Background and objectives Previous reports on the outbreak of coronavirus disease 2019 were on the basis of data from the general population. Our study aimed to investigate the clinical features of patients on maintenance hemodialysis. Design, setting, participants, & measurements In this retrospective, single-center study, we included 49 hospitalized patients on maintenance hemodialysis and 52 hospitalized patients without kidney failure (controls) with confirmed coronavirus disease 2019 at Tongren Hospital of Wuhan University from January 30, 2020 to March 10, 2020. Demographic, clinical, laboratory, and radiologic characteristics and treatment and outcomes data were analyzed. The final date of follow-up was March 19, 2020. Results The median age of 101 patients was 62 years (interquartile range, 49-72). All patients were local residents of Wuhan. In terms of common symptoms, there were differences between patients on hemodialysis and controls (fatigue [59% versus 83%], dry cough [49% versus 71%], and fever [47% versus 90%]). Lymphocyte counts were decreased (0.83109/L [patients on hemodialysis] versus 0.93109/L [controls], P=0.02). Comparing patients on hemodialysis with controls, creatine kinase-muscle and brain type, myoglobin, hypersensitive troponin I, B-type natriuretic peptide, and procalcitonin were increased, and the percentage of abnormalities in bilateral lung was higher in computed tomographic scan (82% versus 69%, P=0.15) and unilateral lung was lower (10% versus 27%, P=0.03). Common complications including shock, acute respiratory distress syndrome, arrhythmia, and acute cardiac injury in patients on hemodialysis were significantly higher. Compared with controls, more patients on hemodialysis received noninvasive ventilation (25% versus 6%, P=0.008). As of March 19, 2020, three patients on hemodialysis (6%) were transferred to the intensive care unit and received invasive ventilation. Seven patients on hemodialysis (14%) had died. Conclusions The main symptoms of coronavirus disease 2019 pneumonia, including fever and cough, were less common in patients on hemodialysis. Patients on hemodialysis with coronavirus disease 2019 were at higher risk of death.

Selective laser welding in liquid: A strategy for preparation of high-antibacterial activity nanozyme against Staphylococcus aureus

Yang Li, Shuhan Li, Ran Zhou, Guqiang Li, Xiangyou Li

Summary: In this study, a high-antibacterial activity SOD-like nanozyme based on hybrid Ag/CeO2 nanocomposite was prepared using selective laser welding in liquid. The prepared nanozyme exhibited a high antimicrobial effect against Staphylococcus aureus under visible light illumination, with a sterilization rate as high as 82.4%, which was significantly higher than pure Ag and pure CeO2. The enhanced antibacterial activity was attributed to the anchoring of Ag nanospheres on the surface of CeO2 nanosheets, promoting visible light harvesting and generating abundant reactive oxygen species.

Summary: This paper investigates the application of LPBF/DED hybrid laser additive manufacturing technology in the manufacturing of aluminum alloy components. The results show that there are no obvious defects at the LPBF/DED interface, but the microstructure around the interface changes significantly. The LPBF zone has higher microhardness and tensile strength, while the DED zone has better elongation. The tensile strength of the LPBF/DED interface is not lower than the DED zone. The findings have important implications for understanding and applying LPBF/DED hybrid laser additive manufacturing technology.

Summary: Long-term sequelae clustering phenotypes play a crucial role in providing precise health care management for COVID-19 survivors. In this study, we examined 1000 survivors in China 20 months after their COVID-19 diagnosis. The results showed that generalized symptoms were most common, followed by mental, cardiopulmonary, neurological, and digestive symptoms. Four clusters were identified based on symptom patterns, ranging from no or mild symptoms to severe impairment. Factors such as physical comorbidities, history of mental disorders, longer hospitalization periods, and severe acute illness were associated with more severe symptoms. This study highlights the importance of identifying and addressing specific sequelae clusters in COVID-19 survivors for targeted recovery interventions.

A new understanding of laser-arc plasma interaction of hybrid welding based on arc layering behaviors

Xin Li, Zhenlin Hu, Jian Lai, Wenzhong Gao, Mengcheng Gong, Chen Zhang, Ming Gao

Summary: Current studies of laser-arc plasma interaction have overlooked the layering behaviors of the metal inert gas (MIG) arc, leading to a lack of understanding of laser-MIG hybrid welding. This study investigated the effects of laser power on the double-layer MIG, which consists of an outer plasma layer and a core metal vapor layer. The results showed that the emergence of arc layering was delayed by laser-arc plasma interaction, with the outer layer expanding and the core layer constricting due to laser power. These findings provide a more reasonable explanation for weld shape variations and highlight the importance of considering arc layering in laser-arc hybrid processes.

Ke Liu, Zhiyang Tang, Wen Zhang, Xiangyou Li

Summary: Chlorinated volatile organic compounds (Cl-VOCs) are priority pollutants in most countries due to their severe toxicity and low biodegradability. Traditional monitoring methods with low temporal resolutions are insufficient for intermittent air pollution. Laser-induced breakdown spectroscopy (LIBS) has been considered a viable technology for Cl-VOCs analysis, but faces challenges due to the absorption of Cl atomic lines by oxygen in air. However, a novel approach using LIBS assisted with molecular spectra shows promise for sensitive and real-time analysis of Cl-VOCs.
