Adaptation and validation of the Physical Restraint-Theory of Planned Behaviour Questionnaire to the paediatric context.

BACKGROUND: Physical restraint is applied in pediatric intensive care units to carry out certain painful procedures and to ensure the maintenance and continuity of life support devices. There is a need to analyse the factors that influence the behaviour or intention to use physical restraint. AIM: To create and test psychometrically a paediatric version of the Physical Restraint-Theory of Planned Behaviour Questionnaire to assess paediatric critical care nurses' intention to use physical restraint. STUDY DESIGN: A psychometric study. Five medical-surgical Paeditric Intensive care Units from five hospitals in Spain. The study took place in three phases. In phase 1, the questionnaire was adapted. In phase 2, the content validity of each item was determined, and a pilot test was conducted. In phase 3, we administered the questionnaire and determined its psychometric properties. RESULTS: The assessment of the intention to use physical restraint was extended to all critical paediatric patients, two items were eliminated from the initial questionnaire, four new items were included, and the clinical scenarios of the intention subscale were expanded from three to six. Overall content validity index for the full instrument of 0.96 out of 1. The Paediatric Physical Restraint-Theory of Planned Behaviour Questionnaire is made up of four subscales (attitude, subjective norms (SN), perceived behavioural control (PBC), and intention) subdivided into 7 factors and 51 items. The internal consistency for the attitude subscale obtained a Cronbach's Alpha of 0.80 to 0.73, for the SN it was 0.72 to 0.89, for the PBC it was from 0.80 to 0.73 and for the intention subscale it was 0.75. CONCLUSIONS: The Paediatric Physical Restraint-Theory of Planned Behaviour Questionnaire is an instrument composed of seven factors and 51 items that validly and reliably assesses the intention of paediatric nurses to apply PR in PICUs. RELEVANCE FOR CLINICAL PRACTICE: Having this instrument will help health centres move towards restraint-free care by allowing managers to assess professionals' attitudes, beliefs, and intentions around the use of PR in PICUs.

Pedigree analysis in the mhorr gazelle (Nanger dama mhorr): Genetic variability evolution of the captive population.

Breeding programs have an essential role in the recovery of threatened populations through optimal genetic management and mating strategies. The dama gazelle (Nanger dama) is a North African ungulate listed as critically endangered. The mhorr subspecies is extinct in the wild and currently survives thanks to the creation in 1971 of an ex situ breeding program. The aim of the present study was to assess the evolution of genetic variability in this mhorr gazelle captive population, as well as the mating strategy used in two reference populations studied (Almeria and Europe). The entire pedigree, with 2739 animals, was analyzed to measure demographic characters, pedigree completeness level, probability of gene origin, level of relatedness and genetic structure of the population. The population size has been progressively increasing, with up to 264 individuals alive in Europe at the time of the study. The average number of equivalent complete generations was 5.55. The effective number of founders and ancestors was both 3, and the founder genome equivalent was 1.99. The genetic contributions of the four main ancestors were unbalanced. The average values of inbreeding and average relatedness for the whole pedigree were, respectively, 28.34% and 50.14%. The effective population size was 8.7 by individual increase in inbreeding and 9.8 by individual increase in coancestry. F-statistics evidenced a very small level of population subdivision (F ST = 0.033370). The mating strategy used, based on the minimum coancestry of the individuals, has minimized the losses of genetic variability and helped to balance the genetic contributions between ancestors. The strategy also avoided large subdivisions within the population and the appearance of new bottlenecks. This study shows how pedigree analysis can both be used to determine the genetic variability of the population and to assess the influence of the mating strategy used in the breeding program on such variability.

Prevalence of use of physical restraints in pediatric intensive care units and correlated variables: A Spanish multicenter study.

OBJECTIVE: To calculate the prevalence of physical restraint (PR) use in Spanish PICUs and (2) to analyze the correlation between the prevalence of PR use and the sociodemographic, clinical variables of the patients and the PICU structural and organizational variables. METHODS: We conducted a multicenter prevalence study from January 2022 to January 2023 in Spanish PICUs. The method of data collection was by direct observation, review of the patient's medical history, and asking the professionals involved in the patient's care. Three weekly 24-hour prevalence observations (morning, afternoon, and night) were conducted for 6 months. RESULTS: A total of 336 patients were included in the study, obtaining an overall crude prevalence of PR use of 16 % (95 %CI: 15 %-17.7 %). Pediatric patients with respiratory pathology received the highest number of hours of PR, with significant differences observed when comparing respiratory cases with post-surgical cases. Statistical significance was also observed when comparing the mean scores of hours of PR according to admission diagnosis (p = 0.01), with respiratory patients being the ones who were restrained the longest (24 h [20-24]) and infectious patients the least (15 h [14-20]). Patients who receive PR upon admission remain in this situation for more hours (24 h [15-24] and in the PICUs that specifically recorded PR application, fewer hours of PR occurred (20 h [4-24]). CONCLUSIONS: The use of PR is still present in the PICUs analyzed, with a crude prevalence of 16%. Factors such as the reason for admission, the use of respiratory support, and the reason for application of PR were linked to the hours of use of PR. IMPLICATIONS FOR CLINICAL PRACTICE: Knowing the prevalence of PR use will make professionals aware that it is still necessary to implement policies that avoid its use to prevent the side effects they have in pediatric patients.

Intention to use physical restraint in paediatric intensive care units and correlated variables: A multicentre and cross-sectional study.

OBJECTIVES: To determine the intention to use physical restraint (PR) and the relationship with sociodemographic and professional variables of the Paediatric Intensive Care Unit (PICU) nurses. RESEARCH METHODOLOGY/DESIGN AND SETTING: A multicentre and correlational study was carried out from October 2021 to December 2023 in five paediatric intensive care units from five maternal and child hospitals in Spain. The Paediatric Physical Restraint-Theory of Planned Behaviour Questionnaire was provided. Moreover, sociodemographic and employment variables were registered. RESULTS: A total of 230 paediatric nurses participated in the study. A total of 87.7 % were females with an average age of 35.5 ± 9.7 years and working experience of 10.5 ± 8.4 years. The mean scores obtained were 21.1 ± 3.8 for attitude, 13.1 ± 5.0 for subjective norms, 14.4 ± 4.3 for perceived behavioural control and 28.0 ± 6.0 for intention. The nurses apply more physical restraint to anxious patients, with scarce analgesics and sedation, those affected with pharmacological withdrawal symptoms and those with a high risk of accidental removal of vital support devices or fall from bed. The sex (p = 0.007) and type of employment contract (p = 0.01) are the variables that are significantly correlated with the intention to use of PR. CONCLUSION: The paediatric nurses analysed had a moderate attitude, social pressure and perceived behavioural control towards the use of PR. IMPLICATIONS FOR CLINICAL PRACTICE: It is important to know the factors that influence the intention to use physical restraint in order to standardise safe practice for critically ill paediatric and to ensure that patients' rights are respected by obtaining informed consent and assessing the prescription, continuation and removal of physical restraint.

A novel NKp80-based strategy for universal identification of normal, reactive and tumor/clonal natural killer-cells in blood.

Purpose: Natural killer (NK) cells are traditionally identified by flow cytometry using a combination of markers (CD16/CD56/CD3), because a specific NK-cell marker is still missing. Here we investigated the utility of CD314, CD335 and NKp80, compared to CD16/CD56/CD3, for more robust identification of NK-cells in human blood, for diagnostic purposes. Methods: A total of 156 peripheral blood (PB) samples collected from healthy donors (HD) and patients with diseases frequently associated with loss/downregulation of classical NK-cell markers were immunophenotyped following EuroFlow protocols, aimed at comparing the staining profile of total blood NK-cells for CD314, CD335 and NKp80, and the performance of distinct marker combinations for their accurate identification. Results: NKp80 showed a superior performance (vs. CD314 and CD335) for the identification of NK-cells in HD blood. Besides, NKp80 improved the conventional CD16/CD56/CD3-based strategy to identify PB NK-cells in HD and reactive processes, particularly when combined with CD16 for further accurate NK-cell-subsetting. Although NKp80+CD16 improved the identification of clonal/tumor NK-cells, particularly among CD56- cases (53%), aberrant downregulation of NKp80 was observed in 25% of patients, in whom CD56 was useful as a complementary NK-cell marker. As NKp80 is also expressed on T-cells, we noted increased numbers of NKp80+ cytotoxic T-cells at the more advanced maturation stages, mostly in adults. Conclusion: Here we propose a new robust approach for the identification of PB NK-cells, based on the combination of NKp80 plus CD16. However, in chronic lymphoproliferative disorders of NK-cells, addition of CD56 is recommended to identify clonal NK-cells, due to their frequent aberrant NKp80- phenotype.

Detection of Thelazia callipaeda in Phortica variegata and spread of canine thelaziosis to new areas in Spain.

BACKGROUND: The fruit fly Phortica variegata (Drosophilidae: Steganinae) feeds on the ocular secretions of animals and humans, and has been described as an intermediate host of the eye worm Thelazia callipaeda (Spirurida: Thelaziidae) in Italy. Despite the increased detection of T. callipaeda in many European countries, information about its vector role in natural conditions is still limited. In the Iberian Peninsula, thelaziosis caused by T. callipaeda has been reported in dogs, cats, red foxes, wild rabbits and humans. METHODS: In the last seven years, we have detected increased numbers of cases of canine thelaziosis at three locations in mainland Spain: Site 1, La Vera region (Cáceres Province, central-western Spain; 51 cases); Site 2, El Escorial municipality (Madrid Community, central Spain; 23 cases); and Site 3, Miraflores de la Sierra municipality (Madrid Community, central Spain; 41 cases). Site 1 is considered endemic for T. callipaeda while the other two sites have been recently recognised as risk zones for T. callipaeda infection. RESULTS: From June 2016 to September 2017, 2162 flies were collected and morphologically identified as Phortica spp. (Site 1, n = 395; Site 2, n = 1544; and Site 3, n = 223). Upon dissection, third-stage T. callipaeda larvae were found in two out of 155 flies examined from Site 1, and both these larvae tested molecularly positive for the eye worm. Of the 395 flies collected from Site 1, 371 were molecularly processed for arthropod species identification and T. callipaeda detection. All 371 flies were identified as P. variegata and 28 (7.5%; 95% CI: 4.8-10%) tested positive for T. callipaeda DNA haplotype 1. CONCLUSIONS: Our findings indicate that T. callipaeda circulates among dogs and P. variegata in Spain, where zoonotic cases have been also reported. The co-existence of canine thelaziosis and Phortica spp. in geographical areas previously considered free of the eye worm indicates a risk of infection for both animals and humans living in this region.

Diagnóstico por imagen en infección urinaria: revisión de un año / Diagnostic by image in urinary infetion: review of 1 year

La infección urinaria (ITU) en niños adquiere importancia debido a: dificultad diagnóstica, alta tasa de recidivas, asociación con malformaciones urinarias y posibilidad de producir lesiones renales. Los niños portadores de ITU deben estudiarse para pesquisar alteraciones urinarias anatómicas o funcionales. Revisamos antecedentes clínicos y resultados de exámenes de imágenes (ecografía, uretrocistografía, pielografía de eliminación) de 323 pacientes enviados a la Unidad de Radiología del Hospital Roberto del Río durante un año con diagnósticos de ITU o pielonefritis aguda. En 191 pacientes el estudio fue considerado completo y en 45 niños (23,6%) resultó patológico. La alteración más frecuente fue el reflujo vesicoureteral. También se pesquisaron alteraciones inflamatorias transitorias, dobles sistemas de eliminación, nefropatías de reflujo, divertículos vesicales, hidronefrosis no obstructivas y otras alteraciones menos frecuentes. Consideramos que el número y variedad de alteraciones pesquisadas, justifican el estudio de imágenes en estos pacientes
