Abstract
Osteoarthritis (OA) represents an inflammation-driven injury of articular tissues, progressively leading to structural and functional joint impairment. The main symptom of OA is pain. Although it has been well established that OA represents a whole joint disease, the source of pain remains to be clarified. Nowadays, it has been well established that neurotrophines expression is evident in joints affected by OA. In addition, elevated NGF levels are found in the synovial fluid of patients with inflammatory or degenerative rheumatic diseases, including OA, rheumatoid arthritis and spondylarthritis. Growing evidences indicate that blocking NGF signaling using an anti NGF agent (i.e. tanezumab) provides effective pain relief. This study analyzed the effects of NGF and BDNF on cultured human chondrocytes by evaluating and their effects on chondrogenesis, chondrocyte differentiation and cartilage degeneration through a microarray analysis. The whole transcriptome analysis performed in this study highlighted how NGF and BDNF could be able to induce a proinflammatory response in human chondrocytes. Moreover, NGF and BDNF treatments seems to be able to induce the activation of several genes involved in the OA pathogenesis as IL17AR, HLA-DRB1, GDF-15, NR1D1, MCF2L and TGF-Beta.

Abstract
Background:Electrocardiographic (ECG) abnormalities are described in 25-75% Systemic Sclerosis (SSc) cases and they are associated with other systemic manifestations as well as with a worse prognosis. There is an increasing need for clinical and laboratory biomarkers to ameliorate the diagnostic and therapeutic approaches to patients with ECG abnormalities, due to their actual low sensitivity and specificity. Adipokines are circulating proteins that appear dysregulated in SSc and leptin in particular is synthesized in response to inflammatory conditions and seems to play a proinflammatory and pro-fibrotic action in SSc. Interesting, many studies in the last years have underlined its role in the cardiac remodeling mechanisms and in the development of cardiac fibrosis in other chronic diseases.Objectives:Aim of our study is to evaluate the role of leptin in the development of cardiac rhythm disorders (CRD) during SSc. Furthermore, by the analysis of the clinical and demographical parameters of our SSc patients, we tried to define other possible features associated with increased serum leptin concentration.Methods:We included eighty-five SSc patients, fulfilling the 2013 ACR/EULAR classification criteria, attending the Regional Rare Disease Center of Policlinico Umberto I of Rome. Fifty presented significant CRD at non-invasive diagnostic techniques (12 Lead ECG, 24-hour Holter ECG). Demographic, clinical, conventional cardiovascular risk factors were examined; instrumental and laboratory assessments were obtained, together with ECG recordings. Thirty-five SSc patients without pathologic finding at ECG traces, matched for demographic and clinical features, were recruited as the control group. In all cases, after obtaining written informed consent, blood samples were taken to measure serum levels of leptin using an ELISA assay (Life Technologies-Italia).Results:The fifty SSc patients with CRD (mean age 51±15 years; F:M 41:9) had pulmonary fibrosis (PF) in 32 cases (64%) and a BMI >25Kg/m2in 22 (44%) while in the control group of thirty-five SSc patients (mean age 49±16 years; F:M 33:2) PF was found in 15 (43%) and a BMI >25Kg/m2in 9 (35%); We detected significantly higher median values of serum leptin in SSc patients with CRD compared to the control group (12027 pg/ml IQR 12314 versus 6392 pg/ml IQR 7103;p 0,0009). Additionally, SSc patients with a BMI> 25 kg/m2(31 cases) as well as those with PF (47 cases) showed a significantly higher median serum leptin levels compared to those with BMI <25 kg/m2(13161 pg/ml IQR 13610 versus 8187 pg/ml IQR 8255;p 0,0008) and those without PF (11740 pg/ml IQR 11940 versus 7616 pg/ml IQR 7855;p 0,0079).Conclusion:To our knowledge this is the first report on high serum levels of leptin in SSc patients with CRD that also confirms its increase in those cases with a BMI >25 kg/m2and with PF, according to scientific literature data. The role of leptin in the pathogenesis of SSc remains unclear although it is already known its involvement in the development of cardiac fibrosis during other chronic diseases. On the basis of these results we speculate on leptin involvement in the pathogenesis of CRD during SSc, although further studies are needed with larger cohort of patients.References:[1]Vacca A et al.

Abstract
BACKGROUND Reverse shoulder arthroplasty (RSA) in complex shoulder fractures is ever more frequently. This study compares clinical and radiologic results of patients with comminuted proximal humeral fractures (PHFs) treated with RSA, with and without tuberosities grafting. METHODS Between January 2009 and June 2014, 55 patients aged ≥65 years with 3- and 4-part PHFs were treated surgically. Patients' files and the hospital's digital database were reviewed retrospectively with at least 5-year of follow up. We constituted three groups according to the tuberosity consolidation: patients in whom the tuberosities showed anatomic consolidation (Group I) and patients either with secondary displacement of the tuberosities (Group II) or without tuberosity repair (Group III). RESULTS The 74% of the repaired tuberosities consolidated in anatomic position. Among range of motion (ROM), we reported that forward elevation, abduction and external rotation were significantly better in Group I than those in Group II-III. Furthermore, quick Dash score and Constant score showed more satisfied results in Group I. Regarding complications, not infection or instability were found in group I. On the other hand, in group II, we reported one patient with deep infection, leading to two steps surgery. In group III, we recorded two patients with instability required implant revision and one with deep infection treated by revision. CONCLUSION RSA showed satisfied results even at 5 year follow up. Preservation of the tuberosities in anatomic position improves active forward elevation and external rotation as well as patient satisfaction with less complications.

Abstract
Transfection is a process by which oligonucleotides (DNA or RNA) are delivered into living cells. This allows the synthesis of target proteins as well as their inhibition (gene silencing). However, oligonucleotides cannot cross the plasma membrane by themselves; therefore, efficient carriers are needed for successful gene delivery. Recombinant viruses are among the earliest described vectors. Unfortunately, they have severe drawbacks such as toxicity and immunogenicity. In this regard, the development of non-viral transfection vectors has attracted increasing interests, and has become an important field of research. In the first part of this review we start with a tutorial introduction into the biological backgrounds of gene transfection followed by the classical non-viral vectors (cationic organic carriers and inorganic nanoparticles). In the second part we highlight selected recent reports, which demonstrate that hybrid vectors that combine key features of classical carriers are a remarkable strategy to address the current challenges in gene delivery.

Abstract
Several techniques and different biological or artificial tissues have been proposed as graft to restore articular defects. However, among the numerous and heterogeneous procedures proposed over time, the current literature findings are not conclusive. The aim of the current study is to evaluate if human costal cartilage can be suitable as graft for restoring articular cartilage defects. Knee articular cartilage and costal cartilage samples were obtained respectively from patients that underwent anterior cruciate ligament reconstruction (samples from notch plasty) or knee joint replacement and ear reconstruction or rhinoplasty through rib graft. The samples were stained with hematoxylin eosin, safranine-O, Gomori paraldehyde-fuchsin and Von Kossa for light microscopy. Immunohistochemistry was performed using anti-collagen I, II, IV and anti-SOX9 antibodies. Furthermore, samples were analyzed by transmission electron microcopy (TEM). In both cartilage, the cells are arranged in quite similar layers and the matrix show the same hyaline appearance: presence of type II collagen and solphated glycosaminoglycans, and absence of type I collagen and SOX-9. The bigger difference between the two hyaline tissues is the presence of perichondrium that surrounds all the specimens of costal cartilage. It consists of two separate layers where the inner one seems to get thinner with aging. The results show that rib cartilage seems to be an adapt tissue as graft for articular cartilage repair from a histological point of view. However, to date its therapeutic potential remains to be clearly defined by animal and clinical studies.

Abstract
We report the first supramolecular stabilizers of the interaction between 14-3-3ζ and two of its effectors, Tau and C-Raf, which are involved in neurodegenerative diseases and proliferative signal transduction, respectively. These supramolecular ligands open up an opportunity to modulate functions of 14-3-3 with these effectors.

Abstract
Nerve growth factor (NGF) is involved in several joint pathologies. It has been demonstrated that its concentration increases in synovial fluid and tissue from arthritis. However, its role in joint homeostasis and pathophysiology still remain to be clarified. This study analyzed the effect of 200 ng/ml on cultured human ligamentocytes by evaluating cell proliferation, cell phenotype and gene expression. The MTT test excluded an influence on cell viability at 7 and 14 days. Regarding cell phenotype, we observed that NGF might promote the synthesis of COL1A1. On the other hand, real time PCR showed that NGF did not influence gene expression of COL3A1, FGF-BETA, IGF1, MMP2, MMP3, MMP9 and MMP13. However, COL1A1 gene was significantly upregulated in treated cell at 14 days. Our results suggest that NGF may have an anabolic effect on ligament. Additional investigations are necessary to determine how NGF may influence ligamentocytes..

Abstract
INTRODUCTION Tibial spine avulsion fractures are mostly a paediatric injury which appropriate treatment is currently debated in literature. The choice between conservative and surgical treatment is based on the radiographic classification of Meyers-McKeever. The most diffused surgical techniques involve either internal fixation devices (screws) or bone tunnels fixation with resorbable sutures. Today, a third option is represented by resorbable magnesium screws which could combine the best features of the two classical systems. Objective of this study is to investigate the efficacy of these new devices in the surgical treatment of tibial spine avulsions. MATERIALS AND METHODS Since 2014 we have seen seven patients with tibial eminence fracture. Patients underwent clinical and radiological examination (MRI, CT scan) before surgery. Only 3 patients that presented with a grade III or IV lesion were treated surgically with internal fixation with magnesium resorbable screws. In post-operative follow-up, functional recovery was evaluated at 1, 2, 4, 6 and 12 months, clinically and by X-ray. Lysholm and IKDC scores were submitted at 1, 2, 6 and 12 months. MRI was repeated at 6 and 12 months. RESULTS All three surgical patients showed progressive clinical and functional improvement during the follow-up period. The first case showed a quicker overall recovery rate, which might be due to the lower grade of the lesion. Radiographs and MRI evaluation showed regular healing of the injury. The devices appeared completely resorbed at the 6 months follow-up and replaced by newly formed bone at the 12 months follow-up. CONCLUSIONS The treatment of tibial spine avulsion fractures with arthroscopic reduction and internal fixation (ARIF) technique by magnesium resorbable screws seems to result in an excellent functional recovery without complications related to fixation devices, which were completely resorbed after 6 months and replaced by newly formed bone after 12 months. This new method could be considered as an alternative option to classic techniques by non resorbable fixation devices or bone tunnel fixation. Further studies are needed in order to evaluate the efficacy of these new devices in a wider group of patients.

Abstract
BACKGROUND AND PURPOSE The clinical manifestation of dystonic spasms in blepharospasm (BSP) patients may be heterogeneous. Whether the varying phenomenology of eyelid spasms becomes manifest sequentially during the course of the disease or aggregates in separate clusters according to different disease courses is still unclear. For this purpose, the clinical features in BSP patients were evaluated longitudinally over a 5-year period and also the blink reflex recovery cycle was tested in a subgroup of BSP patients. METHODS Sixty BSP patients were videotaped at time 0 and after approximately 5 years of follow-up. Two experts in movement disorders, who were blinded to the video order, reviewed the videotapes and scored the severity of BSP using the Blepharospasm Severity Rating Scale. Changes in the R2 recovery index were also evaluated in 18 patients twice, i.e. upon enrolment and at the follow-up. RESULTS The severity of BSP worsened significantly over the 5-year follow-up period owing to the appearance or the increased duration and frequency of prolonged spasms. It was also found that the blink reflex recovery cycle worsened at follow-up in comparison with the baseline. CONCLUSIONS This study shows that the disease progression of BSP is characterized by the appearance or worsening of prolonged spasms. Prolonged spasms are accompanied by changes in the excitability of brainstem interneurons. Aging-related effects may exacerbate the pathophysiological mechanisms underlying spasms.

Abstract
BACKGROUND Hypothyroidism, characterised by low/normal free thyroxine (FT4) and free triiodothyronine (FT3) with elevated thyroid-stimulating hormone (TSH), is a well-known complication of nephrotic syndrome (NS). This is a common feature of primary and secondary glomerular diseases and comprises loss of protein in the urine and increased urinary excretion of thyroid hormones and thyroxine- binding globulin. With a normal thyroid reserve, this scenario is associated with the development of subclinical hypothyroidism, with a slight increase in TSH and normal free fractions. However, with a low thyroid reserve the transition toward overt hypothyroidism is almost inevitable, affecting morbidity and mortality. As T4 replacement is a cheap and well-established treatment to achieve a stable hormone status in different types of thyroid deficiency, it is essential to recognise and appropriately treat this condition. CONCLUSION In this article we summarise the evidence on this nephro-endocrine disorder in humans and focus on diagnostic and therapeutic strategies.

Abstract
Cardiorenal syndrome (CRS) describes the concurrent failure of cardiac and renal function, each influencing the other. Malnutrition and cachexia frequently develop in patients with heart failure or kidney failure. However, no information is currently available on the prevalence of malnutrition in CRS patients. We studied CRS patients admitted to an internal medicine ward during a 5-month period and evaluated their clinical characteristics and nutritional status. Malnutrition risk was assessed by using the validated screening tool NRS-2002 whilst body composition was assessed by bioimpedance analysis and muscle function was measured by handgrip (HG) strength. Cardiac mass was also recorded. Length of stay, hospital readmission and 6-month mortality were registered. During the study period, 22 CRS patients were studied. Twenty patients were diagnosed with either CRS type 1 or CRS type 5. In CRS patients, fat-free mass showed a trend toward representing a protective factor for 6-month mortality (OR=0.904; p=0.06). Also, fat-free mass correlated with HG strength and cardiac ejection fraction. Malnutrition risk was diagnosed in 45% of the patients, whereas 8 patients met the definition of cachexia. Even without statistical significance, CRS patients with malnutrition had lower BMI (Body Mass Index) (p=0.038) and fat-free mass (p= n.s.). However, CRS malnutrition was associated to higher 6-month mortality (p= 0.05), and appears to negatively influence the outcome in CRS (OR= 9; p= 0.06). Our results show that malnutrition is prevalent in CRS patients and influences the clinical outcome. The assessment of nutritional status, and particularly body composition, should be implemented in daily practice of patients with CRS.

Abstract
Autonomic nervous system is involved in body weight regulation. Gastrointestinal manifestations of systemic sclerosis (SSc) can influence patients nutritional status and facilitate the development of proteinenergy malnutrition. The aim of the study is to assess the nutritional status of SSc patients and to explore its possible correlation with autonomic dysfunction using heart rate variability (HRV). We enrolled 19 SSc subjects and 19 healthy subjects as controls. Body mass index (BMI) and body surface area (BSA) were collected and recorded in all patients. HRV was measured and the domains of low frequencies (LF, index of the sympathetic modulation) and high frequencies (HF, index of the parasympathetic modulation) were recorded. As assessed by the LF/HF RATIO, sympathovagal balance is altered in SSc patients because of increased sympathetic modulation and reduced parasympathetic activity. BMI positively correlates with LF (r=0.57; p less than 0.01) and LF/HF RATIO during daytime (r= 0.46; p less than 0.05). Similarly, BSA positively correlates with LF (r= 0.51; p less than 0.05), LF day time (r= 0.53; p less than 0.05) and LF/HF RATIO night time (r=-0.51; p less than 0.05). In SSc patients the autonomic dysfunction is characterized by increased sympathetic modulation. We observed a correlation between autonomic dysfunction and nutritional status in SSc patients.

Abstract
Osteoarthritis is a whole-joint disease and its pathogenesis remains poorly understood. Recent evidence proposed the importance of the innate immune system as trigger of synovium inflammation following the degeneration of cartilage. Moreover, synovial mast cells (MCs) might be correlated with pain and disability reported by patients. Anti IgE therapy represents a new class of MCs stabilizing agent, licensed for people with asthma and chronic urticaria. Therefore, we studied if the stabilizing effect of anti IgE would improve the pain and disability in patients affected by knee osteoarthritis and atopic disease. This pilot study provides the first evidence that anti IgE treatment induces a short-term clinical improvement supporting the role of MCs in osteoarthritis.

Abstract
The risk of venous thromboembolism (VTE) is increased across the spectrum of chronic kidney disease (CKD), from mild to more advanced CKD, and typically characterizes nephrotic syndrome (NS). VTE risk in patients with kidney disease may be due to underlying hemostatic abnormalities, including activation of pro-thrombotic factors, inhibition of endogenous anticoagulation systems, enhanced platelet activation and aggregation, and decreased fibrinolytic activity. The mechanisms involved differ depending on the cause of the kidney impairment (i.e. presence of NS or CKD stage). Sex and gender differences, as well as, environmental factors or comorbidities may play a modulating role; however, specific sex and gender data on this topic are still rare. The aim of the present review is to discuss the VTE risk associated with impairment of kidney function, the potential mechanism accounting for it and the impact of sex differences in this clinical setting.

Abstract
OBJECTIVE Cardio-Renal Syndrome (CRS) is a condition, which is more frequently observed in clinical practice. The aim of this study is to explore nutritional status and intrarenal arterial stiffness in patients affected by CRS. PATIENTS AND METHODS 14 consecutive CRS patients, screened for anthropometry, biochemistry, nutritional and metabolic status underwent renal Doppler ultrasound and whole-body bioimpedance spectroscopy (BIS). RESULTS We found a positive correlation between phase angle (PA) and CKD-EPI and MDRD (p=0.011 and p=0.007), and between body mass index and renal resistive index (RRI) (p=0.002). Finally, we found a negative correlation between fat-free mass and RRI (p=0.024). CONCLUSIONS Body composition assessment may improve the care of patients with chronic kidney disease (CKD). Also, BIS may help identify changes in hydration status in CKD patients resulting as a significant predictor of mortality.

Abstract
Nerve growth factor (NGF) is involved in several joint diseases. It participates in nociception and neurogenic inflammation and its concentrations increase in synovial fluid and tissue from arthritis. However, data about its role in articular cartilage are scant and conflicting. This study analysed effects of different NGF concentrations on cultured human chondrocytes by evaluating cell proliferation, cell phenotype, and gene expression. The MTT test excluded an influence on cell viability. Alcian blue and S100 staining demonstrated that NGF may induce de-differentiation of the chondrocyte phenotype. Real-time PCR showed that NGF did not influence gene expression of type I, II and XI collagen, TGF-β, IGF-1 and metalloproteinase (MMP)-13, while it reduced the expression of MMP-3. These findings show that NGF may have uncertain effects in human chondrocytes. Further investigations by wider gene expression and protein synthesis analyses are required to determine how chondrocytes may be influenced by NGF.

Abstract
Primary Sjögrens syndrome (pSS) is a chronic autoimmune disease characterized by dry eyes, dry mouth, and other clinical manifestations. The most common extraglandular manifestation of pSS is articular involvement and to date their management is unclear. The aims of the current pilot study were to assess the safety and the outcomes of homologous platelet-rich plasma (HPRP) injections in pSS cohort affected by knee arthralgia/arthritis at short-term follow up. This pilot study provides the first evidence that HPRP injections are a safe treatment and induce a short-term clinical improvement. Although the lack of a control group, randomization and long-term follow up prevents the assessment of the real effectiveness of this treatment, further studies are needed to confirm these findings and to determine the mechanism of action, biological changes and disease-modifying properties of PRP.
