Resumen: Introducción y objetivos: El intervencionismo neurovascular (INV) en la fase aguda del ictus isquémico es una alternativa válida en los casos en que la trombólisis intravenosa está contraindicada o cuando no ha sido efectiva. Nuestro objetivo es presentar la experiencia inicial del INV en la Comunidad de Madrid. Métodos: Registro prospectivo de ictus isquémicos tratados con INV en la Comunidad de Madrid (2005-2009). Se recogen variables epidemiológicas, factores de riesgo y gravedad del ictus mediante la NIHSS (National Institute of Health Stroke Scale). Registramos el tipo de técnica, la situación funcional a los 3 meses, mediante la escala de Rankin modificada (eRm), complicaciones hemorrágicas y mortalidad. Resultados: Se incluyó a 41 pacientes. La media ± desviación estándar de edad fue 58,6 ± 19,9 años; el 56,1%, varones. Hubo 22 pacientes con ictus de circulación anterior y 19, de circulación posterior. La mediana de la puntuación NIHSS basal fue 17 [intervalo, 2-34]; 7 pacientes recibieron trombólisis intravenosa previa. Las técnicas utilizadas fueron: interrupción mecánica (26 pacientes), trombólisis intraarterial (26 pacientes), angioplastia/stent (5 pacientes), extracción mecánica mediante dispositivo MERCI (Mechanical Embolus Removal in Cerebral Ischemia) (3 pacientes). Se consiguió una recanalización parcial o total en 32 pacientes (78%). Un paciente presentó una transformación hemorrágica sintomática (2,4%). Al cabo de 3 meses el 53,6% de los pacientes eran independientes (eRm ≤ 2) y la mortalidad general fue del 19,5%. Conclusiones: El ictus isquémico es una emergencia médica tratable en las primeras horas. El INV es una alternativa terapéutica factible y útil en los casos de contraindicación o ineficacia de la trombólisis intravenosa. Abstract: Background and purpose: Endovascular therapies in acute ischaemic stroke may offer benefits to patients that are not eligible for standard use of intravenous tissue activator plasminogen (iv t-PA) or when this is not effective. Our aim is to present the initial experience in with endovascular techniques in the Community of Madrid. Methods: We present data from our registry of acute ischaemic strokes treated with endovascular re-perfusion therapies in five University Hospitals in Madrid (Spain) during the period 2005-2009. We recorded demographic data, vascular risk factors, risk severity with the NIHSS (National Institute of Health Stroke Scale), endovascular techniques, complications and mortality rates. Functional outcome and neurological disability at 90 days was defined by the modified Rankin scale (mRs). Results: A total of 41 patients were treated with endovascular therapies. Mean age was 58.6 ± 19.9, and 56.1% were males. Of those 22 patients had an anterior circulation stroke and 19 had a posterior circulation stroke. Baseline NIHSS score was: median, 17 [range, 2-34]; 7 patients had previously received iv t-PA. The following endovascular techniques were performed: mechanical disruption (26 patients), intra-arterial infusion of t-PA (26 patients), angioplasty and stenting (5 patients), mechanical use of MERCI device (3 patients). Partial or total re-canalization was achieved in 32 patients (78%). Only one patient had a symptomatic cerebral haemorrhage. Three months after stroke, 53.6% of the patients were independent (mRs ≤ 2) and overall mortality rate was 19.5%. Conclusions: Acute ischaemic stroke is a potentially treatable medical emergency within the first hours after the onset of symptoms. Stroke endovascular procedures constitute an alternative for patients with iv t-PA exclusion criteria or when this is not effective.

Background: Collaborative Online International Learning (COIL) involves international online activities that allow the support of transversal competencies in diverse and multicultural environments without moving from home. This paper presents the learning experiences and satisfaction of undergraduate nursing students at the University of Girona (Spain) from a COIL activity involving clinical simulation in collaboration with the University of Coventry (United Kingdom)., Methods: Qualitative study of content analysis. Twelve students from each of the two universities participated in the data collection process using reflective diaries., Results: The data analysis highlighted five topics related to the COIL activity involving clinical simulation: (a) initial attitudes towards the COIL activity; (b) main learning through the COIL activity; (c) positive aspects of the COIL activity; (d) weaknesses of the COIL activity and proposals for improvement; and (e) overall evaluation of the COIL activity., Conclusions: The main learning outcomes referred to by students were the relationships between transversal competencies and the skills for life, language skills, cultural skills, and more specific skills related to clinical standards. The students were most satisfied with the teaching activities and specified positive aspects and weaknesses that will add value to future versions of the activities.

Background: The experience of chronic low back pain has a significant impact on the quality of life of affected people, resulting in difficulties in performing basic activities of daily living., Aim: To study the perceived quality of life of people affected by chronic low back pain and the associated factors by sex., Methods: A prospective, longitudinal and observational design was used., Results: A total of 129 people (58.1% women) with chronic low back pain were studied. The mean pain intensity scores were of moderate severity (6.42 points), with a modest improvement at follow-up (6.17 points). Epidural nerve blocks were the most effective therapeutic intervention in reducing the intensity of pain. Participants described a negative perception of their health with regard to quality of life, with low scores for the two constructs both at baseline (health index, 0.444; perception of health, 38.76 points) and at follow-up (health index, 0.447; perception of health, 40.43 points). Participants had severe functional limitation scores (50.79 points). The results were significantly better among men. There was an inverse relationship between the average pain intensity (β = -0.304; p < 0.001), functional limitation (β = -0.466; p < 0.001) and mental health (β = -0.565; p < 0.001) and quality of life., Conclusions: The chronification of low back pain complicates people's biopsychosocial adaptation to life. There is a longitudinal inverse association between pain and functional limitation and health-related quality of life.

Background: Aging populations are driving a shift in emphasis toward enhancing chronic disease care, reflected in Catalonia's regional plan which prioritizes standardized nursing care plans in primary care settings. To achieve this, the ARES-AP program was established with a focus on harmonizing standards and supporting routine nursing clinical decision-making. This study evaluates nurses' perceptions of ARES-AP's standardized care plans for chronic diseases., Methods: A mixed-methods approach based on an ad hoc questionnaire (n = 141) and a focus group (n = 14) was used. Quantitative data were statistically analysed, setting significance at p < 0.05. Qualitative data were explored via content analysis., Results: ARES-AP training was assessed positively. The resources for motivational interviewing and care plans for the most prevalent chronic diseases were rated very positively. This study identified key factors influencing program implementation, including facilitators such as structured information and nursing autonomy, barriers such as resistance to change, motivators such as managerial support, and suggested improvements such as technological improvements and time management strategies., Conclusions: This study identifies areas for improvement in implementing standardized nursing care plans, including additional time, motivation, enhanced IT infrastructure, and collaboration among primary care professionals. It enhances understanding of these plans in primary care, especially in managing chronic diseases in aging populations. Further research should assess the program's long-term impact on chronic patients. This study was not registered.

Here we describe a new species of the genus Saccocoelioides found parasitizing Astyanax dissimilis Garavello & Sampaio, Psalidodon bifasciatus (Garavello and Sampaio) and Bryconamericus ikaa Casciotta, Almirón & Azpelicueta from the Iguazu National Park, Misiones province, Argentina. Saccocoelioides miguelmontesi n. sp. was studied based on morphological and molecular (28S rDNA and COI mtDNA sequences) data. The COI mtDNA tree indicated that the specimens collected from the three fish hosts are conspecific, with an intragroup p-distance of 0%. The new species shows an intermediate morphological configuration between the diminutive and robust forms described for Saccocoelioides by Curran (2018). Although, in the 28S rDNA tree, it is placed in a well-supported clade with the two robust species analysed ( S. elongatus and S . magnus ; p-distance of 1 and 2%, respectively), it differs from the robust group by the range of body size, mature egg size, oral and ventral sucker size, sucker ratio, oral sucker to pharynx ratio, and post-cecal or post-testis/body length percentage. Our results led us to redefine the robust group as having eggs shorter or equal in length to the pharynx. Saccocoelioides miguelmontesi n. sp. the 10 th species reported from Argentina and the 7 th species within the robust group.

Background: Informal caregivers are essential figures that deal with the effects of dependence in the elderly. However, they suffer from poorer health-related quality of life, particularly regarding mental health. Social support is crucial, but this was suspended or dramatically reduced during the Covid-19 pandemic. Salutogenesis theory explores the contributing factors for the promotion and maintenance of health. Considering all these, we offered caregivers the opportunity to join a participatory project aimed at creating communication spaces where they could share experiences, think together about potential solutions, and explore which salutogenic actions they used in their daily basis and how they had changed during Covid-19 restrictions., Methods: We used a qualitative methodology with a socio-constructivist and phenomenological approach and purposive sampling. We organized two focus groups consisting of online semi-structured discussions with seven participants in total. Conversations were videotaped and transcribed and we conducted content thematic analyses using the NVivo software., Results: Caregiving in our setting are primarily women with high levels of education that do not always feel comfortable with this load because it interferes with their personal and professional lives. The pandemic increased caregivers feelings of loneliness, resignation, and burden, directly affecting their mental health. Furthermore, the disappearance of prevention programs and the difficulties to access healthcare services produced negative consequences on the already fragile elderly and their family caregivers., Conclusion: The pandemic and its restrictions exacerbated the problematics affecting informal caregivers. Although these people are aware of their situation and have valued knowledge of how to improve their health, they cannot always put it into practice. We call policymakers to reframe interventions aimed at caregivers by introducing the voice of the community in the planning and to rethink the management of vulnerable people and their carers in other potential health crises., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Mas-Casadesús, de la Torre-Pérez, Reig-Garcia, Mas-Casadesús, Berenguera and Juvinyà-Canal.)

Background: Positive mental health (PMH) is a construct used to define and evaluate health from a positive perspective. Healthcare professionals in the emergency ambulance service are more likely to experience mental health disorders than the overall population. The demographic and occupational variables and Sense of Coherence (SOC) can act as predictors of PMH and can serve as protective elements against stress and demanding situations in the work environment., Objective: This study aimed to evaluate PMH and its relationship with demographic and occupational variables and determine if SOC is a predictive variable for PMH in health professionals working in the emergency ambulance service., Methods: A descriptive, cross-sectional, and correlational study was conducted with a sample of 406 healthcare professionals from the emergency ambulance service in eight health regions of Catalonia, Spain. The following variables were analyzed: Age, biological sex, household members, dependents family members, professional category, type of contract, job satisfaction and sense of collaboration with other institutions. The following assessment instruments were used: Positive Mental Health Questionnaire and Sense of Coherence scale., Results: High scores were obtained in Positive Mental Health (PMH). Study participants who reported feeling completely satisfied in their work also showed a significant relationship with all PMH factors: greater satisfaction with their personal life, in their helpful prosocial attitude toward others, in their capability to deal effectively with stress and navigate conflict scenarios, in their ability to solve problems and self-realization, greater empathy and ability to understand the feelings of others, greater ability to establish interpersonal relationships. Comprehensibility, as a dimension of SOC, was identified as a predictor for some factors of PMH: a greater personal satisfaction, self-control, autonomy, interpersonal skills and total PMHQ. More than 43% of positive mental health in health professionals is explained by higher Meaningfulness and Comprehensibility values of the SOC, the absence of dependent family members and having a non-graduate background., Conclusion: Healthcare workers in the emergency ambulance service had high PMH. Meaningfulness (ME) and Comprehensibility (C), dimensions of SOC, were identified as model predictors of greater PMH, showing higher scores in most of PMH factors. To enhance SOC as a mental health promotion measure, resilience programs should be implemented to help professionals develop skills to face and overcome adverse situations. Educating in stress management thought networks are key elements to strengthen SOC. Managers in emergency medical services play a key role in transforming healthcare work environments to promote positive outcomes in the mental health of their healthcare workers., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Background: Several studies have reported the effect of rhythmic auditory stimulation (RAS) on functional ambulation in stroke patients, yet no systematic overview has yet been published. This study aims to synthesize the available evidence describing changes in stroke patients after RAS intervention for functional ambulation and the use of walking assistive devices, and to find out if the effect of RAS and music-based RAS differs depending on the lesioned area., Methods: The PubMed, PEDro, Cochrane Central Register of Controlled Trials, Web of Science, Scopus and CINAHL electronic databases were searched for reports evaluating the effect of RAS on walking in stroke patients, applying the PICOS criteria for the inclusion of studies., Results: Twenty one articles were included (948 stroke survivors). Most studies were of good methodological quality according to the PEDro scale, but they had a high risk of bias. The most consistent finding was that RAS improves walking and balance parameters in stroke patients in all phases compared to baseline and versus control groups with conventional treatment. Functional ambulation and the use of walking assistive devices were inconsistently reported. Several studies also suggest that RAS may be as good as other complementary therapies (horse-riding and visual cueing)., Conclusions: Despite the beneficial effects of RAS, the question remains as to whether it is better than other complementary therapies. Given the heterogeneity of the interventions, the interventions in control groups, the varied durations, and the different outcome measures, we suggest that care should be taken in interpreting and generalizing findings., Prospero Registration: CRD42021277940., (© 2024.

Oral health is crucial for the overall well-being and quality of life, and nurses play a significant role in promoting it. This study assessed the oral health knowledge of fourth-grade nursing degree students. Seventy-two students completed a questionnaire covering sociodemographic variables, oral health-related factors, knowledge about oral health, and perceptions of its importance and learning experiences. The results showed that 83.3% of students attended regular dental check-ups for preventive purposes, and 55.6% had visited a dentist during the last year. Most of the students reported experiencing cavities (66.7%) and undergoing orthodontic treatment (54.2%). The average knowledge score in oral health was 6.4 out of 10, and students recognized the importance of oral health in the nursing role. However, their knowledge acquired during their nursing degree scored relatively low, being 2.5 out of 5. Notably, students who valued problem-based learning achieved higher knowledge scores ( p < 0.05). Overall, fourth-grade nursing students demonstrated a moderate level of oral health knowledge. Improving oral health education within nursing curricula, particularly through problem-based learning, is essential to enhance their preparedness in addressing oral health issues effectively.

The family Bucephalidae is comprised of nine subfamilies, the most important being Bucephalinae with eight genera. Among these, the genus Rhipidocotyle has been found in marine and freshwater environments all over the world. Previous studies of Rhipidocotyle santanaensis have dealt with its morphology or host's ecology. Here, we provide a phylogenetic analysis based on two 28S rDNA sequences from R. santanaensis parasitizing the freshwater fish Acestrorhynchus pantaneiro from the Ibera Lagoon (Corrientes Province, Argentina). The 28S rDNA tree showed that it clustered together with Rhipidocotyle species from Middle and North America, suggesting a common history. Bucephalinae appears to have undergone four evolutionary processes: first, the diversification within the same host family; second, more than one successful infection of the same host family in different geographic regions; third, "jumping" between host families; and, finally, successful invasion of the freshwater environment (occurring in at least four different events in the subfamily). We hypothesize that R. santanaensis entered the freshwater environment by a "jumping" event from some unknown marine host family when a seawater ingression took place in South America during the Late Quaternary. This is the first sequenced Bucephalinae species from South America. Further sequencing will help shed light on the evolutionary relationships between South American members of this group from marine and, especially, freshwater environments., (© 2023.

Motivation: Quantitative descriptions of multi-cellular structures from optical microscopy imaging are prime to understand the variety of three-dimensional (3D) shapes in living organisms. Experimental models of vertebrates, invertebrates and plants, such as zebrafish, killifish, Drosophila or Marchantia, mainly comprise multilayer tissues, and even if microscopes can reach the needed depth, their geometry hinders the selection and subsequent analysis of the optical volumes of interest. Computational tools to "peel" tissues by removing specific layers and reducing 3D volume into planar images, can critically improve visualization and analysis., Results: We developed VolumePeeler, a versatile FIJI plugin for virtual 3D "peeling" of image stacks. The plugin implements spherical and spline surface projections. We applied VolumePeeler to perform peeling in 3D images of spherical embryos, as well as non-spherical tissue layers. The produced images improve the 3D volume visualization and enable analysis and quantification of geometrically challenging microscopy datasets., Availability: ImageJ/FIJI software, source code, examples, and tutorials are openly available in https://cimt.uchile.cl/mcerda., (© 2023.

Background: Most gay men experience difficulty in coming to terms with their sexual orientation, with their health, wellbeing, and quality of life potentially affected by unpleasant experiences often associated with the formation of their gay identity. It is therefore important for nurses to understand the needs of gay men so that they can accompany them and provide quality care during and after the identity formation process., Objective: The aim of the study was to explore and describe the identity formation and coming out experiences of gay men., Methods: A qualitative design with a constructivist naturalist approach was used. Data were collected through in-depth semi-structured interviews with five gay men with experience of the gay identity formation process, and data were analyzed using a thematic analysis method., Results: The results show that the men needed support, as they reported feeling different and alone during the identity formation and coming out process, and that their mental health was affected. Fear of rejection, negative reactions, and disappointing people were the reasons that led the men not to disclose their sexual orientation to family, while those who had come out defined a feeling of liberation., Conclusions: The gay identity formation process has potential impacts on health, wellbeing, and quality of life. Nurses need cultural competence training to be able to understand the needs of gay men, accompany them in the identity formation process, and provide individualized and non-heteronormative care. Nurses also need to participate in dismantling a heterosexist social structure., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)
