Abstract
Streptococcus uberis is a major cause of environmental mastitis in many regions, and it is associated with clinical and subclinical infections. Although the main source of infection is the environment, reports of strains with a contagious profile have been described. Dot blot hybridization analysis allows the rapid identification of S. uberis population structures within and between herds, and it helps to identify strain diversity as well as possible clonal lineages that directly affect the control of bovine mastitis caused by this pathogen. The aim of this study was to evaluate the diversity of S. uberis isolates obtained from clinical (n = 22) and subclinical (n = 22) cases of mastitis in dairy herds (n = 13) in Brazil over a period of 12 mo. We submitted 44 S. uberis isolates to dot blot hybridization followed by automatic data analysis. We identified 8 different hybridization patterns using genetic markers associated with virulence factors and taxonomy, indicating diversity of S. uberis within the population and suggesting environmental transmission. However, the evidence of identical dot blot patterns in different mammary quarters from the same animal also suggested local contagious transmission. Of the virulence genes evaluated, we found a high prevalence of the genes sua, pauA, and gapC, highlighting the importance of these virulence factors for the adhesion, invasion, and multiplication of S. uberis in subclinical and clinical intramammary infections.

Abstract
UNLABELLED Using genetic, clinical, biochemical, and radiographic assessment and bioinformatic approaches, we present an unusual case of adult HPP caused by a novel de novo heterozygous nonsense mutation in the alkaline phosphatase (ALPL). INTRODUCTION Hypophosphatasia (HPP) is caused by genetic alterations of the ALPL gene, encoding the tissue-nonspecific isozyme of alkaline phosphatase (TNSALP). Here, the purpose was to perform clinical and molecular investigation in a 36-year-old Caucasian woman suspected to present adult HPP. METHODS Medical and dental histories were obtained for the proposita and family members, including biochemical, radiographic, and dental assessments. ALPL mutational analysis was performed by the Sanger sequencing method, and the functional impact prediction of the identified mutations was assessed by bioinformatic methods. RESULTS We identified a novel heterozygous nonsense mutation in the ALPL gene (NM_000478.6:c.768G>A; W[TGG]>*[TGA]) associated with spontaneous vertebral fracture, severe back pain, musculoskeletal pain, low bone density, and short-rooted permanent teeth loss. Functional prediction analysis revealed that the Trp256Ter mutation led to a complete loss of TNSALP crown domain and extensive loss of other functional domains (calcium-binding domain, active site vicinity, and zinc-binding site) and over 60% loss of homodimer interface residues, suggesting that the mutant TNSALP molecules are nonfunctional and form unstable homodimers. Genotyping of the ALPL in the proposita's parents, sister, and niece revealed that in this case, HPP occurred due to a de novo mutation. CONCLUSION The present study describes a novel genotype-phenotype and structure-function relationship for HPP, contributing to a better molecular comprehension of HPP etiology and pathophysiology.

Abstract
Introduction
Immunization is a human right, being considered an action of the most successful and cost-effective in public health. In Brazil, it is an action that is linked to primary health care, In Brazil, the National Immunization Program (PNI), created in 1973, is recognized as a world reference of public health policy, as it offers all vaccines recommended by the World Organization health care in its national vaccination calendar.
Objective
Spatial analysis of vaccination coverage of children aged 0 to 11 months in Paraíba in 2016.
Methods
Cross-sectional study, with information on doses applied to children under 1 year of age obtained at the PNI, by municipality of Paraíba. Live birth data from the Live Birth information system (SINASC). Descriptive analysis, chi-square test, spatial analysis.
Results
In Paraíba, 54.3% of the municipalities had adequate vaccination coverage, for BCG we have 68%, Hepatitis B (34.5%), Hib and DTP (35%), Polio (29.6%), pneumococcal (46.6%) and meningococcal (42.6%). The sertão paraibano is the mesoregion with the largest number of municipalities in the state with adequate vaccination coverage (p < 0.01), the paraiba forest is the region with the highest number of municipalities with very low coverage (p < 0.01).
Conclusions
Thus, Paraíba does not present a homogeneous vaccination coverage, not having 'herd immunity'. This fact leaves the state vulnerable to the return of immunopreventable diseases and thus at risk of raising infant morbidity and mortality, constituting an important public health problem.
Key messages
Immunization is a human right, being considered an action of the most successful and cost-effective in public health. Paraíba does not present a homogeneous vaccination coverage, not having 'herd immunity'.

Abstract
Introduction
Breast cancer is a worldwide public health issue. The distribution of the disease presents different behavior depending on the region. In Brazil, for the triennium 2020/2022, approximately 66.28 per 100,000 new cases are expected each year, with the highest incidence in the southeast region 81.06 per 100,000. The region of this study has high mortality rates from the disease and several environmental contaminants classified as carcinogenic.
Methodology
A spatial and temporal ecological study of the breast cancer distribution in the municipalities of the Baixada Santista with secondary data from 2000 to 2011, in women 20 years or older. The cancer data of 3,233 cases were provided by the Oncocentro Foundation of São Paulo, of the contaminated areas were provided by the Technology of Environmental Sanitation Company, and the population at risk were provided by the State Data Analysis System. Standardized coefficients of annual breast cancer rates for each municipality, to characterize exposure, an indicator of contamination per municipality was constructed. Pearson's correlation was used to analyze breast cancer rates and environmental contamination rates. Cartographic sequencing to analyze the distribution and spatiotemporal evolution of outcome and exposure. Trend analysis used linear regression.
Results
The municipality of Santos presented the highest rates of the disease. Pearson's correlation was positive, with r = 0.7 (p = 0.036). Spatially, the most contaminated areas had the highest rates of breast cancer, except in one municipality. Trend analysis in eight of the nine municipalities in the region signaled an increased number of cases.
Conclusions
The study confirmed that environmental contamination interferes with the distribution of breast cancer and the temporal trend signaled an increase in the disease in eight of the nine municipalities in the region.
Key messages
Environmental Contamination. Breast Cancer.

Abstract
Abstract
Introduction
The Região Metropolitana da Baixada Santista (RMBS) is considered as a region with the worst maternal and child mortality rates in the state of São Paulo, Brazil. Besides this, RMBS has the worst rates of environmental contamination. High-Risk Pregnancy is one of the factors that lead to a higher chance of morbidity and mortality of the mother and fetus binomial.
Objective
Evaluate the relationship between exposure to environmental contaminants and high-risk pregnancy.
Methodology
Case-control study, using a probabilistic sample composed of 402 pregnant women divided into with and without high-risk pregnancy. The instrument used was a self-administered questionnaire and secondary data on contaminated areas obtained from the Environmental Company of the State of São Paulo. Descriptive analysis, Chi-square test, univariate and multiple logistic regression analysis were performed. The participants were also georeferenced by place of residence.
Results
It was observed an association, by chi-square test between high-risk pregnancy and age over 35 years (p < 0.05), use of insecticide (p < 0.001), consumption of foods packed in plastics (p = 0.050) and manipulation with oil paint (p = 0.002). The final multiple logistic regression model demonstrated that those who live in contaminated areas are 2 times more likely to have a risk pregnancy (OR = 1.993; 95%CI: 1.02; 3.90), as well as identified as jointly important risk factors for pregnancy: working in health services (OR = 3.97 (95%CI: 1.00; 16.09)), use of insecticide (OR = 3.45 (95%CI: 1.66; 7.16)) and use of oil paint (OR = 6.96 (95%CI: 1.38; 35.09)).
Conclusions
Environmental contaminants play an important role in pregnancy, and mitigating measures are needed to improve the environment and reduce high-risk pregnancy in RMBS.
Key messages
Exposure to the environmental contaminants is an important rik factor in the pregnancy. The Região Metropolitana da Baixada Santista (RMBS) is considered as a region with the worst maternal and child mortality rates in the state of São Paulo, Brazil.

Abstract
Chédiak-Higashi syndrome (CHS), a rare autosomal recessive disorder caused by mutations in the lysosomal trafficking regulator gene (LYST), is associated with aggressive periodontitis. It is suggested that LYST mutations affect the toll-like receptor (TLR)-mediated immunoinflammatory response, leading to frequent infections. This study sought to determine the periodontal status of patients with classic (severe) and atypical (milder) forms of CHS and the immunoregulatory functions of gingival fibroblasts in CHS patients. In contrast to aged-matched healthy controls, atypical (n = 4) and classic (n = 3) CHS patients presented with mild chronic periodontitis with no evidence of gingival ulceration, severe tooth mobility, or premature exfoliation of teeth. As a standard of care, all classic CHS patients had undergone bone marrow transplantation (BMT). Primary gingival fibroblasts obtained from atypical and BMT classic CHS patients displayed higher protein expression of TLR-2 (1.81-fold and 1.56-fold, respectively) and decreased expression of TLR-4 (-2.5-fold and -3.85-fold, respectively) at baseline when compared with healthy control gingival fibroblasts. When challenged with whole bacterial extract of Fusobacterium nucleatum, both atypical and classic CHS gingival fibroblasts failed to up-regulate TLR-2 and TLR-4 expression when compared with their respective untreated groups and control cells. Cytokine multiplex analysis following F. nucleatum challenge showed that atypical CHS gingival fibroblasts featured significantly increased cytokine expression (interleukin [IL]-2, IL-4, IL-5, IL-6, IL-10, IL-12, interferon-γ, tumor necrosis factor-α), whereas classic CHS cells featured similar/decreased cytokine expression when compared with treated control cells. Collectively, these results suggest that LYST mutations in CHS patients affect TLR-2 and TLR-4 expression/function, leading to dysregulated immunoinflammatory response, which in turn may influence the periodontal phenotype noted in CHS patients. Furthermore, our results suggest that atypical CHS patients and classic CHS patients who undergo BMT early in life are less susceptible to aggressive periodontitis and that hematopoietic cells play a critical role in mitigating the risk of aggressive periodontitis in CHS. Knowledge Transfer Statement: Results from this study can be used to create awareness among clinicians and researchers that not all CHS patients exhibit historically reported aggressive periodontitis, especially if they have atypical CHS disease or have received bone marrow transplantation. LYST mutations in CHS patients may affect TLR-2 and TLR-4 expression/function leading to dysregulated immunoinflammatory response, which in turn may influence the periodontal phenotype noted in CHS patients.

Abstract
Poultry colibacillosis due to Avian Pathogenic Escherichia coli (APEC) is responsible for several extra-intestinal pathological conditions, leading to serious economic damage in poultry production. The most commonly associated pathologies are airsacculitis, colisepticemia, and cellulitis in broiler chickens, and salpingitis and peritonitis in broiler breeders. In this work a total of 66 strains isolated from dead broiler breeders affected with colibacillosis and 61 strains from healthy broilers were studied. Strains from broiler breeders were typified with serogroups O2, O18, and O78, which are mainly associated with disease. The serogroup O78 was the most prevalent (58%). All the strains were checked for the presence of 11 virulence genes: 1) arginine succinyltransferase A (astA); ii) E.coli hemeutilization protein A (chuA); iii) colicin V A/B (cvaA/B); iv) fimbriae mannose-binding type 1 (fimC); v) ferric yersiniabactin uptake A (fyuA); vi) iron-repressible high-molecular-weight proteins 2 (irp2); vii) increased serum survival (iss); viii) iron-uptake systems of E.coli D (iucD); ix) pielonefritis associated to pili C (papC); x) temperature sensitive haemaglutinin (tsh), and xi) vacuolating autotransporter toxin (vat), by Multiplex-PCR. The results showed that all genes are present in both commensal and pathogenic E. coli strains. The iron uptake-related genes and the serum survival gene were more prevalent among APEC. The adhesin genes, except tsh, and the toxin genes, except astA, were also more prevalent among APEC isolates. Except for astA and tsh, APEC strains harbored the majority of the virulence-associated genes studied and fimC was the most prevalent gene, detected in 96.97 and 88.52% of APEC and AFEC strains, respectively. Possession of more than one iron transport system seems to play an important role on APEC survival.

Abstract
BACKGROUND HLA alloimmunization is caused by sensitization events (SEs), such as transfusion, pregnancy, or previous organ transplantation, and the effects of particular SEs have not been thoroughly studied. Our aim was to evaluate how each SE affected HLA alloimmunization by considering Luminex assays. METHODS Sera from 722 kidney transplantation candidates were screened per protocol by means of Luminex assays to determine the presence of anti-HLA class I/II antibodies; positive sera underwent single-antigen assay to determine the presence of specific antibodies against HLA A, B, C, DR, DQ, DP loci (positivity if median fluorescence intensity values were >1,000). The effect of each SE was analyzed considering only patients exposed to 1 kind of sensitization. RESULTS In the 453 candidates with ≥1 SE, anti-HLA class I positivity rates were significantly higher in patients with previous transfusion (18.9%; P = .014), pregnancy (38.3%; P < .001) or transplant (75%; P < .001) compared with those with no SE (similar results for class II). The strength (median fluorescence intensity) of specific antibodies was significantly higher in patients with previous transplantation than in those with previous transfusion for HLA-A (8,017 vs 2,302; P = .02), HLA-B (7,765 vs 2,901; P = .018), and HLA-DR (9,835 vs 2,060; P = .003). Other anti-HLA antibody strengths were similar between patients with previous pregnancy or transplantation. CONCLUSIONS Presence of any SE analyzed was associated with a higher prevalence of anti-HLA antibodies for class I ± II compared with nonsensitized patients. Transplantation had the strongest immunization effect on both classes, followed by pregnancy and then transfusion.

Abstract
OBJECTIVES Typhoid fever (TF) occurs rarely in industrialized countries because of advances in health care and improvement of drinking water. Conversely, non-typhoid salmonellosis (NTS) remains widespread, because of food contamination or asymptomatic carriage. Non-typhoid salmonellosis can be severe when becoming invasive non-typhoid salmonellosis (iNTS). Although established prognostic indicators of the two pathologies are different, direct comparisons between iNTS and TF in the literature remain scarce. The purpose of this study was to analyse and compare demographic, clinical features and outcome of hospitalized patients with TF and iNTS. METHODS Demographic, clinical features and outcome were retrospectively analysed in a series of patients hospitalized between 2007 and 2012. RESULTS A total of 33 patients were enrolled, including 13 with established TF and 20 with iNTS. No differences between TF and iNTS patients were observed in incidence of fever, abdominal cramps, diarrhoea, headache, nausea and vomiting and duration of antibiotic therapy (≤ 7 days in both groups). Although the clinical outcome of TF patients was identical to that of iNTS patients, including incidence of complications, length of hospitalization and mortality (1/13 (7.7%) vs 2/20 (10%), P = 0.43), comorbidities were less frequent in the TF group than in the iNTS group (2/13 vs 15/20, P = 0.003). CONCLUSION The clinical profile and outcome of TF patients are similar to those with iNTS. Although comorbidities are more often associated with iNTS, the results of our study suggest that clinical management of these two diseases should remain similar.

Abstract
Na busca de material biológico alternativo para a realização de implantes, objetivou-se com o presente estudo avaliar comparativamente a implantação do peritônio de paca, uma nova opção de biomaterial, conservado em solução supersaturada de açúcar a 300% e conservado em glicerina a 98% na parede abdominal de ratos Wistar. Foram utilizados 60 ratos, machos, da linhagem Wistar, pesando entre 150 e 200 gramas, organizados nos seguintes grupos experimentais: grupo controle (GI), grupo peritônio conservado em solução supersaturada de açúcar a 300% (GII) e grupo peritônio conservado em glicerina a 98% (GIII), cada um com 20 animais. Os grupos GII e GIII receberam o enxerto de peritônio da paca conservado em solução de açúcar 300% e glicerina 98%, respectivamente, e o grupo GI não recebeu a membrana. Cinco ratos de cada grupo foram submetidos à eutanásia em quatro momentos distintos: sete, 15, 30 e 60 dias de pós-operatório para avaliações macroscópicas e microscópicas da interface implante-tecido nativo. Apesar de reações adversas observadas em 57,5% dos animais do grupo GII e GIII, em 95% dos animais desses grupos houve boa cicatrização da membrana. Na análise histológica, verificou-se a presença de grande infiltrado inflamatório nos períodos iniciais (sete e 15 dias) e grande presença de tecido conjuntivo nos momentos finais (30 e 60 dias). Concluiu-se que o peritônio da paca como membrana biológica conservado nos meios estudados pode ser utilizado com segurança na parede abdominal de ratos; ainda, que sua conservação em solução supersaturada de açúcar a 300% permitiu melhor maleabilidade no ato cirúrgico.

Abstract
Neste estudo foi implantado um retalho de biomembrana de látex natural em substituição a um fragmento da parede de estômago de coelhos albinos, raça Nova Zelândia, adultos, machos não castrados (n=12), com o intuito de avaliar o processo de reparação tecidual no que se refere à biocompatibilidade, à capacidade de reparação tecidual e a possíveis complicações. Aos 15, 30 e 60 dias de pós-operatório, os animais foram sacrificados, mediante o emprego de tiopental sódico (200mg kg-1), para posterior avaliação macroscópica e análise histopatológica da interface do implante com o tecido nativo. Macroscopicamente, aos 15, 30 e 60 dias de pós-operatório observou-se presença de aderências na face serosa. Aos 60 dias de pós-operatório, em todos os animais avaliados, a biomembrana não foi encontrada. Sob microscopia de luz, aos 15 e 30 dias, verificaram-se descontinuidade das camadas muscular e mucosa, presença de infiltrado inflamatório polimorfonuclear. Foram visualizados vasos sanguíneos e fibras musculares. Aos 60 dias, as camadas mucosa, muscular estavam completamente reconstituídas. O implante foi biocompatível e forneceu arcabouço para orientação e desenvolvimento das camadas teciduais do estômago, mediante processos de reparação, restabelecendo a estrutura do órgão.

Abstract
Erectile dysfunction is experienced by 50% of men with end-stage renal disease (ESRD) and uremia. The origin of this dysfunction is multifactorial. The aim of this study was to compare living donor versus cadaveric donor transplant recipients regarding male sexual function. Seventy-seven sexually active male kidney transplant recipients (44 from living donors; 33 from cadaveric donors) were randomly selected from our single-center prospective database of 2016 renal transplants. Epidemiological and clinical data were collected between June 2010 and June 2011. Male sexual function was evaluated with the International Index of Erectile Function questionnaire (IIEF-15). We assessed the prevalence of male sexual dysfunction according to established cutoff points for each of the IIEF-15 domains. Mann-Whitney and Pearson's chi- square statistical tests were used to compare continuous and categorical variables, respectively. The median age at the time of completion of the questionnaires was 43 and 51 years (P = .003) with median times from transplantation was of 36 and 42 months for living donor and cadaveric donor recipients, respectively (P = .31). Median durations of ESRD before surgery were 17.5 and 57 months for living donor and cadaveric donor recipients, respectively (P < .001). Living donor and cadaveric donor recipients had median creatinine clearance values of 55 and 57 mL/min, respectively (P = .44). Median time after renal transplantation for first sexual intercourse was 1 and 2 months for living donor and cadaveric donor recipients, respectively (P = .35). Median body mass indices for living donor and cadaveric donor recipients were 24.8 and 24, respectively (P = .31). Regarding sexual function domains, there were significant differences only for intercourse satisfaction. In our cohort, living donor recipients tended to be younger, have shorter time of ESRD, and less incidence of hypertension or diabetes mellitus but with greater tobacco use. In conclusion, living donor transplantation exerted a favorable impact on sexual function.

Abstract
BACKGROUND Poor oral health has been related with cardiovascular diseases. Specifically, periodontitis has been implicated in the pathogenesis of atherosclerosis. Our aim was to evaluate the relationship between the degree of carotid atherosclerosis and severity of periodontitis in a patient cohort. METHODS Fifty adult patients receiving carotid duplex scans in a cerebral hemodynamics lab were included in the study. Ultrasound protocol included measurement of carotid intima-media thickness (IMT), which is a marker of atherosclerosis, and characterization of any atherosclerotic plaques in the cervical common and internal carotid arteries. Patients were divided into two main groups: the test group had IMT ≥ 1 mm or the presence of any carotid atherosclerotic plaque, and the control group had IMT < 1 mm and absence of atherosclerotic plaques. Periodontal evaluation was performed in all the teeth and characterized according to the clinical attachment level, which between 1 mm and 2 mm was classified as slight, 3 mm and 4 mm as moderate and ≥5 mm as severe. RESULTS The control group included 15 (30%), while the test group included 35 (70%) subjects. The most common diagnosis was severe periodontitis (40%); moderate and slight periodontitis were also frequent occurrences (32% and 28%, respectively). In the control group, 53.3% had slight, 33.3% had moderate and 13.3% had severe periodontitis. In the test group, those percentages were respectively 22.2%, 44.4% and 33.3%. Patients with atheroma plaque had the highest percentage of severe periodontitis (70.6%). More severe periodontitis was related to atherosclerosis (P = 0.007). CONCLUSION This study showed an association between periodontitis severity and carotid atherosclerosis, suggesting that periodontal disease might be a risk indicator for atherosclerotic disease.

Abstract
Descreveram-se a morfologia, morfometria e ultraestrutura de segmentos das porções torácica e abdominal da aorta de quatro pacas (Cuniculus paca) adultas. Os segmentos aórticos foram analisados à microscopia de luz e à microscopia eletrônica de varredura. Mensuraram-se as espessuras do complexo formado pelas túnicas íntima e média, além da túnica adventícia. Os valores referentes à espessura do complexo formado pelas túnicas íntima e média da aorta torácica cranial foram significativamente maiores (média: 702,19µm) que os valores de outros segmentos aórticos analisados (médias: 354,18µm; 243,55µm). As camadas das paredes do vaso apresentaram variações entre si quanto à estrutura e espessura, supostamente em razão de adaptação à exigência funcional.

Abstract
BACKGROUND Peristomal skin problems are common and are treated by a variety of health professionals. Clear and consistent communication among these professionals is therefore particularly important. The Ostomy Skin Tool (OST) is a new assessment instrument for the extent and severity of peristomal skin conditions. Formal tests of reliability and validity are necessary for its use in clinical practice, research, and education. OBJECTIVES To estimate inter- and intra nurse assessment variability of the OST and validity by comparison to a 'gold standard' (GS) defined by an expert panel. METHODS Thirty photographs of peristomal skin were presented twice to 20 ostomy care nurses--10 from Denmark (DK) and 10 from Spain (ES)--to determine intra- and inter nurse assessment variability. The same photographs were presented to an international group of experts (dermatologist and ostomy care nurses), to establish a GS for comparison and validation of the results. RESULTS A high intra-nurse assessment agreement, κ=0·84, was found with no differences in the intra-nurse assessments from the two groups of nurses (DK and ES). The inter-nurse assessment agreement was 'moderate to good', κ=0·54, with the agreement between the experts higher, κ=0·70. A high correlation between the scores from the nurses and the GS were seen in the lower part of the two scales [Discoloration, Erosion, Tissue overgrowth (DET) score<7)]. CONCLUSION The study supported the validity of the OST. It is suggested that a categorical scale can be used to illustrate the severity of the DET scores.

Abstract
Descreveu-se a morfologia do útero de cutias nulíparas e não nulíparas por meio de ovariossalpingoisterectomia. A análise macroscópica do útero foi realizada in loco e na peça retirada. Segmentos das porções proximal, média e distal do órgão foram colhidas, fixadas e preparadas histologicamente, sendo as amostras analisadas à microscopia de luz, e realizada a histomorfometria das camadas uterinas. Topograficamente, o útero localiza-se na região sublombar, caudalmente aos rins, em continuação aos ovários e às tubas uterinas, estendendo-se até à entrada da pelve, onde se posiciona dorsalmente à bexiga. Caracteriza-se como do tipo duplo, embora culmine em apenas um óstio cervical externo. Microscopicamente, a mucosa uterina é formada por variações do epitélio, de cilíndrico a pseudoestratificado, que se apoia em tecido conjuntivo frouxo, onde se observam glândulas endometriais revestidas por epitélio cilíndrico, além da presença de vasos sanguíneos. A camada muscular subdivide-se em interna ou submucosa, média ou vascular e externa ou subserosa. A camada serosa é composta por tecido conjuntivo e mesotélio. Na histomorfometria, verificou-se que a espessura uterina total e a espessura da camada mucosa, em média, foram maiores nas fêmeas não nulíparas.

Abstract
Rett syndrome is a neurodevelopmental disorder caused by mutations in the methyl-CpG binding protein 2 gene (MECP2). Several neural systems are affected in Rett, resulting in an autonomic dysfunction, a movement disorder with characteristic loss of locomotor abilities and profound cognitive impairments. A deregulation of monoamines has been detected in the brain and cerebrospinal fluid of both Rett patients and a Rett syndrome murine model, the Mecp2 knock-out mouse. Our goal was to characterize the onset and progression of motor dysfunction in Mecp2(tm1.1Bird) knock-out mice and the possible neurochemical alterations in different brain regions potentially playing a role in Rett-like pathophysiology, at two different time-points, at weaning (3 weeks old) and in young adults when overt symptoms are observed (8 weeks old). Our results revealed significant age- and region-dependent impairments in these modulatory neurotransmitter systems that correspond well with the motor phenotype observed in these mice. At 3 weeks of age, male Mecp2 knock-out mice exhibited ataxia and delayed motor initiation. At this stage, noradrenergic and serotonergic transmission was mainly altered in the prefrontal and motor cortices, whereas during disease progression the neurochemical changes were also observed in hippocampus and cerebellum. Our data suggest that the deregulation of norepinephrine and serotonin systems in brain regions that participate in motor control are involved in the pathophysiology of Rett syndrome motor phenotypes. Moreover, we highlight the contribution of cortical regions along with the brainstem to be in the origin of the pathology and the role of hippocampus and cerebellum in the progression of the disease rather than in its establishment.
