Thick electrode with high-areal-capacity is a practical and promising strategy to increase the energy density of batteries, but development toward thick electrode is limited by the electrochemical performance, mechanical properties, and manufacturing approaches. In this work, we overcome these limitations and report an ultrathick electrode structure, called fiberaligned thick or FAT electrode, which offers a novel electrode design and a scalable manufacturing strategy for high-areal-capacity battery electrodes. The FAT electrode uses aligned carbon fibers to construct a through-thickness fiber-aligned electrode structure with features of high electrode material loading, low tortuosity, high electrical and thermal conductivity, and good compression property. The low tortuosity of FAT electrode enables fast electrolyte infusion and rapid electron/ion transport, exhibiting a higher capacity retention and lower charge transfer resistance than conventional slurry-casted thick electrode design.
Enhanced recovery after surgery (ERAS) is acknowledged to reduce perioperative stress in several surgical diseases. Here, we investigated whether modified ERAS is associated with beneficial effects in the setting of emergency colorectal surgery.We retrospectively evaluated the medical records of 839 consecutive patients with obstructive colorectal cancer undergoing surgical intervention at 4 institutes. Among them, 356 cases were managed with a multidisciplinary team approach to care (modified ERAS protocols), and the remaining 483 cases were treated based on traditional protocols. According to modified ERAS or traditional care, propensity score (PS) matching was performed to adjust biases in patient selection. The primary outcome was gastrointestinal function recovery. Secondary outcomes included postoperative complications and length of hospital stay.Modified ERAS was associated with postoperative gastrointestinal function recovery, including time to first flatus (P = .002), first defecation (P = .008), and prolonged ileus (P = .016). According to the Clavien–Dindo classification, fewer total episodes of grade II or higher postoperative complications were observed in patients cared for with modified ERAS than in patients with traditional care (P = .002). Median (interquartile range) postoperative hospital stay in the modified ERAS group was 6 (3–22) days versus 9 (7–27) days in the traditional care group (P < .001). Furthermore, the interval from operation to postoperative chemotherapy (d) was significantly shorter in the modified ERAS group (35.6 ± 11.5 vs 47.6 ± 23.8, P < .001).The modified ERAS was safe and associated with clinical benefits, including fast recovery of bowel function, reduced postoperative complications, and shorter hospital stay for patients with obstructive colorectal cancer.
Aim: To investigate the incidence of pancreatic cancer-related depression and the relationship between symptoms of depression and the quality of life (QoL) of patients. Methods: 262 inpatients with cancer of the digestive system (pancreatic cancer, liver cancer, esophageal cancer, gastric cancer, and colorectal cancer) from four Guangzhou hospitals were enrolled into the study between June 2007 and June 2009. The Hamilton Rating Scale for Depression-24 questionnaire was used to assess the degree of depression. QoL of all patients was evaluated by EORTC QLQ-C30. Additionally, EORTC QLQ-PAN-26 was used for patients with pancreatic cancer. Results: The incidence of depression among pancreatic cancer patients was significantly higher than among other digestive cancers. More pancreatic cancer patients suffered severe depression than those with liver cancer and gastric cancer. Compared with other groups with depression, QoL of pancreatic cancer patients in each functioning scale was significantly worse, while the symptoms of fatigue and pain were significantly severe. QoL of pancreatic cancer patients with depression in role, emotional, and social functioning were sharply poorer than those without depression. The symptoms of fatigue, pain and appetite loss in cancer patients with depression were significantly more frequent than those without depression. Conclusion: Compared with other cancers of the digestive system, depressive symptoms are common psychological disturbances in pancreatic cancer patients. Moreover, depression significantly lowers QoL in pancreatic cancer patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
