ABSTRACT
BACKGROUND: Healthcare-associated infections are still a worrying health problem that complicates patient care and increases morbidity and mortality. The incidence of infections in hemodialysis patients is still high and they constitute the second cause of hospitalization and death in this category. AIMS: The study's objective was to evaluate nursing and medical staff's involvement in hospital hygiene. METHODS: This is an observational study that took place within the hemodialysis unit of a Moroccan university hospital from March 2021 to June 2021. A surface swabbing technique for bacteriological examination was also carried out. RESULTS: The study revealed some shortcomings regarding hand hygiene which was respected by the nurses in only 17.5% of sessions and in 42.2% by the doctors. Other shortcomings in asepsis measures, were also noted such as the non-change of gloves after skin preparation (1.03%) and before manual compression. The serological status of patients concerning HBV, HVC, and HIV was also not always known (31.1%). The bacteriological samples from the surfaces also showed colonization of the medical devices and the ultrasound scanner used for the ultrasound-guided introduction of the central catheters. The results of the study showed some deviations concerning the recommendations; however, they are comparable to other studies conducted internationally, especially in terms of hand hygiene. CONCLUSION: Our study results highlight some shortcomings adherence to hygiene measures like inconsistent disinfection of medical devices and dialysis stations, as well as insufficient hand hygiene practices among some staff members. However, we observed an improvement in practices following the implementation of awareness-raising sessions. To maintain improved hygiene practices and prevent infections, it is crucial to provide ongoing training for staff, ensure adequate resources, and regularly monitor compliance with hygiene standards.
ABSTRACT
Objectives: The chemical composition of cactus pear seed oil (Opuntia ficus-indica [L.] Mill.) was analyzed in terms of its fatty acid composition, tocopherol content, phenolic identification, and the oil's phenolic-rich fraction antioxidant power was determined. Methods: Fatty acid profiling was performed by gas chromatography coupled to an FI detector. Tocopherols and phenolic compounds were analyzed by LC-FLD/UV, and the oil's phenolic-rich fraction antioxidant power was determined by phosphomolybdenum, DPPH assay and ß-carotene bleaching test. Results: Fatty acid composition was marked by a high unsaturation level (83.22 ± 0.34%). The predominant fatty acid was linoleic acid (66.79 ± 0.78%), followed by oleic acid (15.16 ± 0.42%) and palmitic acid (12.70 ± 0.03%). The main tocopherol was γ-tocopherol (172.59 ± 7.59 mg/kg. In addition, Tyrosol, vanillic acid, vanillin, ferulic acid, pinoresinol, and cinnamic acid were identified as phenolic compounds in the analyzed seed oil. Moreover, the oil's phenolics-rich fraction showed a significant total antioxidant activity, scavenged DPPH up to 97.85%, and effectively protected ß-carotene against bleaching (97.56%). Conclusion: The results support the potential use of cactus pear seed oil as a functional food.
ABSTRACT
OBJECTIVE: To evaluate the in vitro antioxidant power of cactus pear seed oil [Opuntia ficus-indica L. MILL. (CPSO)] and its protective effect against chemically induced diabetes mellitus in mice. METHODS: The in vitro antioxidant effect of CPSO was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging assay. The preventive effect was conducted on Swiss albino mice treated with CPSO (2 mL/kg, per os), before and after a single intraperitoneal alloxan administration (100 mg/kg). Survival rate, body weight and fasting blood glucose were measured and histopathological analysis of pancreas was performed to evaluate alloxan-induced tissue injuries. RESULTS: CPSO exhibited an antioxidant effect in DPPH scavenging assay. Moreover, the administration of CPSO (2 mL/kg) significantly attenuated alloxan-induced death and hyperglycemia (P < 0.001) in treated mice. Morphometric study of pancreas revealed that CPSO significantly protected islets of langerhans against alloxan induced-tissue alterations. CONCLUSIONS: Based on theses results, CPSO can prevente alloxan-induced-diabetes by quenching free radicals produced by alloxan and inhibiting tissue injuries in pancreatic ß-cells.
