OBJECTIVETo determine the effect of total parenteral nutrition (TPN)-induced hyperglycemia on hospital outcome.RESEARCH DESIGN AND METHODSThe study determined whether blood glucose values before, within 24 h, and during days 2–10 of TPN are predictive of hospital complications and mortality.RESULTSSubjects included a total of 276 patients receiving TPN for a mean duration of 15 ± 24 days (±SD). In multiple regression models adjusted for age, sex, and diabetes status, mortality was independently predicted by pre-TPN blood glucose of 121–150 mg/dl (odds ratio [OR] 2.2, 95% CI 1.1–4.4, P = 0.030), 151–180 mg/dl (3.41, 1.3–8.7, P = 0.01), and >180 mg/dl (2.2, 0.9–5.2, P = 0.077) and by blood glucose within 24 h of >180 mg/dl (2.8, 1.2–6.8, P = 0.020). A blood glucose within 24 h of >180 mg/dl was associated with increased risk of pneumonia (OR 3.1, 95% CI 1.4–7.1) and acute renal failure (2.3, 1.1–5.0).CONCLUSIONSHyperglycemia is associated with increased hospital complications and mortality in patients receiving TPN.

The present study demonstrated that racial disparities, highlighted by previous studies mainly in primary TKA, extend to influence revision TKA. Among the studied racial cohorts, race may affect outcomes and our results will help expand the current literature particularly on its role in revision TKA.
Antibiotic-loaded cement (ABLC) has been widely utilized as an adjuvant treatment for patients with periprosthetic joint infection (PJI) but has also evolved to play a prophylactic role against infection in primary total joint arthroplasties (TJA). Nevertheless, there is currently a paucity of studies that systematically investigated this concept. This review aimed at answering the following questions: (I) Can routine use of ABLC help reduce the current infection rates in primary TJA? (II) What are the risks associated with this approach? And (III) can routine use be justified in primary TJA from an economic standpoint? Multiple databases were queried including PubMed, EMBASE, EBSCO Host, and SCOPUS. Studies published between January 1, 1990 and March 31, 2018 were reviewed. Inclusion criteria were studies reporting: (I) clinical outcomes of routine use of ABLC in primary hip and knee arthroplasty with 2-year minimum follow-up, (II) complications related to the use of ABLC, (III) cost of using ABLC. The final analysis included 24 studies. Data from multiple studies demonstrate contradictory results for infection rates when ABLC is used in all primary procedures with a majority of studies showing similar infection rates between ABLC and plain cement. The main concerns associated with routine use of ABLC are negative effects on the mechanical stability of cement, possible systemic and local toxicity of the absorbed antibiotic, and development of resistant bacterial strains. However, current literature has not clinically validated these concerns. Lastly, with an estimated increase in 117 million dollars with the routine use of ABLC in only 50% of TJAs performed each year, it is difficult to justify the use of ABLC without clear superiority in reducing infection. The use of ABLC has undeniably changed the way orthopaedic surgeons deal with PJI today. However, the large-scale, prophylactic use of ABLC in primary TJAs requires further research and justification.
Purpose The outbreak of the SARS-CoV-2 virus has been associated with reports of increased anxiety, depression and fear among the general population. People with underlying psychiatric disorders are more susceptible to stress than the general population. The purpose of this study was to determine the prevalence of concomitant psychiatric conditions in the orthopaedic trauma population during the COVID-19 pandemic. Methods This retrospective cohort study evaluated orthopaedic trauma patients who received care at our institution between February through April of 2019 and February through April of 2020. Patient sex, age, mechanism of injury, associated injuries, fracture location, tobacco use, employment status, mental health diagnosis and presence of interpersonal violence were documented. Mental health diagnoses were defined based on International Classification of Diseases-10 classification. Results The study included 553 orthopaedic patients evaluated at our institution during the defined time period. Patients in the 2020 cohort had a higher prevalence of mental health diagnoses (26% vs. 43%, p < 0.0001) compared with the 2019 group. The odds ratio for mental health disorder in the 2020 patients was 2.21 (95% CI 1.54, 3.18) compared with the 2019 cohort. The 2020 cohort had a higher percentage of patients who reported interpersonal violence (20% vs. 11%, p = 0.005). Conclusion Our study showed a higher prevalence of psychiatric disease among orthopaedic trauma patients during the COVID-19 pandemic when compared with those seen during the same time of the year in 2019. Stress induced by the coronavirus pandemic can place patients with mental illness at a higher risk for perilous behaviours and subsequent fractures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
