Are plasma leptin levels predictive of dementia in patients with mild cognitive impairment?
in this cohort of older adults with MCI, plasma leptin level was not associated with cognitive function at baseline, nor did it predict risk of dementia. Other biological measures, such as volumetric MRI and cerebrospinal fluid protein levels, have demonstrated robust dementia prediction in this cohort. Thus, the current negative findings suggest that plasma leptin, on its own, is unlikely to become a useful clinical biomarker for Alzheimer's disease. Efforts to develop other blood-based biomarkers are needed.
The utility of the APACHE II score in gastric cancer patients is limited. APACHE II is suitable for considering group versus individual effect. The POSSUM score is useful in general surgery, but needs improvement. We found the P-POSSUM score to be superior for morbidity and mortality prediction. P-POSSUM is useful for both the general population and for a specific cohort. The type of surgery is a key decision point for surgeons, and independently affects prognosis. Based upon these findings and clinical scoring systems, clinicians can develop individualized treatment algorithms.
