Peritoneal transport: getting more complicated
A high clearance of low-molecular substances such as urea and creatinine is generally considered advantageous in dialysis. The discovery in the 1990s of increased morbidity [1] and mortality [2, 3] in peritoneal dialysis (PD) patients with fast low-molecular (e.g. glucose, creatinine and urea) peritoneal transport (FLMT, also called ‘high transport’) was thus counterintuitive. Several explanati...
متن کاملThe thyroid axis just got more complicated.
As a first-year medical student, you could count on the simplicity and elegance of the thyroid axis, because all its details had apparently been elucidated. Hypothalamic thyrotropin-releasing hormone (TRH) promoted the synthesis, release, and glycosylation of pituitary thyrotropin, thyroid-stimulating hormone (TSH), which in turn acted on the thyroid follicle, leading to the synthesis and relea...
متن کاملObesity in the elderly: more complicated than you think.
The number of obese older adults is on the rise, although we lack a proper definition of obesity in this age group. The ambiguity is primarily related to sarcopenia, the progressive loss of muscle and gain in fat that come with aging. Whether to treat and how to treat obesity in the elderly is controversial because of a paucity of established guidelines, but also because of the obesity paradox-...
متن کاملAre more complicated tumour control probability models better?
Mathematical models for the tumour control probability (TCP) are used to estimate the expected success of radiation treatment protocols of cancer. There are several TCP models in the literature, from the simplest (Poissonian TCP) to the well-advanced stochastic birth-death processes. Simple and complex models often make the same predictions. Hence, here, we present a systematic study where we c...
متن کاملElectronic Procurement in Government: More Complicated than Just Good Business
Electronic procurement has been widely embraced by governments seeking the administrative efficiencies and cost reductions experienced in the private sector. The enthusiastic response has rarely been tempered by critical evaluation of current models for implementation of e-procurement programs. This paper examines the case of Australian government e-procurement where there has been significant ...
