Decoding Molecular Mechanisms Underlying Outcomes After Ischemic Stroke Thrombectomy by RNA Sequencing of Retrieved Clots.

Transcriptomic profiling has emerged as a powerful tool for exploring the molecular landscape of ischemic stroke clots and providing insights into the pathophysiological mechanisms underlying stroke progression and recovery. In this study, we aimed to investigate the relationship between stroke clot transcriptomes and stroke thrombectomy outcome, as measured by early neurological improvement (ENI) 30 (i.e., a 30% reduction in NIHSS at 24 h post-thrombectomy). We hypothesized that there exist distinct clot gene expression patterns between good and poor neurological outcomes. Transcriptomic analysis of 32 stroke clots retrieved by mechanical thrombectomy was conducted. Transcriptome data of these clots were analyzed to identify differentially expressed genes (DEGs), defined as those with a log(fold-change) ≥ 1.5 and q < 0.05 between samples with good and poor early neurological outcomes. Gene ontology and bioinformatics analyses were performed on genes with p < 0.01 to identify enriched biological processes and Ingenuity Pathway Analysis canonical pathways. Moreover, AUC analysis assessed the predictive power of DEGs for 90-day function outcome (mRS ≤ 2) and cellular composition of clot was predicted using CIBERSORT. We also assessed whether differential enrichment of immune cell types could indicate patient survival. A total of 41 DEGs were identified. Bioinformatics showed that enriched biological processes and pathways emphasized the chronic immune response and matrix metalloproteinase inhibition. Moreover, 25 of the DEGs were found to be significant predictors of 90-day mRS. These genes were indicative of monocytes enrichment and neutrophil depletion in patients with poorer outcomes. Our study revealed a distinct gene expression pattern and dysregulated biological pathways associated with ENI. This expression pattern was also predictive of long-term outcome, suggesting a biological link between those ENIs and 90-day mRS.

Postnatal Brain Trajectories and Maternal Intelligence Predict Childhood Outcomes in Complex CHD.

Objective: To determine whether early structural brain trajectories predict early childhood neurodevelopmental deficits in complex CHD patients and to assess relative cumulative risk profiles of clinical, genetic, and demographic risk factors across early development. Study Design: Term neonates with complex CHDs were recruited at Texas Children's Hospital from 2005-2011. Ninety-five participants underwent three structural MRI scans and three neurodevelopmental assessments. Brain region volumes and white matter tract fractional anisotropy and radial diffusivity were used to calculate trajectories: perioperative, postsurgical, and overall. Gross cognitive, language, and visuo-motor outcomes were assessed with the Bayley Scales of Infant and Toddler Development and with the Wechsler Preschool and Primary Scale of Intelligence and Beery-Buktenica Developmental Test of Visual-Motor Integration. Multi-variable models incorporated risk factors. Results: Reduced overall period volumetric trajectories predicted poor language outcomes: brainstem ((β, 95% CI) 0.0977, 0.0382-0.1571; p = 0.0022) and white matter (0.0023, 0.0001-0.0046; p = 0.0397) at 5 years; brainstem (0.0711, 0.0157-0.1265; p = 0.0134) and deep grey matter (0.0085, 0.0011-0.0160; p = 0.0258) at 3 years. Maternal IQ was the strongest contributor to language variance, increasing from 37% at 1 year, 62% at 3 years, and 81% at 5 years. Genetic abnormality's contribution to variance decreased from 41% at 1 year to 25% at 3 years and was insignificant at 5 years. Conclusion: Reduced postnatal subcortical-cerebral white matter trajectories predicted poor early childhood neurodevelopmental outcomes, despite high contribution of maternal IQ. Maternal IQ was cumulative over time, exceeding the influence of known cardiac and genetic factors in complex CHD, underscoring the importance of heritable and parent-based environmental factors.

Early Outcomes in Patients With LVAD Undergoing Heart Transplant via Use of the SherpaPak Cardiac Transport System.

Heart transplant (HT) in recipients with left ventricular assist devices (LVADs) is associated with poor early post-HT outcomes, including primary graft dysfunction (PGD). As complicated heart explants in recipients with LVADs may produce longer ischemic times, innovations in donor heart preservation may yield improved post-HT outcomes. The SherpaPak Cardiac Transport System is an organ preservation technology that maintains donor heart temperatures between 4 °C and 8 °C, which may minimize ischemic and cold-induced graft injuries. This analysis sought to identify whether the use of SherpaPak versus traditional cold storage was associated with differential outcomes among patients with durable LVAD undergoing HT. Global Utilization and Registry Database for Improved Heart Preservation-Heart (NCT04141605) is a multicenter registry assessing post-HT outcomes comparing 2 methods of donor heart preservation: SherpaPak versus traditional cold storage. A retrospective review of all patients with durable LVAD who underwent HT was performed. Outcomes assessed included rates of PGD, post-HT mechanical circulatory support use, and 30-day and 1-year survival. SherpaPak (n=149) and traditional cold storage (n=178) patients had similar baseline characteristics. SherpaPak use was associated with reduced PGD (adjusted odds ratio, 0.56 [95% CI, 0.32-0.99]; P=0.045) and severe PGD (adjusted odds ratio, 0.31 [95% CI, 0.13-0.75]; P=0.009), despite an increased total ischemic time in the SherpaPak group. Propensity matched analysis also noted a trend toward reduced intensive care unit (SherpaPak 7.5±6.4 days versus traditional cold storage 11.3±18.8 days; P=0.09) and hospital (SherpaPak 20.5±11.9 days versus traditional cold storage 28.7±37.0 days; P=0.06) lengths of stay. The 30-day and 1-year survival was similar between groups. SherpaPak use was associated with improved early post-HT outcomes among patients with LVAD undergoing HT. This innovation in preservation technology may be an option for HT candidates at increased risk for PGD. URL: https://www.clinicaltrials.gov; Unique identifier: NCT04141605.

Proteomic Analysis of Primary Graft Dysfunction in Porcine Lung Transplantation Reveals Alveolar-Capillary Barrier Changes Underlying the High Particle Flow Rate in Exhaled Breath.

Primary graft dysfunction (PGD) remains a challenge for lung transplantation (LTx) recipients as a leading cause of poor early outcomes. New methods are needed for more detailed monitoring and understanding of the pathophysiology of PGD. The measurement of particle flow rate (PFR) in exhaled breath is a novel tool to monitor and understand the disease at the proteomic level. In total, 22 recipient pigs underwent orthotopic left LTx and were evaluated for PGD on postoperative day 3. Exhaled breath particles (EBPs) were evaluated by mass spectrometry and the proteome was compared to tissue biopsies and bronchoalveolar lavage fluid (BALF). Findings were confirmed in EBPs from 11 human transplant recipients. Recipients with PGD had significantly higher PFR [686.4 (449.7-8,824.0) particles per minute (ppm)] compared to recipients without PGD [116.6 (79.7-307.4) ppm, p = 0.0005]. Porcine and human EBP proteins recapitulated proteins found in the BAL, demonstrating its utility instead of more invasive techniques. Furthermore, adherens and tight junction proteins were underexpressed in PGD tissue. Histological and proteomic analysis found significant changes to the alveolar-capillary barrier explaining the high PFR in PGD. Exhaled breath measurement is proposed as a rapid and non-invasive bedside measurement of PGD.

Preparedness for adulthood among young adults with histories of out-of-home care

Young adults with histories of out-of-home care (OOHC) have poor early adult outcomes. Transitioning to adulthood takes preparation, coupled with support and resources. Few studies have examined these young adults’ perceptions of what helped them prepare for adulthood and how prepared they perceived they were to make the developmental transition to adulthood. This convergent mixed methods study builds knowledge surrounding preparedness among a sample of young adults with histories in OOHC ( N = 204). The study progressed in three phases. First, quantitative measures of preparedness were examined related to five critical areas of young adulthood: (1) employment, (2) education/training, (3) health care, (4) housing and (5) managing money. Results indicated that youth felt more prepared to manage their money and pursue employment than they felt prepared in the other areas. The second phase focused on qualitative interview data. Participants were asked, “What has been the most helpful thing in preparing you to live as an adult?” Open-ended responses were audiotaped, listened to by analysts, transcribed, and de-identified. Qualitative analysis followed a series of steps, centering constant comparison. Six themes (with sub-themes) emerged from the analysis of the data, namely (1) Forced independence; (2) The instructive role of mistakes; (3) Programs and services; (4) Family support; (5) Structure; and (6) Role models. Finally, analysts compared results of the quantitative and qualitative data and noted the data were convergent in suggesting that young adults feel somewhat more prepared around employment, managing money, and finances, in comparison to other areas. Implications are discussed.

Omniflow® II biosynthetic graft offers acceptable early and mid-term outcomes in redo surgery in patients with critical limb-threatening ischemia with no available autologous vein material.

In this study, the early and mid-term outcomes of Omniflow® II (LeMaitre Vascular, Inc., Burlington, MA, USA) biosynthetic graft in redo surgery in patients with critical limb-threatening ischemia (CLTI) with no available autologous vein material were investigated with the aim to compare the outcomes obtained in "de novo" surgery versus redo surgery. From January 2018 until December 2022, data of CLTI patients from 18 centers in Italy with no autologous vein material underwent infrainguinal bypass with Omniflow® II biosynthetic graft were collected. Thirty-day outcome measures including intraoperative technical success, major morbidity, mortality, and graft patency were assessed and compared. At two-year follow-up, estimated outcomes of survival, primary patency, primary assisted patency, secondary patency, freedom from reintervention, and amputation-free survival were analyzed using Kaplan-Meier curves and compared between groups using the log-rank test. In the study period 119 CLTI patients had an infrainguinal bypass with Omniflow® II biosynthetic graft. Seventy-seven patients (64.7%) underwent bypass as "de novo" treatment (group de novo), whilst in the remaining 42 patients (35.3%) the procedure was performed as redo surgery due to occlusion and/or infection of a previous bypass graft (group redo). Two groups were homogeneous in terms of demographic, clinical, and morphological data. In group redo explantation of an infected prosthetic graft was needed in 4 cases (9.5%). Intraoperative technical success was achieved in all cases in both groups. At 30 days, the overall patency rate did not differ between the two groups (69/77, 89.6%, group de novo vs. 35/42, 83.3%, group redo; P=0.24), whilst in group redo limb loss was higher with a statistically significant different 30-day major amputation rate between the two groups (11.9% group redo vs. 1.3% group de novo; P<0.001). Overall median duration of follow-up was eight months (IQR 6-13). At two-year follow-up there were no differences between the two groups in terms of survival (67.7% group de novo vs. 55.8% group redo, P=0.53), primary patency (34.4% group de novo vs. 26.8% group redo, P=0.25), primary assisted patency (43.6% group de novo vs. 28.8% group redo, P=0.12), freedom from reintervention (64.1% group de novo vs. 68.8% group redo, P=0.98), and amputation-free survival (67.8% group de novo vs. 60% group redo, P=0.12). Secondary patency was significantly higher in group de novo (53.7% vs. 32.3%, P=0.05). During the follow-up, the overall rates of graft infection and aneurysmal degeneration were 3.4%, and 0.8%, respectively. Nevertheless, poorer early outcomes in terms of limb salvage, Omniflow® II biosynthetic graft offers acceptable ywo-year outcomes in redo surgery in CLTI patients with no available autologous vein material. Further studies with larger population sizes are needed to validate these outcomes.

Machine Perfusion and Bioengineering Strategies in Transplantation-Beyond the Emerging Concepts.

Solid organ transplantation has progressed rapidly over the decades from the first experimental procedures to its role in the modern era as an established treatment for end-stage organ disease. Solid organ transplantation including liver, kidney, pancreas, heart, and lung transplantation, is the definitive option for many patients, but despite the advances that have been made, there are still significant challenges in meeting the demand for viable donor grafts. Furthermore, post-operatively, the recipient faces several hurdles, including poor early outcomes like primary graft dysfunction and acute and chronic forms of graft rejection. In an effort to address these issues, innovations in organ engineering and treatment have been developed. This review covers efforts made to expand the donor pool including bioengineering techniques and the use of ex vivo graft perfusion. It also covers modifications and treatments that have been trialed, in addition to research efforts in both abdominal organs and thoracic organs. Overall, this article discusses recent innovations in machine perfusion and organ bioengineering with the aim of improving and increasing the quality of donor organs.

When is the Ideal Time to Calculate the Vasoactive Inotropic Score as a Predictor of Mortality and Morbidity in Cardiac Surgery? A Retrospective Study.

The aim of this study was to evaluate the prediction of vasoactive inotropic score (VIS) on early mortality and morbidity after coronary artery bypass grafting (CABG) and to determine the ideal time for score calculation. The study included patients who underwent isolated on-pump CABG surgery between November 2021 and November 2022. Pre, intra, and postoperative data were obtained by retrospective chart review. The final VIS value in the operating room (VISintra) and the highest VIS value in the first 24 hours in the intensive care unit (VISmax) were calculated. The patients were divided into two groups; Group 1 who developed early postoperative morbidity and mortality and Group 2 who did not. And the data were analyzed by groups. A total of 221 patients with a mean age of 63.49 ± 9.96 years were evaluated and 73 (33%) were in Group 1. The cut-off value for VISintra was determined to be 6.20, VISmax was 6,05. VISintra and VISmax values were significantly higher in the poor outcome group. Multivariate analysis showed that only VISmax value was an independent variable on mortality-morbidity. Our results imply that the vasoactive inotropic score is an easy and inexpensive score to calculate and can be used as a specific scoring system to predict poor early outcomes in CABG patients. According to statistical analyses, the most predictive time among VIS measurements was VISmax, the highest value calculated in the ICU in the first 24 hours postoperatively.

Value of Ultrasound Diagnostics in Predicting Ischemic Stroke Outcomes after Different Reperfusion Therapies

Acute ischemic stroke (AIS) is associated with high mortality, disability and economic expenses. Despite significant progress in the treatment of AIS using endovascular methods, it is not always possible to obtain good results. In the current literature, a small number of studies are devoted to predicting outcomes in patients with AIS who received various types of treatment.This prospective cohort study included 460 patients who underwent thrombolytic therapy, thromboextraction, combination of thromboextraction with stenting or thrombolytic therapy.The relationship between clinical and functional results at the early stages after intervention was assessed with potential predictors, among which the ultrasonic characteristics of extra- and intracranial arteries were analyzed.Complete or partial reperfusion was obtained in 61,7 % of the examined patients. A higher efficiency of endovascular methods compared to thrombolytic therapy was noted (99,5 % vs 33,5 % respectively). The baseline NIHSS and Rankin scores did not show a high predictive valuey for early outcomes, that caused the necessary for searching instrumental predictors. Patients with significant stenosis of the internal carotid artery or vertebral artery had significantly worse clinical and functional outcomes, including the mRS scale. The proportion of poor early outcomes in patients with significant stenosis was significantly lower in the endovascular treatment groups compared to the thrombolytic therapy group. Multiple regression analysis showed that the outcome of AIS is influenced by the level of cerebral arterial involvement as well as lesion size with a threshold value of more than 2 cm.

Comparison of VEGF-A levels in women with threatened abortion, early pregnancy loss and uncomplicated healthy pregnancies

IntroductionTo estimate the possible role of VEGF-A in predicting poor early pregnancy outcomes including threatened abortion and early pregnancy loss. MethodsWe conducted a prospective case-control study with three groups of pregnant women diagnosed with threatened abortion, early pregnancy loss, and uncomplicated healthy pregnancies between 01 March 2023 and 15 March 2023. Maternal serum VEGF-A concentration was measured using the Sandwich-ELISA method in accordance to the commercial kit's instructions. There were 30 patients in each 3 group and the gestational age of the patients was between 6 and 14 weeks. The Kruskal-Wallis test was performed for comparing the median values between the groups. Mann-Whitney U test was conducted for pairwise comparisons. ResultsVEGF-A levels were compared between 3 groups and a statistically significant difference was found (p = 0.007). There was a moderately significant correlation between VEGF-A levels and poor early pregnancy outcomes. For poor early pregnancy outcomes, the area under the curve (AUC) was 0.75 (95% CI: 0.64–0.85). The best balance of sensitivity/specificity in ROC curves was 0.60 (63.3% sensitivity, 74.3% specificity). DiscussionIn conclusion, this study pointed out the increased VEGF concentrations in pregnant women with threatened miscarriage and early pregnancy loss.VEGF-A may be a potential biomarker for the indication of poor early pregnancy outcomes.

Validation of the National Institutes of Health Stroke Scale in Intracerebral Hemorrhage

Background We sought to determine if the National Institutes of Health Stroke Scale (NIHSS) has a greater discriminative power than Glasgow coma scale (GCS) to identify patients at risk of poor early functional outcomes and large hematoma volumes. Methods We prospectively collected clinical assessments, imaging, and outcome data in consecutive patients with intracerebral hemorrhage, and determined the ability of GCS and NIHSS to predict poor functional outcome (modified Rankin scale 3–6) and hematoma volume &gt;30 cm 3 using receiver operating characteristics analysis, C‐statistics, and the DeLong test. Results We studied 672 patients with intracerebral hemorrhage (mean age 62±14 years; 56% men; median intracerebral hemorrhage score=1, interquartile range (IQR) 0–2; median intracerebral hemorrhage volume 7 cm 3 , IQR 2–19) with median NIHSS of 8 (IQR 3–18) and GCS 15 (IQR 7–15). NIHSS correlated strongly to GCS (r=−0.773; P &lt;0.001). Admission NIHSS (C‐statistic: 0.91; 95% CI, 0.89–0.93) predicted better than GCS (0.78; 95% CI, 0.75–0.81) discharge poor functional outcome (DeLong test P &lt;0.001). NIHSS (0.82; 95% CI, 0.78–0.86) also discriminated better than GCS (0.78; 95% CI, 0.73–0.83) patients with large hematoma volume (DeLong test P =0.029). Conclusion The NIHSS has a greater discriminative power than GCS to identify patients at risk of poor early functional outcomes and large hematoma volumes.

Patients with poor early clinical outcomes after anatomic total shoulder arthroplasty have sustained poor performance at 2years from surgery.

We sought to define the risk of persistent shoulder dysfunction after anatomic total shoulder arthroplasty (aTSA) beyond the early postoperative period and identify risk factors for persistent poor performance. We retrospectively identified 144 primary aTSAs performed for primary osteoarthritis with early poor performance and 2-year minimum follow-up. Early poor performance was defined as a postoperative ASES score below the 20th percentile at 3- or 6-months (62 and 72 points, respectively). Persistent poor performance at 2years was defined as failing to achieve the patient acceptable symptomatic state (PASS) [ASES = 81.7 points]. At 2-year follow-up, 51% (n = 74) of patients with early poor performance at either 3- or 6-month follow-up had persistent poor performance. There was no difference in the rate of persistent poor performance if patients were poor performers at the 3-, 6-month follow-up, or both (50% vs. 49% vs. 56%, P = .795). Of aTSAs achieving the PASS at 2-year follow-up, a greater proportion exceeded the minimal clinically important differences (MCID) [Forward elevation, external rotation, and all outcome scores] and substantial clinical benefit (SCB) [external rotation and all outcome scores] compared to persistent poor performers. However, over half of persistent poor performers still exceeded the MCID for all outcome measures (56-85%). Independent predictors of persistent poor performance were hypertension (2.61 [1.01-6.72], P = .044) and diabetes (5.14 [1.00-26.4], P = .039). Over half of aTSAs with an ASES score < 20th percentile at early follow-up had continued poor shoulder function at 2-years postoperatively. Persistent poor performance was best projected by preoperative hypertension and diabetes. Level III; Retrospective Cohort Comparison using Large Database; Treatment Study.

Do patients with poor early clinical outcomes after reverse total shoulder arthroplasty ultimately improve?

Although most patients undergoing reverse total shoulder arthroplasty (rTSA) have substantial improvement in pain and function at early follow-up, improvements in pain and range of motion progress more slowly during postoperative rehabilitation in a subset of patients. The purpose of this study was to define a patient's risk of persistent shoulder dysfunction beyond the early postoperative period and identify risk factors for persistent poor performance. We retrospectively reviewed 292 primary rTSAs with early poor performance and a preoperative diagnosis of osteoarthritis, cuff tear arthropathy, or rotator cuff tear from a multicenter database. Early poor performance was defined as a postoperative American Shoulder and Elbow Surgeons (ASES) score below the 20th percentile at 3 months (58 points) or 6 months (65 points) postoperatively. Persistent poor performance at 2 years was defined as failure to achieve the patient acceptable symptomatic state for rTSA (77.3 points for the ASES score). The primary outcome was the rate of persistent poor performance. Secondarily, we compared the clinical outcomes of persistent poor performers vs. shoulders that improved at 2-year follow-up and assessed risk factors for persistent poor performance. At 2-year follow-up, 61% of patients (n = 178) with poor performance at either 3- or 6-month follow-up had persistent poor performance. The rate increased to 85% if poor performance occurred at both 3- and 6-month follow-up. The minimal clinically important difference and substantial clinical benefit for range of motion and outcome scores were exceeded by early poor performers at rates of 83%-92% and 60%-77%, respectively, at 2-year follow-up. On multivariate logistic regression analysis, independent predictors of persistent poor performance after rTSA were lack of hypertension (odds ratio [OR], 0.27; 95% confidence interval [CI], 0.13-0.57; P<.001), heart disease (OR, 2.89; 95% CI, 1.24-6.77; P=.011), uncemented humeral fixation (OR, 0.11; 95% CI, 0.01-1.18; P=.037), previous shoulder surgery (OR, 2.14; 95% CI, 1.06-4.30; P=.031), lower preoperative ASES score (OR, 0.92; 95% CI, 0.87-0.97; P=.002), and lower preoperative subjective rating of pain at its worst (OR, 0.73; 95% CI, 0.54-0.99; P=.038). Despite the fact that 85% of rTSA patients with an ASES score below the 20th percentile at early follow-up exceeded the minimal clinically important difference for improvement in the ASES score at 2-year clinical follow-up, 61% still had persistent poor performance, with failure to achieve the patient acceptable symptomatic state for the ASES score. Persistent poor performance after rTSA was best predicted by a history of shoulder surgery and a poorer preoperative ASES score. These findings can aid surgeons when counseling patients both preoperatively and postoperatively. In the setting of early poor performance, the risk of persistent poor performance must be balanced against the potential outcomes of revision surgery when considering early surgical intervention.

Re-revision Knee Arthroplasty in a Tertiary Center: Infection and Multiple Previous Surgeries Were Associated With Poor Early Clinical and Functional Outcomes

BackgroundThe incidence of re-revision knee arthroplasty (re-revision KA) is increasing and associated with high complication and failure rates. The aim of this study was to investigate re-revision rates, complications, and patient-reported outcomes following re-revision KA and factors associated with poor outcome. MethodsThis was a retrospective cohort study of 206 patients (250 knees) undergoing re-revision KA at a major revision center from 2015 to 2018. The mean follow-up was 26 months (range, 0 to 61) and mean age at re-revision KA was 69 years (range, 31 to 91 years). The main indications for surgery were prosthetic joint infection (PJI) (n = 171/250, 68.4%) and aseptic loosening (n = 25/250, 10.0%). We compared re-revision rates, joint function, and complications for aseptic and infective indications. Logistic regressions were performed to identify risk factors for further reoperation. ResultsThe estimated re-revision rates at 2 years were 28.7% (95% confidence interval [CI]: 22.7-35.9) and at 4 years were 42.0% (95% CI: 32.8-52.6). Mean Oxford Knee Score was 26 points (range, 1 to 48). Mean EuroQoL-5D-5L utility was 0.539 (range, -0.511 to 1.000). Multivariable analyses demonstrated that PJI (Odds Ratio [OR] 2.39, 95% CI 1.06-5.40, P = .036), greater number of previous surgeries (OR 1.18, 95% CI 1.04-1.33, P = .008), and higher Elixhauser score (OR 1.06, 95% CI 1.01-1.13, P = .045) were independently associated to further surgery. ConclusionRe-revision KA carried a high risk of early failure. Multiple revised joints and patients with more comorbidities had worse function. Patients undergoing re-revision KA for PJI should be counseled to expect higher failure rates and complications than patients who have aseptic indications.

Clinical Presentation of Myocarditis in the Pediatric Age Group and Predictors of Poor Early and Late Outcomes: Academic Hospital Experience.

Myocarditis is a leading cause of morbidity and mortality in the pediatric age group and contributes to a wide range of complications, including dilated cardiomyopathy, congestive heart failure, and even death, so early identification and comprehensive management are essential for a favorable outcome. Summarize the presenting clinical signs and symptoms of pediatric patients with a diagnosis of myocarditis and a poor outcome and correlate the clinical presentation and laboratory and radiographic findings to identify possible predictors of a poor outcome. This retrospective cohort study included all patients who were diagnosed with myocarditis and followed up at King Abdulaziz University Hospital, Jeddah, Saudi Arabia over the 13 years between January 01, 2007, and December 31, 2019. Information on patient demographics, clinical presentation, and non-invasive investigations was obtained. Poor outcomes were defined as death or evidence of left ventricular dysfunction on echocardiography which was evaluated at two points in time as an early outcome and a late outcome. Seventeen patients (male 52.9%, female 47.1%) with a median age of 4 ± 4.31 years are included. The most frequent initial complaints were exercise or feeding intolerance, respiratory symptoms, and shortness of breath. On the other hand, hepatomegaly and respiratory distress were the most common clinical signs. All the patients were admitted to the pediatric intensive care unit but only 41% required mechanical ventilation. The presence of a murmur at presentation was significantly correlated with a poor early outcome. Ischemic changes on the electrocardiogram and moderate left ventricular dysfunction on the echocardiogram were significantly correlated with a poor late outcome. Diagnosis of myocarditis can be established by a combination of clinical presentation and investigative tools. A murmur, ischemic changes on the electrocardiogram, and left ventricular dysfunction are important predictors of myocarditis in children.

The Added Value of Intraventricular Hemorrhage on the Radiomics Analysis for the Prediction of Hematoma Expansion of Spontaneous Intracerebral Hemorrhage.

Among patients undergoing head computed tomography (CT) scans within 3 h of spontaneous intracerebral hemorrhage (sICH), 28% to 38% have hematoma expansion (HE) on follow-up CT. This study aimed to predict HE using radiomics analysis and investigate the impact of intraventricular hemorrhage (IVH) compared with the conventional approach based on intraparenchymal hemorrhage (IPH) alone. This retrospective study enrolled 127 patients with baseline and follow-up non-contrast CT (NCCT) within 4~72 h of sICH. IPH and IVH were outlined separately for performing radiomics analysis. HE was defined as an absolute hematoma growth &gt; 6 mL or percentage growth &gt; 33% of either IPH (HEP) or a combination of IPH and IVH (HEP+V) at follow-up. Radiomic features were extracted using PyRadiomics, and then the support vector machine (SVM) was used to build the classification model. For each case, a radiomics score was generated to indicate the probability of HE. There were 57 (44.9%) HEP and 70 (55.1%) non-HEP based on IPH alone, and 58 (45.7%) HEP+V and 69 (54.3%) non-HEP+V based on IPH + IVH. The majority (&gt;94%) of HE patients had poor early outcomes (death or modified Rankin Scale &gt; 3 at discharge). The radiomics model built using baseline IPH to predict HEP (RMP) showed 76.4% accuracy and 0.73 area under the ROC curve (AUC). The other model using IPH + IVH to predict HEP+V (RMP+V) had higher accuracy (81.9%) with AUC = 0.80, and this model could predict poor outcomes. The sensitivity/specificity of RMP and RMP+V for HE prediction were 71.9%/80.0% and 79.3%/84.1%, respectively. The proposed radiomics approach with additional IVH information can improve the accuracy in prediction of HE, which is associated with poor clinical outcomes. A reliable radiomics model may provide a robust tool to help manage ICH patients and to enroll high-risk ICH cases into anti-expansion or neuroprotection drug trials.

Preterm Delivery: Associated Risk Factors And Neonatal Outcomes in Duhok Hospital for Obstetrics And Gynecology

Objectives: To identify the risk factors and evaluate the early neonatal outcomes of premature infants in Duhok Hospital for Obstetrics and Gynecology, a tertiary center in Kurdistan Region - Iraq. Methods: This cross sectional study was carried out from September 1/2021 to December 31/2021. Four hundred participants were recruited, 200 were preterm and 200 were term. The participants were examined and followed till delivery. Multivariable logistic regression analysis was used to identify the risk factors for preterm delivery. Results: The risks factors for preterm delivery were maternal age ≥ 35 years (AOR 3.32; 95 % CI 1.12-9.86), nulliparity (AOR 2.14; 95 % CI 1.25-3.67), history of preterm birth (AOR 6.51; 95 % CI 1.99-21.28,), no ANC (AOR 3.01; 95 % CI 1.32-6.87), &lt; 4 ANC visits (AOR 1.92; 95 % CI 1.12-3.30), PROM (AOR 4.71; 95 % CI 2.71-8.16), antepartum hemorrhage (AOR 9.25; 95 % CI 1.81-47.39), hypertensive disorders in pregnancy (AOR 2.30; 95 % CI 1.12-4.71) and anemia (AOR 3.51; 95 % CI 1.86-6.63). Preterm delivery is linked to poor early neonatal outcomes. Conclusions: Early identification of women at risk for preterm delivery by health care providers is essential to prevent preterm delivery

Long-term outcomes of primary aortic valve repair in children with congenital aortic stenosis - 15-year experience at a single center.

BackgroundStudies on the long-term outcomes of children with congenital aortic stenosis who underwent primary aortic repair are limited. We reviewed the long-term outcomes of children who underwent aortic valve (AoV) repair at our center.MethodsAll children (n = 75) who underwent AoV repair between 2006 and 2020 were reviewed. The Kaplan-Meier curve was used to demonstrate the survival estimates. The Cox proportional hazard model and competing risk regression model were used to identify risk factors for death, reintervention, adverse events, and replacement.ResultsThe median age at surgery was 1.8 (IQR, 0.2–7.7) years, and the median weight at surgery was 10.0 (IQR, 5.0–24.0) kg. Early mortality and late mortality were 5.3% (4/75) and 5.6% (4/71), respectively. Risk factors for overall mortality were concomitant mitral stenosis (P = 0.01, HR: 9.8, 95% CI: 1.8–53.9), low AoV annulus Z-score (P = 0.01, HR: 0.6, 95% CI: 0.4–0.9), and prolonged cardiopulmonary bypass time (P < 0.01, HR: 9.5, 95% CI: 1.7–52.1). Freedom from reintervention was 72.9 ± 0.10% (95% CI: 56.3–94.4%) at 10 years. Risk factors for occurrence of adverse event on multivariable analysis included preoperative intubation (P = 0.016, HR: 1.004, 95% CI: 1.001–1.007) and a low AoV annulus Z-score (P = 0.019, HR: 0.714, 95% CI: 0.540–0.945). Tricuspid AoV morphology was associated with a suboptimal postoperative outcome (P = 0.03).ConclusionAortic valve repair remains a safe and durable solution for children with congenital aortic stenosis. Concomitant mitral stenosis and aortic valve anatomy, including tricuspid valve morphology and smaller annulus size, are associated with poor early and long-term outcomes.

Visceral-to-subcutaneous fat ratio exhibits strongest association with early post-operative outcomes in patients undergoing surgery for advanced rectal cancer

AimDespite their promise as prognostic factors in colorectal cancer, anthropometric data are frequently contradictory or difficult to interpret, with single body-composition parameters often investigated in isolation or heterogeneous clinical cohorts used in analyses. We sought to assess a spectrum of body-composition parameters in a highly selected cohort with locally advanced rectal cancer in a bid to determine those with strongest prognostic potential in this specific setting.Materials/methodsBetween 2014 and 2020, 78 individuals received neoadjuvant chemotherapy, or chemoradiotherapy, followed by radical surgery in the treatment of locally advanced rectal adenocarcinoma at Oxford University Hospitals Trust. Demographic, treatment-related, perioperative, and short-term outcomes data were assessed. Body-composition parameters included BMI, and those derived from pre-operative computed-tomography imaging: skeletal mass index (SMI), visceral fat area (VFA), subcutaneous fat area (SFA), perinephric fat area (PFA) visceral-to-subcutaneous fat ratio (V/S), sarcopenia, and sarcopenic obesity (SO).ResultsPre-operative body-composition parameters exhibited particularly strong correlation with post-operative outcomes, with VFA (p = 0.002), V/S (p = 0.019), SO (p = 0.012), and PFA (p = 0.0016) all associated with an increased length of hospital stay. Univariate and multivariate analyses demonstrated V/S to be the sole independent body-composition risk factor to be associated with an increased risk of developing Clavien–Dindo complications ≥ 2 (p = 0.033) as well as an increased length of stay (p = 0.005).ConclusionAmong patients with locally advanced rectal cancer, high visceral-to-subcutaneous fat ratio is the body-composition parameter most strongly associated with poor early post-operative outcomes. This should be considered in patient selection and prehabilitation protocols.What does this paper add to the literature?Our study demonstrates that among body composition parameters, high visceral-to-subcutaneous fat ratio is strongly associated with increased risk of post-operative complications and increased length of stay in patients undergoing surgery for advanced rectal cancer.

Effect of Cerebral Small Vessel Disease Burden on Outcomes in Patients With Acute Ischemic Stroke Receiving Endovascular Treatment.

BackgroundCerebral small vessel disease (SVD) is common in the aging population. The study aimed to evaluate the effect of SVD on functional outcomes in patients with acute ischemic stroke (AIS) receiving endovascular treatment (EVT).MethodsFrom a prospective registry, we selected patients with AIS receiving EVT. SVD features, including white matter hyperintensities (WMH), lacunes and brain atrophy, were assessed on MRI and a validated SVD score was calculated to reflect the total SVD burden.ResultsAmong 137 patients included, 106 had none-mild SVD burden and 31 had moderate-severe SVD burden. The moderate-severe SVD burden group showed a significantly higher modified Rankin Scale score at 90 d (median, 4 versus 1 points, adjusted common odds ratio 0.32 [95% CI, 0.14–0.69], P < 0.01) and a significantly smaller improvement of NIHSS at 24 h (median, –3 versus –3 points, adjusted β coefficient 4.02 [95% CI, 0.57–7.48], P = 0.02) and 7 days (median, –4 versus –6 points, adjusted β coefficient 4.71 [95% CI, 1.06–8.36], P = 0.01) than the none-mild group. There was no significant difference in successful recanalization, death within 90 days, symptomatic intracranial hemorrhage within 24 h between two groups (all P > 0.05). Additionally, for each single SVD feature, brain atrophy and WMH, but not lacunes, were associated with the functional outcome.ConclusionModerate-severe SVD burden was associated with poor early and late functional outcomes in patients with AIS receiving EVT. Our results suggest that SVD score may act as a good predictor of outcomes in these patients.
