RESUMO

BACKGROUND: The fear of death is a common experience among healthcare students and professionals that may impact the quality of care provided to patients, particularly those receiving palliative care. The Collett-Lester Fear of Death Scale is a widely used instrument to assess this fear, although its psychometric properties have not been extensively studied in Occupational Therapy students. The present study aimed to validate the Collett-Lester Fear of Death Scale (CL-FODS) in a sample of Occupational Therapy students and to explore its implications for palliative care education. METHOD: A cross-sectional study was conducted to perform psychometric testing of the CL-FODS in Occupational Therapy undergraduate students. Structural validity, internal consistency, and test-retest reliability were analysed. A total of 195 Occupational Therapy students were included in this study. Additionally, the participants completed a brief survey on their experiences and attitudes towards palliative care. RESULTS: The internal consistency was satisfactory (α = 0.888). The exploratory factor analysis to evaluate the internal structure yielded four factors. The model fit indices were: comparative fit index = 0.89, and root mean square error of approximation = 0.06). The test-retest reliability was satisfactory and demonstrated an intraclass correlation coefficient of 0.939. CONCLUSION: The Spanish version of the CL-FODS showed satisfactory psychometric properties; therefore, assessing fear of death in Occupational Therapy students is helpful. This study highlights the importance of addressing fear of death and palliative care education in Occupational Therapy undergraduates to improve future professional attitudes and, consequently, the quality of patient care at the end of life.

RESUMO

Angiogenesis is a fundamental process in biology, given the pivotal role played by blood vessels in providing oxygen and nutrients to tissues, thus ensuring cell survival. Moreover, it is critical in many life-threatening pathologies, like cancer and cardiovascular diseases. In this context, conventional treatments of pathological angiogenesis suffer from several limitations, including low bioavailability, limited spatial and temporal resolution, lack of specificity and possible side effects. Recently, innovative strategies have been explored to overcome these drawbacks based on the use of exogenous nano-sized materials and the treatment of the endothelial tissue with optical or electrical stimuli. Here, conjugated polymer-based nanoparticles are proposed as exogenous photo-actuators, thus combining the advantages offered by nanotechnology with those typical of optical stimulation. Light excitation can achieve high spatial and temporal resolution, while permitting minimal invasiveness. Interestingly, the possibility to either enhance (≈+30%) or reduce (up to -65%) the angiogenic capability of model endothelial cells is demonstrated, by employing different polymer beads, depending on the material type and the presence/absence of the light stimulus. In vitro results reported here represent a valuable proof of principle of the reliability and efficacy of the proposed approach and should be considered as a promising step towards a paradigm shift in therapeutic angiogenesis.

RESUMO

We present the consensus document on the immunization schedule for adolescents developed by 3 scientific societies: the Spanish Association of Pediatrics (AEP), through its Advisory Committee on Vaccines (CAV-AEP), the Spanish Society of Adolescent Medicine (SEMA) and the Spanish Association of Vaccinology (AEV). There are particularities in infectious disease during adolescence, such as an increased susceptibility to pertussis, poorer outcomes of chickenpox, mumps and hepatitis A, a high incidence of sexually transmitted infections or increased prevalence of meningococcal carriage. The document analyses the schedule for adolescents in the context of vaccination policy overall. It contemplates the vaccines to be included in the immunization schedule for healthy adolescents: against invasive meningococcal disease (tetravalent ACWY and B), against human papillomavirus (which should be gender-neutral), against pertussis, against influenza and against SARS-CoV-2 (in unvaccinated individuals and at-risk groups). It is worth noting that the 4CMenB vaccine appears to confer some protection against gonococcal infection, which would be a considerable added value for adolescents. The vaccination of adolescents belonging to risk groups or travelling abroad also needs to be contemplated, as is the case in any other age group. Vaccination against hepatitis A, which is included in the routine immunization schedule of Catalonia, Ceuta and Melilla from the second year of life, should also be considered a priority in adolescents traveling to endemic areas.

RESUMO

INTRODUCTION: Combating physical inactivity and reducing sitting time are one of the principal challenges proposed by public health systems. Gamification has been seen as an innovative, functional and motivating strategy to encourage patients to increase their physical activity (PA) and reduce sedentary lifestyles through behaviour change techniques (BCT). However, the effectiveness of these interventions is not usually studied before their use. The main objective of this study will be to analyse the effectiveness of a gamified mobile application (iGAME) developed in the context of promoting PA and reducing sitting time with the BCT approach, as an intervention of secondary prevention in sedentary patients. METHODS AND ANALYSIS: A randomised clinical trial will be conducted among sedentary patients with one of these conditions: non-specific low back pain, cancer survivors and mild depression. The experimental group will receive a 12-week intervention based on a gamified mobile health application using BCT to promote PA and reduce sedentarism. Participants in the control group will be educated about the benefits of PA. The International Physical Activity Questionnaire will be considered the primary outcome. International Sedentary Assessment Tool, EuroQoL-5D, MEDRISK Instruments and consumption of Health System resources will be evaluated as secondary outcomes. Specific questionnaires will be administered depending on the clinical population. Outcomes will be assessed at baseline, at 6 weeks, at the end of the intervention (12 weeks), at 26 weeks and at 52 weeks. ETHICS AND DISSEMINATION: The study has been approved by the Portal de Ética de la Investigación Biomédica de Andalucía Ethics Committee (RCT-iGAME 24092020). All participants will be informed about the purpose and content of the study and written informed consent will be completed. The results of this study will be published in a peer-reviewed journal and disseminated electronically and in print. TRIAL REGISTRATION NUMBER: NCT04019119.

RESUMO

Breast cancer survivors (BCS) may face functional alterations after surgical intervention. Upper Limb Disorders (ULDs) are highly prevalent even years after a diagnosis. Clinicians may assess the upper limbs after breast cancer. The Upper Limb Functional Index (ULFI) has been validated across different populations and languages. This study aimed to assess the psychometric properties of the Upper Limb Functional Index Spanish version (ULFI-Sp) in the BCS. METHODS: A psychometric validation study of the ULFI-Sp was conducted on 216 voluntary breast cancer survivors. The psychometric properties were as follows: analysis of the factor structure by maximum likelihood extraction (MLE), internal consistency, and construct validity by confirmatory factor analysis (CFA). RESULTS: The factor structure was one-dimensional. ULFI-Sp showed a high internal consistency for the total score (α = 0.916) and the regression score obtained from MLE (α = 0.996). CFA revealed a poor fit, and a new 14-item model (short version) was further tested. The developed short version of the ULFI-SP is preferable to assess upper limb function in Spanish BCS. CONCLUSIONS: Given the high prevalence of ULD in this population and the broader versions of ULFI across different languages, this study's results may be transferred to clinical practice and integrated as part of upper limb assessment after breast cancer.

RESUMO

BACKGROUND: Breast cancer survivors may have side effects from treatment, such as impaired upper limb function after surgery, which may be affected by a range of factors. OBJECTIVE: To analyze the association between upper limb function and strength, fear avoidance, and central sensitization symptoms among breast cancer survivors, and to explore how these variables are associated with upper limb function. DESIGN: Validation cohort. SETTING: Institutional practice at a public hospital. PATIENTS: One hundred seventy-four breast cancer survivors who had been undergone surgery for a primary tumor. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Upper limb function was measured by the Upper Limb Functional Index (ULFI-Sp). Independent outcomes were: handgrip strength, which was measured using a Jamar dynamometer on the dominant side; fear avoidance, measured using the Fear-Avoidance Components Scale (FACS-Sp); and central sensitization symptoms, which were measured using the Central Sensitisation Inventory (CSI-Sp). A linear regression model explaining the ULFI-Sp results was constructed with the variables. RESULTS: The regression model was significant (F = 46.826; p < .0001), and explained 45% of the variance of the ULFI values. All variables showed strong associations with upper limb function. CONCLUSIONS: Greater upper limb function is associated with higher grip strength, lower fear-avoidance behavior and fewer central sensitization symptoms among breast cancer survivors. These variables explained 45% of the upper limb function in the regression model, and concur with earlier research showing that factors such as central sensitization symptoms and kinesiophobia negatively affect upper limb function in such patients. Clinicians should therefore take into account strength, fear avoidance, and central sensitization symptoms when considering interventions aimed at improving upper limb function among breast cancer survivors.

RESUMO

PURPOSE: Palliative care is constantly increasing around the world. The knowledge and skills of future physicians in this area are crucial. This study evaluates the psychometric properties of knowledge and skills questionnaires used in palliative care, validated by physicians or medical students based on the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology. METHODS: A systematic review was carried out in Cosmin Databases, Cochrane Library, PsycINFO, SciELO, Cinahl, and Medline up to September 2020 (updated June 2021), based on the COSMIN methodology and PRISMA recommendations. The psychometric properties of each included questionnaire were identified. Methodological quality, quality of results, and quality of evidence were evaluated. RESULTS: The search strategy yielded 12 questionnaires assessing the knowledge and skills of physicians or medical students. The Palliative Care Knowledge Questionnaire for PEACE (PEACE-Q) and Palliative Care Knowledge Test (PCKT) were the instruments with the highest scores for methodological quality, quality of results, and quality of evidence-based on the COSMIN methodology. CONCLUSIONS: PEACE-Q and PCKT should be the preferred choice to assess palliative care knowledge and skills in physicians. In-depth studies following COSMIN validation criteria are recommended to improve the psychometric properties and cross-cultural validation of the questionnaires.

RESUMO

The increase in life expectancy has led to a growth in the number of people in need of palliative care. Health professionals must possess appropriate knowledge and skills. This study aimed to assess knowledge in palliative care through the Palliative Care Knowledge Test Spanish Version (PCKT-SV)®. A cross-sectional analytical study was conducted in 40 primary care health services. A total of 600 PCKT-SV questionnaires were distributed among health professionals; 561 of them (226 nurses and 335 physicians) were properly filled up. Sociodemographic information, education, and work experience were also recorded. A total of 34.41% of the nurses and 67.40% of the physicians showed good or excellent knowledge of palliative care. Physicians' scores for pain, dyspnea, and psychiatric disorders were higher than those of the nurses. Nurses scored significantly better in philosophy. Professionals with continuous training in palliative care showed a higher level of knowledge. Age and work experience of physicians and undergraduate training in nurses had significant weight in knowledge. Developing continuous training and enhancing undergraduate training in palliative care will lead to improved patient care at the end of life.

RESUMO

Rescue centers remain a common means of rehoming a dog. There is a paucity of research into the composition of rescue center populations and its potential reflection of increased popularity of brachycephalic breeds. The study investigated changes in rescue center demographics from 2015 to 2018, compared to the wider dog population. Dogs on 16 rehoming centers' websites were recorded weekly from June 2015 for 8 weeks and replicated from June 2018. Data were collected on 1793 dogs across the centers. Over 50% of which were classified as purebred in both years. Over 80% of the dogs were categorized into 24 breeds or breed crosses. Dogs categorized as brachycephalic increased from 24 (2.76%) in 2015 to 48 (5.19%) in 2018. Subadult dogs (3-4 years) were most prevalent in both years. While sex, breed type, and age of the rehoming center population has remained relatively stable, breeds are changing. Whilst low, brachycephalic numbers doubled in 3 years, mirroring their rising popularity within the UK, impacting on rehoming centers and prospective new owners with additional costs of brachycephalic obstructive airway syndrome surgery.

RESUMO

This study aimed to analyze the schools that teach ethical and legal aspects within the subject of palliative care in the degrees of medicine and nursing in Spain. MATERIAL AND METHODS: Descriptive Analysis of the palliative care subject and their ethical and legal curricular competencies in the Spanish Nursing and Physicians undergraduate. The training received in legal ethical aspects related to palliative care was compared with the criteria established by the European Association for Palliative Care (EAPC). DATA SOURCES: The National Conference of Nursing Deans, The National Conference of Spanish Medical Faculty Deans and The Ministry of Science, Innovation, and Universities databases were searched. RESULTS: Twenty-one universities have an undergraduate in medicine with palliative care in their curricular training explicitly. The degree in nursing is present in fifty-six universities, palliative care is present in 62.5% of the cases. The degrees of nursing and medicine receive approximately the same level of training in ethical and legal aspects of palliative care. CONCLUSION: The specific training received in ethical and legal issues of palliative care must be improved in medical and nursing to meet the EAPC levels.

RESUMO

INTRODUCTION: Decisions to quit smoking are thought to be influenced by social factors such as friends, family and social groups, but there have been few attempts to examine comprehensively the influence of a range of social factors on smoking cessation. In the largest study to date, we examined whether smoking cessation was associated with marital status and the smoking habits of a partner, socio-economic status and social participation. METHODS: In the prospective Million Women Study, 53,650 current smokers in 2001 (mean age 58.3, SD 4.4) reported their smoking status 4 years later; and reported on social factors on both occasions. Logistic regression yielded odds ratios (ORs) and 99% confidence intervals (CIs) for stopping smoking in the next 4 years by marital status, whether their partner smoked, deprivation, education, and participation in social activities. RESULTS: 31% (16,692) of the current smokers at baseline had stopped after 4 years. Smokers who were partnered at baseline were more likely to quit than those who were not partnered (OR 1.13, 99% CI 1.06-1.19). Compared to having a partner who smoked throughout, those who had a non-smoking partner throughout were more likely to quit (OR 2.01, 99% CI 1.86-2.17), and those who had a partner who smoked at baseline but stopped smoking in the next 4 years were even more likely to quit (OR 6.00, 5.41-6.67). There was no association with cessation for education or deprivation. The association with social participation varied by type of activity but was null overall. CONCLUSION: Women who were partnered were most likely to stop smoking if their partner also stopped smoking. There was little evidence of a strong influence of either socio-economic status or social participation on smoking cessation. These results emphasise the importance of a spouse's smoking habits on the likelihood of a smoker successfully quitting smoking.

RESUMO

Resumen Las cardiopatías congénitas representan un reto diagnóstico para el clínico, sobre todo si su presentación es en el adulto. Las anomalías de este tipo que se observan sobre la válvula mitral pueden presentarse de forma aislada o en conjunto con otros defectos cardiacos. Se expone un caso de hipoplasia severa de la valva posterior de la válvula mitral, entidad que en condiciones normales es fatal antes de nacer o muy sintomática durante la niñez, pero cuya presentación tardía es extremadamente rara y difícil de encontrar en el adulto. Este es el primer caso reportado no solo en nuestro país sino en todo Suramérica.


Abstract The congenital heart diseases are a diagnostic challenge for the clinician, particularly when they are presented in an adult. These types of anomalies that are observed in the mitral valve can be presented in isolated form or together with other heart defects. The case is presented of a patient with severe hypoplasia of the posterior mitral valve leaflet. This anomaly is, under normal conditions, fatal before birth or very symptomatic during childhood, and its delayed presentation is extremely rare and difficult to find in the adult. This the first case reported, not only in this country, but in the whole of South America.

RESUMO

It is generally accepted that the melting point of a semicrystalline polymer is associated with the thickness of the crystalline lamellae (Gibbs-Thomson equation). In this study, a commercially available multiblock copolymer PolyActive composed of 77 wt % of poly(ethylene glycol terephthalate) and 23 wt % of poly(butylene terephthalate) was dip-coated on top of a multilayer microporous support. The thickness was changed between 0.2 and 8 µm using coating solutions containing 0.75-7.5 wt % PolyActive. The surface temperature of the membrane during dip-coating was monitored using an infrared camera. Single gas permeances of N2, H2, CH4, and CO2 were measured between 20 and 80 °C at temperature steps of 2 °C. Spherulitic superstructures composed of radially directed lamellae were observed in the polarized light microscope in the prepared membranes. Atomic force microscopy studies showed that the thickness of the crystalline lamellae was in the order of 10 nm or 0.01 µm at the surface of the membrane. Therefore, according to the Gibbs-Thomson equation, the melting point should not change in the thickness range 0.2-8 µm. However, the gas permeance data showed that the melting point of the polyether domains of the 0.2 µm PolyActive layer was 10 °C lower compared to that of the 8 µm layer. The results can be explained by considering that the width of many crystalline lamellae significantly reduces as a function of film thickness, thereby reducing the average fold surface free energy/lateral surface free energy ratio.

RESUMO

OBJECTIVE: Splenectomy patients have a high risk of suffering severe infections, many of them preventable by vaccination. The aim of the study was to analyse the clinical epidemiological characteristics and vaccine coverage of these patients in Health Area III of the Region of Murcia. METHOD: A cross-sectional study was conducted on a population of patients that were splenectomised during the period 1993-2012, according to the Register of the Basic Minimum Data Set. Patients were classified on the basis of splenectomy (neoplasm, haematological diseases, trauma, and others), vaccination, and vital status, using official records of health data. Statistical analysis was performed using SPSS 21.0 statistics program. RESULTS: The sample consisted of 196 patients, of which 68.4% (n=134) were male. The mean age at which they underwent splenectomy was 50.1 years (SD: 22.2). The most common reason for removal of the spleen was neoplasia in 39.1% (n=59). Splenectomy due to trauma reasons was associated with lower patient age (p<.001) and male gender (p=.03). Vaccination coverage for Streptococcus pneumoniae was 23.8%, 5.7% for Neisseria meningitidis C, and 8.6% for Haemophilus influenzae B. Only 2.9% of patients were correctly vaccinated for all three. CONCLUSIONS: Vaccination coverage was insufficient for this fragile patient profile. It should be taken into account in the early detection and counselling in this group so susceptible to disease, with nurses being a decisive part in the process.

RESUMO

Abstract: Skin disease occur worldwide, affecting people of all nationalities and all skin types. These diseases may have a genetic component and may manifest differently in specific population groups; however, there has been little study on this aspect. If population-based differences exist, it is reasonable to assume that understanding these differences may optimize treatment. While there is a relative paucity of information about similarities and differences in skin diseases around the world, the knowledge-base is expanding. One challenge in understanding population-based variations is posed by terminology used in the literature: including ethnic skin, Hispanic skin, Asian skin, and skin of color. As will be discussed in this article, we recommend that the first three descriptors are no longer used in dermatology because they refer to nonspecific groups of people. In contrast, "skin of color" may be used - perhaps with further refinements in the future - as a term that relates to skin biology and provides relevant information to dermatologists.

RESUMO

INTRODUCTION AND OBJECTIVE: Mediastinal lymph node involvement can be understaged in cases of lung cancer (up to 20% in stage i). Sentinel node detection is a standard technique recommended in breast cancer and melanoma action guidelines, and could also be useful in cases of lung cancer. MATERIAL AND METHODS: Considering the detection of the sentinel node in non-small cell lung cancer (NSCLC) as feasible, a prospective cohort study was carried out on 48 patients with resectable NSCLC, using the intraoperative injection of colloid sulphate technetium-99. RESULTS: The radioisotope migrated in all cases. The procedure's sensitivity was 88.24%, its accuracy was 95.83%, its negative predictive value was 93.94% and the false negative rate was 11.76%. No complications were associated with this technique. CONCLUSIONS: The detection of a sentinel node in NSCLC with the intraoperative injection of the isotope is feasible and safe, and allows for detection and sensitivity rates comparable to those of other tumour types.

RESUMO

T follicular helper cells (Tfh) are critical for the longevity and quality of antibody-mediated protection against infection. Yet few signaling pathways have been identified to be unique solely to Tfh development. ROQUIN is a post-transcriptional repressor of T cells, acting through its ROQ domain to destabilize mRNA targets important for Th1, Th17, and Tfh biology. Here, we report that ROQUIN has a paradoxical function on Tfh differentiation mediated by its RING domain: mice with a T cell-specific deletion of the ROQUIN RING domain have unchanged Th1, Th2, Th17, and Tregs during a T-dependent response but show a profoundly defective antigen-specific Tfh compartment. ROQUIN RING signaling directly antagonized the catalytic α1 subunit of adenosine monophosphate-activated protein kinase (AMPK), a central stress-responsive regulator of cellular metabolism and mTOR signaling, which is known to facilitate T-dependent humoral immunity. We therefore unexpectedly uncover a ROQUIN-AMPK metabolic signaling nexus essential for selectively promoting Tfh responses.

RESUMO

Robot-assisted surgery overcomes some of the limitations of traditional laparoscopic surgery. We present our experience and lessons learned in two surgical units dedicated to gastro-esophageal surgery. From June 2009 to January 2013, we performed 130 robot-assisted gastroesophageal procedures, including Nissen fundoplication (29), paraesophageal hernia repair (18), redo for failed antireflux surgery (11), esophagectomy (19), subtotal (5) or wedge (4) gastrectomy, Heller myotomy for achalasia (22), gastric bypass for morbid obesity (12), thoracoscopic leiomyomectomy (4), Morgagni hernia repair (3), lower-third esophageal diverticulectomy (1) and two diagnostic procedures. There were 80 men and 50 women with a median age of 54 years (interquartile range: 46-65). Ten patients (7.7 %) had severe postoperative complications: eight after esophagectomy (three leaks-two cervical and one thoracic-managed conservatively), one stapler failure, one chylothorax, one case of gastric migration to the thorax, one case of biliary peritonitis, and one patient with a transient ventricular dyskinesia. One redo procedure needed reoperation because of port-site bleeding, and one patient died of pulmonary complications after a giant paraesophageal hernia repair; 30-day mortality was, therefore, 0.8 %. There were six elective and one forced conversions (hemorrhage), so total conversion was 5.4 %. Median length of stay was 4 days (IQ range 3-7). Robot-assisted gastroesophageal surgery is feasible and safe, and may be applied to most common procedures. It seems of particular value for Heller myotomy, large paraesophageal hernias, redo antireflux surgery, transhiatal dissection, and hand-sewn intrathoracic anastomosis.
