BackgroundHospitalized patients with cirrhosis are prone to debilitating health conditions and fluid fluctuations, posing barriers to accurately obtain anthropometric measures and physical examinations as surrogates for muscle mass within the Global Leadership Initiative on Malnutrition (GLIM). We hypothesize the handgrip strength (HGS) would serve as a substitutive metric, by comparing the diagnostic consistency and prognostic accuracy with computed tomography–demarcated skeletal muscle index (SMI)–defined malnutrition according to the GLIM criteria.MethodsPatients with cirrhosis underwent a two‐step approach involving nutrition risk screening and those fulfilling GLIM consensus were further diagnosed. The evaluation of muscle mass as one constituent contained in the GLIM criteria was conducted by SMI and HGS, respectively. Consistency test, Kaplan‐Meier curve, and multivariate Cox regression were used to assess the performance of GLIM‐SMI and GLIM‐HGS.ResultsAmong 184 hospitalized patients with cirrhosis, 63 (34.2%) and 78 (42.4%) were diagnosed with malnutrition following GLIM‐SMI and GLIM‐HGS criteria, respectively. Considering the GLIM‐SMI a gold standard, GLIM‐HGS had a sensitivity of 87.3% and a specificity of 81.0%. GLIM‐HGS criteria denoted good agreement (κ value = 0.858, P < 0.001) as compared with GLIM‐SMI. Both criteria were independently associated with 1‐year all‐cause mortality, whereas GLIM‐SMI showed slightly higher hazard ratios. Moreover, HGS positively correlated with SMI in the population alongside more pronounced correlation among patients at nutrition risk.ConclusionHGS may serve as a substitutive metric of muscle mass contained in the GLIM criteria to diagnose malnutrition and predict long‐term mortality among patients with cirrhosis.

With the official proposal of carbon peaking and carbon neutrality goals, new energy vehicles are developing rapidly in my country. Among them, hydrogen fuel cell vehicles are considered as the most promising new energy vehicles because of their good endurance and the ability to produce hydrogen by electrolysis of water using renewable energy. This paper presents a hydrogen fuel cell vehicle based on solar energy hydrogen production technology. In addition to hydrogenation through hydrogenation stations, the car can also use solar power to achieve electrolytic water hydrogen production, further realizing the goal of energy conservation and environmental protection.

With the continuous development of society, indoor monitoring is increasingly widely used. At present, video surveillance mainly uses artificial real-time monitoring or post-monitoring to check indoor conditions and people. This paper describes the components and working principle of YOLOv5, and uses YOLOv5 algorithm to conduct network simulation and training for indoor common targets. Through the indoor photography head to collect the scene, using YOLOv5 algorithm to process the original photos, when there is an abnormal person in the image, the system will issue an alarm to remind the owner to deal with it in time. The experiment shows that the system can respond the indoor situation economically, quickly and effectively and meet the demand of indoor anti-theft.
