Background: The study aimed to compare debridement, antibiotics, and implant retention (DAIR) vs. debridement antibiotic bead and retention of the implant (DABRI) in terms of infection-free success rate and treatment cost for acute periprosthetic joint infections after total knee arthroplasty (TKA).
Method: Between 2017 and 2020, 32 patients with acute periprosthetic joint infection who were treated by total knee arthroplasty were retrospectively reviewed. The patients were divided into a DAIR group (n=15) and a DABRI group (n=17). During the DABRI, additional calcium ulphate antibiotic beads were used. Patient age, the Musculoskeletal Infection Society score, microorganisms involved, and success rate were assessed.
Results: The mean age of DAIR group (n=15) was 69 years, with 7 being male, and 8 female. The mean follow-up period lasted 30 months. The success rate was 80% (12/15). The mean age of DABRI group (n=17) was 64 years, with 10 patients being male and 7 female. The mean follow-up period was 16 months. The success rate was 88% (15/17). There were no significant differences in patient age (P>0.05), the Musculoskeletal Infection Society score (P>0.05), and success rate (P>0.05). A significant difference was found in the follow-up period between the two groups (P<0.05).
Conclusion: Both DAIR and DABRI could be used to treat acute periprosthetic joint infections and the outcomes and treatment costs of the two procedures were comparable. Additional use of calcium sulfate beads was safe, but might not improve the treatment result. Randomized controlled studies are warranted for the routine use.

Intravenous versus intramuscular route of administration of natural adrenocorticotropic hormone in infantile epileptic spasm syndrome.
Transl Pediatr
December 2024
Department of Pediatrics, West China Second University Hospital, Sichuan University, Chengdu, China.
Background: Infantile epileptic spasm syndrome (ISS) is an age-dependent epileptic condition typically emerging within the first year of life, and adrenocorticotropic hormone (ACTH) has been established as a first-line therapeutic drug for the ISS since 1958. However, there is a notable variation in ACTH dosage practices worldwide, with intramuscular injection being common in some countries and intravenous drip preferred in others, including China. This study aimed to identify a preferable administration modality for ACTH-based utilization in treating ISS.

Obstetrics Department, Huzhou Maternity and Child Health Care Hospital Huzhou 313000, Zhejiang, China.
Objective: To investigate the effects of allylestrenol on sex hormone levels and delivery outcomes in women with threatened abortion.
Methods: This retrospective analysis examined clinical data of patients with threatened abortion treated at Huzhou Maternity & Child Health Care Hospital from January 1, 2021, to December 31, 2022. A total of 149 eligible patients were screened and divided into two groups: a control group (n=75) treated with progesterone capsules from January to December 2021, and an observation group (n=74) treated with allylestrenol from January to December 2022.

Department of Cardiology, The Second Affiliated Hospital of Nanchang University Nanchang 330006, Jiangxi, China.
Objective: To evaluate systematically the feasibility and effectiveness of His Bundle Pacing (HBP) for cardiac resynchronization therapy.
Methods: A comprehensive search was conducted in PubMed, EMbase, WOS, Cochrane Library, Medline, and SinoMed for studies published between December 2003 and December 2023. Primary clinical outcomes included implantation success, QRS wave duration, pacing threshold, left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), New York Heart Association (NYHA) cardiac function class, and complications.
