ABSTRACT

Heavy metal levels appear to be associated with low bone mineral density (BMD) and the consequent osteoporosis risk, but the relationship with the disease has not been clearly defined. The altered expression pattern of numerous genes, including detoxifying genes, seems to play a pivotal role in this context, leading to increased susceptibility to several diseases, including osteoporosis. The purpose of this study is to analyse circulating heavy metals levels and the expression of detoxifying genes in osteoporotic patients (OPs, n = 31), compared with healthy subjects (CTRs, n = 32). Heavy metals concentration in plasma samples was determined by Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and the subsequent expression analysis of NAD(P)H quinone dehydrogenase 1 (NQO1), Catalase (CAT), and Metallothionein 1E (MT1E) genes in Peripheral Blood Mononuclear Cells (PBMCs) was assessed by real-time polymerase chain reaction (qRT-PCR). Copper (Cu), mercury (Hg), molybdenum (Mo) and lead (Pb) were found to be significantly higher in the plasma of OPs compared to CTRs. Analysis of the expression levels of detoxifying genes showed a significant decrease in CAT and MT1E in OP group. In addition, Cu correlated positively with the expression levels of both CAT and MT1E in CTRs group and MT1E in OPs. This study shows an increased circulating concentration of certain metals combined with an altered expression pattern of detoxifying genes in OPs, highlighting a novel aspect to be investigated in order to better characterize the role of metals in the pathogenesis of osteoporosis.

ABSTRACT

Frailty fractures place a significant socioeconomic burden on the health care system. The Italian Society of Orthopaedics and Traumatology (SIOT) is proceeding to fracture liaison service (FLS) model accreditation in several Italian Fracture Units (FUs), which provides a multidisciplinary approach for the management of the fragility fracture patient. INTRODUCTION: Osteoporosis and the resulting fragility fractures, particularly femoral fractures, place significant socioeconomic burdens on the health care system globally. In addition, there is a general lack of awareness of osteoporosis, resulting in underestimation of the associated risks and suboptimal treatment of the disease. The fracture liaison service (FLS) represents an exemplary model of post-fracture care that involves a multidisciplinary approach to the frail patient through the collaboration of multiple specialists. The purpose of this article is to highlight the path undertaken by the Italian Society of Orthopaedics and Traumatology (SIOT) for the purpose of certification of numerous FLS centers throughout Italy. METHODS: SIOT is proceeding with international FLS accreditation in several Italian Fracture Units (FUs), following the creation of a model that provides specific operational and procedural steps for the management of fragility fractures throughout the country. FUs that decide to join the project and implement this model within their facility are then audited by an ACCREDIA-accredited medical certification body. RESULTS: The drafted FLS model, thanks to the active involvement of a panel of experts appointed by SIOT, outlines a reference operational model that describes a fluid and articulated process that identifies the procedure of identification, description of diagnostic framing, and subsequent initiation of appropriate secondary prevention programs for fractures of individuals who have presented with a recent fragility fracture of the femur. CONCLUSION: Accreditation of this prevention model will enable many facilities to take advantage of this dedicated diagnostic-therapeutic pathway for the purpose of fracture prevention and reduction of associated health and social costs.

ABSTRACT

BACKGROUND: The efficiency of the fast-track (FT) process in the management of patients in Emergency Departments is well demonstrated, but there is a lack of research focused on older adults. The aim of our study was to verify whether the FT process is efficient and safe for older adults admitted to ED. METHODS: Observational case-control single-centre study. RESULTS: Five hundred four cases and 504 controls were analysed. The mean age was 75 years, and there was a predominance of women. In total 96% of subjects were classified with a "less-urgent" tag. The length of stay was significantly lower in the fast-track group than in the control group (median 178 min, interquartile range 184 min, and 115 min, interquartile range 69 min, respectively, p < 0.001), as well as the time spent between the ED physician's visit and patient discharge (median 78 min, interquartile range 120 min, and median 3 min, interquartile range 6 min, respectively, p < 0.001). There weren't any increases in the number of unplanned readmissions within 48 h, 7 days and 30 days. CONCLUSIONS: The fast-track appears to be an efficient and safe strategy to improve the management of older adults admitted to the ED with minor complaints.

ABSTRACT

Fear of falling (FF) is a common problem in older persons. FF negatively affects the quality of life by generating anxiety, loss of confidence and of self-efficacy, and, ultimately, activity restriction and increased risk of falling. The FES-I and Short FES-I are two instruments developed to assess FF in older persons which have been already validated in some European countries. Our objectives are to develop the Italian version of FES-I and the Short FES-I and to validate them in older persons. The back translation protocol adopted by the ProFaNE group was used to translate both scales from English to Italian. Participants were 157 community-dwelling persons aged>65 years who underwent comprehensive geriatric assessment, including a structured interview concerning FF, and were administered the FES-I and the Short FES-I. Both scales were re-tested after 4 weeks in 151 persons. FES-I and Short FES-I had high internal validity and test-retest reliability. The Short FES-I is highly comparable with the FES-I. We conclude that the FES-I and the Short FES-I are excellent instruments to asses FF in Italian older subjects and they may be used in future research projects and clinical trials.

ABSTRACT

Inflammation is part of the normal host response to infection and injury. However, inappropriate inflammation contributes to several diseases, including inflammatory bowel disease (IBD) and rheumatoid arthritis (RA). Both conditions are characterized by the excessive production of inflammatory cytokines, arachidonic acid (AA)-derived eicosanoids, and other inflammatory agents (e.g., reactive oxygen species, adhesion molecules). By virtue of their anti-inflammatory action, omega-3 polyunsaturated fatty acids (PUFA) may be beneficial in inflammatory diseases. A large body of evidence supports a protective effect of omega-3 PUFA in experimental animal and ex-vivo models of Crohn's disease (CD), Ulcerative colitis (UC) and Rheumatoid arthritis (RA). Although fish oil supplementation in patients with IBD results in omega-3 PUFA incorporation into gut mucosal tissue and modification of inflammatory mediator profiles, the evidence of clinical benefits of omega-3 PUFA is weak. On the other hand, more convincing data support the efficacy of omega-3 PUFA in reducing pain, number of tender joints, duration of morning stiffness, use of non-steroidal anti-inflammatory drugs and improving physical performance in RA patients. In both IBD and RA further clinical trials with large sample size are needed to clarify the efficacy of omega-3 PUFA as a treatment.
