Abstract

Background: We aimed to investigate the association between protein intake and quadriceps quantity and quality on the paretic and non-paretic sides during rehabilitation in people with subacute stroke. Method: Eighty-six people with stroke were recruited from a rehabilitation ward. We measured quadriceps muscle quantity and quality on the paretic and non-paretic sides using ultrasonography at admission and after 4 weeks. Protein intake was assessed 2 or 3 weeks after admission, and participants were classified into two groups: adequate and inadequate protein intake groups. Analysis of covariance was used to determine the effects of protein intake on quadriceps muscle quantity and quality. Results: The mean age (standard deviation), median interval between stroke onset and admission (interquartile range) and male proportion of the study participants were 67.6 (13.5) years, 22.5 (16.8–31.3) days, and 54.7%, respectively. The adequate protein intake group showed significantly greater improvements in paretic-side quadriceps thickness than the inadequate group (group-by-time interaction, F = 8.771, P = 0.004). In contrast, no significant interactions were observed in quadriceps thickness on the non-paretic side (F = 2.383, P = 0.127) and quadriceps echo intensity on both sides (paretic-side: F = 0.020, P = 0.887, non-paretic side: F = 0.181, P = 0.672). Conclusions: Adequate protein intake may be useful for improving quadriceps quantity on the paretic side in people with subacute stroke undergoing rehabilitation. However, quadriceps quantity on the non-paretic side and quadriceps quality on both sides were not significantly associated with adequate protein intake. We investigated the association between protein intake and quadriceps quantity and quality on the paretic and non-paretic sides during rehabilitation in people with subacute stroke. The adequate protein intake group showed significantly greater improvements in paretic-side quadriceps muscle quantity. Conversely, no differences in quadriceps quantity on the non-paretic side and quadriceps quality on both sides were observed between the adequate and inadequate protein intake groups.

Abstract

Background/Objectives: Our aim was to compare the complication rates of different embolization materials (absolute ethanol and gelatin sponges) used for combined transarterial embolization (TAE) and to investigate the impact of tumor size on operative time and cryoneedle use during percutaneous cryoablation (PCA). Methods: We treated 27 patients (9 women and 18 men; mean age, 74 years) with 28 early-stage (T1a) renal cell carcinoma (RCC) lesions using combined TAE and PCA between September 2018 and January 2021. During TAE, 15 lesions in 14 patients were embolized using mixed absolute ethanol and iodized oil. The remaining 13 lesions (in 13 patients) were embolized using a gelatin sponge followed by iodized oil. The PCA was performed within 3 to 21 days of the TAE. We compared complications between the TAE subgroups (i.e., absolute ethanol and gelatin sponge) and assessed potential correlations between tumor size and the operative time of the PCA. Results: All patients were successfully treated by combined TAE-PCA. Local control was achieved for all patients (monitoring period, 1–48 months; median, 28 months). Although the effect of TAE did not differ between subgroups, a significantly higher number of patients in the absolute ethanol group experienced intraprocedural pain than in the gelatin sponge group (p < 0.05). The operative time of the PCA was significantly correlated with the size of the RCC lesion (p < 0.01). The number of cryoneedles used for the PCA was also correlated with the size of the RCC lesion (p < 0.0001). Conclusions: For TAE prior to PCA for early-stage RCC, gelatin sponges can replace absolute ethanol to reduce intraprocedural pain. Tumor size correlates with operative time and the number of cryoneedles needed for PCA, which suggests the total medical cost for PCA therefore varies based on the tumor's size.

Abstract

Background/Objectives: The usefulness of dual-energy computed tomography (DECT) for low absorption in the parenchymal phase and contrast effects in the delayed phase for pancreatic cancer is not clear. Therefore, the diagnostic capability of low-KeV images obtained using DECT for pancreatic cancer in the pancreatic parenchymal and delayed phases was evaluated quantitatively and qualitatively. Methods: Twenty-five patients with pancreatic cancer who underwent contrast-enhanced DECT were included. A total of 50 and 70 KeV CT images, classified as low-keV and conventional CT-equivalent images, were produced, respectively. The tumor-to-pancreas contrast (Hounsfield units [HU]) in the pancreatic parenchymal and delayed phases was calculated by subtracting the CT value of the pancreatic tumor from that of normal parenchyma. Results: The median tumor-to-pancreas contrast on 50 KeV CT in the pancreatic parenchymal phase (133 HU) was higher than that on conventional CT (68 HU) (p < 0.001). The median tumor-to-pancreas contrast in the delayed phase was −28 HU for 50 KeV CT and −9 HU for conventional CT (p = 0.545). For tumors < 20 mm, the tumor-to-pancreas contrast of 50 KeV CT (−39 HU) had a significantly clearer contrast effect than that of conventional CT (−16.5 HU), even in the delayed phase (p = 0.034). Conclusions: These 50 KeV CT images may clarify the low-absorption areas of pancreatic cancer in the pancreatic parenchymal phase. A good contrast effect was observed in small pancreatic cancers on 50 KeV delayed-phase images, suggesting that DECT is useful for the visualization of early pancreatic cancer with a small tumor diameter.
