Prophylaxis of Venous Thromboembolism after Hospital Discharge in Internal Medicine: Findings from the Observational FADOI-NoTEVole Study.

BACKGROUND AND AIM: Post-discharge prophylaxis for venous thromboembolism (VTE) is a challenging issue in patients hospitalised in Internal Medicine Units (IMUs). The aim of this study was to evaluate the frequency and the factors associated with post-discharge prophylaxis for VTE in IMUs. METHODS: Multi-centre, retrospective study including consecutive patients who were admitted for any cause and discharged from an IMU. RESULTS: Overall, 3,740 patients (mean age 74.1 ± 15.7 years) were included in the study at 38 IMUs in Italy. At discharge, the percentage of patients receiving pharmacological thromboprophylaxis was 16.0% (20.1% after excluding patients treated with anticoagulants for indications other than VTE prophylaxis). At multivariable analysis, history of ischaemic stroke, hypomobility ≥ 7 days, central venous catheter, ≥ 10 versus ≤ 5 days of hospital stay, use of corticosteroids, cancer, history of falls, availability of a caregiver, infections and age were significantly associated with thromboprophylaxis, while an inverse correlation was observed with concomitant anti-platelet drugs and platelet count < 70,000/mm3. Patients with a Padua Prediction Score ≥ 4 versus < 4 and with an IMPROVE bleeding score ≥ 7 versus < 7 more frequently received prophylaxis at discharge (31.2% vs. 10.6%, p < 0.0001, and 25.7% vs. 19.6%, p = 0.028, respectively). CONCLUSION: In this study, one in five patients discharged from an Italian IMU received prophylaxis for VTE. The perceived thrombotic risk is significantly related to the use of prophylaxis.

The Association between Serum Cytokines and Damage to Large and Small Nerve Fibers in Diabetic Peripheral Neuropathy.

Diabetic peripheral neuropathy (DPN) is a frequent complication of type 2 diabetes mellitus (DM) and may involve small and large peripheral nerve fibers. Recent evidence suggests a role of cytokines in DPN. The paper is aimed at exploring whether the serum concentration of cytokines is associated with small and large nerve fiber function and with neuropathic pain (NP). We recruited a group of 32 type 2 DM patients who underwent serum cytokines (TNF-α, IL-2, IL-4, IL-6, and IL-10) dosage as well as electrodiagnostic and quantitative sensory testing (QST) assessment to explore damage to large and small nerve fibers. Raised serum levels of IL-6 and IL-10 correlated with markers of large nerve fiber sensory and motor axonal damage. Raised IL-10 serum level was associated with signs of motor nerve demyelination. No differences were found in pain characteristics and electrodiagnostic and QST markers of small nerve fiber function in relation to cytokines serum levels. IL-6 and IL-10 serum levels were associated with large nerve fiber damage but not to small fibers function or NP. IL-6 and IL-10 cytokines might play a role in the pathogenesis of nerve fiber damage or represent a compensatory or neuroprotective mechanism.
