Routine Versus Selective Distal Perfusion Catheter Use in Venoarterial Extracorporeal Membrane Oxygenation

Although current studies support the use of prophylactic distal perfusion catheters (DPCs) to decrease limb ischemia in patients on venoarterial extracorporeal membrane oxygenation (VA ECMO), methods for monitoring limb ischemia differ between studies. We evaluated the safety of a selective rather than prophylactic DPC strategy at a single center with a well-established protocol for limb ischemia monitoring. Distal perfusion catheters were placed selectively if there was evidence of hypoperfusion at any point until decannulation. All patients were followed daily by vascular surgery with continuous regional saturation monitoring. Of 188 patients supported with VA ECMO, there were no significant differences in baseline characteristics between patients with upfront, delayed, and no DPC. Thirty day mortality was highest in patients with an upfront DPC (56% in the upfront DPC group, 19% in the delayed DPC group, and 22% in the no-DPC group, p < 0.001). The incidence of major bleeding, fasciotomy, and amputation in the entire cohort was 3.7%, 3.7%, and 0%, respectively. With strict adherence to a protocol for limb ischemia monitoring, a selective rather than prophylactic DPC strategy is safe and may obviate the risks of an additional arterial catheter.

High-frequency low-tidal volume ventilation improves procedural and long-term clinical outcomes in persistent atrial fibrillation ablation: Prospective multicenter registry

BackgroundHigh-frequency, low-tidal volume (HFLTV) ventilation increases the efficacy and efficiency of radiofrequency catheter ablation (RFCA) of paroxysmal atrial fibrillation. Whether those benefits can be extrapolated to RFCA of persistent atrial fibrillation (PeAF) is undetermined. ObjectiveThe purpose of this study was to evaluate whether using HFLTV ventilation during RFCA in patients with PeAF is associated with improved procedural and long-term clinical outcomes compared to standard ventilation (SV). MethodsIn this prospective multicenter registry (REAL-AF), patients who had undergone pulmonary vein isolation (PVI) + posterior wall isolation (PWI) for PeAF using either HFLTV ventilation or SV were included. The primary efficacy outcome was freedom from all-atrial arrhythmias at 12 months. Secondary outcomes included procedural and long-term clinical outcomes and complications. ResultsA total of 210 patients were included (HFLTV=95 vs. SV=115) in the analysis. There were no differences in baseline characteristics between the groups. Procedural time (80 [66–103.5] minutes vs 110 [85–141] minutes; P <.001), total radiofrequency (RF) time (18.73 [13.93–26.53] minutes vs 26.15 [20.30–35.25] minutes; P <.001), and pulmonary vein RF time (11.35 [8.78–16.69] minutes vs 18 [13.74–24.14] minutes; P <.001) were significantly shorter using HFLTV ventilation compared with SV. Freedom from all-atrial arrhythmias was significantly higher with HFLTV ventilation compared with SV (82.1% vs 68.7%; hazard ratio 0.41; 95% confidence interval [0.21–0.82]; P = .012), indicating a 43% relative risk reduction and a 13.4% absolute risk reduction in all-atrial arrhythmia recurrence. There was no difference in long-term procedure-related complications between the groups (HFLTV 1.1% vs SV 0%, P = .270). ConclusionIn patients undergoing RFCA with PVI + PWI for PeAF, the use of HFLTV ventilation was associated with higher freedom from all-atrial arrhythmias at 12-month follow-up, with significantly shorter procedural and RF times compared to SV, while reporting a similar safety profile.

Evaluation of pathologic response and surgical safety of total neoadjuvant therapy for patients with clinical stage III gastric cancer in a real-world setting

BackgroundPerioperative chemotherapy is the standard treatment for locally advanced gastric cancer. However, the potential benefit of extending therapy before surgery remains largely unknown. In this study, we aimed to evaluate the efficacy and safety of total neoadjuvant chemotherapy, with or without immune checkpoint blockade. MethodsA cohort of 174 patients with clinical stage III gastric cancer who underwent D2 gastrectomy from October 2021 to March 2024 in the real-world setting were included in this study. Among these patients, 101 were treated with total neoadjuvant therapy (TNT) and 73 were treated with perioperative neoadjuvant therapy (PNT). We compared the pathologic complete response (pCR) rate, ypN0 rate, recurrence-free survival (RFS), overall survival (OS), and postoperative complications between the 2 groups. Multivariate logistic regression analysis was conducted to identify factors associated with pCR or ypN0. ResultsCompared with the PNT group, the patients in the TNT group were more frequently treated with intensive chemotherapy with triplets + immunotherapy. Apart from this, there were no significant differences in baseline characteristics. There were no statistically significant differences in pCR (16.8% vs 12.3%), ypN0 (49.5% vs 38.4%), RFS, OS, and postoperative complications (27.7% vs 26.0%) between the TNT and PNT groups. Older age, diffuse type, and stable disease/progressive disease based on clinical efficacy evaluation were independently associated with non-pCR. Stable disease/progressive disease, linitis plastica, and poor differentiation were independently associated with ypN+. Neither the number of neoadjuvant therapy cycles nor the specific regimens were associated with pCR or ypN0. In the subgroup analysis of patients receiving total gastrectomy, there were still no statistically significant differences in pCR (16.7% vs 2.6%), ypN0 (43.8% vs 39.5%), and postoperative complications (45.8% vs 36.8%) between the 2 groups. ConclusionAlthough TNT did not increase the postoperative complication rate, it also did not provide any additional short-term benefits compared with PNT for clinical stage III gastric cancer.

Real-world effectiveness of dupilumab versus benralizumab and mepolizumab.

Introduction: In the United States, this real-world study compared the effectiveness of dupilumab, benralizumab, and mepolizumab in reducing exacerbations and systemic corticosteroid (SCS) prescriptions among patients with asthma. Methods: Patients (≥12 years old) who initiated dupilumab, benralizumab, or mepolizumab (index) between November 2018 and September 2020 were identified by using electronic medical record data. Subjects were included if they had ≥ 12 months of data before and after the index date and two or more severe asthma-related exacerbations before the index date. Differences in baseline characteristics were addressed by using inverse probability treatment weighting (IPTW). Pairwise comparisons between dupilumab and benralizumab, or mepolizumab were conducted by using negative binomial regression, adjusting for baseline rates and unbalance characteristics (≥10% standardized differences) after IPTW. Results: Overall, a total of 1737 subjects met all criteria: 825 dupilumab, 461 benralizumab, and 451 mepolizumab initiators. In the postindex period, dupilumab was associated with a 24% and 28% significant reduction in the risk of severe asthma exacerbations versus benralizumab (incidence rate ratio [IRR] 0.76 [95% confidence interval {CI}, 0.67-0.86)] and mepolizumab (IRR 0.72 [95% CI, 0.63-0.82]), respectively. In addition, dupilumab treatment significantly reduced SCS prescriptions by 16% and 25% versus benralizumab and mepolizumab, respectively (p < 0.05). Conclusion: This study represents one of the largest real-world comparisons of biologics (dupilumab, benralizumab, and mepolizumab) for asthma in the United States to date. This analysis shows that the use of dupilumab was associated with a significantly greater reduction in both severe asthma exacerbations and SCS prescriptions compared with benralizumab and mepolizumab.

COVID-19 Vaccination in the First Trimester and Major Structural Birth Defects Among Live Births

COVID-19 vaccination is recommended throughout pregnancy to prevent pregnancy complications and adverse birth outcomes associated with COVID-19 disease. To date, data on birth defects after first-trimester vaccination are limited. To evaluate the associated risks for selected major structural birth defects among live-born infants after first-trimester receipt of a messenger RNA (mRNA) COVID-19 vaccine. This was a retrospective cohort study of singleton pregnancies with estimated last menstrual period (LMP) between September 13, 2020, and April 3, 2021, and ending in live birth from March 5, 2021, to January 25, 2022. Included were data from 8 health systems in California, Oregon, Washington, Colorado, Minnesota, and Wisconsin in the Vaccine Safety Datalink. Receipt of 1 or 2 mRNA COVID-19 vaccine doses in the first trimester, as part of the primary series. Selected major structural birth defects among live-born infants, identified from electronic health data using validated algorithms, with neural tube defects confirmed via medical record review. Among 42 156 eligible pregnancies (mean [SD] maternal age, 30.9 [5.0] years) 7632 (18.1%) received an mRNA COVID-19 vaccine in the first trimester. Of 34 524 pregnancies without a first-trimester COVID-19 vaccination, 2045 (5.9%) were vaccinated before pregnancy, 13 494 (39.1%) during the second or third trimester, and 18 985 (55.0%) were unvaccinated before or during pregnancy. Compared with pregnant people unvaccinated in the first trimester, those vaccinated in the first trimester were older (mean [SD] age, 32.3 [4.5] years vs 30.6 [5.1] years) and differed by LMP date. After applying stabilized inverse probability weighting, differences in baseline characteristics between vaccinated and unvaccinated pregnant persons in the first trimester were negligible (standardized mean difference <0.20). Selected major structural birth defects occurred in 113 infants (1.48%) after first-trimester mRNA COVID-19 vaccination and in 488 infants (1.41%) without first-trimester vaccine exposure; the adjusted prevalence ratio was 1.02 (95% CI, 0.78-1.33). In secondary analyses, with major structural birth defect outcomes grouped by organ system, no significant differences between infants vaccinated or unvaccinated in the first trimester were identified. In this multisite cohort study, among live-born infants, first-trimester mRNA COVID-19 vaccine exposure was not associated with an increased risk for selected major structural birth defects.

Construction and Validation of a Predictive Model for Coronary Artery Disease Using Extreme Gradient Boosting.

Early recognition of coronary artery disease (CAD) could delay its progress and significantly reduce mortality. Sensitive, specific, cost-efficient and non-invasive indicators for assessing individual CAD risk in community population screening are urgently needed. 3112 patients with CAD and 3182 controls were recruited from three clinical centers in China, and differences in baseline and clinical characteristics were compared. For the discovery cohort, the least absolute shrinkage and selection operator (LASSO) regression was used to identify significant features and four machine learning algorithms (logistic regression, support vector machine (SVM), random forest (RF) and extreme gradient boosting (XGBoost)) were applied to construct models for CAD risk assessment, the receiver operating characteristics (ROC) curve and precision-recall (PR) curve were conducted to evaluate their predictive accuracy. The optimal model was interpreted by Shapley additive explanations (SHAP) analysis and assessed by the ROC curve, calibration curve, and decision curve analysis (DCA) and validated by two external cohorts. Using LASSO filtration, all included variables were considered to be statistically significant. Four machine learning models were constructed based on these features and the results of ROC and PR curve implied that the XGBoost model exhibited the highest predictive performance, which yielded a high area of ROC curve (AUC) of 0.988 (95% CI: 0.986-0.991) to distinguish CAD patients from controls with a sensitivity of 94.6% and a specificity of 94.6%. The calibration curve showed that the predicted results were in good agreement with actual observations, and DCA exhibited a better net benefit across a wide range of threshold probabilities. External validation of the model also exhibited favorable discriminatory performance, with an AUC, sensitivity, and specificity of 0.953 (95% CI: 0.945-0.960), 89.9%, and 87.1% in the validation cohort, and 0.935 (95% CI: 0.915-0.955), 82.0%, and 90.3% in the replication cohort. Our model is highly informative for clinical practice and will be conducive to primary prevention and tailoring the precise management for CAD patients.

Efficacy of avalglucosidase alfa on forced vital capacity percent predicted in treatment-naïve patients with late-onset Pompe disease: A pooled analysis of clinical trials

BackgroundThe efficacy of avalglucosidase alfa (AVA) versus alglucosidase alfa (ALG) on forced vital capacity percent predicted (FVCpp) in patients with late-onset Pompe disease (LOPD) has been assessed in the Phase 3 COMET trial (NCT02782741). Due to the rarity of LOPD and thus small sample size in COMET, additional data were analyzed to gain further insights into the efficacy of AVA versus ALG. MethodsData from treatment-naive patients with LOPD were pooled from COMET and Phase 1/2 NEO1/NEO-EXT (NCT01898364/NCT02032524) trials for patients treated with AVA, and Phase 3 LOTS trial (NCT00158600) for patients treated with ALG. Regression analyses using mixed models with repeated measures consistent with those pre-specified in COMET were performed post-hoc. Analyses were adjusted for trials and differences in baseline characteristics. Four models were developed: Model 1 considered all trials; Model 2 included Phase 3 trials; Model 3 included Phase 3 trials and was adjusted for baseline ventilation use; Model 4 included COMET and NEO1/NEO-EXT (i.e., AVA trials only). ResultsOverall, 100 randomized patients from COMET (AVA, n = 51, ALG, n = 49), 60 from LOTS (ALG arm only), and three patients from NEO1/NEO-EXT (who received open-label AVA only) were considered for analysis. Mean age at enrollment was similar across trials (45.3–50.3 years); however, patients from LOTS had a longer mean duration of disease versus COMET and NEO1/NEO-EXT trials (9.0 years and 0.5–2.2 years, respectively) and younger mean age at diagnosis (36.2 years and 44.7–48.6 years, respectively). Least squares mean (95% confidence interval) improvement from baseline in FVCpp at Week 49–52 for AVA versus ALG was 2.43 (−0.13; 4.99) for COMET (n = 98); 2.31 (0.06; 4.57) for Model 1 (n = 160); 2.43 (0.21; 4.65) for Model 2 (n = 157); 2.80 (0.54; 5.05) for Model 3 (n = 154); and 2.27 (−0.30; 4.45) for Model 4 (n = 101). ConclusionsModels 1 to 3, which had an increased sample size versus COMET, demonstrated a nominally significant effect on FVCpp favoring AVA versus ALG after 1 year of treatment, consistent with results from COMET.

Mid-Term Outcomes of Aortic Valve Repair Without Aortic Root Replacement: A Single-Center Experience.

Background Aortic valve (AV) repair is a challenging procedure due to its complexity, lower reproducibility, and steep learning curve. To examine its durability and validity, we investigated mid-term outcomes following AV repair without aortic root replacement. Methods Between March 2007 and May 2018, we retrospectively identified 14 patients who underwent AV repair without aortic root replacement at our institution. We investigated their baseline characteristics and postoperative outcomes, including the reoperation rate due to aortic regurgitation (AR) recurrence. Furthermore, we divided them into two groups: those who required reoperation due to AR recurrence (Group R) and those who did not require reoperation (Group F), and statistically compared them. Results The median age was 52.5 years (IQR: 42.0-60.8), with 11 male patients (78.6%). Eight patients (57.1%) had a bicuspid AV. Five cases (35.7%) underwent reoperation due to AR recurrence during a median follow-up period of 5.5 years. There were no significant differences in baseline characteristics between Group R (n=5, 35.7%) and Group F (n=9, 64.3%), including AR etiology, AV repair procedure, and intraoperative AR grade after the final declamp. All cases in Group R had at least mild to moderate AR on the echocardiogram before discharge. Regarding the AR grade before discharge, Group R had a significantly higher grade than Group F (p = 0.013). Conclusions The indication for AV repair for AR might need to be reassessed due to the considerable mid-term reoperation rate. Cases of AV repair with more than mild AR at discharge should be carefully monitored, as they are likely to require future reoperation for AR.

Relationship Between Mild Cognitive Impairment and Activities of Daily Living in Older Patients in Convalescent Rehabilitation Wards

Aims Rehabilitation is commonly used in older patients with mild cognitive impairment (MCI). This study aimed to determine whether MCI affects the effectiveness of rehabilitation in older patients. Methods This was a retrospective cohort study of patients who received rehabilitation in convalescent rehabilitation wards (CRW) in Japan between January 2021 and December 2022. Results 141 patients who met inclusion criteria were included in this study. The patients were divided into MCI and non-MCI groups based on the Mini Mental State Examination score. At admission, MCI patients were significantly older, and had longer hospital stays, malnutrition, lower grip strength, and lower motor independence measures (FIMS) scores. After propensity score matching to adjust for differences in baseline characteristics, motor FIMS scores at discharge remained lower in the MCI group. Conclusions The presence of MCI is associated with ADL at discharge in older adults admitted to a CRW for rehabilitation.

Modified craniotomy procedures and virtual reality technology for accurate localization of the frontal branch of MMA in revascularization surgery

The frontal branch of middle meningeal artery (MMA) can easily be damaged during revascularization surgery. To precise locate it and minimize its injury, we propose a set of modified craniotomy procedures combined with simple virtual reality (VR) technology based on three-dimensional (3D) Slicer simply, economically, and efficiently. Patients with Moyamoya disease (MMD) and internal carotid artery occlusion (ICAO) who received revascularization from January 2015 to December 2022 were divided into two groups based on the methods used to locate the MMA: traditional methods and precise MMA locating with VR technology. Patient demographics and clinical characteristics were analyzed to compare the preservation rates of MMA. The distances between this artery and bony anatomical landmarks were also measured to better understand its localization. There was no significant difference in baseline characteristics between the two groups. The precise MMA locating group exhibited a significantly higher preservation rate of the frontal branch of MMA (p = 0.037, 91.7% vs. 68.2%). Over 77% of patients had their frontal branch of MMA partially or completely surrounded by bony structures to varying degrees. Therefore, the combination of modified craniotomy procedures, 3D Slicer, and simple VR technology represents an economical, efficient, and operationally simple strategy.

Patients Engaged in Losing Weight Preoperatively Experience Improved Outcomes After Hiatal Hernia Repair.

Adherence to preoperative weight loss recommendations may serve as a surrogate for the level of engagement in hiatal hernia (HH) patients. This study aims to evaluate the relationship between achieving preoperative weight loss goals and outcomes after HH repair. A retrospective review of 235 patients undergoing laparoscopic HH repair at a single institution was performed. Patients were grouped based on the percentage of weight loss goal achieved. Low achievement was defined as the bottom quartile of goal achievement (≤75%); high achievement was defined as the top quartile (≥140%). Baseline characteristics, clinical outcomes, and patient reported outcomes (PROMs) were compared between groups. 131/235 (55.7%) achieved their weight loss goal. No differences in baseline characteristics or clinical outcomes were observed between the low and high achievement groups. While both groups experienced improvements in PROMs postoperatively, patients in the high achievement group demonstrated significantly lower symptom burden at one-month postoperatively. Further, high-achievement patients were more likely to experience complete resolution of common HH symptoms at one-month postoperatively, including no difficulty swallowing food, no breathing difficulties or choking episodes, no choking when eating food, no choking when drinking liquid, and no regurgitation of food or liquid. In patients undergoing laparoscopic HH repair, patients achieving their preoperative weight loss goals experienced less overall symptom burden and lower prevalence of common symptoms one-month postoperatively than those with low levels of goal achievement. These results demonstrate that patients can take an active role in improving their own surgical outcomes and health status.

Survival analysis for patients with metachronous contralateral breast cancer: Insights from a retrospective study.

Continued advances in the diagnosis and treatment of breast cancer (BC) have led to an increase in the number of long-term BC survivors and an increase in the incidence of metachronous BC in the contralateral breast. Therefore, it is important to understand the factors that influence the development of metachronous BC; however, the impact of the laterality of the initial ipsilateral (I)BC as a risk factor for the development of metachronous contralateral (MC)BC has not been extensively investigated. The present study included 17,082 female patients with stage 0-3 IBC from the prospectively maintained Korean Breast Cancer Registry from 1989-2013 and divided them into two groups: Patients with MCBC (n=88) and those without MCBC (n=16,994). Risk factors that present at the initial BC diagnosis that could significantly influence the development of MCBC were screened for and risks were evaluated using the Fine-Gray subdistribution hazard model. Significant differences in baseline characteristics between MCBC and non-MCBC groups were demonstrated. Patients aged <40 years, those with histological and nuclear grade 3 tumors, and those with the triple-negative BC subtype were significantly more prevalent in the MCBC group than in the non-MCBC group. Additionally, the cumulative incidence of MCBC increased over time, with a notable increase from 0.1% in year 1 to 1.6% in year 10. Survival analysis revealed no significant differences in overall or BC-specific survival between the two groups. Key predictive factors identified for MCBC included an age of <40 years at initial diagnosis, a negative progesterone receptor status, and a Ki-67 score of >14%. Overall, the present study revealed several factors associated with MCBC and emphasized the need for long-term monitoring of BC survivors, considering these newly identified risk factors.

Epidemiological exploration of the impact of bluetooth headset usage on thyroid nodules using Shapley additive explanations method

With an increasing prevalence of thyroid nodules globally, this study investigates the potential correlation between the use of Bluetooth headsets and the incidence of thyroid nodules, considering the cumulative effects of non-ionizing radiation (NIR) emitted by these devices. In this study, we analyzed 600 valid questionnaires from the WenJuanXing platform using Propensity Score Matching (PSM) and the XGBOOST model, supplemented by SHAP analysis, to assess the risk of thyroid nodules. PSM was utilized to balance baseline characteristic differences, thereby reducing bias. The XGBOOST model was then employed to predict risk factors, with model efficacy measured by the area under the Receiver Operating Characteristic (ROC) curve (AUC). SHAP analysis helped quantify and explain the impact of each feature on the prediction outcomes, identifying key risk factors. Initially, 600 valid questionnaires from the WenJuanXing platform underwent PSM processing, resulting in a matched dataset of 96 cases for modeling analysis. The AUC value of the XGBOOST model reached 0.95, demonstrating high accuracy in differentiating thyroid nodule risks. SHAP analysis revealed age and daily Bluetooth headset usage duration as the two most significant factors affecting thyroid nodule risk. Specifically, longer daily usage durations of Bluetooth headsets were strongly linked to an increased risk of developing thyroid nodules, as indicated by the SHAP analysis outcomes. Our study highlighted a significant impact relationship between prolonged Bluetooth headset use and increased thyroid nodule risk, emphasizing the importance of considering health impacts in the use of modern technology, especially for devices like Bluetooth headsets that are frequently used daily. Through precise model predictions and variable importance analysis, our research provides a scientific basis for the formulation of public health policies and personal health habit choices, suggesting that attention should be paid to the duration of Bluetooth headset use in daily life to reduce the potential risk of thyroid nodules. Future research should further investigate the biological mechanisms of this relationship and consider additional potential influencing factors to offer more comprehensive health guidance and preventive measures.

Retrospective Analysis of Aberrant Hepatic Artery in 1250 Patients with Hepatocellular Carcinoma Undergoing Transarterial Chemoembolization.

Aberrant hepatic artery is particularly common, and its diversity and complexity play a critical role in surgery. The aim of this study was to describe the incidence and type of aberrant hepatic artery, and to compare differences in transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC) with vs without aberrant hepatic artery. This was a retrospective study of patients with HCC who received TACE at the same intervention center between March 15, 2020 and December 31, 2022. All patients who met inclusion criteria were divided into two groups based on whether or not they had aberrant hepatic artery. The aberrant hepatic artery was systematically classified according to variations in origin. We compared differences in baseline characteristics, operation duration, and postoperative hospitalization between the two groups. Postoperative adverse events and laboratory data were also compared. A total of 1250 patients hospitalized with HCC were included in the study (mean age, 58 ± 10 years, 1019 [81.5%] males). A high incidence of aberrant hepatic artery was found during TACE (21.3%, 266 of 1250), mainly involving a single variation of the aberrant left hepatic artery (aLHA) (6.1%, 76 of 1250) or aberrant right hepatic artery (aRHA) (10.9%, 136 of 1250) origin, as well as complex variations of the aLHA and aRHA origin (2.4%, 30 of 1250). When comparing patients with vs without aberrant hepatic artery, the TACE operation duration was significantly different (p < 0.001), and tended to be greater for patients with aberrant hepatic artery. In addition, differences between aberrant and normal hepatic artery groups in postoperative nausea and vomiting were statistically significant (40.2% vs 30.8%, respectively, p = 0.004). Postoperative laboratory examinations revealed significant differences in aspartate aminotransferase, alanine aminotransferase, and neutrophil percentage between the two groups (p < 0.05). The incidence of aberrant hepatic artery is extremely high, and the condition is characterized by complex variations. Moreover, aberrant hepatic artery may have a critical impact on the course of TACE treatment.

Comparative on the effectiveness and safety of different carotid endarterectomy techniques: a single-center Retrospective Study

BackgroundCarotid endarterectomy (CEA) is a surgical procedure that can reduce the risk of stroke in patients with carotid artery stenosis. However, controversy still exists regarding the optimal surgical technique for CEA.ObjectiveTo compare the safety and effectiveness of different techniques.MethodsData on baseline characteristics as well as perioperative and postoperative complications from patients who underwent CEA at the Department of Vascular Surgery, Xuanwu Hospital, Capital Medical University, were retrospectively collected and analyzed.ResultsA total of 262 CEA patients included in study, with a total of 265 CEA operations. The mean age of 69.95 ± 7.29 (range, 44–89) years. 65 (24.5%) patients underwent cCEA, 94 (35.5%) underwent pCEA, and 106 (40.0%) underwent eCEA. The use of shunt (1.9%) and the mean operation time were lower in eCEA group (P < 0.05). eCEA was also associated with a lower incidence of postoperative hypotension, whereas pCEA was associated with a lower incidence of postoperative hypertension (P < 0.05). There was no significant difference in clinical baseline characteristics, occurrence of perioperative complications, and survival whether restenosis-free, asymptomatic or overall.ConclusionsThis study found that all three surgical methods are equally safe for the treatment of carotid artery stenosis and are effective in preventing stroke.

Risk of acute kidney injury following contrast-enhanced CT or MRI in a cohort of 3061 hospitalized children in China

ObjectivesTo compare the risk of acute kidney injury (AKI) between hospitalized children who received intravenous contrast media for imaging examinations and those who did not.MethodsThis retrospective cohort study enrolled patients aged 0–18 years with serum creatinine levels before and after imaging examinations from 2015 to 2020 at Beijing Children’s Hospital. Participants were classified into an exposure group or a control group. Log-binomial regression analysis was used to estimate the adjusted risk ratio (aRR) value for the association between exposure to contrast media and consequential AKI. After which, inverse probability treatment weighting was used to reduce systematic differences in baseline characteristics among the groups. Moreover, subgroup and sensitivity analyses were performed. Finally, multivariate logistic regression analysis was performed to identify risk factors for pediatric AKI.ResultsIn total, 3061 pediatric patients were included in the analyses (median age, 4.5 [IQR, 1.3–8.9] years, 1760 males). According the KDIGO definition of AKI, the incidence of AKI in the exposure group, and the control group were 7.4% and 6.5%, respectively; furthermore, the aRR was 1.35 (95% CI: 1.31–1.39). In patients underwent CT, the risk of AKI in the exposure group of contrast media increased compared with the control group and the aRR was 1.39 (95% CI: 1.09–1.78). However, it is not observed in patients underwent MRI (aRR: 1.36; 95% CI: 0.96–1.95). According to our subgroup analysis of pediatric patients aged ≥ 2 years (aRR: 1.38; 95% CI: 1.05–1.82) and sensitivity analysis (aRR: 1.32, 95% CI: 1.08–1.61), the risk of AKI in the exposure group was greater than that in the control group. An increased risk to exposure to contrast media was seen in females (aRR: 1.41, 95% CI: 1.05–1.89) rather than males (aRR: 1.30, 95% CI: 0.99–1.70). According to the multivariate logistic regression analyses, the baseline eGFR (OR: 1.02; 95% CI: 1.01–1.03) and comorbidities (OR: 2.97; 95% CI: 1.89–4.65) were risk factors, while age (OR: 0.87; 95% CI: 0.84–0.91) was a protective factor against AKI.ConclusionThe evidence from the present study suggested that the increased risk of AKI in hospitalized children induced by intravascular contrast should not be ignored.

A novel approach to treating post-stroke depression: administration of Botulinum Toxin A via local facial injection.

Post-stroke depression (PSD) is a frequent complication following a stroke, characterized by prolonged feelings of sadness and loss of interest, which can significantly impede stroke rehabilitation, increase disability, and raise mortality rates. Traditional antidepressants often have significant side effects and poor patient adherence, necessitating the exploration of more suitable treatments for PSD. Previous researchers and our research team have discovered that Botulinum Toxin A (BoNT-A) exhibits antidepressant effects. Therefore, our objective was to assess the efficacy and side effects of BoNT-A treatment in patients with PSD. A total of 71 stroke patients meeting the inclusion criteria were allocated to the two group. 2 cases were excluded due to severe neurological dysfunction that prevented cooperation and 4 cases were lost follow-up. Ultimately, number of participants in the BoNT-A group (n = 32) and Sertraline group (n = 33). Treatment efficacy was evaluated 1, 2, 4, 8 and 12 weeks post-treatment. There were no significant differences in baseline characteristics between the two groups (p > 0.05). Both groups exhibited comparable treatment efficacy, with fewer side effects observed in the BoNT-A group compared to the Sertraline group. BoNT-A therapy demonstrated significant effects as early as the first week (p < 0.05), and by the 12th week, there was a notable decrease in neuropsychological scores, significantly lower than the baseline level. The analysis revealed significant differences in measurements of the Hamilton Depression Scale (HAMD) (F(770) = 12.547, p = 0.000), Hamilton Anxiety Scale (HAMA) (F(951) = 10.422, p = 0.000), Self-Rating Depression Scale (SDS) (F(1385) = 10.607, p = 0.000), and Self-Rating Anxiety Scale (SAS) (F(1482) = 11.491, p = 0.000).

Efficacy and safety of two disposable circumcision suture devices for circumcision in adults: a prospective comparative multicenter study.

The objective of this study was to evaluate and compare efficacy and safety of two different Disposable circumcision suture devices (DCSDs). A prospective comparative non-randomized multicenter study was performed between November 2019 and February 2023. Patients underwent circumcision using a DCSD (CircCurerTM or the ZSR® device) according to the surgeon preference and device availability. A total of 378 patients were circumcised; 184 using CircCurerTM and 194 patients using ZSR®. No differences in baseline characteristics were observed. CircCurer and ZSR Groups showed similar rates of operative time (7.7 ±2.1 vs 7.3 ±2.0 min), surgical site infection (1.1% Vs 1.5%), edema (13% Vs 8.2%), hematomas (2.7% Vs 1.1%), and postoperative pain (2.5 Vs 2.0 points). ZSR Group had a significantly higher rate of clip fallout (62.9% Vs 38%, p < 0.001). At 2 months, patients of both groups reported a median satisfaction of 9 (8-9) points. Main limitation consist in non-randomized study. DCSDs seem to be effective and safe, with short operative times, uncommon and mild complications, and high patient satisfaction. ZSR® device has a higher rate of spontaneous staple dropout.

Outcomes of different pulmonary rehabilitation protocols in patients under mechanical ventilation with difficult weaning: a retrospective cohort study

BackgroundThe endeavor of liberating patients from ventilator dependence within respiratory care centers (RCCs) poses considerable challenges. Multiple factors contribute to this process, yet establishing an effective regimen for pulmonary rehabilitation (PR) remains uncertain. This retrospective study aimed to evaluate existing rehabilitation protocols, ascertain associations between clinical factors and patient outcomes, and explore the influence of these protocols on the outcomes of the patients to shape suitable rehabilitation programs.MethodsConducted at a medical center in northern Taiwan, the retrospective study examined 320 newly admitted RCC patients between January 1, 2015, and December 31, 2017. Each patient received a tailored PR protocol, following which researchers evaluated weaning rates, RCC survival, and 3-month survival as outcome variables. Analyses scrutinized differences in baseline characteristics and prognoses among three PR protocols: protocol 1 (routine care), protocol 2 (routine care plus breathing training), and protocol 3 (routine care plus breathing and limb muscle training).ResultsAmong the patients, 28.75% followed protocol 1, 59.37% protocol 2, and 11.88% protocol 3. Variances in age, body-mass index, pneumonia diagnosis, do-not-resuscitate orders, Glasgow Coma Scale scores (≤ 14), and Acute Physiology and Chronic Health Evaluation II (APACHE) scores were notable across these protocols. Age, APACHE scores, and abnormal blood urea nitrogen levels (> 20 mg/dL) significantly correlated with outcomes—such as weaning, RCC survival, and 3-month survival. Elevated mean hemoglobin levels linked to increased weaning rates (p = 0.0065) and 3-month survival (p = 0.0102). Four adjusted models clarified the impact of rehabilitation protocols. Notably, the PR protocol 3 group exhibited significantly higher 3-month survival rates compared to protocol 1, with odds ratios (ORs) ranging from 3.87 to 3.97 across models. This association persisted when comparing with protocol 2, with ORs between 3.92 and 4.22.ConclusionOur study showed that distinct PR protocols significantly affected the outcomes of ventilator-dependent patients within RCCs. The study underlines the importance of tailored rehabilitation programs and identifies key clinical factors influencing patient outcomes. Recommendations advocate prospective studies with larger cohorts to comprehensively assess PR effects on RCC patients.
