Abstract
As a result of incessant genetic discoveries and remarkable technological advancements, the availability and the consequent consumer's request for genetic testing are growing exponentially, leading to the development of a 'parallel' market, i.e. the direct-to-consumer (DTC) testing, also known as 'direct access testing' (DAT). Analogous to the traditional laboratory diagnostics, drawbacks of DTC testing might arise from any step characterising the total testing process, and include poor control of both appropriateness and preanalytical requirements, potential operation outside national or international regulation for in vitro diagnostic testing, little evidence of quality as well as the risk of transfer of genetic materials from the companies to other entities. Another important issue is the test panels offered to consumers, which are often based on preliminary, speculative or unsupported scientific information. Finally, the potential of this type of testing to generate anxiety or false reassurance should also be carefully considered. Although DTC testing carries some theoretical advantages (e.g. greater consumer autonomy and empowerment), solid clinical studies and costs vs. benefit analyses are needed to definitely establish whether DTC testing might be effective for decreasing the burden of diseases, delay their onset or modify their progression and therefore the clinical outcome.

Abstract
Anabolic Androgenic Steroids (AASs) are chemical and pharmacological derivatives of the male hormone testosterone which are widely used for increasing burst and sprinting activities in sports. Although AASs are thought to be transversal to the plurality of sports disciplines, they are principally misused by bodybuilders, weightlifters, shot, hammer, discus or javelin throwers, rugby and American football players as well as by swimmers and runners. AAS exert a kaleidoscope of effects on human biology, principally through the 5-α-reductase-mediated conversion into dihydrotestosterone, the aromatase-mediated conversion into female sex hormones, a competitive antagonism to the glucocorticoid receptors, the potential stimulation of erythropoietin secretion as well as psychoactive effects on the brain. The influence of AASs on physical performance is still undefined, since the large number of studies published so far have described discordant and often contradictory outcomes. Nevertheless, animal and human investigations support the hypothesis that the administration of AASs might increase lean body mass, muscle mass, and maximal voluntary strength especially in men, so that they would represent an appealing form of doping for increasing power capacity, sustaining intensive training periods and, last but not least, as a cosmetic muscle makeover. The aim of this article is to review the biochemistry, physiology and the ergogenic effects of AASs.

Abstract
INTRODUCTION The collection of diagnostic blood specimens for routine haematological testing (RHT) is traditionally performed with tourniquet. However, the transillumination devices based on cold near-infrared LEDs have been formerly proposed as a valuable tool for identifying reliable venous accesses, especially in patients with difficult or small veins, such as children. This study was aimed to evaluate whether a transillumination device can advantageously replace the use of the tourniquet during the procedure for collection of blood specimens for RHT and thereby eliminating the discomfort and risk of spurious results caused by excessive or prolonged venous stasis. METHODS Two hundred and fifty volunteers were divided into five groups (G1, G2, G3, G4 and G5) to compare the results of RHT between blood sample collected with transilluminator device (left arm) and with tourniquet application (right arm) for 30 s(G1), 60 s(G2), 90 s(G3), 120 s(G4) and 180 s(G5). RESULTS No significant increases were observed in any of the haematological parameters tested in G1 when compared with blood collected by the transilluminator device. From G2 to G5, significant increases were observed for the platelet count, red blood cell count, haemoglobin, haematocrit, white blood cell count, neutrophils, monocytes and eosinophils. From G3-G5, further increases were observed for lymphocytes. Clinically significant variations were, however, observed for basophils in G2; red blood cell count, haemoglobin, haematocrit and basophils in G3 and eosinophils in G3 only. CONCLUSION As such, considering that inappropriate use of the tourniquet is commonplace, we conclude that transillumination devices can represent a suitable tool to eliminate the venous stasis and to improve the quality of phlebotomy procedures.

Abstract
WHAT IS KNOWN AND OBJECTIVE There is a growing body of experimental and clinical evidence for the atherogenic and pro-thrombotic potential of Lipoprotein(a) [Lp(a)], as well as for its causative role in coronary heart disease and stroke. We comment on novel strategies for reducing Lp(a) levels. COMMENT Irrespective of the underlying biological mechanisms explaining the athero-thrombotic potential of this lipoprotein, most work has focused on the identification of suitable therapies for hyperlipoproteinemia(a). These include apheresis techniques, nicotinic acid and statins. None of these strategies have been shown to be definitely effective or convenient for the patient and new strategies are being attempted. Promising results are emerging with therapeutic interventions targeting the 'inflammatory pathways' by inhibition of Interleukin-6 (IL-6) signalling with natural compounds (e.g., Ginko biloba) or the IL-6 receptor antibody Tocilizumab. These may both lower Lp(a) and cardiovascular risk of the patients. Besides inhibiting platelet function, antiplatelet therapy with aspirin may also decrease the plasma concentration of Lp(a) and modulate its influence on platelets. WHAT IS NEW AND CONCLUSION We highlight the inadequacy of current approaches for lowering Lp(a) and draw attention to novel insights that may lead to better treatment.

Abstract
Despite the relatively low prevalence, ovarian cancer is the fifth leading cause of death from cancer among women. As such, an early diagnosis for establishing a timely surgical and/or chemotherapeutic treatment is essential for improving the outcome. The most reliable, but not always straightforward, approach to diagnose ovarian cancer relies on multiple, time-consuming and expensive investigative tools. These typically include clinical presentation (i.e., pelvic or abdominal pain, urinary frequency or urgency, increased abdominal size or bloating) with pelvic examination, transvaginal ultrasonography (US), and measurement of carbohydrate antigen 125 (CA125). Although the conventional pathway to develop and market a clinically useful biomarker is challenging, recent advances in genomic and proteomic technologies have led to the identification of previously unknown candidate markers of ovarian cancer. Some of these are currently under clinical validation. The human epididymis protein 4 (HE4) has recently been approved by the Food and Drug Administration for monitoring recurrence or progression of epithelial ovarian cancer. Nevertheless, reliable clinical evidence demonstrates that HE4, used alone or in combination with CA125, substantially improves the accuracy of screening and/or disease monitoring. This chapter will review the current knowledge on biologic and clinical applications of ovarian cancer biomarkers, with particular emphasis on the newly proposed marker, HE4.

Abstract
AIMS/HYPOTHESIS Non-alcoholic fatty liver disease (NAFLD) is associated with an increased prevalence of chronic kidney disease (CKD) and retinopathy in patients with type 2 diabetes. Information on this issue is lacking for type 1 diabetes. We evaluated whether NAFLD is associated with increased prevalence of retinopathy and CKD in type 1 diabetic patients. METHODS All type 1 diabetic patients (n = 202) who regularly attended our diabetes clinic and did not have any clinical evidence of cirrhosis or other secondary causes of chronic liver disease were studied. Main study measures were detection of NAFLD (by patient history and liver ultrasound), diabetic retinopathy (diagnosed by ophthalmoscopy) and CKD (defined as abnormal albuminuria or estimated GFR of < or =60 ml min(-1) 1.73 m(-2)). RESULTS The age- and sex-adjusted prevalence of diabetic retinopathy (53.2 vs 19.8%) and CKD (37.8 vs 9.9%) was markedly higher in patients with NAFLD than in those without (p < 0.0001). In multivariate logistic regression analysis, NAFLD was associated with prevalent retinopathy (adjusted OR 3.31, 95% CI 1.4-7.6, p = 0.005) or CKD (adjusted OR 3.90, 95% CI 1.5-10.1, p = 0.005). These associations were independent of age, sex, diabetes duration, HbA(1c), medication use and presence of the metabolic syndrome. CONCLUSIONS/INTERPRETATION Our findings suggest that ultrasound-diagnosed NAFLD is associated, independently of several confounding factors, with a higher prevalence of CKD and retinopathy in type 1 diabetic individuals.

Abstract
Mild hemophilia A (HA), defined by clinical features and factor VIII coagulant activity (FVIII:C) between 0.05 and 0.40 IU mL(-1), is characteristically distinct from severe HA. Indeed, although the molecular characterization of mild HA has permitted the identification of specific underlying mutations, its clinical phenotype is strikingly different from that of patients with a severe FVIII defect, where spontaneous hemorrhages or recurrent joint bleeding are usual manifestations. With aging, mild HA patients may develop complications (i.e. cancers and cardiovascular disorders), the management of which may prove challenging due to the concomitant bleeding tendency. Furthermore, the development of inhibitors provides an additional major complication in these patients, because it increases the severity of the bleeding phenotype and complicates their management. Standard management of mild HA includes the use of desmopressin and antifibrinolytic agents for minor bleeding episodes or surgical procedures, whilst major bleeding or surgery requires replacement therapy with FVIII concentrates. As regards treatment of patients with inhibitors, bypassing agents (i.e. activated prothrombin complex concentrates and recombinant activated FVII) have proven effective in the treatment of bleeding episodes, but as there are insufficient data to determine the optimal approach to immune tolerance induction in this group of patients, their optimal management remains controversial. Rituximab is a newer, promising therapeutic option for inhibitor eradication in such patients. Many aspects concerning mild HA remain to be clarified, including the molecular basis, the natural history and the optimal diagnostic and therapeutic strategies. Only large prospective studies will shed light on this condition.

Abstract
BACKGROUND AND AIMS Type 2 diabetes is one of the most important risk factor for the development of chronic kidney disease (CKD). Recently, it has been shown that lower high-density lipoprotein cholesterol (HDL-C) levels predicted the development of microalbuminuria in type 2 diabetic individuals. We have prospectively assessed the effects of plasma HDL-C levels on the incidence of CKD in a large cohort of type 2 diabetic patients. METHODS AND RESULTS We followed 1987 type 2 diabetic outpatients with normal or near-normal kidney function at baseline for 5 years for the occurrence of incident CKD defined as glomerular filtration rate < or = 60 mL/min/1.73 m(2) (as estimated by the abbreviated Modified Diet and Renal Disease Study equation). Cox proportional hazards models were used to examine the independent relationship between plasma HDL-C levels and incident CKD. During a median follow-up of 5 years, 11.8% (n=234) of participants developed incident CKD. In multivariate regression analysis, higher HDL-C levels were associated with a lower risk of incident CKD (multiple-adjusted hazard ratio 0.76; 95% coefficient intervals 0.61-0.96; p=0.025) independently of age, gender, body mass index, hypertension, smoking history, diabetes duration, hemoglobin A1c, plasma triglycerides, LDL-cholesterol, presence of diabetic retinopathy, baseline albuminuria, and current use of medications (anti-hypertensive, anti-platelet, lipid-lowering and hypoglycemic drugs). CONCLUSIONS Higher plasma levels of HDL-C are associated with a lower risk of incident CKD in a large cohort of type 2 diabetic adults independently of numerous confounding factors.

Abstract
Phenobarbital, a long-acting barbiturate, is generally considered to be a fairly safe and effective drug; however, hepatotoxicity is an infrequent but potentially fatal adverse effect and there is little information on the serum activity of liver enzymes in patients on stable, long-term monotherapy. The serum activity of alanine aminotransferase (ALT) and gamma-glutamyltransferase (GGT) are measured along with phenobarbital as part of the routine biochemical measurement in 128 consecutive adult out-patients on stable, long-term phenobarbital treatment. The control population consists of 2468 consecutive outpatients matched for age and gender. The patients on long-term phenobarbital therapy had significantly higher serum activities of ALT (27 IU/L versus 23 IU/L, P < 0.001) and GGT (79 IU/L versus 24 IU /L, P < 0.001). The prevalence of subjects with abnormal GGT values, but not ALT, was significantly higher than that in the control population. No significant differences were observed in either the mean activity or the prevalence of abnormal values of ALT or GGT between patients with suboptimal and therapeutic concentrations of the drug. These results suggest that chronic phenobarbital therapy may be associated with a clinically significant elevation of serum GGT activity. If confirmed, a specific GGT reference range should be adopted. Moreover, in those patients presenting with high serum GGT activity, it would not be necessary to reduce the dosage, discontinue the drug or change to a different anti-epileptic medication.

Abstract
Severity assessment of patients with haemophilia A (HA) is traditionally based on FVIII activity (FVIII:C). Clinical phenotype of HA patients often differs between individuals with the same FVIII:C determined with clotting and chromogenic assays. The aim of this study was to assess the influence of the FVIII:C on thrombin generation (TG) assay parameters both in vitro and ex-vivo postinfusion plasma. For in-vitro approach, influence of FVIII:C was evaluated on TG parameters in several dilutions of a normal plasma pool with commercial FVIII-depleted-plasma (FVIIIDP) and in others experiments, adding increasing amounts of different commercial FVIII concentrates (Fanhdi, Haemate-P, Hemofil-M and Kogenate Bayer) to FVIIIDP. In a series of 50 postinfusion samples, from HA patients of different severity, we assayed TG and FVIII:C (chromogenic and clotting). In vitro experiments, the 50% of maximum TG peak (TGMP) was achieved using only 5% FVIII:C and the TGMP was obtained with 40% of normal VIII:C. Impaired response compared with normal plasma was found in FVIIIDP using addition of increasing amounts of different commercial FVIII concentrates. An overall good correlation between the two FVIII assays was observed (y = 0.9115x - 0.273, r = 0.975, P < 0.001); TGMP and the Lag-Phase-Time (LPT) provided some discrepant results when compared with the total range of FVIII:C measurements. In contrast, correlations for TGMP, LPT and endogenous thrombin potential were improved in samples restricted to FVIII:C <5%. We conclude that TG parameters tentatively could be a tool to tailor the global haemostatic capacity in haemophilic patients.

Abstract
There is growing interest on haematological changes following elite and recreation sports. However, no information is available on leucocyte variations after an intermediate-distance run. Complete blood cell count was assessed on 17 trained, middle-aged males before a 21-km half-marathon, at the end and 3, 6, 24 h thereafter. Statistically significant variations by one-way analysis of variance were observed for all the parameters tested. Haematocrit, haemoglobin and red blood cells and platelet count increased significantly by the end of the run and returned to pre-run values 3 h thereafter. White blood cells, neutrophils, monocytes and basophils counts increased after the run, reached the peak at 3 h and returned to the baseline after 24 h. Conversely, the eosinophils count significantly decreased after the run, reached a nadir at 3 h and slowly returned to pre-run values at 24 h. The lymphocytes count significantly increased after the run, decreased 3 h thereafter and returned to pre-run values after 6 h. These results show that an intermediate-distance run, which is a popular form of recreational sports worldwide, is associated with transitory leucocytosis, neutrophilia, monocytosis and basophilia, but it also induces acute eosinopenia, all changes being completely reversed 24 h thereafter.
