Anemia, overhydration, and lower muscle strength in hemodialysis patients with protein-energy wasting.

Introduction: The protein-energy wasting (PEW) syndrome is a common complication in hemodialysis (HD) patients associated to morbidity and mortality. Our objective was to assess the prevalence of PEW and its association with erythropoietin resistance index (ERI) score, body composition by impedance, health-related quality of life, and muscle strength.

Methods: In this cross-sectional, observational, multicenter study, we included data from 191 HD patients from three HD clinics located in Mexico City, Mexico.

Progressive supranuclear palsy as differential diagnosis of Parkinson's disease in the elderly.

Introduction: Progressive supranuclear palsy (PSP) is a syndrome characterized by progressive parkinsonism with early falls due to postural instability, typically vertical gaze supranuclear ophthalmoplegia, pseudobulbar dysfunction, neck dystonia and upper trunk rigidity as well as mild cognitive dysfunction. Progressive supranuclear palsy must be differentiated from Parkinson's disease taking into account several so-called red flags.

Materials And Methods: We report a case series hallmarked by gait abnormalities, falls and bradykinesia in which Parkinson's disease was the initial diagnosis.

Clinical impact of indirect markers of renal function in elderly patients with hip fracture.

Introduction: There are risk factors associated with mortality in patients older than 70 years with hip fracture, including kidney function. However, indirect formulas to calculate glomerular filtration rate are not validated in patients older than 70 years. We analyzed whether the formula hematocrit, urea, and gender (HUGE) can be used as a prognostic factor.
