Background And Objective: Prevention strategies are emerging with the use of catheter-lock solutions (CLS) to prevent catheter-related infections. We compared 3 CLS: heparin, citrate (46%) and heparin/gentamicin (H/G).
Design, Setting And Participants: Three periods of 6 months using the three CLS were compared.
Results: 265 catheters were studied. The CRI rate per 1,000 catheter-days was 2.9 for heparin, 3.4 for citrate and 0.4 for H/G. The free-infection catheter survival tended to be higher with H/G (log-rank test, p = 0.06) and the CRP had a significant decreasing course (p = 0.03). Since 2006 H/G was used as CLS in our dialysis unit. The resistance to gentamicin of Enterobacteriaceae increased in the nephrology department and in the entire hospital. On the other hand, the resistance of Staphylococcus aureus to gentamicin dropped to nil.
Conclusion: CLS with heparin/gentamicin tended to decrease CRI compared to citrate 46% and heparin and frankly improved the CRP course after catheter insertion. Gentamicin resistance should be monitored.

Can Intravenous Caffeine Citrate Be Used for Severe Asthma Exacerbation in Children? A Retrospective Comparative Study.
J Paediatr Child Health

Faculty of Medicine, Hebrew University of Jerusalem, Jerusalem, Israel.
Aim: To assess the effectiveness of intravenous caffeine citrate in paediatric asthma exacerbation unresponsive to beta2-agonists and steroids.
Methods: A 10-year retrospective cohort study was conducted on asthmatic children unresponsive to beta2-agonists and steroids, who were treated with either intravenous caffeine citrate or magnesium sulphate. The study outcomes were changes in the Paediatric Respiratory Assessment Measure (PRAM) score, duration of oxygen therapy and paediatric intensive care unit (PICU) length-of-stay.
Life cycle of bioethanol production from blends of different food waste.

Technology Institute, University of Passo Fundo, Passo Fundo, RS, Brazil.
Food waste offers a potential source for bioethanol production, but productivity depends on the chemical composition of the raw materials and the processes involved. However, assessment of the environmental sustainability of these processes is often absent and can be carried out using the Life Cycle Assessment (LCA) methodology. This study aimed to perform an LCA on bioethanol production from mixtures of different wastes, including tubers, fruits, and processed foods, focusing on the gate-to-gate phase.

Low phosphorus (P) use efficiency significantly impacts rice yields. An environmentally friendly approach to increase phosphorus absorption and utilization in rice involves the exploration of phosphorus-solubilizing fungal resources. This study aimed to isolate and characterize fungal strains from the rice rhizosphere and assess their phosphate solubilization capabilities, plant-growth-promoting (PGP) traits, and mechanisms involved.

Iron is the most abundant transition metal in the brain and is essential for brain development and neuronal function; however, its abnormal accumulation is also implicated in various neurological disorders. The olfactory bulb (OB), an early target in neurodegenerative diseases, acts as a gateway for environmental toxins and contains diverse neuronal populations with distinct roles. This study explored the cell-specific vulnerability to iron in the OB using a mouse model of intranasal administration of ferric ammonium citrate (FAC).

Research Background: Porang ( Blume) contains a high amount of starch, glucomannan and Ca-oxalate. Soaking porang tuber in acid (citric acid) and salt (sodium chloride) solutions affects the Ca-oxalate content, functional, rheological and thermal properties of porang flour. The aim of this study is to thoroughly investigate the effect of soaking treatments in acid and salt solutions at different temperatures on the physicochemical, rheological and thermal properties, functional groups, molecular mass and morphology of porang flour.
