Abstract
BACKGROUND Low-cost meshes (LCM) have been successfully used in low-income countries (LIC) over the past decades, demonstrating comparable surgical outcomes to commercial meshes at a fraction of the cost. However, LIC sterilisation standards (autoclave sterilisation at 121 °C) do not meet UK regulations for medical devices, which require either ethylene oxide (EO) sterilisation or steam sterilisation at 134 °C. Therefore, the aim of this study was to sterilise UK LCM and characterise their mechanical properties and in vitro biocompatibility to verify whether EO sterilisation causes changes in the mechanical properties and biocompatibility of LCM. METHODS EO sterilised LCM were used. Uniaxial tensile tests were performed to measure mechanical properties. Biocompatibility was measured through viability and morphology of Human Dermal Fibroblasts (HDFs) cultured in mesh-conditioned media, and by calculating the metabolic activity and proliferation of HDFs attached on the meshes, with alamarBlue assay. RESULTS Break stress of LCM1 was significantly higher than LCM2 (p < 0.0001), while Young's modulus of LCM1 was significantly lower than LCM2 (p < 0.05) and there was no significant difference in break strain. Viability and morphology showed no significant difference between LCM and control. Attachment and proliferation of HDFs on LCM showed a better proliferation on LCM2 than LCM1, with values similar to the control at the final time point. CONCLUSIONS We demonstrated that EO sterilisation affects LCM mechanical properties, but they still have values closer to the native tissues than the commercially available ones. We also showed that in vitro biocompatibility of LCM2 is not affected by EO sterilisation, as HDFs attached and proliferated on the mesh, while EO affected attachment on LCM1. A more detailed cost analysis of the potential savings for healthcare systems around the world needs to be performed to strengthen the cost-effectiveness of this frugal innovation.

Abstract
The vast majority of pelvic and intra-abdominal surgery is undertaken through at least one incision, through either the linea alba or the rectus sheath. These connective tissue layers are formed from the aponeuroses of the rectus muscles (anterior and posterior rectus sheath) and are vital for the structural integrity of the abdominal wall. Poor healing of these connective tissues after surgery can lead to significant morbidity for patients, who can develop unsightly and painful incisional hernias. Fibroblasts within the rectus sheath are responsible for laying down and remodeling collagen during the healing process after surgery. Despite their importance for this healing process, such cells have not been studied in vitro. In order to carry out such work, researchers must first be able to isolate these cells from human tissue and culture them successfully so they may be used for experimentation. This article provides an extensive and detailed protocol for the isolation, culture, cryopreservation, and thawing of human rectus sheath fibroblasts (RSFs). In our hands, this protocol develops confluent cultures of primary fibroblasts within 2 weeks, and sufficient cultures ready for freezing and storage after a further 2 to 4 weeks. © 2023 The Authors.

Abstract
Abstract
Study question
The study aims to assess the commonalities and interdependence of couples undergoing first-level Assisted Reproductive Techniques (ART) as regards body-image avoidance referred to body-image dissatisfaction.
Summary answer
Partners’ functioning seem specular yet not interdependent, as not showing a couple-as-a-unit modality of functioning. Body-image avoidance is only influenced by intra-personal variables. What is known already: Stressful bodily emotions and body perception related to infertility and ART are critical aspects for people desiring having children. Infertility undermines women’s self-esteem and body-image, damaging their self-identity as women, while in males infertility associates with body dissatisfaction referring to perceived reduced physical fitness and personal failure, thus undermining their body virility. For infertile women, body-image dissatisfaction associates with reduced marital adjustment, and vice-versa; yet no study has considered how males body-image dissatisfaction associates with marital satisfaction. Nonetheless, couples should be considered as a unit, considering that infertile couples’ adjustment is influenced by their own, and their partners’, perceived stress.
Study design, size, duration
The study follows a cross-sectional design and is part of an ongoing transversal and longitudinal project, started in 2012, investigating the well-being of couples undergoing ART. For the present study only a minority of the existing data were considered, thus only including couples at the first level of ART with the intent of investigating couples’ commonalities and interdependence before treatments pervasiveness increases.
Participants/materials, setting, methods
Minimum N = 79 couples needed to be considered according to Power analysis results. N = 118 couples aged 24 to 46 years (women Mage=34.92, SD = 3.98; men Mage=37.45, SD = 5.25) were included, and declaring trying to get pregnant from 1 to 8 years (M = 3.18; SD = 1.99) and to never had children, although 22.9% of women had at least an abortion. Participants completed the Body-Image Avoidance Questionnaire, Toronto Alexithymia Scale–20, Dyadic Adjustment Scale, Symptom Checklist–90-Revised and Experiences in Close Relationships Scale-Revised.
Main results and the role of chance
The sample presents non-clinical levels of functioning referring to their psychological symptoms, alexithymia and body-image avoidance. Multivariate rank tests show that females report significantly higher levels of body-image avoidance (stat=–5.73; adj.p=.001), psychological symptoms (stat=–4.58; adj.p=.001) and romantic anxious attachment (stat=–3.33; adj.p=.005). These differences were confirmed also after applying multiplicity control. Moreover, bi-variate Pearson’s r correlations show an association among partners’ dyadic adjustment (r=.293; p<.001), albeit their overall level of dyadic adjustment is low. Significant correlations among partners also emerged as regards psychological symptoms (r=.258; p<.001) and alexithymia (r=.16; p=.05). The couple-effect, thus considering the couple as the unit of analysis, was modeled through an Actor-Partner Interdependence Model. For both partners, dyadic adjustment’s actor-effect associates with body-image avoidance (women: β = 0.133, p=.026; man: β = 0.133, p=.026). Furthermore, for both men and women, psychological symptoms’ actor-effect associate to body-image avoidance (women: β = 0.467, p<.00; men: β = 0.499, p=.001). Comparing the level of influence of actor and partner effects among partners, the psychological symptoms’ actor effect results significantly more influential than the partner-effect (women: Δ = 0.378, p=.015; men: Δ = 0.587, p=.001). Only for males, alexithymia’s actor effect is significant (β = 0.499; p=.001).
Limitations, reasons for caution
Results should be considered in light of some limitations. Specifically, the cross-sectional study design, lack of a control group with no infertility issues, the use of self-report measures, homogeneity among couples and the sample small sample size (although sample size was appropriate to retain a power of at least .8).
Wider implications of the findings: Results support the differentiation of gender-specific psychosocial interventions along the ART path, preventing and mitigating the negative impact of infertility and ART on body-image dissatisfaction and avoidance and on the couples’ well-being.

Abstract
Palladium diselenide ([Formula: see text]) is a recently isolated layered material that has attracted a lot of interest for its pentagonal structure, air stability and electrical properties that are largely tunable by the number of layers. In this work, multilayer [Formula: see text] is used as the channel of back-gate field-effect transistors, which are studied under repeated electron irradiations. Source-drain [Formula: see text] electrodes enable contacts with resistance below [Formula: see text]. The transistors exhibit a prevailing n-type conduction in high vacuum, which reversibly turns into ambipolar electric transport at atmospheric pressure. Irradiation by [Formula: see text] electrons suppresses the channel conductance and promptly transforms the device from n-type to p-type. An electron fluence as low as [Formula: see text] dramatically changes the transistor behavior, demonstrating a high sensitivity of [Formula: see text] to electron irradiation. The sensitivity is lost after a few exposures, with a saturation condition being reached for fluence higher than [Formula: see text]. The damage induced by high electron fluence is irreversible as the device persists in the radiation-modified state for several hours, if kept in vacuum and at room temperature. With the support of numerical simulation, we explain such a behavior by electron-induced Se atom vacancy formation and charge trapping in slow trap states at the [Formula: see text] interface.

Abstract
OBJECTIVE Poor clinical outcomes following peripheral nerve injury (PNI) are partly attributable to the limited rate of neuronal regeneration. Despite numerous potential drug candidates demonstrating positive effects on nerve regeneration rate in preclinical models, no drugs are routinely used to improve restoration of function in clinical practice. A key challenge associated with clinical adoption of drug treatments in nerve injured patients is the requirement for sustained administration of doses associated with undesirable systemic sideeffects. Local controlled-release drug delivery systems could potentially address this challenge, particularly through the use of biomaterials that can be implanted at the repair site during the microsurgical repair procedure. APPROACH In order to test this concept, this study used various biomaterials to deliver ibuprofen sodium or sulindac sulfide locally in a controlled manner in a rat sciatic nerve injury model. Following characterisation of release parameters in vitro, ethylene vinyl acetate tubes or polylactic-co-glycolic acid wraps, loaded with ibuprofen sodium or sulindac sulfide, were placed around directly-repaired nerve transection or nerve crush injuries in rats. MAIN RESULTS Ibuprofen sodium, but not sulindac sulfide caused an increase in neurites in distal nerve segments and improvements in functional recovery in comparison to controls with no drug treatment. SIGNIFICANCE This study showed for the first time that local delivery of ibuprofen sodium using biomaterials improves neurite growth and functional recovery following PNI and provides the basis for future development of drug-loaded biomaterials suitable for clinical translation.

Abstract
INTRODUCTION Primary hyperparathyroidism is associated with a cluster of cardiovascular manifestations, including hypertension, leading to increased cardiovascular risk. PURPOSE The aim of our study was to investigate the ambulatory blood pressure monitoring-derived short-term blood pressure variability in patients with primary hyperparathyroidism, in comparison with patients with essential hypertension and normotensive controls. METHODS Twenty-five patients with primary hyperparathyroidism (7 normotensive,18 hypertensive) underwent ambulatory blood pressure monitoring at diagnosis, and fifteen out of them were re-evaluated after parathyroidectomy. Short-term-blood pressure variability was derived from ambulatory blood pressure monitoring and calculated as the following: 1) Standard Deviation of 24-h, day-time and night-time-BP; 2) the average of day-time and night-time-Standard Deviation, weighted for the duration of the day and night periods (24-h "weighted" Standard Deviation of BP); 3) average real variability, i.e., the average of the absolute differences between all consecutive BP measurements. RESULTS Baseline data of normotensive and essential hypertension patients were matched for age, sex, BMI and 24-h ambulatory blood pressure monitoring values with normotensive and hypertensive-primary hyperparathyroidism patients, respectively. Normotensive-primary hyperparathyroidism patients showed a 24-h weighted Standard Deviation (P < 0.01) and average real variability (P < 0.05) of systolic blood pressure higher than that of 12 normotensive controls. 24-h average real variability of systolic BP, as well as serum calcium and parathyroid hormone levels, were reduced in operated patients (P < 0.001). A positive correlation of serum calcium and parathyroid hormone with 24-h-average real variability of systolic BP was observed in the entire primary hyperparathyroidism patients group (P = 0.04, P = 0.02; respectively). CONCLUSION Systolic blood pressure variability is increased in normotensive patients with primary hyperparathyroidism and is reduced by parathyroidectomy, and may potentially represent an additional cardiovascular risk factor in this disease.

Abstract
We prove theoretically that when a soft solid is subjected to an extreme deformation, wrinkles can form on its surface at an angle that is oblique to a principal direction of stretch. These oblique wrinkles occur for a strain that is smaller than the one required to obtain wrinkles normal to the direction of greatest compression. We go on to explain why they will probably never be observed in real-world experiments.This article is part of the themed issue 'Patterning through instabilities in complex media: theory and applications.'

Abstract
AIM This study aims to investigate the influence of the "romantic attachment" style, stressful life events, social factors on the risk of developing a depression during pregnancy and on the severity of depressive symptoms. METHODS The study started with a screening on a sample of 453 women, during their third trimester of pregnancy, to which has been administered a survey data form, the Edinburgh Postnatal Depression Scale (EPDS) and the Experience in Close Relationship (ECR). Based on the results at EPDS, a clinical group of pre-natal depression (D=89) was selected and compared with a control group (C=89), in regards to psychopathological and social variables, exposure to stressful life events and attachment patterns. Analysis of correlation were performed to evaluate the influence of these factors on depressive symptoms severity. RESULTS In D group, 52.8% of subjects reported previous psychiatric disorders and 49.4% a familiarity; 29.2% of these women complains of conflicts with their family of origin and 32.6% with partner. The ECR showed a prevalence of "fearful-avoidant" attachment style in clinical group (29.2% vs 1.1%, p=0.000); besides, ECR dimensions ("Avoidance", "Anxiety"), correlate with the severity of depressive symptoms. CONCLUSIONS Positive family history for psychiatric disorders and an insecure romantic attachment might influence the development and the severity of perinatal depression.

Abstract
BACKGROUND To assess personality characteristics of women who develop perinatal depression. METHODS The study started with a screening of a sample of 453 women in their third trimester of pregnancy, to which was administered a survey data form, the Edinburgh Postnatal Depression Scale (EPDS) and the Minnesota Multiphasic Personality Inventory 2 (MMPI-2). A clinical group of subjects with perinatal depression (PND, 55 subjects) was selected; clinical and validity scales of MMPI-2 were used as predictors in hierarchical cluster analysis carried out. RESULTS The analysis identified three clusters of personality profile: two "clinical" clusters (1 and 3) and an "apparently common" one (cluster 2). The first cluster (39.5%) collects structures of personality with prevalent obsessive or dependent functioning tending to develop a "psychasthenic" depression; the third cluster (13.95%) includes women with prevalent borderline functioning tending to develop "dysphoric" depression; the second cluster (46.5%) shows a normal profile with a "defensive" attitude, probably due to the presence of defense mechanisms or to the fear of stigma. CONCLUSION Characteristics of personality have a key role in clinical manifestations of perinatal depression; it is important to detect them to identify mothers at risk and to plan targeted therapeutic interventions.

Abstract
The mechanical properties of cell nuclei have been demonstrated to play a fundamental role in cell movement across extracellular networks and micro-channels. In this work, we focus on a mathematical description of a cell entering a cylindrical channel composed of extracellular matrix. An energetic approach is derived in order to obtain a necessary condition for which cells enter cylindrical structures. The nucleus of the cell is treated either (i) as an elastic membrane surrounding a liquid droplet or (ii) as an incompressible elastic material with Neo-Hookean constitutive equation. The results obtained highlight the importance of the interplay between mechanical deformability of the nucleus and the capability of the cell to establish adhesive bonds and generate active forces in the cytoskeleton due to myosin action.

Abstract
BACKGROUND AND AIM Non-alcoholic fatty liver disease (NAFLD) has been found to be strongly related to an increased arterial stiffness in patients with essential hypertension, suggesting a pathophysiologic link between major cardiovascular and metabolic abnormalities associated with liver steatosis and the functional and structural alterations of the arterial wall. The aim of our study was to investigate, in a group of essential hypertensive patients without additional cardiovascular risk factors, the relationship between NAFLD and arterial stiffness. METHODS AND RESULTS Sixty-eight consecutive patients with essential hypertension underwent 24-h ambulatory blood pressure monitoring (ABPM) and were separated according to the presence (n = 40) or absence (n = 28) of NAFLD at liver ultrasonography. The Ambulatory Arterial Stiffness Index (AASI) and Symmetric AASI (Sym-AASI) were derived from ABPM tracings. Patients with diabetes, obesity, hyperlipidaemia or other risk factors for cardiovascular or liver disease were excluded. Hypertensive patients were compared with a normotensive control group.The two hypertensive groups had comparable age, sex distribution and clinic/ABPM blood pressure levels. In hypertensive patients with NAFLD, body mass index, fasting glucose, insulin, homeostasis model of assessment of insulin resistance index and triglyceride levels were higher, whereas plasma adiponectin was lower than in patients without NAFLD. In hypertensive patients, AASI and Sym-AASI were higher (P < 0.001) than in normotensive subjects, but both indices of vascular stiffness were comparable in patients with and without NAFLD. CONCLUSIONS In essential hypertensive patients without additional cardiovascular risk factors, NAFLD is associated with insulin resistance but not with increased arterial stiffness.

Abstract
The reform of mandatory employment in Italy, performed by the national Law 68/99, represented a crucial step for the assertion of the right to work for disabled people. The aim of our experience is to obtain information about health and safety conditions of disabled people employed in targeted workplaces and about the issues for that workers keep or lose their job, possibly in order to take actions on workplaces and to improve job conditions for all other workers also. In this paper we used data regarding targeted employments of disabled people, collected during the year 2008 in the Province of Florence.

Abstract
There is an up-surge of interest in antioxidants because of their potential use in mitigating a wide array of oxidative stress mediated diseases. In the course of our literature search for diverse functional groups, with utility in the design of potential drugs for preventing oxidative stress related cell injury, we have collected a small literature library of core structures or moieties possessing antioxidant activities. These functional groups can be re-configured into robust antioxidants drug molecules, in their own right, or incorporated into drug structures where the antioxidant capability is required. The lack of single papers presenting a collection of diverse small molecule antioxidant moieties as potential design leads prompted us to write this short review of twenty five such functionalities.

Abstract
Endoscopic submucosal dissection is a difficult procedure with frequent complications. Our aim was to test the feasibility of utilizing a second endoscopic arm to improve the dissection. An Olympus prototype blind probe, with an external diameter of 6 mm and a 2.8-mm working channel, was used as a second endoscopic arm. Its purpose was to lift the lesion during dissection. The main endoscope served both to perform the dissection and to visualize the second endoscopic arm in the monitor. Eight patients with polypoid lesions in the rectum or distal sigmoid were treated successfully. The procedure was feasible, and submucosal exposure was ameliorated allowing easier dissection. The resection was curative in all cases. No recurrences have been detected during up to 18-months of follow-up. A small perforation and two cases of delayed bleeding were managed nonsurgically. Applying counter-traction with a second endoscopic arm can facilitate submucosal dissection of distal colorectal lesions.

Abstract
OBJECTIVE The percentage measurement of hypochromic red cells (HYPO) and reticulocyte haemoglobin content (CHr) using the ADVIA system has recently been validated as a useful tool in indicating iron deficiency, also in cases of chronic diseases such as renal failure. The aim of this study was to evaluate the extent to which the red cell parameters, RBC-Y and RET-Y, provided by Sysmex XE 2100, correlate with HYPO and CHr. MATERIAL AND METHODS The laboratory markers of iron status were evaluated together with HYPO, CHr, RBC-Y and RET-Y in 92 healthy subjects (C), 42 iron-deficient patients (ID) and 88 uraemic patients receiving regular dialysis treatment (RDT). RESULTS In ID patients, increased HYPO and decreased RBC-Y, CHr and RET-Y values, with no overlapping with reference values, were found and a significant correlation was present between ADVIA 120 and Sysmex indices (p<0.001 for each correlation). In RDT patients, HYPO median values were increased with a wide distribution of values (95 % reference range = 0.7-27.5 % and 0.7-22.6 % in men and women, respectively). In contrast, RBC-Y was normal/increased (95 % reference range = 169.4-191.1 and 168.7-190.5 in men and women, respectively), even though there was a significant correlation between them (p<0.001). CHr and RET-Y values were within the reference range; moreover, in these patients mean cell volume of red cells and of reticulocytes (MCV and MCVr) median values were increased. CONCLUSIONS This study confirmed the validity of RBC-Y in the management of ID, but not in RDT, where the diagnostic power of RBC-Y as an index of cell hypochromia is limited owing to high MCV values.

Abstract
BACKGROUND AND STUDY AIMS Biliary stents have been found to interfere with endoscopic ultrasound (EUS) tumor (T) and nodal (N) staging in patients with periampullary cancer. Our aim was to determine whether this also occurs in patients with pancreatic head cancer. PATIENTS AND METHODS We studied a consecutive series of patients who were undergoing preoperative EUS for diagnosis and staging of suspected pancreatic cancer, some of whom had biliary stents in situ and some of whom did not. The main end point was the uni- and multivariate association of biliary stenting with T and N mis-staging by EUS. The surgical T and N stages were used as gold standards. RESULTS A total of 65 patients were identified (19 with biliary stents in situ and 46 without). Surgical stage T4 was found more frequently in patients with stents (53% vs. 22%, P = 0.014). The T stage by EUS was correct in 85% of the patients without biliary stents and in 47% of the patients with stents. The frequency of mis-staging by EUS was significant only among patients with a biliary stent. The distribution by EUS N stage did not differ significantly from the surgical N-stage distribution in the two groups of patients. According to the multivariate analysis, patients with stents were 6.55 times more likely to be incorrectly T staged (95% confidence interval [CI] 1.69-25.49) and 3.71 times more likely to be incorrectly N staged (95% CI 1.11-12.45) than patients without stents. CONCLUSIONS The results add support to the recommendation that EUS staging of pancreatic head neoplasms should be performed prior to stent placement.

Abstract
It is well known that change in apoptosis may modulate the natural story of illness, and that many drugs may act through modulation of apoptosis, but the role of steroids in acting through apoptosis in different settings, including renal diseases, has still to be elucidated. We studied the in vivo effects of steroids by oral assumption (10 to 25 mg/deltacortene) or by intravenous pulses (300 to 1000 mg/dose) on apoptosis and cellular subsets of peripheral lymphocytes, by evaluating DNA-fragmentation and lymphocyte subsets in 79 subjects: 22 controls and 57 patients with various renal diseases (25 Lupus-GN, 19 membranous-GN (MGN), 6 rapidly progressive-GN (RPGN), 2 acute interstitial nephritis (AIN), 5 on chronic dialysis. Baseline apoptosis was present in 1/22 (4.5%) of controls, 3/25 (12%) SLE, 2/6 (33.3%) RPGN and 10/19 (52.6%) MGN. A significant decrease in CD3+CD8+ cell count and a significant increase of the CD3+CD4/CD3+CD8+ ratio were found in apoptosis-positive subjects. DNA fragmentation did not change after oral steroids, paralleling a 22 to 32% decrease in total lymphocytes. Following intravenous methylprednisolone pulses, a deeper drop of all lymphocyte subsets was observed, while DNA fragmentation turned from present to absent in 2 MGN, but not in 2 RPGN, and from absent to present in 1 ARF and 1 SLE, independently of the dosage. We demonstrated that the presence of apoptosis in renal diseases is associated with decreased CD3+CD8+ cell count. Furthermore, steroid intravenous pulses, besides inducing a profound decrease in lymphocyte subsets, do exert a dual effect on baseline leukocyte apoptosis, eventually leading to a reversal of baseline patterns, either turning from negative to positive or from positive to negative. Oral steroid therapy did not influence baseline apoptosis.

Abstract
The integrity of articular cartilage depends on the proper functioning and mechanical stimulation of chondrocytes, the cells that synthesize extracellular matrix and maintain tissue health. The biosynthetic activity of chondrocytes is influenced by genetic factors, environmental influences, extracellular matrix composition, and mechanical factors. The mechanical environment of chondrocytes is believed to be an important determinant for joint health, and chondrocyte deformation in response to mechanical loading is speculated to be an important regulator of metabolic activity. In previous studies of chondrocyte deformation, articular cartilage was described as a biphasic material consisting of a homogeneous, isotropic, linearly elastic solid phase, and an inviscid fluid phase. However, articular cartilage is known to be anisotropic and inhomogeneous across its depth. Therefore, isotropic and homogeneous models cannot make appropriate predictions for tissue and cell stresses and strains. Here, we modelled articular cartilage as a transversely isotropic, inhomogeneous (TI) material in which the anisotropy and inhomogeneity arose naturally from the microstructure of the depth-dependent collagen fibril orientation and volumetric fraction, as well as the chondrocyte shape and volumetric fraction. The purpose of this study was to analyse the deformation behaviour of chondrocytes using the TI model of articular cartilage. In order to evaluate our model against experimental results, we simulated indentation and unconfined compression tests for nominal compressions of 15%. Chondrocyte deformations were analysed as a function of location within the tissue. The TI model predicted a non-uniform behaviour across tissue depth: in indentation testing, cell height decreased by 43% in the superficial zone and between 11 and 29% in the deep zone. In unconfined compression testing, cell height decreased by 32% in the superficial zone, 25% in the middle, and 18% in the deep zones. This predicted non-uniformity is in agreement with experimental studies. The novelty of this study is the use of a cartilage material model accounting for the intrinsic inhomogeneity and anisotropy of cartilage caused by its microstructure.

Abstract
Patients with inflammatory bowel disease (IBD) have an increased risk of thrombotic complications. Arterial and venous system may be involved. Moreover, mesenteric microvascular thrombosis has been hypothesised as a contributing factor in the pathogenesis of IBD. Early atherosclerosis is a clinical feature common to several inflammatory and immunological diseases in which atherothrombotic complication represents one of the most important cause of mortality and morbidity. We investigate the prevalence and the entity of the early stages of vascular disease in a population of IBD patients without the classical cardiovascular risk factors, by measuring the intima-media thickness (IMT) of the common carotid artery. We found that IBD patients have an increased risk of early atherosclerosis than healthy controls as showed by greater values of carotid IMT and that homocysteine levels and age were independently associated with the increased arterial wall thickness.

Abstract
BACKGROUND Patients with inflammatory bowel disease have an increased risk of thrombotic complications; moreover, mesenteric microvascular thrombosis has been hypothesized as a contributing factor in the pathogenesis of inflammatory bowel disease. AIM To assess the extent of subclinical atherosclerosis in inflammatory bowel disease by measuring the intima-media thickness of the common carotid artery. METHODS Fifty-two patients were enrolled in the study. Patients aged >45 years, with a history of cardiovascular disease and known risk factors for atherosclerosis were excluded from the study. Twenty healthy subjects were studied as controls. Carotid ultrasonography was performed in all patients and controls. intima-media thickness was measured proximal to the carotid bifurcation over both right and left common carotid arteries. The clinical characteristics and the laboratory parameters relevant to disease activity were recorded for all inflammatory bowel disease patients. In particular, plasma homocysteine, a well-known risk factor for thrombosis, was assessed. RESULTS Common carotid artery intima-media thickness was significantly higher in inflammatory bowel disease patients (0.63 +/- 0.15 mm) compared with controls (0.53 +/- 0.08 mm). Multiple regression analysis revealed a significant association of carotid intima-media thickness with homocysteine levels and age. CONCLUSIONS Inflammatory bowel disease patients have an increased risk of early atherosclerosis than healthy controls as showed by greater values of carotid intima-media thickness. Homocysteine levels and age resulted independently associated with the increased arterial wall thickness.

Abstract
BACKGROUND AND AIMS Probiotics have been used for cure and prevention of several clinical conditions. However, further insights into the mechanism of action are needed to understand the rationale of their use. The aim of this study was to investigate the influence of Lactobacillus GG on the genetic expression patterns in the small bowel mucosa. METHODS Six male patients (38+/-5 years) with endoscopically proven oesophagitis were enrolled. All patients were treated for 1 month with esomeprazole and randomised to receive Lactobacillus GG or placebo. After 1 month of treatment, upper endoscopy was repeated. Biopsies of the duodenal mucosa were taken prior to and after the treatment, and the genes expression patterns were assessed using GeneChip Human U133A array. Genes with significant expression changes were selected and analysed to identify specific cellular pathways modified by Lactobacillus GG. To support the array data, 10 target genes were studied using Syber-Green PCR. RESULTS Microarray analysis showed that Lactobacillus GG administration determined the up- and down-regulation of 334 and 92 genes, respectively. Real-time PCR confirmed the reliability of the analysis. Lactobacillus GG mainly affected the expression of genes involved in immune response and inflammation (TGF-beta and TNF family members, cytokines, nitric oxide synthase 1, defensin alpha 1), apoptosis, cell growth and cell differentiation (cyclins and caspases, oncogenes), cell-cell signalling (ICAMs and integrins), cell adhesion (cadherins), signal transcription and transduction. CONCLUSIONS These data indicate that administration of Lactobacillus GG is associated with a complex genetic response of the duodenal mucosa, reflected by the up- and down-regulation of several genes involved in specific cellular pathways.

Abstract
Fetal nucleated red blood cells (FNRBCs) circulate in the maternal blood throughout pregnancy. Even if the frequency of fetal cells in the maternal circulation remains to be ascertained, complications of pregnancy such as fetal cells aneuploidies, preeclampsia, abnormal Doppler of the uterine artery without symptoms of preeclampsia, fetal growth restriction and polyhydramnios are associated with an increased feto-maternal trafficking. Based on these observations, previous studies have suggested that determination of the fetal nucleated red blood cell count (FNRBCC) might be a useful non-invasive screening test, either alone or in combination with existing maternal tests, for the non-invasive assessment of aneuploidies, in particular Down syndrome (DS). In this paper we have evaluated the distribution of FNRBCC in a set of 18 normal pregnancies and 18 pregnancies with a trisomy 21-affected fetus, matching for gestational age, maternal age, and, when possible, fetal gender, in order to quantify the difference in the number of fetal cells between the two populations. Maternal blood was collected from each pregnant woman two to three weeks after amniocentesis after knowing the cytogenetic results. Correlation of FNRBCC with the gestational week and clinical status (affected vs. non affected) by multiple regression analysis provided significant results (p < 0.001). Adjusted values of FNRBCC were 48 +/- 10.2 in controls and 301 +/- 17.01 in DS cases, corresponding to a 6.27 fold increase. These retrospective results prompt a prospective evaluation of the use of FNRBCC for screening purposes.

Abstract
Up to 70% of patients with typical symptoms of gastroesophageal reflux disease (GERD) have neither definite endoscopic oesophageal breaks nor Barrett's oesophagus at upper endoscopy. These patients suffer from non-erosive reflux disease (NERD), also termed endoscopy-negative reflux disease or symptomatic GERD. NERD patients appear as a heterogeneous population with multiple and substantially different mechanisms implicated in the genesis of symptoms. In fact, patients with NERD may be divided into 3 groups on the basis of 24-hour pH monitoring: 1) patients with an abnormal acid exposure time (AET); 2) patients who demonstrate a normal AET, but in whom symptoms and reflux events are significantly correlated (hypersensitive oesophagus) and 3) patients with typical reflux symptoms but in whom all parameters of the pH study are normal. There is no gold standard for the diagnosis of NERD but a well-taken history can be, usually, sufficient to confirm the diagnosis and begin therapy. Thus, the more sensitive tool for the diagnosis of NERD is proton pump-inhibitor (PPI) test. The aims of NERD treatment are: symptoms relieve, restore quality of life and maintain clinical remission. Proton pump-inhibitors (PPIs) in full doses represent the treatment of choice of NERD patients, even if overall, clinical trials showed a lower efficacy in symptoms control when compared to patients with erosive oesophagitis. Patients with NERD often need long-term therapy for symptoms control. ''On demand'' PPI therapy has been considered as the most cost-effective strategy for the long-term treatment of NERD. In conclusion, many data indicate that NERD is a disorder in its own right that shares symptoms with other GERD groups. However further studies are needed to better define the natural history and improve the treatment of this disorder.

Abstract
BACKGROUNDS AND OBJECTIVE Aim of the present study was to evaluate the clinical correlates of small bowel CT patterns in patients with Crohn's disease (CD), as compared to barium studies and endoscopic findings, as far as parameters of disease activity are concerned. MATERIAL AND METHODS Thirty five patients with pathologically proven CD were studied by means of helical single detector CT (13) or multidetector CT (22), after administration of low density contrast by mouth (13) or by nasojeunal tube (22). Eight hours later, all patients were studied with barium administered by mouth (13) or with barium and methilcellulose administered by nasojeunal tube (22). Clinical activity was assessed by CDAI score, ESR, CRP, alpha1 glycoprotein and fibrinogen levels. In twenty one patients, colonoscopy was also performed. RESULTS Sensitivity of small bowel CT versus endoscopy was of 88% while sensitivity of barium studies was of 77% versus endoscopic findings, and it reached 100% for the combination of both exams. We found positive correlations between the detection at CT of "target sign" and a CDAI score > 150 or abnormal values of CRP, ESR, alpha1 glycoprotein. Abnormal ESR or fibrinogen levels were correlated with the detection of fistulas at CT scans. The diameter of enlarged mesenteric lymph nodes was correlated with alpha1 glycoprotein values. No similar correlations were detected for contrast radiology findings. DISCUSSION This study underscores the clinical usefulness of performing small bowel CT in adjunct to conventional diagnostic studies in Crohn's disease patients. CT findings (either by oral route or nasojeunal tube) correlate with parameters of disease activity.

Abstract
Intercellular adhesion molecule (ICAM)-1 is a single-chain cell surface glycoprotein that plays an important role in the recruitment of leukocytes at sites of inflammation and is up-regulated in intestinal mucosa of inflammatory bowel disease (IBD). ICAM-1 gene lies on chromosome 19p13, implicated in determining susceptibility to IBD. The human ICAM-1 gene contains two polymorphic sites in codon 241 (G241R) and 469 (K469E) which have been implicated in the susceptibility to a range of degenerative and inflammatory diseases. Recently, several reports have shown discordant data regarding the association of these polymorphisms with IBD. In particular, we found an association of IBD with the E/E genotype while allele E469 was associated with a subgroup of patients with more extensive location of Crohn's disease and penetrating behaviour. However, other studies reached different conclusions. A possible explanation for the discrepancy of results is probably the influence of the different geographic distribution of the genetic mutations.

Abstract
BACKGROUND Intercellular adhesion molecule 1 plays an important role in the recruitment of leucocytes at sites of inflammation and is up-regulated in intestinal mucosa of inflammatory bowel disease. Intercellular adhesion molecule 1 gene lies on chromosome 19p13, implicated in determining susceptibility to inflammatory bowel disease. Recently, the polymorphism K469E of intercellular adhesion molecule 1 gene has been identified. AIM To assess the potential association of this polymorphism with inflammatory bowel disease. PATIENTS A total of 165 inflammatory bowel disease patients, 75 with Crohn's disease and 90 with ulcerative colitis, and 187 controls were studied. METHODS The K469E polymorphism was detected by polymerase chain reaction and restriction enzyme analysis. Statistical analysis was performed by chi2-test. RESULTS In inflammatory bowel disease, the distribution of intercellular adhesion molecule 1 genotypes was 24.9% E/E, 44.2% E/K and 30.9% K/K. In controls, 11.8% showed E/E genotype, 55.6% E/K and 32.6% K/K. The frequency of the E/E genotype was significantly higher in inflammatory bowel disease (Crohn's disease and ulcerative colitis) patients than in controls. Subgroup analysis showed that the frequency of the E469 allele was significantly increased only in Crohn's disease patients with ileocolonic location of disease and penetrating behaviour compared with controls. CONCLUSIONS We found an association of inflammatory bowel disease with the E/E genotype of intercellular adhesion molecule 1 gene, while allele E469 was associated with a subgroup of Crohn's disease patients with more extensive location of disease and penetrating behaviour. However, further studies are needed to confirm our findings.

Abstract
The isolation and analysis of nucleated fetal cells (NFCs) from maternal blood may represent a new approach to noninvasive prenatal diagnosis. Although promising, these techniques require highly accurate separation of NFCs from nucleated cells of maternal origin; the two major problems limiting these techniques are the relative rarity of fetal cells in maternal blood and the need to establish their fetal origin. We now report a novel procedure that has allowed accurate separation of NFCs from maternal cells. The technique reported involves direct micromanipulator isolation of histochemically identified hemoglobin F-positive nucleated cells to obtain fetal nucleated red blood cells (FNRBCs) of high yield and purity. Using this technique, followed by cell-by-cell multicolor fluorescence in situ hybridization (FISH) analysis of purified FNRBCs, we were able to detect some of the most common human aneuploidies (including Down syndrome, Klinefelter syndrome, and trisomy 13) in 33 pregnant women referred for amniocentesis. The procedure used, which can be completed in <72 hrs, produced complete concordance with the results of amniocentesis. We also confirm findings of prior studies suggesting that the number of FNRBCs in maternal circulation is remarkably higher in abnormal pregnancies than in normal pregnancies, especially in women carrying a fetus with trisomy 21.

Abstract
Currently, prenatal detection of Down syndrome and other most common aneuploidies relies on invasive procedures such as amniocentesis and villocentesis, and on non-invasive screening tests such as second trimester maternal serum screening (Triple test), and first trimester screening (ULTRA-screen). However, it well known that invasive techniques carry a small risk of fetal loss, while both Triple test and ULTRA-screen are not diagnostic, may miss from 15 - 40 % of cases of Down syndrome, in addition to having a 5 - 8 % rate of false-positives. We now report clear evidence that the number of fetal nucleated red blood cells (FNRBCs) in the maternal circulation is remarkably higher in pregnant women carrying aneuploid fetuses, especially in cases of Down syndrome. These results are in agreement with the findings of other investigators using different methods, and suggest that the number of FNRBCs present in the maternal blood sample could be used as additional marker, in concert with existing screening tests, to improve non-invasive detection of Down syndrome, and other most common aneuploidies.

Abstract
BACKGROUND To verify the availability of foods containing phytoestrogens, the quality of available products, the degree of knowledge of these foods by dealers, the willingness of dealers to give cooperation in preparation of the MENFIS study, a study assessing the efficacy of a phytoestrogen rich diet on the long term effects of menopause. METHODS Perspective research by questionnaires carried out in the herbalist's shops of Bari. RESULTS For the aims of the study the herbalist's shops resulted in being the most suitable, because they were the most supplied with these products and with natural foods, with a high degree of knowledge of these foods and a helpfulness towards the users, perhaps because of the strong motivation towards this type of diet. CONCLUSIONS The easy availability of these products, the good preparation of managers of the herbalist's shops and their good experience is a sound basis for those intending to start dietary programs with phytoestrogen rich foods.

Abstract
BACKGROUND To value the level of acceptance of the Memphis Study, (a random clinical study suggested verifying the efficacy of a diet enriched with phytoestrogens to prevent menopausal problems), and underlining the reasons which induce the acceptance or refusal of the study. STUDY DESIGN Prospective study. METHODS Meeting groups have been held with 82 women needing Day Hospital treatment for Menopause at III Department of Obstetrics and Gynecology of the University of Bari. The features of women and the reasons that induce these++ acceptance or refusal of the study were valued by an anonymous questionnaire with a precoded reply. RESULTS 92.9% of the women accepted participation in the study. The main reasons for acceptance were: 1) believing that the study was drawn up for women; 2) it was done by expert physicians; 3) it was not done for financial gain. The random standard was the main reason for refusal. CONCLUSIONS With this method we had a very high acceptance, talking over the goals and problems that study aimed to address and to resolve. The chance offered to judge the reliability and competence of physicians is important.

Abstract
Food phytestrogens and prevention of postmenopausal osteoporotic and cardiovascular disease. Phytestrogens are diphenolic compounds, widely found in plants and foods, with structural and biological estrogen-like similarities. Their anti-estrogenic effects are well known and studied due to the possibility to prevent some tumors such as breast and prostate cancer. In menopause they have an estrogenic-like action on lipidic and bone metabolism. Phytestrogens rich foods can positively affect the postmenopausal osteoporotic and cardiovascular pathology.

Abstract
BACKGROUND AND AIMS The increasingly frequent use of mammography for the early diagnosis of breast cancer and the consequent identification of mammary lesions at a preclinical stage raises the fundamental problem of the differential diagnosis between non-suspected non-palpable lesions (NPL) which can therefore be monitored over time and suspected NPL or definite carcinoma requiring histological confirmation and surgical biopsy. The diagnostic accuracy of mammography alone is not sufficiently high to differentiate benign lesions from malignant or strongly suspected ones. The use of surgical biopsy in the event of suspected NPL could be significantly reduced by the use of stereotaxic cytology which would improve the diagnostic accuracy of mammography. METHODS The study refers to 72 suspected NPL undergoing surgical biopsy after having performed stereotaxic cytology on a sample taken with a dedicated mammographic device (Mammotest-TRC). RESULTS The rate of inadequate samples for correct cytological evaluation was 16.1%. Of the 72 NPL undergoing surgical biopsy, 40 (55.5%) were found to be carcinomas and 32 (44.5%) were benign lesions. The sensitivities of mammography alone and cytology alone in identifying infraclinical breast carcinoma were respectively 0.85 and 0.95. If the results of the two methods were evaluated together, the level of sensitivity was 0.98. CONCLUSIONS The use of stereotaxic cytology enables a marked improvement to be achieved in the diagnostic accuracy of mammography for the identification of suspected NPL to undergo surgical biopsy, notably reducing the cost of biopsy (number of benign lesions for each carcinoma diagnosed) and consequent discomfort for patients.

Abstract
Fluorescence-based solution methods have been used to study the binding of the trp repressor of Escherichia coli to a series of oligonucleotides bearing all or partial determinants for high affinity specific binding. The tryptophan, salt concentration and competitor DNA dependence of the binding affinities was examined for these targets. Binding to a fluorescein-labeled 20 base-pair hairpin structure oligonucleotide, which contains a palindromic repressor binding site (GAACTAGTTAACTAGTAC) and is known to bind repressor in a 1 : 1 dimer-DNA complex, resulted in a protein concentration-dependent, competable static quenching of fluorescence in presence of co-repressor, l-tryptophan. The affinity recovered from the fits of these intensity profiles at 100 mM KCl was on the order of 4x10(8) M-1. In absence of co-repressor an increase in intensity at high repressor concentration (>10(-7) M) was observed. The salt concentration dependence of the specific binding of the holo-repressor to this oligonucleotide was approximately half as large as what would be predicted by the number of phosphate contacts in the crystal structures of the complex. Repressor binding to the fluorescein-labeled hairpin 20mer was compared with binding to a rhodamine-labeled 36 base-pair oligonucleotide bearing two inverted structural half-sites GNACT separated by an eight base-pair spacer containing none of the natural intervening sequence. The rather low affinity observed for the 36mer revealed that the intervening sequence in the natural operators contains energetic specificity determinants. Binding to a rhodamine-labeled oligonucleotide bearing a completely non-specific sequence was shown to occur over the same concentration range (>100 nM), regardless of tryptophan concentration, whereas binding to sequences bearing partial specificity ratio between 100 and 1000, depending upon the salt concentration. Even in absence of added KCl, the specificity ratio of trp repressor was greater than 100, implicating a significant free energy contribution from non-electrostatic interaction forces.

Abstract
Mutations in the COL4A5 gene, which encodes the a5 chain of type IV collagen, are found in a large fraction of patients with X-linked Alport syndrome. The recently discovered COL4A6, tightly linked and highly homologous to COL4A5, represents a second candidate gene for Alport syndrome. We analyzed 177 Italian Alport syndrome families by Southern blotting using cDNA probes from both COL4A5 and COL4A6. Nine unrelated families, accounting for 5% of the cases, were found to have a rearrangement in COL4A5. No rearrangements were found in COL4A6, with the exception of a deletion encompassing the 5' ends of both COL4A5 and COL4A6 genes in a patient with Alport syndrome and leiomyomatosis. COL4A5 rearrangements were all intragenic and included 1 duplication and 7 deletions. Polymerase chain reaction (PCR) analysis was carried out to characterize deletion and duplication boundaries and to predict the resulting protein abnormality. The two smallest deletions involved a single exon (exons 17 and 40, respectively), while the largest ones spanned exons 1 to 36. The clinical phenotype of patients in whom a rearrangement in COL4A5 was detected was severe, with progression to end-stage renal failure in juvenile age and hypoacusis occurring in most cases. These data have some important implications in the diagnosis of patients with Alport syndrome.
