RESUMO

OBJECTIVE: Cancer cachexia constitutes a poor prognostic factor in patients with lung cancer. However, the factors associated with cancer cachexia remain unclear. This study aimed to identify factors that influence cancer cachexia in patients with lung cancer. METHODS: In this retrospective observational study conducted at the Kansai Medical University, 76 patients with lung cancer were evaluated for physical function, nutritional status (Mini Nutritional Assessment-Short Form) and physical activity (International Physical Activity Questionnaire-Short Form) at the first visit to the rehabilitation outpatient clinic. The patients were divided into cachexia and noncachexia groups. The log-rank tests and Cox proportional hazards model were used to investigate the relationship between cachexia and prognosis. To examine the factors that influence cachexia, multivariate regression analysis with significant (P < 0.05) variables in the univariate logistic regression analysis was performed. Spearman's correlation analysis was performed to investigate the association between International Physical Activity Questionnaire-Short Form and performance status. RESULTS: Overall, 42 patients (55.2%) had cachexia associated with survival time since their first visit to the outpatient rehabilitation clinic, even after confounders adjustment (hazard ratio: 3.24, 95% confidence interval: 1.12-9.45, P = 0.031). In the multivariate analysis, Mini Nutritional Assessment-Short Form (odds ratio: 20.34, 95% confidence interval: 4.18-99.02, P < 0.001) and International Physical Activity Questionnaire-Short Form (odds ratio: 4.63, 95% confidence interval: 1.20-17.89, P = 0.026) were identified as independent factors for cachexia. There was no correlation between International Physical Activity Questionnaire-Short Form and performance status (r = 0.155, P = 0.181). CONCLUSION: Malnutrition and low physical activity were associated with cachexia in patients with lung cancer. The International Physical Activity Questionnaire-Short Form may be a useful indicator of physical activity in cachexia. Regularly assessing these factors and identifying suitable interventions for cachexia remain challenges to be addressed in the future.

RESUMO

Emergency surgery was performed to treat acute lower limb ischemia caused by heart thromboembolism and concomitant popliteal artery aneurysm. Using a near-infrared spectroscopy oximeter, regional tissue oxygen saturation (rSO2) was monitored to assess the tissue perfusion pre-, intra-, and postoperatively. rSO2 values did not increase sufficiently following thromboembolectomy of the superficial femoral artery, but they dramatically recovered after additional popliteal-anterior tibial bypass surgery. The affected limb was successfully salvaged. rSO2 monitoring was easily measured intraoperatively, which might be beneficial in evaluating tissue perfusion in patients with acute limb ischemia.

RESUMO

OBJECTIVE: To predict sac enlargement with type II endoleak (ELII) before endovascular aneurysm repair (EVAR) using four dimensional flow sensitive magnetic resonance imaging (4D flow MRI). METHODS: A single centre retrospective analysis of prospectively collected data was conducted. Patients with an abdominal aortic aneurysm (AAA) who underwent EVAR between 2013 and 2019 were included. Aortic branches occluded pre-EVAR, and patients with endoleaks other than ELII were excluded. The aortic branch diameter, peak flow velocity (PFVe), and amplitude of the dynamics of flow volume (AFV) were measured in each aortic branch pre-EVAR. Total flow volume per minute (TFV/min), defined as the sum of AFV/min, was calculated in each case. According to computed tomography findings one year post-EVAR, the aortic branches and patients were divided into patent vessel and occluded vessel groups and sac expanding and non-expanding groups. PFVe, AFV/min, and TFV/min were analysed via receiver operating characteristic curve analysis. RESULTS: The patent aortic branches pre-EVAR (69 inferior mesenteric arteries [IMAs]; 249 lumbar arteries [LAs]) of 100 patients were included. Patent IMAs (n = 14) and occluded IMAs (n = 55), patent LAs (n = 23) and occluded LAs (n = 226), and expanding (n = 9) and non-expanding (n = 91) groups were compared, respectively. No statistically significant difference was observed in branch diameters (IMA; patent, 2.5 ± 0.8 mm, occluded, 2.5 ± 0.8 mm, p < .78 and LA; patent, 1.5 ± 0.3 mm, occluded, 1.5 ± 0.4 mm, p < .35). PFVe (IMA; patent, 262.6 mm2/sec, occluded, 183.4 mm2/sec and LA; patent, 142.6 mm2/sec, occluded, 47.7 mm2/sec) and AFV/min (IMA; patent, 8.4 mL, occluded, 5.2 mL and LA; patent, 4.2 mL, occluded, 1.4 mL) were higher in the patent vessel group (p < .050). TFV/min was statistically significantly higher in the expanding group (24.1 mL/min) than in the non-expanding group (7.0 mL/min) (p < .010). CONCLUSION: Pre-EVAR haemodynamic analyses using 4D flow MRI were useful to detect aortic branches responsible for ELII and to predict AAA cases with sac enlargement. This analysis suggests a new strategy for pre-EVAR aortic branch embolisation.
