    ABSTRACT: The current study investigated the neural correlates of voluntary motor control in 24 adult Gilles de la Tourette (GTS) patients. We examined whether imagination and the execution of the same voluntary movement - finger oppositions with either hand - were associated with specific patterns of activation. We also explored whether these patterns correlated with the severity of the syndrome, as measured by the YGTSS scale for motor tics. The presence of brain morphometric abnormalities was also assessed using voxel-based morphometry. Crucial to our experiment was the manipulation of the presence of an explicit motor outflow in the tasks. We anticipated a reduction in the ticking manifestation during the explicit motor task and brain activation differences between GTS patients and 24 age/gender-matched normal controls. The anticipated differences were all evident in the form of hyperactivations in the GTS patients in the premotor and prefrontal areas for both motor tasks for both hands; however, the motor imagery hyperactivations also involved rostral pre-frontal and temporo-parietal regions of the right hemisphere. The BOLD responses of the premotor cortices during the motor imagery task were significantly correlated with the YGTSS scores. In contrast, no significant brain morphometric differences were found. This study provides evidence of a different neurofunctional organisation of motor control between adult patients with GTS and healthy controls that is independent from the actual execution of motor acts. The presence of an explicit motor outflow in GTS mitigates the manifestation of tics and the need for compensatory brain activity in the brain regions showing task dependent hyperactivations.

    ABSTRACT: The aim of this study was to identify the relationship between metabolic effort, muscular damage/activity indices, and urinary amino acids profile over the course of a strenuous prolonged endurance activity, as a cycling stage race is, in order to identify possible fatigue markers. Nine professional cyclists belonging to a single team, competing in the Giro d'Italia cycling stage race, were anthropometrically characterized and sampled for blood and urine the day before the race started, and on days 12 and 23 of the race. Diet was kept the same over the race, and power output and energy expenditure were recorded. Sera were assayed for muscle markers (lactate dehydrogenase, aspartate aminotransferase, and creatine kinase activities, and blood urea nitrogen), and creatinine, all corrected for plasma volume changes. Urines were profiled for amino acid concentrations, normalized on creatinine excretion. Renal function, in terms of glomerular filtration rate, was monitored by MDRD equation corrected on body surface area. Creatine kinase activity and blood urea were increased during the race as did serum creatinine while kidney function remained stable. Among the amino acids, taurine, glycine, cysteine, leucine, carnosine, 1-methyl histidine, and 3-methyl histidine showed a net decreased, while homocysteine was increased. Taurine and the dipeptide carnosine (β-alanyl-L-histidine) were significantly correlated with the muscle activity markers and the indices of effort. In conclusion, the metabolic profile is modified strikingly due to the effort. Urinary taurine and carnosine seem useful tools to evaluate the muscle damage and possibly the fatigue status on a long-term basis.

    ABSTRACT: Aim of this study was to investigate RANKL and osteoprotegerin plasma concentrations in patients affected by disc herniation, the most common epiphenomenon of disc degenerative diseases, and in a matched cohort of healthy subjects and whether the expression of these markers was associated to a polymorphism of the vitamin D receptor gene. For this case-control study, 110 consecutive cases affected by lumbar disc herniation (confirmed by MRI) and 110 healthy age- and sex-matched controls were enrolled. Subjects affected by any other pathology were excluded. RANKL and osteoprotegerin were measured in plasma by immunoassays. The difference in these markers between cases and controls was assessed by t test. The correlation between osteoimmunological markers concentrations, anthropometrical variables, and the expression of the pathology was statistically assessed (Pearson's test) along with the association (Fisher's exact test) with the vitamin D receptor gene genotype, determined elsewhere. Despite comparable osteoprotegerin concentrations, cases, altogether or grouped for gender, express lower RANKL and, consequently, RANKL-to-osteoprotegerin ratio. While in cases RANKL and osteoprotegerin concentrations were independent from age and BMI, in controls they increased with age. Disc herniation was strongly associated with RANKL and the presence of the F allele of the VDR gene. Whether vertebral bone changes precede or follow cartilage deterioration in intervertebral disc degeneration is not known. Our results suggest a reduced bone turnover rate, associated to a specific genetic background, in patients affected by lumbar disc herniation which could be one of the favoring factors for disc degeneration.

    ABSTRACT: Evidence suggests that endurance and even recreational cycling may stimulate bone resorption; however, little is known about cartilage response to endurance cycling exercise. We investigated effort-dependent changes in bone turnover and cartilage biomarkers in blood and urine samples from elite cyclists during a 3-week stage race. Whole blood and urine samples were collected the day before the start of the race, at mid and end-race for serum and urinary CTx-I, NTx-I, PINP, COMP (only in serum), and CTx-II analysis by enzyme-linked immunosorbent assay. The values were corrected for plasma volume or creatinine excretion, respectively, and correlated with power output (corrected for body weight) and net energy expenditure. Bone marker concentrations in both serum and urine were slightly but significantly decreased. Among the cartilage degradation markers, only CTx-II was decreased, while COMP remained unchanged. The changes in bone and cartilage turnover indexes were correlated with the indexes of physical effort and energy consumption. Strenuous physical effort, in the absence of mechanical loading, slows bone metabolism and only minimally affects cartilage turnover. Since changes in plasma and urine volume, which normally occur in exercising athletes, can mask these effects, biomarker concentrations need to be corrected for shifts in plasma volume and urinary creatinine for correct interpretation of the data.

    ABSTRACT: the aim of this systematic literature review is to report clinical outcomes of reverse shoulder arthroplasty (RSA) used as a revision surgery following failure of the primary implant due to rotator cuff insufficiency. a systematic review was performed using the following key words: revision, shoulder, rotator cuff deficiency, outcome assessment, treatment outcome, complications. Studies eligible for inclusion in the review were clinical trials investigating patients in whom a primary shoulder arthroplasty implant with an incompetent rotator cuff was replaced with a reverse shoulder prosthesis. nine articles were identified and further reviewed. The results refer to a total of 226 shoulders that were treated with RSA as revision surgery. The patients in the studies had a mean age ranging from 64 to 72 years and the longest follow-up was 3.8 years. Improvements in function and reduction of pain were shown by many studies, but the mean Constant score ranged from 44.2 to 56. High complication rates (of up to 62%) were recorded, and a mean reoperation rate of 27.5%. RSA as revision surgery for patients with rotator cuff deficiency is a valid option, and often the only solution available, but it should be limited to elderly patients with poor function and severe pain. level IV, systematic review of level I-IV studies.

    ABSTRACT: Multiple myeloma (MM) is characterized by the progressive destruction of bone tissue due to the uncontrolled proliferation of the immunoglobulins. The detection of bone turnover markers (BTMs) may represent a non-invasive method to assess the bone involvement and to predict the risk of bone morbidity. This systematic review evaluates clinical utility of changes in BTMs levels in MM patients and their prognostic role. We searched Medline, Embase, WOS and Scopus. All eligible articles were examined and the risk of bias was evaluated. Results about PICP, PINP, ICTP, OC, CTX, NTX, RANKL and OPG were extracted. Weighted mean difference, risk ratio and hazard ratio were pooled. Thirty studies and more than 2500 patients were included in this systematic review. The majority of them (50%) used ELISA to quantify BTMs, 10 of them used RIA and only 4 did not report the information regarding the type of immunoassays. In MM patients, the concentration of NTX and ICTP increased, instead the concentrations of BAP and OC lowered when compared to healthy subjects. High levels of ICTP were predictive of bone events (RR 1.18) and they were associated to poor survival (HR 1.08). Most of the included studies were considered at high risk of bias, in fact the reporting of the results was often incomplete. Between-studies heterogeneity was high. BTMs measurement may be very useful in the management of MM patients, especially to evaluate the bone disease progression. They could help clinicians to identify patients at high risk of bone events and to opt for more appropriate therapy; nevertheless their high biological and analytical variability limit their implementation in clinical practice.

    ABSTRACT: Recently, the FokI polymorphism (rs2228570) in the vitamin D receptor gene (VDR) and conventional risk factors were associated with spine disorders in the Italian population, but without gender analysis. Two-hundred and sixty-seven patients (149 males, 118 females) with lumbar spine disorders were assessed by magnetic resonance imaging (MRI) and 254 (127 males, 127 females) asymptomatic controls were enrolled. The exposure to putative risk factors was evaluated and FokI polymorphism was detected by PCR-restriction fragment length polymorphism (PCR-RFLP). An association between lumbar spine pathologies and higher than average age; overweight; family history; lower leisure physical activity; smoking habit; higher number of hours/day exposure to vibration and more sedentary or intense physical job demand was observed in male patients. In contrast, in females, only higher age, overweight, family history and lower leisure physical activity were risk factors. FF genotype was a 2-fold risk factor to develop discopathies and/or osteochondrosis concomitant with disc herniation for both gender patients, while heterozygous Ff was protective for females only. In males only ff genotype was protective for discopathies and/or osteochondrosis and F allele was a 2-fold risk factor for hernia; discopathies; discopathies and/or osteochondrosis. Sex-related differences in voluntary behaviors, exposure to environmental risks and genetic background could be crucial for a gender-differentiated management of patients with spine disorders.

    ABSTRACT: Long-term effects of glucocorticoid treatment in humans induce bone loss and increase the risk of fracture in the skeleton. The pathogenic mechanisms of glucocorticoid-induced osteoporosis (GIOP) are still unclear. The GIOP and its effects have been reproduced in several animal models including Danio rerio (zebrafish) embryo. The treatment of adult fish with prednisolone (PN) has shown a dose-dependent decrease of mineralized matrix in the scales. Large resorption lacunae are characterized by single TRAP-positive cells which migrate to the margin of the scale merging into a multinucleated structures. The treatment with PN of cultured scales did not increase TRAP activity suggesting that the massive presence of osteoclasts in the resorption sites could be likely the result of a systemic recruitment of monocyte-macrophage precursors. We observed that treatment with PN induced a significant decrease of the alkaline phosphatase (ALP) activity in scale scleroblasts if compared with untreated controls. Then, we investigated the total mineral balance under prednisolone treatment using a time-dependent double live staining. The untreated fish fully repaired the resorption lacuna induced by prednisolone, whereas treated fish failed. The presence of osteoclast resorption fingerprints on new matrix suggested that the osteoclast activity counterbalances the osteodepositive activity exerted by scleroblasts. The treatment with PN in association with alendronate (AL) has surprisingly resulted in a significant decrease of TRAP activity and increase of ALP compared to PN-treated fish in biochemical and histological assays confirming the action of alendronate against GIOP in fish as well in humans. © 2015 The Authors.

    ABSTRACT: Purpose: 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. Methods: A total of 567 surgery reports of bilateral simultaneous (220) or unilateral (347) unicompartmental knee arthroplasties were analysed to collect study parameters. Information like the onset of complications and need for revisions were recorded by phone interview (at least two years after surgery). All surgeries were performed by the same orthopaedic surgeon, assisted by the same anesthesiologist. Results: Complication and revision rates, as well as the length of hospital stay were similar between the two study groups, while blood and haemoglobin losses, and consequently the use of transfusion of allogeneic and autologous blood units, were higher in the simultaneous bilateral group. Conclusions: Simultaneous bilateral unicompartmental knee arthroplasties could significantly reduce, if both joints are affected, the length of hospital stay and, therefore, patient management costs. At the same time, they do not lead to more frequent revisions or complications. The higher transfusion of allogeneic blood units could be reduced to unilateral surgery levels by the application of currently available protocols of autologous blood reinfusion.

    ABSTRACT: Aim: The impact of a soccer match on parameters related to protein catabolism and renal function was evaluated in male players. Methods: Blood was collected before and immediately after a 90 minutes soccer match from 19 athletes of two first division teams in Brazil. Red blood cells (RBC), hemoglobin (Hb), hematocrit (Ht), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC), ammonia, uric acid, urea and creatinine were analyzed. The modification of plasma volume was calculated, and biochemical values were corrected for this change. Urea/creatinine ratio and equations to estimate the glomerular filtration rate (eGFR) were used to assess kidney function. Results: Plasma volume decreased from pre- to post-match. Post-match values higher than the pre-match ones were observed for RBC, Hb and Ht, as a consequence of plasma volume decrease. An increase in ammonia and creatinine concentrations post-match in comparison with pre-match values was registered, without changes in uric acid and urea levels. A reduction in urea/creatinine ratio and in eGFR was observed post-match, suggesting a decrease of renal function. Conclusion: A soccer match induced alterations in parameters linked to renal function and protein metabolism in male athletes. Particular attention should be paid in the monitoring of the ammonia concentration as an indicator of metabolic activity and energy requirement during prolonged exercise.

    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: There is a common saying for expressing familiarity with something. It refers to our hands, and strangely enough, in English, one says to know something like the back of the hand, whereas in other cultures, for example, Italy, Spain and France, the same expression is with the palm. Previous behavioural data have suggested that our ability to visually discriminate a right from a left hand is influenced by perspective. This behavioural finding has remained without neurophysiological counterparts. We used an implicit motor imagery task in which 30 right-handed subjects were asked to decide whether a picture portrayed a right rather than a left hand during an fMRI event-related experiment. Both views (back and palm) were used, and the hands were rotated by 45° in 8 possible angles. We replicated previous behavioural evidence by showing faster reaction times for the back-view and view-specific interaction effects with the angle of rotation: for the back view, the longest RTs were with the hand facing down at 180°; for the palm view, the longest RTs were at 90° with the hand pointing away from the midline. In addition, the RTs were particularly faster for back views of the right hand. fMRI measurements revealed a stronger BOLD signal increase in left premotor and parietal cortices for stimuli viewed from the palm, whereas back-view stimuli were associated with stronger occipital activations, suggesting a view-specific cognitive strategy: more visually oriented for the back of the hand; more in need of the support of a motoric imagery process for the palms. Right-hand back views were associated with comparatively smaller BOLD responses, attesting, together with the faster reaction times, to the lesser need for neural labour because of greater familiarity with that view of the hand. These differences suggest the existence of brain-encoded, view-dependent representations of body segments.

    ABSTRACT: Purpose Arthroscopic techniques have become the gold standard in the operative management of several pathologic conditions of the shoulder. The purpose of this systematic review was to present the long-term outcomes following arthroscopic treatment of rotator cuff pathology. Methods A comprehensive literature review was performed to identify studies reporting clinical or structural results of arthroscopic rotator cuff repairs (ARCRs) at least 5 years after surgery. Results Ten articles were selected, which described 483 procedures. Study type, surgical approaches, complications, evidences of structural integrity of the repaired lesions, preoperative and postoperative functional scores are identified, analyzed and discussed. Satisfactory results are presented by all authors, and significant postoperative improvement is reported by all the studies with available preoperative data; 16 of 483 cases were re-operated. Conclusion Although high-level evidences are lacking, ARCR appears to be an effective and safe option to treat the symptoms of rotator cuff tears and to provide successful clinical results durable with time. Current evidences are insufficient to clearly define the relationship between structural integrity of repaired cuffs and long-term clinical outcome. The available data do not allow to draw conclusions regarding the long-term superiority of double-row versus single-row repairs. Level of evidence Review of level II, III and IV studies, Level IV.

    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.
