Authors: Hosozawa Mariko , Sacker Amanda , Cable Noriko 
Published: August 2020

This exploratory study aimed to explore the association between depression and self-harming behaviour in adolescence and the timing of diagnosis for autism spectrum disorder. We analysed data on 11,320 14 year olds, including 396 children with autism spectrum disorder, from the UK Millennium Cohort Study. Exposures were the timing of diagnosis for autism spectrum disorder confirmed by parental report at ages 5, 7, 11 and 14. Outcomes were depression measured by the Short Mood and Feelings Questionnaire (scores ⩾12) and self-report of self-harming behaviour, both assessed at age 14. Data were analysed using multivariable regression analysis. 91% of the autism spectrum disorder group had within-typical-range cognitive ability. After adjusting for child and family confounders, there was a positive linear trend between diagnostic age and depression, with children diagnosed between ages 7 and 11 and children diagnosed after age 11 showing increased symptoms (odds ratio = 2.21 and 3.58, respectively). A similar trend was observed for self-harming behaviour, with children diagnosed after age 11 showing the strongest association (odds ratio = 3.16). These results suggest the importance of earlier diagnosis in preventing secondary mental health problems in this population, particularly among those without cognitive delays. Further studies replicating across a wider intellectual spectrum and clarifying the underlying mechanism are warranted. Lay Abstract Children with autism spectrum disorder are at increased risk of depression and self-harming behaviours. The question of whether timing of diagnosis of autism spectrum disorder is associated with these consequences in adolescence has not yet been studied. This exploratory study aimed to explore the association between depression and self-harming behaviour in adolescence and the parent-reported timing of diagnosis for autism spectrum disorder using a large population-based cohort in the United Kingdom. Most of the children with autism spectrum disorder in our study had within-typical-range cognitive ability. We found a linear association between timing of autism spectrum disorder diagnosis and depression and self-harming behaviour in adolescence; later diagnosis of autism spectrum disorder, particularly diagnosis in adolescence, was associated with the increased risk of self-reported depressive symptoms and self-harming behaviour in adolescence among children with autism spectrum disorder. Our findings, albeit observational, suggest that interventions targeting the earlier diagnosis of autism spectrum disorder and approaches to improve person–environment fit may help prevent secondary mental health problems in this population, particularly among those without cognitive delays and those diagnosed late. Further studies replicating across a wider intellectual spectrum and clarifying the underlying mechanism are warranted.
Interrogating empathy in two long form texts: a comparative textual analysis of trauma affect
Authors: Joseph Sue 
Published: August 2020

There are three traditional categories of empathy – emotional, cognitive and compassionate or radical. For decades, empathy was seen as the antithesis of any kind of good journalism; that the journalist must at all times maintain detachment in order to do her job. But this paper interrogates, through the textual analysis of two Australian long form texts, including several epitextual artefacts, how empathy can perform as an evocative tool of narrative literary journalism creating richer and deeper meaning and depth of understanding. Both texts are hybrids of the form, mixing narrative inquiry, reportage and personal reflective practice. Here I argue that the first text conflates emotional and compassionate empathy, while the second privileges cognitive and radical empathy, ultimately and startlingly advocating compassionate empathy. Both provide for their audience an intimate glimpse into the private lives of others affected by trauma or occupying a particular place in cyberspace.
Towards an increased understanding of reminiscence therapy for people with dementia: A narrative analysis

Published: August 2020

Aim Reminiscence therapy is a popular therapeutic intervention for people with dementia. This review set out to provide a better understanding of reminiscence therapy through a deeper analysis of its contents and delivery. Method This review examined 22 studies from the most recent Cochrane review (Woods, B., O’Philbin, L., Farrell, E. M., Spector, A. E., & Orrell, M. (2018). Reminiscence therapy for dementia. Cochrane Database of Systematic Reviews, 3, Article 001120) and addressed the following research questions: (1) What are the components of reminiscence therapy? (2) Who delivers reminiscence therapy? (3) How is reminiscence therapy delivered? (4) Is reminiscence therapy underpinned by a theoretical framework? (5) Is reminiscence therapy delivered according to a programme/model? (6) Are there commonalities in the reminiscence therapy components utilised? Multiple and layered narrative analyses were completed. Findings Thirteen reminiscence therapy components were identified. ‘Memory triggers’ and ‘themes’ were identified as the most common but were found not to be consistently beneficial. Reminiscence therapy was typically delivered in a care setting using a group approach; however, there was no consistency in session composition, intervention duration, as well as the training and supervision provided to facilitators. Operationalisation of theory within reminiscence therapy was not identified. Reminiscence therapy was not consistently delivered according to a programme/model. Lastly, as a result of a small number of studies, the components ‘life stages’, ‘activities’ and ‘family-only sessions’, showed beneficial promise. In summary, this review highlights that reminiscence therapy needs more consistency in content and delivery, in addition to a clear theoretical framework.

Published: August 2020

Background Proximal interphalangeal joint (PIPJ) arthrodesis can provide reliable pain relief and restore hand function in patients with PIPJ arthritis. However, there is a paucity of literature on patient-specific preoperative risk factors that are associated with adverse outcomes after PIPJ arthrodeses. Therefore, the primary purpose of this study was to assess preoperative predictors of nonunion and reoperation after PIPJ arthrodesis. Methods This study identified all patients who underwent PIPJ arthrodesis at a single community practice between 1987 and 2013. The final analysis included 415 PIPJs treated with arthrodesis. The mean follow-up was 1.3 years. Data on preoperative diagnosis, demographics, comorbidities, and operative techniques were recorded, as well as the occurrence of nonunions and reoperations. Logistic regression models were used to identify independent risk factors of nonunion and reoperation. Results There were 40 nonunions (10%) and 62 reoperations (15%). Of the reoperations, there were 39 incidences of isolated hardware removal, 9 irrigation and debridement, 8 amputations, 5 revision arthrodeses, and 1 corrective osteotomy. The highest number of nonunions occurred in the traumatic diagnosis group (37%), followed by the rheumatoid group (23%) and the scleroderma group (15%). The highest number of reoperations occurred within the traumatic joint disorder group (40%), followed by the rheumatoid group (24%) and the scleroderma group (11%). Multivariate analysis revealed that male sex ( P < .01) and hepatic disease ( P = .03) were significant risk factors of nonunion. Male sex was also significantly associated with increased reoperation risk ( P < .01). Conclusion Risks of nonunions and reoperations after PIPJ arthrodeses are low; however, these findings may guide clinicians and patients in the preoperative decision-making process and help with targeted postoperative surveillance to mitigate these risks.

Published: August 2020

Background Ulnar metacarpal base fractures can destabilize the carpometacarpal (CMC) joint, prompting surgical stabilization. Studies investigating this injury are limited by small case volumes. Our purpose is to review the surgical techniques, outcomes, and complications of ulnar CMC joint stabilization. Methods A literature search was performed of all articles published on the surgical treatment and outcomes of ulnar CMC fracture dislocations using PubMed and Google Scholar databases between the years 2014 and 2019. Data were pooled and analyzed, assessing surgical techniques and hand outcome measures: union, recurrent dislocations, range of motion, grip strength, and complications. Results Six studies met inclusion criteria. All surgical patients, regardless of technique, went on to union with no incidents of recurrent instability. Grip strength was significantly decreased postoperatively (82.7% of uninjured side). Patients with CMC dislocations of both the fourth and fifth ray had similar postoperative outcomes to those with CMC dislocations of the fifth ray alone. One third of plate and screw constructs required plate removal, due to breakage (2) or implant-related pain (4). Plate-related symptoms resolved after removal in all cases. Delayed treatment decreased the effectiveness of nonoperative treatment, and increased the likelihood of postoperative pain, chronic deformity, malunion, and CMC osteoarthritis. Conclusions Closed reduction percutaneous pinning, open reduction percutaneous pinning, and open reduction internal fixation with CMC joint bridging or dorsal buttress plating are all well described, safe techniques with low complication rates. Early, accurate diagnosis of fourth and fifth CMC joint fracture-dislocations is crucial for optimizing hand function and postoperative outcomes.

Published: August 2020

Background The INFINITY total ankle prothesis remains the most widely used fourth-generation total ankle arthroplasty (TAA) system in the United States. The purpose of the present study was to assess radiographic outcomes for INFINITY at short-term follow-up. Methods All patients who underwent primary TAA with INFINITY between August 2015 and June 2018 at a single institution and who were at least 1 year postoperative were included. A total of 55 ankles with a mean follow up 22 months (range, 12-43 months) met the criteria. Weightbearing radiographs were assessed using coronal and sagittal alignment parameters preoperatively, at 6 to 8 weeks postoperatively, and at the most recent follow-up. Medical records and charts were reviewed and revisions, reoperations, and complications were classified according to the criteria established by Vander Griend et al and Glazebrook at el, respectively. Results Overall, INFINITY survivorship was 98.2%. Coronal and sagittal tibiotalar alignment improved after surgery ( P < .001, P = .09, respectively), and was maintained during the latest follow-up ( P = .62, P = .47, respectively). Only 1 ankle (1.8%) required early revision; while 5 (9.1%) indicated non-implant-related revision; 85.5% required no reoperation. In nineteen ankles (34.5%), postoperative periprosthetic lucency was observed; most were not progressive (17 ankles, 89.5%). Twelve complications (3 high grade, 3 intermediate, and 6 low grade) in 11 ankles (20%) were recorded according to the Glazebrook classification system. Conclusion INFINITY survivorship was 98.2% at a mean of 1.8 years of follow-up, and only 1 ankle required prosthetic revision. Additional studies with longer follow-up are warranted for fourth-generation TAA prostheses. Levels of Evidence: Level IV: Case series
Social Support in the Peritoneal Dialysis Experience: A Qualitative Descriptive Study
Authors: Fox Danielle E. , Quinn Robert R. , James Matthew T. , Venturato Lorraine , King-Shier Kathryn M. 
Published: August 2020

Background: People with end-stage kidney disease can either pursue conservative (palliative) management or kidney replacement therapy. Although transplant is preferred, there is a limited number of organs available rendering the majority of patients treated with some form of dialysis. Hemodialysis and peritoneal dialysis are equivalent regarding clinical outcomes, but peritoneal dialysis is much less costly to provide. Peritoneal dialysis is most often done in the home by the patient or a support person and carries a self-care burden on patients and families. Social support is important for patients receiving peritoneal dialysis and in sustaining peritoneal dialysis therapy. Few studies have comprehensively explored social support in the context of peritoneal dialysis. Objective: To explore how patients, family members, and nurses view social support. Design: Qualitative, descriptive study. Setting: An outpatient peritoneal dialysis clinic in Western Canada. Participants: Patients, family members, and nurses. Methods: Patients (n = 15), family members (n = 6), and nurses (n = 11) were interviewed between January and May 2018. Content analysis was undertaken using 4 attributes of social support (ie, emotional support, instrumental support, informational support, and appraisal support) as an analytic framework. Results: Themes related to the 4 attributes of social support were identified: addressing emotional needs and managing emotion (emotional support); peritoneal dialysis tasks and life tasks (instrumental support); accessing information, receiving information, and learning (informational support); and affirmation/external reassurance and self-confidence (appraisal support). The social support needs of both patients and family members varied and were dependent on their existing support networks and individual perspectives of support. Limitations: It is possible that some of the study findings were gender-bound as well as context-specific. The study findings could be different if the patient and caregiver sample were more balanced based on sex. There are also unique attributes of each peritoneal dialysis program that may impact the transferability of these findings to other practice settings. Conclusion: Home-based peritoneal dialysis has potential benefit to patients and health care systems. However, receiving peritoneal dialysis requires support. If health care providers wish to promote this treatment, they must also understand how to best support patients and their family members. Trial Registration: Not applicable.

Abstract
Background
Competition is a common social interaction among shrimp and depending on its intensity, it can affect heritable variation and response to selection. Little is known about the variance of indirect genetic effects (IGE) under competitive and non-competitive conditions in shrimp. In this study, we used extended mixed linear models to estimate genetic parameters for the direct genetic effect (DGE) and IGE on body weight in Litopenaeus vannamei raised under ad libitum (AF, non-competitive environment) and restricted (RF, competitive environment) feeding regimes.

Results
Estimates of heritabilities for body weight obtained with a traditional animal model (i.e. without accounting for IGE) were 0.11 ± 0.09 under AF and 0.25 ± 0.11 under RF. With extended animal models that accounted for IGE, the corresponding estimates for body weight were 0.07 ± 0.08 and 0.34 ± 0.11. Thus, heritabilities were higher under the RF regime than under the AF regime, regardless of whether IGE was accounted for or not. The log-likelihood ratio test revealed significant IGE under the RF regime. Although estimates of indirect genetic variance were low (0.0023 ± 0.0013 for AF and 0.0028 ± 0.0012 for RF), they contributed substantially to the total heritable variance: 66.8% for AF and 692.2% for RF. The total heritable variance was smaller under the RF regime (0.7 ± 1.3) than under the AF regime (5.8 ± 2.6) because of the high contribution of the negative covariance between DGE and IGE (− 7.03). Estimates of the correlation between DGE and IGE were 0.32 ± 0.47 under AF and − 0.93 ± 0.15 under RF, those of DGE and IGE for body weight between both regimes were 0.94 ± 0.07 and 0.67 ± 0.20, respectively, and those of IGE for body weight with DGE for survival were − 0.12 ± 0.22 under AF and − 0.58 ± 0.20 under RF.

Conclusions
These results indicate that strong competitive interactions occurred under the RF regime in L. vannamei. Significant reranking and variation in IGE of individuals were observed between the two feeding regimes. Strong competitive interactions reduced the total heritable variation for body weight when food was restricted. These results indicate that the extent of competition among L. vannamei depends on the feeding regime applied and that this competition affects the genetic basis of body weight.
Distinct evolutionary trajectories of V1R clades across mouse species
Authors: Miller Caitlin H. , Campbell Polly , Sheehan Michael J. 
Published: August 2020

Abstract
Background
Many animals rely heavily on olfaction to navigate their environment. Among rodents, olfaction is crucial for a wide range of social behaviors. The vomeronasal olfactory system in particular plays an important role in mediating social communication, including the detection of pheromones and recognition signals. In this study we examine patterns of vomeronasal type-1 receptor (V1R) evolution in the house mouse and related species within the genus Mus. We report the extent of gene repertoire turnover and conservation among species and clades, as well as the prevalence of positive selection on gene sequences across the V1R tree. By exploring the evolution of these receptors, we provide insight into the functional roles of receptor subtypes as well as the dynamics of gene family evolution.

Results
We generated transcriptomes from the vomeronasal organs of 5 Mus species, and produced high quality V1R repertoires for each species. We find that V1R clades in the house mouse and relatives exhibit distinct evolutionary trajectories. We identify putative species-specific gene expansions, including a large clade D expansion in the house mouse. While gene gains are abundant, we detect very few gene losses. We describe a novel V1R clade and highlight candidate receptors for future study. We find evidence for distinct evolutionary processes across different clades, from largescale turnover to highly conserved repertoires. Patterns of positive selection are similarly variable, as some clades exhibit abundant positive selection while others display high gene sequence conservation. Based on clade-level evolutionary patterns, we identify receptor families that are strong candidates for detecting social signals and predator cues. Our results reveal clades with receptors detecting female reproductive status are among the most conserved across species, suggesting an important role in V1R chemosensation.

Conclusion
Analysis of clade-level evolution is critical for understanding species’ chemosensory adaptations. This study provides clear evidence that V1R clades are characterized by distinct evolutionary trajectories. As receptor evolution is shaped by ligand identity, these results provide a framework for examining the functional roles of receptors.
A novel path-specific effect statistic for identifying the differential specific paths in systems epidemiology

Published: August 2020

Abstract
Background
Biological pathways play an important role in the occurrence, development and recovery of complex diseases, such as cancers, which are multifactorial complex diseases that are generally caused by mutation of multiple genes or dysregulation of pathways.

Results
We propose a path-specific effect statistic (PSE) to detect the differential specific paths under two conditions (e.g. case VS. control groups, exposure Vs. nonexposure groups). In observational studies, the path-specific effect can be obtained by separately calculating the average causal effect of each directed edge through adjusting for the parent nodes of nodes in the specific path and multiplying them under each condition. Theoretical proofs and a series of simulations are conducted to validate the path-specific effect statistic. Applications are also performed to evaluate its practical performances. A series of simulation studies show that the Type I error rates of PSE with Permutation tests are more stable at the nominal level 0.05 and can accurately detect the differential specific paths when comparing with other methods. Specifically, the power reveals an increasing trends with the enlargement of path-specific effects and its effect differences under two conditions. Besides, the power of PSE is robust to the variation of parent or child node of the nodes on specific paths. Application to real data of Glioblastoma Multiforme (GBM), we successfully identified 14 positive specific pathways in mTOR pathway contributing to survival time of patients with GBM. All codes for automatic searching specific paths linking two continuous variables and adjusting set as well as PSE statistic can be found in supplementary materials.

Conclusion
The proposed PSE statistic can accurately detect the differential specific pathways contributing to complex disease and thus potentially provides new insights and ways to unlock the black box of disease mechanisms.
