Objectives To explore the feasibility of shear wave elastography for evaluating sarcopenia. Methods The shear wave velocities (SWV) of the tibialis anterior, medial gastrocnemius, and soleus were measured in 130 subjects in the Second Affiliated Hospital of Fujian Medical University from January 2021 to June 2022. Consistency was evaluated in 20 cases using the intraclass correlation coefficient. According to the 2019 Asian Working Group for Sarcopenia（AWGS） diagnostic criteria, the patients were divided into a healthy and a sarcopenia group. The differences in SWV between the two groups were compared, and their correlation between calf muscles and muscle mass, grip strength, and pace were analyzed. The diagnostic cutoff value of calf muscle SWV for sarcopenia was obtained using receiver operating characteristic (ROC) curves, and the diagnostic efficacy of different ROC curves was compared. Results The SWV inter‐group and intra‐group correlation coefficients of the three lower limbs muscles were all greater than 0.85. Moreover, the corresponding SWV in the sarcopenia group were significantly smaller than those in the healthy control group (P < .05). Further, SWV were positively correlated with the appendicular skeletal muscle mass index (ASMI), grip strength, and gait speed. Finally, the SWV of the anterior tibialis and medial gastrocnemius muscles were 3.02 and 2.26 m/s, respectively, and their diagnostic efficacy for sarcopenia did not differ significantly (Z = 0.190, P = .8497). Conclusion SWE can be used to detect the hardness of the anterior tibialis and medial gastrocnemius, calculate their muscle mass as an effective tool to evaluate sarcopenia.

Background: Postoperative nausea and vomiting (PONV) is one of the common adverse reactions after surgery. Recent randomized controlled trials (RCTs) investigating antiemetic drugs suggest that aprepitant has the strongest antiemetic effect of any single drug. This meta-analysis aimed to explore the efficacy of aprepitant for preventing PONV based on the existing literature. Methods: To identify RCTs investigating the use of aprepitant for PONV prevention, we searched PubMed, Embase, and Cochrane Library databases for articles published prior to March 20, 2022. Seventeen RCTs were identified, with 3299 patients, meeting the inclusion criteria. PONV incidence, complete response, 80 mg aprepitant combined with dexamethasone and ondansetron, vomiting, nausea, and analgesic dose-response were the main outcomes measured. Results: Compared with the control group, PONV incidence was significantly reduced among those receiving aprepitant (odds ratio [OR]: 0.34; 95% confidence interval [CI]: 0.26, 0.44; P < .0001), with a more complete response (OR: 1.35; 95% CI: 1.14, 1.59; P = .0004). Supplementation of 80 mg aprepitant in combination with dexamethasone and ondansetron substantially improved the effects of PONV (OR: 0.36; 95% CI: 0.16, 0.82; P = .01). Further, administration of 80 mg aprepitant was better at preventing vomiting than nausea (OR: 8.6; 95% CI: 3.84, 19. 29; P < .00001). No statistically significant difference between the dose-response of analgesics was identified (mean difference: −1.09; 95% CI: −6.48, 4.30; P = .69). The risk of bias was assessed independently by paired evaluators. Conclusion: Aprepitant effectively reduces the incidence of PONV; however, the effects of postoperative analgesia require further exploration.

Objectives-To assess the efficacy and safety of ultrasound-guided percutaneous ablation (US-PA) for adrenal metastases (AMs) using a meta-analysis.Methods-A systematic search of PubMed, Cochrane, Web of Science, and Embase electronic databases was performed to identify studies on US-PA for AM. Seven studies published between January 2000 and August 2022 were analyzed, which resulted in a sample size of 140 patients. Both random effects and common effects meta-analysis models were used to analyze the following efficacy and safety outcomes: the first and secondary technical success rate, 1-year overall survival rates, 1-year local tumor control rate, incidence rate of intraoperative hypertensive crises, and major complications. The subgroup analysis was performed to explore the origin of heterogeneity.Results-Among 140 patients from 7 studies included in this meta-analysis: 51 (36.43%) underwent radiofrequency ablation (RFA), and 89 (63.57%) underwent microwave ablation (MWA). Pooled data analysis revealed that the first and secondary technical success rates were 85% (95% confidence interval [CI], 73-96) and 99% (95% CI, 96-100), the 1-year overall survival rate was 83% (95% CI, 71-93), the 1-year local tumor control rate was 83% (95% CI, 75-90), and the incidence rate of intraoperative hypertensive crises was 14% (95% CI, 8-20). The overall rate of major complications was 3.6%. In the subgroup analysis, lower heterogeneity was indicated to be associated with mean tumor size and ablation type.Conclusions-This meta-analysis showed that US-PA can be both effective and safe for AM in terms of overall survival, technical success rate, and local control for AM.

Objective Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with the main clinical characteristics of multisystem and multiorgan involvement of the whole body. It is commonly seen in skin mucosa, skeletal muscle, and the respiratory system while rarely involving the spleen. In this case, we present a young female patient with SLE with the symptom of progressing splenic calcification. Methods A 21–year–old female patient was admitted to our hospital in 2012 with complaints of “fever, abdominal pain, diarrhea, and knee pain”, and then was diagnosed with systemic lupus erythematosus combined with lupus nephritis. The first ultrasound examination was normal in 2012. However, when she returned to the hospital in 2016, she was found to have multiple calcifications in her spleen. After discharge, the patient was treated with commonly used immunosuppressive drugs and was followed up regularly for symptoms of multiple calcifications in the spleen. Results Subsequent follow–up over a long period revealed a progressive development of multiple calcifications in the spleen, with a progressive increase in the size and number of calcified foci over time. Conclusion When a patient is found to have diffuse splenic calcification on ultrasound, care should be taken to differentiate SLE with multiple splenic calcifications from sarcoidosis, tuberculosis, brucellosis, and rheumatoid arthritis in conjunction with a medical history and relevant laboratory tests.
