Assessment of quality of life using the EORTC 30 protocol in patients with soft tissue sarcoma undergoing surgical treatment.

Objective: To evaluate the quality of life among patients with Soft Tissue Sarcomas treated at the Evangelic Mackenzie Hospital (HUEM) from 2018 to 2024 and undergoing surgical treatment.

Material And Methods: descriptive and cross-sectional analysis of 23 patients with soft tissue neoplasia who underwent surgery and whether they underwent neoadjuvant or adjuvant clinical treatments. Epidemiological, clinical, and pathological data were considered.

No genetic association between the LRP receptor and sporadic or late-onset familial Alzheimer disease.

The low-density lipoprotein receptor-related protein gene (LRP1) is often mentioned as a candidate gene for Alzheimer disease (AD) because of its role as a receptor for apolipoprotein E (apoE), a major genetic risk factor for late-onset familial and sporadic AD. A recent association study of a tetranucleotide repeat polymorphism located 5' to the LRP1 gene detected an increase in the 87 base pair allele in AD cases compared to unaffected controls. Additionally, an independent study involving a genomic screen for genes associated with late-onset AD identified a region as a possible location of a late-onset AD gene on chromosome 12p between D12S373 and D12S390, about 10 cM proximal to LRP1.

No association between the HLA-A2 allele and Alzheimer disease.

The apolipoprotein E (APOE)-4 allele is a major risk factor for late-onset Alzheimer disease (AD), but it does not account for all the genetic variation in late-onset AD; thus, other genetic markers must be examined. Previous studies suggest an HLA-A2 allele association with risk and earlier onset age of AD. Because these effects may be additive to those of APOE-4, we studied HLA-A2 and APOE-4 frequencies in AD patients and cognitively intact controls.

Neuropathological features of frontotemporal dementia and parkinsonism linked to chromosome 17q21-22 (FTDP-17): Duke Family 1684.

Frontotemporal dementia with parkinsonism (FTDP-17) is an autosomal dominant disorder that presents clinically with dementia, extrapyramidal signs, and behavioral disturbances in mid-life and progresses to death within 5 to 10 years. Pathologically, the disorder is characterized by variable neuronal loss and gliosis in the frontal and temporal lobes, limbic structures, and the midbrain. Autopsied individuals from some kindreds display abundant neurofibrillary change while others, including a single affected individual from Duke Family 1684, lack distinctive histological features and exhibit only mild neuronal loss and gliosis in limbic structures and subcortical nuclei when examined by routine silver stain.
