Abstract
BACKGROUND Cervical cancer screening remains an essential preventive tool worldwide. First line high-risk Human Papillomavirus (HrHPV) genotyping became gold standard for cervical cancer screening, and has been adopted by several countries, including Portugal. Herein, we aimed to assess the early outcomes of the regional Cervical Cancer Screening Program of Northern Portugal. METHODS The analysis of a representative set of cases evaluated during a one-month period (January 2020), with adequate follow-up was performed. Descriptive analysis was performed. RESULTS Overall, 7278 samples were received, of which 15.2% were HrHPV positive, most of these disclosing a negative result in subsequent liquid-based cytology. Nearly half of the HrHPV-positive women were referred to colposcopy. Within this group, HPV16/18+ cases depicted the higher frequency of high-grade squamous intraepithelial lesion (HSIL) or worse, compared with abnormal cytology or persistent HrHPV infection. Among women with non-HPV16/18 HrHPV infection and negative cytology, which are eligible for repeat sampling in one year, 65% were re-tested. Importantly, nearly half of these cleared HrHPV infection. Furthermore, referral to colposcopy due to HPV16/18 infection and/or abnormal cytology results were associated with > 40% risk for HSIL or worse lesion. CONCLUSIONS Our study confirmed the reliability and effectiveness of first line HrHPV genotyping in the Cervical Cancer Screening Program of Northern Portugal. Nonetheless, it also raised concerns about excessive referral to colposcopy, with the inherent human and financial costs. Thus, further improvement and optimization are key to ensure the sustainability of the program.

Abstract
Early diagnosis of plant diseases is needed to promote sustainable plant protection strategies. Applied predictive modeling over hyperspectral spectroscopy (HS) data can be an effective, fast, cost-effective approach for improving plant disease diagnosis. This study aimed to investigate the potential of HS point-of-measurement (POM) data for in-situ, non-destructive diagnosis of tomato bacterial speck caused by Pseudomonas syringae pv. tomato (Pst), and bacterial spot, caused by Xanthomonas euvesicatoria (Xeu), on leaves (cv. cherry). Bacterial artificial infection was performed on tomato plants at the same phenological stage. A sensing system composed by a hyperspectral spectrometer, a transmission optical fiber bundle with a slitted probe and a white light source were used for spectral data acquisition, allowing the assessment of 3478 spectral points. An applied predictive classification model was developed, consisting of a normalizing pre-processing strategy allied with a Linear Discriminant Analysis (LDA) for reducing data dimensionality and a supervised machine learning algorithm (Support Vector Machine - SVM) for the classification task. The predicted model achieved classification accuracies of 100% and 74% for Pst and Xeu test set assessments, respectively, before symptom appearance. Model predictions were coherent with host-pathogen interactions mentioned in the literature (e.g., changes in photosynthetic pigment levels, production of bacterial-specific molecules, and activation of plants' defense mechanisms). Furthermore, these results were coherent with visual phenotyping inspection and PCR results. The reported outcomes support the application of spectral point measurements acquired in-vivo for plant disease diagnosis, aiming for more precise and eco-friendly phytosanitary approaches.

Abstract
As available tools for crop disease management are scarce, new, effective, and eco-friendly solutions are needed. So, this study aimed at assessing the antibacterial activity of a dried leaf Eucalyptus globulus Labill. aqueous extract (DLE) against Pseudomonas syringae pv. tomato (Pst), Xanthomonas euvesicatoria (Xeu), and Clavibacter michiganensis michiganensis (Cmm). For this, the inhibitory activity of different concentrations of DLE (0, 15, 30, 45, 60, 75, 90, 105, 120, 135, and 250 g L-1) was monitored against the type strains of Pst, Xeu, and Cmm through the obtention of their growth curves. After 48 h, results showed that the pathogen growth was strongly inhibited by DLE, with Xeu the most susceptible species (15 g L-1 MIC and IC50), followed by Pst (30 g L-1 MIC and IC50), and Cmm (45 and 35 g L-1 MIC and IC50, respectively). Additionally, using the resazurin assay, it was possible to verify that DLE considerably impaired cell viability by more than 86%, 85%, and 69% after Pst, Xeu, and Cmm were incubated with DLE concentrations equal to or higher than their MIC, respectively. However, only the treatment with DLE at 120 g L-1 did not induce any hypersensitive response in all pathogens when treated bacterial suspensions were infiltrated onto tobacco leaves. Overall, DLE can represent a great strategy for the prophylactic treatment of tomato-associated bacterial diseases or reduce the application of environmentally toxic approaches.

Abstract
BACKGROUND Although adolescent basketballers differ in body size, shape, and composition, less is known about how these factors interact during physical development. AIM We used ontogenetic allometry to identify the optimal body size and shape characteristics associated with physical performance in adolescent basketball players, and investigated the effects of training experience, training volume, maturity status, and club characteristics on physical performance development. SUBJECTS AND METHODS Two hundred and sixty-four male basketballers, from five age-cohorts (11-15 years of age), were followed consecutively over three years. Three physical performance components, anthropometrics, training information, and biological maturation were assessed bi-annually. Longitudinal multiplicative allometric models were developed. RESULTS Players with a physique that had a dominant ectomorphic component performed better in all physical performance components. When adjusting for confounders other than size, the development of running speed was independent of body size. Players advanced in maturation were physically fitter. Training data had no significant effect on developmental trajectories of running speed or lower body explosive strength. Club characteristics had no significant association with any physical performance trajectories. CONCLUSION Leaner players have advantages in physical performance and individual characteristics play an important role, over and beyond club structure, in developing physical performance.

Abstract
Cervical cancer prevention is based on primary prevention with vaccines against Human Papillomavirus (HPV) and secondary prevention by screening with High-Risk-HPV (Hr-HPV) detection. Since 2017, cervical cancer screening in women aged 25-60 years has been performed in Portugal using Hr-HPV detection, followed by cytology in Hr-HPV-positive cases. Herein we report the prevalence of Hr-HPV genotypes and cytological abnormalities among 462 401 women (mean age: 43.73 ± 10.79; median age: 45; range: 24-66 years) that participated in the Regional Cervical Cancer Screening Program of the Northern Region of Portugal, performed between August 2016 and December 2021. Overall, we describe a prevalence rate of 12.50% for Hr-HPV varying from 20.76% at age 25% to 8.32% at age 64. The five most common Hr-HPV genotypes identified were HPV-68 (16.09%), HPV-31 (15.30%), HPV-51 (12.96%), HPV-16 (11.06%), and HPV-39 (11.01%). The prevalence of Hr-HPV included in the nonavalent vaccine (HPV-9valent) was 55.00% ranging from 47.78% to 59.18% across different age groups. Considering positive Hr-HPV cases, 65.68% had a Negative for Intraepithelial Lesion or Malignancy (NILM) cytology, 20.83% atypical squamous cells of undetermined significance (ASC-US), 8.85% Low-Grade Squamous Intraepithelial Lesion (LSIL), 1.65% High-Grade Squamous Intraepithelial Lesion (HSIL), 2.85% ASC-H, 0.09% Atypical Glandular Cells, 0.02% Adenocarcinomas, and 0.02% Squamous Cell Carcinoma (SCC). Our analysis revealed that HPV-9val genotypes were responsible for 52.13% NILM, 59.21% ASC-US, 55.06% LSIL, 90.14% HSIL, 83.50% ASC-H, and 100.00% SCC. Furthermore, multiple Hr-HPV infections (risk ratio [RR] = 1.46; 95% confidence interval [CI] 1.34-1.58), HPV-16/18 (RR = 5.16; 95% CI 4.75-5.93), or HPV-9val genotypes (RR = 5.23; 95% CI 4.68-5.85) were associated with a significant risk of developing > HSIL (p < 0.001). To date, this is the largest study on Hr-HPV genotyping in cervical cancer screening that includes data from a complete cycle of the screening program. Our findings suggest a high prevalence of HPV-9valent genotypes and a significant association with an increased risk of developing > HSIL. This constitutes important data for health authorities, which may help define the future of vaccination and cervical cancer screening strategies.

Abstract
Background Fire blight is a destructive disease of pome trees, caused by Erwinia amylovora, leading to high losses of chain-of-values fruits. Major outbreaks were registered between 2010 and 2017 in Portugal, and the first molecular epidemiological characterization of those isolates disclosed a clonal population with different levels of virulence and susceptibility to antimicrobial peptides. Methods This work aimed to further disclose the genetic characterization and unveil the phenotypic diversity of this E. amylovora population, resorting to MLSA, growth kinetics, biochemical characterization, and antibiotic susceptibility. Results While MLSA further confirmed the genetic clonality of those isolates, several phenotypic differences were recorded regarding their growth, carbon sources preferences, and chemical susceptibility to several antibiotics, disclosing a heterogeneous population. Principal component analysis regarding the phenotypic traits allows to separate the strains Ea 630 and Ea 680 from the remaining. Discussion Regardless the genetic clonality of these E. amylovora strains isolated from fire blight outbreaks, the phenotypic characterization evidenced a population diversity beyond the genotype clonality inferred by MLSA and CRISPR, suggesting that distinct sources or environmental adaptations of this pathogen may have occurred. Conclusion Attending the characteristic clonality of E. amylovora species, the data gathered here emphasizes the importance of phenotypic assessment of E. amylovora isolates to better understand their epidemiological behavior, namely by improving source tracking, make risk assessment analysis, and determine strain-specific environmental adaptations, that might ultimately lead to prevent new outbreaks.

Abstract
Bacterial canker of the kiwifruit caused by the etiological agent Pseudomonas syringae pv. actinidiae is the most severe disease in kiwifruit production. Since 2008 a hypervirulent Psa biovar 3 has spread rapidly worldwide. Different genomic and phenotypic approaches have been used to understand the origin of the dissemination and geographical evolution of populations associated with this pandemic. This study aimed to characterize the genetic and phenotypic diversity of 22 Psa isolates collected in different regions of Portugal between 2013 and 2017. Genotypic and phenotypic characterization was based on Multi-Locus Sequence Analysis (MLSA), motility, IAA production, Biolog GEN III, and copper sensitivity. No polymorphisms were detected for the concatenated sequence (1950 bp) of the housekeeping genes gltA, gapA, gyrB, and rpoD. Results support the analysed Portuguese Psa isolates (2013–2017) belonging to Psa3, and MLSA indicates high genetic clonality and stability of these populations. The phenotypic analysis through Biolog revealed a heterogeneous pattern in the Psa collection and its position in the Pseudomonas complex. This heterogeneity reflects a genomic diversity that may reflect distinct adaptive trends associated with the environmental conditions and widespread. The Portuguese Psa collection showed no resistance to copper. This information is relevant to kiwi producers that predominantly use Cu-treatments to control kiwifruit bacterial canker.

Abstract
Introduction
Attention-Deficit/Hyperactivity Disorder (ADHD) is characterized by impairing symptoms of inattention and/or hyperactivity/impulsivity. Although Emotional Dysregulation (ED) is not current criteria for ADHD, several clinical, imaging and genetic studies have been suggesting its inclusion. ED seems to impair social and occupational capacities, leading to poor quality life. In this regard, managing this situation is fundamental.
Objectives
ED in ADHD review and its management, including pharmacological and nonpharmacological approaches.
Methods
Non-systematic review through literature using databases as Pubmed and UpToDate. Keywords used: Attention-Deficit/Hyperactivity Disorder, Emotional Dysregulation, management, pharmacotherapy.
Results
Literature refers to ADHD drugs, such as psychostimulants and atomoxetine, as the first line managing ED. However, some studies demonstrated that ADHD drugs have lower efficacy while treating emotional symptoms, when compared to attention or hyperactivity/impulsivity symptom control. Other medications, such as antidepressants or mood stabilizers, are not considered due to low efficacy and side effects (such as irritability or suicidality behaviour worsening). Regarding non pharmacological approaches, there have been results with cognitive behavioral treatment, and management techniques for anger, frustration and communication skills.
Conclusions
Although the majority of studies demonstrate psychostimulants and atomoxetine role, there is an important lack of information regarding management of ADHD emotional dysregulation. It is a multifactorial condition, and, as such, non pharmacological and pharmacological management are needed to address this issue. More research is necessary, in order to improve patients’ quality of life.

Abstract
Introduction Capgras and Fregoli delusions are psychotic complex conditions that integrate a larger group of Delusional Misidentification Syndromes (DMS), where the patient misidentifies people, places or objects. Objectives Review of the literature and exposure of a case report of a first psychotic episode with DMS. Methods Case report and a nonsystematic review through databases. With the keywords: Capgras; Fregoli; DMS. Results This case presents a caucasian male, 34-year-old, with no personal or family history of psychiatric pathology. He was taken to the emergency service, due to behavior disorder with verbal aggressiveness to his mother. During the psychiatric emergency he was restless, with accelerated speech and presented Capgras and Fregoli delusion. He believed that his mother had been replaced by an imposter and that the doctor was actually his childhood friend disguised, all with the intention of harming him. The patient was hospitalized, analytical and brain scan show no abnormally. Improvement in symptoms was been seen when a long-term injectable antipsychotic was started. The diagnosis was Bipolar type I disorder. Conclusions DSM are more frequent than previously considered, they often occur in association with psychiatric or neurological disorders. Case reports like this one helps to clarify the association between DMS and psychiatric disorders. Given the high incidence of DMS, it is essential to recognize them, carry out an early treatment and be alert to other psychopathological or neurological symptoms that may coexist.

Abstract
Introduction
Gender dysphoria is characterized by a mismatch between the biological sex and gender identity of a person, frequently associated to distress or discomfort. Many transgender people will seek professional help to obtain a congruence between the gender identity and the body.
Objectives
Brief review of the literature in the field of mental health and gender dysphoria.
Methods
Review of the literature, through research in the PubMed database, using the following keywords: “gender dysphoria”, “mental health”, “psychiatric disorders”.
Results
Although the true prevalence of gender dysphoria (GD) is unknown, several studies indicated that the prevalence of psychiatric disorders in this population is elevated. In comparison with the general population, persons with GD have higher rates of depressive symptoms (64.5%), suicidality (42.9%), substance use disorders (40.2%), general distress (33.8%), anxiety (25.9%), discrimination, and stigma, that contribute to mental health problems. Even though, we cannot reach firm conclusions due to the lack of controlled studies exploring psychiatric disorders on GD people versus controls. An interdisciplinary approach to the health and well-being of this population is highly recommended. Social support, community connectedness, and effective coping strategies appear beneficial.
Conclusions
Individuals with GD have higher rates of psychiatric disorders and social stressors. Healthcare professionals should have a basic understanding on GD. Management should be individualized and may involve a multidisciplinary team. It would be important to have access to more controlled studies in order to achieve a better characterization of the prevalence of mental health disorders in this population.

Abstract
Introduction Schizophrenia is a complex and multifactorial psychiatric condition characterized by thought, speech, perception and behaviour disorders, and social and occupational impairment. It has been related that viral prenatal infection may contribute to schizophrenia development. As such, there are some hypotheses regarding SARS-Cov-2 prenatal infection and its potential relation with “future” offspring schizophrenia. Objectives Literature review of schizophrenia development and relation with viral infections, and data research of COVID-19 neurotropic effects. Methods Non-systematic review through literature using databases as Pubmed and UpToDate. Keywords used: schizophrenia, prenatal, viral infection, COVID-19, SARS-Cov-2. Results Several studies had shown a relationship between prenatal viral infections, such as Influenza, and development of schizophrenia in the offspring. It relates with viral neurotropism mechanisms and inflammatory processes in the fetal neurology system. Regarding SARS-Cov-2, it is early to assume a relation between prenatal COVID-19 and offspring schizophrenia development. However, literature describes psychiatric manifestations post COVID, such as psychotic and manic episodes. As such, a SARS-Cov-2 neurotropic effect is demonstrated. Conclusions Schizophrenia has a multifactorial etiology. Since prenatal viral infections may interfere and contribute to schizophrenia development, it is logical to assume prenatal SARS-Cov-2 infection may also contribute. It may be relevant to investigate whether these offspring will manifest schizophrenia symptoms. Disclosure No significant relationships.

Abstract
INTRODUCTION In Portugal, a colorectal cancer screening program based on faecal immunochemical test followed by colonoscopy was shown to be cost-effective for individuals between 50 and 74 years old. We report the first findings of the implementation of a population-based program In Northern Portugal. MATERIAL AND METHODS In the pilot phase, eligible subjects were allocated either to a direct mailing invitation or to primary care centers. In the first year of program implementation, we assessed the uptake rate, the faecal immunochemical test -positivity rate, the diagnostic yield of advanced neoplasia, and the quality parameters for post-faecal immunochemical test + colonoscopy. RESULTS We invited 100 501 eligible subjects (49% male with a median age of 55 years). Of these, 5228 participated in the pilot phase and 95 273 participated in the first year of the program. In the first year of the program, the adherence was 29%, with a positivity rate of 5% and a 60% compliance to colonoscopy. The faecal immunochemical test-detection rate of advanced neoplasia was 0.35/1000 subjects, and the positive predictive value at post- faecal immunochemical test + colonoscopy was 44% and 2% for advanced adenoma and invasive cancer, respectively. No major adverse events were reported after colonoscopy. DISCUSSION The suboptimal adherence to faecal immunochemical test and post-faecal immunochemical test + colonoscopy remains the most urgent step to be addressed. CONCLUSION A centralized invitation system based on direct mailing was feasible and both colonoscopy quality and diagnostic yield were adequate antecipating the success of the programme.

Abstract
Cervical cancer remains a health concern. Effective screening programs are critical to reduce the incidence and mortality. High-risk HPV (hr-HPV) testing as primary screening tool discloses high sensitivity but suboptimal specificity. Adequate triage tests to reduce unnecessary colposcopy referrals and overdiagnosis/overtreatment are crucial. Hence, we aimed to validate a panel of DNA methylation-based markers as triage test for women hr-HPV+ in the population-based Regional Cervical Cancer Screening Program of Northern Portugal. Firstly, CADM1, MAL, FAM19A4 and hsa-miR124-2 promoter methylation levels were assessed by multiplex QMSP in a testing set of 402 FFPE tissue samples (159 normal samples and 243 cervical lesions, including 39 low-grade intraepithelial squamous lesions [LSIL], 59 high-grade intraepithelial squamous lesions [HSIL] and 145 cancerous lesions). Then, preliminary validation was performed in 125 hr-HPV+ cervical scrapes (including 59 normal samples, 30 LSIL, 34 HSIL and 2 cancerous lesions). Higher MALme , FAM19A4me and hsa-miR124-2me methylation levels were disclosed in histological HSIL or worse (HSIL+) in testing set. Individually, markers depicted over 86% specificity for HSIL+ detection. In validation set, all these genes significantly differed between histological HSIL+ and low-grade squamous intraepithelial lesions or less. In combination, these markers reached 74% specificity and 61% sensitivity for identification of histological HSIL+. We concluded that host gene methylation might constitute a useful referral triage tool of hr-HPV+ women enrolled in the Cervical Cancer Screening Program of Northern Portugal.

Abstract
BACKGROUND The species Xanthomonas arboricola comprises up to nine pathovars, two of which affect nut crops: pv. juglandis, the causal agent of walnut bacterial blight, brown apical necrosis, and the vertical oozing canker of Persian (English) walnut; and pv. corylina, the causal agent of the bacterial blight of hazelnut. Both pathovars share a complex population structure, represented by different clusters and several clades. Here we describe our current understanding of symptomatology, population dynamics, epidemiology, and disease control. TAXONOMIC STATUS Bacteria; Phylum Proteobacteria; Class Gammaproteobacteria; Order Lysobacterales (earlier synonym of Xanthomonadales); Family Lysobacteraceae (earlier synonym of Xanthomonadaceae); Genus Xanthomonas; Species X. arboricola; Pathovars: pv. juglandis and pv. corylina. HOST RANGE AND SYMPTOMS The host range of each pathovar is not limited to a single species, but each infects mainly one plant species: Juglans regia (X. arboricola pv. juglandis) and Corylus avellana (X. arboricola. pv. corylina). Walnut bacterial blight is characterized by lesions on leaves and fruits, and cankers on twigs, branches, and trunks; brown apical necrosis symptoms consist of apical necrosis originating at the stigmatic end of the fruit. A peculiar symptom, the vertical oozing canker developing along the trunk, is elicited by a particular genetic lineage of the bacterium. Symptoms of hazelnut bacterial blight are visible on leaves and fruits as necrotic lesions, and on woody parts as cankers. A remarkable difference is that affected walnuts drop abundantly, whereas hazelnuts with symptoms do not. DISTRIBUTION Bacterial blight of walnut has a worldwide distribution, wherever Persian (English) walnut is cultivated; the bacterial blight of hazelnut has a more limited distribution, although disease outbreaks are currently more frequently reported. X. arboricola pv. juglandis is regulated almost nowhere, whereas X. arboricola pv. corylina is regulated in most European and Mediterranean Plant Protection Organization (EPPO) countries. EPIDEMIOLOGY AND CONTROL For both pathogens infected nursery material is the main pathway for their introduction and spread into newly cultivated areas; additionally, infected nursery material is the source of primary inoculum. X. arboricola pv. juglandis is also disseminated through pollen. Disease control is achieved through the phytosanitary certification of nursery material (hazelnut), although approved certification schemes are not currently available. Once the disease is present in walnut/hazelnut groves, copper compounds are widely used, mostly in association with dithiocarbamates; where allowed, antibiotics (preferably kasugamycin) are sprayed. The emergence of strains highly resistant to copper currently represents the major threat for effective management of the bacterial blight of walnut.

Abstract
Fire blight is a severe bacterial plant disease that affects important chain-of-value fruit trees such as pear and apple trees. This disease is caused by Erwinia amylovora, a quarantine phytopathogenic bacterium, which, although highly distributed worldwide, still lacks efficient control measures. The green revolution paradigm demands sustainable agriculture practices, for which antimicrobial peptides (AMPs) have recently caught much attention. The goal of this work was to disclose the bioactivity of three peptides mixtures (BP100:RW-BP100, BP100:CA-M, and RW-BP100:CA-M), against three strains of E. amylovora representing distinct genotypes and virulence (LMG 2024, Ea 630 and Ea 680). The three AMPs' mixtures were assayed at eight different equimolar concentrations ranging from 0.25 to 6 μM (1:1). Results showed MIC and MBC values between 2.5 and 4 μM for every AMP mixture and strain. Regarding cell viability, flow cytometry and alamarBlue reduction, showed high reduction (>25%) of viable cells after 30 min of AMP exposure, depending on the peptide mixture and strain assayed. Hypersensitive response in tobacco plants showed that the most efficient AMPs mixtures and concentrations caused low to no reaction of the plant. Altogether, the AMPs mixtures studied are better treatment solutions to control fire blight disease than the same AMPs applied individually.

Abstract
Although technical skills are a prerequisite for success in basketball, little is known about how they develop over time. In this study, we model the trajectories of technical skill development in young basketball players and investigate the effects of training experience, training volume, body composition, maturity status, physical performance, and club characteristics on skill development. A total of 264 male basketballers from five age-cohorts (11 to 15 years of age) were followed consecutively over three years using a mixed-longitudinal design. Technical skills, training experience and volume, basic anthropometrics, body composition, biological maturation and physical performance were assessed bi-annually. A multilevel hierarchical linear model was used for trajectory analysis. Non-linear trends (p < 0.01) were observed in speed shot shooting, control dribble, defensive movement, slalom sprint, and slalom dribble. Being more experienced and physically fitter had a significant (p < 0.05) positive effect on technical skill development; greater fat-free mass negatively affected skills demanding quick running and rapid changes of direction with or without the ball (p < 0.05). Training volume and biological age did not explain differences in technical skill development (p > 0.05). Moreover, belonging to different clubs had no significant influence on the technical skills trajectories of players. Our findings highlight the important role that individual differences play, over and beyond club structure, in developing skills. Findings improve our understanding on how technical skills develop during adolescence through training, growth, and biological maturation.

Abstract
Liquid marbles refer to droplets that are covered with a layer of non-wetting particles. They are observed in nature and have practical significance. These squishy objects bounce, coalesce, break, inflate, and deflate while the liquid does not touch the substrate underneath. Despite the considerable cross-disciplinary interest and value of the research on liquid marbles, a unified framework for describing the mechanics of deflating liquid marbles-as the liquid evaporates-is unavailable. For instance, analytical approaches for modeling the evaporation of liquid marbles exploit empirical parameters that are not based on liquid-particle and particle-particle interactions. Here, we have combined complementary experiments and theory to fill this gap. To unentangle the contributions of particle size, roughness, friction, and chemical make-up, we investigated the evaporation of liquid marbles formed with particles of sizes varying over 7 nm-300 μm and chemical compositions ranging from hydrophilic to superhydrophobic. We demonstrate that the potential final states of evaporating liquid marbles are characterized by one of the following: (I) constant surface area, (II) particle ejection, or (III) multilayering. Based on these insights, we developed an evaporation model for liquid marbles that takes into account their time-dependent shape evolution. The model fits are in excellent agreement with our experimental results. Furthermore, this model and the general framework can provide mechanistic insights into extant literature on the evaporation of liquid marbles. Altogether, these findings advance our fundamental understanding of liquid marbles and should contribute to the rational development of technologies.

Abstract
Purpose
The COVID-19 pandemic has spread rapidly around the world and Portugal is no exception. Positive and negative effects are extremely important in individual's life experiences and in particular in the context of the quarantine, in which it is important to maintain the balance between favorable and unfavorable situations. The purpose of this paper is to study in depth the intensity of the affect during the COVID-19 pandemic in Portugal and to validate a scale of positive and negative affect in the context of quarantine and confinement.
Design/methodology/approach
The methodology used is of a quantitative nature, based on a questionnaire survey to measure the intensity of the affects and to analyze some sociodemographic variables. The sample consists of 726 individuals of age 18 years or older, who were in Portugal during the quarantine of the COVID-19 pandemic.
Findings
The results show that respondents were concerned, anxious, well-disposed and impatient. Exploratory and confirmatory factor analysis applied to affects produced a latent structure with two factors: negative affect and positive affect. The affect scale has adequate convergent and discriminant validity and good internal consistency, with negative affect being experienced by individuals with greater intensity compared to positive affect.
Originality/value
It is hoped that this study contributes to an increase in the scientific knowledge in the field of the affects in the context of delicate situations such as the pandemic COVID-19 so that health professionals can intervene to improve individual’s well-being. This is an important way to provide better health policy that considers in more depth individual wellbeing and emotions during times of crisis. Limitations and suggestions for future research are also stated that highlight the importance of understanding emotional states of individuals during crisis events.

Abstract
Bacteria in the genus Xanthomonas infect a wide range of crops and wild plants, with most species responsible for plant diseases that have a global economic and environmental impact on the seed, plant, and food trade. Infections by Xanthomonas spp. cause a wide variety of non-specific symptoms, making their identification difficult. The coexistence of phylogenetically close strains, but drastically different in their phenotype, poses an added challenge to diagnosis. Data on future climate change scenarios predict an increase in the severity of epidemics and a geographical expansion of pathogens, increasing pressure on plant health services. In this context, the effectiveness of integrated disease management strategies strongly depends on the availability of rapid, sensitive, and specific diagnostic methods. The accumulation of genomic information in recent years has facilitated the identification of new DNA markers, a cornerstone for the development of more sensitive and specific methods. Nevertheless, the challenges that the taxonomic complexity of this genus represents in terms of diagnosis together with the fact that within the same bacterial species, groups of strains may interact with distinct host species demonstrate that there is still a long way to go. In this review, we describe and discuss the current molecular-based methods for the diagnosis and detection of regulated Xanthomonas, taxonomic and diversity studies in Xanthomonas and genomic approaches for molecular diagnosis.

Abstract
Fire blight is a destructive plant disease caused by Erwinia amylovora affecting pome fruit trees, and responsible for large yield declines, long phytosanitary confinements, and high economic losses. In Portugal, the first major fire blight outbreaks occurred in 2010 and 2011, and although later considered eradicated, the emergence of other outbreaks in recent years stressed the need to characterize the E. amylovora populations associated with these outbreaks. In this regard, CRISPR genotyping, assessment of three virulence markers, and semi-quantitative virulence bioassays, were carried out to determine the genotype, and assess the virulence of thirty-six E. amylovora isolates associated with outbreaks occurring between 2010 and 2017 and affecting apple and pear orchards located in the country central-west, known as the main producing region of pome fruits in Portugal. The data gathered reveal that 35 E. amylovora isolates belong to one of the widely-distributed CRISPR genotypes (5-24-38 / D-a-α) regardless the host species, year and region. Ea 680 was the single isolate revealing a new CRISPR genotype due to a novel CR2 spacer located closer to the leader sequence and therefore thought to be recently acquired. Regarding pathogenicity, although dot-blot hybridization assays showed the presence of key virulence factors, namely hrpL (T3SS), hrpN (T3E) and amsG from the amylovoran biosynthesis operon in all E. amylovora isolates studied, pathogenicity bioassays on immature pear slices allowed to distinguish four virulence levels, with most of the isolates revealing an intermediate to severe virulence phenotype. Regardless the clonal population structure of the E. amylovora associated to the outbreaks occurring in Portugal between 2010 and 2017, the different virulence phenotypes, suggests that E. amylovora may have been introduced at different instances into the country. This is the first study regarding E. amylovora in Portugal, and it discloses a novel CRISPR genotype for this bacterium.

Abstract
This study investigated developmental stability, or tracking, in the development of technical skills in youth male basketball players and retrospectively profiled stable and unstable tracking patterns over time. A total of 97 basketball players were tracked bi-annually over 3 consecutive years. Players were divided into two age-categories according to their age at baseline: under-12; and under-14. Technical skills were assessed using the American Alliance for Health, Physical Education, Recreation and Dance test battery. Anthropometric, body composition, biological maturation and physical performance data were collected. Cohen's kappa (κ) was used to estimate tracking. With the exception of defensive movement in the under-12 age-category, tracking was low in all skill tests for both under-12 (0.22 ≤ κ ≤ 0.33) and -14 (0.20 ≤ κ ≤ 0.26) groupings. The overall technical skill showed moderate tracking for under-12 players (κ = 0.47) and low tracking for under-14 players (κ = 0.26). At baseline, players who were consistently more skilled or became more skillful (in the under-12 age-category) over time had a better growth-motor performance profile and most of them were selected to be members of regional teams. In conclusion, tracking of individual skill trajectories was low-to-moderate. Moreover, a better growth-motor performance profile seems crucial to maintain high levels of skill performance over time. It is recommended that basketball coaches track the developmental trajectories of their players to better understand the erratic nature of skill development and help design more effective practice regimes.

Abstract
The recent report of distinct Xanthomonas lineages of Xanthomonas arboricola pv. juglandis and Xanthomonas euroxanthea within the same walnut tree revealed that this consortium of walnut-associated Xanthomonas includes both pathogenic and nonpathogenic strains. As the implications of this co-colonization are still poorly understood, in order to unveil niche-specific adaptations, the genomes of three X. euroxanthea strains (CPBF 367, CPBF 424T, and CPBF 426) and of an X. arboricola pv. juglandis strain (CPBF 427) isolated from a single walnut tree in Loures (Portugal) were sequenced with two different technologies, Illumina and Nanopore, to provide consistent single scaffold chromosomal sequences. General genomic features showed that CPBF 427 has a genome similar to other X. arboricola pv. juglandis strains, regarding its size, number, and content of CDSs, while X. euroxanthea strains show a reduction regarding these features comparatively to X. arboricola pv. juglandis strains. Whole genome comparisons revealed remarkable genomic differences between X. arboricola pv. juglandis and X. euroxanthea strains, which translates into different pathogenicity and virulence features, namely regarding type 3 secretion system and its effectors and other secretory systems, chemotaxis-related proteins, and extracellular enzymes. Altogether, the distinct genomic repertoire of X. euroxanthea may be particularly useful to address pathogenicity emergence and evolution in walnut-associated Xanthomonas.

Abstract
Pseudomonas syringae pv. actinidiae (Psa) is the pathogenic agent responsible for the bacterial canker of kiwifruit (BCK) leading to major losses in kiwifruit productions. No effective treatments and measures have yet been found to control this disease. Despite antimicrobial peptides (AMPs) having been successfully used for the control of several pathogenic bacteria, few studies have focused on the use of AMPs against Psa. In this study, the potential of six AMPs (BP100, RW-BP100, CA-M, 3.1, D4E1, and Dhvar-5) to control Psa was investigated. The minimal inhibitory and bactericidal concentrations (MIC and MBC) were determined and membrane damaging capacity was evaluated by flow cytometry analysis. Among the tested AMPs, the higher inhibitory and bactericidal capacity was observed for BP100 and CA-M with MIC of 3.4 and 3.4-6.2 µM, respectively and MBC 3.4-10 µM for both. Flow cytometry assays suggested a faster membrane permeation for peptide 3.1, in comparison with the other AMPs studied. Peptide mixtures were also tested, disclosing the high efficiency of BP100:3.1 at low concentration to reduce Psa viability. These results highlight the potential interest of AMP mixtures against Psa, and 3.1 as an antimicrobial molecule that can improve other treatments in synergic action.

Abstract
The hostel market urgently needs to reinvent itself and define strategies to increase its revenue, providing safety to its guests during the COVID‐19 pandemic. In the trip's planning, the results show that individuals attribute high levels of importance to cuisine, local wines and to meeting new people. The social networks of the different places to visit are the least utilized means to plan what to do during their stay in Oporto. Static street advertising and leaving the hostel to go outside are much more important to hostel customers. The most notable attractions are the Ribeira and the bridges over the river Douro.

Abstract
OBJECTIVES We sought to determine the relationship between in-hospital mortality and the neutrophil-to-lymphocyte ratio (NLR) in patients with ST-elevation myocardial infarction (STEMI) undergoing with pharmaco-invasive strategy (PIS). BACKGROUND Increased levels of white blood cells have been associated with adverse clinical outcomes in patients with (STEMI). NLR has recently emerged as a potent and more specific prognostic marker in predicting short- and long-term mortalityin patients undergoing primary percutaneous coronary intervention. This association has never been reported in patients managed with PIS. METHODS Between March 2010 and October 2016, 1860 STEMI patients managed with PIS were consecutively included in a dedicated database. The study population was divided into tertiles based on the admission NLR values (lower: <4.0, intermediate: 4.0 to <7.3, and upper: ≥7.3). Co-primary endpoints were in-hospital mortality and MACE (death, non-fatal reinfarction or stent thrombosis). RESULTS Patients in the upper NLR tertile had significantly higher in-hospital mortality (9.0% vs. 4.8% versus. 1.8%, p < 0.001) and MACE (11.6% vs. 8.0% versus 2.9%, p < 0.001) than patients with intermediate or low NLR. By multivariable logistic regression analysis, the upper NLR tertile was an independent predictor of MACE (odds radio [OR] 4.19, 95% confidence interval [95% CI] 2.23-7.88, p < 0.001) and in-hospital mortality [OR 3.32, 95% CI 1.19-9.28, p = 0.02]. CONCLUSION High NLR values were independently associated with in-hospital MACE and death in STEMI patients submitted to a PIS. NLR might be a simple and useful risk stratification tool in this high-risk population.

Abstract
Although successful performance in basketball requires high levels of muscular strength during adolescence, its development is confounded by the effects of normal growth. We examine the timing, intensity and sequence of muscular strength according to biological age (years from peak height velocity (PHV)) and hypothesize that young basketball players attain their peak muscular strength spurts around PHV. A total of 160 adolescent male basketballers, aged 11-15 years, were followed bi-annually over 3 consecutive years. The years from attainment of PHV and peak weight velocity (PWV) were estimated and five muscular strength measures (sit-ups, handgrip, seated medicine ball throw, squat jump and countermovement jump) were aligned to years from PHV in 3-month intervals. Strength velocities were estimated using a non-smooth mathematical model. The mean ages at-PHV and at-PWV were 13.90 ± 1.40 years and 13.90 ± 1.79 years, respectively. Maximal velocity in sit-ups was attained 6 months prior to attainment of PHV (intensity = 10.69 repetitions·year-1), whereas maximal velocity in squat jump occurred 6 months after-PHV (intensity = 3.93 cm·year-1). Handgrip strength, seated medicine ball throw and countermovement jump maximal velocity peaked at-PHV (intensity = 8.47 kgf·year-1, intensity = 0.75 m·year-1, intensity = 5.59 cm·year-1, respectively). In general, maximal velocity spurts did not differ in their timing, with the velocities reaching a peak concurrent with PHV and PWV or within 6 months of its attainment. Basketball coaches, as well as strength and conditioning trainers, should consider individual differences in strength development and be aware of rapid periods of growth in stature when planning and designing muscular strength training regimes.

Abstract
A healthy gastrointestinal microbiota is essential for host fitness, and strongly modulated by host diet. In aquaculture, a current challenge is to feed carnivorous fish with plant-feedstuffs in substitution of fish meal, an unsustainable commodity. Plants have a limited nutritive value due to the presence of non-starch polysaccharides (NSP) which are not metabolized by fish. In this work we assessed the effects of NSP-enriched diets on European seabass gut microbiota and evaluate the selective pressure of plant feedstuffs towards gut microbes with NSP-hydrolytic potential, i.e. capable to convert indigestible dietary constituents in fish metabolites. Triplicate groups of European seabass juveniles were fed a fish meal-based diet (control) or three plant-based diets (SBM, soybean meal; RSM, rapeseed meal; SFM, sunflower meal) for 6 weeks, before recovering intestinal samples for microbiota analysis, using the Illumina's MiSeq platform. Plant-based diets impacted differently digesta and mucosal microbiota. A decrease (p = 0.020) on species richness, accompanied by a decline on the relative abundance of specific phyla such as Acidobacteria (p = 0.030), was observed in digesta samples of SBM and RSM experimental fish, but no effects were seen in mucosa-associated microbiota. Plant-based diets favored the Firmicutes (p = 0.01), in particular the Bacillaceae (p = 0.017) and Clostridiaceae (p = 0.007), two bacterial families known to harbor carbohydrate active enzymes and thus putatively more prone to grow in high NSP environments. Overall, bacterial gut communities of European seabass respond to plant-feedstuffs with adjustments in the presence of transient microorganisms (allochthonous) with carbohydrolytic potential, while maintaining a balanced core (autochthonous) microbiota.

Abstract
We describe a novel species isolated from walnut (Juglans regia) which comprises non-pathogenic and pathogenic strains on walnut. The isolates, obtained from a single ornamental walnut tree showing disease symptoms, grew on yeast extract-dextrose-carbonate agar as mucoid yellow colonies characteristic of Xanthomonas species. Pathogenicity assays showed that while strain CPBF 424T causes disease in walnut, strain CPBF 367 was non-pathogenic on walnut leaves. Biolog GEN III metabolic profiles disclosed some differences between strains CPBF 367 and CPBF 424T and other xanthomonads. Multilocus sequence analysis with seven housekeeping genes (fyuA, gyrB, rpoD, atpD, dnaK, efp, glnA) grouped these strains in a distinct cluster from Xanthomonas arboricola pv. juglandis and closer to Xanthomonas prunicola and Xanthomonas arboricola pv. populi. Average nucleotide identity (ANI) analysis results displayed similarity values below 93 % to X. arboricola strains. Meanwhile ANI and digital DNA-DNA hybridization similarity values were below 89 and 50 % to non-arboricola Xanthomonas strains, respectively, revealing that they do not belong to any previously described Xanthomonas species. Furthermore, the two strains show over 98 % similarity to each other. Genomic analysis shows that strain CPBF 424T harbours a complete type III secretion system and several type III effector proteins, in contrast with strain CPBF 367, shown to be non-pathogenic in plant bioassays. Taking these data altogether, we propose that strains CPBF 367 and CPBF 424T belong to a new species herein named Xanthomonas euroxanthea sp. nov., with CPBF 424T (=LMG 31037T=CCOS 1891T=NCPPB 4675T) as the type strain.

Abstract
In this paper, we outline a systematic testing programme developed to help identify excellence in youth basketball players. We examine the links between biological maturation and training experience with anthropometry, body composition, physical performance, technical and tactical skills from five age-cohorts, and characterize, in detail, facets of their environment. In total, 238 young basketball players aged 11-15 years, clustered into five age-cohorts (11, 12, 13, 14, 15 years) were recruited. We assessed measures across three domains: (1) biological [anthropometry, body composition, biological maturation and physical performance]; (2) skill/game proficiency [technical skills and tactical skills]; and (3) contextual [family support, coach knowledge and competence and club context]. The data were analysed using one-way ANOVAs and multivariate analysis of covariance adjusting for biological maturation and training experience. We report significant differences favouring older basketball players on most biological and skill/game proficiency variables. However, differences between age-cohorts in physical performance and technical skills were mitigated after controlling for the effects of both covariates. In conclusion, our findings highlight the important role of both biological maturation and training experience on youth basketball players' performance and development. We discuss the implications of these findings for research as well as for athletes, parents, coaches and clubs.

Abstract
The key role of bioinformatics in explaining biological phenomena calls for the need to rethink didactic approaches at high school aligned with a new scientific reality. Despite several initiatives to introduce bioinformatics in the classroom, there is still a lack of knowledge on their impact on students' learning gains, engagement, and motivation. In this study, we detail the effects of four bioinformatics laboratories tailored for high school biology classes named "Mining the Genome: Using Bioinformatics Tools in the Classroom to Support Student Discovery of Genes" on literacy, interest, and attitudes on 387 high school students. By exploring these laboratories, students get acquainted with bioinformatics and acknowledge that many bioinformatics tools can be intuitive for beginners. Furthermore, introducing comparative genomics in their learning practices contributed for a better understanding of curricular contents regarding the identification of genes, their regulation, and how to make evolutionary assumptions. Following the intervention, students were able to pinpoint bioinformatics tools required to identify genes in a genomics sequence, and most importantly, they were able to solve genomics-related misconceptions. Overall, students revealed a positive attitude regarding the integration of bioinformatics-based approaches in their learning practices, reinforcing their added value in educational approaches.

Abstract
PurposeThe purpose of this article is to analyze the experiences experienced during the COVID-19 pandemic quarantine, based on an experimental marketing perspective and to validate a scale of experiences for the quarantine context.Design/methodology/approachThe life of a human being is a sum of the experiences that occur in their daily life, from experiences at home, to experiences at work, shopping, holidays and, essentially, with other human beings. However, experiences during the quarantine period became limited to experiences at home. For this, we used a questionnaire survey that analyzes the experiences experienced by individuals. The sample consists of 726 individuals who were in Portugal during the quarantine and confinement period.FindingsThe results show that the exploratory and confirmatory factor analysis produced a structure with four factors that the authors called Sense and Feel, Pandemic Feel, Pandemic Think and Act. The experiences are manifested with greater intensity in the factors Pandemic Think and Sense and Feel. The scale of experiences used showed to have convergent and discriminant validity and adequate internal consistency. It is expected that the present study will contribute to increase scientific knowledge in the behavioral area and in the area of positive psychology in the context of pandemic and confinement situations.Originality/valueThe results achieved become useful for health and marketing professionals, which allow them to define appropriate strategies to better serve the population in order to improve people's health, well-being and quality of life.

Abstract
Management of a population-based screening program circuit depends on characteristics and technical barriers of its application and implementation. The aim is to clarify the information flow, to understand and build a vision of cervical screening information flows in Northern Regional Health Administration Portuguese Public System and to identify the constraints among them. A total of 5 cluster meetings were presented and two expert interviews were conducted allowing to present an informational flow and its constraints. Aims addressed in each interview where based on the expertise of the interviewed. Cervical cancer screening program depends on the use of SiiMA application. This is an information system for the management of population-based screening program which involves mainly 3 entities and allows a longitudinal data collection and study. Three main constraints were reported. The time for updating data for the list of eligible women was bigger than accorded reaching up to 3 months delay. A duplicate of records and discharges in hospital care since the discharge was done both in the hospital system and the SiiMA platform manually in order to the woman re-enter the screening program. Pendencies were seen due to other screening programs running in parallel which had to be sorted out manually in the regional level or by the entity involved. The existence of a screening application is vital for the implementation purposes of a screening program. The lack of integration of the systems increases bureaucratic work, costs and causes time delay. To improve the efficiency of digital transformation ensuring the quality of the process it is necessary to adapt the design of the health informatic systems to the daily practice and its wants and needs. The strategies of forcing an ever-increasing number of frameworks have demonstrated not to be so effective. Therefore, it is a cornerstone to understand these flows in order to improve its structure, intervention and optimization.
Key messages
The existence of a screening digital application is vital but its expanding use arises constraints. Due to the complexity of such programs, a digital strategy is crucial for management and monitoring of the screening at this scale.

Abstract
The mucosal surfaces of fish harbour microbial communities that can act as the first-line of defense against pathogens. Infectious diseases are one of the main constraints to aquaculture growth leading to huge economic losses. Despite their negative impacts on microbial diversity and overall fish health, antibiotics are still the method of choice to treat many such diseases. Here, we use 16 rRNA V4 metataxonomics to study over a 6 week period the dynamics of the gill and skin microbiomes of farmed seabass before, during and after a natural disease outbreak and subsequent antibiotic treatment with oxytetracycline. Photobacterium damselae was identified as the most probable causative agent of disease. Both infection and antibiotic treatment caused significant, although asymmetrical, changes in the microbiome composition of the gills and skin. The most dramatic changes in microbial taxonomic abundance occurred between healthy and diseased fish. Disease led to a decrease in the bacterial core diversity in the skin, whereas in the gills there was both an increase and a shift in core diversity. Oxytetracycline caused a decrease in core diversity in the gill and an increase in the skin. Severe loss of core diversity in fish mucosae demonstrates the disruptive impact of disease and antibiotic treatment on the microbial communities of healthy fish.

Abstract
Xanthomonas arboricola pv. juglandis is the etiologic agent of important walnut (Juglans regia L.) diseases, causing severe fruit drop and high economic losses in walnut production regions. Rapid diagnostics and knowledge of bacterial virulence fitness are key to hinder disease progression and apply timely phytosanitary measures. This work describes an X. arboricola pv. juglandis-specific real-time quantitative PCR (qPCR) using X. arboricola pv. juglandis-specific DNA markers to quantify the bacterial load in infected walnut plant tissues. Method validation was achieved using calibration curves obtained with serial dilutions of X. arboricola pv. juglandis chromosomal DNA and standard curves obtained from walnut samples spiked with X. arboricola pv. juglandis cells. High correlations (R2 > 0.990 and > 0.995) and low limits of detection (35 chromosomes/qPCR reaction and 2.7 CFU/qPCR reaction) were obtained for both markers considering the calibration and standard curves, respectively. Assessment of qPCR repeatability, reproducibility, and specificity allowed us to demonstrate the reliability and consistency of the method. Furthermore, in planta quantification of X. arboricola pv. juglandis bacterial load using infected walnut fruit samples showed a higher detection resolution compared with standard PCR detection. By allowing quantification of virulence fitness of distinct X. arboricola pv. juglandis strains in planta, the proposed qPCR method may contribute to assertive risk assessment of walnut diseases caused by X. arboricola pv. juglandis and ultimately help to improve phytosanitary practices.

Abstract
High-Risk Human papillomavirus (HR-HPV) full genotyping methods have been described as of great potential use in epidemiology and preventive strategies, including cervical cancer screening and HPV vaccination. We characterized the prevalence and distribution of HR-HPV genotypes in cervico-vaginal samples obtained from the Regional Cervical Cancer Screening Program from the Northern Region of Portugal. HR-HPV genotyping was performed using Anyplex™ II HPV-HR Detection kit in 105,458 women enrolled between August 2016 and December 2017. HR-HPVs were detected in 10,665 women (10.2%) with a prevalence ranging from 6.2 to 17.1% depending on age, and from 8.7 to 10.7% depending on geographical location. Multiple infections with two or more HR-HPVs were detected in 2736 (25.7%) of HR-HPV women ranging from 16.5 to 31.0% depending on age. Amongst HR-HPV positive women, HPV-16 (17.5%), HPV-39 (16.7%), HPV-31 (15.0%), HPV-68 (13.2%), HPV-52 (10.7%) and HPV-51 (10.6%) were the most common genotypes in our population, being HPV-16 more frequent in women aged from 30 to 45 years and HPV-39 in 50–65 years. Results also show that HPV16/18 are present in 22.1% and HPV16/18/31/33/45/52/58 in 47.6% of HR-HPV positive women. This is the largest study on HR-HPV genotyping for Cervical Cancer Screening in European populations and provides critical data for program management and vaccine policy. HPV genotyping is important for cervical cancer screening and HPV-vaccine strategies. Largest HR-HPV genotyping Cervical Cancer Screening in European populations. 105,458 women enrolled of which 10,665 (10.2%) were HR-HPV positive. Multiple infections with two or more HR-HPVs were detected in 2736 (25.7%). HPV-16, -39, −31, −68, −52 and −51, in specific rank order, were the most common in our population.

Abstract
The gastrointestinal microbiota plays a critical role on host health and metabolism. This is particularly important in teleost nutrition, because fish do not possess some of the necessary enzymes to cope with the dietary challenges of aquaculture production. A main difficulty within fish nutrition is its dependence on fish meal, an unsustainable commodity and a source of organic pollutants. The most obvious sustainable alternatives to fish meal are plant feedstuffs, but their nutritive value is limited by the presence of high levels of non-starch polysaccharides (NSP), which are not metabolized by fish. The composition of fish-gut microbial communities have been demonstrated to adapt when the host is fed different ingredients. Thus, we hypothesized that a selective pressure of plant-based diets on fish gut microbiota, could be a beneficial strategy for an enrichment of bacteria with a secretome able to mobilize dietary NSP. By targeting bacterial sporulating isolates with diverse carbohydrase activities from the gut of European sea bass, we have obtained isolates with high probiotic potential. By inferring the adaptive fitness to the fish gut and the amenability to industrial processing, we identified the best two candidates to become industrially valuable probiotics. This potential was confirmed in vivo, since one of the select isolates lead to a better growth and feed utilization efficiency in fish fed probiotic-supplemented plant-based diets, thus contributing for sustainable and more cost-effective aquaculture practices.

Abstract
Co-fermentation of garden waste (GW) and food waste (FW) was assessed in a two-stage process coupling hyperthermophilic dark-fermentation and mesophilic anaerobic digestion (AD). In the first stage, biohydrogen production from individual substrates was tested at different volatile solids (VS) concentrations, using a pure culture of Caldicellulosiruptor saccharolyticus as inoculum. FW concentrations (in VS) above 2.9 g L-1 caused a lag phase of 5 days on biohydrogen production. No lag phase was observed for GW concentrations up to 25.6 g L-1. In the co-fermentation experiments, the highest hydrogen yield (46 ± 1 L kg-1) was achieved for GW:FW 90:10% (w/w). In the second stage, a biomethane yield of 682 ± 14 L kg-1 was obtained using the end-products of GW:FW 90:10% co-fermentation. The energy generation predictable from co-fermentation and AD of GW:FW 90:10% is 0.5 MJ kg-1 and 24.4 MJ kg-1, respectively, which represents an interesting alternative for valorisation of wastes produced locally in communities.

Abstract
We report here the draft genome sequence of Xanthomonas sp. strain CPBF 424, isolated from a diseased walnut tree. Multilocus sequence analysis showed that this walnut-pathogenic isolate is located between the nonpathogenic X. arboricola and X. prunicola clusters. These features make this strain a promising reference to disclose new genetic determinants of pathogenesis.

Abstract
Traditional physico-chemical sensors are becoming an obsolete tool for environmental quality assessment. Biomonitoring techniques, such as biological early warning systems present the advantage of being sensitivity, fast, non-invasive and ecologically relevant. In this work, we applied a video tracking system, developed with zebrafish (Danio rerio), to detect microbiological contamination in water. Using the fishs' behavior response, the system was able to detect the presence of a non-pathogenic environmental strain of Escherichia coli, at three different levels of contamination: 600, 1800 and 5000 CFU/100 mL (colony forming units/100 mL). Data was collected during 50 min of exposure and analyzed with the artificial neural networks Self-organizing Map and Multi-layer Perceptron. The behavior of exposed fish was more erratic, with pronounced and rapid changes on movement direction and with significant less exploratory activity. The accuracy, sensitivity and specificity values regarding the detection capability (distinction between presence or absence of contamination) ranged from 89 to 100%. Regarding the classification capability (distinction between experimental conditions), the values ranged from 67 to 89%. This research may be a valuable contribution to improve water monitoring and management strategies, by taking as reference the effects on biosensors, without a biased anthropocentric perspective.

Abstract
Probiotics benefits in fish farming have been usually inferred appraising the effects observed on the host and not through the direct assessment of probiotic dynamics in the host gut microbiota. To overcome this gap, quantitative PCR (qPCR) can be a powerful approach to study the bacterial dynamics in fish gut microbiota. The presented work proposes four B. licheniformis-specific DNA markers and details a qPCR method to track putative probiotics B. licheniformis on fish gut. The four B. licheniformis-specific DNA markers - BL5B (hypothetical protein BL00303), BL8A (serA2), BL13C (rfaB) and BL18A (ligD) - were selected and validated by PCR and multiplex-PCR with 20 B. licheniformis isolates and a broad range of non-target bacteria. To assess the dynamics of B. licheniformis in the digesta of farmed fish, a qPCR was validated using markers BL8A and BL18A and calibration curves obtained for both markers with digesta samples spiked with B. licheniformis cells showed a high correlation (R2 > 0.99) over 6 log units (CFU/reaction), and a limit of detection (LOD) as low as 247 CFUs/reaction. Furthermore, the consistent qPCR repeatability and reproducibility underline the specificity and reliability of the qPCR proposed. Ultimately, the possibility to monitor the dynamics of B. licheniformis probiotics in the gut microbiota of farmed fish might be instrumental to optimize best practices in aquaculture.

Abstract
OBJECTIVES To characterise the test ordering pattern in Northern Portugal and to investigate the influence of context-related factors, analysing the test ordered at the level of geographical groups of family physicians and at the level of different healthcare organisations. DESIGN Cross-sectional study. SETTING Northern Primary Health Care, Portugal. PARTICIPANTS Records about diagnostic and laboratory tests ordered from 2035 family physicians working at the Northern Regional Health Administration, who served approximately 3.5 million Portuguese patients, in 2014. OUTCOMES To determine the 20 most ordered diagnostic and laboratory tests in the Northern Regional Health Administration; to identify the presence and extent of variations in the 20 most ordered diagnostic and laboratory tests between the Groups of Primary Care Centres and between health units; and to study factors that may explain these variations. RESULTS The 20 most ordered diagnostic and laboratory tests almost entirely comprise laboratory tests and account for 70.9% of the total tests requested. We can trace a major pattern of test ordering for haemogram, glucose, lipid profile, creatinine and urinalysis. There was a significant difference (P<0.001) in test orders for all tests between Groups of Primary Care Centres and for all tests, except glycated haemoglobin (P=0.06), between health units. Generally, the Personalised Healthcare Units ordered more than Family Health Units. CONCLUSIONS The results from this study show that the most commonly ordered tests in Portugal are laboratory tests, that there is a tendency for overtesting and that there is a large variability in diagnostic and laboratory test ordering in different geographical and organisational Portuguese primary care practices, suggesting that there may be considerable potential for the rationalisation of test ordering. The existence of Family Health Units seems to be a strong determinant in decreasing test ordering by Portuguese family physicians. Approaches to ensuring more rational testing are needed.

Abstract
Xanthomonas arboricola pv. juglandis (Xaj) is the etiological agent of walnut (Juglans regia L.) bacterial blight (WBB), and has been associated to other walnut emerging diseases, namely brown apical necrosis (BAN) and vertical oozing canker (VOC), altogether severely affecting the walnut production worldwide. Despite the research efforts carried out to disclose Xaj genetic diversity, reliable molecular methods for rapid identification of Xaj isolates and culture-independent detection of Xaj in infected plant samples are still missing. In this work, we propose nine novel specific DNA markers (XAJ1 to XAJ9) selected by dedicated in silico approaches to identify Xaj isolates and detect these bacteria in infected plant material. To confirm the efficacy and specificity of these markers, dot blot hybridization was carried out across a large set of xanthomonads. This analysis, which confirmed the pathovar specificity of these markers, allowed to identify four broad-range markers (XAJ1, XAJ4, XAJ6, and XAJ8) and five narrow-range markers (XAJ2, XAJ3, XAJ5, XAJ7, and XAJ9), originating 12 hybridization patterns (HP1 to HP12). No evident relatedness was observed between these hybridization patterns and the geographic origin from which the isolates were obtained. Interestingly, four isolates that clustered together according the gyrB phylogenetic analysis (CPBF 1507, 1508, 1514, and 1522) presented the same hybridization pattern (HP11), suggesting that these nine markers might be informative to rapidly discriminate and identify different Xaj lineages. Taking into account that a culture-independent detection of Xaj in plant material has never been described, a multiplex PCR was optimized using markers XAJ1, XAJ6, and XAJ8. This triplex PCR, besides confirming the dot blot data for each of the 52 Xaj, was able to detect Xaj in field infected walnut leaves and fruits. Altogether, these nine Xaj-specific markers allow conciliating the specificity of DNA-detection assays with typing resolution, contributing to rapid detection and identification of potential emergent and acutely virulent Xaj genotypes, infer their distribution, disclose the presence of this phytopathogen on potential alternative host species and improve phytosanitary control.
