Objectives: Socio-aesthetics is a practice born in psychiatric departments but has since developed particularly in the field of oncology. For our part, since January 2018, we have initiated an experiment of this type at the Espace Unit of the CHU in Nantes, a unit that takes care of young patients who find themselves in a situation of crisis and endangerment of themselves.

Methods: The qualitative evaluation of the interest of a socio-aesthetic mediation (relaxation modelling, facial care, make-up) with young patients was carried out by a collection of their feelings.

Results: Youth who expressed an overall judgment of socio-esthetic mediation appreciated it in 61% of cases. They express their satisfaction with words such as "I liked", "I loved", "I'm happy", "it was too good", "super good" or "great".

Conclusion: This successful socio-aesthetic therapy practice experiment will continue with a quantitative analysis to demonstrate the relevance of this type of service to psychiatric patients.

Objective: The present work represents a reverse-phase high-performance liquid chromatography method in addition to stability studies for sequential estimation of remogliflozin etabonate, vildagliptin, and metformin HCl in tablet formulation.

Method: The mentioned method utilizes a Phenomenex Luna C18 column (250×4.6mm, 5μm). It consists of a column oven's temperature of 35°C. Mobile phase includes a mixture of 50% phosphate buffer (pH - 6.8) and 50% acetonitrile along with a flow rate of 0.8mL/min and 20minutes of run time. The injection volume was 20μL; 217nm is a detection wavelength, and a PDA detector is used for detection.

Results: The suggested technique was proven and validated per the ICH Q2 (R1) guideline. The combination was put under stress conditions that included acid, base, thermal, photolytic, and oxidative degradation. The combination was considerably degraded under oxidative, acidic, and basic circumstances for deterioration, and the degradation results were accurately identified from the observed peaks, demonstrating the method's effectiveness in detecting stability.

Conclusion: The technique was quick, precise, sensitive, and accurate; as a result, it may be used in quality control laboratories and the pharmaceutical industry for routine quality monitoring of tablets containing all three medications.

Medication errors are one of the causes of iatrogenic medication use in children. The POPI tool for detecting inappropriate drug prescriptions and prescription omissions in paediatrics was the first tool to be published in this field in 2014. Our aim was to update the POPI tool for French use based on current recommendations and practice. Criteria were removed, updated or added based on recommendations from learned societies and national bodies. The two-round Delphi method was used to reach a consensus of experts. The level of agreement of the healthcare professionals' proposals was rated on a 9-point Likert scale. In the first round, only proposals with a median agreement of 7 to 9 and an agreement of more than 65% were retained. In the second round, only those with a median agreement of 7 to 9 and over 75% agreement were retained. The POPI tool now includes eight categories (various, infectiology, gastroenterology, pneumonology, dermatology, neurology/pedopsychiatry, haematology and excipients). All the criteria were supported by bibliographical references. They were submitted to 20 French healthcare professionals: 9 pharmacists and 11 doctors (17 hospital-based and 3 self-employed). After two rounds of Delphi testing, 166 criteria were retained and validated (111 inappropriate prescriptions and 55 omissions). In conclusion, this study made it possible to update the POPI tool, which is still available for assessing paediatric prescriptions.

Objectives: Edaravone (EDR) is an effective neuroprotective agent in various neurological diseases; however, its use is restricted due to poor oral absorption. Bile salts are known for improving solubility and inhibiting drug crystallization in supersaturated conditions of the gastrointestinal tract (GIT). In our previous work, we prepared coamorphous dispersion (COAM) of EDR with sodium taurocholate (NaTC) using spray drying. The optimized EDR COAM exhibited superior in vitro performance compared to plain EDR. EDR is well absorbed in fasted-over-fed conditions.

Methods: The present work, we conducted a pharmacokinetic study for EDR and EDR COAM in fasted and fed conditions to check effect of food on its oral absorption. The LC-MS/MS-based method was developed and validated to determine the amount of EDR in plasma.

Results: The results suggested that EDR COAM did not show a significant difference in C_max (P=0.3544) and AUC (P=0.1696) of fasted and fed states. On the other hand, plain EDR showed 2-fold and 3-fold reduced C_max (P<0.0001) and AUC (P=0.0094) in the fed condition, respectively. The C_max and AUC of EDR COAM were improved in fasted (AUC: 2.56-fold) and fed states (AUC: 5.74-fold) than plain EDR, suggesting better oral absorption of COAM than crystalline EDR without having the effect of food.

Conclusions: The unique structural attributes of NaTC had the potential to inhibit the recrystallization of EDR in GIT, while concurrently reducing the impact of food on the oral absorption of EDR.

Objectives: This study aimed to investigate the protective activity of brown seaweed, the ethanolic and water extracts of Sargassum binderi (S. binderi) were examined. Anticancer drug, cisplatin is normally used for the treatment of solid tumors that cause acute kidney damage after assemblage in the renal tubules.

Material and methods: It was an acute nephrotoxicity study, animals were divided into several groups randomly, cisplatin (7mg/kg i.p.) and normal saline were used as positive and negative control respectively. The S. bindari ethanolic and water extract were given orally in a dose of 200mg/kg for 5days. Various biomarkers were assessed to observe the nephroprotective potential, while antioxidant activities were investigated using reduced glutathione, catalase and malondialdehyde as oxidative stress. GCMS was performed to validate the presence of important therapeutic moieties.

Results: The current result justified that pretreatment with S. binderi inhibited the elevation of antioxidant parameters and also showed protection against lipid peroxidation, induced by cisplatin challenge. The overall impact was the nephroprotection, which has been revealed from the results. GCMS evaluation of hexanes fraction revealed the presence of therapeutically important compounds including heptasiloxane, 3,7,11,15-tetramethyl-2-hexadecen-1-ol, hexadecamethyl, cyclooctasiloxane, and hexadecamethyl. These compounds have been reported for their antioxidant, antibacterial, anticancer, and antifungal activities.

Conclusion: S. binderi showed reno-protective effect by checking their well-known biochemical parameters probably due to the antioxidant activity as confirmed by the presence of compounds.
