Home blood pressure is important because it is more strongly associated with target organ damage and total mortality than clinic blood pressure measurements. Regular moderate aerobic exercise has antihypertensive effects. This study aims to examine the effect of aerobic exercise therapy on blood pressure at home in patients with diabetes.Patients and Methods: In this crossover randomized controlled trial, 110 patients with type 2 diabetes will be randomly assigned to two groups: an exercise preceding group and an exercise lagging group. During the exercise period, patients will be instructed to walk either 30 minutes twice each day or 60 minutes once each day for at least 3 days per week. During the non-exercise period, patients will be permitted to perform physical activity associated with activities of daily life. Patients will be followed up for 56 days. The primary outcome will be the mean nocturnal blood pressure from day 24 to 28 during the exercise period compared to that during the non-exercise period. The secondary outcome will include variation in nocturnal blood pressure, mean blood pressure values and variation of morning and evening blood pressure from day 24 to 28 in the exercise period compared to the non-exercise period, body weight, body mass index and bioelectrical impedance analysis. Biochemical tests such as hemoglobin A1c level, blood glucose level, serum lipid profile, renal function, uric acid levels and liver function tests will also be measured.Discussion: This randomized controlled trial will provide critical information regarding the effectiveness of moderate exercise on nocturnal blood pressure reduction. If successful, the results of this randomized controlled trial may increase exercise motivation in people with diabetes and may lead to improvement or prevention of target organ damage and overall mortality.Trial Registration: Trial registration: University Hospital Medical Information Network, UMIN 000035973.

Iwai K, Ushigome E, Yokota I, et al. Diabetes Metab Syndr Obes. 2020;13:4747–4753. The authors have advised there was an error in the Institutional Review Board’s protocol version number. The correct protocol version number should read from R000040969 to ERB-C-1463-2. On page 4747, Abstract, Trial Registration section, the text “Protocol version number: R000040969. Registration date: February 22, 2019. Recruitment began: June 19, 2019” should read “Protocol version number: ERB-C-1463-2. Registration date: February 22, 2019. Recruitment began: June 19, 2019”. On page 4751, Ethics Approval and Informed Consent section, third sentence, the text “Protocol modifications will be approved by the medical research ethics committee of the Hospital of the Kyoto Prefectural University of Medicine (protocol reference number: R000040969)” should read “Protocol modifications will be approved by the medical research ethics committee of the Hospital of the Kyoto Prefectural University of Medicine (protocol reference number: ERB-C-1463-2)”. The authors wish to apologize for the error. Read the original article

A 60-year-old woman who had had a history of renal cell carcinoma with intraperitoneal recurrence presented with multiple liver masses. Computed tomography demonstrated multiple enhancing lesions in the both lobes of the liver, and there was an apparent small vessel coursing within one of the lesions. On magnetic resonance imaging, masses showed slight T1 and T2 prolongation, and restricted diffusion: On the hepatobiliary phase of liver-specific contrast agent enhancement, lesions were shown as low signal intensity of varying degree. Liver metastases from renal cell carcinoma were suspected, and partial hepatectomy was performed for the superficially located nodules to make a definitive diagnosis. The final pathological diagnosis was reactive lymphoid hyperplasia or pseudolymphoma of the liver. [ABSTRACT FROM AUTHOR]
