    Abstract Toxic metals in the environment are often remediated using sorption techniques, particularly in aquatic and drinking water systems. However, a review of over 30 published sorption studies in the past two years alone revealed that the use of filtration to separate sorbed from unsorbed metals do not take into account metal hydroxide and oxide formation, and thus likely produce erroneous results. We quantified the effect of filtration on the removal of metal oxide/hydroxides from solution using a 0.45 μm filter as a function of pH, initial metal concentration and ionic strength for As, Be, Cd, Cu, Cr, Pb and Zn. We found that even when the initial metal concentration was as low as 0.1 mg/L, up to 93% of metals in solution were removed and up to 100% removal was observed when the initial metal concentration was 5 mg/L at a pH of 7. If this was unaccounted for, precipitated metal oxide/hydroxide removed via filtration will be inaccurately attributed to metal sorption. Additionally, we demonstrate that speciation modeling can underestimate the pH at which insoluble metal species form and therefore can only be used to approximate metal precipitation, especially in complex matrices. Overestimating the sorption capacity of sorbent materials has major implications if these sorbents are used for the purification of drinking water or other vital environmental remediation efforts. We recommend sorption studies using filtration prepare the appropriate matrix-matched control samples to quantify potential metal oxide/hydroxide formation.

    Abstract Beryllium (Be) is a relatively rare element and occurs naturally in the Earth's crust, in coal, and in various minerals. Beryllium is used as an alloy with other metals in aerospace, electronics and mechanical industries. The major emission sources to the atmosphere are the combustion of coal and fossil fuels and the incineration of municipal solid waste. In soils and natural waters, the majority of Be is sorbed to soil particles and sediments. The majority of contamination occurs through atmospheric deposition of Be on aboveground plant parts. Beryllium and its compounds are toxic to humans and are grouped as carcinogens. The general public is exposed to Be through inhalation of air and the consumption of Be-contaminated food and drinking water. Immobilization of Be in soil and groundwater using organic and inorganic amendments reduces the bioavailability and mobility of Be, thereby limiting the transfer into the food chain. Mobilization of Be in soil using chelating agents facilitates their removal through soil washing and plant uptake. This review provides an overview of the current understanding of the sources, geochemistry, health hazards, remediation practices, and current regulatory mandates of Be contamination in complex environmental settings, including soil and aquatic ecosystems.

    Abstract Background: Our aim was to determine the effectiveness of a new surgical technique for olecranon fractures using a tension plate (TP) designed by the operating surgeon.
    Methods: We included patients with olecranon fractures treated between September 2010 and August 2013 in our study. Treatment involved a new implant and operative technique, which combined the most favourable characteristics of 2 frequently used methods, tension band wiring and plate osteosynthesis, while eliminating their shortcomings. The new method was based on the newly constructed implant.
    Results: Twenty patients participated in our study. We obtained the following functional results with our TP: median flexion 147.5° (interquartile range [IQR] 130°- 155°), median extension 135°/deficit 10° (IQR 135°-145°), median pronation 90° (IQR 81.3°-90°), median supination 90° (IQR 80°-90°). Implant-related complications were noted in 1 patient, and implants were removed in 3 patients. The mean functional Mayo elbow performance score was 94.8 (range 65-100). The removal of the implant was considerably less frequent in patients operated using the new method and implant than in patients operated using conventional methods at our institution (p < 0.001). Mean duration of follow-up was 8 months.
    Conclusion: Our TP for the treatment of olecranon fractures is safe and effective. Functional results are very good, with significantly decreased postoperative inconveniences and need to remove the implant. Less osteosynthetic material was used for TP construction, but stability was preserved.

    Abstract Language assessment has a crucial role in the clinical diagnosis of several neurodegenerative diseases. The analysis of extended speech production is a precious source of information encompassing the phonetic, phonological, lexico-semantic, morpho-syntactic, and pragmatic levels of language organization. The knowledge about the distinctive linguistic variables identifying language deficits associated to different neurodegenerative diseases has progressively improved in the last years. However, the heterogeneity of such variables and of the way they are measured and classified limits any generalization and makes the comparison among studies difficult. Here we present an exhaustive review of the studies focusing on the linguistic variables derived from the analysis of connected speech samples, with the aim of characterizing the language disorders of the most prevalent neurodegenerative diseases, including primary progressive aphasia, Alzheimer's disease, movement disorders, and amyotrophic lateral sclerosis. A total of 61 studies have been included, considering only those reporting group analysis and comparisons with a group of healthy persons. This review first analyzes the differences in the tasks used to elicit connected speech, namely picture description, story narration, and interview, considering the possible different contributions to the assessment of different linguistic domains. This is followed by an analysis of the terminologies and of the methods of measurements of the variables, indicating the need for harmonization and standardization. The final section reviews the linguistic domains affected by each different neurodegenerative disease, indicating the variables most consistently impaired at each level and suggesting the key variables helping in the differential diagnosis among diseases. While a large amount of valuable information is already available, the review highlights the need of further work, including the development of automated methods, to take advantage of the richness of connected speech analysis for both research and clinical purposes.

    Abstract Background: The vertebral hemangiomas are benign vascular lesions occurring in spine. Although uncommon, symptomatic vertebral hemangiomas can be painful and can limit daily activities. A number of methods have been used in the treatment of symptomatic and aggressive vertebral hemangioma, but none of them is optimal. Treatment with cement vertebroplasty showed very good results. This study aims to illustrate the validity of the treatment with cement vertebroplasty in patients with painful vertebral hemangiomas.
    Patients and methods: From January 2000 to January 2007, 24 patients were treated by percutaneous vertebroplasty because of hemangioma: 16 thoracic, 8 lumbar. There were 11 males and 13 females. The average age at the time of surgery was 48 years. All the patients complained of a pain syndrome resistant to continuing medication. All patients underwent X-ray examination, CT-scan and MR of the involved level preoperatively. A unipedicular approach under fluoroscopic guidance has been performed in all patients. All procedures have been carried out under the local anesthesia. The mean follow-up was 5.8 years.
    Results: In all the patients a successful outcome has been observed with a complete resolution of pain symptom. Extravertebral vascular cement leakage has been observed in 3 patients, without any clinical radicular syndrome onset due to the epidural diffusion. Clinical and radiological follow-up showed stability of the treatment and absence of pain in all patients.
    Conclusion: Percutaneous treatment with vertebroplasty for symptomatic vertebral hemangiomas is a valuable, less-invasive, and a quick method that allows a complete and enduring resolution of the painful vertebral symptoms without findings of the vertebral body's fracture.

    Abstract The patients with intensive pain caused by the vertebra body fracture were treated by application of low viscosity cement (LVC), (Vertebroplastic, DePuy) and high viscosity cement (HVC), (Confidence, DePuy,) into the body, by means of diascopy through unilateral transpendicular approach. Application of LVC was made in 75 patients, on 109 vertebrae, and HVC was applied in 12 patients on 14 vertebrae. Application of LVC was performed on 48 thoracic and 61 lumbar vertebrae and 5 thoracic and 9 lumbar vertebrae were stabilized with HVC. 43 patients were treated for malignancy and in 38 for osteoporosis. For LVC, preoperative VAS score was 8.32 and 2.23 (p < 0.00001) 24 hours after surgery, and it remained stable 3 month later. For HVC, preoperative VAS score was 7.99 and it was 2.5 (p < 0.00001) 24 hours after surgery and 3 months later. In the group of patients treated with LVC, there was 1 serious complication, a paraparesis caused by the leakage of cement into the spinal canal, which was partially recovered after decompression and rehabilitation treatment and 2 superificial infections with S. epidermidis which were cured by means of antibiotics. In 32 vertebrae (32) cement leakage extra ossal, either into vein plexus or intradiscal during surgery were noticed. When HVC was applied, intradiscal leakage occurred in one case only (8%). By means od Wilcoxon paired test a significant difference was found between the preoperative VAS, and the values immediately after surgery and 3 months later (Z = 7.52, p < 0.00001) when LVC was applied., and with HVC it was ( Z = 3.04, p < 0.00001), which indicates that the fast achieved pain reduction remained stable during the 3 month follow-up. The vertebroplasty is a safe and efficient surgical method in treatment of compressive vertebrae fractures which do not react to the conventional method of treatment. This method, when HVC is applied, shows significantly less complications related to cement leakage.

    Abstract Background & aims: In our modern society, there is a growing and increasing prevalence of overweight, obesity and eating disorders and young female subjects frequently ask for nutritional counselling. Resting energy expenditure (REE) is essential to provide a sound diet to subjects seeking nutritional support. We perform a critical selection of accurate and reliable prediction equations employed on normal-weight, overweight and obese young women.
    Methods: REE of 157 young women of Caucasian race (18-35 years)was measured with indirect calorimetry and was compared with the principal prediction equations (Harris and Benedict, Owen, Mifflin, WHO, Bernstein and Robertson and Reid). The statistical analysis used to compare measured and the predicted REE was paired t -test, +/-95% confidence interval and Bland and Altman method. The influence of weight loss on the prediction error was estimated in 31 subjects. An additional REE measurement was performed on patients who had lost >or=5% of the initial body weight due to a sound low-calorie diet.
    Results: The equations more reliable in our study are Owen's equation in normal-weight subjects, Bernstein's equation in overweight subjects and Robertson and Reid's equation in obese subjects. Weight was a significant variable according to the stepwise regression analysis resulting in the following equation: 542.2 + 11.5 kg;R(2) : 0.59. Weight loss decisively increased the overestimation of the equations and only Owen's equation maintained the error of prediction within acceptable limits.
    Conclusions: The equation of Owen in normal weight, Bernstein in overweight and of Robertson and Reid in obese subjects should be chosen when we have to predict REE in young women. Due to metabolic adaptation occurring during therapeutic or spontaneous energy restriction, we suggest to use Owen' s equation.

    Abstract Background: Eating disorders (EDs) affect an increasing proportion of young women in western countries. Psychometric questionnaires represent valuable tools to investigate various and critical areas directly involved in the pathogenesis of EDS and to support diagnosis and therapeutic decisions.
    Methods: 162 young women (16-35 years old) seeking diet therapy were recruited. We classified subjects in normal eating behaviour (NEB) (n = 87), binge eating disorder (BED) (n = 12) and bulimic EDNOS (Eating Disorders not Otherwise Specified) (n = 63). The SCOFF, Eating Attitudes Test (EAT 26) and Three Factor Eating Questionnaire (TFEQ) were administered. Body mass index (BMI) was utilised to assess the nutritional status. An analysis of the reliability and validity (sensitivity and specificity) of the SCOFF, EAT 26 and TFEQ was performed.
    Results: Body mass index (BMI) of NEB, BED and bulimic EDNOS was 27.7, 35 and 31.1, respectively. BED showed the highest values at the dishinibition, hunger and food preoccupation scales but conversely, they were the least restrained group. The SCOFF was significantly associated with the dishinibition (r = 0.31), hunger (0.31), dieting (r = 0.34) and food preoccupation scales (r = 0.34). The reliability analysis showed that the SCOFF, EAT 26 and TFEQ had a Cronbach alpha of 0.47, 0.85 and 0.75, respectively. The ROC curves identified cut off points of 3, 10 and 25 as the best compromise between specificity and sensitivity for the SCOFF, EAT 26 and TFEQ, respectively.
    Conclusions: The SCOFF is a valuable tool for the screening of abnormal eating behaviours but the diagnosis should be always confirmed and supported by the administration of other questionnaires and structured interviews. We have also confirmed the high reliability of the EAT 26 and TFEQ even though the utilisation of these questionnaires has generated some issues about their application in populations characterised by loss of control and overeating episodes.

    Abstract The behavioural factors that drive a normal weight woman to embark on a diet and to look for nutritional support in weight loss clinics are still not completely understood. A pilot cross-sectional study was carried out in 70 young (age range: 18-35 yr), normal weight women attending a weight loss clinic in South of Italy (Naples). They were compared to a population of 94 normal weight students (age range:17-23 yr) who had never attended a weight loss clinic. Subjects with eating disorders have been excluded. Weight and height were measured and body mass index (BMI) was calculated. Eating behaviour was assessed using a validated Italian version of the Eating Disorders Inventory (EDI) questionnaire. The two groups were matched for BMI (22.4 vs 22.1 kg/m2), smoking and physical activity. Students were more educated and less likely to be on a diet at the time of the study. Students had statistically significant lower scores for drive for thinness, body dissatisfaction, inadequacy and interpersonal disrupt. The bulimia scale was the only significant predictor (p<0.05) of BMI in the patients' group; body dissatisfaction (p<0.05) predicted BMI in the control group. This study has shown that weight concern and health awareness are not the only factors that lead a normal weight woman to look for nutritional counselling but there is an underlying substrate of psychological and social distress behind the request, which should be properly assessed before starting any nutritional therapy in the clinical practice.
