RESUMEN
PURPOSE: This study investigates the association between preoperative serum sodium levels 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 2022. The study population was divided into two groups based on preoperative serum sodium levels: eunatremia (135-144 mEq/L) and hyponatremia (< 135 mEq/L). Logistic regression analysis was performed to investigate the relationship between hyponatremia and early postoperative complications. RESULTS: Compared to eunatremia, hyponatremia was independently associated with a significantly greater likelihood of experiencing any complication (odds ratio [OR] 1.65, 95% confidence interval [CI] 1.14-2.40; P = .008), blood transfusions (OR 2.45, 95% CI 1.24-4.83; P = .010), unplanned reoperation (OR 2.27, 95% CI 1.07-4.79; P = .032), and length of stay > 2 days (OR 1.63, 95% CI 1.09-2.45; P = .017). CONCLUSION: Hyponatremia was associated with a greater rate of early postoperative complications following noninfectious revision TSA. This study sheds light on the role of preoperative hyponatremia as a risk factor for postoperative complications and may help surgeons better select surgical candidates and improve surgical outcomes in the setting of revision TSA.
RESUMEN
Purpose: To evaluate the performance of four large language models (LLMs)-GPT-4, PaLM 2, Qwen, and Baichuan 2-in generating responses to inquiries from Chinese patients about dry eye disease (DED). Design: Two-phase study, including a cross-sectional test in the first phase and a real-world clinical assessment in the second phase. Subjects: Eight board-certified ophthalmologists and 46 patients with DED. Methods: The chatbots' responses to Chinese patients' inquiries about DED were assessed by the evaluation. In the first phase, six senior ophthalmologists subjectively rated the chatbots' responses using a 5-point Likert scale across five domains: correctness, completeness, readability, helpfulness, and safety. Objective readability analysis was performed using a Chinese readability analysis platform. In the second phase, 46 representative patients with DED asked the two language models (GPT-4 and Baichuan 2) that performed best in the in the first phase questions and then rated the answers for satisfaction and readability. Two senior ophthalmologists then assessed the responses across the five domains. Main outcome measures: Subjective scores for the five domains and objective readability scores in the first phase. The patient satisfaction, readability scores, and subjective scores for the five-domains in the second phase. Results: In the first phase, GPT-4 exhibited superior performance across the five domains (correctness: 4.47; completeness: 4.39; readability: 4.47; helpfulness: 4.49; safety: 4.47, p < 0.05). However, the readability analysis revealed that GPT-4's responses were highly complex, with an average score of 12.86 (p < 0.05) compared to scores of 10.87, 11.53, and 11.26 for Qwen, Baichuan 2, and PaLM 2, respectively. In the second phase, as shown by the scores for the five domains, both GPT-4 and Baichuan 2 were adept in answering questions posed by patients with DED. However, the completeness of Baichuan 2's responses was relatively poor (4.04 vs. 4.48 for GPT-4, p < 0.05). Nevertheless, Baichuan 2's recommendations more comprehensible than those of GPT-4 (patient readability: 3.91 vs. 4.61, p < 0.05; ophthalmologist readability: 2.67 vs. 4.33). Conclusions: The findings underscore the potential of LLMs, particularly that of GPT-4 and Baichuan 2, in delivering accurate and comprehensive responses to questions from Chinese patients about DED.
RESUMEN
PURPOSE: This study investigates the association between preoperative hypoalbuminemia and 30-day postoperative complications following noninfectious revision total shoulder arthroplasty (TSA). 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 2021. The study population was divided into two groups based on preoperative serum albumin: normal albumin (≥ 3.5 g/dL) and hypoalbuminemia (< 3.5 g/dL). Logistic regression analysis was conducted to investigate the relationship between preoperative hypoalbuminemia and postoperative complications. RESULTS: Compared to normal albumin, hypoalbuminemia was independently associated with a significantly greater likelihood of experiencing any complication (odds ratio [OR] 3.26, 95% confidence interval [CI] 2.04-5.19; P < .001), sepsis (OR 9.92, 95% CI 1.29-76.35; P = .028), blood transfusions (OR 2.89, 95% CI 1.20-6.93; P = .017), non-home discharge (OR 2.88, 95% CI 1.55-5.35; P < .001), readmission (OR 3.46, 95% CI 1.57-7.58; P = .002), and length of stay > 2 days (OR 3.00, 95% CI 1.85-4.86; P < .001). CONCLUSIONS: Preoperative hypoalbuminemia was associated with early postoperative complications following revision TSA. LEVEL OF EVIDENCE: Level III; Retrospective Cohort Comparison; Prognosis Study.
RESUMEN
Background: This study investigates the association between the Geriatric Nutritional Risk Index (GNRI), a measure of malnutrition risk, and 30-day postoperative complications following revision total hip arthroplasty (rTHA). Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients ≥65 who underwent aseptic rTHA between 2015 and 2021. The final study population (n = 7119) was divided into 3 groups based on preoperative GNRI: normal/reference (GNRI >98) (n = 4342), moderate malnutrition (92 ≤ GNRI ≤98) (n = 1367), and severe malnutrition (GNRI <92) (n = 1410). Multivariate logistic regression analysis was conducted to investigate the association between preoperative GNRI and 30-day postoperative complications. Results: After controlling for significant covariates, the risk of experiencing any postoperative complications was significantly higher with both moderate (odds ratio [OR] 2.08, P < .001) and severe malnutrition (OR 8.79, P < .001). Specifically, moderate malnutrition was independently and significantly associated with deep vein thrombosis (OR 1.01, P = .044), blood transfusions (OR 1.78, P < .001), nonhome discharge (OR 1.83, P < .001), readmission (OR 1.27, P = .035), length of stay >2 days (OR 1.98, P < .001), and periprosthetic fracture (OR 1.54, P = .020). Severe malnutrition was independently and significantly associated with sepsis (OR 3.67, P < .001), septic shock (OR 3.75, P = .002), pneumonia (OR 2.73, P < .001), urinary tract infection (OR 2.04, P = .002), deep vein thrombosis (OR 1.01, P = .001), pulmonary embolism (OR 2.47, P = .019), acute renal failure (OR 8.44, P = .011), blood transfusions (OR 2.78, P < .001), surgical site infection (OR 2.59, P < .001), nonhome discharge (OR 3.36, P < .001), readmission (OR 1.69, P < .001), unplanned reoperation (OR 1.97, P < .001), length of stay >2 days (OR 5.41, P < .001), periprosthetic fractures (OR 1.61, P = .015), and mortality (OR 2.63, P < .001). Conclusions: Malnutrition has strong predictive value for short-term postoperative complications and has potential as an adjunctive risk stratification tool for geriatric patients undergoing rTHA.
RESUMEN
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.

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.
RESUMEN
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.

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.

BACKGROUND: Transgender and gender nonconforming (TGNC) individuals experience incongruence between their self-identified gender versus their birth-assigned sex. In some cases, TGNC patients undergo gender-affirming surgical (GAS) procedures. Although GAS is an evolving surgical field, there is currently limited literature documenting patient characteristics and procedures. Addressing this knowledge gap, this retrospective cohort analysis described the characteristics of New York State's TGNC residents with gender dysphoria (GD) diagnosis, including patients undergoing at least one gender-affirming surgical procedure. METHODS: Using the New York Statewide Planning and Research Cooperative System (SPARCS) database from 2002 to 2018, we identified patients' first-time TCNC records and their risk characteristics. Patients who received GAS procedures were sub-classified as top-only, bottom-only, or combined top/bottom procedures and were compared with TGNC patients who did not receive GAS. RESULTS: Of 24,615 records extracted from TGNC SPARCS database, 11,427 (46.4%) were transmasculine (female-to-male) and 13,188 (53.6%) were transfeminine (male-to-female). Overall, 2.73% of transgender patients received at least one GAS procedure. Of these patients, 78.2% had masculinizing and 21.8% had feminizing surgeries. After a diagnosis of GD, the positive predictors for a GAS-based procedure included female birth sex, pediatric age (<18 years) or older age (60+ years), commercial insurance coverage, and Hispanic race. In contrast, negative GAS predictors included male birth sex and government insurance coverage (i.e., Medicare and Medicaid). CONCLUSIONS: Compared with transgender women, transgender men were more likely to receive at least one GAS procedure. Because the race, ethnicity, and payor status of TGNC patients can impact GAS treatment rates, additional research is warranted to examine post-diagnosis GAS treatment disparities among TGNC patients.

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.
RESUMEN
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.

Conclusion: Malnutrition based on GNRI is a strong predictor of complications following TSA, with increasing severity related to an increased rate of complications.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
RESUMEN
BACKGROUND: Among plastic surgeons, there are several conventional techniques for performing chest surgery. Research on surgical approaches has focused cis-gender patients with medical conditions, such as breast cancer or gynecomastia, but has never studied transgender populations. The aim of this study is to perform the first systematic review of gender-affirming surgery (GAS) in transgender populations and determine postoperative outcomes differences in relation to surgical technique. METHODS: Two reviewers independently searched Medline, Embase, CINAHL, Web of Science, and Cochrane databases for studies published prior to 2021. Studies selected for inclusion were retrospective or prospective studies of adult transgender men undergoing GAS that utilized appropriate operative techniques and reported complications and/or patient-reported outcomes. RESULTS: A total of 26 randomized controlled trials, including 40 distinct populations and 3055 patients, were identified. Surgical techniques compared double incision free nipple graft (DIFNG) (2053 patients [67.20%]), pedicled nipple techniques (PNT) (297 [9.72%]), and periareolar techniques (PAT) (705 [23.08%]). Pairwise analysis found the lowest complication rates associated with procedures utilizing DIFNG, followed by PNT, then PAT. Patients with PAT had significantly higher satisfaction scores than DIFNG. CONCLUSIONS: This is the first systematic review to evaluate outcomes of chest surgery techniques among the transgender population. Results indicate significantly more complications for PAT compared to DIFNG or PNT. Analysis of patient-reported outcomes was limited due to heterogeneity in reporting.

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.
RESUMEN
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.
RESUMEN
BACKGROUND: Iron deficiency anemia is a common paraesophageal hernia (PEH) symptom and may improve after repair. When present, anemia has also been proposed to be associated with an increase in length of hospital stay, morbidity, and mortality after PEH repair. This study aimed to determine anemia-related factors in patients with PEH, the rate of anemia resolution after PEH repair, and the risk of anemia recurrence when repair failed. METHODS: We included patients who received a PEH repair between June 2019 and June 2020 and had 24 months of postoperative follow-up. Demographics and comorbidities were recorded. Anemia was defined as pre-operative hemoglobin values < 12.0 for females and < 13.0 for males, or if patients were receiving iron supplementation. Anemia resolution was determined at 6 months post-op. Length of hospital stay, morbidity, and mortality was recorded. Logistic regression and ANCOVA were used for binary and continuous outcomes respectively. RESULTS: Of 394 patients who underwent PEH repair during the study period, 101 (25.6%) had anemia before surgery. Patients with pre-operative anemia had larger hernia sizes (6.55 cm ± 2.77 vs. 4.34 cm ± 2.50; p < 0.001). Of 68 patients with available data by 6 months after surgery, anemia resolved in 36 (52.9%). Hernia recurred in 6 patients (16.7%), 4 of whom also had anemia recurrence (66.7%). Preoperative anemia was associated with a higher length of hospital stay (3.31 days ± 0.54 vs 2.33 days ± 0.19 p = 0.046) and an increased risk of post-operative all-cause mortality (OR 2.7 CI 1.08-6.57 p = 0.05). Fundoplication type (p = 0.166), gastropexy, or mesh was not associated with an increased likelihood of resolution (OR 0.855 CI 0.326-2.243; p = 0.05) (OR 0.440 CI 0.150-1.287; p = 0.05). CONCLUSIONS: Anemia occurs in 1 out of 4 patients with PEH and is more frequent in patients with larger hernias. Anemia is associated with a longer hospital stay and all-cause mortality after surgery. Anemia recurrence coincided with hernia recurrence in roughly two-thirds of patients.
