Introduction. Monitoring the usage of knowledge and evaluating results permits one to know the application of the evidence, knowledge, and attitude changes, the impact on health results, integration, and maintenance of the adopted practices. There exist weaknesses related to lack of systematization, limitation of the records, and quality of the process. This article's objective is to describe the experience generating monitoring strategies and evaluation of the results regarding the implementation of good practice guides in Spain. Topics for Reflection. In the first place, the measurement process of the results regarding the implementation of guides are reviewed, in the Best Practice Spotlight Organizations® program frame, whose tool to lead the change includes monitoring and evaluation as one of the sixth phases of the action cycle. In the second place, monitoring and evaluation strategies proposed in the literature are analyzed, highlighting the Professional Nurses Association of Ontario. Finally, the monitoring and evaluation strategies are analyzed by two Spanish institutions participating in the program, focused on the adequation of records, exploitation and indicator analysis, tools development, evaluation procedures, dissemination, and feedback mechanisms. Conclusions: The definition of monitoring and evaluation strategies planned in advance contributes to the viability of the evaluation regarding the implementation and its sustainability. Is necessary to adapt them to the context, with transversal strategies that reach the whole institution, facilitated by the institution.

Visceral extra-abdominal panniculitis after COVID19.

"Retractile mesenteritis" was the first name given to a rare, benign, inflammatory disease that affects the adipose tissue of the intestinal mesentery and less frequently other locations. Now labeled as mesenteric panniculitis, the pathogenic mechanism remains unclear. Several stimuli could be involved, and it is sometimes associated with other conditions such as malignancy or autoimmune diseases. We present a case of mesenteric panniculitis with extensive abdominal and extra-abdominal involvement that developed a few months after SARS-COV2 infection, raising the hypothesis of this virus as a potential trigger for autoinflammatory and autoimmune diseases.

Equine infection with Leishmania spp. in Costa Rica: Study of five cases.

BACKGROUND: Cutaneous forms of leishmaniosis due to Leishmania braziliensis have been reported in horses in the New World. Domestic animals play a role in the transmission of the disease. In Costa Rica, human cases of L. braziliensis, L. panamensis and L. infantum have been reported. OBJECTIVES: The present report describes five cases of equine cutaneous leishmaniosis in Costa Rica. The aetiological diagnosis was based on the presence of the parasite within the lesions. METHODS: Skin biopsies were used to perform histopathological analyses of the lesions. Immunohistochemistry was used to detect the presence of the Leishmania spp. antigens in tissue sections. Laser-capture micro-dissection and quantitative real-time PCR techniques were carried out to detect the pathogen nucleic acid within the microscopic lesions. RESULTS: Histopathological analyses showed a granulomatous inflammation within the dermis, with multi-nucleated giant cells, macrophages, lymphocytes and few neutrophils and eosinophils. We detected the parasite by immunohistochemistry, using a rabbit polyclonal antibody raised against Leishmania spp. However, we could not identify Leishmania spp. by quantitative real-time PCR in formalin-fixed paraffin-embedded tissues, using specific primers for the conserved region in the minicircle of the Leishmania DNA kinetoplast. CONCLUSIONS: Our results emphasise the importance of Leishmania spp. not only as a causative agent of equine cutaneous disease in the New World, but also as a possible emerging pathogen. Leishmaniosis is one of the most prevalent parasitic public health problems worldwide, and equines may have a role in the epidemiology of the disease.

[Peritoneal recurrence prediction for colon cancer based on immunoexpression]. / Predicción de recurrencia peritoneal mediante inmunoexpresión en cáncer de colon.

INTRODUCTION AND OBJECTIVES: Peritoneal relapse as an isolated form of recurrence in colon cancer occurs in 25% of cases during the first two years subsequent to a curative colectomy. Currently, the diagnostic limitations of imaging studies and the absence of predictive scales for peritoneal recurrence warrant "second look" surgery in high-risk patients. The aim of this study is to assess features of some epithelial-mesenchymal transition biomarkers (c-Met, IGF-1R and plexin ß1) in order to predict post-surgical peritoneal colonization and develop a mathematical model to predict carcinomatous relapse. METHODS: A retrospective study of the histopathological samples of 87 patients diagnosed with colon cancer who underwent radical resection was carried out, using immunohistochemical techniques for c-Met, IGF-1R and plexin ß1. The patients were divided into two groups; those who had presented peritoneal recurrence and those who only had risk factors for this kind of relapse. Every stained sample was assessed by the rate of stained cells and immunostaining intensity. A possible association between immunohistochemical findings and peritoneal relapse was evaluated. Statistical analysis of the biomarkers with higher prognostic value allowed a risk mathematical formula to be developed based on coefficients, providing a specific value to each biomarker and patient. RESULTS: c-Met expression in the primary tumour showed a high statistical trend (p: .074) while IGF-1 (p: .022) and plexin ß1 (p: .021) revealed a significative association with peritoneal relapse. However, the multivariate analysis selected c-Met y plexin ß1 as useful factors for a predictive mathematical model on peritoneal recurrence with a 75.8% sensitivity and 80.5% specificity in patients with a staining more than 50% for both biomarkers. CONCLUSION: c-Met and plexin B1 overexpression is related to an increased risk of peritoneal relapse in cases of colon cancer where a radical resection is feasible. The encouraging outcomes of the proposed mathematical model may prove useful clinically in the identification of candidates for carcinoprophylaxis.

Phosphorylation in Novel Mitochondrial Creatine Kinase Tyrosine Residues Render Cardioprotection against Hypoxia/Reoxygenation Injury.

OBJECTIVE: Ischemic cardiomyopathy (ICM) is the leading cause of heart failure. Proteomic and genomic studies have demonstrated ischemic preconditioning (IPC) can assert cardioprotection against ICM through mitochondrial function regulation. Considering IPC is conducted in a relatively brief period, regulation of protein expression also occurs very rapidly, highlighting the importance of protein function modulation by post-translational modifications. This study aimed to identify and analyze novel phosphorylated mitochondrial proteins that can be harnessed for therapeutic strategies for preventing ischemia/reperfusion (I/R) injury. METHODS: Sprague-Dawley rat hearts were used in an ex vivo Langendorff system to simulate normal perfusion, I/R, and IPC condition, after which the samples were prepared for phosphoproteomic analysis. Employing human cardiomyocyte AC16 cells, we investigated the cardioprotective role of CKMT2 through overexpression and how site-directed mutagenesis of putative CKMT2 phosphorylation sites (Y159A, Y255A, and Y368A) can affect cardioprotection by measuring CKMT2 protein activity, mitochondrial function and protein expression changes. RESULTS: The phosphoproteomic analysis revealed dephosphorylation of mitochondrial creatine kinase (CKMT2) during ischemia and I/R, while preserving its phosphorylated state during IPC. CKMT2 overexpression conferred cardioprotection against hypoxia/reoxygenation (H/R) by increasing cell viability and mitochondrial adenosine triphosphate level, preserving mitochondrial membrane potential, and reduced reactive oxygen species (ROS) generation, while phosphomutations, especially in Y368, nullified cardioprotection by significantly reducing cell viability and increasing ROS production during H/R. CKMT2 overexpression increased mitochondrial function by mediating the proliferator-activated receptor γ coactivator-1α/estrogen-related receptor-α pathway, and these effects were mostly inhibited by Y368A mutation. CONCLUSION: These results suggest that regulation of quantitative expression and phosphorylation site Y368 of CKMT2 offers a unique mechanism in future ICM therapeutics.

Blood culture-negative infective endocarditis: a worse outcome? Results from a large multicentre retrospective Spanish cohort study.

BACKGROUND: To assess the impact of blood cultures negative infective endocarditis (BCNIE) on in-hospital mortality. METHODS: Prospective multicentre study with retrospective analysis of a Spanish cohort including adult patients with definite IE. Cardiac implantable devices infection were excluded. Comparisons between blood cultures positive and BCNIE groups were performed to analyse in-hospital mortality. RESULTS: 1001 cases were included of which 83 (8.3%) had BCNIE. Alternative microbiological diagnosis was achieved for 39 (47%) out 83 cases. The most frequent identifications were: Coxiella burnetii (11; 28.2%), Tropheryma whipplei (4; 10.3%), Streptococcus gallolyticus (4;10.3%) and Staphylococcus epidermidis (3; 7.7%). Surgery was performed more frequently in BCNIE group (57.8 vs. 36.9%, p < .001). All-cause in-hospital mortality rate was 26.7% without statistical difference between compared groups. BCNIE was not associated to worse mortality rate in Cox regression model (aHR = 1.37, 95% CI 0.90-2.07, p = .14). Absence of microbiological diagnosis was also not associated to worse in-hospital prognosis (aHR = 1.62, 95% CI 0.99-2.64, p = .06). CONCLUSIONS: In our cohort, BCNIE was not associated to greater in-hospital mortality based in multivariate Cox regression models. The variables most frequently associated with mortality were indicated but not performed surgery (aHR = 2.48, 95% CI 1.73-3.56, p < .001), septic shock (aHR = 2.24, 95% CI 1.68-2.99, p < .001), age over 65 years (aHR = 1.88, 95% CI 1.40-2.52, p < .001) and complicated endocarditis (aHR = 1.79, 95% CI 1.36-2.37, p < .001).

Asociación entre Artritis Reumatoidea y otras enfermedades autoinmunes / Association between Rheumatoid Arthritis and other autoimmune diseases

Objetivos: Determinar la frecuencia de enfermedades autoinmunes (EAI) en pacientes con Artritis Reumatoidea (AR) y comparar la frecuencia de EAI entre pacientes con AR y sin AR ni otra EAI reumatológica. Material y Métodos: Estudio multicéntrico, observacional, analítico, retrospectivo. Se incluyeron pacientes consecutivos con AR (ACR/EULAR 2010) y como grupo control pacientes con diagnóstico inicial de Osteoartritis primaria (OA). Resultados: Se incluyeron 1549 pacientes: 831 con AR (84% mujeres, edad media 55.2 años [DE 13.6]) y 718 con OA (82% mujeres, edad media 67 años [DE 11.1]). La frecuencia de EAI en el grupo AR fue del 22% (n=183). Estos presentaron mayor frecuencia de EAI reumatológicas (9.4 vs 3.3%, p< 0.001), y menor frecuencia de EAI no reumatológicas que aquellos con OA (15.3 vs 20.5, p=0.007). La EAI reumatológica más prevalente fue el Síndrome de Sjögren, el cual fue más frecuente en el grupo AR (87.2 vs 29.2%, p< 0,001). La frecuencia de EAI reumatológicas en los pacientes con AR fue mayor en la forma erosiva (11 vs 6.8%, p=0.048). Conclusión: La frecuencia de EAI en los pacientes con AR fue del 22%, en quienes predominaron las de etiología reumatológica mientras que, las no reumatológicas predominaron en pacientes con OA.

Objectives: To determine the frequency of autoimmune diseases (AID) in Rheumatoid Arthritis (RA) patients and to compare this frequency between patients with and without RA or other rheumatologic AID. Methods: Multicenter, observational, analytical, retrospective study. Consecutive patients with diagnosis of RA (ACR/EULAR 2010) were included. Patients with initial diagnosis of primary ostearthritis (OA) were used as control group. Results: A total of 1549 patients were included: 831 RA (84% women, mean age 55.2 [±13.6]) and 718 OA (82% women, mean age 67 [± 11.1]). The frequency of AID in the RA group was 22% (n=183). RA patients showed higher frequency of rheumatologic AID (9.4 vs 3.3%, p< 0.001), and lower frequency of non-rheumatologic AID than OA patients (15.3 vs 20.5%, p= 0.007). The most prevalent rheumatic AID was Sjögren's Syndrome, which was more frequent in the AR group (87.2 vs 29.2%, p<0.001). The frequency of rheumatologic AID in RA patients was higher in those with erosive RA (11 vs 6.8%, p=0.048). Conclusion: The frequency of AID in RA patients was 22%. Rheumatologic AID were more frequent in RA patients, whereas non-rheumatologic AID prevailed in OA patients.

Clinical and prognostic differences between methicillin-resistant and methicillin-susceptible Staphylococcus aureus infective endocarditis.

BACKGROUND: S. aureus (SA) infective endocarditis (IE) has a very high mortality, attributed to the age and comorbidities of patients, inadequate or delayed antibiotic treatment, and methicillin resistance, among other causes. The main study objective was to analyze epidemiological and clinical differences between IE by methicillin-resistant versus methicillin-susceptible SA (MRSA vs. MSSA) and to examine prognostic factors for SA endocarditis, including methicillin resistance and vancomycin minimum inhibitory concentration (MIC) values > 1 µg/mL to MRSA. METHODS: Patients with SA endocarditis were consecutively and prospectively recruited from the Andalusia endocarditis cohort between 1984 and January 2017. RESULTS: We studied 437 patients with SA endocarditis, which was MRSA in 13.5% of cases. A greater likelihood of history of COPD (OR 3.19; 95% CI 1.41-7.23), invasive procedures, or recognized infection focus in the 3 months before IE onset (OR 2.9; 95% CI 1.14-7.65) and of diagnostic delay (OR 3.94; 95% CI 1.64-9.5) was observed in patients with MRSA versus MSSA endocarditis. The one-year mortality rate due to SA endocarditis was 44.3% and associated with decade of endocarditis onset (1985-1999) (OR 8.391; 95% CI (2.82-24.9); 2000-2009 (OR 6.4; 95% CI 2.92-14.06); active neoplasm (OR 6.63; 95% CI 1.7-25.5) and sepsis (OR 2.28; 95% CI 1.053-4.9). Methicillin resistance was not associated with higher IE-related mortality (49.7 vs. 43.1%; p = 0.32). CONCLUSION: MRSA IE is associated with COPD, previous invasive procedure or recognized infection focus, and nosocomial or healthcare-related origin. Methicillin resistance does not appear to be a decisive prognostic factor for SA IE.

A pathological study of Leishmania infantum natural infection in European rabbits (Oryctolagus cuniculus) and Iberian hares (Lepus granatensis).

In this study, we describe the pathology of Leishmania infantum infection in naturally infected wild Leporidae and compare diagnosis of infection using histopathology, direct fluorescent antibody (DFA) assay, immunofluorescence antibody test (IFAT) and quantitative real-time PCR (qPCR). Tissues were analysed from 52 European rabbits (Oryctolagus cuniculus) and 7 Iberian hares (Lepus granatensis) from the Community of Madrid (Spain). Our results show that L. infantum infection is associated with only minimal histopathological lesions and that L. infantum amastigotes can be detected by DFA assay in all tissues types tested, including skin. These results were confirmed by qPCR on fresh frozen tissues in 13% of rabbits and 100% of hares. However, L. infantum DNA could not be detected by qPCR on paraffin-embedded tissue obtained by laser capture microdissection. Using the DFA assay to diagnose L. infantum, infection may provide further insights into this disease in wild animals and may allow the precise tissue localization of L. infantum, thereby guiding follow-up tests with more accurate qPCR.

Evaluation of Learned Helplessness, Perceived Self-efficacy, and Functional Capacity in Patients With Fibromyalgia and Rheumatoid Arthritis.

OBJECTIVES: The aims of this study were to compare learned helplessness (LH) and perceived self-efficacy (SE) in patients with fibromyalgia (FM) and rheumatoid arthritis (RA) and to assess their correlation with functional disability, level of perceived pain, and fatigue. METHODS: This multicenter, cross-sectional study included consecutive patients (aged ≥18 years) with RA, according to the 2010 American College of Rheumatology/European League Against Rheumatism criteria, and FM, according to 2010 American College of Rheumatology criteria. Learned helplessness was measured by the Rheumatology Attitude Index, Spanish version; SE with the Arthritis Self-efficacy Scale, Spanish version; functional capacity with the Health Assessment Questionnaire (HAQ), Argentine version; depression with Center for Epidemiological Studies-Depression Scale 7-item version and perceived pain and fatigue by the visual analog scale. Disease activity was measured by the Clinical Disease Activity Index (CDAI) and disease impact with the Fibromyalgia Impact Questionnaire (FIQ). RESULTS: A total of 215 patients, 100 with FM and 115 with RA, were included. Mean age was 59 (SD, 14) years and 58 (SD, 13) years for FM and RA, patients respectively. Whereas LH and depression were significantly higher, SE was significantly lower in FM patients. We found a positive correlation between LH and HAQ, pain, depression, fatigue, FIQ, and CDAI in FM and RA patients. We observed a negative correlation between SE and HAQ, pain, depression, fatigue, FIQ (FM), and CDAI (RA) in both groups. CONCLUSIONS: Both LH and SE correlate significantly with functional capacity, perceived pain, disease activity, and disease impact in RA and FM patients. Learned helplessness was higher in patients with active disease or high disease impact, as opposed to those in remission or with low disease impact, and the reverse was true for SE. Patients with FM had significantly more LH, pain, fatigue, and depression and less SE compared with those with RA.

Epidemiología de las enfermedades periodontales en el Uruguay. Pasado y presente / Epidemiology of periodontal diseases in Uruguay: past and present

El objetivo del artículo fue realizar una revisión sobre la Enfermedad Periodontal en Uruguay. Fueron consultadas bases de datos internacionales (PUBMED, SCOPUS, EBSCO, SciELO). Paralelamente la búsqueda abarcó fuentes nacionales (Biblioteca Nacional de Odontología, Centro de documentación de la Facultad de Odontología, Ministerio de Salud Pública, Dirección Nacional de Sanidad de las Fuerzas Armadas), complementado por búsqueda manual. Los estudios hallados aportaron información epidemiológica útil, además de permitir un repaso histórico sobre conceptos de epidemiología, etio-patogenía y corrientes hegemónicas de la periodoncia. La Enfermedad Gingival representa la patología más prevalente, mientras que los cuadros periodontales destructivos afectan fundamentalmente a los adultos. La edad, el origen geográfico, la clase social y el hábito de fumar son indicadores fuertemente asociados con dichos trastornos. De la lectura pormenorizada de los artículos recopilados se plantean sugerencias a ser consideradas en los próximos relevamientos epidemiológicos.

This article aims to review periodontal disease in Uruguay. International databases (PUBMED, SCOPUS, EBSCO, SciELO) were consulted. The search also included national sources (National Library of Dentistry, Documentation Center of the School of Dentistry, Ministry of Public Health, National Directorate of Health of the Armed Forces) which were searched manually. The studies found provided useful epidemiological information and allowed us to conduct a historical review of epidemiology concepts, etiopathogenesis and hegemonic currents in periodontics. Gingival disease is the most prevalent disease, while destructive periodontal conditions mainly affect adults. Age, geographical origin, social class and smoking are indicators strongly associated with these disorders. From the close reading of the articles collected we can make suggestions to be considered in future epidemiological surveys

Drug use prevention projects in schools in Vitória, Brazil: quality analysis and improvement proposals

Abstract Adolescents living in vulnerable regions are more exposed to risk factors for drug use. The prevention of such use in school is a public policy that needs evaluation. Based on technical criteria and derived from a mixed research, this article analyses the quality of school-based prevention of drug use in Vitória, state of Espírito Santo, Brazil, and proposes improvements. A checklist of quality elements was completed with data from 16 projects proposed by 99 teachers from public schools. In 10 projects (62.5%), the approximate quality index was above 0.50. The majority of projects fulfilled the requirement of theoretical foundation (81.25%) and some of the methodological (93.75%), design (75%) and implementation (62%) requirements. Other requirements were absent: the majority were not designed by the whole school community (87.5%), and the participation of the family (62.5%) or the students as mediators (62.5%) was not considered. In general, contents of life skills (87.5%), positive relationships and alternative activities to drug use (56.25%) were not included. Activities for reinforcing the content were not described in any of the projects, and evaluation activities were described in only a few (31.25%). Many projects did not describe the inclusion of the project in the school curriculum (62.5%). Although, considering all items of effectiveness, regardless of their weight, more than half of the projects had an above average quality. The present items provide quality to the projects, whereas absent items indicate shortcomings to be improved using some of the measures described in this study.

Aceites esenciales: una opción quimioterapéutica en Periodoncia / Essential-oils: a chemotherapeutic option in periodontics

Las enfermedades periodontales representan un conjunto de patologías que afectan los tejidos de soporte dentario. La remoción del biofilm diaria y efectiva es suficiente para prevenirlas. La dificultad de los individuos en desarrollar hábitos de higiene oral adecuados valiéndose solamente de elementos mecánicos llevó al desarrollo de coadyuvantes químicos con el objetivo de maximizar el control del biofilm por el paciente. Los aceites esenciales son eficaces y superiores en el control de la placa supragingival y la inflamación en comparación con placebo y cloruro de cetilpiridinio. Sin embargo, fueron similares en el control de la inflamación e inferiores en el control de placa en comparación con la clorhexidina, generando menos efectos adversos. La evidencia sugiere que para el cuidado oral a corto plazo la clorhexidina es la primera opción y que los aceites esenciales muestran utilidad al ser indicados a largo plazo cuando el cuidado oral antiinflamatorio sea beneficioso.

Periodontal diseases are a group of pathologies that affect the tissues that support teeth. The efficient control of daily oral biofilm can prevent these diseases. Most individuals have difficulty in developing good oral hygiene habits and use only mechanical elements. This has led to the development of chemical adjuvants so that patients can maximize biofilm control. Essential oils (EOs) are effective and more efficient at controlling supragingival plaque and inflammation compared to a placebo and to cetylpyridinium chloride. Nevertheless, EOs were similar in their anti-inflammatory effectiveness and less efficient in plaque control than chlorhexidine, causing fewer adverse effects. Current evidence suggests that chlorhexidine remains the first choice for short-term oral health care and that essential-oils are best indicated for long-term treatments.

[Expression of gamma interferon during HPV and Chlamydia trachomatis infection in cervical samples]. / Expresión de interferón gamma en la infección por el virus del papiloma humano y por Chlamydia trachomatis en muestras cervicales.

INTRODUCTION: The aim of this study was to mesure the expression of gamma interferon in HPV and Chlamydia trachomatis infection in squamous intraepithelial lesions. METHOD: Samples from 100 patients diagnosed by colposcopy with or without squamous intraepithelial lesions were used in the present study. Each patient was found to be infected by HPV and C.trachomatis. Relative gamma interferon mRNA expression was assessed using a real-time reverse transcriptase PCR assay (RT-PCR). RESULTS: The relative units of expression of gamma interferon mRNA were 13, 1.8 and 0.3, for HPV and C.trachomatis co-infection, or HPV or C.trachomatis infection, respectively. CONCLUSION: HPV and C.trachomatis could overstimulate the expression of gamma interferon.

Association of inflammatory and oxidative stress biomarkers in subjects with cardiovascular risk.

Cardiovascular disease is originated in the vascular endothelium, which controls the homeostasis and the filtration and diffusion of molecules from blood to the tissues. The classical cardiovascular risk factors (CRFs) act directly on the endothelium through an increase in the production of reactive oxygen species, promoting an endothelial activation mediated by the expression of adhesion and proinflammatory molecules, which lead to endothelial dysfunction, the progression of the atherosclerotic plaque, and the onset of cardiovascular disease. The objective of this study was to analyze the association of superoxide dismutase, catalase, gluthatione peroxidase, and lipoperoxidation with fibrinogen, interleukin (IL)-6, tumor necrosis factor-α, and vascular cell adhesion molecule (VCAM)-1 in subjects with cardiovascular risk (CVR) and CRF. This was a cross-sectional study of 114 individuals; oxidative stress (superoxide dismutase, catalase, gluthatione peroxidase, and lipoperoxidation) and inflammatory (fibrinogen, IL-6, tumor necrosis factor-α, and VCAM-1) biomarkers were measured; a CVR score (Framingham) and its CRF were taken into consideration to classify the participants. Twenty-nine subjects out of a total of 114 had high CVR. Smokers and subjects with diabetes (43 subjects) were excluded from the low CVR group. Significant decreases in lipoperoxidation, IL-6, and VCAM-1 and an increase in SOD were found in the high CVR group (P ≤ 0.05). Individual analysis of each CRF in the 114 subjects revealed a different pattern in the biomarkers' statistical differences. Concluding that the biomarkers show statistical differences in each CRF, especially IL-6, VCAM-1, and SOD; therefore, these are highly recommended to be used as biomarkers of the oxidative stress and inflammatory status in CVR.

Síndrome de burnout y enfermería. Evidencia para la práctica / Infirmary and Burnout Syndrome. Evidence in the Practice Nursing

Resumen

Introducción: es reconocido que el trabajo de enfermería en el contexto hospitalario, el estrés tiene diversas fuentes y repercusiones en la salud física y mental de las enfermeras. Los efectos del estrés laboral se han descrito como síndrome de burnout (sb), por lo que en este trabajo se analizan los elementos involucrados en el problema.

Desarrollo: se presenta la evidencia científica sobre los factores que originan el sb: situacionales (características del trabajo, ocupacionales y organizacionales); individuales: (características sociodemográficas, de personalidad y actitudes hacia el trabajo) y la violencia hacia las enfermeras como un factor emergente. Se presenta la evidencia sobre las consecuencias en las enfermeras y en las instituciones, así como las intervenciones que han mostrado efectividad a nivel individual (intervenciones educativas y psicosociales) y a nivel organizacional.

Conclusiones: para la práctica es crucial que las enfermeras administradoras y el personal conozcan todo lo relativo al sb para prevenirlo e intervenir oportunamente. En investigación es prioritario construir una línea que supere las diferencias metodológicas que limitan comparaciones de prevalencia, factores relacionados y consecuencias en el contexto nacional. Es prioritario incluir la evaluación de intervenciones.

Abstract

Introduction: ¡t is recognized that nursing work in the hospital setting has several sources of stress with implications for nurses' physical and mental health. The effects of work stress have been described as Burnout syndrome (BS), so this paper examines the elements involved in the problem.

Development: it presents the scientific evidence on the factors causing the BS: situational (job characteristics, occupational and organizational), individual (sociodemographic characteristics, personality and attitudes to work) and violence towards nurses as an emerging factor. It presents evidence on the impact on nurses and the institutions and interventions that have shown effectiveness at the individual level (education and psychosocial interventions) and at organizational level.

Conclusions: for daily practice it is very important that manager nurses and staff know all about BS to prevent and intervene promptly. Research priority is to build a line that overcomes the methodological differences that limit comparisons of prevalence, associated factors and consequences in the national context. To include evaluation of interventions is a preponderant issue.

[New trends in the treatment of post-operative pain in general and gastrointestinal surgery]. / Nuevas tendencias en el tratamiento del dolor postoperatorio en cirugía general y digestiva.

The correct application of multimodal analgesia appropriate to the pain intensity, the characteristics of the surgery and the hospitalisation scheme provide the key to improving the management of postoperative pain, which is currently still under treated. In highly complex surgeries the best benefit is obtained by combining systemic analgesic drugs with regional analgesia techniques. Epidural analgesia, not only provides an excellent quality of analgesia, but can prevent complications and reduce postoperative morbidity. Recently, peripheral blocks and parietal infiltration techniques, with or without catheter, have gained prominence in the postoperative analgesia of haemorrhoids and hernia repair. All these analgesic techniques are integrated into the concept of early postoperative rehabilitation and pursue the objective of minimising the side effects associated with the treatment and facilitate the functional recovery of the patient. In addition, proper postoperative pain management, not only increases the quality of in-patient care but is also a factor to consider in the development of chronic post-surgical pain, where the impact is significant and impairs the quality of life of the patients.
