Machine learning algorithm for predicting seizure control after temporal lobe resection using peri-ictal electroencephalography

Brain resection is curative for a subset of patients with drug resistant epilepsy but up to half will fail to achieve sustained seizure freedom in the long term. There is a critical need for accurate prediction tools to identify patients likely to have recurrent postoperative seizures. Results from preclinical models and intracranial EEG in humans suggest that the window of time immediately before and after a seizure (“peri-ictal”) represents a unique brain state with implications for clinical outcome prediction. Using a dataset of 294 patients who underwent temporal lobe resection for seizures, we show that machine learning classifiers can make accurate predictions of postoperative seizure outcome using 5 min of peri-ictal scalp EEG data that is part of universal presurgical evaluation (AUC 0.98, out-of-group testing accuracy > 90%). This is the first approach to seizure outcome prediction that employs a routine non-invasive preoperative study (scalp EEG) with accuracy range likely to translate into a clinical tool. Decision curve analysis (DCA) shows that compared to the prevalent clinical-variable based nomogram, use of the EEG-augmented approach could decrease the rate of unsuccessful brain resections by 20%.

Adverse Events in Targeted Therapy for Unresectable Hepatocellular Carcinoma Predict Clinical Outcomes.

To assess the impact of adverse event (AE) severity, caused by targeted therapy, on overall survival (OS) and progression-free survival (PFS) in patients with unresectable hepatocellular carcinoma (HCC), a total of 183 patients with HCC treated with atezolizumab plus bevacizumab (40), lenvatinib (57), sorafenib (79), cabozantinib (3), ramucirumab (3), and regorafenib (1) were included in this study. Age-, AFP-, and ALBI score-adjusted hazard ratios (HRs) of AE grades 1 to 3 versus grade 0 for OS and PFS were calculated using Cox proportional hazards models. The linear trend of the HRs was assessed by calculating the p values for this trend. The most common AEs were appetite loss (AE grade 0/1/2/3 = 97/23/55/12), general fatigue (102/31/44/6), hypertension (120/6/40/17), hand-foot syndrome (HFS) (135/21/24/3), proteinuria (140/13/16/14), and hypothyroidism (148/12/23/0). The adjusted HRs for OS of these AEs were 0.532-1.450-2.361 (p for trend 0.037), 1.057-1.691-3.364 (p for trend 0.004), 1.176-0.686-0.281 (p for trend 0.002), 0.639-0.759-1.820 (p for trend 0.462), 1.030-0.959-0.147 (p for trend 0.011), and 0.697-0.609 (p for trend 0.119), respectively. Those for PFS of the corresponding AEs were 0.592-1.073-2.811 (p for trend 0.255), 1.161-1.282-4.324 (p for trend 0.03), 0.965-0.781-0.655 (p for trend 0.095), 0.737-0.623-2.147 (p for trend 0.153), 1.061-0.832-0.800 (p for trend 0.391), and 1.412-0.560 (p for trend 0.081), respectively. Appetite loss and general fatigue negatively affected clinical outcomes, whereas hypertension, HFS, proteinuria, and hypothyroidism had positive effects.

Predictors of Clinical Outcomes and Quality of Life After Sternoclavicular Joint Reconstruction With Hamstring Tendon Autograft.

Anterior instability of the sternoclavicular joint (SCJ) is a rare but potentially devastating pathological condition, particularly when it occurs in young or active patients. SCJ reconstruction using hamstring tendon autograft is a commonly used treatment option, yet to date results are limited to small case series. Studies on baseline, preoperative factors and their association with postoperative outcome are limited. To assess the midterm clinical outcomes and survivorship after SCJ reconstruction using hamstring tendon autograft in patients experiencing anterior SCJ instability and to determine whether baseline patient or causative factors are associated with postoperative outcomes or patient satisfaction. Case series; Level of evidence, 4. Patients who underwent SCJ reconstruction with a hamstring tendon autograft for anterior SCJ instability between October 2005 and October 2020 were included in this retrospective single-center study. At a minimum of 2 years postoperatively, clinical outcomes were collected, including the following patient-reported outcomes (PROs): the 12-Item Short Form Survey (SF-12) score; American Shoulder and Elbow Surgeons (ASES) score; Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score; Single Assessment Numeric Evaluation (SANE) score; and visual analog scale (VAS) pain score. Subjective postoperative satisfaction with the procedure was quantified on a scale from 0 (very unsatisfied) to 10 (very satisfied). The predictive role of patient factors, including age, sex, and injury in dominant arm, on postoperative PROs and satisfaction at short-term follow-up was evaluated using multiple linear regression. A total of 49 patients (mean age, 29.6 ± 16.2 years; range 13.8-67.1 years; 27 females) were included in the final analysis. At a mean follow-up of 3.9 ± 2.1 years, all PROs had significantly improved, including the mean SF-12 Physical Component Summary score (40.4 ± 6.8 to 52.6 ± 6.9; P < .001), ASES score (54.9 ± 20.4 to 91.0 ± 11.3; P < .001), QuickDASH score (41.2 ± 18.5 to 10.2 ± 9.1; P < .001); SANE score (50.2 ± 21.1 to 88.3 ± 8.8; P < .001), VAS pain score (4.4 ± 2.6 to 0.8 ± 1.4; P < .001), and VAS pain score at its worst (7.4 ± 2.5 to 3.3 ± 2.6; P < .001). The median postoperative satisfaction score was 9 (range, 1-10). Revision-free survivorship was 95.9%. Male patients had a significantly lower VAS pain score at its worst compared with female patients (2.6 ± 2.6 vs 4.1 ± 2.4; P = .045); higher age was significantly correlated with a worse QuickDASH score (correlation coefficient, 0.314; P = .036). Overhead athletes had a significantly lower propensity to return to sport compared with nonoverhead athletes (P = .043), with only 45% of the overhead athletes returning to a level similar to their preinjury level, whereas 81% of the nonoverhead athletes were able to do so. The significant improvements in clinical and sport-specific outcomes and high patient satisfaction after SCJ reconstruction with a hamstring tendon autograft demonstrate the success of this procedure in treating anterior SCJ instability. Male sex and younger patient age are associated with superior outcomes, while overhead athletes have to be counseled about difficulties of returning to preinjury level of sport postoperatively.

Predictors of long-term clinical outcomes after TIPS: An ALTA group study.

While transjugular intrahepatic portosystemic shunt (TIPS) is traditionally considered a bridge to liver transplant (LT), some patients achieve long-term transplant-free survival (TFS) with TIPS alone. Prognosis and need for LT should not only be assessed at time of procedure, but also re-evaluated in patients with favorable early outcomes. Adult TIPS recipients in the multicenter Advancing Liver Therapeutic Approaches retrospective cohort study were included (N=1,127 patients; 2,040 person-years follow-up). Adjusted competing risk regressions were used to assess factors associated with long-term post-TIPS clinical outcomes at time of procedure and at 6 months post-TIPS. MELD-Na at TIPS was significantly associated with post-TIPS mortality (sHR of death 1.1 [p=0.42], 1.3 [p=0.04], and 1.7 [p<0.01] for MELD-Na 15-19, 20-24, and ≥25 relative to MELD-Na <15, respectively). MELD 3.0 was also associated with post-TIPS outcomes. Among the 694 (62%) patients who achieved early (6mo) post-TIPS TFS, rates of long-term TFS were 88% at 1-year and 57% at 3-years post-TIPS. Additionally, a within-individual increase in MELD-Na score of >3 points from TIPS to 6 months post-TIPS was significantly associated with long-term mortality, regardless of initial MELD-Na score (sHR of death 1.8, p<0.01). For patients with long-term post-TIPS TFS, rates of complications of the TIPS or portal hypertension were low. Among patients with early post-TIPS TFS, prognosis and need for LT should be reassessed, informed by post-procedure changes in MELD-Na and clinical status. For selected patients, "destination TIPS" without LT may offer long-term survival with freedom from portal hypertensive complications.

Role of right ventricular–pulmonary arterial coupling assessed by echocardiography to predict adverse outcomes in patients with acute pulmonary embolism

BackgroundPulmonary embolism (PE) is a lethal type of venous thromboembolic disease. Right ventricular (RV) failure is not an uncommon complication of PE leading to higher adverse outcomes. The tricuspid annular peak systolic excursion/pulmonary artery systolic pressure (TAPSE/PASP) ratio as a surrogate for RV–pulmonary artery coupling has proven to be among the predictor of clinical outcomes in multiple patient groups. We evaluated in this study the role of TAPSE/PASP ratio in predicting adverse clinical outcomes in patients with acute PE.ResultsAmong patients with established diagnosis of acute PE admitted to the coronary care unit, echocardiography was done within 12 h of admission and TAPSE/PASP ratio was calculated. The patients were followed during hospitalization and after discharge for 3 months for development of adverse outcomes including rehospitalization due to heart failure, recurrent PE and mortality. A total of fifty-five consecutive patients were recruited with mean age 58.3 ± 6.9 years and nearly equal male-to-female ratio. The mean ratio of TAPSE/PASP was 0.479 ± 0.206. In-hospital and 3-month follow-up showed that 10.9% needed rehospitalization with heart failure, 14.5% developed recurrent pulmonary embolism, and mortality was 9.1%. TAPSE/PASP ratio was significantly lower among the patients who developed adverse outcomes. TAPSE/PASP ratio was among the independent predictors of rehospitalization with heart failure, recurrent pulmonary embolism but not mortality at 3-month follow-up. TAPSE/PASP ratio predicted rehospitalization with heart failure at a cutoff point ≤ 0.325, with 100% sensitivity and 79.6% specificity, and predicted recurrent pulmonary embolism at a cutoff point ≤ 0.325, with 75% sensitivity and 78.7% specificity.ConclusionTAPSE/PASP ratio is a noninvasive tool that can predict the development of early adverse outcomes in patients with acute PE including rehospitalization with heart failure and recurrent pulmonary embolism.

Magnetic resonance imaging patterns and perfusion changes of posterior reversible encephalopathy syndrome in children with clinical outcome correlation.

Posterior reversible encephalopathy syndrome (PRES) in children has a propensity towards atypical features on magnetic resonance (MR) imaging, with limited literature on perfusion changes and clinicoradiological correlation. We aimed to comprehensively study MR imaging patterns of pediatric PRES, including cerebral blood flow variations on arterial spin labeling, and looked for any MR biomarkers of poor clinical outcome. In this retrospective observational study conducted in a tertiary hospital setting, MR records over a 4-year period (May 2019 to May 2023) were systematically searched along with their clinical details. Patients with an age less than 18years and a clinicoradiological constellation consistent with PRES were included. MR scans were analyzed by two neuroradiologists with 8years' and 10years' experience. Association was sought with poor clinical outcome (defined as modified Rankin Scale score at discharge of > 2). A total of 45 patients (29 boys) were included in the study, with a mean age (± standard deviation) of 11.19 (± 4.53) years. On MR imaging, 95.6% of patients (n = 43) showed atypical features and/or atypical areas of involvement. The superior frontal sulcus (n = 18) was the most predominant MR pattern, and cerebellar involvement was not uncommon (n = 15). Unilateral involvement (n = 3), isolated central pattern (n = 1), and spinal cord involvement (PRES-SCI: n = 1) were also encountered. Brainstem involvement (n = 4) showed a characteristic "V-sign" of anterior medullary hyperintensity. Patchy restricted diffusion (46.6%), punctate hemorrhages (37.7%), and leptomeningeal contrast enhancement (36%) were not uncommon. Arterial spin labeling sequence (available in 24 patients) showed increased cerebral blood flow in the involved areas in 79.2% of patients. Univariate analysis showed a significant association of the presence of hemorrhage (P = 0.003), involvement of brainstem (P = 0.007), deep white matter (P = 0.008), and thalamus (P = 0.026) with poor clinical outcome. Multivariate regression analysis found that hemorrhage on MRI (P = 0.011, odds ratio 8) was an independent factor associated with poor clinical outcome. The conventionally described atypical features in PRES are common in children and therefore may no longer be considered exceptions. Raised perfusion on arterial spin labeling sequence was seen in the majority of cases. Hemorrhage on MRI was an independent predictor of poor clinical outcome in pediatric PRES.

SEPT9: From pan-cancer to lung squamous cell carcinoma

BackgroundSEPT9 is a pivotal cytoskeletal GTPase that regulates diverse biological processes encompassing mitosis and cytokinesis. While previous studies have implicated SEPT9 in tumorigenesis and development; comprehensive pan-cancer analyses have not been performed. This study aims to systematically explore its role in cancer screening, prognosis, and treatment, addressing this critical gap.MethodsGene and protein expression data containing clinical information were obtained from public databases for pan-cancer analyses. Additionally, clinical samples from 90 patients with lung squamous cell carcinoma (LUSC) were used to further experimentally validate the clinical significance of SEPT9. In addition, the molecular docking tool was used to analyze the affinities between SEPT9 protein and drugs.ResultsSEPT9 is highly expressed in various cancers, and its aberrant expression correlates with genetic alternations and epigenetic modifications, leading to adverse clinical outcomes. Take LUSC as an example, additional dataset analyses and immunohistochemical experiments further confirm the diagnostic and prognostic values as well as the clinical relevance of the SEPT9 gene and protein. Functional enrichment, single-cell expression, and immune infiltration analyses revealed that SEPT9 promotes malignant tumor progression and modulates the immune microenvironments, enabling patients to benefit from immunotherapy. Moreover, drug sensitivity and molecular docking analyses showed that SEPT9 is associated with the sensitivity and resistance of multiple drugs and has stable binding activity with them, including Vorinostat and OTS-964. To harness its prognostic and therapeutic potential in LUSC, a mitotic spindle-associated prognostic model including SEPT9, HSF1, ARAP3, KIF20B, FAM83D, TUBB8, and several clinical characteristics, was developed. This model not only improves clinical outcome predictions but also reshapes the immune microenvironment, making immunotherapy more effective for LUSC patients.ConclusionThis is the first study to systematically analyze the role of SEPT9 in cancers and innovatively apply the mitotic spindle-associated model to LUSC, fully demonstrating its potential as a valuable biomarker for cancer screening and prognosis, and highlighting its application value in promoting immunotherapy and chemotherapy, particularly for LUSC.

Usefulness of frailty assessment using the revised Japanese version of the Cardiovascular Health Study on the prediction of clinical outcomes in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement.

Frailty assessment is essential for deciding the treatment strategy for patients with aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). Recently, the revised Japanese version of the Cardiovascular Health Study (J-CHS) criteria has been proposed for the frailty assessment; however, it is unclear whether the criteria are useful for the risk stratification in these patients. We investigated the impact of frailty assessment using the revised J-CHS criteria on clinical outcomes in patients with AS undergoing TAVR. We examined 205 consecutive severe AS patients who underwent TAVR at two tertiary hospitals from May 2018 to December 2022. Frailty was defined by the revised J-CHS criteria (score ≥ 3) before TAVR. The primary outcome was major adverse cardiac or cerebrovascular events (MACCE). Among the studied patients, the mean age was 84years and 65% were female. Frailty was present in 51% of patients. During a median follow-up period of 1000 (interquartile range 677-1210) days, MACCE occurred in 22 patients. Frailty was significantly independently associated with higher risks of the MACCE adjusted for confounders related to nutritional status, severity of AS, comorbidities [hazard ratio (HR) 5.09, 95% confidence interval (CI) 1.70-15.23; HR 3.94, 95% CI 1.34-11.55; HR 3.12, 95% CI 1.14-8.53; HR 3.31, 95% CI 1.21-9.02, respectively]. Frailty determined by the revised J-CHS criteria was associated with clinical outcomes, suggesting these criteria would be useful for risk stratification in Japanese patients with AS undergoing TAVR.

Clinical Characteristics and Outcome Predictors in Drug-Resistant Tuberculosis: A Comprehensive Analysis

Background: Drug-resistant tuberculosis (DR-TB) poses significant challenges to public health, with poor outcomes frequently observed in affected patients. This study aims to evaluate the characteristics and factors associated with poor outcomes in patients with drug-resistant pulmonary tuberculosis at Liwa Hospital from January 2018 to May 2023. Methods: A retrospective, cross-sectional single-center analysis was conducted on 408 patients admitted to Liwa Hospital. Among these, 28 patients diagnosed with drug-resistant tuberculosis (DR-TB) were selected for detailed analysis based on their treatment outcomes and clinical data. Inclusion criteria encompassed patients aged 18 years or older with confirmed drug-resistant TB, while patients younger than 18, those with latent tuberculosis, and those with extra-pulmonary tuberculosis were excluded. Results: The majority of patients were between 18-40 years old (60.7%), predominantly male (85.7%), and Asian (96.4%). Comorbidities included diabetes (46.4%) and hypertension (21.4%). Clinical characteristics revealed cough (28.6%) and fever with cough (7.1%) as common symptoms. Primary resistance was observed in 92.9% of cases, with 96.4% being newly diagnosed TB cases. Adverse drug events were minimal, with 7.1% experiencing nausea and vomiting. Radiological findings showed unilateral TB in 53.6% and cavitary TB in 57.1% of cases. Laboratory analysis indicated elevated HbA1c (9.83 ± 3.25), CRP (25.94 ± 5.16 mg/L), and white blood cell count (9.94 ± 4.59 x 10^9 cells/L). Rifampicin resistance was the most prevalent (42.9%), followed by isoniazid resistance (25.0%). Regarding treatment outcomes, age, hypertension, and diabetes mellitus were found to be significantly associated with poor outcomes in patients (p=0.05). Conclusion: The study identified significant associations between treatment outcomes and age, hypertension, and diabetes status, with higher proportions of poor outcomes observed in patients. Comprehensive management strategies targeting these factors are essential to improve outcomes in patients with drug-resistant TB. Further research is warranted to develop tailored interventions for this population.

Outcomes After Extracorporeal Shockwave Therapy for Chronic Noninsertional Achilles Tendinopathy Compared With Chronic Insertional Achilles Tendinopathy: A Retrospective Review.

Extracorporeal shockwave therapy (ESWT) is a noninvasive treatment modality that is used in the treatment of chronic Achilles tendinopathy (AT). To (1) retrospectively assess outcomes after ESWT for both noninsertional AT (NAT) and insertional AT (IAT) at >1-year follow-up and (2) identify potential predictors of outcomes. Cohort study; Level of evidence, 3. Chart review was conducted to identify patients who underwent ESWT for AT with a minimum of 1-year follow-up. Data collected and assessed included patient demographic characteristics, pathological characteristics including the location of AT (NAT or IAT), presence of a Haglund deformity, and severity of tendon degeneration on magnetic resonance imaging (MRI), in addition to treatment characteristics including number of sessions and intensity of ESWT. The Victorian Institute of Sports Assessment-Achilles (VISA-A) and visual analog scale (VAS) pain scores were obtained before ESWT, 6 months after ESWT, and at final follow-up. Failures were also recorded, which were defined as no improvement in VISA-A or VAS scores or need for surgical intervention. Linear regression was performed to identify potential predictors of inferior subjective clinical outcomes and failures. Survival analysis was conducted using Kaplan-Meier curves. The study included 52 patients with IAT and 34 patients with NAT. The mean follow-up in the NAT cohort was 22.3 ± 10.2 months and the mean follow-up in the IAT cohort was 26.8 ± 15.8 months. Improvements in VISA-A and VAS scores were observed in the NAT cohort at 6-month follow-up and at final follow-up (P < .05). Improvements in VISA-A and VAS scores were recorded in the IAT cohort at 6-month follow-up, which subsequently deteriorated at final follow-up. In the NAT cohort, the failure rate at 6-month follow-up was 11.8%, which increased to 29.4% at final follow-up. In the IAT cohort, the failure rate at 6-month follow-up was 32.7%, which increased to 59.6% at final follow-up. Predictors of inferior subjective clinical outcomes and failures in the NAT cohort included pre-ESWT subjective clinical score, male sex, presence of a cardiovascular risk factor, and more severe MRI grading of tendinopathy. Predictors of inferior subjective clinical outcomes and failures in the IAT cohort included pre-ESWT subjective clinical score and more severe MRI grading of tendinopathy. Superior subjective clinical outcomes together with a lower failure rate were maintained for >1 year in the NAT cohort compared with the IAT cohort, calling into question the long-term benefit of ESWT for patients with IAT.

Effects of thrombus characteristics on clinical outcome and success of recanalization in acute ischemic stroke

Background: Despite current developments in mechanical thrombectomy (MT), successful recanalization cannot be achieved in all patients. One of the factors related to this is the characteristics of the thrombus. In this study, we aimed to evaluate the effects of thrombus length and permeability on procedural success and clinical outcome. Methods: Patients with intracranial ICA, middle cerebral artery M1, or M2 occlusions, who underwent MT between November 2019 and January 2022 were included in the study. Thrombus length, density and permeability were calculated and the relationship between recanalization success and modified Rankin Scores (mRS) at the 3rd month was evaluated. Good clinical outcome was defined as an mRS score of 2 or less. Results: Forty-six of the 79 patients included in the study had a good clinical outcome. Although thrombus length was shorter and permeability was higher in patients with good clinical outcome, statistical significance was not achieved. There was a positive correlation between thrombus density, thrombus length and the number of passes, and a negative correlation between permeability. There was no significant difference in thrombus length, density and permeability between patients with and without successful recanalisation. Thrombus length was found to be a predictor of clinical outcome at 3 months in univariate analysis, whereas only age was found to be an independent predictor in multivariate analysis. Conclusions: In conclusion, despite certain findings not achieving statistical significance, the observed trends offer valuable insights for future research. A comprehensive understanding of thrombus nature could guide personalized stroke treatment strategies in the future.

Peripheral Blood Neutrophil Nadir and Time to Platelet Recovery during Induction Chemotherapy: Predictors of Clinical Outcomes and Markers for Optimizing Induction Treatment Intensity in Acute Lymphoblastic Leukemia.

To study the kinetics of blood count nadir and time to recovery and find its association with clinical outcomes in a cohort of Acute Lymphoblastic Leukemia (ALL). Data from 243 cases treated between January 2018 to December 2020 was retrospectively analysed. Along with baseline data, serial measures of peripheral blood counts, nadir, and time to partial and complete recovery of counts during course of induction chemotherapy were recorded. Post-induction Complete Remission (CR) status, Event-Free Survival (EFS) , and Overall Survival (OS) were recorded as clinical outcomes for analysis. Median age was 15 (range,1-62) years. Immunophenotype was B-ALL in 71% (n=172), and T-ALL in 27% (n=66). Good steroid response (D8) was seen in 89%(n=216), CR in 79% (n=192), and induction mortality in 12% (n=29). Median neutrophil nadir was 0.06(0-0.49) *10⁹/L and median day to nadir was D17. Median time to partial and complete platelet recovery was D18 and D25. Late neutrophil nadir (>D15) was independent predictor of refractory disease post-induction [OR=5.43 (95%CI 1.06-27.75)]. Late partial platelet recovery (>D22) was independent predictor of poorer EFS and OS [HR = 1.63 (95%CI 1.07-2.47)] and [HR = 1.5 (95% CI 1-2.4)] respectively. We found that a longer time to neutrophil nadir independently predicts refractory disease post-induction and late partial platelet recovery is an independent factor for poorer EFS and OS. Thus, Blood count kinetics as independent predictors of induction outcomes can provide a simple, easy-to-use tool for balancing toxicity-efficacy during induction therapy for ALL.

Clinical characteristic, laboratory biomarkers, treatment regimen and psychiatry problems predictors of outcomes of alopecia areata: a prospective study

Background Alopecia areata (AA) has multiple aetiology such as genetic and environmental triggers. Aims To assess the recovery rate of AA and examine the associated psychiatric problems. Additionally, the relationship between clinical, psychiatric, and laboratory biomarkers and alopecia outcomes were investigated, along with potential risk factors that could aid in treating alopecia. Patients and methods A prospective cohort research included 42 AA patients and 45 healthy controls. Group A (active disease), group B (inactive disease), and group C (healthy control) were based on illness outcomes after 3 months of treatment. The Severity of Alopecia Tool (SALT), treatment regimens, laboratory investigation Interleukins 19 and 33 (IL-19 and IL-33), Symptom Checklist 90, and post-traumatic stress disorder Checklist for DSM-5 (PCL-5) were evaluated. Results After 3 months of therapy, the incidence of inactive AA was found to be 57.14%. Being females with family history of dermatitis were highly related with active illness, while smoking and unmarried patients were associated with inactive disease. After 3 months of treatment, active illness had the highest mean IL-33 and IL-19 levels. Conclusion The active disease group exhibited the highest mean IL-33 and IL-19 levels at baseline following three months of treatment. Our patients had 7.1% somatization, 7.1% obsessive-compulsive symptoms, 4.8% depression, 4.8% anxiety, 15.9% anger-hostility, 35.7% phobic-anxiety, 26.2% paranoid ideation, 4.8% psychoticism, and 61.9% post-traumatic stress disorder. AA outcomes were linked to females, a family history of dermatological disorders, smoking, being single, and higher mean IL-33 and IL-19 levels. Psychosis was highly linked with active AA. Only khellin and Ultraviolet A improved AA results.

Association of Admission Hyperglycemia with Clinical Outcomes in Patients with Symptomatic Intracranial Hemorrhage After Endovascular Treatment for Large Vessel Occlusive Stroke.

Symptomatic intracranial hemorrhage (sICH) is a fatal complication after endovascular treatment (EVT) for acute large vessel occlusive (LVO) stroke. The aim of this study was to investigate the association between hyperglycemia and outcomes in patients with postprocedural sICH. Of the 2567 patients with AIS who underwent EVT from two large multicenter randomized trials and two prospective multicenter registry studies, 324 patients occurred sICH with documented admission glucose were included in this study. The primary outcome was functional independence (defined as a modified Rankin Scale score of 0 to 2) at 90 days. Secondary outcomes included mRS score of 0 to 3, 0 to 1, and mRS score at 90 days. Safety outcome was the mortality within 90 days. Admission hyperglycemia was defined as a plasma blood glucose ≥7.8 mmol/L (140 mg/dL) in our analysis. Of 324 eligible participants included in this study, hyperglycemia was observed in 130 (40.1%) patients. The median age was 67 (IQR, 58-75) years, and median blood glucose level was 7.1 (IQR, 6.0-9.3) mmol/L. After adjusting for confounding variables, admission hyperglycemia was associated with decreased odds of functional independence (adjusted odds ratio[OR] 0.34; 95% CI 0.17-0.68; P= 0.003), decreased odds of favorable outcome (adjusted OR 0.31; 95% CI 0.16-0.58; P < 0.001) and increased odds of mortality (adjusted OR 2.56; 95% CI 1.47-4.45; P = 0.001) at 90 days. After 1:1 propensity score matching analysis, the results were consistent with multivariable logistic regression analysis. In patients who suffered sICH after EVT for acute large vessel occlusive stroke, hyperglycemia is a strong predictor of poor clinical outcome and mortality at 90 days.

Long-Term Outcome of Motor Functional Neurological Disorder After Rehabilitation.

Functional neurological disorder (FND) is defined as the presence of neurological symptoms that are inconsistent with a neurological disease. We performed a single-center retrospective study aimed at determining the long-term outcome of FND patients receiving inpatient rehabilitation and the predictors of a good outcome. A multidisciplinary graded exercise program was provided with one or two daily physiotherapy and occupational therapy sessions on 5 days each week, as well as weekly psychological support. Outcome was assessed using the motor part of the Functional Independence Measure scale (FIM; maximum score of 91) at admission, discharge, and follow-up, with the last assessment performed by phone interview. The 30 included patients were aged 43.6±14.7 years (mean±standard deviation), comprised 70% females, and received a mean of 4 weeks of rehabilitation. The admission FIM score (80.2±8.3) was significantly lower than the discharge FIM score (86.9±4.6; p<0.001, Wilcoxon signed-rank test). No notable difference was observed between discharge and follow-up FIM scores (85.5±8.5, p=0.54). The mean follow-up of the 36-month FIM scores at discharge and follow-up was dichotomized as a good outcome in cases where all items were scored ≥6 (functional independence). Binomial logistic regression showed that absence of a comorbid psychiatric disorder (p=0.039, odds ratio=10.7) was a predictive factor for a good outcome at follow-up. Other variables (e.g., sex and age) were not significant predictors of clinical outcome (all p≥0.058). These results suggest inpatient intensive rehabilitation for motor FND is effective and produces favorable long-term results. Further studies with larger groups are warranted so that the management protocols can be standardized.

509. DOES SARCOPENIA AFFECT THE OUTCOME OF PATIENTS WITH ESOPHAGEAL CARCINOMA AFTER ESOPHAGECTOMY?

Abstract Background Sarcopenia is increasingly recognized as an independent predictor of clinical outcomes of cancer patients such as post-operative complications and prolonged hospital stays. Additionally, sarcopenia can also negatively impact overall survival because of reduced ability to tolerate treatments like neoadjuvant therapy and surgery. At particular risk among cancer patients is the esophageal cancer population because of tumor stenosis leading to dysphagia and impossibility of oral feeding in many patients. The purpose of the current study was to investigate the effect of preoperative sarcopenia on postoperative complications in patients undergoing esophagectomy for esophageal cancer. Methods This retrospective study includes all patients who underwent full-robotic abdominothoracic esophageal resection because of esophageal cancer at our institution between 06/2020 and 12/2022. The skeletal muscle index (SMI) was assessed using the preoperative computed tomographic staging scans by measuring the cross-sectional muscle area at the third lumbar vertebral level. Following cut off SMI values were used to define sarcopenia: men: 52,4 cm2/m2, women: 38,5 cm2/m2 according to Prado et al (Lancet Oncol, 2008). Recorded parameters included demographic data, neo-adjuvant treatment, histologic findings, postoperative course and overall- and disease-free survival. Results A total of 113 cases were included in this preliminary analysis. 97 patients (86%) were classified as having sarcopenia. Of these, 38 patients (40%) had a preoperatively or during esophageal resection implemented percutaneous endoscopic jejunostomy (PEJ) tube to ensure enteral nutrition. Despite age, groups were comparable regarding neoadjuvant treatment and histologic findings (mean age sarcopenic patients: 66y vs. 61y non-sarcopenic patients, p = 0.03). There was no difference in the incidence of occurrence of anastomotic leakage, pulmonary complications, need for re-operation, length of (ICU) stay and overall- and disease-free survival between sarcopenic and non-sarcopenic patients. Conclusion Incidence of sarcopenia is very high among esophageal cancer patients. In our study population, however, preoperative sarcopenia failed to predict complications or long-term outcome after esophagectomy for esophageal cancer. 40% of the sarcopenic patients received a PEJ. This relatively high proportion of implemented PEJ could have contributed to the observed comparable outcomes between sarcopenic and non-sarcopenic patients. This observation underlines the importance of prehabilitation and nutritional support for patients with preoperative sarcopenia.

TMS-induced plasticity improving cognitive control in OCD II: Task-based neural predictors of treatment response

ObjectiveRepetitive transcranial magnetic stimulation (rTMS) has the potential to increase the clinical effect of exposure with response prevention (ERP) psychotherapy for obsessive-compulsive disorder (OCD). We investigated the use of task-based functional MRI (tb-fMRI) for predicting clinical outcomes to different rTMS protocols combined with ERP in OCD. Method61 adults with OCD underwent rTMS and ERP and were randomized to different high frequency rTMS conditions: left dorsolateral prefrontal cortex (DLPFC; n=19), left pre-supplementary motor area (preSMA; n=23), and control stimulation at the vertex at low intensity (n=19). The Tower of London task and Stop-Signal Task were used to assess pretreatment activation during planning and inhibitory control, respectively. We adopted a Bayesian region-based approach to test whether clinical improvement can be predicted by tb-fMRI-derived measures of task-related brain activation or functional connectivity between task-relevant regions and the bilateral amygdala. ResultsFor the vertex group, but not the DLPFC/preSMA rTMS conditions, higher activation in several task-relevant regions during planning and response inhibition, and lower error-related activation, corresponded with better short-term clinical improvement. Lower precuneus activation with increased planning taskload correlated with symptom reduction in the DLPFC group. In the preSMA group, higher error-related activation and lower inhibition-related insular-amygdalar connectivity was associated with symptom reduction. ConclusionsPretreatment tb-fMRI-derived measures of activation and connectivity during planning and inhibition-related processes are associated with clinical response for specific rTMS conditions in OCD. Future placebo-controlled trials with larger sample sizes should combine clinical information and neural correlates to improve prediction of clinical outcome.

Establishment and validation of a nomogram model for prediction of clinical outcomes in patients with amanita phalloides poisoning

Amanita phalloides poisoning, renowned for its high mortality rates, is one of the most serious food safety issue in certain regions worldwide. Assessment of prognosis and development of more efficacious therapeutic strategies are critical importance for amanita phalloides poisoning patients. The aim of the study is to establish a nomogram to predict the clinical outcome of amanita phalloides poisoning patients based on the independent risk factor for prognosis. Herein, between January 2013 and September 2023, a cohort of 149 patients diagnosed with amanita phalloides poisoning was enrolled and randomly allocated into training and validation cohorts, comprising 102 and 47 patients, respectively. Multivariate logistic regression analysis was performed to identify the independent risk factors for morality of amanita phalloides poisoning patients in training cohort. Subsequently, a nomogram model was constructed to visually display the risk prediction model. The predictive accuracy of nomogram was verified by the validation cohort. The C index, the area under the receiver operating characteristic curve (AUC), and calibration plots were used to assessed the performance of nomogram. The clinical utility was evaluated by decision curve analysis (DCA). In the present study, the results showed that hepatic encephalopathy (HE), upper gastrointestinal bleeding (UGB), AST, and PT were the independent risk factors associated with the mortality of amantia phalloides poisoning patients. We constructed a new nomogram to evaluate the probability of death induced by amantia phalloides poisoning. The AUC for the prediction accuracy of the nomogram was 0.936 for the training cohort and 0.929 for the validation cohort. The calibration curves showed that the predicted probability matched the actual likelihood. The results of the DCA suggested that the nomogram has a good potential for clinical application. In summary, we developed a new nomogram to assess the probability of mortality for amanita phalloides poisoning patients. This nomogram might facilitate clinicians in making more efficacious treatment strategies for patients with amanita phalloides poisoning.
