Anconeus and pronation: a palpatory and ultrasonographic study.

PURPOSE: Depending on its axis, pronation varies from the radius rotation around the steady ulna to the reciprocal adduction of the radius and abduction of the ulna. While there is no question that pronator teres is a central pronation agonist, anconeus's role is not settled. The current investigation comparing palpation and ultrasonography in these two muscles during pronation along the axis capitulum-second digit evolved from a serendipitous finding in a clinical anatomy seminar. METHODS: Single-hand palpation and two-transducer ultrasonography over anconeus and pronator teres were used on ten normal subjects to investigate their contraction during pronation around the capitulum-second digit axis. These studies were done independently and blind to the results of the other. The statistical analysis between palpation and ultrasonography was performed with Cohen's kappa coefficient and the χ2 test. RESULTS: On palpation, on resisted full pronation, anconeus contracted in 8/10 subjects and pronator teres in 10/10 subjects. Without resistance, the corresponding ratios were 5/10 and 9/10. On two-transducer ultrasonography, the comparable ratios were 7/10 and 10/10, and 3/10 and 10/10. A fair concordance (Cohen's kappa = 0.21) between palpation and ultrasonography in detecting the simultaneous status of anconeus and pronator teres during resisted full pronation. Anatomic dissection illustrated the elements involved. CONCLUSIONS: Plain palpation confirmed by ultrasonography showed the simultaneous contraction of anconeus and pronator teres during resisted pronation in most of the studied subjects. The study suggests that palpation can be helpful in directly studying muscle activity during movement.

Relationship of Hematological Profiles with the Serum Complement System in Patients with Systemic Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder identified by hematological abnormalities including anemia, leukopenia, and thrombocytopenia. Complement system disturbance is implicated in the pathogenesis of SLE. In this work, we aim to study how a full assessment of the complement system, which includes the evaluation of its three pathways, relates to blood cell counts in a population of patients with SLE. New-generation functional assays of the classical, alternative, and lectin pathways of the complement system were conducted in 284 patients with SLE. Additionally, serum levels of inactive molecules (C1q, C2, C3, C4, factor D) and activated molecules (C3a), as well as regulators (C1-inhibitor and factor H), were evaluated. Complete blood cell counts were analyzed. Multivariable linear regression analysis was performed to study the relationship of hematological profiles with this full characterization of the complement system. After multivariable adjustments that included age, sex, SLICC-DI (damage), and SLEDAI (activity) scores, as well as the use of aspirin, prednisone, methotrexate, azathioprine, and mycophenolate mofetil, several relationships were observed between the C pathways and the individual products and blood cells profile. Lower values of C1q and C2 were associated with lower hemoglobin levels. Lower leukocyte counts showed significantly lower values of C4, C1 inhibitor, C3, factor D, and alternative pathway functional levels. Neutrophil counts showed significant negative relationships only with the alternative pathway and C1-inh. In the case of lymphocytes, associations were found, especially with functional tests of the classical and alternative pathways, as well as with C2, C4, C3, and C3a. On the contrary, for platelets, significance was only observed, after multivariable adjustment, with lower C2 concentrations. In conclusion, the serum complement system and hematological profile in SLE are independently linked, after adjustment for disease activity and damage. These relationships are basically negative and are predominantly found in lymphocytes.

Red blood cell distribution width as a surrogate biomarker of damage and disease activity in patients with systemic lupus erythematosus.

OBJECTIVES: Red blood cell distribution width (RDW) is a measure of variability in mean corpuscular volume. Alterations in RDW can be observed in a variety of human disorders, including inflammatory, cardiovascular, and hepatic or renal diseases. Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect virtually any organ in the body. In this work, our objective was to analyse how a complete characterisation of disease characteristics in a large series of patients with SLE is related to RDW values. METHODS: 284 patients with SLE and 181 age- and sex-matched healthy controls were recruited. Complete blood count including RDW was assessed. Multivariable analysis was performed to analyse the relationship between RDW and SLE disease characteristics, including composite scores of disease activity and damage. RESULTS: After multivariable adjustment, RDW was higher in patients with SLE compared to controls (beta coefficient 0.8 [95% confidence interval: 0.3-1] %, p=0.003). Several disease characteristics, such as the presence of extractable nuclear antibodies and antiphospholipid syndrome, and the use of prednisone and azathioprine, were significantly associated with higher levels of RDW after adjustment for confounders. Of note, cumulative disease damage and disease activity scores were associated with higher RDW values after controlling for covariates. CONCLUSIONS: RDW may serve as a surrogate biomarker of accrual disease damage and activity in patients with SLE.

Mean Platelet Volume Is Related to Cumulative Disease Damage in Patients with Systemic Lupus Erythematosus.

Mean platelet volume (MPV), which represents the average platelet size in femtoliters, has emerged as a reliable biomarker in several systemic and chronic disorders. However, its relationship with disease characteristics in large series of patients with systemic lupus erythematosus (SLE) has not been exhaustively studied to date. In the present work, we aimed to analyze how disease characteristics, including disease activity and cumulative damage, relate to MPV in a well-characterized series of SLE patients. In total, 179 patients with SLE and 181 age- and sex-matched healthy controls were recruited. Complete blood counts including MPV were assessed. Linear multivariable analysis was performed to evaluate the relationship between MPV and SLE disease characteristics, including composite scores of disease activity and damage. MPV was significantly lower in patients with SLE compared to controls after multivariable analysis (beta coefficient, -0.7 [95% confidence interval, -1.1 to -0.3)] fL, p < 0.001). Although the SLEDAI disease activity index was not related to MPV, the SLICC score measuring cumulative disease damage was significantly associated with lower MPV values after adjustment for covariates. Elements of the SLICC score that were associated with lower MPV levels were those pertaining to the kidney, peripheral vascular, and musculoskeletal manifestations of the disease. In conclusion, MPV is lower in patients with SLE compared to matched controls. This MPV downregulation is primarily due to the renal, peripheral vascular and musculoskeletal manifestations of the disease. MPV may represent a biomarker of accrual disease damage in SLE.

Patient safety in surgical settings: A study on the challenges and improvement strategies in adverse event reporting from a nursing perspective.

AIMS: To explore adverse event reporting in the surgical department through the nurses' experiences and perspectives. DESIGN: An exploratory, descriptive qualitative study was conducted with a theoretical-methodological orientation of phenomenology. METHODS: In-depth interviews were conducted with 15 nurses, followed by an inductive thematic analysis.

The research underscores the importance of an open, supportive culture in healthcare, which is vital for transparent communication and effective reporting, ultimately advancing patient safety. REPORTING METHOD: The study followed the Standards for Reporting Qualitative Research and the Consolidated Criteria for Reporting Qualitative Research guidelines. PATIENTS OR PUBLIC CONTRIBUTION: No patients or public contribution.

Examining the Forearm Intersection through Palpation and Ultrasonography.

BACKGROUND: Forearm intersection syndrome causes pain, swelling, and a rub at the dorsal distal forearm where the first extensor compartment muscles intersect with the second compartment tendons. Although primary care settings tend to treat mild cases, high-performance athletes may suffer from severe symptoms that require surgery. This proof-of-concept study aims to help detect the anatomical substrate of forearm intersection syndrome using palpation and ultrasonography when available. METHODS: Five individuals were studied using independent palpation and ultrasonography to identify the first dorsal compartment muscles and the second dorsal compartment tendons. The distances between the dorsal (Lister's) tubercle of the radius and the ulnar and radial edges of the first dorsal compartment muscles were measured to determine the location and extent of the muscle-tendon intersection. The palpatory and ultrasonographic measurements were compared using descriptive statistics and the paired t-test. RESULTS: The mean distances from the dorsal tubercle of the radius to the ulnar and radial borders of the first dorsal compartment muscles were 4.0 cm (SE 0.42) and 7.7 cm (SE 0.56), respectively, based on palpation. By ultrasonography, the corresponding distances were 3.5 cm (SD 1.05, SE 0.47) and 7.0 cm (SD 1.41, SE 0.63). Both methods showed a similar overlap length. However, ultrasonography revealed a shorter distance between the dorsal tubercle of the radius and the ulnar border of the first compartment than palpation (p = 0.0249). CONCLUSIONS: Our findings indicate that a basic knowledge of anatomy should help health professionals diagnose forearm intersection syndrome through palpation and, if available, ultrasonography.

Hematological Composite Scores in Patients with Inflammatory Bowel Disease.

The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and the systemic immune-inflammatory index (SIRI, neutrophils × monocytes/lymphocytes) have been identified as potential inflammatory biomarkers. In this work we aimed to analyze whether the hematological composite scores differ between inflammatory bowel disease (IBD) patients and healthy controls, and if they are related to disease activity. A total of 197 IBD patients-130 Crohn's (CD) disease and 67 ulcerative colitis (UC)-and 208 age- and sex-matched healthy controls were enrolled. C-reactive protein and fecal calprotectin were assessed. Multivariable linear regression analysis was executed. After adjustment, NLR and PLR, but not SIRI and MLR, were significantly higher in IBD patients compared to controls. C-reactive protein and SIRI and NLR were correlated in IBD patients. However, fecal calprotectin was not related to any of these blood scores. Furthermore, disease activity parameters were not associated with any of the blood composite scores in both CD and UC patients. In conclusion, NLR and PLR, but not SIRI and MLR, are independently higher in IBD patients compared to controls. However, the four hematological scores are not related to disease activity in either CD or UC patients. Based on these results, blood-based inflammatory scores may not serve as subrogated biomarkers of disease activity in IBD.

Perspectiva parental del cuidado humanizado de la Unidad de Cuidados Intensivos Pediátricos / Parental perspective of humanized care at the Paediatric Intensive Care Unit

Objetivo: describir el cuidado humanizado en Enfermería desde la perspectiva parental en la Unidad de Cuidados Intensivos Pediátricos (UCIP).Método: orientación fenomenológica de Husserl. Los participantes han sido progenitores de población infantil de entre 3 a 6 años ingresados en la UCIP en la Comunidad de Madrid. Se ha realizado un muestreo por conveniencia y bola de nieve con nueve participantes. La recopilación de datos ha sido mediante entrevistas semiestructuradas a partir de preguntas abiertas sobre temas de interés con una duración entre 40 y 50 minutos. El análisis de contenido se realizó siguiendo el método de Strauss y Corbin en tres fases.Resultados: se identificaron tres categorías: Disrupción del ingreso en la UCIP, Tiempo y espacio en la UCI Pediátricos y Atención enfermera en la UCIP. Los progenitores manifestaron un gran desconocimiento acerca de los cuidados y las labores realizadas en las unidades de cuidados intensivos antes del ingreso de sus hijos e hijas. En todos los casos sintieron miedo e incertidumbre. Los progenitores valoraron la constancia, el seguimiento exhaustivo y el apoyo emocional como una parte fundamental de los cuidados del personal de Enfermería en estas unidades.Conclusiones: todavía existe un desafío en la inclusión efectiva de los padres y hay una percepción insuficiente del apoyo del equipo de Enfermería hacia ellos y ellas. Se debe considerar incluir a las familias en los cuidados de sus hijos e hijas en una UCIP para disminuir el estrés y mejorar la percepción de la atención enfermera. (AU)

Objective: to describe the humanized Nursing care from the parental perspective at the Paediatric Intensive Care Unit (PICU).Method: husserlian-oriented descriptive phenomenological methodology. The participants were parents of the paediatric population (3-to-6 years old) admitted at the PICU in the Community of Madrid. Convenience and snowball sampling were conducted with nine participants. There was data collection through semistructured interviews based on open questions about topics of interest, with a duration between 40 and 50 minutes. Content analysis was conducted following the method in three stages by Strauss and Corbin.Results: three categories were identified: Disruption of admission at the PICU, Time and space at the Pediatric ICU, and Nursing care at the PICU. Parents showed a major lack of knowledge about the care and tasks conducted at the Intensive Care Units before their children were admitted. In all cases, they felt fear and uncertainty. Parents valued consistency, thorough follow-up and emotional support as an essential part of Nursing care in these units.Conclusions: the effective inclusion of parents still represents a challenge, and there is an insufficient perception of the support by the Nursing team towards them. It must be considered to include families in the care of their children at the PICU, in order to reduce stress and improve the perception of Nursing care. (AU)

Help! Caring for People With Mental Health Problems in the Emergency Department: A Qualitative Study.

INTRODUCTION: After coronavirus disease 2019, there has been an increase in patients in the emergency department with mental health conditions. They are usually received by professionals who are not specialized in mental health. This study aimed to describe nursing staff's experiences in the emergency department, in the care they provide to people with mental health problems who often feel stigmatized by society and also in health care settings. METHODS: This is a descriptive qualitative study with a phenomenological approach. The participants were nurses from the Spanish Health Service from the emergency department of the Community of Madrid hospitals. Recruitment was performed by convenience sampling snowball sampling until data satruation was met. Data were collected through semistructured interviews conducted during January and February 2022. RESULTS: The exhaustive and detailed analysis of the nurses' interviews made it possible to extract 3 main categories-health care, psychiatric patient, and work environment-with 10 subcategories. DISCUSSION: The main study findings were the need to train emergency nurses to be prepared to care for people who experience mental health concerns including bias education and the need for implementation of standardized protocols. Emergency nurses never doubted their ability to care for people experiencing mental health disorders. Still, they recognized that they needed specialized professionals' support at certain critical moments.

Phantoms for ultrasound-guided vascular access cannulation training: a narrative review.

The objective of this paper is to review and compare the different commercial and homemade models of ultrasound-guided vascular cannulation phantoms, as well as the methods used for the elaboration of the latter. There are a variety of simulators for ultrasound-guided puncture techniques, from simple homemade phantoms to the most sophisticated and expensive virtual reality simulators. Commercial-grade ultrasound phantoms are expensive and although they are reusable, their cost can be a barrier to simulation-based training. Homemade phantoms are a cost-effective, highly useful tool for teaching vascular access using ultrasound. For the elaboration of the homemade ones, different substances and elements are usually used to produce varied echogenicities and geometries. Specifically, animal-based ones provide more realistic tissue feedback and have a back-ground echogenicity that is closer to that of human tissue. A powerful alternative is the use of poly vinyl alcohol or modified mixtures of this material, which would be better suited to cannulation simulation with high functional fidelity.

Back to Clinical Training during the COVID-19 Pandemic: Perspective of Nursing Students.

INTRODUCTION: The COVID-19 pandemic has affected many areas of life, including the formation of nursing students. After the COVID-19 crisis, learning during clinical training created different challenges. Nursing schools are responsible for ensuring that structures are in place to facilitate coping in the changed clinical setting. This study aimed to analyze nursing students' perceptions during clinical training while caring for COVID-19 patients. MATERIAL AND METHODS: A qualitative phenomenological study that explored nursing students' perceptions of learning in clinical settings with COVID-19 patients was performed. A total of 15 semi-structured face-to-face interviews were conducted with nursing students who carried out their clinical practices in COVID-19 units during February and April 2022. RESULTS: Through content analysis, categorization, and the method of comparison constant, four categories emerged: feelings, challenges, coping methods, and clinical practices. The students had to learn to "work" with fear and uncertainty and self-manage the emotional burden using different coping techniques to deal with learning during their practices. Interacting with professors and clinical tutors during the clinical practice were positive experiences. CONCLUSIONS: This study constituted an opportunity to build new and adapted educational approaches for teachers to train nursing students to deal with their emotions and thoughts in future pandemic situations.

Challenge, fear and pride: nursing students working as nurses in COVID-19 care units.

CONTEXT AND PURPOSE: During the crisis caused by the COVID-19 pandemic in Spain, students in the year of undergraduate degree were hired to provide care assistance support in hospitals. The purpose of the study is to explore their experiences of their premature professional incorporation into patient care in a pandemic situation. METHODS: A descriptive phenomenology research study was conducted. Data were collected in two phases: 1) Two focus groups and 2) Ten in-depth individual semi-structured interviews between July and August 2021. RESULTS: Twenty-two Nursing students from a Madrid University School of Nursing participated. All worked in COVID hospitalization units, 6 in intensive care units. Four main categories were identified. Student-professional nurse transition, Learning, Hospital integration and Emotions. CONCLUSION: Despite all the fears and negative emotions, the nursing students do not regret the decision to accept a contract to work as a healthcare professional in the COVID-19 pandemic. They feel that the pandemic has allowed them to see life from another perspective and with other priorities, strengthening their vocation to nursing.
