Abstract
PURPOSE Rhabdomyosarcoma (RMS), the most common soft-tissue sarcoma in childhood, rarely affects adults, preferring male. RMS expresses the receptor for androgen (AR) and responds to androgen; however, the molecular action of androgens on RMS is unknown. METHODS Herein, testosterone (T) effects were tested in embryonal (ERMS) and alveolar (ARMS) RMS cell lines, by performing luciferase reporter assay, RT-PCR, and western blotting experiments. RNA interference experiments or bicalutamide treatment was performed to assess the specific role of AR. Radiation treatment was delivered to characterise the effects of T treatment on RMS intrinsic radioresistance. RESULTS Our study showed that RMS cells respond to sub-physiological levels of T stimulation, finally promoting AR-dependent genomic and non-genomic effects, such as the transcriptional regulation of several oncogenes, the phosphorylation-mediated post-transductional modifications of AR and the activation of ERK, p38 and AKT signal transduction pathway mediators that, by physically complexing or not with AR, participate in regulating its transcriptional activity and the expression of T-targeted genes. T chronic daily treatment, performed as for the hormone circadian rhythm, did not significantly affect RMS cell growth, but improved RMS clonogenic and radioresistant potential and increased AR mRNA both in ERMS and ARMS. AR protein accumulation was evident in ERMS, this further developing an intrinsic T-independent AR activity. CONCLUSIONS Our results suggest that androgens sustain and improve RMS transformed and radioresistant phenotype, and therefore, their therapeutic application should be avoided in RMS post puberal patients.

Abstract
In the last few years, molecular targeted therapies have replaced traditional cytotoxic chemotherapy in the fight against many cancers to the extent that our understanding of tumor biology has become more sophisticated. This shift has markedly changed adverse event profiles, compared to cytotoxic chemotherapy, affecting a diverse range of organ systems. Everolimus was approved by the FDA in 2011 for the treatment of progressive pancreatic NE tumors. It is an inhibitor of mammalian target of rapamycin (mTOR) and exhibits antitumor activity via disruption of various signaling pathways and it's used in the treatment of advanced renal cell cancer, breast cancer and neuroendocrine tumors (NET); it's used also as anti-rejection agent for transplantation but with lower doses for anti-rejection (1.5-3.0 mg/day) than for anti-cancer (5-10 mg/day) treatment. Metabolic side effects are the most frequent reported and will be discussed in this review.

Abstract
BACKGROUND Anorexia of ageing (AA) may be considered as a risk factor for frailty and has an important impact on quality of life, morbidity and mortality. METHODS A systematic review and a meta-analysis were performed to summarise the results from several trials on the effectiveness of treatments in AA, as associated with depression, sensory impairment of taste and smell, decreased appetite or early satiety, and disability. Eligible studies were required to report baseline and follow-up values, the mean change (∆-change) from baseline, and/or the mean difference among intervention groups versus control group, concerning food intake (kcal/daily) and/or nutritional outcomes, such as body weight, body mass index, albumin and Mini Nutritional Assessment. RESULTS The systematic review included 20 papers based on different therapeutic approaches concerning food intake and/or nutritional outcomes. The results of the meta-analysis indicate that the interventions for AA have an important impact on body weight [+1.59 kg; 95% confidence interval (CI) = 1.48-+1.71 kg; P < 0.001) and on energy intake (+56.09 kcal; 95% CI = -54.05 to +166.25 kcal; P = 0.32). Regarding secondary outcomes, it was not possible to meta-analyse the limited amount of data availab le. CONCLUSIONS The different variants of AA need to be defined because diverse therapeutic approaches are available. A more precise definition of the functional impairments associated with AA may allow a more correct decision about the most appropriate therapy to be prescribed. Moreover, this may allow for a more effective performance of the different therapeutic approaches once they are better targeted to the different scenarios of AA.

Abstract
PURPOSE To assess different aspects of bone damage in untreated adult patients with Klinefelter Syndrome (KS) before and during testosterone replacement therapy (TRT). METHODS Fifteen untreated hypogonadal men with KS and 26 control subjects (C) matched for age and BMI were recruited. Sex hormone levels were measured in all subjects. Lumbar spine (LS) and femoral (neck: FN and total hip: TH) bone mineral density (BMD), trabecular bone score (TBS), hip structure analysis (HSA) and fat measures (percentage of fat mass, android/gynoid ratio and visceral adipose tissue) were evaluated by DEXA. In KS patients, blood analysis and DEXA measurements were assessed at baseline and repeated yearly for three years during TRT. RESULTS Fat measures were significantly higher in KS than C (p < 0.01). In contrast, mean LS, FN and TH BMD were significantly reduced in KS compared to C (p < 0.01), while there was no difference in TBS. HSA revealed a significantly lower cortical thickness and significantly higher buckling ratio in KS compared to C at all femoral sites (p < 0.01). In KS patients, TRT significantly increased BMD at LS only, but did not improve TBS and HSA parameters. Fat measures were inversely associated with TBS values, and TRT did not influence this relationship. CONCLUSIONS In untreated hypogonadal men with KS, lumbar and femoral BMD was reduced, and femoral bone quality was impaired. Adiposity seemed to have a detrimental effect on lumbar bone microarchitecture, as indirectly evaluated by TBS. However, TRT failed to remedy these negative effects on bone.

Quantification of the Leydig cell compartment in testicular biopsies and association with biochemical Leydig cell dysfunction in testicular cancer survivors. Andrology 2018; 6:748-755.

Abstract
A simple histological method to evaluate the Leydig cell compartment is lacking. We aimed to establish such a method and to investigate if Leydig cell hyperplasia of the biopsy contralateral to the tumour-bearing testicle in patients with testicular germ cell cancer is associated with biochemical signs of Leydig cell dysfunction after long-term follow-up. A case group of 50 long-term testicular germ cell cancer survivors without human chorionic gonadotropin elevation, 10 testicular germ cell cancer patients with elevated human chorionic gonadotropin and 10 controls without testicular malignancy were included. For each subject, 2-4 representative sections from their testicular biopsies were selected for analysis. Using the image processing program ImageJ (V.1.48, NIH), an area with a minimum of 50 tubules was selected and delineated (total selected area) and the total Leydig cell area was calculated by adding up every delineated Leydig cell group within the total selected area. Four different methods were tested for the ability to quantify the Leydig cell compartment. In the 50 testicular germ cell cancer survivors, associations between the area of the Leydig cell compartment and serum levels of testosterone and luteinising hormone were investigated using linear regression analysis. The Leydig cell compartment was best quantified by the total Leydig cell area/total selected area index, which was significantly larger in the human chorionic gonadotropin-positive patients than in controls (P = 0.00001). In the 50 human chorionic gonadotropin-negative testicular germ cell cancer survivors, increasing total Leydig cell area/total selected area was significantly associated with decreased levels of total testosterone and decreased total testosterone/luteinising hormone ratio after a median of 9-year follow-up. In conclusion, a new simple method, total Leydig cell area/total selected area, was established to estimate the Leydig cell compartment in testicular biopsies. The index identified Leydig cell hyperplasia in the contralateral biopsy in patients with testicular germ cell cancer, and it was associated with long-term biochemical Leydig cell dysfunction. Although in testicular germ cell cancer survivors, the clinical value is limited because the contralateral biopsies are not commonly available, we propose a closer andrological follow-up in any patient with an increased total Leydig cell area/total selected area index.

Abstract
BACKGROUND Sperm motility is an essential aspect of human fertility. Sperm contain an abundance of transcripts, thought to be remnants of mRNA, which comprise a genetic fingerprint and can be considered a historic record of gene expression during spermatogenesis. The aberrant expression of numerous genes has been found to contribute to impaired sperm motility; these include ROPN1 (rhophilin associated tail protein 1), which encodes a component of the fibrous sheath of the mammalian sperm flagella, and CABYR (calcium-binding tyrosine-(Y)-phosphorylation-regulated protein), which plays an important role in calcium activation and modulation. The aim of this study was to investigate ROPN1 and CABYR gene co-expression in asthenozoospermic semen samples in comparison with normozoospermic samples. METHODS We studied 120 semen samples (60 normozoospermic and 60 asthenozoospermic) from Caucasian patients attending our centre for an andrological check-up. Total RNA was extracted from purified spermatozoa with RNeasy mini kit. ROPN1 and CABYR mRNA expression was analysed using RT-qPCR. Continuous variables were described as means ± standard deviations. RESULTS ROPN1 and CABYR mRNA were simultaneously downregulated in asthenozoospermic in comparison with normozoospermic samples. There was also a positive correlation between total progressive motility and ROPN1 and CABYR gene expression and between total motile sperm number and ROPN1 and CABYR gene expression. CONCLUSIONS The results demonstrated downregulation of both ROPN1 and CABYR in asthenozoospermic samples and importantly, a positive correlation between the expression of the two genes, suggesting that ROPN1 and CABYR co-expression is a prerequisite for normal flagellar function and sperm motility.

Abstract
BACKGROUND Procollagen-III peptide (PIIINP) is a marker of fibrosis associated with increased cardiometabolic risk and progression of chronic liver diseases such as nonalcoholic fatty liver disease (NAFLD) and steatohepatitis; its association with type 2 diabetes mellitus (T2DM) has not been elucidated yet. The aim of this study was to investigate the relationship among circulating PIIINP levels, metabolic traits, and body fat distribution in subjects with T2DM with or without NAFLD. METHODS Data from 62 T2DM subjects recruited in our diabetes outpatient clinics at Sapienza University of Rome, Italy, were analysed. Participants underwent metabolic and inflammatory profiling (CRP, TNFα, IL-6, IL-8, WISP1, and adiponectin) and magnetic resonance imaging for diagnosing NAFLD on the basis of hepatic fat fraction (≥5.5%) and quantifying visceral and subcutaneous adipose tissue (AT) areas. Serum PIIINP was measured by human-PIIINP ELISA kits. RESULTS Higher PIIINP levels correlated with greater BMI and visceral AT area and were associated with systemic signatures of AT-associated inflammation-ie, higher WISP-1, IL-8, and lower adiponectin levels; conversely, PIIINP did not differ significantly between T2DM patients with or without NAFLD and were not associated with hepatic fat fraction, Fatty Liver Index, FIB-4, or transaminases. CONCLUSIONS Elevated circulating PIIINP levels specifically identify T2DM individuals with AT expansion and systemic proinflammatory profile suggestive for AT dysfunction; our results point toward a new role of PIIINP as a marker of fibroinflammation in dysmetabolic conditions, likely related to AT expansion.

Abstract
Adult-onset hypogonadism is a syndrome often underdiagnosed, undertreated, or incompletely explored. There are various reasons for this: firstly, undefined age range of men in whom testosterone levels should be investigated and then no definitive serum cutoff point for the diagnosis of hypogonadism; and finally, variable and non-specific signs and symptoms; men and physicians do not pay adequate attention to sexual health. All these factors make the diagnostic criteria for hypogonadism controversial. The evaluation of the clinical features and causes of this syndrome, its link with age, the role of testosterone and other hormone levels, and the presence of any comorbidities are all useful factors in the investigation of this population. The purpose of this manuscript, after an accurate analysis of current literature, is to facilitate the diagnosis of hypogonadism in men through the use of the CATCH acronym and a checklist to offer a practical diagnostic tool for daily clinical practice. A narrative review of the relevant literature regarding the diagnosis of late-onset hypogonadism or adult-onset hypogonadism was performed. PubMed database was used to retrieve articles published on this topic. A useful new acronym CATCH (Clinical features [symptoms] and Causes, Age, Testosterone level, Comorbidities, and Hormones) and a practical checklist to facilitate the evaluation of hypogonadism in aging men were used. The evaluation of the clinical features and causes of hypogonadism, the link with age, the role of Testosterone and other hormones, and the evaluation of comorbidities are important in investigating adult-onset hypogonadism. The CATCH checklist could be helpful for clinicians for an early diagnosis of both hypogonadism and associated comorbidities. We suggest the use of this acronym to advocate the investigation of declining testosterone in aging men.

Abstract
PURPOSE In this study, we evaluated the impact of risk factors for gestational diabetes on clinical/biochemical parameters and maternal/fetal outcomes. METHODS One hundred eighty-three (n 183) women (age 33.8 ± 5.5 years, 59% Caucasians, 41% non-Caucasians) with gestational diabetes were included in the study. Anamnestic information, anthropometric and laboratory parameters, and maternal and fetal outcomes at delivery were collected. RESULTS Insulin therapy prevalence was higher in Asians vs Caucasians (p = 0.006), despite lower pre-pregnancy BMI in Asians (p = 0.0001) and in pre-pregnancy overweight vs normal weight patients (p = 0.04). Insulin-treated patients had higher fasting OGTT glucose than patients on diet therapy (p = 0.003). In multivariate analysis, Asian ethnicity, age ≥ 35 years and pre-pregnancy BMI ≥ 25 kg/m2 were independent predictors of insulin therapy. Cesarean section occurred more in women aged ≥ 35 years than < 35 years (p = 0.02). Duration of pregnancy and age showed inverse correlation (r - 0.3 p = 0.013). Week of delivery was lower in patients ≥ 35 years vs patients < 35 years (p = 0.013). Fasting OGTT glucose was higher in overweight than in normal weight patients (p = 0.016). 1-h OGTT glucose was lower in obese vs normal weight (p = 0.03) and overweight patients (p = 0.03). Prevalence of prior gestational diabetes was higher in overweight/obese women (p = 0.002). CONCLUSIONS Ethnicity, age, and BMI have the heaviest impact on pregnancy outcomes.

Abstract
PURPOSE Patients with cystic fibrosis (CF) present with signs and symptoms that overlap with those of adult growth hormone deficiency (GHD) syndrome: loss of muscle mass, bone fragility and lower stress tolerance. In literature, the prevalence of GHD in pediatric CF patients is higher than general population, but these studies have been performed on children with growth delay. To our knowledge, there are no studies on adult patients. The aim of this paper is to evaluate GH-IGF1 axis in an adult CF population. METHODS Fifty clinically stable adult patients, 30 males; age 36 ± 2 years; BMI 21.39 ± 0.22 kg/m2 and FEV1 67 ± 4% were studied. Data regarding glycometabolic status and results of pituitary, thyroid, parathyroid, gonadal and adrenal function tests were recorded. All patients underwent a GH releasing hormone (GHRH) + Arginine stimulation test to confirm a GHD. RESULTS GHRH + Arginine test revealed the presence of GHD in 16 patients (32%); specifically 7 patients had a severe deficiency and 9 a partial deficiency. CONCLUSIONS Adult patients with CF may show GHD. These patients should be followed over time to assess if the GHD could impact the clinical progression of CF.

Abstract
PURPOSE Evaluation of the effects of an individualized home-based unsupervised aerobic training on body composition, physical and physiological parameters in female and male obese adults. METHODS Two hundred and twenty obese adults (age 47.9 ± 12.4 years; BMI 38.0 ± 7.2 kg/m2) entered the 4-month training program. Body composition, physiological and functional capacities were assessed pre- and post-intervention. All subjects were requested to perform unsupervised aerobic training with the intensity based on heart rate, walking speed and OMNI-RPE score corresponding to the individual ventilatory threshold for at least 5 days/week. RESULTS After 4-month study period, 40% of patients completed the protocol, 24% had high compliance (HC) (exercise ≥ 3 days/week), while 16% had low compliance (LC) to exercise prescription (exercise < than 3 days/week). In HC group, a significant improvement of body composition variables after training was performed. Moreover, oxygen uptake and metabolic equivalent at peak significantly increased after training. Six-minute walking test (6MWT) distance significantly increased while heart rate during 6MWT was significantly lower after training. No significant differences were found in LC group between pre- and post-intervention in all variables. Interestingly, gender does not influence the effects of training. CONCLUSIONS Our results indicate that subjects, independent of gender, with high compliance to the aerobic training based on a new individualized method can achieve a significant reduction in weight loss and also an improvement in physical and physiological parameters. This innovative personalized prescription could be a valuable tool for exercise physiologist, endocrinologists, and nutritionists to approach and correct life style of obese subjects.

Abstract
PURPOSE To investigate the association between fasting glucagon-like peptide 1 (GLP-1) levels and resting energy expenditure (REE), and respiratory quotient (RQ) in overweight and obese adults. METHOD Study participants were enrolled at the Dietetic and Metabolic Unit, University of Pavia, Italy. Inclusion criteria were age ≥ 25 and ≤ 45 years, and body mass index (BMI) ≥ 25 and ≤ 35 kg/m2. Diabetic subjects were excluded. Body composition was measured by dual-energy X-ray absorptiometry. REE was evaluated using indirect calorimetry, and RQ was calculated from respiratory gas exchanges. Fasting GLP-1, glucose, insulin and free fatty acid (FFA) levels, and 24-h norepinephrine urinary excretion were measured. Homeostasis model assessments of insulin resistance (HOMA-IR) and beta-cell function (HOMA-β) were calculated. RESULTS Thirty-seven participants were included (age 43.4 ± 1.6 years; BMI 30.6 ± 0.5 kg/m2). REE was not associated with fasting GLP-1 levels (p = 0.98) after adjustment for age, sex, fat-free mass (FFM), and fat mass (FM). Similarly, no association was observed between RQ and GLP-1 levels (p = 0.95), after adjustment for age, sex, and body fat. CONCLUSION In adults subjects with increased adiposity fasting, GLP-1 levels do not seem to play a role in the regulation of energy metabolism and in fuel selection.

Abstract
PURPOSE Tadalafil seems to ameliorate insulin resistance and glucose homeostasis in humans. We have previously reported that tadalafil targets human skeletal muscle cells with an insulin (I)-like effect. We aim to evaluate in human fetal skeletal muscle cells after tadalafil or I: (i) expression profile of I-regulated genes dedicated to cellular energy control, glycolitic activity or microtubule formation/vesicle transport, as GLUT4, PPARγ, HK2, IRS-1, KIF1C, and KIFAP3; (ii) GLUT4, Flotillin-1, and Caveolin-1 localization, all proteins involved in energy-dependent cell trafficking; (iii) activation of I-targeted paths, as IRS-1, PKB/AKT, mTOR, P70/S6K. Free fatty acids intracellular level was measured. Sildenafil or a cGMP synthetic analog were used for comparison; PDE5 and PDE11 gene expression was evaluated in human fetal skeletal muscle cells. METHODS RTq-PCR, PCR, western blot, free fatty acid assay commercial kit, and lipid stain non-fluorescent assay were used. RESULTS Tadalafil upregulated I-targeted investigated genes with the same temporal pattern as I (GLUT4, PPARγ, and IRS-1 at 3 h; HK2, KIF1C, KIFAP3 at 12 h), re-localized GLUT4 in cell sites positively immune-decorated for Caveolin-1 and Flotillin-1, suggesting the involvement of lipid rafts, induced specific residue phosphorylation of IRS-1/AKT/mTOR complex in association with free fatty acid de novo synthesis. Sildenafil or GMP analog did not affect GLUT4 trafficking or free fatty acid levels. CONCLUSION In human fetal skeletal muscle cells tadalafil likely favors energy storage by modulating lipid homeostasis via IRS-1-mediated mechanisms, involving activation of I-targeted genes and intracellular cascade related to metabolic control. Those data provide some biomolecular evidences explaining, in part, tadalafil-induced favorable control of human metabolism shown by clinical studies.

Abstract
PURPOSE The aim of the present study is to assess impairment of spermatogenesis induced by varicocele in, to our knowledge, the largest single-centre caseload available to date. MATERIALS AND METHODS We conducted a retrospective study on 4230 consecutive patients attending our Department for andrological outpatient assessment and preconception check-ups between 2011 and 2014. A total of 2113 patients had varicocele (Group V), while the remaining 2117 were selected as the control group (Group C). All patients were divided into age classes (<17, 18-28, 29-39 and ≥40 years), and Group V patients were classified as "low" (I-II) or "high" (III-IV) grade. RESULTS Varicocele patients had a higher mean height than controls, as well as lower BMI. There was also a statistically significant reduction in the concentration/mL and the total sperm number in Group V against Group C. When stratified by age, values for all semen parameters were significantly worse in the older than in the younger age classes in both Group V and Group C, except for concentration/mL and total sperm number in the 29-39 and ≥40 age classes in both groups. A multivariable logistic regression analysis showed that factors independently predicting the presence of varicocele were older age, higher BMI and smoking for more than 10 years. CONCLUSIONS Varicocele patients show worse semen parameters compared to controls, although their values were still within WHO reference limits. Semen quality is further worsened by increased age, grade and chronic smoking.

Abstract
INTRODUCTION Malnutrition is a frequent condition in the elderly especially in hospitals and in nursing homes, and even among the free-living elders the prevalence is not negligible (5-10%). Awareness towards malnutrition is still limited. The lack of time for nutritional assessment by the overcommitted healthcare personnel, including the general practitioners (GPs), may represent one possible explanation for limited recognition of malnutrition. Therefore, a self-administered instrument could be useful in raising alert on the GPs and allow early detection of malnutrition and early care provision. The aim of the present study was to analyze the validity of the Self-MNA that takes cue from the Mini Nutritional Assessment- Short Form (MNA-SF) and has been adapted to be self-administered by free-living elderly subjects. METHODS Participants were recruited from patients referring to the GP offices in Italy. Nutritional evaluation was performed through the administration of Full-MNA, MNA-SF and Self-MNA. The comorbidity level was assessed through the Cumulative Illness Rating Scale (CIRS). The level of difficulty in filling out the test was reported by the participants, and the time spent to complete the Self-MNA was also registered. RESULTS A total of 226 subjects, 125 women and 101 men (75.1 ±8 and 75.3 ± 8 years old, respectively; p=0.89) were enrolled, and 214 (94.7%) of them completed the Self-MNA. According with the Full-MNA test score, 8.4% of women and 3.5% of men were classified as malnourished, whereas 32.7% of women and 31.4% of men were at risk of malnutrition. Agreement between Self-MNA and Full-MNA, and Self-MNA vs. MNA-SF was classified as "moderate" (k = 0.476 and 0.496 respectively; p < 0.001). Self-MNA showed a fair predictive value compared to the Full-MNA and MNA-SF tests (76.6 and 79.9%, respectively) with a barely adequate sensitivity (70.9 and 75.4%, respectively). The analysis of the characteristics of FN (false negative: subjects who were considered at risk of malnutrition or malnourished at Full-MNA but not at Self-MNA) showed that the clinical and functional aspects of these subjects (age, comorbidity and severity, time necessary to complete the Self-MNA, decrease in food intake, severe illness in the past 3 months, dementia and depression, fluid intake, need for feeding assistance, arm and calf circumferences) were very similar to the characteristics of true positive subjects. Patients required 6.7 ± 4.5 minutes to complete the test and 25 subjects (11.7%) needed more than 10 minutes, up to a maximum of 30 minutes. Patients who stated a greater difficulty were older (79.8 ± 7 vs. 73.5 ± 7 years; p<0.001), they were more «malnourished» at Full-MNA (10.7 vs. 1,7%; p= 0.006) and clinical status was characterized by a higher severity index (1.72 ± 0.6 vs. 1.41 ± 0.4; p= 0.008). CONCLUSION In the present study we investigated the validity of the Self-MNA in a sample of free-living elderly subjects. The results obtained confirm the validity of the test that may represent a useful tool for the GPs, although some important limitations need to be considered, limiting its use in clinical practice.

Abstract
BACKGROUND Persistence is commonly considered a key factor for the successful management of osteoporosis and fragility fractures. Denosumab is the first biologic agent developed for the treatment of osteoporosis with satisfying data regarding the persistence with this therapy. AIM The purpose of this multicenter observational real practice study was to evaluate the persistence with denosumab treatment in post-menopausal women affected by osteoporosis. MATERIAL/SUBJECTS AND METHODS Women were recruited in four specialized centers for the management of osteoporosis in North, Center and South of Italy. We included women with a diagnosis of post-menopausal osteoporosis, aged >50 years, able to obtain a prescription according to the Italian reimbursement criteria in force during the study period for anti-osteoporotic pharmacological treatment. They initiated a treatment with subcutaneous denosumab (Prolia®) 60 mg/every 6 months between November 2011 and May 2016. Women who had received aromatase inhibitors were excluded. Patients were assessed at baseline and every 6 months for all treatment length. Persistence data were evaluated for a total of 36 months. RESULTS Eight hundred seventy women were enrolled; mean aged 70 years, with a mean body mass index of 24.8 ± 4.1 kg/m2. At the Dual-energy X-ray absorptiometry assessment, the mean lumbar spine T-score was -2.76 ± 1.14 standard deviations (SD) and the mean femoral neck T-score was -2.49 ± 0.80 SD. During the study, the total persistence was 91.4%. Total dropouts were 75 (8.6%), higher within the initial 6-month period of treatment. CONCLUSIONS Persistence to denosumab treatment in our observational real practice study was very high. These results suggest that factors such as frequency of visits, pharmacological schedule, and opportunity to call the doctor might play an important role in the persistence and adherence to treatment to obtain maximum therapeutic effect and avoid further fragility fractures.

Abstract
PURPOSE Autoimmune thyroiditis and its complications for the reproductive system are a growing problem. Selenium is a common ingredient in numerous food supplements recommended for thyroiditis and pregnancy. A fast, simple method to measure serum selenium concentration will improve knowledge of its pharmacokinetics and toxicity. AIM To validate a useful method to measure serum selenium concentration and to study selenium absorption and accumulation in a prospective interventional study of prolonged treatment. METHODS Thirty healthy volunteers received a single dose of L-selenomethionine one tablet (83 mcg) (Phase 1), a single dose of two tablets (Phase 2), and two tablets daily for 14 days (Phase 3). Total selenium and selenium time profiles were generated by serial sampling (T0, T3, T6, T12, and T24 hours after ingestion-Phases 1 and 2; and T0 and T24 hours-Phase 3). Selenium concentration was investigated by open-vessel acid digestion of small serum volumes followed by hydride generation atomic fluorescence spectroscopy analysis. RESULTS There was a significant increase in serum selenium concentration (mcg/L) in all treatment phases. Significantly increased levels were reached at T3 in Phase 1 (baseline: 76.5 ± 2.47; T3: 82.8 ± 3.28) and at T6 in Phase 2 (83.8 ± 3.46). They remained significantly increased at T12 in Phase 1 and T24 in Phase 2 (79.03 ± 2.69). There was significant selenium accumulation after prolonged intake (14 days) (102.13 ± 5.61). CONCLUSIONS Prolonged selenomethionine administration increases circulating blood selenium concentration and hydride generation atomic fluorescence spectroscopy enables its accurate quantification.

Abstract
PURPOSE Klinefelter's syndrome (KS) is associated with specific neurobehavioral features and personality traits. The aim of our study was to investigate fluid intelligence, personality traits and personality disorders (PD) and possible correlations with testosterone in a cohort of adult KS patients. METHODS We analyzed 58 adult KS patients with the classic 47, XXY karyotype. The Structured Clinical Interview for axis II disorders was used to assess DSM IV personality disorders. Personality traits were assessed using MMPI-2. Fluid intelligence was tested by using Raven's Standard Progressive Matrices (SPM) Test. Testosterone blood concentration was measured by CMIA. RESULTS PD prevalence was 31%. Four altered MMPI scales (Social Responsibility, Dominance, Ego Strength and Repression) were found in more than 40% of patients. Overcontrolled hostility and MacAndrew Alcoholism Scale-Revised scales were altered in the PD- group only. Biz-Odd Thinking and Post-Traumatic Stress Disorder scale were associated with the presence of personality disorder. The raw SPM score was 44 ± 10.8 without any significant correlation with testosterone. No significant difference in mean age, SPM raw score and MMPI score was observed between eugonadal, hypogonadal and treated patients. CONCLUSIONS Most KS patients had average fluid intelligence. PD prevalence was higher than in the general population. Testosterone was not correlated with fluid intelligence, personality traits or PD, but a reduction in marital distress was observed in treated patients. This could suggest that testosterone therapy can improve physical symptoms and this effect could also improve relationship abilities and wellness awareness.
