Abstract
Introduction: TULP1 exemplifies the remarkable clinical and genetic heterogeneity observed in inherited retinal dystrophies. Our research describes the clinical and molecular characteristics of a patient manifesting an atypical retinal dystrophy pattern, marked by the identification of both a previously unreported and a rarely encountered TULP1 variant. Methods: Whole-exome sequencing was performed to identify potential causative variants. The pathogenicity of the identified TULP1 variants was evaluated through in silico predictors and a minigene splice assay, specifically designed to assess the effect of the unreported TULP1 variant. Results: We identified two TULP1 gene variants in a patient exhibiting unusual and symmetrical alterations in both retinas, characterized by an increase in autofluorescence along the distribution of retinal vessels. These variants included a known rare missense variant, c.1376T>C, and a novel splice site variant, c.822G>T. For the latter variant (c.822G>T), we conducted a minigene splice assay that demonstrated the incorporation of a premature stop codon. This finding suggests a likely activation of the nonsense-mediated mRNA decay mechanism, ultimately resulting in the absence of protein production from this allele. Segregation analysis confirmed that these variants were in trans. Discussion: Our data support that individuals with biallelic TULP1 variants may present with a unique pattern of macular degeneration and periarteriolar vascular pigmentation. This study highlights the importance of further clinical and molecular characterization of TULP1 variants to elucidate genotype-phenotype correlations in the context of inherited retinal dystrophies.

Abstract
Extracellular vesicles (EVs) have become important in embryo-maternal communication during early development. The aim of this study was to evaluate the effect of an in vitro system on early bidirectional embryo-maternal communication mediated by EVs. For this purpose, two experiments were performed: one to evaluate the effect of embryonic EVs on maternal cells and the second to determine the effect of maternal EVs on early embryonic development. For the first in vitro (IVP) and in vivo (IVV) experiments, bovine blastocysts were selected and individually cultured for 48 h to collect embryonic EVs secreted during days 7-9 of embryonic development. Embryonic EVs were added to the medium of in vitro-cultured bovine endometrial cells to evaluate their effect on the expression pattern of genes associated with endometrial function and response to interferon tau (IFNT). Non-classical interferon-stimulated genes (ISGs) were only induced by in vitro-derived embryos. In the second experiment, EVs released by endometrial cells cultured in vitro (EVC) and collected from uterine fluid (EV-UF) of cows in the early luteal phase were added to the culture medium of bovine embryos produced in vitro during days 5-9 of development. The effect of maternal in vitro or in vivo-derived EVs differs in the quality of bovine embryos produced in vitro during the pre-implantation period. The expression of IFNT in bovine embryos is increased by the effect of EV-UF treatment. Additionally, EV-UF treatment induces a sustained increase in diameter during embryonic development and a tendency towards a greater number of expanded and hatched blastocysts. However, some genes related to embryo quality are induced by EVC treatment.

Abstract
BACKGROUND Hereditary hemorrhagic telangiectasia (HHT) is a rare vascular disease inherited in an autosomal dominant manner. Disease-causing variants in endoglin (ENG) and activin A receptor type II-like 1 (ACVRL1) genes are detected in around 90% of the patients; also 2% of patients harbor pathogenic variants at SMAD4 and GDF2. Importantly, the genetic cause of 8% of patients with clinical HHT remains unknown. Here, we present new putative genetic drivers of HHT. METHODS To identify new HHT genetic drivers, we performed exome sequencing of 19 HHT patients and relatives with unknown HHT genetic etiology. We applied a multistep filtration strategy to catalog deleterious variants and prioritize gene candidates based on their known relevance in endothelial cell biology. Additionally, we performed in vitro validation of one of the identified variants. RESULTS We identified variants in the INHA, HIF1A, JAK2, DNM2, POSTN, ANGPTL4, FOXO1 and SMAD6 genes as putative drivers in HHT. We have identified the SMAD6 p.(Glu407Lys) variant in one of the families; this is a loss-of-function variant leading to the activation of the BMP/TGFβ signaling in endothelial cells. CONCLUSIONS Variants in these genes should be considered for genetic testing in patients with HHT phenotype and negative for ACVRL1/ENG mutations.

Abstract
BACKGROUND Friedreich ataxia is the most common inherited ataxia in Europe and is mainly caused by biallelic pathogenic expansions of the GAA trinucleotide repeat in intron 1 of the FXN gene that lead to a decrease in frataxin protein levels. Rarely, affected individuals carry either a large intragenic deletion or whole-gene deletion of FXN on one allele and a full-penetrance expanded GAA repeat on the other allele. CASE PRESENTATION We report here a patient that presented the typical clinical features of FRDA and genetic analysis of FXN intron 1 led to the assumption that the patient carried the common biallelic expansion. Subsequently, parental sample testing led to the identification of a novel intragenic deletion involving the 5'UTR upstream region and exons 1 and 2 of the FXN gene by MLPA. CONCLUSIONS With this case, we want to raise awareness about the potentially higher prevalence of intragenic deletions and underline the essential role of parental sample testing in providing accurate genetic counselling.

Abstract
BACKGROUND Hereditary hemorrhagic telangiectasia (HHT) is a rare vascular disease inherited in an autosomal dominant manner. Disease-causing variants in endoglin (ENG) and activin A receptor type II-like 1 (ACVRL1) genes are detected in more than 90% of the patients undergoing molecular testing. The identification of variants of unknown significance is often seen as a challenge in clinical practice that makes family screening and genetic counseling difficult. Here, we show that the implementation of cDNA analysis to assess the effect of splice site variants on mRNA splicing is a powerful tool. METHODS Gene panel sequencing of genes associated with HHT and other arteriovenous malformation-related syndromes was performed. To evaluate the effect of the splice site variants, cDNA analysis of ENG and ACVRL1 genes was carried out. RESULTS three novel splice site variants were identified in ENG (c.68-2A > T and c.1311+4_1311+8del) and ACVLR1 (c.526-6C > G) genes correspondingly in three individuals with HHT that met ≥ 3 Curaçao criteria. All three variants led to an aberrant splicing inducing exon skipping (ENG:c.68-2A > T and ACVRL1:c.526-6C > G) or intron retention (ENG:c.1311+4_1311+8del) allowing the confirmation of the predicted effect on splicing and the reclassification from unknown significance to pathogenic/likely pathogenic of two of them. CONCLUSIONS RNA analysis should be performed to assess and/or confirm the impact of variants on splicing. The molecular diagnosis of HHT patients is crucial to allow family screening and accurate genetic counseling. A multidisciplinary approach including clinicians and geneticists is crucial when dealing with patients with rare diseases.

Abstract
Angelman syndrome (AS) is a neurogenetic disorder characterized by severe developmental delay with absence of speech, happy disposition, frequent laughter, hyperactivity, stereotypies, ataxia and seizures with specific EEG abnormalities. There is a 10–15% of patients with an AS phenotype whose genetic cause remains unknown (Angelman-like syndrome, AS-like). Whole-exome sequencing (WES) was performed on a cohort of 14 patients with clinical features of AS and no molecular diagnosis. As a result, we identified 10 de novo and 1 X-linked pathogenic/likely pathogenic variants in 10 neurodevelopmental genes (SYNGAP1, VAMP2, TBL1XR1, ASXL3, SATB2, SMARCE1, SPTAN1, KCNQ3, SLC6A1 and LAS1L) and one deleterious de novo variant in a candidate gene (HSF2). Our results highlight the wide genetic heterogeneity in AS-like patients and expands the differential diagnosis.

Abstract
Abstract
Introduction
Between the indications for endomyocardial biopsy (EMB) is the study of patients with heart failure associated with restrictive or infiltrative cardiomyopathy, such as cardiac amyloidosis if another workup is inconclusive. Although a risk-procedure, EMB is recommended in clinical scenarios in which the unique prognostic and diagnostic value of the information gained is felt to outweigh the procedural risks.
Purpose
We want to know the diagnostic value of EMB in the scenario of suspected cardiac amyloidosis and the role of the place of EMB for diagnosis.
Methods
We prospectively collected patients from our center with infiltrative cardiomyopathy and suspected cardiac amyloidosis who were referred to perform EMB. We gathered data on diagnostic profitability considering two different groups: those with samples from the right ventricle (group 1) and those with samples from the left ventricle (group 2; 90.8% with transradial approach). We consider major complications myocardial perforation, pericardial tamponade, arrhythmias, or bleeding with hemodynamic instability and death.
Results
We collected data from 111 patients referred for EMB for infiltrative cardiomyopathy suspicion. We present the results in table 1. The most common diagnosis was cardiac amyloidosis for wild-type transthyretin (43.48% in group 1 and 58.46% in group 2). There were no complications in the patients with confirmed cardiac amyloidosis in group 2.
Conclusions
In our EMBs for infiltrative cardiomyopathy suspicion we found that patients undergoing left-sided EMB had a shorter time of X-ray exposure and less time of admission without any other risk associated. So, we conclude that EMBs performed in the left heart are secure and comfortable for patients and physicians.

Abstract
KIF1A is a microtubule-dependent motor protein responsible for fast anterograde transport of synaptic vesicle precursors in neurons. Pathogenic variants in KIF1A have been associated with a wide spectrum of neurological disorders. Here, we report a patient presenting a severe neurodevelopmental disorder carrying a novel de novo missense variant p.Arg169Thr (R169T) in the KIF1A motor domain. The clinical features present in our patient match with those reported for NESCAV syndrome including severe developmental delay, spastic paraparesis, motor sensory neuropathy, bilateral optic nerve atrophy, progressive cerebellar atrophy, epilepsy, ataxia, and hypotonia. Here, we demonstrate that the microtubule-stimulated ATPase activity of the KIF1A is strongly reduced in the motor domain of the R169T variant. Supporting this, in silico structural modeling suggests that this variant impairs the interaction of the KIF1A motor domain with microtubules. The characterization of the molecular effect of the R169T variant on the KIF1A protein together with the presence of the typical clinical features indicates its causal pathogenic effect.

Introduction
Primary prevention of sudden cardiac death is the main indication for ICD implantation, mainly based on left ventricular ejection fraction (LVEF). Gender differences in the diagnosis and treatment of some cardiology conditions such as myocardial infarction have been previously established.
Purpose
We aim to analyze differences in prognostic variables that could justify gender differences in the non-prescription of an ICD for primary prevention.
Methods
A retrospective selection of patients from our center during 2019 with ventricular systolic dysfunction (LVED ≤35% in an echocardiogram) was made. We included patients at least one month after an acute myocardial infarction and with optimal medical treatment without an ICD. Death was considered during the year 2019.
Results
We initially selected 325 patients with ventricular dysfunction, of wich 175 fulfilled the inclusion criteria (67.4% men and 32.6% women). ICD indication was considered in 47 patients out of the 175 selected (29.7% among men and 21.1% among women, p = 0.7; 70.3% among men and 78.9% among women, p= 0.30 for non-prescription). The index left ventricle end-diastolic volume (iLVEDV) was significantly worse in males. Females were older and had lower LVEF.
Conclusion
Although it is a unicenter study and we have only performed univariate comparisons, without considering confounding factors, we found no significant gender differences in prognostic variables that could justify differences in the non-prescription of an ICD for primary prevention.

Abstract
The objective of this study was to evaluate, in the domestic cat, the effect of ovarian stimulation with eCG prior to oocyte in vitro maturation (priming) on in vitro and in vivo development after in vitro fertilization (IVF). For this purpose, oocyte donors were either 1) treated with a single dose of 200 IU eCG four days before oocyte recovery (eCG group), or, 2) given no treatment before oocyte recovery (control group). Ovaries of both groups were collected by ovariohysterectomy (OVH) and cumulus-oocyte complexes (COCs) were recovered by slicing. Immature COCs from both groups were matured in vitro (IVM) for 26-28 h. IVF was done with refrigerated epididymal sperm. After 24 h co-incubation, presumptive zygotes were cultured in vitro for eight days. The rates of cleavage, morulae, blastocyst development and hatching were estimated. Some blastocysts were stained for total cell counting and others were used for gene expression analysis of pluripotency (OCT4, SOX2 and NANOG) and differentiation markers (CDX2 and GATA6). Additionally, to evaluate in vivo development, embryos from the eCG group were transferred at Day 5 and Days 7 or 8 of IVC to synchronized cat recipients. The results showed that, eCG priming increased significantly the rate of blastocyst development as compared to the control group (37.9 and 25.6%, respectively) (P < 0.05). No differences were observed in total cell number of blastocysts and hatching blastocysts (mean ± SD) between the eCG and control groups (420.6 ± 193.6 and 347.0 ± 237.1, respectively) (P > 0.05). In the gene expression analysis, blastocysts generated in the eCG group had higher expression of OCT4 than blastocysts from the control group (P < 0.05). However, no significant differences were observed in the relative expression of SOX2, NANOG, CDX2 and GATA6 (P > 0.05). Additionally, six embryo transfer (ET) procedures were done, three with Day 5 embryos and three with Day 7 or 8 embryos. Recipients from both ET groups delivered live kittens. The total pregnancy rate was 4/6 (67%), meanwhile the live birth rate was 2/6 (33%). In conclusion, eCG priming improved the rate of blastocyst development in vitro and increased relative expression of OCT4. These results demonstrate that eCG priming of oocytes donors before IVM improves oocyte competence, enhance in vitro embryo development and allows live births of healthy offspring after ET.

Abstract
Noninvasive methods are the clue to increase the efficiency of invitro-derived embryo selection without decreasing their competence. Embryos selection based on their morphology is the most used method but only 40% of selected embryos are able to implant and develop correctly. In humans, pre-implantation genetic diagnosis increases the efficiency of selection by excluding embryos with chromosomal abnormalities. However, pre-implantation genetic diagnosis needs embryonic cells, which might compromise embryo viability. On the other hand, embryos release extracellular vesicles (EVs: microvesicles and exosomes) to the culture medium that contain biological cargo-like proteins and mRNA lipids, and might contain genomic DNA (gDNA). For this study we evaluated the culture medium from embryos generated by intracytoplasmic sperm injection in a certified fertility clinic. Embryos were cultured in Global Total serum-free medium. The embryos were assessed at Day 3 of development and classified in three categories: top, fair, and poor quality. Corresponding medium was collected for isolation of EVs. The nature of EVs was confirmed by their size and concentration using nanoparticle tracking analysis (NTA), presence of surface markers (CD9, CD63, CD81, and CD40L), and morphology using transmission electron microscopy. A correlation analysis between NTA results (EV size and concentration) and embryo quality was performed. To evaluate chromosomal abnormalities of gDNA present in isolated EVs from embryo culture medium, microarray-based comparative genomic hybridization (aCGH) assay was performed. In a second experiment, aCGH analysis was performed and compared between arrested embryos and EVs isolated from corresponding culture medium. Isolated nanoparticles from embryo culture medium were positive to all markers CD9 (30.9%), CD63 (27.2%), CD81 (31.7%), CD40L (8.7%) and had a morphology accordingly to exosomes. The analysis of NTA data indicated that top-quality embryos had EVs with higher diameter (mean: 112.17nm, mode: 91.74nm) than embryos classified as fair (mean: 108.02nm, mode: 89.67nm) and poor quality (mean: 102.78nm, mode: 88.17 nm; P<0.05). The aCGH analysis showed the representation of the 23 pairs of chromosomes in EVs from culture medium and the chromosomal abnormalities were detected in chromosome 4 (C4: 6/15 (40%)) and chromosome 13 (C13: 6/15 (40%)). In the second experiment, the aCGH assay also showed abnormalities in different chromosomes from samples of EVs from culture medium (24.9%) and were more frequent than those observed in the arrested embryos (8.7%; P=0.03). However, the rate of similitude in chromosomal abnormalities between EVs and their respective embryo was 70-80%. In conclusion, the size and gDNA of EVs from culture medium might be an alternative to evaluate the competence of human embryos.

Abstract
Limited information have been reported regarding to the role of the zona pellucida during embryo development in the domestic cat. In the present research we compared invitro and invivo development of cat embryos generated with versus without the zona pellucida. Embryos were produced by IVF and cultured up to blastocyst stage accordingly to experimental group: 1) with intact zona pellucida (ZI) and 2) without zona pellucida (ZF). Ovaries of domestic cats were collected by ovariohysterectomy and cumulus-oocyte complexes (COCs) were recovered by slicing. For IVM, COCs were cultured in supplemented medium-199 for 26-28h in a 5% CO2, 5% O2, and 90% N2 atmosphere at 38.5°C. For IVF, 1.5-2.5×106 epididymal spermatozoa/mL were incubated with 20-30 COCs in supplemented Tyrode's albumin lactate pyruvate medium for 18h in a 5% CO2 atmosphere at 38.5°C. The zona pellucida of the presumed zygotes was removed by 2-4min of incubation in 2mgmL−1 pronase. In ZI and ZF groups, embryo culture was done in 4-well dishes; in the ZF group the well of the well system was used. The IVC was done in supplemented synthetic oviductal fluid medium, in a 5% CO2, 5% O2, and 90% N2 atmosphere at 38.5°C for 8 days. The frequencies of cleavage and development to the morula and blastocyst stages were determined. The relative expression of the pluripotency markers OCT4, SOX2, and NANOG was evaluated by RT-qPCR in the blastocysts using the standard curve method. The SDHA gene was used as internal control. Additionally, the invivo development was evaluated. For this, cat recipients were synchronized with 200IU equine chorionic gonadotrophin followed by 100IU human chorionic gonadotrophin 4 days later, and embryo transfers (ET) were made by mid-ventral laparotomy. The Wilcoxon nonparametric test was used to evaluate the developmental competence and the gene expression analysis. Nine and six replicates were performed in the ZI and ZF groups, respectively. No differences were observed between the ZI and ZF groups in the cleavage rate: 155/239 (64.9%) and 116/177 (65.5%), morulae rate: 115/155 (74.2%) and 68/116 (58.6%), and blastocysts rate: 51/155 (32.9%) and 36/116 (31.0), respectively (P>0.05). No differences were observed in the expression of OCT4 (P>0.05). However, the expression of SOX2 and NANOG was lower in blastocysts from the ZF group than in those from the ZI group (P<0.05). Finally, three ET were done at the blastocyst stage in both groups. In the ZI group, 8-16 Day 7 blastocysts were transferred per cat, two pregnancies were obtained with one gestational sac in each cat (2/3, 66.6%), and one live kitten was born at Day 64 of pregnancy (1/3, 33.3%). In the ZF group, 7-14 were transferred per cat, and no pregnancies were obtained after ET. In conclusion, in the domestic cat, zona pellucida removal at the presumed zygote stage did not affect invitro development to blastocyst but affect negatively the expression of SOX2 and NANOG. However, the low survival after ET of ZI embryos is a possible indicator that embryo quality might be affecting survival rates. Nonetheless, these results add credence to previous ET studies that provide indirect evidence of a crucial role of the zona pellucida for successful implantation of cat embryos.

Abstract
Reprogramming of terminally differentiated cells to higher plasticity levels can be achieved with small molecules. This can be of value for somatic cell nucleus transfer, deriving multi and pluripotent cells and conservation purposes. Recently, induced mesenchymal stem cells were derived from differentiated human and mouse cells by using small molecules and growth factors. The pampas cat or colocolo (Leopardus colocolo) is a South American felid categorrized as near threatened by the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Major historical threats to the pampas cat include illegal hunting, habitat loss or transformation, and conflict retaliation for poultry predation. Here, we tested 5-azacytidine (an epigenetic modifier) and A8301 (a potent inhibitor of transforming growth factor-β type I receptor superfamily), linked to platelet-rich plasma (PRP) and platelet-derived growth factor (PDGF-B) to induce changes in the expression of pluripotency genes and differentiation capacity of colocolo fibroblasts towards other mesodermal lineages. For this, dermal fibroblasts were treated with (I) 5-azacytidine + PRP + A8301 + VitC, or (II) 5- azacytidine + VitC + A8301 + PDFG for 12 days. On Days 0, 5, and 12 of reprogramming, expression of OCT4, NANOG, E-cadherin and SNAIL was evaluated by reverse transcription-PCR, and tri-lineage differentiation was induced. For treatment I, no statistical difference was found in the expression of OCT4 and NANOG. Chondrogenic and osteogenic differentiation was observed. In treatment II, significant expression of OCT4 and NANOG (P<0.05) was induced, and reprogrammed fibroblasts were differentiated into chondrogenic and osteogenic lineages. Immunohistochemistry positivity for OCT4 was detected in treatment II. In summary, we showed that dermal fibroblasts of pampas cat can be reprogrammed into cells with multipotent characteristics, particularly when a cocktail of 5-azacytidine + VitC + A8301 + PDFG was used. Treatment I probably failed because of other growth factors and proteins present in PRP, which might inhibit successful reprogramming or activate other pathways leading to a nonmultipotent phenotype. Further refinements of these protocols are required to improve the reprogramming protocol. This in turn should help us obtain cells that can be used in nucleus transfer or cellular therapies in endangered felid species.

Abstract
The kodkod is considered a vulnerable species by the International Union for Conservation of Nature. Phylogenetically, the kodkod is classified in the Leopardus genus, which has only 36 chromosome pairs compared with the domestic cat, which has 38. The proposed hypothesis was that domestic cat oocytes are capable of reprogramming somatic cells from kodkod after interspecies somatic cell NT (SCNT), allowing the in vitro embryo development up to blastocyst stage. Five experimental groups were made based on the technology and culture system: (1) cat embryos generated by IVF (IVF), (2) cat embryos generated by SCNT (Ca1x), (3) aggregated cat embryos generated by SCNT (Ca2x), (4) kodkod embryos generated by interspecies SCNT (K1x), and (5) aggregated kodkod embryos generated by interspecies SCNT (K2x). Interspecies SCNT was performed using a zona-free method. Reconstructed embryos were activated by 2 electrical pulses of 140 kV cm−1 for 40 µs and then incubated for 5h in 10μg mL−1 of cycloheximide and 5μg mL−1 of cytochalasin B. Embryos were cultured in SOF media using the well of the well system in a 5% O2, 5% CO2, and 90% N2 atmosphere at 38.5°C for 8 days. The morulae and blastocysts rates were estimated, and diameter of cloned blastocysts was measured. The relative expression of OCT4, SOX2, and NANOG was evaluated in blastocysts by RT-qPCR using the standard curve method; SDHA was used for normalization. The Kruskal-Wallis test was used to evaluate the developmental parameters and gene expression. The t-test was used to evaluate blastocyst diameter. Statistical differences were considered at P<0.05. The number of replicates was IVF=10, Ca1x=8, Ca2x=6, K1x=3, and K2x=8. The morulae rate was lower when clone embryos were cultured individually (IVF=97/153, 63.4%; Ca2x=28/51, 54.9%; K2x=63/110, 57.3%; Ca1x=48/126, 38.1%; K1x=22/87, 25.3%; P<0.05). In the domestic cat, blastocysts rate was higher in IVF (58/153, 37.9%) and Ca2x (28/51, 29.4%) groups than in the Ca1x group (21/126, 16.7%; P<0.05). No blastocysts were generated in the K1x group (0/87), whereas 5.5% of blastocysts were obtained from the K2x (6/110; 5.5%); this was not statistically different compared with the K1x group (P>0.05). No differences were found in blastocyst diameter between the Ca1x (220.4µm) and Ca2x (251.2µm) groups (P>0.05). However, the diameter of the blastocysts from the K2x group (172.8µm) tended to be lower than that of the blastocysts from the Ca2x group (P=0.05). Regarding gene expression, only 1 of the 6 kodkod blastocysts expressed OCT4, and none expressed SOX2 and NANOG. On the other hand, the relative expression of OCT4 tended to decrease in blastocysts from the Ca1x and Ca2x groups compared with the IVF group (P=0.09), but no differences were found in the expression of SOX2 and NANOG among groups (P>0.05). In conclusion, after interspecies SCNT, domestic cat oocytes support the development of kodkod embryos until the morula stage. However, the embryo aggregation did not significantly improve the blastocyst rate and gene expression.

Abstract
BACKGROUND Patients affected by Angelman syndrome (AS) present severe intellectual disability, lack of speech, ataxia, seizures, abnormal electroencephalography (EEG), and a characteristic behavioral phenotype. Around 10% of patients with a clinical diagnosis of AS (AS-like) do not have an identifiable molecular defect. Some of these patients harbor alternative genetic defects that present overlapping features with AS. METHODS Trio whole-exome sequence was performed on patient and parent's DNA extracted from peripheral blood. Exome data were filtered according to a de novo autosomal dominant inheritance. cDNA analysis was carried out to assess the effect of the splice site variant. RESULTS We identified a novel heterozygous SMARCE1 splicing variant that leads to an exon skipping in a patient with an Angelman-like phenotype. Missense variants in the SMARCE1 gene are known to cause Coffin-Siris syndrome (CSS), which is a rare congenital syndrome. Clinical reevaluation of the patient confirmed the presence of characteristic clinical features of CSS, many of them overlapping with AS. CONCLUSIONS Taking into account the novel finding reported in this study, we consider that CSS should be added to the expanding list of differential diagnoses for AS.

Abstract
BACKGROUND Patients with Angelman syndrome (AS) are affected by severe intellectual disability with absence of speech, distinctive dysmorphic craniofacial features, ataxia and a characteristic behavioral phenotype. AS is caused by the lack of expression in neurons of the UBE3A gene, which is located in the 15q11.2-q13 imprinted region. Functional loss of UBE3A is due to 15q11.2-q13 deletion, mutations in the UBE3A gene, paternal uniparental disomy and genomic imprinting defects. CASE PRESENTATION We report here two patients with clinical features of AS referred to our hospital for clinical follow-up and genetic diagnosis. Methylation Specific-Multiplex Ligation-Dependent Probe Amplification (MS-MLPA) of the 15q11.2-q13 region was carried out in our laboratory as the first diagnostic tool detecting two novel UBE3A intragenic deletions. Subsequently, the MLPA P336-A2 kit was used to confirm and determine the size of the UBE3A deletion in the two patients. A review of the clinical features of previously reported patients with whole UBE3A gene or partial intragenic deletions is presented here together with these two new patients. CONCLUSION Although rare, UBE3A intragenic deletions may represent a small fraction of AS patients without a genetic diagnosis. Testing for UBE3A intragenic exonic deletions should be performed in those AS patients with a normal methylation pattern and no mutations in the UBE3A gene.

Abstract
BACKGROUND AND PURPOSE Current protocols in patients with glioblastoma include performing an MR examination shortly after surgery and then 2-6 weeks after ending concomitant chemoradiotherapy. The assessment of this first postradiotherapy examination is challenging because the pseudoprogression phenomenon may appear. The aim of this study was to explore if performing an MR examination shortly before radiation therapy (preradiotherapy MR imaging) could improve the radiologic assessment of patients with glioblastoma. MATERIALS AND METHODS A preradiotherapy MR imaging examination was prospectively performed before the start of radiation therapy in 28 consecutive patients with glioblastoma who had undergone surgical resection. Tumor response to chemoradiotherapy was assessed twice: with the early postoperative MR examination as baseline and with the preradiotherapy MR imaging examination as baseline. In addition, tumor growth in the preradiotherapy MR imaging examination was evaluated, and its correlation with patient survival was assessed with Kaplan-Meier analysis and Cox regression. RESULTS Tumor progression after radiation therapy was found in 16 patients, corresponding to pseudoprogression in 7 of them (44%). Four assessments of pseudoprogression switched to partial response or stable disease when preradiotherapy MR imaging was the baseline examination, and the ratio of pseudoprogression was reduced to 25% (3 of 12). Significant differences in survival were found when patients were stratified according to the pattern of tumor growth on preradiotherapy MR imaging (median overall survival "no-growth," 837 days; "focal-growth," 582 days; "global-growth," 344 days; P = .001). CONCLUSIONS Performing a preradiotherapy MR imaging examination may improve the clinical management of patients with glioblastoma by reducing the ratio of pseudoprogression assessments and providing prognostic information.

Abstract
The diagnosis of smoldering multiple myeloma (SMM) includes patients with a heterogeneous risk of progression to active multiple myeloma (MM): some patients will never progress, whereas others will have a high risk of progression within the first 2 years. Therefore, it is important to improve risk assessment at diagnosis. We conducted a retrospective study in a large cohort of SMM patients, in order to investigate the role of Bence Jones (BJ) proteinuria at diagnosis in the progression to active MM. We found that SMM patients presenting with BJ proteinuria had a significantly shorter median time to progression (TTP) to MM compared with patients without BJ proteinuria (22 vs 88 months, respectively; hazard ratio=2.3, 95% confidence interval=1.4-3.9, P=0.002). We also identified risk subgroups based on the amount of BJ proteinuria: ⩾500 mg/24 h, <500 mg/24 h and without it, with a significantly different median TTP (13, 37 and 88 months, P<0.001). Thus, BJ proteinuria at diagnosis is an independent variable of progression to MM that identifies a subgroup of high-risk SMM patients (51% risk of progression at 2 years) and ⩾500 mg of BJ proteinuria may allow, if validated in another series, to reclassify these patients to MM requiring therapy before the end-organ damage development.

Abstract
Background Biotechnological agents (BA) are increasingly being used in clinical practice. We aimed to determine, whether enquiries about them to a therapeutic consultation service have also become more frequent, and to describe the information requested in these consultations. Methods We retrospectively reviewed 14 104 therapeutic consultations collected in a computerised database between 2000 and 2014. Enquiries about BA (monoclonal antibodies, fusion proteins or cytokine antagonists) were chosen. Information on the type of BA, underlying condition, type of enquiry and affiliation of the enquirer was retrieved and compared with data from consultations about other agents. Results During the study period, 365 enquiries about 30 different BA were received. Only 4% of them were received before 2004, while 48.8% were received after 2010. Rituximab, infliximab, adalimumab and etanercept were most frequently enquired about. Agent selection (n=184) and/or adverse effects (n=174) were the most frequent reasons for making an enquiry. Most enquiries about an agent selection were made about an off-label use (n=164), mainly for systemic autoimmune diseases (n=61). Over half of the enquiries about adverse effects were about their teratogenic potential (n=96). Enquiries about BA more often requested an opinion (87.7% vs 77.7%) were made by physicians (89.9% vs 76.9%), from a hospital (81.6% vs 44.5%) and regarded a specific patient (87.4% vs 74.5%). Conclusions Therapeutic consultations about BA are increasing. Most of them are related to uncertainties of health professionals regarding any new medicine: their off-label use, actual adverse effects or the teratogenic potential of the involved agents.

Abstract
Three homologous series of polymethylene-α,ω-bis[2-thio-5(4′,4″n-alkoxybenzoyloxy)- phenyl]-1,3,4-oxadiazole (series 5 a, b, c), are reported.The compounds have identical mesogenic units at both ends of a spacer (i.e. they are twins). These twins possess a spacer of 6, 8 and 10 carbon atoms joined directly to the oxadiazole ring through sulphur atoms. The lateral alkylic chains vary between 6 and 10 carbon atoms.The presence of enantiotropic and monotropic nematic phase is related to the length of the spacer group. The influence of molecular structure on the mesomorphic properties has been studied. Mesomorphic properties and phase transitions have been determined using polarizing hot-stage microscopy and differential scanning calorimetry.

Abstract
BACKGROUND AND PURPOSE There is a large range of survival times in patients with HGA that can only be partially explained by histologic grade and clinical aspects. This study aims to retrospectively assess the predictive value of single-voxel (1)H-MRS regarding survival in HGA. MATERIALS AND METHODS Pretreatment (1)H-MRS in 187 patients with HGA produced 180 spectra at STE (30 ms) and 182 at LTE (136 ms). Patients were dichotomized into 2 groups according to survival better or worse than the median. The spectra of the 2 groups were compared using the Mann-Whitney U test. The points on the spectrum with the most significant differences were selected for discriminating patients with good and poor prognosis. Thresholds were defined with ROC curves, and survival was analyzed by using the Kaplan-Meier method and the Cox proportional hazards model. RESULTS Four points on the spectrum showed the most significant differences: 0.98 and 3.67 ppm at STE; and 0.98 and 1.25 ppm at LTE (P between <.001 and .011). These points were useful for stratifying 2 prognostic groups (P between <.001 and .003, Kaplan-Meier). The Cox forward stepwise model selected 3 spectroscopic variables: the intensity values of the points 3.67 ppm at STE (hazard ratio, 2.132; 95% CI, 1.504-3.023), 0.98 ppm at LTE (hazard ratio, 0.499; 95% CI, 0.339-0.736), and 1.25 ppm at LTE (hazard ratio, 0.574; 95% CI, 0.368-0.897). CONCLUSIONS (1)H-MRS is of value in predicting the length of survival in patients with HGA and could be used to stratify prognostic groups.

Abstract
BACKGROUND AND PURPOSE Differentiating between tumors and pseudotumoral lesions by conventional MR imaging may be a challenging question. This study aims to evaluate the potential usefulness and the added value that single-voxel proton MR spectroscopy could provide on this discrimination. MATERIALS AND METHODS A total of 84 solid brain lesions were retrospectively included in the study (68 glial tumors and 16 pseudotumoral lesions). Single-voxel spectra at TE 30 ms (short TE) and 136 ms (long TE) were available in all cases. Two groups were defined: "training-set" (56 cases) and "test-set" (28 cases). Tumors and pseudotumors were compared in the training-set with the Mann-Whitney U test. Ratios between resonances were defined as classifiers for new cases, and thresholds were selected with receiver operating characteristic (ROC) curves. The added value of spectroscopy was evaluated by 5 neuroradiologists and assessed with the Wilcoxon signed-rank test. RESULTS Differences between tumors and pseudotumors were found in myo-inositol (mIns); P < .01) at short TE, and N-acetylaspartate (NAA; P < .001), glutamine (Glx; P < .01), and choline (CHO; P < .05) at long TE. Classifiers suggested tumor when mIns/NAA ratio was more than 0.9 at short TE and also when CHO/NAA ratio was more than 1.9 at long TE. Classifier accuracy was tested in the test-set with the following results: short TE, 82% (23/28); long TE, 79% (22/28). The neuroradiologists' confidence rating of the test-cases on a 5-point scale (0-4) improved between 5% (from 2.86-3) and 27% (from 2.25-2.86) with spectroscopy (mean, 17%; P < .01). CONCLUSIONS The proposed ratios of mIns/NAA at short TE and CHO/NAA at long TE provide valuable information to discriminate between brain tumor and pseudotumor by improving neuroradiologists' accuracy and confidence.

Abstract
BACKGROUND AND AIMS Between 10 and 15% of all cases of colorectal cancer are the result of microsatellite instability (MSI) in the genetic pathway due to an alteration in the DNA repair genes. Tumors with high MSI are characterized by a better prognosis. The BRAF oncogene has been linked to the MSI pathway in tumorogenesis. The objective of this study was to determine whether alterations in BRAF are related to MSI and whether they can result in differences in survival rates. METHODS The study cohort comprised 351 patients diagnosed with sporadic colorectal cancer. MSI was determined in accordance with the National Cancer Institute's (NCI) recommendations by means of PCR and sequence analyses. Mutational analysis of the BRAF gene was performed by real-time PCR and subsequent sequencing of the altered samples. The methylation pattern of the hMLH1 gene was determined using methylation-specific PCR analyses of bisulfite-treated DNA and the results confirmed by sequencing. RESULTS Of the patients tested, 6.9% showed high MSI and 3.7% showed a BRAF gene mutation. hMLH1 methylation was observed in 67.2% of the patients with MSI and/or the BRAF alteration. The BRAF mutation was related to the MSI genetic pathway (P < 0.0001) and with hMLH1 methylation. In the analysis of overall survival only MSI had an independent prognostic value for the risk of death. Patients with the BRAF mutation showed a higher risk of death, although this association was found not to be statistically significant. CONCLUSIONS There is a subgroup of carcinomas which develop via the MSI pathway that carry an alteration of the BRAF gene. This alteration confers a poorer outcome on these patients within the total group of patients with MSI who have a better prognosis. This hypothesis should be further investigated in a larger study population due to the low incidence of BRAF mutations in colorectal cancer.

Abstract
Nuclear functions for IkappaB kinase (IKK), including phosphorylation of histone H3 and nuclear corepressors, have been recently described. Here, we show that IKK is activated in colorectal tumors concomitant with the presence of phosphorylated SMRT (silencing mediator of retinoic acid and thyroid hormone receptor) corepressor that is aberrantly localized in the cytoplasm. In these tumors, IKKalpha associates to the chromatin of specific Notch targets, leading to the release of SMRT. Abrogation of IKK activity by BAY11-7082 or by expressing dominant negative IKKalpha restores the association of SMRT with Notch target genes, resulting in specific gene repression. Finally, BAY11-7082 significantly reduces tumor size in colorectal cancer xenografts (CRC-Xs) implanted in nude mice.

Abstract
Fluorescence in situ hybridisation (FISH) is an effective technique for the cytogenetic analysis of Waldenström macroglobulinemia (WM), but the potential impact of molecular cytogenetics on disease evolution and as a prognostic marker is still unknown. Deletion of the long arm of chromosome 6 (6q-) is the most frequent cytogenetic abnormality in WM. This study analysed the prevalence of this aberration in 102 WM patients, and correlated it with disease characteristics. The incidence of 6q21 deletion was 7% by conventional cytogenetics and 34% when analysed by FISH (54% when cytoplasmic immunoglobulin M-FISH was used). Patients with deletion of 6q displayed features of adverse prognosis, such as higher levels of beta2-microglobulin and monoclonal paraprotein and a greater tendency to display anaemia and hypoalbuminemia. Interestingly, there was a correlation between the presence of 6q deletion and the International Staging System prognostic index (incidence of 6q- among patients stratified in stages 1, 2 and 3 was 24%, 42% and 67% respectively). Those patients diagnosed with smouldering WM who displayed the abnormality showed a trend to an earlier requirement of treatment. Finally, the survival analysis did not show differences between the two groups of patients, probably due to the short follow up of our series.

Abstract
OBJECTIVE To assess analgesic drugs in the treatment of postoperative pain after traumatic and orthopaedic surgery (TOS). DESIGN A systematic review of randomised clinical trials (RCTs). DATA SOURCES Electronic PubMed, EMBASE, The Cochrane Library, and hand searches. STUDY SELECTION RCTs of analgesics administered by oral, intramuscular, intravenous, subcutaneous or rectal route, were compared to other analgesics or placebo, in patients under TOS. Study design, characteristics of the study population, analgesic drugs tested, pain intensity and pain relief scores, and adverse effects were assessed. RESULTS Ninety-two RCTs (9,596 patients) met our inclusion criteria. Forty-two (46%) were placebo-controlled, and 50 (54%) were direct comparisons between non-opioid, opioid, and/or combinations of both. Patients' mean age (SD) was 49 years (18). In most trials, gastrointestinal ulcer, liver and renal diseases were exclusion criteria. Only 30 trials (33%) were double-blind and reported standardised outcomes of pain intensity and pain relief; 19 of these were single-dose, and follow up of analgesic effects lasted no more than 12 h in 23 (77%). Globally, only nine trials (10%) were double blind, described dropouts or withdrawals, performed analysis by intention to treat, and reported the effects magnitude. CONCLUSION Evidence from RCTs on the treatment of postoperative pain after TOS is inadequate for clinical decision making. Assessment of analgesics in pain after TOS should be based on agreed clinically relevant outcomes, in representative patients, and for longer observation periods. In addition, it should include direct comparisons between candidate drugs or their combinations and between various drug administration schedules.

Abstract
AIM To describe the opinions of hospital physicians concerning problems regarding the spontaneous reporting of adverse drug reactions (ADRs) and ways to solve them. METHODS A qualitative study was carried out. Fifteen focus groups were conducted among physicians working in a tertiary teaching hospital. A total of 208 physicians from different medical specialities participated. The focus group discussions were recorded by three different observers and the transcripts of each session were analysed for issues and themes emerging from the text. RESULTS Four types of obstacles to spontaneous reporting were considered particularly important: (i) problems with the ADR(S) diagnosis; (ii) problems with the usual workload and lack of time; (iii) problems related to the organization and activities of the pharmacovigilance system; (iv) and problems related to potential conflicts. The potential solutions suggested for improving spontaneous reporting were to define the kind of ADR(S) which should be reported, to facilitate an easy contact and quick access to the hospital pharmacovigilance system, to facilitate information and support for reporting and feedback of pharmacovigilance activities. CONCLUSIONS The perception of the different obstacles by the hospital physicians is an important factor in determining the causes of the underreporting of ADRs and addressing these obstacles could lead to an improvement in spontaneous reporting. A closer relationship between the doctors and the pharmacovigilance centre is suggested as a means of solving these problems. More information is needed to improve the spontaneous reporting of ADR(S) in specialized healthcare.

Abstract
Paraoxonase 1 (PON 1) is an esterase with antioxidant properties that is present in HDL. Gln192Arg polymorphism (also named Q192R or Q/R) of the PON 1 gene that encodes this protein defines two alleles (Q and R). The R allele has been associated with higher cardiovascular risk. LDL size and susceptibility to oxidation also have been identified as cardiovascular risk factors. Our objective was to determine whether genetic variations in the Gln192Arg polymorphism influence LDL size and susceptibility to oxidation after the consumption of diets with different fat content. In our experiments, the participants (n = 98) underwent three 4-wk diets--one, saturated fat-enriched (SAT); another, monounsaturated fat-enriched (MONO); and a third, carbohydrate-enriched (CHO). We observed that LDL were smaller in the QQ group after the CHO diet vs. the SAT (P < 0.01) and MONO diets (P < 0.03). No differences in LDL size were found in QR/RR subjects. When we analyzed lag time of oxidation of LDL, we found that when carriers of the R allele (QR/RR) received the MONO diet, the lag period of LDL oxidation was longer as compared with the CHO diet. Otherwise, we found no differences in QQ homozygotes when we evaluated the lag time of oxidation of LDL after the three diets. These results suggest that the Glnl92Arg polymorphism of the paraoxonase gene influences LDL size and susceptibility to oxidation in response to diet.
