Background & Aims: Central venous catheter-associated bloodstream infection (CBSI) is a serious complication in patients on home parenteral nutrition (HPN). The aim was to analyze the impact of taurolidine-citrate lock solution (TLS) on CBSI rate in HPN patients with a high risk of catheter infection.
Methods: This retrospective study compared CBSI rates 12 months before and 12 months after implementation of TLS. In the first period, only standardized strategies were used to reduce the CBSI rate. In the second period, TLS was injected into the catheter at the end of parenteral nutrition. The CBSI rate with a confident interval was calculated as Poisson event rates, and compared by testing for homogeneity of rates.
Results: 15 patients were included. During the 24 months, the CBSI rate was 6.58/1000 catheter-days in the first period and 1.09/1000 catheter-days in the second period (p < 0.001). In patients with TLS once a week (n = 8), the CBSI rate decreased from 4.8/1000 catheter-days to 1.37/1000 catheter-days (p = 0.02) and in patients with TLS after each TPN (n = 7), the CBSI rate decreased from 8.61/1000 catheter-days to 0.78/1000 catheter-days (p = 0.001).
Conclusion: In HPN patients, TLS associated with standardized precautions significantly reduced the CBSI rate.

Background And Objectives: Brain energy deficiency occurs at the early stage of Huntington disease (HD). Triheptanoin, a drug that targets the Krebs cycle, can restore a normal brain energetic profile in patients with HD. In this study, we aimed at assessing its efficacy on clinical and neuroimaging structural measures in HD.

As a class of microtubule targeting agents, colchicine binding site inhibitors (CBSIs) are considered as promising drug candidates for cancer therapy. However, due to adverse reactions, there are currently no CBSIs approved by FDA for cancer treatment. Therefore, extensive efforts are still encouraged to find novel CBSIs with different chemical structures and better anticancer efficacies.

The urinary tract is considered an uncommon source of bloodstream infection (CBSI). We aimed to determine the source of CBSI in hospitalized patients, and to compare clinical and microbiological features of CBSI originating in the urinary tract (U-CBSI) and non-urinary CBSI (NU-CBSI). Of 134 patients with CBSI, 28 (20.

This single-centre retrospective study reports the dynamics of the incidence of candida bloodstream infection (CBSI) in 145 patients receiving venovenous extracorporeal membrane oxygenation (ECMO) for respiratory support between January 2014 and December 2018. The incidence rate and odds ratio (OR) of CBSI were calculated, stratified by week of ECMO exposure. Weekly incidence increased throughout the ECMO run, with an increasing trend in OR (P=0.

In autumn calving dairy herds, treatment of cattle not observed in estrus prior to the breeding season is common. Routinely, a single prostaglandin or a modified Ovsynch (MOFT) protocol are used-without evidence of their relative effectiveness. This study compares the effects on conception, associated timing, and profitability of administering cows with prostaglandin or MOFT treatment.
