Both Diet and Exercise Are Necessary for Obese CKD Patients: A Pilot Prospective Randomized Controlled Study

Aim: This study aimed to examine the effects of exercise training on kidney function and nutrition status in obese Chronic Kidney Disease (CKD) patients. Methods: This is a prospective randomized controlled trial. Twelve adult obese CKD patients were randomly assigned to dietary instruction alone group (Group-D) or to both dietary instruction and exercise training group (Group-E). All patients received supervised dietary advice including calorie, protein, and salt intake for a period of 12 weeks. In addition, patients in Group-E underwent a fitness-training program. A change in glomerular filtration rate (GFR) was the main outcome. Secondary outcomes were changes in body mass index, serum creatinine-based estimated-GFR, serum albumin, and albuminuria. Results: Changes in GFR and all secondary outcomes were not statistically significant in either of the two groups. Although exercise training did not appear to significantly affect serum albumin levels in either group, it did present with a large sized effect. Conclusion: Exercise training might not have any effect on kidney function;however, the combination of exercise training along with dietary advice may prove to be more effective in maintaining the nutrition status when compared with dietary instructions alone in obese CKD patients. These results suggest that appropriate exercise training with dietary instructions is recommended for the treatment of obese CKD patients.

Successful hepatic resection for recurrent hepatocellular carcinoma after lenvatinib treatment:A case report

BACKGROUND Lenvatinib has been shown to be noninferior to sorafenib regarding prognosis and recurrence rate in patients with unresectable hepatocellular carcinoma(HCC)who have not received prior systemic chemotherapy.In patients treated with lenvatinib,40%of cases achieved sufficient tumor reduction to make potential surgery possible.However,the outcomes of such surgery are unknown.We report a successful case of hepatic resection for recurrent HCC after lenvatinib treatment.CASE SUMMARY A 69-year-old man underwent right anterior sectionectomy for HCC in segment 8 of the liver.Ten months later,he was found to have an intrahepatic HCC recurrence that grew rapidly to 10 cm in diameter with sternal bone metastases.After confirming partial response to lenvatinib administration for 2 mo,a second hepatectomy was performed.Pathological examination showed that 80%of the tumor was necrotic.The patient did not develop any adverse effects under lenvatinib treatment.He was discharged at 25 d after surgery.Radiation therapy for bone metastases continued to be given under lenvatinib,and the patient has remained alive for 1 year after the second hepatectomy.CONCLUSION The prognosis of patients with recurrent HCC may be improved by liver resection combined with prior lenvatinib therapy.

Long-term growth of intrahepatic papillary neoplasms: A case report

BACKGROUND Intraductal papillary neoplasm of the bile duct (IPNB) is a type of tumor that presents in the intra- or extrahepatic bile ducts. Cystic-type intrahepatic IPNB often mimics simple liver cysts, making the diagnosis difficult. Because the growth of IPNB is slow, careful follow-up and timely therapeutic intervention is recommended. There are few reports with a follow-up period longer than a decade;thus, we report the case of a patient with an IPNB that grew for over 13 years. CASE SUMMARY A 65-year-old man was diagnosed, 13 years prior with a cystic hepatic tumor with abnormal imaging findings. The targeted tumor biopsy results showed no malignancy. Biannual follow-up examinations were performed because of the potential for malignancy. The cystic lesions showed gradual enlargement over 11 years and a 4 mm papillary proliferation appeared on the cyst wall, which is compatible with IPNB. The tumor was observed for another 2 years because of the patient’s wishes. The imaging findings showed enlargement to 8 mm and a new 9 mm papillary proliferation of the cystic tumor. Contrast-enhanced ultrasonography showed hyperenhancement during the arterial phase in both cyst walls, indicating intraductal tumor progression in both tumors. Thus, liver segment 8 subsegmentectomy was performed. The pathological findings indicated that the tumors contained mucin, and high-grade atypia was observed in the papillary lesions, showing IPNB.CONCLUSION The development of IPNB should be monitored in patients with cystic lesions and ultrasonography are useful tool for the evaluation.
