Debridement with antibiotics and implant retention (DAIR) is commonly utilized for prosthetic joint infection (PJI) for total knee arthroplasty (TKA); particularly in cases of acute PJI 1. Reported success rates of DAIR have been highly variable, but the overall success rate of DAIR cohort studies is ~70-80% 2. However, no large database studies have investigated the success rate of DAIR.

Unlabelled: Anellovirus infections are ubiquitous in mammals but lack any clear disease association, suggesting a commensal virus-host relationship. Although anelloviruses have been identified in numerous mammalian hosts, their presence in members of the family Delphinidae has yet to be reported. Here, using a metagenomic approach, we characterize complete anellovirus genomes ( = 69) from four Delphinidae host species: short-finned pilot whale (, = 19), killer whale (, = 9), false killer whale (, = 6), and pantropical spotted dolphin (, = 1).

Introduction: Readmission within 90 days of total joint arthroplasty (TJA) via an emergency department (ED) encounter represents a significant economic burden to the healthcare system. We aimed to determine the utility of a previously described readmission risk assessment tool (RRAT) in predicting readmission after presentation to the ED within 90 days of primary TJA.

Methods: At a single academic tertiary referral medical center, a retrospective chart review was used to collect demographic data, surgery type, medical history, reason for presentation in the ED, and ED disposition for the 1,576 patients who underwent TJA between April 1, 2016, and December 31, 2018.

Background: Despite their effectiveness in postoperative analgesia regimens for total knee arthroplasty (TKA) and total hip arthroplasty (THA), opioid medications are accompanied by well-known side effects and a risk of long-term dependence. These drawbacks have prompted the exploration of opioid-free analgesia protocols. The purpose of this study was to summarize the nature and extent of evidence available on opioid-free analgesia protocols in THA and TKA management.

Apremilast is a relatively new oral treatment for psoriasis, which reduces expression of pro-inflammatory factors, including tumour necrosis factor-α (TNFα), critical to the immune control of Mycobacterium tuberculosis infection. In randomised controlled trials (RCTs) for apremilast no new cases of active tuberculosis (TB) were identified, thus, screening for latent TB infection (LTBI) is not currently recommended prior to apremilast initiation. We describe a case of M.

Article Synopsis
  • Patellofemoral arthroplasty is a surgical option for patients with isolated patellofemoral arthritis after nonoperative treatments fail, aiming to relieve pain while preserving natural knee movement.
  • The procedure involves using a robotic surgical system (MAKO) to carefully plan and execute several steps including bone resection and implant placement based on preoperative imaging.
  • Alternatives to this surgery include various nonoperative methods and other surgical options, but patellofemoral arthroplasty may be preferred for its effectiveness and preservation of bone stock compared to total knee arthroplasty.

The identification and targeting of B-cell maturation antigen (BCMA) through immunotherapeutic strategies such as antibody-drug conjugates, chimeric antigen receptor T cells, and T-cell engagers have revolutionized the care of patients with multiple myeloma (MM). These treatment modalities have improved the survival outcomes of patients with relapsed and/or refractory MM compared with previously established strategies and are moving into earlier lines of therapy. Despite their efficacy, the majority of patients eventually relapse, necessitating additional therapeutic targets for salvage.

Vertebrate body axis formation initiates during gastrulation and continues within the tail bud at the posterior end of the embryo. Major structures in the trunk are paired somites, which generate the musculoskeletal system, the spinal cord-forming part of the central nervous system, and the notochord, with important patterning functions. The specification of these different cell lineages by key signalling pathways and transcription factors is essential, however, a global map of cell types and expressed genes in the avian trunk is missing.

Bacterial cell division is crucial for replication and requires careful coordination via proteins collectively called the divisome. The tubulin-like GTPase FtsZ is the master regulator of this process and serves to recruit downstream divisome proteins and regulate their activities. Upon assembling at mid-cell, FtsZ exhibits treadmilling motion driven by GTP binding and hydrolysis.
