Sunitinib resistance is a major challenge for advanced renal cell carcinoma (RCC). Understanding the underlying mechanisms and developing effective strategies against sunitinib resistance are highly desired in the clinic. Here we identified an lncRNA, named lncARSR (lncRNA Activated in RCC with Sunitinib Resistance), which correlated with clinically poor sunitinib response. lncARSR promoted sunitinib resistance via competitively binding miR-34/miR-449 to facilitate AXL and c-MET expression in RCC cells. Furthermore, bioactive lncARSR could be incorporated into exosomes and transmitted to sensitive cells, thus disseminating sunitinib resistance. Treatment of sunitinib-resistant RCC with locked nucleic acids targeting lncARSR or an AXL/c-MET inhibitor restored sunitinib response. Therefore, lncARSR may serve as a predictor and a potential therapeutic target for sunitinib resistance.

Highlights Among patients with severe or fatal coronavirus disease 2019 (COVID-19), the most prevalent comorbidities were obesity and hypertension, followed by diabetes, cardiovascular disease, respiratory disease, cerebrovascular disease, malignancy, chronic kidney disease, and liver disease. Comorbid respiratory disease was identified as the strongest risk factor for COVID-19 severity, followed by hypertension, cardiovascular disease, chronic kidney disease, cerebrovascular disease, malignancy, diabetes, and obesity. Subgroup analyses were conducted according to severe clinical outcomes and country of residence in the study population. Knowledge of these risk factors could help clinicians better identify and manage the high-risk populations.

To investigate the anxiety/depression of caregivers of stroke patients.This study used a cross-sectional survey design and convenience sampling.Totally, 117 caregivers of stroke patients were enrolled. Data were collected from questionnaires. Hamilton anxiety scale, Hamilton depression scale, and Zarit caregiver burden interview were performed. Multiple linear regression and correlation analysis were used.The anxiety score, depression score and total burden score of 117 stroke caregivers were 16.56 ± 8.02, 18.63 ± 9.39, and 25.88 ± 10.35, respectively. Anxiety symptoms, mild to moderate depressive symptoms, and severe depressive symptoms were found in 43.9%, 26.5%, and 27.4% of the caregivers, respectively. Daily care time and medical payment method were influencing factors for anxiety and depression (P < .05). Both anxiety and depression were positively correlated with total care burden score (P < .01).Anxiety and depression are common in the caregivers of stroke patients and are closely related to care burdens. In this regard, appropriate home care guidance, psychological counseling and social support should be provided to the caregivers to reduce their physical and mental burden.
