Using the Montreal Cognitive Assessment Scale to screen for dementia in Chinese patients with Parkinson's Disease.

Background: Dementia is one of the most distressing and burdensome health problems associated with Parkinson's Disease (PD). The Montreal Cognitive Assessment scale (MoCA) is widely used to screen for dementia in PD patients, but the appropriate diagnostic cutoff score when used with Chinese PD patients is not known.

Aim: Determine a diagnostic cutoff value of the Chinese version of the MoCA (MoCA-C) for Chinese PD patients and describe the characteristics of PD patients screened positive for dementia using the MoCA-C.

The impact of E-cadherin expression on non-small cell lung cancer survival: a meta-analysis.

E-cadherin has been implicated in invasiveness and metastasis. However, the clinical prognostic value of decreased E-cadherin expression in patients with non-small cell lung cancer (NSCLC) remains unsettled. A meta-analysis of eligible studies was performed to quantitatively review the correlation of decreased E-cadherin expression with survival in patients with NSCLC.
