Randomized Controlled Trial
Randomized clinical trial of autologous skin cell suspension for accelerating re-epithelialization of split-thickness donor sites.
Split-thickness skin graft (STSG) is used frequently, but may result in complications at the donor site. Rapid healing of donor-site wounds is critical to relieving morbidity. This study investigated whether autologous skin cell suspension could improve healing of STSG donor-site wounds. ⋯ The use of autologous skin cell suspension with hydrocolloid dressings accelerated epithelialization and improved healing quality of the donor site compared with hydrocolloid dressings alone. Registration number: UMIN000015000 ( http://www.umin.ac.jp/ctr).

A significant proportion of patients with chronic kidney disease and secondary hyperparathyroidism (HPT) remain hyperparathyroid after kidney transplantation, a state known as tertiary HPT. Without treatment, tertiary HPT can lead to diminished kidney allograft and patient survival. Parathyroidectomy was commonly performed to treat tertiary HPT until the introduction of the calcimimetic drug, cinacalcet. It is not known whether surgery or medical treatment is superior for tertiary HPT. ⋯ Side-effects and complications of both treatment modalities were mild and occurred in a minority of patients. Surgical treatment for tertiary HPT has higher cure rates than medical therapy.

Multicenter Study
Prognostic factors for survival in patients with pT1 N+ or T2-3 N0 gastric cancer in Japan.
The outcome for pT1 N+ or pT2-3 N0 gastric cancer is favourable, but some patients suffer from recurrent disease. The aim of this study was to identify prognostic factors in patients with pT1 N+ or pT2-3 N0 gastric cancer. ⋯ Survival of patients with pT1 N+ or pT2-3 N0 gastric cancer is good. Age 65 years or above, male sex and cT2-4 category are associated with worse overall survival.

Observational Study
Acute kidney injury and mortality 1 year after major non-cardiac surgery.
Even mild and transient acute kidney injury (AKI), defined by increases in serum creatinine level, has been associated with adverse outcomes after major surgery. However, characteristic decreases in creatinine concentration during major illness could confound accurate assessment of postoperative AKI. ⋯ Although the majority of postoperative AKI was mild, there was a strong association with risk of death in the year after surgery. Underlying decreases in serum creatinine concentration after major surgery could lead to underestimation of AKI severity and overestimation of recovery.

The patterns, predictive factors and prognostic impact of multilevel metastasis in patients with N1b papillary thyroid carcinoma (PTC) were investigated. ⋯ Level V metastasis rather than multilevel metastasis itself is associated with an increased risk of LRR. Patients with N1b PTC and level V metastasis require risk restratification and meticulous follow-up.
