Idiopathic tenosynovitis of the wrist with multiple rice bodies: A case report and review of literature

BACKGROUND Multiple rice bodies in the wrist is a rare disorder that requires surgery,and there are still many uncertainties regarding its diagnosis and treatment.CASE SUMMARY We described a rare case of chronic idiopathic tenosynovitis with rice bodies of the wrist in a 71-year-old man and reviewed similar topics in the literature.A total of 43 articles and 61 cases were included in the literature review.Our case had a usual presentation:it was similar to those in the literature.The affected population was mainly older adults,with an average age of 59.43(range,3 to 90)years.The male-to-female ratio was 1.54:1(37/24).Most of them showed limited swelling and pain,only 23.0%had carpal tunnel symptoms,and the average disease duration was 18.03(0.5-60)mo.Wrist flexor tendon sheath involvement was the most common(95.1%,58/61),and only 3 cases had extensor tendon sheath involvement.The main causes were tuberculosis(34.4%,21/61),nontuberculous mycobacteria(24.6%,15/61),idiopathic tenosynovitis(31.1%,19/61),and others(9.84%,6/61).There were 10 patients with recurrences;in 6 of them,were due to non-tuberculous mycobacterial infections.CONCLUSION We reported a case of wrist idiopathic tenosynovitis with rice body formation,and established a clinical management algorithm for wrist tenosynovitis with rice bodies,which can provide some reference for our clinical diagnosis and treatment.The symptoms of rice-body bursitis of the wrist are insidious,nonspecific,and difficult to identify.The aetiology is mainly idiopathic tenosynovitis and mycobacterial(tuberculosis or non-tuberculous)infections;the latter are difficult to treat and require long-duration systemic combination antibiotic therapies.Therefore,before a diagnosis of idiopathic tenosynovitis is made,we must exclude other causes,especially mycobacterial infections.

CEPC Technical Design Report

The Circular Electron Positron Collider(CEPC)is a large scientific project initiated and hosted by China,fostered through extensive collaboration with international partners.The complex comprises four accelerators:a 30 GeV Linac,a 1.1 GeV Damping Ring,a Booster capable of achieving energies up to 180 GeV,and a Collider operating at varying energy modes(Z,W,H,and tt).The Linac and Damping Ring are situated on the surface,while the subterranean Booster and Collider are housed in a 100 km circumference underground tunnel,strategically accommodating future expansion with provisions for a potential Super Proton Proton Collider(SPPC).The CEPC primarily serves as a Higgs factory.In its baseline design with synchrotron radiation(SR)power of 30 MW per beam,it can achieve a luminosity of 5×10^(34)cm^(-2)s^(-1)per interaction point(IP),resulting in an integrated luminosity of 13 ab^(-1)for two IPs over a decade,producing 2.6 million Higgs bosons.Increasing the SR power to 50 MW per beam expands the CEPC's capability to generate 4.3 million Higgs bosons,facilitating precise measurements of Higgs coupling at sub-percent levels,exceeding the precision expected from the HL-LHC by an order of magnitude.This Technical Design Report(TDR)follows the Preliminary Conceptual Design Report(Pre-CDR,2015)and the Conceptual Design Report(CDR,2018),comprehensively detailing the machine's layout,performance metrics,physical design and analysis,technical systems design,R&D and prototyping efforts,and associated civil engineering aspects.Additionally,it includes a cost estimate and a preliminary construction timeline,establishing a framework for forthcoming engineering design phase and site selection procedures.Construction is anticipated to begin around 2027-2028,pending government approval,with an estimated duration of 8 years.The commencement of experiments and data collection could potentially be initiated in the mid-2030s.

Upcycling electroplating sludge into bioengineering-enabled highly stable dual-site Fe-Ni_(2)P@C electrocatalysts for efficient oxygen evolution

The advancement of bimetallic catalysts holds significant promise for the innovation of oxygen evolution reaction(OER)catalysts.Drawing from adsorbate evolution mechanism(AEM)and lattice oxygen oxidation mechanism(LOM),the incorporation of dual active sites has the potential to foster novel OER pathways,such as the coupled oxygen evolution mechanism(COM),which can surpass the limitations of OER and elevate catalytic performance.In this study,uniformly distributed Fe/Ni dual-site Fe-Ni_(2)P@C electrocatalysts are crafted by upcycling metals in electroplating sludge via an eco-friendly and sustainable microbial engineering technique.Our findings indicate that a substantial number of defects emerge at the Ni2P crystal during the OER process,laying the groundwork for lattice oxygen involvement.Moreover,the displacement of Ni/Fe in the crystal lattice intensifies the asymmetry of the electronic structure at the metal active sites,facilitating the deprotonation process.This research introduces an innovative paradigm for the synthesis of effective and robust transition metal-based OER catalysts,with implications for sustainable energy generation technologies.

Correlation between longitudinal crack occurrence and mold heat transfer in continuous casting based on process data mining

The correlation between the longitudinal crack occurrence and integrated heat transfer of the mold with data mining methods was investigated.Firstly,three kinds of support vector machine models based on principal component analysis with different input features were established to explore the effect of integrated heat transfer on the accuracy of the prediction model for the longitudinal crack.The results show that the accuracy was improved while features including mean and standard deviation of integrated heat transfer were added.Then,the difference in integrated heat transfer between defect and normal samples under the same process parameters was quantitatively compared.Compared with normal samples,the temperature difference of cooling water for defect samples decreased by 0.65%,and the temperature difference fluctuation increased by 31.1%.Finally,the literature data were used to provide support for the quantitative correlation according to defect formation mechanism.A new criterion for the prediction of longitudinal crack and a discovering method for correlation between product quality and process parameters in the manufacturing industry have been provided.
