Background: Recent data suggest that serum albumin concentrations increase during the several month-period that follows the initiation of maintenance hemodialysis (MHD) therapy. Some investigators have shown that the rate of increase in serum albumin level is related directly to 24-hour urine protein losses before the initiation of dialysis therapy. However, serum albumin levels increase even in patients starting MHD therapy without significant proteinuria, suggesting that this increase may be one manifestation of improving protein-energy nutritional status associated with commencing MHD therapy. We examined this question by reviewing records of all patients admitted to our outpatient dialysis unit within 30 days of initiation of MHD therapy.
Methods: Ninety-seven patients qualified for the study. Their routine laboratory test results beginning with the time of admission to the outpatient unit until month 6 of chronic dialysis therapy were analyzed.
Results: Between months 1 and 6, there was a statistically significant increase in values for predialysis serum albumin, iron, transferrin saturation, creatinine, and normalized protein equivalent of total nitrogen appearance (nPNA). Many of these values were still increasing by month 6. Body weight declined initially until month 4, then increased. There was a strong curvilinear relationship between mean nPNA and final serum albumin level.
Conclusions: Our results suggest that an improvement in nutritional status, including an increase in dietary protein intake and serum albumin level, often occurs with the initiation of MHD therapy. The improvement in nutritional status may be related to the increase in dietary protein intake.

Robotic surgery is extensively used for rectal cancer treatment. Nonetheless, studies on whether to preserve the left colonic artery (LCA) during robotic rectal cancer surgery to reduce complications remain scarce and controversial. This study compared short-term outcomes of high tie (HT) and low tie (LT) ligation of the inferior mesenteric artery in 455 patients undergoing robotic rectal cancer surgery between May 2018 and July 2022.

Coarse-grained molecular dynamics simulation is widely accepted for assessment of a large complex biological system, but it may also lead to a misleading conclusion. The challenge is to simulate protein structural dynamics (such as folding-unfolding behavior) due to the lack of a necessary backbone flexibility. This study developed a standard coarse-grained model directly from the protein atomic structure and amino acid coarse-grained FF (such as MARTINI FF v2.

Background: One of the most common secondary glomerular diseases in children is IgA vasculitis-associated nephritis (IgAVN). Determining the best treatment for IgAVN based on current guidelines is controversial. The purpose of this study was to evaluate the efficacy of methylprednisolone pulse therapy in Chinese children with moderate and severe IgAVN.

Background: Adult people with cystic fibrosis (PwCF) have a higher risk of end-stage kidney disease than the general population. The nature and mechanism of kidney disease in CF are unknown. This study quantifies urinary kidney injury markers and examines the hypothesis that neutrophil activation and lung infection are associated with early kidney injury in CF.

The denatured bovine serum albumin (dBSA) is coupled with the CdTe/CdS quantum dot and the resulting CdTe/CdS@dBSA complex is assembled and retained in the poly(n-isopropyl acrylamide) (PNIPAM) hydrogel via regulating temperature and pH to form the CdTe/CdS@dBSA-PNIPAM fluorescence hydrogel substrate, which is able to adsorb and sense cadmium ions (Cd). Based on this fluorescence hydrogel, a fluorescence and colorimetric dual-mode detection system is established to quantitatively detect Cd with a limit of detection (LOD) of 2.88 nM for fluorescence detection and 11.
