METHODS: A systematic search of MEDLINE, EMBASE, CINAHL and CENTRAL was conducted to identify all randomized controlled trials in critically ill patients published from inception to June 2021, which investigated clinical omega-6 sparing effects. Two independent reviewers extracted bias risk, treatment details, patient characteristics and clinical outcomes. Random effect meta-analysis was performed.
RESULTS: 1054 studies were identified in our electronic search, 136 trials were assessed for eligibility and 26 trials with 1733 critically ill patients were included. The median methodologic score was 9 out of 14 points (95% confidence interval [CI] 7, 10). Omega-6 FA sparing PN in comparison with traditional lipid emulsions did not decrease overall mortality (20 studies; risk ratio [RR] 0.91; 95% CI 0.76, 1.10; p = 0.34) but hospital length of stay was substantially reduced (6 studies; weighted mean difference [WMD] - 6.88; 95% CI - 11.27, - 2.49; p = 0.002). Among the different lipid emulsions, fish oil (FO) containing PN reduced the length of intensive care (8 studies; WMD - 3.53; 95% CI - 6.16, - 0.90; p = 0.009) and rate of infectious complications (4 studies; RR 0.65; 95% CI 0.44, 0.95; p = 0.03). When FO was administered as a stand-alone medication outside PN, potential mortality benefits were observed compared to standard care.
CONCLUSION: Overall, these findings highlight distinctive omega-6 sparing effects attributed to PN. Among the different lipid emulsions, FO in combination with PN or as a stand-alone treatment may have the greatest clinical impact.

Methods: In vitro, physicochemical properties of the Stattic-entrapped C-PLGA nanoparticles (S@C-PLGA) and Stattic-entrapped PLGA nanoparticles (S@PLGA, control) in terms of size, zeta potential, polydispersity index, drug loading, entrapment efficiency, Stattic release in different medium and cytotoxicity were firstly evaluated. The in vitro antimigration properties of the nanoparticles on breast cancer cell lines were then studied by Scratch assay and Transwell assay. Study on the in vivo antitumor efficacy and antimetastatic properties of S@C-PLGA compared to Stattic were then performed on 4T1 tumor bearing mice.
Results: The S@C-PLGA nanoparticles (141.8 ± 2.3 nm) was hemocompatible and exhibited low Stattic release (12%) in plasma. S@C-PLGA also exhibited enhanced in vitro anti-cell migration potency (by >10-fold in MDA-MB-231 and 5-fold in 4T1 cells) and in vivo tumor growth suppression (by 33.6%) in 4T1 murine metastatic mammary tumor bearing mice when compared to that of the Stattic-treated group. Interestingly, the number of lung and liver metastatic foci was found to reduce by 50% and 56.6%, respectively, and the average size of the lung metastatic foci was reduced by 75.4% in 4T1 tumor-bearing mice treated with S@C-PLGA compared to Stattic-treated group (p < 0.001).
Conclusion: These findings suggest the usage of C-PLGA nanocarrier to improve the delivery and efficacy of antimetastatic agents, such as Stattic, in cancer therapy.
Methods: Analytical cross-sectional study undertaken among a convenient sample of medical and non-medical colleges of Ajman University using a self-administrated questionnaire. The questionnaire included demographic data as well as assessing knowledge of COVID-19, attitudes and acceptance of COVID-19 vaccines.
Results: A total of 467 students participated in the study and completed the questionnaire. A total of 181 (38.8%) participants reported that they have been vaccinated against COVID-19 virus, principally with the Sinopharm vaccine (84%). Vaccination against the COVID-19 virus was less prevalent among Arabic nationalities compared to other nationalities, but more prevalent among students from health science colleges compared to those from non-health science colleges. The acceptance rate of COVID-19 vaccine among study participants was 56.3%, exacerbated by worries regarding unforeseen problems (65.5%, 306), general mistrust (47.3%, 221) and unforeseen impacts (35.1%, 164). The average knowledge score was 60.1%, with 142 (30.4%) having poor knowledge, 127 (27.2%) acceptable knowledge and 198 (42.4%) good knowledge. There were common misconceptions about symptoms including nausea and diarrhoea, as well as the route of transmission, with half believing antibiotics are effective treatment.
Conclusion: There was variable knowledge of COVID-19 among students. Misconceptions need addressing going forward. To enhance COVID-19 vaccination uptake in the country and worldwide, health education targeting diverse sociodemographic categories should be prioritized.
Methods: A qualitative study was conducted with pharmacists practicing in airport pharmacies from June 2020 to December 2020. A validated Google form-based interview questionnaire was developed, and the electronic link was sent to the participants. Recruitment of participants was continued until data saturation was achieved. In total, 15 pharmacists working at different airport pharmacies in different countries were included. Thematic analysis was used in the data analysis.
Results: The study identified six major themes including type of professional services and medicines at airport pharmacies, pharmacists' experiences, challenges at the airport pharmacy, suggestions to improve airport pharmacy services, pandemics and the role of pharmacists, and business aspect of the airport pharmacies. The study showed that several professional services provided at airport pharmacies, including the provision of medicines, health products, general health services, travel health services, and counseling. Moreover, 46.7% of the participants reported having a dedicated travel health service. In addition, most of the participants described their experience at airport pharmacies as good and exciting as they met different people from different countries. The most common challenges that pharmacists face at airport pharmacies include language barriers, requests for different medicine brands by travelers, and financial issues. The participants indicated that there is a need for promotion of pharmacists' role in providing health care services at airport pharmacies.
Conclusion: The study showed that pharmacists could play vital roles in providing medicines and health care services for air travelers. However, there is still further scope for improvement in this sector of the pharmacy profession to ensure a more active role in travel medicine.
Methods: Crocodylus porosus was procured, blood collected, dissected and lysates prepared from internal organs. Organ lysates and sera were tested for growth inhibition, cytotoxic effects and cell survival against HeLa, PC3 and MCF7 cells and subjected to liquid chromatography mass spectrometry. RNA transcriptome analysis and differential gene analysis were performed using Galaxy Bioinformatics.
Results: Sera exhibited potent growth inhibition and cytotoxic effects against cancer cells. 80 molecules were detected from C. porosus and 19 molecules were putatively identified. Additionally, more than 100 potential anticancer peptides were identified from sera using bioinformatics based on peptide amino acid composition, binary profile, dipeptide composition and pseudo-amino acid composition. Following transcriptome analysis, 14 genes in treated HeLa cells, 51 genes in treated MCF7 cells and 2 genes in treated PC3 cells, were found to be expressed, compared with untreated controls.
Conclusion: Animals residing in polluted milieus are an unexploited source for prospective pharmaceutical drugs, and could lead to identification of novel antitumour compound(s) and/or further understanding of the mechanisms of cancer resistance.
Design setting and participants: Behavioral and EEG data were acquired from dental surgery trainees with 1 year (n=25) and 4 years of experience (n=20) while they performed low and high difficulty drilling tasks on a virtual reality surgical simulator. EEG power in the 4-7 Hz range in frontal electrodes (indexing frontal theta) was examined as a function of experience, task difficulty and error rate.
Results: Frontal theta power was greater for novices relative to experts (p=0.001), but did not vary according to task difficulty (p=0.15) and there was no Experience × Difficulty interaction (p=0.87). Brain-behavior correlations revealed a significant negative relationship between frontal theta and error in the experienced group for the difficult task (r=-0.594, p=0.0058), but no such relationship emerged for novices.
Conclusion: We find frontal theta power differentiates between surgical experiences but correlates only with error rates for experienced surgeons while performing difficult tasks. These results provide a novel perspective on the relationship between expertise and surgical performance.
