RESUMO

Intensive Care to facilitate Organ Donation (ICOD) consists of the initiation or continuation of intensive care measures in patients with a devastating brain injury (DBI) in whom curative treatment is deemed futile and death by neurological criteria (DNC) is foreseen, to incorporate organ donation into their end-of-life plans. In this study we evaluate the outcomes of patients subject to ICOD and identify radiological and clinical factors associated with progression to DNC. In this first prospective multicenter study we tested by multivariate regression the association of clinical and radiological severity features with progression to DNC. Of the 194 patients, 144 (74.2%) patients fulfilled DNC after a median of 25 h (95% IQR: 17-44) from ICOD onset. Two patients (1%) shifted from ICOD to curative treatment, both were alive at discharge. Factors associated with progression to DNC included: age below 70 years, clinical score consistent with severe brain injury, instability, intracranial hemorrhage, midline shift ≥5 mm and certain types of brain herniation. Overall 151 (77.8%) patients progressed to organ donation. Based on these results, we conclude that ICOD is a beneficial and efficient practice that can contribute to the pool of deceased donors.

RESUMO

Most haptic actuators available on the market today can generate only a single modality of stimuli. This ultimately limits the capacity of a kinaesthetic haptic controller to deliver more expressive feedback, requiring a haptic controller to integrate multiple actuators to generate complex haptic stimuli, with a corresponding complexity of construction and control. To address this, we designed a haptic controller to deliver several modalities of kinaesthetic haptic feedback using a single actuator: a flywheel, the orientation of which is controlled by two gimbals capable of rotating over 360 degrees, in combination with a flywheel brake. This enables the controller to generate multiple haptic feedback modalities, such as torque feedback, impact simulation, low-frequency high-amplitude vibrations, inertial effects (the sensation of momentum), and complex haptic output effects such as the experience of vortex-like forces (whirl effects). By combining these diverse haptic effects, the controller enriches the haptic dimension of VR environments. This paper presents the device's design, implementation, and characterization, and proposes potential applications for future work.

RESUMO

BACKGROUND: The utilization of non-lung organs from deceased donors with a positive polymerase chain reaction (PCR) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the time of donation can be lifesaving, although the safety of this policy must be assessed. METHODS: This is a nationwide, prospective study, reporting the experience on the utilization of non-lung organs from SARS-CoV-2-positive donors between December 15, 2020 and May 31, 2022 in Spain. RESULTS: A total of 69 patients received a solid organ transplant (41 kidney, 18 liver, 8 heart, and 2 combined liver-kidney) obtained from 32 donors with a positive SARS-CoV-2 PCR at the time of donation (four of them with a cycle threshold value <30). All recipients tested negative for SARS-CoV-2 and were free of coronavirus disease 2019 (COVID-19) symptoms prior to transplantation. Nasopharyngeal swab turned positive for SARS-CoV-2 PCR in 4 (5.8%) recipients at 3, 8, 11, and 20 days after transplantation, though evidence did not support a donor-derived COVID-19. Four kidney recipients lost their grafts and two patients died: one heart recipient due to cardiogenic shock and one combined liver-kidney recipient due to lung hypertension and right heart failure. Graft losses and patient deaths were deemed unrelated to the donor SARS-CoV-2 status by the treating teams. No other adverse reactions were reported. CONCLUSIONS: This preliminary experience supports the safety of the use of organs other than lungs from SARS-CoV-2 PCR-positive donors, in alignment with previous series. However, the impact of SARS-CoV-2 infection upon organ quality should be established in future research.

RESUMO

The aim of this study was to quantify weekly internal workload across the in-season and compare the workload variables between starter and non-starter Spanish female first league (Liga Iberdrola) football players. Twenty-six participants belonging to the same team (age, height, and mass: 25.4 ± 6.1 years, 167.4 ± 4.8 cm and 57.96 ± 6.28 kg, respectively) participated in this study. Training loads (TL) and match loads (ML) were assessed through breath-cardiovascular (RPEbreath), leg-musculature (RPEleg) and cognitive (RPEcog) rating of perceived exertion (RPE0-10) for each training session and match during the in-season phase (35 weeks). Session-RPE (sRPE) was calculated by multiplying each RPE value by session duration (minutes). From these, total weekly TL (weekly TL+ML), weekly TL, weekly ML, chronic workload, acute:chronic workload ratio, training monotony, and training strain were calculated. Linear mixed models were used to assess differences for each dependent variable, with playing time (starter vs non-starter players) used as a fixed factor, and athlete, week, and team as random factors. The results showed that total weekly TL (d = 1.23-2.04), weekly ML (d = 4.65-5.31), training monotony (d = 0.48-1.66) and training strain (d = 0.24-1.82) for RPEbreath, RPEleg and RPEcog were higher for starters in comparison with non-starters (p = 0.01). Coaches involved in elite female football should consider implementing differential sRPE monitoring strategies to optimize the weekly load distribution for starters and non-starters and to introduce compensatory strategies to equalise players' total weekly load.

RESUMO

The Readiness for Interprofessional Learning Scale (RIPLS) has been widely used to measure students' and professionals' attitudes toward interprofessional learning. However, inconsistencies have been reported concerning its validity and reliability. This study aimed to translate, adapt, and validate the RIPLS questionnaire to be applied to Spanish-speaking health sciences students in Chile. Content and construct validity evidence of the newly created Spanish version of the RIPLS scale were analyzed. An exploratory (EFA) and confirmatory (CFA) analysis were conducted, determining goodness-of-fit indexes. Reliability was evaluated through Cronbach's Alpha Coefficient. We assessed sensitivity to change of the RIPLS scale by comparing pre- and post-interprofessional education workshop scores. The EFA showed that there were three factors. In the CFA, most of the standardized factor loadings were higher than 0.3. Regarding internal consistency, Cronbach's Alpha was 0.86. The differences between the total RIPLS scores before and after the workshops were statistically significant. The Spanish version of RIPLS showed evidence of validity and reliability for use amongst health sciences students. The construct was adequately measured and was shown that it could be used to assess the impact of interprofessional education workshops.

RESUMO

Normothermic regional perfusion (NRP) allows the in situ perfusion of organs with oxygenated blood in donation after the circulatory determination of death (DCDD). We aimed at evaluating the impact of NRP on the short-term outcomes of kidney transplants in controlled DCDD (cDCDD). This is a multicenter, nationwide, retrospective study comparing cDCDD kidneys obtained with NRP versus the standard rapid recovery (RR) technique. During 2012-2018, 2302 cDCDD adult kidney transplants were performed in Spain using NRP (n = 865) or RR (n = 1437). The study groups differed in donor and recipient age, warm, and cold ischemic time and use of ex situ machine perfusion. Transplants in the NRP group were more frequently performed in high-volume centers (≥90 transplants/year). Through matching by propensity score, two cohorts with a total of 770 patients were obtained. After the matching, no statistically significant differences were observed between the groups in terms of primary nonfunction (p = .261) and mortality at 1 year (p =  .111). However, the RR of kidneys was associated with a significantly increased odds of delayed graft function (OR 1.97 [95% CI 1.43-2.72]; p < .001) and 1-year graft loss (OR 1.77 [95% CI 1.01-3.17]; p = .034). In conclusion, compared with RR, NRP appears to improve the short-term outcomes of cDCDD kidney transplants.

RESUMO

Percutaneous coronary intervention (PCI) has long remained the gold standard therapy to restore coronary blood flow after acute myocardial infarction (AMI). However, this procedure leads to the development of increased production of reactive oxygen species (ROS) that can exacerbate the damage caused by AMI, particularly during the reperfusion phase. Numerous attempts based on antioxidant treatments, aimed to reduce the oxidative injury of cardiac tissue, have failed in achieving an effective therapy for these patients. Among these studies, results derived from the use of vitamin C (Vit C) have been inconclusive so far, likely due to suboptimal study designs, misinterpretations, and the erroneous conclusions of clinical trials. Nevertheless, recent clinical trials have shown that the intravenous infusion of Vit C prior to PCI-reduced cardiac injury biomarkers, as well as inflammatory biomarkers and ROS production. In addition, improvements of functional parameters, such as left ventricular ejection fraction (LVEF) and telediastolic left ventricular volume, showed a trend but had an inconclusive association with Vit C. Therefore, it seems reasonable that these beneficial effects could be further enhanced by the association with other antioxidant agents. Indeed, the complexity and the multifactorial nature of the mechanism of injury occurring in AMI demands multitarget agents to reach an enhancement of the expected cardioprotection, a paradigm needing to be demonstrated. The present review provides data supporting the view that an intravenous infusion containing combined safe antioxidants could be a suitable strategy to reduce cardiac injury, thus improving the clinical outcome, life quality, and life expectancy of patients subjected to PCI following AMI.

RESUMO

AIM: To evaluate nursing governance in intermediate care in Catalonia Spain and propose improvements. BACKGROUND: Drawing on two existing models, the Magnet model and the corporate governance model, we propose that good nursing governance requires nursing leaders to apply the following dimensions: transformational leadership, transformational culture, commitment and sustainability, authority, scientific evidence, transparency and communication, and teamwork. METHOD: A qualitative, exploratory study conducted in two phases. First, we asked nursing leaders in intermediate care to describe their opinions and experiences in each of the dimensions. Next, we observed governance practices at two intermediate care centres and conducted interviews with their nursing leaders. Content analysis was used. RESULTS: Our participants' behaviour corresponded closely to the model in the dimensions of transformational culture and commitment and sustainability but failed to meet the model in the dimensions of scientific evidence and transparency and communication. CONCLUSIONS: Participants had a leadership style focused on transforming their surroundings. According to the model, the leaders in our sample should draw more on scientific evidence and improve their internal communication about outcomes. IMPLICATIONS FOR NURSING MANAGEMENT: Establishing committees of nurses to address areas in which governance does not adhere to the model would create sustainable benefits for patients and nurses in intermediate care.

RESUMO

Adolescent characteristics of young adult soccer players (n = 35) were compared with those of youth teammates (n = 124) no longer involved in soccer. Former U-13 players active in soccer as young adults were slightly later in maturation and performed better in several functional and soccer skills than youth teammates. Former U-15 players active in soccer as young adults did not differ in maturity status from youth teammates but were chronologically older and performed better in agility and ball control. Young adult regional and national players in both age groups were rated significantly higher on the potential for success by their youth coaches, and national players were rated significantly higher than regional players. The results highlight the need for study of interactions among coaches, youth training and playing environments and the growth, maturity, functional, skill and behavioural characteristics of youth players, and how these interactions may influence persistence in soccer and later playing status.

RESUMO

Caribbean countries are experiencing social, epidemiological, and demographic transitions shaped by the growing elderly population and the rise of noncommunicable diseases (NCDs)-now responsible for 78% of all deaths. These circumstances demand rethinking the model of care to improve health outcomes and build more sustainable health systems with new orientations in policy, service delivery, organization, training, technology, and financing. Policy must be aimed towards healthy living, leveraging interventions that ensure healthy aging. The health system must proactively structure interventions to reduce the incidence of new NCD cases and to prevent related complications. Interventions should be focused on optimizing the individual's capacity, functional ability, and autonomy within adapted environments, as well as with the necessary preventive, long-term care, self-care, community care, and health system support.


Los países del Caribe están experimentando transiciones sociales, epidemiológicas y demográficas como resultado del envejecimiento de la población y el aumento de la prevalencia de las enfermedades no transmisibles (ENT), que en la actualidad causan el 78% de todas las defunciones. Estas circunstancias exigen replantear el modelo de atención para mejorar los resultados de salud y establecer sistemas de salud más sostenibles mediante nuevos enfoques en políticas, prestación de servicios, organización, capacitación, tecnología y financiamiento. Las políticas deben tener como propósito procurar una vida saludable, aprovechando las intervenciones que garanticen el envejecimiento saludable. El sistema de salud debe ser proactivo, estructurando las intervenciones para reducir la incidencia de nuevos casos de ENT y para prevenir las complicaciones relacionadas. Las intervenciones deben centrarse en optimizar la capacidad funcional, la autonomía y el desenvolvimiento general de la persona dentro de un entorno adaptado y con el apoyo necesario del sistema de salud en materia de atención preventiva, cuidados a largo plazo, de autocuidado y de atención en la comunidad.


Os países do Caribe estão passando por transições sociais, epidemiológicas e demográficas configuradas pela população de idosos cada vez maior e a ascensão das doenças não transmissíveis (DNTs), já responsáveis por 78% de todas as mortes. Essas circunstâncias exigem repensar o modelo de atenção para melhorar os desfechos de saúde e construir sistemas de saúde mais sustentáveis, com novas orientações de política, prestação de serviços, organização, treinamento, tecnologia e financiamento. As políticas devem ser orientadas para a vida saudável, alavancando intervenções que asseguram o envelhecimento saudável. O sistema de saúde deve estruturar proativamente intervenções para reduzir a incidência de novos casos de DNT e a prevenir as complicações relacionadas. As intervenções devem se concentrar na otimização da capacidade do indivíduo, das habilidades funcionais e da autonomia dentro de ambientes adaptados, e também nas ações preventivas a para assistência de longa duração, no autocuidado, na atenção na comunidade e no apoio pelos sistemas de saúde.

RESUMO

BACKGROUND: The ethical values of nursing are crucial to the provision of humane care. Human dignity is a core value that must be preserved in order to deliver such care. No studies to date have compared the perceptions of nurses and/or patients regarding the components of dignified care embedded in actual clinical practice. PURPOSE: To explore the delivery of dignified care by professional nurses. This was an ethnographic qualitative study combining inductive and deductive methods to identify emergent themes. A multicenter study carried out in the internal medicine units of four hospitals in Barcelona (Spain). Convenience sampling was used to recruit nurses from the four units. SETTING AND SAMPLE: Multicenter study carried out in the internal medicine units of four hospitals in Barcelona (Spain). Convenience sampling was used to recruit nurses from the four units. METHOD: We conducted 158 hours of participant observation of 27 nurses. Semi-structured individual interviews were undertaken with 20 of these nurses, with data saturation being reached. Data were collected between September 2014 and May 2016 and were analysed using ATLAS.ti 7.2 for Windows. RESULTS: Two themes emerged from the analysis: Delivering dignified care and Factors influencing the delivery of dignified care. The nurses regarded human dignity as one of the key values of their profession. However, there was a discrepancy between their perceptions of the care they offered and what they actually did, due mainly to a lack of awareness about their own practice. Respect, confidentiality, privacy and communication were identified as the key elements underpinning dignified care. Institutional policies were seen as the major obstacle to the delivery of humane care, the key issues being frequent shift rotations, a high patient-nurse ratio and excessive paperwork. CONCLUSIONS: The results of this study underline the importance of delivering dignified care and the need to ensure that nurses' attitudes and behaviours are consistent with this goal. The ethnographic approach, combining participant observation with individual interviews, revealed discrepancies between nurses' perceptions of the care they offered, or should offer, and what they actually did. This suggests a need for professional forums in which nurses can become more aware of their own clinical practice.

RESUMO

The chemical bulk reductive covalent functionalization of thin-layer black phosphorus (BP) using BP intercalation compounds has been developed. Through effective reductive activation, covalent functionalization of the charged BP by reaction with organic alkyl halides is achieved. Functionalization was extensively demonstrated by means of several spectroscopic techniques and DFT calculations; the products showed higher functionalization degrees than those obtained by neutral routes.

RESUMO

The objective of this document is to describe the steps in the development of the country node of the Virtual Campus for Public Health (VPHC) in Venezuela, with a view to enhancing continuing education in virtual learning environments and strengthening the abilities and knowledge of health workers, which was defined as a national priority. Eliminating geographical barriers, offering flexible schedules, and providing opportunities for real-time, low-cost interaction with experts were key aspects of the development of the Venezuela node. The VPHC nodes offered by the Pan American Health Organization (PAHO), both at the regional and country levels, allow for large-scale training of health workers. However, despite similarities in public health issues at the global and regional levels, each country has specific needs according to its epidemiological, political, social, and economic situation, and has to respond to needs identified at the local level. In Venezuela, the focus is on strengthening competencies and providing continuing education to the 13 921 basic health teams deployed in the country's 24 states. It was in this context that the PAHO country office supported the development of the Venezuela node of the VPHC.


O objetivo desta análise é descrever os passos no desenvolvimento do núcleo país do Campus Virtual de Saúde Pública (CVSP) na Venezuela. Incentivar a educação contínua em espaços virtuais de aprendizagem, reforçar habilidades e conhecimentos dos profissionais da saúde definido como prioridade nacional, eliminar barreiras geográficas e proporcionar horários flexíveis e a possibilidade de interação em tempo real com especialistas a um baixo custo foram aspectos destacados para o desenvolvimento do núcleo na Venezuela. Os núcleos do CVSP, tanto regionais como nos países, propiciados pela Organização Pan-Americana da Saúde (OPAS), permitem a formação em massa de profissionais da saúde. No entanto, apesar das semelhanças em saúde pública nas esferas global e regional, os países têm necessidades próprias de acordo com a situação epidemiológica, política, social e econômica e precisam atender as necessidades identificadas ao nível local. Na Venezuela, o enfoque de fortalecimento das competências e a formação contínua dos profissionais da saúde é direcionado às 13 921 equipes básicas de saúde implantadas nos 24 estados do país. Diante desta realidade, a repartição da OPAS no país deu apoio ao desenvolvimento do núcleo Venezuela do CVSP.

RESUMO

BACKGROUND: The acquisition of experience is a major concern for nurses in intensive care units. Although the emotional component of the clinical practice of these nurses has been widely studied, greater examination is required to determine how this component influences their learning and practical experience. OBJECTIVE: To discover the relationships between emotion, memory and learning and the impacts on nursing clinical practice. RESEARCH DESIGN: This is a qualitative phenomenological study. The data were collected from open, in-depth interviews. A total of 22 intensive care unit nurses participated in this research between January 2012 and December 2014. Ethical considerations: The School of Nursing Ethics Committee approved the study, which complied with ethical principles and required informed consent. FINDINGS: We found a clear relationship between emotion, memory and the acquisition of experience. This relationship grouped three dimensions: (1) satisfaction, to relieve the patient's pain or discomfort, give confidence and a sense of security to the patient, enable the presence of family members into the intensive care unit and provide family members with a realistic view of the patient's situation; (2) error experience, which nurses feel when a patient dies, when they fail to accompany a patient in his or her decision to abandon the struggle to live or when they fail to lend support to the patient's family; and (3) the feel bad-feel good paradox, which occurs when a mistake in the patient's care or handling of his or her family is repaired. CONCLUSION: Emotion is a capacity that impacts on nurses' experience and influences improvements in clinical practice. Recalling stories of satisfaction helps to reinforce good practice, while recalling stories of errors helps to identify difficulties in the profession and recognise new forms of action. The articulation of emotional competencies may support the development of nursing ethics in the intensive care unit to protect and defend their patients and improve their relationships with families in order to maximise the potential for patient care.

RESUMO

Prediction of symptomatic crises in chronic diseases allows to take decisions before the symptoms occur, such as the intake of drugs to avoid the symptoms or the activation of medical alarms. The prediction horizon is in this case an important parameter in order to fulfill the pharmacokinetics of medications, or the time response of medical services. This paper presents a study about the prediction limits of a chronic disease with symptomatic crises: the migraine. For that purpose, this work develops a methodology to build predictive migraine models and to improve these predictions beyond the limits of the initial models. The maximum prediction horizon is analyzed, and its dependency on the selected features is studied. A strategy for model selection is proposed to tackle the trade off between conservative but robust predictive models, with respect to less accurate predictions with higher horizons. The obtained results show a prediction horizon close to 40min, which is in the time range of the drug pharmacokinetics. Experiments have been performed in a realistic scenario where input data have been acquired in an ambulatory clinical study by the deployment of a non-intrusive Wireless Body Sensor Network. Our results provide an effective methodology for the selection of the future horizon in the development of prediction algorithms for diseases experiencing symptomatic crises.

RESUMO

Migraine is one of the most wide-spread neurological disorders, and its medical treatment represents a high percentage of the costs of health systems. In some patients, characteristic symptoms that precede the headache appear. However, they are nonspecific, and their prediction horizon is unknown and pretty variable; hence, these symptoms are almost useless for prediction, and they are not useful to advance the intake of drugs to be effective and neutralize the pain. To solve this problem, this paper sets up a realistic monitoring scenario where hemodynamic variables from real patients are monitored in ambulatory conditions with a wireless body sensor network (WBSN). The acquired data are used to evaluate the predictive capabilities and robustness against noise and failures in sensors of several modeling approaches. The obtained results encourage the development of per-patient models based on state-space models (N4SID) that are capable of providing average forecast windows of 47 min and a low rate of false positives.

RESUMO

OBJECTIVE: Explore and transform dialogic-reflexive learning processes oriented to self-care, capacitation, empowerment and health promotion for "mature-adult" collective. DESIGN: Participative action research on a qualitative and sociocritic approach. Data generation methods are SITE: Field work focuses on the development of the educational program "Care is in your hands" that takes place in two villages (Primary Care. Comarca Araba). PARTICIPANTS: Through a theoretical sampling involved people who are in a "mature-adult" life stage and three nurses with extensive experience in development health education programs. METHODS: Participant observation where health education sessions are recorded in video and group reflection on action. To triangulate the data, have been made in-depth interviews with 4 participants. Carried out a content and discourse analysis. RESULTS: Participant and nurses' Previous Frameworks, and these last ones' discourses as well, reveal a current technical rationality (unidirectional, informative,.) yet in practice that perpetuates the role of passive recipient of care. Educational keys constructed from a viewpoint of Dialogic Learning emerge as elements that facilitate overcoming these previous frames limitations. Finally, Reflective Learning launched, has provided advance in professional knowledge and improve health education. CONCLUSIONS: Dialogical learning emerges as key to the training and empowerment, where we have seen how practical-reflexive, and not technical, rationality is meanly useful confronting ambiguous and complex situations of self-care practice and education.

RESUMO

The Region of the Americas has been affected since December 2013 by a chikungunya epidemic for the first time. Although the first cases were recorded in the French Caribbean, the epidemic quickly spread to the Dominican Republic due to trade and people movements. The Dominican Republic, which shares the island of Hispaniola with Haiti, has a population of 10 million. This article contains information from a range of different publications and official documents about the chikungunya virus infection and epidemic. These papers were extremely helpful for guiding the response to the epidemic in the Dominican Republic and may also be useful for enhancing knowledge of the virus and responses among health workers elsewhere in the region. Particular attention is drawn to the important research undertaken in countries and territories affected by the epidemic in the Indian Ocean area. This is the case, for example, of the island of La Réunion, where the epidemic had an attack rate of more than 30% between 2005 and 2007. Researchers were able to identify risk groups, severe and atypical forms of the infection, cases of vertical transmission, chronic disease causing recurrent pain over three years, and directly- or indirectly-related deaths from the virus. Given its high attack rate, the chikungunya virus has emerged as an exceptional challenge for health ministries and calls for appropriate organized responses from the health services, prioritization of care for risk groups and patients exhibiting severe forms of the disease, and effective social communication and intersectoral actions.

RESUMO

The chikungunya epidemic in the Dominican Republic began in February 2014. During the first six months 429 421 cases were recorded, representing 65% of all those notified to the Pan American Health Organization by 33 countries and territories of the Region of the Americas. This epidemic has spread quickly in the Dominican Republic, requiring a focused intersectoral response, led by the Ministry of Public Health and involving major efforts by the National Epidemiological System and the health services network. Given that the virus will affect thousands of people, this article seeks to describe the actions that have already been carried out, and to share the results and lessons learned during these first months with health ministries and professionals in the countries of the Region, in order to assist them to prepare an appropriate response to confront the epidemic effectively and efficiently.
