Does elite European match-play affect salivary immunoglobulin-A and cortisol in soccer players? The influence of playing status and match outcome

Introduction: The aims of this study were to: a) investigate salivary immunoglobulin A (s-IgA) and cortisol (s-Cort) responses to nine competitive fixtures in starting and non- starting soccer players; and b) compare s-IgA and s-Cort responses of starters and non-starters considering match outcome. Methods: Saliva from 19 male outfield players from an elite soccer team (mean ± SD, age 26 ± 4 years; weight 80.5 ± 8.1 kg; height 1.83 ± 0.07 m; body-fat 10.8% ± 0.7%) was collected. Saliva samples were taken on the day before each match (MD-1), 60-min before kick-off (MDpre), 30-min post-match (MDpost), and 72-h post-match (MD+3). There were five wins, one draw and three losses. Results: The mean s-IgA value was found to be significantly lower at MD+3 compared to MDpre and MDpost. s-Cort was significantly higher at MDpost compared to MD-1 and MDpre. When compared to MDpre, a statistically significant decrease in s-Cort was observed at MD+3 compared to MDpost. Starters displayed higher s-Cort values across the nine matches. There was a significant group-by-time interaction for s-Cort. There was a significant increase in s-Cort levels at MDpost compared to MD-1 and from MDpre to MDpost in starting players. At MDpost, starters had significantly higher s-Cort values. s-IgA values of starting and non- starting players following successful and unsuccessful matches did not reveal a significant difference. However, similar analysis of s-Cort in successful matches showed a significant difference between starters and non-starters. s-IgA values at MD-1, MDpre, MDpost and MD+3 in starters and non-starters following successful and unsuccessful matches revealed significant differences at MDpre and MDpost in starters, respectively. Furthermore, s-Cort values at MD-1, MDpre, MDpost and MD+3 in starters and non-starters in successful and unsuccessful matches revealed significant differences at MD+3 in starting players. Discussion: The present study suggests that in elite level soccer players, both starting status and match outcome influence s-IgA and s-Cort responses, particularly starters. Specifically, s-IgA was lower for starters before and after the match following successful outcomes. Moreover, higher s-Cort values were found before the match while lower values occurred after the match for starters in successful matches.

Spatio-temporal interactions between the red fox and the wolf in two contrasting European landscapes

Relationships among carnivore species are complex, potentially switching from competition to facilitation on a context-dependent basis. Negative associations are predicted to increase with latitude, due to limited resources emphasising competition and/or intra-guild predation. Accordingly, a stronger negative correlation between large- and meso-carnivore abundances should be expected at higher latitudes, with a substantial spatio-temporal partitioning favouring interspecific coexistence. Human presence may influence spatio-temporal relationships between (meso)carnivore species, as it can be perceived as a risk factor, but anthropogenic food can also provide an important additional food resource. Using camera-trap data, we studied the spatio-temporal associations between two of the most widespread carnivores in Europe, i.e., the red fox and wolf. We compared their monthly/daily spatio-temporal partitioning between two different landscapes: Białowieża Primeval Forest (Poland) and the Mediterranean Maremma Regional Park (Italy). We predicted a stronger interspecific partitioning, as well as more attraction of red foxes to humans in the northern site (Poland). Temporal activity patterns of the two carnivores overlapped in both sites, and their detection rates were positively associated, even though in weaker way in Poland. We observed a positive spatial association of red foxes with human activity in Białowieża, but not in Maremma. This association occurred only at a monthly temporal scale and disappeared at a daily scale, suggesting some disturbance in the shorter term. Our results provided partial support to our predictions and suggest that, despite the ecological differences between our study areas, only weak differences in wolf-fox relations were observed, suggesting that red fox responses to wolves may be relatively comparable over large spatial scales.

Balanced chromosomal rearrangements implicate YIPF5 and SPATC1L in non-obstructive oligoasthenozoospermia and oligozoospermia and of a derivative chromosome 22 in recurrent miscarriage

Naturally occurring balanced, unbalanced, and complex chromosomal rearrangements have been reported to cause pathogenic genomic or genetic variants leading to infertility and recurrent miscarriage. Therefore, balanced chromosomal rearrangements were used as genomic signposts for identification of candidate genes or genomic loci associated with male infertility due to defects of spermatogenesis, or with recurrent miscarriage. In three male probands, structural chromosomal variants and copy number variants were identified at nucleotide resolution by long-insert genome sequencing approaches and Sanger sequencing. The pathogenic potential of these and affected candidate genes was assessed based on convergent genomic and genotype-phenotype correlation data. Identification of balanced chromosomal rearrangement breakpoints and interpretation in the context of their genomic background of structural and copy number variants led us to conclude that the infertility due to oligoasthenozoospermia and oligozoospermia is most likely associated with a position effect on YIPF5 and SPATC1L, respectively. In a third proband with intellectual disability and recurrent miscarriage, disruption of CAMK2B causing autosomal dominant, intellectual developmental disorder 54 and increased meiotic segregation during gametogenesis of a der(22) are responsible for the reported phenotype. Our data further support the existence of loci at 5q23 and 21q22.3 for these spermatogenesis defects and highlight the importance of the naturally occurring balanced chromosomal rearrangements for assessment of the pathogenic mechanisms. Furthermore, we show comorbidities due to the same balanced chromosomal rearrangement caused by different pathogenic mechanisms.

Exploring the prevalence and antibiotic resistance profile of Klebsiella pneumoniae and Klebsiella oxytoca isolated from clinically ill companion animals from North of Portugal

Klebsiella spp. is an important pathogen in humans and animals and due to the indiscriminate use of antibiotics, its prevalence and antibiotic resistance has increased in companion animals. The main goal of this study was to investigate the prevalence and antibiotic resistance of Klebsiella spp. isolated from clinically ill cats and dogs admitted in veterinary clinics in the North of Portugal. A total of 255 clinical specimens were collected and, after isolation, the identification of Klebsiella strains was performed using the BBL Crystal™ identification system and confirmed by PCR-based sequencing with specific primers. Antibiotic resistance profile was determined through the disc diffusion method. Beta-lactam resistance genes were screened through a multiplex PCR assay. Fifty Klebsiella strains were isolated and, 39 were identified as Klebsiella pneumoniae and 11 as Klebsiella oxytoca. Thirty-one were recovered from dogs and 19 from cats. The Klebsiella isolates were recovered mainly from skin wounds, respiratory tract, and from urine. Fifty percent of K. oxytoca and K. pneumoniae isolates revealed to be Multidrug Resistant (MDR) strains, with most of them positive for the presence of blaTEM-like and blaSHV genes. This data shows that MDR Klebsiella are highly disseminated in companion animals and that extended-spectrum beta-lactamases can be easily found among these isolates. This highlights the potential role of dogs and cats as a reservoir of resistant Klebsiella spp. that have the potential to be transmitted to humans.

Modification of [18F]-FDG PET/CT imaging protocols in obese oncology patients: A nationwide survey

INTRODUCTION

The use of medical imaging for diagnosis, staging and follow-up in Oncology context is incredibly important, being the use of [18F]-FDG PET/CT particularly advantageous in specific contexts like the case of obese patients. However, imaging the latter can be challenging sometimes, since their own body size may affect overall image quality and adds technical difficulties for the operator(s) performing the examination.

METHODS

This research project was developed with the aim of analysing the current personal practices of Portuguese Nuclear Medicine Technologists (NMTs) in the adaptation of ¹⁸F-FDG PET/CT oncological protocols for obese patients and comparing the results with parameters referenced in literature. A non-experimental research study was conducted using a survey delivered online to NMTs through social media platforms (Facebook® and LinkedIn®) and by sending the link directly to contacts within the research team professional and personal networks.

RESULTS

Answers from a total of 26 participants were obtained, with 88.5% of participants admitting modifying technical protocols in examinations for obese patients. Changes in PET protocols included an increase in the administered activity (60.9%), an increase in scan time per individual bed position (69.6%) and the use of Time-of-Flight (TOF) technology whenever available. Protocol changes in CT included increasing the mA (82.6%), raising the KVp (47.8%), the application of iterative reconstruction (69.6%) and the use of automatic exposure control (AEC) (52.2%). The remaining parameters (pitch, algorithm, slice thickness, display FOV, gantry rotation time and energy acceptance window) were claimed not to be modified by around 90% of professionals.

CONCLUSION

Portuguese NMTs tend to change the [18F]-FDG PET/CT protocols for obese patients. However, while some of the parameters appear to be contradictory or redundant, others require further optimisation, especially in the CT component.

IMPLICATIONS FOR PRACTICE

Efforts should be made to optimize acquisition protocols used in [18F]-FDG PET/CT scans for obese patients.

BIODEGRADABLE SODIUM CARBOXYMETHYL CELLULOSE MEMBRANES CONTAINING MELALEUCA ESSENTIAL OILS FOR WOUND CARE MATERIAL

NaCMC is a biocompatible polymer that can be crosslinked with citric acid to form a gel matrix. Melaleuca oils have antimicrobial and anti-inflammatory properties with potential for wound healing. The goal of this work was to investigate the characteristics of NaCMC-Melaleuca oils gels. The gels were characterized by FTIR, TGA, mechanical analysis, and in vitro swelling and S. aureus inhibition tests. The oils were characterized using chromatography, presenting high values of (1,8 cineol/terpinen-4-ol), and evaluated for confirmation of their effect against S. aureus. The samples showed physical interactions between NaCMC, citric acid and the Melaleuca oils. Erosion in saline solution was higher in the gels with oils, attributable to interference with crosslinking. The membranes presented high contribution of relaxation mechanism and low contribution of Fickian diffusion regarding the swelling ability. The presence of the oils increased thermal stability and diminished gel fraction and mechanical properties, indicating that the oils interact with the matrix anchoring the chains. Although melaleuca oils themselves were active against S. aureus and CA was responsible for the NaCMC hydrogels activity, the incorporation of melaleuca oils in NaCMC gels was not reported previously. This report indicates that NaCMC hydrogel may be a proper matrix for essential oils incorporation.

Transcranial Doppler findings in a population with clinical probable reversible cerebral vasoconstriction syndrome

OBJECTIVE

To describe transcranial Doppler (TCD) findings in a population with clinical probable RCVS. Exploratory objectives included the study of clinical characteristics of probable RCVS patients with and without spasm detected by TCD.

METHODS

Cross-sectional cohort study of patients with thunderclap headache (TCH) without subarachnoid hemorrhage (SAH) of our neurology and headache center between 2010 and 2019, selecting patients with clinical diagnosis of probable RCVS (negative angiography study) by ICHD-3 criteria and with at least two TCD studies.

RESULTS

From 114 TCH patients, 36/114 had probable RCVS by ICHD-3 criteria and had at least two TCD studies available. The mean age at RCVS onset was 42.9years (21-72years); 29/36 (80.6%) were female, 7/28 (25%) had cardiovascular risk factors and 20/36 (55.6%) had history of migraine. Most common triggers were stressful emotion, drugs, valsalva maneuvers and sexual activity. Five/36 (13.9%) had complications and 3/36 (8.3%) had late recurrence. Initial TCD was performed on average of 16 (6-26) days after headache onset. Twenty-nine had vasospasm on TCD, presenting mean flow velocity of MCA (VMCA) of 135.7±17.0cm/s and mean maximum VMCA of 138.3±17.2. Vasospasm was mild in 21/29 patients (72.4%) and moderate in 8/29 (27.6%). Complete VMCA normalization occurred on average 41 (30-70) days after headache onset and 24 (11-47) days after initial TCD. The group of patients with vasospasm detected by TCD had more female patients (26/29, 89.7% vs. 3/7, 42.8%, P=0.016), and more TCH attacks (mean of 3.6 vs. 2.14, P=0.049).

CONCLUSION

TCD may be a useful tool in the identification of vasospasm in patients with probable RCVS, supporting the diagnosis of RCVS in patients presenting with recurrent TCH without SAH.

Molecular profiling of osteosarcoma in children and adolescents from different age groups using a next-generation sequencing panel

Osteosarcoma (OS) is a malignant bone tumor, with a peak of incidence in the second decade of life and possibly associated with the presence of germline mutations. Besides, clinicians have pointed to a second, rarer group of patients that develops OS before 10 years old. Here we access, through next-generation sequencing (NGS) strategy, the genetic alterations present in OS and blood samples from patients diagnosed before and during the second decade of life. A custom NGS panel, designed for the main alterations described in childhood and adolescence neoplasms, named Oncomine Childhood Cancer Research Assay (OCCRA©), was used. Of all 84 OS samples investigated, 42 (50%) presented some somatic variant, with TP53, MYC, CDK4, RB1 and PDGFRA genes harboring the most observed genetic variants. MYC CNVs were more frequent in tumors from patients diagnosed before 10 years old (X²₁= 5.18, p = 0.023). Additionally, patients diagnosed during the second decade of life presented a higher percentage of somatic and germline variants. Germline variants in TP53 and RB1 were found in 5 of the 11 (45.5%) patients analyzed. Clinical variables and tumor histopathological characteristics were also collected and correlated with our molecular findings.

Gynaecological cytology in women under the age of 30—the impact of P16/KI67 dual-staining cytology

Background

The HPV detection test is not recommended as a primary screening of cervical lesions, before the age of 30, because the high rate of HPV infections with a high rate of spontaneous resolution in this age group. This study aims to evaluate the performance of p16/Ki67 dual staining in detecting high-grade squamous cervical lesions in these women.

Methods

Cervical-vaginal samples from 67 women HPV positives under the age of 30 and cervical biopsies of 41 of these women. Results of p16/Ki67 dual staining, cytology and histology were analysed. In 53 of the women, 159 results of p16/Ki67 dual staining, HPV test and cytology, obtained in 3 follow-up medical visit, were compared.

Results

The p16/ki67 dual staining was positive in 23.9% and negative in 76.1% of all 67 women. All women with high squamous intraepithelial lesion cytology, 39.1% with low squamous intraepithelial lesion cytology, 17.4% with negative for intraepithelial lesion cytology and 10% with atypical squamous cells cytology, were p16/Ki-67 dual staining positives. In the 41 women with histological diagnosis, p16/ki67 dual staining showed a sensitivity of 87.5% and a specificity of 96% to detect HSIL. When comparing, the tests differ significantly (P < 0.001), p16/ki67 dual staining was positive in 24% of positive cytology and in 19.5% of positive HPV tests.

Conclusions

Our results demonstrate that p16/Ki67 dual stain has good sensitivity and specificity to detect HSIL and can be useful on women under the age of 30, avoiding excessive diagnosis and reducing colposcopy referrals. Further studies are required in a large number of women.

Cone dystrophy with supernormal rod responses: A rare KCNV2 gene variant

PURPOSE

To describe the clinical, electrophysiological, and genetic findings of three Portuguese families with a rare variant in the KCNV2 gene resulting in "cone dystrophy with supernormal rod responses" (CDSRR).

METHODS

Retrospective clinical revision of five individuals from three unrelated families with CDSRR. Ophthalmological examination was described in all patients and included color vision testing, fundus photography, fundus autofluorescence (FAF) imaging, spectral domain-optical coherence tomography (SD-OCT), pattern electroretinogram (ERG), and full-field ERG. The mutational screening of the KCNV2 gene was performed with Sanger and Next Generation Sequencing.

RESULTS

All patients showed childhood-onset photophobia and progressive visual acuity loss with varying degrees of severity. In multimodal imaging, various degrees of retinal pigment epithelium disturbances and outer retinal atrophy, which tend to be worst with advancing age, were observed. Molecular screening identified a rare presumed truncating variant (p.Glu209Ter) in homozygosity in two families and in compound heterozygosity in a third family. Three patients showed ERG changes characteristic of CDSRR, however, two patients presented with incomplete electrophysiological features of the disease.

CONCLUSION

A rare variant in the KCNV2 gene was identified in five patients from three Portuguese families. This variant often leads to a severe and progressive form of retinopathy. Considerable variability in the ERG responses among patients with this KCNV2 variant was observed.

Recommendations for genetic testing in cardiology: Review of major international guidelines

In recent years, the importance of genetic causes of cardiovascular diseases has been increasingly recognized, as the result of significant advances in molecular diagnosis techniques. This growing knowledge has enabled the identification of new phenotypes and the subclassification of clinical syndromes, impacting the therapeutic approach and genetic counseling offered to affected families. This paper describes the state of the art of genetic testing in the main cardiovascular diseases, aiming to provide a useful tool to help cardiologists and other health professionals involved in the care of individuals with hereditary heart diseases and their families.

Blood biomarkers associated with inflammation predict poor prognosis in cerebral venous thrombosis:: a multicenter prospective observational study

BACKGROUND AND PURPOSE

Experimental studies suggest inflammation can contribute to blood barrier disruption and brain injury in cerebral venous thrombosis (CVT). We aimed to determine whether blood biomarkers of inflammation were associated with the evolution of brain lesions, persistent venous occlusion or functional outcome in patients with CVT.

METHODS

Pathophysiology of Venous Infarction-Prediction of Infarction and Recanalization in CVT (PRIORITy-CVT) was a multicenter prospective cohort study of patients with newly diagnosed CVT. Evaluation of neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) concentrations in peripheral blood samples was performed at admission in 62 patients. Additional quantification of interleukin (IL)-6 was performed at day 1, 3 and 8 in 35 patients and 22 healthy controls. Standardized magnetic resonance imaging was performed at day 1, 8 and 90. Primary outcomes were early evolution of brain lesion, early recanalization and functional outcome at 90 days.

RESULTS

Interleukin-6 levels were increased in patients with CVT with a peak at baseline. IL-6, NLR and CRP levels were not related with brain lesion outcomes or early recanalization but had a significant association with unfavourable functional outcome at 90 days (IL-6: OR = 1.28, 95% CI: 1.05-1.56, P = 0.046; NLR: OR = 1.39, 95% CI: 1.4-1.87, P = 0.014; CRP: OR = 1.756, 95% CI: 1.010-3.051, P = 0.029). Baseline IL-6 had the best discriminative capacity, with an area under the receiver operating characteristic curve to predict unfavourable functional outcome of 0.74 (P = 0.031).

CONCLUSIONS

Increased baseline levels of NLR, CRP and IL-6 may serve as new predictive markers of worse functional prognosis at 90 days in patients with CVT. No association was found between inflammatory markers and early evolution of brain lesion or venous recanalization.

Complex movement disorder in a patient with heterozygous YY1 mutation (Gabriele-de Vries syndrome)

YY1 mutations cause Gabriele-de Vries syndrome, a recently described condition involving cognitive impairment, facial dysmorphism and intrauterine growth restriction. Movement disorders were reported in 5/10 cases of the original series, but no detailed description was provided. Here we present a 21-year-old woman with a mild intellectual deficit, facial dysmorphism and a complex movement disorder including an action tremor, cerebellar ataxia, dystonia, and partial ocular apraxia as the presenting and most striking feature. Whole-exome sequencing revealed a novel heterozygous de novo mutation in YY1 [NM: 003403.4 (YY1): c.907 T > C; p.(Cys303Arg)], classified as pathogenic according to the ACMG guidelines.

Cognitive appraisal in fish: stressor predictability modulates the physiological and neurobehavioural stress response in sea bass

The role of cognitive factors in triggering the stress response is well established in humans and mammals (aka cognitive appraisal theory) but very seldom studied in other vertebrate taxa. Predictability is a key factor of the cognitive evaluation of stimuli. In this study, we tested the effects of stressor predictability on behavioral, physiological and neuromolecular responses in the European sea bass (Dicentrarchus labrax). Groups of four fish were exposed to a predictable (signalled) or unpredictable (unsignalled) stressor. Stressor predictability elicited a lower behavioural response and reduced cortisol levels. Using the expression of immediate early genes (c-fos, egr-1, bdnf and npas4) as markers of neuronal activity, we monitored the activity of three sea bass brain regions known to be implicated in stressor appraisal: the dorsomedian telencephalon, Dm (putative homologue of the pallial amygdala); and the dorsal (Dld) and ventral (Dlv) subareas of the dorsolateral telencephalon (putative homologue of the hippocampus). The activity of both the Dm and Dlv significantly responded to stressor predictability, suggesting an evolutionarily conserved role of these two brain regions in information processing related to stressor appraisal. These results indicate that stressor predictability plays a key role in the activation of the stress response in a teleost fish, hence highlighting the role of cognitive processes in fish stress.

Renal Dysplasia and Progressive Renal Failure in a Newborn with Interstitial Chromosome 4 Deletion 4q25-28.3: A New Phenotype?

The deletion of the long arm of chromosome 4 is rare, presenting with a variable phenotype depending on the chromosomic area affected. A term newborn with prenatal diagnosis of anhydramnios, dysplastic cystic kidneys, and cardiomegaly was born with generalized subcutaneous edema, several dysmorphic features, and progressive renal failure requiring dialysis. The infant continued to deteriorate and died at 52 days of age. Autopsy confirmed bilateral renal dysplasia with cysts. Array-comparative genomic hybridization (CGH) identified a large deletion on 4q25-q28.3, which is not yet described in association with renal disease. The clinical progression could be expected due to the severity of the perinatal clinical presentation.

Task-Based Automatic Evaluation of People with Intellectual Disabilities Performed on a Robotic Table Soccer

This paper is concerned with the automatic evaluation of selected tasks performed by people with intellectual Disabilities. According to the International Classification of Functioning, Disability and Health (ICF) system, subjects must be divided into two groups: group with no difficulty (N) and group with difficulty (D) being this classification based on performances obtained in a conventional table (CT) soccer. Three tasks, with different levels of difficulty, were proposed for performance evaluation. Experimental results were obtained on the basis of the task execution in both a CT and a robotics table (RT) soccer. All participants were able to perform tasks with the joystick on the RT soccer and the automatic evaluation system identified differences in reaction times with and without red color flag in the participants, on RT soccer. One of the tasks was completely performed by all the participants by using the RT soccer.

CYP21A2 Gene Pathogenic Variants: A Multicenter Study on Genotype-Phenotype Correlation from a Portuguese Pediatric Cohort

BACKGROUND

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is an autosomal recessive disorder characterized by 3 overlapping phenotypes: salt-wasting (SW), simple virilizing (SV), and non-classic (NC). We aimed at conducting a nationwide genotype description of the CAH pediatric patients and to establish their genotype-phenotype correlation.

METHODS

CAH patients were recruited from Portuguese pediatric endocrinology centers and classified as SW, SV, or NC. Genetic analysis was performed by polymerase chain reaction (sequence specific primer, restriction fragment length polymorphism) or direct Sanger sequencing. Genotypes were categorized into 4 groups (0, A, B, and C), according to their predicted enzymatic activity. In each group, the expected phenotype was compared to the observed phenotype to assess the genotype-phenotype correlation.

RESULTS

Our cohort comprises 212 unrelated pediatric CAH patients (29% SW, 11% SV, 60% NC). The most common pathogenic variant was p.(Val282Leu; 41.3% of the 424 alleles analyzed). The p.(Val282Leu) variant, together with c.293-13A/C>G, p.(Ile173Asn), p.(Leu308Thr), p.(Gln319*), and large deletions/conversions were responsible for 86.4% of the mutated alleles. Patients' stratification by disease subtype revealed that the most frequent pathogenic variants were c.293-13A/C>G in SW (31.1%), p.(Ile173Asn) in SV (46.9%), and p.(Val282Leu) in NC (69.5%). The most common genotype was homozygosity for p.(Val282Leu; 33.0%). Moreover, we found 2 novel variants: p.(Ile161Thr) and p.(Trp202Arg), in exons 4 and 5, respectively. The global genotype-phenotype correlation was 92.4%. Group B (associated with the SV form) showed the lowest genotype-phenotype correlation (80%).

CONCLUSION

Our cohort has one of the largest NC CAH pediatric populations described. We emphasize the high frequency of the p.(Val282Leu) variant and the very high genotype-phenotype correlation observed.

Análise do poder de discriminação de índices prognósticos em pacientes queimados

Introdução: As queimaduras são um grave problema de saúde pública. Os índices prognósticos estimam probabilidade prognóstica e ajudam a quantificar a gravidade do paciente. Objetivo: Avaliar o poder de discriminação dos índices Abbreviated Burn Severity Index (ABSI), Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential Organ Failure Assessment (SOFA) e Therapeutic Intervention Scoring System 28 (TISS 28) da admissão em pacientes de uma Unidade de Terapia Intensiva (UTI) especializada no tratamento de queimados. Casuística e Métodos: Estudo longitudinal prospectivo, realizado em uma Unidade de Terapia Intensiva especializada no atendimento ao paciente queimado, no período de maio de 2011 a maio de 2013. Foram excluídos pacientes com menos de 18 anos e com menos de 24 horas de internação. Foram coletados dados clínicos e demográficos e calculados os escores prognósticos estudados. A acurácia dos índices foi avaliada pela curva Receiver Operating Characteristic (ROC), discriminando o desfecho do paciente (sobrevivente e não sobrevivente). Foi calculada a área sob a curva (AUC). Resultados: Foram incluídos 180 pacientes no período de estudo, sendo 72,8% do sexo masculino (n=131). A mediana de idade foi de 40 anos (ITQ: 30 – 52,5). A mortalidade hospitalar foi de 37,2% (n=67). A maior AUC foi a do escore APACHE II, com valor de 0,837 (ponto de corte do escore = 14, sensibilidade de 83,6% e especificidade de 72,3%). Na análise de pontuação dos escores entre sobreviventes e não sobreviventes, observou-se diferença estatisticamente significativa entre os valores de todos os índices estudados. Conclusões: Os escores ABSI, APACHE II, SOFA e TISS 28 na admissão da UTI mostraram bom poder de discriminação para sobrevivência entre pacientes queimados.

Influence of Ischemia Time in Injury of Deep Peribiliary Glands of the Bile Ducts Graft: A Prospective Study

The deep peribiliary glands (DPBG) are a niche of progenitor cells in the wall of the biliary duct (BD) and are the second line of multiplication when severe lesion of the epithelium occurs. Previous studies have identified DPBG injury as a cause of post-liver transplant (LT) biliary stenosis; this complication is a major cause of post-LT morbidity. The incidence of biliary stenosis in our center is high (38.1%). This study evaluates the lesion of DPBG in response to ischemia. Graft BD was collected in adult LT between August 2016-July 2017, from donation after brain death. Samples of 45 grafts were collected at 2 moments: BD1-during graft preparation and BD2-before biliary anastomosis. Histological analysis of the samples was performed and then classified according to degree of lesion (0, ≤50%, and >50%). A comparison was made between the degree of lesion and graft ischemia, graft histology, donor, and procurement variables. The DPBG lesion was more frequent in BD2 (20.9% vs 7%, P = .079). BD2 lesions with DPBG lesions had higher medians and means at all times of ischemia. The difference was greater in the warm ischemia time (0: 43.3 ± 12.53 minutes vs ≤50%: 52.4 ± 14.38 minutes, P = .068). The group of BD1 with DPBG lesion presented superior median cold ischemia time (CIT). In the analysis of the remaining variables there were also no statistically significant differences. We concluded that during the period of CIT there is already lesion of the DPBG, which increases after reperfusion of the graft, in greater association with longer warm ischemia time.

Inflammatory bowel diseases: time of diagnosis, environmental factors, clinical course, and management - a follow-up study in a private inflammatory bowel disease center (2003-2017)

BACKGROUND

The governmental program of Brazilian Unified National Health System has already published studies on the incidence of inflammatory bowel diseases (IBD), but up until now, there have been no epidemiological studies in private centers in Brazil. However, these diseases tend to affect people from a higher socioeconomic class, mainly in the capital of MS state that has the third highest GDP in Brazil.

OBJECTIVES

The aim was to analyze an observational, descriptive study of an IBD database in a private center including: the side, behavior of the disease and medical management, the association of extra-intestinal manifestations, and the main clinical symptoms which led to the investigation and diagnosis of IBD.

PATIENTS AND METHODS

A cohort study was developed in which data of all patients with IBD were analyzed with SPSS software in a constructed electronic database.

RESULTS

Of 329 patients, 212 (64.4%) had Crohn's disease (CD) and 117 (35.6%) had ulcerative colitis (UC). Average age at diagnosis of CD was 36.19 (±14.33) and of UC was 41.61 (±15.37). An amount of 50.05% of the patients with CD and 72.7% (P<0.001) with UC were female. We have observed that concerning the first symptoms, diahrrea and blood feces corresponded to 70% in UC while in CD 50% of the patients presented diahrrea with blood feces, loss of weight corresponded to 50% and only diahrrea 25%. (P<0.001). Anti-TNFs corresponded to 56.2% being more frequent in CD 0.001%. CD patients used biologic therapy and antibiotics more frequently than those with UC. In conclusion, IBD is also frequent in private health care centers in Brazil; women are most affected. Symptoms such as diarrhea and bleeding, as well as diarrhea and weight loss, must be taken as warning signs to investigate for inflammatory disease. The use of biologic therapies is frequent in referral centers when patients have severe disease.

MON-250 Chromosomal Microarray Analysis in Patients with Central Precocious Puberty Associated with Dysmorphic Features or Congenital Malformations

Introduction: Central precocious puberty (CPP), defined as the onset of pubertal signs before the age of 8 in girls and 9 in boys, results from the premature reactivation of the hypothalamic-pituitary-gonadal axis. CPP is familial in as many as 27.5% of the cases, which supports a genetic origin of this disorder. Currently, monogenic defects associated with CPP include inactivating mutations in MKRN3 and rare defects in KISS1, KISS1R and DLK1. In addition, CPP has been associated with complex genetic syndromes resulting from distinct chromosomal abnormalities as Silver-Russel Syndrome and Temple Syndrome. However in many patients its genetic basis remains unknown. Objective: To investigate pathogenic copy number variations (CNVs) in patients with idiopathic CPP associated with dysmorphic features or congenital malformations. Methods: A cohort of 45 patients with idiopathic CPP was initially evaluated for mutations in the coding region of MKRN3. Subsequently, 3 patients screened negative for MKRN3 mutations and with additional dysmorphisms or congenital malformations were selected for chromosome microarray analysis (CMA) using the Affymetrix CytoScan 750k according to manufacturer’s protocols. Results: In patient 1 (P1), a boy presenting CPP at the age of 8 associated with autism spectrum disorder and overweight, a pathogenic previously described heterozygous microdeletion at 16p11.2 (761 kbp), and a microduplication at 18p11.22 (363kbp), a variant of unknown significance (VOUS), were detected. His younger brother, who also has ASD and was recently diagnosed with CPP, also carried the same CNVs. Patient 2 (P2) was a monozygotic twin boy with a past history of hypospadia, an angular deformity of the femur, and pubertal onset at age of 6.5years. His monozygotic twin was equally affected and both developed polycythemia in the beginning of the second decade of life. CMA revealed a heterozygous duplication of 155kbp at 7p15.2, classified as VOUS. The third case (P3), a girl with idiopathic CPP associated with congenital heart disease, exhibited no significant chromosomal rearrangements, except for blocks of homozygosity due to parental consanguinity. Conclusion: Our results underscore the relevance of CMA in the investigation of patients with CPP associated with syndromic features. Parental consanguinity can also be identified by CMA and is associated with an increased risk of congenital anomalies, as was the case of P3. The 16p11.2 microdeletion has been previously associated with ASD, however CPP has not been previously reported in these patients. Further studies are needed to address possible associations between CPP and the CNVs and/or genes presented inside these variant regions identified in P1 and P2.

MON-581 Pediatric Patients with Celiac Disease Present Higher Risk of Developing Endocrine and Other Autoimmune Disorders Than Adults

Background: Celiac Disease (CD) is an autoimmune intestinal disorder triggered by gluten exposure in genetically predisposed individuals. It is well described its association with other autoimmune diseases (AIDs), mainly type 1 diabetes mellitus (T1DM) and autoimmune thyroiditis (AT). Age and sex seem to have a role in driving the risk pattern for developing other AIDs among individuals with CD throughout life. Objectives: To study the prevalence of AIDs among pediatric and adult individuals with CD and recognize clinical parameters potentially correlated to such association. Methods: Retrospective study of medical records followed by telephone interview with individuals with CD followed at the Gastroenterology Unit of a tertiary level University hospital. Results: We assessed 328 patients, 235 (72%) females, currently aged from 2 to 74 years (yr), mean age at CD diagnosis (CD-dx) 22 yr (±15.6). From the total, 72 patients (22%) presented at least one associated AID, being 47 females (65.3%), and the CD-dx of this subgroup was 32.5 yr (±12.0). Thirty-one patients presented T1DM (43%): 16 females, mean CD-dx 9 yr (±8.5). Twenty-two patients (30.5%) presented associated AT (Graves' disease or Hashimoto's thyroiditis): 14 females (66.3%), mean CD-dx 35.2 yr (±25.5). Dermatitis herpetiformis was present in 17 patients (23.6%): 12 females (70.6%), mean CD-dx 29.8 yr (± 0.7). Systemic lupus erythematosus was present in 3 patients (4.2%), all females, mean CD-dx 37.5 yr (±7.8). Eight patients (10.8%) presented more than two associated AIDs: 4 females; mean CD-dx 20 yr (±1.4). The overall mean time between the diagnosis of CD and the second AID was 4.3 yr (±2.8). The individuals whose diagnosis of CD was in pediatric ages presented a 72% higher risk of developing a second autoimmunity (p=0.005) compared to adults. The risk of developing T1DM among male celiac patients was 76% higher than females (p=0.013), regardless of age. The risk of developing a third immunity was also 3.2 times higher in males (p=0.047). Conclusion: Although other non-celiac AIDs were more prevalent among females, males are at higher risk for developing T1DM as well as a third autoimmunity. The pediatric group showed to be more vulnerable to develop subsequent AIDs than adults. Those data strength the importance of clinical and serological screening for other AIDs among patients with CD, especially children and adolescents.

SAT-319 Long-term Follow-up of Two Unrelated Boys With SDHB-Related Malignant Paragangliomas

Background: Paragangliomas (PGLs) are rare neuroendocrine cell tumors and due to its rarity, there is no current standardized treatment and optimal long-term follow-up for metastatic disease. We report two cases of SDHB-related malignant PGL in boys with more than 5 years of follow-up. Clinical case: Patient 1 (P1) presented at the age of 13 with hypertension crisis, after a history of paroxystic tachycardia and sweating since 9. Fractionated 24-hour urinary metanephrines showed high Normetanephrine (NMT). CT showed bilateral lung lesions, the largest in right basis (6.1x5.3cm) in close contact with the 7/8th ribs and vertebrae, enlarged thoracic lymph nodes, and a 2.2 cm tumor near the left carotid. The patient went through a debulking surgery of the tumors. Patient 2 (P2) presented with abdominal pain at the age of 7. CT showed an abdominal tumor that was surgically resected. In both cases immunohistochemistry was compatible with PGL. P2 tumor was a non-secreting PGL, with high plasma chromogranin A prior to surgery. Both subsequently developed multiple bone metastases, and in case 2, additional recurrent retroperitoneal metastases. Adjuvant therapeutic ¹³¹I-MIBG, until a total dose of 900mCi (P1) and 950mCi (P2,) was performed. Over a 5- and 7-year follow-up, respectively, sustained stable disease has been documented, with control of tumor burden, despite the presence of several metastatic foci, mostly in bones. P1 has maintained mild hypertension controlled with diltiazem 30mg bid and has been annually tested for urinary NMT, which is decreasing though still mildly elevated, plus imaging (MRI and/or PET-CT). Case 2 has been clinically asymptomatic with six-monthly chromogranin A determinations currently in the normal range, and annual imaging (MIBG scintigraphy, MRI and/or PET-CT). As both cases have bone metastatic disease, 5mg intravenous zoledronic acid was recently started. Sequencing of the coding exons and exon-intron boundaries of the SDHB gene found no mutations in P1, whereas a heterozygous frameshift deletion in exon 4 was found in P2 (c393delA). In P1, complementary Multiple Ligand-Binding Probe Amplification revealed a heterozygous deletion of SDHB exon 1. P1’s mother genetic screening was negative and the father refused testing. Six P2’s relatives were found to harbor the mutation, while 3 developed PGLs so far. Conclusion: Two cases of SDHB-related malignant PGL diagnosed at early ages were presented: one apparently sporadic (P1) and one familial (P2). Despite aggressive disease, with multiple disseminated bone metastases, a long-term survival has been achieved so far, with stable disease after high cumulative ^I131-MIBG doses and absence of significant adverse effects. Considering the rarity of the disease especially in children, these cases significantly add to the literature regarding the long-term course of malignant PGL and treatment options.

SUN-580 Pituitary Hyperplasia Secondary to Primary Hypothyroidism in Pediatrics: A Diagnosis Not to Be Forgotten

Background: Pathologic pituitary hyperplasia (PH) in Pediatrics may be observed in several clinical settings. In PH secondary to primary hypothyroidism the increased TRH levels, due to a long-standing hypothyroidism state and loss of negative thyroxin feedback, causes thyrotroph and lactotroph cells hypertrophy, leading to an enlarged pituitary gland. Herein we report on two pediatric patients presenting this condition. Patient 1: A 9 year-old female was referred due to severe short stature (height Z-score: -5 SDS), face myxedema and a suprasellar mass on MRI. She had a past of headache, fatigue and learning disabilities.  Laboratory evaluation showed anaemia and dyslipidemia (total cholesterol 282 mg/ dL, LDL 222 mg/dL); severe hypothyroidism: TSH 1,300 IU/L (NR 0.27-4.2), fT4 0.14 ng/dL (NR 0.93-1.7), negative thyroid antibodies TgAb 0.9 mcg/L (NR <4); and hyperprolactinemia (PRL: 110 ng/mL; NR 4.79-23.3). Her bone age was delayed (2,6 yr).  Pituitary MRI revealed a 19×16×12-mm mass pushing the optic chiasm. Thyroid ultrasound revealed a diminished gland. After fourteen months on LT4 therapy, she presented catch up growth (height Z-score: -3,8 SDS); and improvement in school duties. Lab evaluation showed improvement on thyroid function (fT4 0.89 ng/dL, TSH 1.57 IU/L), PRL (18.25 ng/mL) and lipids (total cholesterol 151 mg/ dL, LDL 83 mg/dL). A follow up pituitary MRI evidenced a normal-sized pituitary gland inside a still enlarged sella. Patient 2: A 19 year-old female was referred due to severe short stature (height Z-score: -4.61 SDS), myxedema, madarosis, and delayed puberty (Tanner B2PH1). Neurological complaints were absent, except for a mild slowing of the speech. Bone age was delayed (10 yrs). Her labs showed a severe primary autoimune hypothyroidism: TSH 606.60 IU/L, fT4 < 0.023 ng/dL, anti-TPO 85.8 IU/mL (NR < 4); and a mildly elevated PRL 67.59 ng/mL. Thyroid ultrasound revealed a small gland volume with heterogeneous texture. MRI evidenced a pituitary macroadenoma measuring 11x9x8 mm. After eight months on LT4 therapy, her thyroid function (fT4 1.04ng/dL, TSH 1.48 IU/L) and PRL (11.73 ng/mL) were in the normal range. A follow up MRI revealed a normal-sized pituitary gland. Conclusion: Evaluation of the hypothalamic-pituitary axis must always be taken into account when investigating pituitary masses, since MRI alone is unable to reliably differentiate the underlying condition. In both reported cases, hormonal profile was unequivocal, unmasking the diagnosis of pituitary hyperplasia secondary to primary hypothyroidism. A specialized and integrated approach is essential to adequately define treatment and prevent unnecessary intervention.

Clinical and pathological aspects of gossypiboma in a dog: case report

ABSTRACT A female dog was treated at the Veterinary Hospital Governador Laudo Natel for symptomscaused by an intra-abdominal gossypiboma (gossypium: cotton; boma: place of hiding). Showing high morbidity and mortality, the gossypiboma is a granulomatous reaction that is formed in response to exposure to a textile matrix. The objective of this report is to describe the clinical and pathological findings of an intra-abdominal gossypiboma in a female dog. This patient arrived at urgent care showing increased abdominal volume, pain, and cachexia. Ultrasonography showed a regular contour formation that could not be completely delimited. The patient underwent exploratory laparotomy and died in the postoperative period. The gossypiboma had a smooth, firm, and purple-gray exterior surface. Microscopy revealed a severe reaction of desmoplasia around the necrotic region, residual textile material, and adipose tissue. Negligence by veterinarians leading to this condition can result in patients’ death as well as causing psychological damage to owners.

Serological Survey of Rabies Virus Infection among Bats in Brazil

Rabies is a disease caused by a virus belonging to the family Rhabdoviridae, genus Lyssavirus (RABV), and is characterized as a progressive and acute encephalitis that presents high lethality. Between 2002 and 2012, 2149 wild animals were found positive for RABV in Brazil where 79% were associated with the aerial cycle of the disease. As part of the active surveillance of rabies in Brazil, the objective of this study was to investigate the presence of RABV infection in bats captured in two different regions of Brazil. Bat specimens were collected in (i) the metropolitan region of Rio de Janeiro city, (ii) Igrapiúna Municipality, Bahia State, and (iii) Serra do Tabuleiro State Park (PEST) in Santa Catarina State. Forty-four bats from the two first areas were tested for RABV at Institute Jorge Vaitsman (IJV), reference laboratory for rabies in Rio de Janeiro State. Of the individuals captured and sent for the diagnosis of rabies, a total of 15 were identified as being hematophagous, all of them belonging to the species Desmodus rotundus. Twenty-four individuals were considered as frugivorous, four as insectivores and one individual (Lonchophylla peracchii) identified as having a pollen/nectar feeding habit. All specimen sent to RABV diagnosis presented negative results. Considering the active surveillance for RABV in Brazil, studies of fauna survey with serological characterization are important in the strengthening of epidemiological surveillance and protection of human life.

Influence of Sub-Inhibitory Concentrations of Antimicrobial Agents on Biofilm Formation in Indwelling Medical Devices

Biofilms of Staphylococcus epidermidis and Candida spp. are two of the most frequent factors of infections associated with the use of indwelling medical devices. Several strategies have been proposed and/or developed to prevent infection. The aim of this study was to compare the effect of sub-inhibitory concentrations of anti-microbial agents on biofilm formation.

Biofilms of three strains of S. epidermidis and two of both Candida albicans and Candida dubliniensis were formed in the presence of three antibiotics and two antifungal agents respectively. Based on the control samples, the percentage of biofilm formation inhibition by the different agents was determined and compared.

The results showed that the influence of the antibacterial and antifungal agents tested is strain dependent, with the effect of the different agents also varying among strains, even though they have the same mechanism of action.

Detection of latent infections caused by Colletotrichum sp. in olive fruit

AIMS

To set up a practical method to detect latent infections of Colletotrichum sp., the causal agent of olive anthracnose, on olives before the onset of disease symptoms.

METHODS AND RESULTS

Freezing, sodium hydroxide (NaOH), ethanol and ethylene treatments were evaluated to detect latent infections on inoculated and naturally infected olive fruit by Colletotrichum sp. as non-hazardous alternatives to paraquat. Treatments were conducted using fruit of cultivars Arbequina and Hojiblanca. The disease incidence and T₅₀ were calculated. Dipping in NaOH 0·05% solution and the paraquat method were the most effective treatments on both inoculated and naturally infected fruit, although the value of T₅₀ was lower for the NaOH method than for the paraquat method in one of the experiments. Subsequently, the dipping time in NaOH 0·05% was evaluated. Longer dipping times in NaOH 0·05% were better than shorter ones in cultivar Arbequina, with 72 h being the most effective in cultivar Hojiblanca.

CONCLUSIONS

NaOH solution is a practical method to detect latent infections of Colletotrichum sp. on immature olive fruit.

SIGNIFICANCE AND IMPACT OF THE STUDY

This study is relevant because we set up a viable, non-hazardous alternative to paraquat to detect latent infections of Colletotrichum sp. using NaOH. The use of NaOH is a simple and eco-friendly tool that allows the determination of the level of latent infections by Colletotrichum in olives. Therefore, our method will be useful in decision-making processes for disease management before the appearance of the first visible symptoms.

First record of Cynoscion regalis (Pisces, Sciaenidae) in Portuguese continental waters

The occurrence of Cynoscion regalis in Portuguese continental waters is reported for the first time, with six specimens collected in 2015 from three areas: Tagus Estuary, Sado Estuary and Praia da Vieira (central-west coast). Analyses of morphometric and meristic characteristics confirmed all six specimens as C. regalis; further validation was obtained by sequencing a 675 bp region of the mitochondrial cytochrome c oxidase I gene. These records constitute a range extension of C. regalis into the southern north-east Atlantic Ocean.

Epitelização de enxertos cutâneos em feridas recentes de coelhos tratados com membrana amniótica canina e/ou laserterapia

RESUMO A enxertia cutânea é uma técnica cirúrgica simples e bastante útil para o reparo de feridas, principalmente aquelas onde existe dificuldade da aplicação do fechamento primário ou de outras técnicas reconstrutivas. Entretanto, para a sobrevivência do enxerto, é necessário que o leito da ferida esteja saudável e com presença de tecido de granulação exuberante. O objetivo do presente trabalho foi avaliar a aplicação da membrana amniótica e da laserterapia como potenciais estimulantes da cicatrização em enxertos aplicados em feridas sem tecido de granulação. Foram utilizados 42 coelhos, divididos em quatro grupos: grupo controle (GC), grupo membrana (GM), grupo laser (GL) e grupo membrana e laser (GML), submetidos a avaliações macro e microscópicas. Na avaliação macroscópica, foi possível notar que os pacientes dos grupos nos quais a membrana amniótica foi utilizada (GM e GML) apresentaram evidências associadas à acentuada reação inflamatória, à falha de integração do enxerto e à consequente necrose dele. Já os pacientes do GL apresentaram melhor aspecto do enxerto no último dia de avaliação. Na análise microscópica, observou-se intensa integração do enxerto à derme, reepitelização acentuada e escassas células inflamatórias no local do enxerto no GL. O contrário foi observado nos pacientes do GM e GML, nos quais aparentemente houve rejeição da membrana. A formação de colágeno não se correlacionou com outros fatores, como inflamação e necrose, em nenhum dos grupos de tratamento. Dessa forma, é possível afirmar que a laserterapia mostrou ser efetiva, contribuindo para o processo cicatricial e a integração do enxerto. Já a membrana amniótica canina não deve ser utilizada para esse fim, pois provoca intensa reação inflamatória, além de impedir a nutrição do enxerto.

A New Technique for Preserving the Form of Artificially Inflated Endophalli of Bees

We present a simple technique for keeping the form of artificially expanded endophalli in bees (Hymenoptera). Endophalli were inflated using the introduction of low melting-point agarose from a syringe inserted in the anterior opening of the metasoma. Under refrigeration, the endophalli kept their expanded shape for up to three days allowing the description of structure, morphometric analyses, and examination of the external sculpturing of the cuticle under scanning electron microscope. The technique provides new possibilities for the study of functional morphology, sexual selection, and reconstruction of bee phylogeny.

Note. Colonisation of Bench Cover Materials by Salmonella typhimurium

Due to the increasing requirements of food safety, it is of utmost importance to know the mechanisms that can determine the occurrence of the phenomenon commonly assigned by cross contamination, which can be expressed by the transference of harmful substances or microorganisms to the human food chain. This is particularly susceptible during food preparation, because it can occur by the transference of the pathogen microorganisms from food to the surfaces where they had been prepared, and from there to foods initially not contaminated, therefore initiating the cycle. This study attempted to investigate the colonisation by Salmonella typhimurium ATCC 13311 of marble and granite, two materials commonly used as bench covers in kitchens of many countries. These materials were selected because there is a lack of studies in the literature about their ability for bacterial colonisation. In addition, the colonisation of stainless steel (SS) 304, a material usually studied, was also analysed in terms of comparison. Surface hydrophobicity and roughness were determined in order to explain the differences in the extent of adhesion. The results showed that SS was the material with a greater extent of colonisation by S. typhimurium, followed by marble and, almost to the same extent, by granite. S. typhimurium adheres to a greater extent to the most hydrophobic material and to the material with roughest surface.

Abstract P164: The Role of the Adrenoreceptors Beta 3 on Metabolic Syndrome Induced by Fructose

The aim of this study was to evaluate the role of the adrenoreceptor beta 3 (ARβ3) in the cardiovascular function on Metabolic Syndrome (MS) induced by fructose overload. Male mice after weaning (8-10g) were divided into 4 groups (n=7/group): FVB Control (C) and ARβ3 Knockout Control (Kβ3C), with free access to food and water for 8 weeks; FVB fructose (F) and ARβ3 Knockout fructose (Kβ3F), with free access to food and fructose added to the drinking water (10%) for 8 weeks. At the end of the protocol, intraperitoneal glucose tolerance test was performed. Triglycerides and HDL fractions were evaluated by colorimetric methods. The animals were submitted to catheterization of carotid artery. This catheter was connected to a transducer and continuous signals of blood pressure (BP) was recorded. The variability of the resultant signal was evaluated in frequency domain. Visceral fat deposits were collected, weighted and normalized as fat (mg)/body weight (g). Results: fructose increased the fasting glycemia in the knockout group (Kβ3C=93±3 vs. Kβ3F=122±7 mg/dL) and decreased the glucose tolerance in both fructose groups. Fructose increased the triglycerides and decreased HDL cholesterol. The uric acid increased in the knockout animals. There was an increase on visceral fat deposits only in FVB animals (C=10±2 vs. F=16±1 mg/g), as well as on blood pressure (C=123±4 vs. 136±2 mmHg) There was an increase on blood pressure variability for all experimental groups compared to Control (C=10.7±1 vs. F=36±11; Kβ3C=50±7; Kβ3F=24±4 mmHg 2 ) as well as on peripheral sympathetic modulation (C=3.3±0.4 vs. F=8.1±0.1; Kβ3C=22.9±3; Kβ3F=9.2±2 mmHg 2 ). Furthermore, Kβ3F showed a decrease on blood pressure variability and peripheral sympathetic modulation. Our data suggest that the hypertension induced by fructose is related with adiposity. Moreover, the blood pressure variability and its sympathetic modulation are dependent of the ARB3. The association between fructose and ARβ3 knockout leads to the loss of the sympathetic modulation.
