RESUMEN
STING-associated vasculopathy with onset in infancy (SAVI) is caused by pathogenic gain-of-function variants in the gene TMEM173 (also named stimulator of interferon genes, STING1). This report details the case of an 11-year-old girl with SAVI who presented with skin-limited symptoms and discusses the phenotype-genotype correlations of the TMEM173 variant present in our patient. Treatment of SAVI focuses on preventing the development or progression of organ damage by reducing systemic inflammation. We summarize the available treatments for this syndrome.
RESUMEN
This work deals with the study of tea stalks from pruning debris using environmental friendly extraction technology to offer new healthy properties. In the manufacturing tea industry, tea trees require to be pruned every year and most of their remains are discarded as a waste with no economic value. Microwave aqueous extraction and pressurized hot water extraction process (autohydrolysis) were used to recover bioactive compounds from the tea branches. Operating at a fixed solid: liquid ratio (1:15), the effect of the maximum heating temperatures from 140 to 220 °C was studied. Liquid extracts were analysed for total phenolic, oligosaccharides, protein, mineral and heavy metals content, as well as for antioxidant capacity. The antitumoral possibilities were also determined for selected samples. The obtained results indicated that both processes could be used as an alternative to recover bioactive compounds from tea wastes, although microwave-assisted extraction allowed saving time when compared with autohydrolysis processing. The temperature exhibited a relevant effect on the total phenolic content and antioxidant capacity, decreasing with the microwave treatment and increasing with the autohydrolysis temperature. The obtained extracts could be adequate for incorporation in food and non-food fields.
RESUMEN
INTRODUCCIÓN: Streptococcus pyogenes (S. pyogenes) es un importante patógeno humano responsable de una gran diversidad de infecciones, algunas de las cuales presentan un carácter severo con elevada morbimortalidad asociada. La proteína M es un determinante de virulencia crítico de este microorganismo. Diferentes estudios comunican un incremento de enfermedad invasora por S. pyogenes (EISP) relacionado con un aumento de serotipos M1 y M3, de reconocida virulencia. El objetivo del trabajo es confirmar el incremento observado de las enfermedades invasoras por S. pyogenes durante 2011-2018, y conocer qué serotipos pudieran estar implicados. MATERIAL Y MÉTODOS: La identificación de los aislados se realizó mediante pruebas fenotípicas convencionales: morfología de las colonias, β-hemólisis, pruebas bioquímicas y detección de antígeno A de Lancefield (DiaMondiaL Strep Kit, DiaMondiaL, Langenhagen, Alemania). La sensibilidad antibiótica se determinó mediante microdilución (Vitek®2 Compact, bioMeriéux, Inc., Durham, NC). La caracterización genotípica incluyó el gen emm y el perfil de superantígenos. RESULTADOS: Entre 2011-2018 se recuperaron 29 S. pyogenes invasores de sangre (16), líquido pleural (9), líquido sinovial (3) y líquido cefalorraquídeo (1). Entre 2011 y 2013, se cuantificó una cepa por año. Entre 2014 y 2018 se aislaron 2, 5, 4, 6 y 9 cepas, respectivamente. Las entidades clínicas más frecuentes fueron bacteriemia y neumonía (10 y 9 casos). Los serotipos mayoritarios fueron M1 (11) y M3 (3), asociados predominantemente a neumonía (6/7 casos) e infección profunda de partes blandas (3/3 casos). CONCLUSIONES: Se constata un incremento de las enfermedad invasora por S. pyogenes en el periodo estudiado resultando mayoritarios, conforme a la bibliografía, los serotipos M1 y M3, los cuales se asocian con neumonía e infección profunda de partes blandas
INTRODUCTION: Streptococcus pyogenes (S. pyogenes) is an important human pathogen that is responsible for a broad range of infections, from uncomplicated to more severe and invasive diseases with high morbidity/mortality. The M protein (emm type) is a critical virulence factor. Several studies have shown an increased incidence of invasive S. pyogenes disease. This was associated with an increase in the prevalence of M1 and M3 types, well-recognised virulent M types. The aim of the present study was to confirm the resurgence of invasive S. pyogenes disease during 2011-2018 and to identify the relationship between specific M types with disease presentation. MATERIAL AND METHODS: Isolates were confirmed using standard techniques: colony morphology, β-haemolysis, biochemical tests, and agglutination with specific antisera (DiaMondiaL Strep Kit, DiaMondiaL, Langenhagen, Germany). The antibiotic sensitivity was performed using microdilution (Vitek®2 Compact, bioMeriéux, Inc., Durham, NC). Molecular analysis included the determination of the emm gene and superantigen profile. RESULTS: A total of 29 invasive isolates were collected (2011-2018) from blood (16), pleural fluid (9), synovial fluid (3), and cerebrospinal fluid (1). One strain per year was isolated between 2011 and 2013, with 2, 5, 4, 6, and 9 strains being isolated between 2014 and 2018, respectively. The most frequent clinical presentations were bacteraemia and pneumonia (10 and 9 cases). The predominant types were M1 (11 isolates) and M3 (3 isolates). A correlation was found between M1 and M3 types, and pneumonia (6/7 cases) and deep soft tissue infections (3/3 cases). CONCLUSIONS: An increased incidence of invasive S. pyogenes disease was observed during the study period, with M1 and M3 types being those most commonly isolated and associated with pneumonia and deep soft tissue infections

We propose a new collider probe for axionlike particles (ALPs), and more generally for pseudo-Goldstone bosons: nonresonant searches that take advantage of the derivative nature of their interactions with Standard Model particles. ALPs can participate as off shell mediators in the s channel of 2â2 scattering processes at colliders like the LHC. We exemplify the power of this novel type of search by deriving new limits on ALP couplings to gauge bosons via the processes ppâZZ, ppâγγ, and ppâjj using run 2 CMS public data, probing previously unexplored areas of the ALP parameter space. In addition, we propose future nonresonant searches involving the ALP coupling to other electroweak bosons and/or the Higgs particle.
RESUMEN
The purpose of this review was to analyse the prevalence of titanium plate removal in orthognathic surgery, as well as the causes of plate removal, and to determine the associated risk factors. A thorough search of the PubMed, Scopus, Embase, and Web of Science databases was conducted. The inclusion criteria were studies of adult patients who underwent orthognathic surgery in which monocortical titanium plates and screws were placed. Of the 325 references identified, 19 were included in the qualitative synthesis and meta-analysis. Overall, 13.4% (95% confidence interval (CI) 9.6-18.3%) of the patients required the removal of at least one titanium plate; 9.7% (95% CI 6.3-14.6%) of the plates placed were removed. The main causes of removal were infection (6.6%), exposed plate (2.6%), thermal sensitivity (2.1%), palpable plate or screw (2.0%), and pain/tenderness (1.9%). Female sex, smoking, and plates placed in the lower jaw were the main risk factors, with odds ratios of 1.5 (95% CI 1.1-2.0), 2.5 (95% CI 1.4-4.2), and 1.8 (95% CI 1.0-3.2), respectively. In no case was a publication bias problem detected. Fixation using titanium plates has a relatively low prevalence of removal. Infection is the main reason for removal. Female sex and smoking, are the main risk factors for removal. Plates placed in the lower jaw is a non-significant risk factor.

White spot disease, caused by infection with white spot syndrome virus (WSSV), is a serious panzootic affecting prawn aquaculture. The disease has spread rapidly around the prawn-culturing regions of the world through a number of previously identified mechanisms. The ability to distinguish and trace strains of WSSV is of great benefit to identify, and then limit, the translocation routes of the disease. Here, we describe a novel genotyping method using 34 short tandem repeat regions of the viral genome concurrently. This technique is highly sensitive to strain differences when compared to previous methods. The efficacy of the described method is demonstrated by testing WSSV isolates from around the globe, showing regional genotypic differences. The differences in the genotypes were used to create a global minimum spanning network, and in most cases the observed relationships were substantiated with verification of transboundary movement. This novel panel of STR markers will provide a valuable epidemiological tool for white spot disease. We have applied this to an outbreak of the disease in Queensland, Australia, that occurred in 2016. While the results indicate that the source of this outbreak currently remains cryptic, the analyses have provided valuable insights with which to further study the origins of the strains involved.

OBJECTIVE: To assess internalizing and externalizing symptoms as risk factors for suicidal behaviour and suicide among adolescents and young adults. METHOD: We conducted a systematic review of articles published until January 2017. We identified 26 883 potential papers; 1701 full-text articles were assessed for eligibility, of which 1479 were excluded because of methodological reasons. Diverse meta-analyses were performed for each group of symptoms. Odds ratios (ORs) and 95% confidence intervals (95% CI) or beta coefficients for categorical variables, and effect size (ES) were calculated for continuous variables. RESULTS: Finally, 41 studies were included, involving participants aged 12-26 years for a systematic review, and 24 articles were included for meta-analysis. The meta-analysis showed that youths with any internalizing (ES = 0.93) or externalizing symptoms (ES = 0.76 and OR = 2.59) were more likely to attempt suicide in future. This effect was also seen in depression symptoms (OR = 6.58 and ES = 1.00), legal problems (OR = 3.36), and anxiety (ES = 0.65). CONCLUSION: Reported internalizing and externalizing symptoms are predictors of suicide behaviour in young people; therefore, the detection and management of these symptoms in young populations could be a crucial strategy for preventing suicidality in this group.

Introducción: el objetivo es analizar el estilo de vida, en función del ejercicio y la dieta, de un grupo de adolescentes de la Comunidad de Madrid, teniendo en cuenta género y patología y su relación con el estado nutricional, la distribución de grasa y la función pulmonar. Metodología: Estudio descriptivo de 207 sujetos que analizó el estilo de vida a partir del nivel de actividad física (AF) y la adherencia a la dieta mediterránea, el estado nutricional y la distribución de grasa, y la salud respiratoria. Resultados: El grupo de no asmáticos fue más activo (p=0,003) y presentó menor ICT (p=0,001) que el grupo de asmáticos. Se encontraron diferencias significativas dentro del grupo sin asma en nivel de AF siendo los varones más activos (p=0,01) y presentando menor índice cintura-talla (ICT) que las mujeres del mismo grupo (p=0,001). Conclusiones: Los adolescentes no asmáticos fueron más activos y presentaron mejor distribución de grasa que los asmáticos
Objectives: objective is to analyze the lifestyle, integrating exercise and diet, of a group of adolescents from the Community of Madrid, taking into account gender and pathology and its relationship with nutritional status, fat distribution and lung function in adolescents with or without asthma. Methods: This was a descriptive study including 207 subjects aged 13.20 ± 0.62 years. Lifestyle was assessed in terms of physical activity (PA) levels, Mediterranean diet, nutritional status, and respiratory health measured through FEV1 (z). Results: In the non-asthma group, boys were more active (p = 0.01) and showed a lower waist-to-height ratio (WHtR) than girls (p = 0.001). Participants without asthma were more active (p = 0.003), and had a better WHtR (p = 0.001) and FEV1 (p = 0.001) than those with asthma. Conclusions: In this Spanish population sample, non-asthmatic adolescents were more active and showed a better nutritional status, fat distribution and respiratory health than their peers with asthma

BackgroundResearch suggests that lesbian, gay and bisexual (LGB) adolescents have a higher risk of suicidal behaviours than their heterosexual peers, but little is known about specific risk factors.AimsTo assess sexual orientation as a risk factor for suicidal behaviours, and to identify other risk factors among LGB adolescents and young adults.MethodA systematic search was made of six databases up to June 2015, including a grey literature search. Population-based longitudinal studies considering non-clinical populations aged 12-26 years and assessing being LGB as a risk factor for suicidal behaviour compared with being heterosexual, or evaluating risk factors for suicidal behaviour within LGB populations, were included. Random effect models were used in meta-analysis.ResultsSexual orientation was significantly associated with suicide attempts in adolescents and youths (OR = 2.26, 95% CI 1.60-3.20). Gay or bisexual men were more likely to report suicide attempts compared with heterosexual men (OR = 2.21, 95% CI 1.21-4.04). Based on two studies, a non-significant positive association was found between depression and suicide attempts in LGB groups.ConclusionsSexual orientation is associated with a higher risk of suicide attempt in young people. Further research is needed to assess completed suicide, and specific risk factors affecting the LGB population.

BACKGROUND: Adolescents with previous self-injurious thoughts and behaviors (SITB) have over 2-fold risk of dying by suicide, higher than older ages. This meta-analysis aims to disentangle the association of each SITB with subsequent suicidal behavior in adolescence/young adulthood, the contribution of each SITB, and the proportion of suicide deaths with no previous suicide attempt. METHODS: We searched 6 databases until June 2015. INCLUSION CRITERIA: 1. Assessment of any previous SITB [a) suicidal thoughts and behaviors (ideation; threat/gesture; plan; attempt); b) non-suicidal thoughts and behaviors (thoughts; threat/gesture; self-injury); c) self-harm] as a risk factor of suicide attempt or suicide death; 2. Case-control or cohort studies; 3. Subjects aged 12-26y. Random effect models, metaregression analyses including mental health and environmental variables, and population attributable risks (PAR)s were estimated. RESULTS: From 23,682 potentially eligible articles, 29 were included in the meta-analysis (1,122,054 individuals). While 68% of all youth suicide deaths had no previous suicide attempt, suicide death was very strongly associated with any previous SITB (OR=22.53, 95%CI: 18.40-27.58). Suicide attempts were also associated with a history of previous SITB (OR=3.48, 95%CI: 2.71-4.43). There were no moderating effects for mental health and environmental features. The PAR of previous SITB to suicide attempts is 26%. LIMITATIONS: There is considerable heterogeneity between the available studies. Due to limitations in the original studies, an over-estimation of the proportion dying at their first attempt cannot be ruled out, since they might have missed unrecognized previous suicide attempts. CONCLUSIONS: Although more than two thirds of suicide deaths in adolescence/young adulthood have occurred with no previous suicidal behavior, previous SITBs have a much higher risk of dying by suicide than previously reported in this age group.

OBJECTIVE: To assess the association and magnitude of the effect of early exposure to different types of interpersonal violence (IPV) with suicide attempt and suicide death in youths and young adults. METHOD: We searched six databases until June 2015. Inclusion criteria were as follows: (1) assessment of any type of IPV as risk factor of suicide attempt or suicide: (i) child maltreatment [childhood physical, sexual, emotional abuse, neglect], (ii) bullying, (iii) dating violence, and (iv) community violence; (2) population-based case-control or cohort studies; and (3) subjects aged 12-26 years. Random models were used for meta-analyses (Reg: CRD42013005775). RESULTS: From 23 682 articles, 29 articles with 143 730 subjects for meta-analyses were included. For victims of any IPV, OR of subsequent suicide attempt was 1.99 (95% CI: 1.73-2.28); for child maltreatment, 2.25 (95% CI: 1.85-2.73); for bullying, 2.39 (95% CI: 1.89-3.01); for dating violence, 1.65 (95% CI: 1.40-1.94); and for community violence, 1.48 (95% CI: 1.16-1.87). Young victims of IPV had an OR of suicide death of 10.57 (95% CI: 4.46-25.07). CONCLUSION: Early exposure to IPV confers a risk of suicide attempts and particularly suicide death in youths and young adults. Future research should address the effectiveness of preventing and detecting early any type of IPV exposure in early ages.

We study the leading effective interactions between the Standard Model fields and a generic singlet CP-odd (pseudo-) Goldstone boson. Two possible frameworks for electroweak symmetry breaking are considered: linear and non-linear. For the latter case, the basis of leading effective operators is determined and compared with that for the linear expansion. Associated phenomenological signals at colliders are explored for both scenarios, deriving new bounds and analyzing future prospects, including LHC and High Luminosity LHC sensitivities. Mono-Z, mono-W, W-photon plus missing energy and on-shell top final states are most promising signals expected in both frameworks. In addition, non-standard Higgs decays and mono-Higgs signatures are especially prominent and expected to be dominant in non-linear realisations.

BACKGROUND: Identifying inflammatory phenotypes is relevant in severe uncontrolled asthma. The aim of this study was to identify the different clinical, inflammatory, functional, and molecular phenotypes in patients with severe asthma and to investigate the potential role of sputum periostin as a biomarker of severe asthma phenotypes. PATIENTS AND METHODS: Sputum induction was performed in 62 patients diagnosed with severe asthma. Skin prick testing, lung function tests, exhaled nitric oxide, hematimetry, and total serum IgE were performed. Periostin was measured in sputum supernatants. RESULTS: Patients with asthma were phenotyped and 80% had late-onset asthma, 50% had fixed airflow obstruction, and 66% showed a Th2-high phenotype. With respect to inflammatory phenotypes, 71% were eosinophilic and 25% mixed granulocytic. Periostin levels were higher in patients with fixed as compared to variable airflow limitation (69.76 vs 43.84 pg/ml, P < 0.05) and in patients with eosinophilic as compared to mixed granulocytic phenotype (61.58 vs 37.31 pg/ml, P < 0.05). There was an inverse correlation between postbronchodilator FEV1 /FVC and periostin levels (-0.276, P < 0.05). CONCLUSION: This study demonstrates the utility of periostin in phenotyping severe asthma. Periostin levels in sputum are associated with persistent airflow limitation in asthma patients with airway eosinophilia despite treatment with high-dose inhaled corticosteroids.

The World Organisation for Animal Health (OIE) Aquatic Animal Health Code recommends that programmes forthe monitoring and surveillance of antimicrobial resistance in microorganisms associated with aquatic animals be initiated by the appropriate authorities. This paper discusses the classes of bacteria to be studied in such programmes and the methods of sample collection to be employed. It also discusses the susceptibility test protocols appropriate for use in such programmes, the interpretive criteria that should be applied to the data they generate and the form in which the output of such programmes should be reported. The authors argue that it is essential that all monitoring and surveillance programmes should employ standardised and internationally harmonised susceptibility test methods to the greatest extent possible. With respect to bacteria capable of infecting aquatic animals, it is recommended that the set of consensus-based standards and guidelines published by the Clinical and Laboratory Standards Institute be adopted as the basis for international harmonisation of test protocols, as they are significantly more developed than any alternatives. It is further recommended that, for the purpose of evaluating antimicrobial resistance trends, such as emerging resistance, the data generated by these protocols should be interpreted by the application of epidemiological cut-off values. However, as yet, internationally agreed cut-off values have been produced for only one species. Thus, for many species, authorities will be obliged to set their own local and laboratory-specific cut-off values. It is recommended that laboratories use a statistical and standardised method of establishing such local cut-off values. Internationally harmonised standard test protocols and interpretive criteria have, to a large extent, been developed to monitor antimicrobial resistance in bacterial species capable of infecting humans. These methods can also be applied to microorganisms capable of infecting humans that are isolated from aquatic animals reared for human consumption or for sale as companion animals.

BACKGROUND/AIMS: Levamisole is an anthelminthic drug with immunomodulatory properties that has been found to be an adulterant of cocaine in the last 2 years. It was present at least in 70% of tainted cocaine in the U.S.A. in 2009. METHODS: We present the case of a 40-year-old patient with a history of weekend cocaine use who consulted for bilateral necrotic lesions in the ears that had appeared 3 days after the last use. RESULTS: Levamisole causes a typical clinical picture characterized by bilateral necrosis of the ears, positive perinuclear antineutrophil cytoplasmic antibodies and laboratory findings of antiphospholipid syndrome, such as anticardiolipin antibodies and/or lupus anticoagulant. CONCLUSION: Dermatologists should be aware of this new entity, which is likely to be more and more frequent due to the increasing use of cocaine. Here we describe a clinical case that is likely to be secondary to levamisole-tainted cocaine and review the literature.

La depresión constituye una amplia gama de problemas de salud mental caracterizados por la ausencia de un afecto positivo (una pérdida de interés y placer en cosas ordinarias y experiencias). Su alta prevalencia hace que se convierta en un grave problema de salud. Para su tratamiento, además del amplio arsenal de medicamentos alopáticos, también contamos con la fitoterapia y, entre sus posibilidades, se encuentra el hipérico (Hypericum perforatum L.). El hipérico posee nivel A de evidencia científica en el tratamiento de la depresión, por lo que su indicación está justificada. El diagrama de flujo construido tiene en consideración los problemas que conlleva la utilización de esta planta medicinal. Al ser un potente inductor del citocromo P450 hace difícil su utilización conjunta con otros fármacos. El manejo de esta droga por parte de los profesionales es complejo, principalmente por las múltiples interacciones y contraindicaciones. El protocolo propuesto puede ser de gran ayuda para la correcta utilización de Hypericum perforatum L (AU)
Depression covers a wide range of mental health problems characterized by the absence of positive feelings and a loss of interest or pleasure in everyday things and experiences. Depression is so widespread that it has become a serious health problem. It can be treated with a broad array of prescribed medicines, as well as herbal medicine -and among the latter treatments we find the extract of St. Johns wort (Hypericum perforatum). St Johns wort is accepted as a treatment for depression with level- A scientific evidence and so its prescription is justified. The proposed flow diagram takes into consideration the problems associated with the use of this drug. Because it is a potent inducer of cytochrome P450, St Johns wort is difficult to use together with other medications. The professional management of its use is complicated, mainly because of the multiple interactions and contraindications. The proposed protocol may be helpful for the correct dispensation of St. Johns wort (AU)
