AI Article Synopsis

  • Post-traumatic osteoarthritis patients undergoing conversion total knee arthroplasty (TKA) show higher rates of surgical site complications and 90-day readmissions compared to those with soft-tissue injuries.
  • A study of 72 conversion TKA cases indicated that early complications were significantly more common in the post-fracture cohort (22% vs 4.4%) and the 90-day readmission rate was also higher (14.8% vs 2.2%).
  • Patients with multiple prior knee surgeries tended to be younger and received more expensive implants, while those with previous open reduction internal fixations faced more complications than those with prior arthroscopies.

Article Abstract

Background: Compared to total knee arthroplasty (TKA) for primary osteoarthritis, conversion TKAs in the post-traumatic setting are associated with increased operative times, infection rates, and readmissions. We aim at determining how post-traumatic osteoarthritis and previous knee surgery influence postoperative outcomes in conversion TKA.

Methods: Seventy-two conversion TKA procedures with prior knee trauma at a single institution between April 2012 and 2016 were examined. Twenty-seven (37.5%) cases had a preoperative site-specific diagnosis such as fracture of the proximal tibia, distal femur, or patella whereas 45 (62.5%) cases had a preoperative diagnosis of significant soft-tissue trauma. These 2 groups were compared in terms of total implant cost, length of stay, complications, and readmission and reoperation rates. A subanalysis was conducted to evaluate the effects of previous knee surgery on surgical outcomes.

Results: The postfracture TKA cohort suffered significantly higher early surgical site complications (22% vs 4.4%, P = .02) and 90-day readmissions (14.8% vs 2.2%, P = .042) compared to the soft-tissue trauma cohort. Operative time, total implant costs, length of stay, medical complications, 30-day readmissions, and 90-day reoperation rates did not significantly differ. It was also found that patients with multiple prior knee surgeries compared to one prior knee surgery are younger (53.0 vs 63.1, P = .003), healthier, and receive significantly more expensive implants (1.72 vs 1.07, P = .026). In addition, patients with previous open reduction internal fixations experience more surgical site complications than patients with previous arthroscopies (31% vs 3.3%, P = .042).

Conclusion: Patients with previous site-specific fracture are more likely to experience surgical site complications and 90-day readmissions after conversion TKA than patients with previous soft-tissue knee trauma. Multiple previous knee surgeries appear to serve as an independent factor in the selection of costlier implants irrespective of preoperative diagnosis.

Background: Abnormal results in commonly used primary care blood tests could be early markers of cancer in patients presenting with non-specific abdominal symptoms.

Methods: Using linked data from the UK Clinical Practice Research Datalink (CPRD) and national cancer registry we compared blood test use and abnormal results from the 24-months pre-diagnosis in 10,575 cancer patients (any site), and 52,875 matched-controls aged ≥30 presenting, with abdominal pain or bloating to primary care.

Results: Cancer patients had two-fold increased odds of having a blood test (odds ratio(OR):1.

Spirituality care plays an important role in holistic healthcare. Our previous study found Muslim psychiatric inpatients encounter significant obstacles that hinder their ability to engage in a formal prayer practice in the hospital. To address this gap, we aimed to develop a spirituality and religious needs inventory specifically for Muslim psychiatric inpatients.

Given the heterogeneity of acute myeloid leukemia patients, it is necessary to identify patients considered fit for intensive therapy but who will perform poorly, and in whom alternative approaches deserve investigation. We analyzed 1034 fit adults ≤70 years intensively treated between 2012 and 2022 in the CETLAM group. Young adults ( ≤ 60 years) presented higher remission rates and improved survival than older adults above that age (CR 79% vs.

  • FT596 is a novel cancer therapy using iPSC-derived CAR NK cells targeting CD19, designed to assess its safe dosage and effectiveness alone and with rituximab in patients with B-cell lymphoma.
  • This phase 1 trial involved patients with relapsed or refractory B-cell lymphoma, administering FT596 after chemotherapy, with separate regimens for those receiving rituximab and those who did not.
  • The study measured potential side effects while determining the optimal dose of FT596 and allowed modifications to the treatment based on patient tolerance and response.
