Abstract
Amygdala atypical volume development and functional connectivity (FC) at small gestational ages (GA) have been found across childhood. This adult-oriented study assesses whether altered amygdala structure and function is present following low-risk preterm birth. T1-weighted and resting-state functional MRI images of 33 low-risk preterm (30-36 weeks' GA) and 29 full-term (37-42 weeks' GA) young adults of both sexes, aged between 20 and 32 years old, were analyzed using FreeSurfer (v6.0.0) and Coon Toolbox (v21.a). The social-emotional assessment included Happé's Strange Stories Test, the Moral Judgment Test, Delay-Discounting Test, Adult Self Report, and Emotion Regulation Questionnaire. No differences were found in social-emotional outcomes or amygdala volumes between the groups. Low-risk preterm young adults showed increased FC between the left amygdala, right amygdala and medial frontal cortex (MedFC) (F = 9.89, p-FWE = 0.009) at cluster level compared to their full-term peers. However, significant results at connection level were not observed between left and right amygdala. Lastly, increased FC at cluster level between the right amygdala and MedFC, and left amygdala and MedFC, was related to better social-emotional outcomes only in low-risk preterm young adults (F = 6.60, p-FWE = 0.036) at cluster level. At connection level, in contrast, only right amygdala-MedFC increased FC was significantly associated with better social-emotional outcomes. This study reveals that low-risk prematurity does not have an effect on social-emotional outcomes or structural amygdala volumes during young adulthood. However, individuals who were considered to be at a lower risk of exhibiting neurodevelopmental alterations following preterm birth demonstrated increased FC between the left and right amygdala and MedFC.

Abstract
INTRODUCTION The UD Interference Test measures processing speed and attention, and is based on the concept of interference of the Stroop Color and Word Test. The main purpose of the study is to provide an alternative version of the Stroop Color and Word Test that overcomes some of the limitations of previous versions in assessing individuals with daltonism or age-related reading difficulties, and to obtain normative and standardised data for the Spanish population. METHODS This study is part of the Normacog project. We evaluated 905 individuals (age range, 18-93 years) to analyse the test's reliability and concurrent and construct validity. We evaluated the effect of age, sex, and level of education on UD Interference Test performance and calculated percentiles and age- and education-adjusted scaled scores. RESULTS The test has good reliability (α = 0.875) and concurrent (r = 0.443-0.725; P < .001) and construct validity (r = 0.472-0.737; P < .001). We observed age and educational level to have a significant effect on UD Interference Test scores, explaining 12% to 40% of variance. Sex only had a significant effect on the resistance to interference index. CONCLUSIONS We present an alternative version of the Stroop Color and Word Test with some advantages over previous versions. We provide standardised and normalised data for the Spanish population to correct the test according to the subject's age and level of education.

Abstract
AIM Compare bone formation capacity in vivo of two types of biomaterials designed as bone substitutes with respect to iliac crest autograft, one based on carbonate hydroxyapatites and the other one on bioactive mesoporous glass. MATERIALS AND METHODS Experimental study consisting on 14 adult female New Zeland rabbits where a critical defect was made in the rabbit radius bone. The sample was divided into four groups: defect without material, with iliac crest autograft, with carbonatehydroxyapatite support, and with bioactive mesoporous glass support. Serial X-ray studies were carried out at 2, 4, 6 and 12 weeks and a microCT study at euthanasia at 6 and 12 weeks. RESULTS In the X-ray study, autograft group showed the highest bone formation scores. Both groups of biomaterials presented bone formation similar and greater than the defect without material, but always less than in the autograft group. The results of the microCT study showed the largest bone volume in the study area in the autograft group. The groups with bone substitutes presented greater bone volume than the group without material but always less than in the autograft group. CONCLUSION Both supports seem to promote bone formation but are not capable of reproducing the characteristics of autograft. Due to their different macroscopic characteristics, each one could be suitable for a different type of defect.

Abstract
BACKGROUND Alemtuzumab is a highly effective treatment for relapsing remitting multiple sclerosis (RRMS), but in recent years safety-related concerns had emerged due to description of novel serious side effects not registered in CARE-MS I and CARE-MS II phase 3 studies, nor in TOPAZ extension study. Data about alemtuzumab use in real clinical practice are limited and based mainly on retrospective studies with small sample sizes. Therefore, more information about effectiveness and safety of alemtuzumab in this context is needed. METHODS A multicenter observational prospective study to investigate effectivity and safety of alemtuzumab in a real-world setting was performed. Primary endpoints were the change in annualized relapse rate (ARR), and in disability measured by EDSS score. Secondary endpoints were the cumulative probability of confirmed 6-month disability improvement and worsening. Disability worsening and disability improvement were considered when the EDSS score was increased or decreased, respectively, in 1 point if baseline EDSS score was <5.0, or in 0.5 point if baseline EDSS score was ≥5.5, confirmed over 6 months. Other secondary endpoint was the proportion of patients who achieved NEDA-3 status (absence of clinical relapses, disability EDSS progression, and MRI disease activity as depicted by new/enlarging T2 lesions or Gadolinium enhancing T1 lesions). Adverse events also were recorded. RESULTS A total of 195 RRMS patients (70% female) who started alemtuzumab treatment were included. Mean of follow-up was 2.38 years. Alemtuzumab significantly reduced the annualized relapse rate from baseline with risk reductions of 86%, 83.5%, and 84%, at 12, 24, and 36 months of follow-up respectively (Friedman test, p-value < 0.05 for all comparisons). Alemtuzumab also significantly reduced EDSS score over one and two years after starting alemtuzumab treatment (Friedman test, p-value<0.001 for both comparisons). A high proportion of patients presented confirmed 6-month stability or disability improvement (92%, 82%, and 79%, over 1, 2 and 3 years of follow-up respectively). The proportion of patients who retained NEDA-3 status at 12, 24 and 36 months were 61%, 49%, and 42%, respectively. Baseline characteristics associated with a lower probability of achieving NEDA-3 were younger age, sex female, high ARR, elevated number of previous treatments, and switch from a second line therapy. Infusion related reactions were the most frequent adverse event observed. The most common infections were urinary tract infections (50%), and upper respiratory tract infections (19%) over the 3 years of follow- up. Secondary thyroid autoimmunity was developed in 18.5% of patients. CONCLUSION Alemtuzumab has demonstrated in real clinical practice high effectiveness in controlling multiple sclerosis activity, and no unexpected adverse events were observed.

Abstract
The purpose of this study was to identify changes in neuromuscular performance variables evaluated through the countermovement jump test before and after (0 hours, after session and 24h post) of a simulated futsal protocol in young university female athletes. Fourteen eumenorrheic, healthy and experienced female futsal players were randomly assigned to an intervention group n = 7) or a control group (n = 7). Both groups performed three countermovement jumps before and after the protocol using an inertial system device. The intervention group completed a short-term functional agility and fatigue protocol that simulated the characteristics of futsal, while the control group did not perform any exercise. The results showed a reduction in peak flight time (p = 0.049; d = 0.586), peak concentric work (p = 0.03; d = 1.819) and peak maximum force (p = 0.02; d = 0.782) comparing experimental and control group. No changes in other variables examined were noted between conditions (p > 0.05). These findings indicate that the changes in neuromuscular performance variables, evaluated through a simulated protocol, are established as determinants in the definition of peripheral fatigue in futsal practitioners until 24 h after a demanding intervention.

Abstract
BACKGROUND The impact of the pediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) in low- and middle-income countries remains poorly understood. Our aim was to understand the characteristics and outcomes of PIMS-TS in Argentina. METHODS This observational, prospective, and retrospective multicenter study enrolled patients younger than 18 years-old manifesting PIMS-TS, Kawasaki disease (KD) or Kawasaki shock syndrome (KSS) between March 2020 and May 2021. Patients were followed-up until hospital discharge or death (one case). The primary outcome was pediatric intensive care unit (PICU) admission. Multiple logistic regression was used to identify variables predicting PICU admission. RESULTS Eighty-one percent, 82%, and 14% of the 176 enrolled patients fulfilled the suspect case criteria for PIMS-TS, KD, and KSS, respectively. Temporal association with SARS-CoV-2 was confirmed in 85% of the patients and 38% were admitted to the PICU. The more common clinical manifestations were fever, abdominal pain, rash, and conjunctival injection. Lymphopenia was more common among PICU-admitted patients (87% vs. 51%, p < 0.0001), who also showed a lower platelet count and higher plasmatic levels of inflammatory and cardiac markers. Mitral valve insufficiency, left ventricular wall motion alterations, pericardial effusion, and coronary artery alterations were observed in 30%, 30%, 19.8%, and 18.6% of the patients, respectively. Days to initiation of treatment, rash, lymphopenia, and low platelet count were significant independent contributions to PICU admission. CONCLUSION Rates of severe outcomes of PIMS-TS in the present study agreed with those observed in high-income countries. Together with other published studies, this work helps clinicians to better understand this novel clinical entity.

Abstract
INTRODUCTION The UD Interference Test measures processing speed and attention, and is based on the concept of interference of the Stroop Test. The main purpose of the study is to provide an alternative version of the Stroop Test that overcomes some of the limitations of previous versions in assessing individuals with daltonism or age-related reading difficulties, and to obtain normative and standardised data for the Spanish population. METHODS This study is part of the Normacog project. We evaluated 905 individuals (age range, 18-93 years) to analyse the test's reliability and concurrent and construct validity. We evaluated the effect of age, sex, and level of education on UD Interference Test performance and calculated percentiles and age- and education-adjusted scaled scores. RESULTS The test has good reliability (α = 0.875) and concurrent (r = 0.443-0.725; p < .001) and construct validity (r = 0.472-0.737; p < .001). We observed age and educational level to have a significant effect on UD Interference Test scores, explaining 12-40% of variance. Sex only had a significant effect on the resistance to interference index. CONCLUSIONS We present an alternative version of the Stroop Color and Word Test with some advantages over previous versions. We provide standardised and normalised data for the Spanish population to correct the test according to the subject's age and level of education.

Abstract
INTRODUCTION The brief visuospatial memory test-revised (BVMT-R) assesses visuospatial learning and memory in adults. It has equivalent forms that allow reassessing patients. AIM To obtain normative and standardized data for the BVMT-R taking into account the sociodemographic characteristics of the Spanish population. SUBJECTS AND METHODS The present study is part of the Normacog Project. Nine hundred three participants (18 to 93 years old) were assessed using the BVMT-R (form 1). The effect of age, level of education and gender was analyzed on the BVMT-R, and percentiles and scalar scores adjusted by age and level of education were created. RESULTS A significant effect of age and educational level on the analyzed variables was observed (trial 1; total recall; trial 4; discrimination index), explaining from 12% to 40% of the variance. The older and less educated participants obtained lower performance in all the analyzed variables of the BVMT-R. Gender had not a significant effect in the analyzed variables. CONCLUSION The study provides standardized and normalized data for the BVMT-R taking into account the Spanish sociodemographic characteristics. The results confirm the in?uence of age and level of education in the performance of the test, so normative data are provided to correct the BVMT-R taking into account these characteristics.

Abstract
INTRODUCTION The Hopkins Verbal Learning Test-revised (HVLT-R) was originally created with the objective of providing a short verbal memory and learning test with six alternative forms that allow the re-administration. AIM To obtain normative and standardized data for the HVLT-R taking into account the sociodemographic characteristics of the current Spanish population. SUBJECTS AND METHODS The study is part of the Normacog Project. Seven hundred participants (18 to 90 years old) were assessed. The effect of age, level of education and gender on the performance of HVLT-R were analyzed, and percentiles and scalar scores adjusted by age and level of education were created. RESULTS A significant effect of age and educational level on the analyzed variables of the test was observed, explaining from 15% to 29% of the variance (trial 1, total recall, trial 4, discrimination index). As expected, the older and less educated obtained lower performance in all the analyzed variables of the HVLT-R. However, sex only had a significant effect on the variables trial 1, total recall and discrimination index. CONCLUSION This study provides standardized and normalized data for the HVLT-R for the Spanish population, offering current norms to clinicians and researchers. The results confirm the influence of age and level of education on all the indicators of the test, so normative data are provided to correct the HVLT-R taking into account these characteristics.

Abstract
Quantifying the distribution of animals and identifying underlying characteristics that define suitable habitat are essential for effective conservation of free-ranging species. Prioritizing areas for conservation is important in managing a geographic extent that has a high level of disturbance and limited conservation resources. We examined the potential use of a species distribution model ensemble for multi-species conservation in marine habitats. Using satellite telemetry locations during foraging as input data, and ensemble ecological niche models, we predicted foraging areas for 2 nesting marine turtle species within the Gulf of Mexico (GoM): Kemp’s ridley Lepidochelys kempii (n = 63) and loggerhead Caretta caretta (n = 63). We considered 7 geophysical, biological, and climatic variables and compared contributing factors for each species’ foraging habitat selection. For both species, predicted suitable foraging habitats encompassed large areas along the GoM coast, but only intersected with each other in relatively small areas. Highly parameterized models resulted in overall greater fits, suggesting that multiple factors influence habitat selection by these species. Model validation results were mixed: cross-validation resulted in high prediction accuracy for both species, but an evaluation against independent data resulted in a low omission rate (5%) for Kemp’s ridleys and a high omission rate (72%) for loggerheads. The relatively small intersection of model-predicted foraging areas for these 2 species within the study area may indicate possible niche differentiations. The high omission rate for loggerheads indicates our samples likely underrepresent the population and illustrates the challenges in predicting suitable foraging extents for species that make dynamic movements and have greater individual variability.

Abstract
Abstract
Background
Muscle strength is considered as a health indicator and an independent predictor of future disease. For this reason, the evaluation of this component in the young population is recognised as a fundamental strategy for the prevention of non-communicable diseases. Field tests are the techniques most commonly used to evaluate muscle strength. However, an alternative method that could be applied in epidemiological studies is self-report questionnaires. The aim of this research was to evaluate the ability of a self-report questionnaire to correctly rank the levels of muscle strength in college students.
Methods
A cross-sectional study was developed in 135 students from the Areandina University in Bogota, Colombia. For the evaluation of muscle strength, two tests were applied. The first was the application of the handgrip protocol using an adjustable handle Digital Grip Strength Dynamometer. The second was the application of protocols to a maximum repetition in 6 different exercises. For the assessment of self-perceived strength, the third question of the International Scale Fitness Questionnaire (IFIS) was applied. The IFIS response options are presented on a Likert scale with five possible answers: “very poor”, “poor”, “average”, “good” or “very good”. An analysis of variance (ANOVA) was applied to evaluate the ability of the IFIS questionnaire to rank muscle strength levels correctly.
Results
Overall, 70.3% of the participants were men, and 29.7% were women. The results of the field tests and the self-perception of muscle strength were significantly higher in the male group than in the female group (P < 0.001). Students who reported having good or very good muscle strength in the questionnaire had a better result in the field tests compared to those who reported average, poor or very poor muscle strength levels (P < 0.005).
Conclusions
The IFIS questionnaire was able to rank real muscle strength in university students correctly.
Key messages
The IFIS questionnaire is a valid alternative to detect students with a potential risk of chronic non-communicable diseases. The epidemiology surveillance systems in Colombia should include the application of self-report questionnaires that evaluate potential risk factors.

Abstract
Abstract
Background
Experimental studies have determined that higher strength values are associated with more efficient cognitive function and better academic performance. In spite of this, the universities in Colombia are decreasing the time available for physical activity in favour of increasing the time devoted to theoretical subjects. This is one of the reasons why in Colombia, only 18% of young people complied with the world recommendations of physical activity. To examine this problem, the objective of this research was to establish the relationship between strength and academic performance in university students.
Methods
A cross-sectional study was developed in 135 (21.8 ± 4.5 yr; 78.69 ± 9.1kg) students of the fifth semester of the Areandina University in Bogota, Colombia. Each participant developed incremental protocols to determine the maximum weight that he or she could move in six different exercises: squat in smith machine, leg press, leg extension, bench press, pull down and military press. The average of the results of these tests was taken as the value of maximum strength. To determine academic performance, the average of the scores accumulated in the five semesters of their university studies was evaluated. Pearson correlation coefficient was used to find the linear relationship between strength and academic performance.
Results
Overall, 70.3 % of the participants were men and 29.7% were women. The results of the maximum strength tests were significantly higher in the male group than in the female group (P < 0.05). Academic performance was similar in both genders (P > 0.05). A positive correlation was established between maximum strength and academic performance. (r = 0.64 P < 0.05).
Conclusions
The conclusion of this research was that there is a significant relationship between strength and academic performance. These results are fundamental to justify the inclusion of spaces for the promotion of physical activity in public and private universities.
Key messages
Universities are institutions that only focus on academic training and generate contexts in which sedentary behaviours are promoted. Sedentary lifestyles are a public health problem in Colombia.

Abstract
There is an urgent need of biosynthetic bone grafts with enhanced osteogenic capacity. In this study, we describe the design of hierarchical meso-macroporous 3D-scaffolds based on mesoporous bioactive glasses (MBGs), enriched with the peptide osteostatin and Zn2+ ions, and their osteogenic effect on human mesenchymal stem cells (hMSCs) as a preclinical strategy in bone regeneration. The MBG compositions investigated were 80%SiO2-15%CaO-5%P2O5 (in mol-%) Blank (BL), and two analogous glasses containing 4% ZnO (4ZN) and 5% ZnO (5ZN). By using additive fabrication techniques, scaffolds exhibiting hierarchical porosity: mesopores (around 4 nm), macropores (1-600 μm) and big channels (∼1000 μm), were prepared. These MBG scaffolds with or without osteostatin were evaluated in hMCSs cultures. Zinc promoted hMSCs colonization (both the surface and inside) of MBG scaffolds. Moreover, Zn2+ ions and osteostatin together, but not independently, in the scaffolds were found to induce the osteoblast differentiation genes runt related transcription factor-2 (RUNX2) and alkaline phosphatase (ALP) in hMSCs after 7 d of culture in the absence of an osteogenic differentiation-promoting medium. These results add credence to the combined use of zinc and osteostatin as an effective strategy for bone regeneration applications. STATEMENT OF SIGNIFICANCE: Mesoporous bioactive glasses (MBGs) are bioceramics whose unique properties make them excellent materials for bone tissue engineering. Physico-chemical characterization of MBGs as scaffolds made by rapid prototyping, doped with zinc (potential osteogenic, angiogenic and bactericidal ion) and loaded with osteostatin (osteogenic peptide) are described. These Zn-MBGs scaffolds showed 3D hierarchical meso-macroporous structure that enables to host and release osteostatin. When decorated with human mesenchymal stem cells (hMSCs), MBGs scaffoldsenriched with both zinc and osteostatin exhibited a synergistic effect to enhance hMSCs growth, and also hMSCs osteogenic differentiationwithout addition of other osteoblastic differentiation factors to the culture medium. This novel strategy has a great potential for use in bone tissue engineering.

Abstract
Total lipids and docosahexaenoic acid (DHA) production by a Chilean isolated thraustochytrid were evaluated under different growth conditions in shake flasks. The analyzed strain was identified as Thraustochytrium striatum according to an 18S rRNA gene sequence analysis. The strain (T. striatum AL16) showed negligible growth in media prepared with artificial seawater at concentrations lower than 50% v/v and pH lower than 5. Maltose and starch were better carbon sources for growth than glucose. DHA content of the biomass grown with maltose (60 g L-1) was doubled by increasing the agitation rate from 150 to 250 rpm. The DHA (0.8-6%) and eicosapentaenoic acid (0.2-21%) content in the total lipids varied depending on culture conditions and culture age. Lipid and DHA concentration increased (up to 5 g L-1 and 66 mg L-1, respectively) by regularly feeding the culture with a concentrated starch solution. Carotenoid accumulation was detected in cells grown with maltose or starch. Contrasting conditions of starch and glucose cultures were selected for comparative proteomics. Total protein extracts were separated by two-dimensional gel electrophoresis; 25 spots were identified using ESI-MS/MS. A protein database (143,006 entries) for proteomic interrogation was generated using de novo assembling of Thraustochytrium sp. LLF1b - MMETSP0199_2 transcriptome; 18 proteins differentially expressed were identified. Three ATP synthases were differentially accumulated in cultures with glucose, whereas malate dehydrogenase was more abundant in cells cultured with starch.

Abstract
Whereas the efficacy of cognitive rehabilitation in schizophrenia is widely known, studies examining mechanisms for functional improvement are still scarce. The aim of the study was to examine the mediational mechanisms through which cognitive rehabilitation improves functioning in schizophrenia. One hundred and eleven schizophrenia patients were randomly assigned to either a 4-month cognitive rehabilitation group or an active control group. Patients underwent a neurocognitive battery (including processing speed, verbal memory, working memory and executive functioning) and social cognition assessment (emotion perception, theory of mind and social perception). Functioning was assessed by the combined use of a performance-based instrument, the UCSD Performance-based Skills Assessment (UPSA) and an observer-rated instrument, the Global Assessment of Functioning (GAF). The trial was registered in clinicaltrials.gov (NCT02796417). Multiple mediational analyses revealed that the effect of cognitive rehabilitation on functional improvement was partially mediated by changes in processing speed and verbal memory, but not by the domains of social cognition and negative symptoms. More specifically, verbal memory partially mediated the treatment's effect on performance-based functioning (UPSA), whereas processing speed acted as a partial mediator for observer-rated functioning (GAF). The effect of rehabilitation on functioning did not take place through all the domains that showed significant improvement. Verbal memory and processing speed emerged as the most crucial factors. However, these complex interactions need further research.

Abstract
SummaryThe Biomechanically founded individualised osteoporosis Assessment and treatment (BioAsset) consortium pursues experimental and clinical studies in the context of skeletal effects of bisphosphonate treatment. Here, first results using newly developed diagnostic methods in a set of vertebral bone specimen obtained from donors with documented bisphosphonate history ranging from 0 to more than 5 years of treatment are presented. A new thoracolumbar quantitative computed tomography (QCT) protocol covering T6 to L4 plus high-resolution QCT (HRQCT) assessment of T12 were compared with high-resolution peripheral QCT (HRpQCT) and micro-CT scans of excised specimens serving as gold standard techniques. Finite element (FE) modelling was performed. Material, ultrastructural, and micromechanical properties were tested on a set of single trabeculae obtained from the donor specimens. A newly developed quantitative ultrasound (QUS) device for measuring the anisotropy of cortical material properties at the tibia was designed and built. The thoracolumbar QCT protocol permitted in situ imaging with good image quality and automated segmentation of vertebral bodies in the whole range from T6 to L4. The duration of bisphosphonate treatment was significantly associated with increased levels of mineralization and this effect could be measured with HRQCT performed on excised specimens. Microstructural parameters contributed to vertebral bone strength modelled by FE analysis independently of bone mineral density. The new QUS tibia scanner permitted measuring the acoustical anisotropy of reference materials. Taken together, these results document that new methods developed in BioAsset permit a more comprehensive assessment of bone fragility. The set of donor specimens with a documented history of bisphosphonate treatment allows for the assessment of the effects of long-term treatment from the organ down to the tissue and material level. These results will ultimately be linked to the parallel clinical study to provide guidance for determining the optimum duration of bisphosphonate treatment to reduce the incidence of osteoporotic fractures.

Abstract
BACKGROUND AND PURPOSE Cognitive rehabilitation has demonstrated efficacy in producing short-term cognitive and brain changes in patients with Parkinson's disease (PD). To date, no study has assessed the long-term effects of cognitive rehabilitation using neuroimaging techniques in PD. The aim was to assess the longitudinal effects of a 3-month cognitive rehabilitation programme evaluating the cognitive, behavioural and neuroimaging changes after 18 months. METHODS Fifteen patients with PD underwent a cognitive, behavioural and neuroimaging assessment at pre-treatment (T0 ), post-treatment (T1 ) and after 18 months (T2 ). This study examined the long-term effects (from T0 to T2 ) and the maintenance of the changes (from T1 to T2 ). T1-weighted, diffusion-weighted, functional magnetic resonance imaging during both a resting-state and a memory paradigm were acquired. Voxel-based morphometry and tract-based spatial statistics were used for grey and white matter analyses. A region-of-interest-to-region-of-interest approach was used for resting-state functional connectivity (FC) and a model-based approach was used for brain activation during the memory paradigm. RESULTS Patients with PD showed increased cognitive performance, decreased functional disability, increased brain FC and activation at T2 compared with T0 (P < 0.05, FDR). Moreover, patients showed maintenance of the improvements in cognition and functionality, and maintenance of the increased brain FC and activation at T2 compared with T1 . However, significant grey matter reduction and alterations of white matter integrity were found at T2 (P < 0.05, FWE). CONCLUSIONS Findings suggest that the improved cognitive performance and increased brain FC and activation after cognitive rehabilitation were significantly maintained after 18 months in patients with PD, despite the structural brain changes, consistent with a progression of neurodegenerative processes.

Abstract
Several experimental studies of obstructive jaundice (OJ) have shown the presence of immunosuppressive state associated with the rise of tumor necrosis factor-α (TNF-α) concentration in plasma. The present study evaluates the impact of anti-TNF-α administration or bile duct drainage on the inflammatory response, liver injury and renal insufficiency in obstructed rats. OJ was induced by the ligation of bile duct in Wistar rats. The parameters were determined at 14 and 21 days after OJ. Two additional groups of animals were treated with anti-TNF-α antibodies or submitted to bile duct drainage at 14 days, and sacrificed 21 days after OJ. Cholestasis decreased glucose, and enhanced urea, Creatinin, bilirubin and transaminases. Cholestasis increased the number of different inflammatory cells (T and B lymphocytes, and monocytes-macrophages) but reduced the expression of the corresponding cellular activation markers. This low responsiveness of the inflammatory cells was related to a decreased free radical production and phagocytic activity of cells. Anti-TNF-α and bile duct drainage reduced tissue injury, and prevented the reduction of the number and activity of T lymphocytes and phagocytic cells observed at the advanced stages of cholestasis. In conclusion, anti-TNF-α and bile duct drainage improved cell immunodeficiency, and reduced liver injury, cholestasis and renal insufficiency in experimental OJ.

Abstract
Our aim was to evaluate the killer cell immunoglobulin-like receptors (KIRs) as a marker for the development of thrombocytopenia secondary to Peg-interferon (IFN) therapy in a cohort of human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infected patients. Patients were naive to HCV treatment, receiving a first course of Peg-IFN/Ribavirin combination therapy. Total platelet count (cells ml-1) was determined at each visit, determining platelet decline from baseline to weeks 1, 2, 4, 8 and 12 after starting therapy. The end point of the study was development of thrombocytopenia, defined as a platelet count of <1 50 000 cells ml-1. Fifty-eight HIV/HCV co-infected patients were included in the study, of whom 20 (34.4%) developed thrombocytopenia. The absence of KIR2DS2 was associated with higher and faster rate of thrombocytopenia (54.2% vs 22.5%; P=0.012; 6.6 vs 10.3 weeks; P=0.008). The absence of KIR2DS2 was associated with a greater decline in platelet count and development of thrombocytopenia during Peg-IFN treatment in HIV/HCV co-infected patients.

Abstract
Anionic or non-ionic surfactants have been introduced in agarose-based hydrogels aiming to tailor the release of drugs with different solubility. The release of a hydrophilic model drug, Theophylline, shows the predictable release enhancement that varies depending on the surfactant. However, when the hydrophobic Tolbutamide is considered, an unexpected retarded release is observed. This effect can be explained not only considering the interactions established between the drug loaded micelles and agarose but also to the alteration of the freeze-dried hydrogels microstructure. It has been observed that the modification of the porosity percentage as well as the pore size distribution during the lyophilization plays a critical role in the different phenomena that take place as soon as desiccated hydrogel is rehydrated. The possibility of tailoring the pore architecture as a function of the surfactant nature and percentage can be applied from drug control release to the widespread and growing applications of materials based on hydrogel matrices.

Abstract
UNLABELLED Changes of the bone formation marker PINP correlated positively with improvements in vertebral strength in men with glucocorticoid-induced osteoporosis (GIO) who received 18-month treatment with teriparatide, but not with risedronate. These results support the use of PINP as a surrogate marker of bone strength in GIO patients treated with teriparatide. INTRODUCTION To investigate the correlations between biochemical markers of bone turnover and vertebral strength estimated by finite element analysis (FEA) in men with GIO. METHODS A total of 92 men with GIO were included in an 18-month, randomized, open-label trial of teriparatide (20 μg/day, n = 45) and risedronate (35 mg/week, n = 47). High-resolution quantitative computed tomography images of the 12th thoracic vertebra obtained at baseline, 6 and 18 months were converted into digital nonlinear FE models and subjected to anterior bending, axial compression and torsion. Stiffness and strength were computed for each model and loading mode. Serum biochemical markers of bone formation (amino-terminal-propeptide of type I collagen [PINP]) and bone resorption (type I collagen cross-linked C-telopeptide degradation fragments [CTx]) were measured at baseline, 3 months, 6 months and 18 months. A mixed-model of repeated measures analysed changes from baseline and between-group differences. Spearman correlations assessed the relationship between changes from baseline of bone markers with FEA variables. RESULTS PINP and CTx levels increased in the teriparatide group and decreased in the risedronate group. FEA-derived parameters increased in both groups, but were significantly higher at 18 months in the teriparatide group. Significant positive correlations were found between changes from baseline of PINP at 3, 6 and 18 months with changes in FE strength in the teriparatide-treated group, but not in the risedronate group. CONCLUSIONS Positive correlations between changes in a biochemical marker of bone formation and improvement of biomechanical properties support the use of PINP as a surrogate marker of bone strength in teriparatide-treated GIO patients.

Abstract
OBJECTIVE Decreased processing speed (PS) is a key feature of schizophrenia with respect to cognition, functional outcome and clinical symptoms. Our objective was to test whether PS slowing mediates other neuropsychological deficits among patients with chronic schizophrenia. METHOD One hundred patients with schizophrenia and 53 healthy adults completed a series of neuropsychological measures that assess six cognitive domains. In addition to PS these included attention, verbal memory, visual memory, working memory, and executive functioning. Confirmatory factor analysis (CFA) was used to evaluate the fit of the 6-factor model. The cognitive performances of both groups were compared before and after controlling for the effect of PS, but also after controlling for the effect of each cognitive factor at a time. Finally, the PS-related variance was removed and the effect of the other cognitive factors was tested again. RESULTS CFA supported the hypothesized 6-factor cognitive structure. As expected, the patients and controls differed on all cognitive measures. However, after controlling for the effects of PS, group differences on the other five cognitive factors decreased substantially. Controlling for other factors produced smaller attenuation of group differences, and these effects were also partially accounted for by decreased PS. CONCLUSIONS PS deficits account for most of the differences in cognition between patients with schizophrenia and healthy controls. PS slowing appears to be a core feature of schizophrenia, one that underlies impairments of working memory, executive functioning, and other abilities.

Abstract
PURPOSE Removal of the meniscus leads to progressive degenerative arthritis of the knee on a long-term basis; therefore, meniscal allograft transplantation has been proposed as an alternative to meniscectomy. Preservation methods are required to build up operational stocks and to provide living grafts of a practical size at the right time for patients. Methods for meniscus preservation have been published, and relevant literature confirms that using standard cryopreservation, the chondrocyte survival in situ is inadequate and extremely variable and the cryoinjury mechanisms are not completely established. The aim of the present study is to further investigate possible cellular injury caused by cryopreservation by analysing apoptosis and ultrastructural damage to menisci. METHODS Seven human menisci that were cryopreserved by standard method were used. All tissue samples were processed simultaneously for routine light microscopy, scanning and transmission electron microscopy as well as apoptosis assessment by the use of ISOL method. RESULTS With respect to cellularity, significant differences (P < 0.05) between the fresh (14.6 ± 3.5) (mean ± SD) and cryopreserved menisci (9.2 ± 2.8) (mean ± SD) were observed. Apoptosis using ISOL method was observed in fibrochondrocytes of fresh and cryopreserved menisci. The quantitative analysis revealed significant differences (P < 0.05) between fresh meniscus samples, where the apoptotic index was 0.8 ± 2.3% (mean ± SD), and cryopreserved meniscus samples, where this index was 50 ± 18.1% (mean ± SD). CONCLUSION The results suggest that apoptosis occurs during meniscus cryopreservation. The major findings of this study are cellular damage in meniscus cryopreservation suggesting apoptosis-mediated cell loss. The findings reported herein encourage to further investigations in preservation procedures to enhance maximum long-term clinical survival.

Abstract
IntroductionIt is well stablished that therapeutic compliance is a fundamental predictive factor in the outcome of first-episode psychosis. Risperidone long-acting injection has demonstrated high remission rates and improvements in treatment adherence.Objective1-To analyse the efficacy of risperidone long-acting injection vs oral atypical antipsychotics in first-episode psychosis.2-To describe in both groups the evolution of clinical and cognitive symptoms, functional outcome, quality of life, insight and treatment adherence.Method18 patients with a first-episode psychosis treated with long-acting risperidone were compared with 21 first-episode psychosis treated with oral atypical antipsychotic medication. They were matched one on one for age, gender and years of education. All subjects were compared regarding psychopathology and functional outcome terms. Patients were examined with Positive and Negative Syndrome Scale (PANSS) for clinical symptoms. Longitudinal functionality was prospectively assessed with the Clinical Global Impression (CGI) and Global Assessment of Functioning (GAF) rating scales.ResultsWe found significant differences between both groups in negative symptom severity and global assessment of functioning. There was no statistically significant difference between the two groups in PANSS positive and general components. Negative symptom severity was associated with poorer GAF ratings.ConclusionsOur data suggest that risperidone long-acting injection assures treatment compliance and therefore could improve clinical and functional outcome.

Abstract
OBJECTIVES The Eiffel study is a longitudinal, naturalistic study of patients with first episode psychosis (FEP) designed to evaluate the predictive value of defective insight on treatment adherence and global functioning. METHODS Five hundred seventy-seven patients with FEP were assessed at baseline and at a 1-year follow-up. They were compared in terms of sociodemographic factors, psychopathology, insight, treatment adherence and functional outcome. Longitudinal functionality was prospectively assessed with the clinical global impression (CGI) and global assessment of functioning (GAF) rating scales. RESULTS At baseline, up to 50% of our sample presented with a lack of insight. Most clinical symptoms, including insight, improved over the follow-up period. Insight, education and social withdrawal significantly predicted CGI and GAF at follow-up. Insight and level of education were predictive of treatment adherence. CONCLUSIONS Insight significantly predicted the general clinical course, treatment adherence and functional outcome in our FEP sample after 1 year. Only education additionally accounted for the longitudinal course. Since our results suggest that better insight improves treatment adherence and consequently clinical course and functional outcome, insight could be a specific target of treatment in early intervention programs.
