Comparison of clinical, technical, and safety outcomes between the Sofia 5Fr catheter vs. the Sofia 6Fr catheter; a MaSQ-Registry study

BackgroundDirect aspiration during endovascular treatment (EVT) for acute ischemic stroke (AIS) patients is safe and effective. The ‘Soft torqueable catheter Optimized For Intracranial Access’ (Sofia) catheter is commonly used. Data on differences between 5Fr and 6Fr Sofia is limited. Hence, we aimed to compare the clinical, technical, and safety outcomes between both Sofia catheters in AIS patients. MethodsPatients with an intracranial anterior circulation occlusion from the ‘Maastricht Stroke Quality-registry’ (MaSQ-registry), who underwent EVT for AIS from September 2020 to February 2023, and treated with the Sofia catheter in the first-line technique were included. Outcomes included a shift on the modified Rankin Scale (mRS) score at 90 days, favorable functional outcome (mRS 0-2), first-attempt recanalization rate, and per procedural complications. Multivariable regression analyses were performed with adjustments. ResultsOut of 511 registered patients in the MaSQ-registry, 366 patients were included. 281 patients (77 %) were treated with the Sofia 6Fr. No shift towards better outcomes on the ordinal mRS score at 90 days was observed in the Sofia 6Fr group compared to the 5Fr (adjusted common[ac] OR:1.34, 95 %CI:0.70–2.56). Favorable functional outcome (aOR:1.24, 95 %CI:0.49–3.13), and per procedural complications (aOR:1.04, 95 %CI:0.41–2.64) did not differ significantly between Sofia 6Fr and 5Fr. The Sofia 6Fr achieved higher first-attempt successful recanalization rates (53 % versus 34 %; aOR:2.28, 95 %CI:1.11–4.69), and lower total thrombectomy attempts (median:1 versus 2; aβ:–0.63, 95 %CI:–1.21 to –0.05). ConclusionsThe use of 6Fr Sofia aspiration catheter leads in this single-center registry to higher first-attempt successful recanalization rates and fewer thrombectomy attempts compared to the 5Fr Sofia catheter. However, this did not reflect in better clinical outcomes.

Comparative Epidemiological and Clinical Outcomes on COVID-19 and Seasonal Influenza Hospitalized Patients during 2023.

COVID-19 and influenza are highly contagious respiratory viral diseases and priority global public health concerns. We conducted a retrospective observational study of COVID-19 and/or influenza hospitalized cases, during 2023. We identified 170 influenza cases, 150 COVID-19 cases and 3 co-infections. Overall, 29.10% of patients had at least one COVID-19 vaccine dose and 4.6% received the seasonal Flu vaccine. The demographic data found older patients in the COVID-19 group and a higher index of the comorbidities, mainly due to chronic heart diseases, hypertension, and diabetes. Fever, chills, and rhinorrhea were more frequently related to influenza, while cough was prevalent in COVID-19. Antibiotics were more used in influenza than COVID-19, either pre-hospital or in-hospital. The mortality rate within the first 30 days from the onset of the respiratory infection was higher in influenza compared to COVID-19. We concluded that the COVID-19 clinical picture in hospitalized patients is changing to influenza-like symptoms. The evolution is variable, related to chronic comorbidities, but influenza had more frequent severe forms. All through 2023, due to poor vaccination rates, COVID-19 and influenza have continued to cause numerous hospitalizations, and a new strategy for efficient vaccinations is required.

Comparison of Clinical Outcomes in the Slow-Developing Blastocysts With or Without Preimplantation Genetic Testing-Aneuploidy on Day 6 in the Frozen–Thawed Cycle

ObjectivesThis study investigated the potential of the slow-developing blastocysts using preimplantation genetic testing-aneuploidy (PGT-A) in patients undergoing frozen–thawed embryo transfer, stratified by age. MethodsA retrospective analysis was performed including a total of 743 cycles, the first frozen embryo transfer (FET) cycle with single embryo transfer, who underwent treatment between January 2020 and July 2023 in a single fertility centre, Gangnam CHA Fertility Center. A total of 743 cycles, in which we performed intracellular sperm injection and freeze-all strategy, from 743 patients were included. The patient group was divided into 4 groups as follows: group 1 (G1), 208 FET on day 5; group 2 (G2), 177 FET with PGT-A on day 5; group 3 (G3), 220 FET on day 6; group 4 (G4), 138 FET with PGT-A on day 6. We also divided into 2 groups—under 35 years of age and over 35 years of age—and performed the analysis separately for each group. ResultsIn the under 35 years of age group, there were no significant differences in clinical pregnancy and miscarriage rates in G1 and G2 (67.2% vs. 63.8%, not statistically significantly different). Also, G4 had a higher clinical pregnancy rate than G3, but it was not significant (51.8% vs. 54.7%, not statistically significantly different). In the 35 years or older group, G2 had higher pregnancy rates than G1 and lower miscarriage rates (clinical pregnancy rate: 43.3% vs. 67.7%, P = 0.001, miscarriage rate: 22.5% vs. 3.4%, P = 0.001). In addition, G4 had a higher pregnancy rate than G3 and a lower miscarriage rate (clinical pregnancy rate: 31.8% vs. 46.9%, P = 0.003, miscarriage rate: 22.9% vs. 2.2%, P = 0.023). ConclusionsIn the under-35-year-old group, PGT-A on day 5 and day 6 showed a high pregnancy rate and a low miscarriage rate. Therefore, using PGT-A seems advantageous for patients of an advanced maternal age.

Comparison of clinical and patient-reported outcomes in patients with benign euthyroid solitary nodules after ultrasound-guided percutaneous microwave ablation and endoscopic thyroidectomy.

Percutaneous ultrasound-guided microwave ablation (MWA) for benign solid thyroid nodules is the newest modality for treatment. However, the differences in treatment outcomes between MWA and endoscopic thyroidectomy vestibular approach (TOETVA) for patients with benign euthyroid solitary nodules remain unknown. We are sharing initial results from our prospective study. Prospective study between January 2022 and December 2023 was conducted and data were noted at 3 time points in patients planned for treatment (Preoperative, 1week, and 12months). Main outcome measures were clinical outcome and comparison of thyroid-related quality of life using the ThyPRO-39hin and swallowing-related quality of life using the SWAL-QoL. Of the 36 included patients, 20 patients underwent TOETVA and 16 underwent MWA. Both the groups were comparable in terms of demographic and clinicopathological profiles. The nodule volume reduction rate of patients at 12months after MWA was 75.10% and 100% for TOETVA. The mean preoperative ThyPRO-39hin and SWAL-QoL scores were comparable in all domains between the two groups. Mean ThyPRO-39hin and SWAL-QoL scores on postoperative day 7 were significantly better in the MWA group in domains impaired social life (p<0.0001) and impaired daily life (p=0.0002). However, at the end of 12months, mean ThyPRO-39hin and SWAL-QoL scores became significantly better in the TOETVA group as compared to the MWA group. Our findings suggest that transoral endoscopic thyroidectomy results in significant superior clinical outcome, thyroid-related quality of life, and swallowing-related quality of life in the long term.

Randomized Controlled Trial of a Novel Cementless vs. Cemented Total Knee Arthroplasty: Early Clinical and Radiographic Outcomes.

Previous cementless total knee arthroplasty (TKA) designs faced challenges with insufficient initial fixation on tibial side, resulting in inferior functional outcomes and survival rates. The Zoned Trabecular Bone Cementless Knee is a novel implant designed for cementless TKA which aims to achieve excellent initial fixation, promoting effective osseointegration. The aim of this research was to compare the early clinical and radiographic results of this cementless TKA with cemented TKA. Between September 2021 and April 2022, 64 patients (64 knees) were recruited in this prospective randomized controlled trial to receive either cementless 3D-printed trabecular metal TKA or a cemented posterior stabilized TKA. Preoperative and postoperative clinical evaluations, including the range of motion (ROM), Knee Society Score (KSS), and the Reduced Western Ontario and MacMaster Universities Score (WOMAC), were conducted and analyzed for comparison. Radiographs and computed tomography scans were utilized to assess the initial fixation. The complications between the two groups were also recorded and compared. Continuous data were analyzed for significance using independent-samples t-test or the Mann-Whitney U test and categorical data were analyzed using chi-squared or Fisher's exact test. Both groups demonstrated significant enhancement at 12 months follow-up in the ROM compared with baseline (ROM: 94.7 ± 23.4 vs. 113.1 ± 12.3 in cementless group and 96.5 ± 14.7 vs. 111.0 ± 12.8 in cemented group, p < 0.05). However, no statistical differences were observed between the two groups in postoperative ROM, KSS, or WOMAC score. The radiographs and computed tomography scans showed similar results, including radiolucent lines and osteolysis in either femoral or tibial. Additionally, there was no statistical difference in the overall complication rate between the two groups. Notably, one patient in the cementless TKA group required revision for periprosthetic infection as the end point. This novel 3D-printed trabecular metal cementless TKA achieved comparable clinical outcomes and initial fixation to cemented TKA in early stage. Longer-term examination is necessary to validate these results.

Comparisons of clinical outcomes between hypertensive and normotensive living kidney donors: a prospective, multicenter nationwide cohort study.

Living kidney donors with hypertension are potential candidates for solving the donor shortages in renal transplantation. However, the safety of donors with hypertension after nephrectomy has not been sufficiently confirmed. A total of 642 hypertensive and 4,848 normotensive living kidney donors who were enrolled in the Korean Organ Transplantation Registry between May 2014 and December 2020 were included in this study. The study endpoints were a decreased estimated glomerular filtration rate (eGFR) and proteinuria. In the entire cohort, donors with hypertension had a lower eGFR before nephrectomy in comparison to normotensive donors which remained lower after kidney transplantation. The incidence of proteinuria in hypertensive donors increased during follow-up. In propensity score-matched analysis, the risk of eGFR being <60 mL/min/1.73 m2 (hazard ratio [HR], 0.77; 95% confidence interval [CI], 0.50-1.19) or <45 mL/min/1.73 m2 (HR, 0.50; 95% CI, 0.06-4.03) was not significantly increased in donors with hypertension. However, hypertensive donors were found to have a significantly higher risk of proteinuria than normotensive donors (HR, 2.28; 95% CI, 1.05-4.94). Similar findings were also observed in the analysis of the entire cohort, indicating that hypertensive donors had a significantly higher risk of proteinuria (adjusted HR, 1.77; 95% CI, 1.10-2.85), without a substantial increase in the risk of decreased renal function. The risk of proteinuria after donation was substantially increased in donors with hypertension. These findings underscore the need for careful monitoring of proteinuria in hypertensive donors following donation.

Are positional screws superior to lag screws in fixation of medial malleolar fractures? A randomized controlled trial.

There is no consensus about the best fixation method for medial malleolar fractures. This study was conducted to compare the clinical and radiological results of positional (fully threaded) screws and lag (partially threaded) screws when used to fix medial malleolar fractures. This prospective, randomized clinical trial included 68 patients with closed isolated medial malleolar fractures. Each study arm included 34 patients who were randomly treated with either fully threaded screws (FT group) or partially threaded screws (PT group). Patients were evaluated radiologically for union and clinically using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle hindfoot score. After a 12-month follow-up, the mean AOFAS ankle hindfoot score was 92.1 ± 3.5 in the FT group and 91.8 ± 5.4 in the PT group. Union was achieved in the FT group after a mean of 6.2 ± 1.3 weeks and after a mean of 6.5 ± 1.5 weeks in the PT group. Both fully threaded and partially threaded screws yielded good comparable clinical and radiological outcomes when used to fix isolated medial malleolar fractures.

Efficacy and safety of immune checkpoint inhibitors for individuals with advanced EGFR-mutated non-small-cell lung cancer who progressed on EGFR tyrosine-kinase inhibitors: a systematic review, meta-analysis, and network meta-analysis

The clinical benefits of immune checkpoint inhibitor (ICI)-based treatments in treating individuals with advanced EGFR-mutated non-small-cell lung cancer (NSCLC) who have progressed on EGFR tyrosine-kinase inhibitors (TKIs) remain controversial. We aimed to review the literature to comprehensively investigate the individual and comparative clinical outcomes of various ICI-based treatment strategies in this population. In this systematic review and meta-analysis, we used single-arm, pairwise, and network meta-analytical approaches. We searched PubMed, Embase, Cochrane Library, Web of Science, ClinicalTrials.gov, and relevant international conference proceedings from database inception to Jan 31, 2024, without language restrictions, to identify eligible clinical trials that assessed ICI-based treatments for individuals with advanced EGFR-mutated NSCLC who progressed on EGFR-TKIs. Studies considered eligible were published and unpublished phase 1, 2, or 3 clinical trials enrolling participants with histologically or cytologically confirmed advanced EGFR-mutated NSCLC who had progressed after at least one EGFR-TKI treatment, and that evaluated ICI-based treatment strategies on at least one of the clinical outcomes of interest. The primary outcome analysed was progression-free survival. The protocol is registered with PROSPERO, CRD42021292626. 17 single-arm trials and 15 randomised controlled trials, involving 2886 participants and seven ICI-based treatment strategies (ICI monotherapy, ICI plus chemotherapy [ICI-chemo], ICI plus antiangiogenesis [ICI-antiangio], ICI plus antiangiogenesis plus chemotherapy [ICI-antiangio-chemo], dual ICIs [ICI-ICI], dual ICIs plus chemotherapy [ICI-ICI-chemo], and ICI plus EGFR-TKI [ICI-TKI]), were included. Three of these strategies-ICI monotherapy, ICI-antiangio-chemo, and ICI-chemo-had sufficient data across the included studies to perform a pairwise meta-analysis. The pairwise meta-analysis showed that, compared with chemotherapy, ICI monotherapy led to shorter progression-free survival (hazard ratio [HR] 1·73 [95% CI 1·30-2·29], I2=0%), whereas ICI-antiangio-chemo (HR 0·54 [0·44-0·67], I2=0%) and ICI-chemo (HR 0·77 [0·67-0·88], I2=0%) prolonged progression-free survival. The network meta-analysis showed that ICI-antiangio-chemo yielded the best progression-free survival results, with substantial benefits over ICI-chemo (HR 0·71 [95% credible interval 0·59-0·85]), ICI monotherapy (HR 0·30 [0·22-0·41]), and non-ICI treatment strategies including antiangio-chemo (HR 0·76 [0·58-1·00]) and chemotherapy alone (HR 0·54 [0·45-0·64]). ICI-antiangio-chemo was associated with higher risks of both any-grade and grade 3 or worse adverse events over ICI-chemo and chemotherapy in the network meta-analysis. For individuals with advanced EGFR-mutated NSCLC who progressed on EGFR-TKIs, ICI-antiangio-chemo was identified as the optimal treatment option. The toxicity of this treatment was acceptable but needs careful attention. ICI-chemo showed appreciably greater efficacy than the standard-of-care chemotherapy. These findings clarified the roles of ICI-based treatment strategies in this difficult-to-treat refractory population, potentially complementing recent guidelines. None.

Comparison of clinical outcomes and complications of biportal and uniportal endoscopic decompression for the treatment of cervical spondylotic radiculopathy: A systematic review and meta-analysis.

This study aimed to compare the clinical efficacy and complication rates of decompression with unilateral biportal endoscopy (UBE) and percutaneous endoscopy (PE) in cervical spondylotic radiculopathy (CSR). A comprehensive literature review was conducted up to April 2024 across multiple databases, including EMBASE, PubMed, Cochrane Library, China National Knowledge Infrastructure, and Wanfang Data, focusing on clinical studies that compare UBE with PE for posterior foraminotomy and discectomy decompression in CSR. The meta-analysis was performed with an emphasis on evaluating clinical outcomes such as operation time, blood loss, incision length, Neck Disability Index (NDI), Visual Analog Scale (VAS) for neck pain and arm pain, and complications. Out of an initial 1,041 studies identified from electronic databases, eight were deemed eligible based on title, abstract, and full-text screening. These studies involved 552 patients (269 males, 283 females; mean age: 53.9±11.4 years; range, 30 to 79 years), with 287 in the UBE group and 265 in the PE group. Meta-analysis indicated no significant difference in operation time between UBE and PE (mean difference [MD]=-3.68; 95% confidence interval [CI]:-19.38, 12.02; p=0.65). However, both blood loss (MD=17.01; 95% CI: 2.61, 31.41; p=0.02) and incision length (MD=11.62; 95% CI: 9.23, 14.01; p<0.00001) were significantly lower in the PE group compared to the UBE group. Regarding clinical outcomes, no significant differences were observed between the two groups in terms of NDI (MD=0.12; 95% CI:-0.10, 0.34; 0.28), VAS for neck pain (MD=-0.06; 95% CI:-0.19, 0.06; p=0.32), VAS for arm pain (MD=-0.14; 95% CI:-0.26, -0.01; p=0.84), or complications (OR=1.07; 95% CI: 0.54, 2.10; p=0.85). Our findings suggest that there are no significant disparities in clinical outcomes between UBE and PE, encompassing NDI, VAS for arm pain, and VAS for neck pain, as well as complication rates. Notably, compared to PE, UBE results in increased bleeding and longer incision lengths when treating CSR, without substantially reducing operation time.

Outcome of primary fixation of traumatic acetabular fractures

Objectives; Traumatic acetabular fracture is a major injury with high association of mortality, morbidity and long recovery period. Surgical management of acetabular fracture is a technical challenge needing high level of skills and vigilance because of the complex anatomy and risk to surrounding structures. We aim to look at two surgical techniques for fixation of acetabular fracture and their outcome in this study. Methods; Between April 2018 and March 2023, a total of 26 patients (15 males and 11 females) were treated for acetabular fracture fixation. 10 were treated with minima invasive technique Close reduction and per-cutaneous fixation because of good reduction was achieved under image guidance and 16 patients had ORIF with use of various recon plates, screws and wires. Results; All patients were followed up for 12 months. Among all patients, the clinical outcomes were recorded as excellent in 17 patients (17/26, 65%), good in 5 (5/26, 19%), fair in 2 (2/26, 7.7%), and poor in 2 (2/26. 7.7%), according to the modified Merle d’Aubigné-Postel score. The average modified Merle d’Aubigné-Postel score was 15 ± 2.0 points (range, 10–18 points). The radio-logical healing was assessed according to the Matta score [22] and were reported excellent in 15 patients (15/26, 57.6%), good in 7 (7/26, 26.8%), fair in 1 (1/26, 3.8%),and poor in 3 (3/26, 11.5%). Conclusion; our study shows comparable clinical outcome for acetabular fracture fixation using either ORIF or CRPF technique. Right patient choice and good knowledge of anatomy is of paramount importance.

Patient satisfaction after Nuss procedure with one or two bars in young adults: A propensity score-matched cohort study.

The Nuss procedure is the primary treatment for pectus excavatum (PE), but patient expectations are not always met. In our unit, our standard approach in the last few years has been the routine application of two bars instead of one. We aimed to retrospectively assess the impact of this approach on patient satisfaction, quality of life (QoL) and safety. A retrospective study included 182 patients over 16 years old who underwent the Nuss procedure for PE between January 2007 and September 2021. Patients were categorized into one-bar or two-bar correction groups. Propensity score matching (PSM) was used, resulting in 30 patients in each group. Primary endpoints were QoL and cosmetic satisfaction, while secondary endpoints included complications and recurrence. After PSM, both groups showed similar general characteristics. Patients treated with two bars reported fewer psychological complaints post-surgery (93.3% vs. 73.3%, p = 0.031). There were no significant differences in QoL improvement (96.7% in both groups, p = 0.197), perioperative complications (p = 0.771) or recurrence (one patient in the one-bar group, p = 1.000). Our study reveals that patients undergoing the Nuss Procedure for PE with two bars exhibit comparable clinical outcomes and QoL to those with one bar. However, patients with two bars may have higher levels of psychological well-being and satisfaction, indicating potential benefits associated with this approach. These findings suggest potential advantages of the two-bar approach, but further research with larger sample sizes is warranted to confirm these observations.

Clinical Outcome Comparison between CT-Guided Versus all MRI-Guided Scenarios in Brachytherapy for Cervical Cancer: A Single-Institute Experience

ObjectivesImage-guided adaptive brachytherapy (IGABT) is the standard of care for patients with cervical cancer. The objective of this study was to compare the treatment outcomes and adverse effects of computed tomography (CT)-guided and magnetic resonance imaging (MRI)-guided scenarios. Materials and MethodsData of patients with cervical cancer treated using external beam radiotherapy followed by IGABT from 2012 to 2016 were retrospectively reviewed. CT-guided IGABT was compared with the three modes of MRI-guided IGABT: pre-brachytherapy (MRI Pre-BT) without applicator insertion for fusion, planning MRI with applicator in-place in at least 1 fraction (MRI ≥1Fx), and MRI in every fraction (MRI EveryFx). Patient characteristics, oncologic outcomes, and late radiation toxicity were analyzed using descriptive, survival, and correlation statistics. ResultsOverall, 354 patients were evaluated with a median follow-up of 60 months. The 5-year overall survival (OS) rates were 61.5%, 65.2%, 54.4%, and 63.7% with CT-guided, MRI PreBT, MRI ≥1Fx, and MRI EveryFx IGABT, respectively with no significant differences (p = 0.522). The 5-year local control (LC) rates were 92.1%, 87.8%, 80.7%, and 76.5% (p = 0.133), respectively, with a significant difference observed between the CT-guided and MRI ≥1Fx (p = 0.018). The grade 3–4 late gastrointestinal toxicity rates were 6% in the CT-guided, MRI ≥1Fx, and MRI EveryFx, and 8% in MRI PreBT. The grade 3–4 late genitourinary toxicity rates were 4% in the CT-guided, 2% in MRI PreBT, 1% in MRI ≥1Fx, and none in MRI EveryFx. No significant differences were observed in the oncologic and toxicity outcomes among MRI PreBT, MRI ≥1Fx, and MRI EveryFx. ConclusionsCT-guided IGABT yielded an acceptable 5-year OS, LC, and toxicity profile compared with all MRI scenarios and is a potentially feasible option in resource-limited settings.

Development of artificial intelligence-driven biosignal-sensitive cardiopulmonary resuscitation robot

Aim of the studyWe evaluated whether an artificial intelligence (AI)-driven robot cardiopulmonary resuscitation (CPR) could improve hemodynamic parameters and clinical outcomes. MethodsWe developed an AI-driven CPR robot which utilizes an integrated feedback system with an AI model predicting carotid blood flow (CBF). Twelve pigs were assigned to the AI robot group (n = 6) and the LUCAS 3 group (n = 6). They underwent 6 min of CPR after 7 min of ventricular fibrillation. In the AI robot group, the robot explored for the optimal compression position, depth and rate during the first 270-second period, and continued CPR with the optimal setup during the next 90-second period and beyond. The primary outcome was CBF during the last 90-second period. The secondary outcomes were coronary perfusion pressure (CPP), end-tidal carbon dioxide level (ETCO2) and return of spontaneous circulation (ROSC). ResultsThe AI model’s prediction performance was excellent (Pearson correlation coefficient = 0.98). CBF did not differ between the two groups [estimate and standard error (SE), −23.210 ± 20.193, P = 0.250]. CPP, ETCO2 level and rate of ROSC also did not show difference [estimate and SE, −0.214 ± 7.245, P = 0.976 for CPP; estimate and SE, 1.745 ± 3.199, P = 0.585 for ETCO2; 5/6 (83.3%) vs. 4/6 (66.7%), P = 1.000 for ROSC). ConclusionThis study provides proof of concept that an AI-driven CPR robot in porcine cardiac arrest is feasible. Compared to a LUCAS 3, an AI-driven CPR robot produced comparable hemodynamic and clinical outcomes.

Single-bundle ACL combined with ALL reconstruction yields comparable outcomes in patients with varied anatomical risk factors for ACL graft failure

BackgroundAnterior cruciate ligament (ACL) graft failure is influenced by factors such as meniscal tears and tibial plateau slope. Combined anterior cruciate ligament (ACL) and anterolateral ligament (ALL) reconstruction has reduced failure rates; however, its efficacy in high-risk patients remains unclear. This study hypothesized that combined ACL and ALL reconstruction would yield similar clinical outcomes in patients with varying risks of ACL failure.Patients and methodsA total of 76 patients who underwent primary single-bundle ACL reconstruction combined with ALL reconstruction between June 2018 and June 2021 were included. The medial tibial slope (MTS), lateral tibial slope (LTS), and anterior tibial translation (ATT) were measured using magnetic resonance imaging and plain radiography of the knee joint. The meniscal lesions were assessed during surgery. Preoperative clinical assessments and final follow-up were conducted using patient-reported outcome measurements (PROMs), including the International Knee Documentation Committee (IKDC) evaluation, Lysholm knee scoring scale, and Tegner Activity scale. PROMs were collected at least two years postoperatively.ResultsThe average follow-up was 32.5 ± 7.4 months. There were no significant differences in postoperative IKDC score, Lysholm score, or Tegner activity score between patients with or without medial meniscus injury (p = 0.155, 0.914, and 0.042, respectively), with or without lateral meniscus injury (p = 0.737, 0.569, and 0.942, respectively), medial tibial slope > 12° or ≤ 12° (p = 0.290, 0.496, and 0.988, respectively), or lateral tibial slope > 7.4° or ≤ 7.4° (p = 0.213, 0.625, and 0.922, respectively). No significant correlations were found between anterior tibial translation and postoperative IKDC (R = -0.058, p = 0.365), Lysholm (R = -0.017, p = 0.459), or Tegner activity scores (R = -0.147, p = 0.189).ConclusionOur study demonstrates that single-bundle ACL reconstruction combined with ALL reconstruction provides reliable and comparable clinical outcomes in patients with high-risk factors for ACL graft failure, such as increased tibial slope or meniscal injury. Our results suggest that the indications for ALL reconstruction may be expanded to include patients with a high tibial slope or meniscal injury, because these factors have been shown to contribute to increased rotational instability and high rates of ACL graft failure. Future prospective randomized controlled trials with large patient cohorts and long follow-up periods are needed to validate these findings and establish clear guidelines for patient selection and surgical decision-making.Level of evidenceLevel 3.

Comparison of clinical and radiographic outcomes of bilateral versus unilateral ramus fixation in straddle fractures with posterior pelvic ring injury.

Superior and inferior ramus fractures, termed straddle fractures, are high-energy fractures often accompanied by unstable pelvic ring injuries. However, consensus is lacking regarding indications for surgical treatment or fixation methods. We aimed to compare clinical and radiological outcomes of unilateral ramus fixation (URF) and bilateral ramus fixation (BRF) for straddle fractures with unilateral posterior pelvic ring injuries. We enrolled 118 patients (73 males, 45 females; mean age, 47 years) diagnosed with straddle fractures between March 2015 and December 2021 with > 1 year of follow-up. Patients were divided into URF (n = 60) and BRF (n = 58) groups based on the anterior pelvic ring fixation method. Preoperative factors including body mass index, diabetes, smoking, injury mechanism, injury severity score, American Society of Anesthesiologists classification system, Tile classification, and Young and Burgess classification were compared. Intraoperative blood loss, operation time, postoperative bone union rate, complications, and the need for additional surgeries were analyzed. There were no statistically significant preoperative differences between the two groups. However, the URF group showed a significantly lower mean operative time and blood transfusion requirement (63min and 2 units, respectively) than the BRF group (104min and 3 units, respectively) (both p < 0.001). Postoperatively, bone union was achieved in 57 (95.0%) and 56 (96.6%) patients in the URF and BRF groups, respectively. Complications occurred in 17 (28.3%) and 14 (24.1%) patients in the URF and BRF groups, respectively, with additional surgeries needed in 3 (5.0%) patients in the URF group and 2 (3.4%) patients in the BRF group. Unilateral anterior fixation can provide sufficient stability and clinical effectiveness in the surgical treatment of straddle fractures in areas with posterior pelvic ring injuries. Compared with bilateral anterior fixation, unilateral fixation significantly reduces operation time and blood loss, making it a viable fixation method for straddle fractures.

Comparison of clinical outcomes of anterior combined latissimus dorsi and teres major tendon transfer for anterior superior irreparable rotator cuff tear between young and elderly patients.

Anterior combined latissimus dorsi and teres major (aLDTM) tendon transfer has shown promise as a treatment for anterior superior irreparable rotator cuff tears (ASIRCTs). Our study aimed to compare aLDTM clinical outcomes for ASIRCTs between young and elderly patients. This retrospective study reviewed data from patients who underwent aLDTM tendon transfer for ASIRCTs with minimum 2-year follow-up. Clinical evaluations included visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE), active range of motion (aROM), strength, and complications. Radiologic assessments included acromiohumeral distance, Hamada classification, and integrity of transferred tendon. Patients were divided into group total (all ages), group old (≥70 years), and group young (≤60 years). A total of 123 patients were enrolled with 39 in group young (mean age, 56.6±4.9 years) and 27 in group old (mean age, 73.6±2.3 years). Postoperatively, both groups showed significant improvements in VAS, ASES, and SANE scores and improved aROM for forward elevation, abduction, and internal rotation. No significant differences in clinical coutcomes were noted between the groups. Furthermore, similar rates of complications, including retears and postoperative infections, were observed across all three groups. Our study highlights the effectiveness of aLDTM transfer for ASIRCTs with minimal glenohumeral arthritis, demonstrating similar outcomes in both group young and group old patients. Moreover, patients in these distinct age groups showed comparable clinical results when compared to group total. Level of evidence: III.

Comparison of Clinical Outcomes Between Antegrade and Retrograde Techniques for Chronic Total Occlusion Revascularizations: A Systematic Review and Meta-Analysis.

Chronic total occlusions (CTOs) present significant challenges in interventional cardiology. This meta-analysis aims to compare the efficacy and safety of retrograde versus antegrade techniques in CTO percutaneous coronary intervention (PCI). A systematic review and meta-analysis were conducted following PRISMA guidelines. Electronic databases were searched through June 20, 2024. Studies comparing outcomes between antegrade and retrograde methods for CTO-PCI were included. Primary outcomes were procedural and technical success. Secondary outcomes included major adverse cardiac events (MACE), all-cause mortality, and myocardial infarction. The final analysis included seventeen studies. The antegrade approach showed a 5% higher likelihood of technical success (OR: 1.05, 95% CI: 1.02-1.09) and 14% higher odds of procedural success (OR: 1.14, 95% CI: 1.10-1.19) compared to the retrograde approach. The antegrade group also demonstrated lower risks of MACE, all-cause mortality, and myocardial infarction (RR: 0.40, 95% CI: 0.26-0.63). This meta-analysis suggests that the antegrade approach in CTO-PCI is associated with higher success rates and lower risks of adverse outcomes compared to the retrograde approach. However, the retrograde technique remains crucial for complex lesions and patients with multiple comorbidities.

Comparison of clinical and echocardiographic outcomes between mini-thoracotomy transatrial LuX-Valve transcatheter and surgical tricuspid valve replacement.

Transcatheter tricuspid valve replacement (TTVR) has recently emerged as a novel therapeutic approach for managing severe tricuspid regurgitation (TR). However, surgical tricuspid valve replacement (STVR) continues to be the predominant treatment modality. There are limited comparative data on both procedures. This study aimed to compare clinical and echocardiographic outcomes between patients who underwent mini-thoracotomy transatrial LuX-Valve TTVR and those who underwent STVR. This study prospectively collected patients with severe TR who underwent TTVR (n = 29) or isolated STVR (n = 59) at Wuhan Union Hospital from 2019 to 2022. All TTVR patients received the LuX-Valve via a mini-thoracotomy and transatrial approach. The clinical and echocardiographic outcomes were compared at 30-day and one-year follow-ups. At baseline, patients with LuX-Valve TTVR had higher surgical risk scores and a greater proportion of right ventricular dysfunction compared with STVR. In the early postoperative period, the STVR group had a greater decrease in right ventricular function. Hospital length of stay (LOS), intensive care unit LOS, total procedure time, and tracheal intubation time were shorter in the TTVR than in the STVR group. The incidence of postoperative paravalvular leaks was higher among patients who underwent TTVR. Compared to the STVR group, the pacemaker implantation rate was lower in the TTVR group. During follow-up, the peak tricuspid valve velocity and mean gradient in the TTVR group were consistently lower than those in the STVR group. There was similar mortality between TTVR and STVR at 30-day and one-year follow-ups. The mini-thoracotomy transatria LuX-Valve TTVR has a higher incidence of paravalvular leaks and a lower rate of pacemaker implantation than STVR, with similar 30-day and one-year mortality rates. In some respects, mini-thoracotomy transatrial LuX-Valve TTVR may be a feasible and safe treatment option for specific populations, or it could potentially serve as an alternative therapy to supplement conventional STVR. Further follow-up is required to assess differences in long-term clinical outcomes and valve durability.
