Decline of young-of-year walleye (Sander vitreus) growth due to Bythotrephes impacts predicted from bioenergetic principles
Authors: Gartshore Danni J , Rennie Michael D. 
Published: December 2022

Abstract
Invasive species are a major threat to ecosystem structure and function. For example, Bythotrephes cederströmii (Bythotrephes hereafter) invasions have significantly reduced native zooplankton density and biomass, resulting in competitive interactions with zooplanktivorous fishes. Young of year (YOY) walleye (Sander vitreus) are initially zooplanktivorous and have recently been shown to display reduced growth in Bythotrephes invaded lakes. Here, we combined a bioenergetics model for larval walleye with changes in the zooplankton community following Bythotrephes invasion and predicted reduced larval walleye growth in the presence of Bythotrephes, supporting field observations. The model predicted greater impacts in oligotrophic versus mesotrophic lakes, whereby Bythotrephes invasion could potentially lead to walleye recruitment failure in low nutrient environments. As YOY growth, survival, and recruitment are ultimately linked to adult abundance and sustainability of managed stocks, our results highlight the potential impacts of Bythotrephes on the sustainability of walleye populations in boreal lakes.
Hurricane events facilitate the establishment of nonnative invertebrate species in harbors
Authors: Hutchings Brenna , Stiles Emma , Lopez-Legentil Susanna 
Published: December 2022

Abstract
The coastal location and shallow depths of harbors suggest that fouling communities will be greatly affected by extreme weather events. Within fouling communities, ascidians are conspicuous animals and their sessile nature makes them ideal targets to assess community resilience. We established ascidian diversity and abundance at eighteen harbors and marinas along the coast of North Carolina (United States) a year after Hurricane Florence landfall in 2018 (post-hurricane) and compared results with those obtained in 2014 (pre-hurricane). The distribution and community structure of native and introduced ascidians were analyzed using presence-absence and relative abundance similarity matrices. Both geographic location (North vs. South) and distance between harbors had a significant effect on ascidian community composition. When compared with pre-hurricane data, a decrease in the number of native species and an increase of introduced and cryptogenic species was noted, although these trends were only statistically significant for the number of introduced species based on presence-absence data. Monthly photo transects spanning pre- and post-hurricane periods to monitor the ascidian community at the harbor located where the hurricane made landfall, revealed that all but one species disappeared from the docks after the hurricane. Recolonization occurred slowly, and one year later, only two non-native species were present. Further, we report the arrival of the globally introduced species Styela canopus and Distaplia listerianum in North Carolina. This study significantly advances our understanding of the impact of hurricanes on fouling communities inhabiting harbors and the speed of natural recovery.

Published: December 2022

Abstract
Background

Arthroscopic technique procedures was wide accepted for the treatment of chronic ankle instability (CAI). But little acknowledge was involved to the bony landmarks and anatomic features of different bundles of lateral ligaments under arthroscopic view.

Methods

Sixty patients with acute or chronic lateral ankle ligaments injury (LAI) were collected prospectively, and divided randomly into two groups. In arthroscopic group, the bone tunnels were made on the LPF arthroscopically. And in open group, the bone tunnels were made on the Fibular obscure tubercle (FOT) in open procedure. The inferior bundle of ATFL and Arcuate fibre was also identified reference to the LPF and labeled by a PDS II suture penetration. Following that, The distances of the bone tunnels to the different bony markers were measured and compare between two groups. The penetrating locations of PDS II on the inferior bundle of ATFL and Arcuate fibre were also confirmed intraoperatively. And the safe angle of anchor implantation on the axial view was measured on postoperative CT scan.

Results

The distances of bone tunnel to the fibular tip, the fibular insertion of anterior-inferior tibiofibular ligament (AITFL), and the FOT in arthroscopic and open locating groups were 4.9 ± 2.2 and 6.3 ± 2.2mm, 13.5 ± 2.7 and 12.4 ± 1.1mm, 5.8 ± 2.2 and 5.6 ± 1.0mm, respectively. The distances of bone tunnels to the FOT and fibular tip on 3d-CT view was 4.4 ± 1.5 and 4.6 ± 0.9 mm, 14.4 ± 3.2 and 13.2 ± 1.8 mm in arthroscopic and open group, and there were no significant differences between two groups. The safe angle of arthroscopic anchor placement on the axial plan was ranged from 24.9 ± 6.3o to 58.1 ± 8.0o. The PDS II sutures penetrating on the inferior bundles of ATFL and the arciform fibres were also comfirmed successfully by open visualizaion.The average distance of penetration point to the horizontal line cross the fibular tip was 2.3 ± 2.7 mm (ranged from − 3.1 to 6.0 mm), and to the vertical line cross the FOT was 2.7 ± 2.7 mm (ranged from − 2.5 to 7.5 mm).

Conclusion

Take the lowest point of fibula under arthroscopy (LPF) as a bony reference, we could identify the iATFL under arthroscopic visualization. By this way, we could place the suture anchors properly to the fibular footprint and suture the iATFL fibres successfully.

A scoping review on two-stage randomized preference trial in mental health
Authors: Chen Sheng , Wang Wei 
Published: December 2022

Abstract
Background: Randomized Controlled Trial is the most rigorous study design to test the efficacy and effectiveness of an intervention. Patient preference may negatively affect patient performance and decrease the generalizability of a trial to clinical population. Patient preference trial have particular implications in mental health since mental health interventions are generally complex, blinding of intervention is often difficult or impossible, patients may have strong preference, and outcome measures are often subjective patient self-report which may be greatly influenced if patient’s preference did not match with the intervention received.
Methods: In this review, we have surveyed the application of two-stage randomized preference trial with focus on studies in the field of mental health. The study selection followed guideline provided by Preferred Reporting Items for Systematic Reviews and Meta-Analysis.
Results: Six two-stage randomized preference trials (ten publications) have been identified in the mental health field. In these trials, the pooled dropout rates were 18.3% for the preference arm, and 28.7% for the random arm, with a pooled RR of 0.70 (95% CI, 0.56-0.88; P=0.010) indicating significantly lower risk of dropout in the preference arm. The standardized preference effects varied widely from 0.07 to 0.57, and could be as large as the treatment effect in some of the trials.
Conclusion: This scoping review has shown that two-stage randomized preference trials are not as popular as expected in mental health research. The results indicated that two-stage randomized preference trials in mental health would be beneficial in retaining patients to expand the generalizability of the trial.

Abstract
Background: Recent studies have demonstrated a correlation between intestinal flora and the severity of myocardial infarction as well as post-myocardial infarction repair. However, few studies have investigated whether probiotics reduce mortality and improve cardiovascular outcomes in patients with acute myocardial infarction. In this study, we will conduct a randomized controlled trial (RCT) to evaluate the effect of probiotics on in-hospital mortality and incidence of major adverse cardiovascular events (MACE) in patients with acute myocardial infarction (AMI).
Methods: This is an open-label, randomized, controlled, superiority clinical trial involving 2594 adult patients who diagnosed with acute myocardial infarction. Patients will be randomized to (1)receive bifidobacteria triple viable capsule (Bifidobacterium longum, Lactobacillus acidophilus, and Enterococcus faecalis) 840 mg, twice a day, plus standard treatment strategy during the hospital stay , for a maximum of 30 days, or (2)receive the standard treatment strategy and will not take the bifidobacterium triple live capsule. The primary outcome was in-hospital all-cause mortality. Discussion: The purpose of this clinical trial is to determine whether probiotics can reduce in-hospital mortality and improve prognosis in patients with AMI, and the results will provide evidence for probiotics as a complementary treatment for AMI.

Exploring interdependencies, vulnerabilities, gaps and bridges in care transitions of patients with complex care needs using the Functional Resonance Analysis Method
Authors: Hedqvist Ann-Therese , Praetorius Gesa , Ekstedt Mirjam 
Published: December 2022

Abstract
Background:
Care transitions, such as a patient’s hospital discharge, are complex processes encompassing multiple interactions and requiring coordination between stakeholders. To identify potential improvement measures in care transitions for people with complex care needs, intra- and inter-organisational everyday work needs to be properly understood, including its interdependencies, vulnerabilities and gaps. The aim of this study was to map the coordination of care across healthcare and social care organisations and describe interdependencies and system variability in care transitions.
Methods:
The study was inspired by multi-method research. Data were collected through participant observations, interviews and a document review in a region of southern Sweden. The Functional Resonance Analysis Method was used to model the discharge process and visualise and analyse coordination within and between different organisations and units.
Results:
The results show that hospital discharge is a time-sensitive process with numerous couplings and interdependencies where healthcare professionals are constrained by system design and organisational boundaries. The greatest vulnerability can be found when the patient arrives at home, as maladaptation earlier in the care chain can lead to an accumulation of issues for the municipal personnel in social care working closest to the patient. The possibilities for the personnel to adapt are limited, especially at certain times of day, pushing them to make trade-offs to ensure patient safety. To counteract variability in performance of care, flexibility and adequate resources need to be ensured, to promote the possibility to respond and adjust to uncertainties.
Conclusions:
To achieve safe and secure care transitions from hospital to home, proactive work during discharge planning needs to be facilitated by improving the timing and precision in assessment and planning of patient care. Responding to unexpected events and variations requires successful adaptation and use of allocated resources during the first few days after homecoming, and a system allowing for flexibility to promote safe and personalized care.
Negative Magnetostrictive Paper Formed by Dispersing CoFe 2 O 4 Particles in Cellulose Nanofibers
Authors: Keino Takumi , Rova Lovisa , Gallet--Pandellé Alia , Kurita Hiroki , Narita Fumio 
Published: December 2022

Abstract
Polymers are often combined with magnetostrictive materials to enhance their toughness. This study reports a cellulose nanofiber (CNF)-based composite paper containing dispersed CoFe2O4 particles (CNF–CoFe2O4). Besides imparting magnetization and magnetostriction, the CoFe2O4 particles increase the fracture elongation of the CNF–CoFe2O4 composite paper, although the ultimate tensile strength of the composite paper decreases with increasing CNF content. As strength and toughness are usually inversely proportional, it was inferred that the magnetostrictive CNF–CoFe2O4 composite paper has good toughness.

Abstract
Backgroud: The problem of suicide has become increasingly common in individuals with major depressive disorder (MDD). Transcranial direct current stimulation (tDCS) is an effective treatment for MDD with2 milliamperes (mA) for at least thirty minutes per day for two weeks. This study aims to investigate the efficacy of daily duration-doubled tDCS as an adjunctive intervention for rapidly reducing suicidal ideation and improving depression in MDD patients.
Methods and design: In this double-blind, randomized, sham-controlled study, 76 MDD patients with suicidal ideation are randomly assigned to either active (n=38) or sham (n=38) tDCS group. The anode and cathode are placed over the scalp areas corresponding to left and right dorsolateral prefrontal cortex (DLPFC), respectively, and each stimulation lasts for 60 minutes. The primary outcome is defined as change of Beck Scale for Suicide Ideation (BSI) after 10 sessions. The 17-item Hamilton Depression Rating Scale (HAMD-17), Wisconsin Card Sorting Test (WCST) and Stroop Color-Word Test (SCWT) are utilized to assess depressive symptoms, executive function. Blood biomarkers related to suicidal ideation are collected at baseline and after 10 sessions.
Discussion: This study suggest the adjunctive duration-doubled tDCS might be a novel method to rapidly reduce suicidal ideation and improve depressive symptom. The variation of biomarkers could be potential predictive models of suicide risk.
Trial registration: The trial protocol is registered with ClinicalTrials.gov under protocol registration number NCT05555927. Registered on September 25, 2022.

Abstract
Immune cells employ diverse mechanisms for host defense against pathogens. Macrophages and dendritic cells, in response to toll-like receptor (TLR) activation, assemble aggresome-like induced structures (ALIS). Our group has previously shown that engagement of TLR4 transcriptionally upregulates p62/sequestome1, which in turn assembles ALIS along with LC3 and ubiquitin. We have demonstrated that TLR4 mediated autophagy is, in fact, selective autophagy of ALIS. We hypothesize that TLR-mediated autophagy and ALIS contribute to host-defense. Here we show that ALIS are not only assembled in macrophages upon exposure to several types of bacteria, but these structures are associated with pathogen-containing phagosomes. Importantly, we also present evidence of increased bacterial burden in cells, in which formation of ALIS is prevented with p62 specific siRNA. To gain more insight into the assembly of the constituents of ALIS, we have employed 3D super-resolution structured illumination microscopy (3D SR-SIM) and mass-spectrometric analyses. Ultra-structural analyses by 3D SR-SIM of known constituents of ALIS (namely p62, ubiquitin and LC3) reveals that ALIS are organized structures with distinct patterns of alignment. Furthermore, mass spectrometric analyses of ALIS identified, among others, several proteins of known antimicrobial properties. We have validated mass spectrometry analysis data by testing the association of some of these molecules (Bst2, IFITM2 and IFITM3) with ALIS and the phagocytosed bacteria. Thus, we surmise the enrichment of AMPs in ALIS leads to their delivery to bacteria-containing phagosomes and to restrict the bacteria in host cells. Our findings in this paper support hitherto unknown functions of ALIS in host-defense.
