Nurses' perceptions of preceptorship of undergraduate students in clinical context.

BACKGROUND: Nurses' perceptions of preceptorships for undergraduate nursing students are crucial for designing effective and tailor-made strategies to improve nurses' involvement, motivation, commitment, and satisfaction in preceptorships. OBJECTIVES: The aim of this study was to determine nurses' perceptions of preceptorships for nursing students in two hospitals located in northern Spain. SETTINGS: This study was conducted in two highly specialized, medium-large, university tertiary care hospitals, including one public and one private hospital, located in northern Spain. PARTICIPANTS: The participants of this study were clinical nurses in private and public health centers who had been preceptors for at least one year. METHODS: A descriptive cross-sectional study was carried out between October 2021 and April 2022, with a total sample of 307. The validated "Involvement, Motivation, Satisfaction, Obstacles and Commitment" (IMSOC) questionnaire was used. Descriptive statistics and bivariate analysis were carried out. The variables included sex, age, educational level, preceptorship training, professional experience, work sector, work setting, and type of contract. RESULTS: The mean global questionnaire score was 115.25 ± 33.86 (95 % CI: 111.62-123), with the highest score obtained for the "Involvement" dimension (29.96; SD: 9.23; 95 % CI: 29.01-34.87). Age showed statistically significant negative correlations with the overall and dimension scores (p < 0.05). Comparisons by work sector and type of contract reflected that nurses working in the private sector and those with permanent contracts had higher motivation and commitment scores. CONCLUSIONS: Preceptors had positive perceptions of their role in undergraduate nursing students' education. Age, work sector, type of contract and time allocation should be considered when designing strategies to enhance the involvement, motivation, commitment, and satisfaction of nurses in their experiences as preceptors for undergraduate nursing students. Improving the preceptorship experience will benefit both nurses and students by improving preparation, satisfaction, and retention.

Novel Sb-doped SnO2 ceramic anode coated with a photoactive BiPO4 layer for the photoelectrochemical degradation of an emerging pollutant.

In the present work, a study about the electrochemical and photoelectrochemical degradation of an emerging pollutant using an Sb-doped SnO2 anode coated with a photocatalytic layer of BiPO4 has been performed. The electrochemical characterization of the material was carried out by means of linear sweep voltammetry, light-pulsed chronoamperometry and electrochemical impedance spectroscopy. These studies confirmed that the material is photoactive at intermediate potential values (around 2.5 V), and that the charge transfer resistance decreases in the presence of light. A positive effect of the illuminated area on the degradation degree of norfloxacin was observed: at 15.50 mA cm-2, the degradation rate was 83.37% in the absence of light, 92.24% with an illuminated area of 5.7 cm2, and it increased up to 98.82% with an illuminated area of 11.4 cm2. The kinetics of the process were evaluated, and the by-products of the degradation were identified by ion chromatography and HPLC. In the case of the mineralization degree, the effect of light is less significant, especially at higher current densities. The specific energy consumption of the process was lower in the photoelectrochemical experiments as compared to the experiments in dark conditions. At intermediate current densities (15.50 mA cm-2) a decrease in energy consumption of 53% was achieved by illuminating the electrode.

Differences in intraoperative and surgical outcomes between normotensive pheochromocytomas and sympathetic paragangliomas (PPGLs) and hypertensive PPGLs: results from the PHEO-RISK STUDY.

PURPOSE: To compare the intraoperative and surgical outcomes of normotensive pheochromocytomas and sympathetic paragangliomas (PPGLs), hypertensive PPGLs and non-PPGL adrenal lesions. METHODS: This a retrospective multicenter cohort study of patients with PPGLs from 18 tertiary hospitals. A control group of histologically confirmed adrenocortical adenomas (non-PPGL group) was selected to compare intraoperative and surgical outcomes with of the normotensive PPGLs. RESULTS: Two hundred and ninety-six surgeries performed in 289 patients with PPGLs were included. Before surgery, 209 patients were classified as hypertensive PPGLs (70.6%) and 87 as normotensive PPGLs. A higher proportion of normotensive PPGLs than hypertensive PPGLs did not receive alpha presurgical blockade (P = 0.009). When we only considered those patients who received presurgical alpha blockers (200 hypertensive PPGLs and 76 normotensive PPGLs), hypertensive PPGLs had a threefold higher risk of intraoperative hypertensive crisis (OR 3.0 [95% 1.3-7.0]) and of hypotensive episodes (OR 2.9 [95% CI 1.2-6.7]) than normotensive PPGLs. When we compared normotensive PPGLs (n = 76) and non-PPGLs (n = 58), normotensive PPGLs had a fivefold higher risk of intraoperative complications (OR 5.3 [95% CI 1.9-14.9]) and a six times higher risk of postoperative complications (OR 6.1 [95% CI 1.7-21.6]) than non-PPGLs. CONCLUSION: Although the risk of intraoperative hypertensive and hypotensive episodes in normotensive PPGLs is significantly lower than in hypertensive PPGLs, normotensive PPGLs have a greater risk of intraoperative and postoperative complications than non-PPGL adrenal lesions. Therefore, it is recommended to follow the standard of care for presurgical and anesthetic management of PPGLs also in normotensive PPGLs.

Norfloxacin mineralization under light exposure using Sb-SnO2 ceramic anodes coated with BiFeO3 photocatalyst.

Advanced Oxidation Processes have been proven to be an efficient way to remove organic pollutants from wastewaters. In this work, a ceramic electrode of Sb-SnO2 (BCE) with a layer of the photocatalytic material BiFeO3 (BFO-BCE), has been characterized electrochemically and further tested for norfloxacin photo-electrooxidation in the presence and absence of light. The electrode photoactivity was highly enhanced thanks to the presence of BiFeO3, as confirmed by Linear Sweep Voltammetry, chronoamperometry and potentiometry, and Electrochemical Impedance Spectroscopy. Additionally, working in galvanostatic mode, a high mineralization of norfloxacin was achieved after 240 min, reaching 62% at 25 mA cm-2 under light conditions. This value is comparatively higher than the 40% achieved with the BCE. The oxidation byproducts were followed by ionic chromatography and HPLC analysis, which also allowed us to propose an oxidation pathway of the norfloxacin molecule. Finally, some indicators of the reactor performance such as the Mineralization Current Efficiency and the specific energy consumption were analyzed, revealing that lower current densities (8.3 mA cm-2) led to higher current efficiencies, and that light improved both the current efficiency and energy consumption.

[Update of the recommendations of the Pneumonia Zero project]. / Actualización de las recomendaciones del proyecto Neumonía Zero.

The SARS-Cov-2 pandemic has had a negative impact on the implementation of the Zero Pneumonia recommendations and has been accompanied by an increase in rates of ventilator- associated pneumonia (VAP) in intensive care units in Spain. With the aim of reducing the current rates to 7 episodes per 1000 days of MV, the recommendations of the initial project have been updated.Twenty-seven measures were identified and classified into 12 functional measures (semi- sitting position, strict hand hygiene, airway manipulation training, daily assessment of possible extubation, protocolisation of weaning, early tracheostomy, non-invasive ventilation, microbiological surveillance, tubing change, humidification, respiratory physiotherapy, post- pyloric enteral nutrition), 7 mechanical measures (pneumotap pressure control, subglottic suction tubes, subglottic suctioning of tubes, subglottic suctioning of tubes, post-pyloric enteral nutrition, subglottic suction tubes, small-bore/small-bowel tube nutrition, closed/open circuit secretion suctioning, respiratory filters, tooth brushing, negative pressure techniques for secretion suctioning) and 8 pharmacological (selective digestive decontamination, oropharyngeal decontamination, short course of antibiotics, chlorhexidine mouth hygiene, inhaled antibiotics, antibiotic rotation, probiotics, monoclonal antibodies).Each measure was analysed independently, by at least two members of the working group, through a systematic review of the literature and an iterative review of recommendations from scientific societies and/or expert groups.For the classification of the quality of the evidence and strength of the recommendations, the GRADE group proposal was followed. To determine the level of recommendation, each measure was scored by all members of the working group in relation to its effectiveness, tolerability and applicability in Spanish ICUs in the short term. The support of external experts was requested for some of the measures reviewed. Those measures that achieved the highest score were selected.

[Hand hygiene and pandemic. Controversies]. / Higiene de manos y pandemia. Controversias.

During the COVID-19 pandemic, the world's healthcare systems were extremely strained. Intensive care units were stretched to capacity and healthcare facilities were forced to set up spaces to care for critically ill patients. Professionals were required to work in strenuous conditions, completely disrupting their work routines.In this scenario, hand hygiene and the use of gloves by healthcare professionals became a critical point of transmission risk.The results of the ENVIN study in 2020 and 2021, corresponding to the pandemic period, showed worrying data on the increase in infection rates, with rates rising by 250% at the worst moments of the pandemic. This suggested that excessive risk situations were occurring for the patient. Any preventive strategy must place correct hand hygiene and proper use of gloves among its priority objectives. For this reason, the Project Zero Advisory Board made a series of adaptations and recommendations based on available evidence and expert opinion related to hand hygiene and glove use during the pandemic situation to promote best practice in extreme situations. This article reviews the key aspects of hand hygiene as part of the WHO safety strategy, the main barriers to compliance and the main adaptations proposed by the Advisory Board of the Zero projects.

[Dyadic self-care interventions in chronic heart failure in hospital settings: a systematic review].

Dyadic self-care in chronic heart failure (CHF) is key to ensure treatment continuity, reduce complications and readmissions, and minimise caregiver burden, but it requires specific strategies. The aim of the study was to identify dyadic self-management interventions in CHF in hospital settings by means of a systematic literature review conducted in the Pubmed, CINAHL and PsycInfo databases. Methodological quality was assessed according to CASPe and Joanna Briggs Institute tools. The main components of the interventions were identified: delivery format; dimensions and strategies used (cognitive-attitudinal, affective-emotional and behavioural); providers and recipients; measurement instruments used; and effectiveness. Most of the studies demonstrated improved outcomes, especially in depression and/or anxiety symptoms, adherence to treatment, diet and weight control. Innovative interventions that include components of the three dimensions identified and the use of valid, reliable and specific scales to measure outcomes are recommended.

Delphi consensus on recommendations for the treatment of spinal muscular atrophy in Spain (RET-AME consensus).

INTRODUCTION: Spinal muscular atrophy (SMA) is a neurodegenerative disease caused by a biallelic mutation of the SMN1 gene, located on the long arm of chromosome 5, and predominantly affects the motor neurons of the anterior horn of the spinal cord, causing progressive muscle weakness and atrophy. The development of disease-modifying treatments is significantly changing the natural history of SMA, but uncertainty remains about which patients can benefit from these treatments and how that benefit should be measured. METHODOLOGY: A group of experts specialised in neurology, neuropediatrics, and rehabilitation and representatives of the Spanish association of patients with SMA followed the Delphi method to reach a consensus on 5 issues related to the use of these new treatments: general aspects, treatment objectives, outcome assessment tools, requirements of the treating centres, and regulation of their use. Consensus was considered to be achieved when a response received at least 80% of votes. RESULTS: Treatment protocols are useful for regulating the use of high-impact medications and should guide treatment, but should be updated regularly to take into account the most recent evidence available, and their implementation should be assessed on an individual basis. Age, baseline functional status, and, in the case of children, the type of SMA and the number of copies of SMN2 are characteristics that should be considered when establishing therapeutic objectives, assessment tools, and the use of such treatments. The cost-effectiveness of these treatments in paediatric patients is mainly influenced by early treatment onset; therefore, the implementation of neonatal screening is recommended. CONCLUSIONS: The RET-AME consensus recommendations provide a frame of reference for the appropriate use of disease-modifying treatments in patients with SMA.

The needs of families who care for individuals with kidney failure on comprehensive conservative care: A qualitative systematic review.

BACKGROUND: Integrating the family of patients with kidney failure on comprehensive conservative care could benefit patients, families, and the health care system. However, there is a knowledge gap in this phenomenon since no systematic review has focused on the families' needs who care for individuals with kidney failure on comprehensive conservative care. OBJECTIVES: To understand the primary needs of families who care for people with kidney failure on comprehensive conservative care. METHOD: A systematic literature review of qualitative studies, followed by a content analysis was carried out. PubMed, CINAHL, and PsycINFO databases were used to search for articles published in English and Spanish between 2010 and 2021. The ENTREQ guideline was used for reporting. RESULTS: Five relevant studies were included in this study. The analysis has allowed identifying key aspects of knowledge, psychological, social and spiritual needs of family members of patients with kidney failure on comprehensive conservative care. CONCLUSIONS: This systematic review has revealed that families experience a lack of information and continuity of care by health care professionals. Added to this is the psychological burden they bear due to the feeling of indefinite care in time and uncertainty about the death of their loved one. All this, without the necessary support from their immediate family environment and social institutions. In light of these data, a paradigm shift in society and the health care received by these families is essential.

Nivel de empoderamiento de las personas con insuficiencia cardíaca crónica hospitalizadas / Level of empowerment of hospitalized chronic heart failure patient

Fundamento: Conocer el nivel de empoderamiento de laspersonas con insuficiencia cardiaca crónica hospitalizadas es crucial para identificar a las personas con un nivelde empoderamiento más bajo y fundamentar el diseño deestrategias efectivas para mejorar su control sobre lasdecisiones y acciones que afectan a su salud y bienestar.La falta de estudio de este fenómeno en esta poblacióny contexto, sugiere que estos pacientes no están siendoatendidos adecuadamente. Material y métodos: Estudio descriptivo, prospectivo. Seutilizó el Cuestionario de empoderamiento del pacientecon enfermedad crónica, traducido y validado al español,que consta de 47 ítems, agrupados en tres dimensiones:Actitud positiva y sentido del control, Toma de decisiones compartida e informada, y Búsqueda de informacióny compartir entre iguales. Fue distribuido para su cumplimentación en las 24 horas previas al alta hospitalaria.Resultados: Se recogieron 25 cuestionarios (81%). La puntuación global media de empoderamiento fue de 165,92 ±20,9. La dimensión Actitud positiva y sentido de controlfue la peor puntuada, con una media de 3,4 ± 0,5. Se encontró una relación inversa y débil entre el nivel de em-poderamiento y la edad (rho = -0,240; p = 0,000) y una relación débil y positiva con la supervivencia a los 10 años(rho = 0,316; p = 0,01).Conclusión: El nivel de empoderamiento de los pacientesde este estudio fue medio-alto. Las estrategias para abordar la atención de esta población deberían centrarse entrabajar su actitud respecto a la enfermedad y percepciónde control de la situación e individualizarse conforme ala edad.(AU)

Background: Establishing the level of chronic cardiac inpatient empowerment is essential. By doing so, it is possible to identify groups with a lower level. It also providesa basis for designing effective strategies to improve theircontrol over decision making and the actions that affecttheir health and wellness. The shortage of studies of thisphenomenon for this particular population and contextsuggests that such patients are not receiving proper care. Methods: A prospective and descriptive study was carried out. A validated Spanish version of the Patient empowerment in long-term conditions scale was used. Thesurvey has 47 items, grouped into three dimensions: Positive attitude and feeling of control, Knowledge in shareddecision making, and Seeking information and sharingwith other patients. It was distributed 24 hours beforehospital discharge. Results: Twenty five questionnaires were collected (81%).The mean global empowerment score of the patients was165.92 ± 20.9. The dimension Positive attitude and senseof control showed the lowest score, with a mean of 3.4± 0.5. An inverse weak relationship was found betweenthe level of empowerment and age (rho = -0.240; p = 0.000)while a positive one was found with 10-year survival(rho = 0,316; p = 0.01). Conclusion: The level of empowerment of the patients inthis study was medium-high. The strategies used to address the care of this population should focus on workingon their attitude towards the disease and perceived control of the situation, and should be individualized according to age.(AU)

SEOR SBRT-SG survey on SRS/SBRT dose prescription criteria in Spain

Aim Stereotactic body radiotherapy (SBRT) and stereotactic radiosurgery (SRS) are essential tools in radiation oncology. In Spain, the use of these techniques continues to grow as older linear accelerators (linacs) are replaced with modern equipment. However, little is known about inter-centre variability in prescription and dose heterogeneity limits. Consequently, the SBRT-Spanish Task Group (SBRT-SG) of the Spanish Society of Radiation Oncology (SEOR) has undertaken an initiative to assess prescription and homogeneity in SRS/SBRT treatment. In the present study, we surveyed radiation oncology (RO) departments to obtain a realistic overview of prescription methods used for SBRT and SRS treatment in Spain. Methods A brief survey was developed and sent to 34 RO departments in Spain, mostly those who are members of the SEOR SBRT-SG. The survey contained seven questions about the specific prescription mode, dose distribution heterogeneity limits, prescription strategies according to SRS/SBRT type, and the use of IMRT–VMAT (Intensity Modulated Radiation Therapy–Volumetric Modulated Arc Therapy). Results Responses were received from 29 centres. Most centres (59%) used the prescription criteria D95% ≥ 100%. Accepted dose heterogeneity was wide, ranging from 107 to 200%. Most centres used IMRT–VMAT (93%). Conclusions This survey about SRS/SBRT prescription and dose heterogeneity has evidenced substantial inter-centre variability in prescription criteria, particularly for intended and accepted dose heterogeneity. These differences could potentially influence the mean planning target volume dose and its correlation with treatment outcomes. The findings presented here will be used by the SEOR SBRT-SG to develop recommendations for SRS/SBRT dose prescription and heterogeneity (AU)
