Frailty refers to the lack of resilience and a reduction in a person’s ability to recover following a health problem, and it is increasingly becoming a challenging aspect of ageing populations.Many older adults are exposed to polypharmacy; i.e., they continue to be on medications without timely re-evaluation. Medication reviews have proven successful in managing polypharmacy in the general populat

BACKGROUND: Infancy perfluoroalkyl substances (PFAS) exposure from breastfeeding is partially determined by the transfer efficiencies (TEs) of PFAS from maternal serum into breast milk. However, to our knowledge there are no studies of such TEs in highly exposed populations. OBJECTIVES: We estimated the TEs of PFAS from maternal serum into colostrum and breast milk in a cohort of women with a wide

Purpose We determined the characteristics of Chinese men undergoing initial prostate biopsy and evaluated the relationship between prostate specific antigen levels and prostate cancer/high grade prostate cancer detection in a large Chinese multicenter cohort. Materials and Methods This retrospective study included 13,904 urology outpatients who had undergone biopsy for the indications of prostate

Background. A better assessment of individualized prostate cancer (PrCa) risk is needed to improve screening. The use of the prostate-specific antigen (PSA) level for screening in the general population has limitations and is not currently advocated. Approximately 100 common single nucleotide polymorphisms (SNPs) have been identified that are associated with the risk of developing PrCa. The PROFIL

Two large-scale randomized screening trials, the Prostate, Lung, Colorectal and Ovary (PLCO) cancer trial in the USA and the European Randomized Screening for Prostate Cancer (ERSPC) trial in Europe are currently under way, aimed at assessing whether screening reduces prostate cancer mortality. Up to the end of 1998, 102,691 men have been randomized to the intervention arm and 115,322 to the contr

Screening for prostate cancer has been advocated by a number of organisations largely because there is good evidence that administration of the test for prostate specific antigen (PSA) results in the detection of cancers at an early stage. However, the mere fact that a cancer can be detected earlier in its natural history by screening is no guarantee that benefit will follow. Further, screening fo

Serum prostate-specific antigen is credited with dramatic advances in the early detection, screening, and management of men with prostatic carcinoma. There has been more than a twofold increase in the number of men diagnosed during the last decade, and prostate cancer has emerged as the most common non-skin cancer and the second leading cause of cancer death in men. This report summarizes the hist

Here, an acoustophoresis chip is presented that is capable of separating cancer cells from white blood cells (WBCs) and subsequently concentrating the recovered cells in the same chip. The chip utilizes ultrasound standing waves in two dimensions to pre-align, separate and concentrate the cells. 92% of the cancer cells could be recovered while keeping the contamination level of WBCs to only 0.6%.

We present an improved acoustophoretic system for circulating tumor cell separation from blood. The system is operated by pressure driven flow, including flow sensors and a feed-back loop for precise flow control. The pressure driven system provides a user interface that can be handled by a non-skilled operator, and most importantly full clinical samples of 7 mL can be processed in 70 minutes. The

We have developed a microfluidic chip for isolation of circulating tumor cells (CTCs) in blood based on microchannel acoustophoresis. Ultrasound radiation forces are used to separate cancer cells from blood cells in a continuous flow format. Separation was dramatically improved after incorporation of a 2-dimensional acoustic pre-alignment of the cells before entering the acoustophoresis separation
