Effects of a mindfulness-based program on the occupational balance and mental health of university students. Protocol for a randomized controlled trial.

OBJECTIVE: The aim is to examine whether the addition of Virtual Reality (VR) meditation training to a standard 8-week Mindfulness-Based Health Care Program (MBHC-VR) results in a significantly increased improvement in occupational, mental health, and psychological functioning versus MBHC-only in university students. MATERIALS AND METHODS: A randomized controlled clinical trial with three arms (MBHC, MBHC-VR, Control Group), four assessment time points (pre-intervention, inter-session, post-intervention, and 3-month follow-up), and mixed methodology will be proposed. University students (undergraduate, master, or doctoral) interested in participating and who meet the inclusion/exclusion criteria will be included over two years. Data will be collected from different ad hoc questionnaires, several standardized tests, and an Ecological Momentary Assessment. We will use R software to carry out descriptive analyses (univariate and bivariate), multilevel modeling, and structural equation models to respond to the proposed objective. The qualitative analysis will be carried out using the MAXQDA program and the technique of focus groups. DISCUSSION: It is expected that with the proposed intervention university students will learn to relate in a healthier way with their mental processes, so as to improve their occupational balance (OB) and their psychological well-being. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT05929430.

Platelet C3G: a key player in vesicle exocytosis, spreading and clot retraction.

C3G is a Rap1 GEF that plays a pivotal role in platelet-mediated processes such as angiogenesis, tumor growth, and metastasis by modulating the platelet secretome. Here, we explore the mechanisms through which C3G governs platelet secretion. For this, we utilized animal models featuring either overexpression or deletion of C3G in platelets, as well as PC12 cell clones expressing C3G mutants. We found that C3G specifically regulates α-granule secretion via PKCδ, but it does not affect δ-granules or lysosomes. C3G activated RalA through a GEF-dependent mechanism, facilitating vesicle docking, while interfering with the formation of the trans-SNARE complex, thereby restricting vesicle fusion. Furthermore, C3G promotes the formation of lamellipodia during platelet spreading on specific substrates by enhancing actin polymerization via Src and Rac1-Arp2/3 pathways, but not Rap1. Consequently, C3G deletion in platelets favored kiss-and-run exocytosis. C3G also controlled granule secretion in PC12 cells, including pore formation. Additionally, C3G-deficient platelets exhibited reduced phosphatidylserine exposure, resulting in decreased thrombin generation, which along with defective actin polymerization and spreading, led to impaired clot retraction. In summary, platelet C3G plays a dual role by facilitating platelet spreading and clot retraction through the promotion of outside-in signaling while concurrently downregulating α-granule secretion by restricting granule fusion.

Unveiling the inherent physical-chemical dynamics: Direct measurements of hydrothermal fluid flow, heat, and nutrient outflow at the Tagoro submarine volcano (Canary Islands, Spain).

Tagoro is one of the few submarine volcanoes in the world that has been monitored since its early eruptive stage in 2011 to present day. After six multidisciplinary oceanographic cruises conducted between 2014 and 2023 to gather a comprehensive dataset of georeferenced video-imagery and in situ measurements of hydrothermal flow velocities and hydrothermal fluid samples, we provide a robust characterization of the ongoing hydrothermal fluid velocity, heat flux, and nutrient release, along with an accurate delimitation of the hydrothermal field area. Our results reveal that Tagoro hydrothermal system extends from the main hydrothermal crater up to the summit, covering an area of 7600 m2. This hydrothermal field comprises thousands of small individual vents, displaying diverse morphologies such as crevices and delicate chimney-like structures, irregularly scattered across the dominant diffuse venting surface. Hydrothermal fluid temperatures and velocities at the substratum level reveal a clustered spatial distribution, ranging from 21.0 to 33.3 °C and 1.6-26.8 cm min-1, respectively. Furthermore, our findings indicate a discernible correlation between hydrothermal fluid temperature and vent density, while significant differences were observed between velocities from diffuse and focused areas. Additionally, heat fluxes exceed 200 MW across the entire active region, with heat flux values ranging from 6.06 to 146.87 kW m-2 and dissolve inorganic nutrient concentrations exhibit significant enrichments, comparable to the magnitude of important nutrient sources in the area as upwelling systems or mesoscale structures.

Morphological Hallmarks of Classical Fabry Disease: An Ultrastructural Study in a Large Spanish Family.

Fabry disease (FD) is a rare lysosomal disorder caused by α-galactosidase A deficiency, and it leads to the systemic deposition of globotriasylceramide. Demonstrations of the storage material in biopsies support this diagnosis. We report a histological and ultrastructural study of biopsies that were performed on 11 individuals from a family with the variant p.Gln279Arg in GLA, which is associated with the classical phenotype of Fabry disease. Intralysosomal deposits were found in all biopsies, corresponding to the skin, kidney, and endomyocardium in both sexes and at different ages. In nine of the skin biopsies, deposits were analysed by immunofluorescence and quantified at the ultrastructural level. Then, the findings were compared according to sex, genotype, and treatment. The quantification of the deposits in the skin biopsies revealed a broader involvement in men than in women. A significant clearance of the deposits was observed in one case after treatment. Tissue involvement was remarkable at diagnosis in all individuals. The findings from the skin biopsies were demonstrative of classic FD, thus supporting the diagnosis; repeated biopsy analyses suggested the benefit of early treatment.

Older persons' expressed perceptions on exercise programs in long-term care institutions: Influence of professionals and institutions.

OBJECTIVE: To explore the perceptions of institutionalised older people about the professionals and institutions regarding exercise programs in long-term care institutions DESIGN, SETTING, AND PARTICIPANTS: A qualitative study was carried out using focus group discussions. Forty-seven institutionalised participants (≥ 65 years old) with a score of > 23 in the Mini-Mental State Examination (MMSE) were recruited. RESULTS: Most participants believed that the frequency of the exercise sessions could be increased by enhancing the number of staff assisting them and by adapting the facilities to their needs. They also suggested using outdoor spaces and avoiding childish activities and treatment. Participants' beliefs were grouped into three major themes (i) Perceptions about the health professionals delivering the exercise programs (ii) Perceptions about the institution or centre regarding exercise programs; (iii) Perceptions about the exercise programs. CONCLUSION: Participants proposed certain changes that could take place in the institutions to promote engagement with exercise programs: tailored exercise programs, avoiding puerile treatment, increasing the number of staff members, and the creation of well-equipped spaces to perform the exercise. PRACTICAL IMPLICATIONS: Professionals should spend time designing tailored exercise programs and avoid puerile treatment. Institutions must review the need for spaces and the personnel assigned.

Decalogue to promote the implementation and improvement of recommendations for the early diagnosis of HIV in Emergency Departments.

Early diagnosis of HIV is still a challenge. Emergency Departments (EDs) suppose ideal settings for the early detection of HIV, since patients with high prevalence of hidden HIV infection are frequently attending those services. In 2020, the Spanish Society of Emergency and Emergency Medicine (SEMES) published a series of recommendations for the early diagnosis of patients with suspected HIV infection and their referral and follow-up in the EDs as part of its "Deja tu huella" program. However, the application of these recommendations has been very heterogeneous in our country. Considering this, the working group of the HIV hospital network led by the SEMES has motivated the drafting of a decalogue, with the aim of promoting the implementation and improvement of protocols for the early diagnosis of HIV in Spanish EDs.

Real-world effectiveness and factors associated with increased mortality in non-critically ill patients with COVID-19 pneumonia receiving remdesivir.

OBJECTIVES: Evidence on the effectiveness of remdesivir when used in real-life clinical practice is controversial. This study aims to analyse its effectiveness and the factors associated with increased mortality in non-critically ill patients with COVID-19 pneumonia who require supplemental low-flow oxygen and received remdesivir. METHODS: A retrospective cohort study was conducted at Ramón y Cajal University Hospital (Madrid, Spain) which included all patients treated with remdesivir in our institution during the second pandemic breakout in Spain, from August to November 2020. Treatment with remdesivir was limited to non-critically ill patients with COVID-19 pneumonia requiring low-flow supplemental oxygen, with a treatment duration of 5 days. RESULTS: A total of 1757 patients were admitted with COVID-19 pneumonia during the study period, of which 281 non-critically ill patients were treated with remdesivir and included in the analysis. Mortality at 28 days after initiation of treatment was 17.1%. The median (IQR) time to recovery was 9 days (6-15). 104 (37.0%) patients had complications during hospitalisation, with renal failure being the most frequent (31 patients; 36.5%). After adjustment for confounding factors, high-flow oxygen therapy was associated with increased 28-day mortality (HR 2.77; 95% CI 1.39 to 5.53; p=0.004) and decreased 28-day clinical improvement (HR 0.54; 95% CI 0.35 to 0.85; p=0.008). A significant difference in survival and clinical improvement was identified between patients treated with high and low-flow oxygen. CONCLUSION: The 28-day mortality rate in patients treated with remdesivir needing low-flow oxygen therapy was higher than that published in clinical trials. Age and increased oxygen therapy needed after the beginning of treatment were the main risk factors associated with mortality.

Dynamic antagonism between key repressive pathways maintains the placental epigenome.

DNA and Histone 3 Lysine 27 methylation typically function as repressive modifications and operate within distinct genomic compartments. In mammals, the majority of the genome is kept in a DNA methylated state, whereas the Polycomb repressive complexes regulate the unmethylated CpG-rich promoters of developmental genes. In contrast to this general framework, the extra-embryonic lineages display non-canonical, globally intermediate DNA methylation levels, including disruption of local Polycomb domains. Here, to better understand this unusual landscape's molecular properties, we genetically and chemically perturbed major epigenetic pathways in mouse trophoblast stem cells. We find that the extra-embryonic epigenome reflects ongoing and dynamic de novo methyltransferase recruitment, which is continuously antagonized by Polycomb to maintain intermediate, locally disordered methylation. Despite its disorganized molecular appearance, our data point to a highly controlled equilibrium between counteracting repressors within extra-embryonic cells, one that can seemingly persist indefinitely without bistable features typically seen for embryonic forms of epigenetic regulation.

Meningococcal carriage in men who have sex with men presenting at a sexual health unit in Spain.

Neisseria meningitidis (Nm) is asymptomatically carried in the nasopharynx of 5-10% adults, although certain populations, such as men who have sex with men (MSM), exhibit a higher colonisation rate. Interest in Nm carriage has been renewed, owed to meningitis outbreaks within populations of MSM. The aim of this study was to characterise Nm isolates and risk factors for its carriage among MSM attending a sexual health unit. A retrospective cross-sectional study was undertaken between June 2018 and December 2021. We took anal, oropharyngeal, urethral, and blood samples as part of the sexually transmitted infection screening procedures routinely implemented. Nm isolates were subjected to antimicrobial susceptibility testing; the serogroup and genogroup were determined by multi-locus sequence typing. A total of 399 subjects were recruited, and the Nm oropharyngeal carriage rate was 29%, similar among both people living with HIV (PLWH) and uninfected individuals. Nm carriage was less common in vaccinated individuals, especially those who had received the tetravalent vaccine (2.6% vs. 10.6%, p = 0.008). The most frequent serogroups were B (40%) and non-groupable (45%). Most of the isolates were susceptible to ciprofloxacin (96%) and ceftriaxone (100%). However, we identified 21 strains (20%) belonging to hyperinvasive lineages (CC11, CC4821, CC32, CC41/44, CC213, and CC269), most of which belonged to serogroup B. Given that vaccination with MenACWY was associated with a low Nm carriage, we encourage routine vaccination of all MSM. Moreover, the administration of the meningitis B vaccine should also be assessed considering that several invasive lines included in serogroup B are circulating among MSM.

Addition of tDCS and TENS to an education and exercise program in subjects with knee osteoarthritis: A study protocol.

BACKGROUND: Knee osteoarthritis often leads to chronic pain that frequently becomes disabling.Osteoarthritis has been linked to maladaptive plasticity in the brain, which can contribute to chronic pain. Therapies including neuromodulation and peripheral electrical stimulation are used to counteract the maladaptive plasticity of the brain. OBJECTIVE: To determine the efficacy of the addition of tDCS and TENS to an education and exercise program in reducing pain. METHODS: Over a 2-week study period, 60 participants will complete an exercise and educational intervention. Eligible participants accepting to participate will be subsequently randomized into one of the three treatment groups: 1) Active Transcranial Direct Current Stimulation (tDCS) and active Transcutaneous Electrical Nerve Stimulation (TENS); 2) Active tDCS and sham TENS; 3) Sham tDCS and sham TENS. RESULTS: The primary outcome will be subjective pain intensity. SECONDARY OUTCOMES: quality of life, physical function, central sensitization, and pain adjuvants (uncertainty, catastrophizing kinesiophobia, adverse events). CONCLUSION: This clinical trial will provide data on the effect that the addition of tDCS and/or TENS to an education and exercise program may have to counteract maladaptive plastic changes and improve the benefits of exercises, and whether the combination of both neuromodulator techniques may have a higher magnitude of effect.

Parents of children with disabilities' perceptions regarding the quality of interaction with Health professionals working in early intervention: A qualitative descriptive study.

AIMS AND OBJECTIVES: The aim of this study is to explore the perceptions of parents of children with physical disabilities concerning the quality of their interaction with health professionals in early intervention programs. BACKGROUND: Despite the consensus on the need for Patient and Family-Centered Care, there are still difficulties when executing such care. The quality of interaction among patients, families, and professionals is essential to facilitate the implementation of the programs. DESIGN: A qualitative descriptive study with thematic analysis using a Modified Grounded Theory approach. METHODS: Data were collected through seven focus groups with 28 parents of children with physical disabilities who were undergoing early intervention programs in three centres. The study followed the COREQ guidelines and checklist. RESULTS: Two themes emerged from the experiences: 'exchange of information and education', which included all the activities, procedures, exercises and skills taught by the professionals to help parents care for their child; and 'interpersonal skills', which focused on the way the professional relates with the child and the parents. Several subthemes emerged within each theme. CONCLUSIONS: This study identified which elements of the professional-parent interaction are considered by parents when evaluating the quality of their interaction with the health care provider of their children. RELEVANCE TO CLINICAL PRACTICE: The results of this study bring to light certain behaviours and interactions that health professionals should consider in order to improve the perceptions of parents of children with disabilities regarding the quality of interaction in the context of early childhood intervention. PATIENT OR PUBLIC CONTRIBUTION: Parents contributed to the data collected. Early intervention professionals were involved in participant checking to ensure the rigour of the study.

Life stories: Unraveling the academic configuration of a multifaceted and multidisciplinary field of knowledge.

In the field of qualitative research, life stories are consolidated as one of the most important techniques within the biographical method. However, due to the multiplicity of techniques covered by this method and the disciplines in which it is applied, the contributions and scope of life histories do not present a clear delimitation. By contrast, a considerable conceptual confusion persists and the transfer of its production remains very narrow. In this sense, this article aims to clarify the field of knowledge generated through life stories. To this end, it innovatively applies the bibliometric method. Making use of performance analysis and scientific mapping through the VosViewer application, it studies a body of 2670 articles indexed in the Web of Science. The results show how knowledge transferred from psychology through its major schools of thought occupies a central place. This leaves in a secondary position the knowledge produced by other disciplines such as sociology or anthropology, which is not transferred in the main forums of scientific impact. In this way, the conclusion points to the need to open up new lines of research to find out the differences between the different techniques and disciplines when applying this methodology.

Shall we start? Ready, set, go! Toward early intervention in infants with unilateral cerebral palsy. A randomized clinical trial protocol.

Background: It is crucial to start an early intervention in unilateral cerebral palsy. Intensive therapies are focused on training based on activities. Objective: The objective of the study was to study the changes in the bimanual functional performance (BFP) after early intensive therapies at home compared with standard care in children with unilateral cerebral palsy from 9 to 18 months of age. Design: A single-blind comparative effectiveness study will be conducted. Methods and Analysis: Children will be randomized into four groups: infant-mCIMT, infant-BIT, infant-hybrid, and infant standard therapy (control group, CG). Each early intensive protocol will last 50 h and will be applied throughout a 10-week period with the family involvement at home. The main outcomes are BFP measure with mini-Assisting Hand Assessment (mini-AHA) scale, functional goals measure with Goal Attainment Scale (GAS), and satisfaction and expectations on intensive therapy from parents measure through specific questionnaire. Baseline characteristics between groups will be compared using independent t test and Fisher's exact test. Pre- and post-treatment outcomes of standard assessments will be compared using analysis of variance (ANOVA) for parametric and Kruskal-Wallis test for non-parametric variables. The Bonferroni correction is applied for multiple comparisons. An alpha level of p ⩽ 0.05 is considered significant. Discussion: In relation to other studies that have analyzed intensive therapies, although with fewer intervention groups, it seems that the application of any of the intensive interventions is effective with the applied dose to obtain changes in BFP and increase the spontaneous use of the affected upper limb. Registration: ClinicalTrials.gov Identifier: NCT04642872.

Cognitive Intervention Programs in Minors Belonging to Disadvantaged Contexts in Spain: A Systematic Review.

Research studies show a strong influence of socioeconomic status (SES) on human development, and how the exposure to risk contexts in the earliest stages translates into dangers in the cognitive development of children and adolescents. To alleviate these consequences and favour development, different cognitive training programs have contributed to this field by identifying the criteria of efficacy. This systematic review identifies and synthesizes the evidence of cognitive intervention studies implemented with psychosocial risk groups carried out in Spain. The search strategy was adapted to different databases. Only studies published in English or Spanish and developed in Spain that included interventions applied in populations aged 5 to 18 years with a low SES were included. The analysis of the literature showed nine interventions that indicated an improvement in those cognitive functions worked with low SES children. The cognitive domains that most worked were executive functions, followed by social cognition and language. After reviewing the available literature, a clear scarcity of interventions carried out in Spain was observed. Variables such as age, cognitive functions or personal vulnerability were identified as factors to be taken into account in future lines of research due to their influence on minors. These findings indicate the relevance of this review to help decision-making in relation to the actions to be carried out by the competent bodies in Spain.

Knowledge and Attitudes towards Patient Safety among Students in Physical Therapy in Spain: A Longitudinal Study.

(1) Background: Patient safety is a discipline of health care management aiming to prevent and reduce errors and harm to patients. The assessment of knowledge and attitudes on patient safety among students in physical therapy is still scarce; no studies have yet explored the changes that internship periods may produce. Objectives: 1. to determine the attitudes and knowledge of students in physical therapy with respect to patient safety in a Spanish University; and 2. to explore changes following a practical internship period. (2) Methods: Longitudinal study. Data from the Attitudes to Patient Safety Questionnaire III (APSQ-III) before and after the internship period were obtained from an initial sample of 125 students and average positive response rates were compared. (3) Results: "Team functioning", "Importance of patient safety in the curriculum", and "Error inevitability" displayed the highest scores, in accordance with the current literature. After the internship period, the dimensions "Patient safety training received" (p = 0.001), "Error reporting confidence" (p = 0.044), and "Professional incompetence as an error cause" (p = 0.027) showed significant changes. (4) Conclusions: The current study, highlighting areas of strengths and weaknesses in the knowledge and attitudes of students in physical therapy towards patient safety, may be a foundation to adopt tailored programs to enhance students' competencies in patient safety.

Polycomb repressive complex 2 shields naïve human pluripotent cells from trophectoderm differentiation.

The first lineage choice in human embryo development separates trophectoderm from the inner cell mass. Naïve human embryonic stem cells are derived from the inner cell mass and offer possibilities to explore how lineage integrity is maintained. Here, we discover that polycomb repressive complex 2 (PRC2) maintains naïve pluripotency and restricts differentiation to trophectoderm and mesoderm lineages. Through quantitative epigenome profiling, we found that a broad gain of histone H3 lysine 27 trimethylation (H3K27me3) is a distinct feature of naïve pluripotency. We define shared and naïve-specific bivalent promoters featuring PRC2-mediated H3K27me3 concomitant with H3K4me3. Naïve bivalency maintains key trophectoderm and mesoderm transcription factors in a transcriptionally poised state. Inhibition of PRC2 forces naïve human embryonic stem cells into an 'activated' state, characterized by co-expression of pluripotency and lineage-specific transcription factors, followed by differentiation into either trophectoderm or mesoderm lineages. In summary, PRC2-mediated repression provides a highly adaptive mechanism to restrict lineage potential during early human development.

Description of the first Spanish case of Gerstmann-Sträussler-Scheinker disease with A117V variant: clinical, histopathological and biochemical characterization.

Gerstmann-Sträussler-Scheinker disease (GSS) is a rare neurodegenerative illness that belongs to the group of hereditary or familial Transmissible Spongiform Encephalopathies (TSE). Due to the presence of different pathogenic alterations in the prion protein (PrP) coding gene, it shows an enhanced proneness to misfolding into its pathogenic isoform, leading to prion formation and propagation. This aberrantly folded protein is able to induce its conformation to the native counterparts forming amyloid fibrils and plaques partially resistant to protease degradation and showing neurotoxic properties. PrP with A117V pathogenic variant is the second most common genetic alteration leading to GSS and despite common phenotypic and neuropathological traits can be defined for each specific variant, strikingly heterogeneous manifestations have been reported for inter-familial cases bearing the same pathogenic variant or even within the same family. Given the scarcity of cases and their clinical, neuropathological, and biochemical variability, it is important to characterize thoroughly each reported case to establish potential correlations between clinical, neuropathological and biochemical hallmarks that could help to define disease subtypes. With that purpose in mind, this manuscript aims to provide a detailed report of the first Spanish GSS case associated with A117V variant including clinical, genetic, neuropathological and biochemical data, which could help define in the future potential disease subtypes and thus, explain the high heterogeneity observed in patients suffering from these maladies.

Targeted screening for human immunodeficiency virus infection in Spanish emergency departments: an analysis of epidemiologic and economic impact. / Cribado dirigido del virus de la inmunodeficiencia humana en los servicios de urgencias en España: análisis de las consecuencias epidemiológicas y económicas.

OBJECTIVES: To evaluate the potential epidemiologic and economic impact of applying an HIV screening protocol in hospital emergency departments (ED) and compare it to current clinical practice in Spain. MATERIAL AND METHODS: We estimated the cumulative incidence of human immunodeficiency virus (HIV) infections and associated costs in Spain for a 20-year time horizon based on a model comprised of various health states with different risks for HIV transmission. The impact of current clinical practices in Spain, in which there is no established protocol for HIV screening, was compared to the potential impact of applying a targeted screening protocol in persons who come to the ED with certain conditions suggestive of HIV infection (diagnosis of a sexually transmitted infection, mononucleosis, herpes zoster infection, community-acquired pneumonia; practice of chemsex, and need for postexposure prophylaxis). RESULTS: Screening all persons with a condition suggestive of HIV infection in hospital EDs would require an investment of €20 million over 20 years, but it would prevent 13 615 new infections (reducing the incidence by 20.6%, down from 66 265 to 52 650 cases) in comparison with the current diagnostic approaches. Such a reduction in the incidence of HIV infection would potentially save €4411 million over 20 years, giving a return of €224 per euro invested. CONCLUSION: A protocol for targeted screening of persons in circumstances suggestive of risk for HIV infection in Spain would increase diagnoses, avert new infections, and generate savings in comparison with screening practices currently in effect.

OBJETIVO: El objetivo del análisis fue evaluar el impacto epidemiológico y económico de protocolizar el cribado dirigido del virus de la inmunodeficiencia humana (VIH) en los servicios de urgencias hospitalarios (SUH) comparado con la actual práctica clínica en España. METODO: Mediante un modelo formado por varios estados de salud con diferentes riesgos de transmisión se estimó la incidencia acumulada de infecciones por VIH y los costes asociados, en 20 años, en España. El análisis comparó la protocolización del cribado dirigido a personas que presentan alguna condición indicadora (CI) de infección por VIH (diagnóstico de enfermedad de transmisión sexual, síndrome mononucleósido, herpes zóster, neumonía adquirida en la comunidad, práctica del chemsex y profilaxis postexposición) que acuden a los SUH frente a la actual práctica clínica en España en la que el cribado del VIH no está protocolizado. RESULTADOS: El cribado dirigido a personas con alguna CI de VIH en los servicios de urgencias requeriría una inversión de 20 millones de euros en 20 años, pero evitaría 13.615 nuevas infecciones (de 66.265 a 52.650 casos; ­20,6%) comparado con la actual estrategia de diagnóstico. La reducción de la incidencia de VIH supondría unos ahorros potenciales de 4.411 millones de euros en 2 décadas, con un retorno económico de 224 € por euro invertido. CONCLUSIONES: Protocolizar el cribado dirigido a personas con alguna CI de VIH en los SUH en España podría incrementar el diagnóstico, evitar nuevas infecciones de VIH y generar ahorros versus el cribado no protocolizado realizado en la práctica clínica actual.

Large Increase in Azithromycin-Resistant Neisseria gonorrhoeae in Northern Spain.

The aim of this study was to characterize the evolution of gonorrhea in the general population by correlating epidemiological, genotypic, and antimicrobial resistance data of Neisseria gonorrhoeae isolates collected in northern Spain from 2014 to 2018. One hundred ninety-four strains underwent antimicrobial susceptibility testing and were genetically analyzed by N. gonorrhoeae multiantigen sequence typing. Increasing cases of gonococcal infections have been observed after 2015. Most occurred in male with urethritis. Sequence type (ST)-9972 and ST-1576, the predominant genotypes identified, have not been previously described as epidemic clones. Of great concern was the significant increase in azithromycin-resistant N. gonorrhoeae. More than 30% of these isolates were obtained from men who have sex with men (MSM). ST-12302 was the most prevalent clone among the azithromycin-resistant strains, and was also resistant to penicillin, ciprofloxacin, and tetracycline. This multidrug-resistant clone was exclusively isolated from MSM during 2018. The incidence rates of gonorrhea and azithromycin-resistant N. gonorrhoeae have significantly increased due to the emergence of new clones. ST-12302 has recently been recognized as an epidemic clone; therefore, its surveillance could be the key in controlling further dissemination of azithromycin resistance. These data highlight the need to perform local studies to update treatment guidelines and reinforce preventive measures against gonorrhea.
