Checklist: Neck computed tomography in non-traumatic emergencies.

Patients attending the emergency department (ED) with cervical inflammatory/infectious symptoms or presenting masses that may involve the aerodigestive tract or vascular structures require a contrast-enhanced computed tomography (CT) scan of the neck. Its radiological interpretation is hampered by the anatomical complexity and pathophysiological interrelationship between the different component systems in a relatively small area. Recent studies propose a systematic evaluation of the cervical structures, using a 7-item checklist, to correctly identify the pathology and detect incidental findings that may interfere with patient management. As a conclusion, the aim of this paper is to review CT findings in non-traumatic pathology of the neck in the ED, highlighting the importance of a systematic approach in its interpretation and synthesis of a structured, complete, and concise radiological report.

Lista de verificación: tomografía computarizada de cuello en urgencias no traumáticas / Checklist: Neck computed tomography in non-traumatic emergencies

A los pacientes que acuden a urgencias con síntomas inflamatorio/infecciosos a nivel cervical o con masas que pueden comprometer el tracto aerodigestivo o las estructuras vasculares, es necesario hacerles una tomografía computarizada (TC) de cuello con contraste. Su interpretación radiológica se ve dificultada por la complejidad anatómica y la interrelación fisiopatológica entre los diferentes sistemas que lo componen, en un área de estudio relativamente pequeña. Estudios recientes proponen realizar una evaluación sistemática de las estructuras cervicales, utilizando para ello un listado de verificación de 7 elementos, para identificar correctamente la patología, y detectar los hallazgos incidentales que pueden interferir en el manejo del paciente. El objetivo de este trabajo es revisar los hallazgos de la TC en la patología no traumática del cuello en urgencias siguiendo una lectura sistemática, tras la cual se pueda realizar un informe radiológico estructurado, completo y conciso.(AU)

[Comparison of quality of life in patients living with HIV infection through pharmaceutical care according to CMO methodology vs. conventional follow-up. MAS-VIH project]. / Comparación de la calidad de vida en personas que viven con infección por VIH en seguimiento mediante atención farmacéutica según metodología capacidad motivación-oportunidad vs. seguimiento convencional. Proyecto MAS-VIH.

OBJECTIVE: To compare quality of life, in patients living with HIV infection with pharmaceutical care according to the CMO methodology: capacity, motivation and opportunity versus conventional follow-up. METHODS: Longitudinal, prospective, multicenter, health intervention study, conducted between October 2019 and November 2021 in 14 centers throughout Spain. Patients over 18 years of age, receiving antiretroviral treatment and attending the consultations of the participating Pharmacy Services for 1 year were included. Patients who did not have the autonomy to complete the planned questionnaires were excluded. At baseline, participating centers were randomized to continue using the same systematics of work (traditional follow-up) or to implement the CMO model using patient stratification models, goal setting in relation to pharmacotherapy, use of motivational interviewing, as well as longitudinal follow-up enabled by new technologies. The main variable was the difference in the number of dimensions positively affected in each follow-up arm at 24 weeks of follow-up according to the MOS-HIV questionnaire. In the CMO group, the interventions performed the most frequently were recorded. RESULTS: 151 patients were included. The median age was 51.35 years. A significant improvement in quality of life was found at the end of follow-up in the CMO group, reducing the number of patients with negatively affected dimensions (2/11 vs 8/11). The most frequent interventions carried out in the CMO group, according to the taxonomy, were Motivation (51,7%) and review and validation (49,4%). CONCLUSIONS: The quality of life of patients is higher in those centers that develop Pharmaceutical Care based on the CMO methodology compared to traditional follow-up.

Dietary antioxidant intake reduces carotid intima-media thickness in coronary heart disease patients: From the CORDIOPREV study.

BACKGROUND: Atherosclerosis is the leading underlying cause of coronary heart disease (CHD). In patients with CHD, intima-media thickness of common carotid arteries (IMT-CC) is a reliable, validated, and non-invasive marker of the progression of atherosclerosis. Dietary intervention may affect IMT-CC evolution through different pathways. There is a lack of clinical trials evaluating the effect of total dietary antioxidant content of diets on IMT-CC, especially in patients with CHD. OBJECTIVE: We evaluated the correlation between the diet's total antioxidant content and the changes in IMT-CC produced after 5 years of dietary intervention following two healthy diet models (Mediterranean diet and low-fat diet). We also evaluated whether the diet's total antioxidant content was related to the total redox capacity of the participants. METHODS: From the total participants of the CORDIOPREV study (clinical trial register NCT00924937), 805 participants completed the IMT-CC measurement and the dietary antioxidant evaluation at baseline and after 5 years of dietary intervention. IMT-CC was carried out by ultrasound and the dietary antioxidant evaluation was performed by the Dietary Antioxidant Index (DAI). Additionally, direct redox balance was evaluated in a subset of population by the ratio of reduced glutathione (GSH) to oxidized glutathione (GSSH) by colorimetric assay. RESULTS: We observed an inverse correlation between evolution of DAI and IMT-CC after 5-years of dietary intervention. The mean of the DAI index augmented in the Mediterranean Diet group, whereas it decreased in the Low-fat group. DAI was correlated to the GSH/GSSG ratio, supporting DAI as an adequate estimator of diet's antioxidant content. When looking for individual components of the DAI that were associated to the changes in IMT-CC, an inverse correlation was found for carotenoids, vitamin E, vitamin C, and zinc and the IMT-CC. CONCLUSIONS: Our study indicates that, after five years of dietary intervention, changes in DAI inversely correlate with changes in IMT-CC in patients with CHD. Overall effect of Mediterranean diet resulted in an increase of DAI, conversely to low-fat. Specific elements included in the DAI index were inversely correlated with IMT-CC.

Do preschoolers trust a competent robot pointer?

How young children learn from different informants has been widely studied. However, most studies investigate how children learn verbally conveyed information. Furthermore, most studies investigate how children learn from humans. This study sought to investigate how 3-year-old children learn from, and come to trust, a competent robot versus an incompetent human when competency is established using a pointing paradigm. During an induction phase, a robot informant pointed at a toy inside a transparent box, whereas a human pointed at an empty box. During the test phase, both agents pointed at opaque boxes. We found that young children asked the robot for help to locate a hidden toy more than the human (ask questions) and correctly identified the robot to be accurate (judgment questions). However, children equally endorsed the locations pointed at by both the robot and the human (endorse questions). This suggests that 3-year-olds are sensitive to the epistemic characteristics of the informant even when its displayed social properties are minimal.

High-risk Opioid Prescribing Associated with Postoperative New Persistent Opioid Use in Adolescents and Young Adults.

OBJECTIVE: In this study, we explored which postoperative opioid prescribing practices were associated with persistent opioid use among adolescents and young adults. BACKGROUND: Approximately 5% of adolescents and young adults develop postoperative new persistent opioid use. The impact of physician prescribing practices on persistent use among young patients is unknown. METHODS: We identified opioid-naïve patients aged 13 to 21 who underwent 1 of 13 procedures (2008-2016) and filled a perioperative opioid prescription using commercial insurance claims (Optum Deidentified Clinformatics Data Mart Database). Persistent use was defined as ≥ 1 opioid prescription fill 91 to 180 days after surgery. High-risk opioid prescribing included overlapping opioid prescriptions, co-prescribed benzodiazepines, high daily prescribed dosage, long-acting formulations, and multiple prescribers. Logistic regression modeled persistent use as a function of exposure to high-risk prescribing, adjusted for patient demographics, procedure, and comorbidities. RESULTS: High-risk opioid prescribing practices increased from 34.9% to 43.5% over the study period; the largest increase was in co-prescribed benzodiazepines (24.1%-33.4%). High-risk opioid prescribing was associated with persistent use (aOR 1.235 [1.12,1.36]). Receipt of prescriptions from multiple opioid prescribers was individually associated with persistent use (aOR 1.288 [1.16,1.44]). The majority of opioid prescriptions to patients with persistent use beyond the postoperative period were from nonsurgical prescribers (79.6%). CONCLUSIONS: High-risk opioid prescribing practices, particularly receiving prescriptions from multiple prescribers across specialties, were associated with a significant increase in adolescent and young adult patients' risk of persistent opioid use. Prescription drug monitoring programs may help identify young patients at risk of persistent opioid use.

Precision and Safety of Ultrasound-Guided versus Palpation-Guided Needle Placement on the Patellar Tendon: A Cadaveric Study.

For decades, needling interventions have been performed based on manual palpation and anatomic knowledge. The increasing use of real-time ultrasonography in clinical practice has improved the accuracy and safety of needling techniques. Although currently ultrasound-guided procedures are routinely used for patellar tendon pathology, e.g., during percutaneous electrolysis, the accuracy of these procedures is still unknown. This study used a cadaveric model to compare and evaluate both the accuracy and safety of ultrasound-guided and palpation-guided needling techniques for the patellar tendon. A total of five physical therapists performed a series of 20 needle insertion task each (n = 100), 10 insertions based on manual palpation (n = 50) and 10 insertions guided with ultrasound (n = 50) to place a needle along the interface between the patellar tendon and Hoffa's fat pad. All procedures were performed on cryopreserved knee specimens. Distance to the targeted tissue, time of the procedure, accurate rate of insertions, number of passes, and unintentional punctured structures between both applications (with and without ultrasound guiding) were compared. The results revealed higher accuracy (100% vs. 80%), a lower distance from needle to the targeted tissue (0.25 ± 0.65 vs. 2.5 ± 1.9 mm), longer surface of contact with the needle (15.5 ± 6.65 vs. 4.7 ± 7.5 mm), and a lower frequency of patellar tendon puncture (16% vs. 52%, p < 0.001) with the ultrasound-guided procedure as opposed to palpation-guided one. Nevertheless, the ultrasound-guided procedure took longer (54.8 ± 26.8 vs. 23.75 ± 15.4 s) and required more passes (2.55 ± 1.9 vs. 1.5 ± 0.95) to be conducted than the palpation-guided procedure (all, p < 0.001). According to these findings, the accuracy of invasive procedures applied on the patellar tendon is higher when conducted with ultrasound guidance than when conducted just on manual palpation or anatomical landmark. These results suggest that ultrasound could improve the clinical application of invasive procedures at the fat-patellar tendon interface. Due to the anatomical features of the targeted tissue, some procedures require this precision, so the use of ultrasound is recommended.

The Road to Mastery: An Analysis of Goal Orientation in the Transition from Medical School to Surgical Residency.

PURPOSE: Goal orientation (GO) is a psychological construct which describes an individual's intrinsic motivation for learning in terms of mastery and performance goals. Mastery goals relate to the intrinsic drive to learn for the sake of learning, while performance goals are oriented toward validating one's own competence by seeking favorable judgments (Performance Approach; PAP) or avoiding negative judgments (Performance Avoid; PAV). Having a mastery GO has been shown to improve overall job satisfaction as well as optimize job performance. We therefore aimed to examine how GO changes during the transition to residency, which is a notoriously challenging period in medical education, and identify interventions that can increase mastery of GO. METHODS: The validated Goal Orientation in Surgical Trainees (GO-ST) instrument was administered to incoming surgical interns (n = 19) during orientation in a single, university-based program and again at 3 months into the internship. The perceived stress scale (PSS) was also administered at 3 months. Focus groups were used to assess resident perceptions and identify interventions at the end of the 3-month period. RESULTS: Eighteen interns (95%) completed a baseline GO-ST assessment and the 3-month follow-up, including the PSS. Mastery GO decreased from orientation to 3-month follow-up for the entire cohort, but this was not significant (3.89-3.63; p = 0.19). Preliminary interns showed a significant increase in PAV orientation after 3 months (3.28-3.67; p = 0.04) and had significantly lower mastery orientation scores at this time (4.07 vs 3.19; p = 0.02). PSS was significantly higher in preliminary interns at 3 months (18.56 vs 11.89; p = 0.04). Those who were predominantly mastery oriented had significantly lower perceived stress scores (11.64 vs 20.10; p = 0.002) compared with those that had performance goal orientations (PAP and PAV). Five interns (28%) participated in focus groups-identifying pertinent themes: 1) Perceptions of competence, 2) Training security; 3) Feedback approach, 4) Expectations of competence, and 5) Approaches to growth. CONCLUSION: Mastery GO declines during the transition to surgical residency. Maladaptive PAV orientation increases in preliminary interns due to different short-term priorities and assumptions of competence. Expectations and perceptions of intern competence by senior residents and attendings have a large impact on intern GO. Identifying interventions that optimize mastery goal orientation and minimize performance avoid orientation will potentially minimize intern stress, thereby improving both well-being and clinical performance.

Controversias en el tratamiento de los miomas / Controversy in the treatment of uterine fibroids

El mioma uterino representa el tumor más frecuente en la mujer de edad reproductiva, aunque solo un 25% de mujeres precisarán tratamiento debido a la presencia de síntomas. Disponemos de pocos estudios aleatorizados que hayan comparado las distintas opciones de tratamiento para el mioma uterino entre ellas; por ahora, la cirugía sigue siendo la opción que ha ofrecido mejores tasas de resolución sintomática, mejoría en calidad de vida y menor tasa de recurrencia. A pesar de la amplia difusión de la cirugía, sí que parece razonable pensar que, disminuyendo los tratamientos quirúrgicos, ya sea con terapias menos invasivas o con nuevos tratamientos médicos, se podría disminuir por un lado la morbilidad asociada a la cirugía y, por otro lado, los costes asociados. En este sentido, las técnicas ablativas para el tratamiento del mioma, la EAU, el HIFU y la radiofrecuencia, han demostrado resultados en cuanto a control sintomático y calidad de vida equiparables a la cirugía, con una baja tasa de complicaciones graves. El mayor problema sería las tasas de recurrencia y el impacto que pueden tener sobre la fertilidad futura de las pacientes. Será necesario disponer de mayor evidencia y estudios comparativos a largo plazo respecto a nuevas técnicas ablativas alternativas a los abordajes quirúrgicos.(AU)

Uterine fibroids are the most common tumours in women of reproductive age, but only 25% of women will require treatment due to the presence of symptoms. There are few randomised studies that have compared the different treatment options for uterine myoma; for the moment, surgery remains the option that offers the best rates of symptomatic resolution, improved quality of life, and a lower recurrence rate. Despite the widespread use of myoma surgery, it seems reasonable to believe that by reducing surgical treatments, either with less invasive therapies or with new medical treatments, both associated morbidity and costs would be reduced. In this sense, ablative techniques for myoma treatment, UAE, HIFU, and radiofrequency, have demonstrated results in terms of symptomatic control and quality of life comparable to surgery, with a low rate of major complications. Recurrence rates and the impact on patients’ future fertility would be the main concern. Future long-term comparative studies of ablative techniques and surgical approaches are needed.(AU)

Divergent pathways of liver fat accumulation, oxidation, and secretion in lipodystrophy versus obesity-associated NAFLD.

BACKGROUND AND AIMS: Fatty liver is common in obesity as well as in partial lipodystrophy (PL) syndromes, characterized by deficient adipose tissue. Insulin resistance is key to fatty liver pathogenesis in both entities. We aimed to compare the contributions of insulin resistance and adipose tissue to hepatic steatosis in PL and non-syndromic, obesity-associated non-alcoholic fatty liver disease (NS-NAFLD). METHODS: In a cross-sectional comparison of people with NS-NAFLD (N = 73) and PL (N = 27), liver fat was measured by FibroScan® controlled attenuation parameter (CAP) and insulin resistance by HOMA-IR, Adipo-IR, and NMR-based LP-IR. RESULTS: Insulin resistance was greater in PL versus NS-NAFLD by HOMA-IR (p = 0.005), Adipo-IR (p = 0.01) and LP-IR (p = 0.05) while liver fat was comparable (304 vs. 324 dB/m, p = 0.12). Liver fat correlated with HOMA-IR in both groups, but CAP values were lower by 32 dB/m in PL compared with NS-NAFLD for any given HOMA-IR. In contrast, Adipo-IR and LP-IR correlated with CAP only in the NS-NAFLD group, suggesting different pathways for fat accumulation. Plasma free fatty acids, reflecting substrate input from the adipose tissue, were comparable between groups. However, the levels of ß-hydroxybutyrate, a marker of ß-oxidation, and large triglyceride-rich lipoprotein particles, a marker of VLDL secretion, were both higher in PL (p < 0.001 for both). CONCLUSION: Liver fat content was comparable in subjects with PL-associated NAFLD and NS-NAFLD, despite worse insulin resistance in partial lipodystrophy. Our data demonstrate higher triglyceride oxidation and export in PL, suggesting a compensatory shift of fat from liver storage into the circulation that does not occur in NS-NAFLD.

Cervical spine trauma.

Cervical spine trauma encompasses a wide of injuries, ranging from stable, minor lesions to unstable, complex lesions that can lead to neurologic sequelae or vascular involvement. The Canadian C-Spine Rule and the NEXUS criteria aim to identify individuals with a low risk of cervical spine trauma who can safely forgo imaging tests. In high-risk patients, an imaging test is indicated. In adult patients the imaging test of choice is multidetector computed tomography. Complementary imaging tests such as CT angiography of the supra-aortic vessels and/or magnetic resonance imaging are occasionally necessary. It can be challenging for radiologists to diagnose and classify these lesions, because some of them can be subtle and difficult to detect. This paper aims to describe the most important imaging findings and the most widely used classification systems.

Enuresis: percepción y actitud en la población de nuestro país / Enuresis: Perception and attitude in population of our country

Objetivo Conocer la percepción y la actitud hacia la enuresis por parte de familias y cuidadores con el objetivo de establecer un plan terapéutico racional. Material y métodos Se realizó una encuesta de 25 preguntas a padres y madres mayores de 18años con al menos un hijo de entre 5 y 13años, manteniendo la representatividad nacional en términos de residencia, clase social y edad de los hijos. La recogida de datos se realizó en abril del 2021. Resultados Se obtuvieron datos de 501 encuestas de 626 enviadas, en su mayoría relativos a familias de clase social media de Andalucía, Cataluña y la Comunidad de Madrid. El 47,9% de los encuestados conocían la existencia de la enuresis, aunque únicamente el 23,8% sabían cuál era el término médico. Solo el 16,6% y el 9,6% recordaban que el/la pediatra o el/la enfermero/a, respectivamente, se hubieran referido en algún momento a la misma. Entre los participantes con algún conocimiento, las fuentes de información principales fueron los casos cercanos (36,6%), los medios de comunicación (31,1%) y el pediatra (27,8%). Los padres se preocuparían mucho (35,3%) o bastante (43,1%) ante un caso. Sin embargo, el nivel de conocimiento fue mayor y el grado de preocupación menor entre padres con hijos con enuresis respecto a los que no tenían casos en la familia. Conclusiones Mejorar el conocimiento de los padres sobre la enuresis y cambiar la percepción que tienen de la misma puede resultar de importancia para mejorar su atención y anticipar su resolución (AU)

Objective To know the perception and attitude towards enuresis from families and caregivers with the aim of establishing a rational therapeutic plan. Material and methods A 25-question survey was performed among parents over 18years old with at least a child between 5 and 13years old, maintaining national representativeness in terms of residence, social class and age of the children. Data collection was performed in April 2021. Results Data from 501 out of 626 sent surveys was obtained, mostly from middle-class families from Andalusia, Catalonia and the Community of Madrid. From all the participants, 47.9% knew about the existence of enuresis, although only 23.8% knew which was the medical term. Only 16.6% and 9.6% remembered that the pediatrician or the nurse, respectively, had referred to the condition at any time. Among the respondents with some knowledge about enuresis, their main information source were close cases (36.6%), media outlets (31.1%) and the pediatrician (27.8%). Parents would be very (35.3%) or somewhat (43.1%) worried in the event of an enuresis case. However, the level of knowledge was higher, and the level of concern was lower among parents with a child with enuresis in comparison to those without a case in their family. Conclusion Improving parent knowledge about enuresis and changing their perception towards this condition might be of importance to improve their attention and anticipate its resolution (AU)

Training nursing students in motivational interviewing for alcohol misuse: A mixed method study.

BACKGROUND: Motivational interviewing led by nurses has been demonstrated to be effective in reducing alcohol consumption among university students. However, most of these professionals feel that they lack the competence necessary for motivational interviewing due to a lack of formal training in the nursing curriculum. OBJECTIVES: To design, implement and evaluate a motivational interviewing training course for alcohol misuse in an undergraduate nursing curriculum and to explore students' experiences with this course. DESIGN: A mixed-methods study involving a descriptive comparative quantitative design and qualitative focus group interviews with nursing students. SETTINGS: An elective nursing course in a Spanish university. PARTICIPANTS: A total of 21 fourth-year nursing students. METHODS: The course was developed as a twelve-week, two-hour course. It comprised three modules covering the concepts, tools and skills associated with motivational interviewing for alcohol misuse. Quantitative and qualitative data were collected after the completion of the course to evaluate the training received by students; these data were categorized using Kirkpatrick's model. The quantitative results included students' satisfaction, knowledge, skills and attitudes, which were measured using an ad hoc questionnaire, a multiple-choice exam, and two rater-based assessments (the Peer Proficiency Assessment instrument and an evidence-based checklist). Qualitative focus groups were used to explore students' experiences of the entire programme. RESULTS: Students' satisfaction with the course was rated 9 out of 10, highlighting the usefulness and adequacy of the course content. The quantitative and qualitative results both indicated that all students acquired the knowledge necessary to perform motivational interviewing and significantly improved their motivational interviewing microskills. Only half of the students reached the level of proficiency in two of the three ratios calculated. The three main themes identified pertained to the learning atmosphere, module methodologies, and students' self-perceptions of competence. Finally, the students reported having transferred their learning to clinical practice. CONCLUSION: A course on motivational interviewing for alcohol misuse positively influences nursing students both personally and in terms of their future professional work by improving their knowledge, skills, attitudes and self-perceived competence.

Changes in quantity plant-based protein intake on type 2 diabetes remission in coronary heart disease patients: from the CORDIOPREV study.

PURPOSE: Diabetes remission is a phenomenon described in the context of drastic weight loss due to bariatric surgery or low-calorie diets. Evidence suggests that increasing the intake of plant protein could reduce the risk of type 2 diabetes. We sought for association between changes in plant protein intake in the context of 2 healthy diets without weight loss nor glucose-lowering medication, and diabetes remission in coronary heart disease patients from the CORDIOPREV study. METHODS: Newly diagnosed type 2 diabetes participants without glucose-lowering treatment were randomized to consume a Mediterranean or a low-fat diet. Type 2 diabetes remission was assessed with a median follow-up of 60 months according to the ADA recommendation. Information on patient's dietary intake was collected using food-frequency questionnaires. At first year of intervention, 177 patients were classified according to changes in plant protein consumption into those who increased or decreased its intake, in order to perform an observational analysis on the association between protein intake and diabetes remission. RESULTS: Cox regression showed that patients increasing plant protein intake were more likely to remit from diabetes than those who decreased its intake (HR = 1.71(1.05-2.77)). The remission occurred mainly at first and second year of follow-up with diminished number of patients achieving remission in the third year onwards. The increase in plant protein was associated with lower intake of animal protein, cholesterol, saturated fatty acids, and fat, and with higher intake of whole grains, fibre, carbohydrates, legumes, and tree nuts. CONCLUSION: These results support the need to increase protein intake of vegetal origin as dietary therapy to reverse type 2 diabetes in the context of healthy diets without weight loss.

Microglia refine developing retinal astrocytic and vascular networks through the complement C3/C3aR axis.

Microglia, a resident immune cell of the central nervous system (CNS), play a pivotal role in facilitating neurovascular development through mechanisms that are not fully understood. Previous reports indicate a role for microglia in regulating astrocyte density. This current work resolves the mechanism through which microglia facilitate astrocyte spatial patterning and superficial vascular bed formation in the neuroretina during development. Ablation of microglia increased astrocyte density and altered spatial patterning. Mechanistically, we show that microglia regulate the formation of the spatially organized astrocyte template required for subsequent vascular growth, through the complement C3/C3aR axis during neuroretinal development. Lack of C3 or C3aR hindered the developmental phagocytic removal of astrocyte bodies and resulted in increased astrocyte density. In addition, increased astrocyte density was associated with elevated proangiogenic extracellular matrix gene expression in C3- and C3aR-deficient retinas, resulting in increased vascular density. These data demonstrate that microglia regulate developmental astrocyte and vascular network spatial patterning in the neuroretina via the complement axis.
