Job satisfaction and burnout syndrome among intensive-care unit nurses: A systematic review and meta-analysis.

INTRODUCTION: The severe conditions often experienced in an intensive care unit, combined with poor working conditions, increase stress and therefore decrease job satisfaction. Sustained stress in the workplace leads to the development of burnout, a syndrome characterised by three dimensions: emotional exhaustion, depersonalisation and perceived lack of personal fulfilment. OBJECTIVE: To analyse the relationship between burnout syndrome and job satisfaction among ICU personnel. DATA SOURCES: The PubMed, CINAHL and Scopus databases were used. STUDY DESIGN: A systematic review and meta-analysis. The study sample consisted of 18 quantitative primary studies conducted in the last five years. Validated questionnaires were used to assess burnout in ICU healthcare workers, the most commonly used being the Maslach Burnout Inventory. EXTRACTION METHODS: The search equation applied was: "job satisfaction AND nurs* AND burnout AND (ICU OR intensive care units)". The search was performed in October 2022. PRINCIPAL FINDINGS: The search returned 514 results. Only 73 articles met the eligibility criteria. After reading the title and abstract, 20 articles were selected. After reading the full texts, 12 articles remained and after the reverse search, 18 articles were finally selected. The studies reported a 50% prevalence of burnout, all three dimensions of which were heightened by the COVID-19 pandemic. Analysis of the study findings revealed an inverse association between burnout and job satisfaction. CONCLUSIONS: Job dissatisfaction of ICU nurses depends on lack of experience, working conditions or working environment among others. ICU nurses with lower job satisfaction have higher levels of burnout. IMPLICATIONS FOR CLINICAL PRACTICE: This meta-analysis shows the potential value of job satisfaction on improving health outcomes related to burnout syndrome for nursing professional in Intensive Care Units. Different factors that could increase job satisfaction and consequently protect them from suffering high levels of burnout, such as salary, permanence in the service, mental health care are the responsibility of the hospital supervisor and, finally, of the own Health System. Knowledge of a risk profile based on the factors influencing job dissatisfaction would enable the implementation of effective workplace interventions to reduce or prevent the risk of burnout. Health policies should focus on protecting the worker, so in addition to improving working conditions, it would be interesting to promote coping skills in order to improve the quality of care and patient safety.

Ultrasound-guided peripheral intravenous canulation by emergency nurses: A systematic review and meta-analysis.

BACKGROUND: Peripheral intravenous cannulation is a common procedure in the emergency department. Nevertheless, failure rates during the first attempt are as high as 40% in adults and 65% in children. Evidence suggests that physician performed ultrasound-guided peripheral intravenous cannulation (USG-PIVC) is an effective alternative to the traditional method; however, there is insufficient data on the efficacy of the technique performed by nurses. OBJECTIVE: To examine the efficacy of the USG-PIVC technique performed by emergency department nurses. METHODS: A literature review with meta-analysis was performed. The databases used were PubMed, Scopus and CINAHL. The search was conducted in March 2023. Two meta-analysis one of clinical trials about the effectiveness and one about the succession rate were performed. RESULTS: 20 studies were selected and analysed. The studies showed that USGPIVC performed by emergency nurses increased the probability of both the overall success and a successful first attempt compared to the standard technique. In addition, patients showed high satisfaction and lower complication rates. However, the procedure had no significant effect on the time or number of attempts required. A lower probability of success was obtained as regards peripheral intravenous cannulation when the standard technique was used, OR = 0.42 (95 %CI 0.25-0.70p < 0,05). CONCLUSIONS: Ultrasound-guided peripheral intravenous cannulation performed by emergency nurses is a safe and effective technique.

Cáncer incidental de vesícula: incidencia y factores asociados en pacientes de una institución de la ciudad de Medellín / Incidental gallbladder cancer: Incidence and associated factors in patients from an institution in the city of Medellín

Introducción. El cáncer de vesícula biliar es una de las neoplasias más frecuentes de la vía biliar y la mayoría de los casos se diagnostican de forma incidental o en estadios avanzados. En Colombia existen pocas publicaciones acerca de la prevalencia y características clínicas de pacientes con cáncer insospechado de vesícula biliar. El objetivo de este trabajo fue actualizar la información existente. Métodos. Estudio de tipo transversal basado en registros médicos. Como variable de resultado se definió el hallazgo incidental de patología maligna reportado por un patólogo y el subtipo histológico. Se midieron variables demográficas, clínicas y quirúrgicas. Se calcularon OR con sus respectivos intervalos de confianza (IC95%). Resultados. De los 2630 casos analizados, en cuatro se hizo diagnóstico de cáncer incidental de vesícula, con una prevalencia del 0,15 %. Se encontraron como características asociadas al cáncer incidental de vesícula, la edad, el antecedente de cáncer y la presencia de pólipos. Conclusiones. Esta es una patología poco frecuente en la población evaluada, lo que permite afirmar que no es necesario realizar estudios prequirúrgicos más amplios de forma rutinaria, a menos que el paciente presente alguno de los factores asociados.

Introduction. Gallbladder cancer is one of the most common neoplasms of the bile duct and most cases are diagnosed incidentally or in advanced stages. In Colombia, there are few publications about the prevalence and clinical characteristics of patients with unsuspected gallbladder cancer. The objective of this work was to update the existing information. Methods. Cross-sectional study based on medical records. The incidental finding of malignant pathology reported and the histological subtype were defined as the outcome variable. Demographic, clinical and surgical variables were measured. ORs were calculated with their respective 95% CI. Results. Of the 2630 cases analyzed, four were diagnosed with incidental gallbladder cancer, with a prevalence of 0.15%. Characteristics associated with incidental gallbladder cancer were age, history of cancer and the presence of polyps. Conclusions. This is a rare pathology in the population evaluated, which allows us to recommend that it is not necessary to routinely perform more extensive presurgical studies, unless the patient presents any of the associated factors.

Analyzing Latent Burnout Profiles in a Sample of Spanish Nursing and Psychology Undergraduates.

There is abundant literature suggesting that university students in helping professions experience high levels of stress, leading to an increased risk of developing burnout. The objective of this study was to identify burnout profiles in a sample of 1162 Spanish nursing and psychology undergraduates using latent profile analysis, a person-oriented statistical method that can identify hidden homogenous subgroups within a heterogeneous population. We expected to replicate in university students the five-profile structure (burnout, overextended, disengaged, ineffective, and engagement) proposed by Leiter and Maslach using the burnout dimensions (emotional exhaustion, cynicism, and inefficacy) as indicators. The results showed that burnout, overextended, and engagement profiles were adequately replicated. Given that levels of inefficacy and cynicism were medium to low, the ineffective and disengaged profiles somewhat deviated from those identified by Leiter and Maslach. We found differences between the five latent profiles in several psychological variables, such as depression and anxiety. These results suggest that psychosocial factors (e.g., workload) are significant among students and may adversely impact their health, leading to psychosomatic and emotional disorders. Hence, designing effective interventions to prevent health problems associated with burnout seems advisable, considering the specific burnout profile that a student exhibits.

Robotic surgery in the management of synchronous esophageal and gastric perforation after endoscopic dilation.

Upper gastrointestinal perforation is a feared complication of diagnostic and therapeutic endoscopy, with an incidence of perforation between 0.3% and 5%. Even though is rare, the mortality rate can be as high as 40%. Currently, there is no consensus on the best therapeutic strategy and it usually depends on patient stability, the extent of perforation, time to diagnosis, surgeon experience and available resourcesWe present a case of a patient who presented to our institution to undergo an ambulatory oesophageal dilation. After dilation, the patient developed two full-thickness gastric perforations and a full-thickness oesophageal perforation without haemodynamic instability. All perforations were diagnosed and treated with a combination of intraoperative endoscopy and robotic surgery with excellent outcomes.We demonstrate that a robotic approach combined with intraoperative diagnostic endoscopy is a safe and feasible treatment option for esophageal and gastric perforations in a stable patient without large extraluminal contamination.

Relation and effect of resilience on burnout in nurses: A literature review and meta-analysis.

AIM: To study the relation between burnout and resilience and to identify the profile of nurses presenting this quality. BACKGROUND AND INTRODUCTION: Healthcare professionals are subject to high rates of burnout. Resilience could be an important factor in preventing or alleviating this condition. METHODS: The PubMed, ProQuest, Scopus and ScienceDirect databases were consulted in February 2022 using the equation 'burnout AND resilience AND nurs*'. The inclusion criteria applied were that the texts should describe quantitative studies, be published in English or Spanish, in any year, and be directly related to the question considered. The meta-analysis was performed using StatsDirect statistical software. RESULTS: Analysis of the 29 studies shows that among the dimensions of burnout, nurses are especially prone to emotional exhaustion, and are less affected by depersonalisation and low personal accomplishment. Those who score highly for resilience tend to have longer service experience, acceptable salaries and less work overload. Meta-analysis reveals an inverse correlation between resilience and burnout (r = -0.41; n = 2750), exhaustion (r = -0.27; n = 6966) and depersonalisation (r = -0.23; n = 6115). CONCLUSION: Many nurses present low levels of resilience and suffer from burnout syndrome. The application of programmes to enhance their resilience would help prevent burnout and optimise the potential to provide quality health care. IMPLICATIONS FOR NURSING AND HEALTH POLICY: Resilience is inversely correlated with burnout, depersonalisation and emotional exhaustion. Accordingly, healthcare organisations should develop and implement evidence-based programmes to foster nurses' resilience and thus reduce their susceptibility to burnout.

Synthesis and interaction with growth factors of sulfated oligosaccharides containing an anomeric fluorinated tail.

Compounds that mimic the biological properties of glycosaminoglycans (GAGs) and can be more easily prepared than the native GAG oligosaccharides are highly demanded. Here, we present the synthesis of sulfated oligosaccharides displaying a perfluorinated aliphatic tag at the reducing end as GAG mimetics. The preparation of these molecules was greatly facilitated by the presence of the fluorinated tail since the reaction intermediates were isolated by simple fluorous solid-phase extraction. Fluorescence polarization competition assays indicated that the synthesized oligosaccharides interacted with two heparin-binding growth factors, midkine (MK) and FGF-2, showing higher binding affinities than the natural oligosaccharides, and can be therefore considered as useful GAG mimetics. Moreover, NMR experiments showed that the 3D structure of these compounds is similar to that of the native sequences, in terms of sugar ring and glycosidic linkage conformations. Finally, we also demonstrated that these derivatives are able to block the MK-stimulating effect on NIH3T3 cells growth.

Pleoardoris graminearum, gen. et sp. nov., a new member of Pleosporales from North American Plains, its biogeography and effects on a foundation grass species.

Diverse fungi colonize plant roots worldwide and include species from many orders of the phylum Ascomycota. These fungi include taxa with dark septate hyphae that colonize grass roots and may modulate plant responses to stress. We describe a novel group of fungal isolates and evaluate their effects on the grass Bouteloua gracilis in vitro. We isolated fungi from roots of six native grasses from 24 sites spanning replicated latitudinal gradients in the south-central US grasslands and characterized isolates phylogenetically using a genome analysis. We analyzed 14 isolates representing a novel clade within the family Montagnulaceae (order Pleosporales), here typified as Pleoardoris graminearum, closely related to the genera Didymocrea and Bimuria. This novel species produces asexual, light brown pycnidium-like conidioma, hyaline hyphae, and chlamydospores when cultured on quinoa and kiwicha agar. To evaluate its effects on B. gracilis, seeds were inoculated with one of three isolates (DS304, DS334, and DS1613) and incubated at 25 C for 20 d. We also tested the effect of volatile organic compounds (VOCs) produced by the same isolates on B. gracilis root and stem lengths. Isolates had variable effects on plant growth. One isolate increased B. gracilis root length up to 34% compared with uninoculated controls. VOCs produced by two isolates increased root and stem lengths (P < 0.05) compared with controls. Internal transcribed spacer ITS2 metabarcode data revealed that P. graminearum is distributed across a wide range of sites in North America (22 of 24 sites sampled), and its relative abundance is influenced by host species identity and latitude. Host species identity and site were the most important factors determining P. graminearum relative abundance in drought experiments at the Extreme Drought in the Grasslands Experiment (EDGE) sites. Variable responses of B. gracilis to inoculation highlight the potential importance of nonmycorrhizal root-associated fungi on plant survival in arid ecosystems.

Uremic Toxins Induce THP-1 Monocyte Endothelial Adhesion and Migration through Specific miRNA Expression.

Atherosclerosis is initiated by the activation of endothelial cells that allows monocyte adhesion and transmigration through the vascular wall. The accumulation of uremic toxins such as indoxyl sulphate (IS) and p-cresol (PC) has been associated with atherosclerosis. Currently, miRNAs play a crucial role in the regulation of monocyte activation, adhesion, and trans-endothelial migration. The aim of the present study is to evaluate the effect of IS and PC on monocyte adhesion and migration processes in monocytes co-cultured with endothelial cells as well as to determine the underlying mechanisms. The incubation of HUVECs and THP-1 cells with both IS and PC toxins resulted in an increased migratory capacity of THP-1 cells. Furthermore, the exposure of THP-1 cells to both uremic toxins resulted in the upregulation of BMP-2 and miRNAs-126-3p, -146b-5p, and -223-3p, as well as the activation of nuclear factor kappa B (NF-κB) and a decrease in its inhibitor IĸB. Uremic toxins, such as IS and PC, enhance the migratory and adhesion capacity of THP-1 cells to the vascular endothelium. These toxins, particularly PC, contribute significantly to uremia-associated vascular disease by increasing in THP-1 cells the expression of BMP-2, NF-κB, and key miRNAs associated with the development of atherosclerotic vascular diseases.

Prevalence and levels of burnout in nursing students: A systematic review with meta-analysis.

AIM: The aim of this study was to analyze burnout levels and prevalence in nursing students and to estimate prevalence levels with meta-analyses. BACKGROUND: Nurses are one of the healthcare professionals most affect by burnout, but nursing students, during their studies, can also suffer burnout. DESIGN: a systematic review with meta-analysis was performed. METHODS: The search equation used in Pubmed, CINAHL and Scopus databases was "burnout AND nursing students". Quantitative primary studies including information about burnout, emotional exhaustion, depersonalization, or personal accomplishment in nursing students were included. Four meta-analysis were performed. RESULTS: the sample was of n = 34 studies, with n = 15 studies being included in the meta-analysis with n = 2744 nursing students. Burnout prevalence was 19% (95% CI 11-28%). Regarding burnout dimensions, the most affected was high emotional exhaustion with a prevalence of 41%(95% CI 23-61%; n = 2222) followed by 27% low personal accomplishment(95% CI 9-49%; n = 2096), 25% high depersonalization (95% CI 15-36%; n = 2096). CONCLUSIONS: Prevalence of burnout and its dimensions vary from 19% to 41%, being emotional exhaustion the main problem in nursing students. This problem may affect their future as nursing professionals, and it would be of important to prevent and to treat burnout at university levels.

A Survey of Vectorization Methods in Topological Data Analysis.

Attempts to incorporate topological information in supervised learning tasks have resulted in the creation of several techniques for vectorizing persistent homology barcodes. In this paper, we study thirteen such methods. Besides describing an organizational framework for these methods, we comprehensively benchmark them against three well-known classification tasks. Surprisingly, we discover that the best-performing method is a simple vectorization, which consists only of a few elementary summary statistics. Finally, we provide a convenient web application which has been designed to facilitate exploration and experimentation with various vectorization methods.

Burnout and Professional Engagement during the COVID-19 Pandemic among Nursing Students without Clinical Experience: A Cross-Sectional Study.

Burnout affects many healthcare professionals, especially nurses, causing serious health problems and disrupting the work environment. Academic burnout may also be experienced, leading students to feel unable to cope with their education. As a result, they may lose interest and even consider abandoning their studies. Hence, burnout syndrome can affect both the mental health and the professional future of those affected. To evaluate academic burnout in nursing students who had no clinical experience before starting their practical training, a cross-sectional study involving 212 third-year nursing students at the University of Granada was conducted. Data were collected using the Granada Burnout Questionnaire, the Utrecht Work Engagement Scale, the NEO Five-Factor Inventory, the Hospital Anxiety and Depression Scale, and the Fear of CoronaVirus-19 Scale. High levels of burnout were present in 37.8% of the students. Moreover, 21.5% and 8.7% had borderline cases of anxiety or depression, respectively. Another 30.8% and 9.2%, respectively, were considered likely to present these conditions. According to the predictive models of burnout dimensions obtained, neuroticism is a predictor of all three burnout dimensions. Furthermore, anxiety, depression, extraversion, responsibility and engagement are predictors of some dimensions of the syndrome. Many nursing students present high levels of burnout, which is related to certain personality variables and to the presence of anxiety and/or depression. The level of professional engagement is inversely associated with the impact of burnout. The participants in this study have normalised their return to the pre-pandemic study routine (in-person classes), and fear of COVID-19 was not a significant predictor of any dimension of burnout.

Autonomy with responsibility ¿Is informed consent just a signature on a paper? Evaluation in patients who underwent spine's surgery.

PURPOSE: To evaluate the information that patients undergoing spine surgery truly receive and assimilate when they sign their informed consent documents. METHODS: This was a retrospective study on patients who underwent spine arthrodesis or spine discectomy. Patients were given a full explanation of the surgical technique to be employed and its potential risks before they were included on the surgical waiting list. Before surgery, they were asked to sign an informed consent form. The studied variables included whether patients read the informed consent form, whether they recalled the surgical technique used or the spinal segment operated, whether they were aware of the surgical risks involved, and if they had looked for information about their procedure elsewhere. Answers were analyzed by age and educational level. RESULTS: Of a total of 458 total patients, only 51.9% answered all the questions. Sixty-three percent of patients said they had read the informed consent document before surgery. Although 91.6% of patients were aware of the spine segment operated, only 73.5% remembered the surgical technique employed. A total of 63.9% of patients could recall the vertebral levels operated. 39.1% were not aware of the surgical risks involved, and only 16.0% of patients admitted having looked for additional information. A statistically significant correlation was found between the search for additional information and young age (p < 0.001) on the one hand, and high educational level on the other (p = 0.023). CONCLUSION: Even though obtaining informed consent is an important procedure before spinal surgery, almost 40% of the patients in this study underwent surgery without reading the informed consent document or being aware of the risks posed by the procedure.

Factors related to the appearance and development of burnout in nursing students: a systematic review and meta-analysis.

Introduction: Burnout may be suffered not only by experienced nurses, but also by those in training. The university environment can be highly stressful for student nurses, who are exposed to various stress-producing situations. Aim: The aim of this study is to identify and analyse the main risk factors for burnout among nursing students. Methods: A systematic review with meta-analysis was performed. The search equation used was "Burnout AND Nursing students". Quantitative primary studies on burnout in nursing students, and related risk factors published in English or Spanish and with no restriction by year of publication were included. Results: A sample of n = 33 studies were included. Three variables are identified can influence burnout in nursing students: academic, interpersonal, environmental and/or social factors. The meta-analyses, with the higher sample of n = 418 nursing students, show that some personality factors, empathy, and resilience are correlated with emotional exhaustion, depersonalization and personal accomplishment. Conclusion: The personality factors that can influence the development of burnout in nursing students, such as resilience and empathy, among others, must be taken into account when preventing the appearance and treating burnout. Professors should teach nursing students to prevent and recognize the most frequent symptoms of burnout syndrome.

Improved outcomes over time and higher mortality in CMV seropositive allogeneic stem cell transplantation patients with COVID-19; An infectious disease working party study from the European Society for Blood and Marrow Transplantation registry.

Introduction: COVID-19 has been associated with high morbidity and mortality in allogeneic hematopoietic stem cell transplant (allo-HCT) recipients. Methods: This study reports on 986 patients reported to the EBMT registry during the first 29 months of the pandemic. Results: The median age was 50.3 years (min - max; 1.0 - 80.7). The median time from most recent HCT to diagnosis of COVID-19 was 20 months (min - max; 0.0 - 383.9). The median time was 19.3 (0.0 - 287.6) months during 2020, 21.2 (0.1 - 324.5) months during 2021, and 19.7 (0.1 - 383.9) months during 2022 (p = NS). 145/986 (14.7%) patients died; 124 (12.6%) due to COVID-19 and 21 of other causes. Only 2/204 (1%) fully vaccinated patients died from COVID-19. There was a successive improvement in overall survival over time. In multivariate analysis, increasing age (p<.0001), worse performance status (p<.0001), contracting COVID-19 within the first 30 days (p<.0001) or 30 - 100 days after HCT (p=.003), ongoing immunosuppression (p=.004), pre-existing lung disease (p=.003), and recipient CMV seropositivity (p=.004) had negative impact on overall survival while patients contracting COVID-19 in 2020 (p<.0001) or 2021 (p=.027) had worse overall survival than patients with COVID-19 diagnosed in 2022. Discussion: Although the outcome of COVID-19 has improved, patients having risk factors were still at risk for severe COVID-19 including death.

Congenital Paraduodenal Hernia: A Case Report

Paraduodenal hernia is a rare congenital anomaly that arises from an alteration in the midgut rotation during embryogenesis. Consequently, the small intestine becomes trapped in a sac of the posterior mesentery of the colon. This entity can compromise the intestinal segment's viability and the patient's life. Its diagnosis is difficult, rarely suspected, and often confused with other causes of abdominal pain. We present the case of a 29-year-old male patient with a documented paraduodenal hernia during surgery, its correction, and follow-up, in which no complications were reported.

La hernia paraduodenal es una anomalía congénita poco frecuente que surge de una alteración en la rotación del intestino medio durante la embriogénesis. En consecuencia, el intestino delgado queda atrapado en un saco del mesenterio colónico posterior. Dicha entidad puede comprometer la viabilidad del segmento intestinal y la vida del paciente. Su diagnóstico es difícil, pocas veces sospechado y muchas veces confundido con otras causas de dolor abdominal. Presentamos el caso de un paciente de 29 años con una hernia paraduodenal documentada durante la cirugía, su corrección y seguimiento, en el cual no se documentaron complicaciones.

Normal Infrarenal Aortic Diameter in Men and Women in a Mediterranean Area.

BACKGROUND: Infrarenal aortic diameter (AD) values currently considered normal are based on measurements from epidemiologic studies performed over 20 years ago. Knowledge of expected normal AD is important for understanding the relevance of abdominal aortic dilatation. The aim of this study was to define contemporary reference values for normal infrarenal AD and build a predictive model based on individual features. METHODS: A cross-sectional study of participants in a population-based screening program for abdominal aortic aneurysm (AAA) was performed in a healthcare district with 400,000 inhabitants. Men and women aged 65 years were invited to participate. Cardiovascular (CV) risk factors, family history of AAA, personal history of other aneurysms, CV disease, and anthropometric parameters were evaluated. The largest anteroposterior inner-inner diameter of the infrarenal aorta was measured by ultrasound. Multiple linear regressions were used to determine independent predictors of AD. The best-fit model was obtained by randomly selecting 70% of the sample and validating the results in the remaining 30%. RESULTS: A total of 4,730 people (2,089 men and 2,641 women) were invited. The participation rate was 50.4% for men and 44.0% for women. Mean AD (standard deviation, SD) was 16.51 (3.2) mm in the overall group, 17.91 (3.51) mm in men, and 15.25 (2.32) mm in women (P < 0.001). Male sex (P < 0.001), body surface area (P < 0.001), smoking habit (P = 0.012), and history of arterial aneurysms (P = 0.013) were independently associated with increased AD. Dyslipidemia was associated with decreased AD (P < 0.001). The findings were used to build a model for predicting AD based on individual characteristics. CONCLUSIONS: ADs in our study population are smaller than those described in classic epidemiological studies. Men have a significantly larger diameter than women and the strongest predictor of increased AD is body surface area. A greater understanding of factors associated with AD will help predict expected sizes in individual members of the population.

Long-Term Assessment of a Set of CO2 Concentration Sensors in an In-Use Office Building.

The measurement of the CO2 concentration has a wide range of applications. Traditionally, it has been used to assess air quality, with other applications linked to the experimental assessment of occupancy patterns and air renewal rates. More recently, the worldwide dissemination of COVID-19 establishing a relationship between infection risk and the mean CO2 level has abruptly led to the measurement of the CO2 concentration in order to limit the spread of this respiratory disease in the indoor environment. Therefore, the extensive application of this measurement outside of traditional air quality assessment requires an in-depth analysis of the suitability of these sensors for such modern applications. This paper discusses the performance of an array of commercial wall-mounted CO2 sensors, focusing on their application to obtain occupancy patterns and air renovation rates. This study is supported by several long-term test campaigns conducted in an in-use office building located in south-eastern Spain. The results show a spread of 19-101 ppm, with a drift of 28 ppm over 5 years, an offset of 2-301 ppm and fluctuations up to 80 ppm in instantaneous measurements not related to concentration changes. It is proposed that values averaged over 30 min, using a suitable reference value, be used to avoid erroneous results when calibration is not feasible.
