    Background: The incidence of cutaneous squamous cell carcinoma (cSCC) is increasing over the years. Risk factors for local recurrence and metastasis have been widely studied in highly sun-exposed areas of the body but less data exist about less sun-exposed ones. The main objective of this study is to compare the risk of local recurrence and metastases in patients with cSCC in highly sun-exposed areas compared to cSCC in less sun-exposed areas. Material and methods: A retrospective observational study was carried out, including 558 patients with histopathologically confirmed cSCC at the Reina Sofía University Hospital (HURS), Córdoba, during the period from 1 January 2017 to 31 December 2020. Demographic, clinical and anatomopathological data were collected. Results: Local recurrence occurs more often in highly sun-exposed areas (15.8%) compared to less sun-exposed ones (7.4%) (p < 0.05). However, no differences in the rate of metastases in both groups were found. The presence of affected surgical margins and tumor thickness were identified as independent risk factors for cSCC in low sun-exposure areas. Conclusions: cSCC located in anatomical areas of high sun exposure presented a greater risk of developing local recurrence in our population, which could suggest that these tumors have worse prognosis than those that lie in areas that do not receive chronic sun exposure.

    Relationships between abstract features and methodological quality explained variations of social media activity derived from systematic reviews about psoriasis interventions
    (Elsevier, 2018-05-18) Ruano, J; Aguilar-Luque, Macarena; Isla Tejera, B; Alcalde-Mellado, P; Gay-Mimbrera, J; Hernández Romero, JL; Sanz-Cabanillas, JL; Maestre-López, B; González-Padilla, M; Carmona-Fernández, PJ; García-Gómez, Francisco Javier; Velez Garcia-Nieto, Antonio; [Ruano,J; Aguilar-Luque,M; Isla-Tejera,B; Alcalde-Mellado,P; Gay-Mimbrera,J; Hernández-Romero,JL; Sanz-Cabanillas,JL; Maestre-López,B; González-Padilla,M; Carmona-Fernández,PJ; García-Gómez,Francisco J; Velez Garcia-Nieto,A] IMIBIC/Reina Sofia University Hospital/University of Cordoba, 14004 Cordoba, Spain
    Objectives: The aim of this study was to describe the relationship among abstract structure, readability, and completeness, and how these features may influence social media activity and bibliometric results, considering systematic reviews (SRs) about interventions in psoriasis classified by methodological quality. Study Design and Setting: Systematic literature searches about psoriasis interventions were undertaken on relevant databases. For each review, methodological quality was evaluated using the assessing the methodological quality of systematic reviews tool. Abstract extension, structure, readability, and quality and completeness of reporting were analyzed. Social media activity, which consider Twitter and Facebook mention counts, as well as Mendeley readers and Google scholar citations were obtained for each article. Analyses were conducted to describe any potential influence of abstract characteristics on review’s social media diffusion. Results: We classified 139 intervention SRs as displaying high/moderate/low methodological quality. We observed that abstract readability of SRs has been maintained high for last 20 years, although there are some differences based on their methodological quality. Free format abstracts were most sensitive to the increase of text readability as compared with more structured abstracts (Introduction, Methods, Results, and Discussion or eight headings), yielding opposite effects on their quality and completeness depending on the methodological quality: a worsening in low quality reviews and an improvement in those of high quality. Both readability indices and preferred reporting items of systematic reviews and meta-analyses for Abstract total scores showed an inverse relationship with social media activity and bibliometric results in high methodological quality reviews but not in those of lower quality. Conclusion: Our results suggest that increasing abstract readability must be specially considered when writing free format summaries of high-quality reviews because this fact correlates with an improvement of their completeness and quality, and this may help to achieve broader social media visibility and article usage.

    Prognostic Outcomes of Cutaneous Squamous Cell Carcinoma in Solid Organ Transplant Recipients: A Retrospective Comparative Cohort Study
    (MDPI, 2023-12-11) Salido-Vallejo, Rafael; Escribano-Castillo, Lourdes; Antoñanzas, Javier; Roldán-Córdoba, Claudia; Velez Garcia-Nieto, Antonio; Aguado-Gil, Leyre; [Salido-Vallejo,R; Antoñanzas,J; Aguado-Gil,L] Department of Dermatology, University Clinic of Navarra, 31008 Pamplona, Spain.

    Introduction: Cutaneous squamous cell carcinoma (cSCC) is the second most common cutaneous neoplasm, and its incidence is on the rise. While most cSCCs have an excellent prognosis, certain risk factors, especially immunosuppression, have been associated with higher rates of local recurrence (LR), metastasis, and poor prognosis. This study aims to assess the risk factors for LR and metastasis development in cSCC among solid organ transplant recipients (SOTRs) and compare these rates with those in immunocompetent patients. Materials and Methods: A retrospective observational study included cSCC cases from the University Hospital Reina Sofía in Córdoba, Spain, between 2002 and 2019. Demographic, clinical, and histopathological data were collected. Local recurrence and metastasis rates were analyzed, along with progression-free survival. Univariate analyses were performed to identify prognostic factors in SOTRs. Results: Among 849 cSCC cases, we found higher rates of local recurrence and metastasis in tumors developed by SOTRs compared to those in immunocompetent individuals. However, no significant differences in local recurrence, metastasis, or progression-free survival were observed between the two groups. Risk factors for adverse outcomes in SOTRs included tumor size > 2 cm, depth > 4 mm, and a higher Clark level. A total of 34.4% of SOTRs developed a second primary cSCC during the follow-up. Conclusions: In our study, cSCCs in SOTRs did not exhibit statistically significant differences in the rates of adverse outcomes compared to immunocompetent patients. The prognosis of cSCCs in SOTRs may be more related to other tumor-dependent risk factors than to the immunosuppression status itself. Future studies are needed to refine risk stratification and follow-up protocols to ensure the optimal management of high-risk cSCC cases, particularly among immunosuppressed patients.

    Combined daylight and conventional photodynamic therapy with 5- aminolaevulinic acid nanoemulsion (BF-200 ALA) for actinic keratosis of the face and scalp: a new and efficient approach
    (Springer, 2019-12-14) Salido-Vallejo, Rafael; Jiménez-Nájar, F; Garnacho-Sucedo, G; Velez Garcia-Nieto, Antonio; [Salido‑Vallejo,R; Garnacho-Sucedo,G; Velez Garcia-Nieto,A] Department of Dermatology, Reina Sofía University Hospital, Avd. Menéndez Pidal,Córdoba, Spain. [Jiménez-Nájar,F] School of Medicine, University of Córdoba, Córdoba, Spain.
    Conventional photodynamic therapy (cPDT) using red light is considered one of the most effective therapy option for the treatment of actinic keratosis (AK). The main disadvantage of cPDT is the pain experienced by the patients during illumination. Daylight PDT (dPDT) represents an effective and painless alternative. It can be speculated that a combination of both regimes combines their benefits. To compare the combination of cPDT and dPDT (combPDT) to dPDT alone in terms of effectiveness and safety. The study was developed as a single-centre, intraindividual, retrospective study. Each patient received one dPDT and a combPDT session with BF-200 ALA. Primary effectiveness endpoints included the reduction in the number of basal AK, percentage of patients with complete response (CR) and partial response (PR). Safety parameters evaluated were local skin response (LSR) and visual analogue scale (VAS). A total of 19 patients with 264 AK were evaluated 12 weeks after both PDT modalities. The area treated with combPDT showed a reduction in the number of AK lesions (82.7%) when compared to the dPDT-treated area (56.8%). Higher rates of CR (31.6% vs 15.8) and PR (63.2% vs 26.3%) were achieved in combPDT fields. Areas treated with combPDT showed enhanced local skin reactions (LSR) in comparison with dPDT-treated areas (6.4 vs.4.4, respectively). In combPDT-treated patients a moderate increase of the pain during illumination was observed when compared to dPDT (VAS: 3.4 vs 0.6). This study reports the first data set on the benefit of a direct combination of daylight and subsequent conventional red light illumination (combPDT) with BF-200 ALA. The combination approach achieved a significant increase in clearance rates of AK lesions, while pain was perceived as mild to moderate during red light illumination.

    The outcome of acute myeloid leukemia patients aged 70 years or older is poor. Defining the best treatment option remains controversial especially when choosing between intensive chemotherapy and hypomethylating agents. We set up a multicentric European database collecting data of 3 700 newly diagnosed acute myeloid leukemia patients ≥70 years. The primary objective was to compare overall survival in patients selected for intensive chemotherapy (n = 1199) or hypomethylating agents (n = 1073). With a median follow-up of 49.5 months, the median overall survival was 10.9 (95% CI: 9.7-11.6) and 9.2 months (95% CI: 8.3-10.2) with chemotherapy and hypomethylating agents, respectively. Complete remission or complete remission with incomplete hematologic recovery was 56.1% and 19.7% with chemotherapy and hypomethylating agents, respectively (P

    (2022-03-22) Chianese, Giuseppina; Sirignano, Carmina; Benetti, Emanuele; Marzaroli, Vittoria; Collado, Juan A; de la Vega, Lauren; Appendino, Giovanni; Muñoz, Eduardo; Taglialatela-Scafati, Orazio
    A phytochemical analysis of mother liquors obtained from crystallization of CBD from hemp (Cannabis sativa), guided by LC-MS/MS and molecular networking profiling and completed by isolation and NMR-based characterization of constituents, resulted in the identification of 13 phytocannabinoids. Among them, anhydrocannabimovone (5), isolated for the first time as a natural product, and three new hydroxylated CBD analogues (1,2-dihydroxycannabidiol, 6, 3,4-dehydro-1,2-dihydroxycannabidiol, 7, and hexocannabitriol, 8) were obtained. Hexocannabitriol (8) potently modulated, in a ROS-independent way, the Nrf2 pathway, outperforming all other cannabinoids obtained in this study and qualifying as a potential new chemopreventive chemotype against cancer and other degenerative diseases.

    Intermolecular Interactions in G Protein-Coupled Receptor Allosteric Sites at the Membrane Interface from Molecular Dynamics Simulations and Quantum Chemical Calculations.
    (2022-09-30) Ding, Tianyi; Karlov, Dmitry S; Pino-Angeles, Almudena; Tikhonova, Irina G
    Allosteric modulators are called promising candidates in G protein-coupled receptor (GPCR) drug development by displaying subtype selectivity and more specific receptor modulation. Among the allosteric sites known to date, cavities at the receptor-lipid interface represent an uncharacteristic binding location that raises many questions about the ligand interactions and stability, the binding site structure, and how all of these are affected by lipid molecules. In this work, we analyze interactions in the allosteric sites of the PAR2, C5aR1, and GCGR receptors in three lipid compositions using molecular dynamics simulations. In addition, we performed quantum chemical calculations involving the symmetry-adapted perturbation theory (SAPT) and the natural population analysis to quantify the strength of intermolecular interactions. We show that besides classical hydrogen bonds, weak polar interactions such as O-HC, O-Br, and long-range electrostatics with the backbone amides contribute to the stability of allosteric modulators at the receptor-lipid interface. The allosteric cavities are detectable in various membrane compositions. The availability of polar atoms for interactions in such cavities can be assessed by water molecules from simulations. Although ligand-lipid interactions are weak, lipid tails play a role in ligand binding pose stability and the size of allosteric cavities. We discuss physicochemical aspects of ligand binding at the receptor-lipid interface and suggest a compound library enriched by weak donor groups for ligand search in such sites.

    Pathological changes and viral antigen distribution in tissues of Iberian hare (Lepus granatensis) naturally infected with the emerging recombinant myxoma virus (ha-MYXV).
    (2022-09-21) Agulló-Ros, Irene; Jiménez-Martín, Débora; Camacho-Sillero, Leonor; Gortázar, Christian; Capucci, Lorenzo; Cano-Terriza, David; Zorrilla, Irene; Gómez-Guillamón, Félix; García-Bocanegra, Ignacio; Risalde, María A
    A cross-species jump was confirmed in 2018, when a novel recombinant myxoma virus (MYXV) (ha-MYXV) caused high mortality in Iberian hare (Lepus granatensis) in the Iberian Peninsula. The aim of this study was to evaluate the main lesions, tissular distribution and target cells of ha-MYXV in Iberian hare. Gross postmortem examinations and histological and immunohistochemical studies to detect ha-MYXV were carried out in 28 animals that were confirmed as ha-MYXV positive by PCR. The main macroscopic lesions were bilateral blepharoconjunctivitis, epistaxis, intense congestion and oedema in several organs and some internal haemorrhages. Visible myxomas were not found. Histopathological examination revealed hyperplastic epidermis with predominant hyperkeratosis and myxoid matrix in the dermis. ha-MYXV-positive keratinocytes showed hydropic degeneration and cytoplasmic inclusion bodies. Alveolar oedema, interstitial pneumonia, dramatic lymphoid depletion in the spleen and necrosis in the liver and testis were observed. ha-MYXV was mainly detected in epithelial and myxoma cells in the skin, and also in macrophages, lymphocytes, fibroblasts and endothelial cells in several organs, as well as in hepatocytes and Leydig cells. A non-homogeneous number of samples were included in all the animals. Future experimental studies with controlled variables are necessary. These findings correspond to an unusual form of myxomatosis, characterised by an acute or hyperacute presentation.

    To examine the cross-sectional and longitudinal (2-year follow-up) associations between dietary diversity (DD) and depressive symptoms. An energy-adjusted dietary diversity score (DDS) was assessed using a validated FFQ and was categorised into quartiles (Q). The variety in each food group was classified into four categories of diversity (C). Depressive symptoms were assessed with Beck Depression Inventory-II (Beck II) questionnaire and depression cases defined as physician-diagnosed or Beck II >= 18. Linear and logistic regression models were used. Spanish older adults with metabolic syndrome (MetS). A total of 6625 adults aged 55-75 years from the PREDIMED-Plus study with overweight or obesity and MetS. Total DDS was inversely and statistically significantly associated with depression in the cross-sectional analysis conducted; OR Q4 v. Q1 = 0·76 (95 % CI (0·64, 0·90)). This was driven by high diversity compared to low diversity (C3 v. C1) of vegetables (OR = 0·75, 95 % CI (0·57, 0·93)), cereals (OR = 0·72 (95 % CI (0·56, 0·94)) and proteins (OR = 0·27, 95 % CI (0·11, 0·62)). In the longitudinal analysis, there was no significant association between the baseline DDS and changes in depressive symptoms after 2 years of follow-up, except for DD in vegetables C4 v. C1 = (β = 0·70, 95 % CI (0·05, 1·35)). According to our results, DD is inversely associated with depressive symptoms, but eating more diverse does not seem to reduce the risk of future depression. Additional longitudinal studies (with longer follow-up) are needed to confirm these findings.

    Olaparib maintenance monotherapy in platinum-sensitive relapsed ovarian cancer patients without a germline BRCA1/BRCA2 mutation: OPINION primary analysis.
    (2022-01-19) Poveda, A; Lheureux, S; Colombo, N; Cibula, D; Lindemann, K; Weberpals, J; Bjurberg, M; Oaknin, A; Sikorska, M; González-Martín, A; Madry, R; Pérez, M J Rubio; Ledermann, J; Davidson, R; Blakeley, C; Bennett, J; Barnicle, A; Škof, E
    The phase IIIb OPINION trial (NCT03402841) investigated olaparib maintenance monotherapy in patients without a deleterious or suspected deleterious germline BRCA1/BRCA2 mutation (gBRCAm) who had platinum-sensitive relapsed ovarian cancer (PSROC) and had received ≥2 previous lines of platinum-based chemotherapy. In this single-arm, open-label, international study, patients who had responded to platinum-based chemotherapy received maintenance olaparib tablets (300 mg twice daily) until disease progression or unacceptable toxicity. The primary endpoint was investigator-assessed progression-free survival (PFS) (modified RECIST version 1.1). A key secondary endpoint was PFS by homologous recombination deficiency (HRD) and somatic BRCAm (sBRCAm) status. The primary analysis of PFS was planned for 18 months after the last patient received their first dose. Two hundred and seventy-nine patients were enrolled and received olaparib. At data cutoff (October 2, 2020), 210 PFS events had occurred (75.3% maturity) and median PFS was 9.2 months (95% confidence interval [CI], 7.6-10.9) in the overall population. At 12 and 18 months, 38.5% and 24.3% of patients were progression-free, respectively. In the predefined biomarker subgroups, median PFS was 16.4, 11.1, 9.7, and 7.3 months in sBRCAm, HRD-positive including sBRCAm, HRD-positive excluding sBRCAm, and HRD-negative patients, respectively. The most common treatment-emergent adverse events (TEAEs) were nausea (48.4%) and fatigue/asthenia (44.1%). TEAEs led to dose interruption, dose reduction, and treatment discontinuation in 47.0%, 22.6%, and 7.5% of patients, respectively. Maintenance olaparib demonstrated clinical benefit in patients without a gBRCAm, and across all subgroups, compared with historical placebo controls. There were no new safety signals.

    Kisspeptins and the neuroendocrine control of reproduction: Recent progress and new frontiers in kisspeptin research.
    (2022-01-07) Sobrino, Veronica; Avendaño, Maria Soledad; Perdices-López, Cecilia; Jimenez-Puyer, Manuel; Tena-Sempere, Manuel
    In late 2003, a major breakthrough in our understanding of the mechanisms that govern reproduction occurred with the identification of the reproductive roles of kisspeptins, encoded by the Kiss1 gene, and their receptor, Gpr54 (aka, Kiss1R). The discovery of this unsuspected reproductive facet attracted an extraordinary interest and boosted an intense research activity, in human and model species, that, in a relatively short period, established a series of basic concepts on the physiological roles of kisspeptins. Such fundamental knowledge, gathered in these early years of kisspeptin research, set the scene for the more recent in-depth dissection of the intimacies of the neuronal networks involving Kiss1 neurons, their precise mechanisms of regulation and the molecular underpinnings of the function of kisspeptins as pivotal regulators of all key aspects of reproductive function, from puberty onset to pulsatile gonadotropin secretion and the metabolic control of fertility. While no clear temporal boundaries between these two periods can be defined, in this review we will summarize the most prominent advances in kisspeptin research occurred in the last ten years, as a means to provide an up-dated view of the state of the art and potential paths of future progress in this dynamic, and ever growing domain of Neuroendocrinology.

    The ratio of caesarean has been increasing considerably in many countries. Planning a vaginal birth after a previous caesarean is considered an important option for women in a subsequent pregnancy. To analyse obstetric and neonatal outcomes in women in labour after caesarean section before and during the COVID-19 pandemic, and to determine factors associated with successful vaginal birth after caesarean (VBAC). Observational cohort study of women in labour with history of caesarean section who gave birth between March 2019 and December 2020 in a tertiary hospital in southern Spain. Consecutive sampling was performed using the maternal birth database and a descriptive and inferential analysis of the study variables was carried out. Socio-demographic, obstetric and neonatal variables were compared between the pre-pandemic and pandemic periods. Multiple logistic regression analysis was performed to determine variables associated with VBAC success. The VBAC success rate was 67.4%. The caesarean section rate was significantly higher during the COVID-19 pandemic period. Factors associated with VBAC success were: birth before the pandemic (OR 0.32) and at night (OR 0.45), use of epidural analgesia (OR 2.14), and having had a previous vaginal birth (OR 1.98). The success rate of VBAC was lower during the pandemic. Knowledge of the factors related to VBAC success is critical for practitioners when supporting women in decision-making about mode of birth after a previous caesarean section.

    Understanding the adipose tissue acetylome in obesity and insulin resistance.
    (2022-03-05) Navarro-Ruiz, Maria Del Carmen; López-Alcalá, Jaime; Díaz-Ruiz, Alberto; Moral, Sandra Díaz Del; Tercero-Alcázar, Carmen; Nieto-Calonge, Andrea; López-Miranda, José; Tinahones, Francisco J; Malagón, María M; Guzmán-Ruiz, Rocío
    Obesity is a widely prevalent pathology with a high exponential growth worldwide. Altered lipid accumulation by adipose tissue is one of the main causes of obesity and exploring lipid homeostasis in this tissue may represent a source for the identification of possible therapeutic targets. The study of the proteome and the post-translational modifications of proteins, specifically acetylation due to its involvement in energy metabolism, may be of great interest to understand the molecular mechanisms involved in adipose tissue dysfunction in obesity. The objective of this study was to characterize the subcutaneous and omental adipose tissue acetylome in conditions of obesity and insulin resistance and to describe the importance of acetylation of key molecules in adipose tissue to use them as therapeutic targets. The results describe for the first time the acetylome of subcutaneous and omental adipose tissue under physiological and physiopathological conditions such as obesity and insulin resistance. New evidence showed different acetylation patterns between two main depots and highlight the molecular complexity of adipose tissue. Results showed changes in FABP4 acetylation in subcutaneous fat in relation to insulin resistance, thus unveiling a potential marker of depot-specific dysfunctional expansion in obesity-associated metabolic disease. Furthermore, it is shown that the acetylation of FABP4 affects its function, modulating the capacity of differentiation in adipocytes. In conclusion, this study demonstrates a profound, depot-specific alteration of adipose tissue acetylome, wherein the acetylation of FABP4 may play a key role in adipocyte differentiation and lipid accumulation.

    Hospital Management and Ambulatory Patient Care After COVID-19 Infection in Kidney Transplant.
    (2021-11-12) Redondo, Magdalena Terán; Martínez, Claudia Muñoz; Guerrero, Pedro Rosa; Morales, M Luisa Agüera; De Rueda, Álvaro Torres; Benot, Alberto Rodríguez
    A large number of registries have been collected for kidney transplant recipients infected with COVID-19. From March 2020 to April 2021, our team conducted an observational study, which included all patients who showed a polymerase chain reaction positive for COVID-19. Patients were divided into 2 groups: patients who required ambulatory care and patients who needed hospital admission. A total of 76 kidney transplant recipients were infected with COVID-19. A total of 33% required hospital admission and 65% received ambulatory treatment; 28% of our patients were asymptomatic and 6.8% died. Immunosuppressive treatment was modified in both study groups, and there were not any acute rejection episodes or changes in the human leukocyte antigen antibodies profile in our patients during our clinical trial. In our study there was a significant percentage of patients who did not require hospital admission compared with other studies. In addition, we think that the reduction of immunosuppression can be a safe and reliable treatment.

    [Quantitative analysis of COVID-19 and its psychological and educational impacts on university and secondary students in Córdoba, Spain].
    (2022-03-14) Castro Jiménez, R A; Jaén Moreno, M J; Y López Del Río, L C; Fruet-Cardozoes, J V
    The COVID-19 pandemic that began in Wuhan, China, at the end of 2019, and which today threatens all the inhabitants of the planet, is currently the priority research topic. In this context, this article focuses on how this health problem directly affects the psychological and educational status of 344 university and high school students in Córdoba, Spain. For the analysis, the structural equation model (SEM) has been used, through the quantification of a set of relationships between one or more independent variables, trying to condense the pandemic scenario and its health, psychological and educational implications. The first latent variable "Health" is causal of the latent variable "Psychology", and, of the endogenous variables, "social relations effects", "sadness effects" and "sexuality effects", which confirms that the COVID-19 seriously affected the psychological behavior of university and high school students in Córdoba.

    Factors associated with atherosclerosis in radiographic and non-radiographic axial spondyloarthritis. A multicenter study on 838 patients.
    (2022-05-28) Rueda-Gotor, Javier; Ferraz-Amaro, Iván; Genre, Fernanda; González-Mazón, Iñigo; Corrales, Alfonso; Calvo-Rio, Vanesa; Portilla, Virginia; Llorca, Javier; Expósito, Rosa; Hernández-Hernández, Vanesa; Quevedo-Abeledo, Juan Carlos; Rodríguez-Lozano, Carlos; Lopez-Medina, Clementina; Ladehesa-Pineda, María Lourdes; Castañeda, Santos; Vicente, Esther F; Fernández-Carballido, Cristina; Martínez-Vidal, M Paz; Castro-Corredor, David; Anino-Fernández, Joaquín; Peiteado, Diana; Plasencia-Rodríguez, Chamaida; García-Vivar, María Luz; Galíndez-Agirregoikoa, Eva; Montes-Perez, Esther; Fernández-Díaz, Carlos; Blanco, Ricardo; González-Gay, Miguel Ángel
    To identify disease-related factors associated with subclinical atherosclerosis and cardiovascular (CV) events in a large series of patients with axial spondyloarthritis (axSpA) and to identify possible differences in the effect of the potential pro-atherogenic factors between ankylosing spondylitis (AS) non-radiographic axSpA (nr-axSpA). This is a cross-sectional observational study of the AtheSpAin cohort, a Spanish multicenter cohort to study atherosclerosis in axSpA. Subclinical atherosclerosis determined by carotid ultrasound included assessment of carotid intima-media thickness (cIMT) and plaque detection. 639 AS and 167 nr-axSpA patients were recruited. CV risk factors (CRF) and several disease-related factors showed a statistically significant association with subclinical atherosclerosis in the crude analysis. After adjustment for age, sex, and smoking (model 1), associations remained statistically significant for spinal mobility, inflammatory bowel disease, use of prednisone, and Disease-modifying antirheumatic drugs (DMARD) when assessing carotid plaques and for acute phase reactants (APR) at diagnosis, use of prednisone, DMARD, and TNF-inhibitors when measuring cIMT. In model 2, which also included classic CRF as confounding factors to identify axSpA features with a potential independent pro-atherogenic effect, the functional status was the only variable significantly associated with plaques and the use of prednisone and APR at diagnosis with cIMT. No association differences were found between both subtypes of patients. Besides, APR at diagnosis were also associated with subsequent development of CV events that had occurred in 33 patients. Apart from CRF, atherosclerotic disease in AxSpA is associated with disease-related factors such as inflammatory response and disease severity, with no differences between AS and nr-axSpA.

    Of the numerous animal species affected by the SARS-CoV-2 virus, cats are one of the most susceptible, and cat-to-cat transmission has been described. Although cat-to-human infection has not, as yet, been demonstrated, preventive measures should be taken in order to avoid both viral infection in cats and transmission among them. In this respect, the application of an effective vaccine to at-risk populations would be a useful tool for controlling the disease in this species. Here, we test a new vaccine prototype based on the Spike protein of the virus in order to prevent infection and infectious virus shedding in cats. The vaccine employed in experimentation, and which is easily produced, triggered a strong neutralizing antibody response in vaccinated animals. In contrast to that which occurred with control animals, no infectious virus was detected in the oropharyngeal or rectal swabs of vaccinated cats submitted to a SARS-CoV-2 challenge. These results are of great interest as regards future considerations related to implementing vaccination programs in pets. The value of cats as vaccination trial models is also described herein.

    Development and feasibility of 4 checklists for the evaluation of comorbidity in patients with rheumatoid arthritis, axial spondyloarthritis and psoriatic arthritis: GECOAI Project.
    (2021-04-07) Castañeda, Santos; González, Carlos; Villaverde, Virginia; Lajas Petisco, Cristina; Castro, María Carmen; Jirout, Fernando; Obaya, Juan Carlos; Hermosa, Juan Carlos; Suárez, Carmen; García, Silvia; Rodero, María; León, Leticia; López Esteban, Amparo; Gobbo, Milena; Alcaide, Laly; Torre-Alonso, Juan Carlos
    To develop and assess the feasibility in daily practice of four comorbidity checklists, for common use in rheumatoid arthritis (RA), axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA). A multidisciplinary panel of experts on comorbidity was established. Data from the GECOAR, GECOAX and GECOAP projects were analysed and a narrative literature review in Medline on RA, axSpA and PsA comorbidity was performed in order to select the most relevant and common comorbidities across the three diseases. With these results and those obtained from a focus group of patients, in a nominal group meeting, the experts generated preliminary checklists. These were afterwards modified by an external evaluation by two associations, a patients' association and an association of health professionals related to rheumatology. As a result, the final checklists were generated. A cross-sectional study was conducted to test the feasibility of three of the checklists in daily practice, in which eight health professionals evaluated the checklists in five patients with RA, five with axSpA and five with SpA. Four comorbidity checklists were designed, three for health professionals (one to assess current comorbidity, one on prevention/health promotion and one with the referral criteria to other health professionals), and another for patients. The feasibility study showed them to be simple, clear, and useful for use in routine clinical practice. The use of specific and common checklists for patients with RA, axSpA and PsA is feasible and might contribute favorably to their prognosis as well as in daily practice.

    Experts document on methotrexate use in combined therapy with biological or targeted synthetic disease modifying drugs in patients with rheumatoid arthritis.
    (2022) Tornero-Molina, Jesús; Alperi-López, Mercedes; Castellví, Ivan; de Agustín-de Oro, Juan José; Escudero, Alejandro; García-Vicuña, Rosario; González-Gay, Miguel Ángel; Hidalgo, Cristina; Rubio, Esteban; Sanmartí, Raimon; Casamira, Núria; Calvo-Alén, Jaime
    We aimed to develop recommendations for the management of methotrexate (MTX) when considering the combination with biological (b) or targeted synthetic (ts) disease modifying drugs (DMARDs) in rheumatoid arthritis (RA). Eleven experts on RA were selected. Two coordinators formulated 13 questions about the combination therapy of MTX with bDMARDs or tsDMARDs. A systematic review was conducted to answer the questions. Inclusion and exclusion criteria were established as well as the search strategies (Medline, Embase and the Cochrane Library were searched up to January 2019). Two reviewers selected the articles and collected data. Simultaneously, EULAR and ACR meeting abstracts were evaluated. Based on this evidence, the coordinators proposed preliminary recommendations that the experts discussed and voted in a nominal group meeting. The level of evidence and grade of recommendation was established using the Oxford Center for Evidence Based Medicine and the level of agreement with a Delphi. Agreement was established if at least 80% of the experts voted 'yes' (yes/no). The systematic review retrieved 513 citations of which 61 were finally included. A total of 10 recommendations were generated, voted and accepted. The level of agreement was very high in all of them and it was achieved in the first Delphi round. Final recommendations cover aspects such as the optimal MTX dosage, tapering strategy or patients' risk management. This document is intended to help clinicians solve usual clinical questions and facilitate decision making when treating RA patients with MTX in combination with bDMARDs or tsDMARDs.
