Role of insulin-dependent and non-insulin-dependent diabetes in aseptic revision total shoulder arthroplasty.

PURPOSE: This study investigates the association between insulin-dependent and non-insulin-dependent diabetes and 30-day postoperative complications following aseptic revision total shoulder arthroplasty (TSA). METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent aseptic revision TSA from 2015 to 2021. The study population was divided into three groups based on diabetic status: nondiabetes, insulin-dependent diabetes, and non-insulin-dependent diabetes. Logistic regression analysis was conducted to investigate the relationship between diabetic status and postoperative complications. RESULTS: Compared to nondiabetes, insulin-dependent diabetes was independently associated with a significantly greater likelihood of experiencing any complication (OR 1.59, 95% CI 1.08-2.35; P = 0.020) and LOS > 2 days (OR 1.73, 95% CI 1.13-2.65; P = 0.012). Compared to nondiabetes, non-insulin-dependent diabetes was not independently associated with a significantly greater likelihood of experiencing complications. Preoperative insulin-dependent diabetic status was significantly associated with a greater rate of early postoperative complications following aseptic revision TSA, while preoperative non-insulin-dependent diabetic status was not. CONCLUSION: Preoperative insulin-dependent diabetic status was significantly associated with a greater rate of early postoperative complications following aseptic revision TSA. A better understanding of the role diabetes, both insulin-dependent and non-insulin-dependent, as a risk factor may help physicians better risk stratify and select surgical candidates for revision TSA.

Elevated alkaline phosphatase independently predicts early postoperative complications in noninfectious revision total shoulder arthroplasty.

PURPOSE: This study investigates the association between preoperative serum alkaline phosphatase levels and 30 day postoperative complications following noninfectious revision total shoulder arthroplasty (TSA). We hypothesize that elevated alkaline phosphatase levels are significantly associated with an increased 30 day postoperative complication rate. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent noninfectious revision TSA from 2015 to 2022. The study population was divided into two groups based on preoperative serum alkaline phosphatase: normal (44-147 IU/L) and elevated (> 147 IU/L). Logistic regression analysis was conducted to investigate the relationship between elevated alkaline phosphatase levels and postoperative complications. RESULTS: Compared to normal levels, elevated alkaline phosphatase was independently associated with a significantly greater likelihood of experiencing any complications (odds ratio [OR] 2.54, 95% confidence interval [CI] 1.41-4.55; P = .002), sepsis (OR 9.96, 95% CI 1.67-59.29; P = .012), blood transfusions (OR 3.77, 95% CI 1.48-9.61; P = .005), readmission (OR 3.65, 95% CI 1.48-9.01; P = .005), and length of stay > 2 days (OR 2.37, 95% CI 1.31-4.30; P = .004). CONCLUSIONS: Elevated preoperative alkaline phosphatase was associated with a greater rate of early postoperative complications following noninfectious revision TSA. LEVEL OF EVIDENCE: Level III; Retrospective Cohort Comparison; Prognosis Study.

Postoperative complications associated with congestive heart failure in aseptic revision total shoulder arthroplasty.

PURPOSE: The aim of this study is to explore potential complications and risk factors associated with revision TSA in patients with congestive heart failure (CHF). METHODS: This study examined all individuals who underwent revision total shoulder arthroplasty (TSA) from 2015 to 2022, sourced from the American College of Surgeons National Surgical Quality Improvement database. The analysis encompassed patient demographics, comorbidities, and 30-day postoperative complications. Logistic regression was employed to analyze the postoperative complications linked to patients with preoperative CHF. RESULTS: Compared to patients without CHF, patients with CHF were significantly associated with dependent functional status (P < .001), chronic obstructive pulmonary disease (P < .001), and hypertension (P = .002). Compared to patients without CHF, patients with CHF were independently associated with a significantly greater likelihood of experiencing any complication (OR 2.19, 95% CI 1.12-4.29; P = .022) and non-home discharge (OR 3.02, 95% CI 1.37-6.65; P = .006). CONCLUSION: Congestive heart failure was identified as an independent risk factor for experiencing any complication and non-home discharge in patients undergoing revision TSA. Awareness of the cardiovascular health status of a patient and its severity can influence the decision-making process when considering revision TSA. LEVEL OF EVIDENCE III: Retrospective Cohort Comparison Using Large Database; Prognosis Study.

Midterm Outcomes of Endovascular Versus Open Surgical Repair of Intact Descending Thoracic Aneurysms in Patients with Connective Tissue Disorders.

BACKGROUND: Data on the efficacy of endovascular thoracic endovascular aneurysm repair (TEVAR) versus open surgical repair for chronic aortic pathology in patients with connective tissue disorders are limited. In particular, few studies have examined outcomes of TEVAR versus open repair for intact descending thoracic aortic aneurysms (DTAA) in this subset of patients beyond index hospitalization. Therefore, we investigate 5-year outcomes of TEVAR and open surgical repair of intact DTAAs in patients with known connective tissue disorders. METHODS: Using the TriNetX Data Network, a global federated database of over 75 million patients, we conducted a retrospective cohort study of patients with connective tissue disorders and intact DTAAs, treated initially with either TEVAR or open surgery. Eligible patients were 1:1 propensity score-matched for several preoperative co-variates including demographics, surgical history, and comorbidities. We calculated and compared 5-year cumulative incidence and hazards of death, re-intervention, aortic dissection, renal failure, stroke, intracranial hemorrhage, paraplegia, and limb ischemia using the Kaplan-Meier method and Cox proportional hazards models. RESULTS: We identified 55 patients treated with TEVAR and 200 treated with open surgery. After matching, we compared 46 patients in each cohort. After matching, only incidence of re-intervention via endovascular approach was significantly higher among patients in the TEVAR cohort (27.1% vs. 4.8%, P = 0.009). Rates and hazards of other outcomes were higher in the TEVAR group, however, differences were not statistically significant. CONCLUSIONS: Patients treated with TEVAR had numerically higher rates of adverse outcomes compared to open surgical patients, however only the difference in re-intervention rate was statistically significant. Given the evolving landscape of endovascular intervention, greater-powered studies are needed to determine the safety and efficacy of TEVAR for intact DTAAs in a select subset of connective tissue disorder patients.

Oxycodone in the Opioid Epidemic: High 'Liking', 'Wanting', and Abuse Liability.

It is estimated that nearly a third of people who abuse drugs started with prescription opioid medicines. Approximately, 11.5 million Americans used prescription drugs recreationally in 2016, and in 2018, 46,802 Americans died as the result of an opioid overdose, including prescription opioids, heroin, and illicitly manufactured fentanyl (National Institutes on Drug Abuse (2020) Opioid Overdose Crisis. https://www.drugabuse.gov/drugs-abuse/opioids/opioid-overdose-crisis . Accessed 06 June 2020). Yet physicians will continue to prescribe oral opioids for moderate-to-severe pain in the absence of alternative therapeutics, underscoring the importance in understanding how drug choice can influence detrimental outcomes. One of the opioid prescription medications that led to this crisis is oxycodone, where misuse of this drug has been rampant. Being one of the most highly prescribed opioid medications for treating moderate-to-severe pain as reflected in the skyrocketed increase in retail sales of 866% between 1997 and 2007, oxycodone was initially suggested to be less addictive than morphine. The false-claimed non-addictive formulation of oxycodone, OxyContin, further contributed to the opioid crisis. Abuse was often carried out by crushing the pills for immediate burst release, typically by nasal insufflation, or by liquefying the pills for intravenous injection. Here, we review oxycodone pharmacology and abuse liability as well as present the hypothesis that oxycodone may exhibit a unique pharmacology that contributes to its high likability and abuse susceptibility. We will discuss various mechanisms that likely contribute to the high abuse rate of oxycodone including clinical drug likability, pharmacokinetics, pharmacodynamics, differences in its actions within mesolimbic reward circuity compared to other opioids, and the possibility of differential molecular and cellular receptor interactions that contribute to its selective effects. We will also discuss marketing strategies and drug difference that likely contributes to the oxycodone opioid use disorders and addiction.

The role of hypertensive status in the preoperative patient selection of TSA.

Background: This study investigates the relationship between hypertension and postoperative complications following total shoulder arthroplasty (TSA). Methods: All patients who underwent TSA between 2015 and 2020 from the American College of Surgeons National Surgical Quality Improvement database were surveyed. The study population was divided into patients with no hypertension and patients with hypertension. Patient demographics, comorbidities, and 30-day postoperative complications were collected. Logistic regression analysis was used to investigate the relationship between hypertension and postoperative complications. Results: Compared to no hypertension, hypertension was significantly associated with an increased likelihood of experiencing sepsis (P = .021), pneumonia (P = .019), myocardial infarction (P = .038), blood transfusions (P = .006), readmission (P < .001), reoperation (P < .001), non-home discharge (P < .001), and any complication (P < .001). After accounting for significant patient variables, compared to no hypertension, hypertension was independently significantly associated with an increased likelihood of experiencing reoperation (odds ratio 1.48; 95% CI, 1.142-1.905; P = .003) and any complication (odds ratio 1.10; 95% CI, 1.008-1.205; P = .033). Conclusion: In this study, we identified hypertension as an independent significant predictor for both reoperation and any complication following TSA. This study provides evidence for incorporating a patient's hypertensive status into preoperative screening, aiming to improve surgical candidate selection and surgical outcomes following TSA.

Preoperative thrombocytopenia and thrombocytosis predict complications after arthroscopic rotator cuff repair.

Background: The purpose of this study was to investigate the association between preoperative platelet count and 30-day postoperative complications following arthroscopic rotator cuff repair (aRCR). Methods: The American College of Surgeons National Surgical Quality Improvement database was queried for all patients who underwent aRCR between 2015 and 2021. The study population was divided into 5 groups based on preoperative platelet count: normal (200-450k, reference cohort), low-normal (150-200k), mild thrombocytopenia (100-150k), moderate-to-severe thrombocytopenia (<100k), and thrombocytosis (>450k). Thirty-day postoperative complications following aRCR were collected. Multivariate logistic regression analysis was conducted to investigate the relationship between preoperative platelet counts and postoperative complications. Results: 24,779 patients were included in this study: 18,697 (75.5%) in the normal group, 4730 (19.1%) in the low-normal group, 1012 (4.1%) in the mild thrombocytopenia group, 171 (0.7%) in the moderate-to-severe thrombocytopenia group, and 169 (0.7%) in the thrombocytosis group. Low-normal platelets were an independent predictor of urinary tract infection (odds ratio [OR] 2.06, 95% confidence interval [CI] 1.12-3.77; P = .020). Mild thrombocytopenia was not an independent predictor of any complications. Moderate-to-severe thrombocytopenia was an independent predictor of sepsis (OR 9.39, 95% CI 1.48-59.47; P = .017), pneumonia (OR 6.62, 95% CI 1.32-33.24; P = .022), and nonhome discharge (OR 3.34, 95% CI 1.20-9.25; P = .021). Thrombocytosis was an independent predictor of urinary tract infection (OR 4.91, 95% CI 1.16-20.78; P = .030). Conclusion: Abnormal preoperative platelet counts, both low and high, were independent risk factors for 30-day postoperative complications following aRCR.

Six-Item Modified Frailty Index independently predicts complications following total shoulder arthroplasty.

Background: In the realm of orthopedic surgery, frailty has been associated with higher rates of complications following total hip and total knee arthroplasties. Among various measures of frailty, the Six-Item Modified Frailty Index (MF-6) has recently gained popularity as a predictor for postoperative complications. The purpose of this study was to investigate MF-6 as a predictor for early postoperative complications in the elderly patient population following total shoulder arthroplasty (TSA). Methods: The authors queried the American College of Surgeons National Surgical Quality Improvement Program database for all patients who underwent TSA between 2015 and 2020. Patient demographics and comorbidities were compared between cohorts using bivariate logistic regression analysis. Multivariate logistic regression, adjusted for all significantly associated patient demographics and comorbidities, was used to identify associations between the MF-6 score and postoperative complications. Results: Of total, 9228 patients were included in this study: 8764 (95.0%) had MF-6 <3, and 464 (5.0%) patients had MF-6 ≥3. Multivariate analysis found MF-6 ≥3 to be independently associated with higher rates of urinary tract infection (odds ratio [OR]: 2.79, 95% confidence interval [CI]: 1.49-5.23; P = .001), blood transfusion (OR: 1.53, 95% CI: 1.01-2.32; P = .045), readmission (OR: 1.58, 95% CI: 1.06-2.35; P = .024), and non-home discharge (OR: 2.60, 95% CI: 2.08-3.25; P < .001). Conclusion: A high MF-6 score (≥3) in patients aged 65 and older is independently associated with higher rates of urinary tract infection, blood transfusion, readmission, and non-home discharge following TSA. The MF-6 score can be easily calculated preoperatively and may allow for better preoperative risk stratification.

Shoulder arthroscopy in elderly patients: malnutrition and early postoperative outcomes.

Background: This study investigates the association between the Geriatric Nutritional Risk Index (GNRI), a simple, readily available malnutrition risk index, and 30-day postoperative complications following shoulder arthroscopy. Methods: The American College of Surgeons National Surgical Quality Improvement Program database was used to identify all patients aged ≥65 years who underwent shoulder arthroscopy between 2015 and 2021. The study population was indexed into 3 cohorts of preoperative GNRI: normal/reference (GNRI >98), moderate malnutrition (92≤ GNRI ≤98), and severe malnutrition (GNRI <92). Multivariate logistic regression analysis was conducted to investigate the connection between preoperative GNRI and postoperative complications. Results: Severe malnutrition was independently significantly associated with a greater likelihood of any complication (odds ratio [OR]: 11.70, 95% confidence interval [CI]: 8.58-15.94; P < .001), sepsis (OR: 26.61, 95% CI: 10.86-65.21; P < .001), septic shock (OR: 7.53, 95% CI: 1.56-36.32; P = .012), blood transfusions (OR: 25.38, 95% CI: 6.40-100.59; P < .001), pulmonary embolism (OR: 7.25, 95% CI: 1.27-41.40; P = .026), surgical site infection (OR: 22.08, 95% CI: 7.51-64.97; P < .001), nonhome discharge (OR: 15.75, 95% CI: 9.83-25.23; P < .001), readmission (OR: 2.69, 95% CI: 1.52-4.74; P < .001), unplanned reoperation (OR: 6.32, 95% CI: 2.23-17.92; P < .001), length of stay >2 days (OR: 23.66, 95% CI: 16.25-34.45; P < .001), and mortality (OR: 14.25, 95% CI: 2.89-70.40; P = .001). Conclusion: GNRI-based malnutrition is strongly predictive of perioperative complications following shoulder arthroscopy in geriatric patients and has utility as an adjunctive risk stratification tool.

The geriatric nutritional risk index as a strong predictor of adverse outcomes following total shoulder arthroplasty.

Background: This study investigates the association between the Geriatric Nutritional Risk Index (GNRI), a simple readily available measure of malnutrition risk, and 30-day postoperative complications following total shoulder arthroplasty (TSA). Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent TSA between 2015 and 2021. The study population was divided into 3 groups based on preoperative GNRI: normal/reference (GNRI > 98), moderate malnutrition (92 ≤ GNRI ≤ 98), and severe malnutrition (GNRI < 92). Logistic regression analysis was conducted to investigate the connection between preoperative GNRI and postoperative complications. Results: Compared to normal nutrition, moderate malnutrition was independently significantly associated with a greater likelihood of any complications (odds ratio [OR]: 1.74, 95% confidence interval [CI]: 1.54-1.96; P < .001), blood transfusions (OR: 1.52, 95% CI: 1.09-2.11; P = .013), failure to wean off a ventilator within 48 hours (OR: 3.84, 95% CI: 1.26-11.72; P = .018), wound dehiscence (OR: 15.80, 95% CI: 1.61-155.28; P = .018), nonhome discharge (OR: 1.90, 95% CI: 1.63-2.22; P < .001), readmission (OR: 1.54, 95% CI: 1.19-1.99; P = .001), unplanned reoperation (OR: 1.87, 95% CI: 1.27-2.74; P = .001), length of stay > 2 days (OR: 1.85, 95% CI: 1.63-2.12; P < .001), and mortality (OR: 3.38, 95% CI: 1.32-8.71; P = .011). Severe malnutrition was independently significantly associated with a greater likelihood of any complication (OR: 3.33, 95% CI: 2.80-3.97; P < .001), sepsis (OR: 9.83, 95% CI: 2.94-32.85; P < .001), pneumonia (OR: 3.30, 95% CI: 1.71-6.38; P < .001), unplanned reintubation (OR: 5.77, 95% CI: 2.47-13.51; P < .001), urinary tract infection (OR: 2.15, 95% CI: 1.19-3.87; P = .011), stroke (OR: 3.57, 95% CI: 1.18-10.84; P = .024), blood transfusions (OR: 5.27, 95% CI: 3.86-7.20; P < .001), failure to wean off a ventilator within 48 hours (OR: 7.64, 95% CI: 2.29-25.55; P < .001), Clostridioides difficile infection (OR: 4.17, 95% CI: 1.21-14.32; P = .023), nonhome discharge (OR: 3.56, 95% CI: 2.92-4.34; P < .001), readmission (OR: 2.05, 95% CI: 1.46-2.89; P < .001), length of stay > 2 days (OR: 3.27, 95% CI: 2.73-3.92; P < .001), and mortality (OR: 4.61, 95% CI: 1.51-14.04; P = .007). Conclusion: Malnutrition based on GNRI is a strong predictor of complications following TSA, with increasing severity related to an increased rate of complications.

Aspartate Aminotransferase-to-Platelet Ratio Index Suggestive of Liver Dysfunction Predicts Early Complications After Open Reduction Internal Fixation of Distal Radius Fractures.

Purpose: Aspartate aminotransferase-to-platelet ratio index (APRI) is a cost-effective and noninvasive measure of liver function, an alternative to the gold standard liver biopsy, which is resource-intensive and invasive. The purpose of this study was to investigate the association between preoperative APRI and 30-day postoperative complications after isolated open reduction internal fixation (ORIF) of distal radius fractures (DRFs). Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent isolated ORIF of DRFs between 2015 and 2021. The study population was divided into two groups on the basis of preoperative APRI: normal/reference (APRI, <0.5) and liver dysfunction (APRI, ≥0.5). Information on patient demographics, comorbidities, and 30-day postoperative complications after isolated ORIF of DRFs was collected. Multivariate logistic regression analysis was performed to investigate the relationship between preoperative APRI and postoperative complications. Results: Compared to patients with normal APRI, patients with preoperative APRI associated with liver dysfunction were significant for male sex (P < .001), younger age (P < .001), American Society of Anesthesiologists classification grade ≥3 (P < .001), being smokers (P < .001), and having comorbid diabetes (P = .002) and bleeding disorders (P < .001). Preoperative APRI associated with liver dysfunction was independently associated with a greater likelihood of any complications (odds ratio [OR], 1.49; 95% confidence interval [CI], 1.19-1.87; P < .001), nonhome discharge (OR, 1.62; 95% CI, 1.15-2.27; P = .005), and a length of stay of >2 days (OR, 1.70; 95% CI, 1.32-2.20; P < .001). Conclusions: Aspartate aminotransferase-to-platelet ratio index values associated with liver dysfunction were associated with an increased rate of early postoperative complications after DRF ORIF. Clinical relevance: This study suggests APRI's utility as a cost-effective, noninvasive measure of liver function that physicians can use before surgery to better identify surgical candidates with DRFs and suspicion of liver dysfunction. Type of study/level of evidence: Prognostic III.

Preoperative Risk Stratification in Arthroscopic Rotator Cuff Repair: Aspartate Aminotransferase-to-Platelet Ratio Index as an Estimate of Liver Dysfunction.

BACKGROUND: Aspartate Aminotransferase-to-Platelet Ratio Index (APRI) is a cost-effective and noninvasive measure of liver function, an alternative to the gold standard liver biopsy which is resource-intensive and invasive. This study investigates the association between various degrees of liver dysfunction based on APRI and 30-day postoperative complications following arthroscopic rotator cuff repair (aRCR). METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent aRCR between 2015 and 2021. The study population was divided into four groups based on preoperative APRI: normal/reference (APRI ≤ 0.5), mild fibrosis (0.5 < APRI ≤ 0.7), significant fibrosis (0.7 < APRI ≤ 1), and cirrhosis (APRI > 1). Multivariate logistic regression analysis was conducted to investigate the connection between preoperative APRI and postoperative complications. RESULTS: Compared to normal liver function, mild fibrosis was significantly associated with male gender, lower BMI, American Society of Anesthesiologists (ASA) classification ≥ 3, and comorbid diabetes, hypertension, chronic obstructive pulmonary disease, and bleeding disorders. Significant fibrosis was significantly associated with male gender, greater BMI, ASA classification ≥ 3, and comorbid diabetes, hypertension, and bleeding disorders. Cirrhosis was significantly associated with younger age, ASA classification ≥ 3, smokers, and comorbid diabetes and bleeding disorders. Compared to normal liver function, fibrosis was not associated with complications, significant fibrosis was associated with myocardial infarction, and cirrhosis was associated with major complications, sepsis, non-home discharge, and mortality. However, mild fibrosis, significant fibrosis, and cirrhosis were independently associated with any adverse 30-day postoperative complications following aRCR. CONCLUSION: Among those with predicted liver damage based on preoperative APRI, 30-day postoperative complications following aRCR were not found to be independently associated with preoperative mild fibrosis, significant fibrosis, or cirrhosis. Our results suggest that APRI predictive of liver dysfunction may be a weaker deterrent to undergoing aRCR compared to other orthopedic surgeries.

Hypertension and postoperative complications following arthroscopic rotator cuff repair.

Background: The purpose of this study was to investigate the relationship between hypertension and postoperative complications following arthroscopic rotator cuff repair (aRCR). Methods: The American College of Surgeons National Surgical Quality Improvement Program database was surveyed for all patients who underwent aRCR between 2015 and 2021. Patient demographics, comorbidities, and 30-day postoperative complication data were analyzed. Multivariate logistic regression identified postoperative complications associated with hypertension. Results: Forty-six thousand five hundred and sixty-two patients were included in the analysis: 20,999 (45.1%) patients in the hypertensive cohort and 25,563 (54.9%) in the nonhypertensive cohort. Hypertension was associated with male gender (P < .001), age ≥ 65 years (P < .001), body mass index > 30 (P < .001), dependent functional status (P < .001), American Society of Anesthesiologists classification ≥ 3 (P < .001), current smoker (P < .001), diabetes (P < .001), chronic obstructive pulmonary disease (P < .001), and bleeding disorders (P < .001). Thrity-day postoperative complications significantly associated with hypertension included pneumonia (P = .012), reintubation (P = .009), urinary tract infection (P = .002), stroke (P = .044), myocardial infarction (P = .004), ventilator > 48 hours (P = .017), readmission (P < .001), non-home discharge (P < .001), and mortality (P = .020). After adjusting for patient demographics and comorbidities, readmission (odds ratio [OR] 1.41; 95% confidence interval [CI] 1.13-1.75; P = .002) was independently associated with hypertension. Conclusion: Hypertension was identified as a risk factor for various postoperative complications following aRCR. Hypertension was found to be an independent predictor for readmission following aRCR.

Increased preoperative aspartate aminotransferase-to-platelet ratio index predicts complications following total shoulder arthroplasty.

Background: This study investigates the association between aspartate aminotransferase-to-platelet ratio index (APRI), a noninvasive measure of liver function, and 30-day postoperative complications following total shoulder arthroplasty (TSA). Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent TSA between 2015 and 2021. The study population was divided into 4 groups based on preoperative APRI: normal/reference (APRI ≤ 0.5), mild fibrosis (0.5 < APRI ≤ 0.7), significant fibrosis (0.7 < APRI ≤ 1), and cirrhosis (APRI > 1). Multivariate logistic regression analysis was conducted to investigate the connection between preoperative APRI and postoperative complications. Results: Compared to the reference group, significant fibrosis was independently associated with a greater likelihood of major complications (odds ratio [OR]: 1.82, 95% confidence interval [CI]: 1.11-2.99; P = .017), minor complications (OR: 2.70, 95% CI: 1.67-4.37; P < .001), pneumonia (OR: 5.78, 95% CI: 2.58-12.95; P < .001), blood transfusions (OR: 2.89, 95% CI: 1.57-5.32; P < .001), readmission (OR: 1.88, 95% CI: 1.10-3.21; P = .022), and non-home discharge (OR: 1.83, 95% CI: 1.23-2.73; P = .003). Cirrhosis was independently associated with a greater likelihood of minor complications (OR: 3.96, 95% CI: 2.67-5.88; P < .001), blood transfusions (OR: 5.85, 95% CI: 3.79-9.03; P < .001), failure to wean off a ventilator (OR: 9.10, 95% CI: 1.98-41.82; P = .005), and non-home discharge (OR: 2.06, 95% CI: 1.43-2.96; P < .001). Conclusion: Increasing preoperative APRI was associated with an increasing rate of postoperative complications following TSA.

Chronic Steroid Use, Complications, and Readmission Following Open Reduction Internal Fixation of Distal Radius Fracture.

Purpose: The increasing incidence of both distal radius fractures (DRFs) and chronic conditions that necessitate long-term steroid use has resulted in a growing intersection between the patient populations of the two. Chronic steroid use is known to increase bone frailty and the likelihood of fractures but may also contribute to poorer outcomes following the repair of DRF. The purpose of this study was to investigate the association between preoperative chronic steroid use, postoperative complications, and readmission after open reduction internal fixation (ORIF) of DRF. Methods: The American College of Surgeons National Surgical Quality Improvement database was queried for all patients who underwent DRF ORIF between 2015 and 2021. However, 30-day postoperative complications after DRF ORIF were collected. Multivariate logistic regression analysis was conducted to investigate the relationship among preoperative chronic steroid use, postoperative complications, and patient factors associated with readmission. Results: The postoperative complications associated with the steroid cohort were categorized as major, minor, and overall complications. Additionally, pneumonia, stroke, myocardial infarction, bleeding transfusions, deep vein thrombosis, pulmonary embolism, readmission, non-home discharge, and mortality were recorded. Chronic steroid use was found to be independently associated with major , minor, and overall complications, deep vein thrombosis, and readmission. Further investigation of readmission showed that male sex and comorbid chronic obstructive pulmonary disease were the only two patient factors independently associated with a greater likelihood of readmission after DRF ORIF. Conclusions: Preoperative chronic steroid use was associated with an increasing rate of postoperative complications after DRF ORIF. Male sex and comorbid chronic obstructive pulmonary disease were characteristics of chronic steroid-use patients independently associated with increased risk of readmission after DRF ORIF. A better understanding of preoperative chronic steroid use as a risk factor for postoperative complications may allow surgeons to improve preoperative risk stratification and patient counseling in the management of DRF. Type of study/level of evidence: Prognostic III.

Cardiac CT angiography (CTA) and nuclear myocardial perfusion imaging (MPI)-a comparison in detecting significant coronary artery disease.

RATIONALE AND OBJECTIVES: Endowed with sufficient diagnostic accuracy, electron beam computed tomography angiography (CTA) is being increasingly used to evaluate coronary arteries. However, data on direct comparisons with nuclear myocardial perfusion studies are limited. In this study, we sought to compare the accuracies of CTA and myocardial perfusion imaging (MPI) for identifying symptomatic patients with hemodynamically significant obstructive coronary artery disease (CAD). MATERIALS AND METHODS: In a single-center study, symptomatic outpatients who were scheduled for cardiac catheterization were prospectively enrolled. Only patients with exertional angina or dyspnea were included. After fulfilling the inclusion criteria, 30 patients were enrolled in the study (mean age 54 +/- 9 years and 70% males). Patients underwent MPI, CTA including coronary artery calcification (CAC) measure, and invasive coronary angiography for evaluation of obstructive coronary artery disease. Significant CAD was defined as >50% left main artery stenosis or >70% stenosis of any other epicardial vessel by invasive angiography. The sensitivities, specificities and predictive values of MPI, CAC, and CTA were analyzed per patient RESULTS: CTA demonstrated significant higher sensitivity than MPI (95% vs. 81%, P < .05). CTA demonstrated significantly higher specificity than both MPI (89% versus 78%, P = .04) and CAC (56%, P = .002). CTA also performed better in a per-vessel analysis (sensitivity 94%, specificity 96%) than both nuclear and CAC. There were no significant differences between the sensitivities and specificities of MPI and CAC. CONCLUSION: CTA accurately detects obstructive CAD in symptomatic patients and may be more accurate than MPI or CAC assessment. Larger studies in a more diverse population are needed.
