RESUMO
PURPOSE: The aim of this study was to investigate the comprehensive needs of lung cancer patients treated with immune checkpoint inhibitors and to explore the relationships between comprehensive needs and social support and disease perception, moreover, to analyse associated factors of comprehensive needs. METHODS: The study was conducted in a teaching hospital in Jiaxing Province, China. A total of 141 patients with lung cancer completed a battery of self-report questionnaires, including the Comprehensive Needs Assessment Tool in Cancer for Patients (CNAT), Social Supportive Rating Scale (SSRS), Brief Illness Perception Questionnaire (BIPQ), and demographic and clinical characteristics questionnaire. RESULTS: The level of comprehensive needs was highest in the domain "medical demand" (42.17 ± 26.57), and the item with the highest level of comprehensive needs was "I need information about the financial support for my medical expenses" (2.00 ± 1.07). Statistically significant correlations were identified between the comprehensive needs score, social support, and disease perception. The multiple regression analysis showed that immunotherapy course, whether irAEs occur, social support, and disease perception were factors influencing patients' comprehensive needs. CONCLUSIONS: The most prevalent needs in lung cancer patients were found in the "medical needs" domain. Additionally, immunotherapy course, whether irAEs occur, disease perception, and social support were associated with comprehensive needs among lung cancer patients. It is essential to combine the associated factors to accurately evaluate patient needs. We should pay more attention to proposing the comprehensive measures for these patients and providing more individualized supportive care during the lengthy treatment period.

The present study aims to investigate the effect of cathepsin K (CatK) on ischemic angiogenesis in high-fat diet fed mice. The mice were subjected to unilateral hindlimb ischemic surgery, and the ischemic blood flow was measured with a laser Doppler blood flow imager. Immunohistochemical staining was used to observe the quantity of new capillaries in the ischemic lower extremity, and Western blot was used to detect the expression of insulin receptor substrate-1 (IRS-1), p-Akt, Akt and vascular endothelial growth factor (VEGF). Firstly, the effect of high-fat diet on ischemic angiogenesis was observed in wild-type mice, which were randomly divided into control group and high-fat diet group and were fed with normal diet or 60% high-fat diet respectively for 16 weeks. The results showed the body weight and the plasma CatK concentration of the high-fat diet group was significantly increased compared with the control group (P < 0.05), and the blood flow recovery of the high-fat diet group was significantly lower than control group (P < 0.05). Then, wild-type and CatK knock out (CatK-/-) mice were both fed with high-fat diet to further observe the effect and mechanism of CatK on ischemic angiogenesis under high-fat diet. The results showed that the blood flow recovery in the CatK-/- group was significantly greater than the wild-type group, and the number of CD31 positive cells was significantly increased (P < 0.05). At the same time, the protein expression levels of IRS-1, p-Akt and VEGF in the ischemic skeletal muscle were significantly increased in the CatK-/- group compared with the wild-type group (P < 0.05). These results suggest that the deficiency of CatK improves ischemic angiogenesis in high-fat diet fed mice through IRS-1-Akt-VEGF signaling pathway.
