Relationship of Self-reported Attentional Fatigue to Perceived Work Ability in Breast Cancer Survivors
Background: Breast cancer survivors (BCSs) have identified attentional fatigue, a decrease in the ability to focus, as a persistent daily challenge; however, little is known regarding its impact on work ability.
Objective: The purpose of this study was to examine the relationship between attentional fatigue and perceived work ability in BCSs controlling for the known covariates of age, education, household income, and time posttreatment.
Methods: A cross-sectional, descriptive design was used. Breast cancer survivors who were currently employed and at least 1 year post-adjuvant treatment participated. Breast cancer survivors completed the Attentional Function Index and Work Ability Index questionnaires. Descriptive statistics, linear regression, and Fisher exact test were used for analysis.
Results: Sixty-eight female BCSs, ranging from 29 to 68 years of age (mean, 52.1 [SD, 8.6]) and on average 4.97 (SD, 3.36) years posttreatment, participated. More than one-fourth of BCSs (26.5%) reported poor to moderate perceived work ability, indicating substantial concerns regarding work performance. Attentional fatigue was found to significantly predict perceived work ability (P < .001), explaining 40% of the variance of perceived work ability.
Conclusions: Attentional fatigue is a prevalent symptom posttreatment that is negatively related to perceived work ability in BCSs.
Implications for Practice: Nurses are in a prime position to assess and intervene to alleviate attentional fatigue to improve work ability. Findings suggest a need for individual, comprehensive survivorship care plans to effectively address symptoms that impact work ability and, ultimately, the quality of life of cancer survivors
C-Jun N-terminal kinase controls TDP-43 accumulation in stress granules induced by oxidative stress
<p>Abstract</p> <p>Background</p> <p>TDP-43 proteinopathies are characterized by loss of nuclear TDP-43 expression and formation of C-terminal TDP-43 fragmentation and accumulation in the cytoplasm. Recent studies have shown that TDP-43 can accumulate in RNA stress granules (SGs) in response to cell stresses and this could be associated with subsequent formation of TDP-43 ubiquinated protein aggregates. However, the initial mechanisms controlling endogenous TDP-43 accumulation in SGs during chronic disease are not understood. In this study we investigated the mechanism of TDP-43 processing and accumulation in SGs in SH-SY5Y neuronal-like cells exposed to chronic oxidative stress. Cell cultures were treated overnight with the mitochondrial inhibitor paraquat and examined for TDP-43 and SG processing.</p> <p>Results</p> <p>We found that mild stress induced by paraquat led to formation of TDP-43 and HuR-positive SGs, a proportion of which were ubiquitinated. The co-localization of TDP-43 with SGs could be fully prevented by inhibition of c-Jun N-terminal kinase (JNK). JNK inhibition did not prevent formation of HuR-positive SGs and did not prevent diffuse TDP-43 accumulation in the cytosol. In contrast, ERK or p38 inhibition prevented formation of both TDP-43 and HuR-positive SGs. JNK inhibition also inhibited TDP-43 SG localization in cells acutely treated with sodium arsenite and reduced the number of aggregates per cell in cultures transfected with C-terminal TDP-43 162-414 and 219-414 constructs.</p> <p>Conclusions</p> <p>Our studies are the first to demonstrate a critical role for kinase control of TDP-43 accumulation in SGs and may have important implications for development of treatments for FTD and ALS, targeting cell signal pathway control of TDP-43 aggregation.</p
The Morphological Butcher-Oemler effect in the SDSS Cut&Enhance Galaxy Cluster Catalog
We investigate the evolution of the fractions of late type cluster galaxies
as a function of redshift, using one of the largest, most uniform cluster
samples available. The sample consists of 514 clusters of galaxies in the range
0.02<z<0.3 from the Sloan Digital Sky Survey Cut & Enhance galaxy cluster
catalog. This catalog was created using a single automated cluster finding
algorithm on uniform data from a single telescope, with accurate CCD
photometry, thus, minimizing selection biases. We use four independent methods
to analyze the evolution of the late type galaxy fraction. Specifically, we
select late type galaxies based on: restframe g-r color, u-r color, galaxy
profile fitting and concentration index. The first criterion corresponds to the
one used in the classical Butcher-Oemler analyses. The last three criteria are
more sensitive to the morphological type of the galaxies. In all four cases, we
find an increase in the fraction of late type galaxies with increasing
redshift, significant at the 99.9% level. The results confirm that cluster
galaxies do change colors with redshift (the Butcher-Oemler effect) and, in
addition, they change their morphology to later-type toward higher redshift --
indicating a morphological equivalent of the Butcher-Oemler effect. We also
find a tendency of richer clusters to have lower fractions of late type
galaxies. The trend is consistent with a ram pressure stripping model, where
richer clusters have more effective ram pressure due to their higher
temperature.Comment: 44 pages, 15 figures, accepted for PAS
Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial
Background
Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
The state of the Martian climate
60°N was +2.0°C, relative to the 1981â2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes
Psychiatric and medical comorbidities of eating disorders : findings from a rapid review of the literature
Background: Eating disorders (EDs) are potentially severe, complex, and life-threatening illnesses. The mortality rate
of EDs is signifcantly elevated compared to other psychiatric conditions, primarily due to medical complications and
suicide. The current rapid review aimed to summarise the literature and identify gaps in knowledge relating to any
psychiatric and medical comorbidities of eating disorders.
Methods: This paper forms part of a rapid review) series scoping the evidence base for the feld of EDs, conducted
to inform the Australian National Eating Disorders Research and Translation Strategy 2021â2031, funded and released
by the Australian Government. ScienceDirect, PubMed and Ovid/Medline were searched for English-language studies
focused on the psychiatric and medical comorbidities of EDs, published between 2009 and 2021. High-level evidence
such as meta-analyses, large population studies and Randomised Control Trials were prioritised.
Results: A total of 202 studies were included in this review, with 58% pertaining to psychiatric comorbidities and
42% to medical comorbidities. For EDs in general, the most prevalent psychiatric comorbidities were anxiety (up
to 62%), mood (up to 54%) and substance use and post-traumatic stress disorders (similar comorbidity rates up to
27%). The review also noted associations between specifc EDs and non-suicidal self-injury, personality disorders, and
neurodevelopmental disorders. EDs were complicated by medical comorbidities across the neuroendocrine, skeletal,
nutritional, gastrointestinal, dental, and reproductive systems. Medical comorbidities can precede, occur alongside or
emerge as a complication of the ED.
Conclusions: This review provides a thorough overview of the comorbid psychiatric and medical conditions cooccurring with EDs. High psychiatric and medical comorbidity rates were observed in people with EDs, with comorbidities contributing to increased ED symptom severity, maintenance of some ED behaviours, and poorer functioning
as well as treatment outcomes. Early identifcation and management of psychiatric and medical comorbidities in
people with an ED may improve response to treatment and overall outcomes
Informing the development of Australia's national eating disorders research and translation strategy : a rapid review methodology
Background Eating disorders (EDs) are highly complex mental illnesses associated with significant medical complications. There are currently knowledge gaps in research relating to the epidemiology, aetiology, treatment, burden, and outcomes of eating disorders. To clearly identify and begin addressing the major deficits in the scientific, medical, and clinical understanding of these mental illnesses, the Australian Government Department of Health in 2019 funded the InsideOut Institute (IOI) to develop the Australian Eating Disorder Research and Translation Strategy, the primary aim of which was to identify priorities and targets for building research capacity and outputs. A series of rapid reviews (RR) were conducted to map the current state of knowledge, identify evidence gaps, and inform development of the national research strategy. Published peer-reviewed literature on DSM-5 listed EDs, across eight knowledge domains was reviewed: (1) population, prevalence, disease burden, Quality of Life in Western developed countries; (2) risk factors; (3) co-occurring conditions and medical complications; (4) screening and diagnosis; (5) prevention and early intervention; (6) psychotherapies and relapse prevention; (7) models of care; (8) pharmacotherapies, alternative and adjunctive therapies; and (9) outcomes (including mortality). While RRs are systematic in nature, they are distinct from systematic reviews in their aim to gather evidence in a timely manner to support decision-making on urgent or high-priority health concerns at the national level. Results Three medical science databases were searched as the primary source of literature for the RRs: Science Direct, PubMed and OVID (Medline). The search was completed on 31st May 2021 (spanning January 2009-May 2021). At writing, a total of 1,320 articles met eligibility criteria and were included in the final review. Conclusions For each RR, the evidence has been organised to review the knowledge area and identify gaps for further research and investment. The series of RRs (published separately within the current series) are designed to support the development of research and translation practice in the field of EDs. They highlight areas for investment and investigation, and provide researchers, service planners and providers, and research funders rapid access to quality current evidence, which has been synthesised and organised to assist decision-making

Parental experiences of supporting children with clinically significant post-traumatic distress: a qualitative study of families accessing psychological services
The aim of this study was to investigate the experiences of parents in providing support to their child following trauma exposure in cases where children are experiencing clinically significant levels of post-traumatic distress. Qualitative interviews were conducted with parents whose child was exposed to a trauma and referred for psychological treatment. Parents reported considerable anxiety in coping with their childâs post-traumatic distress. Avoidance of trauma-related discussions was encouraged due to concerns that non-avoidant approaches may worsen childrenâs post-trauma difficulties. Nonetheless, parents were often sensitive to their childâs distress and offered reassurance and other forms of support. Many barriers existed to accessing psychological treatment, and perceptions of inadequate guidance from therapists on supporting child adjustment contributed to parental distress. The results illustrate the strategies used by parents in supporting their child post-trauma and may assist mental health professionals in providing acceptable guidance to parents following child trauma
A multi-centre randomized controlled trial comparing arthroscopic osteochondroplasty and lavage with arthroscopic lavage alone on patient important outcomes and quality of life in the treatment of young adult (18-50) Femoroacetabular impingement
Background: Several cross-sectional studies have estimated that the prevalence of femoroacetabular impingement (FAI) ranges from 14-17% among asymptomatic young adults to almost 95% among competitive athletes. With FAI, there is abnormal contact between the proximal femur and the acetabulum, resulting in abnormal mechanics with terminal motion such as hip flexion and rotation. This condition results from bony anomalies of the acetabular rim (Pincer) and or femoral head/neck junction (CAM) and typically causes hip pain and decreased hip function. The development of hip pain potentially serves as an indicator for early cartilage and labral damage that may result in hip osteoarthritis. Although surgical correction of the misshaped bony anatomy and associated intra-articular soft tissue damage of the hip is thought to improve hip pain and alter the natural history of degenerative disease, the supportive evidence is based upon low quality observational studies. The Femoroacetabular Impingement RandomiSed controlled Trial (FIRST) compares outcomes following surgical correction of the impingement morphology (arthroscopic osteochondroplasty) with/without labral repair versus arthroscopic lavage of the hip joint in adults aged 18 to 50 diagnosed with FAI. Methods and design: FIRST is a multi-centre, randomized controlled trial with a sample size of 220 patients. Exclusion criteria include the presence of hip syndromes, previous surgery or trauma to the affected hip, and significant medical comorbidities. The primary outcome is pain and the secondary outcomes include patient function, quality of life, complications, and cost-effectiveness - all within one year of follow-up. Patients are stratified based on centre and impingement sub-type. Patients, outcome assessors, data analysts, and the Steering Committee are blinded to surgical allocation. Using an intention-to-treat approach, outcome analyses will be performed using an analysis of covariance and descriptive statistics. Discussion: Symptomatic FAI is associated with chronic hip pain, functional limitations, and secondary osteoarthritis. Therefore, optimizing treatment has the potential to improve the lives millions of young, active persons who are diagnosed with this condition. Few orthopaedic surgical trials have similar potential to shift the paradigm of care dramatically towards (or away) from surgical bony and soft tissue interventions.Peer reviewe
