The ability of diaphragmatic excursion after extubation to predict the need for resumption of ventilatory support in critically ill surgical patients.

Background: This study evaluated the ability of diaphragmatic excursion (DE), measured 2 h after extubation, to predict the need for resumption of ventilatory support within 48 h in surgical critically ill patients.

Methods: This prospective observational study included adult surgical critically ill patients intubated for > 24 h and extubated after a successful spontaneous breathing trial. Sonographic measurement of the DE was performed 2 h after extubation.

Urolithin B as a renoprotective agent against 5-fluorouracil-induced nephrotoxicity: Role of Nrf2/Keap1/HO-1, SIRT1/FOXO3, and NF-кB/TNF-α signaling pathways.

The clinical use of 5-fluorouracil (5-FU) in cancer patients has been associated with nephrotoxicity, which is greatly curbing its therapeutic application. The pathogenesis of 5-FU-induced nephrotoxicity is complex; however, oxidative stress-mediated inflammation is considered a central pathogenic factor. Urolithin B (UB), a product of ellagitannins, has recently been assigned diverse pharmacological activities due to its potent antioxidant and anti-inflammatory properties.

Comparative study of midterm outcomes between Roux-en-Y gastric bypass (RYGB), diverted one-anastomosis gastric bypass (D-OAGB), and one anastomosis gastric bypass (OAGB).

Purpose: Diverted one anastomosis gastric bypass (D-OAGB) is a new procedure that entails performing Roux-en-Y diversion during OAGB to preclude post-OAGB bile reflux. This study aimed to compare the mid-term outcomes of Roux-en-Y gastric bypass (RYGB) and OAGB versus D-OAGB.

Methods: This is a retrospective study that encompassed the analysis of data from patients undergoing bypass surgeries from 2015 to May 2021.

Empagliflozin protects the heart from atrial fibrillation in rats through inhibiting the NF-κB/HIF-1α regulatory axis and atrial remodeling.

Atrial fibrillation (AF) is the most common form of sustained cardiac arrhythmia. The current study aimed to investigate the potential of empagliflozin (EMPA) to protect against acetylcholine (ACh)/calcium chloride (CaCl)-induced AF in rats and elucidate the possible underlying mechanism of action. Rats were randomly assigned to five groups, as follows: CTRL group: received 1 ml/kg isotonic saline; AF group: received 1 ml/kg induction mixture of ACh/CaCl (60 µg ACh and 10 mg CaCl per ml); EMPA group: received 30 mg/kg EMPA; AF + EMPA10 group: received the induction mixture concurrent with 10 mg/kg EMPA; AF + EMPA30 group: received the induction mixture concurrent with 30 mg/kg EMPA.

Sitagliptin synergizes 5-fluorouracil efficacy in colon cancer cells through MDR1-mediated flux impairment and down regulation of NFκB2 and p-AKT survival proteins.

5-fluorouracil (5-FU) is an inexpensive treatment for colon cancer; however, its efficacy is limited by chemoresistance. This study investigates the combination therapy approach of 5-FU with Sitagliptin (Sita), a diabetic drug with potential cancer-modulating effects. The combination was evaluated in vitro and in silico, focusing on the effects of Sita and 5-FU on colon cancer cells.
