Abstract
INTRODUCTION Pelvic organ prolapse is a multifactorial disease. Aim was to evaluate the effect of the whole surgical correction of pelvic floor on hydronephrosis due to severe prolapse. PATIENTS AND METHODS A retrospective case study on 250 patients presenting with severe uterovaginal prolapse was carried out. RESULTS Hydronephrosis was found in 32/234 (13.7 %). All patients underwent hysterectomy, vaginal apex axial suspension, posterior and anterior repair, vaginally. Prepubic TICT (Tension free Incontinence Cystocoele Treatment) was done in 38 cases (3 with hydronephrosis). Of the 32/234 (13.7 %) patients with hydronephrosis, 18/32 (56.25%) had complete resolution of hydronephrosis after treatment, 14/32 (43.75%) had a reduction of calico-pyelic dilatation, among them 8 patients had a second degree and 6 a first degree of hydronephrosis. CONCLUSIONS Vaginal-hysterectomy, axial apex suspension, anterior and posterior repair resulted in either complete resolution or improvement of hydronephrosis. Prepubic TICT did not interfere on mechanical obstruction and maintained postoperative continence in the event of occult Stress Urinary Incontinence (SUI).

Abstract
SW480 and SW620 colon carcinoma cell lines derive from primary tumour and lymph-node metastasis of the same patient, respectively. For this reason, these cells represent an ideal system to analyse phenotypic variations associated with the metastatic process. In this study we analysed SW480 and SW620 cytoskeleton remodelling by measuring the cells' mechanics and morphological properties using different microscopic techniques. We observed that different specialized functions of cells, i.e. the capacity to metastasize of elongated cells inside the primary tumour and the ability to intravasate and resist shear forces of the stream of cells derived from lymph node metastasis, are reflected in their mechanical properties. We demonstrated that, together with stiffness and adhesion between the AFM tip and the cell surface, cell shape, actin organization and surface roughness are strictly related and are finely modulated by colorectal cancer cells to better accomplish their specific tasks in cancer growth and invasion.

Abstract
Fetoplacental hydrops is the final stage of several pathological conditions in which the placenta and umbilical cord become edematous and the fetus develops an anasarcatic state characterized by an excessive accumulation of extravascular fluids in at least two serous cavities of the body. It is a common histological finding of stillbirth, characterized by the appearance of markedly edematous villi, suggesting an increased interstitial fluid accumulation. The recent improved knowledge of lymphangiogenesis and the availability of monoclonal antibodies selectively labeling lymphatic endothelium lead to the hypothesis that villous edema is essentially a lymphedema from defective lymphatic function following inadequate villous blood circulation. Lymphedema is a morphologic phenotype found by our research group in a 24-case series of stillbirths from different morbid conditions such as chromosomal aberrations, congenital malformations, inherited hemoglobinopathies, and prolonged perinatal severe anoxia. Unlike long-lived organs, the placenta is devoid of innervation by the autonomic nervous system; therefore, the vascular tone regulation and the peripheral perfusion are modulated by the expression of the angiotensin converting enzyme (ACE) in the vascular endothelia. This finding may suggest to the clinician to search for a more suitable therapy in case of mother's hypertension during pregnancy.

Abstract
BACKGROUND Hereditary tyrosinemia type 1 (HT1) is characterized by severe progressive liver disease and renal tubular dysfunction. NTBC therapy has revolutionized the management of HT1 but its effect on renal tubular function has so far been poorly investigated. The aim of this study was to describe the early effect of NTBC on renal tubular disease in patients with HT1. METHODS Five HT1 patients (age between 5 and 53 months) with different types of presentation were evaluated before and during the first 2 weeks of therapy with NTBC in a retrospective case analysis for phosphate metabolism and renal tubular function. RESULTS Before starting NTBC therapy, all children manifested signs of renal dysfunction which included hypophosphatemia, acidosis, reduced phosphate reabsorption, aminoaciduria, glycosuria (Fanconi syndrome), and variable degree of proteinuria. Some patients also presented increased urinary calcium/creatinine ratio and raised fractional excretion of sodium. Starting of NTBC therapy resulted in the rapid normalization of plasma phosphate within one week from its initiation in majority of patients and in all patients during the second week of therapy. TmP/GFR normalized in 48h, while the other markers of renal dysfunction showed an improving trend over 2 weeks. CONCLUSIONS NTBC is an efficient treatment for renal tubular dysfunction in HT1, allowing the return to normal function within a few weeks. Its early effect on renal tubular cells appeared to be very rapid, particularly in normalizing plasma phosphate and TmP/GFR. In our series of patients, the TmP/GFR resulted as the most reliable index of tubular function.

Abstract
Aboriginal Australians experience high rates of coronary heart disease (CHD) at an early age, highlighting the importance of effective secondary prevention. This study employed a two-stage process to evaluate CHD management in a regional Aboriginal Medical Service. Stage 1 involved an audit of 94 medical records of clients with documented CHD using the Audit and Best Practice in Chronic Disease approach to health service quality improvement. Results from the audit informed themes for focus group discussions with Aboriginal Medical Service clients (n=6) and staff (n=6) to ascertain barriers and facilitators to CHD management. The audit identified that chronic disease management was the focus of appointments more frequently than in national data (P<0.05), with brief interventions for lifestyle modification occurring at similar or greater frequency. However, referrals to follow-up support services for secondary prevention were lower (P<0.05). Focus groups identified psychosocial factors, systemic shortcomings, suboptimal medication use and variable awareness of CHD signs and symptoms as barriers to CHD management, whereas family support and culturally appropriate education promoted health care. To optimise CHD secondary prevention for Aboriginal people, health services require adequate resources to achieve best-practice systems of follow up. Routinely engaging clients is required to ensure services meet diverse community needs.

Abstract
PURPOSE Chronic obstructive pulmonary disease (COPD) is characterized by concomitant systemic manifestations and comorbidities such as cardiovascular disease. Little data exist on the prevalence of comorbidities and medication burden in people with COPD attending pulmonary rehabilitation (PR) programs in Australia. This study aimed to determine the prevalence of comorbidities and describe the type and number of medications reported in a sample of patients with COPD referred to PR. METHODS A retrospective audit was conducted on patients referred to PR over a 1-year period. Data were collected on patient demographics, disease severity, comorbidities, and medications by review of patient notes, physician referral, and self-reported medication use. RESULTS Data were available on 70 patients (forced expiratory volume in 1 second = 37.5 [26.0] % predicted). Ninety-six percent of patients had at least 1 comorbidity, and 29% had 5 or more. The most common comorbidities were associated with cardiovascular disease (64% of patients). Almost half of the sample was overweight or obese (49%). Prescription medication use was high, with 57% using between 4 and 7 medications, and 29% using 8 or more. CONCLUSIONS Patients with COPD attending PR in Australia have high rates of comorbidity. The number of medications prescribed for these individuals is similar to that seen in other chronic disease states such as chronic heart failure. Pulmonary rehabilitation presents opportunities for clinicians to educate patients on self-management strategies for multiple comorbidities, review medication usage, and discuss strategies aimed at optimizing adherence with medication regimes.

Abstract
INTRODUCTION Micro-RNA, a new class of small, non-coding RNAs, have been shown to be deregulated in several human carcinomas. In particular, SNP rs2910164 in pre-miR146a appears to be correlated with papillary thyroid carcinoma and may be involved in its genetic predisposition. Since data on follicular thyroid carcinomas (FTC) are lacking, we evaluated the involvement of SNP rs2910164 in FTC. METHODS Thirty-nine cases of FTC and 20 follicular adenomas, defined according to WHO criteria, were selected. DNA and RNA were extracted from formalin-fixed paraffin-embedded blocks of both neoplastic and non-neoplastic areas. The DNA region of pre-miR146a, containing SNP rs2910164, was sequenced. Total RNA including miRNAs was used for stem-loop RT reactions, and applying a standard TaqMan PCR kit protocol for real-time PCR. Wilcoxon signed-rank test and Friedman test were used for statistical analyses. RESULTS In 31% of FTC, the G allele was observed in neoplastic tissues, compared with the non-neoplastic areas (p < 0.05), whereas the CC phenotype was completely absent in tumours. Moreover, the expression of pre-miR146a was found to be significantly down-regulated in neoplastic tissues from FTC cases (p = 0.043), although no significant differences were seen in follicular thyroid adenomas. DISCUSSION The expression profile of pre-miR146a can be correlated with FTC tumourigenesis. The G allele in SNP rs2910164 appears to be correlated with the transition from normal to neoplastic tissue. The GG and GC alleles appear to be associated with an increased risk for FTC, while the CC allele seems to play a protective role.

Abstract
BACKGROUND Shear stress triggers conformational stretching of von Willebrand factor (VWF), which is responsible for its self-association and binding to the platelet receptor glycoprotein (GP)Ibα. This phenomenon supports primary hemostasis under flow. Type 2B VWF natural mutants are considered to have increased affinity for platelet GPIbα. OBJECTIVES To assess the mechanism responsible for the enhanced interaction of the p.R1306W VWF mutant with the platelet receptor. METHODS The interaction of GPIbα with wild-type (WT) and p.R1306W VWF multimers and A1-A2-A3 constructs was investigated with surface plasmon resonance spectroscopy. Analysis of the static VWF conformation in solution was performed with dynamic light scattering spectroscopy. The shear stress-induced self-association of VWF multimers was investigated with atomic force microscopy (AFM) over a 0-60 dyn cm(-2) range. RESULTS WT VWF did not interact with GPIbα under static conditions, whereas the mutant at ~ 2 μg mL(-1) already bound to the receptor. By contrast, the WT and p.R1306W-A1-A2-A3 constructs showed comparable affinities for GPIbα (Kd ~ 20 nm). The hydrodynamic diameter of resting R1306W VWF multimers was significantly greater than that of the wild type (210 ± 60 nm vs. 87 ± 22 nm). At shear forces of < 14 dyn cm(-2) , the p.R1306W multimers rapidly changed conformation, entering a regime of self-aggregation, which, in contrast, was induced for WT VWF by shear forces of > 30 dyn cm(-2) . Mechanical stretching AFM experiments showed that p.R1306W multimers needed less energy per length unit (~ 10 pN) to be stretched than the WT protein. CONCLUSIONS The increased affinity of p.R1306W VWF for GPIbα arises mostly from higher sensitivity to shear stress, which facilitates exposure of GPIbα binding sites.

Abstract
Aspergillus fumigatus has become a leading cause of fungal morbidity and mortality, especially in immunocompromised patients. This fungus is able to grow as a multicellular community and produce a hydrophobic extracellular matrix (ECM), mainly composed of galactomannan and α-1,3 glucans, to protect itself from host defenses and antimicrobial drugs. This matrix envelops the fungus hyphae, binding them into a contiguous sheath on the colony surface, forming a biofilm and increasing the fungal resistance to adverse environmental factors. Adherence to host cells and resistance to physical removal play a key role in fungal colonization and invasion of the host and in a wide range of infections. Here we show that, by using atomic force spectroscopy, it is possible to exploit the peculiar hydrophobicity of the biofilm components (i.e., cell walls, ECM) to detect the biofilm spread, its growth, and lysis on rough surfaces. By means of this approach, we demonstrate that alginate lyase, an enzyme known to reduce negatively charged alginate levels in microbial biofilms, reduces the biofilm adhesion forces suggesting a loss of ECM from the biofilm, which could be used to enhance pharmacological treatments.

Abstract
QUESTION Is aerobic interval training (AIT) more effective than moderate continuous training (MCT) at enhancing aerobic fitness and myocardial remodelling in patients with stable heart failure? DESIGN Randomised controlled trial in which participants were allocated to AIT, MCT, or a control group. SETTING Hospital in Trondheim, Norway. PARTICIPANTS Adults with stable heart failure post myocardial infarction with left ventricular ejection fraction (EF) < 40% on optimal medical management. Exclusion criteria comprised: unstable angina pectoris, uncompensated heart failure, myocardial infarction within four weeks, complex ventricular arrhythmias, no use of Đ-blockers and ACE inhibitors or, any other limitation to exercise. Randomisation of 27 patients allocated nine to each group. INTERVENTIONS The AIT and MCT groups completed two supervised exercise training sessions and one home training session each week for 12 weeks. Those in AIT completed uphill treadmill walking that comprised a warm-up and cool down interspersed with 4 × 4 minute exercise intervals completed at 90-95% of peak heart rate. Intervals were separated by three minutes of walking at 50-70% of peak heart rate (total exercise time = 38 minutes). The MCT participants walked continuously for 47 minutes at 70-75% of peak heart rate. Weekly home training comprised outdoor hill walking. The control group completed 47 minutes of supervised treadmill walking at 70% of peak heart rate once every three weeks. OUTCOME MEASURES The primary outcomes related to exercise capacity (eg, peak rate of oxygen uptake; VO(2peak)); secondary outcomes comprised measures of echocardiography and endothelial function. RESULTS Outcomes were available from 26 participants. The VO(2peak) achieved on completion of training was greater in the AIT group compared with the MCT group (mean difference 4.1; 95% CI 2.4 to 5.8ml/kg/min) and the control group (5.8, 95% CI 3.8 to 7.8ml/kg/min). Compared with the other groups, AIT also conferred greater gains in measures of systolic and diastolic function and endothelial function. CONCLUSION In adults with stable heart failure, AIT conferred greater gains than MCT in improving aerobic capacity and measures reflecting left ventricular and endothelial function.

Abstract
AIM Our goals were to assess the psychometrical characteristics of EHP-30, to test its higher degree of appropriateness compared to the generic Quality of Life-assessment tools for Italian women suffering from endometriosis, and to determine its ability to identify the disease's effects on the patients' psychosocial condition, highlighting critical points that can be modified for future linguistic validation. METHODS Participants to our study were 98 women between 19 and 51-year-old (M=34.4, SD=7.5), selected from patients of the Department of Obstetrics and Gynecology, ARNAS Civico Hospital, Palermo, Italy. All of them had a surgical diagnosis of endometriosis with histological confirmation. Quality of Life was assessed through generic (SF-36) and specific (EHP-30) instruments. RESULTS Our study shows that the current Italian version of EHP-30 is affected by overall weaker construct validity than the English one; it seems that this has to be ascribed to the inadequacy of the EHP-30 translation into Italian. In particular, unsatisfactory reliability levels have been observed for social support and self-image scales. An incorrect order of response categories has been in addition found out for several items of the Italian version of EHP-30. Research results suggest solutions to adopt for a revision of the EHP-30 Italian version that can satisfy the requirements of validity and reliability. CONCLUSION Although requiring a structural and linguistic revision, also the Italian version of a specific measurement instrument as EHP-30 is, appears to be more appropriate than generic tools to assess the quality of life of Italian women suffering for endometriosis.

Abstract
AIM To determine the opinion of health care professionals within Australia, regarding acceptable levels of exertion and symptoms, and referral for exercise rehabilitation in patients with pulmonary arterial hypertension (PAH). METHOD In 2010, 76 health care professionals at a specialist pulmonary hypertension meeting in Australia were surveyed using a self-administered questionnaire. The questionnaire included case studies of patients with PAH in World Health Organization (WHO) functional classes II-IV. For each case study, respondents were asked to report their opinion regarding the acceptable level of exertion and symptoms during daily activities, and whether they would refer the patient for exercise rehabilitation. Three additional questions asked about advice in relation to four specific physical activities. RESULTS The response rate was 70% (n = 53). Overall, 58% of respondents recommended patients undertake daily activities 'as tolerated'. There was no consensus regarding acceptable levels of breathlessness or fatigue, but the majority of respondents considered patients should have no chest pain (73%) and no more than mild light-headedness (92%) during daily activities. Overall, 63% of respondents would have referred patients for exercise rehabilitation. There was little difference in opinion regarding the acceptable level of exertion or symptoms, or referral for exercise rehabilitation, according to functional class. However, the patients' functional class did influence the advice given regarding the specific physical activities. CONCLUSION In 2010, there were inconsistencies between individual health care professionals within Australia regarding appropriate levels of physical exertion and acceptable symptoms during daily activities. Almost two-thirds of the respondents reported they would refer patients for exercise rehabilitation.
