Diving dinosaurs? Caveats on the use of bone compactness and pFDA for inferring lifestyle. PLoS One 2024; 19:e0298957. [PMID: 38446841 PMCID: PMC10917332 DOI: 10.1371/journal.pone.0298957] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Accepted: 01/31/2024] [Indexed: 03/08/2024] Open
Abstract
The lifestyle of spinosaurid dinosaurs has been a topic of lively debate ever since the unveiling of important new skeletal parts for Spinosaurus aegyptiacus in 2014 and 2020. Disparate lifestyles for this taxon have been proposed in the literature; some have argued that it was semiaquatic to varying degrees, hunting fish from the margins of water bodies, or perhaps while wading or swimming on the surface; others suggest that it was a fully aquatic underwater pursuit predator. The various proposals are based on equally disparate lines of evidence. A recent study by Fabbri and coworkers sought to resolve this matter by applying the statistical method of phylogenetic flexible discriminant analysis to femur and rib bone diameters and a bone microanatomy metric called global bone compactness. From their statistical analyses of datasets based on a wide range of extant and extinct taxa, they concluded that two spinosaurid dinosaurs (S. aegyptiacus, Baryonyx walkeri) were fully submerged "subaqueous foragers," whereas a third spinosaurid (Suchomimus tenerensis) remained a terrestrial predator. We performed a thorough reexamination of the datasets, analyses, and methodological assumptions on which those conclusions were based, which reveals substantial problems in each of these areas. In the datasets of exemplar taxa, we found unsupported categorization of taxon lifestyle, inconsistent inclusion and exclusion of taxa, and inappropriate choice of taxa and independent variables. We also explored the effects of uncontrolled sources of variation in estimates of bone compactness that arise from biological factors and measurement error. We found that the ability to draw quantitative conclusions is limited when taxa are represented by single data points with potentially large intrinsic variability. The results of our analysis of the statistical method show that it has low accuracy when applied to these datasets and that the data distributions do not meet fundamental assumptions of the method. These findings not only invalidate the conclusions of the particular analysis of Fabbri et al. but also have important implications for future quantitative uses of bone compactness and discriminant analysis in paleontology.

Psoriasis Severity, Health-Related Quality of Life, Work Productivity, and Activity Impairments Among Patients With Moderate to Severe Psoriasis Receiving Systemic Treatment: Real-World Data From Clinical Practice in Spain. ACTAS DERMO-SIFILIOGRAFICAS 2024; 115:1-9. [PMID: 37429433 DOI: 10.1016/j.ad.2023.07.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 06/14/2023] [Accepted: 07/04/2023] [Indexed: 07/12/2023] Open
Abstract
BACKGROUND AND OBJECTIVE The treatment of psoriasis should not only focus on skin affectations but also weigh the parameters for health-related quality of life (HRQoL), thereby tackling the concept of cumulative life course impairment (CLCI) and treating the patient from a holistic perspective. The CRYSTAL study aimed to characterize psoriasis with real-word data from Spanish clinical practice in patients with moderate to severe disease who received continuous systemic treatment for at least 24 weeks by using the absolute Psoriasis Area and Severity Index (PASI) score and its correlation to HRQoL. MATERIAL AND METHODS This was a non-interventional, cross-sectional study conducted in 30 centers in Spain, with 301 patients between the ages of 18 and 75 years. The study collected data regarding current treatment and absolute PASI and their relationship to HRQoL using the Dermatology Life Quality Index (DLQI), to activity impairment using the Work Productivity and Activity Impairment (WPAI) questionnaire, and to treatment satisfaction. RESULTS The mean (SD) age was 50.5 (12.5) years, with a duration of disease of 14 (14.1) years. The mean (SD) absolute PASI reported was 2.3 (3.5), with 28.7% of patients presenting with PASI from >1 to ≤3 and 22.6% with PASI>3. Higher PASI scores were associated with higher DLQI (p<0.001) and WPAI scores and lower levels of treatment satisfaction (p<0.001). CONCLUSIONS These data indicate that achieving lower absolute PASI values may correlate not only with better HRQoL but also with better work productivity and treatment satisfaction.

Abstract
BACKGROUND Prediction of the response to a biological treatment in psoriasis patients would allow efficient treatment allocation. OBJECTIVE To identify polymorphisms associated with secukinumab response in psoriasis patients in a daily practice setting. METHODS We studied 180 SNPs in patients with moderate-to-severe plaque psoriasis recruited from 15 Spanish hospitals. Treatment effectiveness was evaluated by absolute PASI ≤3 and ≤1 at 6 and 12 months. Individuals were genotyped using a custom Taqman array. Multiple logistic regression models were generated. Sensitivity, specificity and area under the curve (AUC) were analysed. RESULTS A total of 173 patients were studied at 6 months, (67% achieved absolute PASI ≤ 3 and 65% PASI ≤ 1) and 162 at 12 months (75% achieved absolute PASI ≤ 3 and 64% PASI ≤ 1). Multivariable analysis showed the association of different sets of SNPs with the response to secukinumab. The model of absolute PASI≤3 at 6 months showed best values of sensitivity and specificity. Four SNPs were associated with the capability of achieving absolute PASI ≤ 3 at 6 months. rs1801274 (FCGR2A), rs2431697 (miR-146a) and rs10484554 (HLCw6) were identified as risk factors for failure to achieve absolute PASI≤3, while rs1051738 (PDE4A) was protective. AUC including these genotypes, weight of patients and history of biological therapy was 0.88 (95% CI 0.83-0.94), with a sensitivity of 48.6% and specificity of 95.7% to discriminate between both phenotypes. CONCLUSION We have identified a series of polymorphisms associated with the response to secukinumab capable of predicting the potential response/non-response to this drug in patients with plaque psoriasis.

Abstract
OBJECTIVES To evaluate the achievement of low-density lipoprotein cholesterol (LDLc) goals established by the 2019 European Guidelines for the Management of Dyslipidemias and 2021 Cardiovascular Disease Prevention Guidelines, describe the lipid-lowering treatment received, analyze the achievement of goals according to the lipid-lowering treatment received and study the factors associated with therapeutic success. DESIGN Observational study that included 185 patients of both sexes aged 18 or over undergoing lipid-lowering treatment for primary or secondary prevention, attended at the Lipid Unit. RESULTS 62.1% of the patients had a very high cardiovascular risk (CVR) according to the 2019 guidelines, and 60.5% according to the 2021 guidelines. Of the total cases, 22.7% achieved adequate control of LDLc according to the 2019 guidelines and 20% according to the 2021 guidelines. 47.6% of the patients received very high intensity lipid-lowering treatment, and 14.1% received extremely high intensity lipid-lowering treatment. 76% of subjects with very high CVR on extremely high intensity lipid-lowering treatment achieved the therapeutic objectives of both guides. In the multivariate analysis, factors associated with therapeutic success were the presence of arteriosclerotic cardiovascular disease, the intensity of lipid-lowering treatment, diabetes mellitus, and low to moderate alcohol consumption. CONCLUSIONS Dyslipidemia control is improvable. High or extremely high intensity lipid-lowering treatments can contribute to optimizing control of patients with higher CVR.

Abstract
A predominantly fish-eating diet was envisioned for the sail-backed theropod dinosaur Spinosaurus aegyptiacus when its elongate jaws with subconical teeth were unearthed a century ago in Egypt. Recent discovery of the high-spined tail of that skeleton, however, led to a bolder conjecture that S. aegyptiacus was the first fully aquatic dinosaur. The 'aquatic hypothesis' posits that S. aegyptiacus was a slow quadruped on land but a capable pursuit predator in coastal waters, powered by an expanded tail. We test these functional claims with skeletal and flesh models of S. aegyptiacus. We assembled a CT-based skeletal reconstruction based on the fossils, to which we added internal air and muscle to create a posable flesh model. That model shows that on land S. aegyptiacus was bipedal and in deep water was an unstable, slow-surface swimmer (<1 m/s) too buoyant to dive. Living reptiles with similar spine-supported sails over trunk and tail are used for display rather than aquatic propulsion, and nearly all extant secondary swimmers have reduced limbs and fleshy tail flukes. New fossils also show that Spinosaurus ranged far inland. Two stages are clarified in the evolution of Spinosaurus, which is best understood as a semiaquatic bipedal ambush piscivore that frequented the margins of coastal and inland waterways.

Abstract
Fe(III) complexes are receiving ever-increasing attention as spin crossover (SCO) systems because they are usually air stable, as opposed to Fe(II) complexes, which are prone to oxidation. Here, we present the first systematic study exclusively devoted to assess the accuracy of several exchange-correlation functionals when it comes to predicting the energy gap between the high-spin (S = 5/2) and the low-spin (S = 1/2) states of Fe(III) complexes. Using a dataset of 24 different Fe(III) hexacoordinated complexes, it is demonstrated that the B3LYP* functional is an excellent choice not only for predicting spin-state energy gaps for Fe(III) complexes undergoing spin-transitions but also for discriminating Fe(III) complexes that are either low- or high-spin in the whole range of temperatures. Our benchmark study has led to the identification of a very versatile Fe(III) compound whose SCO properties can be engineered upon changing a single axial ligand. Overall, this work demonstrates that B3LYP* is a reliable functional for screening new spin-crossover systems with tailored properties.

Abstract
Abstract
Pelecanimimus polyodon was discovered in 1993 in the Spanish Barremian fossil site of Las Hoyas, being the first ornithomimosaur described from Europe. So far, there has been no detailed description of the holotype of Pelecanimimus, which is composed of the anterior-half of an articulated skeleton. Here we report a new, detailed, revised and more accurate osteological description of its postcranial skeleton, comparing this new data to information about Ornithomimosauria from the last three decades. This osteological and phylogenetic analysis of Pelecanimimus shows several ornithomimosaur synapomorphies and a unique combination of characters that emend its original diagnosis. Pelecanimimus diverged early in Ornithomimosauria and reveals an enlargement trend of the manus, shared with derived ornithomimosaurians, due to a long metacarpal I and elongated distal phalanges. This evolutionary novelty, and other synapomorphies, has led to the definition of a new clade, Macrocheiriformes, including Pelecanimimus and more derived ornithomimosaurs. Pelecanimimus has the only ossified sternal plates among ornithomimosaurs and the first evidence of uncinate processes in a non-maniraptoran theropod, indicating a convergent appearance of these structures in Coelurosauria. The character combination in an early-diverging ornithomimosaur like Pelecanimimus found in this analysis provides a key step in the evolution of the manus and pectoral girdle in Ornithomimosauria.

Abstract
Psoriatic arthritis is a common type of inflammatory arthritis found in up to 40% of patients with psoriasis. Because skin involvement usually precedes joint involvement, dermatologists play a key role in early detection. Early diagnosis is important for reducing the risk of irreversible structural damage, attenuating the deterioration of physical function, and improving patients' quality of life. This consensus statement was drafted by a group of 9 dermatologists and 1 rheumatologist to provide simple recommendations to help dermatologists screen for psoriatic arthritis in patients with psoriasis. The experts offer consensus-based guidelines that draw on a review of available scientific evidence and on experience acquired in routine clinical practice.

Abstract
BACKGROUND Little has been published on the real-world effectiveness and safety of apremilast in psoriasis. OBJECTIVES To evaluate the effectiveness, safety and drug survival of apremilast at 52 weeks in patients with moderate to severe plaque psoriasis or palmoplantar psoriasis in routine clinical practice. METHODS Retrospective, multicentre study of adult patients with moderate to severe plaque psoriasis or palmoplantar psoriasis treated with apremilast from March 2016 to March 2018. RESULTS We studied 292 patients with plaque psoriasis and 85 patients with palmoplantar psoriasis. The mean (SD) Psoriasis Area and Severity Index (PASI) score was 10.7 (7.0) at baseline and 3.0 (4.2) at 52 weeks. After 12 months of treatment, 73.6% of patients had a PASI score of 3 or less. In terms of relative improvement by week 52, 49.7% of patients achieved PASI-75 (≥75% reduction in PASI score) and 26.5% achieved PASI-90. The mean physician global assessment score for palmoplantar psoriasis fell from 4.2 (5.2) at baseline to 1.3 (1.3) at week 52. Overall drug survival after 1 year of treatment with apremilast was 54.9 %. The main reasons for treatment discontinuation were loss of efficacy (23.9%) and adverse events (15.9%). Almost half of the patients in our series (47%) experienced at least one adverse event. The most common events were gastrointestinal problems. CONCLUSIONS Apremilast may be a suitable alternative for the treatment of moderate to severe psoriasis and palmoplantar psoriasis. Although the drug has a good safety profile, adverse gastrointestinal effects are common.

Abstract
Abstract
Introduction Contemporary cities face multiple socioenvironmental and health challenges that undermine the efforts to promote healthy environments. The 11th goal – Sustainable cities and communities – of United Nations 2030 Agenda for Sustainable Development states that the presence of nature in cities plays a vital role for its sustainability through public urban green spaces (PUGS) accessible and with quality for all.
Objectives This work describes the application of a grid to evaluate the potential of the ecosystems services (ES) of PUGS.
Methodology The grid was applied in 25 PUGS in the city of Porto, divided into 5 clusters of socioeconomic and environmental deprivation (SED), ranging from very high to very low), and is composed by 6 sections with 37 domains assessed: i) identification; ii) description of the activities; iii) activities that take place; iv) assessment of the environment quality; v) existence of infrastructure and facilities; and vi) security. Dimensions iii, iv, v and vi are filled in the grid by a dichotomous answer: No = 0; Yes = 1. All data calculation and statistical analyses were performed using IBM® SPSS® Statistics vs.25.0. The grid was applied in January 2019 and each PUGS visit lasted 20-25 minutes.
Results The highest total score (33) corresponds to 2 parks located in a low and medium SED clusters. The lowest score (9) corresponds to 2 gardens located in a very high and high SED clusters. The most critical dimension assessed of the PUGS has to do with the activities it offers (Median = 2). On the other hand, the dimension with the highest scores relates to the PUGS environmental quality (Median = 8). Regarding results by SED clusters, it is observed that lowest scores, in all assessed domains, are from PUGS located in high and very high SED clusters.
Conclusion This work presents useful information regarding the importance of promoting PUGS with quality and accessible from all, especially to socioeconomic vulnerable groups, which should be the major goal of public policies designers.

Abstract
BACKGROUND AND OBJECTIVE The 4-item Psoriatic arthritis UnclutteRed screening Evaluation (PURE-4) questionnaire is a useful tool for identifying patients with suspected psoriatic arthritis before referring them to a rheumatology department for confirmation. The original English version has good discriminant validity (sensitivity, 85.7%; specificity, 83.6%). We aimed to produce an adapted Spanish version of the PURE-4 for validation and use in Spain. MATERIAL AND METHOD We applied the method recommended by the International Society for Pharmacoeconomic and Outcome Research for the cultural adaptation of patient-centered measurement tools. The phases in the processes involved forward translation, reconciliation, back translation review, harmonization, cognitive debriefing and review, and proofreading. RESULTS We obtained the permission of the author of the original questionnaire. Two native-speaking translators translated the questionnaire into Spanish. Small changes, mainly in the way the items were expressed, were then made in order to reconcile the 2 translations. The questionnaire was then back translated to English and revised to achieve a version equivalent to the original. A Spanish translation derived from the revision was tested for understandability in 7 patients, and the final Spanish version was then produced. During the translation phases, the project manager and a scientific committee made up of a dermatologist and a rheumatologist reviewed the different versions. Team members exchanged information throughout the process, providing for harmonization and the quality control that guaranteed conceptual equivalence. CONCLUSIONS This adaptation of the PURE-4 questionnaire for use in Spain has been the first step toward using it in routine clinical practice. The standardized method we used ensures that the Spanish and the original versions are equivalent.

High browsing skeletal adaptations in Spinophorosaurus reveal an evolutionary innovation in sauropod dinosaurs. Sci Rep 2020; 10:6638.

Abstract
Sauropods were among the most diverse lineages of dinosaurs, with an ample geographic distribution throughout the Mesozoic. This evolutionary success is largely attributed to neck elongation and its impact on feeding efficiency. However, how neck elongation influenced exactly on feeding strategies is subject of debate. The process of mounting a nearly complete virtual skeleton of Spinophorosaurus nigerensis, from the Middle (?) Jurassic of Niger, has revealed several previously unknown osteological adaptations in this taxon. Wedged sacral and posterior dorsal vertebrae cause the presacral column to deflect antero-dorsally. This, together with elongated scapulae and humeri make the anterior region of the skeleton vertically lengthened. Also, elongated prezygapophyseal facets on the cervical vertebrae and a specialized first dorsal vertebra greatly increase the vertical range of motion of the neck. These characters support this early eusauropod as a more capable high browser than more basally branching sauropods. While limb proportions and zygapophyseal facets vary among Eusauropoda, the sacrum retained more than 10° of wedging in all Eusauropoda. This implied a functional constraint for sauropod species which evolved lower browsing feeding strategies: the antero-dorsal sloping caused by the sacrum had to be counteracted with further skeletal modifications, e.g. a ventrally curved mid to anterior presacral spine to hinder the dorsal slope of the whole presacral series caused by the wedged sacrum. This suggests that at least the last common ancestor of Eusauropoda developed high browsing capabilities, partially due to the modified wedged sacrum, likely a potential synapomorphy of the clade and key in the evolutionary history of the group.

Abstract
The functional morphology of sauropod dinosaur long necks has been studied extensively, with virtual approaches yielding results that are difficult to obtain with actual fossils, due to their extreme fragility and size. However, analyses on virtual fossils have been questioned on several of their premises, such as the ability to accurately reconstruct intervertebral tissue with only skeletal data; or whether zygapophyseal overlap can be used to determine the limits of range of motion, since some extreme neck poses in extant giraffes have been claimed not to retain any zygapophyseal overlap. We compared articulation and range of motion in extant giraffes with the exceptionally well-preserved and complete basally branching eusauropod Spinophorosaurus nigerensis from the Middle (?) Jurassic of Niger, under the same virtual paleontology protocols. We examined the articulation and range of motion on grown and young specimens of both Spinophorosaurus and giraffes in order to record any potential changes during ontogeny. Also, the postures of virtual giraffes were compared with previously published data from living animals in the wild. Our analyses show that: (i) articulation of virtual bones in osteologically neutral pose (ONP) does enable accurate prediction of the amount of inter-vertebral space in giraffes and, roughly, in Spinophorosaurus; (ii) even the most extreme neck postures attained by living giraffes in the wild do not require to disarticulate cervical vertebrae; (iii) both living giraffes and Spinophorosaurus have large intervertebral spaces between their cervical centra in early ontogenetical stages, which decrease as ontogeny advances; and (iv) that grown specimens have a greater osteological range of motion in living giraffes and Spinophorosaurus.

Abstract
BACKGROUND Ixekizumab (anti-IL17A) is effective as treatment for moderate-to-severe plaque psoriasis, but real-life data on effectiveness and safety are currently very limited. OBJECTIVE To evaluate the efficacy and safety of ixekizumab in a cohort of real-life plaque psoriasis patients. METHODS Retrospective chart review of 100 patients with moderate-to-severe plaque psoriasis treated with ixekizumab at seven Spanish dermatological centres. RESULTS According to the as observed analysis, the percentage of patients achieving a 75% and 90% of reduction from the baseline score of Psoriasis Area and Severity Index (PASI) was 87.5%-50.0% at week 12-16; 88.3%-58.4% at week 24 and 82.9%-58.5% at week 52, respectively. The mean ± standard deviation (SD) score of PASI at baseline was 12.9 ± 9.2, and it declined rapidly after ixekizumab administration to 1.9 ± 4.0 (P < 0.001) at week 12-16 and was maintained at 1.7 ± 4.1 and 1.8 ± 2.9 at week 24 and 52, respectively. Ixekizumab response was not affected by clinical variables like body mass index, disease duration or the presence of psoriatic arthritis. However, the bio-naive group showed significantly higher PASI 75 response rate at week 12-16 compared to patients previously exposed to biologic agents (P = 0.037). Twenty-six (26%) patients experienced adverse events (AEs) during the follow-up period, being most of them of mild-to-moderate intensity. The most common AE was local reaction at the site of injection (14/26; 53.8%). At the end of the observational period, 15 (15%) patients discontinued ixekizumab treatment due to limited clinical improvement (n = 11), adverse events (n = 3) or lost to follow-up (n = 1) within a mean ± SD time of 6.0 ± 3.9 months. CONCLUSION The present study illustrates the initial experience with ixekizumab in real-world clinical practice confirming its usefulness and safety in the management of plaque psoriasis patients.

Abstract
INTRODUCTION AND OBJECTIVES The Early Arthritis for Psoriatic patients (EARP) questionnaire is a screening tool for psoriatic arthritis. The original Italian version has good measurement properties but the EARP required translation and adaptation for use in Spain. This article describes the cultural adaptation process as a step prior to validation. MATERIAL AND METHODS We used the principles of good practice for the cross-cultural adaptation of patient-reported outcomes measurement established by the International Society Pharmacoeconomics and Outcome Research. The steps in this process were preparation, forward translation, reconciliation, back-translation and review, harmonization, cognitive debriefing and review, and proofreading. During preparation the developers of the original questionnaire were asked for their permission to adapt the EARP for use in Spain and to act as consultants during the process. RESULTS The original questionnaire was translated into Spanish by native Spanish translators, who made slight changes that were approved by the questionnaire's developers. The Spanish version was then back-translated into Italian; that version was reviewed to confirm equivalence with the original Italian text. The reconciled Spanish EARP was then tested for comprehensibility and interpretation in a group of 35 patients. All the patients answered all items without making additional comments. CONCLUSION This cultural adaptation of the EARP questionnaire for Spanish populations is the first step towards its later use in routine clinical practice. The application of a cross-cultural adaptation method ensured equivalence between the original and Spanish versions of the EARP. The Spanish questionnaire will be validated in a second stage.

The internal anatomy of titanosaur osteoderms from the Upper Cretaceous of Spain is compatible with a role in oogenesis. Sci Rep 2017; 7:42035.

Abstract
Dermal armor is one of the most intriguing features of some titanosaurs, the only sauropod dinosaurs that bore osteoderms. Some studies have revealed cavities of varying sizes inside some titanosaur osteoderms, interpreted as the result of bone remodeling for mineral mobilization. Several hypotheses have been proposed to explain the need for mineral mobilization in titanosaurs. However, rejecting those hypotheses was difficult with hitherto available evidence. The Upper Cretaceous site of Lo Hueco (Cuenca; Spain) has yielded one of the largest titanosaur osteoderm sets available. Observation of pre-existing breakages in the fossils and CT-scanning have revealed a predominant internal channel network for bulb and root osteoderms: most had a very compact spongy bone core, perfused by large longitudinal branching neurovascular canals. Only few osteoderms from the same bed, which was deposited in a single and short event, had areas with low-density spongy bone. This void-like low-density bone is always associated with internal channels. It is also present in osteoderms of different sizes. This scenario is best explained when considering that Lo Hueco titanosaurs might have used their osteoderms as a source of calcium that was mobilized during oogenesis, although other hypotheses cannot be completely ruled out.

Abstract
The Strategic Implementation Plan of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) proposed six Action Groups. After almost three years of activity, many achievements have been obtained through commitments or collaborative work of the Action Groups. However, they have often worked in silos and, consequently, synergies between Action Groups have been proposed to strengthen the triple win of the EIP on AHA. The paper presents the methodology and current status of the Task Force on EIP on AHA synergies. Synergies are in line with the Action Groups' new Renovated Action Plan (2016-2018) to ensure that their future objectives are coherent and fully connected. The outcomes and impact of synergies are using the Monitoring and Assessment Framework for the EIP on AHA (MAFEIP). Eight proposals for synergies have been approved by the Task Force: Five cross-cutting synergies which can be used for all current and future synergies as they consider overarching domains (appropriate polypharmacy, citizen empowerment, teaching and coaching on AHA, deployment of synergies to EU regions, Responsible Research and Innovation), and three cross-cutting synergies focussing on current Action Group activities (falls, frailty, integrated care and chronic respiratory diseases).

Abstract
Biomonitoring is an important tool for the assessment of the quality and functions of ecosystems, providing information about the pollutants present and the direct effects that they exert on organisms. Biomonitoring relies upon the quantification of variables that can be biochemical, genetic, morphological and physiological changes. Such variables are designated as biomarkers, and multiple biomarkers are usually determined simultaneously in order to have a more integrated analysis and information about sublethal early effects of contaminants. In this work, we quantified biomarkers, associated with oxidative stress (glutathione-S-transferases GSTs, and catalase CAT, activities; levels of peroxidative alterations, by the thiobarbituric acid reactive substances assay, TBARS) and neurotoxicity (acetylcholinesterase activity, AChE) in the polychaete Hediste diversicolor. Organisms were collected at three distinct estuaries, Ria de Aveiro (Laranjo and São Jacinto), Douro River (São Paio, Afurada, and Ribeira da Granja), both impacted by human activities, and Minho River (Seixas), which has been used as a reference site. Obtained data showed the occurrence of anti-oxidant responses, in most samples from contaminated sites, which was not followed however by the occurrence of oxidative damage in organisms from Ria de Aveiro. None of the analyzed organisms had significant impairment of cholinesterasic activity, suggesting the absence of a prior exposure to neurotoxic compounds. In fact, organisms collected at Ria de Aveiro had largely increased AChE activity, suggesting an uncommon paradoxical biological response that is further discussed.

Abstract
The present study examined the in vivo capacity of diHDA-glycerol, a new chemically defined compound that we synthesized, to enhance nonspecific resistance of Itys mice to a virulent Salmonella typhimurium challenge (>LD50). This compound derives from (E)-10 hydroxy-2 decenoic acid (10-HDA), a fatty acid isolated from Royal Jelly. Bacterial growth rate within the spleen, interferon-gamma (IFN-γ), interleukin-10 (IL-10), and nitric oxide (NO) levels were measured in splenocyte cultures from diHDA-glycerol-pretreated mice or saline infected controls, at various time intervals after infectious challenge. Repeated administration of diHDA-glycerol before bacterial inoculation resulted in increased bacterial clearance from the spleen, starting in the second week of infection, whereas in control mice, bacterial proliferation led to death beyond day 13 after challenge. In addition, spleen cells from infected mice produced elevated levels of IFN-γ but failed to produce IL-10. In contrast, on the second week post challenge, the time course of cytokine responses was modified by the pretreatment. Spleen cells from diHDA-glycerol pretreated mice exhibited significantly lower levels of IFN-γ and significantlty higher levels of the anti-inflammatory cytokine IL-10, when compared with those in infected controls. Furthermore, on the second week post challenge, the restored functional capacity of splenocytes to produce nitric oxide (NO) was apparently linked with diHDA-glycerol pretreatment. These results suggest that diHDA-glycerol accelerates some macrophage functions resulting in a more adequate modulation of the balance of inflammatory mediators and consequently, in an enhanced host defense against Salmonella infection.

Abstract
Although Mycobacterium bovis infection is commonly reported in red deer (Cervus elaphus), potential differences in the effects of infection on male and female animals in terms of body condition and clinical biochemistry have not been reported. Between November 2000 and January 2006, serum and biometrical data were collected post-mortem from 88 red deer. M. bovis-infected deer, particularly males, were typically older, heavier and in poorer body condition than uninfected animals. Serum triglyceride, cholesterol (both particularly in males) and total protein concentrations were lower, whereas serum creatinine (more evident in females), and immunoglobulin G and M concentrations were higher in the infected deer. These sex-related differences in the response to M. bovis infection in red deer should be considered when undertaking epidemiological assessments and designing disease control strategies as they may reflect differing roles of male and female animals as potential reservoirs or disseminators of disease.

Abstract
Phototherapy, classic systemic treatments (methotrexate, acitretin, and ciclosporin), and biologic agents (etanercept, infliximab, adalimumab, and ustekinumab) constitute a broad therapeutic arsenal that increases the likelihood of achieving control of severe and extensive disease in patients with psoriasis. Acitretin continues to be a very valuable tool in both monotherapy, in which it is combined with other systemic treatments (classic or biologic), and in sequential therapy. Thanks to its lack of a direct immunosuppressive effect and its ability to achieve a long-term response, acitretin has an important role in the treatment of psoriasis, although this has not always been acknowledged in relevant treatment guidelines. We present consensus guidelines for the use of acitretin in psoriasis drawn up by the Psoriasis Group of the Spanish Academy of Dermatology and Venereology. These guidelines provide a detailed account of acitretin, including pharmacological properties, indications and contraindications, adverse effects, and factors that should be taken into account to enhance the safe use of this drug. They also propose treatment strategies for use in routine clinical practice. The overall aim of these guidelines is to define the criteria for the use and management of acetretin in psoriasis.

Abstract
BACKGROUND Although national guidelines on biologic agents for treating moderate to severe psoriasis in adults have been published in several countries, increased knowledge on the practical aspects of their implementation is required. OBJECTIVE The objective of this study was to survey Spanish dermatologists to determine their expert opinions on practical aspects of psoriasis treatment with biologics. MATERIALS AND METHODS An online survey was sent to 309 dermatologists who belong to the Spanish Psoriasis Group and/or the Spanish Academy of Dermatology and Venereology (AEDV). The questionnaire was designed specifically for the study and included items on various aspects of the treatment of psoriasis in clinical practice. Six coordinators in different geographic areas worked together to write the final expert report. RESULTS The response rate was 97% (300 returned questionnaires). The biologics preferred, or considered to be the best option (median score 4 out of 4 points) by respondents, were infliximab for its short-term efficacy (74% of the respondents) and rapid onset of action (78%); ustekinumab for convenience of administration (73%); and etanercept because of its suitability for cyclic treatment (71%), safety in long-term use (72%), and the possibility of temporary interruption of treatment under certain circumstances (76%). Etanercept was assigned the highest evaluations for safety and expected survival time (scored 5 on each item by 49% and 33% of the respondents, respectively). Thirty percent of the respondents considered that clinical guidelines contain important information for therapeutic management of psoriasis. CONCLUSIONS This study provides a unique perspective on the opinions of a large sample of dermatologists as regards current treatment of psoriasis with biologics in Spain.
