Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry.

Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Background
Left ventricular non-compaction cardiomyopathy (LVNC) is associated with poor clinical outcome in childhood, with heart failure, arrhythmias, and embolic events as main clinical manifestations. LV twist has recently been demonstrated having good predictive value in diagnosing LVNC in young patients. However, how LV twist may influence long-term clinical outcome of LVNC children and adolescents is still unknown.
The aim of this study was to analyse a set of echocardiographic parameters to find imaging predictors of worse clinical outcomes in a long-term follow-up of LVNC children and young patients.
Methods
Children and adolescents, followed from May 2012 to June 2020, were enrolled in a retrospective study. All patients underwent 2-dimensional speckle tracking echocardiography and cardiovascular magnetic resonance imaging (1.5 Tesla) at our Institution’s first evaluation.
Death, heart failure hospitalization, aborted sudden cardiac death, ventricular arrhythmias (sustained and non-sustained ventricular tachycardia), and embolisms (i.e. stroke, peripheral arterial embolism and/or pulmonary thromboembolism) were registered and referred to as major adverse cardiovascular events (MACEs).
Results
Recruited for the study were 47 children (mean age: 11.1± 5; age range: 0–18 years). Twenty-three patients fulfilled the cardiovascular magnetic resonance imaging diagnostic criteria for LVNC (LVNC group), while the remaining 24 did not and were included in the LV hypertrabeculation group (LVHT).
They were followed for 4.9 ± 1.0 years, and MACEs were registered. Thirteen children (56% of LVNC, 28% of total) had at least one MACE. Global longitudinal, circumferential and radial strains (GLS, GCS, GRS), LV twist and LVEF resulted being significantly reduced in children with MACEs at follow-up. A multivariable analysis was performed by combining four parameters: LV ejection fraction, GLS, GCS, LV twist. These independent variables were chosen according to univariable analyses and clinical relevance. The results from the analysis demonstrated that LV twist was the only independent predictor (P = 0.033, coeff. B 0.726) of worse clinical outcomes in young patients with LVNC.
Conclusions
LV twist is a promising tool to stratify and predict prognosis in LVNC young patients. Our findings show the importance of LV twist assessment to detect the severity of LVNC and to plan for early clinical intervention.

BACKGROUND
Myocardial work (MW) estimation by pressure-strain loops (PSL) allows a non-invasive evaluation of myocardial performance, as recently demonstrated in adult patients.
Aim of this study is to provide the reference values for global myocardial work index (MWI), constructive work (MCW), wasted work (MWW), and work efficiency (MWE) in a group of healthy children.
METHODS
Assessment of MW was performed using a commercially available software package (Echopac, GE). MW was measured from PSLs areas, derived from non-invasive LVP curves combined with strain acquired speckle tracking echocardiography (STE).
After calculating GLS, values of brachial blood pressure were inserted and the time of valvular events by echocardiography were indicated, then the software was able to measure non-invasive PSLs.
RESULTS
Two-dimensional (2D) standard and speckle-tracking echocardiography were performed in 90 healthy children (mean age 9.9 ±4.9 [1-17] years, females: 57%) together with the assessment of MW by means of PSLs.
Mean ± standard deviation, 5° and 95° percentile values for global MWI, MCW, MWW, and MWE in the whole population were 1769 ± 254 mm Hg, (1354-2193); 2201 ± 290 mm Hg, (1657-2658); 78 ± 47 (29-163) mm Hg%; 96 ± 1.8 (92-99)%, respectively.
CONCLUSIONS
The assessment of MW is feasible in healthy children. This study provides useful 2-dimensional echocardiographic reference ranges for novel indices of non-invasive MW.

Abstract
Abstract
Background
2-dimensional (2-D) left atrial (LA) strain accurately categorizes DD in adults but its diagnostic performance in children is unknown.
Aim of this study is to investigate whether LA strain and strain rate are able to diagnose and classify DD in children with dilated (CMD), hypertrophic (HCM) and restrictive (RCM) cardiomyopathies (CM).
Methods
The study includes 136 children (aged 8.8 ± 6 years): 44 with DCM, 40 with HCM, 7 with RCM and 45 healthy controls (CTRL). They underwent standard echocardiography and 2-D speckle-tracking analyses (LV longitudinal peak systolic strain (LS), LA peak systolic strain and strain rate). Cardiac catheterization was performed within 24 hours after the echocardiographic study in 9 children (mean age 9 ± 7 years) with clinical indication and the LV end-diastolic pressure was measured.
Results
No significant differences in mitral E/A, E/E’, pulmonary S/D ratios and indexed left atrial volumes were observed among the 3 CM groups.
LA peak systolic strain and strain rate values showed a steady and significant decrease with worsening of DD. ROC curves showed area under the curve of 0.976 (p < 0.001) for LA strain and 0.946 (p < 0.001) for LA strain rate, to distinguish CTRL from CMs.
Moreover, univariate regression analysis demonstrated that peak LA strain had a strong significant inverse correlation with invasive LV end-diastolic pressure (r -0.892, p < 0.001). On the other hand, invasive LV end-diastolic pressure had non-significant correlations with E’ avg (r -0.139, p = 0.721), E/E’ avg (r 0.238, p = 0.537), MV DT (r 0.485, p = 0.186) and LAVi (r 0.514, p = 0.157).
Conclusions
LA strain is able to recognize and classify DD in children with cardiomyopathies and accurately correlates with invasive LV end-diastolic pressures.

Abstract
Brain metastases occur in approximately 10-20% of patients with metastatic breast cancer showing a very poor overall survival. Curiously, different molecular subtypes (that show specific gene expression signatures and differential prognostic significance) are associated with different risks for brain metastases development, suggesting that cancer cells harbor specific molecular programs that award them intrinsic advantages to survive in this specific foreign tissue. Emerging data has been revealing that biophysical and/or mechanical properties of the brain extracellular matrix (ECM), along with those of the brain resident cells, play a crucial role in creating the best conditions for survival, colonization and outgrowth of breast cancer cells in this distinct microenvironment. Although several reports show that cancer cells modulate metastatic niches way before they reach the target organ, few data exist for the brain metastatic niche. Indeed, little is known concerning how factors secreted by cancer cells activate brain resident cells and/or modify brain ECM biomechanical properties and how these modifications impact cells´ ability to metastasize the brain. The brain is a particular organ, protected by the blood brain barrier (BBB), and containing exclusive functional units and very special cell types. Additionally, it is the organ with the most singular ECM and biomechanical properties. Thus, this cancer cell-brain metastatic niche interaction must present distinct properties. Consequently, the search for putative molecular markers that modulate the brain pre-metastatic niche, thus promoting the successful metastatic homing of cancer cells, is urgently needed. In this review, we will discuss key aspects regarding breast cancer cells and the brain pre-metastatic niche paracrine communication that is crucial to initiate the metastatic cascade. We will focus on cancer cell`s secretome influence into the brain microenvironment, specifically on its impact on tissue mechanics and on brain resident cells as regulators of the pre-metastatic niche formation, ultimately promoting metastatic colonization.

Abstract
Abstract
Background
Aortic regurgitation (AR) continues to be an important cause of morbidity and mortality, particularly in paediatric patients. In the paediatric population the prevalence of AR has increased, also due to expanded use of new surgical and hemodynamic procedures. While echocardiographic parameters are well established for the adults, there are no clear cut-off values to assess AR severity in children. Cardiac magnetic resonance (CMR) imaging is widely used to assess diagnostic and prognostic information and is considered a “gold standard” for a quantitative evaluation of the aortic regurgitation.
Purpose
The aim of the study is to assess which echo parameters can accurately define AR severity as assessed by CMR in paediatric patients.
Methods
A total of 36 paediatric patients (12±3,2 years of age, age range 6–18) with different degree of AR underwent echocardiographic assessment within an average of 25 days from CMR (no therapeutic changes were made in this period). Heart rate and arterial blood pressure were comparable during echo and CMR. CMR included phase-contrast velocity-encoded imaging for the measurement of regurgitant fraction (RF) at the sinotubular junction. Severe AR was defined as RF>33%. Echocardiographic evaluation included vena contracta (VC), pressure half time (PHT), the ratio between the AR jet and the LVOT diameter (jet/LVOT), presence of holodiastolic reversal flow in abdominal aorta (abdAo), the ratio between the velocity-time integral of the reversal flow over the forward flow in descending aorta (dAo-ratio).
Results
Among the echo parameters studied, the strongest predictor of severe aortic regurgitation, as assessed by CMR with RF, was dAo-ratio. ROC curve showed, for a cut-off >0.38: AUC 0.882, p<0.0001, sensitivity 71.4%, specificity 96.6%. Correlation coefficient between dAo-ratio and RF was R=0.9183 with a p<0.0001.
ROC curves were performed for all the echo parameters. PHT <410 ms: AUC 0,800, p=0,0001, sensitivity 100%, specificity 62,1%; VC >4 mm: AUC 0.783, p=0.0004, sensitivity 71.4%, specificity 72.4%; jet/LVOT >0.35: AUC 0.813, p=0,0002, sensitivity 71,4%, specificity 86,2%; abdAo =1: AUC 0,734, p 0,026, sensitivity 57,1%, specificity 89,7%.
dAo-ratio: measurement and statistics
Conclusions
Our findings suggest that dAo-ratio is a strong marker of severe aortic regurgitation in the paediatric population. This parameter should be routinely added in the standard echo evaluation of paediatric patients with aortic regurgitation.

Abstract
Brettanomyces is a yeast species responsible for wine and cider spoilage, producing volatile phenols that result in off-odors and loss of fruity sensorial qualities. Current commercial detection methods for these spoilage species are liable to frequent false positives, long culture times and fungal contamination. In this work, an interdigitated (IDE) biosensor was created to detect Brettanomyces using immunological reactions and impedance spectroscopy analysis. To promote efficient antibody immobilization on the electrodes' surface and to decrease non-specific adsorption, a Self-Assembled Monolayer (SAM) was developed. An impedance spectroscopy analysis, over four yeast strains, confirmed our device's increased efficacy. Compared to label-free sensors, antibody biosensors showed a higher relative impedance. The results also suggested that these biosensors could be a promising method to monitor some spoilage yeasts, offering an efficient alternative to the laborious and expensive traditional methods.

Abstract
Physical forces mediated by cell-cell adhesion molecules, as cadherins, play a crucial role in preserving normal tissue architecture. Accordingly, altered cadherins' expression has been documented as a common event during cancer progression. However, in most studies, no data exist linking pro-tumorigenic signaling and variations in the mechanical balance mediated by adhesive forces. In breast cancer, P-cadherin overexpression increases in vivo tumorigenic ability, as well as in vitro cell invasion, by activating Src family kinase (SFK) signalling. However, it is not known how P-cadherin and SFK activation impact cell-cell biomechanical properties. In the present work, using atomic force microscopy (AFM) images, cell stiffness and cell-cell adhesion measurements, and undirected graph analysis based on microscopic images, we have demonstrated that P-cadherin overexpression promotes significant alterations in cell's morphology, by decreasing cellular height and increasing its area. It also affects biomechanical properties, by decreasing cell-cell adhesion and cell stiffness. Furthermore, cellular network analysis showed alterations in intercellular organization, which is associated with cell-cell adhesion dysfunction, destabilization of an E-cadherin/p120ctn membrane complex and increased cell invasion. Remarkably, inhibition of SFK signaling, using dasatinib, reverted the pathogenic P-cadherin induced effects by increasing cell's height, cell-cell adhesion and cell stiffness, and generating more compact epithelial aggregates, as quantified by intercellular network analysis. In conclusion, P-cadherin/SFK signalling induces topological, morphological and biomechanical cell-cell alterations, which are associated with more invasive breast cancer cells. These effects could be further reverted by dasatinib treatment, demonstrating the applicability of AFM and cell network diagrams for measuring the epithelial biomechanical properties and structural organization.

Abstract
The experimental flow curves of four different yield-stress fluids with different interparticle interactions are studied near the jamming concentration. By appropriate scaling with the distance to jamming all rheology data can be collapsed onto master curves below and above jamming that meet in the shear-thinning regime and satisfy the Herschel-Bulkley and Cross equations, respectively. In spite of differing interactions in the different systems, master curves characterized by universal scaling exponents are found for the four systems. A two-state microscopic theory of heterogeneous dynamics is presented to rationalize the observed transition from Herschel-Bulkley to Cross behavior and to connect the rheological exponents to microscopic exponents for the divergence of the length and time scales of the heterogeneous dynamics. The experimental data and the microscopic theory are compared with much of the available literature data for yield-stress systems.

Abstract
Central venous catheters (CVC) are commonly used in clinical practice to improve a patient's quality of life. Unfortunately, there is an intrinsic risk of acquiring an infection related to microbial biofilm formation inside the catheter lumen. It has been estimated that 80 % of all human bacterial infections are biofilm-associated. Additionally, 50 % of all nosocomial infections are associated with indwelling devices. Bloodstream infections account for 30-40 % of all cases of severe sepsis and septic shock, and are major causes of morbidity and mortality. Diagnosis of bloodstream infections must be performed promptly so that adequate antimicrobial therapy can be started and patient outcome improved. An ideal diagnostic technology would identify the infecting organism(s) in a timely manner, so that appropriate pathogen-driven therapy could begin promptly. Unfortunately, despite the essential information it provides, blood culture, the gold standard, largely fails in this purpose because time is lost waiting for bacterial or fungal growth. This work presents a new design of a venous access port that allows the monitoring of the inner reservoir surface by means of an impedimetric biosensor. An ad-hoc electronic system was designed to manage the sensor and to allow communication with the external receiver. Historic data recorded and stored in the device was used as the reference value for the detection of bacterial biofilm. The RF communication system sends an alarm signal to the external receiver when a microbial colonization of the port occurs. The successful in vitro analysis of the biosensor, the electronics and the antenna of the new indwelling device prototype are shown. The experimental conditions were selected in each case as the closest to the clinical working conditions for the smart central venous catheter (SCVC) testing. The results of this work allow a new generation of this kind of device that could potentially provide more efficient treatments for catheter-related infections.

Abstract
The pancreatic islets of Langerhans are highly vascularized structures scattered throughout the pancreas that contain a capillary network 5-10 times denser than that of the exocrine pancreas. A simple method for three-dimensional (3D) analysis of this intricate intraislet vasculature has been difficult because of the intrinsic opacity of the pancreas. We developed a whole-mount imaging technique that allows relatively easy visualization of the islet vasculature. In combination with confocal microscopy and the use of 3D imaging software, we were able to readily reconstruct the 3D architecture of an islet, allowing delineation of the islet volume, length of the intraislet vessels, and the number of vessel branch-points. This technique allows for straightforward 3D image analysis that may help toward understanding islet function.

Abstract
Paternal behaviour and pair-bond formation are defining characteristics of social monogamy. However, in comparison to pair-bonding, the endocrine factors associated with the male care of young are not well studied. In the present study, plasma concentrations of oxytocin, vasopressin and corticosterone (CORT) were measured in reproductively naïve male prairie voles as a function of exposure to an infant or control manipulations (i.e. handling or exposure to a wooden dowel). Plasma oxytocin concentrations were transiently elevated within 10 min of pup exposure. Although plasma CORT concentration typically increases after handling, after 10 min of pup exposure, the concentration of plasma CORT was not increased, suggesting an attenuation of CORT release by pup exposure. Group differences in the concentrations of plasma hormones were no longer detected at 20 or 60 min after treatment. These patterns of rapid change in the concentrations of plasma oxytocin and CORT were observed in both juvenile and adult males but not detected after control procedures. Plasma vasopressin, assessed only in adult males, did not vary as a function of pup exposure or other manipulations. In the paraventricular nucleus of the hypothalamus, pup exposure also increased activation (as assessed by the measurement of c-Fos) of neurones that stained for either oxytocin or vasopressin, whereas it decreased c-Fos expression in neurones stained for corticotrophin-releasing hormone. In addition, brief pup exposure (20 min) facilitated subsequent partner preference formation when alloparental males and pup attackers were considered as a group. In the context of other studies, these data support the hypothesis that neuroendocrine changes associated with male alloparental behaviour are related to those implicated in pair-bonding.

Abstract
The goal of the present work was to evaluate the correlation of glucose transporter 1 (GLUT1) and carbonic anhydrase IX (CAIX) with the monocarboxylate transporters 1 (MCT1) and 4 (MCT4) and their chaperone, CD147, in breast cancer. The clinico-pathological value of GLUT1 and CAIX was also evaluated. For that, we analysed the immunohistochemical expression of GLUT1 and CAIX, in a large series of invasive breast carcinoma samples (n=124), previously characterized for MCT1, MCT4 and CD147 expression. GLUT1 expression was found in 46% of the cases (57/124), while CAIX was found in 18% of the cases (22/122). Importantly, both MCT1 and CD147, but not MCT4, were associated with GLUT1 and CAIX expression. Also, GLUT1 and CAIX correlated with each other. Concerning the clinico-pathological values, GLUT1 was associated with high grade tumours, basal-like subtype, absence of progesterone receptor, presence of vimentin and high proliferative index as measured by Ki-67. Additionally, CAIX was associated with large tumour size, high histological grade, basal-like subtype, absence of estrogen and progesterone receptors and presence of basal cytokeratins and vimentin expression. Finally, patients with CAIX positive tumours had a significantly shorter disease-free survival. The association between MCT1 and both GLUT1 and CAIX may result from hypoxia-mediated metabolic adaptations, which confer a glycolytic, acid-resistant and more aggressive phenotype to cancer cells.

Abstract
BACKGROUND Changes in junctional catenin expression may compromise cadherin-mediated adhesion, increasing cell malignant properties such as invasive and metastatic abilities. Altered expression of alpha-, beta-, gamma- and p120-catenin has been reported to be associated with E-cadherin loss or decreased expression, in both breast carcinomas and breast cancer cell lines. AIMS AND METHODS To investigate the expression and subcellular localisation of p120- and beta-catenin in a series of human invasive breast carcinomas, and correlate it with biological markers and clinicopathological parameters. RESULTS Both catenins frequently exhibited a reduced membranous or cytoplasmic staining pattern. These alterations were significantly correlated with lack of both E-cadherin and oestrogen receptor-alpha expression. It was possible to associate the expression of beta-catenin with histological grade, tumour size and nodal status, suggesting a relevant role for this catenin as a prognostic factor. The majority of E- and P-cadherin co-expressing tumours were related to cytoplasmic expression of p120-catenin; in this group of breast carcinomas, patient survival was poor. CONCLUSION Results indicate that p120-catenin cytoplasmic accumulation may play an important role in mediating the oncogenic effects derived from P-cadherin aberrant expression, including enhanced motility and invasion, particularly in tumours which maintain E-cadherin expression.

Abstract
AIM Hereditary diffuse gastric cancer (HDGC) is a cancer susceptibility syndrome caused by E-cadherin germline mutations. One-third of these mutations are of the missense type, representing a burden in genetic counselling. A new germline missense mutation (P373L) was recently identified in a HDGC Italian family. The present work aimed at addressing the disease-causative nature of the P373L mutant. METHODS Assessment of the P373L mutation effect was based on cell aggregation and invasion assays. LOH analysis at the E-cadherin locus, search for somatic E-cadherin mutations and for promoter hypermethylation were performed to identify the mechanism of inactivation of the E-cadherin wild-type allele in the tumour. RESULTS In vitro the P373L germline mutation impaired the E-cadherin functions. E-cadherin promoter hypermethylation was observed in the tumour of the P373L mutation carrier. CONCLUSION We conclude that the combination of clinical, in vitro and molecular genetic data is helpful for establishing an accurate analysis of HDGC-associated CDH1 germline missense mutations and subsequently for appropriate clinical management of asymptomatic mutation carriers.

Abstract
OBJECTIVE To study P-cadherin aberrant expression as a possible marker for cervical adenocarcinomas in cytological samples. METHODS We studied P-cadherin immunoexpression in liquid-based cervical cytology samples of biopsy-proven cervical lesions. RESULTS We found a statistically significant correlation between P-cadherin expression and a cytological diagnosis of malignancy, either glandular or squamous (P < 0.0001). Twenty-two of 33 malignant cases showed P-cadherin membrane staining. None of the 30 benign cases tested showed membrane staining, but three of them displayed an aberrant nuclear P-cadherin expression. CONCLUSIONS We concluded that P-cadherin can be used to discriminate between malignant and benign cervical cytological specimens, but not to discriminate glandular from squamous lesions.

Abstract
P-cadherin is a classical cadherin expressed by myoepithelial cells in mammary tissue. Its expression in human breast cancer has been associated with aggressive tumour behaviour. To analyse the possible role of P-cadherin in canine mammary carcinogenesis, its expression was examined immunohistochemically in 82 samples of normal (n=2), hyperplastic (n=11) and neoplastic (n=69) canine mammary tissues. In normal and hyperplastic canine mammary glands, P-cadherin was restricted to myoepithelial cells, usually at sites of cell-to-cell contact. In tumour tissues, however, P-cadherin expression was observed in both epithelial and myoepithelial cells, with a cytoplasmic pattern of cellular distribution. Aberrant epithelial P-cadherin immunolabelling was found in 19/44 (43%) benign tumours and in 16/25 (64%) malignant tumours (P<0.001). In malignant tumours, a significant correlation between P-cadherin expression intensity and histological type was observed (P<0.05).

Abstract
BACKGROUND Systemic lupus erythematosus has a wide spectrum of immunological and clinical manifestations. Its course is characterised by exacerbations which may result in mortality or morbidity to vital organs/systems. OBJECTIVE To determine clear and early prognostic markers to avoid further complications. METHODS 245 adult patients diagnosed between January 1978 and March 2001 were studied. Clinical manifestations and laboratory findings both at onset and during the clinical course were collected. The number, type, and severity of the flares were also noted. Statistical analyses between disease features at onset, subsequent flares, and mortality were performed. RESULTS 239 patients entered the study. Their mean age at onset was 30 years. The mean time between onset and diagnosis was 36 months and the mean evolution time was 114 months. 205 patients developed 915 flares; 205 (22.4%) of these flares were major flares, and affected 110 patients. Cardiac, neurological, or renal affection at onset were associated with a higher probability of developing cardiac (p=0.022), neurological (p<0.001), and renal (p<0.001) exacerbations, respectively, during the evolution. Lupus anticoagulant (LA) and anticardiolipin antibodies (aCL) were predictors of stroke (aCL, p=0.000; LA, p=0.001). Age at diagnosis (p=0.003) and valvular disease at onset (p=0.008) were independent predictors of low survival. CONCLUSIONS Renal, cardiac, or neurological involvement and the presence of LA or aCL positivity at onset were predictors of renal, cardiac, or neurological flares, respectively. Age and valvular involvement at onset were found to be independent adverse outcome predictors for low survival.

Abstract
Evidence suggests the periaqueductal gray (PAG) is involved in the integration of behavioral and autonomic components of affective behavior. Our laboratory has shown that electrical stimulation of the ventrolateral periaqueductal gray (vl PAG) versus the dorsolateral periaqueductal gray (dl PAG), in the rabbit, elicits two distinct behavioral/cardiorespiratory response patterns. Furthermore, evidence suggests that the amygdaloid central nucleus (ACe) may influence cardiovascular activity during emotional states. The purpose of this study was to delineate the topography and determine the origin of forebrain projections to the PAG and the ACe, as well as commonalties and differences in the pattern of afferents. Examination of common afferents may lend insights into their function as components of a forebrain system regulating autonomic activity during emotional states. Separate retrograde tracers were injected into functional subdivisions of the PAG and the ACe in rabbits. PAG injections led to neuronal labeling in numerous cortical regions including the ipsilateral medial prefrontal and insular cortices. Additionally, bilateral labeling was observed in several hypothalamic nuclei including the paraventricular nucleus, the dorsomedial nucleus and the ventromedial nucleus as well as the region lateral to the descending column of the fornix. Sparse labeling was also seen in various basal forebrain regions, thalamic nuclei and amygdaloid nuclei. Many of these regions were also labeled following injections in the ACe. Although double-labeled cells were never observed, afferents to the ACe were often proximal to PAG afferents. Implications of these findings are discussed in terms of two functionally distinct behavioral/cardiovascular response patterns.

Abstract
Interleukin-1 (IL-1) produced in peripheral blood mononuclear cell (PBMC) cultures or added exogenously has been shown to upregulate HIV expression in vitro. Inhibition of IL-1 in HIV-infected individuals may inhibit HIV activation and slow disease progression. Recombinant human IL-1 receptor (rHu-IL-1R), the soluble extracellular portion of the human type I IL-1 receptor, inhibits HIV expression in acutely infected primary PBMCs and in the chronically infected promonocytic cell line, U1. We, therefore, conducted a phase I/II trial of the soluble rHu-IL-1R in HIV-1-infected individuals with CD4 T cell counts <300/microl to evaluate its safety and activity. Twelve evaluable patients were enrolled at three rHu-IL-1R dose levels:125 (n=3), 500 (n=3), and 1250 (n=6) microg/m2 per dose by subcutaneous (s.c.) injection three times a week for 8 weeks, followed by a 4 week observation period. rHu-IL-1R was safe and well tolerated. There were no deaths, no treatment-related grade 3/4 events, and no premature study discontinuations because of adverse events. The maximum tolerated dose was not reached. Seven patients reported improvements in one or more symptoms, including weight gain (3), improved energy level (4), decreased diarrhea (1), decreased night sweats (1), improvement in psoriatic arthritis (1), and improvement in a nonspecific chronic diffuse skin rash (1). Of 3 evaluable patients with Kaposi's sarcoma, 1 remained stable and 2 showed minimal progression. No consistent trends in absolute CD4 counts or percentages, quantitative HIV cultures, or serum p24 antigen, beta2-microglobulin, or triglyceride levels were observed. rHu-IL-1R is safe and well tolerated at the doses tested but induced no consistent changes in objective markers of HIV disease. Symptomatic improvements will require confirmation in randomized, placebo-controlled trials.
