Abstract
Electrical injury can affect any system and organ. Central nervous system (CNS) complications are especially well recognised, causing an increased risk of morbidity, while peripheral nervous system (PNS) complications, neurourological and cognitive and psychological abnormalities are less predictable after electrical injuries. PubMed was searched for English language clinical observational, retrospective, review and case studies published in the last 30 years using the key words: electrical injury, electrocution, complications, sequelae, neurological, cognitive, psychological, urological, neuropsychological, neurourological, neurogenic, and bladder. In this review, the broad spectrum of neurological, cognitive, psychological and neurourological consequences of electrical trauma are discussed, and clinical features characteristic of an underlying neurological, psychological or neurourological disorder are identified. The latest information about the most recently discovered forms of nervous system disorders secondary to electrical trauma, such as the presentation of neurological sequelae years after electrocution, in other words long-term sequelae, are presented. Unexpected central nervous system or muscular complications such as hydrocephalus, brain venous thrombosis, and amyotrophic lateral sclerosis are described. Common and uncommon neuropsychological syndromes after electrical trauma are defined. Neurourological sequelae secondary to spinal cord or brain trauma or as independent consequences of electrical shock are also highlighted.

Abstract
Gait analysis is a significant diagnostic procedure for the clinicians who manage musculoskeletal disorders. Surface electromyography (sEMG) combined with kinematic and kinetic data is a useful tool for decision making of the appropriate method needed to treat such patients. sEMG has been used for decades to evaluate neuromuscular responses during a range of activities and develop rehabilitation protocols. The sEMG methodology followed by researchers assessed the issues of noise control, wave frequency, cross talk, low signal reception, muscle co-contraction, electrode placement protocol and procedure as well as EMG signal timing, intensity and normalisation so as to collect accurate, adequate and meaningful data. Further research should be done to provide more information related to the muscle activity recorded by sEMG and the force produced by the corresponding muscle during gait analysis.

Abstract
BACKGROUND B-thalassemia carrier state or thalassemia minor confers cardiovascular protection through favorable lipidemic and blood pressure profile. However, its impact on inflammatory status-a common denominator of the above conditions-has not been addressed. METHODS We investigated a wide range of inflammatory markers [white blood cell (WBC) count, homocysteine, C-reactive protein (CRP), serum amyloid A (SAA), fibrinogen, plasminogen, fibronectin, plasminogen activator inhibitor-1 (PAI-1), and uric acid] in a large cohort of 15 805 newly diagnosed hypertensive patients (8299 men, 7506 women); 626 of them (4.0%) had thalassemia minor. RESULTS The levels of WBC, homocysteine, CRP, SAA, fibrinogen, and PAI-1 were significantly lower in thalassemia minor patients, but not of plasminogen, fibronectin, and uric acid. In multivariate linear regression analyses, the lower values of WBC (<0.001), CRP (<0.001), homocysteine (<0.001), fibrinogen (<0.001), and PAI-1 (0.008), but not of SAA, were independently associated with thalassemia minor. The interaction between thalassemia minor and body mass index had a significant impact only on WBC and CRP (P for the interaction 0.010 and 0.005, respectively), whereas the interaction between thalassemia minor and sex had a significant impact only on fibrinogen (P for the interaction 0.007). CONCLUSION Thalassemia minor is followed by a favorable inflammatory profile that may contribute to the overall better cardiovascular health of the carriers.

Abstract
BACKGROUND Total knee arthroplasties (TKAs) using well-designed, fixed bearing prostheses, such as medial pivot (MP), have produced good long-term results. Rotating-platform, posterior-stabilized (RP-PS) mobile bearing implants were designed to decrease polyethylene wear. Sagittal and coronal plane TKA biomechanics are well examined and correlated to polyethylene wear. However, limited research findings describe this relationship in transverse plane. We assumed that although axial plane biomechanics might not be the most destructive parameters on polyethylene wear, it is important to clarify their role because both joint kinematics and kinetics in all 3 planes are important input parameters for TKA wear testing (International Organization for Standardization 14243-1 and 14343-3). Our hypothesis was that transverse plane overall range of motion (ROM) and/or peak moment show differences that reflect on wear advantages when compared RP-PS implants to MP designs. METHODS Two groups (MPs = 24 and RP-PSs = 22 subjects) were examined by using 3D gait analysis. The variables were total internal-external rotation (IER) ROM and peak IER moments. RESULTS No statistically significant difference was demonstrated between the 2 groups in kinetics (P = .389) or kinematics (P = .275). CONCLUSION In the present study, no wear advantages were found between 2 TKAs. Both designs showed identical kinetics at the transverse plane in level-ground walking. Kinematic analysis could not illustrate any statistically significant difference in terms of overall IER ROM. Nevertheless, kinematic gait pattern differences observed possibly reflect different patterns of joint surface motion or abnormal gait patterns. Thus, wear testing with various input waveforms combined with functional data analysis will be necessary to identify the actual effects of gait variability on polyethylene wear.

Abstract
The aim of this study was to determine cardiovascular (CV) risk factors (RFs) and target organ damage clustering in 21280 Greek hypertensives stratified by gender and age. Glycemic and lipid profile were determined, left ventricular mass index, estimated gromerular filtration rate (eGFR), 10-years CV risk according to Framingham risk score (FRS) and HeartScore (HS) were calculated. Only 10.2% of patients had no concomitant RFs, 53.1% had one (48.8% dyslipidemia, 3.4% smoking, 0.9% diabetes), 32.9% had two (26% dyslipidemia and smoking, 6.6% dyslipidemia and diabetes, 0.3% smoking and diabetes) and 3.7% had all four traditional RFs. Obesity was present in 30%, metabolic syndrome in 38%, low eGFR in 24% and left ventricular hypertrophy in 49%. Mean FRS risk was 35% for males, 24.1% for females whereas in high risk (>20%) were 68.7 and 50.7%, respectively (P<0.0001). Mean HS risk was 8.4% for males, 6.2% for females whereas in high risk (>5%) were 48.6 and 36.2%, respectively (P<0.0001). Age was correlated to pulse pressure, eGFR, left ventricular mass index and CV risk (P<0.0001). Ageing increased the risk difference between genders for total (P=0.001) but not for fatal events (P=nonsignificant). In conclusion, as RFs cluster in hypertensives, CV risk calculation should guide treatment decisions.
