PROBLEM: Question: Are findings in the distal colorectum associated with proximal advanced serrated lesions?
Answer: The findings at flexible sigmoidoscopy that traditionally serve as indications for colonoscopy (conventional adenomas) are likely to be ineffective for detection of proximal ASL. This finding, plus the observation that most patients with proximal ASL have no distal polyps, favors screening colonoscopy over sigmoidoscopy, especially in the elderly. The observation that non-advanced distal SSA/Ps are associated with any proximal SSA/P warrants further study.

SOLUTION: no

PROBLEM: Question: Do extremely cold and hot temperatures increase the risk of diabetes mortality in metropolitan areas of two Chinese cities?
Answer: The results indicate that both extremely cold and hot temperatures increase diabetes mortality in different manners in Harbin and Chongqing. Diabetes education programs should include information on either managing or combating the effects of extreme hot and cold weather.

SOLUTION: yes

PROBLEM: Question: Does spinal instrumentation in patients with primary spinal infections lead to greater recurrent infection rates : an analysis of 118 cases?
Answer: Patients who received just decompression for spinal infection had similar reoperation and continued infection rates as patients who additionally underwent instrumentation, irrespective of infection location within the spine. These findings suggest that instrumentation of the infected spine may be a safe treatment modality and should be considered when the spinal integrity is compromised.

SOLUTION:
no
