AIM: To assess whether non invasive blood flow measurement by arterial spin labeling in several brain regions detects minimal hepatic encephalopathy. METHODS: Blood flow(BF) was analyzed by arterial spin labeling(ASL) in different brain areas of 14 controls, 24 cirrhotic patients without and 16 cirrhotic patients with minimal hepatic encephalopathy(MHE). Images were collected using a 3 Tesla MR scanner(Achieva 3T-TX, Philips, Netherlands). Pulsed ASL was performed. Patients showing MHE were detected using the battery Psychometric Hepatic Encephalopathy Score(PHES) consisting of five tests. Different cognitive and motor functions were also assessed: alterations in selective attention were evaluated using the Stroop test. Patients and controls also performed visuo-motor and bimanual coordination tests. Several biochemical parameters were measured: serum pro-inflammatory interleukins(IL-6 and IL-18), 3-nitrotyrosine, cGMP and nitrates+nitrites in plasma, and blood ammonia. Bivariate correlations were ***: In patients with MHE, BF was increased in cerebellar hemisphere(P = 0.03) and vermis(P = 0.012) and reduced in occipital lobe(P = 0.017). BF in cerebellar hemisphere was also increased in patients without MHE(P = 0.02). Bimanual coordination was impaired in patients without MHE(P = 0.05) and much more in patients with MHE(P < 0.0001). Visuo-motor coordination was impaired only in patients with MHE(P < 0.0001). Attention was slightly affected in patients without MHE and more strongly in patients with MHE(P< 0.0001). BF in cerebellar hemisphere and vermis correlated with performance in most tests of PHES [(number connection tests A(NCT-A), B(NCT-B)and line tracing test] and in the congruent task of Stroop test. BF in frontal lobe correlated with NCT-A. Performance in bimanual and visuomotor coordination tests correlated only with BF in cerebellar hemisphere. BF in occipital lobe correlates with performance in the PHES battery and with CFF. BF in cerebellar

OBJECTIVE: To verify the action of non-pharmacological interventions, whole body vibration exercise (WBVE) and auriculotherapy (AT) on the management of knee osteoarthritis (KOA) analyzing the handgrip strength (HS). METHODS: One hundred twelve participants with KOA were allocated in (a) WBVE group with peak-to-peak displacement of 2.5 to 7.5 mm, frequency from 5 up to 14 Hz, acceleration peak from 0.12 up to 2.95 g (2 d/weekly for 5 weeks),(b) AT group, points of both ears (Kidney, Knee-correspondent point and Shenmen) were stimulated with seeds,(c) WBVE + AT group and (d) respective control groups. HS was assessed in all the participants, in acute and cumulative responses. RESULTS: The intervention with WBVE alone and combined with AT improved (P < 0.05), in a cumulative response, the HS. CONCLUSION: WBVE alone or combined with AT might promote biological effects that interfere with the HS in individuals with KOA.
