Long-term outcomes following posterior fossa decompression in pediatric patients with Chiari malformation type 1, a population-based cohort study

Abstract Objective Posterior fossa decompression for Chiari malformation type I (Chiari 1) is effective and associated with a low risk of complication. However, up to 20% of patients may experience continued deficits or recurring symptoms after surgical intervention. For pediatric patients, there are no established tools to predict outcomes, and the risk factors for unfavorable postoperative outcomes are poorly understood. Hence, our aim was to investigate baseline data and early postoperative predictors of poor outcomes as determined by the Chicago Chiari outcome scale (CCOS). Methods All pediatric patients (< 18 years) receiving a posterior fossa decompression for Chiari 1 between the years of 2005 and 2020 at the study center were eligible for inclusion. Patients with congenital anomalies were excluded. Results Seventy-one pediatric patients with a median age of 9 years were included. Most patients (58%) were females. Chiari 1 was associated with syringomyelia (51%), scoliosis (37%), and hydrocephalus (7%). Perioperative complications occurred in 13 patients (18%) of which two required additional procedures under general anesthesia. On multivariable proportional odds logistic regression, motor deficits (OR: 0.09; CI95%: [0.01–0.62]; p = 0.015), and surgical complications (OR: 0.16; CI95%: [0.41–0.66]; p = 0.011) were significant predictors of worse outcomes. The presence of syringomyelia was identified as a predictor of better outcomes (OR: 4.42 CI95% [1.02–19.35]; p = 0.048). A persistent hydrocephalus during the early postoperative period after posterior fossa decompression was a strong predictor of worse long-term CCOS (OR: 0.026; CI95%: [0.002–0.328]; p = 0.005). Conclusion Results from this study indicate that the existence of motor deficits and syringomyelia prior to surgery, and surgical complications and persistent hydrocephalus despite posterior fossa decompression, were useful predictors of long-term outcome.

Immigrant Generation, Ethnicity, and Early-life Education Outcomes: Evidence from the Born in Bradford Family Cohort Study

Abstract This paper examines the relationship between ethnicity and immigrant generation in relationship to early educational outcomes and their potential determinants. Using Born in Bradford, a large longitudinal birth cohort, and its linked education and health records, we investigated the associations between ethnicity, immigration generations and education measures (Early Years Foundation Stage Profile and National Curriculum Key Stage One). We looked at the children of both first- and second-generation immigrants and compared them with White British non-immigrant children. Logistic regressions were used to examine the explanatory factors of the differences. On the Early Years Foundation Stage Profile, children of first-generation Pakistani immigrants did less well than White British non-immigrant children. This was largely related to language barriers. There were no significant differences between the children of second-generation Pakistani families and children of White British non-immigrant families. In Key Stage One results, there were no differences in reading and maths between children of first-generation Pakistani immigrants and the White British children, however, children of first-generation Pakistani immigrants had better scores in Key Stage One writing. Children of second-generation Pakistani immigrants had better odds of achieving expected standards in most models for reading and writing (but not maths) than the White British children. This might be attributed to better socioeconomic circumstances. Immigrant generation is an independent predictor for early educational outcomes. There are different patterns associated with different immigrant generations. Early life policy interventions to help children of first-generation immigrant with their English language before school could improve these children’s school readiness.

Comparison of functional outcome after intracerebral hemorrhage in patients with or without end stage renal disease on hemodialysis: a propensity-score matched study

Abstract Background End stage renal disease (ESRD) requiring hemodialysis (HD) increases mortality among patients with intracerebral hemorrhage (ICH). The aim of this study is to investigate the clinical characteristics and outcome of ICH patients with ESRD on HD versus propensity-score matched controls. Methods This is a single center retrospective study. Consecutive ICH admissions at the University of California, Irvine Medical Center from January 1, 2018 to July 31, 2022 were analyzed. Results Among 347 ICH admissions that met inclusion criteria, 24 patients (6.92%) had ESRD on HD. Compared to patients without ESRD, patients with ESRD on HD had significantly higher rate of diabetes mellitus (79.2% vs. 36.8%, p < 0.01) and in-hospital mortality (25% vs. 7.43%, p < 0.01). There were no significant differences in demographics, other comorbidities, clinical characteristics, good (mRS score 0–3) or poor (mRS score 4–5) functional outcomes, rate of comfort care and the time to comfort care decision between the 2 groups. After propensity score matching, the ESRD group had a significantly higher in-hospital mortality rate (27.3% vs. 8%, p = 0.012) and a lower rate of obesity (9.1% vs. 34.1%, p = 0.02). Among patients who died during admission, ESRD on HD status did not inadvertently influence end-of-life care decisions. Univariate logistic regression and area under curve analysis showed that ICH score ≥ 3 was a predictor of increased mortality in both ESRD and non-ESRD groups. Conclusions ICH patients with ESRD on HD had significantly higher in-hospital mortality and lower rate of obesity than propensity score matched controls, suggesting a survival benefit from obesity. ICH score ≥ 3 is an independent predictor for poor outcomes in both ESRD and non-ESRD groups.

Disease activity at the onset of diagnosis as a predictor of disease outcomes in a cohort of patients with systemic lupus erythematosus: A post hoc retrospective analysis of the COMOSLE-EGYPT study.

Systemic lupus erythematosus (SLE) has a non-uniform course directly reflected in changes in disease activity and anticipation of damage. To determine the impact of disease activity at the onset of disease diagnosis, measured by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) disease activity score, on different disease parameters and outcomes. This multicentre, retrospective cohort study included 823 SLE patients. Disease damage was measured by the Systemic Lupus International Collaborating Clinics Damage Index (SLICC), and comorbidities were measured by the Charlson Comorbidity Index (CCI). According to the mean SLEDAI at onset of disease diagnosis, patients were classified into two groups: I included patients with a mean SLEDAI ≤ 10 (non-severe disease activity), and II included patients with a mean SLEDAI > 10 (severe disease activity). SLEDAI at onset of disease diagnosis was a predictor of damage and comorbidities. A higher SLEDAI score at onset of disease diagnosis was associated with damage accrual. Patients who are younger at disease onset are more likely to have more severe disease. Severe disease activity at the onset of disease diagnosis was also associated with future comorbidity occurrences, but it was not significantly associated with mortality. SLEDAI at the onset of disease diagnosis could be a prognostic marker predicting the damage, which may help in the identification of patients who are at higher risk of adverse outcomes. Special care should be directed towards patients who are younger at disease onset as they may have a higher disease activity at diagnosis. Key Points • This is a unique study as it is the first to focus on the impact of SLE disease activity at the onset of disease diagnosis measured by SLEDAI disease activity score on different disease parameters and outcomes. • Previous studies, though these are scarce, have highlighted the impact of disease activity throughout the disease course and not specifically at the beginning of the SLE disease.

Out-of-hospital onset versus in-hospital onset for clinical outcomes in spontaneous intramuscular hematoma diagnosed by computed tomography: a retrospective cohort study.

The aging global population and the increasing use of antithrombotic agents have made spontaneous intramuscular hematomas (SIH) a growing concern. The association between the settings of SIH onset and clinical outcomes remains unclear. The aim of this study was to determine these associations. A retrospective cohort study was conducted in a tertiary hospital in Hiroshima, Japan between January 2008 and January 2022. We included consecutive patients aged ≥ 15years with SIH at any site diagnosed by computed tomography. The subjects were divided into two groups according to onset settings: out-of-hospital onset and in-hospital onset. The main outcome was treatment failure (composite of change in initial treatment and in-hospital death), and in-hospital mortality was also assessed. We used inverse probability of treatment weighting (IPTW) to estimate the causal effects of onset settings on outcomes. Of 84 included subjects with SIH, 63 had out-of-hospital onset and 21 had in-hospital onset. One subject (1.6%) with out-of-hospital onset and four subjects (19%) with in-hospital onset experienced treatment failure. In the IPTW cohort, in-hospital onset was associated with treatment failure [odds ratio (OR) 29, 95% confidence interval (CI) 7.2-270]. In addition, one subject (1.6%) with out-of-hospital onset and three subjects (14%) with in-hospital onset died during hospitalization. In-hospital onset was associated with a high rate of in-hospital mortality (OR 25, 95% CI 6.3-240) in the IPTW cohort. SIH with in-hospital onset had a poorer prognosis than that of SIH with out-of-hospital onset, suggesting that onset setting might be a novel predictor of clinical outcomes for SIH.

Frailty as an independent predictor for midterm adverse outcomes in the elderly undergoing primary percutaneous coronary intervention: A longitudinal cohort study.

Frailty is associated with poor health outcomes in elderly population. However, its effect on midterm outcomes in elderly patients undergoing primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) remains unknown. This study aimed to evaluate the association between frailty, as classified by the Clinical Frailty Scale (CFS), and midterm adverse outcomes in elderly STEMI patients after primary PCI. In this prospective, observational, multicenter cohort study, frailty status of 426 STEMI patients aged ≥60 years undergoing primary PCI was determined using the nine-point CFS 2 weeks before the occurrence of STEMI. Patients scoring at least four points on the CFS were considered frail. The primary outcome was a composite of cardiovascular death or readmission. Secondary outcomes included cardiovascular death, cardiovascular readmission, heart failure-related death or readmission, and myocardial reinfarction. Follow-up data were collected through medical record reviews and/or telephone interviews. Of 426 elderly patients, 116 were frail. The median follow-up period was 15 months (interquartile range 5-19 months). Primary outcome events occurred in 87 (75.0%) frail and 75 (24.2%) nonfrail patients. The adjusted hazard ratio was 3.278 after model selection using the Bayesian Model Averaging approach (95% confidence interval 2.372-4.531). Multivariate Cox proportional hazard survival analysis showed that frailty was significantly associated with a higher prevalence of all secondary outcome events after adjusting for TIMI, PAMI, and CADILLAC risk scores. Frailty, as defined by the CFS, was independently associated with midterm adverse outcomes in elderly patients undergoing primary PCI for STEMI.

Association of Pretreatment Perfusion Imaging Parameters With 90-Day Excellent Functional Outcomes in Anterior Circulation Distal Medium Vessel Occlusion Stroke.

Acute ischemic strokes caused by distal medium vessel occlusions (DMVO) represent a significant proportion of all stroke cases, yet the predictors of excellent functional outcomes in these patients remain poorly understood. This study aims to identify pretreatment computed tomography perfusion (CTP) parameters associated with excellent functional outcomes, defined as a modified Rankin Scale (mRS) score of 0-1 at 90 days, in patients with anterior circulation DMVO. We conducted a retrospective multicenter study involving patients with anterior DMVO, from three stroke centers within the Johns Hopkins Medical Enterprise. Baseline demographic, clinical, and imaging data were collected, with CTP parameters analyzed using RAPIDAI software. Univariable and multivariable logistic regression models were used to identify predictors of excellent outcomes. Receiver operating characteristic (ROC) curves were constructed to assess the predictive accuracy of CTP parameters. Among the 82 patients (median age, 71 years; 57% female), occlusions were located in the M2 segment in 89%, M3 in 8.5%, and A2 in 2.4%. IVT was administered to 37% of patients, and EVT was attempted in 59%. Excellent outcomes at 90 days were achieved in 45% of patients. In univariate analysis, white race (OR, 4.14; 95% CI, 1.66-10.9; P=0.003), higher CBV index (OR per 0.1-unit change, 1.45; 95% CI, 1.08-2.05; P=0.022), and lower relative cerebral blood flow (rCBF < 20%) volumes (OR, 0.91; 95% CI, 0.81-0.98; P=0.038) were significantly associated with excellent outcomes. In multivariate analysis adjusting for age, sex, race, IVT administration, EVT attempted, dyslipidemia, and premorbid mRS, higher CBV index remained a significant independent predictor (OR per 0.1-unit change, 1.72; 95% CI, 1.14-2.81; P=0.017), and lower rCBF < 20% volume was associated with better outcomes (OR, 0.91; 95% CI, 0.80-0.98; P=0.05). The multivariate model demonstrated good predictive performance (area under the ROC curve, 80%; 95% CI, 70%-90%; P < 0.001). In patients with anterior circulation DMVO, a higher CBV index on pretreatment CTP is an independent predictor of excellent functional outcomes at 90 days. These findings suggest that CTP parameters, particularly the CBV index, may be useful in prognostic assessment for this stroke population. Further studies are needed to validate these results and optimize therapeutic approaches. ABC＝ definition; XYZ＝ definition.

Serum Albumin and Body Mass Index as Predictors of Outcome in Peptic Perforation Surgeries: A Hospital Based Cross‐Sectional Study

Serum Albumin and Body Mass Index as Predictors of Outcome in Peptic Perforation Surgeries: A Hospital Based Cross‐Sectional Study

Pre-admission opioid use disorder as a new predictor of in-hospital mortality and six-month outcomes in traumatic brain injury patients: a retrospective longitudinal cohort study.

The present study aimed to investigate the effect of pre-admission Opioid Use Disorder (OUD) on in-hospital mortality and 6-month follow-up TBI outcomes. This study included 2804 patients with TBI admitted to the Intensive Care Unit of Emtiaz (Rajaee) Hospital, a referral trauma center in Shiraz, Iran. Finally, 1087 eligible participants were selected from included patients. Then, 872 discharged patients were followed for six months. Subsequently, unfavorable neurological outcomes (Glasgow Outcome Scale-Extended ≤ 4) and the mortality rate were compared among the patients with and without OUD. The mean age of the patients was 38.0 ± 18.9 years old (84.7% men). About 9.2% of patients had OUD. Opioid users had a slightly lower risk of in-hospital mortality (OR = 0.62, 95% CI = [0.328, 1.183], P-value = 0.148). In contrast, 6-month follow-up mortality significantly increased in the survived patients with a history of pre-admission OUD (OR = 2.49, 95%CI= [1.29, 2.80], P-value = 0.007). Moreover, 6-month unfavorable outcomes were raised in OUD, though it was not significant (OR = 1.59, 95%CI= [0.89, 2.84], P-value = 0.121). Our results revealed that patients with OUD are at increased risk of 6-month follow-up complications and also death following moderate to severe TBI. Although OUD decreased in-hospital mortality, 6-month follow-up indicated that mortality and unfavorable outcomes were increased in the OUD group. Based on the existing evidence, this effect is probably not only due to the destructive impact of pre-admission OUD on brain physiology. However, it may also be due to an increase in opioid consumption to alleviate pain and withdrawal symptoms after hospital discharge.

Examining the influence of intolerance of uncertainty on (occupational) future time perspective and retirement-related outcomes in working adults

Abstract Uncertainty regulation models have recently challenged the assumption that uncertainty is inherently negative, describing ways that uncertainty regulation can lead to effectiveness. The goal of this study was to empirically test a small component of these dynamic frameworks. We accomplished this through measuring intolerance of uncertainty—a predisposition towards fearing an uncertain future—as a predictor of retirement-related outcomes, via future time perspective and occupational future time perspective. In Study 1, based on a heterogenous two-wave sample of working adults, (T1 N = 975, T2 N = 875), we tested intolerance of uncertainty as a predictor of financial risk tolerance towards retirement, retirement saving behaviors, and motivation to continue working, via future time perspective. Study 1 revealed that intolerance of uncertainty had a significant indirect effect on motivation to continue working and financial risk tolerance towards retirement, via future time perspective—suggesting that tolerating uncertainty is beneficial for aging workers through shaping an open-ended future time perspective. In Study 2, we used a heterogenous three-wave sample of working adults (T1 N = 587, T2 N = 454, T3 N = 406) and evaluated intolerance of uncertainty as a predictor of perceived work ability, via occupational future time perspective. Consistent with expectations, Study 2 reinforced the conclusions of Study 1. Overall, we provide empirical support for aspects of these uncertainty regulation frameworks. We discuss our findings in the context of uncertainty regulation, (occupational) future time perspective, and successful workplace aging.

The Impact of Coronary Ischemia Assessment on Outcomes in Those With Scar-Dependent Ventricular Tachycardia.

Guidance and outcomes of coronary ischemia assessment (IA) in those with structural heart disease (SHD), presenting with monomorphic ventricular tachycardia (MMVT) is unclear. To assess the impact of IA on arrhythmic and non-arrhythmic outcomes in those with SHD. Patients presenting with MMVT over a 6-year period to a tertiary center were retrospectively analyzed. Propensity score-matched analysis was performed comparing those undergoing IA to those who did not. The primary endpoint was a composite of VT recurrence, appropriate ICD therapy, heart failure hospitalization, and death. Secondary analysis of the individual components of the composite was performed. Kaplan-Meier, univariate and multivariate analysis was performed to compare the two groups and derive predictors of poor outcomes. Two hundred and seventeen patients (57.6% ICM) were analyzed. 55.8% underwent IA. Following propensity score-matching, 120 patients remained. At 12 months, freedom from the primary endpoint was 68.3% of those undergoing IA versus 43.3% who did not, p < 0.001, multivariate HR 0.56 (0.34-0.92). This was driven by a reduction in all-cause mortality, with a 12-month survival of 98.3% in those undergoing IA versus 86.5% in those not undergoing IA (p < 0.01). Coronary intervention was associated with a significantly higher event-free 12-month survival compared to those who did not undergo intervention (82.4% vs 51.5%, respectively, p = 0.01). Patients with SHD presenting MMVT who undergo an IA have significantly improved freedom from VT recurrence, appropriate ICD therapies, HF hospitalization, and death compared to those who do not, driven by a reduction in mortality.

Prognostic value of morphology and hemodynamics in moyamoya disease for long-term outcomes and disease progression.

To explore the relationship between morphological and hemodynamic parameters, baseline characteristics, and long-term outcomes in patients with moyamoya disease (MMD) using a computational fluid dynamics model. We retrospectively reviewed 129 patients at Beijing Tiantan hospital between July 2020 and December 2021. Perioperative clinical variables and Suzuki stage were recorded. Logistic regression analysis was employed to identify the risk factors for unfavorable long-term outcomes. The association between morphological, CT perfusion parameters, hemodynamic parameters and the Suzuki stage, clinical variables of MMD was also analyzed. Patients with high relative Wall Shear Stress (rWSS) were older and had more cases with higher Suzuki stage and worse follow-up mRS scores (p < 0.05). High rWSS at the terminal ICA and diabetes mellitus were identified as independent predictors of unfavorable long-term outcomes [OR = 3.039(1.191-7.754), p = 0.020; OR = 3.164(1.141-8.723), p = 0.027, respectively]. ROC analysis demonstrated that predictive models incorporating rWSS improved AUC values, with the highest AUC in Model 2 (AUC = 0.889). High rWSS was significantly associated with future TIA and stroke events (p = 0.032). We speculated that high rWSS and diabetes mellitus were independent risk factors for unfavorable long-term outcomes in patients with MMD. rWSS and morphological parameters are crucial for predicting MMD progression and understanding its pathogenesis.

Longitudinal evaluation of hemodynamic blood and echocardiographic biomarkers for the prediction of BPD and BPD-related pulmonary hypertension in very-low-birth-weight preterm infants.

Mainly at an early stage of postnatal neonatal care in VLBW preterm infants, several biomarkers were found to be associated with the combined endpoint BPD/death and BPD-PH. New candidates of blood biomarkers (NTproBNPZlog, ET-1, and CA125) and echocardiographic markers (TAPSE, PAAT/RVET) might serve as innovative predictors for BPD, BPD-PH, and adverse outcomes in VBLW infants. • VLBW infants are at risk for the development of BPD and BPD-related PH, which both are main contributors for short and long-term morbidity and mortality. Several studies in the past focused on the evaluation of circulating blood biomarkers and biomarkers from echocardiographic assessment of these infants. But to date, there is still a lack on longitudinal prospective studies especially in VLBW infants. • For the first time, this set of selected blood biomarkers (with the first description of Zlog-transformed NTproBNP and CA125 in preterm infants) and several echocardiographic markers were analyzed in a prospective longitudinal study from birth until 36 weeks post menstrual age in VLBW infants. Our data help clinicians to identify preterm infants at risk for BPD, BPD-PH and death and to offer new candidates of biomarkers. This might help to facilitate decision making and guidance of therapy in these highly vulnerable patients.

PREDICTIVE MARKERS FOR ADVERSE PREGNANCY OUTCOMES: INSIGHTS FROM A PROSPECTIVE COHORT STUDY ON MATERNAL FACTORS, BIOMARKERS, AND UTERINE ARTERY DOPPLER RESULTS

Objective: Effective prediction tools are necessary for better outcomes when it comes to pregnancy-related complications such as intrauterine growth restriction (IUGR), pregnancy-induced hypertension (PIH), and premature birth. In order to improve early risk diagnosis and treatment, this study investigates relationships between maternal variables, first-trimester biomarkers, and second-trimester uterine artery Doppler findings. Methods: Correlations between demographic characteristics, maternal dual test indicators (serum beta-HCG, serum PAPPA), and uterine artery Doppler tests were examined in a prospective cohort study including 500 pregnant women. Statistical studies evaluated correlations with IUGR, PIH, and premature birth. Results: Serum beta-HCG levels below the 5th percentile correlated significantly with preterm birth (RR 2.3131, p = 0.0288). Low serum PAPP-A levels (&lt;5th percentile) associated with PIH (RR 2.1447, p = 0.0204) and IUGR (RR 2.0953, p = 0.0002). Uterine artery Doppler indices (&gt;0.58 RI) demonstrated associations with PIH (RR 2.2448) and IUGR (RR 1.6293). Diastolic notching correlated with preterm birth, PIH, and IUGR. Conclusion: The potential of serum beta-HCG, PAPP-A, and uterine artery Doppler indices as useful predictors of unfavorable pregnancy outcomes is highlighted by this study, which also highlights their use in early risk detection.

Penile length after penile implant surgery is determined by stretched penile length before surgery.

While various treatment modalities exist, penile prosthesis (PP) implantation offers a permanent solution for patients that do not respond to or are not suitable for other treatment options for erectile dysfunction. The aim of this study was to establish stretched penile length before surgery as a reliable determining factor of penile length after penile implant surgery. For this study, data on penile length before and after PP surgery from three European centers was analyzed. Penile length measurements were conducted preoperatively and postoperatively in different conditions using standardized techniques. Only virgin cases were included and a complete case analysis was performed. The outcome of this study was the comparison of stretched penile length before and the inflated penile length after PP surgery. Data on penile length before and after PP of 361 patients was analyzed. Preoperative stretched penile length was equal to postoperative inflated penile length in 33% of patients. The absolute mean difference between pre-surgery stretched and postoperative inflated lengths was 1.1cm. No correlation was found between implanted cylinder length and postoperative penile length. Additionally, the choice of implant type did not significantly affect postoperative penile length outcomes. Our findings confirm the reliability of preoperative stretched penile length as a tool for proper patient counseling before PP surgery. Although our study is overpowered, our results show that preoperative stretched penile length serves as a reliable predictor of postoperative penile length outcomes after PP surgery. By providing clinicians with a tool for patient counseling, our findings contribute to enhancing satisfaction and quality of life outcomes in patients undergoing PP implantation. Preoperative stretched penile length serves as a reliable predictor of postoperative penile length outcomes after PP surgery.

Predictors of outcomes after gastric peroral endoscopic myotomy for refractory gastroparesis: a systematic review

Background: Gastroparesis is a debilitating gastroduodenal disorder for which gastric peroral endoscopic myotomy (GPOEM) has emerged as an efficacious treatment option. However, response to GPOEM varies between 50-80%, such that preoperative predictors of treatment success are needed to guide patient selection. Methods: We performed a systematic review to identify predictors of clinical and functional response to GPOEM among adult patients with gastroparesis (PROSPERO: CRD42023457359). MEDLINE, Embase, and CENTRAL databases were searched systematically for studies reporting outcomes after GPOEM in September 2023. A narrative synthesis of predictive factors on univariable and multivariable analysis was performed with consideration of response rates via meta-analysis, and evaluation of discrimination if prognostic models were developed. ROBINS-E was used for risk of bias assessment. Results: Of 1899 articles reviewed, 30 were included. The GPOEM response rate was 63.1% (95% confidence interval 56.3%-69.5%) with most studies defining clinical success on the basis of improvement in gastroparesis cardinal symptom index (87%, 26/30). Older age, shorter duration of gastroparesis, non-diabetic etiology, lower body mass index, and response to intrapyloric botulinum toxin were associated with positive response to GPOEM on multivariable analyses. Predictors on physiological tests such as EndoFLIP or gastric emptying scintigraphy were inconsistent. No prognostic models underwent external validation. Conclusion: Currently, there are limited reproducible predictors of response to GPOEM among patients with refractory gastroparesis. Robust prospective studies investigating scalable, reproducible, and actionable biomarkers of treatment response are required.

The California collaborative network to promote data driven care and improve outcomes in early psychosis (EPI-CAL) project: rationale, background, design and methodology.

A prolonged first episode of psychosis (FEP) without adequate treatment is a predictor of poor clinical, functional, and health outcomes and significant economic burden. Team-based "coordinated specialty care" (CSC) for early psychosis (EP) has established effectiveness in promoting clinical and functional recovery. However, California's CSC program implementation has been unsystematic and could benefit from standardizing its processes and data collection infrastructure. To address this, we established a consortium of EP clinics across the state via a Learning Health Care Network (LHCN) framework to develop the Early Psychosis Intervention Network of California (EPI-CAL). EPI-CAL's LHCN developed a core battery of evidence-based measures for service users and family members and linked them together using a unique data collection and visualization application, Beehive. EPI-CAL's LHCN collects, visualizes, and aggregates data at the individual and clinic level for EP programs across California via Beehive. Beehive was designed to: (1) collect outcomes data from service users receiving care at EP programs and their support persons, (2) provide the data to providers on a secure web-based dashboard to support measurement-based care, and (3) allow data to be used for program or research analysis. We will (1) determine the feasibility of implementing an LHCN across a diverse, decentralized network of early psychosis programs, (2) determine if the implementation of an LHCN increases the delivery of measurement-based care, and (3) determine if the implementation of measurement-based care is associated with significant improvements in key service user outcomes. EPI-CAL's network will contribute data to the Early Psychosis Intervention Network (EPINET) program. The current study aims to establish an LHCN of EP clinics in California that implements harmonized data collection using Beehive and assesses the feasibility of establishing such a network. Our goal is for this harmonized data collection approach to be used to inform decisions and develop learning opportunities for service users, staff, and administrators, and to improve outcomes for service users and their supporters in CSC care. Further, the data will enable programs and research teams to examine what elements of care lead to program success and improved treatment outcomes for service users. www. gov , identifier NCT04007510; registered 07/05/2019.

Abstract A006: Development of a syngeneic transplant rat model for the identification of an mRNA signature associated with metastatic hepatocellular carcinoma

Abstract Approximately 70% of patients with hepatocellular carcinoma (HCC) die of metastasis, mainly in the lung, due in part to late diagnosis. Therefore, in vivo models that are representative of metastatic HCC biology in patients must include factors that are essential for metastasis development, such as an immunocompetent system and a tumor microenvironment with homotypic interactions. This will allow the identification of new prognostic biomarkers for patients with metastatic HCC that are efficient and accessible. We developed two hepatocellular carcinoma cell lines for syngeneic transplant models in immunocompetent rats: Samy (nonmetastatic) and Samy Met (metastatic). These cell lines allow the development of cancer and metastasis in a homotypic environment with a complete immune system; therefore, they are expected to be representative of what happens in patients with metastatic HCC. Both cell lines were biologically characterized, and the primary tumors they produced were used in a comparative transcriptomic study to identify a metastatic HCC molecular signature that may function as a prognostic biomarker. The differentially expressed genes (DEGs) were related to relevant biological processes, such as metastasis, cancer stem cells (CSCs), and tumor growth, and all of these processes are essential for cancer progression. Among the top 50 DEGs, an mRNA firm was assembled, including 3 upregulated genes (ITGB6, SEMA3F, and NDC80) and 7 downregulated genes (COL15A1, ATP13A4, C18ORF26, PRKG2, ITM2A, IGSF9B, and CNTN1). The firm was related to poor survival in patients with HCC and had good accuracy in predicting macrovascular invasion, which is a strong predictor of poor HCC outcome, both after surgical resection and after liver transplantation.

Effect of Patient Resilience on Functional Outcomes After Anterior Cruciate Ligament Reconstruction.

Previous studies have examined the relationship between patient resilience and functional outcome scores after anterior cruciate ligament reconstruction (ACLR). However, past studies have failed to explore the longitudinal relationship between preoperative resilience and functional outcomes 2 years after ACLR. To evaluate the relationship between preoperative patient resilience and functional outcomes 2 years after ACLR. Cohort study; Level of evidence, 3. Patients were identified who underwent ACLR for anterior cruciate ligament tears between January and June 2020 at a single institution. Those who completed the Brief Resilience Scale preoperatively as part of routine patient questionnaires were considered for inclusion. Patients were contacted a minimum of 2 years after ACLR to complete the short form of the Knee injury and Osteoarthritis Outcome Score (KOOS-JR), Single Assessment Numeric Evaluation (SANE), International Knee Documentation Committee (IKDC) Subjective Knee Form, and visual analog scale (VAS). Outcomes were compared among patients with low resilience (LR), normal resilience (NR), and high resilience (HR), as defined in a previous study.23. A total of 81 patients were included in the final analysis, with 14 patients in the low preoperative resilience group, 54 in normal, and 13 in high. The mean age of the cohort was 32.0 years, and there were no significant differences in age, sex, race, graft type, or psychiatric comorbidities among the resilience groups. Significantly increased postoperative KOOS-JR scores were observed in patients in the HR group as compared with those in the NR and LR groups (94.8, 86.7, and 79.6, respectively; P = .031). There were also significantly increased postoperative SANE scores in patients in the HR group versus those in the NR and LR groups (92.3, 83.5, and 69.2; P = .012). Patients with high preoperative resilience achieved the IKDC Patient Acceptable Symptom State at significantly higher rates (P = .003). No significant differences were observed in postoperative VAS (P = .364), IKDC (P = .072), or change in IKDC (P = .448) over time among resilience groups. Postoperatively, 30 patients (37.0%) changed resilience groups, with 13 moving down and 17 moving up in category (low, n = 12; normal, n = 55; high, n = 14). Preoperative resilience correlated with KOOS-JR and SANE scores 2 years after ACLR but did not correlate with VAS, IKDC, or change in IKDC over the same period. Resilience was not static, with changes in resilience observed from initial to final evaluations. Resilience is not a strong predictor of postoperative patient-reported outcomes after ACLR.

THE RELATIONSHIP BETWEEN RETINAL PERFUSION AND FUNCTIONAL RECOVERING OF FOVEA IN DIFFERENT TYPES OF SURGICAL CLOSURE OF FULL-THICKNESS MACULAR HOLES

Rationale: The effect of retinal perfusion on functional recovery of the fovea, as well as the value of quantitative perfusion parameters as predictors of functional outcome in the surgical treatment of full-thickness macular holes (FTMH) remains poorly understood.Objective: To study the relationship between changes in retinal perfusion and functional parameters of the fovea in the postoperative period at 1 and 2 types of FTMH closure.Methods: A prospective study including 93 patients (93 eyes) with idiopathic FTMH stage 2-4 according to D. Gass after surgical treatment. In subgroups with type 1 and type 2 of FTMH closure, changes in the foveal avascular zone (FAZ) area and vessel density in the superficial and deep capillary plexuses (SCP and DCP) in the fovea, changes in BCVA, retinal sensitivity (RS) at the fixation point, and P1 amplitude in the fovea were studied. Studies were performed preoperatively, 1 and 6 months after surgery. A significant correlation was found between the changes in BCVA, RS at the fixation point, P1 amplitude in the fovea, and changes in vessel density in the SCP and DCP, which was more pronounced in the period from 1 to 6 months after surgery. The correlation of the changes in the parameters is higher in type 2 of FTMH closure than in type 1 of FTMH closure.Results:. Subgroups with type 1 and type 2 FTMH closure included 67 and 26 eyes, respectively. Type 2 FTMH closure showed lower vascular density in the DCP before (p=0.02) and 6 months after surgery (p=0.03), lower BCVA before surgery (p=0.03), 1 and 6 months after surgery (p &lt;0.001), lower RS at the fixation point before and after surgery (p&lt;0.002).Conclusion. In type 2 macular hole closure, postoperative changes in retinal perfusion have a more pronounced impact on functional recovery of the fovea, especially in the late postoperative period.
