A drug-resin liquid delayed-release suspension of pantoprazole sodium (PAZ-Na) was prepared to improve the effectiveness, convenience and safety of peptic ulcer treatment in children, the elderly and patients with dysphagia. Pantoprazole sodium drug-resin complexes (PAZ-Na-DRC) were prepared using the bath method. The fluidized bed coating method is used to coat it and then add excipients to make a dry suspension prepared before use. The parameters of the in vitro release experimental conditions were optimized and the drug release curve showed delayed release. Rats were given commercial PAZ-Na enteric-coated pellet capsules and the PAZ-Na delayed release suspension via intragastric administration. The results showed that the T of the PAZ-Na delayed release suspension was increased from 2h to 4h compared with the PAZ-Na enteric-coated pellet capsules. Similarly, the C was reduced from 6.162μg/mL to 3.244μg/mL with the concentration-time curve is very gentle compared with the commercial drug capsules. After oral administration, the relative bioavailability of PAZ-Na delayed release suspension (AUC of 19.578 μg•h•mL) compared with the commercial drug (AUC of 17.388 μg•h•mL) was 112.67%. The findings showed that the PAZ-Na delayed release suspension for oral administration was successfully formulated with highly improved pharmacokinetic indices.

Combination therapies using checkpoint inhibitors with immunostimulatory agonists have attracted great attention due to their synergistic therapeutic effects for cancer treatment. However, such combination immunotherapies require specific timing of doses to show sufficient antitumor efficacy. Sequential treatment usually requires multiple administrations of the individual drugs at specific time points, thus increasing the complexity of the drug regimen and compromising patient compliance.

Understanding clinical trajectories of sepsis patients is crucial for prognostication, resource planning, and to inform digital twin models of critical illness. This study aims to identify common clinical trajectories based on dynamic assessment of cardiorespiratory support using a validated electronic health record data that covers retrospective cohort of 19,177 patients with sepsis admitted to ICUs of Mayo Clinic Hospitals over eight-year period. Patient trajectories were modeled from ICU admission up to 14 days using an unsupervised machine learning two-stage clustering method based on cardiorespiratory support in ICU and hospital discharge status.

Diabetes significantly increases the risk of serious health issues, including prolonged skin inflammation and delayed wound healing, owing to inferior glucose control and suppression of the immune system. Although traditional hydrogen (H2) therapy is slightly effective, its ability to tailor the release of H2 on the skin is limited. Accordingly, this study proposed a novel strategy for electrocatalytic H2 release under neutral conditions to promote wound healing in diabetic mice and rabbit.

We report a 3-year-old patient with urethral cut injury and iatrogenic vesicovaginal fistula following a pelvic fracture; managed with Mitrofanoff procedure. Our patient presented with straining on urination with continuous colorless discharge on her diaper for the past 4 months. Investigations identified vesicovaginal fistulization making a definitive diagnosis of complete urethral injury.

The study presents two imported malaria cases with a history of travel to malaria-endemic areas and replied late response to treatment. In the blood preparations of the first case, dot-shaped nucleus structures were identified in the erythrocytes, which looked different from the classical erythrocytic forms. In the SD-Pf/Pan test, bands were obtained for both P.
