RESUMO
INTRODUCTION: Little is known about the relationship between body mass index (BMI), a function of mass and height (masskg/height2m) and long-term outcomes among traumatic injury survivors. In this prospective cohort study, we investigate the relationship between BMI and long-term health outcomes in the trauma population. METHODS: Adult trauma survivors with an injury severity score ≥9 admitted to one of three level 1 trauma centers, from January 1, 2015 to December 31, 2022, were surveyed via telephone between 6 and 12 mo postinjury. Participants were stratified into one of five groups by BMI at the time of trauma: L-BMI (BMI <18.5), N-BMI (BMI 18.5-24.9), H1-BMI (BMI 25-29.9), H2-BMI (BMI 30-34.9), and H3-BMI (BMI ≥35); N-BMI was used as the referent. Mental and physical health-related quality of life scores, pain, new functional limitations, and hospital readmissions were evaluated. Univariate and multivariate analyses were used to compare outcomes between study groups. RESULTS: 3830 patients were included. Of those, 124 were L-BMI (3.2%), 1495 N-BMI (39%), 1318 H1-BMI (34.4%), 541 H2-BMI (14.1%), and 352 H3-BMI (9.2%). L-BMI was associated with adverse physical (b = -3.13, CI = -5.71 to -0.55, P = 0.017) and mental health (b = -3.17, CI = -5.87 to -0.46, P = 0.022) outcomes 6-12 mo postinjury compared to the referent. H1-BMI and H2-BMI had higher odds of wo`rse physical outcomes (b = -1.47, CI = -2.42 to -0.52, P = 0.002; b = -3.11, CI = - 4.33 to -1.88, P ≤ 0.001, respectively) and chronic pain (adjusted odds ratio (aOR) = 1.24, CI = 1.04-1.47, P = 0.016; aOR = 1.52, CI = 1.21-1.90, P ≤ 0.001, respectively). Patients with H3-BMI had higher odds of worse physical outcomes compared to N-BMI (b = -4.82, CI = -6.28 to -3.37, P ≤ 0.001), chronic pain (aOR = 2.11, CI = 1.61-2.78, P ≤ 0.001), all-cause hospital readmissions (aOR = 1.62, CI = 1.10-2.34, P = 0.013), and new functional limitations (aOR = 1.39, CI = 1.08-1.79, P = 0.01). CONCLUSIONS: BMI variance above or below N-BMI is associated with worse long-term outcomes following traumatic injury.
RESUMO
PURPOSE: Total hip arthroplasty (THA) is the gold standard in the treatment of advanced hip osteoarthritis. However, hip resurfacing (HR) arthroplasty may present a viable alternative. The aim of this study was to compare complications, implant survivorship, and functional outcomes between HR and THA, to assess HR as a valid and safe alternative to THA. METHODS: Inclusion criteria were randomized clinical trials (RCTs) published in English, comparing clinical outcomes and complications between HR and THA. A systematic review of the literature was performed on PubMed, Scopus and Cochrane Library, following the PRISMA 2020 statement, from January 1, 2015 to November 30, 2023. A meta-analysis was performed by Review Manager (RevMan) software version 5.4 to compare the rates of revisions, dislocations, infection, aseptic loosening and pseudotumor, and the clinical outcomes between the two groups. We used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) to assess the risk of bias. RESULTS: A total of 8 RCT were included, involving 844 patients (387 hips for HR group and 469 hips for THA group). The mean follow-up was 7.72 years. There were no statistically significant differences between the two groups for UCLA and WOMAC score, revision rate, infection, aseptic loosening and pseudotumor (all p > 0.05), while the dislocation rate was significantly lower in the HR group (p = 0.04). CONCLUSIONS: HR is a safe and effective alternative to THA. However, several factors are involved to reduce the complication rate and achieve high implant survival.
RESUMO
OBJECTIVES: Critical shoulder angle (CSA) and acromial index (AI) are two radiographic signs that can influence the risk of rotator cuff tears and the outcomes of repair. The purpose of this study was to determine the influence of CSA and AI on massive cuff tears and on the functional outcomes after repair. The hypothesis was that CSA and AI will be higher in posterosuperior compared to anterosuperior tears. METHODS: CSA and AI were retrospectively measured on radiographs of patients who underwent repair of two rotator cuff tendons. Functional outcomes were evaluated using American Shoulder and Elbow Surgeons (ASES) score and Simple Shoulder Test (SST) at least six months postoperatively. Patients were divided according to the tendons repaired into anterosuperior group and posterosuperior group. Radiographic measurements and functional outcomes were compared. Patients in the posterosuperior group were subdivided into low or high CSA (cut-off value= 39), and into low or high AI (cut-off value = 0.75). All available preoperative magnetic resonance images were reviewed and graded according to Goutallier classification. Multivariate analysis was used to determine the influence of CSA, AI and Goutallier grade on functional outcomes. RESULTS: Eighty six patients were included. Both CSA and AI were statistically significantly higher in the posterosuperior group (p=0.0143 and 0.0052 respectively). After a mean follow up of 33 months, ASES and SST were significantly better in patients with Goutallier grades 0-1 than grades>1 (multivariate p = 0.03 and 0.009 respectively). No statistically significant differences were found between low and high CSA and AI groups in terms of functional outcomes of the posterosuperior group after repair (multivariate p = 0.9). CONCLUSION: Higher critical shoulder angle and acromial index seem to increase the risk of posterosuperior more than anterosuperior rotator cuff tears. Neither of these radiographic parameters influenced the functional outcomes of massive posterosuperior tears after repair. LEVEL OF EVIDENCE: Level III.
RESUMO
PURPOSE: This study aimed to identify the risk factors for anterior knee pain (AKP) after medial patellofemoral ligament reconstruction (MPFLR). METHODS: Patients aged 15-35 years who underwent isolated MPFLR between 2012 and 2022 were included in the study. These patients were divided into two groups (AKP and control group). Patient demographics and preoperative and postoperative clinical outcomes between the two groups were assessed and compared. Univariate logistic regression analysis was performed to explore the potential risk factors associated with postoperative AKP. Subgroup analysis stratified the results based on the time to return to sports (RTS) (>9 and ≤9 months). Furthermore, Spearman correlation analysis was performed to investigate the association between Kujala score and time to RTS. RESULTS: A total of 206 patients were included (AKP, n = 59; control, n = 147). At the 2-year follow-up, patients with AKP demonstrated a shorter duration in returning to their pre-injury activity level compared to those without AKP (9.0 ± 3.6 vs. 10.3 ± 2.7 months, p < 0.05). RTS earlier than 9 months after MPFLR was the only significant risk factor associated with postoperative AKP (odds ratio, 2.13, 95% confidence interval, 1.03-4.39; p < 0.05). Further subgroup analysis revealed that patient RTS earlier than 9 months exhibited worse patient-reported outcomes in both the total cohort and control group (p < 0.05). Furthermore, among patient RTS within 9 months, a longer recovery duration before RTS strongly correlated with a higher Kujala score (R = 0.670, p < 0.001). CONCLUSIONS: Young patients who RTS at their pre-injury levels before 9 months after MPFLR have a higher incidence of postoperative AKP and poorer functional outcomes compared to those who delay their return. Specifically, within the first 9 months after MPFLR, the earlier the RTS, the more severe the AKP symptoms. Careful consideration of the timing for RTS may help reduce the incidence of postoperative AKP. LEVEL OF EVIDENCE: Level III.
RESUMO
INTRODUCTION: Treatment of proximal humerus fractures remains controversial. Understanding the factors that can affect the long-term functional outcomes can aid with management choices. This primary aim of this paper is to evaluate the association of radiographic parameters with functional outcomes. METHODS: Radiographic parameters [Caput-collum-diaphyseal (CCD) angles, Y-scapular angles, and humeral head height (HHH)] were studied. The patients were split into varus and valgus groups based on the CCD angles and retroverted and anteverted groups based on Y-scapular angles. Functional outcome was measured by Oxford Shoulder Score (OSS), Constant Shoulder Score (CSS), and quick Disabilities of Arm, Shoulder and Hand score at 1 year follow-up. Intra- and interrater reliability were measured with the intraclass correlation coefficients (ICCs). Receiver operator curve (ROC) analysis and logistic regression analysis defined the optimal value for abnormalities on radiographic evaluation as an outcome predictor. RESULTS: 111 patients were recruited (mean age 69, 78% female). Median final radiographic assessment was at 7 months. Mean initial/final CCD was 119o /111o (varus, n = 36) and 153o/140o (valgus, n = 75). Mean initial/final Y-scapula angle was 27o/27o (retroversion, n = 101) and 70o/40o (anteversion, n = 9). There was a significant relationship between OSS and final Y-scapular angle in the retroverted group (adj coeff 0.034, p = 0.009) with optimum predictive retroversion angulation of 25o predicting poor functional outcome (OSS < 40), area under the ROC curve of 0.614. Higher initial valgus and retroversion significantly predicted more change in the final angle (adj coeff - 0.349, p = 0.002, adj coeff - 0.527, p < 0.001 respectively). Both intra-rater and inter-rater reliability for the radiographic parameters were excellent (ICC > 0.9). CONCLUSION: Radiographic parameters whilst having excellent reliability, have a limited ability to predict short-term functional recovery. The extent of retroversion is the most important predictor for functional recovery with 25o a cut-off guide. Fractures with a higher initial valgus and retroversion tend to displace more.
RESUMO
AIMS: The objective of this study was to evaluate the effectiveness of batroxobin in improving functional outcomes and reducing stroke recurrence among patients with acute ischemic stroke beyond the therapeutic time window for thrombolytic therapy. METHODS: This multicenter, retrospective study enrolled 492 patients with acute moderate-to-severe ischemic stroke within 24 h. 238 patients were given standard (basic) therapy. On the basis of standard treatment, 254 patients received an initial intravenous infusion of batroxobin 10 U on day 1, followed by subsequent infusions of batroxobin 5 U on the 3rd and 5th days, respectively. RESULTS: In the batroxobin group, 8.3% of patients experienced recurrence stroke, compared to 17.2% in the control group (HR, 0.433; 95% CI, 0.248 to 0.757; p = 0.003). Furthermore, intravenous batroxobin significantly improved the distribution of 90-120 day disability. Moderate-to-severe bleeding events were reported in three patients (1.2%) in the batroxobin group and one patient (0.4%) in the control group (p = 0.369). CONCLUSIONS: Among patients with acute moderate-to-severe ischemic stroke beyond the time window for thrombolytic therapy, treatment with intravenous batroxobin had a lower risk of stroke recurrence and a better recovery of function outcome without increasing bleeding events. Prospective studies are needed to further confirm.

Background Anterior cruciate ligament reconstruction (ACLR) is a crucial procedure in orthopedic surgery. This study evaluates the efficacy and safety of ACLR employing suspensory tibial fixation with a polyether ether ketone (PEEK) button. Methodology This retrospective observational study conducted at Sai Shree Hospital, Pune, India, between November 2023 and December 2023 enrolled 47 subjects aged 18-60 years who underwent arthroscopic ACLR utilizing the T-Button-A Adjustable Loop Ultra-High-Molecular-Weight Polyethylene Suture PEEK button. The functional outcomes and patient-reported outcomes were assessed using the International Knee Documentation Committee (IKDC) score, the Modified Cincinnati Rating System Questionnaire (MCRS), the Single Assessment Numeric Evaluation (SANE) score, the Tegner Activity Level (TAL) Scale, and Knee Injury and Osteoarthritis Outcome Score (KOOS) quality of life subscale. Results Femoral fixation utilized 27 (57.4%) Proloop Ultra Adjustable Loop Button 60 mm, 19 (40.4%) Infiloop Fixed Loop Button 20 mm, and 1 (2.1%) Infiloop Fixed Loop Button 30 mm. Tibial fixation solely relied on T-Button A (PEEK Tibial Button With Adjustable Loop 90 mm). Postoperative evaluations revealed favorable IKDC (79.49 ± 12.67), MCRS (81.32 ± 11.57), SANE (77.83 ± 11.11), TAL Scale (3.87 ± 0.99) and KOOS quality of life subscale (83.81 ± 13.07) scores. Conclusions The findings affirm the efficacy and safety of arthroscopic ACLR utilizing suspensory tibial fixation with the PEEK button, supporting its use for improved patient outcomes.
RESUMO
BACKGROUND: Inï¬ammatory markers for the prognosis of acute ischemic stroke (AIS) with endovascular therapy remain unclear. The purpose of this study was to investigate the association between the Systemic Inflammatory Response Index (SIRI) and Neutrophil-to-Lymphocyte Ratio (NLR) with unfavorable functional outcomes at 90-day in individuals of AIS who underwent endovascular therapy. METHODS: 128 AIS patients who had endovascular therapy were enrolled from the Nanjing Stroke Registry between September 2019 and November 2022. Peripheral venous blood was collected from patients within 24 h of admission for information on the following parameters: neutrophil count, lymphocyte count, monocyte count. Then, the SIRI and NLR values were calculated, and the association among SIRI, NLR, and modiï¬ed Rankin Scale (mRS) scores 90 days after endovascular therapy was examined via univariate and multivariate logistic analyses. ROC curves were utilized to determine the best threshold for SIRI and NLR in predicting negative neurological outcomes following endovascular treatment for patients with AIS. RESULTS: 128 participants were evaluated, among which 50% had unfavorable outcomes. Linear regression analysis showed that the best threshold for SIRI was >1.407 (OR = 1.265; 95% CI, 1.071-1.493; P = 0.006), and for NLR it was >5.347 (odds ratio; OR = 1.088; 95% confidence interval [CI], 1.007-1.175; P = 0.033). These results revealed NLR and SIRI as significant predictors of unfavorable outcomes at 90 days. The AUC for SIRI and NLR in predicting 90-day adverse outcomes was 0.643 and 0.609, respectively. CONCLUSIONS: Higher SIRI and NLR levels at admission may lead to unfavorable outcomes at 90 days for AIS patients with endovascular therapy.
RESUMO
OBJECTIVE: This study aimed to evaluate the association between stress hyperglycemia ratio (SHR) and poor functional outcomes at 90 days in patients with acute ischemic stroke (AIS). METHODS: This study retrospectively collected 1988 AIS patients admitted to two hospitals in the Shenzhen area between January 2022 and March 2023. A total of 1255 patients with Fasting Blood-glucose (FBG) and hemoglobin A1c (HbA1C) values at admission were included in this analysis. SHR, measured by FBG/HbA1C, was evaluated as both a tri-categorical variable (Tertile 1: ≤ 0.83; Tertile 2: 0.84 -0.95; Tertile 3: ≥ 0.96). The outcome was poor functional outcomes (modified Rankin Scale [mRS] score 2-6) at 90 days. We performed univariate analysis, multiple equation regression analysis, stratified analysis, and interactive analysis. RESULTS: Compared with patients in the lowest tertile of SHR, the highest tertile group had significantly lower odds of achieving poor functional outcomes (adjusted odds ratio, OR = 2.84, 95% CI: 2.02-3.99, P < 0.0001) at 90 days after adjusting for potential covariates. Similar results were observed after further adjustment for white blood cell count, neutrophil count, lymphocyte count, fasting blood glucose, stroke type, intravenous thrombolytic therapy, baseline Glasgow score, and baseline NIHSS score. CONCLUSION: SHR, as measured by the FBG/HbA1C, was associated with an increased odds of achieving poor functional outcomes in patients with AIS at 90 days.

INTRODUCTION: This study aims to evaluate the long-term psychosocial and functional outcomes of successful digital replantation following traumatic amputation. METHODS: Patients that underwent successful replantation (i.e. no secondary amputation following replantation) of one or more traumatically amputated digits between January 2009 and April 2019 were invited to participate in this study. In addition to a custom questionnaire on psychosocial and socioeconomic aspects of life, various Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaires regarding global health, upper extremity function, and depressive symptoms were completed. Bivariate analyses were performed to identify significant associations between outcomes and explanatory variables. RESULTS: Thirty-six patients were successfully enrolled and completed the questionnaires at a median follow-up of 6.1 years. The median PROMIS score for Upper Extremity Function (40.6) was considerably different from the score that is typically found in the general population (all PROMIS instruments are calibrated with a control group score of 50.0), but the median PROMIS scores for Global Health - Physical (49.0), Global Health - Mental (50.7), and Depression (45.6) were comparable to those among the general population. Dominant hand injury, a greater number of injured digits, higher age at the time of injury, and the need for neuropathic pain medication were associated with lower Upper Extremity Function scores (all p < 0.05). Additionally, the presence of neuroma was associated with negative changes in both household finances and mental well-being (p < 0.05). CONCLUSIONS: At long-term follow-up, a majority of patients that underwent replantation of traumatically amputated digits seem to cope well based on psychosocial and functional outcomes. However, neuropathic pain and the presence of neuroma are strong negative factors. Specific attention to digital nerves at the time of surgery is crucial in the management of traumatic amputations.
RESUMO
Background: Multiligament reconstruction (MLR) has become the standard surgical approach for treating multiligament knee injuries (MLKIs). Purpose: To identify prognostic factors for patient-reported outcome measures, return to work (RTW), return to sports, and radiographic osteoarthritis (OA) (Kellgren-Lawrence grade ≥2) after MLR for MLKI. Study Design: Case-control study; Level of evidence 3. Methods: Included were 52 consecutive patients (age, 35.5 ± 11 years; 75% men), with MLKI sustained between 2013 and 2019 and treated with MLR. At a mean follow-up of 3.8 ± 1.6 years, patient-reported outcome measure scores-including the International Knee Documentation Committee (IKDC), the Knee injury and Osteoarthritis Outcome Score (KOOS), the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI), and the 12-Item Short-Form Health Survey-RTW, return to sports, and weightbearing radiographs were obtained. A total of 20 determinants were hypothesized and tested by univariate logistic regression for binary variables or linear regression for continuous variables. Only factors identified as significant (P < .10) were entered into a multivariate logistic regression model. Results: The prevalence of injury severity according to the Schenck knee dislocation (KD) classification was as follows: KD I (44%), KD III (36%), KD IV (10%), and KD V (10%). Increased KD grades resulted in decreased IKDC (P = .002) and all 5 KOOS subscales (P≤ .007 for all) scores. Medial meniscectomy (23%) was associated with a worse ACL-RSI score (P = .007) and RTW failure (odds ratio [OR], 36.8; P = .035). Peroneal nerve palsy (6%) was associated with a worse ACL-RSI score (P≤ .001). Radiographic OA was observed in 38%, with distribution predominantly patellofemoral (80%) and medial tibiofemoral (45%). Traumatic cartilage damage (Outerbridge grade >2 [37%]) was associated with secondary patellofemoral (OR, 10; P = .012) and medial tibiofemoral (OR, 10; P = .019) OA. Anterior cruciate ligament reconstruction failure (7%) was a risk factor for medial tibiofemoral OA (OR, 25.8; P = .006). Conclusion: Increased Schenck KD grade, permanent peroneal nerve palsy, and irreparable medial meniscus lesions were prognostic factors for worse functional outcomes 3.8 years after MLKI was treated with MLR. Traumatic cartilage damage and anterior cruciate ligament failure were associated with the development of early OA.
RESUMO
Several trends toward patient-centered multi-care models employing translational research strategies are currently emerging in orthopaedics. These align seamlessly with epigenetics discussions in pain, a clinical approach to pain management that prioritizes tailoring healthcare to individual needs, preferences, and circumstances. Recognizing the unique genetic and epigenetic factors influencing pain perception, healthcare providers can integrate personalized insights into their patient-centered approach, offering more targeted and effective pain management strategies tailored to each individual's experience. Custom 3D-printing technologies may also become increasingly relevant to more effectively and reliably treat painful degenerative structural abnormalities. They are expected to go hand-in-hand with the precision medicine redefinition of musculoskeletal care. More effective analysis of surgeons' clinical decision-making and patients' perception of high-value orthopaedic care is needed. Shared Decision Making (SDM) is critical to identifying the best solution for each patient and improving stakeholders' understanding of factors influencing the diverse prioritizing values of surgical or non-surgical treatments by payers, systems, and other providers. Identifying high-value orthopaedic surgeries via effective SDM in orthopedic surgery requires more than just presenting patients with information. The Rasch analysis of patient expectations can provide this nuanced approach that involves understanding patient values, addressing misconceptions, and aligning surgical recommendations with patient-specific goals. Optimizing orthopaedic treatment within the patient-centered framework can drive innovation in reimbursement policies that support the field more broadly. Research on separating high-value from low-value orthopaedic procedures may likely impact healthcare decision- makers' resource allocation.
RESUMO
PURPOSE: Concerns exist regarding the potential for transanal total mesorectal excision (TaTME) to yield poorer functional outcomes compared to laparoscopic TME (LaTME). The aim of this study is to assess the functional outcomes following taTME and LaTME, focusing on bowel, anorectal, and urogenital disorders and their impact on the patient's QoL. METHODS: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and A Measurement Tool to Assess systematic Reviews (AMSTAR) guidelines. A comprehensive search was conducted in Medline, Embase, Scopus, and Cochrane Library databases. The variables considered are: Low Anterior Resection Syndrome (LARS), International Prostate Symptom Score (IPSS) and Jorge-Wexner scales; European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C29 and QLQ-C30 scales. RESULTS: Eleven studies involving 1020 patients (497-taTME group/ 523-LaTME group) were included. There was no significant difference between the treatments in terms of anorectal function: LARS (MD: 2.81, 95% CI: - 2.45-8.08, p = 0.3; I2 = 97%); Jorge-Wexner scale (MD: -1.3, 95% CI: -3.22-0.62, p = 0.19). EORTC QLQ C30/29 scores were similar between the groups. No significant differences were reported in terms of urogenital function: IPSS (MD: 0.0, 95% CI: - 1.49-1.49, p = 0.99; I2 = 72%). CONCLUSIONS: This review supports previous findings indicating that functional outcomes and QoL are similar for rectal cancer patients who underwent taTME or LaTME. Further research is needed to confirm these findings and understand the long-term impact of the functional sequelae of these surgical approaches.

PURPOSE: Phrenic nerve stimulation (PNS) was approved by the Food and Drug Administration (FDA) to treat moderate to severe central sleep apnea. We report here, results of a retrospective study regarding our institutional outcomes at one year. In this study we evaluated the change in the apnea hypopnea index, epworth sleepiness score, and functional outcomes of sleep score at one year post implant. METHODS: This is a retrospective analysis of patients ≥ 18 years of age who had PNS implanted for moderate to severe CSA at the Ohio State University Wexner Medical Center apnea between Feb 1, 2018 to July 1, 2021. Sleep disordered breathing parameters and objective sleepiness as measured by the Epworth Sleepiness Scale (ESS) scores, and Functional Outcomes of Sleep Questionnaire (FOSQ) scores were assessed at baseline and one-year post-implant. RESULTS: Twenty-two patients were implanted with PNS at OSU between February 1, 2018 and May, 31, 2022. The AHI showed a statistically significant decrease from a median of 40 events/hour at baseline to 18 at follow-up (p-value = 0.003). The CAI decreased from 16 events/hour to 2 events/hour (p-value of 0.001). The obstructive apnea index, mixed apnea index, and hypopnea index did not significantly change. The ESS scores had a statistically significant improvement from a median score of 12 to 9 (p-value = 0.028). While the FOSQ showed a trend to improvement from 15.0 to 17.8, it was not statistically significant (p-value of 0.086). CONCLUSION: Our study found that PNS therapy for moderate to severe CSA improves overall AHI and CAI. Objective sleepiness as measured by the ESS also improved at one-year post implant.
RESUMO
Background: The proximal humerus is a common site for primary malignant and benign aggressive bone tumors, necessitating wide resection and subsequent skeletal defect reconstruction. Various reconstruction options include osteoarticular allografts, autografts, endoprosthesis, nail-cement spacer, reverse shoulder arthroplasty, and allograft-prosthesis composites. However, there is no consensus on the optimal reconstruction method. This study aims to compare functional outcomes and complications between these two methods. Methods: A total of 40 patients with proximal humerus tumors who underwent endoprosthesis or nail-cement spacer reconstruction between March 2012 and December 2020 were included. The mean follow-up in the study was 31.37 +/- 12 months. Demographic and clinical data were collected, and functional outcomes were assessed using the Musculoskeletal Tumor Society 93 scoring system and the Disabilities of the Arm, Shoulder, and Hand questionnaire. Complications and oncological outcomes were recorded. Results: Both groups were similar in terms of demographic and clinical variables. Endoprosthesis reconstruction demonstrated significantly better active shoulder forward flexion compared to nail-cement spacer (45.8 vs. 25.2 degrees) (P = .015). Endoprosthesis group also exhibited greater active shoulder internal rotation (68.25 vs. 63.25 degrees) (P = .004). No statistically significant differences were observed in overall functional outcomes. Complications, including radial nerve palsy and infection, were comparable between groups, with one case of spacer loosening. Conclusion: Both endoprosthesis and nail-cement spacer reconstruction provide comparable functional outcomes and complication rates following proximal humerus tumor resection. Nail-cement spacer offers a cost-effective alternative for patients in resource-constrained settings.
RESUMO
Background: The density of contrast medium in digital subtraction angiography (DSA) have been used to evaluate the cerebral circulation function. Our aim was to study the effect of difference in arteriovenous peak optical density (POD) after thrombectomy on functional outcomes. Methods: Consecutive patients with acute ischemic stroke due to large vessel occlusion who underwent thrombectomy were reviewed. We processed DSA images with ImageJ software to measure the POD of internal carotid artery (ICA) and cortical veins. The average POD of cortical veins (PODVA) and the POD difference between ICA and cortical veins (PODICA-CV) were calculated. Primary outcome was good functional outcome (modified Rankin scale score of 0-2 at 90 days). Results: One hundred sixty-six patients were finally included in the study. Patients with good functional outcome had lower ipsilateral PODVA (median [interquartile range (IQR)], 257.198 [216.623-296.631] vs. 290.944 [248.647-338.819], p < 0.001) and lower ipsilateral PODICA-CV (median [IQR], 128.463 [110.233-153.624] vs. 182.01 [146.621-211.331], p < 0.001). Multivariable logistic regression analyses showed that ipsilateral PODVA (odds ratio [OR] 0.991, 95% confidence interval [CI] 0.984-0.999, p = 0.019) and ipsilateral PODICA-CV (OR 0.975, 95% CI 0.963-0.986, p < 0.001) were associated with good functional outcome. The predictive ability was significantly enhanced in the model including ipsilateral PODICA-CV (0.893 vs. 0.842, p = 0.027). No correlation was found between ipsilateral PODICA-CV and expanded Thrombolysis in Cerebral Infarction grades (r = -0.133, p = 0.099). Conclusion: Ipsilateral PODICA-CV is an additional indicator of cerebral reperfusion status and predicts functional outcomes after thrombectomy.
RESUMO
OBJECTIVE: To evaluate complication rate and functional outcomes of nerve-sparing parametrectomy for deep endometriosis in relation to the extension of the surgical procedure, based on recognizable anatomical landmarks. METHODS: This was a prospective single-center study including all patients undergoing parametrectomy for deep endometriosis from September 2020 to June 2023 at our tertiary center. Dorsolateral parametrectomies were divided into parametrectomies medial to the presacral fascia and cranial to the medial rectal artery (superficial parametrectomy), and parametrectomies in which one of the two landmarks was overcome during the surgical procedure, leading to the excision of tissue lateral to the presacral fascia (deep parametrectomy type 1, or DP1) or caudal to the medial rectal artery (DP2). Finally, we used the hypogastric fascia as landmark to define type 3 deep parametrectomy (DP3), when the procedure was deeply lateral to the fascia. RESULTS: Bladder voiding deficit occurred in 9.7% of cases, with higher rates in DP2 (20.8%) and DP3 (30%) groups. Regarding postoperative gastrointestinal function, our data showed a significant improvement over time in all groups, with the exception of DP2; instead an improvement in postoperative bladder function was only shown in DP3. Parametrectomy was not associated with a simultaneous improvement in sexual function expressed with the female sexual function index, in any of the four groups. CONCLUSION: Our classification constitutes a concrete approach for comparing, in a standardized way, the complications and functional outcomes of parametrectomy, which, even if carried out by expert surgeons, demonstrates a non-negligible rate of bladder voiding deficit.
RESUMO
AIM: Diverting stomas are routinely used in restorative surgery following total mesorectal exicision (TME) for rectal cancer to mitigate the clinical risks of anastomotic leakage (AL). However, routine diverting stomas are associated with their own complication profile and may not be required in all patients. A tailored approach based on personalized risk of AL and selective use of diverting stoma may be more appropriate. The aim of the TAilored SToma policY (TASTY) project was to design and pilot a standardized, tailored approach to diverting stoma in low rectal cancer. METHOD: A mixed-methods approach was employed. Phase I externally validated the anastomotic failure observed risk score (AFORS). We compared the observed rate of AL in our cohort to the theoretical, predicted risk of the AFORS score. To identify the subset of patients who would benefit from early closure of the diverting stoma using C-reactive protein (CRP) we calculated the Youden index. Phase II designed the TASTY approach based on the results of Phase I. This was evaluated within a second prospective cohort study in patients undergoing TME for rectal cancer between April 2018 and April 2020. RESULTS: A total of 80 patients undergoing TME surgery for rectal cancer between 2016 and 2018 participated in the external validation of the AFORS score. The overall observed AL rate in this cohort of patients was 17.5% (n = 14). There was a positive correlation between the predicted and observed rates of AL using the AFORS score. Using ROC curves, we calculated a CRP cutoff value of 115 mg/L on postoperative day 2 for AL with a sensitivity of 86% and a negative predictive value of 96%. The TASTY approach was designed to allocate patients with a low risk AFORS score to primary anastomosis with no diverting stoma and high risk AFORS score patients to a diverting stoma, with early closure at 8-14 days, if CRP values and postoperative CT were satisfactory. The TASTY approach was piloted in 122 patients, 48 (39%) were identified as low risk (AFORS score 0-1) and 74 (61%) were considered as high risk (AFORS score 2-6). The AL rate was 10% in the low-risk cohort of patient compared to 23% in the high-risk cohort of patients, p = 0.078 The grade of Clavien-Dindo morbidity was equivalent. The incidence of major LARS was lowest in the no stoma cohort at 3 months (p = 0.014). CONCLUSION: This study demonstrates the feasibility and safety of employing a selective approach to diverting stoma in patients with a low anastomosis following TME surgery for rectal cancer.
