RESUMO

Adolescent subcortical structural brain development might underlie psychopathological symptoms, which often emerge in adolescence. At the same time, sex differences exist in psychopathology, which might be mirrored in underlying sex differences in structural development. However, previous studies showed inconsistencies in subcortical trajectories and potential sex differences. Therefore, we aimed to investigate the subcortical structural trajectories and their sex differences across adolescence using for the first time a single cohort design, the same quality control procedure, software, and a general additive mixed modeling approach. We investigated two large European sites from ages 14 to 24 with 503 participants and 1408 total scans from France and Germany as part of the IMAGEN project including four waves of data acquisition. We found significantly larger volumes in males versus females in both sites and across all seven subcortical regions. Sex differences in age-related trajectories were observed across all regions in both sites. Our findings provide further evidence of sex differences in longitudinal adolescent brain development of subcortical regions and thus might eventually support the relationship of underlying brain development and different adolescent psychopathology in boys and girls.

RESUMO

The neurobiological bases of the association between development and psychopathology remain poorly understood. Here, we identify a shared spatial pattern of cortical thickness (CT) in normative development and several psychiatric and neurological disorders. Principal component analysis (PCA) was applied to CT of 68 regions in the Desikan-Killiany atlas derived from three large-scale datasets comprising a total of 41,075 neurotypical participants. PCA produced a spatially broad first principal component (PC1) that was reproducible across datasets. Then PC1 derived from healthy adult participants was compared to the pattern of CT differences associated with psychiatric and neurological disorders comprising a total of 14,886 cases and 20,962 controls from seven ENIGMA disease-related working groups, normative maturation and aging comprising a total of 17,697 scans from the ABCD Study® and the IMAGEN developmental study, and 17,075 participants from the ENIGMA Lifespan working group, as well as gene expression maps from the Allen Human Brain Atlas. Results revealed substantial spatial correspondences between PC1 and widespread lower CT observed in numerous psychiatric disorders. Moreover, the PC1 pattern was also correlated with the spatial pattern of normative maturation and aging. The transcriptional analysis identified a set of genes including KCNA2, KCNS1 and KCNS2 with expression patterns closely related to the spatial pattern of PC1. The gene category enrichment analysis indicated that the transcriptional correlations of PC1 were enriched to multiple gene ontology categories and were specifically over-represented starting at late childhood, coinciding with the onset of significant cortical maturation and emergence of psychopathology during the prepubertal-to-pubertal transition. Collectively, the present study reports a reproducible latent pattern of CT that captures interregional profiles of cortical changes in both normative brain maturation and a spectrum of psychiatric disorders. The pubertal timing of the expression of PC1-related genes implicates disrupted neurodevelopment in the pathogenesis of the spectrum of psychiatric diseases emerging during adolescence.

RESUMO

OBJECTIVE: Motivation to change has been suggested to significantly impact treatment outcomes in eating disorders (EDs). This review will investigate factors associated with motivation to change in EDs with the aim of supporting clinicians to be aware and sensitive to factors that might obstruct recovery and to inform motivation-based interventions. METHOD: Using PRISMA guidelines, this article identified 24 studies through database searches meeting eligibility criteria. Only correlates of motivation were identified, limiting the ability of this review to identify causal relationships. Factors that changed alongside changes in motivation were identified from longitudinal studies. RESULTS: This review identified factors such as individual characteristics, co-morbid psychopathology, lack of treatment autonomy and relationships with others to be associated with motivation to change in individuals with EDs. In addition, motivation to change significantly increased alongside self-esteem and identity re-negotiation when measured longitudinally. DISCUSSION: Motivational interviewing can typically focus on exploring ambivalence to treatment, identifying goals and values, and increasing self-efficacy. However, this review identifies individual and relational factors to be particularly significant and may obstruct recovery from an ED. As such, evidence-based targets have been identified to inform clinicians and motivation-based interventions. PUBLIC SIGNIFICANCE: Knowledge of factors associated with motivation to change in EDs is important to understand those who may have poorer treatment outcomes. Motivation may be improved by supporting individuals' relationship with others and tailoring interventions according to temperament and personality traits. Utilizing an individual's social support as they enter ED treatment may be effective in maximizing motivation to recover.


OBJETIVO: Se ha sugerido que la motivación al cambio impacta significativamente en los resultados del tratamiento en los trastornos de la conducta alimentaria (TCAs). Esta revisión investigará los factores asociados con la motivación al cambio en los TCAs con el objetivo de apoyar a los clínicos para que estén conscientes y sensibles a los factores que podrían obstaculizar la recuperación e informar las intervenciones basadas en la motivación. MÉTODO: Siguiendo las guías PRISMA, este artículo identificó 24 estudios a través de búsquedas en bases de datos que cumplían con los criterios de elegibilidad. Solo se identificaron correlatos de la motivación, lo que limita la capacidad de esta revisión para identificar relaciones causales. Los factores que cambiaron junto con los cambios en la motivación se identificaron a partir de estudios longitudinales. RESULTADOS: Esta revisión identificó factores como características individuales, psicopatología comórbida, falta de autonomía en el tratamiento y relaciones con otros como asociados con la motivación al cambio en individuos con TCAs. Además, la motivación al cambio aumentó significativamente junto con la autoestima y la renegociación de la identidad cuando se midió longitudinalmente. DISCUSIÓN: La entrevista motivacional típicamente puede centrarse en explorar la ambivalencia hacia el tratamiento, identificando metas y valores, y aumentando la autoeficacia. Sin embargo, esta revisión identifica factores individuales y relacionales como particularmente significativos y que pueden obstaculizar la recuperación de un TCA. Como tal, se han identificado objetivos basados en evidencia para informar a los clínicos y a las intervenciones basadas en la motivación.

RESUMO

OBJECTIVE: An extensive number of predictors has been examined across the literature to improve knowledge of relapse in anorexia nervosa (AN). These studies provide various recovery and relapse definitions, follow-up durations and relapse rates. The current study summarizes these values and predictors of relapse in AN in a review and meta-analysis. METHOD: The study was executed according to PRISMA guidelines. Different databases were searched and studies in which participants did not receive an official clinical diagnosis were excluded. A quality analysis was performed using the National Institute of Health's Study Quality Assessment Tool. Random-effects meta-analyses were conducted to summarize data. RESULTS: Definitions of relapse and recovery were diverse. During an average follow-up period of 31 months an average relapse rate of 37% was found. Predictive variables from 28 studies were grouped in six categories: age and sex, symptoms and behaviors, AN subtype and duration, weight or weight change, comorbidity, and personality. The studies were characterized by non-significant and contradictory results. Meta-analyses were performed for the predictors age, AN duration, pre-treatment BMI, post-treatment BMI and depression. These yielded significant effects for post-treatment BMI and depression: higher pre-treatment depression (SMD = .40 CI [.21-.59] and lower post-treatment BMI (SMD = -.35 CI [-.63 to -.07]) increased relapse chances in AN. DISCUSSION: Our results emphasized a lack of sufficiently powered studies, consistent results, and robust findings. Solely post-treatment BMI and pre-treatment depression predicted relapse. Future research should use uniform definitions, larger samples and better designs, to improve our understanding of relapse in AN. PUBLIC SIGNIFICANCE: Knowledge about predictors is important to understand high relapse rates. Our study performed a review and meta-analysis of relapse predictors in AN. Related to the heterogeneity in studies examining predictors, an overview of relapse and recovery definitions, follow-up durations and relapse rates for AN was provided. Significant effects were found for post-treatment BMI and pre-treatment depression. More studies with uniform definitions are needed to improve clinical implications.


OBJETIVO: En la literatura se ha examinado un amplio número de predictores para mejorar el conocimiento de la recaída en la anorexia nerviosa (AN). Estos estudios proporcionan diversas definiciones de recuperación y recaída, duraciones del seguimiento y tasas de recaída. El presente estudio resume estos valores y predictores de recaída en AN en una revisión y metaanálisis. MÉTODO: El estudio se realizó siguiendo las directrices PRISMA. Se realizaron búsquedas en diferentes bases de datos y se excluyeron los estudios en los que los participantes no recibieron un diagnóstico clínico oficial. Se realizó un análisis de calidad mediante la herramienta de evaluación de la calidad de los estudios del Instituto Nacional de Salud. Se realizaron metaanálisis de efectos aleatorios para resumir los datos. RESULTADOS: Las definiciones de recaída y recuperación fueron diversas. Durante un período de seguimiento promedio de 31 meses se encontró una tasa media de recaída del 37%. Las variables predictivas de 28 estudios se agruparon en seis categorías: edad y sexo, síntomas y conductas, subtipo y duración de la AN, peso o cambio de peso, comorbilidad y personalidad. Los estudios se caracterizaron por resultados no significativos y contradictorios. Se realizaron metaanálisis para los predictores edad, duración de la AN, IMC pretratamiento, IMC postratamiento y depresión. Éstos arrojaron efectos significativos para el IMC postratamiento y la depresión: una mayor depresión pretratamiento (DME = −,40; IC: [21 a, 59] y un menor IMC postratamiento (DME = −,35; IC: [−,63 a −,07]) aumentaron las probabilidades de recaída en la AN. DISCUSIÓN: Nuestros resultados enfatizaron la falta de estudios con suficiente potencia, resultados consistentes y hallazgos robustos. Sólo el IMC postratamiento y la depresión pretratamiento predijeron la recaída. Las investigaciones futuras deberían utilizar definiciones uniformes, muestras más grandes y mejores diseños, para mejorar nuestra comprensión de la recaída en la AN.

RESUMO

The American Academy of Dermatology first published a series of guidelines for diagnosing and managing atopic dermatitis in 2014. Twelve clinicians were selected to review, grade, and offer clinical insight on available data regarding the clinical features, symptomology, pathophysiology, education, treatment, and emerging clinical studies on atopic dermatitis (AD). Based on these findings, the AAD released a guideline to streamline information on atopic dermatitis for physicians, recommending using clinical evidence to diagnose and first treating with nonpharmacologic therapies to restore the natural skin barrier. Topical pharmacologic therapies were recommended for improving pruritus and inflammation and newer systemic agents for clinically relevant moderate-to-severe cases. Evidence-based practices were emphasized in comparison to those that lacked therapeutic data. To highlight the emerging evidence and pharmacologic breakthroughs in atopic dermatitis, the AAD produced an updated set of guidelines educating physicians on new agents and their role in treatment. This chapter reviews the AAD guidelines as a tool for managing atopic dermatitis and staying up to date on disease advancements.

RESUMO

Firearm carriage and possession predicts youth firearm violence victimization and perpetration. This study describes self-reported factors associated with firearm access, carriage, and possession among justice-involved youth. We conducted an exploratory, mixed-methods study. Participants were recruited from May 2022 to February 2023 from the Juvenile Justice Collaborative, a diversion program for justice-involved youth. We used online anonymous surveys to investigate exposures related to firearm access, carriage, and possession. We performed semi-structured interviews using the phenomenology framework. We used descriptive statistics to examine firearm exposures by participant demographics. We performed qualitative analyses using an iterative approach with constant comparison to identify key themes. We completed 28 surveys and 5 interviews. Most survey participants identified as male (57%) and Black (61%) with a median age of 18 years. Interview participants described the socialization and cultural normalization of firearms, most prominently among peers. Survey participants reported whether they had ever carried (25%) or possessed (21%) a firearm. Survey and interview participants endorsed protection in the context of increasing violence exposure over time as the primary motivation for firearm possession. Interview participants describe accessing firearms primarily through social networks while survey participants also reported access from strangers (25%) and licensed sellers/gun dealers (18%). In conclusion, justice-involved youth believe firearm carriage and possession may be needed for protection due to increasing violence exposure. Further investigation is necessary to determine interventions that may decrease firearm access, carriage, and possession among justice-involved youth.

RESUMO

BACKGROUND: Timely intervention is beneficial to the effectiveness of eating disorder (ED) treatment, but limited capacity within ED services means that these disorders are often not treated with sufficient speed. This service evaluation extends previous research into guided self-help (GSH) for adults with bulimic spectrum EDs by assessing the feasibility, acceptability, and preliminary effectiveness of virtually delivered GSH using videoconferencing. METHOD: Patients with bulimia nervosa (BN), binge eating disorder (BED) and other specified feeding and eating disorders (OSFED) waiting for treatment in a large specialist adult ED out-patient service were offered virtually delivered GSH. The programme used an evidence-based cognitive behavioural self-help book. Individuals were supported by non-expert coaches, who delivered the eight-session programme via videoconferencing. RESULTS: One hundred and thirty patients were allocated to a GSH coach between 1 September 2020 and 30 September 2022; 106 (82%) started treatment and 78 (60%) completed treatment. Amongst completers, there were large reductions in ED behaviours and attitudinal symptoms, measured by the ED-15. The largest effect sizes for change between pre- and post-treatment were seen for binge eating episode frequency (d = -0.89) and concerns around eating (d = -1.72). Patients from minoritised ethnic groups were over-represented in the non-completer group. CONCLUSIONS: Virtually delivered GSH is feasible, acceptable and effective in reducing ED symptoms amongst those with bulimic spectrum disorders. Implementing virtually delivered GSH reduced waiting times, offering a potential solution for long waiting times for ED treatment. Further research is needed to compare GSH to other brief therapies and investigate barriers for patients from culturally diverse groups.

RESUMO

Background and Objectives: Graves' disease (GD) and primary aldosteronism (PA) are two pathologies that can cause significant morbidity and mortality. GD is mediated by autoantibodies, and recent studies have shown autoantibody involvement in the pathophysiology behind both PA and pre-eclampsia. The coexistence of GD and PA, however, is reportedly rare. This report describes a unique case of Graves' hyperthyroidism and concomitant PA in a patient with a history of pre-eclampsia with severe features. Case Presentation: The patient presented at 17 weeks pregnancy with mild hyperthyroidism, negative TSH receptor antibodies, and a low level of thyroid-stimulating immunoglobulins (TSI). Her TSH became detectable with normal thyroid hormone levels, and therefore, no anti-thyroid medication was administered. At 34 weeks she developed pre-eclampsia with severe features, and a healthy child was delivered; her TSH returned to normal. Seven months after delivery, she presented emergently with severe hyperthyroidism, hypertensive crisis, and a serum potassium of 2.5 mmol/L. Her hypertension was uncontrolled on multiple anti-hypertensives. Both TSI and TSH receptor antibodies were negative. The aldosterone(ng/dL)/renin(ng/mL/h ratio was (13/0.06) = 216.7, and abdominal CT imaging demonstrated normal adrenal glands; thus, a diagnosis of PA was made. Her blood pressure was subsequently controlled with only spironolactone at 50 mg 2xday. Methimazole was started but discontinued because of an allergic reaction. Consequently, a thyroidectomy was performed, and pathology revealed Graves' disease. The patient remained well on levothyroxine at 125 mcg/day and spironolactone at 50 mg 2xday three months after the thyroidectomy. Conclusions: This patient manifested severe GD with antibodies undetectable by conventional TSI and TSH receptor assays and accelerated hypertension from PA simultaneously. These conditions were successfully treated separately by spironolactone and thyroidectomy. Autoimmune PA was considered likely given the clinical picture. The diagnosis of PA should be considered in hypertension with GD.

RESUMO

Humans stand out for their capacity to flexibly cooperate, possibly because they understand their partners' role. Researchers have explored if such understanding is unique to humans by assessing whether non-human species wait to manipulate a cooperative apparatus until a delayed partner arrives. If animals do wait, then it is assumed that they recognize the need for a partner. However, success in these tasks may be the result of social facilitation, while failure may be due to poor inhibitory control. Moreover, this approach does not test if animals take their partners' actions into account. Here we trained dogs to press a button simultaneously with their human partner. Afterwards, we tested them in several conditions to disentangle which elements of their partner's behaviour they take into account. Dogs waited to press the button until the delayed partner arrived, the button was available to the partner and the partner acted (pressed the button). We found no relationship between inhibitory control and success. We conclude that dogs are not merely reacting to the presence of their human partners, but are also taking their actions into account when coordinating with them.

RESUMO

AIM: To explore the effects of COVID-19 pandemic restrictions varying in severity and duration on health-related behaviours in children aged 5-17 years. METHODS: We used data from the Royal Children's Hospital National Child Health Poll, an online cross-sectional survey of Australian caregivers. The survey assessed 1222 caregivers' perceived changes in health-related behaviours (physical activity, sleep, screen-time, diet, outdoor activity, family and peer connectedness) of 2011 children aged 5-17 years in a typical week from June to September 2020 (when jurisdictions experienced varying restriction severity and duration) compared to retrospective reports of behaviour before March 2020 (pre-pandemic). To compare the effects of varying restriction severity in Victoria, New South Wales (NSW) and other states and territories on health-related behaviours binary logistic regression was used, adjusting for caregiver demographics and weighted to reflect Australia's parent population. RESULTS: Compared to pre-pandemic, Victoria's restrictions had a greater impact on child health-related behaviours compared to NSW restrictions and an even stronger impact compared to other states and territories which experienced few or no restrictions. A greater proportion of Victorian children reported more recreational screen time (71.3%) than NSW (53.9%) and other states and territories (34.5%) and less physical activity (57.2%) than NSW (30.3%) and other states and territories (26.5%). Victorian children reported less outdoor activity (62.6%) than NSW (32.0%) and other states and territories (25.2%), and less social connectedness (68.0%) than NSW (35.4%) and other states and territories (27.3%). CONCLUSIONS: More severe and longer COVID-19 pandemic restrictions are associated with greater impacts and predominantly more negative impacts to children's health-related behaviours. These should be mitigated through policies and programs to encourage healthier life-styles.

RESUMO

OBJECTIVES: Pediatric procedural sedation (PPS) is a core clinical competency of pediatric emergency medicine (PEM) fellowship training mandated by both the Accreditation Council for Graduate Medical Education and the American Board of Pediatrics. Neither of these certifying bodies, however, offers specific guidance with regard to attaining and evaluating proficiency in trainees. Recent publications have revealed inconsistency in educational approaches, attending oversight, PPS service rotation experiences, and evaluation practices among PEM fellowship programs. METHODS: A select group of PEM experts in PPS, PEM fellowship directors, PEM physicians with educational roles locally and nationally, PEM fellows, and recent PEM fellowship graduates collaborated to address this opportunity for improvement. RESULTS: This consensus driven educational guideline was developed to outline PPS core topics, evaluation methodology, and resources to create or modify a PPS curriculum for PEM fellowship programs. This curriculum was developed to map to fellowship Accreditation Council for Graduate Medical Education core competencies and to use multiple modes of dissemination to meet the needs of diverse programs and learners. CONCLUSIONS: Implementation and utilization of a standardized PPS curriculum as outlined in this educational guideline will equip PEM fellows with a comprehensive PPS knowledge base. Pediatric emergency medicine fellows should graduate with the competence and confidence to deliver safe and effective PPS care. Future study after implementation of the guideline is warranted to determine its efficacy.

RESUMO

Depression, anxiety and eating disorders ("social-emotional disorders") are common during adolescence/emerging adulthood, periods of intense identity development. Despite this, there are few reviews of existing research on the relationship between symptoms of these disorders and ongoing identity development. This study systematically reviewed, narratively synthesized and meta-analyzed longitudinal investigations of the relationship between identity synthesis/confusion and depression, anxiety and eating disorders symptoms during adolescence/emerging adulthood. Three databases (PsycInfo, Medline, Embase) were searched. Study quality was systematically appraised, findings were qualitatively synthesized and (where possible) meta-analyzed. 20 studies (55% "fair" quality, 45% "poor" quality) were identified, including 13,787 participants (54.2% female, mean age = 14.48 years, range 10-29 years). The narrative synthesis found evidence of bidirectional relationships between identity synthesis/confusion and depression, anxiety and eating disorder symptoms. Meta-analyses and meta-regressions of a sub-sample of studies (N = 9) indicated no significant associations between identity synthesis or confusion and anxiety or depression symptoms. More high-quality research is needed before firm conclusions can be drawn.

RESUMO

Unequal outcomes disrupt cooperation in some situations, but this has not been tested in the context of coordination in economic games. To explore this, we tested brown capuchins (Sapajus [Cebus] apella) on a manual version of the Stag Hunt (or Assurance) Game, in which individuals sequentially chose between two options, Stag or Hare, and were rewarded according to their choices and that of their partner. Typically, coordination on Stag results in an equal highest payout, whereas coordinating on Hare results in a guaranteed equal but lower payoff and uncoordinated play results in the lowest payoff when playing Stag. We varied this structure such that one capuchin received double the rewards for the coordinated Stag outcome; thus, it was still both animals' best option, but no longer equally rewarding. Despite the inequality, capuchins coordinated on Stag in 78% of trials, and neither payoff structure nor their partner's choice impacted their decision. Additionally, there was no relationship between self-scratching, a measure of stress in capuchins, and choices. After completing the study, we discovered our reward, cheerios, was sufficiently valuable that in another study, capuchins never refused it, so post hoc we repeated the study using a lower value reward, banana flavored pellets. Capuchins completed only 26% of the pellet trials (compared to 98% with cheerios), constraining our ability to interpret the results, but nonetheless the monkeys showed a decrease in preference for Stag, particularly when they received fewer rewards for the coordinated Stag outcome. These results reinforce capuchins' ability to find coordinated outcomes in the Stag Hunt game, but more work is needed to determine whether the monkeys did not mind the inequality or were unwilling to sacrifice a highly preferred food to rectify it. In either case, researchers should carefully consider the impact of their chosen rewards on subjects' choices.

RESUMO

BACKGROUND: Mindfulness Based Interventions (MBIs) for weight loss and overeating-related behaviours have recently gained popularity. Previous systematic reviews and meta-analyses included studies of variable quality, which hinders interpretation of results. This meta-analysis examined only randomised controlled trials (RCTs) comparing the efficacy of MBIs with control groups primarily encouraging either dietary or exercise-based behavioural change in individuals with overweight/obesity and/or binge eating disorder (BED). METHODS: Using PRISMA guidelines, we systematically reviewed relevant articles in Medline, Psychinfo and EMBASE. Twelve eligible RCTs were identified, with three random-effects meta-analyses conducted on primary outcome measures of body mass (N = 11), mindfulness (N = 7) and BED symptoms (N = 3). RESULTS: MBIs were more efficacious than control in increasing mindfulness scores and decreasing BED symptoms from pre-to post-treatment. However, they were no more efficacious than control in reducing body mass which may be attributed to variability in the duration of interventions. Based on intervention duration, exploratory cumulative meta-analyses revealed that while shorter interventions (i.e., 6 weeks) showed greater reductions in body mass compared to longer interventions (i.e., 24 weeks), longer interventions led to greater improvements in mindfulness scores and BED symptoms. CONCLUSIONS: These results highlight the potential of MBIs to improve obesity-related behaviours compared to lifestyle interventions, but their effects on short-term weight loss remain unclear. Future research with a rigorous methodology should consider long-term follow-ups including body mass and mindfulness-related outcome measures in order to establish the clinical potential of MBIs.

RESUMO

OBJECTIVES: Pediatric procedural sedation (PS) has been performed with increasing frequency by pediatric emergency physicians for recent years. Accreditation Council for Graduate Medical Education Pediatric Emergency Medicine fellowship core competency requirements do not specify the manner in which fellows should become proficient in pediatric PS. We surveyed the variety of training experience provided during fellowship and whether those surveyed felt that their training was sufficient. METHODS: A 35-question survey offered to pediatric emergency fellows and recent (within 10 years) graduates collected data on pediatric PS training during fellowship. A follow-up questionnaire was sent to fellowship directors at programs where fellow or graduate respondents stated that a sedation curriculum that existed asked details of their program. RESULTS: There were 95 respondents to the survey, 62% of which had completed pediatric emergency medicine fellowship training. Of respondents, 65% reported having a formal sedation curriculum during fellowship. Of those who participated in a formal curriculum, 82% of respondents felt comfortable performing sedation, whereas the remaining 18% required additional preceptorship and/or more formal training to feel proficient. Fifty-six percent of respondents reported having to complete a set number of sedations before being allowed to sedate independently. Of 17 programs contacted, 9 fellowship directors responded. All 9 included didactics, 6 (66.6%) of 9 included evidence-based medicine literature review, and 6 (66.6%) of 9 included simulation. Other modalities used included supervised clinical experience in a pediatric sedation unit, a 2-week rotation with a hospital sedation team, online sedation modules, and precepted sedations using each pharmacologic agent including nitrous oxide, ketamine, propofol, and ketamine-propofol combination. Ketamine was the most frequently used agent for sedation (87%). CONCLUSIONS: Pediatric emergency medicine fellowship requirements lack a clearly defined pathway for training in PS. Data collected from both current and former fellows depict inconsistency in training experience and suboptimal comfort level in performing these procedures. We suggest that fellows receive a more comprehensive and varied experience with multiple teaching modalities to improve proficiency with this critical and complex aspect of emergency pediatric care.

RESUMO

OBJECTIVES: To evaluate the safety and feasibility of physical rehabilitation and active mobilization in patients requiring continuous renal replacement therapy in the ICU. DATA SOURCES: Medline, CINAHL, PubMed, Pedro, and Cochrane Library were used to extract articles focused on physical activity and mobility in this population. STUDY SELECTION: Research articles were included in this review if 1) included adult patients greater than or equal to 18 years old requiring continuous renal replacement therapy located in the ICU; 2) described physical rehabilitation, active mobilization, or physical activity deliverables; 3) reported data on patient safety and/or feasibility. The primary outcome was safety, defined as number of adverse events per total number of sessions. DATA EXTRACTION: Five-hundred seven articles were evaluated based on title and abstract with reviewers selecting 46 to assess by full text. Fifteen observational studies were included for final analysis with seven studies focused solely on physical activity in patients requiring continuous renal replacement therapy. DATA SYNTHESIS: Four-hundred thirty-seven adult ICU patients requiring continuous renal replacement therapy participated in some form of physical rehabilitation, physical activity, or active mobilization. Two major adverse events (hypotension event requiring vasopressor and continuous renal replacement therapy tube disconnection, pooled occurrence rate 0.24%) and 13 minor adverse events (pooled occurrence rate 1.55%) were reported during a total of 840 individual mobility or activity sessions. Intervention fidelity was limited by a low prevalence of higher mobility with only 15.5% of incidences occurring at or above level 5 of ICU Mobility Scale (transfer to chair, marching in place or ambulation away from bed, 122/715 reports). Feasibility in the provision of these interventions and/or continuous renal replacement therapy-specific deliverables was inconsistently reported. CONCLUSIONS: Early rehabilitation and mobilization, specifically activity in and near the hospital bed, appears safe and mostly feasible in ICU patients requiring continuous renal replacement therapy. A cautious interpretation of these data is necessary due to limited aggregate quality of included studies, heterogeneous reporting, and overall low achieved levels of mobility potentially precluding the occurrence or detection of adverse events.

RESUMO

With the growing population of adults over age 70 years, clinicians must know how to care appropriately for the increasing number of older patients with cancer. Although older adults have higher rates of surgical complications and chemotherapy-related toxicity, they should not be excluded from treatment opportunities based on age alone. Rather, patients should be assessed for fitness, or functional age, for a more accurate estimation of how they will tolerate treatment. This article discusses considerations clinicians should take into account when developing effective treatment plans that do not compromise quality of life for older patients with cancer.

RESUMO

A transition of content management systems provided Kornhauser Health Sciences Library with an opportunity to redesign the library's website to be more user-friendly, efficient, and visually appealing. A multistage approach was taken: (1) informal interviews of various stakeholders from the library, (2) a redesign using information gained from those stakeholders, and (3) a retrospective comparative usability study. This study was conducted with the goal to inform library staff whether the redesigned website improved accuracy and efficiency of information retrieval through the completion of timed tasks. In addition, user satisfaction was measured through guided interview questions.

RESUMO

Previous studies of nonhuman primates have found relationships between health and individual differences in personality, behavior, and social status. However, despite knowing these factors are intercorrelated, many studies focus only on a single measure, for example, rank. Consequently, it is difficult to determine the degree to which these individual differences are independently associated with health. The present study sought to untangle the associations between health and these individual differences in rhesus macaques (Macaca mulatta). We studied 85 socially housed macaques at the Oregon and California National Primate Research Centers, and used veterinary records to determine the number of injuries and illnesses for each macaque. We measured personality using 12 items from a well-established primate personality questionnaire, performed focal observations of behaviors, and calculated dominance status from directional supplant data. All twelve personality questionnaire items were reliable and were used to represent five of the six personality dimensions identified in rhesus macaques-Dominance, Confidence, Openness, Anxiety, and Friendliness (also known as Sociability). Following this, we fit generalized linear mixed effects models to understand how these factors were associated with an animal's history of injury and history of illness. In the models, age was an offset, facility was a random effect, and the five personality dimensions, behavior, sex, and dominance status were fixed effects. Number of injuries and illnesses were each best represented by a negative binomial distribution. For the injury models, including the effects did improve model fit. This model revealed that more confident and more anxious macaques experienced fewer injuries. For the illness models, including the fixed effects did not significantly improve model fit over a model without the fixed effects. Future studies may seek to assess mechanisms underlying these associations.

RESUMO

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) tubes allow for long-term enteral feeding. Disk-retained PEG tubes may be suitable for long-term usage without planned replacement, but data on longevity are limited. We aimed to assess the rates and predictors of PEG longevity and post-PEG mortality. DESIGN: Single-centred retrospective cohort study of patients with disk-retained (Freka) PEG tubes. METHODS: All patients undergoing PEG between 2010 and 2013 were identified, and retrospective analysis of outcomes until 2017 (median 1062 days) was performed. Time-to-event data were plotted using Kaplan-Meier curves, with predictors of survival derived from multivariate Cox-regression analyses. RESULTS: 277patients were studied, with a median age of 74 years (IQR 59-82). PEG tube failure occurred in 17.4%, due to: buried bumper syndrome (7.0%), split/broken tube (6.3%), peristomal infection (1.8%) and dislodged tube (1.1%). PEG tube longevity was 95.1% (1 year) and 68.5% (5 year), with age <70 (HR 2.65, 95% CI 1.25 to 5.62, p=0.011) being predictive of PEG failure. Post-PEG mortality was 10.5% (30 day), 35.4% (1 year) and 59.7% (5 year). Age ≥70 was associated with mortality (HR 2.79, 95% CI 1.92 to 4.05, p<0.001), whereas PEG failure (HR 0.46, 95% CI 0.27 to 0.77, p=0.003) and elective PEG removal (HR 0.23, 95% CI 0.08 to 0.64, p=0.005) were associated with reduced mortality. CONCLUSIONS: 68.5% of PEG tubes remain intact after 5 years. Younger age was associated with earlier PEG failure, whereas younger age, PEG replacement and elective PEG tube removal were associated with improved survival. These data may inform future guidance for elective PEG tube replacements.
