Abstract
BACKGROUND AND OBJECTIVES The ideal timing of tranexamic acid administration in total knee arthroplasty with tourniquet remains unclear. Our primary objective was to prove if administering it before surgical incision, instead of before releasing the tourniquet, reduces postoperative bleeding. A second objective was to determine whether a second dose reduces post-operative bleeding. MATERIAL AND METHODS A prospective, double-blind clinical trial was performed on 212 patients scheduled for total knee arthroplasty. They were randomised into 4 groups. Tranexamic acid was administered before the surgical incision in "pre-induction groups" (1 and 2), and just before the tourniquet release in "pre-release groups" (3 and 4). Groups 2 and 4 received a second dose 3h post-surgery. Main outcome was postoperative bleeding (visible blood loss and calculated total bleeding). Secondary outcomes were haemoglobin variations, complications and transfusion rate. RESULTS The mean calculated total bleeding was 1563ml (95%CI: 1445-1681) in preinduction groups versus 1576ml (95%CI: 1439-1713) in pre-release groups (P=0.9); 1579ml (95%CI: 1452-1706) in single-dose groups versus 1559ml (95%CI: 1431-1686) in double-dose groups (P=0.82). One patient was transfused. The mean haemoglobin at discharge was 10.4g/dl (95%CI: 10.2-10.7) in singledose groups versus 10.8 (95%CI: 10.6-11.1) in double-dose groups (P=0.06). CONCLUSIONS There were no differences in bleeding or transfusion regarding the time of tranexamic acid administration. The second dose had not impact on outcomes.

Abstract
INTRODUCTION when faced with a chronic digital injury, the differential diagnosis between osteomyelitis or primary tumor is raised. Coexistence between osteomyelitis and epidermoid bone cyst is not uncommon. MATERIAL AND METHODS in this article, we describe two cases of epidermoid cysts in distal phalanx of the hand associated with osteomyelitis and a review of the literature is presented. RESULTS both osteomyelitis and epidermoid bone cyst have been related to the presence of previous trauma at the site of the lesion, nail alterations and chronic phlogotic signs, so it is important to reach a diagnosis of certainty through an anatomopathological study and to perform a good surgical debridement to ensure the healing of both entities. CONCLUSIONS surgical debridement associated with curettage and filling of the bone defect with bone substitute with antibiotic is a good therapeutic option in the treatment of these lesions.

Abstract
Abstract
Background
Right ventricular (RV) systolic function is determinant in the evaluation of patients with severe tricuspid regurgitation (TR). Timely detection of RV dysfunction with conventional 2D echocardiography is challenging. RV strain has emerged as an accurate and sensitive tool for evaluation of RV function with the capability of detecting subclinical RV dysfunction.
Purpose
This study was aimed to evaluate the prognostic value of RV strain parameters in consecutive stable patients with severe TR.
Methods
Consecutive patients in stable clinical status with at least severe TR (severe, massive or torrential TR) evaluated in the Heart Valve Clinic following a comprehensive clinical protocol were included. Patients with previous episodes of heart failure or scheduled for TV intervention were excluded. RV systolic function was measured with conventional echocardiographic indices (RV fractional area change [FAC], tricuspid annular plane systolic excursion [TAPSE], DTI S wave [`S]) and with Speckle-tracking echocardiography (STE) derived automatic peak global and free wall longitudinal strain (RV-GLS and RV-FWLS respectively) using the EPIQ system (Philips Medical Systems, Andover, Massachusetts). A combined endpoint of hospital admission due to heart failure (HF) or all-cause mortality was defined. The interobserver variability of RV strain was assessed in 20 randomly selected patients.
Results
A total of 176 patients were included in this study. Strain parameters detected higher percentage of RV dysfunction compared to conventional indices (figure 1). After a median follow-up of 28 months (IQR: 15–48 months), n=65 patients (37%) reached the combined endpoint. 65 (37%) were admitted for right heart failure and 8% of the population (n=14) died. Cumulative event-free survival was significantly worse in patients with impaired RV-GLS and RV-FWLS. Conventional indices of RV systolic function were not associated with outcomes (p>0.05 for all). In a multivariable analysis (in a model including NYHA class, BNP values, biplane VC, RV end-diastolic area, and RV-FWLS), RV-FWLS was an independent predictors of heart failure and CV mortality (figure 1 and 2; LR χ2: 40.2, p<0.001). Inter-observer agreements for RV strain values were high (intraclass correlation coefficient for RV-GLS and RV-FWLS, r=0.96 and r=0.98 respectively)
Conclusion
Clinical outcomes demonstrate that RV strain parameters are superior to conventional indices of RV function in patients with isolated ≥ severe TR and absence of previous episodes of heart failure. Among all parameters of RV function, RV-FWLS is the strongest independent predictor of mortality and HF.

Abstract
Abstract
Background
Optimal management of severe tricuspid regurgitation (TR) remains controversial. While right ventricular systolic function is an established prognostic marker of outcomes, the potential role of right atrial (RA) function is unknown.
Purpose
This study was aimed to describe RA function by 2D speckle tracking echocardiography (STE) in severe TR and to evaluate its potential association with cardiovascular outcomes
Methods
Consecutive patients with at least severe TR (severe, massive or torrential TR) evaluated in the Heart Valve Clinic following a comprehensive clinical protocol were included. Consecutive control subjects and patients with permanent atrial fibrillation (AF) were included for comparison. RA function was measured with 2D-STE and 3 components of RA function were calculated: reservoir (RASr), conduit (RAScd) and contractile (RASct) RA values using an automatic 2D strain analytical software (AutoStrain, Philips Medical Systems the EPIQ system, Figure 1). A combined endpoint of hospital admission due to heart failure (HF) or all-cause mortality was defined. The interobserver variability of RA strain was assessed in 30 randomly selected subjects (20 TR+5 AF+5 controls).
Results
A total of 176 patients with severe TR, 20 AF patients and 20 controls subjects were included in this study. Patients with at least severe TR showed lower RASr and RAScd compared to controls and to AF patients (Figure 1 and Table 1, p<0.05). After a median follow-up of 28 months (IQR: 15–48 months), n=65 patients with severe TR (37%) reached the combined endpoint. 65 (37%) were admitted for right heart failure and 8% of the population (n=14) died. Patients with events showed lower values of RASr and RAScd (p<0.01 for both). Between both parameters RASr was more strongly associated with outcomes compared to RAScd (AUC 0.74 vs. 0.65, p<0.01). RASr was an independent predictor of heart failure and all cause mortality adjusted by additional imaging prognostic parameters in a multivariable analysis (biplane vena contracta, RV end-diastolic area, and RV-free wall longitudinal strain [LR χ2: 49.7, p<0.001]). RA area or volume was not associated with outcomes. A cut-off value of RASr of <9.4% held the best accuracy to predict outcomes (adjusted HR 3.2 (1.81–5.84), p<0.001, Figure 1). Inter-observer agreements for RA strain values across the whole cohort were high (intraclass correlation coefficient for RASr, RAScd and RASct, r=0.95, r=0.86, r=0,92 respectively)
Conclusions
Evaluation of RA function by 2D-STE is feasible, reproducible and is an independent predictor of heart failure and all-cause mortality in patients with at least severe TR.

Abstract
Abstract
Background
Significant Tricuspid Regurgitation (TR) is associated with increased morbi-mortality. Clinical evaluation of TR patients is challenging.
Purpose
To establish a new clinical classification specific for patients with TR, the 4A classification, and evaluate its performance on prognosis.
Methods
Consecutive patients with isolated at least severe TR and absence of episodes of heart failure (HF) evaluated in the Heart Valve Clinic were included. Signs and symptoms of Asthenia, Ankle swelling, Abdominal pain or distention and/or Anorexia where registered, follow up was performed every 6 months. 4A classification ranged from A0 (no A) to A4 (three or four A's present). A combined endpoint of hospital admission due to right HF and cardiovascular mortality was defined.
Results
135 patients with significant TR between 2016 and 2021 were included (69% females, mean age was 78±7 years). During a median follow-up of 26 months (IQR: 10–41 months), n=53 patients (39%) reached the combined endpoint. 52 (38%) admitted for heart failure and 11% (n=15) died. At baseline 94% of patients were in NYHA I or II whereas 24% presented A2 or A3. The presence of A2 or A3 showed a high incidence of events (figure). The change in 4A class and GGT remained independent predictor of HF and cardiovascular mortality (adjusted HR per unit of change of 4A class 1.95 [1.37–2.77], p<0.001)
Conclusions
For the first time, we show the use of a new clinical classification, specific for patients with TR based on signs and symptoms of right HF that is prognostic of events.

Abstract
Abstract
Background
Right ventricular (RV) performance is key in the management of patients with severe tricuspid regurgitation (TR); detection of RV dysfunction is crucial to identify on time patients that benefit from valve intervention. Conventional parameters of RV function by 2D echocardiography are influenced by changes on preload conditions and can remain unaffected until late stages of the disease. The right atrium (RA) has an important role in modulating RV filling and RA performance is impaired in severe TR. Potentially, an index that combines RV and RA function may reflect a broader view of the effects of severe TR in right heart function.
Purpose
1) to evaluate the clinical utility of combining RV and RA strain for prediction of CV outcomes and 2) to design a novel index by Speckle-tracking echocardiography (STREI index) that integrates RA and RV information
Methods
Consecutive patients with at least severe TR (severe, massive or torrential TR) evaluated in the Heart Valve Clinic following a comprehensive clinical protocol were included. Consecutive control subjects and patients with permanent atrial fibrillation (AF) were included for comparison. Reservoir RA strain (RASr) and RV-free wall longitudinal strain (RV-FWLS) analysis were performed using novel, automated 2D strain analytical software (AutoStrain, Philips Medical Systems the EPIQ system, Figure 1). Novel STREI index was calculated with the formula: [2 × RV-FWLS] + RASr in absolute numbers.
A combined endpoint of hospital admission due to heart failure (HF) or all-cause mortality was defined. The interobserver variability of RA strain was assessed in 30 randomly selected subjects (20 TR+5 AF+5 controls).
Results
A total of 176 patients with severe TR, 20 AF patients and 20 controls subjects were included in this study. Patients with TR showed lower STREI values compared to controls and to AF patients (TR vs. controls vs. AF: 55±18 vs. 116±12 vs. 70±13, p<0,001). After a median follow-up of 28 months (IQR: 15–48 months), n=65 patients with severe TR (37%) reached the combined endpoint. Patients with both abnormal strains (abnormal RV-FWLS and abnormal RASr strain) showed a significantly higher rate of events (Figure 2A). In a multivariable analysis, STREI index was an independent predictor of HF and mortality adjusted by vena contracta, RV end-diastolic area, NYHA class and BNP values (LR χ2: 46,1, p<0,001). A cut off value of STREI index <50% held the best accuracy to predict outcomes. An abnormal STREI index was associated with 6,1-fold increased risk of HF or death (HR 6,9 (3,9–12,3), p<0,001, Figure 2B) Inter-observer agreements for STREI values were high (intraclass correlation coefficient = 0,96).
Conclusion
STREI index is a feasible and reproducible new parameter of RV performance that independently predicts outcomes in patients with severe TR. Randomized studies should confirm its potential to identify those patients that benefit from earlier valve interventions.

Abstract
Hybrid hydrogels composed of chitosan (CS) and hyaluronic acid (HA) and collagen (Coll) were prepared by polyelectrolyte complex self-assembly. These scaffolds displayed a good intermingling of the polymeric chains, with porosities above 80% and good interconnected structures with pore sizes lying between 30–115 μm. The ionic interactions between CS and HA make the scaffolds have larger storage modulus and longer LVR regions than their pure counterparts. Both quantities progressively decrease as the HA and Coll concentrations in the formulation rise. These hybrid hydrogels showed good swelling extents from ca. 420 to ca. 690% and suitable resistance to enzymatic degradation, which was slightly lower for scaffolds containing CS to larger extents or Coll in the formulation. All scaffolds were largely cytocompatible and allowed the proliferation of both mouse fibroblast and human keratinocytes with their infiltration inside, thus becoming optimal matrices for intended tissue engineering applications as well as transdermal drug delivery depots. Hybrid scaffolds were obtained by polyelectrolyte ionic self-assembly Scaffolds were largely porous with suitable pore sizes for cell proliferation Scaffolds showed exceptional swelling and good resistance to enzymatic attack They were nontoxic and enabled cell proliferation and infiltration inside the scaffold

Abstract
Is it possible to find deterministic relationships between optical measurements and pathophysiology in an unsupervised manner and based on data alone? Optical property quantification is a rapidly growing biomedical imaging technique for characterizing biological tissues that shows promise in a range of clinical applications, such as intraoperative breast-conserving surgery margin assessment. However, translating tissue optical properties to clinical pathology information is still a cumbersome problem due to, amongst other things, inter- and intrapatient variability, calibration, and ultimately the nonlinear behavior of light in turbid media. These challenges limit the ability of standard statistical methods to generate a simple model of pathology, requiring more advanced algorithms. We present a data-driven, nonlinear model of breast cancer pathology for real-time margin assessment of resected samples using optical properties derived from spatial frequency domain imaging data. A series of deep neural network models are employed to obtain sets of latent embeddings that relate optical data signatures to the underlying tissue pathology in a tractable manner. These self-explanatory models can translate absorption and scattering properties measured from pathology, while also being able to synthesize new data. The method was tested on a total of 70 resected breast tissue samples containing 137 regions of interest, achieving rapid optical property modeling with errors only limited by current semi-empirical models, allowing for mass sample synthesis and providing a systematic understanding of dataset properties, paving the way for deep automated margin assessment algorithms using structured light imaging or, in principle, any other optical imaging technique seeking modeling. Code is available.

Abstract
Purpose:To carry out cultural adaptation and validation into Spanish of the 7-items self-administered GAD-7 scale; a tool to identify probable patients with Generalized Anxiety Disorder (GAD).Material and methods:The adaptation, conducted by an eight-expert panel, was performed by means of a conceptual equivalence process, including forward and backward translations in duplicate to the original language. The content validity was assessed by inter-ratter-agreement (item-goal congruence index of Rovinelli-Hambleton). The adapted version was administered to patients with GAD according to DSM IV criteria and their respective controls, matched by age and sex, who were recruited at random in Mental Health and Primary Care centres to verify scale feasibility and potential understanding problems.Results:The inter-ratter reliability confirmed the correct inclusion of items in the corresponding dimension of GAD. The study sample consisted of 8 patients with GAD and 8 controls (62.5% male), mean age 50.38 years (SD=16.76). The average time to completion was 2’30”. No items of the scale were left blank. Floor and ceiling effects were negligible. No patients with GAD had to be assisted to fill in the questionnaire. All the items, except item 5 (p=0,105), showed statistically significant differences among groups (p< 0.05).Conclusion:After the adaptation process, a Spanish version of the GAD-7 scale was obtained, confirming its content validity, pertinence and adequacy of items in the Spanish cultural context. The brief time to completion precluded a fast and easy self-administration in the routine medical practice to promptly detect probable cases of GAD.

Abstract
Many well-known algorithms for the color enhancement of hyperspectral measurements in biomedical imaging are based on statistical assumptions that vary greatly with respect to the proportions of different pixels that appear in a given image, and thus may thwart their application in a surgical environment. This article attempts to explain why this occurs with SVD-based enhancement methods, and proposes the separation of spectral enhancement from analysis. The resulting method, termed affinity-based color enhancement, or ACE for short, achieves multi- and hyperspectral image coloring and contrast based on current spectral affinity metrics that can physically relate spectral data to a particular biomarker. This produces tunable, real-time results which are analogous to the current state-of-the-art algorithms, without suffering any of their inherent context-dependent limitations. Two applications of this method are shown as application examples: vein contrast enhancement and high-precision chromophore concentration estimation.

Abstract
BACKGROUND Improving the water solubility of hydrophobic drugs, increasing their accumulation in tumor tissue and allowing their simultaneous action by different pathways are essential issues for a successful chemotherapeutic activity in cancer treatment. Considering potential clinical application in the future, it will be promising to achieve such purposes by developing new biocompatible hybrid nanocarriers with multimodal therapeutic activity. RESULTS We designed and characterised a hybrid nanocarrier based on human serum albumin/chitosan nanoparticles (HSA/chitosan NPs) able to encapsulate free docetaxel (DTX) and doxorubicin-modified gold nanorods (DOXO-GNRs) to simultaneously exploit the complementary chemotherapeutic activities of both antineoplasic compounds together with the plasmonic optical properties of the embedded GNRs for plasmonic-based photothermal therapy (PPTT). DOXO was assembled onto GNR surfaces following a layer-by-layer (LbL) coating strategy, which allowed to partially control its release quasi-independently release regarding DTX under the use of near infrared (NIR)-light laser stimulation of GNRs. In vitro cytotoxicity experiments using triple negative breast MDA-MB-231 cancer cells showed that the developed dual drug encapsulation approach produces a strong synergistic toxic effect to tumoral cells compared to the administration of the combined free drugs; additionally, PPTT enhances the cytostatic efficacy allowing cell toxicities close to 90% after a single low irradiation dose and keeping apoptosis as the main cell death mechanism. CONCLUSIONS This work demonstrates that by means of a rational design, a single hybrid nanoconstruct can simultaneously supply complementary therapeutic strategies to treat tumors and, in particular, metastatic breast cancers with good results making use of its stimuli-responsiveness as well as its inherent physico-chemical properties.

Abstract
Abstract
Background
Transcatheter valve-in-valve (tVIV) implantation for degenerated aortic bioprosthesis has become an alternative to surgical aortic valve replacement (sAVR) in the past few years. However, some concerns have been raised regarding to the long-term safety and efficacy of tVIV. The objective was to compare the clinical and echocardiographic outcomes of tVIV implantation with redo cAVR.
Methods
After an extensive search of PubMed we included 7 observational studies (3 used propensity score matching) comparing tVIV versus sAVR in 762 patients The primary endpoint was all-cause mortality determined from the longest available survival data. Other outcomes of interest were stroke, permanent pacemaker implantation, paravalvular leak, hospital stay and postoperative aortic valve gradient. The review was conducted according to the MOOSE recomendations. Der Simonian and Laird random effects model was used to estimate summary measures and their 95% CI.
Results
Patients in the tVIV group were significantly older (78 vs 73 y.o.) and had a higher baseline risk compared to those in the re-sAVR group (Euroscore 19.7 vs 14.3). There was no statistical difference in procedural or 30-day mortality 5.4% vs 5.3% in tVIV and sAVR, respectively (RR 0.98, 95% CI 0.54–1.80; p=0.96], and long-term mortality (from 6 month to 5 years) 18.7% versus 16.5% (RR 1.13, 95% CI 0.80–1.60; P=0.50). The risk of stroke was similar (1.5% in tVIV vs 2.4% in sAVR, p=0.47). tVIV was associated with a significantly lower rate of permanent pacemaker implantations 6.9% vs 12.1% (RR 0.58, 95% CI 0.36–0.94; P=0.03) and shorter hospital length stay (7 days vs 12 days, p=0.02). However, echocardiographic postoperative aortic valve gradients were lower in sAVR group than in tVIV (RR 1.83, 95% CI 0.75–2.91, p<0.001).
30-day and long-term mortality
Conclusion
This meta-analysis suggests that patients with aortic degenerated bioprosthesis treated with tVIV have similar 30-day and long-term mortality with lower need of permanent pacemaker and length stay than sAVR. Thus tVIV is a valid alternative to standard surgical treatment.

Abstract
Abstract
Background
Aortic stenosis (AS) results in high pressure afterload causing detrimental effect especially on the left chambers. Structural and functional changes of the left ventricle (LV) usually corresponds to concomitant remodelling of the left atrium (LA). However, how this pressure afterload specifically affects LA function and whether the study of LA function could help in stratifying patients with different degree of AS it is not known.
Purpose
We aim to evaluate the differences in LA and LV function according different degree of AS by standard and speckle tracking echocardiographic.
Methods
From January 2016 to May 2018 we recruited 135 patients referring to our echo-lab with diagnosis of AS (mean age 79.5±4.4; 60/55% female). We divided this population according to AS severity in patients with moderate AS, severe asymptomatic and severe symptomatic AS and matched with 35 control group with no aortic stenosis (n=45, mean age: 77.6±4.5). All patients underwent standard and 2-dimensional speckle tracking echocardiography computing global longitudinal strain (GLS) of LV and peak atrial strain of LA (PALS).
Results
In all patients PALS was a good predictor of E/e' ratio after correction for LV EF and age (p<0.001, β: −0.48). LVEF and GLS progressively decreased together with worsening of AS degree, as well as parameters of geometry and function of LA (Table1). By excluding patients with LV dysfunction the reduction gradient of parameters of LA geometry and function was still present. However, when severe symptomatic with asymptomatic severe AS are compared, no difference in E/e' ratio was found while both GLS and PALS were significantly reduced (both p<0.0001).
Variables Overall population (180) Control (45) Moderate AS (45) Severe asympt AS (45) Severe sympt. AS (45) p LVEF 65.0±11.1 67.7±5.6 69.4±8.5 66.1±10.7 59.5±13.5 0.0001 GLS −20.4±4.1 −23.1±2.4 −21.5±2.9 −21.4±3.2 −17.1±4.3 0.0001 LA vol index 41.6±21.5 28.2±10.4 40.1±19.7 39.8±16.7 52.3±24.9 0.0001 LA strain 23.6±10.9 30.8±10.3 27.8±9.2 24.4±9.7 15.2±7.1 0.0001 LA reservoir 46.4±15.9 51.9±11.5 53.0±15.0 48.3±14.1 37.2±16.1 0.0001 Ee' ratio 14.8±7.0 9.6±2.7 13.7±6.3 15.4±6.2 19.3±7.2 0.0001
Conclusions
LA function seems to progressively decrease according to the degree of AS, independently from LV function. Significant difference was found between parameters of LA remodelling and dysfunction between symptomatic and asymptomatic AS patients. The assessment of LA function by strain may help stratify the patients with AS, identifying those who need intensive medical/surgical treatment.

Abstract
Prototyping hyperspectral imaging devices in current biomedical optics research requires taking into consideration various issues regarding optics, imaging, and instrumentation. In summary, an ideal imaging system should only be limited by exposure time, but there will be technological limitations (e.g., actuator delay and backlash, network delays, or embedded CPU speed) that should be considered, modeled, and optimized. This can be achieved by constructing a multiparametric model for the imaging system in question. The article describes a rotating-mirror scanning hyperspectral imaging device, its multiparametric model, as well as design and calibration protocols used to achieve its optimal performance. The main objective of the manuscript is to describe the device and review this imaging modality, while showcasing technical caveats, models and benchmarks, in an attempt to simplify and standardize specifications, as well as to incentivize prototyping similar future designs.

Abstract
Bioactive PEO (Plasma Electrolytic Oxidation) coatings were generated on Grade I commercially pure titanium for dentistry applications using a Ca/P-based electrolyte with added Si, Mg, Zn or F species. Surface characteristics, chemical composition and ion liberation of the coatings were characterized using SEM/EDS, X-ray diffraction, optical profilometry, contact angle and ICP-OES. Corrosion resistance (OCP and DC polarization) was evaluated in SBF. Osteoblastogenesis and osteoclastogenesis processes on PEO-coated Ti and non-coated Ti controls were assessed after 7 days and 5 days of cell culture, respectively. Monolayer formation and metabolic activity were evaluated for the MC3T3 preosteoblastic cell line. All PEO coatings favoured differentiation processes over proliferation and presented three times greater quantity of secreted collagen than non-coated Ti control. All coating enabled osteoclast differentiation, with differences in number and size of the osteoclasts between the materials.

Abstract
Early detection and diagnosis is a must in secondary prevention of melanoma and other cancerous lesions of the skin. In this work, we present an online, reservoir-based, non-parametric estimation and classification model that allows for this functionality on pigmented lesions, such that detection thresholding can be tuned to maximize accuracy and/or minimize overall false negative rates. This system has been tested in a dataset consisting of 116 patients and a total of 124 hyperspectral images of nevi, raised nevi and melanomas, detecting up to 100% of the suspicious lesions at the expense of some false positives.

Abstract
SummaryThe multimeric and subunit patterns of plasma von Willebrand factor (vWF) were analyzed in eight patients with myeloproliferative syndrome (MS) in order to investigate the possible existence of heterogeneity in the “in vivo” proteolytic cleavage of the protein, previously observed in this entity. Six patients lacked large vWF multimers, five of them having normal bleeding times (BT) and clinically documented episodes of thrombotic origin, whereas one patient had long BT and bleeding symptoms. Seven patients showed a relative increase in the 176 kDa subunit fragment while the 189 kDa polypeptide was increased in only one. In addition, another patient (and prior to any therapy) showed the presence of a new fragment of approximately 95 kDa which disappeared after Busulfan therapy. The collection of blood from these patients with proteinase inhibitors did not correct the abnormalities.The infusion of DDAVP to two patients with abnormal vWF was accompanied by: the appearance of larger vWF multimers which disappeared rapidly from plasma; an increase in the relative proportion of the satellite bands of each multimer and a further increase of the 176 kDa fragment. These data point to some heterogeneity in the vWF abnormality present in MS which may be related in part to a variable degree of proteolysis of vWF occurring “in vivo” rather than “in vitro”, and which may be associated to either a thrombotic or a bleeding diathesis. They also suggest that despite the presence of abnormal, already proteolyzed vWF, DDAVP-enhanced proteolysis occurs in MS to a similar extent to what is described in normal individuals.

Abstract
In Breast Conserving Therapy, surgeons measure the thickness of healthy tissue surrounding an excised tumor (surgical margin) via post-operative histological or visual assessment tests that, for lack of enough standardization and reliability, have recurrence rates in the order of 33%. Spectroscopic interrogation of these margins is possible during surgery, but algorithms are needed for parametric or dimension reduction processing. One methodology for tumor discrimination based on dimensionality reduction and nonparametric estimation-in particular, Directional Kernel Density Estimation-is proposed and tested on spectral image data from breast samples. Once a hyperspectral image of the tumor has been captured, a surgeon assists by establishing Regions of Interest where tissues are qualitatively differentiable. After proper normalization, Directional KDE is used to estimate the likelihood of every pixel in the image belonging to each specified tissue class. This information is enough to yield, in almost real time and with 98% accuracy, results that coincide with those provided by histological H&E validation performed after the surgery.

Abstract
Ecological limits to phenotypic plasticity (PP), induced by simultaneous biotic and abiotic factors, can prevent organisms from exhibiting optimal plasticity, and in turn lead to decreased fitness. Herbivory is an important biotic stressor and may limit plant functional responses to challenging environmental conditions such as shading. In this study we investigated whether plant functional responses and PP to shade are constrained by herbivory, and whether such constraints are due to direct effects based on resource limitation by considering ontogeny. We used as a model system the relict tree Prunus lusitanica and implemented an indoor experiment to quantify the response of saplings of different ages to shade and herbivory. We measured five functional traits and quantitatively calculated PP. Results showed that herbivory did not constrain functional responses or PP to shade except for shoot:root ratio (SR), which, despite showing a high PP in damaged saplings, decreased under shade instead of increasing. Damaged saplings of older age did not exhibit reduced constraints on functional responses to shade and generally presented a lower PP than damaged saplings of younger age. Our findings suggest that herbivory-mediated constraints on plant plasticity to shade may not be as widespread as previously thought. Nonetheless, the negative effect of herbivory on SR plastic expression to shade could be detrimental for plant fitness. Finally, our results suggest a secondary role of direct effects (resource-based) on P. lusitanica plasticity limitation. Further studies should quantify plant resources in order to gain a better understanding of this seldom-explored subject.

Abstract
Uranium-lead geochronology in detrital zircons and provenance analyses in eight boreholes and two surface stratigraphic sections in the northern Andes provide insight into the time of closure of the Central American Seaway. The timing of this closure has been correlated with Plio-Pleistocene global oceanographic, atmospheric, and biotic events. We found that a uniquely Panamanian Eocene detrital zircon fingerprint is pronounced in middle Miocene fluvial and shallow marine strata cropping out in the northern Andes but is absent in underlying lower Miocene and Oligocene strata. We contend that this fingerprint demonstrates a fluvial connection, and therefore the absence of an intervening seaway, between the Panama arc and South America in middle Miocene times; the Central American Seaway had vanished by that time.

Abstract
Introduction: Over the years, several different implant systems have been introduced, and the indications for implant rehabilitation have gradually been extended 2. Although an high success rates have consistently been reported for many implant systems, complications leading to loss of osseointegration still occurs 3. Thus, oral hygiene and maintenance are imperative, because implants, as well as teeth, are susceptible to accumulation of bacterial plaque and calculus formation. The aim of the present study was to evaluate and compare the in vivo cleaning efficacy of the three systems (air powder, curette, laser) comparing at the same time the alterations of the titanium abutment surface in terms of roughness. Methods: Forthy-two patients (25 males and 17 females) were included in the study. The 42 healing abutments were treated by the same clinician (UC). Results and conclusions: The rate of debris removal by the air powder was higher than that for the laser and than that for the curettes. The SEM analysis showed that the air powder system did not induce significant differences of the abutment if compared to the curettes as well as to the laser.

Abstract
Background: Lateral Periodontal cyst (LPC) is an uncommon development odontogenic cyst. Most papers are single case reports or series. Methods: We present a case of LPC occurred in a patient which symptoms and signs could mislead the diagnosis. A review of the literature is reported, emphasizing the clinical, radiographic and histopathological features of LPC. Results: A 28-years old female patient presented reporting pain and swelling at the lingual site of the #31.Spot lingual probing depth was 9 mm; sulcus bleeding and suppuration were found at probing. Radiographically well-defined radiolucency appeared in periodontal foramen area. The patient was treated with non-surgical and surgical therapy. Conclusions: LPC is an infrequent cystic lesion that occurs on lateral root vital tooth. In this case, the cyst mimicked a periodontal lesion. The surgical LPC excision solved the symptoms reported by the patient and improved periodontal parameters of the dental element. After 18 months since surgical treatment there aren't signs or symptoms of recurrence.

Abstract
The aim of study was to determine and compare serum concentrations of interleukin 1 beta (IL-1β), interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-α) in patients with oral ameloblastoma and healthy controls. Sixteen patients with ameloblastoma and 16 healthy controls were enrolled in this study. Cytokine concentrations were measured by chemiluminescent enzyme linked immunoassay. Serum concentrations of IL-1β were below level of detection in all but four participants. No significant differences between the groups were observed in serum concentrations of IL-6. Serum TNF-α was significantly higher in control subjects than in ameloblastoma patients. Patients diagnosed with ameloblastoma have relatively normal levels of inflammatory cytokines in their blood and thus cannot be used as indicators of disease severity or for monitoring the treatment outcomes.

Abstract
Quercetin (3,3',4',5,7-pentahydroxyflavone) is the major bioflavonoid in the human diet and belongs to an extensive class of polyphenolic flavonoid compounds almost ubiquitous in plants and plant food sources. The estimated average daily dietary intake of quercetin by an individual in the United States is 25 mg. In recent years, research about quercetin has evolved from animal studies to in vitro and in vivo studies and to human clinical studies and trials in order to establish its real properties and effects. In oral medicine, quercetin has been extensively studied, as a real increase in major diseases like cancers, periodontal disease, oral lesions, tooth decay and infections have been reported worldwide by health providers.It has been thus established that quercetin exhibits beneficial effects on oral health with its broad pharmacological properties, as preventive and therapeutic agent in dental caries with anti-inflammatory effect against oral pathogens, as well as an antioxidant and anti-cancer agent .The aim of the review is to present evidence-based aspect of treatment with quercetin in order to validate its tremendous role in dentistry and maxillofacial surgery.

Abstract
The present case report describes the case of a 15-year-old female who was referred with a radiolucent lesion between her mandibular right molars. The original radiographic image suggested the presence of an odontogenic cyst. The surgical enucleation and the following osteotomy of the residual cavity was performed by using the piezoelectric technology. The histological analysis confirmed that the lesion was an odontogenic keratocyst with no evidence of epithelial invasion in the connective tissue wall. The patient refused any further surgical treatment. In consideration of the pathological result - no presence of invasive epithelial cells in the connective tissue wall of the cyst- the patient was suggested a "follow-up and wait-and-see policy", with more extensive surgical treatment to be given only in case of a recurrence. The patient was followed up clinically and radiographically at 6 months intervals for 5 years.

Abstract
Bulimia nervosa is an eating disorder characterized by consuming a large amount of food in a short amount of time followed by an attempt to rid oneself of the food consumed (purging), typically by vomiting, taking a laxative, diuretic, or stimulant, and/or excessive exercise, because of an extensive concern for body weight. The frequent contact between teeth and gastric acid, in particular, may cause: severe dental erosion, perimolysis, or the erosion of tooth enamel and swollen salivary glands. Constant vomiting can lead to gastroesophageal reflux. The aim of this article is to report two cases of patients with severe dental demineralization associated with bulimia nervosa during orthodontic treatment. Diagnosis and prevention aspects are highlighted and discussed.

Abstract
Background: The aim of present study was to clinically assess and compare a sonic toothbrush versus a rotating oscillating power toothbrush on plaque removal and gingival health in reducing plaque and bleeding on probing. Methods: Patients were selected according to specific inclusion and exclusion criteria and they were enrolled in test group or control group using Random Allocation Software. Visual score plaque index (PI) was recorded by the same blind operator using a plaque revelator and bleeding on probing (BoP) index was recorded using a periodontal probe at baseline, 15th day and 30th day. Results: The group of patients who used sonic toothbrush showed a greater reduction of PI and BoP comparing with patients who used rotating-oscillating power toothbrush. Conclusions: Although this pilot study has several limitations, it seems to indicate that sonic toothbrushes are capable of removing plaque and reducing bleeding on probing better than electric toothbrushes.

Abstract
Objective: Trying to limit the use of antimicrobial drugs in periodontitis is a general trend. Thus, the aim of the present study was to assess the efficacy of daily water irrigation in comparison with subgingival minocycline in periodontal maintenance, in subjects with moderate to severe periodontitis. This was done by evaluating probing pocket depth (the primary outcome), other clinical parameters such as clinical attachment level, plaque index and bleeding on probing, and bacterial flora changes inside periodontal pockets. Materials and Methods: In this single-center, parallel, single blind, randomized clinical study, thirty subjects (12 men, mean age 56 ± 2.2 years) with moderate to severe periodontitis were randomized 1:1 into a minocycline-treated group (M-group, n=15) and a water-treated group (W-group, n=15). Clinical and microbiological parameters were measured at baseline. Scaling and root planing were carried out on all subjects, then to M-group patients minocycline was administered inside the pockets. W-group subjects had instead to daily apply oral irrigation with water. Clinical and microbiological measurements were repeated after 30 days. Results: Both water irrigation and minocycline treatment led to a significant reduction of all the clinical parameters tested at t=30 days with respect to baseline. Moreover, both procedures appeared to be able to maintain a low bacterial load inside periodontal pockets, for most of the microorganisms tested. No statistically significant differences were observed between M-group and W-group at t=30 days, concerning both clinical and microbiological parameters. However, further studies are needed to assess the long-term effect. Conclusion: Daily oral irrigation with water showed comparable efficacy to a single administration of minocycline in periodontal maintenance subjects.

Abstract
Bioactive PEO coating on titanium with high Ca/P ratio was fabricated and characterized with respect to its morphology, composition and microstructure. Long-term electrochemical stability of the coating and Ti(4+) ion release was evaluated in artificial saliva. Influence of the lactic acid and fluoride ions on corrosion protection mechanism of the coated titanium was assessed using AC and DC electrochemical tests. The PEO-treated titanium maintained high passivity in the broad range of potentials up to 2.5 V (Ag/AgCl) for up to 8 weeks of immersion in unmodified saliva and exhibited Ti(4+) ion release <0.002 µg cm(-2) days(-1). The high corrosion resistance of the coating is determined by diffusion of reacting species through the coating and resistance of the inner dense part of the coating adjacent to the substrate. Acidification of saliva in the absence of fluoride ions does not affect the surface passivity, but the presence of 0.1 % of fluoride ions at pH ≤4.0 causes loss of adhesion of the coating due to inwards migration of fluoride ions and their adsorption at the substrate/coating interface in the presence of polarisation.
