Brain white matter microstructural changes in chemotherapy-treated older long-term breast cancer survivors.

Purpose: To assess white matter microstructural changes in older long-term breast cancer survivors 5-15 years post-chemotherapy treatment.

Methods: Breast cancer survivors aged 65 years or older who underwent chemotherapy (C+) and who did not undergo chemotherapy (C-) and age- and sex-matched healthy controls (HC) were enrolled at time point 1 (TP1) and followed for 2 years for time point 2 (TP2). All participants underwent brain MRI with diffusion tensor images and neuropsychological (NP) testing with the NIH Toolbox Cognition Battery.

Practical Considerations in Hospital Infection Prevention.

Inpatient infection prevention practices vary widely between health care institutions, on a national and international scale. Transmissible infectious diseases pose a risk to vulnerable inpatient populations as well as hospital staff and visitors. Maintaining a high index of suspicion, along with early identification and prompt isolation procedures of patients with these conditions can greatly reduce the likelihood of transmission.

Altered gyrification in chemotherapy-treated older long-term breast cancer survivors.

Purpose: The purpose of this prospective longitudinal study was to evaluate the changes in brain surface gyrification in older long-term breast cancer survivors 5 to 15 years after chemotherapy treatment.

Methods: Older breast cancer survivors aged ≥ 65 years treated with chemotherapy (C+) or without chemotherapy (C-) 5-15 years prior and age & sex-matched healthy controls (HC) were recruited (time point 1 (TP1)) and followed up for 2 years (time point 2 (TP2)). Study assessments for both time points included neuropsychological (NP) testing with the NIH Toolbox cognition battery and cortical gyrification analysis based on brain MRI.

Cortical thinning in chemotherapy-treated older long-term breast cancer survivors.

Cognitive decline is an increasing issue for cancer survivors, especially for older adults, as chemotherapy affects brain structure and function. The purpose of this single center study was to evaluate alterations in cortical thickness and cognition in older long-term survivors of breast cancer who had been treated with chemotherapy years ago. In this prospective cohort study, we enrolled 3 groups of women aged ≥ 65 years with a history of stage I-III breast cancer who had received adjuvant chemotherapy 5 to 15 years ago (chemotherapy group, C +), age-matched women with breast cancer but no chemotherapy (no-chemotherapy group, C-) and healthy controls (HC).

Signal Variability and Cognitive Function in Older Long-Term Survivors of Breast Cancer with Exposure to Chemotherapy: A Prospective Longitudinal Resting-State fMRI Study.

The purpose of this study was to assess the effect of chemotherapy on brain functional resting-state signal variability and cognitive function in older long-term survivors of breast cancer. This prospective longitudinal study enrolled women age ≥ 65 years of age who were breast cancer survivors after exposure to chemotherapy (CH), age-matched survivors not exposed to chemotherapy, and healthy controls. Participants completed resting-state functional brain MRI and neurocognitive testing upon enrollment (timepoint 1, TP1) and again two years later (timepoint 2, TP2).

Synchronous Penile Squamous Cell Carcinoma, Bladder Urothelial Carcinoma and Prostate Adenocarcinoma Diagnosed in One Procedure.

Background: The synchronous diagnoses of three primary malignancies in a patient is rare and represents a difficult treatment challenge. We report a rare case of an 81-year-old male with synchronous triple urogenital cancers including penile squamous cell carcinoma, bladder papillary urothelial carcinoma, and prostate adenocarcinoma.

Case Report: The patients presented with a penile lesion with blood draining through the foreskin.

Unexpected Reason for Non-healing Oral Ulcers: Syphilis.

Syphilis is a sexually transmitted infectious disease caused by Treponema pallidum and characterized by a complex and variable clinical presentation. Cases of unexpected oral syphilis presenting as non-healing ulcers are uncommonly reported. We report 3 cases (one female and two males, aged 35, 35, and 56 years, respectively) in which patients presented with non-healing oral ulcers.

Synthesis of biocompatible polymeric hydrogels with tunable adhesion to both hydrophobic and hydrophilic surfaces.

We report the synthesis of biocompatible polymeric hydrogels based on poly(vinyl acetate) (PVAc) and poly(methyl vinyl ether-co-maleic anhydride) (PMVE-MA). These polymeric hydrogels show strong and tunable adhesion to both hydrophobic and hydrophilic surfaces and should be ideal candidates as bioadhesives for applications such as denture adhesion. PVAc was partially hydrolyzed and then mixed with PMVE-MA.
