Effect of evidence-based nursing practices training programme on the competency of nurses caring for mechanically ventilated patients: a randomised controlled trial.

BACKGROUND: Evidence-Based Practice (EBP) has been recognised worldwide as a standardised approach for enhancing the quality of healthcare and patient outcomes. Nurses play a significant role in integrating EBP, especially in Intensive Care Unit (ICU). Consequently, this study aims to examine the effect of an adapted evidence-based nursing practices training programme on the competency level of nurses caring for mechanically ventilated patients. METHODS: A prospective open-label parallel 1:1 randomised controlled trial was conducted on 80 nurses caring for ICU patients at the National Hepatology and Tropical Medicine Research Institute, Egypt. The trial was carried out between November 2022 and February 2023 under the registration number NCT05721664. The enrolled nurses were randomly divided into intervention and control groups. The intervention group received the evidence-based nursing practice training programme (EBNPTP) in accordance with the Johns Hopkins EBP conceptional model, whereas the control group received traditional in-service education. Four assessments (one pre- and three post-assessments) were conducted to evaluate nurses' competency level over time using the adapted evidence-based nursing competency assessment checklist. The primary endpoint was an increase the competency levels among nurses caring for mechanically ventilated patients. RESULTS: The current study results revealed statistically significant differences between intervention and control groups in relation to their level of competency across the three post-assessments, with (p <.001). The study also demonstrated that the nurses' competency level continued to decline significantly over time, with (p <.001). Additionally, a significant correlation was found between the nurses' pre-assessment and educational level, acting as independent variables (predictors), and the third endpoint assessment (p <.01), indicated by multiple linear regression. CONCLUSION: The EBP training programme demonstrated a significant increase in the nurses' level of competency compared with traditional in-service education. This suggests that by training the nurses in various settings with the essential skills and knowledge for EBP, their competency level can be enhanced, leading to the delivery of effective care and improving patient outcomes. However, the long-term sustainability of the EBP adoptions was insufficient; further studies are needed to investigate the factors that affect the durability of EBP adoption. TRIAL REGISTRATION: The study was registered with Clinical Trials.gov (Registration # NCT05721664) on 10/02/2023.

Immunohistochemical Expression of Claudin-1 and Claudin-4 in Urothelial Carcinoma of the Urinary Bladder.

BACKGROUND: In Egypt, bladder cancer occupies the second rankamong reported cancers in men. Claudins are tight junctions that have a critical role in tumor pathogenesis, invasion, progression, and metastasis and currentlyare a focus of interest for targeting therapies. OBJECTIVES: We aimed to evaluatethe immunohistochemical expression of Claudin-1 and Claudin-4 in urinary bladder urothelial carcinoma and investigate the relationshipbetweenthe expressed Claudins with differentclinicopathological parameters. METHODS: Claudin-1 and Claudin-4 immunohistochemical expression was studied in 62 cases of urinary bladder urothelial carcinomas. The cases were classified into two categories; low and high Claudin-1 and Claudin-4 expression. RESULTS: High Claudin-1 expression was detected in67.7% of the studied urothelial carcinomas while 32.3% showed low expression. Claudin-1 expression was reduced significantly with high tumor grade, non-papillary tumors, muscle invasion, schistosomal infestation, and perineural invasion (p-value < 0.05). Claudin-4 high expression was detected in 82.3% of our cases while low expression was detected in 17.7%. Claudin-4 reduced expression was significantly associated with non-papillary tumors, muscle invasion, advanced T stages, and associated lympho-vascular emboli (P-value < 0.05). CONCLUSION: According to the results ofthe present study, the reduced expressions of Claudin-1 and Claudin-4 provide clues concerning the progression of urothelial carcinoma. Consequently, it is thought that Claudin-1 and Claudin-4 could help to differentiatelow-grade from high-grade and muscle-invasive from non-muscle-invasive urothelial carcinomas. In addition, it can be introduced as a possible therapeutic target.

Observational, prospective, single-center study: Should body mass index be added to the scoring criteria of hepatic critically ill patients in the intensive care unit.

BACKGROUND: Obesity has recently become more prevalent, and thus the coexistence of liver cirrhosis with obesity has become very pervasive. The purpose of this study is to investigate the correlation between abnormal body mass index (BMI) (overweight and obese) and clinical outcomes in critically ill cirrhotic patients. METHODS: This is a single-center, prospective observational study of cirrhotic patients admitted to the intensive care unit for either medical or surgical indications in the period from February 2018 to December 2020. Patients were categorized based on their body mass index and the reason for admission to the intensive care unit (ICU). RESULTS: The current study enrolled 517 patients; 39.3% were overweight, and 19.5% were obese (85% were class 1 and 2). Surgical subgroup analysis revealed that the hospital stay was shorter in the obese than average weight patients (p-value= 0.039), and ICU stay was shorter in overweight patients than patients with average weight (p-value= 0.022). The incidence of acute kidney injury was shorter in the obese group than in overweight and average-weight patients (p-value= 0.045). The medical subgroup analysis revealed that the need for noninvasive ventilation was lower in the obese and overweight groups than in the normal group (p-value= 0.040). CONCLUSIONS: Despite having similar Child-Pugh (CP) and Sequential Organ Failure Assessment Score (SOFA) scores on admission, obese patients had better outcomes than non-obese patients, demonstrating the obesity paradox. Further research is required on BMI as a predictive score in a patient with critical cirrhosis as an indicator of obesity.

Evaluation of procalcitonin (PCT) as a marker of infection in early post living donated liver transplant period.

BACKGROUND AND AIM: Procalcitonin (PCT) has been increasingly used as a biomarker of bacterial infection and as a tool to guide antimicrobial therapy. Despite its increased use, data in patients with solid organ transplants are limited. The study aimed to assess the frequency of rising PCT associated with infectious complications in immunosuppressed living donated liver transplantation. METHODS: A single-center, retrospective observational study. Preoperative patients' demographic data, operative, anesthetic data, and postoperative clinical course were analyzed post-liver transplant (LT) till discharge from the intensive care unit. RESULTS: Sixty patients were classified according to the culture results' into a positive culture group & a negative one and then followed up the sepsis variables in each group. Total leukocyte count (TLC) was elevated in the positive culture group in comparison to the negative culture one and was statistically significant (P-value <0.05) till the fourth day postoperative. Procalcitonin was higher in the positive culture group than in the negative one on days 1, 3, and 5 postoperative and was statistically significant (P-value <0.05). The cutoff values in the receiver operating characteristic curve (ROC) with >90% specificity to infection post LT were PCT of ≥9 ng/ml and TLC of ≥17.3/mm3 on day one. CONCLUSIONS: Following up PCT level on day one with TLC is essential and will help to detect sepsis and guide early antimicrobial initiation post-liver transplantation. Combined measurements of PCT and TLC with cutoff values of <9 ng/ml and < 17.3/mm3 respectively will help to exclude infections in 83.7% of patients, thus avoiding unnecessary usage of higher generations empiric antimicrobials.

Norepinephrine is More Effective Than Midodrine/Octreotide in Patients With Hepatorenal Syndrome-Acute Kidney Injury: A Randomized Controlled Trial.

Background: Terlipressin is the first-line pharmacological treatment for hepatorenal syndrome. When terlipressin is unavailable, midodrine/octreotide or norepinephrine, with albumin, represent the alternative treatments. The comparative efficacy of these alternative regimens remains unclear. Objective: To compare the efficacy of midodrine/octreotide to that of norepinephrine for the treatment of patients with hepatorenal syndrome. Methods: In the intensive care setting, sixty patients with hepatorenal syndrome were randomized to initially receive either 0.5 mg/h of norepinephrine (maximum 3 mg/h) or 5 mg of oral midodrine three times/day (maximum 12.5 mg three times/day) plus octreotide (100 µg/6 h) as subcutaneous injection (maximum 200 µg/6 h), together with albumin (20-40 g/day). Treatment was allowed for a maximum of 10 days. Survival was analyzed for up to 30 days. The primary efficacy outcome was the proportion of patients who achieved full response, defined as the return of serum creatinine to a value within 0.3 mg/dl of the baseline at the end of treatment. Results: There was a significantly higher rate of full response in the norepinephrine group (15/26, 57.60%) than the midodrine/octreotide group (5/25, 20%) (p = 0.006). Eleven (42.30%) patients in the norepinephrine group and 6 (24%) in the midodrine/octreotide group survived (p = 0.166). Conclusion: Norepinephrine plus albumin is significantly more effective than midodrine and octreotide plus albumin in improving renal function in patients with hepatorenal syndrome.

Impact of pre-transplant infection management on the outcome of living-donor liver transplantation in Egypt.

BACKGROUND AND AIM: Liver transplantation (LT) has emerged as an established therapeutic option for patients with chronic liver disease. Patients with end-stage liver disease are at high risk of infection with multidrug-resistant organisms, which may affect the outcome of LT. The aim of this study was to evaluate the impact of pre-transplant infection on the outcome of living-donor LT. METHODS: Prospective follow-up was done for 50 patients with chronic liver disease who had had LT performed from September 2013 to December 2017. We divided patients into group 1 (patients who had had infection within 3 months before transplantation with adequate treatment [n=20]), and group 2 (patients without infection [n=30]). Both groups were followed for 4 months post-operatively. RESULTS: Patients with high Model for End-Stage Liver Disease scores were more susceptible to infection pre- and post-operatively, and chest infection was the most common infection pre-transplant. There were no significant statistical differences regarding hospital and ICU stay and post-operative course between the groups, but the mortality rate was higher in group 1 (40%) than in group 2 (23.3%), and the causes of mortality in the group 1 were mainly due to medical causes (infections and sepsis, 75%) versus 28.6% in group 2. CONCLUSION: Liver-cell failure and concomitant infection 3 months before LT with adequate treatment had no significant statistical differences regarding hospital, ICU stay, or medical complications, but post-operative infection and mortality rate were more frequent in group 1 and the causes of mortality were mainly medical.
