To explore in vivo kinematical behavior of the same total knee arthroplasty (TKA) cruciate-retaining (CR) femoral design with either medial-congruent (MC) or ultra-congruent (UC) inlay using model-based dynamic radiostereometric analysis (RSA). The hypothesis was that there would be comparable kinematics between the two groups.

A cohort of 16 randomly selected patients (8 MC Persona Zimmer, 8 UC Persona Zimmer) was evaluated through dynamic radiostereometric analysis (RSA) at a minimum of 9months after TKA, during the execution of a sit-to-stand. The antero-posterior (AP) translation of the femoral component and the AP translation of the low point of medial and lateral femoral compartments were compared through Student's t test (p < 0.05).

Both groups showed a medial pivot behavior, with a significantly greater anterior translation of the Low Point of the lateral compartment with respect to the medial compartment (MC medial range 2.4 ± 2.4mm; MC lateral range 7.7 ± 3.0mm; p < 0.001 - UC medial range 3.3 ± 3.3mm; UC lateral range 8.0 ± 3.2mm; p < 0.001). A statistically significant greater degree of flexion was clinically recorded at follow-up visit in the MC group respect to the UC group (126° vs 101°-p = 0.003).

The present study did not show difference in the medial pivot behavior between ultra-congruent and medial-congruent total knee arthroplasty when implanted with mechanical alignment; however, the MC group demonstrated a greater degree of flexion. The MC design examined is a valid alternative to the UC design, allowing to achieve a screw-home movement restoration combined with a high flexion.

The Phase 3 DISCOVER-1 study of guselkumab is the first randomized controlled trial to use Patient-Reported Outcomes Measurement Information System (PROMIS) measures to assess the effects of treatment on general health outcomes in patients with psoriatic arthritis (PsA).

Patients (N = 381) with active PsA were randomized 111 to guselkumab 100 mg every 4 weeks (Q4W); guselkumab 100 mg at Week 0, Week 4, then every 8 weeks (Q8W); or placebo with Week 24 crossover to guselkumab Q4W. The PROMIS-29 Profile contains four items for each of sevendomains (anxiety, depression, fatigue, pain interference, physical function, sleep disturbance, and social participation) and one pain-intensity item. Raw domain scores are converted to standardized T-scores, with norms based on a US general population mean of 50 (1 standard deviation (SD) = 10). T-score changes of ≥5 are considered clinically meaningful. Least-squares mean PROMIS-29 T-score changes from baseline to Week 24 and Week 52 were summarized for the guselkumab aysical function, sleep, and social participation at Week24 versus placebo (all nominal p ≤ 0.05).

In patients with active PsA, guselkumab treatment provided clinically meaningful reductions in fatigue and pain and improvement in physical function and social participation, as measured by the PROMIS-29 Profile. These improvements were maintained through 1 year.

GOV Registration number, NCT03162796; Submission date 19 May 2017.Our recent study has shown that TRIM36, a member of tripartite motif-containing (TRIM) family proteins and tumor suppressor and β-catenin may serve as a prognostic biomarker for esophageal squamous cell carcinoma (ESCC). Here, we sought to examine functional roles of TRIM36 and β-catenin in ESCC cells. TRIM36 was overexpressed or silenced by lentivirus transduction. Cell proliferation was examined by Cell Counting Kit (CCK)-8 assay, while cell cycle distribution and cell apoptosis was assessed via flow cytometry analysis. Xenograft mouse model was applied for in vivo analysis. Overexpression of TRIM36 inhibited cell proliferation in human ESCC cells, and silencing of TRIM36 led to opposite effects. We also found that ectopic expression of TRIM36 enhanced the ratio of G0/G1 phase cells and induced apoptosis in ESCC cells. Our data further revealed that TRIM36 stimulated the ubiquitination of β-catenin, and in turn, its inactivation. Finally, we confirmed these in vitro results in a xenograft mouse model and clinical specimens post-operatively obtained from patients of ESCC. In summary, these data support that TRIM36 can effectively inhibit tumorigenesis of ESCC by repressing Wnt/β-catenin signaling pathway, which suggest that selectively repressing this signaling pathway in ESCC may lead to development of a novel therapeutic approach for controlling this disease.Failure to consider the principles of equity, diversity and inclusion in biomedical and human behaviour research harms patients, trainees and scientists. On the basis of experience and evidence, we make actionable, specific recommendations on how equity, diversity and inclusion can be considered at each step of a research project.
We aimed to assess the efficacy of intrapyloric botulinum toxin A injection (IPBTI) in children with and without gastroparesis and to perform a meta-analysis and review of the literature.

We retrospectively searched our electronic health records to identify children (aged <18 years) who underwent an esophagogastroduodenoscopy with IPBTI between 2007 and 2018 for persistent upper gastrointestinal tract symptoms. We included children with and without gastroparesis and excluded children with a history of gastrointestinal surgery, gastrointestinal obstruction, or mucosal disease that could explain their symptoms. A meta-analysis including our study findings was performed.

We identified 20 children (mean [standard deviation] age, 9.7 [5.8] years; 14 [70%] girls) with upper gastrointestinal symptoms who underwent IPBTI at our institution during the study period. Of the 20 children, 17 (85%) underwent gastric emptying scintigraphy, only nine (53%) of whom had gastroparesis. Response to IPBTI was reported in ten children (50%). Response to IPBTI did not differ by the presence of gastroparesis in included children (p = 0.64). Repeated IPBTI was performed in four children who had a response to the first injection; all four reported no benefit from the second IPBTI. There were no reported complications of IPBTI in our cohort. The meta-analysis indicated that 68% (95% confidence interval 59-78) of patients had a response to IPBTI, regardless of the presence of gastroparesis; 66% (95% confidence interval 53-78) of patients who had gastroparesis had a response to IPBTI.

Intrapyloric botulinum toxin A injection is safe in children and can offer transient relief for patients with refractory upper gastrointestinal symptoms with and without gastroparesis.

Mounting evidence has shown that posttranslational protein modifications play vital roles in the DDR. In this study, we showed that deubiquitinase OTUD6A is involved in the DDR and is important for maintaining genomic stability. Mechanistically, in response to DNA damage, the abundance of OTUD6A was increased; meanwhile, PP2A interacted with OTUD6A and dephosphorylated OTUD6A at sites S70/71/74, which promoted nuclear localization of OTUD6A. Subsequently, OTUD6A was recruited to the damage site, where it interacted with TopBP1 and blocked the interaction between TopBP1 and its ubiquitin E3 ligase UBR5, decreasing K48-linked polyubiquitination and increasing the stability of TopBP1. OTUD6A depletion impaired CHK1 S345 phosphorylation and blocked cell cycle progression under DNA replication stress. Consistently, knockout of OTUD6A rendered mice hypersensitive to irradiation, shortened survival, and inhibited tumor growth by regulating TopBP1 in xenografted nude mice. Moreover, OTUD6A is expressed at high levels in breast cancer, and OTUD6A overexpression promotes cell proliferation, migration and invasion, indicating that dysregulation of OTUD6A expression contributes to genomic instability and is associated with tumor development. In summary, this study demonstrates that OTUD6A plays a critical role in promoting tumor cell resistance to chemoradiotherapy by deubiquitinating and stabilizing TopBP1.The global distribution of laboratory mouse strains is valued for ensuring the continuity, validity and accessibility of model organisms. Mouse strains are therefore assumed mobile and able to travel. We draw on the concept of 'animal mobilities' (Hodgetts and Lorimer 2019) to explain how attending to laboratory mice as living animal, commodity and scientific tool is shaping how they are transported through contemporary scientific infrastructures and communities. Our paper is framed around exploring how animal strains travel, rather than animals, as we show that it is only through understanding strain mobility that we can explain how and why live animal movement can be replaced by germinal products. The research is based on qualitative fieldwork in 2018 and 2019 that included 2 weeks ethnography and interviews with key informants involved in the movement of laboratory animals. The empirical analysis discusses practices that relate to managing biosecurity and animal welfare concerns when moving laboratory animal strains. In closing we reflect more broadly on the contemporary 'ethico-onto-epistemological' (Barad, 2014) entanglement that shapes who or what travels to support laboratory science data-making practices, and the intensity of care 'tinkering' practices (Mol and Law 2010) that facilitate the movement. We explain how a laboratory animal strain exceeds its value solely as a mobile and thus exchangeable commodity, illustrated in how values that relate to animal sentience and infection-risk supports its material transformation. Consequently, it is becoming increasingly common for non-sentient germinal products - embryos and gametes - to replace live sentient animals when being moved.Leaf microbiomes play crucial roles in plant health, making it important to understand the origins and functional relevance of their diversity. High strain-level leaf bacterial genetic diversity is known to be relevant for interactions with hosts, but little is known about its relevance for interactions with the multitude of diverse co-colonizing microorganisms. In leaves, nutrients like amino acids are major regulators of microbial growth and activity. Using metabolomics of leaf apoplast fluid, we found that different species of the plant genus Flaveria considerably differ in the concentrations of high-cost amino acids. We investigated how these differences affect bacterial community diversity and assembly by enriching leaf bacteria in vitro with only sucrose or sucrose + amino acids as possible carbon sources. Enrichments from F. robusta were dominated by Pantoea sp. and Pseudomonas sp., regardless of carbon source. The latter was unable to grow on sucrose alone but persisted in the sucrose-only enrichment thanks to exchange of diverse metabolites from Pantoea sp. Individual Pseudomonas strains in the enrichments had high genetic similarity but still displayed clear niche partitioning, enabling distinct strains to cross-feed in parallel. Pantoea strains were also closely related, but individuals enriched from F. trinervia fed Pseudomonas more poorly than those from F. robusta. This can be explained in part by the plant environment, since some cross-feeding interactions were selected for, when experimentally evolved in a poor (sucrose-only) environment but selected against in a rich (sucrose + amino acids) one. selleck chemicals Together, our work shows that leaf bacterial diversity is functionally relevant in cross-feeding interactions and strongly suggests that the leaf resource environment can shape these interactions and thereby indirectly drive bacterial diversity.
