Abstract
OBJECTIVE We assessed the in vitro activity of delafloxacin and the synergy between cefotaxime and delafloxacin among cefotaxime non-susceptible invasive isolates of Streptococcus pneumoniae (CNSSP). METHODS A total of 30 CNSSP (cefotaxime MIC > 0.5 mg/L) were studied. Serotyping was performed by the Pneumotest-Latex and Quellung reaction. Minimum inhibitory concentrations (MICs) of delafloxacin, levofloxacin, penicillin, cefotaxime, erythromycin and vancomycin were determined by gradient diffusion strips (GDS). Synergistic activity of delafloxacin plus cefotaxime against clinical S. pneumoniae isolates was evaluated by the GDS cross method. RESULTS Delafloxacin showed a higher pneumococcal activity than its comparator levofloxacin (MIC50, 0.004 versus 0.75 mg/L and MIC90, 0.047 versus >32 mg/L). Resistance to delafloxacin was identified in 7/30 (23.3%) isolates, belonging to serotypes 14 and 9V. Synergy between delafloxacin and cefotaxime was detected in 2 strains (serotypes 19A and 9V). Antagonism was not observed. Addition of delafloxacin increased the activity of cefotaxime in all isolates. Delafloxacin susceptibility was restored in 5/7 (71.4%) strains. CONCLUSIONS CNSSP showed a susceptibility to delafloxacin of 76.7%. Synergistic interactions between delafloxacin and cefotaxime were observed in vitro among CNSSP by GDS cross method.

Abstract
BACKGROUND AND OBJECTIVE The prevalence of food allergy (FA) has increased significantly, and the risk of developing anaphylaxis is unpredictable. Thus, discriminating between sensitized patients and those at risk of having a severe reaction is of utmost interest. To explore mast cell activation pattern and T follicular helper (TFH) 13 presence in sensitized and food anaphylaxis patients. METHODS Patients sensitized to Lipid transfer protein (LTP) were classified as anaphylaxis or sensitized depending on the symptoms elicited by LTP-containing food. CD34+-derived MCs from patients and controls were obtained, sensitized with pooled sera, and challenged with Pru p 3 (peach LTP). Degranulation, PGD2, and cytokine/chemokine release were measured. The TFH13 population was examined by flow cytometry in the peripheral blood of all groups. In parallel, LAD2 cells were activated similarly to patients' MCs. RESULTS A distinguishable pattern of mast cell activation was found in anaphylaxis compared to sensitized patients. Robust degranulation, PGD2, and IL-8 and GM-CSF secretion were higher in anaphylaxis, whereas TFG- and CCL2 secretion increased in sensitized patients. Concomitantly, anaphylaxis patients had a larger TFH13 population. MC activation profile was dependent on the sera rather than the MC source. In agreement with that, LAD2 cells reproduce the same pattern as MCs from anaphylactic and sensitized patients. CONCLUSION The distinct profile of mast cell activation allows to discriminate between anaphylaxis and sensitized patients. Pooled sera may determine mast cell activation independently of mast cell origin. Besides, the presence of TFH13 cells in anaphylaxis patients points to an essential role of IgE affinity.

Abstract
Introduction Mucopolysaccharidosis type III (MPS III) or Sanfilippo syndrome is a neurodegenerative disease caused by the accumulation of mucopolysaccharides in the body. As the symptoms are wide ranging, it is a challenge to provide a diagnosis and psychological treatment for affected children. Method The main objective of this study was to describe a form of music therapy treatment applied to three children diagnosed with MPS III. The psychological variables were evaluated by an ad hoc observation recording template, and the physiological variables were measured with a digital meter before and after each session. The perception of the parents was also considered through a semi-structured interview. Results An improvement in the psychological variables was shown in all cases. Changes in the physiological variables were also noted, although they varied according to each child. The parents report some benefit of music therapy and they share difficulty in assessing the extent of benefits of the music therapy. Discussion Findings indicate that music therapy can be a useful form of treatment with multiple benefits for children with conditions such as MPS III or similar conditions. However, further research is needed in this area and in the development of specific ways of evaluating music therapy.

Abstract
Abstract
Study question
What are the molecular pathways overactivated in arrested cleavage stage human embryos?
Summary answer
There is an upregulation of mitochondrial activity and cellular stress-related pathways in arrested cleavage embryos, which is in agreement with the “quiet hypothesis”.
What is known already
mtDNA content decreases during embryo development, however there is a high increase in mtDNA content in arrested cleavage embryos that may correspond to a response to intrinsic or extrinsic factor creating stress. This reasoning would be in agreement with stablished hypothesis showing that a basal metabolism with a moderate-low energy consumption is actually a sign of embryo health, so a viable embryo does not need to use an extra energy to accommodate to the environment (Leese, 2012). The study of the transcriptional profile during human embryo development will give further information about key molecular process involved in in-vitro embryonic competence.
Study design, size, duration
A prospective cohort study was performed with 11 MII oocytes (average age= 22,9 years), 10 non-arrested cleavage embryos (average age= 29,9 years), 5 arrested cleavage embryos (average age= 38,8 years) and 8 blastocysts (average age= 39,1 years). All specimens were warmed and sampled in PCR tubes with 2 μl of suitable reaction buffer for the RNA sequencing protocol.
Participants/materials, setting, methods
Specimens were analyzed by single-cell RNA sequencing (scRNA-seq). Correlation studies, principal component and differential expression analysis were performed with DESeq2 package. Differential gene expression analyses were done using the parametric Wald test, with Benjamini-Hochberg multiple test correction (padj). Finally, Fgsea algorithm was used for enrichment analysis on Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways and Gene ontology (GO) terms.
Main results and the role of chance
We do not observe mitochondria-related activity pathways significantly (P>.05) deregulated between MII oocytes and non-arrested cleavage embryos considering GO and KEGG categories.
When comparing non-arrested cleavage embryos versus blastocysts, we observe several ATP production/consumption and cristae formation-related pathways significantly (P<.05) upregulated in blastocysts compared to non-arrested cleavage embryos considering GO and KEGG categories. This change in activity coincides with the metabolic activation event that occurs in the blastocyst stage.
However, when we analyze arrested cleavage embryos versus non-arrested cleavage embryos, we observe several ATP production related-pathways and mitochondria-related apoptosis pathways significantly (P<.05) upregulated in arrested cleavage embryos compared to non-arrested cleavage embryos considering GO categories. With KEGG categories, we notice a significant (P<.05) upregulation of oxidative phosphorylation in arrested cleavage embryos. On the other hand, when we analyze the differences between arrested cleavage embryos and blastocysts, taking into account the differences related to the change of embryo stage, we do not observe ATP production or consumption-related pathways significantly (P>.05) deregulated considering GO and KEGG categories. Then, human arrested embryos in parallel with the increase in mtDNA content, display an upregulation of mitochondrial activity and cellular stress which is in line with the expected overactive metabolism of non-viable embryos.
Limitations, reasons for caution
All analyzed blastocyst were aneuploid, so we are unable to determine what the results would be with euploid blastocysts. Also, although age can it be ruled out, no differences were observed between mean age from cleavage stage embryos (arrested and non-arrested ones) and blastocyst.
Wider implications of the findings: This study evidences the relation between extreme mtDNA content increase and the identification of the pathways involved in active metabolism and apoptosis in arrested cleavage stage human embryos.

Abstract
An important physical property in environmental samples is particle size distribution. Several processes exist to measure particle diameter, including change in electrical resistance, blocking of light, the fractionation of field flow and laser diffraction (these being the most commonly used). However, their use requires expensive and complex equipment. Therefore, a digital microscopic imaging application (DMIA) method was developed adapting the algorithms used in the helminth egg automatic detector software coupled with a neural network (NN) and Bayesian algorithms. This allowed the determination of particle size distribution in samples of waste activated sludge (WAS), recirculated sludge (RCS), and pre-treated sludge (PTS). The recirculation and electro-oxidation pre-treatment processes showed an effect in increasing the degree of solubilization, decreasing particle size and breakage factor with ranges between 44.29%, and 31.89%. Together with a final NN calibration process, it was possible to compare results. For example, the 90th percentile of equivalent diameter value obtained by the DMIA with the corresponding result for the laser diffraction method. DMIA values: 228.76 μm (WAS), 111.18 μm (RCS), and 84.45 μm (PTS). DMIA processing has advantages in terms of reducing complexity, cost and time, and offers an alternative to the laser diffraction method.

Abstract
Biological detergents are used in research laboratories, to extract or solubilize proteins from cell membranes. In order to evaluate the ability to extract antigens from the bacterial cell surface of the wild Vibrio cholerae strain C7258 and study their immunogenic potential by forming proteoliposomes and cochleate and preserving their immunogenicity, the non-ionic detergent, n-Octylglucoside (n-OG), and the Zwitterionic detergent (3-cholamidopropyl dimethylammonio 1-propanesulfonate; CHAPS) were tested in concentrations between 5 and 15%. The anionic detergent sodium deoxycholate (DOC) was used as a reference. Electrophoretic, immunochemical and electron microscopy techniques have characterized the extracts and their chromatographic fractions. With CHAPS and n-OG detergents in concentrations between 5 and 15%, a higher yield was obtained in the extraction of proteins and lipopolysaccharides (LPS) and other components from the bacterial surface compared to 10% DOC. When using 10% DOC, 15% CHAPS and n-OG between 5 and 15%, stable proteoliposomes were formed, of average size between 82 and 93 nm in diameter, with known proportions of proteins, LPS and other components. In some of the concentrations, liposomes were formed with almost pure proteins. Some cholera outer membrane proteins like the 17 kDa protein, which corresponds to the mannose-sensitive hemagglutinin (MSHA), which mediates the adhesion to the brush border of the small intestine and the outer membrane protein U (OMPU) were identified with monoclonal antibodies (mAbs) and purified. The fundamental components of liposomes, proteins and LPS, retained their molecular weights, when compared with known standards and by processing programs of electrophoretic profiles and their antigenicity, without alterations due to the extraction procedure, as could be verified by immune identification techniques with monoclonal antibodies in the case of LPS, significant antigens in this pathogen. The main purpose of the present work was to show that a new anticholera vaccine formulation based on cochleates, containing selected protein and LPS fraction extracted by detergents, is able to elicit protective high titers of bactericidal antibodies after intragastric immunization in the mice model. The objective was achieved.

Abstract
This paper presents a combination of noninvasive techniques for the study of superimposed painting stages in The Pentecost, a Mexican Colonial panel painting attributed to Baltasar de Echave Orio (1558 - 1619). The application of reflected hyperspectral imaging (HSI) analysis for mapping the distribution of the pigments in the paint surface and the use of ultraviolet (UV) fluorescence photography and X-ray radiography as complementary imaging techniques provide new insights into the making process of the artwork, its manufacturing and conservation state. For a better understanding of the in situ results gathered, we studied a series of paint mock-up samples created following recipes and studio practices from art treatises. The use of spot analytical methods such as fiber optic reflectance spectroscopy (FORS) and X-ray fluorescence spectroscopy (XRF) allowed for a robust identification of the artist's materials.

Abstract
CONTEXT In recent years, the ketogenic diet has gained special relevance as a possible therapeutic alternative to some neurological and chronic diseases. OBJECTIVE The aim of this systematic review was to answer the following question: Does a ketogenic diet improve cognitive skills in patients with Alzheimer's disease, Parkinson's disease, refractory epilepsy, and type 1 glucose deficiency syndrome? To define the research question, the PICOS criteria were used, following the guidelines of the PRISMA method. DATA SOURCES Medline/PubMed, Elsevier Science Direct, Dialnet, EBSCOhost, Mediagraphic, Sage Journals, ProQuest, and Wiley Online Library databases were used. DATA EXTRACTION After applying inclusion and exclusion criteria in accordance with the PRISMA method, a total of 63 entries published between 2004 and 2019 were used. DATA ANALYSIS The records extracted were analyzed from a qualitative approach, so no statistical analysis was carried out. CONCLUSION Although scientific literature on the subject is scarce and there has tended to be a lack of scientific rigor, the studies reviewed confirmed the effectiveness of this diet in improving the cognitive symptomatology of the aforementioned diseases.

Abstract
Avian influenza (AI) is one of the most important viral diseases in poultry, wildlife and humans. Available data indicate that pigeons play a minimum role in the epidemiology of AI. However, a degree of variation exists in the susceptibility of pigeons to highly pathogenic AI viruses (HPAIVs), especially since the emergence of the goose/Guangdong H5 lineage. Here, the pathogenesis of H5N8 HPAIV in comparison with a H7N1 HPAIV and the role of pigeons in the epidemiology of these viruses were evaluated. Local and urban pigeons (Columba livia var. domestica) were intranasally inoculated with 105 ELD50 of A/goose/Spain/IA17CR02699/2017 (H5N8) or A/Chicken/Italy/5093/1999 (H7N1) and monitored during 14 days. Several pigeons inoculated with H5N8 or H7N1 seroconverted. However, clinical signs, mortality, microscopic lesions and viral antigen were only detected in a local pigeon inoculated with H5N8 HPAIV. This pigeon presented prostration and neurological signs that correlated with the presence of large areas of necrosis and widespread AIV antigen in the central nervous system, indicating that the fatal outcome was associated with neurological dysfunction. Viral RNA in swabs was detected in some pigeons inoculated with H7N1 and H5N8, but it was inconsistent, short-term and at low titres. The present study demonstrates that the majority of pigeons were resistant to H5N8 and H7N1 HPAIVs, despite several pigeons developing asymptomatic infections. The limited viral shedding indicates a minimum role of pigeons as amplifiers of HPAIVs, regardless of the viral lineage, and suggests that this species may represent a low risk for environmental contamination. RESEARCH HIGHLIGHTS H7N1 and H5N8 HPAIVs can produce subclinical infections in pigeons. The mortality caused by H5N8 HPAIV in one pigeon was associated with neurological dysfunction. Pigeons represent a low risk for environmental contamination by HPAIVs.

Abstract
Prior to the emergence of the Asian-origin H5 Goose/Guangdong/1/96 (Gs/GD) lineage, highly pathogenic avian influenza viruses (HPAIV) had rarely caused high mortalities in domestic geese. In 2016/2017 European epidemics, H5N8 Gs/GD clade 2.3.4.4 Group B produced an unprecedented number of outbreaks in waterfowl holdings. In this study, the pathogenesis of H5N8 HPAIV in comparison with H7N1 HPAIV, and the role of domestic geese in the epidemiology of these viruses, were evaluated. Local and commercial geese (Anser anser var. domesticus) were intranasally inoculated with 105 ELD50 of A/goose/Spain/IA17CR02699/2017 (H5N8) or A/Chicken/Italy/5093/1999 (H7N1) and monitored daily during 15 days. H5N8 was highly virulent to domestic geese, reaching 100% mortality by 10 days post-infection. Systemic microscopic necrotizing lesions associated with widespread AIV-antigen were detected by IHC techniques, the central nervous system being the most severely affected. High viral loads, measured by qRT-PCR, were present in all samples collected: oral and cloacal swabs, plasma tissues, and moderate levels in pool water. Domestic geese were also susceptible to H7N1 infection, as demonstrated by seroconversion and detection of viral RNA in tissues and plasma in some geese, but all lacked clinical signs. Viral shedding was confirmed in only some geese and was restricted to the oral route, but levels were high and still detected at the end of the study. Overall, H7N1 presents a lower lethality and shedding than H5N8 in geese; however, the viral shedding indicates that these species could play a role in the epidemiology of Gs/GD and other lineages of HPAIVs. RESEARCH HIGHLIGHTS H5N8 Gs/GD clade 2.3.4.4 Group B is highly virulent to domestic geese. The severity of H5N8 is associated with multisystemic replication. H7N1 can infect domestic geese but is avirulent to this species. Domestic geese could play a role in the epidemiology of Gs/GD HPAIVs.

Abstract
Coastal ecosystems, and especially estuaries, are subject to environmental fluctuations that can be amplified by anthropogenic changes. Under a future scenario of global warming, temperature and salinity are likely to be altered and the persistence of macrophyte-dominated ecosystems can be compromised, particularly native or local seagrass communities. This study examined the response of the local seagrass Halophila ovalis to the joint effect of a short-term salinity increase and a transient temperature stress, through two mesocosm experiments. Warming caused a decline in Fv/Fm, TNC content in leaves and plant growth, and increased dark respiration, revealing clear detrimental symptoms of heat stress on plant metabolism and performance. Salinity increase in isolation favoured ramet survival. However, in combination with warming, salinity had a positive effect on Gross Pmax. This suggests that increased salinities might dampen the negative effects of high temperatures, buffering, to some extent, the impact of global warming in temperate estuaries.

Abstract
BACKGROUND/OBJECTIVES The incidence of pancreatic cancer is increasing in developed countries. The incorporation of new therapies, to the first-line treatment of patients with good performance status led to better survival in clinical trials. However, there is a wide variability in their use and some concerns about the treatment of elderly patients who were not included in the clinical trials. METHODS This is a retrospective multicenter study. Data from consecutive patients diagnosed with metastatic pancreatic cancer (mPC) treated with FOLFIRINOX (FFX) or gemcitabine plus nab-paclitaxel (GnP) were analysed to evaluate efficacy (overall survival-OS) and toxicity. RESULTS A total of 119 patients were included. 49.6% were treated with FFX and 50.4% with GNP in first-line. The median OS was 12 months with no statistically significant differences between both regimens (12.7 m for FFX vs 10.2 m for GnP). Elevated Ca 19.9 levels and neutrophil-lymphocyte ratio (NLR) increased the risk of death. Patients who received both regimens in first/second line had a median OS longer than 15 months whichever the sequence. 32 patients (27%) were older than 70-y. 54% patients received a second-line treatment, 56% in the FFX group and 44% in the GnP group. The median OS for patients older than 70 was 9.5 m versus 12.3 m for patients younger than 70. Progression of the disease was the cause of death in 67.6% of the patients. CONCLUSIONS In our setting, the use of FFX and GnP for treating mPC is quite similar, but superiority could not be demonstrated for any of the schemes in the first line. OS was determined by basal levels of Ca 19.9 and NLR. Patients receiving both regimens in first/second line whichever the sequence, exhibited the best survival rates. In our series, elderly patients had poorer survival rates.

Abstract
The common octopus (Octopus vulgaris) is a species of great interest to the aquaculture industry. However, the high mortalities registered during different phases of the octopus lifecycle, particularly the paralarvae stage, present a challenge for commercial aquaculture. Improvement of diet formulation is seen as one way to reduce mortality and improve growth. Molecular growth-markers could help to improve rearing protocols and increase survival and growth performance; therefore, over a hundred orthologous genes related to protein balance and muscle growth in vertebrates were identified for the common octopus and their suitability as molecular markers for growth in octopus paralarvae explored. We successfully amplified 14 of those genes and studied their transcription in paralarvae either fed with artemia, artemia + zoea diets or submitted to a short fasting-refeeding procedure. Paralarvae fed with artemia + zoea had higher growth rates compared to those fed only with artemia, as well as a significant increase in octopus mtor (mtor-L) and hsp90 (hsp90-L) transcription, with both genes also up-regulated during refeeding. Our results suggest that at least mtor-L and hsp90-L are likely linked to somatic growth in octopus paralarvae. Conversely, ckip1-L, crk-L, src-L and srf-L had expression patterns that did not match to periods of growth as would be expected based on similar studies in vertebrates, indicating that further research is needed to understand their function during growth and in a muscle specific context.

Abstract
Background:Musculoskeletal ultrasound (MSUS) is a useful tool to assess disease activity in rheumatoid arthritis (RA) patients. However, it has not yet been established if its use would change treatment decisions within a treat to target strategy or whether it would lead to better outcomes in RA patientsObjectives:Our aim was to determine the impact of MSUS in the clinical management of RA patients and investigate factors associated with subsequent clinical actions by the referring rheumatologistMethods:A prospective analysis of RA patients seen at an MSUS clinic over a 6-month period was undertaken. Pre- and post-US follow-up data (± 3 months) were analyzed. Baseline assessment included clinical features, physical examination and laboratory tests. All MSUS examinations were performed according to EULAR guidelines and using an Esaote MyLab 8 (Esaote, Genoa) with a high frequency (8-15 MHz) transducer. Patients were stratified in groups based on the clinical impact of the MSUS visit: 1) No clinical impact and 2) US findings leading to subsequent clinical action by the referring rheumatologist (including changes in dosages of current rheumatologic treatments, addition/substraction of medications or interventional procedures based on the MSUS results). First, differences between groups were tested using chi-squared and Student-t tests in the univariate analysis. Second, multivariate logistic regression models were employed to investigate factors associated to a change in clinical managementResults:A total of 61 RA patients were included for analysis. Mean age was 61.9± 11.4 years and 51 (83.6%) were female. Disease activity assessment was the most frequent referral reason (43; 70.5%). Overall, MSUS led to a subsequent therapeutic action by the referring rheumatologist in 39 (63.9%) patients, and to a change in the underlying diagnosis and/or in the clinical impression of the chief complaint that generated the referral in 7 (11.5%) patients. Baseline characteristics between both groups are compared in Table 1. In the univariate analysis, the detection of Power Doppler (PD) synovitis/tenosynovitis and 28 swollen joint count were significantly associated with a subsequent clinical action. In the multivariate analysis only PD synovitis/tenosynovitis (OR=3.28; 95%CI 1.06-10.27) remained significantly associated with a change in clinical management (Table 2)Table 1.Baseline characteristics of RA patientsTotal n= 61Change in clinical management n= 39 (63.9%)No change in clinical management n= 22 (36.1%)pAge61.9±11.461.5±12.562.6±9.20.7SexFemale51(83.6%)35(89.7%)16(72.7%)0.09SmokingNon smoker33(54.1%)17(43.6%)16(72.7%)0.08Smoker13(21.3%)11(28.2%)2(9.1%)Former smoker15(24.6%)11(28.2%)13(21.3%)Radiographic erosions29(48.3%)22(57.9%)7(31.8%)0.0528 Tender Joint Count2.3±3.42.7±3.91.6±2.40.228 Swollen Joint Count2±32.6±3.51.1±1.6<0.05ESR (mm/h)28.1±20.626.1±15.531.7±27.40.4CRP (g/L)1±1.51±1.40.9±1.70.7RF (IU/mL)175.8±452.8139.9±249.5243.9±697.40.4ACPA (IU/mL)775.6±998.6619.4±797.11079.9±1,275.90.2US PD synovitis/tenosynovitis37(60.7%)28(71.8%)9(40.9%)<0.05Table 2.Independent factors associated with a change in clinical management based on logistic regression modelpOdds ratio95% C.I.LowerUpper28 Tender Joint Count0.131.240.941.64US PD synovitis/tenosynovitis0.043.281.0610.17Conclusion:The most common indication of MSUS examination in RA patients was disease activity assessment.

Abstract
Background Mycoplasma hyopneumoniae (Mhyo) and Porcine circovirus 2 (PCV-2) are two of the most significant infectious agents causing economic losses in the weaning to slaughter period. Due to their similar vaccination age, the objective of this study was to assess the efficacy of two already existing Mhyo (Hyogen®) and PCV-2 (Circovac®) vaccines when administered separately or combined (RTM) by means of Mhyo or PCV-2 experimental challenges. Results Seven groups of animals were included in the study, being three of them challenged with PCV-2, three with Mhyo and one composed of non-challenged, non-vaccinated pigs. Within each experimental challenge, non-vaccinated (NV) groups were compared with double vaccinated groups using the commercial products separated (VS) or combined (VC). Both vaccinated groups showed significant differences for most parameters measured regarding PCV-2 (serology, percentage of infected animals and viral load in tissues) and Mhyo (serology and gross lesions) when compared to NV groups. VS and VC offered similar results, being only significantly different the PCV-2 antibody values at different time points (higher in the VS group) of the study, although not at the termination day (21 days post-PCV-2 inoculation). Conclusion The present study expands the knowledge on the possibility of using two separate Mhyo and PCV-2 commercial vaccines as a RTM product, which offered equivalent virological, immunological and pathological outcomes as compared to these vaccines when used by separate.

Abstract
AbstractPurposeTo evaluate the effectiveness and tolerability of pregabalin in the management of the discontinuation of benzodiazepines in long-term users.Subjects and methodsWe performed a 12-week, prospective, uncontrolled, non-interventional, and observational study in patients aged 18 years old or above, who met DSM-IV-TR criteria for benzodiazepine dependence without other major psychiatry disorder. Evaluations included the Benzodiazepine Withdrawal Symptom Questionnaire, the Hamilton Anxiety Rating Scale, the Clinical Global Impression Scale, and the Sheehan Disability Scale. A urine drug screen for benzodiazepines was performed at baseline and every 4 weeks thereafter. The primary effectiveness variable was success rate, defined as achievement of benzodiazepine-free status at week 12 according to the urine drug screen.Results and discussionThe mean dose at week 12 was 315 (±166) mg/day. The success rate of the benzodiazepine taper in the primary efficacy population (n = 282) was 52% (95% confidence interval [CI], 46–58). Success rates for women and men were 58% (95% CI, 49–67) and 46% (95% CI, 38–55), respectively. The success rates did not differ according to either the benzodiazepine of abuse or the presence of other substance use disorders. Significant and clinically relevant improvements were observed in withdrawal and anxiety symptoms, as well as in patients’ functioning. At week 12, tolerability was rated as good or excellent by 90% and 83% of the clinicians and patients, respectively.ConclusionOur results suggest that pregabalin is an efficacious and well-tolerated adjunctive treatment for benzodiazepine withdrawal.

Abstract
The first commercial production of sexed semen was at the Cogent company in the United Kingdom. Since then millions of offspring have been born using sexed semen produced by flow cytometry. Sexed semen technology has recently been modernized to what is now known as ULTRA (ST Genetics), completely modifying the technique, medium, and sperm concentration. In field trials using AI, there was no difference between conventional semen (CONV) and ultra-sexed semen at a concentration of 4 million sperm per straw (ULTRA-4M). The combination of invitro embryo production (IVP) and sexed semen technologies has been successful for intensity selection in the cattle industry. The objective of this work was to compare the CONV and ULTRA-4M semen for bovine IVP. The research was carried out in the reproduction laboratory at the Facultad de Estudios Superiores Cuautitlán-Universidad Nacional Autónoma de México (FESC-UNAM). The IVP was performed with a continuous invitro culture (IVC) system. Ovaries (n=213) were collected from a slaughterhouse (Querétaro, México) and transported to the laboratory within 2h (FESC-UNAM) in physiological saline solution (0.9% NaCl) supplemented with penicillin G (100IUmL−1) and streptomycin sulfate (100µgmL−1). For IVP, VITROGEN media were used for IVM, IVF, and IVC. For the IVM, the cumulus-oocyte complexes were selected (only grades 1 and 2) and matured for 24h at 38.5°C in 5% CO2, 95% air, and 100% humidity. Matured oocytes (n=1000) were divided into two groups, the CONV group and the ULTRA-4M group. The IVF process was developed with CONV and ULTRA-4M semen from the same bull (Holstein) at a concentration of 2×106 and 0.5×106 spermmL−1, respectively, for 18h in 38.5°C, 5% CO2, 95% air, and 100% humidity. The presumptive zygotes were denuded by pipetting and left in IVC until Day 7 at 38.5°C, 5% CO2, 5% O2, and 90% N2 at 100% humidity. The cleavage rate, embryos of more than 6 cells, and blastocysts on Day 7 of culture were evaluated. The statistical analysis was carried out with the GLM procedure of the SAS software (version 9.3; SAS Institute Inc.) to evaluate the results of CONV vs. ULTRA-4M (α level=0.05). Percent cleavage for CONV was 72.2%±2.53 and 75.6%±2.53 for ULTRA-4M. For embryos with more than 6 cells, the results for CONV and ULTRA-4M were 59.8%±5.61 and 62.8%±5.61, respectively. The percentage of blastocysts on Day 7 was 37.8%±5.39 for CONV and 43.6%±5.39 for ULTRA-4M. There were no significant differences between the groups (P>0.05) for all variables analysed. Although the number of blastocysts on Day 7 were numerically higher in the ULTRA-4M, differences were not significant. In conclusion, under the conditions of this research the ULTRA-4M had similar results as CONV for bovine IVP.

Abstract
Helminth eggs are among the most important biological contaminants in environmental engineering. They pose a significant health risk associated with poor sanitation, the use of contaminated water for irrigation, and the disposal of excreta or sludge to land. Helminths are parasitic worms transmitted to humans via their eggs, which is the infective stage of their life cycle. They are therefore relevant to public health and environmental fields due to their low infectious dose, their persistence in the environment (up to several years), and their high resistance to conventional disinfection processes. The evaluation of the efficiency of any process of inactivation, through the determination of the viability of these parasites, is fundamental, but the traditional incubation technique requires 20 days to determine both the viability and the infectivity of nematode eggs. However, the present study found that, using an inactivation process at a temperature of 60 °C for 1 hour and incubation at 28 °C and 34 °C, the absence of division of the nucleus of eggs of species from two genera, Ascaris lumbricoides and Toxocara canis, showed them to be inactivated following only 48 hours of incubation. Similar inactivation results were observed using an automatic system as long as the eggs were inactivated. The minimum time required to evaluate the inactivation of nematode eggs through the incubation technique was 48 hours.

Abstract
AIM To describe the findings of implementing May Measurement Month 2017 in the adult Colombian population to raise awareness of the importance of blood pressure measuring, monitoring, and awareness. MATERIALS AND METHODS May Measurement Month is a cross-sectional survey that follows the directives of the International Society of Hypertension and the World Hypertension League, which gathers information on cardiovascular risk factors and blood pressure readings. Its implementation in Colombia was lead by the Santander Ophthalmological Foundation (FOSCAL) and the Latin American Society of Hypertension (LASH) with the support of the Colombian Network for the Prevention of Cardiovascular Diseases and Diabetes (RECARDI). RESULTS Data was collected from 11 departments on 21,797 people, 58.7% of whom were female, with an average age of 40.5±17.7 years. The overall prevalence of high blood pressure (HBP) was 20.8% (self-reported antihypertensive treatment or systolic blood pressure reading [systolic blood pressure≥140mmHg]). Of the total number of hypertensives, 46.5% had systolic blood pressure readings classified as uncontrolled (systolic blood pressure<140mmHg), and 26.4% were unaware that they were hypertensive who, in this report, we consider to be new cases of HBP. CONCLUSION The prevalence of (elevated) blood pressure is high in this young adult population, whose lack of awareness of HBP is also high, and HBP in those aware of their condition is poorly controlled. These results highlight the need to implement effective detection programmes for hypertensive patients and to establish standardised treatments to improve HBP control as a strategy to reduce cardiovascular events.

Abstract
OBJECTIVE Our aim was to evaluate the relationship between the clinical factors of asthma and the use of reliever medication. METHODS We performed an observational cross-sectional study in Spain. The study population comprised patients aged ≥12 years diagnosed with persistent asthma according to the criteria of the Global Initiative for Asthma and receiving maintenance treatment for at least 12 months. Use of reliever medication was classified as low use of reliever medication (LURM) (≤2 times/wk) and high use of reliever medication (HURM) (≥3 times/wk). A variety of clinical variables and patient-reported outcomes (PROs) were recorded (eg, scores on the Asthma Control Questionnaire-5 [ACQ-5] and Test of Adherence to Inhalers [TAI]). RESULTS A total of 406 patients were recruited. Mean (SD) age was 44.3 (17.9) years, and 64% were women. Reliever medication was used ≤2 times/wk in 76.1%. Bivariate analysis showed that HURM was related to smoking habit, unscheduled emergency department visits, hospital admissions, higher doses of inhaled corticosteroid, and night awakenings in the previous 4 weeks (P<.001). The multivariate analysis showed a higher risk of using reliever medication in smokers and former smokers, when the number of night awakenings increased, in cases of self-perception of partially controlled or uncontrolled asthma, or when asthma is uncontrolled according to the ACQ-5. CONCLUSIONS Our study identifies the potential of poor use of reliever medication in the last week as an alarm signal for disease-related parameters such as exacerbations, poor asthma control, and disease severity.

Abstract
Increased plant mortality in temperate seagrass populations has been recently observed after summer heatwaves, although the underlying causes of plant death are yet unknown. The potential energetic constrains resulting from anomalous thermal events could be the reason that triggered seagrass mortality, as demonstrated for benthic invertebrates. To test this hypothesis, the carbon balance of Posidonia oceanica and Cymodocea nodosa plants from contrasting thermal environments was investigated during a simulated heatwave, by analyzing their photosynthetic performance, carbon balance (ratio photosynthesis:respiration), carbohydrates content, growth and mortality. Both species were able to overcome and recover from the thermal stress produced by the six-week exposure to temperatures 4 °C above mean summer levels, albeit plants from cold waters were more sensitive to warming than plants from warm waters as reflected by their inability to maintain their P:R ratio unaltered. The strategies through which plants tend to preserve their energetic status varied depending on the biology of the species and the thermal origin of plants. These included respiratory homeostasis (P. oceanica warm-plants), carbon diversion from growth to respiration (C. nodosa cold-plants) or storage (P. oceanica warm-plants) and changes in biomass allocation (C. nodosa warm-plants). Findings suggest an important geographic heterogeneity in the overall response of Mediterranean seagrasses to warming with potential negative impacts on the functions and services offered by seagrass meadows including among others their capacity for carbon sequestration and carbon export to adjacent ecosystems.

Abstract
Sexual reproduction in predominantly clonal marine plants increases recombination favoring adaptation and enhancing species resilience to environmental change. Recent studies of the seagrass Posidonia oceanica suggest that flowering intensity and frequency are correlated with warming events associated with global climate change, but these studies have been observational without direct experimental support. We used controlled experiments to test if warming can effectively trigger flowering in P. oceanica. A six-week heat wave was simulated under laboratory mesocosm conditions. Heating negatively impacted leaf growth rates, but by the end of the experiment most of the heated plants flowered, while controls plants did not. Heated and control plants were not genetically distinct and flowering intensity was significantly correlated with allelic richness and heterozygosity. This is an unprecedented finding, showing that the response of seagrasses to warming will be more plastic, more complex and potentially more resilient than previously imagined.

Abstract
OBJECTIVE To review the complications of bariatric surgery and their diagnosis with intravenous contrast-enhanced multidetector computed tomography (MDCT). MATERIAL AND METHODS We retrospectively studied all patients who underwent gastric bypass or sleeve gastrectomy at our center during 2013 or 2014. We classified complications into early complications (appearing within 30 days of the intervention) and late complications. RESULTS We reviewed 155 cases and found 24 complications in 22 patients: 16 early complications (7 intraperitoneal hematomas, 5 anastomotic dehiscences, 2 intestinal obstructions, and 2 external hernias) and 8 late complications (3 internal hernias, 3 intestinal perforations, and 2 marginal ulcers). Two patients died. All of these complications were diagnosed with intravenous contrast-enhanced MDCT, except one, which required a barium transit study. CONCLUSION The rate of complications in bariatric surgery is high and the associated mortality is not negligible. Radiologists need to know the normal findings in these patients so they can quickly identify possible complications, most of which can be diagnosed with intravenous contrast-enhanced MDCT.

Abstract
The monthly bulk depositional fluxes of three natural radionuclides (7Be, 210Pb and 40K) were measured at a Mediterranean coastal station (Málaga) over an 11-year period from 2005 to 2015. The mean annual depositional fluxes of 7Be, 210Pb and 40K were 1215, 144 and 67 Bq m-2 year-1 respectively, showing a clear seasonal trend with minimum values recorded during summer and maximum values in winter. The rainfall regime with dry summers allows estimating the dry deposition. Assuming constant dry deposition through each year, 7Be, 210Pb and 40K would account for 12.5, 26.5 and 33% of the bulk fallout respectively which indicates that deposition for 210Pb and 40K are significantly higher than 7Be. The precipitation-normalized enrichment factor alpha used to explain seasonal variations in the depositional fluxes of radionuclides with respect the rainfall, indicates higher depositional fluxes during spring and summer than expected from the amount of rainfall. Despite their different origin, 210Pb and 7Be monthly depositional fluxes have strong correlation. The atmospheric deposition fluxes of 7Be, 210Pb and 40K were controlled mainly by the amount of rainfall (r = 0.89, 0.91 and 0.66 respectively). Moreover, principal component analysis was applied to the datasets and deposition of radionuclides and rainfall in the same component highlighting the importance of the washout mechanism. The mean depositional velocity of aerosols evaluated using 7Be and 210Pb are similar and are compared to other published values.

Abstract
El conocimiento de la anatomía de los tendones flexores es importante para el tratamiento de las lesiones de estas estructuras y su pronóstico. Es imprescindible tener un buen fundamento de las estructuras de los tendones y su relación con la patogénesis de las lesiones y su reparación. El aporte vascular es un punto crítico en la reparación de los tendones flexores. Los tendones flexores extrínsecos se mantienen aplicados sobre el esqueleto de los dedos por un sistema de poleas osteofibrosas que dirigen los tendones en el sistema poliarticular sobre el que actúan. Además, están rodeados de unas vainas sinoviales que permiten su deslizamiento y los nutren, junto con los mesotendones y vínculas.

Abstract
Introducción: Desde que Ueba utilizara por primera vez el injerto óseo vascularizado de peroné en 1973, esta técnica se ha usado con éxito como método de reconstrucción de múltiples tipos de defectos óseos. La correcta vascularización del injerto es clave para su supervivencia. El objetivo de este trabajo es describir la vascularización diafisaria y epifisaria proximal del peroné.Material y método: Se utilizaron 12 especímenes de cadáver criopreservado inyectados con látex negro. Se procedió a su disección, seguida de una técnica de corrosión en solución alcalina para demostrar la distribución de la red vascular del peroné de forma precisa.Resultados: Observamos que el peroné recibe su irrigación sobre todo de una abundante red de vasos periósticos en la diáfisis y en menor medida de la arteria nutricia. Apreciamos que la epífisis proximal presenta entre 2 y 6 ramos recurrentes, procedentes de las arterias tibial anterior y tronco tibioperoneo.Conclusión: El aporte vascular perióstico de la diáfisis del peroné es el mayoritario, siendo limitada la vascularización a través de la arteria nutricia. En la epífisis proximal, la presencia de vasos recurrentes accesorios puede ser de relevancia durante la cirugía.

Abstract
IntroductionObsessive symptomatology can sometimes be worsened when a patient with this personality trait suffers through a period of increased stress.AimTo review articles in PubMed related to how vorticoxetine affects obsessive symptoms in patients with depression.MethodsWe review the case of a 45-year-old male with obsessive personality traits diagnosed of recurrent depression. He was going through a period of stress at work that had worsened his obsessive symptoms (primarily obsessive thoughts). In a previous depressive episode, he was treated with an antidepressant that triggered sexual dysfunction as a side effect. Trying to prevent another antidepressant-induce sexual dysfunction, we decided to use voricoxetine because of its low tendency to interact with the sexual function.ResultsWe started treatment with vorticoxetine reaching a dose of 10 mg/day. Three weeks later the patient reported a decrease in his levels of anxiety, a slight upturn of his mood and a relieve of his obsessive symptoms.ConclusionsVorticoxetine can be considered a good therapeutic option in the treatment of obsessive symptoms in a depressive episode with patients with a history of antidepressant-induce sexual dysfunction.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
INTRODUCTION Up to date the classical therapeutic approach for intralobar sequestrations (IS) has been surgical excision. However, systemic arteries embolization is presented as an alternative, and even constitutes the first line of treatment in some centers. We summarize our experience in selected cases with the aim of preserving the maximum lung parenchyma. MATERIAL AND METHODS Retrospective study of IS who underwent endovascular embolization at our institution between 2013 and 2014. RESULTS Three patients of 12, 14 and 21 months old were treated. Two patients had unilateral IS, one in the left lower lobe (LLL) and the other in the right lower lobe (RLL); the third one had bilateral lesions (a CAM-S complex in the RLL and a IS in the LII). The embolization of the four lesions was performed via right femoral artery. The case with bilateral lesions underwent thoracoscopic lobectomy of the CAM-S 7 months after embolization, finding adherences to the diaphragm. None of the patients had immediate complications and were discharged within 48 hours after embolization. In successive ultrasound and plain radiographs controls, with a follow-up of 6, 18 and 30 months, no complications were found. CONCLUSIONS Systemic vessels embolization is a treatment option for the treatment of IS that avoids surgery, preserves lung parenchyma and does not preclude surgical resection in case of treatment failure or presence of parenchymal lesions. Longer follow-up is needed to determine long-term effectiveness.

Abstract
The objective of this work was to comparatively study the tissue tropism and the associated pathology of 2 autochthonous small ruminant lentivirus (SRLV) field strains using an experimental infection in sheep through the bone marrow. Fifteen male, SRLV-free lambs of the Rasa Aragonesa breed were inoculated with strain 697 (nervous tissue origin, animals A1-A6), with strain 496 (articular origin, animals B1-B6), or with uninfected culture medium (C1-C3). Clinical, serologic, and polymerase chain reaction (PCR) evaluations were performed periodically. Two lambs from each infected group and a control animal were euthanized at 134, 273, and 319 days postinfection. Tissues were analyzed by gross and histopathologic evaluation; immunohistochemistry for CD3, CD4, CD8, CD68, and FoxP3 cell markers; lung morphometric evaluation; and tissue proviral quantification by PCR. All infected animals became positive either by enzyme-linked immunosorbent assay and/or PCR, with group B lambs showing the highest serologic values and more consistently positive PCR reactions. Group A lambs showed representative lung lesions but only mild histopathologic changes in the central nervous system (CNS) or in carpal joints. Contrarily, group B lambs demonstrated intense carpal arthritis and interstitial pneumonia but an absence of lesions in the CNS. Proviral copies in tissues were detected only in group B lambs. Experimental infection with these SRLV strains indicates that strain 496 is more virulent than strain 697 and more prone to induce arthritis, whereas strain 697 is more likely to reproduce encephalitis in Rasa Aragonesa lambs. Host factors as well as viral factors are responsible for the final clinicopathologic picture during SRLV infections.
