Abstract
The context-sensitivity of cognition has been demonstrated across a wide range of cognitive functions such as perception, memory, judgement and decision making. A related term, 'contextuality', has appeared from the field of quantum cognition, with mounting empirical evidence demonstrating that cognitive phenomena are sometimes contextual. Contextuality is a subtle notion that influences how we must view the properties of the cognitive phenomenon being studied. This article addresses the questions: What does it mean for a cognitive phenomenon to be contextual? What are the implications of contextuality for probabilistic models of cognition? How does contextuality differ from context-sensitivity? Starting from George Boole's "conditions of possible experience", we argue that a probabilistic model of a cognitive phenomenon is necessarily subject to an assumption of realism. By this we mean that the phenomenon being studied is assumed to have cognitive properties with a definite value independent of observation. In contrast, quantum cognition holds that a cognitive property maybe indeterminate, i.e., its properties do not have well established values prior to observation. We argue that indeterminacy is sufficient for incompatibility between cognitive properties. In turn, incompatibility is necessary for their contextuality. The significance of this argument for cognitive psychology is the following:if a cognitive phenomenon is found to be contextual, then there is reason to believe it may be indeterminate. We illustrate by means of two crowdsourced experiments how context-sensitivity and contextuality of cognitive properties in the form of facial trait judgements can be characterized from empirical data. Finally, we conceptually and formally contrast contextuality with context-sensitivity. We propose that both involve a form of context dependence, with causality being the differentiating factor: the context dependence in context-sensitivity has a causal basis, whereas the context dependence in contextuality is acausal. The resulting implications for probabilistic models of cognition are discussed.

Abstract
Introduction
Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis commonly begins with a prodromal phase characterized by flu-like symptoms, subsequently the patients experience a rapid deterioration with psychiatric symptoms that may include anxiety, irritability, insomnia, paranoia, aggression, auditory or visual hallucinations, sexual disinhibition, mania, cognitive disorder, and psychosis; seizures; motor and autonomic dysfunction. The triggers of the disorder comprise viral infections, tumors, and other unknown factors. Taking in count the prominence of psychiatric symptoms, it is relevant to rise the question whether patients with anti-NMDA receptor encephalitis are being misdiagnosed with psychiatric disorders.
Objectives
Non-systematic literature review of the relationship between anti-NMDA receptor encephalitis and psychiatric disorders.
Methods
From the review performed, 2 studies stand out: In one study, 459 serum samples for NMDA receptor antibodies were evaluated. The analysis compared samples from patients diagnosed with schizophrenia, major depressive disorder, and borderline personality disorder with nonpsychiatric controls. In another study, serum was obtained prospectively from a cohort (n = 46) of patients at first presentation of psychosis and NMDA receptor antibodies were measured.
Results
In the first study, the authors found that 9.9%, 2.8%, and 0% of patients with schizophrenia, major depressive disorder, and borderline personality disorder, respectively, were antibody positive. In the second study, it was found that 7% of the patients were serum NMDA receptor antibody positive.
Conclusions
It is unclear yet if patients with primary psychotic disorders have higher rates of pathogenic NMDA receptor antibodies. More evidence is needed to study this relationship.
Disclosure
No significant relationships.

Abstract
Farm animals are frequently affected by a group of diseases with a rapid clinical course, caused by Clostridium spp. and immunization is essential to provide protection. However, the current manufacturing platform for these vaccines has disadvantages and the main alternative is the use of an expression system that uses Escherichia coli to obtain recombinant vaccine antigens. In this chapter we describe procedures for cloning, expression and characterization of recombinant toxins from Clostridium spp. produced in E. coli for veterinary vaccine applications.

Abstract
PURPOSE To investigate the prognostic value of interim PET (PETi) in adult HL patients, comparing visual with semiquantitative analysis. MATERIAL AND METHODS Retrospective analysis of Hodgkin's lymphoma (HL) patients diagnosed between 2012 and 2016 in the Onco-hematology Department of Instituto Português de Oncologia - Porto (median follow-up: 46.5 months [2.6-66.4]). Fifty-eight patients with available PET at diagnosis (PET0) and PETi data were included. PETi scans were analyzed according to Deauville 5-point scale (5-PS), and cut-off values for changes in maximum standardized uptake value [SUVmax], peak SUV [SUVpeak], metabolic tumour volume [MTV] and total lesion glycolysis index [TLG] between PETi and PET0 were computed using ROC analysis. Visual and semiquantitative data were compared with each other in the prediction of patient outcomes. RESULTS Semiquantitative analysis obtained a higher sensitivity for persistent/relapsed disease compared to the 5-PS (70% vs. 10%, respectively), but lower specificity. It also demonstrated better predictive performance for response to first-line therapy (negative predictive value >92%). The positive predictive value was similar for all five measurements. At 60 months of follow-up, there was a significant difference between the progression free survival (PFS) curves of patients with positive and negative PETi according to ΔSUVmax (56.9% vs. 88.0%, p<0.05), ΔSUVpeak (55.9% vs. 88.1%, p<0.05), ΔMTV (35.3% vs. 88.7%, p<0.05), and ΔTLG (42.4% vs. 88.1%, p<0.05). Statistical significance was not reached when considering 5-PS results. DISCUSSION PETi interpretation according to a semiquantitative approach appears to discriminate HL patients better than the visual 5-PS analysis. This could allow better detection of persistent or early relapsed disease, while a negative PETi result could support de-escalating therapy intensity.

Abstract
A patient suffering from metastatic pancreatobiliary adenocarcinoma was referred to our hospital's stomatology department after a rapidly progressing swelling in the right mandibular angle, trismus and preauricular pain of 3-month duration. A mandible CT scan showed extensive bone rarefaction and a thickening of the contiguous soft tissues that involved the medial masseter and pterygoid muscle. The morphological findings and immunohistochemical profile were compatible with bone metastasis from pancreatic adenocarcinoma. Therefore, palliative treatment was proposed to the patient. Pancreatic cancer metastases to the oral cavity are extremely rare and characterized by its poor prognosis. Herein we describe the ninth case of metastatic spread to the jaw which is also remarkably the longest surviving reported case up to date.

Abstract
Working alongside local stakeholders, members of the French-African Pediatric Oncology Group developed a 3-year program to train pediatric oncology teams from 15 French-speaking countries in Africa in using analgesics and providing palliative care. This program was rolled out in three phases: initial training, in situ assessment, and advanced training in selected topics. To access this program, multidisciplinary teams had to come up with a project to improve their existing palliative care and pain management practices, and commit themselves to implementing it. All the teams invited agreed to take part in the program, which explicitly broached a subject that is often avoided in oncology teaching. The first phase was rolled out in 2017, with 65 trainees from 19 units attending one of three sessions held in Dakar, Senegal, Abidjan, Côte d'Ivoire, and Rabat, Morocco. The subsequent assessment revealed that only half the teams had started to implement their projects. The advanced training phase was therefore adjusted accordingly. A collective training session held in Marseille was attended by 15 trainees from seven teams whose projects were already underway, while in situ mentoring was provided for six other teams, through French-African twinnings in four cases. The length and openness of the program meant that we were able to identify and share the units' diverse realities, and fine-tune their projects accordingly, as well as plan ways of continuing the training both locally and collectively.

Abstract
AIM The aim of the present study was to examine the vaccine immune response in ewes supplemented with Bacillus toyonensis BCT-7112T during a period of 5-day supplementation before vaccination against a recombinant Clostridium perfringens epsilon toxin (rETX). METHODS AND RESULTS Ewes were vaccinated with 200 µg of rETX adjuvanted with 10% aluminium hydroxide. The treat group was orally supplemented with B. toyonensis BCT-7112T (3 × 108 viable spores) for 5 days prior to the first and second vaccination. Ewes supplemented with B. toyonensis BCT-7112T showed higher neutralizing antibody titres than the non-supplemented ewes (P < 0·05), with an increase in serum levels for total IgG anti-rETX by 3·2-fold (P < 0·0001), and for both IgG isotypes IgG1 and IgG2 by 2·1-fold and 2·3-fold (P < 0·01), respectively, compared with the control group. The peripheral blood mononuclear cells of ewes in the supplemented group had a higher (P < 0·05) cytokine mRNA transcription levels for IL-2 (6·4-fold increase), IFN-γ (2·9-fold increase) and transcription factor Bcl6 (2·3-fold increase) compared with the control group. CONCLUSION We conclude that a 5 days of supplementation with B. toyonensis BCT-7112T prior vaccination is sufficient to significantly improve the humoral immune response of ewes against C. perfringens recombinant ETX vaccine. SIGNIFICANCE AND IMPACT OF THE STUDY These findings open a new perspective in the utilization of B. toyonensis BCT-7112T as an immunomodulator since a 5 days period of probiotic supplementation is sufficient to improve the vaccine immune response.

Abstract
OBJECTIVES Earlier studies have demonstrated the use of inactivated recombinant E. coli (bacterins), to protect against Clostridium spp. in vaccinated animals. These bacterins have a simpler, safer, and faster production process. However, these bacterins carry expression plasmids, containing antibiotic resistance gene, which could be assimilate accidentally by environmental microorganisms. Considering this, we aimed to impair this plasmids using formaldehyde at different concentrations. RESULTS This compound inactivated the highest density of cells in 24 h. KanR cassette amplification was found to be impaired with 0.8% for 24 h or 0.4% for 72 h. Upon electroporation, E. coli DH5α ultracompetent cells were unable to acquire the plasmids extracted from the bacterins after inactivation procedure. Formaldehyde-treated bacterins were incubated with other viable strains of E. coli, leading to no detectable gene transfer. CONCLUSIONS We found that this compound is effective as an inactivation agent. Here we demonstrate the biosafety involving antibiotic resistance gene of recombinant E. coli vaccines allowing to industrial production and animal application.

Abstract
Botulism is a neuroparalytic intoxication, usually fatal, caused by the botulinum toxins (BoNTs). Vaccination is the best-known strategy to prevent this disease in ruminants. Serotypes C and D and their variants CD and DC are the main types responsible for botulism in bovine and buffaloes in Brazil and cattle in Japan and Europe. Brazil has a herd of approximately 1.39 million buffaloes and is the largest producer in the Western world. This study aimed to assess the humoral immune response of buffaloes during the 12-month period after vaccination against BoNT serotypes C and D with a recombinant vaccine in three different concentrations (100, 200, and 400 μg) of non-purified recombinant proteins (Vrec) and also with a bivalent commercial toxoid (Vcom). Vrec400 was the best vaccine among those tested because it induced higher levels of antibodies and maintained higher levels of antibodies for the longest time, while Vrec200 could be considered the most cost-effective vaccine for large-scale production. None of the vaccines were able to promote continuous immunological protection within the timeframe proposed by the current Brazilian vaccination protocol. Further studies should focus on vaccine adjustments to ensure continued humoral protection against botulism.

Abstract
Botulism is a paralytic disease caused by the intoxication of neurotoxins produced by Clostridium botulinum. Among the seven immunologically distinct serotypes of neurotoxins (BoNTs A - G), serotypes C and D, or a chimeric fusion termed C/D or D/C, are responsible for animal botulism. The most effective way to prevent botulism in cattle is through vaccination; however, the commercially available vaccines produced by detoxification of native neurotoxins are time-consuming and hazardous. To overcome these drawbacks, a non-toxic recombinant vaccine was developed as an alternative. In this study, the recombinant protein vaccine was produced using an Escherichia coli cell-based system. The formaldehyde-inactivated E. coli is able to induce 7.45 ± 1.77 and 6.6 ± 1.28 IU/mL neutralizing mean titers against BoNTs C and D in cattle, respectively, determined by mouse neutralization bioassay, and was deemed protective by the Brazilian legislation. Moreover, when the levels of anti-BoNT/C and D were compared with those achieved by the recombinant purified vaccines, no significant statistical difference was observed. Cattle vaccinated with the commercial vaccine developed 1.33 and 3.33 IU/mL neutralizing mean titers against BoNT serotypes C and D, respectively. To the best of our knowledge, this study is the first report on recombinant E. coli bacterin vaccine against botulism. The vaccine was safe and effective in generating protective antibodies and, thus, represents an industry-friendly alternative for the prevention of cattle botulism.

Abstract
Many rural areas of Latin America and the Caribbean (LAC) region are economically depressed. Rural sewage treatment in most areas of LAC is deficient or non-existent. Consequently, the possibility of generating economic revenue from treated sewage is an attractive option for deprived areas of developing countries. Given its peculiar characteristics, rural sewage may be coupled with biological systems such as algae for nutrient cycling. Acceptable algae growth and nutrient elimination were obtained from rural sewage whose treatment may have fallen short of current disposal standards. In this study, aerobic systems working on an 8-month cycle at three different volumetric loading rates (Bv) were assessed in relation to the lifetime growth of three algae strains native to Ecuador. Results indicate Chlorella sp. M2 as the optimal algal strain, with the highest growth rate at Bv of 1 g COD L-1 d- 1 and a removal of organic-N (30%), PO4 3--P (87%) and NH4 +-N (95%). Concomitantly, the kinetic constants of the sewage resulted in a low biomass yield coefficient, making the proposed system highly suitable for developing countries. Finally, the proposed partial recovery stream method, combining nutrient recovery with economic resource generation, appears to contain great potential.

Abstract
BACKGROUND AND AIMS The long-term relations between excessive adiposity in early childhood and unfavourable cardiometabolic profiles in later ages are not yet completely understood. We aimed to assess the associations between birth weight (BW) and BMI from 6 months to 6 years of age, with biomarkers indicative of low-grade inflammation, insulin resistance and lipid profiles in adolescence. METHODS AND RESULTS Retrospective school-based study with 415 Portuguese adolescents (220 girls), mean age of 14.08 ± 1.6 years old. Anthropometric data from birth to 6 years old was extracted from individual child health book records. Actual weight and height were measured and BMI calculated. Participants were classified at each time point as normal weight or overweight according to WHO reference values. Biomarkers were obtained from venous blood samples. Linear regressions were used to explore the associations between the biomarkers and early life anthropometric indicators. From 2 years onwards, BMI associated positively with the inflammatory score and HOMA-IR in adolescence. Children who were overweight/obese from 2 to 6 years of age presented significantly higher inflammatory score and HOMA-IR later in adolescence. TC/HDL ratio was also positively associated with BMI from the age of 5 years onwards. The associations between BMI and cardiometabolic outcomes remained positive in adolescence, with overweight adolescents presenting a higher inflammatory score, HOMA-IR and TC/HDL than normal weight adolescents. CONCLUSION A high BMI from an early age was consistently associated with worse inflammatory and lipid profiles and insulin resistance in adolescence. No associations were found between BW and the same studied outcomes.

Abstract
Background and context: In Senegal, pediatric oncology patients arrive at the hospital at advanced stages of disease. Their large tumors, as well as the side effects of chemotherapy make children experience intense pain. In this low-resource setting, morphine supply was quite irregular. Doctors don´t prescribe morphine due to shortages; but few prescriptions also lead to limited orders. A vicious circle with only 1 victim: the patient. Hearing children in pain was agonizing for everyone: patients, caregivers and healthcare practitioners. Aim: This advocacy narrative illustrates how the fight for access to morphine in pediatric oncology has led to both positive and negative externalities. We will highlight ways in which this fight for morphine has provoked political tensions moving the issue forward, but has also affected the careers of health workers involved. Strategy/Tactics: Morphine is a cheap drug, yet it is extremely regulated by international laws. It takes political will to influence national morphine orders. This advocacy strategy was built on raising awareness and setting morphine shortage on the political agenda. Not providing morphine in oncology goes against international standards of care. But most importantly, letting patients suffer without “existing” relief is a breach of basic human right to live - and also die - in dignity. Program/Policy process: Conversations began within the pediatric oncology department. Focus groups highlighted caregivers' feelings of powerlessness before their suffering child. Interviews with key informants (doctor and nurses) were instrumental to a widely diffused Human Rights Watch report exploring the medical and political causes to morphine supply shortages, as well as its psychological repercussions on patient care. A BBC documentary was broadcasted soon after. Subsequently, meetings were held between the Ministry of Health, the National Supply Pharmacy and leading local oncologists. Outcomes: Morphine orders were multiplied by 10, leading to much improved pain management for patients. However, Senegal was portrayed negatively on the international scenes, much to the Health Minister´s dismay. The consequences were incurred by the health workers who contributed to the international publications/reports. What was learned: Health practices can inform policy just like policy can inform health practices. It is a cyclical process. Creating advocacy coalitions and rallying the help of the international community are effective strategies. However, in the political arena, health workers need more than commitment to human rights and quality care. Even in democratic republics, systems can penalise outspoken activists. We have learned that health care practitioners (especially working in public settings) who wish improvement for their patients must learn to be tactical and diplomatic. International partners will return to their home countries, but local actors will pay the high cost of advocacy.

Abstract
BACKGROUND AND AIMS The associations between fruit and vegetable consumption and high blood pressure among adults are well studied. Nonetheless, data on the influence of a low consumption of fruit and vegetables on cardiovascular disease risk, particularly blood pressure, among healthy adolescents are scarce. Therefore, we aim to analyse the associations between fruit and/or vegetable intake and blood pressure over a two-year period in healthy adolescents. METHODS AND RESULTS As part of a cohort, 606 adolescents from the LabMed Physical Activity study were evaluated in 2011 (baseline) and 2013 (follow-up). Blood pressure was measured according to standardized procedures and fruit and vegetable consumption was assessed with a food frequency questionnaire. Anthropometric variables, socioeconomic status, pubertal stage and lifestyle determinants were gathered and used as confounders. Prospective associations between fruit and/or vegetable intake and blood pressure were examined using generalized linear models. Girls who consumed more fruit at baseline had a significant decrease in diastolic blood pressure at follow-up [unstandardized beta: -0.005 mmHg (95%CI: -0.01; -0.0002) (p = 0.038)]. CONCLUSION In apparently healthy adolescents, fruit intake may already start to have an effect in blood pressure. Girls who consumed more fruit exhibited lower levels of diastolic blood pressure.

Abstract
BACKGROUND AND AIMS Muscular fitness is an emerging predictor for cardiovascular disease mortality. The ideal cardiovascular health metrics has been inversely related to a subsequent cardiometabolic health in adulthood. However, evidence regarding muscular fitness and ideal cardiovascular health in adolescents is scarce. This study aimed to examine the longitudinal association between ideal cardiovascular health index and muscular fitness. METHODS AND RESULTS This study cohort consisted of 331 adolescents (183 girls) from the LabMed Physical Activity Study who were followed from 2011 to 2013. Ideal cardiovascular health, as defined by the American Heart Association, was determined as meeting ideal health factors (total cholesterol, blood pressure, and glucose) and behaviors (smoking status, body mass index, physical activity, and diet). Handgrip strength and standing long jump tests assessed muscular fitness and were transformed into standardized values according to age and sex. ANCOVA showed a significant association between the accumulation of ideal cardiovascular health metrics at baseline and muscular fitness indices at follow-up (F(4, 322) = 2.280, p = 0.04). In addition, the higher the number of ideal cardiovascular health metrics accumulated, the higher the likelihood of having a high muscular fitness over a two-year period (p for trend = 0.01), after adjustments for age, sex, pubertal stage and socioeconomic status and muscular fitness at baseline. CONCLUSION The ideal cardiovascular health status during adolescence was associated with high muscular fitness levels over a two-year period.

Abstract
BACKGROUND The B subunit of Escherichia coli heat-labile enterotoxin
(LTB) is a potent mucosal immune adjuvant. However, there is little
information about LTB's potential as a parenteral adjuvant. OBJECTIVES We aimed at evaluating and better understanding rLTB's potential as a
parenteral adjuvant using the fused R1 repeat of Mycoplasma
hyopneumoniae P97 adhesin as an antigen to characterise the
humoral immune response induced by this construct and comparing it to that
generated when aluminium hydroxide is used as adjuvant instead. METHODS BALB/c mice were immunised intraperitoneally with either rLTBR1 or
recombinant R1 adsorbed onto aluminium hydroxide. The levels of systemic
anti-rR1 antibodies (total Ig, IgG1, IgG2a, and IgA) were assessed by
enzyme-linked immunosorbent assay (ELISA). The ratio of IgG1 and IgG2a was
used to characterise a Th1, Th2, or mixed Th1/Th2 immune response. FINDINGS Western blot confirmed rR1, either alone or fused to LTB, remained antigenic;
anti-cholera toxin ELISA confirmed that LTB retained its activity when
expressed in a heterologous system. Mice immunised with the rLTBR1 fusion
protein produced approximately twice as much anti-rR1 immunoglobulins as
mice vaccinated with rR1 adsorbed onto aluminium hydroxide. Animals
vaccinated with either rLTBR1 or rR1 adsorbed onto aluminium hydroxide
presented a mixed Th1/Th2 immune response. We speculate this might be a
result of rR1 immune modulation rather than adjuvant modulation. Mice
immunised with rLTBR1 produced approximately 1.5-fold more serum IgA than
animals immunised with rR1 and aluminium hydroxide. MAIN CONCLUSIONS The results suggest that rLTB is a more powerful parenteral adjuvant than
aluminium hydroxide when administered intraperitoneally as it induced higher
antibody titres. Therefore, we recommend that rLTB be considered an
alternative adjuvant, even if different administration routes are
employed.

Abstract
Botulism is a fatal intoxication caused by botulinum neurotoxins (BoNTs), which are mainly produced by Clostridium botulinum and characterized by flaccid paralysis. The BoNTs C and D are the main serotypes responsible for botulism in animals, including buffaloes. Botulism is one of the leading causes of death in adult ruminants in Brazil due to the high mortality rates, even though botulism in buffaloes is poorly reported and does not reflect the real economic impact of this disease in Brazilian herds. Vaccination is reported as the most important prophylactic measure for botulism control, although there are no specific vaccines commercially available for buffaloes in Brazil. This study aimed to evaluate the humoral immune response of buffalo groups vaccinated with three different concentrations of recombinant proteins (100, 200, and 400 µg) against BoNTs serotypes C and D as well as to compare the groups to each other and with a group vaccinated with a bivalent commercial toxoid. The recombinant vaccine with a concentration of 400 μg of proteins induced the highest titers among the tested vaccines and was proven to be the best choice among the formulations evaluated and should be considered as a potential vaccine against botulism in buffalo.

Abstract
Female genital mutilation (FGM) comprises all procedures involving partial or total removal of the external genitalia and/or any other procedures affecting the female genitalia, for cultural or religious reasons or for nontherapeutic purposes in general. FGM is responsible for a number of short-, medium-, and long-term complications that can engage the vital and functional prognosis, especially in African countries. We report on a case in a 10-year-old girl who underwent genital mutilation, a traditional type of total excision during the neonatal period. She was followed for urethral meatus stenosis, which then was complicated by obstructive chronic kidney failure and urinary sepsis, whose progression was fatal.

Abstract
BACKGROUND AND AIM Muscular fitness and an adherence to the Southern European Atlantic Diet (SEADiet) have been inversely associated with cardiometabolic risk. Our aim was to assess the independent and combined associations of muscular fitness and adherence to the SEADiet on cardiometabolic risk in adolescents. METHODS AND RESULTS A total of 467 Portuguese adolescents (275 girls) participated in this cross-sectional study. Sum of the Z-Scores of Curl-Up and Push-Up tests was used to create a muscular fitness score. Adherence to SEADiet was obtained using a food frequency questionnaire. A cardiometabolic risk score was computed from sum of Z-score of triglycerides, systolic blood pressure, total cholesterol/HDL ratio, HOMA-IR and waist circumference. Adolescents with low muscular fitness and low adherence to the SEADiet had the poorest cardiovascular profile F(5, 452) = 5.074 (p < 0.001) and the highest odds of having a high cardiometabolic risk score (OR = 4.5; 95% CI: 2.1-14) when compared to those with High muscular fitness/High adherence to the SEADiet after adjustments for age, sex, pubertal stage, socioeconomic status, total energy intake, low-energy reporter and cardiorespiratory fitness. CONCLUSIONS Our findings seem suggest that improving muscular fitness as well as an adherence to the SEADiet could be an important strategy to reduce clustered cardiometabolic risk in youth.

Only patients (n=67) who underwent histological analysis of the enucleation specimen (n=68) were followed until the end of the study. RESULTS The tumor measured an average of 3.8cm (2/4.5). Endophytic tumor development was observed in 55 cases (80.8%), exophytic in 6 cases (8.9%) and mixed in 7 cases (10.3%). Retinal detachment was present in 13 cases (19.2%). The RB was well differentiated in 11 cases (16.2%), moderately differentiated in 31 cases (45.6%) and undifferentiated in 26 cases. Optic nerve (ON) invasion was present in 18 cases (26.5%). The tumor was extraretinal in 37 cases (54.4%). The anterior chamber was invaded in 6 cases (8.8%). The global survival at 2 years was 84% and 70% at 5 years. On multivariate analysis, well differentiated tumors and stage pT1 were associated with remission. Retrolaminar ON invasion, massive choroidal invasion and stage pT3 were risk factors for recurrence. Poor tumor differentiation, invasion of the ON resection margin, tumor invasion through the sclera, and stage pT4 were predictive of death. CONCLUSION The pathologist is a principal actor in the management of RB because his account guide the post-surgical management strategy.

Abstract
We describe a patient with a generalized bullous form of Fixed Drug Eruption (FDE) induced by bromhexine, a commonly used drug for respiratory symptoms. This is a rare association and generalized bullous FDE is also very rare. We emphasize the importance of patch tests in identifying the culprit drug.

Abstract
BACKGROUND AND AIM Paradoxically, recent investigations have showed that adiponectin levels are inversely associated with muscle strength. However, to date, there is a lack of knowledge on the relationship between muscular fitness (MF) and adiponectin levels in adolescents. We aimed to examine the independent associations between MF and adiponectin levels in adolescents, controlling for several potential confounders. METHODS AND RESULTS This is a cross-sectional analysis with 529 Portuguese adolescents aged 12-18 years. A MF score was computed as the mean of the handgrip strength and standing long jump standardized values by age and gender. We measured fasting glucose, insulin, HDL-cholesterol, C-reactive protein and adiponectin. Linear regression analysis showed a significant inverse association between adiponectin (Z-score by age and sex) and MF score, after adjustments for age, sex, pubertal stage, socioeconomic status, adherence to the Mediterranean diet, body mass index, HOMA-IR, HDL-cholesterol, C-reactive protein and cardiorespiratory fitness (unstandardized β = -0.176; p < 0.005). Analysis of covariance showed a significant difference between the Low MF/Non-overweight group and the High MF/Non-overweight Group (p < 0.05) and between the Low MF/Non-overweight and High MF/Overweight Group (p < 0.05) (F (5, 523) = 2.262, p = 0.047). CONCLUSION Adiponectin circulating levels are inversely and independently associated with MF. In non-overweight adolescents, those with high levels of MF presented lower levels of adiponectin compared to those with Low MF. Likewise, overweight adolescents with High MF presented lower levels of serum adiponectin than non-overweight adolescents with Low MF.

Abstract
BackgroundInternational professional mobility is a reality, people have skills they can put in the global marketplace. The increasing migration of health professionals to wealthy countries is a phenomenon known as “brain drain”.Objectives/AimsThis work aims to present the push factors that pressure people to migrate from Portugal.MethodsA cross-sectional survey was carried out with the psychiatric trainees in Portugal. A self-administered structured questionnaire was distributed to collect psychiatry trainees’ demographic and educational characteristics.ResultsIn Portugal, the majority of trainees have a Portuguese citizenship. Almost 2/3 did not have a short-mobility experience, and the majority never migrated to another country. Less than half consider staying in Portugal in the next years, and nearly 4/5 have considered leaving the country. Working conditions ranked first as the priority condition to be improved in psychiatry in Portugal, followed by financial conditions. In fact, an attractive job for psychiatry trainees in Portugal must have as the most important feature a pleasant work environment.ConclusionsAn alarming percentage of psychiatry trainees from Portugal intend to migrate. Impact on future career, financial conditions of doctors, job opportunities and better working conditions were some of the motivating factors behind the migration.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionLatest classifications led to an inflamed debate urging for change or validation in the way personality disorders are classified. The placement in psychiatric classifications of several personality disorders, particularly Borderline Personality Disorder (BPD), is also a matter of discussion.Objectives and aimsThe present work aims to question BPDs place in classification alongside with other personality disorders, rather than focusing on the algorithms used to classify it. The authors review updated literature on core features of the disorder collected from online scientific databases.ResultsStudies reveal that the stability of the diagnosis of BPD over the longer term is less than what standard general definitions of personality disorders would appear to require. It is a chronic and debilitating syndrome with severe functional and psychosocial impairment that remain relevant when comparing to other personality disorders. Additionally, these measures show further declines over time in spite of improvement in psychopathology, in contrast to what happens with other personality disorders. Several misconceptions may have led to the placement of BPD on former axis II, namely being a direct consequence of trauma and merely explained by environmental factors. However, recent research on heritability shows the contrary and several neurobiological markers suggest it has got a nature of its own.ConclusionBPD is probably the most studied and validated personality disorder and has substantially greater empirical basis, clinical significance and public health implications, being both enduring and distinct from other personality disorders. We suggest the placement of BPD as major psychiatric disorder in classifications.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionThere is growing evidence of the importance of nutrition in mental disorders. Gut microbiota, influenced by environmental factors such as diet and stress, has been proposed as one of the players on a dynamic called gut-brain axis, which is thought to have an influence on behaviour and mental health.Objectives and aimsTo summarize recent evidence on the topic, and its potential role in psychiatric interventions.MethodsThe authors review updated literature collected from online scientific databases.ResultsThe development of the brain itself has been shown to be influenced by the gut microbiome. Research demonstrates that the composition of the microbiota has influence on behaviour through neuroendocrine and other neuroactive messengers production by the bacteria within the gut lumen. Studies in germ-free animals, animals exposed to bacterial infections, probiotic suplements or antibiotic drugs suggest a role for the gut microbiota in the regulation of anxiety, mood, cognition and pain. The gut microbiome has been implicated in brain disorders including anxiety and depression, multiple sclerosis, Alzheimer's disease, Parkinson's disease, and autism.ConclusionsThe treatment of mental disorders is usually based on pharmacological and psychotherapeutic interventions, and little attention is given to dietary interventions. The emerging field of research focused on the human microbiome suggests an important role for the gut microbiota in influencing brain development, behaviour and mood in humans, and points new strategies for developing novel therapeutics for mental disorders.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Clostridium botulinum is a Gram-positive, spore-forming, anaerobic bacillus that produces a potent neurotoxin. Botulinum neurotoxins (BoNTs) are classified from serotypes A to H, and even though they have similar mechanisms of action, they show preferential hosts. In veterinary medicine, BoNT serotypes C and D are the most important, once several animal species are susceptible to them. Since BoNTs are the most potent toxins known in nature, the best way to control botulism in animals is through vaccination. However, current commercial vaccines are based on inactivated toxins (toxoids) and cells (bacterins) and present many drawbacks, such as a time-consuming production with variable antigen yield and biosafety risks. Recombinant vaccines, especially those produced by Escherichia coli expression system, have proved to be an interesting alternative to overcome these problems. E. coli is a very well-known microorganism that allows the production of large amounts of nontoxic recombinant antigens in a short period using simple culture medium reducing the production complexity and decreasing most of the biosafety risks involved in the process. We describe herein a method for the production of recombinant vaccines for veterinary medicine application, involving initial steps of gene design up to vaccine formulation and evaluation itself.
