Augmented Package of Palliative Care for Women With Cervical Cancer: Responding to Refractory Suffering

2021

The essential package of palliative care for cervical cancer (EPPCCC), described elsewhere, is designed to be safe and effective for preventing and relieving most suffering associated with cervical cancer and universally accessible. However, it appears that women with cervical cancer, more frequently than patients with other cancers, experience various types of suffering that are refractory to basic palliative care such as what can be provided with the EPPCCC. In particular, relief of refractory pain, vomiting because of bowel obstruction, bleeding, and psychosocial suffering may require additional expertise, medicines, or equipment. Therefore, we convened a group of experienced experts in…

Full‐thickness tissue engineered oral mucosa for genitourinary reconstruction: A comparison of different collagen‐based biodegradable membranes

2020

Tissue engineering is a method of growing importance regarding clinical application in the genitourinary region. One of the key factors in successfully development of an artificially tissue engineered mucosa equivalent (TEOM) is the optimal choice of the scaffold. Collagen scaffolds are regarded as gold standard in dermal tissue reconstruction. Four distinct collagen scaffolds were evaluated for the ability to support the development of an organotypical tissue architecture. TEOMs were established by seeding cocultures of primary oral epithelial cells and fibroblasts on four distinct collagen membranes. Cell viability was assessed by MTT-assay. The 3D architecture and functionality of the ti…

Primary Mucosal Epithelial Cell Cultivation: A Reliable and Accelerated Isolation

2019

We illustrate a reliable and accelerated isolation routine for mucosal epithelial cells, which thereupon can be used for soft tissue engineering. This is highly important in the field of soft tissue engineering because mucosal equivalents are frequently usable in several surgical fields like gynecology, urology, otorhinolaryngology, ophthalmology, maxillofacial surgery, and many others. In this context the isolation of mucosal epithelial cells suitable for tissue engineering is mandatory. The reliable cultivation of mucosal or skin epithelial cells is challenging and there is currently no reproducible method. We demonstrate a solution for this problem by developing an accelerated and nevert…

A low-frequency haplotype spanning SLX4/FANCP constitutes a new risk locus for early-onset breast cancer (<60 years) and is associated with reduce…

2017

Only a fraction of breast cancer (BC) cases can be yet explained by mutations in genes or genomic variants discovered in linkage, genome-wide association and sequencing studies. The known genes entailing medium or high risk for BC are strongly enriched for a function in DNA double strand repair. Thus, aiming at identifying low frequency variants conferring an intermediate risk, we here investigated 17 variants (MAF: 0.01-0.1) in 10 candidate genes involved in DNA repair or cell cycle control. In an exploration cohort of 437 cases and 1189 controls, we show the variant rs3810813 in the SLX4/FANCP gene to be significantly associated with both BC (≤60 years; OR = 2.6(1.6-3.9), p = 1.6E-05) and…
