    ABSTRACT: The advantages of simultaneous bilateral procedures in joint arthroplasty have been widely described for in total joint replacements of both the hip and the knee. In contrast, unicompartmental knee arthroplasties, despite their effectiveness in pain relieving and functional improvement, are underinvestigated in these terms. The purpose of this study is to assess the possible benefits and risks of bilateral simultaneous knee replacements, in comparison with unilateral procedures.

    ABSTRACT: The intervertebral disc (IVD) presents a limited self-repair ability and cell-based therapies have been suggested to prevent or treat IVD lesions. Fibrin-based scaffolds as cell carriers are promising candidates in IVD tissue engineering thanks to their ability to be easily delivered into the defect and to adapt to the lesion shape, to support/retain the injected cells into the implantation site and to favor the production of a suitable extracellular matrix (ECM). We evaluated the in vitro and in vivo behavior of human nucleus pulposus (NP) and annulus fibrosus (AF) cells in a clinical grade collagen-enriched fibrin that has never been tested before for orthopaedic applications, comparing it with clinical grade fibrin. The survival of IVD cells seeded within fibrin or collagen-enriched fibrin and the ECM synthesis were evaluated by biochemical, immunohistochemical and transcriptional analyses, prior and after subcutaneous implantation of the gels in nude mice. After 28 days of implantation, NP and AF cells were still detectable within explants, produced tissue specific ECM, and showed a higher content of glycosaminoglycans and type I and II collagen compared to gels prior to implantation. Both fibrin gels, enriched or not with collagen, seemed to be suitable for the culture of AF cells, being able to support the homogeneous synthesis of type I collagen, characteristic of the native fibrocartilaginous AF tissue. Differently, fibrin alone was a more suitable matrix for NP culture, supporting the homogeneous deposition of glycosaminoglycans and type II collagen. In conclusion, our results suggest to combine AF cells with fibrin enriched or not with collagen and NP cells with fibrin alone to maintain the typical features of these cell populations, indicating these clinical-grade materials as viable options in cell-based treatments for IVD lesions.

    ABSTRACT: Osteocalcin (OC) is the main non-collagenous hydroxyapatite-binding protein synthesized by osteoblasts, odontoblasts, and hypertrophic chondrocytes. It has a regulatory role in mineralization and it is considered a marker of bone cell metabolism. Recent findings evidenced new extra-skeletal roles for OC, depicting it as a real hormone. OC shares many functional features with the common hormones, such as tissue-specific expression, circadian rhythm, and synthesis as a pre-pro-molecule. However, it has some peculiar features making it a unique molecule: OC exists in different forms based on the degree of carboxylation. Indeed, OC has three glutamic acid residues, in position 17, 21, and 24, which are subject to γ-carboxylation, through the action of a vitamin K-dependent γ-glutamyl carboxytransferase. The degree of carboxylation, and thus the negative charge density, determines the affinity for the calcium ions deposited in the extracellular matrix of the bone. The modulation of the carboxylation could, thus, represent the mechanism by which the body controls the circulating levels, and hence the hormonal function, of OC. There are evidences linking OC, and the bone metabolism, with a series of endocrine (glucose metabolism, energy metabolism, fertility) physiological (muscle activity) and pathological functions (ectopic calcification). Aim of this review is to give a full overview of the physiological roles of OC by collecting the newest experimental findings on this intriguing molecule.

    ABSTRACT: Saliva represents a low stress, not-invasively collected matrix that allows steroid hormone monitoring in athletes by reflecting type, intensity and duration of exercise. Whole body cryotherapy (WBC) consists of short whole-body exposures to extremely cold air (-110° to -140°C) which, despite being initially used to treat inflammatory diseases, is currently acquiring increasing popularity in sports medicine. Cryostimulation practice is now widely accepted as an effective treatment to accelerate muscle recovery in rugby players. The aim of this work was to study the changes of steroid hormones in saliva of rugby players after both 2 and 14 consecutive WBC sessions, in order to investigate the effects of the treatment on their salivary steroid hormonal profile. Twenty-five professional rugby players, belonging to the Italian National Team, underwent a 7-day cryotherapy protocol consisting of 2 daily sessions. Saliva samples were taken in the morning prior to the start of the WBC, in the evening after the end of the second WBC, and in the morning of the day after the last WBC session. The samples were analyzed for cortisol, DHEA, testosterone and estradiol using competitive enzyme-linked immunosorbent assays. Cortisol and DHEA showed a reduction already after the 2 WBC sessions of the first day; after 14 consecutive WBC sessions cortisol, DHEA, and estradiol levels decreased, while testosterone increased as did the testosterone to cortisol ratio. These results were confirmed by the fact that the majority of subjects showed variations exceeding the critical difference (CD). In conclusion, we found that WBC acutely affects the salivary steroid hormone profile, and the results are evident already after only one twice-daily session. Most significantly, after one-week of consecutive twice-daily WBC sessions, all the hormones were modified. This is the first experimental report that links changes in the hormonal asset to WBC.

    ABSTRACT: Fibrin is clinically employed as a versatile, safe and clinically applicable sealant and cell carrier. It has been able to support disc cells survival, to favor extracellular matrix production and to enhance the efficiency of cell transfer in the intervertebral disc (IVD). The aim of this review was to evaluate how fibrin has been used in vitro, in vivo and in clinical trials for IVD tissue engineering. Within the in vitro studies, disc cells were cultured in fibrin alone or combined with other materials and a difference in the behavior of nucleus pulposus (NP) and annulus fibrosus (AF) cells was sometimes reported, but, in general, the formation of fibrocartilaginous matrix was observed. Moreover, data concerning the fibrin long-term stability and its anti-inflammatory properties were found. Disc cells of human origin were never employed in combination with fibrin in vivo or in clinical trials. In vivo, disc degeneration models used to test the fibrin properties essentially involved NP injuries. The addition of cells, in particular if terminally differentiated, to the injected fibrin seemed to promote a more physiological matrix in comparison with fibrin alone. Important aspects should be further investigated in future studies such as the use of fibrin to treat AF lesions as well as the mechanical properties of the fibrin-based biomaterials and of the neo-formed tissue. Finally, in vivo studies and clinical trials with in situ injection of fibrin and human disc cells should be performed.

    ABSTRACT: Background. Intense training can lead to a pathophysiological change in serum concentration of a variety of biomarkers. Traditional biomarkers of cardiac injury are very useful in monitoring CVD patients, but in healthy subjects or athletes they cannot be informative enough about the cardiovascular risk, because in these cases their serum levels do not increase over the pathological limit. Therefore novel cardiovascular biomarkers are required in order to allow a better monitoring of sport performance, prediction of overtraining and diagnosis of sport-related cardiac injuries. Growth differentiation factor-15 (GDF-15) is emerging as a powerful cardiovascular injury risk indicator. In this study we investigate the effect of intense physical training of on the circulating levels of GDF-15 in rugby professional players. Methods. Serum GDF-15, Erythropoietin, IL-6, the cardiovascular parameter ST-2, NT-proBNP and routine hematological parameters were measured in a group of 30 rugby players before and after a session of intense training. Results. While ST-2, IL-6 and hsCRP displayed no significant changes after intense training, NT-proBNP and GDF-15 showed a significant increase, even without reaching the pathological level. Discussion. The measure of GDF-15 in professional rugby players could be a useful tool to monitoring their cardiovascular status during training and competition session in order to prevent the onset of collateral cardiovascular adverse event due to the intense training and, in the case of cardiac injury, it could possibly allow a very early diagnosis at the beginning of the pathogenic process.

    ABSTRACT: The purpose of this study is to demonstrate that inferior inclination of the glenosphere is a protecting factor from joint dislocation in reverse total shoulder replacement. The hypothesis is that an average of 10° of inferior inclination of the glenoid component would determine a significant inferior rate of dislocation as compared to neutral inclination. A retrospective case (dislocation)-control (stability of the implant) study was performed. Inclusion criteria were the homogeneity of the prosthetic model and availability of pre- and postoperative imaging of the shoulder, including antero-posterior and axillary X-ray views. Glenoid and glenosphere inclination were calculated according to standardized methods. Difference in between the angles determined the inferior tilt. Thirty-three cases fit the inclusion criteria. Glenoid and glenosphere inclination measured, respectively, 74.1° and 83.5°. The average tilt of the glenosphere measured 9.4°. The average tilt in stable patients was 10.2°. Tilt in patients with atraumatic dislocation measured, respectively, -6.9° (superior tilt) and 2.4°, while it was 8.3° for the patient with traumatic instability. The association between the tilt of glenosphere and atraumatic dislocation was significant. A 10° inferior tilt of the glenoid component in reverse shoulder arthroplasty is associated with a reduced risk of dislocation when compared to neutral tilt.

    ABSTRACT: Rotator cuff injuries are a common source of shoulder pathology and result in an important decrease in quality of patient life. Given the frequency of these injuries, as well as the relatively poor result of surgical intervention, it is not surprising that new and innovative strategies like tissue engineering have become more appealing. Tissue-engineering strategies involve the use of cells and/or bioactive factors to promote tendon regeneration via natural processes. The ability of numerous growth factors to affect tendon healing has been extensively analyzed in vitro and in animal models, showing promising results. Platelet-rich plasma (PRP) is a whole blood fraction which contains several growth factors. Controlled clinical studies using different autologous PRP formulations have provided controversial results. However, favourable structural healing rates have been observed for surgical repair of small and medium rotator cuff tears. Cell-based approaches have also been suggested to enhance tendon healing. Bone marrow is a well known source of mesenchymal stem cells (MSCs). Recently, ex vivo human studies have isolated and cultured distinct populations of MSCs from rotator cuff tendons, long head of the biceps tendon, subacromial bursa, and glenohumeral synovia. Stem cells therapies represent a novel frontier in the management of rotator cuff disease that required further basic and clinical research.

    ABSTRACT: Alterations in vitamin D homeostasis, mainly involving its nuclear receptor (VDR), could have a role in the pathophysiology of the spine. The association between VDR polymorphisms and spine disorders has been analyzed in different ethnic groups, focusing on the functional FokI polymorphism. However, so far, inconsistent findings were reported. The aims of this study were to evaluate, in the Italian white population, the VDR FokI polymorphism frequencies distribution in subjects with clearly defined lumbar spinal pathologies compared to asymptomatic controls and to analyze the interplay of genetic and conventional risk factors. Using a case-control design, 267 patients with spinal disorders and 220 asymptomatic controls were enrolled, evaluating their exposition to putative risk factors. Patients' clinical assessment was performed by Magnetic Resonance Imaging. FokI polymorphism (rs2228570) was detected by PCR-RFLP. Genotypes were designated by a lowercase letter (f allele, T nucleotide) for the presence of the restriction site and by a capital letter (F allele, C nucleotide) for its absence. Family history, higher age and BMI, exposure to vibration, physical job demand, smoking habit and lower practice of leisure physical activity were associated with spinal disorders. The FF genotype and F allele represented approximately 2-fold risk factors to develop discopathies and/or osteochondrosis concomitant with disc herniation, while f allele was protective. In conclusion, the link we observed between VDR FokI variants and specific lumbar spine pathologies suggests that spinal tissue degeneration is influenced by the genetic background. Future studies should evaluate the signaling pathways involving alterations in VDR and influencing the development and/or progression of spine disorders.

    ABSTRACT: Muscle traction and bone metabolism are functionally linked and co-regulated by a series of factors. Although a role for steroid hormones was hypothesized, a clear definition of the bone-muscle interconnection still lacks. To investigate this relationship, we studied bone metabolism, muscle activity, and salivary steroid hormones profile in relation with the physical effort across a cycling stage race, a model of effort in absence of load. Nine pro-cyclists were recruited; body weight and power output/energy expenditure were recorded. Diet was kept constant. Saliva was collected at days -1, 4, 8, 12, 14, 19, and 23; blood and urine were collected at days -1, 12, and 23. Salivary steroid hormones [cortisol, dehydroepiandrosterone (DHEA), testosterone, and estradiol], serum lactate dehydrogenase (LDH), aspartate aminotransferase (AST) and creatine kinase (CK) activities, plasma sclerostin, and urinary calcium and phosphorous were measured. Cortisol remained constant, testosterone decreased at day 4, and estradiol and DHEA firstly increased and then returned to basal levels. Hormone concentrations were not correlated with plasma volume shifts. LDH, CK, AST, sclerostin, and urinary calcium and phosphorous increased. DHEA and estradiol correlated with the physical effort and the bone-muscular markers. A relationship between muscle activity, in absence of load, and bone resorption emerged under a putative regulation by DHEA and estradiol.

    ABSTRACT: In spinal surgery, newly developed technology seems to play a key role, especially with the use of computer assisted image-guided navigation, giving excellent results. However, these tools are expensive and may not be affordable for many facilities. To compare the cost-effectiveness of pre-operative versus intra-operative CT guidance in spinal surgery. A retrospective economic study. A cost-effectiveness study was performed analyzing the overall costs of a population of patients operated on for lumbar degenerative spondylolisthesis, using an image-guided system (IGS) based on a CT scan. The population was divided into two groups, according to the type of CT data set acquisition adopted: Group I (IGS based on a pre-operative spiral CT scan), Group II (IGS based on an intra-operative CT scan - O-Arm(TM) system). The costs associated with each procedure were assessed through a process analysis: where clinical procedures were broken down into single phases and the related costs from each phase were evaluated. No benefits in any form have been received or will be received from commercial parties directly or indirectly related to the subject of this article. 499 patients met the criteria for this study. In total, 2,542 screws were inserted with IGS. Baseline data were similar for the two groups, as were hospitalization and complications. The surgical time was 119 ± 43 minutes in Group I and 92 ± 31 minutes in Group II. The full cost of the two procedures were analyzed: the mean cost, using the O-Arm(TM) system (Group II), was found to be € 255.83 (3.80%) less than the cost of Group I. Moreover, the O-Arm(TM) system was also used in other surgical procedures as an intra-operative control, thus reducing the final costs of radiological examinations (a reduction of around 550 CT scans/year). In conclusion, the authors of the study are of the opinion that the surgical procedure of pedicle screw fixation, using a CT-based computer-guidance system with support of the O-Arm(TM) system, allows a shortening of procedure time that might improve the clinical result. However, the present study failed to determine a clear cost-effectiveness with respect to other CT-based IGS.
