Level of knowledge and quality of life among Saudi caregivers of Parkinson's disease patients: A study from a tertiary hospital in Riyadh, Saudi Arabia.

Purpose: We aimed to assess the family caregivers' level of knowledge and attitudes about Parkison's disease (PD), identify factors affecting their knowledge, evaluate their quality of life (QoL) and factors influencing it and to define the effect of PD on activities of daily living (ADLs) of PD patients.

Method: We developed and validated a questionnaire to assess the level of knowledge and attitudes of family caregivers toward PD, effects of PD on caregivers' QoL as well as its effects on activities of daily living (ADLs) of patients from the caregivers' perspective. A scoring system was utilized and SPSS was used to evaluate the differences in responses between the groups; p < 0.

Diabetic Hearts Exhibit Global DNA Hypermethylation That Alter the Mitochondrial Functional Genes to Enhance the Sensitivity of the Heart to Ischemia Reperfusion Injury.

A recent study has shown that DNA hypermethylation can promote ischemia reperfusion (I/R) injury by regulating the mitochondrial function. Diabetes mellitus (DM) is reported to induce DNA hypermethylation, but whether this prior DNA methylation in DM I/R heart inflicts a beneficial or detrimental effect is not known and is addressed in this study. DM was induced in 6-week-old male Wistar rats with streptozotocin (65 mg/kg b.
