Is Older Age an Independent Prognostic Factor of Survival in Metastatic Colorectal Cancer?

Introduction: Older patients (≤75 years) with advanced colorectal cancer (CRC) may have worse survival than non-older patients. We hypothesized that, rather than age alone, concurrent factors may be more relevant for real-world survival.

Methods: Patients diagnosed with CRC in a 5-year period (2014-2018) were analyzed to determine which factors influenced in overall survival (OS).

Lifelong expression of apolipoprotein D in the human brainstem: correlation with reduced age-related neurodegeneration.

The lipocalin apolipoprotein D (Apo D) is upregulated in peripheral nerves following injury and in regions of the central nervous system, such as the cerebral cortex, hippocampus, and cerebellum, during aging and progression of certain neurological diseases. In contrast, few studies have examined Apo D expression in the brainstem, a region necessary for survival and generally less prone to age-related degeneration. We measured Apo D expression in whole human brainstem lysates by slot-blot and at higher spatial resolution by quantitative immunohistochemistry in eleven brainstem nuclei (the 4 nuclei of the vestibular nuclear complex, inferior olive, hypoglossal nucleus, oculomotor nucleus, facial motor nucleus, nucleus of the solitary tract, dorsal motor nucleus of the vagus nerve, and Roller`s nucleus).

Human papillomavirus profile of women in Belize City, Belize: correlation with cervical cytopathologic findings.

Cervical carcinoma is the most common cancer among Belizean women; however, data regarding the frequency of human papillomavirus (HPV) genotypes and their association with cervical cancer are nonexistent. We therefore included HPV genotyping as part of a week-long cervical cancer screening campaign conducted in Belize City in 2007. Conventional Papanicolaou smears with Hybrid Capture (HC) 2 HPV testing were performed on 463 women.
