Abstract
INTRODUCTION Genomic variants of the human papillomavirus type 16 (HPV16) are thought to play differential roles in the susceptibility to head and neck squamous cell carcinomas (HNSCC) and its biological behaviour. This study aimed to establish the prevalence of HPV16 variants in an HNSCC cohort and associate them with clinical pathological characteristics and patient survival. METHODS We retrieved samples and clinical data from 68 HNSCC patients. DNA samples were available from tumour biopsy at the time of the primary diagnosis. Targeted next-generation sequencing was used to obtain whole-genome sequences, and variants were established based on phylogenetic classification. RESULTS 74% of samples clustered in lineage A, 5.7% in lineage B, 2.9% in lineage C, and 17.1% in lineage D. Comparative genome analysis revealed 243 single nucleotide variations. Of these, one hundred were previously reported, according to our systematic review. No significant associations with clinical pathological variables or patient survival were observed. The E6 amino acid variations E31G, L83V, and D25E and E7 N29S, associated with cervical cancer, were not observed, except for N29S in a single patient. CONCLUSION These results provide a comprehensive genomic map of HPV16 in HSNCC, highlighting tissue-specific characteristics which will help design tailored therapies for cancer patients.

Abstract
Introduction: Heart failure (HF) is a syndrome increasing worldwide, and literature shows
that the hospitalizations are associated with greater mortality rates. A
patient-centered method combined with optimized medical treatment and
palliative care may improve HF outcomes, and some advocate a multifaceted
approach to achieve a perfect management of chronic HF (CHF). Objective: The objective of this study was to present the study protocol of GENICA
project which aims to optimize the ambulatory approach of CHF patients, and
reduce their re-hospitalization, emergency readmission, and global death
rate. Design: Prospective cohort including patients referred to HF consultation and
collecting sociodemographic, clinical, and analytical variables among
others. The outcomes will be mortality, re-hospitalization, and emergency
readmission rates. The association between the independent variables and
outcomes will be assessed by logistic regression. Comparison between GENICA
patients and controls will be made by χ2 test. Significance at
p level of less than 0.05. Results: GENICA will offer a wide range of longitudinal data with evidence that will
influence future healthcare of CHF patients at an ambulatory basis. Discussion: GENICA will provide practical evidence of real HF patient’s profile and
develop workable decision algorithms, which will influence future ambulatory
care of CHF. HF patients will be safer at home and will keep stability for
longer periods, consuming less health resources and slow the progression of
the disease. Being a matched cohort, GENICA benefits from an accuracy
similar to that of randomized controlled trials, without the need to perform
a rigorous allocation of the intervention. Being prospective there’s no
problem about response bias. Conclusion: CHF should be approached with a multidisciplinary and multifaceted strategy
privileging the outpatient setting, including home monitoring, and GENICA is
the paramount protocol enabling this. GENICA may come to show health policy
makers that the asset is not to divide and rule, but to converge strategies,
therapies, and knowledge.

Abstract
INTRODUCTION Heart failure (HF) represents a huge financial and economic burden worldwide. Some authors advocate that remote monitoring should be implemented to improve HF management, but given its increasing incidence, as well as its morbidity and mortality, a question still remains: are we monitoring it properly? There is no shortage of literature on home monitoring devices, however, most of them are designed to monitor an unsuitable array of variables and, to the best of our knowledge, there are no large randomized studies about their impact on morbidity/mortality of HF patients. OBJECTIVE Description of a novel monitoring device. METHODS As a solution, we designed MONITORIA (MOnitoring NonInvasively To Overcome mortality Rates of heart Insufficiency on Ambulatory). RESULTS This is a multimodal device that will provide real time monitoring of vital, electrophysiological, hemodynamic and chemical signs, transthoracic impedance, and physical activity levels. The device is meant to perform continuous analysis and transmission of all data. Significant alterations in a patient's variable will alert the attending physician and, in case of potentially life-threatening situations, the national emergency medical system. The MONITORIA device will, also, have a function that sends shocks or functions as a pacemaker to treat certain arrhythmias/blockades. This function can be activated the very first time the patient utilizes it, based on their risk of sudden cardiac death. DISCUSSION/CONCLUSIONS MONITORIA is a promising device mostly because it is included in a follow-up program that takes into account a multi-perspective feature of HF development and is based on the real world patient, adapting innovations not to the disease but rather to the patients.

Abstract
Heart failure (HF) is a multifactorial chronic syndrome with progressive increasing incidence causing a huge financial burden worldwide. Remote monitoring should, in theory, improve HF management, but given increasing morbidity and mortality, a question remains: are we monitoring it properly? Device-based home monitoring enables objective and continuous measurement of vital variables and non-invasive devices should be first choice for elderly patients. There is no shortage of literature on the subject, however, most studies were designed to monitor a single variable or class of variables that were not properly assembled and, to the best of our knowledge, there are no large randomized studies about their impact on HF patient management. To overcome this problem, we carefully selected the most critical possible HF decompensating factors to design MONITORIA, a non-invasive device for comprehensive HF home monitoring. MONITORIA stands for MOnitoring Non-Invasively To Overcome mortality Rates of heart Insufficiency on Ambulatory, and in this paper, which is part I of a series of three articles, we discuss the theoretical basis for its design. MONITORIA and its inherent follow-up strategy will optimize HF patient care as it is a promising device, which will essentially adapt innovation not to the disease but rather to the patients.

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
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
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

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
Due to unfavorable conditions for survival and multiplication of Mycobacterium tuberculosis, muscle and soft tissue involvement is probably the rarest form of presentation of musculoskeletal tuberculosis, particularly without a clinically or radiologically apparent primary focus. As in other extrapulmonary forms of tuberculosis, its relative incidence is higher among immunocompromised patients. A progressive swelling is the most common complaint at presentation, which is otherwise mild and nonspecific. We present a case of multifocal (seven) subcutaneous and muscular tuberculous abscesses in a 29-year-old Indian patient who had no apparent underlying risk factors, nor any other organ involvement. Provisional diagnosis was initially made upon Mycobacterium tuberculosis complex nucleic acid detection in an aspirate of one of the collections and later confirmed by a positive culture on Lowenstein-Jensen medium. Two abscesses required aspiration and two others drained spontaneously. The patient responded well to nine months of anti-tuberculous therapy. An extensive review of the literature was made.

Abstract
INTRODUCTION Respiratory syncytial virus (RSV) is associated with substantial morbidity and mortality since it is a predominant viral agent causing respiratory tract infections in infants, young children and the elderly. Considering the availability of the RSV vaccines in the coming years, molecular understanding in RSV is necessary. OBJECTIVE The objective of the present study was to describe RSV epidemiology and genotype variability in Portugal during the 2014/15-2017/18 period. MATERIAL AND METHODS Epidemiological data and RSV-positive samples from patients with a respiratory infection were collected through the non-sentinel and sentinel influenza surveillance system (ISS). RSV detection, subtyping in A and B, and sequencing of the second hypervariable region (HVR2) of G gene were performed by molecular methods. Phylogenetic trees were generated using the Neighbor-Joining method and p-distance model on MEGA 7.0. RESULTS RSV prevalence varied between the sentinel (2.5%, 97/3891) and the non-sentinel ISS (20.7%, 3138/16779), being higher (P < 0.0001) among children aged <5 years. Bronchiolitis (62.9%, 183/291) and influenza-like illness (24.6%, 14/57) were associated (P < 0.0001) with RSV laboratory confirmation among children aged <6 months and adults ≥65 years, respectively. The HVR2 was sequenced for 562 samples. RSV-A (46.4%, 261/562) and RSV-B (53.6%, 301/562) strains clustered mainly to ON1 (89.2%, 233/261) and BA9 (92%, 277/301) genotypes, respectively, although NA1 and BA10 were also present until 2015/2016. CONCLUSION The sequence and phylogenetic analysis reflected the relatively high diversity of Portuguese RSV strains. BA9 and ON1 genotypes, which have been circulating in Portugal since 2010/2011 and 2011/2012 respectively, predominated during the whole study period.

Abstract
This work targeted the energy recovery from food waste (FW), aiming at the implementation of a potentially participative process of FW conditioning before the non-sterile biological conversion to hydrogen (H2). Food waste conversion was initially performed under sterile conditions, achieving a maximum H2 productivity of 249.5 ± 24.6 mL H2 (L h)-1 and a total H2 production to 4.1 ± 0.2 L L-1. The non-sterile operation was implemented as a way of process simplification, but the total H2 production decreased by 59% due to the FW native microorganisms. To counteract this effect, FW was submitted to acid, microwave (MW), and combined acid and MW pretreatment. The application of 4 min MW, 550 W, efficiently controlled the FW microbial counts. The Clostridium butyricum bioaugmented conversion of MW-pretreated FW accelerated the H2 production to 406.2 ± 8.1 mL (L h)-1 and peaked the total H2 production and conversion yield to 4.6 ± 0.5 L L-1 and 234.6 ± 55.6 mL (g sugar)-1, respectively. These results exceeded in 63, 12 and 4%, respectively, the H2 productivity, total production and sugar conversion yield obtained under sterile conditions, and are encouraging for the future implementation of increasingly responsible waste valorisation practices.

Abstract
Objective: To characterize clinically all of the patients with spontaneous pneumomediastinum (SPM) admitted to an adult pulmonology ward in Lisbon, Portugal. Methods: This was a retrospective descriptive study of all adult patients (≥ 18 years of age) diagnosed with SPM between January of 2004 and September of 2015. Results: At least one predisposing factor was identified in most (88.9%) of the 18 patients who presented with SPM during the study period. With regard to precipitating factors, bouts of cough were present in 50.0% of the patients. Other precipitating factors included a sudden increase in tobacco consumption, inhaled drug use, occupational inhalation of varnish fumes, intense exercise, and vomiting. The most common complaints were dyspnea (in 83.3%) and chest pain (in 77.8%). Other complaints included cough, neck pain, dysphagia, and odynophagia. Subcutaneous emphysema was found in most of the patients. The diagnosis of SPM was based on chest X-ray findings in 61.1% of the patients. Conclusions: Although SPM is a rare condition, it should be considered in the differential diagnosis of chest pain and dyspnea. It can develop without a triggering event or conclusive findings on a chest X-ray, which is usually sufficient for diagnosis.

Abstract
BACKGROUND Olanzapine is an orexigenic antipsychotic drug associated with serious metabolic adverse effects in humans. Development of valid rodent models for antipsychotic-induced metabolic adverse effects is hampered by the fact that such effects occur in females only. Estradiol is a predominant female hormone that regulates energy balance. We hypothesized that the female-specific hyperphagia and weight gain induced by olanzapine in the rat are dependent on the presence of estrogens. METHODS Female sham-operated or ovariectomized rats were treated with a single injection of olanzapine depot formulation. Food intake, body weight, plasma lipids, lipogenic gene expression, energy expenditure, and thermogenic markers including brown adipose tissue uncoupling protein 1 protein levels were measured. Olanzapine was also administered to ovariectomized rats receiving estradiol replacement via the subcutaneous (peripheral) or intracerebroventricular route. RESULTS Orexigenic effects of olanzapine were lost in ovariectomized female rats. Ovariectomized rats treated with olanzapine had less pronounced weight gain than expected from their food intake. Accordingly, brown adipose tissue temperature and protein levels of uncoupling protein 1 were elevated. Replacement in ovariectomized rats with either peripherally or centrally administered estradiol reduced food intake and body weight. Cotreatment with olanzapine blocked the anorexigenic effect of peripheral, but not central estradiol. CONCLUSIONS Our results indicate that the ovarian hormone estradiol plays an important role in olanzapine-induced hyperphagia in female rats and pinpoint the complex effects of olanzapine on the balance between energy intake and thermogenesis.

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
INTRODUCTION Immune profile for influenza viruses is highly changeable over time. Serological studies can assess the prevalence of influenza, estimate the risk of infection, highlight asymptomatic infection rate and can also provide data on vaccine coverage. The aims of the study were to evaluate pre-existing cross-protection against influenza A(H3) drift viruses and to assess influenza immunity in the Portuguese population. MATERIALS AND METHODS We developed a cross-sectional study based on a convenience sample of 626 sera collected during June 2014, covering all age groups, both gender and all administrative health regions of Portugal. Sera antibody titers for seasonal and new A(H3) drift influenza virus were evaluated by hemagglutination inhibition assay (HI). Seroprevalence to each seasonal influenza vaccine strain virus and to the new A(H3) drift circulating strain was estimated by age group, gender and region and compared with seasonal influenza-like illness (ILI) incidence rates before and after the study period. RESULTS Our findings suggest that seroprevalences of influenza A(H3) (39.9%; 95% CI: 36.2-43.8) and A(H1)pdm09 (29.7%; 95% CI: 26.3-33.4) antibodies were higher than for influenza B, in line with high ILI incidence rates for A(H3) followed by A(H1)pdm09, during 2013/2014 season. Low pre-existing cross-protection against new A(H3) drift viruses were observed in A(H3) seropositive individuals (46%). Both against influenza A(H1)pdm09 and A(H3) seroprotection was highest in younger than 14-years old. Protective antibodies against influenza B were highest in those older than 65years old, especially for B/Yamagata lineage, 33.3% (95% CI: 25.7-41.9). Women showed a high seroprevalence to influenza, although without statistical significance, when compared to men. A significant decreasing trend in seroprotection from north to south regions of Portugal mainland was observed. CONCLUSIONS Our results emphasize that low seroprotection increases the risk of influenza infection in the following winter season. Seroepidemiological studies can inform policy makers on the need for vaccination and additional preventive measures.

Abstract
The intra-axonal events governing formation of presynaptic terminals are still poorly understood. Pinto et al. reveal a mechanism by which a localized decrease in proteasome degradation and resultant accumulation of polyubiquitinated proteins at nascent sites signal assembly of presynaptic terminals. Differentiation of the presynaptic terminal is a complex and rapid event that normally occurs in spatially specific axonal regions distant from the soma; thus, it is believed to be dependent on intra-axonal mechanisms. However, the full nature of the local events governing presynaptic assembly remains unknown. Herein, we investigated the involvement of the ubiquitin–proteasome system (UPS), the major degradative pathway, in the local modulation of presynaptic differentiation. We found that proteasome inhibition has a synaptogenic effect on isolated axons. In addition, formation of a stable cluster of synaptic vesicles onto a postsynaptic partner occurs in parallel to an on-site decrease in proteasome degradation. Accumulation of ubiquitinated proteins at nascent sites is a local trigger for presynaptic clustering. Finally, proteasome-related ubiquitin chains (K11 and K48) function as signals for the assembly of presynaptic terminals. Collectively, we propose a new axon-intrinsic mechanism for presynaptic assembly through local UPS inhibition. Subsequent on-site accumulation of proteins in their polyubiquitinated state triggers formation of presynapses.

Abstract
AMP-activated protein kinase (AMPK) in the ventromedial nucleus of the hypothalamus (VMH) and orexin (OX) in the lateral hypothalamic area (LHA) modulate brown adipose tissue (BAT) thermogenesis. However, whether these two molecular mechanisms act jointly or independently is unclear. Here, we show that the thermogenic effect of bone morphogenetic protein 8B (BMP8B) is mediated by the inhibition of AMPK in the VMH and the subsequent increase in OX signaling via the OX receptor 1 (OX1R). Accordingly, the thermogenic effect of BMP8B is totally absent in ox-null mice. BMP8B also induces browning of white adipose tissue (WAT), its thermogenic effect is sexually dimorphic (only observed in females), and its impact on OX expression and thermogenesis is abolished by the knockdown of glutamate vesicular transporter 2 (VGLUT2), implicating glutamatergic signaling. Overall, our data uncover a central network controlling energy homeostasis that may be of considerable relevance for obesity and metabolic disorders. Central BMP8B modulates BAT thermogenesis and browning of WAT AMPK in the VMH mediates central BMP8B actions OX in the LHA mediates central BMP8B actions The AMPK(VMH)-OX(LHA) axis is a functional neuronal pathway regulating energy balance

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
During gestation, hyperphagia is necessary to cope with the metabolic demands of embryonic development. There were three main aims of this study: Firstly, to investigate the effect of pregnancy on hypothalamic fatty acid metabolism, a key pathway for the regulation of energy balance; secondly, to study whether pregnancy induces resistance to the anorectic effect of fatty acid synthase (FAS) inhibition and accumulation of malonyl-coenzyme A (CoA) in the hypothalamus; and, thirdly, to study whether changes in hypothalamic AMPK signaling are associated with brown adipose tissue (BAT) thermogenesis during pregnancy. Our data suggest that in pregnant rats, the hypothalamic fatty acid pathway shows an overall state that should lead to anorexia and elevated BAT thermogenesis: decreased activities of AMP-activated protein kinase (AMPK), FAS, and carnitine palmitoyltransferase 1, coupled with increased acetyl-CoA carboxylase function with subsequent elevation of malonyl-CoA levels. This profile seems dependent of estradiol levels but not prolactin or progesterone. Despite the apparent anorexic and thermogenic signaling in the hypothalamus, pregnant rats remain hyperphagic and display reduced temperature and BAT function. Actually, pregnant rats develop resistance to the anorectic effects of central FAS inhibition, which is associated with a reduction of proopiomelanocortin (POMC) expression and its transcription factors phospho-signal transducer and activator of transcription 3, and phospho-forkhead box O1. This evidence demonstrates that pregnancy induces a state of resistance to the anorectic and thermogenic actions of hypothalamic cellular signals of energy surplus, which, in parallel to the already known refractoriness to leptin effects, likely contributes to gestational hyperphagia and adiposity.

Abstract
Estrogens play a major role in the modulation of energy balance through central and peripheral actions. Here, we demonstrate that central action of estradiol (E2) inhibits AMP-activated protein kinase (AMPK) through estrogen receptor alpha (ERα) selectively in the ventromedial nucleus of the hypothalamus (VMH), leading to activation of thermogenesis in brown adipose tissue (BAT) through the sympathetic nervous system (SNS) in a feeding-independent manner. Genetic activation of AMPK in the VMH prevented E2-induced increase in BAT-mediated thermogenesis and weight loss. Notably, fluctuations in E2 levels during estrous cycle also modulate this integrated physiological network. Together, these findings demonstrate that E2 regulation of the VMH AMPK-SNS-BAT axis is an important determinant of energy balance and suggest that dysregulation in this axis may account for the common changes in energy homeostasis and obesity linked to dysfunction of the female gonadal axis.

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
Recent data suggest that ghrelin exerts its orexigenic action through regulation of hypothalamic AMP-activated protein kinase pathway, leading to a decline in malonyl-CoA levels and desinhibition of carnitine palmitoyltransferase 1A (CPT1A), which increases mitochondrial fatty acid oxidation and ultimately enhances the expression of the orexigenic neuropeptides agouti-related protein (AgRP) and neuropeptide Y (NPY). However, it is unclear whether the brain-specific isoform CPT1C, which is located in the endoplasmic reticulum of neurons, may play a role in this action. Here, we demonstrate that the orexigenic action of ghrelin is totally blunted in CPT1C knockout (KO) mice, despite having the canonical ghrelin signaling pathway activated. We also demonstrate that ghrelin elicits a marked upregulation of hypothalamic C18:0 ceramide levels mediated by CPT1C. Notably, central inhibition of ceramide synthesis with myriocin negated the orexigenic action of ghrelin and normalized the levels of AgRP and NPY, as well as their key transcription factors phosphorylated cAMP-response element-binding protein and forkhead box O1. Finally, central treatment with ceramide induced food intake and orexigenic neuropeptides expression in CPT1C KO mice. Overall, these data indicate that, in addition to formerly reported mechanisms, ghrelin also induces food intake through regulation of hypothalamic CPT1C and ceramide metabolism, a finding of potential importance for the understanding and treatment of obesity.
