-Deschamps index were measured both preoperatively and postoperatively.
    Results: In both groups, Knee Society Score, University of California at Los Angeles Activity Score, and Western Ontario and McMaster University Osteoarthritis Index scores significantly improved at follow-up (P < .001). In addition, statistically significant greater improvements in clinical and functional scores were reported in group B compared with group A (P < .001). No statistically significant differences concerning postoperative mechanical axis were observed between groups (2.7° and 3.2°, respectively, P = .27) and with regard to Caton-Deschamps index (1.0° and 1.1°, respectively, P = .44).
    Conclusion: This study demonstrated improvements in clinical and functional outcomes compared with preoperatory status in both groups irrespective of a previous HTO. A prior HTO was a determinant for having reduced postoperative clinical and functional outcomes after UKA.

    Abstract Background: Lung cancer remains the leading cause of cancer-related death worldwide. Targeted therapies with tyrosine kinase inhibitors (TKIs) result in improvement in survival for non-small cell lung cancer (NSCLC) with activating mutations of the epidermal growth factor receptor (EGFR). Unfortunately, most patients who initially respond to EGFR-TKI ultimately develop resistance to therapy, resulting in cancer progression and relapse. Combination therapy is today a common strategy for the treatment of tumors to increase the success rate, improve the outcome and survival of patients, and avoid the selection of resistant cancer cells through the activation of compensatory pathways. In NSCLC, the phosphoinositide-3-kinase/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway has been heavily implicated in both tumorigenesis and the progression of disease.
    Objectives: In this study, we investigated the efficacy of a PI3K δ-sparing inhibitor, MEN1611, in models of NSCLC sensitive and resistant to EGFR inhibitors (erlotinib and gefitinib) with a wild-type
    Methods: We performed functional, biochemical, and immunohistochemistry studies.
    Results: We demonstrated good efficacy of MEN1611 in NSCLC devoid of
    Conclusions: Overall, this preclinical study indicates that the inhibitor could be a candidate for the treatment of NSCLC with an erlotinib/gefitinib-resistant phenotype and constitutive activation of the PI3K/AKT pathway, a phenotype mimicked by our model system.

    Abstract Background: Revision of a failed total hip arthroplasty (THA) poses technical challenges. The use of primary stems for revision can be advantageous for maintaining bone stock and reducing complications: small case series have reported promising results in the short-term to mid-term follow-up. The aim of this study was to evaluate the long-term clinical and functional results and survivorship of a consecutive series of THA femoral component revisions using a conical primary cementless stem (PCS).
    Methods: Ninety-four stem revisions with a preoperative Paprosky I or II defect were analyzed at an average follow-up of 12.7 ± 5.4 years. Aseptic loosening was the reason for revision in 92.5% of cases. Twenty patients were lost to follow-up. Two subgroups were created: Group 1 (n = 59) underwent isolated stem revision; Group 2 (n = 15) underwent complete THA revision. All were evaluated preoperatively and postoperatively based on the Harris Hip Score (HHS), the Western Ontario and McMaster Universities Index (WOMAC) score, and the visual analog scale for pain (VAS). Residual trochanteric pain and length discrepancies were recorded. Radiographic evaluation included signs of osteolysis, subsidence, loosening, and heterotopic ossification.
    Results: PCS survivorship was 100% at 5 years and 95.9% at 10 years. Overall, significant postoperative improvements (P < .01) were observed on the HHS (44.3 vs 86.9), WOMAC (42.8 vs 82.8), and VAS (7.0 vs 3.0). Postoperative scores on all scales were higher for Group 1 (P < .01). Three patients (4.1%) underwent further stem revision. Demarcation lines (1 mm) were found in 12 (16.2%) patients and significant heterotopic ossifications in 22 (29.7%).
    Conclusion: The use of PCS for stem revision in failed THA with a limited femoral bone defect is a reliable option for both isolated stem revision and concomitant cup revision in well-selected patients.

    Abstract Following insults or injury, microglia cells are activated contributing to the cytotoxic response or by promoting an immune-mediated damage resolution. Microglia cells express HCA2R, a hydroxy carboxylic acid (HCA) receptor, which has been shown to mediate neuroprotective and anti-inflammatory effects. In this study we found that HCAR2 expression levels were increased in cultured rat microglia cells after Lipopolysaccharide (LPS) exposure. In a similar fashion, the treatment with MK 1903, a potent full agonist of HCAR2, increased the receptor protein levels. Moreover, HCAR2 stimulation prevented i) cells viability ii) morphological activation iii) pro/anti-inflammatory mediators production in LPS-treated cells. Likewise, HCAR2 stimulation reduced the proinflammatory mediators mRNA expression induced by neuronal chemokine fractalkine (FKN), a neuronal derived chemokine activating its unique receptor, chemokine receptor 1 (CX3CR1) on microglia surface. Interestingly, electrophysiological recordings in vivo revealed that MK1903 was able to prevent the increase of the nociceptive neurons (NS) firing activity mediated by the spinal FKN application in healthy rats. Collectively, our data demonstrate that HCAR2 is functionally expressed in microglia, by showing its capability to shift microglia toward an anti-inflammatory phenotype. Moreover, we indicated the contribute of HCAR2 in the FKN signaling and suggested a possible HCAR2/CX3CR1 functional interaction. This study paves the way for further investigations aimed at understanding the role HCAR2 as potential target in neuroinflammation-based CNS disorders. This article is part of the Special Issue on "The receptor-receptor interaction as a new target for therapy".

    Abstract In the context of the European Joint Action on Vaccination, we analyzed, through quantitative and qualitative methods, a random sample of vaccine-related tweets published in Italy between November 2019 and June 2020, with the aim of understanding how the Twitter conversation on vaccines changed during the first phase of the pandemic, compared to the pre-pandemic months. Tweets were analyzed by a multidisciplinary team in terms of kind of vaccine, vaccine stance, tone of voice, population target, mentioned source of information. Multiple correspondence analysis was used to identify variables associated with vaccine stance. We analyzed 2,473 tweets. 58.2% mentioned the COVID-19 vaccine. Most had a discouraging stance (38.1%), followed by promotional (32.5%), neutral (22%) and ambiguous (2.5%). The discouraging stance was the most represented before the pandemic (69.6%). In February and March 2020, discouraging tweets decreased intensely and promotional and neutral tweets dominated the conversation. Between April and June 2020, promotional tweets remained more represented (36.5%), followed by discouraging (30%) and neutral (24.3%). The tweets' tone of voice was mainly polemical/complaining, both for promotional and for discouraging tweets. The multiple correspondence analysis identified a definite profile for discouraging and neutral tweets, compared to promotional and ambiguous tweets. In conclusion, the emergence of SARS-CoV-2 caused a deep change in the vaccination discourse on Twitter in Italy, with an increase of promotional and ambiguous tweets. Systematic monitoring of Twitter and other social media, ideally combined with traditional surveys, would enable us to better understand Italian vaccine hesitancy and plan tailored, data-based communication strategies.
