Introduction: The development of new prostheses with improved osseointegration, bone preservation, and reduced cost has renewed interest in uncemented total knee arthroplasty (UCTKA). In the current study, we aimed to: (1) assess demographic data of patients who were and were not readmitted and (2) identify patient-specific risk factors associated with readmission. Methods: A retrospective query from the PearlDiver database was performed from January 1, 2015, to October 31, 2020. International Classification of Disease, Ninth Revision (ICD-9), ICD-10, or Current Procedural Terminology (CPT) coding was used to distinguish cohorts of patients who had osteoarthritis of the knee and underwent UCTKA. Patients readmitted within 90 days were classified as the study population, while those who were not readmitted were classified as control. A linear regression model was utilized to analyze readmission risk factors. Results: The query yielded 14,575 patients, with 986 (6.8%) being readmitted. Patient demographics such as age (P < 0.0001), sex (P < 0.009), and comorbidity (P < 0.0001) were associated with annual 90-day readmission. Patient-specific risk factors associated with 90-day readmission following press-fit total knee arthroplasty were: arrhythmia (OR: 1.29, 95% CI: 1.11–1.49, P < 0.0005), coagulopathy (OR: 1.36, 95% CI: 1.13–1.63, P < 0.0007), fluid and electrolyte abnormalities (OR: 1.59, 95% CI: 1.38–1.84, P < 0.0001), iron deficiency anemia (OR: 1.49, 95% CI: 1.27–1.73, P < 0.0001), and obesity (OR: 1.37, 95% CI: 1.18–1.60, P < 0.0001). Discussion: This study demonstrates that patients with comorbidities, such as fluid and electrolyte problems, iron deficiency anemia, and obesity, were at an increased risk of readmission after having an uncemented total knee replacement. The risks of readmission following an uncemented total knee arthroplasty can be discussed with patients who have certain comorbidities by arthroplasty surgeons. [ABSTRACT FROM AUTHOR]

The article discusses the ethnic identity of the first settlers of the town of New Paltz in Ulster County, New York, traditionally identified since the 19th century as Huguenots, but referred to in various contemporaneous 17th-century documents as Walloons. The origins of the New Paltz settlers, including Louis DuBois, in the French-speaking region of the Spanish Netherlands (today northern France and the southern Belgium) is discussed, as is their religious background as Dutch Calvinists who emigrated to the Dutch colony of New Netherland in the 1660s to escape Catholic persecution. Ethnic relations in the New Paltz settlement are also discussed.

Background: Elevated Metrorail systems differ from conventional trains by their slower speeds and collisions with pedestrians predominantly occurring at accessible stations or platforms. Here, the orthopedic implications of pedestrians struck by a Metrorail are evaluated, as were the correlations of substance abuse and psychiatric history on injury and death., Methods: Retrospective cohort study at a single Level-1 trauma center of patients requiring admission with orthopedic injuries following Metrorail impact from 1/2004-2/2017. Demographics, substance abuse, psychiatric history, intentionality, LOS, follow-up, fracture characteristics, and management were studied., Results: 33 patients sustained 104 total orthopedic injuries requiring admission; nine sustained 15 traumatic amputations. There were at least 37 open fractures, with some incomplete data in deceased (5) and amputation (9) patients. Suicide attempts were completed at 35.7% and were associated with a documented psychiatric illness and prior psychiatric evaluation. Spine injuries were associated with increased traumatic brain injuries, rib fractures, and open pelvic ring injuries, yet fewer humerus fractures. Open fractures were significantly predictive of death. 14 patients (42.4%) required ICU admission, and 26 (78.8%) patients required orthopaedic surgery (mean 1.3 ± 1.4 operations)., Conclusions: Metrorail systems are unique sources of orthopaedic injuries requiring high rates of critical care and surgical intervention. Patients sustain multiple injuries, many with amputations. With this mechanism, there is a high rate of open fractures and suicide. Trauma centers should emphasize an extensive evaluation of orthopaedic injuries in this patient setting. Level of Evidence: II., Competing Interests: Disclosures: The authors report no potential conflicts of interest related to this study.
