Objective: To evaluate the effect of NIPRD-AM1 on CYP3A4 in order to generate clinically significant data for its safe and efficacious use.
Materials And Methods: NIPRD-AM1 is a phytomedicine developed from aqueous root extracts of Nauclea latifolia Smith (Rubiaceae) for the treatment of uncomplicated malaria. The effect of NIPRD-AM1 on CYP3A4 was measured with and without the addition of NIPRD-AM1, by testing different concentrations of the product at 37 °C in reactive mixtures with ketoconazole (2.5 µM) as the positive control.
Results: RESULTS showed a very low IC50 value of 0.01 mg/ml similar to that of ketoconazole (0.016 mg/ml).
Conclusion: Metabolic processes of NIPRD-AM1 are likely to inhibit CYP3A4, with potential implication on drugs that are CYP3A4 substrates. This is a promising approach for guidance towards the safe and efficacious use of NIPRD-AM1.

This study aims to compare the efficacy of laparoscopic cholecystectomy combined with laparoscopic transcystic common bile duct exploration (LTCBDE), laparoscopic common bile duct exploration (LCBDE), and endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of gallbladder stones with common bile duct stones. We conducted a retrospective comparative analysis based on surgical time, intraoperative blood loss, postoperative recovery metrics, total hospitalization costs, gastrointestinal quality of life index (GIQLI) before and after surgery, and the incidence of postoperative complications. No significant differences were found among the three groups in terms of the surgical success rate, first stone clearance rate, intraoperative blood loss, incidence of postoperative complications, and stone recurrence rate (p > 0.

Introduction: Using non-medicinal oral contrast agents may aid safe delivery of magnetic resonance image-guided (MR-guided) radiotherapy by improving the ability to visualise and avoid excessive radiation dose to adjacent bowel/stomach. This scoping review aims to map the literature on non-medicinal oral contrasts used in upper-abdominal diagnostic or therapeutic magnetic resonance imaging (MRI) to find potential candidates for employing in MR-guided radiotherapy and identify gaps in knowledge for further study.
Methods: A scoping review of non-medicinal oral contrast used in upper-abdominal MRI research followed a pre-defined protocol based on Arksey and O'Malley's framework.

Immune checkpoint inhibitor (ICI) therapy is a cornerstone treatment for many cancers, but it can induce severe immunotoxicity, including acute interstitial nephritis (AIN). Currently, kidney biopsy is required to differentiate ICI-AIN from other causes of acute kidney injury (AKI). However, this invasive approach can lead to morbidity, delayed glucocorticoid treatment for patients with AIN, and unnecessarily prolonged suspension of ICI therapy in non-AIN patients.
